4045 Background: Preoperative CRT with irinotecan and capecitabine is effective and safe in rectal cancer. Cetuximab, an EGFR- targeted agent, is synergistic with chemotherapy and radiotherapy. We conducted this study to determine efficacy and safety of cetuximab, irinotecan, and capecitabine as a combined preoperative CRT in patients with locally advanced resectable rectal cancer. Methods: This is a non-randomized, open-label, multicenter phase II study with cetuximab 400mg/m2 on D-6 (1 week before radiation) followed by cetuximab 250mg/m2 and irinotecan 40mg/m2 once a week (D1, 8, 15, 22, & 29) and capecitabine 1650mg/m2/day for weekdays only during radiation. Radiotherapy was given to a total dose of 50.4 Gy/28 fractions starting on D1. Main eligibility criteria were histologically proven rectal adenocarcinoma; T3–4 lesions; age 18 - 75 years; ECOG PS 0 - 2; no prior chemotherapy or EGFR targeted therapy. Total mesorectal excision was planned to be performed 4–8 weeks after completion of CRT. Results: Between May 2006 and Dec 2006, 40 patients were enrolled; median age 56.5 years (34 - 72); M/F 32/8; PS 0–1/2 38/2; cT3/T4 36/4; cN0/N+ 8/32; median tumor location from anal verge 5.5cm (0 - 8.0); moderately-differentiated adenocarcinoma 29. At present, 21 patients completed preoperative CRT and were evaluable for toxicity. Grade 3/4 toxicities included leucopenia (2, 9.5%), neutropenia (1, 4.8%), anemia (1, 4.8%) and diarrhea (1, 4.8%). Grade 2 hypersensitivity reactions and skin rashes were observed in 2 (9.5%) and 9 patients (42.9%), respectively and no grade >1 hand-foot syndrome was observed. Of 10 patients who underwent surgery (all R0 resection) till now, 9 were treated with sphincter saving procedure. Pathologic T0 and N0 were observed in 3 and 7 patients, respectively. Pathologic complete responses were observed in 2 patients and another 2 patients had only minimal microscopic residual tumor. Conclusions: Preoperative CRT with cetuximab, irinotecan and capecitabine showed promising preliminary pathologic responses with mild toxicity profiles. Study enrollment has now been completed and further results of efficacy and safety will be presented. No significant financial relationships to disclose.

e15501 Background: Concomitant radiochemotherapy is the standard treatment of locally advanced epidermoid anal canal carcinoma (EACC) but conventional radiotherapy (RT) frequently induces significant non-hematological toxicities, resulting in long treatment breaks. Given the numerous anatomic pelvic structures, EACC has become of interest for Intensity-Modulated Radiation Therapy (IMRT) despite the induced cutaneous toxicities responsible for RT breaks. Given the deleterious effect of treatment duration on local control and survival in other epidermoid cancers, continuous IMRT is challenging to control EACC. Several SIB-IMRT schedules provided similar results with moderate doses and schedules delivering higher doses with short breaks. Yet, standard SIB-IMRT schedule in EACC still not exists. We propose to concomitantly assess the safety and efficacy of continuous SIB-IMRT without planned breaks and concurrent chemotherapy (CT) to improve the treatment of locally advanced EACC by reducing the proportion of patients (pts) requiring RT breaks for toxicities. Methods: The CANAL-IMRT-01 phase 2 trial (NCT02701088) targets pts with histologically proven EACC candidate for concomitant RT of pelvic and inguinal nodes plus CT. Applying a two-step Bryant & Day design, the main criterion is based on both efficacy and safety. Efficacy is defined as the proportion of pts alive with no local disease progression 3 months after the end of IMRT; safety is defined as the proportion of pts with no RT breaks required by grade ≥3 toxicities. Assuming the unacceptable and acceptable proportions of pts without toxicity requiring IMRT break are 60 and 80% respectively, the unacceptable and acceptable 3-month-progression-free-survival are 80 and 90%, 14 assessable pts at first step and 46 in the second are required (alpha risk 5%, 90% power). To anticipate a 10% drop out rate, 16 pts were needed in first step, with ≥11 objective local responses and ≤6 toxicity-induced IMRT breaks to pursue. Treatment consists in 50 days of concomitant CT (2 cycles of 5FU and Mitomycin-C) and SIB-IMRT delivered by helical tomotherapy: 61.2Gy/1.7Gy to the primary tumor, 57.6Gy/1.6Gy to involved nodes, and 54/1.5Gy to elective pelvic lymph nodes. Results: From December 2015 to June 2017, 16 pts were enrolled: 11 female (73%), median age 62 [55-66]. 15 pts were assessable for efficacy and safety. All 15 pts had a 3-month locoregional response (12 complete responses, 3 partial responses). SIB-IMRT breaks were required by toxicities for 4 out of 15 pts: G1 radiodermitis, G2 inguinal and epithelitis, G1 fever, G3 anorexia and vertigo. Conclusions: The planned interim analysis of continuous SIB-IMRT plus CT allowed pursuing this phase 2 trial to assess the relevance of such schedule for locally advanced ASCC. Enrolment is still ongoing. Clinical trial information: NCT02701088.
