Abstract
BACKGROUND In addition to discontinuing treatment at disease progression, cumulative toxicity limitations and genetic mutations play important roles in chemotherapy choice in metastatic colorectal cancer (mCRC). However, in recent years, targeted therapies, such as immune checkpoint inhibitors or monoclonal antibodies (MoAbs), have been used with chemotherapy to improve clinical outcomes in patients with mCRC. AREAS OF UNCERTAINTY Approximately 15% of patients with CRC would be eligible for further targeted therapy with immune checkpoint inhibitors based on genetic testing, but most patients with CRC would not qualify, especially Kirsten rat sarcoma wild-type. Therefore, adding MoAb is only an option for most patients until disease progression or unacceptable toxicity occurs. However, the results are not consistent with the combination of MoAb and different chemotherapy bases. In addition, most results from combining MoAb with different chemotherapy bases are not consistent. DATA SOURCES This meta-analysis includes published of the PubMed and Embase databases, limited to English literature, and patients were treated with MoAb combination. Randomized control trials conducted published up to May 2021 were considered for inclusion. THERAPEUTIC ADVANCES Fluoropyrimidine-based chemotherapy has been the backbone of palliative therapy for mCRC, with demonstrated benefits. This article will review the efficacy and safety of randomized control trials comparing different MoAb with fluoropyrimidine-based chemotherapy as first-line therapy for patients with mCRC, particularly in Kirsten rat sarcoma wild-type. CONCLUSION This meta-analysis revealed that MoAb plus chemotherapy has better progression-free survival and objective response rate than chemotherapy alone. However, treatment-related serious adverse events (grade ≥ 3) should be considered, particularly severe rash, diarrhea, and hypertension.

Abstract
The morbidity of colorectal cancer (CRC) has risen to third place among malignant tumors worldwide. In addition, CRC is a common cancer in China whose incidence increases annually. Angiogenesis plays an important role in the development of tumors because it can bring the nutrients that cancer cells need and take away metabolic waste. Various mechanisms are involved in the formation of neovascularization, and vascular endothelial growth factor is a key mediator. Meanwhile, angiogenesis inhibitors and drug resistance (DR) are challenges to consider when formulating treatment strategies for patients with different conditions. Thus, this review will discuss the molecules, signaling pathways, microenvironment, treatment, and DR of angiogenesis in CRC.

Abstract
The vasculature is a key player and regulatory component in the multicellular microenvironment of solid tumors and, consequently, a therapeutic target. In colorectal carcinoma (CRC), antiangiogenic treatment was approved almost 20 years ago, but there are still no valid predictors of response. In addition, treatment resistance has become a problem. Vascular heterogeneity and plasticity due to species-, organ-, and milieu-dependent phenotypic and functional differences of blood vascular cells reduced the hope of being able to apply a standard approach of antiangiogenic therapy to all patients. In addition, the pathological vasculature in CRC is characterized by heterogeneous perfusion, impaired barrier function, immunosuppressive endothelial cell anergy, and metabolic competition-induced microenvironmental stress. Only recently, angiocrine proteins have been identified that are specifically released from vascular cells and can regulate tumor initiation and progression in an autocrine and paracrine manner. In this review, we summarize the history and current strategies for applying antiangiogenic treatment and discuss the associated challenges and opportunities, including normalizing the tumor vasculature, modulating milieu-dependent vascular heterogeneity, and targeting functions of angiocrine proteins. These new strategies could open perspectives for future vascular-targeted and patient-tailored therapy selection in CRC.

Abstract
OBJECTIVE To evaluate the benefit of bevacizumab under the comprehensive treatment strategy and its advantages over other drugs, so as to provide reference for the formulation of clinical plans. METHODS As of October 1, 2022, the randomized controlled clinical trials of bevacizumab in combination with metastatic colorectal cancer published in PubMed, Cochrane Library and Medline databases were searched. The odds ratio (OR) and its 95% confidence interval (CI) were used to evaluate the short-term disease control effect and long-term survival of the treatment strategy. RESULTS 21 RCTs (6665 patients; 3356 patients in the experimental group and 3309 patients in the control group; average age, 55-75 years) were treated with bevacizumab as the experimental group for metastatic colorectal cancer. BEV has stronger anti-tumor activity than the single treatment scheme (OR = 1.30, 95% CI: 1.11-1.52). And Benefits of the BEV group were 0.73 (0.55, 0.96), 1.26 (0.71, 2.24), 1.63 (0.92, 2.87) and 0.07 (0.02, 0.25) compared with CET, VAN, CED and PAN respectively. The disease control of BEV combined therapy was better (OR = 1.36, 95% CI: 1.04-1.78). The same as compared with cediranib (OR = 1.94, 95% CI: 1.06-3.55). However, the long-term prognosis of BEV, including the overall survival (HRs = 0.98, 95% CI: 0.84-1.15) and progression-free survival (HRs = 1.05,95% CI: 0.97-1.13) were not prolonged. The survival benefits of cetuximab and panitumumab were not reflected. CONCLUSION The addition of BEV can enhance the anti-tumor ability and disease control, while cetuximab and panitumumab may have stronger ability. However, it did not effectively improve the survival of patients. A more reasonable and effective treatment plan needs more clinical experimental support.

Baseline and Longitudinal Neutrophil-to-Lymphocyte Ratio as Prognostic Factor for Metastatic Colorectal Cancer: A Secondary Analysis of the ITACa Randomized Trial. JCO Precis Oncol 2024; 8:e2300256. [PMID: 38295317 PMCID: PMC10843252 DOI: 10.1200/po.23.00256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 10/16/2023] [Accepted: 11/16/2023] [Indexed: 02/02/2024] Open
Abstract
PURPOSE We aimed to investigate the prognostic role of baseline and longitudinal levels of neutrophil-to-lymphocyte ratio (NLR) in patients with metastatic colorectal cancer (mCRC) treated with chemotherapy + bevacizumab (CT + B) or chemotherapy only. Additionally, we investigated whether treatment outcomes were mediated by the longitudinal biomarker. METHODS Data from an Italian randomized phase III trial were used. The main end point was progression-free survival (PFS). To address research questions, a series of joint models of longitudinal and survival data were specified, and the direct and indirect treatment effects were quantified. RESULTS Data for 239 patients, 113 (47.3%) treated with CT + B and 126 (52.7%) with CT only, were included in the analyses. The effect of NLR seemed to be mediated by the longitudinal trajectory of the biomarker. Only in the patient subgroup treated with CT + B, the baseline NLR retained a direct effect on PFS. Regarding the effect of treatment on PFS, two scenarios were observed. In the subgroup of patients with low baseline, NLR bevacizumab showed a direct protective effect only (hazard ratio [HR], 0.66 [95% CI, 0.45 to 0.98]), whereas in the subgroup with high baseline NLR, there was evidence for an adverse direct effect (HR, 1.63 [95% CI, 1.03 to 2.57]) and a protective indirect-which is mediated by the longitudinal biomarker-effect (HR, 0.71 [95% CI, 0.55 to 0.90]). CONCLUSION In our study, inflammatory indexes collected longitudinally showed a significant adverse prognostic role, thus suggesting the collection and use of such data for better clinical decision making. In the specific setting, we considered this is particularly important as the treatment effect seemed to be modified by both the baseline and longitudinal inflammation statuses. However, further research is needed to understand the possible factors underlying these results.

Abstract
Background Validated predictors of sensitivity or resistance to Bevacizumab (Bev) are not available, and Inflammatory Indexes (IIs) has been reported to be useful prognostic factors in various malignant solid tumours, including metastatic colorectal cancer (mCRC). Objectives To explore the prognostic value of IIs in mCRC patients treated with first-line chemotherapy plus Bev. Design One hundred and eighty-two patients diagnosed with mCRC and treated with first line chemotherapy plus Bev were considered for this prospective non-pharmacological study. Neutrophil, lymphocyte, platelet, aspartate transaminase (AST) and lactate dehydrogenase (LDH) tests were carried out at baseline and before each treatment cycle, according to clinical practice. Methods Pre-treatment Systemic Immune-inflammation Index (SII), Colon Inflammatory Index (CII) and Aspartate aminotransferase-Lymphocyte Ratio Index (ALRI) were evaluated to assess a correlation with progression-free survival (PFS) and overall survival (OS). Results In the overall population, PFS and OS were lower in patients with high SII (HR 1.64, p = 0.006 and HR 1.75, p = 0.004, respectively) and high ALRI (HR 2.13, p = 0.001 and HR 1.76, p = 0.02, respectively), but no difference was detected according to CII value. The multivariate analysis confirmed both SII and ALRI as independent prognostic factors for PFS (HR 1.64 and 2.82, respectively) and OS (HR 1.65 and 2.12, respectively). Conclusion Our results demonstrate and confirm that IIs, and in particular SII and ALRI, are easy to measure prognostic markers for patient candidates to first line chemotherapy plus Bev for mCRC.

