[PMID: 38658897 PMCID: PMC11040968 DOI: 10.1186/s12890-024-03012-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 04/12/2024] [Indexed: 04/26/2024] Open
Abstract
PURPOSE To summarize and analyze the safety and efficacy of a Y-shape Sigma stent loaded with I125 in patients with inoperable malignant main airway obstruction. METHODS This study was approved by the Institutional Ethics Committee, and a written informed consent was obtained from each participant. A Y-shape Sigma stent loaded with I125 was placed under vision from rigid bronchoscopy. The primary endpoint was alleviation of symptoms and improvement of Karnofsky Performance Status (KPS) score, and the secondary endpoint was complications and technical success. RESULTS From November 2018 through June 2023, total 33 patients with malignant airway obstruction were palliatively treated by installing Y-shape Sigma stents loaded with I125. The airway lumen was immediately restored and the average airway opening significantly increased to 70 ± 9.4% after the procedure from baseline 30.2 ± 10.5% (p < 0.05). Average KPS score was improved from baseline 30.0 ± 10.0 to 70.0 ± 10.0 (p < 0.05) as well as PaO2 from baseline 50.1 ± 15.4 mmHg to 89.3 ± 8.6 mmHg (p < 0.05). The technical success rate of placing the stent in this study was 73%, and adverse events or complications including bleeding, I125 loss, and airway infection occurred during or after the procedure. CONCLUSION Placement of Y-shape Sigma stents under vision from rigid bronchoscopy in the patients with malignant airway obstruction is feasible and it immediately alleviates dyspnea and significantly improves quality of life.

Local hyperthermia mediated by gold nanoparticle-integrated silicone-covered stent: feasibility and tissue response in a rat esophageal model. Eur Radiol Exp 2024; 8:40. [PMID: 38565836 PMCID: PMC10987532 DOI: 10.1186/s41747-024-00438-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 01/16/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND To assess the feasibility and tissue response of using a gold nanoparticle (AuNP)-integrated silicone-covered self-expandable metal stent (SEMS) for local hyperthermia in a rat esophageal model. METHODS The study involved 42 Sprague-Dawley rats. Initially, 6 animals were subjected to near-infrared (NIR) laser irradiation (power output from 0.2 to 2.4 W) to assess the in vitro heating characteristics of the AuNP-integrated SEMS immediately after its placement. The surface temperature of the stented esophagus was then measured using an infrared thermal camera before euthanizing the animals. Subsequently, the remaining 36 animals were randomly divided into 4 groups of 9 each. Groups A and B received AuNP-integrated SEMS, while groups C and D received conventional SEMS. On day 14, groups A and C underwent NIR laser irradiation at a power output of 1.6 W for 2 min. By days 15 (3 animals per group) or 28 (6 animals per group), all groups were euthanized for gross, histological, and immunohistochemical analysis. RESULTS Under NIR laser irradiation, the surface temperature of the stented esophagus quickly increased to a steady-state level. The surface temperature of the stented esophagus increased proportionally with power outputs, being 47.3 ± 1.4 °C (mean ± standard deviation) at 1.6 W. Only group A attained full circumferential heating through all layers, from the epithelium to the muscularis propria, demonstrating marked apoptosis in these layers without noticeable necroptosis. CONCLUSIONS Local hyperthermia using the AuNP-integrated silicone-covered SEMS was feasible and induced cell death through apoptosis in a rat esophageal model. RELEVANCE STATEMENT A gold nanoparticle-integrated silicone-covered self-expanding metal stent has been developed to mediate local hyperthermia. This approach holds potential for irreversibly damaging cancer cells, improving the sensitivity of cancer cells to therapies, and triggering systemic anticancer immune responses. KEY POINTS • A gold nanoparticle-integrated silicone-covered self-expanding metal stent was placed in the rat esophagus. • Upon near-infrared laser irradiation, this stent quickly increased the temperature of the stented esophagus. • Local hyperthermia using this stent was feasible and resulted in cell death through apoptosis.

A Functional Stent Encapsulating Radionuclide in Temperature-Memory Spiral Tubes for Malignant Stenosis of Esophageal Cancer. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2023; 35:e2307141.

Abstract
Stent implantation is a commonly used palliative treatment for alleviating stenosis in advanced esophageal cancer. However, tissue proliferation induced by stent implantation and continuous tumor growth can easily lead to restenosis. Therefore, functional stents are required to relieve stenosis while inhibiting tissue proliferation and tumor growth, thereby extending the patency. Currently, no ideal functional stents are available. Here, iodine-125 (125 I) nuclides are encapsulated into a nickel-titanium alloy (NiTi) tube to develop a novel temperature-memory spiral radionuclide stent (TSRS). It has the characteristics of temperature-memory, no cold regions at the end of the stent, and a uniform spatial dose distribution. Cell-viability experiments reveal that the TSRS can reduce the proliferation of fibroblasts and tumor cells. TSRS implantation is feasible and safe, has no significant systemic radiotoxicity, and can inhibit in-stent and edge stenosis caused by stent-induced tissue proliferation in healthy rabbits. Moreover, TSRS can improve malignant stenosis and luminal patency resulting from continuous tumor growth in a VX2 esophageal cancer model. As a functional stent, the TSRS combines the excellent properties of NiTi with brachytherapy of the 125 I nuclide and will make significant contributions to the treatment of malignant esophageal stenosis.

[PMID: 37599156 DOI: 10.1016/j.brachy.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 05/11/2023] [Accepted: 05/16/2023] [Indexed: 08/22/2023]
Abstract
PURPOSE To investigate the safety and efficacy of iodine-125 seed implantation in the treatment of abdomen-thorax desmoid tumors (DTs). METHODS AND MATERIALS Data from 14 DT patients who received brachytherapy with iodine-125 seeds were retrospectively collected from 2014 to 2020. The operation was completed using CT guidance and the treatment plan system (TPS). The number of lesions and the target dosimetry parameters were recorded. After brachytherapy, the lesions were evaluated using response evaluation criteria in solid tumors (RECIST). RESULTS Fourteen patients with 18 lesions were enrolled in this study; eleven lesions were in the thorax, seven were in the abdomen, and the lesion gross tumor volume (GTV) was 82.10 cc (interquartile range [IQR]: 40.37, 203.42 cc). The median number of seeds was 88 (IQR: 35, 158), and the median prescription dose was 120 Gy (IQR: 115, 120 Gy). The D90 was 123 ± 16.7 Gy, the V90 was 97% (IQR: 95.00, 97.25%), and the V200 was 27% (IQR: 14.50, 33.00%). The median follow-up time for each lesion was 34 (IQR: 23, 67) months, and the local response rate was 100%. Following brachytherapy, the overall survival was 52.3 ± 30.72 months. One year after brachytherapy, one patient experienced persistent worsening of a brachial plexus injury; another received a ureteral stent. No brachytherapy-related complications were observed in the remaining patients. CONCLUSIONS Iodine-125 brachytherapy is a novel treatment option for DT of the abdomen and thorax. Although it is a safe and effective treatment, the radiation dose of iodine-125 brachytherapy for DT-embedded organs at risk must be investigated further.

Abstract
OPINION STATEMENT Esophageal cancer is a global health problem, which is 7th most common and 6th most deadly cancer. It has been the era of immuno-oncology for esophageal cancer management. Radiation therapy has been one of the key local therapeutic approaches for esophageal cancer treatment, while its role in advanced disease is challenging and debatable. There have been emerging clinical and translational studies of radiation therapy in recurrent or metastatic esophageal cancer. Immunotherapy has been established the standard care of 1st and 2nd line systemic therapies of advanced esophageal cancer, and the development of tumor immunity has opened a new chapter for the esophageal cancer radiation therapy. The current review will summarize the classic radiation therapy research in advanced esophageal cancer, as well as the most recent key findings. The subtitles will cover palliative radiotherapy for dysphagia, re-radiation for recurrent disease, oligo-focal disease management and stereotactic radiation therapy, and radiotherapy with immunotherapy. Radiotherapy plays vital role in multidisciplinary management of advanced EC. External or intratumoral irradiation has been used for palliation of dysphagia and improving QOL in esophageal cancer patients traditionally, while recent clinical and technical advance enables radiotherapy to be considered in recurrent or metastatic disease for curation attention. Novel clinical and translational investigation is opening a new chapter of radiotherapy with immunotherapy for benefiting advanced EC patients.

Ishihara R. Endoscopic Stenting for Malignant Dysphagia in Patients with Esophageal Cancer. Curr Oncol 2023; 30:5984-5994.

