Combination Chemotherapy and Intensity-Modulated Radiation Therapy in Treating Patients Undergoing Surgery for Locally Advanced Rectal Cancer
A Phase II Evaluation of Preoperative Chemoradiotherapy Utilizing Intensity Modulated Radiation Therapy (IMRT) in Combination With Capecitabine and Oxaliplatin for Patients With Locally Advanced Rectal Cancer

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving these treatments 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.

PURPOSE: This phase II trial is studying the side effects and how well giving combination chemotherapy together with intensity-modulated radiation therapy works in treating patients undergoing surgery for locally advanced rectal cancer.

OBJECTIVES:

Primary

  • To determine whether the incidence of neoadjuvant acute gastrointestinal toxicity (grade ≥ 2) associated with neoadjuvant chemoradiotherapy is reduced by inverse-planned intensity-modulated radiotherapy (IMRT)-based radiation treatment when compared with conventionally delivered radiotherapy, as was utilized in the capecitabine and oxaliplatin arm of RTOG-0247 (NCT00081289).

Secondary

  • To evaluate the feasibility of performing IMRT in a cooperative group setting for the treatment of rectal cancer.
  • To estimate the incidence of all toxicity (hematologic and non-hematologic) associated with protocol treatment in the neoadjuvant period, the adjuvant period, and overall.
  • To estimate the pathologic complete response rate following neoadjuvant IMRT-based chemoradiotherapy.
  • To estimate the time to treatment failure and patterns of failure.
  • To correlate pre- and post-treatment levels of serum cytokines with symptoms during and pathological outcomes following neoadjuvant chemoradiotherapy for rectal cancer.
  • To evaluate the rate of abdominoperineal resections.

OUTLINE: This is a multicenter study.

  • Chemoradiotherapy: Patients undergo inverse-planned intensity-modulated radiotherapy to the pelvis once daily, 5 days a week, for 5 weeks (total of 45 Gy) and a 3-dimensional conformal radiotherapy boost to gross disease once daily for 3 days (total of 45 Gy). Beginning on the first day of radiotherapy and continuing through completion of radiotherapy, patients receive oral capecitabine twice daily, 5 days a week, for 5 weeks and oxaliplatin IV over 2 hours on days 1, 8, 15, 22, 29.
  • Surgery: Within 4-8 weeks after completion of chemoradiotherapy, patients undergo resection of the rectal tumor.
  • Adjuvant chemotherapy: Beginning 4-8 weeks after surgery, patients with completely resected disease and negative surgical margins receive leucovorin calcium IV over 2 hours and oxaliplatin IV over 2 hours on day 1 and fluorouracil IV bolus on day 1 and fluorouracil IV infusion continuously over 46 hours beginning on day 1 . Treatment repeats every 14 days for up to 9 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months after the start of treatment for 2 years, every 6 months for years 3-5, and then annually thereafter.

  • Drug: FOLFOX

    Postoperative chemotherapy is administered to all patients who have a complete resection of rectal cancer with negative surgical margins and begins within 4-8 weeks following surgical resection, consisting of a total of 9 14-day cycles. Oxaliplatin 85 mg/m^2, IV over 2 hours, day 1.

    Leucovorin 400 mg/m^2, IV over 2 hours, day 1. 5-fluorouracil bolus 400 mg/m^2, IV push, day 1. 5-fluorouracil infusion 2400 mg/m^2, IV continuous infusion over 46 hours, day 1.
