Nutritional Status and Quality of Life in Patients with Oral Squamous Cell Carcinoma Before and After Surgical Oncological Treatment: A Single-Center Retrospective Study.

BACKGROUND Oral squamous cell carcinoma (OSCC) is the most common of head and neck malignancies in well-developed countries. In most cases, patients with OSCC experience a degree of nutritional status disturbances and decreased quality of life (QoL). This study aimed to compare nutritional status and QoL in 51 patients before and after surgery for OSCC. MATERIAL AND METHODS Fifty-one eligible patients with OSCC were followed during a 3-year period (2019-2022). For all patients, we determined body mass index (BMI), serum albumin (ALB), prognostic nutritional index, and nutritional risk index before and after treatment. Also, all patients completed a standardized QoL questionnaire before and after treatment. The obtained data were compared between the groups by using the t test and multivariate Cox regression. RESULTS The values of BMI and NRI were statistically significantly different between the preoperative and postoperative measurements (24.1 kg/m² vs 21.1 kg/m², and 103 vs 100.1, respectively, P=0.001), while values of ALB and prognostic nutritional index did not differ significantly (41.35 g/L vs 39.1 g/L, and 48.5 vs 46.2, respectively). Dysphagia (P=0.03) and chewing problems (P=0.04) were found to be the 2 most important factors decreasing the QoL of patients. CONCLUSIONS Based on our results, BMI and NRI were the most sensitive parameters of nutritional status. Dysphagia and chewing problems were the 2 most important factors affecting the QoL in patients with OSCC.

Use of 2-Octyl-Cyanoacrylate in surgical closing of Postparotidectomy salivary fistulas.

A salivary fistula is one of possible postoperative complications in the surgery of parotid gland tumors. We present three cases of postparotidectomy salivary fistulas, successfully treated by surgical access using 2-octyl-cyanoacrylate while closing the skin layer. The previous treatment of these cases by other therapeutic options did not give satisfactory results. In a 5-year follow-up period there were no signs of fistulas relapses. The surgical access with use of 2-octyl cyanoacrylate can be one of therapeutic options for the closing of postparotidectomy salivary fistulas, especially in cases where other therapeutic accesses are not successful.

[MALT lymphoma of the parotid salivary gland].

BACKGROUND: Mucosa-associated lymphoid tissue (MALT) lymphoma was described for the first time in 1983 by Isaacson and Wright. It was classified into extranodal non-Hodkin's lymphomas of B-cell lymphocytes of the marginal zone of reactive lymphe follicles. It is characterized by both hyperplasia and colonization of plasmocytic, centrocytoid and monocytoid cells, by the infiltration of interfollicular and parafollicular parts of interstitium, as well as by the invasion of clusters of neoplastic lymphoid cells of the glandular epithelium, forming the pathognomic lymphoepithelial MALT limphoma lesions. CASE REPORT: In this paper we presented the two female patients, 59 and 75 years of age, with MALT lymphomas, associated with Miculicz's and Sjögren's syndromes. The paper also underlined rather many-month-long, indolent clinical course, evalution of both tumors, massive in size, as well as two-sided localization in the case of the Miculicz's syndrome. After the subtotal parotidectomy, using conservation of nerve facialis, the tissue blocks were fixed in 10% formaldehyde. The paraffine sections were stained by routine histochemical and an immunohistochemical method by using monoclonal antibodies for both B-cell and T-cell lymphomas, due to the verification of lymphoepithelial lesions. The MALT lymphoma diagnosis was based on the histological criteria and confirmed by an immunohistochemical method. After the surgical therapy accompanied by chemotherapy, the patients were controlled at regular intervals, and residual MALT lymphoma did not appear. CONCLUSION: MALT lymphoma is a rare tumor of the salivary glands, with the most frequent localization in the parotide gland. It had a slow clinical course, without metastases in both patients. The diagnosis was made pathohistologically and confirmed immunohistochemically. The surgical therapy was accompained by adjuvant chemotherapy.
