Abstract

The present study aimed to investigate the recurrence pattern of thoracic esophageal cancer (TEC) following radical surgery for guiding postoperative radiotherapy (PRT). Patterns of recurrence were analyzed in patients with recurrence for the first time after radical surgery at the First Affiliated Hospital of Anhui Medical University (Anhui, China) from January 2012 to December 2015. A total of 244 patients were reviewed in the study. The mean recurrence time for patients with PRT was >1 month longer than that for patients without PRT. The lymphatic, anastomotic and hematological recurrence ratios were 87.9 vs. 69.2%, 4.0 vs. 11.5% and 8.0 vs. 17.2%, respectively for patients without and with PRT. The most common recurrence regions were staion1 and station 2‑4 (30.0 vs. 36.5% and 37.2% vs. 23.1%, respectively, for patients without and with PRT). The lymphatic recurrence of upper TEC was almost in station1 and station 2‑4 (infield). The middle and lower TEC also had a high probability of lymphatic recurrence in station 1 and station 2‑4 (totally 76.3 vs. 57.6% and 61.9 vs. 61.1%, respectively). The recurrence ratio significantly decreased in station 2‑4 (infield) for middle TEC patients with PRT compared with patients without PRT (P=0.03), while no significant differences in the lymphatic recurrence ratios were observed in other regions (P>0.05). The differences of recurrence ratios in station 7, station 8 and celiac regions (infield) for lower TEC patients without and with PRT also demonstrated no statistical significance (P>0.05). The results of the present study indicated that the lower neck, supraclavicular regions and upper mediastinal regions (station 1, 2 and 4) should be included in the clinic target volume (CTV) for PRT, while lower mediastinal regions, celiac regions and anastomotic may not be included in CTV.
