  • This study investigated the antiproliferative effects of luteolin (LUT) and its potential to modify the response of breast cancer (BC) cells to ionizing radiation (IR). LUT effects alone or with IR were evaluated in MCF-7 and MDA-MB-231 cells using clonogenic and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. Apoptosis and cell cycle distribution were assessed by flow cytometry, while reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blotting were used to determine apoptosis-related gene and protein expression. LUT reduced the clonogenic survival and metabolic activity in both BC cell lines. In MCF-7 cells, combined LUT and IR treatment produced a greater reduction in metabolic activity and clonogenic survival than either treatment alone, whereas no comparable effect was observed in MDA-MB-231 cells. LUT induced apoptosis in both cell lines. Cell cycle analysis indicated G2/M phase accumulation, reaching statistical significance in MDA-MB-231 cells. In MCF-7 cells, LUT decreased BCL2 and MCL1 gene expression, with a further reduction following combined LUT and IR treatment. Consistently, BCL-2 protein levels were reduced in MCF-7 cells. In MDA-MB-231 cells, LUT modulated the expression of selected anti-apoptotic genes. Overall, these findings demonstrate cell line-dependent effects of LUT and suggest that its ability to modify the response to IR may depend on the molecular characteristics of BC cells.

    Introduction Radiotherapy is a vital therapeutic option in the treatment of breast cancer nowadays. However, a major obstacle to the full effectiveness of radiation therapy is still the radioresistance of cancer cells. Various studies have proven sulforaphane's (SFN) beneficial effects against cancer and its possible utilization as a radiosensitizer in radiotherapy. This study aimed to investigate whether SFN has a radiosensitizing effect on breast cancer cells.

    Material and methods The anticancer efficiency of SFN and radiosensitizing effect in MCF-7 and MDA-MB-231 cell lines were assessed by the MTT assay. Using a flow cytometric assay, the apoptosis level and changes in the cell cycle were measured. RT-qPCR and Western blot analysis were used to determine BCL-2 and BCL-XL genes expresion and proteins level.

    Results According to our results, SFN reduced the viability of cells, and combining SFN with radiation therapy (IR) caused much greater anticancer effects on cells. SFN+IR was shown to enhance the number of cells in the G2/M phase and the percentage of cells going through apoptosis. SFN reduced the expression of apoptosis-relative genes BCL-2 and BCL-XL. Consistent with this data, Western blot analysis revealed that BCL-2 and BCL-XL protein levels were decreased in tested cells. As a result of the combination treatment, the downregulation of the BCL-2 protein was observed only in MDA-MB-231 cells.

    Conclusions These results indicate that SFN acts as a radiosensitizer by enhancing apoptotic cell death and reducing anti-apoptotic genes in breast cancer cells.

  • Cancer remains a major health burden in Lithuania, emphasizing the importance of effective undergraduate oncology education. This paper describes the structure and key features of the integrated oncology curriculum at the Lithuanian University of Health Sciences (LSMU). Oncology teaching is embedded within a six-year medical programme, combining early exposure through biomedical sciences with focused clinical training in a mandatory Year IV Hematology and Oncology module. Teaching methods include lectures, small-group seminars, and supervised ward-based learning, with a strong emphasis on case-based discussion and clinical reasoning. Students are introduced to principles of cancer diagnosis, staging, treatment, and multidisciplinary decision-making. Simulation and practical skills training further support clinical competence. Assessment includes written examinations and clinical case assignments, aligned with programme-level evaluations such as OSCE. Teaching is delivered in a multidisciplinary academic environment with structured quality assurance and continuous student feedback. This model provides a clinically grounded and integrated approach to cancer education, ensuring continuity from undergraduate medical education to postgraduate specialist training. Expanding hands-on clinical exposure, strengthening communication training, and incorporating emerging technologies such as artificial intelligence may further enhance the curriculum.

