Purpose: This study was undertaken to show the clinical results of combined radiotherapy and hyperthermia in primary hepatoma
Materials and Methods: Between December 1989 and March 1993, 50 patients with hepatomas were treated by combined radiotherapy and hyperthermia. Among them, we analyzed retrospectively 33 patients who received the complete course of treatment. The ages of the patients ranged from 36 to 75(mean age: 55.5 years). Twenty-six patients (78.8%) were men, and 7 (21.2%) were women. According to Child뭩 classification, nine patients (27.3%) were A group, 9 (27.3%) were B group, 15 (45.4%) were C group. Radiation therapy was done by a 6 MV and 15 MV linear accelerator. Patients were treated with daily fractions of 150-180 cGy to doses of 2550 cGy ?4950 cGy (median: 3000 cGy). Local hyperthermia was done by 8 MHz RF capacitive heating device (Cancermia. Green Cross Co., Korea), 50-60 min/session, 1-2 sessions/wk, and 8.5 sessions (median number)/patients. We analyzed the prognostic factors including age, sex, tumor type, Child뭩 classification, a-fetoprotein, liver cirrhosis, ascites, portal vein invasion, esophageal varix, number of hyperthermia, chemotherapy, total bilirubin level, Karnofsky performance status.
Results: The overall 1-year survival was 24.2%, with a mean survival of 10 months. Of 33 patients, tumor regression (PR+MR) was seen in 30.4%, no response was seen in 52.2%, 17.4% patient was progressed. In patients who had tumor regression, the overall 1-year survival was 42.1% with a mean survival of 14 months. Factors influencing the survival were sex (p=0.05), tumor type (p=0.0248), Child뭩 classification (p=0.0001), liver cirrhosis (p=0.0108), ascites (p=0.0009), and Karnofsky performance status (p=0.0028). Complications developed in 28 patients, including 18 hot pain, 5 fat necrosis, 3 transient fever, 2 nausea and vomiting.
Conclusion: In this study, the results suggests that combined radiotherapy and hyperthermia may improve the survival rate of hepatoma.
