Combination Chemotherapy and Intensity-Modulated Radiation Therapy in Treating Patients Undergoing Surgery for Locally Advanced Rectal Cancer

Phase 2
Completed
Conditions
Colorectal Cancer
Interventions
Procedure: resection
Radiation: radiation therapy
Drug: FOLFOX
Registration Number
NCT00613080
Lead Sponsor
Radiation Therapy Oncology Group
Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
The Percentage of Patients Experiencing Treatment-related Gastrointestinal Adverse Events ≥ Grade 2 Per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v. 3.0, Occurring PreoperativelyFrom start of treatment to surgery or ≤ 90 days from the Start of Concurrent Treatment (for patients not undergoing surgery)

The percentage of patients experiencing preoperative treatment-related gastrointestinal adverse events ≥ grade 2. If patient did not receive surgery, then such adverse events \<= 90 days from the start of concurrent treatment are included.

Secondary Outcome Measures
NameTimeMethod
Overall Survival: 4-year RateFrom registration to four years

Overall survival time is defined as time from registration to the date of death from any cause. Overall survival rates are estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact.

Number of Patients in Protocol Adherence Categories for Intensity-modulated Radiotherapy (IMRT) PlanningPretreatment

Real-time quality assurance was performed remotely by the study chair or the radiation oncology co-chair prior to initiation of treatment for the first 40 cases. The final cases enrolled were reviewed within 3 months after accrual was completed. Review included evaluation of clinical target volume (CTV) and planning target volume (PTV), Organs at Risk (OARs), and treatment plan dosimetry.

Local-regional Failure: 4-year RateFrom registration to four years

Local failure is defined as: (1) any recurrence or surgery to the primary site after a complete response (CR) reported at surgery or reported after the end of protocol treatment; or (2) persistence \[failure at one day post study entry\], absence of CR after protocol treatment was completed and patient lived at least 90 days from the end of treatment. Regional failure is defined as: (1) any recurrence after a nodal CR reported at surgery or reported after the end of protocol treatment; or (2) persistence, absence of nodal CR after protocol treatment was completed and patient lived at least 90 days from the end of treatment. Local-regional failure time is defined as time from registration to local or regional failure, last known follow-up (censored), or death (competing risk). Local-regional failure rates are estimated by the cumulative incidence method.

Disease-free Survival: 4-year RateFrom registration to four years

Disease is defined as local-regional failure or distant failure. Distant failure is defined as the appearance of peritoneal seeding or distant metastases. Local-regional failure is defined as: (1) any recurrence or surgery to the primary site after a complete response (CR) / any recurrence after a nodal CR - reported at surgery or reported after the end of protocol treatment; or (2) persistence \[failure at one day post study entry\], absence of primary/nodal CR after protocol treatment was completed and patient lived at least 90 days from the end of treatment. Disease-free survival time is defined as time from registration to the date of disease, death, or last known follow-up (censored). Disease-free survival rates are estimated using the Kaplan-Meier method.

Number of Patients Who Underwent Abdominoperineal ResectionSurgery occurred 4 to 8 weeks following the completion of radiation therapy, approximately 9-13 weeks from start of treatment.

All patients were to undergo surgery 4 to 8 weeks following the completion of radiation therapy. The choice of procedure (abdominoperineal resection (APR), low anterior resection (LAR), or LAR/coloanal anastomosis) was at the discretion of the surgeon. If more than 28 patients received abdominoperineal resection, this would result in a conclusion of an excessive number of abdominoperineal resections.

Number of Patients With Pathologic Complete ResponseAt the time of surgery, which is 4-8 weeks after radiation therapy, approximately 9-13 weeks from treatment start.

Pathologic complete response is defined as no evidence of residual cancer histologically in the resection specimen.

Percentage of Patients With Grade 3 or Higher Treatment-related Adverse Events as Assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v3.0From study registration to end of follow-up. Maximum follow-up at time of analysis was 5.2 years.

Grade refers to the severity of the adverse event (AE). The CTCAE v3.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE, Grade 2 Moderate AE, Grade 3 Severe AE, Grade 4 Life-threatening or disabling AE, Grade 5 Death related to AE. Adverse events were compiled in four different time periods: 1) Preoperative: Preoperatively or, if no surgery, then ≤ 90 days from the Start of Concurrent Treatment; 2) Postoperative#1: Postoperatively and ≤ 30 days from the Date of Surgery; 3) Postoperative#2: Postoperatively and ≤ 90 days from the End of Postoperative Chemotherapy; 4) Overall: From start of concurrent treatment to end of follow-up;

Distant Failure: 4-year RateFrom registration to four years

Distant failure is defined as the appearance of peritoneal seeding or distant metastases. Time to distant failure is defined as time from registration to the date of distant failure, last known follow-up (censored), or death (competing risk). Distant failure rates are estimated by the cumulative incidence method.
