Summary

Sublobar resection offers comparable oncologic outcomes to lobectomy for select early-stage non-small cell lung cancer patients. Achieving adequate surgical margins and thorough lymph node assessment are crucial for successful outcomes.

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Pulmonology

Background:

  • Early-stage non-small cell lung cancer (NSCLC) treatment typically involves lobectomy.
  • Sublobar resection is an alternative for specific patient groups.
  • Optimizing sublobar resection techniques is essential for comparable oncologic outcomes.

Purpose of the Study:

  • To define the criteria and techniques for successful sublobar resection in early-stage NSCLC.
  • To establish guidelines for lymph node sampling and margin assessment during sublobar resection.
  • To outline management strategies for intraoperative and postoperative nodal findings.

Main Methods:

  • Review of oncologic outcomes comparing sublobar resection and lobectomy in early-stage NSCLC.
  • Analysis of surgical techniques, including margin assessment (≥2 cm or > tumor diameter).

  • Evaluation of lymph node sampling protocols (station-based, ≥3 mediastinal, ≥1 intrapulmonary/hilar).

    • Main Results:

    • Sublobar resection demonstrates noninferior oncologic outcomes compared to lobectomy in selected early-stage NSCLC patients.
    • Adequate surgical margins and comprehensive lymph node dissection are critical.
    • Intraoperative frozen section analysis guides conversion to lobectomy if nodal metastasis is present.

    Conclusions:

    • Sublobar resection is a viable option for early-stage NSCLC when specific surgical criteria are met.
    • Meticulous surgical technique, including margin control and lymphadenectomy, is paramount.
    • Adjuvant therapy is indicated for patients with occult nodal disease discovered post-resection.
