RESUMO
Background: Multiple primary squamous cell carcinomas (MPSCs) of the oral cavity are very uncommon in clinical practice. This study describes the clinical features, imaging, and treatment characteristics of the oral cavity with MPSCs at the same time of diagnosis in our center. Besides, we review the literature and prior studies on MPSCs. Study design: A retrospective, descriptive study from January 2019 to December 2021 was conducted on seven patients with MPSCs of the oral cavity at the time of their first diagnosis. Evaluation of the patient's characteristics, the treatment plan, the response to treatment, and the overall survival (OS). Results: Seven male patients ranging in age from 43 to 70 years (Mean: 53.5). Positron Emission Tomography/Computed Tomography (PET/CT) revealed a significantly increased standardized uptake value (SUV) in the index tumor (SUVi = 15.76 ± 1.96). The index tumor is often staged T3, T4; whereas the synchronous tumor is typically staged T1, T2. All patients had concurrent chemoradiotherapy (CCRT) and achieved a partial response in all cases. Mean OS was 14.71 ± 11.85 months. Conclusions: MPSCs of the oral cavity at the time of diagnosis are uncommon and associated with a poor prognosis for patients. Comprehensive clinical examination, combined imaging diagnostics, with PET/CT being critical for detecting the second lesion, particularly in patients with an advanced index tumor.
RESUMO
Objectives: Evaluation of the hemostatic effect of trans-arterial embolization on patients with advanced oral cavity cancer who had bleeding complications while undergoing definitive concurrent chemoradiotherapy (CCRT). Additionally, assess the effect of trans-arterial embolization on treatment response following concurrent chemoradiotherapy, as well as overall survival (OS) and progression-free survival (PFS) in the group of patients following the intervention.Method: From September 2018-June 2021, a retrospective descriptive study was conducted on 16 patients with inoperable, locally advanced oral cavity cancer who received definitive concurrent chemoradiotherapy, experienced acute bleeding complications, and received selective intravascular intervention with various embolization materials at Vietnam National Cancer Hospital.Results: After selective embolization, 16/16 patients ceased bleeding; 1 patient re-bled for the second time after 3 weeks. The average duration of chemoradiotherapy interruption due to intervention was 6.7 days. After CCRT, 15/16 (93.75%) patients achieved a response, with 9/16 (56.25%) patients achieving a complete response. The median OS was 14 months (range, 3-26 months), and the median PFS was 10 months (range, 3-20 months). There were no significant complications, particularly neurological side effects.ConclusionsTumor bleeding is a common and serious complication of CCRT treatment in patients with locally advanced oral cavity cancer. Embolization is a safe and effective method of controlling acute bleeding that has no adverse effect on the outcome of definitive concurrent chemoradiotherapy.
RESUMO
The purpose of this research study was to assess the safety and surgical outcomes of endoscopic thyroidectomy applied via a unilateral axillobreast approach with CO2 insufflation to one-sided benign thyroid tumors in Vietnam. Only 1 patient of the 50 (2%) had a postoperative hematoma at the surgery site. Open surgical conversions did not occur. The duration of postoperative drainage was from 3 to 8 days, or 4.86±1.24 days on average. The length of stay in the hospital after surgery was 4 to 9 days, or 5.9±1.2 days on average. The postoperative pain in the first postoperative days was lower in intensity compared with open surgeries. The given method provided better results in terms of patient satisfaction with the cosmetic effect of the surgery compared with up-front surgery, minimally invasive video-assisted thyroidectomy, and endoscopic procedures via the breast approach, and 96% of patients were completely satisfied.
