The aim of this study is to explore the role of the IL-10/STAT3 pathway in the upregulation of natural killer group 2, member D (NKG2D) ligands (MICA and ULBP2) induced by Bruton's tyrosine kinase (BTK) inhibitors in non-germinal center B-cell-like diffuse large B-cell lymphoma cells. The expression levels of NKG2D ligands and the IL-10/STAT3 pathway in SUDHL4, U2932, and OCI-LY3 cells were analyzed using western blotting. After stimulation of the B-cell receptor signaling pathway with IgM antibodies, the expression levels of NKG2D ligands, as well as IL-10 and phosphorylated STAT3 (p-STAT3) were significantly reduced. In contrast, treatment with ibrutinib produced effects opposite to those induced by IgM antibodies. Additionally, treatment of U2932 and OCI-LY3 cells with the STAT3 inhibitor (STAT3-IN-1) led to an increase in NKG2D ligand expression and a decrease in IL-10 levels. When IL-10 neutralizing antibodies were introduced, p-STAT3 levels decreased, and NKG2D ligand expression increased. Similar outcomes were observed when the BTK inhibitors ACP-196 and BGB-3111 were administered. Our findings suggest that the IL-10/STAT3 pathway plays a key role in the upregulation of NKG2D ligands induced by BTK inhibitors in U2932 and OCI-LY3 cells.

Tumors with homologous recombination deficiency (HRD) can benefit from treatment with poly ADP-ribose polymerase inhibitors (PARPi). However, the methods for identifying HRD vary and are controversial. Several DNA repair genes in the homologous recombination repair pathway may be linked to PARPi susceptibility, and studies are underway to identify biomarkers that can predict the response to PARPi. We present a case of EGFR-tyrosine kinase inhibitor-resistant metastatic lung adenocarcinoma with a germline PALB2 mutation that was treated with fluzoparib (an orally administered PARPi). The treatment achieved surprising results and lasted for more than 4.5 months. Our study provided evidence that metastatic lung adenocarcinoma with germline PALB2 could benefit from PARPi, which improves patient outcomes.

Herein, we report a case of occult epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma complicated by prostatic metastasis. A 75-year-old male with >30 years of smoking history presented with lower back pain as the initial symptom. Respiratory symptoms, including cough and sputum production, were absent. PET-computed tomography revealed the presence of bone and prostatic metastases, without any lung abnormalities. Biopsies of the space-occupying bone and metastatic lesions suggested that the metastases originated from primary lung adenocarcinoma. Genetic testing indicated EGFR 21L858R(+). The patient had an abnormal serum carcinoembryonic antigen level but a normal prostate-specific antigen level. Following a multidisciplinary discussion, a diagnosis of occult primary lung adenocarcinoma complicated by bone and prostatic metastases (TxN0M1b, Stage IVB) was considered. Following targeted therapy with oral osimertinib, the patient achieved a partial response, with alleviation of pain symptoms alleviated and normalization of carcinoembryonic antigen levels. In the absence of tissue biopsy, such cases can often be misdiagnosed as prostate cancer complicated by multiple bone metastases. Hence, the present case highlights the importance of comprehensive diagnostic testing, including tissue biopsy, to accurately identify the underlying cause of metastatic disease.

The combination of anlotinib with immune checkpoint inhibitors (ICIs) has become a common treatment modality in clinical practice. However, the optimal dose of anlotinib to use remains unclear. We collected patients with advanced non-small cell lung cancer (NSCLC) who received programmed cell death-1 blockade combined with different dose of anlotinib as second-line or later line therapy. Subsequently, the efficacy and safety of the combination therapy as well as subgroup analyses of different doses of anlotinib were analyzed. Cox regression was performed to analyze significant factors correlated with progression-free survival (PFS) and overall survival (OS). A total of 50 eligible patients with NSCLC who received anlotinib combined with ICIs therapy were included, of which 27 received low-dose anlotinib (8 mg), and 23 were administered high-dose anlotinib (12 mg). The median PFS (mPFS) and the median OS (mOS) for all patients were 8.3 months [95% confidence interval (CI): 6.3-10.3] and 17.6 months (95% CI: 16.5-18.7), respectively. Subgroup analyses showed that patients treated with 8 mg of anlotinib plus ICIs had significantly longer mPFS than those treated with 12 mg of anlotinib plus ICIs (8.7 vs 6.7 months, P = 0.016). The overall incidence of adverse events was 68.0%, and the most common adverse events of all grades were hypertension. Meanwhile, the incidence of adverse events was higher for 12 mg of anlotinib plus ICIs than that of 8 mg of anlotinib plus ICIs (82.6 vs 55.6%, P = 0.041). Low-dose anlotinib in combination with ICIs for advanced NSCLC may be an effective and well-tolerated option.

