Long-term oncological outcomes of follicular thyroid cancer in adolescents and young adults: A nationwide population-based study.

BACKGROUND: Follicular thyroid carcinoma (FTC) in adolescents and young adults (AYAs) is rare and data on long-term oncological outcomes are scarce. This study aimed to describe the long-term recurrence and survival rates of AYAs with FTC, and identify risk factors for recurrence. METHODS: This is a retrospective cohort study combining two national databases, including all patients aged 15-39 years, diagnosed with FTC in The Netherlands between 2000 and 2016. Age, sex, tumor size, focality, positive margins, angioinvasion, pT-stage, and pN-stage were included in a Cox proportional hazard model to identify risk factors for recurrence. RESULTS: We included 192 patients. Median age was 31.0 years (IQR 24.7-36.3) and the male to female ratio was 1:4.1. Most patients presented with a minimally invasive FTC (MI-FTC) (95%). Five patients presented with synchronous metastases (2.6%), including two with locoregional metastases (1%) and three with distant metastases (1.6%). During a median follow-up of 12.0 years, three patients developed a recurrence (1.6%), of which one patient developed a local recurrence (33%), and two patients a distant recurrence (67%). Five patients died during follow-up (2.6%). Cause of death was not captured. A Cox proportional hazard model could not be performed due to the low number of recurrences. CONCLUSIONS: FTC in AYAs is generally characterized as a low-risk tumor, as it exhibits a very low recurrence rate, a high overall survival, and it typically presents as MI-FTC without synchronous metastases. These findings underscore the favorable long-term oncological prognosis of FTC in AYAs.

The effect of liver surgery and fluid strategy on renin activity and aldosterone and anti-diuretic hormone levels: a secondary analysis of the GALILEO trial.

BACKGROUND: It is unknown whether liver surgery leads to increased RAAS activity and anti-diuretic hormone (ADH) levels and subsequent fluid accumulation. Furthermore, it is unknown whether the peri-operative fluid strategy changes this effect. METHODS: This is a pre-planned post hoc analysis of a randomised controlled trial which compared restrictive (n = 20) versus liberal fluid strategy (n = 20) in patients undergoing liver surgery. Primary outcomes for the current study were the difference in hormone levels after anaesthesia induction and after liver resection. Fluid overload was defined as a ≥10% increase in weight. RESULTS: Renin activity (6 [2.1-15.5] vs. 12 [4.6-33.5]) and ADH levels (6.0 [1.7-16.3] vs. 3.8 [1.6-14.7]) did not differ significantly before and after resection. However, aldosterone levels were significantly higher after resection (0.30 [0.17-0.49] vs. 0.69 [0.31-1.21] ). Renin activity and aldosterone levels did not differ between the groups. ADH was significantly higher in the restrictive strategy group (1.6 [1.1-2.1] vs 5.9 [3.8-16.0]). No differences in hormone levels were found in patients with and without fluid overload. DISCUSSION: Aldosterone levels increased after liver surgery but renin activity and ADH levels did not. ADH levels were higher in the restrictive group. Development of post-operative fluid overload was not associated with RAAS activity or ADH levels.

Surgical outcomes in surgical oncology patients who participated in a family involvement program.

BACKGROUND: There is a lack of evidence regarding the relationship between family involvement and outcomes in gastrointestinal oncology patients after surgery. To evaluate the effect of a family involvement program for patients undergoing oncologic gastrointestinal surgery on unplanned readmissions within 30 days after surgery. METHODS: A multicenter patient-preference cohort study compared 2 groups: patients who participated in the family involvement program versus usual care. The program comprised involvement of family caregivers in care and training of health care professionals in family-centered care. Multivariable regression analyses were used to evaluate the effect of the FIP on the number of unplanned readmissions up to 30 days after surgery. Secondary outcomes included complications sensitive to fundamental care activities, emergency department visits, intensive care unit admissions, hospital length of stay, and the need for professional home care after discharge. RESULTS: Of the 301 patients included, 152 chose the family involvement program, and 149 chose usual care. Postoperative readmissions occurred in 25 (16.4%) patients in the family involvement program group, and 15 (10.1%) in the usual care group (P = .11). A significant reduction of 16.2% was observed in the need for professional home care after discharge in the family involvement program group (P < .01). No significant differences were found between the 2 groups in the other secondary outcomes. CONCLUSION: The family involvement program did not reduce the number of unplanned readmissions, but it led to a substantial reduction in-home care, which suggests an economic benefit from a societal perspective. Implementation of the family involvement program should, therefore, be considered in clinical practice.

