Citation Nr: 0924236 Decision Date: 06/26/09 Archive Date: 07/01/09 DOCKET NO. 04-13 922 ) DATE ) ) On appeal from the Department of Veterans Affairs Regional Office in Detroit, Michigan THE ISSUE Entitlement to service connection for the cause of the Veteran's death. REPRESENTATION Appellant represented by: Veterans of Foreign Wars of the United States ATTORNEY FOR THE BOARD T. Wishard, Associate Counsel INTRODUCTION The Veteran served on active duty from January 1963 to January 1966. The Veteran died in December 1998. The appellant is the Veteran's surviving spouse. This matter comes before the Board of Veterans' Appeals (Board) from a June 2003 rating decision of the Department of Veterans Affairs (VA), Regional Office (RO) in Philadelphia, Pennsylvania. This matter was previously before the Board in August 2005 and May 2007 and was remanded for further development. It has now returned to the Board for further appellate consideration. FINDINGS OF FACT 1. The certificate of death reflects that the Veteran died on December [redacted], 1998 as a result of sepsis, due to liver failure, due to cancer of the pharynx, and pneumonia. 2. At the time of the Veteran's death, service-connection had not been established for any disability; however, in an August 2008 rating decision, service connection was posthumously established for diabetes mellitus associated with herbicide exposure, with a 20 percent evaluation, for accrued benefits purposes, based on a claim pending at the time of the Veteran's death. 3. Cancer of the tongue, with metastasis to the pharynx, is not shown by competent medical evidence to be linked to service; and is not shown to have been caused or aggravated by the Veteran's exposure to Agent Orange, or any other herbicide. 4. Sepsis, liver failure, and pneumonia are not shown by competent medical evidence to be causally related to service, to include as secondary to diabetes mellitus. 5. The competent evidence does not establish that a service- connected disability was either the principal or a contributory cause of the Veteran's death, nor is there competent medical evidence establishing that the cause of his death was incurred or aggravated in service. CONCLUSION OF LAW The cause of the Veteran's death was not incurred in or aggravated by active service, and may not be presumed to have been so incurred or aggravated. 38 U.S.C.A. 38 U.S.C.A. §§ 1101, 1110, 1112, 1113, 1137, 1310 (West 2002 & West Supp. 2008); 38 C.F.R. §§ 3.303, 3.304, 3.307, 3.309, 3. 312 (2008). REASONS AND BASES FOR FINDINGS AND CONCLUSION The Veterans Claims Assistance Act of 2000 (VCAA) describes VA's duty to notify and assist claimants in substantiating a claim for VA benefits. 38 U.S.C.A. §§ 5100, 5102, 5103, 5103A, 5107, 5126 (West 2002 & Supp. 2008); 38 C.F.R. §§ 3.102, 3.156(a), 3.159 and 3.326(a) (2008). Duty to Notify Upon receipt of a complete or substantially complete application for benefits, VA is required to notify the claimant and his or her representative, if any, of any information, and any medical or lay evidence, that is necessary to substantiate the claim. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b); Quartuccio v. Principi, 16 Vet. App. 183 (2002). Proper VCAA notice must inform the claimant of any information and evidence not of record (1) that is necessary to substantiate the claim; (2) that VA will seek to provide; and (3) that the claimant is expected to provide. VCAA notice should be provided to a claimant before the initial unfavorable agency of original jurisdiction (AOJ) decision on a claim. Pelegrini v. Principi, 18 Vet. App. 112 (2004); see also Mayfield v. Nicholson, 19 Vet. App. 103 (2005), rev'd on other grounds, 444 F.3d 1328 (Fed. Cir. 2006). In March 2006, the United States Court of Appeals for Veterans Claims (Court) issued its decision in the consolidated appeal of Dingess/Hartman v. Nicholson, 19 Vet. App. 473 (2006). The Court in Dingess/Hartman held that the VCAA notice requirements of 38 U.S.C. § 5103(a) and 38 C.F.R. § 3.159(b) apply to all five elements of a "service connection" claim. As previously defined by the courts, those five elements include: (1) Veteran status; (2) existence of a disability; (3) a connection between the Veteran's service and the disability; (4) degree of disability; and (5) effective date of the disability. Upon receipt of an application for service connection, therefore, VA is required to review the information and the evidence presented with the claim and to provide the claimant with notice of what information and evidence not previously provided, if any, will assist in substantiating or is necessary to substantiate the elements of the claim as reasonably contemplated by the application. This includes notice that a disability rating and an