• Financial toxicity as a structural barrier to cervical cancer treatment in Sub-Saharan Africa.
    1 week ago
    Cervical cancer remains one of the most common and preventable cancers among women in sub-Saharan Africa. Despite established curative treatments, most women present with locally advanced disease and many fail to complete therapy. Financial toxicity encompassing, direct medical costs, non-medical expenditures, income loss, and psychological distress, is an underrecognized but potentially important contributor to this treatment gap. This narrative review examines evidence on the magnitude, structural drivers, and consequences of financial toxicity in cervical cancer care across sub-Saharan Africa, and proposes system-level mitigation strategies. Targeted searches of PubMed, Embase, and Google Scholar (January 2013-April 2026), were supplemented by gray literature and reports from international health agencies. Thematic synthesis was conducted along the cervical cancer care continuum within a universal health coverage financial risk protection framework. The reviewed evidence suggests that financial toxicity is multi-dimensional, cumulative, and largely shaped by health-system organization. Quantitative studies report substantial out-of-pocket expenditure and catastrophic health spending, while qualitative studies consistently describe severe financial hardship, although definitions and measurement approaches vary across studies. Centralized radiotherapy services, requiring repeated long-distance travel over 5 to 6 weeks, appear to be an important structural contributor through transport, accommodation, and income-related costs. Available evidence further suggests that financial toxicity may contribute to delayed treatment initiation, missed radiotherapy sessions, incomplete chemoradiation, and treatment abandonment. This review also raises the hypothesis that, in radiotherapy-constrained settings, treatment pathway adaptation such as neoadjuvant chemotherapy followed by surgery may have financial as well as oncologic implications that warrant prospective evaluation. Direct evidence linking financial toxicity to survival outcomes remains limited. Reducing financial barriers will likely require health-system reforms, including decentralized service delivery where feasible, integration of financial navigation into oncology services, universal health coverage benefit packages covering the full cervical cancer care continuum, and treatment protocols that account for patients' financial burden.

  • Pathologic complete response after first-line tislelizumab, cetuximab, and dabrafenib in microsatellite-stable BRAF V600E-mutant metastatic colorectal cancer: a case report.
    1 week ago
    BRAF V600E-mutant metastatic colorectal cancer (mCRC) is characterized by aggressive disease behavior and limited responsiveness to conventional systemic therapy. Although BRAF/EGFR-targeted therapies have improved clinical outcomes, durable complete remission remains uncommon, particularly in microsatellite-stable (MSS) disease. We report the case of a 26-year-old woman with MSS, BRAF V600E-mutant sigmoid colon adenocarcinoma and synchronous liver and omental metastases (cT4aN2M1c, stage IVC). Pretreatment biopsy demonstrated high programmed death-ligand 1 (PD-L1) expression (combined positive score = 20) and a high density of intratumoral CD8+ T cells (350 cells/mm2). Because the patient declined cytotoxic chemotherapy, first-line treatment consisted of tislelizumab combined with cetuximab and dabrafenib. After approximately 4 months of systemic therapy, radiological assessment showed a partial response, accompanied by normalization of serum marker levels, enabling conversion surgery. Histopathological examination confirmed a pathological complete response in the primary tumor and all resected metastatic lesions. A personalized tumor-informed circulating tumor DNA assay performed 3 months after surgery was negative. At the latest follow-up (35 months after treatment initiation), the patient remained free of clinical and radiological evidence of disease recurrence. This case highlights the possibility that selected patients with MSS, BRAF V600E-mutant mCRC may achieve durable remission with combined programmed cell death protein 1 blockade and dual-targeted therapy. The observed association between high intratumoral CD8+ T-cell infiltration, elevated PD-L1 expression, and favorable treatment response should be considered hypothesis-generating and requires validation in prospective biomarker-driven studies.