Abstract
Malignant dysphagia is a common problem in patients with esophageal cancer. Endoscopic stenting can resolve dysphagia caused by malignant stricture; however, controversy exists regarding the use of esophageal stenting for the treatment of malignant stricture, including whether stenting or radiotherapy is superior, whether stenting before or after radiotherapy is safe, whether stenting before or after chemotherapy is safe, and whether low-radial-force stents are safer than conventional stents. Among treatment options for malignant dysphagia, stenting may have some disadvantages in terms of pain relief and the risk of adverse events compared with radiotherapy and in terms of survival compared with gastrostomy. Additionally, the risk of stent-related adverse events is significantly associated with prior radiotherapy. The risk of perforation is especially high when a radiation dose of >40 Gy is delivered to the esophagus after stenting, whereas perforation is not associated with prior chemotherapy or additional chemotherapy after stenting. Nevertheless, stenting remains an important palliative option, especially for patients with a short life expectancy and a strong desire for oral intake, because stenting can facilitate a more rapid improvement in dysphagia than radiotherapy or gastrostomy. The application of a low-radial-force stent should be considered to reduce the risk of adverse events, especially in patients with prior radiotherapy.

Abstract
Introduction Hepatocellular carcinoma (HCC) has very poor prognosis due to its immunosuppressive properties. An effective measure to regulate tumor immunity is brachytherapy, which uses 125I seeds planted into tumor. T cell immune receptors with immunoglobulin and ITIM domains (TIGIT) is highly expressed in HCC. The TIGIT-targeted probe is expected to be an effective tool for indicating immunomodulation of 125I seed brachytherapy in HCC. In this study, We constructed a novel peptide targeting TIGIT to evaluate the immune regulation of 125I seed brachytherapy for HCC by near-infrared fluorescence (NIRF). Methods Expression of TIGIT by immunofluorescence (IF) and flow cytometry (FCM) in different part and different differentiated human liver cancer tissues was verified. An optical fluorescence probe (Po-12) containing a NIRF dye and TIGIT peptide was synthesized for evaluating the modulatory effect of 125I seed brachytherapy. Lymphocytes uptake by Po-12 were detected by FCM and confocal microscopy. The distribution and accumulation of Po-12 in vivo were explored by NIRF imaging in subcutaneous and orthotopic tumors. IHC and IF staining were used to verify the expression of TIGIT in the tumors. Results TIGIT was highly expressed in HCC and increased with tumor differentiation. The dye-labeled peptide (Po-12) retained a stable binding affinity for the TIGIT protein in vitro. Accumulation of fluorescence intensity (FI) increased with time extended in subcutaneous H22 tumors, and the optimal point is 1 h. TIGIT was highly expressed on lymphocytes infiltrated in tumors and could be suppressed by 125I seed brachytherapy. Accumulation of Po-12-Cy5 was increased in tumor-bearing groups while declined in 125I radiation group.

Abstract
BACKGROUND The purpose of this study was to explore the feasibility, safety and efficacy of iodine-125 seed implantation in the treatment of dysphagia of advanced esophageal cancer. METHODS We retrospectively analyzed patients with advanced esophageal cancer who underwent EUS-guided iodine-125 seed implantation or conventional chemoradiotherapy in our hospital. The propensity score match was used to reduce the baseline differences. RESULTS A total of 127 patients were enrolled, 17 patients received EUS-guided iodine 125 seed implantation (Group A), 31 patients received radiotherapy (Group B), 38 patients received chemotherapy (Group C) and 41 patients received chemotherapy combined with radiotherapy (Group D). At half month postoperatively, the dysphagia remission rate in Group A (100%) was better than that in Groups B (39.3%), C (20%), D (15.8%), respectively, in the original cohort (P < 0.01); At 1 month postoperatively, the dysphagia remission rate in Group A (86.7%) was better than that in Group B (57.1%) (P > 0.05), Group C (25.7%) (P < 0.05) and Group D (34.2%) (P < 0.05), respectively, in the original cohort. There was no statistically significant difference in median overall survival (OS) between Group A (16 months) and Group B (37 months) (P = 0.149), and between Group A (16months) and Group C (16 months) (P = 0.918) in the original cohort. The mean OS of Group D (54 months) was better than that of Group A (20 months) in the original cohort (P = 0.031). The incidences of grade ≥2 myelosuppression in Groups B, C, and D were 12.9%, 28.9%, and 43.9%, respectively; the incidence of grade ≥2 gastrointestinal adverse events in Groups B, C, and D were 12.9%, 15.8%, 12.2%, respectively. No serious adverse events were found in Group A. The radiation dose around the patient was reduced to a safe range after the distance from the implantation site was more than 1 m (4.2 ± 2.6 μSv/h) or with lead clothing (0.1 ± 0.07 μSv/h). CONCLUSIONS Compared with conventional radiotherapy or chemotherapy alone, iodine-125 seed implantation might improve dysphagia more quickly and safely, further clinical data is needed to verify whether it could effectively prolong the OS of patients.

Abstract
The majority of patients with esophageal cancer are diagnosed at an advanced, incurable stage. Palliation of symptoms, specifically dysphagia, is a crucial component to improve quality of life and optimize nutritional status. Despite multiple available treatment modalities, there is not one accepted or recommended to be the preferred treatment option. Palliative management is often decided by a multidisciplinary team considering factors including local availability, preference, patient life expectancy, and symptom severity. Systemic therapies such as chemotherapy are the most commonly used palliative modalities. Oncologists are most familiar with radiation for dysphagia palliation, especially for advanced metastatic cancer patients with good performance status. One common approach used by endoscopist is self-expandable metal stents. This is preferred for patients with short-term survival and poor functional status as it provides rapid relief of dysphagia. Cryotherapy is a relatively new endoscopic ablative modality and appears to be a promising option for dysphagia palliation, but more data is needed for wider adoption. This review summarizes the current literature on endoscopic and non-endoscopic treatment options for malignant dysphagia.

Abstract
PURPOSE Brachytherapy is most often applied in the curative or salvage setting, but many forms of brachytherapy can be helpful for symptom palliation. Declining utilization is seen, for multiple reasons, such as lack of awareness, insufficient expertise, or poor access to equipment. High level evidence for many types of palliative brachytherapy has been lacking. The objective of the current study was to review the evidence for utilization and efficacy of brachytherapy to palliate symptoms from cancer. MATERIALS AND METHODS We performed a systematic search in EMBASE and MEDLINE for English-language articles published from January 1980 to May 2022 that described brachytherapy used for a palliative indication in adults with a diagnosis of cancer (any subtype) and at least one symptom related outcome. Individual case reports and conference abstracts were excluded. All publications were independently screened by two investigators for eligibility. RESULTS The initial search identified 3637 abstracts of which 129 were selected for in-depth review. The number of studies (total number of patients) included in the final analysis varied widely by tumor site with the majority (68.2%) involving either lung or esophageal cancer. Despite a limited number of prospective trials that assessed the efficacy of brachytherapy for symptom management, there was a positive effect on palliation of symptoms across all tumor types. There was no clear trend in the number of publications over time. The most commonly cited symptom indications for palliation by brachytherapy were dysphagia, dyspnea, pain and bleeding. CONCLUSIONS Brachytherapy can provide palliation for patients with advanced cancer, across different tumor sites and clinical scenarios. However, high level evidence in the literature to support palliative applications of brachytherapy is lacking or limited for many tumor sites. There appears to be a strong publication bias towards positive studies in favor of brachytherapy. Beyond anecdotal reports and individual practices, outcomes research can further our understanding of the role of brachytherapy in palliating advanced cancers of all types, and should be encouraged.

Abstract
ObjectiveTo evaluate the dosimetric characteristics and the clinical application of radioactive iodine-125 brachytherapy stent (RIBS) in malignant esophageal obstruction.MethodsThe dose distribution of RIBS with different seed spacing, diameter and length was studied by treatment planning system (TPS) calculation, thermoluminescence dosimeter (TLD) measurement and Monte Carlo (MC) data fitting. And the data of esophageal cancer patients who were treat with this type of RIBS was analyzed retrospectively.ResultsDoses around the RIBS calculated by the TPS lay between those measured by the TLDs and those simulated by the MC, and the differences between the three methods were significant (p<0.05), the overall absolute dose differences among the three methods were small. Dose coverage at 1.5 cm from the center was comprehensive when the activity reached 0.6 mCi. Both the conformability and the uniformity of isodose lines produced by a seed spacing of 1.0 cm were superior to those produced by a seed spacing of 1.5 cm. The data of 50 patients treated with RIBS was analyzed. They were followed up until February 2020 when all of the patients died. The overall improvement rate of dysphagia after RIBS implant was 90%. Moderate and severe complications with an incidence of more than 10% were hematemesis (28%), pain (20%), and lung infection (10%). Stent restenosis occurred in 4 patients at a median interval of 108 days from the procedure. The overall incidence of fatal complications was 38% (including hematemesis, infection and asphyxia). The median survival time of patients with and without a history of radiotherapy were 3.4 months and 6 months, respectively, the difference of which was significant (p=0.021). No other factors affecting survival were identified. For patients with and without a history of radiotherapy, the incidences of fatal complications were 51.7% and 19%, respectively (p=0.019). No correlation between dose and stent restenosis was found.ConclusionTPS calculations are suitable for clinical applications. RIBS can effectively alleviate obstructive symptoms for patients with malignant esophageal obstruction, but the incidence of fatal complications was high, care should be taken when choosing this treatment.

