Quality of life in patients with malignant spinal cord compression: a systematic review.

INTRODUCTION: Malignant spinal cord compression (MSCC) is an oncological emergency that may result in a devastating combination of malignancy and disability. Existing quality of life (QoL) questionnaires commonly used in MSCC literature (EORTC QLQ-C30, BM-22, Brief Pain Inventory, and Spine Oncology Study Group Outcomes) may not capture all the commonly reported symptoms and lack specificity to MSCC. The primary objective of this systematic review is to determine unmet patient needs and underreported QoL issues and compile a comprehensive list of QoL issues. The secondary objective of this review is to compile all existing QoL tools and questionnaires and determine whether any QoL issues are not addressed in the existing tools currently used in the literature. METHODS: A literature search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases between 1946 and February 6, 2023, to compile all QoL issues and existing questionnaires used to assess QoL in patients with MSCC. All study designs were included given that they discussed QoL issues specific to patients with MSCC. RESULTS: The results of this systematic review identified the most frequently discussed QoL issues in the literature studying MSCC. This included direct symptoms of MSCC such as back pain, paralysis, limb weakness/numbness, and urinary/bowel incontinence. Indirect symptoms coming from radiotherapy treatment such as dysphagia, painful swallowing, mouth pain, dry mouth, diarrhea, fatigue, and nausea/vomiting were also noted. Other symptoms resulting from corticosteroid treatment included difficulty sleeping, blurring of vision, weight gain, and mood disturbance. Patients also experienced psychosocial issues such as anxiety, depression, emotional distress, low self-esteem, concerns about dependence on others, concerns about getting home, and fear about their prognosis and future. CONCLUSION: This review highlights the QoL issues specific to patients with MSCC and QoL tools capturing these issues. Relevance of QoL issues identified in this systematic review must be prospectively validated by patients and healthcare professionals with experience in treating MSCC.

Quality of life issues in patients with bone metastases: A systematic review.

INTRODUCTION: Bones are frequent sites of metastatic disease, observed in 30-75% of advanced cancer patients. Quality of life (QoL) is an important endpoint in studies evaluating the treatments of bone metastases (BM), and many patient-reported outcome tools are available. The primary objective of this systematic review was to compile a list of QoL issues relevant to BM and its interventions. The secondary objective was to identify common tools used to assess QoL in patients with BM, and the QoL issues they fail to address. METHODS: A search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases between 1946 and 27 January 2023 with the keywords "bone metastases", "quality of life", and "patient reported outcomes". Specific QoL issues in original research studies and the QoL tools used were extracted. RESULTS: The review identified the QoL issues most prevalent to BM in the literature. Physical and functional issues observed in patients included pain, interference with ambulation and daily activities, and fatigue. Psychological symptoms, such as helplessness, depression, and anxiety were also common. These issues interfered with patients' relationships and social activities. Items not mentioned in existing QoL tools were related to newer treatments of BM, such as pain flare, flu-like symptoms, and jaw pain due to osteonecrosis. CONCLUSIONS: This systematic review highlights that QoL issues for patients with BM have expanded over time due to advances in BM-directed treatments. If they are relevant, additional treatment-related QoL issues identified need to be validated prospectively by patients and added to current assessment tools.

Assessment of stromal tumor infiltrating lymphocytes and immunohistochemical features in invasive micropapillary breast carcinoma with long-term outcomes.

PURPOSE: We studied the long-term outcomes of invasive micropapillary carcinoma (IMPCs) of the breast in relation to stromal tumor infiltrating lymphocytes (sTILs), prognostic biomarkers and clinicopathological features. METHODS: Stage I-III IMPCs treated with upfront surgery at our institution (January 2000 and December 2016) were included. Central pathology review was performed and sTILs (including zonal distribution and hot spot analysis) and tumor-associated plasma cells (TAPC) were evaluated. Expression of P53, BCL2, FOXP3, and WT1, which are variably linked to breast cancer prognosis, was measured by immunohistochemistry using tissue microarrays. Time-to-event endpoints were distant recurrence free interval (DRFI) and breast cancer-specific survival (BCSS). RESULTS: We included 111 patients of whom 59% were pure IMPCs. Standard clinicopathological features were comparable between pure and non-pure IMPCs. Overall, the mean sTILs level was 20% with higher proportion of sTILs present at the invasive front. There were no significant differences between pure- and non-pure IMPCs in sTILs levels, nor in the spatial distribution of the hot spot regions or in the distribution of TAPC. Higher sTILs correlated with worse DRFI (HR = 1.55; p = 0.0172) and BCSS (HR = 2.10; p < 0.001). CONCLUSIONS: Clinicopathological features, geographical distribution of sTILs and TAPC are similar between pure and non-pure IMPCs. Despite a high proportion of grade 3 tumors and lymph node involvement, we observed a low rate of distant recurrences and breast cancer-related death in this cohort of stage I-III IMPCs treated with primary surgery. Caution in interpretation of the observed prognostic correlations is required given the very low number of events, warranting validation in other cohorts.

