[The usefulness of Ki67 expression in the biopsy specimens, to predict the biochemical progresion of the prostate cancer after radical prostatectomy].

OBJECTIVE: To evaluate the usefulness of Ki67 expression in the biopsy specimens, to predict the biochemical progression of the prostate cancer after radical prostatectomy. MATERIAL AND METHODS: We analyse the Ki67 expression in the biopsy specimens of 103 patients treated with radical prostatectomy. The mean follow up is 3.4 years (1.3-8.8 years). We correlate the biochemical progression with traditional prognostic factors as the PSA (> 10/< or = 10), Gleason (> or = 7/< 7), pT classification (pT3/pTO-2) and immunohistochemical factor Ki67 (> 3%/< or = 3%). RESULTS: Of all 103 patients, in 71 (69%) biochemical progression was not detected and in 32 (31%) biochemical progression was detected. The mean of preoperative PSA is 10.07 ng/ml in the patients without progression and 20.90 ng/ml in the patients with biochemical progression (p=0.0001). The mean of Gleason score in 6.03 in the patients without progression and 6.75 in the patients with biochemical progression (p=0.0001). The percentage of Ki67 expression is 3.95% in the patients without progression and 5.05% in the patients with biochemical progression (p=0.030). The tumors pT0-2 progressed 12/67 (17.9%) and the tumors pT3 progressed 20/36 (55.6%) (p=0.0001). Multivariant regression analysis indicate that it does not exist a statistically significant relation between Ki67 (> 3%/< or = 3%) expression in the biopsy specimens and the biochemical progression of the prostate cancer after radical prostatectomy (p=0.204). CONCLUSIONS: The immunohistochemical factor Ki67 (> 3%/< or = 3%) in the biopsy specimens, is less effective than the classic factors, PSA (> 10/< or = 10), Gleason (> or = 7/< 7) and pT classification (pT3/pT0-2), to predict the biochemical progression of the prostate cancer after radical prostatectomy.

[Mucinous adenocarcinoma of the urachus].

OBJECTIVE: The Adenocarcinoma of the Urachus is very rare tumor, with an incidence of 1/5,000,000 inhabitants, represents less than 0.001 of all types of bladder cancer. CASE REPORT: A 51 year old man with a chronic history of suprapubic pain and hematuria. Physical examination and excretory urography were normal. The cystoscopy demonstrated a oedematosa area in cupola of bladder wall. The transuretral biopsy was moderately differentiated adenocarcinoma, with positive antibody to CK7 and CK20, the carcinoembryonic antigen was 6.6 ng/ml. Extended partial cystectomy was done, followed for chemotherapy and radiotherapy. CONCLUSIONS: The treatment of adenocarcinoma of the urachus with a combination of extended partial cystectomy, chemotherapy and radiation, is a effective treatment.

[Correlation of the anatomo-pathological staging of radical prostatectomy specimens with the amount of cancer in the preoperative sextant biopsy].

OBJECTIVE: We assess the value of the percent of cancer in needle cores of sextant biopsy for predicting the risk of extraprostatic extension at radical retropublic prostatectomy. MATERIAL AND METHODS: We reviewed prostate needle biopsy findings in 97 patients with prostate cancer T1c-T2, who subsequently underwent radical retropubic prostatectomy. In each needle biopsy were assessed, number of cores positive, percent of cores positive, percent cancer in all cores, Gleason score, intraepithelial neoplasia, perineural invasion and vascular invasion. Initial PSA and preoperative clinical stage were incorporated with biopsy results into a univariate and multivariate model to determine the parameters most predictive of pathological stage. RESULTS: Of the 97 patients, 72 (74%) had organ confined cancer and 25 (26%) had extraprostatic extension. The average of cores positive for organ confined cancer was 4.2 (median 4) vs. 6.9 (median 6) for extraprostatic extension (p = 0.001), the percent of cores positive for organ confined cancer was 34.9% (median 28) vs. 53.8% (median 46) for extraprostatic extension (p = 0.013). The average of cancer in all cores in organ confined cancer was 13.6% (median 6) vs. 30.5% (median 30) for extraprostatic extension (p = 0.002). The mean Gleason score in needle cores was 5.9 (median 6) in organ confined cancer vs. 6.6 (median 7) in extraprostatic extension (p = 0.007). The average of intraepithelial neoplasia in needle cores was 3 (4%) in organ confined cancer vs. 1 (4%) in extraprostatic extension (p = 0.972). The perineural invasion of needle cores was 6 (8.3%) in confined cancer vs. 4 (16%) in extraprostatic extension (p = 0.355). Univariate analysis demonstrated that the risk of extraprostatic extension is predicted by the number of cores positive (p = 0.003), the percent of cores positive (p = 0.006), the percent of cancer in all cores (p = 0.001), the Gleason score (p = 0.002), the clinical stage (p = 0.019) and initial PSA (p = 0.032). Extraprostatic extension is not predicted by the intraepithelial neoplasia (p = 0.971), vascular invasion and perineural invasion (p = 0.285). Multivariate analysis showed that the percent of cancer in all cores is the strongest predictor of extraprostatic extension (p = 0.035). With a percent of cancer less than 3% in the biopsy specimen, the risk of extraprostatic extension is 11.5%. CONCLUSIONS: The amount of cancer on preoperative needle sextant biopsy is the strongest predictor of prostate stage, but it is slightly practical at the moment of admitting or to reject a patient for radical prostatectomy.

