Filter by:The hereby proposed ACO/ARO/AIO-18.1 randomized trial aims to directly compare the newly established TNT concepts applying either short-course RT according to RAPIDO, or CRT according to CAO/ARO/AIO-04/-12, both followed by consolidation chemotherapy, and surgery or a watch&wait (W&W) approach for patients with clinical complete response (cCR). The ACO/ARO/AIO-18.1 study incorporates several novel and innovative aspects to further optimize multimodal rectal cancer treatment, partly established by our preceding CAO/ARO/AIO-04 and CAO/ARO/AIO-12 randomized trials: (1) patient selection is based on strict, quality controlled MRI features of intermediate and high-risk characteristics (and, thus, complementary to our ACO/ARO/AIO-18.2 trial in "low-risk" rectal cancer), (2) the CRT regimens incorporates 5-FU/oxaliplatin with doses and intensities shown to be effective and well-tolerated without compromising treatment compliance in CAO/ARO/AIO-04, (3) the sequence of CRT, CT, and surgery/W&W adopts the TNT approach as established by our CAO/ARO/AIO-12 and OPRA trial, (4) surgical stratification allows for W&W management for strictly selected patients with clinical complete response (cCR). Thus, we hypothesize that TNT with 5-FU/oxaliplatin-CRT followed by consolidation chemotherapy may increase organ preservation while maintaining DFS as compared to RAPIDO-like short-course RT followed by consolidation chemotherapy.
This is a open-label, single-arm study to investigate the safety and efficacy of total neoadjuvant treatment (TNT) in patients with locally advanced resectable rectal cancer.
A number of pilot studies had shown high rate of complete resection after neoadjuvant chemotherapy alone for local advanced rectal cancer(LARC), but they did not increase the ratio of pathological complete response (pCR) which was associated with improvement of overall survival (OS). On the other hand,some clinical trials show that triple active cytotoxic agents (Fluorouracil, Oxaliplatin, Irinotecan, FOLFOXIRI) combined with cetuximab for EGFR wild type metastatic colorectal cancer had more effective than double agents.Therefore,a hypothesis is the FOLFOXIRI+Cetuximab as the neoadjuvant chemotherapy regimen might improve the patient's ratio of pCR.