Family caregiver outcomes after participating in a Hospital-based family involvement program after major gastrointestinal surgery: a subgroup analysis of a patient preferred cohort study.

BACKGROUND: Engaging families in postsurgical care is potentially beneficial for improving cancer patient outcomes and quality of care. We developed a family involvement program (FIP) and in this study, we aim to evaluate the impact of the FIP on family caregiver burden and well-being. Moreover, we aim to assess the fidelity of the program. MATERIALS AND METHODS: This is a preplanned subgroup analysis of a patient-preferred prospective cohort study that included family caregivers of patients who underwent major oncological surgery for gastrointestinal tumors. Only patient-nominated family caregivers could participate in the FIP. Caregivers received structured training in fundamental caregiving tasks from healthcare professionals and then actively participated in these tasks. Caregiver burden and wellbeing were measured four times (at hospital admission, at hospital discharge, and at one and three months post-hospital discharge) using the Caregiver Strain Index+ (CSI+) and the Care-related Quality of Life instrument (CarerQoL-7D). The fidelity of the FIP was assessed by recording completion of care activities. In addition, family caregivers were asked whether they would participate in the FIP again. RESULTS: Most of the 152 family caregivers were female (77.6%), and their mean age was 61.3 years (SD=11.6). Median CSI+ scores ranged between -1 and 0 and remained below the cutoff point of experiencing burden. CarerQoL-7D results indicated no significant differences in family caregivers' well-being over time. Upon discharge, over 75% of the family caregivers stated that they would recommend the FIP to others. The highest compliance with all fundamental care activities was observed during postoperative days 2 to 4. CONCLUSION: The family caregivers of oncological surgical patients who participated in the FIP exhibited acceptable levels of caregiver burden and well-being. These findings suggest that the FIP is a valuable intervention to equip family caregivers with the skills to navigate the uncertain period following a patient's hospital discharge.

Intraoperative Fluorescence Imaging During Robotic Pancreatoduodenectomy to Detect Suture-Induced Hypoperfusion of the Pancreatic Stump as a Predictor of Postoperative Pancreatic Fistula (FLUOPAN): Prospective Proof-of-concept Study.

Background: A potential downside of robotic pancreatoduodenectomy (RPD) is the lack of tactile feedback when tying sutures, which could be especially perilous during pancreatic anastomosis. Near-infrared fluorescence imaging with indocyanine green (NIRF-ICG) could detect transpancreatic-suture-induced hypoperfusion of the pancreatic stump during RPD, which may be related to postoperative pancreatic fistula (POPF) grade B/C, but studies are lacking. Methods: This prospective study included 37 patients undergoing RPD to assess the relation between pancreatic stump hypoperfusion as objectified with NIRF-ICG using Firefly and the rate of POPF grade B/C. In 27 patients, NIRF-ICG was performed after tying down the transpancreatic U-sutures. In 10 'negative control' patients, NIRF-ICG was performed before tying these sutures. Results: Pancreatic stump hypoperfusion was detected using NIRF-ICG in 9/27 patients (33%) during RPD. Hypoperfusion was associated with POPF grade B/C (67% [6/9 patients] versus 17% [3/18 patients], P = 0.026). No hypoperfusion was objectified in 10 'negative controls'. Conclusions: Transpancreatic-suture-induced pancreatic stump hypoperfusion can be detected using NIRF-ICG during RPD and was associated with POPF grade B/C. Surgeons could use NIRF-ICG to adapt their suturing approach during robotic pancreatico-jejunostomy. Further larger prospective studies are needed to validate the association between transpancreatic-suture-induced hypoperfusion and POPF.

