Background: Complete rectal prolapse (RP) is a debilitating pelvic floor disorder often accompanied by obstructed defecation syndrome (ODS), fecal incontinence, and LARS-like bowel dysfunction. Laparoscopic resection rectopexy (LRR) is an established abdominal approach; however, functional outcomes after LRR with transanal specimen extraction (LRR-TSE) are incompletely defined. Aim: To evaluate short- and long-term functional outcomes—ODS, Wexner incontinence score (WIS), and LARS—in patients undergoing LRR-TSE. Methods: This single-center cohort included 53 consecutive patients who underwent LRR-TSE between January 2013 and December 2019. Variables were prospectively recorded and analyzed retrospectively. ODS, WIS, and LARS scores were assessed preoperatively and at 3, 6, and 12 months. Longitudinal changes were analyzed using repeated-measures ANOVA with Greenhouse–Geisser correction, polynomial contrasts when appropriate, and Bonferroni-adjusted pairwise comparisons. Results: ODS improved significantly over time (p < 0.001), decreasing from 12.8 ± 3.2 preoperatively to 2.4 ± 2.1, 4.2 ± 2.2, and 5.2 ± 2.9 at 3, 6, and 12 months, respectively. LARS scores declined from 18.0 ± 12.7 at 3 months to 8.8 ± 6.8 at 6 months and 3.5 ± 4.2 at 12 months (p < 0.001). WIS showed a transient increase at 3 months (8.1 ± 5.2), followed by improvement at 6 and 12 months (3.2 ± 3.7 and 2.4 ± 3.0; p < 0.001). Sex and body mass index did not affect functional trajectories (p > 0.05), whereas patients aged ≥50 years had higher postoperative LARS and WIS scores (p < 0.05). Complications occurred in 5 patients (9.43%), including one anastomotic leak with a mortality rate of 1.85%. Full-thickness recurrence occurred in 2 patients (3.77%), and 3 developed mucosal prolapse managed with Delorme’s procedure. Conclusions: LRR-TSE is a safe and feasible minimally invasive technique that improves constipation, continence, and LARS-related bowel dysfunction. Early postoperative impairment may overestimate long-term functional severity, highlighting the need for follow-up beyond 12 months. Full article

Background/Objectives: The growing population of women aged ≥ 80 years poses a new challenge for urogynecology. Advanced age, comorbidities, and polypharmacy raise concerns regarding the safety of procedures in the management of pelvic floor disorders (PFDs) such as pelvic organ prolapse (POP), stress urinary incontinence (SUI), and overactive bladder (OAB). Individualized, frailty-based assessment is essential in this group. The aim of the study was to evaluate the safety profile of urogynecological surgical procedures among women aged ≥ 80 years at a single tertiary center. Methods: In a retrospective observational single-center study, we analyzed the medical documentation of 774 hospitalizations of women aged ≥ 80 years admitted between 2014 and 2023. The analysis included indications, comorbidities, treatment types, anesthesia, and complications. Comorbidity and surgical risk were evaluated using the Charlson Comorbidity Index (CCI) and Clavien–Dindo classification. Results: A total of 720 admissions with complete medical records were analyzed, of which 65% were for urogynecological conditions. In this group, the mean age was 83.0 years and mean BMI was 27.2 kg/m². Most patients (92.9%) had comorbidities, mainly hypertension (84.2%) and diabetes (21.1%). POP was the leading indication (52%), followed by SUI (35%) and OAB (27%). Surgical management was performed in 95% of POP cases, predominantly via vaginal native tissue repair (80%), especially LeFort colpocleisis (20%). The transobturator sling (TOT) was the most frequent SUI surgery. Intraoperative complications occurred in 1.5% of cases and postoperative ones were mainly minor (Clavien–Dindo I–II). No procedure-related deaths were recorded. Conclusions: In this cohort, surgical treatment of urogynecological problems in women ≥80 years was associated with a low rate of major complications, suggesting that it can be safely offered to elderly patients. Careful preoperative assessment based on frailty and comorbidity rather than chronological age remains essential. Full article

