Abstract
Background Lung metastasis nodules and advanced-stage tumors are often considered inoperable conditions for thoracic surgery and remain major challenges to clinical decision-making. Brachytherapy has its advantages in treating localized solid tumors, which can be used in combination with other treatments to achieve good safety and efficacy. In this study, we aimed to determine the outcomes of patients who received a combination of standard chemotherapy and computed tomography (CT)-guided percutaneous brachytherapy treatment for advanced-stage lung malignant lesions. Methods We retrospectively collected data on patients with advanced lung cancer or lung metastasis nodules who underwent percutaneous CT-guided iodine-125 (125I) brachytherapy treatment. Patients were divided into two groups: Group A (brachytherapy with chemotherapy) and Group B (brachytherapy-only). Patients were reevaluated 1 month after the operation and then followed up every 3 months. The primary endpoint of this study was overall survival. Results Our results showed that the mean age in Group B was higher (62.32±8.79 years) than that of Group A (68.59±11.46 years; P=0.018). Patients receiving a combination of chemotherapy and brachytherapy had a median survival time of 20.5 months [95% confidence interval (CI), 16.5-24.5], while those receiving brachytherapy alone had a median survival time of 16.4 months (95% CI, 11.7-21.1) (P=0.026). Patients who received additional thermal ablation treatment and those who did not have median survival times of 16.4 (95% CI, 10.2-22.7) and 17.0 months (95% CI, 13.3-20.8) (P=0.607). The median survival time for patients with oligo lesions was 19.8 months (95% CI, 15.7-23.9), while it was 10.5 months (95% CI, 7.5-13.4) for those who had multiple lesions. Conclusions The combination of percutaneous CT-guided 125I brachytherapy and standard chemotherapy was superior to brachytherapy alone in terms of overall survival for patients with inoperable pulmonary lesions. Our results showed no benefit from additional adjuvant thermal ablation treatment. Patients with a single oligo nodule seem to have a better prognosis than those with multiple lesions.

Abstract
Surgical resection is still the standard treatment for early-stage lung cancer. A multimodal treatment consisting of chemotherapy, radiotherapy and/or immunotherapy is advised for more advanced disease stages (stages IIb, III and IV). The role of surgery in these stages is limited to very specific indications. Regional treatment techniques are being introduced at a high speed because of improved technology and their possible advantages over traditional surgery. This review includes an overview of established and promising innovative invasive loco-regional techniques stratified based on the route of administration, including endobronchial, endovascular and transthoracic routes, a discussion of the results for each method, and an overview of their implementation and effectiveness.

Safety and efficacy of stereotactic ablative brachytherapy as a salvage therapy for recurrent chest wall cancer: A retrospective, multicenter study. Front Oncol 2023; 12:957497. [PMID: 36824397 PMCID: PMC9942776 DOI: 10.3389/fonc.2022.957497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 12/30/2022] [Indexed: 02/09/2023] Open
Abstract
Purpose To evaluate the safety and efficacy of stereotactic ablative brachytherapy (SABT) as a salvage therapy for patients with recurrent chest wall cancer (rCWC) who have previously received external beam radiotherapy (EBRT) or surgery. Materials and methods Between November 2013 and October 2020, a total of 130 patients (including 75 men with a median age of 63 years) with rCWC treated with SABT were enrolled in this multicenter retrospective study. There were 97 cases of non-small-cell lung carcinoma, 24 cases of breast cancer, and 9 cases of thymic cancer. Of the patients included, 102 patients previously received surgery and 58 patients received EBRT, with systemic treatment progressing after recurrence. None of them were suitable or refused to undergo salvage EBRT or surgery again. Results During the 22 (4-70)-month median patient follow-up, 59 patients died. The local control (LC) rates at 6, 12, 24, and 36 months were 88.3%, 74.3%, 50.4%, and 36.7%, respectively. The 1-, 2- and 3-year survival rates were 85%, 56%, and 42%, respectively. The median overall survival was 26 months (95% CI, 18.9-33.1 months). The pain relief rate was 81%, and the median to remission time was 10 days. Univariate and multivariate analyses showed that independent prognostic factors for LC included tumor size and postoperative D90. On the other hand, independent prognostic factors for survival include the Karnofsky performance status (KPS) score, tumor size, and D90 19 patients (14.6%) developed grade I/II skin reaction complications. No grade III or severer complications occurred. Conclusion SABT is safe and effective as a salvage therapy for rCWC following EBRT/surgery. For patients with a KPS score greater than 80, prescribed dose greater than 130 Gy, and tumor size less than 4 cm may bring better results.