    Piktybinių navikų plaučiuose terminė abliacija kontroliuojant kompiuterine tomografija: klinikinio efektyvumo, saugumo ir poveikio kvėpavimo funkcijai tyrimas
    [Computed Tomography Guided Thermal Ablation of Malignant Lung Lesions: a Study of Clinical Efficacy, Safety and Impact on Respiratory Function]

    Plaučių vėžys išlieka pagrindinė onkologinio mirtingumo priežastis, o plaučiai dažnai tampa ir kitų piktybinių navikų metastazių vieta. Nemaža dalis pacientų dėl gretutinių ligų yra neoperabilūs. Šiems pacientams svarbi alternatyva – kompiuterine tomografija kontroliuojama terminė abliacija (TA), leidžianti sunaikinti naviką maksimaliai tausojant plaučių audinį. Tyrimu siekiama išsamiai įvertinti terminės abliacijos saugumą bei jos daromą įtaką pacientų kvėpavimo funkcijai ir bendrai gyvenimo kokybei, lyginant šį metodą chirurgine rezekcija ir stereotaksine radioterapija. Tyrimo rezultatai parodė, kad TA yra saugus ir efektyvus gydymo metodas. Lyginant su chirurgija, TA pasižymi trumpesne hospitalizacija, mažesniu komplikacijų dažniu bei geresniu plaučių funkcijos ir perfuzijos išsaugojimu, pacientai greičiau atgauna funkcinį aktyvumą išlaiko geresnę gyvenimo kokybę, patiria mažiau skausmo išlaikant aukštą vietinę ligos kontrolę. Rekomenduojama terminę abliaciją svarstyti kaip efektyvią radikalaus gydymo alternatyvą neoperabiliems, sunkių gretutinių ligų turintiems pacientams. Nustatyta, kad po plaučio perkutaninių intervencijų punkcijos kanalo embolizavimas autologiniu kraujo krešuliu sumažina poprocedūrinio pneumotorakso riziką, tad rekomenduojama šią metodiką taikyti klinikinėje praktikoje. Planuojant gydymą ypač svarbu pasitelkti hibridinę plaučių perfuzijos scintigrafiją, padedančią tiksliai įvertinti ir prognozuoti regioninius plaučių perfuzijos pokyčius.

    Nepaisant pažangių diagnostinių technologijų, gerklų vėžio išplitimas į nesukaulėjusią skydinę kremzlę išlieka reikšmingu diagnostiniu iššūkiu, turinčiu įtakos gydymo taktikos ir apimties pasirinkimui. Atsižvelgiant į pastaruoju metu didėjančias kontrastinio ultragarsinio tyrimo (KUT) panaudojimo galimybes, šio tyrimo tikslas — nustatyti KUT kokybinio ir kiekybinio vertinimo diagnostinę vertę tiriant gerklų plokščiųjų ląstelių karcinomos išplitimą į nesukaulėjusią skydinę kremzlę, lyginant su pooperaciniu histopatologiniu tyrimu. Į tyrimą įtrauktiems pacientams kompiuterinės tomografijos (KT) tyrimu buvo įtartas ar nustatytas gerklų karcinomos išplitimas į nesukaulėjusią skydinę kremzlę, kuris taip pat tirtas KUT ir magnetinio rezonanso tomografijos (MRT) tyrimu. Rezultatai parodė, kad vertinat gerklų karcinomos išplitimą į nesukaulėjusią skydinę kremzlę, kokybinis KUT vertinimas turėjo aukštą diagnostinę vertę, kuri statistiškai reikšmingai nesiskyrė nuo histopatologinio tyrimo rezultatų, o KUT derinimas su KT ir ypač su MRT padidino diagnostinį specifiškumą ir tikslumą. Kiekybiniai KUT parametrai taip pat pasižymėjo aukšta diagnostine verte ir leido patikimai patvirtinti arba paneigti gerklų karcinomos išplitimą į skydinę kremzlę. Apibendrinant, gauti rezultatai rodo, kad KUT yra diagnostiškai vertingas papildomas radiologinis tyrimas tais atvejais, kai gerklų vėžio išplitimas į nesukaulėjusią skydinę kremzlę po rutininių KT ir MRT tyrimų išlieka neaiškus.

