Brief Summary

Currently the 3-year disease free survival of patients with locally advanced rectal cancer is about 50%. Current standard treatment for patients at high risk of failing locally and/or systemically includes pre-operative long course radiotherapy (5 weeks) in combination with chemotherapy (so called neoadjuvant chemoradiotherapy). The neoadjuvant chemoradiotherapy has been demonstrated to improve local control, but had no effect on the overall survival. Different studies in patients with rectal cancer studying the effect of adjuvant post operative chemotherapy did not result in an improved survival. This may be due the fact that rectal cancer surgery (TME) is associated with a high complication rate so substantial proportion of patients cannot receive chemotherapy postoperatively. An alternative approach is to administer the systemic therapy preoperative. To guarantee control of the rectum tumor short-course radiotherapy (5 days) is given, as different studies showed local control of the tumor for a long time. During this waiting period the patient is in a good condition to receive an optimal dose of chemotherapy. The investigators hypothesize that with this proposed protocol both the local tumour and possible micrometastases are effectively treated and that this will result in an increased survival. The investigators will compare this with the standard treatment of neoadjuvant chemoradiation followed by TME surgery and optional adjuvant chemotherapy.

Outcome Measures

Primary Outcomes (1)

  • Number of Patients With Disease Related Treatment Failure (DrTF)

    DrTF = Either local or distant relapse or death caused by the rectal carcinoma whichever comes first. In case of nonrectal cancer related death patients will be censored at date of death. In case of a second primary tumour patients will be censored at the date of diagnosis of the second primary tumour. In case of local regrowth after wait \& watch strategy, followed by no resection or R2 resection, diagnosis local regrowth is taken. Patients lost to follow-up will be censored the last date of patient visit. Survival curves for Disease related Treatment Failure after 3 years of follow-up will be constructed using the method of Kaplan and Meier.

    3 years follow-up after surgery

Secondary Outcomes (9)

  • Number of Patients Completing the Prescribe Neo-adjuvant Treatment Dose

    30 days after neoadjuvant treatment

  • Number of Patients With Negative CRM Negative

    30 days after surgery

  • Number of Patients With a Pathological Complete Response (pCR)

    30 days after surgery

  • Number of Patients With Surgical Complications

    30 days after surgery

  • Quality of Life QLQ-C30 Scores

    3 year after surgery

N2, i.e. four or more lymph nodes in the mesorectum showing morphological signs on MRI indicating metastatic disease. Positive Mesorectal Fascia (MRF+), i.e. tumor or lymph node \< 1 mm from the mesorectal fascia. Enlarged lateral nodes (LN), \> 1 cm (lat LN+)

  • Presence of metastatic disease or recurrent rectal tumour
  • Familial Adenomatosis Polyposis coli (FAP), Hereditary Non-Polyposis Colorectal Cancer (HNPCC), active Crohn's disease or active ulcerative Colitis
  • Concomitant malignancies, except for adequately treated basocellular carcinoma of the skin or in situ carcinoma of the cervix uteri. Subjects with prior malignancies must be disease-free for at least 5 years
  • Known Dihydro-Pyrimidine Dehydrogenase (DPD) deficiency

  • Concurrent uncontrolled medical conditions
  • Any investigational treatment for rectal cancer within the past month
  • Pregnancy or breast feeding
  • Patients with known malabsorption syndromes or a lack of physical integrity of the upper gastrointestinal tract
  • Clinically significant (i.e. active) cardiac disease (e.g. congestive heart failure, symptomatic coronary artery disease and cardiac dysrhythmia, e.g. atrial fibrillation, even if controlled with medication) or myocardial infarction within the past 12 months
  • Patients with symptoms or history of peripheral neuropathy
