The structure and function of KRAS. 02. This study assessed the prognostic impact of specific Approximately 20% of all cancers harbor an activating RAS mutation, 75% of which are Kirsten rat sarcoma (KRAS) mutations. In our study group, we sought mutations in codons 12, 13, 61. Over the past 40 years, great efforts have been made to explore routes for indirect Colorectal cancer is the second most common malignancy worldwide and is characterized by specific somatic mutations including lesions in oncogenes, tumor suppressor genes, and DNA repair-related Introduction. Among all patients with KRAS G12C mutation, 77. 7%) and a lower one of c. Mutant KRAS is frequent in microsatellite stable right-sided CRC and is associated with poor Identifying patients who will experience lung cancer recurrence after surgery remains a challenge. See PAAD KRAS mutants page of the Spreadsheet. An analysis of a large patient population was The reported incidence of RAS (including KRAS and NRAS) mutations in colorectal cancer (CRC) is about 53% , while BRAF is mutated less frequently at a rate of 10% . Although the association between the RAS signaling and angiogenesis is well known, the negative predictive value of KRAS mutation has not been established in patients trea Colorectal cancer (CRC) is one of the most common malignant tumors in the digestive tract. Currently, the achievements obtained with covalent inhibitors of this variant have given the Mutation-activated Kras in cancer cells is a well-known challenging treatment-resistant factor that plays a critical role in treatment resistance. G12V and G12C mutations in the gene KRAS are associated with a poorer prognosis in primary colorectal cancer. 2% of the mutations; the remaining being in codon 13 KRAS mutation testing of tumours in adults with metastatic colorectal cancer Final scope January 2013 2 of 29 2. According to clinical and basic research data, patients with colorectal cancer exhibiting G12D and G12V KRAS mutations are resistant to anti-EGFR agents; however, this is not true of G13D and other minor mutations, which are still not well understood. 35G>T (p. G12C- and G12V-mutated KRAS cell lines have Activity of GDC-6036 Alone or in Combination in Participants with Advanced or In pancreatic adenocarcinoma, the KRAS-G12D mutation is associated with worse overall survival compared with wild-type KRAS, KRAS-G12R, or KRAS-G12V mutations [3, 4]. All KRAS mutations happen randomly and are somatic or non-hereditary mutations. However, in BRAF- and EGFR-mutated CRC, monotherapy will ultimately lead to the emergence of drug resistance due to adaptive KRAS G12V mutation circulating in plasma was detected in 9 of 10 colorectal cancer patients whose tumors were also mutated. A therapy targeting KRAS G12D mutation is also under development and promising efficacy is expected. We analyzed tumor samples, obtained from 394 of 572 patients (68. For the same group of patients, there is also Cohort 3, where it is combined with encorafenib (BRAF inhibitor) and cetuximab (EGFR inhibitor) for BRAF V600E mutated colorectal cancer. 2%), Kras G12V (21%), Kras G13D (20%) and Additionally, KRAS mutations in colorectal cancer lead to resistance to select treatment strategies. KRAS mutations occur in 45% of colorectal cancer (CRC) and is a key driver in CRC oncogenesis [1]. Although the G12V mutation is considered to be one of the most frequent KRAS codon 12 mutations in colorectal cancer patients—particularly in those with liver metastasis (ranging from 20. This mutation is often found in non-small cell lung cancer (NSCLC), colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC) and other cancers. In colorectal cancer (CRC) there is a clear survival advantage in KRAS wild-type compared with KRAS mutant in response to anti- Looking for metabolic-associated vulnerabilities is a promising approach for therapeutic intervention in KRAS-mutant colorectal cancer. The impact of KRAS mutations on the prognosis and survival of CRC patients drives many Evidence suggests the KRAS gene represents such a factor; its mutations are considered to be early indicators of CRC progression. For instance, the levels of taurine were reduced in cell lines with G13D and G12V mutations, whilst increased in cell lines harbouring G12D and G12R mutations. Here, the authors show that the RAS mutation spectrum is markedly different Conclusions. Keywords: colorectal cancer, KRAS mutation, targeted therapy. Human colorectal cancer Colorectal cancer is one of the world’s most prevalent and lethal cancers. Citation 2020; Zhu For example, in colorectal cancer, KRAS-G12D, the most common allele, and KRAS-G12V mutations have been linked to poor overall survival compared to wild-type (WT) KRAS cancers patients, while Background: This study sought to assess microsatellite and KRAS status, prevalence, and impact on outcome in stage IV colorectal cancer (CRC). 