The morphologic aspects are reported for 140 cases of nasopharyngeal carcinoma collected from a retrospective review of malignant tumors of this region. Of 97 cases of undifferentiated carcinomas of nasopharyngeal type, 63 were composed of solid cords of epithelial cells (Régaud type), 22 showed isolated cells in a lymphoid stroma (Schmincke type), and in 12 the neoplastic cells were aligned with a fibrosarcoma-like aspect (spindle-cell type). The 36 cases of squamous cell carcinoma showed various degrees of differentiation. Of the remaining 7 cases, 3 were transitional cell carcinomas, 1 was an adenoid cystic carcinoma, and 3 were unclassifiable carcinomas. The undifferentiated carcinoma was present in all ages, with a male: female rate of 1.27:1. The squamous cell carcinomas were prevalent in males (3.5:1) and older patients. The 10-year survival rate was 30% in the group of patients with undifferentiated carcinoma, whereas patients with squamous cell carcinoma died within 4 years of the diagnosis.

A new classification scheme for malignant tumors of the nasopharynx is proposed in which the undifferentiated carcinoma of nasopharyngeal types as a prominent position. This term replaces the previous obsolete term lymphoepithelioma on the basis of its clinicopathologic identity, its separation from squamous cell carcinoma, and its potential origin from anatomical areas other than the nasopharynx.

bjectives: To determine the result of reconstruction with local or regional flaps of skin defects in the temporo-parotid region, after resection of malignant parotid gland and ear tumors, and to establish a reconstruction algorithm according to the size of the defect. Methods: The electronic medical records of the patients who underwent surgery for malignant tumors of the parotid gland and ear with invasion of the skin of the region, and who had reconstructions of the skin defect with local and regional flaps, were selected. The surgeries were performed by the surgical team of the Otorhinolaryngology service of the Italian hospital in Buenos Aires between 2005 and 2018. Results: Five patients were included.There were two malignant parotid gland tumors with histology of adenoid cystic carcinoma and squamous cell carcinoma, and three temporal bone tumors: squamous cell carcinoma, basal cell carcinoma in another and adenoid cystic carcinoma. The reconstructions were made with local or regional flaps. In skin defects smaller than 8cm the reconstructions were made with cervical and scalp flaps. In skin defects larger than 8cm the pectoralis major musculoctaneous flap were used. No patient had partial or total necrosis of the flaps. Conclusions: The results of the reconstructions with local and regional flaps of the skin defects caused by the resection of malignant tumors of the ear and the parotid gland were very good, since they allowed the repair of the defect with a good aesthetic result, without the need to perform grafts in the donor area and with few minor complications. In patients with advanced malignant tumors of the ear and parotid gland with infiltration of the surrounding skin, it is better to do the reconstruction with local or regional flaps due to the greater simplicity and speed of the surgical technique, similar aesthetic results and few complications.

AbstractEsophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors in the digestive system with a high incidence and poor prognosis. Long non-coding RNAs (LncRNA) have been reported to be closely associated with the occurrence and development of various human cancers. Data from GSE89102 shows an increase of THAP9-AS1 expression in ESCC. However, its functions and mechanisms underlying ESCC progression remain to be investigated. In this study, we found that THAP9-AS1 was overexpressed in ESCC tissues and cells. High THAP9-AS1 expression was positively correlated with tumor size, TNM stage, lymph node metastasis, and worse prognosis. Functionally, depletion of THAP9-AS1 suppressed cell proliferation, migration, and invasion, while enhanced apoptosis in vitro. Consistently, knockdown of THAP9-AS1 inhibited xenograft tumor growth in vivo. Mechanistically, THAP9-AS1 could serve as a competing endogenous RNA (ceRNA) for miR-133b, resulting in the upregulation of SOX4. Reciprocally, SOX4 bound to the promoter region of THAP9-AS1 to activate its transcription. Moreover, the anti-tumor property induced by THAP9-AS1 knockdown was significantly impaired due to miR-133b downregulation or SOX4 overexpression. Taken together, our study reveals a positive feedback loop of THAP9-AS1/miR-133b/SOX4 to facilitate ESCC progression, providing a potential molecular target to fight against ESCC.

Adenoid squamous cell carcinoma is an uncommon variant of squamous cell carcinoma. The lesion is histologically distinctive and it is usually localized on the skin of the head and neck region; it only rarely involves the mucosal sites. The differential diagnoses include adenosquamous carcinoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, basaloid squamous cell carcinoma, and metastatic adenocarcinoma. Surgery is the treatment of choice. The biologic behavior of this neoplasm is more aggressive when it involves mucosal areas, and the prognosis seems worse than that of conventional squamous cell carcinoma.

Purpose. Head and neck squamous cell carcinoma (HNSCC) is the most common malignant tumors in the world. Genetic variants have an important role in HNSCC progression. Our study is aimed at exploring the relationship between MIR17HG polymorphisms and HNSCC risk in the Chinese Han population. Methods. We recruited 537 HNSCC cases and 533 healthy subjects to detect the correlation of six polymorphisms in MIR17HG with HNSCC susceptibility. The associations were evaluated by computing odds ratios (ORs) and 95% confidence intervals (CIs) using logistic regression analysis. Results. Our study revealed that rs7336610 (OR 1.77, 95 % CI = 1.09 ‐ 2.86 , and p = 0.021 ) and rs1428 (OR 1.73, 95 % CI = 1.07 ‐ 2.81 , and p = 0.025 ) are strongly associated with increased susceptibility to HNSCC in men. Besides, rs17735387 played a crucial protective role in stage III/IV HNSCC patients (OR 0.34, 95 % CI = 0.12 ‐ 0.95 , and p = 0.040 ) compared with stage I/II. Conclusion. Our study firstly indicated that MIR17HG polymorphisms are significantly associated with HNSCC susceptibility, which suggests that MIR17HG has a potential role in the occurrence of HNSCC.