Background: Urinary incontinence (UI) is common in women and negatively affects quality of life. Although pelvic floor muscle training (PFMT) is effective, most studies have focused on isolated muscle contractions. Less is known about multimodal programs integrating posture, breathing, and intra-abdominal pressure management. This study examined how urinary loss (UL) and moderate physical activity (MPA), measured objectively, relate to perceived pelvic floor disorders after a five-week multimodal intervention. Methods: Twenty women (40–70 years) with UI participated in three weekly 60 min sessions for five weeks. Outcomes were assessed before and after the intervention: UL using the pad test, physical activity with a wrist-worn accelerometer, and pelvic floor disorders with the Pelvic Floor Distress Inventory (PFDI-20). Paired t-tests or Wilcoxon tests and regression models were used to analyze changes and associations between variables. Results: UL significantly decreased after treatment (p < 0.001) as did total PFDI-20 (p = 0.007). Before treatment, PFDI-20 was mainly predicted by MPA (β = −0.537, p = 0.013). After treatment, UL became the strongest predictor of PFDI-20 (β = 0.587, p = 0.008) while Δ analyses confirmed that changes in both UL (β = 0.444, p = 0.026) and MPA (β = −0.461, p = 0.021) predicted improvements in perceived pelvic floor disorders. Conclusions: A five-week multimodal program reduced UL and improved perceived pelvic floor disorders. After treatment, symptoms were more strongly related to UL than to MPA. This study suggests that a multimodal exercise approach may represent a feasible and potentially effective option for improving both objectively measured urinary loss and perceived pelvic floor symptoms.

Background and Objectives: Pelvic organ prolapse (POP) is a prevalent pelvic floor disorder affecting a large proportion of parous and aging women worldwide. While surgical intervention is generally reserved for advanced prolapse, conservative approaches remain essential for the management of early-stage disease. Flat magnetic stimulation (FMS), a novel non-invasive modality, has shown promising results in pelvic floor rehabilitation for urinary incontinence, but its role in prolapse treatment remains insufficiently investigated. This study aimed to evaluate anatomical and patient-reported outcomes in women with mild POP undergoing FMS therapy. Materials and Methods: This retrospective observational study included 87 women with stage ≤ 2 POP, classified according to the Pelvic Organ Prolapse Quantification (POP-Q) system. Participants underwent eight FMS sessions, each lasting 25 min, over four weeks using the Dr. Arnold device (DEKA, Calenzano, Italy). Pre- and post-treatment evaluations included standardized POP-Q measurements and the Patient Global Impression of Improvement (PGI-I) questionnaire. Statistical analyses were performed using paired t-tests, with significance set at p < 0.05. Results: Statistically significant improvements were observed in the anterior vaginal compartment, with mean Aa values improving from −0.3 ± 1.2 to −0.7 ± 1.3 (mean difference −0.4 cm; 95% CI −0.8 to −0.03; p = 0.03; Cohen’s d = 0.31) and mean Ba values from −0.3 ± 1.3 to −0.7 ± 1.3 (mean difference −0.4 cm; 95% CI −0.8 to −0.02; p = 0.04; Cohen’s d = 0.30). No significant changes were found at other POP-Q landmarks. According to PGI-I results, 90.8% of participants reported symptom improvements, and 37.9% described their condition as “very much improved” or “much improved.” No adverse events occurred, and treatment compliance was 100%. Conclusions: FMS seems to be a safe, well-tolerated, and potentially effective conservative therapy strategy for mild POP, offering both objective anatomical benefits and high subjective satisfaction. Further randomized controlled trials with longer follow-up are required to validate these findings and clarify the long-term role of FMS in the management of pelvic floor dysfunction. Full article

