ABSTRACT

ABSTRACT Background: Tyrosine kinase inhibitors (TKI) and immunotherapy improved survival in metastatic renal cell carcinoma (mRCC). Disparities in treatment access are present in healthcare systems globally. The aim of this study was to analyze survival outcomes of mRCC patients treated with first-line TKIs in the public (PHS) and private (PrS) health system in a Brazilian Cancer Center. Materials and Methods: Records from all mRCC patients treated with first-line TKIs from 2007-2018 were reviewed retrospectively. Categorial variables were compared by Fisher's exact test. Survival was estimated by Kaplan-Maier method and survival curves were compared using the log-rank test. Prognostic factors were adjusted by Cox regression model. Results: Of the 171 eligible patients, 37 (21.6%) were PHS patients and 134 (78.4%) were PrS patients. There were no difference in age, gender, or sites of metastasis. PHS patients had worse performance status (ECOG ≥2, 35.1% vs. 13.5%, p=0.007), poorer risk score (IMDC poor risk, 32.4% vs. 16.4%, p=0.09), and less nephrectomies (73% vs. 92.5%, p=0.003) than PrS patients. Median lines of therapy was one for PHS versus two for PrS patients (p=0.03). Median overall survival (OS) was 16.5 versus 26.5 months (p=0.002) and progression-free survival (PFS), 8.4 versus 11 months (p=0.01) for PHS and PrS patients, respectively. After adjusting for known prognostic factors on multivariate analysis, PHS patients still had a higher risk of death (HR: 1.61, 95% CI: 1.01-2.56, p=0.047). Conclusion: Patients with mRCC treated via the PHS had worse overall survival, possibly due to poorer prognosis at presentation and less drug access.

ABSTRACT

According to data from studies, antioxidant herbal compounds are, likely to have a useful role in reducing the harmful effects of environmental pollutants and toxic chemicals that most people are exposed to. Cadmium is one of the toxic elements that accumulate in many organs, especially in kidneys. The aim of this study was to investigate the effect of crocin on the expression of PKHD1 and KLLN genes in cadmium-treated rats.In this experimental study, 40 adults male Wistar rats (200-250 g) were randomly divided into the following groups: control group received normal saline, cadmium group (15mg/kg), crocin group (20mg/kg) and cadmium group daily fed with crocin at a dose of 20 mg/kg.After eight weeks of treatment, rats were dissected, and kidney tissues were removed for evaluation of PKHD1 and KLLN gene expression by real time method. The data were analyzed using one-way ANOVA and significant difference between groups was P<0.05.Our results showed an increase in PKHD1 gene expression and a decrease in KLLN gene expression in kidney tissue in the cadmium group compared to the control group (P <0.001).Also, a significant decrease in PKHD1 gene expression (P <0.001) and an increase in KLLN gene expression P <0.05) were observed in the tissues of all cadmium-treated rats compared to cadmium.Crocin consumption can have a protective effect against the impaired expression of PKHD1 and KLLN cadmium-induced apoptotic pathway.


Diversos estudios sugieren que compuestos antioxidantes de hierbas tienen un papel útil en la reducción de los efectos nocivos de los contaminantes ambientales y los químicos tóxicos a los que está expuesta la mayoría de las personas. El cadmio es uno de los elementos tóxicos que se acumulan en muchos órganos, especialmente en los riñones. El objetivo de este estudio fue investigar el efecto de la crocina en la expresión de los genes PKHD1 y KLLN en ratas tratadas con cadmio.En este estudio experimental, 40 ratas Wistar macho adultas (200-250 g) se dividieron aleatoriamente en los siguientes grupos: el grupo de control recibió solución salina normal, el grupo de cadmio (15 mg / kg), el grupo de crocina (20 mg / kg) y el grupo de cadmio alimentado diariamente con crocina a una dosis de 20 mg / kg.Después de ocho semanas de tratamiento, se disecaron las ratas y se extrajeron los tejidos renales para evaluar la expresión de los genes PKHD1 y KLLN mediante un método en tiempo real. Los datos se analizaron mediante ANOVA de una vía y la diferencia significativa entre los grupos fue P <0,05.Nuestros resultados mostraron un aumento en la expresión del gen PKHD1 y una disminución en la expresión del gen KLLN en el tejido renal en el grupo de cadmio en comparación con el grupo de control (P <0,001).Además, se observó una disminución significativa en la expresión del gen PKHD1 (P <0,001) y un aumento en la expresión del gen KLLN P <0,05) en los tejidos de todas las ratas tratadas con cadmio en comparación con el cadmio.El consumo de crocina puede tener un efecto protector contra la expresión alterada de la vía apoptótica inducida por cadmio PKHD1 y KLLN.

