Summary
Squamous cell carcinoma of the pinna (SCCP) has a poorer prognosis. Wide margin excision is recommended, with neck dissection for advanced cases, improving survival rates for this rare cancer.
Area of Science:
- Oncology
- Dermatology
- Surgical Oncology
Context:
- Squamous cell carcinoma (SCC) of the pinna, the auricle of the ear, presents unique challenges in diagnosis and treatment.
- SCC of the pinna is often associated with a worse prognosis compared to SCC in other anatomical locations.
- Early and accurate management is crucial for improving patient outcomes.
Purpose:
- To evaluate the treatment outcomes and prognostic factors for squamous cell carcinoma of the pinna.
- To determine optimal surgical and adjuvant treatment strategies for SCC of the pinna.
- To identify predictors of recurrence and survival in patients with SCC of the pinna.
Summary:
- A study of 88 patients treated for SCC of the pinna between 1975 and 1990 found a 5-year survival rate of 95% with curative intent.
- Lymph node metastases were present in 9% of cases pre-treatment. Local tumor control and survival were significantly poorer with neck metastases.
- Recommended first-line treatment is tumor excision with wide margins (5-10 mm); neck dissection with parotidectomy is indicated for specific high-risk features.
Impact:
- Establishes wide margin excision as the primary treatment for SCC of the pinna.
- Provides clear guidelines for the indication of neck dissection and parotidectomy, improving risk stratification.
- Highlights the importance of considering regional lymph node status in treatment planning for better oncological outcomes.
