Education, Training and Ongoing Updating for High-Quality Cancer Care: Programs and Technology for Tumor Boards and Case Discussions

Background: The rapid advance in new knowledge of cancer etiology, creation of treatment guidelines, new technologies and medicines into routine practice and the need to understand cost and efficacy that underlie policy are daunting. Remaining current must be accomplished on top of increasingly busy clinical care requirements and patient numbers requires novel solutions. Education and training opportunities are available from professional societies, cancer programs, paid courses and written reviews, though person-to-person mentorship and expert opinion are vital to navigate the vast amount of information. Aim: To provide experience-based insight into addressing the challenge for professionals to maintain one's expertise in cancer care in countries at all income levels. Methods: The International Cancer Expert Corps and partner organizations are establishing a global and multisectoral network that builds human capacity and capability to establish sustainable cancer programs that function at world-class standards ( www.iceccancer.org ). The model utilizes in-person, in-country visits along with ongoing connectivity through telemedicine video conferences. The pioneering education Chartrounds program ( www.chartrounds.com ) is an example of initiative taken by those “in the field” which began in the U.S. and has recently expanded to include separate Web sites for India, Africa, and Latin America. Results: Chartrounds.com, a free Web-based conferencing platform providing disease-site based educational peer review sessions, exemplifies how global expertise can be shared, altruistic education is willingly provided by world-renowned experts and a method of providing practice changing education is possible while the responsibility for the decision-making and treatment implementation remain with the individual treatment center. Weekly experience by Chartrounds and ICEC is defining the complexity of telecommunications, especially problematic with low capacity bandwidth that tests the capacity for effective teleconferences requiring high-quality voice and image data. Conclusion: The enormous body of knowledge needed by cancer practitioners to provide state-of-the-art cancer care requires creative solutions for education, mentorship and telecommunications. That major research institutions such as the National Cancer Institute has invested in developing TELESYNERGY enhances the quality of cancer care and research that are necessary at the global level. Newer platforms are rapidly emerging and artificial intelligence and machine learning will soon assist with education and quality assurance tasks. For UICC members, recognizing present and emerging solutions is critical to best invest in resources and necessary personnel skill-sets to “leapfrog” into the newer enabling technology and approaches to help bring the best possible cancer care into resource-limited environments.

Development and Implementation of a Telemedicine Platform for Radiation Oncology Training and Peer Review

Background: Telemedicine has been posited as a potential means of bolstering radiation therapy delivery in developing nations. World Aid Exchange (WaidX) is an innovative intercontinental telemedicine platform oriented to oncology specialties. This platform, devoted to reducing the digital divide on health practice, provides telecommunication services between health care facilities in developed and developing countries. It conveys the ability to safely share radiologic images and patient medical records for diagnostic and care purposes. It was successfully piloted in Mwanza, Tanzania in 2015. Since then, it has been implemented in varied settings such as Ethiopia, Djibouti and Brazil. After conducting a site visit and a focused needs assessment, we recognized the need for teleconferencing with the Radiation Department of National Center of Oncology, Yerevan, Armenia, to share expertises in general patient management and contouring and planning for radiotherapy. Aim: To develop a TeleRadiotherapy platform that enables: 1: Conference calling for tumor boards to review radiotherapy plans, discuss disease management and conduct remote quality control 2: Real-time sharing of diagnostic images to guide clinical decision making 3: E-contouring activity performed by parties in Yerevan and New York on radiographic images, with minimization of time lag in contouring 4: Generation of a database for clinical data (i.e., radiation dose, toxicity, disease stage) that serves as a departmental registry and a tool for future research use 5: Access to lectures delivered by physicians, nurses, therapists and physicists both in Yerevan and New York on varied aspects of radiotherapy Methods: The initiative was funded through a competitive grant established within the Department of Radiation Oncology at Cornell. The TeleRadiotherapy system is comprised of 2 physical units, equipped to support networking and telephony integration. An application was used to establish a simplified direct connection between mobile phones in New York and fixed phone extensions in Yerevan. A customized version of Veyon was used for remote connection to a contouring station. Zoom was used to establish the teleconference. Remote operators in Weill Cornell Medicine were trained for using the system. Results: The first teleradiotherapy interaction between Yerevan and New York occurred on February 7th, 2018. Demonstration of contouring on the Oncentra treatment planning system in Yerevan revealed ease of use. The brush tool displayed less drag time than the point-by-point contouring tools. Diagnostic images were easily shared without compromise of the image resolution. Conference call quality was high. This conference has opened a series of biweekly chart rounds, between the two institutions. Conclusion: Teleradiotherapy is feasible with excellent voice quality, image sharing capability and real-time contouring. The database is under construction. We are developing a new model for learning, training and collaboration in radiotherapy using WaidX, to enable rapid knowledge and technology transfer for a more equitable access to high-quality cancer care worldwide.

