The impact of fractionation on secondary malignancies in postoperative breast cancer irradiation.

PURPOSE: Randomized studies demonstrated the oncological equivalence of (ultra-)hypofractionation compared to a 5-week schedule in postoperative radiotherapy of breast cancer. Due to the low incidence and long latency of secondary malignancies, there are currently no reliable clinical data regarding the influence of fractionation regimens on the development of secondary malignancies. MATERIAL AND METHODS: For 20 patients with right or left-sided breast cancer, postoperative treatment plans were created using 3D-CRT (n = 10) or VMAT (n = 10) for three different fractionation schedules: 5-week schedule with 50.4Gy in 1.8Gy (28fx), hypofractionation with 40.05Gy in 2.67Gy (15fx) and ultra-hypofractionation with 26Gy in 5.2Gy (5fx). The EARs (absolute additional cases of disease per 10,000 patient-years) for secondary malignancies in the lung, contralateral breast, esophagus, liver, thyroid, spinal cord, bones and soft tissue were calculated using a fraction-dependent dose-response model. RESULTS: Based on risk modulation, (ultra-)hypofractionation resulted in significantly lower EARs for lung cancer (LC), contralateral breast cancer (CBC) and soft tissue sarcoma (STS) (p < .001). For the ultra-hypofractionated dose concept the median EARs for LC, CBC and STS were 42.8 %, 39.4 % and 58.1 % lower compared to conventional fractionation and 31.2 %, 25.7 % and 20.3 % compared to hypofractionation. The influence of fractionation on the risk of secondary malignancies for LC and CBC was less pronounced with 3D-CRT than with VMAT. For STS, however, the influence of fractionation was greater with 3D-CRT than with VMAT. CONCLUSION: Based on this simulation study (ultra-)hypofractionated postoperative breast cancer irradiation may be associated with a lower risk of secondary malignancies compared to a 5-week schedule.

Spatio-temporal distributions of COVID-19 vaccine doses uptake in the Netherlands: a Bayesian ecological modelling analysis.

In the transitioning era towards the COVID-19 endemic, there is still a sizable population that has never been vaccinated against COVID-19 in the Netherlands. This study employs Bayesian spatio-temporal modelling to assess the relative chances of COVID-19 vaccination uptake - first, second, and booster doses - both at the municipal and regional (public health services) levels. Incorporating ecological regression modelling to consider socio-demographic factors, our study unveils a diverse spatio-temporal distribution of vaccination uptake. Notably, the areas located in or around the Dutch main urban area (Randstad) and regions that are more religiously conservative exhibit a below-average likelihood of vaccination. Analysis at the municipal level within public health service regions indicates internal heterogeneity. Additionally, areas with a higher proportion of non-Western migrants consistently show lower chances of vaccination across vaccination dose scenarios. These findings highlight the need for tailored national and local vaccination strategies. Particularly, more regional efforts are essential to address vaccination disparities, especially in regions with elevated proportions of marginalized populations. This insight informs ongoing COVID-19 campaigns, emphasizing the importance of targeted interventions for optimizing health outcomes during the second booster phase, especially in regions with a relatively higher proportion of marginalized populations.

Centromedian thalamic deep brain stimulation for idiopathic generalized epilepsy: Connectivity and target optimization.

There are limited treatment options for individuals with drug-resistant idiopathic generalized epilepsy (IGE). Small, limited case series suggest that centromedian thalamus deep brain stimulation (CM-DBS) may be an effective treatment option. The optimal CM-DBS target for IGE is underexamined. Here, we present a retrospective analysis of CM-DBS targeting and efficacy for five patients with drug-resistant IGE. Volume of tissue activated (VTA) overlap with CM nucleus was performed using an open-source toolbox. Median follow-up time was 13 months. Median convulsive seizure frequency reduction was 66%. One patient had only absence seizures, with >99% reduction in absence seizure frequency. Four patients had electrode contacts positioned within the CM nucleus target, all of whom had >50% reduction in primary semiology seizure, with 85% median seizure reduction (p = .004, paired-sample t test). Volumetric "sweet-spot" mapping revealed that best outcomes were correlated with stimulation of the middle ventral CM nucleus. Connectivity strength between the sweet-spot region and central peri-Rolandic cortex was increased significantly relative to other cortical regions (p = 8.6 × 10-4, Mann-Whitney U test). Our findings indicate that CM-DBS can be an effective treatment for patients with IGE, highlight the importance of accurate targeting and targeting analysis, and within the context of prior work, suggest that ideal CM-DBS targets may be syndrome specific.

