Immunoexpression of human leukocyte antigen-DR in actinic cheilitis and lower lip squamous cell carcinoma

Abstract The aim of this study was to evaluate the immunoexpression of human leukocyte antigen-DR (HLA-DR) in actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), and to correlate the findings with clinical (tumor size/extent, regional lymph node metastasis, and clinical stage) and histo...

Total omentectomy in gastric cancer surgery: is it always necessary?

ABCD (São Paulo, Impr.); 32 (1), 2019
ABSTRACT Background: Traditionally, total omentectomy is performed along with gastric resection and extended lymphadenectomy in gastric cancer (GC) surgery. However, solid evidences regarding its oncologic benefit is still scarce. Aim: To evaluate the incidence of metastatic omental lymph nodes (LN) ...

Malignant transformation of abdominal wall endometriosis to clear cell carcinoma: case report

Säo Paulo med. j; 136 (6), 2018
ABSTRACT BACKGROUND: Malignant transformation of endometriosis in the abdominal wall is a rare and still poorly understood event. Less than 30 cases have been reported in the worldwide literature.

Comparative study of computed tomography (CT) and pathological diagnosis toward mediastinal lymph node metastasis in esophageal carcinoma

Summary Objective: To investigate the diagnostic criteria of mediastinal lymph node metastasis (MLNM) in esophageal carcinoma (EC) by comparing the lymph node sizes measured by computed tomography (CT) and obtained by postoperative pathological examination. Method: A total of 305 EC patients were selec...

The role of serum ck-18, mmp-9 and tipm-1 levels in predicting r0 resection in patients with gastric cancer

ABCD (São Paulo, Impr.); 31 (4), 2018
ABSTRACT Background: Gastric cancer is the 3rd most common cause of death in men and the 5th common in women worldwide. Today, surgery is the only curative therapy. Currently available advanced imaging modalities can predict R0 resection in most patients, but it can only be detected with certainty in t...

Clinical impact of thyroglobulin (Tg) and Tg autoantibody (TgAb) measurements in needle washouts of neck lymph node biopsies in the management of patients with papillary thyroid carcinoma

ABSTRACT Objectives The presence of thyroglobulin (Tg) in needle washouts of fine needle aspiration biopsy (Tg-FNAB) in neck lymph nodes (LNs) suspected of metastasis has become a cornerstone in the follow-up of patients with papillary thyroid carcinoma (PTC). However, there are limited data regarding ...

Upregulation of lncRNA BANCR associated with the lymph node metastasis and poor prognosis in colorectal cancer

Biol. Res; 50 (), 2017
BACKGROUND: Growing evidence has supported that long non-coding RNAs (lncRNAs) could play vital roles in the development, progression, and prognosis of colorectal cancer (CRC). However, little is known about the clinical significance of BRAF-activated non-coding RNA (BANCR) in CRC. The aim of this study ...

Oral cavity squamous cell carcinoma: factors related to occult lymph node metastasis

INTRODUCTION: Elective neck dissection is recommended in cases of oral cavity squamous cell carcinoma without lymph node metastasis because of the risk of occult metastasis. OBJECTIVE: The present study aimed to evaluate predictive factors for occult lymph node metastasis in patients with oral cavity squ...
