RESUMO
Carcinosarcoma is a rare malignant tumor with a biphasic morphology characterized by the presence of a malignant epithelial and mesenchymal component. It has been reported in many organs, including the genitourinary tract. We describe a case of a 47-year-old woman admitted to our hospital for history of recurrent urinary tract infection, dysuria and discharge of bloody fluid from the urethra at the end of urination. A tender palpable mass under the anterior vaginal wall was found and pathological examination showed a urethral carcinosarcoma. The histopathogenetic hypothesis and clinical management were considered in this report.

Many drugs can be used for adjuvant therapy of breast cancer, including anthracyclines, cyclophosphamide, 5-fluorouracil (5-fU) and, recently, taxanes (TXT) have shown promising results. 5-FU blocks thymidylate synthase (TS) which cross-links p53 mRNA, inhibiting its synthesis. TS overexpression is one of the main mechanisms involved in 5-FU drug resistance. Enough p53 mutations can confer resistance to chemotherapy using anthracyclines and 5-FU, while are associated with improved responses to TXT. The aim of this study was to examine the TS and p53 levels in tumor samples and to compare the efficacy of FEC (5-FU, epirubicin, cyclophosphamide) and TXT chemotherapy in a group of patients with differing TS and p53 status. We examined 84 breast tumor samples using immunohistochemistry. TS and p53 levels were inversely related, and TS and p53 positivity was significantly associated with the failure of FEC treatment and with a good response to TXT therapy (p <0.001). This confirms the predictive role of these two markers, which should be considered when choosing the appropriate adjuvant therapy for breast cancer.

To evaluate prostate cancer (PCa) detection and incidence of pathologically insignificant PCa (pIPCa) tumour using percent-free PSA (%f-PSA) in patients with total PSA ≤ 10 ng ml(-1). From February 2002 to October 2009, 14,453 patients (median 60.5 years) were enrolled in a case-finding protocol for the early diagnosis of PCa. Indications to biopsy were suspicious digital rectal examination; PSA >10 ng ml(-1); PSA ≤ 2.5 ng ml(-1), included between 2.6-4 and 4.1-10 ng ml(-1) with %f-PSA <15, <20 and <25%, respectively. A median of 18 and 26 cores in case of primary and repeated biopsy were determined; 2123 men underwent prostate biopsy, of whom 1589 (74.8%) had a PSA ≤ 10 ng ml(-1). A PCa was found in 777 (36.6%) and in 35 (23.3%) patients at primary and repeated biopsy: 459 and 26 men had PSA ≤ 10 ng ml(-1) and 419 and 26 patients underwent surgery, respectively, 244 (58.3%) and 18 (69.2%) had an organ-confined PCa with a pIPCa incidence equal to 1.4 and 7.7%, respectively. Cancer detection rate of 28.8% in patients with PSA ≤ 10 ng ml(-1) associated with a low incidence of pIPCa should induce to introduce %f-PSA in screening programmes to reduce the risk of overdiagnosis.

RESUMO
To evaluate prostate cancer (PCa) detection after repeated negative saturation biopsy, 75 patients, aged 53-78 years, underwent transurethral resection of prostate (TURP) because of persistent suspicion of cancer; median PSA was 11.8 ng ml(-1) and 58 men complained lower urinary tract symptoms (LUTS). In 12 (16%) and 3 (4%) men a T1a and T1b PCa was found with median PSA and Gleason score equal to 14.2 vs 23.6 ng ml(-1) and 5.6 vs 7 ng ml(-1). In case of persistent suspicion of PCa after repeated negative saturation biopsy, TURP may be proposed, aside from the coexistence of LUTS, to rule out a PCa, in younger patients with high PSA values (> or =20 ng ml(-1)).

OBJECTIVES: To evaluate the role of quantitative histologic findings in predicting nonorgan-confined (non-OC) prostate cancer (PCa) in patients undergoing saturation prostate biopsy (SPBx). METHODS: A total of 69 patients who had undergone SPBx underwent radical retropubic prostatectomy. Their prostate-specific antigen level was <10 ng/mL, and 49 and 20 patients had T1c and T2 PCa, respectively. The following biopsy variables from the quantitative histologic examination were evaluated as predictive of OC vs non-OC PCa: Gleason score (

Malignant tumours of the prostate other than carcinomas are rare. One such malignant tumours arising from the specialised stromal tissue of the prostate is stromal prostatic sarcoma (namely low-grade and high-grade). Herein, we report the clinico-pathological features of a high grade stromal sarcoma of the prostate occurring in a 65-year-old man who presented for urinary obstructive symptoms. The clinical picture suggested a benign prostatic hyperplasia, and surgery consisting in a transcapsular adenomectomy was performed. Following a pathological diagnosis of high grade prostatic stromal sarcoma, a radical cystoprostatectomy and bilateral pelvic node dissection was performed showing residual high grade stromal sarcoma of the prostate and incidental in situ urothelial carcinoma of the bladder. No further medical treatments were planned. One year after surgery the patient is well with no evidence of local disease or distant metastases.

Microscopic foci of prostatitis may induce prostate-specific antigen (PSA) increase. PSA reduction after antibiotics might identify those patients in whom biopsy can be avoided. Ninety-nine patients received ciprofloxacin for 3 weeks, of whom 59 showed PSA reduction. Histology detected small foci of prostatitis in 65% of cases. Carcinoma was found in 40 and 20.3% of patients with unchanged or decreased PSA, respectively (P=0.03). No cancer was detected if PSA decreased below 4 ng/ml or more than 70%. Biopsy can be postponed, with a low risk of missing a cancer, if PSA decreases more than 70% or below 4 ng/ml.

