Large Cell Neuroendocrine Carcinoma of the Ovary and Its Skin Metastases: A Case Report and Review of the Literature.

Large cell neuroendocrine carcinoma in the gynaecological organs affects the uterine cervix and ovary. Large cell neuroendocrine carcinoma of the ovary is extremely rare, and prognosis is quite poor even when diagnosed at an early stage. These tumours respond poorly to standard chemotherapy regimens. The clinical observation of skin metastasis in patients with epithelial ovarian cancer is relatively uncommon, occurring in only 3.5% of patients. These lesions are observed mostly in skin of the abdominal wall adjacent to the primary ovarian tumours. Metastatic skin lesions on extremities are much more rare; it is reported that only 12% of epithelial ovarian carcinoma skin metastases occur on the limbs. Skin metastasis due to large cell neuroendocrine carcinoma of the ovary has not been previously reported. We report the case of a large cell neuroendocrine tumour of the ovary with skin metastases on extremities appearing two months after surgery in a 68-year old woman.

Gemcitabine alone versus combination of gemcitabine and cisplatin for the treatment of patients with locally advanced and/or metastatic pancreatic carcinoma: a retrospective analysis of multicenter study.

The majority of patients with pancreatic cancer is of advanced disease. Several randomized Phase II and III trials suggest that the combination of gemcitabine and cisplatin (GemCis) response rates were higher than Gemcitabine (Gem) alone, however the trials were not enough powered to indicate a statistically significant prolongation of survival in patients with advanced pancreatic adenocarcinoma. The aim of this retrospective multicenter study is to evaluated the efficiency of Gem alone versus GemCis in patients with locally advanced and/or metastatic pancreatic adenocarcinoma .A total of 406 patients, from fourteen centers were evaluated retrospectively. All patients received Gem or GemCis as first-line treatment between September 2005 to March 2011. Primary end of this study were to evaluate the toxicity, clinical response rate, progression-free survival (PFS) and overall survival (OS) between the arms. There were 156 patients (M: 98, F: 58) in Gem arm and 250 patients (M: 175, F: 75) in the combination arm. Gemcitabin arm patients older than the combination arm ( median 63 vs 57.5, p=0.001). In patients with the combination arm had a higher dose reduction (25.2% vs 11.3%, p=0.001) and dose delay (34% vs 16.8%, p=0.001). Among patients with the combination and Gemcitabin arm gender, diabetes mellitus, performance status, cholestasis, grade, stage did not have a statistically difference (p>0.05). Clinical response rate to the combination arm was higher than the Gem arm (69.0% vs 49.7%, p=0.001). PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance (8.9 vs 6.0, p=0.08). OS was not significantly superior in the GemCis arm (12.0 vs 10.2, p>0.05). Grade III-IV hematologic and nonhematologic toxicity were higher in the combination arm. PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance. OS was not significantly superior in the GemCis arm.

Gemcitabine plus infusional 5-fluorouracil and high dose leucovorin in advanced stage pancreatic cancer.

PURPOSE: Advanced pancreatic cancer (APC) has a poor prognosis and chemotherapy remains the primary treatment modality. Gemcitabine (GEM) and 5-fluorouracil (5-FU) are the most active drugs in the treatment of pancreatic cancer. This study evaluated the efficacy and tolerability of the combination of these agents in APC. METHODS: Forty-four patients with APC were treated with GEM and infusional 5-FU with high dose leucovorin (LV5FU2) (GEMFUFOL regimen). RESULTS: A total of 240 chemotherapy cycles were administered. The overall response rate was 27.2%, and all responses were partial. Furthermore, disease stabilization was observed in 12 patients (27.2%). Median survival time and one-year survival rate were 9 months and 36.4%, respectively. The overall grade 3 or 4 adverse events were very low and mostly hematological. CONCLUSION: GEMFUFOL is still an active regimen for the treatment of APC and has an acceptable toxicity.

Hypoglycemia induced by long-acting somatostatin analogues in a patient with nonfunctional neuroendocrine tumor.

Somatostatin and its long-acting analogues are effective in symptom control in patients with functional neuroendocrine tumors; they are also able to control tumor growth. Somatostatin analogues are safe and generally well tolerated. In some cases they may cause serious complications. Somatostatin analogues are potent inhibitors of growth hormone (GH) and glucagon secretion. They cause impairment of hepatic glucose output and delay in intestinal absorption of carbohydrates. Patients with huge tumor mass and multiple liver metastases have increased risk of tumor-induced hypoglycemia. In these patients, long-acting octreotide may trigger serious hypoglycemia. The patients whose glucose control is dependent on counter-regulatory hormones should be monitored for the possibility of hypoglycemia. Herein, we present a patient with severe and prolonged hypoglycemia after long-acting octreotide treatment.

Synchronous appearance of male breast cancer and pancreatic cancer 15 years after the diagnosis of testicular cancer--report of a case.

The frequency of new neoplastic diseases among patients cured of testicular cancer is higher than in normal population. For these patients, synchronous occurrence of multiple neoplasms is not common. Also, less than 1% of all cases of breast cancer occur in males. We present herein a case having both breast and concurrent pancreatic cancer after being effectively treated for testicular cancer. To the best of our knowledge, this is the first case of synchronous breast and pancreatic cancer in a male patient following testicular cancer. Second cancer is the most severe long-term complication of chemotherapy or radiotherapy for patients with testicular cancer and the possibility of multiple cancers has to be taken into consideration when multiple lesions are present.