Which, how, and what? Using digital tools to train surgical skills; a systematic review and meta-analysis.

Background: Digital tools like digital box trainers and VR seem promising in delivering safe and tailored practice opportunities outside of the surgical clinic, yet understanding their efficacy and limitations is essential. This study investigated Which digital tools are available to train surgical skills, How these tools are used, How effective they are, and What skills they are intended to teach. Methods: Medline, Embase, and Cochrane libraries were systematically reviewed for randomized trials, evaluating digital skill-training tools based on objective outcomes (skills scores and completion time) in surgical residents. Digital tools effectiveness were compared against controls, wet/dry lab training, and other digital tools. Tool and training factors subgroups were analysed, and studies were assessed on their primary outcomes: technical and/or non-technical. Results: The 33 included studies involved 927 residents and six digital tools; digital box trainers, (immersive) virtual reality (VR) trainers, robot surgery trainers, coaching and feedback, and serious games. Digital tools outperformed controls in skill scores (SMD 1.66 [1.06, 2.25], P < 0.00001, I2 = 83 %) and completion time (SMD -1.05 [-1.72, -0.38], P = 0.0001, I2 = 71 %). There were no significant differences between digital tools and lab training, between tools, or in other subgroups. Only two studies focussed on non-technical skills. Conclusion: While the efficacy of digital tools in enhancing technical surgical skills is evident - especially for VR-trainers -, there is a lack of evidence regarding non-technical skills, and need to improve methodological robustness of research on new (digital) tools before they are implemented in curricula. Key message: This study provides critical insight into the increasing presence of digital tools in surgical training, demonstrating their usefulness while identifying current challenges, especially regarding methodological robustness and inattention to non-technical skills.

Bilaterality, not multifocality, is an independent risk factor for recurrence in low-risk papillary thyroid cancer.

BACKGROUND: The impact of multifocality and bilaterality on recurrence in patients with low-risk papillary thyroid cancer (PTC) is relevant when considering patients for a de-escalated treatment strategy: hemithyroidectomy instead of total thyroidectomy followed with or without radioactive iodine. This study aims to analyze contralateral tumor probability in patients treated for low-risk PTC and assess multifocality and bilaterality as possible predictors for recurrence. METHODS: Patients with low-risk PTC treated with total thyroidectomy followed with or without radioactive iodine in the Netherlands between 2005 and 2015 were included in this study. Patients were identified from the Netherlands Comprehensive Cancer Organization (IKNL) and linked with the nationwide network and registry of Pathology in the Netherlands (PALGA). Contralateral tumor probability and recurrence were assessed. RESULTS: Of 791 included patients, 41.8% (331 of 791) had multifocal disease, with 68.9% (228 of 331) of those patients having bilateral disease. The contralateral tumor probability after hemithyroidectomy was 24.6% (150 of 610) for patients with unifocal disease and 43.1% (78 of 181) for patients with multifocal disease. We found a higher trend of recurrence in patients with bilateral disease, regardless of multifocality: in patients with contralateral disease after precompletion diagnosed unifocal disease 7.3% (11 of 150) had recurrent disease, and patients without contralateral disease after precompletion diagnosed multifocal disease 1.9% (2 per 103) had recurrence. Cox regression analysis showed that bilaterality (hazard ratio = 3.621, 95% confidence interval = 1.548 to 8.471) was the sole statistically significant risk factor for recurrence. CONCLUSION: Low recurrence rates are found in patients with either multifocal or bilateral disease with low-risk PTC. Bilaterality should be taken into account when considering these patients for de-escalated treatment strategy.

Evidence-Based Medicine Course in Combination With Journal Clubs to Promote Evidence-Based Surgery.

