Rectal Cancer | Drug: 64Cu-ATSM | Phase 2 |
The purpose of this study is to evaluate early and late tumor uptake of 64Cu-ATSM in predicting histological response to neo-adjuvant chemo-radiotherapy treatment in patients with locally advanced rectal cancer.
Patients receive pre-therapeutic CT scan, Pelvic MRI and 18FDG (fluorodeoxyglucose) PET/CT (positron emission tomography) scan within 45 days before enrollment.
64Cu-ATSM PET/CT scan is done before chemoradiotherapy treatment start. About 3 MBq/Kg of 64Cu-ATSM are injected intravenously, two acquisition sequences are performed 1 hour and 23 to 25 hours after injection in order to evaluate early and late tumor uptake of 64Cu-ATSM.
Patients are treated for 5 weeks by Capecitabine chemotherapy (1600 mg/m2/day) combined to 50 Gy radiotherapy.
Pelvic MRI is performed 4 weeks after chemotherapy in order to evaluate the treatment efficacy.
Surgery is scheduled 6 to 8 weeks after chemoradiotherapy. Tissue samples from previously collected rectal biopsy (obtained for diagnosis) and from surgery are used for assessing oxidative stress markers by Immuno-histochemical analysis.
Chest, abdomen and pelvis CT scan is performed every 6 months after surgery in order to assess progression free survival.

- Relationship between early tumor uptake of 64Cu-ATSM PET/CT images and prediction of histological response to neo-adjuvant chemo-radiotherapy treatment [ Time Frame: 4 months ]Early tumor uptake of 64Cu-ATSM will be assessed by SUV (Standardized Uptake Value) measurement, histological response Will be assessed by Rodel grading (Tumor Regression Grading)
- Relationship between late tumor uptake of 64Cu-ATSM PET/CT images and prediction of histological response to neo-adjuvant chemo-radiotherapy treatment [ Time Frame: 4 months ]Late tumor uptake of 64Cu-ATSM will be assessed by SUV (Standardized Uptake Value) measurement, histological response Will be assessed by Rodel grading (Tumor Regression Grading)
- Correlation between 64Cu-ATSM uptake and oxidative stress markers [ Time Frame: 4 months ]Aggressive zones corresponding to high redox potential areas will be assessed by Immuno-histochemical analysis on the surgical sample and on the pre-therapeutic biopsy
- Progression free survival [ Time Frame: 2 years ]Progression Free survival is the delay between surgery and the date of documented disease progression
- 18FDG-PET/CT and 64Cu-PET/CT uptakes [ Time Frame: 45 days ]Correlation between 18FDG-PET/CT and 64Cu-PET/CT uptakes
- Comparison between early and late 64Cu-ATSM uptakes in 64Cu-ATSM PET/CT images [ Time Frame: 45 days ]Early and Late tumor uptake of 64Cu-ATSM will be assessed by SUV (Standardized Uptake Value) measurement
- 64Cu-ATSM toxicity [ Time Frame: 45 days ]64Cu-ATSM toxicity will be assessed by vital signs monitoring within 2 hours after 64Cu-ATSM injection
