Summary
Segmental resections offer a viable alternative for early-stage lung cancer, showing survival rates comparable to lobar resections. This approach demonstrates promising overall survival (OS) and disease-free survival (DFS) in patient cohorts.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Pulmonology
Background:
- Segmental anatomical resections are increasingly recognized for their potential benefits in treating early-stage lung cancer.
- Evidence suggests similar overall survival (OS) and disease-free survival (DFS) compared to lobar resections.
Purpose of the Study:
- To evaluate the efficacy and outcomes of segmentectomies for early-stage lung cancer.
- To assess survival rates and complication profiles of patients undergoing segmentectomy.
Main Methods:
- Retrospective analysis of 34 segmentectomies performed between January 2018 and September 2022.
- Exclusion of trauma-related or secondary procedures.
- Data collection on patient demographics, tumor characteristics, surgical approach (VATS, thoracotomy, RATS), and oncological outcomes.
Main Results:
- 29 segmentectomies (85.3%) were for malignancies, primarily primary lung cancer (PLC) (82.8%) including adenocarcinoma and squamous cell carcinoma.
- High R0 resection rate (95.8%) achieved.
- Disease-free survival (DFS) at 5 years was 66.7%, and overall survival (OS) at 5 years was 95%.
Conclusions:
- Segmental resections are a viable option for selected patients with early-stage lung cancer.
- The study supports the use of segmentectomies, showing promising survival outcomes consistent with existing literature.
- Limitations include a small number of preoperative diagnoses and instances of postoperative upstaging.
