This monocentric retrospective study included 70 consecutive relapsed/refractory Hodgkin lymphoma (RR-HL) patients receiving reduced-intensity allogeneic stem cell transplantation (alloSCT). We evaluated overall and progression-free survival (OS, PFS), graft-versus host disease/relapse-free survival (GFRS), and chronic GVHD-free OS (cGVHD-free OS) defined as OS without moderate-to-severe cGVHD. Patients had a median age of 33 years (range, 18-60 years), 23% had refractory disease (SD/PD). Donors were HLA identical (39%), unrelated (30%), or haploidentical (31%). Median follow-up was 6.2 years. Five-year OS was 59% and PFS was 49%. NRM was 16% at 1 year. 44% of patients had cGVHD, and 14% moderate-to-severe cGVHD at last follow-up. GFRS and cGVHD-free OS were 26 and 48% at 5 years. In multivariate analysis, resistant disease at alloSCT impacted survival and GFRS. In conclusion, disease response before alloSCT impacts survival and GFRS. GVHD outcomes may help comparing the long-term effects of the new salvage treatments that bridge patients to alloSCT.

Plerixafor 'on demand' after chemotherapy plus granulocyte-colony-stimulating factor (G-CSF) is efficient in peripheral stem cell mobilization, but the timing of administration and criteria for patient selection are under investigation. To devise an algorithm for the 'on demand' use of plerixafor at the first mobilization attempt, we analyzed the kinetics of hematopoietic recovery and peripheral blood CD34+ cells in 107 patients treated with high-dose cyclophosphamide plus G-CSF. Fifty-one patients with myeloma were treated with cyclophosphamide 3-4 g/m2 on day 0 followed by G-CSF 10 μg/kg from day + 6, and 56 patients with lymphoma received cyclophosphamide 6-7 g/m2 followed by G-CSF 5 μg/kg from day + 1. Peripheral blood CD34+ cell monitoring was started on day + 8 in patients with myeloma and day + 10 in patients with lymphoma. The outcome of interest was a collection of ≤ 2 × 106 CD34+/kg. By a multivariate logistic regression model, CD34+ cell count < 10/μL at leukocyte recovery (> 1000/μL) or leukocyte count < 1000/μL after day + 12 in myeloma and day + 14 in lymphoma predicted the failure of mobilization by 2.7 and 2.8 times ( p = 0.001 and p = 0.02) with a sensitivity of 89% and specificity of 88%, respectively. Plerixafor 'on demand' may be considered in patients with myeloma and lymphoma with delayed hematopoietic recovery and < 10/μL CD34+ cells, as a first-line mobilization strategy.

Lenalidomide is effective against relapsed chronic lymphocytic leukemia ( CLL). We report the first case of long-term molecular remission with continuous lenalidomide treatment in a young patient with CLL relapsed to multiple treatments. Minimal residual disease was assessed by nested polymerase chain reaction on bone marrow samples with patient-specific primers. A 20-yr-old patient with standard-risk CLL was treated with lenalidomide after multiple relapses and achieved a 4 yr long complete molecular response with minimal toxicities. Published biologic data support that lenalidomide induces an immune-mediated control of CLL, and our case suggests that long-term treatment with lenalidomide is effective at a molecular level in patients with relapsed CLL.

Abstract: Multiple myeloma relapsing after allogeneic stem cell transplantation (alloSCT) has a poor outcome. To assess the safety and efficacy of bortezomib and dexamethasone (VD) combination followed by donor lymphocyte infusions (DLIs) in myeloma patients relapsing or progressing after alloSCT, a prospective phase II study was designed. The treatment plan consisted of three VD courses followed by escalated doses of DLIs in case of response or at least stable disease. Nineteen patients were enrolled with a median age of 57 years (range, 33 to 67); 14 patients were allografted from human leukocyte antigen–identical siblings and 5 from alternative donors. Sixteen of 19 patients received the planned treatment, but 3 patients did not: 2 patients because of disease progression and 1 refused. After the VD phase the response rate was 62%, with 1 complete remission, 6 very good partial remissions, 5 partial remissions, 2 patients with stable disease, and 5 with progressive disease. After the DLI phase, the response rate was 68%, but a significant upgrade of response was observed: 3 stringent complete remissions, 2 complete remissions, 5 very good partial remissions, 1 partial remission, 4 with stable disease, and 1 with progressive disease. With a median follow-up of 40 months (range, 29 to 68), the 3-year progression-free survival and overall survival rates were 31% and 73%, respectively. Neither unexpected organ toxicities, in particular severe neuropathy, nor severe acute graft-versus-host disease flares were observed. VD-DLIs is a safe treatment for multiple myeloma patients relapsing or progressing after alloSCT and may be effective. [Copyright &y& Elsevier]

