Successful Treatment of Patients with Refractory High-Grade Serous Ovarian Cancer with GOPC-ROS1 Fusion Using Crizotinib: A Case Report.
Article in The oncologist, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundRecently, multiple poly (ADP-ribose) polymerase (PARP) inhibitors have demonstrated excellent efficacy among patients with ovarian cancer with or without BRCA mutations. However, alternative therapeutic options are urgently required for patients who cannot benefit from conventional chemotherapy or PARP inhibitors. CASE PRESENTATION: A patient with high-grade serous ovarian carcinoma presented to our clinic after developing resistance to chemotherapy. Paired tumor-normal next-generation sequencing (NGS) was performed using peripheral blood to identify potential actionable mutations. NGS revealed the patient harboring a GOPC-ROS1 fusion, which was subsequently verified using a reverse transcription polymerase chain reaction assay. No germline or somatic mutation in BRCA1/2 or mismatch repair genes was detected. Therefore, the patient received crizotinib treatment. A rapid, favorable clinical response (partial response at 1 month) was observed, with further pathological response monitored and evaluated in follow-up interrogation.
conclusionThis study suggested that crizotinib was an off-the-shelf, practical, and ostensibly effective treatment option for patients with ovarian cancer with ROS1 rearrangement. NGS-based genetic testing may guide to plan therapeutic paradigms, and render precision medicine promising in ovarian cancer treatment. IMPLICATIONS FOR PRACTICE: Despite the previous report of ROS1 fusion in patients with ovarian cancer, it remains unknown whether patients can benefit from targeted therapeutic drugs. This study reports a GOPC-ROS1 fusion identified by next-generation sequencing in a patient with chemotherapy-resistant ovarian cancer. The patient was administered crizotinib and showed rapid, remarkable response. This study suggests that comprehensive sequencing should be offered for patients with ovarian cancer without effective therapeutic strategies, and crizotinib can be used to treat ROS1-rearranged ovarian carcinomas.
