Radiomic Gradient in Peritumoural Tissue of Liver Metastases: A Biomarker for Clinical Practice? Analysing Density, Entropy, and Uniformity Variations with Distance from the Tumour.

The radiomic analysis of the tissue surrounding colorectal liver metastases (CRLM) enhances the prediction accuracy of pathology data and survival. We explored the variation of the textural features in the peritumoural tissue as the distance from CRLM increases. We considered patients with hypodense CRLMs >10 mm and high-quality computed tomography (CT). In the portal phase, we segmented (1) the tumour, (2) a series of concentric rims at a progressively increasing distance from CRLM (from one to ten millimetres), and (3) a cylinder of normal parenchyma (Liver-VOI). Sixty-three CRLMs in 51 patients were analysed. Median peritumoural HU values were similar to Liver-VOI, except for the first millimetre around the CRLM. Entropy progressively decreased (from 3.11 of CRLM to 2.54 of Liver-VOI), while uniformity increased (from 0.135 to 0.199, p < 0.001). At 10 mm from CRLM, entropy was similar to the Liver-VOI in 62% of cases and uniformity in 46%. In small CRLMs (≤30 mm) and responders to chemotherapy, normalisation of entropy and uniformity values occurred in a higher proportion of cases and at a shorter distance. The radiomic analysis of the parenchyma surrounding CRLMs unveiled a wide halo of progressively decreasing entropy and increasing uniformity despite a normal radiological aspect. Underlying pathology data should be investigated.

Metastatic presentation of dermatofibrosarcoma protuberans as massive lower gastrointestinal bleed.

Dermatofibrosarcoma protuberans (DFSP) is an aggressive tumour with multiple local recurrences and rare metastatic potential. Fibrosarcomatous transformation occurs in a few cases of DFSP which makes them more aggressive in terms of recurrence and metastasis. Here we report the case of a woman in her late 30s who presented with massive lower gastrointestinal (GI) bleeding with a history of multiple surgeries for DFSP on her anterior abdominal wall. The bleeding source was identified to be a mass lesion in the jejunum, which was excised. The patient recovered well and the histopathology revealed fibrosarcoma of the jejunum. Follow-up investigations showed multiple lung nodules, ascites and abdominal lymph nodes suggesting progressive disease. She is currently receiving chemotherapy and progressing well 3 months postoperatively. Patients with fibrosarcomatous changes within DFSP must be followed up closely as it is associated with increased metastatic potential.

Survival benefit associated with screening of patients at elevated risk for pancreatic cancer.

BACKGROUND & OBJECTIVES: Screening for pancreatic cancer is recommended for individuals with a strong family history, certain genetic syndromes, or a neoplastic cyst of the pancreas. However, limited data supports a survival benefit attributable to screening these higher-risk individuals. METHODS: All patients enrolled in screening at a High-Risk Pancreatic Cancer Clinic (HRC) from July 2013 to June 2020 were identified from a prospectively maintained institutional database and compared to patients evaluated at a Surgical Oncology Clinic (SOC) at the same institution during the same period. Clinical outcomes of patients selected for surgical resection, particularly clinicopathologic stage and overall survival, were compared. RESULTS: Among 826 HRC patients followed for a median (IQR) of 2.3 (0.8-4.2) years, 128 were selected for surgical resection and compared to 402 SOC patients selected for resection. Overall survival was significantly longer among HRC patients (median survival: not reached vs. 2.6 years, p < 0.001). Among 31 HRC and 217 SOC patients with a diagnosis of pancreatic ductal adenocarcinoma (PDAC), the majority of HRC patients were diagnosed with stage 0 disease (carcinoma in situ), while the majority of SOC patients were diagnosed with stage II disease (p < 0.001). Overall survival after resection of invasive PDAC was also significantly longer among HRC patients compared to SOC patients (median survival 5.5 vs. 1.6 years, p = 0.002). CONCLUSION: Patients at increased risk for PDAC and followed with guideline-based screening exhibited downstaging of disease and improved survival from PDAC in comparison to patients who were not screened.

Molecular classification of endometrial carcinoma on endometrial biopsy: an early prognostic value to guide personalized treatment.

