background: sentinel  lymph  node  biopsy  has  shown  to  be  a  good  alternative procedure  for  axillary  lymph  node  dissection  and  to lead  to  lower  frequency  of morbidity, though this technique has its own side effects. it needs especial equipment and may not be available in some medical centers, especially in developing countries. this study aimed to identify a subgroup of patient...

Abstract Background Lymphadenectomy is central to tumor prognosis. 12 LNY during CRC resection a standard of good oncological resection, but 30–50 percent resections do not achieve this. LNR was suggested be more accurate predictive factor. Aim To examine the prognostic significance and on survival in patients with non-metastatic CRC. Method A retrospective study treated at DGH from January 201...

BACKGROUND AND OBJECTIVE Intraoral squamous cell carcinoma (OSCC) is one of the common tobacco related cancers affecting Indian population. These tumours are slow growing, endophytic and are mostly well differentiated. Cervical lymph node is the common site of metastasis of these tumours. In most of the patients cervical lymph node metastasis rather than the primary tumour, affects prognosis. H...

clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph node...

To pursue the process of lymph node metastasis, i.e, the preferential tumor growth in lymph node, we have established the non-metastatic M2B cell line which was derived from 3-methylcholanthrene-induced fibrosarcoma of C4W mouse and a metastatic cell line, M2BLN-M+ which was obtained from metastatic lymph nodes of irradiated C4W mouse which was subcutaneously implanted with cultured tumor cells...

The platelet-derived endothelial cell growth factor (PD-ECGF) level was significantly (P < 0.05) increased in 8 of 40 metastatic lymph node lesions of uterine cervical cancers. The prognosis of the eight patients with high PD-ECGF (>10,000 pg/mg protein) in metastatic lymph node lesions was extremely poor. On the other hand, the 24-month survival rate of the 32 patients with low PD-ECGF (<10,00...

The TNM pN stage based on the number of metastatic lymph nodes is an independent prognostic factor in gastric cancer. Many studies have highlighted the phenomenon of stage migration and problems in comparing groups of patients with different numbers of total lymph nodes harvested within TNM staging. The current version of UICC/AJCC and JGCA TNM classifications postulates a minimal number of 16 ...

Cervical lymph nodes are common sites of metastatic involvement in head and neck cancers. These lymph nodes are superficially located and palpation is a common practice for assessing nodal hardness and staging cancer which is, however, too subjective and with limited accuracy. In this study, the mechanical properties of pig lymph node tissues were investigated using ultrasound elastography and ...

BACKGROUND The aim of this study was to determine the prognostic value of metastatic lymph node ratio (n ratio). PATIENTS AND METHODS We retrospectively analyzed 202 patients who had undergone curative gastrectomy. The prognostic factors including UICC/AJCC TNM classification and n ratio were evaluated by univariate and multivariate analysis. RESULTS The n ratio was significantly higher in ...

Patients with carcinoma of the ampulla of Vater (CAV) have better outcomes among periampullary malignancies. However, little is known about the metastatic lymph node ratio (LNR) as a prognostic factor for resectable CAV. We retrospectively reviewed our CAV patients undergoing curative surgery and analyzed their prognostic factors.A total of 212 CAV patients who received radical surgery at Chang...