effective date for the award of benefits will be assigned if service connection is awarded. In Hupp v. Nicholson, 21 Vet. App. 342 (2007), the Court expanded the VCAA notice requirements for a Dependency and Indemnity Compensation (DIC) claim. In Hupp, the Court held that, when adjudicating a claim for DIC, VA must perform a different analysis depending upon whether a Veteran was service-connected for a disability during his or her lifetime. The Court concluded that, in general, section 5103(a) notice for a DIC case must include: (1) a statement of the conditions, if any, for which a Veteran was service- connected at the time of his or her death; (2) an explanation of the evidence and information required to substantiate a DIC claim based on a previously service-connected condition; and (3) an explanation of the evidence and information required to substantiate a DIC claim based on a condition not yet service-connected. In addition, the Court found that the content of the section 5103(a) notice letter will depend upon the information provided in the claimant's application. In VA correspondence to the appellant in August 2005 and May 2007, VA informed the appellant of what evidence was required to substantiate her claim and of her and VA's respective duties for obtaining evidence. The August 2005 correspondence to the appellant was deficient in that it did not include the criteria for assignment of an effective date, in the event of award of the benefit sought, as required by the Court in Dingess/Hartman. This information was provided in the May 2007 correspondence. In addition, the above referenced VA correspondence did not inform the appellant of the disabilities, if any, for which the Veteran was service-connected at the time of his death. The Board finds that this error has been rendered harmless, and the appellant has not been prejudiced by a lack of proper notice in accordance with Hupp. The evidence of record includes a letter, dated in November 1996, from the appellant to VA, which reflects that the appellant was aware that the Veteran had a claim pending for entitlement to service connection for diabetes mellitus. The Veteran died in December 1998. In September 2000 VA correspondence to the appellant, VA notified her that her claim for death benefits had been denied. The enclosed August 2000 rating decision reflected that the Detroit, Michigan RO denied the Veteran's pending claims for entitlement to service connection for squamous cell carcinoma, diabetes, and a liver condition. In November 2001, the appellant's representative requested reconsideration of the August 2000 rating decision regarding diabetes. By a rating decision dated in August 2008, service connection was established for diabetes mellitus for accrued benefits purposes. Thus, the appellant was aware that at the time of the Veteran's death, he had a claim for diabetes mellitus pending; and that his claim was later granted; therefore, the Board finds that the appellant was not prejudiced by lack of proper notice in accordance with Hupp. See Shinseki v. Sanders/Simmons, No. 07-1209 (U.S. Sup. Ct. Apr. 21, 2009); 556 U.S. ____ (2009); Fenstermacher v. Phila. Nat'l Bank, 493 F.2d 333, 337 (3d Cir. 1974) ("[N]o error can be predicated on insufficiency of notice since its purpose had been served."). In order for the Court to be persuaded that no prejudice resulted from a notice error, "the record must demonstrate that, despite the error, the adjudication was nevertheless essentially fair." Dunlap v. Nicholson, 21 Vet. App. 112, 118 (2007). Because VCAA notice in this case was not completed prior to the initial AOJ adjudication denying the claim, the timing of the notice does not comply with the express requirements of the law as found by the Court in Pelegrini. Here, the Board finds that any defect with respect to the timing of the VCAA notice was harmless error. Although notice was provided to the appellant after the initial adjudication, the claim was readjudicated thereafter, and the appellant therefore, has not been prejudiced. The appellant has been provided with every opportunity to submit evidence and argument in support of her claim, and to respond to VA notice. All the VCAA requires is that the duty to notify is satisfied, and that claimants are given the opportunity to submit information and evidence in support of their claims. Once this has been accomplished, all due process concerns have been satisfied. See Bernard v. Brown, 4 Vet. App. 384 (1993); Sutton v. Brown, 9 Vet. App. 553 (1996). Duty to assist With regard to the duty to assist, the claims file contains the Veteran's death certificate, service treatment records (STRs), private medical opinions, VA medical opinions, lay statements from relatives of the Veteran, copies of