RESUMO
BACKGROUND: This retrospective analysis was undertaken to evaluate the efficiency of SIRT with Y-90 microspheres and determined prognostic factors affecting patients with unresectable HCC. METHODS: A total of 97 patients diagnosed with unresectable HCC who underwent SIRT with Y-90 microspheres. Patient survival was assessed using the Kaplan-Meier method, and prognostic factors affecting survival were assessed using log-rank tests and Cox proportional hazards regression. RESULTS: Among the 97 patients (90 males, mean age 60.4 ± 12.3 years) who underwent SIRT, the median clinical follow-up was 16.4 (1.8-62) months. The median overall survival (OS) was 23.9 ± 2.4 months. Tumor response according to the Modified RECIST in patients followed up beyond 6 months included a complete response (CR) to treatment in 12 patients (18.8%), partial response (PR) in 23 (35.8%), stable disease (SD) in 8 (12.5%), and progressive disease (PD) in 21 (32.8%). Factors associated with longer OS included age > 65 years, BCLC stage B, tumor size < 5 cm, tumor burden < 25%, and tumor response (CR/PR). In multivariate analysis, unilobar disease and objective tumor response (CR/PR) were predictors of longer OS. CONCLUSION: SIRT was an effective treatment for unresectable HCC. Unilobar disease before SIRT and tumor response (CR/PR) were positive prognostic factors.

INTRODUCTION: Transarterial hepatic chemoembolization (TACE) has been used to treat unresectable hepatocellular carcinoma and has gained widespread acceptance as a treatment for both primary and secondary hepatic malignancies. CASE REPORT: We report a case of 78-year-old male patient with chronic hepatitis B, diagnosed with HCC. He underwent the second TACE, and right after the procedure, the patient abruptly developed bilateral lower extremities motor weakness and sensory impairment below the T10 dermatome. Spinal magnetic resonance imaging showed T2-weighted scans showed increased intramedullary signal strength at the T1-T12 level. The patient received supportive care, ongoing rehabilitation, and steroid pulse therapy. The motor strength remained unchanged, but the sensory deficiencies practically disappeared. CLINICAL DISCUSSION: The hepatic artery injury or decreased flow at the prior TACE site, which causes collateral recruitment, can explain why spinal cord injury following TACE typically happens after the second or third session. It can occasionally result from accidental embolized spinal branches originating from intercostal or lumbar collateral arteries. In our case, we hypothesize the embolism caused the infarction to the spinal cord travel through the connection between the lateral branches of the right inferior phrenic artery and the intercostal arteries, which supply the spinal cord through the anterior spinal artery. CONCLUSIONS: TACE in rare case can have severe complications. A tailored therapeutic strategy, including consideration of a shunt and selection of the vessels utilized for the Lipiodol infusion prior to TACE, is crucial to achieving an optimal end outcome to avert these significant consequences.
