European Radiology: Relationship between preoperative needle biopsy technique and ipsilateral pleural recurrence in stage I lung cancer

 The detection rate of lung nodules has increased significantly due to the popularity of low-dose computed tomography (CT) screening for early -stage lung cancer .
When nodules are detected on CT images, management principles depend on the risk of malignancy, and pathological diagnosis of nodules at risk for lung cancer is critical to guide appropriate treatment .
Percutaneous transthoracic needle lung biopsy (PTNB) is widely used in the pathological diagnosis of lung cancer and provides high accuracy in diagnosing lung cancer .
The most common complication of PTNB is pneumothorax, followed by hemoptysis and pulmonary hemorrhage .

.

In patients who underwent curative resection of early-stage lung cancer after preoperative PTNB, the frequency of pleural recurrence of ipsilateral lung cancer was higher than that in patients who did not receive PTNB, which is a concern

Pleural recurrence is a rare, potentially long-term complication of PTNB

A study published in the journal European Radiology examines whether a specific PTNB technique reduces the risk of ipsilateral pleural recurrence after curative resection of stage I lung cancer, paving the way for further widespread use of the technique .
 

This study retrospectively enrolled 415 consecutive patients with stage I lung cancer who underwent preoperative PTNB and curative resection from 2009 to 2016, and collected detailed information, including the clinical, PTNB technique, radiology, and pathology of lung cancer.

The total follow-up period after PTNB was 62.

In conclusion, after adjusting for tumor and patient characteristics using PSM, no specific PTNB technique can reduce ipsilateral pleural metastases after PTNB in ​​stage I lung cancer
