Abstract
Background: Oral cancer is a malignancy on the lip or oral cavity. Because 90% of cancers in the oral cavity area histologically originated in the squamous cells, they are traditionally defined as oral squamous cell carcinoma (OSCC). OSCC is the 17th most common type of cancer worldwide, based on the International Agency for Research on Cancer (IARC).
Purpose: This study was conducted to analyze the characteristic features of oral squamous cell carcinoma in patients who came to the Oral and Maxillofacial Surgery Department of Hasan Sadikin Hospital from 2016-to 2020.
Methods: This research is a retrospective observational study by taking patients' medical records at the Oral and Maxillofacial Surgery Department of Hasan Sadikin Hospital from 2016 - to 2020 and data from histopathological examination results as confirmation.
Results: During 2016 - 2020, there were 124 patients with OSCC, with several male patients (50.8%) more than the female patient (49.2%) and more common in the age group over 50 years. There was an increasing total of patients per year: 13 patients in 2016; 14 patients in 2017; 22 patients in 2018, 31 patients in 2019, and 44 patients in 2020. The tumours were located on the tongue (58.1%), buccal mucosa (33.1%), gingiva (7.3%), lip (0.8%) and palate (0.8%). Most histopathologic examinations were well-differentiated (53.8%), moderately differentiated (33.6%), and poorly differentiated (12.6%) squamous cell carcinoma.
Conclusion: Over the last 5 years, the number of oral squamous cell carcinoma patients in the Oral and Maxillofacial Surgery Department of Dr Hasan Sadikin hospital has increased. It is more common in men, with an age range above 50. The major histopathology result was well-differentiated squamous cell carcinoma, most of which were located on the tongue.