The objective of this study is to explore the effect of adjuvant chemotherapy with toad venom injection in patients with intermediate and advanced colon cancer, in order to provide new reference drugs for clinical treatment. Prospectively, 148 patients with mid-stage to late-stage colon cancer in our hospital from January 2021 to May 2023 were selected for the study and randomly divided into two groups of 74 cases each. The control group was treated with FOLFOX4 chemotherapy, and the observation group was treated with four consecutive chemotherapy cycles based on the control group combined with toad venom injection. The treatment effects, adverse reactions, quality of life improvement rate, prognosis and cellular immune indexes [natural killer (NK) cells, CD4 + /CD8 + , CD4 + , CD3 + ], phosphatase tensin gene ( PTEN ), phosphatidylinositol-3-kinase (PI3k), and serine threonine protein kinase (pAKT) protein expression before and after treatment were counted in the two groups. The total effective rate of treatment in the observation group was 58.11% (43/74) after four cycles of chemotherapy, which was higher than that in the control group of 41.89% (31/74) ( P < 0.05). After two cycles of chemotherapy and four cycles of chemotherapy, PTEN , CD4 + /CD8 + , CD4 + , CD3 + , and NK cells in peripheral blood were higher in the observation group than in the control group, and PI3k and pAKT were lower than in the control group ( P < 0.05). There was no statistically significant difference in the rate of adverse reactions in the observation group compared with the control group ( P > 0.05); the improvement rate of quality of life in the observation group was better than that in the control group after four chemotherapy cycles of treatment ( P < 0.05); the survival rate was 75.00% (54/72) in the observation group compared with 54.29% (38/70) in the control group at 1-year follow-up. Toad venom injection adjuvant chemotherapy is effective in treating patients with intermediate and advanced colon cancer, which can upregulate PTEN level, inhibit PI3k and AKT expression, and improve immune function and quality of life of patients, thus improving prognosis.

Third-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are the first-line treatment of choice for patients with EGFR-mutant advanced non-small cell lung cancer (NSCLC). However, patients treated with these inhibitors eventually develop resistance. One of the most common mechanisms is the emergence of the EGFR C797S mutation. Whether first-generation EGFR inhibitors (e.g. icotinib or gefitinib) can sustainably control EGFR-sensitive mutations/C797S NSCLC following third-generation EGFR inhibitor treatment remains insufficiently reported. Our case report discusses a female patient with advanced lung adenocarcinoma carrying an EGFR exon 19 E746_A750delELREA mutation who received almonertinib as first-line treatment and developed C797S resistance during therapy. The patient was subsequently treated with a double dose of icotinib for 8 months until disease progression occurred, along with the development of an EGFR exon 20 T790M point mutation and TP53 mutation. This case provides clinical evidence suggesting that first-generation EGFR-TKIs may be an effective treatment strategy for patients with acquired EGFR 19del/C797S resistance following EGFR TKI therapy.

Tumor-infiltrating lymphocytes (TILs) often have upregulated expression of immune checkpoint receptors, such as programmed cell death 1 (PD-1) and lymphocyte-activation gene 3 (LAG-3). Patients treated with antibodies targeting PD-1 or its ligand (PD-L1) can develop resistance or relapse, with LAG-3 upregulation on T cells being one possible mechanism. FS118 is a tetravalent, bispecific antibody comprising a full-length IgG 1 anti-PD-L1 antibody with bivalent LAG-3-binding capability in the fragment crystallizable region. Here we demonstrate how the structure of FS118 is important for its function. We generated variants of FS118 and tested their ability to mediate LAG-3 shedding using staphylococcal enterotoxin B assays, antigen recall assays, and soluble LAG-3 ELISAs. Mediated by metalloproteases ADAM10 and ADAM17, FS118 induced shedding of LAG-3 from the surface of both CD4 + and CD8 + T cells. We also determined the effect of surrogate antibodies on immune cell LAG-3 expression and proliferation in syngeneic mouse models. In vivo , the bivalent LAG-3 binding sites of a mouse surrogate of FS118 and their location in the fragment crystallizable region were important for eliciting maximal reduction in LAG-3 levels on the surface of TILs, as variants with a single LAG-3 binding site in the fragment crystallizable region, or with reversed orientation of the LAG-3 and PD-L1 binding sites, were less efficient at inducing shedding. We also show that PD-L1, not PD-1, binding drives the LAG-3 reduction on TILs. We hypothesize that the LAG-3 bivalency in the fragment crystallizable region of FS118 allows LAG-3 clustering, which optimizes cleavage by ADAM10/ADAM17 and thus shedding.

