  Purpose

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether chemotherapy alone is more effective then chemotherapy plus radiation therapy in treating rectal cancer.

PURPOSE: This randomized phase II/III trial studies how well chemotherapy alone compared to chemotherapy plus radiation therapy works in treating patients with rectal cancer undergoing surgery.

Primary Outcome Measures:
  • Pelvic R0 resection rate (Phase II) [ Time Frame: Up to 18 weeks ] [ Designated as safety issue: No ]
  • DFS (Phase III) [ Time Frame: Up to 8 years ] [ Designated as safety issue: No ]
  • Time to local recurrence (TLR) [ Time Frame: Up to 8 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pathologic complete response [ Time Frame: Up to 18 weeks ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: Up to 8 years ] [ Designated as safety issue: No ]
  • Adverse event (AE) profiles [ Time Frame: Up to 8 years ] [ Designated as safety issue: Yes ]
  • Rates of receiving pre- or post-operative 5FUCMT [ Time Frame: Up to 30 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 1060
Study Start Date: January 2012
Estimated Primary Completion Date: July 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group 1
Patients receive neoadjuvant chemotherapy comprising oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1, and fluorouracil IV continuously on days 1-2. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients with at least 20% of tumor regression undergo low-anterior resection (LAR) with total mesorectal excision (TME). Patients with less than 20% of tumor regression undergo chemoradiation as in group 1 before proceeding to LAR with TME.
Drug: fluorouracil
Given IV
Drug: leucovorin calcium
Given IV
Drug: oxaliplatin
Given IV
Experimental: Group 2
Patients receive fluorouracil IV continuously 7 days a week for 5.5 weeks or capecitabine orally (PO) twice daily (BID) 5 days a week for 5.5 weeks. Patients also undergo 3-dimensional conformal or intensity-modulated radiation therapy 5 days a week for approximately 5.5 weeks. Patients then undergo LAR with TME.
Drug: capecitabine
Given PO
Drug: fluorouracil
Given IV

Criteria

DISEASE CHARACTERISTICS:

  • Diagnosis of rectal adenocarcinoma
  • Radiologically measurable or clinically evaluable disease
  • For this patient, the standard treatment recommendation in the absence of a clinical trial would be combined-modality, neoadjuvant chemoradiation followed by curative-intent surgical resection
  • Candidate for sphincter-sparing surgical resection prior to neoadjuvant therapy according to the primary surgeon

    • No patient for whom primary surgeon indicates need for abdominoperineal (APR) at baseline
  • Clinical stage T2N1, T3N0, T3N1 (stage IIA, IIIA, or IIIB)

    • Clinical staging should be estimated based on the combination of the following assessments: physical exam by the primary surgeon, CT scan of the chest/abdomen/pelvis, and either a pelvic MRI or an ultrasound (ERUS)

      • Clinical stage N2 disease is to be estimated as four or more lymph nodes that are ≥ 10 mm
      • No clinical T4 tumors
  • Preoperative proctoscopy with tumor tissue evident between 5 and 12 cm from the anal verge, inclusive

    • No evidence that tumor is adjacent to (defined as within 3 mm of) the mesorectal fascia on pre-operative MRI or ERUS/pelvic CT scan
  • No tumor causing symptomatic bowel obstruction

PATIENT CHARACTERISTICS:

  • ECOG performance status 0, 1, or 2
  • Absolute neutrophil count (ANC) ≥ 1,500/mm³
  • Platelets ≥ 100,000/mm³
  • Hemoglobin > 8.0 g/dL
  • Total bilirubin ≤ 1.5 times upper limit of normal (ULN)
  • AST and ALT ≤ 3 times ULN
  • Creatinine ≤ 1.5 times ULN
  • Not pregnant or nursing
  • Negative pregnancy test
  • Patient of child-bearing potential is willing to employ adequate contraception
  • Willing to return to enrolling medical site for all study assessments
  • No other invasive malignancy ≤ 5 years prior to registration; exceptions are colonic polyps, non-melanoma skin cancer, or carcinoma-in-situ of the cervix
  • No co-morbid illnesses or other concurrent disease that, in the judgment of the clinician obtaining informed consent, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens

PRIOR CONCURRENT THERAPY:

  • See Disease Characteristics
  • No chemotherapy within 5 years prior to registration (hormonal therapy is allowable if the disease-free interval is ≥ 5 years)
  • No prior pelvic radiation
