Colon and Rectal Cancer

COLOFLOW is a prospective observational study investigating whether Laser Speckle Contrast Imaging (LSCI), a dye-free and objective perfusion imaging technique, corresponds with the currently used subjective assessment of indocyanine green (ICG) fluorescence during colorectal surgery. In approximately 30 patients undergoing elective colon or rectal resection with primary anastomosis, both imaging modalities will be performed intraoperatively. The surgeons will base their clinical decisions solely on standard ICG fluorescence imaging, while LSCI measurements are collected for research purposes and do not influence treatment. Postoperatively, quantitative ICG parameters will be analysed and compared with LSCI perfusion maps to determine whether objective ICG analysis improves agreement with LSCI over subjective interpretation alone. In addition, the study will evaluate the feasibility of using the PerfusiX-IGS LSCI system during open colorectal surgery and describe postoperative outcomes, including anastomotic leakage. The ultimate goal is to contribute to more objective and standardized perfusion assessment during colorectal surgery

This is a Phase 1 and Phase 2 study to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of INV-8989 in patients with advanced solid tumors harboring KRAS G12D mutations.

This study is being conducted to find out if treatment with gemcitabine, cisplatin, nab-paclitaxel, and cemiplimab can shrink previously inoperable tumors enough for surgery.

An experimental study through a randomized clinical trial, without blinding (for participants and the research team), with a control group (not subject to intervention) and an intervention group (subject to two text messages, an automated non-human call or a call made by the administrative assistant, and a phone call made by a physician).
