Cytoreductive surgery

Cytoreductive surgery (CRS) is a surgical procedure aimed at reducing the number of cancer cells in the body. This is achieved by removing or destroying metastases (cancerous growths that have spread from the primary site to other parts of the body) with the goal of improving symptoms and prolonging survival. CRS is often used in conjunction with hyperthermic intraperitoneal chemotherapy (HIPEC), a treatment that involves the direct application of heated chemotherapy drugs into the abdominal cavity immediately following surgery.

Indications

Cytoreductive surgery is primarily indicated for patients with certain types of cancer that have spread within the abdominal cavity, such as ovarian cancer, colorectal cancer, mesothelioma, and peritoneal carcinomatosis. The decision to proceed with CRS depends on various factors, including the patient's overall health, the extent of cancer spread, and the likelihood that a significant proportion of the tumor mass can be removed.

Procedure

The procedure involves the surgical removal of visible tumor masses from the abdominal cavity. This may include the resection of affected organs or tissues, such as the ovaries, uterus, parts of the intestine, or the peritoneum (the lining of the abdominal cavity). The goal is to leave behind no visible tumors or, at the very least, tumors smaller than 1 mm in diameter, as these can potentially be treated with chemotherapy.

Following the cytoreductive surgery, HIPEC may be administered. This involves circulating a heated chemotherapy solution within the abdominal cavity for a specific period, usually up to 90 minutes. The heat and direct contact with the chemotherapy agents aim to kill any remaining cancer cells.

Benefits and Risks

The primary benefit of CRS, especially when combined with HIPEC, is the potential for significantly improved survival rates and quality of life for patients with advanced abdominal cancers. However, the procedure is complex and carries a risk of complications, such as infections, bleeding, and issues related to the removal of significant amounts of tissue or organs.

Recovery

Recovery from cytoreductive surgery can be lengthy and challenging, requiring a stay in the intensive care unit (ICU) and a longer overall hospital stay. Patients may need to undergo physical therapy and will likely require assistance during the initial recovery period. The success of the surgery, in terms of cancer control and improvement in symptoms, will be monitored through regular follow-ups with the healthcare team.

Conclusion

Cytoreductive surgery, particularly when combined with HIPEC, represents a significant advancement in the treatment of certain abdominal cancers. While it offers hope for improved outcomes in selected patients, the complexity and risks associated with the procedure necessitate careful patient selection and management by an experienced multidisciplinary team.
