RESUMO

BACKGROUND: Many cancer patients experience malnutrition, which can worsen their health and survival outcomes. However, limited research exists in our region on how common malnutrition is among hospitalized adults with solid tumors and what factors contribute to it. This study aimed to identify these factors and assess the effects of nutritional impact symptoms (NISs) caused by solid tumors on patients' nutritional status. METHODS: Between July 2022 and February 2023, a cross-sectional study was carried out on the campuses of two major cancer treatment centers located in a national university hospital and a governmental hospital. Twelve NISs were adopted from the Patient-Generated Subjective Global Assessments (PG-SGA). The Nutrition Risk Screening 2002 (NRS-2002) instrument was used to thoroughly assess the risk of malnutrition. Multiple linear regressions were used to conduct a thorough study. RESULTS: A cohort of 294 participants was included. The prevalence of malnutrition risk (NRS score ≥ 3) was 26.9%. Parameters such as age, gender, marital status, educational level, monthly income, type of cancer and treatment modality, and the need for mealtime assistance exhibited statistically significant associations with malnutrition (p < 0.05). The results revealed a substantial inverse correlation between fluid intake and the NRS-2002 score (p < 0.001). Furthermore, symptoms related to solid tumors and their treatment, including chewing difficulties, fatigue, dry mouth, anorexia, constipation, nausea, dizziness, and a sensation of fullness, were also significantly associated with malnutrition (p < 0.05). Additional insights from the regression analysis underscored the independent correlation between the risk of malnutrition in solid malignant malignancies and factors such as anorexia (p < 0.001), colorectal cancer (p = 0.003), gender (p = 0.018), educational attainment (p = 0.049), and the need for mealtime assistance among patients (p < 0.001). CONCLUSIONS: Malnutrition is a major issue among adult cancer patients, particularly those with solid tumors. Anorexia, colorectal cancer, gender, educational attainment, and the need for mealtime assistance were identified as factors that led to malnutrition in our research. This study emphasizes the need for a multidisciplinary plan of care to diagnose and treat malnutrition, improve overall therapy, and reduce mortality and morbidity.

RESUMO

Peritumoral fibrosis is known to promote cancer progression and confer treatment resistance in various solid tumors. Consequently, developing accurate cancer research and drug screening models that replicate the structure and function of a fibrosis-surrounded tumor mass is imperative. Previous studies have shown that self-assembly three-dimensional (3D) co-cultures primarily produce cancer-encapsulated fibrosis or maintain a fibrosis-encapsulated tumor mass for a short period, which is inadequate to replicate the function of fibrosis, particularly as a physical barrier. To address this limitation, a multi-layer spheroid formation method is developed to create a fibrosis-encapsulated tumoroid (FET) structure that maintains structural stability for up to 14 days. FETs exhibited faster tumor growth, higher expression of immunosuppressive cytokines, and equal or greater resistance to anticancer drugs compared to their parental tumoroids. Additionally, FETs serve as a versatile model for traditional cancer research, enabling the study of exosomal miRNA and gene functions, as well as for mechanobiology research when combined with alginate hydrogel. Our findings suggest that the FET represents an advanced model that more accurately mimics solid cancer tissue with peritumoral fibrosis. It may show potential superiority over self-assembly-based 3D co-cultures for cancer research and drug screening, and holds promise for personalized drug selection in cancer treatment.

