OGC SO04 - Impact of COVID-19 on Decision-making and Survival in Esophago-Gastric Cancer Treatment: Insights from a Multidisciplinary Approach

Abstract Background The COVID-19 pandemic necessitated rapid adaptation in healthcare delivery, affecting cancer care pathways. This study assesses the impact of these changes on multidisciplinary team (MDT) decision-making and survival outcomes in esophago-gastric cancer patients across pre-pandemic, peak pandemic, and post-pandemic periods. Method A retrospective cohort study involving patients referred to a UK tertiary EG cancer center during distinct six-month intervals mirroring the pandemic's evolution. Analysis focused on MDT recommendations, treatment pathways, and two-year survival rates, comparing deviations from standard care across periods. Results The study revealed a significant reduction in patient referrals and expedited treatment decisions during the pandemic peak, with a shift towards palliative care in post-pandemic cases. Although no statistically significant difference in two-year survival rates was observed, the post-pandemic period showed an increase in tumor aggressiveness and positive resection margins, suggesting potential long-term impacts of delayed diagnosis and treatment. Conclusion COVID-19 has significantly influenced MDT decision-making and patient pathways in esophago-gastric cancer care, underlining the necessity of resilient healthcare systems. Despite maintaining survival rates, the observed increase in tumor aggressiveness post-pandemic highlights the critical need for uninterrupted cancer diagnosis and treatment services during global health emergencies.

Assessing the practice of total neoadjuvant therapy for rectal cancer: an online survey among radiation oncology departments in Germany and German-speaking regions of Austria and Switzerland.

Total neoadjuvant therapy (TNT) of rectal cancer improves rates of pathological complete remission and progression-free survival. With improved clinical response rates, interest grew in a non-operative approach/watch and wait (WaW) for this disease. In 2020, the working groups of ACO/AIO/ARO published a consensus statement on the use of TNT, including a non-operative approach. However, the best combination scheme remains unclear. Despite the increasing use of TNT, there is a lack of comprehensive data on its current implementation and practices. To address this knowledge gap, a multicenter survey was conducted to capture the use of TNT protocols in German-speaking radiotherapy departments. At the beginning of 2023, a GDPR-compliant online survey was conducted in Germany, Austria, and German-speaking Switzerland. The questionnaire comprised 43 questions covering various aspects of TNT, including chemotherapy and WaW concepts. Most respondents (98.4%) confirmed awareness of the consensus on TNT for rectal cancer. Institutions treated an average of 30.22 rectal cancer patients annually. Most respondents (76.2%) reported treating over 80% of patients neoadjuvantly. Regarding TNT, 33.3% treated 21-50% with such a protocol. No significant association was found between the institution type and TNT application. In 62/63 cases, tumor board discussion was standard before offering TNT. VMAT was the predominant technique (82.5%). For rectal cancer dosing, the 50/50.4Gy scheme was most common, followed by 45Gy with a boost and the 5 × 5Gy scheme. Dosing schemes for TNT varied slightly, with more participants reporting the use of 5 × 5Gy compared to radiation therapy for rectal cancer in general. CBCT was the primary IGRT method (88.9%). Larger hospitals typically administered chemotherapy themselves, while private practices collaborated with medical oncologists (p < 0.0001). The most common concurrent chemotherapy drugs were 5-fluorouracil/capecitabine (64.4%) and oxaliplatin (37.3%). A WaW strategy was reported to be institutional implemented by 63.8%. The timing of offering WaW was split, with 50% offering it after radiochemotherapy and 47% during the informed consent talk. For planned WaW, 62% prefer normofractionated TNT. TNT appears to be widely implemented in the German-speaking radio-oncological community, regardless of the type of institution. Image-guided therapy, multidisciplinary team decisions, and internal guidelines play an important role. TNT seems to have already altered treatment protocols for rectal cancer toward an organ-preserving approach in selected cases. In these WaW cases, normofractionation appears to be preferred over hypofractionation.

Chronic thromboembolic pulmonary disease.

