HIPEC, or Hyperthermic Intraperitoneal Chemotherapy, is a revolutionary procedure designed to combat the spread of cancer beyond its original site. It works by delivering a concentrated dose of chemotherapy directly into the abdominal cavity, aiming to target and treat microscopic cancerous cells lurking within the abdomen. At the heart of this procedure lies the peritoneum, a serous membrane lining the abdominal cavity, which plays a pivotal role in the treatment of abdominal cancers. This innovative treatment method, known as hyperthermic intraperitoneal chemotherapy HIPEC, has shown promising results in the fight against cancer.

This technique is particularly effective in managing metastatic cancers and cancers originating in the abdominal region, such as peritoneal surface malignancies (PSM) like colon cancer, appendix cancer, mesothelioma cancer, and adrenal cancer. The effectiveness of HIPEC surgery is attributed to its method of administering high chemotherapy doses directly into the abdomen. This has the potential to improve long-term outcomes and offer hope for patients grappling with advanced stages of the disease.

The Mechanics of HIPEC Therapy

Heated chemotherapy perfusion process

HIPEC treatment involves two steps: cytoreductive surgery and heated chemotherapy perfusion. This combination plays a significant role in treating cancer more effectively by first removing visible tumors and diseased tissue from the abdomen, and then circulating heated chemotherapy drugs to target any residual cancer cells.

Cytoreductive surgery alone is not considered comprehensive for PSM treatment due to its inability to eradicate all cancer cells. This is attributed to the diffuse nature of the disease. As a result, adjunctive heated chemotherapy is necessary to target any residual microscopic remnants, effectively killing cancer cells.

Integrating cytoreductive surgery with HIPEC therapy boosts treatment outcomes, providing patients with a beacon of hope in their battle against cancer.

Cytoreductive Surgery Explained

The HIPEC process starts with cytoreductive surgery. It is an intensive procedure focused on eliminating visible tumors and diseased tissue in the abdomen, aiming to eradicate all visible signs of cancer before the administration of heated chemotherapy. This surgical process encompasses a range of peritonectomy procedures aimed at achieving complete removal of all macroscopic disease, particularly in cases of metastatic cancer.

This procedure is often required in the treatment of cancers affecting the peritoneal cavity, such as:

  • Peritoneal carcinomatosis of colorectal

  • Ovarian

  • Colon

  • Gastric

  • Appendix cancers

In most cases, cytoreductive surgery is combined with HIPEC as an alternative to systemic chemotherapy, which can provide a more targeted approach to cancer treatment and potentially improve patient outcomes.

Perfusion of Heated Chemotherapy
