Pulmonary Artery Embolization in the Management of Hemoptysis Related to Lung Tumors.

(1) Background: Bronchial artery embolization has been shown to be effective in the management of neoplastic hemoptysis. However, knowledge of pulmonary artery embolization is lacking. The aim of this study was to evaluate the safety and efficacy of pulmonary artery embolization in patients presenting with hemoptysis related to lung tumors. (2) Methods: This retrospective study reviewed all consecutive patients with cancer and at least one episode of hemoptysis that required pulmonary artery embolization from December 2008 to December 2020. The endpoints of the study were technical success, clinical success, recurrence of hemoptysis and complications. (3) Results: A total of 92 patients were treated with pulmonary artery embolization (63.1 years ± 9.9; 70 men). Most patients had stage III or IV advanced disease. Pulmonary artery embolization was technically successful in 82 (89%) patients and clinically successful in 77 (84%) patients. Recurrence occurred in 49% of patients. Infectious complications occurred in 15 patients (16%). The 30-day mortality rate was 31%. At 3 years, the survival rate was 3.6%. Tumor size, tumor cavitation and necrosis and pulmonary artery pseudoaneurysm were significantly associated with recurrence and higher mortality. (4) Conclusions: Pulmonary artery embolization is an effective treatment to initially control hemoptysis in patients with lung carcinoma, but the recurrence rate remains high and overall survival remains poor.

Long-Term Oncological and Functional Outcomes after Laparoscopic Partial Nephrectomy with Hyperselective Embolization of Tumor Vessels in a Hybrid Operating Room.

Laparoscopic partial nephrectomy (LPN) after hyperselective embolization of tumor vessels (HETV) in a hybrid operating room (HOR) that combines traditional surgical equipment with advanced imaging technology, is a non-clamping surgical approach to treat localized kidney tumors that has shown promising short-term results. The aim of this study was to evaluate the long-term oncological and functional outcomes of this procedure. All consecutive patients treated for a localized kidney tumor by LPN after HETV between May 2015 and October 2022 in a single academic institution were included in the study. Clinical, pathological and biological data were collected prospectively in the uroCCR database. We evaluated intraoperative data, postoperative complications, surgical margin and modification of renal function after surgery. We included 245 patients. The median tumor size was 3.2 (2.5-4.4) cm. The R.E.N.A.L. complexity was low, medium and high for 104 (43.5%), 109 (45.6%) and 26 (10.9%) patients, respectively. Median LPN time was 75 (65-100) min and median blood loss was 100 (50-300) mL. Surgical postoperative complications occurred in 56 (22.9%) patients with 17 (5.7%) major complications. The median Glomerular Function Rate variation at 6 months was -7.5 (-15--2) mL/min. Malignant tumors were present in 211 (86.1%) patients, and 12 (4.9%) patients had positive surgical margins. After a median follow-up of 27 (8-49) months, 20 (8.2%) patients had a tumor recurrence and 4 (1.6%) died from cancer. At 5 years, disease free survival, cancer specific survival and overall survival rates were 84%, 96.8% and 88.3%, respectively. Performing LPN after HETV in a HOR is a safe and efficient non-clamping approach to treat localized kidney tumors.

Endovascular Thrombectomy for Acute Iliofemoral Deep Venous Thrombosis Through a Jugular Approach with a Rotational Device.