Objectives The efficacy of a novel vaccine against influenza virus A ( H1 N1) in patients with hematologic malignancies is largely unknown. Methods We prospectively evaluated the humoral and cellular immune responses after one injection of monovalent adjuvanted 2009 H1 N1 vaccine in 47 adults with hematologic malignancies and 77 controls by hemagglutination-inhibition assay and flow-cytometry analysis on day 0, 28, 50, and 90. Results On day 28 postvaccination, patients had lower seroprotection (95.2% vs. 75.2%, P < 0.01) and seroconversion (88.7% vs. 51.1%, P < 0.01) rates, as well as geometric mean titer ( GMT; 256 vs. 134, P < 0.05), relative to controls. Response to vaccination varied according to the evaluated time point and the patient status: Patients not receiving chemotherapy had seroprotection and GMTs similar to controls in all time points, while patients receiving chemotherapy or allogeneic hematopoietic stem cell transplant ( HSCT) had lower seroprotection and seroconversion levels than controls on day 28 and 50. EMEA cutoffs for efficacy were reached from day 28 by patients in follow-up or under treatment and only from day 90 by those with HSCT, especially if still under immunosuppressants. Patients treated with immunomodulatory drugs had higher antibody responses in terms of seroprotection and GMTs. T- and NK cell-mediated responses mounted from day 50 and did not differ between patients and controls. Conclusions According to EMEA recommendation, H1 N1 vaccination strategy was effective at protecting most of the hematologic patients, but needed to be improved in those more immunocompromised.

Patients with therapy-related acute myeloid leukemia (t-AML) and myelodysplastic syndromes (t-MDS) have poor survival and high non-relapse mortality (NRM) after allogeneic stem cell transplantation. This retrospective study assessed the transplant outcomes of 29 consecutive patients with t-AML (83%) or t-MDS (17%) treated with allogeneic transplantation. The median age of patients was 51 years. Donors were mostly matched unrelated (52%), and 59% of patients received myeloablative conditioning. Two-year overall survival, event-free survival and relapse incidence were 37%, 34% and 33%; NRM was 17% at 100 days, and 32% at 2 years. Event-free survival was reduced in patients with high-risk cytogenetics ( p == 0.02), Karnofsky performance status ≤ 80% ( p == 0.001) and disease after induction ± consolidation ( p == 0.006). NRM was higher in patients receiving > 2 therapy lines for previous cancer ( p == 0.01) and in those allografted > 6 months from diagnosis ( p == 0.03). In conclusion, allogeneic transplantation should be proposed timely to these patients after an accurate analysis of patient history. [ABSTRACT FROM AUTHOR]

Evidence of long-term response to lenalidomide in heavily pretreated patients with multiple myeloma is lacking. This study sought to assess whether long-term responders exist, long-term responders' characteristics, and predictive factors of a long-term response. One hundred and four patients with multiple myeloma treated with lenalidomide and dexamethasone after ≥≥2 therapy lines (median, 3) were analyzed. Long-term response was defined as at least a partial response (≥≥PR) lasting ≥≥12 months. The overall response rate was 73%%, and 80.3%% of the responses were achieved within 5 months. The median response was 14.3 months. Patients evaluable for long-term response numbered 87, and a total of 47%% were long-term responders. Compared to non-long-term responders, long-term responders had better overall survival, less light-chain multiple myeloma, and higher incidence of t(11;14). Previous allogeneic transplant (alloSCT) and the response quality predicted a long-term response. In conclusion, patients treated with lenalidomide can become long-term responders; alloSCT and response quality predict long-term response. [ABSTRACT FROM AUTHOR]

In the frame of a circular economy, the maximization of secondary raw-material recovery is necessary to increase the economic and environmental sustainability of landfill mining and reclamation activities. In this paper, the polyethylene-rich plastic fraction recovered from the reclamation of an abandoned industrial landfill (landfill-recovered plastic, LRP) has been characterized through spectroscopic, thermal, morphological, and mechanical analyses. Then, an economically viable valorization and recycling strategy was set up. The effectiveness of this strategy in the enhancement of LRP properties has been demonstrated through morphological and mechanical characterizations. [ABSTRACT FROM AUTHOR]

The article discusses a court case wherein Perla Alimentare Srl, an Italy-based company involved in the industrial processing of honey, has been fined for having misled consumers about the main features of its product. The proceedings were launched upon notice by a customer who alerted the Italian Antitrust Authority of the alleged unfairness of the practice objected to. The authority asserts that the issue violated the Italian Consumer Code with regard to the product of the average consumer.

