Current utilisation of advanced techniques and technologies in palliative radiation therapy in Australia and New Zealand

INTRODUCTION

The techniques employed in palliative radiation therapy are highly variable, ranging from basic (2D/3D-conformal) to more advanced (beam modulation and stereotactic techniques), and their relative use has not previously been formally investigated at a national level. The purpose of this work was to assess the current utilisation of palliative techniques and technologies in Australia and New Zealand (ANZ).

METHODS

A voluntary, anonymous, internet-based, RANZCR approved survey was offered to all practising radiation oncology (RO) Fellows in ANZ. Participants selected their preferred methods of managing patients in five case studies involving bone, brain, lung metastases and locally advanced lung cancer.

RESULTS

From October 2022 to February 2023, 146 of 485 eligible participants (30%) responded. In all, 61% and 81% would treat an uncomplicated breast cancer solitary spinal metastasis with stereotactic body radiation therapy routinely and ideally, respectively; 11% and 32% would treat a solitary lung cancer brain metastasis with dedicated stereotactic radiosurgery routinely and ideally; 36% and 56% would treat multiple low-volume brain metastases with a stereotactic technique routinely and ideally. There was negligible difference in the routine and preferred use of advanced technologies for a solitary bowel cancer lung metastasis; 69% and 77% would treat a locally advanced primary lung cancer with an advanced technique routinely and ideally. Relative to Australia, NZ ROs routinely treat uncomplicated solitary spinal metastases (P < 0.001), solitary brain metastases (P < 0.001), multiple low-volume brain metastases (P < 0.02), and locally advanced primary lung cancer (P < 0.001) more commonly with basic technologies, mainly due to limited local availability of advanced technology and departmental waiting lists.

CONCLUSION

Participants generally favoured treating with advanced techniques and technologies in palliative settings, if available, but there were notable disparities between the two countries. Enhanced local access and clinical training may facilitate optimal utilisation of advanced technologies and improve clinical outcomes.

Outcomes of patients receiving urgent palliative radiotherapy for advanced lung cancer: an observational study

BACKGROUND

There is considerable variability in the management of patients with advanced lung cancer referred for palliative radiotherapy owing to uncertainties in prognosis and the benefit of treatment. This study presents the outcomes of patients seen in the Fast Track Lung Clinic, an urgent access palliative radiotherapy clinic, and aims to identify factors associated with treatment response and survival.

METHODS

Consecutive patients with advanced lung cancer seen in the Fast Track Lung Clinic between January 2014 and July 2020 were included. Patients who underwent radiotherapy were contacted beginning 30 days after radiotherapy to evaluate treatment response. Cluster bootstraps were used to compute confidence intervals for treatment response rate. Prognostic factors for treatment response and overall survival were identified using multivariable generalized estimating equations and Cox regression models, respectively.

RESULTS

A total of 558 patients were included, of whom 459 (82.3%) consented to palliative radiotherapy for 1053 indications. The overall treatment response rate was 70.0% (95% CI, 65.8-74.2) for indications with follow-up (70.8%). Higher response rates were observed in patients with better ECOG performance status (OR per point, 0.71; 95% CI, 0.55-0.93; P = 0.01 ) and EGFR-mutant non-small cell lung cancer (OR vs wild-type, 2.46; 95% CI, 1.35-4.51; P = 0.003 ), whereas patients treated for neurological symptoms had lower response rates (OR, 0.27; 95% CI, 0.16-0.45; P < 0.001 ). There was no difference in response rate between patients who died within 30 days of starting radiotherapy and those who survived longer (OR, 0.83; 95% CI, 0.42-1.67; P = 0.61 ). Age; ECOG performance status; smoking history; pathology; EGFR or ALK mutation status; and the presence of liver, adrenal, or brain metastases were associated with overall survival.

CONCLUSIONS

Palliative radiotherapy was effective for patients with advanced lung cancer, although response rates varied by patient characteristics and treatment indication. This study identified prognostic factors for radiotherapy response and overall survival that can inform treatment decisions in this population.

Treatment Terminations During Radiation Therapy: A 10-Year Experience

PURPOSE

Patients undergoing radiation therapy may terminate treatment for any number of reasons. The incidence of treatment termination (TT) during radiation therapy has not been studied. Herein, we present a cohort of TT at a large multicenter radiation oncology department over 10 years.

METHODS AND MATERIALS

TTs between January 2013 and January 2023 were prospectively analyzed as part of an ongoing departmental quality and safety program. TT was defined as any premature discontinuation of therapy after initiating radiation planning. The rate of TT was calculated as a percentage of all patients starting radiation planning. All cases were presented at monthly morbidity and mortality conferences with a root cause reviewed.

RESULTS

A total of 1448 TTs were identified out of 31,199 planned courses of care (4.6%). Six hundred eighty-six (47.4%) involved patients treated with curative intent, whereas 753 (52.0%) were treated with palliative intent, and 9 (0.6%) were treated for benign disease. The rate of TT decreased from 8.49% in 2013 to 3.02% in 2022, with rates decreasing yearly. The most common disease sites for TT were central nervous system (21.7%), head and neck (19.3%), thorax (17.5%), and bone (14.2%). The most common causes of TT were hospice and/or patient expiration (35.9%), patient choice unrelated to toxicity (35.2%), and clinician choice unrelated to toxicity (11.5%).

CONCLUSIONS

This 10-year prospective review of TTs identified a year-over-year decrease in TTs as a percentage of planned patients. This decrease may be associated with the addition of root cause reviews for TTs and discussions monthly at morbidity and mortality rounds, coupled with departmental upstream quality initiatives implemented over time. Understanding the reasons behind TTs may help decrease preventable TTs. Although some TTs may be unavoidable, open discourse and quality improvement changes effectively reduce TT incidents over time.

Palliative Radiotherapy in Non-small Cell Lung Cancer: Patterns of Use and Predictors of 30-Day Mortality in End-of-Life Care

Introduction Lung cancer is the leading cause of cancer-related deaths worldwide, with non-small cell lung cancer (NSCLC) being the most common type. More than half of patients require radiotherapy throughout their treatment. Palliative radiotherapy (PRT) is an important tool for symptom control and quality of life improvement in advanced NSCLC patients. However, the benefits of PRT must be balanced against possible disadvantages, especially in end-of-life (EOL) care. This study aims to describe the profile of PRT-treated deceased NSCLC patients, quantify the proportion of PRT recipients in the last 30 days of life and identify short-term survival prognostic factors in this group. Materials and methods This retrospective analysis was performed at two radiotherapy facilities within the Kent Oncology Centre, UK, for two years, running from January 1, 2022, to January 1, 2024. Data were collected from 857 deceased NSCLC patients who received PRT. Demographics, cancer diagnosis, histology, tumour, node, metastasis (TNM) staging, radiotherapy details, recent treatments, performance status (PS) and comorbidities were analysed. Patients have been stratified as long-term survivors (more than 30 days after PRT initiation, LTS group) along with short-term survivors (STS) (died within 30 days, STS group). Descriptive statistics, chi-squared tests, t-tests and multivariable logistic regression have been used in the data analysis. Results Out of 857 patients, 148 (17.3%) died within 30 days of PRT initiation. PS was considerably worse (p = 0.027), Adult Comorbidity Evaluation 27 (ACE-27) scores were higher (p = 0.018), and metastatic disease was more prevalent (60.1% vs. 47.5%, p = 0.02) in STS group patients. Fewer patients in the STS group completed their treatment compared to the LTS group (63.5% vs. 82.8%, p < 0.001). The STS group also received lower mean radiation dose (17.7 Gy vs. 19.6 Gy, p = 0.022) and fewer fractions (4.4 vs. 5.2, p = 0.019). The most common RT regimen in both cohorts was 20 Gy in five fractions, used in 55.4% of STS and 49.8% of LTS patients, with no significant difference in single fraction RT use between groups (33.1% in STS vs. 36.8% in LTS, p = 0.401). Multivariate logistic regression identified significant predictors of 30-day mortality: poorer PS (adjusted OR: 1.981, 95% CI: 1.33-3.12, p = 0.001), metastatic disease (adjusted OR: 2.02, 95% CI: 1.246-3.571, p = 0.002), incomplete PRT (adjusted OR: 0.337, 95% CI: 0.21-0.514, p < 0.001) and no recent chemotherapy (adjusted OR: 0.542, 95% CI: 0.342-0.941, p = 0.044). Conclusion This study demonstrated that compared with previous reports, a higher proportion of NSCLC patients who received PRT died within 30 days of treatment initiation, and low treatment adherence rates highlight challenges in EOL settings. Identification of poor PS and metastatic disease as predictors of short-term mortality would help inform PRT decision-making. The underutilisation of single-fraction radiotherapy and the link between recent chemotherapy and lower 30-day mortality warrant further study. These results highlight the need for better prognostic tools and more selective use of PRT, including increased consideration of single-fraction radiotherapy, in NSCLC patients approaching end of life and emphasise the importance of balancing benefit against treatment burden in this vulnerable population.

