RESUMO
INTRODUCTION: While thermal ablation is now a standard treatment option for oligometastatic colorectal cancer patients, selecting those who will benefit most from locoregional therapies remains challenging. This proof-of-concept study is the first to assess the feasibility of routine testing of ctDNA before and after thermal ablation with curative intent, analyzed by next-generation sequencing (NGS) and methylation specific digital droplet PCR (ddPCR). Our prospective study primary objective was to assess the prognostic value of ctDNA before thermal ablation. METHODS: This single-center prospective study from November 2021 to June 2022 included colorectal cancer patients referred for curative-intent thermal ablation. Cell-free DNA was tested at different time points by next-generation sequencing and detection of WIF1 and NPY genes hypermethylation using ddPCR. The ctDNA was considered positive if either a tumor mutation or hypermethylation was detected; recurrence-free survival was used as the primary endpoint. RESULTS: The study enrolled 15 patients, and a total of 60 samples were analyzed. The median follow-up after ablation was 316 days, and median recurrence-free survival was 250 days. CtDNA was positive for 33% of the samples collected during the first 24 h. The hazard ratio for progression according to the presence of baseline circulating tumor DNA was estimated at 0.14 (CI 95%: 0.03-0.65, p = 0.019). The dynamics are provided, and patients with no recurrence were all negative at H24 for ctDNA. DISCUSSION: This study shows the feasibility of routine testing of ctDNA before and after thermal ablation with curative intent. We report that circulating tumor DNA is detectable in patients with low tumor burden using 2 techniques. This study emphasizes the potential of ctDNA for discerning patients who are likely to benefit from thermal ablation from those who may not, which could shape future referrals. The dynamics of ctDNA before and after ablation shed light on the need for further research and larger studies.
RESUMO
Background Percutaneous CT-guided biopsy of lung nodules is an established method with high diagnostic accuracy but a high rate of pneumothorax and chest tube insertion compared with endobronchial methods. Purpose To investigate the effect of a protocol combining patient positioning biopsy-side down, needle removal during expiration, autologous blood patch sealing, rapid rollover, and pleural patching (PEARL) on complication rate after percutaneous CT-guided lung biopsy, especially chest tube insertion. Materials and Methods In a secondary analysis of both prospectively and retrospectively acquired data from December 2019 to November 2020, consecutive participants underwent biopsy with use of the PEARL protocol (prospective data) and were compared with patients who underwent biopsy at the same tertiary cancer center according to the standard method without any additional techniques (controls, retrospective data). Patient demographics, lesion characteristics, intraprocedural data, complications, and histologic results were recorded and compared. Results One hundred patients in the control group (mean age ± standard deviation, 63 years ± 12; 61 men) and 100 participants in the PEARL group (mean age, 64 years ± 12; 48 men) were evaluated. No differences were found in patient and lesion characteristics. The emphysema rate was 47 of 100 patients (47%) in both groups. The rate of pneumothorax was 37 of 100 patients (37%) in the control group versus 16 of 100 (16%) in the PEARL group (P = .001). Of the pneumothoraxes that occurred, fewer were during the intervention in the PEARL group, with 21 of 37 onsets (57%) in the control group versus three of 16 onsets (19%) in the PEARL group (P < .001). A chest tube was inserted in 13 of 100 patients (13%) in the control group and only in one of 100 (1%) in the PEARL group (P = .002). Histologic findings were diagnostic in 94 of 100 patients (94%) in the control group and 95 of 100 (95%) in the PEARL group (P > .99). Conclusion During CT-guided percutaneous lung biopsy, a protocol of positioning biopsy-side down, needle removal during expiration, autologous blood patch sealing, rapid rollover, and pleural patching, or PEARL, reduced rates of pneumothorax and chest tube insertion. © RSNA, 2021.

