Association of Upfront Peptide Receptor Radionuclide Therapy With Progression-Free Survival Among Patients With Enteropancreatic Neuroendocrine Tumors
open57noIMPORTANCE Data about the optimal timing for the initiation of peptide receptor radionuclide
therapy (PRRT) for advanced, well-differentiated enteropancreatic neuroendocrine tumors
are lacking.
OBJECTIVE To evaluate the association of upfront PRRT vs upfront chemotherapy or targeted
therapy with progression-free survival (PFS) among patients with advanced enteropancreatic
neuroendocrine tumors who experienced disease progression after treatment with somatostatin
analogues (SSAs).
DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study analyzed the
clinical records from 25 Italian oncology centers for patients aged 18 years or older who had
unresectable, locally advanced or metastatic, well-differentiated, grades 1 to 3 enteropancreatic
neuroendocrine tumors and received either PRRT or chemotherapy or targeted therapy after
experiencing disease progression after treatment with SSAs between January 24, 2000, and July 1,
2020. Propensity score matching was done to minimize the selection bias.
EXPOSURES Upfront PRRT or upfront chemotherapy or targeted therapy.
MAIN OUTCOMES AND MEASURES The main outcome was the difference in PFS among patients
who received upfront PRRT vs among those who received upfront chemotherapy or targeted
therapy. A secondary outcome was the difference in overall survival between these groups. Hazard
ratios (HRs) were fitted in a multivariable Cox proportional hazards regression model to adjust for
relevant factors associated with PFS and were corrected for interaction with these factors.
RESULTS Of 508 evaluated patients (mean ([SD] age, 55.7 [0.5] years; 278 [54.7%] were male), 329
(64.8%) received upfront PRRT and 179 (35.2%) received upfront chemotherapy or targeted
therapy. The matched group included 222 patients (124 [55.9%] male; mean [SD] age, 56.1 [0.8]
years), with 111 in each treatment group. Median PFS was longer in the PRRT group than in the
chemotherapy or targeted therapy group in the unmatched (2.5 years [95%CI, 2.3-3.0 years] vs 0.7
years [95%CI, 0.5-1.0 years]; HR, 0.35 [95%CI, 0.28-0.44; P < .001]) and matched (2.2 years [95%
CI, 1.8-2.8 years] vs 0.6 years [95%CI, 0.4-1.0 years]; HR, 0.37 [95%CI, 0.27-0.51; P < .001])
populations. No significant differences were shown in median overall survival between the PRRT and chemotherapy or targeted therapy groups in the unmatched (12.0 years [95%CI, 10.7-14.1 years] vs
11.6 years [95%CI, 9.1-13.4 years]; HR, 0.81 [95%CI, 0.62-1.06; P = .11]) and matched (12.2 years [95%
CI, 9.1-14.2 years] vs 11.5 years [95%CI, 9.2-17.9 years]; HR, 0.83 [95%CI, 0.56-1.24; P = .36])
populations. The use of upfront PRRT was independently associated with improved PFS (HR, 0.37;
95%CI, 0.26-0.51; P < .001) in multivariable analysis. After adjustment of values for interaction,
upfront PRRT was associated with longer PFS regardless of tumor functional status (functioning:
adjusted HR [aHR], 0.39 [95%CI, 0.27-0.57]; nonfunctioning: aHR, 0.29 [95%CI, 0.16-0.56]), grade
of 1 to 2 (grade 1: aHR, 0.21 [95%CI, 0.12-0.34]; grade 2: aHR, 0.52 [95%CI, 0.29-0.73]), and site of
tumor origin (pancreatic: aHR, 0.41 [95%CI, 0.24-0.61]; intestinal: aHR, 0.19 [95%CI, 0.11-0.43])
(P < .001 for all). Conversely, the advantage was not retained in grade 3 tumors (aHR, 0.31; 95%CI,
0.12-1.37; P = .13) or in tumors with a Ki-67 proliferation index greater than 10% (aHR, 0.73; 95%CI,
0.29-1.43; P = .31).
