Study Evaluating the Tailored Management of Locally-advanced Rectal Carcinoma
Multicentric Phase II-III Study Evaluating the Tailored Management of Locally-advanced Rectal Carcinoma After a Favorable Response to Induction Chemotherapy
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. szept. 2.
Rövid összefoglaló (regiszter, angolul)
Locally advanced rectal carcinoma raise the issue of both the oncological control, local and general, and the therapeutic morbidity. Surgery alone can cure only one out of two patients, radiochemotherapy improves the local control but the metastatic risk remains about 30% with enhanced postoperative morbidity and poor functional results. The tumor response to preoperative treatment is the major prognostic factor which revealed the aggressiveness of the tumor. To this day, there are no biologic predictive markers for tumor response. The purpose of this trial is to tailor the management according to the early tumoral response after short and intensive induction chemotherapy. MRI volumetric tumor response will be used to distinguish between good responders and bad responders. "Very good" responders will be randomized to either immediate surgery or radiochemotherapy followed by surgery (Standard arm: Cap 50).

- Histologically confirmed diagnosis of adenocarcinoma of the rectum,
- Distal part of the tumor from 1 to 12 cm from the upper part of the levator ani (dynamic rectal examination),
- No unequivocal evidence on CT-Scan of established metastatic disease,
- MRI evaluation of the locally advanced tumor before neoadjuvant chemotherapy:
- Predictive CRM < 2 mm
- Or T3c-d (extending ≥ 5 mm beyond the muscularis propria) with extra mural venous invasion (EMVI)
- Or T4a-b (except bone and sphincteric invasion).
- NON INCLUSION CRITERIA FOR SCREENING

Unstable angina (angina symptoms at rest), new-onset angina (begun within the last 3 months), c. Myocardial infarction less than 6 months before first dose of treatment, d. Cardiac arrhythmias requiring anti-arrhythmic therapy (beta blockers or digoxin are permitted),
- Previous or concurrent cancer that is distinct in primary site or histology from colorectal cancer within 5 years prior to study inclusion, except for curatively treated cervical cancer in situ, non-melanoma skin cancer and superficial bladder tumors [Ta (non invasive tumor), Tis (carcinoma in situ) and T1 (lamina propria invasion)],
- Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 6 months before start of treatment.
