The lesion is most commonly located in the minor (horizontal) fissure of the lung. A pleural pseudotumor is also associated with the presence of dependent pleural effusions. [9]
median overall survival time of approximately 12–16 months, with five-year survival rate of approximately 26% and the long-term survival rate of approximately 4 - 5%. Limited-stage small cell lung carcinoma (LS-SCLC) is a type of small cell lung cancer (SCLC) that is confined to an area which is small enough to be encompassed within a ...
