Abstract
BACKGROUND:
The optimal postoperative surveillance protocol after esophagectomy for patients with esophageal cancer has still not been established. We investigated the risk factors for recurrence of esophageal cancer to devise an appropriate surveillance protocol. We focused on the appearance and worsening of symptoms to determine if additional imaging examinations should be performed.
STUDY DESIGN:
We enrolled 416 patients with esophageal and esophagogastric junctional cancer who had undergone thoracoscopic esophagectomy at Tokai University Hospital. Outpatient visits for the patients are usually scheduled at least 4 times per year with CT imaging and blood biochemical examination. We evaluated the time to recurrence after esophagectomy, especially the correlation of this parameter with the appearance and worsening of symptoms during the postoperative outpatient follow-up.
RESULTS:
Of the 416 patients, recurrence occurred in 127 patients (30.5%). The median time to recurrence was 6 months after esophagectomy; recurrence occurred within 24 months in 112 patients (88%), and 51 of these patients (40%) developed some new symptom(s) (symptomatic group) before the diagnosis of recurrence. The number of patients who developed recurrence within 6 months was significantly higher in the symptomatic group compared with that in the asymptomatic group (66.7% vs 46.0%, p = 0.02). The overall survival in the symptomatic group was significantly shorter than that in the asymptomatic group (p < 0.001).
CONCLUSIONS:
We advocate an effective surveillance protocol depending on the appearance and worsening of symptoms to diagnose recurrence of esophageal cancer; we recommend routine imaging examinations every 6 months and clinical outpatient follow-up at even shorter intervals for the first 24 months after esophagectomy.
