Abstract

BACKGROUND
A clinical study was carried out on 153 new cases with small cell lung cancer registered at Presbyterian Medical Center, Chonju during the 7 years from 1986 to 1992. They were analyzed by sex and age distribution, symptoms and signs, classification of stage and site and its treatments. Especially, an effort was made to compare the overall survival time between limited stage and extensive stage.
METHODS
Among 806 lung cancer patients diagnosed by biopsy or cytologic evaluation for the 7 years, 153 patients was shown small cell lung cancer. These 153 cases was analyzed retrospectively through patient's records, letters or telephones.
RESULTS
The results of evaluation of small cell lung cancer are as follows. Over 85 percent of the small cell lung cancer patients were over 50 years of age and prominent clinical features were cough(86.3%), sputum(75.8%) and dyspnea(54.9%). One hundred and five patients (68.7%) was staged to have limited stage. Mean survival time of the chemotherapy and chemoradiotherapy in limited stage has significant difference and its survivals are 5.3 months and 15.0 months. Patients whose disease was staged as limited, regardless of whether or not chemotherapy was administered, had a median survival time of 10.9 months, compared with 4.8 months for those with extensive stage.
CONCLUSION
Lung cancer is one of the malignant diseases tend to increase gradually in Korea and proven to be the most common cancer next to the gastric cancer among various cancers in males found at the Presbyterian Medical Center in the past seven years. This report is a retrospective view of the clinical therapeutic results of the small cell lung cancer patients. Especially at the limited stage, the combined therapy revealed higher survival rate than the chemotherapy alone. For a more accurate evaluation, a prospective view, without any bias, of patients selected at random is needed.
