Hypofractionated Radiotherapy Combined With NALIRIF, PD-1 Antibody in Locally Recurrent Rectal Cancer(NOVELTY-R)

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.

Intraoperative Electron Radiotherapy in Rectal Cancer - A Feasibility Trial

Single centre double-blinded three-arm randomised controlled trial of extended margin surgery + IOERT at standard dose (10 Gy) versus extended margin surgery + IOERT at higher dose (15 Gy) versus extended margin surgery alone in a 1:1:1 ratio in patients with Locally Advanced Rectal Cancer (LARC) or Locally Recurrent Rectal Cancer (LRRC).

Hypofractionated Radiotherapy Plus Immunotherapy Versus Conventional Radiotherapy in Locally Recurrent Rectal Cancer

TORCH-R2 is a prospective, multicenter, randomized, phase II clinical trial. Patients aged 18 years or older with pelvic recurrence rectal cancer without synchronous distant metastases or recent chemo- and/or radiotherapy treatment, Eastern Cooperative Oncology Group performance status of 0-1will be enrolled . Patients will be randomized to receive either hypofractionated radiotherapy (25-40Gy/5Fx irradiation or 15-30Gy/5Fx reirradiation), 18 weeks sintilimab and investigator's choice of first-line chemotherapy +/- target therapy (experimental arm), or conventional radiotherapy (50Gy/25Fx irradiation or 39Gy/30Fx bid reirradiation) and chemotherapy +/- target therapy (control arm). Patiens will be restaged and followed by multidisciplinary team (MDT) for decision: radical surgery, sustained systerm+/- local treatment of non resection. The primary endpoint was progression-free survival. Secondary endpoints were objective response rate (ORR), complete response rate, R0 resection rate, duration of response (DOR), overall survival (OS), and safety and tolerability of the treatment.

Preoperative (Chemo)Radiotherapy for Locally Recurrent Rectal Cancer

Through an observational study, the efficacy and safety of preoperative chemoradiotherapy followed by surgery in patients with recurrent rectal cancer were assessed. The primary population included patients with (potentially) resectable locally recurrent rectal cancer, excluding those with distant metastases. The study design was a prospective, open-label, single-arm observational study. The primary endpoint was the pCR (pathological complete response) rate, while secondary endpoints included R0 resection rate, local recurrence-free survival, overall survival, and safety.
