KRAS Mutation in Small Cell Lung Carcinoma and Extrapulmonary Small Cell Cancer

KRAS Mutation in Small Cell Lung Carcinoma and Extrapulmonary Small Cell Cancer.

BACKGROUND Lung cancer is one of the most lethal cancers. It is mainly classified into 2 groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Extrapulmonary small cell carcinomas (EPSCC) are very rare. The Ras oncogene controls most of the cellular functions in the cell. Overall, 21.6% of human cancers contain a Kirsten Ras (KRAS) mutation. SCLC and EPSCC have several s...

Survival and Prognostic Factors in Small Cell Lung Cancer Patients in Turkey

Background: Small cell lung cancer (SCLC) is a highly aggressive tumor. Objective: To evaluate the survival and time to progression of patients with SCLC admitted to a chest disease center in Istanbul, Turkey. Methods: Based on the reports of a pulmonary oncology clinic, data regarding performance status (PS), clinical stage of disease, treatment, time to progression and survival of 67 patients...

Extrapulmonary small cell carcinoma of bone.

Small cell carcinoma has been reported to arise in many extrathoracic sites. However, such tumours arising from bone have not been previously described. We report what we believe is the first reported case of extrapulmonary small cell carcinoma of bone. The tumour arose from the fifth dorsal vertebra in a 60 year old woman. The patient was treated with local radiotherapy and combination chemoth...

Clinical Overview of Extrapulmonary Small Cell Carcinoma

The objective of this study was to review the natural history of extrapulmonary small cell carcinoma (EPSCC) with specific emphasis on clinical features, response to treatment and survival. The records of all patients (n=34) with EPSCC treated at Yeungnam University Medical Center and Catholic University of Daegu Medical Center between 1998 and 2005 were retrieved and reviewed. The primary site...
