Prognostic characterization of copper death-related immune checkpoint genes and analysis of immunologic and pharmacologic therapy in bladder cancer

Objective:Copper death-induced tumor cell death and immune checkpoint blockade therapy are highly selective.Combining their advantages and understanding their characteristics in bladder cancer is very important for the development of new targeted therapy.The identification of bladder cancer by screening the characteristic genes of copper death-related immune checkpoints provide a theoretical basis for the selection of adjuvant treatment options and the application of new targets.Methods:The expression samples of normal bladder tissue and bladder cancer were obtained from TCGA and GEO databases,and 13 cop-per death genes and 79 immune checkpoint genes were extracted from previous studies.The mRNA expression of prognostic genes was verified by qPCR.The copper death-related immune checkpoint genes were screened by correlation analysis to construct a prognostic model,and the differences in the efficacy of immunotherapy and chemotherapy between the high-risk group and the low-risk group were evaluated.Results:A prognostic model consisting of BTNL9,CD160,TNFRSF14 and TNFRSF18 was constructed.Its reliable predictive ability was proved in both databases,and qPCR showed that the expression levels of the four genes were significantly different between the normal group and the cancer cell group.The effect of immunotherapy in the lowrisk group was better than that in the high-risk group.Patients in the high-risk group had better chemotherapy efficacy.Conclusion:The copper death-related immune checkpoint gene model can accurately predict the prognosis of patients.Drug and immune analysis provide a basis for clinical treatment,and the discovery of potential targets provides a new solution for clinical decision-making.

Efficacy evaluation and survival analysis of the combination of oxaliplatin plus Teysuno (SOX) with immune checkpoint inhibitors in the conversion therapy of locally advanced gastric cancer

Background:The efficacy of combining immune checkpoint inhibitors(ICIs)with chemotherapy in neoadjuvant therapy for locally advanced gastric cancer has been explored.However,limited research exists on its effectiveness in conversion therapy,and its superiority over standalone chemotherapy remains to be elucidated.This study aims to investigate the efficacy and survival outcomes of patients treated with ICIs in combination with conversion therapy for locally advanced gastric cancer.Methods:Retrospective data from patients with locally advanced gastric cancer treated with either oxaliplatin+S-1(SOX)alone or in combination with ICIs in conversion therapywere collected.Clinical andpathological characteristics,disease-free survival,andefficacy assessments in nonoperable patients were compared between the 2 treatment groups.Efficacy was further evaluated through dynamic changes in serum markers,and patients’quality of life was assessed using the QLQ-STO22(Gastric Cancer–Specific Quality of Life Questionnaire)quality-of-life measurement scale.Results:A total of 140 patients underwent conversion therapy:80 in the SOX alone group and 60 in the SOX combined with the ICIs group.There were no significant differences in baseline characteristics between the 2 groups.Compared with the SOX alone group,the SOX combined with ICIs group exhibited a higher conversion rate(83.3%vs 75%,P=0.23),R0 resection rate(90.0%vs 83.3%,P=0.31),pathological complete response(pCR)rate(18%vs 5%,P=0.02),median disease-free survival(21.4 vs 16.9 months,P=0.007),the objective response rate in nonoperable patients(60%vs 40%,P=0.301),and median progression-free survival time(7.9 vs 5.7 months,P=0.009).The QLQ-STO22 quality-of-life assessment revealed statistically significant improvements in pain,swallowing difficulties,and dietary restrictions in the combination therapy group compared with those in the monotherapy group.The enhanced efficacy of immune combination with SOX is evident,as demonstrated by the significantly prolonged surgical duration in operated patients(206.6±26.6 min vs 197.8±19.8 min,P=0.35)and intraoperative blood loss(158.9±21.2 mL vs 148.9±25.1 mL,P=0.59).No significant differences were observed in postoperative complications.Conclusions:Compared with the SOX conversion therapy regimen,SOX combined with ICIs demonstrated higher conversion rates,R0 resection rates,pathological response rates,and disease-free survival without increasing surgical difficulty or complications.Nonoperable patients also experienced longer progression-free survival and objective response rates.