Evaluation of boost irradiation in patients with intermediate-risk stage III Wilms tumour with positive lymph nodes only: Results from the SIOP-WT-2001 Registry.

OBJECTIVE: To evaluate the value of radiotherapy boost omission in patients with intermediate-risk, stage III Wilms tumours (WT) with positive lymph nodes (LN). METHODS AND MATERIALS: All patients with intermediate-risk, stage III (LN positive) WT consecutively registered in the SIOP-WT-2001 study were included in this analysis. Endpoints were 5-year event-free survival (EFS), loco-regional control (LRC) and overall survival (OS). RESULTS: Between June 2001 and May 2015, 2,569 patients with stage I to III WT after preoperative chemotherapy were registered in the SIOP-WT-2001 study. Five hundred and twenty-three (20%) had stage III disease, of which 113 patients had stage III due to positive LN only. Of those, 101 (89%) received radiotherapy, 36 of which (36%) received, apart from flank irradiation, a boost dose to the LN positive area. Four patients (4%) did not receive any adjuvant radiotherapy. In eight patients information on radiotherapy was not available. With a median follow-up of 71 months, no difference in 5-year EFS (84% vs. 83%, P = 0.77) and LRC (96% vs. 97%, P = 0.91) was observed between patients receiving a radiotherapy boost and those without boost, respectively. Five-year OS, including salvage therapy, was excellent (boost vs. no boost: 97% vs. 95%, P = 0.58). CONCLUSIONS: Outcome data demonstrate that omission of the radiotherapy boost to the loco-regional positive lymph nodes in patients with intermediate-risk, stage III WT who receive preoperative chemotherapy and postoperative flank irradiation (14.4 Gy) can be considered a safe approach for future SIOP protocols.

Hemostatic radiotherapy: a narrative review of the literature.

BACKGROUND AND OBJECTIVE: In locally advanced cancer, bleeding is a common clinical presentation and radiotherapy (RT) provides a noninvasive, well-tolerated, cost-effective treatment. However, the choice for fractionation dose and schedule seem to merely depend on physician's preference rather than specific guidelines. We reviewed the available literature on palliative hemostatic RT for response rate (RR) and bleeding duration in relation with the given dose. METHODS: The PubMed database was used to search for articles, which were assessed by predetermined inclusion and exclusion criteria. A total of 54 articles, published over the last 20 years until December 2023 were analyzed for dose and/or fractionation regimen and their relation to the RR. KEY CONTENT AND FINDINGS: A variety of fractionation schedules are used for palliative symptom control, including hemostasis. Research focusing on hemostatic irradiation specifically and prospective studies are rare. Moreover, to our knowledge, there are no specific (prospective) studies ongoing. Both external beam radiotherapy (EBRT) and brachytherapy lead to bleeding control and daily or weekly hypofractionated irradiation is safe and effective for both high and low biological equivalent dose (BED) regimens. If feasible, based on patient condition, some studies favor higher BED regimens to obtain more durable tumor/higher bleeding response. Higher radiation dose for thoracic irradiation may be indicative for simultaneous presentation of obstruction and/or dysphagia. Brachytherapy may be used solely or in combination with EBRT or in the setting of re-irradiation. Short-course regimens are preferred in patients in with low performance index scores. For future studies, multivariate analysis, including BED, can be important to assess efficacy of different fractionation schedules for a variety of tumor etiologies. CONCLUSIONS: Hemostatic RT, both by EBRT and brachytherapy, appears to be a safe and effective palliative treatment that clinically and statistically significantly reduces bleeding in cancer patients. The available literature is limited regarding prospective and uniform evaluation of hemostatic RT, including fractionation schedules. BED seems to be indicative for a better RR for specific indications. Current evidence suggests that treatment decisions should be tailored according to the patients' condition, tumor etiology and other clinical symptoms. More (prospective) research focusing on hemostasis is necessary to develop clear guidelines.

