Adequate primary surgery for mandibular sarcoma is crucial. Radiographic analysis showed inadequate resections led to higher recurrence and mortality rates, emphasizing the need for thorough preoperative evaluation.

Area of Science:

  • Oncology
  • Radiology
  • Surgical Pathology

Background:

  • Mandibular sarcomas are rare but aggressive tumors.
  • Surgical resection is the primary treatment modality.
  • Assessing the radicality of surgery is vital for patient outcomes.

Purpose of the Study:

  • To evaluate the relationship between the radicality of primary surgical procedures and recurrence rates in mandibular sarcoma.
  • To identify radiological indicators of inadequate surgical resection.
  • To determine the impact of preoperative radiological assessment on patient prognosis.

Main Methods:

  • Retrospective analysis of pre- and postoperative radiographs from 11 mandibular sarcoma cases.
  • Radiological assessment of surgical margins and completeness of resection.

  • Correlation of radiological findings with clinical outcomes, including recurrence and mortality.

    • Main Results:

    • Seven out of 11 resections were deemed inadequate based on radiological details.
    • Inadequate primary surgery was associated with a high rate of recurrence (7/7 patients).
    • Adequate primary resection resulted in significantly lower recurrence rates (1/3 patients).

    Conclusions:

    • Radiological findings like mandibular canal widening and lamina dura disappearance are often missed.
    • Thorough preoperative radiological examination is essential for planning radical primary surgery.
    • Improved surgical radicality can decrease recurrence and mortality in mandibular sarcoma patients.
