Clinical case of a successful treatment of stage IV esophagal adenocarcinoma

Background. Esophageal adenocarcinoma is often diagnosed at an advanced stage. The overall five-year survival rate of metastatic esophageal adenocarcinoma is less than 15 %. The main treatment strategy is drug therapy. The search for new drugs is still ongoing. Therefore, the assessment of the effectiveness of currently existing options is of great significance. Description of the clinical case. A 45-year-old patient with advanced esophageal cancer with omental, mediastinal and subclavian lymph node metastases received 4 cycles of CF chemotherapy and 3 cycles of DCF + trastuzumab chemotherapy. After 25 cycles of maintenance therapy with trastuzumab, stable disease was observed. There were no significant adverse events associated with the use of trastuzumab. Currently, the patient has no any symptoms of disease. Conclusion. Trastuzumab for the treatment of HER2- overexpressing esophageal cancer was shown to be very effective. The presented clinical case demonstrates not only the feasibility of controlling metastatic disease using targeted therapy, but also maintaining a high level of quality of life.
