We observed overall 30.8% positive SNs in 13 consecutive patients operated for high-risk nonmelanoma skin cancer between 2002 and 2011 in our institution. (hindawi.com)
These high rates support recommendation to implement SLNB for nonmelanoma skin cancer especially for SCC patients. (hindawi.com)
However, because of its low morbidity when compared to empiric elective lymph node dissection or radiation therapy of lymphatic basins, SLNB has allowed sparing a lot of morbidity and could therefore be used in nonmelanoma skin cancer patients, even though a significant impact on survival has not been demonstrated. (hindawi.com)
Because of the low incidence of nonmelanoma skin cancer with potential metastatic spread and the lack of large clinical trials, the use of SLNB in these cases is not well established, and no guidelines are currently available. (hindawi.com)
In this context, the role of SLNB in nonmelanoma skin cancer should be accepted as a standard staging procedure assuming that N status is a strong predictive factor for survival. (hindawi.com)
Over a 10-year period from January 2002 to December 2011, a total number of thirteen patients underwent a SLNB for nonmelanoma skin cancer at the University Hospital of Lausanne, Switzerland. (hindawi.com)
The aim of our present study was to analyze the rate of positive SNs and reliability regarding false negative rate during followup in nonmelanoma skin cancer patients in our series and compare our data with a review of the current literature. (hindawi.com)

Inflammatory responses resulting from workplace exposures are usually observed in specific target organs, such as the lung, skin and liver and, if persistent, may progress to fibrosis, granulomatous disease or even cancer. (cdc.gov)
These changes have been predicted by cancer epidemiologists for many years, but even they are surprised by the speed at which these changes are occurring, e.g., the emergence of cancer of the breast, colon and prostate in several countries in which these neoplasms were hardly known only 20 to 30 years ago.

[ 1 ] The incidence of salivary gland neoplasms as a whole is approximately 5.5 cases per 100,000 individuals in the United States, with malignant neoplasms accounting for 0.9 cases per 100,000. (medscape.com)

As malignant cells have a tendency to round up in body fluids these non-epithelial neoplasms can therefore mimic reactive mesothelial cells and metastatic adenocarcinoma. (cytojournal.com)
