Abstract B007: A qualitative research study on hematology and oncology consultants’ experiences and opinions on using minimal residual disease (MRD) as a fast-track approval endpoint in early-phase clinical trials in multiple myeloma in Saudi Arabia

Abstract Introduction: The U.S. Food and Drug Administration recently considered the minimal residual disease (MRD) as an acceptable accelerated approval endpoint in multiple myeloma (MM). The data from the meta-analysis studies established the clinical benefit of MRD negativity in certain hematological cancers such as MM. Objectives: The primary objective of this qualitative research study is to assess hematology and oncology consultants’ opinions and experiences on the adequacy of using minimal residual disease (MRD) as an intermediate endpoint in early- phase clinical trials in multiple myeloma (MM) for fast-track approval of drugs and biological products in the Saudi Food and Drug Authority. That may include using MRD in MM in both settings: newly diagnosed and relapsed/refractory MM. The secondary objective is to gather information about the feasibility and availability of sensitive methods for detecting MRD in the context of real-world medical practice and clinical trials in Saudi Arabia. Study Design: The study design is a qualitative approach to interviewing 30 registered male, or female physicians specialized in hematology and oncology in Saudi Arabia. The interviews will be conducted in two ways: a single focus group and several face-to-face interviews. The participants should have more than 1 year of experience post-fellowship training. The participants will be invited for an interview via email or phone. A predetermined set of semi-structured questions is to be asked in the same order to each participant. The topic of questions will include the definition of MRD, clinical and research significance of MRD, MRD detection thresholds (e.g., 10^-5 vs. 10^-6), duration of MRD negativity at the complete response, correlation with other clinical endpoints such as progression-free survival (PFS) and overall survival (OS). The interviews will be conducted by scientific oncology and hematology evaluation experts at the Saudi Food and Drug Authority who have considerable experience in engaging in personal discussion. This qualitative study has about 5–10 semi-structured one-to-one interviews of hematology and oncology consultants performed at a convenient time for each doctor. Moreover, the discussions in focus groups can be as small as four participants. Qualitative data will be prepared and analyzed by an expert in data analysis.

Abstract B006: Qualitative research study on the use of minimal residual disease as an intermediate endpoint in multiple myeloma clinical trials in Saudi Arabia

Abstract Introduction: The U.S. Food and Drug Administration has recently considered minimal residual disease (MRD) as an acceptable accelerated approval endpoint in multiple myeloma (MM). Meta-analysis studies have shown the clinical benefit of MRD negativity in certain hematological cancers such as MM. Objectives: This qualitative research study, with a unique focus on the Saudi context, aims to assess the opinions and experiences of hematology and oncology specialists and consultants in Saudi Arabia. The study is particularly interested in their views on the use of MRD as an intermediate endpoint in early-phase clinical trials for fast-track drug approval by the Saudi Food and Drug Authority in the context of multiple myeloma. This includes assessing the use of MRD in both newly diagnosed and relapsed/refractory MM. The secondary objective is to gather information about the feasibility and availability of sensitive MRD detection methods in real-world medical practice and clinical trials in Saudi Arabia. Study Design: The study will involve interviewing 30 registered male or female physicians specialized in hematology and oncology in Saudi Arabia. The physicians will be included in the study using purposive sampling methods. The study will collect the physicians’ opinions and experiences about MRD. The interviews will be conducted through a single focus group and several face-to- face interviews or performed online, using ZOOM. Participants should have more than one year of experience post-residency or post-fellowship training. The predetermined set of semi- structured questions will cover topics such as the definition of MRD, its clinical and research significance, MRD detection thresholds, duration of MRD negativity, and its correlation with other clinical endpoints, such as progression-free survival and overall survival. The interviews will be conducted by scientific oncology and hematology evaluation experts at the Saudi Food and Drug Authority, who play a crucial role in this study. The study will consist of 5–10 semi- structured one-to-one interviews and focused group discussions of as few as four participants. Before starting any interview, participants will complete consent forms, including the study’s goals and who will conduct the study. Qualitative data will be prepared and analyzed by an expert in data analysis, ensuring the highest research standards. The results will be presented using descriptive and interpretive methods.

