Abstract
Abstract
INTRODUCTION
Colombia has a population of roughly 49 million people of predominantly Mestizo ethnicity. Cancer has become a growing public health problem in Colombia with nearly 71,000 newly diagnosed malignant tumors per year. It is expected that by 2035, 150,000 new cases of cancer will be diagnosed, making Colombia an intermediate country with regards to global cancer incidence according to IARC.
METHODS
Epidemiological data on breast cancer is scarce and varied due to multiple sources of information. These numbers are obtained thru population-based cancer registries that represent 4 distinct regions of the country. Other data originate from non-governmental institutions and healthcare providers within Colombia. The Colombian National Cancer Institute publishes a Cancer Mortality Atlas annually.
RESULTS
Local cancer registries have shown increases in breast cancer incidence in Colombia. In 2007, age-standardized incidence rate was 27.8 per 100,000 persons increasing to 49.7 cases per 100,000 persons in 2012. Approximately, 2200 women die every year in Colombia due to breast cancer with rates increasing historically, but now are stabilizing. Advanced breast cancers are most frequently found among women without health insurance, while early breast cancers are usually found among working women and those covered by private health insurance. Early breast cancer screening was made mandatory as public policy in the year 2000. However, only 30% of health care coverage was reported, translating to very low coverage by opportunistic screening programs with only 33% of women having had a mammography. In 2012, a National Cancer Control Plan was planned and implemented. It aims to increase early stage cancer diagnosis, increase biannual screening coverage, and guarantee timely access to diagnosis and treatment. A national health survey in 2015 showed only 48% of women had an annual mammographic screening. Multiple disparities have been found with regards to screening and early diagnosis such as economic strata, health insurance coverage, origin, and accessibility. Specifically, data shows that 23% needed to travel in order to obtain access to mammography. Often it is necessary for some patients to sue healthcare insurance systems to obtain specific health care, causing an increase in time to diagnosis and treatment. In 2016, on average a 90-day period was reported from time of onset of symptoms to suspected diagnosis of breast cancer, while the time to the initiation of treatment was 100 days for chemotherapy and close to 120 days for surgery.
DISCUSSION
These data serve to impact the landscape of breast cancer and improve patient outcomes in Colombia. While the National Cancer Plan has led to major changes, a big challenge remains related to the delays between suspicion of breast cancer and diagnosis and treatment. Quality of care provided by private and public insurance administrators is also of concern. General practitioners should receive more detailed training in breast cancer detection and management. The healthcare system should provide quality cancer care with urgent improvement in mammography, especially in more rural areas. Widely, more timely and appropriate follow-up is needed.

Abstract
Canonical Wnt signaling is crucial for vascularization of the central nervous system and blood-brain barrier (BBB) formation. BBB formation and modulation are not only important for development, but also relevant for vascular and neurodegenerative diseases. However, there is little understanding of how Wnt signaling contributes to brain angiogenesis and BBB formation. Here we show, using high resolution in vivo imaging and temporal and spatial manipulation of Wnt signaling, different requirements for Wnt signaling during brain angiogenesis and BBB formation. In the absence of Wnt signaling, premature Sphingosine-1-phosphate receptor (S1pr) signaling reduces VE-cadherin and Esama at cell-cell junctions. We suggest that Wnt signaling suppresses S1pr signaling during angiogenesis to enable the dynamic junction formation during anastomosis, whereas later S1pr signaling regulates BBB maturation and VE-cadherin stabilization. Our data provides a link between brain angiogenesis and BBB formation and identifies Wnt signaling as coordinator of the timing and as regulator of anastomosis.

Abstract
Angiogenesis is a dynamic process relying on endothelial cell rearrangements within vascular tubes, yet the underlying mechanisms and functional relevance are poorly understood. Here we show that PI3Kα regulates endothelial cell rearrangements using a combination of a PI3Kα-selective inhibitor and endothelial-specific genetic deletion to abrogate PI3Kα activity during vessel development. Quantitative phosphoproteomics together with detailed cell biology analyses in vivo and in vitro reveal that PI3K signalling prevents NUAK1-dependent phosphorylation of the myosin phosphatase targeting-1 (MYPT1) protein, thereby allowing myosin light chain phosphatase (MLCP) activity and ultimately downregulating actomyosin contractility. Decreased PI3K activity enhances actomyosin contractility and impairs junctional remodelling and stabilization. This leads to overstretched endothelial cells that fail to anastomose properly and form aberrant superimposed layers within the vasculature. Our findings define the PI3K/NUAK1/MYPT1/MLCP axis as a critical pathway to regulate actomyosin contractility in endothelial cells, supporting vascular patterning and expansion through the control of cell rearrangement. Angiogenesis requires dynamic endothelial rearrangements and relative position changes within the vascular tubes. Here the authors show that a PI3K/NUAK1/MYPT1/MLCP pathway regulates actomyosin contractility in endothelial cells and cellular rearrangement during vascular patterning.