ABSTRACT

El Tumor de Wilms (TW) es el tumor renal más frecuente entre los 1 y 5 años de edad. La evidencia existente respecto de aspectos clínicos, terapéuticos y de supervivencia (SV) del TW es escasa. El objetivo de este estudio fue determinar diferencias en la SV actuarial global (SVAG) y SV libre de enfermedad (SVLE) a 5 años en pacientes con TW tratados con quimioterapia neoadyuvante (QTNA) y cirugía inicial (CI). Serie de casos. Se incluyeron pacientes con TW de 11 meses y 13 años de edad, tratados en el Instituto del Cáncer SOLCA, Cuenca (1994-2019). Las variables resultado fueron SVAG y SVLE a 5 años. Otras variables de interés fueron: localización, estadio, histología, seguimiento y remisión completa (RC). Una vez concluidos sus tratamientos, los pacientes fueron sometidos a un seguimiento clínico. Se utilizó estadística descriptiva (medidas de tendencia central y dispersión) y analítica (Chi2, exacto de Fisher y corrección por continuidad). Se realizaron análisis de SV con curvas de Kaplan Meier y log-rank. Se reclutaron 36 pacientes (52,8 % hombres), con una mediana de edad de 44 meses; 55,5 % de ellos tuvieron histología favorable. La localización y estadio más frecuente fue riñón izquierdo (55,5 %) y I (33,3 %) respectivamente. El 58,3 % fueron sometidos a CI y el 41,7 % QTNA. Luego de aplicados los tratamientos 21 pacientes (58,3 %), alcanzaron RC. La SVAG y SVLE general a 5 años fue 72,0 % y 69,0 % respectivamente. Al comparar los subgrupos con QTNA y CI; se verificaron SVAG y SVLE a 5 años de 60,0 % y 81,0 % (p=0,118); y de 66,7 % y 71,4 % (p=0,536) respectivamente. La SVAG y SVLE verificadas son similares a las reportadas en otros estudios. No se evidenciaron diferencias de éstas con los tratamientos QTNA y CI.


Wilms tumor (WT) is the most common pediatric kidney tumor between 1 and 5 years of age. The existing evidence regarding clinical, therapeutic and survival (SV) aspects of TW is scarce. The aim of this study was to determine differences in 5-year overall survival (OS) and 5-year disease-free survival (DFS), in patients treated by WT with neoadjuvant chemotherapy (NACT) and initial surgery (IS). Case series. Patients with TW between 11 months and 13 years of age, treated at SOLCA Cancer Institute, Cuenca, Ecuador (1994-2019) were included. The outcome variables were OS and DFS. Once their treatments were completed, patients were followed clinically. Descriptive (measures of central tendency and dispersion) and analytical (Chi2, Fisher's exact and continuity correction) statistics were applied. SV analysis with Kaplan Meier curves and log-rank were performed. 36 patients (52.8 % men), with a median age of 44 months; 55.5 % of which had favorable histology were recruited. The most frequent location and stage was left kidney (55.5 %) and I (33.3 %) respectively. 58.3 % underwent IC and 41.7 % QTNA. After treatments, 21 patients (58.3 %) achieved complete remission. General OS and DFS were 72.0 % and 69.0 % respectively. When comparing subgroups with QTNA and CI. When comparing the subgroups with QTNA and CI, OS and DFS of 60.0 % and 81.0 % were verified (p=0.118); and of 66.7 % and 71.4 % (p=0.536) respectively. General OS and DFS observed are similar to those reported in other studies. No differences were evidenced with QTNA and CI treatments.

ABSTRACT

ABSTRACT Purpose: To explore the potential association between renal mass characteristics and a history of chemotherapy. Materials and methods: A retrospective review of records of patients surgically treated for a localized renal mass between 2000 and 2012 was undertaken following an institutional review board approval. Patients age and sex, renal mass clinical characteristics (radiological size and mode of presentation) and pathological characteristics (diagnosis, renal cell carcinoma subtype, Fuhrman grade and stage) were compared between patients with and without a history of chemotherapy, using Fisher's exact test, Student's t-test and Wilcoxon rank sum test. A multivariate logistic analysis was performed to evaluate the independent association of chemotherapy and tumor pathology. Results: Of the 1,038 eligible patients, 33 (3%) had a history of chemotherapy. The distribution of clinical stage, renal mass diagnosis, renal cell carcinoma subtype, Fuhrman grade, pathological stage, sex and median age were similar between the general population and the chemotherapy group. However, the latter had a higher rate of incidental presentation (P = 0.003) and a significantly smaller median radiological tumor size (P = 0.01). In a subset analysis of T1a renal cell carcinoma, the chemotherapy group presented an increased rate of high Fuhrman grade (P = 0.03). On multivariate analysis adjusted for radiological tumor size, sex and age the chemotherapy cohort had a 3.92 higher odds for high Fuhrman grade. Conclusion: Patients with a history of chemotherapy typically present with smaller renal masses that, if malignant, have higher odds of harboring a high Fuhrman grade and thus may not be suitable for active surveillance.

