Abstract:

Objective

Retrospective analysis to investigate the short-term curative effect and safety of pseudomonas aeruginosa-mannosesensitive hemagglutinin (PA-MSHA) and cisplatin in the treatment of malignant ascites of colorectal cancer.

Methods

A retrospective analysis was made on 49 patients with colorectal cancer whose abdominal B-mode ultrasonography proved to be moderate to large amount of peritoneal effusion and malignant ascites by cytological examination in the Fourth Hospital of Hebei Medical University. There are 31 patients in the PA-MSHA group and 18 patients in the cisplatin group. PA-MSHA: Intraperitoneally inject PA-MSHA 10 mL×10 in the first, third, and fifth day, 7 days a cycle, 2 cycles in total. Cisplatin group: Intraperitoneally inject cisplatin 50 mg/m2 in the first day, 7 days a cycle, 2 cycles in total. The two groups were given mFOLFOX6 chemotherapy at the same time. The short-term efficacy was evaluated according to the WHO (1981) treatment criteria for malignant ascites. The quality of life was evaluated according to the Karnofsky score, and the adverse reactions during the treatment were evaluated.

Results

Among 31 cases in the PA-MSHA group, 19 cases were effective. Five cases in the cisplatin group were effective among 18 cases (χ2=5.118, P=0.024). The quality of life (QOL) of 22 patients were obviously improved in the PA-MSHA group, while 7 cases in the cisplatin group (χ2=6.586, P=0.01). The rate of fever is 38.71% in the PA-MSHA group and 11.11% (χ2=4.25, P=0.039) in the cisplatin group. There was 1 case (3.23%) of abdominal pain in the PA-MSHA group, six cases (33.33%)in the cisplatin group (χ2=8.43, P=0.004). There was no abdominal infection in the PA-MSHA group, and 2 cases (11.11%) of abdominal infection in the cisplatin group (χ2=3.591, P=0.058).

Conclusion

Intraperitoneal infusion of PA-MSHA is a safe and effective treatment for malignant ascites of colorectal cancer. It can achieve good short-term effect and improve the quality of life of patients. The effective rate in the PA-MSHA group is significantly higher than that in the cisplatin group.
