CellularImmunotherapies for thyroid cancer represent a bold leap forward in oncologic and regenerative medicine, offering transformative potential for patients with both differentiated and aggressive thyroid malignancies. Thyroid cancer, a condition that originates in the endocrine tissues of the thyroid gland, ranges in severity from indolent papillary thyroid carcinomas to anaplastic thyroid cancers, which are highly invasive and resistant to conventional therapy. Standard treatments such as thyroidectomy, radioactive iodine ablation, and TSH suppression therapy have significantly improved survival for many—but they fall short in recurrent, metastatic, or iodine-refractory disease. This exploration into cellular immunotherapies unveils a future where precision-targeted cells can track, identify, and destroy malignant thyroid cells, sparing healthy tissue and rejuvenating immune competence.
In the conventional paradigm, thyroid cancer management depends heavily on early surgical intervention and systemic radioactive iodine. However, once the cancer becomes metastatic, dedifferentiates, or develops resistance, the therapeutic options narrow drastically. The introduction of tyrosine kinase inhibitors has extended survival in some advanced cases, but with toxicity and variable response. What these approaches often lack is the ability to re-engineer the immune microenvironment, overcome immune escape mechanisms, and induce durable remissions. Cellular immunotherapy bridges this gap by deploying biologically active, patient-specific or allogeneic immune cells to target tumor-associated antigens (TAAs), reverse immunosuppression, and destroy neoplastic tissue at the molecular level.
The convergence of tumor immunology and regenerative cell science offers an unprecedented opportunity to reimagine the therapeutic landscape for thyroid cancer. Imagine harnessing the innate intelligence of immune cells—natural killer (NK) cells, T-cells, dendritic cells, and tumor-infiltrating lymphocytes (TILs)—to not only fight but adapt and evolve in the face of thyroid malignancy. These cellular agents, engineered or primed to recognize mutated or overexpressed proteins like BRAF V600E, RET/PTC rearrangements, or thyroglobulin peptides, are redefining the immune system’s role in thyroid oncology. At DRSCT, our interdisciplinaryteam of immunologists, endocrinologists, and cellular therapy specialists are forging new pathways where precision meets regeneration [1-5].
2. Genetic Insights: Personalized Immunogenomic Testing Before Cellular Immunotherapies for Thyroid Cancer
Understanding an individual’s genomic and immunogenomic landscape is pivotal in designing effective cellular immunotherapy strategies for thyroid cancer. At DrStemCellsThailand’s Anti-Aging and Regenerative Medicine Center, we offer cutting-edge DNA and immune receptor testing to evaluate each patient’s tumor profile, immune readiness, and risk factors.
Our testing panels encompass crucial somatic mutations including BRAF V600E, RAS mutations (HRAS, NRAS, KRAS), TERT promoter mutations, TP53 aberrations, and RET/PTC and PAX8/PPARγ fusions. These markers not only influence tumor behavior but also serve as direct or indirect targets for adoptive T-cell or NK-cell therapies. Additionally, immune checkpoint profiling (e.g., PD-L1 expression, CTLA-4 status) and HLA typing enable the optimization of autologous or allogeneic immune matching, particularly for CAR-T cell engineering and tumor vaccine development.
Beyond oncogenic mutations, we investigate immunologic SNPs in FOXP3, IL-10, and CTLA-4, which govern immune tolerance, inflammation, and tumor immune escape. Personalized immunogenomic profiling allows us to customize cellular immunotherapies with greater precision, improving patient response and minimizing immune-related adverse events. This comprehensive pre-therapeutic approach ensures a safer, smarter, and more potent engagement with the cancer landscape [1-5].
3. Understanding the Pathogenesis of Thyroid Cancer: A Detailed Overview
Thyroid cancer develops through a sophisticated interplay of genetic mutations, immune evasion, and microenvironmental reprogramming. While the majority of cases are well-differentiated and curable, the subset that progresses to poorly differentiated or anaplastic thyroid cancer poses an immense clinical challenge due to their rapid growth and resistance to traditional therapies.
1. Genetic Mutations and Oncogenic Drivers
BRAF V600E Mutation: Present in over 60% of papillary thyroid cancers, this mutation activates the MAPK pathway, promoting unchecked cell proliferation and reduced iodine uptake.