OBJECTIVES: Vertebral metastases with limited epidural extension (VMLEE) are frequently encountered in cancer patients; they can cause severe and debilitating symptoms including pain and neurological impairment and are usually treated by radiotherapy. In this study, we mainly evaluated the safety of combined local treatments (CLT), associating radiofrequency ablation (RFA) with vertebroplasty and radiotherapy (RT) to treat VMLEE. Also, we aimed to evaluate the short-term efficacy of CLT on bone metastases palliation and long-term prevention of skeletal-related events. METHODS: We retrospectively reviewed treatment complications, pain palliation, and skeletal complications after combined local treatments (CLT) for vertebral metastasis with limited epidural extension (VMLEE). RESULTS: Eighteen consecutive patients had CLT for 24 VMLEE, between June 2016 and January 2021. No major post-treatment complication was recorded. Nine patients had pain before the initiation of CLT. One month after CLT, only 3 patients had residual pain with a significant decrease of visual analogue scale (VAS), from 7.3 ± 2.4 to 2 ± 0 (p = .008), as well as the mean morphine milligram equivalent dose from 196.6 ± 135.7 to 38.5 ± 26, p = .008. Mean follow-up was 16.7 ± 11.5 months. Only one vertebra showed an increase of a preexisting vertebral fracture. Nine VMLEE had evidence of residual disease, including 2 which resulted in spinal cord compression (2, 11 months). CONCLUSION: CLT was safe and effective for pain palliation and long-term prevention of skeletal-related events for treatment of patients with VMLEE. The effectiveness of this combined treatment on tumor control and epidural involvement on the long term needs further investigation.

OBJECTIVES: Curative treatment of oligometastatic pulmonary disease aims at eradication of all metastases. Radiofrequency ablation (RFA) has been shown to be an efficient method and the frequency of local tumor progression (LTP) should be minimized. The objective of this study was to determine the morphological and treatment-related risk factors for LTP after RFA of pulmonary metastases. MATERIALS AND METHODS: All patients treated with RFA for pulmonary metastases from 2002 to 2014 were reviewed. All LTPs from 2011 to 2014 were individually matched on the basis of tumor size, number, and histology. In total, 48 LTPs and 112 controls were blindly analyzed for morphological factors including vicinity of bronchus and vessels as well as treatment-related factors such as the size of the ablation zone and ablation margins. RESULTS: In the simple regression analysis, the significant predictive variables were ≤ 5-mm distance to a large bronchus (OR = 4.94; p = 0.0095) or large vessel (OR = 7.09; p < 0.001), minimal ablation margin (≤ 5 mm (OR = 42.67; p < 0.001), and a central-peripheral ablation offset/ablation zone size > 0.36 (OR = 13.83; p = 0.013). In the multiple regression model, only a minimal ablation margin ≤ 5 mm remained a significant risk factor for LTP. CONCLUSION: Only the minimal ablation margin remains significant in the multiple regression analysis; the other factors are presumably surrogates of an insufficient ablation margin. Improvement of lung RFA outcomes can probably be obtained by immediate post RFA evaluation of ablation margins to ensure a minimal ablation margin of at least 5 mm. KEY POINTS: ⢠A distance < 5 mm to a bronchus or vessel of over 3 mm diameter is associated with insufficient ablation margin and thus risk factors for local tumor progression after pulmonary radiofrequency ablation. ⢠A minimal ablation margin of > 5 mm after pulmonary RFA is associated with significantly less local tumor progression and should be looked for at the end of treatment session before needle removal in order to decrease local tumor progression. ⢠Tumor location, pleural contact, occurrence of intra-alveolar hemorrhage, pulmonary atelectasis, and pneumothorax are not associated with an increased risk of local tumor progression.

