Anti-Estrogen Therapy Achieves Complete Remission and Stability in Recurrent Cervical Cancer: A Case Study.
Article in The American journal of case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 Studies using transgenic mouse models have demonstrated that estrogen is necessary for the development of cervical cancer, particularly in tissues responsive to estrogen. Estrogen also protects cervical cancer cells from apoptosis, suggesting its role in the survival and persistence of cancer cells. CASE REPORT An 84-year-old woman with diabetes mellitus, hypertension, and stage III chronic renal failure was diagnosed with cervical squamous cell carcinoma, FIGO stage IB2. She underwent complete concurrent chemoradiotherapy, but central recurrence was found 9 months later. However, instead of salvage chemotherapy, substitutionary anti-estrogens were given due to her poor medical condition and advanced age. Complete remission was noted after tamoxifen therapy. Since the cervical cancer relapsed again 40 months after tamoxifen use, the anti-estrogen therapy was shifted to letrozole. The SCC-Ag level decreased dramatically after letrozole therapy, and disease stability was achieved until 29 months afterward. After 5 years and 9 months of anti-estrogen use only, the patient died due to noncancer-related pneumonia and heart failure. CONCLUSIONS This report demonstrates the tumor-stabilizing and therapeutic effect of anti-estrogens in the treatment of squamous cervical carcinoma. Further clinical trials are warranted to evaluate the efficacy of anti-estrogen therapy in cervical cancer patients.
