RESUMO

OBJECTIVE: To compare pancreaticoduodenectomy (PD) and total pancreatectomy (TP) with islet autotransplantation (IAT) in patients at high risk of postoperative pancreatic fistula (POPF). BACKGROUND: Criteria to predict the risk of POPF occurrence after PD are available. However, even when a high risk of POPF is predicted, TP is not currently accepted as an alternative to PD, because of its severe consequences on glycaemic control. Combining IAT with TP may mitigate such consequences. METHODS: Randomized, open-label, controlled, bicentric trial (NCT01346098). Candidates for PD at high-risk pancreatic anastomosis (ie, soft pancreas and duct diameter ≤3 mm) were randomly assigned (1:1) to undergo either PD or TP-IAT. The primary endpoint was the incidence of complications within 90 days after surgery. RESULTS: Between 2010 and 2019, 61 patients were assigned to PD (n=31) or TP-IAT (n=30). In the intention-to-treat analysis, morbidity rate was 90·3% after PD and 60% after TP-IAT ( P =0.008). According to complications' severity, PD was associated with an increased risk of grade ≥2 [odds ratio (OR)=7.64 (95% CI: 1.35-43.3), P =0.022], while the OR for grade ≥3 complications was 2.82 (95% CI: 0.86-9.24, P =0.086). After TP-IAT, the postoperative stay was shorter [median: 10.5 vs 16.0 days; P <0.001). No differences were observed in disease-free survival, site of recurrence, disease-specific survival, and overall survival. TP-IAT was associated with a higher risk of diabetes [hazard ratio=9.1 (95% CI: 3.76-21.9), P <0.0001], but most patients maintained good metabolic control and showed sustained C-peptide production over time. CONCLUSIONS: TP-IAT may become the standard treatment in candidates for PD, when a high risk of POPF is predicted.

RESUMO

BACKGROUND: Anatomical resection (AR) is a recommended surgical treatment for hepatocellular carcinoma (HCC), although the conventional procedure (dye injection) for AR is difficult to reproduce.1,2 The tumor-feeding portal pedicle compression technique has been proposed as an easy, reversible, repeatable, and oncologically suitable procedure,3-5 and its only drawback is the sometimes faint discoloration of the compressed area. For enhancing its visibility, indocyanine green (ICG) fluorescence imaging has been introduced. This technique is herein disclosed while performing an anatomical S8 dorsal subsegmentectomy. METHODS: A 66-year-old male was admitted for a 3.7 cm HCC in segment 8 dorsal (S8d) grown in non-alcoholic steatohepatitis. The preoperative liver function was graded as Child-Pugh class A. After adequate liver mobilization, the subsegmental Glissonian pedicle to S8d was identified by intraoperative ultrasound (IOUS) and compressed transparenchymally between the probe and the surgeon's fingertip positioned at the opposed side of the liver. Once IOUS-guided vessel compression had begun, ICG was administered intravenously. The compressed vessel created a non-stained area, which was marked using electrocautery. RESULTS: An anatomical S8d subsegmentectomy using the ICG compression technique was performed. There was no congested area and the right hepatic vein was exposed at the hepatocaval confluence because the resection was conducted in a subsegmental fashion. There was no morbidity and no blood transfusions were necessary. The patient was discharged on day 6 after surgery. CONCLUSIONS: This video shows, for the first time, the finger compression technique successfully implemented by ICG imaging for performing an AR for HCC.

