It’s perplexing to many of us as to why some infants present with mild inconsequential expiratory stridor that gets better over time, others have swallowing difficulty and are considered to have moderate disease, and then there are those that are severe and have cardiopulmonary complications like hypoxia, chronic cyanosis, and significant stridor. – -Dana M.

The SEER Data Set shows an improvement overall for cancer survival in the United States across those years, despite the concurrent decline in survival for laryngeal cancer. Dr. Hoffman and his colleagues reviewed the NCDB to confirm these findings and to examine a variety of hypotheses as to why the decrease in survival has occurred, including the possibility that the decrease was actually an artifact of the database.
Our review of the NCDB identified over 158,000 cases accrued over a 15-year period, and this review did support the SEER data findings identifying a decline in survival for laryngeal cancer from the mid 80s to the mid 90s, Dr. Hoffman said. This decline in survival more markedly affected supraglottic cancers but also affected glottic cancers as well.
