Purpose: The objectives of the present study were to evaluate the feasibility, safety, and efficacy of endoscopic ultrasound (EUS)-guided iodine-125 (I) seed implantation in ampullary carcinoma (AC).
Material And Methods: From January 2011 to June 2020, 13 patients were selected for this retrospective study. Thirteen tumors (27.46 ±12.07 mm) were treated with EUS-guided I seed implantation in 29 sessions. We evaluated the therapeutic efficacy, adverse effects, and overall survival (OS) time.
Results: Complete response (CR) was observed in one tumor in 6 months. Partial response (PR) was detected in two target tumors in 3 months, seven in 6 months, seven in 9 months, and six in 12 months. Good periods of survival were observed. The median OS was 35 months, 95% confidence interval (95% CI) was 8.97 to 61.03 months. The 1-, 2-, and 5-year OS rates were 100%, 67.5%, and 11.3%, respectively. There were no procedure-related deaths or serious adverse events. Transient abdominal pain (5 cases, 17.2%), abdominal distension and loss of appetite (3 cases, 10.3%), and seed migration (1 case, 3.4%) were observed, respectively.
Conclusions: In selected patients with inoperable AC, EUS-guided I seed implantation is feasible and safe with favorable local control efficacy and OS.

Objective: The objective of this study was to evaluate the efficacy and safety of TACE combined with 125I seeds (TACE-125I) in the treatment of recurrent HCC at complex sites after hepatectomy.
Methods: This study retrospectively analyzed the clinical data of recurrent HCC patients located at complex sites (such as large blood vessels, diaphragm dome, etc.) after hepatectomy from January 2012 to December 2023, all of whom received TACE-125I or TACE therapy.

Objectives: Mixed reality (MixR) is an innovative visualization tool that presents virtual elements in a real-world environment, enabling real-time interaction between the user and the combined digital/physical reality. We aimed to explore the feasibility of MixR in enhancing preoperative planning and intraoperative guidance for the correction of various complex congenital heart defects (CHDs).
Methods: Patients underwent cardiac computed tomography or cardiac magnetic resonance and segmentation of digital imaging and communications in medicine (DICOM) images was performed.

This report presents the case of a 68-year-old female patient with hepatocellular carcinoma (HCC) who experienced persistently elevated alpha-fetoprotein (AFP) levels following resection of the primary liver tumor. The patient had previously undergone transcatheter arterial chemoembolization (TACE) and liver tumor resection, but postoperative AFP levels continued to rise, suggesting the possibility of extrahepatic metastasis. PET-CT scans revealed an irregular soft tissue mass in the recto-uterine pouch, which was later confirmed as a HCC metastasis through needle biopsy.

Rationale: We report here a case of using iodine-125 (125I) seed implantation via endobronchial ultrasound (EBUS) in the treatment of malignant central airway obstruction (MCAO) in a patient with lung adenocarcinoma.
Patient Concerns: The patient still experienced MCAO after conventional bronchoscopic interventional therapy.
Diagnoses: The patient was diagnosed as lung adenocarcinoma stage IV (T4N2M1a).

Purpose: To compare the effectiveness and safety of CT-guided iodine-125 seed brachytherapy in conjunction with chemotherapy against chemotherapy alone for the management of intermediate and advanced non-small cell lung cancer (NSCLC) lacking oncogenic driving genes.
Methods And Materials: Retrospective analysis was conducted on clinical data from 128 patients diagnosed with intermediate and advanced non-small cell lung cancer who received iodine-125 combined with chemotherapy or chemotherapy alone due to the absence of oncogenic driver gene mutations. The patients in two groups were compared at 6-month follow-up for objective remission rate (ORR), Disease control rate (DCR), local progression-free survival (LPFS), overall survival (OS), clinical symptom improvement, and adverse events.