18 In pancreatic cancer, Yoon J, Koo K-H, Choi K-Y: MEK1/2 inhibitors AS703026 and AZD6244 may Be potential The new vaccine is able to activate immune cells that target different KRAS mutations called KRAS-G12D and KRAS-G12R, which drive about 90% of pancreatic cancers and 40% of colon cancers. There is a large spectrum of molecular aberrations with a lack of data regarding tumor side correlations and their impact on treatment response and overall survival. These KRAS G12V-specific T cells may help the body's immune system identify and kill KRAS G12V pancreatic, colorectal, and non-small cell lung cancers' tumor cells. KRAS is the most frequently mutated oncogene in human malignancies, observed in approximately two in five colorectal cancers (CRC). Colorectal cancer (CRC) is the third most common cause of cancer-related death worldwide with nearly one million deaths per year (). Specifically, we show that inhibitors of histone methyltransferase, EZH2, synergize with various rat sarcoma virus (RAS) pathway Which cancers are they linked to? KRAS mutations are present in approximately 25% of tumors, making them one of the most common gene mutations linked to cancer. One of the most exciting drug development areas against colorectal cancer is the targeting of undruggable kinases and kinase-substrate molecules, although Treatment-selected mutations, such as EGFR T790M in non-small-cell lung cancer, KRAS G12V in colorectal cancer, and BRAF V600E/ V600K in melanoma have been detected using ctDNA, thus paving way Background: KRAS is an oncogene that is mutated in about half of all metastatic colorectal cancers (mCRC). The most common KRAS mutations are G12V, G12D Abstract. 1 Dataset was obtained through the cBioPortal for Cancer Genomics. 10. Colorectal cancer (CRC) is a heterogeneous disease at the cellular and molecular levels. In this study, we investigated whether all KRAS mutations predict poor prognosis in patients with CRC. We aimed to evaluate whether mutant forms of epidermal growth factor receptor (EGFR) and Kirsten Keywords: KRAS, Mutations, Colorectal cancer, Metabonomics, Metabolomics, Metabolic profiling, NMR. A doctor may screen for KRAS mutations at the diagnosis stage. Additionally, in mice bearing CT-26 KRAS G12C tumor, AMG 510 also led to KRASG12C is the most commonly mutated variant of KRAS in non-small cell lung cancer. In colorectal cancer (CRC) there is a MUTATION RATES IN A POPULATION-BASED COHORT OF COLORECTAL CANCER. In the non-hypermutated CRC cohort, the prognostic risk of various RAS/BRAF allele mutations varied between local and metastatic CRC. Citation 1 Nearly half of the CRC patients exhibit KRAS mutations (MUT). Interestingly, patients with metastatic disease showed a The v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations are found in 35-45 % of colorectal cancer (CRC) cases. 27899. Among the CRCs with KRAS mutations, codon 12 mutations Cancer cells often develop genetic mutations that initiate and sustain the growth of tumors. 10 Previous comparisons between patients with KRAS wild-type tumors and those with KRAS mutations have not differentiated between the mutational subtypes. KRAS mutation is a significant driving factor of tumor, and KRAS G12V mutation has the highest incidence in solid tumors such as pancreatic cancer and colorectal cancer. Introduction. Moreover, KRAS-G12D and KRAS-G12V remain the most common mutations in CRC and are found in the largest patient populations 4. Subsequently, the association between KRAS mutant variants and treatment survival in NSCLC has also been extensively studied (23, 76, 77). 38G>A (p. 1 This corresponds to over 2. 1 Purpose of the medical technology KRAS mutation testing is indicated in adults with metastatic colorectal cancer, where metastases are confined to the liver and are unresectable. G12V) mutations (32. Avutometinib is a novel small molecule RAF/MEK clamp. In colorectal cancer (CRC) there is a clear survival advantage in KRAS wild-type compared with KRAS mutant in response to anti-epidermal growth factor receptor (EGFR) therapies [5 Although the G12V mutation is considered to be one of the most frequent KRAS codon 12 mutations in colorectal cancer patients—particularly in those with liver metastasis (ranging from 20. Numerous targeted agents that are successfully marketed have demonstrated both efficacy and tolerability [28, 29]. 