Opportunities and challenges of CD47-targeted therapy in cancer immunotherapy

Cancer immunotherapy has emerged as a promising strategy for the treatment of cancer,with the tumor microenvironment(TME)playing a pivotal role in modulating the immune response.CD47,a cell surface protein,has been identified as a crucial regulator of the TME and a potential therapeutic target for cancer therapy.However,the precise functions and implications of CD47 in the TME during immunotherapy for cancer patients remain incompletely understood.This comprehensive review aims to provide an overview of CD47’s multifaced role in TME regulation and immune evasion,elucidating its impact on various types of immunotherapy outcomes,including checkpoint inhibitors and CAR T-cell therapy.Notably,CD47-targeted therapies offer a promising avenue for improving cancer treatment outcomes,especially when combined with other immunotherapeutic approaches.The review also discusses current and potential CD47-targeted therapies being explored for cancer treatment and delves into the associated challenges and opportunities inherent in targeting CD47.Despite the demonstrated effectiveness of CD47-targeted therapies,there are potential problems,including unintended effects on healthy cells,hematological toxicities,and the development if resistance.Consequently,further research efforts are warranted to fully understand the underlying mechanisms of resistance and to optimize CD47-targeted therapies through innovative combination approaches,ultimately improving cancer treatment outcomes.Overall,this comprehensive review highlights the significance of CD47 as a promising target for cancer immunotherapy and provides valuable insight into the challenges and opportunities in developing effective CD47-targeted therapies for cancer treatment.

Immunotherapy for esophageal cancer:Where are we now and where can we go

Immune checkpoint inhibitor therapy has dramatically improved patient prognosis,and thereby transformed the treatment in various cancer types including esophageal squamous cell carcinoma(ESCC)in the past decade.Monoclonal antibodies that selectively inhibit programmed cell death-1(PD-1)activity has now become standard of care in the treatment of ESCC in metastatic settings,and has a high expectation to provide clinical benefit during perioperative period.Further,anti-cytotoxic T-lymphocyte–associated protein 4(CTLA-4)monoclonal antibody has also been approved in the treatment of recurrent/metastatic ESCC in combination with anti-PD-1 antibody.Well understanding of the existing evidence of immune-based treatments for ESCC,as well as recent clinical trials on various combinations with chemotherapy for different clinical settings including neoadjuvant,adjuvant,and metastatic diseases,may provide future prospects of ESCC treatment for better patient outcomes.

Immune status and combined immunotherapy progression in Kirsten rat sarcoma viral oncogene homolog(KRAS)-mutant tumors

Kirsten rat sarcoma viral oncogene homolog(KRAS)is the most frequently mutated oncogene,occurring in various tumor types.Despite extensive efforts over the past 40 years to develop inhibitors targeting KRAS mutations,resistance to these inhibitors has eventually emerged.A more precise understanding of KRAS mutations and the mechanism of resistance development is essential for creating novel inhibitors that target specifically KRAS mutations and can delay or overcome resistance.Immunotherapy has developed rapidly in recent years,and in-depth dissection of the tumor immune microenvironment has led researchers to shift their focus to patients with KRAS mutations,finding that immune factors play an essential role in KRAS-mutant(KRAS-Mut)tumor therapy and targeted drug resistance.Breakthroughs and transitions from targeted therapy to immunotherapy have provided new hope for treating refractory patients.Here,we reviewed KRAS mutation-targeted treatment strategies and resistance issues,focusing on our in-depth exploration of the specific immune status of patients with KRAS mutations and the impact of body immunity following KRAS inhibition.We aimed to guide innovative approaches combining RAS inhibition with immunotherapy,review advances in preclinical and clinical stages,and discuss challenges and future directions.

NIR-triggered on-site NO/ROS/RNS nanoreactor:Cascade-amplified photodynamic/photothermal therapy with local and systemic immune responses activation

Photothermal and photodynamic therapies(PTT/PDT)hold promise for localized tumor treatment,yet their full potential is hampered by limitations such as the hypoxic tumor microenvironment and inadequate systemic immune activation.Addressing these challenges,we present a novel near-infrared(NIR)-triggered RNS nanoreactor(PBNO-Ce6)to amplify the photodynamic and photothermal therapy efficacy against triple-negative breast cancer(TNBC).The designed PBNOCe6 combines sodium nitroprusside-doped Prussian Blue nanoparticles with Chlorin e6 to enable on-site RNS production through NIR-induced concurrent NO release and ROS generation.This not only enhances tumor cell eradication but also potentiates local and systemic antitumor immune responses,protecting mice from tumor rechallenge.Our in vivo evaluations revealed that treatment with PBNO-Ce6 leads to a remarkable 2.7-fold increase in cytotoxic T lymphocytes and a 62%decrease in regulatory T cells in comparison to the control PB-Ce6(Prussian Blue nanoparticles loaded with Chlorin e6),marking a substantial improvement over traditional PTT/PDT.As such,the PBNO-Ce6 nanoreactor represents a transformative approach for improving outcomes in TNBC and potentially other malignancies affected by similar barriers.