[Value of a second transurethral resection in the assessment and treatment of patients with bladder tumor].

OBJECTIVE: To analyse the value of a second transurethral resection, repeated within 3 to 6 weeks after the initial resection, in the treatment and the classification of patients with bladder tumour. MATERIAL AND METHODS: We analyse the results of 72 repeated transurethral resection in 23 (32%) patients with T1 G1-2 bladder tumor, 9 (12.5%) with T1 G3 tumor, 31 (43%) with T2a G2-3 tumor and 9 (12.5%) with T2b G2-3 tumor. The evaluated patients are not associated with CIS. RESULTS: Of all 23 T1 G1-2 tumors, 13 (57%) had residual Ta T1 tumor and 1 (4%) T2 tumor. In this group, the second resection changed the treatment in 1 (4%) patient. Of all 9 T1 G3 tumors, 4 (44%) had residual T1 tumor and 1 (11%) T2 tumor. In this group the second resection changed the treatment in 1 (11%) patient. Of all 31 T2a G2-3 tumors, 5 (16%) had residual T1 tumor, 4 (13%) T2 tumor and 6 (19%) T3-T4 tumor. In this group, the second resection changed the treatment in 10 (32%) patient. Of all 9 T2b G2-3 tumors, 2 (22%) had residual T1 tumor, 1 (11%) T2 tumor and 2 (22%) T3-T4 tumor. In this group, the second resection changed the treatment in 3 (33%) patients. CONCLUSIONS: In T1 G1-2 and T1 G3 tumors, a second transurethral resection detect residual tumor in 36% of patients and change the treatment in 6% of patients. In T2a-b tumors, a second transurethral resection detect residual tumor in 50% of patients and change the treatment in 33% of patients.

[Metachronous tumors of the upper urinary tract following primary superficial tumors of the bladder].

OBJECTIVE: To evaluate the long term incidence of upper urinary tract tumours in patients with surface tumours of the bladder. MATERIAL AND METHODS: Analysis of 78 patients with primary tumour of the bladder pTa-pTl diagnosed between 1978 and 1988. These patients were followed for up to 10 to 21 years (mean follow-up 13.4 years) and were treated with transurethral resection and a variety of endovesical cytostatic agents. RESULTS: Of all 78 patients, 9 (11%) developed an upper urinary tract tumour over an average of 9 years (range 4-18); 2 in the first 5 years, 4 between 5 to 10 years, and 3 between 10 and 18 years. The likelihood of finding a tumour in the upper tract if all 20-year old patients were to be followed would be 25.6% (Kaplan-Meier's method). A high percentage of all upper urinary tract tumours are infiltrant, but the cause of death in 44% of these patients is progression of the tumour of the bladder. CONCLUSIONS: The percentage of tumours of the upper urinary tract that become metachronic following a tumour of the bladder, increases with the duration of the follow-up. A high percentage of these cases are already in high stages when diagnosed. It would be convenient to monitor the upper urinary tract with the same periodicity than the bladder in order to establish early diagnoses. These patients show a high mortality rate, in most cases secondary to progression of the tumour of the bladder.

[Abdominal-pelvic actinomycosis with urinary tract involvement, secondary to gynecologic infection caused by intrauterine device].

Abdomino-pelvic actinomycosis is a condition caused by Actinomyces israelii, a Gram-positive opportunistic bacteria that triggers and develops the infection only in previously injured tissues, and then slowly progresses and spreads until it extrinsically affects the urinary tract. Use of an intrauterine device is a known risk factor to suffer from this disease. Relative risk in IUD users is two- to four-fold higher compared to IUD non-users. Risk increased with prolonged IUD use. Treatment is by removal of the causative agent, surgical resection of necrotic tissues and administration of intravenous Penicillin G, 4 million units every 4 hours for 30 days, followed by Amoxicillin 500 mg every 8 hours for 12 months. This paper contributes two cases of abdomino-pelvic actinomycosis with urinary tract involvement in IUD users. Standard treatment was employed with good evolution.