RESUMO

BACKGROUND AND OBJECTIVES: Streptococcus pneumoniae urinary antigen (u-Ag) testing has recently gained attention in the early diagnosis of severe and critical acute respiratory syndrome coronavirus-2/pneumococcal co-infection. The aim of this study is to assess the effectiveness of Streptococcus pneumoniae u-Ag testing in coronavirus disease 2019 (COVID-19) patients, in order to assess whether pneumococcal co-infection is associated with different mortality rate and hospital stay in these patients. MATERIALS AND METHODS: Charts, protocols, mortality, and hospitalization data of a consecutive series of COVID-19 patients admitted to a tertiary hospital in northern Italy during COVID-19 outbreak were retrospectively reviewed. All patients underwent Streptococcus pneumoniae u-Ag testing to detect an underlying pneumococcal co-infection. Covid19+/u-Ag+ and Covid19+/u-Ag- patients were compared in terms of overall survival and length of hospital stay using chi-square test and survival analysis. RESULTS: Out of 575 patients with documented pneumonia, 13% screened positive for the u-Ag test. All u-Ag+ patients underwent treatment with Ceftriaxone and Azithromycin or Levofloxacin. Lopinavir/Ritonavir or Darunavir/Cobicistat were added in 44 patients, and hydroxychloroquine and low-molecular-weight heparin (LMWH) in 47 and 33 patients, respectively. All u-Ag+ patients were hospitalized. Mortality was 15.4% and 25.9% in u-Ag+ and u-Ag- patients, respectively (p = 0.09). Survival analysis showed a better prognosis, albeit not significant, in u-Ag+ patients. Median hospital stay did not differ among groups (10 vs. 9 days, p = 0.71). CONCLUSIONS: The routine use of Streptococcus pneumoniae u-Ag testing helped to better target antibiotic therapy with a final trend of reduction in mortality of u-Ag+ COVID-19 patients having a concomitant pneumococcal infection. Randomized trials on larger cohorts are necessary in order to draw definitive conclusion.

RESUMO

Type II endoleaks are a common complication after endovascular abdominal aortic aneurysm repair, with transarterial embolization using synthetic surgical glue being an established treatment option. We report a case of paraplegia due to spinal cord ischemia after lumbar arteries embolization by Glubran-lipiodol glue for a type II endoleak. Special attention must be given by interventional specialists when applying surgical diluted glues for the treatment of type II endoleaks to avoid distal embolization and subsequent spinal cord ischemia.

RESUMO

BACKGROUND: Liver resection (LR) of colorectal metastases is associated with high recurrence risk. Aggressive local retreatment is advocated, but further recurrences may occur. Poor is known about presentation, treatment, and outcome of iterative recurrences. METHODS: A series of 323 consecutive patients undergoing first LR in the period 2004-2013 was reviewed. Patients with recurrence were included. Any local treatment (surgery, radiofrequency ablation (RFA) and stereotactic body radiation therapy (SBRT)) was analyzed. If first recurrence (1st Rec) was treated, further recurrences and treatments were considered. RESULTS: Overall, 206 (63.8%) patients had 1st Rec; 105 (51.0%) were treated (72 surgery, 19 RFA, 14 SBRT). Among treated patients, 78.1% had 2nd Rec, 74.4% 3rd Rec, 72.2% 4th Rec. Liver involvement progressively decreased (from 81.6 to 30.8%), and pulmonary one increased (from 23.3 to 53.8%). The proportion of treated patients remained stable (1st Rec = 51%, 2nd Rec = 55%, 3rd Rec = 56.3%, 4th Rec = 69.2%): surgery and RFA decreased (from 35.4 to 23.1%; from 9.2 to 0%) and SBRT increased (from 6.8 to 46.2%). Overall, 105 patients received 205 treatments (133 operations in 80 patients). Surgery had the best local disease control: at 2 years 93.4% versus RFA 56.4% (p = 0.0008) and SBRT 74.0% (p = 0.051). In comparison with chemotherapy, recurrence treatment improved survival after 1st Rec (3-year survival 62.9 vs. 13.4%, p < 0.0001), 2nd Rec (61.3 vs. 22.5%, p < 0.0001), and 3rd Rec (2-year survival 88.9 vs. 30.8%, p = 0.005). CONCLUSIONS: Aggressive local treatment of recurrent metastases may improve survival, even in the case of iterative recurrences and extrahepatic lesions. Surgery is the standard, but a multidisciplinary approach should be adopted to enlarge the pool of treatable patients.

