To investigate the clinical efficacy and prognostic factors of 125I seeds implantation in the treatment of patients with advanced lung cancer after radiotherapy and chemotherapy. From January 2017 to December 2019, 44 patients (39 males, 5 females, age 41-84 years) with advanced lung cancer after radiotherapy and chemotherapy who received 125I seeds implantation in Hebei General Hospital were retrospectively analyzed. All patients were followed up for ≥12 months, and the clinical efficacies were observed. (Source: Brachytherapy)

There is no one-size-fits-all treatment decision for non-melanoma skin cancer (NMSC) in elderly patients, especially patients over 80 years old with multiple comorbidities. As a minimally invasive technology, iodine-125 seeds interstitial brachytherapy (BT) has been applied to solid tumors of the whole body, because it can offer a better dose distribution, which considered to be an effective, simple and safe alternative for local treatment of cancer. We aimed to explore its safety and efficacy for age 80 or older patient with early primary high-risk NMSC. (Source: Brachytherapy)

An optimized DIxon VIBE MR sequence has previously shown the potential to simultaneously visualize human skin and surface brachytherapy applicators on healthy volunteers. This sequence acquires in-phase (IP) and opposed-phase (OP) images from which water and fat images are automatically reconstructed. OP images provide the highest image contrast for detecting silicon beads of Freiburg Flap applicators and deducing the positions of enclosed catheters. Applicator beads may present chemical shift induced spatial distortions on the original IP and OP acquisitions, which can be mitigated by building their geometric mean. (Source: Brachytherapy)

Perioperative accelerated partial breast irradiation with multicatheter interstitial brachytherapy is an alternative to the postoperative option that offers advantages in terms of specificity and comfort for patients as it avoids a second procedure. Since the simulation CT scan is performed 48 hours after the intervention, immediate tissue changes as air gaps can occasionally be observed. To our knowledge, there is no literature published on this regard, so the aim of this study was to assess the impact of significant air gaps when planning and treating multicatheter perioperative breast cancer brachytherapy.

Non-melanoma skin cancer is the most common cancer worldwide and its treatment in the elderly can pose significant challenges. We established a skin brachytherapy program primarily to treat older patients using the hypofractionated courses and superficial treatment depth afforded by this technique. Here we describe the first patients treated at our institution, including our initial oncologic results and toxicities. (Source: Brachytherapy)

Methods 11 lesions in 8 cases of advanced unresectable differentiated thyroid cancer undergone 125I seeds implantnation with the B ultrasound and CT guided were analysised retrospectively. The activity of 125I seeds ranged from 0.5mCi-0.7mCi.The D90(The dose received by 90% of target volume)of the tumor ranged from 74.6 to 138.8Gy shown by post plan. (Source: Brachytherapy)

Surgery and radiation therapy are standard treatments for lip cancer. Surgery includes removal of all cancer-related tissue and facial reconstruction (cosmetic and functional) of the lips. Reconstruction procedures are available but give a less satisfactory cosmetic result than brachytherapy. In addition, the use of high-dose-rate brachytherapy (HDR-BT) is now becoming more popular than low-dose-rate (LDR) and pulsed-dose-rate (PDR) BT in the treatment of lip cancer since HDR-BT offers the advantage of optimizing dose distribution by varying dwell times.

Invasive lobular carcinoma (ILC) is the second most common breast cancer histology, classically defined by its “single file” appearance and multifocal presentation. Historically this cohort of patients has been considered cautionary for accelerated partial breast irradiation (APBI), given concern for increased risks of recurrence and under-representation on randomized controlled trials.

In Japan, cylindrical excisions are commonly performed in partial mastectomies for breast-conserving therapy, as opposed to the typical lumpectomies. Hence, when implementing Accelerated Partial Breast Irradiation (APBI) with the use of SAVI, a multi-lumen single catheter for partial breast irradiation with brachytherapy, discrepancies were noted between the shape of the excision cavity and the SAVI. Our institution reexamined the correlation between the form of the excision cavity and the shape of SAVI in instances of APBI that utilized post-operative SAVI insertion. (Source: Brachytherapy)

Worldwide, non-melanoma skin cancer (NMSC) has a high incidence. In 2020, Colombia, a Latin American country, had a NMSC incidence of 7.9 per 100.000 inhabitants. High Dose Rate (HDR) skin brachytherapy is a validated treatment option, with optimal and promising local control rates and cosmetic results, equivalent to surgical management and external radiation therapy. Nevertheless, this treatment technique may be scarce in Low Middle-Income Countries (LMICs), due to personnel training and technology requirements. (Source: Brachytherapy)
