Preoperative Chemoradiotherapy for Esophageal Cancer

The combination of chemotherapy, fluorouracil and cisplatin, and radiation has improved outcome for patients with esophageal cancer. A randomized controlled trial confirmed a long-term survival benefit when this chemotherapy was added to radiotherapy for squamous cell carcinoma, but the approach has not been definitively assessed in patients with adenocarcinoma. Preoperative chemoradiotherapy has been tested in numerous phase II studies and underpowered or flawed phase III studies. Nevertheless, collectively, the evidence strongly suggests that preoperative chemoradiotherapy improves outcome, and thus, this strategy has become a standard treatment option. Attempts to improve outcome by intensifying conventional cytotoxic drugs or increasing the radiation dose have not been successful. Camptothecin and taxane-based regimens combined with radiation have altered the toxicity profile, but substantial improvement in survival outcomes has yet to be demonstrated. Future improvements will likely require the incorporation of targeted agents that add minimally to existing toxicity, the use of molecular predictors of response to individualize selection of the chemotherapeutic regimen, and early identification of responders such that therapy might be altered dynamically.

Nutrition is important for patients with esophageal cancer because dysphagia can be exacerbated by chemoradiotherapy. Some centers suggest routine enteral tube placement (TF) to facilitate nutrition. This investigation was to evaluate the use of TF access for patients undergoing multi-modality therapy for esophageal carcinoma. This retrospective study analyzed 113 patients who underwent esophagectomy and 97 patients who underwent definition chemoradiotherapy for esophageal cancer between 2001 and 2013. Throughout this time period, a strategy for selective tube placement was used. Nutrition was assessed through absolute lymphocyte counts, protein, and albumin levels. A total of 28 (30%) patients during preoperative chemoradiotherapy and 31 (32%) of those undergoing definitive chemoradiation received TFs. There were 16 Dobhoff tubes, 28 gastrostomy tubes, and 15 jejunostomies. Tubes were maintained an average of 3.9 months with 20 (34%) of these patients reporting tube-related complications. At the time of surgery, there was no statistical difference in any of the nutritional assessments between those patients who received TF and those who did not. Both groups experienced similar total postoperative complication rates (64% vs 65%) and similar median length of hospital stay (12 to 13 days). Chemoradiotherapy resulted in decreased nutritional parameters; however, there was no difference in the degree of reduction between those who underwent TF and those who did not. The data show that routine placement of enteral access is not necessary for esophageal carcinoma. In fact, the risks of placing enteral access may outweigh the benefits. Administration of TF should be restricted to select patients during chemoradiotherapy or before esophagectomy.
