Sexual, bladder and bowel function following different minimally invasive techniques of radical hysterectomy in patients with early-stage cervical ca…
2021
Abstract Purpose Despite the establishment of radical surgery for therapy of cervical cancer, data on quality of life and patient-reported outcomes are scarce. The aim of this retrospective cohort study was to evaluate bladder, bowel and sexual function in women who underwent minimally invasive surgery for early-stage cervical cancer. Methods From 2007–2013, 261 women underwent laparoscopically assisted radical vaginal hysterectomy (LARVH = 45), vaginally assisted laparoscopic or robotic radical hysterectomy (VALRRH = 61) or laparoscopic total mesometrial resection (TMMR = 25) and 131 of them completed the validated German version of the Australian Pelvic Floor Questionnaire (PFQ).

Tracheal development and the von Hippel-Lindau tumor suppressor homolog in Drosophila.
2000
von Hippel-Lindau disease is a hereditary cancer syndrome. Mutations in the VHL tumor suppressor gene predispose individuals to highly vascularized tumors. However, VHL-deficient mice die in utero due to a lack of vascularization in the placenta. To resolve the contradiction, we cloned the Drosophila VHL homologue (d-VHL) and studied its function. It showed an overall 50% similarity to the human counterpart and 76% similarity in the crucial functional domain: the elongin C binding site. The putative d-VHL protein can bind Drosophila elongin C in vitro. During embryogenesis, d-VHL is expressed in the developing tracheal regions where tube outgrowth no longer occurs. Reduced d-VHL activity (u…
Immune escape of AKT overexpressing ovarian cancer cells
2012
Platinum-resistance is the most crucial problem for treatment of ovarian cancer. There is a clinical need for new treatment strategies which overcome platinum resistance. As survival is strongly influenced by immunological parameters, immunotherapeutic strategies appear promising. Therefore a better understanding of the interaction between ovarian tumour cells and cells of the immune system is a necessary prerequisite. In the present study we aimed to enlighten the interactions between platinum resistant and platinum sensitive ovarian cancer cells and natural-killer (NK)-cells. Modified FATAL assay was used for determining the killing efficiency of NK-cells for the parental A2780 cells and …
Indocyanine Green to Assess Vascularity of Ileal Conduit Anastomosis During Pelvic Exenteration for Recurrent/Persistent Gynecological Cancer: A Pilo…
2021
IntroductionPelvic exenteration performed for recurrent/persistent gynecological malignancies has been associated with urological short- and long-term morbidity due to altered vascularization of tissues for previous radiotherapy. The aims of the present study were to describe the use of intravenous indocyanine green (ICG) to assess vascularity of urinary diversion (UD) after pelvic exenteration for gynecologic cancers, to evaluate the feasibility and safety of this technique, and to assess the postoperative complications.MethodsProspective, observational, single-center, pilot study including consecutive patients undergoing anterior or total pelvic exenteration due to persistent/recurrent gy…
A survey of seroprevalence of human papillomavirus types 16, 18 and 33 among children.
1999
The importance and natural history of HPV infections in childhood is incompletely understood. We performed a survey for presence of serum antibodies to HPV capsids among 1031 children aged 0 to 13 years, resident in Stockholm, Sweden. The HPV seroprevalence among these children was 3.0% for HPV16, 0.6% for HPV18 and 2.7% for HPV33. By comparison, among simultaneously analyzed positive control panels comprising women with CIN or healthy women with type-specific cervical HPV DNA, seroprevalence of HPV 16, 18 and 33 was 69%, 58% and 63% respectively. The results suggest that HPV infection in childhood is not common.

The full publication in Lancet Oncology of the Stockholm III trial helps us to understand that short-course radiotherapy in patients with localised rectal cancer could also be followed by delayed surgery.1 During more than 14 years, more than 800 patients with rectal cancer not showing unresectable features were randomised in a two-arm versus three-arm study with a non-inferiority design. Patients could be randomised to short-course radiotherapy (5×5 Gy) and immediate (within a week) versus delayed (4–8 weeks) surgery. In the three-arm randomisation patients could also be allocated to a long course of concurrent chemoradiation (25×2 Gy), with surgery performed 6–8 weeks thereafter. Time to …
Brain metastases following interleukin-2 plus interferon-alpha-2a therapy
2003
Abstract This study analyses the frequency and therapy of brain metastases in 94 stage IV melanoma patients after treatment with high-dose interleukin-2 (IL-2) and interferon-α (IFN-α) within three subsequent trials between 1990 and 1995. Central nervous system (CNS) metastases occurred in 28 patients (30%) during the potential follow-up period of 6 years. Time to occurence of brain metastases varied between 1 and 53 months, with a median of 10 months. Of 28 patients, 19 had
CT and MR Imaging of Retroperitoneal Sarcomas: A Practical Guide for the Radiologist
2023
Primary retroperitoneal sarcomas (RPS) represent around 10–16% of all sarcomas, with liposarcomas and leiomyosarcomas being the most common subtypes. RPS have some peculiar characteristics, imaging appearances, worse prognosis, and complications compared to other locations of sarcoma. Commonly, RPS primarily present as large masses, progressively encasing adjacent structures, causing mass effect, and complications. RPS diagnosis is often challenging, and these tumors may be overlooked; however, failure to recognize RPS characteristics leads to a worse prognosis for the patients. Surgery is the only recognized curative treatment, but the anatomical constraints of the retroperitoneum limit th…
Segmental Ureterectomy Versus Radical Nephroureterectomy in Older Patients Treated for Upper Tract Urothelial Carcinoma
2022
Introduction: The world population is ageing and surgical procedures for older patients are associated with higher perioperative morbidity and mortality rates than in younger patients. Segmental ureterectomy (SU) has been proposed as an alternative to radical nephroureterectomy (RNU) for selected upper tract urothelial carcinomas (UTUC), to reduce post-operative morbidity, and preserve renal function. The aim of this study was to compare RNU and SU in terms of post-operative complications, functional outcomes, and overall survival (OS) in older patients treated for UTUC. Materials and methods: Data of patients aged 75 years or older and treated for UTUC were included. The primary outcome wa…
Continuous cardiac index trending (ProAQT) via a radial arterial line versus standard care in general surgical patients
2015
Introduction Several single-center studies and meta-analyses have shown that perioperative goal-directed therapy may significantly improve outcomes in general surgical patients. We hypothesized that using a treatment algorithm based on pulse pressure variation, cardiac index trending by radial artery pulse contour analysis, and mean arterial pressure in a study group, would result in reduced complications, reduced length of hospital stay and quicker return of bowel movement postoperatively in abdominal surgical patients, when compared to a control group. Methods 160 patients undergoing elective major abdominal surgery were randomized to the Study Group (79 patients) or to the Control Group …
