Patterns and outcomes of current antitumor therapy for high-grade neuroendocrine neoplasms: perspective of a tertiary referral center.
Article in Journal of cancer research and clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePatients with metastatic high-grade neuroendocrine neoplasms (NEN) have an unfavorable prognosis. Treatment patterns and therapy outcome are scarcely evidenced, especially considering the WHO classification updates since 2017, and were thus investigated in this study.
methodsThis retrospective single-center analysis evaluated patients with neuroendocrine tumors grade 3 (NET G3) or neuroendocrine carcinomas (NEC) treated at the Medical University of Vienna since 2010. The primary endpoints were progression-free survival (PFS) and overall survival (OS) following first-line treatment.
resultsA total of 80 patients were included, 53 (66%) had NEC and 27 (34%) NET G3. Thirty patients had pancreatic NEN (38%), 29 gastrointestinal NEN (36%), 20 an unknown primary (25%), and one gall bladder NEC. All patients had metastatic disease, and all but four received systemic therapy. Platinum/etoposide was the most frequent palliative first-line treatment in NEC (41/47, 87%) and capecitabine/temozolomide (CAPTEM) in NET G3 (14/27, 52%). Overall, the median PFS and OS from first line start were 16.1 and 43.9 months for NET G3 and 6.1 and 12.7 months for NEC, respectively. Median PFS for platin/etoposide in NEC was 6.1 months (overall response rate [ORR] 56%) and for CAPTEM in NET G3 16.9 months (ORR 46%). Irrespective of the limited sample size (n = 4-11), second-line median PFS was short in NEC (FOLFIRI 2.8, FOLFOX 2.6, CAPTEM 5.4, other 2.6 months) and longer in NET G3 (8.2-11.1 months).
conclusionsThe present data from a large European NET center show that multiple treatment strategies are used in NEN and highlight the varying outcomes between NET G3 and NEC.
