Background: Serine-Arginine (SR) proteins are a conserved family of proteins involved in RNA splicing and are reported to be over-expressed in multiple cancers. The aim of the study is evaluation of the expression of Serine arginine protein kinase 1 (SRPK1) and Minichromosome maintenance protein 2 (MCM2) in epithelial ovarian cancer (EOC) and their correlation with clinicopathological features, response to therapy, progression-free survival (PFS), and cancer-specific survival (CSS).

Methods: This study was carried out on surgical specimens of 65 patients diagnosed with EOC which were submitted to immunohistochemical staining by SRPK1 and MCM2 antibodies.

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.

Perforator flaps are the latest development in reconstructive surgery. Pedicled chest wall perforator flaps can be utilized in many cases of partial breast reconstruction. This research compares the outcome and technique of thoracodorsal artery perforator flap (TDAP) and the lateral intercostal artery perforator flap (LICAP) in the reconstruction of partial breast defects.

Introduction: The use of cisplatin in clinical practice in the management of head and neck squamous cell carcinoma (HNSCC) is limited by its toxicity and acquired resistance, which makes the decision-making process of its prescription multifactorial.

Methods: An Egyptian expert panel (comprising nine Egyptian oncologists) meeting was held after a comprehensive literature review on the use of cisplatin in HNSCC. The panel aimed to develop a consensus on evidence-based recommendations for receiving cisplatin in the chemoradiotherapy management of HNSCC in Egyptian clinical practice.

Background: Breast conserving surgery (BCS) has been a standard procedure for the treatment of breast cancer instead of mastectomy whenever possible. Lateral chest wall perforator flaps are one of the volume replacement techniques that participate in increasing the rate of BCS especially in small- to moderate-sized breasts with good cosmetic outcome. In this study, we tried to evaluate the outcome of those flaps as an oncoplastic procedure instead of the conventional flaps.

Background: Clinical effectiveness and safety data of pazopanib in patients with advanced or mRCC in real-world setting from Asia Pacific, North Africa, and Middle East countries are lacking.

Methods: PARACHUTE is a phase IV, prospective, non-interventional, observational study. Primary endpoint was the proportion of patients remaining progression free at 12 months.

Article Synopsis
  • - The study investigates the presence of oncogenic viruses (HPV, EBV, and HMTV) in breast cancer patients and their relationship with clinical characteristics, based on samples from 80 Egyptian women with breast cancer and 30 control women.
  • - Results showed HPV in 41.25%, EBV in 37.5%, and HMTV in 41.25% of breast cancer patients, with no HPV or EBV found in controls, although HMTV was detected in 23.3% of them.
  • - It was concluded that WBCs might be a better sample type for detecting HMTV to minimize invasive procedures, and the presence of these viruses was linked to a younger age

Background: Due to the high variability of incidence and prevalence of intra-mammary lymph nodes (IMLNs), they might be overlooked during clinical and radiological examinations. Properly characterizing pathological IMLNs and detecting the factors that might influence their prevalence in different stages of breast cancer might aid in proper therapeutic decision-making and could be of possible prognostic value.

Methods: Medical records were reviewed for all breast cancer patients treated at the National Cancer Institute of Cairo University between 2013 and 2019.

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).

Breast conserving surgery (BCS) is currently the standard of care for early breast cancer. One of the key determinants for the line of treatment in breast cancer is the size of the tumor in relation to the breast size. The aim of this study is to determine the effect of the ratio of the excised specimen to breast volume on the cosmetic outcome after conventional BCS.

Background: Implant based reconstruction is one of the well-established methods to restore shape and volume after total mastectomy. Exposure of an implant is a serious complication that could lead to failure of the whole process of breast reconstruction. There are no uniform guidelines on the management of such complication.

Context: Chronic postmastectomy pain syndrome (PMPS) has a considerable negative impact on the quality of life of breast cancer patients.

Objective: The objective of this study was to assess the possible preventive role of perioperative pregabalin in PMPS.

Methods: This randomized controlled study included 200 patients with breast cancer scheduled for elective breast cancer surgery.

Entometrioid stromal sarcomas are seen in extra-uterine as well as extra-gonadal sites and have a strong association with endometriosis. Although having better prognosis than other sarcomas, yet these tumors may relapse (whether local or distant) in up to 56% of cases, even as late as 20 years after surgery. We report a case of a 30-year-old female patient with a mass in the inferior vena cava and right atrium which was surgically removed using cardiopulmonary bypass and deep hypothermic circulatory arrest and turned to be an entometrioid stromal sarcoma.

Background: Thoracodorsal artery perforator (TDAP) flap is one of the relatively new techniques in breast reconstruction. This pedicled flap retains the benefits of perforator flaps as regards minimal donor site morbidity without the need for microvascular anastomosis. Its role in partial breast reconstruction has been well documented.

Background: Malignant gastrointestinal neuroectodermal tumor (GNET) is an extremely rare entity that was first described by Zambrano et al. in 2003 as "Clear cell sarcoma-like tumor of the gastrointestinal tract". It shares some of the histological features of clear cell sarcoma (CCS) but lacks the immunohistochemical reactivity for melanocytic markers.

Background: The aim of this study is to compare the results of batwing mammoplasty and Wise pattern mammoplasty in the surgical management of upper pole breast tumours.

Methods: This is a retrospective observational study including 126 breast cancer patients who presented between 2009 and 2015 to the National Cancer Institute of Cairo University in Egypt. All patients were candidates for breast conservation, with upper pole tumours, which was defined as tumours between 3 and 9 o'clock.

Background: Maintenance therapy for non-small cell lung cancer (NSCLC) aims to extend disease control after first-line chemotherapy with active and well-tolerated agents. The utility of continuation maintenance therapy requires further research.

Methods: This multicenter, randomized, phase 2 study compared continuation maintenance therapy with pemetrexed (500 mg/m2 every 21 days) and best supportive care (BSC) versus BSC alone in patients with advanced, non-squamous NSCLC who had not progressed after 4 cycles of induction chemotherapy with pemetrexed (500 mg/m2) and cisplatin (75 mg/m2).

Background And Objectives: Relapsed, histologically aggressive non-Hodgkin lymphoma (NHL) has a poor prognosis; relapsed patients who do not respond to second line therapy or are unfit for BMT have a worse prognosis. Angiogenesis is increased in aggressive NHL and could be targeted by selective cyclooxygenase-2 inhibition and metronomic chemotherapy. We assessed the toxicity of metronomic chemotherapy and the response and progression-free survival in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL).
