Clinical research progress of first-line immunotherapy for extensive-stage small cell lung cancer

Small cell lung cancer(SCLC)has a high degree of malignancy and rapid progression,and most of the patients are in the extensive stage when they are diagnosed.The traditional treatment of SCLC is mainly systematic chemotherapy combined with radiotherapy,but there has been no significant progress for many years.The emergence of immunotherapy represented by immune checkpoint inhibitors(ICIs)has changed the treatment pattern of SCLC.Some studies have confirmed the effect of ICIs monotherapy.However,the disadvantages of ICIs monotherapy such as low responsiveness,drug resistance,and adverse reactions limited the clinical application.The combined treatment of immune checkpoint inhibitors was newly developing treatment models.Clinical studies have found that ICIs combined with standard chemotherapy can significantly improve the survival of patients with extensive small cell lung cancer without increasing adverse reactions.Based on the synergistic effect of immunotherapy combined with chemotherapy,this paper reviews the current progress,deficiency and future exploration direction of first-line immunotherapy for extensive small cell lung cancer.

Explain the relationship between the theory of spleen viscera and the pathogenesis of malignant tumors from the perspective of system theory

The spleen visceral manifestation theory(SVMT)is formed under the simple holistic thinking mode of traditional Chinese medicine(TCM).It emphasizes the change of our organic function.And SVMT can make me to understand the basic characteristics and rules of the organic functional change and disease evolution of spleen(which is a complex giant system from a macroscopic view).However,the formation of SVMT is still in the stage of fuzzy deduction,ignoring the structural basis of its function.As a result,although SVMT has a macroscopic accuracy,it is unable to analyze the internal structure from the perspective of reductionism.The systematic thought of unifying reductionism and holistic dialectics provides the possibility for the relationship between traditional Chinese medicine(TCM)theory and modern scientific research.Based on the systematic relationship between spleen storage and malignant tumor,this paper tries to take matter-energy-information as the starting point by drawing lessons from complex scientific theory and using the method of interdisciplinary comprehensive analysis under the guidance of system theory.Explore its mechanism and law more scientifically from the subcellular level,so as to further improve and deepen the theoretical system of malignant tumor research based on SVMT.