Aggressive anticancer treatment in the last 2 weeks of life

BACKGROUND

There is a concern that terminally ill cancer patients may be aggressively treated due to the rapidly growing possibilities of anticancer treatment. The aim of this study was to evaluate the use of anticancer treatment at the end of life (EoL).

MATERIALS AND METHODS

This retrospective study included adult patients with advanced solid cancers who were treated at the Institute of Oncology Ljubljana and died of cancer between January 2015 and December 2019. A multiple logistic regression model was used to assess an association between the aggressiveness of anticancer treatment (i.e. systemic therapy, radiotherapy and surgery) in the last 2 weeks of life and year of death, age at death, sex, prognosis of cancer and enrolment into the specialist palliative care (SPC).

RESULTS

We included 1736 patients in our analysis. Overall, 13.7% of patients were enrolled into the SPC and 14.4% received anticancer treatment in the last 2 weeks of life. The odds of receiving anticancer treatment significantly increased over time [odds ratio (OR) 1.15, 95% confidence interval (CI) 1.04-1.27]. There was an increased use of novel systemic therapy (e.g. small-molecule targeted therapy and immunotherapy) at the EoL. Older patients had significantly lower odds to receive anticancer treatment in the last 2 weeks of life as compared to younger patients (OR 0.96, 95% CI 0.95-0.98). As compared to patients receiving only a standard oncology care, those also enrolled into the SPC had significantly lower odds for anticancer treatment in the last 2 weeks of life (OR 0.22, 95% CI 0.12-0.43).

CONCLUSIONS

Terminally ill cancer patients have increased odds for receiving anticancer treatment, especially novel systemic therapies, in the last 2 weeks of life. Younger patients and those not enrolled into the SPC are at particular risk for anticancer treatment at the EoL.

Audit of 30-day mortality following palliative radiotherapy: are we able to improve patient care at the end of life?

Background

Several measurements defining the expected 30-day mortality (30-DM) to use in audit of radiation oncology departments have been proposed. However, its external validity is limited because of the lack of data from non-English speaking countries. This study assessed 30-DM in patients treated with palliative radiotherapy (PRT) in a Chilean-reference radiotherapy centre and explored if there had been tailored treatment at the end of life.

Materials and methods

Retrospective data collection was carried out for all patients treated at our institution between 1st January 2018 and 31st December 2021. Individual factors were modelled first to check for univariate association with 30-DM, those variables with a significance level of < 0.05 were considered for the final multivariable model.

Results

3,357 patients were included. The most common primary malignancies were breast (22%) and lung (16.1%). The most common treatment sites were bone (47.7%) and brain (12.2%). Overall, 30-DM was 14.7%, this rate was higher in patients treated for brain metastases (25.7%) and thoracic palliation (22.1%). 30-DM was associated with poor performance status (p < 0.01), lung and esophageal-gastric cancer (p = 0.04 and p = 0.02, respectively), metastases other than bone (p < 0.01), brain metastases (p < 0.01) and private health insurance (p <0.01).

Conclusions

In patients treated for brain metastasis and thoracic palliation 30-DM was higher than suggested benchmarks. Moreover, in these groups long courses of PRT were often performed. Audit data should be useful for planning interventions that improve selection of patients and prompting review of policies for indication and fractionation schedules of PRT.

Prognostic Score in Radiotherapy Practice for Palliative Treatments (PROPHET) Study for Bone Metastases: An Investigation Into the Clinical Effect on Treatment Prescription

Purpose

Bone metastases frequently occur during malignant disease. Palliative radiation therapy (PRT) is a crucial part of palliative care because it can relieve pain and improve patients' quality of life. Often, a clinician's survival estimation is too optimistic. Prognostic scores (PSs) can help clinicians tailor PRT indications to avoid over- or undertreatment. Although the PS is supposed to aid radiation oncologists (ROs) in palliative-care scenarios, it is unclear what type of support, and to what extent, could impact daily clinical practice.

Methods and Materials

A national-based investigation of the prescriptive decisions on simulated clinical cases was performed in Italy. Nine clinical cases from real-world clinical practice were selected for this study. Each case description contained complete information regarding the parameters defining the prognosis class according to the PS (in particular, the Mizumoto Prognostic Score, a validated PS available in literature and already applied in some clinical trials). Each case description contained complete information regarding the parameters defining the prognosis class according to the PS. ROs were interviewed through questionnaires, each comprising the same 3 questions per clinical case, asking (1) the prescription after detailing the clinical case features but not the PS prognostic class definition; (2) whether the RO wanted to change the prescription once the PS prognostic class definition was revealed; and (3) in case of a change of the prescription, a new prescriptive option. Three RO categories were defined: dedicated to PRT (RO-d), nondedicated to PRT (RO-nd), and resident in training (IT). Interviewed ROs were distributed among different regions of the country.

Results

Conversion rates, agreements, and prescription trends were investigated. The PS determined a statistically significant 11.12% of prescription conversion among ROs. The conversion was higher for the residents and significantly higher for worse prognostic scenario subgroups, respectively. The PS improved prescriptive agreement among ROs (particularly for worse-prognostic-scenario subgroups). Moreover, PS significantly increased standard prescriptive approaches (particularly for worse-clinical-case presentations).

Conclusions

To the best of our knowledge, the PROPHET study is the first to directly evaluate the potential clinical consequences of the regular application of any PS. According to the Prophet study, a prognostic score should be integrated into the clinical practice of palliative radiation therapy for bone metastasis and training programs in radiation oncology.

Single fraction image guided radiation therapy for management of bone metastases during the COVID-19 pandemic

Aim: Radiation therapy (RT) plays a major role in management of bone metastases, however, various dose-fractionation schemes are utilized taking into account patient, tumor, and treatment characteristics. The aim of this study was to assess Image Guided Single Fraction Radiation Therapy (IG-SFRT) for management of painful bone metastases during the COVID-19 pandemic. Material and Method: Patients receiving IG-SFRT for painful bone metastases were assessed for age, gender, primary cancer diagnosis, location of metastases, performance status, analgesic intake, pain relief, and overall treatment efficacy in this study. Results: Out of the total 65 patients treated with IG-SFRT during the course of COVID-19 pandemic at our department, 54 patients were evaluable for overall treatment efficacy analysis. Based on the international consensus on palliative RT endpoints, rates of complete response (CR), partial response (PR), pain progression (PP), and indeterminate response (IR) were 16.67%, 59.26%, 9.26%, 14.81%, respectively corresponding to an overall response rate of 75.93%. IG-SFRT was well tolerated by all patients without toxicity. Conclusion: For patients with bone metastases, pain palliation is a critical aspect of management. In view of the high rate of overall treatment efficacy achieved with IG-SFRT in our study, we suggest routine utilization of this image guided radiotherapeutic approach for management of painful bone metastases which additionally allows for minimization of treatment visits thereby improving patient and treatment facility convenience under the special circumstances of the recent COVID-19 pandemic.

