Pathogenic/likely pathogenic (P/LP) germline variations in BRCA1 and BRCA2 genes are responsible for the majority of hereditary breast and ovarian cancers. This study presents the BRCA1/BRCA2 sequencing and deletion duplication analyses results of of 493 participants (485 women, 8 men) selected based on the National Comprehensive Cancer Network (NCCN) guidelines.

Next generation sequencing (NGS) and multiplex ligation-dependent probe amplification methods (MLPA) were used to define germline BRCA1/BRCA2 positivity.

Overall, the P/LP frequency of the participants was 17.8%. Five of the likely pathogenic variants were novel. The 5266dupC pathogenic variation, which is a founder mutation in the Ashkenazi Jewish population, was the most common variation among the patients, with a frequency of 5.47%. find more The pathogenic/likely pathogenic variation frequency was significantly higher (p=0.01) among clinically diagnosed familial cancer patisents than those participants without personal history of cancer but enrolled ation, as the most common pathogenic variation in the Trakya region of Turkey, should be included if a targeted mutatin screening is planned.

To investigate the anticancer properties of a well-known naturally occurring sesquiterpene lactone - artemisinin - against cisplatin resistant human breast carcinoma cells along with examining its effects on apoptosis, autophagy as well as cell cycle phase distribution.

MTT assay was used to study cytotoxic effects of artemisinin while clonogenic assay analysed its effects on cancer cell colony formation. Fluorescence microscopy using DAPI staining was employed to study apoptotic effects of artemisinin which was followed by annexin V/propidium iodide (PI) assay which quantified the apoptotic effects of artemisinin in cancer cells. Apoptotic effects of artemisinin were finally confirmed by western blot assay by analysing its effects on Bcl-2 and Bax protein expressions. Effects of artemisinin on autophagy were determined by transmission electron microscopy (TEM). Effects on cell cycle were analysed by flow cytometry and western blot.

The results indicated that artemisinin led to considerable and dose-deprrest.

This study was performed to investigate the effects of lanostane against human breast cancer cells with emphasis on its potential to inhibit cancer cell growth and metastasis along with understanding the underlying molecular mechanism mediating the effects.

The SK-BR-3 normal breast line and the MB-157 breast cancer cell line were used in this study. MTT of cell growth was used to determine the viability of cells under lanostane treatment. Colony formation assay was used to analyze the clone forming capability of cancer cells when treated with lanostane. DAPI and acridine orange (AO)/ethidium bromide (EB) staining assays were performed for assessing the apoptic cell death. The level of cellular apoptosis was further examined using flow cytometry. Wound healing and transwell assays were performed to determine the migration and invasion of cancer cells. Western blotting was used for determining the concentration of proteins of interest.

The lanostane treatment of cancer cells resulted in loss of cell viabgainst various human malignancies.

The results of the present study are suggestive of anticancer effects of lanostene triterpene which exerted its effects by inhibiting cell proliferation and metastasis of breast cancer cells mediated through inactivation of Rho-associated kinase signaling. The study holds promise to provide a lead for exploring the secondary metabolite-based anticancer approach against various human malignancies.

To compare two hypofractionated radiation schedules in early breast cancer concerning skin toxicity.

We retrospectively analyzed 80 patients (group A) versus 54 (group B) who underwent hypofractionated radiotherapy after breast conserving surgery. Group Α received 42.75Gy in 15 fractions over 5 weeks (3 fractions/ week) plus 8.55Gy boost to the tumor bed (3 fractions). Group Β received 45.05Gy (5 fractions/week) and 7.95Gy boost (3 fractions). Multivariate logistic regression analysis (MVLRA) was conducted for relevant parameters regarding RTOG/EORTC skin toxicity.

Median follow up was 60 months. Median age was 75 years (group A) and 56 (group B). Mean values of radio-dermatitis were significantly higher in group A vs B until 3 months post RT (p<0.001 and p=0.002, respectively), while 6 months thereafter toxicity was regressed without any significant difference between groups. MVLRA showed a significant (p<0.001) odds ratio for age (2.36, 95%CI1.11-3.75) and group A (1.31, 95%CI1.12-1.49).

Schedule B would be preferable in younger women in favor of toxicity. Schedule A could still be applied in elderly patients, unavailable attending daily schedules, with acceptable toxicity.

Insulinomas are most commonly benign, well-differentiated NETs, whereas malignant neoplasms account for approximately 5-10% of all cases. Management includes conservative treatment with drugs targeting insulin-induced hypoglycemia, non-operative invasive procedures, as well as curative open or laparoscopic tumor resection. The current review aimed to summarize the current literature evidence on insulinoma and investigate the advantages and complications of available treatments.Breast cancer (BC) remains the most frequently diagnosed malignancy among women worldwide. Recognized predisposing factors may be absent in the majority of affected patients, which has aroused a stronger interest in identifying risk parameters that contribute to BC pathogenesis. Human papilloma virus (HPV) infection is strongly associated with malignancies, such as cervical cancer, oropharyngeal cancer and anal cancer. Various surveys have linked HPV to the development of BC. Relevant variations in HPV identification among BC samples may be attributed to differences in study design, the populations involved and the HPV detection techniques applied, which are still controversial with conflicting opinions and results that deny the causative association between HPV infection and BC development. Furthermore, the role of HPV, a potential cause of human BC, has recently received more attention because of the possible restriction of disease progression using an HPV vaccine. The aim of this review was to evaluate both the aspects supporting and those against the theory of BC related to HPV infection.
