This article demonstrates the experience of successful treatment of a patient with locally advanced rectal cancer, who received a combined treatment with a non-standard course of chemoradiotherapy in hypofractionation mode according to a prolonged program. After the end of a course of chemoradiation received the complete clinical response of the tumor.

Locally Advanced Colorectal Cancer

The article describes the experience of using ther-mochioradiotherapy in the combined treatment of distal locally advanced colorectal cancer, as well as comparing the effectiveness of treatment with chemoradiation therapy. The use of the proposed method as a component of the combined treatment of patients with rectal cancer allowed to increase the percentage of organ-preserving operations. As a result of thermochemotherapy, the prevalence of the primary tumor was significantly reduced, as a result of which the number of sphincter-bearing operations was reduced by almost 2 times (p

TPS816 Background: Preoperative 5-Fluorouracil based chemoradiotherapy is the standard of treatment for locally advanced rectal cancer. About 15% to 18% of patients would achieve pathologic complete response (pCR) after 5-Fluorouracil based chemoradiation. And the survival outcome of patients with pCR was much better than that of non-pCR. In our previous FOWARC study, in the group of preoperative systemic chemotherapy with mFOLFOX6 combined with radiation, the pCR rate was up to 27.5%. In another study, adding mFOLFOX6 after neoadjuvant chemo radiation in locally advanced rectal cancer improve the pCR rate to 38%. This phase II study aimed to explore whether totally neoadjuvant chemoradiation therapy with mFOLFOX6 could further improve the pCR rate in locally advanced rectal cancer. Methods: The primary endpoint is the pathologic complete response rate (pCR).The secondary endpoint included 3-year disease free survival rate, 3-year local recurrence rate, and safety. We hypothesized that totally neoadjuvant chemoradiation therapy with mFOLFOX6 could improve the pCR rate from 18% to 45% with 5% type I error and 80% power. Fifty patients met inclusion criteria will be enrolled in the trial. All patients will receive long term radiation for 25 times and 50Gy before surgery. Four cycles of mFOLFOX6 would be performed every 2 weeks during radiotherapy, and another 4-6 cycles would be added after radiotherapy and before operation. Totally, the patients will receive 8-10 cycles of chemotherapy before surgery. MRI of the pelvic will be performed every 4 cycles of the therapy to assess clinical response. Then the patient will receive total mesorectal excision at least 8 weeks after radiotherapy. The post-operative chemotherapy will be omitted and all the patients go to surveillance. Clinical trial information: NCT02887313.
