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.

At Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, a breakdown of technical equipment and lack of pathologists resulted in closure of the surgical pathology laboratory in 2004. At an international meeting in January 2005, 1 USA and 1 Norwegian pathologist were asked if their departments could help with the pathology problem at KATH. This article describes the proposals, the barriers encountered, and the key elements of the final successful collaboration between a low-resource and a high-resource country. ⋯ When needed, paraffin blocks are sent on request. In March 2006, 2 young Ghanaian physicians were received as trainees at the UNN to do full resident work and training with the aim of being approved as specialists in pathology in Ghana by 2010. Full surgical pathology service and training of new pathologists on site are expected to be reestablished at KATH by 2010.

Review Comparative Study
Anticoagulation for the initial treatment of venous thromboembolism in patients with cancer: a systematic review.
The authors compared the relative efficacy and safety of low-molecular-weight heparin (LMWH) and unfractionated heparin (UFH) for the initial treatment of venous thromboembolism (VTE) between patients with and without cancer. ⋯ The current results indicated that LMWH most likely is superior to UFH in reducing mortality in the initial treatment of VTE for patients with cancer. There is a need for more and better designed trials to confirm these findings.

Randomized Controlled Trial
Randomized phase 2 study of subcutaneous amifostine versus epoetin-alpha given 3 times weekly during concurrent chemotherapy and hyperfractionated radiotherapy for limited-disease small cell lung cancer.
The purpose of the current study was to investigate the role of amifostine and epoetin-alpha in reducing severe toxicities during concurrent chemo-hyperfractionated radiotherapy (CCRT) for limited disease small cell lung cancer (LD-SCLC). ⋯ Although amifostine administered 3 times weekly during CCRT did not significantly reduce severe toxicities, epoetin-alpha was effective in preventing severe anemia during CCRT in patients with LD-SCLC. Other radioprotective strategies to minimize severe toxicities should be investigated.

A series of patients with well differentiated (WD)/dedifferentiated (DD) retroperitoneal liposarcoma (RLS) was studied to evaluate the prognostic value of the presence, extension, and grade of the DD component. ⋯ Patients with high-grade DD RLS had a worse prognosis in terms of both DSS and LRFS. The extension of the DD component and its mitotic index were relevant for EFS. The results indicated that radiation therapy may improve LRFS. These data may help stratify the risk of recurrence for patients with RLS. Clinical studies on new multimodality approaches are warranted.
