The survival analysis and feasibility study of Pars Plana Vitrectomy (PPV) in the treatment of retinoblastoma.

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
purposeTo analyze the safety and efficacy of Pars Plana Vitrectomy (PPV) as a treatment for retinoblastoma patients and to evaluate the feasibility. METHODS AND PATIENTS: We collected 342 eyes who had PPV after systemic chemotherapy in our retrospective study, then analyze the 5-year overall survival and 5-year event-free survival rate, recurrence rate, and metastasis rate. The above data were used to evaluate the feasibility of PPV in the treatment of retinoblastoma.
resultsThe mean value of follow-up time was 62.9 months from PPV. Of all 342 eyes, 18% eyes underwent enucleation of the eyeball. Excluding Non-PPV related deaths eyes, the 5-year overall survival rates and event-free survival were 95% and 80%; the tumor recurrence rate and metastasis rate were approximately 26% and 1.2%, respectively; the mortality was 3.9%. And the incidence of high-risk pathological factors of enucleated eyes after PPV was 32%.
conclusionOur results suggest that Pars Plana Vitrectomy as a new approach to preserve the eyeball of RB children is feasible, especially for those patients who cannot be completely controlled by systemic chemotherapy or the tumors with vitreous seeds. Although the outcomes in our study are very optimistic, we also recommend an experienced eye surgeon to perform the operation and strictly control the indications for PPV surgery. And enough systemic chemotherapy is very important before and after surgery. LEVEL OF EVIDENCE: Treatment study (Retrospective comparative study), III.