Kidney-Sparing Management of UTUC in Solitary Kidney Patients: A Retrospective Analysis and Narrative Review

Background/Objectives: The aim of this study is the presentation of an endoscopic therapeutic approach for three patients with a solitary kidney who were diagnosed with urothelial cancer of the upper tract. Methods: This retrospective analysis included patients with solitary kidneys who suffered from high-grade UTUC (urothelial cancer of the upper urinary tract) and underwent conservative treatment. Results: The first patient was a 67-year-old male who had a prior history of a nephroureterectomy due to UTUC six years ago. The patient was diagnosed with high-grade UTUC in the contralateral kidney. The tumor has been managed with endoscopic ablation. The second patient was a 74-year-old male with a non-functional kidney and high-grade UTUC diagnosed in the contralateral side. The patient underwent endoscopic ablation for the tumor. The third case was a 68-year-old female patient who had a history of a nephroureterectomy due to UTUC. Afterward, she was diagnosed with high-grade UTUC in the contralateral kidney. The patient was treated with percutaneous tumor resection and the placement of a nephrostomy tube. The first patient was included in an immunotherapy program based on an oncologist consultation after laser ablation treatment for Ta high-grade UTUC, followed by the endoscopic management of two recurrences. Afterward, no recurrence was detected. The remaining two patients followed up without the detection of a new recurrence. Conclusions: The kidney-sparing approach (tumor laser ablation or resection) for high-risk UTUC treatment in selected patients with solitary kidneys seems to provide adequate early outcomes in relation to preserving renal function and effective disease management. It is important to personalize the way of treatment in every case after a thorough examination of the patient’s data.

Impact of Surgeon-Radiation Oncology Dyads in Oral Cavity Cancer Outcomes.

Multidisciplinary care is paramount in patient-specific decision making, especially as pertaining to oral cavity squamous cell cancer (OCSCC) treatment. Protracted surgery-postoperative-radiation (S-PORT) has a detrimental impact on OCSCC patients' outcomes. This study examined the impact of surgeon-radiation oncologist dyads on the treatment of OCSCC, focusing on S-PORT interval and disease specific outcomes. All OCSCC patients treated in a tertiary cancer center between 2009 to 2017 were included. Patients were categorized into "dyad" and "nondyad" groups defined as whether they were treated by a paired surgeon-radiation oncology team with joint multidisciplinary clinic or shared >30% patient volumes. Univariate and multivariate logistic regression were performed to identify factors associated with a prolonged S-PORT time interval (≥8 weeks). Overall survival and locoregional recurrence were estimated and compared. A total of 444 OCSCC were eligible. Treatment by a dyad was significantly less likely associated with S-PORT ≥ 8 weeks (odds ratio [OR]unadjusted: 0.65; 95% confidence interval [CI] 0.44-0.96; p = 0.03). Obtaining pre-operative radiation oncology consultation also decreased the S-PORT interval. Advanced T-category and the need for free tissue flap reconstruction increased the likelihood of prolonged S-PORT on univariate but not multivariate analysis. No significant differences were observed in overall survival or locoregional recurrence by dyad status nor S-PORT (p > 0.05). Surgeon-radiation oncology dyads significantly minimized time from surgery to postoperative radiation in OCSCC. While improvement in overall survival or locoregional recurrence was not observed, these findings support close knit collaborative multidisciplinary treatment care models, including dyad-based care.

A Multicenter Physician Survey Evaluating the Use of Ki-67 in Breast Cancer Management in Canada

