RESUMO

BACKGROUND: Recursive Partitioning Analysis (RPA) is a very flexible non parametric algorithm that allows classification of individuals according to certain criteria, particularly in clinical trials, the method is used to predict response to treatment or classify individuals according to prognostic factors. OBJECTIVES: In this paper we examine how often RPA is used in clinical trials and in meta-analysis. METHODS: We reviewed abstracts published between 1990 and 2016, and extracted data regarding clinical trial phase, year of publication, type of treatment, medical indication and main evaluated endpoints. RESULTS: One hundred and eighty three studies were identified; of these 43 were meta-analyses and 23 were clinical trials. Most of the studies were published between 2011 and 2016, for both clinical trials and meta-analyses of randomized clinical trials. The prediction of overall survival and progression free survival were the outcomes most evaluated, at 43.5% and 51.2% respectively. Regarding the use of RPA in clinical trials, the brain was the most common site studied, while for meta-analytic studies, other cancer sites were also studied. The combination of chemotherapy and radiation was seen frequently in clinical trials. CONCLUSION: Recursive partitioning analysis is a very easy technique to use, and it could be a very powerful tool to predict response in different subgroups of patients, although it is not widely used in clinical trials.

RESUMO

En Cuba, el cáncer de pulmón es el segundo en incidencia y el primero en mortalidad. Por tanto, se necesita identificar nuevas opciones terapéuticas. Los enfoques inmunológicos son interesantes debido al potencial de actividad sin las toxicidades de la quimioterapia convencional. El Centro de Inmunología Molecular generó una vacuna denominada Racotumomab, la cual actúa sobre el carcinoma pulmonar, aumentando la apoptosis tumoral y disminuyendo la cantidad de vasos tumorales. Para evaluar su seguridad se realizó un estudio de acceso expandido, multicéntrico y abierto en 86 pacientes con cáncer de pulmón de células no pequeñas. La dosis administrada fue de 1 mg/mL por vía intradérmica. Las cinco primeras dosis se administraron cada 14 días y las restantes 10 cada 28 días, hasta completar el año de tratamiento. Las reinmunizaciones durante el seguimiento fueron cada 28 días. Se analizó la aparición de los eventos adversos y se clasificaron acorde con los criterios de la CTC v4.02. Estos se reportaron en 58 pacientes (67,4por ciento), para un total de 215 eventos; el más frecuente fue el ardor en el sitio de la inyección, 32 (14,9 por ciento). El uso de la vacuna en los pacientes estudiados evidenció buen nivel de seguridad y tolerancia(AU)


In Cuba, lung cancer ranks second in incidence and first in mortality. Therefore, it is necessary to identify new therapeutical options. Immunological approaches are interesting because of the potential activity without the toxicities of conventional chemotherapy. The Center of Molecular Immunology developed a vaccine called Racotumomab; it acts on the lung carcinoma inducing an increase in tumor apoptosis and a decrease in the number of tumor vessels. A expanded access, multicenter, open study was conducted in 86 patients with non-small cell lung cancer in order to assess its safety. The administered dose was 1 mg/mL intradermically. The first 5 doses were administered every 14 days and the remaining 10 every 28 days until completing the treatment. The follow-up re immunizations were every 28 days. The occurrence of adverse events (AE) was analyzed and they were classified according to CTC v4.02 criteria. Adverse events were reported by 58 patients (67.4 percent, making a total of 215 events. burning at the injection site was the most frequently reported event, 32 (14.9 percent). The use of the vaccine in the patients under study showed good safety and tolerance(AU)