Patients with relapsed and refractory Hodgkin lymphoma (HL) may experience long-term survival after allogeneic stem cell transplantation (alloSCT), but disease recurrence represents the main cause of treatment failure. Positron-emission tomography (PET)–positive patients after alloSCT have a dismal outcome. Serum thymus and activation-regulated chemokine (TARC) is produced by Reed-Sternberg cells and may be a marker of disease. Our study aimed at assessing whether TARC levels after alloSCT correlated with disease status and whether TARC monitoring could increase the ability to predict relapse. Twenty-four patients were evaluated in a prospective observational study. TARC serum level and PET were assessed before and after alloSCT during the follow-up (median, 30 months; range, 2 to 54). Before alloSCT, the median TARC level was 721 pg/mL (range, 209 to 1332) in PET-negative patients and 2542 pg/mL (range, 94 to 13,870) in PET-positive patients. After alloSCT, TARC was 620 pg/mL (range, 12 to 4333) in persistently PET-negative patients compared with 22,397 pg/mL (range, 602 to 106,578) in PET-positive patients ( P < .0001). In 7 patients who relapsed after alloSCT, TARC level increased progressively even before PET became positive, with a median fold increase of 3.19 (range, 1.66 to 7.11) at relapse. The cut-off value of 1726 pg/mL had a sensitivity of 100% and a specificity of 71% for PET positivity. Patients with at least 1 TARC value above 1726 pg/mL during the first year after alloSCT had a worse progression-free survival ( P = .031). In conclusion, TARC was correlated with disease status and its monitoring may be able to predict PET positivity after alloSCT, thus potentially allowing an early immune manipulation.

Immunomodulatory drugs (IMiDs) may favor autoimmune disease (AD) occurrence. We conducted a retrospective study to evaluate AD occurrence among IMiD-treated patients with myeloma. Patients were grouped into three classes depending on the type of IMiD engaged. The first group included patients treated with thalidomide (Thal) ( n = 474), the second group with lenalidomide (Len) ( n = 140) and patients in the third group were first treated with Thal followed by Len (Thal-Len) ( n = 94). Absolute risk of AD was 0.4% for patients treated with Thal, 4.3% for Len and 1.1% for Thal-Len. ADs manifested prevalently as autoimmune cytopenias (55%), although we observed one vasculitis, one optic neuritis, one Graves' disease and one polymyositis. ADs occurred preferentially in the first months of IMiD treatment. A previous autologous transplant was shown to be a significant risk factor. All ADs were managed with IMiD discontinuation and steroids, resolving in a few weeks, except for Graves' disease and polymyositis. [ABSTRACT FROM AUTHOR]

Abstract: Cytomegalovirus (CMV) replication after allogeneic hematopoietic stem cell transplantation (HSCT) was historically associated with increased nonrelapse mortality (NRM). More recently, different groups have reported an association between CMV replication and reduced risk of acute myeloid leukemia (AML) relapse. Given the conflicting results, we evaluated the impact of CMV replication and other covariates on the outcome of a retrospective cohort of 265 adults with B cell lymphoma receiving allogeneic HSCT from HLA-identical siblings or alternative donors. In time-dependent multivariate analysis, CMV replication, evaluated by pp65 antigenemia, had no independent effect on the risk of relapse (hazard ratio [HR], 1.0; 95% confidence interval [CI], .6 to 1.6; P = .9), although it was associated with a reduced overall survival (HR, 2.0; 95% CI, 1.3 to 3.2; P = .001) and an increased NRM (HR, 2.5; 95% CI, 1.1 to 5.3; P = .01). Consistently, donor and/or recipient CMV seropositivity were not associated with a different outcome relative to CMV double-negative serostatus. In multivariate models, a diagnosis of follicular lymphoma (P < .0001) and pretransplantation complete remission status (P < .0001) were the main independent predictors for improved relapse-free survival. In summary, contrary to what is observed in patients with AML, this report identifies no independent role for CMV replication or serostatus on the relapse of patients with B cell lymphomas undergoing allogeneic HSCT.

