RESUMEN
Background: Odontogenic myxoma is one of the benign mesenchymal odontogenic tumours with aggressive behaviour and showed slow and asymptomatic expansion, the second until the third decade of life is the most targeted age group. With high female preponderance, about the management, surgical management is the only option concerning this odontogenic pathology with a variety of treatment options. This study aims to analyse a series of 37 patients with odontogenic myxoma treated in a single institution. Materials and method: In total, 37 patients with odontogenic myxoma were treated at KTDH in Sudan and were retrospectively reviewed. With the analysis of medical records of all patients diagnosed with odontogenic myxoma and the related variables, data were analysed using the SPSS statistical program (version 23). Results: Most of the cases were females (26 patients 70.27%), and males were about (11 patients 29.73%). In most of the cases maxilla was affected more than the mandible (25 cases, 67.57%) mostly in its posterior segment (32 cases, 86.49). The most age group affected was the group of cases (0-20) which were about 18 cases (48.65%). In total, 35 of the cases noticed swelling (94.59%), while 14 noticed tooth mobility (37.84%) and paraesthesia was a positive finding in just one case (2.70%). In total, 12 patients (32.43%) had a positive history of tooth extraction related to the lesion, and recurrence was positive in (64, 86%). Conclusion: Odontogenic myxoma is locally aggressive. There is no gold standard protocol for surgical treatment so choosing the most suitable and reliable treatment option relay on the operator taking into consideration the characteristic of each case and the recurrence rate with the associated postoperative impairments.
RESUMEN
Objectives This study aimed to investigate the potential prognostic role of the oral cancer systemic inflammation score (SIS) based on serum albumin levels and the lymphocyte-to-monocyte ratio in patients with oral squamous cell carcinoma (OSCC) after treatment. Study Design A retrospective cohort study. Setting Tertiary care center. Subjects and Methods The study involved 613 patients who were treated for OSCC between September 2005 and December 2014. The association of the oral cancer SIS with various clinicopathological features was investigated. A nomogram based on different clinicopathological features and SIS was established to predict prognosis. Results Higher SIS was significantly associated with older age ( P = .0013), advanced tumor status ( P < .0001), tumor depth ( P < .0001), advanced overall pathologic stage ( P < .0001), and extranodal extension ( P = .0045), as well as the presence of perineural invasion ( P = .0341). Higher SIS, older age, overall stage, and extranodal extension were demonstrated to be independent prognostic indicators for shorter overall survival ( P < .0001). A nomogram comprising SIS, TNM stage, and the degree of cell differentiation, as well as perineural invasion and extranodal extension, was developed to predict the prognosis of these patients. The c-index of the nomogram model based on TNM staging only was 0.688 and could be increased to 0.752 if SIS and several other clinicopathological parameters were incorporated. Conclusions Higher SIS is associated with many poor prognosticators, and the nomogram that was established and based on the incorporation of SIS might strengthen the prediction of prognosis in patients with OSCC.