DNA Damage-driven Inflammatory Cytokines:Reprogramming of Tumor Immune Microenvironment and Application of Oncotherapy

DNA damage occurs across tumorigenesis and tumor development.Tumor intrinsic DNA damage can not only increase the risk of mutations responsible for tumor generation but also initiate a cellular stress response to orchestrate the tumor immune microenvironment(TIME)and dominate tumor progression.Accumulating evidence documents that multiple signaling pathways,including cyclic GMP-AMP synthase-stimulator of interferon genes(cGAS-STING)and ataxia telangiectasia-mutated protein/ataxia telangiectasia and Rad3-related protein(ATM/ATR),are activated downstream of DNA damage and they are associated with the secretion of diverse cytokines.These cytokines possess multifaced functions in the anti-tumor immune response.Thus,it is necessary to deeply interpret the complex TIME reshaped by damaged DNA and tumor-derived cytokines,critical for the development of effective tumor therapies.This manuscript comprehensively reviews the relationship between the DNA damage response and related cytokines in tumors and depicts the dual immunoregulatory roles of these cytokines.We also summarize clinical trials targeting signaling pathways and cytokines associated with DNA damage and provide future perspectives on emerging technologies.

Approaches and challenges in cancer immunotherapy pathways

Cancer immunotherapy is an effective with critical approaches in the treatment of oncological patients.Whilst numerous research and clinical trials are underway to develop endogenous immunotherapy approaches,it is necessary to focus on fundamental issues and identify barriers to basic clinical progress.Addressing these challenges and the new pathways will require researchers and clinicians to join forces to accelerate the understanding of the complex interactions between cancer and the immune system and focus resources on developing better treatments for patients.

Progress of Immunotherapy Combined with Anti-Angiogenesis Therapy in Lung Cancer

Lung cancer is the most prevalent and fatal cancer in China and even around the world, and many patients are found in the late stage of lung cancer. For the treatment of advanced lung cancer, in addition to traditional chemotherapy modalities, many emerging treatments are increasingly significant, such as immunotherapy, anti-angiogenic therapy, and targeted therapy. An increasing number of studies have now shown that anti-angiogenic therapy improves the immune microenvironment by enhancing tumor immunity through normalization of tumor vessels. Immunization combined with anti-angiogenic therapy can exert synergistic effects and improve the prognosis of patients. This article summarizes the extent of benefit, current clinical study data, and future prospects of immunotherapy combined with anti-angiogenic agents in the treatment of advanced NSCLC.

Effect of Stereotactic Body Radiation Therapy on Diverse Organ Lesions in Advanced Non-Small Cell Lung Cancer Patients Receiving Immune Checkpoint Inhibitors

