[PMID: 38403626 PMCID: PMC10895717 DOI: 10.1186/s12885-024-12013-2] [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: 08/30/2023] [Accepted: 02/16/2024] [Indexed: 02/27/2024] Open
Abstract
OBJECTIVES To evaluate the safety and effectiveness of computed tomography (CT)-guided radioactive 125I seeds brachytherapy (RISB) for lung oligometastases (LO) from colorectal cancer (CRC). METHODS Data for 144 LOs from 70 CRC patients who underwent CT-guided RISB were retrospectively analyzed. The primary endpoints were progression-free survival (PFS) and overall survival (OS), and the secondary endpoints were technical success, local control rate (LCR), and complications. Kaplan-Meier method was used for survival analysis. Cox model was used to identify the independent predictors of poor prognosis. RESULTS The RISB procedures were successfully performed in all patients, and the success rate was 100%. The median follow-up was 27.8 months. The median PFS was 10.0 months (95% CI: 8.9-11.1) and the 1- and 2-year PFS rates were 32.9% and 5.9%, respectively. On multivariate analysis, serum carcinoembryonic antigen (CEA) ≤ 15 ng/ml (P = 0.048), middle-high differentiated pathological classification (P = 0.015), primary TNM stages I-III (P = 0.001), LO number ≤ 2 (P < 0.001) and cumulative gross tumor volume (GTV) ≤ 40 cm3 (P < 0.001) showed superior PFS. The median OS was 30.8 months (95% CI: 27.1-34.4) and the 1-, 2-, and 3-year OS rates were 95.7%, 67.4%, and 42.5%, respectively. On multivariate analysis, serum CEA ≤ 15 ng/ml (P = 0.004), middle-high differentiated pathological classification (P < 0.001), primary TNM stages I-III (P < 0.001), LO number ≤ 2 (P < 0.001), cumulative GTV ≤ 40 cm3 (P < 0.001) and system treatments combined with chemotherapy and target therapy (P < 0.001) showed superior OS. The LCR for 3, 6, and 12 months was 97.9%, 91.0%, and 83.6%, respectively. There were 4 cases of pneumothorax at 5.7% that required drainage. CONCLUSIONS RISB for LO from CRC is safe and effective, and serum CEA, TNM stage, LO number, cumulative GTV, and system treatments should be emphasized for long OS.

Brachytherapy 2023; 22:882-888. [PMID: 37758577 DOI: 10.1016/j.brachy.2023.08.005] [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: 04/14/2023] [Revised: 08/02/2023] [Accepted: 08/18/2023] [Indexed: 09/29/2023]
Abstract
PURPOSE To analyze the short-term clinical response of radioactive iodine-125 seed implantation (I125-SI) in patients of non-small-cell lung cancer (NSCLC) and explore possible correlations of various metabolic parameters of pretreatment FDG PET-CT with the short-term efficacy of this treatment modality. METHODS AND MATERIALS The present study is a retrospective analysis of treatment records of 46 NSCLC patients who were treated with I125-SI for lung tumors in Tianjin First Central Hospital from January 2016 to December 2018. The correlation among parameters D90, gender, pathological pattern, age, maximum tumor diameter, Metabolic Tumor Volume (MTV), SUVmax, SUVpeak, SUVmean, Total Lesion Glycolysis (TLG), High metabolic tumor cell ratio (HMR) and Carcinoembryonic antigen(CEA)with short-term efficacy of I125-SI was analyzed by two independent-sample t-test, Mann-Whitney U test or Chi-squared test and binary logistic regression. RESULTS After uneventful completion of treatment, patients were followed up at regular intervals. At the first month followup, none of cases showed complete response (CR), while 4 cases showed partial response (PR). After 3 months, there were 2 cases of CR, and 25 cases of PR; after 6 months, there were 5 cases of CR, and 27 cases of PR. D90 (p= 0.028, OR:1.075, 95% CI:1.008-1.147), MTV (p= 0.026, OR: 0.918, 95% CI: 0.851-0.990), HMR (p= 0.020, OR: 0.003, 95% CI: 0-0.407) were independent predictors for the short-term efficacy. The predictive accuracy of MTV was medium (AUC = 0.781; cutoff value = 44.58). However, the predictive accuracies of D90 and HMR were low, with the values of AUC being 0.650 for both the parameters, and their cutoff values being 127.8 Gy and 0.27 respectively. CONCLUSIONS I125-SI is an effective therapy with few complications in NSCLC patients. Small MTV, high D90 and low HRM were found to be linked with better local control at 6 months postimplantation.

Abstract
Objectives To investigate the potential mechanisms of 125I seed implantation therapeutic treatment on inactivating the VEGFR2/PI3K/AKT pathway in cholangiocarcinoma. Methods The human cholangiocarcinoma cell lines HCCC-9810 and HuCCT1 were purchased for in vitro studies. The BALB/c nude mice were obtained for in vivo studies. The proliferation of cells was detected by CCK-8, colony formation, and BrdU staining. The migration and invasion of cells were determined by wound healing assay and Transwell assay, respectively. Hematoxylin and eosin staining was utilized for histological evaluation. Protein expression was determined by western blotting and immunohistochemistry. Results Compared with the control group, .6 mCi group and .8 mCi group inhibited cholangiocarcinoma cells proliferation, invasion, migration, and promoted apoptosis, the protein expression of p-VEGFR2, VEGFR2, PI3K, p-AKT/AKT, cyclin B1, cyclin A, CDK1, and Bcl-2 was decreased. Similar results were obtained from in vitro experiments. However, when VEGF is overexpressed, the inhibitory effect of .8 mCi was partially significantly reversed on cholangiocarcinoma cells. The in vivo studies further confirmed the inhibitory effects of .6 mCi group and .8 mCi group on cholangiocarcinoma. Conclusion 125I seed irradiation could inhibit cholangiocarcinoma cells proliferation, migration, and invasion and promote apoptosis through inactivation of the VEGFR2/PI3K/AKT signaling pathway.

