High magnification cystoscopy in the primary diagnosis of bladder tumors.

Purpose of reviewIn bladder cancer, discrimination between benign and malignant tissue may remain tricky with current endoscopic tools. On the basis of our recent experience with high-magnification cystoscopy, compared with other tools such as optical coherence tomography or confocal laser endomicroscopy, it is suggested here that this discrimination may well be feasible endoscopically. The clinical potential of these systems that are being developed as complementary tools to the current endoscopic equipment is reviewed.Recent findingsAt present, white-light cystoscopy, either assisted by fluorescence cystoscopy or narrow-band imaging, is proposed for the global cystoscopic examination of bladder cancer patients. Both techniques compete to help to reduce the recurrence rate by improving exophytic tumor detection, and the extent of carcinoma in situ and high-grade dysplasia. All of which are important prognosis factors for disease progression. In addition, recent findings on neoangiogenesis that accompanies early stage bladder cancer show that this may also be an important observable switch in bladder cancerogenesis, as it is found very early in tumor development. The high magnification cystoscopy as a complementary tool to fluorescence cystoscopy allows classification of the vessel patterns on fluorescence positive sites, and thus facilitates the discrimination between cancerous and noncancerous lesions. This information may be useful to reduce the false positive rate of fluorescence cystoscopy.SummaryEmerging technologies aiming at a real-time in-situ discrimination between benign and malignant tissue during endoscopic bladder exploration is a promising development for the monitoring of bladder cancer patients.

Socio-demographic predictors of high support needs in newly diagnosed breast cancer patients.

GRIESSER A.-C., VLASTOS G., MOREL L., BEAUME C., SAPPINO A.-P. & HALLER G. (2010) European Journal of Cancer Care Socio-demographic predictors of high support needs in newly diagnosed breast cancer patients This study aimed to identify high support needs and their socio-demographic predictors to improve supportive care for newly diagnosed breast cancer patients. A cross-sectional study measured patients' needs and unsatisfied support needs by the supportive care needs survey (SCNS-34), administered after surgery, chemotherapy or radiotherapy. Socio-demographic, disease and treatment characteristics completed data collection. A total of 308 questionnaires were completed with a response rate of 88%. The most frequent support needs (73.3% of patients) related to information and the highest unsatisfied support needs to the management of emotions and daily life (36.3-39.6% of patients). Younger age predicted high and dissatisfied support needs (P < 0.05). Patients born outside Switzerland or with a lower level of education had more needs in daily living and psychological domains (P < 0.05). Being born outside Switzerland also predicted dissatisfaction with information provided. Being parent was a predictor of significant needs in the daily living domain after adjusting for disease and treatment characteristics (P= 0.01). Therefore, information, psychological and daily living support for newly diagnosed breast cancer patients should be strongly reinforced, particularly in patients being born outside Switzerland, those with children or being younger. For the latter, support in sexuality domain should also be emphasised.

Treatment of advanced soft-tissue sarcomas using a combined strategy of high-dose ifosfamide, high-dose doxorubicin and salvage therapies.

Having determined in a phase I study the maximum tolerated dose of high-dose ifosfamide combined with high-dose doxorubicin, we now report the long-term results of a phase II trial in advanced soft-tissue sarcomas. Forty-six patients with locally advanced or metastatic soft-tissue sarcomas were included, with age <60 years and all except one in good performance status (0 or 1). The chemotherapy treatment consisted of ifosfamide 10 g m(-2) (continuous infusion for 5 days), doxorubicin 30 mg m(-2) day(-1) x 3 (total dose 90 mg m(-2)), mesna and granulocyte-colony stimulating factor. Cycles were repeated every 21 days. A median of 4 (1-6) cycles per patient was administered. Twenty-two patients responded to therapy, including three complete responders and 19 partial responders for an overall response rate of 48% (95% CI: 33-63%). The response rate was not different between localised and metastatic diseases or between histological types, but was higher in grade 3 tumours. Median overall survival was 19 months. Salvage therapies (surgery and/or radiotherapy) were performed in 43% of patients and found to be the most significant predictor for favourable survival (exploratory multivariate analysis). Haematological toxicity was severe, including grade > or =3 neutropenia in 59%, thrombopenia in 39% and anaemia in 27% of cycles. Three patients experienced grade 3 neurotoxicity and one patient died of septic shock. This high-dose regimen is toxic but nonetheless feasible in multicentre settings in non elderly patients with good performance status. A high response rate was obtained. Prolonged survival was mainly a function of salvage therapies.

High altitude journeys and flights are associated with the increased risk of flares in IBD patients

Background: There is increasing evidence that hypoxia induces inflammation in the gastrointestinal tract. The clinical impact of hypoxia in patients with inflammatory bowel disease (IBD) is so far poorly investigated. Aim: We wanted to evaluate if flights and journeys to regions >= 2000 meter above sea level are associated with the occurrence of flares in IBD patients in the following 4 weeks. Methods: A questionnaire was completed by inpatients and outpatients of the IBD clinics of three tertiary referral centers presenting with an IBD flare. Patients were inquired about their habits in the 4 weeks prior to the flare. Patients with flares were matched with an IBD group in remission during the observation period (according to age, gender, smoking habits, and medication). Results: A total of 103 IBD patients were included (43 Crohn's disease (CD), whereof 65% female, 60 ulcerative colitis, whereof 47% female, mean age 39.3 ± 14.6 years for CD and 43.1 ± 14.2 years for UC). Fifty-two patients with flares were matched to 51 patients without flare. Overall, IBD-patients with flares had significantly more frequently a flight and/or journey to regions >= 2000 meters above sea level in the observation period compared to the patients in remission (21/52 (40.4%) vs. 8/51 (15.7%), p = 0.005). There was a statistically significant correlation between the occurrence of a flare and a flight and/or journey to regions >= 2000 meters above sea level among CD patients with flares as compared to CD patients in remission (8/21 (38.1%) vs. 2/22 (9.1%), p = 0.024). A trend for more frequent flights and high-altitude journeys was observed in UC patients with flares (13/31 (41.9%) vs. 6/29 (20.7%), p = 0.077). Mean flight duration was 5.8 ± 4.3 hours. The groups were controlled for the following factors (always flare group cited first): age (39.6 ± 13.4 vs. 43.5 ± 14.6, p = 0.102), smoking (16/52 vs. 10/51, p = 0.120), regular sports activities (32/52 vs. 33/51, p = 0.739), treatment with antibiotics in the 4 weeks before flare (8/52 vs. 7/51, p = 0.811), NSAID intake (12/52 vs. 7/51, p = 0.221), frequency of chronic obstructive pulmonary disease (both groups 0) and oxygen therapy (both groups 0). Conclusion: IBD patients with a flare had significantly more frequent flights and/or high-altitude journeys within four weeks prior to the IBD flare compared to the group that was in remission. We conclude that flights and stays in high altitude are a risk factor for IBD flares.
