Chemotherapy and Radiation Therapy Before Surgery Followed by Capecitabine With or Without Oxaliplatin in Treating Patients With Locally Advanced Rectal Cancer
Preoperative Chemoradiotherapy and Postoperative Chemotherapy With Capecitabine and Oxaplatin vs.Capecitabine Alone in Locally Advanced Rectal Cancer (PETACC-6)

RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, 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. Giving radiation therapy that uses a 3-dimensional image of the tumor to help focus thin beams of radiation directly on the tumor may kill more tumor cells and have fewer side effects. Giving chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether capecitabine is more effective with or without oxaliplatin in treating patients with rectal cancer.

PURPOSE: This randomized phase III trial is studying giving chemotherapy together with radiation therapy before surgery followed by capecitabine with or without oxaliplatin to see how well it works in treating patients with locally advanced rectal cancer.

OBJECTIVES:

Primary

  • Investigate whether the addition of oxaliplatin to neoadjuvant chemoradiotherapy and adjuvant chemotherapy comprising capecitabine improves disease-free survival in patients with locally advanced rectal cancer.

Secondary

  • Compare the overall survival of patients with locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy and adjuvant chemotherapy comprising capecitabine with versus without oxaliplatin.
  • Determine the loco-regional failure and distant failure of patients treated with these regimens.
  • Determine the pathological down-staging (ypT0-2N0) of patients treated with these regimens.
  • Determine the pathological complete remission (yp T0N0) rate of patients treated with these regimens.
  • Determine the tumor progression grade and histopathological R0 resection of patients treated with these regimens.
  • Determine the sphincter preservation rate of patients treated with these regimens.
  • Determine the perioperative complication rate of these regimens in these patients.
  • Determine the toxicity of these regimens in these patients.

OUTLINE: This is a multicenter study. Patients are stratified according to treating center, clinical T category (T1-3 vs T4), clinical nodal status (Nx vs NO vs N1-2), distance from the tumor to the anal verge (≤ 5 cm vs > 5 cm) and method of locoregional staging (EUS+MRI vs EUS+CTscan vs MRI alone). Patients are randomized to 1 of 2 treatment arms.

  • Arm I (control):

    • Neoadjuvant therapy: Patients receive oral capecitabine twice daily on days 1-35. Patients also undergo concurrent 3-dimensional conformal radiotherapy 5 days a week on days 1-33 followed by surgery. Patients may receive additional chemoradiotherapy on days 36-38.
    • Adjuvant therapy: Beginning 4-8 weeks after surgery, patients receive oral capecitabine twice daily on days 1-15. Treatment repeats every 3 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.
  • Arm II (investigational):

    • Neoadjuvant therapy: Patients receive oral capecitabine twice daily and undergo concurrent 3-dimensional conformal radiotherapy 5 days a week on days 1-33. Patients also receive oxaliplatin IV over 1 hour on days 1, 8, 15, 22, and 29 prior to radiotherapy followed by surgery. Patients may receive additional chemoradiotherapy on days 36-38.
    • Adjuvant therapy: Beginning 4-8 weeks after surgery, patients receive oxaliplatin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-15. Treatment repeats every 3 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed every 3 months for 3 years, and then every 6 months for 2 years.

Phase 3
Allocation: Randomized
Masking: Open Label
Primary Purpose: Treatment
Colorectal Cancer
  • Drug: capecitabine
    Given orally
  • Drug: oxaliplatin
    Given IV
  • Active Comparator: Arm I
    Patients receive oral capecitabine twice daily and undergo concurrent 3-dimensional conformal radiotherapy 5 days a week on days 1-33. Patients may receive additional chemoradiotherapy on days 36-38. Patients then undergo surgery. Beginning 4-8 weeks after surgery, patients receive capecitabine twice daily on day 1-15. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
    Intervention: Drug: capecitabine
  • Experimental: Arm II
    Patients receive oral capecitabine twice daily and undergo concurrent 3-dimensional conformal radiotherapy 5 days a week on days 1-33. Patients also receive oxaliplatin IV over 1 hour on days 1, 8, 15, 22, and 29 prior to radiotherapy followed by surgery. Patients may receive additional chemoradiotherapy on days 36-38. Beginning 4-8 weeks later, patients receive oxaliplatin IV over 2 hours on day 1, and oral capecitabine twice daily on days 1-15. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
