Radiation therapy plays a critical role in the management of breast cancer and often is unavailable to patients in low- and middle-income countries (LMCs). There is a need to provide appropriate equipment and to improve the techniques of administration, quality assurance, and use of resources for radiation therapy in LMCs. Although the linear accelerator is the preferred equipment, telecobalt machines may be considered as an acceptable alternative in LMCs. Applying safe and effective treatment also requires well trained staff, support systems, geographic accessibility, and the initiation and completion of treatment without undue delay. In early-stage breast cancer, standard treatment includes the irradiation of the entire breast with an additional boost to the tumor site and should be delivered after treatment planning with at least 2-dimensional imaging. Although postmastectomy radiation therapy (PMRT) has demonstrated local control and overall survival advantages in all patients with axillary lymph node metastases, preference in limited resource settings could be reserved for patients who have >/=4 positive lymph nodes. The long-term risks of cardiac morbidity and mortality require special attention to the volume of heart and lungs exposed. Alternative treatment schedules like hypofractionated radiation and partial breast irradiation currently are investigational. Radiation therapy is an integral component for patients with locally advanced breast cancer after initial systemic treatment and surgery. For patients with distant metastases, radiation is an effective tool for palliation, especially for bone, brain, and soft tissue metastases. The implementation of quality-assurance programs applied to equipment, the planning process, and radiation treatment delivery must be instituted in all radiation therapy centers.

The management of locally advanced breast cancer (LABC) is guided by scientific advances but is limited by local resources and expertise. LABC remains very common in low-resource countries. The Systemic Therapy Focus Group met as part of the Breast Health Global Initiative (BHGI) Summit in Budapest, Hungary, in October 2007 to discuss management and implementation of primary systemic therapy (PST) for LABC. PST is standard treatment for large operable breast cancer in enhanced-resource settings and, in all resource settings, should be standard treatment for inoperable breast cancer and for LABC. Standard PST includes anthracycline-based chemotherapy. The addition of sequential taxanes after anthracycline improves pathologic responses and breast-conservation rates and is appropriate at enhanced-resource levels; however, costs and lack of clear survival benefit do not justify their use at limited-resource levels. It remains to define better the role of endocrine therapy as PST, but it is acceptable in elderly women. Aromatase inhibitors have produced better results than tamoxifen in postmenopausal patients and are used in enhanced-resource settings. The less expensive tamoxifen remains useful in low-resource countries. Trastuzumab combined with chemotherapy yields high pathologic response rates in patients with HER2/neu-overexpressing tumors; its use in low-resource countries is limited by high costs. Most studies on PST of LABC were conducted in countries with enhanced resources. BHGI encourages conducting clinical trials in countries with limited resources. Cancer 2008;113(8 suppl):2315-24.
