<sec><h3>Background</h3>
<p>Oral squamous cell carcinoma (OSCC) is the sixth most common malignancy in Asia. Most patients in Cipto Mangunkusumo Hospital have been diagnosed with an advanced stage. There had not been any survival study for OSCC in Indonesia. This study aimed to investigate the survival rate and prognostic factors of OSCC in Cipto Mangunkusumo Hospital.</p>
</sec>
<sec><h3>Methods</h3>
<p>A retrospective cohort study was conducted on OSCC patients diagnosed and treated in Cipto Mangunkusumo Hospital from 2014 to 2018. Data regarding age, gender, site of the primary lesion, clinical stage of the disease, tumor differentiation, invasion, and surgical margins were collected. The main outcomes measured were overall survival (OS) and disease-specific survival (DSS). The predictors of survival were then determined.</p>

<sec><h3>Result</h3>
<p>169 patients were included. The majority of patients were male (51.5%) and above 50 years old (55.6%). The most prevalent tumor site was the tongue (72.8%) followed by buccal mucosa (13%).

Background
Oral squamous cell carcinoma (OSCC) is the sixth most common malignancy in Asia. Most patients in Cipto Mangunkusumo Hospital have been diagnosed with an advanced stage. There had not been any survival study for OSCC in Indonesia. This study aimed to investigate the survival rate and prognostic factors of OSCC in Cipto Mangunkusumo Hospital.

Methods
A retrospective cohort study was conducted on OSCC patients diagnosed and treated in Cipto Mangunkusumo Hospital from 2014 to 2018. Data regarding age, gender, site of the primary lesion, clinical stage of the disease, tumor differentiation, invasion, and surgical margins were collected. The main outcomes measured were overall survival (OS) and disease-specific survival (DSS). The predictors of survival were then determined.

Result
169 patients were included. The majority of patients were male (51.5%) and above 50 years old (55.6%). The most prevalent tumor site was the tongue (72.8%) followed by buccal mucosa (13%). The majority (82.2%) of patients had advanced (clinical stage IV) disease at diagnosis. A smaller majority of patients had a well-differentiated tumor (60.4%) and a low-grade tumor (53.8%). The worst one-year and two-year overall survival rates were found in the stage IV group (53.5% and 37.5%, respectively). The disease-specific survival rate was 66.9%.

Conclusion
The one-year and two-year overall survival rates of OSCC in Cipto Mangunkusumo Hospital were 58.6% and 43.1%. Moreover, clinical stage, tumor size, and lymph node involvement were the most significant prognostic factors for OSCC.
