Salvage surgery and microsurgical reconstruction for recurrence of skull base osteosarcoma after carbon ion radiotherapy.

Kohyama K, Yamada K, Sugiura H, Hyodo I, Ozawa T, Hasegawa Y, Kato H, Kamei Y - Nagoya J Med Sci (2015)

Bottom Line: As the patient developed no postoperative wound complications, she was able to initiate adjuvant chemotherapy early.Although the affected field may be limited, its high potency may severely damage adjacent normal tissue and lead to serious postoperative complications.Despite these concerns, satisfactory results were achieved in this case.

ABSTRACT
Carbon ion radiotherapy has recently emerged as an alternative choice of treatment for malignant tumors of the head and neck. However, it is still in the infant stages and its influence on subsequent salvage surgery remains unclear. Here we report the case of a 43-year-old woman who underwent salvage surgery for left frontal bone osteosarcoma recurrence following carbon ion radiotherapy. Tumor resection was performed with a wide margin including the tissue considered to have been damaged by carbon ion radiotherapy. The dural defect was reconstructed using a fascia lata graft and pedicled galeal pericranial flap. The soft tissue defect was reconstructed using an anterolateral thigh flap anastomosed to the ipsilateral neck interposed by the radial forearm flap. As the patient developed no postoperative wound complications, she was able to initiate adjuvant chemotherapy early. Carbon ion radiotherapy is useful for its focused distribution and strong biological effects. Although the affected field may be limited, its high potency may severely damage adjacent normal tissue and lead to serious postoperative complications. Despite these concerns, satisfactory results were achieved in this case.

fig5: Two years postoperatively, the wound healed and the postoperative course was uneventful.

Mentions: The wound healed and the postoperative course was uneventful. Histopathological examination of the resected specimen revealed increased dysplastic spindle cells, leading to a histological diagnosis of osteoblastic osteosarcoma. The degree of reaction to carbon ion radiotherapy, such as fibrosis, was comparatively low. Systemic adjuvant chemotherapy with ifosfamide, carboplatin, and etoposide was administered for 4 months. The patient survived and has remained well for 2 years postoperatively (Figure 5).
