Background Whether supplemental oxygen worsens long-term mortality remains unclear, with contradictory trial results. The authors therefore tested the hypothesis that (80% vs. 30%) increases hazard for mortality. Methods conducted a post hoc analysis of large multiple crossover cluster in which more than 5,000 colorectal surgeries on 4,088 adults were allocated to receive either 30% or 80% insp...

background: vascular endothelial growth factor (vegf) is a signal protein produced by cells that stimulates angiogenesis and increased vascular permeability. the prognostic value of vegf expression in colorectal cancer is unclear as shown by the discordant results still reported in the literature. this study was designed for the evaluation of vegf expression and correlation with clinicopatholog...

background colorectal cancer (crc) is the second most common malignancy in the world.  however, its mortality rate can be reduced if diagnosed early. p33 ing1b is a tumor suppressor protein, which plays a role in growth control and apoptosis. suppression of p33 ing1b is associated with the loss of cellular growth control. however, p33 ing1b expression in crc and its correlations with clinicopat...

background: improvement in complications of antitumor agents and surgery is important to enhance life quality and survival among patients with colon and colorectal cancer. it has been reported that some dietary components such as glutamine (gln) have beneficial effects on these complications of cancer therapies. however, the results of studies are inconsistent in this area. we performed a revie...

Abstract Background Since December 2019, China has experienced a public health emergency from the coronavirus disease, which become pandemic and is impacting care of cancer patients worldwide. This study evaluated impact on colorectal (CRC) at our center aimed to share lessons we learned with clinics currently experiencing this impact. Methods We retrospectively collected data CRC admitted betw...

Background: Robotic surgical systems were created partly to solve several constraints of laparoscopic surgery and offer technical advantages. With a substantial body evidence demonstrating its efficacy in rectal cancer treatment, robotic will soon become another conventional treatment. However, further investigations randomized trials focusing on primary endpoints are necessary establish some a...

abstract background: postoperative pain is an important surgical problem. recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia) it may be possible to prevent or reduce postoperative pain. this study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologi...

aim : to investigate association between mthfr gene polymorphism with colorectal cancer. background : the enzyme 5,10-methylene-tetrahydrofolate reductase (mthfr) is linked to dna methylation, synthesis and repair. one of the most important polymorphisms that has been identified in the mthfr gene is c677t. the single nucleotide polymorphism c677t has been found to be associated with decreased e...

hypermethylation of cpg islands located in the promoter regions of genes is a major event in the development of the majority of cancer types, due to the subsequent aberrant silencing of important tumor suppressor genes. klotho; a novel gene associated primarily with suppressing senescence has been shown to contribute to tumorigenesis as a result of its impaired function. recently the relevance ...

Synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. Globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. Vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...
