A 67-year-old man was diagnosed to have sigmoid colon cancer with peritonitis carcinomatosa. The cancer was surgically resected, and he thereafter underwent chemotherapy with mFOLFOX6+bevacizumab. He complained of gingival swelling throughout treatment and osteonecrosis of the jaw was noted. The bevacizumab therapy was therefore discontinued and the necrotic tissue removed. No recurrent necrosis has occurred. The addition of bevacizumab to the FOLFOX or FOLFIRI chemotherapy regimens has been shown to improve the survival rate and response rate in colorectal cancer. Osteonecrosis of the jaw is a rare toxicity of bevacizumab. Bevacizumab might compromise the microvessel integrity in the jaw, which thus may lead to bone necrosis. Osteonecrosis of the jaw in this case recovered after the discontinuation of bevacizumab and the removal of the necrotic tissue. The pathogenesis and treatment of osteonecrosis have not been elucidated.

A 49-year-old woman was admitted to our hospital because of epigastralgia and abdominal distension. She was diagnosed as advanced colon cancer with para-aortic and common iliac lymph node metastases, without liver and lung metastasis. Extended right hemicolectomy was performed to remove symptoms of stenosis. Bevacizumab (BV) (5 mg/kg) + mFOLFOX6 was performed as the initial postoperative chemotherapy. The tumor marker CEA, CA19-9 decreased, and reduction in the size of distant lymph node metastasis was confirmed, which obtained PR. In July 2009, computed tomography revealed the right pulmonary hilar lymph node metastases and progressive disease was confirmed; therefore, cetuximab and FOLFIRI combination therapy was initiated. However, in October 2009, bilateral inguinal lymph node metastases was seen; therefore we changed chemotherapy to BV (10 mg/kg) and FOLFIRI. Although the abdominal lymph node was decreased slightly after 2 months, chemotherapy was changed to BV (10 mg/kg) and mFOLFOX6 since the inguinal lymph node had enlarged. Skin metastases appeared, and there was no change in the inguinal lymph node and abdominal lymph node. She was deceased due to peritonitis carcinomatosis; however, her survival time exceeded 30 months. There was a possibility that long-term survival could be obtained by increasing the quantity of BV and re-administering it in second-line chemotherapy after PD in BV + FOLFOX first-line chemotherapy.
