Summary
This is a multicenter, prospective, randomized, stratified, controlled, open-label study comparing preoperative FOLFOX versus postoperative risk-adapted chemotherapy in patients with locally advanced rectal cancer and low risk for local failure
Eligibility
Inclusion Criteria18
- Staging requirements: High-resolution magnetic resonance imaging (MRI) of the pelvis is the mandatory local staging procedure.
- Transrectal endoscopic ultrasound (EUS) is used to help discriminate between T1/2 and early T3 tumors.
- i. Lower third (0-6 cm):
- cT1/2 with clear cN+ based on defined MRI criteria or T3a-b (i.e. maximum infiltration into the perirectal fat of 5mm), provided CRM \> 2mm and EMVI-\*\* ii. Middle third (≥ 6-12 cm):
- cT1/2 with clear cN+ provided CRM- and EMVI-\*\*
- cT3 irrespective of the depth of invasion into the perirectal fat, provided no evidence that tumor is adjacent to (defined as within 2 mm of) the mesorectal fascia on MRI (i.e. CRM \> 2 mm), N0 or N1, EMVI-\*\* iii. Upper third (≥ 12-16 cm):
- cT1/2 with clear cN+, irrespective of CRM and EMVI
- any cT3-4 irrespective of nodal status, CRM and EMVI.
- Spiral-CT of the abdomen and chest to exclude distant metastases.
- Aged at least 18 years. No upper age limit.
- WHO/ECOG Performance Status ≤1.
- Adequate haematological, hepatic, renal and metabolic function parameters:
- Leukocytes ≥ 3.000/mm³, ANC ≥ 2.000/mm³, platelets ≥ 100.000/mm³, Hb \> 9 g/dl
- Serum creatinine ≤ 1.5 x upper limit of normal
- Bilirubin ≤ 2.0 mg/dl, SGOT-SGPT, and AP ≤ 3 x upper limit of normal.
- QTc interval (Bazett\*\*) ≤ 440 ms
- Informed consent of the patient.
- "\*\*" Formula for QTc interval calculation (Bazett): QTc= ((QT) ̅" (ms)" )/√(RR (sec))= ((QT) ̅" (ms)" )/√(60/(frequency (1/min)))
Exclusion Criteria21
- Distant metastases (to be excluded by CT scan of the thorax and abdomen).
- Prior antineoplastic therapy for rectal cancer.
- Prior radiotherapy of the pelvic region.
- Major surgery within the last 4 weeks prior to inclusion.
- Subject pregnant or breast feeding, or planning to become pregnant within 6 months after the end of treatment.
- Subject (male or female) is not willing to use highly effective\*\*\* methods of contraception during treatment and for 6 months (male or female) after the end of treatment Male patients treated with Oxaliplatin should take legal advice concerning sperm conservation before start of therapy and should additionally use a condom during treatment period. Their female partner of childbearing potential should also use an appropriate contraceptive measure.
- On-treatment participation in a clinical study in the period 30 days prior to inclusion.
- Previous or current drug abuse.
- Other concomitant antineoplastic therapy.
- Serious concurrent diseases, including neurologic or psychiatric disorders (incl. dementia and uncontrolled seizures), active, uncontrolled infections, active, disseminated coagulation disorder.
- Clinically significant cardiovascular disease in (incl. myocardial infarction, unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia) ≤ 6 months before enrolment.
- Chronic diarrhea (\> grade 1 according NCI CTCAE).
- Prior or concurrent malignancy ≤ 3 years prior to enrolment in study (Exception: non-melanoma skin cancer or cervical carcinoma FIGO stage 0-1), if the patient is continuously disease-free.
- Known allergic reactions or hypersensitivity on study medication or to any of the other excipients.
- Evidence of peripheral sensory neuropathy \> grade 1 according to CTCAE version 5.0 (see appendix).
- Severe kidney dysfunction (creatinine clearance \< 30 ml/min).
- Recent or concurrent treatment with brivudine.
- Pernicious or other megaloblastic anaemia caused by vitamin B12 deficiency.
- Known dihydropyrimidine dehydrogenase deficiency.
- Psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule (these conditions should be discussed with the patient before registration in the trial).
- "\*\*\*"highly effective (i.e. failure rate of \<1% per year when used consistently and correctly) methods: intravaginal and transdermal combined (estrogen and progestogen containing) hormonal contraception; injectable and implantable progestogen-only hormonal contraception; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomized partner; sexual abstinence (complete abstinence is defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments).