Abstract
Fluoroscopic-guided stent placement has become an advantageous treatment option for diverse gastrointestinal disorders. In addition to palliative stent placement in patients with inoperable cancers, stenting has gradually expanded to other conditions, including as a bridge to surgery, as well as in patients' benign lesions and anastomotic strictures or leaks. This narrative review describes the indications, efficacy and safety of stent placement from the esophagus to the colon, including current recommendations, recent updates, and novel stents.

Abstract
125I seeds can effectively inhibit the growth of a variety of cancer cells. It has been used in the treatment of a variety of cancers, and has achieved certain curative effect. However, to the best of our knowledge, no report has described the effects of 125I seeds on the biological functions of cholangiocarcinoma (CCA) and the mechanisms underlying the effects of the seeds on this cancer. In this study, we demonstrated that 125I seeds could inhibit the proliferation, migration and invasion of CCA cells, as well as promoting apoptosis and blocking the cell cycle in these cells. Moreover, 125I seeds inhibited the growth of CCA xenografts and promoted the apoptosis of CCA cells in vivo. Furthermore, transcriptome sequencing showed that 125I seeds could inhibit the growth of CCA by inhibiting the expression of AGR2 and regulating p38 MAPK pathway. Finally, this finding indicated that 125I seeds can inhibit proliferation and promote apoptosis in CCA cells by inhibiting the expression of AGR2 and DUSP1 and increasing the expression of p-p38 MAPK and p-p53. This study provides a new research direction for studies investigating the mechanisms underlying the effects of 125I seeds on CCA.

Abstract
Introduction Malignant esophageal obstruction is usually caused by esophageal and other chest cancers. More than 80% of cases of obstructive esophageal cancer (OEC) have lost the chance of curative resection. Stent insertion is a first-line palliative approach used to treat incurable OEC. Aim To gauge the relative clinical efficacy of I-125 seed-loaded stent (ISS) versus normal stent (NS) insertion as a treatment for OEC. Material and methods Querying of the PubMed, Embase, and Cochrane Library databases was conducted to find all relevant studies published up to November 2020. The meta-analysis was undertaken using RevMan v5.3. Results We identified 158 studies initially, eight (4 randomized controlled trials and 4 retrospective studies) of which were used in this meta-analysis. We found that the two groups exhibited the comparable pooled Δdysphagia scores (MD = 0.02; p = 0.80), stent restenosis rates (OR = 0.97; p = 0.89), stent migration rates (OR = 0.81; p = 0.63), severe chest pain rates (OR = 1.05; p = 0.81), hemorrhage rates (OR = 1.53; p = 0.16), aspiration pneumonia rates (OR = 0.72; p = 0.38), and fistula formation rates (OR = 1.47; p = 0.44). The pooled time-to-restenosis and survival were both significantly longer in the ISS group (p = 0.04 and < 0.0001, respectively). Significant heterogeneity was detected in the endpoints of Δdysphagia scores and survival (I2 = 73% and 86%, respectively). Funnel plot analysis indicated an absence of publication bias related to the selected study endpoints. Conclusions For patients with OEC, our meta-analysis indicated that ISS insertion could provide longer stent patency and survival than NS insertion.

Abstract
We aimed to compare available palliative treatments in terms of survival and to rank these treatments for esophageal cancer. Web of Science, Medline, Scopus, Cochrane Library and Embase were searched. The risk of bias was judged using Cochrane's tools. Statistical heterogeneity was assessed using the Chi2 test and was quantified by I2. The results were summarized using the hazard ratio (HR). The rank probability for each treatment was calculated using the p-score. Nineteen RCTs met the eligibility criteria for this study. Treatments formed three networks including networks A, B, and C. The Ultraflex stent (p-score = 0.93), irradiation stent (p-score = 0.89), and thermal ablative therapy (p-score = 0.85) were the first ranking treatments in networks A, B, and C, respectively. Based on the results of this network meta-analysis, it appears that the ultraflex stent, the irradiation stent, and thermal ablative therapy are the better treatments among the networks.

Abstract
Radioactive iodine-125 (I-125) is the most widely used radioactive sealed source for interstitial permanent brachytherapy (BT). BT has the exceptional ability to deliver extremely high doses that external beam radiotherapy (EBRT) could never achieve within treated lesions, with the added benefit that doses drop off rapidly outside the target lesion by minimizing the exposure of uninvolved surrounding normal tissue. Spurred by multiple biological and technological advances, BT application has experienced substantial alteration over the past few decades. The procedure of I-125 radioactive seed implantation evolved from ultrasound guidance to computed tomography guidance. Compellingly, the creative introduction of 3D-printed individual templates, BT treatment planning systems, and artificial intelligence navigator systems remarkably increased the accuracy of I-125 BT and individualized I-125 ablative radiotherapy. Of note, utilizing I-125 to treat carcinoma in hollow cavity organs was enabled by the utility of self-expandable metal stents (SEMSs). Initially, I-125 BT was only used in the treatment of rare tumors. However, an increasing number of clinical trials upheld the efficacy and safety of I-125 BT in almost all tumors. Therefore, this study aims to summarize the recent advances of I-125 BT in cancer therapy, which cover experimental research to clinical investigations, including the development of novel techniques. This review also raises unanswered questions that may prompt future clinical trials and experimental work.

Abstract
BACKGROUND Malignant obstructive jaundice is mainly caused by cholangiocarcinoma. Only a few patients are indicated for surgical resection, and the 3-year survival rate is < 50%. For patients who are not eligible for surgery, biliary stent placement can relieve biliary obstruction and improve liver function and quality of life. However, restenosis after biliary stents has a poor prognosis and is a clinical challenge. Biliary stent combined with iodine-125 (125I) seed implantation can prolong stent patency and improve survival.
AIM To evaluate the safety and efficacy of biliary stent combined with 125I seed strand implantation in malignant obstructive jaundice.
METHODS We enrolled 67 patients between January 2016 and June 2018 with malignant obstructive jaundice and randomized them into a biliary stent combined with 125I seed strand treatment (combined) group (n = 32) and biliary stent (control) group (n = 35). All patients underwent enhanced computed tomography and magnetic resonance imaging and were tested for biochemical and cancer markers. Twelve patients underwent pathological examination before surgery. All patients were followed up by telephone or clinical visit. Postoperative liver function improvement, postoperative complications, stent patency time, and survival time were compared between the two groups. Prognostic risk factors were evaluated.
RESULTS Technical success was achieved in all patients in both groups. Postoperative liver function improved significantly in all patients (total bilirubin, direct bilirubin, alanine aminotransferase, and aspartate aminotransferase decreased significantly in all patients, the P values were less than 0.05). There was no significant difference in preoperative or postoperative indexes between the two groups for changes in total bilirubin (P = 0.147), direct bilirubin (P = 0.448), alanine aminotransferase (P = 0.120), and aspartate aminotransferase (P = 0.387) between the two groups. The median stent patency time of the combined group was 9.0 ± 1.4 mo [95% confidence interval (CI): 6.3-11.8 mo], which was significantly longer than the that of the control group (6.0 ± 0.3 mo, 95%CI: 5.5-6.5 mo, P = 0.000). The median survival time of the combined group was 11.0 ± 1.4 mo (95%CI: 8.2-13.7 mo), which was significantly longer than that of the control group (7.0 ± 0.3 mo, 95%CI: 6.4-7.6 mo, P = 0.000). Location of obstruction and number of stents were independent risk factors affecting prognosis.
CONCLUSION Biliary stent combined with 125I seed strand implantation is safe and effective in malignant obstructive jaundice and improves stent patency time and median survival time.