PURPOSE: To report the effectiveness of pharmacomechanical catheter-directed thrombolysis (PCDT) in the management of acute iliofemoral deep venous thrombosis (DVT) via the jugular vein using a slow rotation and large-tip device (SRD) in a large cohort of patients. MATERIAL AND METHODS: From 2011 to 2021, 277 patients (mean age 45 years, 59.2% women) were treated in 6 centres with PCDT for ilio-fémoral DVT. PCDT was performed via the jugular vein and consisted of one session of fragmentation-fibrinolysis, aspiration and, if needed, angioplasty with stenting. The aim of PCDT was to achieve complete clearance of the venous thrombosis and to restore iliofemoral patency. Residual thrombotic load was assessed by angiography, venous patency by duplex ultrasound and clinical effectiveness by the rate of post-thrombotic syndrome (Villalta score > 4). RESULTS: All patients were treated via the jugular vein using an SRD, and all but one were treated with fibrinolysis. Angioplasty with stenting was performed in 84.1% of patients. After the procedure, the residual thrombotic load at the ilio-fémoral region was < 10% in 96.1% of patients. The rate of major complications was 1.8% (n = 5), the rate of minor complications was 4% (n = 11), and one patient died from pulmonary embolism (0.4%) At a median follow-up of 24 months, primary and secondary iliofemoral patency was 89.6% and 95.8%, respectively. The rate of PTS was 13.8% at 12 months. CONCLUSION: PCDT via the jugular vein using an SRD is an efficient treatment for acute iliofemoral DVT and results in high long-term venous patency and low PTS rates. Level of evidence Level 4, Case series.

Left gastric vein embolization during TIPS placement for acute variceal bleeding has no effect on bleeding recurrence: Results of a multicenter study.

PURPOSE: The purpose of this study was to evaluate whether concomitant left gastric vein embolization (LGVE) during transjugular intrahepatic portosystemic shunt (TIPS) for acute variceal hemorrhage could reduce the risk of bleeding recurrence. MATERIAL AND METHOD: A national multicenter observational study was conducted in 14 centers between January 2019 and December 2020. All cirrhotic patients who underwent TIPS placement for acute variceal bleeding were included. During TIPS procedure, size of left gastric vein (LGV), performance of LGVE, material used for LGVE and portosystemic pressure gradient (PPG) before and after TIPS placement were collected. A propensity score for the occurrence of LGVE was calculated to assess effect of LGVE on rebleeding recurrence at six weeks and one year. RESULTS: A total of 356 patients were included (mean age 57.3 ± 10.8 [standard deviation] years; 283/356 [79%] men). Median follow-up was 11.2 months [interquartile range: 1.2, 13.3]. The main indication for TIPS was pre-emptive TIPS (162/356; 46%), rebleeding despite secondary prophylaxis (105/356; 29%), and salvage TIPS (89/356; 25%). Overall, 128/356 (36%) patients underwent LGVE during TIPS procedure. At six weeks and one year, rebleeding-free survival did not differ significantly between patients who underwent LGVE and those who did not (6/128 [5%] vs. 15/228 [7%] at six weeks, and 11/128 [5%] vs. 22/228 [7%] at one year, P = 0.622 and P = 0.889 respectively). A total of 55 pairs of patients were retained after propensity score matching. In patients without LGVE, the rebleeding rate was not different from those with LGVE (3/55 [5%] vs. 4/55 [7%], P > 0.99, and 5/55 [9%] vs. 6/55[11%], P > 0.99, at six weeks and one year respectively). Multivariable analysis identified PPG after TIPS placement as the only predictor of bleeding recurrence (hazard ratio = 1.09; 95% confidence interval: 1.02-1.18; P = 0.012). CONCLUSION: In this multicenter national real-life study, we did not observe any benefit of concomitant LGVE during TIPS placement for acute variceal bleeding on bleeding recurrence rate.

Defining textbook outcome for selective internal radiation therapy of hepatocellular carcinoma: an international expert study.