Background: Ki-67’s response to pre-operative endocrine therapy (ET) in early breast cancer is an evidence-based tool to guide adjuvant treatment decisions. Physicians across Canada were surveyed to explore current practice patterns and perceived barriers to the use of Ki-67 in practice. Methods: Physicians were invited to participate in an anonymous survey and were eligible if they prescribed systemic therapy for breast cancer in Canada. Respondents were asked to describe their usage of Ki-67, perceptions of the evidence surrounding Ki-67 ET response, and interest in future trials using this approach. Results: The survey received 48/163 responses (29.4%). The majority of respondents (97.6%) reported access to Ki-67 testing upon request. Treatment decisions for adjuvant Abemaciclib was the most common reason (97.6%), followed by adjuvant chemotherapy decisions (16.7%). Only 19.0% had used Ki-67’s response to pre-operative ET in practice. Common barriers to this approach that were identified included a lack of awareness from other providers (54.8%), an increased resource requirement (54.8%), and a lack of timely medical oncology consultation (52.4%). The majority of physicians (85.3%) reported that they would participate in future trials using the Ki-67 endocrine response, and that rate of treatment decision change (95.2%) and cost analysis (42.3%) were important endpoints. Conclusions: Despite the widespread availability of Ki-67 testing, few physicians in Canada currently use it to assess endocrine response, predominantly due to logistical and resource constraints. There is a high level of interest in participating in future trials using this strategy, which should focus on disease related outcomes, feasibility, and the financial impact on the public healthcare system.

Multiple Myeloma Presenting with Severe Back Pain: A Case Report

This study aims to highlight the diagnostic challenges and management strategies in a case of Multiple Myeloma (MM), a hematologic malignancy characterized by malignant plasma cells in the bone marrow. The case involves a 40-year-old male who presented with persistent back pain for two months, impacting his mobility. Initial physical and neurological assessments were largely unremarkable, but laboratory and radiological investigations revealed multiple osteolytic lesions suggestive of MM. Typical MM symptoms include hypercalcemia, renal dysfunction, anemia, and bone pain, though this patient did not present all the classical signs, which underscores the diagnostic complexity. A bone marrow puncture was planned for definitive diagnosis. The study emphasizes the importance of radiological evaluation in MM diagnosis and the need for prompt treatment addressing acute symptoms, such as hypercalcemia and renal insufficiency, followed by a comprehensive long-term management plan. Early oncology consultation and a multidisciplinary approach are critical for improving patient outcomes. The case demonstrates the importance of a holistic, symptom-based approach in MM management, incorporating regular monitoring and coordinated care to address the multifaceted nature of the disease.

Communication and information about complementary medicine in a Dutch oncology setting: Interviewing patients and providers on their experiences and needs

BackgroundComplementary medicine such as yoga, massage and art therapy has become increasingly popular among patients with cancer. However, the topic remains under-discussed during oncology consultations: patients seem hesitant to disclose complementary medicine use, and healthcare providers lack resources to discuss complementary medicine. This study aims to gain an understanding of how to improve communication and information provision in oncological settings about complementary medicine by assessing the experiences and needs of patients and healthcare providers. Materials and methodsSemi-structured interviews were conducted with 17 patients with cancer and 13 oncology healthcare providers recruited from two general hospitals and one breast cancer center in the Netherlands. Nine (former) patients with breast cancer collaborated with the research team as ‘co-researchers’. Reflexive thematic analysis was used. ResultsThe main themes identified were barriers to patient-provider communication about complementary medicine (e.g. lack of time and knowledge among healthcare providers, negative attitudes toward complementary medicine), facilitators of communication (e.g. openness of healthcare providers, complementary medicine as a routine topic) and information provision needs (e.g. easy access to information, the hospital being involved in providing information). ConclusionPatients with cancer and healthcare providers report issues with the current approach to discussing complementary medicine and are of the opinion that complementary medicine should be a routine topic in oncology consultations. Future studies should focus on effective methods for standardizing complementary medicine discussions into oncology care and making reliable information available for patients and healthcare providers.

8062 Uncommon Presentation of Multiple Myeloma as a Rapidly Growing Thyroid Goiter Initially Thought to be Hashimoto's Thyroiditis