Background and Objectives: Pelvic floor disorders are highly prevalent among women globally and can severely compromise daily functioning and well-being. Emerging energy-based modalities have reshaped conservative management strategies, by allowing individualized therapeutic approaches. The aim of this study was to evaluate the utility of customized energy-based applications, via an innovative multimodal EVA/DAFNE device that incorporates multimodal energy-based synergistic technologies for the treatment of pelvic floor dysfunction. Materials and Methods: Patients with PFDs (pelvic organ prolapse, all types of urinary incontinence, bladder voiding dysfunction, and dyspareunia) who selected conservative treatments were prospectively enrolled. Baseline and after-treatment quality of life was assessed using the following validated tools: Urinary Distress Inventory-6 (UDI-6), Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6), Female Sexual Function Index-6 (FSFI-6), Marinoff Scale, 0-100 VAS, and Vaginal Health Index. Overall improvement was measured through the Patient Global Impression of Improvement (PGI-I). Three to five sessions of treatment tailored according to the patient’s symptoms and clinical findings were delivered. Data were analyzed using standard statistical methods. Results: Twenty-six women with PFD who desired energy-based conservative treatment were recruited. Mean age was 48.6 ± 16.7 years. Indications for treatment were dyspareunia (n = 10; 38.5%), stress urinary incontinence (n = 9; 34.6%), mild pelvic organ prolapse (n = 6; 23.1%), genitourinary syndrome of menopause (n = 5; 19.2%), voiding dysfunction (n = 4; 15.4%), and overactive bladder syndrome (n = 2; 7.7%). Mean number of treatments was four. Baseline and after-treatment quality-of-life scores differed significantly. According to PGI-I scores 88.5% of patients considered themselves improved. Conclusions: Our study provides pilot estimates as to the safety and efficacy of a multimodal integrated treatment protocol for the treatment of PFD. Integrating multimodal energy-based conservative therapy into tailored treatment protocols can prove efficient and useful. Full article

Introduction: Multiple sclerosis (MS) is a chronic neurodegenerative disease that entails high costs, progressive disability, and reduced quality of life (QoL). Telerehabilitation (TR), supported by new technologies, is emerging as an alternative or complement to in-person rehabilitation, potentially lowering socioeconomic impact and improving QoL. Aim: The objective of this study was to evaluate the effect of TR on the QoL of people with MS compared with in-person rehabilitation or no intervention. Materials and methods: A systematic review of randomized clinical trials was conducted (March–May 2025) following PRISMA guidelines. Searches were run in the PubMed-Medline, EMBASE, PEDro, Web of Science, and Dialnet databases. Methodological quality was assessed with the CASP scale, risk of bias with the Risk of Bias 2 tool, and evidence level and grade of recommendation with the Oxford Classification. The protocol was registered in PROSPERO (CRD420251110353). Results: Of the 151 articles initially found, 12 RCTs (598 total patients) met the inclusion criteria. Interventions included (a) four studies employing video-controlled exercise (one involving Pilates to improve fitness, another involving exercise to improve fatigue and general health, and two using exercises focused on the pelvic floor muscles); (b) three studies using a monitoring app to improve manual dexterity, symptom control, and increased physical activity; (c) two studies implementing an augmented reality system to treat cognitive deficits and sexual disorders, respectively; (d) one platform with a virtual reality headset for motor and cognitive training; (e) one study focusing on video-controlled motor imagery, along with the use of a pain management app; (f) a final study addressing cognitive training and pain reduction. Studies used eight different scales to assess QoL, finding similar improvements between groups in eight of the trials and statistically significant improvements in favor of TR in four. The included trials were of good methodological quality, with a moderate-to-low risk of bias and good levels of evidence and grades of recommendation. Conclusions: TR was more effective in improving the QoL of people with MS than no intervention, was as effective as in-person treatment in patients with EDSS ≤ 6, and appeared to be more effective than in-person intervention in patients with EDSS between 5.5 and 7.5 in terms of QoL. It may also eliminate some common barriers to accessing such treatments. Full article

Background/Objectives: Pelvic floor disorders affect up to 30% of adult females in the United States. Misdiagnosis occurs in nearly 45% to 90% of cases. Standardized pelvic anatomical measurements could improve diagnostic accuracy and treatment planning. We aimed to evaluate pelvic anatomical variations using magnetic resonance imaging (MRI). Methods: We analyzed MRI pelvic measurements from 250 women aged 20–90 years. Exclusion criteria included prior pelvic surgery (except hysterectomy), pelvic cancer, and use of alternative imaging modalities. Key measurements included anterior vaginal wall thickness (AVWT), bladder wall thickness (BWT), vaginal epithelium to bladder urothelium (VWBU), urethral length (UL), and inter-ureteral distances. A comprehensive statistical analysis was performed, including corrections for multiple comparisons. Results: While several anatomical measurements were correlated, a comprehensive analysis was performed to identify markers for clinical diagnoses. After applying Bonferroni correction for multiple comparisons, we found no statistically significant association between any of the measured anatomical parameters and a diagnosis of incontinence. Notably, an uncorrected difference in Bladder Wall Thickness (BWT) (p = 0.041) did not hold up to rigorous testing. To further assess its clinical utility, a Receiver Operating Characteristic (ROC) curve analysis for BWT as a predictor of incontinence yielded an aArea Under the Curve (AUC) of 0.19, indicating poor predictive validity. Conclusions: In this cohort, static anatomical measurements derived from MRI, including BWT, do not appear to be reliable markers for incontinence. Our findings suggest that the pathophysiology of this disorder is likely more dependent on functional or dynamic factors rather than simple static anatomical variations. Future research should focus on standardizing dynamic imaging parameters to better assess pelvic floor function. Full article

