Background/Objectives: Pelvic exenteration (PE) might be a curative option for patients with advanced pelvic malignancies. Due to its significant morbidity and mortality rates, PE necessitates meticulous patient selection, and a comprehensive understanding of disease spread. This study outlines the experience at a single tertiary referral center and investigates prognostic factors influencing survival post-PE, thereby guiding clinical decision-making processes. Methods: Patients undergoing PE for advanced pelvic gynecological malignancies between 01/2016 and 12/2023 were retrospectively analyzed using a prospectively managed database. Eligibility for PE was determined through individualized tumor board evaluations based on CT/MRI imaging, excluding patients with distant metastases. Baseline demographic and clinical characteristics, operative details, complication rates, and histopathological findings were assessed using univariate and multivariate regression analyses. Disease-free (DFS) and overall survival (OS) were assessed by Kaplan-Meier analysis. Poor outcome prognostic factors were identified, outlining an optimal candidate profile for PE. Results: A total of 70 patients were included. The median age was 54.5 years. Forty-three patients (61.4%) presented with recurrent disease and the majority were diagnosed with cervical cancer (n = 48, 68.6%). Total PE was performed in 40 patients (57.1%), with complete tumor resection achieved in 68.6% of patients (n = 48). Sixteen patients (22.8%) experienced grade IV/V complications. Median DFS and OS were 8.2 and 16.4 months, respectively. Multivariate analysis identified R1 resection status and para-aortic lymph node involvement as independent negative prognostic factors. Conclusions: PE is a viable option for selected patients with advanced primary and recurrent pelvic gynecological malignancies. When complete tumor resection is feasible, patients may derive benefit from PE, although the risk of severe perioperative complications must be carefully evaluated. Full article

Objectives: Despite the relatively high incidence of vulvar cancer, there is a noticeable lack of studies in Romania and other Eastern European countries focused on evaluating the long-term oncological outcomes and Quality of Life (QoL) for patients with this condition. Methods: A total of 91 patients were included in the study. The first objective was to evaluate the 5-year overall survival (OS) in patients with vulvar cancer at International Federation of Gynecology and Obstetrics (FIGO) stages IA-IVA who underwent surgery, ±adjuvant radiotherapy (RT). Additionally, the study aimed to identify prognostic factors that could either positively or negatively influence survival outcomes in these patients. The second objective was to assess the QoL, conducted using validated questionnaires issued by the European Organization for Research and Treatment of Cancer, specifically the QLQ-CX30 and QLQ-VU34. Results: The patients had an average age of 67.7 years (38–91). At the time of assessment, 51.6% of the patients were alive. Additionally, the 5-year OS was reported at 45%. The multivariate analysis indicated that age ≤ 50 years (p < 0.03), FIGO stage IB (p < 0.007), and tumor differentiation grade I (p < 0.01) were associated with improved survival rates. Conversely, age > 80 years (p < 0.05), FIGO stages IIIB (p < 0.01) and IIIC (p < 0.06), tumor size > 5 cm (p < 0.02), positive resection margins (p < 0.03), lymph node metastasis (p < 0.06), and pelvic exenteration (p < 0.002) were identified as independent negative prognostic factors. Of the 47 living patients, 32 completed the QoL questionnaires. The respondents reported a decent overall QoL score of 65.3. However, treatment-specific symptoms, such as vulvar scarring, vulvar swelling, groin lymphedema, and leg lymphedema, had a negative impact on QoL. Consequently, functional symptoms like fatigue, pain, and sleep disturbances persisted, leading to a body image perception score of 33.7 on a scale from 0 to 100. Conclusions: This study highlights decent OS and QoL outcomes. It is important to note that vulvar cancer primarily affects older women. In this study, 51.6% of patients were over 70 years old at the time of surgery. Consequently, the 5-year OS of 45% could not be attributed solely to oncological factors, as most of these patients did not die from recurrences but rather from associated comorbidities. The findings of this study provide a foundation for future randomized controlled trials aimed at further enhancing vulvar cancer patients’ care and outcomes. Full article