ABSTRACT

ABSTRACT Purpose: To elucidate the prognostic value of systemic inflammatory response in patients with metastatic renal cell carcinoma (mRCC) who are treated with sunitinib, we evaluated the prognostic role of C-reactive protein (CRP) kinetics. This study also compared prognostic models containing CRP kinetics and neutrophil-to-lymphocyte ratio (NLR) kinetics. Materials and Methods: A consecutive cohort of 94 patients with mRCC who were treated with sunitinib was retrospectively included from Fudan University Shanghai Cancer Center. According to dynamic changes in CRP and the NLR, patients were divided into three groups for analysis of CRP and NLR kinetics. The associations between survival and potential prognostic factors were assessed. The incremental value of prognostication was evaluated. Results: A significant difference (P<0.001) in overall survival (OS) was observed among the three groups of CRP kinetics. The median OS of the non-elevated group was nearly 1.3-fold longer than that of the normalized group (33.0 vs. 26.3 months), and two times longer than that of the non-normalized group (33.0 vs. 14.0 months). Multivariate analysis showed that CRP and NLR kinetics were independent prognostic indicators. The model containing CRP kinetics had a better predictive accuracy than that with NLR kinetics, which was supported by the C-index (0.731 vs. 0.684) and the likelihood ratio χ2 test (79.9% vs. 44.9%). Conclusion: Our study suggests that dynamic changes in CRP can better predict survival in patients with mRCC who are treated with sunitinib. Routine assessment of CRP before and after targeted therapy would help identify patients at risk of a poor outcome.

ABSTRACT

Resumo: O câncer renal é a 13ª neoplasia mais frequente no mundo. Entre 2012 e 2016, representou 1,48% das mortes por câncer no Brasil. A terapia de escolha para o tratamento de câncer renal metastático são os inibidores de tirosina quinase (ITK), sunitinibe e pazopanibe. Este artigo avalia o custo-efetividade do pazopanibe comparado ao sunitinibe no tratamento de câncer renal metastático. Foi realizada uma análise de custo-efetividade sob a perspectiva de um hospital federal do Sistema Único de Saúde. No modelo de árvore de decisão foram aplicados os desfechos de efetividade e segurança dos ITK. Os dados clínicos foram extraídos de prontuários e os custos diretos consultados em fontes oficiais do Ministério da Saúde. O custo de 10 meses de tratamento, englobando o valor dos ITK, procedimentos e manejo de eventos adversos, foi de R$ 98.677,19 para o pazopanibe e R$ 155.227,11 para o sunitinibe. Os medicamentos apresentaram efetividade estatisticamente equivalente e diferença estatisticamente significativa para o desfecho de segurança, no qual o pazopanibe obteve o melhor resultado. O pazopanibe, nesse contexto, é a tecnologia dominante quando os custos de tratamento são associados aos de manejo de eventos adversos.


Abstract: Renal cancer is the 13th most frequent neoplasm in the world. From 2010 to 2014, renal cancer accounted for 1.43% of cancer deaths in Brazil. The treatment of choice for metastatic renal cancer is tyrosine kinase inhibitors (TKI) sunitinib and pazopanib. This article assesses cost-effectiveness between pazopanib and sunitinib in the treatment of metastatic renal cancer. A cost-effectiveness study was performed from the perspective of a federal hospital under the Brazilian Unified National Health System (SUS). TKI effectiveness and safety outcomes were applied to the decision tree model. Clinical data were extracted from patient charts, and direct costs were consulted from official Ministry of Health sources. The cost of 10 months of treatment, including the costs of the TKI, procedures and management of adverse events, was BRL 98,677.19 for pazopanib and BRL 155,227.11 for sunitinib. The drugs displayed statistically equivalent effectiveness and statistically different safety outcomes, with pazopanib displaying better results. In this setting, pazopanib is the dominant technology when the treatment costs are analyzed together with the costs of managing adverse events.

ABSTRACT

Introdução: O câncer merece destaque entre as doenças que causam transtornos em adultos e crianças, pois continua sendo um diagnóstico dos mais temidos da atualidade. Vincula-se a um estigma de sofrimento, mutilação e morte, envolvendo uma série de ameaças e dificuldades, que afetam não só a criança, mas sua família como um todo, ao longo do processo de diagnóstico e tratamento Objetivo: Comparar os comportamentos de crianças durante a quimioterapia endovenosa antes e após a aplicação do brinquedo terapêutico instrucional (BTI). Materiais e Métodos: Pesquisa não controlada do tipo "antes e depois", realizada na oncopediatria de um hospital público. Foram avaliadas 10 crianças submetidas a quimioterapia endovenosa. Na coleta de dados, utilizou-se um questionário com questões sociodemográficas, clínicas, comportamentais e reações esboçadas durante o tratamento, antes e após a sessão de BTI. A análise de dados foi feita no programa SPSS, sendo realizado o teste de Mc Nemar, considerando um intervalo de confiança de 95%. Resultados: O câncer infantil mais frequente foi a Leucemia Linfoide Aguda (40%). Dos comportamentos analisados, percebeuse redução significativa após o uso do BTI do comportamento "postura retraída". Conclusão: O BTI representou uma ferramenta importante no controle da ansiedade e sofrimento gerado pelo tratamento quimioterápico endovenoso.


