Preoperative Chemotherapy

An intergroup trial (NCT00525785) randomly assigned 440 patients with local and operable esophageal cancer of any cell type to three cycles of preoperative 5-FU and cisplatin followed by surgery and two additional cycles of chemotherapy versus surgery alone.[31][Level of evidence A1]

After a median follow-up of 55 months, there were no significant differences in median survival between the chemotherapy-plus-surgery group (14.9 months) and the surgery-alone group (16.1 months). The median 2-year survival rate was 35% in the chemotherapy-plus-surgery group and 37% in the surgery-alone group.

The addition of chemotherapy did not increase the morbidity associated with surgery.

The Medical Research Council Oesophageal Cancer Working Party randomly assigned 802 patients with resectable esophageal cancer, also of any cell type, to two cycles of preoperative 5-FU and cisplatin followed by surgery versus surgery alone.[28][Level of evidence A1]The interpretation of the results from the intergroup and preoperative chemotherapy trials is challenging because T or N staging was not reported, and prerandomization and radiation could be offered at the discretion of the treating oncologist.

At a median follow-up of 37 months, median survival was significantly improved in the preoperative chemotherapy arm (16.8 months vs. 13.3 months with surgery alone; 95% CI), as was the 2-year OS rate (43% in the preoperative chemotherapy arm and 34% in the surgery-alone arm; 95% CI).

The Japanese Clinical Oncology Group randomly assigned 330 patients with clinical stage II or III, excluding T4, squamous cell carcinomas to receive either two cycles of preoperative cisplatin and 5-FU followed by surgery or surgery followed by postoperative chemotherapy of the same regimen. A planned interim analysis was conducted after patient accrual. Although the primary end point of PFS was not met, there was a significant benefit in OS among patients treated with preoperative chemotherapy (P = .01). As a result of these findings, the Data and Safety Monitoring Committee recommended early closure of the study.[29][Level of evidence A3]

With a median follow-up of 61 months, the 5-year OS rate was 55% among patients treated with preoperative chemotherapy, compared with 43% among patients treated with postoperative chemotherapy (P = .04). However, there was no significant difference between groups with respect to PFS (5-year PFS rate, 39% vs. 44%; P = .22).

Additionally, there were no significant differences between the two groups with respect to postoperative complications or treatment-related toxicities.

The Fédération Nationale des Centres de Lutte contre le Cancer and the FFCD randomly assigned 224 patients with resectable adenocarcinoma of the lower esophagus, gastroesophageal junction, or stomach to receive either perioperative chemotherapy and surgery (n = 113) or surgery alone (n = 111). Chemotherapy consisted of two or three preoperative cycles of intravenous (IV) cisplatin (100 mg/m2) on day 1 and continuous IV infusion of 5-FU (800 mg/m2) for 5 consecutive days (day 1–5) every 28 days, and three or four postoperative cycles of the same regimen.[30][Level of evidence A1]

Perioperative chemotherapy was associated with an improved 5-year OS rate (38% vs. 24%; HR, 0.69; P = .02).

Grade 3 and 4 toxicity occurred in 38% of patients treated with perioperative chemotherapy, but there was no increase in postoperative morbidity.

The Preoperative Chemotherapy or Radiochemotherapy in Esophago-gastric Adenocarcinoma Trial (POET) sought to evaluate the additional benefit of radiation therapy to preoperative chemotherapy. Patients were randomly assigned to receive either induction chemotherapy (15 weeks) followed by surgery or chemotherapy (12 weeks) followed by chemoradiation therapy (3 weeks) and surgery.[32][Level of evidence A1]

The study was closed early because of poor accrual. In total, 126 patients were randomly assigned.

Preoperative radiation therapy yielded 3-year survival rates of 27% to 47% (log-rank P = .07). The postoperative mortality rate was nonsignificantly increased in the chemoradiation therapy group (10.2% vs. 3.8%; P = .26).
