Comparison of five prognostic scoring systems, the French-American-British (FAB) and World Health Organization (WHO) classifications in patients with myelodysplastic syndromes: Results of a single-center analysis.

We retrospectively studied 89 consecutive patients diagnosed with primary myelodysplastic syndrome (MDS) over a period of 10 years to (1) identify prognostic factors for overall survival (OS) and leukemia-free survival (LFS); (2) to assess and compare the Bournemouth-, Spanish-, Düsseldorf-, Lille-, and the International prognostic scoring systems (IPSS); and to (3) compare the French-American-British (FAB) and World Health Organization (WHO) classifications. The median age of patients was 63 years (range, 26-85). Karyotype analyses were done in 85 patients (96%). Median OS was 3 years; 67 patients (75%) have died, and 28 (31%) had progression to acute myeloid leukemia (AML). Major independent prognostic variables for both OS and LFS (multivariate analysis) were percentage of bone marrow (BM) blasts (P < 0.0001), and in patients with cytogenetic data available, cytogenetic risk groups by Lille-score (OS, P = 0.031/LFS, P = 0.002) and IPSS (OS, P = 0.024). All five prognostic scoring systems successfully discriminated risk groups as regards OS and LFS, but in patients with cytogenetic data available, the major independent prognostic score for OS (P < 0.0001) and LFS (P = 0.006) was the IPSS. The FAB and WHO classifications also successfully discriminated between risk groups. The new WHO subgroups [refractory cytopenia with multilineage dysplasia (RCMD), with (RCMD-RS) or without ringed sideroblasts] showed a significantly (P = 0.0454) different prognosis for OS, but not for LFS (P = 0.0839), in comparison to the subgroups having erythroid dysplasia only (RA/RARS). Risk stratification into refractory anemia with excess blast-I (RAEB-I) and RAEB-II tended to yield different prognoses for OS and LFS. The 5q-minus syndrome strongly predicted for a good prognosis. In patients treated with the demethylating agent decitabine (n = 24), IPSS "poor risk" cytogenetics were unable to predict for the expected worse prognosis when compared to "intermediate-risk" cytogenetics. In conclusion, we confirm in a single-center patient cohort that the use of the WHO classification improves the predictive value of the FAB classification and that, in patients with cytogenetic data available, the IPSS can be used for clinical decision-making.

[Prognostic value of noninvasive coronary plaque burden quantification in patients with risk factors].

Non-invasive quantitative indices of atherosclerosis are promising new parameters for an improved prognostic stratification of patients with risk factors that aim at individualized risk factor assessment and modification. In a recently published ACC/AHA consensus document, further data on the diagnostic and prognostic value of coronary calcified plaque quantification were strongly encouraged prior to its use in the general population. In this present work we summarize data published since, which contribute significantly to the prognostic value of fast CT-based noninvasive coronary calcified plaque quantification. It is a measure of atherosclerostic disease activity and is hence an index for the likelihood of future cardiovascular events. Current data indicate that noninvasive quantification of coronary atherosclerosis has incremental prognostic value beyond conventional single risk factor assessment. However, it is not clear yet whether it has a significant value beyond quantitative combined risk assessment using complex risk prediction models such as Framingham charts. Results from ongoing prospective trials such as the MESA study in the US and the Heinz Nixdorf Recall study in Germany will clarify some of the pending issues. In addition, it is still unclear, at what stage of the disease process, which of the available imaging tools will provide optimal diagnostic and prognostic value for the individual patient.

[Is there a prognostic indication for PTCA?].

