Are you planning to be a radiation oncologist? A survey by the young group of the Italian Association of Radiotherapy and Clinical Oncology (yAIRO)

BACKGROUND AND PURPOSE

The Young Section of the Italian Association of Radiotherapy and Clinical Oncology (yAIRO) circulated an online questionnaire survey among residents currently enrolled within Italian radiotherapy residency schools to investigate the profiles, motivations, knowledge of the radiotherapy discipline, organizations and the needs of younger members.

MATERIALS AND METHODS

The survey was developed by the yAIRO steering committee and included questions about the demographic characteristics of the residents (Profile A), the background of their clinical experience during the school of medicine and national residency admission test performance (Profile B) and the residents' knowledge of the scientific associations active in the field of radiotherapy (Profile C).

RESULTS

Out of 400 residents actually in training, 134 responded to the questionnaire (response rate 33.5%). According to most of the residents, radiotherapy was not adequately studied during the medical school (n. 95; 71%) and an Internship in Radiotherapy was not mandatory (n. 99; 74%). Only a minority of the residents had chosen to complete a master's degree thesis in radiotherapy (n. 12; 9%). A low percentage of the residents stated that they were aware of the Italian Association of Radiotherapy and Clinical Oncology (AIRO), its young section (yAIRO) and the European Society for Radiotherapy and Oncology (ESTRO) when they were in School of Medicine (respectively, 11%, 7% and 13%).

CONCLUSIONS

The results of the survey require a profound reflection on the current teaching methods of Radiation Oncology in our country, highlighting the need for a better integration in the framework of the School of Medicine core curriculum.

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.

Radiation-induced acute toxicities after image-guided intensity-modulated radiotherapy versus three-dimensional conformal radiotherapy for patients with spinal metastases (IRON-1 trial) : First results of a randomized controlled trial

PURPOSE

Radiation therapy (RT) provides an important treatment approach in the palliative care of vertebral metastases, but radiation-induced toxicities in patients with advanced disease and low performance status can have substantial implications for quality of life. Herein, we prospectively compared toxicity profiles of intensity-modulated radiotherapy (IMRT) vs. conventional three-dimensional conformal radiotherapy (3DCRT).

METHODS

This was a prospective randomized monocentric explorative pilot trial to compare radiation-induced toxicity between IMRT and 3DCRT for patients with spinal metastases. A total of 60 patients were randomized between November 2016 and May 2017. In both cohorts, RT was delivered in 10 fractions of 3 Gy each. The primary endpoint was radiation-induced toxicity at 3 months.

RESULTS

Median follow-up was 4.3 months. Two patients suffered from grade 3 acute toxicities in the IMRT arm, along with 1 patient in the 3DCRT group. At 12 weeks after treatment (t2), 1 patient reported grade 3 toxicity in the IMRT arm vs. 4 patients in the 3DCRT group. No grade 4 or 5 adverse events occurred in either group. In the IMRT arm, the most common side effects by the end of irradiation (t1) were grade 1-2 xerostomia and nausea in 8 patients each (29.6%), and dyspnea in 7 patients (25.9%). In the 3DCRT group, the most frequent adverse events (t1) were similar: grade 1-2 xerostomia (n = 10, 35.7%), esophagitis (n = 10, 35.8%), nausea (n = 10, 35.8%), and dyspnea (n = 5, 17.9%).

CONCLUSION

This is the first randomized trial to evaluate radiation-induced toxicities after IMRT versus 3DCRT in patients with vertebral metastases. This trial demonstrated an additional improvement for IMRT in terms of acute side effects, although longer follow-up is required to further ascertain other endpoints.

[Radiotherapy of bone metastases in France: A descriptive monocentric retrospective study]

PURPOSE

Bone metastases cause pain and affect patients' quality of life. Radiation therapy is one of the reference analgesic treatments. The objective of this study was to compare the current practices of a French radiotherapy department for the treatment of uncomplicated bone metastases with data from the literature in order to improve and optimize the management of patients.

MATERIAL AND METHODS

A retrospective monocentric study of patients who underwent palliative irradiation of uncomplicated bone metastases was performed.

RESULTS

Ninety-one patients had 116 treatments of uncomplicated bone metastases between January 2014 and December 2015, including 44 men (48%) and 47 women (52%) with an average age of 63years (25-88years). Primary tumours most commonly found were breast cancer (35%), lung cancer (16%) and prostate cancer (12%). The regimens used were in 29% of cases 30Gy in ten fractions (group 30Gy), in 21% of cases 20Gy in five fractions (group 20Gy), in 22% of cases 8Gy in one fraction (group 8Gy) and in 28% of cases 23.31Gy in three fractions of stereotactic body irradiation (stereotactic group). The general condition of the patient (P<0.001), pain score and analgesic (P<0.001), oligometastatic profile (P=0.003) and practitioner experience (P<0.001) were factors influencing the choice of the regimen irradiation. Age (P=0.46), sex (P=0.14), anticancer treatments (P=0.56), concomitant hospitalization (P=0.14) and the distance between the radiotherapy centre and home (P=0.87) did not influence the decision significantly. A total of three cases of spinal compression and one case of post-therapeutic fracture were observed, occurring between one and 128days and 577days after irradiation, respectively. Eight percent of all irradiated metastases were reirradiated with a delay ranging between 13 and 434days after the first irradiation. The re-irradiation rate was significantly higher after 8Gy (P=0.02). The rate of death was significantly lower in the stereotactic arm (P<0.001) and overall survival was significantly greater in the stereotactic arm (P<0.001).

