Background: Malignant peritoneal mesothelioma (MPM) is a rare and aggressive form of cancer arising from the peritoneum. The prognosis for MPM has historically been poor, and treatment options are limited. This study evaluated the impact of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) as a treatment modality for MPM.
Materials and methods: This retrospective analysis included 15 patients diagnosed with MPM between 2012 and 2023 at a tertiary referral cancer care center in North India. Patients underwent CRS followed by HIPEC. The study assessed outcomes based on overall survival (OS) and postoperative morbidity rates.
Results: Demographic analysis revealed a female preponderance (n = 9, 60%) and a majority of younger patients, 80% (n = 12) of whom were younger than the age of 50. The mean peritoneal cancer index (PCI) was 14.0, with 60% (n = 9) of patients having a PCI above the mean. The completeness of cytoreduction (CC) varied, with 40% (n = 6) achieving CC0, 33.33% (n = 5) CC1, and 26.67% (n = 4) CC2. Adjuvant chemotherapy was administered to 60% (n = 9) of the patients. The median follow-up period was 25 months, revealing an overall median survival of 27.0 months, with one- and three-year survival rates of 86.7% and 33.3%, respectively.
Conclusion: CRS combined with HIPEC is a viable and effective treatment option for patients with MPM and offers improved survival rates and an acceptable safety profile. These findings support the integration of this treatment modality into the management plan for select patients with MPM, although optimal management is still evolving.
