Small Cell Carcinoma Articles

We evaluated epidemiologic trends and survival for bladder cancer histologic subtypes in California patients by comparing urothelial carcinoma of the bladder (UCB) and non-urothelial subtypes including squamous cell carcinoma (SCC), adenocarcinoma (ADC), and small-cell carcinoma (SmCC).

High-grade neuroendocrine carcinomas (HGNECs) of the urinary bladder encompass small cell (SCNEC) and large cell neuroendocrine carcinomas (LCNEC). Currently, recommended initial management is with systemic chemotherapy, followed by consolidative therapy with either radical cystectomy or radiotherapy in patients with localized disease.

Small cell carcinoma of the bladder (SCCB) is a kind of rare and highly aggressive tumor that is present in an advanced stage and has a propensity for early metastasis. The main presenting symptom of SCCB is hematuria.

Neuroendocrine prostate cancer (NEPC) is an aggressive variant of prostate cancer that may arise de novo or in patients previously treated with hormonal therapies for prostate adenocarcinoma as a mechanism of resistance.

Neoadjuvant chemotherapy (neoCTX) has been recommended as the optimal strategy in surgically resectable neuroendocrine carcinoma (NEC) of the urinary tract (NEC-URO).

To determine the systemic therapy regimen and timing, which are most active against NEC-URO.

Small cell bladder carcinoma (SCBC) is a rare, divergent form of urothelial carcinoma (UC). We aimed to determine whether pure (n=16) and mixed (SCBC and UC; n=30) tumors differed in pathology, gene expression characteristics, genetic alterations, and clinical outcomes.

The lineage relationship between prostate adenocarcinoma and small cell carcinoma was studied by using the LuCaP family of xenografts established from primary neoplasm to metastasis. Expression of four stem cell transcription factor (TF) genes, LIN28A, NANOG, POU5F1, SOX2, were analyzed in the LuCaP lines.

To determine the accurate age-adjusted incidence of prostate small cell carcinoma (SCC), update the clinical and pathological characteristics, as well as survival data of prostate SCC from Surveillance, Epidemiology, and End Results (SEER) datasets.

Small cell carcinomas (SMC) of the lung are now molecularly classified based on the expression of transcriptional regulators (NEUROD1, ASCL1, POU2F3, YAP1) and DLL3, which has emerged as an investigational therapeutic target.

Standard therapy for metastatic small cell carcinoma of the prostate (SCCP) remains undefined. We have effectively treated relapsed SCCP with amrubicin. A 72-year-old patient, diagnosed with T4N1M0 prostate cancer, started hormonal therapy in May 2012, elsewhere, and his prostate-specific antigen levels remained low.

Confirmation of genitourinary high-grade neuroendocrine carcinomas (GU-HGNECs) often requires immunohistochemical staining. Here we evaluated a novel neuroendocrine marker, insulinoma-associated protein 1 (INSM1), in GU-HGNECs with comparison to chromogranin, synaptophysin and CD56.

Small cell bladder carcinoma (SCBC) represents a rare histologic variant with a poor prognosis and for which no routine biomarkers exist. Limited reports of genomic sequencing in SCBC have demonstrated a high prevalence of TP53 and RB1 gene mutations, though the prognostic value of these and other gene variants in SCBC remains undefined.

Small cell carcinomas (SCC) make up only 1% of malignancies of the prostate. Reports of several case series have described outcomes of surgery and chemotherapy for SCC of the prostate, but few reports address radiotherapy.

Small cell carcinoma of the urinary bladder is a rare subtype (incidence of 1-9/1,000,000), characterized by an aggressive behavior with early metastasis and poor prognosis. Chemotherapy, radiation, and surgery are the usual treatment options, but to date, no accepted standard treatment exists.

Neuroendocrine neoplasms of the prostate represent a multifarious group of tumors that exist both in pure forms and associated with prostatic adenocarcinoma. Morphologically, neuroendocrine cells in prostate neoplasms can range from being indistinguishable from surrounding prostate adenocarcinoma cells to having high-grade neuroendocrine appearances similar to neuroendocrine malignancies of other organs.

Neuroendocrine neoplasms of the urinary bladder are a rare type of tumor that account for a small percentage of urinary bladder neoplasms. These tumors of the urinary bladder range from well-differentiated neuroendocrine neoplasms (carcinoids) to the more aggressive subtypes such as small cell carcinoma.

Non-transitional cell carcinomas (non-TCC) of the upper urinary tract as squamous cell carcinoma (SCC), adenocarcinoma, and small cell carcinoma (SmCC) are rare with few case reports in the literature.

Small cell carcinoma of the bladder is extremely rare, accounting for <1% of all malignant tumours in the urinary tract. Thus, no standard therapy modality for this malignancy has been established.

Many patients with muscle-invasive bladder cancer (BC) are either ineligible for or do not benefit from cisplatin-based chemotherapy, and there is an unmet need to estimate individuals' drug sensitivities.

Small cell carcinoma of the urinary tract is an aggressive malignancy that comprises less than 1% of urinary bladder cancers. The renal pelvis and ureter, also lined by urothelium, are rare sites for small cell carcinoma.

Small cell carcinoma of the urinary bladder (SCCB) is an extremely rare malignancy which is often associated with poor survival outcome. Literature reporting such disease is scarce. There is no standardised management.

To describe characteristics of pure small cell carcinoma of prostate (SCCP) and assess the prognostic factors.

We summarized data of pure SCCP from published studies and ours and made Kaplan-Meier analysis and Cox regression to evaluate prognosis factors.

Prostate cancer is the most common malignancy of men in the United States. Small-cell carcinoma (SCC), which typically presents as an aggressive lung malignancy, is a rare diagnosis within the setting of prostate cancer pathology.

Small cell carcinoma (SCC) of the prostate is an uncommon condition; there are very few cases in which presenting symptoms are consistent with Cushing Syndrome (CS). We report a new case in which CS triggers the suspicion of an SCC of the prostate and a review of the published cases of SCC of the prostate presenting with CS.

Small cell carcinoma (SmCC) of the bladder is a rare disease. We retrospectively studied a large series of bladder SmCC from a single institution. The patients included 69 men and 12 women with a mean age of 68years.

BACKGROUND - Extrapulmonary small cell carcinoma (SmCC), also known as oat cell carcinoma or small cell neuroendocrine carcinoma, is characterized by an aggressive clinical course with early metastasis pattern and a short life expectancy.

Small-cell carcinoma of the urinary bladder is a very rare pathology, but with a very aggressive behavior and disappointing prognosis. The literature concerning this type of cancer is scarce and physicians may encounter difficulty trying to manage it.

Prostate cancer is one of the most common cancers in the Western world. It is among the leading causes of cancer related death. While its incidence and survival increased significantly during the last few decades in Denmark, the mortality rate did not change for patients younger than 80 year old.

Urothelial carcinoma can exhibit a wide range of variant morphologies. Many variants present diagnostic challenges and carry clinical implications that inform prognosis and treatment decisions.

To provide an overview of the diagnostic, therapeutic, and prognostic significance of histological variants of urothelial carcinoma.
