Primary retroperitoneal squamous cell carcinoma: A case report.
Article in Oncology letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Retroperitoneal squamous cell carcinoma (SCC) is an extremely rare tumor originating from the retroperitoneum, with an unclear etiology and origin. Imaging studies are the preferred diagnostic modality for retroperitoneal tumors. The present study reports a case of retroperitoneal SCC and assesses its imaging characteristics. A 49-year-old female patient presented to the outpatient department of The Fifth Affiliated Hospital of Zunyi Medical University with a palpable abdominal mass detected 2 years ago. Ultrasound examination revealed two abnormal solid masses in the left adnexal region, suggesting a pelvic mass of undetermined origin. The patient was admitted to the hospital for further evaluation and treatment. Abdominal computed tomography (CT) and pelvic magnetic resonance imaging (MRI) revealed a retroperitoneal mass in the left pelvis. The patient subsequently underwent resection of the lesion and regional lymphadenectomy. Postoperative pathology confirmed poorly differentiated retroperitoneal SCC. After discharge, the patient received 6 months adjuvant chemotherapy and remained recurrence-free during the follow-up. Due to its deep location, proximity to several organs and non-specific clinical manifestations, retroperitoneal SCC is difficult to differentiate from other retroperitoneal tumors preoperatively using CT or MRI. Moreover, its treatment differs from that of common retroperitoneal tumors, such as leiomyosarcoma. Thus, summarizing the imaging features of retroperitoneal SCC is essential for guiding treatment selection and improving patient outcomes.
