The impact of loco-regional treatment modality on the outcomes in breast cancer patients younger than forty years of age.

Purpose: To determine the impact of the loco-regional treatment modality, on the loco-regional recurrence (LRR) rates and overall survival (OS) in breast cancer patients younger than 40 years.

Methods: Data of 623 breast cancer patients younger than 40 years of age were retrospectively reviewed. Patients were stratified according to the locoregional treatment approach into three groups: the mastectomy group (M), the mastectomy followed by radiation therapy group (MRX) and the breast conservative therapy group (BCT).

Phyllodes tumors of the breast: Adjuvant radiation therapy revisited.

Background: Phyllodes tumors (PT) are rare entity and surgical resection is the cornerstone of treatment. No standard of care exists regarding adjuvant treatment especially radiation therapy (RT).

Patients And Methods: We analyzed all patients with non-metastatic, resected phyllodes tumors who presented to our institution from January 2005 through December 2019.

Once Daily Versus Twice Daily External Beam Accelerated Partial Breast Irradiation: A Randomized Prospective Study.

Purpose: The aim of the current study was to compare toxicity, cosmesis, and local control between the once daily and the twice daily fractionation schemes for external beam accelerated partial breast irradiation.

Methods And Materials: From December 2012 to June 2018, we enrolled 113 patients with ductal carcinoma in situ or invasive breast cancer, node negative disease, and tumors less than 3 cm in size to receive accelerated partial breast irradiation (APBI) to a total dose of 38.5 Gy over 10 fractions given either once (oAPBI) or twice daily (tAPBI).

Prevalence of Human Papillomavirus (HPV) Infection and the Association with Survival in Saudi Patients with Head and Neck Squamous Cell Carcinoma.

Head and neck squamous cell carcinoma (HNSCC) shows wide disparities, association with human papillomavirus (HPV) infection, and prognosis. We aimed at determining HPV prevalence, and its prognostic association with overall survival (OS) in Saudi HNSCC patients. The study included 285 oropharyngeal and oral-cavity HNSCC patients.

Effects of nicotine on rat adrenal gland: crosstalk between oxidative and inflammatory markers, and amelioration by melatonin.

Although the risks of smoking are well known, the effects of exposure to nicotine on endocrine functions remain unclear. We investigated the deleterious effects of nicotine on the adrenal gland and the mechanisms of these changes in rats. The role of melatonin in ameliorating pathological changes also was investigated.
