Durable response to chemoimmunotherapy in a patient with refractory metastatic ovarian clear cell carcinoma: a case report and literature review.
Review in The oncologist, 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
objectiveOvarian clear cell carcinoma (OCCC) frequently exhibits resistance to conventional chemotherapy with limited treatment options. This study reports a heavily pretreated advanced case with liver metastases to investigate the efficacy of gemcitabine combined with PD-1 inhibitor in such refractory patients.
methodsWe present a case of stage IIIC OCCC that progressed after first-line platinum-based chemotherapy. The patient was treated with gemcitabine in combination with the PD-1 inhibitor toripalimab. Genetic alterations were analyzed using next-generation sequencing, and PD-L1 expression was assessed by immunohistochemistry (combined positive score [CPS]). Treatment response and safety profiles were regularly monitored.
resultsThe combination therapy induced a complete remission lasting over 24 months, with a manageable safety profile. Molecular profiling revealed a loss-of-function mutation in ARID1A, which may enhance tumor sensitivity to gemcitabine, while elevated PD-L1 expression (CPS = 30) may serve as a predictive biomarker for immunotherapy response in OCCC. Notably, the deep and durable clinical response observed suggests a potential synergistic effect between gemcitabine and immunotherapy, wherein ARID1A deficiency-induced chemosensitivity may prime the tumor microenvironment for enhanced immune checkpoint inhibition, offering a compelling rationale for this combination strategy in platinum-resistant OCCC.
conclusionThis study proposes a promising therapeutic strategy for advanced OCCC and supports the clinical value of molecular profiling-guided treatment. Both ARID1A status and PD-L1 expression warrant further validation as potential biomarkers in prospective clinical trials.
