lymph node dissection is of prime importance for accurate staging of colorectal carcinomas. since a great number of small lymph nodes are missed in the traditional method, several fat clearing solutions have been introduced for easier detection of smaller lymph nodes. in this study we evaluated the efficacy of a new fat clearing solution so-called lymph node revealing solution (lnrs) in colecto...

Breast cancer is one of the most common malignancies in the world. The most important prognostic factor in this cancer is the stage of the tumor. Detection of lymph nodes with or without malignancy is essential for determining the stage of the tumor and setting a therapeutic plan. There are different methods for isolating lymph nodes in surgical specimens of breast cancer in the pathology ...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...

background: in this study we evaluated the prognostic impact of metastatic lymph node ratio (mlr) in patients with gastric cancer undergoing curative surgical resection. methods: a total of 121 patients with gastric adenocarcinoma undergoing curative r0 surgical resection in our institutions between 2003 and 2010 were included in this study.  mlr was classified into 3 groups as follows: mlr0; 0...

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...

The Royal College of Pathologists (RCPath) and College of American Pathologists recommend that at least 12 lymph nodes should be harvested for adequate staging of colorectal carcinoma. Just one nodal tumour deposit upstages the malignancy from pN0 to pN1. This is critically important as node-positive patients (pN1) are considered for adjuvant chemotherapy whereas node-negative patients (pN0) ma...

nineteen lymph node biopsies, 3 curetting, 15 blood samples obtained from patients with lymphadenitis and high titers of toxoplasma antibodies, and 27 tonsillar tissues removed from patients because of chronic tonsillitis were inoculated intraperitoneally into mice for isolation of toxoplasma gondii. toxoplasms were isolated from 5 lymph node biopsies, one curettage material, 2 tonsillar tissue...
