RESUMO
BACKGROUND: The therapeutic potential of immune checkpoint blockade (ICB) extends across various cancers; however, its effectiveness in treating hepatocellular carcinoma (HCC) is frequently curtailed by both inherent and developed resistance. OBJECTIVE: This research explored the effectiveness of integrating anlotinib (a broad-spectrum tyrosine kinase inhibitor) with programmed death-1 (PD-1) blockade and offers mechanistic insights into more effective strategies for treating HCC. METHODS: Using patient-derived organotypic tissue spheroids and orthotopic HCC mouse models, we assessed the effectiveness of anlotinib combined with PD-1 blockade. The impact on the tumour immune microenvironment and underlying mechanisms were assessed using time-of-flight mass cytometry, RNA sequencing, and proteomics across cell lines, mouse models, and HCC patient samples. RESULTS: The combination of anlotinib with an anti-PD-1 antibody enhanced the immune response against HCC in preclinical models. Anlotinib remarkably suppressed the expression of transferrin receptor (TFRC) via the VEGFR2/AKT/HIF-1α signaling axis. CD8+ T-cell infiltration into the tumour microenvironment correlated with low expression of TFRC. Anlotinib additionally increased the levels of the chemokine CXCL14, crucial for attracting CD8+ T cells. CXCL14 emerged as a downstream effector of TFRC, exhibiting elevated expression following the silencing of TFRC. Importantly, low TFRC expression was also associated with a better prognosis, enhanced sensitivity to combination therapy, and a favourable response to anti-PD-1 therapy in patients with HCC. CONCLUSIONS: Our findings highlight anlotinib's potential to augment the efficacy of anti-PD-1 immunotherapy in HCC by targeting TFRC and enhancing CXCL14-mediated CD8+ T-cell infiltration. This study contributes to developing novel therapeutic strategies for HCC, emphasizing the role of precision medicine in oncology. HIGHLIGHTS: Synergistic effects of anlotinib and anti-PD-1 immunotherapy demonstrated in HCC preclinical models. Anlotinib inhibits TFRC expression via the VEGFR2/AKT/HIF-1α pathway. CXCL14 upregulation via TFRC suppression boosts CD8+ T-cell recruitment. TFRC emerges as a potential biomarker for evaluating prognosis and predicting response to anti-PD-1-based therapies in advanced HCC patients.

OBJECTIVES: There is limited data on the incidence, prevalence, and treatments for myelofibrosis (MF) in Germany. This retrospective study examined claims data from 3.3 million insured individuals, spanning from 2010 to 2021. METHODS: Four sensitivity scenarios were explored to identify cases of MF. Point prevalence and cumulative incidence of MF were determined as of December 31, 2021, and within 2021, respectively. A cross-sectional analysis used the main scenario definition of MF to identify cases and evaluate the period prevalence of patients receiving treatment for symptoms and/or splenomegaly, including first-line (1L) Janus kinase inhibitor (JAKi), second-line, or further (2L+) MF-related treatment therapies during 2021. The prevalence of anemia treatment was also reported. RESULTS: The estimated standardized point prevalence of MF on December 31, 2021, was 9.9-12.4 cases per 100 000 persons, and cumulative incidence in 2021 was 1.2-1.8 cases per 100 000 persons. Standardized period prevalence in 2021 for MF patients receiving 1L JAKi and/or 2L+ MF-related treatment was 4.0 cases per 100 000. Among these patients, 47.1%-53.7% required treatment for anemia, resulting in a period prevalence of 1.9-2.2 cases per 100 000 individuals. CONCLUSION: The data reveal gaps in MF treatments and the need to improve patient quality of life.
RESUMO
Tumor progression depends on angiogenesis, which is stimulated by growth factors like VEGF, targeting VEGFR kinase with small molecules is an effective anti-angiogenic therapeutic approach. Sunitinib was rationally modified to spirocyclopropyloxindoline carboxamides and their in vitro cytotoxic profiling were evaluated. The molecular modelling studies enabled the screening of designed analogues and identified possible interactions within the type III allosteric inhibitor binding site of VEGFR-2. The biological screening of compounds 15a-y, revealed the ability of compound 15w to inhibit the cell growth in MCF-7 cells with IC50 value of 3.87 ± 0.19 µM and alongside inhibition of VEGFR-2 kinase at a IC50 concentration of 4.34 ± 0.13 µM was observed. VEGFR-2 inhibition was validated through HUVEC tube formation inhibition assay. 15w also inhibited cell migration in wound healing assay. The qualitative assessment of apoptosis induction by 15w in MCF-7 cells was evaluated through AO/EB and DAPI staining studies, whereas apoptotic quantification and cell cycle analysis were performed through FACS analysis. The current study strives to sequentially optimize the structural attributes of 3-alkenyl oxindole core to surpass the existing challenges of well-known VEGFR-2 inhibitors and compound 15w was identified to be a prominent lead towards the development of clinical drug candidates.
