     Abstract ABSTRACT Background: Oral squamous cell carcinoma (OSCC) is the most common cancer in the oral cavity. This malignant tumor may locally destroy the surrounding tissue, such as the gingiva and jaw bones, and later spread to some regional lymph nodes and other distant organs. Bone invasion by OSCC has major effects on tumor staging, outcome and quality of life. Various types of radiograph have been used as important diagnostic tools to detect tumor invasion both in the bone and soft tissue, including cervical lymph nodes. More than 50% of head and neck squamous cell carcinoma patients present with regional lymph node involvement. Lymph node metastasis is associated with poor survival and is one of the most important factors for selecting appropriate treatment. In Thailand, although many advanced radiographic techniques are available in some referral medical centers, panoramic radiography is still the most commonly used technique for screening bone invasion because of its many advantages. However, there are still some questions whether the detection of bone invasion by the tumor using panoramic radiography can have a benefit of predicting cervical lymph node metastasis or not. Objectives: This study aimed to preliminarily investigate the association of bone invasion by tumor and cervical lymph node metastasis by comparing patient pre-operative panoramic radiographs and histopathologic evidence of cervical lymph node metastasis. Methods: Panoramic radiographs of seventy-five patients who had OSCC treated by surgical resection and modified or radical neck dissection were retrieved and analyzed by using Fisher’s exact test. P<0.05 was considered statistically significant. All the cervical lymph nodes taken from the modified or radical neck dissection were histologically examined to provide information of cervical lymph node metastasis. Results: The Fisher’s exact test of bone invasion and cervical lymph node metastasis was 0.812. No statistically significant correlation was observed. Conclusion: We concluded that panoramic radiography should be used only as an initial imaging for screening bone invasion in OSCC because of the lower sensitivity compared with other techniques. The result of our study also demonstrated that there was no statistically significant correlation between bone invasion and cervical lymph node metastasis. Therefore, more advanced imaging techniques are needed as an adjunct tool for detecting bone invasion and cervical lymph node metastasis of oral cancer.
