Deng R, Li NJ, Bai LL, Nie SH, Sun XW, Wang YS. Postoperative radiotherapy for thymus salivary gland carcinoma: A case report. World J Clin Cases 2022; 10:9484-9492. [PMID: 36159414 PMCID: PMC9477657 DOI: 10.12998/wjcc.v10.i26.9484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/12/2022] [Accepted: 07/31/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Salivary gland cancer is a rare disease in which cancer cells form in the tissues of the salivary glands. It mostly occurs in the glands that have secretion functions, such as the parotid gland, sublingual gland and submandibular gland. This is very rare when it occurs in other nonsecreting glands. Here, we report one case of salivary gland carcinoma occurring in the thymus and discuss related diagnoses and treatment progress.
CASE SUMMARY One 33-year-old middle-aged man presented with a thymus mass without any clinical symptoms when he underwent regular physical examination. Later, the patient was admitted to the hospital for further examination. Computed tomography (CT) showed that there was a mass of 3 cm × 2.8 cm × 1.5 cm in the thymus area. The patient had no symptom of discomfort or tumor- related medical history before. After completing the preoperative examinations, it was confirmed that the patient had indications for surgery. The surgeon performed a transthoracoscope "thymectomy + pleural mucostomy" for him. During the operation, the tumor tissue was quickly frozen, and the symptomatic section showed a malignant tumor. The final pathological result suggested thymus salivary gland carcinoma- mucoepidermoid carcinoma (MEC). In the second month after surgery, we performed local area radiotherapy for the patient, with a total radiation dose of 50.4 Gy/28Fx. After 12 mo of surgery, the patient underwent positron emission tomography-CT examination, which indicated that there was no sign of tumor recurrence or metastasis. After 16 mo of operation, CT scan re-examination showed that there was no sign of tumor recurrence or metastasis. As of the time of publication, the patient was followed up for one and a half years. He had no sign of tumor recurrence and continued to survive.
CONCLUSION The incidence of MEC in the thymus is low, and its diagnosis needs to be combined with clinical features and imaging methods. Histopathological analysis plays a key role in the diagnosis of the disease. Patients with early-stage disease have a good prognosis and long survival period. In contrast, patients with advanced-stage disease have a poor prognosis and short survival period. Combining radiotherapy and chemotherapy in inoperable patients may prolong survival.

Abstract
BACKGROUND Adenocarcinoma not otherwise specified (AdCaNOS) is a rare malignant salivary gland tumor that occurs with higher frequency in the parotid gland of male patients. In this study, we described a second case of AdCaNOS arising in the sublingual gland, in a female patient with 39 years of age, highlighting the clinical, radiographic, microscopic, treatment features and follow-up. CASE REPORT A 39-year-old female patient presented a fibroelastic nodule with a yellowish coloration, in the left region of the floor of mouth, measuring about 4.0 cm in its largest diameter. An incisional biopsy was performed and the main microscopic features revealed an infiltrative lesion with glandular differentiation organized in cystic spaces, where neoplastic cells secreting eosinophilic material were observed. The tumor showed immunopositivity for pancytokeratin (AE1/AE3), keratins 7 (CK7) and 14 (CK14), and negativity for p63. The proliferation level measured by Ki-67 marker was considered higher. The patient underwent radical surgical resection, but unfortunately, she developed local recurrence, lymph node mestastasis and died 1.5 year after diagnosis. CONCLUSION Although rare in the sublingual gland, particularly at this age, AdCaNOS can occur and early diagnosis and early treatment are essential for a better prognosis and survival rates of the patients.

Abstract
AIM To evaluate the potential use of Cephaeline as a therapeutic strategy to manage mucoepidermoid carcinomas (MEC) of the salivary glands. MATERIAL AND METHODS UM-HMC-1, UM-HMC-2, and UM-HMC-3A MEC cell lines were used to establish the effects of Cephaeline over tumor viability determined by MTT assay. In vitro wound healing scratch assays were performed to address cellular migration while immunofluorescence staining for histone H3 lysine 9 (H3k9ac) was used to identify the acetylation status of tumor cells upon Cephaeline administration. The presence of cancer stem cells was evaluated by the identification of ALDH enzymatic activity by flow cytometry and through functional assays using in vitro tumorsphere formation. RESULTS A single administration of Cephaeline resulted in reduced viability of MEC cells along with the halt on tumor growth and cellular migration potential. Administration of Cephaeline resulted in chromatin histone acetylation as judged by the increased levels of H3K9ac and disruption of tumorspheres formation. Interestingly, ALDH levels were increased in UM-HMC-1 and UM-HMC-3A cell lines, while UM-HMC-2 showed a reduced enzymatic activity. CONCLUSION Cephaeline has shown anti-cancer properties in all MEC cell lines tested by regulating tumor cells' viability, migration, proliferation, and disrupting the ability of cancer cells to generate tumorspheres.

