CTC monitoring tracks therapy response and disease progression in advanced cancers. Publications | 7 June 2022 ASCO 2022: CTCs as a biomarker for monitoring: Disease progression, treatment response, and minimal residual disease. Study of 127 patients shows CTCs are a dynamic biomarker for monitoring disease progression and therapy response in advanced epithelial cancers. Background To analyze the role of circulating tumor cells (CTCs) as a confirmatory personalized biomarker for monitoring disease progression, disease burden, and minimal residual disease in epithelial origin cancers. Methods In this retrospective study, 127 patients with colorectal, breast, and ovarian cancer at stage III and IV were analyzed. The patients were at various stages of intensive chemo and radiotherapy while the CTCs were isolated and enumerated from 1.5 ml of blood. The decision to continue chemotherapy or change to oral metronomic therapy was based on the presence of circulating tumor cells in Stage III. While in stage IV, serial measurement of CTCs guided therapy. CTCs were isolated using the OncoDiscover platform possessing EpCAM antibody-based immunomagnetic targeting of magnetic nanoparticles after RBC lysis. CTCs were imaged and identified as CK18+ and CD45- cells showing a well-defined nucleus using a motorized fluorescence microscope operational with a monochrome camera. CTCs were enumerated using automated image analysis software and counts were expressed as the number per 1.5 ml of blood. Results In this retrospective study, we analyzed blood samples from 127 patients with advanced-stage epithelial cancers (breast: 50%, ovarian: 27%, colorectal: 23%) for the presence of CTCs. Amongst those, 52% showed the presence of CTCs (breast: 52%, ovarian: 46%, colorectal: 58%). The CTC count ranged between 1-5 / 1.5 ml of blood with mean and median values of 2 and 1. Among the CTC positive population, the majority had a CTC count of 1 (44.4%), while more than 2 CTCs were observed in 11% of the population. CTC clusters were detected in 13% of the population, which predominantly were stage IV patients. 67% among the follow-up patients showed a decrease in CTC count from the baseline due to the prescribed treatment, while 22% of patients showed an increase in CTC count from the baseline. 11% of patients did not show a change in CTC count from the baseline. When CTC count was investigated as an independent variable to monitor the therapeutic response, it correlated well with positive or negative outcomes. In a few representative cases, the reduction of CTC numbers from the basal value was indicative of effective treatment. Exceptionally, in a representative colorectal cancer case, a PET scan showed no primary as well as secondary tumor burden, but the presence of CTCs in blood led to further investigating an abdominal MRI that indicated multiple liver lesions suggesting micro-metastasis. Subsequent to SIRT treatment, the patient showed complete tumor regression and the absence of CTCs in peripheral blood. Conclusions Our data suggest that CTCs can serve as a dynamic intermittent biomarker for monitoring disease progression in advanced stages and assessing the therapeutic response, thus emphasizing the role of CTCs in personalized cancer management.

CTCs, clusters, and PD-L1 expression indicate MRD and guide endometrial cancer care. Publications | 3 November 2025 PD-L1 over-expression on Circulating Tumor Cells in Endometrial Cancer Patients This study demonstrates a high prevalence of CTCs in the endometrial cancer population. The presence of CTCs, CTC clusters, and PD-L1–overexpressing CTCs indicates occult minimal residual disease, disease aggressiveness, and potential progression toward metastasis. Introduction The risk of recurrence in non-metastatic endometrial cancer (EC) within 2–3 years is significant, ranging from 6% to 21%. Lymph node involvement is a key determinant of outcome prediction in patients with operable EC. To improve prognostic accuracy, particularly in the context of curative-intent surgery and adjunct therapy regimens, biomarkers such as circulating tumor cells (CTCs) have not been extensively evaluated in EC. The presence of CTCs as an occult disease component in EC may represent minimal cellular residual disease (MCRD) and could play a role in the metastatic cascade and invasion to distant organs. In this study, we evaluated the distribution of CTCs, their PD-L1 overexpression, and the occurrence of CTC clusters in EC patients. Methods A total of 154 blood samples were retrospectively analyzed, including 133 baseline and 21 follow-up samples (1.5 mL each). CTCs were isolated using the CDSCO India–approved OncoDiscover® CTC Test, which employs immunomagnetic enrichment targeting epithelial cell adhesion molecule (EpCAM). CTCs were identified based on immunocytochemical staining as CK18⁺, DAPI⁺, and CD45⁻ cells with distinct morphological features. Fluorescence imaging was performed using a Zeiss Axio Observer 7 microscope, and signal intensities were quantified to assess associations with clinicopathological parameters. PD-L1 expression on CTCs was evaluated through fluorescence-based immunostaining and quantified accordingly. Statistical analyses summarized total CTC counts, PD-L1–positive CTCs, and the presence of CTC clusters. Results A total of 336 CTCs were detected in 116 patients (75.3%). PD-L1 overexpression on CTCs was observed in 52.6% of samples (81 out of 154). Across all 154 patient samples analyzed, the mean values were 1.54 for total CTCs, 0.14 for CTC clusters, and 1.23 for PD-L1–positive CTCs. Notably, 21 patients (13.6%) demonstrated the presence of CTC clusters, accounting for 121 of the 336 total CTCs, suggesting more aggressive disease behavior. The highest proportion of patients belonged to the 61–70-year age group (41.55%). Conclusions This study demonstrates a high prevalence of CTCs in the endometrial cancer population. The presence of CTCs, CTC clusters, and PD-L1–overexpressing CTCs indicates occult minimal residual disease, disease aggressiveness, and potential progression toward metastasis. PD-L1 expression on CTCs may have implications for immunotherapy decision-making, particularly in situations where tissue biopsy is unavailable. View Publication Stay One Step Ahead of Cancer.

