Second primary cancers after an index head & neck cancer: subsite-specific trends in the era of hpv–associated oropharyngeal cancer

Source: American Society of Clinical Oncology Authors: Luc G.T. Morris, Andrew G. Sikora, Snehal G. Patel, Richard B. Hayes and Ian Ganly Abstract Purpose Patients with head and neck squamous cell carcinoma (HNSCC) are at elevated risk of second primary malignancies (SPM), most commonly of the head and neck (HN), lung, and esophagus. Our objectives were to identify HNSCC subsite-specific differences in SPM risk and distribution and to describe trends in risk over 3 decades, before and during the era of human papillomavirus (HPV) –associated oropharyngeal SCC. Methods Population-based cohort study of 75,087 patients with HNSCC in the Surveillance, Epidemiology, and End Results (SEER) program. SPM risk was quantified by using standardized incidence ratios (SIRs), excess absolute risk (EAR) per 10,000 person-years at risk (PYR), and number needed to observe. Trends in SPM risk were analyzed by using joinpoint log-linear regression. Results In patients with HNSCC, the SIR of second primary solid tumor was 2.2 (95% CI, 2.1 to 2.2), and the EAR was 167.7 cancers per 10,000 PYR. The risk of SPM was highest for hypopharyngeal SCC (SIR, 3.5; EAR, 307.1 per 10,000 PYR) and lowest for laryngeal SCC (SIR, 1.9; EAR, 147.8 per 10,000 PYR). The most common SPM site for patients with oral cavity and oropharynx SCC was HN; for patients with laryngeal and hypopharyngeal cancer, it was the lung. Since 1991, SPM risk has decreased significantly among patients with oropharyngeal SCC (annual percentage change in EAR, −4.6%; P = .03). Conclusion In patients with HNSCC, the risk and distribution of SPM differ [...]

Coffee and tea intake and risk of head and neck cancer: pooled analysis in the International Head and Neck Cancer Epidemiology Consortium

Source: CEBP Author: Mia Hashibe Abstract Background: Only a few studies have explored the relation between coffee and tea intake and head and neck cancers, with inconsistent results. Methods: We pooled individual-level data from nine case-control studies of head and neck cancers, including 5,139 cases and 9,028 controls. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI), adjusting for potential confounders. Results: Caffeinated coffee intake was inversely related with the risk of cancer of the oral cavity and pharynx: the ORs were 0.96 (95% CI, 0.94–0.98) for an increment of 1 cup per day and 0.61 (95% CI, 0.47–0.80) in drinkers of >4 cups per day versus nondrinkers. This latter estimate was consistent for different anatomic sites (OR, 0.46; 95% CI, 0.30–0.71 for oral cavity; OR, 0.58; 95% CI, 0.41–0.82 for oropharynx/hypopharynx; and OR, 0.61; 95% CI, 0.37–1.01 for oral cavity/pharynx not otherwise specified) and across strata of selected covariates. No association of caffeinated coffee drinking was found with laryngeal cancer (OR, 0.96; 95% CI, 0.64–1.45 in drinkers of >4 cups per day versus nondrinkers). Data on decaffeinated coffee were too sparse for detailed analysis, but indicated no increased risk. Tea intake was not associated with head and neck cancer risk (OR, 0.99; 95% CI, 0.89–1.11 for drinkers versus nondrinkers). Conclusions: This pooled analysis of case-control studies supports the hypothesis of an inverse association between caffeinated coffee drinking and risk of cancer of the oral cavity and pharynx. Impact: Given widespread use of coffee [...]

Research argues HPV vaccine should extend to boys

Source: RadioAustralia.net Author: Staff It is already available free to young girls in countries like Nauru, Vanuatu, Tuvalu and Cook Islands, but researchers are now saying the human papilloma virus, or HPV, vaccine Gardasil should also be offered to males. It follows new Australian research showing that the virus which causes cervical cancer in women is now a leading cause of oral cancer in men. It says 60 per cent of throat and tonsil cancers are caused by the virus. Presenter: Lindy Kerin Speaker: Barbara Rowe, associate professor in research with University of Sydney; Luke Connolly, director of Australian Centre for Economic Research; Dr Jonathan Clark, head and neck surgeon with Royal Prince Alfred and Liverpool Hospitals, New South Wales LINDY KERIN: For the past two years Australia has been rolling out the cervical cancer vaccine Gardasil to young women. It immunises them against the human papilloma virus, or HPV as it's known. Now there's growing evidence that the same virus is responsible for an increasing number of mouth and throat cancers in men. Barbara Rowe is an associate professor in research at the University of Sydney. BARBARA ROWE: We've tested just over 300 cancers of the oropharynx, and the oropharynx includes the tonsil and the base of tongue and part of the pharangyl wall. And we've tested those for the human papilloma virus type-16 and type-18, which the major cause of cervical cancer in women. And we found a sizeable proportion are associated with those types. In fact probably [...]
