ABSTRACT

Resumen Introducción: Existen múltiples factores pronóstico de la supervivencia en el cáncer de mama metastásico (CMM). Los dos factores mejor estudiados son la expresión de receptores hormonales (RH) y el estatus HER2, por lo que su determinación es obligada en toda paciente con diagnóstico de CMM. El 80% de los tumores expresan RH y el 20% son HER2-positivo. El objetivo de este estudio es determinar los factores pronóstico de la supervivencia global (SG) de pacientes con diagnóstico de CMM HER2-positivo atendidos entre 2009 y 2015 en el Instituto de Cancerología de Medellín (Colombia). Métodos: Estudio observacional retrospectivo. Se realizaron las curvas de supervivencia mediante el método de Kaplan-Meier comparadas con Log-Rank test y se analizaron los factores que influyeron en la supervivencia mediante la regresión de Cox. Resultados: Se incluyeron 101 pacientes. La mediana de seguimiento fue 46,6 meses (rango 13-155 meses), la SG a cinco años fue 41% (IC95%: 31%-50%) y a diez años 13% (IC95%: 4%-30%). Tuvieron mayor SG pacientes con enfermedad en recaída, con estadios I y II, las mayores de 40 años, menopáusicas, con tumores con grado histológico bajo y co-expresión de receptores hormonales. Las pacientes que recayeron tuvieron mayor SG que las que hicieron metástasis de novo (HR: 0,47, IC95%: 0,27-0,81) ajustado por las otras variables. Conclusiones: La supervivencia de estas pacientes fue semejante al de otros países, al igual que las líneas de tratamiento y la terapia recibida.


Abstract Introduction: There are multiple risk factors associated with the prognosis of survival of metastatic breast cancer (MBC). The two major risk factors are the expression of hormonal receptors (HR) and HER 2 neu, and the reason why they are requested in every MBC patient. The large majority (80%) of breast tumors are HR positive, and 20% are HER 2 positive. The aim of this study was to determine the prognostic factors associated with the overall survival (OS) of patients diagnosed with HER 2 positive MBC seen between January 2009 and December 2015 in the Instituto de Cancerología (Medellín-Colombia). Methods: A retrospective observational study was conducted, with survival analysis using the Kaplan-Meier method. The survival curves were compared using the Log-Rank Test, and factors associated with survival were analyzed using the Cox regression. Results: 101 patients were included in the study. The median survival time was 46.6 months (Range 13-155 months), the 5-year OS was 41% (95% CI; 31%-50%) and the 10-year OS 13% (95% CI; 4%-30%). Higher overall survival was found for patients with relapsed disease, those with stages I and II, patients older than 40 years, postmenopausal, tumors with low histological grade and with co-expression of hormonal receptors. The patients with relapse of disease had a higher OS than the de novo patients after being adjusted for the other factors (HR: 0.47, 95% CI; 0.27-0.1). Discussion: The overall survival time is similar to that of other countries, as well as the lines of treatment and therapy received.

ABSTRACT

Isla del Coco is an oceanic island 500km off the Pacific coast of Costa Rica. It is a National Park and its marine fauna has been relatively well protected. The island is famous for its elasmobranch (sharks, rays and skates) sightings in shallow waters. Here we present a catalogue of the deepwater elasmobranchs observed with the DeepSee submersible. Five species of sharks, six species of skates and one ray have been observed between 45 and 330m depth. Triaenodon obesus, the white tip reef shark, was commonly observed between 80 and 301m, but only in the afternoons. Sphyrna lewini, the scalloped hammerhead shark, was observed as deep a 303m, but commonly between 45 and 90m, and close to the island. Odontaspis ferox, the smalltooth sand tiger shark, was observed between 82 and 316m. Echinorhinus cookei, the prickly shark, was observed between 91 and 320m. Rhincodon typus, the whale shark, was observed only close to the island, between 77 and 80m. Taeniura meyeni, the marbled ray, was observed only close to the island, between 45 and 90m. A Dasyatis sp., similar to the the diamond stingray, was observed only once close to the island at 60m; this is the first report of this genus at Isla del Coco National Park. Manta birostris, the giant manta, was only observed close to the island at 90m. Mobula tarapacana, the sicklefin devil ray, was observed between 60 and 326m, extending its maximum depth almost 10 times what has been reported. Aetobatus narinari, the spotted eagle ray, was observed only close to the island between 60 and 82m. Torpedo peruana, the Peruvian torpedo ray, was observed only once at 313m, and is the first record of this species from Isla del Coco National Park.


La Isla del Coco es una isla oceánica a 500km de la costa Pacífica de Costa Rica. Es un Parque Nacional donde la fauna marina ha estado relativamente bien protegida. La isla es famosa por los elasmobranquios (tiburones y rayas) en aguas poco profundas. Aquí presentamos un catálogo de elasmobranquios observados con el sumergible DeepSee. Cinco especies de tiburones y siete especies de rayas han sido observadas entre 45 y 330m de profundidad. Triaenodon obesus, tiburón punta blanca de arrecifes o tiburón cazón coralero, observado comúnmente entre 80 y 301m pero solo en las tardes. Sphyrna lewini, el tiburón martillo o cornuda común, registrado hasta 303m, pero comúnmente entre 45 y 90m, y cerca de la Isla del Coco. Odontaspis ferox, tiburón solrayo, visto entre 82 y 316m. Echinorhinus cookei, tiburón negro espinoso, avistado entre 91 y 320m. Rhincodon typus, tiburón ballena, observado solamente cerca de la isla, entre 77 y 80m. Taeniura meyeni, raya moteada, vista solamente cerca de la isla, entre 45 y 90m. Dasyatis sp., parecida a la raya látigo, registrada solamente una vez, cerca de la isla a 60m; este es el primer informe de esta especie en el Parque Nacional Isla del Coco. Manta birostris, manta gigante, observada únicamente cerca de la isla a 90m. Mobula tarapacana, manta cornuda o manta moruma, vista entre 60 y 326m, extendiendo su profundidad máxima casi 10 veces a lo informado en la literatura. Aetobatus narinari, chucho pintado o raya águila, observada solamente cerca de la isla entre 60 y 82m. Por último, Torpedo peruana, raya torpedo eléctrico o raya peruana, solamente vista una vez a 313m y es el primer informe de esta especie en el Parque Nacional Isla del Coco.
