Hepatocellular carcinoma associated other primaries: common types and prognosis

Hepatocellular carcinoma (HCC) is the commonest malignancy in Egypt secondary to endemic hepatitis virus. Dual malignancy with HCC is infrequently reported. We herein retrospectively collected data of HCC patients with another primary tumor from a tertiary cancer center. Fifteen patients were enrolled in this case series, epidemiologic data, type of second malignancy, time interval between both tumors, treatment applied, and pattern of recurrence and survival are displayed. Third of the tumors were synchronous, while in the rest HCC was mostly the second malignancy. Breast cancer was the commonest encountered other primary. None of the second malignancies recurred after treatment except for prostate cancer which was not treated radically. The median overall survival of the patients was shorter than previously published series about 29 months. In conclusion, dual malignancy with HCC had more complicated treatment panels; however, they are not necessarily carrying a worse prognosis. HCC tumor outcome remains the main predictor of survival.
