ABSTRACT The management of locally advanced esophageal cancer is controversial. Treatment options include neoadjuvant chemotherapy or chemoradiation therapy (CRT) followed by definitive surgery or definitive chemoradiation. A single center experience was reviewed to determine the oncologic outcomes of these 3 approaches.
We retrospectively reviewed records of 100 patients with adenocarcinoma and squamous cell carcinoma of the esophagus of which 22 patients received neoadjuvant chemotherapy, 49 patients received neoadjuvant CRT, and 18 patients received definitive CRT. The majority of patients underwent minimally invasive esophagectomy (74%). The mean follow-up was 34 months (median, 22 mo; range, 1 to 180 mo).
Median survival of the entire group was 22.9 months [95% confidence interval (CI) 19.3-30.4]. The 2-year and 5-year overall survival rates were 47.9% and 23.2%, respectively. Median survival of patients who received neoadjuvant chemotherapy, neoadjuvant CRT, and definitive CRT was 31.9 (95% CI 21.2-51.5), 28.7 (95% CI 20.2-40.7), and 8.9 (95% CI 5.7-14.4) months, respectively. Patients who received neoadjuvant CRT were more likely to have pathologic complete response (pCR) (20%) compared with patients who received neoadjuvant chemotherapy alone (0%; P=0.04). The 2-year and 5-year overall survival rates of patients with pCR were 75% and 50%, respectively.
There was no survival benefit or differences in failure pattern seen among the 3 treatment approaches in this series. However, patients who received neoadjuvant CRT were more likely to have pCR and these patients showed a trend toward improved survival.

    ABSTRACT: Despite well-established surgical approaches, the prognosis for patients with squamous cell carcinoma of the esophagus remains dismal. To assess the benefit of adjuvant chemotherapy and radiation therapy (CRT), a randomized trial with and without sequential preoperative CRT was undertaken; CRT combined 20 Gy and two courses of 5-FU and cisplatin. Patients were included on the basis of the following criteria: squamous cell carcinoma of the esophagus, younger than 70 years of age, World Health Organization status below 2, estimated survival time greater than 3 months, and no previous treatment for the cancer. Patients were not included if they had experienced a loss in body weight greater than 15% or had tracheoesophageal fistula, metastases, or uncontrollable infection. Eighty-six patients thus fulfilled the criteria for inclusion (41 CRT, 45 non-CRT). The groups were well-matched for age, sex, tumor location, size, and grade. Operative mortality was 8.5% and 7%, respectively, for each group with a 27-day hospital stay for both groups. Long-term survival was not significantly different, with 47% of both groups alive at 1 year. The authors concluded that this neoadjuvant treatment did not change operative mortality or survival time for patients with squamous cell carcinoma of the esophagus.

    ABSTRACT: Uncontrolled studies suggest that a combination of chemotherapy and radiotherapy improves the survival of patients with esophageal adenocarcinoma. We conducted a prospective, randomized trial comparing surgery alone with combined chemotherapy, radiotherapy, and surgery. Patients assigned to multimodal therapy received two courses of chemotherapy in weeks 1 and 6 (fluorouracil, 15 mg per kilogram of body weight daily for five days, and cisplatin, 75 mg per square meter of body-surface area on day 7) and a course of radiotherapy (40 Gy, administered in 15 fractions over a three-week period, beginning concurrently with the first course of chemotherapy), followed by surgery. The patients assigned to surgery had no preoperative therapy. Of the 58 patients assigned to multimodal therapy and the 55 assigned to surgery, 10 and 1, respectively, were withdrawn for protocol violations. At the time of surgery, 23 of 55 patients (42 percent) treated with preoperative multimodal therapy who could be evaluated had positive nodes or metastases, as compared with 45 of the 55 patients (82 percent) who underwent surgery alone (P<0.001). Thirteen of the 52 patients (25 percent) who underwent surgery after multimodal therapy had complete responses as determined pathologically. The median survival of patients assigned to multimodal therapy was 16 months, as compared with 11 months for those assigned to surgery alone (P=0.01). At one, two, and three years, 52, 37, and 32 percent, respectively, of patients assigned to multimodal therapy were alive, as compared with 44, 26, and 6 percent of those assigned to surgery, with the survival advantage favoring multimodal therapy reaching significance at three years (P=0.01). Multimodal treatment is superior to surgery alone for patients with resectable adenocarcinoma of the esophagus.

    ABSTRACT: In the United States, the incidence of esophageal adenocarcinoma has risen faster than any other malignancy in recent years, and now represents the most common histologic type of esophageal cancer observed in major institutions. The precise etiology of this malignancy, and the epidermiologic variables responsible for its dramatically rising incidence, remains obscure. Elucidation of the molecular biology of malignant transformation in Barrett's esophagus may improve the management of patients with advanced esophageal adenocarcinomas. Furthermore, appreciation of the molecular events associated with esophageal adenocarcinomas. Furthermore, appreciation of the molecular events associated with esophageal adenocarcinogenesis may facilitate early detection of occult carcinomas, and enable therapeutic interventions designed to prevent these otherwise highly lethal neoplasms.
