Prognostic value of static cytometry in transitional cell carcinoma of the bladder: recurrence rate and survival in a group of patients at 10 years follow-up.

Many studies have indicated that nuclear DNA content evaluation can be used to predict biological behavior of transitional cell carcinoma (TCC) of the bladder. Some authors also indicated that static cytometry is more useful in DNA content analysis than flow cytometry. The aim of the present study was to evaluate the prognostic significance of DNA ploidy in TCC of the bladder, performed by using static cytometry with an image analyzer, and monitoring patients at 10 years follow-up. Thirty-one consecutive patients underwent transurethral or open surgery for bladder tumors, and neoplastic tissue samples taken from each patient were imprinted on glass slides and sent for histopathological and DNA content evaluation. DNA ploidy evaluation was performed using a CAS 200 image analyzer. Nuclear DNA content evaluation was compared to patient follow-up on recurrence, progression or survival performed 10 years after surgery. Pathological evaluation demonstrated the presence of superficial TCC in 23 patients, while 8 had an invasive bladder tumor. Twenty-nine tumor samples were adequate for DNA content measurement, with 13 showing diploid DNA content and 16 with aneuploid DNA content. At 10 years follow-up, all patients with aneuploid DNA content demonstrated a lower survival time (p=0.049) and higher recurrence rate (p=0.0346). A log-rank test demonstrated that stage, grade and nuclear DNA content are the most useful prognostic parameters for predicting the biological behavior of TCC of the bladder. These results confirm that static cytometry is a good and reliable method to evaluate DNA tumor content and considered a useful prognostic parameter for predicting recurrence rate, disease progression or survival in patients affected by bladder tumors.

Qualitative and quantitative analysis of angiogenetic factors in transitional cell bladder carcinoma: relationship with clinical course at 10 years follow-up.

Many authors have shown that tumor hypoxia exerts its own influence on malignant progression by inducing angiogenetic factors and new blood vessels inside and around the tumor. This event usually suggests a poor prognosis and/or aggressive tumor behavior. The objective of the present study is to compare molecular analysis of angiogenetic factors with microvessel density (MVD) in bladder carcinoma. Twenty-nine consecutive patients underwent transurethral or open surgery for bladder tumors. Neoplastic tissue samples, normal-appearing bladder mucosa and blood samples were taken from each patient. All the tissues underwent mRNA extraction and Northern blot analysis, marked with specific probes for inducible nitric oxide sinthase (iNOS), cyclo-oxygenase-2 (cox-2), vascular endothelial growth factor (VEGF) and were evaluated by gel-electrophoresis. Microvessel density, a quantitative analysis for neoangiogenesis, was also evaluated by using CD31 immunohistochemical assay and compared with both molecular analysis and patient follow-up. Two follow-up for recurrence and/or progression were performed at 74 months and 10 years from surgery respectively. Pathological evaluation demonstrated the presence of superficial transitional cell carcinoma (sTCC) in 15 patients, while 14 had an invasive bladder tumor (iBT). At both 74 months and 10 years follow-up, all patients with lower MVD had a shorter survival time. No significant results were obtained by comparing disease progression or survival rate with VEGF, iNOS and COX-2 levels. A proportional increase of VEGF expression and MVD compared with poor prognosis was the expected outcome of our study. These results were disregarded at both the 1st and the 2nd follow-up. A strong association between MVD>20 and survival rate was noted both in sTCC (p=0.024) and iBT (p>0.001) patients. These results confirm that MVD could be considered a good prognostic factor. The angiogenetic cytokines overexpression found in control tissue samples of sTCC could have clinical significance, either as a macroscopically unidentified diffuse carcinogenetic process or the presence of a systemic immune-response against tumor cells.

Genitourinary cancer: psychological assessment and gender differences.

INTRODUCTION: The study of the psychological impact in patients diagnosed with cancer is an important topic. Cancer diagnosis can induce feelings of anxiety, depression, fear of recurrence and produce treatment side effects. Men and women tend to differ in their way of dealing with emotional distress and physical illness. The aim of this study is to investigate and evaluate the prevalence and detection of psychological disease in patients with genitourinary tumors and outline the eventual gender differences. MATERIALS AND METHODS: State-Trait Anxiety Inventory, Self-Rating Depression Scale and Illness Behavior Questionnaire were administered to 60 patients with genitourinary neoplasm. RESULTS: Most patients show symptoms of depression and anxiety during the hospitalization. We have observed a significant gender differences in the psycho-emotional assessment. CONCLUSION: Our study confirms the importance to make available for the patients a proper and continuous support in pre- and postsurgery period to prevent the generation of psychological disorders.

Clinical characterization of the prostatitis patient in Italy: a prospective urology outpatient study.

