Evaluation of histopathological findings in very old people (≥ 80 years old) in Turkish population

Abstract

Abstract Background The lesions observed in very old populations exhibit a wide spectrum of characteristics. Histopathological evaluation may be necessary for accurate diagnosis in this demographic. There is limited amount of data on the histopathological evaluation of lesions in very old patients. Therefore, the aim of this study was to assess the histopathological features in this population. Methods A total of 5376 pathological samples from very old patients (≥ 80 years old) were analyzed. Clinical and pathological data were retrospectively reviewed. Histopathological diagnoses were categorized into three groups: malignant (invasive) lesions (MLs), benign/inflammatory lesions (BLs), and dysplastic-dysmorphic/non-invasive malignant lesions (DLs). Statistical analyses were conducted on the histopathological data. Pearson’s chi-square test and the Fisher exact test were used to analyze the data, and statistical significance was considered at a p-value of < 0.05. Results The mean age of the patients was 83.6 ± 3.4 years (range: 80–107), with 53% being female. The upper gastrointestinal (GI) tract was the most common site among all materials (28%, n = 1524). Benign/inflammatory lesions (BLs) accounted for the highest proportion of cases (62%, n = 3322) compared to MLs and DLs. BLs were significantly more prevalent in female patients (p < 0.001). MLs were notably more common in biopsies from breast locations (p < 0.001). No patients were diagnosed with DLs in the cytological materials. Conclusions Despite the broad spectrum of lesions observed in very old patients, the majority tend to be benign. While the Coronavirus disease 2019 (COVID-19) pandemic has altered healthcare dynamics, the increased frequency of benign lesions among the very old population, as a result of more frequent healthcare facility visits, is noteworthy. However, dysplastic and malignant lesions remain significant in this population and can profoundly impact patients’ quality of life. This study contributes to our understanding of histopathological diagnoses in the very old population, shedding light on the current approach to managing their pathological specimens.