OBJECTIVE: Molecular features are essential for estimating the risk of recurrence and impacting overall survival in patients with endometrial cancer. Additionally, the surgical procedure itself could be personalized based on the molecular characteristics of the tumor. This study aims to assess the feasibility of obtaining reliable molecular classification status from biopsy specimens collected during hysteroscopy to better modulate the appropriate surgical treatment. METHODS: This monocentric, retrospective, observational study was conducted on 106 patients who underwent a biopsy procedure followed by radical surgery for endometrial cancer, with concurrent molecular investigation. The molecular classification was determined through immunohistochemical staining for p53 and mismatch repair proteins, along with gene sequencing for POLE. RESULTS: Overall, 106 patients underwent molecular investigation, which was finally achieved on 99 patients (93.4%). Among these, the molecular analysis was conducted in 71 patients (67%) on the pre-operative endometrial biopsy and on the final uterine specimen in 28 patients (26.4%). Most of the endometrial biopsies were performed using Bettocchi hysteroscopy (66%). Molecular analysis was not possible in seven patients (6.6%), with six cases due to sample inadequacy and one case attributed to intra-mucosal carcinoma. The molecular results showed that the copy number low sub-group was the most common, and five cases of 'multiple classifiers' were observed in the low-risk category. CONCLUSION: Our experience in obtaining molecular information from biopsy samples underscores the feasibility and efficacy of this technique, even in small tissue samples. This capability helps define the prognostic group of patients, facilitates timely decision-making, and develops a personalized strategy for each patient.

Use of social media for academic and professional purposes by gynecologic oncologists.

OBJECTIVE: To investigate the prevalence and patterns of social media use among gynecologic oncologists for professional and academic purposes. METHODS: A prospective online survey between November and December 2022 targeted gynecologic oncology practitioners (gynecologic oncologists, surgical oncologists, medical oncologists, radiation/clinical oncologists, and onco-pathologists/pathologists). The survey, distributed via various social media platforms, included 40 questions to capture qualitative and quantitative data on social media use. RESULTS: Of 131 respondents from 32 countries, 106 (80.9%) were gynecologic oncologists and affiliated with academic institutions (84.7%). Facebook (n=110, 83.9%), Twitter (n= 108, 82.4%), and Instagram (n=100, 76.3%) were the most used platforms. Respondents used social media to stay updated (n=101, 77.1%), network (n=97, 74%), learn about conferences and webinars (n=97, 74%), and engage in academic discussions (n=84, 64.1%). Following the COVID-19 pandemic, 100/129 (77.5%) reported increased social media use. However, only 32 (24.4%) used it to connect with patients, and concerns were raised about privacy and the need for separate professional and personal accounts. A quarter of respondents hesitated to share their opinions on social media due to the fear of controversy, with 26 (20%) experiencing cyberbullying, yet 120/130 (92.3%) believed it enabled junior professionals to express their views. Concerns about differentiating valid content, information reliability, and the professional perception of sourcing knowledge from social media were noted. Gender, age, specialty, and income level influenced patterns of social media use, with variations in preferences for platforms, content engagement, and purposes, highlighting a complex landscape of social media interaction among gynecologic oncologists. CONCLUSION: While the use of social media among gynecologic oncologists is prevalent, particularly for academic and professional development, challenges such as cyberbullying, privacy concerns, and the need for formal training in social media navigation persist. Tailored training programs and guidelines could enhance social media's effective and ethical use in this field, promoting a safe environment for professional expression and engagement.

Extramammary breast cancer of the vulva.

A woman in her 70s was seen in the gynaecology outpatient clinic with a swelling on the right side of the vulva. Surgical excision of the lesion revealed unexpectedly an extensive ductal carcinoma in situ with a focus of a grade 2 invasive ductal carcinoma arising in extramammary breast tissue of the vulva. Postoperative staging studies showed normal breasts, with no evidence of disease elsewhere. The patient underwent a wider excision of the right vulva and sentinel node biopsy of the right inguinal region, which revealed no further disease. The patient is currently taking adjuvant hormonal therapy and has remained disease free at 2-year follow-up. This case underscores the importance of considering rare presentations of vulvar malignancies and the necessity for a multidisciplinary approach in managing such cases.

