Hi, Approximately 60-70% of patients with small cell lung cancer have clinically disseminated or extensive disease at presentation. Extensive-stage is incurable. When given combination chemotherapy, patients with extensive-stage disease have a complete response rate of more than 20%. For individuals with limited-stage disease that is treated with combination chemotherapy plus chest radiation, a complete response rate of 80%. Indicators of poor prognosis include relapsed disease, weight loss of greater than 10% of baseline body weight, and poor performance status. For all patients with lung CA, activity should be encouraged and a dietary consultation should be obtained.
