Because of the absence of symptoms in early natural history of peritoneal mesothelioma, a large majority of patients are first diagnosed with a large volume of spreading disease diffuses through the abdomen and pelvis. The disease accumulates in the largest quantity at the sites of the reabsorption of peritoneal fluid and sites depends on gravity. The small intestine and mesenteries surfaces are not spared by the implants mesothelioma in appendiceal mucinous tumors.
Promising results of treatment from a new strategy: more cytoreductive surgery perioperative intraperitoneal chemotherapy: Four groups have reported about 300 malignant peritoneal mesothelioma patients. The National Cancer Institute in Bethesda, MD, The Washington Cancer Institute in Washington, DC, The Columbia mesothelioma Center in New York and the National Cancer Institute in Milan, Italy. Each group reported their experience with between 50 and 100 patients. Under the current pay all groups report a median survival of 5 years or more. The median survival in the past was about 1 year (see tables 1 and 2). Because of this apparent improvement in survival with a new treatment strategy, it became the standard of care for these patients.
1. On neoadjuvant chemotherapy: A first possible treatment following the diagnosis of peritoneal mesothelioma is systemic chemotherapy with pemetrexed and cisplatin chemotherapy. The protocol was launched at the National Cancer Institute of Italy and was not regarded as beneficial for these patients. However, anecdotal and beneficial responses were reported. The chemotherapy which has about a 30% response rate from May to be more value in a maximum after adjuvant chemotherapy and mechanical cytoreduction peritoneal mesothelioma occurred. Neoadjuvant systemic chemotherapy was considered appropriate for biphasic sarcomatoid or malignant peritoneal mesothelioma.
2. Regarding the selection of patients using the histological type of mesothelioma: All groups agree that patients with sarcomatoid biphasic or peritoneal mesothelioma do not show great benefits from this treatment. Mr. Chabot and mesothelioma Columbia Centre agrees with the limited benefits but called for continued aggressive approach with patients to have found biphasic mesothelioma. The Washington Hospital Center group also suggested that patients with grade IV conclusions in the nucleus demonstrate a poor outcome with combination therapy. They suggested that these patients should also have neoadjuvant chemotherapy prior to the opening of the combined approach. In patients who show a reduction in the volume of the disease and symptomatic improvement, perioperative cytoreductive surgery with chemotherapy intraperitoneal May be taken into consideration. In patients who did not respond to the first line of chemotherapy, then the second-line chemotherapy with Gemzar may be recommended. In patients not responding to any of these systemic chemotherapy treatments, the best palliative care is offered.
3. Regarding cytoreductive surgery: Cytoreductive surgery with peritonectomy is the first stage of treatment of all four institutions. However, the extent of the surgery varies considerably among the four groups. Perhaps the most conservative initial effort was proposed by Mr. Chabot. His initial treatment is a minimum debulking, usually only greater omentectomy and remove a large tumor nodules. Then intraperitoneal ports are placed and the patient receives chemotherapy interval intraperitoneal using doxorubicin and cisplatin or mitomycin C and cisplatin. In his new protocol, intraperitoneal heated chemotherapy will be used during this first event.
Mr. Pingpank the National Cancer Institute, USA, advocated a visceral household cytoreduction. In this approach large cancer nodules would be deleted, peritonectomy be done, however, the complete elimination of the disease would not be attempted.
At the National Cancer Institute of Italy and the Washington Hospital Center, complete cytoreduction has been tried to no visible sign of the disease. Peritonectomy procedures right and left hemidiaphragm and pelvis are standard of care in this group of patients. Also, visceral resection of the colon right or left of the colon, if it leads to a substantial reduction in the volume of the disease, is recommended.
The morbidity and mortality combined treatment is considered acceptable in treatment centres dedicated (Table 3).
4. Regarding the period of intraperitoneal chemotherapy: All groups have argued for a hyperthermia intraperitoneal cisplatin-based chemotherapy. The doses were different in the four institutions. The heat, approximately 42.5 ยบ C, is the same in all schools. The drugs combined with cisplatin and doxorubicin were mitomycin C. At the National Cancer Institute, USA, high-dose cisplatin with systemic thiosulfate was used.
