Prophylactic intestinal resection following carbon-ion radiotherapy for locally recurrent rectal cancer: a case report.
Article in Journal of surgical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Treatment of locally recurrent rectal cancer (LRRC) after surgery is often complex and challenging. A 52-year-old man received emergency surgery (Hartmann's procedure) for bowel perforation caused by a huge sigmoid colon cancer, followed by treatment for concurrent advanced lower rectal cancer with neoadjuvant chemoradiotherapy and abdominoperineal resection. A solitary lung metastasis emerged afterwards, and was surgically removed. However, the patient developed LRRC in front of the sacrum. As surgical resection for the local recurrence was considered too invasive, carbon-ion radiotherapy (CIRT) was performed as radical local therapy. Because the surrounding intestine was highly adherent to the tumor and there was a high risk of developing an ulcer, the intestine was prophylactically resected. The patient has remained relapse-free for 2 years and 6 months since the most recent surgery. CIRT for LRRC appears to represent a useful therapeutic option in combination with prophylactic intestinal resection.