Do Sustainable Palliative Single Fraction Radiotherapy Practices Proliferate or Perish 2 Years after a Knowledge Translation Campaign?

In early 2017, the Canadian Partnership Against Cancer and CancerCare Manitoba undertook a comprehensive knowledge translation (KT) campaign to improve the utilization of single fraction radiotherapy (SFRT) over multiple fraction radiotherapy (MFRT) for palliative management of bone metastases. The campaign significantly increased short-term SFRT utilization. We assess the time-dependent effects of KT-derived SFRT utilization 12–24 months removed from the KT campaign in a Provincial Cancer Program. This study identified patients receiving palliative radiotherapy for bone metastases in Manitoba in the 2018 calendar year using the provincial radiotherapy database. The proportion of patients treated with SFRT in 2018 was compared to 2017. Logistic regression analyses identified risk factors associated with MFRT receipt. In 2018, 1008 patients received palliative radiotherapy for bone metastasis, of which 63.3% received SFRT, a small overall increase in SFRT use over 2017 (59.1%). However, 41.1% of ROs demonstrated year-over-year decreases in SFRT utilization, indicative of a time-dependent loss of SFRT prescription habits derived from KT. Although SFRT use increased slightly overall in 2018, evidence of compliance fatigue was observed, suggestive of a time-perishing property of RO prescription behaviours derived from KT methodologies. Verification of the study’s findings in larger cohorts would be beneficial. These findings highlight the need for additional longitudinal KT reinforcement practices in the years following KT campaigns.

Radiotherapy of bone metastases

We present the update of the recommendations of the French society of oncological radiotherapy on bone metastases. This is a common treatment in the management of patients with cancer. It is a relatively simple treatment with proven efficacy in reducing pain or managing spinal cord compression. More complex treatments by stereotaxis can be proposed for oligometastatic patients or in case of reirradiation. In this context, increased vigilance should be given to the risks to the spinal cord.

Concurrent capecitabine with external beam radiotherapy versus radiotherapy alone in painful bone metastasis of breast cancer origin

BACKGROUND

In breast cancer, painful bone metastases are common. Local radiotherapy is the standard treatment of painful bone metastases. Pain control and overall response rateswere low in radiotherapy alone.The objectives of this study were to compare the safety and efficacy of external beam radiotherapy with concurrent capecitabine vs. external beam radiotherapy alone in pain control of painful bone metastases in breast cancer patients.

MATERIALS AND METHODS

Eighty-four patients with painful bone metastases from breast cancer participated in this prospective study. We randomized the patients into two groups: group A treated with radiotherapy 30 Gy in 10 fractions and group B treated with capecitabine 825 mg/m2 every 12 hrs. concurrently with the same radiotherapy dose.

RESULTS

There was no statistically significant difference between the two groups regarding early treatment toxicity. Most of the toxicity was gastrointestinal (diarrhea and nausea) and mild (grade I or II). The median pain score decreased from week one, and there was a marked response at week4. The difference in median pain score between both groups was statistically significant with p-value = 0.045. The median analgesic score in both groups was statistically significant with a p-value = 0.032 at week 12. A complete response to pain at week 4 was 19% and 42.9% in groups A and B, respectively.

CONCLUSION

Concurrent chemoradiation in painful bone metastases from breast cancer origin was tolerable and safe; it had a higher overall response rate and pain palliation than radiotherapy alone.

Radiotherapy Practice for Treatment of Bone Metastasis in Ethiopia

PUROSE

Ethiopia has one cobalt radiotherapy (RT) machine to serve a population of more than 100 million. The purpose of this study was to report on patterns of palliative RT of bone metastasis in a severely low-capacity setting.

PATIENTS AND METHODS

Patient and treatment characteristics of patients irradiated for palliation of symptomatic bone metastasis were extracted from a retrospective database of patients treated between May 2015 and January 2018. This database included a random sample of 1,823 of the estimated 4,000 patients who were treated with RT within in the study period. Associations between the applied RT schedule and patient and tumor characteristics were evaluated with the χ² test. Hypothetical savings of RT sessions and time were compared in the case of a single-fraction policy.

RESULTS

From the database, 234 patients (13%) were treated for bone metastasis. Most patients were ≤ 65 years of age (n = 189; 80%) and female (n = 125; 53%). The most common primary sites were breast (n = 82; 35%) and prostate (n = 36; 15%). Fractionated regimens were preferred over single fraction: 20 Gy in 5 fractions (n = 192; 82.1%), 30 Gy in 10 fractions (n = 7; 3%), and 8 Gy in 1 fraction (n = 28; 12%). Factors associated with single-fraction RT included nonaxial sites of bone metastasis (P < .01) and an address outside Addis Ababa (P ≤ .01). If single-fraction RT would have been given uniformly for bone metastasis, this would have resulted in a 78% reduction in the number of RT sessions and 76% reduction in total RT time.

CONCLUSION

The pattern of palliative RT for bone metastasis in Ethiopia favors fractionated regimens over single fraction. Efforts should be made to adopt evidence-based and cost-effective guidelines.

Choosing Wisely Africa: Ten Low-Value or Harmful Practices That Should Be Avoided in Cancer Care

PURPOSE

Choosing Wisely Africa (CWA) builds on Choosing Wisely (CW) in the United States, Canada, and India and aims to identify low-value, unnecessary, or harmful cancer practices that are frequently used on the African continent. The aim of this work was to use physicians and patient advocates to identify a short list of low-value practices that are frequently used in African low- and middle-income countries.

METHODS

The CWA Task Force was convened by the African Organization for Research and Training in Cancer and included representatives from surgical, medical, and radiation oncology, the private and public sectors, and patient advocacy groups. Consensus was built through a modified Delphi process, shortening a long list of practices to a short list, and then to a final list. A voting threshold of ≥ 60% was used to include an individual practice on the short list. A consensus was reached after a series of teleconferences and voting processes.

RESULTS

Of the 10 practices on the final list, one is a new suggestion and 9 are revisions or adaptations of practices from previous CW campaign lists. One item relates to palliative care, 8 concern treatment, and one relates to surveillance.

CONCLUSION

The CWA initiative has identified 10 low-value, common interventions in Africa’s cancer practice. The success of this campaign will be measured by how the recommendations are implemented across sub-Saharan Africa and whether this improves the delivery of high-quality cancer care.

An Intensive Educational Intervention Significantly Improves the Adoption of Single Fractionation Radiotherapy in Uncomplicated Bone Metastases

Introduction:

An education strategy was employed in our department to increase the rate of patients with uncomplicated painful bone metastases undergoing single fractionation radiotherapy (SFRT). The purpose of this report is to analyze the results of this strategy over a 5 year period.

Materials and Methods:

In January 2015, two meetings were organized in our department. In the first, data from an audit on the current SFRT rate were shown. In the second, evidence of SFRT efficacy in the relief of pain from uncomplicated bone metastases was presented. In addition, during the weekly discussion of clinical cases, the opportunity to use the SFRT was systematically recalled. Using our institutional database, all patients treated with radiotherapy for uncomplicated painful bone metastases in the period between 2014 (year considered as a reference) and 2019 were retrieved. Data regarding treatment date (year), radiotherapy fractionation, and tumor, patients, and radiation oncologists characteristics were collected.

Results:

A total of 627 patients were included in the analysis. The rate of patients undergoing SFRT increased from 4.0% in 2014 to 63.5% in 2019 (p < 0.001). At multivariable analysis, the delivery of SFRT was significantly correlated with older patients age (>80 years), lung cancer as the primary tumor, treatment prescribed by a radiation oncologist dedicated to palliative treatments, and treatment date (2014 vs 2015–2019).

