Hepatocellular Carcinoma Treatment and Prognosis

Purpose Radiation therapy (RT) alone can cure more than 80% of all patients with pathologic stage IA, IB, and IIA Hodgkin's disease, but some prognostic factors unfavorably affect treatment outcome. Combined-modality approaches improved results compared with RT, but the optimal extent of RT fields when combined with chemotherapy warranted additional evaluation. Patients and Methods In February 1990, we activated a prospective trial in patients with early, clinically staged Hodgkin's disease to assess efficacy and tolerability of four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by either subtotal nodal plus spleen irradiation (STNI) or involved-field radiotherapy (IFRT). Results Main patient characteristics were fairly well balanced between the two arms. Complete remission was achieved in 100% and in 97% of patients, respectively. The 12-year freedom from progression rates were 93% (95% CI, 83% to 100%) after ABVD and STNI, and 94% (95% CI, 88% to 100%) after ABVD and IFRT, whereas the figures for overall survival were 96% (95% CI, 91% to 100%) and 94% (95% CI, 89% to 100%), respectively. Apart from three patients who developed second malignancies in the STNI arm, treatment-related morbidities were mild. Conclusion Present long-term findings suggest that, after four cycles of ABVD, IFRT can achieve a worthwhile outcome. The limited size of our patient sample, however, had no adequate statistical power to test for noninferiority of IFRT versus STNI. Despite this, ABVD followed by IFRT can be considered an effective and safe modality in early Hodgkin's disease with both favorable and unfavorable presentation.