Abstract
INTRODUCTION To retrospectively evaluate the safety and efficacy of computed tomography (CT)-guided iodine-125 (125I) seed implantation for patients with abdominal incision metastases from colorectal cancer. MATERIALS AND METHODS Data of patients with abdominal incision metastases of colorectal cancer from November 2010 to October 2020 were retrospectively reviewed. Each incisional metastasis was percutaneously treated with 125I seed implantation under CT guidance. Follow-up contrast-enhanced CT was reviewed, and the outcomes were evaluated in terms of objective response rate, complications, and overall survival. RESULTS A total of 17 patients were enrolled in this study. The median follow-up was 18 months (range, 2.7-22.1 months). At 3, 6, 12, and 18 months after the treatment, objective response rate was 52.9%, 63.6%, 33.3%, and 0%, respectively. A small amount of local hematoma occurred in two patients and resolved spontaneously without any treatment. Two patients experienced a minor displacement of radioactive seeds with no related symptoms. Severe complications, such as massive bleeding and radiation injury, were not observed. No ≥ grade 3 adverse events were identified. By the end of follow-up, 14 patients died of multiple hematogenous metastases. The one-year overall survival rate was 41.6%, and the median overall survival was 8.6 months. CONCLUSION CT-guided 125I seed implantation brachytherapy is safe and feasible for patients with abdominal incision metastases from colorectal cancer.

Abstract
Brachytherapy remains an underrecognized and underutilized radiation therapy modality for the treatment of spinal tumors. This article summarizes the existing body of medical literature on the usage, indications, techniques, and outcomes of brachytherapy for the treatment of spine tumors. The disease pathology most commonly treated with brachytherapy is metastatic spine cancer, rather than primary bone tumors of the spine. Brachytherapy can be used alone, as percutaneous needle injections; however, it is more often used in conjunction with open surgery or cement vertebral body augmentation. Although the data are still relatively sparse, studies show consistent benefit from brachytherapy in terms of improvements in pain, function, local recurrence rate, and overall survival. Brachytherapy is also associated with a favorable complication profile.

Abstract
Background A more extensive surgical resection of glioma contributes to improved overall survival (OS) and progression-free survival (PFS). However, some patients miss the chance of surgical resection when the tumor involves critical structures. Purpose The present study aimed to assess the feasibility of neoadjuvant 125I brachytherapy followed by total gross resection for initially inoperable glioma. Methods Six patients diagnosed with inoperable glioma due to invasion of eloquent areas, bihemispheric diffusion, or large tumor volume received 125I brachytherapy. Surgical resection was performed when the tumor shrank, allowing a safe resection, assessed by the neurosurgeons. Patients were followed up after surgery. Results Shrinkage of the tumor after adjuvant 125I brachytherapy enabled a total gross resection of all six patients. Four patients were still alive at the last follow-up, with the longest survival time of more than 50 months, two of which returned to everyday life with a KPS of 100. Another two patients had neurological injuries with KPSs of 80 and 50, respectively. One patient with grade II glioma died 34 months, and another with grade IV glioma died 40 months after the combined therapy. Conclusions In the present study, the results demonstrated that 125I brachytherapy enabled a complete resection of patients with initially unresectable gliomas. 125I brachytherapy may offer a proper neoadjuvant therapy method for glioma.

Abstract
Purpose: To analyze the outcome and prognosis of patients with
refractory cervical lymph node metastasis of thoracic esophageal squamous cell
carcinoma after external irradiation, who underwent interstitial 125I
brachytherapy as a salvage treatment with a CT-guided coplanar template-assisted
technique. We also want to compare the dosimetry of 3D printed coplanar
template-assisted interstitial 125I brachytherapy preoperative and
postoperative, and to explore the accuracy of this technology. Material
and methods: We retrospectively collected and analyzed the results of
32 patients with refractory cervical lymph node metastasis of thoracic
esophageal squamous cell carcinoma after external irradiation, who underwent
interstitial 125I brachytherapy as a salvage treatment with a
CT-guided coplanar template-assisted technique from January 2012 to December
2017. Results: The actual D90 were 114 to 240 Gy, and the median
postoperative dosimetry assessment was 177.5 Gy. The local control rates at 3,
6, 9, and 12 months were 87.5%, 59.38%, 40.63%, and 31.25%, respectively. The
median local control time was 7.5 months. The median overall survival time was
10.5 months (95% CI, 8.9-13.4), and the survival rates of 1- and 2-year,
respectively, were 43.75% and 9.38%. There were 36 lesions in 32 patients. By
performing a paired t-test analysis, there was no significant
difference in D90, D100, V100, V150, V200, GTV volume, CI, EI, and HI between
preoperative and postoperative (P > .05).
Conclusions: Interstitial 125I brachytherapy can be
used as a salvage treatment for patients with refractory cervical lymph node
metastasis of thoracic esophageal squamous cell carcinoma after external
irradiation. With the auxiliary function of 3D printed coplanar template, the
main dosimetry parameters verified after the operation can meet the requirements
of the preoperative plan with good treatment accuracy.