BACKGROUND: A textbook outcome (TO) is a composite indicator covering the entire intervention process in order to reflect the "ideal" intervention and be a surrogate for patient important outcomes. Selective internal radiation therapy (SIRT) is a complex multidisciplinary and multistep intervention facing the challenge of standardization. This expert opinion-based study aimed to define a TO for SIRT of hepatocellular carcinoma. METHODS: This study involved two steps: (1) the steering committee (4 interventional radiologists) first developed an extensive list of possible relevant items reflecting an optimal SIRT intervention based on a literature review and (2) then conducted an international and multidisciplinary survey which resulted in the final TO. This survey was online, from February to July 2021, and consisted three consecutive rounds with predefined settings. Experts were identified by contacting senior authors of randomized trials, large observational studies, or studies on quality improvement in SIRT. This study was strictly academic. RESULTS: A total of 50 items were included in the first round of the survey. A total of 29/40 experts (73%) responded, including 23 interventional radiologists (79%), three nuclear medicine physicians (10%), two hepatologists, and one oncologist, from 11 countries spanning three continents. The final TO consisted 11 parameters across six domains ("pre-intervention workup," "tumor targeting and dosimetry," "intervention," "post-90Y imaging," "length of hospital stay," and "complications"). Of these, all but one were applied in the institutions of > 80% of experts. CONCLUSIONS: This multidimensional indicator is a comprehensive standardization tool, suitable for routine care, clinical round, and research.

Evaluating the Effectiveness of Yttrium-90 Glass Microspheres in the Treatment of Hepatocellular Carcinoma, Intrahepatic Cholangiocarcinoma, and Metastatic Colorectal Cancer in Practice: Protocol for the Prospective PROACTIF Phase IV Registry Study in France.

PRIMARY OBJECTIVE: Recently, selective internal radiation therapy using yttrium-90 (Y90) glass microspheres (TheraSphere™) was approved for reimbursement by health authorities in France. The PROACTIF study aims to gather data on effectiveness, patient quality of life, and safety with use of Y90 glass microspheres in real-world clinical settings in France. INCLUSION CRITERIA: Patient with a diagnosis of hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (iCC), and/or metastatic colorectal cancer (mCRC) who was treated with a dose of Y90 glass microspheres that has been reimbursed in France and who do not oppose use of their personal medical data. EXCLUSION CRITERIA: If data collection is opposed, treatment is reimbursed but not administered, or treatment is administered but not reimbursed. OUTCOME MEASURES: Primary outcome measures include overall survival from time of Y90 glass microsphere treatment and quality of life, as assessed using the Functional Assessment of Cancer Therapy- Hepatobiliary questionnaire. ESTIMATED NUMBER OF PATIENTS TO BE INCLUDED: This is an open study and there is no set number of patients; 115 have already been enrolled. PLANNED SUBGROUP ANALYSES: Analyses will be stratified by disease state (HCC, iCC, or mCRC). Subgroups to be analyzed include age group, unilobar/bilobar disease at baseline, Eastern Cooperative Oncology Group (ECOG) status at baseline, liver tumor burden at baseline, target lesion size, and standard versus multi-compartment personalized dosimetry treatment. PLANNED RECRUITMENT AND OBSERVATION PERIOD: Recruitment includes patients who are prescribed and treated with a commercial vial of Y90 glass microspheres between 01 January 2019 and 31 December 2024. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04069468.

Short-term Safety and Quality of Life Outcomes Following Radioembolization in Primary and Secondary Liver Tumours: a Multi-centre Analysis of 200 Patients in France.

PURPOSE: Radioembolization has emerged as a treatment modality for patients with primary and secondary liver tumours. This observational study CIRT-FR (CIRSE Registry for SIR-Spheres Therapy in France) aims to evaluate real-life clinical practice on all patients treated with transarterial radioembolization (TARE) using SIR-Spheres yttrium-90 resin microspheres in France. In this interim analysis, safety and quality of life data are presented. Final results of the study, including secondary effectiveness outcomes, will be published later. Overall, CIRT-FR is aiming to support French authorities in the decision making on reimbursement considerations for this treatment. METHODS: Data on patients enrolled in CIRT-FR from August 2017 to October 2019 were analysed. The interim analysis describes clinical practice, baseline characteristics, safety (adverse events according to CTCTAE 4.03) and quality of life (according to EORTC QLQ C30 and HCC module) aspects after TARE. RESULTS: This cohort included 200 patients with hepatocellular carcinoma (114), metastatic colorectal cancer (mCRC; 38) and intrahepatic cholangiocarcinoma (33) amongst others (15). TARE was predominantly assigned as a palliative treatment (79%). 12% of patients experienced at least one adverse event in the 30 days following treatment; 30-day mortality was 1%. Overall, global health score remained stable between baseline (66.7%), treatment (62.5%) and the first follow-up (66.7%). CONCLUSION: This interim analysis demonstrates that data regarding safety and quality of life generated by randomised-controlled trials is reflected when assessing the real-world application of TARE. TRIAL REGISTRATION: Clinical Trials.gov NCT03256994.