Actorius Innovations at ASCO 2026 Publications | 17 March 2026 ASCO 2026: Comparative enumeration of circulating tumor cells with PD-L1 over expression using anti EpCAM antibody to N-Cadherin in solid cancers Dual EpCAM and N-cadherin profiling improves circulating tumor cell detection, enhancing minimal residual disease surveillance and identifying metastasis-prone cells. Abstract Background Minimal cellular residual disease (MCRD) with PD-L1 expression on circulating tumor cells (CTCs) is highly evidenced for possible aggressive diseases systemically. CTCs captured using N-cadherin—a calcium-dependent transmembrane glycoprotein—targets epithelial-mesenchymal transition (EMT) tumor cells. There is a difference in phenotypic specificity, as EpCAM likely misses CTCs that have undergone EMT, while N-cadherin enables the detection of these aggressive, invasive cells. Thus, N-cadherin-based CTC capture is more effective for identifying metastasis-prone CTCs. Using both markers together may improve overall CTC capture efficiency to provide a more comprehensive landscape of tumor heterogeneity and disease progression. We show the comparative and paired outcome of CTC capture using both anti-EpCAM antibodies versus N-cadherin across solid cancers. Methods Retrospectively, we compared 33 patients with different stages of breast, rectal, colon, prostate, lung, and other cancers. CTCs were detected using an affinity marker-independent isolation platform to avoid EpCAM bias. CTCs were isolated using a marker-independent, anti-EpCAM-positive, and N-cadherin-positive OncoDiscover platform evaluating PD-L1+ expression using automated Zeiss microscopy. Anti-EpCAM-positive and N-cadherin-positive CTCs were classified using validated intensity thresholds, concordance/discordance rates, cluster frequency, and the mean distribution of CTCs. Results OncoDiscover platform EpCAM and N-cadherin expression showed an overall concordance of 60.61% and a discordance of 39.39%, indicating EMT-related phenotypic divergence. The mean CTC counts were comparable between anti-EpCAM-positive and N-cadherin-positive samples (0.66 and 0.70 per sample, respectively). Among EpCAM-positive CTCs, 42.85% expressed PD-L1, whereas PD-L1 positivity was lower and present in 30.30% of N-cadherin-positive CTCs. Importantly, 4 N-cadherin+/EpCAM- PD-L1-positive CTCs were identified, which were not captured by EpCAM affinity; conversely, 6 EpCAM+/PD-L1+ CTCs lacked N-cadherin expression. Notably, CTC clusters were found in 12.12% of EpCAM+ cases and 6.06% of N-cadherin-positive cases. Collectively, these findings demonstrate that dual-marker profiling improves detection sensitivity relative to single-marker interrogation. Conclusions Using both EpCAM and N-cadherin together improved CTC capture efficiency. However, N-cadherin-based CTC capture is more implicative in identifying metastasis-prone CTCs. The dual affinity accounts for CTCs for MCRD surveillance for the presence of disease systemically and is indicative of the progression of micro-metastasis.

