Background CalliSpheres® beads (CB) have been used recently for patients with hepatocellular carcinoma. However, the safety and effect of drug-eluting bead transarterial chemoembolization (DEB-TACE) in patients with stage III–IV lung cancer are still unknown. Purpose To evaluate the safety and efficacy of DEB-TACE with pirarubicin-loaded CB for the treatment of stage III–IV lung cancer. Material and Methods From July 2016 to April 2020, 29 patients with stage III–IV primary lung cancer underwent DEB-TACE with pirarubicin-loaded CB. The objective response rate (ORR) was the primary endpoint; the secondary endpoints were progression-free survival (PFS) and overall survival (OS). Results Twenty-nine patients received DEB-TACE with pirarubicin-loaded (median 60 mg) CB, with no severe adverse events or treatment-related deaths. After DEB-TACE, hemoptysis disappeared within 1–3 days in all patients, and the symptoms of cough or expectoration were significantly improved in 12 patients. ORR and disease control rate at one, three, and six months after DEB-TACE were 39.3% and 96.4%, 26.1% and 69.6%, and 29.4% and 58.8%, respectively. The median PFS was 6.3 months (range 1.1–30.1 months), and the three-, six-, and 12-month PFS rates were 70.2%, 50.1%, and 27.1%, respectively. The median OS was 10.2 months (range 1.1–44.6 months), and the three-, six, and 12-month OS rates were 87.9%, 68.6%, and 39.8%, respectively. Conclusion DEB-TACE with pirarubicin-loaded CB is safe, feasible, and well-tolerated for patients with stage III–IV lung cancer, and symptom control was a potential benefit of treatment.

Background The clinical outcomes of drug-eluting beads transarterial chemoembolization (DEB-TACE) with doxorubicin-loaded CalliSpheres® beads for patients with unresectable or recurrent esophageal carcinoma have not been reported. The aim of this study is to study the clinical outcomes of DEB-TACE for patients with unresectable or recurrent esophageal carcinoma. Methods This retrospective study enrolled 21 patients (15 men; mean age 68.7 ± 9.7; range 46–86 years) with unresectable or recurrent esophageal carcinoma received DEB-TACE between July 2017 and September 2020. Patient characteristic data, imaging findings, complications and DEB-TACE procedure were reviewed. The primary endpoints, disease control rate (DCR) and objective response rate (ORR), were calculated. The secondary endpoints were overall survival rate and progression-free survival (PFS). Results Twenty-two sessions of DEB-TACE were performed in 21 patients. The technical success rate was 100%; without sever adverse events or procedure-related deaths. All patients received transarterial chemotherapy infusion with raltitrexed or oxaliplatin. The median follow-up period was 3.6 months (interquartile range, IQR 1.5–9.4 months). ORR and DCR were 42.9 and 85.7%, 28.6 and 71.4%, 20.0 and 40.0% respectively at 1-, 3-, and 6-months after DEB-TACE. The median PFS was 6.0 months, and the 3-, 6- and 12-month PFS rates were 68.2%, 45.5 and 0.0%, respectively. The median overall survival was 9.4 months, and the 3-, 6- and 12-month overall survival rates were 75.5%, 55.0 and 13.8%, respectively. Conclusions To our knowledge, this is the first study reports outcomes of DEB-TACE with doxorubicin-loaded CallSpheres bead treatment in the management of patients with unresectable or recurrent esophageal carcinoma. According to our results, this is a safe and feasible treatment modality that may be considered among the options for the treatment of these patients.

