[Successful Multidisciplinary Treatment Accomplished by Collaboration of Multiple Clinical Departments for Synchronous Quadruple Cancer].

A 60-year-old man consulted a clinic complains of sore throat. Squamous cell carcinoma of the hypopharynx and adenocarcinoma of the stomach were pointed out and he was refered to our hospital. As a result of detailed systemic examination, squamous cell carcinoma of the esophagus and squamous cell carcinoma of the right lung were also pointed out, which led to a diagnosis of synchronous quadruple cancer. On the basis of discussions among multiple clinical departments, systemic chemotherapy with cisplatin(CDDP), fluorouracil (5-FU) and docetaxel(DTX) was preceded locolegional therapies. After that, complete thoracoscopic right lower lobectomy and then a laparoscopic distal gastrectomy was performed. Radiation therapy was applied for hypopharyngeal cancer. Finally, endoscopic submucosal dissection for esophageal cancer was performed. Twenty months have passed since the last treatment, the patient is alive with a relapse-free condition.