Coronary angioplasty is classically indicated to remove a high grade stenosis of a major coronary vessel supplying a large myocardial territory in a symptomatic patient with proven myocardial ischemia. The coronary anatomy has to be suitable for PTCA to ensure a high success rate for the procedure. PTCA is performed to remove symptoms and myocardial ischemia to improve the prognosis of the patient. In contrast to this, the term "prognostic indication" describes an interventional approach to an angiographically documented high grade stenosis in an asymptomatic patient without proven myocardial ischemia thereby hoping to improve the prognosis of this patient. It has to be expected, that up to 20% of all patients treated by balloon angioplasty and 10% of all stented patients are treated with respect to a "prognostic indication". Until now, there are no statistically significant large-scale studies supporting a benefit of an interventional therapy performed with a "prognostic indication" in asymptomatic patients without ischemia. Nevertheless, some certain subgroups of patients may be candidates for a "prognostic indication" to angioplasty compared to the results of medical therapy. In patients treated interventionally for a "prognostic indication" the acute and long-term individual risk of the underlying coronary disease must be carefully weighted against the risk of the interventional procedure.

Prognostic importance of isolated peritumoral lymphangiosis carcinomatosa in lymph-node-negative colorectal carcinoma.

BACKGROUND: The prognostic value of microinvasion of lymph vessels and lymph nodes has become increasingly important; there is a wide range in prognosis of patients with nodal-negative tumor stages after curative resection for colorectal cancer. AIM: Detection of the prognostic importance of isolated lymph-vessel invasion as a possible precursor of lymph-node metastasis in patients with nodal-negative tumor stages. PATIENTS/METHODS: Retrospective analysis of 894 patients with R0-resected colorectal cancer, uni- and multivariate analysis of tumorbiologic prognostic factors, immunohistochemical proof of tumor cells in negative lymph nodes (pN0) using the epithelial marker HEA-125 (human epithelial antigen). RESULTS: The incidence of lymph-vessel invasion (L) was 37.7% in total. A pN0,L1 status was found in 144 patients (16.1% of all analyzed patients). Comparing patients with pN0,L1 status to those with pN+,L0 status showed that both groups have similar rates of overall survival and tumor relapse. Lymph-node status, lymph-vessel invasion, depth of tumor infiltration (pT) stage, and age were detected as independent prognostic factors by multivariate analysis. After reanalysis of 54 cases primarily classified as 18.5% pN0,L1, microinvasion in lymph nodes was detected by immunohistochemistry. We found a higher rate of tumor relapse (approximately 20%) for those patients. In regard to the overall survival rate, however, there was no difference when compared to patients without immunohistochemical proof of microinvasion. CONCLUSION: Isolated lymph-vessel invasion in nodal-negative tumor stages and a lymph-node-positive tumor status have equivalent prognostic importance in colorectal cancer.

Relationship and prognostic significance of phospho-(serine 166)-murine double minute 2 and Akt activation in node-negative breast cancer with regard to p53 expression.

The Akt signalling pathway plays a central role in tumourigenesis. Activation of Akt is related to a more aggressive phenotype in various human cancers, including breast cancer. Its activation contributes to cancer progression via pleiotropic effects, including suppression of apoptosis and modulation of cell cycle regulation. Murine double minute 2 (MDM2) is an oncoprotein that inhibits the function of p53 tumour suppressor protein. Cell culture studies show that Akt-related phosphorylation of MDM2 at serine 166 allows MDM2 to gain nuclear entry and fulfil its p53 regulating function. This study was designed to analyse the relationship of phospho-MDM2 (pMDM2) expression with Akt activation to determine a possible prognostic relevance of pMDM2 in node-negative breast cancer with respect to Akt activation and p53 status. pMDM2, phospho-Akt (pAkt) and p53 protein expression status were analysed immunohistochemically in 121 paraffin-embedded breast cancer cases. Expression of pMDM2 correlated with Akt activation (P<0.001). Univariate analysis identified pMDM2 as a prognostic factor (P=0.0458) in node-negative breast cancers. The unfavourable prognostic significance was even more pronounced in tumours with a pMDM2(+)/pAkt(+) immunophenotype (P=0.0205). Stratification into a p53-negative subgroup further strengthened the adverse prognostic influence. These data confirm that MDM2 phosphorylation at serine 166 is mediated by Akt kinase. Besides the prognostic impact of pMDM2, our findings suggest that Akt-mediated modulation of the MDM2/p53 complex contributes to increased tumour aggressiveness especially in p53-negative breast cancers. However, due to the relatively small number of patients in this cohort, the results obtained need to be confirmed by larger cohorts.

