Alternate Title

Neoadjuvant Celecoxib and Capecitabine Combined With Pelvic Irradiation in Treating Patients With Stage II or Stage III Adenocarcinoma (Cancer) of the Rectum

Basic Trial Information

Objectives

Primary

1. Determine the pathological complete response rate in patients with stage II or III adenocarcinoma of the rectum treated with neoadjuvant celecoxib and capecitabine in combination with pelvic irradiation.

Secondary

1. Determine the safety and tolerability of this regimen in these patients.
2. Determine the rectal function of patients treated with this regimen.
3. Determine the time to recurrence or progression and survival time of patients treated with this regimen.
4. Correlate cellular and molecular markers in pretreatment tumor samples with response in patients treated with this regimen.

Entry Criteria

Disease Characteristics:

• Histologically confirmed rectal adenocarcinoma
  • Clinical stage T3, N0, M0 OR any T, N1-3, M0 disease
• Treatment with neoadjuvant chemotherapy and pelvic radiotherapy is indicated
  • All disease must be encompassable within standard pelvic radiotherapy fields
• Distal border of the tumor must be at or below* the peritoneal reflection, defined as within 12 cm of the anal verge by endoscopy

   [Note: *If a portion of the tumor is below the peritoneal reflection at the time of surgery, patients are eligible regardless of the distance of the tumor determined at endoscopy]

• Tumor must be determined to be clinically resectable
  • Tumor may not be clinically fixed
  • Negative margins by routine examination of an unanesthetized patient
• Transmural penetration of tumor through the muscularis propria by CT scan, endorectal ultrasound, or MRI
• No distant metastatic disease
  • No evidence of tumor outside the pelvis, including any of the following:
    • Metastatic inguinal lymphadenopathy
    • Peritoneal seeding
    • Liver metastases

• No other malignancy within the past 5 years except basal cell or squamous cell skin cancer or carcinoma in situ of the cervix
• No known sensitivity to NSAIDs, sulfonamides, or aspirin
• No other serious medical illness that would preclude study treatment
• No other conditions that would preclude study participation
• Must be able to tolerate major surgery that may include abdominal-perineal resection
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception during and for 30 days after study treatment

Outline

This is a multicenter study.

• Neoadjuvant chemoradiotherapy: Patients receive oral celecoxib twice daily on days 1-7 and oral capecitabine twice daily on days 1-5. Patients undergo pelvic radiotherapy once daily on days 1-5. Courses repeat weekly for 5.5 weeks.
• Surgery: Patients undergo surgery 4-6 weeks after completion of neoadjuvant chemoradiotherapy.
• Adjuvant chemotherapy: Patients with a curative resection receive oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days for up to 4 courses.

Treatment continues in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 1 year and then every 6 months for 4 years.
