Abstract

PURPOSE: This study was conducted to investigate case-fatality rates and survival rates, prognostic factors of prevalent five cancers(stomach, lung, liver, cervix, colon) in a university hospital located in Taejon City.
METHODS
2,158 cancer patients who have admitted the hospital from Jan. 1, 1991 to Dec. 31, 1998 were analysed. The higher ratio of outbreak and growing were selected among the investigated cancer data for over 100 of subjects in Korean cancer patient was examined into two method. The one is medical record and the other is affirm a government office for existence or not.
RESULTS
The lung cancer was discovered for the highest fatality rate. The crude 5-year survival rate of all cancer patients was 43.9% and that in male was higher than that in female. The 5-year survival rate of stomach cancer patients were 49.7%, that treated with combined(operation and chemotherapy) were 66.2%, that with metastasis to lymph node were 48.1%, and distant metastasis were 31.9%. Lung cancer patients were 25.9%, that treated with operation were 42.7%, and that with metastasis to lymph node were 29.3%. Hepatoma patients were 25.5%, that treated with operation were 37.8%. Uterine cervix cancer patients were 74.8%, that treated with operation were 95.0%, that with metastasis to lymph node were 83.3%, and distant metastasis 74.8%. Colon cancer patients were 41.8%, that treated with operation were 50.2%, that with metastasis to lymph node were 33.4%. Prognostic factors affecting survival rate among stomach cancer patients were age, operation, operation with cancer chemotherpy, and metastais to lymph node and distant matastasis. Prognostic factors of uterine cervix cancer was age, and that of colon cancer were operation with radiotherapy, metatasis to lymph node and distant metastasis.
CONCLUSION
case-fatality rate in male were higher than that in female, and increased with age. The cancer survival rate of female is high, the high in over 40 years group, and operation is exposed in the highest survival rate, also significant difference in metastasis level.
