Article Synopsis
- OSCC is the most common cancer in males in Sri Lanka, with neck metastasis being a key prognostic factor.
- A study of 187 OSCC patients showed only 6.4% had positive level V lymph nodes after neck dissection.
- It is suggested that routine neck dissection, including level V, may not be necessary, and alternative factors like positivity in levels III and IV should guide treatment decisions.

Article Synopsis
- Oral submucous fibrosis (OSF) is a chronic condition prevalent in South Asia, lacking comprehensive scientific insights into its various aspects.
- The disease's significant concern lies in its potential for carcinogenesis, especially given its high transformation rate compared to other oral disorders.
- A specific patient group showed malignant verrucous growths clinically, but histological tests revealed no invasion, indicating the need for further research into this phenomenon in OSF patients.
Article Synopsis
- The TNM system is the primary method for assessing the clinical outcome of Oral Squamous Cell Carcinoma (OSCC) patients and guides treatment decisions.
- A retrospective study of 430 patients in Sri Lanka revealed that incomplete tumor excision significantly decreased survival, while postoperative radiotherapy improved outcomes, particularly for certain stages.
- Key factors influencing survival included TNM stage, presence of nodal metastasis, and the status of excision margins, with specific surgical options leading to varied survival rates among patients.
