Brief Summary

Anal canal carcinoma (ACC) represents 1.2% of digestive cancers. Its incidence is increasing. As epidermoid ACC (95% of ACC) are particularly sensitive to radio and chemotherapy, concomitant radio-chemotherapy is the standard treatment of locally advanced ACC, with proven efficacy on locoregional control, anal sphincter preservation, progression-free survival and complete response rate higher than 80%.

Nevertheless, conventional radiotherapy frequently induces significant non-haematological toxicities requiring treatment interruptions. Thus, treatment usually includes a chemotherapy (5-Fluorouracil and Mitomycine-C) and 25 fractions of 1.8 Gy followed by a planned 1-week (or more) interruption and a boost, for a total 54-60 Gy radiation dose over 9 weeks.

Considering the numerous anatomic pelvic structures, ACC has become a localisation of interest for Intensity-Modulated Radiation Therapy (IMRT) associated with less toxicity.

However, IMRT induces grade≥3 cutaneous toxicities requiring irradiation breaks. Dose escalade did not show its interest: 60 Grays remains the standard.

Assuming the deleterious effect of increased overall treatment time on local control and survival in head-and-neck and cervical cancers and the epidermoid histology of ACC, the benefit of no irradiation break on ACC tumour control is of interest.

IMRT offers the possibility to deliver different doses to different target volumes simultaneously by altered fractionation schedule like SIB-IMRT (simultaneously integrated boost-IMRT). Several SIB-IMRT schedules have been retrospectively evaluated. Similar results were observed with moderate doses and schedules delivering higher doses with short interruptions. Nevertheless, standard SIB-IMRT schedule in ACC still not exist.

Intervention

• Drug: 5Fluorouracile and Mitomycin-C
  All the patients will receive radiochemotherapy with two cycles of 5FU (1,000 mg/m²/d with 96-h infusion, days 1-5 and 29-33 of SIB-IMRT) and Mitomycin-C (10 mg/m², days 1 and 29).

  SIB-IMRT schedule of 61.2 Gy/1.7 Gy to the primary tumor, 57.60 Gy / 1.6 Gy to involved nodes, and 54 / 1.5 Gy to elective pelvic lymph nodes.
