Bronchogenic carcinoma associated with upper aerodigestive cancers

Area of Science:

• Oncology
• Pulmonology
• Otorhinolaryngology

Background:

• Patients diagnosed with upper airway cancers exhibit a significant risk of developing secondary lung malignancies.
• The co-occurrence of upper airway and lung cancers, termed multiple airway cancers, presents unique diagnostic and therapeutic challenges.

Purpose of the Study:

• To investigate the incidence, characteristics, and outcomes of patients with multiple airway cancers.
• To compare the clinical presentation and prognosis of multiple airway cancers with previous reports.

Main Methods:

• Retrospective analysis of 1,450 patients with upper airway cancers, identifying 61 cases of multiple airway cancers.
• Evaluation of diagnostic intervals, cancer cell types, patient demographics, staging, symptomatology, and survival data.

Main Results:

• The overall incidence of multiple airway cancers was 4.1%, with a higher incidence of adenocarcinoma (24%) and a notable proportion of women (26%) compared to historical data.
• Median survival was significantly shorter for symptomatic patients (6 months) and those with Stage III lung cancer (6 months).
• Management of post-thoracotomy patients with prior upper airway cancer treatment was challenging due to airway compromise.

Conclusions:

• Patients with upper airway cancer are at high risk for lung cancer, irrespective of cell type.
• Synchronous or metachronous airway cancers necessitate a strategic treatment approach, prioritizing the more life-threatening malignancy.
• Optimal treatment sequencing, favoring lung cancer intervention before upper airway cancer treatment when feasible, can mitigate management complexities and improve outcomes.