RESUMO

BACKGROUND: Lactate dehydrogenase (LDH) is involved in the Warburg effect. Elevated serum LDH is a prognostic marker for metastatic solid cancer. AIM: To investigate the prognostic impact of serum LDH in patients with head and neck squamous cell carcinoma treated with immune checkpoint inhibitors (ICIs). MATERIALS AND METHODS: This retrospective study included 129 patients treated with ICIs between 2017 and 2023. The effects of pretreatment LDH, LDH at 3 months, and change in LDH during the first 3 months (ΔLDH) on overall survival (OS) and progression-free survival (PFS) were analyzed using the Kaplan-Meier method and Cox regression model. RESULTS: The 1-year PFS and OS rates for high and low groups were 6.0% and 30.1% for pretreatment LDH (p = 0.044), 25.7% and 38.3% for on-treatment LDH (p = 0.079), and 14.3% and 38.7% for ΔLDH (p = 0.008), as well as 42.1% and 60.9% for pretreatment LDH (p = 0.109), 56.0% and 80.5% (p < 0.001) for on-treatment LDH, and 31.0% and 81.0% for ΔLDH (p < 0.001), respectively. ΔLDH was an independent prognostic factor for both PFS and OS. CONCLUSIONS AND SIGNIFICANCE: ΔLDH can be used to predict ICI treatment outcomes and as a marker in deciding to continue ICI therapy.

RESUMO

The study aimed to describe the epidemiology of multidrug-resistant (MDR) bacteria among solid cancer (SC) patients with bloodstream infections (BSIs), evaluating inappropriate empiric antibiotic treatment (IEAT) use and mortality trends over a 25-year period. All BSI occurrences in adult SC patients at a university hospital were analyzed across five distinct five-year intervals. MDR bacteria were classified as extended-spectrum beta-lactamases (ESBL)-producing and/or Carbapenem-resistant Enterobacterales, non-fermenting Gram-negative bacilli (GNB) resistant to at least three antibiotic classes, methicillin-resistant Staphylococcus aureus (MRSA), and Vancomycin-resistant Enterococci. A multivariate regression model identified the risk factors for MDR BSI. Of 6,117 BSI episodes, Gram-negative bacilli (GNB) constituted 60.4% (3,695/6,117), being the most common are Escherichia coli with 26.8% (1,637/6,117), Klebsiella spp. with 12.4% (760/6,117), and Pseudomonas aeruginosa with 8.6% (525/6,117). MDR-GNB accounted for 644 episodes (84.8% of MDR or 644/759), predominantly ESBL-producing strains (71.1% or 540/759), which escalated significantly over time. IEAT was administered in 24.8% of episodes, mainly in MDR BSI, and was associated with higher mortality (22.9% vs. 14%, P < 0.001). Independent factors for MDR BSI were prior antibiotic use [odds ratio (OR) 2.93, confidence interval (CI) 2.34-3.67], BSI during antibiotic treatment (OR 1.46, CI 1.18-1.81), biliary (OR 1.84, CI 1.34-2.52) or urinary source (OR 1.86, CI 1.43-2.43), admission period (OR) 1.28, CI 1.18-1.38, and community-acquired infection (OR 0.57, CI 0.39-0.82). The study showed an increase in MDR-GNB among SC patients with BSI. A quarter received IEAT, which was linked to increased mortality. Improving risk assessment for MDR infections and the judicious prescription of empiric antibiotics are crucial for better outcomes. IMPORTANCE: Multidrug-resistant (MDR) bacteria pose a global public health threat as they are more challenging to treat, and they are on the rise. Solid cancer patients are often immunocompromised due to their disease and cancer treatments, making them more susceptible to infections. Understanding the changes and trends in bloodstream infections in solid cancer patients is crucial, to help physicians make informed decisions about appropriate antibiotic therapies, manage infections in this vulnerable population, and prevent infection. Solid cancer patients often require intensive and prolonged treatments, including surgery, chemotherapy, and radiation therapy. Infections can complicate these treatments, leading to treatment delays, increased healthcare costs, and poorer patient outcomes. Investigating new strategies to combat MDR infections and researching novel antibiotics in these patients is of paramount importance to avoid these negative impacts.