The novel and highly selective anaplastic lymphoma kinase ( ALK ) inhibitor iruplinalkib showed potent activity and manageable safety profiles in patients with ALK -rearranged non-small cell lung cancer (NSCLC). However, the evidence of iruplinalkib for uncommon ALK double fusion and secondary G1202R resistance mutation is limited. Here, we report a case of a 36-year-old male with metastatic NSCLC harboring uncommon TTC7A - ALK and EML4 - ALK double fusion. Alectinib as first-line therapy showed partial response, with a progression-free survival (PFS) of 20 months. When his disease progressed, the ALK secondary G1202R resistance mutation was identified. His metastatic paraesophageal lymph node decreased during iruplinalkib treatment, achieving an ongoing PFS benefit for 10 months. Treatment-related adverse events of iruplinalkib were grade 1 hypercholesterolemia and hypertriglyceridemia. The modeling simulation revealed that the G1202R mutation exerted little effect on the binding of iruplinalkib. Iruplinalkib showed potency to G1202R because of its unique chemical structure and removal of steric clashes, which might be a promising option for ALK -rearranged NSCLC patients with G1202R resistance mutation.

The objective of this study is to assess the differential expression of ferroptosis suppressor protein 1 (FSP1) in relation to clinical features, platinum resistance, and recurrence in epithelial ovarian cancer (EOC). In addition, the potential significance of FSP1 in EOC as a predictor of platinum resistance and recurrence in EOC was explored. Patients with pathologically confirmed EOC who underwent surgical treatment were included in this analysis. Immunohistochemistry was employed to evaluate FSP1 expression in ovarian tissues, with quantitative analysis performed on the samples. Clinical data were collected during follow-up, and patients were categorized according to platinum resistance and recurrence criteria. Statistical analysis was conducted using SPSS version 27.0. A total of 40 tissue samples from patients with EOC were analyzed, along with 21 samples from benign ovarian tumors and 20 samples from normal ovarian tissues. The expression of FSP1 was significantly higher in the EOC group compared to both benign and normal tissue groups. Meanwhile, the expressions of FSP1 were higher in groups with clinically advanced stages, high-grade carcinoma, presence of cancerous ascites, lymph node metastasis, and in the clear cell EOC group, compared to those with clinically early stages, low-grade carcinoma, absence of cancerous ascites, no lymph node metastasis, and other pathological subtypes. A positive linear correlation was identified between FSP1 expression in EOC tissues and serum levels of CA125 and human epididymis protein 4 at the time of diagnosis. The elevated expression of FSP1 is positively correlated with serum CA125 and human epididymis protein 4 levels at the time of diagnosis, which is a risk factor for EOC drug resistance and recurrence. These findings suggest that FSP1 may serve as a valuable biomarker for predicting platinum resistance and recurrence in patients with EOC.

This study aimed to screen the changes after overexpression of dCTP pyrophosphatase 1 (DCTPP1) in human gastric adenocarcinoma cells (AGS) cells by proteome and transcriptome sequencing. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed to explore the functional significance of the differentially expressed DCTPP1 in gastric cancer (GC). Cell Counting Kit-8 (CCK-8) assay was used to detect the proliferation of cells. Western blot was used to detect the expression of proteins. A total of 28 genes that were significantly associated with DCTPP1 overexpression and had prognostic value were screened by Cox regression analysis. The results of gene set enrichment analysis showed that the genomes of patients with subtype A exhibited significant enrichment in pathways such as DNA repair, pyrimidine synthesis, and glucose metabolism. The tumor immune dysfunction and exclusion and The Cancer Immunome Atlas databases showed that patients with type A GC were better candidates for immunotherapy than patients with type B GC. Furthermore, the CCK-8 assay indicated significantly enhanced proliferative activity after overexpressing DCTPP1 in AGS cells, corroborating the findings from the bioinformatic analysis. The data suggest a potential association between DCTPP1 expression and both the prognosis of GC patients and the efficacy of immunotherapy. These findings offer valuable insights for the potential optimization of therapeutic strategies in gastric cancer.

