RESUMO

We present a case study on the design and implementation of a value-based bundled package of care for patients with early-stage breast cancer treated in the private health sector in Australia. Value-based healthcare is an essential change to how we deliver healthcare, shifting the focus from paying for individual services provided to a focus on the health outcomes gained over a full cycle of care. The Australian health system has unintentionally created barriers to value-based cancer care through fragmented care pathways and complex funding arrangements where patients can unexpectedly encounter high out-of-pocket costs. A team of clinicians, service providers, health systems and funding experts, private health insurers and consumers have collaborated to design and pilot a complete bundled package of care for breast cancer patients which aims to address these challenges. With 40 patients recruited to date, early evaluation results show positive patient experience of 'joined-up' care and financial transparency. This case study provides a high-level overview of the approach taken to design and implement the Breast Cancer Bundle and the lessons learned for its expansion in both public and private settings.

RESUMO

INTRODUCTION: A coronary artery calcium (CAC) CT scan can identify calcified plaque and predict risk of future cardiac events. Cancer survivors undergoing thoracic radiotherapy routinely undergo a planning CT scan, which presents a unique opportunity to use already obtained medical imaging to identify those at the highest risk of cardiac events. While radiation therapy is an important modality for many cancer treatments, radiation dose to the heart in thoracic radiotherapy leads to cardiotoxicity and may accelerate pre-existing atherosclerosis. The primary aims of this study are to investigate the feasibility of using CAC scores calculated on thoracic radiotherapy planning CT scans to identify a subset of cancer survivors at an increased risk of future cardiac events, and to establish and evaluate a referral pathway for assessment and management in a cardio-oncology clinic. An optional substudy aims to investigate using abdominal aortic calcification (AAC) as a practical, low-radiation alternative to CAC to evaluate and monitor vascular health. METHODS AND ANALYSIS: This is an observational, prospective study in a minimum of 100 cancer survivors commencing radiotherapy. Participants will have CAC scored from thoracic radiotherapy planning CT scans. Those identified as high risk (CAC score>0) will be referred to a cardio-oncology clinic. Feasibility, determined by adherence to the recommended pathway, and impact on quality of life and anxiety measured via questionnaire, will be assessed. Participants in Western Australia will be invited to participate in a 12-month observational pilot substudy, investigating lifestyle behaviours and the use of a dual-energy X-ray absorptiometry machine to measure musculoskeletal health and AAC. ETHICS AND DISSEMINATION: Ethics approval has been obtained from St Vincent's Hospital, Sydney (Project number 2021/ETH11847), GenesisCare and Edith Cowan University (2022-03326-DALLAVIA). Study results will be reported in peer-reviewed academic journals, at scientific conferences, and at clinical forums, irrespective of the results observed. TRIAL REGISTRATION NUMBER: ACTRN12621001343897.

RESUMO

PURPOSE: The COVID-19 pandemic has profoundly affected cancer care worldwide, including radiation therapy (RT) for breast cancer (BC), because of risk-based resource allocation. We report the evolution of international breast RT practices during the beginning of the pandemic, focusing on differences in treatment recommendations between countries. MATERIALS AND METHODS: Between July and November 2020, a 58-question survey was distributed to radiation oncologists (ROs) through international professional societies. Changes in RT decision making during the first surge of the pandemic were evaluated across six hypothetical scenarios, including the management of ductal carcinoma in situ (DCIS), early-stage, locally advanced, and metastatic BC. The significance of changes in responses before and during the pandemic was examined using chi-square and McNemar-Bowker tests. RESULTS: One thousand one hundred three ROs from 54 countries completed the survey. Incomplete responses (254) were excluded from the analysis. Most respondents were from the United States (285), Japan (117), Italy (63), Canada (58), and Brazil (56). Twenty-one percent (230) of respondents reported treating at least one patient with BC who was COVID-19-positive. Approximately 60% of respondents reported no change in treatment recommendation during the pandemic, except for patients with metastatic disease, for which 57.7% (636/1,103; P < .0005) changed their palliative practice. Among respondents who noted a change in their recommendation during the first surge of the pandemic, omitting, delaying, and adopting short-course RT were the most frequent changes, with most transitioning to moderate hypofractionation for DCIS and early-stage BC. CONCLUSION: Early in the COVID-19 pandemic, significant changes in global RT practice patterns for BC were introduced. The impact of published results from the FAST FORWARD trial supporting ultrahypofractionation likely confounded the interpretation of the pandemic's independent influence on RT delivery.

