    reast cancer (BrC) is the most common non-dermatologic cancer in women. It frequently metastasizes to lung, liver and bone, while the urinary bladder is considered as an unusual site for BrC metastases. Materials and methods: Four years after her first oncologic surgical approach, a known BrC patient complained of a left flank pain, dysuria and urgency. Computed tomography (CT scan) imaging showed an irregular thickening of the left bladder wall and bilateral hydronephrosis. Results: A bladder metastases from BrC was diagnosed based on a histological examination of a transurethral resection of the bladder (TURB-T) specimen. Conclusions: In patients with a history of BrC, urinary bladder screening is not needful. However, if low urinary symptoms persist, an evaluation of the bladder should be considered to rule out metastatic involvement

    With "contact surface area" (CSA) we refers to the area of contact between a tumor and an organ. This indicator has been identified as a predictive factor for surgical peri-operative parameters, particularly in the context of kidney cancer. However, state-of-the-art algorithms for computing the CSA rely on assumptions about the tumor shape and require manual human annotation. In this study, we introduce an innovative method that relies on 3D reconstructions of tumors and organs to provide an accurate and objective estimate of the CSA. Our approach consists of a segmentation protocol for reconstructing organs and tumors from Computed Tomography (CT) images and an algorithm leveraging the reconstructed meshes to compute the CSA. With the aim to contributing to the literature with replicable results, we provide an open-source implementation of our algorithm, along with an easy-to-use graphical user interface to support its adoption and widespread use. We evaluated the accuracy of our method using both a synthetic dataset and reconstructions of 87 real tumor-organ pairs

    To the Editor, Good surgical training is essential for the formation of excellent surgeons, consequently providing the best possible care for our patients in the future. Considering the increase in surgeon shortage over the last two decades (estimated between 14,300 and 23,400 by the year 2032 only in the US), it is important for filling the national health system's needs as well [...]

    Kaposi's sarcoma: An unusual penile lesion in a HIV negative patient

    Kaposi's sarcoma (KS) of the penis is a very rare lesion and it is usually observed in HIV-infected patients. We introduce a case of KS of the penis in a 75 years old HIV negative patient with a peripheral T-cell lymphoma. He came to our attention with a painful ulcerated red lesion on the glans that stretched from the urethral meatus to the coronal skin. This lesion was found to be a KS balanopreputial in the classical variant. Penile KS must be included in the differential diagnosis of genital diseases especially when the clinical features of the lesion are aspecific and diagnosis can be made histologically by performing a biopsy

    Radical Prostatectomy and Intraoperative Radiation Therapy in High-Risk Prostate Cancer

    Intraoperative electron beam radiotherapy (IOERT) for prostate cancer (PC) is a radiotherapeutic technique, giving high doses of radiation during radical prostatectomy (RP). This paper presents the published treatment approaches for intraoperative radiotherapy analyzing functional outcome, morbidity, and oncological outcome in patients with clinical intermediate-high-risk prostate cancer. A systematic review of the literature was performed, searching PubMed and Web of Science. A “free text” protocol using the term intraoperative radiotherapy and prostate cancer was applied. Ten records were retrieved and analyzed including more than 150 prostate cancer patients treated with IOERT. IOERT represents a feasible technique with acceptable surgical time and minimal toxicity. A greater number of cases and longer follow-up time are needed in order to assess the long-term side effects and oncological outcome

    Intraoperative radiotherapy in gynaecological and genito-urinary malignancies: Focus on endometrial, cervical, renal, bladder and prostate cancers

    Get PDF
    Intraoperative radiotherapy (IORT) refers to the delivery of a single radiation dose to a limited volume of tissue during a surgical procedure. A literature review was performed to analyze the role of IORT in gynaecological and genito-urinary cancer including endometrial, cervical, renal, bladder and prostate cancers. Literature search was performed by Pubmed and Scopus, using the words "intraoperative radiotherapy/IORT", "gynaecological cancer", "uterine/endometrial cancer", "cervical/cervix cancer", "renal/kidney cancer", "bladder cancer" and "prostate cancer". Forty-seven articles were selected from the search databases, analyzed and briefly described. Literature data show that IORT has been used to optimize local control rate in genito-urinary tumours mainly in retrospective studies. The results suggest that IORT could be advantageous in the setting of locally advanced and recurrent disease although further prospective trials are needed to confirm this findings

    Extraperitoneal cystectomy with ureterocutaneostomy derivation in fragile patients - should it be performed more often?

