2018年8月27日 · In the article that accompanies this editorial, Wang and colleagues 1 report on the prognostic impact of dissecting the station 4L mediastinal lymph node (LN) in left-sided lung cancer. Using propensity score weighting, two retrospective patient groups who received surgery between 2005 and 2009 were compared: one with 4L dissection (n = 139 ...

Recently, some studies have assessed the clinical significance of 4L lymph node dissection (4L LND) in left lung cancer and found that station 4L metastasis was not rare and that 4L LND may provide survival benefits (7–12). However, whether 4L LND should be resected remains unclear and controversial because most guidelines have no detailed ...

2018年8月27日 · To investigate the prognostic impact of 4L lymph node (LN) dissection in left lung cancer and to analyze the relative risk factors for 4L LN metastasis. We retrospectively collected data from 657 patients with primary left lung cancer who underwent surgical pulmonary resection from January 2005 to December 2009.

2018年10月10日 · Purpose: To investigate the prognostic impact of 4L lymph node (LN) dissection in left lung cancer and to analyze the relative risk factors for 4L LN metastasis. Patients and methods: We retrospectively collected data from 657 patients with primary left lung cancer who underwent surgical pulmonary resection from January 2005 to December 2009.

Mediastinal lymph node (LN) dissection during lung resection is essential for accurate staging. Station 4L dissection is anatomically difficult. Therefore, care should be taken to avoid complications. We investigated the importance of mediastinal LN ...

The effect of 4L lymph node dissection on the prognosis of left lung cancer is currently controversial. Therefore, a meta-analysis was conducted to compare the difference in prognosis between the dissection group and the non-dissection group, and assess the independent risk factors for 4L lymphatic metastasis.

The prognostic value of 4L lymph node dissection (4L-LND) continues to be controversial. We conducted this systematic review and meta-analysis to evaluate the prognosis of 4L-LND in operable non-small-cell lung cancer (NSCLC) patients. We systematically searched studies from PubMed, Embase, and the …

2021年11月2日 · Despite #4L nodes not being an independent prognostic factor in lung cancer, the percentage of nodal metastases notably increases above pT2a grade and is comparable to the percentage of #5 and #7 metastasis. Therefore, lymphadenectomy in advanced stages of cancer could benefit from resections of the …

2023年11月8日 · Studies investigating the prognostic value of 4L-LND and non-4L-LND in NSCLC survival were included. Data for analysis mainly comprised postoperative complications, overall survival (OS), and disease-free survival (DFS). The Q-test and I 2 …

Currently, surgery is still the most effective treatment for early-stage non-small cell lung cancer (NSCLC) in operable patients. The standard recommended procedure consists in a pulmonary resection that includes the tumor and a lymphadenectomy of the …