Conclusions:

This retrospective single-center analysis showed that a simple but intensive and prolonged departmental education strategy can increase the rate of patients treated with SFRT by nearly 16 times.

National Quality Measure Compliance for Palliative Bone Radiation Among Patients With Metastatic Non-Small Cell Lung Cancer

BACKGROUND

There exists wide practice variability in palliative treatment schedules for bone metastases. In an effort to reduce variation and promote high-quality, cost-conscious care, the National Quality Forum (NQF) endorsed measure 1822 in 2012. This measure recommends the use of 30 Gy in 10 fractions, 24 Gy in 6 fractions, 20 Gy in 5 fractions, or 8 Gy in a single fraction for palliative radiation for bone metastases. We report on longitudinal compliance with this measure.

METHODS

Using the National Cancer Database, patients with metastatic thoracic non-small cell lung cancer diagnosed between 2004 and 2016 who received radiation therapy for bony sites of metastatic disease were identified. Treatment courses fitting 1 of the 4 recommended schedules under NQF 1822 were coded as compliant. Rates of compliance by patient, tumor, and treatment characteristics were analyzed.

RESULTS

A total of 42,685 patients met the criteria for inclusion. Among all patients, 60.2% of treatment courses were compliant according to NQF 1822. Compliance increased over time and was highest for treatments to the extremity (69.8%), lowest for treatments to the skull or head (48.8%), and higher for academic practice (67.1%) compared with community (56.0%) or integrated network facilities (61.2%). On multivariable analysis, predictors of NQF 1822 compliance included year of diagnosis after 2011, treatment to an extremity, or treatment at an academic facility. Of noncompliant treatment courses, extended fractionation (≥11 fractions) occurred in 62.6% and was more common before 2012, in community practice, and for treatments of the skull or head.

CONCLUSIONS

Among patients treated for metastatic non-small cell lung cancer, compliance with NQF 1822 increased over time. Although extended fractionation constituted a majority of noncompliant treatment courses, a substantial proportion also involved shorter courses.

Better pain control with 8-gray single fraction palliative radiotherapy for skeletal metastases: a Bayesian network meta-analysis

External Beam Radiotherapy (EBRT) allows remarkable pain control in patients with skeletal metastases. We performed a Bayesian network meta-analysis comparing the most commonly used radiotherapy regimens for palliative management in patients with skeletal metastases. The main online databases were accessed in October 2020. All randomized clinical trials evaluating the irradiation of painful bone metastases were considered. The following irradiation patterns were analysed and included in the present network meta-analysis: 8 Gy- and 10 Gy/single fraction, 20 Gy/5 fractions, 30 Gy/10 fractions. The Bayesian hierarchical random-effect model analysis was adopted in all comparisons. The Log Odds-Ratio (LOR) statistical method for dichotomic data was adopted for analysis. Data from 3595 patients were analysed. The mean follow-up was 9.5 (1 to 28) months. The cumulative mean age was 63.3 ± 2.9. 40.61% (1461 of 3595 patients) were female. The 8Gy/single fraction protocol detected reduced rate of "no pain response" (LOR 3.39), greater rate of "pain response" (LOR-5.88) and complete pain remission (LOR-7.05) compared to the other dose patterns. The 8Gy group detected a lower rate of pathological fractures (LOR 1.16), spinal cord compression (LOR 1.31) and re-irradiation (LOR 2.97) compared to the other dose patterns. Palliative 8Gy/single fraction radiotherapy for skeletal metastases shows outstanding results in terms of pain control, re-irradiations, pathological fractures and spinal cord compression, with no differences in terms of survivorship compared to the other multiple dose patterns.Level of evidence: I, Bayesian network meta-analysis of RCTs.

Adoption of single fraction radiotherapy for uncomplicated bone metastases in a tertiary centre

•

Single fraction radiotherapy is feasible for uncomplicated bone metastases.

•

Four-week mortality was similar between single fraction and multiple fraction.

•

Our paper has the highest rate of reported single fraction radiotherapy in literature.

•

Re-irradiation were higher for single fraction radiotherapy in uncomplicated bone metastases.

Background

Single-fraction radiotherapy (SFRT) offers equal pain relief for uncomplicated painful bone metastases as compared to multiple-fraction radiotherapy (MFRT). Despite this evidence, the adoption of SFRT has been poor with published rates of SFRT for uncomplicated bone metastases ranging from <10% to 70%. We aimed to evaluate the adoption of SFRT and its evolution over time following the more formal endorsement of the international guidelines in our centre starting from 2013.

Materials and methods

We performed a retrospective review of fractionation schedules at our centre for painful uncomplicated bone metastases from January 2013 until December 2017. Only patients treated with 1 × 8 Gy (SFRT-group) or 10 × 3 Gy (MFRT-group) were included. We excluded other fractionation schedules, primary cancer of the bone and post-operative radiotherapy. Uncomplicated was defined as painful but not associated with impending fracture, existing fracture or existing neurological compression. Temporal trends in SFRT/MFRT usage and overall survival were investigated. We performed a lesion-based patterns of care analysis and a patient-based survival analysis. Mann-Whitney U and Chi-square test were used to assess differences between fractionation schedules and temporal trends in prescription, with Kaplan-Meier estimates used for survival analysis (p-value <0.05 considered significant).

Results

Overall, 352 patients and 594 uncomplicated bone metastases met inclusion criteria. Patient characteristics were comparable between SFRT and MFRT, except for age. Overall, SFRT was used in 92% of all metastases compared to 8% for MFRT. SFRT rates increased throughout the study period from 85% in 2013 to 95% in 2017 (p = 0.06). Re-irradiation rates were higher in patients treated with SFRT (14%) as compared to MFRT (4%) (p = 0.046). Four-week mortality and median overall survival did not differ significantly between SFRT and MFRT (17% vs 18%, p = 0.8 and 25 weeks vs 38 weeks, p = 0.97, respectively).

Conclusions

Adherence to the international guidelines for SFRT for uncomplicated bone metastasis was high and increased over time to 95%, which is the highest reported rate in literature.

Physician-Predicted Prognosis and Palliative Radiotherapy Treatment Utilization at the End of Life: An Audit of a Large Cancer Center Network

CONTEXT

At our institution, clinical pathways capture physicians' prognostication of patients being evaluated for palliative radiotherapy. We hypothesize a low utilization rate of long-course radiotherapy (LCRT) and stereotactic ablative radiotherapy (SAbR) among patients seen at the end of life, especially those with physician-predicted poor prognosis.

OBJECTIVE

To analyze utilization rates and predictors of LCRT and SAbR at the end of life.

METHODS

A retrospective review was conducted on patients who were evaluated for palliative radiotherapy between January 2017 and August 2019 and died within 90 days of consultation. Binary logistic regression was used to identify predictors for utilization of LCRT (≥10 fractions) and SAbR.

RESULTS

A total of 1608 patients were identified, of which 1038 patients (64.6%) were predicted to die within a year. Six hundred ninety-three patients (66.8%) out of 1038 were prescribed LCRT or SAbR. On a multivariate analysis, patients were less likely to be prescribed LCRT if treated at an academic site (odds ratio [OR], 0.30; 95% confidence interval [CI], 0.23-0.39; P < 0.01) and treated for bone metastases (OR, 0.08; 95% CI, 0.05-0.11; P < 0.01) or other nonbrain/nonbone metastases (OR, 0.19; 95% CI, 0.13-0.30; P < 0.01). SAbR was less likely to be prescribed among patients predicted to die within a year (OR, 0.09; 95% CI, 0.06-0.16; P < 0.01), treated for bone metastases (OR, 0.13; 95% CI, 0.07-0.22; P < 0.01), with poor performance status (OR, 0.51; 95% CI, 0.31-0.85; P = 0.01), and with a breast primary (OR, 0.35; 95% CI, 0.15-0.82; P = 0.02).

