Brief Summary

The purpose of the study is to identify the most promising sequence of modalities in total neoadjuvant treatment of localy advanced rectal cancer with high risk of recurrence

Conditions

Keywords

rectal cancer; total neoadjuvant therapy; induction chemotherapy; consolidation chemotherapy

Outcome Measures

Primary Outcomes (1)

• complete remission rate

  The proportion of complete responses will be defined as the sum of the proportions of pCR in operated patients and cCR in non-operated patients.

  2 weeks after completiton of TNT

Secondary Outcomes (4)

• Overall survival

  after 3 years of follow-up

• Survival without recurrence of the disease

  after 3 years of follow-up

• Disease free survival

  after 3 years of follow-up

• local control

  after 3 years of follow-up

Study Arms (2)

consolidation chemotherapy

EXPERIMENTAL

chemoradiation: intensity-modulated irradiation technique with simultaneous integrated boost to the tumor (IMRT-SIB) or with volumetric modulated arc therapy (VMAT) with simultaneous integrated boost (VMAT-SIB) to the total tumor dose of 46.2 Gy in T1-3 tumors and 48.4 Gy in T4 tumors in 22 fractions with concomitant CT with capecitabine (dosage: 825 mg / m2 / 12 h per os continuously from the first to the last day of irradiation). 6 cycles of CAPOX chemotherapy. One cycle of CAPOX CT lasts 3 weeks and consists of capecitabine 1000 mg / m2 / 12h per os for 1-14 days and oxaliplatin 130 mg / m2 intravenously in a two-hour infusion on day 1.

Other: consolidation chemotherapy

induction chemotherapy

ACTIVE COMPARATOR

4 cycles of induction CAPOX chemotherapy. One cycle of CAPOX CT lasts 3 weeks and consists of capecitabine 1000 mg / m2 / 12h per os for 1-14 days and oxaliplatin 130 mg / m2 intravenously in a two-hour infusion on day 1. Chemoradiation:intensity-modulated irradiation technique with simultaneous integrated boost to the tumor (IMRT-SIB) or with volumetric modulated arc therapy (VMAT) with simultaneous integrated boost (VMAT-SIB) to the total tumor dose of 46.2 Gy in T1-3 tumors and 48.4 Gy in T4 tumors in 22 fractions with concomitant CT with capecitabine (dosage: 825 mg / m2 / 12 h per os continuously from the first to the last day of irradiation). 2 cycles of consolidation CAPOX chemotherapy.

Other: induction chemotherapy
