Variation in the detection of lymphovascular invasion in T1 colorectal cancer and its impact on treatment: A nationwide Dutch study.

Lymphovascular invasion (LVI) plays an important role in determining the risk of lymph node metastasis (LNM) in T1 colorectal cancer (CRC) patients and influencing treatment decisions and patient outcomes. This study evaluated how the detection of LVI varies between Dutch laboratories and investigated its impact on the treatment and oncological outcomes of T1 CRC patients. Pathology reports and clinical data of T1 CRC patients who underwent local resection between 2015 and 2019 were obtained from the Dutch nationwide pathology databank (Palga cohort, n=5513). Data on the standard of LVI diagnosis (H&E/Immunohistochemistry) were not available. We categorized laboratories as low, average, or high detectors and evaluated the impact of LVI detection practice on the surgical resection rate and the proportion of LNM-negative (LNM-) surgeries. In the second part of the study, we used the Dutch T1 CRC Working Group cohort (n=1268) to evaluate the impact of LVI detection practice on cancer recurrences during follow-up. Multivariable logistic regression analyses and Cox proportional hazard regression were used to study the association between LVI detection practice and the outcomes. In the PALGA cohort, the proportion of surgical resections after local resection of a T1 CRC was significantly higher among patients diagnosed by laboratories with a high LVI detection rate (high vs. low: adjusted OR [aOR] 1.87; 95% confidence interval [CI] 1.52-2.31) as was the proportion of LNM-surgeries (aOR 1.73; 95% CI 1.39-2.15). In the second cohort, no significant difference was observed in cancer recurrences among patients diagnosed in laboratories with high detection rates compared with low detection rates (aHR 2.23; 95% CI 0.94-5.23). These findings suggest that a high detection rate of LVI does not improve oncological outcomes and may expose more patients to unnecessary oncological surgery, emphasizing the need for standardization of LVI diagnosis.

Incidence of Lymphedema and Other Complications in Patients Operated on for Gynecological Cancer Including Utilization of Two Lymph Node Dissection Techniques.

Background: To assess the impact of the lymph node dissection (LND) technique on short- and long-term complications. This retrospective review included patients who underwent hysterectomy, oophorectomy, and pelvic ± para-aortic LND for gynecological malignancies (cervical, endometrial, and ovarian) from 2020 to 2022 in our Gynecological Oncology Surgery clinic. Methods and Results: Among 147 patients who underwent pelvic LND for gynecological malignancy, 48 had procedures involving scissors and 99 had procedures involving unipolar cautery. There was no significant difference in the numbers of extracted pelvic and para-aortic lymph nodes between groups. The extents of LND were comparable between the scissors and unipolar cautery groups (p = 0.945). The scissors group exhibited less fluid drainage between days 2 and 5 postoperatively (1300 [600-3100] vs 1800 [600-3400]; p = 0.038). In terms of primary early and late clinical outcomes, there were no significant differences in lymphocele (16.7% vs 15.2%; p = 0.494) and lymphedema (18.8% vs 17.2%; p = 0.491) rates between groups. Conclusions: After retroperitoneal LND for gynecological malignancy, early complications such as lymphocele and late complications such as lower extremity lymphedema did not significantly differ between procedures using cold scissors and procedures using unipolar cautery.

Hematologic Predictors of Chemotherapy-Induced Neutropenia in Breast Cancer Patients Receiving Anthracycline- or Taxane-Based Chemotherapy