Abstract Disclosure: M.S. Shah: None. S. Humayon: None. K.P. Sanu: None. C. Peñaherrera: None. We present a unique case of an 85-year-old female with rapidly growing anterior neck swelling and subclinical hyperthyroidism, initially suggestive of Hashimoto's thyroiditis. The goiter initially responded well to steroids but rebounded back in size despite two courses of prednisone. This prompted further diagnostic workup which revealed unexpected findings, ultimately leading to the diagnosis of multiple myeloma involving the thyroid parenchyma and lymph nodes. The patient had no history of thyroid disorders or recent upper respiratory tract infections. She exhibited sudden neck swelling, mild subclinical hyperthyroidism, and positive TPO antibodies. Initial fine needle aspiration suggested lymphoid tissue with Hurthle cell differentiation, raising suspicion of Hashimoto's thyroiditis. Flow cytometry supported this diagnosis, but the potential for a Hurthle cell neoplasm persisted. Prednisone temporarily reduced thyroid size, but disease recurrence necessitated surgical excisional and incisional biopsies. Subsequent biopsies revealed plasma cell neoplasms consistent with multiple myeloma. The pathologic report confirmed MYC rearrangement, indicative of multiple myeloma involvement in lymph nodes and thyroid tissue. Protein electrophoresis revealed two restricted bands migrating in the gamma globin region. The patient experienced subclinical hyperthyroidism that evolved into euthyroidism over a month. Incidental findings included non-invasive, low grade papillary urothelial carcinoma. Disease progression was evident in a follow-up PET/CT, prompting oncology consultation. The patient initiated Revlimid with chemotherapy. Levothyroxine was prescribed for postoperative hypothyroidism, with adjustments based on thyroid panel results. This case report illustrates the intricate diagnostic challenges posed by multiple myeloma masquerading as a thyroid disorder. The unexpected evolution of the disease, marked by MYC rearrangement and metastatic spread, emphasizes the need for heightened vigilance in managing such cases. Clinicians should consider alternative diagnoses when treatment efforts fail to provide adequate response. This will ensure timely and appropriate management in clinical practice. This report contributes valuable insights into the diagnostic complexities and multidisciplinary considerations for addressing similar presentations in endocrine and oncology settings.

Time from Diagnostic Suspicion to In-Person Evaluation in Skin Cancer Using Teledermatology.

Introduction: Early diagnosis of skin cancer is crucial for improving prognosis. Teledermatology (TD) usage can optimize referrals and reduce waiting times. This study aims to evaluate waiting times at the critical referral nodes in teleinterconsultations that raised suspicion of skin malignancy in the Chilean TD platform of the public health care system. Materials and Methods: A cross-sectional observational study that analyzed asynchronous teleinterconsultations and raised suspicion for skin malignancy following the teledermatologist evaluation was uploaded on the Chilean Ministry of Health's TD platform from January 1 to June 30, 2022. Results: Out of 20,522 teleinterconsultations, 1,853 raised suspicion of skin cancer. Among them, 1,119 patients were assessed by in-person examination, while 669 were still on the waiting list. Response times averaged 3.98 days for TD diagnostic suggestions. Overall referral times averaged 75.98 days from initial teleinterconsultation to the final specialist in-person evaluation. Waiting times showed significant differences among health care services and geographic regions. Discussion: In resource-limited settings, TD serves as a valuable tool to optimize referrals and manage the demand for oncologic dermatological consultation. The long waiting times emphasize the need for targeted interventions, especially in regions with longer delays. Conclusion: While TD has shown to be an effective tool in optimizing referrals, waiting times still exceed international recommendations, even in urban centers. The considerable heterogeneity in referral times within health care services and geographic regions highlights the necessity of establishing standardized referral protocols and explicit deadlines to fulfill teleinterconsultations that raise suspicion of skin malignancy in the Chilean public system.

General versus disease-specific medical oncology consults and impact on inpatient quality of care.

