Clinical study of cisplatin hyperthermic intraperitoneal perfusion chemotherapy in combination with docetaxel, 5-flourouracil and leucovorin intravenous chemotherapy for the treatment of advanced-stage gastric carcinoma.

BACKGROUND/AIMS: The purpose of this study is to observe and compare the preliminary efficacy and side effects of docetaxel, 5-fluorouracil and leucovorin intravenous chemotherapy in combination with cisplatin hyperthermic intraperitoneal perfusion chemotherapy for the treatment of advanced gastric cancer.

METHODOLOGY

Retrospectively analyzed 101 patients with advanced gastric cancer receiving docetaxel, 5-fluorouracil, leucovorin and cisplatin intravenous chemotherapy or intravenous administration of docetaxel, 5-fluorouracil and leucovorin combined with cisplatin hyperthermic intraperitoneal perfusion chemotherapy, 49 patients in intravenous chemotherapy (VC) group, 52 patients in hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) group.

RESULTS

The response rate was 44.9% (22/49) in VC group and 65.4% (34/52) in HIPEC group, among which there was 1 case of CR, and the difference was statistically significant (p= 0.038). For CBR evaluation, the effective rate was 65.3% (32/49) in VC group and 82.7% (43/52) in HIPEC group, and the difference was statistically significant (p= 0.0458). The median progress free survival time (PFS) was 3.4 months in VC group and 4.6 months in HIPEC group, the difference was statistically significant (p= 0.045). The median overall survival time (OS) was 6.7 months in VC group and 7.5 months in HIPEC group, the difference was not statistically significant (p= 0.201). The main side effects in two groups were well tolerated, and there was no statistically significant difference.

CONCLUSIONS

The short-term efficacy and PFS of HIPEC plus intravenous chemotherapy were better than single intravenous chemotherapy, and there was no significant improvement in OS, the side effects were similar in two groups with good tolerability.
