[Clinical and pathological features of renal cell carcinoma with urinary tract tumor thrombus: 6 cases report and literature review].
Review in Beijing da xue xue bao. Yi xue ban = Journal of Peking University. Health sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo investigate the clinical characteristics, diagnosis and treatment of renal cell carcinoma with urinary tract tumor thrombus.
methodsFrom January 1, 2015 to December 31, 2019, patients with renal cell carcinoma complicated with urinary tract tumor thrombus who were hospitalized in the Peking University Third Hospital and Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed. Meanwhile, we reviewed the literature, and the reported patients of renal cell carcinoma with urinary tract tumor thrombus were also included in our study. The basic information, clinical manifestations, treatment, pathological characteristics and follow-ups of all the patients were analyzed.
resultsIn our study, 6 patients from the two hospitals and 16 patients from previous literature reports were included. There were 13 males and 9 females with an average age of 54.7 years (22-79 years). Fifteen patients had renal cell carcinoma on the left side, 6 on the right side, and 1 on the unknown side. Gross hematuria was the most common chief complaint, including 18 patients. One patient complained of weight loss, 1 patient complained of microscopic hematuria, and 1 patient was found by ultrasound examination. Tumor thrombus was classified as grade Ⅰ in 9 cases (the tumor embolus protruded into the renal pelvis, but did not reach the ureteropelvic junction), grade Ⅱ in 10 cases (the tumor embolus protruded into the ureter, but not into the bladder), and grade Ⅲ in 3 cases (the tumor embolus passed through the ureter and protruded into the bladder). Only 11 patients were diagnosed with renal cell carcinoma before operation. Radical nephrectomy was performed in 9 cases and nephroureterectomy in 12 cases. In pathological diagnosis, there were 15 cases of clear cell renal cell carcinoma, 1 case of papillary renal cell carcinoma, 1 case of chromophobe cell carcinoma, 1 case of mixed cell renal cell carcinoma, 4 cases of renal cell carcinoma with undetermined classification. Eleven patients were followed up for 3-31 months, and 3 patients had lung metastasis within 6 months.
conclusionRenal cell carcinoma with urinary tract tumor thrombus is rare in clinic. It needs to be differentiated from renal pelvis carcinoma in diagnosis. The treatment principle can refer to general renal carcinoma. For locally advanced cases, complete resection is the best treatment, and its oncological prognosis needs more long-term and large-scale follow-up observation.
