Case report: a young woman with advanced esophageal cancer showing pathological complete response to neoadjuvant chemotherapy (CDDP, 5-FU and ADM)

A 32-year-old woman was admitted to our hospital with dysphagia. An upper gastrointestinal series revealed Borrmann type 2 esophageal cancer in the lower thoracic esophagus. Because direct invasion of the thoracic aorta was suspected, FAP therapy (CDDP, 5-FU and ADM) was given as neoadjuvant chemotherapy. After completion of two courses, her dysphagia resolved and the tumor shrank by over 90%, so radical surgery was performed. No lesions were found when the resected specimen was examined macroscopically. The only histological change was hyperplasia of collagen fibers in the submucosa, lamina propria and adventitia of the esophagus. No cancer cells and no metastases to the lymph nodes were observed. Because the tumor had completely disappeared, the histological effect of chemotherapy was classified as grade 3, i.e., pathological complete response (PCR). The response to FAP therapy was excellent and no serious adverse events occurred. Therefore, this is one of the treatments that should be actively applied in patients who have advanced esophageal cancer with suspected lymph node metastasis and invasion of other organs.