Activity of extracranial metastases as a prognostic factor influencing survival after radiosurgery of brain metastases.

Information about prognostic factors influencing survival have been only occasionally reported in studies on the use of radiosurgery in the treatment of patients with brain metastasis. To answer the question of whether activity of extracranial metastases is an independent prognostic factor influencing survival in radiosurgery of brain metastases, a review of the literature was performed. Fourteen studies were identified in the English language literature that dealt with this topic. Only three studies showed borderline insignificance of the influence of activity of extracranial metastases when analysed by univariate methods. When multivariate analysis was used to test for the independent influence of this factor on survival, of nine studies that used that statistical approach eight showed that it is an independent prognosticator influencing survival, most often being the strongest one. This review of literature supports the view that the "activity of extracranial metastases" is an independent prognostic factor influencing survival of these patients as documented in published reports. However, prospective randomised trials are necessary to definitely establish the independent influence of this prognostic factor.

A prospective study on the prognostic significance of urokinase-type plasminogen activator levels in breast cancer tissue.

Urokinase-type plasminogen activator (u-PA), which cleaves plasminogen to yield plasmin, is a serine protease of fibrinolysis and is presumed to play a key role in extracellular proteolysis and facilitate the migration of cancer cells. This study was conducted prospectively to evaluate the prognostic significance of u-PA antigen level in breast cancer tissues. u-PA concentrations in the cytosol of 226 breast cancer tissues were determined prospectively by enzyme-linked immunosorbent assay using cytosol fractions prepared for steroid hormone assay. The median follow-up period of the patients was 60 months. Various prognostic factors were evaluated by univariate analysis or multivariate analysis using the Cox proportional-hazards method. Patients with primary breast cancer containing high levels of u-PA had a significantly shorter disease-free survival than patients with low levels of u-PA antigens. In multivariate analysis, a high level of u-PA was an independent risk factor for disease-free survival, being independent of age, axillary node status, and estrogen receptor status. Among the major prognostic factors, a high u-PA antigen level, lymph node involvement, and a positive estrogen receptor status were the most important for predicting relapse-free survival (P = 0.044, P < 0.0001, P = 0.0039). This first prospective study confirmed the prognostic significance of the u-PA antigen level in association with other major prognostic factors. The results of our present study suggest that u-PA in breast cancer tissue might be involved in breast cancer invasion and metastasis.

The significance of perineural invasion as a prognostic factor in patients with gastric carcinoma.

PURPOSE: Few studies have investigated the prognostic significance of perineural invasion (PNI) in gastric cancer. Therefore, we examined the association between PNI and clinicopathological factors and the effect of PNI on overall survival in patients with gastric carcinoma. METHODS: Paraffin sections of surgical specimens from 354 patients who underwent gastric resection were stained with hematoxylin and eosin. PNI was assessed histologically as positive when cancer cells were seen in the perineurium or neural fascicles. Survival analysis was done in 219 patients with T(2,3,4) tumors who underwent potentially curative resection. Data were collected prospectively. RESULTS: PNI was positive in 211 of the 354 patients (59.6%). The ratio of undifferentiated tumors, tumors with vascular invasion, and lymph node metastasis was significantly higher in the PNI-positive patients than in the PNI-negative patients ( P < 0.0001 for all three associations). As the depth of mural invasion increased, so did PNI positivity ( P < 0.0001). The overall survival of the PNI-positive patients was significantly worse than that of the PNI-negative patients in the univariate analysis ( P = 0.0009). However, PNI had no independent prognostic significance in the multivariate Cox proportional hazards model analysis. When the patients were separated into subgroups, PNI had prognostic value in patients with T(3) tumors ( P = 0.036) and no lymph node metastasis ( P = 0.005) in the univariate analysis, but no prognostic significance in the multivariate analysis. CONCLUSIONS: Although the incidence of PNI is high in gastric carcinoma and increases with the progression of disease, it does not provide any additional information to the classical prognostic parameters.

