Abstract
OBJECTIVES Oral cancer is the eighth most common type of cancer worldwide and a significant contributor to the global burden caused by this disease. The principal parameters considered to influence prognosis, and thus treatment selection, are size and location of the primary tumor, as well as assessment of the presence and extent of lymph node and distant metastasis (DM). However, no known report regarding the relationship between the primary site and DM has been presented. For effective treatment selection and good prognosis, the correlation of DM with anatomic site and histopathology results of the primary malignancy is important. In the present study, we performed a systematic review of published reports in an effort to determine the relationship between the anatomic site of various types of oral cavity cancer and DM. METHODS A systematic review of articles published until the end of 2018 was performed using PubMed/MEDLINE. RESULTS A total of 150 studies were selected for this review. The percentage of all cases reported with DM was 6.3%, ranging from 0.6% to 33.1% in the individual studies. The rate of incidence of tongue occurrence was 9.3%. A frequent DM site was the lungs, with adenoid cystic carcinoma the most commonly involved histopathological factor. Malignant melanoma was most frequent (43.4%) in all histopathology findings, whereas there were no cases with an acinic cell carcinoma or cystadenocarcinoma. CONCLUSIONS We found that the occurrence of DM from the primary site as well as rate of incidence was dependent on histopathological factors.

The value of preoperative radiotherapy in the treatment of locally advanced nasal cavity and paranasal sinus squamous cell carcinoma: A single institutional experience. Oral Oncol 2019; 101:104512. [PMID: 31869689 DOI: 10.1016/j.oraloncology.2019.104512] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 11/28/2019] [Accepted: 12/03/2019] [Indexed: 02/02/2023]
Abstract
OBJECTIVES This study aimed to explore the value of preoperative radiotherapy in the comprehensive treatment of locally advanced nasal cavity and paranasal sinus squamous cell carcinomas (LA-NPSCCs). MATERIALS This retrospective study included 140 patients with stage III-IVB NPSCCs treated with pre-/postoperative radiotherapy plus surgery. The complete resection rate, pathologic complete response (pCR) rate, and orbital content retention rate were calculated. The overall survival (OS), local control (LC), distance metastasis free survival (DMFS) and disease-free survival (DFS) between treatment groups were evaluated. RESULTS With a median follow-up of 92.3 months, the 5-year OS, LC, DMFS, and DFS of entire cohort were 62.0%, 65.5%, 85.4%, and 57.8%, respectively. The preoperative radiotherapy group achieved similar LC, DFS, DMFS, and OS rates compared to postoperative radiotherapy group, despite higher rates of stage IV and orbital content/apex invasion. The preoperative radiotherapy resulted in significantly improved complete resection rate (93.3% vs 38.0%, p < 0.001). In the preoperative radiotherapy group, one third of patients achieved pathologic complete response. The pCR subgroup achieved statistically higher 5-year OS, LC, DFS (p < 0.05), but similar 5-year DMFS (p > 0.05) compared to non-pCR subgroup. The actual orbital content retention rate in preoperative radiotherapy group was 85.7%, superior to 58.3% in postoperative radiotherapy group (p = 0.049). CONCLUSION On the basis of multimodality therapy becoming standard paradigm for LA-NPSCCs, preoperative radiotherapy significantly improved complete resection rate and orbital content retention rate. Therefore, preoperative radiotherapy followed by surgery might be desirable for LA-NPSCCs, especially for those with organ preservation intention.

Abstract
Impairment of neurogenesis in the hippocampus following whole-brain irradiation is the most important mechanism of radiation-induced cognitive dysfunction. However, the underlying mechanism remains obscure, meaning an ideal therapeutic target has not been identified. Evidence indicates that DNA methylation in neurons regulates synaptic plasticity and neuronal network activity. In the present study, the expression of DNA methyltransferases (DNMTs) in the hippocampus was analyzed to investigate their potential function in radiation-induced neurogenesis impairment. Sprague-Dawley rats were used throughout the present study, apportioned to the following groups: Control, radiation only, zebularine (a DNMT inhibitor) only, and radiation and zebularine together. Immunofluorescence staining revealed that radiation inhibited cellular proliferation and dendritic growth within new neurons of the hippocampus. In addition, western blot analysis demonstrated lower expression levels of DNMT1 and DNMT3A protein following radiation treatment compared with that in the non-irradiated control. Furthermore, compared with the radiation-only group, the radiation and zebularine group had significantly lower cell proliferative abilities, dendritic growth, and DNMT1 and DNMT3A protein levels. The results of the present study indicated that DNMT1 and DNMT3A may be involved in the pathogenesis of whole-brain radiation-induced neurogenesis impairment.

Importance of chewing, saliva, and swallowing function in patients with advanced oral cancer undergoing preoperative chemoradiotherapy: a prospective study of quality of life. Int J Oral Maxillofac Surg 2017; 46:1229-1236. [PMID: 28579265 DOI: 10.1016/j.ijom.2017.05.005] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 03/07/2017] [Accepted: 05/10/2017] [Indexed: 11/26/2022]
Abstract
The primary objective of this study was to investigate the quality of life (QOL) of patients with oral squamous cell carcinoma (OSCC) undergoing curative neoadjuvant chemoradiotherapy followed by radical tumour resection and simultaneous oral cavity reconstruction, using two validated questionnaires. A secondary objective was to assess clinical variables predicting post-treatment dysfunction in chewing, saliva, and swallowing. Thirty-five patients with locally advanced OSCC who underwent preoperative chemoradiotherapy were recruited prospectively. All patients completed both the University of Washington Quality of Life version 4 questionnaire (UW-QOL) and the Functional Assessment of Cancer Therapy-Head & Neck version 4 questionnaire (FACT-H&N). UW-QOL and FACT-H&N items were associated with clinical variables. Nearly three-quarters of OSCC patients perceived good to excellent levels of overall QOL after preoperative chemoradiotherapy. Chewing difficulties, decreased salivary function, and swallowing dysfunction were the most frequent complaints of OSCC patients. Items related to food intake were significantly worse in OSCC patients older than 60 years and those with T4 tumours, as well as those without alcohol intake. Chewing, saliva, and swallowing are the most significant issues in patients with OSCC undergoing preoperative chemoradiotherapy. The results of this study may help guide treatment decisions for OSCC patients based on more accurate expectations of adverse effects of cancer treatment.