RESUMO

BACKGROUND: The aim of this study is to report the results of transarterial embolization (TAE) in the setting of postoperative bleeding after hip surgery. METHODS: We retrospectively evaluated 40 patients (male:female = 15:25, median age = 68 years) who underwent TAE from 2006 to 2016: 77.5% underwent total hip arthroplasty, 20% open reduction internal fixation, and 2.5% external fixation. Preangiographic multidetector computed tomography angiography was performed in 20 (49%) cases, and 9 of them showed arterial extravasation. Twenty-seven TAEs were performed within a week from surgery; active bleeding was seen in 33 (80.5%) angiograms. Gelatin sponge, microparticles, coils, n-butyl cyanoacrylate, and combinations of them were used as embolic materials. RESULTS: Bleeding was controlled in all cases. The most frequently embolized arteries were branches of the deep femoral artery (n = 17). Permanent embolization agents (microparticles, coils, n-2-butyl-cyanoacrylate) were used in 88% of cases; temporary agents (gelfoam) in 12%. One procedure was complicated by arterial dissection. Hospital discharge averaged 20 days post-TAE (median = 17, range = 3-104). One-month survival rate was 97.5%. One patient died of ischemic bowel perforation. CONCLUSION: TAE is safe and effective in stopping the bleeding of the hip region and should be performed early, to avoid irreversible ischemic damage. Multidetector computed tomography angiography can be used to confirm doubtful evidence of ongoing bleeding. Several embolic materials can be used, each one offering different advantages. Low complication and mortality rates were observed. TAE seems to be the ideal first-line intervention when postoperative bleeding of the operated hip is detected.

RESUMO

BACKGROUND: The impact of fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) for patients with colorectal liver metastases (CLM) still is debated. Its relevance could be enhanced in the case of recurrent disease. The current study aimed to elucidate the role of PET-CT in restaging and treatment planning for recurrent CLM. METHODS: A series of 352 consecutive patients undergoing their first liver resection for CLM between 2005 and 2014 was reviewed. Of these patients, 224 (63.6 %) had a recurrence. The 107 patients who had received PET-CT at diagnosis of recurrence before chemotherapy were analyzed. CT was available in all cases, and magnetic resonance imaging (MRI) was available in 64 cases. RESULTS: Extrahepatic lesions were found in 59 patients. Liver and lung recurrences were detected with excellent sensitivity by CT/MRI and PET-CT (liver: 100 vs. 96.7 %; lung: 95.8 vs. 95.8 %). In detecting other recurrence sites, PET-CT had higher sensitivity than CT/MRI (91.5 vs. 54.2 %, p < 0.01; lymph nodes: 93.5 vs. 64.5 %, p = 0.011; peritoneum: 80 vs. 20 %, p = 0.023; bones: 87.5 vs. 37.5 %, nonsignificant difference). For 28.8 % (17/59) of the patients, the diagnosis of extrahepatic disease was obtained thanks to PET-CT (39.5 % considering nonpulmonary lesions). PET-CT modified treatment strategy in 16 (14.9 %) patients, excluding from surgery 15 (20.3 %) of 74 patients resectable at CT/MRI. This latter subgroup had a lower survival rate than the patients resectable after PET-CT (2-year survival, 22.7 vs. 77.8 %; p = 0.004), similar to the patients unresectable at CT/MRI (57.6 %). CONCLUSIONS: In the authors' experience, PET-CT has offered a relevant contribution to restaging of recurrent CLM. It disclosed one fourth of extrahepatic lesions and prevented worthless surgery for about 20 % of patients.