Background: Chemotherapy-induced neutropenia (CIN) is a common and serious complication of chemotherapy in breast cancer patients, leading to increased morbidity, mortality, and treatment disruptions. This study aimed to investigate the association between hematologic profiles and the occurrence of CIN in breast cancer patients receiving anthracycline-based or taxane-based chemotherapy. Methods: A retrospective observational analytic study with a cross-sectional design was conducted using medical records of breast cancer patients treated at the Oncology Surgery Clinic between 2022 and 2023. Sixty patients were included in the study. Hematologic profiles, including hemoglobin and leukocyte counts, were analyzed to assess their association with CIN in both anthracycline- and taxane-based chemotherapy groups. Results: The majority of patients were aged 15-64 years (86.67%), normoweight (65%), had luminal B subtype (63.3%), and were in the locally advanced breast cancer (LABC) stage (45%). Most patients were non-anemic (Hb ≥12 mg/dL) and leukopenic (71.7% and 80%, respectively). No significant association was found between age, nutritional status, or breast cancer stage and CIN (p > 0.05). However, hemoglobin and leukocyte profiles were significantly associated with CIN in both chemotherapy groups (p < 0.05). No association was found between the type of chemotherapy (anthracycline- or taxane-based) and CIN occurrence. Conclusion: Anemia (Hb <12 g/dL) and leukopenia are significant predictors of CIN in breast cancer patients, regardless of the chemotherapy regimen. These findings highlight the importance of monitoring hematologic profiles in these patients to identify those at higher risk of CIN and implement appropriate preventive and management strategies.

Transmanubrial osteomuscular sparing approach: different indications for non-pulmonary malignancies.

The transmanubrial osteomuscular sparing approach (TMA) is recommended for surgeries involving or originating from the thoracic outlet structures. We present a series of consecutive patients treated from 2014 to 2024 who underwent oncological thoracic outlet surgery for primary or metastatic (non-pulmonary) malignancies. Overall, 33 patients were included. Our procedures resulted in no mortality, seven complications (21.2%) and all surgeries achieved radical (R0) status. In the hands of experienced professionals, the TMA approach proves to be safe and conservative, enabling radical surgery for tumors of the thoracic outlet. For low-grade tumors, it avoids the need for additional combined surgical access, while for high-grade tumors, it allows for more extensive en bloc resection.

Why the changing role of head and neck surgery in oncology needs attention

Why the changing role of head and neck surgery in oncology needs attention

The COMPARE Study: Comparing Perioperative Outcomes of Oncologic Minimally Invasive Laparoscopic, Da Vinci Robotic, and Open Procedures: A Systematic Review and meta-analysis of The Evidence.

To assess 30-day outcomes of da Vinci robotic-assisted (dV-RAS) versus laparoscopic/thoracoscopic (lap/VATS) or open oncologic surgery. Complex procedures in deep/narrow spaces especially benefit from dV-RAS. Prior procedure-specific comparisons are not generalizable. PubMed, Scopus and EMBASE were systematically searched (latest: 11/17/2023) following PRISMA and PROSPERO (Reg#CRD42023466759). Randomized, prospective, and database studies were pooled as odds ratios (OR) or mean differences (MD) in R using fixed-effect or random-effects (heterogeneity significant). ROBINS-I/RoB 2 were used to assess bias. Of 56,314 unique references over 12 years from 22 countries, 230 studies (34 randomized, 74 prospective, 122 database) comparing dV-RAS to lap/VATS or open surgery across 7 procedures, 4 specialties, representing 1,194,559 dV-RAS; 1,095,936 lap/VATS and 1,625,320 open cases were included. Operative time for dV-RAS was longer than lap/VATS (MD:17.73min [9.80,25.67], P<0.01) and open surgery (MD:40.92min [28.83,53.00], P<0.01), whereas hospital stay was shorter (lap/VATS MD:-0.51d [-0.64,-0.38], P<0.01; open MD:-1.85d [-2.09,-1.62], P<0.01) and blood loss was less versus open (MD:-293.44ml [-359.53,-227.35]). There were fewer dV-RAS conversions (OR:0.44 [0.40,0.49], P<0.01), transfusions (OR:0.79 [0.72,0.88], P<0.01), postoperative complications (OR:0.90 [0.84,0.96], P<0.01), readmissions (OR:0.91 [0.83,0.99], P=0.04), and deaths (OR:0.86 [0.81,0.92], P<0.01) versus lap/VATS, and fewer transfusions (OR:0.25 [0.21,0.30], P<0.01), postoperative complications (OR:0.56 [0.52,0.61], P<0.01), readmissions (OR:0.71 [0.63,0.81], P<0.01), reoperations (OR:0.89 [0.81,0.97], P<0.01), and deaths (OR:0.54 [0.47,0.63], P<0.01) versus open surgery. Blood loss (MD:-12.26mL [-29.44,4.91], P=0.16) and reoperations (OR:1.03 [0.95,1.11], P=0.48) were similar for dV-RAS and lap/VATS. There was significant heterogeneity. Da Vinci-RAS confers benefits across oncological procedures and study designs. These results provide clinical evidence to multi-specialty-care decision-makers considering dV-RAS.