RESUMO

BACKGROUND: Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT. METHODS: Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT. RESULTS: Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1-2 resistance training sessions and accumulated 30-40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects. CONCLUSIONS: Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

RESUMO

BACKGROUND: Despite its therapeutic role during cancer treatment, exercise is not routinely integrated into care and implementation efforts are largely absent from the literature. The aim of this study was to evaluate a strategy to integrate the workflow of a co-located exercise clinic into routine care within a private oncology setting in two clinics in the metropolitan region of Western Australia. METHODS: This prospective evaluation utilised a mixed methods approach to summarise lessons learned during the implementation of an integrated exercise workflow and supporting implementation plan. Data collection was informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Reports detailing utilisation of the exercise service and its referral pathways, as well as patient surveys and meeting minutes documenting the implementation process informed the evaluation. RESULTS: The co-located exercise service achieved integration into routine care within the clinical oncology setting. Patient utilisation was near capacity (reach) and 100% of clinicians referred to the service during the 13-month evaluation period (adoption). Moreover, ongoing adaptations were made to improve the program (implementation) and workflows were integrated into standard operating practices at the clinic (maintenance). The workflow performed as intended for ~70% of exercise participants (effectiveness); however, gaps were identified in utilisation of the workflow by both patients and clinicians. CONCLUSION: Integration of exercise into standard oncology care is possible, but it requires the ongoing commitment of multiple stakeholders across an organisation. The integrated workflow and supporting implementation plan greatly improved utilisation of the co-located exercise service, demonstrating the importance of targeted implementation planning. However, challenges regarding workflow fidelity within and across sites limited its success highlighting the complexities inherent in integrating exercise into clinical oncology care in a real-world setting.

RESUMO

PURPOSE: While calls have been made for exercise to become standard practice in oncology, barriers to implementation in real-world settings are not well described. This systematic scoping review aimed to comprehensively describe barriers impeding integration of exercise into routine oncology care within healthcare systems. METHODS: A systematic literature search was conducted across six electronic databases (since 2010) to identify barriers to implementing exercise into real-world settings. An ecological framework was used to classify barriers according to their respective level within the healthcare system. RESULTS: A total of 1,376 results were retrieved; 50 articles describing implementation barriers in real-world exercise oncology settings were reviewed. Two hundred and forty-three barriers were identified across all levels of the healthcare system. Nearly 40% of barriers existed at the organizational level (n = 93). Lack of structures to support exercise integration and absence of staff/resources to facilitate its delivery were the most common issues reported. Despite the frequency of barriers at the organizational level, organizational stakeholders were largely absent from the research. CONCLUSIONS: Implementing exercise into routine cancer care is hindered by a web of interrelated barriers across all levels of the healthcare system. Organizational barriers are central to most issues. Future work should take an interdisciplinary approach to explore best practices for overcoming implementation barriers, with organizations as a central focus. IMPLICATIONS FOR CANCER SURVIVORS: This blueprint of implementation barriers highlights critical issues that need to be overcome to ensure people with cancer have access to the therapeutic benefits of exercise during treatment and beyond.

RESUMO

Bolus serves as a tissue equivalent material that shifts the 95-100% isodose line towards the skin and subcutaneous tissue. The need for bolus for all breast cancer patients planned for postmastectomy radiation therapy (PMRT) has been questioned. The work was initiated by the faculty of the European SocieTy for Radiotherapy & Oncology (ESTRO) breast cancer courses and represents a multidisciplinary international breast cancer expert collaboration to optimize PMRT. Due to the lack of randomised trials evaluating the benefits of bolus, we designed a stepwise project to evaluate the existing evidence about the use of bolus in the setting of PMRT to achieve an international consensus for the indications of bolus in PMRT, based on the Delphi method.