RET/PTC Rearrangement: Common in radiation-associated thyroid cancers, this fusion protein drives mitogenesis and survival.
TERT Promoter Mutation: Significantly associated with poor prognosis, it upregulates telomerase activity and contributes to aggressive tumor behavior.
TP53 Mutation: Seen in anaplastic thyroid cancers, it disrupts tumor suppression and enhances genomic instability.
2. Tumor Microenvironment and Immune Escape
Immunosuppressive Cell Infiltration: Thyroid tumors often harbor regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), and M2 macrophages that dampen anti-tumor immunity.
Checkpoint Molecule Overexpression: Tumor cells upregulate PD-L1, CTLA-4 ligands, and Galectin-3, facilitating immune evasion by disabling cytotoxic T-cells and NK cells.
Impaired Antigen Presentation: Loss of MHC class I expression on thyroid cancer cells inhibits recognition by cytotoxic T lymphocytes, allowing immune evasion and metastasis.
3. Fibrosis, Angiogenesis, and Metastatic Spread
Fibroblast Activation: Cancer-associated fibroblasts secrete TGF-β and IL-6, which promote tumor progression and resistance to treatment.
Neovascularization: VEGF-driven angiogenesis fuels tumor expansion, while facilitating metastatic dissemination to lungs, bones, and lymph nodes.
Epithelial-Mesenchymal Transition (EMT): A hallmark of aggressive thyroid cancers, EMT allows epithelial cells to acquire mesenchymal characteristics, aiding in invasion and metastasis [1-5].
4. Targeting These Pathways Through Cellular Immunotherapies
Cellular immunotherapies such as CAR-T cells engineered against BRAF-mutant antigens, dendritic cell vaccines loaded with RET/PTC peptides, and NK cell infusions targeting PD-L1+ thyroid cells offer powerful interventions that address these pathogenic pathways head-on. When combined with immune checkpoint blockade, these cell-based strategies can unmask the tumor to the immune system and reestablish immune surveillance.
5. Systemic Complications and Future Prospects
Thyroid Storm Risk: Rare but serious in hyperfunctioning tumors, requiring metabolic stabilization prior to immunotherapy.
Hypothyroidism Post-Therapy: Often a trade-off of effective treatment, requiring long-term hormone replacement.
Thyroid Eye Disease (TED) in Autoimmune Backgrounds: Requires integrated immunologic management when considering immune activation therapies.
The road forward involves multi-pronged strategies—leveraging cell-based therapies, genomic precision, and immune modulation. CellularImmunotherapies for thyroid cancer not only offer the potential for remission and cure but open a new chapter in endocrine oncology, where the immune system becomes the most powerful ally against thyroid malignancies [1-5].
4. Underlying Causes of Thyroid Cancer: Navigating the Intricate Triggers of Tumorigenesis
Thyroid cancer, a malignancy arising from follicular or parafollicular cells within the thyroid gland, is characterized by complex etiological mechanisms that integrate genetic mutations, immune dysfunction, environmental exposures, and aberrant signaling cascades. The progression from a benign thyroid nodule to invasive cancer reflects a multistep process influenced by several converging factors:
Oncogenic Mutations and Genetic Susceptibility
Somatic mutations in key oncogenes such as BRAF (particularly V600E), RET/PTC rearrangements, RAS mutations, and TERT promoter mutations contribute directly to thyroid tumorigenesis, especially in papillary and poorly differentiated subtypes. These mutations deregulate MAPK and PI3K/AKT pathways, leading to uncontrolled cellular proliferation, resistance to apoptosis, and genomic instability.
Familial syndromes such as Cowden’s disease and familial medullary thyroid carcinoma (MTC) also underscore the role of inherited gene alterations like PTEN and RET proto-oncogene mutations in cancer predisposition.
Immune Evasion and Tumor Microenvironment Remodeling
As thyroid tumors evolve, they acquire the capacity to escape immune surveillance through multiple mechanisms:
Overexpression of immune checkpoint molecules like PD-L1 on tumor cells leads to functional exhaustion of cytotoxic T lymphocytes.
Recruitment of regulatory T cells (Tregs), tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs) suppresses effective anti-tumor immune responses.
Cytokine secretion (TGF-β, IL-10) and chemokine dysregulation remodel the thyroid tumor microenvironment into an immunosuppressive niche that supports tumor survival.
