Systematic review of risk factors of postoperative dysphagia in patients with oral cancer

OBJECTIVES

This study aims to identify risk factors of postoperative dysphagia in patients with oral cancer by systematic review.

METHODS

Cohort studies in Chinese or English on risk factors of postoperative dysphagia in patients with oral cancer were searched from CNKI, Wanfang database, VIP Chinese Journal Database, China Biomedical Literature Service System, Chinese Clinical Trial Registry, PubMed, Cochrane Library, EMBASE, Web of Science, and Clinical Trials from the beginning to June 30, 2021. Subject words combined with free words were used to retrieve related articles. The included studies were evaluated, and the effective data were processed with Revman 5.3.

RESULTS

Ten studies were selected, and they included 1 241 patients consisting of 473 patients in the exposed group and 768 patients in the control group. After the meta-analysis, the risk factors with statistical significance were as follows: age>60 years, tumor located in oropharynx or mouth floor, tumor size of T3 or T4, TNM stage of Ⅳ, resection involving suprahyoid muscle or tongue resection>50%, combination of neck dissection, tracheotomy, or reconstruction, and postoperative radiotherapy.

CONCLUSIONS

Age>60 years, tumor in oropharynx or mouth floor, tumor size of T3 or T4, TNM stage of Ⅳ, resection involving suprahyoid muscle or tongue resection>50%, combination of neck dissection, tracheotomy, or reconstruction, and postoperative radiotherapy were significant risk factors of postoperative dysphagia in patients with oral cancer.

Extraosseous Ewing's Sarcoma: Pictorial Review of Imaging Findings, Differential Diagnosis, and Pathologic Correlation

Extraosseous Ewing's sarcoma (EES), first described in 1969, is a malignant mesenchymal tumor just like its intraosseous counterpart. Although Ewing's sarcomas are common bone tumors in young children, EESs are rarer and more commonly found in older children/adults, often carrying a poorer prognosis. We discuss the multimodality imaging features of EES and the differential diagnosis of an aggressive appearing mass in proximity to skeletal structures, with pathologic correlates. This review highlights the need to recognize the variability of radiologic findings in EES such as the presence of hemorrhage, rich vascularity, and cystic or necrotic regions and its imaging similarity to other neoplasms that are closely related pathologically.

Image-guided percutaneous cryo-ablation of peri-urethral unresectable recurrent pelvic malignancy: A case report and brief review

Recurrent or metastatic peri-urethral pelvic malignancies are a difficult-to-treat entity. Re-resection is recommended when possible but is frequently unfavorable due to scar tissue, fibrosis, and obliteration of tissue planes following previous interventions such as surgical resection and/or radiation therapy. Curative options for patients that have unresectable cancer are limited. Cryo-ablation has been extensively studied in the treatment of unresectable renal, liver and lung malignancies and has the potential to provide definitive treatment for recurrent pelvic malignancy. There is a paucity of reports of salvage cryo-ablation in patients with recurrent pelvic malignancies, as most of these tumors are located close to critical structures that could be irreversibly injured by thermal ablation and are hence treated with some form of radiation therapy. But, for patients who fail surgical and radiation treatments, options are limited. Here, we describe two cases of regional tumor recurrence in the pelvis treated with percutaneous cryoablation using protective techniques to avoid thermal injury to adjacent structures. In each case, cryo-ablation was performed successfully despite extensive previous surgical and radiation interventions. Salvage cryo-ablation resulted in a positive clinical and imaging response with an improvement in quality of life and absence of recurrence on follow-up imaging which continues to persist at the writing of this manuscript about 8 and 12-months following treatment.