Workforce Capacity and Capability Building Through Metrics-Based Mentoring Partnerships

Background: Globally, cancer is the second leading cause of death. Low- and middle-income countries (LMICs) especially lack the sufficient healthcare and oncology workforces needed to screen, diagnose and treat individuals with cancer. While traditional academic and training programs designed to produce healthcare professionals in these countries fill a critical role, few programs exist that maintain, develop, and increase the knowledge, skills, and professional performance of current healthcare and oncology workforces. Mentoring partnerships and twinning programs can provide ongoing education and training that strengthen and build workforce capacity and capability for the full scope of cancer care. Aim: The goal is to achieve resource-appropriate multimodality cancer-care using guideline- and protocol-based education and training and also to develop the capability to conduct world quality research. The model utilizes in-person, in-country site visits lasting from several weeks to months and ongoing connectivity through weekly telemedicine video conferences. Methods: The International Cancer Expert Corps (ICEC) and partner organizations are establishing a network of global and multisectoral partnerships that builds human capacity and capability needed to establish sustainable cancer programs that function at world-class standards. The three-fold mentor-mentee approach ( www.iceccancer.org ) is built by 1) enlisting hubs of expertise to include academic medical centers/universities, private practices and an ICEC Central Hub, 2) enrolling the breadth of expert-mentors needed from a university, practice, professional society and interested individuals, and 3) identifying centers in LMICs - clinics/hospitals/and other care delivery sites in underserved areas, and associates - physicians/allied healthcare workers- seeking mentoring and education. Results: Recent implementation of the ICEC 5-Step Progression Plan provides guidance and serves as an assessment tool for measuring progress between the hubs-centers programs and expert-associate. Twinning programs (hubs-ICEC centers) have been established in multiple sites worldwide including in Africa, Asia and Eurasia. Conclusion: Implementation of the ICEC 5-Step Progression Plan provides a platform from which to track the current stages and progress of twinning mentor-mentee programs, and to evaluate new programs. This information guides the programs and also provides metric-based investment in global health. Critically as the skills in associates and ICEC centers grows, they achieve expert-mentor status and centers become hubs to serve the surrounding regions, thereby enabling geometric growth in cancer care to meet the needs of the growing global burden of cancer.

The Resource Mothers Study of Maternal Phenylketonuria: preliminary findings

Women with phenylketonuria (PKU) must follow a strict low-phenylalanine diet during pregnancy in order to protect the fetus from the deleterious effects of high maternal blood phenylalanine. The Resource Mothers Study of Maternal PKU was undertaken to determine whether a home visitation programme was effective in helping women with PKU attain blood phenylalanine control earlier during pregnancy. Resource Mothers were trained to provide social support and practical assistance to women with PKU during pregnancy. Eight metabolic clinics in the United States participated in the study. Women with PKU who were planning pregnancy or already pregnant were enrolled in the study and were treated with a low-phenylalanine diet aimed at controlling blood phenylalanine to 120-360 micromol/L. They were randomly assigned to receive the services of a Resource Mother (RM group) or to a control group. Fifty women were enrolled, and accounted for 44 pregnancies which resulted in 28 live births, and 6 spontaneous abortions. Ten women are currently pregnant and another 6 have not become pregnant. Fifty-six percent of enrolled women began the diet prior to becoming pregnant. Fifty-three percent of women in the Resource Mother group were in metabolic control by 10 weeks gestation as compared to 39% in the control group. In addition, women who began diet after pregnancy and had a Resource Mother attained metabolic control earlier (mean gestational age of 22.4 weeks in the RM group vs 29.8 weeks in the control group). There was no difference in birth measurement z -scores of offspring born to women in the RM group compared to controls. All but 4 women rated themselves as feeling worse about the diet at the end of pregnancy than at the beginning, and few women in either group remained on diet after delivery.