[Fournier's gangrene: anatomo-clinical features in adults and children. Therapy update].

Fournier's gangrene is a skin infectious-necrotising process in the peri-neogenital area affecting males, usually in their sixties or seventies. Isolated flora from cultures of the necrotic lesion is commonly multi-microbial. In a majority of cases both aerobic and anaerobic micro-organisms are found in the cultures, Escherichia coli being the most commonly identified germ. Although considered in the past an idiopathic condition, in most patients today a genitourinary, anorectal or dermal triggering factor can be identified. There are a series of systemic host debilitating disorders such as diabetes mellitus, chronic alcohol abuse, and malignant neoplasia that are associated to this condition and may be considered risk factor to suffer this disease. Fournier's gangrene in children show specific bacteriological, pathogenic, clinical, therapeutic and prognostic features that distinguish it from that in adults. The most extensively accepted management for this condition includes therapy with broad-spectrum parenteral antibiotics and early and aggressive surgical debridement of the necrotic areas. Mortality continues to be high, ranging between 10-80% in the various series. Finally, a group of 7 patients with Fournier's gangrene is analyzed (1991-1998) aiming to establish a comparison between our results and those seen in recent series.

[Leiomyoma of the female urethra].

Leiomyoma of the female urethra is a benign mesenchymal tumour highly infrequent in the clinical practice. There is controversy as to its degree of oestrogen hormone dependency and its diagnosis is reached only after pathohistological study of the resection specimen. This type of tumour has excellent prognosis, with few tumoral relapses and no case of malignant transformation having been reported for the time being. Contribution of one case report of leiomyoma of the female urethra with typical clinical-epidemiological features but very uncommon from a topographic insight, as it was located in the anterior side of the distal urethra.

[Metastatic prostate adenocarcinoma in hernial sac. Contribution of one case].

Presentation of a case of stage D2 prostatic adenocarcinoma, diagnosed through a chance finding of micrometastasis in the pathohistological study of the hernial sac of a patient undergoing inguinal herniorrhaphy. Most usual sites for prostate cancer metastasis are lymph nodes, bones, lungs, liver, and brain. During our revision of unusual anatomical sites for prostatic carcinoma metastasis, we found references of metastasis on the uvea, larynx, orbit and maxillary sinus. The peritoneal cavity was not found to be a common site for metastatic implants. It was also found that such peritoneal spread was usually diagnosed after a postmortem examination.

[Value of non-contrast helical computerized tomography in nephrotic colic assessment].

OBJECTIVE: To compare non-contrast helicoid CAT to urological ultrasound in order to determine the sensitivity of both in the etiological diagnosis of nephritic colic. MATERIAL AND METHODS: Retrospective study conducted on a total of 86 patients seen in our ER service over a 12-month period with a diagnosis of nephritic colic. All patients with suspicious diagnosis of nephritic colic underwent X-ray examination, with either non-contrast helicoid CAR or urological ultrasound, or with a combination of both imaging techniques. Radiologic diagnosis of nephritic colic was made by direct visualization of the obstructive cause or by the presence of indirect radiological signs of upper urinary tract obstruction. RESULTS: Of 86 patients studied, in 84 (97.67%) a urinary stone was the cause for obstruction. Overall sensitivity of helicoid CAT to diagnose colic etiology was 94.73%, whereas ultrasound sensitivity was only 53.42%, displaying a particularly low sensitivity when the obstruction was located at the mid third level of the ureter. CONCLUSIONS: Non-contrast helicoid CAT shows superior sensitivity as a radiologic technique than ultrasound to identify the cause of a nephritic colic in any segment of the upper urinary tract.

[A massive hernia of the bladder into the scrotum. A report of a case].

The hernia of the bladder in the scrotum is a highly uncommon observation. From the clinical standpoint the usual manifestation is a two-stroke voiding. The recommended urological examinations to reach a diagnosis are ultrasound, endovenous urography, retrograde urethrocystography and cystoscopy. Management includes the de-obstruction of the lower urinary tract, if present, resection of associated peritoneum, resection or reduction of the vesical hernia and repairment of inguinal path. The case contributed corresponds to a vesical hernia in a 72-year-old patient, with no obstructive cause, that was treated surgically by resection of the herniated bladder, with good morphological and functional results.

[Superficial cancer of the bladder: which controls should follow and for how long the free of tumor patients?].