Background and Objectives: Robotic surgery represents one of the most significant innovations in the field of surgery, offering new opportunities for the treatment of complex pathologies that require greater accuracy and precision. It is a technology that has become widely used in general, urologic, gynecologic, and cardio-thoracic surgery, but has a limited evidence in the head and neck region. This review explores the use of robotic surgery in orbital pathology, focusing on its applications, benefits, and limitations. Materials and Methods: A cross-sectional search method was performed in multiple databases to answer the following question: “What are the applications of robotic surgery in the management of orbital pathologies?” Studies were carefully reviewed by two simultaneous researchers, and, in case of disagreement, a third researcher was engaged. Care was taken to identify the surgical hardware (robotic station) used to perform the surgical procedure. Results: Out of 491 records, eight studies met the inclusion criteria. These included cadaveric, preclinical, in vitro, and early clinical investigations assessing robotic approaches for fronto-orbital advancement, tumor resection, orbital decompression, and other surgical procedures such as lacrimal gland dissection and biopsy, medial and lateral orbital wall dissections, enucleation, and lid-sparing orbital exenteration. The robotic systems evaluated included the Da Vinci Xi, Da Vinci SP, Medineering Robotic Endoscope Guiding System, and a modular multi-arm concentric tube robot, each with specific advantages and limitations. Conclusions: Robotic surgery provides significant advantages for orbital pathologies such as improved precision, visualization, and tissue preservation, with reduced complications and faster recovery, although some limitations still exist. Future advancements, such as smaller instruments and AI integration, promise to improve outcomes, making robotic surgery more effective in treating orbital conditions. Full article

While locally advanced rectal cancer is the first clinical suspicion for severe rectal stenosis, in extremely unusual cases a lower bowel obstruction may be related to bladder metastasis. We present the case of a 64-year-old male who was admitted for occlusive rectal tumor (4 cm from the anal verge), for which an emergency loop-colostomy was performed. After two inconclusive endoscopic biopsies, a transanal rectal tru-cut biopsy allowed for the detection of high-grade urothelial carcinoma with signet ring cells. Furthermore, primary origin was detected in a small bladder tumor. In imaging reassessment after neoadjuvant chemotherapy, regression of the lesions both from the bladder and rectum was observed. Radical surgery with total pelvic exenteration was considered in the absence of other secondary tumors, but the patient declined and continued with radiotherapy. Subsequently he developed malignant chylous ascites and unfortunately died three months later. Reviewing the literature, we found twenty-five cases of urothelial metastasis to the rectum, originating from the bladder, including this newly present case. Rectal metastasis of urothelial origin poses a two-fold challenge in terms of both diagnosis and treatment. Determining the specific features of this uncommon manifestation of a common disease will improve future approaches. Full article

Objective: We aimed to analyze the current literature for IORT in gynecological cancers and summarized clinical outcomes regarding patient selection. Methods: A systematic search was conducted utilizing PUBMED, Embase, and CINAHL to identify studies following PRISMA-ScR guidelines. A PICOS structure was utilized: population: patients with epithelial gynecological cancers; intervention: IORT; C: a comparator was not required, as we aimed to analyze patient selection; outcome: clinical outcomes and overall survival; and S: experimental and quasi-experimental analytical observational studies and descriptive observational studies, excluding case series published in English and limited to the last 10 years. Data extraction was conducted for patient selection, IORT, oncological outcomes, and morbidity. Results: A total of 707 results were identified, and 509 studies were uploaded to Covidence for screening after removing duplications. Of the 21 eligible studies, 9 were included in the final review. The total number of patients included was 348. The studies were retrospective single-institution studies, except for one. There was significant heterogeneity in their design and protocols. IORT was exclusively used for recurrent and advanced stage gynecological cancers adjunct to pelvic exenteration or laterally extended endopelvic resections with variable indications across institutions. The mean number of IORT patients per study was 2.8 per year. Survival rates were variable and dependent on the surgical margin. Endometrial cancer had a favorable outcome compared to vulvar and cervical cancers. Conclusions: Current clinical practice, as demonstrated by the research, is consistent with NCCN guidelines that endorse the application of IORT in instances of recurrent cervical, vaginal, and vulvar malignancies; however, there are no established recommendations for primary tumors. The analysis shows that there are gaps in our knowledge, mainly regarding the status of the margins, the criteria used to choose patients, and the outcomes that are specific to each histology. The standardization of protocols and prospectively powered studies are needed to refine patient selection criteria. Full article