RESUMO
BACKGROUND: Platinum-resistant or refractory ovarian cancer is a highly lethal gynecologic disease with limited treatment options. Chiauranib is a novel small-molecule selective inhibitor, which could effectively target multiple pathways including Aurora B and CSF-1R to inhibit cell cycle process and improve anti-tumor immune function, as long as VEGF pathway for tumor extinction. METHODS: A phase II study was sequentially conducted after a phase Ib monotherapy study to evaluate the efficacy of chiauranib combined with chemotherapy. Chinese patients with recurrent ovarian cancer were enrolled. Eligible patients received chiauranib combined with a maximum of six cycles of chemotherapy: etoposide (CE group) or weekly-paclitaxel (CP group). Patients, who exhibited a complete or partial response, or stable disease following combo treatment, progressed to maintenance phase to receive chiauranib monotherapy. Primary endpoint was progression-free survival (PFS) according to RECIST v1.1. RESULTS: From November 2017 to March 2019, 25 patients were enrolled in a phase 1b study and a median PFS of 3.7 months (95% CI 1.8-NE) was achieved by chiauranib monotherapy. From July 2019 to December 2020, a total of 47 patients were enrolled in the phase II study. One CP patient did not receive the study drugs, and three patients withdrew before the first tumor assessment. Thus, 43 patients (CE group: 22 patients; CP group: 21 patients) were included in the evaluation. The median PFS was 5·4 months (95% CI 2·8-5·6) and 5·6 months (95% CI 3·4-7·0), respectively. CONCLUSIONS: This was the first study to evaluate chiauranib, a novel multi-targeted kinase inhibitor in patients with ovarian cancer. The administration of chiauranib along with etoposide or weekly-paclitaxel significantly enhanced the efficacy with manageable adverse events. This warrants further clinical studies on this novel treatment. A phase III study is promising and ongoing. TRIAL REGISTRATION: ClinicaTrials.gov identifier: NCT03901118 (phase II) and NCT03166891 (phase Ib).

Novel therapeutic agents in clinical trials offer a paradigm shift in the approach to battling this prevalent and destructive disease, and the area of cancer therapy is on the precipice of a trans formative revolution. Despite the importance of tried-and-true cancer treatments like surgery, radiation, and chemotherapy, the disease continues to evolve and adapt, making new, more potent methods necessary. The field of cancer therapy is currently witnessing the emergence of a wide range of innovative approaches. Immunotherapy, including checkpoint inhibitors, CAR-T cell treatment, and cancer vaccines, utilizes the host's immune system to selectively target and eradicate malignant cells while minimizing harm to normal tissue. The development of targeted medicines like kinase inhibitors and monoclonal antibodies has allowed for more targeted and less harmful approaches to treating cancer. With the help of genomics and molecular profiling, "precision medicine" customizes therapies to each patient's unique genetic makeup to maximize therapeutic efficacy while minimizing unwanted side effects. Epigenetic therapies, metabolic interventions, radio-pharmaceuticals, and an increasing emphasis on combination therapy with synergistic effects further broaden the therapeutic landscape. Multiple-stage clinical trials are essential for determining the safety and efficacy of these novel drugs, allowing patients to gain access to novel treatments while also furthering scientific understanding. The future of cancer therapy is rife with promise, as the integration of artificial intelligence and big data has the potential to revolutionize early detection and prevention. Collaboration among researchers, and healthcare providers, and the active involvement of patients remain the bedrock of the ongoing battle against cancer. In conclusion, the dynamic and evolving landscape of cancer therapy provides hope for improved treatment outcomes, emphasizing a patient-centered, data-driven, and ethically grounded approach as we collectively strive towards a cancer-free world.
