Interacción de los antineoplásicos orales con los alimentos: revisión sistemática
2009
Victor.Jimenez@uv.es Introducción: Los estudios de biodisponibilidad son parte integrante del desarrollo clínico de medicamentos para administración oral con el fin de identificar potenciales interacciones fármaco-alimento (iFA). Actualmente, para los antineoplásicos orales se empieza a reconocer su importancia clínica, aun cuando lamentablemente, la información disponible presenta variabilidad en su evidencia científica. Objetivos: Revisar la evidencia científica disponible sobre las interacciones de los alimentos con medicamentos antineoplásicos orales y establecer recomendaciones para su administración. Métodos: Se realizó una búsqueda bibliográfica en Medline y The Cochrane Library para…
Prognostic and predictive value of primary tumour side in patients with RAS wild-type metastatic colorectal cancer treated with chemotherapy and EGFR…
2017
BACKGROUND: There is increasing evidence that metastatic colorectal cancer (mCRC) is a genetically heterogeneous disease and that tumours arising from different sides of the colon (left versus right) have different clinical outcomes. Furthermore, previous analyses comparing the activity of different classes of targeted agents in patients with KRAS wild-type (wt) or RAS wt mCRC suggest that primary tumour location (side), might be both prognostic and predictive for clinical outcome. METHODS: This retrospective analysis investigated the prognostic and predictive influence of the localization of the primary tumour in patients with unresectable RAS wt mCRC included in six randomized trials (CRY…
Antitumor activity of ipatasertib combined with chemotherapy: results from a phase Ib study in solid tumors
2020
Inhibidor d'AKT; Càncer avançat; Fase I Inhibidor de AKT; Cáncer avanzado; Fase I AKT inhibitor; Advanced cancer; Phase I Background This phase Ib study evaluated the safety, tolerability, pharmacokinetics, and preliminary efficacy of the oral AKT inhibitor ipatasertib and chemotherapy or hormonal therapy in patients with advanced or metastatic solid tumors to determine combined dose-limiting toxicities (DLTs), maximum tolerated dose, and recommended phase II doses and schedules. Patients and methods The clinical study comprised four combination treatment arms: arm A (with docetaxel), arm B [with mFOLFOX6 (modified leucovorin, 5-fluorouracil, and oxaliplatin)], arm C (with paclitaxel), and …
Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…
2013
Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…
Relevancia de la autofagia en la toxicidad de los antiinflamatorios no esteroideos sobre el epitelio digestivo
2017
Los antiinflamatorios no esteroideos (AINE) constituyen uno de los grupos de medicamentos más consumidos en el mundo por sus acciones antiinflamatoria, analgésica y antipirética, y, en consecuencia, sus reacciones adversas tienen una gran repercusión en la población. Su mecanismo de acción consiste en la inhibición de las enzimas ciclooxigenasas y el consecuente descenso en los niveles de prostanoides. Si la implicación de estos mediadores en la inflamación, el dolor y la fiebre justifica las acciones farmacológicas, su rol en funciones fisiológicas explica su perfil de efectos secundarios. Entre sus reacciones adversas merecen una mención especial las que ocurren a nivel gastrointestinal, …
Central nervous system involvement at first relapse in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycl…
2009
Background The prevalence of and risk factors for central nervous system recurrence in patients with acute promyelocytic leukemia are not well established and remain a controversial matter. Design and Methods Between 1996 and 2005, 739 patients with newly diagnosed acute promyelocytic leukemia enrolled in two consecutive trials (PETHEMA LPA96 and LPA99) received induction therapy-with all-trans retinoic acid and idarubicin. Consolidation therapy comprised three courses of anthracycline monochemotherapy (LPA96), with all-trans retinoic acid and reinforced doses of idarubicin in patients with an intermediate or high risk of relapse (LPA99). Central nervous system prophylaxis was not given. Re…
Detection of MET Alterations Using Cell Free DNA and Circulating Tumor Cells from Cancer Patients
2020
MET alterations may provide a potential biomarker to evaluate patients who will benefit from treatment with MET inhibitors. Therefore, the purpose of the present study is to investigate the utility of a liquid biopsy-based strategy to assess MET alterations in cancer patients. We analyzed MET amplification in circulating free DNA (cfDNA) from 174 patients with cancer and 49 healthy controls and demonstrated the accuracy of the analysis to detect its alteration in patients. Importantly, a significant correlation between cfDNA concentration and MET copy number (CN) in cancer patients (r = 0.57, p <
Estudio farmacogenético del tratamiento del cáncer de mama basado en antraciclinas y taxanos
2016
Existe una importante variabilidad interindividual en la respuesta a los medicamentos que condiciona que no sea fácil predecir la efectividad o seguridad de un fármaco en un paciente concreto. La Farmacogenética (PGt) estudia el vínculo entre las variaciones en la secuencia de ADN de un paciente y su respuesta al tratamiento farmacológico. La variación de un único nucleótido puede tener consecuencias dramáticas, de modo que la identificación de variantes que alteren la función o expresión de las proteínas implicadas en la farmacocinética o farmacodinamia y su efecto final sobre la respuesta es el objetivo de la PGt. El Cáncer de Mama (CM) es el tipo de cáncer más frecuente en mujeres. A pes…
The oral KIF11 inhibitor 4SC‐205 exhibits antitumor activity and potentiates standard and targeted therapies in primary and metastatic neuroblastoma …
2021
Inhibidor de KIF11; Terapias dirigidas; Metástasis Inhibidor de KIF11; Teràpies dirigides; Metàstasi KIF11 inhibitor; Targeted therapies; Metastasis In summary, our study provides a rationale for the future therapeutic integration in clinical trials of 4SC-205, an structurally distinct oral KIF11 inhibitor that shows potent antitumor activity in multiple preclinical neuroblastoma models and sensitizes neuroblastoma cells to standard chemotherapy and specific neuroblastoma-targeted therapies. The financial support for this research was provided by Instituto de Salud Calos III (PI20/00530 to Miguel F. Segura; PI20/01107 to Rosa Noguera; PI17/02248 and CPII18/00027 to Anna Santamaria; PI19/013…