Abstract
BACKGROUND Guidelines show that for metastatic colorectal cancer (mCRC), a combination of three-drug regimens, fluorouracil, leucovorin, and oxaliplatin and bevacizumab (BVZ), is one of the first-line standard therapies. BVZ is generally well tolerated; however, it is associated with infrequent, life-threatening side effects such as severe hypertension (HTN) (5%-18%), Grade ≥3 arterial thromboembolism (ATE) (2.6%), Grade ≥3 hemorrhagic events (1.2%-4.6%), and gastrointestinal perforation (0.3%-2.4%). This meta-analysis aims to evaluate the additive risk of BVZ-induced severe HTN and thromboembolism when BVZ is combined with a standard chemotherapy regime in patients with mCRC. METHODS Our search was conducted from January 29, 2022, to February 22, 2022, through databases of PubMed, clinicaltrial.gov, EMBASE, Web of Science, and Cochrane Library. Data analysis from randomized controlled trials (RCTs) and clinical trials was conducted using Review Manager V.5.4, comparing BVZ-chemotherapy to chemotherapy only, focusing on cardiovascular AE such as HTN and arterial and venous thromboembolism. RESULTS The analysis from 26 clinical trials and RCTs showed that the odds of HTN were about four times higher, and ATE subgroup analysis of 11 studies showed over two times higher odds of ATE in patients being treated with BVZ compared to the chemotherapy-only group. CONCLUSION BVZ, when added to the standard chemotherapy regimen for mCRC, was associated with higher odds of developing HTN and thromboembolism, specifically ATE, than the chemotherapy-only group. Our findings are significant as they provide vital information in analyzing the risk-benefit ratio of adding BVZ to the standard chemotherapy regime in patients with mCRC, especially in patients with vascular comorbidities.

Abstract
The synthesis and biochemical activity of a series of chiral trans 3-hydroxyl β-lactams targeting tubulin is described. Synthesis of the series of enantiopure β-lactams was achieved using chiral derivatising reagent N-Boc-l-proline. The absolute configuration was determined as 3S,4S for (+) enantiomer 4EN1 and 3R,4R for (-) enantiomer 4EN2. Antiproliferative studies identified chiral 3S,4S b-lactams with subnanomolar IC50 values across a range of cancer cell lines, improving potency with respect to the corresponding racemates. Fluoro-substituted (+)-(3S,4S)-4-(3-fluoro-4-methoxyphenyl)-3-hydroxy-1-(3,4,5-trimethoxyphenyl)azetidin-2-one (27EN1) was determined as the lead eutomer with dual antiproliferative activity in triple negative breast cancer cells (TNBC), and combretastatin A-4 resistant HT-29 colorectal cancer cells. IC50 values were in the range of 0.26-0.7 nM across four cell lines. Tubulin polymerisation assays, confocal microscopy and molecular modelling studies indicated that 3S,4S eutomers are microtubule destabilisers, while 3R,4R distomers have lower potency as microtubule destabilisers. 27EN1 demonstrated anti-mitotic and pro-apoptotic activity in MDA-MB-231 and HT-29 cells in addition to selective toxicity toward MCF-7 breast cancer versus non-tumorigenic MCF-10-2A cells. The related 3S,4S β-lactam eutomer 4EN1 downregulated expression of key cell survival anti-apoptotic proteins Bcl-2 and Mcl-1 in MDA-MB-231 cells while 27EN1 downregulated Mcl-1 in HT-29 cells. Chiral β-lactam 27EN1 will be further developed for treatment of TNBC and CA-4 resistant colorectal cancers.

Abstract
BACKGROUND AND AIMS Chemotherapy (CTx) with targeted therapy (TT) have increased the overall response rate (ORR) and improved survival in unresectable or borderline resectable metastatic colorectal cancer (mCRC). However, the resection rate is an endpoint with often suboptimal expert involvement. The aim was to investigate whether the improvements in ORR have translated to improved resection rates (RR). STUDY DESIGN A systematic literature search was performed using the PICO process. STATISTICAL ANALYSIS Odds ratios, and 95% confidence intervals (OR, 95% CI) were analyzed for ORR and RR using dichotomous values with the Mantel-Haenszel method. Progression-free survival (PFS) and overall survival (OS) were analyzed using the inverse-variance method and displayed as hazard ratios and 95% confidence intervals (HR, 95% CI). RESULTS The literature search returned 469 records. Sixteen articles with 5724 patients were selected for analysis. The qualitative analysis revealed low and moderate risk of bias endpoints. Higher ORR was observed with CTx + TT versus CTx only (OR: 0.62 [95% CI 0.45; 0.82], p = 0.002) and with triplet CTx + TT versus doublet CTx + TT (OR: 0.61 [95% CI 0.46; 0.81], p < 0.001). PFS and OS were improved by use of TT (HR: 0.68-0.84; p < 0.001 to 0.04). The overall RR was low (< 15%) and did not improve in the same way as the other endpoints. CONCLUSION The ORR and survival rates in unresectable and borderline resectable mCRC were improved by modern CTx and TT that did not translate into higher RR, mostly due to the lack of expert involvement.

Abstract
As one of the main threats to human life (the fourth most dangerous and prevalent cancer), colorectal cancer affects many people yearly, decreases patients' quality of life, and causes irreparable financial and social damages. In addition, this type of cancer can metastasize and involve the liver in advanced stages. However, current treatments can't completely eradicate this disease. Chemotherapy and subsequent surgery can be mentioned among the current main treatments for this disease. Chemotherapy has many side effects, and regarding the treatment of this type of tumor, chemotherapy can lead to liver damage, such as steatohepatitis, steatosis, and sinus damage. These damages can eventually lead to liver failure and loss of its functions. Therefore, it seems that other treatments can be used in addition to chemotherapy to increase its efficiency and reduce its side effects. Biological therapies and immunotherapy are one of the leading suggestions for combined treatment. Antibodies (immune checkpoint blockers) and cell therapy (DC and CAR-T cells) are among the immune system-based treatments used to treat tumors. Immunotherapy targets various aspects of the tumor that may lead to 1) the recruitment of immune cells, 2) increasing the immunogenicity of tumor cells, and 3) leading to the elimination of inhibitory mechanisms established by the tumor. Therefore, immunotherapy can be used as a complementary treatment along with chemotherapy. This review will discuss different chemotherapy and immunotherapy methods for colorectal cancer. Then we will talk about the studies that have dealt with combined treatment.

Abstract
PURPOSE Plasma circulating tumor DNA (ctDNA) is a valuable resource for tumor characterization and for monitoring of residual disease during treatment; however, it is not yet introduced in metastatic colorectal cancer (mCRC) routine clinical practice. In this retrospective exploratory study, we evaluated the role of ctDNA in patients with mCRC treated with chemotherapy plus bevacizumab. MATERIALS AND METHODS Fifty-three patients were characterized for RAS and BRAF status on tumor tissue before the start of treatment. Plasma was collected at baseline, at first clinical evaluation, and at disease progression. ctDNA analysis was performed using Oncomine Colon cfDNA Assay on the Ion S5 XL instrument. RESULTS At baseline, from a plasma sample, RAS, BRAF, or PIK3CA mutations were detected in 44 patients. A high correspondence was observed between ctDNA and tumor tissue mutations (KRAS 100%, NRAS 97.9%, BRAF 97.9%, PIK3CA 90%). Low baseline variant allele frequency (VAF) was found to be associated with longer median progression-free survival (PFS) compared with those with high VAF (15.9 v 12.2 months, P = .02). A higher PFS {12.29 months (95% CI, 9.03 to 17.9) v 8.15 months (95% CI, 2.76 to not available [NA]), P = .04} and overall survival (34.1 months [95% CI, 21.68 to NA] v 11.1 months [95% CI, 3.71 to NA], P = .003) were observed in patients with large decline in VAF at first evaluation. CONCLUSION ctDNA analysis is useful for molecular characterization and tumor response monitoring in patients with mCRC. Quantitative variations of released ctDNA are associated with clinical outcomes.

