Arm Type

Experimental

Active Comparator

Arm Label

Prophylactic Entecavir

Preemptive Entecavir

Arm Description

use of entecavir in the dose of 0.5mg p.o. every day from the initiation of chemotherapy till 6 months after the end of chemotherapy.

use of entecavir in the dose of 0.5mg p.o. every day from the time that the DNA copies of hepatitis B virus are more than 100 IU/ml till 6 months after the end of chemotherapy.

Outcomes

Primary Outcome Measures

Incidence of hepatitis B virus associated hepatitis

Hepatitis is defined as a 3-fold or greater increase in the serum ALT level that exceeded the reference range (>58U/L) or an absolute increase in the level of ALT of greater than 100 U/L compared with the baseline level

Secondary Outcome Measures

The incidence of hepatitis B virus reactivation

Reactivation of HBV is defined as a 10-fold or greater increase in the HBV DNA level or an absolute increase of 10^5 copies/mL or greater compared with the baseline value.

Interruption of chemotherapy due to hepatitis

Chemotherapy disruption is defined as either premature termination or a delay of at least 7 days between chemotherapy cycles.

5. Study Description

Brief Summary

There has been no report on whether the patients with gastric cancer who are also inactive Hepatitis B carriers should receive prophylactic use or preemptive Use of an Anti-viral Drug Entecavir. This open, randomized controlled clinical trial aims to compare the impact of the prophylactic use or preemptive use of an anti-viral drug Entecavir on the outcomes of patients with gastric cancer who are also inactive hepatitis B carriers during chemotherapy and the subsequent follow-ups.

Detailed Description

Patients with gastric cancer who are also inactive hepatitis B carriers are enrolled and randomized into two groups as following. Patients in experimental group are treated with entecavir prophylactically in the dose of 0.5mg p.o. every day from the initiation of chemotherapy till 6 months after the end of chemotherapy.Patients in active comparator group are only treated with entecavir in the dose of 0.5mg p.o. every day from the time that the DNA copies of hepatitis B virus are more than 100 IU/ml till 6 months after the end of chemotherapy.