CONCLUSION

Although most patients were predicted to have a limited prognosis, LCRT and SAbR were commonly prescribed at the end of life.

Bone metastases: a comprehensive review of the literature

The last report of the World Health Organization (WHO) stated that approximately four million people experience bone pain due to malignant diseases. Among them, metastatic bone pain is one of the most important sources of complaint. The estimated median survival in the presence of bone metastases ranks from 10 to 12 weeks. Bone represents a potential target of distant metastases for the majority of malignant tumours. However, the exact incidence of bone metastases is unknown. Bone metastases have an important socio-economic impact, and due to the enhancement of the overall survivorship, their incidence is increasing. Malignant neoplasms such as lung, thyroid, renal cancer, multiple myeloma, and melanoma often metastasize to the bone. Bone metastases commonly localize to the spinal column, pelvis, shoulder, and distal femur. The proper treatment for painful skeletal metastases is still unknown. Hence, the purpose of this review of the literature was to update current evidence concerning the aetiogenesis, biological behaviour, and treatment algorithms for painful skeletal metastases.

Does dissemination of guidelines alone increase the use of palliative single-fraction radiotherapy? Initial report of a longitudinal change management campaign at a provincial cancer program

Background

Despite level 1 evidence demonstrating the equivalence of single-fraction radiotherapy (sfrt) and multiple-fraction radiotherapy (mfrt) for the palliation of painful bone metastases, sfrt remains underused. In 2015, to encourage the sustainable use of palliative radiation oncology resources, CancerCare Manitoba disseminated, to each radiation oncologist in Manitoba, guidelines from Choosing Wisely Canada (cwc) that recommend sfrt. We assessed whether dissemination of the guidelines influenced sfrt use in Manitoba in 2016, and we identified factors associated with mfrt.

Methods

All patients treated with palliative radiotherapy for bone metastasis in Manitoba from 1 January 2016 to 31 December 2016 were identified from the provincial radiotherapy database. Patient, treatment, and disease characteristics were extracted from the electronic medical record and tabulated by fractionation schedule. Univariable and multivariable logistic regression analyses were performed to identify risk factors associated with mfrt.

Results

In 2016, 807 patients (mean age: 70 years; range: 35-96 years) received palliative radiotherapy for bone metastasis, with 69% of the patients having uncomplicated bone metastasis. The most common primary malignancies were prostate (27.1%), lung (20.6%), and breast cancer (15.9%). In 62% of cases, mfrt was used-a proportion that was unchanged from 2015. On multivariable analysis, a gastrointestinal [odds ratio (or): 5.3] or lung primary (or: 3.3), complicated bone metastasis (or: 4.3), and treatment at a subsidiary site (or: 4.4) increased the odds of mfrt use.

Conclusions

Dissemination of cwc recommendations alone did not increase sfrt use by radiation oncologists in 2016. A more comprehensive knowledge translation effort is therefore warranted and is now underway to encourage increased uptake of sfrt in Manitoba.

External validation of life expectancy prognostic models in patients evaluated for palliative radiotherapy at the end-of-life

BACKGROUND

The TEACHH and Chow models were developed to predict life expectancy (LE) in patients evaluated for palliative radiotherapy (PRT). We sought to validate the TEACHH and Chow models in patients who died within 90 days of PRT consultation.

METHODS

A retrospective review was conducted on patients evaluated for PRT from 2017 to 2019 who died within 90 days of consultation. Data were collected for the TEACHH and Chow models; one point was assigned for each adverse factor. TEACHH model included: primary site of disease, ECOG performance status, age, prior palliative chemotherapy courses, hospitalization within the last 3 months, and presence of hepatic metastases; patients with 0-1, 2-4, and 5-6 adverse factors were categorized into groups (A, B, and C). The Chow model included non-breast primary, site of metastases other than bone only, and KPS; patients with 0-1, 2, or 3 adverse factors were categorized into groups (I, II, and III).

RESULTS

A total of 505 patients with a median overall survival of 2.1 months (IQR: 0.7-2.6) were identified. Based on the TEACHH model, 10 (2.0%), 387 (76.6%), and 108 (21.4%) patients were predicted to live >1 year, >3 months to ≤1 year, and ≤3 months, respectively. Utilizing the Chow model, 108 (21.4%), 250 (49.5%), and 147 (29.1%) patients were expected to live 15.0, 6.5, and 2.3 months, respectively.

CONCLUSION

Neither the TEACHH nor Chow model correctly predict prognosis in a patient population with a survival <3 months. A better predictive tool is required to identify patients with short LE.

Oncology Nursing During a Pandemic: Critical Reflections in the Context of COVID-19

OBJECTIVES

To provide a critical reflection of COVID-19 in the context of oncology nursing and provide recommendations for caring for people affected by cancer during this pandemic.

DATA SOURCES

Electronic databases, including CINAHL, MEDLINE, PsychINFO, Scopus, professional web sites, and grey literature were searched using Google Scholar.

CONCLUSION

Nurses are key stakeholders in developing and implementing policies regarding standards of care during the COVID-19 pandemic. This pandemic poses several challenges for oncology services. Oncology nurses are providing a pivotal role in the care and management of the novel COVID-19 in the year landmarked as the International Year of the Nurse.

IMPLICATIONS FOR NURSING PRACTICE

It is too early to tell what shape this pandemic will take and its impact on oncology care. However, several important clinical considerations have been discussed to inform oncology nursing care and practice.

Treatment Options in Oncology

Multiple treatment strategies exist for many oncologic problems. In this review, we provide a summary of various reasons for the existence of multiple treatment options in oncology, including factors that concern the treating physician (eg, treatment preferences), environmental factors (eg, financial, regulatory, and scientific aspects), and individual patient-specific factors (eg, medical condition, preferences). We demonstrate the vital role of available treatment options and their origins for clinical decision making and patient communication. These aspects are particularly helpful in the process of shared decision making, which is increasingly favored in situations where there are multiple medically reasonable options.

Variation in the Use of Single- Versus Multifraction Palliative Radiation Therapy for Bone Metastases in Australia

PURPOSE

To evaluate the use of single-fraction palliative radiation therapy (SFRT) for the management of bone metastases (BM) in Victoria, Australia.

METHODS AND MATERIALS

This is a population-based cohort of patients with cancer who received radiation therapy for BM between 2012 and 2017 as captured in the Victorian Radiotherapy Minimum Data Set. The primary outcome was proportion of SFRT use. The Cochrane-Armitage test for trend was used to evaluate changes in practice over time. Multivariable logistic regression was used to assess factors associated with SFRT use.

RESULTS

Of the 18,158 courses of radiation therapy for BM delivered to a total of 10,956 patients, 17% were SFRT. There was no significant change in SFRT use over time, from 18% in 2012 to 19% in 2017 (P = .07). SFRT was less commonly given to the skull (4%) and spine (14%), compared with the shoulder (37%) and ribs (53%). Patients with lung cancer (21%) were most likely to receive SFRT, followed by those with prostate cancers (18%) and gastrointestinal cancers (16%). Patients from regional/remote areas were more likely to have SFRT compared with those in major cities (22% vs 16%, P < .001). Patients treated in public institutions were more likely to have SFRT compared with those treated in private institutions (22% vs 10%, P < .001). In multivariable analyses, increasing age, lung cancer, higher socioeconomic status, residence in regional/ remote areas, and being treated in public institutions were factors independently associated with increased likelihood of receiving SFRT.

CONCLUSIONS

SFRT appears underused for BM in Australia over time, with variation in practice by patient, tumor, sociodemographic, geographical, and institutional provider factors.

