Feasibility of Preoperative Dose-Painting Intensity Modulated Radiation Therapy (IMRT) for Borderline-Resectable Primary Retroperitoneal Sarcoma.
Article in Annals of surgical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
purposeThe role of radiation therapy (RT) in resectable retroperitoneal sarcoma (RPS) remains controversial; however, preoperative RT may play an important role in borderline-resectable (at risk of R2 resection) disease. We evaluated the outcome of such patients treated with preoperative dose-painting IMRT followed by planned resection.
methodsBetween January 2001 and December 2017, 30 patients with borderline-resectable primary nonmetastatic RPS (after multidisciplinary review) received preoperative dose-painting IMRT in this retrospective cohort study.
resultsMedian follow-up for all patients was 32 months. Median dose to the whole tumor/high-risk margin was 50.4 Gy/60.2 Gy. Sixteen patients were female, 24 were >50 years. Median tumor size was 9.2 cm. After RT, 6 did not have surgery. Of the 24 who were explored, 20 underwent complete gross resection. During RT, 7 of 30 patients developed acute grade 2+ toxicities: 5 fatigue, 1 nausea and vomiting, and 1 cystitis. RT was completed in 29 of 30 patients. Postoperatively, 12 of 20 patients developed grade 2+ complications: 2 gastropathy, 5 intraabdominal collections requiring drainage, 1 retroperitoneal bleed, and 3 delayed wound healing. Late grade 2+ toxicity was observed in 3 of 20 patients: 1 lymphedema with recurrent cellulitis, 1 chronic diarrhea, 1 gastrointestinal bleeding from anastomosis requiring transfusions, and 2 renal insufficiency. In those who underwent complete gross resection (n = 20, median follow-up 47 months), the 5-year local control was 57%, and overall survival was 46%. DISCUSSION: Preoperative dose-painting IMRT given to borderline-resectable RPS rendered 67% of patients resectable, provided a 5-year local control rate of 57%, which is similar to those with resectable disease, and had an acceptable morbidity profile.
