Which of the following statements about small cell carcinoma of lung is true?

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