Renal function after partial nephrectomy following intra-arterial embolization of renal tumors.

Laparoscopic Partial Nephrectomy (LPN) after intra-arterial Embolization of renal tumors (LPNE) in a hybrid operating room allows renal tumor enucleation without dissection and clamping of the renal pedicle. The purpose was to assess the potential negative impact of embolization on the renal function. This prospective monocentric study included all patients treated with LPNE between May 2015 and June 2019. Clinical data was collected and incorporated into the UroCCR database (NCT03293563). Glomerular Filtration Rate (GFR) and Computed Tomography Renal Volume (CTRV) were compared before and after 6 months following LPNE. The mean post-operative GFR was 86.6 mL/min (SD 22.9). The mean GFR loss was 9.4% (SD 15.1) and the median renal parenchyma loss was 21 mL (SD 20.6). Using a threshold of 25% GFR loss, age was the only significant predictive factor of renal function impairment according to bivariate (59.5 vs 69.3 years, p = 0.017) and multivariable analysis (OR 1.075, CI 1-1.2], p = 0.05). Significant renal function impairment was not correlated with the renal parenchymal volume loss (OR 0.987, CI [0.95-1.02], p = 0.435). Renal function impairment after LPNE seems to be comparable to other techniques of partial nephrectomy.

Study protocol of the HYPER-LIV01 trial: a multicenter phase II, prospective and randomized study comparing simultaneous portal and hepatic vein embolization to portal vein embolization for hypertrophy of the future liver remnant before major hepatectomy for colo-rectal liver metastases.

BACKGROUND: In patients undergoing major liver resection, portal vein embolization (PVE) has been widely used to induce hypertrophy of the non-embolized liver in order to prevent post-hepatectomy liver failure. PVE is a safe and effective procedure, but does not always lead to sufficient hypertrophy of the future liver remnant (FLR). Hepatic vein(s) embolization has been proposed to improve FLR regeneration when insufficient after PVE. The sequential right hepatic vein embolization (HVE) after right PVE demonstrated an incremental effect on the FLR but it implies two different procedures with no time gain as compared to PVE alone. We have developed the so-called liver venous deprivation (LVD), a combination of PVE and HVE during the same intervention, to optimize the phase of liver preparation before surgery. The main objective of this randomized phase II trial is to compare the percentage of change in FLR volume at 3 weeks after LVD or PVE. METHODS: Patients eligible to this multicenter prospective randomized phase II study are subjects aged from 18 years old suffering from colo-rectal liver metastases considered as resectable and with non-cirrhotic liver parenchyma. The primary objective is the percentage of change in FLR volume at 3 weeks after LVD or PVE using MRI or CT-Scan. Secondary objectives are assessment of tolerance, post-operative morbidity and mortality, post-hepatectomy liver failure, rate of non-respectability due to insufficient FLR or tumor progression, per-operative difficulties, blood loss, R0 resection rate, post-operative liver volume and overall survival. Objectives of translational research studies are evaluation of pre- and post-operative liver function and determination of biomarkers predictive of liver hypertrophy. Sixty-four patients will be included (randomization ratio 1:1) to detect a difference of 12% at 21 days in FLR volumes between PVE and LVD. DISCUSSION: Adding HVE to PVE during the same procedure is an innovative and promising approach that may lead to a rapid and major increase in volume and function of the FLR, thereby increasing the rate of resectable patients and limiting the risk of patient's drop-out. TRIAL REGISTRATION: This study was registered on clinicaltrials.gov on 15th February 2019 (NCT03841305).

