“Our study revealed significant lack of compliance with NCCN guidelines, as well as many disparities in the management of MPM,” Dr. Soukiasian said. “For the overall cohort, 32.3% of patients did not receive any treatment, 18.1% had surgery plus chemotherapy, 38.6% chemotherapy alone, and only 7% received trimodality therapy. In patients with epithelial histology, surgery was significantly underutilized, with only 30% of patients receiving cancer-directed surgery.”
In addition, he said, “our study reveals several disparities that affect compliance with NCCN guidelines. Treatment disparities were observed in women, octogenarians, the uninsured, the Medicaid-insured, and in patients with comorbidities. Guideline adherence was significantly increased in academic and high-volume hospitals with an associated increase in survival.”
But the study also found that median survival estimates were similar regardless of treatment: 10 months for no treatment, 15 months for chemotherapy only, 17 months for surgery only, and 22 months for surgery plus chemotherapy.
During the AATS presentation, an audience member asked about how performance status – a measure of a person’s ability to perform everyday activities – affects the eligibility for surgery.
