Sigmoid Colon Metastasis from Endometrioid Carcinoma after a Long Disease-Free Interval Following Radiotherapy for Vaginal Recurrence: A Case Report and Review of the Literature.
Article in Surgical case reports, 2026. 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
introductionColorectal metastasis from endometrioid carcinoma is exceedingly uncommon and has been reported only in isolated case reports. We describe a case of sigmoid colon metastasis occurring after a long disease-free interval following radiotherapy for vaginal recurrence. CASE PRESENTATION: A 76-year-old woman presented with bloody stool. She had undergone hysterectomy for endometrioid carcinoma 9 years ago and had achieved a complete response after chemotherapy and radiotherapy for vaginal recurrence 5 years ago. Colonoscopy revealed a circumferential tumor at the sigmoid-descending colon junction, and laparoscope-assisted sigmoidectomy was performed. Postoperative pathological and immunohistochemical examinations demonstrated that the lesion represented metastatic endometrioid carcinoma. The patient subsequently received adjuvant paclitaxel plus carboplatin and has remained disease-free for 25 months.
conclusionsThis case shows that distant colorectal metastasis may occur even after a long disease-free interval following treatment for endometrioid carcinoma. Careful evaluation for late recurrence remains important, and complete surgical resection may provide effective disease control when metastasis is limited and amenable to resection.
