Objectives
Thromboembolic events (TE) are common in patients with cancer and are potentially life-threatening. In lung cancer, little is known about thrombosis during chemotherapy treatment. The aim of this study was to describe the incidence of TE in patients with non-small cell lung cancer (NSCLC), occurring during treatment with platinum-based chemotherapy.
Methods
We retrospectively selected patients with NSCLC treated with platinum-based chemotherapy at the VU University Medical Center Amsterdam between 2000 and 2012. Patients who underwent recent surgery were excluded. All TE were included that occurred from start of chemotherapy treatment until 30 days after last administration.
Results
Among 784 included patients, 63 (8.0%) patients had 69 TE during treatment. Forty-five venous TE (VTE) and 24 arterial TE (ATE). Six patients had multiple events within treatment period, 3 of which had simultaneous ATE and VTE. In total, 613 patients were treated with cisplatin, 119 patients received carboplatin and 52 patients received both in first- or second-line treatment. In 8% (55/665) of the patients exposed to cisplatin a TE had occurred vs. 5% (8/171) in patients exposed to carboplatin (p=0.42). The majority of TE occurred in the first 2 cycles (70%). History of TE was related to occurrence of TE during chemotherapy (p<0.01). Median PFS was similar in patients with and without TE (6.2 vs. 7.2 months, respectively; p=0.10). Median OS was significantly shorter in patients with TE (9.5 vs. 12.9 months, respectively; p=0.03).
Conclusion
In our series, both ATE and VTE were a common finding during chemotherapy. TE was a poor prognostic factor. No difference in TE incidence was found between patients treated with cisplatin or carboplatin.