BACKGROUND: The development of oesophageal adenocarcinoma is generally closely associated with the presence of a specialised intestinal-type epithelium such as that found in Barrett's oesophagus (BO). A particular histological condition is when the distal oesophagus showing cardiac and/or fundic mucosa without intestinal metaplasia cannot be defined as 'Barrett's mucosa' [condition that we call 'columnar-lined oesophagus' (CLO)] and up till now, there has been no agreement in literature about the management of this condition. Aurora-A overexpression leads to centrosome amplification, chromosomal instability and aneuploidy in mammalian cells. PATIENTS AND METHODS: A prospective study was carried out on 28 consecutive patients who presented columnar mucosa above the gastro-oesophageal junction (GOJ) at endoscopy. As controls, two more biopsies were obtained, one on the normal-appearing squamous oesophagus above the GOJ, as far as possible from the columnar mucosa (controls A), and one taken 1 cm below the GOJ (controls B). The Aurora-A and p53 expression levels were analysed respectively by Quantitative Real Time PCR and immunohistochemistry. RESULTS: Twelve patients were affected by BO (43%) while the other 16 patients (57%) had a CLO. Nine of 28 (32%) cases were focally positive for p53 immunostaining. All the BO/CLO samples were positive for the Aurora-A transcript with regard to controls. Furthermore, 13 of 28 (46%) cases showed overexpression (above the median for the whole group). CONCLUSION: Due to the low number of cases, we are not at present able to state that statistically significant quantitative differences in Aurora-A messenger RNA expression exist between CLO and BO cases with and without dysplasia and p53-positive immunostaining. Further studies on a larger number of cases with a follow-up period are necessary in order to establish the risk of progression and the correct management of these subjects.

Breast cancer is a heterogeneous disease, so therapeutic predictive biological markers need to be identified. To date an accurate evaluation of predictive markers is mainly done at the primary site; however, the main goal of adjuvant therapy for breast cancer is the control of micrometastases. The aim of this study is to assess as therapeutic and/or prognostic marker, the proliferation status of primary tumors and involved nodes as measured by Ki67 and thymidylate synthase (TS) expression, in 30 breast cancer node positive patients. TS is the main target of 5-fluorouracil (5-FU) activity, and its overexpression is one of the mechanisms of 5-FU drug resistance; however, in some studies its absence is responsible for a worse response to 5-FU. Our results show that malignant cells of involved nodes were in a post mitotic phase of the cell cycle, and show a low proliferation index and TS expression, while the primary tumours and controls, were strongly positive. On these basis we can hypothesize that these cells could be less sensitive to 5-FU. Further studies are necessary to identify other mechanisms responsible for their metastasing capability and/or for their aggressiveness.

UNLABELLED: The aim of the study was to verify by Ki-67 immunostaining if any difference exists in the cell proliferating fraction between primary breast tumors (PTs) and matching positive axillary lymph nodes (ALNs). PATIENTS AND METHODS: Immunohistochemistry with the monoclonal antibody against Ki-67 was performed in 160 node-positive breast carcinomas and in their respective lymph node metastases. RESULTS: An increase of Ki-67 immunoreactive cells in ALN compared with that of PTs was observed in 84% of cases (ALN: mean 17%, PTs: mean 8%; p < 0.001), whereas 16% of the cases showed Ki-67 value two to six times lower in the ALNs than in the corresponding PTs (ALN: mean 3.2%, PTs mean 12.5%; p < 0.005). The decrease of Ki-67 positive cells in the ALN was independent from the histotype and the histological grade of the tumor. CONCLUSION: A different cell proliferation fraction between PTs and matching positive ALNs was demonstrated and underlined that the existence of a group of patients with decreased number of Ki-67 immunoreactive cells in lymph node metastases compared with that of the primary tumors could be taken into account in the choice of therapeutic strategy.

RESUMO
AIMS: To find a predictor of extraprostatic extension in clinically localized prostate cancer (PCa), pre-operative ultrasound-guided prostate needle biopsies and clinico-pathological data were reviewed. METHODS: One hundred and eighty-three consecutive patients who underwent radical retropubic prostatectomy for clinical T1-T2 PCa and serum PSA <10 ng/ml were reviewed. Pre-operative biopsy was performed according to an extended protocol and whole-mount prostatectomy specimens were processed. The following biopsy variables were categorized to this analysis: Gleason score (< or =6, >6), TPC (< or =20%; >20%), GPC (< or =50%; >50%), cancer-positive cores (< or =2; >2), cancer-positive cores in both lateral portions (yes; no), PCa (monolateral; bilateral). RESULTS: Only 60/183 specimens showed an organ-confined PCa; the remaining ones showed pT3a in 57 cases, pT3b in 11 and pT3 with positive surgical margins in 55. A locally advanced PCa was found in 60.2 and 76.8% of T1c and T2 clinical stage, respectively. The positive predictive value and negative predictive value of biopsy findings to predict a locally advanced PCa was 89.9 and 75%, respectively. All biopsy variables associations were statistically significant; however, among these variables (non-categorized), in multivariate logistic regression analysis, only GPC was significantly associated with pathologic stage (odds ratio estimate was 1.075, 95% CI: 1.053-1.098). CONCLUSIONS: Quantitative histology, especially GPC, seems to be helpful for pre-operative staging of PCa in patients with T1c-T2 clinical stage and PSA < 10 ng/ml.