The role of a dedicated Oncology Nurse Navigator in the surgical oncology pathways: 1 year experience from a General Surgery Unit in central Italy with follow up.

The Nurse Navigator is a highly specialized nurse with technical and non-technical skills that offers individualized assistance to cancer patients, their family and caregivers to overcome health system barriers and facilitate access to care. This role was introduced in the General Surgery Unit of the Madonna del Soccorso Hospital in San Benedetto del Tronto from 1st January 2023. The primary endpoint is to compare the times taken for each step of the diagnostic-therapeutic pathway comparing the study group followed by Oncology Nurse Navigator (ONN) and the group not followed by this role. The secondary endpoints, only for the study group, were the number of patient contacts with the ONN and the time slots; the number of examinations and consultations organized by ONN; the evaluation of patient satisfaction at discharge; the number and type of problems noted during follow-up contact at 7 and 30 days after discharge. A prospective court study with historical control was conducted from 1st January 2023 in Madonna del Soccorso Hospital, Italy. The study group consists of all cancer patients cared for by ONN. The control group was created by selecting the same number of patients as the study group but taken care of in the previous 3 years (from 2020 to 2022) and, therefore, without the presence of the Nurse Navigator. The control group data come from clinical documentation. The number and time slots of contact with the ONN were recorded through the use of a company mobile phone active 24/7 through phone calls and messages. The number of examinations and consultations is known through online requests. The satisfaction assessment was carried out through the use of externally validated questionnaire Patient Satisfaction with Cancer Care (PSCC). The follow-up was performed by telephone and recorded on documentation according to established parameters. A total of 200 patients were analyzed. Both the study and control groups included 100 patients each. The average time between the first contact with the patient and the execution of the diagnostic test was 7 days in the cases compared to 28 days in the control group. The waiting time for the Multi-Disciplinary Team discussion (MDT) was 3 days for the study group compared to 6 days in the control group. The average time taken for the first oncological visit was 3 days in the study group compared to 18 days in the controls. The time from first contact to the operating session was 20 days compared to 45 in controls. Each patient had an average of 10 phone calls with the ONN. For all patients accompanied at the first diagnosis, at least 2 radiological and laboratory tests were organized. Oncology appointment for treatment evaluations after delivery of the histological report was communicated within a maximum of 3 working days. A patient satisfaction questionnaire achieved a response rate of 100%, with an average score of 87.0/90. The telephone follow-up had a response rate of 100% of patients and revealed a decrease in problems at the 30-day check-up compared to that of 7 days after discharge. (Activity of Daily Living 20% vs 8%; nutritional problems 40% vs 21%, pain 18% vs 2%; surgical wounds 45% vs 1%; mobilization 8% vs 0%). The data demonstrate that ONN service improves the quality and outcomes of surgical oncology patients' pathway. The professional role of the ONN, with predefined technical and non-technical skills, should also be officially recognized by the healthcare system and hospital administration.

Total pelvic exenteration extended to pelvic bones with subsequent VRAM flap reconstruction in patient with recurrent anal squamous cell carcinoma following chemoradiotherapy.

Anal squamous cell carcinoma, typically associated with human papillomavirus infection, remains a rare malignancy. This article outlines a case of local recurrence in a male patient with a history of HIV and hepatitis C virus infection, previously treated with chemoradiotherapy. Extensive tumour involvement called for total pelvic exenteration extended to anterior osteomuscular compartment and genitalia. The surgical approach involved multidisciplinary collaboration and detailed preoperative planning using three-dimensional reconstruction. Key surgical considerations comprised the following: achieving tumour-free margins (R0 resection), extensive osteotomies and intricate pelvic floor reconstruction with prosthetic mesh and flap reconstruction. The procedure successfully yielded an R0 resection, maintaining adequate lower limb functionality. Our case report underscores the benefits of pelvic exenteration in locally advanced or recurrent pelvic tumours, invariably following careful patient selection and exhaustive preoperative studies.

Adult granulosa cell tumour camouflaged as mucinous neoplasm.