Introduction To provide high-quality surgical care, surgeons must critically appraise medical literature to adapt their clinical practice whenever convincing evidence emerges. This will promote evidence-based surgery (EBS). Over the last decade, we have organized monthly journal clubs (JCs) and more extensive quarterly EBS courses for surgical residents and PhD students, supervised by surgical staff. We evaluated the participation, satisfaction, and knowledge gained by this EBS program, to make the program future-proof and aid other educators. Materials and methods An anonymous digital survey was distributed via email among residents, PhD students, and surgeons of the Amsterdam University Medical Centers' (UMC) surgical department in April 2022. The survey included general questions on EBS education, specific course-oriented questions for the residents and PhD students, and questions about supervision for surgeons. Results The survey was completed by 47 respondents from the surgery department of the Amsterdam UMC University Hospital, of whom 63.8% (n=30) were residents or PhD students and 36.2% (n=17) were surgeons. During one year of the combined EBS course and JCs, the EBS course was attended by 40.0% (n=12) of PhD students and was rated with a mean score of 7.6/10. JCs were attended by 86.6% (n=26) of residents or PhD students and received a mean score of 7.4/10. Reported strengths of the JCs were their easy accessibility and the acquisition of critical appraisal skills and scientific knowledge. A reported point of improvement was to focus more deeply on specific epidemiological topics per meeting. Of the surgeons, 64.7% (n=11) had supervised at least one JC and gave a mean score of 8.5/10. The main reasons to supervise JCs were the distribution of knowledge (45.5%), scientific discussion (36.3%), and contact with PhD students (18.1%). Conclusion Our EBS educational program, including JCs and EBS courses, was well appreciated by residents, PhD students, and staff. This format is advocated for other centers aiming to better implement EBS in surgical practice.

Clinical Prediction Models for Recurrence in Patients with Resectable Grade 1 and 2 Sporadic Non-Functional Pancreatic Neuroendocrine Tumors: A Systematic Review.

Recurrence after resection in patients with non-functional pancreatic neuroendocrine tumors (NF-pNET) has a considerable impact on overall survival. Accurate risk stratification will tailor optimal follow-up strategies. This systematic review assessed available prediction models, including their quality. This systematic review followed PRISMA and CHARMS guidelines. PubMed, Embase, and the Cochrane Library were searched up to December 2022 for studies that developed, updated, or validated prediction models for recurrence in resectable grade 1 or 2 NF-pNET. Studies were critically appraised. After screening 1883 studies, 14 studies with 3583 patients were included: 13 original prediction models and 1 prediction model validation. Four models were developed for preoperative and nine for postoperative use. Six models were presented as scoring systems, five as nomograms, and two as staging systems. The c statistic ranged from 0.67 to 0.94. The most frequently included predictors were tumor grade, tumor size, and lymph node positivity. Critical appraisal deemed all development studies as having a high risk of bias and the validation study as having a low risk of bias. This systematic review identified 13 prediction models for recurrence in resectable NF-pNET with external validations for 3 of them. External validation of prediction models improves their reliability and stimulates use in daily practice.

Position paper from the Endocrine Task Force of the European Organisation for Research and Treatment of Cancer (EORTC) on the management and shared decision making in patients with low-risk micro papillary thyroid carcinoma.

The incidence of differentiated thyroid cancer (DTC) has been increasing worldwide, mostly, as an increase in the incidental detection of micro papillary thyroid carcinomas (microPTCs), many of which are potentially overtreated, as suggested by the unchanged mortality. Several international guidelines have suggested a less aggressive approach. More recently, it has been shown that active surveillance or minimally invasive treatments (MIT) are good alternatives for the management of these patients. In this context, patient participation in the decision-making process is paramount. The Endocrine Task Force of the European Organisation for Research and Treatment of Cancer (EORTC) has undertaken the task to establish consensus and define its position based on the scientific evidence concerning, 1) the current state of diagnostic and management options in microPTCs, including the current opinion of physicians about shared decision making (SDM), 2) the available evidence concerning patients' needs and the available decision instruments, and 3) to provide practical suggestions for implementation of SDM in this context. To improve SDM and patients' participation, knowledge gaps and research directions were highlighted.

Activating Relatives to Get Involved in Care After Surgery: Protocol for a Prospective Cohort Study.

