Summary
Predicting oral cancer invasion into the mandible pre-operatively is challenging. This study validates clinical, radiological, and scintigraphic features against histology to improve surgical decisions for mandible preservation or sacrifice.
Area of Science:
- Oncology
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Pre-operative assessment of oral cancer invasion into the mandible is often unreliable, leading to individualized surgical decisions.
- The choice between preserving or sacrificing the mandible in oral cancer cases is complex due to prediction difficulties.
Purpose of the Study:
- To evaluate the reliability of pre-operative clinical, radiological, and scintigraphic parameters in assessing mandibular invasion by oral cancer.
- To correlate these pre-operative findings with detailed bone histology in a cohort of oral cancer patients.
Main Methods:
- Analysis of 44 oral cancer cases.
- Comparison of clinical examination findings, radiological imaging (CT scans), and scintigraphy with histopathological examination of the mandible.
Main Results:
- Clinical, radiological, and scintigraphic features were compared against histological confirmation of tumour invasion.
- The study identified specific parameters that reliably predict or rule out mandibular involvement.
Conclusions:
- Superior marginal resections are effective for oral cancer lesions near, but not invading, the mandible.
- These techniques are also suitable for superficial lesions involving the mandible where CT and bone scans show no tumour invasion.
