  • ASCO 2022: A feasibility study of EMF (erlotinib+methotrexate+5-fluorouracil) regimen in recurrent HNSCC and role of CTCs in assessment of outcomes.

    EMF triplet therapy and CTC monitoring improve HNSCC outcomes and predict response. Publications | 7 June 2022 ASCO 2022: A feasibility study of EMF (erlotinib+methotrexate+5-fluorouracil) regimen in recurrent HNSCC and role of CTCs in assessment of outcomes. A phase II trial shows EMF triplet therapy is a safe, effective option for HNSCC, with CTCs serving as a promising biomarker for therapy response. Background Head and neck cancer is a huge burden in South East Asia with frequent relapse after curative therapy, while the rest present in advanced unresectable stages. Financial constraints for targeted and immunotherapy make it inaccessible for the bulk of the population. Thus, a low-cost but efficacious regimen is highly implicated. We assessed if the readily available triplet therapy of EMF is superior in terms of extending life and maintaining quality of life, along with the evaluation of CTCs as a predictive biomarker in such patients. Methods This was a single-arm, phase II, investigator-initiated interventional study, wherein 35 patients were enrolled. Platinum-resistant/refractory patients of HNSCC were treated with a combination of erlotinib 150 mg daily, methotrexate 40 mg/m2, and 5-fluorouracil 500 mg/m2 (d1, d8) q28 days till progression or unacceptable toxicities. The primary endpoint was the overall response rate (ORR) at 3 months; additional endpoints were disease control rate (DCR) at 3 months, overall survival (OS), progression-free survival (PFS), safety, and patient-reported quality of life (QOL). The role of CTCs in gauging the responders and non-responders was monitored using anti-Epithelial Cell Adhesion Molecule antibody-based enrichment on the OncoDiscover Drug Controller General of India (DCGI) approved platform. Results The ORR and DCR at 3 months were 45.7% and 68.5%, respectively. The median PFS was 5 months (95% CI: 3.9-6 months) and median OS was 9 months (95% CI: 7.4-10.5 months). The 3- and 6-month PFS rates were 86 ± 6% and 45 ± 9%, respectively, while OS rates at 3 and 6 months were 91 ± 5% and 68 ± 8%, respectively. Rash, mucositis, and fatigue were common adverse events occurring in 23 (65%), 14 (40%), and 9 (25.7%) patients respectively. The grade 3 events seen were rash in 5 (14.2%) and diarrhea in 2 (5.7%). Clinically significant improvement was seen in domains of role functioning, social functioning, fatigue, pain and global health status, swallowing, dryness of mouth, and feeling ill. The mean CTC count at baseline was 0.90 ± 1.1 / 1.5 ml of blood. Responders showed a decline in levels from 1.19 ± 0.25 to 0.33 ± 0.48, while non-responders had an increasing trend: 0.29 ± 0.48 to 1 ± 0.10 at 3 months (p = 0.010); with concordance rates with response being 52.9%. Additionally, CTC clearance at 3 months had a numerically better PFS of ~6 months (95% CI: 4.72-7.72) and OS of 10 months (95% CI: 2.3-5.65) vs 4 months (95% CI: 2.3-5.65), p = 0.258, and 8 months (95% CI: 4.3-11.6), p = 0.203 in those with persistence of CTCs. Conclusions The triplet regimen of EMF is a feasible, safe therapeutic option with favorable response rates and improved QOL in patients with platinum-resistant/refractory HNSCC. CTCs have a promising futuristic role as a predictive biomarker and can be extrapolated in the clinical upfront setting too. Clinical Trial Information CTRI/2020/02/023378.

  • Manuscript: Antibody mediated cotton-archetypal substrate for enumeration of circulating tumor cells and chemotherapy outcome in 3D tumors

    Antibody-coated cotton substrate for CTC enumeration and chemotherapy response. Publications | 18 February 2022 Manuscript: Antibody mediated cotton-archetypal substrate for enumeration of circulating tumor cells and chemotherapy outcome in 3D tumors Cotton microfluidic substrate enables efficient CTC isolation, 3D tumor growth, and drug response testing for improved cancer diagnostics and therapy research. Circulating tumor cells (CTCs) are distinct cancer biomarkers established in clinical settings for early cancer detection, metastasis progression, and minimal residual disease (MRD) monitoring. Despite numerous advances, comprehensive molecular characterization of CTCs remains extremely challenging due to their rarity and heterogeneity. Here, we present a novel cotton microfluidic substrate (CMS) as an innovative biomedical matrix that efficiently isolates CTCs while facilitating in vitro CTC expansion, enabling further downstream analysis of these rare cells. CMS enabled both static and dynamic isolation of cells from the MCF-7 cancer cell line, as well as from the blood of head and neck squamous cell carcinoma (HNSCC) patients. The cell capture efficiencies were further compared with the clinically regulated OncoDiscover® Liquid Biopsy Test. Furthermore, CMS served as a matrix on which the captured cancer cells were grown into 3D tumor models to study anti-cancer drug efficacy and multi-drug resistance (MDR) mechanisms. The design of the CMS employed two different surface chemistries—flattened and nanostructured surfaces—each conjugated with anti-EpCAM antibodies to evaluate CTC capture efficiency and 3D tumor growth dynamics. The nanostructured surface was highly efficient in capturing CTCs and promoted 3D tumor spheroid formation, showing a five-fold increase in size from day 3 to day 10 of culture. Moreover, when treated with the anti-cancer drug cisplatin, an almost half reduction in tumor size was achieved within 24 hours, followed by a cytostatic threshold and the eventual acquisition of drug resistance within three days. Conclusively, the CMS matrix exhibits potential for the further development of “tissue-on-chip” and “point-of-care” medical devices in cancer diagnostics, as well as for evaluating chemotherapeutic efficacy in drug discovery and development.

