RESUMEN

<p><b>BACKGROUND</b>Overactive bladder (OAB) is a series of symptoms with high prevalence in elderly people. This study was conducted using the overactive bladder symptom score (OABSS) to evaluate the efficacy of solifenacin succinate for the treatment of OAB.</p><p><b>METHODS</b>This was a prospective, multicenter, single-arm, 12-week study that enrolled 241 OAB patients. The patients received 5-10 mg/day solifenacin. Changes in OABSS, symptoms from voiding diary, perception of bladder condition (PPBC) score, international prostate symptom score (IPSS) and quality of life (QOL) were evaluated at weeks 0, 4, and 12. The relationship between OABSS and PPBC score or parameters of voiding diary was also evaluated.</p><p><b>RESULTS</b>At baseline, the mean OABSS for all patients was 9.41 ± 2.40, and was reduced significantly at week 12 (-3.76 points; 61.21%, P < 0.0001). The OABSS subscore, PPBC score, IPSS, and QOL were also significantly reduced during the study (P < 0.0001). The overall incidence of adverse events was 19.91% (44 cases). The gastrointestinal system was the most commonly affected (11.31%). Around 5.88% of the cases had adverse events related to the genitourinary system. There was a strong correlation between OABSS and urinary symptoms that was recorded in the 3-day voiding dairy.</p><p><b>CONCLUSIONS</b>We showed that solifenacin was clinically effective for relieving OAB symptoms, considering the balance between efficacy, patients' well-being, and tolerability. OABSS integrates four OAB symptoms into a single score and can be a useful tool for research and clinical practice.</p>

RESUMEN

Objective To explore the safety and efficacy of small margin in nephron sparing surgery for early localized renal cell carcinoma (RCC). Methods A total of 325 cases of RCC with normal contralateral kidney and staged as Tla were retrospectivly studied.According to the margin size,125 cases were with surgical margin ≤ 5 mm (group ≤ 5 mm),102 cases with margin 6-9 mm (group 6-9 mm) and 98 cases with margin > 10 mm (group > 10 mm).The margin size and status was pathologically evaluated and clinical results including local recurrence,distant metastasis and overall survival rate were followed up and comparatively analyzed. Results None of the patients had positive surgical margins.The mean and median margin sizes were 2.2 and 2.0 mm for group ≤ 5 mm,6.7 and 6.0 mm for group 6-9 mm and 11.8 and 12.0 mm for group > 10 mm.The difference was statistically significant (P=0.025).The mean and median follow-up time for all the patients were 79 and 83 months (range 15-132 months),with 69 and 73 months (range,15-130 months) for group ≤ 5 mm,83 and 86 (range,17-132 months) for group 6-9mm and 82 and 82 (range 60-103 months) for group > 10 mm.Three patients in group ≤ 5 mm,5 in group 6-9 mm and 2 in group > 10 mm died of no-cancer related disease during follow-up.One patient in group ≤ 5 mm (0.74%) experienced ectopic recurrence in the same kidney and one in group 6-9 mm was detected local recurrence in situ (0.98%).No distant metastasis was detected in all the patients.The overall 5-year survival rate for patients in groups ≤ 5mm,6-9 mm and > 10 mm were 99.2%,99.0% and 98.0%,respectively.(Kaplan-Meier survival analysis,Log Rank,x2 =1.511,P=0.470). Conclusions Small margin in nephron sparing surgery is safe and effective in treating RCC with stage T1a,which provides excellent renal function preservation,favorable long-term progression-free survival rate,and is not associated with an increased risk of local recurrence.

RESUMEN

Eighty six patients with renal masses≤4.0 cm underwent ultrasound or CT-guided core needle biopsies.The clinical data including the initial biopsy technique,pathologic findings,and the clinical outcome were retrospectively reviewed. Biopsies were failed for diagnosis in 6 cases ( 7% ) because of necrosis or hemorrhage of the tissue specimens.Of 80 successful biopsies,52 cases (65%) were diagnosed as malignant tumor and 28 cases (35%) as benign. Five patients had biopsy complications (6%),including postoperative hypotension,hemouria and perirenal hematoma. Forty-seven patients underwent surgical extirpation ; the consistency rate of histopathological diagnosis between biopsy and surgical specimens was 100% in these patients.The results indicate that ultrasound or CT-guided core needle biopsy is an effective and safe procedure for diagnosis of renal small masses.

RESUMEN

Objective To evaluate the long-term therapeutic results and the safety of nephronsparing surgery(NSS) for the treatment of renal cell carcinoma. Methods Clinical data of 243 NSSfor renal cell carcinoma were retrospectively analysed. Of them, 159 were males and 84 were femaleswith average age of 58 years (range from 24 ?77 years). The average tumor size was 3. 4 cm (rangefrom 1.1 to 6. 7 cm). Three cases were solitary renal cell carcinoma, 11 were bilateral renal cell carcinoma; 237 cases were in stage T_(1a). and 6 cases were in stage T_(1b). No lymph node and distant metastasis, no renal vein cancer tumor embolus and inferior vena cava tumor embolus was found. Postoperative follow-up was carried out by ultrasound, CT and renal function. Cancer specific survival was estimated using Kaplan-Meier method and log-rank test. Results After a mean 31 months (1-147months) follow-up, long-term follow-up data were obtained in 232 cases because the other 11 did notlive in Dalian, 52 were treated with interferon. Four of the 232 patients treated with NSS had died:1died from lung cancer 16 months after lung cancer treatment, the other 3 died from cardiovascular diseases. The total survival rate and cancer specific survival rate were 98. 3% and 100. 0%, respectively.Local tumor recurrences were detected in 5 patients and tumor metastasis was detected in 1 patient.The recurrence rate was 2. 2%, and the metastasis rate was 0. 4%. The complications included temporary renal failure and urine leakage. The complication rate was 5. 6%. Conclusions NSS for renalcell carcinoma is a safe and feasible treatment option. It has the advantages of low local recurrence,good long-term survival rate and low complication rate. NSS can maximally reserve functional nephron, reduce the risk of chronic renal failure, preserve patient's quality of life and increase patient'ssatisfaction.