RESUMO

Programmed cell death 2 (PDCD2) is related to cancer progression and chemotherapy sensitivity. The role of PDCD2 in solid cancers (excluding hematopoietic malignancies) and their diagnosis and prognosis remains unclear. The TCGA, CGGA, GEPIA, cBioPortal, and GTEx databases were analyzed for expression, prognostic value, and genetic modifications of PDCD2 in cancer patients. Functional enrichment analysis, CCK8, colony formation assay, transwell assay, and xenograft tumor model were undertaken to study the PDCD2's biological function in glioma (GBMLGG). The PDCD2 gene was associated with solid cancer progression. In the functional enrichment analysis results, PDCD2 was shown to participate in several important GBMLGG biological processes. GBMLGG cells may be inhibited in their proliferation, migration, invasion, and xenograft tumor growth by knocking down PDCD2. Our research can provide new insights into solid cancer prognostic biomarkers of PDCD2.

RESUMO

In recent years, next-generation sequencing (NGS)-based genetic testing has become crucial in cancer care. While its primary objective is to identify actionable genetic alterations to guide treatment decisions, its scope has broadened to encompass aiding in pathological diagnosis and exploring resistance mechanisms. With the ongoing expansion in NGS application and reliance, a compelling necessity arises for expert consensus on its application in solid cancers. To address this demand, the forthcoming recommendations not only provide pragmatic guidance for the clinical use of NGS but also systematically classify actionable genes based on specific cancer types. Additionally, these recommendations will incorporate expert perspectives on crucial biomarkers, ensuring informed decisions regarding circulating tumor DNA panel testing.

RESUMO

The gut microbiome significantly influences immune responses and the efficacy of immune checkpoint inhibitors. We conducted a clinical trial (NCT04264975) combining an anti-programmed death-1 (PD-1) inhibitor with fecal microbiota transplantation (FMT) from anti-PD-1 responder in 13 patients with anti-PD-1-refractory advanced solid cancers. FMT induced sustained microbiota changes and clinical benefits in 6 of 13 patients, with 1 partial response and 5 stable diseases, achieving an objective response rate of 7.7% and a disease control rate of 46.2%. The clinical response correlates with increased cytotoxic T cells and immune cytokines in blood and tumors. We isolated Prevotella merdae Immunoactis from a responder to FMT, which stimulates T cell activity and suppresses tumor growth in mice by enhancing cytotoxic T cell infiltration. Additionally, we found Lactobacillus salivarius and Bacteroides plebeius may inhibit anti-tumor immunity. Our findings suggest that FMT with beneficial microbiota can overcome resistance to anti-PD-1 inhibitors in advanced solid cancers, especially gastrointestinal cancers.

RESUMO

Numerous antibody biomarkers have been reported for cancer and atherosclerosis-related diseases. The major complications of atherosclerosis and diabetes mellitus (DM) are acute ischemic stroke (AIS), cardiovascular disease (CVD) and chronic kidney disease (CKD). Cancer development is accompanied by arterial disorders, such as angiogenesis and atherosclerosis, and DM is a risk factor for the development of certain types of cancer. Atherosclerosis-related diseases and cancers are therefore interrelated and could be detected using a common biomarker. In the present study, the initial screening using the protein array method identified KIAA0513 as an antigen recognized by serum IgG antibodies in patients with atherosclerosis. The amplified luminescent proximity homogeneous assay-linked immunosorbent assay revealed significantly higher serum antibody levels against recombinant KIAA0513 protein in patients with AIS, transient ischemic attack (TIA), DM, CVD, obstructive sleep apnea syndrome (OSAS), CKD and solid cancers, such as esophageal, gastric, colon, lung and breast cancers, compared with healthy donors. A receiver operating characteristic (ROC) analysis revealed that the highest areas under the ROC curves of anti-KIAA0513 antibodies were obtained for esophageal cancer, nephrosclerosis-type CKD and DM. Spearman's correlation analysis revealed that serum anti-KIAA0513 antibody levels were associated with maximum intima-media thickness and plaque score, which are indices of atherosclerosis and stenosis. Serum anti-KIAA0513 antibody markers appear to be useful for diagnosing AIS, TIA, DM, CVD, OSAS, CKD and solid cancers, and may reflect common arterial alterations leading to atherosclerotic and cancerous diseases.

