OBJECTIVE To identify predictors of levels II and Vb involvement in papillary thyroid cancer (PTC) with lateral neck metastasis. DESIGN Large case series. SETTING High-volume tertiary care hospital. PATIENTS Consecutive sample of 185 patients who underwent 248 selective neck dissections of at least levels II to V for pathologically proven PTC. MAIN OUTCOME MEASURES Significant independe...
INTRODUCTION It has been suggested that a complete staging may be safely omitted in endometrial carcinoma patients at low risk for lymph node metastasis. The purposes of our study were to explore the prognostic significance of pathologic factors for pelvic and paraaortic nodal spread and to validate the Mayo algorithm in order to identify patients in whom lymphadenectomy may be avoided. MATER...
BACKGROUND Scalp/neck melanomas have a poor prognosis, possibly because of a rich vascular supply that prompts tumor cells' dissemination. METHODS We compared the accuracy of immunohistochemical (IHC) staining with morphology for the identification of lymphovascular invasion in 156 scalp/neck melanomas. We then analyzed the association of vessel invasion and density with pathological features...
BACKGROUND Current risk factors for lymph node metastasis in early gastric cancer have been primarily determined in Asian countries; however their applicability to Western nations is under discussion. The aim of our study was to identify risk factors associated with lymph node metastasis in Western cohort patients from the Eastern European country - Lithuania. METHODS A total of 218 patients ...
Background & Objective: Lymphovascular tumoral invasion is a typical histopathological feature of gastric carcinomas and supports the recognition high-risk patients for recurrence. We aimed to study CD31 expression in diverse subtypes show its association with histopathologic findings carcinoma assess prognosis.Methods: This cross-sectional was conducted on 40 established adenocarcinoma from ra...
Background and purpose: Regional lymph node involvement is one of the main prognostic factors for breast cancer. Intraoperative assessment of sentinel lymph node biopsy (SLNB) by frozen section (FS) allows necessary axillary lymph node dissection (ALND) at the same time. But, false negative results are the main problems of the FS. The aim of this study was to investigate the relationship betwee...
Introduction: Triple-negative breast cancer (TNBC) is a type of breast cancer that is negative for estrogen receptor, progesterone receptor, and HER2. This study aimed to evaluate the clinical outcomes and short-term prognosis of this type of cancer compared with other subtypes of breast cancer. Methods: A cross-sectional study was conducted on 108 women with invasive breast cancer. The patie...
BACKGROUND Selected cases of early gastric cancer (EGC) can be successfully treated by endoscopic therapy if the risk of concurrent lymph node metastases (LNM) is negligible. Criteria for endoscopic resection based on risk factor analyses for LNM have been established mainly in Asia. However, it is not clear to what extent these recommendations can be transferred to Western collectives. The aim...
