Abstract

Background

BM occur frequently within 1 year after CRT for stage III NSCLC. It is unknown whether the specific chemotherapy used influences subsequent BM development.

Methods

Retrospective multicenter study including all consecutive stage III NSCLC patients (pts) who completed CRT. Primary endpoints: BM development within the 1st year and whether this was the only site of first relapse. Differences between regimens were assessed with a logistic regression model including known BM risk factors (age, gender, histology, T- and N-status) and the specific chemotherapy used (concurrent (cCRT) vs sequential (sCRT), within cCRT: low dose cisplatin monotherapy (LDC) – high dose polychemotherapy; (non-)taxane high dose polychemotherapy – LDC; chemotherapy subgroups of ≥50 pts).

Results

Between January 2006 and June 2014, 838 pts were eligible (737 cCRT, 101 sCRT). 11% developed BM within a year, 5% had BM as only site of first relapse. BM pts were significantly younger (mean age 59 vs 63 years, p 

Conclusions

Approximately 1 out of 10 pts will develop BM within the 1st year after stage III NSCLC diagnosis, but this does not depend on the type of chemotherapy regimen used within a CRT regimen.
