RESUMEN
It is unknown whether Ivor Lewis (IL) or McKeown (McK) esophagectomy is preferred in patients with potentially curable esophageal or gastro-esophageal junction (GEJ) cancer. Patients with mid- and distal esophageal and GEJ cancer without distant metastases who underwent IL or McK esophagectomy in the Netherlands between 2015 and 2017, were selected from the Netherlands Cancer Registry. Patients were propensity score matched for sex, age, American Society of Anesthesiologist classification, comorbidity, tumor type, tumor location, clinical stage, neoadjuvant treatment and year of diagnosis. The primary outcome was a 3-year relative survival (RS). Secondary outcome parameters were number of lymph nodes examined, number of positive lymph nodes, radical resection rate, tumor regression grade, post-operative complications and mortality. A total of 1627 patients who underwent IL (n = 1094) or McK (n = 533) esophagectomy were included. Patient and tumor characteristics were balanced after propensity score matching, leaving 658 patients to be compared. The 3-year RS was 54% after IL and 50% after McK esophagectomy, P = 0.140. The median number of lymph nodes examined, median number of positive lymph nodes, radical resection rate and tumor regression grade were comparable between both groups. Recurrent laryngeal nerve palsy (2 vs. 5%, P = 0.006) occurred less frequently after IL esophagectomy. No differences were observed in post-operative anastomotic leakage rate, pulmonary complication rate and mortality rates. There was no statistically significant difference in the 3-year RS between IL and McK esophagectomy. Based on these results, both IL and McK esophagectomy can be performed in patients with mid to distal esophageal and GEJ cancer.