This case report delves into the diagnostic intricacies and clinical management of adult granulosa cell tumour (AGCT) in a woman in her 50s, presenting with pain abdomen. Initial imaging investigations like ultrasound suggested diagnosis of benign cystadenoma. Further MRI revealed a large well-defined multiloculated lesion so a diagnosis of neoplastic aetiology/likely mucinous cystadenocarcinoma was offered. However, the definitive diagnosis was established through meticulous histopathological examination, revealing characteristic features of AGCT, a rare ovarian neoplasm. The case underscores the diagnostic challenges posed by AGCT, the importance of integrating clinical, radiological and histopathological data, and the necessity for a multidisciplinary approach for accurate diagnosis and optimal patient management.

Uterine Transposition.

In this video, we review the steps of uterine transposition, emphasizing robotic trocar placement and docking, how to optimize organ manipulation and tissue handling, and our pearls for successful perioperative management. The patient is a 27-year-old woman with T2 node-positive rectal cancer. Uterine transposition is a new surgical procedure with limited information regarding outcomes. Although evolving over time, we present our preferred patient selection criteria and identify key stakeholders, which include colorectal surgeons, radiation oncologists, fertility specialists, social workers, and radiologists.

Small duct and large duct type intrahepatic cholangiocarcinoma reveal distinct patterns of immune signatures.

PURPOSE: Dedicated gene signatures in small (SD-iCCA) and large (LD-iCCA) duct type intrahepatic cholangiocarcinoma remain unknown. We performed immune profiling in SD- and LD-iCCA to identify novel biomarker candidates for personalized medicine. METHODS: Retrospectively, 19 iCCA patients with either SD-iCCA (n = 10, median age, 63.1 years (45-86); men, 4) or LD-iCCA (n = 9, median age, 69.7 years (62-85); men, 5)) were included. All patients were diagnosed and histologically confirmed between 04/2009 and 01/2021. Tumor tissue samples were processed for differential expression profiling using NanoString nCounter® PanCancer Immune Profiling Panel. RESULTS: With the exception of complement signatures, immune-related pathways were broadly downregulated in SD-iCCA vs. LD-iCCA. A total of 20 immune-related genes were strongly downregulated in SD-iCCA with DMBT1 (log2fc = -5.39, p = 0.01) and CEACAM6 (log2fc = -6.38, p = 0.01) showing the strongest downregulation. Among 7 strongly (log2fc > 2, p ≤ 0.02) upregulated genes, CRP (log2fc = 5.06, p = 0.02) ranked first, and four others were associated with complement (C5, C4BPA, C8A, C8B). Total tumor-infiltrating lymphocytes (TIL) signature was decreased in SD-iCCA with elevated ratios of exhausted-CD8/TILs, NK/TILs, and cytotoxic cells/TILs while having decreased ratios of B-cells/TILs, mast cells/TILs and dendritic cells/TILs. The immune profiling signatures in SD-iCCA revealed downregulation in chemokine signaling pathways inclulding JAK2/3 and ERK1/2 as well as nearly all cytokine-cytokine receptor interaction pathways with the exception of the CXCL1/CXCR1-axis. CONCLUSION: Immune patterns differed in SD-iCCA versus LD-iCCA. We identified potential biomarker candidate genes, including CRP, CEACAM6, DMBT1, and various complement factors that could be explored for augmented diagnostics and treatment decision-making.

Surgical management of pancreatic neuroendocrine tumors - An EYSAC and E-AHPBA international survey of current practice.

INTRODUCTION: Pancreatic neuroendocrine tumors (pNET) exhibit a wide spectrum of clinical behavior, which makes their assessment and management quite challenging. The purpose of this study was to comprehensively assess the existing treatment landscape for patients with pNET. MATERIALS AND METHODS: The study was conducted with the support of the ESSO-EYSAC Research Academy in collaboration with the E-AHPBA. An online survey was distributed via email and social media to surgical networks across Europe and beyond (September 1-30, 2023). RESULTS: Overall, 155 complete responses were obtained. A specialized NET tumor board was present at the institutions of 94 (61 %) of the study participants. The most frequently applied guidelines were from ENETS (n = 97; 63 %), NCCN (n = 74; 48 %), and ESMO (n = 53; 34 %). For resectability, similar criteria as in pancreatic ductal adenocarcinoma were used by 111 (72 %) participants, even though 116 (75 %) participants believed that pNET/pNEC should have their own resectability criteria. Most respondents used somatostatin analogues (n = 126; 81 %) and chemotherapy (n = 85; 55 %) as neoadjuvant treatments, followed by molecularly targeted agents (n = 45; 29 %) and PRRT (n = 37; 24 %). Only 17 (11 %) participants agreed/strongly agreed that the management of pNET/pNEC is sufficiently addressed in surgical education programs. CONCLUSION: This international survey highlighted areas for improvement in the care of pNET, namely the lack of pNET-specific resectability criteria and educational programs addressing pNET management.