Palliative Radiotherapy Education for Hospice and Palliative Medicine Fellows: A National Needs Assessment

Background: Insufficient knowledge of palliative radiotherapy (PRT) among hospice and palliative medicine (HPM) physicians is thought to be a barrier to the provision of high-quality palliative care. Objective: To assess the need for PRT education in HPM fellowship. Design: A cross-sectional survey of HPM fellows was conducted in June 2018. Setting/Subjects: The survey was distributed to accredited HPM fellowship programs in the United States for distribution to enrolled fellows; 114 fellows responded to the survey. Results: Nearly all respondents agreed that the principles of PRT should be taught in HPM fellowship, yet 51% had received no PRT education and 35% had received only one or two hours. Only 25% of respondents rated their working knowledge of PRT as sufficient, 40% felt confident in identifying radiation oncology emergencies or managing radiotherapy side effects, and 52% felt confident in assessing which patients to refer for radiotherapy. More than 75% agreed that were they more knowledgeable about PRT, they would be more likely to consider referral to radiation oncology, to collaborate with radiation oncologists, and to advocate for a short course of treatment based on a patient's prognosis or goals or care. Fellows who received PRT education in fellowship had significantly greater knowledge of and more favorable attitudes toward the use of radiotherapy. This difference was the greatest among fellows who had received at least five hours of PRT education. Conclusion: There is a need for PRT education in HPM fellowship. Efforts to address this need may lead to more appropriate utilization of PRT for patients with advanced cancer.

Patterns of practice in palliative radiotherapy for bone metastases in UK centres

Background

There is abundant evidence of the comparative efficacy of single-fraction (SF) radiotherapy and multi-fraction (MF) radiotherapy when treating patients with bone metastases. Despite this, previous surveys have shown SF schedules to be underutilised.

Aim

To determine current patterns of practice in patients with bone metastasis and to investigate the factors that influence practice.

Method

An electronic audit was performed amongst 46 physicians, within 7 hospital trusts in the UK. The audit comprised of four hypothetical cases in which consultants and registrars chose which dose and fractionation they would recommend and their reasons for this recommendation.

Results

SF radiotherapy was the most common radiotherapy schedule in hypothetical cases 1, 3 and 4. SF radiotherapy was recommended by 65% of respondents in case 1, 47% in case 2, 89% in case 3 and 46% in case 4. For case 2, 50% proposed MF radiotherapy. For case 4, 22% of respondents recommended Stereotactic Body Radiotherapy (SABR). The following deciding factors were cited as influencing choice of an SF schedule: prognosis, published evidence, performance status and spinal cord compression.

Conclusion

The most common radiotherapy schedule selected was SF. However, there were inter-institution differences regarding the use of SF radiotherapy. Furthermore, the survey had shown that a third of respondents recommended an MF regime, despite evidence supporting the efficacy of an SF schedule.

Automated Survival Prediction in Metastatic Cancer Patients Using High-Dimensional Electronic Medical Record Data

BACKGROUND

Oncologists use patients' life expectancy to guide decisions and may benefit from a tool that accurately predicts prognosis. Existing prognostic models generally use only a few predictor variables. We used an electronic medical record dataset to train a prognostic model for patients with metastatic cancer.

METHODS

The model was trained and tested using 12 588 patients treated for metastatic cancer in the Stanford Health Care system from 2008 to 2017. Data sources included provider note text, labs, vital signs, procedures, medication orders, and diagnosis codes. Patients were divided randomly into a training set used to fit the model coefficients and a test set used to evaluate model performance (80%/20% split). A regularized Cox model with 4126 predictor variables was used. A landmarking approach was used due to the multiple observations per patient, with t0 set to the time of metastatic cancer diagnosis. Performance was also evaluated using 399 palliative radiation courses in test set patients.

RESULTS

The C-index for overall survival was 0.786 in the test set (averaged across landmark times). For palliative radiation courses, the C-index was 0.745 (95% confidence interval [CI] = 0.715 to 0.775) compared with 0.635 (95% CI = 0.601 to 0.669) for a published model using performance status, primary tumor site, and treated site (two-sided P < .001). Our model's predictions were well-calibrated.

CONCLUSIONS

The model showed high predictive performance, which will need to be validated using external data. Because it is fully automated, the model can be used to examine providers' practice patterns and could be deployed in a decision support tool to help improve quality of care.

Palliative radiotherapy near the end of life

Background

A significant proportion of patients with advanced cancer undergo palliative radiotherapy (RT) within their last 30 days of life. This study characterizes palliative RT at our institution and aims to identify patients who may experience limited benefit from RT due to imminent mortality.

Methods

Five hundred and-eighteen patients treated with external beam RT to a site of metastatic disease between 2012 and 2016 were included. Mann-Whitney U and chi-squared tests were used to identify factors associated with RT within 30 days of death (D₃₀RT).

Results

Median age at RT was 63 years (IQR 54–71). Median time from RT to death was 74 days (IQR 33–174). One hundred and twenty-five patients (24%) died within 30 days of RT. D₃₀RT was associated with older age at RT (64 vs. 62 years, p = 0.04), shorter interval since diagnosis (14 vs. 31 months, p <  0.001), liver metastasis (p = 0.02), lower KPS (50 vs. 70, p <  0.001), lower BMI (22 vs. 24, p = 0.001), and inpatient status at consult (56% vs. 26%, p < 0.001). Patients who died within 30 days of RT were less likely to have hospice involved in their care (44% vs. 71%, p = 0.001). D₃₀RT was associated with higher Chow and TEACHH scores at consult (p < 0.001 for both).

Conclusions

Twenty-four percent of patients received palliative RT within 30 days of death. Additional tools are necessary to help physicians identify patients who would benefit from short treatment courses or alternative interventions to maximize quality at the end of life.

Personalized Radiation Therapy in Cancer Pain Management

The majority of advanced cancer patients suffer from pain, which severely deteriorates their quality of life. Apart from analgesics, bisphosphonates, and invasive methods of analgesic treatment (e.g., intraspinal and epidural analgesics or neurolytic blockades), radiation therapy plays an important role in pain alleviation. It is delivered to a growing primary tumour, lymph nodes, or distant metastatic sites, producing pain of various intensity. Currently, different regiments of radiation therapy methods and techniques and various radiation dose fractionations are incorporated into the clinical practice. These include palliative radiation therapy, conventional external beam radiation therapy, as well as modern techniques of intensity modulated radiation therapy, volumetrically modulated arch therapy, stereotactic radiosurgery or stereotactic body radiation therapy, and brachytherapy or radionuclide treatment (e.g., radium-223, strontium-89 for multiple painful osseous metastases). The review describes the possibilities and effectiveness of individual patient-tailored conventional and innovative radiation therapy approaches aiming at pain relief in cancer patients.

Trends in Radiation for Bone Metastasis During a Period of Multiple National Quality Improvement Initiatives

PURPOSE

To evaluate trends in fractionation and cost of radiation for bone metastasis during a time period of multiple national quality improvement initiatives that focused on reducing the number of fractions per radiation episode.

METHODS

Using nationwide Medicare claims from 2011 to 2014, we identified radiation episodes for bone metastasis from prostate, lung, and breast cancer. Details regarding fractionation, radiation therapy (RT) modality, and sociodemographic characteristics were abstracted from claims. Time trends in use of 10 or fewer RT fractions per episode were evaluated using the Cochran-Armitage test. Total cost per episode was calculated from a payer's perspective and reported in 2017 dollars; time trends in cost were assessed using linear regression. Generalized linear models identified predictors of treatment with 10 or fewer fractions.

RESULTS

Of 51,533 episodes identified, 46,326 used 2D/3D RT, 3,199 used intensity-modulated RT, and 2,008 used stereotactic body RT. The proportion of 2D/3D RT episodes using 10 or fewer fractions increased from 65.5% to 79.7% ( P_trend < .001), and mean total cost per episode decreased from $6,742 to $6,067 ( P_trend < .001). Use of single-fraction radiation increased modestly for 2D/3D treatment (6.5% to 8.1%; P_trend < .001). Predictors of 10 or fewer fractions included treatment in recent years, advanced age (≥ 85 years), and higher comorbidity score. Variation was noted based on geographic region and primary cancer.

