Abstract
Background: The aim of this study was a comprehensive analysis of the incidence of different salivary gland pathologies in the adult population of Poland. Methods: A retrospective analysis of salivary gland pathologies diagnosed in Poland in 2010–2019 based on the National Health Fund (NHF) database was performed. Non-neoplastic diseases, and benign and malignant lesions were identified using ICD-10 codes. Demographic characteristics, incidence rates, and the number of inpatient and outpatient medical services were analyzed. Results: Salivary gland pathologies were diagnosed in 230,589 patients over 10 years (85.5% were non-neoplastic lesions, 11.53% benign and 2.93% malignant neoplasms). Incidence rate for all pathologies was 59.94/100,000. The mean incidence for malignant neoplasms was 1.78, and decreasing trend was observed over the analyzed period. Contrarily, for benign neoplasms (mean incidence—6.91), an increase in numbers was noted annually. The incidence for non-malignant lesions was quite stable (mean: 51.25) over the time. The highest number of medical services per patient concerned malignant neoplasms (on average, two hospital stays, and eleven outpatient consultations). Conclusions: An increase of benign salivary gland tumors, and a decrease of malignant neoplasms was observed during the studied period. The number of medical services related to salivary gland pathologies increased during the period under study.
Highlights
The percentages amounted to 85.5% for non-neoplastic lesions, 11.53% for benign tumors, and 2.93% for malignant neoplasms
The incidence rates and demographic characteristics of the studied group are presented in Figure 1 and Table 2
The analysis revealed an increasing trend in the incidence of benign salivary gland neoplasm, and a decrease in malignant pathologies over the recent decade in the Polish population
Summary
A number of inflammatory and reactive lesions of the salivary glands may mimic neoplastic disease, so in most patients, imaging diagnosis, including ultrasonography and magnetic resonance imaging or computed tomography, must be routinely performed. Non-neoplastic diseases, and benign and malignant lesions were identified using ICD-10 codes. Results: Salivary gland pathologies were diagnosed in 230,589 patients over 10 years (85.5% were non-neoplastic lesions, 11.53% benign and 2.93% malignant neoplasms). The mean incidence for malignant neoplasms was 1.78, and decreasing trend was observed over the analyzed period. For benign neoplasms (mean incidence—6.91), an increase in numbers was noted annually. The highest number of medical services per patient concerned malignant neoplasms (on average, two hospital stays, and eleven outpatient consultations). Conclusions: An increase of benign salivary gland tumors, and a decrease of malignant neoplasms was observed during the studied period