Introduction: Cancer plays a notable role among diseases that afflict adults and children. Its diagnosis is still much feared and connects to a stigma of suffering, mutilation and death. It is related to difficulties and treats that affects not only the child but also his whole family during the long process of diagnosis and treatment. Objective: to compare the behaviors of children during intravenous chemotherapy before and after the application of therapeutic instructional toy (BTI). Materials and methods: Uncontrolled search such as "before and after", held in oncopediatria of a public hospital. Ten children were evaluated, subjected to intravenous chemotherapy. For collection, it was used a questionnaire asking for sociodemographic, clinical and behavioral questions, as well as issues and reactions outlined during treatment, before and after the session of BTI. The data analysis was done in SPSS program, being carried out the Mc Nemar test, assuming a confidence interval of 95%. Results: the most frequent childhood cancer was Acute Lymphoblastic leukemia (40%). Among the behaviors examined, it was significantly reduced after the use of BTI "retracted posture" behavior. Conclusion: the BTI represented an important tool in the control of anxiety and suffering generated by intravenous chemotherapy treatment.

ABSTRACT

Introduction: Wilms' tumor is a malignant renal neoplasm that frequently occurs in children during the first decade of life. clinically, it is a rapidly growing abdominal mass that causes low back pain and hematuria. computerized axial tomography or nuclear magnetic resonance are fundamental for its diagnosis, and chemotherapy and surgery have become first-choice treatments. after diagnosis, the majority of treatment plans involve the administration of antineoplastic drugs, whose side effects may include mucositis, candidiasis, xerostomia, caries, and worsen other previously diagnosed lesions, regardless of the organ affected by the tumor. treatment is more effective if provided by a multidisciplinary team in which the dentist plays a significant role in the implementation of an integral oral care protocol. in the present study, the management of a pediatric patient under antineoplastic treatment for Wilms' tumor is reported. case report: a four-year-old female patient diagnosed with Wilms' tumor, who required antineoplastic treatment. she had temporary dentition with early childhood caries, irreversible pulpal lesions and agenesis of teeth 72, 82, and the germ of tooth 42. the patient received modeling based behavior management therapy, prophylactic oral hygiene, and restoration of teeth affected by caries. to present this case, the "CARE" guidelines were used. conclusion: poor oral health status prior to cancer therapy directly affects the quality of life and the treatment of a patient, increasing the risks of local or systemic infections. as such evaluation and dental treatment before antineoplastic therapy is important to prevent oral complications and lesions.

ABSTRACT

ABSTRACT We conducted a systematic review and meta-analysis of the literature on the efficacy of the targeted therapies in the treatment of advanced RCC and, via an indirect comparison, to provide an optimal treatment among these agents. A systematic search of Medline, Scopus, Cochrane Library and Clinical Trials unpublished was performed up to Jan 1, 2015 to identify eligible randomized trials. Outcomes of interest assessing a targeted agent included progression free survival (PFS), overall survival (OS) and objective response rate (ORR). Thirty eligible randomized controlled studies, total twentyfourth trails (5110 cases and 4626 controls) were identified. Compared with placebo and IFN-α, single vascular epithelial growth factor (receptor) tyrosine kinase inhibitor and mammalian target of rapamycin agent (VEGF(r)-TKI & mTOR inhibitor) were associated with improved PFS, improved OS and higher ORR, respectively. Comparing sorafenib combination vs sorafenib, there was no significant difference with regard to PFS and OS, but with a higher ORR. Comparing single or combination VEGF(r)-TKI & mTOR inhibitor vs BEV + IFN-α, there was no significant difference with regard to PFS, OS, or ORR. Our network ITC meta-analysis also indicated a superior PFS of axitinib and everolimus compared to sorafenib. Our data suggest that targeted therapy with VEGF(r)-TKI & mTOR inhibitor is associated with superior efficacy for treating advanced RCC with improved PFS, OS and higher ORR compared to placebo and IFN-α. In summary, here we give a comprehensive overview of current targeted therapies of advanced RCC that may provide evidence for the adequate targeted therapy selecting.

