Twenty-four months progression-free survival (ongoing) for treatment of recurrent ovarian clear cell carcinoma with surufatinib in combination with toripalimab: a case report.
Article in BMC women's health, 2026. 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
Recurrent ovarian clear cell carcinoma (OCCC) remains a therapeutic challenge due to intrinsic chemoresistance and paucity of targeted options. Surufatinib is a multi-target tyrosine kinase inhibitor that may enhance antitumor immunity when combined with PD-1 blockade. We report a 53-year-old female with recurrent OCCC who developed a platinum-sensitive first relapse (platinum-free interval, 9.8 months) after adjuvant platinum-based chemotherapy and achieved a 24-month progression-free survival (ongoing) on surufatinib plus toripalimab. The best response was partial response, and treatment was well tolerated except for Grade 1 hemoptysis and Grade 1–2 proteinuria. Radiologic disease control was durable. However, because biomarker assessment relevant to immune checkpoint inhibition was not performed, the biological basis of response remains uncertain. This case suggests the clinical feasibility of surufatinib plus toripalimab and its association with durable disease control in an individual patient with recurrent OCCC. However, given the platinum-sensitive nature of the relapse, treatment efficacy should be interpreted cautiously. Further prospective studies incorporating biomarker assessment are warranted.
