[A case of advanced esophageal cancer invaded to the trachea with PCR after preoperative chemoradiotherapy, which relapsed at the time of three years and seven months after resection].

A male in his 40s was diagnosed with type-3 advanced esophageal cancer in the upper thoracic and cervical esophagus, which invaded to the trachea. We administered a low-dose FP combination therapy (5-FU and CDDP) along with 40 Gy radiotherapy. This chemoradiotherapy reduced the esophageal tumor significantly, and then we performed subtotal esophagectomy. Histological examination of the resected specimens revealed no residual cancer cells in the primary lesion or regional lymph nodes. No recurrence had occurred for about three years and seven months after the operation. However, CT revealed that the patient had the signs of recurrence (bone and lung), and finally he died four years and eight months after the operation. Preoperative chemoradiotherapy is potentially effective for advanced esophageal cancer invaded to adjacent organs. Although chemoradiotherapy yielded a complete response in our case( an advanced esophageal cancer patient), a patient follow-up is necessary because a recurrence may occur along the way.
