               Figure 4. Summary of the IC 50  values for Topotecan and cell lines either as medium controls or supplemented with MAT (Error bars are
               represented by mean values ± SD; all differences are statistically significant)


































               Figure 5. Size distribution of MAT derived from BHGc91 SCLC CTCs. The insert depicts a SEM preparation of BHGc91 MAT (magnification
               2000×, the bar represents 10 µm). CTCs: circulating tumor cells; SCLC: small-cell lung cancer; MAT: material

                                                                                  [10]
               from 4.3 to 5.2 months. This constitutes a significant but minor improvement . In most cases, SCLC has
               excellent response to platinum-based first-line treatment but it invariably recurs as drug-resistant tumor