Objective The combination of stereotactic body radiation therapy(SBRT)and immune checkpoint inhibitors(ICIs)is actively being explored in advanced non-small-cell lung cancer(NSCLC)patients.However,little is known about the optimal fractionation and radiotherapy target lesions in this scenario.This study investigated the effect of SBRT on diverse organ lesions and radiotherapy dose fractionation regimens on the prognosis of advanced NSCLC patients receiving ICIs.Methods The medical records of advanced NSCLC patients consecutively treated with ICIs and SBRT were retrospectively reviewed at our institution from Dec.2015 to Sep.2021.Patients were grouped according to radiation sites.Progression-free survival(PFS)and overall survival(OS)were recorded using the Kaplan-Meier method and compared between different treatment groups using the log-rank(Mantel-Cox)test.Results A total of 124 advanced NSCLC patients receiving ICIs combined with SBRT were identified in this study.Radiation sites included lung lesions(lung group,n=43),bone metastases(bone group,n=24),and brain metastases(brain group,n=57).Compared with the brain group,the mean PFS(mPFS)in the lung group was significantly prolonged by 13.3 months(8.5 months vs.21.8 months,HR=0.51,95%CI:0.28–0.92,P=0.0195),and that in the bone group prolonged by 9.5 months with a 43%reduction in the risk of disease progression(8.5 months vs.18.0 months,HR=0.57,95%CI:0.29–1.13,P=0.1095).The mPFS in the lung group was prolonged by 3.8 months as compared with that in the bone group.The mean OS(mOS)in the lung and bone groups was longer than that of the brain group,and the risk of death decreased by up to 60%in the lung and bone groups as compared with that of the brain group.When SBRT was concurrently given with ICIs,the mPFS in the lung and brain groups were significantly longer than that of the bone group(29.6 months vs.16.5 months vs.12.1 months).When SBRT with 8–12 Gy per fraction was combined with ICIs,the mPFS in the lung group was significantly prolonged as compared with that of the bone and brain groups(25.4 months vs.15.2 months vs.12.0 months).Among patients receiving SBRT on lung lesions and brain metastases,the mPFS in the concurrent group was longer than that of the SBRT→ICIs group(29.6 months vs.11.4 months,P=0.0003 and 12.1 months vs.8.9 months,P=0.2559).Among patients receiving SBRT with<8 Gy and 8–12 Gy per fraction,the mPFS in the concurrent group was also longer than that of the SBRT→ICIs group(20.1 months vs.5.3 months,P=0.0033 and 24.0 months vs.13.4 months,P=0.1311).The disease control rates of the lung,bone,and brain groups were 90.7%,83.3%,and 70.1%,respectively.Conclusion The study demonstrated that the addition of SBRT on lung lesions versus bone and brain metastases to ICIs improved the prognosis in advanced NSCLC patients.This improvement was related to the sequence of radiotherapy combined with ICIs and the radiotherapy fractionation regimens.Dose fractionation regimens of 8–12 Gy per fraction and lung lesions as radiotherapy targets might be the appropriate choice for advanced NSCLC patients receiving ICIs combined with SBRT.

The progress of combination therapy with immune checkpoint inhibitors in breast cancer

Immunotherapy targets the dysfunctional immune system to induce cancer cell killing by CD8-positive T cells.Immune checkpoint inhibitors(ICIs),specifically anti-PD-1 antibodies,anti-PD-L1 antibodies,and anti-CTLA4 antibodies,have revolutionized the management of many malignancies due to their significant role in generating a durable clinical response.However,clinical data suggest that response rates to ICI monotherapy are low due to the immunologically silent characteristics of breast cancer(BC).Chemotherapy,surgery,radiotherapy,and targeted therapy were recently reported to alter the tumor microenvironment and enhance the ICI response.Some clinical studies supported that ICIs,in combination with other treatment strategies,show superior efficacy in BC control,especially triple-negative breast cancer.Therefore,seeking a reasonable combination therapy is a promising way to improve ICI response.The present review highlights the clinical efficacy of ICIs treatment options in combination with standard-of-care therapies,such as chemotherapy and targeted therapy。

The Effect of TSH Suppression Therapy on the Efficacy and Immune Function of Postoperative Patients with Thyroid Cancer

Objective:To investigate the efficacy and immune function of thyroid stimulating hormone(TSH)suppression therapy in postoperative thyroid cancer patients.Methods:Sixty thyroid cancer patients admitted from July 2020–July 2022 were recruited and randomly divided into two groups.The control group(30 patients)received hormone replacement therapy,while the study group(30 patients)received TSH suppression therapy.The thyroid function,clinical efficacy,immune function,and tumor markers of the two groups were compared.Results:After treatment,the levels of free triiodothyronine(FT3)and thyroxine(FT4)in both groups increased significantly,while TSH levels decreased significantly.Moreover,the magnitude of change in the study group was greater than that in the control group(P<0.05).The total effective rate in the study group was significantly higher as compared to the control group(P<0.05).After treatment,the levels of CD3+and CD4+cells in both groups of patients increased significantly,with the study group showing significantly higher levels than the control group,whereas the level of CD8+cells decreased significantly,with the study group having lower levels than the control group(P<0.05).After treatment,the levels of Tg and CEA in both groups were significantly lowered as compared to before treatment,and the levels of Tg and CEA in the study group were significantly lower than the control group(P<0.05).Conclusion:TSH suppression therapy in postoperative thyroid cancer patients can improve thyroid function,suppress the levels of tumor markers,and enhance immune function,thereby achieving good clinical outcomes.

