No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT03228537). This is a study registration, not published results. Lead sponsor: National Cancer Institute (NCI). Recruitment status: ACTIVE_NOT_RECRUITING. Phase: PHASE1. Study type: INTERVENTIONAL. Enrollment: 28 participants (ACTUAL). Conditions: Biphasic Mesothelioma, Epithelioid Mesothelioma, Stage I Pleural Diffuse Malignant Mesothelioma AJCC v7, Stage IA Pleural Diffuse Malignant Mesothelioma AJCC v7, Stage IB Pleural Diffuse Malignant Mesothelioma AJCC v7, Stage II Pleural Diffuse Malignant Mesothelioma AJCC v7, Stage III Pleural Diffuse Malignant Mesothelioma AJCC v7. Interventions: DRUG: Atezolizumab; DRUG: Cisplatin; PROCEDURE: Extrapleural Pneumonectomy; DRUG: Pemetrexed Disodium; PROCEDURE: Pleurectomy; RADIATION: Radiation Therapy. Primary outcome measures: Feasibility of Neoadjuvant Cisplatin-Pemetrexed-Atezolizumab, Surgery +/- Radiation, and Maintenance Therapy. , Duration of treatment until first dose of maintenance therapy. Includes 21 day cycles of neoadjuvant chemo and surgery - extrapleural pneumonectomy or pleurectomy/decortication (radiation therapy for participants who received extrapleural pneumonectomy).; Safety of Neoadjuvant Cisplatin-Pemetrexed-Atezolizumab, Surgery +/- Radiation, and Maintenance Therapy. , Duration of treatment and follow-up until death or 3 years post Step 1 registration.. Brief summary: This phase I pilot trial studies how well atezolizumab, pemetrexed disodium, cisplatin, and surgery with or without radiation therapy works in treating patients with stage I-III pleural malignant mesothelioma. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving atezolizumab, pemetrexed disodium, and cisplatin before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving atezolizumab after surgery may kill any remaining tumor cells.
