RESUMEN
PURPOSE: To investigate whether hepatic hilar and celiac plexus nerve blocks provide safe and effective analgesia to patients undergoing doxorubicin-eluting embolics transarterial chemoembolization (DEE-TACE) for hepatocellular carcinoma. MATERIALS AND METHODS: In this prospective, randomized trial, 92 patients undergoing DEE-TACE for hepatocellular carcinoma were enrolled. The control group received standard intraprocedural local anesthetic, intra-arterial lidocaine, and intravenous analgesia; the study group underwent additional hepatic hilar and celiac plexus nerve blocks. Intra-arterial lidocaine, intravenous and oral narcotic and antiemetic requirements after the procedure, pain, patient satisfaction, adverse events, and hospital stay were compared. RESULTS: The nerve block group reported less pain during and after the procedure at days 1 and 7 (P < .001), although differences resolved by week 2. The control group received more intra-arterial lidocaine (P < .001) and required approximately double the amount of narcotic analgesia during and after the procedure, extending to 3 weeks after the procedure (P < .001), as well as less antiemetics (P < .001). No differences in adverse events, hospital stay, and overall patient satisfaction were noted. CONCLUSIONS: Hepatic hilar and celiac plexus nerve blocks before procedures can result in lower pain during and after procedures in patients undergoing DEE-TACE. Furthermore, nerve blocks result in lower opioid consumption and opioid-related complications for 3 weeks following procedures.

BACKGROUND: No chemotherapeutic agents have been standardised for transarterial chemoembolisation (TACE). In particular, doxorubicin has no defined optimal dosage in TACE procedures. We compared low versus currently used dose of doxorubicin for TACE in patients with hepatocellular carcinoma (HCC) in terms of severity of post-embolisation syndrome (PES) and overall survival (OS). METHODS: From October 2014 to March 2018, we enrolled patients with primary HCC scheduled for TACE. Patients were randomised to receive 50 mg (group A) or 100 mg (group B) of doxorubicin. Outcomes were the rate of patients with PES; free-time-to-PES; changes in laboratory results; tumour response at 1, 3, and 6 months after TACE; and overall survival. RESULTS: Twenty-eight patients (24 males, 4 females) were enrolled, aged 58.9 ± 6.8 years (mean ± standard deviation). Fifteen of them palliated with 50 mg (group A) and 13 with 100 mg (group B) of doxorubicin for a total of 68 TACE procedures (of 28 patients who had repeated TACE procedures). Visual analogue scale (VAS) and duration of pain were significantly differently lower in group A than in group B (p < 0.001). The median duration of fever was shorter in group A than in group B (p = 0.003). No significant differences between both groups were observed for tumour response to TACE and OS. The doxorubicin dose was significantly correlated with duration of pain, fever, and VAS score. CONCLUSION: A lower dose of doxorubicin (50 mg) was associated with fewer PES symptoms compared with 100 mg, without effects on tumour response nor OS.

OBJECTIVE: To determine the diagnostic accuracy of WB-MRI and 18F-FDG PET/CT in detecting infiltration pattern, disease activity, and response to treatment in patients with multiple myeloma (MM). MATERIALS AND METHODS: Fifty-six patients with confirmed MM were included in the present study for pre-treatment evaluation. Among these individuals, 22 patients were available for the post-treatment evaluation of response to therapy. All patients were imaged with both WB-MRI and 18F-FDG PET/CT. All radiographic findings of infiltration pattern, disease activity, and response to therapy were compared. The diagnostic performance of both modalities was estimated using bone marrow aspirate and biopsy as the reference test. RESULTS: For detection of active myelomatous tissue at diagnosis, WB-MRI achieved higher sensitivity (94%) than 18F-FDG PET/CT (75%) (p = 0.0039), whereas both modalities achieved the same specificity (80%). For detection of residual myelomatous tissue after treatment, 18F-FDG PET/CT achieved higher specificity (86%) than WB-MRI (43%) (p = 0.0081), whereas both modalities achieved the same sensitivity (75%). CONCLUSION: WB-MRI is more sensitive than 18F-FDG PET/CT in the diagnosis of MM before treatment; however, 18F-FDG PET/CT is more specific than WB-MRI in detecting residual involvement in treated patients.
