This phase III trial included patients with low rectal adenocarcinoma which initially required APR, with a mean clinical distance between the tumor inferior pole and the levator ani of 0.5 cm. Patients were randomly assigned to receive high-dose radiation (45 + 18 Gy) or radiochemotherapy (45 Gy + 5FU continuous infusion). The surgical decision was based on the tumor status at surgery. All surgeons used a homogenous SSR technique such as intersphincteric resection. The primary endpoint was the SSR rate.

Condition Intervention Phase
Rectal Cancer Radiation: High-Dose radiotherapy Radiation: Chemo-radiotherapy Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Trial Comparing Two Neoadjuvant Treatments in Patients With Ultra-low Rectal Cancer: High-dose Radiotherapy Versus Radio-chemotherapy

Further study details as provided by Institut du Cancer de Montpellier - Val d'Aurelle:

Primary Outcome Measures:
  • Sphincter preservation rate [ Time Frame: surgery ]

Secondary Outcome Measures:
  • Tumor response according to rectal endo-echography [ Time Frame: prior to surgery ]
  • operative mortality and morbidity [ Time Frame: after surgery ]
  • anatomopathology margins (lateral and inferior) [ Time Frame: after surgery ]
  • Functional results (stoma closure, continence, manometry) [ Time Frame: 2 years ]
  • Local recurrence [ Time Frame: 3 years ]
  • Disease-free survival [ Time Frame: 3 years ]
  • Overall Survival [ Time Frame: 4 years ]

Enrollment: 207
Study Start Date: April 2001
Study Completion Date: September 2007
Arms Assigned Interventions
Active Comparator: High-dose Radiotherapy Radiation: High-Dose radiotherapy
Preoperative radiotherapy of 45 Gy/25 fractions of 1.8 Gy through three fields was delivered to the pelvis over 5 weeks, followed by a 18 Gy/10 fraction boost to the primary tumor over 2 weeks.
Other Name: HDRT
Active Comparator: Chemo-radiotherapy Radiation: Chemo-radiotherapy
Chemotherapy (5-fluorouracil, 200 mg per square meter of body-surface area per day) was delivered over 5 weeks concurrently with the pelvic radiotherapy.
Other Name: CTRT
