RESUMO

OBJECTIVE: The study explores challenges, competencies, and helpful support in coping with the disease of patients with breast cancer and gynaecological cancer and how patient competence as an interaction of these factors might be promoted. METHODS: Semi-structured interviews were conducted with 19 patients in acute care, 20 patients undergoing rehabilitation, and 16 participants in a self-help group and evaluated using qualitative content analysis. RESULTS: The challenges are summarised in the main categories - diagnosis processing, treatment/recurrence fears, illness processing and adaptation, worries about relatives, reactions of the social environment, and worries about the workplace. The named personal competencies in dealing with these challenges were assigned to the following main categories: cognition-related coping, action-related coping, self-regulation illness processing, obtaining and accepting support, self-determined communication of the illness, identifying and applying helpful strategies, illness-related experience, favourable life circumstances, openness to offers of help. Helpful emotional, informational or instrumental support is perceived by relatives, friends, animals, colleagues/employers, treatment providers, rehabilitation, fellow patients, self-help, and counselling facilities. DISCUSSION: The women describe a variety of competencies, which corresponds to a needs-oriented, self-directed coping process. The individuality and complexity of the interaction of the components of patient competence underline the relevance of patient-oriented care. Empowerment and an active patient role are necessary to promote their coping skills according to their needs. Support from practitioners or the private environment can reduce challenges or promote competencies and application.

RESUMO

OBJECTIVES: This study aimed to investigate challenges, competencies, and support in breast and gynecological cancer patients when dealing with information needs and how health literacy as an interplay of these factors might be improved. METHODS: Semi-structured interviews were conducted with patients in acute care (n = 19), undergoing rehabilitation (n = 20) or attending self-help groups (n = 16). Interviews were analyzed using content analysis. RESULTS: Challenges: gain information according to own needs, internet as information source, information evaluation and decisions, doctor-patient communication, situationally limited information processing, difficult access to information. Competencies: self-regulation of information needs, media and social competencies, communication skills in the doctor-patient conversation, internet competencies, self-directed decisions according to own needs, interest/self-efficacy, previous knowledge, trust in the doctor. SUPPORT: by professionals (e.g., patient-centered communication), relatives (e.g., support during consultations), peers (e.g., exchange), facilities (e.g., clinics). CONCLUSIONS: Our findings provide insight into challenges and competencies relevant to patients' health literacy and the influence of support. The individuality of the interplay highlights the relevance of an active patient role and patient-centered care. PRACTICE IMPLICATIONS: Patients' health literacy should be improved in (psycho)oncological work by both reducing challenges (e.g., by communication skills training, involving relatives) and promoting competencies (e.g., by needs- and competence-oriented information offers).

RESUMO

BACKGROUND: Among patients with breast or gynecological cancer, supportive care needs are both highly prevalent and enduring. However, little is known about whether meeting patients' needs is accompanied by increased quality of life (QoL). We aimed to explore patients' supportive care needs reported at the beginning of inpatient rehabilitation and examined whether meeting these needs resulted in improved QoL. MATERIAL AND METHODS: In a multicenter, prospective cohort study with 2 measurement occasions (beginning and end of inpatient rehabilitation), 292 patients with breast and gynecological cancer (mean age 55 years; 71% breast cancer) were enrolled. In 73%, time since diagnosis was longer than 6 months. We obtained self-reports of supportive care needs in 12 domains and measured QoL using the EORTC QLQ-C30 functioning subscales. RESULTS: At the beginning of inpatient rehabilitation, top-ranking severe supportive care needs concerned coordination of care (48%), medical information (45%), alleviation of physical symptoms (42%) and support with improving health behaviors (36%). At the end of inpatient rehabilitation, all needs assessed declined significantly, although many patients still expressed strong needs in some domains. However, meeting patients' needs was accompanied by improvements in all functioning subscales. CONCLUSIONS: This is the first study to show that meeting breast and gynecological cancer patients' supportive care needs during inpatient rehabilitation resulted in improved QoL. Given the considerable proportions of patients still reporting unmet needs at the end of their stay, stronger and continuing efforts seem warranted to meet these needs and thus further increase QoL.

