No widely accepted method exists to evaluate pediatric hematology oncology patients for the risk of venous thromboembolism (VTE) and the need for prophylaxis. The use of a VTE risk-assessment tool and standardized guidelines for prophylaxis could increase the use of appropriate prophylaxis and reduce the number of VTEs in patients, thereby decreasing morbidity, mortality, hospitalization, and cost. The purpose of this project was to implement and assess the compliance of a pediatric-specific VTE risk-assessment tool in hospitalized pediatric, adolescent, and young adult hematology oncology patients. From the 114 pediatric, adolescent, and young adult patients requiring assessment, 91 (80%) VTE assessments were completed and 87 (96%) were completed accurately. Eighty percent of the at-risk patients were ordered VTE prophylaxis. The use of a VTE risk-assessment tool in pediatric hematology oncology patients is a feasible way to assess patients for their risk of developing a VTE. © 2015 Wolters Kluwer Health, Inc.

HSCT is being increasingly offered as a curative option for children with hematologic malignancies. Although survival has improved, the long-term morbidity ascribed to the HSCT procedure is not known. We compared the risk of chronic health conditions and adverse health among children with cancer treated with HSCT with survivors treated conventionally, as well as with sibling controls. HSCT survivors were drawn from BMTSS (N = 145), whereas conventionally treated survivors (N = 7207) and siblings (N = 4020) were drawn from CCSS. Self-reported chronic conditions were graded with CTCAEv3.0. Fifty-nine percent of HSCT survivors reported ≥ 2 conditions, and 25.5% reported severe/life-threatening conditions. HSCT survivors were more likely than sibling controls to have severe/life-threatening (relative risk [RR] = 8.1, P < .01) and 2 or more (RR = 5.7, P < .01) conditions, as well as functional impairment (RR = 7.7, P < .01) and activity limitation (RR = 6.3, P < .01). More importantly, compared with CCSS survivors, BMTSS survivors demonstrated significantly elevated risks (severe/life-threatening conditions: RR = 3.9, P < .01; multiple conditions: RR = 2.6, P < .01; functional impairment: RR = 3.5, P < .01; activity limitation: RR = 5.8, P < .01). Unrelated donor HSCT recipients were at greatest risk. Childhood HSCT survivors carry a significantly greater burden of morbidity not only compared with noncancer populations but also compared with conventionally treated cancer patients, providing evidence for close monitoring of this high-risk population. © 2011 by The American Society of Hematology.

Background: Many factors influence whether breast cancer patients undergo reconstruction after mastectomy. This study was undertaken to determine the patterns of care and variables associated with the use of reconstruction for ductal carcinoma in situ (DCIS) and to compare previous results for invasive carcinoma. Methods: Postmastectomy reconstruction rates were collected from the California Office of Statewide Health Planning and Development (OSHPD) for 2003-2007. International Classification of Disease-9 codes were used to identify patients undergoing reconstruction after mastectomy. Variations in reconstruction rates were examined by type of breast cancer (DCIS vs. invasive), calendar year, age, type of insurance, type of hospital, and race/ethnicity. Univariate and multivariate odds ratios (OR) with 95% confidence intervals (CI) were estimated for relative odds of immediate reconstruction versus mastectomy only. Results: For multivariate analysis, age, race/ethnicity, type of insurance, and type of hospital were significantly associated with the use of reconstruction for DCIS patients. DCIS patients were twice as likely to undergo reconstruction as patients with invasive cancer (odds ratio (OR) = 1.93, 95% confidence interval (CI) = 1.75-2.13). DCIS patients with private insurance were nine times more likely to undergo reconstruction as patients with Medicaid (OR = 8.84, 95% CI = 5.92-13.21). Both Hispanic white and Asian patients were one-fifth as likely to undergo reconstruction compared with non-Hispanic white patients (OR = 0.18, 95% CI = 0.1-0.3; OR = 0.17, 95% CI = 0.09-0.31). Conclusions: Postmastectomy rates for DCIS were twice those for invasive cancer mostly because stage was not a limiting factor. However, significant factors remain that limit the use of reconstruction in this breast cancer population: age, race/ethnicity, type of hospital, and type of insurance. © Society of Surgical Oncology 2011.