Death rattle: current experiences and non-pharmacological management-a narrative review.

BACKGROUND AND OBJECTIVE: Death rattle (DR) is a common symptom in dying patients, caused by secretions in the upper airway. Experiences regarding DR differ among patients, relatives, and health professionals. However, evidence of patients', relatives', and health professionals' needs for DR management in order to improve their experiences is lacking. In addition, little is known about the actual effects of non-pharmacological interventions on DR intensity or DR-related distress. This narrative review aims to explore (I) the experiences and needs of patients, relatives, and health professionals regarding DR sound and its management; and (II) studies on non-pharmacological interventions in DR management. METHODS: Based on a PubMed literature search with the free-text term "death rattle", nine studies published in the last ten years were included. KEY CONTENT AND FINDINGS: No significant correlation between DR intensity and patients' respiratory distress could be found. Some relatives experience high levels of distress and express a need for DR care improvement. Health professionals are often influenced in their decision-making to intervene by external pressure or their need 'to do something'. Both repositioning and explaining DR to relatives are seen as useful first-line non-pharmacological interventions by health professionals. The severity of DR does not improve when suctioning is performed before starting anticholinergics. CONCLUSIONS: Variation in DR-related experiences and needs exists among relatives and health professionals. More research is needed into the effectiveness of non-pharmacological interventions for DR management and the most suitable measurement tools to objectify DR-related outcomes.

Burnout of healthcare professionals in supportive and palliative care: a summary of recent literature.

PURPOSE OF REVIEW: Burnout is a complex phenomenon where several personal and work-related factors interact with each other. Palliative care is a challenging branch of healthcare, which can be especially demanding for the professionals providing it. This review presents an overview of the most recent literature on causes, identification, and consequences of burnout as well as articles on interventions to reduce burnout in the professional palliative healthcare provider setting. RECENT FINDINGS: With a few exceptions, research on burnout in the palliative care provider setting is focused on further insight on the different aspects that cause burnout on an individual, social, and organizational level. Unfortunately, only a few studies were found on interventions to prevent burnout. While the results of these interventions were promising, long-term results or data on how these diminish actual healthcare provider dropout were not available. SUMMARY: Research on burnout faced by palliative healthcare professionals seems to focus mainly on gaining further insight of different aspects of the complex syndrome that is burnout and how different individual, social, and organizational factors interact with each other. Further research on the prevention and treatment of burnout is necessary.

Patient-reported outcomes versus proxy-reported outcomes in supportive and palliative care: a summary of recent literature.

PURPOSE OF THE REVIEW: Patient-reported outcomes are one of the most valuable clinical outcome measures. In palliative care, however, they are often difficult to retrieve. Therefore, proxy-reported outcomes are sometimes used as a surrogate. As there have been concerns about the validity of these by-proxy reports, the authors reviewed the most recent literature for the most recent insights in using proxy-reported outcomes. RECENT FINDINGS: The authors found very little new research on patient versus proxy-reported outcomes in palliative care. The results of the studies the authors found seem to correlate with older evidence concluding that there are many factors influencing a discrepancy between patients' outcomes and how this is perceived by their proxies, such as the well-being paradox, caregiver burden, and the proxies' own mental well-being. SUMMARY: While proxies' opinions and knowledge of the patients' values are important factors to consider, proxy-reported outcomes should be used with caution and viewed as a complementary perspective rather than a true substitute for the individual patient's outcome.

The use of electronic Patient Reported Outcomes in follow-up after palliative radiotherapy: A survey study in Belgium.