The prognostic value of age, gender, pregnancy and endocrine factors in multiple sclerosis.

The evolution of multiple sclerosis at the time of diagnosis remains unpredictable since a reliable prognostic marker is not yet available. Nevertheless, a series of useful prognostic indicators have been singled out from epidemiological studies. Young age at onset, female gender, relapsing/remitting course, and sensitive or visual disturbances as initial symptoms are considered favourable prognostic factors. Conversely, late age at onset, male gender, progressive course, and pyramidal or cerebellar symptoms at the first episode predict an unfavourable evolution. Another prognostic indicator has been recognized in pregnancy: although the overall effect of pregnancy on short-term MS course is neutral, in the long-term it seems to protect from disease progression. Most prognostic indicators seem to act through the neuro-endocrine-immune network, modulating the immune response in the context of the Th1/Th2 paradigm.

Identification and validation of prognostic genes associated with mitochondrial nuclear genes in gastric cancer.

Mitochondrial-related nuclear genes (MNGs) have shown great importance in cancer diagnosis and prognosis, but their role in gastric cancer (GC) remains unclear. GC-related transcriptome data from the gene expression omnibus and cancer genome atlas databases were analyzed to identify differentially expressed MNGs. A prognostic risk model was constructed through univariate Cox and least absolute shrinkage and selection operator regression, validated by Kaplan-Meier (K-M) survival curve and receiver operating characteristic curve. This was followed by immune infiltration analysis, independent prognostic analysis, functional enrichment analysis, drug sensitivity analysis, drug prediction, molecular docking and construction of regulatory networks. Three prognostic genes (ATP8A2, COX15 and TARS2) were identified. The expression of TARS2 and COX15 was positively correlated with CNV, while ATP8A2 was unaffected. The risk model and nomogram, integrating risk score and clinicopathological factors, exhibited excellent predictive performance. A significant correlation was observed between prognostic genes and differential immune cells, such as T cells, B cells, and NK cells. BMS-754807, Gefitinib, JQ1, Lapatinib, and Sapitinib exhibited significant differences in sensitivity between the high-risk group and the low-risk group. The results of molecular docking showed TP8A2 has stable binding ability with cytosine, COX15 with indomethacin, and TARS2 with bisacodyl. RT-qPCR revealed downregulation of ATP8A2 and upregulation of COX15 and TARS2 in GC samples. MNGs, including ATP8A2, COX15, and TARS2, demonstrated significant associations with immune infiltration, CNV, and prognostic outcomes of GC.

Lysozyme expression by breast carcinomas, correlation with clinicopathologic parameters, and prognostic significance.

BACKGROUND: Here we evaluate the expression and prognostic value of lysozyme, a milk protein that is also synthesized by a significant percentage of breast carcinomas, in women with breast cancer. METHODS: Lysozyme expression was examined by immunohistochemical methods in a series of 177 breast cancer tissue sections. Staining was quantified by using the HSCORE system, which considers both the intensity and the percentage of cells staining at each intensity. The prognostic value of lysozyme was retrospectively evaluated by multivariate analysis that took into account conventional prognostic factors. RESULTS: A total of 126 of 177 carcinomas (69.4%) stained positive for this protein, but there were clear differences among them with regard to the intensity and percentage of stained cells. Lysozyme values were higher in well-differentiated and moderately differentiated tumors than in poorly differentiated tumors (P < .05). Similarly, lysozyme levels were higher in small and node-negative tumors than in large and node-positive tumors (P < .05). Moreover, results indicated that low lysozyme content predicted shorter relapse-free survival and overall survival (P < .005). Separate Cox multivariate analysis in subgroups of patients as defined by node status showed that lysozyme expression was an independent prognostic factor able to predict both relapse-free survival and overall survival in node-negative patients (P < .05). CONCLUSIONS: Tumoral expression of lysozyme is associated with lesions of favorable evolution in breast cancer. This milk protein may be a new prognostic factor in patients with breast cancer.

