Radical sublobar resection for lung cancer

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonology

Background:

• Sublobar resection (segmentectomy or wedge resection) is historically reserved for patients with early-stage lung cancer and poor lung function.
• Concerns regarding higher local recurrence rates and poorer prognosis after sublobar resection compared to lobectomy persist.
• Despite increased early-stage lung cancer detection, sublobar resection remains underutilized.

Purpose of the Study:

• To review and compare surgical outcomes of sublobar resection versus lobectomy for lung cancer from existing literature.
• To evaluate the potential of sublobar resection as a primary treatment for select early-stage lung cancer patients.

Main Methods:

• Literature review and synthesis of studies comparing sublobar resection and lobectomy for lung cancer.
• Analysis of surgical outcomes, including local recurrence and prognosis, in selected patient cohorts.

Main Results:

• Evidence suggests promising outcomes for sublobar resection in carefully selected patients.
• Radical sublobar resection is indicated as an alternative for clinical T1N0 lung cancer ≤ 2 cm, even in low-risk individuals.

Conclusions:

• Sublobar resection should be considered a valid alternative to lobectomy for specific early-stage lung cancers.
• The findings support the initiation of new randomized controlled trials to redefine lung cancer surgical standards in the era of early detection.
