A randomized Phase III trial commenced in Japan in March 2013. Post-operative adjuvant chemotherapy with etoposide plus cisplatin is the current standard treatment for resected pulmonary high-grade neuroendocrine carcinoma including small cell lung cancer and large cell neuroendocrine carcinoma. The purpose of this study is to confirm the superiority of irinotecan plus cisplatin in terms of overall survival over etoposide plus cisplatin as post-operative adjuvant chemotherapy for pathological Stage I-IIIA completely resected pulmonary high-grade neuroendocrine carcinoma patients. A total of 220 patients will be accrued from 54 Japanese institutions within 6 years. The primary endpoint is overall survival and the secondary endpoints are relapse-free survival, proportion of treatment completion, adverse events, serious adverse events and second malignancy. This trial has been registered at the UMIN Clinical Trials Registry as UMIN000010298 [http://www.umin.ac.jp/ctr/index.htm].

A 64-year-old woman underwent initial 18F-FDG PET/CT staging for a suspicious endometrial mass, which showed high uptake in the endometrial mass and a focal uptake in a known left thyroid nodule. Histology revealed a high-grade large cell neuroendocrine carcinoma of the endometrium with FIGO (International Federation of Gynecology and Obstetrics) stage Ib. Further explorations revealed a synchronous thyroid metastasis.

Methods: This study aims to compare the prognostic outcomes of NEC and MiNEN by analyzing the clinicopathological features of these diseases and exploring factors affecting progression after radical surgery. Additionally, we employed whole-exome sequencing to investigate the molecular mechanisms influencing the prognosis of both conditions.

Purpose: To determine whether renal cell carcinoma metastases (RCC-Mets) to the pancreas can be differentiated from pancreatic neuroendocrine tumors (PNETs) in patients with RCC on CT or MRI at presentation.
Methods: This retrospective study included patients with biopsy-proven RCC-Mets (n = 102) or PNETs (n = 32) at diagnosis or after nephrectomy for RCC. Inter-observer agreement (Cohen kappa) was assessed in 95 patients with independent reads by two radiologists, with discrepancies resolved by consensus for final analysis.

Purpose: We aimed to compare the diagnostic performance of 68Ga-FAPI-04 (FAPI) in comparison to 68Ga-DOTATATE (SSTR) PET/CT for patients presenting with recurrent medullary thyroid carcinoma (MTC).
Patients And Methods: Sixteen MTC patients with elevated calcitonin levels (>150 pg/mL) underwent FAPI and SSTR PET/CT. Two nuclear medicine physicians evaluated all images, categorizing lesions into locoregional metastases, mediastinal lymph nodes (LNs), liver, and bone metastases.

Medullary thyroid carcinoma (MTC), a rare neuroendocrine tumor comprising 3-5% of thyroid cancers, arises from calcitonin-producing parafollicular C cells. Despite aggressive behavior, surgery remains the primary curative treatment, with limited efficacy reported for radiotherapy and chemotherapy. Recent efforts have explored the pathogenetic mechanisms of MTC, identifying it as a highly vascularized neoplasm overexpressing pro-angiogenic factors.
