SCLC is the most common BP-NET, while LCNEC is rare, %10% and 1%, respectively, of all lung cancers. Both SCLC and LCNEC progress rapidly, are aggressively metastatic, and exhibit a poor prognosis. The incidence of BP-carcinoids (TC and AC) in the US was 1.57 of 100,000 in 2003 (an unexplained and substantial increase over the last 30 years, %6% per year). No curative treatment except for radical surgery (almost never feasible) exists. The slow-growing TC exhibit a fairly good prognosis (%88%, 5-year survival), whereas AC demonstrate a 5-year survival of %50%, and the highly malignant LCNEC and SCLC 5-year survival of 15% to 57% and <5%, respectively. This review provides a broad overview on BPNETs and focuses on the evolution of the disease, general features, and current diagnostic and therapeutic options.
