Abstract

Tumor protein p53 (TP53) is the most frequently mutated gene in cancer 1,2. In patients with myelodysplastic syndromes (MDS), TP53 mutations are associated with high-risk disease 3,4, rapid transformation to acute myeloid leukemia (AML)5, resistance to conventional therapies 6-8 and dismal outcomes 9. Consistent with the tumor-suppressive role of TP53, patients harbor both mono- and biallelic mutations 10. However, the biological and clinical implications of TP53 allelic state have not been fully investigated in MDS or any other cancer type. We analyzed 3,324 patients with MDS for TP53 mutations and allelic imbalances and delineated two subsets of patients with distinct phenotypes and outcomes. One-third of TP53-mutated patients had monoallelic mutations whereas two-thirds had multiple hits (multi-hit) consistent with biallelic targeting. Established associations with complex karyotype, few co-occurring mutations, high-risk presentation and poor outcomes were specific to multi-hit patients only. TP53 multi-hit state predicted risk of death and leukemic transformation independently of the Revised International Prognostic Scoring System (IPSS-R)11. Surprisingly, monoallelic patients did not differ from TP53 wild-type patients in outcomes and response to therapy. This study shows that consideration of TP53 allelic state is critical for diagnostic and prognostic precision in MDS as well as in future correlative studies of treatment response.

  • Treatment outcomes for patients with TP53 mutations are poor with available therapies.

    “Treatment outcomes for patients with TP53 mutations are poor with available therapies.8-12”

    From Eprenetapopt (APR-246) and Azacitidine in <i>TP53</i> -Mutant Myelodysplastic Syndromes (2021) · cites this paper as [9]

    The therapy-response passage (labeled Abstract; no page provided) reports poor responses to lenalidomide and stem-cell transplantation, and transient responses to hypomethylating agents. But the paper’s concluding passage in the same section limits treatment resistance to multi-hit TP53: it says monoallelic patients did not differ from TP53-wild-type patients in response to therapy. The claim overgeneralizes to all patients with TP53 mutations. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • TP53 mutation burden (high variant allele frequency, concurrent complex karyotype, and/or multihit state) is linked to inferior survival with median overall survival of 6-8 months.

    “The TP53 mutation burden (ie, high variant allele frequency [VAF], concurrent complex karyotype, and/or multihit state) is integrally linked to inferior survival with median OS of 6-8 months.8-10,12”

    From Eprenetapopt (APR-246) and Azacitidine in <i>TP53</i> -Mutant Myelodysplastic Syndromes (2021) · cites this paper as [9]

    The paper’s outcomes passage (page unavailable) links multi-hit TP53 and complex karyotype to adverse survival, and its VAF passage reports increased mortality for monoallelic patients with VAF >22%. However, it reports median overall survival of 8.7 months—not 6–8 months—for multi-hit patients, and says multi-hit patients had poor outcomes even at low VAF. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Remissions in TP53-mutant patients are brief, with a median overall survival ranging from 5 to 12 months.

    “However, remissions in TP53-mutant patients are brief with a median overall survival (OS) ranging from 5 to 12 months,8,9,12,13,15-17”

    From Eprenetapopt (APR-246) and Azacitidine in <i>TP53</i> -Mutant Myelodysplastic Syndromes (2021) · cites this paper as [9]

    The paper’s main text reports transient responses to hypomethylating agents and a median overall survival of 8.7 months for patients with multi-hit TP53 MDS. It reports 2.5 years for monoallelic patients, so the stated 5–12-month range does not apply to TP53-mutant patients generally. Page numbers are unavailable in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • TP53 gene mutations (mTP53) represent a distinct molecular cohort with poor outcomes.

    “TP53 gene mutations (mTP53) represent a distinct molecular cohort with poor outcomes.”

    From Long‐term follow‐up and combined Phase 2 results of eprenetapopt and azacitidine in patients with <i>TP53</i> mutant MDS/AML (2025) · cites this paper as [3]

    The Abstract distinguishes TP53-mutant subgroups and reports very poor survival for multi-hit TP53 patients. But it explicitly says that the presence of any TP53 mutation alone does not account for dismal outcomes: monoallelic patients did not differ from TP53 wild-type patients in overall survival. The claim overgeneralizes the poor-outcome finding to all TP53-mutated patients; page numbers were not provided. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • mTP53 is found in up to 20% of MDS/AML and 30-40% of therapy-related MDS/AML cases.

    “TP53 gene mutations (mTP53) are found in up to 20% of myelodysplastic syndromes/neoplasms (MDS) or acute myeloid leukemia (AML) pts and 30%–40% of therapy‐related (TR) MDS/AML cases”

    From Long‐term follow‐up and combined Phase 2 results of eprenetapopt and azacitidine in patients with <i>TP53</i> mutant MDS/AML (2025) · cites this paper as [3]

    The paper reports TP53 mutations in 378 of 3,324 patients with MDS or closely related neoplasms, consistent with the claim’s ‘up to 20%’ figure. But it reports 18% in its therapy-related MDS cases, not 30–40%, and does not establish the claimed prevalence across therapy-related MDS/AML. The decisive passages are labeled Abstract in our copy; no page numbers are available. (LLM, conf=0.86)

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.
