Background
Hepatitis C virus infection (HCV) is a major health problem in Egypt. Breast cancer is the most common cancer among Egyptian women. Considering that both diseases are frequent in the Egyptian population, it is likely that many women are affected by both.
Purpose
To evaluate patient safety and applicability of chemotherapy in chronic hepatitis C virus-infected patients with breast cancer.
Subjects and methods
We performed retrospective survey of 58 Egyptian patients diagnosed with both diseases. We retrospectively investigated the baseline patient and tumor characteristics, the toxicities of chemotherapy, and the changes in HCV viral load before and after chemotherapy, in addition to treatment received for HCV infection.
Results
Forty-four (75.9%) out of the 58 patients received chemotherapy with or without trastuzumab and one patient received lapatinib. We reported 2 patients who had HCV viral reactivation. Treatment with trastuzumab or Lapatinib was not associated with elevation in liver enzymes or change in HCV RNA viral load. Treatment discontinuation occurred in 31.8% (14/44) of patients due to complications. Dose reductions and/or dose delays were common (27.2%). Elevated liver enzymes were developed in 20 out of 44 (45.5%) patients who received chemotherapy. Three patients received antiviral treatment concomitant with chemotherapy with no significant complications.
Conclusions
Greater attention should be paid to the possibility of complications including HCV reactivation, fulminant hepatitis, and interrupted chemotherapy treatments in breast cancer patients with chronic HCV infection receiving immunosuppressive drugs. Close monitoring of patients with breast cancer and HCV infection should be done
