Abstract

In our previous study, a microfluidic system was developed based on podoplanin detection for capturing circulating tumor cells (CTCs), derived from malignant pleural mesothelioma (MPM). However, non‑epithelioid MPM shows low podoplanin protein expression compared with that in epithelioid MPM; thus, some CTC populations may be missed. To overcome this limitation, a new CTC‑detection chip was developed by combining the conventional podoplanin antibody (clone: NZ‑1.2) with an epidermal growth factor receptor (EGFR)‑targeted antibody (cetuximab). The cell‑capture efficiency of the Cocktail‑chip reached 100% in all the histological MPM cell lines. The median CTC‑counts from 19 patients with MPM (epithelioid/non‑epithelioid: 10/9) with the NZ‑1.2‑ and Cocktail‑chips were 1 and 3 (P=0.311) in 1 ml peripheral blood, 1.5 and 2 (P=0.332) in epithelioid MPM, and 1 and 3 (P=0.106) in non‑epithelioid MPM, respectively. Overall, the Cocktail‑chip showed an improved ability to detect more CTCs in patients with non‑epithelioid MPM compared with that in the conventional NZ‑1.2‑chip, showing non‑significant, but higher CTC detection. Furthermore, CTC‑counts, determined using the Cocktail‑chip were significantly correlated with the clinical stage of non‑epithelioid MPM. In epithelioid MPM, the Cocktail‑chip achieved a CTC‑detection efficiency equivalent to that in the conventional NZ‑1.2‑chip. The Cocktail‑chip enabled sensitive CTC detection of all histological MPM, including the non‑epithelioid subtype, which may provide a foundation for the diagnosis, treatment, and prognosis of MPM progression.