Objective: Electronic Patient-Reported Outcome Measures (ePROMs) could be used to monitor patients' symptoms after treatment. However, ePROM implementation in clinical practice has been challenging, especially in (palliative) radiation oncology. The aim of this study was to explore the opinions of healthcare providers (HCP) active in radiation oncology in Belgium on the use of ePROMs for symptom follow-up after palliative radiotherapy. Methods: An anonymous online survey was conducted with different HCP in radiation oncology in Belgium. Participants were recruited through several professional organizations with approximately 390 members actively working in the field of radiation oncology. The survey used was a self-developed questionnaire, based on existing literature on implementation of (e)PROMs in cancer care, our previous research on this topic as well as our personal experience in the field of oncology and palliative care. Results: Of the 128 respondents, 26% had experience with ePROMs in clinical practice. Eighty-four percent considered ePROMs beneficial for patients' health and symptom knowledge, symptom self-management and active participation in care. ePROMs could help HCP to focus on detection of relevant symptoms and improve their management. Almost 75% were willing to implement and use ePROMs. Assigning ePROM introduction and follow-up to a dedicated person, such as a nurse navigator, was suggested to promote ePROM implementation and use in clinical practice. Conclusion: Despite limited experience with ePROMs in clinical care for palliative radiotherapy patients, the majority of respondents is willing to implement and use ePROMs for this particular patient population. Innovation: This is one of the first studies specifically focusing on experiences and opinions of HCP in radiation oncology on the use of ePROMs for symptom follow-up in palliative radiotherapy. HCP should be actively involved in implementation of ePROMs after palliative radiotherapy, to translate their vision of their ideals in practice.

"Scan-(pre)Plan-Treat" Workflow for Bone Metastases Using the Ethos Therapy System: A Single-Center, In Silico Experience.

Purpose: To report on the accuracy of automated delineation, treatment plan quality, and duration of an in-silico "scan-(pre)plan-treat" (SPT) workflow for vertebral bone metastases using a 1 × 8 Gy regimen. Method and Materials: The cloud-based emulator system of the Ethos therapy system was used to adapt an organ-at-risk-sparing preplan created on the diagnostic CT to the anatomy-of-the-day using the cone beam CT made before treatment. Results: SPT using the Ethos emulator system resulted in relatively good coverage of the PTV and acceptable dose to the OAR. Delivery time and plan homogeneity was the best for 7-field IMRT plan template. Conclusions: A SPT workflow formula results in a highly conformal treatment delivery while maintaining an acceptable timeframe for the patient on the treatment couch.

Development of a Patient Decision Aid for Rectal Cancer Patients with Clinical Complete Response after Neo-Adjuvant Treatment.

Surgery is the primary component of curative treatment for patients with rectal cancer. However, patients with a clinical complete response (cCR) after neo-adjuvant treatment may avoid the morbidity and mortality of radical surgery. An organ-sparing strategy could be an oncological equivalent alternative. Therefore, shared decision making between the patient and the healthcare professional (HCP) should take place. This can be facilitated by a patient decision aid (PtDA). In this study, we developed a PtDA based on a literature review and the key elements of the Ottawa Decision Support Framework. Additionally, a qualitative study was performed to review and evaluate the PtDA by both HCPs and former rectal cancer patients by a Delphi procedure and semi-structured interviews, respectively. A strong consensus was reached after the first round (I-CVI 0.85-1). Eleven patients were interviewed and most of them indicated that using a PtDA in clinical practice would be of added value in the decision making. Patients indicated that their decisional needs are centered on the impact of side effects on their quality of life and the outcome of the different options. The PtDA was modified taking into account the remarks of patients and HCPs and a second Delphi round was held. The second round again showed a strong consensus (I-CVI 0.87-1).

Bowel obstruction in advanced tubo-ovarian cancer: a retrospective cohort study.

Ten to fifty percent of women with advanced or recurrent ovarian cancer develop malignant bowel obstruction (MBO). We described the management and examined the complications and survival of MBO in primary epithelial tubo-ovarian cancer patients. Materials and methods: The authors conducted a retrospective monocentric cohort study of tubo-ovarian cancer patients diagnosed with MBO between January 1st, 2011 until August 31st, 2017 at the University Hospitals Leuven, Belgium. Results: Seventy-three patients with a total of 165 MBO episodes (median 1/patient; range 1-14) were included. The median time interval between cancer diagnosis and first MBO episode was 373 days (range 0-1937). The median time interval between MBO episodes was 44 days (range 6-2004). Complications were bowel perforation (n=5; 7%) and bowel ischemia (n=1; 1%). Conservative treatment was applied in 150 (91%) episodes, including gastrostomy in 4 (2%) episodes and octreotide in 79 (48%) episodes. Surgery was necessary in 15 (9%) episodes. Total parenteral nutrition was administered in 16 (22%) patients. During the study period 62 (85%) patients died (median 167 days since first MBO; range 6-2256). A significant difference in survival was found regarding the tumor marker CA 125 at cancer diagnosis, the use of palliative chemotherapy after the first episode of MBO and palliative surgical treatment for MBO in a group of well selected patients. Conclusion: Tubo-ovarian cancer patients with MBO have a poor prognosis: 85% of the study population died within a relatively short time interval since the first MBO. In our study population, the majority of patients with MBO were treated conservatively. Both palliative chemotherapy and palliative surgical management are considerable treatment options depending on the individual patient profile.