Background Prophylactic image-guided procedures performed by interventional radiologists for impending pathologic fractures are becoming more pertinent, as patients with metastatic cancer have extended overall survival because of advanced therapies. Purpose To evaluate the efficacy, safety, and palliative durability of collimated-beam CT-guided percutaneous fixation with internal cemented screws (FICS) for impending pathologic fractures of the femoral neck. Materials and Methods This single-institute retrospective study examined all patients with metastatic cancer treated between February 2010 and October 2019 with collimated-beam CT-guided percutaneous FICS procedures for preventive consolidation of impending femoral neck pathologic fractures. The short-term palliative efficacy was assessed through comparison of visual analog scale (VAS) scores before and 1 month after FICS. A review of cross-section imaging and clinic reports identified any procedural complications. Long-term consolidation efficacy was defined as the absence of any screw dislodgement or development of a pathologic fracture at completion of the study. The Wilcoxon test was used for the mean comparison of paired nonparametric variables. Results Sixty-one consecutive patients (mean age, 59 years ± 11 [standard deviation]; 35 women) underwent preventive FICS for consolidation of impending pathologic femoral neck fracture with a mean follow-up of 533 days ± 689. Two patients died of cancer within the first month. Complications were limited to three self-resolving hematomas. The mean VAS score decreased 1 month after FICS from 4.2 ± 3.2 to 1.8 ± 2.0 (P < .001). The long-term consolidation efficacy was 92% (54 of 59 patients), with three of 59 patients (5%) subsequently developing fractures despite FICS and an additional two of 59 patients (3%) with durable FICS undergoing definitive total hip arthroplasty surgery because of local tumor progression. Conclusion Percutaneous fixation with internal cemented screws as performed by the interventional radiologist is a safe nonsurgical treatment that provides an effective palliative result and durable prevention for impending pathologic fractures of the femoral neck. © RSNA, 2020 Online supplemental material is available for this article.

PURPOSE: To assess the safety and efficacy of multilevel thoracolumbar vertebroplasty in the simultaneous treatment of ≥ 6 painful pathologic compression fractures. MATERIALS AND METHODS: Retrospective review was conducted of 50 consecutive patients treated with vertebroplasty for ≥ 6 pathologic compression fractures in a single session for pain palliation at a tertiary single cancer center from 2015 to 2019. Outcomes measured included procedural safety according to Common Terminology Criteria for Adverse Events (CTCAE), change in 4-week postprocedure back pain by numeric rating scale (NRS), comparison of daily opioid medication consumption, and development of skeletal-related events. RESULTS: A total of 397 pathologic compression fractures were treated during 50 sessions (mean, 7.9 per patient ± 1.5). Mean procedure duration was 162 minutes ± 35, mean postoperative hospitalization duration was 1.6 days ± 0.9, and mean follow-up duration was 401 days ± 297. Seven complications were recorded, including 1 case of symptomatic polymethyl methacrylate pulmonary embolism. No major complications (CTCAE grade 4/5) were reported. NRS pain score was significantly decreased (5.0 ± 1.8 vs 1.7 ± 1.4; P < .0001), with a mean score decrease of 3.3 points (66%). Opioid agent use decreased significantly (76 mg/24 h ± 42 vs 45 mg/24 h ± 37; P = .0003), with a mean decrease of 30 mg/24 h (39%). Skeletal-related events occurred in 7 patients (14%). CONCLUSIONS: Multilevel vertebroplasty for ≥ 6 pathologic compression fractures is safe and provides significant palliative benefit when performed simultaneously.