RESUMO

Androgen deprivation is a common treatment option in patients with locally advanced or metastatic prostate cancer. No case of long term treatment with an intermittent approach with only low dose bicalutamide (50 mg daily) has been described yet. We report a 60-year-old patient, initially presenting with a PSA elevation of 19.2 ng/mL in 1996. After diagnosis of well to moderately differentiated prostate cancer by transrectal biopsy, the patient underwent an open radical prostatectomy. Final diagnosis was adenocarcinoma of the prostate, classified as pT3a, pR1, pV0, and pL1. Adjuvant intermittent androgen deprivation therapy with flutamide 250 mg was applied, which was changed to bicalutamide 50 mg once daily when it became available in 2001. Six on-phases were performed and PSA values never exceeded 20 ng/mL. The patient did not experience any serious side effects. To date, there are no clinical or radiological signs of progression. Current PSA value is 3.5 ng/mL.

RESUMO

BACKGROUND: Uro-oncological neoplasms have both a high incidence and mortality rate and are therefore a major public health problem. The aim of this study was to evaluate research activity in uro-oncology over the last decade. METHODS: We searched MEDLINE and ClinicalTrials.gov systematically for studies on prostatic, urinary bladder, kidney, and testicular neoplasms. The increase in newly published reports per year was analyzed using linear regression. The results are presented with 95% confidence intervals, and a p value <0.05 was considered statistically significant. RESULTS: The number of new publications per year increased significantly for prostatic, kidney and urinary bladder neoplasms (all <0.0001). We identified 1,885 randomized controlled trials (RCTs); also for RCTs, the number of newly published reports increased significantly for prostatic (p = 0.001) and kidney cancer (p = 0.005), but not for bladder (p = 0.09) or testicular (p = 0.44) neoplasms. We identified 3,114 registered uro-oncological studies in ClinicalTrials.gov. However, 85% of these studies are focusing on prostatic (45%) and kidney neoplasms (40%), whereas only 11% were registered for bladder cancers. CONCLUSIONS: While the number of publications on uro-oncologic research rises yearly for prostatic and kidney neoplasms, urothelial carcinomas of the bladder seem to be neglected despite their important clinical role. Clinical research on neoplasms of the urothelial bladder must be explicitly addressed and supported.

RESUMO

PURPOSE: Cancers complicating organ allografts are a major cause of morbidity and mortality after renal transplantation. Different registries have described an overall three to eightfold increase in cancer risk compared with the general population. This retrospective study investigated the incidence and outcome of de novo malignancies following kidney transplantation in a single German kidney transplantation center. MATERIALS AND METHODS: Between 1966 and 2005, 1882 patients underwent kidney transplantation at the Erlangen-Nuremberg kidney transplantation center. The incidence and types of post-transplant malignancies were retrospectively analyzed according to the patients' records and the database of the local cancer registry. RESULTS: We identified 257 malignancies in 231 patients, an overall incidence of 13.7%. The mean follow-up time was 9.9 yr (range, 0.4-25.5 yr). The observed incidence data corresponded to a 12.1-fold increase in the overall risk of developing a malignant nonskin tumor compared with the nontransplanted population. Urinary tract malignancies represented the most frequent malignancies among the nonskin tumors (32.1%), followed by gastrointestinal tract (30.7%) and gynecological (14%) cancers. When we considered the duration from renal transplantation to tumor detection and tumor-specific survival, there was no difference between patients treated with or without a cyclosporine A-based regimen. CONCLUSIONS: In our study, the overall risk of developing a post-transplant nonskin malignancy was 12.1-fold higher compared with the age-matched general population. Development of solid organ malignancies is one of the most frequent causes of morbidity and mortality in renal transplant recipients; thus, close tumor screening in patients after kidney transplantations is warranted.