  • Recent advances in discriminating prostate cancer from benign prostatic diseases in the pre-biopsy population.
    1 week ago
    Prostate cancer (PCa) remains one of the most prevalent malignancies and a major cause of cancer-related deaths among men worldwide. Current pre-biopsy evaluation relies primarily on serum prostate-specific antigen (PSA) testing and multiparametric MRI (mpMRI), but both approaches have limited specificity, particularly in the diagnostic gray zone (PSA 4-10 ng/mL and/or equivocal MRI findings such as Prostate Imaging Reporting and Data System (PI-RADS) category 3 lesions). In this setting, overlap between PCa and benign prostatic diseases frequently leads to unnecessary biopsies. This unmet clinical need has driven the development of novel diagnostic strategies designed to better discriminate PCa from benign prostatic diseases before biopsy. In this review, we provide a comprehensive overview of recent advances in non-invasive diagnostic strategies, including liquid-based molecular biomarkers, advanced imaging modalities, and multimodal integrative frameworks. These advances may improve diagnostic accuracy, reduce unnecessary biopsies, and support personalized risk stratification and biopsy decision-making. Moreover, we highlight the paradigm shift from single-parameter screening to multimodal integration, including artificial intelligence-based approaches in early PCa screening. Overall, these non-invasive strategies may help reduce diagnostic uncertainty in the gray zone and support more precise and personalized biopsy decision-making.

  • VEGF pathway signalling across pulmonary neuroendocrine tumours: associations with histological subtypes in a multicentre study.
    1 week ago
    The current classification of pulmonary neuroendocrine neoplasms (NENs) is primarily based on histomorphological criteria, which do not fully capture their underlying biological heterogeneity. This limitation is particularly evident among pulmonary carcinoids, a subgroup characterized by highly variable clinical behaviour and prognostic outcomes despite similar morphological features.Angiogenesis is a hallmark of NENs, yet the role of the vascular endothelial growth factor (VEGF) pathway in pulmonary NENs remains incompletely defined.In this multicentre retrospective study, 109 pulmonary NENs (67 typical carcinoids, 22 atypical carcinoids, and 20 high-grade NENs) were analysed. VEGF, VEGFR1, VEGFR2, and VEGFR3 expression was assessed by immunohistochemistry and correlated with clinicopathological features and outcome.VEGF pathway components showed subtype-specific expression patterns. VEGFR1 was reduced in high-grade tumours and displayed a bimodal distribution, while VEGFR2 and VEGFR3 were higher in atypical carcinoids and high-grade tumours. Survival and recurrence were driven by histological subtype, whereas VEGF pathway expression lacked independent prognostic significance.The higher expression of VEGFR2 and VEGFR3 observed in atypical carcinoids and high-grade neuroendocrine carcinomas suggests a possible involvement of the VEGF signalling pathway in tumour biology. These findings contribute to the biological characterization of pulmonary NENs and provide a rationale for future studies investigating whether VEGF pathway markers may have predictive relevance for anti-angiogenic therapies.

  • Single-cell and spatial transcriptomics identify a JUNB+ neutrophil subset enriched in immune-excluded regions of lung adenocarcinoma.
    1 week ago
    Tumor-associated neutrophils (TANs) display functional plasticity in lung adenocarcinoma (LUAD), but subsets linked to immune exclusion are poorly defined.

    We integrated single-cell RNA-seq, spatial transcriptomics, and bulk multi-omics data to characterize neutrophil heterogeneity in LUAD. Key findings were validated by immunofluorescence co-localization and qPCR on clinical blood and isolated neutrophils.

    Neutrophils exhibited the highest scores for an EMT-associated transcriptional program and immune exclusion among all immune cell types. A distinct JUNB+ neutrophil subpopulation was spatially enriched in immune-excluded tumor regions and correlated with unfavorable prognosis. Spatial transcriptomic analysis revealed a significant positive correlation between JUNB expression and neutrophil marker module scores across tissue spots (Pearson r = 0.216 and 0.205, P = 1.84 × 10^-10 and 9.06 × 10^-11). Immunofluorescence confirmed JUNB protein co-localization with CD66b+ neutrophils in LUAD tissues (54.3% ± 8.2% of CD66b+ cells JUNB +). qPCR revealed specific upregulation of JUNB mRNA in circulating neutrophils from LUAD patients, whereas no difference was observed in whole blood.