Percutaneous biliary stent combined with brachytherapy using 125I seeds for treatment of unresectable malignant obstructive jaundice: A meta-analysis. World J Clin Cases 2021; 9:10979-10993. [PMID: 35047608 PMCID: PMC8678863 DOI: 10.12998/wjcc.v9.i35.10979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 08/03/2021] [Accepted: 11/04/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Malignant obstructive jaundice (MOJ) is a common pathologic manifestation of malignant biliary obstruction. Recently, several clinical trials have explored the clinical effectiveness of intraluminal 125I seed-based brachytherapy for MOJ patients, and various outcomes have been reported.
AIM To assess the efficacy and safety of percutaneous biliary stents with 125I seeds compared to conventional metal stents in patients with unresectable MOJ.
METHODS A systematic search of English-language databases (PubMed, Embase, Cochrane Library, and Web of Science) was performed to identify studies published prior to June 2020 that compared stents with or without 125I seeds in the treatment of unresectable MOJ. The outcomes analyzed included primary outcomes (stent patency and overall survival) and secondary outcomes (complications and liver function parameters).
RESULTS Six randomized controlled trials and four retrospective studies involving 875 patients were eligible for the analysis. Of the 875 included patients, 404 were treated with 125I seed stents, while 471 were treated with conventional stents. Unadjusted pooled analysis demonstrated that compared to conventional stents, 125I seed stents extended the stent patency time [hazard ratio (HR) = 0.36, 95% confidence interval (CI) = 0.28-0.45, P < 0.0001] and overall survival period (HR = 0.52, 95%CI = 0.42–0.64, P < 0.00001). Subgroup analyses based on the type of 125I seed stent and type of study design showed consistent results. However, there were no significant differences in the occurrence of total complications [odds ratio (OR) = 1.12, 95%CI = 0.75-1.67, P = 0.57], hemobilia (OR = 1.02, 95%CI = 0.45-2.3, P = 0.96), pancreatitis (OR = 1.79, 95%CI = 0.42-7.53, P = 0.43), cholangitis (OR = 1.13, 95%CI = 0.60-2.13, P = 0.71), or pain (OR = 0.67, 95%CI = 0.22-2, P = 0.47). In addition, there were no reductions in the levels of serum indices, including total bilirubin [mean difference (MD) = 10.96, 95%CI = -3.56-25.49, P = 0.14], direct bilirubin (MD = 7.37, 95%CI = -9.76-24.5, P = 0.4), alanine aminotransferase (MD = 7.52, 95%CI = -0.71-15.74, P = 0.07), and aspartate aminotransferase (MD = -4.77, 95%CI = -19.98-10.44, P = 0.54), after treatment. Publication bias was detected regarding the outcome overall survival; however, the conclusions were not changed after the adjustment.
CONCLUSION Placement of stents combined with brachytherapy using 125I seeds contributes to a longer stent patency and higher overall survival than placement of conventional stents without extra complications or severe liver damage. Thus, it can be considered an effective and safe treatment for unresectable MOJ.

The control group received chemotherapy. Observation group (80 cases) was treated with lentinan combined with (125)I brachytherapy on the basis of control group, and the efficacy, adverse reactions, and Karnofsky Performance Scale (KPS) and quality of life scale (QOL) scores of the two groups were analyzed and compared. Results After treatment, the levels of CA125, CA199, and CA724 in the 2 groups were markedly lower than those before treatment, and the observation group was lower than the control group (P < 0.05). After treatment, the proportion of CD4+/CD8+ cells and helper T cells and NK cells in the control group remarkably depleted, while the proportion of CD4+/CD8+ cells, NK cells, and B cells in the observation group increased significantly compared to that before treatment, and the level of IgA, IgG, and IgM in the control group decreased, while that in the observation group showed no conspicuous difference compared with that before chemotherapy (P > 0.05). The effective rate of observation group (85%) was higher than that of control group (75%) (P < 0.05). The overall survival of patients in the control group was (16.2 ± 2.04) months and that of the observation group was (24.8 ± 1.8) months. KPS and QOL scores in both groups were enormously higher than those before treatment, and the observation group was higher than the control group (P < 0.05). The incidence of hemoglobin reduction, leukopenia, aglobulia, granulocytopenia, nausea and vomiting, hepatorenal toxicity, and neurovirulence in the observation group was significantly lower than that in the control group. Conclusion Lentinan combined with (125)I brachytherapy is effective in treating recurrent ovarian cancer, with mild adverse reactions and good tolerance.

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.

Cancers (Basel) 2021; 13:cancers13143493. [PMID: 34298703 PMCID: PMC8304109 DOI: 10.3390/cancers13143493] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 02/07/2023] Open
Abstract
Brachytherapy (BT), a type of focal anti-cancer radiotherapy, delivers a highly focused radiation dose to localized tumors, sparing surrounding normal tissues. Recent technological advances have helped to increase the accuracy of BT and, thus, improve BT-based cancer treatment. Stereotactic ablative brachytherapy (SABT) was designed to improve the ablative effect of radiation, which was achieved via improved image guidance, and calculation of ablative dose, shorter treatment duration, and better organ preservation. Recently collected data characterized SABT as having the potential to cure various early-stage cancers. The method provides higher tumor control rate levels that were previously achievable only by surgical resection. Notably, SABT is suitable for application with unresectable malignancies. However, the pathological assessment of SABT irradiated tumors is limited due to difficulties in specimen acquisition. Prostate, lung, liver, and gynecological cancers are the most commonly reported SABT-treated malignancies. This study will give an overview of SABT, focusing on the advances in SABT optimization, and provide insights on the future benefits of the combined application of SABT with cancer immunotherapies.

Iodine-125 radioactive seed brachytherapy as a treatment for spine and bone metastases: A systematic review and meta-analysis. Surg Oncol 2021; 38:101618. [PMID: 34153905 DOI: 10.1016/j.suronc.2021.101618] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 05/24/2021] [Accepted: 06/06/2021] [Indexed: 11/25/2022]
Abstract
AIM To evaluate the analgesic efficacy, safety, and local tumor control of iodine-125 (125I) seed brachytherapy (BT) for the management of spine and bone metastases. METHODS A systematic literature search was conducted using PubMed, the Cochrane Library, and Scopus databases. Data regarding patient demographics, tumor characteristics, procedural parameters, and clinical outcomes were extracted and analyzed. RESULTS Fourteen studies (7 prospective, 7 retrospective) were included, accounting for 689 patients, in our review. Analgesic efficacy was assessed at baseline and various postoperative time points. Significant improvement in pain was noted at 4- and 24-week follow-ups (p < 0.01). Interestingly, all studies that combined 125I seed BT with cement augmentation reported relatively higher levels of pain reduction (mean pain reduction ≥4 points) as compared to the studies which applied 125I seed BT as a stand-alone therapy (mean pain reduction ≥2 points), at the last follow-up. Local tumor control rates ranged widely from 14% to 100% at varying follow-ups. Median overall survival ranged between 10 months and 25 months. The overall complication rate was 19% (130/689) and mainly included minor subcutaneous hemorrhage, fever, myelosuppression, and seed displacement. Metrics assessing performance and quality of life demonstrated significant improvements from baseline to posttreatment. CONCLUSION 125I seed BT, alone or in conjunction with cement augmentation, may be a viable salvage therapy in appropriately selected patients. However, further studies are needed to analyze the long-term efficacy of this intervention as a palliative and curative modality.

