CONCLUSIONS SEER data analysis showed that women with uterine cervical cancer had some standard risk factors associated with bone metastases, and with prognosis, but a heterogeneous group of risk factors was also present. The findings of this study may have clinical application in screening for bone metastases in women with cervical cancer.

Publication date: October 2018Source: Seminars in Cancer Biology, Volume 52, Part 1Author(s): Bhupender Sharma, Shamsher S. KanwarAbstractCancer is a leading cause of mortality and morbidity globally. Many prominent cancer-associated molecules have been identified over the recent years which include EGFR, CD44, TGFbRII, HER2, miR-497, NMP22, BTA, Fibrin/FDP etc. These biomarkers are often used for screening, detection, diagnosis, prognosis, prediction and monitoring of cancer development. Phosphatidylserine (PS) is an essential component in all human cells which is present on the inner leaflet of the cell membrane. The oxi…

We report the first prospective clinical trial that utilized molecular profiling to select neoadjuvant therapy in patients with operable PDAC. Such high resectability rates have not been observed in prior neoadjuvant trials, suggesting that molecular profiling may improve the efficacy of chemotherapy in these patients.

Prostatic adenocarcinoma with focal pleomorphic giant cell features is rare with the only prior series consisting of 6 cases. From 2005 to 2018, we identified 29 cases from our consult service and 1 case from our own institution. Men ranged in age from 39 to 90 years (median=75.5). Diagnostic specimens consisted of needle biopsies (n=13); transurethral resections (n=7), urethral/bladder biopsies (n=8), radical prostatectomy (n=1), and orchiectomy (n=1). In all cases, there was usual acinar prostatic adenocarcinoma, where the highest grade in all cases was Gleason score 9 to 10 (Grade Group 5). On average, 68% of the involv…

We examined the immunohistochemical expression of SATB2 in 586 adenocarcinomas of the gastrointestinal (GI) tract and pancreas to assess its utility in diagnosis and analyze the clinicopathologic and molecular characteristics of colorectal carcinoma stratified by SATB2 expression. SATB2 and CDX2 expression were evaluated in 266 adenocarcinomas of lower GI tract origin (246 colorectal and 20 appendiceal mucinous), 208 adenocarcinomas of upper GI tract and small intestinal origin (74 esophagus/esophagogastric junction, 103 stomach, 20 duodenal, and 11 jejunoileal), and 112 pancreatic ductal adenocarcinomas. SATB2 expression …

ConclusionIncidentally detected gallbladder dysplasia in a cholecystectomy specimen, without any gross abnormality, has almost no risk of a hidden invasive carcinoma. Although cholecystectomy is sufficient treatment for gallbladder dysplasia, in our study cohort, 18.9% of cases with incidental dysplasia in gallbladder had an associated pancreatobiliary carcinoma, which supports the hypothesis of multifocal neoplastic potential in the pancreatobiliary tree (also known as field effect). Although follow-up on 16 cases shows no subsequent development of any other pancreatobiliary neoplasm, this number is probably not enough to…

In this study, we present a refined m6A MeRIP-seq protocol and analysis pipeline that can be applied to profile low-input RNA samples from patient tumors. We optimized the key parameters of m6A MeRIP-seq, including the starting amount of RNA, RNA fragmentation, antibody selection, MeRIP washing/elution conditions, methods for RNA library construction, and the bioinformatics analysis pipeline. With the optimized immunoprecipitation (IP) conditions and a postamplification rRNA depletion strategy, we were able to profile the m6A epitranscriptome using 500 ng of total RNA. We identified approximately 12,000 m6A peaks with a hi…

In conclusion, EMT-regulating microRNAs have great potential as liquid and solid biopsy markers in PDAC patients. Their prognostic and therapeutic benefits remain important tasks for future studies.