RESUMO
Background: Lenvatinib is the first-line treatment option for patients with advanced hepatocellular carcinoma (HCC); however, the impact of lenvatinib resistance on patient prognosis is unknown. Methods: We recruited all patients with advanced HCC who received first-line lenvatinib treatment between February 2019 and February 2023 at two medical centers in China, according to the selection criteria. The patients were divided into primary and secondary resistance groups based on tumor progression within 3 months. The Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS). Logistic regression and Cox proportional hazards models were used to explore factors influencing drug resistance and prognosis. The study end points were drug resistance, PFS, and OS. Results: A total of 531 patients met the study criteria, with 169 (31.8%) and 362 (68.2%) patients in the primary and secondary groups, respectively. An alpha-fetoprotein (AFP) concentration > 400 ng/mL was an independent risk factor for primary drug resistance. Patients in the primary group had a significantly shorter median OS (11.0 vs 31.0 months, P<0.001) than those in the secondary group. The 1-, 2- and 3-year cumulative survival rates in the primary group were 46.3%, 22.2%, and 10.1%, while those in the secondary group were 82.3%, 59.1% and 44.9%, respectively. Compared to tyrosine kinase inhibitor (TKI) monotherapy, longer median PFS (4.0 vs 7.0 months, P=0.008) and OS (11.0 vs 23.0 months, P=0.024) were achieved with the combination of a TKI plus a PD-1 inhibitor as a second-line therapy after lenvatinib resistance. Conclusion: There is a high rate of primary resistance to lenvatinib in patients with HCC and the prognosis for those with primary resistance is poor. TKI combined with PD-1 inhibitors should be preferentially recommended for lenvatinib-resistant patients.
RESUMO
Fibroblast Growth Factor Receptors (FGFRs) are emerging as key factors involved in tumorigenesis, tumor microenvironment remodeling and acquired resistance to targeted therapies. Pemigatinib is a Tyrosine-Kinase Inhibitor that selectively targets aberrant FGFR1, FGFR2 and FGFR3. Pemigatinib is now approved for advanced-stage cholangiocarcinoma (CCA) but data suggests that other tumor histotypes exhibit FGFR alterations, thus hypothesizing its potential efficacy in other cancer settings. The present systematic review, based on PRISMA guidelines, aims to synthetize and critically interpret the results of all available preclinical and clinical evidence regarding Pemigatinib use in cancer. In April 2024, an extensive search was performed in PubMed, MEDLINE, and Scopus databases using the keyword "Pemigatinib". Twenty-seven studies finally met all inclusion criteria. The promising results emerging from Pemigatinib preclinical and clinical studies pave the way for Pemigatinib extension to multiple solid cancer settings.
RESUMO
Cytochrome P450 (CYP) 2J2 is responsible for the epoxidation of arachidonic acid, producing epoxyeicosatrienoic acids (EETs) that are known to enhance tumorigenesis. CYP2J2 is prominently expressed in the heart and also found in the lungs. Furthermore, the expression level of CYP2J2 in tumour tissues is higher than that in adjacent normal tissues. Non-small cell lung carcinoma is a common cancer, and tyrosine kinase inhibitors (TKIs) are powerful tools for its treatment. This study aimed to elucidate the inhibitory effects of 17 TKIs on CYP2J2 activity using LC-MS/MS.Seventeen TKIs exhibited different inhibitory effects on CYP2J2-catalysed astemizole O-demethylation in recombinant CYP2J2. Pralsetinib and selpercatinib showed strong competitive inhibition, with inhibition constant values of 0.48 and 1.1 µM, respectively. They also inhibited other CYP2J2 activities, including arachidonic acid epoxidation, hydroxyebastine carboxylation, and rivaroxaban hydroxylation.In conclusion, we showed that pralsetinib and selpercatinib strongly inhibit CYP2J2 activity. Inhibition of 14,15-EET production by these TKIs may be a novel mechanism for suppressing tumour growth and proliferation. Additionally, when these TKIs are co-administered with a CYP2J2 substrate, we may consider the possibility of drug-drug interactions via CYP2J2 inhibition.
