BCL-2 expression in IBC; NST has different prognostic effects depending on the molecular subtype of the cancer. In cancers with a HER2-enriched phenotype, BCL-2 expression was a marker of poor prognosis, while in cancers with a hormone receptor-positive phenotype, BCL-2 expression had a better prognostic impact.

Conclusion Axl receptor was not associated with all of the clinicopathological variables, the expression values were high in malignant tumors in comparison with the benign tumors, and it was found that Axl receptor expression was associated with low/intermediate grade, which is considered a favorable prognostic factor. Although Axl receptor expression was previously linked with proliferation and invasiveness in BC, its association with the Ki-67 proliferation marker and BCL-2 anti-apoptotic protein was not observed.

BCL-2 expression is observed with a relatively similar frequency in DPE and SEH samples, and it is probably under the control of oestrogen hormone as the main factor involved in the pathogenesis of these lesions.

We provide evidence that BCL2 expression is regulated by DNA methylation, associated with epithelial-mesenchymal transition, and increased by the neuronal transcription factor ASCL1. Finally, BCL2 inhibition had antitumor activity in some, but not all, BCL2-positive PC models, highlighting the need for combination strategies to enhance tumor cell apoptosis and enrich response.

Expression of Bcl-2, an antiapoptotic protein, is associated with low-grade, slowly proliferating, luminal A-type BC. IHC analysis of Bcl-2 is simple, inexpensive, readily available test to stratify early-stage hormone-positive patients who can be included in clinical trials for Bcl-2 inhibitors.

In poorly differentiated oral squamous cell carcinoma Bcl-2 positivity was high and low in well-differentiated oral squamous cell carcinoma. Bcl-2 expression was higher in severe dysplasia compared to moderate dysplasia, which may indicate aggressive behaviour of tumour in poorly differentiated oral squamous cell carcinoma and severe dysplasia.

We report a case of primary pulmonary DLBCL caused by methotrexate-associated lymphoproliferative disorder (MTX-LPD)...MTX-LPD was suspected, and discontinuation of the drug resulted in subsequent shrinkage of the residual tumor. If the diagnosis cannot be made by transbronchoscopic biopsy of an expanding nodule shadow, aggressive surgical diagnosis should be considered.

Because continuous inhibition of BCL-XL causes thrombocytopenia, we proposed and tested an interrupted 4 days ON / 3 days OFF treatment regimen, which retained the desired anti-tumor synergy with manageable platelet toxicity. The proposed VEN and A1155463 combination represents an innovative chemotherapy-free regimen with significant preclinical activity across diverse BCL2-positive hematologic malignancies irrespective of the BCL1L11/BIM status.

The classically described ivory-white gross appearance of the tumor, histomorphology of thick bands dividing the tumor into lobules, squamous cell differentiation, tight whorls of cells resembling Hassall's corpuscle, and areas showing dense lymphocytic infiltration, together with an immunoprofile of CD5, Ckit, Tumor protein 63 (p63), and B-cell lymphoma 2 gene (bcl2) positivity, helped in diagnosing this rare entity. Though classically ITC is said to have a good prognosis, cases with spread to adjacent organs and lymph node metastasis may not have an indolent course.

We conclude that proportion of positive stains can be regressed using attention-based multiple instance learning, that these models generalize well to whole slide images, and that our models can provide non-inferior stratification of progression-free survival outcomes.