Perioperative medication therapy for Muslim patients in Germany undergoing oncological surgery: a retrospective study

PurposeEngagement of healthcare professionals with patients from diverse cultural and religious backgrounds is crucial in our multicultural society, where miscommunication and errors in medical history taking can lead to incorrect treatment. In particular, Muslim patients may present unique considerations due to their specific cultural and religious beliefs, which can significantly impact treatment outcomes. This study focuses on perioperative medication therapy for patients undergoing upper and lower gastrointestinal tract and pancreatic tumor surgery, specifically examining whether Islamic beliefs were duly considered in medication selection compared to a matching patient cohort.Materials and methodsData from January 2004 to July 2023 were analyzed. Muslim patients were identified using the onomastic method and matched with non-Muslim patients at a 1:3 ratio based on age, gender, and procedure. Analysis included examination of subcutaneous, oral, and intravenous medications, with attention to ingredients and compatibility with Islamic principles.ResultsAmong 5272 patients, only 5 met the study’s inclusion criteria as Muslim patients, undergoing procedures such as anterior rectum resection, gastrectomy, and pancreatic head resection. Their religious affiliations were not documented in the admission records. According to the matched-pair analysis, consistent treatment was performed regardless of religious beliefs. All patients received subcutaneous medication, primarily enoxaparin, instead of fondaparinux, an Islam-compliant alternative. Intravenous heparin was used once for short period. Contrary to Islamic dietary restrictions and the availability of alternatives, capsules containing animal-derived gelatin and other non-compliant medications were administered orally.ConclusionThis study underscores the importance of acknowledging Muslim patients’ cultural and religious backgrounds in the perioperative setting, as failure to do so may lead healthcare professionals to overlook their potential alternative medication needs, which are essential for providing tailored medical care in modern societies. Integration of diversity-related topics into medical curricula is essential for better preparing physicians for clinical practice and ensuring patient-centered care.

Failure Modes in Orthopedic Oncologic Reconstructive Surgery: A Review of Imaging Findings and Failure Rates.

Limb salvage surgeries utilizing endoprostheses and allografts are performed for a variety of oncologic conditions. These reconstructions can fail and require revision for many reasons, which are outlined and classified into mechanical failures (soft tissue failures, aseptic loosening, structural failure), non-mechanical failures (infection, tumor progression), and pediatric failures (physeal arrest, growth dysplasia). Distinct radiologic and clinical findings define specific failure subtypes but are sparsely illustrated in the radiology literature. Specifically, an understanding of the organizational structure of the failure modes can direct radiologists' search for post-reconstruction complications, enhance an appreciation of their prognostic significance, and facilitate research by standardizing the language and conceptual framework around outcomes. The purpose of this review is to highlight the key radiologic findings and imaging studies of each failure mode in orthopedic oncologic reconstructive surgery in the context of risk factors, failure rates, prognosis and survival statistics, and clinical decision-making regarding chemotherapy, radiation, and revision surgery.

Optimization of Exocrine Pancreatic Insufficiency in Pancreatic Adenocarcinoma Patients.

