BACKGROUND: Esophageal adenocarcinoma has one of the fastest rising incidence rates and one of the lowest survival rates of any cancer type in the Western world. However, in many countries, trends in esophageal cancer differ according to tumour morphology and anatomical location. In Canada, incidence and survival trends for esophageal cancer subtypes are poorly known.METHODS: Cancer incidence and mortality rates were obtained from the Canadian Cancer Registry, the National Cancer Incidence Reporting System and the Canadian Vital Statistics Death databases for the period from 1986 to 2006. Observed trends (annual per cent change) and five-year relative survival ratios were estimated separately for esophageal adenocarcinoma and squamous cell carcinoma, and according to location (upper, middle, or lower one-third of the esophagus). Incidence rates were projected up to the year 2026.RESULTS: Annual age-standardized incidence rates for esophageal cancer in 2004 to 2006 were 6.1 and 1.7 per 100,000 for males and females, respectively. Esophageal adenocarcinoma incidence rose by 3.9% (males) and 3.6% (females) per year for the period 1986 to 2006, with the steepest increase in the lower one-third of the esophagus (4.8% and 5.0% per year among males and females, respectively). In contrast, squamous cell carcinoma incidence declined by 3.3% (males) and 3.2% (females) per year since the early 1990s. The five-year relative survival ratio for esophageal cancer was 13% between 2004 and 2006, approximately a 3% increase since the period from 1992 to 1994. Projected incidence rates showed increases of 40% to 50% for esophageal adenocarcinoma and decreases of 30% for squamous cell carcinoma by 2026.DISCUSSION: Although esophageal cancer is rare in Canada, the incidence of esophageal adenocarcinoma has doubled in the past 20 years, which may reflect the increasing prevalence of obesity and gastroesophageal reflux disease. Declines in squamous cell carcinoma may be the result of the decreases in the prevalence of smoking in Canada. Given the low survival rates and the potential for further increases in incidence, esophageal adenocarcinoma warrants close attention.

Tumoricidal Activity

Cutaneous squamous cell carcinoma (cSCC) is the second most prevalent skin cancer globally. Because most cSCC cases are manageable by local excision/radiotherapy and hardly become life-threatening, they are often excluded from cancer registries in most countries. Compared with cutaneous melanoma that originates from the melanin-producing, neural crest-derived epidermal resident, keratinocyte (KC)-derived cancers are influenced by the immune system with regards to their pathogenetic behaviour. Congenital or acquired immunosurveillance impairments compromise tumoricidal activity and raises cSCC incidence rates. Intriguingly, expanded applications of programmed death-1 (PD-1) blockade therapies have revealed cSCC to be one of the most amenable targets, particularly when compared with the mucosal counterparts arisen in the esophagus or the cervix. The clinical observation reminds us that cutaneous tissue has a peculiarly high immunogenicity that can evoke tumoricidal recall responses topically. Here we attempt to redefine cSCC biology and review current knowledge about cSCC from multiple viewpoints that involve epidemiology, clinicopathology, molecular genetics, molecular immunology, and developmental biology. This synthesis not only underscores the primal importance of the immune system, rather than just a mere accumulation of ultraviolet-induced mutations but also reinforces the following hypothesis: PD-1 blockade effectively restores the immunity specially allowed to exist within the fully cornified squamous epithelium, that is, the epidermis.

220 Background: Although squamous metaplasia is commonly detected in pancreatic parenchyma, primary pancreatic squamous cell carcinoma (SCC) is a rare malignancy with unknown incidence and unclear prognosis. Methods: Using SEER-18 database primary code C25 in conjunction with histology codes for SCC (8052-8053, 8070-8078, 8083-8084) and for adenocarcinoma (AC) (8052-8053, 807-8078, 8083-8084), we identified cases diagnosed from 2000 to 2012. Age-adjusted incidence rates and trends over time were calculated. Patients with SCC were compared with AC by clinical features (TNM categories and histological differentiation), and 1-year and 2-year relative survival (RS) outcomes. Chi-square tests for categorical variables and t-tests for continuous variables were conducted. Kaplan-Meier method was used to estimate RS and Z-test was used to compare RS rates. SEERStat and GraphPad were used for analysis. Results: We identified 214 patients with microscopically confirmed SCC and 72,860 patients with AC. SCC constituted less than 1% of all cases of primary pancreatic cancer; however, age-adjusted incidence rates for this subtype tripled between 2000 and 2012. The annual percent increase of SCC incidence rate was 5.5%. Significant differences were observed by age, gender and race: older age groups, blacks and males had higher SCC incidence rates. Compared to AC, a greater proportion of patients with SCC had poorly differentiated histology (15.8% vs. 30.4%, p < 0.01). Similar to AC, the majority of patients with SCC had stage IV disease at diagnosis, 54.3% for AC vs. 56.4% SCC. The 1-year and 2-year relative survival rates were significantly lower in patients with SCC than AC. The 1-year relative survival rate was 15.8% (95%CI = 10.4-22.3) for SCC, compared with 24.7% (95%CI = 24.3-25.1) for AC, p < 0.001. Conclusions: Although primary squamous pancreatic carcinoma is a rare neoplasm, incidence rates for this subtype are markedly rising. Relative to adenocarcinoma, pancreatic squamous cell carcinoma is characterized by poorly differentiated histology and worse survival.