Int J Colorectal Dis 2023; 38:164. [PMID: 37289304 DOI: 10.1007/s00384-023-04442-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 05/21/2023] [Indexed: 06/09/2023]
Abstract
OBJECTIVE The aim of the present study was to explore the incremental benefit of bevacizumab (Bev) in the treatment of advanced colorectal cancer (CRC) with different doses. METHODS A literature search of eight electronic databases (China National Knowledge Infrastructure, Wanfang databases, Chinese Biomedical Database, VIP medicine information, Cochrane Library, MEDLINE, PubMed, and EMBASE) was conducted from database creation to December 2022. Randomized controlled trials (RCTs) that compared Bev at various dosages + chemotherapy (CT) versus placebo (or blank control) + CT were selected. The overall survival (OS), progression-free survival (PFS), overall response rate (ORR; complete response [CR] + partial response [PR]), and grade ≥ 3 adverse events (AEs) were integrated first by pooled analysis. The likelihood of ideal dosage of Bev was then ranked using random effects within Bayesian analysis. RESULTS Twenty-six RCTs involving 18,261 patients met the inclusion criteria. OS increased significantly after using 5 mg (HR: 0.87, 95% CI 0.75 to 1.00) and 10 mg dosages of Bev (HR: 0.75, 95% CI 0.66 to 0.85) with CT, but statistical significance was not attained for the 7.5 mg dose (HR: 0.95, 95% CI 0.83 to 1.08). A significantly increased in PFS with doses of 5 mg (HR: 0.69, 95% CI 0.58 to 0.83), 7.5 mg (HR: 0.81, 95% CI 0.66 to 1.00), and 10 mg (HR: 0.60, 95% CI 0.53 to 0.68). ORR distinctly increased after 5 mg (RR: 1.34, 95% CI 1.15 to 1.55), 7.5 mg (RR: 1.25, 95% CI 1.05 to 1.50), and10 mg (RR: 2.27, 95% CI 1.82 to 2.84) doses were administered. Grade ≥ 3 AEs increased clearly in 5 mg (RR: 1.11, 95% CI 1.04 to 1.20) compared to 7.5 mg (RR: 1.05, 95% CI 0.82 to 1.35) and 10 mg (RR: 1.15, 95% CI 0.98 to 1.36). Bayesian analysis demonstrated that 10 mg Bev obtained the maximum time of OS (HR: 0.75, 95% CrI 0.58 to 0.97; probability rank = 0.05) indirectly compared to 5 mg and 7.5 mg Bev. Compared with 5 mg and 7.5 mg Bev, 10 mg Bev also holds the longest duration for PFS (HR: 0.59, 95% CrI 0.43 to 0.82; probability rank = 0.00). In terms of ORR, 10 mg Bev holds the maximum frequency (RR: 2.02, 95% CrI 1.52 to 2.66; probability rank = 0.98) in comparison to 5 mg and 7.5 mg Bev clearly. For grade ≥ 3 AEs, 10 mg Bev has the maximum incidence (RR: 1.15, 95% CrI 0.95 to 1.40, probability rank = 0.67) in comparison to other doses of Bev. CONCLUSION The study suggests that 10 mg dose Bev could be more effective in treating advanced CRC in efficacy, but 5 mg Bev could be more safer in terms of safety.

Abstract
Colorectal cancers are among the most commonly found cancers over the world. In spite of the recent advancements in diagnosis and prognosis, the management of this metastatic condition remains a challenge. The utility of monoclonal antibodies in the healing of patients with colorectal cancer has opened a new chapter in the quest for newer therapies. The resistance to the standard treatment regimen made it mandatory to search for newer targets. Mutagenic alterations in the gene engaged in cellular differentiation and growth pathway have been the reason for resistance to treatment. The newer therapies target the various proteins and receptors involved in the signal transduction and down streaming pathways leading to cell proliferation. This review presents an insight into the newer targeted therapies for colorectal cancer involving tyrosine kinase blockers, epidermal growth factor receptors, vascular endothelial growth factor, immune checkpoint therapy, and BRAF inhibitors.

Abstract
Colorectal cancer (CRC) is the third most diagnosed malignancy and a major leading cause of cancer-related deaths worldwide. Despite advances in therapeutic regimens, the number of patients presenting with metastatic CRC (mCRC) is increasing due to resistance to therapy, conferred by a small population of cancer cells, known as cancer stem cells. Targeted therapies have been highly successful in prolonging the overall survival of patients with mCRC. Agents are being developed to target key molecules involved in drug-resistance and metastasis of CRC, and these include vascular endothelial growth factor, epidermal growth factor receptor, human epidermal growth factor receptor-2, mitogen-activated extracellular signal-regulated kinase, in addition to immune checkpoints. Currently, there are several ongoing clinical trials of newly developed targeted agents, which have shown considerable clinical efficacy and have improved the prognosis of patients who do not benefit from conventional chemotherapy. In this review, we highlight recent developments in the use of existing and novel targeted agents against drug-resistant CRC and mCRC. Furthermore, we discuss limitations and challenges associated with targeted therapy and strategies to combat intrinsic and acquired resistance to these therapies, in addition to the importance of implementing better preclinical models and the application of personalized therapy based on predictive biomarkers for treatment selection.

Abstract
Colorectal cancer (CRC) is the second most lethal cancer worldwide and the prognosis of metastatic CRC (mCRC) remains poor. Recent advancements in translational research have led to the identification of several new therapeutic targets and improved the treatment outcome of patients with tumours harbouring BRAF V600E mutation, (HER2) ErBB2 alterations, NTRK gene fusions and KRAS(G12C) mutation. Improved understanding towards the mechanism of resistance to targeted therapy such as anti-epidermal growth factor receptor antibodies and the evolving role of therapeutic monitoring with circulating tumour DNA (ctDNA) has enabled the longitudinal tracking of clonal evolution during treatment and the individualization of subsequent treatments. To broaden the community-based implementation of precision oncology in directing targeted therapies for patients with gastrointestinal cancers including mCRC, the feasibility of 'Master Protocols' that utilizes ctDNA-based genotyping platforms is currently being evaluated. Such protocols encompass both observational and interventional clinical trials of novel targeted therapies conducted within a large clinical trial network. In this review, we will discuss the latest developments in targeted therapies, and therapeutic strategies for overcoming acquired drug resistance in patients with mCRC.

Abstract
There is a clear association between the molecular profile of colorectal cancer liver metastases (CRCLM) and the degree to which aggressive progression of the disease impacts patient survival. However, much of our knowledge of the molecular behaviour of colorectal cancer cells comes from experimental studies with, as yet, limited application in clinical practice. In this article, we review the current advances in the understanding of the molecular behaviour of CRCLM and present possible future therapeutic applications. This review focuses on three important steps in CRCLM development, progression and treatment: (1) the dissemination of malignant cells from primary tumours and the seeding to metastatic sites; (2) the response to modern regimens of chemotherapy; and (3) the possibility of predicting early progression and recurrence patterns by molecular analysis in liquid biopsy.

Comparative Analysis of First-Line FOLFOX Treatment With and Without Anti-VEGF Therapy in Metastatic Colorectal Carcinoma: A Real-World Data Study. Cancer Control 2023; 30:10732748231202470. [PMID: 37724508 PMCID: PMC10510351 DOI: 10.1177/10732748231202470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 08/21/2023] [Accepted: 08/28/2023] [Indexed: 09/20/2023] Open
Abstract
BACKGROUND FOLFOX (leucovorin calcium [folinic acid], fluorouracil, and oxaliplatin) combined with or without anti-VEGF therapy represents one of the primary first-line treatment options for metastatic colorectal carcinoma (mCRC). However, there is limited comparative data on the impact of anti-VEGF therapy on treatment effectiveness, survival outcomes, and tumor location. METHODS This retrospective, comparative study utilized data from the AIM Cancer Care Quality Program and commercially insured patients treated at medical oncology clinics in the US. We analyzed 1652 mCRC patients who received FOLFOX, of which 1015 (61.4%) were also treated with anti-VEGF therapy (VEGF cohort). RESULTS Patients in the VEGF cohort exhibited a higher frequency of lung (33% vs 23%; P < .001) and liver metastases (74% vs 62%; P < .001), underwent fewer liver surgeries prior to treatment (1.2% vs 3.6%; P = .002), and had a higher proportion of right-sided tumors (27% vs 18%; P = .001). Adjusted analysis revealed no significant difference in overall survival (OS) between patients treated with and without anti-VEGF (median survival: 25.4 vs 26.0 months; P = .4). FOLFOX-only treated patients experienced higher rates of post-treatment hospitalizations (22% vs 15%; P < .001). Notably, left-sided tumors treated with anti-VEGF showed a trend toward decreased OS (median survival: 26.8 vs 33 months; P = .09). CONCLUSION Our real-world data analysis suggests that the addition of anti-VEGF to FOLFOX offers limited and short-lived benefits in the context of mCRC and may provide differential survival benefit based on tumor sidedness.

