Impact of mild thrombocytopenia on bleeding and recurrent thrombosis in cancer

Haematologica. 2023 Oct 19:0. doi: 10.3324/haematol.2023.284192. Online ahead of print.

ABSTRACT

Thrombocytopenia occurs frequently in patients with cancer-associated thrombosis (CAT), however prospective evaluation of clinical outcomes following randomization to anticoagulants is limited. The HOKUSAI VTE Cancer study was a randomized, open-label, non-inferiority, phase III trial comparing dalteparin with edoxaban in CAT patients. This post hoc analysis of Hokusai VTE Cancer Study was performed to compare outcomes in patients with platelet count ≤100 K/μL at one or more specified time points (baseline, 1-month, or 3-month) versus those without thrombocytopenia. Cumulative incidences at 180 days were calculated with death as a competing risk. The primary outcome was major bleeding; secondary outcomes were clinically relevant non-major bleeding (CRNMB), recurrent thrombosis, and survival. The analysis included 1,045 patients with primarily solid tumor malignancies (89%), median age 65 years, and 52% male. The thrombocytopenia group comprised 9.6% (N=101) of the cohort and relative to the non-thrombocytopenia cohort (N=944), experienced significantly higher major bleeding (9.0% vs. 4.0%, sub-distribution hazard ratio (SHR) 2.4, P=0.02) and CRNMB (17.9% vs. 9.6%, SHR 2.0, P=0.01). Thrombocytopenia did not impact recurrent VTE (9.8% vs. 7.4%, SHR 1.3, P=0.37) nor overall mortality (21.8% vs. 26.0%, HR 0.9, P=0.48). Major bleeding was higher in patients with thrombocytopenia and gastrointestinal malignancies receiving edoxaban versus dalteparin (16.8% vs 0, p.

Incident Cardiovascular Disease Risk Among Older Asian, Native Hawaiian and Pacific Islander Breast Cancer Survivors

Cancer Epidemiol Biomarkers Prev. 2023 Oct 16. doi: 10.1158/1055-9965.EPI-23-0679. Online ahead of print.

ABSTRACT

BACKGROUND: Cardiotoxicity among breast cancer survivors is associated with chemotherapy and radiation therapy. The risk of cardiovascular disease (CVD) among Asian, Native Hawaiian and Pacific Islander (ANHPI) breast cancer survivors in the US is unknown.

METHODS: We used the SEER-Medicare linked database to estimate the risk of CVD among older breast cancer survivors. ICD diagnosis codes were used to identify incident CVD outcomes. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) comparing ANHPI to Non-Hispanic White (NHW) breast cancer patients for CVD, and among ANHPI race and ethnicity groups.

RESULTS: A total of 7,122 ANHPI breast cancer survivors and 21,365 NHW breast cancer survivors were identified. The risks of incident heart failure and ischemic heart disease were lower among ANHPI compared to NHW breast cancer survivors (HRheart failure=0.72, 95%CI=0.61, 0.84; HRheart disease=0.74, 95%CI=0.63, 0.88). Compared to Japanese breast cancer patients, Filipino, Asian Indian and Pakistani, and Native Hawaiian breast cancer survivors had higher risks of heart failure. ischemic heart disease and death. Among ANHPI breast cancer survivors, risk factors for heart failure included older age, higher comorbidity score, distant cancer stage and chemotherapy.

CONCLUSIONS: Our results support heterogeneity in CVD outcomes among breast cancer survivors among ANHPI race and ethnicity groups. Further research is needed to elucidate the disparities experienced among ANHPI cancer survivors.

IMPACT: Filipino, Asian Indian and Pakistani, and Native Hawaiian breast cancer patients had higher risks of heart failure, ischemic heart disease and death among ANHPI breast cancer patients.