RESUMO

INTRODUCTION: Renal cell carcinoma (RCC) is characterized by intense angiogenesis with hyperexpression of proangiogenic factors. This study explored the potential of dynamic tissue perfusion measurement (DTPM) to detect differences in tissue perfusion between kidneys with RCC and corresponding healthy kidneys. PATIENTS AND METHODS: 30 patients with unilateral, histologically confirmed RCC underwent DTPM by color Doppler ultrasound. Before scheduled surgery, Doppler ultrasound data were acquired from four transverse areas of the affected kidney and the contralateral healthy kidney. Doppler ultrasound data were recorded over a 10-second period and characteristic tissue perfusion parameters were determined. RESULTS: The kidneys with RCC displayed characteristic changes in perfusion parameters. A significant increase in signal intensity and a significant decrease in flow resistance were noted. A combination of several DTPM parameters was used to distinguish correctly between kidneys bearing RCC or healthy kidneys with up to 75% accuracy. There was no association between the perfusion parameters and the pathological characteristics of the respective tumors. CONCLUSIONS: DTPM is a promising tool for the evaluation of whole-organ tissue perfusion. This study demonstrates the feasibility of performing DTPM measurements in kidneys bearing RCC lesions. In tumors that are characterized by extensive neovascularization, this method has the potential to be a valuable diagnostic tool.

RESUMO

OBJECTIVES: To introduce a simplified technique for MRI-guided core biopsies (MRGB) of the prostate in the supine position using large-bore magnet systems. METHODS: Fifty men with a history of negative transrectal ultrasound-guided biopsies underwent MRGB in either a 1.5-T (13/50) or 3.0-T (37/50) wide-bore MRI unit. MRGBs were conducted with the patients in a supine position using a dedicated MR-compatible biopsy device. RESULTS: We developed a dedicated positioning device for the supine position. Using this device, the biopsies were performed successfully in all patients. Apart from minor rectal bleeding, only one patient developed a major side effect (urosepsis). Histology revealed prostate cancer in 25/50 (50 %) patients. CONCLUSIONS: The new technique appears feasible. Its major advantage is the more comfortable and patient-friendly supine position during the biopsy without the need to modify the MRI system's patient table. KEY POINTS: • A novel positioning device for MRI-guided prostate biopsies has been developed. • Biopsies can be performed in the patient-friendly supine position. • The positioning device can be utilised without modifying the MRI's patient table.

RESUMO

BACKGROUND: Recent studies have underlined the role of nuclear receptors in the involvement of prostate cancer signalling pathways. PATIENTS AND METHODS: A total of 84 benign prostate hyperplasia (BPH), 84 low risk prostate cancer (LPC) and 64 advanced disease (APC) cases were sampled on a tissue microarray (TMA) and stained for retinoic acid receptor (RAR)-α, retionoid X receptor (RXR)-α, liver X receptor (LXR)-α, farnesoid X receptor (FXR) and proliferate-activated receptor gamma (PPAR)-γ and the (pro)-inflammatory molecules cyclooxygenase 2 (COX2), tumor necrosis factor (TNF)-α and inducible Nitric oxide synthase (iNOS) immunohistochemically. RESULTS: PPAR-γ expression in APC tissues was found to be significantly higher than that in LPC and BPH specimens (p<0.001). In contrast, RXR-a expression was significantly lower (p<0.001). COX2 staining demonstrated a trend towards overexpression in APC (p=0.025). No significant differences were found for RAR-α, iNOS and TNF-α expression. Staining of FXR and LXR was seen diffusely in the cytoplasm as well as in the nucleus, preventing sufficient evaluation by definition. CONCLUSION: This study provides the basis for applying PPAR-γ ligands clinically in treatment of APC.

RESUMO

AIM: To explore the potential of transrectal magnetic resonance image- (MRI-) guided biopsies of the prostate in a patient cohort with prior negative ultrasound guided biopsies. PATIENTS AND METHODS: Ninety-six men with suspected prostate cancer underwent MRI-guided prostate biopsies under real-time imaging control in supine position. RESULTS: Adenocarcinoma of the prostate was detected in 39 of 96 patients. For individual core biopsies, MRI yielded a sensitivity of 93.0% and a specificity of 94.4%. When stratifying patients according to the free-to-total prostate-specific antigen (PSA) ratio, the prostate cancer discovery rate was significantly higher in the group with ratios less than 0.15 (57.1%). CONCLUSION: MRI-guided biopsy of the prostate is a diagnostic option for patients with suspected prostate cancer and a history of repeatedly negative transrectal ultrasound-guided biopsies. Combined with the free-to-total PSA ratio, it is a highly effective method for detecting prostate cancer.

