A retrospective study of 25 patients treated for primary gastric lymphoma was made to investigate a number of problems related to treatments and report the factors influencing prognosis. In the 5-year-survival rate according to Working Formulation classification, either survival rate of low-grade type or intermediate-grade type was higher than that of high-grade type. Both the 5-year-survival r...

INTRODUCTION The majority of ovarian cancer recurrences are in the abdomen. However, some cases relapse as isolated lymph node metastases, mostly in pelvic or para-aortic nodes. Peripheral isolated lymph node metastasis is rare. CASE PRESENTATION A 69-year-old Japanese woman had recurrent ovarian cancer presenting with isolated right supraclavicular lymph node metastasis. After surgical resec...

PURPOSE To analyze the incidence and patterns of calcification of papillary thyroid microcarcinoma (PTMC) on neck ultrasonography (NUS) and assess the clinical implications of calcification, especially for neck node metastasis. METHODS The clinical data of 379 patients with PTMC who underwent thyroidectomy between January and December 2011 were retrospectively analyzed. PTMC lesions were clas...

Purpose: Submucosal invasive colorectal carcinoma (SICC) exhibits lymph node metastasis in about 10% of patients. Therefore, endoscopic resection is insufficient for cases of SICC at risk of lymph node metastasis, and surgical resection accompanied with lymph node dissection is necessary. However, because additional intestinal resection is unnecessary for cases without lymph node metastasis, mo...

The aim of the present study was to elucidate the associations between the expression of the vascular endothelial growth factor-C (VEGF-C)/VEGF receptor-3 (VEGFR-3) axis and lymphangiogenesis, regional lymph node metastasis and clinicopathological factors in oral tongue squamous cell carcinoma (OTSCC) using immunohistochemistry. The expression of VEGF-C, VEGFR-3 and podoplanin was immunohistoch...

Ductal breast cancer is a clinically heterogeneous disease; we investigate the correlation between tumor size, comedo necrosis, number of cell mitoses and axillary lymph node metastasis in ductal breast cancer. In this study, 104 ductal breast cancer specimens were collected and divided into 3 groups: T1 group (tumor size ≤ 2 cm), T2 group (2 < tumor size ≤ 5 cm) and T3 group (tumor size > 5.0 ...

BACKGROUND Lateral cervical lymph node metastasis without central lymph node (CLN) metastasis is not infrequent in papillary thyroid cancer (PTC). This study was designed to investigate the frequency and pattern of skip metastasis in PTC. METHODS We reviewed 131 patients who underwent total thyroidectomy with CLN dissection and selective lymph node dissection. Tumor location was classified in...

Surgical staging, including lymph node sampling, for endometrial cancer was adopted by the International Federation of Gynecology and Obstetrics (FIGO) in 1988 based on reports demonstrating diagnostic and therapeutic advantages. This review focuses on the incidence of lymph node metastasis, risk factors for lymph node involvement, the effect of lymph node metastasis on prognosis, the therapeut...

OBJECTIVES The objectives of this study were to evaluate the formation of lymphvascular niches in lymph nodes of patients with oral squamous cell carcinoma (OSCC), and investigate the roles of lymphangiogenic and angiogenic factors, such as vascular endothelial growth factor (VEGF)-A, VEGF-C, and VEGF-D, expressed in the primary tumors. MATERIALS AND METHODS Forty-four patients with previousl...