Abstract
Angiogenesis and vascular remodeling are driven by extensive endothelial cell movements. Here, we present in vivo evidence that endothelial cell movements are associated with oscillating lamellipodia-like structures, which emerge from cell junctions in the direction of cell movements. High-resolution time-lapse imaging of these junction-based lamellipodia (JBL) shows dynamic and distinct deployment of junctional proteins, such as F-actin, VE-cadherin and ZO1, during JBL oscillations. Upon initiation, F-actin and VE-cadherin are broadly distributed within JBL, whereas ZO1 remains at cell junctions. Subsequently, a new junction is formed at the front of the JBL, which then merges with the proximal junction. Rac1 inhibition interferes with JBL oscillations and disrupts cell elongation-similar to a truncation in ve-cadherin preventing VE-cad/F-actin interaction. Taken together, our observations suggest an oscillating ratchet-like mechanism, which is used by endothelial cells to move over each other and thus provides the physical means for cell rearrangements.

Abstract
VCP/p97 (valosin containing protein) is a key regulator of cellular proteostasis. It orchestrates protein turnover and quality control in vivo, processes fundamental for proper cell function. In humans, mutations in VCP lead to severe myo- and neuro-degenerative disorders such as inclusion body myopathy with Paget disease of the bone and frontotemporal dementia (IBMPFD), amyotrophic lateral sclerosis (ALS) or and hereditary spastic paraplegia (HSP). We analyzed here the in vivo role of Vcp and its novel interactor Washc4/Swip (WASH complex subunit 4) in the vertebrate model zebrafish (Danio rerio). We found that targeted inactivation of either Vcp or Washc4, led to progressive impairment of cardiac and skeletal muscle function, structure and cytoarchitecture without interfering with the differentiation of both organ systems. Notably, loss of Vcp resulted in compromised protein degradation via the proteasome and the macroautophagy/autophagy machinery, whereas Washc4 deficiency did not affect the function of the ubiquitin-proteasome system (UPS) but caused ER stress and interfered with autophagy function in vivo. In summary, our findings provide novel insights into the in vivo functions of Vcp and its novel interactor Washc4 and their particular and distinct roles during proteostasis in striated muscle cells.

Abstract
The transport of intense ion beams is affected by the collective behavior of this kind of multi-particle and multi-species system. The space charge expressed by the generalized perveance dominates the dynamical process of thermalisation, which leads to emittance growth. To prevent changes of intrinsic beam properties and to reduce the intensity dependent focusing forces, space charge compensation seems to be an adequate solution. In the case of positively charged ion beams, electrons produced by residual gas ionization and secondary electrons provide the space charge compensation. The influence of the compensation particles on the beam transport and the local degree of space charge compensation is given by different beam properties as well as the ion beam optics. Especially for highly charged ion beams, space charge compensation in combination with poor vacuum conditions leads to recombination processes and therefore increased beam losses. Strategies for providing a compensation-electron reservoir at very low residual gas pressures will be discussed.

Abstract
INTRODUCTION In economic theory economic surplus refers to two related quantities: Consumer and producer surplus. Applying this theory to health care "convenience" could be one way how consumer benefits might manifest itself. METHODS Various areas of economic surplus were identified and subsequently screened and analyzed in Germany, Spain, The Netherlands, and the UK: Cesarean births, emergency room visits (nights or weekends), drug availability after test results, and response surplus. A targeted literature search was being conducted to identify the associated costs. Finally the economic surplus (convenience value) was calculated. RESULTS The economic surplus for different health care areas was being calculated. The highest economic surplus was obtained for the example of response surplus IVF-treatments in The Netherlands. CONCLUSION The analyzed examples in this article support the underlying hypothesis for this research: "Value of convenience defined as the consumer surplus in health care can be shown in different health care settings." Again, this hypothesis should be accepted as a starting point in this research area and hence further primary research is strongly recommended in order to fully proof this concept.