An anatomical atlas of Drosophila melanogaster-the wild-type.

Scanning electron microscopy is the method of choice to visualize the surface structures of animals, fungi, plants, or inorganic objects at the highest resolution and often with impressive appeal. Numerous scanning electron microscope (SEM) images exist of Drosophila melanogaster, one of the most important model organisms in genetics and developmental biology, which have been taken partly for esthetics and often to solve scientific questions. Our work presents a collection of images comprising many prominent anatomical details of D. melanogaster in excellent quality to create a research and teaching resource for all Drosophilists.

A Standardized Approach to MRI-Guided Stereotactic Laser Corpus Callosotomy: Technical Description and Pediatric Case Series.

BACKGROUND AND OBJECTIVES: Corpus callosotomy is an effective procedure approach for treating medication-resistant drop seizures, which pose a significant challenge in patients with epilepsy. Laser interstitial thermal therapy offers an alternative to open surgery for performing corpus callosotomy that may limit approach-related comorbidities. Practices vary regarding the number of laser filaments used and staging; outcome data for pediatric patients remain relatively limited. METHODS: We illustrate a set of 4 standardized trajectories for performing MRI-guided stereotactic laser corpus callosotomy (SLCC). For this retrospective cohort study in a pediatric neurosurgery practice, the medical records and imaging were reviewed for 10 consecutive patients who had medication-refractory drop seizures and underwent SLCC. Data collected and analyzed included patient and epilepsy characteristics, procedural details, surgical approaches, and clinical follow-up results. RESULTS: Over 2 years, complete, single-stage SLCC was performed in 8 patients, and posterior completion SLCC was performed in 2 patients who had previously had open anterior corpus callosotomy. Four laser fibers were used in four-eighth complete SLCC, and 3 fibers were used in four-eighth complete SLCC. Seven of 10 patients were discharged from the hospital on postoperative day 1, with only 1 requiring a maximum stay of 6 days. Five of 9 evaluable patients reported no drop seizures at the last clinical follow-up. In the other 4 patients, 1 experienced them only rarely, another experienced less than 25% preoperative frequency, and the remaining 2 had less than a 50% improvement. In addition, improvement in other seizure types exceeded 50% in 8 of 9 patients. Notably, no perioperative or postoperative complications were observed, nor were there any sustained neurological deficits reported. CONCLUSION: Complete SLCC can be safely and effectively performed in pediatric patients. It is comparable in effectiveness with open surgery but has lower complication rates and shorter hospitalization.

Cross-species brain-wide mapping reveals a conserved and coordinated network engaged by NAc DBS.

Nucleus accumbens (NAc) deep brain stimulation (DBS) has been increasingly explored as a treatment modality for refractory neuropsychiatric disorders. Uncovering the accumbens network that is engaged by DBS is a critical step forward in understanding how modulating this important node impacts the broader mesocorticolimbic circuit. Using whole-brain clearing and unbiased, brain-wide neural activity mapping, we found that NAc DBS increases neural activity in a coordinated mesocorticolimbic network in mice. Simultaneous intracranial electrophysiology recordings from the human NAc and brief stimulation epochs of homologous mesocorticolimbic nodes revealed similar connectivity. Altogether, these results identify specific connectivity conserved across species within the mesocorticolimbic circuit that may underlie mechanisms of NAc DBS.

Sex work, syndemic conditions and condomless anal intercourse among men who have sex with men who engage in sex work in Latin America.

Background In Latin American countries and Suriname, sexual transmission is one of the most common modes of HIV transmission, and men who have sex with men (MSM) who engage in sex work constitute a key population. Methods In a sample of MSM (N =53,166) from the Latin American Internet Survey (2018) across 18 countries, we examined how sex work engagement is associated with syndemic conditions (multidrug use, homophobic abuse, depression/anxiety, alcohol dependency (CAGE alcohol questionnaire) and internalised homonegativity) and condomless anal intercourse with non-steady male partners using separate logistic regressions. We then used a structural equation model to determine if and how syndemic conditions mediate the relationship between sex work engagement and non-steady male partners. Results We found that getting paid for sex was associated with less condom use for anal intercourse with non-steady male partners and particular syndemic conditions, such as multidrug use, homophobic abuse and alcohol dependency. In our structural equation model, the results showed that the direct relationship between sex work engagement and non-steady male partners was positive and significant, and syndemic conditions partially mediated this relationship. Conclusion Our results highlight the continuing need for including MSM who engage in sex work and those who experience syndemic conditions in the prevention strategies targeted to MSM in Latin America and Suriname, to prevent the transmission of HIV.

