Brief Summary:

The purpose of this study is to investigate the activity of panitumumab in combination with standard preoperative radiotherapy in locally advanced rectal cancer, followed by complete surgery and adjuvant chemotherapy.

The main hypothesis of the study is that the association of EGFR-targeting agent and radiation therapy could be as effective or even improve the rate of pathological complete tumoral response with fewer toxicities in comparison to the standard of care using chemoradiation therapy.

Condition or disease Intervention/treatment Phase
Rectal Cancer Drug: panitumumab Phase 2

Detailed Description:

Anti-EGFR monoclonal antibodies have radiosensitizing properties. In particular, cetuximab in combination with curative-intent radiotherapy has been reported to increase median overall survival over radiation therapy alone in locally advanced head and neck carcinoma.

Similar benefit in rectal cancer is expected. However, preliminary studies revealed that the combination of chemoradiation and cetuximab did not seem to improve the pathological tumor response. However, in the past studies, the selection of patients' population was not optimal since KRAS mutational status was not considered during recruitments.

Therefore, new trials to investigate EGFR-targeting therapies in combination with radiotherapy in wild-type KRAS patients are required.

Adjuvant chemotherapy has also shown to decrease the risk of local relapse in patients who did not receive chemotherapy during radiotherapy. In our study, since there will be no chemotherapy given during the preoperative setting, the administration of adjuvant chemotherapy postoperatively is highly recommended.