RESUMO

Plasmacytoid urothelial carcinoma of the bladder represents a rare and aggressive variant of urothelial carcinoma, which is usually diagnosed at an advanced pathologic stage. Until now, no reports exist on this rare tumor type in the upper urinary tract. Herein, we present the first report on the clinical course of a metastatic plasmacytoid urothelial carcinoma of the renal pelvis and show its unfavorable outcome despite multimodal therapy.

RESUMO

UNLABELLED: Transurethral resection of bladder tumour (TURBT) is the 'gold standard' in the diagnosis and therapy of non-muscle-invasive bladder cancer. To improve the quality of this technique an additional TUR (after 4-6 weeks) or a simultaneous photodynamic diagnosis is often offered. The present study shows different variables that influence, to a greater or lesser extent, the accuracy of the TUR diagnosis and the success of the operation. This is very important for the further management of bladder cancer, be it in tumour follow-up or in preparation for more invasive therapies. OBJECTIVE: To analyse the impact of a standardised extended transurethral resection of bladder tumour (TURBT) protocol on the determination of the residual tumour status at initial TURBT session and recurrence rate in the primary resection area. Despite, the fact that there is a clear consensus on the aims of TURBT, there is little agreement on how to perform TURBT to achieve that goal. PATIENTS AND METHODS: We retrospectively evaluated 221 consecutive patients, who underwent 305 TURBT sessions for bladder cancer, including patients with recurrent tumours. All the TURBTs were extended by taking additional deep and marginal specimens, according to a standardised protocol. Clinical and histopathological data were retrieved from the patients' records. RESULTS: Across all tumour stages, residual tumour (pR1) was found in 38% of the additionally taken specimens. There was a significant association of pR1 status with tumour stage, grade, and size. Also in the group of non-muscle-invading tumours, the rate of R1 resection was rather high at 22%. There was no association with focality and the training status of the surgeon. At follow-up, of all the patients with a unifocal primary tumour there was recurrence in the same area as the primary in 5.1%. CONCLUSIONS: Extended TURBT provides detailed information about the horizontal and vertical extent of the bladder tumour. The implementation of standardised TURBT procedures, such as our protocol of an extended TURBT, is greatly needed to improve local tumour control. Whether a diagnostic re-TUR may be restricted to those cases with positive margins or ground specimens remains to be studied.

RESUMO

We present a case of high-flow priapism due to perineal trauma and subsequent arteriocavernosal fistula, which was diagnosed by sonography. Selective arterial embolization led to complete detumescence without compromising the patient's erectile function. Color Doppler sonography is an appropriate diagnostic tool to diagnose arteriocavernosal fistula. Selective arterial embolization is a safe and effective therapeutic option.

RESUMO

INTRODUCTION: Reporting guidelines aim to ensure adequate and complete reporting of clinical studies and are an indispensable tool to translate scientific results into clinical practice. The extent to which reporting guidelines are incorporated into the author instructions of journals publishing in the field of urology remained unclear. MATERIALS AND METHODS: We assessed the author instructions of uro-nephrological journals indexed in 'Journal Citation Reports 2009'. Two authors independently assessed the author guidelines. We evaluated additional information including whether a journal was published by or in association with a medical association. Discrepancies were resolved by re-checking the respective author instructions and by discussion with a third author. RESULTS: The recommendations of the International Committee of Journal Editors were endorsed by 32 journals (58.2%) but were mentioned in 12 (37.5%) only to give general advice about manuscript preparation. Fourteen journals (25.5%) mentioned at least one reporting guideline, with CONSORT the most frequently cited. Journals with high impact factors were more likely to endorse CONSORT (p < 0.009). Other reporting guidelines were mentioned by <6% of the journals. CONCLUSION: All key stakeholders involved in the publication process should more frequently promote the awareness and use of reporting guidelines.

