Cervical Neuroendocrine Carcinoma Presenting as Isolated Large Ovarian Metastasis: A Case Report.

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 Neuroendocrine carcinoma (NEC) of the cervix is rare and has high mortality and recurrence rates. The clinical symptoms of cervical NEC, such as abnormal vaginal bleeding and discharge, are similar to those of other cervical cancers. Here, we describe a case involving a 42-year-old woman with cervical NEC accompanied by an isolated large ovarian metastasis. CASE REPORT A 42-year-old woman had experienced abdominal discomfort for the past 4 months, along with a larger abdominal circumference. Physical examination revealed a 15-cm, solid, mobile, abdominal mass and a smooth cervix. Abdominal computed tomography revealed a hypoattenuating solid mass with a calcified component and indistinct borders, measuring 16.6×15.5 cm. Tumor marker levels were as follows: cancer antigen 125, 803.9 U/mL; carcinoembryonic antigen, 241.9 ng/mL. Preoperatively, we suspected a malignant ovarian tumor without any suspicion of cervical cancer. Intraoperatively, a 25×20-cm solid mass was found on the left adnexa with peritoneal wall and rectosigmoid adhesions. We performed a total abdominal hysterectomy with bilateral salpingo-oophorectomy, followed by peritoneal biopsy and omentectomy. Histopathological examination showed a 2.5-cm endocervical mass and a normal ectocervical epithelium. Immunohistochemistry revealed a small-cell cervical NEC with metastasis to the left ovary. The final diagnosis was a stage IB2 cervical NEC with ovarian metastasis. For treatment, we administered an etoposide-cisplatin adjuvant chemotherapy regimen. CONCLUSIONS NEC of the cervix can manifest as a large ovarian tumor, lack the usual indications for cervical cancer, and spread to the ovaries without metastasis to other organs.
