Limited resection for Stage I lung cancer

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Stage I lung cancer management has evolved, with increasing interest in less invasive surgical options.
• Sublobar resection (wedge or segmental) versus lobar resection (lobectomy or bilobectomy) outcomes for early-stage lung cancer require further evaluation.
• Patient co-morbidity influences surgical decision-making in lung cancer treatment.

Purpose of the Study:

• To compare the outcomes of limited resections versus lobar resections for Stage I lung cancer.
• To assess the safety and efficacy of sublobar resections in patients with co-existing cardiac or pulmonary conditions.
• To evaluate the long-term survival and recurrence rates associated with different surgical approaches for early-stage lung cancer.

Main Methods:

• Retrospective analysis of 61 patients undergoing sublobar resection and 411 patients undergoing lobar resection for Stage I lung cancer between 1971-1988.
• Comparison of operative mortality, cancer recurrence rates, and actuarial survival at 5 years between the two groups.
• Subgroup analysis based on pathological T stage (pT1, pT2) and presence of co-morbidities.

Main Results:

• Limited resection group had 0% operative mortality compared to 3% in the lobar resection group.
• Overall 5-year actuarial survival was 55% for limited resection and 49% for lobar resection (not statistically significant).
• In patients with co-morbidity, limited resection showed similar 5-year survival (53% vs 51%) with no peri-operative deaths.

Conclusions:

• Limited resection is a safe and effective option for early-stage lung cancer, offering comparable survival to lobar resection.
• Sublobar resection is particularly beneficial for patients with cardiac or pulmonary co-morbidities, with excellent safety profile.
• Adequate nodal staging is crucial when considering limited resection for early-stage lung cancer management.