internet articles, and the transcript of an August 1997 Travel Board hearing with the Veteran. Additionally, the claims file contains the appellant's statements in support of her claim. The Board has carefully reviewed such statements and concludes that she has not identified further evidence not already of record. Based on the foregoing, the Board finds that all relevant facts have been properly and sufficiently developed in this appeal and no further development is required to comply with the duty to assist the appellant in developing the facts pertinent to her claim. Essentially, all available evidence that could substantiate the claim has been obtained. There is no indication in the file that there are additional relevant records that have not yet been obtained. Legal criteria Service connection- in general Service connection is warranted if it is shown that a Veteran has a disability resulting from an injury incurred or a disease contracted in active service or for aggravation of a pre-existing injury or disease in active military service. 38 U.S.C.A. §§ 1110, 1131(West 2002); 38 C.F.R. § 3.303 (2006). Service connection may also be granted for any disease diagnosed after discharge when all of the evidence establishes that the disease was incurred in service. See 38 C.F.R. § 3.303(d). Where a Veteran served continuously for 90 days or more during a period of war, or during peacetime service after December 31, 1946, and some diseases, such as a malignant tumor, becomes manifest to a degree of 10 percent or more within one year from the date of termination of such service, such disease shall be presumed to have been incurred in or aggravated by service, even though there is no evidence of such disease during the period of service. This presumption is rebuttable by affirmative evidence to the contrary. 38 U.S.C.A. §§ 1101, 1110, 1112, 1113, 1137 (West 2002); 38 C.F.R. §§ 3.307, 3.309 (2008). If there is no evidence of a chronic condition during service, or during an applicable presumptive period, then a showing of continuity of symptomatology after service is required to support the claim. See 38 C.F.R. § 3.303(b). Evidence of a chronic condition must be medical, unless it relates to a condition to which lay observation is competent. See Savage v. Gober, 10 Vet. App. 488, 495-498 (1997). In each case where service connection for any disability is being sought, due consideration shall be given to the places, types, and circumstances of such Veteran's service as shown by such Veteran's service record, the official history of each organization in which such Veteran served, such Veteran's medical records, and all pertinent medical and lay evidence. 38 U.S.C.A. § 1154(a). Presumptive service connection - herbicide exposure VA regulations provide that certain diseases associated with exposure to herbicide agents may be presumed to have been incurred in service even if there is no evidence of the disease in service, provided the requirements of 38 C.F.R. § 3.307(a)(6) are met. 38 C.F.R. § 3.309(e) (2008). A Veteran who, during active service, served in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975, shall be presumed to have been exposed during such service to an herbicide agent, unless there is affirmative evidence to establish that the veteran was not exposed to any such agent during that service. 38 C.F.R. § 3.307(a). The last date on which such a Veteran shall be presumed to have been exposed to an herbicide agent shall be the last date on which he or she served in the Republic of Vietnam during the period beginning on January 9, 1962 and ending on May 7, 1975. The term "herbicide agent" means a chemical in an herbicide, including Agent Orange, used in support of the United States and allied military operations in the Republic of Vietnam during the Vietnam era. If a Veteran was exposed to an herbicide agent during active service, the following diseases shall be service-connected if the requirements of 38 C.F.R. § 3.307(a)(6) are met, even though there is no record of such disease during service, provided further that the rebuttable presumption provisions of 38 C.F.R. § 3.307(d) are also satisfied: Chloracne or other acneform disease consistent with chloracne; Type 2 diabetes (also known as Type II diabetes mellitus or adult- onset diabetes); Hodgkin's disease; chronic lymphocytic leukemia; multiple myeloma; non-Hodgkin's lymphoma; acute and subacute peripheral neuropathy; porphyria cutanea tarda; respiratory cancers (cancer of the lung, bronchus, larynx or trachea); and soft-tissue sarcoma (other than osteosarcoma, chondrosarcoma, Kaposi's sarcoma, or mesothelioma). 