Changes in the surgical treatment of pulmonary metastases during the last 12 years

INTRODUCTION In our retrospective study, we examined changes in the histological results and types of metastatectomies of pulmonary metastases during the last 12 years, in two 5-year periods. AIM AND METHOD There were 55 patients in the first group (2006-2010), 54.5% of the patients were male (n = 30), 45.5% were female (n = 25), the mean age was 57.9 years (24-80). The second group (2014-2018) consisted of 115 patients, with 60% male (n = 69) and 40% female (n = 46), the mean age was 62.2 years (26-82). RESULTS During the first period, the primary tumor was found in the rectum 19.3% (n = 11), colon 17.5% (n = 10), or kidney 14% (n = 8), while during the second period, the primary tumor was in the colon in 23.1% (n = 31), in the rectum in 15.7% (n = 21), or in the kidney in 9% (n = 12). The following types of surgeries were performed: atypical resection: 38.6% (n = 22) and 46.3% (n = 62); lobectomy in 31.6% (n = 18) and 26.9% (n = 36); pulmonectomy in 10.5% (n = 6) and 1.5% (n = 2); segmentectomy in 7% (n = 4) and 9.7% (n = 13); and bilobectomy in 1.8% (n = 1) and 0.7% (n = 1) in the first and second group, respectively. The ratio of video-assisted thoracic surgery (VATS) was 5.3% (n = 3) during the first period, and this ratio increased to 64.9% (n = 87) during the second period. The mean disease-free survival between the surgery of the primary tumor and the removal of the pulmonary metastasis was 45.2 months (0-144) during the first period and 33.8 months (0-180) during the second period. The median survival was 39 months in the first period, and it increased to 59 months in the second group. The mean 5-year survival was 41% in both groups. CONCLUSION During the last 12 years, there was a more than two-fold increase in the number of patients requiring surgery due to pulmonary metastases, and the ratio of VATS metastasectomy increased significantly as well (5.3% vs. 64.9%). No significant difference was found in the ratio of the types of the primary tumors. The median survival was slightly better in the second group. Orv Hetil; 161(29): 1215-1220.
