Carcinoma uroteliale in cisti pielogena
Urothelial carcinoma in a pyelocaliceal cyst
Renal complex cysts are lesions whose nature can be either benign or malignant. Depending on the presence of
septa, solid components, enhancement or calcifications, they are distinguished according to the Bosniak classi-
fication based on CT findings, as well as MRI and ETG. We report a rare case of urothelial carcinoma, originating
over a pyelocalyceal cyst in a 50-year-old man, and classified as Bosniak IIF by CT and MRI investigations
Mitomycin C from birth to adulthood
Mitomycin C (MMC) intravesical therapy for "superficial" papillary bladder tumors was firstly introduced in the early seventies with promising results. In the following years, several pharmacokinetic studies investigated its mechanism of action to optimize the intravesical administration. Numerous studies confirmed thereafter both the ablative and the prophylactic efficacy and the low toxicity of MMC when intravesically given. In 1984, a complete response rate of 42% in 60 patients not responsive to thiotepa was reported with intravesical MMC at the dose of 40 mg diluted in 40 ml for 8 weeks. In the following decades, many large randomized studies showed the benefit of intravesical prophylaxis with MMC versus transurethral resection (TUR) alone. Since 2002, the role of adjuvant intravesical chemotherapy and of an early MMC instillation in preventing recurrence compared with TUR alone has been confirmed by large meta-analyses and stated by the European Association of Urology (EAU) guidelines. The need for further intravesical chemotherapy after the early instillation in patients at intermediate-high risk of recurrence has been proved by several trials. Although intravesical Bacillus Calmette-Guerìn (BCG) is considered the best choice for high-risk patients and MMC for the low-risk group, both MMC and BCG can be given to prevent recurrence in intermediate-risk patients. However, the higher efficacy of BCG over MMC is evident only if maintenance regimen is administered. Despite its proven efficacy, immediate intravesical MMC is not yet fully entered in common clinical practice and efforts should be made by the urologists to optimize its adoption
Does the Compliance to Intravesical BCG Differ between Common Clinical Practice and International Multicentric Trials?
INTRODUCTION:
The aim of this study was to analyze the reasons for intravesical BCG interruption in clinical practice. BCG for at least one year is advocated as the best regimen to treat high-risk non-muscle invasive bladder cancer (NMIBC). However, almost 50% of patients don't complete it. Toxicity accounts for 10% of dropouts in international trials.
MATERIALS AND METHODS:
Patients with T1HG NMIBC undergoing 1-year BCG were enrolled in this study. BCG was administered for one year. Toxicity and causes of treatment interruption were recorded.
RESULTS:
A total of 411 patients were enrolled in the study. Out of these total number of patients, 380 (92.5%) completed the induction cycle and 215 (52.3%) completed one year. Toxicity requiring interruption or postponement was recorded in 25 (6.1%) and 60 (14.6%) patients. Ninety-three patients (30.2%) stopped BCG, 9 (9.7%) for recurrence and 14 (15.1%) for grade-3 toxicity. Intriguingly, 55 (59.1%) patients refused BCG due to mild discomfort and deterioration in quality of social life.
CONCLUSIONS:
Grades 2-3 toxicity causes BCG interruption in a few cases. Almost 60% of interruptions are attributable to persistent grade-1 toxicity, which is inadequately treate
Genitourinary Symptoms-Patient Help-Seeking and General Practitioner Management: An Outpatient Based Survey at a Tertiary Hospital in Southern Italy
Introduction: General knowledge of most common genitourinary diseases is often lacking. In this survey we evaluated the attention given by patients and general practitioners to genitourinary symptoms, and particularly to hematuria and potential early signs of genitourinary cancer. Methods: A structured self-administered questionnaire was administered to outpatients before the urological consultation. The questionnaire consisted of 4 multiple choice questions to record the level of patient awareness of urological symptoms, the importance given to gross hematuria, the interval between the onset and the visit, the regularity of physical examination and the first-level investigations indicated by the general practitioner before the urological consultation. Results: A total of 327 self-administered questionnaires were obtained from 358 consecutive patients for a compliance rate of 91.3%. Asymptomatic gross hematuria was present in 91 cases (27.8%). The first episode of hematuria was not reported by 20% of the patients, with a median delay of 11 months. Only 77 patients (23.6%) in the last 5 years had received a physical examination including the external genitalia. Laboratory and/or imaging investigations were indicated before urological counseling in 172 (52.6%) patients. Conclusions: The majority of patients underestimated urological symptoms. Less than 25% and 50% of patients had a physical examination and first-level investigations performed before urological counseling, respectively. Our survey reveals an important lack of awareness of genitourinary symptoms that could be responsible for delayed diagnosis and inappropriate treatment
MULTI-ISTITUTIONAL CONTROLLED STUDIES DO NO REFLECT THE PATIENT’S COMPLIANCE TO BCG ENCOUNTERED IN CLINICAL PRACTICE. RESULTS ON 411 PATIENTS
INTRODUCTION AND OBJECTIVES
BCG maintenance for at least one year is advocated by urological guidelines as the best intravesical regimen in high-risk non muscle invasive bladder cancer (NMIBC), conservatively treated. Noteworthy, a relevant percentage of patients does not complete the planned treatment. The aim of this study was to analyze the reasons for treatment interruption and low compliance.
METHODS
Consecutive patients affected by T1HG NMIBC undergoing conservative management with adjuvant BCG entered the study. The Connaught BCG strain was administered intravesically according to the South West Oncology Group schedule for one year, 81mg diluted in 50 ml of saline solution, starting 21-30 days after TUR. Toxicity and causes of treatment interruption were recorded.
