Preoperative radiotherapy and local excision of rectal cancer: Long-term results of a randomised study.

Background And Purpose: It is uncertain whether local control is acceptable after preoperative radiotherapy and local excision (LE). An optimal preoperative dose/fractionation schedule has not yet been established.

Material And Methods: In a phase III study, patients with cT1-2N0M0 or borderline cT2/T3N0M0 < 4 cm rectal adenocarcinomas were randomised to receive either 5 × 5 Gy plus 1 × 4 Gy boost or chemoradiation: 50.

Does the addition of oxaliplatin to preoperative chemoradiation benefit cT4 or fixed cT3 rectal cancer treatment? A subgroup analysis from a prospective study.

Background: Whether there is any benefit derived from adding oxaliplatin to fluoropyrimidine-based preoperative chemoradiation is currently unknown in cases of advanced cT3 or cT4 tumours. Our aim was to evaluate this issue by analysing a randomized trial, which compared two schedules of preoperative treatment (chemoradiation vs. 5 × 5 Gy with 3 cycles of consolidation chemotherapy) for cT4 or fixed cT3 rectal cancer.

Long-course oxaliplatin-based preoperative chemoradiation versus 5 × 5 Gy and consolidation chemotherapy for cT4 or fixed cT3 rectal cancer: results of a randomized phase III study.

Background: Improvements in local control are required when using preoperative chemoradiation for cT4 or advanced cT3 rectal cancer. There is therefore a need to explore more effective schedules.

Patients And Methods: Patients with fixed cT3 or cT4 cancer were randomized either to 5 × 5 Gy and three cycles of FOLFOX4 (group A) or to 50.

Preoperative radiotherapy and local excision of rectal cancer with immediate radical re-operation for poor responders: a prospective multicentre study.

Purpose: To assess local control after preoperative radiation and local excision and to determine an optimal radiotherapy regimen.

Methods: Eighty-nine patients with G1-2 rectal adenocarcinoma <3-4 cm; unfavourable cT1N0 (23.6%), cT2N0 (62.

Preoperative radiotherapy and local excision of rectal cancer with immediate radical re-operation for poor responders.

Background And Purpose: To report an early analysis of prospective study exploring preoperative radiotherapy and local excision in rectal cancer.

Materials And Methods: Mucosa at tumour edges was tattooed. Patients with cT1-3N0 tumour <3-4 cm were treated with either 5x5Gy+4Gy boost (N=31) or chemoradiation (50.
