Background:
Almost all elderly patients with peritoneal metastatic gastric cancer (PGC) are unlikely to tolerate cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) and adjuvant chemotherapy. However, determining how to optimize the treatment strategy for such patients has always been a clinical problem. Both HIPEC and palliative adjuvant chemotherapy can benefit patients with PGC. Therefore, optimizing HIPEC and chemotherapy regimens has potential clinical value in reducing side effects, and improving treatment tolerance and clinical effectiveness.
Aim:
To explore the effect of HIPEC containing elemene, which is an anti-cancer component extracted in traditional Chinese herbal medicine, combined with reduced capecitabine and oxaliplatin (CapeOx) chemotherapy regimens, in elderly patients with PGC.
Methods:
In the present study, 39 of 52 elderly PGC patients were included and assigned to different HIPEC treatment groups [lobaplatin group (group L) and mixed group (group M)] for analysis. Lobaplatin was used for all three HIPECs in group L. In group M, lobaplatin was used in the middle of the three HIPECs, and elemene was used for the first and third HIPEC. After HIPEC, patients received CapeOx chemotherapy. The incidence of complications (abdominal infection, lung infection, and urinary tract infection), myelosuppression, immune function (CD4/CD8 ratio), average length of hospital stay, and prognosis were compared between these two groups.
Results:
There was no significant difference in the incidence of complications between the two groups during hospitalization (P > 0.05). Compared to patients in group M, patients in group L exhibited severe myelosuppression (P = 0.027) and increased length of hospital stay (P = 0.045). However, no overall survival benefit was observed in group M. Furthermore, the immune function of patients in group M was less affected (P < 0.001), when compared to that of patients in group L. The multivariate analysis suggested that the cycles of chemotherapy after perfusion significantly affected the prognosis of patients in both groups.
Conclusion:
Compared to the lobaplatin-based HIPEC regimen, the administration of elemene reduced the myelosuppression incidence in elderly PGC patients. The present study sheds light on the implementation of this therapeutic strategy for this set of patients.
