Cervical cancer incidence and mortality rates are significantly higher in low- and middle-income countries compared with the United States and other developed countries. This disparity is caused by decreased access to screening, often coupled with low numbers of trained providers offering cancer prevention and treatment services. However, similar disparities are also found in underserved areas of the United States, such as the Texas-Mexico border, where cervical cancer mortality rates are 30% higher than in the rest of Texas. To address these issues, we have adopted the Project ECHO (Extension for Community Healthcare Outcomes) program, a low-cost telementoring model previously proven to be successful in increasing local capacity, improving patient management skills, and ultimately improving patient outcomes in rural and underserved areas. We use the Project ECHO model to educate local providers in the management of cervical dysplasia in a low-resource region of Texas and have adapted it to inform strategies for the management of advanced cervical and breast cancer in Latin America and sub-Saharan Africa. This innovative approach, using ECHO, is part of a larger strategy to enhance clinical skills and develop collaborative projects between academic centers and partners in low-resource regions.

Cervical cancer is a preventable disease with a known etiology (human papillomavirus), effective preventive vaccines, excellent screening methods, and a treatable pre-invasive phase. Surgery is the primary treatment for pre-invasive and early-stage disease and can safely be performed in many low-resource settings. However, cervical cancer rates remain high in many areas of Latin America. This article presents a number of evidence-based strategies being implemented to improve cervical cancer outcomes in Latin America.

Circulating leptin levels, proinflammatory and T helper cells type 1 (Th1), Th2 cytokine production, and lymphoproliferative response were measured in 15 infants with primary moderate protein calorie malnutrition on admission and after recovery of 10% of weight. Sixteen healthy, well nourished infants of comparable age served as controls. A significant deficit in the z-score of weight for age, weight for height, body mass index, and circulating leptin and growth factors were detected in malnourished infants on admission compared with controls (P < 0.05). These deficits were associated with a significant suppression of the lymphoproliferative response, Th1, and proinflammatory cytokine production (P < 0.05). After a 10% weight gain, a significant increase in circulating leptin levels was produced in parallel with a significant increase in Th1 activity, as revealed by an enhancement in interferon-gamma and a suppression in IL-4 production. Concomitantly, the lymphoproliferative response became similar to that detected in control infants. Furthermore, a significant increase in IL-1 and TNFalpha production compared with that at admission was shown. These findings suggest an association between the increase in leptin and the immunological recovery observed following refeeding of malnourished infants.