ABSTRACT

OBJECTIVE@#To determine whether chloroquine (CQ), an often used inhibitor of late autophagy and autophagosome/lyosome fusion, can inhibit proliferation of renal carcinoma cells and investigate its effect on sunitinib (ST)-induced apoptosis.@*METHODS@#Renal carcinoma cell line 786 O and ACHN had been used as cellular model and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS) assay was carried out to detect the cell viability in response to CQ or ST treatment. Both transmission electron microscope and immunoblotting had been employed to observe apoptotic and autophagic process. To examine the involvement of autophagy in ST-dependent apoptosis, autophagy had been inhibited either chemically or genetically via utilizing autophagy inhibitor or specific small interference RNA (siRNA) targeted to either Ulk1 (unc-51-like kinase 1) or LC3 (microtubule associated protein 1 light chain 3 fusion protein), two essential autophagic proteins.@*RESULTS@#Both ST and CQ induced cell viability loss, indicating that either of them could inhibit renal cancer cell proliferation. Clone formation experiments confirmed the aforementioned results. Furthermore, the combined ST with CQ synergistically promoted the loss of cell viability. By transmission electron microscopy and immunoblotting, we found that the ST induced both autophagy and caspase-dependent apoptosis. While 3-MA, an early autophagy inhibitor, reduced the ST-induced cleavage of poly (ADP-ribose) polymerase-1 (PARP-1), a substrate of caspase 3/7 and often used marker of caspase-dependent apoptosis, CQ promoted the ST-dependent PARP-1 cleavage, indicating that the early and late autophagy functioned differentially on the ST-activated apoptotic process. Moreover, the knock down of either Ulk1 or LC3 decreased the ST-caused apoptosis.Interestingly, we observed that rapamycin, a specific inhibitor of mTOR (mammalian target of rapamycin) and an inducer of autophagy, also showed to inhibit cell viability and increased the cleavage of PARP-1 in the ST-treated cells, suggesting that autophagy was likely to play a dual role in the regulation of the ST-induced apoptosis.@*CONCLUSION@#ST activates both apoptotic and autophagic process in renal carcinoma cells. Although autophagy precedes the ST-induced apoptosis, however, early and late autophagy functions differentially on the apoptotic process induced by this compound. Additionally, ST can coordinate with the inducer of autophagy to inhibit the cell proliferation. Further research in this direction will let us illuminate to utilize CQ as a potential drug in the treatment of renal carcinoma.

ABSTRACT

Presentamos un paciente de 63 años con cáncer renal y aumento de fosfatasa alcalina sérica de tipo óseo de acuerdo con su reactividad con anticuerpos monoclonales específicos. Se descartaron las causas conocidas de aumento de la isoenzima, incluyendo metástasis óseas. Los niveles enzimáticos cayeron abruptamente con la remoción del tumor, por lo que consideramos a este último como su origen. Diversas isoenzimas de fosfatasa alcalina pueden ser producidas y secretadas por tumores como manifestación paraneoplásica. El conocimiento de esto puede, en ocasiones, orientarnos hacia la presencia de una neoplasia oculta. Además, los cambios en los niveles séricos de esas isoenzimas pueden ser indicadores de respuesta al tratamiento o de recidiva tumoral. (AU)


A 63-year old man was seen in the outpatient clinic because of renal cancer and elevation in bone alkaline phosphatase measured by monoclonal antibodies assay. Known causes of bone isoenzyme augmentation, including bone metastases, were ruled out. The tumoral origin of the isoenzyme was diagnosed because after removal of the tumor the enzymatic levels fell sharply. Several alkaline phosphatase isoenzymes can be produced and secreted by tumors as a paraneoplasic manifestation and their elevation could be a manifestation of an occult neoplasia. Furthermore the monitoring of their blood levels can be useful means of treatment response and a tool to monitoring recurrence if a sharp decrease after removal of the tumor is observed. (AU)