This study explores the optimization of exocrine pancreatic insufficiency (EPI) management in pancreatic adenocarcinoma patients, focusing on the scientific advancements and technological interventions available to improve patient outcomes, including oral pancreatic enzyme replacement therapy (PERT) and immobilized lipase cartridge (RELiZORB®). This was a prospective Institutional Review Board (IRB)-approved study from October 2019 through to August 2021 at the Louisville Medical Center in collaboration with Norton Healthcare and the University of Louisville Division of Surgical Oncology. Patients with a diagnosis of pancreatic adenocarcinoma (Stage 2 or 3) who underwent oncologic surgical resection were included in this study. Patients were contacted at pre-defined intervals (prior to surgery, before hospital discharge, and 2, 4, 6, and 12 weeks after surgery) to complete nutrition evaluation, EPI assessment, and quality of life questionnaires to identify the severity and frequency of gastrointestinal (GI) symptoms. EPI symptoms were reported in 28 of the 35 total patients studied (80%). Jejunostomy tubes were placed during oncologic surgery in 25 of the 35 total patients studied (71%), and 12 of the 25 patients with a jejunostomy tube utilized enzyme cartridges to manage EPI symptoms while on supplemental tube feeding (48%). EPI symptoms were reported in 8 of the 10 patients without a feeding tube (80%), and their EPI symptoms were managed with PERT alone. EPI interventions, both oral PERT and immobilized cartridges, were associated with a decrease in EPI symptoms after surgery and improved quality of life (QOL). Overall, early optimization of EPI is crucial to enhance overall patient care, return to oncology therapy after surgery, and improve quality of life in pancreatic adenocarcinoma patients.

Robot-assisted Müllerian compartment resection for cervical cancer.

Radical hysterectomy has been established as the standard treatment for early stage cervical cancers. Despite numerous efforts to standardize the technique for radical hysterectomy across varying extents of tumor invasion, success has been inconsistent. Total Müllerian Compartment Resection (TMCR), an ontogenetic compartment-based oncologic surgery initially developed for open procedures by Professor Höckel, offers a standardized approach applicable to all patients with locally confined tumors. This method holds promise for achieving thorough oncologic clearance while maintaining acceptable complication rates. Moreover, robotic-assisted surgery may further reduce morbidity compared to open surgery. In this context, we provide a detailed step-by-step description of robotically assisted Total Müllerian Compartment resection (R-TMCR) for cervical cancer and present feasibility data from a cohort of 20 patients. 20 patients with stage IA1-IB2 cervical cancer, robot-assisted resection of the Müllerian embryonic compartment was undertaken. Key metrics such as operative duration, intraoperative blood loss, and postoperative complication rates were meticulously recorded and analyzed. The duration of the surgery varied from 185 to 500 minutes, with intraoperative blood loss ranging between 5 mL and 300 mL. Postoperative hemoglobin levels dropped by -15 to 40 g/L from their preoperative values. Notably, there were no instances necessitating conversion to open surgery, and no intraoperative complications occurred. The rate of postoperative complications was 0%. Over the follow-up period, which averaged 18 months, there were no observed locoregional recurrences of cervical cancer, nor were there any deaths attributed to cervical cancer during this time. The application of robotic Müllerian compartment resection in the surgical treatment of cervical cancer is both safe and feasible. Utilizing robotic technology enables more precise and refined surgical outcomes. Combining embryonic compartment-based radical hysterectomy with the principles of membrane anatomy can standardize and optimize the surgical process, helping surgeons master radical hysterectomy more quickly and effectively.

Enhanced recovery after fetal spina bifida surgery: global practice.

