Although guidelines on the management of mTOR inhibitor-associated DIP in cancer patients have been published, these do not always concur or cover all management aspects. Education of patients and healthcare professionals is a key component in managing mTOR inhibitor therapy; assessing the history of pulmonary conditions before the initiation of such a therapy is also essential. Updated diagnostic criteria for pneumonitis might improve our knowledge in the future.
Objective To report a prospective phase II study of patients with disseminated peritoneal carcinomatosis and symptomatic disease, in whom the peritoneal metastases were resected. Patients and methods From 1995From to 1999 (20 men and 12 women, median age 56 years, range 32-75) with peritoneal carcinomatosis were enrolled in the trial. Pain and ascites were determined according to the National Cancer Institute score/criteria, and performance scored according to the World Health Organisation criteria. Results All patients had intraperitoneal disseminated malignancies with clinically evident ascites, and presented with abdominal pain. The median (range) operative duration was 2.9 (1-5.5) h and the hospital stay 25 (10-44) days, with no deaths at 30 days. The ascites was completely cured in 25 of the 32 patients, pain relieved in 28 and the performance score improved in 25. The median survival time was 1 year; the 1-and 2-year survival rates were 45% and 38%, respectively. Patients with residual metastases after incomplete resection had a significantly worse prognosis, but the prognosis was significantly better in those with a low tumour burden. Conclusions Peritoneal carcinomatosis is treatable; radical peritonectomy improves the performance score in selected patients with cancer-related ascites and/or pain, and is now the standard approach in the authors' Cancer Centre.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
