Neoadjuvant hyperthermic intraperitoneal chemotherapy: impact on chemotherapy response score and prognosis in high-grade serous ovarian carcinoma.

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
Background: This study aimed to assess the therapeutic effects of neoadjuvant hyperthermic intraperitoneal chemotherapy (NHIPEC) combined with neoadjuvant chemotherapy (NACT) in patients with high-grade serous ovarian carcinoma. Methods: This study used a retrospective cohort design. A total of 120 patients with ovarian cancer who received NACT and underwent interval debulking surgery (IDS) at our hospital between 2016 and 2018 were enrolled in this study. Thereinto, 67 patients received the NHIPEC combined with the NACT regimen, and the remaining 53 patients received only NACT as the control. The degree of tumor burden reduction in patients treated with different regimens was evaluated using the chemotherapy response score (CRS), and patient survival data were analyzed. Results: We found that the combination with NHIPEC is independently and positively correlated with a CRS reaching grade 3 (P=0.002), indicating that the combined treatment regimen has a significant advantage in improving the tumor response rate. Moreover, NHIPEC is an independent favorable prognostic factor for overall survival (OS) (P=0.032) and progression-free survival (PFS) (P=0.029). Further analysis showed that the median OS and PFS of patients receiving the combined treatment regimen were extended to 40 and 16 months, respectively, compared with 34 and 15 months in the group receiving only NACT. In addition, the incidence of grade 3-4 adverse events is comparable between the two groups. Conclusion: This study supports the notion that the treatment regimen of NHIPEC combined with NACT can improve tumor response in advanced ovarian cancer compared with NACT alone.