821-828, 10. The KRAS oncogene is mutated in approximately 35%-45% of colorectal cancers, and KRAS mutational status testing has been highlighted in recent years. G12A (101, 4. The most frequently mutated of these oncogenic driver genes, called KRAS, is associated with some of the most fatal cancer The KRAS gene is mutated in approximately 40% of CRCs, the most frequent mutations occurring at codons 12 (G12D, 13%; G12V, 9%) or 13 (G13D, 8%). Therefore, we included 3829 patients with resected lung adenocarcinoma from 2008 to 2020 and showed that the KRAS G12V mutation was more frequent in male patients, former/current smokers, patients with radiologic solid nodules We transduced the library into an isogenic model system based on the colorectal cancer cell line CaCo2, harboring a conditional mutant KRAS G12V transgene. According to the 2024 cancer statistics, the incidence and mortality rates of colorectal cancer (CRC) are gradually increasing. These studies shed light on the significance of KRAS G12V mutation in cancer development as well as future therapy. Citation 2, Citation 3 KRAS mutations lead to the continuous activation of the RAS, thereby promoting the proliferation, metastasis, and drug Non-small Cell Lung Cancer (NSCLC) KRAS mutations, mainly KRAS G12C, G12D, and G12V, are observed in 20–30% of NSCLC patients, predominantly in patients with adenocarcinomas (2, 76). . According to The Cancer Genome Atlas (TCGA) database, APC, TP53, KRAS, and SMAD4 are the four most frequently mutated Current treatments for KRAS-mutant colorectal cancers are often limited by cellular plasticity and rewiring responses. G12D is the most common KRAS mutation in colorectal cancer, followed by G12V and G13D. 2014. Intrinsic resistance to MEK inhibition in KRAS mutant lung and colon cancer through transcriptional induction of ERBB3. Colorectal cancer patients had 35. KRAS mutations constitute approximately 40% of all CRC cases, making it a common oncogene mutation in CRC patients (Dienstmann et al. See figures 1A-1C in Figures. 8 million annual KRAS-mutant cancer diagnoses In preclinical models, AMG 510 was able to induce KRAS G12C-mutant colorectal cancer patient-derived xenograft (CRC PDX) shrinkage. 106P efficacy and safety of IBI351 (GFH925) monotherapy in metastatic colorectal cancer harboring KRAS G12C mutation: updated results from a pooled analysis of two phase I studies As a therapeutic class, TCRs have been developed targeting KRAS G12V 16,17 and KRAS G12D. A) Frequencies of KRAS alterations in mCRC at Memorial Sloan Kettering Cancer Center. The study is for patients whose cancer has spread through the body and for whom previous treatments were not KRAS G12C mutant colorectal cancer Okada Y, Ono K, Shimada R, et al. Mutations of the KRAS gene occur in ~40% of metastatic colorectal cancers. KRAS drives 32% of lung cancers, 40% of colorectal cancers, and 85% to 90% of pancreatic cancer cases. 001) and for high PD-L1 expression (44% vs 38% for We used four KRAS G12-mutated (SNS26: KRAS G12S; TUM10: KRAS G12V; TUM3: KRAS G12A; TUM52: KRAS G12C) and three KRAS WT (TUM42, TUM50, TUM65) PDOs (Supplementary Table 9). There are many different types of RAS mutations, the most frequent being G12V Abstract Simple Summary. Targeting KRAS mutations with drugs is challenging because KRAS is considered undruggable due to the lack of classic drug binding sites. Current knowledge regarding the KRAS G12C inhibitor debunks the notion that the KRAS oncogene is ‘undruggable’. Tumor mutation . Previous studies had reported that KRAS G12V-reactive CodeBreaK100 is an ongoing phase 1–2 basket trial evaluating monotherapy with sotorasib in patients with solid tumours harbouring the KRAS G12C mutation. Of the therapies with KRAS G12V as a Using whole-genome analysis of 37 patients with metastatic colorectal cancer (mCRC) treated with the chemotherapy trifluridine/tipiracil (FTD/TPI), we identified KRAS KRAS mutations are one of most dominant mutations in colorectal cancer (CRC). The success of finding allele-specific covalent KRASG12C inhibitors recently has Here, we report that KRAS G12V is a good neoantigen candidate for people with the HLA-A*11:01 type, and combined therapy with a single neoantigen mRNA vaccine targeting KRAS G12V and the PD-1 The mutation in the KRAS gene is a vital genetic factor that can influence treatment for colon cancer. The combination of encorafenib + cetuximab is FDA approved for BRAF-mutated colorectal cancer. KRAS G13D mutation tended to be the only prognostic marker for stages I–III CRC; however, KRAS G13D/G12V/G12C mutations collectively defined a high-risk subgroup of mCRC patients with poor prognosis, who would RAS mutations are among the most common oncogenic mutations in human cancers. 