ABSTRACT
The patient was a 57-year-old woman. Preclinical examination of malignant lymphoma revealed 0-I sp type of early rectal cancer in the upper rectum, 20 cm from the anal margin. Endoscopic mucosal resection was performed and positive deep margins were pathologically diagnosed. Additional intestinal resection with lymph node dissection was deemed necessary, but ABVD therapy was initiated because the clinical stage of the malignant lymphoma was Stage III b or higher. Two months after detecting elevated CEA, S8 liver metastasis was pointed out, and examination of weakness of the right upper limb revealed nodular, multifocal brain metastasis. After chemotherapy for malignant lymphoma, bevacizumab(BV)plus Xelox therapy was initiated. After administering 4 courses, partial loss of multiple brain metastases and reduction of the liver metastatic lesion were confirmed; therefore, partial resection of the liver via laparoscopy was performed. After surgery, BV plus Xelox therapy was resumed, but since the lower lobular lung metastasis was confirmed after 8 courses, partial resection of the left lower lobe with thoracoscopy was performed. After lung resection, BV plus FOLFIRI therapy was administered, and 12 months after the onset of treatment for brain metastasis, recurrence was not detected.
