A recently completed study indicates that patients undergoing a specific type of biopsy before surgery for early-stage Non-Small cell Lung cancer (NSCLC) may face a heightened risk of the disease returning. The findings, released this week, focus on the impact of Percutaneous Transthoracic Needle Biopsy (PTNB) on local-regional recurrence rates.
What is Percutaneous Transthoracic Needle Biopsy?
Percutaneous Transthoracic needle Biopsy, or PTNB, is a diagnostic procedure used to obtain tissue samples from suspicious areas in the lungs. It’s a critical step in determining the type and stage of lung cancer, guiding treatment decisions for early-stage NSCLC. Though, experts have long debated whether the procedure itself could potentially contribute to the spread of cancer cells, even though this risk is generally considered to be minimal.
Study Reveals Increased Recurrence Risk
the retrospective study, encompassing data from over 2,000 patients treated between January 2010 and december 2021, found a substantially higher rate of cancer recurrence in individuals who had a PTNB performed before sublobar resection – a surgical procedure removing only a portion of the lung – for stage I NSCLC.
Specifically, the recurrence rate in the PTNB group was 15.3%, compared to just 5.8% in those who did not undergo the biopsy. This difference was observed in both local-regional recurrence (7.3% vs 2.1%) and distant recurrence rates (8.0% vs 3.7%).
key Findings at a Glance
| Characteristic | PTNB Group (%) | Non-PTNB Group (%) |
|---|---|---|
| Overall Recurrence Rate | 15.3 | 5.8 |
| Local-Regional Recurrence | 7.3 | 2.1 |
| Distant Recurrence | 8.0 | 3.7 |
| 5-Year Freedom From Recurrence | 82.8 | 93.0 |
Furthermore, the study demonstrated a concerning trend in mortality rates. Patients who underwent PTNB experienced a higher risk of death compared to those who did not, even after adjusting for other factors.
Study limitations and Future Directions
Researchers acknowledge that the study possesses certain limitations, including its retrospective nature and reliance on data from a single medical center. This may limit the broad applicability of the findings. Additionally,the study focused on patients with tumors up to 3 centimeters in size,and the optimal surgical approach for larger tumors remains a subject of ongoing investigation.
Did You Know? According to the american cancer Society, Lung cancer remains the leading cause of cancer death in both men and women in the United States, with an estimated 234,580 new cases expected in 2024.
The authors emphasize the need for further, prospective studies to confirm these observations and to fully understand the clinical implications of PTNB in the context of early-stage NSCLC treatment.

Understanding non-Small Cell Lung Cancer
Non-small Cell Lung Cancer, or NSCLC, accounts for approximately 80-85% of all lung cancer diagnoses. Common types include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Early detection and prompt treatment are crucial for improving outcomes in NSCLC, with surgical resection often being the primary treatment option for early-stage disease.
pro Tip: Maintaining a healthy lifestyle, including avoiding smoking and exposure to carcinogens, can significantly reduce your risk of developing lung cancer. Regular screenings are also recommended for individuals at higher risk.
Frequently Asked Questions about Lung Biopsies and Recurrence
- What is a lung biopsy? A lung biopsy is a procedure to remove a small sample of lung tissue for examination under a microscope to help diagnose lung diseases, including cancer.
- What is the role of PTNB in diagnosing lung cancer? PTNB helps determine if a lesion is cancerous and, if so, what type of cancer it is indeed, guiding treatment decisions.
- Does a biopsy increase the risk of cancer spreading? While rare, there is a theoretical risk that a biopsy could cause cancer cells to spread, but this is generally considered vrey low.
- What is stage I NSCLC? Stage I NSCLC is early-stage lung cancer that is localized to the lung and has not spread to nearby lymph nodes.
- What are the treatment options for stage I NSCLC? Treatment options typically include surgical resection, and in some cases, stereotactic body radiation therapy.
- What is sublobar resection? Sublobar resection involves the removal of only a portion of the lung, as opposed to the entire lobe.
- how can I reduce my risk of lung cancer? Avoiding smoking, minimizing exposure to pollutants, and regular screenings can help reduce your risk.