Allogeneic stem cell transplantation (allo-SCT) using reduced-intensity conditioning (RIC) is a feasible procedure in selected patients with relapsed multiple myeloma (MM), but its efficacy remains a matter of debate. The mortality and morbidity related to the procedure and the rather high relapse risk make the use of allo-SCT controversial. In addition, the availability of novel antimyeloma treatments, such as bortezomib and immunomodulatory agents, have made allo-SCT less appealing to clinicians. We investigated the role of RIC allo-SCT in patients with MM who relapsed after autologous stem cell transplantation and were then treated with a salvage therapy based on novel agents. This study was structured similarly to an intention-to-treat analysis and included only those patients who underwent HLA typing immediately after the relapse. Patients with a donor (donor group) and those without a suitable donor (no-donor group) were compared. A total of 169 consecutive patients were evaluated retrospectively in a multicenter study. Of these, 75 patients found a donor and 68 (91%) underwent RIC allo-SCT, including 24 from an HLA-identical sibling (35%) and 44 from an unrelated donor (65%). Seven patients with a donor did not undergo allo-SCT for progressive disease or concomitant severe comorbidities. The 2-year cumulative incidence of nonrelapse mortality was 22% in the donor group and 1% in the no-donor group (P < .0001). The 2-year progression-free survival (PFS) was 42% in the donor group and 18% in the no-donor group (P < .0001). The 2-year overall survival (OS) was 54% in the donor group and 53% in the no-donor group (P = .329). In multivariate analysis, lack of a donor was a significant unfavorable factor for PFS, but not for OS. Lack of chemosensitivity after salvage treatment and high-risk karyotype at diagnosis significantly shortened OS. In patients who underwent allo-SCT, the development of chronic graft-versus-host disease had a significant protective effect on OS. This study provides evidence for a significant PFS benefit of salvage treatment with novel drugs followed by RIC allo-SCT in patients with relapsed MM who have a suitable donor.

Osteonecrosis of the jaw (ONJ) can be a severe complication of patients with multiple myeloma (MM) treated with bisphosphonates. Dental procedures are a major risk factor for ONJ occurrence. We retrospectively analysed the data of 178 patients with MM to evaluate if antibiotic prophylaxis before dental procedures may prevent ONJ. A correlation between dental procedures, antibiotic prophylaxis, incidence of ONJ and relevant clinical features was performed. Overall nine out of 178 patients developed ONJ (5 year crude cumulative incidence: 7.7%). Only one case of ONJ was not correlated with dental procedures. Seventy-five patients received at least one dental procedure and 43 received antibiotic prophylaxis. Eight cases of ONJ were observed, all in the group of patients without antibiotic prophylaxis. The only variable significantly associated with ONJ was antibiotic prophylaxis (p = 0.012), which had a protective effect. Thus, we speculated that antibiotic prophylaxis may prevent ONJ occurrence after dental procedures. [ABSTRACT FROM AUTHOR]

Chronic Myeloid Leukemia is a clonal disorder characterized by the presence of the Ph‐chromosome and the BCR‐ABL tyrosine‐kinase (TK). Target‐therapy with Imatinib has greatly improved its outcome. Deeper and faster responses are reported with the second‐generation TKI Nilotinib. Sustained responses may enable TKI discontinuation. However, even in a complete molecular response, some patients experience disease recurrence possibly due to persistence of quiescent leukemic CD34+/lin−Ph+ stem cells (LSCs). Degree and mechanisms of LSCs clearance during TKI treatment are not clearly established. The PhilosoPhi34 study was designed to verify the in‐vivo activity and timecourse of first‐line Nilotinib therapy on BM CD34+/lin−Ph+ cells clearance. Eighty‐seven CP‐CML patients were enrolled. BM cells were collected and tested for Ph+ residual cells, at diagnosis, 3, 6 and 12 months of treatment. FISH analysis of unstimulated CD34+/lin− cells in CCyR patients were positive in 8/65 (12.3%), 5/71 (7%), 0/69 (0%) evaluable tests, respectively. Per‐Protocol analysis response rates were as follows: CCyR 95% at 12 months, MR4.5 31% and 46% at 12 and 36 months, respectively. An exploratory Gene Expression Profiling (GEP) study of CD34+/lin− cells was performed on 30 patients at diagnosis and after, on 79 patients at diagnosis vs 12 months of nilotinib treatment vs 10 healthy subjects. Data demonstrated some genes significantly different expressed: NFKBIA, many cell cycle genes, ABC transporters, JAK‐STAT signaling pathway (JAK2). In addition, a correlation between different expression of some genes (JAK2, OLFM4, ICAM1, NFKBIA) among patients at diagnosis and their achievement of an early and deeper MR was observed.