    Introduction and objectives: Radical cystectomy (RC) continues to be standard of care for muscle-invasive bladder cancer and recurrent or refractory nonmuscle invasive bladder cancer. Unfortunately, it has high rates of perioperative morbidity and mortality. One of the most important predictors of postoperative outcomes is frailty, while the majority of complications are diversion related. The aim of our study was to evaluate safety of extraperitoneal cystectomy with ureterocutaneostomy in patients considered as frail. Materials and methods: We retrospectively collected data of frail patients who underwent extraperitoneal cystectomy with ureterocutaneostomy from October 2018 to August 2020 in a single center. We evaluated frailty by assessing patients' age, body mass index (BMI), nutritional status by Malnutrition Universal Screening Tool, overall health by RAI (Risk Analysis Index) and ASA (American Society of Anaesthesiologists) score, and laboratory analyses. We observed intraoperative outcomes and rates of perioperative (within 30 days) and early postoperative (within 90 days) complications (Clavien-Dindo classification). We defined extraperitoneal cystectomy with ureterocutaneostomy as safe if patients did not develop Clavien Dindo IIIb, or worse, complication. Results: A total of 34 patients, 3 female and 31 male, were analyzed. The median age was 77, BMI 26, RAI 28, ASA 3 and the majority had preexisting renal insufficiency. Blood analyses revealed presence of severe preoperative hypoalbuminemia and anemia in half of our cohort. Intraoperative median blood loss was 250 cc, whilst operative time 245 min. During perioperative period 60% of our cohort developed Clavien Dindo II complication and during early postoperative period 32% of patients required readmission. One death occurred during early postoperative period (2.9%). After 12 months of follow-up, we observed stability of the renal function for most patients. Conclusions: We believe that extraperitoneal cystectomy with ureterocutaneostomy could be considered as a treatment option for elderly and/or frail patients

    The Effect of Anatomical Location of Lymph Node Metastases on Cancer Specific Survival in Patients with Clear Cell Renal Cell Carcinoma

    Background: Positive nodal status (pN1) is an independent predictor of survival in renal cell carcinoma (RCC) patients. However, no study to date has tested whether the location of lymph node (LN) metastases does affect oncologic outcomes in a population submitted to radical nephrectomy (RN) and extended lymph node dissection (eLND). Objective: To describe nodal disease dissemination in clear cell RCC (ccRCC) patients and to assess the effect of the anatomical sites and the number of nodal areas affected on cancer specific mortality (CSM). Design, setting and partecipants: The study included 415 patients who underwent RN and eLND, defined as the removal of hilar, side-specific (pre/paraaortic or pre/paracaval) and interaortocaval LNs for ccRCC, at two institutions. Outcome measurement and statistical analysis: Descriptive statistics were used to depict nodal dissemination in pN1 patients, stratified according to nodal site and number of involved areas. Multivariable Cox regression analyses and Kaplan-Meier curves were used to explore the relationship between pN1 disease features and survival outcomes. Results and limitations: Median number of removed LN was 14 (IQR 9\u201319); 23% of patients were pN1. Among patients with one involved nodal site, 54 and 26% of patients were positive only in side-specific and interaortocaval station, respectively. The most frequent nodal site was the interaortocaval and side-specific one, for right and left ccRCC, respectively. Interaortocaval nodal positivity (HR 2.3, CI 95%: 1.3\u20133.9, p < 0.01) represented an independent predictor of CSM. Conclusions: When ccRCC patient harbour nodal disease, its spreading can occur at any nodal station without involving the others. The presence of interoartocaval positive nodes does affect oncologic outcomes. Patient summary: Lymph node invasion in patients with clear cell renal cell carcinoma is not following a fixed anatomical pattern. An extended lymph node dissection, during treatment for primary kidney tumour, would aid patient risk stratification and multimodality upfront treatment