Acute transverse myelitis (ATM) is a rare, immune-mediated disorder of the spinal cord characterized by sensory, motor, and autonomic dysfunction. Although the human papillomavirus (HPV) vaccine is widely regarded as safe, isolated reports have suggested a potential temporal association with autoimmune neurological events, including ATM. We present a case of a 21-year-old woman who developed ATM two weeks following administration of the first dose of the HPV vaccine (Cervarix). The clinical presentation included rapid-onset paraparesis, sensory deficits, and sphincter dysfunction. An MRI revealed a T2-hyperintense lesion at the Th10–Th12 level. A cerebrospinal fluid analysis showed elevated protein levels. The patient underwent corticosteroid therapy, plasmapheresis, and IVIG, followed by a comprehensive, individualized rehabilitation program. This included balance and stability training, Redcord-based neuromuscular activation, electrostimulation, and pelvic floor therapy. Although no causal link between HPV vaccination and ATM has been established, this case emphasizes the importance of considering post-vaccinal autoimmune phenomena. More importantly, it illustrates the critical role of early, targeted rehabilitation—particularly pelvic floor re-education and neuromodulation—in improving outcomes in patients with significant motor and autonomic deficits.

Ulcerative colitis is a chronic intestinal disorder that belongs to the category of inflammatory bowel diseases, and is usually characterized by the presence of bloody diarrhea and abdominal pain, due to an accelerated transit and intestinal sensibilization following inflammation of the colonic mucosa. However, the literature reports that ulcerative colitis may sometimes feature fecal stasis with constipation. This apparent paradox may be partially explained by the motor abnormalities of the large bowel following inflammation, damage to the enteric innervation, and the onset of parietal fibrosis over time. Moreover, some anorectal abnormalities such pelvic floor dyssynergia may explain the symptoms of constipation reported in subsets of patients. Since these abnormalities may be responsible for diagnostic delays and non- or partial responses to therapy, it is important to recognize them as early as possible to avoid incorrect clinical and therapeutic approaches to these patients.

Background/Objectives: Pelvic floor disorders (PFDs) have multifactorial etiology. This makes treatment challenging and often unsatisfactory. This project introduces robust data on risk factors for PFDs and explores opportunities for their prevention, focusing on previous gynecological surgical interventions. Methods: We conducted a retrospective analytical cohort study analyzing demographic and clinical data from 832 consecutive patients who underwent pelvic organ prolapse (POP) surgery at a teaching hospital affiliated with the University of Cologne between 2010 and 2019. Patient characteristics—including age, body mass index (BMI), parity, mode of delivery, and symptoms—were collected from medical records. Associations between patient factors and surgical history were assessed using Kendall’s Tau (KT) for correlations and relative risks (RRs) with 95% confidence intervals (CIs) to evaluate the impact of previous hysterectomies and pelvic surgeries on PFD. Results: First vaginal delivery and age were the strongest factors associated with PFD. BMI had a smaller impact, and multiple vaginal deliveries did not significantly influence apical (KT 0.037), posterior (KT 0.007), anterior midline (KT 0.015), or lateral defects (KT 0.015). Cesarean section was protective. Subtotal hysterectomy showed no significant association with PFD. Total hysterectomy was strongly associated with posterior defects (RR 4.750, 95% CI: 1.871–12.059) and anterior midline defects (RR 1.645, 95% CI: 0.654–4.139). Recurrent urinary infections were associated with abdominal colposuspension (RR 4.485, 95% CI: 1.12–18.03). Dyspareunia occurred more frequently after vaginal (RR 3.971, 95% CI: 0.78–20.14) and abdominal hysterectomy (RR 1.620, 95% CI: 0.32–8.15). Vaginal hysterectomy was linked to fecal incontinence (RR 5.559, 95% CI: 1.17–26.30), MUI (RR 2.156, 95% CI: 1.09–4.23), and UUI (RR 4.226, 95% CI: 1.82–6.85). Conclusions: The factors identified as influencing (PFD) offer a solid foundation for evidence-based patient counseling within our population. Our large dataset confirmed key risk factors, notably childbirth and advancing age. However, the influence of BMI on symptoms and anatomical defects appears to be less significant than previously assumed. Subtotal hysterectomy was not associated with new PFD in our cohort and may represent a viable option when hysterectomy is indicated, though further studies are needed to confirm this potential advantage.