J Clin Lab Anal 2022; 36:e24714. [PMID: 36164726 DOI: 10.1002/jcla.24714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 09/06/2022] [Accepted: 09/12/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is one of the cancers with a high mortality rate. CircRNAs have emerged as an important regulatory factor in tumorigenesis in recent years. However, the detailed regulatory mechanism of a circular RNA cullin 2 (hsa_circ_0018189; hsa_circ_0018189) is still unclear in NSCLC. METHODS RNA levels of hsa_circ_0018189, microRNA (miR)-656-3p, and Solute carrier family seven member 11 (SLC7A11, xCT) were analyzed by real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR), and protein level was assessed by Western blot and immunohistochemical assay. Enzyme-linked immunosorbent assay was conducted to detect cell glutamine metabolism. Effects of hsa_circ_0018189 on cell proliferation, apoptosis, migration, and invasion were analyzed by corresponding assays. Luciferase reporter assay and RNA-immunoprecipitation assay confirmed the target relationship between miR-656-3p and hsa_circ_0018189 or xCT. The in vivo function of hsa_circ_0018189 was verified by xenograft mouse models. RESULTS Hsa_circ_0018189 abundance was overexpressed in NSCLC cells and samples. Deficiency of hsa_circ_0018189 lowered NSCLC cell proliferative, migrating, invading, and glutamine metabolism capacities, and hsa_circ_0018189 silencing inhibited the growth of tumors in vivo. Hsa_circ_0018189 could up-regulate xCT by sponging miR-656-3p. And miR-656-3p downregulation or xCT overexpression partly overturned hsa_circ_0018189 knockdown or miR-656-3p mimic-mediated repression of NSCLC cell malignancy. CONCLUSION Hsa_circ_0018189 drove NSCLC growth by interacting with miR-656-3p and upregulating xCT.

Abstract
Background Continuing therapy for aggressive non-small-cell lung cancer (NSCLC) after first-line treatment (FLT) is challenging. The clinical efficacy of second-line chemotherapy (SLCT) for progressive NSCLC is limited. In this meta-analysis, we aim to evaluate the clinical efficacy of the combination of I-125 seeds brachytherapy (ISB) and SLCT in progressive NSCLC after FLT. Methods The PubMed, Embase, Cochrane Library, CNKI, Wanfang, and VIP databases were screened for relevant publications until September 2021. Meta-analyses are conducted by RevMan 5.3 and Stata 12.0. Results Our meta-analysis encompassed 6 studies (4 retrospective studies and 2 randomized controlled trials), which included 272 patients that underwent ISB with SLCT (combined group) and 257 patients that received SLCT alone (chemotherapy alone group). The complete response (24.7% vs. 7.0%, P < 0.00001), treatment response (65.7% vs. 38.1%, P = 0.0002), and disease control (95.2% vs. 80.4%, P < 0.00001) rates are markedly elevated for patients receiving combined therapy versus those receiving chemotherapy alone. Moreover, pooled progression-free survival (P = 0.0001) and overall survival (P < 0.00001) were remarkably extended for patients that received the combination therapy, while no obvious differences were detected in the pooled myelosuppression (39.0% vs. 30.6%, P = 0.05) and gastrointestinal response (38.5% vs. 35.9%, P = 0.52) rates between 2 groups. Significant heterogeneity was found in the endpoints of the treatment response and progression-free survival. Conclusions This meta-analysis demonstrated that ISB could enhance the clinical efficacy of SLCT in patients with progressive NSCLC after FLT without inducing major toxic side effects.

