BACKGROUND: Patients with unresectable recurrent rectal cancer that progresses after systemic chemotherapy and radiotherapy may be candidates for palliation with hypoxic pelvic perfusion (HPP). The aim of this observational retrospective study was to evaluate if a multimodality treatment including HPP and targeted-therapy may be useful to prolong clinical responses and survival of these patients.
METHODS: Thirty-seven patients with unresectable recurrent rectal cancer in progression after standard treatments underwent repeated HPP with mitomycin C (25 mg/m2) and cisplatin (70 mg/m2). Twenty patients, exhibiting epidermal growth factor receptor (EGFR) overexpression, also received cetuximab targeted-therapy, following the ultimate HPP treatment.
RESULTS: Following initial HPP treatment, median progression-free survival was 7 months (range: 5-19 months), median time-to-death or termination of follow-up was 13 months (range: 9-18 months), one-year survival-rate was 59.45%, two-year survival rate was 10.81%, and three-year survival rate was 2.7%. Survival was significantly influenced by cetuximab targeted-therapy post-HPP and the presence of additional metastatic sites (P<0.03).
CONCLUSIONS: Repeated HPP treatments with mitomycin C plus cisplatin, followed by cetuximab targeted-therapy, may represent a safe and efficacious palliative therapy in patients with unresectable recurrent rectal cancer, in progression following standard systemic chemo- and radio-therapy, and thus warrants confirmation in a larger phase III study.
