Trial Description


This is a multi-centre randomised trial comparing long course (LC) preoperative chemoradiation with short course (SC) preoperative radiotherapy for patients with localised T3 rectal cancer.

Further Study Information


  • The objective is, in patients with T3 clinically resectable carcinoma of the rectum, to demonstrate that the local recurrence rate in patients treated with a long course (LC) of pre-operative radiotherapy with continuous infusion 5-FU is lower than that in patients treated with a short course (SC) of pre-operative radiotherapy with early surgery

Eligibility Criteria:

  • The main eligibility criteria are that the patient has clinically resectable adenocarcinoma of the rectum, a clinical stage T3 tumour whose lower border is within 12 cm of the anal verge, and no evidence of distant metastases.


  • Primary endpoint is local recurrence.
  • Secondary endpoints are overall survival, toxicity, abdminoperineal resection rate, quality of life.

Treatment arms:

  • SC arm: Radiotherapy (RT) 25 Gy in 5 fr in 1 week to be followed by surgery within 1 week and 6 cycles of postoperative chemotherapy 5FU/Folinic acid.
  • LC arm: RT 50.4 Gy in 28 fr in 5½weeks with 5FU 225 mg/m2/day throughout the course of RT, to be followed by surgery 4-6 weeks after completion of RT. 4 cycles of adjuvant 5FU/Folinic acid will be given.

Eligibility Criteria

Inclusion Criteria:

All of the following must apply:

  • Pathologically documented and clinically resectable adenocarcinoma of the rectum.
  • The patient must be considered by the surgeon to be suitable for a curative resection.
  • The patient must be considered by the radiation oncologist to have no contraindication to pre-operative radiotherapy.
  • Clinical T3 stage tumour on endorectal ultrasound or MRI. When endorectal ultrasound cannot be performed satisfactorily due to a technical reason, such as stenosis or proximity of the tumour, and MRI is not available, infiltration of perirectal fat on CT scan is also acceptable.
  • Tumour with lower border within 12 cm from anal verge on rigid sigmoidoscopy.
  • ECOG performance status 0, 1 or 2.
  • Adequate bone marrow function with neutrophil count at least 1.5 x 109/L and platelet count at least 100 x 109/L.
  • Adequate liver function with bilirubin and alanine aminotransferase (ALT) <= 1.5 times the upper limit of normal.
  • Adequate renal function with serum creatinine <= 1.5 times the upper limit of normal.
  • Accessibility for treatment and follow-up.
  • Written informed consent.

Exclusion Criteria:

  • None of the following must apply:
  • Evidence of distant metastases.
  • Recurrent rectal cancer.
  • Unstable cardiac disease or clinically significant active infection.
  • Other cancer in the last 5 years except treated non-melanoma skin cancer or carcinoma in situ of the cervix.
  • Pregnant or lactating females or female patients of childbearing potential who have not been surgically sterilized or are without adequate contraceptive measures.
  • Contraindication to insertion of a suitable indwelling venous catheter e.g. implantable central venous device (infuse-a-port), Hickman catheter or peripherally inserted central catheter.
  • Prior pelvic or abdominal radiotherapy.