38 C.F.R. § 3.309(e). The diseases listed at 38 C.F.R. § 3.309(e) shall have become manifest to a degree of 10 percent or more at any time after service, except that chloracne or other acneform disease consistent with chloracne, porphyria cutanea tarda, and acute and subacute peripheral neuropathy shall have become manifest to a degree of 10 percent or more within a year after the last date on which the Veteran was exposed to an herbicide agent during active military, naval, or air service. 38 C.F.R. § 3.307(a)(6)(ii). Where the evidence does not warrant presumptive service connection, the United States Court of Appeals for the Federal Circuit has determined that an appellant is not precluded from establishing service connection with proof of direct causation. Combee v. Brown, 34 F.3d 1039 (Fed. Cir. 1994). Cause of Death The death of a Veteran will be considered as having been due to a service-connected disability when the evidence establishes that such disability was either the principal or a contributory cause of death. See 38 U.S.C.A. § 1310; 38 C.F.R. § 3.312(a). For a service-connected disability to be considered the primary cause of death, it must singly, or with some other condition, be the immediate or underlying cause, or be etiologically related thereto. 38 C.F.R. § 3.312(b). In determining whether a service-connected disability contributed to death, it must be shown that it contributed substantially or materially, that it combined to cause death, or that it aided or lent assistance to the production of death. 38 C.F.R. § 3.312(c)(1). Service-connected diseases or injuries involving active processes affecting vital organs should receive careful consideration as a contributory cause of death, the primary cause being unrelated, from the viewpoint of whether there were resulting debilitating effects and general impairment of health to an extent that would render the person materially less capable of resisting the effects of other disease or injury primarily causing death. Where the service-connected condition affects vital organs as distinguished from muscular or skeletal functions and is evaluated as 100 percent disabling, debilitation may be assumed. 38 C.F.R. § 3.312(c)(3). Medical evidence is required to establish a causal connection between service or a disability of service origin and the Veteran's death. See Van Slack v. Brown, 5 Vet. App. 499, 502 (1993). Analysis The Board has reviewed all of the evidence in the claims file. Although the Board has an obligation to provide reasons and bases supporting this decision, there is no need to discuss, in detail, the extensive evidence of record. Indeed, the Federal Circuit has held that the Board must review the entire record, but does not have to discuss each piece of evidence. Gonzales v. West, 218 F.3d 1378, 1380-81 (Fed. Cir. 2000). Therefore, the Board will summarize the relevant evidence where appropriate, and the Board's analysis below will focus specifically on what the evidence shows, or fails to show, as to the claim. The appellant is claiming entitlement to service connection for the cause of the Veteran's death. The Veteran's certificate of death lists the immediate cause of death as sepsis, due to liver failure, due to cancer of the pharynx, and pneumonia. The appellant contends that the Veteran's December 1998 death from sepsis was related to the Veteran's service-connected diabetes mellitus. Diabetes is not listed as an immediate cause of death, a condition leading to the immediate cause of death, or as a significant condition contributing to death, on the death certificate. The appellant also contends that the Veteran's cancer of the pharynx was caused by his exposure to herbicides while in Vietnam, and as such should be service-connected. Diabetes The Board will first discuss the appellant's claim that the Veteran's service-connected diabetes mellitus was a cause of his death. In August 2008, after the Veteran's death, service-connection was established for diabetes mellitus for accrued benefits purposes; however, the competent medical evidence of record does not reflect that the Veteran's service-connected disability was a principal or a contributory cause of death. The claims file includes opinions from three physicians. First, the evidence of record includes January 2002 correspondence from Dr. L.G. The correspondence reflects that the Veteran, upon diagnosis in November 1978, was initially placed on neutral protamine Hagedorn (NPH) insulin. Dr. L.G. further noted that an April 1985 hospital record reflects that the Veteran was just on oral Diabinese for the diabetes, and on May 1998, about seven months before he died, hospital records showed that the Veteran was no longer on any medication to control his diabetes. His fasting blood sugar level at that time was 141 mg/di. No opinion as to the Veteran's cause of death was given in the January 2002 correspondence. In