BACKGROUND: Patients with bladder cancer undergoing radical cystectomy (RC) experience high rates of perioperative blood transfusions (PBTs) and morbidity. The aim of this study was to evaluate the effect of blood storage duration on the risk of adverse perioperative outcomes in this high-risk patient population. MATERIALS AND METHODS: In a retrospective review of RC patients from 2010 to 2014 who received PBTs, the average storage duration for all units transfused was used to classify patients as receiving older blood using 3 different definitions (≥21 days,≥28 days, and≥35 days)...

Since 'radical lobectomy' was reported by Cahan in 1960, the standard surgical care for lung cancer has been lobectomy, in which units of the lobe are excised with their specific regional hilar and mediastinal lymphatics. However, pulmonary function-preserving limited resection for lung cancer has gradually become more prevalent in the late 20th century. In 1995, Ginsberg et al. conducted a randomized controlled trial in which limited resection (segmentectomy and wide-wedge resection) and lobectomy for stage I lung cancer were compared and reported that limited resection should not be applied to healthy patients with clinical stage IA lung cancer...

In recent decades, our understanding of thyroid cancer has improved significantly with the recognition that differentiated thyroid cancer (DTC) has good survival and oncological outcomes. Along with the recent rise in the detection of otherwise subclinical tumours due to improved diagnostics, there has been much debate on how aggressive one should be when performing thyroid and lymph node surgery. The use of risk stratification to categorize patients into low, intermediate and high risk has led to a more tailored approach to treating differentiated thyroid cancer...

Robot-assisted gastrectomy has been reported to be a safe alternative to both conventional laparoscopy and the open approach for treating early gastric carcinoma. Currently, there are a limited number of published reports on this technique in the literature. We assessed the current status of robotic and laparoscopic surgery in the treatment of gastric cancer and compared the operative outcomes, learning curves, and oncological outcome of the two approaches. Robotic gastrectomy offers benefits that include increased ease of performing D2 lymph node dissection and reduced blood loss compared with laparoscopic gastrectomy...

Cerenkov luminescence imaging (CLI) is a novel molecular optical imaging technique based on the detection of optical Cerenkov photons emitted by positron emission tomography (PET) imaging agents. The ability to use clinically approved tumour-targeted tracers in combination with small-sized imaging equipment makes CLI a particularly interesting technique for image-guided cancer surgery. The past few years have witnessed a rapid increase in proof-of-concept preclinical studies in this field, and several clinical trials are currently underway...

Recent advances in the surgical treatment of early stage non-small cell lung cancer (NSCLC) have focused heavily on making procedures less invasive, less radical, and better tolerated. Advances in accuracy and increased utilization of cross-sectional imaging allows for diagnosis of smaller and more indolent tumors and preinvasive lesions. Similar to advanced disease, early-stage treatment is now being tailored to individual patients and their tumors. Sublobar resections are gaining acceptance as an oncologically equivalent approach to lobectomy in well-selected stage I patients...

BACKGROUND: Esophageal resection for cancer (EC) is still associated with considerable mortality and morbidity rates. Allogenic blood transfusion (aBT) is associated with poor short-term and long-term outcome in surgical oncology. We aimed to evaluate the effect of aBT in a homogeneous population of EC patients undergoing esophagectomy without perioperative treatment. METHODS: We analyzed 565 esophagectomies performed due to EC. Allogenic blood transfusion was correlated to clinicopathological parameters, perioperative mortality and morbidity as well as the long-term outcome...