RESUMEN

Objective To study the relationship between X-linked inhibitor of apoptosis protein (XIAP) expression and transitional cell carcinoma(TCC) development. Methods Forty-three TCC tissues and 12 normal transitional epithelial tissues were applied to detect XIAP expression by semi-quantitative RT-PCR, immunohistochemistry and western blot. The data were statistically analyzed by using SPSS11.5 according to the 2 groups (TCC and normal transitional epithelial) as well as the dif-ferent subgroups (tumor stage, grade, single or multiple tumor, primary or recurrence tumor). Results XIAP expression in TCC tissues was higher than in normal transitional epithelial tissues(im-munohistochemistry: 22±5 and 16±2, Western blot:1.21±0. 15 and 0. 61±0.24, mRNA: 1.17± 0. 30 and 0. 75±0. 17, P<0. 05). In the bladder tumors group, XIAP expression in recurrence tumors was higher than in primary tumors(immunohistochemistry: 24±3 and 20±3, Western blot: 1.66±0.28 and 1.10±0. 23, mRNA: 1.44±0. 27 and 1.05±0. 23, P<0. 05). However, there were no significant differences according to the tumor stage and tumor grade as well as tumor multi-plicity or not. Conclusion XIAP expression might serve as a biomarker in TCC diagnosis and recur-rence prediction.

RESUMEN

We used the method of partial penectomy combined with penis lengthening to treat 2 cases of penile cancer. The penile lengths were lengthened by 3-4 cm. This method could retain the penis and sexual function to the maximum degree. And a few patients could avoid total penectomy and micturate on their feet. This operation is very simple and safe, with no complication.

RESUMEN

<p><b>OBJECTIVE</b>To investigate the incidence and associated factors of multicentricity in renal cell carcinoma (RCC) in Chinese patients.</p><p><b>METHODS</b>One hundred and two kidney samples from radical nephrectomy due to RCC were step sectioned at 3 mm intervals and examined. All tissue abnormalities were removed, stained and examined for multicentricity. Then, on each slice of the sample, both the parenchymal margin of 15 mm beyond the pseudocapsule and tissue around the renal sinus were continuously sectioned and examined for completeness of the pseudocapsule and vascular and lymph node invasion. The relationship between muliticentricity and other pathological parameters was evaluated.</p><p><b>RESULTS</b>The incidence of multicentricity was 15.7% (16/102); it was significantly lower in primary tumors < or = 4.0 cm than in tumors > 4.0 cm (4.9%, 2/41 vs 23.0%, 14/61; chi(2) = 6.055, P = 0.014). The incidence was 9.8% (8/82) in tumors without vascular invasion and 40.0% (8/20) in those with it (P = 0.003, Fisher's exact test). The incidence of multicentricity was 1.9% (1/53) in tumors with a complete pseudocapsule and 30.6% (15/49) in those without it (chi(2) = 15.885, P = 0.000). The grade, stage, subtypes and lymph node invasion of the primary tumor were not significantly associated with multicentricity. Multiple logistic regression analysis showed that pseudocapsular incompleteness and vascular invasion were two significant predictors of RCC multicentricity (P = 0.005 and 0.023).</p><p><b>CONCLUSIONS</b>The incidence of multicentricity of RCC in this group of patients was in accordance with published studies. Multifocality was significantly associated with tumor size, pseudocapsule completeness and vascular invasion. NSS should be limited to tumors less than 4.0 cm when the contralateral kidney is normal and careful long-term follow-up is necessary in tumors with positive vascular invasion and incomplete pseudocapsule.</p>

RESUMEN

Objective To investigate the clinical features of genitourinary invasion by malignant lymphoma.Methods Three cases of genitourinary invasion by malignant lymphoma were reported.Case 1,a 68-year-old man,complained of right flank malaise for 1 month.CT showed a soft tissue shadow of 4.0 cm?5.5 cm with homogeneous density at right renal hilus,and diffusely thickened right greater psoas muscle at the level from lower pole of the kidney to internal iliac muscle with low-density soft tissue shadow inside.Case 2,a 72-year-old man,presented with distended left leg for 2 weeks.CT indicated left seminal vesicle mass with soft tissue density of 2.5 cm in diameter,and a soft tissue mass of 6.5 cm?4.5 cm at the left iliac artery furcation.Case 3,a 48-year-old woman,complained of fever for 1 month.CT showed well-defined,solid masses of 8.0 cm?6.0 cm and 7.0 cm?6.5 cm,respectively,in diameter with inhomogeneous density at bilateral adrenal gland areas.The incidence,clinical features,prognosis and surgical treatment of this disease were summarized in combination with review of the literature.Results All 3 cases underwent operations.The primary foci originated from pelvic or retroperitoneal lymph nodes.The kidney,seminal vesicle and adrenal gland were involved in each of the 3 cases.The pathological types were all non-Hodgkin diffusive big B cell lymphoma.One case died 2 months after operation.The other 2 received CHOP chemotherapy after operation,and were followed for 4 months and 2 years,respectively.They were both alive with no recurrence at last time of the follow-up.Conclusions Genitourinary invasion by malignant lymphoma is an uncommon disease with atypical clinical presentations and poor prognosis.Surgical treatment has little effect,while radiotherapy and chemotherapy should be the first choice.Explorative surgery has positive significance for definite diagnosis.