RESUMO

PURPOSE: Standard treatment for superficial bladder cancer is transurethral resection of the bladder tumor (TURBT) followed by intravesical therapy. Little is known about the biologic behavior and treatment response of superficial disease within an irradiated bladder. We specifically analyzed patients who developed superficial recurrence after TURBT and radiotherapy or radiochemotherapy. PATIENTS AND METHODS: Between 1982 and 2006, a total of 531 consecutive patients with invasive bladder cancer were treated by using various bladder-sparing protocols at our institution. Of these, 389 (76%) achieved a complete response after TURBT and radiotherapy/radiochemotherapy. During follow-up, 68 of 389 patients (17%) developed a superficial local relapse (< or = T1) and form the subject of this study. RESULTS: Sixty-four of 68 patients underwent conservative TURBT with or without intravesical treatment (4 patients underwent immediate cystectomy): 31 of 64 patients (48%) had no further bladder recurrence, 21 (33%) experienced additional superficial recurrences, and 12 (19%) ultimately progressed to muscle-invasive disease. Disease-specific survival rates were 87% and 72% at 5 and 10 years, respectively. Compared with 255 patients without local bladder relapse after primary treatment, no significant difference was found for disease-specific survival rates (72% after superficial vs. 79% without local relapse at 10 years, p = 0.78). However, significantly fewer patients with a superficial relapse survived with their native bladder (50% after superficial vs. 76% without local relapse at 10 years, p < 0.001). CONCLUSION: A further bladder-sparing approach with TURBT and intravesical therapy is reasonable for patients with superficial relapse after combined-modality treatment without compromising survival. However, these patients are at greater risk of requiring late cystectomy.

RESUMO

The inhibitor of apoptosis protein survivin is of critical importance for regulation of cellular division and survival. Published data point to a restricted function of survivin in embryonic development and cancer; thus survivin has been broadly proposed as an ideal molecular target for specific anti-cancer therapy. In contrast to this paradigm, we report here broad expression of survivin in adult differentiated tissues, as demonstrated at the mRNA and protein levels. Focusing on the kidney, survivin is strongly expressed in proximal tubuli, particularly at the apical membrane, which can be verified in rat, mouse, and human kidneys. In the latter, survivin expression seems to be even stronger in proximal tubuli than in adjacent cancerous tissue. Primary and immortalized human renal tubular cells also showed high levels of survivin protein expression, and RNA interference resulted in a partial G(2)/M arrest of the cell cycle and increased rate of apoptosis. In conclusion, survivin may be of importance for renal pathophysiology and pathology. The predominant apical expression of survivin may indicate a further, yet unknown, function. Interventional strategies to inhibit survivin's function in malignancy need to be carefully (re)evaluated for renal side effects, as well as for other possible organ dysfunctions.

RESUMO

PURPOSE: To investigate whether the addition of chemotherapy to radiotherapy (RT) is beneficial particularly in bladder tumors that possess the capacity for rapid proliferation. PATIENTS AND METHODS: The Ki-67 index was evaluated by immunohistochemistry on pretreatment biopsies from 136 patients treated by transurethral tumor resection (TURBT) and RT (n=50) or platin-based radiochemotherapy (RCT; n=86). Ki-67 expression was correlated with response to RT/RCT and long-term local control rates. The median follow-up was 43 months. RESULTS: The percentage of Ki-67-positive cells ranged from 1.5% to 89%. Complete response (CR) was observed in 100/131 patients (76%, five without restaging TURBT). A statistically significant association between high Ki-67 index (>or= median) and CR was noted for patients receiving RCT (93% vs. 66% for Ki-67 < median; p=0.001), but not for patients treated with RT alone (p=0.12). Long-term local control was 39% for patients treated with RT, and 44% for patients after RCT (p=0.49). Patients with high Ki-67 index did significantly better when subjected to combined RCT (55% vs. 33% with low Ki-67 index; p=0.006), whereas no difference between high and low Ki-67 status was observed in the RT group (39% each; p=0.57). On multivariate analysis, Ki-67 status was an independent predictor for local failure in the RCT group (risk ratio, 0.43; p=0.007). Disease-specific survival was significantly better after RCT (62%) as compared with RT (42%; p=0.03), however, the Ki-67 index was not related to this endpoint. CONCLUSION: Rapid proliferation is associated with improved local control, if patients are treated with concurrent RCT. The cytostatic effect of concurrent chemotherapy may effectively inhibit repopulation during fractionated RT.

