SCLC, factoids 15 – 25 % of all lung cancers Almost exclusively in smokers Distinguished from NSCLC by: Rapid doubling time High growth fraction Early development of wide-spread mets
Slide 29-

SCLC, factoids (cont’d) Considered highly responsive to “chems and beams” BUT…usually relapses within 2 years despite treatment Overall, only 3 –8 % of all patients survive more than 5 years Most common malignancy associated with Neurologic paraneoplastic syndromes
Slide 30-

SCLC, pathology Most recent (1999) WHO classification Classical small cell carcinoma Large cell neuroendocrine cancer Combined small cell carcinoma with some NSCLC Cells are approx. 2 X’s the size of normal lymphocytes

SCLC, pathology
Slide 33-

SCLC, clinical presentation Typically arise centrally Most common presentation is a large hilar mass with bulky mediastinal LAN Common symptoms cough, SOB, wt loss Approx. 70 % with overt mets at presentation Commonly spread to liver, adrenals, bone and brain Can present with paraneoplastic syndome
Slide 34-

SCLC, tumor markers 3 main groups: Neural, Epithelial, Neuroendocrine Epithelial: virtually all SCLCs are immunoreactive for Keratin and Epithelial Membrane Antigen 1 or more markers of Neural/Neuroendocrine differentiation found in approx. 75 % of SCLCs
Slide 35-

SCLC, tumor markers Leads to expression of dopa decarboxylase, calcitonin, neuron-specific enolase, chromogranin A, CD-56 (a neural cell adhesion molecule) gastrin releasing peptide and insulin-like growth hormone Occasionally patients produce antibodies that cross-react with both the SCLC cells and the CNS  cerebellar degeneration syndromes SCLC cells can produce a number of polypeptide hormones including ACTH and Vasopressin
Slide 36-

Neurologic Paraneoplastic Syndromes
Slide 37-

Lung cancer, Paraneoplastic Syndromes
Slide 38-

SCLC, genetics Development of lung cancers occur through stimulation of proliferation and mutagenesis, occurring over YEARS and resulting from exposure to tobacco and other carcinogens
Slide 39-

SCLC, genetics The most common genetics of SCLC are: P53 mutation is present in 75 -90 % Loss of heterozygosity of c-somes 9p and 10q in the majority Deletion of 3p  inactivation of as many as 3 tumor suppressor genes Loss of the retinoblastoma gene function is nearly ubiquitous Activation of telomerase in approx. 90 % (allows cells to divide forever)
