Lesbian, gay, and bisexual populations are not part of cancer surveillance, resulting in scarce information about the cancer survivorship of these populations. To address this information gap, the authors examined the prevalence of cancer survivorship by sexual orientation and cancer survivors' self-reported health by sexual orientation. ⋯ Our novel findings suggest sex differences in the impact of cancer on lesbian, gay, and bisexual cancer survivors. Lesbian and bisexual cancer survivors need to be targeted by programs and services to assist these cancer survivors in improving their health perceptions, whereas healthcare providers and public health agencies need to be made aware of the higher prevalence of cancer in gay men to prevent future cancers through increased screening and primary prevention.

Dapsone, used for Pneumocystis jiroveci (PCP) prophylaxis, is associated with increased risk of methemoglobinemia. Absence of cytochrome b5 reductase enzyme activity causes congenital methemoglobinemia, but its role in dapsone-associated methemoglobinemia is unknown. The authors sought to elucidate drug-related risk factors for dapsone-associated methemoglobinemia in pediatric oncology patients, including contribution of cytochrome b5 reductase enzyme activity. ⋯ Methemoglobinemia occurred in almost 20% of pediatric oncology patients receiving dapsone for PCP prophylaxis. Higher dapsone dosing is associated with increased risk. A cross-sectionally acquired cytochrome b5 reductase enzyme activity level was not associated with methemoglobinemia risk. Studies are needed to define biologic correlates of methemoglobinemia and evaluate lower dapsone doses for PCP prophylaxis.

Patient navigation represents an opportunity to further the integration of palliative care with standard cancer care. This article defines palliative and hospice care and describes some of the current challenges of integrating palliative care into other forms of care. ⋯ Although these outcomes may not have been specifically assessed in patients in cancer navigation programs, they represent important outcomes for patients receiving palliative care and their families. It is recognized that the types of outcomes that are important to track for patients and families receiving palliative care should be consistent with outcomes at other stages of illness.
