A team of researchers from UNC Lineberger Comprehensive Cancer Center analyzed data from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) database and found that, between 1975 and 2007, the overall incidence for all ages, genders, and races of the disease was decreasing.
However, the incidence of oral tongue squamous cell carcinoma rose 28 percent among individuals ages 18 to 44. Specifically, among white individuals ages 18 to 44 the incidence increased 67 percent. The increasing incidence was most dramatic for white females ages 18 to 44. They had a percentage change of 111 percent. Interestingly, the incidence decreased for African American and other racial groups.
Historically, oral tongue cancer has been strongly associated with heavy tobacco and alcohol use. Other epidemiological studies have related the decreasing incidence of oral tongue cancer in the United States to the decreased use of tobacco products. Though the UNC research team verified the known decreasing incidence of oral tongue cancer, they were surprised to observe an increasing incidence in young white individuals, specifically young white females.
"Lately we have been seeing more oral tongue cancer in young white women in our clinic. So we looked at the literature, which reported an increase in oral tongue squamous cell carcinoma in young white individuals but couldn't find any information about gender-specific incidence rates, so we decided we should take a look at the SEER data," said Bhisham Chera, MD, lead author on the study and assistant professor in the Department of Radiation Oncology.
Over the past decade an association between the human papilloma virus with squamous cell carcinoma of the tonsil and tongue has been observed. Patients with human papilloma virus associated oral squamous cell carcinoma are typically male, white, non-smokers, non-drinkers, younger in age and have higher socioeconomic status. The researchers at UNC have preliminarily tested the cancers of the oral tongue of their young white female patients and have not found them to be associated with the virus. Other institutions have also noted the absence of the virus in young females with oral tongue cancer. The UNC researchers have also anecdotally observed that these young white female patients are typically non-smokers and non-drinkers.
"Our findings suggest that the epidemiology of this cancer in young white females may be unique and that the causative factors may be things other than tobacco and alcohol abuse. Based on our observations and the published data, it appears that these cases may not be associated with the human papilloma virus. We are actively researching other causes of this cancer in this patient population." he added.
Though the increasing rate of oral tongue cancer in young white females is alarming oral tongue cancer is a rare cancer, relative to breast, lung, prostate, and colorectal cancer. "Primary care physicians and dentist should be aware of this increasing incidence and screen patients appropriately," states Dr. Chera. Oral tongue cancer is typically treated with surgery first followed by radiation and, in some cases, chemotherapy.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
