Left sleeve lobectomy versus left pneumonectomy for the management of patients with non-small cell lung cancer

Double sleeve resections

Double sleeve lung resections are complex surgical procedures that require specialized surgical expertise and careful patient selection. These procedures allow for the preservation of lung tissue while still achieving complete tumor resection for central tumors. Although initially considered high-risk operations, double sleeve lung resections have become a viable option for central tumors. Recent studies have shown that double sleeve lung resections are associated with lower morbidity and mortality rates than pneumonectomy. Furthermore, double sleeve lung resections may be associated with similar or even better long-term oncological outcomes compared to pneumonectomy, with the added benefit of preserving lung parenchyma and reducing the incidence of postoperative complications.

Parenchymal Sparing Surgery for Lung Cancer: Focus on Pulmonary Artery Reconstruction

Reconstruction of the pulmonary artery (PA) associated with lobectomy for the radical resection of lung cancer has been progressively gaining diffusion in lung cancer surgery as a safe and effective therapeutic option that may allow radical resection when lobectomy is not technically feasible, avoiding pneumonectomy. There are some controversial aspects concerning the intraoperative and perioperative management of a sleeve resection with PA reconstruction that may influence the outcome. In the present article, the authors have analyzed some of the main technical and oncological aspects to take stock of what they have learned from their lung-sparing operations experience over time. PA reconstruction may require prosthetic materials including different options with variable cost. A main concern in vascular reconstructive procedures is avoiding tension on the anastomosis. When PA reconstruction is required, appropriate anticoagulation management is crucial. Results from the main literature data confirm the reliability of lobectomy associated with PA reconstruction in terms of perioperative morbidity and long-term survival. Sleeve lobectomy and PA reconstruction can be performed safely and effectively even after induction therapy.

Clinical characteristics and survival outcomes of patients with pneumonectomies: A population-based study

Background

Prognostic factors in a pneumonectomy (PN) are not yet fully defined. This study sought to analyze and evaluate long-term survival after pneumonectomies (PNs) for patients with non-small cell lung cancer (NSCLC).

Methods

We obtained data from the Surveillance, Epidemiology, and End Results (SEER) database for patients who underwent PNs between 2004 and 2015. Propensity score matching (PSM) analysis and Kaplan–Meier curves were used to estimate overall survival (OS), while univariate and multivariable Cox proportional hazards regression analyses were applied to create a forest plot.

Results

In total, 1,376 patients were grouped according to right/left PNs. Before matching, OS was worse after a right PN [hazard ratio (HR): 1.459; 95% CI 1.254–1.697; P < 0.001] and after matching, survival differences between groups were not significant (HR: 1.060; 95% CI 0.906–1.240; P = 0.465). Regression analysis revealed that age, gender, grade, lymph node dissection, N-stage, and chemotherapy were independent predictors of OS (P < 0.05). Chemotherapy was associated with improved OS (P < 0.001).

Conclusions

Laterality was not a significant prognostic factor for long-term survival after a PN for NSCLC. Chemotherapy was a significant independent predictor of improved OS. Long-term survival and outcomes analyses should be conducted on larger numbers of patients.
