Repercussions of the COVID-19 pandemic on breast cancer actions in a Brazilian state.

Objective: To analyze whether the COVID-19 pandemic had an impact on the screening, diagnosis and treatment of breast cancer in women up to 50 years of age in the state of Pará. Methods: Retrospective, cross-sectional study with a quantitative approach, using data from the Information Technology Department of the Brazilian Unified Health System. (DATASUS). The number of exams carried out in the pre-pandemic (2018-2019) and pandemic (2020-2021) period was analyzed based on the percentage variation, application of the chi-square test and G test for the time of exams and start time of treatment. Results: During the pandemic period, there was a greater number of screening mammograms (+3.68%), cytological (+23.68%), histological (+10.7%) and a lower number of diagnostic mammograms (-38.7%). The time interval for carrying out the exams was up to 30 days for screening and diagnostic exams and more than 60 days to start treatment during the pandemic period. Conclusion: Although the results indicate an increase in the number of screening and diagnostic procedures for breast cancer during the pandemic period, with the exception of diagnostic mammography, when considering probability values, the study points out that statistically the COVID-19 pandemic did not interfere with actions of breast cancer, in women over 50 years of age, in the state of Pará. Considering the autonomy of nursing and its role in public health, it is up to the professionals who are in charge of primary care programs to implement contingency plans in periods of crisis so that the population is not left unassisted.

Objetivo. Analizar si la pandemia de COVID-19 tuvo impacto en el tamizaje, diagnóstico y tratamiento del cáncer de mama en mujeres de 50 años y más del Estado do Pará-Brasil. Métodos. Estudio retrospectivo, transversal, con abordaje cuantitativo, en el que se utilizaron los datos del Departamento de Informática del Sistema Único de Salud de Brasil (DATASUS). Se comparó el número de exámenes realizados y el tiempo para el inicio de tratamiento en los períodos prepandémico (2018-2019) y pandémico (2020-2021). Resultados. Se observó un mayor número de mamografías de cribado (+3.68%), citologías (+23.68%) e histologías (+10.7%) y un menor número de mamografías diagnósticas (-38.7%) en el período pandémico. El tiempo para la realización de las pruebas fue de hasta 30 días para el cribado y diagnóstico y de más de 60 días para el inicio del tratamiento durante el período pandémico. Conclusión. Aunque los resultados indican un aumento del número de procedimientos de cribado y diagnóstico del cáncer de mama en el periodo pandémico, con la excepción de la mamografía diagnóstica, cuando consideramos los valores de p) el estudio muestra que la pandemia COVID-19 estadísticamente no interfirió en las acciones preventivas contra el cáncer de mama en mujeres de 50 años y más en el estado de Pará. Teniendo en cuenta la autonomía de la enfermería y su papel en la salud pública, corresponde a los profesionales responsables de los programas de atención primaria implementar planes de contingencia en tiempos de crisis para no dejar desatendida a la población.

Real-World Evidence on the Use of Endocrine Therapy for Ductal Carcinoma In Situ in Patients Treated With Breast-Conserving Surgery Followed by Postoperative Radiation Therapy: A Brazilian Retrospective Cohort Study.

INTRODUCTION/BACKGROUND: This study aims to evaluate the reproducibility of findings from randomized controlled trials regarding adjuvant hormone therapy (HT) for breast ductal carcinoma in situ (DCIS) in a real-life scenario. MATERIALS/METHODS: This retrospective cohort study used Fundação Oncocentro de São Paulo database. It included DCIS patients DCIS who received breast-conserving surgery and postoperative radiation therapy. The endpoints were local control (LC), breast cancer-specific survival (BCSS), and overall survival (OS). RESULTS: We analyzed 2192 patients treated between 2000 and 2020. The median FU was 48.99 months. Most patients (53.33%; n = 1169) received adjuvant HT. Patients not receiving adjuvant HT tend to be older (P = .021) and have a lower educational level (P < .001). At the end of FU, 1.5% of patients had local recurrence, and there was no significant difference between groups (P = .19). The 10-year OS and BCSS were 89.4% and 97.5% for adjuvant HT versus 91.5% and 98.5% for no adjuvant HT, respectively, and there were no significant differences between groups. The 10-year OS was 93.25% for medium/high education level versus 87.31% for low (HR for death 0.51; 95% CI, 0.32-0.83; P = .007). CONCLUSIONS: The benefits of adjuvant HT for DCIS were not reproduced in a Brazilian cohort. Education significantly impacted survival and HT usage, reflecting the influence of socioeconomic factors. These findings can allow for more precise interventions.

Collagen content and C-X-C motif chemokine ligand 12 expression in neoplastic breast stroma

