Recurrence of esophageal cancer after R0 surgery: risk factors and evolution
2013
Introduction despite advances in surgical and adjuvant therapy, recurrence in esophageal cancer submitted to R0 surgery remains high. The aim is to define risk factors and recurrence patterns. Additionally, to show the management carried out and the outcome of patients showing recurrence. Material and methods observational and prospective study that included 61 patients. Neoadjuvancy therapy was indicated on T3, T4 and N+ tumors and every lymph node dissection was performed in two fields. Recurrence is defined at distance, regional or local, when, recurrence is detected after six months. According to clinical features and the recurrences, a palliative, chemotherapeutic or surgical managemen…
Impact of perioperative transfusions and sepsis on long-term oncologic outcomes after curative colon cancer resection. A retrospective analysis of a …
2020
Objective: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results.The role of IASC and blood transfusions on long-term oncologic results is still debated. This study aims to assess the impact of these two variables on survival after curative colon cancer resection. Patients and methods: Retrospective analysis of a prospectively maintained database of patients who underwent curative surgery for colon cancer at a university hospital, between 1993 and 2010. Cox regression was used to identify the role of IASC and transfusions (alone and combined) on local recurrence (LR), disea…
Adenocarcinoma colorrectal: factores pronósticos de supervivencia en el tratamiento adyuvante con 5-Fluorouracilo-Levamisol (5FU-Lev)
2004
PROPÓSITO: Valoración de la supervivencia global (SG) y libre de enfermedad (SLE) a 5 años y estudio de los factores pronósticos de los pacientes operados, con finalidad curativa, de adenocarcinoma colorrectal estadios II y III, que recibieron tratamiento adyuvante con 5FU-LEV. MATERIAL Y MÉTODOS: ciento veintiséis pacientes tratados con esquema 5FU-LEV durante 12 meses, entre septiembre de 1990 y noviembre de 1997. RESULTADOS: La SG a los 5 años es de 68.3% y la SLE de 54%. El número de ganglios afectos por el tumor y la afectación vásculo-linfática y perineural, han resultado factores pronósticos significativos tanto en la SLE como en SG a los 5 años. La existencia de obstrucción intestin…
Epulis-Like Presentation of Gingival Renal Cancer Metastasis
2017
Mouth metastatic cancers are very rare and they usually represent the evidence of a widespread disease. Common primary tumors are lung carcinoma in men and breast carcinoma in women, followed by kidney cancer. In the oral soft tissues, the gingiva is the most common site, suggesting a possible role of inflammation in the attraction of circulating tumor cells. Oral metastasis has a serious prognosis. In this work, we describe the case of a 58-year-old man affected by renal cancer, who was brought to our attention for the appearance of a gingival swelling. Initially, the lesion was excised through a provisional clinical diagnosis of epulis. Subsequently, anatomopathological analysis showed a …

Osteonecrosis of the jaw in the era of targeted therapy and immunotherapy in oncology
2019
Osteonecrosis of the jaw (ONJ) is a well-known pathological condition in oncology derived from the use of bisphosphonates (BPs) and denosumab. Many molecular and immunological targets have been introduced for daily use in cancer treatment in recent years; consequently, new cases of ONJ have been reported in association with these drugs, especially if administered with BPs and denosumab. When the drugs are administered alone, ONJ is rarely seen. The objective of our study was to analyze the recent literature relative to the association of ONJ with these new drugs highlighting the pathogenic, clinical and therapeutic aspects. The close collaboration between maxillofacial surgeon, oncologist, …
Evaluación del grado de conversión de los receptores HER2, RE y RPg entre el cáncer de mama primario y sus respectivas metástasis
2017
Introducción: Tradicionalmente, las decisiones terapéuticas tanto del cáncer de mama precoz como de los estadios avanzados se han basado en los marcadores predictivos del tumor primario, tales como el receptor de estrógeno (RE), el receptor de progesterona (RPg) y el receptor 2 del factor de crecimiento epidérmico humano (HER2), asumiendo que éstos permanecían inmutables a nivel de la recaída metastásica. Objetivos: El objetivo general de esta tesis era investigar si el estado de los receptores HER2, RE y RPg realmente puede cambiar durante la progresión del cáncer de mama y profundizar en las causas y en el impacto clínico de dichos cambios. El objetivo principal era determinar la tasa de …
Deformable object segmentation in ultra-sound images
2013
Breast cancer is the second most common type of cancer being the leading cause of cancer death among females both in western and in economically developing countries. Medical imaging is key for early detection, diagnosis and treatment follow-up. Despite Digital Mammography (DM) remains the reference imaging modality, Ultra-Sound (US) imaging has proven to be a successful adjunct image modality for breast cancer screening, specially as a consequence of the discriminative capabilities that US offers for differentiating between solid lesions that are benign or malignant. Despite US usability,US suffers inconveniences due to its natural noise that compromises the diagnosis capabilities of radio…
Efectos adversos del tratamiento del cáncer oral
2008
- Francisco.Silvestre@uv.es En este estudio se hace una revisión de los efectos adversos más frecuentes por la cirugía de tumores de cabeza y cuello, la radioterapia y la quimioterapia, pues no es infrecuente que el odontólogo general encuentre en su consulta complicaciones como mucositis, xerostomía, necrosis óseas, alteraciones gustativas y otras lesiones que causarán molestias considerables al paciente, disminuyendo su calidad de vida. El papel del odontólogo en el tratamiento multidisciplinario constituye un pilar importante en la prevención, el tratamiento de dichas complicaciones y la disminución de sus secuelas. In this article a revision of most frequent adverse effects of head and …
Register and clinical follow-up of patients with Peutz-Jeghers syndrome in Valencia
2020
Introduction and aims: Peutz-Jeghers syndrome is a rare autosomal dominant inherited disease caused by a germline mutation of the STK11/LKB1 gene, located on chromosome 19p13.3. It is characterized by mucocutaneous hyperpigmentation, hamartomatous polyposis, and predisposition to cancer. The aim of the present study was to identify and register patients with Peutz-Jeghers syndrome, describe the disease, and estimate its prevalence in Valencia (Spain). Materials and methods: A print-out of the clinical histories from 10 hospitals was obtained utilizing the ICD-9 code 759.6 from the Minimum Basic Data Set of Hospital Admissions of the Spanish Ministry of Health and Consumer Affairs. Results: …