The Upgrade Risk of B3 Lesions to (Pre)Invasive Breast Cancer After Diagnosis on Core Needle or Vacuum Assisted Biopsy. A Belgian National Cohort Study.

INTRODUCTION: Flat epithelial atypia (FEA), lobular neoplasia (LN), papillary lesions (PL), radial scar (RS) and atypical ductal hyperplasia (ADH) are lesions of uncertain malignant potential and classified as B3 lesions by the European guidelines for quality assurance in breast cancer screening and diagnosis. Current management is usually wide local excision (WE), surveillance may be sufficient for some. We investigated the upgrade rate of B3 lesions to breast malignancy in a subsequent resection specimen after diagnosis on core needle-or vacuum assisted biopsy (CNB-VAB) in a national population-based series. METHODS: Using data from the Belgian Cancer Registry (BCR) between January 1, 2013 and December 31, 2016, inclusion criteria were new diagnosis of a B3 lesion on CNB or VAB with subsequent histological assessment on a wider excision specimen. Histological agreement between first- and follow-up investigation was analyzed to determine the upgrade risk to ductal adenocarcinoma in situ (DCIS) or invasive breast cancer (IC) according to the type of B3 lesion. RESULTS: Of 1855 diagnosed B3 lesions, 812 were included in this study: 551 after CNB-261 after VAB. After diagnosis on CNB and VAB, we found 19.0% and 14.9% upgrade to malignancy respectively. Upgrade risks after CNB and VAB were: FEA 39.5% and 17.6%; LN 40.5% and 4.3%; PL 10.4% and 12.5%; RS 25.7%and 0.0%; ADH 29.5% and 20.0%. CONCLUSION: Based on the observed upgrade rate we propose three recommendations: first, resection of ADH, and FEA with WE; second, resection of RS and classical LN with therapeutic VAB and further surveillance when radio-pathological correlation is concordant; third, surveillance of PL.

Palliative whole brain radiation therapy: an international state of practice.

BACKGROUND: Improvements in radiation delivery and systemic therapies have resulted in few remaining indications for palliative whole brain radiation therapy (WBRT). Most centers preferentially use stereotactic radiotherapy (SRT) and reserve WBRT for those with >15 lesions, leptomeningeal presentation, rapidly progressive disease, or limited estimated survival. Despite regional differences among preferred dose, fractionation, and treatment technique, we predict survival post-WBRT will remain poor-indicating appropriate application of WBRT in this era of SRT and improved systemic therapies. METHODS: A multi-center, international retrospective analysis of patients receiving WBRT in 2022 was performed. Primary end point was survival after WBRT. De-identified data were analyzed centrally. Patients receiving WBRT as part of a curative regimen, prophylactically, or as bridging therapy were excluded. The collected data consisted of patient parameters including prescription dose and fractionation, use of neurocognitive sparing techniques and survival after WBRT. Survival was calculated via the Kaplan-Meier method. RESULTS: Of 29,943 international RT prescriptions written at ten participating centers in 2022, 462 (1.5%) were for palliative WBRT. Participating centers were in the United States (n=138), the United Kingdom (n=111), Hong Kong (n=72), Italy (n=49), Belgium (n=45), Germany (n=27), Ghana (n=15), and Cyprus (n=5). Twenty-six different dose regimens were used. The most common prescriptions were for 3,000 cGy over 10 fractions (45.0%) and 2,000 cGy over 5 fractions (43.5%) with significant regional preferences (P<0.001). Prior SRT was delivered in 32 patients (6.7%), hippocampal avoidance (HA) was used in 44 patients (9.5%), and memantine was prescribed in 93 patients (20.1%). Survival ranged from 0 days to still surviving at 402 days post-treatment. The global median overall survival (OS) was 84 days after WBRT [95% confidence interval (CI): 68.0-104.0]. Actuarial survival at 7 days, 1 month, 3 months, and 6 months were 95%, 78%, 48%, and 32%, respectively. Twenty-seven patients (5.8%) were unable to complete their prescribed WBRT. CONCLUSIONS: This moment-in-time analysis confirms that patients with poor expected survival are being appropriately selected for WBRT-illustrating the dwindling indications for WBRT-and demonstrates the variance in global practice. Since poor survival precludes patients from deriving benefit, memantine and HA are best suited in carefully selected cases.