Metastatic benign leiomyoma: A case report of an uncommon presentation.

Uterine leiomyoma is a benign tumor of myometrial tissue which usually affects women of reproductive age. Its prevalence increases with age and has a peak incidence at the age of 40. Metastasizing leiomyomas are dense connective tissue and smooth myometrial muscle cells tumors located outside the uterus. We present the case report of a 55-year-old female referred to investigate pulmonary nodules with the diagnosis of metastasizing leiomyoma.

LAMN port-site metastasis after laparoscopic oophorectomy for a presumed ovarian tumour treated with CRS and HIPEC.

Low-grade appendiceal mucinous neoplasm (LAMN) may culminate as a mucin-secreting disease known as pseudomyxoma peritonei (PMP). Once the diagnosis of LAMN and PMP is made, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC) are indicated.Herein, we present a female patient in her 50s who was diagnosed with an ovarian mass for which she underwent laparoscopic oophorectomy. As the pathology of the ovary showed a tumour of gastrointestinal origin, she then underwent CRS and HIPEC with a final pathology of LAMN. Six weeks later, a mucinous lesion confined to the abdominal wall was detected on a postoperative CT. Suspected for port-site metastasis at the laparoscopic trocar site, we treated this lesion using the same principles of treatment as the intra-abdominal disease. The abdominal wall mass was surgically resected, and the cavity created was irrigated with mitomycin C. On 30 months of follow-up, the patient had no evidence of disease.

Complete response to chemotherapy in a 6-year survivor of metastatic pancreatic cancer.

A woman in her 40s underwent evaluation for abdominal pain, jaundice and acholic stools and was diagnosed with metastatic pancreatic head adenocarcinoma. She was enrolled in a clinical trial investigating the benefits of ibrutinib with nab-paclitaxel and gemcitabine, and subsequently received modified FOLFIRINOX. Over the course of 6 years on chemotherapy, she experienced complete regression of the pancreatic and liver lesions, as well as normalisation of her tumour markers. She has been off chemotherapy for 6 months with no evidence of disease and normal tumour markers. Despite advances in chemotherapy and surgical options, metastatic pancreatic adenocarcinoma continues to carry a grim prognosis. This case report demonstrates a rare case of a long-term survivor of unresectable metastatic pancreatic adenocarcinoma treated with chemotherapy alone.

Indwelling-tunneled-central-venous-catheter-related early bacteremia and preoperative prophylaxis: a case and control study. / Bacteriemia precoz asociada a catéter venoso central tunelizado permanente y profilaxis preoperatoria: estudio de casos y controles.

INTRODUCTION: The indication of preoperative prophylaxis in the insertion of indwelling tunneled central venous catheters (ITCVC) has a low level of evidence. Our objective was to assess risk factors of ITCVC-related early bacteremia in oncological pediatric patients and to determine the need for preoperative prophylaxis. MATERIALS AND METHODS: A univariate and multivariate retrospective analysis of patients in whom an ITCVC was placed from January 2020 to July 2023, according to whether they had ITCVC-related early bacteremia (EB) in the first 30 postoperative days, was carried out. Demographic variables, leukopenia, neutropenia, use of preoperative antibiotic prophylaxis, and history of central venous catheter (CVC) or bacteremia were collected. Calculations were carried out using the IBM SSPS29® software. RESULTS: 176 patients with a mean age of 7.6 years (SD: 4.82) were analyzed. 7 EB cases were identified, with a greater frequency of neutropenia (p= 0.2), history of CVC in the 48 hours before insertion (p= 0.08), and intraoperative CVC (p= 0.04). The presence of intraoperative CVC increased the risk of EB 9-fold [OR: 9.4 (95%CI: 1.288-69.712) (p= 0.027)]. The lack of preoperative prophylaxis did not increase the risk of EB [OR: 2.2 (CI: 0.383-12.669) (p= 0.3)]. The association with other variables was not significant. CONCLUSIONS: The intraoperative presence of CVC was a risk factor of EB in our patients. Preoperative prophylaxis had no impact on the risk of EB, which in our view does not support its use. However, further studies with a larger sample size are required. Leukopenia or neutropenia at diagnosis were not associated with a greater prevalence of infection.

