Many western countries have established female human papillomavirus (HPV) vaccination programs for the prevention of cervical cancer. The quadrivalent HPV vaccine (HPV4) has proven efficacy against additional HPV-related disease in both sexes, but the cost effectiveness of male HPV vaccination remains controversial. To assess the cost effectiveness of male HPV vaccination in Canada with respect to oropharyngeal cancer (OPC), the authors performed a preliminary cost-effectiveness analysis. ⋯ On the basis of this model, HPV vaccination for boys aged 12 years may be a cost-effective strategy for the prevention of OPC in Canada.

The authors investigated whether residential segregation (the degree to which racial/ethnic groups live separately from one another in a geographic area) 1) was associated with mortality among urban women with breast cancer, 2) explained racial/ethnic disparities in mortality, and 3) whether its association with mortality varied by race/ethnicity. ⋯ Among urban women with breast cancer in Texas, segregation has an independent, adverse association with mortality, and the effect of segregation varies by patient race/ethnicity. The novel application of a small-area measure of relative racial segregation should be examined in other cancer types with documented racial/ethnic disparities across varied geographic areas.

Multicenter Study
Unrelated cord blood compared with haploidentical grafts in patients with hematological malignancies.
Alternative donors, such as unrelated umbilical cord blood (UCB) and related haploidentical (haplo) donors, are more and more frequently searched for and used for patients who are candidates for allogeneic hematopoietic stem cell transplantation but are without a suitable related or unrelated donor. The aim of the current retrospective study was to compare the outcome of patients after haplo and UCB grafts prepared using a nonmyeloablative conditioning regimen. ⋯ The results of the current study suggest that for patients with high-risk hematological diseases without a related or unrelated donor, haploidentical transplants are a promising alternative option that deserves further investigation.

Many patients with incurable cancer inaccurately believe that chemotherapy may cure them. Little is known about how such beliefs affect choices for care at the end of life. This study assessed whether patients with advanced cancer who believed that chemotherapy might offer a cure were more likely to receive chemotherapy in the last month of life and less likely to enroll in hospice care before death. ⋯ An understanding of the purpose of chemotherapy for incurable cancer is a critical aspect of informed consent. Still, advanced cancer patients who were well informed about chemotherapy's goals received late-life chemotherapy at rates similar to those for other patients. An understanding of the incurable nature of cancer, however, is associated with increased hospice enrollment before death, and this suggests important care outcomes beyond chemotherapy use.

Comparative Study
Comparison of oncology drug approval between Health Canada and the US Food and Drug Administration.
The drug approval timeline is a lengthy process that often varies between countries. The objective of this study was to delineate the Canadian drug approval timeline for oncology drugs and to compare the time to drug approval between Health Canada (HC) and the US Food and Drug Administration (FDA). ⋯ The time from HC submission to HC approval takes 3 months longer than the same time interval for the FDA. To the authors' knowledge, this is the first documentation of the time required to bring an oncology drug from HC submission to placement on a provincial drug formulary.
