Total Neoadjuvant Therapy for Locally Advanced Rectal Cancer

Phase 2
Conditions
Rectal Cancer
Interventions
Drug: FOLFOXIRI
Registration Number
NCT02942563
Lead Sponsor
RenJi Hospital
Brief Summary

The concurrent neoadjuvant chemoradiation therapy is standard care for local advanced rectal cancer (LARC), however, this regimen may induce sorts of adverse events, and part of them even more severer. A number of pilot studies had shown high rate of complete resection after neoadjuvant chemotherapy alone, but the results did not increase the ratio of pathological complete response (pCR), which was associated with overall survival (OS). Here, the investigators adopt the three active cytotoxic agents (Fluorouracil, Oxaliplatin, Irinotecan, FOLFOXIRI) as the neoadjuvant chemotherapy regimen to replace the concurrent chemoradiation and to improve the ratio of pCR further.

Detailed Description

This is a multicenter, phase II trial to assess the efficacy/safety of triplet regimen (FOLFOXIRI) for patients with LARC. After 4 cycles of FOLFOXIRI and 2 weeks later, the patients will be evaluated by senior radiologist, oncologist and surgeon through pelvic MRI, CT and Positron Emission Computed Tomography (PET-CT). The patients will go to surgery (TME) if the tumor response is good enough to have complete resection under the decision of MDT,otherwise, the patients will receive pelvic radiotherapy(45Grey/25Fraction and 5.4Grey/3Fraction boost to the tumor bed) combined with capecitabine(625mg/M\^2, bid po, d1-5, qw), and additional four cycles of modified FOLFOX6 (mFOLFOX6) or Oxaliplatin 135mg/m²plus Capecitabine 1.0/m² bid po(XELOX) of each 3 weeks cycle for 2 cycles chemotherapy before TME. All patients will receive 6-8 cycles of mFOLFOX6 or 4-5 cycles XELOX as adjuvant chemotherapy after TME.