Immune checkpoint blockage (ICB) therapy has shown minimal effectiveness in anaplastic lymphoma kinase (ALK)-positive nonsmall cell lung cancer (NSCLC) regardless of Programmed death-ligand 1 expression. ALK fusion accompanied by mismatch repair deficiency or microsatellite instability-high (MMRd/MSI-H) and high tumor mutation burden (TMB-H) are extremely rare in NSCLC, and the efficacy of ALK inhibitors or ICB-based therapies is unclear. Here, we report the case of a 60-year-old female patient with metastatic lung adenocarcinoma accompanied by EML4-ALK fusion, TMB-H, MMRd/MSI-H, and pathogenic mutations in TP53, MLH1, and STK11. The patient experienced progression on initial iruplinalkib and subsequent alectinib therapy within 5 months. After the failure of third-line therapy with cisplatin-pemetrexed combined with bevacizumab, she received sintilimab plus anlotinib which led to a progression-free survival of 6.5 months. She received sintilimab combined with albumin-paclitaxel plus carboplatin and achieved partial response after 6 months. She developed adverse events after one cycle of sintilimab plus albumin-paclitaxel treatment. Then she was continued with sintilimab plus anlotinib as a maintenance therapy due to intolerance to chemotherapy. After progression on ICB-based therapy, the patient was treated with lorlatinib and still under follow-up with overall survival of more than 3 years. Our findings highlight the therapeutic potential of ICB-based regimens in patients with MSI-H and ALK-rearranged NSCLC.

This study aimed to evaluate the efficacy and safety of sintilimab combined with oral vinorelbine in newly diagnosed patients with stage IIIb to IV nonsmall cell lung cancer (NSCLC) who had an Eastern Cooperative Oncology Group performance status (PS) of 2 or over 75 years of age during the initial treatment. This prospective single-center single-arm study enrolled patients with histologically confirmed NSCLC. Eligible patients were administered sintilimab and vinorelbine. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included objective response rate (ORR) and disease control rate (DCR). Furthermore, this study assessed indicators of treatment response and safety. From September 2020 to December 2023, 60 eligible patients were enrolled in the Respiratory Department of Shanxi Cancer Hospital. Following treatment, PFS was 9.1 months, and ORR and DCR were 39.6 and 63.79%, respectively. In addition, there was a reduction in blood tumor marker levels and enhanced immune function. Adverse reactions had a relatively low incidence and primarily consisted of grade 1-2 cases. Sintilimab plus oral vinorelbine showed promising efficacy and safety as a first-line treatment strategy for patients with NSCLC with PS 2 or elderly patients. It also optimizes immune function in patients with NSCLC.

FOLFOX combined with cetuximab is a recommended first-line treatment regimen for RAS/BRAF wild-type metastatic colorectal cancer (mCRC). CAPEOX combined with cetuximab differs from the FOLFOX regimen by using oral capecitabine instead of continuous infusion of fluorouracil, offering greater convenience and cost-effectiveness with higher patient acceptance. However, the comparative efficacy of these two regimens remains debatable, necessitating further evidence to explore any differences in their efficacy. This study collected medical records of mCRC patients who were treated with CAPEOX or FOLFOX combined with cetuximab from 1 October 2021 to 16 October 2023 at Harbin Medical University Cancer Hospital and the First Hospital of Shanxi Medical University. Eligible patients were selected based on inclusion criteria and followed up through the hospital's follow-up system and telephone interviews. Kaplan-Meier survival analysis and Cox proportional hazards regression analysis were used to assess patients' progression-free survival (PFS) and overall survival (OS). A total of 71 eligible patients were enrolled in this study; 43 patients received CAPEOX combined with cetuximab (Group A, n = 43), and 28 patients received FOLFOX combined with cetuximab (Group B, n = 28). The two groups achieved similar median PFS (mPFS) and median OS (mOS), with mPFS of 18 months and 12 months, respectively ( P = 0.23), and mOS of 33 months and 20 months, respectively ( P = 0.21), with no statistically significant differences. The results of this study demonstrated that CAPEOX combined with cetuximab is an equally viable option for first-line treatment of RAS/BRAF wild-type mCRC as FOLFOX combined with cetuximab.

