This phase Ib/II trial studies how well anti-PD-L1/TGFbetaRII fusion protein M7824 (M7824) works in treating patients with colorectal cancer (or with other solid tumors with microsatellite instability) that has spread to other places in the body or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as M7824, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
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.
This randomized phase II trial studies how well trastuzumab and pertuzumab work compared to cetuximab and irinotecan hydrochloride in treating patients with HER2/neu amplified colorectal cancer that has spread from where it started to other places in the body and cannot be removed by surgery. Monoclonal antibodies, such as trastuzumab and pertuzumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cetuximab and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving trastuzumab and pertuzumab may work better compared to cetuximab and irinotecan hydrochloride in treating patients with colorectal cancer.
Project HERO is a 12-week study of the efficacy of Body Mind Training (BMT) for reducing fatigue in male cancer survivors. This 3-arm randomized clinical trial will examine inflammatory biology and selected gene-expression pathways that are hypothesized to contribute to the intervention's effect.
All the preoperative biopsies of patients suffering colorectal cancer (CRC) will be immunohistochemically stained with a pancytokeratin marker to detect Tumor buds. then, the intratumoral buds (ITB) in the densest Region of Tumor buds, namely the "hot spot" will be counted. Subsequently, the probability of N stage (lymphnodes), M stage (metastases) and disease free survival (DFS) will be calculated based on an existing logistic Regression model already developed by our previous retrospective work. Additionally, a Standardisation of ITB using a well- established Software will develop an algorithm which will help to eliminate inter- observer variability of Tumor budding Counts.
This study is a prospective, monocentric study whose aim is to assess the quality of life for patients who underwent a coloanal continuity reconstruction and to understand the functional issues they encounter. This will potentially provide predictive factors identification of bad functional outcomes allowing to guide future decisions. Also, it will allow patients to have a reinforced follow-up during the year after the reconstruction.
This randomized pilot clinical trial studies health care coach support in reducing acute care use and cost in patients with cancer. Health care coach support may help cancer patients to make decisions about their care that matches what is important to them with symptom management.
Radical rectal cancer resection, namely total mesorectal excision (TME), is the cornerstone of the treatment of resectable rectal cancer. In combination with chemotherapy and radiation treatment (CRT), complete TME with negative resection margins is associated with sustained local and systemic control even in locally advanced disease. Over the last 2 decades, laparoscopic and robotic techniques have been increasingly adopted due to reduced surgical trauma and faster patient recovery. Yet, both approaches are associated with equivalent postoperative morbidity and disturbances in sexual, urinary and defecatory function relative to open TME. Furthermore, laparoscopic and robotic TME remain associated with substantial conversion rates and variable rates of TME completeness as a result of the procedural difficulties reaching the low rectum from the abdominal approach. Transanal TME (taTME) with laparoscopic assistance was developed to facilitate completion of TME using a primary transanal endoscopic approach. Transanal TME uses a "bottom-up approach" to overcome the technical difficulties of low pelvic dissection using an abdominal approach. Published results from single-center taTME series and an international registry suggest the short-term procedural and oncologic safety of this approach in resectable rectal cancer. No multicenter phase II study has yet been conducted to validate the procedural safety, functional outcomes or long-term oncologic outcomes of this approach. Study Design: This is a 5-year phase II multicenter single-arm study to evaluate the safety and efficacy of low anterior resection (LAR) with taTME using laparoscopic or robotic assistance in 100 eligible subjects with resectable rectal cancer. Hypothesis: taTME is non-inferior to standard LAR with respect to the quality of the TME achieved.
The study has a phase Ib and a phase II part. The phase Ib part of the study aims to determine the safety and tolerance of administration at a fixed dosing of 1200 mg / 3 weeks, concomitantly to the standard preoperative radio-chemotherapy. The phase II part of the study aims to explore efficacy of atezolizumab in combination with the standard preoperative chemo/radiotherapy in stage II and III rectal cancers.