Abstract
Radioactive seed brachytherapy is a method for treating drug-resistant, late-stage non-small cell lung cancer (NSCLC). To elucidate the mechanism of low-dose gambogic acid (GA) and NaI131 in drug-resistant NSCLC cells, the human NSCLC A549 cell line and the drug-resistant A549/cisplatin (DDP) and A549/Taxol cell lines were treated with NaI131, low-dose GA or a combination of both in the present study; the control group of each cell line was treated with phosphate-buffered saline (PBS). Following treatment, cell proliferation, apoptosis and cell cycle analysis was performed. Apoptosis-related proteins, namely CDK1, cyclin B, mutant p53 (mtp53), heat shock protein 90 (HSP90), Bax and Bcl-2, and P-glycoprotein 1 (P-gp), which is known to confer resistance to chemotherapy, were detected using western blotting and immunofluorescence analysis. mRNA levels of p53 and HSP90 were measured using reverse transcription-quantitative PCR. Compared with the PBS control group, the A549, A549/DDP and A549/Taxol cells treated with NaI131, GA or a combination of the drugs exhibited G2/M arrest and increased percentages of total apoptotic cells, as well as significantly decreased protein levels of CDK1, cyclin B, mtp53, HSP90, Bcl-2 and P-gp, increased protein levels of Bax and decreased mRNA levels of p53 and HSP90. The changes in the combination group were the most evident and were significantly different from the other groups (P<0.001). In conclusion, low-dose GA may be a potential radionuclide sensitizer.

Abstract
Purpose To evaluate the efficacy and safety of iodine-125 (125I) seeds implantation for inoperable early-stage non-small cell lung cancer (NSCLC). Material and methods PubMed, Cochrane Library, Embase, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched from inception until April 2020. Data were collected concerning overall survival, short-term efficacy, and complications. Meta-analysis was performed using R software (version 3.6.3). Results Nine studies involving 308 patients were included. Meta-analysis showed that the 1-, 2-, and 3-year survival rates were 0.98% (95% CI: 0.95-0.99%), 0.83% (95% CI: 0.77-0.89%), and 0.65% (95% CI: 0.55-0.75%), respectively; short-term local control rate (LCR) and effective rates were 0.99% (95% CI: 0.98-1.00%) and 0.92% (95% CI: 0.83-0.98%), respectively; 1-, 2-, and 3-year LCRs were 0.96% (95% CI: 0.83-1.00%), 0.94% (95% CI: 0.85-0.99%), and 0.95% (95% CI: 0.76-1.00%), respectively. Sub-group analysis of the prescribed dose found that when the prescribed dose was > 120 Gy, short-term efficacy and 1-year LCR were increased significantly (p < 0.01). The incidence of bleeding, pneumothorax, and radiation lung injury was 0.14% (95% CI: 0.07-0.21%), 0.19% (95% CI: 0.11-0.28%), and 0.00% (95% CI: 0.00-0.03%), respectively. Two studies involving 106 patients compared 125I seeds combined with chemotherapy versus chemotherapy alone for NSCLC. Results showed that compared with chemotherapy alone, 125I seeds combined with chemotherapy could improve short-term LCR (RR = 1.34, 95% CI: 1.09-1.65%, p = 0.005) and short-term effective rate (RR = 1.49, 95% CI: 1.14-1.96%, p = 0.004). Conclusions 125I seeds implantation is safe and effective approach for the treatment of inoperable early-stage NSCLC, but high-quality clinical research is still needed to further confirm the findings.

Abstract
Background The treatment of recurrent mediastinal lymph node metastasis (MLNMs) is challenging. We conducted this study to evaluate the effectiveness and safety of computed tomography (CT)‐guided percutaneous iodine‐125 brachytherapy for MLNMs. Methods We retrospectively analyzed 33 patients with recurrent MLNMs treated with CT‐guided interstitial implantation of iodine‐125 seeds. Regular contrast‐enhanced CT was conducted to evaluate the tumor response. Follow‐up survival, quality of life, and adverse events were analyzed. Results The number of implanted seeds was 16–85 (median, 40). The matched peripheral dose was 110–160 Gy. The patients were followed up for 5–24 months (median, 14 months). At the last follow‐up or death, complete response to therapy was achieved in 11 patients (33.3%) and partial response in 18 patients (54.5%). The median survival time of this cohort was 15.2 months (95% confidence interval [CI], 9.9–20.5 months); the estimated one‐ and two‐year survival rates were 68.6% and 31.1%, respectively. The Karnofsky performance score increased significantly after the procedure (p = 0.007). Pneumothorax with pulmonary compression of 30% to 40% occurred in five (15.2%) patients and was cured after drainage. No severe complications occurred. Conclusions CT‐guided iodine‐125 brachytherapy provided a safe and effective choice for recurrent mediastinal lymph node metastasis with significant local therapeutic effects and minor complications, especially for patients who were not eligible for surgical resection and had failed to benefit from systemic therapy.

Abstract
Introduction In recent years, radioactive 125I seed implantation combined with chemotherapy has been regarded as a safe and effective treatment for advanced non-small cell lung cancer (NSCLC). However, the mechanism underlying this success is still unclear. Methods In this study, we investigated the apoptosis and anti-proliferative effect induced by 125I in A549, H1975, and H157 cells and determined whether a sensitizing concentration of lobaplatin (LBP) could enhance these effects. We performed in vitro experiments on A549, H1975, and H157 cells; we investigated the effects of 125I or lobaplatin (LBP) alone, or in combination, on cellular apoptosis and proliferation by performing flow cytometry, Bax/Bcl2 ratio, TUNEL, cell viability assay, cell cycle, and EdU. To further verify our findings, a subcutaneous tumor mouse model was established. Moreover, AKT/mTOR pathway was detected to determine whether this pathway was involved in the anti-cancer effect of 125I and LBP by up-regulating or down-regulating the expression of mTOR. Results Based on our results, the sensitizing concentration of LBP could enhance the 125I-induced apoptosis and anti-proliferation effect. Furthermore, the subcutaneous tumor mouse model obtained the consistent results. More importantly, the AKT/mTOR pathway was down-regulated after the treatment of 125I and LBP, and the anti-cancer effect of 125I and LBP could be compromised by up-regulating the mTOR expression. Conclusion Our study proved that LBP promotes the apoptotic and anti-proliferative effects of 125I in NSCLC cells by inhibiting the AKT/mTOR pathway and provides a foundation for future studies and enhanced combinatorial approaches for NSCLC in the clinical setting.

