Filter by:This phase I/II trial studies the side effects and how well fluorescence image guided surgery followed by intraoperative photodynamic therapy for improving local tumor control in patients with colorectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or that has come back after a period of improvement (recurrent). Fluorescence image guided surgery uses a drug named aminolevulinic acid hydrochloride. Aminolevulinic acid hydrochloride is a photosensitizing agent, meaning that is activated by light and, is converted to another drug in cancer cells more than in normal cells. The converted drug emits fluorescence red light when activated with low power blue light. It is used to assist the surgeon to see cancer cells and small cancerous tissue that may have been missed during routine surgery. In addition to emitting fluorescence light, the converted drug in the cancer cells and tissue can be activated with red laser light to kill cancer cells. This procedure is called photodynamic therapy (PDT). Performing fluorescence image guided surgery followed by intraoperative photodynamic therapy after the surgical removal of the colorectal tumor before the surgical site will be closed may be effective and improve outcomes in patients with locally advanced or recurrent colorectal cancer.
Researchers collect specimens from advanced or recurrent colorectal cancer (CRC) patients to conduct molecular profiling and establish tumor organoids (PDOs)/ patient-derived xenografts (PDXs). The aim of this study is to identify clinical actionable targets and predict in vivo response of the tumor to targeted drugs by using PDOs/ PDXs. And the above-mentioned studies will provide the patients with potential personalized cancer treatment options.
The phase II trial tests whether pembrolizumab and dendritic cell-based treatment works to shrink tumors in patients with colorectal cancer that does not respond to treatment (refractory). Pembrolizumab, also referred to as an immune checkpoint inhibitor drug, works by targeting molecules that act as a check and balance system for immune responses. Immune checkpoint inhibitor drugs are designed to either "unleash" or "enhance" the cancer immune responses that already exist by either (1) blocking inhibitory molecules or by (2) activating stimulatory molecules. Dendritic cell-based treatment works by boosting the immune system (a system in our bodies that protects us against infection) to recognize and destroy the cancer cells. This investigational treatment targets cancer cells and is made from the patient's own blood cells. Giving pembrolizumab and dendritic cell-based treatment may help shrink tumors in patients with colorectal cancer.
This randomized controlled clinical phase II study was designed to compare the effect of rhTPO with rhIL-11 in improving thrombocytopenia in patients with recurrent colorectal cancer who underwent radiotherapy and with thrombocytopenia.