RESUMO

OBJECTIVES: To present the results of our experience with cyanoacrylic glue percutaneous injection to treat post-surgical non-healing enteric fistulae after failure of standard treatments. METHODS: Eighteen patients (14 males; age range 33-84, mean 69 years) were treated for a non-healing post-surgical enteric fistula after failure of standard treatments. Under computed tomography and/or fluoroscopic guidance, a mixture of cyanoacrylic glue (Glubran 2, GEM, Viareggio, Italy) and ethiodized oil was injected at the site of the fistula. Fistula was considered healed when no material was drained by the percutaneous drainage and a subsequent computed tomography confirmed the disappearance of any fluid collection. RESULTS: In all cases, it was possible to reach the site of the fistula using a percutaneous access. A median of 1 injection (range 1-5) was performed. Fistula healing was achieved in 16/18 (89 %) patients. One patient died for other reasons before fistula healing. Median time for fistula healing was 0 days (mean 8, range 0-58 days). No complications occurred. Reoperation was needed in one patient. CONCLUSIONS: Percutaneous injection of cyanoacrylic glue is feasible, safe, and effective to treat non-healing post-surgical enteric fistulae. It may represent a further option to avoid surgical reoperation in frail patients.

RESUMO

OBJECTIVES: To assess mid-term outcome of biodegradable biliary stents (BBSs) to treat benign biliary strictures refractory to standard bilioplasty. METHODS: Institutional review board approval was obtained and patient consent was waived. 107 patients (61 males, 46 females, mean age 59 ± 16 years), were treated. Technical success and complications were recorded. Ninety-seven patients (55 males, 42 females, aged 57 ± 17 years) were considered for follow-up analysis (mean follow-up 23 ± 12 months). Fisher's exact test and Mann-Whitney U tests were used and a Kaplan-Meier curve was calculated. RESULTS: The procedure was always feasible. In 2/107 cases (2 %), stent migration occurred (technical success 98 %). 4/107 patients (4 %) experienced mild haemobilia. No major complications occurred. In 19/97 patients (18 %), stricture recurrence occurred. In this group, higher rate of subsequent cholangitis (84.2 % vs. 12.8 %, p = 0.001) and biliary stones (26.3 % vs. 2.5 %, p = 0.003) was noted. Estimated mean time to stricture recurrence was 38 months (95 % C.I 34-42 months). Estimated stricture recurrence rate at 1, 2, and 3 years was respectively 7.2 %, 26.4 %, and 29.4 %. CONCLUSION: Percutaneous placement of a BBS is a feasible and safe strategy to treat benign biliary strictures refractory to standard bilioplasty, with promising results in the mid-term period. KEY POINTS: • Percutaneous placement of a BBS is 100 % feasible. • The procedure appears free from major complications, with few minor complications. • BBSs offer promising results in the mid-term period. • With a BBS, external catheter/drainage can be removed early. • BBSs represent a new option in treating benign biliary stenosis.

RESUMO

PURPOSE: In recent decades, the use of radiopharmaceuticals in the assessment of hepatocellular carcinoma (HCC) has become established, and new findings indicate that radiolabelled choline has considerable potential in this setting. Therefore, in this study we aimed to assess the diagnostic role of (11)C-choline positron emission tomography (PET)/CT, compared with conventional imaging with CT/MRI, in patients with HCC. METHODS: The study population comprised 45 patients (male to female ratio = 37:8, median age 70.5 years) referred to our institution owing to HCC: 27 at initial diagnosis and 18 for restaging after recurrence. In all cases we performed whole-body (11)C-choline PET/CT and compared its findings with contrast-enhanced CT (n = 35) or MRI (n = 29) or both (n = 15) for a total of 50 paired scans. The reference standard was either histological proof (21 patients) or a multidisciplinary consensus. Diagnostic accuracy was then determined in a scan-based (SBA) and a lesion-based analysis (LBA). RESULTS: On SBA the sensitivity and specificity for PET were 88 and 90 %, respectively, whereas for CT/MRI they were 90 and 73 %, respectively (p > 0.05). On LBA the overall sensitivity and specificity were 78 and 86 %, respectively, for PET vs 65 and 55 % for CT/MRI. Overall we investigated 168 disease sites, of which 100 were in the liver and 68 were extrahepatic. When considering only liver lesions, (11)C-choline PET and CT/MRI showed an accuracy of 66 and 85 %, respectively, while for extrahepatic lesions PET showed an accuracy of 99 %, while the accuracy of CT/MRI was 32 %. In both cases, there was a statistically significant difference in accuracy between the two modalities (p < 0.01). Combination of the PET results with those of CT/MRI resulted in the highest diagnostic accuracy in both analyses, at 92 % for SBA and 96 % for LBA. In 11 patients (24 %) the PET findings modified the therapeutic strategy, the modification proving appropriate in 10 of them. CONCLUSION: (11)C-Choline PET showed good accuracy in investigating patients with HCC and prompted a change in treatment planning in almost one fourth of patients. The main strength of (11)C-choline PET/CT resides in its ability to detect extrahepatic HCC localizations, but the combination with conventional imaging modalities allowed for the highest diagnostic accuracy.