    Laryngeal cancer is a relatively uncommon malignancy with predisposing genetic factors that remain unclear. Single-nucleotide polymorphisms (SNPs) in genes involved in innate immune signaling may contribute to the development and progression of laryngeal carcinoma. This study aimed to evaluate the association of TLR4 (rs7037225, rs11536889, rs7037117) and MYD88 (rs7744, rs6853) polymorphisms with the risk of laryngeal squamous cell carcinoma (LSCC), as well as its clinical and pathological characteristics and survival. A retrospective case–control study involving 172 LSCC patients and 220 healthy controls was conducted. Genotyping was performed using real-time PCR from venous blood samples. MYD88 rs7744 was significantly associated with tumor size and lymph node involvement. Survival analysis showed a significant association between rs7744 and recurrence-free survival (RFS), with the AG and GG genotypes linked to poorer outcomes. Conversely, carriers of the TLR4 rs7037225 CT genotype showed significantly improved RFS, with p ranging from 0.024 to 0.037 across models. Considering the significant roles of TLR4 and MYD88 in Toll-like receptor signaling, these findings may reflect the involvement of innate immune pathways in LSCC progression. In summary, MYD88 rs7744 was associated with clinicopathological features and RFS, while TLR4 rs7037225 appeared to have a potential protective effect on survival.

    Background and Objectives Breast cancer (BC) is a biologically heterogeneous disease with diverse molecular subtypes and clinical outcomes, strongly influenced by genetic factors. ATP-binding cassette (ABC) transporters play an important role in transmembrane processes, including drug efflux, cellular detoxification, and the maintenance of intracellular homeostasis. Variants in genes such as ABCB1 and ABCB8 may contribute to interindividual differences in tumor behavior, influencing clinicopathological characteristics and potentially affecting disease progression and treatment response. This study evaluated the association of two single nucleotide polymorphisms (SNPs), ABCB1 rs1128503 and ABCB8 rs56198402, with BC clinicopathological features. The findings aim to clarify their role in tumor biology and assess their potential as prognostic biomarkers, contributing to a better understanding of the genetic background of BC heterogeneity. Material and Method The study population comprised 170 female patients with histopathologically confirmed early-stage primary BC, aged 30 to 74 years (median age: 46 years). Clinical and tumor pathomorphological data, including tumor size, lymph node involvement, presence of metastases, degree of differentiation, estrogen (ER) and progesterone (PR) receptor status, human epidermal growth factor receptor 2 (HER2) status, disease progression, and mortality, were obtained from oncologists and the follow-up period extended until November 30, 2024. Genomic DNA was extracted from peripheral blood leukocytes using a column-based commercial DNA isolation kit in accordance with the manufacturer’s instructions. Genotyping of ABCB1 rs1128503 and ABCB8 rs56198402 was performed using TaqMan probe-based assays on the QuantStudio™ 3 Real-Time PCR System. The strength of associations between SNPs and BC clinicopathological characteristics was estimated using crude odds ratios (ORs) and corresponding 95% confidence intervals (CIs). Survival outcomes were assessed using Kaplan-Meier analysis. Statistical analysis was conducted using IBM SPSS Statistics, version 30.0.0.0, and a p-value < 0.05 was considered statistically significant. The study protocol was approved by the Kaunas Regional Biomedical Research Ethics Committee (approval numbers BE-2-10 and P1-BE-2-10/2014). Results Significant associations were identified between ABCB1 rs1128503 and PR status, metastatic disease, disease progression, and mortality. Specifically, GA genotype carriers had higher odds of progesterone receptor positivity than GG (OR=2.038; 95% CI 1.016–4.091; p=0.045), which was corroborated by allele-based analysis, showing similarly increased odds among A allele carriers (OR=1.986; 95% CI 1.034–3.816; p=0.039). Conversely, GA carriers demonstrated reduced odds of metastasis (OR=0.301; 95% CI 0.122–0.742; p=0.009), disease progression (OR=0.387; 95% CI 0.171–0.877; p=0.023), and mortality (OR=0.361; 95% CI 0.144–0.907; p=0.030). Furthermore, tumor size and lymph node involvement were also significantly associated (p-value < 0.05) with the studied genotype, indicating a protective effect against more advanced disease features. A significant difference in progression-free survival was observed across ABCB1 rs1128503 genotypes, with the GA genotype associated with more favorable outcomes (p-value < 0.05). No significant associations were found between the ABCB8 rs56198402 and clinicopathological characteristics of BC. Conclusions and Recommendations The ABCB1 rs1128503 was significantly associated with several breast cancer clinicopathological features, including progesterone receptor status, metastasis, disease progression, and progression-free survival, suggesting a potential protective effect of the GA genotype. In contrast, no significant associations were found for the ABCB8 rs56198402 variant. Further studies with larger cohorts are needed to confirm these findings and clarify the biological role of ABCB1 variants in breast cancer progression and prognosis.

