Abstract Background Oesophageal submucosal tumours are usually benign. We report a rare case of esophageal squamous cell carcinoma presenting as a submucosal tumour. Case presentation A 58-year-old man undergoing screening oesophago-gastroduodenoscopy was found to have a smooth-surfaced 0.6-cm sized submucosal tumour in the oesophagus 30 cm from the incisor. Endoscopic ultrasonography showed the tumour to be located in the muscularis mucosa; the lesion was heterogeneously hypoechoic and had a clear boundary. With a provisional diagnosis of leiomyoma, the tumour was removed by endoscopic submucosal dissection. Pathological examination showed it to be a moderately differentiated infiltrating squamous cell carcinoma, with normal overlying squamous epithelium. Immunohistochemistry indicated that it was caused by malignant transformation in mucosal glandular duct epithelium. Positron emission tomography–computer tomography showed no tumour spread to any other site. The patient was treated by oesophageal resection. Conclusion The clinician should be aware that oesophageal submucosal tumours with smooth overlying mucosa may not always be benign; malignancy must be ruled out.

A 50-year-old woman with a long history of nasopharyngeal cancer (T2N2M0, squamous cell carcinoma) underwent chemoradiotherapy and surgery. In the past, to prevent tumor recurrence or metastasis, she underwent concurrent chemoradiotherapy or neck dissection. However, during a follow-up 10 years after the surgery, intense F-18 fluorodeoxyglucose uptake was detected in the oral area (SUVmax 6.0). A biopsy of the area with F-18 fluorodeoxyglucose uptake revealed pathological inflammation. Radiography showed the presence of a wisdom tooth, located at the F-18 fluorodeoxyglucose accumulation site, and pericoronitis of this tooth was detected. Our findings indicate the importance of considering the effect of inflammatory conditions, such as periodontal disease, in using F-18 fluorodeoxyglucose positron emission tomography/computed tomography during follow-up after head and neck cancer treatment.

Abstract Background We investigated the expression and clinical significance of miR-141 and miR-340 in cervical squamous cell carcinoma (CSCC). Methods Expression of miR-141 and miR-340 in CSCC, high-grade squamous intraepithelial lesion (HSIL), and normal cervical squamous epithelium were detected by qRT-PCR. PTEN was assessed by immunohistochemistry. Their relationship with clinicopathological features was analyzed. Results The changes of miR-141 and miR-340 were different in CSCC, HSIL, and normal squamous epithelium (P = 0.030). miR-141 expression was statistically significant in gross type, differentiation, uterine corpus invasion, nerve invasion, vagina invasion, and FIGO stage in CSCC (P < 0.05). miR-340 expression was related to tumor size, differentiation, nerve invasion, lymph node metastasis, and FIGO stage in CSCC (P < 0.05). miR-141 and miR-340 expressions were statistically significant in different ages (P < 0.05) in HSIL. The AUC of miR-141 in CSCC diagnosis and that of miR-340 in HSIL diagnosis were 0.893 and 0.764, respectively. The sensitivity and the specificity of miR-141 for diagnosis of CSCC were 95.0% and 60.8%, respectively, while those of miR-340 for diagnosis of HSIL were 90.0 and 48.6%, respectively. miR-141 and miR-340 expressions are associated with PTEN expression (P = 0.002 and P < 0.001). Conclusion miR-141 and miR-340 may be associated with their target gene PTEN and involved in the carcinogenesis of cervical squamous epithelium.

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.

Abstract   Lymph node(LN)metastasis is a common metastasis mode of esophageal squamous cell carcinoma (ESCC). The purpose of this study is to explore whether recurrent laryngeal nerve LNs metastasis can be used as a predictor of cervical LN dissection. Methods The postoperative pathological examination results of patients with ESCC who underwent three-field LN dissection in Sichuan Cancer Hospital from January 2010 to January 2016 were retrospectively collected to explore the relationship between the recurrent laryngeal nerve LN metastasis and cervical LN metastasis. At the same time, analyzed survival data to determine whether cervical LN dissection should be performed on patients with thoracic ESCC. Results Among all the study subjects, 53.3% (72/135) patients had metastasis in the thoracic recurrent laryngeal nerve LNs, and 36.3% (49/135) patients had metastasis in the cervical LN. 44.4% (32/72) Patients with metastasis in the thoracic recurrent laryngeal nerve LN tended to have a high incidence of cervical LN metastasis (P = 0.035). Subgroup analysis showed that 60% (81/135) patients had upper thoracic ESCC, and 46.9% (38/81) patients had cervical LN metastasis (P = 0.002). Survival analysis showed that patients with cervical LN metastasis had poor survival (P &lt; 0.001). Multivariate analysis showed that bilateral recurrent laryngeal nerve LN metastasis was an independent risk factor for survial(P = 0.029). Conclusion Patients with bilateral recurrent laryngeal nerve LN metastasis in upper thoracic ESCC can be used as a predictor of cervical LN dissection.