Enhanced recovery after surgery (ERAS) protocols are multimodal evidence-based care plans that have been adopted for multiple surgical procedures to promote faster and better patient recovery and shorter hospitalization. This study aimed to explore whether worldwide fetal therapy centers offering prenatal myelomeningocele repair implement the ERAS principles and to provide recommendations for improved perioperative management of patients. In this survey study, a total of 53 fetal therapy centers offering prenatal surgery for open spina bifida were identified and invited to complete a digital questionnaire covering their pre-, intra- and postoperative management. An overall score was calculated per center based on compliance with 20 key ERAS principles, extrapolated from ERAS guidelines for Cesarean section, gynecological oncology and colorectal surgery. Each item was awarded a score of 1 or 0, depending, respectively, on whether the center did or did not comply with that principle, with a maximum score of 20. The questionnaire was completed by 46 centers in 17 countries (response rate, 87%). In total, 22 (48%) centers performed exclusively open fetal surgery (laparotomy and hysterotomy), whereas 14 (30%) offered both open and fetoscopic procedures and 10 (22%) used only fetoscopy. The perioperative management of patients undergoing fetoscopic and open surgery was very similar. The median ERAS score was 12 (range, 8-17), with a mean ± SD of 12.5 ± 2.4. Center compliance was the highest for the use of regional anesthesia (98%), avoidance of bowel preparation (96%) and thromboprophylaxis (96%), while the lowest compliance was observed for preoperative carbohydrate loading (15%), a 2-h fasting period for clear fluids (20%), postoperative nausea and vomiting prevention (33%) and early feeding (35%). ERAS scores were similar in centers with a short (2-5 days), medium (6-10 days) and long (≥ 11 days) hospital stay (mean ± SD, 12.9 ± 2.4, 12.1 ± 2.0 and 10.3 ± 3.2, respectively, P = 0.15). Furthermore, there was no significant association between ERAS score and surgical technique or case volume. The perioperative management of fetal spina bifida surgery is highly variable across fetal therapy centers worldwide. Standardized protocols integrating ERAS principles may improve patient recovery, reduce maternal morbidity and shorten the hospital stay after fetal spina bifida surgery. © 2024 The Author(s).

Reduction in deep organ-space infection in gynecologic oncology surgery with use of oral antibiotic bowel preparation: a retrospective cohort analysis.

Deep organ-space infection (OSI) following gynecologic surgery is a source of patient morbidity and mortality. There is currently conflicting evidence regarding the use of bowel preparation prior to gynecologic surgery to reduce the rates of infection. For the additional purpose of improving patient recovery at our own institution, a retrospective cohort study compared the rate of deep OSI in patients who received oral antibiotic bowel preparation per Nichols-Condon bowel preparation with metronidazole and neomycin. The primary aim of this study was to compare the rate of deep organ-space surgical site infection in gynecologic surgery before and after institution of an oral antibiotic bowel preparation, thus assessing whether the preparation is associated with decreased infection rate. The secondary objective was to identify other factors associated with deep organ-space site infection. A retrospective cohort study was performed. Demographic and surgical data were collected via chart review of 1,017 intra-abdominal surgeries performed by gynecologic oncologists at a single institution from April 1, 2019 to December 1, 2021. Of these, 778 met the inclusion criteria; 444 did not receive preoperative oral antibiotic bowel preparation, and 334 did receive preoperative bowel preparation. Odds ratios (ORs) were calculated, and a logistic regression model was utilized for categorical variables. Multivariable regression analysis was performed. A total of 778 patients were included. Deep OSI rate in patients who did not receive oral antibiotic bowel preparation was 2.3 % compared to 0.3 % (OR 0.13, confidence interval [CI] 0.06-1.03, p=0.02) in patients who did. Receiving oral antibiotic bowel preparation predicted absence of deep OSI (OR 0.04, CI 0.00-0.87, p=0.04). Laparotomy (OR 20.1, CI 1.6-250.2, p=0.02) and Asian race (OR 60.8, CI 2.6-1,380.5, p=0.01) were related to increased rates of deep OSI. Oral antibiotic bowel preparation predicts a reduced risk of deep OSI. This preparation is inexpensive and low-risk, and thus these clinically significant results support a promising regimen to improve surgical outcomes, and provide guidance for prospective larger studies.

Proficiency in bariatric surgery may shorten the learning curve for minimally-invasive D2 gastrectomy.