Chronic thromboembolic pulmonary hypertension is a complication of pulmonary embolism and a treatable cause of pulmonary hypertension. The pathology is a unique combination of mechanical obstruction due to failure of clot resolution, and a variable degree of microvascular disease, that both contribute to pulmonary vascular resistance. Accordingly, multiple treatments have been developed to target the disease components. However, accurate diagnosis is often delayed. Evaluation includes high-quality imaging modalities, necessary for disease confirmation and for appropriate treatment planning. All patients with chronic thromboembolic pulmonary disease, and especially those with pulmonary hypertension, should be referred to expert centres for multidisciplinary team decision on treatment. The first decision remains assessment of operability, and the best improvement in symptoms and survival is achieved by the mechanical therapies, pulmonary endarterectomy and balloon pulmonary angioplasty. With the advances in multimodal therapies, excellent outcomes can be achieved with 3-year survival of >90%.

Management of periprosthetic joint infection of the shoulder: A narrative review

Evidence for management of shoulder periprosthetic joint infection (PJI) has traditionally originated from the hip and knee literature. The differing microbiome, anatomy and implants used in the shoulder mean this evidence is not always directly transferrable. The 2018 Philadelphia International Consensus Meeting for the first-time produced evidence-based guidelines and diagnostic criteria relating specifically to PJI of the shoulder. These guidelines and criteria recognize the pathogenicity of lower virulence organisms in the shoulder which often means clinical presentation is less obvious than other joints.The role of Cutibacterium acnes in shoulder PJI is the subject of increasing basic science and clinical research and advances in microbiological research may help to understand the pathology behind shoulder infections. There is new evidence that outcomes after revision shoulder arthroplasty are dependent on the virulence of the causative organism. An individualised approach to treatment considering host factors, organism, soft tissues and bone stock is recommended.Debate continues in the literature regarding the indications of one- or two-stage revision and the latest evidence is discussed and synthesized in this review article. We advocate careful multidisciplinary team decision making for cases of shoulder PJI and recognize a limited role for debridement and implant retention in acute shoulder PJI (<6 weeks). There appears to be a role for one-stage revision in lower risk cases with low virulence organisms but caution against its’ universal adoption. In higher risk or complex cases, there remains a clear role for two-stage revision arthroplasty, and we detail the specifics of this protocol and procedure from our tertiary shoulder and elbow unit.

Updating a conceptual model of effective symptom management in palliative care to include patient and carer perspective: a qualitative study

BackgroundA conceptual model of effective symptom management was previously developed from interviews with multidisciplinary healthcare professionals (HCP) working in English hospices. Here we aimed to answer the question; does a HCP data-derived model represent the experience of patients and carers of people with advanced cancer?MethodsSemi-structured interviews were undertaken with six patients with advanced cancer and six carers to gain an in-depth understanding of their experience of symptom management. Analysis was based on the framework method; transcription, familiarisation, coding, applying analytical framework (conceptual model), charting, interpretation. Inductive framework analysis was used to align data with themes in the existing model. A deductive approach was also used to identify new themes.ResultsThe experience of patients and carers aligned with key steps of engagement, decision making, partnership and delivery in the HCP-based model. The data aligned with 18 of 23 themes. These were; Role definition and boundaries, Multidisciplinary team decision making, Availability of services/staff, Clinician-Patient relationship/rapport, Patient preferences, Patient characteristics, Quality of life versus treatment need, Staff time/burden, Psychological support -informal, Appropriate understanding, expectations, acceptance and goals- patients, Appropriate understanding, expectations, acceptance and goals-HCPs, Appropriate understanding, expectations, acceptance and goals- family friends, carers, Professional, service and referral factors, Continuity of care, Multidisciplinary team working, Palliative care philosophy and culture, Physical environment and facilities, Referral process and delays. Four additional patient and carer-derived themes were identified: Carer Burden, Communication, Medicines management and COVID-19. Constructs that did not align were Experience (of staff), Training (of staff), Guidelines and evidence, Psychological support (for staff) and Formal psychological support (for patients).ConclusionsA healthcare professional-based conceptual model of effective symptom management aligned well with the experience of patients with advanced cancer and their carers. Additional domains were identified. We make four recommendations for change arising from this research. Routine appraisal and acknowledgement of carer burden, medicine management tasks and previous experience in healthcare roles; improved access to communication skills training for staff and review of patient communication needs. Further research should explore the symptom management experience of those living alone and how these people can be better supported.

