Bridging the Gap in Global Advanced Radiation Oncology Training: Impact of a Web-Based Open-Access Interactive Three-Dimensional Contouring Atlas on Radiation Oncologist Practice in Russia

Technology-Enhanced Learning in the Education of Oncology Medical Professionals: A Systematic Literature Review

As cancer continues to be a significant global health challenge, the education of oncology professionals plays a crucial role in providing quality cancer care and achieving optimal patient outcomes. In order to meet the growing need for flexible, accessible, and effective training, this study examines the role of technology-enhanced learning (TEL) in the education of oncology medical professionals. Following the PRISMA guidelines, this systematic review included 34 articles published between 2012 and 2022 in EBSCO and PubMed databases. Findings reveal a diverse range of digital tools being used in oncology training, despite a shortage of advanced educational technologies and limited functional improvement compared to traditional instruction. Since the training primarily targeted at multiple professions in the medical expert role, with radiation oncologists being overrepresented, other oncology domains should be examined more thoroughly in the future, taking into account distinct professional abilities, e.g. communication, collaboration, and leadership skills with reference to the CanMEDS framework. Although the training programmes generally resulted in positive outcomes according to the Kirkpatrick evaluation model, experimental research designs were rather limited. Therefore, the substantial contribution and limitations of TEL in oncology education need to be clarified. Precise reporting of digital tools and instructional processes, as well as challenges encountered, is highly recommended to increase transparency and replicability. Research methodology in digital oncology education remains a major concern and should be addressed accordingly in future research.

A cloud-based consultation and collaboration system for radiotherapy: Remote decision support services for community radiotherapy centers

PURPOSE

This study aimed to establish a cloud-based radiotherapy consultation and collaboration system, then investigated the practicability of remote decision support for community radiotherapy centers using the system.

METHODS AND MATERIALS

A cloud-based consultation and collaboration system for radiotherapy, OncoEvidance®, was developed to provide remote services of LINAC modeling, simulation CT data import/export, target volume and organ-at-risk delineation, prescription, and treatment planning. The system was deployed on a hybrid cloud. A federate of public nodes, each corresponding to a medical institution, are managed by a central node where a group of consultants have registered. Users can access the system through network using computing devices. The system has been tested at three community radiotherapy centers. One accelerator was modeled. 12 consultants participated the remote radiotherapy decision support and 77 radiation treatment plans had been evaluated remotely.

RESULTS

All the passing rates of per-beam dose verification are > 94% and all the passing rates of composite beam dose verification are > 99%. The average downloading time for one set of simulation CT data for one patient from Internet was within 1 min under the cloud download bandwidth of 8 Mbps and local network bandwidth of 100 Mbps. The average response time for one consultant to contour target volumes and make prescription was about 24 h. And that for one consultant to design and optimize a IMRT treatment plan was about 36 h. 100% of the remote plans passed the dosimetric criteria and could be imported into the local TPS for further verification.

CONCLUSION

The cloud-based consultation and collaboration system saved the travel time for consultants and provided high quality radiotherapy to patients in community centers. The under-staffed community radiotherapy centers could benefit from the remote system with lower cost and better treatment quality control.

Patterns of Care and Barriers to Utilization of Definitive Concurrent Chemoradiation Therapy for Stage III Non-Small Cell Lung Cancer in Russia

BACKGROUND

Definitive concurrent chemoradiation (cCRT) is offered to only 3% of Russian patients with stage III NSCLC. To determine the patterns of care and barriers to cCRT utilization in Russia, we conducted a survey of practicing radiation oncologists (ROs).

METHODS

Electronic IRB-approved survey containing 15 questions was distributed to Russian ROs. Fisher's exact test or Cochran-Armitage test of trend was used to assess the associations between clinical experience, practice type, and patterns of care.

RESULTS

We analyzed 58 questionnaires completed by ROs-16 respondents from tertiary referral hospitals, and 42 from community or private centers. A total of 88% of respondents formulate treatment recommendations in multi-disciplinary tumor boards. For unresectable stage III NSCLC, the most common recommendation is sequential CRT (50%), followed by concurrent CRT (40%), with an observed higher utilization of cCRT in tertiary centers (9/16, 56% vs 14/42, 33%). Of the respondents, 31% do not offer cCRT to their pts. Among reasons for avoiding cCRT are (1) poor performance of pts (76%); (2) high toxicity of therapy (55%); (3) lack of consensus among tumor board members (33%); and (4) preference for sequential CRT (31%). Only 3% do not irradiate elective LNs. Eighty-six percent of respondents counsel their NSCLC pts regarding smoking cessation.

CONCLUSIONS

Despite level 1 evidence, cCRT is rarely used in Russia for pts with locally advanced NSCLC, and preference for sequential therapy and concerns over high toxicity are the most common barriers. Education of Russian ROs may increase cCRT utilization, leading to improved survival, notably in the era of maintenance immunotherapy.

Education in Radiation Oncology-Current Challenges and Difficulties

The evolution and development of radiotherapy in the last two decades has meant that postgraduate medical training has not kept up with this rapid progress both in terms of multidisciplinary clinical approaches and especially in terms of technological advances. Education in radiation oncology is a major priority in the context of the rapid development of radiotherapy, including advanced knowledge of radiobiology, radiation physics and clinical oncology, anatomy, tumor biology and advanced medical imaging. In this context, the lack of training in radiation oncology in the curricula of medical faculties may have detrimental consequences for the training of residents in radiotherapy but also in their choice of specialty after completing their university studies. There is a clear gap between resident physicians’ actual and required knowledge of radiotherapy, and this requires urgent remediation. In the context of technical advances in imaging-guided radiotherapy (IGRT) and new radiobiology data, a balanced approach divided equally between general oncology, clinical radiation oncology, radiation oncology technology, medical physics and radiobiology, anatomy and multimodal imaging, including mentorship could bring educational and career choice benefits for students of radiation oncology.