Inverse 3D lab-on-chip microfilms for selective CTC capture from blood. Publications | 15 July 2024 Manuscript: Inverse 3D ‘lab-on-a-chip’ polymeric microfilms for selective capture of circulating tumor cells from patients' blood Inverse 3D lab-on-chip microfilms for selective CTC capture from blood. Engineering inverse 3D polymeric microfilms with controlled spatial hierarchy is both highly challenging and critically important at the intersection of biology and materials science. These structures hold significant potential for enhancing selective cell–surface interactions, including cell adhesion and growth. Protein-modified inverse 3D polymeric microfilms can further promote selective cell capture and adhesion. In this study, we report the fabrication of inverse 3D polymeric microfilms using composite polymeric–bioligand conjugated films designed to enhance the capture of circulating tumor cells (CTCs) from the blood of cancer patients. The microfilms were developed using functionalized poly(lactic acid) (PLA) and poly(lactic-co-glycolic acid) (PLGA), mediated with the ligand transferrin. Protein immobilization on the films was achieved by conjugating transferrin (Tf), collagen (Co), and bovine serum albumin (BSA) to promote cellular adhesion and capture. The films were characterized using scanning electron microscopy (SEM), attenuated total reflectance infrared spectroscopy (ATR-IR), and contact angle measurements, revealing micropores ranging from 18–26 μm. Confocal laser scanning microscopy (CLSM) demonstrated enhanced cell attachment on the polymeric-blend microfilms, confirming improved cell adhesion, capture, and the ability of cells to proliferate within the 3D structure. The inverse 3D polymeric microfilms achieved an 80% cell capture efficiency with cultured cancer cells. In clinical utility, their CTC capturing efficiency was comparable to OncoDiscover® CTC enumeration technology. These inverse 3D polymeric microfilms represent a novel ‘lab-on-a-chip’ platform capable of enabling CTC enumeration for monitoring minimal residual disease (MRD), tracking metastatic progression, evaluating treatment response, and enabling early detection of relapse.

Actorius Innovations at ASCO Annual Meeting 2026 Publications | 17 March 2026 ASCO 2026 : Association of circulating tumor cells with PD-L1 expression and clusters in confirmative tumor thrombus in selective solid cancers. Study shows circulating tumor cells with PD-L1 expression in tumor thrombus patients, indicating active dissemination and potential metastatic risk. Abstract Background Tumor thrombus (TT) refers to the direct extension of tumor cells into a blood vessel and is often detected incidentally. It is commonly observed in renal cell carcinoma (RCC), hepatocellular carcinoma (HCC), and Wilms tumor. The presence of TT significantly worsens prognosis and alters disease staging. TT is frequently located in vessels such as the renal vein, inferior vena cava, and portal vein, requiring multidisciplinary evaluation due to its aggressive nature and risk of obstruction or embolization. Diagnostic differentiation between tumor thrombus and a “bland” thrombus (blood clot) typically relies on imaging techniques such as CT or MRI. In this study, we evaluated the association and potential role of circulating tumor cells (CTCs) expressing immune-relevant markers, such as PD-L1, in patients with tumor thrombus. The presence of CTCs originating from TT margins may help refine risk stratification and therapeutic decision-making. Methods In this observational study, 12 patients aged 51–80 years with confirmed tumor thrombus were analyzed. The cohort included patients with hepatocellular carcinoma (HCC, n = 4), pancreatic cancer (n = 3), liver cancer (n = 3), renal cell carcinoma (RCC, n = 1), and gallbladder cancer (GB, n = 1). Blood samples were analyzed for the presence of CTCs with PD-L1 expression at baseline, and three patients also had follow-up samples. Samples were processed using the CDSCO-approved OncoDiscover CTC enrichment technology. CTCs were identified using an automated Zeiss microscope based on EpCAM⁺, CK18⁺, DAPI⁺, CD45⁻, and PD-L1⁺ markers. Results A total of 16 CTCs were detected in 10 patients (83.33%) from 1.5 mL blood samples, with counts ranging from 1 to 6 CTCs per patient. At baseline, patients with HCC, pancreatic, RCC, gallbladder, and other cancers showed the presence of PD-L1–expressing CTCs. Follow-up samples revealed persistent CTC positivity, although the number of PD-L1–positive CTCs decreased. The mean CTC distribution was 1.33 for CK18-expressing CTCs. PD-L1–positive CTCs were detected in a substantial subset, with a mean distribution of 0.67 (9 CTCs among 12 patients), indicating immune-evasive potential. CTC clusters were rare and detected in only one HCC patient but persisted during follow-up. Both male and female patients demonstrated comparable CTC positivity. Conclusion The presence of CTCs in peripheral blood highlights active tumor cell dissemination from tumor thrombus margins. Although CTC clusters were infrequent, their occurrence may indicate an increased metastatic risk. This study demonstrates, for the first time, the presence of CTCs originating from tumor thrombus margins entering systemic circulation. Further studies are required to better understand their clinical implications. View Publication Stay One Step Ahead of Cancer.