8%) [21,27]—the number of KRAS G12V-mutated samples in our population of study at La Paz University Hospital was very low (13 out of 554 total KRAS mutations were identified in 30. Mutations in codon 12 were accounted for 77. G13D) mutations (12. While this cohort has historically been difficult to manage, the last The US Food and Drug Administration has granted accelerated approval for the targeted therapy adagrasib (Krazati ®) in combination with the drug cetuximab (Erbitux ®) for people with advanced colorectal cancer caused Introduction: The high frequency of RAS mutations, particularly KRAS mutations, in colorectal cancer (CRC) and the ineffectiveness of anti-EGFR antibodies in treating this disease has created a significant unmet medical need, especially for treating patients in the metastatic phase of this disease. 8%) [21,27]—the number of KRAS G12V-mutated samples in our population of study at La Paz University Hospital was very low (13 out of 554 total Abstract. Strategies targeting the oncogenic KRAS pathway include direct and AbstractKirsten Rat Sarcoma (KRAS) gene somatic point mutations is one of the most prominently mutated proto-oncogenes known to date, and accounts for approximately 60% of all colorectal cancer cases. celrep. Approximately half of metastatic CRCs harbor KRAS (Kirsten Rat Sarcoma In pancreatic adenocarcinoma, the KRAS-G12D mutation is associated with worse overall survival compared with wild-type KRAS, KRAS-G12R, or KRAS-G12V mutations [3,4]. KRAS mutation rates are different among CRC patients belonging to different there is a higher prevalence of c. Recently, a novel therapy targeting KRAS G12C mutation has demonstrated promising efficacy for advanced solid tumors, including mCRC. 9 cases when KRAS was Frequency and clinical associations reported for KRAS alterations in metastatic colorectal cancer (mCRC). Except for the proven predictive significance of KRAS mutations in CRC patients, their prognostic significance is still under evaluation. Interestingly, KRAS G12C and G12V arise from C→A mutations, reflecting the mutation signature associated with tobacco exposure Hobor S, Bertotti A, et al. Furthermore, in a KRAS mutations are one of the most common genetic abnormalities in cancer, especially lung, colon, and pancreatic cancers. In this article, we focus on the therapeutic strategies targeting KRAS- mutant CRC, while reviewing and elaborating on the discovery and physiology of KRAS. The most common point mutation in KRAS involves an amino acid substitution at codons 12 or 13 (G12D, G12V and G13D) in exon 2, but codons 59 and 61 in exon 3 and codons 117 and 146 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) is the most frequently mutated oncogene, occurring in a variety of tumor types. Our study There is a growing unmet need for a personalized therapy approach for patients with KRAS-mutant colorectal cancer. 6% (n = 86) of patients in the discovery cohort and 37. 5% to 32. b The distribution of KRAS allele frequencies at the four hotspots, codons 12 (left), 13 (middle-left), 61 (middle-right), and 146 (right) in each Introduction. Here, the authors show that the cholesterol-uptake regulator Background Genes in the Ras pathway have somatic mutations in at least 60 % of colorectal cancers. 99%), which is comparable with the previously pub-lished data. 3% (n = 79) of patients in the validation cohort. Therefore, we utilized three drug sensitivity prediction resources and further filtering with molecular The most frequent KRAS mutants in the three sets of PDAC data are the same, G12D > G12V > G12R >Q61H. 045 Abstract. 1016/j.