High prognostic significance of residual disease after neoadjuvant chemotherapy: a retrospective study in 710 patients with operable breast cancer.

Prognostic factors are used to help clinical decision-making in selecting the appropriate treatment for individual patients. The purpose of this retrospective study was to identify one or more factors associated with overall survival (OS) and disease-free survival (DFS), in 710 patients with operable breast cancer, subjected to neoadjuvant chemotherapy followed by surgery, radiotherapy and adjuvant treatments. At a median follow-up of 7.6 years, univariate analysis showed that pathological complete response (pCR) was significantly related to survival (p < 0.003), as well as accepted prognostic factors, as SBR and MSBR grades, hormonal receptors or node involvement at surgery, who remained significant in our study (p < 0.001). The revised Nottingham prognostic index (NPI) and related indices (BGI, MNPI and MBGI) were also significantly associated to survival (p < 0.003). In multivariate analysis, node involvement and MSBR grade remained prognostic factors for OS and DFS (p < 0.0003 and p < 0.02, respectively). The MNPI and pCR were significantly related with OS (p = 0.04) and pts with hormonal receptor-positive tumours had a better DFS than others (p = 0.004). Among all clinical and pathological parameters, axillary dissection after neoadjuvant chemotherapy is still important to determine node involvement, a major prognostic factor. Moreover, MSBR grade seemed to be more accurate and predictive of long-term outcome than the standard SBR grade. It is concluded that, outside any other 'biological' factor, residual disease in breast and nodes must be strongly considered after an induction chemotherapy so as to choose adjuvant treatment for the individual patient.

Prognostic factors for patients with liver metastases from breast cancer.

BACKGROUND: The prognosis of patients with liver metastases from breast cancer is commonly poor. After initial diagnosis of hepatic metastases, a median survival time of 1-20 months can be expected. The definition of prognostic factors for such patients may influence therapeutic decisions. In particular, the characterization of patients who can expect long-term survival could assist in optimizing treatment. METHODS: We retrospectively studied n = 350 patients with liver metastases from breast cancer. All patients were stratified following their survival after occurrence of liver metastases. Kaplan-Meier studies were performed, as well as univariate and multivariate analyses of several clinical, histopathological and therapeutic factors. RESULTS: Median survival time was 14 months. N = 66 (18.9%) patients survived longer than 36 months after the primary diagnosis. Multivariate analysis showed prognostic relevance for the time interval between the primary diagnosis of breast cancer and the initial diagnosis of hepatic metastases (p < 0.05). Furthermore, prognostic relevance was found for the pattern of metastasization (p < 0.05) and for signs of hepatic dysfunction (ascites, jaundice, p < 0.005). Univariate analysis showed a prognostic benefit for patients with an expression of Ki-67 < 20%, p53 < 50% and a positive hormonal receptor status. Patients who received a regional therapy survived on average longer than patients who were only treated systemically (33 versus 11 months, p < 0.001). CONCLUSIONS: Consideration of prognostic implications of the described parameters may help to find the most appropriate treatment for patients with liver metastases from breast cancer. The possibility of local therapeutic interventions should be considered in a defined subgroup.

Prognostic significance of changes in CA 15-3 serum levels during chemotherapy in metastatic breast cancer patients.

