About

Main objectives: 1.1. To evaluate the use of self-sampling for HPV test in regular attendants of cervical cancer screening as a primary sample collection method. 1.2. To assess the impact on the acceptability of an educational intervention. 1.3 Confirm the concordance of HPV detection in the samples collected by the professional and in self-sampling. Project methodology: Randomized, parallel multicenter clinical trial in women aged 30-65 years regularly attending cervical cancer screening residents in the Autonomous Communities of Catalonia and the Canary Islands (Spain). The woman attends the routine screening visit where the health professional collects a sample from the cervical screening. She then offers her the study and if the woman accepts, she offers her the SS as a screening test. The modality of information and practice of the self-sampling is random: 1. Training group): Educational intervention with self-sampling practice: clinician-led explanation on how to proceed with self-sampling prior to collecting a self-sample at the clinic. 2. No prior trainning group): Same training without practicing self-sampling collection. Both groups has a standard of care cervical sample collection by a clinician. Women are asked to return a self-sampling specimen one month after the baseline visit together with an acceptability questionnaire on self-sampling use. Acceptability will be analyzed according to two definitions: * proportion of women who returned the self-sampling device, * proportion of women who report wanting to use self-sampling in future screens in the acceptability questionnaire. HPV agreement between collection methods will be calculated using Cohen's Kappa coefficient. Cost-effectiveness analisis will be done on public health system by a mathematical model of the cervical cancer natural history and HPV, adjusted for data in Spain. Self-sampling device uses in this trial is Evalyn Brush from Rovers and the HPV detection is COBAS 4800 from Roche.

Full description

Women aged 30-65 years regular user of cervical cancer screening, not pregnant and with no history of cervical disease are recruited at the cervical cancer screening clinics. Women are recruited in two Spanish distant areas, Catalonia with participant clinics in Cerdanyola del Vallés, Barberà del Vallés, Ripollet, Badia del Vallés and Sabadell, and the Canary Islands, including the clinics of Arucas, Gáldar, Prudencio Guzmán, Telde, Vecindario, Maspalomas. In both areas the cervical cancer screening was free of charge, opportunistic with cytology as primary test. Women who agreed to participate in the study signs an informed consent and are provided with a short questionnaire including sociodemographic and screening history information. Women are randomised, as they came to the screening visit, in two groups: Training group: The trained provider shows the woman how to use the self-sampling device and asks her to collect her self-sample immediately after, at the health centre. Then, the provider gives her a new device to take a new sample at home and send it back to the health center in a month time. No prior training group: The health provider shows the woman how to use self-sampling device and gives the woman a device for her to take a sample at home in a month interval and send it back to the health center. Before the process of self-sampling, women proceed with the clinical regular screening visit. The professional collects a liquid based cervical sample. An aliquot of the sample is used for cervical cytology (screening sample) and aliquot for HPV detection (study professional sample) using the Cobas system drom Roche The provider uses the clinical visit to explain the self-sampling process. Afterwards women in training group proceed to take her vaginal sample. In both groups a cervibrush is given for home self-sampling, together with written and picture-based instructions on how to obtain the sample and an acceptability questionnaire. After one month from the screening visit, women are requested to return the self-collected sample together with the questionnaire in person to the recruitment centre (acceptability questionnaire). Information available for each women includes date of birth, nationality, country of birth, educational level, marital status, work, family responsibilities and data on their previous history of cervical cancer screening as if they ever did a cytology, the result of the last cytology and number of screening tests lifetime (sociodemographic questionnaire). Also, among the women who collects the self-sampling there was available information about questions on acceptability and practicalities of sampling procedures (acceptability questionnaire). The project was approved by the ethical committees of the Bellvitge University Hospital (number PR223/17), IDIAP Jordi Gol (number P18/099) and Maternal and Child Insular University Hospital Complex (number 2018-178-1). Any information regarding the identification of patients is anonymized before analysis. The self-sample is collected using the Rovers Medical Devices Evalyn Brush from Rovers. Detection of HPV of all the samples from Catalonia is carried out at the Infections and Cancer laboratory of the Catalan Institute of Oncology in Barcelona, while those from the Canary Islands is processed in the Pathological Anatomy Service of the Maternal and Child Insular University Hospital Complex of Las Palmas de Gran Canaria. All the samples are processed using Cobas HPV test Roche Cobas 4800 HPV test. Cobas HPV test is an in-vitro quantitative detection technique for high-risk HPV DNA by polymerase chain reaction (PCR) amplification and can detect a total of 14 HR-HPV subtypes and provides the results of HPV 16 and HPV 18, and the pooled results of the other 12 subtypes in the assay. Data from both sociodemographic and acceptability questionnaires and test results (clinical and self-sampling) are collected using Research Electronic Data Capture call REDCap tools hosted at Catalan Institute of Oncology. REDCap is a secure, web-based software platform designed to support data capture for research studies, providing 1) an intuitive interface for validated data capture; 2) audit trails for tracking data manipulation and export procedures; 3) automated export procedures for seamless data downloads to common statistical packages; and 4) procedures for data integration and interoperability with external sources. Personal involved in the project had access to the REDCap platform through a username and password and enter data of each woman who has been anonymized.