• Definition of laboratory processes for high quality secondary plastic material. • MAPE was identified as an effective additive for properties enhancement. • Environmental analysis was conducted on industrial scale. • Environmental burdens of secondary plastic material production were assessed. • The secondary plastic material is more sustainable compared to a primary material. Enhanced Landfill Mining (ELFM) is a powerful tool for the sustainable management of landfill sites, aiming at both land reclamation and material recovery/reuse. To enhance the recovery and recycling rate of excavated plastic fractions, in most cases destined to energy recovery, new convenient, effective and sustainable strategies are needed. In this study, a recovery and valorization process of ELFM excavated plastics has been validated through an integrated experimental and Life Cycle Assessment (LCA) approach, demonstrating the environmental sustainability of the secondary raw material generated, in terms of use of resources and emissions generated. In particular, the secondary granulate from ELFM was compared with a virgin product and the last one resulted to have a higher impact (more than 4.46 times greater than the first one), in particular for the use of the resource crude oil as raw material in the production of primary LDPE. The valorization process of the excavated plastic made the mechanical properties of the secondary raw material comparable to that of a primary material. [ABSTRACT FROM AUTHOR]

Chronic myeloid leukemia (CML) is characterized by the constitutive tyrosine kinase activity of the oncoprotein BCR-ABL1 in myeloid progenitor cells that activates multiple signal transduction pathways leading to the leukemic phenotype. The tyrosine-kinase inhibitor (TKI) nilotinib inhibits the tyrosine kinase activity of BCR-ABL1 in CML patients. Despite the success of nilotinib treatment in patients with chronic-phase (CP) CML, a population of Philadelphia-positive (Ph+) quiescent stem cells escapes the drug activity and can lead to drug resistance. The molecular mechanism by which these quiescent cells remain insensitive is poorly understood. The aim of this study was to compare the gene expression profiling (GEP) of bone marrow (BM) CD34+/lin- cells from CP-CML patients at diagnosis and after 12 months of nilotinib treatment by microarray, in order to identify gene expression changes and the dysregulation of pathways due to nilotinib action. We selected BM CD34+/lin- cells from 78 CP-CML patients at diagnosis and after 12 months of first-line nilotinib therapy and microarray analysis was performed. GEP bioinformatic analyses identified 2,959 differently expressed probes and functional clustering determined some significantly enriched pathways between diagnosis and 12 months of nilotinib treatment. Among these pathways, we observed the under expression of 26 genes encoding proteins belonging to the cell cycle after 12 months of nilotinib treatment which led to the up-regulation of chromosome replication, cell proliferation, DNA replication, and DNA damage checkpoint at diagnosis. We demonstrated the under expression of the ATP-binding cassette (ABC) transporters ABCC4, ABCC5, and ABCD3 encoding proteins which pumped drugs out of the cells after 12 months of nilotinib. Moreover, GEP data demonstrated the deregulation of genes involved in the JAK-STAT signaling pathway. The down-regulation of JAK2, IL7, STAM, PIK3CA, PTPN11, RAF1, and SOS1 key genes after 12 months of nilotinib could demonstrate the up-regulation of cell cycle, proliferation and differentiation via MAPK and PI3K-AKT signaling pathways at diagnosis.