Tumor response to first-line chemotherapy in advanced breast cancer offers prognostic information and may be used as a surrogate marker for evaluating treatment efficacy. With this study we wanted to determine whether changes in circulating serum CA 15-3 levels during chemotherapy provided additional information for prognostic prediction. Serum CA 15-3 was measured at baseline and after 3 and 6 months during anthracycline-based first-line chemotherapy in 526 patients with advanced breast cancer prospectively enrolled in five phase II-III trials. Changes in marker levels were correlated with disease response, time to progression and overall survival. In all, 336 patients attained a disease response. A significant relationship was found between disease response and CA 15-3 variations, although many individual discrepancies were also observed. At the 6-month time point, the median time to progression was 15.3 months in patients with normal marker levels throughout the study, 11.7 months in those with a CA15-3 reduction >25%, 9.6 months in those with elevated baseline CA 15-3 levels which did not change during therapy and 8.6 months in those with increased marker levels (p < 0.001). The median survival was 42.3, 29.7, 28.5, and 24.8 months, respectively (p < 0.002). The prognostic role of changes in CA 15-3 levels was maintained in the patient subset attaining disease response or stabilization to treatment (p < 0.001) and after adjusting for clinical response and major prognostic parameters in the multivariate analysis (p < 0.001). In conclusion, monitoring serum CA 15-3 levels during first-line chemotherapy in advanced breast cancer patients provides prognostic information independently from tumor response.

Prognostic Value of Circulating Tumor DNA-Based Minimal Residual Disease for Recurrence-Free Survival in Resectable Gastric Cancer: A Systematic Review and Meta-Analysis with Serial Monitoring Analysis.

BACKGROUND: Circulating tumor DNA (ctDNA)-based minimal residual disease (MRD) is an emerging biomarker, but its utility in resectable gastric cancer remains incompletely characterized. METHODS: We conducted a systematic review and meta-analysis of eight studies (520 patients) to evaluate the prognostic value of ctDNA-based MRD for recurrence-free survival (RFS) and overall survival (OS) in resectable gastric cancer. RESULTS: In localized resectable gastric cancer (Stage I-III), the setting in which postoperative ctDNA most coherently represents true molecular residual disease after curative-intent surgery, postoperative ctDNA positivity was associated with diminished recurrence-free survival (RFS: HR 12.26, 95% CI 3.30-45.52) and overall survival (OS: HR 8.57, 95% CI 3.06-23.98). The test for subgroup differences between localized and mixed-stage cohorts was not statistically significant (P = 0.57), and the numerically higher HR in the localized subgroup should therefore not be interpreted as evidence of a quantitatively stronger prognostic effect. Postoperative ctDNA detection demonstrated substantially stronger prognostic value (overall RFS: HR 10.00, 95% CI 4.53-22.10) compared to preoperative assessment (HR 2.17, 95% CI 1.10-4.28). Both tumor-informed and tumor-agnostic strategies effectively stratified high-risk patients. However, these effect sizes should be interpreted cautiously given the small number of studies and substantial heterogeneity (I2 = 65-72%). Results from mixed-stage cohorts including Stage IV disease are supportive but should not be considered equivalent to localized-disease findings, as ctDNA in metastatic disease reflects persistent systemic burden rather than minimal residual disease in the postoperative sense. CONCLUSIONS: Postoperative ctDNA-based MRD shows a consistent adverse prognostic association in resectable gastric cancer, with localized disease (Stage I-III) representing the most biologically and clinically coherent setting for interpretation. However, the large pooled hazard ratios (HR 10.00-12.26) should be interpreted as a directionally consistent signal rather than precise quantitative estimates, given the small number of studies, wide confidence intervals, and substantial heterogeneity (I2 = 65-73%). This heterogeneity is largely driven by substantial variation in postoperative sampling timing (4 days to 16 weeks) and ctDNA assay characteristics (platform, sensitivity, coverage, variant filtering, and positivity thresholds), which require standardization in future studies. While ctDNA is prognostically valuable, its clinical utility remains unestablished. Prospective randomized trials are needed to determine whether ctDNA-guided strategies improve patient outcomes before routine clinical implementation can be recommended.

