    Objective: To describe and analyze the prevention of uterine cervix cancer in the Indigenous Park of Xingu, Mato Grosso, within the period from 2005 through 2006. Methods: This is an observational, transverse, retrospective study, performed by means of collection of data concerning the actions toward the prevention of uterine cervix cancer within the Xingu Project, of the Federal University of São Paulo (UNIFESP). The population universe comprised 503 indigenous women, with age equal to or higher than 12 years and a sexual life history, belonging to seven ethnic groups, living within the Medium, Low and Eastern Xingu regions. The data collection and analysis were developed as of three actions: tracing of uterine cervix cancer, made along the months from October through December, 2005, colposcopy in February 2006 and radiofrequency waves surgery (CORAF), classic conization and hysterectomy in May, 2006. Results: The comprehensiveness of the cytopathologic exam in the year 2005 was of 99.6%. The age of patients varied from 12 to 75 years, with median of 25 years, with predominance (61.4%) of young women within the age range of 12 to 29 years. 59 cases (11.7%) were identified with cytologic atypias so distributed: 3.0% of atypical squamous cells with undefined significance (ASC-US), 2.3% of atypical squamous cells without disregarding high-grade lesion (ASC-H), 1.4% atypical glandular cells (AGC), 3.0% of low-grade squamous intraepithelial lesion (LBG), 1.6% high-grade squamous intraepithelial lesion (LAG), 0.2% de spinocellular carcinoma (CEC) and 0.2% adenocarcinoma (ACA). A predominance of acetowhite epithelium (81.4%) was noticed in the 58 colposcopic exams. 13 cases (30.2%) of LAG, 11 cases (25.6%) of LBG and 19 cases (44.2%) of chronical cervicitis were noticed in the 343 anatomopathologic exams of colposcopically-driven biopsies. A predominance of LAG (92.3%) was noticed within the age range of 20 to 49 years, LBG (36.4%) from 12 to 19 years and beyond 60 years. The excision of the transformation zone by CORAF was indicated in 20 cases (44.2%). The classical conization and hysterectomy were indicated in 2 cases (4.6%), from 12 to 19 years and. The cytopathologic exam indicated a 54% sensibility and 97% specificity, positive predictive value of 88% and negative predictive value of 83%. The cytopathologic exam indicated 54% sensibility, 97% specificity, positive predictive value of 88% and negative predictive value of 83%. The sensibility of the anatomopathologic exam of the biopsy was of 72.2%, specificity of 100%, positive predictive value of 100% and negative predictive value of 44.4. Conclusions: The results from the organized uterine cervix cancer program in Xingu were: a broader comprehensiveness and quality in cytopathologic exams, early detection of cervical intraepithelial lesions, guarantee of treatment and 100% follow-up of detected cases, a higher resolution, a significant reduction of uterine cervix cancer events and their preceding lesions. The participation of UNIFESP professionals, with matricial support was fundamental for the success of this work.