Latest clinical research in leptomeningeal disease (LMD)-a narrative review.

BACKGROUND AND OBJECTIVE: Leptomeningeal disease (LMD) is associated with poor survival and health-related quality of life (HRQoL). There is an urgent need for clinical research in this area to improve the outcomes. The purpose of this study is to summarize the areas of active clinical research in LMD, identify the knowledge gap, and suggest future research directions. METHODS: A narrative review of clinical trials in LMD was conducted based on a search in clinicatrials.gov using the search term "leptomeningeal" under "condition or disease". Clinical trials in patients with LMD arising from solid malignancy that were labelled as "not yet recruiting", "recruiting", "enrolling by invitation" or "active, not recruiting" were included. Studies which were deemed to have significant impact on future research direction in LMD were selected for discussion. KEY CONTENT AND FINDINGS: A total of 38 clinical trials were included. Of these 38 trials, 19 are discussed in this review, with focus on their research questions and impact on future research directions. Most of the studies that were not selected for discussion focused on biomarker-driven interventions. Four key areas of research were identified, namely the (I) diagnosis, response assessment or molecular profiling of LMD (n=2); (II) advances in radiotherapy (n=3); (III) intrathecal treatment (n=13); (IV) novel drug carrier for systemic treatment (n=1). The research questions in the 19 discussed clinical trials included the tumour microenvironment of LMD, the role of novel molecular techniques in LMD, combination of radiotherapy with drugs, and cell-based immunotherapy. Among these 19 studies, 11 were phase 1 trials, 3 were phase 2 or phase 1/2 trials, 2 were phase 3 or phase 2/3 trials and the study phase was not reported in the remaining 3 studies. The existing knowledge gaps are discussed, including the lack of primary site-specific prognostic tools, cost-effectiveness studies, dedicated HRQoL assessment tools for LMD and sequencing of treatment. CONCLUSIONS: The current clinical trials in LMD offer the promise to improve the diagnosis and treatment outcomes of patients with LMD. More research is needed to overcome the potential hurdles in the current treatment and bridge the knowledge gaps as identified in this review, to improve patients' quantity and quality of survival.

Appropriateness of the 30-day expected mortality metric in palliative radiation treatment: a narrative review.

BACKGROUND AND OBJECTIVE: The 30-day expected mortality rate is frequently used as a metric to determine which patients benefit from palliative radiation treatment (RT). We conducted a narrative review to examine whether its use as a metric might be appropriate for patient selection. METHODS: A literature review was conducted to identify relevant studies that highlight the benefits of palliative RT in timely symptom management among patients with a poor performance status, the accuracy of predicting survival near the end of life and ways to speed up the process of RT administration through rapid response clinics. KEY CONTENT AND FINDINGS: Several trials have demonstrated substantial response rates for pain and/or bleeding by four weeks and sometimes within the first two weeks after RT. Models of patient survival have limited accuracy, particularly for predicting whether patients will die within the next 30 days. Dedicated Rapid Access Palliative RT (RAPRT) clinics, in which patients are assessed, simulated and treated on the same day, reduce the number of patient visits to the radiation oncology department and hence the burden on the patient as well as costs. CONCLUSIONS: Single-fraction palliative RT should be offered to eligible patients if they are able to attend treatment and could potentially benefit from symptom palliation, irrespective of predicted life expectancy. We discourage the routine use of the 30-day mortality as the only metric to decide whether to offer RT. More common implementation of RAPRT clinics could result in a significant benefit for patients of all life expectancies, but particularly those having short ones.

