ABSTRACT
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 of the patients (55%) had metastases at the time of presentation, with 36% in stage III and 19% in stage IV. Cohorts were distributed as 2005-2006 (n = 171), 2010-2011 (n = 223), and 2017-2018 (n = 190). No immunotherapy was used. Cohort C exhibited the most significant increase in stage IV diagnoses (12.3%, 15.7%, 28.4%, respectively; p < 0.01). The median overall survival rates at the three-year follow-up demonstrated a decline over the years for stages II (97%, 98%, 57%, respectively; p < 0.05) and III (66%, 77%, 37%; p < 0.01). CONCLUSIONS: There has been a worsening in the incidence of late-stage metastatic melanoma in Peru throughout the years, coupled with a significant decline in overall survival rates. This is underscored by the fact that half of the population lives in regions devoid of oncological access.

Se revisaron los registros de 211 pacientes con lesiones no palpables sometidos a cirugía en el año 2010 en el Instituto Nacional de Enfermedades Neoplásicas. La edad promedio del grupo fue 50.82 años, 41.2% eran pre menopausicas y 57,8% post menopausicas, 20.4%(43 pacientes) tenían antecedente familiar de cáncer de mama. 130 biopsias (61.6%) fueron realizadas bajo guía ecográfica, 41(19.4%) guiadas por mamografía (arpón) y 40 (19%) correspondieron a resección de conductos terminales. 168 procedimientos (79.6%) fueron realizadas en cirugía menor con anestesia local, 24 procedimientos (11,4%)en sala de operaciones con anestesia general y 19 (9%) en cirugía menor con sedación. Se diagnosticaron 37 casos de cáncer (17,5% del total de casos registrados en la serie). 23 de los cuales fueron sometidos a cirugía de conservación y 8 a tratamiento radical.
We reviewed the records of 211 patients with nonpalpable lesions underwent surgery in 2010 at the Peruvian National Cancer Institute. The average age group was 50.82 years, 41.2% were premenopausal and postmenopausal 57.8%, 20.4% (43 patients) had family history of breast cancer. 130 biopsies (61.6%) were performed under ultrasound guidance, 41 (19.4%) guided by mammography (Howpkins needle) and 40 (19%) were terminal duct resection. 168 procedures (79.6%) were performed in minor surgery under local anesthesia, 24 procedures (11.4%) in the operating room under general anesthesia and 19 (9%) in minor surgery with sedation. We diagnosed 37 cases of cancer (17.5% of total cases in the series). 23 of whom underwent conservation surgery and 8 radical treatment.

El carcinoma de células escamosas de la piel constituyen aproximadamente el 20% de los casos de cáncer de piel. Los objetivos de este estudio fueron determinar la frecuencia de carcinoma de células escamosas de la piel de tronco y las extremidades, el cálculo de la supervivencia global y determinar los factores que influyen en el pronóstico.

En el año 2005 se diagnosticaron 814 casos de cáncer de mama de los cuales 470 casos correspondieron a cáncer de mama localmente avanzado, la edad promedio fue 53 años; 159 pacientes tuvieron manejo quirúrgico durante este mismo año, a 119 se les realizó mastectomía radical modificada y a 40 pacientes cirugía de conservación. De las 40 pacientes sometidas a cirugía de conservación, 20 recibieron quimioterapia neoadyuvante y 4 hormonoterapia neoadyuvante, la respuesta patológica valorada a través de Miller y Payne fue completa en 8 pacientes (33%), 2 pacientes presentaron progresión de enfermedad: una a nivel cerebral y la otra a nivel pulmonar. Con un seguimiento a 5 años, 27 pacientes (67,5%) se encuentran vivas sin evidencia de enfermedad, 9 pacientes (22,5%) figuran como perdidas de vista, 2 pacientes (5%) fallecieron (1 por progresión de enfermedad y otra a causa de un accidente de tránsito); 1 paciente continuó tratamiento en otra institución.
In 2005 were diagnosed 814 cases of breast cancer of which 470 cases were locally advanced breast cancer, the average age was 53 years; 159 patients had surgical management during this year, 119 underwent radical modified mastectomy and 40 had breast conservation surgery. Of the 40 patients undergoing conservation surgery, 20 received neoadjuvant chemotherapy and 4 neoadjuvant hormone therapy, the pathological response assessed by Miller and Payne was complete in 8 patients (33%), 2 patients experienced disease progression: 1 patient had cerebral metastases and the other lung metastases. With 5 years follow up, 27 patients (67.5%) are alive without evidence of disease, 9 patients (22.5%) appear lost to follow up, 2 patients (5%) died (1 for progression disease and another because of a traffic accident), 1 patient continued treatment at another institution.