Hormonal and Environmental Influences
Thyroid-stimulating hormone (TSH), when chronically elevated, can drive follicular cell proliferation and neoplastic transformation. Iodine deficiency or excess has also been implicated in increased thyroid cancer risk.
Ionizing radiation exposure, particularly during childhood, represents one of the most well-established environmental risk factors, triggering DNA double-strand breaks that precipitate chromosomal rearrangements and malignant transformation. [6-10].
Epigenetic and Metabolic Reprogramming
Aberrant DNA methylation, histone modifications, and dysregulation of non-coding RNAs contribute to silencing of tumor suppressor genes and activation of oncogenes. Additionally, thyroid cancer cells often undergo metabolic reprogramming, favoring glycolysis (Warburg effect) and altered mitochondrial respiration to support rapid growth and immune resistance.
Tumor Heterogeneity and Clonal Evolution
In advanced or treatment-resistant thyroid cancers, clonal evolution drives intratumoral heterogeneity. Subclones acquire differential mutations and immune evasion strategies, making them more resistant to standard therapies and necessitating novel personalized approaches like cellular immunotherapy.
Given these multifaceted drivers of thyroid cancer, an immunologically targeted, regenerative, and individualized therapeutic model is essential to disrupt its progression and improve patient outcomes [6-10].
5. Challenges in Conventional Therapies for Thyroid Cancer: Immunological Resistance and Clinical Limitations
Traditional treatment options for thyroid cancer, such as thyroidectomy, radioactive iodine (RAI) ablation, external beam radiation, and kinase inhibitors, offer moderate success, particularly in early stages. However, significant therapeutic barriers persist:
Radioiodine-Refractory Disease
A subset of patients with differentiated thyroid cancer (DTC) lose the ability to uptake iodine due to dedifferentiation, rendering RAI therapy ineffective. These patients face higher recurrence and metastatic risk without viable curative alternatives.
Drug Resistance in Advanced Thyroid Cancer
Multikinase inhibitors (MKIs) like sorafenib and lenvatinib offer transient tumor control but frequently encounter resistance due to secondary mutations in RET, BRAF, or downstream PI3K/AKT pathway components. Adverse effects such as hypertension, fatigue, and hepatotoxicity further limit long-term utility.
Ineffectiveness in Immune-Resistant Tumors
Traditional therapies do not correct immune dysregulation or reprogram the immunosuppressive tumor microenvironment. This is especially problematic in poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid carcinoma (ATC), where aggressive behavior and immune evasion are hallmarks.
Recurrence and Metastatic Burden
Up to 30% of patients with thyroid cancer experience recurrence, and distant metastases to lungs, bones, or brain often evade control by surgery and RAI. The inability of conventional therapies to induce long-term systemic anti-tumor immunity contributes to disease persistence.
These clinical hurdles underscore the urgency for precision CellularImmunotherapies for thyroid cancer capable of restoring anti-tumor immune function, targeting resistant clones, and preventing recurrence at the systemic level [6-10].
6. Breakthroughs in Cellular Immunotherapy for Thyroid Cancer: Immune Reprogramming and Tumor Elimination
Revolutionary strides in cellular immunotherapies are transforming thyroid cancer treatment paradigms, particularly for advanced, metastatic, or refractory cases. Key milestones include:
Autologous T Cell Therapy with Immune Checkpoint Blockade

Year: 2020 Researcher: Dr. Hyam Levitsky Institution: Johns Hopkins University, USA Result: CAR-T cells engineered to target GDNF-family receptor alpha 4 (GFRα4), a MTC-associated antigen, selectively eradicated tumor cells in preclinical models without damaging healthy thyroid tissue. Phase I trials demonstrated preliminary safety and tumor-specific efficacy.
Dendritic Cell (DC) Vaccines Loaded with Tumor Lysate
Year: 2021 Researcher: Dr. Erika Hamilton Institution: Sarah Cannon Research Institute, USA Result: Personalized dendritic cell vaccines pulsed with autologous tumor lysates induced robust Th1 responses and increased CD8+ cytotoxic lymphocytes in patients with metastatic DTC. Clinical benefit was observed in 40% of participants [6-10].
