Prospective Registry Trial of Adjuvant High-Dose Rate Brachytherapy in Unirradiated Head and Neck Cancer: 20-Year Data.

Background And Purpose: Full-dose postoperative external beam radiation therapy (EBRT)/chemoradiation is the standard of care in patients with resected, unirradiated head and neck cancer (HNC). This study aims to determine the long-term results of adjuvant high-dose rate (HDR) brachytherapy ± intermediate-dose postoperative external beam radiation therapy (EBRT)/chemoradiation in this HNC patient population.

Materials And Methods: From 2000 to 2018, a total of 152 patients diagnosed with HNC were treated with surgery and adjuvant HDR brachytherapy alone (n = 32) or combined with EBRT ± chemotherapy (n = 120).

Reirradiation Practice in Gynecological Cancer: Insights from a National Survey in Spain.

Purpose: Given the lack of standardisation in gynecological cancer reirradiation, the Gyneacologial Radiation Oncology (GINECOR) working group on behalf of the Spanish Society of Radiation Oncology (SEOR), works towards to inquire the current state of reirradiation practices among the radiation oncology departments in Spain.

Methods: An online 37-question survey was sent to all GINECOR members, representing most Spanish centers. The survey addressed general aspects of reirradiation, including experience, reirradiation sites, and techniques used.

Post- versus intra-operative implant for breast cancer interstitial brachytherapy: How to choose?

Purpose: Breast brachytherapy (BB) represents an important radiation therapy modality in modern breast cancer treatments. Currently, BB is mainly used for accelerated partial breast irradiation (APBI), local boost after whole breast radiation therapy (WBRT), and as salvage re-irradiation after second lumpectomy (APBrl). Two multi-catheter interstitial brachytherapy (MIB) techniques can be offered: intra-operative (IOB) and post-operative (POB) brachytherapy.

Very accelerated partial breast irradiation in 1 or 2 days: Late toxicity and early oncological outcome of the GEC-ESTRO VAPBI cohort.

Purpose: To analyze late toxicity after very accelerated partial breast irradiation (VAPBI) for low-risk breast cancer.

Materials: Methods: In this retrospective, observational, international multicenter study (HDH F20220713143949), patients with low-risk breast cancer underwent lumpectomy + vAPBI (high-dose rate multicatheter interstitial brachytherapy-MIBT). VAPBI was performed with 4(4x6.

Long-term results of intraoperative multicatheter breast implant (IOMBI) for accelerated partial breast irradiation (APBI) on early breast cancer patients.

Background And Purpose: Multicatheter breast brachytherapy is a standard technique for accelerated partial breast irradiation (APBI) in early breast cancer patients. Intraoperative multicatheter breast implant (IOMBI) followed by perioperative high-dose-rate brachytherapy (PHDRBT) offers a novel and advantageous approach. We present long-term oncological, toxicity, and cosmesis outcomes for a well-experienced single institution.

Four-fraction ultra-accelerated minimal breast irradiation in early breast cancer: The initial feasibility results of an institutional experience.

Purpose: To evaluate the feasibility, early toxicity, and clinical outcomes of early-breast cancer patients in a single-arm, phase I/II study of an ultra-accelerated, four-fraction schedule of minimal breast irradiation (4f-AMBI) using a multicatheter, minimally-invasive, intraoperative tumor bed implant (MITBI) during breast-conserving surgery (BCS).

Methods And Materials: Eligible women aged >40 years with clinically and radiologically confirmed, unifocal invasive or in situ ≤3 cm tumors were considered as potential candidates for MITBI during BCS. After the pathology report, patients who met APBI criteria received ultra-accelerated four-fractions irradiation (6.

Minimally invasive tumor bed implant (MITBI) and peri-operative high-dose-rate brachytherapy (PHDRBT) for accelerated minimal breast irradiation (AMBI) or anticipated boost (A-PHDRBT-boost) in breast-conserving surgery for ductal carcinoma in situ.

Purpose: To evaluate our institutional experience of minimally invasive tumor bed implantation (MITBI) during breast-conserving surgery (BCS) for ductal carcinoma (DCIS) to deliver peri-operative high-dose-rate brachytherapy (PHDRBT) as accelerated minimal breast irradiation (AMBI) or anticipated boost (A-PHDRBT-boost).

Material And Methods: Patients older than 40, with clinical and radiological unifocal DCIS < 3 cm were considered potential candidates for accelerated partial breast irradiation (APBI) and were implanted during BCS using MITBI-technique. Patients who in final pathology reports showed free margins and no other microscopic tumor foci, received AMBI with PHDRBT (3.

Dose volume histogram constraints in patients with head and neck cancer treated with surgery and adjuvant HDR brachytherapy: A proposal of the head and neck and skin GEC ESTRO Working group.

Background: The Head and Neck and Skin (HNS) Working group of the GEC-ESTRO acknowledges the lack of widely accepted Dose Volume Histogram (DVH) constraints in adjuvant head and neck brachytherapy and issues recommendations to minimize mandibular Osteoradionecrosis (ORN) and Soft Tissue Necrosis (STN).

Methods: A total of 227 patients with the diagnosis of head and neck cancer treated with surgery and adjuvant HDR brachytherapy alone or combined with other treatment modalities during the period 2000-2018 were analyzed.

Results: STN was observed in 28 out of 227 cases (12.
