Lung cancer remains the second most common cancer diagnosis, and top cancer killer, in the United States. Early diagnosis is key for patient survival, but only 16% of cases are currently caught in the early stages. The primary care provider is uniquely poised to intervene with high-risk patients through careful monitoring and screening of select patients. This article includes discussion of the usual clinical presentation of lung cancer, and reviews the role of routine screening. A brief update in treatment advances in lung cancer is also included.

Metastatic melanoma is a donor-derived malignancy that has rarely been reported in liver allograft recipients. We present a case of a transmitted donor-derived melanoma to a liver allograft recipient in whom the diagnosis was established by polymerase chain reaction-based DNA fingerprinting. A 52-year-old African-American man underwent a successful orthotropic liver transplant for alcohol-induced cirrhosis. One year after the orthotropic liver transplant, he presented at our institution with diffuse abdominal pain, and a computed tomography scan of the abdomen and chest showed innumerable masses diffusely involving the liver and multiple subcutaneous nodules in the abdominal and chest wall. A liver biopsy confirmed the diagnosis of metastatic melanoma. The origin of melanoma was traced to the donor by DNA fingerprinting of the native liver, the donor liver, and the donor gallbladder. Chemotherapy was initiated with temozolomide (75 mg/m² daily) and thalidomide (50 mg daily), to which he responded within 8 weeks with radiologic improvement in metastatic lesions. Tacrolimus was switched to sirolimus because of renal insufficiency as well as reported effectiveness against melanoma. Our patient survived for 9 months after the diagnosis of metastatic melanoma. He ultimately died of brain metastases. Donor-derived metastatic melanoma is a rare cancer with the highest transmission and mortality rates, which requires better recognition. Prompt diagnosis of donor-derived melanoma is critical and can be achieved reliably with polymerase chain reaction-based DNA analysis. Management options after diagnosis include de-escalation of immunosuppression, with or without urgent organ removal or retransplant. The roles of chemotherapy, immunotherapy, and radiotherapy require further study.

OBJECTIVESOrgan donation after cardiac death remains an available resource to meet the demand for transplant. However, concern persists that outcomes associated with donation after cardiac death liver allografts are not equivalent to those obtained with organ donation after brain death. The aim of this matched case control study was to determine if outcomes of liver transplants with donation after cardiac death donors is equivalent to outcomes with donation after brain death donors by controlling for careful donor and recipient selection, surgical technique, and preservation solution.MATERIALS AND METHODSA retrospective, matched case control study of adult liver transplant recipients at the University of Tennessee/Methodist University Hospital Transplant Institute, Memphis, Tennessee was performed. Thirty-eight donation after cardiac death recipients were matched 1:2, with 76 donation after brain death recipients by recipient age, recipient laboratory Model for End Stage Liver Disease score, and donor age to form the 2 groups. A comprehensive approach that controlled for careful donor and recipient matching, surgical technique, and preservation solution was used to minimize warm ischemia time, cold ischemia time, and ischemia-reperfusion injury.RESULTSPatient and graft survival rates were similar in both groups at 1 and 3 years (P = .444 and P = .295). There was no statistically significant difference in primary nonfunction, vascular complications, or biliary complications. In particular, there was no statistically significant difference in ischemic-type diffuse intrahepatic strictures (P = .107).CONCLUSIONSThese findings provide further evidence that excellent patient and graft survival rates expected with liver transplants using organ donation after brain death donors can be achieved with organ donation after cardiac death donors without statistically higher rates of morbidity or mortality when a comprehensive approach that controls for careful donor and recipient matching, surgical technique, and preservation solution is used.

Hepatic sarcoidosis is a rare indication for liver transplantation. Using the United Network for Organ Sharing (UNOS)/Organ Procurement and Transplantation Network (OPTN) database, we evaluated patient and graft survival after orthotopic liver transplantation for sarcoidosis between October 1987 and December 2007. We assessed the potential prognostic value of multiple demographic and clinical variables, and we also compared these patients to a case-matched group of patients with primary sclerosing cholangitis (PSC) or primary biliary cirrhosis (PBC). The 1- and 5-year survival rates for the sarcoidosis group were 78% and 61%, respectively, and these rates were significantly worse than the rates for the PSC/PBC group (P = 0.001). Disease recurrence in the liver is a rare cause of graft loss or patient death. Three deaths occurred in the sarcoidosis group because of recurrent hepatic sarcoidosis, and 1 death was a result of cardiac sarcoidosis. A univariate analysis identified an increasing donor risk index as a significant negative factor for outcomes for the sarcoidosis group [hazard ratio (HR) = 2.06, confidence interval (CI) = 1.04-4.06, P = 0.037], but this finding was not found in a multivariate analysis, in which no independent predictors were found to have a significant impact. A case-matched univariate analysis demonstrated that sarcoidosis and morbid obesity were significant negative factors for outcomes, and in a multivariate analysis, sarcoidosis continued to predict worse outcomes (HR = 2.39, CI = 1.21-4.73, P = 0.012). In conclusion, an analysis of the UNOS/OPTN database indicates that the patient and allograft survival rates for hepatic sarcoidosis are satisfactory, but they are worse in comparison with the rates for other cholestatic liver diseases.