Best-Practice Biomarker Testing of Oesophago-Gastric Cancer in the UK: Expert Consensus Recommendations Developed Using a Modified Delphi

AimsOesophago-gastric cancers (OGCs) are amongst the most commonly diagnosed malignancies worldwide and are associated with high disease-related mortality. Predictive biomarkers are molecules that can be objectively measured and used to indicate a likely response to therapeutic intervention, thus facilitating individualised cancer therapy. However, there remains variation in uptake and implementation of biomarker testing across the UK. Materials and methodsWe conducted a modified Delphi study to formulate consensus recommendations for best-practice biomarker testing of OGC in the UK. We employed two rounds of online questionnaires followed by a virtual consensus meeting. Biomarkers for discussion included HER2, MSI/MMR, and PD-L1. Topics comprised the overall biomarker pathway, pre-analytical, analytical, and post-analytical considerations, including challenges in current practice. ResultsTwenty-six and eighteen participants completed the first and second round Delphi questionnaire, respectively, with an even split of pathologists and oncologists from across the UK. There was consensus (>80% agreement) across several topics, including the requirements for standardisation of the pathway, which must include coordination throughout the tissue journey, requirements for a quality-assured process to ensure accuracy and validity of testing, plus the need for clear, detailed information on the pathology report to support treatment decisions. There was consensus amongst oncologists regarding reflex testing of all biomarkers depending on histology; however, concerns over capacity in relation to workload and availability of pathologists were evident among the pathologists. Overall, participants were in the opinion that reflex testing improves the speed of treatment decisions and improves patient care. ConclusionThe recommendations reflect best-practices and should be implemented to support rapid multidisciplinary team decision-making within oesophago-gastric cancer. Results reflect the need for standardisation and demonstrate the challenges faced in clinical practice by those requesting and testing biomarkers for oesophago-gastric cancer, suggesting significant concerns relating to pathologist capacity.

Surgical options of chiasmatic hypothalamic glioma—a relevant part of therapy in an interdisciplinary approach for tumor control

ObjectiveThe extent of resection of pediatric low-grade glioma mostly improves progression-free survival. In chiasmatic hypothalamic glioma (CHG), complete resections are limited due to the relevantly high risk of associated neurological and endocrinological deficits. Still, surgery might have its role in the framework of a multidisciplinary team (MDT) approach. We report our retrospective experience from two centers on surgical options and their impact on long-term outcomes.MethodsMedical records of surgically treated pediatric CHG patients between 2004 and 2022 were analyzed. Patient characteristics, surgical interventions, histology, and non-surgical therapy were retrieved together with outcome measures such as visual acuity, endocrine function, and survival.ResultsA total of 63 patients (33 female, NF-1, n = 8) were included. Age at first diagnosis was 4.6 years (range 0.2–16.9) and cohort follow-up was 108 ± 72 months. Twenty patients were surgically treated with a biopsy and 43 patients with debulking at a median age of 6.5 years (range 0.16–16.9). Patients received a median of 2 tumor surgeries (range 1–5). Cyst drainage was accomplished in 15 patients, and 27 patients had ventriculoperitoneal shunt implantation. Non-surgical therapy was given in 69.8%. At the end of follow-up, 74.6% of patients had stable disease. The cohort had a median Karnofsky score of 90 (range 0–100). Four patients died. Hormone substitution was necessary in 30.2%, and visual acuity was impaired in 66% of patients.ConclusionPediatric CHG is a chronic disease due to overall high survival with multiple progressions. Surgical therapy remains a key treatment option offering biopsy, limited tumor-debulking, cyst fenestration, and hydrocephalus management in the framework of MDT decision-making. Team experience contributes to reducing possible deficits in this challenging cohort.