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
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
PURPOSE This study aimed to investigate the therapeutic potential of tumor suppression and mechanism for different implantation modes of iodine-125 (I-125) seeds irradiation in a mice xenograft model, and its skeletal complications. MATERIALS AND METHODS A total of 24 mice carrying A549 lung tumor-derived xenografts were randomly assigned to four groups, including non-radioactive (sham) seeds implantation, I-125 seeds fractional implantation, I-125 seeds single implantation and I-125 seeds single implantation combined with anlotinib. Ki67 immunohistochemistry, TUNEL immunofluorescence and CD31 morphometric analysis were used to determine the proliferation index, rate of apoptotic cells and microvessel density, respectively. Additionally, the side effects on the skeletal system in mice treated with I-125 seeds implantation were evaluated by histomorphometric staining with tartrate-resistant acid phosphate (TRAP) and alkaline phosphatase (ALP) expression in femur, tartrate-resistant acid phosphatase 5b (TRACP-5b) and procollagen type I N-terminal propeptide (PINP) levels in serum were evaluated by enzyme-linked immunosorbent assay (ELISA). RESULTS The I-125 seeds single and fractionated implantation had similar therapeutic effects and complications when the total number of I-125 seeds was the same. A single implantation of I-125 seeds with or without anlotinib could analogously inhibit the tumor growth in xenografts mice, while the single implantation combined with anlotinib had more effective in tumor inhibition. The results of Ki67, TUNEL and CD31 staining confirmed an evident reduction in tumor cell proliferation and angiogenesis, as well as an increase in apoptosis. A relatively integrated bone metabolism was indicated after I-125 seeds single implantation with or without anlotinib, and the results were similar in I-125 seeds fractional implantation, including a reduction in the number of TRAP-positive cells and an increase in ALP expression level. Additionally, the serum TRACP-5b activity was decreased and the serum PINP concentration was increased following I-125 seeds implantation. CONCLUSIONS Single and fractionated implantation pattern of I-125 radioactive seeds had similar therapeutic efficacy against tumor growth, while brachytherapy with I-125 seeds implantation may be an effective and safe treatment strategy for its potential protection against cancer treatment-induced bone loss.

[PMID: 34487634 PMCID: PMC8504606 DOI: 10.1002/acm2.13419] [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: 06/10/2021] [Revised: 07/16/2021] [Accepted: 08/23/2021] [Indexed: 12/18/2022] Open
Abstract
Introduction The purpose of this study was to verify the effectiveness of polylactic acid (PLA) template puncture route planning by comparing preoperative and postoperative dosimetry using computerized tomography (CT)‐guided implantation of 125I radioactive seeds. Methods A total of 28 patients who underwent 125I seed implantation between January 2018 and June 2019 were selected for the statistical study of seed dosimetry. All patients received preoperative treatment planning system (TPS) planning, of which 13 patients in the experimental 3D template group underwent intraoperative puncture and implantation using the PLA template planning route. The other 15 patients in the traditional control group underwent intraoperative puncture and implantation using CT images for guidance. By calculating the dose‐volume histogram, preoperative and postoperative D90 values and postoperative V90 values were compared between the two groups. Results The mean D90 values in the template group before and after surgery were 136.06 ± 7.10 and 134.72 ± 7.85 Gy, respectively. There was no statistically significant difference. The preoperative and postoperative mean D90 values in the traditional group were 132.97 ± 8.04 and 126.06 ± 9.19 Gy, respectively, which were statistically significantly different. The mean postoperative V90 values in the template and traditional groups were 93.80 ± 1.34% and 88.42 ± 6.55 %, respectively, showing a statistically significant difference. Conclusions The preoperative TPS plan for the experimental group guided by the PLA template was almost the same as that for the final guided particle implantation. The dose parameters in the experimental group were also better than those in the traditional group, making the use of the presented PLA template more efficient for clinical applications.

