Use of interventional bronchoscopic treatment in small cell lung cancer

Small cell lung cancer (SCLC) constitutes 15%-25% of all lung cancers. Their treatment approach is different from nonsmall cell lung cancer. Central airway obstruction develops at the time of diagnosis or eventually at some time as the disease progress. Quick relief of symptoms with chemotherapy will cause to postpone interventional bronchoscopy which divest patient from benefits of this procedure. There is a few data about the use of interventional bronchoscopy in SCLC.

Between January 2005 and December 2012, rigid bronchoscopy under general anaesthesia was done in a total of 944 cases. Among them, 52 consecutive SCLC cases were evaluated retrospectively.

Survival was calculated from the date of application of therapeutic bronchoscopy using statistical software.

From the 52 cases (41 males) mean age of the patients were 56,87 ± 10,16 (range 34-78). Most common obstruction areas were distal trachea and carina invasion involving both main bronchus (n: 12; 23%). Most common method used was mechanical desobstruction after coagulation with diode diode laser or APC. A total of 16 stents was applied to 15 of the cases from 52 cases (28.8%). Most common used stent was silicon Y stent (n: 11). Most common complication during the procedure was bleeding that was mild in 11 cases and massive in 1. One patient died during the procedure (1.9%).

Multimodal interventional bronchoscopic methods seem to be a last option but may be useful in the management of advanced airway obstruction in the setting of SCLC. The choice of modality may be chosen depending upon individual patient characteristics as appropriate.
