Poor response to systemic therapy upon progression on cyclin dependent kinase 4/6 inhibitors in HR+ Inflammatory Breast Cancer
(SABCS 2025)
- "RESULTS Among N = 33 patients evaluated, upon progression on standard of care CDKI and endocrine directed therapy (ET) combinations, patients received the following therapies with median ToT (months (min-max ToT)), respectively: capecitabine (N = 7; 3 (2-5)), everolimus/ET (N = 6, 3 (1-4)), Abraxane (N = 3, 3(2-10)), Eribulin (N = 2, 2.5(2-3)), capivasertib/fulvestrant (N = 1, 6(6)), taxol (N = 1, 5(5)), elacestrant (N = 1, 3(3)), fulvestrant (N = 1, 3(3)), tamoxifen (N = 1, 1(1)), intrathecal topotecan (N = 1, 1(1)), non standard/clinical trial (N = 4, 2.5(1-4)). CONCLUSION Patients with metastatic HR+ IBC demonstrate poor response to ET and cytotoxic chemotherapies upon progression on first line standard CDKI/ET, with a disproportionately high rate of death occurring in the first line setting due to advanced disease. Given previously reported low ToT on CDKI/ET in the first line and high incidence of brain relapse in this population, clinical trial design utilizing..."

Monitoring therapy in leptomeningeal carcinomatosis in colorectal cancer using CSF liquid biopsy.
(SNO 2025)
- "In addition to systemic therapy, this patient was initially treated intrathecally with nivolumab, methotrexate, and topotecan, then weekly with intrathecal methotrexate. We show some discrepancy between CSF tumor load as measured by SNV and levels of chromosomal structural gain or loss. In summary, we show that longitudinal monitoring of LC using CSF LBx provides a reliable means for evaluating efficacy of therapy and perhaps can guide therapeutic plans."

Non-enhancing regions of Glioblastoma Harbor Quiescent Stem Like Cells that Contribute to Chemotherapy Resistance
(SNO 2025)
- "Cells were treated with temozolomide (TMZ, 1000 μM), paclitaxel (PTX, 50 μM), topotecan (TPT, 50 μM), vincristine (VCR, 50 μM), and doxorubicin (DOX, 20 μM) for 48 hours. NE infiltrating regions of glioblastoma maintain high proportions of cells that have characteristics of glioma stem cells transcriptionally. These regions have slow initial growth in in vitro and in vivo models, but are able to recapitulate solid tumor properties. Likely related to this quiescent property, NE regions are more resistant to chemotherapeutic agents."

Enhancing drug retention in H3 K27-altered diffuse midline glioma: Combining convection-enhanced delivery with systemic efflux inhibition
(SNO 2025)
- "However, systemic everolimus administration prolonged drug retention and potentiated the effects of efflux substrate drugs delivered via CED (e.g., topotecan, ponatinib). The observed synergistic effects highlight a promising strategy to overcome drug clearance limitations and improve treatment outcomes. Further clinical investigation is warranted to validate this approach in patients."

Application of surface-enhanced Raman scattering combined with artificial intelligence for multiplex detection of chemotherapeutic agents used in solid tumors.
(PubMed, Anal Bioanal Chem)
- "Carboplatin, epirubicin, gemcitabine, paclitaxel, topotecan, and docetaxel are widely used in combination regimens; however, there is still a lack of sensitive, rapid, and multiplex technologies for real-time monitoring of chemotherapeutic drug concentrations. Within the simulated therapeutic concentration range, quantitative regression yielded R2 ≥ 0.98. This AI-SERS platform offers advantages of multiplex detection, trace-level sensitivity, and strong anti-matrix interference, holding great promise for pharmacokinetic monitoring and individualized chemotherapy optimization across a broad range of solid tumors."

A selective RPL15 PROTAC degrader enhances anti-PD-1 immunotherapy in a murine melanoma tumor model.
(PubMed, Oncogene)
- "We previously showed that topotecan, a chemotherapeutic drug and topoisomerase I (TOP1) inhibitor, binds to ribosomal protein RPL15 and induces the secretion of DAMPs from cancer cells, which activate cGAS-STING signaling in dendritic cells...Here, we synthesized SN-38-conjugated pomalidomide (SN38-PROTAC) and showed that SN38-PROTAC induced ubiquitin-mediated degradation of RPL15, but not TOP1...The enhanced antitumor effects of SN38-PROTAC and anti-PD-1 antibody combination were abolished in STING-deficient mice. Our results indicate that SN38-PROTAC, which induces RPL15 degradation, has the potential to enhance ICI efficacy in PD-1-resistant cancer with low cytotoxicity."

COLLATERAL SENSITIVIES EMERGE DURING THE EVOLUTION OF CHEMORESISTANCE TO MAP CHEMOTHERAPY IN OSTEOSARCOMA
(CTOS 2025)
- "Objective: We aimed to model the evolution of chemoresistance to methotrexate, doxorubicin, and cisplatin (MAP) in vitro and to characterize collateral drug sensitivity and resistance patterns over time, potentially informing second-line treatment strategies in chemo resistant primary or recurrent disease. Five evolutionary replicates of MG63.3 osteosarcoma cells were treated with six complete cycles of pulsed, clinically relevant doses of cisplatin and doxorubicin, alternating with methotrexate...Collateral resistance emerged to etoposide, vincristine, and topotecan, while sensitivity increased to gemcitabine, cabozantinib, and palifosfamide... Our model reveals temporally dynamic, heterogeneous collateral responses during the development of chemoresistance to MAP in osteosarcoma. While cross-resistance to several agents emerged, collateral sensitivity to gemcitabine and cabozantinib supports a second line use for these agents. These data may inform rational sequencing..."

Camptothecin in Cancer Therapy: Current Challenges and Emerging Strategies with Nanoemulsions.
(PubMed, Pharmaceutics)
- "Semi-synthetic analogs such as irinotecan (CPT-11) and topotecan (TPT) have been developed and approved for the treatment of various types of cancer; however, challenges related to drug resistance and side effects continue to arise. Therefore, nanomedicine and nanoparticle-based delivery systems, including nanoemulsions, liposomes, and antibody-drug conjugates (ADCs), emerge as promising strategies to improve the stability, bioavailability, and effectiveness of CPT, despite significant challenges such as scalability, pharmacokinetic variability, and regulatory requirements. This review discusses recent advances in CPT, its analogs, and these delivery platforms, highlighting its potential to optimize cancer therapy and reduce toxicity while outlining translational challenges such as scalability, pharmacokinetic variability, and regulatory requirements."

Investigation of Immunogenic Cell Death Induced by Cytotoxic Anticancer Agents in Small Cell Lung Cancer
(APSR 2025)
- "Methods : We verified the ability of various cytotoxic anticancer agents (cisplatin, carboplatin, etoposide, SN-38 (an active metabolite of irinotecan), and topotecan) to induce ICD in multiple human SCLC cell lines (H841, SBC3, SBC5, etc.). Flow cytometry analyses demonstrated that CRT expression on cell surface was robustly induced by exposure with etoposide and topotecan, while extracellular HMGB1 release was notably increased by exposure with carboplatin and etoposide. Conclusion : These findings suggest that carboplatin, etoposide, and topotecan efficiently induce ICD in SCLC cells, potentially offering new therapeutic options when combined with ICIs."