CONCLUSION

This study showed that patients' analysed was comparable to the population of different studies. Predictive factors for the choice of the treatment regimen were identified. Non-fractionnated therapy was underutilised while stereotactic treatment was increasingly prescribed, showing an evolution in the management of patients.

Prostate cancer as a paradigm of multidisciplinary approach? Highlights from the Italian young radiation oncologist meeting

Aims and background

The diagnostic and therapeutic approach to prostate cancer has evolved rapidly in last decades. Young professionals need an update about these recent developments in order to improve the care of patients treated in their daily clinical practice.

Methods

On May 18, 2013, AIRO Giovani (the young section of the Italian Association of Radiation Oncology) organized a multidisciplinary meeting involving, as speakers, several young physicians from many parts of Italy actively involved in the diagnostic and therapeutic approach to prostate cancer. The meeting was specifically addressed to young physicians (radio-oncologists, urologists, medical oncologists) and presented the state-of-the-art of the diagnostic/therapeutic approach based on the latest evidence on the issue. Highlights of the congress are summarized and presented in this report.

Results

The large participation in the meeting (more than 120 participants were present) confirmed the interest of young radiation oncologists in improving their skills in prostate cancer management. The contributions of the speakers confirmed the need for regular updates, considering the promising results of recently published studies and the many new ongoing trials, on the diagnostic and therapeutic approaches to prostate cancer.

Conclusions

Multidisciplinary meetings are helpful to improve the skills of young professionals.

Review of international patterns of practice for the treatment of painful bone metastases with palliative radiotherapy from 1993 to 2013

BACKGROUND AND PURPOSE

Numerous randomized controlled trials and meta-analyses have affirmed that single and multiple fractions of radiotherapy provide equally efficacious outcomes in the palliation of painful, uncomplicated bone metastases (UBM). We aim to determine geographic, temporal and ancillary factors that influence the global patterns of practice in this setting.

MATERIALS AND METHODS

A literature search was conducted on Ovid MEDLINE and EMBASE. Studies were included if they disclosed prescription patterns of single fraction radiotherapy, either through hypothetical cases or actual patient data. Weighted analysis of variance was conducted for binary predictors while weighted linear regression analysis was performed for continuous parameters.

RESULTS

Nine hypothetical case studies and thirteen actual patterns of practice articles were included from 301 search results. Radiation oncologists prescribed dose fractionations ranging from 3Gy×1 to 2Gy×30, with a median of 3Gy×10, for the palliation of UBM. Actual data demonstrated a weak, non-significant, negative linear relationship between the use of single fraction radiotherapy and the year of treatment. Geographical location of treatment was a key predictor of prescription patterns.

CONCLUSION

In the last twenty years, there was an overall global reluctance to practice evidence-based medicine by employing single fractions for UBM.

The STYRO 2011 project: a survey on perceived quality of training among young Italian radiation oncologists

In order to evaluate the perceived quality of training and education among young Italian radiation oncologists (age <40), AIRO Giovani (Italian Association of Radiation Oncology-Young Members Working Group) carried out a nationwide online survey in 2011, employing a 63-item-based questionnaire, addressed to physician's self-perception of personal training experience (during decade 2001-2011). Issues explored investigated demographics data, duration/organization/content/characteristics of residency programs, the quality of education in clinical oncology, radiation oncology, management and communication attitudes. A total of 382 questionnaires were sent out to physicians and 217 (56.8%) were returned with 197 (51.6%) appropriately filled in and considered for the analysis. The general perception of education and training is positive in most of the explored fields, however some specific contexts and skills still require optimization (combination therapy, peculiar clinical scenarios, particular radiotherapy technical issues, structural organization of residency programs). The present report is expected to be useful for residents, program directors and scientific societies (such as AIRO), to further continue the effort in the improvement of training in radiation oncology.

Continuous controversy about radiation oncologists' choice of treatment regimens for bone metastases: should we blame doctors, cancer-related features, or design of previous clinical studies?

Recent studies from Italy, Japan and Norway have confirmed previous reports, which found that a large variety of palliative radiotherapy regimens are used for painful bone metastases. Routine use of single fraction treatment might or might not be the preferred institutional approach. It is not entirely clear why inter-physician and inter-institution differences continue to persist despite numerous randomized trials, meta-analyses and guidelines, which recommend against more costly and inconvenient multi-fraction regimens delivering total doses of 30 Gy or more in a large number of clinical scenarios. In the present mini-review we discuss the questions of whether doctors are ignoring evidence-based medicine or whether we need additional studies targeting specifically those patient populations where recent surveys identified inconsistent treatment recommendations, e.g. because of challenging disease extent. We identify open questions and provide research suggestions, which might contribute to making radiation oncology practitioners more confident in selecting the right treatment for the right patient.