ABSTRACT

INTRODUCCIÓN: Antecedentes: El presente dictamen expone la evaluación de la eficacia y seguridad del medicamento everolimuspara el tratamiento de pacientes adultos con cácner renal metastásico de células claras que han progresado al tratamiento de primera línea con inhibidores de la tirosina quinasa. Aspectos Generales: El carcinoma de células renames (CCR), es cual se origina dentro de la corteza renal, es el tipo más frecuente de cáncer de rinón en adultos, representando hasta el 90% de todos éstos. Tecnología Sanitaria de Interés: Everolimus: Everolimus es un inhibidor selectivo de la vía del mTOR. La mTOR es una serinatreonina-quinasa que participa en el control de la división celular y la dilatación de los vasos sanguíneos. Everolimus se une a una proteína denominada FKBP-12 presente en el interior de las células formando un complejo que inhibe la actividad del complejo mTOR. Su mecanismo de acción consiste en el bloqueo del crecimiento y proliferación de las células neoplásicas, la reducción de la angiogénesis (formación de vasos que suministran sangre al tumor) y la modificación del metabolismo celular llevando a la interrupción de la división celular y la autodestrucción de la misma. METODOLOGÍA: Estrategia de Búsqueda: Se realizó una busqueda sistemática de la evidencia cientifica, especialmente la proveniente de ensayos clínicos, con respecto a la eficacia y seguridad de everolimus para el tratamiento de segunda línea en pacientes adultos con diagnóstico de CCR metastásico de células claras, en las bases de datos PUBMED y TRIPDATABASE. Se realizó una busqueda dentro de bases de datos pertenecientes a grupos que realizan revisiones sistemáticas, evaluación de tecnologías sanitarias y guías de práctica clínica. RESULTADOS: Sinopsis de la Evidencia: Se realizó una búsqueda de la literatura con respecto a la eficacia y seguridad de everolimus como tratamiento de pacientes adultos con cáncer renal metastásico de células claras que han progresado al tratamiento de primera línea con inhibidores de la tirosina quinasa. CONCLUSIONES: El presente documento evaluó la evidencia científica publicada hasta enero del 2017 sobre la eficacia y seguridad de everolimus, en comparación a la mejor terapia de soporte o placebo, para el tratamiento de pacientes adultos con cáncer renal metastásico de células claras que han progresado al tratamiento de primera línea con inhibidores de la tirosina quinasa. El Instituto de Evalución de Tecnologías en Salud e Investigación (IETSI) no aprueba el uso de everolimus para el tratamiento de pacientes adultos con cáncer renal metastásico de células claras que han progresado al tratamiento de primera línea con inhibidores de la tirosina quinasa.

ABSTRACT

INTRODUCCIÓN: El Cáncer Renal (CR) representa el 2-3% de los cánceres del adulto a nivel mundial, presentando la mayor incidencia en los países occidentales. En 2014, se estimó que habría 63.920 casos nuevos de cáncer de riñón en EEUU, con 13.860 muertes estimadas por esta enfermedad y una tasa de sobrevida global a 5 años de aproximadamente el 70%. En Chile, según el Primer Informe de Registros Poblacionales la tasa de incidencia al 2012 fue de 6,9 x 100.000 hab., y la tasa general de mortalidad el año 2011 de 3,8 x 100.000 hab. Según el Departamento de Estadísticas e Información en Salud (DEIS) del MINSAL, el año 2011 se produjeron 657 fallecidos por esta causa, 401 hombres y 256 mujeres, con una relación Hombre: Mujer de 1,57:1. La tasa de mortalidad general va en ascenso: 2,7 x 100.000 el año 1997 v/s 3,8 en el año 2011. En cuanto a su histología, más de 90% de los cánceres de riñón surgen en el parénquima renal (siendo la mayoría carcinomas de células renales), y el resto en la pelvis renal. Antes de 2005, el tratamiento se limitaba a citoquinas terapia con IL-2 o IFN-a, cuya eficacia era limitada y de alta toxicidad. Este informe evalúa sunitinib, pazopanib y axintinib para pacientes con CR avanzado o metastásico de células claras en pacientes aptos para recibir inmunoterapia. TECNOLOGÍAS SANITARIAS ANALIZADAS: Sunitinib (SUTENT®); Pazopanib (VOTRIENT®, VORIFAS®, KIPANIB®, INOXTAR®); Axitinib (INYTA®). EFICACIA DE LOS TRATAMIENTOS: Se encontraron seis revisiones sistemáticas relevantes que compararon el uso de pazopanib contra placebo, y que muestran el resultado de 2 Ensayos Clínicos Aleatorizados (ECAs). Además, se encontraron 2 revisiones sistemáticas con meta-análisis de redes que inclueron 20 ECAs que comparaban directa o indirectamente axitinib y sunitinib contra placebo. Pazopanib, en comparación a placebo, probablemente no tiene un efecto importante en la mortalidad de pacientes con cáncer renal metastásico, pero reduce la progresión de la enfermedad. Sunitinib, en comparación a placebo podría hacer poca o ninguna diferencia respecto de la mortalidad de pacientes con cáncer renal metastásico, mientras que podría reducir la mortalidad de pacientes con cáncer renal metastásico. Axitinib, en comparación a placebo podría reducir la mortalidad de pacientes con cáncer renal metastásico. ANÁLISIS ECONÓMICO: Las agencias de distintos países (Canadá, Inglaterra y Australia) recomiendan el uso de Sunitinib, Pazopanib y Axitinib para el tratamiento del cáncer renal metastásico. Algunas agencias (Canadá e Inglaterra) han realizado esta recomendación siempre y cuando se considere un costo razonable para estos medicamentos. En consideración se tiene también en las distintas líneas que se consideran los tratamientos. El impacto presupuestario calculado para el primer año es de MM$ 2.049 (Sunitinib), MM$2.674 (Pazopanib) y MM$1.303 (Axitinib). CONCLUSIÓN: Para dar cumplimiento al artículo 28° del Reglamento que establece el proceso destinado a determinar los diagnósticos y tratamientos de alto costo con Sistema de Protección Financiera, según lo establecido en los artículos 7°y 8° de la ley N°20.850, aprobado por el decreto N°13 del Ministerio de Salud, se concluye que el presente informe de evaluación se considera favorable para los 3 tratamientos considerados, de acuerdo a lo establecido en el Título III. de las Evaluaciones Favorables de la Norma Técnica N° 0192 de este mismo ministerio.

