Summary
This is an open-label, single arm, phase 2 study. The study is to evaluate the activity of combination therapy of hypofractionated radiotherapy, Irinotecan Hydrochloride Liposome plus 5-FU and leucovorin (NALIRIF), Anti-PD1 and target therapy in patients with locally recurrent rectal cancer (LRRC). The inclusion LRRC patients were failed to oxaliplatin treatment in prior chemotherapy or chemoradiotherapy due to toxicity or progression. Patients will receive 25-40Gy/5Fx irradiation or 15-30Gy/5Fx reirradiation for pelvic recurrence, 25-50Gy/5Fx irradiation for all metastasis sites, and 8 cycles of NALIRIF + anti-PD1 + target therapy, followed by multidisciplinary team (MDT) for decision: radical surgery, sustained system +/- local treatment of non resection. The primary endpoint was local objective response rate. Secondary endpoints were extrapelvic objective response rate, complete response rate, R0 resection rate, duration of response, progression-free survival, overall survival, and safety and tolerability of the treatment.