Abstract
BACKGROUND Previous studies suggest a possible sex-specific response to bevacizumab in metastatic colorectal carcinoma (mCRC), showing a benefit in males, while the effect in females is less significant. METHODS Data from 3369 patients with mCRC enrolled on four first-line randomised trials testing chemotherapy with or without bevacizumab (2000-2007) were pooled. Association between sex and progression-free survival and overall survival (OS) was evaluated by stratified Cox regression model, adjusted for potential confounders. Predictive value was evaluated by interaction effect between sex and treatment. In a pre-planned secondary analysis, analyses were stratified using an age cut point of 60 years to evaluate the possible role of menopausal-related effects. RESULTS Bevacizumab was associated with an improved median OS in males and females, with a 2.3- and 0.6-months benefit, respectively. Stratified by age, bevacizumab resulted in improved OS in males at both age categories. In females at or above the age of 60 (n = 731), bevacizumab resulted in improved OS. However, in females below the age of 60 (n = 634), OS benefit did not reach statistical significance (adjusted hazard ratio = 0.94, 95% confidence interval 0.74-1.20). CONCLUSIONS Our results confirmed the OS benefit from the addition of bevacizumab to first-line chemotherapy in mCRC in both sexes. Among females, the benefit was less than 1 month. For females under the age of 60, there was no survival benefit. These findings could be used to relieve financial toxicity or be redistributed within healthcare systems for other health-related purposes.

Recent and Future Strategies to Overcome Resistance to Targeted Therapies and Immunotherapies in Metastatic Colorectal Cancer. J Clin Med 2022; 11:jcm11247523. [PMID: 36556139 PMCID: PMC9783354 DOI: 10.3390/jcm11247523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/06/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
Colorectal cancer (CRC) is the third most common cause of cancer-related deaths worldwide, and 20% of patients with CRC present at diagnosis with metastases. The treatment of metastatic CRC is based on a fluoropyrimidine-based chemotherapy plus additional agents such as oxaliplatin and irinotecan. To date, on the basis of the molecular background, targeted therapies (e.g., monoclonal antibodies against epidermal growth factor receptor or inhibiting angiogenesis) are administered to improve the treatment of metastatic CRC. In addition, more recently, immunological agents emerged as effective in patients with a defective mismatch repair system. The administration of targeted therapies and immunotherapy lead to a significant increase in the survival of patients; however these drugs do not always prove effective. In most cases the lack of effectiveness is due to the development of primary resistance, either a resistance-inducing factor is already present before treatment or resistance is acquired when it occurs after treatment initiation. In this review we describe the most relevant targeted therapies and immunotherapies and expand on the reasons for resistance to the different approved or under development targeted drugs. Then we showed the possible mechanisms and drugs that may lead to overcoming the primary or acquired resistance in metastatic CRC.

Abstract
OBJECTIVES Metastasectomy in patients with metastatic colorectal cancer (mCRC) confers a significant survival benefit. We hypothesized that conversion to resectability (C2R) correlates with superior overall survival (OS) in patients with unresectable mCRC. METHODS A prospectively registered systematic review (PROSPERO CRD42015024104) of randomized clinical trials published after 2003 was conducted. Exposure of interest was C2R with a primary outcome of OS. Clinical trials were classified based on difference in C2R between study arms (<2%, 2% to 2.9%, ≥3%). Generalized estimating equations were used to measure associations while adjusting for multiple observations from the same trial. RESULTS Of 2902 studies reviewed, 30 satisfied selection criteria (n=13,618 patients). Median C2R was 7.3% (interquartile range [IQR]: 5% to 12.9%), with maximum C2R in the FOLFOX/FOLFIRI+cetuximab arm (28.6%). The median difference in C2R between 2 arms of the same study was 2.3% (IQR: 1.3% to 3.4%) with a maximum difference of 15.4% seen in FOLFOX/FOLFIRI+cetuximab versus FOLFOX/FOLFIRI. Median OS for the entire patient cohort was 20.7 months (IQR: 18.9 to 22.7 mo), with a between group difference of 1.3 months (IQR: -1.2 to 3.6 mo). The median survival difference between the 2 study arms with <2% C2R difference was 0.8 months versus 1.6 months with ≥3% C2R rates . Increasing C2R had an incremental dose-effect response on OS ( P =0.021), and higher response rates correlated with C2R rates ( P =0.003). CONCLUSIONS C2R occurs infrequently and variably in clinical trials enrolling patients with unresectable mCRC. Prioritization of chemotherapeutic agents that enhance C2R might improve OS of patients.

Overall Survival and Progression-Free Survival Comparison of Bevacizumab Plus Chemotherapy Combination Regiment versus Chemotherapy Only Regiment in Previously Untreated Metastatic Colorectal Cancer: Systematic Review and Meta-Analysis. Open Access Maced J Med Sci 2022.

Abstract
BACKGROUND: Colorectal cancer is the third-most common cancer in the world, in which 15%–25% of patients already had metastatic colorectal cancer (mCRC) at the time of diagnosis. The overall survival (OS) of mCRC is poor with the use of chemotherapy.
AIM: This systematic review and meta-analysis aim to examine the outcomes of OS and progression-free survival (PFS) of adding bevacizumab to different chemotherapy regiments compared to chemotherapy regiments only in the treatment of untreated mCRC.
METHODS: Literature searching was done in databases such as PubMed, EBSCO, SCOPUS, and ScienceDirect. The primary outcome measured in this systematic review and meta-analysis was OS, while the secondary outcome was PFS. Hazard ratio (HR) was used as the main summary measure with 95% confidence interval (CI). Publication bias was measured using a funnel plot.
RESULTS: Literature searching resulted in 11 selected studies, 9 selected for meta-analysis. Addition of bevacizumab showed significant better results in OS (HR 0.83, CI 95% 0.74–0.93; p = 0.002; I2 = 29%) and PFS (HR 0.62, 95% CI 0.51–0.75; p < 0.0001, I2 = 78%).
CONCLUSION: The addition of bevacizumab to chemotherapy resulted in better OS and PFS in untreated mCRC. Further studies are needed to confirm PFS benefit from the combination of bevacizumab and chemotherapy due to significant heterogeneity.

Abstract
Aim: To compare pembrolizumab with competing interventions for previously untreated, unresectable or metastatic microsatellite instability-high or mismatch repair-deficient colorectal cancer. Method: Trials were identified via a systematic literature review and synthesized using a Bayesian network meta-analysis with time-varying hazard ratios (HRs). Results: Using intention-to-treat data, HRs for overall survival were generally in favor of pembrolizumab but not statistically significant; however, statistical significance was reached versus all comparators by month 16 when accounting for crossover. Estimated HRs for progression-free survival significantly favored pembrolizumab versus all comparators by month 12. Pembrolizumab was also superior to all comparators in terms of grade ≥3 adverse events. Conclusion: These analyses suggest that pembrolizumab is a highly efficacious and safe treatment in this population.

Abstract
This study expands the understanding of the role of target therapy in improving survival of patients with mCRC based on real-world study results. These data represent potential survival outcomes of Taiwanese patients with mCRC in clinical practice. CRC is the most commonly diagnosed cancer and the third leading cause of cancer-related death in Taiwan. The aim of this study was to evaluate the efficacy of target therapy in combination with chemotherapy for mCRC in Taiwan. This was a real-world, retrospective, observational study in patients diagnosed with mCRC (N=1583). A total of 792 patients received chemotherapy plus target therapy (anti-EGFR therapy, n=180; anti-VEGF therapy, n=612) and 791 patients who received chemotherapy alone. Overall survival (OS) and progression-free survival (PFS) were examined. For RAS wild-type patients, the median OS (mOS) was 34.3 months in the EGFR L (left-sided colon) group, 27.3 months in the VEGF L group, 18.4 months in VEGF R (right-sided colon) group, and 13.8 months in EGFR R group (P<0.001). Median PFS (mPFS) was 9.8 months in the EGFR L group, 8.9 months in the VEGF L group, 6.8 months in VEGF R group, and 5.8 months in EGFR R group. In patients with a RAS mutation, mOS was 25.4 months in the VEGF L group and 19.4 months in the VEGF R group (P=0.167). Judicious treatment allocation in Taiwanese patients with mCRC can result in an mOS of 34.3 months using cetuximab plus chemotherapy for left-sided tumors. An mOS of 48.5 months can be achieved using cetuximab plus chemotherapy in the neoadjuvant setting in mCRC patients with left-sided tumors. This study expands our understanding of the role of target therapy in improving survival of mCRC patients based on real-world study results.