Background: A strong body of evidence exists demonstrating deleterious relationships between abnormal body composition (BC) and outcomes in non-complex colorectal cancer. Complex rectal cancer (RC) includes locally advanced and locally recurrent tumours. This scoping review aims to summarise the current evidence examining BC in complex RC. Methods: A literature search was performed on Ovid MEDLINE, EMBASE, and Cochrane databases. Original studies examining BC in adult patients with complex RC were included. Two authors undertook screening and full-text reviews. Results: Thirty-five studies were included. Muscle quantity was the most commonly studied BC metric, with sarcopenia appearing to predict mortality, recurrence, neoadjuvant therapy outcomes, and postoperative complications. In particular, 10 studies examined relationships between BC and neoadjuvant therapy response, with six showing a significant association with sarcopenia. Only one study examined interventions for improving BC in patients with complex RC, and only one study specifically examined patients undergoing pelvic exenteration. Marked variation was also observed in terms of how BC was quantified, both in terms of anatomical location and how cut-off values were defined. Conclusions: Sarcopenia appears to predict mortality and recurrence in complex RC. An opportunity exists for a meta-analysis examining poorer BC and neoadjuvant therapy outcomes. There is a paucity of studies examining interventions for poor BC. Further research examining BC specifically in patients undergoing pelvic exenteration surgery is also lacking. Pitfalls identified include variances in how BC is measured on computed tomography and whether external cut-off values for muscle and adipose tissue are appropriate for a particular study population.

Background: Osseointegrated implants outside of dental restoration remain an integral area of facial reconstruction in which more outcomes data is needed. We aimed to describe our 13-year experience using osseointegrated implants for orbital, nasal, and auricular reconstruction, looking at general outcomes, including radiated and surgically manipulated bone. Methods: This retrospective chart review covered demographics and outcomes from January 2008 to August 2021 in patients who underwent an orbital exenteration, partial or total rhinectomy, and partial or total auriculectomy with subsequent osseointegrated implant placement. We hypothesized radiation would increase the failure rate of implants and prostheses. Results: There were 79 implants placed in 27 patients, with over half of the patients requiring implants for reconstruction because of malignancy. The success rate was 86%. Complications were uncommon. Only 2 (7.4%) patients were unable to use their prosthesis. Prior radiation and surgery to the bone were associated with an increased risk of loss of implant (p = 0.008 and p = 0.007, respectively) but not associated with other complications or prosthesis non-viability. Conclusions: Osseointegrated implants are a reliable, permanent option for a realistic prosthesis. Radiation and prior surgery are significantly associated with an increased risk of implant failure but not associated with the inability to use the prosthesis. Regardless of prior treatments, bone-retained implants should be considered in facial reconstruction, especially after failing autologous repair or with concerns for cosmetic outcomes. Full article

