The overall pelvic control was 89%. The overall recurrence rate was 25% and distant metastases rate was 22%. The overall 5-year survival rate was 65% and cancer-specific survival rate was 69%. Prognostic factors were FIGO stage and total brachytherapy dose (D
) to HRCTV. Late serious toxicity of the bladder and intestine were rare, occurring in only 3% of patients.

The local and pelvic control rates were excellent in this series. The IGABT was an important part of the treatment schedule and could probably not be replaced by increasing the external pelvic dose. Adenocarcinomas seemed to benefit from the addition of interstitial needles. Late serious toxicity was rare.

To record and report dosimetric and clinical outcomes of interstitial brachytherapy using cobalt-60 (
Co) source in cervical cancer.

Seventy patients who underwent external beam radiotherapy with dose of 45 Gy in 25 fractions, followed by interstitial brachytherapy (ISBT) 6.5 Gy × 4 fractions were included into this study. The ISBT applicators were inserted under combined spinal and epidural anesthesia. Computed tomography (CT) simulation was performed and axial CT images were transferred to treatment planning system. High-risk clinical target volume (CTV
) and organs at risks (OARs) were contoured. Four fractions of 6.5 Gy were prescribed to CTV
using inverse planning technique. Patients were followed-up for 3 years. Dosimetric parameters and clinical outcomes were recorded and compared with available literature.

Seventy patients with FIGO stage IIB-IVA were included in the study. The median EQD
of 2 cm
of bladder, rectum, sigmoid and D
CTV
were 70 Gy (53-75 Gy), 64 Gy (51-71 Gy), 48 Gy (44 similar, compared to available literature using iridium-192 (192Ir) source.
To evaluate the safety and efficacy of computed tomography (CT)-guided
I radioactive seed implantation in patients with malignant airway compression induced by advanced lung cancer.

Between June 2015 and June 2018, 40 patients from three medical institutions with malignant airway compression induced by advanced lung cancer were treated with
I seed implantation. The outcomes were measured in technical success and safety, objective response rate, complications, Karnofsky performance status (KPS) score, and survival time.

All 40 patients successfully underwent implantation procedure. No procedure-associated death occurred. The most common complications were irritable cough, temporary hemoptysis, chest pain, fever, and pneumothorax, which occurred in 26 (65.0%), 31 (77.5%), 12 (30.0%), 15 (37.5%), and 11 (27.5%) patients, respectively. The objective response rates were 100%, 100%, 100%, 87.5%, and 83.3% at the 3
, 6
, 12
, 24
, and 36
months post-procedure, respectively. The KPS score significantly improved at post-procedure. Median survival time was 25.1 months. Actuarial survival rates were 100%, 60%, and 15% at the 12
, 24
, and 36
months after the procedure, respectively.

I seed is a safe and effective alternative treatment option.

Small lung metastases change their location with respiration, making difficult to localize, therefore, increasing the number of punctures. Accurate puncture can reduce trauma to lung tissue and accelerate patient's recovery. The aim of the study was to present our experience with the technique of using local anesthesia 5-ml syringe as a guide for computerized tomography-guided iodine-125 seed implantation (CT-ISI).

This was a retrospective study, including patients with small metastatic tumors in the lung, treated with CT-ISI between December 2013 and March 2018 at the Affiliated Hospital of the University. The patients were divided according to whether a 5-ml syringe was used as a guide during CT-ISI or not. The final follow-up was on March 31
, 2018. Implantation success and complications were examined.

Nineteen patients were included. A total of 840 seeds were used, with 44.2 ±33.6 (range, 10-160) seeds per patient. The mean D
for CT-ISI was 134.5 ±7.5 Gy. Treatment intervention for eleven patients was performed using a 5-ml syringe as a guide during CT-ISI. There were no differences in total dose and number of implanted seeds between the two groups, but the number of punctures per lesion was lower in the syringe group than in the no-syringe group (1.9 ±0.5 vs. 2.9 ±0.6,
< 0.001), suggesting a higher puncture accuracy. The total number of SMTIL was 50 (median, 2; range, 1-10), and the median size was 1.9 cm (range, 0.8-2.4 cm). All SMTIL were well-controlled at 6-months follow-up (response rate [RR] = 100%). One patient in the no-syringe group experienced grade 2 chest tightness, chest pain, intraoperative needle tract bleeding, and post-operative blood in sputum.

Puncture with a 5-ml syringe as a guide during CT-ISI seems to be a more accurate option for patients with small (< 2.5 cm) lung metastasis.

To explore the possibility of intraoperative transrectal ultrasound (TRUS)-based dose verification in transperineal brachytherapy (BT) with iodine-125 (
I) seeds for prostate cancer.

Fifteen patients with prostate cancer were treated using BT with
I seeds. https://www.selleckchem.com/products/ABT-888.html Post-implant TRUS and computed tomography (CT) images were imported into treatment planning system (TPS) for dosimetry. Dosimetry parameters, including minimum dose received by 90% of the volume (D
), percentage of the volume receiving 100% of prescribed dose (V
), and percentage of the volume receiving 200% of prescribed dose (V
) were calculated based on TRUS and CT images, separately. The D
value of TRUS-based dosimetry was transformed to its expected value. Comparisons of the dosimetric parameters between post-operative verification and preoperative plans were made by paired
-test. One-way ANOVA model was used to assess the differences in preoperative plans. Agreements were evaluated between the preoperative planning and post-operative actual dose parameters using Bland-Altman analysis.