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.

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 The aim of this study was to compare the effectiveness and safety of CT-guided 125I seed brachytherapy combined with single-agent chemotherapy versus combined chemotherapy in the treatment of elderly NSCLC. Materials and Methods We retrospectively analyzed 110 patients (64 men and 46 women; mean age=71.25±7.14 years) who were diagnosed with NSCLC without distant metastases between January 2015 and May 2020. A total of 50 patients received 125I brachytherapy combined with single-agent chemotherapy (group A), whereas 60 patients received combined chemotherapy (group B). The response to therapy and adverse effect were compared between groups. The local response rate was evaluated by CT. Progression-free survival (PFS) and overall survival (OS) data were obtained through clinical follow-up. Results All patients had been treated and were followed-up for 3-60 months. The median OS and PFS were 23.71±1.41 months (95% CI=20.95-26.47) vs 16.12±0.93 months (95% CI=14.31-17.93) (P<0.05) and 15.08±0.85 months (95% CI=13.42-16.74) vs 10.03±0.53 months (95% CI=9.01-11.06) (P<0.05) in group A and group B, respectively. The local response rate and clinical symptoms of patients in group A were significantly relieved when compared with group B. Severe complications were not observed in either group. Conclusion CT-guided 125I seed brachytherapy combined with single-agent chemotherapy is an effective and safe therapy and shows promising results compared to combined chemotherapy alone for NSCLC in the elderly. A randomized study will be needed to assess the superiority of this combined modality treatment.

Abstract
Background Recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) is a difficult challenge for physicians, especially when patients have been treated with external beam radiotherapy. The purpose of this study was to assess the clinical efficacy and safety of computed tomography (CT)-guided iodine-125 brachytherapy as a palliative treatment for R/M HNSCC. Methods From May 2011 to July 2018, we enrolled 87 patients with R/M HNSCC who had previously received external beam radiotherapy. Among these patients, 43 successfully underwent CT-guided iodine-125 brachytherapy and chemotherapy (group A); 44 patients who only received chemotherapy (group B) were matched with patients in group A. Patients' pain score, Eastern Cooperative Oncology Group (ECOG) score, tumor compression symptoms, and side effects of iodine-125 implantation were recorded. Clinical follow-up was performed to assess progression-free survival (PFS) and overall survival (OS). Results Both groups of patients completed the treatment and were followed up for 9-66 months, with a median follow-up time of 44 months. The OS was 51 months (95% CI: 42.93-59.06 months) versus 28 months (95% CI: 23.79-32.21 months) (p < 0.05), the PFS was 10 months (95% CI: 6.15-13.84 months) versus 6 months (95% CI: 4.40-7.59 months) (p < 0.05) in groups A and B, respectively. The RR in group A was 25/43 (58.14%) versus 15/44 (34.10%) in group B (p < 0.05). Compared with group B, patients in group A had lower pain scores, better physical performance, and better improvement of compression symptoms. No serious treatment-related complications were observed in either group of patients. Conclusion Compared with chemotherapy alone, iodine-125 seed implantation combined with chemotherapy was a more effective and safer strategy for R/M HNSCC.