    Background and Objectives Breast cancer (BC) is a heterogenous disease characterized by substantial variability in tumor biology and clinical behavior. This heterogeneity is reflected in clinicopathological features, including hormone receptor status, human epidermal growth factor receptor 2 (HER2) expression, tumor histological grade, tumor size, and disease stage, which describe tumor features and are key determinants of prognosis. Single nucleotide polymorphisms (SNPs) have been proposed as potential contributors to inter-individual differences in these tumor features and clinical outcomes; however, their role in early-stage BC remains insufficiently defined. In this study, polymorphisms in the RRP1B gene, specifically rs2838342 and rs2051407, were investigated for their potential associations with BC features and outcomes. Material and Method Study population. A total of 191 adult female patients with primary stage I-II BC were enrolled. All participants provided written informed consent, and the study was approved by the Kaunas Regional Ethics Committee for Biomedical Research (nos. BE-2-10 and P1-BE-2-10/2014). Peripheral blood samples were collected for genetic analysis. DNA extraction and genotyping. Genomic DNA was extracted from peripheral blood using a spin column-based extraction method with a commercially available kit. SNP genotyping was performed using TaqMan allelic discrimination assays on a Quanstudio 3 Real-Time PCR System. Statistical analysis. Associations between SNPs and clinicopathological features as well as binary clinical outcomes (disease progression, metastasis status, and mortality status) were evaluated using logistic regression under an additive genetic model. Both univariate and age-adjusted multivariable analyses were performed. Sensitivity analyses using alternative genetic models were conducted for selected SNPoutcome associations showing non-linear patterns in genotype distributions. Progression-free, overall, and metastasis-free survival (MFS) were analyzed using Kaplan-Meier with log-rank tests and Cox proportional hazards regression models under an additive genetic model. Multivariable Cox models were adjusted for established clinicopathological prognostic factors. To account for multiple testing, the Benjamini-Hochberg false discovery rate (FDR) correction was applied separately for clinicopathological features (n = 12), binary clinical outcomes (n = 6), and Cox models (n = 6), using p-values from fully adjusted additive models. Kaplan-Meier analyses were considered descriptive and were not included in correction. Adjusted p-values (q-values) < 0.05 were considered significant. All statistical analyses were performed using IBM SPSS Statistics 30.0.0.0. Results Genotype distributions were as follows: for rs2838342, AA 30.9% (n = 59), AG 51.8%, (n = 99), and GG 17.3% (n = 33); for rs2051407, CC 36.6% (n = 70), CT 45.5 % (n = 87), and TT 17.8% (n = 34). The minor allele frequencies were 43.2% for rs2838342 and 40.6% for rs2051407. Genotype frequencies for both SNPs were consistent with Hardy-Weinberg equilibrium (p > 0.05). In age-adjusted additive logistic regression models, rs2838342 was associated with tumor size (p = 0.022) and histological grade (p = 0.032), although neither association remained significant after correction for multiple testing. Under a recessive genetic model, rs2838342 was associated with estrogen receptor (ER) status after adjustment for age group (OR = 0.38, 95% CI 0.17-0.85, p = 0.018), suggesting a lower likelihood of ER positivity among GG homozygotes. A similar nonsignificant trend under the same genetic model was observed for rs2051407 (p = 0.072). Kaplan-Meier analyses showed no statistically significant differences in survival outcomes across genotype groups. Consistently, no associations were observed in Cox regression analyses under unadjusted or multivariable-adjusted models accounting for age and clinicopathological variables. All results remained non-significant after Benjamini-Hochberg FDR correction. Conclusions and Recommendations No statistically significant associations were observed between the studied SNPs and clinicopathological or survival outcomes after multiple testing correction. However, nominal and model-specific associations for rs2838342 indicate a potential role in tumor biology requiring validation in larger, independent cohorts.