Abstract
BACKGROUND Systemic treatments, namely, either monotherapy or combination therapy, are commonly administered to patients with advanced or metastatic colorectal cancer (CRC). This study aimed to provide the complete efficacy and safety profiles and ranking of systemic therapies for the treatment of unresectable advanced or metastatic CRC. METHODS We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception until June 30, 2021, and also the bibliographies of relevant studies. Randomized controlled trials comparing two or more treatments, namely, at least capecitabine, 5-fluorouracil, leucovorin, irinotecan, bevacizumab, cetuximab, oxaliplatin, or panitumumab were investigated. A network meta-analysis using the Bayesian approach was performed to compare the efficacy and safety of treatments. The surface under the cumulative ranking curve (SUCRA) was calculated for the probability of each treatment as the most effective. The overall response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), adverse events (AEs) grade ≥3, and serious adverse events (SAEs) were evaluated. RESULTS One hundred two publications with 36,147 participants were assigned to 39 different treatments. Among 11 treatments with full information on six outcomes, FOLFIRI/FOLFOX/FOLFOXIRI + bevacizumab significantly improved both the ORR and DCR, compared to FOLFIRI. Although FOLFOX and FOLFIRI/FOLFOX + cetuximab significantly prolonged both OS and PFS, treatments were comparable in terms of AEs grade ≥3 and SAEs. The top highest SUCRA values were observed in the FOLFOXIRI + panitumumab group for ORR (96%) and DCR (99%), FOLFIRI + bevacizumab + panitumumab group for OS (62%) and PFS (54%), and FOLFOXIRI + bevacizumab group for AEs grade ≥3 (59%) and SAEs (59%) outcomes. CONCLUSIONS These findings suggest an available range of systemic treatment therapies with different efficacy and safety profiles with patients. Further investigations of the side effects and mutation status are required to confirm our findings. SYSTEMATIC REVIEW REGISTRATION https://www.crd.york.ac.uk/prospero/, identifier CRD42019127772.

Abstract
Purpose When combined with chemotherapy, bevacizumab improves progression-free survival (PFS) in metastatic colorectal cancer (mCRC). This observational trial was designed to assess the safety and efficacy of bevacizumab plus first-line chemotherapy in a real-world setting in Lebanon. Patients and Methods A non-interventionaL multicenter study of first-LIne AVastin® (bevacizumab) in combination with chEmotherapy in patients with metastatic colorectal cancer (LLIVE) is a multicenter, prospective, Lebanon-based, observational study that enrolled mCRC patients who received first-line bevacizumab plus chemotherapy combination. The primary end point of the study was PFS. Secondary endpoints comprised the overall response rate (ORR) and the safety and tolerability of bevacizumab. Results A total of 196 patients were enrolled between July 2010 and August 2013. The median duration of follow-up was 11 months. Median duration of bevacizumab treatment was 4 months with FOLFOX being the chiefly chemotherapy regimen used in the first-line setting (26%). Median PFS was 8.22 months (95% confidence interval (CI): 7.005–9.443). The ORR was 50.3% (complete response 7.5%, partial response 42.8%). The most common adverse event encountered was hypertension (28%) followed by epistaxis (4.8%), diarrhea (4%), anemia (4%) and headache (4%). Grade 3/4 adverse events occurred in 15.2% of patients. Conclusion The trial further substantiated the efficacy and safety of bevacizumab and chemotherapy in the first-line treatment of mCRC patients in Lebanon.

Abstract
OBJECTIVE This study aims to evaluate the effects of bevacizumab and propranolol from the point of view of a possible antiangiogenic effect in a model of primary nasal polyp (NP) tissue culture. METHODS NP samples of 21 patients and normal healthy nasal mucosa samples of 7 patients were cultured. Samples were divided into four groups as follows (healthy nasal mucosa, NP without any treatment, NP treated with propranolol, NP treated with bevacizumab). Cultured tissues were formalin fixed and paraffin embedded. Tissue sections and immunohistochemical VEGF-A, angiopoietin-1 (Ang-1), and angiopoietin-2 (Ang-2) expressions were evaluated. ELISA was also performed for each one of them. RESULTS Both propranolol and bevacizumab significantly decreased the expressions of VEGF-A and Ang-1, and they significantly increased the expression of Ang-2 in comparison to the control NP group. In the healthy nasal mucosa group, no significant expression of VEGF-A was seen, a slight (+) Ang-1 expression, and a high (+++) Ang-2 expression were observed. CONCLUSION Bevacizumab and propranolol exert an antiangiogenic effect on NP tissues, mainly by decreasing VEGF-A and Ang-1 expression, increasing Ang-2 expression.

Abstract
Immunotherapy in the metastatic setting has drastically altered the landscape of treatment for various types of malignancy, including colorectal cancer. The category of immune checkpoint inhibitors has especially emerged as a class of therapy predicated on a more comprehensive understanding of immune cell-cancer cell regulation and evolution of the tumor microenvironment over time. Strategies including adoptive cellular therapies, tumor vaccines, and antibodies have also demonstrated the ability to enhance antitumor immunity. In this article, we provide a comprehensive review of the current landscape of immunotherapeutic strategies in colorectal cancer and provide insight into how these strategies may evolve in the next decade and be adapted to more localized forms of cancers of the colon and rectum. We provide particular focus on various combination approaches under investigation for reversing cancer-induced immunosuppression, especially in mismatch repair-proficient/microsatellite-stable colorectal tumors. Finally, we summarize current understanding on a recently identified integral factor in local immune regulation, the colonic microbiome. The aim of this article is to identify current challenges and barriers to improvement and to specify opportunities for applying knowledge in the immunotherapy sphere to rational design of clinical trials intended to improve survival and related outcomes in patients treated in the neoadjuvant setting.

Abstract
OBJECTIVE Bevacizumab has an important and evolving role in improving outcomes in patients with metastatic colorectal cancer (mCRC) worldwide and was approved in China in 2010. However, there are limited real-world data on the efficacy and safety of chemotherapy regimens combined with bevacizumab in Chinese patients with mCRC. This observational, phase IV trial study aimed to obtain more experience on the efficacy and safety of bevacizumab combined with chemotherapy in Chinese mCRC patients. METHODS Between September 2013 and November 2016, patients with histologically confirmed mCRC were enrolled in a prospective, multicenter, observational, non-interventional phase IV trial at 26 centers across China. Eligible patients received different chemotherapeutic regimens combined with bevacizumab. The efficacy and safety data in the intention-to-treat study population were analyzed. RESULTS A total of 611 patients were included in the efficacy analysis. The median overall survival and median progression-free survival was 18.00 and 10.05 months, respectively. The objective response rate was 21.00% and disease control rate was 89.40%. In subgroup analyses, the survival differences were observed according to metastatic status, duration of treatment and elevation in blood pressure. A total of 613 patients were evaluable for safety assessments. And 569 (92.82%) patients reported at least one adverse event (AE), and 151 (24.63%) experienced grade 3 or higher AEs. The incidence of bevacizumab-associated AEs of special interest was reported in 31 (5.06%) patients with hypertension (n=12), abscesses and fistulae (n=7), bleeding (n=6), proteinuria (n=3), gastrointestinal perforation (n=2) and venous thrombotic events (n=1). CONCLUSIONS This observational phase IV trial broadens our experience and knowledge of bevacizumab in the Chinese population and provides a good indication of its overall efficacy and safety. Bevacizumab in combination with chemotherapy offers clinical benefits to Chinese patients with mCRC and has an acceptable and manageable safety profile.

Abstract
Colorectal cancer is a clinically and molecularly heterogeneous disease. Currently, extended RAS and BRAF mutation testing is obligatory in routine clinical practice before starting any treatment in the metastatic setting. Treatment decision making also includes assessment of the clinical condition of the patient, definition of the treatment goal, and consideration of the primary tumor site. Biological treatment is part of the first-line drug combination unless contraindicated. Mutational status is significantly associated with the outcome of patients and is strongly predictive for anti-EGFR-targeted therapy. The prognosis of RAS mutant CRC is clearly inferior to wild-type cases. RAS remains an elusive target, and specific treatment options are not yet available. Recently, promising results of a direct KRAS G12C inhibitor have been reported; however, further confirmation is needed. The biomarker landscape in mCRC is evolving; new promising markers are awaited with the chance of more precise targeted treatment.

Abstract
We performed a meta-analysis to fully investigate the hypertension of anti-VEGF mAbs in cancer patients. Databases were searched for randomized controlled trials (RCTs) treated with anti-VEGF mAbs till January 2021. The relevant RCTs in cancer patients treated with anti-VEGF mAbs were retrieved and the systematic evaluation was conducted. One hundred and five RCTs and 65358 patients were included. Our study suggests that anti-VEGF mAbs significantly increased the risks of all-grade (RR, 3.22; 95%CI, 2.83-3.65; p < 0.00001; I2=71%) and high-grade (RR, 6.15; 95%CI, 5.58-6.78; p < 0.00001; I2=48%) hypertension in cancer patients. Those risks may be dependent on drug type. Icrucumab did not association with an increased risk of hypertension. The RR of hypertension did not vary significantly according to the type of cancer, line of therapy, and treatment duration. The available data suggested that the use of anti-VEGF mAbs were associated with a significantly increased risk of hypertension.

