A Prospective Study of a Subharmonic-Aided Pressure Estimate Technology for Early Prediction of Response to Systemic Therapy in Colorectal Cancer Liver Metastases

Colorectal cancer is a common type of cancer that often spreads to the liver. When cancer spreads to the liver, treatment becomes very difficult. Many patients will undergo chemotherapy to shrink the tumor. Currently, doctors use CT or MRI scans to assess the effect of chemotherapy, but these examinations usually take about 2 months to show changes in the size of the tumor. The purpose of this study is to test whether a special type of ultrasound technology called "contrast-enhanced subharmonic ultrasound" can help doctors determine earlier whether chemotherapy is effective compared to conventional scans. This ultrasound detection does not use radiation and can display the blood perfusion status inside liver tumors. We will observe the changes in blood flow perfusion inside the tumor before the start of treatment and after 1-2 chemotherapy cycles to see if these changes can predict whether chemotherapy will be effective in the future. If this test is effective, it will help doctors adjust the treatment plan more quickly, which may improve the treatment effect for colon cancer patients whose cancer cells have spread to the liver, and also help identify patients who are not responding to chemotherapy as early as possible, reducing the side effects and economic burden of patients.

Health Related Quality of Life Following Hepatectomy for Colorectal Liver Metastasis: Global and Disease Specific Changes Over Time

This study is being done to learn more about health related quality of life factors in people having surgery for colorectal liver metastasis. The investigators will look at how these factors may change over time. The information gained from this study will help the investigators to understand the long-term effects that cancer treatments have on the health related quality of life of patients. This information is of high value and will help doctors talk to patients about the possible effects of their operations. While many patients live a long time after such operations, the studies that have been done do not tell the full story of what patients go through after surgery. This study will help us to understand cancer treatment from the patient's perspective. It will also help cancer patients make better decisions about their treatment options and will help them know what to expect after the operation.

Comparison of the Resection Site Order in Simultaneous Approach of Colorectal Liver Metastasis

Colorectal cancer frequently presents with liver metastases, and complete removal of both primary and liver tumors can significantly improve survival. Simultaneous resection (SA) of the colon and liver is increasingly used and is considered safe when minor liver resections are performed, offering advantages such as shorter hospitalization, fewer complications, and faster chemotherapy initiation. However, the best sequence of resection, liver-first or colon-first, remains uncertain, as each has potential benefits and drawbacks, particularly regarding anastomotic healing. Minimally invasive approaches to SA show similar outcomes to open surgery, though limited data suggest that resection order may affect blood loss.

Anatomical Resection of Liver MetAstases iN patIents With RAS-mutated Colorectal Cancer

the ARMANI trial will test the hypothesis, if an anatomic resection (AR) improves long-term outcome vs. a non-anatomical resection (NAR) in patients undergoing surgery for RAS-mutated colorectal liver metastasis (CRLM).