    Background and Objectives Germline pathogenic or likely pathogenic (P/LP) variants account for 5–10% of all breast cancer (BC) cases, with a higher prevalence of 10–20% observed in specific BC molecular subtypes, such as triple-negative breast cancer (TNBC). P/LP variants in established BC susceptibility genes are associated with an increased risk of BC and may contribute to distinct tumor phenotypes and clinical outcomes. This study aimed to evaluate the distribution of germline P/LP variants and their associations with clinicopathological features and clinical outcomes in BC patients. Material and Method A total of 85 female patients with stage I-II BC, including hormone receptor-positive (HR+)/HER2-negative (HER2−) (n=60) and TNBC (n=25), were included. Inclusion criteria required complete clinicopathological data (age at diagnosis, tumor size, tumor histological grade, lymph node involvement, and clinical outcomes) and absence of clinically significant comorbidities. Exome sequencing of germline DNA from peripheral blood was performed to identify variants in 13 BC susceptibility genes (BRCA1, BRCA2, CDH1, PTEN, STK11, TP53, ATM, CHEK2, PALB2, RAD51C, RAD51D, BARD1, and NF1). Variant analysis was conducted using the Franklin platform (Qiagen), and pathogenicity was re-evaluated according to current ENIGMA, ClinGen, and CanVIG guidelines. For statistical analysis, patients were stratified into P/LP variant carriers and non-carriers. Associations with clinicopathological features and clinical outcomes were assessed, with age included as a continuous covariate for adjustment. The study was approved by the Kaunas Regional Biomedical Research Ethical Committee (Nos. BE-2-10 and P1-BE-2-10/2014). Results Overall, 11 distinct P/LP variants were identified (six in BRCA1, three in CHEK2, and one each in BRCA2 and ATM). These variants were detected in 20/85 patients (23.5%), including 10/60 (16.7%) with HR+/HER2− BC and 10/25 (40%) with TNBC. Only one HR+/HER2− BC patient carried two variants; all others had a single variant. P/LP variants were significantly associated with BC molecular subtype (p=0.021), with carriers more likely to have TNBC (OR=3.33, 95% CI 1.17−9.52, p=0.025), although this was not significant after age adjustment (p=0.158). Carrier status was also associated with tumor grade (p=0.039), disease progression (p=0.007), and distant metastasis (p=0.035), but only the association for increased risk of disease progression for patients carrying P/LP variants remained significant after age adjustment (OR=3.09, 95% CI 1.01–9.43, p=0.048). In the TNBC subgroup, P/LP variant carrier status was statistically associated with lymph node involvement (p=0.009), with carriers having higher odds of lymph node involvement, even after age adjustment (OR=15.18, 95% CI 2.01–113.35, p=0.008), although this finding should be interpreted cautiously due to the small sample size. Survival analysis showed a significant association between P/LP variant carrier status and progression-free survival (PFS) in the overall cohort (p=0.011), which was likely driven by the HR+/HER2− BC subgroup (p=0.030) but not TNBC (p=0.154). In HR+/HER2− patients, carriers had a higher risk of shorter PFS in univariate analysis (HR=2.8, 95% CI 1.05–7.54, p=0.039), which was not significant after age adjustment (p=0.084). For metastasis-free survival (MFS), a significant difference was observed in the overall cohort (p = 0.039), but not in subtype-specific analyses. Although carriers showed a higher risk of shorter MFS in univariate analysis (HR=2.41, 95% CI 1.02– 5.72, p=0.046), this did not remain significant after adjustment for age (p=0.073). Conclusions and Recommendations Germline P/LP variants were identified in a substantial proportion of BC patients, with a higher prevalence in TNBC. Although carrier status was associated with more aggressive disease features, particularly disease progression, most associations did not remain significant after adjustment for age. These findings suggest that P/LP variants may contribute to BC heterogeneity, although their independent prognostic value appears limited and requires further investigation in larger cohorts.

