Quality of life in cancer patients undergoing anticoagulant treatment with LMWH for venous thromboembolism: the QUAVITEC study on behalf of the Groupe Francophone Thrombose et Cancer (GFTC).

ABSTRACT:

Background

Clinical guidelines recommend at least 3-months low molecular weight heparin (LMWH) treatment for established venous thromboembolism (VTE) in cancer patients. However, no study has analyzed the impact of 3-6 months of LMWH therapy on quality-of-life (QoL) in cancer patients.

Results

Among 400 cancer patients included at M0, 88.8% received long-term LMWH. Using a random-effects linear regression model with time as covariate, QoL scores in the MOS SF-36 (Global HRQoL, 1.3-fold per month [95% confidence interval (CI) 0.81-1.79], p < 0.0001) and EORTC QLQ-C30 (global health status/qol, 2.25-fold per month [95% CI 1.63-2.88]; p < 0.0001) questionnaires significantly improved over the 6-month study period in patients treated with LMWH, while VEINES-QOL scores did not change. In the MOS SF-36 and EORTC QLQ-C30, the following factors were associated with change in QoL: symptomatic VTE, cancer dissemination and histological type. Factors pertaining to reduced mobility were also identified as significant predictors of QoL outcomes, including being bedridden in the MOS SF-36 and ECOG score ? 2 in the EORTC QLQ-C30. Presence of acute infection and not undergoing anti-angiogenic therapy were additional factors associated with QoL improvement in the EORTC QLQ-C30.

Methods

QUAVITEC, a prospective, longitudinal, multicenter study, recruited all consecutive eligible adult cancer patients with objectively confirmed VTE between February 2011 and 2012. Patients were asked to answer three QoL questionnaires at anticoagulant treatment initiation (M0) and at 3 (M3) and 6 (M6)-month follow-ups.

Conclusion

QUAVITEC is the first study to show that QoL was improved in cancer patients receiving long-term LMWH treatment for established VTE.

Project description:Essentials Bleeding risk by anticoagulant choice for cancer-associated venous thrombosis (CA-VTE) is unknown. 26 894 people with CA-VTE were followed for bleeding in a claims database in the United States. Hospitalized bleeding risk was similar with direct acting oral anticoagulants vs. warfarin. Relative hospitalized bleeding risk varied by cancer type and anticoagulant choice. SUMMARY: Background Direct acting oral anticoagulants (DOACs) are associated with less bleeding than traditional venous thromboembolism (VTE) treatments in the general population but are little studied in cancer-associated VTE (CA-VTE). Objective To determine whether different anticoagulation strategies for CA-VTE have different hospitalized bleeding rates. Patients/Methods We conducted a retrospective study of patients with CA-VTE, diagnosed between 2011 and 2015, in a large administrative database. Using validated algorithms, we identified 26 894 CA-VTE patients treated with anticoagulants and followed them for hospitalized severe bleeding. Cox models were used to assess bleeding risk, adjusted for age, sex, high dimensional propensity score and frailty. Results Over 27 281 person-years of follow-up (median 0.6 years), 1204 bleeding events occurred, for a bleeding rate of 4.4% per patient-year. Bleeding rates varied by cancer type, with the highest rate for upper gastrointestinal cancers (8.6%) and the lowest for breast cancer (2.9%). In Cox models (hazard ratio [HR]; 95% confidence interval [CI]), compared with warfarin, DOACS and low-molecular-weight heparin (LMWH) had similar hazards of bleeding (HR, 0.88; 95% CI, 0.69-1.11 and 0.98; 0.85-1.13). Compared with LMWH, there was no difference in hazard of bleeding with DOACs (0.86; 0.66-1.12). There was heterogeneity in bleeding risk with DOACs by cancer type, with a higher risk of bleeding in upper gastrointestinal cancers and lower risk of bleeding in prostate cancer and hematologic cancers. Conclusions In this practice-based sample of CA-VTE patients, DOACs were associated with similar bleeding risks to warfarin and LMWH. These findings suggest a complex association of bleeding risk with anticoagulant choice in cancer patients.
