[Quality of Life After High-dose Brachytherapy in Patients with Early Oral Carcinoma]. / Kvalita zivota pacientu s castými nádory dutiny ústní lécených pooperacní brachyterapií s vysokým dávkovým príkonem pro tesné nebo pozitivní okraje.

BACKGROUND: The prevalence of head and neck tumors has continually increased over the past decades, which is a serious medical and social problem. This study retrospectively assessed the quality of life of patients with early-stage oral cavity tumors after high-dose rate (HDR) brachytherapy. MATERIAL AND METHODS: Quality of life was evaluated in 14 patients with early-onset oral cavity tumors who underwent HDR brachytherapy at the Department of Oncology and Radiotherapy, University Hospital Hradec Kralove. The standardized EORTC QLQ-C30 and EORTC QLQ-H&N 35 questionnaires were used. Patients completed these questionnaires at 12 months after treatment. RESULTS: The general health status was scored 70 points using the EORTC QLQ-C30 questionnaire. Fatigue, insomnia, loss of appetite, dyspnea, and financial problems were the most severe problems reported. The main problems identified by the EORTC QLQ-H&N 35 questionnaire were weight gain, coughing, pain, sticky saliva, and difficulties eating in public. On the contrary, patients did not significantly suffer weight loss, speech impairments, difficulties in mouth opening or swallowing, or sensory problems. CONCLUSION: HDR brachytherapy is an effective treatment for early oral cancer that leaves patients with an acceptable quality of life. A prospective, multicentric study focused on the quality of life of patients with head and neck tumors is required.Key worlds: oral cancer - brachytherapy - quality of life This article was supported by grant PROGRES Q 40/13.

Deep Neck infections of Odontogenic Origin and Their Clinical Significance. A Retrospective Study from Hradec Králové, Czech Republic.

INTRODUCTION: Cellulitis remains a very serious disease even today. Mortality, which varied between 10-40%, has been reduced owing to the standard securing of airway patency and use of an appropriate surgical treatment approach. MATERIALS AND METHODS: A total of 195 patients were hospitalised for cellulitis at the University Hospital in Hradec Králové during 2007-2011. The following parameters were evaluated: age, gender, dependence of incidence of the disease on the season of the year, frequency of attacks of the particular areas and their clinical characteristics, aetiology of the inflammation, types of patient complaints, prevalence of current systemic diseases, results of microbiological and selected laboratory analyses, socio-economic status of the patients, and duration of patient stay at the hospital. Statistical analysis was performed by using Pearson's correlation coefficient, the statistical significance level was p < 0.05. RESULTS: The mean age of the patients was 39.8 years. The group of 195 patients included 108 (55%) males and 87 (45%) females. The mean time between the first symptoms of the disease and admission to the Department was 5 days. From among the 195 patients, 116 (59.5%) were working persons, 79 (40.5%) were non-working (children, students, unemployed persons, women on maternity leave, retired people). The odontogenic origin of the disease was verified in 173 (88.7%) patients. In total, 65 (33.3%) patients had no coinciding complicating systemic disease, 22 (11.3%) patients had diabetes mellitus. The most frequent symptom of cellulitis was painful swelling, found in 194 (99.5%) patients, followed by jaw contracture, found in 153 (78.5%) patients. CONCLUSION: The results are largely very similar to those of previous studies performed in other countries, except that we found no correlation between the prevalence of cellulitis and the socio-economic status, nor have we confirmed Klebsiella pneumoniae sp. as the cause of cellulitis in patients with diabetes mellitus.

Hyperfractionated high-dose rate brachytherapy in the treatment of oral tongue cancer.

BACKGROUND: Low-dose rate brachytherapy is a well established treatment modality of oral cancer. Data about high-dose rate (HDR) brachytherapy are still sparse with various fractionation schedules and heterogeneous results. AIM: The aim of our retrospective study was to evaluate the results of HDR brachytherapy with doses of 3 Gy twice daily. PATIENTS AND METHODS: Twenty patients with squamous cell tongue cancer were treated in the years 2001-2009 by exclusive HDR BT 18 × 3 Gy twice daily. The plastic tube technique was used. Median follow up was 47 months (7.8-118) since brachytherapy. RESULTS: The local and locoregional control was 85% and 68%, respectively. Bone necrosis developed in one case treated without mandibular shielding and soft tissue necrosis in 2 cases. CONCLUSION: It can be concluded that HDR brachytherapy with 18 × 3 Gy twice daily is safe with promising local control. The risk of nodal recurrences is substantial.

High-dose-rate brachytherapy in early oral cancer with close or positive margins.

PURPOSE: Retrospective evaluation of high-dose-rate brachytherapy (HDR BT) in early oral cancer and factors influencing tumor control. METHODS AND MATERIALS: A total of 30 patients with T1-T3N0 tongue and floor of mouth cancer were treated with tumor excision±elective neck dissection and HDR BT 18×3 Gy b.i.d. The Kaplan-Meier model was used for survival analyses, and the log-rank test and Cox regression analyses were used to evaluate the influence of T-stage, histologic grade, resection margin, depth of invasion, and vascular endothelial growth factor (VEGF) intensity on local control (LC), nodal control (NC), disease-free survival (DFS), and overall survival (OS). Median followup was 40 months (6-145). RESULTS: Actuarial 3-year LC, NC, DFS, DFS after salvage treatment, and OS were 85.4%, 69.2%, 65.4%, 75.6%, and 73.0%, respectively. The log-rank test and univariate Cox regression analysis revealed the following correlations, namely tumor grade correlated with LC, DFS, and OS; T-stage with NC and DFS; depth of invasion and VEGF intensity with NC, DFS, and OS. Associations detected on the multivariate analysis were as follows: tumor grade with LC, depth of invasion with NC, depth of invasion and tumor grade with DFS, and VEGF intensity with DFS after salvage treatment. Only one case of osteoradionecrosis and two cases of soft tissue necrosis occurred. CONSLUSION: The HDR BT 18×3 Gy b.i.d. is a safe treatment of early oral cancer with a good LC. The T-stage, tumor grade, depth of invasion, and intensity of VEGF were significant predictors of locoregional control.

Plasma cell granuloma of the oral cavity: a mucosal manifestation of immunoglobulin G4-related disease or a mimic?

The aim of the study was to test the hypothesis that oral plasma cell granuloma may represent a mucosal manifestation of immunoglobulin (Ig)G4-related disease (IgG4-RD) in the oral cavity. The study sample comprised two males and four females, aged 54-79 years (median 62 years). The lesions were localized on gingival/alveolar mucosa (four cases), hard palate, and floor of the mouth, measuring 17-40 mm (median 31 mm). The duration of the lesions ranged from 3 months to several years. Information on IgG4 serum levels was available for two patients, and these were increased to 1.85 and 1.65 g/L, respectively. The follow-up period ranged 11-30 months (median 13 months). None of the lesions recurred, and none of the patients developed any manifestation of IgG4-RD. Microscopically, all cases presented as nodular lesions composed of numerous polyclonal plasma cells admixed with lymphocytes, histiocytes, mast cells, and eosinophils, set within collagenized stroma in variable proportions. Obliterative phlebitis was observed in two cases. The number of IgG4-positive plasma cells ranged between 51 and 142 per HPF (median 114), while the IgG4/IgG ratio values ranged between 0.16 and 0.72 (median 0.44) and were above 0.40 in three cases. Based on international criteria, two cases were diagnosed as definite and one as probable IgG4-RD. Oral plasma cell granuloma is a heterogeneous group of lesions, and a subset may represent a mucosal manifestation of IgG4-RD in the oral cavity.
