This study on paranasal sinus cancer found that multimodality therapy, including radiation and surgery, offers the best survival rates. Preoperative radiotherapy is preferred for advanced lesions, improving outcomes.

Area of Science:

  • Oncology
  • Otorhinolaryngology
  • Radiology

Background:

  • Paranasal sinus cancers are rare but aggressive malignancies.
  • Early diagnosis and accurate staging are critical for effective treatment.
  • Traditional diagnostic methods like Caldwell-Luc were insufficient for advanced staging.

Purpose of the Study:

  • To analyze treatment outcomes for paranasal sinus cancer.
  • To evaluate the role of imaging in diagnosis and staging.
  • To determine optimal therapeutic strategies, including radiotherapy timing.

Main Methods:

  • Retrospective analysis of 60 paranasal sinus cancer cases (1970-1985).
  • Utilized computed tomography (CT), magnetic resonance imaging (MRI), and endoscopic sinus examination for diagnosis and staging.

  • Assessed outcomes of multimodality therapy (radiation, surgery, chemotherapy).

    • Main Results:

    • 46 maxillary and 14 ethmoid sinus tumors identified.
    • CT and MRI improved early diagnosis and staging accuracy.
    • 5-year survival rate was 49%; advanced lesions (T3/T4) showed higher recurrence at primary sites.
    • Preoperative radiotherapy increased globe salvage rates.

    Conclusions:

    • Multimodality therapy, especially with radiotherapy and aggressive surgery, improves survival for advanced paranasal sinus cancer.
    • Preoperative radiotherapy is favored for advanced lesions; postoperative for early lesions.
    • Accurate staging with advanced imaging is crucial for treatment planning.