Abstract
This study examines the invasion history of alien fish species based on exhaustive national data sets on fish invasions of two contiguous central European countries (Germany and Austria). Fifteen alien fish species are currently established in both countries, constituting 14 and 17% of the total freshwater fish fauna of Germany and Austria, respectively. In both countries, six alien species are present, but not established. The status of five alien species in Germany and three species in Austria remains unknown. Accumulation rates of alien fish species have increased in recent decades with >50% of them reported after 1971. North America and Asia were the primary sources of alien fish species in Germany and Austria up to the 1980s, whereas European species of Ponto-Caspian origin dominate now. Fisheries (including aquaculture) and the animal trade were responsible for most earlier introductions, whereas waterways were the main pathway for recent invaders. The extent of the spatial distribution of alien species was positively correlated with residence time, i.e. the time elapsed since the first national record. Different thermal preferences of early invaders (mostly coldwater species) and new invaders (typically warmwater adapted) may benefit the latter in the face of climate change. It is concluded that new challenges for alien fish management arise and that ecosystem-based approaches as endorsed by the E.U. Water Framework Directive (maintaining or restoring good ecological status of rivers and streams) should become the centrepiece of river management in Europe.

Abstract
Although increasing evidence suggests a critical role for platelet-derived growth factor (PDGF) receptor β (β-PDGFR) signaling in prostate cancer (PCa) progression, the precise roles of β-PDGFR and PDGF isoform-specific cell signaling have not been delineated. Recently, we identified the PDGF-D isoform as a ligand for β-PDGFR in PCa and showed that PDGF-D is activated by serine protease-mediated proteolytic removal of the CUB domain in a two-step process, yielding first a hemidimer (HD) and then a growth factor domain dimer. Herein, we demonstrate that the expression of PDGF-D in human PCa LNCaP cells leads to enhanced bone tumor growth and bone responses in immunodeficient mice. Histopathological analyses of bone tumors generated by PDGF-D-expressing LNCaP cells (LNCaP-PDGF-D) revealed osteolytic and osteoblastic responses similar to those observed in human PCa bone metastases. Importantly, we discovered a novel function of PDGF-D in the regulation of osteoclast differentiation, independent of the RANKL/RANK signaling axis. Although both PDGF-B and -D were able to activate β-PDGFR, only PDGF-D was able to induce osteoclastic differentiation in vitro, and upregulate the expression and nuclear translocation of nuclear factor of activated T cells 1, a master transcription factor for osteoclastogenesis. Taken together, these results reveal a new function of PDGF-D as a regulator of osteoclastic differentiation, an activity critical for the establishment of skeletal metastatic deposit in PCa patients.

Abstract
Metastatic renal cell carcinoma has a poor prognosis with a median overall survival rate of approximately 2 years. The current standard medicinal therapy includes the use of tyrosine kinase inhibitors or antiangiogenic substances, such as VEGF receptor antagonists. Improvement in clinical response is to be expected when surgical tumor debulking by nephrectomy or metastasectomy is performed before medicinal therapy is started and should be considered especially in patients with a good performance status. Additionally, complete resection of solitary or at least a limited number of metastases can potentially be done with curative intent. Radiotherapy remains the standard procedure for palliative therapy of brain metastases to reduce clinical symptoms and to improve intracerebral tumor control.