CONCLUSION

During a period with quality initiatives launched by the American Society for Radiation Oncology, American Board of Internal Medicine, and National Quality Forum, use of 10 or fewer fractions for bone metastasis increased by 14.2%, but single-fraction regimens increased by only 1.6%, highlighting opportunities for quality improvement.

Single versus multifraction radiotherapy for spinal cord compression: A systematic review and meta-analysis

BACKGROUND

While multifraction radiotherapy (RT) regimens (MFRT) have been considered the standard of care in patients with metastatic epidural spinal cord compression (MESCC) with limited prognosis, recent randomized evidence has demonstrated that single fraction RT (SFRT) may be equivalent in terms of functional and overall outcomes. A systematic review and meta-analysis was conducted to determine the effects of SFRT compared to short course MFRT in patients with MESCC.

METHODS

A search of OVID, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to February 2018 was conducted. Randomized and prospective non-randomized trials comparing SFRT and short course MFRT for MESCC were included. Data were analyzed using a random effects model, and relative risks (RR) or hazard ratios (HR) were reported with corresponding 95% confidence intervals (CI). Quality of evidence was assessed using the GRADE criteria.

RESULTS

Overall 1717 articles were reviewed. Three randomized trials were eligible for inclusion (n = 712 patients). The pooled treatment effect for SFRT versus MFRT with respect to motor response was RR = 0.96 (95% CI = 0.86-1.07, I² = 19%), HR = 1.00 (95% CI = 0.88-1.13, I² = 0%) for OS, and RR = 0.97, (95% CI = 0.85-1.11, I² = 61%) for bladder function. There was insufficient data to perform a meta-analysis on quality of life, toxicity or pain response, however available information suggests pain response appears similar between SFRT and MFRT. Overall quality of evidence was deemed moderate due to risk of bias. There was no evidence of an observed difference with respect to motor response, bladder dysfunction and OS between SFRT and MFRT for MESCC in patients with a limited prognosis.

To What Extent Does Radiotherapy Improve the Quality of Life of Patients With Bone Metastasis?: A Prospective, Single-Institutional Study

PURPOSE/OBJECTIVES

Radiation therapy (RT) is an effective method of palliating painful bone metastases and improves the quality of life (QoL) of these patients. The purpose of this trial is 2-fold: to quantify the impact of RT in the QoL of patients with bone metastasis and to compare the QoL results between the most used schemes of RT at our Centre.

MATERIALS AND METHODS

A consecutive sample of patients with bone metastasis treated with RT in the Complejo Hospitalario de Navarra, Spain, was addressed between January 2011 and November 2012. The QoL was measured with the Quality of Life Questionnaire-C15-Palliative questionnaire, a short version of the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire-C30 for palliative care. Two assessments were proposed for each patient: one on the first day of the treatment and the other one a month after the end of the radiotherapy sessions. One hundred and sixteen patients completed the first questionnaire and 75 completed the second one (65%).

RESULTS

Significant differences appeared in 9 domains, with better QoL in the second assessment. Five areas (physical functioning, global, fatigue, nausea, dyspnea, and constipation) showed little change (between 5 and 9 points), 3 (emotional functioning, insomnia, and appetite loss) showed moderate change (10 to 20 points), and 1 (pain) showed a very positive change (>30 points).When we compare the QoL scores between the 2 most used schemes of RT (30 Gy/10 fractions vs. 20 Gy/4 to 5 fractions), there are no significant differences in any QoL areas (and in 2 areas P was near 0.05).

CONCLUSIONS

Palliative RT is a very active treatment for patients with bone metastasis regardless of age, location, primary tumor, or RT scheme. RT significantly improves the QoL, fundamentally by controlling pain and reducing analgesic use. Shorter schemes of RT produce at least-if not better-the same effect on QL than longer schemes (30 Gy).

Are radiation oncologists following guidelines? An audit of practice in patients with uncomplicated bone metastases

•

At our center single fraction radiotherapy is used in accordance with guidelines.

•

Patient age, performance status and tumor histology influence treatment choice.

•

We added a quality indicator to our performance dashboard to improve adherence.

•

This strategy can be used in other complex practices and improve quality of care.

Background

Best-practice guidelines recommend single-fraction (SFRT) instead of multi-fraction radiation therapy (MFRT) for uncomplicated symptomatic bone metastases. SFRT is comparable to MFRT in relieving pain, convenient for patients, and cost-effective. Patterns of practice in Canada reveal that SFRT is underused, with significant variability across the country. We audited SFRT use and studied factors that may influence treatment decisions at a large academic tertiary care center in Quebec, Canada.

Methods

Patients who received radiotherapy for uncomplicated bone metastases between February 2014 and March 2015 were reviewed. Age, gender, primary histology, site of metastases and performance status were identified as potential factors affecting fractionation. These were explored by Fisher's test on univariate analysis and logistic regression for multivariate analysis. Retreatment rates were analyzed with cumulative incidence and compared with Gray's test.

Results

254 radiotherapy courses were administered to 165 patients, 85.4% of which were delivered using a single fraction of 8 Gy. Patients age less than 70 years and those with breast histology were more likely to receive MFRT (p = 0.04; p = 0.0046). Performance status (ECOG) was a significant predictor of fractionation because of high correlations between young age, breast histology, and ECOG status (p = 0.03). Follow-up was too short in 40% of patients to derive definitive conclusions on retreatment.

Conclusions

In accordance with current guidelines, our audit confirms that use of SFRT in patients with uncomplicated bone metastases at our center is high. We identified that patient age, primary histology, and performance status influenced fractionation. Incorporation of this quality indicator into our performance dashboard will allow assessment of retreatment differences and other criteria that may also influence treatment choice.

Patterns of practice in palliative radiotherapy for bleeding tumours in the Netherlands; a survey study among radiation oncologists

•

Current practice in the Netherlands for radiotherapy of bleeding tumours varied considerably.

•

Most often a single fraction of radiotherapy is chosen to treat a bleeding tumour.

•

The choice of radiotherapy schedule is mainly influenced by patient related factors.

Background and purpose

Palliative radiotherapy (RT) is one of the treatment options for bleeding tumours; a frequent symptom in patients with advanced cancer. The optimal RT schedule is however unclear. This study explores the current pattern of practice of palliative RT for bleeding tumours in the Netherlands.

Materials and methods

An internet-based questionnaire, including respondent characteristics, factors influencing the choice of RT schedules and five patient case scenarios, was sent to all members of the Dutch Society for Radiation Oncology. Descriptive statistics were used to evaluate the results.

Results

The response rate was 125/374 (34%); representing 20 out of 21 Dutch RT departments. Most reported influencing factors were performance status, prognosis, patients’ comfort and patients’ choice. Most preferred RT schedules were 1 × 8 Gy for hematemesis, 1 × 8 Gy and 5 × 4 Gy for haemoptysis, 5 × 4 Gy for haematuria, 5 × 5 Gy for rectal bleeding, 1 × 8 Gy, 5 × 4 Gy and 10-13 × 3 Gy for vaginal bleeding.

Conclusions

The current patterns of practice in the Netherlands for bleeding tumours varied considerably. Most often a single fraction is chosen (35% of all cases), followed by a five-fraction schedule (30% of all cases). The choice of an RT schedule is mainly influenced by patient related factors.

Short-course palliative radiation therapy leads to excellent bleeding control: A single centre retrospective study

Purpose

To compare and evaluate the utility of varying hemostatic radiotherapy prescriptions for emergent palliation of bleeding tumors.

Materials and methods

This retrospective study analyzed 112 consecutive patients treated with radiotherapy for emergent palliation of bleeding tumors at an academic institution. Study endpoints included: primary bleeding control; re-bleeding rate after initial control; treatment interruption rate; overall survival; and death within 30 days of treatment.