[PMID: 33455874 DOI: 10.1016/j.canrad.2020.12.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 11/10/2020] [Accepted: 12/14/2020] [Indexed: 02/06/2023]
Abstract
PURPOSE A meta-analysis aimed to systematically evaluate the safety and efficiency of I125 irradiation stent placement for patients with hepatocellular carcinoma (HCC) combined with portal vein tumor thrombosis (PVTT). MATERIALS AND METHODS The Cochrane library, PubMed/Medline, EMBASE, CNKI, Wanfang Data and CQVIP were systematically screened out from the earliest to December 2019. The qualities of all included studies were assessed. The primary endpoints were the 6-month, 12-month stent cumulative patency rate and 6-month, 12-month, 24-month overall survival rate while the secondary endpoints were the objective response rate of PVTT, main portal venous pressure changes and treatment-related adverse events. Our meta-analysis was conducted using Stata 12.0 software. RESULTS Totally seven studies with 1018 patients were included in the final analysis, in which 602 patients received TACE and I125 irradiation stent placement, and 416 patients in control group underwent TACE and stent placement without endovascular brachytherapy (EVBT). Meta-analysis showed that the I125 irradiation stent improved the cumulative stent patency rates in 6months [OR=1.65, 95% CI (1.32-2.05), P<0.001] and 12months [OR=2.55, 95% CI (1.90-3.42), P<0.001] and the survival rates in 6months [OR=1.77, 95% CI (1.41-2.22), P<0.001], 12months [OR=3.14, 95% CI (2.24-4.40), P<0.001] and 24months [OR=7.39, 95% CI (3.55-15.41), P<0.001]. However, there was no difference in the objective response rate of PVTT [OR=1.13, 95% CI (0.87-1.48), P=0.365], main portal venous pressure and the occurrence adverse event [OR=0.88, CI=0.72-1.08, P=0.212] between two groups. CONCLUSION I125 irradiation stent seems to be more effective in treating hepatocellular carcinoma with portal vein tumor thrombosis. The usage of portal vein stent combined endovascular brachytherapy has the potential to act as an alternative therapy for HCC with PVTT. On account of the limitation of studies included, more studies with high-level evidence, such as RCTs, are requisite to support the above promising results.

Brachytherapy for Oesophageal Carcinoma: A Comprehensive Review of Literature and Techniques. JOURNAL OF RADIOTHERAPY IN PRACTICE 2021.

Abstract
Abstract
Introduction:
Oesophageal carcinoma is one of the fatal cancers mainly because of its rapid spread and poor prognosis. Treatment modalities involves a multimodality approach, including surgery, radiation therapy and chemotherapy. Radiation therapy includes brachytherapy in the form of intraluminal radiation therapy. Brachytherapy permits delivery of high tumouricidal doses to superficial cancerous growth of the oesophagus while delivering much lower doses to the surrounding tissue. It is mostly given in combination with external beam radiation in patients with poor performance scores not likely to tolerate an aggressive chemoradiation regimen or as a boost to concurrent chemoradiotherapy. It is very effective in terms of local tumour control as well as in relieving symptoms in advanced/recurrent disease. Intraoperative brachytherapy and seed brachytherapy have also been tried to address the nodal disease.
Methods:
We undertook a review of the available literature and techniques developed in the past three decades to emphasise the role of brachytherapy in curative or palliative settings in the treatment of oesophageal carcinoma.
Conclusion:
Oesophageal brachytherapy will remain a tangible treatment of oesophageal cancer, although it is less commonly used due to high expertise requirement, lack of established evidence, risk of life-threatening complications and lack of interest in brachytherapy. It offers quick and useful palliation for a prolonged period, along with good quality of life and superior dosimetry. Use of novel applicators may allow dose escalation and lower toxicity. Seed brachytherapy is also emerging as a promising option in nodal recurrences.

[PMID: 33531978 PMCID: PMC7847662 DOI: 10.7150/jca.49663] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 12/03/2020] [Indexed: 11/30/2022] Open
Abstract
Background and Aims: Malignant biliary obstruction is always caused by tumors which are unresectable so that palliative stent placement is conducted for drainage of bile duct tree. Recently, irradiation stent with 125I seeds has been used to improve the stent patency and survival time of patients. We conducted this meta-analysis to evaluate the therapeutic efficacy and safety of biliary stent placement with 125I seeds compared with stent placement alone in patients with malignant biliary obstruction. Methods: We searched Pubmed, Web of Science, ClinicalTrials.gov, Cochrane Library, Embase and CNKI databases for all relevant studies up to 1 May 2020. Patient survival, stent patency, and adverse events were the primary outcome measured. Also, Review Manager 5.3 and Stata/SE15.0 were used to perform the analysis. Results: Eleven randomized controlled trials with a total of 767 patients were included for meta-analysis. Stent combined with 125I seeds showed lower risk of stent occlusion at 3 month (Odds Ratios(OR) = 0.15; 95%CI: 0.05-0.49, P =0.002), 6 month (OR = 0.18; 95%CI: 0.08-0.44, P = 0.0001), 9 month (OR = 0.10; 95%CI: 0.05-0.20, P < 0.00001) and 1 year (OR = 0.15; 95%CI: 0.07-0.31, P < 0.00001) and better mean survival (MD = 125days; 95% CI 91-159 days; P < 0.00001) compared with stent placement alone. Also, reconstructed Kaplan-Meier data demonstrated improved survival in patients treated with stent plus 125I seeds (hazard ratio(HR)= 1.886; 95% CI: 1.609 to 2.210; P < 0.0001) Moreover, our analysis did not show significant difference between the two groups about the risk of adverse events including abdominal pain, hemobilia, pancreatitis, cholangitis and cholecystitis. Conclusion: 125I seeds combined with stent demonstrated superior stent patency and improved survival time compared to stent alone with acceptable complications.

Abstract
OBJECTIVE this study aimed to investigate the clinical efficacy and feasibility of the treatment of advanced esophageal cancer with a combination of a 125I particle-integrated esophageal covered stent and hyperbaric oxygen. METHODS forty-five patients with advanced esophageal cancer were enrolled and were randomly divided into two groups: a treatment group and a control group. Patients in the treatment group were treated with a 125I particle-integrated esophageal covered stent and hyperbaric oxygen, while patients in the control group were treated with a 125I particle-integrated esophageal covered stent. The clinical effects and long-term survival time of the two groups were observed. RESULTS in the treatment group, the complete remission (CR) rate and partial remission (PR) rate of local lesions were 19.2 % and 61.5 %, respectively, and the total effective rate was 80.7 %. In the control group, the CR rate and PR rate of local lesions were 10.5 % and 52.6 %, respectively, and the total effective rate was 63.1 %. The total effective rate was higher in the treatment group than in the control group, which was statistically significant (p < 0.05). CONCLUSION the combination of a 125I particle-integrated esophageal covered stent and hyperbaric oxygen shows a good short- and long-term efficacy in the treatment of advanced esophageal cancer.

Abstract
PURPOSE The purpose of this study was to compare the relative clinical efficacy of radioactive and normal stent insertion for the treatment of inoperable obstructive esophageal squamous cell carcinoma (OESCC). MATERIALS AND METHODS Between January 2014 and December 2018, consecutive OESCC patients were treated via either radioactive or normal stent insertion. RESULTS A total of 42 and 39 OESCC patients were treated via radioactive and normal stent insertion, respectively. These procedures were both technically and clinically successful in all patients. Massive hemorrhage was observed in 7 (16.7%) and 1 (2.6%) patients in radioactive and normal stent groups, respectively (P=0.080). Median stent patency durations were 175 and 136 days in radioactive and normal stent groups, respectively (P=0.004). Median overall survival were 187 and 145 days in the radioactive and normal stent groups, respectively (P=0.011). CONCLUSION Relative to normal stent, radioactive stents showed a higher patency and overall survival in OESCC patients.

Abstract
BACKGROUND Traditional metal stents are not always suitable for patients with circuitous malignant esophageal stricture. PURPOSE We aimed to report the safety and effectiveness of stent insertion using self-expanding segmental radioactive metal stent in the palliation of malignant esophageal stricture. MATERIAL AND METHODS We conducted a retrospective analysis of 22 consecutive patients who underwent insertion of segmental radioactive metal stents from November 2016 to March 2019. Technical success, dysphagia score, and complications were analyzed. Kaplan-Meier analysis was used to analyze the survival time. RESULTS The stenting procedure was successful in all 22 patients with no procedure-related deaths. Twenty-four segmental radioactive metal stents were successfully implanted. A total of 6 (27.3%) complications were found, mainly 5 (22.7%) stent migrations. The median follow-up period was 3.3 months. Stent removal was required in 4 (12.5%) patients due to complete stent migration. The mean dysphagia score decreased significantly after stent insertion (P<0.0001). During follow up, 13 patients survived with no obvious clinical symptom and nine patients died. The mean survival was 9.9 months. CONCLUSION The stenting procedure using self-expanding segmental radioactive metal stents is safe and effective in dysphagia palliation of malignant esophageal stricture.

