[A clinical study on superior sulcus tumors]

Area of Science:

• Oncology
• Thoracic Surgery

Context:

• Superior sulcus tumors represent a small but significant subset of lung cancer.
• Understanding the characteristics and outcomes of these tumors is crucial for effective treatment planning.

Purpose:

• To investigate the clinical characteristics, diagnostic methods, and survival outcomes of patients with superior sulcus tumors.
• To explore the relationship between treatment modalities (staging, irradiation, surgery) and patient survival.

Summary:

• The study included 29 patients (26 male, 3 female) with superior sulcus tumors, accounting for 2.1% of lung cancer cases. The average age was 66.2 years, with a high prevalence of smoking history (93.1%). Histologically, adenocarcinoma was most common (10 cases), followed by squamous cell carcinoma (9 cases). Over half the patients (51.7%) presented with Stage IV disease, and 27.6% had extrathoracic symptoms. Pancoast syndrome was observed in 31.0% of cases. Diagnosis was primarily achieved through transbronchial biopsy (51.7%) and echoguided needle biopsy (34.5%). Tumors were frequently located in posterior lesions (44.8%). Twenty patients received radiation therapy.
• Clinical staging, irradiation, and surgical treatment were identified as key factors influencing survival length. The median survival time observed in this cohort was 7 months.

Impact:

• Provides insights into the demographics, histology, and clinical presentation of superior sulcus tumors.
• Highlights the importance of diagnostic accuracy and timely intervention in managing these challenging lung cancers.
• Emphasizes the prognostic significance of treatment strategies and clinical stage on survival, informing future therapeutic approaches.
