Which of the following statements about small cell carcinoma of lung is true?: (A) Peripheral in location, (B) Chemosensitive tumor, (C) Bone metastasis is uncommon, (D) Paraneoplastic syndrome with fPTH is common
Answer is B. Small cell lung carcinoma (SCLC) accounts for 20% of primary lung cancers. It is a highly chemosensitive tumor and is primarily treated with chemotherapy and radiation regardless of the stage of presentation. Surgery is indicated for a patient with an incidentally discovered peripheral nodule that is found to be SCLC. Ref: Schwaz's Principles of Surgery, 9th Edition, Chapter 19
