Advanced Colorectal Adenocarcinoma

This phase II trial tests how well giving botensilimab and balstilimab prior or to surgery (neoadjuvent) works for the treatment of colorectal cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and that can be removed by surgery (resectable) colorectal cancer. Immunotherapy with monoclonal antibodies, such as botensilimab and balstilimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving botensilimab and balstilimab before surgery may make the tumor smaller. Giving neoadjuvant botensilimab and balstilimab may be effective for the treatment of advanced resectable colorectal cancer.

The goal of this clinical trial is to test the efficacy a new psychosocial symptom management intervention called ENGAGE for patients with Stage IV breast, prostate, lung, or colorectal cancer. Participants will be randomized to ENGAGE or a Supportive Care intervention. Patient-reported outcomes will be assessed at baseline, 2 months, and 4 months.

This is a prospective, single-arm clinical study designed to evaluate the 6-month progression-free survival rate (6-month PFS rate) of Doxorubicin liposome combined with CapOX and Bevacizumab regimen as first-line treatment for advanced colorectal adenocarcinoma with SMAD4R361H/C mutation. The study plans to recruit 13 patients. After receiving 8 cycles of induction therapy, patients whose efficacy is evaluated as complete response (CR), partial response (PR), or stable disease (SD) (according to RECIST 1.1) will enter maintenance therapy.
