Abstract
The object of this study was to evaluate the relationship between oxidative damage induced by oxaliplatin (OXA) and the therapeutic potential of 7-chloro-4-(phenylselanyl) quinoline (4-PSQ) in kidney of mice. Mice received OXA (10 mg/kg) or vehicle intraperitoneally (days 0 and 2). Oral administration of 4-PSQ (1 mg/kg) or vehicle was performed on days 2 to 14. On day 15 the animals were euthanized and the kidneys and blood were collected. The effect of OXA and (or) 4-PSQ on urea, thiobarbituric acid reactive species, nonprotein thiol (NPSH), and protein carbonyl (PC) levels were investigated. Moreover, renal superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione S-transferase (GST), δ-aminolevulinic acid dehydratase (δ-ALA-D), and Na+,K+ ATPase activities were evaluated. Our findings revealed an increase on urea levels and significant renal oxidative damage in OXA-induced mice. OXA exposure increased SOD, GPx, and GST activities and caused a reduction on NPSH levels and CAT and GR activities. Na+,K+ ATPase and δ-ALA-D activities were reduced by OXA. 4-PSQ decreased plasmatic urea levels and renal oxidative damage. SOD, GPx, CAT, GR, and Na+,K+ ATPase activities were restored by 4-PSQ. 4-PSQ may be a good prototype for the treatment of OXA-induced renal injury.

Abstract
BACKGROUND Management of patients with colorectal cancer (CRC) is about not only survival, but also quality of life (QoL). What patients want is important but is not well researched or understood for elderly patients where it is very relevant. This study aimed to measure and compare what patients with CRC aged 80 and over and surgeons consider important in terms of survivorship after surgery for CRC. METHODS Patients aged 80 and over who were having surgery for CRC were recruited and interviewed using closed and open questions about their expectations of surgery and various QoL dimensions. These were assessed preoperatively and 3 months post-operatively. Surgeons ranked the same QoL dimensions of patients by questionnaire. RESULTS Nineteen patients (median age 87.5, range 80-95, eight males and 11 females) were recruited. Patients rated items relating to health, mobility and independence (n = 23) as top three items most often followed by people outside self (n = 13). Surgeons underestimated importance in 17 domains with the biggest discrepancy being in 'avoiding a stoma' (4.11 versus 2.3, P < 0.01). CONCLUSION With patients over 80 years having surgery for CRC, there is a lack of concordance between what surgeons think is important and what patients think is important. Despite this, CRC patients aged 80 and older are almost always satisfied with the outcome of surgery. Surgeons should ensure that they understand patients' expectations and that they are aligned with likely outcomes of surgery.

Abstract
Background/Aims Colorectal cancer (CRC) patients often exhibit peritoneal metastasis, which negatively impacts their prognosis. CD31 and D2-40 have recently been suggested to be predictors of breast cancer prognosis, but their role in colorectal peritoneal metastasis (CRPM) remains unknown. Methods The expression profiles of CD31 and D2-40 were analyzed in CRC patients with or without CRPM and in CRC cell lines with increasing metastatic potential. Overexpression and short hairpin RNA knockdown assays were performed in CRC cells, and the effects of these alterations on epithelial-mesenchymal transition (EMT) in vitro, growth of xenograft tumors in vivo, and peritoneal metastasis potential in a mouse model of CRPM were examined. Results The expressions of CD31 and D2-40 were upregulated in CRC tumor tissues and was elevated further in tumor tissues from patients with CRPM. CD31 and D2-40 expression levels exhibited increasing trends parallel to the EMT potential of CRC cells. CD31 and D2-40 are essential for CRC cell EMT in vitro as well as for xenograft tumor growth and peritoneal metastasis in vivo. Conclusions CD31 and D2-40 contribute to CRPM by promoting EMT and may serve as prognostic markers and therapeutic targets for CRC, particularly in patients with peritoneal metastasis.

