Abstract: Objective: To evaluate tumor responses to neoadjuvant therapy, according to the histopathological findings of surgical specimens of patients operated and treated for squamous cell carcinoma of the middle third and distal esophagus. Methods: We conducted a retrospective nonrandomized study including 97 patients distributed as follows: Group I - 81 (83.5%) underwent neoadjuvant radiation therapy, and group II - 16 (16.5%) underwent neoadjuvant radiotherapy and chemotherapy. A third group of 26 patients undergoing esophagectomy alone was used for comparison of postoperative complications. The characteristics of each patient (age, gender and race), tumor site, staging, and histological evaluation of treatment modalities were reviewed and analyzed. Tumor response to neoadjuvant therapy was evaluated by histopathology of the specimen. Results: There was no statistically significant differences regarding race, gender, age, staging and postoperative complications in patients in the three groups. Patients undergoing radiotherapy and neoadjuvant chemotherapy showed more satisfactory tumor reduction, with improved local efficacy when compared to the group only submitted to neoadjuvant radiotherapy. Conclusion: The study suggests that radiotherapy combined with chemotherapy was more efficient in reducing tumor site when compared to the group treated with radiotherapy. In addition, neoadjuvant therapy did not increase the postoperative complications when compared to patients undergoing surgery alone.