RESUMO

PURPOSE: This systematic review and meta-analysis aimed to investigate the effectiveness of carbon ion radiotherapy (CIRT) compared to that of conventional radiotherapy in patients with various types of solid tumors. MATERIALS AND METHODS: We systematically searched eight electronic databases from inception until August 2022 in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The comparative effectiveness of the different treatment options was assessed by a random-effects meta-analysis. RESULTS: This review included 34 comparative studies and three treatment groups. Overall, the meta-analysis indicated comparable local control rates between the CIRT and control groups [pooled risk ratio (RR)=1.02, 95% confidence interval (CI) 0.90-1.15]. The local control rate in the CIRT group was higher than that in the photon therapy group, but slightly lower than that in the proton radiation therpy (PRT) group. Additionally, the CIRT group had significantly higher overall survival (OS) (RR=1.19, 95% CI=1.01-1.42) and progression-free survival (PFS) (RR=1.50, 95% CI=1.01-2.21) rates compared to the control group. In the subgroup analysis, survival rates were similar between the CIRT and PRT groups. CONCLUSION: CIRT was associated with improved toxicity, local tumor control, OS, and PFS compared to conventional treatments. Therefore, CIRT was found to be a safe and effective option for achieving local control in patients with solid tumors.

RESUMO

Introduction: Solid cancers Myeloid cells are prevalent in solid cancers, but they frequently exhibit an anti-inflammatory pro-tumor phenotype that contribute to the immunosuppressive tumor microenvironment (TME), which hinders the effectiveness of cancer immunotherapies. Myeloid cells' natural ability of tumor trafficking makes engineered myeloid cell therapy an intriguing approach to tackle the challenges posed by solid cancers, including tumor infiltration, tumor cell heterogenicity and the immunosuppressive TME. One such engineering approach is to target the checkpoint molecule PD-L1, which is often upregulated by solid cancers to evade immune responses. Method: Here we devised an adoptive cell therapy strategy based on myeloid cells expressing a Chimeric Antigen Receptor (CAR)-like immune receptor (CARIR). The extracellular domain of CARIR is derived from the natural inhibitory receptor PD-1, while the intracellular domain(s) are derived from CD40 and/or CD3ζ. To assess the efficacy of CARIR-engineered myeloid cells, we conducted proof-of-principle experiments using co-culture and flow cytometry-based phagocytosis assays in vitro. Additionally, we employed a fully immune-competent syngeneic tumor mouse model to evaluate the strategy's effectiveness in vivo. Result: Co-culturing CARIR-expressing human monocytic THP-1 cells with PD-L1 expressing target cells lead to upregulation of the costimulatory molecule CD86 along with expression of proinflammatory cytokines TNF-1α and IL-1ß. Moreover, CARIR expression significantly enhanced phagocytosis of multiple PD-L1 expressing cancer cell lines in vitro. Similar outcomes were observed with CARIR-expressing human primary macrophages. In experiments conducted in syngeneic BALB/c mice bearing 4T1 mammary tumors, infusing murine myeloid cells that express a murine version of CARIR significantly slowed tumor growth and prolonged survival. Conclusion: Taken together, these results demonstrate that adoptive transfer of PD-1 CARIR-engineered myeloid cells represents a promising strategy for treating PD-L1 positive solid cancers.