BACKGROUND: Postoperative complications and readmissions to hospital are factors known to negatively influence the short- and long-term quality of life of patients with gastrointestinal cancer. Active family involvement in activities, such as fundamental care activities, has the potential to improve the quality of health care. However, there is a lack of evidence regarding the relationship between active family involvement and outcomes in patients with gastrointestinal cancer after surgery. OBJECTIVE: This protocol aims to evaluate the effect of a family involvement program (FIP) on unplanned readmissions of adult patients undergoing surgery for malignant gastrointestinal tumors. Furthermore, the study aims to evaluate the effect of the FIP on family caregiver (FC) burden and their well-being and the fidelity of the FIP. METHODS: This cohort study will be conducted in 2 academic hospitals in the Netherlands. The FIP will be offered to adult patients and their FCs. Patients are scheduled for oncological gastrointestinal surgery and have an expected hospital stay of at least 5 days after surgery. FCs must be willing to participate in fundamental care activities during hospitalization and after discharge. Consenting patients and their families will choose to either participate in the FIP or be included in the usual care group. According to the power calculation, we will recruit 150 patients and families in the FIP group and 150 in the usual care group. The intervention group will receive the FIP that consists of information, shared goal setting, task-oriented training, participation in fundamental care, presence of FCs during ward rounds, and rooming-in for at least 8 hours a day. Patients in the comparison group will receive usual postoperative care. The primary outcome measure is the number of unplanned readmissions up to 30 days after surgery. Several secondary outcomes will be collected, that is, total number of complications (sensitive to fundamental care activities) at 30 and 90 days after surgery, emergency department visits, intensive care unit admissions up to 30 and 90 days after surgery, hospital length of stay, patients' quality of life, and the amount of home care needed after discharge. FC outcomes are caregiver burden and well-being up to 90 days after participating in the FIP. To evaluate fidelity, we will check whether the FIP is executed as intended. Univariable regression and multivariable regression analyses will be conducted. RESULTS: The first participant was enrolled in April 2019. The follow-up period of the last participant ended in May 2022. The study was funded by an unrestricted grant of the University hospital in 2018. We aim to publish the results in 2023. CONCLUSIONS: This study will provide evidence on outcomes from a FIP and will provide health care professionals practical tools for family involvement in the oncological surgical care setting.

Digital Training Resources in the Dutch Surgical Residency Curricula and the Perspectives of Residents: A Thematic Analysis of Resident Interviews.

BACKGROUND: Digital training resources show great promise in augmenting traditional surgical education - especially in times of social distancing and limited surgical caseload. Embedding digital resources in surgical curricula is however not current, nor common practice in Dutch hospitals. While the digital world has become part of a resident's everyday life, surprisingly little is known about surgical residents' experiences and expectations towards use of digital resources for their own surgical education. This study aims to identify digital resources currently used in Dutch surgical curricula and to describe surgical residents' perspectives towards digital education. METHODS: A series of semi-structured interviews with Dutch surgical residents were conducted until data sufficiency occurred. The interviews consisted of two parts: 1) current surgical training and implemented digital resources, and 2) future surgical training and the role of digital resources therein. All interviews were digitally recorded, transcribed verbatim, and thematically analyzed. RESULTS: Sixteen surgical residents were interviewed - two out of each of the eight educational regions for surgery in the Netherlands. Five digital resource categories were identified and four general educational themes (requirements, advantages, disadvantages, and general education themes), overarching 13 sub-themes. In general, residents were enthusiastic with regard to using digital resources, especially when the perceived advantages supported their autonomy. CONCLUSIONS: Dutch surgical residents indicate that digital resources may support their educational experiences, but state that ideally they must be combined with much appreciated on-the-job training, and be offered to them tailored to their individual needs. No resources are considered to be a "magic bullet" in itself. The specific needs of residents and educators need to be addressed clearly in order to successfully adopt and implement digital resources on a larger scale.

Surveillance of high-risk early postsurgical patients for real-time detection of complications using wireless monitoring (SHEPHERD study): results of a randomized multicenter stepped wedge cluster trial.

