1 · What the graph read from it

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.

2 · The registry

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

Introduction: Castration-resistant prostate cancer (CRPC) is a heterogeneous and aggressive disease with limited treatment options, particularly in poorly differentiated cases that lack androgen receptor expression and progress rapidly even under conventional therapies. Here, we present a rare case of poorly differentiated CRPC that exhibited a remarkable response to carboplatin and paclitaxel therapy. Case Presentation: A 53-year-old man with metastatic, castration-sensitive prostate cancer (cT3bN1M1b, PSA 9.39 ng/mL, Gleason 4 + 5) underwent androgen deprivation therapy using bicalutamide and leuprorelin. Nine months later, he developed CRPC, despite undetectable PSA levels. A supraclavicular lymph node biopsy revealed a poorly differentiated carcinoma. Immunohistochemistry was negative for PSA and NKX3.1 and positive for CK5/6. These results excluded neuroendocrine carcinoma and supported a diagnosis of undifferentiated carcinoma. Systemic chemotherapy with carboplatin (area under the curve, five) and paclitaxel (200 mg/m Conclusion: This case highlights the potential efficacy of carboplatin and paclitaxel in treating poorly differentiated CRPC, suggesting the need for further investigation into platinum-based regimens for aggressive prostate cancer variants.