RESULTS
Between 2000 and 2012, intravesical BCG with 1-year maintenance regimen was proposed to 411 patients. Out of them, 380 (92,5%) completed the induction cycle and 308 (81%) started the maintenance. A total of 215 (52.3%) completed the scheduled one-year treatment. Toxicity requiring treatment interruption was recorded in 25 (6.1%) patients only. In 60 patients (14.6%) a delay of one or more instillations was necessary. Grade-I toxicity, not requiring therapy interruption or delay, was recorded in 193 (46.9%) cases. In our experience, the patient's compliance registered during the induction cycle reached 92%, confirming the low toxicity and the good patients' acceptance of the 6-week induction. However, between the end of the induction course and the first maintenance instillation, 50 patients (13%) became reluctant to treatment for many personal reasons unrelated to toxicity and 22 (6%) were excluded for suspicious bladder lesion at cystoscopy. Moreover, patients' compliance to maintenance decreased from 81% at 3 months to 56.6% at 12 months. Surprisingly, the rate of drop-out (15%) remained stable at 6 and 12 months. Mild toxicity and social discomfort were the mean reasons for dropout during maintenance (60%).
CONCLUSIONS
Severe toxicity caused BCG interruption in a limited amount of cases. Almost 60% of treatment interruptions was attributable to low grade toxicity, inadequately considered by the urologists. The personal difficulties related to the prolonged treatment and the limited patients' awareness of the therapeutic value of maintenance were other important reasons. A structured periodical counseling and a timely recognition and therapy of mild but persistent symptoms, might significantly ameliorate patients' acceptance of BCG maintenance
THE ROLE OF INTRAVESICAL GLYCOSAMINOGLYCANS IN TOXICITY INDUCED BY ADJUVANT INTRAVESICAL THERAPY: GENETIC LABORATORY EVIDENCE
Introduction and Objectives: The intravesical administration
of hyaluronic acid and chondroitin sulphate solution (HA-CS)
has been proven active in patients affected by interstitial
cystitis (1). The gene expression of fibronectin (FN) in bladder
washings has recently been correlated with local toxicity of
adjuvant intravesical therapy (2). The aim of the study was to
investigate the genetic evidence of the healing or protective
action that HA-CS could carry out also in patients suffering
from topical toxicity induced by intravesical adjuvant therapy
given for non-muscle invasive bladder cancer. Materials and
Methods: The study included 50 patients submitted to adjuvant
intravesical therapy with mitomycin, epirubicin or bacillus
Calmette–Guérin (BCG). Ten age-matched healthy patients
were enrolled as control group. Before, during and after
intravescical therapy, bladder washing samples were collected
to investigate the gene expression of FN. In 9 more patients
the samples were collected also immediately before and a
week after the instillation of HA-CS. Topical toxicity was
classified into 3 grades: 0-1, light (no medical therapy); 2,
moderate (medical therapy); 3, severe (instillation postponed).
Bladder washing samples were analyzed by isolation of
cellular RNA using a miRNeasy Mini Kit (Qiagen®). RT-PCR
was performed in order to analyze FN gene expression.
Changes in the FN content were calculated using the ΔΔCt
method after normalization with endogenous reference 18s
rRNA and calibrating Ct value for each RNA obtained for
triplicate reactions. Statistical analysis was performed to
correlate the FN gene expression to tumor characteristics,
treatment, topical toxicity and intravesical administration of
HA-CS. Results: FN median value before the adjuvant
treatment was 1.1-fold, with higher levels in patients with
multiple tumors (median FN=1.5; mean=3.9; p=0.0003).
Twenty patients (34%) showed grade 2-3 toxicity. Compared
to controls (FN=1), FN increased during therapy a median of
4-fold (range=0.2-45.2; mean=7.5) in presence of grade 2-3 toxicity, remaining stable in asymptomatic patients (median
FN=0.6; range=0.1-3.2), with a statistically significant
difference (p=0.0005). In 9 patients, one week after single
instillation of HA-CS, the median FN gene expression
decreased from 3.2 to 0.33 with concomitant symptomatic
relief. Discussion and Conclusion: Fibronectin is a
fundamental element for the repair of urothelial damage. FN
gene is probably activated by the need of fibronectin for
healing process and down-regulated by the integrity of bladder
urothelium. In our preliminary experience FN gene expression
in bladder washings resulted strictly related to local toxicity
induced by intravesical therapy. It increases after transurethral
resection (TUR) of multiple tumors due to the greater
urothelial damage. It increases also during intravesical therapy
reaching the highest levels in case of severe toxicity due to the
extensive urothelial damage. A single instillation of
intravesical hyaluronic acid and chondroitin sulphate solution
induces a rapid reduction of FN gene expression levels,
particularly when high levels are present. The FN gene downregulation
induced in patients with toxicity is due to
intravesical therapy and might represent an objective and
measurable indicator of the healing activity of intravesical
instillation of HA-CS.

CORRELATION BETWEEN FIBRONECTIN GENE EXPRESSION AND LOCAL TOXICITY INDUCED BY ADJUVANT INTRAVESICAL THERAPY
Discomfort and local
toxicity often cause interruption of intravesical adjuvant therapy for non
muscle invasive bladder cancer (NMIBC). A marker of urothelial damage
could be helpful for early detection and monitoring of topical toxicity
to ameliorate the tolerability of the intrravesical therapy. The aim of the
study is to investigate the correlation between the gene expression of
Fibronectin (FN) in bladder washings and local toxicity of adjuvant
intravesical therapy
