Label	Type	Description	Intervention Names
XELOX-RT	Experimental	Xeloda: 1300 mg/m2 chronomodulated (h 8.00 a.m. 25% of total dose ; h 6.00 p.m. 25% of total dose; h 11.00 p.m. 50% of total dose), during the whole treatment time; Oxaliplatin: 130mg/m2, days 1, 19, 38 RT: pelvic treatment is the same for both arms: 45 Gy are delivered to the whole pelvis at 1.8 Gy daily, 5 times per week; In the XELOX-RT arm a boost of 5.4 Gy is delivered to the mesorectum corresponding to GTV, at 1.8 Gy daily, in 3 fractions, to a total dose of 50.4 Gy. The boost will be delivered at the end of the irradiation of the pelvis (sequential boost).	Drug: XELOX RT
XELAC-RT	Active Comparator	Xeloda 1650mg/m2 chronomodulated (h 8.00 a.m. 25% of total dose ; h 6.00 p.m. 25% of total dose; h 11.00 p.m. 50% of total dose) during the whole treatment time. RT: pelvic treatment is the same for both arms: 45 Gy are delivered to the whole pelvis at 1.8 Gy daily, 5 times per week. In the XEL-ACRT arm a boost of 10 Gy is delivered to the mesorectum corresponding to the GTV, at 1 Gy for fraction to a total dose of 55 Gy, in 10 fractions over 5 weeks, 2 times a week. The daily dose of the boost will be delivered twice a week immediately after the daily dose administered to the pelvis (concomitant boost).	Drug: XELAC RT

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Pathological major downstaging	INTERACT study: evaluation of T pathological major downstaging, considered as the overall rate of any TRG1 or TRG 2 scored patients; LEADER study (optional): To evaluate the impact on local control of local excision in patients who had a major clinical response, evaluated by EUS/ MRI, yN0 evaluated by multislice CT / MRI, and confirmed by TRG 1-2 score.	15-20 weeks after the randomization

Secondary Outcomes

Measure	Description	Time Frame
Tumor downstaging	Secondary objectives: Tumour downstaging, evaluated by the comparison of clinical staging before combined modality treatment toward pathological staging. feasibility of a sphincter saving surgical procedure; evaluation of activity of preoperative treatment (clinical response, facultative) post-surgical functional outcome; evaluation of the local control of the disease; estimates (Kaplan-Meier, product limit method) of the disease free survival; Evaluation of adverse events and adverse reactions to treatment, according to both the RTOG and NCI-CTC criteria.

Eligibility Module

Eligibility Criteria

INTERACT STUDY

Inclusion Criteria:

Histologically confirmed primary adenocarcinoma of the rectum.
Tumour within 12 cm of the anal verge by proctoscopic examination or within 10 cm of the anorectal ring by MRI.
Clinical stages (UICC 1997): cT2N0-2 low located tumour, cT3 N0-2.
Resectable disease at the routine examination.
Age > 18 years.
Karnofsky Performance Status > 60.
WBC > 4,000 cells/ml, platelets > 100,000 cells/ml.
Provision of written informed consent.

Exclusion Criteria:

Evidence of metastatic (M1) disease. If there were any suspicious findings (i.e. liver metastasis, lung nodule, retroperitoneal adenopathy, etc.) the patient is to be considered as ineligible, unless malignancy is ruled out by tissue documentation (biopsy) before trial therapy is started.
Previous chemotherapy, immunotherapy, or radiation therapy to the pelvis.
Multiple primary cancers involving both the colon and rectum that would preclude a patient from being classified as having only rectal cancer.
Incomplete healing from or other surgery.
Active inflammatory bowel disease.
Other co-existing malignancies or malignancies diagnosed within the last 5 years with the exception of basal cell carcinoma or cervical cancer in situ.
Cardiovascular disease with a New York Heart Association Functional Status > 2.
Absolute neutrophil count (ANC) < 4 x 108/L or platelets < 50 x 108/L.
Measured Creatinine clearance less than 65ml/min. (no drug dose reduction for lower GFR is allowed).
ALT or AST > 2.5 times the ULRR
Pregnancy or breastfeeding (women of child-bearing potential).
Any evidence of severe or uncontrolled systemic disease (e.g. unstable or uncompensated respiratory, cardiac, hepatic or renal disease).
Any other significant clinical disorder or laboratory finding that makes it undesirable for the patient to participate in the trial.

LEADER STUDY

Inclusion Criteria

Stage at the diagnosis: cT3N0. T3 patients at the diagnosis with 3 or less enlarged nodes, evaluated by imaging, and without evidence of the same nodes after radiochemotherapy, could be accrued according to Center decision, but will be analyzed separately.
Patients with cT2N0, low located tumour, otherwise candidates to a Miles surgical procedure, treated by neoadjuvant chemoradiation and with written consensus;
Major clinical response after chemoradiation, yT0-1N0; yT2N0 could be accrued according to Center decision, but will be analyzed separately.
Circumferential extension less than 2 quarters;
Deep ulcer < 2 cm of diameter;
Provision of written informed consent;
Biopsies are discouraged for the higher risk of following fistulae in irradiated rectum;

Exclusion Criteria:

pT3;
Positive margins;
TRG 3-5;
Major adverse features: lymphatic vessel invasion, vascular vessel invasion, perineural invasion;