Blue Dye Embolization of Renal Tumor: A New Technique to Improve Tumor Localization During Laparoscopic Partial Nephrectomy.

Purpose: To improve the tumor localization during laparoscopic surgery, we describe an innovative technique involving superselective intra-arterial injection of blue dye in tumoral vessels to color the tumor before surgical enucleation. Materials and Methods: The dye injection was performed at the same time as superselective embolization, immediately before laparoscopic surgery in a hybrid operating room. We used this new treatment sequence on 50 consecutive patients. Results: The selective intra-arterial injection of an emulsion of blue dye and lipiodol was feasible in 46 (92%) cases and well tolerated, followed by superselective embolization of the tumor vessels with glue or coils. The tumor was easily localized during surgery due to the blue coloration. Tumor coloration was not associated with postoperative complication, especially allergic reaction or renal failure. Pathologic analysis of the tumor was not modified by the coloration and all tumors had negative surgical margins. Conclusions: The preoperative dye localization is a feasible, safe, and accurate procedure. This combined approach reduces the difficulty of surgery and increases patient safety.

Study of Renal and Kidney Tumor Vascularization Using Data from Preoperative Three-dimensional Arteriography Prior to Partial Nephrectomy.

BACKGROUND: In a cadaveric model with healthy kidneys, it has recently been highlighted that a single renal segment could be supplied by one or more arterial branches originating from an artery supplying another segment. OBJECTIVE: To demonstrate occurrences of anatomical variations of renal vascularization and to analyze vascularization of renal tumors. DESIGN, SETTING, AND PARTICIPANTS: This prospective monocentric study included all patients treated for a renal tumor between May 2015 and June 2017 by laparoscopic partial nephrectomy after superselective tumor embolization in a hybrid operating room. INTERVENTION: Three-dimensional renal and tumoral arteriography with cone-beam computed tomography scan was performed, coupled with preoperative cross-sectional imaging. This procedure provided an accurate vascular anatomical mapping of the kidney and allowed further analysis of tumor vascularization. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Relation between anatomical variations of the vascularization and perioperative data was assessed. A χ2 test or Fisher's test was used for qualitative variables, and a Student t test was used for quantitative variables. RESULTS AND LIMITATIONS: Out of the 60 patients included, only 25 (42%) presented a standard vascular subdivision. In 26 patients (43%), tumors were supplied by more than one branch and in 20 patients (33%), there was a branch supplying the tumor from another segment. In these cases of multiple or multi-segmental tumor vascularization, tumor size, operative duration, and duration of embolization were significantly higher than in the case of standard vascularization. These complex tumors were more often located at the upper pole of the kidney or at the junction of the anterior and posterior vascular territories of the kidney. Limitations of this study include the low number of patients and its monocentricity. CONCLUSIONS: This study confirms that renal vascularization frequently differs from Graves' reference model and that tumor vascularization can depend on several segmental branches. This vascular complexity explains surgical difficulties and must be taken into consideration when segmental arterial clamping is considered during partial nephrectomy. PATIENT SUMMARY: We studied renal and tumor vascularization using three-dimensional preoperative arteriography data on tumor kidneys. We have shown that there is great variability in renal vascularization and that tumors can be vascularized branches that originate from an artery leading to another segment. This vascular complexity explains surgical difficulties and must be taken into consideration when segmental arterial clamping is considered during partial nephrectomy.

Idarubicin-loaded Beads for Chemoembolization of Hepatocellular Carcinoma: The IDASPHERE II Single-Arm Phase II Trial.