321 Background: Hospitalization is a time of crisis for patients and caregivers. Subspeciality oncologists may bring more timely, effective support compared to a general oncologists. Attendings, fellows and advance practice providers (APPs) may benefit from focused expertise for consultative care and education. Methods: Subspeciality oncology consults launched July 2023, with consults staffed by 4 oncologists from: 1) breast 2) head and neck/thoracic 3) gastrointestinal and 4) genitourinary/melanoma. Previously, 3 oncologists staffed all patients, regardless of primary malignancy. Throughout the study period, oncologists were supported by at least 1 fellow or 1 APP. Using Epic and Tableau, we collected LOS, time to consult (TTC), ICU rate, hospice referral rate, 30-day readmission, 30-day emergency department (ED) visit data. Using Qualtrics, we collected fellow, attending, and APP satisfaction feedback pre- and post-intervention. Data was analyzed using R-4.40. Oncologists, fellows, and APPs completed Qualtrics surveys pre- and post-intervention regarding their experience. Results: Subspeciality oncology consults were associated with a significant decrease in LOS, TTC, and ICU rate. Median LOS decreased by 2.0 days (P<0.001), with median TTC decreasing by 1.0 hour (P=0.003). ICU rate decreased from 27.5% to 16.4% (P<0.001). There was no difference in hospice referrals or 30-day ED visits. A significant increase in 30-day readmission during post-intervention was observed (Table). Oncologists reported a high level of satisfaction with the program. Oncologist, fellow, and APP overall experience and educational rankings increased after the introduction of subspeciality consults. Inpatient productivity measured by wRVU increased by 30% following the intervention, without associated changes to outpatient productivity. Conclusions: Transition to a subspeciality oncology consult model improved inpatient quality of care, as well as clinician experience. Additionally, inpatient productivity increased without decrease in outpatient metrics. Subspeciality medical oncology consultation can improve inpatient quality of care, education, clinician satisfaction and productivity. Subspeciality oncology consult outcomes.

Association between genetic information provision and decisional conflict in patients with cancer.

227 Background: The decisional conflict scale (DCS) measures personal perception of uncertainty when facing a decision. In patients with cancer, decision conflict is likely when considering uncertainty in oncologic systemic treatment outcomes. Cancer genomic information can introduce more uncertainty and complexity in care. This study aims to evaluate patients’ DCS score pre or post discussing next generation sequencing (NGS) results with a medical oncologist, and assess factors that correlate with high decision conflict. Methods: Patients diagnosed with incurable/metastatic cancer who underwent molecular characterization with tissue+/- liquid NGS testing were enrolled. Survey instruments included the validated DCS (five subscales: informed, values clarity, support, uncertainty, effective decision), and EQ-5D-5L. DCS was administered pre or post medical oncology consultation that included review of tissue +/- liquid NGS results and treatment options. Higher DCS score correlates with higher perception of uncertainty. Descriptive statistics were used to assess clinical and demographic risk factors. Multivariable logistic regression analysis estimated the correlation between high DCS and clinical factors. Results: 335 DCS surveys were completed by 227 patients: 188 before and 147 after discussing tissue+/- liquid NGS results with a medical oncologist. Baseline characteristics: 56% female, median age 65, ECOG 0-1 58%, median EQ5D VAS score 68, GI/lung/gyne/breast/other 42/32/10/5/11%, white/Asian/other/unknown 66/12/5/17%. Tier 1 variants were identified in 35% of patients. Patients reported decreased decision conflict after consultation. Multivariable logistic regression analysis including sex, age, race and tumor group did not predict for high DCS pre-consultation. MVA post NGS results that also included Tier 1 variants (present / absent) did not predict for high DSC post consultation. Conclusions: Communication regarding genomic-based tumor assessment can positively support patients in decision conflict, and improve their confidence in their treatment choice, regardless of the findings of the report. Low DCS after consultation supports the goal of shared decision making for cancer treatment. Clinical trial information: NCT05057234 .

Improving distress screening in radiation oncology consultation.

332 Background: Receiving a cancer diagnosis and awaiting initial management recommendations is a stressful time. Distress should be recognized, documented, and treated promptly as part of quality oncologic care. The NCCN Distress Thermometer (DT) is a useful tool for patients to quantify their level of distress. This pilot study assesses the rate of distress screening at a high-volume academic healthcare network, before and after institutional quality improvement (QI) intervention. Methods: All patients seen for Radiation Medicine between 1/1/22 - 12/31/23 were reviewed. Rates of DT documentation at the time of consultation were assessed as the QI metric. Patients seen in 2022 served as a baseline of departmental compliance. The importance of distress assessment was formally introduced to physicians and advanced care practitioners (ACPs) in Q4 2022 during monthly departmental quality reports, with notice that a formal QI metric would be monitored beginning 1/1/23. Chi-square test was used to compare rates of DT documentation. Monthly departmental DT documentation rates were back presented to the physicians and ACPs during quality meetings. Results: 9391 patients were seen for radiation oncology consultation (2022 = 4311; 2023 = 5080). Baseline DT documentation was 51.0%. Initial compliance with the metric was below baseline, at 41.4% for Jan 2023. With continued feedback, education, and goal-setting, rates of DT use continually improved over Q1/Q2 2023 and remained relatively steady through the remainder of Q3/Q4 2023, reaching a monthly high of 89.8%. Overall DT documentation significantly improved for 2023 was 81.4% (χ 2 = 977.9, p < 0.0001). The rates of DT documentation were relatively consistent based on diagnoses codes, though lower amongst consults seen for metastatic disease (84.0% vs 73.4%, χ 2 = 24.28, p < 0.0001). Conclusions: Screening rates at consultation are modifiable and maintainable, but distress management remains a continuous quality improvement project as we explore services to address identified stressors and reassess distress levels at future visits.

