Researchers looked at about 150 people who had surgery for early stage squamous cell carcinoma of the tongue and found that obese patients had a five-fold increased risk of death. Three years after surgery, 87 percent of normal-weight patients were alive, compared with 68 percent of obese patients, according to the findings, which were published recently in the journal Cancer. The study is the first to link obesity and increased risk of death in patients with any type of head or neck cancer, the researchers said. They said previous studies have found an association between obesity and worse outcomes among patients with several common cancers, including breast and colon cancers. "The role of obesity across several common cancers is a focus of increased attention," study senior author Dr. Clifford Hudis, chief of breast cancer medicine at the Memorial Sloan Kettering Cancer Center in New York City, said in a center news release. Hudis is also president of the American Society of Clinical Oncology. Because the study was so specific in terms of the cancer's location in the body and disease stage, it helped clarify the effect of obesity, another researcher said. "Most prior research investigating the interaction between [obesity] and head and neck cancers included multiple tumor sites and disease [...]