October 2003 correspondence, Dr. L.G. opined that "upon further review of [the Veteran's] hospital chart, it appeared that his blood sugar was quite high at the time of his death. He was a known diabetic since 1978. It is therefore just as likely, as it is not as likely that his diabetic condition contributed to the cause of his death." Second, the evidence of record includes a March 2007 private medical opinion by Dr. C.N.B. The opinion, titled independent medical evaluation, reflects the following: It is my opinion that his diabetes absolutely and significantly contributed to [the Veteran's] demise as it is well known that widely abnormal blood and urine sugar levels, such as his levels of 408, 282, 267, 309, 203, 232, 4+ urine, 2+ urine ketones (as per the attached lab results), cause exacerbations in sepsis and pneumonia. Diabetes is associated with a relative immune -compromised state, which interferes with the body's ability to mount an immune response. This patient's altered immune response likely hastened his death by way of uncontrolled/ unmodulated infections - sepsis. In other words, his immune system was compromised due to his diabetes, which caused his sepsis and death. This patient died from sepsis and pneumonia, which is a form of uncontrolled infection, and it is my opinion, that his uncontrolled infection was due to his diabetes and associated abnormal blood sugar control. Third, the evidence of record includes a VA examiner's opinion dated in June 2006. The opinion reflects that the examiner reviewed the Veteran's claims file and medical records, including the opinion of Dr. L.G. The examiner noted that December 1998 records, prior to the Veteran's death, revealed high random blood sugar once, on the morning before the Veteran died. He received 50 milliliters of glucose with 10 units regular insulin, and Kayexalate for the management of hyperkalemia. No documentation of diabetes or its management is noted in the admission note on that date or on the subsequent available progress notes. The examiner opined that it is not at least as likely as not that the Veteran's diabetes mellitus contributed to the Veteran's death. The evidence of record includes a subsequent opinion by the same VA examiner, dated in January 2009, which reflects that the examiner reviewed the Veteran's claims file, his previous opinion, and the opinions of Dr. C.N.B. and Dr. L.G. The examiner noted that the abnormal blood and urine sugar levels mentioned by Dr. C.N.B. are very old lab reports. The examiner again opined that the Veteran's "diabetes mellitus less than likely as not contributed, aided or lent assistance to the production of his death, or hastened his death." As is true with any piece of evidence, the credibility and weight to be attached to this opinion is within the province of the adjudicator. Guerrieri v. Brown, 4 Vet. App. 467, 470-71 (1993). There is no requirement that additional evidentiary weight be given to the opinion of a medical provider who treats a Veteran; courts have repeatedly declined to adopt the "treating physician rule." See White v. Principi, 243 F.3d 1378, 1381 (Fed. Cir. 2001). Greater weight may be placed on one physician's opinion over another depending on factors such as reasoning employed by the physicians and whether or not and the extent to which they reviewed prior clinical records and other evidence. Gabrielson v. Brown, 7 Vet. App. 36, 40 (1994). In weighing the probative value of the medical opinions noted above, the Board finds that the opinions of the VA physician, dated in June 2006 and January 2009, have more probative weight than the opinions of the private physicians, Dr. L.G. and Dr. C.N.B.. The Board finds that the January 2002 correspondence from Dr. L.G. is not an opinion, but a recitation of facts; as such, it holds no probative weight as to the cause of the Veteran's death. The Board also finds that the October 2003 correspondence by Dr. L.G. lacks probative value. No rationale was provided for Dr. L.G.'s opinion that "it is just as likely as it is not as likely" that the Veteran's diabetes contributed to the cause of his death. Although Dr. L.G. noted that the Veteran had a high blood sugar level at the time of his death, and had been diagnosed with diabetes in 1978, he did not give adequate supporting rationale as to how these two facts could have contributed to the Veteran's death. The Board also finds that the opinions of the VA examiner are more probative than the opinion of Dr. C.N.B. The Board notes that Dr. C.N.B.'s opinion was based on a review of the Veteran's claim file, including his STRs and post service medical records. As noted above, Dr. C.N.B.'s opinion noted "widely abnormal blood and urine sugar levels, such as [the Veteran's] levels of 