Background/purpose: The aim was to evaluate the prognostic significance of postoperative radiotherapy (PORT) and surgical type on local recurrence-free survival (LRFS) and overall survival (OS) in triple-negative breast cancer (TNBC) in the Egyptian population.
Patients And Methods: We evaluated 111 patients with stage I-III TNBC diagnosed at our institute during the period from 2004 to 2009. Patients were stratified according to PORT into two groups: a PORT group and a non-PORT group. The influence of PORT and surgical type on LRFS and OS were evaluated. A cross-matching was done to the non-TNBC group of patients to compare the recurrence and survival rates between them and the studied group of TNBC patients.
Results: The mean age of TNBC patients at diagnosis was 63±7 years. The majority of the patients had stage III disease (68.5%) and 73% had clinical or pathological positive lymph nodes. Sixty percent (67/111) of patients had modified radical mastectomy and 44/111 (40%) patients had breast-conserving treatment. PORT was given for 63% of patients, while systemic treatment was given in 89% of patients. At the time of analysis, 13 patients (11%) developed local recurrence: five of 70 (7%) in the PORT group and eight of 41 (19.5%) in the non-PORT group. Five-year LRFS for the whole group of patients was 88%±6%, which was significantly affected by PORT. The surgical type did not affect local recurrence significantly. Five-year OS for the whole group was 54%±8%. PORT and surgical type did not affect OS significantly (P-value 0.09 and 0.11, respectively). Five-year LRFS was 88%±6% and 90%±11% for TNBC and non-TNBC patients, respectively (P-value 0.8); however, OS for TNBC was significantly lower than for non-TNBC (P-value 0.04).
Conclusion: TNBC is an aggressive entity compared with other non-TNBC, and these patients benefit from PORT significantly to decrease the risk of local recurrence in all stages. However, further large, prospective, randomized trials are warranted.

In recent years, robotic assistance has become increasingly used and applied in minimally invasive surgeries. A new cooperative surgical robot system that includes a joystick-guided robotic scope holder was developed in this study, and its feasibility for use in minimally invasive abdominal surgery was evaluated in a preclinical setting. The cooperative surgical robot consists of a six-degree-of-freedom collaborative robot arm and a one-degree-of-freedom bidirectional telescopic end-effector specializing in surgical assistance.

Many institutions perform thoracoscopic surgery for pediatric extrapulmonary sequestration (EPS). This approach achieves good cosmetic outcomes due to the small skin incision in comparison to open surgery. However, an extension or additional incision is sometimes necessary to extract resected specimens from the thoracic cavity, which reduces the advantages of this procedure.

Purpose: To evaluate an alternative surgical approach for Port Delivery System with ranibizumab (PDS) implant and a novel application of Iridex laser system in Gottingen minipig model.
Methods: A total of seventeen male minipigs (Part 1: 9 animals in non-recovery and Part 2: 8 animals observed for 8-days post-surgery Part 2) received PDS implant insertion into each eye. The effect of Iridex 810 nm infrared diode laser with varying energy (power or duration) on transscleral pars plana ablation, surrounding ocular tissue and postsurgical vitreous hemorrhage (VH) was investigated.
Background: This study evaluated the long surgical gauze (SurG) technique as a liver retraction method in laparoscopic sleeve gastrectomy (LSG). Traditional methods involve the Nathanson retractor, associated with ischemia and necrosis complications. In addition, these techniques require an additional trocar with an incision that increases postoperative pain.

Giant ovarian cysts (GOCs) have become less common in developed countries due to routine health screenings, but they remain prevalent in economically underdeveloped regions. Treatment options for GOCs depend on factors such as age, cyst characteristics, and pregnancy status. Minimally invasive single-port laparoscopic surgery has largely replaced traditional open surgery due to its aesthetic advantages and effectiveness.
