Primary	Percentage of Subjects With Acute Gastrointestinal (GI) and Genitourinary (GU) Adverse Events (AE) ≥ Grade 2 as Defined by CTCAE v3.0 (Common Terminology Criteria for Adverse Events)	From the start of treatment to 90 days	Highest grade adverse event per subject were counted. Adverse events were graded using CTCAE v3.0. Grade refers to the severity of the 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. Acute toxicities occur within 90 days of the start of treatment.
Secondary	Number of Patients With Major Radiation Planning Deviations	Planning occurred prior to radiation therapy	Deviations in intensity-modulated radiation therapy technique (IMRT) planning were determined by central review by the radiation oncology co-chairs of the study.
Secondary	Percentage of Subjects With Acute Adverse Events (AE)	From the start of treatment to 90 days	Highest grade adverse event per subject were counted. Adverse events were graded using CTCAE v3.0. Grade refers to the severity of the 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. Acute toxicities occur within 90 days of the start of treatment.
Secondary	Percentage of Subjects With Late Adverse Events (AE)	From 91 days after start of study treatment to the end of follow-up. Maximum follow-up at time of analysis was 9.2 years.	Highest grade adverse event per subject were counted. Adverse events were graded using CTCAE v3.0. Grade refers to the severity of the 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. Late toxicities occur greater than 90 days from the start of treatment.
Secondary	Clinical Complete Response Rate	8 and 12 weeks after treatment completion (corresponding to 14 and 18 weeks from registration)	A complete clinical response was defined as complete resolution of all palpable tumor determined by digital rectal exam and proctosigmoidoscopy supplemented with pelvic axial imaging.
Secondary	Duration of Radiotherapy Treatment	From start to end of radiation therapy (6 weeks)	Number of days from radiotherapy treatment start to radiotherapy treatment end
Secondary	Five-year Rate of Overall Survival	From registration to 5 years	Overall survival time is defined as time from registration/randomization 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.
Secondary	Five-year Rate of Disease-free Survival	From registration to 5 years	Disease-free survival time is defined as time from registration to the date of local-regional failure, the appearance of distant metastases, the appearance of a second primary failure, or date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive without failure are censored at the date of last contact. Local failure is defined as any measurable disease after 12 weeks from the completion of chemoradiation therapy. Local failure is defined as: a) For patients with no disease in pelvic and/or groin nodes, the appearance of disease in pelvic or groin nodes; b) For patients with disease in pelvic and/or groin nodes at study entry, nodal recurrence following clearance or persistent nodal disease for more than 12 weeks after completion of treatment.
Secondary	Five-Year Cumulative Incidence Rate of Local-regional Failure	From registration to 5 years	Local-regional failure time is defined as time from registration to date of failure and is estimated by the cumulative incidence method. Patients last known to be alive without failure are censored at the date of last contact. Local-regional failure is defined as a local or regional failure. Local failure is defined as any measurable disease after 12 weeks from the completion of chemoradiation therapy. Regional failure is defined as: a) For patients with no disease in pelvic and/or groin nodes, the appearance of disease in pelvic or groin nodes; b) For patients with disease in pelvic and/or groin nodes at study entry, nodal recurrence following clearance or persistent nodal disease for more than 12 weeks after completion of treatment.
Secondary	Five-Year Cumulative Incidence Rate of Distant Failure	From registration to 5 years	Distant failure time is defined as time from registration to the appearance of distant metastases and is estimated by the cumulative incidence method. Patients last known to be alive without failure are censored at the date of last contact.
Secondary	Five-Year Cumulative Incidence Rate of Colostomy Failure	From registration to 5 years	Colostomy failure time is defined as time from registration to the date of colostomy or abdominoperineal (A-P) resection and is estimated by the cumulative incidence method. Patients last known to be alive without failure are censored at the date of last contact.
Secondary	Five-Year Rate of Colostomy-free Survival	From registration to 5 years	Colostomy-free survival time is defined as time from registration to date of colostomy or abdominoperineal (A-P) resection, or date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive without failure are censored at the date of last contact.