RESUMO
The management of chronic myeloid leukemia in the chronic phase (CML-CP) has witnessed significant advancements since the identification of a common chromosomal translocation anomaly involving chromosomes 9 and 22, which results in the formation of the Philadelphia chromosome driven by the BCR-ABL1 fusion protein. This discovery paved the way for the development of tyrosine kinase inhibitors (TKIs) that target the adenosine triphosphate (ATP) binding site of ABL1 through the BCR-ABL-1 fusion protein. Following the approval of Imatinib by the Food and Drug Administration (FDA) as the first TKI for CML treatment in 2001, the median overall survival (OS) for chronic phase CML (CML-CP) has significantly improved, approaching that of the general population. However, achieving this milestone crucially depends on reaching certain treatment response milestones. Since the introduction of imatinib, five additional TKIs have been approved for CML-CP treatment. Despite the availability of these treatments, many patients may experience treatment failure and require multiple lines of therapy due to factors such as the emergence of resistance, such as mutations in the ATP binding site of ABL, or intolerance to therapy. This review will primarily focus on exploring treatment options for patients who fail second-generation TKI therapy due to true resistance.
RESUMO
Objective: The purpose of the study was to identify the best sequence of therapy beginning with a tyrosine kinase inhibitor (TKI) as the first-line therapy for patients with metastatic renal cell carcinoma (mRCC) in terms of overall survival (OS), progression-free survival (PFS), and rates of discontinuation and adverse effects during the treatment period. Methods: This is a retrospective, nationwide multicenter study of patients with mRCC after diagnosis at 10 different tertiary medical centers in Korea from January 1992 to December 2017. We focused on patients at either "favorable" or "intermediate" risk according to the International mRCC Database Consortium criteria, and they were followed up (median 335 days). Finally, a total of 1409 patients were selected as the study population. We generated a Cox proportional hazard model adjusted for covariates, and the different therapy schemes were statistically tested in terms of OS as well as PFS. In addition, frequencies of discontinuation and adverse events were compared among the therapy schemes. Results: Of the primary patterns of treatment sequences (24 sequences), "sunitinib-pazopanib" and "sunitinib-everolimus-immunotherapy" showed the most beneficial results in both OS and PFS with significantly lower hazards than "sunitinib", which is the most commonly treated agent in Korea. Considering that the "TKI-TKI" structure showed relatively higher discontinuation rates with higher adverse effects, the overall beneficial sequence would be "sunitinib-everolimus-immunotherapy". Conclusion: Among several sequential therapy starting with TKIs, "sunitinib-everolimus- immunotherapy" was found to be the best scheme for mRCC patients with "favorable" or "intermediate" risks.
RESUMO
Although bosutinib is generally safe and effective, drug-related toxicities (DRTs) such as diarrhea or increased transaminase levels often lead to treatment discontinuation. To clarify whether a lower initial dose of bosutinib (i.e., starting at 200 mg) would reduce rates of discontinuation due to DRTs, we conducted a phase 2 study of BOsutinib Gradual Increase (BOGI trial, UMIN 000032282) as a second/third-line treatment for chronic myeloid leukemia (CML). Between February 4, 2019 and May 24, 2022, 35 patients were enrolled. The rate of bosutinib discontinuation at 12 months was 25.7% vs. 35.9% in a historical control study (Japanese phase 1/2 study) (p = 0.102). The rate of bosutinib discontinuation due to DRTs was significantly lower, at 11.4% vs. 28.2% (p = 0.015). The incidence of grade 3/4 transaminase elevation was 20% vs. 29% (p = 0.427), while the incidence of diarrhea was 3% vs. 25% (p = 0.009). The median dose intensity of bosutinib was higher (391.7 mg/day vs. 353.9 mg/day). Pharmacokinetic analysis of bosutinib showed that patients who achieved a major molecular response tended to have high trough concentrations. Thus, a low initial dose of bosutinib followed by dose escalation reduced discontinuation due to severe DRTs while maintaining high dose intensity and efficacy.