Time-efficient consultation hours in the department of gynecological endocrinology.

BACKGROUND: The aim was to conduct a benchmark pilot study to find the best practice for consultation hours in the field of gynecological endocrinology. Suitable benchmarking participants were found in China, Germany, Greece, and Switzerland. Specifically, the study aimed to find the most time-efficient and beneficial consultation type in gynecological endocrinology focused on menopause and whether a shorter face-to-face consultation correlates with lower patient satisfaction. METHODS: This was an observational study. To analyze the processes of all benchmarking participants three tools were used: a measurement of time needed for the different consultation types, a questionnaire for patients and one for physicians. The primary endpoint was the time measurement of first consultations. Secondary endpoints were the time measurements of follow-up consultations and phone consultations and patient satisfaction. RESULTS: The mean overall duration of a first consultation differed from 20.4 min to 39.7 min (p = 0.003), mainly based on differences of the mean time to acquire the patient history, 5.6 to 21.6 min (p < 0.001). The percentage of patients who felt they had enough time to discuss questions ranged from 70% to 100% (p < 0.001). The percentage of patients who felt fully understood by their physician ranged from 62.5% to 92% (p = 0.006). The duration of a first consultation did not correlate with patients feeling well consulted (r=-0.048, p = 0.557). CONCLUSIONS: A concise patient history that concentrates on the most relevant points can reduce the total consultation time. Reducing consultation time can be made without compromising how well patients feel consulted.

MASTER-NAADP: a membrane permeable precursor of the Ca2+ mobilizing second messenger NAADP.

Upon stimulation of membrane receptors, nicotinic acid adenine dinucleotide phosphate (NAADP) is formed as second messenger within seconds and evokes Ca2+ signaling in many different cell types. Here, to directly stimulate NAADP signaling, MASTER-NAADP, a Membrane permeAble, STabilized, bio-rEversibly pRotected precursor of NAADP is synthesized and release of its active NAADP mimetic, benzoic acid C-nucleoside, 2'-phospho-3'F-adenosine-diphosphate, by esterase digestion is confirmed. In the presence of NAADP receptor HN1L/JPT2 (hematological and neurological expressed 1-like protein, HN1L, also known as Jupiter microtubule-associated homolog 2, JPT2), this active NAADP mimetic releases Ca2+ and increases the open probability of type 1 ryanodine receptor. When added to intact cells, MASTER-NAADP initially evokes single local Ca2+ signals of low amplitude. Subsequently, also global Ca2+ signaling is observed in T cells, natural killer cells, and Neuro2A cells. In contrast, control compound MASTER-NADP does not stimulate Ca2+ signaling. Likewise, in cells devoid of HN1L/JPT2, MASTER-NAADP does not affect Ca2+ signaling, confirming that the product released from MASTER-NAADP is a bona fide NAADP mimetic.

Evaluating Patient-Reported Adherence And Safety for Oral Contraception Treatment in Women via a Direct-To-Consumer Prescription Platform: A Cross-Sectional Study.

Background: The acceptance of telemedicine in the German health care system is growing. This also extends to gynecological applications such as the prescription of contraceptives. This study investigates the contraceptive use and adherence of patients using a direct-to-consumer (DTC) prescription platform for oral contraception. Methods: A retrospective cross-sectional study was conducted using anonymized data obtained from a DTC prescription platform between May 2021 and March 2023. The patient-reported outcome was evaluated after 3 months through a follow-up questionnaire. Results: In total, 8,065 patient records were available and 1,008 patients responded to the follow-up questionnaire. Patients were mostly taking combined oral contraceptives (COCs) and only 6% were taking a progestin-only pill (POP). Even in patient populations at higher risk, such as smokers and obese women, the proportion of POP users was less than 20%. Over 90% of users reported that they took the pill without any intake errors, with the main intake error being forgotten intake. Overall, 23% of patients reported adverse events while taking the pill, with POP users reporting more adverse events than COC users (36.7% vs. 22.2%). Over 70% of patients regularly attended cervical screening. Conclusions: Users of a DTC prescribing platform exhibit strong adherence, with over 90% successfully taking oral contraceptive pills. The platform effectively identifies absolute contraindications but could enhance recommendations for contraceptives in the presence of relative contraindications. For healthy women familiar with pill usage, DTC platforms offer a viable and convenient alternative to traditional doctor's office prescriptions.