OBJECTIVES: To answer the following question: what monitoring and for how long should be maintained in patients with Ta-T1 vesical neoplasia and no tumoral relapse? MATERIAL AND METHOD: Analysis of relapse probabilities in 123 patients with Ta-T1G1G2G3 primary tumours who had not relapsed for at least three years of follow up after transurethral resection. All patients were treated between January 1976 and December 1986; they all have follow-up potential of over 10 years. Mean follow-up 8.1 years, minimum 4 years, maximum 18 years. RESULTS: Probabilities of relapse at 3 to 5 years, 6 to 10 years, 11 to 18 years are 18%%, 24% and 13%, respectively. Relapses were superficial in 38 cases (90%), infiltrant in 4 (10%) G1 in 21 (50%), G2 in 12 (29%), G3 in 9 (9%), single in 33 (79%), multiple in 9 (21%), under 2 cm in 35 (83%), over 2 cm in 7 (17%). CONCLUSIONS: Epidemiologically, individuals with a background of surface vesical tumour have a much higher risk of relapse than the Spanish normal population and therefore they should be monitored for life. Relapses are usually superficial, low grade, single and small in size. Cystoscopy is the monitoring technique offering more possibilities for detection.

[Prevention of superficial bladder cancer with mitomycin C or interferon: final results of a prospective study].

OBJECTIVES: Herein we present the final results of a prospective randomized study comparing two prophylactic treatment modalities for superficial bladder tumors: chemotherapy with mitomycin C and immunotherapy with interferon. METHODS: The study comprised 65 patients. Mitomycin C was utilized in 34 and interferon in 31 patients. RESULTS: The mitomycin C-treated patients had 41% recurrence, 1.7 recurrence/100 patients-month, 17 months mean time to recurrence and 8.8% tumor progression. The patients receiving interferon had 45% recurrence, 2.4 recurrence/100 patients-month, 12 months mean time to recurrence and 22.2% tumor progression rate. No significant differences were observed between the two groups of patients. Treatment was well-tolerated by both groups and the cost:efficacy ratio was higher for the interferon-treated patients. CONCLUSIONS: Immunoprophylaxis with interferon is as effective, but costs more than chemoprophylaxis with mitomycin C. Both agents have a moderate effect relative to control of recurrence, time to recurrence and tumor progression.

[Bladder leiomyoma].

OBJECTIVE: Mesenchymal benign tumours of the urinary bladder are rare and account for 1%-5% of all bladder tumours. The leiomyoma is the most common and constitute 46.6% of this group. 25 cases have been described in the national literature. We report an additional case of leiomyoma of the bladder. CASE REPORT: A 53 year-old man with a chronic history of urinary frequency and microscopic hematuria. Physical examination was normal. An excretory urography demonstrated a filling defect in the right bladder wall. The cystoscopy confirmed the tumour, covered with normal bladder mucosa. The echography showed a solid tumour. A computerised tomography scan and magnetic resonance showed a sessile lesion in the right bladder wall with low-intermediate intensity signal and with normal signal of muscle, mucosa and perivesical fat. The clinical diagnosis was leiomyoma of the bladder. Partial cystectomy was done and the histological diagnosis confirmed the clinical diagnosis. CONCLUSIONS: The leiomyoma of the bladder is a rare tumour however it should be considered in the differential diagnosis before surgical treatment.

[Prostate cancer recurrence after radical prostatectomy and salvage radiotherapy].

OBJECTIVE: To evaluate the efficacy of the radiotherapy to prostatic bed in patients with biochemical recurrence for prostate cancer after radical prostatectomy. MATERIAL AND METHODS: We analyse the results of 292 patients underwent radical prostatectomy for localized prostate cancer T1-T2 between January 1992 and June 2003, with an average folow-up of 36 months (range 6 months to 12 years). We detect biochemical recurrence (PSA >0.20 ng/ml) in 75 (26%) patients. Of 75 patients with biochemical recurrence, 9 (12%) was diagnosed of local recurrence by the following criteria: a) The first PSA obtained 6 weeks after radical prostatectomy <0.20 ng/ml. b) The time to biochemical recurrence >6 months. c) The prostate specific antigen doubling time >6 months. d) The prostate specific antigen velocity after radical prostatectomy <0.75 ng/ml/year. e) The prostate specific antigen level after radical prostatectomy <2.5 ng/ml. The 9 patients diagnosed of local recurrence received an average dose of 56.42 Gy in the prostate bed. RESULTS: Of all 9 patients with local recurrence, 7 (77.7%) has complete response with an average time of follow-up of 25 months (6-30 months). The time between the radiotherapy and the response, in patients with complete response, was lower than 3 months. Were not observed significant adverse effects associated to radiotherapy. CONCLUSIONS: The salvage radiotherapy may be beneficial in select patients with local recurrence. The characteristics of prostate specific antigen elevation are useful in distinguishing men with local recurrence from those with distant metastases.
