Summary
Radical surgical resection offers improved survival for lung cancer patients with mediastinal lymph node metastases (N2). Complete resection significantly increases 3-year survival rates compared to incomplete procedures.
Area of Science:
- Thoracic Surgery
- Oncology
- Pulmonary Medicine
Background:
- Lung cancer with mediastinal lymph node metastases (N2) presents a significant therapeutic challenge.
- Surgical management of N2 lung cancer remains a critical area of research for improving patient outcomes.
Purpose of the Study:
- To evaluate the impact of surgical resection extent on survival in patients with N2 lung cancer.
- To analyze prognostic factors influencing survival in this patient cohort.
Main Methods:
- Retrospective analysis of 28 patients with N2 lung cancer undergoing surgery between 1978 and 1981.
- Categorization of patients based on surgical intervention: exploration, incomplete resection, and complete resection.
- Postoperative treatment with MACC + BCG (Multimodal Adjuvant Chemotherapy and Cyclophosphamide, Methotrexate, Vincristine, Procarbazine + Bacillus Calmette-Guérin).
Main Results:
- A resectability rate of 86% was achieved, with 19 patients undergoing complete resection.
- Patients with complete resection showed significantly better survival: 78% at 1 year, 61% at 2 years, and 47% at 3 years.
- Adenocarcinoma histology correlated with a higher 3-year survival rate (60%) compared to squamous cell carcinoma (37%). No 30-day mortality was observed.
Conclusions:
- Radical surgical resection is a crucial component in the treatment of N2 lung cancer.
- Prognosis is influenced by factors within the TNM staging system and histological subtype.
- Adjuvant therapies, including radiotherapy and multichemotherapy, are recommended following radical surgery.
