Trial summary

Many studies suggested that selective lymph node sampling was acceptable for specific non-small cell lung cancer (NSCLC). This study aimed to evaluate the acceptability of omitting of lymphadenectomy for selected NSCLC. Read more about this study

About this study

Many studies suggested that selective lymph node sampling was acceptable for specific non-small cell lung cancer (NSCLC). This study aimed to evaluate the acceptability of omitting of lymphadenectomy for selected NSCLC.

Patients with small-sized (≤2 cm) NSCLC who underwent surgical resection between 2009 and 2022 were retrospectively screened.

Many studies suggested that selective lymph node sampling was acceptable for specific non-small cell lung cancer (NSCLC). This study aimed to evaluate the acceptability of omitting of lymphadenectomy for selected NSCLC.

Patients with small-sized (≤2 cm) NSCLC who underwent surgical resection between 2009 and 2022 were retrospectively screened. The characteristics of patients with nodal metastasis were demonstrated. For selected patients, the perioperative and long-term outcomes of patients with and without lymphadenectomy were compared. Log-rank test and Cox regression analysis were adopted for prognostic evaluation.

A total of 2713 NSCLC patients were enrolled, and 75 of them (2.76%) had nodal involvement. None of patients with pure ground glass opacity (0/945) had nodal metastasis, while 14 patients with part-solid (14/1260, 1.11%) and 61 patients with solid nodules (61/508, 12.01%) had nodal involvement. Patients with nodal metastasis had a minimum solid size of 6 mm. NSCLC with solid components < 6 mm (n=1588) had no nodal metastasis. Of them, 339 patients underwent sublobar resection without lymphadenectomy (SRN0), 1056 subjects received sublobar resection with lymphadenectomy (SRN1), and 190 patients received lobectomy plus lymphadenectomy (LRN1). Patients with SRN0 had a shorter operating time, less volume of drainage, a lower incidence of chylothorax (0 vs. 0.6% vs. 2.1%, P=0.012) and air leakage, as well as a shorter postoperative hospitalization (3 vs. 4 vs. 4 days, P<0.001) than those with SRN1 or LRN1. During a median follow-up of 61 months, no patient with SRN0 was dead or tumor recurrent. The 5-year recurrence-free survival was 100%, 99.2% and 98.5% for patients with SRN0, SRN1 and LRN1, respectively (P=0.370).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall survival (OS)

    OS was defined from the surgical date to the date of death or the date of the last follow-up. defined from the surgical date to the date of death or the date of the last follow-up.

    Measured: OS was defined from the surgical date to the date of death or the date of the last follow-up, whichever came first, assessed up to 14 years.

Questions about this trial

What is this clinical trial studying?

An observational study of Non-small Cell Lung Cancer, run by Liang Chen at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (OS) (time frame: OS was defined from the surgical date to the date of death or the date of the last follow-up, whichever came first, assessed up to 14 years.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2024.