Abstract
Background To analyze the efficacy of computed tomography (CT)-guided implantation of 125I radioactive particles in treatment of early lung cancer. Methods Six patients were analyzed, including 4 squamous cell carcinoma, 1 adenocarcinoma, and 1 small cell lung cancer. TPS software was used to calculate the therapeutic dose amount of particles implanted, and the spacing and distribution of seeds in the target area and adjacent tissues. Under the guidance of CT, 20–55 particles were implanted at each site, with the total number of radioactive particles being 226, the particle spacing being 0.5–1.0 cm, and the implantation being performed in accordance with the principle of uniform implantation. The patients were each followed up with repeated pulmonary CT scans at 1, 3, 6, 12, 18, 24, 30 and 36 months after the procedure. In accordance with the response evaluation criteria in solid tumors (RECIST), the following definitions for responses were used: complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD). Results There were 2 CRs and 4 PRs one month after procedure; six patients were followed up 3 months after procedure, including 2 CRs and 4 PRs; one patient was lost in follow-up, and 5 patients were followed up 6 months after procedure, including 3 CRs and 2 PRs; five patients were followed up 12 months after procedure, including 3 CRs, 1 PR and 1 PD. The single PD patient was again given CT-guided implantation of 125I radioactive particles for the treatment of recurrent lesions. The pulmonary CT was repeated 6 months after procedure, and the response was evaluated as SD. Four patients were followed up 18 months after procedure, including 3 CRs and 1 PR; one patient was lost in follow-up and 3 patients were followed up 24 months after the procedure with the response being evaluated as CR for all of them; one patient was followed up 36 months after procedure, and the response was evaluated as PD. During the follow-up, no serious complications occurred in any of the patients. Conclusions The preliminary clinical observation showed that 125I radioactive particle implantation was a safe, reliable and effective therapeutic method for early lung cancer.

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
Aims This study aims to observe the preliminary clinical efficacy of percutaneous interstitial brachytherapy using iodine-125 seeds for the treatment of advanced malignant lung tumors. Subjects and Methods This retrospective study enrolled 24 patients in our hospital with advanced malignant lung tumors between June 2013 and November 2017. Computed tomography (CT)-guided iodine-125 seed implantation therapy was administered to these patients. All patients were followed up at 3, 6, and 12 months after the operation. The clinical efficacy was evaluated by CT. Results Among the 24 patients, the objective response rates at 3, 6, and 12 months after the procedure were 50.0%, 50.0%, and 33.3%, respectively. Recent occurrence of adverse reactions were observed, including four cases of pneumothorax, three cases of hemoptysis, and two cases of particle displacement. Conclusions CT-guided percutaneous interstitial brachytherapy with iodine-125 seeds can be used for the treatment of lung malignant tumors. Its clinical curative effect is remarkable and it results in limited trauma, reducing the incidence of adverse reactions and improving patient quality of life.

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.

Safety and efficacy of CT-guided radioactive iodine-125 seed implantation assisted by a 3D printing template for the treatment of thoracic malignancies. J Cancer Res Clin Oncol 2019; 146:229-236. [PMID: 31630263 DOI: 10.1007/s00432-019-03050-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2019] [Accepted: 10/04/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To ascertain the safety and efficacy of radioactive iodine-125 seed implantation (RISI) for the treatment of thoracic tumors. METHODS Clinical patients with primary or metastatic tumors in the chest treated with RISI were analyzed. The RISI process included the following stages: preoperative planning, template design and 3D printing, CT-guided RISI assisted by a template, and postoperative dosimetric verification. The prescribed dose was ≥ 80 Gy. The main analytic measures were the local control (LC) rate and toxicity. RESULTS From April 2015 to July 2018, a total of 92 patients, including 41 with lung cancer and 51 with lung metastases, were analyzed. The median lesion diameter was 5 cm. The median postoperative D90 was 142.6 Gy. The median follow-up was 10.7 months. The overall survival rates at 1 year and 3 years were 59.7% and 22.2%, respectively. The LC rates at 1 year and 3 years were 64.9% and 32.8%, respectively. The LC rates at 3 years for patients with D90 < 140 Gy and D90 > 140 Gy were 23.1% and 54.3%, respectively (P = 0.014). The LC rate of metastatic lung cancer was more favorable than that of primary lung cancer. The multivariate analyses showed that the dose and lesion type were independent factors for LC (P < 0.05). No factors were related to OS. The incidence of pneumothorax and hemoptysis was 35.8% and 3.2%, respectively. Few cases of radiotherapy-related toxicity effects were observed. CONCLUSIONS RISI may be safe and efficacious and is associated with few complications during the treatment of thoracic tumors. If patients need local treatment and surgery or radiotherapy is not available, RISI could be considered.

