[A case of effective urgent irradiation therapy for metastatic spine tumor].
A 74-year-old man noticed weakness in bilateral lower limbs 2 months prior to admission. The weakness had rapidly progressed and he could not stand by himself on admission. All thoracic vertebral bodies showed mosaic pattern on T 2 weighted-image. At Th 10 and Th 11, two enhanced masses compressed spinal cord posteriorly. Basal-serum tumor markers, such as LDH, ALP, total-acid phosphatase and prostatic acid phosphatase were elevated, metastatic spine tumor from prostatic carcinoma was suspected. Biopsy specimen from its prostate revealed low differentiated adenocarcinoma. Because sphincter dysfunction progressed rapidly after admission, we started 3 Gy/day irradiation within 24 hr from its appearance targeting both Th 10 to L 1 vertebral bodies and the prostate in total 30 Gy. The clinical symptoms started to resolve immediately, and the disappearance completely within 7 months. This case illustrated that urgent irradiation was effective for broad metastatic spinal tumor with rapidly progressive neurological deficits.