Background A prior in vitro study showed that idarubicin was the most cytotoxic agent for hepatocellular carcinoma (HCC) cell lines. Idarubicin-loaded beads for transarterial chemoembolization (TACE) were previously evaluated for the appropriate dose in a phase I dose-escalation study. Purpose To evaluate objective response rate (ORR), safety, and survival after TACE by using idarubicin-loaded beads for unresectable HCC. Materials and Methods This prospective single-arm phase II study was conducted between January 2015 and January 2017. Participants with unresectable HCC were included in the trial and underwent TACE with idarubicin-eluting beads. The primary end point was 6-month ORR assessed with independent central review by using modified Response Evaluation Criteria in Solid Tumors. Secondary end points were best ORR during the first 6 months, overall survival, progression-free survival, time to progression, and safety. A two-stage Fleming statistical design was used. Results Forty-six study participants (mean age, 71.2 years ± 10.2; six women and 40 men) were included; 44 participants underwent at least one TACE session. The 6-month ORR was 52% (23 of 44). The best ORR achieved was 68% (30 of 44). Fourteen of 44 (32%) participants underwent a curative treatment after TACE. Median progression-free survival, time to progression, and overall survival were 6.6 months, 9.5 months, and 18.6 months, respectively. TACE was discontinued for toxicity in four of 44 (9%) participants. The most frequent grade 3-4 adverse events were elevated aspartate aminotransferase (14 of 44, 32%), elevated γ-glutamyl transpeptidase (eight of 44, 18%), hyperbilirubinemia (seven of 44, 16%), elevated alanine aminotransferase (seven of 44, 16%), and pain (seven of 44, 16%). Conclusion Idarubicin-eluting beads showed a good safety profile and promising objective response rate and time to progression when used as part of a transarterial chemoembolization regimen for unresectable hepatocellular carcinoma. © RSNA, 2019 See also the editorial by Padia in this issue.

Laparoscopic Partial Nephrectomy After Selective Embolization and Robot-Assisted Partial Nephrectomy: A Comparison of Short-Term Oncological and Functional Outcomes.

BACKGROUND: Partial nephrectomy (PN) is the standard treatment for localized renal tumors. Laparoscopic PN (LPN) after selective embolization of tumor (LPNE) in a hybrid operating room has been developed to make LPN easier and safer. The aim of this study was to compare outcomes of LPNE and robot-assisted PN (RAPN). PATIENTS AND METHODS: All patients who underwent an LPNE at Angers University Hospital between May 2015 and April 2017, and a RAPN at Diaconesses Croix Saint Simon hospital between October 2014 and April 2017 were prospectively included. The functional outcomes were evaluated using the change of estimated glomerular filtration rate (eGFR) at 1 month, and the oncological outcomes were evaluated using the positive surgical margin (PSM) rate. RESULTS: Fifty-seven patients underwent LPNE and 48 underwent RAPN. There was no difference between oncological and functional outcomes, with 2 PSM (4.4%) in the LPNE group and 4 PSM (10.3%) in the RAPN group (P = .32), and a mean change in eGFR at 1 month of -5.5% for LPNE and -8.3% for RAPN (P = .17). The mean surgical time was shorter in the LPNE group (150 vs. 195 minutes; P < .001), and mean estimated blood loss was less in the LPNE group (185 vs. 345 mL; P = .04). CONCLUSION: The short-term oncological and functional outcomes for LPNE were comparable with those for RAPN. A longer follow-up and a larger cohort of patients would be necessary to verify the benefits of LPNE, which appears to be a very interesting alternative to RAPN.

Laparoscopic partial nephrectomy following tumor embolization in a hybrid room. Feasibility and clinical outcomes.