Abstract
IMPORTANCE Although bevacizumab is a standard of care in combination treatments for metastatic colorectal cancer (mCRC), its clinical benefit has been limited. OBJECTIVE To determine whether sequential scheduling of bevacizumab administration in combination with chemotherapy improves treatment efficacy in patients with mCRC, in keeping with the tumor vascular normalization hypothesis. DESIGN, SETTING, AND PARTICIPANTS This open-label, randomized clinical phase 3 trial was conducted from May 8, 2012, to December 9, 2015, at 3 Italian centers. Patients aged 18 to 75 years with unresectable, previously untreated, or single line-treated mCRC were recruited. Follow-up was completed December 31, 2019, and data were analyzed from February 26 to July 24, 2020. INTERVENTIONS Patients received 12 biweekly cycles of standard oxaliplatin-based regimens (modified FOLFOX-6 [levo-folinic acid, fluorouracil, and oxaliplatin]/modified CAPOX [capecitabine and oxaliplatin]) plus bevacizumab administered either on the same day as chemotherapy (standard arm) or 4 days before chemotherapy (experimental arm). MAIN OUTCOMES AND MEASURES The primary end point was the objective response rate (ORR) measured with Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary end points included progression-free survival, overall survival, safety, and quality of life (QOL). RESULTS Overall, 230 patients (136 men [59.1%]; median age, 62.3 [interquartile range, 53.3-67.6] years) were randomly assigned to the standard arm (n = 115) or the experimental arm (n = 115). The median duration of follow-up was 68.3 (95% CI, 61.0-70.0) months. No difference in ORR (57.4% [95% CI, 47.8%-66.6%] in the standard arm and 56.5% [95% CI, 47.0-65.7] in the experimental arm; P = .89) or progression-free survival (10.5 [95% CI, 9.1-12.3] months in the standard arm and 11.7 [95% CI, 9.9-12.9] months in the experimental arm; P = .15) was observed. However, the median overall survival was 29.8 (95% CI, 22.5-41.1) months in the experimental arm compared with 24.1 (95% CI, 18.6-29.8) months in the standard arm (adjusted hazard ratio, 0.73; 95% CI, 0.54-0.99; P = .04). Moreover, the experimental arm was associated with a significant reduction in the rate of severe diarrhea (6 [5.3%] vs 19 [16.5%]; P = .006) and nausea (2 [1.8%] vs 8 [7.0%]; P = .05) and improved physical functioning (mean [SD] change from baseline, 0.65 [1.96] vs -7.41 [2.95] at 24 weeks; P = .02), and constipation scores (mean [SD] change from baseline, -17.2 [3.73] vs -0.62 [4.44]; P = .003). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, sequential administration of bevacizumab plus chemotherapy did not improve ORR, the primary end point. However, the overall survival advantage, fewer adverse effects, and better health-related QOL associated with sequential bevacizumab administration might provide the basis for exploring antiangiogenic combination treatments with innovative perspectives.

Abstract
INTRODUCTION In Taiwan, given the discrepancy between current treatment guidelines and reimbursement options, patients might require a tool to support their decision-making process when selecting a regimen for metastatic colorectal cancer, especially therapeutic strategies, and subsequent costs, along with efficacy and safety outcomes. Therefore, we developed a patient decision aid (PDA) to support patients in choosing between treatment options recommended based on the current evidence and those reimbursed by the Taiwanese National Health Insurance. METHODS By carefully reviewing the updated data and then interpreting the clinical tool, we conducted a needs assessment using a serial questionnaire to test for a step-by-step adjustment of the PDA. RESULTS Patients, their relatives, and medical team members were most concerned about outcomes, such as overall survival, progression-free survival, objective response rate, tumor shrinkage to resectable status, total medical cost, severe gastrointestinal perforation, and severe skin reaction. After a serial alpha test for quality, we performed quantitative evaluation and beta tests, revealing average scores of more than 4 points (on a scale of 1-5) for both perceptibility and utility. CONCLUSIONS The present findings suggest that PDAs are useful and supplement the shared decision-making practice, helping patients make decisions about preferences and consider the pros and cons of treatment regimens, along with insurance reimbursement options.

Abstract
Targeting tumor-driven angiogenesis is an effective strategy in the management of metastatic colorectal cancer (mCRC); however, the choice of second-line therapy is complicated by the availability of several drugs, the occurrence of resistance and the lack of validated prognostic and predictive biomarkers. This review examines the use of angiogenesis-targeted therapies for the second-line management of mCRC patients. Mechanisms of resistance and anti-placental growth factor agents are discussed, and the role of aflibercept, a recombinant fusion protein consisting of portions of human vascular endothelial growth factor receptor (VEGFR)-1 and VEGFR-2, is highlighted. The novel mechanism of action of aflibercept makes it a useful second-line agent in mCRC patients progressing after oxaliplatin-based chemotherapy, as well as in those with resistance after bevacizumab.

Abstract
Colorectal cancer (CRC) is the third most frequently detected type of cancer, and the second most common cause of cancer‑related mortality globally. The American Cancer Society predicted that approximately 147,950 individuals would be diagnosed with CRC, out of which 53,200 individuals would succumb to the disease in the USA alone in 2020. CRC‑related mortality ranks third among both males and females in the USA. CRC arises from 3 major pathways: i) The adenoma‑carcinoma sequence; ii) serrated pathway; and iii) the inflammatory pathway. The majority of cases of CRC are sporadic and result from risk factors, such as a sedentary lifestyle, obesity, processed diets, alcohol consumption and smoking. CRC is also a common preventable cancer. With widespread CRC screening, the incidence and mortality from CRC have decreased in developed countries. However, over the past few decades, CRC cases and mortality have been on the rise in young adults (age, <50 years). In addition, CRC cases are increasing in developing countries with a low gross domestic product (GDP) due to lifestyle changes. CRC is an etiologically heterogeneous disease classified by tumor location and alterations in global gene expression. Accumulating genetic and epigenetic perturbations and aberrations over time in tumor suppressor genes, oncogenes and DNA mismatch repair genes could be a precursor to the onset of colorectal cancer. CRC can be divided as sporadic, familial, and inherited depending on the origin of the mutation. Germline mutations in APC and MLH1 have been proven to play an etiological role, resulting in the predisposition of individuals to CRC. Genetic alterations cause the dysregulation of signaling pathways leading to drug resistance, the inhibition of apoptosis and the induction of proliferation, invasion and migration, resulting in CRC development and metastasis. Timely detection and effective precision therapies based on the present knowledge of CRC is essential for successful treatment and patient survival. The present review presents the CRC incidence, risk factors, dysregulated signaling pathways and targeted therapies.

Abstract
Since the late 1990s, therapy for metastatic colorectal cancer (mCRC) has changed considerably, and the combination of doublet or triplet chemotherapy and a targeted agent are now routinely used. The targeting of angiogenesis, the development of new blood vessels, represents a key element in the overall treatment strategy. Since the approval in 2004 of the first anti-angiogenetic drug, multiple agents have been approved and others are currently under investigation. We present an overview of the recent literature on approved systemic treatment of mCRC, with a focus on anti-angiogenic drugs, and current treatment approaches, and elaborate on the future role of angiogenesis in colorectal cancer as seen from a clinical perspective. The treatment of mCRC, in general, has changed from "one strategy fits all" to a more personalized approach. This is, however, not entirely the case for anti-angiogenetic treatments, partly due to a lack of validated biomarkers. The anti-angiogenetic standard treatment at the present primarily includes monoclonal antibodies. The therapeutic field of angiogenesis, however, has received increased interest after the introduction of newer combinations. These approaches will likely change the current treatment strategy, once again, to the overall benefit of patients.

Abstract
The approval of a new drug for cancer treatment by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) is based on positive, well-designed randomized phase III clinical trials (RCTs). However, not all of them are analyzed to support the recommendations. For this reason, there are different scales to quantify and evaluate the quality of RCTs and the magnitude of the clinical benefits of new drugs for treating solid tumors. In this review, we discuss the value of the progression-free survival (PFS) as an endpoint in RCTs and the concordance between it and the overall survival (OS) as a measure of the quality of clinical trial designs. We summarize and analyze the different scales to evaluate the clinical benefits of new drugs such as the The American Society of Clinical Oncology value framework (ASCO-VF-NHB16) and European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) and the concordance between them, focusing on metastatic colorectal cancer (mCRC). We propose several definitions that would help to evaluate the quality of RCT, the magnitude of clinical benefit and the appropriate approval of new drugs in oncology.