The role of calmodulin-binding sites in the regulation of the Drosophila TRPL cation channel expressed in Xenopus laevis oocytes by ca2+, inositol 1,4,5-trisphosphate and GTP-binding proteins

The roles of calmodulin-binding sites in the regulation by Ca2+, inositol 1,4,5-trisphosphate (InsP3) and GTP-binding regulatory proteins (G-proteins) of the Drosophila melanogaster TRPL (transient-receptor-potential-like) non-specific Ca2+ channel were investigated. Wild-type TRPL protein and two mutant forms, TRPL (W713G) and TRPL (W814G), in which a key tryptophan residue in each of the two putative calmodulin-binding sites (Sites 1 and 2, respectively) was replaced by glycine, were expressed heterologously in Xenopus laevis oocytes. Immunofluorescence studies indicated that the expressed TRPL, TRPL (W713G) and TRPL (W814G) proteins are located at the plasma membrane. TRPL oocytes (oocytes injected with trpl cRNA) and TRPL (W814G) oocytes [oocytes injected with trpl (W814G) cRNA] exhibited substantially greater rates of basal (constitutive) Ca2+ inflow (measured using fluo-3 and the Ca2+ add-back protocol) than mock-injected oocytes (mock oocytes). In TRPL (W713G) oocytes, this difference was abolished. In TRPL and TRPL (W814G) [oocytes injected with trpl (W713G) cRNA], but not in TRPL (W713G) oocytes, basal Ca2+ inflow was inhibited by W13, an inhibitor of calmodulin action. Calmodulin (3 muM intracellular) inhibited basal Ca2+ inflow in TRPL but not in TRPL (W713G) or TRPL (W814G) oocytes. Staurosporin, an inhibitor of protein kinase C (PKC), inhibited, while PMA (an activator of PKC) stimulated, basal Ca2+ inflow in TRPL oocytes. In oocytes incubated in the presence of PMA (to suppress Ca2+ inflow through endogenous receptor-activated Ca2+ channels), the InsP3-induced stimulation of Ca2+ inflow through TRPL channels was more clearly evident than in oocytes incubated in the absence of PMA. InsP3 caused a significant stimulation of Mn2+ inflow in TRPL but not in mock oocytes. Rates of InsP3-stimulated Ca2+ inflow through the TRPL, TRPL (W713G) and TRPL (W814G) channels were similar. The ability of GTPgammaS to stimulate Ca2+ inflow through TRPL channels was inhibited by 50% in TRPL (W713G) oocytes but was unaffected in TRPL (W814G) oocytes. It is concluded that, in the environment of the Xenopus oocyte, the Drosophila TRPL channel is activated by (a) interaction with Ca2+/calmodulin at calmodulin-binding Site 1; (b) PKC; (c) InsP3 in a process that does not involve Ca2+ and calmodulin; and (d) a trimeric G-protein(s) through both a Ca2+/calmodulin-dependent and a Ca2+/calmodulin-independent mechanism.

Free-standing cancer centers: rationale for improving cancer care delivery

Free-standing cancer centers (FSCC) represent a growing trend in cancer care delivery within community practice. The critical components to FSCC are multidisciplinary cancer care, a complete menu of direct care and support services, a commitment to clinical trials and clinical investigation, and a comprehensive program for quality assurance. The advantages of FSCC to the community, to hospital programs, to the practicing surgical, medical, and radiation oncologists, and to the third-party carriers, including health maintenance organizations, are detailed. The development of an FSCC depends on the resolution of issues of (a) competition (between hospitals, hospitals and physicians, therapeutic disciplines, regional comprehensive cancer centers and FSCCs) and (b) concerns about conflict of interest. The ideal model of FSCC may well be represented by the joint venture of community hospital(s) and the community oncologists.

Treatment of radiation-induced cystitis with hyperbaric oxygen

The effects of hyperbaric oxygen on radiation cystitis have been documented in 3 patients with radiation-induced hemorrhagic cystitis refractory to conventional therapy. Cessation of gross hematuria and reversal of cystoscopic bladder changes were seen in response to a series of hyperbaric oxygen treatments of 2 atmosphere absolute pressure for 2 hours. To our knowledge this is the first report of cystoscopically documented healing of radiation-induced bladder injury.
