The prognostic value of sentinel lymph node micrometastases in patients with invasive breast carcinoma
2016
The prognostic value of sentinel lymph node micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients.We have retrospectively analyzed 746 patients with operable invasive breast cancer and clinically negative axillary lymph nodes. These patients underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Patients with micrometastases in the sentinel lymph node treated with axillary dissection has been checked and the involvement of the remaining lymph nodes analyzed. Patients with micrometastases in th…
New methods to improve the safety assessment of cryopreserved ovarian tissue for fertility preservation in breast cancer patients
2015
Objective To develop a novel molecular panel of markers to detect breast cancer (BC) disseminated malignant cells in ovarian tissue, and to improve the safety of ovarian tissue transplantation. Design Experimental study. Setting University hospital. Patient(s) Ten ovarian biopsies from healthy patients, 13 biopsies with diagnosed BC metastasis, and 4 biopsies from primary BC tumor for designing a diagnostic panel of BC cell contamination; 60 ovarian biopsies from BC patients undergoing fertility preservation for validating the panel. Animal(s) Female nude mice. Intervention(s) A novel panel for BC malignant cell detection by reverse-transcription polymerase chain reaction (RT-PCR), inmmunoh…
Detection of lymph node metastases in esophageal cancer.
2011
Lymph node status is the most important single prognostic factor in esophageal cancer. The detection of involved lymph nodes is therefore the key to cure. This article will provide a meta-analysis and metaregression analysis on the diagnostic performances of current lymph node-detection devices; discuss the recent status of the sentinel lymph node concept in esophageal cancer by the two sentinel node-mapping procedures (the radio-guided and the blue dye techniques) and the developing computed tomography (CT) lymphography; discuss the detection of micrometastases; and the potential clinical application of molecular-based patients' profiles. Combined use of endoscopic ultrasonography fine-nee…
Estudio del papel de la EMT y las vías de control inmunológico en las micrometástasis moleculares detectadas en ganglio centinela de pacientes con ca…

En los últimos años se ha incrementado el uso de técnicas de biología molecular para mejorar el diagnóstico y conocer mejor la etiología del CP (cáncer pulmonar), debido a que la posibilidad de padecerlo ha sido definida como la interrelación entre la exposición a carcinógenos ambientales y la susceptibilidad individual determinada genéticamente (D’Amico et al., 1999). Dicha susceptibilidad genética es la que resulta determinante para entender por qué, siendo el tabaco responsable de más del 90% de los CP en el hombre y del 80% en la mujer, sólo un 11-12% de los fumadores desarrollan un cáncer (Kratz et al., 2012). Sin embargo, comprender qué factores genéticos determinan una mayor propensi…
