Abstract

Purpose: There are few treatment options for patients with metastasized or inoperable endocrine gastroenteropancreatic (GEP) tumors. Chemotherapy can be effective, but the response is usually less than 1 year. Here, we present the results of treatment with a radiolabeled somatostatin analog, [177 Lu-DOTA 0,Tyr 3]octreotate (177 Lu-octreotate). Patients and Methods: One hundred thirty-one patients with somatostatin receptor-positive tumors were treated with up to a cumulative dose of 600 to 800 mCi (22.2 to 29.6 GBq) of 177 Lu-octreotate. Results: One patient developed renal insufficiency, and another patient developed hepatorenal syndrome. Creatinine clearance did not change significantly in the other patients. WHO hematologic toxicity grade 3 or 4 occurred after less than 2% of the administrations. We observed complete remission in three patients (2%), partial remission in 32 patients (26%), minor response (tumor diameter decrease of 25% to 50%) in 24 patients (19%), stable disease (SD) in 44 patients (35%), and progressive disease (PD) in 22 patients (18%). Higher remission rates were positively correlated with high uptake on pretherapy somatostatin receptor imaging and a limited number of liver metastases, whereas PD was significantly more frequent in patients with a low performance score and extensive disease. Median time to progression in 103 patients who either had SD or tumor regression was more than 36 months. Conclusion: Treatment with 177 Lu-octreotate results in tumor remission in a high percentage of patients with GEP tumors. Serious side effects are rare. The median time to progression compares favorably with chemotherapy. Results are better in patients with a limited tumor load. Therefore, early treatment, even in patients who have no PD, may be better.

  • With adoption of amino acid pretreatment, the incidence of serious toxicity has been low, at or below 1.5% grade III or IV CTCAE, regardless of treatment schedule, number of cycles, and administered activity per cycle or cumulatively.

    “In fact, with the adoption of amino acid pretreatment, the incidence of serious toxicity has been low, # 1.5% grade III or IV CTCAE, regardless of the treatment schedule, the number of cycles and administered activity per cycle or cumulatively ( 65 , 66 ).”

    From Normal-Tissue Tolerance to Radiopharmaceutical Therapies, the Knowns and the Unknowns (2021) · cites this paper as [66]

    The Methods describe amino-acid infusion before treatment, and the Results report low rates of severe hematologic toxicity. However, the paper uses WHO rather than CTCAE grades; grade 3 and 4 thrombocytopenia occurred after 1.5% and 0.2% of administrations, respectively, exceeding 1.5% when combined. It does not establish that toxicity was low regardless of schedule, cycle count, or administered activity. Page numbers were not provided in our copy. (LLM, conf=0.89)

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.
