Abstract: Objective

·To explore the feasibility of individualized treatment of malignant pleural effusion (MPE) patients with non-small cell lung cancer (NSCLC) guided by in vitro high-throughput drug sensitivity screening system.

Methods

·Thirty NSCLC patients with MPE treated in Nanjing Chest Hospital from January 2019 to May 2020 were included. The tumor cells in MPE were collected and isolated, and primary cells were cultured. The ex vivo drug sensitivity of primary cells was assessed for 30 chemotherapeutical and molecular targeted drugs by using the high-throughput drug sensitivity screening system of automated digital fluorescence imager. The consistency between the drug sensitivity assay results and the clinical efficacy of patients was evaluated.

Results

·The ex vivo drug sensitivity results of primary tumor cells cultured from MPE revealed considerable heterogeneity in drug response. Most of the primary cells were sensitive to Epirubicin, Lobaplatin, Gemcitabine and Irinotecan. Clinical efficacy of 23 patients can be evaluated. For patients with previously untreated, epidermal growth factor receptor (EGFR) mutation-positive advanced NSCLC, the consistency between the efficacy of targeted therapy and the high-throughput drug sensitivity assay results was 44.4% (4/9). For the EGFR negative untreated patients and EGFR mutation-positive advanced NSCLC patients with acquired resistance to targeted treatment, the consistency between the therapeutic effect of chemotherapy and the high-throughput drug sensitivity assay results was 85.7% (12/14).

Conclusion

·The high-throughput drug sensitivity assay based on MPE primary cell culture in NSCLC patients has a high consistency with the clinical efficacy of chemotherapy, which is helpful for decision-making of personalized chemotherapy.
