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.

Esophageal cancer shows distinct geographic distributions, changing incidence rates, and primary risk factors when examined separately as squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma remains the dominant histologic type in many low- and middle-income countries and occurs frequently, while adenocarcinoma is classified as rare but predominates in Western countries. Tobacco and alcohol are the dominant risk factors for squamous cell carcinoma in Western countries, but not in high-incidence Asian populations, where hot beverages and specific nutritional deficiencies may be important. For adenocarcinoma, tobacco use is causal while alcoholic beverages are not. Rather, obesity and gastroesophageal reflux disease are the other dominant identified risk factors. Genetic predisposing factors and somatic mutations are also cell type specific. The differences in esophageal cancer incidence within and between countries, by sex and race, and in known risk factors suggest major strides in understanding the etiology of esophageal cancer is within reach.

Abstract Background Recent comprehensive mutation analyses have revealed a relatively small number of driver mutations in esophageal cancer, implicating a limited number of molecular targets, most of which are also implicated in squamous cell carcinoma. Methods In this study, we investigated genetic alterations in 44 esophageal squamous cell carcinomas (ESCC) and 8 adenocarcinomas (EAC) from Japanese patients as potential molecular targets, based on data from the Japanese version of The Genome Atlas (JCGA). Results Esophageal cancer was characterized by TP53 somatic mutations in ESCC (39/44, 88.6%) and EAC (5/8, 62.5%). In addition to TP53 mutations, somatic mutations in NFE2L2 (16/44, 36.4%), CDKN2A (7/44, 15.9%), and KMT2D (7/44, 15.9%) were more frequently detected in ESCC than in EAC. WRN-truncated type mutations that lead to genomic instability correlate with EAC, but not ESCC. ESCC samples were enriched in ALDH2-associated mutational signature 16 as well as the APOBEC signature. Patients with FAT2 mutations had significantly poorer overall survival compared with those with wild-type status at FAT2 (p < 0.05). Patients with EP300 or PTPRD mutations also had poor progression-free survival compared with respective wild-types (p < 0.05 or p < 0.001). Conclusions These findings may facilitate future precision medicine approaches based on genomic profiling in ESCC and EAC.

Abstract Background We sometimes experience cases of cervical esophageal cancer which requires laryngectomy due to spread of cancer to larynx. We report a case of esophageal cancer resection with preservation of larynx using intraoperative endoscopic submucosal dissection. Methods The patient was a 59-year-old woman who had dysphagia. She had received total gastrectomy with Roux-en-Y reconstruction for gastric cancer in 2001, chemoradiation (61.2Gy) for esophageal cancer in 2008. Argon plasma coagulation (APC) was performed for the carcinoma in situ of cervical esophagus in 2016. This time superficial 0-IIc tumor was observed at the same site of the scar of APC, and a biopsy revealed squamous cell carcinoma. An endoscopic findings revealed two 0-IIc lesions at distance of 18–22 cm, and 32–34 cm from the incisors, and biopsy resulted in a diagnosis of squamous cell carcinoma. Since tumor was close to the esophageal orifice, the tumor invasion to the larynx was suspected. On the other hand, there were no obvious findings of the submucosal layer invasion, and the both tumor were thought to be limited to the epithelium or lamina propria mucosae (EP/LPM). We performed mediastinoscopic and thoracoscopic transhiatal esophagectomy, subcutaneous ileocolic reconstruction. Results After confirming the tumor invasion to the esophageal orifice by chromoendoscopy with 1% Lugol's iodine solution, we dissected the whole circumference of esophagus in submucosal layer just above the tumor by ESD, put an incision outside of esophageal wall, and resected the esophagus. We preserved short length of muscle layer and performed reconstruction with hypopharynx-ileum anastomosis. Pathological examination revealed squamous cell carcinoma, pT1a-EP, ly0, v0, pPM0, pDM0, pIM0, and curative resection was performed. The postoperative course was uneventful. Conclusion There were no reports of successful larynx-preserving surgery for cervical esophageal cancer using intraoperative ESD. When the tumor was limited in the mucosa, esophagectomy with intraoperative ESD may enable larynx preservation even if the tumor invaded to the esophageal orifice.

The incidence and histological type of esophageal cancer are highly variable depending on geographic location and race/ethnicity. Here we want to determine if racial difference exists in the molecular features of esophageal cancer. We firstly confirmed that the incidence rate of esophagus adenocarcinoma (EA) was higher in Whites than in Asians and Blacks, while the incidence of esophageal squamous cell carcinoma (ESCC) was highest in Asians. Then we compared the genome-wide somatic mutations, methylation, and gene expression to identify differential genes by race. The mutation frequencies of some genes in the same pathway showed opposite difference between Asian and White patients, but their functional effects to the pathway may be consistent. The global patterns of methylation and expression were similar, which reflected the common characteristics of ESCC tumors from different populations. A small number of genes had significant differences between Asians and Whites. More interesting, the racial differences of COL11A1 were consistent across multiple molecular levels, with higher mutation frequency, higher methylation, and lower expression in White patients. This indicated that COL11A1 might play important roles in ESCC, especially in White population. Additional studies are needed to further explore their functions in esophageal cancer.

Objective: Early detection of hypopharyngeal squamous cell carcinoma (SCC) is important for both an improved prognosis and less-invasive treatment. We retrospectively analyzed the detection rates of early hypopharyngeal SCCs according to the evaluation methods and the clinical management of early hypopharyngeal SCCs. Methods: Sixty-eight patients with early hypopharyngeal SCC who were diagnosed were reviewed. Results: The number of early hypopharyngeal cancer patients with asymptomatic or synchronous or metachronous esophageal cancer examined by upper gastrointestinal endoscopy with narrow-band imaging (NBI) was significantly higher than those examined by laryngopharyngeal endoscopy with NBI. The 3-year disease-specific survival rates according to T classification were as follows: Tis, 100%; T1, 100%; T2, 79.8%; and overall, 91.2%, respectively. Conclusions: Early-stage hypopharyngeal SCC can be cured by minimally invasive transoral surgery or radiotherapy. Observation of the pharynx using NBI in patients with a history of head and neck cancer, esophageal cancer, gastric cancer, or pharyngeal discomfort is very important, and routinely examining the pharynx with NBI, even in patients undergoing endoscopy for screening purposes, is recommended.