RESUMO

PURPOSE: Post mastectomy radiation therapy (PMRT) reduces locoregional recurrence (LRR) and breast cancer mortality for selected patients. Bolus overcomes the skin-sparing effect of external-beam radiotherapy, ensuring adequate dose to superficial regions at risk of local recurrence (LR). This systematic review summarizes the current evidence regarding the impact of bolus on LR and acute toxicity in the setting of PMRT. RESULTS: 27 studies were included. The use of bolus led to higher rates of acute grade 3 radiation dermatitis (pooled rates of 9.6% with bolus vs. 1.2% without). Pooled crude LR rates from thirteen studies (n = 3756) were similar with (3.5%) and without (3.6%) bolus. CONCLUSIONS: Bolus may be indicated in cases with a high risk of LR in the skin, but seems not to be necessary for all patients. Further work is needed to define the role of bolus in PMRT.

RESUMO

Post-operative radiation therapy (RT) reduces loco-regional recurrence rates and mortality in most patients with non-metastatic breast cancer. The aim of this critical review is to provide an overview of the applicability of moderately hypofractionated RT for breast cancer patients, focusing on factors influencing clinical decision-making. An international group of radiation oncologists agreed to assess, integrate, and interpret the existing evidence into a practical report to guide clinicians in their daily management of breast cancer patients. We conclude that moderately hypofractionated RT to the breast, chest wall (with/without breast reconstruction), and regional lymph nodes is at least as safe and effective as conventionally fractionated regimens and could be considered as the treatment option for the vast majority of the patients.For those who are still concerned about its generalised application, we recommend participating in ongoing trials comparing moderately hypofractionated RT to conventionally fractionated RT for breast cancer patients in some clinical circumstances.

RESUMO

BACKGROUND: Exercise has emerged as a promising therapy for people with cancer. Novel programs have been developed to translate research into practice; however, implementation barriers have limited their success in part because successful translation of exercise oncology research into practice requires context-specific implementation plans. The aim of this study was to employ the implementation mapping protocol to develop an implementation plan to support programming of a co-located exercise clinic and cancer treatment center. METHODS: The Implementation Mapping protocol, which consists of five specific iterative tasks, was used. A stakeholder advisory group advised throughout the process. RESULTS: A comprehensive needs assessment was used to identify the organization's general manager as the program adopter; oncologists, center leaders, and various administrative staff as program implementers; and the operations manager as the program maintainer. Twenty performance objectives were identified. The theoretical domains framework was used to identify likely determinants of change, which informed the selection of eight individual implementation strategies across the individual and organizational levels. Finally, an evaluation plan was developed which will be used to measure the success of the implementation plan in the project's next phase. CONCLUSION: The Implementation Mapping protocol provided a roadmap to guide development of a comprehensive implementation plan that considered all ecological domains, was informed by theory, and demonstrated an extensive understanding of the implementation context. Strong research-practitioner partnerships and effective stakeholder engagement were critical to development of the plan.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the safety, effectiveness, and acceptability of an exercise clinic co-located within a cancer treatment center to identify best practices for integrating exercise medicine into cancer care. DATA SOURCES: Two-hundred thirty-seven patients were referred to the exercise clinic and completed self-report health and demographic questionnaires. Further assessments were conducted at baseline on 67 patients and following completion of the exercise program by 46 patients. Endpoints included muscular strength, physical function, cardiorespiratory fitness, body composition, quality of life, and fatigue scores. Adverse events were tracked throughout exercise participation to evaluate program safety. CONCLUSION: Exercise programming co-located and aligned with cancer treatment in a real-world clinical setting appears to be safe with only four minor exercise-related adverse events. Effectiveness was demonstrated by all physical performance (2.9%-9.5%), strength (7.4%-27.6%), and balance (10.1%) improving and some patients reported outcomes exhibiting modest but clinically relevant benefit. Importantly, no outcomes including fatigue worsened even though the patients were undergoing radiation and/or chemotherapy. Assessment of patient physical and self-reported outcomes should be co-located where they receive oncological treatment and/or exercise medicine to increase uptake of this aspect of the service. Future work should incorporate and describe program and implementation design to help identify best practices in exercise oncology programming. IMPLICATIONS FOR NURSING PRACTICE: Nurses are a primary driver of exercise among patients receiving treatment for cancer. Their regular patient interactions offer a practical opportunity to collect and record important exercise-related information from patients. As organizations look to develop plans to implement exercise into standard practice, input from nurses is critical to ensure program feasibility.