RESUMO

A systematic review of the clinical safety and efficacy of percutaneous breast cancer cryoablation was performed. Of 202 papers screened, seven matched the inclusion criteria. Cryoablation was mainly performed under ultrasound guidance, and on average two cryoprobes were used. Complete local tumor control was noted in 73% of patients (mean follow-up, 8 mo). No major complications were noted. The cosmetic outcome was satisfactory. Breast cancer cryoablation is safe, although local tumor control is suboptimal. The best results are achieved with small (<15 mm) ductal tumors treated by application of multiple cryoprobes.

RESUMO

PURPOSE: This paper presents a new magnetic resonance angiography (MRA) protocol for the evaluation of thoracic outlet syndrome (TOS) that allows for a separate assessment of veins and arteries while using a single, simultaneous and bilateral (SB-MRA) single contrast injection, valid for both abduction and adduction acquisitions. MATERIALS AND METHODS: From 2009 to 2013 we performed 38 MRA studies for clinically suspected TOS (13 M, 25 F; mean age, 35.9 years; σ = 11.13). Twin peripheral 20G intravenous catheters were placed in a cubital vein in both arms and connected to a single power injector by two lines joined with a connector. A 3T MR system with a wide gantry was used. Two groups of four radiologists assessed all the images. Group A judged the full examinations, Group B had only the late acquisitions. Differences were evaluated using the Chi square test. TOS was confirmed only after integration with the clinical history. RESULTS: Seventeen (45 %) patients were diagnosed with predominant venous TOS (VTOS), nine (24 %) with predominant arterial TOS (ATOS) and 12 (32 %) had an indeterminate or nonvascular condition. Group A radiologists identified significantly more VTOS than group B (p = 0.049). Interobserver agreement was very high. CONCLUSIONS: SB-MRA is a safe and reliable protocol for the study of TOS. It provides a supplementary early acquisition that allows for separate assessment of veins and arteries, permits the investigation of the collateral venous flow with a single injection of contrast material and provides a higher diagnostic power for VTOS. SB-MRA is helpful for the diagnosis of TOS of vascular origin.

RESUMO

BACKGROUND: Contrast-enhanced intra-operative ultrasound (CE-IOUS) for colorectal liver metastases (CLMs) has become a part of clinical practice. Whether it should be selectively or routinely applied remains unclear. The aim of this study was to define criteria for the use of CE-IOUS. METHODS: One-hundred and twenty-seven patients underwent a hepatectomy for CLMs using IOUS and CE-IOUS. All patients underwent computed tomography (CT) and/or magnetic resonance imaging (MRI) within 2 weeks prior to surgery. The reference was histology, and imaging at 6 months after surgery. Univariate and multivariate analyses were performed. Statistical significance was set at P = 0.05. RESULTS: Using IOUS an additional 172 lesions in 51 patients were found. CE-IOUS found 14 additional lesions in 6 patients. Seventy-eight CLMs in 38 patients appeared within 6 months after surgery. The sensitivity, specificity, positive- and negative-predictive value were 63%, 98%, 100% and 27% for pre-operative imaging, 87%, 100%, 100% and 52% for IOUS, and 89%, 100%, 100% and 56% for IOUS+CE-IOUS, respectively. CE-IOUS allowed better tumour margin definition in 23 patients (18%), thus assisting resection. Analyses indicated that the presence of multiple (P = 0.014), and isoechoic CLMs (P = 0.049) were independently correlated with new findings at CE-IOUS. CONCLUSIONS: Compared with IOUS, CE-IOUS improved detection and resection guidance. These additions are significant and demand its use in cases with multiple and isoechoic CLMs.