Patterns of Chemsex Substance Use and Its Association with HIV Transmission Risk Among Men Who Have Sex with Men in Thailand: A Latent Class Analysis.

Sexualized substance use or "chemsex" may contribute to the HIV epidemic among men who have sex with men (MSM) in Thailand. Specific patterns of chemsex use may be associated with different HIV/STI transmission risks. We examined typologies and correlates of sexualized substance use among a sample of high-risk MSM (n = 532) who had attended a private sex party or circuit party in the past three years using latent class analysis. Multinomial regression was used to adjust for variables associated with the 3-class latent class model. We identified a 3-class model as the best fitting model, which included: (1) "negligible sexualized substance users" (36.7%), who had never engaged in chemsex in the past six months; (2) "sexualized substance users" (13.9%), who had a high level of sexualized alcohol use and a wide range of other substances before or during sex in the past six months; and (3) "exclusive chemsex users" (49.4%), who predominantly used crystal methamphetamine, amyl nitrite, and erectile dysfunctional drugs before or during sex in the past six months. Compared to negligible sexualized substance users, exclusive chemsex users were more likely to be HIV-positive, more likely to have six or more sexual partners in the past six months, less likely to have condom use at last anal intercourse, and more likely to have provided sex work. Relative to negligible sexualized substance users, sexualized substance users reported more frequent online sex-seeking behaviors. These subgroups of Thai MSM have unique substance use patterns and HIV-related risk profiles, underscoring the importance of targeted HIV prevention strategies.

Clinical pharmacology in adolescent transgender medicine.

Adolescent transgender medicine is a growing clinical field. Gender-affirming medications for transgender youth may include gonadotropin-releasing hormone (GnRH) agonists, gender-affirming hormones or both. To evaluate the potential effects of GnRH agonists (puberty suppression) on pharmacokinetic processes for transgender youth, we searched PubMed from inception to May 2024 for publications on the effects of GnRH agonists on drug absorption, distribution, metabolism or excretion for transgender adolescents or effects on hormones (including gonadotropins, adrenal androgens, sex steroids) that are associated with changes in drug metabolism during puberty in the general adolescent population. No publications discussed the effects of GnRH agonist treatment on pharmacokinetic processes for adolescent transgender people. Sixteen publications observed marked decreases in gonadotropins and sex steroids for both adolescent transgender men and adolescent transgender women and slight effects on adrenal androgens. During GnRH agonist treatment, changes in body composition and body shape were greater for adolescent transgender people than for cisgender adolescent people. Further research is needed to better understand the effects of GnRH agonists on drug metabolism and other pharmacokinetic processes for transgender adolescents receiving GnRH agonists and other gender-affirming medications.

Case report: Bridging limbic network epilepsy with psychiatric, memory, and sleep comorbidities: case illustrations of reversible psychosis symptoms during continuous, high-frequency ANT-DBS.

The network nature of focal epilepsy is exemplified by mesial temporal lobe epilepsy (mTLE), characterized by focal seizures originating from the mesial temporal neocortex, amygdala, and hippocampus. The mTLE network hypothesis is evident in seizure semiology and interictal comorbidities, both reflecting limbic network dysfunction. The network generating seizures also supports essential physiological functions, including memory, emotion, mood, and sleep. Pathology in the mTLE network often manifests as interictal behavioral disturbances and seizures. The limbic circuit is a vital network, and here we review one of the most common focal epilepsies and its comorbidities. We describe two people with drug resistant mTLE implanted with an investigational device enabling continuous hippocampal local field potential sensing and anterior nucleus of thalamus deep brain stimulation (ANT-DBS) who experienced reversible psychosis during continuous high-frequency stimulation. The mechanism(s) of psychosis remain poorly understood and here we speculate that the anti-epileptic effect of high frequency ANT-DBS may provide insights into the physiology of primary disorders associated with psychosis.

Evaluating the utility and challenges associated with "unknown" and fictional patients in the electronic medical record.