RESUMO

OBJECTIVE: Employ the Reach, Effectiveness, Adoption, Implementation, Maintenance framework to evaluate the effectiveness of a co-located exercise clinic model in increasing access to exercise for people undergoing cancer treatment in a private clinic in Western Australia. METHODS: This retrospective evaluation utilised a mixed-method approach to gather feedback from key stakeholder groups involved with the exercise clinic. Questionnaires and workout summary sheets were gathered from 237 exercise clinic participants over the 50-month evaluation period. These were supplemented by survey results from 119 patients who received cancer treatment at the facility, and semi-structured interviews from seven radiation oncologists, eight nurses, and three accredited exercise physiologists involved with the exercise clinic. RESULTS: The co-located clinic demonstrated positive outcomes related to effectiveness and adoption. Participant feedback indicated satisfaction with the exercise programming (effectiveness), and clinicians were receptive to referring patients to the clinic (adoption). However, no clear implementation or maintenance plan was employed and overall reach (12%) remained suboptimal throughout the evaluation period. CONCLUSION: Co-locating an exercise clinic into a treatment facility does not in itself overcome the logistical challenges of providing integrated exercise services to people during cancer treatment. To enhance its utilisation, an implementation plan needs to accompany the intervention.

RESUMO

OBJECTIVES: The objective of this study was to evaluate patient compliance with management recommendations given by a breast cancer multidisciplinary team (MDT), assess for reasons for noncompliance, and perform an exploratory assessment on breast cancer outcomes in noncompliant patients. MATERIALS AND METHODS: A retrospective analysis of prospectively collected data was undertaken for patients selected by their primary clinician to be discussed at the MDT of Breast Cancer Research Centre-WA in Perth between 1st March 2011 and the 28th February 2016. The primary objective was the rate of compliance with MDT management recommendations. Secondary objectives included factors associated with noncompliance, rate of clinical trial uptake, and impact of treatment noncompliance on breast cancer events in a subgroup of early breast cancer (EBC) patients. RESULTS AND CONCLUSION: A total of 2614 MDT management recommendations were made for 925 patients. Overall, 92% were compliant with all recommendations given. Clinical trial recruitment was successful in 84.1%. The reasons given for treatment noncompliance were fear of toxicity, choosing an alternative treatment, and treatment inconvenience. In a subset of 337 EBC patients, there was a significantly higher rate of contralateral breast cancer, distant recurrence, and breast cancer-specific death, P = .0016, in those who were noncompliant. Our study demonstrates a high rate of MDT treatment recommendation compliance and clinical trial recruitment. In a subgroup of EBC patients, noncompliance was associated with significantly worse outcomes. Attention to educating patients to minimize their fear of treatment toxicity and ensuring their understanding of evidence-based treatment may lead to lower rates of noncompliance.

RESUMO

A study was undertaken to explore the use of volumetric modulated arc therapy (VMAT) for total body irradiation (TBI). Five patient plans were created in Pinnacle3 using nine 6 MV photon dynamic arcs. A dose of 12 Gy in six fractions was prescribed. The planning target volume (PTV) was split into four subsections for the head, chest, abdomen, and pelvis. The head and chest beams were optimized together, followed by the abdomen and pelvis beams. The last stage of the planning process involved turning all beams on and performing a final optimization to achieve a clinically acceptable plan. Beam isocenters were shifted by 3 or 5 mm in the left-right, anterior-posterior, and superior-inferior directions to simulate the effect of setup errors on the dose distribution. Treatment plan verification consisted of ArcCheck measurements compared to calculated doses using a global 3%/3 mm gamma analysis. All five patient plans achieved the planning aim of delivering 12 Gy to at least 90% of the target. The mean dose in the PTV was 12.7 Gy. Mean lung dose was restricted to 8 Gy, and a dose reduction of up to 40% for organs such as the liver and kidneys proved feasible. The VMAT technique was found to be sensitive to patient setup errors particularly in the superior-inferior direction. The dose predicted by the planning system agreed with measured doses and had an average pass rate of 99.2% for all arcs. VMAT was found to be a viable treatment technique for total body irradiation.