SUMMARY OBJECTIVE: This study aimed to evaluate the expression of C-X-C motif chemokine ligand 12 and its C-X-C chemokine receptor type 4, and the tumor-stroma ratio using collagen stromal content of breast cancer samples, correlating it with clinicopathological data. METHODS: Through a retrospective cohort study, samples were obtained from female patients, over 18 years of age, with the disease in stages 1-4, who underwent mastectomy or lumpectomy. The biopsies were provided by the Oncology sector of the Hospital das Clínicas of Universidade Federal de Pernambuco, Recife city, in 2011-2014, including samples of invasive ductal carcinoma, ductal carcinoma in situ, or benign changes (fibroadenoma and hypertrophy), which were analyzed between 2020 and 2022 by immunohistochemistry for the expression of stromal cell characteristics. Collagen content was tested by Gomori staining and digital analysis of images. RESULTS: Absence of stromal expression of C-X-C motif chemokine ligand 12 was associated with longer disease-free survival (disease-free survival=0.481), and expression of C-X-C chemokine receptor type 4 was associated with lower disease-free survival. An association was observed between clinicopathological variables and stromal expression of chemokines, that is, an association of stromal C-X-C motif chemokine ligand 12 with histological grade, angiolymphatic invasion, and an association between C-X-C chemokine receptor type 4 expression and histological grade. Analyses of digital pixels images of collagen and tumor cells showed a lower percentage of collagen in the invasive ductal carcinoma samples (39%), unlike samples without neoplasms (78%). CONCLUSION: Low expression of C-X-C motif chemokine ligand 12 may be associated with a worse prognosis for breast cancer. Collagen staining analyzed using digital images represents an opportunity for clinical application and is indicative of the prognosis of the tumor microenvironment in breast carcinoma.

Resumen OBJETIVOS: Determinar la utilidad del afeitado de la cavidad de la cuadrantectomía por cáncer de mama en la reducción de reoperación y explorar sus factores asociados y describir las características sociodemográficas y clínicas de las pacientes. MATERIALES Y MÉTODOS: Estudio de cohorte, retrospectivo y descriptivo efectuado entre el 1 enero de 2017 y el 31 de diciembre de 2018 en pacientes mayores de 18 años con diagnóstico histológico de carcinoma invasivo e in situ de mama a quienes se practicó cuadrantectomía con afeitado de todos los márgenes de la cavidad. Se trata del registro de las pacientes de un cirujano de Medellín, Colombia. Se recopilaron datos demográficos, clínicos, paraclínicos y se analizaron con estadística descriptiva. RESULTADOS: Se incluyeron 194 pacientes con edad media de 61.6 años. Los márgenes fueron negativos en el 85.6% (n = 161) y positivos en el 14.4% (n = 28). La cavidad afeitada estaba afectada en el 16% (n = 31), no se requirió reintervención en el 95.9% (n = 186) y se reintervinieron 4.1% (n = 8). La reducción de la reintervención fue del 10.3% (n = 20%). Los factores asociados con márgenes positivos fueron: marcación con arpón (OR = 1.19; IC95%: 1.07-1,32; p = 0.04), tumor multifocal (OR = 3.95; IC95%: 2.29-6.81; p = 0.00), afeitado afectado (OR = 3.26; IC95%: 1.75-6.04). Entre los grupos no se encontró mayor riesgo de recurrencia local (OR = 0.85; IC95%: 0.80-0.90; p = 0.35). CONCLUSIONES: El afeitado de todos los márgenes de la cavidad de la cuadrantectomía tuvo una reducción en la tasa de márgenes afectados y disminución de las reintervenciones. Los factores asociados con márgenes positivos fueron: marcación con arpón, tumor multifocal y el daño del afeitado; no hubo mayor riesgo de recurrencia.

Abstract OBJECTIVES: To determine the usefulness of quadrantectomy cavity shaving for breast cancer in reducing reoperation and to explore its associated factors and describe sociodemographic and clinical data of the patients. MATERIALS AND METHODS: A retrospective, descriptive, retrospective cohort study conducted between January 1, 2017 and December 31, 2018 in patients older than 18 years with histologic diagnosis of invasive and in situ breast cancer who underwent quadrantectomy with shaving of all cavity margins. This is the registry of patients of a surgeon in Medellin, Colombia. Demographic, clinical, and paraclinical data were collected and analyzed using descriptive statistics. RESULTS: 194 patients with a mean age of 61.6 years were included. The margins were negative in 85.6% (n = 161) and positive in 14.4% (n = 28). The shaved cavity was involved in 16% (n = 31), no reintervention was required in 95.9% (n = 186), and 4.1% (n = 8) underwent reintervention. The reduction in reoperation was 10.3% (n=20). Factors associated with positive margins were: harpoon marking (OR = 1.19; 95%CI: 1.07-1.32; p = 0.04), multifocal tumor (OR = 3.95; 95%CI: 2.29-6.81; p = 0.00), affected shave (OR = 3.26; 95%CI: 1.75-6.04). No increased risk of local recurrence was found between groups (OR = 0.85; 95%CI: 0.80-0.90; p = 0.35). CONCLUSIONS: Shaving all margins of the quadrantectomy cavity was associated with a lower rate of involved margins and fewer reinterventions. Factors associated with positive margins were: harpoon marking, multifocal tumor, and shave damage; there was no increased risk of recurrence.

Low-grade carcinoma in situ in fibroadenoma: a case report

Fibroadenomas are the most common benign breast neoplasms. In rare cases, a carcinoma may develop within a fibroadenoma. The aim of this study was to report a case of low-grade carcinoma in situ in a fibroadenoma. A 31-year-old female, G0P0A0 and without family history of cancer, arrives at the service with an expressive breast lump growth along the year year. Core biopsy, histopathological and immunohistochemical studies showed an in-situ carcinoma in a fibroadenoma. Surgical resection was performed with a safety margin, and anatomopathological study and immunohistochemistry of the surgical specimen confirmed the core biopsy diagnosis. Currently, the patient is under annual clinical follow-up with mammography and breast ultrasound and no evidence of neoplastic disease. Although this is a rare event and few cases are described in the literature, carcinomas in situ can occur in a fibroadenoma.