Abstract
Iodine-125 (125I) seed brachytherapy has been proven to be a safe and effective treatment for advanced esophageal cancer; however, the mechanisms underlying its actions are not completely understood. In the present study, the anti-cancer mechanisms of 125I seed radiation in human esophageal squamous cell carcinoma (ESCC) cells (Eca-109 and KYSE-150) were determined, with a particular focus on the mode of cell death. The results showed that 125I seed radiation significantly inhibited cell proliferation, and induced DNA damage and G2/M cell cycle arrest in both ESCC cell lines. 125I seed radiation induced cell death through both apoptosis and paraptosis. Eca-109 cells were primarily killed by inducing caspase-dependent apoptosis, with 6 Gy radiation resulting in the largest response. KYSE-150 cells were primarily killed by inducing paraptosis, which is characterized by extensive cytoplasmic vacuolation. 125I seed radiation induced autophagic flux in both ESCC cell lines, and autophagy inhibition by 3-methyladenine enhanced radiosensitivity. Furthermore 125I seed radiation induced increased production of reactive oxygen species (ROS) in both ESCC cell lines. Treatment with an ROS scavenger significantly attenuated the effects of 125I seed radiation on endoplasmic reticulum stress, autophagy, apoptosis, paraptotic vacuoles and reduced cell viability. In vivo experiments showed that 125I seed brachytherapy induced ROS generation, initiated cell apoptosis and potential paraptosis, and inhibited cell proliferation and tumor growth. In summary, the results demonstrate that in ESCC cells, 125I seed radiation induces cell death through both apoptosis and paraptosis; and at the same time initiates protective autophagy. Additionally, 125I seed radiation-induced apoptosis, paraptosis and autophagy was considerably mediated by ROS.

Abstract
PURPOSE A radioactive feeding tube was used to achieve both nutrition and brachytherapy for the treatment for malignant esophageal obstruction. We report the safety and effectiveness of this technique. METHODS We conducted a retrospective analysis of 16 consecutive patients who employed this technique from January 2015 to March 2018. The radioactive feeding tube was made by binding the 125I seed chain on the feeding tube. Under fluoroscopic guidance, the tube was inserted into the obstructed esophagus, with the seed chain crossing over the segment of malignant esophageal obstruction. Technical success rate, dysphagia score, procedure time and complications were analyzed. Kaplan-Meier analysis was used to analyze the survival time. RESULTS The radioactive feeding tube was easy to prepare. The technical success rate was 100%, without serious complications such as bleeding or infection. The median procedure time of tube insertion was 44.0 min. The Kamofsky score and Neuhaus dysphagia grading were significantly improved after tube insertion (p < 0.01). On esophageal radiography, the contrast agent passed through the narrow area smoothly. Complete remission (n = 1) and partial remission (n = 13) of local tumor were obtained in 14 patients, and the local tumor control rate was 87.5% (14/16). During follow-up, four patients survived with no obvious clinical symptom and 10 patients died of cancer. The median survival was 12.0 months. CONCLUSION Preparation of the radioactive feeding tube is simple and easy. The insertion of this kind of tube achieves parenteral nutrition and brachytherapy simultaneously and is safe and effective in dysphagia palliation of malignant esophageal stricture. The radiological-radiotherapeutic procedure could be an alternative tool in the case of refusing other treatments by the patients.

Abstract
A systematic review was conducted to provide an overview of the efficacy and safety of 125I irradiation stent placement for patients with hepatocellular carcinoma (HCC) and main portal vein tumor thrombosis (MPVTT). Six studies with 406 patients were included in the final analysis. The median overall survival for patients treated with 125I irradiation stent placement was 10.3 months. The most common radiation-related adverse event was leukopenia. The stent-related adverse events consisted of fever, abdominal pain, hemorrhage, and anorexia. No stent or seed migration was reported. Overall, the use of an 125I irradiation stent has the potential to act as an alternative therapy for patients with HCC with MPVTT.

Factors associated with overall survival and relief of dysphagia in advanced esophageal cancer patients after 125I seed-loaded stent placement: a multicenter retrospective analysis. Dis Esophagus 2019; 32:5393322. [PMID: 30888392 DOI: 10.1093/dote/doz012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2018] [Revised: 11/26/2018] [Accepted: 02/13/2019] [Indexed: 12/11/2022]
Abstract
Iodine-125 (125I) seed-loaded stent placement has served as an effective palliation for malignant esophageal strictures in China. We performed a retrospective study to identify the prognostic factors of this irradiation stent placement in advanced esophageal cancer patients. A total of 201 patients who underwent 125I seed-loaded stent placement were included in this study from June 2012 to March 2016 at five hospitals in China. The Cox regression models adjusted for stratification factors were used, and a stepwise multivariate analysis was performed to predict the overall survival and relief of dysphagia on the basis of pretreatment clinical characteristics, respectively. Three independent prognostic factors were identified for overall survival: histopathological subtype (squamous cell carcinoma vs. adenocarcinoma, hazard ratio [HR] 1.45, 95% confidence interval [CI95%]: 1.01-2.09, P = 0.046), serum total protein (≥66 g/L vs. <66 g/L, HR 0.61, CI95%: 0.48-0.59, P = 0.023), and performance status (<2 vs. ≥2, HR 1.57, CI95%: 1.09-2.08, P = 0.013). Four factors were significantly associated with the relief of dysphagia: T stage (T3 vs. T4, P = 0.003), tumor location (superior vs. inferior, P = 0.049), tumor-node-metastasis classification (IV vs. II, P = 0.025), and age (≥71 years vs. <71 years, P = 0.029). Prognostic factors identified from this analysis can be used to aid clinical decision-making and design future clinical trials.

Comparison of 125 Iodine Seed-Loaded Stents with Different Diameters in Esophageal Cancer: A Multicenter Retrospective Cohort Study. Dysphagia 2019; 35:725-732. [PMID: 31773333 DOI: 10.1007/s00455-019-10080-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 11/16/2019] [Indexed: 01/15/2023]
Abstract
Currently, there are no recommendations or guidelines concerning the preferred diameter of esophageal stents for palliative treatment, owing to the lack of adequate evidence. We therefore conducted a retrospective cohort study to evaluate whether 18 mm stents would achieve a similar function of dysphagia relief with fewer complications and longer survival compared to 20 mm stents. Esophageal cancer patients who underwent 125 iodine seed-loaded stent placement with a diameter of either 18 mm (n = 103) or 20 mm (n = 54) were included at five hospitals in China. The stabilized inverse probability of treatment weighting (IPTW) was used to control potential confounding factors and bias that are inherent in a retrospective study. The primary endpoint was dysphagia relief. Stent-related complications and overall survival were assessed as the secondary endpoints. In the IPTW-adjusted analysis, no significant difference was found in the dysphagia score between the two groups either at 1 week after stent placement or at the last week before death. Despite a comparable rate of overall complications, there was a significantly lower incidence of severe retrosternal pain (15.4% vs. 32.7%, p = 0.013) and a trend toward longer survival (median survival, 176 days [95% confidence interval (CI) 144 to 209] vs. 109 days [92 to 126], p = 0.057) in the 18 mm group. An irradiated stent with a diameter of 18 mm showed a similar outcome of dysphagia relief to that achieved with a 20 mm diameter stent, but halved the incidence of retrosternal pain after stent placement.

Abstract
Purpose: To develop a model to select appropriate candidates for irradiation stent placement among patients with unresectable pancreatic cancer with malignant biliary obstruction (UPC-MBO). Methods: This retrospective study included 106 patients treated with an irradiation stent for UPC-MBO. These patients were randomly divided into a training group (74 patients) and a validation group (32 patients). A clinical model for predicting restenosis-free survival (RFS) was developed with clinical predictors selected by univariate and multivariate analyses. After integrating the radiomics signature, a combined model was constructed to predict RFS. The predictive performance was evaluated with the concordance index (C-index) in both the training and validation groups. The median risk score of progression in the training group was used to divide patients into high- and low-risk subgroups. Results: Radiomics features were integrated with clinical predictors to develop a combined model. The predictive performance was better in the combined model (C-index, 0.791 and 0.779 in the training and validation groups, respectively) than in the clinical model (C-index, 0.673 and 0.667 in the training and validation groups, respectively). According to the median risk score of 1.264, the RFS was significantly different between the high- and low-risk groups (p < 0.001 for the training group, and p = 0.016 for the validation group). Conclusions: The radiomics-based model had good performance for RFS prediction in patients with UPC-MBO who received an irradiation stent. Patients with slow progression should consider undergoing irradiation stent placement for a longer RFS.