We present the case of a young woman diagnosed with chronic myeloid leukemia who began de-novo treatment with nilotinib, which led to increased plasma levels of total bilirubin and QT interval. An evaluation of the genetic profile of uridine diphosphate glucuronosyltransferase was made, as nilotinib inhibits the activity of this enzyme causing hyperbilirubinemia, with higher risk in slow metabolizers, such as those ones with *6/*6 genotype. This type of patient can be identified by genetic profiling, and adjustment in the dose of nilotinib could be made to avoid tyrosine kinase inhibitor switching.

Thyroid cancer is one of the most common endocrine gland malignancies in China. During gene transcription, the bromodomain and extraterminal domain (BET) proteins perform epigenome interpretation tasks. Bromodomain-containing protein 9 (BRD9) is one of the BET family members. Increasing evidence has implicated that BRD9 plays significant roles in multiple malignancies. However, its role in thyroid cancer is still not fully understood. In this research, our results demonstrated that high expression of BRD9 can facilitate the malignant phenotype of thyroid cancer cell lines, while low expression of BRD9 can impede the malignant phenotype of thyroid cancer cell lines. Pharmacologically, I-BRD9 treatment inhibits the proliferation and promotes the rate of apoptosis in thyroid cancer cell lines. Moreover, our results also revealed that BRD9 promoted xenograft tumor growth. In addition, our study showed that the expression of mitogen-activated protein kinase (MAPK)/extracellular signal-regulated protein kinase (ERK) pathway-related proteins was decreased in BRD9 knockdown thyroid cancer cells, such as Raf, ERK, p-ERK, c-Fos, and c-Myc, which could be significantly reversed by overexpressing the BRD9 in different thyroid cancer cells. After the specific inhibitor of ERK (SCH772984) was applied to thyroid cancer cells (BCPAP cells) overexpressing the BRD9 gene, the results suggested that SCH772984 reverses the high expression of MAPK/ERK pathway-associated protein in BCPAP cells (over-expression BRD9 cells). In conclusion, this study demonstrated that BRD9 was highly expressed in serum and malignant tumor tissues of thyroid cancer patients and further promoted the development of the malignant phenotype of thyroid cancer by activating the MAPK/ERK signaling pathway.

We aimed to explore the role of ikarugamycin (IKA) in breast cancer, its connection with hexokinase-2 (HK-2) repression, and tissue factor (TF). This study sought to extend the role of HK-2 as a TF activator in a comprehensive analysis of these interactions from the enzyme, gene, and protein levels. The investigation was performed with MDA-MB-231 and MCF-7 breast cancer lines. The oxidative stress index (OSI), lactate production, and HK activity were assessed using colorimetric assays. Western blot and quantitative PCR analyses were performed to determine HK-2 and TF expressions. Prothrombin time Tests additionally assessed the effect of IKA therapy on TF activation. Three over four significantly downregulated genes were identified after a specific analysis of the IKA's effect on HK-2 and TF in breast cancer cell lines. In the IKA treatment group, lactate production was markedly reduced ( P < 0.05) and hexokinase activity was found to be reduced in all groups ( P < 0.05, <0.01). Paclitaxel cytotoxicity independently causes lower OSI in all IKA-treated groups as compared to controls even though OSI is elevated in IKA groups compared to control. Molecular analysis results demonstrated significantly downregulated HK-2 and TF expressions at the protein level ( P < 0.05, P < 0.01). Partial thromboplastin time results also showed that IKA-treated cells had longer TF activation duration. A potential indirect association of HK-2 inhibition and TF regulation in breast cancer cells is put forward in this study by presenting IKA's bioactivation of breast cancer in all gene, protein, and enzyme levels.

Anlotinib, a tyrosine kinase inhibitor, has shown encouraging antitumor activity in platinum-resistant/refractory ovarian cancer. The efficacy of anlotinib as maintenance therapy in advanced ovarian cancer remains unclear. Therefore, we designed this study to evaluate the efficacy and safety of anlotinib maintenance therapy following first-line treatment with paclitaxel and platinum-based chemotherapy in advanced ovarian cancer. In this single-arm, phase II clinical trial, patients with newly diagnosed advanced ovarian cancer were received anlotinib monotherapy as maintenance therapy once after a response to platinum-based chemotherapy until tumor progression or intolerable toxicity. The primary endpoint was progression-free survival. From April 2020 to June 2021, 24 patients were enrolled in this study. The median follow-up was 40.17 months (interquartile range, 32.40-47.93 months). Of 21 patients with efficacy value, the median progression-free survival and median overall survival were 15.8 months (95% confidence interval, 6.8-24.8 months) and 43.8 months (95% confidence interval, 25.45-62.15 months). The quality-adjusted progression-free survival was 14.4 months and there were no observed treatment-related deaths or serious treatment-emergent adverse events, demonstrating the safety of anlotinib in maintenance therapy. Anlotinib shows significant potential as a first-line maintenance therapy for advanced ovarian cancer, extending survival and providing a reliable treatment option.

