BACKGROUND Because survival rates among childhood cancer patients are increasing, assessing the risk of second and subsequent malignant neoplasms (SMNs) is ever more important. Using the Childhood Cancer Survivor Study cohort, we identified the risk of SMNS: METHODS A retrospective cohort of 13 581 children diagnosed with common cancers before age 21(More)
Transplant recipients have been reported to have an increased risk of solid cancers but most studies are small and have limited ability to evaluate the interaction of host, disease, and treatment-related factors. In the largest study to date to evaluate risk factors for solid cancers, we studied a multi-institutional cohort of 28 874 allogeneic transplant(More)
As risk for secondary breast cancer is elevated among cancer survivors treated with conventional therapy, we sought to determine the risk among 3337 female 5-year survivors who underwent an allogeneic hematopoietic cell transplantation (HCT) at the Fred Hutchinson Cancer Research Center or at one of 82 centers reporting to the European Bone Marrow(More)
OBJECTIVE To use observational methods to assess the quality of peer relationships in 51 7- to 12-year-old acute lymphoblastic leukemia survivors as compared to healthy children. METHODS Children were audiotaped as they engaged in free play with their best friend and interactions were coded to assess their ability to maintain engagement with one another(More)
PURPOSE To describe survivorship services provided by the Children's Oncology Group (COG), an assessment of services was undertaken. Our overall aims were (1) to describe survivorship services, including the extent of services provided, resources (personnel, philanthropy, and research funding), billing practices, and barriers to care and 2) to describe(More)
BACKGROUND There exist significant challenges to the receipt of comprehensive oncologic treatment for children diagnosed with cancer in sub-Saharan Africa. To better define those challenges, we investigated treatment outcomes and risk factors for treatment abandonment in a cohort of children diagnosed with cancer at the University Teaching Hospital (UTH),(More)
BACKGROUND The incidence of syphilis in Ottawa, Ontario, has risen substantially since 2000 to six cases per 100,000 in 2003, again to nine cases per 100,000 in 2007, and recently rose to 11 cases per 100,000 in 2010. The number of cases reported in the first quarter of 2010 was more than double that in the first quarter of 2009. OBJECTIVE In May 2010,(More)
The recurrence of benign sacral teratomas is a small but significant possibility. Recurrence as an endodermal sinus tumor (EST) with epidural metastases, however, has not been previously reported. The authors describe a case of a mature sacrococcygeal teratoma in a 4-day-old female patient that recurred after 22 months as an EST with epidural metastases.(More)
BACKGROUND There has been little improvement in the survival of adolescent and young adult (AYA) cancer patients aged 15 to 39 years relative to other age groups, raising the question of whether such patients receive appropriate initial treatment. METHODS We examined receipt of initial cancer treatment for a population-based sample of 504 AYAs diagnosed(More)
Qualitative methods can be particularly useful approaches to use with individuals who are experiencing a rare disease and thus who comprise a small sample (such as children with cancer) and are at points in care that few experience (such as end of life). This data-based methods article describes how findings from a qualitative study were used to guide and(More)