Self-expandable metallic stents (SEMSs) have been widely used in the treatment of malignant central airway obstruction. However, few reports focus on the treatment of atelectasis and how to estimate the prior probability of success via SEMSs placement, This current study aimed to study the safety and effectiveness of SEMSs for the treatment of obstructive atelectasis, and the value of preoperative CT enhancement for ventilation of atelectasis via SEMSs placement. A total of 35 patients with obstructive atelectasis (29 male and 6 female) was included from February 2012 to March 2018. The procedures were performed under fluoroscopic guidance, and bronchoscopic laser resection was performed for severe restenosis cases after SEMSs placement. Clinical and functional pulmonary data were recorded before and 3 months after the procedure. Follow-up involved clinical data and radiographic techniques at 48 h and at 1-, 3-, 6-, and 12-month intervals. Thirty-eight SEMSs were successfully implanted in 34 patients, included 29 Y type tracheal stents, 4 small y stents, and 5 straight airway stents. After stenting, 26 cases showed full ventilation, and 3 cases were partially ventilated. The technical success and clinical success was 97.1% and 82.9%, respectively. A higher maximum enhancement CT value was found in patients with full ventilation. Mean follow-up time was 18.8 ± 4.0 months. Eight cases showed restenosis and received endoscopic laser resection, included 1 case underwent removal and 3 cases received second stenting. There were 2 cases of perioperative non-operative death, and 11 cases of post-discharge death (2 cardiac deaths and 9 malignant tumors). The survival rates of 3 months, 1 year and 2 years were 78.6%, 58.5% and 58.5%, respectively. In conclusion, SEMSs placement is safe and effective for obstructive atelectasis, and the preoperative CT enhancement played an important role in estimating the prior probability of success in the treatment of atelectasis via SEMSs placement. Obstructive atelectasis caused by malignant lung or esophageal cancer is a clinical emergency, which is characterized by progressive dyspnea and risk of asphyxiation. Patients often show chronic dyspnea and difficulty to receive surgical resection, chemotherapy, and radiotherapy, thereby resulting in low quality of life and poor prognosis 1. Although SEMSs has been widely used for palliation of airway stenosis, especially malignant central airway obstruction 2-8. At present, few reports have described the treatment of atelectasis via SEMSs placement, except for some case reports 1,9-11. SEMSs implantation can relieve symptoms, improve pulmonary function and stabilize cardiovascular conditions to undertake a successful surgical correction 11. However, stent treatment also brings potential fatal complications, such as stent restenosis caused by tumor or granulation tissue, stent fracture, and stent migration 12-14. Hachiya et al. even reported the potential risk of creating obstructive atelectasis in two cases after stenting 2. Thus it is impo...

Objective Thoracic endovascular aortic repair (TEVAR) is considered the mini-invasive treatment of choice for patients with Stanford type B aortic dissection (TBAD). This study aimed to investigate the clinical outcomes and quality of life (QoL) in patients with acute and subacute TBAD after TEVAR. Methods From January 2014 until July 2016, 22 acute patients (Group A) and 18 subacute patients received TEVAR (Group B), and 13 patients were managed non-operatively (Group C). The Medical Outcomes Study Short Form-36 was used to assess QoL preoperatively and after TEVAR. Operative techniques and complications were retrospectively analyzed. Results The role emotion, vitality, and mental health domains scored well preoperatively. Except for role emotion, vitality, and mental health, the remaining domains significantly improved after TEVAR. There was no significant difference in QoL metrics between Groups A and B. In Group C, bodily pain and social functioning domains were improved, and role emotion was decreased, with no improvement in the remaining domains. The 3-year survival rates were 95.5%, 100%, and 85.7% for Groups A, B, and C, respectively. Conclusions TEVAR may be safe and effective in patients with acute and subacute TBAD with similar and favorable clinical and QoL metrics.

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

Background: This study aimed to report long-term outcome of superselective embolization in patients with highflow priapism refractory to medical and surgical treatments. Methods: From August 2011 until July 2016, 14 patients with high-flow priapism refractory to local treatments were treated and their charts were retrospective reviewed. Clinical evaluation, color Doppler ultrasonography, arteriography and selective embolization were performed. Follow up was performed in all patients. Fourteen men (18-63 years old) were enrolled, with priapism duration of 14 h to 28 days. Internal pudendal arteries or glutaea inferior arteriae were successfully embolized with gelatin sponge particles, polyvinyl alcohol particles or microcoils. Results: Pseudoaneurysm in right femoral artery was found in one case after intervention. The follow-up 1 week later showed that 13 patients were in good condition, the priapism diminished 1-7 days (mean 3.2 ± 0.5 days) after intervention, and 1 patient received second intervention. Mean follow-up was (range 10.8-69.6) months. One patient had recurrent priapism months after embolization and had his penis surgically removed for severe necrosis. Conclusions: Superselective embolization is safe and effective in high-flow priapism refractory local treatments, with a good long-term prognosis.