Evidence from Asian studies suggests that minimally-invasive gastrectomy achieves equivalent oncological but improved perioperative outcomes compared to open surgery. Oncological gastric resections are less frequent in European countries. Index procedures may play a role for the learning curve of minimally-invasive gastrectomy. The aim of our study was to evaluate if skills acquired in bariatric surgery allow a safe and oncologically adequate implementation of minimally-invasive gastrectomy in a cohort of european patients. In this single-center retrospective study, all patients who received primary bariatric surgery between January 2015 and December 2018 and minimally-invasive surgery for gastric cancer treated from June 2019 to January 2023 were evaluated. Primary endpoints were operation time, lymph node yield and lymph node fractions. Secondary endpoints included postoperative complications and oncological outcomes. Learning curves for two surgeons with 350 bariatric procedures and 44 minimally-invasive gastrectomies were analyzed. For bariatric surgery, the mean operation time decreased from initially 82 ± 27 to 45 ± 21min and 118 ± 28 to 81 ± 36min for sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), while the complication rate remained within the international benchmark. For laparoscopic gastrectomy (n = 30), operation times decreased but then remained stable over time. Operation times for the robotic platform were longer (302 ± 60 vs. 390 ± 48min; p < 0.001) with the learning curve remaining incomplete after 14 procedures. R0 status was achieved in 95.5% of patients; the mean number of lymph nodes retrieved was 37 ± 14 with no differences between the groups. Complete mesogastric excision was more frequently achieved during the later laparoscopic cases whereas it occurred earlier for the robotic group (p = 0.004). Perioperative morbidity was comparable to the European benchmark. Textbook outcome was achieved in 54.4% of the cases. In summary, we could demonstrate a successful skill transfer from bariatric surgery to minimally-invasive laparoscopic oncological gastric surgery enabling safe and oncologically adequate minimally-invasive D2 gastrectomy in a central European patient collective.

The 30-day readmission rate of patients with an overlap of probable sarcopenia and malnutrition undergoing major oncological surgery.

Overlapping sarcopenia and malnutrition may increase the risk of readmission in surgical oncology. Overlapping probable sarcopenia/malnutrition was found in 4.6% of 238 patients and the 30-day unplanned readmission rate was 9.0%. In multivariate analysis, the overlap of probable sarcopenia and malnutrition was a significant predictor for the 30-day unplanned readmission (OR= 8.10, 95%CI= 1.20-0.55; p=0.032). ■ Probable sarcopenia plus malnutrition was significantly associated with unplanned readmission. ■ Overlap of probable sarcopenia and malnutrition was an independent risk factor for readmission. ■ Certification of whether the patient is malnourished and/or sarcopenic preoperatively is necessary. ■ SARC-F and subjective global assessment can effectively and easily assess sarcopenia and malnutrition at admission. To assess the 30-day unplanned readmission rate and its association with overlapping probable sarcopenia and malnutrition after major oncological surgery. A prospective bicentric observational cohort study performed with adult oncological patients undergoing major surgery. The primary outcome was unplanned readmission within 30 days after discharge and the association with probable sarcopenia and malnutrition. Nutritional status and probable sarcopenia were assessed just prior to surgery. Patients classified using subjective global assessment, as B and C were malnourished. Probable sarcopenia was defined using SARC-F (strength, assistance with walking, rise from a chair, climb stairs, falls) questionnaire ≥4 points and low HGS (handgrip strength) <27kg for males and <16kg for females. Two hundred and thirty-eight patients (51.7% female) with a median age of 60 years were included. The 30-day readmission rate was 9.0% (n=20). Univariate analysis showed an association of malnutrition (odds ratio (OR) = 4.84; p=0.024) and probable sarcopenia (OR = 4.94; p=0.049) with 30-day readmission. Furthermore, when both conditions were present, the patient was almost nine times more likely to be readmitted (OR = 8.9; p=0.017). Multivariable logistic regression analysis showed that overlapping probable sarcopenia and malnutrition was an independent predictor of 30-day unplanned readmission (OR = 8.10, 95% confidence interval (95%CI) 1.20-0.55; p=0.032). The 30-day unplanned readmission rate was 9.0%, and the overlap of probable sarcopenia and malnutrition is an independent predictor for the 30-day unplanned readmission after major oncologic surgery.