Introduction: Pelvic cancers present significant health challenges and often require aggressive treatment strategies. Pelvic exenteration, which involves the resection of multiple pelvic organs, is currently the only curative option for advanced or recurrent pelvic malignancies. Due to its extensive nature, it carries a high risk for postoperative complications and extended hospital stays. Current evidence suggest that improved preoperative fitness is associated with better postoperative outcomes. This study explored the relationship between preoperative self-reported physical activity levels and surgical outcomes following pelvic exenteration. Methods: This retrospective cohort study included consecutive adult patients undergoing pelvic exenteration at Royal Prince Alfred Hospital between May 2017 and December 2023. Eligible participants completed the International Physical Activity Questionnaire—Short Form (IPAQ-SF) preoperatively. Primary outcomes included postoperative morbidity, length of hospital stay, and survival. Univariate and multivariate logistic regression analyses explored the association between preoperative physical activity and postoperative outcomes. Results: A total of 256 participants were included, of which 115 (44.9%) were classified as active. Active patients experienced fewer postoperative complications (p = 0.047) and shorter hospital stays (p = 0.007), compared to inactive participants. There was no significant association between preoperative physical activity levels and survival outcomes (p = 0.749). Younger age, preoperative physical activity level, and advanced primary malignancy were significantly associated with fewer complications and shorter hospital stays. Conclusions: Higher levels of preoperative physical activity is associated with fewer postoperative complications and shorter hospital stays in patients undergoing pelvic exenteration. These findings support the potential benefits of incorporating prehabilitation programs to improve surgical outcomes and reduce healthcare costs. Full article

(1) Background: Orbital rhabdomyosarcoma is a rare and aggressive soft tissue tumor that primarily occurs in the eye socket (orbit) of children. Treatment usually involves a combination of surgery, chemotherapy, and radiation therapy, aiming to remove the tumor and prevent metastasis. (2) Methods: An institutional retrospective study was conducted with data from 39 patients with primary orbital RMS treated between 1995 and 2016 at the Amsterdam University Medical Centers/Emma Children Hospital. (3) Results: The median age at presentation was 7 years (range, 9 months to 16 years). The median follow-up period was 9.4 years (range, 3 to 25 years). Ten underwent chemotherapy and excision without additional radiotherapy. A total of 29 patients received additional local treatment: Ablative surgery MOld technique with after loading brachytherapy and surgical REconstruction (AMORE) (N = 21), proton (N = 4) or external beam radiation treatment (EBRT; N = 4). We found 14 cases with recurrences, 9 of which underwent exenteration and two of which died. The 10-year overall survival rate was 95% and the EFS was 63%. (4) Conclusions: long-term follow-up with 10-year survival rate of orbital RMS in this series was 95% achieved by local tumor control and eye preservation in 77% of our study population.

Background: Achieving evidence-based practice change in surgery has always been challenging, with many aspects of common clinical practice evolving through lower-level studies that are susceptible to bias and confounding rather than high-quality evidence. This challenge is even more pronounced in the setting of low-volume, high-complexity surgical oncology. Additionally, when the costs of interventions or technologies are high, designing and developing such studies within financially constrained national healthcare systems becomes even more complicated, potentially widening perceived healthcare inequalities between private and publicly funded systems. However, this is precisely the area where a lack of evidence can either hinder the development of significant new clinical advances or lead to the adoption of expensive and ineffective treatments. Here, we describe the novel approaches adopted in the design, development, and implementation of the ELECTRA trial, a randomised, controlled, double-blinded feasibility study with a planned extension to a late-phase trial. Methods: The Cancer Research UK ELECTRA (NCT05877352) trial is a three-armed randomised, controlled clinical trial designed to evaluate the incremental benefit of adding intraoperative electron beam radiotherapy (IOERT) to pelvic exenteration surgery for locally advanced and locally recurrent rectal cancer. ELECTRA is double-blinded, with patients, surgeons, and oncologists unaware of whether IOERT is administered or not. The primary feasibility outcome focuses on the ability to successfully recruit and randomise participants, while the subsequent primary outcome assesses IOERT field local control. Results: We describe the collaborative process involved in developing the trial, including national and international consultations to determine the best study design and the most optimal outcome measures to evaluate. We outline the extensive patient participation and input into the study design. Given the complexity and evolving nature of the field, with no clear international standardisations, we outline the processes used to address internationally agreed definitions, radiological standardisation, surgical learning curves, quality assurance, and pathological standardisation, as well as the broader impact and benefits of these activities. Finally, we describe the novel design utilised to facilitate the involvement of national and international units with varying levels of equipoise regarding IOERT. Conclusions: Historically, randomised clinical trials have not been the standard approach for evaluating surgical interventions due to their practical and methodological challenges, particularly in high-complexity, low-volume settings. Despite these difficulties, they remain the gold standard for evidence-based practice. The ELECTRA trial exemplifies a complex, innovative trial design that addresses an unmet need in a specialised area of high-complexity surgery. Using ELECTRA as an example, we highlight the genuine challenges in designing such complex trials and provide recommendations to facilitate the conduct of future well-designed surgical studies.