Background: Vital signs measurements on the ward are performed intermittently. This could lead to failure to rapidly detect patients with deteriorating vital signs and worsens long-term outcome. The aim of this study was to test the hypothesis that continuous wireless monitoring of vital signs on the postsurgical ward improves patient outcome. Methods: In this prospective, multicenter, stepped-wedge cluster randomized study, patients in the control group received standard monitoring. The intervention group received continuous wireless monitoring of heart rate, respiratory rate and temperature on top of standard care. Automated alerts indicating vital signs deviation from baseline were sent to ward nurses, triggering the calculation of a full early warning score followed. The primary outcome was the occurrence of new disability three months after surgery. Results: The study was terminated early (at 57% inclusion) due to COVID-19 restrictions. Therefore, only descriptive statistics are presented. A total of 747 patients were enrolled in this study and eligible for statistical analyses, 517 patients in the control group and 230 patients in the intervention group, the latter only from one hospital. New disability at three months after surgery occurred in 43.7% in the control group and in 39.1% in the intervention group (absolute difference 4.6%). Conclusion: This is the largest randomized controlled trial investigating continuous wireless monitoring in postoperative patients. While patients in the intervention group seemed to experience less (new) disability than patients in the control group, results remain inconclusive with regard to postoperative patient outcome due to premature study termination. Clinical trial registration: ClinicalTrials.gov, ID: NCT02957825.

Analyzing and Discussing Human Factors Affecting Surgical Patient Safety Using Innovative Technology: Creating a Safer Operating Culture.

INTRODUCTION: Surgical errors often occur because of human factor-related issues. A medical data recorder (MDR) may be used to analyze human factors in the operating room. The aims of this study were to assess intraoperative safety threats and resilience support events by using an MDR and to identify frequently discussed safety and quality improvement issues during structured postoperative multidisciplinary debriefings using the MDR outcome report. METHODS: In a cross-sectional study, 35 standard laparoscopic procedures were performed and recorded using the MDR. Outcome data were analyzed using the automated Systems Engineering Initiative for Patient Safety model. The video-assisted MDR outcome report reflects on safety threat and resilience support events (categories: person, tasks, tools and technology, psychical and external environment, and organization). Surgeries were debriefed by the entire team using this report. Qualitative data analysis was used to evaluate the debriefings. RESULTS: A mean (SD) of 52.5 (15.0) relevant events were identified per surgery. Both resilience support and safety threat events were most often related to the interaction between persons (272 of 360 versus 279 of 400). During the debriefings, communication failures (also category person) were the main topic of discussion. CONCLUSIONS: Patient safety threats identified by the MDR and discussed by the operating room team were most frequently related to communication, teamwork, and situational awareness. To create an even safer operating culture, educational and quality improvement initiatives should aim at training the entire operating team, as it contributes to a shared mental model of relevant safety issues.

Impact of family visit restrictions due to COVID-19 policy on patient outcomes: A cohort study.

AIM: To investigate the impact of family visit restrictions during the COVID-19 pandemic on deliriums, falls, pneumonia, pressure ulcers and readmissions among surgical inpatients with gastrointestinal (oncologic) diseases. DESIGN: Cohort study. METHODS: This study was conducted among adult inpatients undergoing gastrointestinal surgery in two academic hospitals. During the COVID-19 outbreak in 2020, over a 10-week period, one cohort was subjected to family visit restrictions. Per patient, one person per day was allowed to visit for a maximum of 30 min. This cohort was compared with another cohort in which patients were not subjected to such restrictions during a 10-week period in 2019. Logistic regression analyses were used to investigate the impact of the restrictions on deliriums, falls, pneumonia, pressure ulcers and readmissions. RESULTS: In total, 287 patients were included in the 2020 cohort and 243 in the 2019 cohort. No differences were observed in the cohorts with respect to baseline characteristics. Logistic regression analyses showed no significant differences in deliriums, falls, pneumonia, pressure ulcers and readmissions between the cohorts. CONCLUSION: We cautiously conclude that the family visit restrictions during the COVID-19 pandemic did not contribute to deliriums, falls, pneumonia, pressure ulcers or readmissions in surgical patients with gastrointestinal (oncologic) diseases. IMPACT: COVID-19 influenced family-centred care due to family visit restrictions. Nurses need to continue monitoring outcomes known to be sensitive to family-centred care to gain insight into the effects of visit restrictions and share the results in order to include nurses' perspectives in COVID-19-decision-making. Re-implementing of family visit restrictions should be carefully considered in policy-making.