Abstract
PURPOSE To investigate the dosimetry of 125I seed-loaded stent system currently used for an adjuvant treatment of portal vein tumor thrombosis (PVTT). METHODS The stent system consisted of an inner metallic stent and outer seed-loaded capsules. Four arrays of 125I seeds were attached longitudinally to the outer surface of the stent at 90° separation. 145 Gy was prescribed at 5 mm from the axes of seed-arrays. For the geometries of the 4-array, and potential 6- and 8-array configurations, treatment planning system (TPS) and Monte Carlo (MC) calculations were performed to evaluate 3D dose distributions and dosimetric impact of the metallic stent. RESULTS The MC simulations indicated the metallic stent reduced a dose to the prescription points by over 10%, compared to the water-based TPS results. The total activity calculated by the water-based TPS to deliver the prescription dose should compensate for this amount of reduction. The MC- and TPS-calculated doses normalized to the prescription points for the current configuration were in agreements within 4.3% on a cylindrical surface along 5 mm from the axes of seed-arrays. The longitudinal underdosage worsened as approaching the edge of arrays, and ranged from 2.8% to 25.5%. The angular underdosage between neighboring arrays was 2.1%-8.9%. CONCLUSIONS With this compensation and a special care of near-edge underdosage, the current 4-array system can provide adequate dose coverage for treatment of PVTT. Further dosimetric homogeneity can be achieved using 6-or 8-array configurations.

Abstract
PURPOSE To assess the efficacy and safety of a newly developed fully covered irradiation stent (FCIS) compared with a partially covered irradiation stent (PCIS) in patients with unresectable malignant dysphagia. MATERIALS AND METHODS Data of 195 patients [158 (81.0%) males, median age of 75 years (range 49-89 years)] who underwent FCIS or PCIS placement for unresectable malignant dysphagia from January 2012 to November 2017 were retrospectively analyzed. The median follow-up time was 181 days (range 4-547 days). Outcomes were measured in terms of recurrent dysphagia (primary), technical success, clinical success, overall survival, and adverse events. Recurrent dysphagia was analyzed by Fine-Gray regression model. RESULTS The technical success rate was 97.8% (87/89) in the FCIS group and 99.1% (105/106) in the PCIS group (P = 0.59). The clinical success rate was 100.0% in both groups. There was no statistically significant difference in the recurrent dysphagia rate between the FCIS and PCIS groups (21.8% vs. 28.6%; P = 0.12). Compared with PCISs, FCISs were associated with a decrease in tissue/tumor growth rate (11.5% vs. 21.9%; P = 0.01), while stent migration rates were statistically comparable (11.5% vs. 5.7%; P = 0.23). The median overall survivals were comparable between the FCIS and PCIS groups (164 days vs. 162 days; P = 0.70). A dysphagia score of 4 and metastasis were risk factors for survival. No significant differences were observed in the rates of adverse events, including chest pain, fistula formation, hemorrhage, and aspiration pneumonia (P > 0.05). CONCLUSION For patients with unresectable malignant dysphagia, this newly developed FCIS can provide efficacy and safety comparable to those of a PCIS. Compared with PCIS, this FCIS is more successful in preventing tissue/tumor growth, with a comparable stent migration rate.

Abstract
Palliation of dysphagia is the cornerstone of palliative treatment in patients with incurable oesophageal cancer. Available palliative options for dysphagia are oesophageal stent placement and radiotherapy. In general, oesophageal stent placement is the preferred therapeutic option in patients with a relatively poor prognosis because of its rapid relief of dysphagia. Regardless of ongoing technical developments, recurrence of dysphagia and stent-related complications are still occurring. For patients with a relatively good prognosis, intra-luminal brachytherapy is advised because of its sustained palliation of dysphagia. Due to limited availability of intra-luminal brachytherapy in clinical practice, fractionated external beam radiation therapy is commonly applied as an alternative. Selection of the optimal palliative approach for patients remains however challenging as conclusive high-quality evidence is limited. Moreover, with the introduction of new palliative treatment options (e.g. palliative chemotherapeutic and radiotherapeutic options) and the concurrent change of patient characteristics, supporting evidence from large randomised studies is warranted.

Abstract
Background To evaluate the safety and efficacy of a novel radioactive bare metal stent (RBMS) compared with a conventional bare metal stent (CBMS) in patients with inoperable malignant airway obstruction. Methods This prospective study was approved by the Institutional Ethics Committee, and informed consent was obtained from each participant. Patients with malignant airway obstruction who had dyspnea were randomly assigned to receive RBMS or CBMS placement. The primary endpoint was stenosis grade, while the secondary endpoints were technical success, overall survival, and complications. A p value of <0·05 was considered statistically significant. Results Between September 2013 and July 2015, 66 patients with inoperable malignant airway obstruction received stent placement fluoroscopically (33 in either group). The median follow-up time was 154 days (range, 15–335 days). The baseline stenosis was immediately relieved in both groups after stent placement, and the stenosis grades in the RBMS group were significantly lower than that in the CBMS group since the second month (p < 0·05). The technical success rates of stent placement were 100% in both groups. The median survival in the RBMS group was significantly longer than that in the CBMS group (170 days vs. 123 days, p < 0·05). There was no significant difference in the incidence of complications between the two groups (p < 0·05). Conclusions The placement of RBMS in patients with inoperable malignant airway obstruction is feasible and safe, and it significantly reduces restenosis and improves overall survival compared with the placement of CBMS. The baseline stenosis was immediately relieved in both groups after stent placement. The stenosis grades in the RBMS group were significantly lower than that in the CBMS group since the second month. The technical success rates of stent placement were 100% in both groups. The median survival in the RBMS group was significantly longer than that in the CBMS group. There was no significant difference of the incidence of complications between the two groups.
Malignant airway obstruction (MAO) is a serious situation of 20-30% cases of lung cancer, resulting in dyspnea, decreased functional status, and asphyxiation risk. Conventional stent placement provides immediate palliation of dyspnea. However, stent restenosis occurs during the follow up. A novel radioactive bare metal stent (RBMS) loaded with 125I seed was developed for preventing such restenosis. Our study showed that placement of RBMS in patients with inoperable malignant airway obstruction is feasible and safe, and it significantly reduces the restenosis and improves overall survival compared with placement of conventional stent.

Abstract
Background: Portal-vein stent combined with one iodine-125 (125I) seed strand has become a new treatment for portal vein tumor thrombosis. However, dosimetric aspects of this irradiation stent have not been reported. Therefore, we aimed to undertake dosimetric analyses comparing portal-vein stents combined with different numbers of 125I seed strands. Methods: A water cylinder was created by a treatment-planning system to simulate a portal-vein stent. The stent was combined with one, two, or three 125I seed strands (Groups I, II, and III, respectively). At different prescribed doses (PDs), 125I seeds of identical activities were loaded on Groups I–III. Conformation number (CN), external volume index, and homogeneity index were calculated. Linear regression analyses were used to evaluate the obtained data. Results: For identical 125I seed activity, when the 125I seed strand increased from one chain to two, D90 (dose delivered to 90% of the target volume) increased by ≥184%; when it increased from two chains to three, D90 increased by ≥63%. When the PD was 105 Gy and 125I seed strands increased from one chain to two, V100 (percentage of the target volume receiving ≥90% of the PD) increased by 158–249%; when it increased from two chains to three, V100 increased by 7–175%. CN was correlated positively with 125I seed activity (B = 0.479, P < 0.001) and number of 125I seed strands (B = 0.201, P < 0.001) and was independent of PD (B = −0.002, P = 0.078). Conclusions: A portal-vein stent combined with a single 125I seed strand could not meet dosimetry requirements. For a stent combined with two 125I seed strands, when the PD was 105 Gy and seed activity was 0.7 mCi, the dose distribution could satisfy dosimetry requirements. For a stent combined with three 125I seed strands, if the PD was 105, 125, or 145 Gy, the recommended seed activities were 0.5, 0.5, and 0.6 mCi, respectively.

