7080 Background: Circulating tumor cell (CTC) is a surrogate of distant metastasis, and our preliminary study suggested that CTC detected by an EpCAM-based immuno-magnetic separation system (“CellSearch”) was a useful clinical marker in the diagnosis of malignant pleural mesothelioma (MPM) (Tanaka F. et al ASCO 2008). Methods: Patients who presented at our institute to receive pleural biopsy with suspicion of MPM were prospectively enrolled. CTCs in 7.5mL of peripheral blood were quantitatively evaluated with the CellSearch system. Results: Among 136 eligible patients, 104 were finally diagnosed with MPM, and 32 were with non-malignant diseases (NM). CTC was positive (CTC≥1) in 32.7% (37/104) of MPM pts, and in 9.4% (3/32) of NM pts (p=0.011). CTC-count was significantly higher in MPM (range, 0-9) than in NM (range, 0-1; p=0.007). According to a ROC curve analysis, the CTC-test provided a significant diagnostic performance in discrimination between MPM and NM (AUC= 0.623; P=0.036). Among MPM pts, CTC-positivity and CTC-count were significantly increased with tumor progression (p=0.026 and p=0.008, respectively). For all MPM pts, there was no significant difference in overall survival between CTC-positive and negative pts. However, in a planned subset analysis, CTC was a significant factor to predict poor prognosis (median survival time, 8.0 months for CTC-positive pts, and 20.3 months for negative pts; p=0.012) in pts with epithelioid-type MPM in which CTC was exclusively positive; a multivariate analysis confirmed that CTC, along with PS, was an independent prognostic factor (HR=2.38; P=0.006). Conclusions: CTC was a significant diagnostic marker in discrimination between MPM and NM. CTC-positivity was a significant and independent prognostic factor to predict a poor prognosis of epithelioid MPM. [Table: see text]

Background: The prognostic value of programmed death-ligand 1 (PD-L1) expression in patients with malignant pleural mesothelioma (MPM) has been controversial according to previous investigations. Therefore, we conducted a meta-analysis to assess the potential prognostic significance of PD-L1 expression in MPM. Methods: PubMed, Embase, Web of Science, Scopus, and the Cochrane Library were thoroughly searched for relevant original articles published before 9 April 2020. The pooled hazard ratios (HRs) and 95% confidence intervals (CIs) of overall survival (OS) and progression-free survival (PFS) were calculated. The results of the meta-analysis were verified using The Cancer Genome Atlas (TCGA) dataset. Results: In total 16 studies were included in our meta-analysis. A high PD-L1 expression was associated with a poor OS (HR = 1.53, 95% CI = 1.28–1.83, p < 0.001), but not a grave PFS (HR = 1.07, 95% CI = 0.82–1.39, p = 0.643) in MPM. Furthermore, the PD-L1 expression correlated with the sarcomatoid + biphasic type of MPM (odds ratio = 4.32, 95% CI = 2.16–8.64, p < 0.001). TCGA data indicated that PD-L1 was a significant prognostic factor for OS (HR = 2.069, 95% CI = 1.136–3.769, p = 0.0175), but not for PFS (HR = 1.205, 95% CI = 0.572–2.539, p = 0.624), which was in accordance with the results of the meta-analysis. Conclusion: A high PD-L1 expression is a significant prognostic factor for poor OS of patients with MPM. We therefore suggest that PD-L1 expression levels can be used to predict the clinical outcomes of patients with MPM in the future.

e18545 Background: Maintenance chemotherapy with pemetrexed is not the standard treatment of choice in patients with locally advanced or metastatic epiteliomorfe malignant pleural mesothelioma (EMPM). We would assess the safety and efficacy of a treatment with pemetrexed until progression disease after 4 or 6 cycles of induction therapy with or without platin. Methods: From July 2008 to September 2012, 21 patients (18 males and 3 females with a median age of 67 years range 58-84) with locally advanced or metastatic epiteliomorfe malignant pleural mesothelioma (EMPM) were enrolled. In all patients histology was epiteliomorfe malignant mesothelioma. Only 15 patients (71,4%) had a PS 0 whereas 6 (28,6%) had a PS 1. All patients received an induction therapy with or without platin. Each patient received an average of 5,6 cycles of induction chemotherapy. Then all patients received a maintenance chemotherapy with pemetrexed 500 mg/mq intavenously over 10 minutes every 3 weeks. Each patient received an average of 7,3 cycles of maintenance chemotherapy. All patients received folic acid and vitamin B12 supplementation to improve safety. Results: At the time of analysis all patients were evaluable for response. Fourteen patients (66,6 %) had a partial response and two of these underwent surgery and obtained a complete response. Six patients (28,5%) had a stable disease. The median overall survival was 13 months, while median progression-free survival was 11 months. Grade 2-3 of WHO haematological toxicities (anemia and neutropenia) occurred in 4 patient (19%). We also observed grade 2-3 of WHO gastrointestinal toxicities (diarrhea, nausea and vomiting) in 2 patient (9.5%). Grade 2 of lack of appetite and asthenia occurred in 3 patients (14.3%). Conclusions: Our data show that a maintenance chemotherapy with pemetrexed in EMPM resulted in a moderate overall survival (13 months). These results indicate that patients with EMPM could benefit from a maintenance treatment with pemetrexed.