    This study identifies JUNB as a marker of a neutrophil state associated with immune exclusion and poor prognosis in LUAD. The neutrophil-specific upregulation of JUNB highlights its potential as a circulating biomarker for TAN-mediated immunosuppression, which warrants validation in prospective cohorts.

  • Menin inhibition in pediatric UBTF-TD myelodysplastic syndrome: molecular rationale and clinical observation.
    1 week ago
    UBTF tandem duplications (UBTF-TD) define a recently recognized high-risk subtype of pediatric myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). UBTF-TD myeloid neoplasms are driven by a HOX/MEIS1 transcriptional program that depends on the interaction between menin and KMT2A. Preclinical studies have shown sensitivity to menin inhibition, but clinical experience in children with MDS remains scarce.

    We report a ten-year-old girl with MDS with excess blasts harboring UBTF-TD together with NRAS and WT1 mutations. During the first cycle of azacitidine and venetoclax, blood counts did not improve, and the patient remained dependent on platelet and red blood cell transfusions. Revumenib was added to the ongoing treatment. Within two weeks, platelet counts and hemoglobin increased markedly, the patient became transfusion independent, and bone marrow blasts cleared. UBTF-TD also became undetectable by molecular testing. The patient subsequently underwent allogeneic hematopoietic stem cell transplantation and remains in complete remission with full donor chimerism one year after transplantation.

    The rapid hematologic recovery and clearance of both bone marrow blasts and detectable UBTF-TD after initiation of revumenib provide clinical evidence that the menin dependency of UBTF-TD myeloid neoplasms can be therapeutically exploited. The timing and depth of the clinical and molecular response were remarkable.

  • Ataxia-Telangiectasia, DNA Repair Deficits, Immune Dysfunction, and Cancer: A Review of Mechanisms, Clinical Presentations, and Emerging Therapies.
    1 week ago
    Ataxia-Telangiectasia (A-T) is a rare, autosomal recessive disorder caused by biallelic pathogenic variants in the ATM gene. Loss of ataxia-telangiectasia mutated (ATM) protein function impairs DNA damage responses, leading to progressive neurodegeneration, genomic instability, immunodeficiency, and an increased risk of malignancy. Some A-T patients develop cancers at a young age and display extreme sensitivity to ionizing radiation and certain chemotherapeutics. Therefore, standard treatments often cause severe, life-threatening toxicities in these patients. This review discusses the dual role of ATM as a tumor suppressor and key DNA repair kinase, the mechanisms by which ATM deficiency promotes oncogenesis, and the unique challenges of treating malignancies in the context of A-T. We highlight emerging, less genotoxic therapies for ATM-deficient cancers including cancer vaccines, immune checkpoint inhibitors, CAR T-cell therapy, and synthetic lethal approaches such as Poly(ADP-ribose) polymerase (PARP) and Ataxia Telangiectasia and Rad3-related (ATR) inhibitors. These novel strategies may improve outcomes for A-T patients while minimizing treatment toxicity. We also outline future directions and clinical implications, emphasizing the need for tailored therapeutic approaches and multidisciplinary care for this high-risk population. Because prospective, A-T-specific therapeutic data are scarce, we draw extensively on the broader literature on somatic ATM-mutant cancers to inform management, while highlighting the additional constraints imposed by germline ATM loss.

  • Primary Aortic Wall Myxoma Presenting With Recurrent Systemic Embolization: A Hybrid Surgical Management Strategy.
    1 week ago
    Primary aortic wall myxoma is exceptionally rare and may mimic mural thrombus or acute aortic dissection.

    A 38-year-old man presented after approximately 12 hours of acute left lower-limb ischemia with concomitant left upper-limb occlusion. Computed tomography angiography showed filling defects in the ascending and descending thoracic aorta. Recurrent embolization after peripheral thromboembolectomy prompted emergency ascending aortic exploration. A friable intramural myxoma was excised with ascending aortic graft replacement; the descending lesion was excluded by staged thoracic endovascular aortic repair while therapeutic anticoagulation was maintained.