We report the long-term clinical outcomes of a retrospective multicenter study that enrolled 169 patients with multiple myeloma (MM) in first relapse after failing autologous stem cell transplantation (SCT). After HLA typing at relapse, 79 patients with a suitable donor, 72 (91%) of whom eventually underwent salvage allogeneic SCT (allo-SCT), were compared with 90 patients without a donor who were treated with multiple lines of salvage treatment with bortezomib and/or immunomodulatory agents. At a median follow-up of 30 months (range, 2-180 months) for all patients and 110 months (range, 38-180 months) for surviving patients, 7-year progression-free survival (PFS) was 18% in the donor group and 0% in the no-donor group (hazard ratio [HR], 2.495; 95% confidence interval [CI], 1.770-3.517; P  < .0001). Seven-year overall survival (OS) was 31% in the donor group and 9% in the no-donor group (HR, 1.835; 95% CI, 1.306-2.577; P  < .0001). By multivariate analysis, chemosensitivity to salvage treatments and presence of a suitable donor were significantly associated with better PFS and OS. The long-term follow-up of this study confirms the significant PFS benefit and provides new evidence of an OS advantage for patients with MM who have a suitable donor and undergo allo-SCT. Allo-SCT should be considered as a treatment option in young relapsed patients with high-risk disease features after first-line treatment. [ABSTRACT FROM AUTHOR]

BACKGROUND: Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder with heterogeneous biological and clinical features. The biomolecular mechanisms of CML response to tyrosine-kinase inhibitors are not fully defined. OBJECTIVE: We undertook a gene expression profiling (GEP) study of selected bone marrow (BM) CD34+/lin- cells of chronic-phase CML patients at diagnosis and after 12 months of TKI nilotinib to investigate molecular signatures characterizing both conditions. METHODS:We selected and counted BM CD34+/lin- cells of 30 CML patients at diagnosis and during 3, 6 and 12 months of first-line nilotinib treatment. GEP was performed between CD34+/lin- cells of patients at diagnosis and the same patients after 12 months of nilotinib. RESULTS: The number of BM CD34+/lin- cells dramatically decreased after 3, 6 and 12 months of nilotinib. GEP detected 264 statistically significant differentially expressed genes at diagnosis vs. 12 months of nilotinib. Functional enrichment analysis revealed groups of genes belonging to 14 pathways differentially active during nilotinib treatment. CONCLUSIONS: In conclusion, lipid, glucose and sphingolipid metabolism, insulin resistance, complement and coagulation, platelet activation, cytoscheleton, cell adhesion, transport, B cell differentiation, RAS-signaling pathway, proliferation, growth factors, and apoptosis were significantly deregulated between CML patients at diagnosis and after 12 months of nilotinib.

Simple Summary: The BRAFV600E mutation accounts for 8–10% of metastatic colorectal cancer (mCRC) patients and it is an established prognostic factor. Median overall survival of this subset of patients is indeed so poor that it is similar to first line PFS of patients without this molecular alteration. An exception is represented by patients displaying concomitant MSI-H status who can benefit from immunotherapy with checkpoint inhibitors (CPIs). Recently, a targeted therapy with the combination of encorafenib and cetuximab provided for the first time a survival gain and thus translation in the clinic, even though acquired resistance limits the possibility of more than an incremental benefit. Many studies exploiting other different strategies are ongoing. In this review we present current therapies specifically headed to BRAFV600E mutant mCRC and systematically review ongoing clinical trials identifying different approaches under investigations: targeting MAPK pathway (monotherapy or combinations), targeting MAPK pathway combined with cytotoxic agents, intensive cytotoxic regimen combinations, targeted agents combined with CPIs, oxidative stress induction, and cytotoxic agents combined with antiangiogenic drugs and CPIs. The BRAFV600E mutation is found in 8–10% of metastatic colorectal cancer (mCRC) patients and it is recognized as a poor prognostic factor with a median overall survival inferior to 20 months. At present, besides immune checkpoint inhibitors (CPIs) for those tumors with concomitant MSI-H status, recommended treatment options include cytotoxic chemotherapy + anti-VEGF in the first line setting, and a combination of EGFR and a BRAF inhibitor (cetuximab plus encorafenib) in second line. However, even with the latter targeted approach, acquired resistance limits the possibility of more than an incremental benefit and survival is still dismal. In this review, we discuss current treatment options for this subset of patients and perform a systematic review of ongoing clinical trials. Overall, we identified six emerging strategies: targeting MAPK pathway (monotherapy or combinations), targeting MAPK pathway combined with cytotoxic agents, intensive cytotoxic regimen combinations, targeted agents combined with CPIs, oxidative stress induction, and cytotoxic agents combined with antiangiogenic drugs and CPIs. In the future, the integration of new therapeutic strategies targeting key players in the BRAFV600E oncogenic pathways with current treatment approach based on cytotoxic chemotherapy and surgery is likely to redefine the treatment landscape of these CRC patients.
