We present extended follow-up and an independent validation…

Neuroendocrine Tumors: Imaging Perspective

PET Clin. 2021 Jul;16(3):353-364. doi: 10.1016/j.cpet.2021.03.002. ABSTRACT This article summarizes the role of PET imaging for detection, characterization, and theranostic/therapy planning for neuroendocrine tumors. Topics in this article span overall imaging accuracy with mostly 68Ga-DOTA-peptide imaging as well as basic…

Current and future strategies for radiation therapy in gastric cancer

J Surg Oncol. 2022 Jun;125(7):1161-1175. doi: 10.1002/jso.26880. ABSTRACT Gastric cancers are heterogeneous. There are important differences between gastric and junctional tumors and a focus on evidence based on true gastric cancers is important to guide treatment decision and the design…

Quantitative 68Ga-DOTATATE PET/CT Parameters for the Prediction of Therapy Response in Patients with Progressive Metastatic Neuroendocrine Tumors Treated with 177Lu-DOTATATE

J Nucl Med. 2021 Oct;62(10):1406-1414. doi: 10.2967/jnumed.120.256727. Epub 2021 Feb 12. ABSTRACT The aim of this study was to determine whether quantitative PET parameters on baseline 68Ga-DOTATATE PET/CT and interim PET (iPET) performed before the second cycle of therapy are…

68Ga PET Imaging in Patients With Neuroendocrine Tumors: A Systematic Review and Meta-analysis

18F-DCFPyL PET/CT in Patients with Subclinical Recurrence of Prostate Cancer: Effect of Lesion Size, Smoothing Filter, and Partial-Volume Correction on PROMISE Criteria

J Nucl Med. 2020 Nov;61(11):1615-1620. doi: 10.2967/jnumed.120.241737. Epub 2020 Mar 20. ABSTRACT Our purpose was to determine the effect of a smoothing filter and partial-volume correction (PVC) on measured prostate-specific membrane antigen (PSMA) activity in small metastatic lesions and to…

[18F]DCFPyL PET-MRI/CT for unveiling a molecularly defined oligorecurrent prostate cancer state amenable for curative-intent ablative therapy: study protocol for a phase II trial

BMJ Open. 2020 Apr 22;10(4):e035959. doi: 10.1136/bmjopen-2019-035959. ABSTRACT INTRODUCTION: The oligometastatic (OM) disease hypothesis of an intermediate metastatic state with limited distant disease deposits amenable for curative therapies remains debatable. Over a third of prostate cancer (PCa) patients treated with…

A Prospective Study of 18F-DCFPyL PSMA PET/CT Restaging in Recurrent Prostate Cancer following Primary External Beam Radiotherapy or Brachytherapy

Int J Radiat Oncol Biol Phys. 2020 Mar 1;106(3):546-555. doi: 10.1016/j.ijrobp.2019.11.001. Epub 2019 Nov 12. ABSTRACT PURPOSE: Radio-recurrent prostate cancer is typically detected by a rising prostate-specific antigen and may reflect local or distant disease. Positron emission tomography (PET) radiotracers…

Curative-intent Metastasis-directed Therapies for Molecularly-defined Oligorecurrent Prostate Cancer: A Prospective Phase II Trial Testing the Oligometastasis Hypothesis

Eur Urol. 2021 Sep;80(3):374-382. doi: 10.1016/j.eururo.2021.02.031. Epub 2021 Mar 6. ABSTRACT BACKGROUND: The hypothesis of a curable oligometastatic prostate cancer (PCa) state remains to be clinically-proven. Conventional imaging often fails to localize early recurrences, hampering the potential for radical approaches.…
