Hepatitis B virus(HBV)reactivation is a serious clinical problem for HBV infected patients, and one of its possible causes is chemotherapy for malignant disease. At the onset of active hepatitis, planned chemotherapy should be discontinued and acute or fetal fulminant hepatitis must be induced in some cases. Therefore, it is desirable to prevent virus reactivation during chemotherapy in HBV-positive patients. We report a case in which adjuvant chemotherapy for a breast cancer patient was accomplished safely by using entecavir. The patient was a 48-year-old woman with breast cancer whose HBV infection had been pointed out when she was 20 years old. Breast reconstruction was performed, followed by mastectomy. Pathological findings were invasive ductal carcinoma, three positive nodes, estrogen and progesterone receptor-positive, and HER2-negative. An adjuvant chemotherapy with anthracycline followed by taxane was planned. Blood chemistry revealed the seroconversion of HBV and the quantity of HBV-DNA was 2. 8 log copies/mL. Administration of the anti-virus agent, entecavir, was started three weeks before chemotherapy. The HBV-DNA was decreased under the titer of detection and no re-increase in HBV-DNA was found during chemotherapy. Planned chemotherapy was accomplished safely without HBV reactivation.

We report the case of a 60-year-old female with liver dysfunction resulting from diffuse liver metastases, which, atypically, had originated from breast cancer. She responded remarkably well to trastuzumab monotherapy. She was referred to our hospital because of left breast cancer with multiple general lymphadenopathies. She presented with jaundice and liver dysfunction without a space-occupying lesion or a dilatation of the intrahepatic bile duct on computed tomography images. A liver biopsy was done to rule out autoimmune hepatitis, primary biliary cirrhosis, or primary sclerosing cholangitis, and histopathological examination showed adenocarcinoma in the lymph duct of the liver. Both the primary breast cancer and the liver metastases were negative for hormone receptor expression(ER-, PR-), but overexpressed HER2(HercepTest 3+). She was diagnosed as invasive ductal carcinoma(T1N3cM1, Stage IV). We started trastuzumab monotherapy, which improved her jaundice and liver dysfunction, and resulted in a decrease in lymph node size.

Paclitaxel induced mild derangement of liver functions including bilirubin, alkaline phosphatase, and AST has been infrequently noticed in clinical trials. Contrary to Paclitaxel, hepatocellular injury, hepatitis, and liver tenderness are common laboratory and clinical findings with Trastuzumab. However, hepatic failure/necrosis secondary to Paclitaxel or Trastuzumab has never been reported in literature. A 62-year-old lady, previously healthy, was treated with adjuvant therapy for left breast stage II, high grade invasive ductal carcinoma which was node negative, oestrogen receptor negative, progesterone receptor positive, and HER2 receptor positive. After modified radical mastectomy and axillary clearance, she finished four cycles of Doxorubicin/Cyclophosphamide chemotherapy and then commenced on Paclitaxel/Trastuzumab combination chemotherapy. Within twelve hours of first dose of Paclitaxel/Trastuzumab therapy, patient required hospital admission for acute onset respiratory failure. Patient died within 36 hours of therapy and autopsy was suggestive of acute hepatic necrosis without any other significant findings. Detailed investigations were not carried out as event was quick with rapid deterioration. There was no history of prior liver pathology/injury and preliminary investigations for major organ involvement were unremarkable. As per our knowledge, Paclitaxel and/or Trastuzumab induced acute hepatic necrosis has never been reported in literature before, hence difficult to predict.

While aromatase inhibitors (AIs) have been known to cause minor elevations in liver enzymes, severe hepatotoxicity is rare. To the best of our knowledge, this is the first reported case of Letrozole-induced hepatitis with autoimmune features. A 70-year-old female with estrogen positive, invasive ductal carcinoma of the breast, presented with jaundice 3 months after starting letrozole. Hepatic transaminases were markedly elevated and her ANA and anti-smooth muscle antibody was positive. Liver biopsy featured drug-induced hepatitis. After stopping letrozole, liver tests trended back to normal within 3 weeks. She scored 9 for Roussel-Uclaf Causality Assessment Method (RUCAM). Over the last 10 years, there have been reported cases of drug-induced hepatitis secondary to AIs. We anticipate that there will be more widespread use of AIs based on recommendations from the TEXT, SOFT and extended AI trials. Therefore, physicians must be aware of this rare but life-threatening complication.