Background/Objectives: Pelvic organ prolapse (POP) is a common condition that significantly impacts quality of life. Research has focused largely on older women, while experiences of younger women remain relatively underexplored despite challenges unique to this population. Informed by the biopsychosocial model of illness, this study aims to assess the symptom burden, treatment goals, and information needs of younger women complaining of prolapse by analyzing questionnaire responses from an existing electronic Personal Assessment Questionnaire—Pelvic Floor (ePAQ-PF) dataset. Methods: Mixed-methods content analysis was conducted using free-text data from an anonymized multi-site ePAQ-PF dataset of 5717 responses collected across eight UK NHS trusts (2018–2022). A quantitative, deductive approach was first used to identify younger women (≤50 years old) with self-reported prolapse. ePAQ-PF scores for younger women with prolapse were compared with those aged >50 years, using Mann–Whitney tests. Free-text response data were analyzed inductively to qualitatively explore younger women’s symptom burden, treatment goals, and information needs. Results: Of the 1473 women with prolapse identified, 399 were aged ≤50 years. ePAQ-PF scores of the younger cohort demonstrated significantly greater symptom severity and bother than those aged >50, particularly in bowel, prolapse, vaginal, body image, and sexual health domains (p < adjusted threshold). Qualitative analysis undertaken to understand women’s concerns and priorities produced five health-related themes (physical health; functionality; psychosocial and emotional wellbeing; reproductive and sexual health; and healthcare journeys) and a sixth intersecting theme representing information needs. Conclusions: The findings highlight the substantial symptom burden of younger women with prolapse, as well as treatment goals and information needs specific to this population. The development of age-specific resources is identified as a requirement to support this group. Full article

Pelvic organ prolapse (POP) is a common pelvic floor disorder with substantial impact on women’s quality of life, necessitating accurate and reproducible diagnostic methods. This study investigates the use of three-dimensional (3D) transperineal ultrasound, integrated with artificial intelligence (AI), to evaluate pelvic floor biomechanics and identify correlations between biometric parameters and prolapse severity. Thirty-seven female patients diagnosed with genital prolapse (mean age: 65.3 ± 10.6 years; mean BMI: 29.5 ± 3.8) were enrolled. All participants underwent standardized 3D transperineal ultrasound using the Mindray Smart Pelvic system, an AI-assisted imaging platform. Key biometric parameters—anteroposterior diameter, laterolateral diameter, and genital hiatus area—were measured under three functional states: rest, maximal Valsalva maneuver, and voluntary pelvic floor contraction. Additionally, two functional indices were derived: the distensibility index (ratio of Valsalva to rest) and the contractility index (ratio of contraction to rest), reflecting pelvic floor elasticity and muscular function, respectively. Statistical analysis included descriptive statistics and univariate correlation analysis using Pelvic Organ Prolapse Quantification (POP-Q) system scores. Results revealed a significant correlation between laterolateral diameter and prolapse severity across multiple compartments and functional states. In apical prolapse, the laterolateral diameter measured at rest and during both Valsalva and contraction showed positive correlations with POP-Q point C, indicating increasing transverse pelvic dimensions with more advanced prolapse (e.g., r = 0.42 to 0.58; p < 0.05). In anterior compartment prolapse, the same parameter measured during Valsalva and contraction correlated significantly with POP-Q point AA (e.g., r = 0.45 to 0.61; p < 0.05). Anteroposterior diameters and genital hiatus area were also analyzed but showed weaker or inconsistent correlations. AI integration facilitated real-time image segmentation and automated measurement, reducing operator dependency and increasing reproducibility. These findings highlight the laterolateral diameter as a strong, reproducible anatomical marker for POP severity, particularly when assessed dynamically. The combined use of AI-enhanced imaging and functional indices provides a novel, standardized, and objective approach for assessing pelvic floor dysfunction. This methodology supports more accurate diagnosis, individualized management planning, and long-term monitoring of pelvic floor disorders. Full article

