A new preoperative immunochemotherapy for the treatment of locally advanced esophageal cancer.
A promising preoperative immunochemotherapy regimen for locally advanced esophageal cancer is herein described. A 67-year-old man suffering from severe dysphagia was diagnosed with unresectable esophageal cancer at initial examination because of a tumor of 11 cm in length and suspicion of trachea invasion. Neoadjuvant immunochemotherapy was undertaken for the down-staging. Interleukin-2 (IL-2) (3.5 x 10(5) Japan reference units), nedaplatin (7 mg/m2) and 5-FU (300 mg/m2) were administered intravenously daily for 5 days a week for three weeks. The gross findings of a barium esophagogram and esophagoscopy revealed significant tumor regression in both size and shape. The patient underwent an esophagectomy through a laparotomy followed by a right thoracotomy. The surgical specimens were serially sectioned and examined microscopically. All of the surgical margins were clear (upper and lower margins as well as the adventitia), and there was no evidence of lymph node metastasis. The surgical specimen revealed neoplastic squamous ghost cells surrounding significant lymphocyte infiltration. This appears to be a unique feature of this particular neoadjuvant immunochemotherapy.