Fast-track surgery applied in gynecological oncological surgical treatment: a prospective randomized trial

Background: The study aimed to compare the fast-track and traditional gynaecological oncological surgeries from postoperative recovery. Methods: A total of 107 patients undergoing gynaecological oncological surgery were randomly assigned to the FTS group (n=50) and the traditional group (n=57). Results: No significant differences in LOS (Length of hospitalization post-operation) were observed. A less total cost of hospitalization and a lower C-Reactive protein (CRP) level were found (P &lt; 0.05). Also, the trial revealed a significantly lower number of the overall complications in the FTS Group (P &lt; 0.05). Conclusions: FTS applied in gynaecological oncological surgeries is beneficial to patients in terms of the postoperative recovery. Keywords: fast track surgery; gynaecological surgery; oncological surgery; post-operative length of hospitalization; randomised controlled study.

Exploring the Link Between Factors in Musculoskeletal Oncology Surgery Fellowships and Industry Supplemental Income.

Introduction In the complex landscape of healthcare economics, the financial relationship between physicians and industry remains a topic of significant interest and reflection. While the dynamics of industry relationships in certain orthopedic subspecialties have been well documented, the intricacies of industry payments within musculoskeletal (MSK) oncology programs have yet to be thoroughly explored. In this study, we aim to examine the relationship between academic and industry productivity at the fellowship level. Additionally, we seek to identify the associations between the flow of industry supplemental income to orthopedic oncologists and the specific residency and fellowship training programs they are affiliated with. Methodology A comprehensive retrospective analysis was conducted using data from the Centers for Medicare and Medicaid Services, Scopus, and other relevant databases in 2023. This study included 19 fellowship programs across the United States, encompassing a total of 68 faculty physicians. Various variables were examined, including H-index, lifetime supplemental income, geographical location, residency affiliation, and association with top-ranked hospitals. Results A statistically significant correlation was found between academic and industry productivity at the individual faculty level (p = 0.003), but not at the fellowship level (p = 0.198). The top 10% of earners accounted for approximately 70% of the total lifetime supplemental income among all fellowship faculty. Additionally, there was no statistically significant association between lifetime supplemental income or academic productivity per fellowship and geographical region, nor with the ranking of affiliated residency programs or hospitals. Conclusions Industry productivity among individual faculty in MSK oncology fellowship programs in the United States is significantly associated with academic productivity; however, this association was not observed at the fellowship level. Furthermore, no statistically significant relationship was found regarding the region or the ranking of the affiliated residency programs or hospitals.

Disparities in neighborhood deprivation and patient reported quality of life relating to post-operative sequelae after radical cystectomy.

141 Background: Readmissions following radical cystectomy(RC) remain high despite prehabilitation and enhanced recovery after surgery (ERAS) care. Recently, studies have shown the correlation between socioeconomic neighborhood deprivation (ND) and post-operative quality of life (QoL) in oncologic surgeries. We sought to examine the impact of preoperative QoL and ND with postoperative sequela following RC. Methods: This was a prospective IRB approved study of patients undergoing RC for bladder cancer from 2021 to 2023. QoL was assessed with the FACT-Bl-Cys survey. Clinicopathologic, complication, and readmission data were collected up to 90 days, as well as distance from the hospital and 4 zip-code based Indices (1-100 index scores representing socioeconomic deprivation). FACT-BL-Cys and indices scores were correlated with outcomes of interest. Pairwise Spearman correlation was done between indices and QoL Instruments. A multivariable analysis (MVA) identified the factors that influence complications and readmissions. Results: The cohort consisted of 56 patients, mostly men (n=40, 71%). Median age was 69, most had organ-confined disease (≤(y)pT2N0M0, n =45, 80%) and underwent neoadjuvant chemotherapy (n=32, 57%). 75% underwent a continent diversion (neobladder n=38, 68% or continent cutaneous diversion n=4, 7%). Median follow-up time was 10.1 months (range 3.7 - 16.7 months). No correlation was observed between 30/90-day complications or readmissions with FACT-BL-Cys. Healthy Places Index (HPI) correlated with overall QoL and subscores. On MVA, correlation was seen between Social Deprivation Index (SDI) and 90-day readmissions (p=0.03, OR=0.97, 95%CI= 0.94-0.99). Conclusions: Patient-reported QoL aligns with diverse socioeconomic strata, as per deprivation indices, which in turn correlate with readmissions. Further studies are needed to understand the relationship between patient reported QoL and ND with postoperative outcomes.