INTRODUCCION: La indicación de profilaxis preoperatoria en la colocación de catéteres venosos centrales tunelizados permanentes (CVCTP) tiene bajo nivel de evidencia. Nuestro objetivo fue evaluar factores de riesgo de bacteriemia precoz asociada a CVCTP en pacientes pediátricos oncológicos y determinar la necesidad de profilaxis preoperatoria. MATERIAL Y METODOS: Realizamos un análisis retrospectivo univariante y multivariante de los pacientes con colocación de CVCTP entre enero 2020 y julio 2023, en función de si presentaron bacteriemia precoz (BP) relacionada con CVCTP en los primeros 30 días postoperatorios. Recogimos variables demográficas y otras como: leucopenia, neutropenia, uso de profilaxis antibiótica preoperatoria y antecedente de catéter venoso central (CVC) o bacteriemia. Los cálculos se realizaron mediante el software IBM SSPS29®. RESULTADOS: Analizamos 176 pacientes, con edad media de 7,6 años (SD 4,82). Identificamos 7 casos de BP, que presentaron mayor frecuencia de neutropenia (p=  0,2) y antecedente de CVC las 48h previas a la colocación (p=  0,08) y CVC intraoperatorio (p=  0,04). La presencia de CVC intraoperatorio aumentó 9 veces el riesgo de BP [OR 9,4 (IC 95% de 1,288-69,712) (p=  0,027)]. La falta de profilaxis prequirúrgica no aumentó el riesgo de BP [OR 2,2 (IC 0,383-12,669) (p=  0,3)]. La relación con otras variables no fue significativa. CONCLUSIONES: La presencia intraoperatoria de CVC fue factor de riesgo de BP en nuestros pacientes. La profilaxis preoperatoria no influyó sobre el riesgo de BP, por lo que creemos que su empleo no está justificado, aunque se necesitarían más estudios con mayor tamaño muestral. La leucopenia o neutropenia al momento diagnóstico no se relacionaron con mayor prevalencia de infección.

Current surgical practice for central venous access to deliver chemotherapy and enteral access for nutritional support in pediatric patients with an oncological diagnosis.

Central venous access through tunneled central venous catheters (CVCs) are one of the cornerstones of modern oncologic practice in pediatric patients since CVCs provide a reliable access route for the administration of chemotherapy. Establishing best practices for CVC management in children with cancer is essential to optimize care. This article reviews current best practices, including types of devices, their placement, complications, and long-term outcomes. Additionally, nutrition status and nutritional support are also very important determinants of outcomes and care in pediatric surgical oncology patients. We review current nutritional assessment, support, access for enteral and parenteral nutrition delivery, and their complications, mainly from a surgical perspective. Overall, access surgery, whether for CVCs, or for enteral access can be challenging, and best practice guidelines supported by current though limited evidence are necessary to minimize complications and optimize outcomes.

Robotic-assisted laparoscopic resection of a pelvic solitary fibrous tumour causing distal ureteric compression.

This case report describes a male in his late 40s with a 4 cm pelvic mass compressing the left distal ureter, resulting in left hydroureteronephrosis. Biopsy of the mass was suggestive of a solitary fibrous tumour. The patient underwent a robotic-assisted laparoscopic excision of the left pelvic mass. Intraoperatively, the mass was found to be densely adhered to the ureter, necessitating a left distal ureterectomy and ureteric reimplantation. Subsequent histopathological analysis revealed the mass was a solitary fibrous tumour with no evidence of malignancy.