RESUMO

Background: Blocking the CD47 "don't eat me"-signal on tumor cells with monoclonal antibodies or fusion proteins has shown limited clinical activity in hematologic malignancies and solid tumors thus far. Main side effects are associated with non-tumor targeted binding to CD47 particularly on blood cells. Methods: We present here the generation and preclinical development of NILK-2401, a CEACAM5×CD47 bispecific antibody (BsAb) composed of a common heavy chain and two different light chains, one kappa and one lambda, determining specificity (so-called κλ body format). Results: NILK-2401 is a fully human BsAb binding the CEACAM5 N-terminal domain on tumor cells by its lambda light chain arm with an affinity of ≈4 nM and CD47 with its kappa chain arm with an intendedly low affinity of ≈500 nM to enabling tumor-specific blockade of the CD47-SIRPα interaction. For increased activity, NILK-2401 features a functional IgG1 Fc-part. NILK-2401 eliminates CEACAM5-positive tumor cell lines (3/3 colorectal, 2/2 gastric, 2/2 lung) with EC50 for antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity ranging from 0.38 to 25.84 nM and 0.04 to 0.25 nM, respectively. NILK-2401 binds neither CD47-positive/CEACAM5-negative cell lines nor primary epithelial cells. No erythrophagocytosis or platelet activation is observed. Quantification of the pre-existing NILK-2401-reactive T-cell repertoire in the blood of 14 healthy donors with diverse HLA molecules shows a low immunogenic potential. In vivo, NILK-2401 significantly delayed tumor growth in a NOD-SCID colon cancer model and a syngeneic mouse model using human CD47/human SIRPα transgenic mice and prolonged survival. In cynomolgus monkeys, single doses of 0.5 and 20 mg/kg were well tolerated; PK linked to anti-CD47 and Fc-binding seemed to be more than dose-proportional for Cmax and AUC0-inf. Data were validated in human FcRn TG32 mice. Combination of a CEACAM5-targeting T-cell engager (NILK-2301) with NILK-2401 can either boost NILK-2301 activity (Emax) up to 2.5-fold or allows reaching equal NILK-2301 activity at >600-fold (LS174T) to >3,000-fold (MKN-45) lower doses. Conclusion: NILK-2401 combines promising preclinical activity with limited potential side effects due to the tumor-targeted blockade of CD47 and low immunogenicity and is planned to enter clinical testing.

RESUMO

Solid cancer patients, compared to their healthy counterparts, are at a greater risk of contracting and suffering from severe complications and poorer prognosis after COVID-19 infections. They also have different immune responses after doses of COVID-19 vaccination, but limited evidence is available to reveal the effectiveness and help to guide immunization programs for this subpopulation; MEDLINE, Embase, Web of Science, Cochrane Library databases, and clinicaltrials.gov were used to search literature. The pooled seroconversion rate was calculated using a random-effects model and reported with a 95% confidence interval (CI); The review includes 66 studies containing serological responses after COVID-19 vaccination in 13,050 solid cancer patients and 8550 healthy controls. The pooled seropositive rates after the first dose in patients with solid cancer and healthy controls are 55.2% (95% CI 45.9%-64.5% N = 18) and 90.2% (95% CI 80.9%-96.6% N = 13), respectively. The seropositive rates after the second dose in patients with solid cancer and healthy controls are 87.6% (95% CI 84.1%-90.7% N = 50) and 98.9% (95% CI 97.6%-99.7% N = 35), respectively. The seropositive rates after the third dose in patients with solid cancer and healthy controls are 91.4% (95% CI 85.4%-95.9% N = 21) and 99.8% (95% CI 98.1%-100.0% N = 4), respectively. Subgroup analysis finds that study sample size, timing of antibody testing, and vaccine type have influence on the results; Seroconversion rates after COVID-19 vaccination are significantly lower in patients with solid malignancies, especially after the first dose, then shrinking gradually after the following two vaccinations, indicating that subsequent doses or a booster dose should be considered for the effectiveness of this subpopulation.

