“…The analysis of several studies have emphasized the importance of several clinical parameters such as age (Aslam et al, 2010), white blood cell, liver transaminases (Kemeny et al, 1983), haemoglobin (Graf et al, 1994), mean platelet volume (Tuncel et al, 2014), neutrophil/ lymphocyte ratio (Dirican et al, 2014;Wen-Zhuo et al, 2014), serum alkaline phosphatase (Chibaudel et al, 2003), serum γ-glutamyl transpeptidase (Wen-Zhuo et al, 2014), serum lactate dehydrogenase (Cetin et al, 2012), serum albumin (Tebbutt et al, 2003), tumor markers like CEA (Wen-Zhuo et al, 2014) and CA 19-9 (Katoh et al, 2008), ECOG PS (Galizia et al, 2008), primary tumor site (Bajwa et al, 2009), adjuvant chemotherapy (Katoh et al, 2008), pathological grade, number of metastatic sites (Yun et al, 2007), volume of liver metastases (Kleespies et al, 2009), metastasectomy (Settmacher et al, 2011) and state of KRAS/NRAS/BRAF mutation and PTEN loss (Tejpar et al, 2012;Yokota, 2012;Atreya et al, 2013) in the metastatic setting. Among these factors, patients with a V600E BRAF mutation have a poor prognosis which only settled in the guidelines (Bokemeyer et al, 2012).…”