Abstract
e17553 Background: Although new treatment options for advanced NSCLC can offer improved survival over standard treatment with chemotherapy (CT) they should also offer value for money. Bevacizumab (BEV), a humanized monoclonal antibody (MAb) directed against vascular endothelial growth factor when combined with CT increases overall survival (median 13.6 months in the AVAiL study) and progression-free survival (PFS) in patients with advanced NSCLC when compared with CT alone. Cetuximab (CTX), an IgG1 MAb which targets the epidermal growth factor receptor achieved a median survival time of 11.3 months when combined with CT in the FLEX study and marketing authorization is anticipated in 2009. The aim of this study was to compare the costs of treating NSCLC with BCG or CVC in Germany. Methods: A Markov model was used to compare drug and administration costs associated with treating advanced or recurrent NSCLC with either BCG or CVC. The model assumes patients move from non-progressive to progressed disease prior to death, according to transition probabilities derived from an indirect comparison of the efficacy of BCG and CVC in terms of PFS using data from the respective pivotal trials and appropriate indirect comparison methodology. Cost data were derived from local sources. Drug costs assumed CT was given for up to 6 cycles, that CTX was administered at an initial dose of 400 mg/m2 followed by 250 mg/m2 weekly until progression and that BEV was administered at 7.5 mg/kg until progression. The model estimated average drug and administration costs per patient treated with either BCG or CVC. Results: The mean total cost of BCG treatment was €4713 less per patient when compared with CVC (€28342 vs. €33055). The addition of BEV to CT was less costly than the addition of CTX to CT (€18796 vs. €29502) and the administration costs were also lower (€391 vs. €1179). Conclusions: Targeted therapy using BEV is less costly than CTX in Germany and thus, from a budget perspective, offers the best value for money strategy for improving outcomes in patients with advanced NSCLC. Furthermore, costs savings with BCG in Germany are likely to be increased when gemcitabine comes off-patent in 2009. [Table: see text]

Abstract
OBJECTIVE To study clinical and histopathologic parameters after cystectomy and lymphadenectomy in non-muscle-invasive transitional cell carcinoma (TCC) of the bladder and their association with the prevalence of lymph node metastases (N+). PATIENTS AND METHODS Of 866 patients treated with radical cystectomy and lymphadenectomy, 219 had non-muscle-invasive TCC of the bladder. The prevalence of N+ was related to parameters such as gender, age, number of transurethral resections of the bladder (TURBs), intervals between first TURB and cystectomy, adjuvant therapy, maximum histopathologic tumor stage and grade at TURB, and tumor upstaging in the cystectomy specimen by univariate and multivariate analysis. RESULTS A total of 33 patients (15%) had N+. By multivariate analyses, tumor upstaging and the number of TURBs were independent predictors of N+ at cystectomy. The number of TURBs increased the prevalence of N+ from 8% (one TURB) to 24% (two to four TURBs). Tumor upstaging in the cystectomy specimen increased the prevalence of N+ from 4% to 36%. CONCLUSION Inappropriate delay and staging errors of"high risk" non-muscle-invasive TCC of the bladder contribute to an increased prevalence of N+ and should be avoided. In our series, the number of TURBs and tumor upstaging in the cystectomy specimen were independent predictors for N+ by multivariate analysis.

Abstract
Rho GTPases regulate diverse cellular functions including adhesion, cytokinesis and motility, as well as the activity of the transcription factors NF-kappaB, serum response factor and C/EBP. alpha-Catulin, an alpha-catenin-related protein that shares structural similarities with cytoskeletal linker proteins, facilitates Rho signalling by serving as a scaffold for the Rho-specific guanine nucleotide exchange factor Lbc. We report here that alpha-catulin also interacts with a key component of the NF-kappaB signalling pathway, namely the IkappaB kinase (IKK)-beta. In co-immunoprecipitations, alpha-catulin can bind IKK-beta and Lbc. Ectopic expression of alpha-catulin augmented NF-kappaB activity, promoted cell migration and increased resistance to apoptosis, whereas knockdown experiments showed the opposite effects. Together, these features suggest that alpha-catulin has tumorigenic potential.

Abstract
The ageing of our society continuously increases the number of frail elderly patients in the incontinence cohort. Shortage of financial and personnel resources demands reasonable and purposeful use of the diagnostic armamentarium. All intended diagnostic procedures should follow an algorithm hierarchized for invasiveness and should be limited to the minimum extent necessary for initiation of a conservative first-line treatment. Reasonable diagnostics objectify patients' complaints, differentiate between subgroups, reveal underlying pathologies and comorbidities, classify incontinence severity, support the therapeutic strategy, identify possible treatment complications and serve as follow-up tools. Diagnostic results have to be documented in detail and the procedures must be as easy and minimally invasive as possible. Basic diagnostics in urinary incontinence comprise patient history, clinical examination, urinalysis, uroflowmetry and sonographic post-void residual measurement, voiding diary and evaluation of the mental status. With these procedures, the vast majority of elderly patients can be classified correctly and a conservative first-line treatment can be started. Only a minority of patients with incongruent diagnostic results or recurrent incontinence refractory to conservative therapy should undergo further special diagnostics (urethrocystoscopy, urodynamics, morphologic and functional radiologic imaging, perineal or introital ultrasound) if they lead to therapeutic consequences. If not, expensive special diagnostics should be omitted in elderly patients due to their inherent morbidity.

