Despite the clear clinical significance of frailty in surgical populations, there is no consensus on how best to define or measure frailty, even within the geriatric literature. A diversity of measures exists to measure some or all these domains, but only research-focused tools have been validated in surgical populations. These tools are too resource-intensive for rapid, cost-effective, preoperative screening of entire populations considering elective surgery. This narrative review deals with the definition of frailty and the different assessment methods of the phenotypic definition and the accumulation of deficits definition. Moreover, as in the area of surgery frailty seems to be an independent risk factor for mortality, morbidity, length of stay, and postoperative complication, different studies reporting the association of preoperative frailty with postoperative outcomes after cancer surgery and the association with postoperative mortality within 30 days are considered. Preoperative care should include a focus on the goals of treatment and care options. Patient-oriented functional and cognitive outcomes as well as the development and implementation of interventions that could potentially improve adverse postoperative effects must be further investigated., (Copyright © 2023 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Introduction: Malnutrition is common in patients suffering from malignant diseases and has a major impact on patient outcomes. Prevention and early detection are crucial for effective treatment. This study aimed to investigate current international practice in the assessment and management of malnutrition in surgical oncology departments., Material and Methods: The survey was designed by European Society of Surgical Oncology (ESSO) and ESSO Young Surgeons and Alumni Club (EYSAC) Research Academy as an online questionnaire with 41 questions addressing three main areas: participant demographics, malnutrition assessment, and perioperative nutritional standards. The survey was distributed from October to November 2021 via emails, social media and the ESSO website to surgical networks focussing on surgical oncologists. Results were collected and analysed by an independent team., Results: A total of 156 participants from 39 different countries answered the survey, reflecting a response rate of 1.4%. Surgeons reported treating a mean of 22.4 patients per month. 38% of all patients treated in surgical oncology departments were routinely screened for malnutrition. 52% of patients were perceived as being at risk for malnutrition. The most used screening tool was the "Malnutrition Universal Screening Tool" (MUST). 68% of participants agreed that the surgeon is responsible for assessing preoperative nutritional status. 49% of patients were routinely seen by dieticians. In cases of severe malnutrition, 56% considered postponing the operation., Conclusions: The reported rate of malnutrition screening by surgical oncologists is lower than expected (38%). This indicates a need for improved awareness of malnutrition in surgical oncology, and nutritional screening., (Copyright © 2023 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Introduction: Multimodal treatment of patients with advanced pelvic malignancies (APM) is challenging and surgical expertise is usually concentrated in highly specialised centres. Given significant regional variation in APM surgery, surgical training represents a cornerstone in standardising and future-proofing of this complex therapy. The aim of this study was to describe the availability and current satisfaction levels with surgical training for APM., Material and Methods: An online questionnaire was developed and distributed through the Redcap© platform with 32 questions addressing participant and institution demographics, and training in APM surgeries. The survey was electronically disseminated in 2021 to surgical networks across Europe including all specialities treating APM via the European Society of Surgical Oncology (ESSO). All statistical analysis were performed using R., Results: The survey received 280 responses from surgeons across 49 countries, representing general surgery (36%), surgical oncology (30%), gynaeoncology (15%), colorectal surgery (14%) and urology (5%). Fifty-three percent of participants report performing >25 APM procedures/year. Respondents were departmental chiefs (12%), consultants (34%), specialist surgeons (40%) and fellows (15%). 34% were happy/very happy with their training with 70% satisfaction about their exposure to surgical procedures. Respondents reported a lack of standardised training (72%), monitoring tools (41%) and mentorship (56%). 57% rated attended courses as useful for training, while 80% rated visiting expert centres as useful., Conclusion: This study has identified a learning need for improved structured training in APM, with low current satisfaction levels with exposure to APM training. Organisations such as ESSO provide an important platform for visiting expert centres, courses, and structured training., Competing Interests: Declaration of competing interest Andreas Brandl, Dara Lundon, Laura Lorenzon, Yvonne Schrage, Carmela Caballero, Carl Jacob Holmberg, Nada Santrac, Mariela Vasileva-Slaveva, Giacomo Montagna, Olivia Sgarbura, Raza Sayyed, Almog Ben-Yaacov, Johnn Henry Herrera Kok, Ina Suppan, Helen Mohan, Wim Ceelen, Tibor Kovacs, Domenico D'Ugo, Sergio Sandrucci declared that they have no conflict of interest., (Copyright © 2022 The Authors.

Introduction: Surgical oncology is a defined specialty within the European Board of Surgery within the European Union of Medical Specialists (UEMS). Variation in training and specialization still occurs across Europe. There is a need to align the core knowledge needed to fulfil the criteria across subspecialities in surgical oncology., Material and Methods: The core curriculum, established in 2013, was developed with contributions from expert advisors from within the European Society of Surgical Oncology (ESSO), European Society for Radiotherapy and Oncology (ESTRO) and European Society of Medical Oncology (ESMO) and related subspeciality experts., Results: The current version reiterates and updates the core curriculum structure needed for current and future candidates who plans to train for and eventually sit the European fellowship exam for the European Board of Surgery in Surgical Oncology. The content included is not intended to be exhaustive but, rather to give the candidate an idea of expectations and areas for in depth study, in addition to the practical requirements. The five elements included are: Basic principles of oncology; Disease site specific oncology; Generic clinical skills; Training recommendations, and, lastly; Eligibility for the EBSQ exam in Surgical Oncology., Conclusions: As evidence-based care for cancer patients evolves through research into basic science, translational research and clinical trials, the core curriculum will evolve, mature and adapt to deliver continual improvements in cancer outcomes for patients., Competing Interests: Declaration of Competing Interest There are no conflicts of interest reported., (Copyright © 2021 The Authors.