Abstract
Purpose The aim of the study was to determine how many times iodine-125 (125I) seed brachytherapy (ISB) for recurrent pulmonary metastases (RPM) can be done, and the clinical efficacy and complications of repeated ISB in RPM treatment. Material and methods Between September 2013 and August 2018, 18 patients with RPM, after conventional chemotherapy, radiotherapy, and trans-arterial chemoembolization, received CT-guided repeated ISB. Patients were followed up, and local control, survival, and post-operative complications were analyzed retrospectively. The Kaplan-Meier method was used for survival analyses. Results Eighty-two metastases in 18 patients were treated with ISB, with 71 implantations (mean number of implantations per patient, 4; range, 3-8). The total number of implanted 125I seeds was 1,220 (mean number per patient, 68; minimum, 40; maximum, 110). The mean value of D90 for ISB was 138 Gy. Local control was 91.46%, 90.24%, and 89.02% at 1, 3, and 6 months after ISB, respectively. After repeated ISB, good local control was achieved, and all patients were discharged from hospital within 3 days. One month after, six metastases of large diameter were treated with ISB; computed tomography revealed level 1 radioactive injury to the lungs, but special treatment was not administered. Post-operative renal, hepatic, and vascular functions were normal. Conclusions ISB for RPM is safe and efficacious. RPM treatment seems not to be limited by number of times ISB could be repeated; at least up to 8 times for different sites of lung.

Abstract
Surgery remains the first choice of cure for early stage lung cancer. However, many patients are diagnosed at advanced stage, and thus miss the opportunity to undergo surgery. As such patients derive limited benefits from chemotherapy or radiotherapy, alternatives focusing on local control have emerged, including iodine-125 seed implantation. The Interstitial Brachytherapy Society, Committee of Minimally Invasive Therapy in Oncology, Chinese Anti-Cancer Association organized a group of multidisciplinary experts to develop guidelines for this treatment modality. These guidelines aim to standardize iodine-125 seed implantation procedures, inclusion criteria, and outcome assessment to prevent and manage procedure-related complications.

Abstract
BACKGROUND Iodine-125 interstitial brachytherapy (125I-IBT) is a promising treatment option for unresectable hepatocellular carcinoma (HCC). This study evaluated the usefulness of micro-positron emission tomography/computed tomography (micro-PET/CT) with 18F-fluorodeoxyglucose (18F-FDG) in assessing response to 125I-IBT in HCC HepG2 xenograft. MATERIAL AND METHODS Twelve mice with bilateral HepG2 xenografts were divided into 3 equal groups implanted with iodine-125 seeds into the left xenografts with a dose of 30, 50, and 80 Gy, respectively, and the right xenografts were used as internal controls. Before and 28 days after treatment, the 18F-FDG micro-PET/CT was performed. The ratios of left to right xenografts of tumor volume (RTV), maximum standardized uptake value (RSUVmax), mean optical density of caspase-3 expression (RMODcaspase-3), and apoptosis index (RAI) were compared. RESULTS The RTV means of the 50 and 80 Gy groups were significantly lower than in the 30 Gy group after treatment (P<0.01) and the RTV means after treatment were lower than baseline in the 50 and 80 Gy groups (P<0.05). The RSUVmax mean after treatment was lower than baseline in the 80 Gy group (P<0.05). The RMODCaspase-3 and RAI means of the 80 Gy group were higher than in the 30 Gy group (P<0.05). The RSUVmax was correlated negatively to RMODcaspase-3 (r=-0.624, P<0.05) and RAI (r=-0.651, P<0.05). CONCLUSIONS This study suggest that 125I-IBT inhibits tumor growth via upregulating caspase-3 expression and prompting apoptosis in HCC HepG2 xenografts. The 18F-FDG micro-PET/CT may be a useful functional imaging modality to assess early response to 125I-IBT in HCC HepG2 xenograft.