CONCLUSIONS AND RELEVANCE In this cohort study, treatment with upfront PRRT in patients
with enteropancreatic neuroendocrine tumors who had experienced disease progression with SSA
treatment was associated with significantly improved survival outcomes compared with upfront
chemotherapy or targeted therapy. Further research is needed to investigate the correct strategy,
timing, and optimal specific sequence of these therapeutic options.openPusceddu, Sara; Prinzi, Natalie; Tafuto, Salvatore; Ibrahim, Toni; Filice, Angelina; Brizzi, Maria Pia; Panzuto, Francesco; Baldari, Sergio; Grana, Chiara M.; Campana, Davide; Davì, Maria Vittoria; Giuffrida, Dario; Zatelli, Maria Chiara; Partelli, Stefano; Razzore, Paola; Marconcini, Riccardo; Massironi, Sara; Gelsomino, Fabio; Faggiano, Antongiulio; Giannetta, Elisa; Bajetta, Emilio; Grimaldi, Franco; Cives, Mauro; Cirillo, Fernando; Perfetti, Vittorio; Corti, Francesca; Ricci, Claudio; Giacomelli, Luca; Porcu, Luca; Di Maio, Massimo; Seregni, Ettore; Maccauro, Marco; Lastoria, Secondo; Bongiovanni, Alberto; Versari, Annibale; Persano, Irene; Rinzivillo, Maria; Pignata, Salvatore Antonio; Rocca, Paola Anna; Lamberti, Giuseppe; Cingarlini, Sara; Puliafito, Ivana; Ambrosio, Maria Rosaria; Zanata, Isabella; Bracigliano, Alessandra; Severi, Stefano; Spada, Francesca; Andreasi, Valentina; Modica, Roberta; Scalorbi, Federica; Milione, Massimo; Sabella, Giovanna; Coppa, Jorgelina; Casadei, Riccardo; Di Bartolomeo, Maria; Falconi, Massimo; de Braud, FilippoPusceddu, Sara; Prinzi, Natalie; Tafuto, Salvatore; Ibrahim, Toni; Filice, Angelina; Brizzi, Maria Pia; Panzuto, Francesco; Baldari, Sergio; Grana, Chiara M.; Campana, Davide; Davì, Maria Vittoria; Giuffrida, Dario; Zatelli, Maria Chiara; Partelli, Stefano; Razzore, Paola; Marconcini, Riccardo; Massironi, Sara; Gelsomino, Fabio; Faggiano, Antongiulio; Giannetta, Elisa; Bajetta, Emilio; Grimaldi, Franco; Cives, Mauro; Cirillo, Fernando; Perfetti, Vittorio; Corti, Francesca; Ricci, Claudio; Giacomelli, Luca; Porcu, Luca; Di Maio, Massimo; Seregni, Ettore; Maccauro, Marco; Lastoria, Secondo; Bongiovanni, Alberto; Versari, Annibale; Persano, Irene; Rinzivillo, Maria; Pignata, Salvatore Antonio; Rocca, Paola Anna; Lamberti, Giuseppe; Cingarlini, Sara; Puliafito, Ivana; Ambrosio, Maria Rosaria; Zanata, Isabella; Bracigliano, Alessandra; Severi, Stefano; Spada, Francesca; Andreasi, Valentina; Modica, Roberta; Scalorbi, Federica; Milione, Massimo; Sabella, Giovanna; Coppa, Jorgelina; Casadei, Riccardo; Di Bartolomeo, Maria; Falconi, Massimo; de Braud, Filipp
Multidisciplinary approach including receptor radionuclide therapy with90Y-DOTATOC ([90Y-DOTA0,Tyr3]- octreotide) and177Lu-DOTATATE ([177Lu-DOTA0,Tyr3]-octreotate) in ectopic Cushing syndrome from a metastatic gastrinoma: A promising proposal
Objective: To present a case of a young woman with Cushing syndrome caused by ectopic production of adrenocorticotropic hormone from a metastatic pancreatic gastrin-secreting endocrine carcinoma, who had a good response to combination peptide receptor radionuclide therapy. Methods: We review the history, physical examination, laboratory investigations, and radiographic findings in this unusual patient. Moreover, the multimodal interventions are described and discussed. Results: In a 38-year-old woman with typical signs of cortisol excess, laboratory studies revealed diabetes mellitus, hypokalemia, and high levels of adrenocorticotropic hormone, plasma cortisol, and urinary cortisol. Abdominal computed tomography showed a 4-cm pancreatic mass and multiple metastatic lesions in the liver, and ectopic Cushing syndrome was diagnosed. Treatment consisted of surgical debulking of the tumor, ketoconazole, somatostatin analogues, chemoembolization of the liver metastatic lesions, and peptide receptor radionuclide therapy with the radiolabeled somatostatin analogues90Y-DOTATOC ([90Y-DOTA0,Tyr3]-octreotide) and177Lu-DOTATATE ([177Lu- DOTA0,Tyr3]-octreotate). The 5 1/2-year follow-up showed positive results, which included complete regression of all clinical and hormonal evidence of the tumor and substantial decrease in the size and number of hepatic metastatic lesions. The patient achieved and still maintains an optimal quality of life. Conclusion: To the best of our knowledge, this is the first report of a multidisciplinary approach including peptide receptor radionuclide therapy with90Y-DOTATOC and177Lu-DOTATATE, which proved to be effective in improving clinical outcome in a case of metastatic endocrine carcinoma of the pancreas in conjunction with ectopic Cushing syndrome. In this unusual case, the patient has one of the longest durations of survival in this setting described in the literature. © 2008 AACE