A prospective multi-center Italian urology outpatient survey, undertaken to determine the prevalence of prostatitis in Italy, provided an ideal opportunity to identify and characterize the typical prostatitis patient presenting to Italian urologists. A total of 70 urologists, representing a cross section of urologic centers in Italy, counted and recorded the overall total male patients reported in the clinic and the overall total patients diagnosed with prostatitis over a 5 week period in late 2001. Data on demographics, previous diagnoses, symptoms (frequency and severity), quality of life, physical examination and laboratory data were prospectively collected. A total of 1,148 patients were identified with prostatitis (12.8%). Of these, 1,074 patients had complete data and could be included in this characterization analysis. The mean age of the prostatitis patients was 47.1 years (range 16-83); two thirds had experienced their first symptom within the last year. A family history of prostatitis was reported by 20.4%. The most common urinary diseases were benign prostatic hyperplasia (17.4%), recurrent urinary tract infection (11.2%) and urinary calculogenesis (11.1%), while the most common concurrent diseases were diabetes (7.2%) and depression (6.8%). The most frequently reported and most severe symptoms at the time of evaluation were irritative voiding symptoms, perineal and suprapubic pain and discomfort. Over three quarters of the patients were dissatisfied with their quality of life. Bacteria were cultured in 15.6%, 17.7% and 14.0% of expressed prostatic secretions, urine specimens after prostatic massage and semen specimens, respectively. Prostatitis is a common outpatient diagnosis, comprising over 10% of male outpatient visits to urologists in Italy. This comprehensive characterization of the typical prostatitis patient diagnosed in routine urological outpatient practice can be employed to generate hypothesis-driven studies in diagnosis and treatment.

Early diagnosis and monitoring of superficial transitional cell carcinoma by microsatellite analysis on urine sediment.

It has recently been shown that allelic abnormalities, detected by microsatellite analysis of the DNA extracted from urine sediment, can be successfully used for the detection of transitional cell carcinoma (TCC) of the bladder. The diagnostic accuracy of urinary cytology, urinary bladder cancer (UBC) marker, bladder tumor antigen (BTA) and microsatellite sequence alterations was compared in 42 patients who were recruited for the study. Of them, 30 had been diagnosed with TCC at cystoscopy plus biopsy (group A). Seven patients without any apparent lesions after trans-urethral resection (TUR) and 6 subsequent weeks of endovesical administration of bacillus Calmette-Guerin (BCG), had irritative symptoms. None of them had positive cytology or TCC bladder mucosa biopsies (group B). In the control group were 5 other subjects who were affected by benign prostatic hypertrophy and candidates for prostatectomy (group C). Urine and blood samples were obtained from all of the patients before surgery. Tumor tissue and normal mucosa samples were taken from groups A and C during surgery. Different urinary sediment analyses were performed by using both nuclear medicine and molecular tests. UBC and BTA-t analyses were carried out using monoclonal antibody tests while microsatellite analyses were performed using extracted DNA and electrophoresis of polymerase chain reaction (PCR) products on 13 different primers. Urinary cytological examinations were carried out using the Autocyte Preparation System(R). Urinary cytology confirmed the presence of TCC in 13.3% of patients. The BTA-t marker allowed the identification of 73.3% of cancers with 50% specificity; the UBC marker identified 63.3% of the cases with 41.6% specificity. Microsatellite analysis permitted the identification of 83.3% of the tumors with 100% specificity. DNA analysis demonstrated high sensitivity in patients affected by superficial (81.4%) or G1 (80%) tumors, even when cytological studies demonstrated little or no sensitivity. Microsatellite analysis is a highly-sensitive and specific marker for TCC diagnosis and its monitoring, especially in patients with low-stage and low-grade tumors. Other testing procedures failed to increase urinary cytological diagnostic significance.

Twenty-years experience on genitourinary tuberculosis.

OBJECTIVE: We reviewed our surgical experience on genitourinary tuberculosis in the past 20 years in order to evaluate if any change in the incidence and management of this disease has occurred. PATIENTS AND METHODS: From 1980 to 1999, at our Institution, 102 patients underwent surgery for genitourinary tuberculosis. We recorded the data and the surgical procedure of these subjects and compared patients treated in period 1980-1989 to those submitted to surgery in the period 1990-1999. RESULTS: The overall incidence of surgical management of genitourinary tuberculosis in the past 20 years was 0.50% (102 cases on a total of 20,299 urological surgical procedures). In the decade 1980-1989 the incidence was 0.67% (70 cases out of 10,428 patients) and in the decade 1990-1999 it was 0.32% (32 cases out of 9,871 patients). Nephrectomy was the most prevalent surgical procedure performed in both decades. CONCLUSIONS: Despite the availability of effective antimycobacteric drugs, surgery continues to play a role in the management of genitourinary tuberculosis. This disease is very slow to progress with minimal and subtle symptoms, often resulting in irreversible damage of the organs involved by the time a diagnosis is established.

Ureteral endometriosis: an unusual case of a pelvic mass arising in the ureter and involving the rectum and uterine cervix.

The case of a 41-year-old woman with a pelvic mass arising in the left ureter is reported. The diagnosis of endometriosis was made on transperineal biopsy exclusively. After unsuccessful treatment with LH-RH analogues, the patient underwent ureteral resection and ureteroneocystostomy. At six months' follow-up, she is asymptomatic with no evidence of hydronephrosis.

Rhabdomyosarcoma of the spermatic cord. A case report with review of the literature.

