Summary
Squamous cell carcinoma of the maxillary sinus prognosis is significantly impacted by T stage and neoadjuvant chemotherapy (NAC) response. Advanced T stages and poor NAC response correlate with worse survival and organ preservation outcomes.
Area of Science:
- Oncology
- Head and Neck Surgery
- Medical Imaging
Context:
- Squamous cell carcinoma (SCC) of the maxillary sinus is a rare malignancy.
- Treatment and prognostic factors for advanced maxillary sinus SCC require further elucidation.
- Retrospective analysis of untreated cases treated between 1981-1998 at Keio University Hospital.
Purpose:
- To identify significant prognostic factors for survival and organ preservation in maxillary sinus SCC.
- To evaluate the impact of T stage and neoadjuvant chemotherapy (NAC) on patient outcomes.
- To determine the predictive value of NAC response for prognosis.
Summary:
- A retrospective study of 60 untreated maxillary sinus SCC cases (Stage III/IV: 88.3%) revealed T stage as a significant independent prognostic factor.
- Neoadjuvant chemotherapy (NAC) and its response were also significant independent factors for survival and organ preservation.
- Patients achieving complete or partial response to NAC demonstrated significantly better survival and organ preservation compared to non-responders.
Impact:
- T stage classification and NAC response are crucial for predicting survival and guiding treatment strategies in maxillary sinus SCC.
- Positive NAC response correlates with improved outcomes, suggesting its utility in treatment planning.
- Intensive treatment may be warranted for T4 cases with no response to NAC to improve organ preservation and survival.
