Abstract:
The reactivation of the hepatitis B virus(HBV)induced by chemotherapy can cause fulminant hepatitis, followed by death. In Japan, the Ministry of Health, Labor and Welfare released the guideline on the prevention of chemotherapy- induced reactivation of HBV in 2009. The NCGM's pharmacy department conducted a study on the HBV screening rate and the guideline compliance rate in patients undergoing chemotherapy who met the criteria for monthly HBV DNA monitoring during chemotherapy and 12 months after. We also conducted a study on the influence on the guideline compliance rate with inquiries by pharmacists. The HBV screening rate was 100%(68/68 cases), and there were inquiries in 10.3% (7/68 cases). This suggests that inquiries contributed to the improvement in the HBV screening rate. However, the guideline compliance rate in high-risk cases was 75.0%(12/16 cases). It is necessary to raise awareness in physicians and patients on the management of HBV reactivation and to establish a follow-up system for HBV DNA monitoring.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