PURPOSE: In order to limit ischemia and operative bleeding during and after partial nephrectomy we developed a clampless laparoscopic technique, in a hybrid operating room, immediately after super-selective arterial embolization of the renal tumor. We evaluated feasibility and morbidity of this new approach of zero ischemia in partial nephrectomy. METHODS: We included prospectively 50 consecutive patients treated in a hybrid operating room by this new technique for a localized renal tumor in a university hospital between May 2015 and January 2017. We evaluated perioperative data, postoperative complications, surgical margin and modification of renal function one month after surgery. Renal tumor complexity was evaluated by the R.E.N.A.L. score. RESULTS: We included 30 (60%) men and 20 (40%) women with a median age of 61 years (32-84) and a median BMI of 26.85 kg/m2 (20.1-46.4). Tumors were at low, median and high complexity in respectively 11 (22%), 32 (64%) and 7 (14%) cases. Median endovascular and surgical procedures durations were 43 min (16-120) and 80 min (32-150). Median blood loss was 100 mL (10-850). Two Clavien II complications occurred. Median length of hospital stay was 3 days (2-7). Renal function was not modified one month after partial nephrectomy. Median tumor size was 3 cm (1.2-8). Forty tumors (80%) were malignant and surgical margins were positive in one (2%). CONCLUSIONS: Clampless laparoscopic partial nephrectomy in a hybrid operating room without pedicular dissection after previous tumoral embolization is a technically safe and carcinologically efficient mini-invasive alternative for the management of localized renal tumors.

Hepatic Arterial Infusion Chemotherapy for Unresectable Liver Metastases of Colorectal Cancer: A Multicenter Retrospective Study.

INTRODUCTION: Hepatic arterial infusion chemotherapy (HAIC) is a treatment used for liver metastases (LM) of colorectal cancer (CRC). Because of its technical conditions, it has been used in only a few experienced centers in France. Our aim was to evaluate its feasibility, efficacy and tolerance in 4 centers. METHODS: Clinical, biological, and radiological data of patients treated with HAIC for unresectable LM from CRC in 4 institutions from October 2011 to January 2016 were retrospectively analyzed. RESULTS: Sixty-one patients with unresectable LM from CRC were included. Patients had previously received systemic chemotherapy in 95% of patients and 82.8% had previous oxaliplatin treatment. Oxaliplatin was administered using an intra-arterial route combined with intravenous (I.V.) Five-fluorouracil (5-FU) with leucovorin alone in 43.3% of patients, or combined with other I.V. chemotherapies or monoclonal antibodies in 56.7% of patients. Grade 3 to 4 clinical toxicities were reported in 16% of patients, including 9.8% of neurotoxicity, and Grade 3 to 4 biological toxicities were reported in 24.6% of patients including 22.2% with neutropenia. Catheter-related complications were observed in 31.1%. Tumor response rate in first- and second-line was 26.5% and third- and fourth-line was 11%. Median overall survival (OS) in first- and second-line was 13.5 months and third- and fourth-line was 8.3 months (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.39-1.12; P = .1729). Median progression-free survival (PFS) in first- and second-line was 9 months and third- and fourth-line were 6 months (HR, 0.53; 95% CI, 0.18-0.659; P = .0037). A secondary R0 resection was possible in 10 cases (16.4%) allowing a 2-year survival of 80%. CONCLUSION: These data confirm that in centers that recently developed HAIC using oxaliplatin, this treatment is feasible and has acceptable tolerance. The results, in terms of hepatic PFS, PFS, OS, and the rate of secondary resections of LM, are in the range of published data, and they confirm the interest of HAIC in patients in progression after multiple I.V.

Uterine Artery Embolization for Retained Products of Conception with Marked Vascularity: A Safe and Efficient First-Line Treatment.

OBJECTIVE: To report our clinical practice regarding a case series of retained products of conception (RPOC) with marked vascularity (MV) managed with selective uterine artery embolization (UAE) as first-line treatment. METHODS: This was a monocentric, retrospective study of 31 consecutive cases of RPOC with MV diagnosed by Doppler ultrasound in the context of postpartum/postabortal bleeding. The primary outcome was the absence of rebleeding following embolization. RESULTS: RPOC with MV occurred after abortion in 27 out of 31 patients (87%). The time elapsed between delivery/abortion and UAE ranged from 1 to 210 days (mean 55.7 ± 45 days). Primary clinical success was achieved in 23 women (74.2%) following a single embolization. In total, 27 out of 31 women (87%) had been exclusively managed by UAE with conservative success. Although procedural success was achieved in this number, six women had a further procedure to evacuate RPOC despite procedural success. Large uterine arteriovenous (AV) shunts associated with RPOC were observed in five cases (16.1%), among which two were successfully treated after a single UAE and one after two UAEs, while hysterectomy was performed in the last two cases despite two and three UAE procedures respectively. RPOC was histologically proven in ten cases (32.2%) including four out of five cases of uterine AV shunt. CONCLUSION: RPOC with MV can present with large uterine AV shunt, particularly in case of late management. Uterine artery embolization is an effective and safe first-line treatment, and should be evaluated for this indication in larger prospective trials.