Abstract
Brachytherapy (BT) is a minimally invasive anticancer radiotherapeutic modality where the tumor is directly irradiated via a radioactive source that is precisely implanted in or adjacent to the tumor. BT for lung cancer may be conducted in the form of endobronchial BT and radioactive seed implantation (RSI-BT), mainly for nonsmall cell lung cancer (NSCLC). For patients with early-stage lung cancer who are not suitable for surgery or external beam radiotherapy (EBRT), BT may be used as an alternative treatment, and curative results could be achieved in certain patients with cancer confined to the trachea lumen. For patients with locally advanced/metastatic lung cancer, BT could be selectively applied alone or as a boost to EBRT, which could improve the local tumor control and patient's survival. In addition, BT is also useful as a salvage treatment in select patients with locally recurrent/residual lung cancer that failed other treatments (e.g., surgery, chemotherapy, and EBRT). However, clinical outcomes are mainly obtained from retrospective studies. Prospective studies are limited and needed. In recent years, the introduction of modern image guidance, novel radioactive seeds, BT treatment planning systems (BT-TPS), after-loading technique, and three-dimensional printing template (3D-PT) assistance, among others, have potentially improved the clinical outcomes of BT. However, a comprehensive review of BT with newly published literature was lacking. This review is to discuss BT for NSCLC based on recent literature published in PubMed.

An iodine-125 seed strand combined with a metal stent versus a metal stent alone for obstructive jaundice caused by pancreatic ductal adenocarcinoma. Brachytherapy 2020; 20:446-453. [PMID: 33309002 DOI: 10.1016/j.brachy.2020.10.004] [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: 05/26/2020] [Revised: 08/21/2020] [Accepted: 10/15/2020] [Indexed: 11/18/2022]
Abstract
PURPOSE The purpose of this study was to assess the efficacy of an iodine-125 (125I) seed strand combined with a metal stent compared with a metal stent for treatment of obstructive jaundice caused by pancreatic ductal adenocarcinoma (PDAC). METHODS AND MATERIALS A retrospective analysis was carried out of patients who were referred to Shanghai Zhongshan Hospital of Fudan University with a diagnosis of PDAC between January 1, 2010 and January 31, 2019. A total of 110 consecutive patients with obstructive jaundice caused by PDAC were divided into the iodine-125 seed strand combined with a metal stent group (Group A = 48) and the metal stent group (Group B = 62). The primary outcome was stent obstruction-free survival time, and secondary outcomes were overall survival and complications. RESULTS The median stent obstruction-free survival time was 133.0 (95% confidence interval (CI): 166.093-149.907) days, and the median overall survival was 212.0 (95% CI: 187.183-236.817) days in all patients. Median stent obstruction-free survival time was 175 days (95% CI 103.165-246.835 days) in Group A versus 120 days (95% CI 87.475-152.525 days) in Group B (p = 0.035). A lower Eastern Cooperative Oncology Group (ECOG) score (p = 0. 000) and iodine-125 seed strand combined with metal stent implantation (p = 0.008) were associated with a longer stent obstruction-free survival time. Obstruction length (p = 0.083), ECOG score (p = 0.000), and iodine-125 seeds (p = 0.037) might have potential impact on stent obstruction-free survival time and were included for multivariable analysis using the Cox proportional hazards model. Stent restenosis was observed in 18.8% (9/48) of patients in Group A and 54.8% (34/62) in Group B, respectively. There was no significant difference in median survival between Group A and Group B (p = 0.409). The median survival in Group A was 209 days (95% CI 150.750-267.250) and 202 days (95% CI 190.624-233.376) in Group B. The median survival of patients with a lower ECOG score was better than that of patients with a higher ECOG score (267 days vs 132 days, p = 0.000). The Grade 3 or 4 complications occurred in 4 (8.3%) of the 48 patients in Group A (one case of hemobilia, one case of liver abscess, two cases of choleperitonitis) and in 5 (8.1%) of the 62 patients in Group B (one case of hemobilia, two cases of liver abscess, two cases of choleperitonitis) (p = 0.972). CONCLUSIONS Implantation of an iodine-125 seed strand combined with a metal stent provides longer obstruction-free survival time compared with a metal stent in patients with obstructive jaundice caused by PDAC. It seems reasonable to choose an iodine-125 seed strand combined with a metal stent as a treatment for these patients.

Improved prognosis for recurrent epithelial ovarian cancer by early diagnosis and 125I seeds implantation during suboptimal secondary cytoreductive surgery: a case report and literature review. J Ovarian Res 2020; 13:141. [PMID: 33250044 PMCID: PMC7702710 DOI: 10.1186/s13048-020-00744-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 11/16/2020] [Indexed: 12/17/2022] Open
Abstract
Background Epithelial ovarian cancer (EOC) has the worst prognosis in all of gynecologic malignant tumors because of its high recurrence and eventually chemo-resistance. Early diagnosis of recurrence is crucial to avoid diffuse dissemination. Failure of traditional treatment in recurrent epithelial ovarian cancer remains a challenge for clinicians. On the other hand, 125I brachytherapy has been accepted as a useful and hopeful treatment for multiple advanced cancers in recent years. However, its success in advanced epithelial ovarian cancer is limited. Here we report a case of recurrent ovarian cancer who had been early diagnosis of isolated recurrence and successfully treated with 125I seeds implantation during suboptimal cytoreductive surgery. Case presentation A 59-year-old woman presented with recurrent epithelial ovarian cancer who have had a history of ovarian cancer stage IIIB and an R0 resection had been achieved nearly 2 years before presented in our hospital. She underwent suboptimal secondary cytoreductive surgery after four cycles of chemotherapy with little effectiveness and severe chemotherapy-related side effects. Approximately 70% of the cancer-bulk was resected during surgery. For residual lesion which fixed around the right ureter and right external iliac vessel, 125I seeds implantation was performed. Postoperatively, the patient was treated with two cycles of combination chemotherapy with paclitaxel and carboplatin. The patient was free of disease at 26 months’ follow-up period. Conclusion In recurrent EOC patients with unresectable isolated lesion, salvage 125I seeds implantation are feasible and may contribute to survival.