Utilizing prognostic and predictive factors in breast cancer.

In order to make optimal treatment recommendations for patients with early-stage breast cancer, it is essential to accurately determine the patient's underlying risk of disease recurrence and choose a therapy to which the individual is most likely to respond. Lymph node status, tumor size, histopathologic features including tumor type and grade, and hormone receptor status are well-accepted prognostic factors related to breast cancer. In addition, hormone receptor status is a very strong predictor of response to hormonal therapy. However, our currently accepted prognostic and predictive factors fall short and there is a critical need to more accurately identify those most likely to require or benefit from particular therapies. Attention has therefore focused on the determination of novel prognostic and predictive factors. The most promising new factor is the level of urokinase plasminogen activator and its inhibitor plasminogen activator inhibitor. Other putative factors include proliferative rate, the presence of lymphatic or vascular invasion, human epidermal growth factor receptor 2 (HER-2/neu or erbB-2) positivity, the presence of micrometastases in lymph nodes or bone marrow, and gene expression profile by microarray analysis, and by RNA-based methodology. Data regarding potential new prognostic factors are constantly emerging. These studies are frequently challenging to interpret as they are often retrospective, based on relatively small numbers of patients, include a mix of treated and untreated women, and often do not control for other known prognostic factors. Therefore, new data must be interpreted with caution.

Designing clinical trials for kidney cancer based on newly developed prognostic and predictive tools.

Several advances have been made in our understanding of the molecular aberrations in renal cell carcinoma that have led to the identification of novel prognostic and predictive biomarkers. At the same time, several novel agents targeting these molecular aberrations have shown promising efficacy in the therapy of advanced renal cancer. As these agents enter more advanced-stage clinical trials, efforts must be made to integrate exploration of these novel prognostic and predictive markers into clinical trial design. These elements then can be combined with more traditional prognostic features to form more robust prognostic models. Finally, predictive markers and prognostic models should be validated prospectively, either as part of clinical trials designed specifically for that purpose or as part of large phase-3 trials. Once validated, these features can be used to best inform prognosis and guide therapy based on individual patient characteristics.

Comprehensive investigation identifies CPSF3 as a novel prognostic and oncogenic biomarker in bladder cancer.

BACKGROUND: Bladder cancer (BC) remains a prevalent malignancy worldwide, with rising incidence rates each year. Despite progress in therapeutic strategies, many patients suffer recurrence or progression, emphasizing the urgent need for novel prognostic biomarkers and therapeutic targets. This research evaluated the prognostic relevance and functional role of Cleavage and Polyadenylation Specificity Factor 3 (CPSF3) in BC. METHODS: We analyzed CPSF3 expression using The Cancer Genome Atlas data and immunohistochemistry on a cohort of 203 BC patients. A nomogram incorporating CPSF3 expression was developed based on CPSF3 expression for prediction of overall survival and disease-free survival. Immune infiltration analyses and transcriptome sequencing were performed to explore underlying biological mechanisms. In vitro and in vivo experiments were utilized to examine the results of CPSF3 silencing on bladder cancer cell growth, colony-forming ability and cell cycle transitions. RESULTS: Elevated CPSF3 expression was significantly linked to unfavorable overall survival and disease-free survival both in TCGA datasets and our cohort. The CPSF3-based nomogram outperformed conventional prognostic models. CPSF3 expression was associated with tumor-infiltrating immune cells and immune checkpoint markers. Enrichment analysis revealed CPSF3 enrichment in cell cycle-related pathways. Suppression of CPSF3 expression led to marked reductions in cell proliferation, colony formation, tumor growth in animal models and inhibited G1 to S phase progression. CONCLUSION: CPSF3 is a promising prognostic biomarker for BC and may play a crucial role in BC progression. Incorporating CPSF3 into clinical prognostic models may enhance prediction of patient outcomes. CPSF3 may represent a promising therapeutic target for BC management.
