Protein abundance of drug transporters and drug-metabolizing enzymes in paired healthy and tumor tissue from colorectal cancer patients.
Int J Pharm

The widespread prevalence of colorectal cancer and its high mortality rate emphasize the urgent need for more effective therapies. When developing new drug products, a key aspect is ensuring that sufficiently high concentrations of the active drug are reached at the site of action. Drug transporters and drug-metabolizing enzymes can significantly influence the absorption and local accumulation of drugs in intestinal tissue.

Background: This study investigates the effectiveness of a three-dimensional reconstruction mathematical model (3D-IPR) for preoperative planning in locally advanced colon cancer (LACC) with threatened surgical margins. The objective was to evaluate the utility of a 3D-IPR surgical planner tool in cases of LACC with threatened surgical margins. Additionally, the study aims to compare the diagnostic accuracy of the 3D-IPR model against conventional CT scans in determining the infiltration of neighboring structures.

Dis Colon Rectum
November 2024
Department of Colon and Rectal Surgery, Memorial Sloan Kettering Cancer Center, New York.
Background: The watch-and-wait strategy provides an opportunity to pursue non-operative management in rectal cancer patients with clinical complete response after neoadjuvant therapy. The management of those with near complete response remains controversial.
Objective: We assessed the oncologic outcomes of patients managed by watch-and-wait versus total mesorectal excision according to clinical response to neoadjuvant therapy.
Anticancer effect of a single-chain variable fragment against pro-matrix metalloproteinase-7 in colon cancer.

Department of Life Sciences, Ewha Womans University, Seoul 03760, South Korea. Electronic address:
Disrupting the interaction between matrix metalloproteinase-7 (MMP-7) and syndecan-2 (SDC-2) can yield anticancer effects in colon cancer cells. Here, a single-chain variable fragment (scFv) targeting the pro-domain of MMP-7 was generated as a potential candidate anticancer agent. Among the generated scFvs, those designated 1B7 and 1C3 showed the strongest abilities to inhibit the ability of MMP-7 pro-domain to directly interact with SDC-2 in vitro and decrease the cancer activities of human HT29 colon adenocarcinoma cells.

Division of Pathology & Data Analytics, Leeds Institute of Medical Research, University of Leeds, UK.
Background: The FOxTROT trial has reported advantages of neoadjuvant chemotherapy (NAC) in locally advanced colon cancer (LACC). Here we present results of the embedded randomized phase II trial testing the addition of panitumumab to neoadjuvant FOLFOX compared with FOLFOX alone in RAS and BRAF-wild-type patients and with biomarker hyperselction.
Patients And Methods: Patients had operable, CT-predicted stage T3-4, N0-2, M0 colon adenocarcinoma.
