When she developed progression on conventional chemotherapy, a trial of T. Erlotinib was given (since patient was a nonsmoker woman). Within a month, patient reported significant improvement in the dyspnea and did not require nebulization. 18F-FDG PET/CT was repeated after ~6 months, which showed significant response to the oral erlotinib monotherapy. Patient was doing well at 1-year follow-up, with only dermatological adverse effects (rashes). We reported the case of a 76-year-old man followed up since 2008 for a prostatic adenocarcinoma with pelvic and retroperitoneal nodes. He was initially treated by hormonotherapy with a good biological response. Twelve years after, he demonstrated an increased PSA level up to 10.2 ng/mL. He underwent a 68Ga-PSMA PET/CT, which shown an intense uptake by a left iliac extern mass, suspected of recurrence. The histology concluded in a hibernoma.

A 43-year-old woman with edema in both left upper limb and lower limb underwent lymphoscintigraphy to evaluate possible lymphedema. Two separate lymphoscintigraphies, one for the lower and the other for the upper limbs, were performed with interval of 3 days. Incidentally, an activity in the region of the thyroid glands was noted in the delayed images of both studies. Subsequently, Graves disease was diagnosed based on the patient's symptoms and the results of laboratory examinations.

Prostate cancer with NED (neuroendocrine differentiation) may occur in various stages of the disease, which is associated with a poor prognosis and treatment resistance. We present a case of a patient with metastatic castration-resistant prostatic cancer, who was treated with 7 cycles of 177Lu-PSMA and a very good response. Although only few foci with PSMA uptake were remained in the last posttreatment images, PSA levels dramatically began to rise. This raised suspicion for NED, and 68Ga-DOTATATE was done showing sufficient uptake to consider a trial of 177Lu-DOTATATE. The patient reported pain response, and PSA levels dropped after 1 cycle of the treatment.

Accurate assessment of the prognosis is critical for the rational treatment of neuroendocrine neoplasms (NENs). We performed a systematic review and meta-analysis of the prognostic value of 18F-FDG PET for NENs. PubMed and Embase databases were searched up to September 2020 for studies that evaluated 18F-FDG PET as prognostic factors in patients with NENs with overall survival (OS) and event-free survival (EFS) as outcomes. Hazards ratios (HRs) comparing high and low FDG uptakes were pooled using the DerSimonian-Laird method. Publication bias was assessed and adjusted for using the trim-and-fill method. Metaregression and subgroup analyses were performed to explore the cause of heterogeneity. Twenty-three studies (1799 patients) were included. The overall pooled HRs of high FDG uptake on EFS and OS were 2.84 (95% confidence interval [CI], 2.21-3.64) and 3.50 (95% CI, 2.42-4.12), respectively. Publication biases were present regarding both EFS and OS (P = 0.0342 and 0.0009, respectively). After adjustment, effect sizes remained significant for EFS and OS (adjusted HR, 2.26 [95% CI, 1.76-2.89]; 3.16 [95% CI, 2.42-4.12]). In metaregression analyses, the proportion of grade 3 tumors positively correlated with the HR of OS (adjusted P = 0.0422). 18F-FDG PET is a significant prognostic factor in patients with NENs. 18F-FDG PET might be a useful prognostic biomarker in conjunction with the histologic grade and can help select the optimal treatment. 18F-FDG PET is a significant prognostic factor in patients with NENs. 18F-FDG PET might be a useful prognostic biomarker in conjunction with the histologic grade and can help select the optimal treatment. A 77-year-old man was referred for a PET/CT 18F-FDG after incidental discovery of a lobulated jejunal lesion during surgery for an abdominal aortic aneurysm. The lesion was not removed due to the risk of digestive perforation. PET/CT 18F-FDG did not show pathologic hypermetabolism. Subsequently, we decided to perform PET/CT 18F-DOPA to better characterize this incidentaloma. A moderate uptake was showed, less than the pancreas. After multidisciplinary discussion, taking into account macroscopic and imaging aspects, the hypothesis of an ectopic pancreas was retained, allowing the exclusion of surgical excision.