Robotic Surgery for Gynecologic Cancer: Optimism or Controversy in Surgical Oncology?

Robotic Surgery has made possible to remove cancerous organs and tissues in gynecologic cancer patients with less invasive methods. Gynecologist have observed that these minimally invasive surgeries often result in fewer complications and a faster recovery time. As robotic technology continues to develop, the potential advantages of robotic surgery in gynecologic oncology are becoming increasingly evident. Robotic Surgery offers greater precision and control during complex procedures, which can lead to improved patient outcomes and fewer complications. Robotic surgery can often outcome in smaller hospital halts and a rapid return to normal activities. Consequently, more and more GOs are adopting Robotic Surgery to provide their patients with the most advanced and effective treatment options available. Robotic Surgery is now a viable option compared to traditional open surgery. Since its extensive use, negligibly aggressive surgery has become a suitable choice not only for those with severe obesity, but also for women with gynecologic cancers, where traditional open surgery is often associated with significant complications.

Robotic Surgery in Paediatric Oncology: Expanding Boundaries and Defining Relevant Indications

This article reviews the establishment and progress of the Multidisciplinary Paediatric Robotic Program in a high-volume paediatric surgery department at Hôpital Necker-Enfants Malades, Paris, France. A major foundational principle of the program was to establish a safe and secure environment for patients and staff, both pre-operatively, intra-operatively and post-operatively. This founding principle when applied systematically has allowed increasing confidence across the program and service. The robotic platform allows for precision surgery when approaching tumours, with freedom of movement adapted to meticulous vascular and organ dissection. Surgical feasibility is based on tumour characteristics, pre-operative imaging, with a focus on vascular and organ involvement, considering goals of surgery and surgical experience. Case complexity has been gradually increased (where appropriate) through an iterative process. The future of surgery is robotic, and even more so image-guided surgery, and this synergy has been instrumental when approaching tumour surgery in children. The current principles that guide application of robot-assisted surgery in paediatric tumours are presented. With this blueprint, excellent oncological outcomes can be achieved while utilising a minimally invasive approach in children with selected endocrine, neuroblastic and renal tumours.

Use of ambient AI scribing: Impact on physician administrative burden and patient care.

418 Background: Medical documentation is necessary to describe encounters for clinical and billing purposes. The increasing time required for medical documentation is contributing to provider stress and burnout. Physicians divide their time and attention between patients and the electronic health record (EHR), negatively impacting the patient physician relationship. Methods: 49 physicians from Texas Oncology participated in a pilot from November 2023 to April 2024 using Deep Scribe (DS) ambient artificial intelligence (AI) technology to document patient clinic visits. Subspecialties of medical oncology, radiation oncology, urology, and breast surgery completed opinion surveys pre and post pilot. Provider adoption, weekly usage, satisfaction scores were measured. Evaluation and management (E&amp;M) diagnosis codes for office visits conducted pre-pilot were reviewed for over 27,000 patient encounters and compared to over 4,500 DS patient encounters. Hierarchical condition category (HCC) codes captured via DS AI were compared to manual capture of billing codes in the pre-pilot period. Results: 77% of providers adopted DS AI technology during the pilot. Median turnaround time for notes was less than 3 minutes. Average satisfaction score was 81%. 91% of providers stated DS was easy to use. 60% of providers believed DS improved the quality of documentation. Providers reported on average 1.5 hours per provider time saved per week. The average number of billed diagnosis codes for non- DS patients was 3 per patient. For the DS patients, the average billed diagnosis per patient was 4.1. Diagnosis codes were categorized as cancer, and other non-cancer HCCs using the CMS-HCC model category version 22. Of the top ten HCC categories, cancer diagnosis codes were better captured by manual coding, whereas DS captured more non-cancer HCC codes across multiple systems, most significantly in endocrine and cardiovascular systems. Conclusions: Data from this pilot study shows physicians reported DS AI improved quality of their documentation and saved physicians’ time. Billing data shows increase capture of non-cancer HCC codes. Use of AI in medical documentation can decrease physician burden and improve quality of patient care.