Synchronous Carcinoma Cervix with Renal Cell Carcinoma: An Incidental Finding

Background In India, renal cell carcinoma (RCC) is the most frequent kidney cancer with an increasing tendency, whereas cervical cancer is the second most common disease among women. Synchronicity of RCC with other malignancies is not uncommon, but with the cervical cancer is rare.  Case description A 64-year-old, postmenopausal female, presented with complaint of bleeding per vagina and was diagnosed with carcinoma cervix and later on metastatic work-up also diagnosed with right RCC. After multidisciplinary discussion, patient planned for management for cervix then followed by renal lesion. Patient received radical external beam radiotherapy followed by brachytherapy for carcinoma cervix and underwent nephrectomy for right RCC.  Conclusion Synchronous cases of cervical cancer and renal cell carcinoma are very rare. Advancement in diagnostic protocol makes these kind of cases common and multidisciplinary team decisions are required for their management.

Lung cancer MDT quality assessment: A nationwide study.

8594 Background: This observational study evaluates concordance between lung cancer multi-disciplinary team (MDT) meetings, focusing on diagnosis, staging, and treatment recommendations, especially for curative options. Assessing MDT decisions aims to identify factors potentially affecting survival rates, promoting equal treatment access for patients nationwide. Methods: In Norway, patients with lung cancer are discussed at local MDT (without a thoracic surgeon present) and at university hospital MDT (with a thoracic surgeon present). All hospitals received 35 fictitious case reports of patients with inoperable non-small cell (NSCLC) and small cell lung cancer (SCLC) with anonymized CT and PET images for discussion at the ordinary MDT meetings. Of the 12 participating hospitals, 5 were university hospitals. Results: Of the 35 patient’s cases, 12 were assessed as having stage III NSCLC. For 10 of the 12 there were differences in stage assessment, from stage IIIA-B-C to IV, and in recommended treatment (Table). For each case, curative treatment was recommended by a varying number of MDTs, from zero to nine of 12. Treatment suggestions for the four SCLC patients were identical except for one patient with stage IV, performance status (PS) score 2-3 and stroke, for whom the recommended treatment ranged from best supportive care (BSC) to triple therapy. There was generally good consensus between recommending treatment with a tyrosine kinase inhibitor (TKI) in patients with epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) translocation positivity. We found that factors leading to discrepancies in MDT decisions were patients age &gt;75-80 years, comorbidities, PS 2 or lack of a stated PS, PD-L1 more than 50-75% in stage IV and large cell neuroendocrine carcinoma (LNEC). Conclusions: MDT-recommendations regarding treatment varied between MDT sites, and this may have the greatest consequences for patients in stage III. MDT treatment recommendations varied between the sites, confirming that treatment choice can be challenging in certain type of cases like elderly, poor PS or LNEC. Shared decision-making (SDM) with patients was often recommended. As an important outcome of the study, we found no difference in treatment choice between local and university hospital MDTs.

Impact of regulatory t cells in peripheral blood on pathological complete response in patients with locally advanced gastric or gastroesophageal junction cancer undergoing neoadjuvant chemoimmunotherapy.