Long-Term Oncological Outcomes of Papillary Thyroid Cancer and Follicular Thyroid Cancer in Children: A Nationwide Population-Based Study.

Introduction: Pediatric thyroid carcinoma is a rare malignancy and data on long-term oncological outcomes are sparse. The aim of this study was to describe the long-term oncological outcomes of pediatric papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) in a national cohort, and to identify risk factors for recurrence. Methods: We conducted a nationwide, retrospective cohort study, in which we combined two national databases. Patients aged <18 years, diagnosed with PTC or FTC in the Netherlands between 2000 and 2016, were included. pT-stage, pN-stage, multifocality and angioinvasion were included in a Cox-regression analysis for the identification of risk factors for recurrence. Results: 133 patients were included: 110 with PTC and 23 with FTC. Patients with PTC most often presented with pT2 tumors (24%) and pN1b (45%). During a median follow-up of 11.3 years, 21 patients with PTC developed a recurrence (19%). Nineteen recurrences were regional (91%) and 2 were pulmonary (9%). No risk factors for recurrence could be determined. One patient who developed pulmonary recurrence died two years later. Cause of death was not captured. Patients with FTC most often presented with pT2 tumors (57%). One patient presented with pN1b (4%). In 70%, no lymph nodes were collected. None of the patients with FTC developed a recurrence or died. Conclusion: Pediatric PTC and FTC are two distinct diseases. Recurrence in pediatric PTC is common, but in FTC it is not. Survival for both pediatric PTC and FTC is very good.

Impact of a surgical ward breakfast buffet on nutritional intake in postoperative patients: A prospective cohort pilot study.

BACKGROUND: An early return to normal intake and early mobilization enhances postoperative recovery. However, one out of six surgical patients is undernourished during hospitalization and approximately half of the patients eat 50% or less of the food provided to them. We assessed the use of newly introduced breakfast buffets in two wards for gastrointestinal and oncological surgery and determined the impact on postoperative protein and energy intake. METHODS: A prospective pilot cohort study was conducted to assess the impact of the introduction of breakfast buffets in two surgical wards. Adult patients had the opportunity to choose between an attractive breakfast buffet and regular bedside breakfast service. Primary outcomes were protein and energy intake during breakfast. We asked patients to report the type of breakfast service and breakfast intake in a diary over a seven-day period. Prognostic factors were used during multivariable regression analysis. RESULTS: A total of 77 patients were included. The median percentage of buffet use per patient during the seven-day study period was 50% (IQR 0-83). Mean protein intake was 14.7 g (SD 8.4) and mean energy intake 332.3 kcal (SD 156.9). Predictors for higher protein intake included the use of the breakfast buffet (ß = 0.06, p = 0.01) and patient weight (ß = 0.13, p = 0.01). Both use of the breakfast buffet (ß = 1.00, p = 0.02) and Delirium Observation Scale scores (ß = -246.29, p = 0.02) were related to higher energy intake. CONCLUSION: Introduction of a breakfast buffet on a surgical ward was associated with higher protein and energy intake and it could be a promising approach to optimizing such intake in surgical patients. Large, prospective and preferably randomized studies should confirm these findings.

The gap between rare and common cancers still exists: Results from a population-based study in the Netherlands.

