Functional and transcriptomic characterization of carboplatin-resistant A2780 ovarian cancer cell line

Biol. Res; 52 (), 2019
BACKGROUND: Ovarian cancer is a significant cancer-related cause of death in women worldwide. The most used chemotherapeutic regimen is based on carboplatin (CBDCA). However, CBDCA resistance is the main obstacle to a better prognosis. An in vitro drug-resistant cell model would help in the understanding...

Carcinoma de ovario en paciente con mutación del gen BRCA1. Diagnóstico tras biopsia de adenopatía cervical, en el contexto de un síndrome paraneoplásico cutáneo
Ovarian carcinoma in a patient with a BRCA1 gene mutation. Diagnosis after biopsy of cervical adenopathy, in the context of a cutaneous paraneoplastic syndrome

RESUMEN El cáncer epitelial de ovario representa uno de los tumores ginecológicos más letales ya que más del 75% de las pacientes son diagnosticadas en estadío avanzado. Aún no se ha demostrado que la realización de pruebas y exámenes pélvicos rutinarios haya reducido la mortalidad, no existiend...

Cost effectiveness of the cancer prevention program for carriers of the BRCA1/2 mutation

ABSTRACT OBJECTIVE: To analyze the cost effectiveness of the diagnostic program for the germline mutation in BRCA1/2 genes and of preventative strategies for the relatives of patients diagnosed with ovarian cancer associated with this mutation. METHODS: The study analyzed the cost effectiveness by deve...

Homologous recombination deficiency in ovarian cancer: a review of its epidemiology and management

Clinics; 73 (supl.1), 2018
Ovarian cancer patients with homologous recombination deficiencies exhibit specific clinical behaviors, and improved responses to treatments, such as platinum-based chemotherapy and poly (ADP-ribose) polymerase (PARP) inhibitors, have been observed. Germline mutations in the BRCA 1/2 genes are the most w...

Relationship between matrix metalloproteinases and the occurrence and development of ovarian cancer

Braz. j. med. biol. res; 50 (6), 2017
Ovarian cancer is one of the most malignant genital cancers, with a high mortality rate. Many researchers have suggested that matrix metalloproteinases (MMPs) have remarkably high expression in ovarian cancer tissues. MMPs are considered to be related to the occurrence, development, invasion and metastas...

Circulating tumor cells as a new and additional approach to follow-up patients with serous low-grade ovarian adenocarcinoma: a case report and review of the literature

Appl. cancer res; 37 (), 2017
Background: Current methods for follow-up of Ovarian Cancer (OC) are widespread, especially with CA125, which, however, is not a perfect biomarker and thus further investigation for new methods of evaluation are warranted. The feasibility of Circulating Tumor Cells (CTCs) in advanced OC was investigated ...

Mutations in BRCA1, BRCA2 and other breast and ovarian cancer susceptibility genes in Central and South American populations

Biol. Res; 50 (), 2017
Breast cancer (BC) is the most common malignancy among women worldwide. A major advance in the understanding of the genetic etiology of BC was the discovery of BRCA1 and BRCA2 (BRCA1/2) genes, which are considered high-penetrance BC genes. In non-carriers of BRCA1/2 mutations, disease susceptibility may ...

Câncer de ovário

Objetivos: O câncer de ovário (CO) apresenta grande impacto na taxa de mortalidade por neoplasias ginecológicas no mundo. No Brasil, apresenta incidência estimada de 5,95 casos para cada 100.000 mulheres. Esta revisão tem por objetivo reunir as principais informações sobre a neoplasia maligna ovar...

Cáncer serosopélvico de alto grado: evidencia sobre su origen en la trompa de Falopio
High-grade serous pelvic cancer: evidence of its origin in the fallopian tube

Cáncer epitelial de ovario es una enfermedad altamente letal. Constituye la quinta causa de muerte por cáncer en mujeres a nivel mundial. El subtipo histológico más frecuente es el carcinoma seroso de alto grado. Este es el responsable de la alta letalidad de la enfermedad. Se presenta evidencia que ...

Mutaciones del gen RAD51 en el cáncer familiar de ovario: revisión de la literatura
RAD51 gene mutations in familial ovarian cancer: literature review

ANTECEDENTES: En los últimos 15 años, el carcinoma familiar de ovario, ha sido atribuido en su mayoría a mutaciones en BRCA 1 y 2. Sin embargo, aproximadamente el 25% de los nuevos casos se asocian a mutaciones aisladas de genes implicados en el mecanismo de reparación del ADN por recombinación hom...