Abstract
Background Advanced non-small-cell lung cancer (NSCLC) is a huge challenge for physicians. Traditional chemoradiotherapy is associated with high rates of toxicities, especially when treating gerontal patients. Our study was focused on investigating the safety and efficacy of permanent iodine-125 seed implantation and chemotherapy for the treatment of advanced NSCLC in the elderly. Methods Fifty elderly patients with stage III or IV NSCLC at our hospital from January 2011 to June 2017 were treated with the chemotherapy regimens (paclitaxel/cisplatin) and computed tomography (CT)-guided iodine-125 brachytherapy (group A), 50 patients who received chemotherapy consisting of paclitaxel and cisplatin only (group B) were matched-up with the patients in group A. The local response rate was evaluated by CT. Progression-free survival (PFS) and overall survival (OS) data were obtained through clinical follow-up. Results The patients were followed-up for 3-46 months. With a median follow-up time of 20 months, the OS and PFS were 20 months (95% CI: 19.09-20.90 months) vs 15 months (95% CI: 14.48-15.51 months) (P<0.05) and 13 months (95% CI: 11.96-14.04 months) vs 8 months (95% CI: 7.63-8.37 months) (P<0.05) in group A and group B, respectively. The symptoms of patients in group A were significantly relieved when compared with group B. Severe complications were not observed in either of the groups. Conclusion The combination of iodine-125 seed brachytherapy and chemotherapy is an effective and safe therapy and is superior to chemotherapy alone for advanced NSCLC in the elderly.

Abstract
Iodine-125 interstitial brachytherapy (125I-IBT) is an alternative and effective treatment option for unresectable non-small cell lung cancer (NSCLC), and the Warburg effect is a determinant of tumor growth. The present study aimed to explore the influence of 125I-IBT on tumor growth and the Warburg effect, and the potential mechanisms underlying NSCLC progression. Mice with A549 cell xenografts were evenly divided into a control group without 125I-IBT, and three treatment groups receiving 125I-IBT with 20, 40 and 60 Gy. Tumor volume (TV), maximum standardized uptake value (SUVmax) determined by 18F-fluorodeoxyglucose (18F-FDG) micro-positron emission tomography/computed tomography and mean optical density (MOD) of mammalian target of rapamycin (mTOR), c-Myc, hypoxia inducible factor-1α (HIF-1α) and glucose transporter 1 (GLUT1) staining were compared among groups. Tumor inhibition rate (TIR), 18F-FDG uptake attenuation rate (FUAR) and expression suppression rate (ESR) were also calculated on day 14 and 28. The results demonstrated that the mean TV in the 60 and 40 Gy groups was smaller compared with the control TVs since days 14 and 16, respectively. The mean SUVmax value of the 60 Gy group at day 14, and all treatment group SUVmax values at day 28 were lower compared with the controls. In addition, the MOD of mTOR and GLUT1 was lower in the 60 Gy group, compared with the other groups, and c-Myc and HIF-1α values were lower in the 40 and 60 Gy groups, compared with the control and 20 Gy group (P<0.05). SUVmax positively correlated to TV (day 14, r=0.711; day 28, r=0.586) and the MOD of c-Myc and GLUT1 (r=0.621 and 0.546, respectively; P<0.01). Furthermore, dose dependent increases were observed for TIR, FUAR and ESR. In conclusion, 125I-IBT reduced tumor growth by inhibiting the Warburg effect, which may have resulted from downregulation of mTOR, c-Myc, HIF-1α and GLUT1 expression, particularly c-Myc and GLUT1, in NSCLC A549 ×enografts.

