Abstract
Activated guided irradiation by X-ray (AGuIX) nanoparticles are gadolinium-based agents that have the dual benefit of mimicking the effects of a magnetic resonance imaging (MRI) contrast agent used in a clinical routine and enhancing the radiotherapeutic activity of conventional X-rays (for cancer treatment). This "theragnostic" action is explained on the one hand by the paramagnetic properties of gadolinium and on the other hand by the generation of high densities of secondary radiation following the interaction of ionizing radiation and high-Z atoms, which leads to enhanced radiation dose deposits within the tumors where the nanoparticles accumulate. Here, we report the results of a phase I trial that aimed to assess the safety and determine the optimal dose of AGuIX nanoparticles in combination with chemoradiation and brachytherapy in patients with locally advanced cervical cancer. AGuIX nanoparticles were administered intravenously and appropriately accumulated within tumors on a dose-dependent manner, as assessed by T1-weighted MRI, with a rapid urinary clearance of uncaught nanoparticles. We show that the observed tumor accumulation of the compounds can support precise delineation of functional target volumes at the time of brachytherapy based on gadolinium enhancement. AGuIX nanoparticles combined with chemoradiation appeared well tolerated among the 12 patients treated, with no dose-limiting toxicity observed. Treatment yielded excellent local control, with all patients achieving complete remission of the primary tumor. One patient had a distant tumor recurrence. These results demonstrate the clinical feasibility of using theranostic nanoparticles to augment the accuracy of MRI-based treatments while focally enhancing the radiation activity in tumors.

Dose Contribution to the Regional Lymph-Node Metastases and Point B from Intracavity and Interstitial Hybrid Brachytherapy in Locally Advanced Cervical Cancer. Cancers (Basel) 2024; 16:2384. [PMID: 39001446 PMCID: PMC11240443 DOI: 10.3390/cancers16132384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 07/16/2024] Open
Abstract
PURPOSE Analyzing dose distributions to regional lymph-node metastases (RLNMs) in locally advanced cervical cancer (LACC) patients undergoing intracavitary and interstitial hybrid brachytherapy (IC/IS). METHODS Dose distributions of eleven LACC patients with 38 RLNMs, and who received 38 IC/IS sessions were analyzed in EQD2, considering RLNM positions and ipsilateral interstitial needles; these RLNMs, excepting the para-aortic region, were classified into four groups. RESULTS RLNMs had a median of two ipsilateral interstitial needles per session. Significant differences were observed in total RLNM D90, depending on whether the position was cranial or caudal of the uterine base (85.5 vs. 378.9 cGy, p < 0.0001), and whether the RLNM D90 was associated with a number of ipsilateral interstitial needles between 0-1 or 2 or more (68.4 vs. 112.2 cGy, p = 0.006) per session. At each session, Group 1 RLNMs (cranial of the uterine base, 0-1 ipsilateral interstitial needle) had a mean D90 of 21.1 cGy; Group 2 (cranial, 2 or more), 73.8; Group 3 (caudal, 0-1), 94.7; and Group 4 (caudal, 2 or more), 136.1. CONCLUSION RLNMs located caudal of the uterine base associated with two or more ipsilateral interstitial needles in IC/IS had a higher dose contribution, which should be considered when calculating the RLNMs' dose of external beam boost irradiation.

Abstract
PURPOSE To assess experiences of sexuality and of receiving sexual healthcare in cervical cancer (CC) survivors. METHODS A qualitative phenomenological study using semistructured one-on-one interviews was conducted with 15 Belgian CC survivors recruited in 5 hospitals from August 2021 to February 2022. The interviews were audiotaped and transcribed verbatim. Data were analyzed using inductive thematic analysis. COREQ and SRQR reporting guidelines were applied. RESULTS Most participants experienced an altered sexuality after CC treatment with often long-term loss/lack of sex drive, little/no spontaneity, limitation of positions to avoid dyspareunia, less intense orgasms, or no sexual activity at all. In some cases, emotional intimacy became more prominent. Physical (vaginal bleeding, vaginal dryness, dyspareunia, menopausal symptoms) and psychological consequences (guilt, changed self-image) were at the root of the altered sexuality. Treatment-induced menopause reduced sex drive. In premenopausal patients, treatment and/or treatment-induced menopause resulted in the sudden elimination of family planning. Most participants highlighted the need to discuss their altered sexual experience with their partner to grow together toward a new interpretation of sexuality. To facilitate this discussion, most of the participants emphasized the need for greater partner involvement by healthcare providers (HPs). The oncology nurse or sexologist was the preferred HP with whom to discuss sexual health. The preferred timing for information about the sexual consequences of treatment was at treatment completion or during early follow-up. CONCLUSION Both treatment-induced physical and psychological experiences were prominent and altered sexuality. Overall, there was a need for HPs to adopt proactive patient-tailored approaches to discuss sexual health.