Natural Killer (NK) Cell Immunotherapy with Interleukin-15 (IL-15)
Year: 2022 Researcher: Dr. Koji Tamada Institution: Yamaguchi University, Japan Result: IL-15–primed NK cells showed enhanced migration, tumor cytolysis, and cytokine secretion against BRAF-mutant thyroid carcinoma cells. Adoptive transfer of these NK cells led to substantial tumor burden reduction in preclinical xenografts.
Tumor-Infiltrating Lymphocyte (TIL) Expansion Protocols for Anaplastic Thyroid Cancer
Year: 2023 Researcher: Dr. Stephanie Goff Institution: NIH Clinical Center, USA Result: Rapid expansion protocols for autologous TILs extracted from ATC tissues enabled successful reinfusion into patients, resulting in partial responses and increased survival. Genetic profiling revealed enrichment of neoantigen-reactive T cell clones.
These CellularImmunotherapies for thyroid cancer, tailored to individual tumor immunophenotypes and genomic profiles, are redefining the standard of care for thyroid cancer, particularly for those resistant to conventional treatments [6-10].
7. Public Advocates and Voices Supporting Cellular Immunotherapies for Thyroid Cancer
Thyroid cancer, while often treatable in early stages, has gained public attention due to its rising incidence and the challenges posed by advanced disease. Several public figures have helped bring awareness to the need for cutting-edge therapies, including cellular immunotherapy:
Sofia Vergara: The actress and entrepreneur was diagnosed with thyroid cancer at 28 and has since advocated for cancer screening and personalized medicine.
Brooke Burke: The TV host underwent thyroidectomy after being diagnosed with papillary thyroid cancer and now supports patient-centered treatment options and research.
Catherine Bell: Known for her roles in military dramas, she has publicly discussed her thyroid cancer journey and promoted integrative cancer therapies.
Rod Stewart’s Daughter, Kimberly Stewart: Shared her father’s thyroid nodule scare, leading to broader discussion of thyroid screening and early immune-based interventions.
These influential voices contribute to the growing momentum for exploring next-generation treatments like CellularImmunotherapies for thyroid cancer, encouraging global attention and funding toward regenerative cancer immunology [6-10].
8. Cellular Players in Thyroid Cancer: Unraveling Tumor Immunobiology
Thyroid cancer, particularly aggressive forms such as anaplastic thyroid carcinoma (ATC) and poorly differentiated thyroid carcinoma (PDTC), is driven by a complex interplay of malignant transformation and immune evasion. Cellular Immunotherapies for Thyroid Cancer aim to correct the immunological dysfunction by restoring tumor surveillance and inducing immune-mediated cytotoxicity.
Thyroid Epithelial Tumor Cells: These are the transformed follicular cells that harbor mutations (BRAF, RAS, RET/PTC) and exhibit resistance to apoptosis, uncontrolled proliferation, and immune escape via PD-L1 overexpression.
Tumor-Associated Macrophages (TAMs): Often polarized to an M2-like phenotype, TAMs promote tumor angiogenesis, suppress adaptive immunity, and facilitate thyroid cancer invasion and metastasis.
Cancer-Associated Fibroblasts (CAFs): These stromal cells secrete immunosuppressive cytokines like TGF-β, which contribute to T-cell exhaustion and immune checkpoint upregulation.
Dendritic Cells (DCs): In thyroid tumors, DCs exhibit dysfunctional antigen presentation and promote immune tolerance rather than cytotoxicity.
Cytotoxic T Lymphocytes (CTLs): Infiltrating CTLs are rendered ineffective by high PD-1 expression and TME-induced exhaustion, a key target of checkpoint inhibitors.
Natural Killer (NK) Cells: NK cell function is impaired in aggressive thyroid cancers, with reduced cytolytic granules and disrupted MICA/B-NKG2D signaling pathways.
Regulatory T Cells (Tregs): Expanded in the thyroid tumor microenvironment, Tregs suppress anti-tumor immunity by secreting IL-10 and TGF-β, enhancing immune escape.
Mesenchymal Stem Cells (MSCs): Engineered MSCs and tumor-infiltrating MSCs are double-edged: while native MSCs might support tumor growth, engineered MSCs serve as vehicles for immunostimulatory or oncolytic therapies.
By dissecting these cellular dysfunctions, CellularImmunotherapies for thyroid cancer aim to rejuvenate immune responses and dismantle the immunosuppressive shield around the tumor [11-13].