RESUMO

BACKGROUND: Pancreatogenic diabetes, a consequence of pancreatic tissue loss following pancreatectomy, poses a significant challenge for patients undergoing pancreatic surgery. Islet autotransplantation (IAT) offers a promising approach to prevent or alleviate pancreatogenic diabetes, but its application has been limited to individuals with painful chronic pancreatitis. METHODS: This study presents a 15-y clinical experience with the Milan Protocol, which expands IAT after pancreatectomy to a broader spectrum of patients with malignant and nonmalignant pancreatic diseases. The analysis evaluates feasibility, efficacy, and safety of IAT. Modified Igls criteria validated through the arginine test and mixed meal tolerance tests were used to assess long-term metabolic outcomes. RESULTS: Between November 2008 and June 2023, IAT procedures were performed on 114 of 147 candidates. IAT-related complications occurred in 19 of 114 patients (16.7%), with 5 being potentially serious. Patients exhibited sustained C-peptide secretion over the 10-y follow-up period, demonstrating a prevalence of optimal and good beta-cell function. Individuals who underwent partial pancreatectomy demonstrated superior metabolic outcomes, including sustained C-peptide secretion and a reduced risk of developing diabetes or insulin dependence compared with those who underwent total pancreatectomy. For patients who had total pancreatectomy, the quantity of infused islets and tissue volume were identified as critical factors influencing metabolic outcomes. An increased risk of recurrence or progression of baseline diseases was not observed in subjects with neoplasms. CONCLUSIONS: These findings provide valuable insights into the benefits and applications of IAT as a therapeutic option for pancreatogenic diabetes after pancreatic surgery, expanding its potential beyond painful chronic pancreatitis.

RESUMO

OBJECTIVES: To evaluate feasibility, safety, and outcome of patients treated with biodegradable biliary stents for benign biliary stenosis refractory to other treatments. METHODS: Between March 2011 and September 2012, ten patients (seven men, three women; age 59 ± 7 years) with recurrent cholangitis due to postsurgical biliary stricture, previous multiple unsuccessful (two to five) bilioplasties, and unsuitability for surgical/endoscopic repair underwent percutaneous implantation of a biodegradable biliary stent. Patients were followed-up clinically and with ultrasound at 1, 3 and 6 months, and then at 6-month intervals. RESULTS: Stent implantation was always feasible. No immediate major or minor complications occurred. In all patients, 48-h cholangiographic control demonstrated optimal stent positioning and stenosis resolution. In a median follow-up time of 16.5 months (25th-75th percentiles = 11-20.25 months) no further invasive treatment was needed. Three patients experienced transient episodes of cholangitis. Neither re-stenosis nor dilatation of the biliary tree was documented during follow-up. No stent was visible at the 6-month follow-up. CONCLUSIONS: Percutaneous placement of biodegradable biliary stents represents a new option in treating benign biliary stenoses refractory to treatment with bilioplasty. This technique seems to be feasible, effective and free from major complications. Further investigations are warranted to confirm our preliminary results.

