Anastomosing hemangioma of the ovary - a comprehensive review of this rare ovarian entity.

Background: Anastomosing hemangioma of the ovary is a rare vascular tumor that predominantly affects middle-aged women. Despite its benign nature, its histological appearance can mimic aggressive vascular lesions, posing diagnostic challenges. This review aims to provide an overview of this uncommon entity.

Clinical and Analytical Validation of Two Methods for Ki-67 Scoring in Formalin Fixed and Paraffin Embedded Tissue Sections of Early Breast Cancer.

Proliferation determined by Ki-67 immunohistochemistry has been proposed as a useful prognostic and predictive marker in breast cancer. However, the clinical validity of Ki-67 is questionable. In this study, Ki-67 was retrospectively evaluated by three pathologists using two methods: a visual assessment of the entire slide and a quantitative assessment of the tumour margin in 411 early-stage breast cancer patients with a median follow-up of 26.

Association of androgen receptor and tumour-infiltrating lymphocytes with bone recurrence in triple-negative breast cancer.

Background: As compared to endocrine responsive breast cancer bone is less frequent site of distant recurrence in triple-negative breast cancer (TNBC). A biomarker which predicts bone recurrence would allow a more personalized treatment approach with adjuvant bisphosphonates in TNBC. Here we hypothesised that tumour expression of androgen receptor (AR) is associated with bone recurrence in TNBC.

The Possible Role of Anti- and Protumor-Infiltrating Lymphocytes in Pathologic Complete Response in Early Breast Cancer Patients Treated with Neoadjuvant Systemic Therapy.

The tumor microenvironment, composed of pro- and antitumor immune cells, affects cancer cell behavior. We aimed to evaluate whether tumor-infiltrating lymphocyte (TIL) density and TIL subtypes in core biopsies at the diagnosis of breast cancer patients could predict a pathologic complete response (pCR; ypT0/is ypN0) from neoadjuvant systemic therapy (NST). The TIL subtypes were determined based on the proportions of presumably antitumor (CD8+, CXCL13+) and protumor (PD-1+, FOXP3+) immune cells.

Complete response in the axilla and the non-triple negative subtype are favourable prognostic factors for survival outcomes in inflammatory breast cancer.

Aim: To assess real-world outcomes and prognostic factors of non-metastatic inflammatory breast cancer according to immunohistochemistry (IHC)-based subtype and treatment regimen.

Methods: An institutional retrospective analysis of patients treated with neoadjuvant systemic treatment (NAST) for stage III inflammatory breast cancer diagnosed between 2001 and 2018 was performed. The survival outcomes in relation to patient characteristics, tumour characteristics, treatment modality and response to NAST were analyzed.
