Background: Neuroendocrine tumours (NET) are extremely rare and aggressive. Although they commonly affect intestine, many organs may be involved such as pancreas, lung or urinary tract. Bladder is rarely involved. Actually, two main forms of bladder NET have been described: small-cell and large-cell. The first one is considered highly agressive since it shows poor oncologic outcomes being mainly diagnosed at advanced stage: the second one is extremely rare and equally aggressive. Case report: A 78-years-old Caucasian male presented to our facility for lower urinary tract symptoms and gross hematuria recently occurred. He was a strong smoker since many years. No familiarity for urothelial cancer was referred nor previous episodes of hematuria until that time. Citology was negative; outpatient ultrasound of the bladder revealed a 3 cm bladder thickening highly suspicious for bladder cancer; patient underwent TC scan that confirmed the bladder lesion. A transurethral resection of the bladder (TURB) was performed. After 3 months total body TC showed multiple visceral metastases also involving brain and lymph nodes. Best supportive care was offered but the patient died 6 months later. Results: Pathology revealed a mixed bladder tumor: 30% of the specimen resulted as an high-grade urothelial cancer (G3) and 70% as small-cell neuroendocrine variant.Microscopic muscle involvement was excluded.Conclusions: Neuroendocrine tumors are uncommon entities which origin from cells of neuro-endocrine system and may potentially involve all human tissues. Neuroendocrine smallcell carcinoma of the bladder is a non-urothelial histotype: it is highly aggressive and diagnosed mainly at advanced stages. Whenever considering the high risk of metastatic spread and the poor prognosis, a multimodal approach is highly suggested. TURB alone is uneffective in disease control due to its aggressive nature. Unless metastatic, radical cystectomy and adjuvant chemotherapy represent the gold standard.
Chondrosarcoma is the second most common malignant tumor of the bone with an incidence of 1 in 200.000 per year. Axial skeleton is frequently involved showing poorer oncological outcomes than appendicular one: human pelvis is a site predilection. It is rarely associated to urinary obstruction but according to its localization, it can be frequently linked to compression of pelvic organs as bladder, prostate or bowel. We describe the case of a 52 years old caucasian male with history of advanced pelvic chondrosarcoma and severe hydronephrosis due to total bladder dislocation.
Purpose Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. Methods The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). ResultsThe two cohorts did not differ in terms of age and prostate-specific antigen (PSA) levels at biopsy. Patients enrolled in the Pros-IT-CNR project more frequently were submitted to RA (58.8% vs 27.6%, p < 0.001) and NS prostatectomy (58.4% vs. 52.9%, p = 0.04), but received LND less frequently (47.7% vs. 76.7%, p < 0.001), as compared to the MIRROR-SIU/ LUNA patients. At multivariate logistic models, Lower Gleason Scores (GS) and PSA levels were significantly associated with RA prostatectomy in both cohorts. As for the MIRROR-SIU/LUNA data, clinical T-stage was a predictor for NS (OR = 0.07 for T3, T4) and LND (OR = 2.41 for T2) procedures. As for Pros-IT CNR data, GS ≥ (4 + 3) and positive cancer cores ≥ 50% were decisive factors both for NS (OR 0.29 and 0.30) and LND (OR 7.53 and 2.31) strategies. Conclusions PCa management has changed over the last decade in Italian centers: RA and NS procedures without LND have become the methods of choice to treat newly medium-high risk diagnosed PCa.
— We investigated the accuracy of frozen sections in the detection of pelvic lymph node metastases in prostatic carcinoma. A group of 77 patients with clinical stage B or C prostatic cancer underwent staging pelvic lymphadenectomy followed by radical prostatectomy in 71 cases. Frozen section examination was performed in 46 cases because of the presence of suspicious lymph nodes. The accuracy of frozen section was 95.5% with 5.4% false negative results. Out of 24 patients with lymph node metastases confirmed by paraffin sections, 20 had frozen sections: 9 positive for cancer, 2 false negatives and 9 true negatives. Of the 31 patients from whom frozen sections were not obtained, 4 were found to have lymph node metastases on paraffin sections. In these 4 cases and in the presence of true negative frozen sections, nodal disease was minimal in 75% of patients. The results suggest that frozen sections are a useful tool to detect lymph node metastases. The accuracy depends on the experience of the histopathologist and the volume of the metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