Abstract
Nowadays, male stress urinary incontinence is rare and almost always of iatrogenic origin (radiotherapy, pelvic surgery). However, the prognosis of urinary incontinence following surgery is good and can be improved by pelvic floor muscle exercises in combination with biofeedback systems. For the remaining patient cohort with persistent urinary incontinence, several established surgical treatment options are available. Suburothelial injections of bulking agents can easily be performed in an ambulatory setting. However, regardless of the material used, long-term results are disappointing. Moreover, the residual urethral function deteriorates due to cicatrization of the suburothelial plexus with consequent loss of urethral elasticity. The fascial sling procedure in males has to be performed in preoperated areas and is as technically demanding for the surgeon as it is burdening for the patient. Alloplastic material is not used, thus minimizing risks for arrosion or infection. Since the sling tension can neither be standardized nor postoperatively readjusted, the risk of overcorrection is considerable and the success of the procedure is heavily dependent on the surgeon's experience. Despite wear and high revision rates, the technically mature artificial sphincter produces excellent continence results and has become the gold standard in the therapy of male stress urinary incontinence. The circumferential and continuous urethral compression by the cuff is highly effective, but at the price of an almost inevitable urethral atrophy. To overcome this problem, various surgical techniques have been developed (tandem cuff, cuff downsizing, transcorporal cuff placement). However, the expensive artificial sphincter is not a nostrum for every incontinent man, since it requires certain minimal cognitive and manual capabilities. Therefore, the search for less demanding treatment alternatives seems to be necessary, even if one has to accept lower continence rates.

Abstract
Therapy of superficial bladder tumors is transurethral resection (TUR), and in cases of pT1 or high-grade tumors a re-TUR is indicated. Patients with carcinoma in situ receive intravesical chemotherapy or BCG for at least 3 months. Persistent carcinoma in situ may be treated by radical cystectomy. With the provision of a functionally adequate urinary diversion, cystectomy represents an effective treatment for patients with muscle-invasive bladder cancer without metastatic spread. Regional lymph node metastases can be found in up to 15% of stage T1 disease and are present in 33% of stage T3/4 lesions. Thus, lymphadenectomy gains diagnostic and possibly also therapeutic importance. For selected patients, who cannot be treated by radical cystectomy, multimodal concepts aiming to preserve the bladder are discussed. After or prior to cystectomy systemic chemotherapy may become necessary for some patients to positively affect the course of the disease in cases of locally advanced or metastatic lesions.

Abstract
We report the first case of direct surgical injury to a pudendal nerve branch during radical perineal prostatectomy. A 65-year-old patient presented with typical symptoms of a pudendal nerve lesion after radical perineal prostatectomy. As the patient did not respond to conservative treatment, surgical exploration and exeresis of the injured sensory branch of the pudendal nerve was necessary, resulting in pain improvement. Urologic surgeons should be aware of the typical symptoms after iatrogenic injury to the pudendal nerve or its branches. Early diagnosis and neurosurgical intervention are important to obtain a more favorable outcome.

Abstract
The purpose of this study was to test the hypothesis that renal cell carcinoma (RCC) exhibits an increased intratumoral interstitial fluid pressure (IT-IFP). Therefore, resected tumors from human primary (n = 23) or metastatic RCC (n = 3) were xenografted in SCID mice. The IFP of single tumor nodules (n = 65) and normal mouse tissue (n = 195) was measured by means of the "wick-in-needle" technique. Data demonstrate that the mean IT-IFP at neoplasia was 35 times greater than in normal tissue, and decreased precipitously at the tumor boundary. IT-IFP values tended to increase with the grade of malignancy of the tumor cells and tumor size. The mean IT-IFP of xenografts derived from primary RCC was twice as high as that from metastatic RCC tissue. These findings indicate a biophysical barrier to drug delivery in RCC; this may, in concert with cellular-based drug resistance mechanisms, be an additional explanation for resistance of the tumor to certain blood-borne anticancer therapies.