Metformin Use Is Associated With Longer Progression-Free Survival of Patients With Diabetes and Pancreatic Neuroendocrine Tumors Receiving Everolimus and/or Somatostatin Analogues
Background & Aims: Metformin seems to have anticancer effects. However, it is not clear whether use of glycemia and metformin affect outcomes of patients with advanced pancreatic neuroendocrine tumors (pNETs). We investigated the association between glycemia and progression-free survival (PFS) of patients with pNETs treated with everolimus and/or somatostatin analogues, as well as the association between metformin use and PFS time. Methods: We performed a retrospective analysis of 445 patients with advanced pNET treated at 24 medical centers in Italy from 1999 through 2015. Data on levels of glycemia were collected at time of diagnosis of pNET, before treatment initiation, and during treatment with everolimus (with or without somatostatin analogues), octreotide, or lanreotide. Diabetes was defined as prior or current use of glycemia control medication and/or fasting plasma glucose level ≥ 126 mg/dL, hemoglobin A1c ≥ 6.5% (48 mmol/L), or a random sample of plasma glucose ≥ 200 mg/dL (11.1 mmol/L), with reported classic symptoms of hyperglycemia or hyperglycemic crisis. Patients were assigned to groups based on diagnosis of diabetes before or during antitumor therapy. PFS was compared between patients with vs without diabetes. Among patients with diabetes, the association between metformin use and PFS was assessed. We performed sensitivity and landmark analyses to exclude patients who developed diabetes while receiving cancer treatment and to exclude a potential immortal time bias related to metformin intake. Results: PFS was significantly longer in patients with diabetes (median, 32.0 months) than without diabetes (median, 15.1 months) (hazard ratio for patients with vs without diabetes, 0.63; 95% confidence interval, 0.50–0.80; P =.0002). PFS of patients treated with metformin was significantly longer (median PFS, 44.2 months) than for patients without diabetes (hazard ratio for survival of patients with diabetes receiving metformin vs without diabetes, 0.45; 95% confidence interval, 0.32–0.62; P <.00001) and longer than for patients with diabetes receiving other treatments (median PFS, 20.8 months; hazard ratio, 0.49; 95% confidence interval, 0.34–0.69; P <.0001). In multivariable analysis, adjusted for other factors associated with outcomes, metformin was associated with longer PFS but level of glycemia was not. Metformin was associated with increased PFS of patients receiving somatostatin analogues and in those receiving everolimus, with or without somatostatin analogues. Sensitivity and landmark analyses produced similar results. Conclusions: In a retrospective study of patients with pNETs, we found a significant association between metformin use and longer PFS
Appropriateness of antiplatelet therapy for primary and secondary cardio- and cerebrovascular prevention in acutely hospitalized older people
Aims: Antiplatelet therapy is recommended for the secondary prevention of cardio- and cerebrovascular disease, but for primary prevention it is advised only in patients at very high risk. With this background, this study aims to assess the appropriateness of antiplatelet therapy in acutely hospitalized older people according to their risk profile. Methods: Data were obtained from the REPOSI register held in Italian and Spanish internal medicine and geriatric wards in 2012 and 2014. Hospitalized patients aged ≥65 assessable at discharge were selected. Appropriateness of the antiplatelet therapy was evaluated according to their primary or secondary cardiovascular prevention profiles. Results: Of 2535 enrolled patients, 2199 were assessable at discharge. Overall 959 (43.6%, 95% CI 41.5–45.7) were prescribed an antiplatelet drug, aspirin being the most frequently chosen. Among patients prescribed for primary prevention, just over half were inappropriately prescribed (52.1%), being mainly overprescribed (155/209 patients, 74.2%). On the other hand, there was also a high rate of inappropriate underprescription in the context of secondary prevention (222/726 patients, 30.6%, 95% CI 27.3–34.0%). Conclusions: This study carried out in acutely hospitalized older people shows a high degree of inappropriate prescription among patients prescribed with antiplatelets for primary prevention, mainly due to overprescription. Further, a large proportion of patients who had had overt cardio- or cerebrovascular disease were underprescribed, in spite of the established benefits of antiplatelet drugs in the context of secondary prevention