Background/Objectives: The management of periocular skin malignancies presents a unique challenge. Proton beam therapy, due to its sharp dose fall-off, allows for the delivery of a tumoricidal dose to the tumor while sparing adjacent normal tissues. Methods: Thirteen patients with a median age of 76.5 years received protons at our institution to a median dose of 66.6 Gy (RBE). Sixty-four percent of the lesions were basal cell carcinoma, and 22% were squamous cell carcinoma. Eighty-six percent of patients underwent biopsy only or partial resection. Fifty-seven percent of the lesions were located in the medial or lateral canthus. There was orbital invasion in 93% of the cases. Locoregional control probability and overall survival were estimated with the Kaplan–Meier method. Treatment toxicity was scored using the CTCAE 4.0. Results: At a median follow-up of 96 months, there was no local recurrence. The rate of orbital preservation was 100%. Functional vision was maintained in all the patients. There was no acute or late grade 3 or higher toxicity. Conclusions: Protons allow for long-term tumor control with eye preservation in patients with locally advanced periocular skin cancers. Larger prospective multi-institutional trials with standardized ophthalmological assessments are needed to confirm our findings. Full article

Background: Vulvar carcinoma is an uncommon gynecological tumor primarily affecting older women. Its treatment significantly impacts the quality of life and, not least, aesthetics because of the mutilating surgery it requires. Objectives: The management requires a multidisciplinary team of specialists who know how to care for the patient in her entirety, not neglecting psychological aspects and reconstructive surgery. How do the guidelines address multidisciplinarity, team surgical management, passing through preoperative diagnosis, and follow-up in such a challenging rare tumor to treat? Methods: To answer these questions, we compared the main scientific recommendations to identify similarities and differences in diagnostic and therapeutic management to provide an overview of the gaps that there are currently in European and American international recommendations in providing management guidance in a cancer that is both among the rarest and most difficult to manage. In this way, we aim to encourage an update in practices based on the latest scientific evidence. Results: A review of various international guidelines, some dating back to 2014, shows significant variation in approaches, ranging from initial diagnostic procedures to managing relapses. The most recent guidelines also lacked references to the latest literature, indicating that more robust scientific evidence is needed before new treatments, such as electrochemotherapy for palliation and reconstructive surgery post exenteration, can be widely adopted. Conclusions: From the systematic comparison of the main international guidelines, a strong heterogeneity emerged in the diagnostic and therapeutic recommendations as well as for the multidisciplinary approach that today is essential. Our work certainly stimulated an update of the main guidelines. Full article

Background: Conventional pelvic exenteration (PE) comprises the removal of all or most central pelvic organs and is established in clinical practise. Previously, tumours involving bone or lateral sidewall structures were deemed inoperable due to associated morbidity, mortality, and poor oncological outcomes. Recently however high-complexity PE is increasingly described and is defined as encompassing conventional PE with the additional resection of bone or pelvic sidewall structures. This observational cohort study aimed to assess surgical outcomes, health-related quality of life (HrQoL), decision regret, and costs of high-complexity PE for more advanced tumours not treatable with conventional PE. Methods: High-complexity PE data were retrieved from a prospectively maintained quaternary database. The primary outcome was overall survival. Secondary outcomes were perioperative mortality, disease control, major morbidity, HrQoL, and health resource use. For cost–utility analysis, a no-PE group was extrapolated from the literature. Results: In total, 319 cases were included, with 64 conventional and 255 high-complexity PE, and the overall survival was equivalent, with medians of 10.5 and 9.8 years (p = 0.52), respectively. Local control (p = 0.30); 90-day mortality (0.0% vs. 1.2%, p = 1.00); R0-resection rate (87% vs. 83%, p = 0.08); 12-month HrQoL (p = 0.51); and decision regret (p = 0.90) were comparable. High-complexity PE significantly increased overall major morbidity (16% vs. 31%, p = 0.02); and perioperative costs (GBP 37,271 vs. GBP 45,733, p < 0.001). When modelled against no surgery, both groups appeared cost-effective with incremental cost-effectiveness ratios of GBP 2446 and GBP 5061. Conclusions: High-complexity PE is safe and feasible, offering comparable survival outcomes and HrQoL to conventional PE, but with greater morbidity and resource use. Despite this, it appears cost-effective when compared to no surgery and palliation. Full article