Electronic medical records (EMRs) allow for the creation of "fictional" and unknown patients within the EMR production environment. Surprisingly, there is sparse literature regarding the use cases for these patients or the challenges associated with their existence in the EMR. Here, we identified three classes of patients in regular use at our institution: true fictional patients with medical record numbers (MRNs) used to test EMR functions in the production environment, "confidential patients" used to store sensitive data, and "unknown" patients that are assigned temporary MRNs in emergency situations until additional information can be acquired. A further layer of complexity involving the merging of records for unknown patients once they are identified is also explored. Each class of patients, real or fictional, poses a variety of challenges from a clinical laboratory standpoint, which are often dealt with on a case-by-case basis. Here, we present a series of instructional cases adapted from actual patient safety events at our institution involving fictional, confidential, and unknown patient records. These illustrative cases highlight the utility of these fictional and unknown patients, as well as the challenges they pose on an institutional and individual level, including issues that arise from merging clinical data from temporary MRNs to identified patient charts. Lastly, we provide recommendations on how best to manage similar scenarios that may arise.

CT-based radiomics for predicting breast cancer radiotherapy side effects.

Skin inflammation with the potential sequel of moist epitheliolysis and edema constitute the most frequent breast radiotherapy (RT) acute side effects. The aim of this study was to compare the predictive value of tissue-derived radiomics features to the total breast volume (TBV) for the moist cells epitheliolysis as a surrogate for skin inflammation, and edema. Radiomics features were extracted from computed tomography (CT) scans of 252 breast cancer patients from two volumes of interest: TBV and glandular tissue (GT). Machine learning classifiers were trained on radiomics and clinical features, which were evaluated for both side effects. The best radiomics model was a least absolute shrinkage and selection operator (LASSO) classifier, using TBV features, predicting moist cells epitheliolysis, achieving an area under the receiver operating characteristic (AUROC) of 0.74. This was comparable to TBV breast volume (AUROC of 0.75). Combined models of radiomics and clinical features did not improve performance. Exclusion of volume-correlated features slightly reduced the predictive performance (AUROC 0.71). We could demonstrate the general propensity of planning CT-based radiomics models to predict breast RT-dependent side effects. Mammary tissue was more predictive than glandular tissue. The radiomics features performance was influenced by their high correlation to TBV volume.

Functional mapping of movement and speech using task-based electrophysiological changes in stereoelectroencephalography.

OBJECTIVE: Stereoelectroencephalography (SEEG) has become the predominant method for intracranial seizure localization. When imaging, semiology, and scalp EEG findings are not in full agreement or definitively localizing, implanted SEEG recordings are used to test candidate seizure onset zones (SOZs). Discovered SOZs may then be targeted for resection, laser ablation, or neurostimulation. If an SOZ is eloquent, resection and ablation are both contraindicated, so identifying functional representation is crucial for therapeutic decision-making. The authors present a novel functional brain mapping technique that utilizes task-based electrophysiological changes in SEEG during behavioral tasks and test this in pediatric and adult patients. METHODS: SEEG was recorded in 20 patients with epilepsy who ranged in age from 6 to 39 years (12 female, 18 of 20 patients < 21 years of age) and underwent implanted monitoring to identify seizure onset. Each performed 1) visually cued simple repetitive movements of the hand, foot, or tongue while electromyography was recorded; and 2) simple picture-naming or verb-generation speech tasks while audio was recorded. Broadband changes in the power spectrum of the SEEG recording were compared between behavior and rest. RESULTS: Electrophysiological functional mapping of movement and/or speech areas was completed in all 20 patients. Eloquent representation was identified in both cortex and white matter and generally corresponded to classically described functional anatomical organization as well as other clinical mapping results. Robust maps of brain activity were identified in healthy brain, regions of developmental or acquired structural abnormality, and SOZs. CONCLUSIONS: Task-based electrophysiological mapping using broadband changes in the SEEG signal reliably identifies movement and speech representation in pediatric and adult epilepsy patients.

Incidental dose distribution to contralateral internal mammary nodes in breast cancer patients undergoing adjuvant radiotherapy.

