Introduction: The worldwide incidence of melanoma has increased in the last 40 years. Our aim was to describe the clinic-pathological characteristics and outcomes of three cohorts of patients diagnosed with melanoma in a Latin-American cancer institute during the last 20 years. Methods: We evaluated three retrospective patient cohorts diagnosed with melanoma at Instituto Nacional de Enfermedades Neoplasicas (INEN), a public hospital in Lima, Peru, for the years 2005–2006, 2010–2011, and 2017–2018. Survival rate differences were assessed using the Log-rank test. Results: Overall, 584 patients were included (only trunk and extremities); 51% were male, the mean age was 61 (3–97) years, and 48% of patients resided in rural areas. The mean time to diagnosis was 22.6 months, and the mean Breslow thickness was 7.4 mm (T4). Lower extremity was the most common location (72%). A majority o...

Introduction: Breast pathology is a very common reason for medical attention. Tissue diagnosis is usually obtained with core needle biopsy which could be performed by breast surgeons or interventional radiologists. Our aim was to assess the comparison of diagnostic performance between the two services. Methods: A retrospective, descriptive and cross-sectional study was carried out on patients who had breast pathology at Instituto Nacional de Enfermedades Neoplasicas in 2019. Descriptive analyses, sensitivity and specificity were calculated using the R program version 4.2.3. Results: From 1,082 patients with breast tumours who underwent core needle biopsy (CNB) during 2019, 782 cases were included. Breast surgeons performed 462 CNBs and radiologists performed 320 CNBs. The 87.5% were palpable tumours and 525 breast carcinomas were identified in the final pathology. The diagnostic performa...

Background: Tranexamic acid (TXA) has demonstrated promising outcomes in plastic surgery. Our aim was to assess the effect of TXA in intraoperative bleeding, operative time, and complications among patients undergoing facial surgical procedures. Methods: A retrospective cohort study of patients who underwent multiplane facial rhytidectomy from January 2018 to September 2022 at the Clinica Ziegler, Lima, Peru. Patients were divided into two groups according to the use of intravenous plus local infiltration of TXA. We performed the chi square test to assess associations among categorical variables, the Student t test and Mann-Whitney U test for categorical with continuous variables, and Pearson correlation for quantitative variables. Results: A total of 100 patients were included with 50 patients in each group. The median age was 59.5 years and the majority were women (88%). The median ope...

La cirugía endoscópica ha permitido realizar múltiples tipos de abordajes mínimamente invasivos, incluyendo, actualmente, la cirugía de mamas, una técnica común en países asiáticos. Dentro de las opciones quirúrgicas se incluye la cirugía preservadora de piel y pezón por puerto único, la cual es reportada como oncológicamente segura y bien tolerada. Se presenta el primer reporte en Perú sobre esta cirugía en una paciente con cáncer de mama tratado con neoadyuvancia, donde describimos la técnica quirúrgica y los resultados anatomopatológicos y estéticos.