ABSTRACT

ABSTRACT A rapid, sensitive, and accurate high performance liquid chromatography for the determination of Axitinib (AN) in rabbit plasma is developed using crizotinibe as an internal standard (IS). Axitinib is a tyrosine kinase inhibitor, used in the treatment of advanced kidney cancer, which works by slowing or stopping the growth of cancer cells. The chromatographic separation was performed on a Waters 2695, Kromosil (150 mm × 4.6 mm, 5 µm) column using a mobile phase containing buffer (pH 4.6) and acetonitrile in the ratio of 65:35 v/v with a flow rate of1 mL/min. The analyte and internal standard were extracted using liquid-liquid extraction with acetonitrile. The elution was detected by photo diode array detector at 320 nm.The total chromatographic runtime is 10.0 min with a retention time for Axitinib and IS of 5.685, and 3.606 min, respectively. The method was validated over a dynamic linear range of 0.002-0.2µg/mL for Axitinib with a correlation coefficient of r2 0.999.

ABSTRACT

INTRODUCCIÓN: Antecedentes: El presente dictamen expone la evaluación de tecnologia de la eficacia y seguridad de sunitinib para el tratamiento de pacientes adultos con cáncer renal de células no claras (cromófobo) con enfermedad metastásica irresecable. Aspectos Generales: El carcinoma de células renales (CCR) usualmente se origina en el revestimiento de los túbulos del riñon y contiene muchos vasos sanguíneos. El CCR es el tipo más común de cáncer de riño, representando el 90% de todos los cánceres de riños y aproximadamente el 3% de todos los cánceres en adultos en Europa. Tecnología Sanitaria de Interés: Sunitinib es un fármaco antineoplásico de administración oral, que inhibe múltiples receptores de tirosina quinasa (RTKs), algunos de los cuales están implicados en el crecimiento tumoral, la neoangiogénesis y la progresión a metástasis. Estos incluyen los receptores del factor de crecimiento derivado de plaquetas (PDGFR alfa y PDGFR beta), factor de crecimiento del endotelio vascular (VEGFR1, (VEGFR2 y (VEGFR3), factor de células madre (KIT), tirosin-kinasa 3tipo Fms (FLT3), factor estimulador de colonias (CSF-1R) y factor neurotrófico derivado de la línea celular glial (RET). La inhibición simultánea de estos receptores genera una fuerte disminución de la neovascularización tumoral, conllevando así a la reducción del tumor, y a su vez explica muchos de sus efectos adversos tales como el síndrome mano pie, estomatitis, y otra variedad de efectos dermatológicos. METODOLOGÍA: Estrategia de Búsqueda: Se realizó una búsqueda sistemática de la evidencia científica, especialmente la proveniente de ensayos clínicos, con respecto a la eficacia y seguridad de sunitinib en pacientes adultos con diagnóstico de carcinoma de células renales metastásico cromófobo en las bases de datos MEDLINE, TRIPDATABASE y LILACS. Una vez identificados los artículos que respondían a la preginta PICO, se pasó a revisar la bibliografia incluida en dichos artículos seleccionados, con la finalidad de identificar evidencia adicional. Asimismo, se realizó una búsqueda dentro de bases de datos pertenecientes a grupos que realizan revisiones sistemáticas, evaluación de tecnologías sanitarias y guías de práctica clínica tales como National Comprehensive Cancer Network (NCCN), The National Guideline for Clearinghouse (NGC), Scottish Intercollegiate Guidelines Network (SIGN), The National Institute for Health and Cares Excellence (NICE), The Canadian Agency for Drugs and Technologies in Health (CADTH), The Agency for Healthcarre Research and Quality (AHQR) y The Cochrane Collaboration. Se hizo una búsqueda adicional en clinicaltrials.gov y www.ensayosclinicos-repec.ins.gob.pe, para poder identificar ensayos clínicos en curso o que no hayan sido publicados. RESULTADOS: Sinopsis de la Evidencia: Se realizó una búsqueda de la literatura con respecto a la eficacia y seguridad de sunitinib, en comparación a la mejor terpia de soporte, como tratamiento del cáncer renal de céluas no claras de tipo cromófobo con enfermedad metastásica irresecable. Debido a que no se encontraron ensayos clínicos que respondieran a la preginta PICO, se incluyeron diseños de estudios del tipo ensayos clínicos de un solo brazo, ensayos clínicos comparativos versus otras terapias dirigidas y estudios retrospectivos. CONCLUSIONES: A la fecha, no existe evidencia suficiente sobre la eficacia de sunitinib, con respecto a la mejor terpia de soporte, en pacientes adultos con diagnóstico de cáncer renal cromófobo, en términos de mayor sobrevida global, calidad de vida, sobrevida libre de progresión y tasa respuesta objetiva. El Instituto de Evaluación de Tecnologías en Salud e Investigación (IETSI) no aprueba el uso de sunitinib para el tratamiento de pacientes adultos con cáncer de células no claras (cromófobo) con enfermedad metastásica irresecable.