Rhabdomyosarcoma is a rare malignant tumor that may occur in the spermatic cord in childhood. So far, 62 cases have been reported in the English literature. We describe a case of embryonal rhabdomyosarcoma of the spermatic cord in a 15-year-old boy, detailing clinical history, light microscopy, immunohistochemistry and treatment. In order to unquestionably demonstrate the myogenic differentiation of the neoplasm, it was decided to use a monoclonal antibody against MyoD1. The nuclear positivity of this phosphoprotein in the tumor cells confirmed the diagnosis of embryonal rhabdomyosarcoma. Consequently, the patient was treated with right radical orchiectomy and retroperitoneal lymph node dissection (RPLND). The latter is usually required because of the high incidence (more than 50% of cases) of positive retroperitoneal nodes, whereas subsequent adjuvant therapy is occasionally necessary. In the present case, we decided for a careful follow-up on the basis of the small size of the tumor and the absence of metastasis at diagnosis. The patient is alive and free of disease 12 months after surgery.

Non-functioning adrenal cortical carcinoma presenting with metastasis to the tongue.

We report a case of non-functioning adrenal cortical carcinoma (ACC) presenting with metastatic disease to the tongue, which is an extremely uncommon onset for this neoplasm. Histologically, the lesion had the appearance of an anaplastic neoplasm, and a panel of immunohistochemical markers including vimentin, MART-1, S100 protein, HMB-45, smooth muscle actin, common muscle actin, desmin, CD31, CD34, CD68, EMA and cytokeratins, was helpful in excluding melanoma, as well as other mesenchymal and epithelial neoplasms.

Molecular urinary sediment analysis in patients with transitional cell bladder carcinoma.

BACKGROUND: Nowadays urinary cytology methods in early diagnosis of superficial bladder transitional carcinoma (TCC) allow the identification of about 35-50% of tumors. Cytoscopy and biopsy are reliable but invasive. It has been recently shown that allelic abnormalities detected by microsatellite analysis of DNA extracted from urine sediment can be successfully used in TCC. We performed a comparative study between urinary cytology and microsatellite sequence alterations in patients affected by TCC. MATERIALS AND METHODS: Fifty-eight patients were recruited for the study. Of these, 45 had cystoscopic diagnosis of TCC, while 7 were without apparent lesions after TUR but presented urinary irritative symptoms after BCG endocavitary administration, and 6 who underwent open surgery for benign prostatic hypertrophy represented the control groups. DNA extraction and PCR analysis were performed by using 13 different primers, while urinary cytology was performed by using an Autocyte Preparation System. RESULTS: Urinary cytology confirmed the presence of TCC in 22% of patients while in 15.5% of them a displastic/inflammatory status was found. Microsatellite analysis allowed the identification of 82% of tumors with a 100% specificity. A high sensitivity was obtained in patients affected by superficial (79%) or G1(80%) tumors. CONCLUSION: Microsatellite analysis represents a highly sensitive and specific marker in TCC diagnosis and monitoring.

Leiomyoma of the corona glans penis.

A 42-year-old man presented with an 8-mm elliptical indolent solid mass on the superior surface of the corona glandis at our institution 3 months after its appearance. The lesion was excised by using a wedge resection performed by a cool blade knife. The subsequent pathologic evaluation defined the lesion as a leiomyoma. Immunohistochemical analysis using the streptavidin-biotin peroxidase technique and immunoreactivity for cytokeratin, S100 protein, and the proliferative marker MIB1 was performed, confirming the pathologic diagnosis. Early local excision of these tumors is indicated because of the trend toward their dimensions increasing quickly, with subsequent difficulties for cosmetic glandis reconstruction.

Hypospadias: incidence and effects on psychosexual development as evaluated with the Minnesota Multiphasic Personality Inventory test in a sample of 11,649 young Italian men.

PURPOSE: We evaluated the incidence of hypospadias and its effects on psychosexual development in a sample of 11,649 young Italian males. Over the last 30 years only about 30 major publications have addressed these issues and the results of many studies have been contrasting. Some defects in methodology, such as low response rates, heterogeneity of age ranges and the choice of controls, have been the main limitations. Our study was designed to take these problems into account. MATERIALS AND METHODS: Forty-two hypospadic subjects and a random sample of 500 nonaffected males selected from the large sample of 11,649 young men (>90% of the 18-year-old males living in the Italian region of Tuscany) were screened by the Minnesota Multiphasic Personality Inventory (MMPI) test, psychological interview and clinical evaluation. RESULTS: The incidence of hypospadias in this representative group of Italian men is 3.6/1,000. No difference was noted in the percentage with altered MMPI compared with the control group. The age at surgical corrections and the number of operations are not related to an abnormal global psychological adjustment. Severity of disease influences a more negative genital appraisal and the number of operations is correlated only with more difficulty in initiating contact with the opposite sex. CONCLUSIONS: Surgery for hypospadias has to be strongly pursued in as many cases as possible. In addition, we strongly recommend following up all hypospadics, independently of the severity of their genital malformations, through adolescence to early adulthood, to ensure early detection of subjects with impaired psychological profiles.