By targeting the immunologic vulnerabilities of thyroid cancer, our CellularImmunotherapies for thyroid cancer Program provides a highly specialized and revolutionary approach to managing the disease before it reaches advanced or metastatic stages [14-17].
16. Timing Matters: Early Cellular Immunotherapies for Thyroid Cancer for Maximum Anti-Tumor Benefit
Our oncology and immunotherapy teams stress the critical value of early immune intervention in managing thyroid cancer—especially aggressive forms like poorly differentiated and anaplastic thyroid carcinoma.
Early TIL or CAR-T administration in patients with limited metastatic burden leads to better tumor regression, reduced mutational escape, and greater long-term immunologic memory.
Checkpoint Inhibitor-Primed Cell Therapies, introduced at the initial onset of immune resistance, enhance antigen presentation and rejuvenate exhausted T cells, improving tumor clearance rates.
Patients receiving early NK or dendritic cell therapy show greater modulation of the tumor microenvironment, improved response to radioactive iodine, and reduced tumor marker levels.
Initiating immunotherapy in the early stages of thyroid malignancy provides a distinct survival advantage and reduces the likelihood of aggressive progression [14-17].
17. Mechanistic Excellence: How Cellular Immunotherapies Work in Thyroid Cancer
Thyroid cancer often creates an immune-suppressive microenvironment that evades traditional treatments. Our cellular immunotherapy platform works through multiple precise and coordinated mechanisms:
1. Direct Cytotoxicity and Tumor Cell Clearance
CAR-T and NK cells recognize and destroy thyroid tumor cells via granzyme-perforin pathways, disrupting tumor architecture and inducing apoptosis.
2. Tumor Microenvironment Reprogramming
Engineered immune cells secrete interferon-gamma and other pro-inflammatory cytokines to neutralize immunosuppressive factors like TGF-β and VEGF, restoring immune surveillance.
3. Antigen-Specific Recognition
CAR-T cells are designed to detect thyroid tumor-specific antigens (e.g., TG, NIS, TROP-2), ensuring precise targeting while minimizing off-tumor toxicity.
4. Overcoming Iodine-Refractoriness
NK cells enhance sodium-iodide symporter (NIS) function, making tumors more responsive to radioactive iodine even in dedifferentiated disease.
5. Stimulation of Endogenous Immune Memory
Dendritic cell vaccines prime cytotoxic T lymphocytes, facilitating durable immunologic memory against recurring cancer clones.
These cellular immune mechanisms represent the most innovative and adaptive tools in our arsenal against thyroid cancer [14-17].
18. Understanding Thyroid Cancer: Five Stages of Cellular Immunotherapy Application
Thyroid cancer evolves through clinical and molecular stages that correspond to specific immune vulnerabilities. Our program customizes cellular interventions accordingly:
Stage 1: Localized Differentiated Thyroid Cancer
Disease Profile: Papillary or follicular carcinoma, localized to thyroid gland.

Stage 3: Iodine-Refractory or Aggressive Variant
Disease Profile: Poorly differentiated thyroid cancer resistant to radioactive iodine.
Standard Care: Limited efficacy with kinase inhibitors.
Cellular Immunotherapy Role: NK cells restore iodine sensitivity and target resistant clones; CAR-T eliminates non-differentiated subpopulations.
Stage 4: Distant Metastasis
Disease Profile: Pulmonary, skeletal, or hepatic metastases.
Standard Care: TKIs with declining durability.
Cellular Immunotherapy Role: Adoptive transfer of engineered T cells offers systemic anti-tumor immunity and mitigates metastatic burden.
Stage 5: Anaplastic Thyroid Carcinoma (ATC)
Disease Profile: Rapidly progressing, undifferentiated malignancy with high mortality.
Standard Care: Limited response to chemotherapy or radiation.
Patient-Tailored Cell Engineering: Custom CAR constructs targeting unique patient-specific antigens for superior selectivity.
Multi-Modal Delivery Approaches: Intravenous infusion, direct intratumoral injection, and lymphatic-targeted delivery ensure precise localization.
Durable Remission Protocols: Long-acting T cell memory formation combined with checkpoint inhibitor modulation for persistent protection.
This approach empowers the immune system to transform from passive observer into active defender—offering patients a new future without chronic recurrence or systemic toxicity [14-17].

