説明

Metastatic oral tumors generally carry a poor prognosis. It is therefore important to consider thepatient's quality of life (QOL) when planning treatment of metastatic oral lesions. In this article, we report a caseof transverse colon adenocarcinoma that metastasized to the maxilla and cervical lymph nodes 1 year after colorectomy.<BR>A 64-year-old man underwent surgery for transverse colon adenocarcinoma in January 2005 and received preoperativechemotherapy followed by secondary surgery because metastases to the iliopsoas muscle appeared in May2005. Because the patient's serum tumor marker levels increased again in October 2005 and he had swelling inhis left maxillary gingiva, he visited our hospital in January 2006. At presentation, the carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels were 18.1 and 689.9 ng/ml, respectively. Histologicalexamination of the gingival tumor revealed adenocarcinoma. Because distant metastasis was not detected in additionto the oral and neck lesions, we performed radical surgery of the oral and neck region. After surgery, theserum tumor marker levels of CEA and CA19-9 significantly decreased to 3.9 and 92.5 ng/ml, respectively. Thepatient is presently alive with no postoperative local recurrence or metastasis to other organs as of December 2006.