Abstract
Background Outcomes are poorer in metastatic colorectal cancer (mCRC) patients with BRAF V600E mutations than those without it, but the effect of these mutations on treatment response is unclear. This real-world study assessed the effects of antiangiogenic-based treatment and systemic inflammatory factors on outcomes in patients with BRAF V600-mutated mCRC. Methods This real-world, multicenter, retrospective, observational study included patients with BRAF V600-mutated mCRC treated in eight hospitals in Spain. The primary endpoints were overall survival (OS) and progression-free survival (PFS); overall response rate (ORR) and disease control rate (DCR) were also assessed. The effect of first- and second-line treatment type on OS, PFS, ORR, and DCR were evaluated, plus the impact of systemic inflammatory markers on these outcomes. A systemic inflammation score (SIS) of 1–3 was assigned based on one point each for platelet-lymphocyte ratio (PLR) ≥200, neutrophil-lymphocyte ratio (NLR) ≥3, and serum albumin < 3.6 g/dL. Results Of 72 patients, data from 64 were analyzed. After a median of 69.1 months, median OS was 11.9 months and median first-line PFS was 4.4 months. First-line treatment was triplet chemotherapy-antiangiogenic (12.5%), doublet chemotherapy-antiangiogenic (47.2%), doublet chemotherapy-anti-EGFR (11.1%), or doublet chemotherapy (18.1%). Although first-line treatment showed no significant effect on OS, antiangiogenic-based regimens were associated with prolonged median PFS versus non-antiangiogenic regimens. Negative predictors of survival with antiangiogenic-based treatment were NLR, serum albumin, and SIS 1–3, but not PLR. Patients with SIS 1–3 showed significantly prolonged PFS with antiangiogenic-based treatment versus non-antiangiogenic-based treatment, while those with SIS=0 showed no PFS benefit. Conclusions Antiangiogenic-based regimens, SIS, NLR, and albumin were predictors of survival in patients with mCRC, while SIS, NLR and serum albumin may predict response to antiangiogenic-based chemotherapy. Trial registration GIT-BRAF-2017-01.

Abstract
Colorectal cancer (CRC), the third most common type of cancer, is the second leading cause of cancer-related mortality rates worldwide. Although modern research was able to shed light on the pathogenesis of CRC and provide enhanced screening strategies, the prevalence of CRC is still on the rise. Studies showed several cellular signaling pathways dysregulated in CRC, leading to the onset of malignant phenotypes. Therefore, analyzing signaling pathways involved in CRC metastasis is necessary to elucidate the underlying mechanism of CRC progression and pharmacotherapy. This review focused on target genes as well as various cellular signaling pathways including Wnt/β-catenin, p53, TGF-β/SMAD, NF-κB, Notch, VEGF, and JAKs/STAT3, which are associated with CRC progression and metastasis. Additionally, alternations in methylation patterns in relation with signaling pathways involved in regulating various cellular mechanisms such as cell cycle, transcription, apoptosis, and angiogenesis as well as invasion and metastasis were also reviewed. To date, understanding the genomic and epigenomic instability has identified candidate biomarkers that are validated for routine clinical use in CRC management. Nevertheless, better understanding of the onset and progression of CRC can aid in the development of early detection molecular markers and risk stratification methods to improve the clinical care of CRC patients.

Abstract
Colorectal cancer (CRC) is a commonly diagnosed malignancy. The prognosis of patients with unresectable, metastatic colorectal cancer (mCRC) is dismal and medical treatment is mainly palliative in nature. Although chemotherapy remains the backbone of treatment, the landscape is changing with the understanding of its heterogeneity and molecular biology. First-line therapy relies on a combination of chemotherapy and targeted therapies, according to clinical patient characteristics and tumor molecular profile. Here we review current evidence from randomized clinical trials for using chemotherapy doublets or triplets, and for the addition of bevacizumab or anti-epidermal growth factor receptor (EGFR) agents. Novel therapies developed for small, selected populations are also discussed.

Abstract
BACKGROUND Simulation models utilizing real-world data have potential to optimize treatment sequencing strategies for specific patient subpopulations, including when conducting clinical trials is not feasible. We aimed to develop a simulation model to estimate progression-free survival (PFS) and overall survival for first-line doublet chemotherapy with or without bevacizumab for specific subgroups of metastatic colorectal cancer (mCRC) patients based on registry data. METHODS Data from 867 patients were used to develop two survival models and one logistic regression model that populated a discrete event simulation (DES). Discrimination and calibration were used for internal validation of these models separately and predicted and observed medians and Kaplan-Meier plots were compared for the integrated DES. Bootstrapping was performed to correct for optimism in the internal validation and to generate correlated sets of model parameters for use in a probabilistic analysis to reflect parameter uncertainty. RESULTS The survival models showed good calibration based on the regression slopes and modified Hosmer-Lemeshow statistics at 1 and 2 years, but not for short-term predictions at 0.5 years. Modified C-statistics indicated acceptable discrimination. The simulation estimated that median first-line PFS (95% confidence interval) of 219 (25%) patients could be improved from 175 days (156-199) to 269 days (246-294) if treatment would be targeted based on the highest expected PFS. CONCLUSIONS Extensive internal validation showed that DES accurately estimated the outcomes of treatment combination strategies for specific subpopulations, with outcomes suggesting treatment could be optimized. Although results based on real-world data are informative, they cannot replace randomized trials.

Prognostic role of a new index (multi inflammatory index) in patients with metastatic colorectal cancer: results from the randomized ITACa trial. Ther Adv Med Oncol 2020; 12:1758835920958363. [PMID: 33062063 PMCID: PMC7534088 DOI: 10.1177/1758835920958363] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 08/19/2020] [Indexed: 12/19/2022] Open
Abstract
Aims We created a new index (Multi Inflammatory Index, MII) composed of an inflammatory index [neutrophil-to lymphocyte-ratio (NLR): MII-1; platelet-to-lymphocyte ratio (PLR): MII-2; or systemic immune-inflammation index (SII): MII-3] and C-reactive protein (CRP). Our aim was to evaluate the prognostic and/or predictive capacity of the MII in the randomized ITACa (Italian Trial in Advanced Colorectal Cancer) study on patients with metastatic colorectal cancer undergoing first-line chemotherapy. Methods Between November 2007 and March 2012, baseline NLR, PLR; SII and CRP were available for 131 patients, 66 receiving chemotherapy plus bevacizumab and 65 receiving chemotherapy alone. Results Patients with low (<25) MII-1 levels had a better outcome than those with high (⩾25) levels: median progression-free survival (PFS) was 12.4 versus 8.9 months [hazard ratio (HR) = 1.74, 95% confidence interval (CI) 1.21-2.51, p = 0.003] and median overall survival (OS) was 30.9 months versus 15.0 months (HR = 2.05, 95% CI 1.40-3.02, p = 0.0002), respectively. Similar results were obtained for patients with low (<1424) MII-2 levels compared with those with high (⩾1424) levels: median PFS was 12.6 versus 8.9 months (HR = 1.95, 95% CI 1.35-2.82, p = 0.0004) and median OS was 32.4 versus 14.6 months, respectively (HR = 2.42, 95% CI 1.64-3.57, p < 0.0001). Patients with low (<6068) MII-3 levels had a longer median PFS and OS than those with high (⩾6068) levels: 12.6 versus 8.9 months (HR = 1.91, 95% CI 1.33-2.76, p = 0.005) and 30.9 versus15.0 months (HR = 2.10, 95% CI 1.43-3.09, p = 0.0002), respectively. Following adjustment for clinical covariates, multivariate analysis confirmed all MII indexes as independent prognostic factors for predicting PFS and OS. Conclusion All MII indexes appear to be useful as prognostic markers.

Abstract
This study aimed to investigate the efficacy and safety of systemic therapies in the treatment of unresectable advanced or metastatic colorectal cancer. Predicted hazard ratios (HRs) and their 95% credible intervals (CrIs) for overall survival (OS) were calculated from the odds ratio (OR) for the overall response rate and/or HR for progression-free survival using multivariate random effects (MVRE) models. We performed a network meta-analysis (NMA) of 49 articles to compare the efficacy and safety of FOLFOX/FOLFIRI±bevacizumab (Bmab)/cetuximab (Cmab)/panitumumab (Pmab), and FOLFOXIRI/CAPEOX±Bmab. The NMA showed significant OS improvement with FOLFOX, FOLFOX+Cmab, and FOLFIRI+Cmab compared with that of FOLFIRI (HR = 0.84, 95% CrI = 0.73-0.98; HR = 0.76, 95% CrI = 0.62-0.94; HR = 0.80, 95% CrI = 0.66-0.96, respectively), as well as with FOLFOX+Cmab and FOLFIRI+Cmab compared with that of FOLFOXIRI (HR = 0.69, 95% CrI = 0.51-0.94 and HR = 0.73, 95% CrI = 0.54-0.97, respectively). The odds of adverse events grade ≥3 were significantly higher for FOLFOX+Cmab vs. FOLFIRI+Bmab (OR = 2.34, 95% CrI = 1.01-4.66). Higher odds of events were observed for FOLFIRI+Pmab in comparison with FOLFIRI (OR = 2.16, 95% CrI = 1.09-3.84) and FOLFIRI+Bmab (OR = 3.14, 95% CrI = 1.51-5.89). FOLFOX+Cmab and FOLFIRI+Bmab showed high probabilities of being first- and second-line treatments in terms of the efficacy and safety, respectively. The findings of the efficacy and safety comparisons may support the selection of appropriate treatments in clinical practice. PROSPERO registration: CRD42020153640.