Locally recurrent rectal cancer (LRRC), which occurs in 6–12% of patients previously treated with surgery, with or without pre-operative chemoradiation therapy, represents a complex and heterogeneous disease profoundly affecting the patient’s quality of life (QoL) and long-term survival. Its management usually requires a multidisciplinary approach, to evaluate the several aspects of a LRRC, such as resectability or the best approach to reduce symptoms. Surgical treatment is more complex and usually needs high-volume centers to obtain a higher rate of radical (R0) resections and to reduce the rate of postoperative complications. Multiple factors related to the patient, to the primary tumor, and to the surgery for the primary tumor contribute to the development of local recurrence. Accurate pre-treatment staging of the recurrence is essential, and several classification systems are currently used for this purpose. Achieving an R0 resection through radical surgery remains the most critical factor for a favorable oncologic outcome, although both chemotherapy and radiotherapy play a significant role in facilitating this goal. If a R0 resection of a LRRC is not feasible, palliative treatment is mandatory to reduce the LRRC-related symptoms, especially pain, minimizing the effect of the recurrence on the QoL of the patients. The aim of this manuscript is to provide a comprehensive narrative review of the literature regarding the management of LRRC. Full article

Background/Objectives: Epiphora, or excessive tearing, is a common symptom often attributed to benign conditions such as dry eye or nasolacrimal duct obstruction. However, it can also be an early indicator of lacrimal sac tumors, which are frequently misdiagnosed or diagnosed late due to their subtle presentation. This study aims to identify the clinical features that contribute to delays and misdiagnoses of lacrimal sac tumors in patients presenting with epiphora, with the goal of improving early detection and treatment outcomes. Methods: This retrospective study reviewed medical records from Taipei Veterans General Hospital between 2007 and 2023, focusing on patients who presented with epiphora and were later diagnosed with pathologically confirmed lacrimal sac tumors. Inclusion criteria were limited to cases that were initially misdiagnosed or had a delayed diagnosis, with imaging and clinical evaluations confirming tumor-related tear drainage obstruction. Patients with non-tumor causes of epiphora were excluded. Results: Eleven cases of lacrimal sac tumors were identified, including two benign and nine malignant tumors. The average duration from symptom onset to diagnosis was 22.4 months. Common symptoms included epiphora (100%), discharge (54.5%), and hemolacria (18.2%). Subtle clinical signs, such as asymmetry in the medial canthal region and non-tender swelling, were frequently noted. Despite receiving appropriate surgical and adjuvant treatments, the impact of delayed diagnosis was significant. Two patients succumbed to tumor-related disease; one developed lung metastasis 12 years after diagnosis, and another experienced recurrence during a six-year follow-up after undergoing extensive exenteration, adjuvant chemotherapy, and radiotherapy. Conclusions: Lacrimal sac tumors can present insidiously with symptoms often mistaken for benign conditions, leading to significant diagnostic delays. Thorough history taking, meticulous physical examination, and timely imaging are crucial for early detection. Increased clinician awareness and a high index of suspicion for lacrimal sac tumors in patients with atypical epiphora are essential to improve prognosis and reduce the risk of severe outcomes.