ABSTRACT

ABSTRACT Purpose: The aim of this study was to assess the impact of sunitinib treatment in a non-screened group of patients with metastatic renal cell cancer (mRCC) treated by the Brazilian Unified Health System (SUS) at a single reference institution. Material and Methods: Retrospective cohort study, which evaluated patients with mRCC who received sunitinib between May 2010 and December 2013. Results: Fifty-eight patients were eligible. Most patients were male 41 (71%), with a median age of 58 years. Nephrectomy was performed in 41 (71%) patients with a median interval of 16 months between the surgery and initiation of sunitinib. The most prevalent histological subtype was clear cell carcinoma, present in 52 (91.2%) patients. In 50 patients (86%), sunitinib was the first line of systemic treatment. The main adverse effects were fatigue (57%), hypothyroidism (43%), mucositis (33%) and diarrhea (29%). Grade 3 and 4 adverse effects were infrequent: fatigue (12%), hypertension (12%), thrombocytopenia (7%), neutropenia (5%) and hand-foot syndrome (5%). Forty percent of patients achieved a partial response and 35% stable disease, with a disease control rate of 75%. Median progression free survival was 7.6 months and median overall survival was 14.1 months. Conclusion: Sunitinib treatment was active in the majority of patients, especially those with low and intermediate risk by MSKCC score, with manageable toxicity. Survival rates were inferior in this non-screened population with mRCC treated in the SUS.

ABSTRACT

INTRODUCCIÓN: El Instituto de Evaluación de Tecnologías en Salud e Investigación (IETSI) recibió la\r\nsolicitud de evaluar la seguridad y eficacia del uso de axitinib en el tratamiento de pacientes con diagnóstico de cáncer renal metastásico con tratamiento previo con sunitinib dentro del sistema de EsSalud, indicación actualmente no contemplada en el petitorio farmacológico. Esta acción sigue lo estipulado en la Directiva 003-IETSI-ESSALUD-2016 (1) y el objetivo final es determinar el la seguridad y eficacia de axitinib. Tecnología Sanitaria de Interés: Axitinib (inlyta) es un compuesto químico (fórmula molecular: C22H18N40S), que inhibe la irosina quinasa actuando selectivamente sobre los receptores del factor de crecimiento endotelial vascular 1, 2 y 3, del receptor del factor de crecimiento derivado de las plaquetas, y del receptor del c-kit, promoviendo la inhibición de la angiogénesis tumoral. Como tal fue aprobado por la FDA en enero del 2012 para el tratamiento de pacientes adultos con carcinoma de células renales avanzado. METODOLOGÍA: Estrategia de Búsqueda: El protocolo de esta revisión sistemática fue preparado y revisado con el equipo técnico de IETSI. Las siguientes fuentes han sido revisadas y consultadas con la intención de buscar la mejor evidencia disponible que directamente responda a la pregunta PICO (Población, Intervención, Desenlaces clínicos primarios), de esta evaluación. RESULTADOS: En resumen, luego de revisar un total de 343 referencias resultados de la búsqueda bibliográfica, logramos filtrar 126 referencias relevantes para la pregunta PICO de interés (Tabla 1), de los cuales solo 15 referencias fueron finalmente seleccionadas para nuestro análisis toda vez que constituían referencias de estudios que respondían a la pregunta PICO de interés de este dictamen, incluyendo cuatro guías de práctica clínica, tres meta-análisis, tres evaluaciones de tecnología y cinco referencias, todas de un único ensayo clínico de fase III. CONCLUSIONES: No se ha encontrado en la presente evaluación de tecnología sanitaria evidencia consistente que establezca cual es el beneficio neto atribuible al uso de axitinib por sobre la mejor terapia de soporte o placebo en pacientes con cáncer renal metastásico que progresaron al tratamiento con sunitinib. Considerando que a la fecha se disponen ya de una gran variedad de alternativas de tratamiento de segunda línea, futuros ensayos clínicos que comparen directamente axitinib versus la más costo efectiva de estas alternativas son altamente recomendables. El Instituto de Evaluación de Tecnologías en Salud e Investigación-IETSI no aprueba el uso de axitinib como una alternativa de tratamiento para pacientes con diagnóstico de cáncer renal metastásico con tratamiento previo con sunitinib.