Background and purpose: In a relevant number of primary breast cancer patients, lymphatic drainage to the contralateral internal mammary nodes (cIMN) is being observed. Nevertheless, so far lymphatic drainage pathway to the cIMN is largely neglected during adjuvant radiotherapy. Materials and methods: This study evaluated the incidental dose to the cIMN for 120 volumetric modulated arc therapy (VMAT) treatment plans for node positive breast in dependence of internal mammary node irradiation (IMNI) and deep inspiration breath hold (DIBH). Additionally, incidental dose distribution to the cIMN based on the field design in the MA20, EORTC22922/10925 and AMAROS trials was assessed. Results: The incidental dose (Dmean ± SD) to the cIMN-CTV was 13.0 (±4.7) Gy with a maximum dose of < 30 Gy in 113/120 cases. If IMNI was included (n = 80), the Dmean to the cIMN-CTV was significantly higher compared to no IMNI, but still comparably low (n = 40; 14.3 Gy vs. 9.6 Gy; p = 0.0001). Furthermore, the dose in the cIMN during free breathing (n = 80) was higher compared to DIBH (n = 40; 13.9 Gy vs. 11.2 Gy; p = 0.002).Simulated treatment plans based on the randomized RNI trials revealed neglectable dose coverage of the cIMN (Dmean 1.0-1.8 Gy) for all protocols. Conclusion: Neither in the randomized RNI trials nor during contemporary treatment techniques clinically relevant dose distribution to the cIMN was observed. Further studies are warranted to assess the potential impact of intended irradiation of cIMN in high-risk patients.

Ideal suturing technique for robot-assisted microsurgical anastomoses.

The development of novel robotic devices specifically designed for open microsurgery leads to increasing applications in reconstructive procedures. While initial studies revealed improved precision and surgical ergonomics upon robotic assistance, surgical time was consistently observed to be increased. This study compares two robotic suturing techniques using the Symani Surgical System and RoboticScope in a preclinical setting, to further leverage the benefits of novel robotic devices in microsurgery. Six experienced microsurgeons performed three microvascular anastomoses with a "steady-thread" suturing technique and a "switch-thread" technique on 1.0-mm-diameter artificial silicone vessels. Time for anastomosis and participant's satisfaction with the techniques and robotic setup were recorded. Anastomosis quality and microsurgical skills were assessed using the Anastomosis Lapse Index and Structured Assessment of Microsurgery Skills. Lastly, technical error messages and thread ruptures were quantified. Knot tying was significantly faster and evaluated significantly better by participants using the steady-thread technique (4.11 ± 0.85 vs. 6.40 ± 1.83 min per anastomosis). Moreover, microsurgical skills were rated significantly better using this technique, while both techniques consistently led to high levels of anastomosis quality (2.61 ± 1.21 vs. 3.0 ± 1.29 errors per anastomosis). In contrast, the switch-thread technique was associated with more technical error messages in total (14 vs. 12) and twice as many unintended thread ruptures per anastomosis (1.0 ± 0.88 vs. 0.5 ± 0.69). This study provides evidence for the enhanced performance of a steady-thread suturing technique, which is suggested to be applied upon robot-assisted microsurgical procedures for optimized efficiency.

A survey of cancer patients' interest in undertaking exercise to promote relaxation during radiotherapy for breast cancer and metastatic cancer.

BACKGROUND: Approximately 25-50% of patients undergoing radiotherapy (RT) experience psychological distress and anxiety, which can detrimentally affect both their quality of life and treatment outcomes. While previous research has demonstrated that relaxation exercises can enhance the tolerability of RT and alleviate associated stress and anxiety, the specific needs for such therapies in radiation oncology remain under-explored. This study aims to investigate the demand for and preferences toward relaxation exercises among radiotherapy patients, addressing a critical gap in patient-centered care. METHODS: A prospective pseudonymized survey study using a one-time paper-based questionnaire was conducted from 2022 to 2023 among patients undergoing curative-intent RT for breast cancer or patients undergoing palliative RT for bone metastases. Patients were asked in a 11-item questionnaire about their anxiety, pre-existing practice of relaxation exercises/interventions, their interest in relaxation exercises, and preferences on the type and format of instruction. Data were analyzed descriptively. RESULTS: 100 patients (74 female and 26 male) responded, of whom 68 received curative-intent adjuvant RT and 32 palliative RT. Median age was 62 years. 78% of patients indicated a desire to be actively involved in their radiotherapy, but only 27% had used relaxation exercises prior to RT. 44.8% of both curatively and palliatively treated patients who wanted to be actively involved in their therapy desired to learn how to best relax. 56.4% of respondents were willing to spend extra time learning offered exercises. CONCLUSION: The survey indicates that patients undergoing RT, both for curative or palliative intent, desire relaxation exercises to relieve stress and anxiety from RT. It is therefore important to assess the need for relaxation interventions in individual patients and to develop suitable programs or collaborate with other healthcare professionals to meet these needs.