The CORE complex refers to the muscles of the core region of the body, including the abdominal muscles, lower back muscles, and diaphragm. Among the various techniques aimed at improving CORE strength and functionality, abdominal hypopressive techniques have gained popularity. Objectives: To evaluate the available scientific literature on the effects of AHT on the CORE complex. Methods: A systematic search was conducted in January 2025 in PubMed, Web of Science, PEDro, Cochrane, ClinicalTrials.gov and Scopus. Only randomized controlled trials (RCTs) involving adults were included. Two reviewers independently selected studies and extracted data. The review was registered in PROSPERO (CRD-42023424933) and followed PRISMA guidelines. Results: Of 258 studies identified, 13 of them met the eligibility criteria for the final review. Showing the application of abdominal hypopressive techniques could have positive effects on the pelvic floor, transverse abdominis muscle, lumbar region, and diaphragm. The average methodological quality of the articles is 6.6 according to the PEDro scale. The risk of bias was high in 12 articles. Conclusions: Although the results show improvements in the CORE muscles after applying abdominal hypopressive techniques, further research is necessary to confirm these findings, given the insufficient methodological quality of the scientific literature and its high risk of bias.

Background/Objectives: Urinary tract infections (UTIs) are the most common bacterial infections and one of the most common diseases worldwide. These infections induce an enormous financial and economic burden. The most frequent pathogen in UTIs is Escherichia coli (E. coli), which is responsible for over 85% of cases of cystitis and over 60% of recurrent cases. Repeated antibiotic prescriptions increase the risk of bacteria developing resistance, reducing treatment efficacy and limiting long-term therapeutic options. When traditional preventive methods fail to provide protection, other strategies may be necessary. To investigate the effectiveness of vaccination with Uro-Vaxom for the prevention of UTIs based on currently available studies. Methods: Systematic literature search. Results: The available studies focus almost exclusively on the female sex. Uro-Vaxom decreased the recurrence of UTIs, was overall well tolerated, and reduced the need for antibiotic therapies. Conclusions: Uro-Vaxom is a potential effective and well-tolerated option for reducing the recurrence of UTIs in patients prone to frequent infections. Nevertheless, the retrospective nature of several studies, combined with methodological limitations and variability in study design, precluded a reliable quantitative estimation of the treatment effect.

Background: Chemoresistance and tumor recurrence remain major obstacles in colorectal cancer (CRC) therapy. Elucidating the molecular mechanisms underlying treatment resistance is critical for improving therapeutic outcomes. Methods: We analyzed transcriptomic profiles from public datasets (TCGA and GSE39582) to identify differentially expressed genes associated with a poor response to neoadjuvant chemotherapy in CRC patients. Among 298 candidate genes, ANXA9 emerged as significantly overexpressed in chemoresistant tumors and associated with a poor prognosis. These findings were further validated in an independent cohort of 146 Stage III CRC patients using immunohistochemistry and survival analysis. The expression of ANXA9 was evaluated in oxaliplatin acquired-resistant CRC cell lines via qPCR and Western blot. Functional studies, including RNA interference, colony formation, apoptosis assays, and drug sensitivity testing, were performed in vitro and in vivo to assess the role of ANXA9. A high-throughput drug screen identified G749, a FLT3 inhibitor, as a potential therapeutic agent. Results: ANXA9 expression was significantly elevated in non-responders to chemotherapy and oxaliplatin-resistant CRC cell lines. The knockdown of ANXA9 reduced proliferation and enhanced oxaliplatin sensitivity. G749 was found to suppress ANXA9 expression in a dose-dependent manner and inhibit CRC cell growth in vitro and in patient-derived organoids. In a CRC xenograft mouse model, G749 reduced the tumor burden without observable toxicity. Mechanistically, we identified ZMYM2 as a transcriptional regulator of ANXA9. ChIP-qPCR confirmed ZMYM2 binding to the ANXA9 promoter, especially in resistant cells. Silencing ZMYM2 suppressed tumor cell growth and restored chemosensitivity. Conclusions: The ZMYM2-ANXA9 signaling axis drives chemoresistance and tumor progression in CRC. FLT3 inhibition by G749 effectively downregulates ANXA9 and sensitizes tumors to chemotherapy, highlighting a novel therapeutic approach for chemoresistant CRC. Full article