Results

The most commonly prescribed fractionations were: 20 Gy in 5 fractions, 30 Gy in 10 fractions, and 8 Gy in a single fraction. The overall primary bleeding control rate was 89%. By location, primary bleeding control rates were 89% (31/35), 80% (16/20), 88% (14/16), 93% (13/14), 100% (9/9), and 100% (6/6) for gastrointestinal, genitourinary, head and neck, thoracic, extremity, and gynecologic sites, respectively. The overall re-bleeding rate following initial bleeding control was 25%. Female patients had a significantly reduced risk of bleeding recurrence (HR 0.18 [0.04-0.79], p = 0.02). Longer fractionation regimens (>5 fractions) were not associated with a reduced incidence of re-bleeding (p = 0.65), but were associated with more treatment interruptions (p = 0.02). The 1-year overall survival rate in this population was 24%, with mortality greater in patients with poor performance status (HR 2.99 [1.36-6.58], p = 0.007).

Conclusions

Regardless of prescription, palliative radiotherapy is highly effective for primary bleeding control, with both long and short regimens demonstrating equal hemostatic effect and durability in the emergent setting. Longer radiotherapy regimens (>5 fractions), however, are accompanied by increased treatment interruptions and hospital days. Therefore, shorter hemostatic regimens (<5 fractions) are preferable in this palliative setting, with respect to minimizing treatment burden for patients while achieving symptomatic relief.

Choosing Wisely at the End of Life: Use of Shorter Courses of Palliative Radiation Therapy for Bone Metastasis

PURPOSE

American Society for Radiation Choosing Wisely guidelines recommend ≤10 fractions of radiation therapy (RT) for bone metastasis, with consideration for 1 fraction in patients with a poor prognosis. The purpose of this analysis was to evaluate characteristic differences in guideline concordance to fractionation regimens in a modern cohort of older patients with a diagnosis of bone metastasis.

METHODS AND MATERIALS

Medicare beneficiaries aged ≥65 years treated with RT for bone metastasis from 2012 to 2015 were identified. Guideline-concordant RT fractionation was defined in the entire cohort as ≤10 fractions. Utilization of 1 fraction versus ≥2 fractions was analyzed in deceased patients. Patient demographic, disease, and facility characteristics associated with shorter fractionation were analyzed.

RESULTS

In 569 patients treated with RT, the median age at diagnosis was 73 years. The most common cancer types were lung (37%), genitourinary (26%), breast (15%), and gastrointestinal (10%). Among all patients, 34%, 30%, and 36% received 1 fraction, 2 to 10 fractions, and ≥11 fractions, respectively. In comparison with receipt of 1 to 10 fractions, receipt of ≥11 fractions was associated with a $1467 increase in per-patient cost to Medicare during the calendar quarter of RT. Almost two-thirds of patients who died within 30 days of RT completion were treated with >1 fraction.

CONCLUSIONS

Although guideline concordance was high overall, a large number of patients received longer courses of RT at the end of life. Strong consideration should be made for utilization of shorter courses, particularly in patients with a limited prognosis.

Pain Management in Metastatic Bone Disease: A Literature Review

Cancer means an uncontrolled division of abnormal cells in the body. It is a leading cause of death today. Not only the disease itself but its complications are also adding to the increase in mortality rate. One of the major complications is the pain due to metastasis of cancer. Pain is a complex symptom which has physical, psychological, and emotional impacts that influence the daily activities as well as social life. Pain acts as an alarm sign, telling the body that something is wrong. Pain can manifest in a multitude fashion. Management of bone pain due to metastasis involves different modes with some specific treatments according to the type of primary cancer. Over the years various treatment modalities have been tried and tested to improve the pain management including the use of non-steroidal anti-inflammatory drugs (NSAIDs), opioids, bisphosphonates, tricyclic antidepressants, corticosteroids, growth factors and signaling molecules, ET-1 receptor antagonists, radiotherapy as well as surgical management. The topic of discussion will cover each one of these in detail.

Palliative radiation and fractionation in medicare patients with incurable non-small cell lung cancer

PURPOSE

Palliative radiation therapy (RT) can improve quality of life but also incurs time and financial costs. The aim of this study was to evaluate factors associated with use and intensity of palliative RT for incurable non-small cell lung cancer (NSCLC).

METHODS AND MATERIALS

This was a retrospective analysis of Medicare's Surveillance, Epidemiology and End Results data. We identified patients who were diagnosed with incurable (American Joint Committee on Cancer 6th edition stage IIIB with malignant effusion or stage IV) NSCLC between 2004 and 2011. Univariable and multivariable logistic regressions were used to identify factors associated with the receipt of palliative RT and the use of >10 fractions during the first course of radiation. Among patients who were treated with radiation, freestanding versus hospital-based center information was collected on the basis of the location of the RT delivery claim.

RESULTS

Among 55,258 patients with incurable NSCLC, 38% (21,053 patients) received palliative RT during the first year after diagnosis. Among patients who received RT, 56% (11,717 patients) received >10 fractions. On multivariable analysis, factors associated with greater RT use included younger age group (overall P < .01), lower modified Charlson comorbidity score (overall P < .01), female sex (odds ratio [OR]: 1.1; P < .01), marital status (OR: 1.1; P < .01), and chemotherapy use (OR: 3.6; P < .01). Predictors for >10 fractions were chemotherapy use (OR: 1.7; P < .01) and treatment at a freestanding versus hospital-based facility (58% vs 43%; OR: 1.7; P < .01).

CONCLUSIONS

More than a third of patients diagnosed with incurable lung cancer receive palliative RT and 56% received >10 fractions. The use of RT varied by region and patient characteristics, and patients treated at freestanding RT centers were more likely to receive >10 fractions. Further research into factors that influence treatment decisions including potential financial incentives may contribute to the high value and strategic utilization of palliative RT.

Programmatic Comparison and Dissemination of an Audit of Single-fraction Radiation Therapy Prescribing Practices for Bone Metastases is Associated with a Meaningful and Lasting Change in Practice on a Population Level

PURPOSE

There is ample evidence that single-fraction radiation therapy (SFRT) is as efficacious as more costly and morbid multifraction regimens. We previously demonstrated that an audit-based intervention increased the use of SFRT in all regional cancer centers the following year. However, other investigators have demonstrated that interventions were only associated with a transient 1-year change in prescribing practices. We sought to determine whether our intervention resulted in a more lasting impact.

METHODS AND MATERIALS

In 2012, we performed an audit of the prescribing practices of individual physicians, which was then presented to leaders and oncologists as an intervention to increase SFRT. We compared the use of SFRT between 2007 to 2011 (preintervention) and 2013 to 2016 (postintervention) in all 31,192 patients treated in our provincial program.

RESULTS

The use of SFRT increased from 49.2% to 58.9% postintervention (P < .001). Rates from 2007 to 2011 were 51%, 51%, 48%, 49%, and 48%, respectively, whereas the postintervention rates from 2013 to 2016 were 60%, 62%, 59%, and 56%, respectively. Postintervention, half of the centers prescribed SFRT in a relatively narrow range (55%-58%). However, across all centers, there was still a broad range, with the lowest and highest users at 35% and 81%, respectively, although the lowest-using center still showed a significant increase (26% to 35%; P < .001).

CONCLUSIONS

Our audit and education-based intervention resulted in a lasting and meaningful 10% change in practice. Our provincial rate is similar to that of a previously recommended benchmark rate of 60%, but we continue to see significant variation by center, suggesting further room for improvement in provincial standardization. With emerging evidence in support of ablative radiation therapy for select populations of patients with bone metastases, future benchmark rates of SFRT should be readdressed. However, our data suggest that programmatic comparison and dissemination of SFRT prescribing practices can achieve a population-based SFRT utilization rate near 60%.
