Surufatinib related nephrotic syndrome in a pancreatic neuroendocrine tumor: a case report and review of literature.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pancreatic neuroendocrine tumors (pNETs) are rare, heterogenous neoplasms originating from pancreatic neuroendocrine cells, which regulate hormone secretion and metabolic homeostasis. Surgery is the primary method of control and potential cure for pNETs and targeted therapies have also been investigated for low-grade inoperable or distant metastatic pNETs. Surufatinib, an oral angio-immuno kinase inhibitor, is approved for treating inoperable or late-stage, low-grade (G1 and G2), well-differentiated pNETs and extrapancreatic neuroendocrine tumors. This study describes a case of nephrotic syndrome in a middle-aged woman with pNETs. This patient showed nephrotic syndrome after surufatinib treatment 3 months and renal pathology suggested IgA nephropathy with moderate podocyte injury. However, the nephrotic syndrome was relieved after 2 weeks of discontinuation of surufatinib. After resuming treatment with low-dose surufatinib for 2 weeks, the random proteinuria quantification was increased and the proteinuria turned negative after discontinuation of surufatinib again. It provides a reference for surufatinib related nephrotic syndrome in patients with pNETs and the potential mechanism between surufatinib and podocyte injury in IgA nephropathy needs to be investigated.
