Identification of clinical phenotypes and related survival in patients with large hccs
2021
Background. Hepatocellular carcinoma (HCC) factors, especially maximum tumor diameter (MTD), tumor multifocality, portal vein thrombosis (PVT), and serum alpha-fetoprotein (AFP), influence survival. Aim. To examine patterns of tumor factors in large HCC patients. Methods. A database of large HCC patients was examined. Results. A multiple Cox proportional hazard model on death identified low serum albumin levels and the presence of PVT and multifocality, with each having a hazard ratio ≥2.0. All combinations of these three parameters were examined in relation to survival. Using univariate Cox analysis, the combination of albumin >
Synchronous parenchymal renal tumors of different histology in the same kidney
2009
Background: Synchronous primary cortical tumors of different histology in the same kidney are rare. Preoperative awareness of this coexistence is important, since it can help in planning the surgical approach. Purpose: To describe the imaging findings observed in five patients with two parenchymal malignant tumors of different histology in the same kidney. Material and Methods: We reviewed the pathology reports of 381 patients operated for renal tumors from January 2000 to March 2007. The medical records of all patients with multiple, synchronous, primary lesions of different histology in the same kidney were reviewed with special attention to imaging findings and indications on the nature…
Prognostic role of tumour multifocality in renal cell carcinoma.
2012
Study Type - Therapy (multi-centre cohort) Level of Evidence3b What's known on the subject? and What does the study add? In RCC about 5% of the patients presented multifocal disease. Prevalence of tumour multifocality was associated with a higher percentage of symptomatic RCC, higher pathological TNM stages, higher tumour grade and higher prevalence of tumour necrosis. Although in univariable analysis multifocal tumours had lower probability of CSS, tumour multifocality did not retain an independent predictive role in multivariable analysis. Patient age at surgery, gender, mode of presentation, pathological N stage and presence of metastases were independent predictors of CSS in multivariab…
