RBMS3, NEDD9, CRIM1, KPNA2, GPR137C, GRIK3, hsa-miR-7–5p, hsa-miR-18a-5p, hsa-miR-144–3p, hsa-miR-1–3p along with the pathways included protein kinase B signaling, muscle structure development, Cell Cycle (Mitotic) and blood vessel development may gain a high chance to play a key role in the prognosis of SCLC, but more studies should be conducted to reveal it more clearly. The gene discussed is KPNA2; the disease is small cell lung carcinoma.