Transjugular Intrahepatic Portosystemic Shunts With Covered Stents Increase Transplant-Free Survival of Patients With Cirrhosis and Recurrent Ascites.

BACKGROUND & AIMS: There is controversy over the ability of transjugular intrahepatic portosystemic shunts (TIPS) to increase survival times of patients with cirrhosis and refractory ascites. The high rate of shunt dysfunction with the use of uncovered stents counteracts the benefits of TIPS. We performed a randomized controlled trial to determine the effects of TIPS with stents covered with polytetrafluoroethylene in these patients. METHODS: We performed a prospective study of 62 patients with cirrhosis and at least 2 large-volume paracenteses within a period of at least 3 weeks; the study was performed at 4 tertiary care centers in France from August 2005 through December 2012. Patients were randomly assigned to groups that received covered TIPS (n = 29) or large-volume paracenteses and albumin as necessary (LVP+A, n = 33). All patients maintained a low-salt diet and were examined at 1 month after the procedure then every 3 months until 1 year. At each visit, liver disease-related complications, treatment modifications, and clinical and biochemical variables needed to calculate Child-Pugh and Model for End-Stage Liver Disease scores were recorded. Doppler ultrasonography was performed at the start of the study and then at 6 and 12 months after the procedure. The primary study end point was survival without a liver transplant for 1 year after the procedure. RESULTS: A higher proportion of patients in the TIPS group (93%) met the primary end point than in the LVP+A group (52%) (P = .003). The total number of paracenteses was 32 in the TIPS group vs 320 in the LVP+A group. Higher proportions of patients in the LVP+A group had portal hypertension-related bleeding (18% vs 0%; P = .01) or hernia-related complications (18% vs 0%; P = .01) than in the TIPS group. Patients in LVP+A group had twice as many days of hospitalization (35 days) as the TIPS group (17 days) (P = .04). The 1-year probability of remaining free of encephalopathy was 65% for each group. CONCLUSIONS: In a randomized trial, we found covered stents for TIPS to increase the proportion of patients with cirrhosis and recurrent ascites who survive transplantation-free for 1 year, compared with patients given repeated LVP+A. These findings support TIPS as the first-line intervention in such patients. ClinicalTrials.gov ID: NCT00222014.

Partial nephrectomy after selective embolization of tumor vessels in a hybrid operating room: A new approach of zero ischemia in renal surgery.

It is established that partial nephrectomy is the standard of care for tumors confined to the kidney. Achieving a partial nephrectomy without renal ischemia and limiting operative bleeding is the subject of numerous researches. Since 2010, hybrid operating rooms have been used to perform both interventional radiology and surgical procedures at the same place and time. We used this latest technology to treat 3 patients with localized kidney tumors. The tumors were of moderate complexity and all were treated after immediate hyperselective embolization by laparoscopic surgery without dissection and clamping of the renal pedicle. The embolization of tumor vessels could be performed using image-stitching software. After embolization, operative time was 50, 70 and 80 minutes and blood loss was less than 100 ml for each case. Postoperative control 3D arteriography confirmed the respect of the vascularization of the healthy renal parenchyma. No postoperative complications occurred. Combined approach including hyperselective embolization and partial nephrectomy in the same time in a dedicated operating room is a new approach of zero ischemia during partial nephrectomy which reduces the difficulty of the surgery, limits injury to the kidney and increases patient safety.