RESUMO
Objectives: This study aimed to evaluate the incidence of Herpes Zoster (HZ) in patients with rheumatoid arthritis (RA) treated with Janus kinase inhibitors (JAKi), and to predict potential risk factors for HZ development. Methods: We retrospectively analysed medical records from RA patients at our rheumatology unit who met the 2010 ACR/EULAR criteria for RA and were receiving JAKi. The incidence and course of HZ were assessed through chart review and supplementary phone interviews. Results: A total of 198 JAKi-treated patients were monitored for an average of 18.5 months. Nine subjects experienced HZ, resulting in an incidence of 2.95 per 100 patient-years. No demographic or treatment-related differences were found among patients who developed HZ and those who did not. Disease duration (OR: 1.06, 95% CI: 1.01-1.12), time on JAKi treatment (OR: 1.04, 95% CI: 1.009-1.073), higher disease activity at JAKi initiation (OR: 4.16, 95% CI: 1.07-16.17), and at 3-month follow-up (OR: 6.0, 95% CI: 1.35-26.60) were identified as predictors of HZ occurrence. Thirty-six patients received vaccination against HZ, and none reported adverse reactions or flare-ups during a mean follow-up of 9.6 months. Conclusions: The incidence of HZ aligns with published data, suggesting that disease and treatment duration, as well as disease activity, are significant predictors of HZ in RA patients on JAKi therapy. Vaccination against HZ proved to be safe and effective, underscoring its potential protective value in this patient population.
RESUMO
Background: It is difficult for chronic myeloid leukemia (CML) patients with BCR::ABL1 independent drug resistance to achieve optimal efficacy. The aim of this study is to investigate the BCR::ABL1 kinase independent mechanism of tyrosine kinase inhibitor (TKI) resistance in CML patients to develop targeted therapeutic strategy. Methods: Herein, we analyzed the long non-coding RNA (lncRNA) and messenger RNA (mRNA) expression profiles of patients who achieved sustained deep molecular response (DMR) after TKI treatment and patients with non-DMR using RNA-seqencing. Furthermore, the differentially expressed lncRNAs and mRNAs were identified. The expression of chosen lncRNA was validated in an expanded cohort, and bioinformatics analysis was performed to analyze the function of selected mRNA. Results: LncRNA data analysis indicated the diversity lncRNA profiles among healthy individuals, CML patients with non-DMR, and CML patients with DMR. Differential expression analysis and Veen plot of up-regulated lncRNAs in patients with non-DMR (compared with healthy individuals) and down-regulated lncRNAs in patients with DMR (compared to patients with non-DMR) revealed that lncRNA CBR3-AS1 overexpression might be related to BCR::ABL1 independent TKI resistance of CML patients. The expression of CBR3-AS1 was then verified in an expanded cohort, suggesting that, compared with control group, there was no statistical difference of CBR3-AS1 expression in DMR group, whereas, CBR3-AS1 was up-regulated in non-DMR group. Moreover, the mRNA data analysis of RNA-sequencing was performed. We considered genes that up-regulated in non-DMR group (compared with control group), down-regulated in DMR group (compared with non-DMR group), showed no statistical difference between control and DMR group as the potential genes that associated with TKI resistance of CML patients. A total of 55 corresponding mRNAs were obtained including KCNA6, a target gene of CBR3-AS1. Further bioinformatics analysis showed that the major interacted genes of KCNA6 were enriched in several resistance-associated pathways including interleukin -17 signaling pathway and cyclic adenosine monophosphate signaling pathway. Conclusions: In conclusion, this work indicates that CBR3-AS1 might be involved in BCR::ABL1 independent TKI resistance of CML patients through targeting KCNA6, providing a novel target for intervention treatment of CML patients with BCR::ABL1 independent TKI resistance.
RESUMO
BACKGROUND: PDGFRB fusions in acute lymphoblastic leukemia (ALL) is rare. The authors identified 28 pediatric PDGFRB-positive ALL. They analyzed the features, outcomes, and prognostic factors of this disease. METHODS: This multicenter, retrospective study included 6457 pediatric patients with newly diagnosed PDGFRB fusion ALL according to the CCCG-ALL-2015 and CCCG-ALL-2020 protocols from April 2015 to April 2022 in 20 hospitals in China. Of these patients, 3451 were screened for PDGFRB fusions. RESULTS: Pediatric PDGFRB-positive ALL accounted for only 0.8% of the 3451 cases tested for PDGFRB. These patients included 21 males and seven females and 24 B-ALL and 4 T-ALL; the median age was 10 years; and the median leukocyte count was 29.8 × 109/L at baseline. Only one patient had eosinophilia. Three patients had an IKZF1 deletion, three had chromosome 5q31-33 abnormalities, and one suffered from a complex karyotype. The 3-year event-free survival (EFS), overall survival (OS), and cumulative incidence of relapse (CIR) were 33.1%, 65.5%, and 32.1%, respectively, with a median follow-up of 25.5 months. Twenty patients were treated with chemotherapy plus tyrosine-kinase inhibitors (TKIs) and eight were treated without TKI. Complete remission (CR) rates of them were 90.0% and 63.6%, respectively, but no differences in EFS, OS, or CIR. Univariate analyses showed patients with IKZF1 deletion or measurable residual disease (MRD) ≥0.01% after induction had inferior outcomes (p < .05). CONCLUSIONS: Pediatric PDGFRB-positive ALL has a poor outcome associated with high-risk features. Chemotherapy plus TKIs can improve the CR rate, providing an opportunity for lower MRD levels and transplantation. MRD ≥0.01% was a powerful adverse prognostic factor, and stratified treatment based on MRD may improve survival for these patients. PLAIN LANGUAGE SUMMARY: Pediatric acute lymphoblastic leukemia patients with PDGFRB fusions are associated with high-risk clinical features such as older age, high white blood cell count at diagnosis, high measurable residual disease after induction therapy, and increased risk of leukemia relapse. Chemotherapy plus tyrosine-kinase inhibitors can improve the complete remission rate and provide an opportunity for lower measurable residual disease (MRD) levels and transplantation for pediatric PDGFRB-positive acute lymphoblastic leukemia (ALL) patients. The MRD level was also a powerful prognostic factor for pediatric PDGFRB-positive ALL patients.