Overall (d), the most frequently diagnosed KRAS mutational subtype in LADC patients is KRAS G12C, followed by KRAS G12V, KRAS This study is open to adult patients with solid tumors who have a KRAS G12V mutation. 62 copies of mutated KRAS/mL plasma, whereas in healthy controls only residual copies were found (0. et al. The most frequent mutations in this gene, point substitutions in codons 12 and 13, were validated as negative predictors of response to anti-epidermal growth factor receptor antibodies. This approach revealed that suppression The response in KRAS G12C mutated colorectal cancer is notably inferior, with an ORR of just 9. KRAS mutations were historically considered “undruggable” ten years ago and associated with resistance to EGFR targeted therapy. Kirsten rat sarcoma viral oncogene homolog (KRAS)-mutated colorectal cancer (CRC) seems to have a different biological behavior and therapeutic approach compared with non-KRAS mutated CRC. 1) Reduction in ctDNA was not seen in patients with KRAS G12D or KRAS G12V mutated tumors, therefore its potency as a single agent in pancreas cancer is uncertain . The Russian CRC patients find out a higher frequency of mutations G12V and a lower frequency of mutations G13D, than patients from Europe and it should be taken into account The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize KRAS G12V, a protein on the surface of tumor cells. Patients received onvansertib (15 mg/m 2 once daily Three studies delineating the prevalence of KRAS mutations in gastrointestinal and colorectal cancer, with specific focus on the KRAS G12C mutation, and an evaluation of patient outcomes according to the mutation status were presented at the ESMO World Congress on Gastrointestinal Cancer 2021 (30 June - 3 July). 60% (80/354) were female. The most frequent mutation in codon 12 was G12V and G12D, and in codon 13 - G13D . a The frequency of KRAS mutations in each cancer. , 69 (5) KRAS G12V mutation is an adverse prognostic factor of Chinese gastric cancer patients[J] J. Kirsten rat sarcoma (KRAS) is a commonly mutated oncogene in CRC, with mutations in approximately 40% of all CRC cases; its mutations result in constitutive activation of the KRAS protein, which acts as a molecular switch to persistently stimulate downstream signaling Activating oncogenic mutations in KRAS and NRAS are common in colorectal cancer, which is a heterogenous disease. Int J Colorectal Dis Colorectal cancers without KRAS and PIK3CA mutations represent the most prevalent group (48–58 % of patients) and present therapeutic targeted opportunities with BRAF inhibitors and immune checkpoint inhibitors in the subsets with BRAF mutations (15–22 %) and Microsatellite Instability (MSI, 14–16 %), respectively. Here, using a cell-surface proteomics approach, KRAS-mutated colorectal cancer cells are shown to express high Mutation-activated Kras in cancer cells is a well-known challenging treatment-resistant factor that plays a critical role in treatment resistance. 62 copies/mL, p = 0. Introduction In non-Sq NSCLC, KRAS G12C mutated tumors were enriched for high TMB ≥ 10 mutations/Mb (40% vs 33% vs 32% for KRAS non-G12C and WT, both p < 0. 7% (95% CI 3. The The G12V mutation of KRAS in lung adenocarcinoma is shown as a separate line because that particular amino acid change satisfies Test 3 (>10% of the samples with mutant KRAS contain the KRAS G12V mutation and this is >4x the number when KRAS is wild-type (0)). 0066). Cell Rep 2014;7:86-93. 1. Among RAS mutations, KRAS has the highest frequency and is present in almost 30% of non-small-cell lung cancer (NSCLC) patients. 33%) followed by colorectal cancer (1. 12 In pancreatic cancer models, MRTX1133 has also been shown to work synergistically with immunotherapy, and this approach Koo K-H, Choi K-Y: MEK1/2 inhibitors AS703026 and AZD6244 may Be potential therapies for KRAS mutated colorectal cancer that is resistant to EGFR monoclonal antibody therapy. The study was conducted Approximately 40-45 percent of colorectal cancer patients have a KRAS mutation in their tumor. Citation 2015; Shayimu et al. According to clinical and basic research data, patients with colorectal cancer exhibiting G12D and G12V KRAS mutations are KRAS mutational subtypes and smoking history in lung adenocarcinoma (LADC) []. The second most prevalent sub-set, with In NSCLC, the prevalence of KRAS mutation is about 30–35 % [6], [7] and is almost exclusively detected in adenocarcinoma, while is rare in squamous cell carcinoma. a According to homology, KRAS, which consists of 188/189 amino acids can be divided into three parts. The mutation of Kirsten rat sarcoma viral oncogene homolog (KRAS) has been reported to be prognostically important in patients with colorectal cancer (CRC). For example, ten different missense mutants of KRAS were found in the TCGA colon Although the G12V mutation is considered to be one of the most frequent KRAS codon 12 mutations in colorectal cancer patients—particularly in those with liver metastasis (ranging from 20. Clinical efficacy has been documented with TNO155, a pyrazine Yuan, Y. They are frequent drivers in lung, colorectal and pancreatic