Challenges and exploration for immunotherapies targeting cold colorectal cancer

In recent years,immune checkpoint inhibitors(ICIs)have made significant breakthroughs in the treatment of various tumors,greatly improving clinical efficacy.As the fifth most common antitumor treatment strategy for patients with solid tumors after surgery,chemotherapy,radiotherapy and targeted therapy,the therapeutic response to ICIs largely depends on the number and spatial distribution of effector T cells that can effectively identify and kill tumor cells,features that are also important when distinguishing malignant tumors from“cold tumors”or“hot tumors”.At present,only a small proportion of colorectal cancer(CRC)patients with deficient mismatch repair(dMMR)or who are microsatellite instability-high(MSI-H)can benefit from ICI treatments because these patients have the characteristics of a“hot tumor”,with a high tumor mutational burden(TMB)and massive immune cell infiltration,making the tumor more easily recognized by the immune system.In contrast,a majority of CRC patients with proficient MMR(pMMR)or who are microsatellite stable(MSS)have a low TMB,lack immune cell infiltration,and have almost no response to immune monotherapy;thus,these tumors are“cold”.The greatest challenge today is how to improve the immunotherapy response of“cold tumor”patients.With the development of clinical research,immunotherapies combined with other treatment strategies(such as targeted therapy,chemotherapy,and radiotherapy)have now become potentially effective clinical strategies and research hotspots.Therefore,the question of how to promote the transformation of“cold tumors”to“hot tumors”and break through the bottleneck of immunotherapy for cold tumors in CRC patients urgently requires consideration.Only by developing an in-depth understanding of the immunotherapy mechanisms of cold CRCs can we screen out the immunotherapy-dominant groups and explore the most suitable treatment options for individuals to improve therapeutic efficacy.

Research progress on immune checkpoint inhibitors in neoadjuvant therapy for gastric cancer

In recent years,immune checkpoint inhibitors(ICIs)have become an important treatment strategy for advanced gastric cancer.Immunotherapy has gradually transitioned from a later-line to a first-line treatment for advanced gastric cancer.Simultaneously,more and more researchers have begun to pay attention to whether immunotherapy can be used for resectable gastric cancer.The current use of ICIs in the neoadjuvant treatment of gastric cancer is still in its exploratory stage,with a number of clinical trials currently underway.However,the available data show good application prospects.This article reviews the research progress on ICIs in the neoadjuvant therapy for gastric cancer and evokes some unresolved problems.

Immunotherapy for hepatocellular carcinoma:Current status and future perspectives

Hepatocellular carcinoma(HCC)is one of the world’s deadliest and fastestgrowing tumors,with a poor prognosis.HCC develops in the context of chronic liver disease.Curative resection,surgery(liver transplantation),trans-arterial chemoembolization,radioembolization,radiofrequency ablation and chemotherapy are common treatment options for HCC,however,they will only assist a limited percentage of patients.Current treatments for advanced HCC are ineffective and aggravate the underlying liver condition.Despite promising preclinical and early-phase clinical trials for some drugs,existing systemic therapeutic methods for advanced tumor stages remain limited,underlining an unmet clinical need.In current years,cancer immunotherapy has made significant progress,opening up new treatment options for HCC.HCC,on the other hand,has a variety of causes and can affects the body’s immune system via a variety of mechanisms.With the speedy advancement of synthetic biology and genetic engineering,a range of innovative immunotherapies,such as immune checkpoint inhibitors[anti-programmed cell death-1(PD-1),anti-cytotoxic T lymphocyte antigen-4,and anti-PD ligand 1 cell death antibodies],therapeutic cancer vaccines,engineered cytokines,and adoptive cell therapy have all been used for the treatment of advanced HCC.In this review,we summarize the present clinical and preclinical landscape of immunotherapies in HCC,critically discuss recent clinical trial outcomes,and address future perspectives in the field of liver cancer.

