Evaluation of survival rates and number of patients with malignant neoplasms surviving for a long time after treatment at the National Cancer Center Hospital.
Since 1962, the National Cancer Center Hospital has been active in the medical care of cancer patients. Also, it has conducted cancer registration and collected information on cancer patients. According to the data collected, survival rates, as well as statistics tables, were calculated. The 5-yr survival rates for patients admitted to the hospital show an increasing trend for cancer in many sites. Consequently, the overall 5-yr survival rates for patients with malignant neoplasms have risen. They are 36.65% in males and 59.81% in females for patients admitted in the period from 1975 to 1980. The progress in diagnosis and treatment of cancer has brought an increase in the number of long-term survivors among cancer patients. According to the statistics of 1983, the number of patients surviving 5 yr or more after treatment at the National Cancer Center Hospital was 8,193, for 10 yr or more it was 3,717 and for 15 yr or more it was 1,412.