Abstract
PURPOSE To assess the effects of bevacizumab plus modified fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) as first-line treatment of RAS mutant unresectable colorectal liver metastases. METHODS From October 2013 to December 2017, patients with RAS mutant unresectable liver-limited metastases from colorectal cancer were randomly assigned to receive mFOLFOX6 plus bevacizumab (arm A) or mFOLFOX6 alone (arm B). The resectability of liver metastases was determined by a local multidisciplinary team. The primary end point was the actual rate of patients converted to R0 resection for liver metastases. Secondary end points included tumor response, survival, and toxicity. The block randomization method was used. RESULTS The intention-to-treat population comprised 241 patients. A total of 121 patients were randomly assigned to arm A and 120 to arm B. The median follow-up time was 37.0 months for all patients. The R0 resection rates for liver metastases were 22.3% (27 of 121 patients) in arm A and 5.8% (7 of 120 patients) in arm B, with a significant difference (P < .01). Patients in arm A had significantly better objective response rates (54.5% v 36.7%; P < .01), median progression-free survival (9.5 v 5.6 months; P < .01) and median overall survival (25.7 v 20.5 months; P = .03) compared with those in arm B. The addition of bevacizumab was associated with more frequent proteinuria (9.9% v 3.3%; P = .04) and hypertension (8.3% v 2.5%; P < .05). CONCLUSION For patients with initially unresectable RAS mutant colorectal liver metastases, bevacizumab combined with mFOLFOX6 increased the resectability of liver metastases and improved response rates and survival compared with mFOLFOX6 alone.

Effectiveness of bevacizumab in first- and second-line treatment for metastatic colorectal cancer: ITACa randomized trial. Ther Adv Med Oncol 2020; 12:1758835920937427. [PMID: 32754229 PMCID: PMC7378711 DOI: 10.1177/1758835920937427] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Accepted: 05/27/2020] [Indexed: 12/20/2022] Open
Abstract
Background: Cancer trials involving multiple treatment lines substantially increase our
understanding of therapeutic strategies. However, even when the primary
end-point of these studies is progression-free survival (PFS), their
statistical analysis usually focuses on each line separately, or does not
consider repeated events, thus missing potentially relevant information.
Consequently, the evaluation of the effectiveness of treatment strategies is
highly impaired. Methods: We evaluated the potentially different effect of bevacizumab (B) administered
for the first- or second-line treatment of metastatic colorectal cancer
(mCRC) in the ITACa (Italian Trial in Advanced Colorectal Cancer) randomized
trial. The ITACa trial consisted of two arms: first-line chemotherapy (CT)+B
followed by second-line CT alone versus first-line CT alone
followed by second-line CT+B or CT+B+cetuximab according to KRAS status. Cox
models for repeated disease progression were performed, and potential
selection bias was adjusted using the inverse probability of censoring
weighting method. Hazard ratios (HR) [95% confidence interval (CI)] for PFS
(primary endpoint) were reported. Results: The overall effect of B across the two lines resulted in a HR = 0.80 (95% CI
0.68–0.95, p = 0.008). Evaluating the differential effect
of B in first- and second-line, the addition of B to first-line chemotherapy
(CT) produced a 10% risk reduction (HR = 0.90, 95% CI 0.72–1.12,
p = 0.340) versus CT alone; B added to
second-line CT produced a 36% risk reduction (HR = 0.64, 95% CI 0.49–0.84,
p = 0.0011) versus CT alone. Conclusion: Our results seem to suggest that B confers a PFS advantage when administered
in combination with second-line chemotherapy, which could help to improve
current international guidelines on optimal sequential treatment
strategies.

Abstract
BACKGROUND Targeted drugs including bevacizumab, cetuximab, and panitumumab have been widely used during the management of patients diagnosed with colorectal carcinoma, especially as palliative treatment. The present meta-analysis was performed to evaluate the fatal adverse events (FAEs) of targeted drugs including bevacizumab, cetuximab, and panitumumab in patients with colorectal cancer. PATIENTS AND METHODS Studies of prospective, randomized, and controlled feature from EMBASE, Medline, and Cochrane Library, which reported FAEs potentially associated with bevacizumab, cetuximab, and panitumumab were adopted. Clinical characteristics and FAEs were collected from the enrolled literatures, with the quality of which been evaluated. Pooled analysis of FAEs, caused by each agent as first line, second/further line, and adjuvant treatment were performed with relative risks (RRs) and their corresponding 95% confidence intervals (CIs) in software RevMan 5.3. RESULTS Thirty-one studies including 25,939 patients were brought into the final analysis. The RR and its 95% CI of the FAEs among all the agents including bevacizumab, cetuximab, and panitumumab was 1.07 (95% CI, 0.89-1.29; P = .50). The RRs and their 95% CIs of the FAEs as first line, second or further line, and adjuvant treatment related to bevacizumab were 0.91 (95% CI, 0.62-1.32; P = .61), 1.14 (95% CI, 0.57-2.28; P = .71), and 1.10 (95% CI, 0.67-1.79; P = .72). The RRs and their 95% CIs of the FAEs as first line, second or further line, and adjuvant treatment related to cetuximab were 1.02 (95% CI, 0.60-1.76; P = .93), 2.51 (95% CI, 0.49-12.88; P = .27), and 2.40 (95% CI, 1.00-5.77; P = .05). The RRs and their 95% CIs of the FAEs as first line, second or further line treatment related to panitumumab were 1.40 (95% CI, 0.89-2.18; P = .14) and 0.68 (95% CI, 0.43-1.09; P = .11), respectively. CONCLUSIONS The present meta-analysis did not show any significantly increased RR of FAEs belonging to bevacizumab, cetuximab, or panitumumab, whether as first line, second/further line, or adjuvant treatment among patients with colorectal carcinoma comparing to placebo or blank treatment.

Abstract
The aim of the present paper is to provide optimal allocations for comparative clinical trials with survival outcomes. The suggested targets are derived adopting a compound optimization strategy based on a subjective weighting of the relative importance of inferential demands and ethical concerns. The ensuing compound optimal targets are continuous functions of the treatment effects, so we provide the conditions under which they can be approached by standard response-adaptive randomization procedures, also guaranteeing the applicability of the classical asymptotic inference. The operating characteristics of the suggested methodology are verified both theoretically and by simulation, including the robustness to model misspecification. With respect to the other available proposals, our strategy always assigns more patients to the best treatment without compromising inference, taking into account estimation efficiency and power as well. We illustrate our procedure by redesigning two real oncological trials.

Efficacy and Safety of Proposed Bevacizumab Biosimilar BE1040V in Patients With Metastatic Colorectal Cancer: A Phase III, Randomized, Double-blind, Noninferiority Clinical Trial. Clin Ther 2020; 42:848-859. [PMID: 32334845 DOI: 10.1016/j.clinthera.2020.03.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 12/30/2019] [Accepted: 03/16/2020] [Indexed: 01/04/2023]
Abstract
PURPOSE The purpose of this study was to compare the efficacy and safety of a proposed bevacizumab biosimilar to those of the reference product in patients with metastatic colorectal cancer (mCRC). METHODS This Phase III, multicenter, randomized, double-blind (patient- and assessor-blind), active-controlled, 2-armed, parallel-group, noninferiority trial was conducted in patients with histologically verified colorectal cancer with evidence of at least 1 metastasis. Patients with mCRC were randomized 2:1 to receive 5 mg/kg IV of either study drug plus FOLFIRI-3 (with repeated irinotecan 100 mg/m2 60-min infusion on day 3) or the reference drug plus FOLFIRI-3 every 2 weeks for 1 year. Progression-free survival (PFS) was the primary end point, and overall survival, objective response rate, and time to treatment failure as well as safety and immunogenicity were secondary end points. The population assessable for PFS was per protocol, and the intention-to-treat population was used for sensitivity analysis. Safety was assessed based on reports of adverse events, laboratory test results, and vital sign measurements. FINDINGS A total of 126 patients were enrolled; PFS values in the biosimilar and reference arms were 232 days (7.7 months) and 210 days (7 months), respectively (P = 0.47). The hazard ratio of the biosimilar arm versus the reference arm was 0.79 in the per-protocol population (90% CI, 0.46-1.35; P = 0.47). The upper limit for the 2-sided 90% CI was lower than the margin of 1.44, indicating that the biosimilar drug was noninferior to the reference drug. The hazard ratio for overall survival in the intent-to-treat population was 0.99 (95% CI, 0.55-1.80; P = 0.99). The difference between other efficacy end points among the groups was not statistically significant. No significant difference was observed in the comparison of the two arms for safety. The antidrug antibody was positive in 1 patient in each arm. IMPLICATIONS The proposed biosimilar BE1040V was noninferior to the reference product in terms of efficacy in the treatment of mCRC, and tolerability was comparable between the 2 drugs. ClinicalTrials.gov identifier: NCT03288987.