Irradiation stents vs. conventional metal stents for unresectable malignant biliary obstruction: A multicenter trial. J Hepatol 2018; 68:970-977. [PMID: 29331343 DOI: 10.1016/j.jhep.2017.12.028] [Citation(s) in RCA: 72] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 12/22/2017] [Accepted: 12/22/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Placement of an irradiation stent has been demonstrated to offer longer patency and survival than an uncovered self-expandable metallic stent (SEMS) in patients with unresectable malignant biliary obstruction (MBO). We aim to further assess the efficacy of an irradiation stent compared to an uncovered SEMS in those patients. METHODS We performed a randomized, open-label trial of participants with unresectable MBO at 20 centers in China. A total of 328 participants were allocated in parallel to the irradiation stent group (ISG) or the uncovered SEMS group (USG). Endpoints included stent patency (primary), technical success, relief of jaundice, overall survival, and complications. RESULTS The first quartile stent patency time (when 25% of the patients experienced stent restenosis) was 212 days for the ISG and 104 days for the USG. Irradiation stents were significantly associated with a decrease in the rate of stent restenosis (9% vs. 15% at 90 days; 16% vs. 27% at 180 days; 21% vs. 33% at 360 days; p = 0.010). Patients in the ISG obtained longer survival time (median 202 days vs. 140 days; p = 0.020). No significant results were observed in technical success rate (93% vs. 95%; p = 0.499), relief of jaundice (85% vs. 80%; p = 0.308), and the incidence of grade 3 and 4 complications (8.5% vs. 7.9%; p = 0.841). CONCLUSIONS Insertion of irradiation stents instead of uncovered SEMS could improve patency and overall survival in patients with unresectable MBO. LAY SUMMARY For patients with unresectable malignant biliary obstruction (MBO), placement of a self-expandable metallic stent (SEMS) is a recommended palliative modality to relieve pruritus, cholangitis, pain, and jaundice. However, restenosis is a main pitfall after stent placement. Data from this first multicenter randomized controlled trial showed that insertion of an irradiation stent provided longer patency and better survival than a conventional metal stent.

Abstract
Approximately half of the patients diagnosed with oesophageal cancer present with unresectable or metastatic disease. Treatment for these patients aims to control dysphagia and other cancer-related symptoms, improve quality of life and prolong survival. In the past 25 years, modestly improved outcomes have been achieved in the treatment of patients with inoperable non-metastatic cancer who are medically not fit for surgery or have unresectable, locally advanced disease. Concurrent chemoradiotherapy offers the best outcomes in these patients. In distant metastatic oesophageal cancer, several double-agent or triple-agent chemotherapy regimens have been established as first-line treatment options. In addition, long-term results of multiple large randomized phase III trials using additional targeted therapies have been published in the past few years, affecting contemporary clinical practice and future research directions. For the local treatment of malignant dysphagia, various treatment options have emerged, and self-expandable metal stent (SEMS) placement is currently the most widely applied method. Besides the continuous search for improved SEMS designs to minimize the risk of associated complications, efforts have been made to develop and evaluate the efficacy of antireflux stents and irradiation stents. This Review outlines the current evidence and ongoing trends in the different modern-day, multidisciplinary interventions for patients with unresectable or metastatic oesophageal cancer with an emphasis on key randomized trials.

Role of Esophageal Metal Stents Placement and Combination Therapy in Inoperable Esophageal Carcinoma: A Systematic Review and Meta-analysis. Dig Dis Sci 2018; 63:1025-1034.

Abstract
INTRODUCTION More than 50% of patients with esophageal cancer already have inoperable disease at the time of diagnosis. Controversy surrounds the outcomes of patients with advanced esophageal cancer who receive palliative care by either stent alone or stent plus an additional modality. We set out to perform a systematic review and meta-analysis of studies assessing the use of metal stents as treatment options for symptomatic improvement, survival, and adverse events. METHODS We searched Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception until January 14, 2016, as well as other databases for randomized controlled trials (RCTs) comparing esophageal stent versus either esophageal stent plus brachytherapy, radiotherapy, or chemotherapy. For quality assurance purposes throughout the systematic review, multiple independent extractions were performed, and the process was executed as per the standards of the Cochrane collaboration. Primary outcomes were mean change in dysphagia score, overall survival, and quality of life. Secondary outcomes were adverse events including fever, severe pain, aspiration, fistula, stent migration, perforation, and restenosis. RESULTS Eight RCTs enrolling 732 patients were included with three distinct comparisons: stents combination therapy vs stents alone (5 studies, n = 417), stents alone versus brachytherapy alone (2 studies, n = 274), and stents + brachytherapy vs brachytherapy alone (1 study, n = 41). Stents combination therapy was defined as stents plus radiotherapy, chemotherapy, or both. Mean change in dysphagia scores favored stents combination therapy versus stents alone, and the effect was seen in patients surviving longer than 3 months. Stents combination therapy was also associated with a more favorable overall survival. The risks of stent migration, aspiration pneumonia, and restenosis were lower in the stents combination group compared to stents alone, while the risks of severe pain, hemorrhage, and fistula formation were higher. Changes in dysphagia scores and overall survival did not differ significantly in the brachytherapy-alone vs stents-alone comparison. The risk of fistula formation and hemorrhage were higher in the stents-alone group, while the risk of perforation was lower, compared to brachytherapy alone. Quality of life improvements were seen in all treatment groups, but were not pooled in analysis due to differing methods of measurement. DISCUSSION While there appears to be no immediate short-term differences, those who live longer than 3 months experience a significant improvement in dysphagia score using a stents combination therapy approach vs stents alone. The combination therapy significantly improves the overall survival as well as showed improvements in quality of life scores. Larger randomized controlled trials are needed to assess improvements in dysphagia score, overall survival, quality of life, and adverse events.

Abstract
Background: A novel radioactive 125I seed-loaded biliary stent has been used for patients with malignant biliary obstruction. However, the dosimetric characteristics of the stents remain unclear. Therefore, we aimed to describe the dosimetry of the stents of different lengths — with different number as well as activities of 125I seeds. Methods: The radiation dosimetry of three representative radioactive stent models was evaluated using a treatment planning system (TPS), thermoluminescent dosimeter (TLD) measurements, and Monte Carlo (MC) simulations. In the process of TPS calculation and TLD measurement, two different water-equivalent phantoms were designed to obtain cumulative radial dose distribution. Calibration procedures using TLD in the designed phantom were also conducted. MC simulations were performed using the Monte Carlo N-Particle eXtended version 2.5 general purpose code to calculate the radioactive stent's three-dimensional dose rate distribution in liquid water. Analysis of covariance was used to examine the factors influencing radial dose distribution of the radioactive stent. Results: The maximum reduction in cumulative radial dose was 26% when the seed activity changed from 0.5 mCi to 0.4 mCi for the same length of radioactive stents. The TLD's dose response in the range of 0–10 mGy irradiation by 137Cs γ-ray was linear: y = 182225x − 6651.9 (R2= 0.99152; y is the irradiation dose in mGy, x is the TLDs’ reading in nC). When TLDs were irradiated by different energy radiation sources to a dose of 1 mGy, reading of TLDs was different. Doses at a distance of 0.1 cm from the three stents’ surface simulated by MC were 79, 93, and 97 Gy. Conclusions: TPS calculation, TLD measurement, and MC simulation were performed and were found to be in good agreement. Although the whole experiment was conducted in water-equivalent phantom, data in our evaluation may provide a theoretical basis for dosimetry for the clinical application.

Abstract
OBJECTIVES To evaluate therapeutic outcomes of intraluminal brachytherapy (ILBT) for malignant obstructive jaundice (MOJ) against stent alone. METHODS The PubMed, EMBASE, Cochrane Library, CNKI, Wan Fang, VIP and ClinicalTrials.gov databases were searched for all relevant comparative studies from the earliest available date up to 1 May 2017. Subgroup analyses were performed according to the type of study design and type of stent. RESULTS Twelve studies that compared ILBT versus stent alone were eligible. A total of 641 participants with MOJ were included in our meta-analysis. A total of 340 participants were treated with intraluminal brachytherapy (ILBT); the other 301 participants were treated with biliary stent alone (stent group). ILBT was associated with lower risk of stent occlusion (OR 0.19; 95% CI 0.13-0.28; P < 0.00001) and better mean survival (MD = 3.15; 95% CI 2.64-3.66; P < 0.00001) compared with stent alone. However, the two groups were similar in number of complications (OR 0.84; 95% CI 0.45-1.56; P = 0.578), post-treatment reduced level of total bilirubin (TBIL) (MD = 22.71; 95% CI - 7.24-52.65; P = 0.14), post-treatment reduced level of direct bilirubin (DBIL) (MD = - 3.67; 95% CI - 14.09-6.75; P = 0.49), post-treatment reduced level of alanine aminotransferase (ALT) (MD = 21.09; 95% CI - 5.09-47.28; P = 0.11) and post-treatment reduced level of aspartate aminotransferase (AST) (MD = 20.86; 95% CI - 45.86-87.58; P = 0.54). CONCLUSIONS ILBT was significantly superior to stent alone in terms of stent occlusion and mean survival. Meanwhile, ILBT had comparable outcomes to stent alone in terms of complications and post-treatment reduced levels of TBIL, DBIL, ALT and AST. Therefore, ILBT may be considered a preferable technique for MOJ.