    Background and Objectives Breast cancer is a leading cause of cancer-related deaths globally. According to WHO data, in 2022, BC accounted for 6.8% of cancer-related deaths worldwide and 6.2% of such deaths within the Lithuanian population. One of the mechanisms underlying BC is the influence of genetic variants. High-frequency, low-penetrance genetic variants, including single nucleotide polymorphisms (SNPs), are more frequently linked to sporadic breast cancer. The epithelial-to-mesenchymal transition (EMT) is a cellular process that plays a role in embryonic development, wound healing, and tumor formation. EMT is crucial in invasion and subsequent metastasis. Snail1, encoded by the SNAI1 gene, is one of the key factors triggering EMT. In this study, we focused on SNAI1 rs8120550, rs1543442, and rs73113648 polymorphisms and their impact on various pathomorphological features and patients’ prognosis within the Lithuanian breast cancer cohort. Material and Method A total of 199 breast cancer patients were studied. The inclusion criteria were as follows: confirmed diagnosis, early BC stage (I–II), and complete medical documentation. Clinicopathological information was collected from medical records in collaboration with oncologists. Polymorphisms of interest were analyzed with real-time PCR-based genotyping. Statistical analysis was performed using SPSS (31.0.0.0). A pvalue < 0.05 was considered statistically significant. The study received approval from the Kaunas Regional Biomedical Research Ethical Committee (no. BE-2-10, no. P1- BE-2-10/2014,), and written informed consent was obtained from all participants. Results Pearson’s chi‑square analysis revealed significant associations between SNAI1 rs8120550 and disease progression (p = 0.011) and metastasis (p = 0.008). Additionally, rs73113648 was significantly associated with age group (p = 0.041), disease progression (p = 0.002), and metastasis (p = 0.002). In univariate logistic regression analysis, for SNAI1 rs73113648, the TT genotype was significantly associated with older age at diagnosis, showing lower odds compared with the CC genotype (OR = 0.247, p = 0.036). In the analysis of clinical outcomes for rs73113648, the TT genotype was statistically associated with higher odds of progression and metastasis compared with CC genotype (OR = 6.207, p = 0.001; OR = 5.952, p = 0.002, respectively). Rs8120550 demonstrated significant associations with disease progression and metastasis, where the AG genotype was associated with significantly higher odds than the AA genotype (OR = 2.718, p = 0.005; OR = 2.872, p = 0.005, respectively). The following are results after Kaplan-Meier method, which was used to evaluate the association between SNPs and PFS, MFS and OS: rs8120550 showed significant results for PFS (p = 0.012) and for MFS (p = 0.009), while rs73113648 demonstrated statistically significant associations with PFS (p = 0.001) and MFS (p = 0.004). Rs1543442 demonstrated no significant associations with any survival outcomes. In univariate Cox regression analysis, rs8120550 (AG versus AA) were associated with shorter PFS (HR = 2.323, p = 0.006) and MFS (HR = 2.529, p = 0.006), while rs73113648 (TT versus CC) was linked to even shorter PFS (HR = 3.650, p < 0.001) and MFS (HR = 3.567, p = 0.002). Conclusions and Recommendations The study revealed that SNAI1 rs8120550 and rs73113648 were significantly associated with an increased risk of disease progression and metastasis. Both SNPs were also associated with poorer PFS and MFS, with rs73113648 showing the strongest effect. These findings suggest that SNAI1 polymorphisms may have prognostic value for clinical outcomes in early-stage BC, but further studies involving a larger, independent cohort, are recommended to confirm our findings.
