A key determinant of breast cancer outcome in any population is the degree to which cancers are detected at early stages of disease. Populations in which cancers are detected at earlier stages have lower breast cancer mortality rates. The Breast Health Global Initiative (BHGI) held its third Global Summit in Budapest, Hungary in October 2007, bringing together internationally recognized experts to address the implementation of breast healthcare guidelines for early detection, diagnosis, and treatment in low- and middle-income countries (LMCs). ⋯ The effectiveness and efficiency of screening modalities, including screening mammography, clinical breast examination (CBE), and breast self-examination, were reviewed in the context of resource availability and population-based need by the panel. Social and cultural barriers should be considered when early detection programs are being established, and the evaluation of early detection programs should include the use of well developed, methodologically sound process metrics to determine the effectiveness of program implementation. The approach and scope of any screening program will determine the success of any early detection program as measured by cancer stage at diagnosis and will drive the breadth of resource allocation needed for program implementation.

The quality of breast healthcare delivery and the ultimate clinical outcome for patients with breast cancer are directly related to the quality of breast pathology practices within the healthcare system. The Breast Health Global Initiative (BHGI) held its third Global Summit in Budapest, Hungary from October 1 to 4, 2007, bringing together internationally recognized experts to address the implementation of breast healthcare guidelines for the early detection, diagnosis, and treatment in low-income and middle-income countries (LMCs). ⋯ The group agreed that the financial burden of establishing and maintaining breast pathology services is counterbalanced by the cost savings from decreased adverse effects and excessive use of treatment resources that result from incorrect or incomplete pathologic diagnosis. Proper training in breast pathology for pathologists and laboratory technicians is critical and provides the underpinnings of programmatic success for any country at any level of economic wealth.

Inflammation has been implicated in prostate carcinogenesis; therefore, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) has the potential of decreasing the risk of prostate cancer. However, to the authors' knowledge the precise correlation between oral NSAID use, serum prostate-specific antigen (PSA), and prostate cancer risk is unknown. To further characterize this association, the authors evaluated serum PSA levels with regard to NSAID and acetaminophen consumption in a large cross-sectional study of men in the US. ⋯ The findings of the current study suggest that regular NSAID consumption may reduce serum PSA levels. Whether this is indicative of a protective effect on prostate cancer risk or masks possible prostate injury resulting in reduced detection of prostate cancer is unclear. Given the widespread consumption of NSAIDs and the regular use of PSA for the assessment of prostate cancer risk, the potential implications of the current study's findings may be substantial and warrant further investigation.

Salvage stereotactic radiosurgery effectively treats recurrences from whole-brain radiation therapy.
The purpose of the current study was to examine overall survival (OS) and time to local failure (LF) in patients who received salvage stereotactic radiosurgery (SRS) for recurrent brain metastases (BM) after initial management that included whole-brain radiation therapy (WBRT). ⋯ In this study, patients who recurred after WBRT and were treated with salvage SRS were found to have good local control and survival after SRS. WBRT provided good initial control, as 45% of these patients failed >6 months after WBRT. Those with a longer time to failure after WBRT had significantly longer survival after SRS.

Intracranial meningiomas are common, they frequently recur after surgery or radiotherapy, and there are limited data regarding the treatment of intracranial meningiomas with chemotherapy. A phase 2 study was designed to estimate the 6-month progression-free survival of patients with recurrent, treatment-refractory, World Health Organization grade 1 meningiomas who were treated with interferon-alpha. ⋯ Treatment with interferon-alpha for recurrent meningiomas was found to be tolerated moderately well and was modestly effective.