e16081 Background: Neoadjuvant chemotherapy has become the standard treatment for locally advanced gastric or gastroesophageal junction (G/GEJ) cancer. With the widely clinical application of immune checkpoint inhibitors, represented by anti-PD-1 antibodies, an increasing number of patients with locally advanced G/GEJ cancer are undergoing neoadjuvant chemoimmunotherapy. However, there is currently no effective predictive marker for neoadjuvant chemoimmunotherapy in locally advanced G/GEJ cancer. We explored the role of peripheral blood regulatory T (Treg) cells in patients with locally advanced G/GEJ cancer. Methods: We retrospectively analyzed lymphocyte subpopulations before and after treatment in patients with locally advanced G/GEJ cancer who received neoadjuvant chemotherapy combined with anti-PD-1 antibodies and curative surgery. Inclusion criteria were: 1) Pathologically confirmed adenocarcinoma of the G/GEJ; 2) Clinically staged as gastric cT3-4 or N+ without distant metastasis by enhanced CT and endoscopic ultrasound examination; 3) Patients requiring neoadjuvant treatment according to gastric cancer multidisciplinary team decisions; 4) Receipt of neoadjuvant treatment with chemotherapy combined with PD-1 antibodies; 5) Completion of 3-4 cycles of treatment; 6) Underwent curative resection; 7) Lymphocyte subpopulation testing performed before the first and second cycles. Results: From July 1, 2020, to May 31, 2023, 85 patients were included. All 85 patients underwent D2 radical surgery and achieved R0 resection, with 21 patients achieving pathological complete response (pCR), resulting in a pCR rate of 24.7% (95% confidence interval (CI) 15.3-34.1%). There were no statistically significant differences in baseline characteristics between the pCR and non-pCR groups. There were no statistically significant differences in lymphocyte subpopulations between the baseline pCR and non-pCR patient groups. After one cycle of treatment (before the second cycle), there were statistically significant differences in lymphocytes, T lymphocytes, and Treg cells between the two groups. Further analysis of the absolute changes in lymphocyte subpopulations before and after one cycle of treatment revealed a greater decrease in Treg cells in the pCR group. Based on the increase or decrease in Treg cells after one cycle of treatment, the 85 patients were divided into Treg cell increase and decrease groups. The pCR rate was 11.4% (4/35, 95% CI 0.3-22.5%) in the Treg cell increase group and 34% (17/50, 95% CI 20.4-47.6%) in the Treg cell decrease group, with a statistically significant difference between the two groups ( P= 0.022). Conclusions: In locally advanced G/GEJ cancer, changes in Treg cells after one cycle of neoadjuvant treatment may serve as a predictive marker for achieving pCR.

Total Knee Arthroplasty in Patients Who Have Skeletal Dysplasia: A Center’s Experience With a Mean 9-Year Follow-Up

BackgroundTotal knee arthroplasty (TKA) in patients who have skeletal dysplasia (SD) is a technically challenging surgery due to deformity, joint contracture, and associated comorbidities. Patients presenting with this condition have traditionally been treated with conservative measures, leading to poor outcomes. The aim of this study was to follow-up on patients who had SD following TKA, specifically with regards to clinical outcomes. MethodsA total of 31 knees (22 patients) with SD that had undergone TKA in our institution were included in our study. The mean follow-up from index surgery was 110.3 months (range: 20 to 291). The type of dysplasia, implant used, and clinical outcomes with patient-reported outcome measures are presented. ResultsThere were 8 patients (36.3%) who had a diagnosis of achondroplasia, followed by multiple epiphyseal dysplasia (31.8%) and spondyloepiphyseal dysplasia (22.7%). There were 14 men and 8 women who had a mean age of 51 years (range: 28 to 73). Custom implants were required in 12 cases (38.7%), custom jigs were used in 6 cases (19.4%), and robotic-assisted surgery was used in 2 (6.5%) TKAs. Hinged prostheses were used in 17 cases (54.8%), posterior-stabilized in 9 (29.0%), and cruciate-retaining implants in 5 (16.1%). There was 1 patient who sustained an intraoperative medial tibial plateau fracture treated with concomitant open reduction and internal fixation. There was 1 revision that occurred during the follow-up period with a patella resurfacing for continued anterior knee pain. Postoperatively, Oxford Knee Scores improved on average by 12.2 points. The 10-year and 20-year all-cause revision-free survival was 96.8, respectively. ConclusionsDespite the technical challenges and complexity associated with this unique patient cohort, we demonstrated excellent implant survivorship and clinical outcomes post-TKA with mid-term to long-term follow-up of more than 20 years. We recommend preoperative cross-sectional imaging for precise planning and implant templating with multidisciplinary team decision-making. Despite our results, functional outcomes remain inferior to primary arthroplasty within the general population, although we still recommend this treatment modality to appropriately counseled patients. Level of EvidenceIII.

