Key Takeaways
- In multimodality pleural mesothelioma, completion of adjuvant chemotherapy (e.g., receiving all planned cycles) is associated with improved survival; cohorts report higher survival in patients who complete therapy
- In EORTC 08031, treatment plan duration was typically 4 cycles (pemetrexed plus cisplatin), linking management intensity to survival
- In PARAMOUNT, maintenance pemetrexed was given for up to 2 years (protocol-specified duration in the trial), affecting longer-term survival exposure
- Median overall survival for peritoneal mesothelioma is commonly reported around 12 months in clinical literature, reflecting typical outcomes
- In a pivotal mesothelioma trial, median overall survival with pemetrexed plus cisplatin was 13 months (control arm), illustrating early benchmark outcomes
- In the MAPS2 trial (multimodality treatment in mesothelioma), median overall survival was 23.0 months, supporting surgery-inclusive survival gains
- In the PROMISE trial context, median overall survival with maintenance nivolumab/other strategies has been reported around 14 months across regimens in published reports, reflecting immunotherapy-era benchmarks
- In KEYNOTE-028 for pembrolizumab in mesothelioma, the objective response rate was 20%, reflecting immunotherapy activity that is often associated with improved survival in responders
- In the CHECKMATE 227 mesothelioma-related immunotherapy investigations, median overall survival is reported to range from ~18–20 months for favorable responders in published interim results, quantifying outcomes in real-world eligible profiles
- The International Association for the Study of Lung Cancer (IASLC) reports that stage at diagnosis is strongly prognostic in pleural mesothelioma, with survival improving for localized disease compared with distant disease
- In a multi-cohort study, histologic subtype (epithelioid vs non-epithelioid) is associated with survival differences, with epithelioid patients having higher median survival than sarcomatoid/biphasic groups
- In the IASLC survival literature, patients with epithelioid histology show better survival than sarcomatoid histology, with hazard ratios favoring epithelioid in multivariable models
- In the same national VA analysis, median overall survival for sarcomatoid/biphasic histology was 6.4 months (reported median OS by histology), quantifying a measurable survival disadvantage
- For malignant pleural mesothelioma treated in U.S. real-world practice, median overall survival was 8.2 months in the AJCC stage-based population analyzed (publication reports time-to-event summary), providing a baseline for survival comparisons
- In that same NCDB analysis, surgery-only median survival was 14.3 months (reported median OS), quantifying the survival benefit remaining without full multimodality exposure
Multimodality treatment with completing planned therapy, plus favorable histology and response, often yields longer mesothelioma survival.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