RESUMO

Ensayo Clínico Fase II-III, controlado, monocéntrico, a doble ciegas y aleatorizado, para evaluar la eficacia y seguridad del tratamiento con EPO Sin/Albúmina con un nuevo estabilizante y determinar la equivalencia terapéutica de esta formulación con el ior® EPOCIM, en enfermos hemodializados. Se incluyeron 60 pacientes, en hemodiálisis iterada 3 veces por semana, Kt/V mayor 1.2, los que mantuvieran niveles iguales o superiores de 10 g/l de Hemoglobina durante al menos 3 meses, tratados con ior Ò EPOCIM, divididos en 2 grupos, con 30 pacientes cada uno. El primero, recibió con EPO S/A la dosis habitual de Eritropoyetina y el segundo, con ior® EPOCIM, ambos por vía subcutánea en dosis 1:1 sin modificación de la dosis, evaluando la respuesta hematológica (hemoglobina/ hematocrito) de ambos productos. Los grupos de tratamiento fueron homogéneos, según las variables analizadas: la edad media para el grupo EPO SA fue de 43.8 años, mientras para el grupo ior® EPOCIM fue de 46.8 años; la media del peso seco fue de 61.1 Kg vs. 60.4 Kg. La dosis de Eritropoyetina administrada solo fue variada en dependencia del cambio de peso del enfermo entre la dosis al inicio y al final de las 12 semanas: EPO S/A 7482.9 vs. 7485.4 UI/Kg/semanal y ior â EPOCIM 8045.3 vs. 8018.6 UI/Kg/semanal. Los resultados iniciales del hematocrito (35.9 por ciento vs. 36.6 por ciento) y de la hemoglobina (11.6 vs. 11.7 g/dl) mostraron que las medias del hematocrito, para ambos grupos, al final del estudio, tuvieron una diferencia inferior a 3 por ciento (33.8 vs. 34.5) y en la hemoglobina inferior a 1 g/dl (10.6 vs. 10.7), con una disminución ligera al final del tratamiento similar para ambos grupos. Los eventos adversos detectados fueron: dolor en el sitio de la inyección (63 por ciento), hipotensión (53.3 por ciento), calambre (31.7 por ciento ) y cefaleas (15 por ciento ) atribuibles al proceder de hemodiálisis, con un perfil de seguridad propio de enfermos en hemodiálisis. No se observaro......(AU)


A randomized, double blind, controlled, monocentric Clinical Trial Phase II-III is conducted to establish the efficacy and security of the treatment with EPO without/albumin with a new stabilizer and determine the equivalence of this formulation with the ior® EPOCIM in hemodyalized patients. 60 patients were included in iterated hemodyalisis 3 times per week, Kt/V >1,2, those who kept similar or superior levels of 10g/L of Hemoglobin during at least, for 3 months, treated with ior® EPOCIM divided in 2 groups , of 30 patients each. The first, received an EPO W/A, habitual dose of erythropoietin and the second with ior® EPOCIM, both administered s/c in doses of 1:1, no modifications in doses, evaluating the hematological response (hemoglobin, CBC) in both products. The treatment groups were homogeneous, according to the variables: for the group EPO W/A: mean age was 43.8 years, while for the group ior® EPOCIM was 46, 8 years. The media of the dry weight was of a 61,1KG vs. 60, 4 KG. Doses of erythropoietin varied only in dependence with the weight changes of the patient at the beginning and at the end of the 12 weeks. EPO W/A 7482.9 vs.7485.4 U/KG/week and ior® EPOCIM 8045.3 vs. 8018.6 UI/KG/week. Initial results of the CBC (35, 9 percent vs. 36,6 percent ) and hemoglobin (11,6 vs. 11,7 g/dl) showed that medias of CBC for both groups at the end of the study had a difference inferior to 3 percent ( 33,8 vs. 34,5) and in hemoglobin , inferior to 1 g/dl (10,6 vs. 10,7), with a slight decrease at the end of the treatment for both groups. The detected adverse effects were: pain in the site of the injection, (63 percent) hypotension (53, 3 percent ), cramps (31, 7 percent) and headaches (15 percent), all attributable to the hemodyalisis process with a profile very similar to all the patients undergoing hemodyalisis. There were no statistical differences among the groups (p=0.5938). The results allow suggest the equivalence of this new product to establish its ....(AU)