  • ASCO 2020: Device for the enumeration and continuous removal of circulating tumor cells in improving overall survival of epithelial cancer patients

    The POP device effectively removes CTCs from blood to reduce metastatic progression. Publications | 15 July 2020 ASCO 2020: Device for the enumeration and continuous removal of circulating tumor cells in improving overall survival of epithelial cancer patients The POP blood fluidic device safely removes CTCs with up to 100% efficiency, offering a new therapeutic path to reduce metastasis and improve survival. Background: The presence of circulating tumor cells (CTC) in the vascular system is a tell-tale signature of metastasis in epithelial origin cancers including lung, breast, colorectal and head and neck cancers. Noteworthy, about 90% of cancer deaths are due to the progression of metastasis. Yet, cancer therapy is focussed on inhibiting tumour growth and there is a paucity of options that target metastasis. We demonstrate the POP ‘device’ that removes circulating tumour cells (CTC) from a patient’s blood to reduce the metastatic progression and improve overall survival. Methods: We designed, multi-component glass beads enriched antibody EpCAM conjugate substrates as POP blood fluidic device. We characterized the substrate and accounted for the biocompatibility using whole blood of healthy volunteers. We evaluated, the acute toxicity of substrates using rat (Wistar Albino) whole blood (CPCSEA registration number: 941/PO/Re/S/06/CPCSEA; 31/07/2019) and further studied major histopathological tissues for any toxicity. Finally, we evaluated 06 cancer patients whole blood (1.5 mL) for capturing and for the elimination of CTCs. The captured cells were immuno-stained, and the optimal fluorescence acquisition intensity was critically quantified in accounting CK18 protein overexpression. Results: The multi-component antibody EpCAM based substrate exhibited efficient CTC capture ability with a mean capture efficiency ranging from 40% to 100 % when compared to the OncoDiscover CTC test approved by CDSCO/ drug controller general of India (DCGI). Furthermore, the substrate indicated high biocompatibility primarily exhibited by the absence of haemolysis on whole human blood. Additionally, the preliminary animal experiments in rats showed a 100% survival rate and negligible toxicity to major organs. Conclusions: Removal of circulating tumor cells as a therapeutics is highly implicated in improving the overall survival of epithelial cancer patients. Know more Stay One Step Ahead of Cancer.

  • Association of Circulating Tumor Cell Dynamics with Patient-Reported Cancer Worry in Post-Surgical Breast Cancer Patients

    CTC monitoring in breast cancer detects MRD and supports post-surgery surveillance. Publications | 3 November 2025 Association of Circulating Tumor Cell Dynamics with Patient-Reported Cancer Worry in Post-Surgical Breast Cancer Patients Circulating tumor cell monitoring before and after breast cancer surgery reveals minimal residual disease and correlates with post-surgical cancer worry. Introduction Early detection of metastasis is important for improving overall survival in breast cancer (BC) patients. Circulating tumor cells (CTCs) play a role in detecting minimal residual disease (MRD). In an ongoing cohort, we evaluated the association between CTC dynamics before and after surgery performed with curative intent. Additionally, we assessed cancer-related worry in post-surgical BC patients. Methods A total of 75 CTC tests were performed on 55 female BC patients, of whom 20 were follow-up cases. In an ongoing IEC-approved clinical cohort, 10 BC patients were enrolled using a quantitative, non-probability purposive sampling method. CTC counts, including clusters, were measured both pre-surgery and 24 hours post-surgery. PD-L1 expression on CTCs was assessed using the CDSCO-approved OncoDiscover platform. Patient-reported outcome measures (PROMs) were evaluated using the Breast-Q Cancer Worry scale, a validated subscale reflecting fear of recurrence and related concerns. Statistical analysis compared PROM scores with CTC patterns, including increase, persistence, or clearance. A paired sample t-test was applied to compare pre- and post-operative PROM scores to evaluate changes in cancer-related worry in relation to CTC counts. Results Among the 75 tests performed in 55 BC patients, 84.5% were CTC-positive, with a mean of 1.43 CTCs per test. In longitudinal monitoring of 10 female BC patients who underwent surgery, six received neoadjuvant chemotherapy (NACT) followed by breast-conserving surgery, while four underwent surgery without prior chemotherapy. Overall, 40% (4/10) showed a reduction in CTC counts, and 20% (2/10) achieved complete CTC clearance after surgery. Patients with increased post-surgery CTC counts reported a significant increase in cancer-related worry. The mean pre-surgery score was 43.9, which increased to 51.8 after surgery. These findings suggest the need for targeted emotional and psychological support in the post-surgical period and highlight the role of CTC monitoring in assessing MRD. Conclusions Monitoring CTCs strengthens their potential as an early indicator of residual disease by providing important clinical insights into tumor activity during the operative phase. Further validation is warranted to support more integrated, patient-centered care approaches aimed at reducing the burden of advanced cancer. View Publication Stay One Step Ahead of Cancer.
