Predicting initial recurrence pattern of esophageal cancer after neoadjuvant chemotherapy.
OBJECTIVE
No report has reviewed which clinicopathological factors including 3-field dissection and the response to neoadjuvant chemotherapy can predict the recurrence pattern of an esophageal carcinoma. The aim of this study was to reveal clinicopathological predictors for the initial recurrence pattern of a thoracic esophageal carcinoma.


METHODS
Sixteen parameters derived from 98 patients who underwent a curative esophagectomy with neoadjuvant chemotherapy for a squamous cell carcinoma of the thoracic esophagus were examined using univariate and multivariate logistic regression analyses.


RESULTS
Thirty-seven (37.8%) of the 98 patients had recurrences (hematogenous; 16, lymphatic; 13, others; 8). Univariate analyses revealed that the completion of 3-field dissection was the only factor for suppressing the lymphatic recurrence (P = 0.009; odds ratio: 0.2). Multivariate analyses showed that the number of positive nodes was a significant predictor for recurrence including all modalities (P = 0.02; odds ratio: 1.2) and both the number of positive nodes (P = 0.04; odds ratio: 1.1) and the poor response to neoadjuvant chemotherapy (P = 0.02; odds ratio: 6.9) were significant predictors for the hematogenous recurrence.


CONCLUSIONS
The number of positive nodes and the response to neoadjuvant chemotherapy could predict the hematogenous recurrence of esophageal carcinoma.
