Pdf Summary

A study conducted at the National Cancer Center Hospital in Japan aimed to determine the impact of tumor location on surgical margin in sublobar resection, specifically segmentectomy and wedge resection. The researchers analyzed data from 630 patients who underwent sublobar resection for stage I non-small cell lung cancer between April 2016 and June 2020.<br /><br />The study found that segmentectomy achieved a higher proportion of sufficient surgical margin compared to wedge resection, regardless of tumor location. Even in tumors classified as "easy" according to the Lewis classification, wedge resection did not provide an adequate surgical margin. On the other hand, segmentectomy had a larger surgical margin in both easy and difficult locations.<br /><br />Recurrence-free survival was also better in patients who underwent segmentectomy compared to wedge resection. The hazard ratio for recurrence was lower in segmentectomy patients, indicating a decreased risk of cancer recurrence. <br /><br />Based on these findings, the researchers concluded that segmentectomy is preferable to wedge resection due to its higher likelihood of achieving an adequate surgical margin and better recurrence-free survival, even for tumors that could be easily removed with wedge resection. This study highlights the importance of considering tumor location when making surgical decisions for sublobar resection in lung cancer patients.
