Chemotherapy, Radiation Therapy, and Surgery in Treating Patients With Locally Advanced Rectal Cancer

Completed · Phase 1

Conditions studied: Adenocarcinoma of the Rectum, Mucinous Adenocarcinoma of the Rectum, Signet Ring Adenocarcinoma of the Rectum, Stage IIA Rectal Cancer, Stage IIB Rectal Cancer, Stage IIC Rectal Cancer, Stage IIIA Rectal Cancer, Stage IIIB Rectal Cancer, Stage IIIC Rectal Cancer

In brief

Phase I trial to study the effectiveness of radiation therapy plus chemotherapy followed by surgery and additional chemotherapy in treating patients who have advanced nonmetastatic primary cancer of the rectum. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy, radiation therapy, and surgery may be an effective treatment for rectal cancer

You may qualify if…

• Histologically confirmed, locally advanced, non-metastatic primary T3 or T4 primary adenocarcinoma of the rectum
• No evidence of tumor outside of the pelvis including liver metastases, peritoneal seeding, or metastatic inguinal lymphadenopathy
• No intra-operative radiotherapy (IORT) or brachytherapy will be allowed
• The distal border of the tumor must be at or below the peritoneal reflection, defined as within 12 centimeters of anal verge by proctoscopic examination
• Transmural penetration of tumor through the muscularis propria must be demonstrated by either of the following:
• CT scan plus endorectal ultrasound or
• MRI
• Tumors must be defined prospectively by the surgeon as clinically resectable or not; clinically resectable tumors will be defined by the surgeon as mobile and completely resectable with negative margins based on the routine examination of the non-anesthetized patient; before pre-op treatment, the surgeon should estimate and record the type of resection anticipated: APR, LAR, or LAR/coloanal anastomosis
• The tumor may be clinically fixed or initially not completely resectable, clinical stage T4, N0-2, M0 based on the presence of at least one of the following criteria:
• Clinically fixed tumors on rectal examination with tumor adherent to the pelvic sidewall or sacrum
• Sciatica attributed to sacral root invasion with CT scan/MRI evidence of the lack of clear tissue plane will be considered evidence of fixation
• Hydronephrosis on CT scan or IVP or ureteric or bladder invasion as documented by cystoscopy and cytology or biopsy, or invasion into prostate
• Vaginal or uterine involvement
• ECOG performance status 0-2 and surgical evaluation confirms the patient's medical condition would tolerate the proposed surgical procedure
• Caloric intake should be >= 1500 kilocalories/d
• WBC >= 3500/uL
• Platelets >= 100,000/uL
• Serum creatinine =< 2.0 mg/dL
• Serum bilirubin less than 2.0 mg/dL
• Alk Phos =< 2 x ULN
• SGOT =< 2 x ULN
• CEA should be determined prior to initiation of therapy
• Absence of clinical evidence of high-grade (lumen diameter < 1cm) large bowel obstruction, unless diverting colostomy has been performed
• Pregnant or lactating women are not eligible
• Women of childbearing potential and sexually active males are strongly advised to use an accepted and effective method of contraception
