Análise comparativa da reconstrução mamária imediata e tardia no tratamento do câncer de mama em um hospital público do Distrito Federal

Abstract

This is an observational, cross-sectional, and analytical study, carried out through the analysis of electronic medical records from the TrackCare® platform of participants treated with mastectomy with immediate and delayed reconstruction. All women diagnosed with Breast Cancer and/or mutated treated at the Mastology and Plastic Surgery outpatient clinic of the Hospital Regional da Asa Norte belonging to the State Department of Health of the Federal District (HRAN/SES/DF), during the period of March 2015 to December 2022. 577 were treated surgically. Of these, 401 underwent radical surgery (mastectomies). The remaining 176 women underwent conservative surgery. 192 mastectomized women undergoing reconstruction were recruited. There was a total sample loss of 27 participants due to metastases, death, lack of data or refusal to respond to the survey. The final sample of this research was composed of 165 women who met the study's eligibility criteria and responded to the Breast-Q® questionnaire validated for Portuguese, to assess satisfaction and quality of life related to breast reconstruction, from the perspective of the patient. Breast-Q® total scores (2.0) were rescaled to 0-100 using the non-linear Rasch transformation method. The average scores of the satisfaction and well-being indicators were compared between participants using the Student's t test, for the indicators that had a Gaussian distribution. If the indicators did not present a Gaussian distribution, the comparison was made using the non-parametric Mann- Whitney test. The results presented were given as mean ± standard deviation. The associations between quantitative demographic or clinical variables with the group were evaluated using the Student's t test or non-parametric Mann-Whitney test and for those qualitative variables the Chi-square or exact Chi-square test was used. The association between clinical staging and group was assessed using the Cochran-Armitage trend test. The analyzes were carried out using the SAS 9.4 program. P < 0.05 was considered significant.
