C-arm CT guided percutaneous vertebroplasty for pain release in cancer patient with cervical 1 vertebral metastases: A case report.

OBJECTIVE: To evaluate the efficacy and treatment outcome of C-arm CT percutaneous vertebroplasty in the treatment of cervical 1 (C1) vertebral metastases. METHODS: This report recruited a male patient diagnosed with hepatocellular carcinoma and C1 vertebral metastases, who had suffered from severe neck pain symptoms and the analgesic showed little soothing effect. Under the guidance of C-arm CT, an 18G coaxial needle was used to puncture the left lateral mass of C1 vertebral metastases from lateral space between thyroid cartilage and the left carotid sheath, with 2 ml bone cement injected. RESULTS: Postoperative C-arm CT three-dimensional reconstruction scan showed that the bone cement was well filled and distributed in the left lateral mass of C1 vertebral body, and no leakage of bone cement was observed. The neck pain of the patients was significantly relieved one week after the operation. CONCLUSION: Under the guidance of C-arm CT, cement augmentation using percutaneous vertebroplasty in an anterior cervical direction could serve as a safe and effective pain relief approach for patients with C1 vertebral metastases.

Percutaneous microwave ablation and transcatheter arterial chemoembolization for serum tumor markers and prognostics of middle-late primary hepatic carcinoma.

BACKGROUND: Primary hepatic carcinoma (PHC) has an insidious onset and is usually diagnosed in the middle and late stages. Although transcatheter arterial chemoembolization (TACE) is the preferred option for treating middle- and advanced-stage PHC, it has limited efficacy in killing tumor cells and poor long-term efficacy. TACE plus percutaneous microwave coagulation therapy (PMCT) is more effective than interventional therapy alone and can improve survival time. However, there are few reports on the effects of TACE and PMCT on serum marker levels and the prognosis of patients with advanced PHC. AIM: To investigate the effect of PMCT + TACE on serum tumor markers and the prognosis of middle-late PHC. METHODS: This retrospective study included 150 patients with middle-late PHC admitted to Zhongshan People's Hospital between March 2018 and February 2021. Patients were divided into a single group (treated with TACE, n = 75) and a combined group (treated with TACE + PMCT, n = 75). Before and after treatment, the clinical efficacy and serum tumor marker levels [carbohydrate antigen 19-9 (CA19-9), alpha-fetoprotein (AFP), and carcinoembryonic antigen (CEA)] of both groups were observed. The 1-year survival rates and prognostic factors of the two groups were analyzed. RESULTS: The combined group had 21 and 35 cases of complete remission (CR) and partial remission (PR), respectively. The single group had 13 and 25 cases of CR and PR, respectively. After 4 wk of treatment, the serum CA19-9, CEA, and AFP levels in the single and combined groups decreased, with the decrease in the combined group being more significant (P < 0.05). The 1-year survival rate of the combined group (80.00%) was higher than that of the single group (60.00%) (P < 0.05). The average survival time within 1 year in the combined group was 299.38 ± 61.13 d, longer than that in the single group (214.41 ± 72.97 d, P < 0.05). COX analysis revealed that tumor diameter, tumor number, and the treatment method were prognostic factors for patients with middle-late PHC (P < 0.05). CONCLUSION: TACE + PMCT is effective in treating patients with mid-late PHC. It reduces the levels of tumor markers, prolongs survival, and improves prognosis.
