Combination Chemotherapy the dense core neurosecretory granules associated with SCLC.Active combinations include:cyclophosphamide, doxorubicin, VP-16(CDE), C, doxorubicin, vincristine (CAV),E, cisplatin (EP),VP-16, ifosfamide, P (VIP), andI, carboplatin, VP-16 (ICE).
SCLC cell lines. the dense core neurosecretory granules associated with SCLC.Bone marrow aspirates were obtained from patients and mononuclear cells collected. Lymph node aspirates and other solid tumors were mechanically dissociated and cell suspensions obtained by mincing and passing through 60 gauge steel mesh.The cells were cultured in a serum free medium containing selenium, IGF-I and transferrin. SCLC cells grew as suspension cultures.
SCLC cell lines the dense core neurosecretory granules associated with SCLC.SCLC make their own autocrine growth factors.From 1982-4, NCI established 31 SCLC cell lines. Subcutaneous injection of each of the cell lines into nude mice resulted in tumor formation.The classic SCLC cell lines had high levels of Dopa decarboxylase (DDC:2-657 unit/mg), Bombesin (BB:0.2-22 pmol/mg) and neuron Specific enolase (NSE:1200-18000 ng/mg).Carney et al., Cancer Res. 45:2913 (1985).
SCLC cell lines. the dense core neurosecretory granules associated with SCLC.•Over a 20 year period, NCI established 113 SCLCand 110 NSCLC continuous human cell lines. A subset of SCLC is variant SCLC, which has low levels of DDC, BB and NSE.Phelps et al., J. Cell Bioc. Supp. 24:32(1996).

these patients were still doing well. (Druker et al. N. Engl. J. Med. 2001; 344: 1038.).
. Over a 5 year period, 89% of the patients treated with Gleevec had progression-free survival (O’Hare et al., Clin. Cancer Res. 2011; 17: 212).
●Over a 5 year period, 17% of the patients initially sensitive to Gleevec became resistant.
●BCR-ABL point mutations occurred such as T315I near the ATP binding site impairing Gleevec interactions
●New drugs such as ponatinib or DCC-2036 are being developed which bind with high affinity to mutated BCR-ABL