Abstract
Multiple sclerosis (MS) as a chronic, degenerative autoimmune disease of the central nervous system has a longitudinal and heterogeneous course with increasing treatment options and risk profiles requiring constant monitoring of a growing number of parameters. Despite treatment guidelines, there is a lack of strategic and individualised monitoring pathways, including respective quality indicators (QIs). To address this, we systematically developed transparent, traceable, and measurable QIs for MS monitoring. Through literature review, expert discussions, and consensus-building, existing QIs were identified and refined. In a two-stage online Delphi process involving MS specialists (on average 53 years old and with 25 years of professional experience), the QIs were evaluated for content, clarity, and intelligibility, resulting in a set of 24 QIs and checklists to assess the quality of care. The final QIs provide a structured approach to document, monitor, and enhance the quality of care for people with MS across their treatment journey.

Abstract
Background and purpose Image-guided adapted brachytherapy (IGABT) is superior to other radiotherapy techniques in the treatment of locally advanced cervical cancer (LACC). We aimed to investigate the benefit of interstitial needles (IN) for a combined intracavitary/interstitial (IC/IS) approach using IGABT over the intracavitary approach (IC) alone in patients with LACC after concomitant external beam radiotherapy (EBRT) and chemotherapy. Materials and methods We included consecutive patients with LACC who were treated with IC/IS IGABT after radiochemotherapy (RCT) in our retrospective, observational study. Dosimetric gain and sparing of organs at risk (OAR) were investigated by comparing the IC/IS IGABT plan with a simulated plan without needle use (IC IGABT plan) and the impact of other clinical factors on the benefit of IC/IS IGABT. Results Ninety-nine patients were analyzed, with a mean EBRT dose of 45.5 ± 1.7 Gy; 97 patients received concurrent chemotherapy. A significant increase in median D90% High Risk Clinical target volume (HR-CTV) was found for IC/IS (82.8 Gy) vs IC (76.2 Gy) (p < 10-4). A significant decrease of the delivered dose for all OAR was found for IC/IS vs IC for median D2cc to the bladder (77.2 Gy), rectum (68 Gy), sigmoid (53.2 Gy), and small bowel (47 Gy) (all p < 10-4). Conclusion HR-CTV coverage was higher with IC/IS IGABT than with IC IGABT, with lower doses to the OAR in patients managed for LACC after RCT. Interstitial brachytherapy in the management of LACC after radiotherapy provides better coverage of the target volumes, this could contribute to better local control and improved survival of patients.

Abstract
PURPOSE This study surveyed radiation oncologists in Morocco to explore current practices and perspectives on brachytherapy for cervix cancer. METHODS AND MATERIALS A 37-question survey was conducted in April 2023 among 165 Moroccan radiation oncologists using Google Forms. RESULTS Of the 93 respondents, 39% treated over 20 patients in 2022 using 3D image-guided brachytherapy (BT) through the HDR technique; 2D techniques were not reported in the last five years. Intracavitary BT is uniformly applied with a tandem and ovoid applicator. Only 14% utilized interstitial needles for hybrid BT. Iridium-192 was the primary radioactive source (63%), followed by cobalt (37%). Ultrasound-guided 47% of applicator insertions. All used CT scans for planning, but only 6% used MRI fusion due to limited availability. Guidelines for target volume and dose prescription were mostly based on GEC-ESTRO recommendations (74%), followed by Manchester Point A (30.4%) and ABS (11%). Over 90% delineated CTV-HR and CTV-IR; 30% delineated GTV. All marked the bladder and rectum, while 52% marked the sigmoid, 5% the small bowel, and 3% the recto-vaginal point. For dosimetry, 12% used ICRU 89 points, 54% used dose-volume histograms (DVH), and 36% used both. Most reported EQD2cc for OARs for the rectum and bladder, with nine still using ICRU point doses. The most common fractionation schema was 7 Gy in four fractions (60%) and 7 Gy in three fractions (55%). CONCLUSIONS Brachytherapy remains essential for treating cervical cancer in Morocco. Key areas for improvement include MRI fusion-guided brachytherapy, access to advanced applicators, expanding interstitial techniques, and professional training and national referential.

Abstract
The quality of cancer care in the modern era is based on a precise diagnosis and personalized therapy according to patients and their disease based on validated guidelines with a high level of evidence. During cancer patients' management, the objective is first to make an accurate diagnosis and then offer the best treatment, validated beforehand in a multidisciplinary board meeting, with the best benefit/risk ratio. In the context of many low- and middle-income countries, the limited available means do not allow an adequate offer, resulting in non-optimal patients' care. In addition, in many low- and middle-income countries, priority can be given to other types of disease than cancer, which may considerably reduce allocation of specific resources to cancer care. Thus, the limited availability of systemic therapy, radiotherapy machines, brachytherapy and technological development may come up against another difficulty, that of geographical distribution of the means in the countries or a lack of expertise due to insufficient training programs. For all these reasons, the implementation of the guidelines established in Western countries could be impossible for many low- and middle-income countries which, moreover, have to face a completely different epidemiology of cancers compared to developed countries. In this work, we will discuss through a few examples of common cancers on both borders of the Mediterranean area, the applicability of the guidelines and the limits of their implementation for optimal cancer care.