408, 282, 283, 267, 309, 203, 232, 4 plus urine sugar, and 2 plus ketones. As noted by the VA examiner, in his January 2009, opinion, these sugar levels are from "very old lab reports." The evidence of record reflects that the above mentioned levels were from November 1978, when the Veteran was initially diagnosed with diabetes, and more than 10 years prior to the Veteran's death. Because Dr.C.N.B. relied on the Veteran's sugar counts from his initial diagnosis date, and the evidence of record does not reflect that he considered the Veteran's treatment for diabetes, or more recent blood sugar levels, the Board finds that it lacks probative weight. Finally, the Board acknowledges that the evidence of record includes internet articles discussing type 2 diabetes. Assuming, arguendo, that the internet articles rise to the level of a medical article or medical treatise, the Board notes that the Court has held that a medical article or treatise "can provide important support when combined with an opinion of a medical professional" if the medical article or treatise evidence discusses generic relationships with a degree of certainty such that, under the facts of a specific case, there is at least "plausible causality" based upon objective facts rather than on an unsubstantiated lay medical opinion. Mattern v. West, 12 Vet. App. 222, 228 (1999). See also Sacks v. West, 11 Vet. App. 314 (1998); Wallin v. West, 11 Vet. App. 509 (1998). In short, articles and treatises tend to be general in nature and tend not to relate to the specific facts in a given Veteran's claim. In the present case, the articles fall into this general category. Although the articles discuss type 2 diabetes and its relationship with liver disease, pneumonia, and sepsis, none of the articles pertain specifically to this Veteran Therefore, this evidence is not probative with regard to the issue here on appeal. Carcinoma of the Pharynx The appellant also contends that the Veteran's cancer of the pharynx is due to Agent Orange exposure; hence, she contends that it should be service connected. The Veteran was not service-connected for cancer at the time of his death. The evidence of record reflects that the Veteran was diagnosed with squamous cell carcinoma of the hypopharynx in 1996, 30 years after his separation from service. In a December 1997 Board decision, entitlement to service connection for squamous cell carcinoma of the tongue, with metastasis to the neck, as a residual of Agent Orange exposure was denied. The Board will first consider the presumption of herbicide exposure. The Veteran's DD Form 214 reflects that he received the Vietnam Service Medal. There is no military document verification that the Veteran had service within the Republic of Vietnam; however, the claims file contains his lay statements regarding his service in Vietnam, as well as a VA letter, dated in February 1985, which reflects that the Veteran participated in the VA's Agent Orange registry. Thus, the Board concedes that the Veteran served in the Republic of Vietnam. Therefore, it is presumed that he was exposed to an herbicide agent. See 38 C.F.R. § 3.307(a)(6)(iii). Moreover, affirmative evidence does not exist to rebut that presumption. Despite presumed exposure to an herbicide agent, presumptive service connection under 38 C.F.R. § 3.307(a)(6) is not warranted. Service connection is only warranted on this presumptive basis for a specific list of diseases set forth under 38 C.F.R. § 3.309(e) as listed above. VA's Secretary has determined that a presumption of service connection based on exposure to herbicides used in the Republic of Vietnam during the Vietnam era is not warranted for any condition for which the Secretary has not specifically determined a presumption of service connection is warranted. 72 Fed. Reg. 112 (2007). The Secretary has not determined a presumption of service connection is warranted for pharyngeal cancer or cancer of the tongue. As reported in the Federal Register, VA has specifically considered oral, pharyngeal, and squamous cell skin cancers and found the credible evidence is against an association between herbicide exposure and such cancers. As the Veteran's diagnosed disability is not among the diseases recognized under 38 C.F.R. § 3.309(e), as diseases associated with exposure to certain herbicide agents, presumptive service connection on the basis of herbicide exposure is not warranted. The Federal Circuit has held that when a claimed disorder is not included as a presumptive disorder direct service connection may nevertheless be established by evidence demonstrating that the disease was in fact "incurred" during service. See Combee v. Brown, 34 F.3d 1039, 1042 (Fed. Cir. 1994). It is the policy of VA to administer the law under a broad interpretation, consistent with the facts in each case, with all reasonable doubt to be resolved in favor of the claimant. 