[Examination of second-line therapies following administration of low-dose TS-1+CDDP for highly-advanced gastric cancer].
Sixteen patients with highly-advanced gastric cancer were administered low-dose TS-1 and CDDP as a first-line treatment, followed by either paclitaxel or CPT-11/CDDP as a second-line treatment. The results of the 2 second-line treatments are reported herein. Overall response rate for the first-line treatment was 55.6%. For the second-line treatments, responses were noted in both the paclitaxel group and the CPT-11/CDDP group. Overall MST was 16.3 months and 1-year survival was 60%. The paclitaxel group, however, showed significantly better prognoses than the CPT-11/CDDP group. Adverse reactions to the first-line treatment were grade 3 leukopenia in 1 patient, with no other reactions over grade 2 observed. No adverse reaction greater than grade 2 was noted during administration of the second-line treatments. These results appear to present ample data that a first-line treatment of low-dose TS-1/CDDP followed by a second-line treatment of paclitaxel at 1/week in the outpatient setting yields improved prognoses and minimal adverse reactions.
