VTE remains a common complication of cancer surgery, with a remarkable proportion of events occurring late after surgery. In patients undergoing cancer surgery, VTE is the most common cause of death at 30 days after surgery.

BackgroundCancer patients receiving chemotherapy are at increased risk of thrombosis. Nadroparin has been demonstrated to reduce the incidence of venous and arterial thrombotic events (TEs) by about 50% in cancer outpatients receiving chemotherapy. The aims of this retrospective analysis were to evaluate the thromboembolic risk and the benefit of thromboprophylaxis according to type of chemotherapy.MethodsCancer outpatients were randomly assigned to receive subcutaneous injections of nadroparin or placebo. The incidence of symptomatic TEs was assessed according to the type of chemotherapy. Results were reported as risk ratios with associated 95% CI and two-tailed probability values.Results769 and 381 patients have been evaluated in the nadroparin and placebo group, respectively. In the absence of thromboprophylaxis, the highest rate of TEs was found in patients receiving gemcitabine- (8.1%) or cisplatin-based chemotherapy (7.0%). The combination of gemcitabine and cisplatin or carboplatin increased the risk to 10.2%. Thromboprophylaxis reduced TE risk by 68% in patients receiving gemcitabine; with a further decrease to 78% in those receiving a combination of gemcitabine and platinum.ConclusionsThis retrospective analysis confirms that patients undergoing chemotherapy including gemcitabine, platinum analogues or their combination are at higher risk of TEs. Our results also suggest that outpatients receiving chemotherapy regimens including these agents might achieve an increased benefit from thromboprophylaxis with nadroparin.

Background Standardized salvage treatment has not yet proved eVective in glioblastoma multiforme (GBM) patients who receive prior standard radiotherapy plus concomitant and adjuvant temozolomide. Methods Patients with progressive GBM after radiotherapy plus concomitant and/or adjuvant temozolomide received three-weekly doses (100-75 mg m 2 ) of fotemustine followed, after a 5-week rest, by fotemustine (100 mg m 2 ) every 3 weeks for ·1 year. Results Forty-three patients (29 M, 14 F; median age 51 years, range 34-68; median KPS 90) were enrolled. Progression-free survival at 6 months (PFS-6) was 20.9% (95% CI: 9-33%); three patients (7.1%) had partial response (PR); 15 (34.9%), disease stabilization (SD). The median survival was 6 months (95% CI: 5-7). MGMT promoter status was methylated in 8 (18.6%) and unmethylated in 26 (60.5%) and not assessable in 9 (20.9%) patients, respectively. Disease control was 75% versus 34.6% in methylated and unmethylated MGMT patients (P = 0.044); no signiWcant diVerence was found between groups for PFS-6 and survival. Grade 3 and 4 thrombocytopenia and neutropenia were observed in 20.9 and 16.3% of patients, during the induction phase, and in 0 and 9.5% patients during the maintenance phase, respectively. Conclusions The Wndings of the present trial, that evaluate fotemustine in a homogeneous population, may represent a new benchmark for nitrosourea activity. Moreover, this is the Wrst study to evaluate correlation between MGMT promoter status and outcome of fotemustine for relapsing GBM previously treated with radiotherapy and temozolomide.
