Retrospective study: squamous cell carcinoma in the hypopharynx and supraglottis in a period from 2002 to 2016

Introduction:

The following study was conducted to investigate the behavior of lymph nodes metastases of hypoharyngeal and supraglottic cancer. The presence of metastatic lymph nodes represent one oft he most important prognostic factor in terms of survival rates. There is still no sufficient data about the extension of the neck dissection yet.

Material and methods:

In the period of 15 years we collected data from a total number of 148 patients who suffered from hypopharyngeal and supralaryngeal cancer. All of them underwent surgical tumor resection and bilateral neck dissection. The data on the histology of the neck dissection and the exact localisation of the primary tumor were evaluated retrospectively. The analyse of neck dissection was determined by the number of lymph node metastases and the presence of an extracapsular growth.

Results:

There was a significant difference in the metastatic behavior between the pT1 and pT2-pT4 stages of squamous cell carcinoma. In only one of twenty diagnosed supralaryngeal carcinoma we found bilateral lymph node metastases. In hypopharyngeal carcinoma there was a clear discrepancy in the metastastic behavior with regard to the localization of primary tumor. An affected aryepiglottic fold was highly associated with the presence of bilaterale lymph node metastases compared to others sites of hypopharyngeal cancer.

Conclusions:

A clear statement on the metastasis behavior can not be made on the basis of our data for the T-stage of hypopharyngeal carcinoma