RESUMO

Considerable advances in the diagnosis and treatment of cancer have made a huge impact on morbidity and mortality from neoplastic diseases. However, cancer remains the leading cause of death across the world. This is a retrospective study carried out at a tertiary cancer care centre (Kidwai Memorial Institute of Oncology, Bangalore) in South India. Case records of all cancer patients who died while receiving inpatient treatment between January 2022 and December 2022 under the Department of Medical Oncology were reviewed and studied. There was a total of 240 deaths. Out of these, the majority of deaths 147 (61.25%) were patients with haematological malignancies while the remaining 93 (38.75%) were patients with solid tumours. In patients with solid tumours, the majority 49 (52.7%) were in the age group of 40 to 60 years while only 18 (19.35%) patients were less than 40 years. The majority of patients were male sex i.e. 55(59.1%) and undergoing treatment with palliative intent 81 (87%). The most common organ was the lung in 21 patients (22.6%) followed by the breast while the most common system involved was the gastrointestinal tract in 28 (30.1%) patients. The most frequent cause of death was progressive disease in 72 (77.4%) while sepsis (11 patients; 11.8%) was the second most frequent cause of death in solid tumours. In haematological malignancies, also a significant number of 57 (38.8%) patients were in the age group of 40 to 60 years. Fifty-two (35.3%) patients were in the age group of 22 to 40 years. The majority were male sex (79 patients; 53.7%). About the phase of treatment, the majority of deaths 45 (30.6%) were during induction and under evaluation. Those with relapse/refractory disease were 38 (25.9%). A substantial number of patients had acute myeloid leukaemia 47 (32%) and five (3.4%) deaths were acute promyelocytic leukaemia patients. Twenty-three patients (15.6%) had acute lymphoblastic leukaemia. The most common cause of death was sepsis in 76 patients (51.7%) while intracranial bleeding was in 34 patients (23.1%). In some patients, there were multiple causes leading to death. Mortality audits are important to evaluate the services being provided at any centre. One can appreciate the lacunae in handling a particular disease or flaws in a treatment protocol or the staff delivering the treatment. Sepsis is the leading cause of death in patients with haematological malignancy; even in solid malignancy sepsis accounts for a substantial proportion of deaths and should be handled aggressively to save lives.

RESUMO

The objective of this single-center retrospective study was to describe the clinical characteristics of adult patients with solid tumors enrolled in cancer clinical trials over a 10-year period (2010-2019) and to assess drug cost avoidance (DCA) associated with sponsors' contributions. The sponsors' contribution to pharmaceutical expenditure was calculated according to the actual price (for each year) of pharmaceutical specialties that the Vall d'Hebron University Hospital (HUVH) would have had to bear in the absence of sponsorship. A total of 2930 clinical trials were conducted with 10,488 participants. There were 140 trials in 2010 and 459 in 2019 (228% increase). Clinical trials of high complexity phase I and basket trials accounted for 34.3% of all trials. There has been a large variation in the pattern of clinical research over the study period, whereas, in 2010, targeted therapy accounted for 79.4% of expenditure and cytotoxic drugs for 20.6%; in 2019, immunotherapy accounted for 68.4%, targeted therapy for 24.4%, and cytotoxic drugs for only 7.1%. A total of four hundred twenty-one different antineoplastic agents were used, the variability of which increased from forty-seven agents in 2010, with only seven of them accounting for 92.8% of the overall pharmaceutical expenditure) to three hundred seventeen different antineoplastic agents in 2019, with thirty-three of them accounting for 90.6% of the overall expenditure. The overall expenditure on antineoplastic drugs in clinical care patients not included in clinical trials was EUR 120,396,096. The total cost of antineoplastic drugs supplied by sponsors in a clinical trial setting was EUR 107,306,084, with a potential DCA of EUR 92,662,609. Overall, clinical trials provide not only the best context for the progress of clinical research and healthcare but also create opportunities for reducing cancer care costs.

