An exception was found in regard to the investigated SCLC patients: Here, the Ki-67-FADIA lead to significantly lower Ki-67 levels in patients with both previous radiotherapy and chemotherapy compared to the untreated SCLC patients (Mann-Whitney-Test: previous chemotherapy vs. untreated group: U = −2.680, p = 0.007; previous radiotherapy vs. untreated group: U = −1.957, p = 0.050) (see Figure S2 – Supplements). Here, MKI67 is linked to small cell lung carcinoma.
