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.

Although the risk for occult lymph node metastasis reached 67.2% in a selected group of patients, elective central neck dissection for patients with PTC increased the risk for complications and did not contribute to a decrease in local recurrence rates.

BackgroundOdontogenic myxoma is a rare benign neoplasm that originates from odontogenic ectomesenchyme. There is no standard of care and recurrences are frequent after conservative surgical procedures.Material and MethodsA retrospective study conducted at a single cancer center, with analysis of medical records of all patients diagnosed with odontogenic myxoma from 1980 to 2010, along with a literature review.ResultsThere were 14 patients with diagnosis of odontogenic myxoma (OM). Most patients were female (78.6%) and Caucasian (100%), with ages ranging from 7 to 51 years (21.6 ± 11.6 years). The time period between the first symptom and first consultation ranged from 0 to 60 months (19.4 ± 19.97 months). The most frequent complaints were increased local volume or failure to tooth eruption. The most common tumor site was the mandible (11 cases, 78.5%). About radiological findings, most lesions were multilocular (9 cases, 64.3%) and with imprecise limits (12 cases, 85.7%). Surgery was performed in all cases and curettage was the most applied technique (10 cases, 71.4%). Three patients underwent mandibulectomy and complex reconstructions including iliac crest microvascular flap. Three patients had postoperative complications and 4 had local recurrences of the tumor. The follow up time ranged from 12 to 216 months (112 ± 70.8 months). All patients are without clinical and radiographic evidence of disease.ConclusionsOM is a locally aggressive and rare tumor. There is no gold standard surgical management and the therapeutic decision should be individualized taking into account the characteristics and extension of the tumor. Key words:Mandible, myxoma, odontogenic, odontogenic tumor.

There has been a significant increase in concern towards improving aesthetic and functional outcomes without compromising the oncologic effectiveness in head and neck surgery. The aim of the current study is to assess the feasibility and oncological outcome of the retroauricular approach for endoscopic and robot-assisted selective neck dissection (SND) for oral cancer in comparison with the conventional SND. A retrospective single institute cohort study was designed. Patients undergoing an SND for oral cavity carcinoma were included and allocated into two groups: (1) retroauricular approach group for endoscopic-assisted or robot-assisted SND or (2) transcervical approach group for the conventional SND. Primary endpoint was the perioperative and postoperative treatment outcomes. Secondary endpoint was the early oncologic outcome. Sixty patients were included (17 retroauricular; 43 conventional). For the primary outcome, only a significant longer operative time in the retroauricular group was identified. No unintentional injury or conversion to the conventional surgery was recorded. There was no significant difference identified in the early oncologic outcome, including number of retrieved lymph nodes and disease-free survival. Postoperative aesthetic results were considered superior when subjectively compared to the conventional approaches. Endoscopic and robot-assisted SND via a retroauricular approach is feasible, safe, and oncologically efficient when compared with the conventional surgery in a short follow-up scenario. It can be used for selected cases with a clear cosmetic benefit. However, further research with longer follow-up and patient satisfaction analysis is mandatory.