Clinical utility and impact of a diagnostic oncology clinic.

74 Background: Oncologists have expertise in the work-up and management of patients with a suspected diagnosis of cancer. Patients diagnosed with cancer during acute care hospitalization often have poorer outcomes than those diagnosed as outpatients. For these patients, time to appropriate cancer diagnosis, management of cancer-related symptoms, and timely initiation of treatment are key to improved outcomes. Outpatient new diagnosis clinics may improve patient outcomes by improving access to subspecialty care. Methods: Patients seen by the inpatient oncology consult service over a two-month period (8/1/23-8/31/23 and 10/1/23-10/31/23) were included in this analysis. Inpatient management of disease was defined as an invasive procedure to treat the disease or a complication of the disease, initiation of systemic anti-neoplastic treatment, or radiation therapy. Surveys regarding perceived barriers to timely outpatient oncology care were distributed to oncology fellows and attendings. A Diagnostic Oncology Clinic (DOC) was started 2/1/2024 with the goal to decrease time to first outpatient oncology by a median of 12 days to less than 10 days, decrease hospital length of stay (LOS), improve outpatient management of cancer related symptoms, and improve time to treatment. Results: A total of 95 patients were evaluated. 74 (78%) of patients had a new diagnosis of cancer. Most patients had gastrointestinal cancer (n = 40, 42%) or thoracic cancer (n = 24, 25%). 51 patients (53.7%) had metastatic disease. 48 patients (50.5%) had an ECOG performance status of 0 or 1 at the time of consultation. The median hospital LOS was 11 days (IQR, 5-19). 13 patients (13.7%) had an inpatient PET scan and 43 patients (45.3%) required inpatient management of their disease or disease-related complication. 57 patients (60%) were discharged home, 21 (22%) to an extended care facility, and 17 (18%) expired or transitioned to hospice. 35 patients (37%) were seen as new outpatients with a median time to visit of 12 days (IQR 7-20). The median time to initiation of anti-neoplastic therapy as an outpatient was 24 days (IQR 18-33). There were 29 survey respondents corresponding to a response rate of 69%. 16 (55%) felt that about half the time or less patients will have timely follow-up with an oncologist after discharge, and 19 (65%) felt half the time or less patients will have appropriate cancer-related symptom management after discharge. Conclusions: Most patients seen by the inpatient oncology consult service with a new diagnosis of cancer have advanced and symptomatic disease. Historically, there has been significant time to outpatient care and cancer-specific management led by an oncologist. Creation of a diagnostic oncology clinic may shift some diagnostic testing and symptom management from the inpatient to outpatient setting, decrease time to first outpatient visit, and improve provider workflow for a vulnerable patient population. Analysis of this intervention is ongoing.

Multi-Institutional Study of Referral Patterns for Gynecologic Oncology Consultation.