cancers. Prevalence of microsatellite status (microsatellite instability-high [MSI-H] or microsatellite PIK3CA mutations in colorectal cancer are associated with clinical resistance to EGFR-targeted monoclonal antibodies[J] Cancer Res. Here we describe a promising therapeutic strategy that simultaneously targets epigenetic and oncogenic signals. Approved treatments for advanced KRAS mt NSCLC (excluding G12C) are limited to chemotherapy and immune checkpoint inhibitors (ICIs). the KRAS-G12D mutation is associated with worse overall survival compared with wild-type KRAS, KRAS-G12R, or KRAS-G12V mutations [3,4]. Mutation of Kirsten Rat Sarcoma Viral Oncogene (KRAS), a member of RAS genes (HRAS, KRAS, and NRAS) that are frequently mutated in Background: Activating mutations in the MAPK pathway are predictive biomarkers in mCCR and 50% of patients (pts) present KRAS mutations. 6–19. Human colorectal cancer (CRC) has four major Kras mutations; Kras G12D (34. 7150/jca. 9%) with colorectal cancer who were randomly assigned to receive cetuximab plus best supportive care or best supportive care KRAS G12V is a predictive biomarker for use of afatinib, dacomitinib, erlotinib, gefitinib, osimertinib, cetuximab, and panitumumab in patients. In current (a) and former (b) smokers, KRAS G12C is the most common mutation, while KRAS G12D is the most frequent mutation among never smokers (c). 40% (274/354) of the patients were male and 22. The first part consisting of the first 85 amino acid residues is a highly conserved region. Thus, KRAS G12V neoantigen-specific TCR-engineered T cells could be a promising cancer treatment approach for pancreatic cancer. Despite activating the same pathway, the BRAF V600E mutation and the prevalent mutations in codon 12 and 13 of KRAS have all been linked to different clinical outcomes, but the molecular mechanisms behind these differences largely remain to be For KRAS G12V tumors, this analysis to determine whether ctKRAS variant-specific associations exist in other solid tumors such as lung and colorectal cancer where KRAS mutations are KRAS mutations in patients with metastatic colorectal cancer (CRC) are a negative marker of the effectiveness of anti-EGFR therapy and have prognostic significance. In our cohort, the highest KRAS G12C mutation frequency tumor type was lung cancer (12. Over 80 % of KRAS mutations occur in codon 12, with the most common mutations being KRAS G12C (substitution of glycine to cysteine; approximately 40 %), KRAS G12V (substitution of Introduction. B) KRAS mutations are more frequent in microsatellite stable (MSS) CRC as compared to microsatellite instability This multicenter, open-label, single-arm study enrolled patients with KRAS-mutated mCRC previously treated with oxaliplatin and fluorouracil with or without bevacizumab. The Kirsten rat sarcoma virus (KRAS) gene is the most commonly mutated oncogene in cancer, and its activation promotes tumor proliferation and survival. KRAS G13D and G12C also had higher intracellular concentrations of Background: KRAS mutations (mt) occur in ~30% of lung adenocarcinomas, among which G12C is most common (40%), followed by G12V (22%) and G12D (16%). In phase 1 part, 129 patients were included and 42 patients with metastatic colorectal cancer had a response rate of 7% (95% CI 1·50–19·48) and a median progression-free survival of 4·0 months. Citation 2021). The vaccine contains synthesized peptides (short chains of amino acids) that can launch immune cells to target cancer cells with these mutations. Loss of genomic integrity facilitates the accumulation of multiple mutations during the development of CRCs [1], [2], [3], [4]. Colorectal cancer is the second most common malignancy worldwide and is characterized by specific somatic mutations including lesions in oncogenes, tumor suppressor genes, and DNA repair-related genes 1, 2. 5%) in comparison with patients from other parts of Europe. A KRAS mutation is not hereditary (a germline mutation) and will not be passed from one generation to another in a family. Our analysis of characteristics of KRAS mutations revealed the mutation rate for codon 12 was Colorectal cancer with a Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) gene mutation is considered to be resistant to anti‑EGFR agents. 3 In The A conversion of the amino acid glycine (G) to aspartic acid (D) at this site, hereafter referred to as KRAS G12D, is the most frequent KRAS mutant in human gastrointestinal cancers and has been Keywords: Colorectal cancer, KRAS mutation, Proteogenomics, Molecular subtype, Prognosis.
