A Prospective Real-World Observational Study of Intratumoral Oncolytic Virus Injection Combined With Immune Checkpoint Inhibitors for Metastatic Tumors (Colorectal Cancer, Gastric Cancer, and Hepatocellular Carcinoma)
The goal of this single-arm, open-label, prospective clinical trial is to evaluate the safety, feasibility, and preliminary antitumor activity of intratumoral oncolytic virus (H101, recombinant human type 5 adenovirus) combined with immune checkpoint inhibitors (ICIs), and to explore the dynamic remodeling of the tumor immune microenvironment and potential predictive biomarkers, …
Study of BPI-572270 in Patients With Advanced Solid Tumors Harboring Specific Mutations in RAS
Evaluate the safety and tolerability of BPI-572270 in adult patients with specific RAS mutant advanced solid tumors.
Ultrasound and Photoacoustic Imaging for Enhanced Differential Diagnosis of Rectal Cancer
The purpose of this study is to demonstrate the functionality of a novel endorectal photoacoustic ultrasound imaging modality in humans with rectal cancer. The study involves testing a previously developed endorectal device to determine its ability to accurately assess rectal tumor response to preoperative treatment. Investigators hypothesize that a co-registered …
ctDNA-guided Adjuvant Chemotherapy in Liver Metastasis of Colorectal Cancer
The goal of this clinical trial is to compare in resectable colorectal cancer liver metastasis patients.The main question it aims to answer is whether the 3-year progression-free survival rate (PFS) of "watching and waiting" is non-inferior to adjuvant chemotherapy in postoperative ctDNA-negative resectable colorectal cancer liver metastasis patients.Participants will undergo …
Metarrestin (ML-246) in Subjects With Metastatic Solid Tumors
Background Metastasis is the spread of cancer from one organ to a nonadjacent organ. It causes 90% of cancer deaths. No treatment specifically prevents or reduces metastasis. Researchers hope a new drug can help. It stops cancer cells from growing and spreading further and possibly shrink cancer lesions in distant …
PITCHER (Peritoneal Carcinomatosis Heterogeneity)
How epigenetic deregulation affects gene expression patterns in subclones of the same tumor is poorly known. Peritoneal Carcinomatosis (PC) is a condition in which multiple metastases of the same abdominal tumor develop in the peritoneal cavity and intra-peritoneal organs, thus defining different ecosystems of the same cancer. PITCHER addresses the …
Postoperation Maintenance Therapy for Resectable Liver Metastases of Colorectal Cancer Guided by ctDNA
The goal of this clinical trial is to compare in resectable liver metastases colorectal cancer patients.The main question it aims to answer is to investigate whether the progression-free survival (PFS) of resectable colorectal liver metastasis (CRLM) patients with positive ctDNA after surgery is superior with the combination of adjuvant chemotherapy …
Comparing Polypropylene Mesh and "Small Bites" Technique in Emergency Colorectal Surgery's Midline Laparotomy Closure. Study for Incisional Hernia Prevention.
The 2023 World Journal of Emergency Surgery guidelines couldn't provide a recommendation for emergency abdominal wall closure due to insufficient consensus (\>80% required). Available evidence, predominantly retrospective and heterogeneous, lacks differentiation between urgent and elective colorectal surgeries. Therefore, we advocate for a study comparing laparotomy closures in emergency colorectal surgery …
OPTIMIzation of Treatment SElection and Follow up in Oligometastatic Colorectal Cancer
A study investigating if analysis of circulating tumor DNA (ctDNA) can guide adjuvant treatment in patients with advanced colorectal cancer (CRC)
Adaptive Anastomosis for Anterior Resection in Sigmoid and Proximal Rectal Cancer or Premalignant Lesions
Background: Anastomotic leakage (AL) after colorectal surgery remains a significant challenge, associated with increased morbidity, mortality, poor oncological outcomes, and reduced quality of life. Despite surgical advances, AL rates for colorectal procedures continue to range from 3% to 25%, especially in distal anastomoses. The commonly used cross-stapled circular anastomosis for …