    Histopathology confirmed an aortic wall myxoma. The case illustrates the limitations of imaging and an individualized hybrid strategy for suspected multifocal aortic involvement.

    Recurrent embolization after embolectomy should prompt urgent proximal-source control. Hybrid repair may be considered when anatomy and clinical urgency support it.

  • SLC35F2 in Cancer Development and Progression.
    1 week ago
    Solute carrier family 35 member F2 (SLC35F2) is a transporter located predominantly at the plasma membrane and Golgi apparatus and is predicted to contain ten transmembrane helices. Recent studies have identified SLC35F2 as the only currently known queuosine (Q)-specific transporter in human cells and as the principal high-affinity transporter of queuine (q), although it is not the absolutely exclusive route for q uptake. SLC35F2 is also aberrantly expressed in multiple cancers and has been associated with cell proliferation, migration, invasion, chemoresistance, and ferroptosis regulation. However, the available evidence derives mainly from database analyses, individual cell-based studies, and limited animal experiments and does not yet demonstrate that its tumor-promoting effects directly depend on q/Q uptake or tRNA queuosine modification. SLC35F2 is also an important uptake transporter for the anticancer agent YM155, and its expression can influence intracellular drug exposure and DNA-damage toxicity. YM155 was initially classified as a survivin transcriptional inhibitor, but subsequent studies indicate that its actions also involve DNA intercalation and oxidative DNA damage. Previous clinical trials did not prospectively stratify patients by SLC35F2 expression and showed limited overall efficacy; consequently, its clinical value remains translationally uncertain and biomarker-dependent. Using a structured narrative-review approach, this article critically evaluates the structure and localization of SLC35F2, q/Q transport, regulation of its expression and protein stability, tumor-associated functions, and YM155 delivery. It distinguishes replicated mechanisms from findings supported by single studies and from testable hypotheses, thereby providing a framework for future mechanistic research and precision drug delivery.

  • Relationship Between Benign Intracranial Tumor Location and the Side of Spontaneous Cerebrospinal Fluid Leak.
    1 week ago
    AIM: To present cases of spontaneous cerebrospinal fluid (CSF) rhinorrhea and otorrhea, and to conduct a systematic literature review examining the relationship between benign tumor location and the leak side. MATERIAL and METHODS: A PRISMA-based systematic review was conducted to evaluate studies on spontaneous CSF leaks caused by benign intracranial tumors, alongside three newly reported cases. RESULTS: All three cases exhibited CSF leaks ipsilateral to the tumor: Case 1 involved a pituitary ACTH-secreting macroadenoma with rhinorrhea; Case 2, a pineocytoma with hydrocephalus and nasal encephalocele; and Case 3, a petromastoid meningioma with otorrhea. In the systematic literature review, 28 of 125 studies met the inclusion criteria. The median patient age was 42 years, with a male-to-female ratio of 16:12. Macroprolactinoma was the most frequent tumor (25%), primarily located in the sella (46.4%). Tumors were located at the midline (39.3%), right side (35.7%), or left side (25%). The sphenoid sinus was the most common site of CSF leak (39.3%). The leak occurred through the right nostril (39.3%), left nostril (39.3%), both nostrils (10.7%), right ear (7.1%), and both the nostril and ear (3.5%). Hydrocephalus was present in 25% of cases. CONCLUSION: Although our cases demonstrated ipsilateral leaks, the literature review revealed equal rates of left-sided rhinorrhea, even with midline or right-sided tumors, suggesting skull base bone destruction alone does not explain CSF leaks, particularly in benign intracranial tumors outside mastoid involvement. Careful patient history regarding the side of rhinorrhea, comprehensive preoperative imaging, and hydrocephalus evaluation are essential for identifying the leak site and preventing complications, such as recurrent meningitis.
