Primary fallopian tube carcinoma presenting as an isolated sigmoid colon metastasis: a case report.
Article in Gynecology and pelvic medicine, 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
Background: Primary fallopian tube carcinoma (PFTC) is a rare gynecologic malignancy, and isolated colon metastasis as the initial manifestation of PFTC is exceedingly rare. To our knowledge, the present report describes the first case of PFTC presenting as an isolated sigmoid colon metastasis in the setting of completely normal uterine and adnexal imaging and negative serum tumor markers. Case Description: A 52-year-old postmenopausal woman who presented with 3 months of recurrent abdominal pain and diarrhea. Imaging revealed a solitary tumor in the sigmoid colon, while the uterus and bilateral adnexa appeared normal, and serum tumor markers were negative. After tumor resection, histopathological and immunohistochemical analysis confirmed a high-grade serous carcinoma (HGSC) of gynecologic origin. Subsequent laparoscopic hysterectomy and bilateral salpingo-oophorectomy identified a 1 mm lesion of HGSC at the fimbrial end of the fallopian tube. The patient received six cycles of adjuvant chemotherapy with carboplatin 500 mg combined with paclitaxel 80 mg, once every 3 weeks, for a total of six cycles, and achieved complete remission at the 1-year follow-up. Conclusions: This case underscores the crucial role of immunohistochemistry and thorough pathological examination in determining the primary origin of malignancies with atypical presentations. It emphasizes the need for precise diagnosis to inform treatment strategies and enhance prognostic outcomes.