Purpose: To review the available options of percutaneous ablation of lung metastasis. Methods: General indications, prognostic factors, and image guidance of percutaneous lung ablations were reviewed. Specificities, technical aspects, advantages and limitations of each technic were highlighted. Complications and follow up where also reviewed. Results: Image-guided, percutaneous ablation is of interest for patients with a limit number (<3-5) small metastases (<2-3 cm). Other predictive factors have been reported such as the disease-free interval, the primary tumor, or the proximity with large vessels or bronchus. Radiofrequency ablation (RFA) is the most reported technic, with local control rate >90% for small tumors, and a very low complication rate. Microwave (MWA) and cryoablation are alternative technics developed in the last 15 years to overcome RFA limitations, with encouraging results. Larger ablations zones and less heat sink effect have been described with MWA. On the other hand, cryoablation allows painless treatments under conscious sedation and/or local anesthesia, high accessibility of difficult locations and promising results on prospective multicenter series. Although irreversible electroporation (IRE) could be used for lesions close to main blood vessels as it is not limited by the heat sink effect and does not have significant effects on connective tissue, allowing to treat lesions near to vital organs, preliminary results for lung metastasis are disappointing. Conclusion: Percutaneous ablation of lung metastases, whatever technic is used, is feasible, with high local control rate, and acceptable complication rate. Although indications seem clear enough, validation through controlled trials is mandatory.

Dedicated catheters for hepatic arterial infusion chemotherapy were removed from the market. The purpose of this study was to assess the results of a novel approach to overcome the shortage of dedicated catheters for hepatic arterial infusion chemotherapy in the treatment of colorectal cancer liver metastases. We retrospectively included patients who underwent a percutaneous placement of a hepatic intra-arterial port catheter in a single tertiary center from February 2021 to June 2022. We examined the patient baseline characteristics, technical features of the modified procedures, technical success rates, complications and oncological outcomes. Fourteen patients (median age: 60 years; q1 = 54; q3 = 70; range: 53-81 years) underwent 15 modified procedures. The main modification of our placement technique consisted of the use of an indwelling 5-Fr Vertebral catheter, on the tip of which we created a two-sided additional lateral hole. The catheter was connected to a pediatric port. The primary success rate was 100%, and the secondary success rate was 93.3%. There were two late major complications, graded IIIa according to the Clavien-Dindo classification. The median liver progression free survival was 6.1 months (q1 = 2.5; q3 = 7.2; range: 1.3-11.6). Our experience suggests that the derived utilization of the devices used routinely in interventional radiology provides an effective solution that can compensate for the shortage of dedicated devices.
RESUMO
RATIONALE AND OBJECTIVES: The long-term effectiveness of prostatic artery embolization (PAE) can be hampered by the recanalization of the previously embolized prostatic arteries (PA). The use of a liquid embolic agent (LEA) could limit this risk. The purpose of this study was to assess the safety and efficacy of repeat PAE (rePAE) using a LEA (Squid Peri) coupled with microspheres in patients experiencing recurring symptoms after initial embolization. MATERIALS AND METHODS: This retrospective single-center study included all consecutive patients who underwent rePAE using Squid Peri coupled with microspheres. Angiographic patterns of prostatic revascularization were identified. Outcomes were assessed at the 3-month follow-up using the International Prostate Symptom Score (IPSS) and the Quality of Life (QoL) score. The primary endpoint was clinical success defined as an IPSS < 18 with > 25% decrease and a QoL score ≤ 3 with ≥ 1 point decrease. Safety was assessed by using the modified Clavien-Dindo classification. RESULTS: 30 consecutive men (mean age: 67.1 ± 9.5 years) were included. Recanalization of the previously embolized PA was found in 83.3% of patients. Technical success was 93.3%. Median follow-up was 4.9 months [IQR: 3.9 - 9.8]. Clinical success rate was 76.7%, with a mean decrease in IPSS of -9.3 ± 7.3 (p < 0.001) and a median decrease in QoL of -2 [IQR: - 4 - - 1] (p < 0.001). One patient presented with an acute urinary retention requiring readmission (grade IIIa complication). CONCLUSION: Repeat PAE using Squid Peri coupled with microspheres is safe and effective for patients with recurring symptoms after initial embolization.
RESUMO
OBJECTIVES: To evaluate the benefits of repeat prostatic artery embolization (rePAE) for patients with persistent or recurrent symptoms after initial prostatic artery embolization (PAE). MATERIALS AND METHODS: This is a single-center retrospective study of all patients who underwent a rePAE between December 2014 and November 2020 for persistent or recurrent lower urinary tract symptoms. Symptoms were assessed before and after PAE and rePAE, using the International Prostate Symptom Score and quality of life (QoL) questionnaires. Patient characteristics, anatomical presentations, technical success rates, and complications of both procedures were collected. Clinical failure was defined as one of the following: less than 2 points' decrease in QoL, a QoL score higher than 3, acute urinary retention, and secondary surgery. RESULTS: A total of 21 consecutive patients (mean age: 63.8 ± 8.1; [40-75] years) who underwent rePAE were included. The median follow-up after PAE was 27.7 [18.1-36.9]) months and 8.9 [3.4-10.8] months after rePAE. rePAE was performed at a mean of 19 ± 11.1 [6.9-49.6] months following PAE, and the overall clinical success rate was 33% (7/21). In patients undergoing rePAE because of persistent symptoms, the clinical success rate (18%) was non-significantly lower than that for patients treated for recurrent symptoms (50%) [OR 4.5 (95% CI 0.63-32 P = 0.13)]. The main anatomical revascularization pattern was recanalization of the native prostatic artery (29/45, 66%). CONCLUSION: Patients who experience recurrent symptoms after PAE may benefit more from rePAE than those with persistent symptoms after PAE. Clinical success rates seem to be relatively low in both clinical scenarios.