Stereotactic body radiation therapy versus conventional external beam radiotherapy for spinal metastases: A systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: This study aimed to compare SBRT and cEBRT for treating spinal metastases through a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: PubMed, EMBASE and Cochrane Library were searched up to 6 May 2023 for RCTs comparing SBRT and cEBRT for spinal metastases. Overall and complete pain response, local progression, overall survival, quality of life and adverse events were extracted. Data were pooled using random-effects models. Results were reported as risk ratios (RRs) for dichotomous outcomes, and hazard ratios (HRs) for time-to-event outcomes, along with their 95% confidence intervals (CIs). Heterogeneity was evaluated using the I2 statistic. RESULTS: Three RCTs were identified involving 642 patients. No differences were seen in overall pain response comparing SBRT and cEBRT (RR at 3 months: 1.12, 95% CI, 0.74-1.70, p = 0.59; RR at 6 months: 1.29, 95% CI, 0.97-1.72, p = 0.08). Only two of three studies presented complete pain response data. SBRT demonstrated a statistically significant improvement in complete pain response compared to cEBRT (RR at 3 months: 2.52; 95% CI, 1.58-4.01; P < 0.0001; RR at 6 months: 2.48; 95% CI, 1.23-4.99; P = 0.01). There were no significant differences in local progression and overall survival. Adverse events were similar, except for any grade radiation dermatitis, which was significantly lower in SBRT arm (RR 0.17, 95% CI 0.03-0.96, P = 0.04). CONCLUSION: SBRT is a safe treatment option for spine metastases. It may provide better complete pain response compared to cEBRT. Additional trials are needed to determine the potential benefits of SBRT in specific patient subsets.

A critical appraisal of the four systematic reviews and meta-analysis on stereotactic body radiation therapy versus external beam radiotherapy for painful bone metastases and where we go from here.

Radiotherapy is an important treatment modality for pain control in patients with bone metastases. Stereotactic body radiation therapy (SBRT), which allows delivering a much higher dose per fraction while sparing critical structures compared to conventional external beam radiotherapy (cEBRT), has become more widely used, especially in the oligometastatic setting. Randomized controlled trials (RCTs) comparing the pain response rate of SBRT and cEBRT for bone metastases have shown conflicting results, as have four recent systematic reviews with meta-analyses of these trials. Possible reasons for the different outcomes between these reviews include differences in methodology, which trials were included, and the endpoints examined and how they were defined. We suggest ways to improve analysis of these RCTs, particularly performing an individual patient-level meta-analysis since the trials included heterogeneous populations. The results of such studies will help guide future investigations needed to validate patient selection criteria, optimize SBRT dose schedules, include additional endpoints (such as the time to onset of pain response, durability of pain response, quality of life (QOL), and side effects of SBRT), and better assess the cost-effectiveness and trade-offs of SBRT compared to cEBRT. An international Delphi consensus to guide selection of optimal candidates for SBRT is warranted before more prospective data is available.

Using ePROMs for follow-up after palliative radiotherapy: An exploratory study with patients and health care providers.

OBJECTIVES: Patients treated with palliative radiotherapy may experience symptoms decreasing their quality of life. Electronic patient-reported outcome measures (ePROMs) could provide an opportunity to follow-up patients after treatment. METHODS: A mixed-method study was performed using self-constructed questionnaires, focus groups and interviews with patients and health care professionals (HCP). A qualitative approach was used to code the data. RESULTS: Forty-two patients, 21 radiation-oncologists, 15 general practitioners (GPs) and 24 home-care nurses completed a questionnaire. Ten patients, 6 radiation-oncologists, 14 GPs and 5 nurses were interviewed or participated in a focus group. Although patients and HCP are satisfied with current care, they believe ePROMs could improve follow-up, communication, continuity of care and self-management of symptoms. An easy to use, versatile ePROM platform seems to be important for successful implementation. Self-care tips and contact information should be added to relevant ePROM-questions, on both physical and psychological symptoms. CONCLUSION: Patients and HCP agree that ePROMs could improve systematical clinical follow-up after palliative radiotherapy, with self-management support being the primary objective of such a system. Practice implications ePROMs after palliative radiotherapy seem feasible, the exact patient population that could benefit the most will need to be explored further; as the palliative population is very diverse.

ESTRO ACROP guidelines for external beam radiotherapy of patients with complicated bone metastases.

This is the second part of the guidelines on the management of bone metastases. In the first part, the diagnosis and management of uncomplicated bone metastases have been addressed. Bone metastases may significantly reduce quality of life due to related symptoms and possible complications. The most common symptoms include pain and neurologic deficits. The most serious complications of bone metastases are skeletal-related events (SRE), defined as pathologic fracture, spinal cord compression, pain, or other symptoms requiring an urgent intervention such as surgery or radiotherapy. Diffuse bone metastases may lead to hypercalcaemia that can be fatal if untreated. The growing access to modern diagnostic tools allows early detection of asymptomatic bone metastases that could be successfully managed with local treatment if oligometastatic or systemic treatment for diffuse bone metastases to try to avoid the development of SRE.