Evaluation by a gynecologic oncologist (GO) is associated with improved clinical outcomes for patients with gynecologic cancers, yet little is known about health care factors that influence patients' referrals to GO. Medical records of 50 consecutive new patients seen in GO clinics at each of six referral centers across the United States were reviewed. Patient and disease characteristics were collected along with referral indication, evaluation and referral dates, diagnostic procedures, provider specialties, and zone improvement plan (ZIP) code of up to three referring providers per patient. The primary outcome was interval between first evaluation and referral. Univariate associations were evaluated with Chi-square and Wilcoxon rank-sum tests and multivariable associations with negative binomial regression models. Secondary outcome was prolonged time to GO referral, defined as greater than the 75th percentile. Logistic regression was used for multivariable modeling. Three hundred patient records were analyzed. The median time from first health care encounter to referral was 15 days (IQR, 5-43). The mean distance from residence to GO was 39.8 miles (standard deviation, 53.8). Seventy-one percent of GO referrals were initiated by obstetrician-gynecologists, 9% by family physicians, and 6% internists. Presentation-to-referral interval was 76% shorter for patients evaluated by an emergency medicine clinician (exp(Beta), 0.24; 95% CI, 0.11 to 0.53; P < .001). Public insurance was associated with 1.47 times longer time to referral compared with private insurance (exp(Beta), 1.47; 95% CI, 1.05 to 2.04; P = .001). Residents of nonmetropolitan ZIP codes were less likely to have prolonged time to referral (odds ratio [OR], 0.288; P = .017). Distance from residence to GO (per 10 miles) increased the likelihood of prolonged time to referral (OR, 1.10; P = .010). Interventions are needed to improve recognition and referral of patients for gynecologic oncology evaluation. Community outreach and engagement with obstetrician-gynecologists should be prioritized to improve times to referral.

Impact of Location of Residence and Distance to Cancer Centre on Medical Oncology Consultation and Neoadjuvant Chemotherapy for Triple-Negative and HER2-Positive Breast Cancer.

Despite consensus guidelines, most patients with early-stage triple-negative (TN) and HER2-positive (HER2+) breast cancer do not see a medical oncologist prior to surgery and do not receive neoadjuvant chemotherapy (NAC). To understand barriers to care, we aimed to characterize the relationship between geography (region of residence and cancer centre proximity) and receipt of a pre-treatment medical oncology consultation and NAC for patients with TN and HER2+ breast cancer. Using linked administrative datasets in Ontario, Canada, we performed a retrospective population-based analysis of women diagnosed with stage I-III TN or HER2+ breast cancer from 2012 to 2020. The outcomes were a pre-treatment medical oncology consultation and the initiation of NAC. We created choropleth maps to assess the distribution of the outcomes and cancer centres across census divisions. To assess the relationship between distance to the nearest cancer centre and outcomes, we performed multivariable regression analyses adjusted for relevant factors, including tumour extent and nodal status. Of 14,647 patients, 29.9% received a pre-treatment medical oncology consultation and 77.7% received NAC. Mapping demonstrated high interregional variability, ranging across census divisions from 12.5% to 64.3% for medical oncology consultation and from 8.8% to 64.3% for NAC. In the full cohort, compared to a distance of ≤5 km from the nearest cancer centre, only 10-25 km was significantly associated with lower odds of NAC (OR 0.83, 95% CI 0.70-0.99). Greater distances were not associated with pre-treatment medical oncology consultation. The interregional variability in medical oncology consultation and NAC for patients with TN and HER2+ breast cancer suggests that regional and/or provider practice patterns underlie discrepancies in the referral for and receipt of NAC. These findings can inform interventions to improve equitable access to NAC for eligible patients.

The reuse of electronic health records information models in the oncology domain: Studies with the bioframe framework

Objective:The reuse of Electronic Health Records (EHR) information models (e.g., templates and archetypes) may bring various benefits, including higher standardization, integration, interoperability, increased productivity in developing EHR systems, and unlock potential Artificial Intelligence applications built on top of medical records. The literature presents recent advances in standards for modeling EHR, in Knowledge Organization Systems (KOS) and EHR data reuse. However, methods, development processes, and frameworks to improve the reuse of EHR information models are still scarce. This study proposes a software engineering framework, named BioFrame, and analyzes how the reuse of EHR information models can be improved during the development of EHR systems. Methods:EHR standards and KOS, including ontologies, identified from systematic reviews were considered in developing the BioFrame framework. We used the structure of the OpenEHR to model templates and archetypes, as well as its relationship to international KOS used in the oncology domain. Our framework was applied in the context of pediatric oncology. Three data entry forms concerning nutrition and one utilized during the first pediatric oncology consultations were analyzed to measure the reuse of information models. Results:There was an increase in the adherence rate to international KOS of 18% to the original forms. There was an increase in the concepts reused in all 12 scenarios analyzed, with an average reuse of 6.55% in the original forms compared to 17.1% using BioFrame, resulting in significant differences. Conclusions:Our results point to higher reuse rates achieved due to an engineering process that provided greater adherence to EHR standards combined with semantic artifacts. This reveals the potential to develop new methods and frameworks aimed at EHR information model reuse. Additional research is needed to evaluate the impacts of the reuse of the EHR information model on interoperability, EHR data reuse, and data quality and assess the proposed framework in other health domains.