Management of Muscle Invasive Bladder Cancer with Bladder Preservation in Russia: a Survey-Based Analysis of Current Practice and the Impact of an Educational Workshop on Clinical Expertise

Trimodality bladder preservation (BP) is an accepted alternative to radical cystectomy for patients with muscle invasive bladder cancer (MIBC). The global utilization of BP is variable, and practice patterns have not been previously studied in Russia. We sought to elucidate the contemporary BP practice patterns in Russia and determine the impact of the BP workshop on attitudes of Russian radiation oncologists (ROs) towards BP. The workshop was focused on patient workup, selection for BP, chemotherapy choices, radiation therapy (RT) contouring and planning, patient counseling. A total of 77 pre- and 32 matched post-workshop IRB-approved surveys, based on the workshop content, were analyzed using descriptive statistics to determine baseline clinical experience and patterns of care. The impact was judged by changes in participants' responses. A total of 56% of respondents had experience with delivering bladder-directed RT, and 60% of those treated both operable and inoperable MIBC patients. Only 10% felt uncomfortable offering an operable patient BP modality. Prior to the workshop, almost half of respondents estimated universal poor bladder (44%) and erectile functions (47%) after BP. The workshop resulted in dramatic change in participants' attitudes towards long-term urinary (Stuart-Maxwell test, p < 0.01) and sexual (exact McNemar test, p < 0.01) side effects. Prior to the workshop, only 47% of respondents routinely discussed smoking cessation (SC) with their patients, whereas after workshop, 88% agreed that SC discussion is mandatory (exact McNemar test, p = 0.04). BP for MIBC is commonly used in Russia. Our workshop resulted in dramatically improved understanding of long-term BP toxicities and inspired Russian ROs to incorporate SC counseling into routine clinical management.

Radiotherapy for Hepatocellular Carcinoma in Russia: a Survey-Based Analysis of Current Practice and the Impact of an Educational Workshop on Clinical Expertise

Radiation therapy (RT) is an effective treatment modality for hepatocellular carcinoma (HCC), but globally, it is underutilized. In Russia, practice patterns with regard to liver-directed radiation are unknown. Under the auspices of Russian Society of Clinical Oncology (RUSSCO), our team conducted an IRB-approved contouring workshop for Russian radiation oncologists. Pre- and post-workshop surveys were analyzed to determine baseline clinical experience and patterns of care for liver-directed RT among Russian providers. The effect of the contouring workshop on participants' knowledge was tested using mixed effects model. Forty pre-workshop and 24 post-workshop questionnaires were analyzable with a 100% response rate. Sixty percent of respondents had never evaluated a patient with HCC and only 8% (3 out of 40) reported treating an HCC patient with liver-directed RT. Nonetheless, 73% of respondents were comfortable offering liver-directed RT prior to the workshop. After the workshop, 85% of respondents felt comfortable treating a patient with HCC with liver-directed RT and 50% were comfortable recommending stereotactic body radiation therapy (SBRT). Measures of knowledge pertaining to evaluation of HCC patients and selection for appropriate liver-directed therapies were dramatically improved after the workshop. Liver-directed RT is not commonly used in Russia in the management of patients with HCC, and few centers are equipped for motion management. Our contouring workshop resulted in dramatically improved understanding of the evaluation and management of HCC patients. We recommend starting with a more protracted fractionated RT and building experience through attendance of additional educational activities, participation in multidisciplinary liver tumor boards, and prospective analysis of treatment toxicity and outcomes.

Development and Usage of eContour, a Novel, Three-Dimensional, Image-Based Web Site to Facilitate Access to Contouring Guidelines at the Point of Care

PURPOSE

Variation in contouring quality by radiation oncologists is common and can have significant clinical consequences. Image-based guidelines can improve contour accuracy but are underused. We sought to develop a free, online, easily accessible contouring resource that allows users to scroll through cases with 3-dimensional images and access relevant evidence-based contouring information.

MATERIALS AND METHODS

eContour (http://econtour.org) was developed using modern Web technologies, primarily HTML5, Python, and JavaScript, to display JPEGs generated from DICOM files from real patient cases. The viewer has standard tools for image manipulation as well as toggling of contours and overlayed images and radiation dose distributions. Brief written content references published guidelines for contour delineation. Mixpanel software was used to collect Web page usage statistics.

RESULTS

In the first 3 years of operation (March 8, 2016 to March 7, 2019), a total of 13,391 users from 128 countries registered on the Web site, including 2,358 physicians from the United States. High-frequency users were more likely to be physicians (P < .001) and from the United States (P < .001). In one 6-month period, there were 68,642 individual case page views, with head-and-neck the most commonly viewed disease site (32%). Users who accessed a head-and-neck case were more likely to be high-frequency users, and 67% of repeat users accessed the same case more than once.

CONCLUSION

The large, diverse user base and steady growth in Web site traffic over the first 3 years of eContour demonstrate its strong potential to address the unmet need for dissemination and use of evidence-based contouring information at the point of care.
