Introduction/Background Cervical cancer is the most prevalent in Brazil North Region. There are few studies about cervical injuries in the riverine women. The knowledge of these characteristics could improve health assistance to these women, contributing to health policies that benefit this population. Objective: This paper aims to evaluate the cervical oncological cytologies of the riverine women from rivers Tapajós and Cupari (Pará - Brazil).

Methodology A partnership between SLMandic Medical School and the local Cities of Santarém, Aveiro and Belterra (State of Pará, Brazil) Government was established trhough ‘Barco da Saúde’ (Health Boat) project. The Counties have provided a Hospital Boat named ‘Abaré’. SLMandic has provided a team made up by professors and medical students. Services in pediatrics, gynecology and obstetrics, dermatology, ophthalmology and odontology were provided. In 2019, the activities were held between July 27nd and August 5th, 206 gynecological and obstetric appointments were made and 133 cervical oncological cytologies were collected. Epidemiological data were collected from anamnesis form designed specifically for the expedition. The reading of the cytology slides was performed and de injuries classified among high grade lesions (HSIL), low grade lesions (LSIL), scaly lesions of undetermined significance (ASC-US), and glandular lesions of undetermined significance (ASCH). Pathological agents found have also been described. The samples were classified between satisfactory and unsatisfactory. Finally, statistical analysis of data was done.

Results Out of 206 gynecological and obstetric appointments, 132 (64.1%) cervical cytologies were collected. Among these patients, 100 (75.75%) were screening age (25–65 years old). Median of patients age was 34.4 years old. About 128 (97%) samples were satisfactory for analysis. Cervical cancer screening was the objective of the exam in 101 (76.5%) of the cases. Related to associated microorganisms, Lactobacillus sp. were present in 68 (51.5%), Gardnerella vaginallis in 13 (9.8%), Candida sp. in 8 (6%) Trichomonas vaginallis in 2 (1,5%), in addition to others less prevalent. Inflammatory cells were present in 126 (95.5%) of the cases. The main diagnosis was benign cellular changes (122 – 92.5%) and atypical squamous cells of undetermined significance, ASC-US, 6 (4.5%). Were performed 7 (5.3%) biopsies, being 3 (42.9%) cervical polyps and 4 (57.1%) nonspecific chronic cervicitis.

Conclusion Despite difficulties to access health care, health indicators were better than expected. There was good cytological coverage and no high-grade lesions were found.