RESUMO
INTRODUCTION: Adult dermatomyositis (DM) and juvenile dermatomyositis (JDM) are rare autoimmune diseases with characteristic skin rashes, weakness, and other systemic features. Upregulated interferon signaling has been consistently described in both adult and juvenile DM which makes janus kinase inhibitors (jakinibs) an attractive therapeutic agent that has a targeted mechanism of action. AREAS COVERED: Herein is a review of the growing literature of jakinib use in adult and juvenile DM, including reports on specific disease features and safety of jakinibs in this population and a comparison between adult and juvenile DM. We performed a literature review using PubMed including all English-language publications before 1 February 2024 and abstracts from key recent rheumatology conferences. EXPERT OPINION: Jakinibs are an exciting and promising treatment in both adult and juvenile DM. Current Phase 2 and 3 randomized placebo-controlled trials of jakinibs in both adult and JDM will provide significant insights into the efficacy of this class of medication as a potentially more mechanistically targeted treatment of both skin and muscle disease. In fact, these results will likely inform the treatment paradigm of dermatomyositis in that it may even be considered as first or second line. The next five years in the therapeutic landscape of both juvenile and adult DM is an exciting time for both patients and medical providers.
RESUMO
INTRODUCTION: Zanzalintinib (XL092) is a next-generation anti-VEGFR-related multi-targeted TKI that exhibits immunomodulatory effects. AREAS COVERED: This review explores preclinical and clinical data, along with the future directions associated with zanzalintinib and its combination with immune checkpoint inhibitors (ICIs). EXPERT OPINION: In addition to its anti-VEGFR activity, zanzalintinib demonstrates potential synergistic effects with ICIs through its immunomodulatory impact, attributed to its inhibition of MET and TAM kinases. Recent preclinical studies provide compelling evidence supporting this synergistic potential. Furthermore, a recent phase 1 dose escalation study confirmed the tolerability of the zanzalintinib and anti-PDL1 combination without major safety concerns.Multiple ongoing clinical trials are investigating the combination of zanzalintinib and ICIs across various solid tumor types, including phase 3 studies for renal cell carcinoma, colorectal, and head and neck cancer. These trials aim to elucidate the therapeutic role of this new-generation TKI and ICI combination.However, the identification of reliable predictive biomarkers for the zanzalintinib and ICI combination presents significant challenges. Given the intricate nature of their mechanistic rationale and the difficulties in identifying reliable biomarkers for combined anti-angiogenesis and ICI therapies, addressing this challenge remains a priority for ongoing and future research.
