Background: Information on hook-wire guided (HWG) surgery for non-palpable thyroid carcinoma (TC), locoregional-recurrent disease (LRRD) is scarce. We analyze the results of HWG resection compared with the traditional procedure.
Methods: Cohort study performed between January 2016 and December 2020.
Background: The expression of liver kinase B1 (LKB-1) has been associated with prognosis in squamous cell carcinoma of the oral cavity (SCCOC). This study aimed to define the prognostic role of LKB-1 expression for patients with SCCOC and the suitability of its integration into a multivariate prognostic model.
Methods: A retrospective cohort study of patients with SCCOC was conducted in a cancer center.
Introduction: In patients with unresectable Differentiated thyroid cancer (DTC), the use of external beam radiation therapy (EBRT), leads mostly to palliation. Our aim is to define the role of upfront EBRT, followed or not by salvage surgery, on Progression-free survival (PFS) or Overall survival (OS) in patients with DTC.
Methods: This is a cohort study of patients with initially unresectable DTC who received EBRT.
Prognostic Impact of Direct I Therapy After Detection of Biochemical Recurrence in Intermediate or High-Risk Differentiated Thyroid Cancer: A Retrospective Cohort Study.
Front Endocrinol (Lausanne)
October 2019
Patients treated for intermediate- or high-risk differentiated thyroid carcinoma (DTC) and Thyroglobulin (TG) elevation during follow-up, require a diagnostic whole-body scan (DWBS) and if positive, I treatment. This approach can lead to a delay in treatment and increased costs. The purpose of this study is to compare the oncologic outcomes associated to administration of direct therapy with I at first biochemical recurrence.
View Article and Find Full Text PDFBackground: Prognostic factors in oral cavity and oropharyngeal squamous cell carcinoma (SCC) are debated. The purpose of this study was to investigate the association of prognostic factors with oncologic outcomes.
Methods: Patients with oral cavity and oropharyngeal SCC treated from 1997 to 2012 were included in this retrospective cohort study.
Background: This study was performed to define prognostic factors and management of minor salivary gland carcinoma of the oral cavity and oropharynx .
Methods: Retrospective analyses of patients with salivary gland carcinoma of the oral cavity or oropharynx, treated in 1989 to 2006. Statistics included univariate analyses to identify prognostic factors associated with disease-free survival (DFS) and disease-specific survival.
The aims of this study were to identify the effect of clofibrate administration in the development of high blood pressure secondary to aortic coarctation (AoCo) and to assess its effect on vascular reactivity. Three experimental groups of rats were used: sham-operated, aortic coarctated vehicle-treated (AoCo-V), and aortic coarctated clofibrate-treated (AoCo-C100). The rats were treated for seven days.
View Article and Find Full Text PDFBackground: The use of fine needle aspiration biopsy (FNAB) for diagnosis of parotid gland masses (PGM) is questioned, because of low sensitivity and the generalized belief requiring surgery for most parotid masses. Information available is retrospective. Our objective was to evaluate the diagnostic accuracy of FNAB for diagnosis of patients with PGM.
View Article and Find Full Text PDFBackground: Parotid gland carcinoma is an infrequent tumor, and series that report on these neoplasms are relatively scarce in the literature. The objective of the current study was to identify prognostic factors in patients with parotid gland carcinoma and to develop a method for defining the probability of recurrence.
Methods: Patients with parotid gland carcinoma who were treated at the authors' institution from January 1981 through December 2004 and who completed treatment constituted the study group.