Purpose To evaluate the efficacy, durability, and safety of percutaneous fixation by internal cemented screw (FICS) for prophylactic consolidation of impending pathologic fractures of the pelvic ring. Materials and Methods In this single-institute retrospective study, patients with large, minimally symptomatic to asymptomatic osteolytic tumors of the pelvic ring that were treated with percutaneous cone-beam CT-guided FICS procedures were included (January 2014 to May 2019). Follow-up cross-section imaging and clinical reports were reviewed for procedural complications and assessment of the long-term consolidation efficacy on the basis of the development of pathologic fracture or need for additional surgical intervention. All continuous variables were expressed as a mean with standard deviation, and dichotomous variables were expressed as frequencies and percentages. Results Fifty consecutive patients (mean age, 60 years ± 12; 27 men) underwent prophylactic FICS for consolidation of 54 osteolytic tumors (mean size, 51 mm ± 21.5; range, 30-114 mm). Local tumor destruction was performed in association with FICS in 38 patients (76%) using percutaneous thermal and/or radiation therapy. Follow-up exceeded a year in 35 patients (70%), with mean follow-up of 22 months ± 18 (range, 1-67 months). Long-term consolidation efficacy was 98% (49 of 50), with the development of a pathologic fracture in only one patient 20 months after FICS. Procedural complications were limited to two patients with self-resolving hematoma, one patient with inflammatory sciatic pain, and one patient with focal pain at the ischial tuberosity. Conclusion Percutaneous FICS provides a safe and durable minimally invasive treatment for the prevention of pathologic fractures of the pelvic ring.

Interventional oncology and the value of thermal ablation of small tumors is increasingly recognized by the oncological community. Primary lung cancers and lung metastases have been one of the most researched applications of percutaneous ablation and as interventional oncologists gain more experience and confidence, it is becoming a more effective treatment with expanding indications. Importantly, the current literature does not demonstrate major differences in survival between ablation, sublobar resection, and stereotactic body radiation. The advantages of percutaneous ablation over other local therapies like surgery or SBRT are significantly lower morbidity, mortality, and repeatability of treatments. The focus of this essay is to highlight technical and procedural aspects of lung ablation as well as management and follow-up in a practical fashion.

