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.