Deep Learning Models for Predicting Malignancy Risk in CT-Detected Pulmonary Nodules: A Systematic Review and Meta-analysis

BackgroundThere has been growing interest in using artificial intelligence/deep learning (DL) to help diagnose prevalent diseases earlier. In this study we sought to survey the landscape of externally validated DL-based computer-aided diagnostic (CADx) models, and assess their diagnostic performance for predicting the risk of malignancy in computed tomography (CT)-detected pulmonary nodules.MethodsAn electronic search was performed in four databases (from inception to 10 August 2023). Studies were eligible if they were peer-reviewed experimental or observational articles comparing the diagnostic performance of externally validated DL-based CADx models with models widely used in clinical practice to predict the risk of malignancy. A bivariate random-effect approach for the meta-analysis on the included studies was used.ResultsSeventeen studies were included, comprising 8553 participants and 9884 nodules. Pooled analyses showed DL-based CADx models were 11.6% more sensitive than physician judgement alone, and 14.5% more than clinical risk models alone. They had a similar pooled specificity to physician judgement alone [0.77 (95% CI 0.68–0.84) v 0.81 (95% CI 0.71–0.88)], and were 7.4% more specific than clinical risk models alone. They had superior pooled areas under the receiver operating curve (AUC), with relative pooled AUCs of 1.03 (95% CI 1.00–1.07) and 1.10 (95% CI 1.07–1.13) versus physician judgement and clinical risk models alone, respectively.ConclusionDL-based models are already used in clinical practice in certain settings for nodule management. Our results show their diagnostic performance potentially justifies wider, more routine deployment alongside experienced physician readers to help inform multidisciplinary team decision-making.

Abstract PO4-20-09: Successful outcome of locally advanced HR+HER2+ breast cancer treatment in a young female after pancreas-kidney transplantation. 3-year follow-up

Abstract Background Solid organs recipients with subsequent cancer comprise a group of patients with unmet medical needs: they lack any clinical trials or guidelines for treatment. There are only individual case reports in literature. Meanwhile their number is growing due to achievements in transplantology and improved cancer diagnosis. Case presentation А young 34-year-old female attended our center in September 2019 with a palpable mass and peau d'orange of the left breast. A core-needle biopsy of the left breast mass revealed invasive ductal carcinoma G3, estrogen receptor 7 (Allred), progesterone receptor 6 (Allred), HER-2 (3+), Ki-67 49%. Left axillary lymph node biopsy revealed metastatic breast cancer. After a complete examination the clinical stage was cT4bN1fM0, IIIB stage. The patient had a history of Type 1 diabetes mellitus since 2003 leading to multiple complications including terminal diabetic nephropathy, which required renal replacement therapy with the use of long-term hemodialysis since July 2014. The other complications consisted of severe retinopathy with corneal transplantation on the left eye in April 2013, an episode of right eye hemophthalmia in March 2016 with consequent loss of vision in the right eye, polyneuropathy, gastropathy and enteropathy. The patient underwent a simultaneous pancreas-kidney transplantation in April, 2016 and was on permanent immunosuppressive therapy with tacrolimus 8 mg daily and methylprednisolone 8 mg daily. The function of both transplants was satisfactory. This unique case was published by Pinchuk A. et al. in Transplant Proceedings, 2017 [doi: 10.1016/j.transproceed.2017.10.005]. A multidisciplinary approach was applied to tailoring treatment plan for this patient. Initially immunosuppressive therapy was modified: the patient discontinued methylprednisolone and started everolimus with simultaneous tacrolimus dose reduction (their doses adjusted according to blood concentrations). The tumor board decision was to start neoadjuvant therapy with regimen with the mildest and the most manageable toxicity profile and to avoid anthracyclines. From October to December 2019 the patient received 12 cycles of paclitaxel 80 mg/m2 day 1 weekly and 4 cycles of anti-HER2 dual blockade: trastuzumab 8 mg/kg day 1 followed by 6 mg/kg day 1 every 21 days + pertuzumab 840 mg day 1 followed by 420 mg day 1 every 21 days. Adverse events were: stomatitis grade 1, palmar-plantar erythrodysesthesia grade 1, diarrhea grade 2. Partial response was evaluated in the end of December 2019, but due to persistent skin edema, she was not a candidate for surgical treatment. The tumor board decision was to proceed with T-DM1 + pertuzumab based on the results of the KRISTINE trial [doi:10.1016/s1470-2045(17)30716-7]. From January to March 2020 the patient received 4 cycles of trastuzumab-emtansine 3,6 mg/kg day 1 every 21 days + pertuzumab 420 mg day 1 every 21 days. The patient tolerated this treatment with mild toxicity: ALT &amp; AST increase grade 2 and diarrhea grade 2. Considering that the edema was significantly reduced, surgical treatment was planned. The patient underwent a modified radical mastectomy for left breast cancer on 14 of April 2020. The pathological stage was ypT1аN0 R0, RCB I. The patient continued trastuzumab emtansine until November 2020 (up to 1 year of anti-HER2 targeted therapy) in the adjuvant setting. In June 2020 she underwent locoregional radiation therapy. Tamoxifen with ovarian function suppression (LHRH agonists) for 5 years was started in June 2020. Fortunately, after 3 years of follow-up after surgery there is no evidence of disease and no delayed cancer treatment complications. Conclusion: Personalized multidisciplinary team decisions for cancer patients after organ transplantation are crucial to further improve the long-term outcome of these patients.