Perspectives on Academic Training in Clinical Oncology in the United Kingdom: A National Cross-Sectional Analysis

AimsThere are longstanding concerns relating to clinical academic training pipelines, with evidence for multiple barriers and enablers to clinical academic career progression. We sought to assess the extent to which these and other factors apply to academic training in clinical oncology in the United Kingdom. Materials and methodsA cross-sectional survey was undertaken using a bespoke, pre-piloted online electronic questionnaire that was distributed to clinical oncology specialty trainees and consultants who had at any point between January 2013–January 2024 commenced an academic post whilst in training. Collated information included demographic data, location and stage of training, research experience and ambitions, research skill confidence and academic career progression. ResultsSeventy eligible responses were included, representing 84% (n = 16/19) of UK training deaneries. Thirty-seven (53%) of the respondents had obtained their certificate of completion of training (CCT) whilst 11% (n = 8/70) and 40% (n = 28/70) were at specialty trainee level and respectively pre- or within-/post-doctoral studies. Of 34 post-CCT respondents, 58% (n = 20) had ongoing research commitments but this reached 30% of their overall activity for just 30% (n = 10). Barriers to academic progression included clinical training requirements, post availability and limited mentorship. Most (60%; n = 35/58) undertook doctoral studies in their final two training years. A majority of respondents lacked confidence in radiation oncology (RO) skills relevant to their career ambitions, with 60%, 40% and 30%, respectively, confident in RO clinical research outcome evaluation, in vitro radiation analyses and using RO animal models. ConclusionThese data provide a granular, long-term analysis of academic clinical oncology training at a national level; identifying poor progression to research independence underlined by limited confidence in RO research skills and multiple barriers to academic career progression. These data provide areas in which policy makers, research funders and training programmes can focus to improve academic training in clinical oncology.

Are outcomes of locally advanced cervical cancer associated with prebrachytherapy hemoglobin values and transfusion practice? An observational study comparing two large academic centres with divergent clinical guidelines

Anemia is common in locally advanced cervical cancer. Clinical practice varies greatly for management of anemia during brachytherapy, with some centres providing red cell transfusion to increase hemoglobin levels above 100 g/L. This is a retrospective observational cohort study of adult patients with cervical cancer treated with brachytherapy at two academic hospitals. One hospital (H1) uses a liberal transfusion strategy with hemoglobin threshold of 100 g/L during brachytherapy and the other uses a restrictive target of 70 g/L (H2). Overall, 336 patients met inclusion criteria (H1: 150 patients, H2: 186 patients). 11 patients were excluded (2 at H1, 9 at H2). Demographics at both sites were comparable, except for cancer stage and smoking history. External beam radiation and chemotherapy provided was similar. Hemoglobin values were compared at baseline (within 4 weeks of oncology consult), and prior to the first and second brachytherapy treatments. In total, 101red blood cell (RBC) units were transfused to patients at H1 and 19 units to patients at H2. Patients were followed for a median of 37.0 months (0.6-80.5) at H1, and 33.3 months (1.6-82.0) at H2. There was no significant difference in progression-free or overall survival. Multivariable logistic regression analysis showed that FIGO stage was a predictor for both overall survival and cancer progression. Age, tumor size, chemotherapy, and hemoglobin levels were not predictors of disease progression or mortality. The practice of liberal transfusion should be re-evaluated in the absence of robust data to support its use.