RESUMO

INTRODUCTION: This patterns of practice study was conducted on behalf of the RANZCR Breast Interest Group in order to document current radiotherapy practices for breast cancer in Australia and New Zealand. The survey identifies variations and highlights potential contentious aspects of radiotherapy management of breast cancer. METHODS: A fifty-eight question survey was disseminated via the Survey Monkey digital platform to 388 Radiation Oncologists in Australia and New Zealand. RESULTS: In total, 156 responses were received and collated. Areas of notable consensus among respondents included hypofractionation (77.3% of respondents would 'always' or 'sometimes' consider hypofractionation in the management of ductal carcinoma in-situ and 99.3% in early invasive breast cancer); margin status in early breast cancer (73.8% believe a clear inked margin is sufficient and does not require further surgery) and use of bolus in post-mastectomy radiotherapy (PMRT) (91.1% of participants use bolus in PMRT). Areas with a wider degree of variability amongst respondents included regional nodal irradiation and components of radiotherapy planning and delivery (examples include the technique used for delivery of boost and frequency of bolus application for PMRT). CONCLUSION: The results of these patterns of practice survey informs radiation oncologists in Australia and New Zealand of the current clinical practices being implemented by their peers. The survey identifies areas of consensus and contention, the latter of which may lead to a development of research trials and/or educational activities to address these areas of uncertainty.

RESUMO

PURPOSE: Resistance exercise has great potential to aid in the management of breast cancer-related lymphedema (BCRL); however, little is known regarding optimal exercise prescription. The pervasive view is that resistance exercise with heavy loads may be contraindicated, disregarding the dose-response relationship that exists between the load utilised in resistance exercise and the magnitude of structural and functional improvements. No previous research has examined various resistance exercise prescriptions for the management of BCRL. This study compared the effects of high load and low load resistance exercise on the extent of swelling, severity of symptoms, physical function and quality of life in women with BCRL. METHODS: Sixty-two women with a clinical diagnosis of BCRL (>5 % inter-limb discrepancy) were randomly assigned to a high-load resistance exercise (n = 22), low-load resistance exercise (n = 21) or usual care (n = 19) group. Participants in the experimental groups completed a 3-month moderate- to high-intensity resistance exercise program in which the load of the exercises was manipulated from 10-6 repetition maximum (75-85 % of one repetition maximum [1RM]) for the high-load group or from 20-15 repetition maximum (55-65 % 1RM) for the low-load group. Outcome measures included the extent of swelling in the affected arm, symptom severity, physical function and quality of life. RESULTS: There were no differences between groups in the extent of affected arm swelling or severity of symptoms. The change in muscle strength, muscle endurance and quality of life-physical functioning was significantly greater in both high-load and low-load groups compared with the control group (p < 0.040). Change in quality of life-physical function was significantly associated with the change in symptom severity and muscle strength. No lymphedema exacerbations or other adverse events occurred during this trial. CONCLUSION: Women with BCRL can safely lift heavy weights during upper body resistance exercise without fear of lymphedema exacerbation or increased symptom severity. IMPLICATIONS FOR CANCER SURVIVORS: Women with breast cancer-related lymphedema can be informed that appropriately prescribed and supervised upper body resistance exercise is safe and can aid in the management of lymphedema through improvements in physical function and quality of life.