RESUMO

There is still debate over how reviewing oncological histories and addressing appropriate therapies in multidisciplinary team (MDT) discussions may affect patients' overall survival (OS). The aim of this study was to describe MDT outcomes for a single cancer center's patients affected by colorectal liver metastases (CRLMs). From 2010 to 2020, a total of 847 patients with CRLMs were discussed at our weekly MDT meeting. Patients' characteristics and MDT decisions were analyzed in two groups: patients receiving systemic therapy (ST) versus patients receiving locoregional treatment (LRT). Propensity-score matching (PSM) was run to reduce the risk of selection bias. The median time from MDT indication to treatment was 27 (IQR 13−51) days. The median OS was 30 (95%CI = 27−34) months. After PSM, OS for patients undergoing LRT was 51 (95%CI = 36−64) months compared with 15 (95%CI = 13−20) months for ST patients (p < 0.0001). In this large retrospective study, the MDT discussions were useful in providing the patients with all available locoregional options.

RESUMO

Alterations in nutritional status, in particular sarcopenia, have been extensively associated with a poor prognosis in cirrhotic patients regardless of the etiology of liver disease. Less is known about the predictive value of myosteatosis, defined as pathological fat infiltration into the skeletal muscle. We retrospectively analyzed a cohort of 151 cirrhotic patients with unresectable hepatocellular carcinoma (HCC) who underwent their first trans-arterial embolization (TAE) between 1 March 2011 and 1 July 2019 at our Institution. Clinical and biochemical data were collected. Sarcopenia was assessed using the L3-SMI method while myosteatosis with a dedicated segmentation suite (3D Slicer), using a single slice at an axial plane located at L3 and calculating the IMAC (Intramuscular Adipose Tissue Content Index). The sex-specific cut-off values for defining myosteatosis were IMAC > −0.44 in males and >−0.31 in females. In our cohort, 115 (76%) patients were included in the myosteatosis group; 128 (85%) patients had a coexistent diagnosis of sarcopenia. Patients with myosteatosis were significantly older and showed higher BMI than patients without myosteatosis. In addition, male gender and alcoholic- or metabolic-related cirrhosis were most represented in the myosteatosis group. Myosteatosis was not associated with a different HCC burden, length of hospitalization, complication rate, and readmission in the first 30 days after discharge. Overall survival was not influenced by the presence of myosteatosis.

RESUMO

Background: Hepatocellular carcinoma (HCC) is the most frequent liver malignancy and a leading cause of cancer death in the world. In unresectable HCC patients, transcatheter arterial (chemo-) embolization (TAE/TACE) has shown a disease response in 15-55% of cases. Though multiple TAE/TACE courses can be administered in principle, Stereotactic Body Radiotherapy (SBRT) has emerged as an alternative option in the case of local relapse following multiple TAE/TACE courses. Methods: This is a single-center, prospective, randomized, controlled, parallel-group superiority trial of SBRT versus standard TAE/TACE for the curative treatment of the intermediate stage of HCC after an incomplete response following TAE/TACE (NCT02323360). The primary endpoint is 1-year local control (LC): 18 events were needed to assess a 45% difference (HR: 0.18) in favor of SBRT. The secondary endpoints are 1-year Progression-Free Survival (PFS), Distant Recurrence-Free Survival (DRFS), Overall Survival (OS) and the incidence of acute and late complications. Results: At the time of the final analysis, 40 patients were enrolled, 19 (49%) in the TAE/TACE arm and 21 (51%) in the SBRT arm. The trial was prematurely closed due to slow accrual. The 1- and 2-year LC rates were 57% and 36%. The use of SBRT resulted in superior LC as compared to TAE/TACE rechallenge (median not reached versus 8 months, p = 0.0002). PFS was 29% and 16% at 1 and 2 years, respectively. OS was 86% and 62% at 1 year and 2 years, respectively. In the TAE arm, PFS was 13% and 6% at 1 and 2 years, respectively. In the SBRT arm, at 1 and 2 years, PFS was 37% and 21%, respectively. OS at 1 and 2 years was 75% and 64% in the SBRT arm and 95% and 57% in the TACE arm, respectively. No grade >3 toxicity was recorded. Conclusions: SBRT is an effective treatment option in patients affected by inoperable HCC experiencing an incomplete response following ≥1 cycle of TAE/TAC.
