Abstract

Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor originating from the parafollicular cells. The diagnostic and therapeutic strategies for the condition are different from those used for well-differentiated thyroid cancer. Since the 2015 American Thyroid Association guidelines for the diagnosis and treatment of MTC, the latest, including the National Comprehensive Cancer Network and European Association for Medical Oncology guidelines have been updated to reflect several recent advances in the management of MTC. Advances in molecular diagnosis and postoperative risk stratification systems have led to individualized treatment and follow-up strategies. Multi-kinase inhibitors, such as vandetanib and cabozantinib, can prolong disease progression-free survival with favorable adverse effects. In addition, potent selective rearranged during transfection (RET) inhibitors (selpercatinib and pralsetinib) have shown a promising efficacy in recent clinical trials. This review summarizes the management of MTC in recent guidelines focused on sporadic MTC.

  • The most commonly used photosensitizers in PDT for thyroid cancers include hypericin, porphyrin, photophrin, radachlorin, and 5-aminolevulinic acid (ALA).

    “The most commonly used PS in PDT for the treatment of thyroid cancers include hypericin, porphyrin, photophrin, radachlorin, and 5-aminolevulinic acid (ALA). [8-10,14,32]”

    From Photodynamic Therapy for Thyroid Cancer (2025) · cites this paper as [32]

    The 'Management in Persistent or Recurrent MTC' section discusses radionuclide therapy and other treatments, but does not address photodynamic therapy or photosensitizers. Searches for PDT, photosensitizers, and the named compounds found no passage supporting the claimed list or its frequency of use. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Treatment of the cell line with PDT using photophrin at 0.8 and 1.6 mg/ml reduced cell viability, to a greater extent at higher photophrin concentrations.

    “Treatment of the cell line with PDT using photophrin at concentrations of 0.8 and 1.6 mg/ml reduced cell viability, to a greater extent at higher photophrin concentrations.”

    From Photodynamic Therapy for Thyroid Cancer (2025) · cites this paper as [32]

    The section on management of persistent or recurrent medullary thyroid carcinoma discusses drug therapy and radionuclide therapy, but not photodynamic therapy in a cell line. Searches for photophrin, the 0.8 and 1.6 mg/ml concentrations, and cell viability found no passage addressing the claimed result; page numbers were not available in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • The changes were particularly marked in higher concentrations of the photosensitizer or in combination with sulforaphene, carboplatin, or genistein.

    “The changes were particularly marked in higher concentrations of the photosensitizer or in combination with sulforaphene, carboplatin, or genistein.”

    From Photodynamic Therapy for Thyroid Cancer (2025) · cites this paper as [32]

    The Management in Persistent or Recurrent MTC section discusses kinase inhibitors, chemotherapy, and radionuclide therapy, but not changes at higher photosensitizer concentrations or combinations with sulforaphene, carboplatin, or genistein. Searches for those substances and for photodynamic therapy found no passage addressing the claim; page numbers were unavailable in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • In combined therapy compared to individual therapies, after 6 h, a greater number of apoptotic cells, covering almost all cells, was observed.

    “a greater number of apoptotic cells, covering almost all cells”

    From Photodynamic Therapy for Thyroid Cancer (2025) · cites this paper as [32]

    The Management in Persistent or Recurrent MTC section discusses treatment regimens and clinical outcomes, but not apoptotic-cell counts after six hours. Searches for the quoted apoptotic-cell observation and for six-hour combination-therapy results found no passage addressing the claim in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • Treatment of cells with genistein alone, regardless of time interval (3, 6, 24 h) and concentration (25, 50, 100 mM), did not result in changes in cell viability.

    “It was shown that treatment of cells with genistein, regardless of the time interval (3, 6 and 24 h) and concentration (25, 50, 100 mM) did not result in changes in cell viability.”

    From Photodynamic Therapy for Thyroid Cancer (2025) · cites this paper as [32]

    The cited paper’s ‘Management in Persistent or Recurrent MTC’ section discusses clinical treatments, including vandetanib and cabozantinib, rather than genistein-treated cells. Searches of our full-text copy for genistein, cell viability, and the stated treatment times and concentrations found no passage addressing the claim. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