RESUMO

BACKGROUND: Nutritional impact symptoms (NISs) are proposed to be a key indicator of decreased dietary intake in patients with solid cancer. Cancer patients frequently experience NIS from the disease itself and from disease treatment side effects that impact oral and gastrointestinal health. Thus, this study aimed to investigate the association between NIS and dietary intake among cancer patients in the Nablus district, one of the largest districts in Palestine. This study also sought to identify the types of treatment and other factors related to dietary intake for solid cancer patients. METHODS: A cross-sectional study was conducted between October 15, 2021, and October 15, 2022. The convenience sampling technique was used to recruit participants from two primary hospital campuses for cancer treatment in the entire region of Nablus Governorate in northern Palestine. To assess the patients, structured questionnaires completed by interviewers during face-to-face interviews with patients were used. The NIS was assessed using a checklist developed based on a literature review and clinical experience. Univariate and multivariate analyses were used to evaluate the correlations between sociodemographic variables and clinical variables and between the NIS and dietary intake. Multiple binary logistic regression analyses were also performed to determine the most influential variables, sociodemographic, clinical, and NIS, on dietary intake. RESULTS: Data were collected from 290 patients with solid malignancies. The mean age of the participants was 55.04 ± 12.76 years. Multiple binary logistic regressions revealed that dry mouth (odds ratio (OR) = 3.742; 95% confidence interval (CI) = 1.800-7.780; p < 0.001), constipation (OR = 2.707; 95% CI = 1.113-6.581; p = 0.028), taste alteration (OR = 3.620; 95% CI = 1.752-7.481; p = 0.001), and feeling fullness (OR = 8.879; 95% CI = 2.982-26.441; p < 0.001) were significantly related to decreased dietary intake. Biological and hormonal treatments had an inverse association with dietary intake (OR = 0.372; 95% CI = 0.177-0.782; p = 0.009 and OR = 0.383; 95% CI = 0.168-0.874; p = 0.023, respectively). CONCLUSIONS: This study revealed that many solid cancer patients have reduced food intake due to NIS, such as dry mouth and taste changes. These patients may be at risk of malnutrition. Healthcare professionals should consider these NISs to improve dietary plans and decide whether extra feeding support is needed. The results obtained indicate the need for further research focused on removing limitations in food consumption as an effect of treatment and appropriate nutritional strategies to prevent patient malnutrition.

RESUMO

Immune checkpoint inhibitors (ICI) and tyrosine kinase inhibitors (TKI) have gained therapeutical significance in cancer therapy over the last years. Due to the high efficacy of each substance group, additive or complementary effects are considered, and combinations are the subject of multiple prospective trials in different tumor entities. The majority of available data results from clinical phase I and II trials. Although regarded as well-tolerated therapies ICI-TKI combinations have higher toxicities compared to monotherapies of one of the substance classes and some combinations were shown to be excessively toxic leading to discontinuation of trials. So far, ICI-TKI combinations with nivolumab + cabozantinib, pembrolizumab + axitinib, avelumab + axitinib, pembrolizumab + lenvatinib have been approved in advanced renal cell (RCC), with pembrolizumab + lenvatinib in endometrial carcinoma and with camrelizumab + rivoceranib in hepatocellular carcinoma (HCC). Several ICI-TKI combinations are currently investigated in phase I to III trials in various other cancer entities. Further, the optimal sequence of ICI-TKI combinations is an important subject of investigation, as cross-resistances between the substance classes were observed. This review reports on clinical trials with ICI-TKI combinations in different cancer entities, their efficacy and toxicity.

RESUMO

PIM3 (provirus-integrating Moloney site 3) is a serine/threonine kinase and belongs to the PIM family (PIM1, PIM2, and PIM3). PIM3 is a proto-oncogene that is frequently overexpressed in cancers originating from endoderm-derived tissues, such as the liver, pancreas, colon, stomach, prostate, and breast cancer. PIM3 plays a critical role in activating multiple oncogenic signaling pathways promoting cancer cell proliferation, survival, invasion, tumor growth, metastasis, and progression, as well as chemo- and radiation therapy resistance and immunosuppressive microenvironment. Genetic inhibition of PIM3 expression suppresses in vitro cell proliferation and in vivo tumor growth and metastasis in mice with solid cancers, indicating that PIM3 is a potential therapeutic target. Although several pan-PIM inhibitors entered phase I clinical trials in hematological cancers, there are currently no FDA-approved inhibitors for the treatment of patients. This review provides an overview of recent developments and insights into the role of PIM3 in various cancers and its potential as a novel molecular target for cancer therapy. We also discuss the current status of PIM-targeted therapies in clinical trials.
