Segmentectomy for roentgenographically occult bronchogenic squamous cell carcinoma
The Annals of Thoracic Surgery
|April 20, 2001
Summary
Segmentectomy may be a viable surgical option for carefully selected early-stage lung cancers (ROSCCs), offering comparable survival rates to lobectomy with potential lung function benefits. Further research is needed to confirm its clinical advantages.
Area of Science:
- Thoracic Surgery
- Pulmonary Oncology
- Surgical Oncology
Background:
- Roentgenographically occult bronchogenic squamous cell carcinomas (ROSCCs) represent early-stage, central lung cancers.
- Some ROSCCs are unsuitable for less invasive intrabronchial treatments.
- The necessity of lobectomy for ROSCC surgical management remained unclear.
Purpose of the Study:
- To evaluate the efficacy and safety of segmentectomy versus lobectomy for ROSCCs.
- To compare survival rates, postoperative outcomes, and pulmonary function between segmentectomy and lobectomy for ROSCCs.
Main Methods:
- Retrospective analysis of clinicopathologic data from 58 patients who underwent segmentectomy for ROSCCs.
- Comparison of these patients with 98 patients who underwent lobectomy for ROSCCs across 16 institutions.
Main Results:
- Five-year survival rates were high for segmentectomy (96.8% based on cancer deaths, 82.6% overall).
- Segmentectomy showed comparable operative mortality and complication rates to lobectomy.
- Patients undergoing segmentectomy demonstrated improved postoperative lung function (vital capacity and FEV1).
Conclusions:
- Segmentectomy presents a potential alternative surgical approach for select ROSCC patients.
- The findings support segmentectomy as a feasible option, warranting further investigation.
- Prospective studies are recommended to definitively establish the clinical benefits of segmentectomy for ROSCCs.