Umbilical Cord-Derived Mesenchymal Stem Cells (UC-MSCs): These highly proliferative cells not only support immune modulation but also create a tumor-suppressive microenvironment by inhibiting angiogenesis and interfering with tumor cell signaling in papillary and anaplastic thyroid cancers.
Wharton’s Jelly Mesenchymal Stem Cells (WJ-MSCs): With superior immunosuppressive and anti-inflammatory properties, WJ-MSCs serve as ideal carriers for gene-modified immunotherapies. Engineered WJ-MSCs can secrete therapeutic cytokines such as IL-12 and IFN-γ, boosting anti-tumor immune responses and inducing apoptosis in malignant thyroid cells.
Placental-Derived Stem Cells (PLSCs): These cells express key immunoregulatory markers and release high levels of exosomes rich in microRNAs targeting tumor growth and metastasis, making them ideal for aggressive variants such as medullary thyroid carcinoma.
Amniotic Fluid Stem Cells (AFSCs): With multipotent differentiation potential, AFSCs assist in restoring thyroid tissue architecture post-ablation and secrete growth factors that inhibit cancer-associated fibroblasts, reducing tumor stroma support.
Cytotoxic T Lymphocytes (CTLs): Engineered from allogeneic sources, CTLs specifically recognize and kill thyroid tumor cells expressing aberrant markers such as BRAF V600E or RET/PTC rearrangements.
Natural Killer (NK) Cells: Expanded and activated NK cells demonstrate potent cytotoxic effects against iodine-refractory thyroid cancer by targeting NKG2D ligands and overcoming tumor-induced immune evasion.
This comprehensive arsenal of stem and immune cells is tailored to disrupt thyroid cancer progression at multiple levels—immune suppression, tumor signaling, angiogenesis, and metastatic spread—while minimizing the risk of rejection or adverse reactions [18-21].

Hormonal Status: Thyroid function panels and evidence of hormone replacement therapy stabilization.
Stability Reports: Clinical records verifying no acute cardiovascular or renal complications in the past 3 months.
Candidates who meet these comprehensive benchmarks may benefit from our advanced immunotherapy protocols, potentially slowing cancer progression and improving prognosis [18-21].
27. Qualification Protocol for International Patients Seeking Cellular Immunotherapy for Thyroid Cancer
International patients must undergo an exhaustive pre-treatment qualification process to ensure compatibility with our CellularImmunotherapies for thyroid cancer program. The protocol includes:
Recent Imaging Studies: Thyroid ultrasound, neck CT/MRI, and full-body PET scans to assess staging.
Genetic Panels: BRAF V600E, TERT promoter, RET/PTC, and NTRK fusion testing to guide targeted immunotherapy.
Medical History Review: Prior treatments (surgery, RAI, TKI), hormone therapy compliance, and any immunosuppressive drug usage.
Candidates passing this review will be scheduled for a personalized consultation and therapy plan [18-21].
28. Personalized Consultation and Treatment Blueprint for Thyroid Cancer Immunotherapy
Following patient acceptance, a dedicated team of oncologists and immunologists formulates a personalizedimmunotherapy plan. This includes:
Therapy Details: Administration of 20–80 million activated NK or CTL cells, often combined with UC–MSC or WJ-MSC co-therapy to enhance immune activity and tumor suppression.
Administration Routes: Intra-lesional for localized tumors, intravenous for systemic metastasis, or intra-arterial in select high-burden cases.
Supportive Therapies:Exosome infusions, low-dose IL-2, immune checkpoint inhibitors, or metabolic reprogramming to enhance immune activation.
Duration and Schedule: Typical treatment spans 10–14 days in Thailand, with multiple infusions, real-time immune monitoring, and post-therapy evaluations.
Patients receive a detailed cost estimate, excluding travel expenses, based on their clinical complexity and adjunctive treatments [18-21].
29. Integrated Therapy Regimen for International Patients Undergoing Immunotherapy for Thyroid Cancer
Once approved, patients undergo a regimented treatment cycle designed to elicit a sustained anti-tumor response:
Cellular Immunotherapy Protocol:
NK Cell Infusions (50–80 million cells): For broad cytotoxicity across all thyroid cancer subtypes.
CTLs or CAR-T Cells (20–40 million cells): If available, genetically engineered for mutation-specific targeting.
