1 · What the graph read from it

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.

2 · The registry

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

aimsAccumulating evidence suggests that advanced age is associated with poor local control and prognosis in patients with soft-tissue sarcomas (STSs), highlighting the need to optimise treatment for this age group. However, real-world data on treatment details and outcomes in elderly patients are limited. This study aimed to clarify the role of perioperative radiotherapy (RT) for treating high-risk STSs in elderly patients.

methodsPatients aged ≥ 70 years who underwent surgery for localised, high-grade, deep-seated non-small round cell STSs measuring ≥ 5 cm were included in the Bone and Soft Tissue Tumour Registry in Japan. Patients with small-round cell STSs or myxoid liposarcomas, or those who received perioperative chemotherapy or intraoperative RT, were excluded.

resultsAmong the 1,214 patients who met the criteria, 47 (4%), 219 (18%), and 2 (0.2%) received neoadjuvant, adjuvant, and both neoadjuvant and adjuvant RT, respectively. The 5- and 10-year disease-specific survival (DSS) rates were 72.7% and 64.7%, respectively. Tumour size ≥ 10 cm, intralesional margin, and local recurrence were associated with poorer DSS; however, perioperative RT did not affect DSS. The 5- and 10-year cumulative probabilities of local recurrence (LR) were 14.6% and 19.5%, respectively. Trunk wall tumours, dedifferentiated liposarcomas, marginal margins, and intralesional margins were associated with a higher probability of LR. Adjuvant RT was associated with a reduced LR probability in patients with intralesional (p = 0.005) or marginal margins (p = 0.044); however, no such benefit was observed in patients with wide margins, who constituted the majority of the cohort, resulting in no significant association between perioperative RT and LR in overall analyses. In the propensity score-matched cohort, no significant differences in DSS or cumulative probability of LR were observed between patients with and without perioperative RT.

conclusionAdjuvant RT was associated with reduced LR rates in elderly patients with high-risk STSs who had intralesional or marginal margins. However, because most patients achieved wide margins and no benefit of perioperative RT was observed in this group, RT was not associated with reduced LR or improved survival in the overall or propensity score-matched analyses. Prospective trials are warranted to define the role of perioperative RT in elderly patients with high-risk STSs.
