Key result
A surgical interval of ≤3 months between contralateral repeated pulmonary resections for lung cancer was associated with greater postoperative morbidity (P=0.029).
Why the study?
Does a surgical interval of ≤3 months increase 30-day postoperative complications compared to >3 months in patients undergoing contralateral repeated pulmonary resection for lung cancer?

p-value: p=.029
A surgical interval of ≤3 months between contralateral repeated pulmonary resections for lung cancer is associated with increased 30-day postoperative morbidity.
A ≤3-month interval was associated with higher morbidity after contralateral re-resection; leaves open whether delaying surgery improves outcomes in selected patients.
Background: With improved survival after initial surgery, repeated pulmonary resections are increasingly performed. However, the clinical effect of the interval between operations remains unclear. Methods: This study retrospectively analyzed data from patients who underwent only contralateral repeated pulmonary resection for lung cancer at a single institution between 2002 and 2024, assessing 30-day postoperative complications. Surgical interval was categorized as ≤3 months and >3 months. Multivariable logistic regression was employed to identify risk factors for morbidity. Results: = .029). Conclusions: Contralateral repeated pulmonary resection is feasible, but a ≤3-month surgical interval is associated with greater postoperative morbidity. The surgical interval should be considered an important factor in operative planning.

Kadomatsu et al. (2026) conducted a cohort in Lung cancer. Surgical interval ≤3 months vs. Surgical interval >3 months was evaluated on 30-day postoperative complications (p=.029). A surgical interval of ≤3 months between contralateral repeated pulmonary resections for lung cancer was associated with greater postoperative morbidity (P=0.029).