38 U.S.C.A. § 5107; 38 C.F.R. § 3.102. With respect to in-service incurrence, the Veteran's service treatment records (STRs) are negative for complaints of, or treatment for, cancer. The only complaints of, or treatment for, the Veteran's neck area are May 1965 STRs which reflect that the Veteran had a temperature of 101 degrees, soft tissue swelling on the right side of the neck and bad right upper molar. Lab results reflect a white blood cell count of 9,250. STRs dated the next day, reflect he had a temperature of 101.2 degrees, his white blood cell count was 9,400, his neutrophiles were 66 percent, and his lymphocytes were 26 percent. The report of medical examination for separation purposes, dated in January 1966, reflects normal findings as to the condition of the Veteran's mouth, throat, head, and neck. The accompanying report of medical history reflects that the Veteran had his tonsils removed at age 10. As noted above, the evidence of record reflects that the Veteran was first diagnosed with cancer in 1996, 30 years after separation from service. The Board finds this evidence weighs against a finding of onset in service. The Board notes that evidence of a prolonged period without medical complaint, and the amount of time that elapsed since military service, can be considered as evidence against the claim. Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000.). As there is no evidence of cancer during service, or for many years after service, the Board must consider whether there is medical evidence of a nexus between the Veteran's disability and exposure to an herbicide in service. As noted above, the claims file contains a medical opinion from Dr. C.N.B. dated in March 2007. Dr. C.N.B. opined that it is more likely than not that Agent Orange caused the Veteran's pharyngeal cancer. The basis for Dr. C.N.B.'s opinion is that the Veteran's medical records do not support a more likely etiology and the literature supports his opinion. The Board finds that this opinion lacks probative value. First, Dr. C.B.'s opinion that the medical records do not support a more likely etiology does not discuss the March 1996 correspondence from the Veteran's oncologist, Dr. M.G, which is included in the evidence of record, and specifically addresses the etiology of the Veteran's cancer. Dr. M.G. notes that the Veteran has abused smoking and alcoholism for a long time and has locally advanced squamous cell carcinoma of the hypopharynx that is related to alcoholism and smoking. Because this opinion is by an oncologist, the Board finds it to be highly probative of the etiology of the Veteran's cancer. Second, Dr. C.N.B. notes that the literature supports his opinion that the Veteran's pharyngeal cancer is causally related to Agent Orange exposure. The literature referenced by Dr. C.N.B. is Table 6-10, Selected Epidemiologic Studies- Oral, Nasal, and Pharyngeal Cancer, Veterans and Agent Orange, Update 2004, Committee to Review the Health Effects in Vietnam Veterans of Exposure to Herbicides (Fifth Biennial Update), Institute of Medicine, Washington D.C., The National Academies Press (2005). While Dr. C.N.B.'s report contains the table upon which his opinion is based; the report does not reference the table's corresponding "Synthesis" and "Conclusion". The Syntheses states: "[s]tudies from previous Updates have not shown an association between oral, nasal, and pharyngeal cancers and the compounds of interest. The study by Akhtar et al. (2004) reviewed here also showed no increased risk of cancer of the buccal cavity. The committee affirms that there is inadequate or insufficient evidence of an association." Id. at 230. The Conclusion states: "On the basis of its evaluation of the epidemiologic evidence reviewed here and in previous Veterans and Agent Orange reports, the committee concludes that there is still inadequate or insufficient evidence to determine an association between exposure to the compounds of interest and oral, nasal, and pharyngeal cancers." Therefore, the literature cited by Dr. C.N.B. does not support his opinion. Moreover, in the Update 2006, the committee reaffirmed its position that there was insufficient or inadequate information to determine whether there is an association between the compounds of interest and oral, nasal, and pharyngeal cancers. See Veterans and Agent Orange, Update 2006, Committee to Review the Health Effects in Vietnam Veterans of Exposure to Herbicides (Sixth Biennial Update), Institute of Medicine, Washington D.C., The National Academies Press (2007) at page 267. To summarize, Dr. C.B.'s opinion lacks probative value because his rationale does not consider