Cancer Manag Res 2020; 12:8209-8220. [PMID: 32982417 PMCID: PMC7494957 DOI: 10.2147/cmar.s267694] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 08/19/2020] [Indexed: 12/15/2022] Open
Abstract
Background A proportion of patients with synchronous oligometastatic non-small cell lung cancer (NSCLC) have poor survival, and currently no standard treatment is available, which poses a great challenge to physicians. This study aimed to assess and compare the efficacy and safety of the combination of brachytherapy with iodine-125 seeds and systemic chemotherapy versus systemic chemotherapy alone for synchronous extracranial oligometastatic NSCLC. Materials and Methods After a systematic retrospective review of the case database between 1st Mar 2014 and 30th Mar 2018, data were obtained on 69 NSCLC patients with extracranial oligometastatic NSCLC. Among them, 32 patients received brachytherapy with iodine-125 seeds combined with systemic chemotherapy (group A), and the remaining 37 patients received chemotherapy alone (group B). The primary endpoint was overall survival (OS), and the secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and complications. Results The demographic and clinical characteristics were not significantly different between the groups (all p>0.05). The overall 3-month ORR was significantly higher in group A (65.6% vs 37.8%, p=0.030) than in group B. With a median follow-up time of 23 months, the PFS and OS were 11.6 (95% CI: 7.0–16.2) months vs 6.3 (95% CI: 3.4–9.2) months (p=0.036) and 17.6 (95% CI: 13.9–21.3) months vs 11.2 (95% CI: 7.7–14.7) months (p=0.042) in groups A and B, respectively. Furthermore, in Cox regression analysis, local brachytherapy was an independent prognostic factor for both PFS (HR=0.416, 95% CI: 0.246–0.702, p=0.001) and OS (HR=0.375, 95% CI: 0.216–0.653, p=0.001). Severe complications were not observed in either of the groups. Conclusion The combination of brachytherapy with iodine-125 seeds and systemic chemotherapy is superior to chemotherapy alone for synchronous extracranial oligometastatic NSCLC.

Abstract
BACKGROUND Non-small-cell lung cancers (NSCLCs) are only eligible to undergo curative surgical resection in <20% of patients. In patients with inoperable NSCLC, computed tomography (CT)-guided radioactive seed insertion (RSI) is a common treatment practice. OBJECTIVES To assess the relative efficacy of chemotherapy alone versus chemotherapy in combination with CT-guided RSI in patients with advanced NSCLC. METHODS We searched the Pubmed, Embase, and Cochrane Library databases for relevant articles published as of July 2020. Complete and total response rates (CR and TR, respectively) served as the primary endpoints for this meta-analysis, with disease control (DC) rate, myelosuppression rate, progression-free survival (PFS), overall survival (OS), and CT-guided RSI-related pneumothorax serving as secondary endpoints. RESULTS In total, eight studies incorporating 281 patients that underwent combination treatment and 297 patients that underwent chemotherapy along were included in this meta-analysis. The CR (21.5% vs. 4.0%, P < 0.00001), TR (73.8% vs. 42.6%, P < 0.00001), and DC (94.1% vs. 78.2%, P < 0.00001) rates were significantly higher for patients in the combined treatment group relative to patients in the chemotherapy only group. Furthermore, pooled PFS (P < 0.00001) and OS (P = 0.0006) were significantly longer for patients in the combined treatment group, whereas no differences in pooled myelosuppression rates were observed between groups (34.3% vs. 30.7%, P = 0.47). The pooled rate of CT-guided RSI-related pneumothorax was 15%. CONCLUSIONS Combination chemotherapy and CT-guided RSI can significantly improve clinical response and prolong survival in advanced-stage NSCLC patients without inducing other significant toxic side effects.

Abstract
Background The prognosis of patients with progressive or recurrent high-grade gliomas (HGGs) after surgery remains poor. Iodine-125 brachytherapy is emerging as a salvage method for the treatment of gliomas. This study aimed to investigate whether permanent iodine-125 brachytherapy could be used as an effective therapeutic method even without radiotherapy and/or chemotherapy for progressive or recurrent HGG after gross total resection. Methods Between March 2004 and August 2016, 58 patients with progressive or recurrent HGG after gross total resection were included in this study. Twenty-nine patients underwent radiotherapy and/or chemotherapy and then permanent iodine-125 brachytherapy (SRCI group). Twenty-nine patients underwent permanent iodine-125 brachytherapy alone (SI group). Follow-up was carried out at 1, 3, and 6 months and then at 1, 2, 3, and 5 years after iodine-125 implantation. The median overall survival (OS) and progression-free survival (PFS), procedure-related complications and clinical outcomes were evaluated. Results No procedure-related fatal events happened. The temporary morbidity rate was 11.9%. The median OS and PFS for patients in the SI group were 22 and 8 months compared with 21 and 7 months in the SRCI group. No significant differences were found. Age and Karnofsky Performance Status (KPS) were independent prognostic factors for OS. Age, KPS and histology were independent prognostic factors for PFS. Conclusions Permanent iodine-125 brachytherapy could be used as an effective therapeutic method even without radiotherapy and/or chemotherapy for progressive or recurrent HGG after gross total resection.

