abstract = {Fibroblast activation protein (FAP) is highly expressed in
many cancers, especially sarcomas, and represents a
promising theranostic target. We present an updated
retrospective analysis of 90Y-FAP inhibitor (FAPI)-46
treatment in patients with sarcoma or other solid tumors.
Methods: We performed monocentric analysis of patients with
progressive sarcoma or metastatic cancer who were eligible
for 90Y-FAPI-46 therapy after approved treatments had been
exhausted and who showed high FAP expression (SUVmax, ≥10
in over $50\%$ of lesions on 68Ga-FAPI-46 PET). After
therapy, 90Y-FAPI-46 scintigraphy confirmed distribution and
uptake, and serial 90Y-FAPI-46 PET/CT scans measured
absorbed doses. Adverse events were graded by Common
Terminology Criteria for Adverse Events version 5.0. Tumor
responses were evaluated using RECIST and PERCIST. Results:
Thirty patients-23 $(77\%)$ with sarcoma, 3 $(10\%)$ with
pancreatic cancer, 1 $(3\%)$ with prostate cancer, 1 $(3\%)$
with gastric cancer, 1 $(3\%)$ with nonmelanoma skin cancer,
and 1 $(3\%)$ with cholangiocarcinoma-received a total of 77
cycles of 90Y-FAPI-46 radiopharmaceutical therapy between
June 2020 and December 2023 and were followed until death or
the last follow-up (April 2024). The median interval between
cycles was 5 mo (interquartile range [IQR], 4 mo). Of the 30
patients, 11 $(37\%)$ received 4 or more cycles. A median of
3.7 GBq (IQR, 3.7-3.8 GBq) was administered during the first
cycle, and a median of 7.4 GBq (IQR, 7.2-7.4 GBq) was
administered for subsequent cycles. The mean absorbed dose
was 0.48 Gy/GBq (SD, 0.06 Gy/GBq) in the kidneys and 0.04
Gy/GBq (SD, 0.01 Gy/GBq) in the bone marrow. Lesions with
the highest uptake absorbed a mean dose of 2.4 Gy/GBq (SD,
1.04 Gy/GBq). After treatment, hematotoxicity of any grade
was observed in 20 of 30 $(67\%)$ patients. Eight of 30
$(27\%)$ patients reached a Common Terminology Criteria for
Adverse Events grade of at least 3, experiencing adverse
events that included thrombocytopenia in 2 $(6\%),$
neutropenia in 2 $(6\%),$ anemia in 2 $(6\%),$ leukopenia in
1 $(3\%),$ and elevated γ-glutamyl transferase in 1 $(3\%)$
patient. RECIST (n = 25) and PERCIST (n = 20) responses
after treatment were assessed. Disease control according to
RECIST was $48\%$ (12/25), including 3 partial responses
$(12\%).$ Disease control correlated with extended overall
survival (median, 14.6 vs. 1.9 mo). Metabolic response per
PERCIST was observed in 12 of 20 $(60\%)$ patients.
Conclusion: With long-term follow-up, the favorable safety
profile of 90Y-FAPI-46 therapy is confirmed. Nearly half of
the patients demonstrated disease stabilization, almost
exclusively in sarcomas. Our findings support the role of
FAP-directed radiopharmaceutical therapy in patients with
metastatic sarcoma.},
