Endoscopic surgery is increasingly used for early gastric cancer (EGC) treatment worldwide, and lymph node metastasis remains the most important risk factor for endoscopic surgery in EGC patients. Olfactomedin 4 (OLFM4) is mainly expressed in the digestive system and upregulated in several types of tumors. However, the role of OLFM4 in EGC has not been explored. We evaluated OLFM4 expression by...

BACKGROUND The diagnostic power of CT or MRI on the lymph node status was limited. Supplement measurements were needed to assist the diagnosis of lymph node metastasis. The SCCa was reported to be close related to lymph node status. But currently the clinical value of serum SCCa measurement in lymph node status has not been clearly defined. This meta-analysis was to investigate this topic on a ...

In order to predict related risk factors for lymph node metastasis (LNM) in patients with superficial esophageal carcinoma (SEC) and provide reference for endoscopic minimally invasive treatment, we included a total of 93 patients with superficial esophageal carcinoma who have underwent esophagectomy and lymph node dissection from 2010 to 2015. The depth of invasion was remeasured and classifie...

Heme oxygenase-1 (HO-1) is known as a stress-inducible protein. The present study was designed to investigate the relationship between HO-1 expression levels and clinical features of tongue cancer by using HO-1 responsiveness to stress as a clinical indicator. One-hundred and twelve biopsy samples from tongue squamous cell carcinomas were analyzed semiquantitatively by immunohistochemistry. Cor...

A total of 1,845 cases of gastric cancer have been resected in our hospital during the past 18 years. Of these, 764 cases (41.5%) were early gastric cancer. The rate of lymph node metastasis was 2% in early mucosal cancer and 19.4% in early submucosal cancer (p < 0.001). In the cases of early mucosal cancer, the rate of lymph node metastasis was 0.9% for the elevated type and 2.4% for the depre...

OBJECTIVES To assess the association between muscle invasion by oral squamous cell carcinoma of the posterior mandibular alveolar ridge and cervical lymph node metastasis on the basis of preoperative magnetic resonance imaging (MRI). MATERIALS AND METHODS Twenty-six patients with oral squamous cell carcinoma of the posterior mandibular alveolar ridge were evaluated by MRI. The associations be...

  Adenosquamous carcinomas of stomach are rare entities comprising 0.5% of stomach carcinomas. Here, we report a case of a 50-year-old female, who presented with weakness, pallor, and symptoms of gastric outlet obstruction. A partial gastrectomy was done and histology showed evidence of adenosquamous carcinoma of the antrum with metastasis to the perigastric lymph nodes. The patient condition ...

A prospective study was performed to assess the efficacy of elective neck irradiation (ENI) on the ipsilateral side in patients with early tongue cancer among a high-risk group with late cervical lymph node metastasis. Patients in the high-risk group had T2-tumors, excluding superficials or T1-tumors > or =19 mm in maximal diameter with invasion or ulcer. Between February 1989 and October 1997,...

OBJECTIVE The aim of this study was to evaluate the impact of para-aortic lymphadenectomy up to the renal vessels on the accurate staging in ovarian cancer patients presumed preoperatively to be confined to the ovary. METHODS We retrospectively analyzed data on 124 patients with primary epithelial ovarian cancer who were preoperatively thought to have tumor confined to the ovary and underwent...

Systemic lymph node metastasis is a rare event in malignant mesothelioma. It is even more exceptional when systemic lymph node metastasis is the initial clinical presentation. Review of literature discloses only four cases in which metastatic lymphadenopathy was the only symptom of malignant mesothelioma. We, herewith, report three cases where the initial diagnosis of malignant mesothelioma was...