Abstract
OBJECTIVES To evaluate the efficacy and safety of the combination of computed tomography (CT)-guided iodine-125 brachytherapy and bronchial arterial chemoembolization (BACE) for locally advanced stage III non-small cell lung cancer (NSCLC) after failure of concurrent chemoradiotherapy. MATERIAL AND METHODS We retrospectively evaluated 28 patients with locally advanced stage III NSCLC in whom concurrent chemoradiotherapy had failed and were consequently, treated with radioactive iodine-125 seed implantation followed by BACE. The prescribed radiation dose was 140 Gy, with a median radioactivity of 0.60 mCi. The tumor-feeding arteries were detected on angiography, and chemotherapeutic agents (gemcitabine 1000 mg/m2 + lobaplatin 30 mg/m2) were then administered via arterial infusion. The tumor-feeding arteries were embolized using 300-500 μm embosphere microspheres. The endpoints were treatment response rate, progression-free survival (PFS), and toxicity. RESULTS The median number of implanted iodine-125 seeds was 58 pellets (range, 44-114 pellets). The median post-operative dose covering 90 % of the target volume (D90) was 143.4 Gy (range, 123.6-159.9 Gy). A total of 73 cycles of BACE were conducted (2.61 cycles per case). The bronchial arteries were the main tumor-feeding arteries. In total, 11 patients had hemoptysis, and it was significantly alleviated within 24 h after BACE. There was no serious procedure-related complication. The 6-month objective response and disease control rates were 71.42 % and 92.86 %, respectively. No severe complications occurred during the follow-up. Local control duration ranged from 5-12 months, and the median PFS was 8 months (95 % confidence interval: 7.3-8.8 months). CONCLUSIONS The combination of CT-guided iodine-125 brachytherapy and BACE is an effective and safe approach for the treatment of NSCLC after failure of concurrent chemoradiotherapy and is worthy of clinical application.

Abstract
Non-small cell lung cancer (NSCLC) has become the most common cancer type and the leading cause of cancer-associated mortality worldwide. The aim of the present retrospective study was to evaluate the efficacy and safety of computed tomography (CT)-guided 125I brachytherapy alone in elderly patients with NSCLC. A total of 26 elderly patients with NSCLC stage I–III who had an inoperable lesion or progressive disease following radio-chemotherapy were treated with CT-guided 125I seed implantation for lung lesions and included in the present study. The prescribed dose of 125I brachytherapy was 80–140 Gy, and dosimetric verification was performed immediately after the procedure. The response rate (RR) and local control rate (LCR) were analyzed according to the Response Evaluation Criteria in Solid Tumors (version 1.1). Survival was estimated using the Kaplan-Meier method. Safety and complications were also documented. All patients were aged 65–85 years (median age, 77 years) and successfully completed the procedure, and the median follow-up time was 9.4 months (range, 3–31 months). After a 6-month follow-up, for pulmonary lesions, complete response (CR) was achieved in 11 (42.3%) cases, partial response in 9 (34.6%) cases, stable disease in 4 (15.4%) cases and progressive disease in 2 (7.7%) cases. The 6-month RR and LCR were 76.9 (20/26) and 92.3% (24/26), respectively. The mean overall survival (OS) time was 11.7±7.6 months and the 0.5- and 1-year OS rates were 90.1 and 73.3%, respectively. Tumor-related symptoms in patients were significantly alleviated following the procedure. No severe complications occurred during and after the procedure of 125I seed implantation. In conclusion, CT-guided 125I brachytherapy is a feasible, effective and safe therapy and may be considered as an alternative option to surgery and radiotherapy for elderly patients with NSCLC.

Abstract
BACKGROUND A significant number of developing countries have no facilities to produce medical radioisotopes and radiopharmaceuticals. OBJECTIVE In this paper we show that access to life-saving radioisotopes and radiopharmaceuticals and the geographical distribution of corresponding infrastructure is highly unbalanced worldwide. METHODS We discuss the main issues which need to be addressed in order to establish the production of radioisotopes and radiopharmaceuticals, which are especially important for developing countries as newcomers in the field. The data was gathered from several sources, including databases maintained by the International Atomic Energy Agency (IAEA), World Health Organization (WHO), and other international organizations; personal interactions with representatives in the nuclear medicine field from different regions of the world; and relevant literature. RESULTS Developing radioisotope and radiopharmaceutical production program and installing corresponding infrastructure requires significant investments, both man-power and financial. Support already exists to help developing countries establish their medical radioisotope production installations from several organizations, such as IAEA. CONCLUSION This work clearly shows that access to life-saving radioisotopes and the geographical distribution of corresponding infrastructure is highly unbalanced. Technology transfer is important as it not only immediately benefits patients, but also provides employment, economic activity and general prosperity in the region to where the technology transfer is implemented.

Thorac Cancer 2020; 11:697-703. [PMID: 31995853 PMCID: PMC7049489 DOI: 10.1111/1759-7714.13320] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Revised: 01/01/2020] [Accepted: 01/01/2020] [Indexed: 12/11/2022] Open
Abstract
Background Salvage treatments for recurrent NSCLC after first‐line chemotherapy remain challenging. This study was conducted to evaluate the clinical value of microwave ablation (MWA) and iodine‐125 brachytherapy, including overall survival (OS), disease free survival (DFS), local control, hospital stay, and health economics. Methods The data of 51 and 32 patients who were treated with MWA and brachytherapy was retrospectively analyzed. The number of lesions was limited up to two, with a diameter <4 cm and patients diagnosed with unilateral lung disease. Peripheral tumors were treated with MWA, while lesions close to the hilum were treated with brachytherapy. Contrast‐enhanced CT, blood cell count, coagulation function, liver & kidney function and tumor markers were performed for two years, with complications calculated. OS, DFS, local control rate, toxicity, hospital stay and expense were recorded. Results The one and two‐year OS rates were 96.08% and 92.16% versus 96.88% and 90.62% in the MWA and brachytherapy groups, respectively. The one and two‐year DFS rates were 92.16% and 76.47% versus 93.75% and 78.13%, respectively. No significant differences were observed in log‐rank analysis between the groups. Local control rates at six and 12 months were 100% and 96.08% versus 100% and 96.88%, while incidences of pleural effusion were 3.92% and 3.13%, respectively (P < 0.05). Medical cost was 3356.73 ± 206.87 and 6714.28 ± 35.43 U.S. dollars (P = 0.014). Conclusion MWA and brachytherapy are effective and safe options for the treatment of NSCLC recurrence after first‐line chemotherapy. Which modality should be considered is dependent upon tumor location, tumor size and experience of specialists.