Introduction: The majority of cancer patients report malnutrition, with a significant impact on patient's outcome. This study aimed to compare how nutritional assessment is conducted across different surgical oncology sub-specialties., Methods: Survey modules were designed for breast, hepato-pancreato-biliary (HPB), upper-gastrointestinal (UGI), sarcoma, peritoneal and surface malignancies (PSM) and colorectal cancer (CRC) surgeries to describe 4 domains: participants' setting, evaluation of clinical factors, use of screening tools and clinical practice. Results were compared among sub-specialties and according to human development index (HDI) in the largest cohorts., Results: Out of 457 answers from 377 global participants (62% European), 35.0% were from breast and 28.9% were from CRC surgeons. Although MDTs management is consistently reported (64-88%), the presence of a nutritionist/dietician ranges from 14.1% to 44.2%. Breast surgeons seldom evaluate albumin (25.6%) and weight loss (30.6%), opposite to HPB, PSM and UGI groups (>70%, p 0.044). Overall, responders declared that the use of screening tools is largely neglected, that nutritional status is often assessed by the surgeons and that nutrition is not consistently modified according to risk factors (range among groups respectively: 1.9%-25.6%, 33.1%-51.4%, 33.1%-60.5%). Less than 20% of breast surgeons assess patients before/after surgery, comparing to >60% of PSM surgeons. However, no statistical differences were documented comparing groups for the majority of the items of the 4 domains. Nutritional evaluation is more often conducted by breast surgeons in medium/low HDI countries comparing very high/high HDI (p 0.04)., Conclusions: Nutritional assessment is largely neglected. These results identify target-issues for the implementation of clinical practice., Competing Interests: Declaration of competing interest None of the authors has any potential financial conflict of interest related to this manuscript., (Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

There are several suggestions that centralization of care improves outcome for rare cancers, particularly when optimal treatment requires complex surgery or high-technology radiotherapy equipment. Diagnosis and treatment in reference centers are expected to be more accurate because they benefit from large numbers of cases discussed in a multidisciplinary tumor board with a well-run pathway. However, centralization is sometimes moderately perceived by oncologists as a solution to be endorsed for rare cancer patients; disadvantages of centralization are the need for patients to move and the risk of a longer waiting list, with discomfort and possible negative effects on outcome. It is difficult to find single experts on rare cancers: all the more it will be difficult to find a multidisciplinary panel of experts, and the role of the surgeon is to be a functional part of it. On the other side, from a surgical point of view, the quality of the initial management of many rare cancers directly impacts the final outcome; surgery of rare cancers may not necessarily be more demanding than the average from a technical point of view, but the lack of cultural knowledge about the disease can well lead to inappropriateness even in the lack of major technical challenges. Care for rare cancer patients must be organized in pathways that cover the patient's journey from their point of view rather than that of the healthcare system, and pathways must follow the best evidence on diagnosis, treatment and follow-up., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Malnutrition in cancer patients - in both prevalence and degree - depends primarily on tumor stage and site. Preoperative malnutrition in surgical patients is a frequent problem and is associated with prolonged hospital stay, a higher rate of postoperative complications, higher re-admission rates, and a higher incidence of postoperative death. Given the focus on the cancer and its cure, nutrition is often neglected or under-evaluated, and this despite the availability of international guidelines for nutritional care in cancer patients and the evidence that nutritional deterioration negatively affects survival. Inadequate nutritional support for cancer patients should be considered ethically unacceptable; prompt nutritional support must be guaranteed to all cancer patients, as it can have many clinical and economic advantages. Patients undergoing multimodal oncological care are at particular risk of progressive nutritional decline, and it is essential to minimize the nutritional/metabolic impact of oncological treatments and to manage each surgical episode within the context of an enhanced recovery pathway. In Europe, enhanced recovery after surgery (ERAS) and routine nutritional assessment are only partially implemented because of insufficient awareness among health professionals of nutritional problems, a lack of structured collaboration between surgeons and clinical nutrition specialists, old dogmas, and the absence of dedicated resources. Collaboration between opinion leaders dedicated to ERAS from both the European Society of Surgical Oncology (ESSO) and the ERAS Society was born with the aim of promoting nutritional assessment and perioperative nutrition with and without an enhanced recovery program. The goal will be to improve awareness in the surgical oncology community and at institutional level to modify current clinical practice and identify optimal treatment options., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Aim: To evaluate the "state of art" of clinical role of sentinel lymph node (SLN) biopsy procedure in patients affected by differentiated thyroid carcinoma., Methods: All papers cited on PubMed/MEDLINE until June 2005, published in English, and referred to the key words "sentinel lymph node biopsy" AND "thyroid carcinoma" OR "thyroid cancer" were reviewed for the purpose of the present study., Results: The first method used for SLN biopsy in thyroid carcinoma patients was the vital blue dye technique. This technique had some disadvantages as: (a) risk of disruption of the lymphatic channels deriving from the thyroid cancer; (b) difficulty in disclosing SLN lying outside the central compartment; (c) parathyroid glands can take up blue dye and, thus, can be misinterpreted as lymph nodes. Some of the above cited disadvantages were overcome by using the lymphoscintigraphy and intraoperative gamma probe technique. A combination of the blue dye and gamma probe technique has also been proposed with synergic results., Conclusion: The reported advantages of the SLN biopsy in small differentiated thyroid carcinoma patients can be resumed as follows: (a) better selection of patients who would benefit from compartment oriented nodal dissection; (b) more accurate lymph node staging; (c) better selection of patients who can require (131)I treatment after surgery (SLN positive for metastasis); (d) better identification of SLN located out of the central compartment.