Abstract
Mucoepidermoid carcinoma (MEC) of the palate is a common malignancy of minor salivary glands. This study was designed to identify the prognostic factors for MEC of the palate. The medical records of patients diagnosed with MEC of the palate who visited the Department of Oral and Maxillofacial Surgery at Nanjing Stomatological Hospital and the Department of Stomatology at Central Hospital of Xuzhou were retrospectively studied. The prognostic factors were determined using a Cox proportional hazards model. Furthermore, the expression of cancer stem cell (CSC) markers CD44, CD133, Nanog and Sox2 were detected in neoplastic samples of these patients by immunohistochemistry. As a result, both univariate analysis and multivariate analysis proved a high histological grade and an advanced tumor stage as negative prognostic factors for overall survival. By immunohistochemistry staining and survival analysis, a combination of CD44/CD133/SOX2 was found to have the strongest prognostic value for palatal MEC patients. In conclusion, the proposed nomogram which include histological grade and tumor stage along with cancer stem cell markers provides a more accurate long-term prediction for palatal MEC patients.

Abstract
Carcinoembryonic antigen is a tumour marker commonly increased in gastrointestinal and pulmonary cancers. We report a case of a 46-year-old man with a mucoepidermoid carcinoma of the base of tongue with an elevated and traceable serum carcinoembryonic antigen level. This antigen proved to be a valuable marker in the treatment follow-up. When a raised carcinoembryonic antigen level is found, salivary gland malignancies should be taken into the differential diagnosis and clinical examination of the head and neck region should not be overlooked.

Abstract
A detailed clinical examination is important for early diagnosis of oral lesions in every dental specialty, including orthodontics, particularly because these patients are constantly checked during orthodontic treatment. This report describes 2 men receiving orthodontic treatment and who had swelling on the hard palate diagnosed as mucoepidermoid carcinoma. Both patients received appropriate treatment and had a good prognosis because of the rapid recognition of these oral lesions by their orthodontists.

Abstract
BACKGROUND Histopathologic grade of mucoepidermoid carcinoma (MEC) is an established predictor of prognosis and affects treatment protocol. Tumor behavior is more aggressive in high-grade than in low-grade MEC, leading to a more intensive treatment protocol. Outcomes for patients with intermediate-grade MEC are less clear; therefore, the optimal treatment protocol for this group is not well defined. The treatment protocol and survival outcomes of patients treated for MEC of the head and neck was investigated. METHODS A retrospective clinical review and prospective review of histopathologic grading were undertaken using the most recently established grading system of 50 patients with MEC of the head and neck from 1983 through 2004. RESULTS As histologic grade increased from low to intermediate to high, overall survival (P < .0001) and disease-free survival (P < .001) were significantly decreased. Overall and disease-free survival were significantly better for patients with intermediate-grade MEC than those with high-grade disease. Overall and disease-free survival were similar for patients with low-grade and intermediate-grade MEC. There was a low rate of disease recurrence in patients with intermediate-grade MEC, but this did not lead to death from disease. Although no patients with low-grade or intermediate-grade MEC died of disease, 52% of patients with high-grade MEC died of disease. Multivariate analysis revealed that histologic grade, age, and surgical margin status significantly predicted prognosis. CONCLUSIONS These findings suggest that, under the current histopathologic classification system, the behavior of intermediate-grade MEC is comparable to that of low-grade MEC and different from high-grade MEC, allowing for the establishment of an evidence-based treatment protocol.

Abstract
PURPOSE The purpose of this study was to assess the clinicopathologic, treatment, and outcome features of a series of intraoral mucoepidermoid carcinomas (MECs) affecting children and adolescents. PATIENTS AND METHODS Between 1953 and 2006, from 102 intraoral MECs, 9 (8.8%) affected patients under 18 years of age. Clinical data were retrieved from the medical records, the microscopical slides reviewed, and the tumors graded in low, intermediate, and high grades of malignancy. RESULTS Five cases occurred in females and 4 in males, with a mean age of 14 years. Seven cases affected the palate, and the other 2 occurred in the buccal mucosa and retromolar area. Most patients presented in initial clinical stages and all cases were surgically treated. Microscopically, 7 tumors were classified as histologically low-grade malignancies. Eight patients did not show tumor recurrence after a mean follow-up of 98.4 months (range, 4 to 278 months), and 1 patient developed local and neck recurrences and died after 15 years of initial treatment. CONCLUSION Juvenile MEC are rare tumors, most occur in the palate and present as a low-grade malignancy with excellent prognosis. Although rare, MEC should be considered in the differential diagnosis of intraoral submucous nodule in young patients.