Abstract
OBJECTIVE To examine the imaging capability of a novel small field of view hybrid gamma camera (HGC) using 125I seeds prior to surgical use. METHODS The imaging performance of the camera system was assessed quantitatively and qualitatively at different source depths, source to collimator distances (SCD), activity levels, acquisition times and source separations, utilising bespoke phantoms. RESULTS The system sensitivity and spatial resolution of the HGC for 125I were 0.41 cps/MBq (at SCD 48 mm) and 1.53 ± 0.23 mm (at SCD 10 mm) respectively. The camera was able to detect the 125I seed at a SCD of 63 mm (with no scattering material in place) in images recorded within a 1-min acquisition time. The detection of the seeds beneath scattering material (simulating deep-seated tumours) was limited to depths of less than 20 mm beneath the skin surface with a SCD of 63 mm and seed activity of 2.43 MBq. Subjective assessments of the hybrid images acquired showed the capability of the HGC for localising the 125I seeds. CONCLUSION This preliminary ex vivo study demonstrates that the HGC is capable of detecting 125I seeds and could be a useful tool in radioactive seed localisation with the added benefit of providing hybrid optical γ images for guiding breast conserving surgery. ADVANCES IN KNOWLEDGE The SFOV HGC could provide high resolution fused optical-gamma images of 125I radioactive seeds indicating the potential use in intraoperative surgical procedure such as RSL.

Abstract
Objective To investigate the rule of kidney-tonifying method in Chinese medicine for the treatment of bone marrow suppression (BMS), in order to provide evidence and references for the clinical application of herbs and formulae. Design Collecting and sorting the information about the treatment of BMS related to kidney-tonifying (Bushen) method in Chinese medicine literatures on databases including Chinese National Knowledge Infrastructure (CNKI), and Chinese Biomedical Literature Database (CBM), establishing a database of BMS treating formulae after radiotherapy and chemotherapy with traditional Chinese medicine (TCM) kidney-tonifying method, and finally applying the relevant theories and techniques of data mining to analyze the medication rules of it. Results A total of 239 formulae and 202 herbs were included in this database, in which the herbs occurred 2,602 times in general. The high frequency herbs included Astragali Radix (Huangqi), Atractylodis Macrocephalae Rhizoma (Baizhu), and Ligustri Lucidi Fructus (Nvzhenzi). The main herb categories were deficiency-tonifying herbs, blood-activating herbs, dampness-draining diuretic herbs, heat-clearing herbs, and digestant herbs. Deficiency-tonifying herbs accounted for 64.60% of the total number. A total of 8 clustering formulae are summarized according to cluster analysis and 26 herb suits association rules are identified by Apriori algorithm. Conclusion The treatment of BMS is mainly based on the method of invigorating the spleen and tonifying the kidney and liver to strengthen healthy qi, supplementing with blood-activating herbs, and dampness-draining diuretic herbs to eliminate pathogenic factors.

Abstract
Dental pulp stem cell (DPSC) transplantation has been demonstrated to promote the regeneration and repair of tissues and organs and is a potentially effective treatment for radioactive esophageal injury. In this study, to explore the therapeutic effects of DPSCs on acute radiation-induced esophageal injury, DPSCs were cultured and transplanted into rats with acute radioactive esophageal injuries induced by radioactive 125I seeds in vivo. In the injured esophagus, PKH26-labeled DPSCs co-localized with PCNA, CK14, CD71, and integrin α6, and the expression levels of these four makers of esophageal stem cells were significantly increased. After DPSC transplantation, the injured esophagus exhibited a greater thickness. In addition, the esophageal function and inflammation recovered faster. The results demonstrated that transplanted DPSCs, which trans-differentiated into esophageal stem cells in vivo, could repair the damaged esophageal tissue.

Malignant obstructive jaundice treated with intraluminal placement of Iodine-125 seed strands and metal stents: An analysis of long-term outcomes and prognostic features. Brachytherapy 2018; 17:689-695. [PMID: 29748084 DOI: 10.1016/j.brachy.2018.04.001] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2017] [Revised: 03/15/2018] [Accepted: 04/03/2018] [Indexed: 02/06/2023]
Abstract
PURPOSE The purpose of this study was to analyze the long-term outcomes, including safety, efficacy, and prognostic features, of intraluminal brachytherapy with Iodine-125 (125I) seed strand and stent placement for treatment of patients with malignant obstructive jaundice (MOJ). METHODS AND MATERIALS From January 2009 to December 2013, 107 consecutive patients with MOJ were treated with intraluminal placement of 125I seed strands and metal stents. A retrospective evaluation of therapeutic outcomes, including overall survival (OS), stent patency rate, complications, and prognostic features, was conducted in 101 patients. RESULTS 125I seed strands and stents were all successfully implanted. The median followup time was 231 (45-1015) days, and the median OS was 394.0 (95% confidence interval: 319.1-468.9) days. The cumulative OS rates at 3, 6, 12, and 24 months were 95%, 77%, 53%, and 20%, respectively. The median stent patency period was 278.0 (95% confidence interval: 164.1-391.9) days, and cumulative patency rates at 3, 6, 12, and 24 months were 92%, 69%, 45%, and 13%, respectively. Multivariate analysis indicated that the serum conjugated/total bilirubin ≥88% before procedure (p = 0.032) and whether the patient receiving further treatment (p = 0.041) appear to be the prognostic factors of OS. There is no statistical prognostic factor for stent patency. CONCLUSIONS The intraluminal placement of 125I seed strands and stents appears to be a safe and efficient therapy on MOJ. The patient with serum conjugated/total bilirubin ≥88% before procedure and receiving further treatment seems to live longer.