RESUMO

PURPOSE: A previous, unblinded study demonstrated that an alcohol-free barrier film containing an acrylate terpolymer (ATP) was effective in reducing skin reactions compared with a 10% glycerine cream (sorbolene). The different appearances of these products precluded a blinded comparison. To test the acrylate terpolymer principle in a double-blinded manner required the use of an alternative cream formulation, a moisturizing durable barrier cream (MDBC); the study was conducted by the Trans Tasman Radiation Oncology Group (TROG) as protocol 04.01. METHODS AND MATERIALS: A total of 333 patients were randomized; 1 patient was ineligible and 14 patients withdrew or had less than 7 weeks' observations, leaving 318 for analysis. The chest wall was divided into medial and lateral compartments, and patients were randomized to have MDBC applied daily to the medial or lateral compartment and sorbolene to the other compartment. Weekly observations, photographs, and symptom scores (pain and pruritus) were collected to week 12 or resolution of skin reactions if earlier. Skin dose was confirmed by centrally calibrated thermoluminescent dosimeters. RESULTS: Rates of medial and lateral compartment Common Toxicity Criteria (CTC), version 3, greater than or equal to grade 3 skin reactions were 23% and 41%, but rates by skin care product were identical at 32%. There was no significant difference between MDBC and sorbolene in the primary endpoint of peak skin reactions or secondary endpoints of area-under-the-curve skin reaction scores. CONCLUSIONS: The MDBC did not reduce the peak skin reaction compared to sorbolene. It is possible that this is related to the difference in the formulation of the cream compared with the film formulation. Skin dosimetry verification and double blinding are essential for radiation skin care comparative studies.

RESUMO

PURPOSE: To report quality of life (QOL) results for patients receiving chemoradiation therapy for pancreatic cancer. METHODS AND MATERIALS: Eligible patients (n=41 locally advanced, n=22 postsurgery) entered the B9E-AY-S168 study and received 1 cycle of induction gemcitabine (1000 mg/m2 weekly ×3 with 1-week break) followed by 3-dimensional conformal radiation therapy (RT) (54 Gy locally advanced and 45 Gy postsurgery) and concomitant continuous-infusion 5-fluorouracil (5FU) (200 mg/m2/d throughout RT). After 4 weeks, patients received an additional 3 cycles of consolidation gemcitabine chemotherapy. Patients completed the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-PAN26 questionnaires at baseline, before RT/5FU, at end of RT/5FU, before consolidation gemcitabine, and at treatment completion. RESULTS: The patterns of change in global QOL scores differed between groups. In the locally advanced group global QOL scores were +13, +8, +3, and +1 compared with baseline before RT/5FU (P=.008), at end of RT/5FU, before consolidation gemcitabine, and at treatment completion, respectively. In the postsurgery group, global QOL scores were -3, +4, +15, and +17 compared with baseline at the same time points, with a significant improvement in global QOL before consolidation gemcitabine (P=.03). No significant declines in global QOL were reported by either cohort. CONCLUSIONS: This study demonstrates that global QOL and associated function and symptom profiles for pancreatic chemoradiation therapy differ between locally advanced and postsurgery patients, likely owing to differences in underlying disease status. For both groups, the treatment protocol was well tolerated and did not have a negative impact on patients' global QOL.

RESUMO

INTRODUCTION: This study evaluated digital photographs as a method of providing auditable source documentation for radiotherapy-induced skin toxicity and the possibility therefore of centralised, blinded scoring for a multicentre randomised controlled trial. METHODS: Digital photograph sets from the first five patients from each of 12 participating centres were audited. Minimum camera specifications and photograph requirements were protocol specified. Three readers rated photographs for four key quality items. They also scored skin reactions according to National Cancer Institute Common Terminology Criteria (CTC) v3.0 acute skin score and also for the presence of any moist desquamation. RESULTS: Five hundred fifty-two images were available. Field of view was scored as inadequate in 1-10%, focus inadequate in 0.4-4%, lighting inadequate in 0.2-3% and dividing line marking inadequate for scoring of skin reactions within sectors in 18-23% of photographs by three readers. Reader pairwise inter-observer agreement was 83-88% for CTC acute skin scores, but the kappa value ranged from 0.58 to 0.73. The percentage of image sectors not scored by readers due to difficulty in assessing was 1-10%. Moist desquamation was scored by clinicians in 8 (medial)-13% (lateral) of patients compared with 3-5% and 5-11% by readers. CONCLUSION: Photo reader inter-observer agreement is only moderate. Photo readers tended to underscore the frequency of moist desquamation, but the trend by sector parallels the clinical scorers. Photographs are useful source documents for auditing and monitoring, but not a replacement for clinical scoring.
