Summary

This study is a multicenter, open, and phase I dose increasing clinical study. Based on the UGT1A1 \* 28 and \* 6 genotypes of patients with locally advanced rectal cancer, determine the dose limiting toxicity (DLT) and maximum tolerable dose (MTD) of weekly irinotecan liposomes in concurrent chemoradiotherapy with capecitabine, investigate the tolerance of irinotecan liposome combined with capecitabine in concurrent chemoradiotherapy with locally advanced rectal cancer, and recommend the dosage for Phase II clinical study，and explore the pharmacokinetic characteristics of irinotecan liposomes combined with capecitabine.At the same time，Preliminary observe the efficacy and safety of irinotecan liposomes combined with capecitabine in chemoradiotherapy.The study plans to recruit 30 patients with advanced rectal cancer who have not received any therapy.

DRUG

irinotecan liposomes+capecitabine

Radiotherapy：IMRT DT 50Gy/25Fx. Capecitabine: 625mg/m2 bid po d1-5 qw. For patients are double sites mutant (GG+7/7 or AA+6/6 or GA+6/7)，the intial dose of Irinotecan liposomes is 25mg/m2 weekly，for four weeks。 This study stratify cases by the "3+3" rule according to UGT1A1 \* 6 and UGT1A1 \* 28 phenotypes. Three cases were enrolled in each dose group, and if there was no DLT, they were promoted to the next dose group（an increase of 5mg/m2）; If there is 1 case of DLT, 3 cases will be reenrolled in the same dose group. If there is no new occurrence of DLT, it will be promoted to the next dose group. Otherwise, the study will be terminated; If there are 2 cases of DLT, the study will be terminated, and the previous dose group will be the maximum tolerated dose (MTD).