INTRODUCTION: Epidemiological discrepancies exist between rare and common cancers. The aim of this population-based study was to compare rare versus common adult solid cancers in the Netherlands, by providing incidence, prevalence and survival rates, evaluating trends in survival and comparing individual entities within domains and families. METHODS: All adult patients with malignant solid cancers in the Netherlands between 1995 and 2019 were identified from the Netherlands Cancer Registry. Data on patient, tumour and treatment characteristics were collected, and relative survival and survival trends were analysed. RESULTS: A total of 170,628 patients with rare adult solid cancers and 806,023 patients with common adult solid cancers were included. Rare cancers accounted for 18% of all cancer diagnoses (mean incidence), and 15% of the total ten-year cancer prevalence during 2010-2019. Overall 5-year survival was worse for rare cancers than for common cancers (52.0% versus 68.7%). Between 1995-1999 and 2015-2019, 5-year survival rates for rare cancers increased to a lesser extent (from 46.2% to 52.6%, i.e. 6.4%) than for common cancers (56.9%-70.1%, i.e. 13.2%), and for most rare cancer domains compared to common cancer domains. The majority of rare cancer entities did not show an improvement in 5-year survival. Differences for individual entities between domains and families were found. CONCLUSION: Differences in survival between rare and common cancers indicate major challenges for rare cancer care and emphasise that improvement is highly needed. Observed inequalities need to be overcome by investing in early diagnosis, novel therapies, scientific research and in establishing centres of expertise.

Induction therapy with 177Lu-DOTATATE procures long-term survival in locally advanced or oligometastatic pancreatic neuroendocrine neoplasm patients.

PURPOSE: Peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE induces objective response in up to 57% of pancreatic neuroendocrine neoplasms (panNENs). Therefore, PRRT may comprise a downstaging option for panNEN patients who are not eligible for upfront curative surgery or are at high risk for recurrence. The aim of this study was to assess the potency of induction PRRT for locally advanced panNENs and to evaluate the effect of surgery after PRRT on overall survival (OS). METHODS: Retrospective cohort study of panNEN patients treated with induction 177Lu-DOTATATE. RESULTS: After PRRT, 26 out of 49 patients underwent pancreatic surgery with curative intent (PRRT + surgery). Partial objective response was obtained in 62% of the PRRT + surgery group versus 26% of the patients not undergoing panNEN surgery (PRRT-only group, p = 0.02). Downstaging in tumour-vessel interface was observed in 38% of all patients with at least one involved vessel. Median OS was 14.7 years (95% CI 5.9-23.6) for the PRRT + surgery group compared to 5.5 years (95% CI 4.5-6.5) for the PRRT-only group (p = 0.003). In the Cox proportional hazards analysis, surgery was not significantly associated with OS after propensity score adjustment with cumulative activity, performance status, tumour size after PRRT, and tumour grade. Median progression-free survival was 5.3 years (95% CI 2.4-8.1) for the PRRT + surgery group and 3.0 years (95% CI 1.6-4.4) for the PRRT-only group (p = 0.02). CONCLUSION: Early administration of PRRT followed by surgery is associated with favourable long-term outcomes in patients with locally advanced or oligometastatic panNEN and can be considered for selected patients with vascular involvement and/or increased risk of recurrence.

Health-Related Quality of Life in Adrenocortical Carcinoma: Development of the Disease-Specific Questionnaire ACC-QOL and Results from the PROFILES Registry.

We aimed to develop a disease-specific adrenocortical carcinoma (ACC) health-related quality of life (HRQoL) questionnaire (ACC-QOL) and assess HRQoL in a population-based cohort of patients with ACC. Development was in line with European Organization for Research and Treatment of Cancer (EORTC) guidelines, though not an EORTC product. In phase I and II, we identified 90 potential HRQoL issues using literature and focus groups, which were reduced to 39 by healthcare professionals. Pilot testing resulted in 28 questions, to be used alongside the EORTC QLQ-C30. In Phase III, 100 patients with ACC were asked to complete the questionnaires twice in the PROFILES registry (3-month interval, respondents: first 67, second 51). Confirmatory factor analysis demonstrated the structural validity of 26 questions with their scale structure (mitotane side-effects, hypercortisolism/hydrocortisone effects, emotional effects). Internal consistency and reliability were good (Cronbach's alpha 0.897, Interclass correlation coefficient 0.860). Responsiveness analysis showed good discriminative ability (AUC 0.788). Patients diagnosed more than 5 years ago reported a good HRQoL compared with the Dutch reference population, but experienced residual fatigue and emotional problems. Patients who underwent recent treatment reported a lower HRQoL and problems in several domains. In conclusion, we developed an ACC-specific HRQoL questionnaire with good psychometric properties.
