Incidence, timing, presentation, treatment, and outcomes of second primary head and neck squamous cell carcinoma after oral cancer

LoweAbstractAfter their initial presentation of oral squamous cell carcinoma (SCC), patients have a lifelong risk of developing another new SCC of the head and neck. The aim of this study was to establish second primary rates, baseline characteristics (site, clinical or pathological stage, and smoking and alcohol history), timing, presentation, treatment, and outcomes. From the regional unit we analysed records of patients treated with curative intent for their first oral cancer between 2002 and 2007 inclusive. All patients had had at least 10 years of follow up either to death or the end of 2017. A total of 347 patients had been treated with curative intent, and of them, 29 had a second primary at a median (IQR) of 52 (30-79) months after the index operation. The incidence of developing a second primary tumour within two years was 1.7% (95% CI: 0.7% to 3.7%), within five years was 4.9% (95% CI: 2.9% to 7.7%), and within 10 years was 7.8% (95% CI: 5.1% to 11.1%). Early stage of first cancer was the only significant factor (p = 0.001) for development of a second primary within 10 years, reflecting survivorship. Most second primaries (21 patients) were staged as early, and by visual inspection. Most (n = 20) were within the oral cavity, one of which overlapped the oropharynx; eight others were in the orop...

Authors: Misawa K, Imai A, Mochizuki D, Mima M, Endo S, Misawa Y, Kanazawa T, Mineta H Abstract The aim of this study was to clarify the epigenetic regulation of ten eleven translocation protein (TET) family genes, which can provide insights into the mechanisms of tumorigenesis and the risk of disease recurrence in head and neck squamous cell carcinoma (HNSCC). We generated methylation profiles of TET1, TET2 and TET3 genes in tumor samples obtained from 233 patients with HNSCC; these included 57 hypopharynx, 44 larynx, 69 oral cavity, and 63 oropharynx tumor samples. The mRNA expression and promoter DNA methylation...

Alcohol consumption is an established risk factor, and also a potential prognostic factor, for squamous cell carcinoma of the head and neck (HNSCC). However, little is known about whether the prognostic impact of alcohol consumption differs by treatment method. We evaluated the association between alcohol drinking and survival by treatment method to the primary site in 427 patients with HNSCC treated between 2005 and 2013 at Aichi Cancer Center Central Hospital (Nagoya, Japan). The impact of alcohol on prognosis was measured by multivariable Cox regression analysis adjusted for established prognostic factors. Among all HNS...

Squamous cell carcinoma arises from multiple anatomic subsites in the head and neck region. The risk factors for development of cancers of the oral cavity, oropharynx, hypopharynx, and larynx include tobacco exposure and alcohol dependence, and infection with oncogenic viruses is associated with cancers developing in the nasopharynx, palatine, and lingual tonsils of the oropharynx. The incidence of human papillomavirus–associated oropharyngeal cancer is increasing in developed countries, and by 2020, the annual incidence could surpass that of cervical cancer.

Conclusion In view of the significant association of HPV with HNSCC, studies with accurate subsite classification and more sensitive detection methods are necessary. Accurate data from this geographical region are essential to inform public health policies and treatment decisions, especially as studies from Europe and North America reveal HPV-driven cancers to be less aggressive, permitting treatment de-intensification.

For years studies have attempted to come up with measures and markers that predict and are linked to cancer survival. Alterations in a subgroup of genes, tumor suppressor genes (TSG), have recently emerged as important in linkage to cancer survival, particularly the silencing that can occur by somatic mutations and promoter DNA methylation. However, the link between TSG silencing and cancer survival is not well understood. If we can understand how TSG silencing is molecularly linked to cancer survival we can improve clinical management and pave the wave for personalized treatment solutions. Head and neck squamous cell carc...

Conclusion: This study is the first to demonstrate that alpha HPV16 detection precedes the incidence of oropharyngeal cancers. Risks identified with other HPV types from gamma11 and 12 species as well as beta HPV5, previously associated with skin cancer, suggests a broader role for HPVs in HNSCC etiology. Readily-collected oral wash samples provide a strong prospective marker for oropharyngeal cancer and, with the incorporation of other HPV types, may indicate risk for a broader spectrum of HNSCC.Citation Format: Ilir Agalliu, Zigui Chen, Tao Wang, Rebecca Ludvigsen, Lauren Teras, Aimee R.