RESUMO
INTRODUCTION: Real-world data are limited on treatment sequencing and outcomes after first-line (1L) immune checkpoint inhibitor (CPI)-based combination treatment of advanced renal cell carcinoma (aRCC). PATIENTS AND METHODS: In this real-world, UK-based, retrospective study (CARINA; NCT04957160), data were obtained from hospital and electronic prescribing records. Patients were aged ≥ 18 years at aRCC diagnosis and had received 1L CPI-CPI or tyrosine kinase inhibitor (TKI)-CPI combination therapy before second-line (2L) therapy including cabozantinib. We describe treatment outcomes including 1L and 2L durations of treatment (DoT) and overall survival (OS). RESULTS: Data from April 2015 to June 2022 were collected on 281 patients from nine UK centres. Median 1L DoT was 2.3 months for CPI-CPI therapy (n = 171) and 5.0 months for TKI-CPI therapy (n = 58). After 1L CPI-CPI or TKI-CPI therapy, median 2L DoT was 5.8 versus 4.2 months, respectively, for cabozantinib (n = 163), and 3.8 versus 2.4 months for other therapies (n = 118); median 2L OS was 15.2 and 15.3 months, respectively, for cabozantinib, and 14.6 and 24.2 months for other therapies. CONCLUSION: DoT for 2L treatment was numerically better for cabozantinib than for other therapies, and after 1L CPI-CPI therapy than after 1L TKI-CPI therapy. Median OS was similar for 2L cabozantinib and other 2L therapies, and median OS for 2L cabozantinib was similar after both 1L therapy types. These results demonstrate the antitumour effect of 2L therapies, including cabozantinib, after 1L CPI-based combination treatment, regardless of whether 1L CPI-CPI or TKI-CPI therapy is used.
RESUMO
Non-small cell lung cancer (NSCLC) occasionally develops in younger, fertile patients. This early-onset NSCLC tends to have more oncogenic driver mutations than in aged patients. Among early-onset NSCLC patients, pregnancy is very rare. However, there are some patients who were able to balance tyrosine kinase inhibitor (TKI) administration and pregnancy. Here, we report a case of a pregnancy under alectinib hydrochloride (a second-generation anaplastic lymphoma kinase (ALK)-TKI) administration throughout the entire gestational period for ALK-rearranged metastatic lung adenocarcinoma. The patient was an Asian female in her early 20s who became aware of her pregnancy after diagnosis and the start of alectinib administration. She intended to have the baby despite the necessity of continuing her treatment and the unknown risks involved. A multidisciplinary team (thoracic surgeon, obstetrics, pediatrics, and so on) was organized to support the patient, baby, and family. There were no obvious signs of tumor progression during pregnancy. She gave birth at 41 weeks and one day of gestation. There was no placental metastasis. Alectinib concentration at delivery was 155 ng/mL in maternal blood, 22.1 ng/mL in umbilical cord venous blood, 20.1 ng/mL in amniotic fluid, and 11.8 ng/mL in colostrum. The baby had been exposed to alectinib throughout the entire pregnancy; however, fetal growth curve parameters remained within the normal ranges and the baby developed without anatomical or neurodevelopmental anomalies or fetal metastasis for the first 13 months of age.
RESUMO
BACKGROUND: Locoregional treatment with transarterial chemoembolization (TACE) or hepatic artery infusion chemotherapy (HAIC) and systemic targeted immunotherapy with tyrosine kinase inhibitors (TKI) and programmed cell death protein-1 (PD-1) inhibitors in the treatment of unresectable hepatocellular carcinoma (uHCC) have achieved promising efficacy. The retrospective study aimed to evaluate the efficacy and safety of TACE and HAIC plus TKI with or without PD-1 for uHCC. PATIENTS AND METHODS: From November 2020 to February 2024, the data of 44 patients who received TACE-HAIC + TKI + PD-1 (THKP group) and 34 patients who received TACE-HAIC + TKI (THK group) were retrospectively analyzed. Primary outcomes were overall survival (OS) and progress-free survival (PFS), and secondary outcomes were objective response rate (ORR), disease control rate (DCR), conversion rates, and adverse events (AEs). RESULTS: A total of 78 patients were recruited in our single-center study. The patients in THKP group had prolonged median OS [25 months, 95% confidence interval (CI) 24.0-26.0 vs 18 months, 95% CI 16.1-19.9; p = 0.000278], median PFS [16 months, 95% CI 14.1-17.9 vs 12 months 95% CI 9.6-14.4; p = 0.004] and higher ORR (38.6% vs 23.5%, p = 0. 156) and DCR (88.6% vs 64.7%, p = 0.011) compared with those in THK group. Multivariate analysis showed that treatment option and alpha-fetoprotein (AFP) level were independent prognostic factors of OS and PFS. The frequency of AEs were similar between the two groups. CONCLUSIONS: The THKP group had better efficacy for uHCC than the THK group, with acceptable safety.