RESUMO

PURPOSE: To give an update on the long-term outcome of an intensified protocol of combined radiochemotherapy (RCT) with 5-fluorouracil (5-FU) and cisplatin after initial transurethral resection of bladder tumor (TURBT) with selective organ preservation in bladder cancer. METHODS AND MATERIALS: One hundred twelve patients with muscle-invading or high-risk T1 (G3, associated Tis, multifocality, diameter >5 cm) bladder cancer were enrolled in a protocol of TURBT followed by concurrent cisplatin (20 mg/m(2)/day as 30-min infusion) and 5-FU (600 mg/m(2)/day as 120-h continuous infusion), administered on Days 1-5 and 29-33 of radiotherapy. Response to treatment was evaluated by restaging TURBT 4-6 weeks after RCT. In case of invasive residual tumor or recurrence, salvage cystectomy was recommended. RESULTS: Ninety-nine patients (88.4%) had no detectable tumor at restaging TURBT; 71 patients (72%) have been continuously free from local recurrence or distant metastasis. Superficial relapse occurred in 13 patients and muscle-invasive recurrence in 11 patients. Overall and cause-specific survival rates for all patients were 74% and 82% at 5 years, respectively. Of all surviving patients, 82% maintained their own bladder, 79% of whom were delighted or pleased with their urinary condition. Hematologic Grade 3/4 toxicity occurred in 23%/6% and Grade 3 diarrhea in 21% of patients. One patient required salvage cystectomy due to a shrinking bladder. CONCLUSION: Concurrent RCT with 5-FU/cisplatin has been associated with acceptable acute and long-term toxicity. Overall and cause-specific survival rates are encouraging. More than 80% of patients preserved their well-functioning bladder.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the suitability of MR Spectroscopy in screening for prostate cancer in comparison to T2-weighted MR imaging. MATERIALS AND METHODS: Forty-six patients with biopsy confirmed prostate cancer underwent combined endorectal-body-phased-array MRI at 1.5T (Tesla). Twelve patients were additionally examined with 3D-spectroscopy sequence. The results of the spectroscopy were compared with the findings of T2-weighted MR imaging and the histological examination of radical prostatectomy specimens. RESULTS: With 3D-spectroscopy, a choline+creatine/citrate-ratio of 0.45 for healthy tissue and a ratio of 1.90 for tumor tissue were found and a significant difference between the groups was demonstrated. In 6 cases diagnosis of tumor localization was improved with spectroscopy in comparison with T2-weighted imaging alone. CONCLUSION: 3D-spectroscopy is a suitable technique for improving MR imaging of prostate cancer. This method can improve the diagnostic accuracy of T2-weighted imaging alone. At present, 3D-CSI spectroscopy alone can not be recommended with sufficient validity.

RESUMO

Non-invasive methods for detecting genetic alterations of bladder cancer are increasingly becoming the focus of attention as diagnostic tools. The fluorescence in situ hybridization we performed to detect genetic alterations of chromosomes 3, 7, 9p21, and 17 (UroVysion Test) showed very high sensitivity, higher even than cytology, in detecting bladder tumors of varying differentiation (pTa-pT4). The use of this test in everyday clinical urology can be a very useful decision aid in treating problem cases. A pT1G3 bladder carcinoma in the presence of multichromosomal alterations should be treated as a muscle-invasive pT2 tumor. Other superficial bladder tumors (pTaGI-III, pT1GI-II) with negative histopathology in follow-up and positive FISH analysis with the UroVysion Test should have bladder mapping performed again. Although FISH analysis is currently the most sensitive marker for bladder tumors, the elaborate handling, the cost of the DNA probes and the laboratory equipment required, limit the use of this method in the urologist's everyday routine.
