Abstract
Background
This study was performed to clarify the optimal therapeutic strategy for recurrent disease after esophagectomy.
Methods
We investigated the prognosis of 37 patients who developed recurrence among 128 patients who underwent curative thoracoscopic esophagectomy (TE) at Kanazawa University Hospital. The prognostic factors after recurrence were examined by univariate and multivariate analyses.
Results
Of these 37 recurrences, 29 patients underwent local therapy (surgery, 10 patients; surgery followed by radiation, 2 patients; radiation, 17 patients). Radiation includes intensity-modulated radiation therapy, chemoradiation, and simple radiation therapy. Seventeen patients (58.6%) were considered to have undergone successful therapy by disappearance or diminishment of the targeted region without regrowth. Eleven of 17 patients (64.7%) showed repeat recurrence at another site. Multiple local therapy was performed for repeat recurrence or uncontrollable first therapy. Finally, 57 local therapies were performed. Using multimodal local therapy, 37 (64.9%) of 57 recurrences were successfully managed. The 12 patients treated by surgery as the initial therapy showed the most favorable survival. Seventeen patients who underwent successful initial therapy showed better survival than others. Multiple or miscellaneous organ metastasis, abdominal lymphatic recurrence and best supportive care at recurrence were statistically significant negative variables for survival after recurrence. Performance of surgery and successful therapy as the initial recurrence were statistically significant positive variables for survival after recurrence. Multivariate analysis showed that successful therapy at the initial recurrence was the only independent variable for survival after recurrence.
Conclusions
Multimodal local therapy for repeat recurrence after TE contributes to the improvement of survival after recurrence.
