Preoperative versus postoperative radiotherapy for localized soft tissue sarcoma treated with curative intent in a French tertiary center "SARCLOC".
Article in BMC cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundSoft tissue sarcomas of the extremities (E-STS) are rare and heterogeneous. Treatment combines surgery with preoperative or postoperative radiotherapy (RT) for deep, large, or high-grade tumors. We evaluate the effectiveness and toxicity in E-STS patients treated at our institution from 2015 to 2021. MATERIALS AND
methodsThis retrospective, single-center study, compared clinical and therapeutic characteristics, toxicities, and surgical complications by radiotherapy type. Local recurrence-free survival (LRFS), overall survival (OS), and recurrence-free survival (RFS) were estimated using the Kaplan-Meier method.
resultsWe included 158 patients; 124 (78%) received preoperative RT. The two groups (preoperative RT vs. postoperative RT) differed significantly in terms of median tumor size (111 vs. 67.5 mm, p < 0.01), perivascular involvement (51% vs. 29%, p = 0.03), and bone contact (32% vs. 12%, p = 0.02), but not in grade (grade 2 or 3: 65% vs. 74%, p = 0.72). Median follow-up was 2.9 vs. 5.1 years. Two-year LRFS was 82% [95%CI: 74-88] for both groups; OS was 87% [95%CI: 80-92] vs. 88% [95%CI: 71-95]; and RFS was 72% [95%CI: 63-79] vs. 70% [95%CI: 52-83]. Postoperative complications were 53% vs. 35%, with wound disruption at 39% vs. 15% and infections at 29% vs. 6%. Grade 2 or higher dermatitis was 16% vs. 29%, and RT discontinuation rates were 4% vs. 12% for the two groups, respectively.
conclusionDespite poorer prognostic factors in the preoperative RT group, LRFS and OS were comparable to those in the postoperative RT group. Postoperative complications were more frequent with preoperative RT, and treatment discontinuation was more common postoperatively.
