Background: Breast cancer is the second most common malignancy diagnosed in pregnancy. Breast cancer in pregnancy represents a challenge in diagnosis as well as in treatment.
Objective: To evaluate clinically patients with breast cancer in pregnancy. METERIAL AND METHODS: Retrospective, transversal, descriptive study was done in which we enrolled women with breast cancer and pregnancy from the outpatient clinic of medical oncology of a tertiary care center hospital. Statistical analysis: descriptive statistics.
Results: The variables of 15 clinical records were examined, median age 33.3 ± 5.5 years, tobacco use 3/15, oral contraceptives use 2/15, age at first birth 25.8 ± 7 years, breastfed 4/15. The initial medical evaluation was done 7.5 ± 7.7 months after the onset of symptoms, the diagnosis was made with trucut biopsy in 9/15 of patients, excisional biopsy 4/15 and fine needle aspiration biopsy 2/15. Clinical stage was IIA 3/15, IIIA 8/15, IIIB 3/15 and IV 1/15. Six patients were treated with chemotherapy during pregnancy in the second and third trimester and three with surgical treatment. There were no fetal deaths related to treatment. Response to treatment: 8/15 are disease-free, 5/15 progressed to death and 2/15 had bone metastasis.
Conclusion: Even major cancer centers have limited experience with breast cancer in pregnancy. Medical and surgical treatment should not be differed. More prospective studies are needed to assess factors related to treatment and prognosis.

This study presents T-1-NBAB, a new compound derived from the natural xanthine alkaloid theobromine, aimed at inhibiting VEGFR-2, a crucial protein in angiogenesis. T-1-NBAB's potential to interacts with and inhibit the VEGFR-2 was indicated using in silico techniques like molecular docking, MD simulations, MM-GBSA, PLIP, essential dynamics, and bi-dimensional projection experiments. DFT experiments was utilized also to study the structural and electrostatic properties of T-1-NBAB.

The maturation of the RNA cap involving guanosine N-7 methylation, catalyzed by the HsRNMT (RNA guanine-7 methyltransferase)-RAM (RNA guanine-N7 methyltransferase activating subunit) complex, is currently under investigation as a novel strategy to combat PIK3CA mutant breast cancer. However, the development of effective drugs is hindered by a limited understanding of the enzyme's mechanism and a lack of small molecule inhibitors. Following the elucidation of the HsRNMT-RAM molecular mechanism, we report the biophysical characterization of two small molecule hits.

Introduction: Outpatient cancer counseling centers (OCCs) are important social work facilities that provide support for cancer survivors who have psychosocial and sociolegal challenges. This paper explores clinical and sociodemographic characteristics, psychosocial burden as well as access routes of clients in OCCs seeking work-related counseling.
Methods: Between May 2022 and December 2023, data were collected in 19 OCCs, using questionnaires and documentation by counselors.
New Oral Selective Estrogen Receptor Degraders Redefine Management of Estrogen Receptor-Positive Breast Cancer.

Oral selective estrogen receptor degraders (SERDs) are pure estrogen receptor antagonists that have the potential to overcome common resistance mechanisms to endocrine therapy in estrogen receptor-positive breast cancer. There are currently five oral SERDs in published and ongoing clinical trials-elacestrant, camizestrant, giredestrant, imlunestrant, and amcenestrant-with more in development. They offer a reasonably well-tolerated oral therapy option with low discontinuation rates in studies.

The cysteine-rich epidermal growth factor ligand domain 2 protein (CRELD2) is associated with pathways that regulate epithelial-to-mesenchymal transition, a critical process driving cancer metastasis. This study aimed to determine the prognostic value of CRELD2 status on survival outcomes in triple-negative breast cancer (TNBC). Seventy patients were included in the study.
