Summary
Surgical management of malignant parotid tumors in 30 patients showed high primary tumor control. Tailored surgical approaches combined with selective radiotherapy offer effective treatment for these rare cancers.
Area of Science:
- Oncology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Malignant parotid tumors are rare but aggressive neoplasms.
- Surgical intervention is the primary treatment modality.
- Facial nerve involvement and tumor fixation impact prognosis and surgical strategy.
Purpose of the Study:
- To present a series of patients with malignant parotid tumors treated surgically.
- To evaluate the efficacy of different surgical techniques and adjuvant radiotherapy.
- To correlate treatment strategies with outcomes, including recurrence and survival.
Main Methods:
- Retrospective analysis of 30 patients with malignant parotid tumors undergoing surgical treatment.
- Detailed description of surgical procedures, including parotidectomy and facial nerve management.
- Documentation of adjuvant postoperative radiotherapy use and follow-up duration (mean 5.5 years).
Main Results:
- Surgery alone achieved primary tumor control in 15 of 16 patients without adjuvant radiotherapy.
- Postoperative radiotherapy was administered to 14 patients.
- Local recurrence rates were low (1/16 for surgery alone, 1/14 for surgery + radiotherapy); distant metastases occurred in 2 patients (surgery alone) and 1 patient (surgery + radiotherapy).
Conclusions:
- Parotidectomy with facial nerve preservation and selective radiotherapy is effective for mobile, discrete malignant parotid tumors.
- More extensive surgery and adjuvant radiotherapy are indicated for fixed tumors with facial nerve palsy.
- Multidisciplinary management is crucial for optimizing outcomes in malignant parotid tumors.