Abstract
Radioactive 125I seed implantation as a means of radiotherapy for malignant tumors has been proved to be safe and effective. Although the effectiveness of 125I seed implantation in the treatment of tumor metastases has been widely recognized, there is still no standard for the selection of radiation doses. Adrenal blood supply is abundant, and it is a common metastatic site for malignant tumors. CT-guided radioactive 125I seed implantation is effective in treating adrenal metastases. However, it may cause certain damage to surrounding organs, especially the stomach. Clinically, for patients with left adrenal metastatic carcinoma and concurrent radioactive seed implantation, the occurrence of permeable gastric ulcer should not be neglected. In order to reduce the effect of radioactive particles on the normal tissue structure around the tumor, low-activity particles should be used.

Abstract
PURPOSE To compare the therapeutic effects of 125I versus non-125I combined with transcatheter arterial chemoembolization (TACE) for the treatment of unresectable hepatocellular carcinoma (HCC) with obstructive jaundice. METHODS A retrospective analysis was conducted using the records of 54 consecutive patients who were initially diagnosed with HCC with obstructive jaundice between May 2009 and July 2016. Twenty-one cases (group A) were treated with percutaneous transhepatic biliary drainage (PTBD) followed by 125I radioactive seed strip implantation through the PTBD tube. After the total serum bilirubin level was reduced to normal and the liver function recovered to Child-Pugh class A or early B, TACE was conducted. In 33 cases (group B) PTBD was performed in combination with TACE without applying the 125I radioactive seeds. The duration of biliary patency and survival were analyzed. RESULTS The technical success rate in both groups was 100%. The median biliary patency time was 6.000 ± 0.315 months (95% CI 5.382-6.618 months) in group A and 4.000 ± 0.572 months (95% CI 2.879-5.121 months) in group B; the two groups were significantly different (P = 0.001). The median survival was 11.000 ± 0.864 months (95% CI 9.306-12.694 months) in group A and 9.000 ± 0.528 months (95% CI 7.965-10.035 months) in group B; the two groups were significantly different (P = 0.022). CONCLUSIONS The combination of 125I with TACE was more effective than TACE without the radioactive seeds for treating patients with unresectable HCC with obstructive jaundice. Future prospective trials with larger samples will be required to validate these results.

Abstract
Recurrent breast cancer remains an incurable malignancy and cannot be removed by surgery in the majority of cases. This study aimed to explore the feasibility and efficacy of the combination of I brachytherapy and chemotherapy for the treatment of unresectable recurrent breast cancer. Patients with unresectable recurrent breast cancer treated between January 2011 and December 2014 with a combination of I brachytherapy and capecitabine or gemcitabine were evaluated and outcomes were compared with those of women treated with capecitabine or gemcitabine in conventional dose as a monotherapy. Of 61 patients evaluated, 28 received the combination treatment and 33 received capecitabine or gemcitabine monotherapy. The combination of I brachytherapy and chemotherapy resulted in a significant improvement in progression-free survival versus capecitabine or gemcitabine monotherapy (median, 17.8 vs 11.4 months; hazard ratio [HR], 0.44; 95% confidence interval [CI], 0.23-0.84; P = 0.013). The objective response rate (ORR) was significantly higher with the combination (82.1%) than with monotherapy (54.5%; P = 0.022), and the rate of pain relief was higher in the combination arm (100% vs 73.6%; P = 0.038). There was no significant improvement for overall survival (median, 30.1 vs 27.2 months; HR, 0.82; 95% CI, 0.47-1.44; P = 0.496). There were no serious complications detected during the follow-up period, any grade toxicities were comparable between treatment arms. In conclusion, the combination of I brachytherapy and second-line chemotherapy is superior to chemotherapy alone and is an effective and safe therapy for unresectable recurrent breast cancer. However, further investigation and much larger scale randomized controlled trials with long-term follow-up are needed.
