Histologic features of stromogenic carcinoma of the prostate (carcinomas with reactive stroma grade 3).

Prostatic carcinoma, like many other carcinomas, generates a stromal reaction. This phenomenon is well established in the scientific literature. The normal parenchymal smooth muscle phenotype switches to a myofibroblastic phenotype in response to the presence of cancer cells, with an expansion of the extracellular matrix compartment.

New pattern-based personalized risk stratification system for endocervical adenocarcinoma with important clinical implications and surgical outcome.

We present a recently introduced three tier pattern-based histopathologic system to stratify endocervical adenocarcinoma (EAC) that better correlates with lymph node (LN) metastases than FIGO staging alone, and has the advantage of safely predicting node-negative disease in a large proportion of EAC patients. The system consists of stratifying EAC into one of three patterns: pattern A tumors characterized by well-demarcated glands frequently forming clusters or groups with relative lobular architecture and lacking destructive stromal invasion or lymphovascular invasion (LVI), pattern B tumors demonstrating localized destructive invasion (small clusters or individual tumor cells within desmoplastic stroma often arising from pattern A glands), and pattern C tumors with diffusely infiltrative glands and associated desmoplastic response. Three hundred and fifty-two cases were included; mean follow-up 52.

Invasive endocervical adenocarcinoma: a new pattern-based classification system with important clinical significance.

A new 3-tier pattern-based system to classify endocervical adenocarcinoma was recently presented. In short, pattern A tumors were characterized by well-demarcated glands frequently forming clusters or groups with relative lobular architecture. Pattern B tumors demonstrated localized destructive invasion defined as desmoplastic stroma surrounding glands with irregular and/or ill-defined borders or incomplete glands and associated tumor cells (individual or small clusters) within the stroma.

Clinical performance of hybrid capture 2 human papillomavirus testing for recurrent high-grade cervical/vaginal intraepithelial neoplasm in patients with an ASC-US Papanicolaou test result during long-term posttherapy follow-up monitoring.

Context: Women who have been treated for high-grade cervical or vaginal intraepithelial neoplasia (CIN or VAIN) or invasive carcinoma are at risk for recurrent/persistent disease and require long-term monitoring. The role of human papillomavirus (HPV) testing in this setting is unclear.

Objective: To evaluate the clinical performance of the Hybrid Capture 2 (HC2) HPV test for recurrent/residual high-grade CIN or VAIN in patients with a posttherapy abnormal squamous cells of undetermined significance (ASC-US) Papanicolaou test result.

Invasive endocervical adenocarcinoma: proposal for a new pattern-based classification system with significant clinical implications: a multi-institutional study.

The management of endocervical adenocarcinoma is largely based on tumor size and depth of invasion (DOI); however, DOI is difficult to measure accurately. The surgical treatment includes resection of regional lymph nodes, even though most lymph nodes are negative and lymphadenectomies can cause significant morbidity. We have investigated alternative parameters to better identify patients at risk of node metastases.

Pim-2 upregulation: biological implications associated with disease progression and perinueral invasion in prostate cancer.

Background: The serine/threonine kinase Pim-2 acts as a transcriptionally regulated apoptotic inhibitor and is implicated in prosurvival. Pim-2 has been implicated in many apoptotic pathways.

Materials And Methods: Silencer validated short interfering RNA (siRNA) to Pim-2, Silencer GAPDH siRNA, and one scrambled siRNA for eliciting RNAi were transfected separately into DU-145/DRG in vitro model.
