Background: Stage III non-small cell lung cancer (NSCLC) being highly heterogeneous requires multimodal therapeutic strategies for optimal management. We present findings on treatment patterns and their associated survival outcomes in patients with stage III NSCLC from the Egypt subset of the KINDLE global real-world study conducted across countries from Asia, Middle East, Africa, and Latin America.

Method: Retrospective data from the Egypt subset (21 centers) of adult patients diagnosed with stage III NSCLC between January 2013 and December 2017 were analyzed.

Background: Many issues need to be studied regarding pregnant women during the SARS-CoV-2 (COVID-19) infection pandemic. The aim of this study was to assess fetal growth, fetal well-being, and any observed gross anomalies that may follow SARS-CoV-2 infection in Egyptian pregnant women. During fetal anomaly scan at 22 weeks, we compared 30 pregnant women with a history of SARS-CoV-2 infection at 6‑12 weeks of gestation (group A) with 60 pregnant women (group B) who had no history of SARS-CoV-2.

Background: Women's fecundity is known to decrease with the increase in chronologic age. Several biomarkers of the ovarian reserve, including follicle stimulating hormone (FSH), anti Müllerian hormone (AMH), have been proposed as possible predictors for the response to controlled ovarian stimulation (COS). Although there are assumptions indicating that the relationship between age and ovarian reserve is highly variable and the potential different validity of ovarian reserve markers in women in different age groups remains to be demonstrated.

The therapeutic landscape of human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (mBC) has evolved considerably with the introduction of newer targeted agents such as poly-ADP ribose polymerase inhibitors (PARPi), novel chemotherapeutic agents, immunotherapy, and endocrine therapies. In this scenario, optimizing the appropriate treatment sequence is a daunting task for clinicians. To develop evidence-based answers to key clinical questions on treatment selection and appropriate treatment sequence for the management of patients with HER2- mBC in the era of PARPi, a breast cancer expert group meeting was convened.

Unlabelled: Cryopreservation of human embryos has become an essential part of assisted reproduction. It limits the number of embryo transferred while supernumerary embryos can be transferred in subsequent cycles, however, it is associated with zonal hardening, which lowers the success rate in the majority of (ICSI) centres, associated with decreased implantation rate and clinical pregnancy rates. Assisted hatching has been used to induce microdissection of the zona pellucida.

Purpose: In view of the documented toxicity of continuous daily radiosensitizer doses of temozolomide concomitant with radiation in the treatment of glioblastoma multiforme, we aimed to compare it with a different schedule of abbreviated radiosensitizer dosing.

Patients And Methods: This was a randomized prospective study comparing toxicity and survival in 60 Egyptian patients with glioblastoma multiforme. Patients in arm I received temozolomide at a dose of 75 mg/m(2) daily with radiotherapy for 42 days, starting 4 weeks after surgery and reaching to a total radiation dose of 60 Gy/30 Fractions/6 weeks, while patients in arm II received temozolomide at a dose of 75 mg/m(2) concomitantly with the same radiotherapy schedule daily in the first and last weeks of the same radiotherapy program.

Introduction: Based on the variable benefit of taxanes in the adjuvant setting of early breast cancer in certain tumor phenotypes, especially in human epidermal growth factor receptor (HER)2-positive and triple-negative disease, and with the observation of a lesser benefit in luminal A, this research article aimed at exploring the value of docetaxel in patients with an estrogen receptor-positive, HER2-negative disease phenotype, who might not derive the same benefits as those with other phenotypes.

Patients And Methods: This was a randomized prospective study comparing disease-free survival (DFS) and safety profile of sequential adjuvant three cycles Fluorouracil, Epirubicin, Cyclophosphamide followed by three cycles Docetaxel (FEC-D) versus six cycles classic Fluorouracil, Epirubicin, Cyclophosphamide (FEC)-100 in 60 Egyptian women who presented to Dar Al Fouad Hospital during the period June 2007 to July 2008 with (pT1-2 pN0-3 M0). The primary end point was DFS in a follow-up period of 4 years.

Purpose: The majority of Egyptian patients with lung cancer present at a late stage of the disease. Bevacizumab/carboplatin/paclitaxel, as well as cisplatin plus pemetrexed, are both standard regimens for advanced non-squamous bronchogenic cancer. This study compares both regimens, in terms of efficacy and toxicity profile, in Egyptian patients.

Purpose: In view of the previous reports demonstrating the positive outcome of bevacizumab in metastatic breast cancer, we aimed at comparing the role of bevacizumab-based metronomic combination with taxane (paclitaxel) versus a different taxane (docetaxel)-based regimen in addition to carboplatin as initial treatment for metastatic Her-2-negative breast cancer.

Patients And Methods: This is a randomized Phase III study comparing the progression-free survival (PFS) and safety in Her-2-negative female patients with initial diagnosis of metastatic breast cancer with World Health Organization performance status of 0-II. Forty-one patients were randomized from September 2008 to July 2009 to receive either; (1) bevacizumab 5 mg/kg day 1 and day 15, carboplatin area under the curve (AUC)-2 day 1, day 8, and day 15, and paclitaxel 60 mg/m(2) day 1, day 8, and day 15 (arm-I); or (2) carboplatin AUC-5 day 1, docetaxel 75 mg/m(2) day 1 (arm-II).

Background: Radiotherapy is effective in controlling pain from bone metastases which is a direct result of bone resorption. The urine resorption marker DPD proved important in assessing effectiveness of palliative radiotherapy to bone metastases. There is still controversy about the optimum adopted fractionation regimen.