PURPOSE: To assess safety and efficacy of multi-level vertebroplasty, when treating 6 or more levels in the same procedural setting for the management of osteoporotic vertebral compression fractures (oVCF) in cancer patients. MATERIALS AND METHODS: Single institution retrospective review from 2015 to 2019 of patients treated for multi-level oVCF in a single session procedural setting by vertebroplasty of 6 or more levels. Procedure outcomes collected included procedural complications, pre- and 4 week post-procedure pain score by numeric rating scale, opioid usage, and vertebral height changes. RESULTS: In total, 197 vertebral levels were treated in 24 procedures (mean 8.2 ± 1.8 levels). Mean procedure duration was 167 + / - 41 min, and mean postoperative hospitalization duration was 2.1 + / - 1.9 days. Four grade I or II complications occurred according to CIRSE classification. Two patients had a symptomatic pulmonary cement embolism; although there was no statistical difference between pre- and postoperative mean blood saturation (95.9 + / - 1.7% and 94.8 + / - 2.0%, respectively, p = 0.066). Pain score significantly improved after treatment (6.5 ± 1.3 vs 3.2 + / - 1.4, p < 0.0001) with a mean decrease of 3.3 (51%). Post-procedure daily opioid use also significantly improved (mean 35.8 + / - 36.8 mg/24 h vs 18.5 + / - 27.8 mg/24 h, p = 0.0089), with a mean decrease of 17.3 mg/24 h (48%). Refracture was found in 2 of 105 levels treated (1.9%), and no difference was found in thoraco-lumbar height and angulation. Five patients experienced new painful fractures at a non-treated level. CONCLUSION: Multi-level vertebroplasty for 6 or more levels is a safe and effective treatment for the management of multi-level oVCF in cancer patients.

RESUMO
PURPOSE: To evaluate the feasibility, efficacy and safety of sternal percutaneous fixation by internal cemented screw (FICS) using fluoroscopy and/or CT needle guidance. MATERIALS AND METHODS: This retrospective single-center study analyzed 9 consecutive cancer patients managed with percutaneous FICS for sternal fracture fixation or osteolytic metastasis consolidation, from May 2014 to February 2019. Eastern Cooperative Oncology Group performance status, Numeric Pain Rating Scale (NPRS) and opioid use were studied preoperatively and postoperatively. Sternal images at last follow-up appointment were also collected. RESULTS: Among the 9 patients, 7 had a sternal fracture with 5 being displaced. The technical feasibility was 100%. Both NPRS score significantly decreased from 5.6/10 ± 2.8 to 1.1/10 ± 1.6, and analgesic consumption was significantly improved (p = 0.03) after intervention. No post-procedural complications requiring surgical correction or screw displacement occurred after a mean imaging follow-up that exceeded 1 year (mean follow-up duration, 401.8 days ± 305.8). CONCLUSION: Image-guided sternal percutaneous FICS is feasible and safe. It reduces pain and analgesic consumption related to pathologic fracture of the sternum.

PURPOSE: We aimed to identify modifiable and nonmodifiable risk factors for hemoptysis complicating computed tomography (CT)-guided transthoracic needle biopsy. METHODS: All procedures performed in our institution from November 2013 to May 2015 were reviewed. Hemoptysis was classified as mild if limited to hemoptoic sputum and abundant otherwise. Presence of intra-alveolar hemorrhage on postbiopsy CT images was also evaluated. Patient- and lesion-related variables were considered nonmodifiable, while procedure-related variables were considered modifiable. RESULTS: A total of 249 procedures were evaluated. Hemoptysis and alveolar hemorrhage occurred in 18% and 58% of procedures, respectively, and were abundant or significant in 8% and 17% of procedures, respectively. Concordance between the occurrence of significant alveolar hemorrhage (grade ≥2) and hemoptysis was poor (κ=0.28; 95% CI [0.16-0.40]). In multivariate analysis, female gender (P = 0.008), a longer transpulmonary needle path (P = 0.014), and smaller lesion size (P = 0.044) were independent risk factors for hemoptysis. Transpulmonary needle-path length was the only risk factor for abundant hemoptysis with borderline statistical significance (P = 0.049). CONCLUSION: The transpulmonary needle path should be as short as possible to reduce the risk of abundant hemoptysis during CT-guided transthoracic needle biopsy.