all the evidence of record and conflicts with the literature he cites. Sepsis, Liver Failure, and Pneumonia Finally, the Board will consider whether the other conditions listed on the death certificate are causally related to military service. The Veteran's STRs are negative for any complaint of, or treatment for, sepsis, liver failure, or pneumonia. The Veteran's January 1963 report of medical history reflects a notation of no trouble with lungs or liver, but a history of pain or pressure in the chest. The examiner's "summary and elaboration" reflects no significant abnormalities with regards to this reported history. The Veteran's January 1963 report of medical examination upon enlistment reflects that upon clinical evaluation, he was noted to have normal lungs, and abdomen and viscera. The Veteran's report of medical history, dated in January 1965, but signed in January 1966, and completed in conjunction with a January 1966 medical examination, reflects no complaints of lung or liver trouble. The January 1966 report of medical examination upon separation reflects that, upon clinical evaluation, the Veteran was noted to have normal lungs, and abdomen and viscera. The certificate of death lists the approximate interval between the onset of sepsis and the Veteran's death as 10 hours. The earliest evidence of record of any pneumonia is an April 1985 private medical record which reflects that the Veteran had bilateral pneumonia; this was 19 years after the Veteran's separation from service, and thirteen years prior to his death. There is no evidence of record that the Veteran's pneumonia was related to service. The earliest evidence of record of a liver problem is a November 1980 private medical report which reflects that the Veteran had hepatomegaly; this was more than 14 years after the Veteran's separation from service. The examiner noted that the hepatomegaly was "possibly on the basis of uncontrolled diabetes mellitus, although the patient does use alcohol somewhat excessively." Such a statement is inconclusive as to the etiology of the Veteran's hepatomegaly, as such it is not probative. As noted above, medical evidence that is speculative, general or inconclusive cannot be used to support a claim. See Obert, supra. An April 1985 private medical report reflects that the Veteran has a history of liver disease from chronic alcohol ingestion. An August 1985 private medical report reflects that the Veteran is an alcoholic with liver disease. A December 1985 private medical report reflects that the Veteran "apparently has hepatomegaly, probably secondary to his chronic alcoholism." Based on the foregoing, the Board finds that the competent medical evidence of record does not reflect that the Veteran's sepsis, pneumonia, or liver failure was causally related to active service, to include as secondary to diabetes mellitus. Conclusion The competent credible clinical evidence of record fails to establish that the Veteran's service-connected diabetes mellitus was the principal or a contributory cause of the Veteran's death. Moreover, while the Veteran's service in Vietnam allows for a presumption of herbicide exposure in the present case, cancer of the pharynx or tongue is not among the diseases listed under 38 C.F.R. § 3.309(e), thus precluding a grant of presumptive service connection as due to herbicide exposure. The evidence of record fails to demonstrate that the Veteran's cancer was causally related to active service. Moreover, there is no competent medical evidence of record that the Veteran's sepsis, liver failure, or pneumonia was causally related to military service, to include as secondary to diabetes mellitus. For the above noted reasons, the appellant's claim of entitlement to service connection for the cause of the Veteran's death must be denied. As the preponderance of the evidence is against the claim, the benefit of the doubt rule is not applicable. See 38 U.S.C.A. § 5107(b); Gilbert v. Derwinski, 1 Vet. App. 49, 54-56 (1990). The appellant may sincerely believe that the Veteran's service-connected diabetes was the cause of the Veteran's death, and that his cancer was causally related to active service, to include exposure to Agent Orange. However, as a lay person she is not capable of opining on matters requiring medical knowledge or expertise. Espiritu v. Derwinski, 2 Vet. App. 492, 494 (1992). As the preponderance of the evidence is against this claim, the benefit-of-the-doubt rule does not apply, and the claim for service connection for the cause of the Veteran's death must be denied. See 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49 (1990). ORDER Entitlement to service connection for the cause of the Veteran's death is denied. ____________________________________________ U. R.