Abstract
Background Palliative treatments and stents are necessary for relieving dysphagia in patients with esophageal cancer. The aim of this study was to simultaneously compare available treatments in terms of complications. Methods Web of Science, Medline, Scopus, Cochrane Library and Embase were searched. Statistical heterogeneity was assessed using the Chi2 test and was quantified by I2. The results of this study were summarized in terms of Risk Ratio (RR). The random effects model was used to report the results. The rank probability for each treatment was calculated using the p-score. Results Out of 17855 references, 24 RCTs reported complications including treatment related death (TRD), bleeding, stent migration, aspiration, severe pain and fistula formation. In the ranking of treatments, thermal ablative therapy (p-score = 0.82), covered Evolution® stent (p-score = 0.70), brachytherapy (p-score = 0.72) and antireflux stent (p-score = 0.74) were better treatments in the network of TRD. Thermal ablative therapy (p-score = 0.86), the conventional stent (p-score = 0.62), covered Evolution® stent (p-score = 0.96) and brachytherapy (p-score = 0.82) were better treatments in the network of bleeding complications. Covered Evolution® (p-score = 0.78), uncovered (p-score = 0.88) and irradiation stents (p-score = 0.65) were better treatments in network of stent migration complications. In the network of severe pain, Conventional self-expandable nitinol alloy covered stent (p-score = 0.73), polyflex (p-score = 0.79), latex prosthesis (p-score = 0.96) and brachytherapy (p-score = 0.65) were better treatments. Conclusion According to our results, thermal ablative therapy, covered Evolution® stents, brachytherapy, and antireflux stents are associated with a lower risk of TRD. Moreover, thermal ablative therapy, conventional, covered Evolution® and brachytherapy had lower risks of bleeding. Overall, fewer complications were associated with covered Evolution® stent and brachytherapy.

Abstract
BACKGROUND AND AIMS Self-expandable metallic stents are considered the best palliative treatment of dysphagia for patients with advanced esophageal cancer. Adverse events (AEs) are a major concern, especially in patients with better prognosis and longer survival. The present study aimed to evaluate the AEs of patients who survived longer than 6 months with esophageal stents in place. METHODS This is a retrospective analysis of a prospectively collected database including all patients submitted to esophageal stent placement for the palliation of malignant diseases during the period from February 2009 to February 2014 at a tertiary care academic center who had stents longer than 6 months. RESULTS Sixty-three patients were included. Mean follow-up was 10.7 months. Clinical success was achieved in all patients, and the median stent patency was 7.1 months. AEs occurred in 40 patients (63.5%), totaling 62 AEs (mean, 1.5 AEs per patient). Endoscopic management of AEs was successful in 84.5% of cases, with a mean of 1.6 reinterventions per patient. The univariate analysis revealed that performance status, age, and post-stent radiotherapy presented a trend to higher risk of AEs. The multivariate analysis revealed that only performance status was associated with AEs (P = .025; hazard ratio, 4.1). CONCLUSIONS AEs are common in patients with long-term esophageal stenting for malignancy. However, AEs were not related to higher mortality rate, and most AEs could be successfully managed by endoscopy. Only performance status was a risk factor for AEs. Our data suggest that metallic stenting is a valid option for the treatment of malignant esophageal conditions, even when survival longer than 6 months is expected.

Abstract
Surgical resection is the primary treatment option for retroperitoneal liposarcomas, but complete resection is difficult and postoperative recurrence and metastasis are common. This prospective study analyzed the feasibility and efficacy of microwave ablation combined with iodine‐125 seed implantation in the local control of recurrent retroperitoneal liposarcomas. Introduction. The objective of the present study was to evaluate the feasibility, safety, and short‐term efficacy of microwave ablation (MWA) combined with iodine‐125 (125I) seed implantation in recurrent retroperitoneal liposarcomas (rRPLs). Materials and Methods. From September 2012 to March 2015, 11 patients were enrolled in this prospective study. Eleven tumors (median, 9 cm; range, 5.5–12.5 cm) were treated with computerized tomography‐guided MWA for 11 sessions and 125I seed implantation for 18 sessions. 125I seed implantation was performed 4 weeks after MWA. Results. There were no procedure‐related deaths. Post‐MWA pain (grade ≥2) was the most common complication (6 of 11 patients, 54.5%), and fever (grade ≥2) was observed in two patients. Reversible nerve injury, defined as transient limb paresthesia or leg weakness, was observed in one patient. There were fewer complications associated with the 125I seed implantation procedure compared with the MWA procedure. All 11 patients who underwent the MWA procedure achieved a partial response (PR), according to the modified Response Evaluation Criteria in Solid Tumors, 1 month post‐ablation; after 125I seed implantation was performed, a complete response was observed in three, five, and six target tumors in 3, 6, and 12 months, respectively. Conclusion. In selected patients with rRPLs, MWA combined with 125I seed implantation is feasible and safe with favorable local control efficacy. Implications for Practice. This study evaluated the feasibility, safety, and short‐term efficacy of microwave ablation (MWA) combined with iodine‐125 (125I) seed implantation in recurrent retroperitoneal liposarcomas (rRPLs). Results suggest that a single session of MWA may be not sufficient in large‐volume rRPLs and that as a supplement treatment, 125I seed implantation is safe and easy accessible. MWA combined with 125I seed has excellent local control effectiveness, and long‐term efficacy and survival benefit still need to be more comprehensively evaluated.

Abstract
Esophageal stents have been used to palliate patients with dysphagia caused by esophageal cancer. Early rigid plastic prostheses have been associated with a high risk of complications. However, with the development of self-expanding stents, it has developed into a widely accepted method for treating malignant esophageal strictures and esophagorespiratory fistulas (ERFs). The present review covers various aspects of self-expanding metallic stent placement for palliating esophageal cancer, including its types, placement procedures, indications, contraindications, complications, and some of innovations that will become available in the future.

Abstract
Stent insertion is a feasible and safe palliative management for advanced unresectable esophageal cancer. The aim of this study is to assess the efficacy of radioactive stent for unresectable esophageal cancer compared with conventional stent. Systematic searches of the PubMed and Web of science are dated from their beginning to January 25, 2016. Studies that compared radioactive stent with conventional stent for unresectable esophageal cancer were included. The outcomes were postimplantation survival, relief of dysphagia, and complications related to stent implant. Six studies with 539 patients were included. All of them used stent equipped with radioactive iodine beads as a radioactive stent. The pooled weighted mean difference for median survival was 2.734 months (95% CI 1.710-3.775; Z = 5.21, P = 0.000) between two groups. The 1,3,6 month survival rates were higher in radioactive stents than conventional stent, with the pooled ORs 3.216 (95% CI 1.293-7.999; Z = 2.51, P = 0.012), 3.095 (95% CI 1.908-5.020; Z = 4.58, P = 0.000), and 7.503 (95% CI 2.206- 25.516; Z = 3.23, P = 0.001, respectively). The pooled hazard ratio was 0.464 (95% CI 0.328-0.655; Z = 4.35, P = 0.000) between two groups. For relief of dysphagia, two stents all have good relief of the dysphagia effect, but radioactive stent showed a better effect at 3, 6 months follow-up after implantation. For complications related to stent implant, no significant differences were found between two stents in terms of severe chest pain (30.0% vs. 35.7%, OR 0.765, 95% CI 0.490-1.196), gastroesophageal reflux (18.6% vs. 16.1%, OR 1.188, 95% CI 0.453-3.115), fever (12.1% vs. 12.1%, OR 1.014, 95% CI 0.332-3.097), bleeding (16.7% vs. 14.2%, OR 1.201, 95% CI 0.645-2.236), perforation or fistula (6.1% vs. 9.0%, OR 0.658, 95% CI 0.291-1.486), pneumonia (10.7% vs. 14.1%, OR 0.724, 95% CI 0.343-1.526), stent migration (7.0% vs. 10.2%, OR 0.651, 95% CI 0.220-1.924), and restenosis (24.2% vs. 20.6%, OR 1.228, 95% CI 0.674-2.239). Radioactive stent insertion had potential benefits for palliative management for patients with unresectable esophageal cancer. This method prolonged survival and dysphagia relief period without more complications. However, this conclusion should be confirmed by more trials.