Abstract
INTRODUCTION Chemotherapy-induced hepatotoxicity in cancer patients often results in cessation of therapy and prevents completion of the treatment plan. The entire pathological description and comparison of hepatic damage induced by oxaliplatin or cisplatin in combination with 5-fluorouracil (5-FU) is not adequately reported. This study reports histopathological assessment of hepatotoxicity of a non-tumor bearing organ in rats treated with 5-FU, oxaliplatin and cisplatin (CDDP). MATERIAL AND METHODS Changes in hepatic biochemical profile of 36 albino Wistar rats equally divided into different treatment groups with cisplatin, oxaliplatin, 5-FU, cisplatin plus 5-FU and oxaliplatin plus 5-FU were compared with a group of rats treated with normal saline (control group). At the end of treatments, hepatic tissues were taken for blinded histopathological assessment by light microscopy. RESULTS Serum glutamate pyruvate transaminase and serum glutamic-oxaloacetic transaminase levels were disrupted in rats treated with 5-FU alone and in combination with cisplatin or oxaliplatin. Hepatocellular injuries, e.g. sinusoidal dilatation, venular fibrosis and centrilobular vein injury induced by oxaliplatin were intensified in treatment groups also receiving 5-FU, manifested as massive architectural distortion, periportal fibrosis, hepatic cord degeneration and cystic lesions with demarcated margins. Hepatocellular degenerative sequence and abnormally dilated central hepatic vein was shown in the cisplatin plus 5-FU treatment group with hemorrhage and blood filled sinusoids. CONCLUSIONS Oxaliplatin-associated cystic lesions were intensified in rats treated with a combination of 5-FU and oxaliplatin.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common malignancies worldwide, with high morbidity and mortality rates. The purpose of this study was to identify potential biomarkers in the progression of CRC. MATERIAL AND METHODS Gene and isoform expression datasets of CRC was downloaded from The Cancer Genome Atlas (TCGA). EBSeq of R was used for the normalization of gene and isoform expression, as well as the identification of differential expression genes (DEGs) and isoforms (DEIs) of CRC samples compared with normal samples. The enriched functions of DEGs and DEIs were obtained based on the Database for Annotation, Visualization and Integrated Discovery (DAVID). An independent dataset, GSE38832, was downloaded from the Gene Expression Omnibus (GEO) database for survival analysis of genes with sustained decreased/increased expression values at both gene and isoform levels with the development of CRC. RESULTS A total of 2301 genes and 4241 isoforms were found to be significantly differentially expressed in stage I-IV CRC samples. They are closely associated with muscle or cell system activity. Sixteen genes were screened out with sustained decreased/increased expression values at both gene and isoform levels with the development of CRC. Aberrant CBX8 and CD96 expressions were found to be significantly associated with CRC survival. CONCLUSIONS Through combined analysis of gene and isoform expression profiles, we identified several potential biomarkers that may play an important role in the development of CRC and could be helpful in its early diagnosis and treatment.

Abstract
Fibroblast activation protein-α (FAP-α) is a cell surface serine protease of the post-prolyl peptidase family, and stromal FAP-α expression may serve important functions in tumor occurrence and progression. In recent years, FAP-α expression in tumor cells has been detected in a number of types of tumor, and its roles in tumor growth and metastasis have been reported. However, the presence of FAP-α in colorectal cancer (CRC) cells lacks sufficient evidence and its role in angiogenesis remains unknown. The present study confirmed FAP-α expression in CRC cells at the tissue and cellular level, using immunohistochemistry and western blot analysis, respectively; it additionally identified that FAP-α in CRC cells was positively associated with vascular endothelial growth factor (VEGF)-A expression and microvessel density in stained tissue samples for the first time. In addition, western blotting identified that FAP-α overexpression in SW1116 cells significantly upregulated VEGF-A expression, and silencing of FAP-α in HT29 cells markedly inhibited VEGF-A expression. Survival analysis demonstrated that patients with high expression of FAP-α and VEGF-A had the shortest survival time. To detect the effects of FAP-α on human umbilical vein endothelial cells (HUVECs), conditioned medium (CM) from CRC cell lines was used and it was identified that CM from SW1116 cells with overexpressed FAP-α exhibited significantly increased VEGF-R2, phosphorylated extracellular signal-regulated kinase (p-ERK) and p-RAC-α serine/threonine-protein kinase (Akt) in HUVECs, in addition to the proliferation rate. Conversely, CM from HT29 cells with FAP-α silenced exhibited a significantly inhibited proliferation rate. Molecular mechanism analysis demonstrated that p-ERK and p-Akt in SW1116 and HT29 cells were affected by alterations in FAP-α expression, and treatment with a p-ERK inhibitor (U0126) and p-Akt inhibitor (LY294002) ameliorated VEGF-A upregulation induced by FAP-α overexpression. All the results confirmed the presence of FAP-α in CRC cells and suggested that FAP-α may effectively promote angiogenesis in CRC via the Akt and ERK signaling pathways.

Abstract
BACKGROUND Hemicolectomy is the treatment of choice for intestinal obstruction from right colon cancer. This review compares the laparoscopic vs open access in hemicolectomy for patients with right colon cancer. METHODS A systematic review and meta-analysis of clinical studies published after January 2017 was performed according to the Prisma guidelines. The study has been recorded on the Prospero register (CRD42016044108). RESULTS Five studies were included for review. Only one anastomotic leak was reported in conventional open anastomosis group (1.9%) and none of the studies included in the meta-analysis reported re-operations during the first 30 postoperative days. The 30-day postoperative mortality did not differ between the two groups. The length of incision, blood loss, early mobilization after surgery, the 30-day postoperative overall complication rate and hospital length of stay were significantly shorter in the laparoscopic group. The difference in the duration of procedure was statistically significant in favor of the open group. The number of dissected lymph nodes, the overall survival at 5 years and time to flatus were described only in one study, without any significant difference. Finally, none of the trials reported any information concerning differences in the costs between the two techniques. CONCLUSIONS The better outcomes described in this study achieved with laparoscopy, must be interpreted with caution because of the small number of patients involved, the selection and publication bias and the low level of evidence of the analysed trials. Indeed, the advantages of a minimally invasive approach, which have been demonstrated by the present meta-analysis, should encourage the use of laparoscopy also in emergency setting.
