INTRODUCTION: Esophageal cancer is one of the most common cancers in the world affecting males more often than females and with a poor prognosis. The aim of our work was to describe the epidemiology of patients followed for esophageal cancer at the Joliot-Curie Institute in 2018. MATERIALS AND METHODS: This is a descriptive retrospective study including all patients followed at the institute from January 1, 2018 to December 31, 2018 for esophageal cancer with histological evidence. RESULTS: We collected 93 patients referred to the institute for the management of esophageal cancer, 46 women (49.5%) and 47 men (50.5%). The mean age was 49 years with a median age of 50 and extremes of 22 and 84 years. The notion of smoking was found in 24 patients (25.8%) exclusively men (51%), associated in six cases with a notion of alcoholism. The median consultation time was five months. The main circumstance of discovery remains dysphagia (87.1%), followed by aphagia (4.3%) and odynophagia (4.3%). Squamous cell carcinoma is the most represented histological type with 89 patients (95.7%) distributed as follows: 45 women and 44 men. Adenocarcinoma was found in three cases (two men and one woman) and finally one case of adenosquamous carcinoma. CONCLUSION: Squamous cell carcinoma is the most frequent esophagus cancer. It represents the fifth location in our institute and occurs in young patients without gender predominance.

Purpose: To describe the characteristics and recurrence rates of primary periocular squamous cell carcinoma (SCC) in Spain. Methods: This retrospective study investigates the characteristics of primary periocular SCC at two tertiary centers in Spain from 2000 to 2020. Data were collected on demographics, skin phenotype, location, clinical and histological diagnosis, the commitment of surgical margins, recurrence, and risk factors. Multivariate analysis and risk factors were used to investigate recurrence rates, considering p < 0.05 as statistically significant. Results: Over the 20-year studied period, 107 patients with primary periocular SCC were assessed. The mean age of SCC was 76.8 ± 12.8 years, 55 (50.9%) were females, and 105 (98.1%) had Fitzpatrick skin phenotype type II or III. SCC lesions affected less than 1/3 of the eyelid (56/52.3% cases), mainly the lower lid (42/39.3% lesions). Sixty (56.1%) cases were SCC differentiated, 76 (71%) had clear margins. Clinical diagnosis of SCC corroborated with histological in 84 (78.5%) cases and orbital involvement occurred in 18 (16.8%) cases. Recurrence was observed in 13 (12.1%) cases, occurring more in large tumors and undifferentiated subtype (53.8%), with committed margins (69.2%) ( p = 0.001), being the commitment of margins a significant predictor for recurrence, although thickness was an independent predictor. Conclusion: Periocular SCC in Spain showed a similar pattern as in the world. The risk of recurrence is increased in undifferentiated and large periocular SCC, partially removed with committed margins.

The Mean

Pteridium arachnoideum, a fern of the Pteridium aquilinum species complex found in South America, is responsible for several different syndromes of poisoning. Cases of bovine enzootic hematuria and upper alimentary squamous cell carcinoma are both frequent occurrences in Brazil, whereas only bovine enzootic hematuria is noted with any frequency around the world. The reason for the high frequency of upper alimentary squamous cell carcinoma in Brazil is not currently known. One possible explanation may be the higher levels of ptaquiloside and pterosin B in Brazilian Pteridium than those present in the plant in other countries. However, these levels have not yet been determined in P. arachnoideum. Thus, the present study aimed to measure and compare ptaquiloside and pterosin B levels in mature green fronds and sprouts of P. arachnoideum collected from different locations in Brazil. Samples of P. arachnoideum were collected from the states of Minas Gerais and Rio Grande do Sul. A total of 28 mature leaf samples and 23 sprout samples were used. The mean concentrations of ptaquiloside and pterosin B present in the mature green fronds of P. arachnoideum ranged from 2.49 to 2.75 mg/g and 0.68 to 0.88 mg/g, respectively; in P. arachnoideum sprouts, mean concentrations of ptaquiloside and pterosin B ranged from 12.47 to 18.81 mg/g, and 4.03 to 10.42 mg/g for ptaquiloside and pterosin B, respectively. Thus, ptaquiloside and pterosin B levels in P. arachnoideum samples collected in Brazil were higher in sprouts than in mature green fronds, as observed in other countries. However, there was no variation in ptaquiloside levels among plants collected from different cities in Brazil. The high frequency of upper alimentary squamous cell carcinoma in Brazilian cattle may not be attributed to greater levels of ptaquiloside and pterosin B in P. arachnoideum than in other Pteridium species in other countries.

Lingual squamous cell carcinoma is one of the most frequent localization of the oral carcinomas. The tongue neoplasia represents nearly 40% of the oral carcinomas. Recent studies showed an increasing trend of lingual carcinoma in young patients. Several staining tests have been described to early detect the disease. After detection, disease free margins resection will increase the survival rate. This study aims to analyze the methylene blue staining test in achieving disease free resection margins in lingual squamous cell carcinoma.

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.
