Patient case: 55-year-old male with Melanoma. Genetic variant: NRAS (Q61K). Other conditions: Hypertension.

Clinical trial: Feasibility Study of CDDP + CPT-11 + PSK for Extensive-Stage Disease (ED) Small Cell Lung Cancer

Summary: The purpose of this study is to examine whether setting test groups of cisplatin + irinotecan + Krestin therapy as first-line treatment and chemotherapy (radiotherapy or radiotherapy + chemotherapy also allowed) combined with Krestin as second-line treatment after exacerbation and comparing with historical control or community control is appropriate as the protocol and regimen for the phase III clinical trial on extensive-stage disease (ED) small cell lung cancer.

Detailed description: To examine whether the following protocol and regimen is appropriate for the phase III clinical trial on extensive-stage disease (ED) small cell lung cancer: set test groups of cisplatin + irinotecan + Krestin therapy as first-line treatment and chemotherapy (radiotherapy or radiotherapy + chemotherapy also allowed) combined with Krestin as second-line treatment after exacerbation, evaluate the efficacy and safety of treatment in a small number of cases, and compare with historical control or community control.
