Eligible studies included prospective randomized phase II and III trials evaluating cisplatin-based versus non–cisplatinbased chemotherapy in patients with solid tumors. • Data on all-grade VTEs were extracted. • Incidence rates, relative risks (RRs), and 95% CIs were calculated using a random effects model. Results • A total of 8,216 patients with various advanced solid tumors from 38 randomized controlled trials were included. The incidence of VTEs was 1.92% (95% CI, 1.07 to 2.76) in patients treated with cisplatin-based chemotherapy and 0.79% (95% CI, 0.45 to 1.13) in patients treated with non–cisplatin-based regimens. • Patients receiving cisplatin-based chemotherapy had a significantly increased risk of VTEs (RR, 1.67; 95% CI, 1.25 to 2.23; P .01). • Exploratory subgroup analysis revealed the highest RR of VTEs in patients receiving a weekly equivalent cisplatin dose 30 mg/m2 (2.71; 95% CI, 1.17 to 6.30; P .02) and in trials reported during 2000 to 2010 (1.72; 95% CI, 1.27 to 2.34; P .01). Conclusion • Cisplatin is associated with a significant increase in the risk of VTEs in patients with advanced solid tumors when compared with non–cisplatin-based chemotherapy.

J Clin Oncol 2000, 18: 2169-78 VTE in cancer patients: the role of hormone therapy and chemo- endocrine therapy Authors observed one or more thromboembolic events in 48 of 353 women (13.6%) randomized to receive tamoxifen plus CMF compared to 5 of 352 women (2.6%) randomized to receive tamoxifen alone (p=0.001). Significantly more women developed severe VTE in the T plus CMF arm than in the T arm (34 vs 5: p=0.0001). Most thromboembolic events occurred while women were actually receiving chemotherapy ( 39 of 54, p<0.0001). Pritchard K. Et al.

New agents in medical oncology and the risk of venous thromboembolism Lenalidomide and Thalidomide Ten patients (8%) developed deep vein thrombosis, including 4 who were not receiving any thromboprophylaxis at the time of the event. The rate of thromboembolic events was not different between patients who received concomitant erythropoietin therapy and those who did not, 4.8% and 8.6%, respectively (P = .54). A higher number of venous thrombotic episodes occurred in the high-dose corticosteroid group compared with the lowdose corticosteroid therapy group (12% vs 6%), but the difference was not statistically significant (P = .3).

Early thromboembolic events are essentially related to the loss of vessel integrity caused by CVC placement. Late thromboembolic events are probably related to CVC features, insertion technique, catheter tip position, and occurrence of catheter infection. The role of thrombophilic molecular abnormalities is less clear. Venous thrombosis in cancer patients CVC-related DVT in cancer patients complicates the management of the disease contributing to the morbidity and mortality of cancer patients. Recognition of risk factors associated with CVC-related DVT may help to reduce the rate of this complication. This objective is more likely to be achieved by pharmacologic prophylaxis during long-term CVC dwell.
