The necessity of adjuvant surgery for patients with high-risk chemorefractory or relapsed gestational choriocarcinoma with complete remission after anti-PD-1 therapy.

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
objectiveAnti-programmed cell death protein 1 (PD-1) therapy has demonstrated favorable therapeutic responses in patients with chemorefractory gestational trophoblastic neoplasia. The need for combined surgery to remove resistant foci in patients treated with anti-PD-1 therapy after complete remission (CR), however, has not been investigated. We therefore compared the prognosis of patients with high-risk chemorefractory or relapsed choriocarcinoma who underwent anti-PD-1 therapy with or without surgery.
methodsPatients with high-risk chemorefractory or relapsed choriocarcinoma who experienced CR following immunotherapy in conjunction with either surgical or non-surgical interventions were selected at Peking Union Medical College Hospital (PUMCH) between August 2018 and December 2023. Study endpoints included progression-free survival (PFS) and overall survival (OS). The results were analyzed using Mann-Whitney U tests and Kaplan-Meier analysis.
resultsForty-three patients who received andi-PD-1 therapy were enrolled in this study, including 18 patients with surgery and 25 without. Most of the foci in the surgery group were solitary (77.8%). The median maximum diameters of resistant foci before immunotherapy were 2.9 (0.7-7.3) cm and 1.4 (0.8-11.2) cm in the surgery and non-surgery groups, respectively (p=0.184). The 2-year PFS rate was both 91.5% in the non-surgery group and 90.9% in the surgery group. The 2-year and 3-year OS rates were 100.0% in both groups. There was no significant difference in PFS (p=0.849) or OS (p=0.371) between the 2 groups.
conclusionThese results suggest that surgical resection of drug-resistant lesions may not be necessary in patients with high-risk chemorefractory or relapsed choriocarcinoma who achieve CR after anti-PD-1 therapy.