Natural language processing to automate a web-based model of care and modernize skin cancer multidisciplinary team meetings.

Cancer multidisciplinary team (MDT) meetings are under intense pressure to reform given the rapidly rising incidence of cancer and national mandates for protocolized streaming of cases. The aim of this study was to validate a natural language processing (NLP)-based web platform to automate evidence-based MDT decisions for skin cancer with basal cell carcinoma as a use case. A novel and validated NLP information extraction model was used to extract perioperative tumour and surgical factors from histopathology reports. A web application with a bespoke application programming interface used data from this model to provide an automated clinical decision support system, mapped to national guidelines and generating a patient letter to communicate ongoing management. Performance was assessed against retrospectively derived recommendations by two independent and blinded expert clinicians. There were 893 patients (1045 lesions) used to internally validate the model. High accuracy was observed when compared against human predictions, with an overall value of 0.92. Across all classifiers the virtual skin MDT was highly specific (0.96), while sensitivity was lower (0.72). This study demonstrates the feasibility of a fully automated, virtual, web-based service model to host the skin MDT with good system performance. This platform could be used to support clinical decision-making during MDTs as 'human in the loop' approach to aid protocolized streaming. Future prospective studies are needed to validate the model in tumour types where guidelines are more complex.

Does preoperative multidisciplinary team assessment of high-risk patients improve the safety and outcomes of patients undergoing surgery?

BackgroundInternational guidelines recommend preoperative multidisciplinary team (MDT) assessment for high-risk surgical patients. Preoperative MDT meetings can help to improve surgical care, but there is little evidence on whether they improve patient outcomes.MethodsThis paper aims to share our experience of MDT meetings for high-risk surgical patients to underline their added value to the current standard of care. An observational study of a retrospective cohort of preoperative high-risk MDT meetings of a tertiary referral hospital between January 2015 and December 2020. For 249 patients the outcomes preoperative data, MDT decisions, and patient outcomes were collected from electronic health records.Main resultsA total of 249 patients were discussed at high-risk MDT meetings. Most of the patients (97%) were assessed as having an American Society of Anesthesiology score ≥ 3, and 219 (88%) had a European Society of Cardiology and European Society of Anaesthesiology risk score of intermediate or high. After MDT assessment, 154 (62%) were directly approved for surgery, and 39 (16%) were considered ineligible for surgery. The remaining 56 (23%) patients underwent additional assessments before reconsideration at a high-risk MDT meeting. The main reason for patients being discussed at the high-risk MDT meeting was to assess the risk-benefit ratio of surgery. Ultimately, 184 (74%) patients underwent surgery. Of the operated patients, 122 (66%) did not have a major complication in the postoperative period, and 149 patients (81%) were alive after one year.ConclusionsThis cohort study shows the vulnerability and complexity of high-risk patients but also shows that the use of an MDT assessment contributes too improved peri- and postoperative treatment strategies in high-risk patients. Most patients underwent surgery after careful risk assessment and, if deemed necessary, preoperative and perioperative treatment optimization to reduce their risk.