Immunotherapy in gastric cancer

Gastric cancer is the second most common of cancerrelated deaths worldwide.In the majority of cases gastric cancer is advanced at diagnosis and although medical and surgical treatments have improved,survival rates remain poor.Cancer immunotherapy has emerged as a powerful and promising clinical approach for treatment of cancer and has shown major success in breast cancer,prostate cancer and melanoma.Here,we provide an overview of concepts of modern cancer immunotherapy including the theory,current approaches,remaining hurdles to be overcome,and the future prospect of cancer immunotherapy in the treatment of gastric cancer.Adaptive cell therapies,cancer vaccines,gene therapies,monoclonal antibody therapies have all been used with some initial successes in gastric cancer.However,to date the results in gastric cancer have been disappointing as current approaches often do not stimulate immunity efficiently allowing tumors continue to grow despite the presence of a measurable immune response.Here,we discuss the identification of targets for immunotherapy and the role of biomarkers in prospectively identifying appropriate subjects or immunotherapy.We also discuss the molecular mechanisms by which tumor cells escape host immunosurveillance and produce an immunosuppressive tumor microenvironment.We show how advances have provided tools for overcoming the mechanisms of immunosuppression including the use of monoclonal antibodies to block negative regulators normally expressed on the surface of T cells which limit activation and proliferation of cytotoxic T cells.Immunotherapy has greatly improved and is becoming an important factor in such fields as medical care and welfare for human being.Progress has been rapid ensuring that the future of immunotherapy for gastric cancer is bright.

Aiming to immune elimination of ovarian cancer stem cells

Ovarian cancer accounts for only 3% of all cancers in women, but it causes more deaths than any other gynecologic cancer. Treatment with chemotherapy and cytoreductive surgery shows a good response to the therapy. However, in a large proportion of the patients the tumor grows back within a few years. Cancer stem cells, that are less responsive to these treatments, are blamed for this recurrence of disease. Immune therapy either cellular or humoral is a novel concept to treat cancer. It is based on the notice that immune cells invade the tumor. However, the tumor invest heavily to escape from immune elimination by recruiting several immune suppressive mechanisms. These processes are normally in place to limit excessive immune activation and prevent autoimmune phenomena. Here, we discuss current knowledge about the immune(suppressive)status in ovarian cancer. Moreover, we discuss the immunological targets of ovarian cancer stem cells.

Immunological battlefield in gastric cancer and role of immunotherapies

Like the wars predating the First World War where human foot soldiers were deemed tools in the battlefield against an enemy, so too are the host immune cells of a patient battling a malignant gastric cancer. Indeed, the tumour microenvironment resembles a battlefield, where the patient's immune cells are the defence against invading tumour cells. However, the relationship between different immune components of the host response to cancer is more complex than an "us against them" model. Components of the immune system inadvertently work against the interests of the host and become pro-tumourigenic while other components soldier on against the common enemy – the tumour cell.

Immunotherapy in human colorectal cancer: challenges and prospective

Human colorectal cancer(CRC) is the third most commonly diagnosed malignancies and the prognosis for patients with recurrent or metastatic disease is extremely poor. Although new chemotherapeutic regimen improves survival rates, therapy with better efficacy and less adverse effects is drastically needed. Immunotherapy has been investigated in human CRC for decades with limited success. However, recent developments of immunotherapy, particularly immune checkpoint inhibitor therapy, have achieved promising clinical benefits in many types of cancer and revived the hope for utilizing such therapy in human CRC. In this review, we will discuss important immunological landscape within the CRC microenvironment and introduce immunoscore system to better describe immunophenotyping in CRC. We will also discuss different immunotherapeutic approaches currently utilized in different phases of clinical trials. Some of those completed or ongoing trials are summarized. Finally, we provide a brief prospective on the future human CRC immunotherapy.

Personalized immunotherapy in cancer precision medicine

With the significant advances in cancer genomics using next-generation sequencing technologies,genomic and molecular profilingbased precision medicine is used as a part of routine clinical test for guiding and selecting the most appropriate treatments for individual cancer patients.Although many molecular-targeted therapies for a number of actionable genomic alterations have been developed,the clinical application of such information is still limited to a small proportion of cancer patients.In this review,we summarize the current status of personalized drug selection based on genomic and molecular profiling and highlight the challenges how we can further utilize the individual genomic information.Cancer immunotherapies,including immune checkpoint inhibitors,would be one of the potential approaches to apply the results of genomic sequencing most effectively.Highly cancer-specific antigens derived from somatic mutations,the so-called neoantigens,occurring in individual cancers have been in focus recently.Cancer immunotherapies,which target neoantigens,could lead to a precise treatment for cancer patients,despite the challenge in accurately predicting neoantigens that can induce cytotoxic T cells in individual patients.Precise prediction of neoantigens should accelerate the development of personalized immunotherapy including cancer vaccines and T-cell receptor-engineered T-cell therapy for a broader range of cancer patients.
