Abstract

Opinion statement: Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm that rapidly spreads within the confines of the abdominal cavity to involve most accessible peritoneal and omental surfaces. Current treatment options are unsatisfactory, and new approaches are needed. Recent publications have reported improved survival with an intensive loco-regional treatment strategy including cytoreductive surgery (CRS) along with hyperthermic intraperitoneal chemotherapy (HIPEC). We have noted at our institution prolonged survival in selected patients after intensive multimodality treatment. Our most recently reported trial included initial laparatomy with omentectomy, resection of peritoneal implants, and placement of bilateral peritoneal Portacath; repeated courses of intraperitoneal chemotherapy with doxorubicin, cisplatin, and interferon gamma; second-look laparotomy; and intraoperative hyperthermic perfusion with mitomycin and cisplatin, followed by whole abdominal radiation. To date there have been no universally accepted treatments for MPM. Unless referred to a specialty center, patients are routinely treated with pemetrexed and cisplatin which has been shown to increase survival in pleural mesothelioma.

Glossary

resection

surgery to remove part or all of an organ or other structure.

oncology

(on-call-o-jee) the branch of medicine concerned with the diagnosis and treatment of cancer.

neoplasm

(nee-o-plas-um) an abnormal growth (tumor) that starts from a single altered cell; a neoplasm may be benign or malignant. Cancer is a malignant neoplasm.

interferon

(in-ter-fear-on) a protein produced by cells. Interferon helps regulate the body's immune system, boosting activity when a threat, such as a virus, is found. Scientists have learned that interferon helps fight against cancer, so it is used to treat some types of cancer.

chemotherapy

(key-mo-THER-uh-pee) treatment with drugs to destroy cancer cells. Chemotherapy is often used with surgery or radiation to treat cancer when the cancer has spread, when it has come back (recurred), or when there is a strong chance that it could recur.

bilateral

(bi-lat-er-ul) on both sides of the body; for example, bilateral breast cancer is cancer in both breasts.

mesothelioma

a tumor derived from mesothelial tissue, such as the peritoneum (lining the abdomen) or pleura (lining the lungs). More on mesothelioma.

peritoneal

(pair-uh-tuh-nee-al) the serous membrane that lines the cavity of the abdomen. (More on Peritoneal Mesothelioma.)

pemetrexed

chemotheraputic agent that interferes with a crucial process that allows cancer cells to reproduce and spread. Specifically, pemetrexed stops the production of three enzymes that are required to feed the cancer cell. Often used in combination with cisplatin. Marketed under the name ALIMTA. See: Alimta.

intraperitoneal chemotherapy

(IPC) a form of regional chemotherapy; the flooding of the abdominal cavity with chemotheraputic drugs to target the cancer cells directly. It is sometimes heated to improve absorption of the anticancer drugs by the cancerous cells and because heat itself can kill cancer cells.