In gastric cancer, the relationship between human epidermal growth factor receptor 2 (HER2), the cyclic GMP-AMP synthase-stimulator of the interferon genes (cGAS-STING) pathway, and autophagy remains unclear. This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment. Through lentiviral transfection, cell counting kit-8 assays, colony formation, transwell migration, scratch assays, and siRNA, we found that HER2 overexpression suppresses the cGAS-STING pathway, inhibits autophagy, and enhances the migratory ability of gastric cancer cells. In contrast, HER2 knockdown activates the cGAS-STING pathway, promotes autophagy, and reduces cell migration. We further observed that the inhibition of autophagy using chloroquine (CQ) increases the migration ability of HER2-overexpressing cells. Moreover, interfering with STING expression reversed the migration defects caused by HER2 knockdown, underscoring the critical role of the cGAS-STING pathway in HER2-regulated cell migration. We also revealed that high STING expression in gastric cancer is significantly associated with poor prognosis. STING expression was identified as an independent prognostic factor for survival (hazard ratio, 1.942; 95% confidence interval, 1.06-3.54; P = 0.031). These results highlight the importance of HER2-driven regulation of autophagy through the cGAS-STING pathway in gastric cancer progression and its potential as a therapeutic target.

Uncommon atypical mutations account for 10-15% of all epidermal growth factor receptor (EGFR) activating mutations in nonsmall-cell lung cancer (NSCLC). Tumors harboring rare EGFR mutations show highly heterogeneous responses to EGFR tyrosine kinase inhibitors (TKIs). There is insufficient clinical evidence for uncommon types of EGFR mutations, especially those with compound EGFR mutations. In addition, for those with uncommon compound EGFR mutations, few studies have focused on acquired resistance mechanisms and subsequent treatment strategies after disease progression on EGFR-TKIs. Here, a 66-year-old smoking male was diagnosed with lung adenocarcinoma accompanied by pleural metastasis. A rare L833V/H835L compound mutation in exon 21 of EGFR was detected in tumor biopsy by next-generation sequencing. Afatinib was used as first-line therapy and showed favorable efficacy. The patient continued afatinib treatment for a duration of 24 months. A new T790M mutation was detected with a rebiopsy after progression on afatinib. Then the patient received cryoablation therapy and a third-generation EGFR-TKI, furmonertinib. Our case suggests that a comprehensive screening for EGFR mutations should be conducted before and during treatment in clinical practice, and afatinib and furmonertinib could be first- and second-line treatment options in NSCLC patients harboring EGFR L833V/H835L mutations.

Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer with limited therapeutic options and poor prognosis. In this study, we explored the therapeutic potential of BGJ398, a selective fibroblast growth factor receptor (FGFR) inhibitor, alone and in combination with standard chemotherapy (cisplatin and paclitaxel) in SCLC. High-throughput screening of kinase inhibitors was performed on three SCLC cell lines (NCI-H446, NCI-H69, and NCI-H182), identifying BGJ398 as one of the most potent and selective inhibitors. BGJ398 demonstrated significant synergy with cisplatin and paclitaxel in vitro , as indicated by combination index values below 1. In vivo , combination treatments significantly inhibited tumor growth and extended survival in SCLC xenograft models compared to monotherapies. Notably, the combination of BGJ398 with cisplatin exhibited the most pronounced tumor suppression and survival benefits. Immunohistochemistry analysis confirmed that BGJ398 effectively inhibited FGFR signaling pathways, reducing levels of phosphorylated FGFR, protein kinase B, signal transducer and activator of transcription 3, and extracellular signal-regulated kinase. These findings suggest that BGJ398, particularly in combination with chemotherapy, holds significant promise as a treatment strategy for SCLC, providing enhanced anti-tumor efficacy and improved survival outcomes.
