The clinical features and prognostic factors of hepatocellular carcinoma patients with spinal metastasis.
OBJECTIVE
Hepatocellular carcinoma is the most common malignancy in Taiwan, and spinal metastasis is a serious complication in cancer patients. In this study, we aimed to delineate the clinical features, evaluate the radiotherapy response and analyse the prognostic features in hepatocellular carcinoma subjects with spinal metastasis.


METHODS
From 1981 to 1997, 102 patients with spinal metastasis were enrolled, taken from the 5887 documented hepatocellular carcinoma patients treated at Taipei Veterans General Hospital. All the clinical and laboratory data were recorded, including: age; gender; liver biochemistry; tumour characteristics; Child-Pugh's score; performance status; number and location of vertebral metastasis; motor capacity; neurological symptoms and signs; response to radiotherapy of the spinal lesion; and survival. Prognostic factors in hepatocellular carcinoma patients with spinal metastasis were analysed using Cox's regression model.


RESULTS
The most common symptoms in hepatocellular carcinoma patients with spinal metastasis were lower back pain (74.5%), thoracic numbness (52.9%) and lower limb weakness (51.0%). Of the 102 patients, 84 received palliative radiotherapy using 3000 cGy for spinal lesions. Of these 84 patients, 32.1% showed a complete response, 26.2% a partial response and 41.7% a non-response to the radiotherapy. Multivariate Cox's regression analysis revealed that responsive radiotherapy (complete response + partial response) and good performance status (score <or= 2) were significant positive prognostic factors for survival in hepatocellular carcinoma patients with spinal metastasis.


CONCLUSIONS
Responsive radiotherapy can improve a hepatocellular carcinoma patient's quality of life by ameliorating the neurological condition and relieving pain, and can prolong survival in hepatocellular carcinoma patients with spinal metastasis.
