A case of complete response following the administration of pembrolizumab and metastasectomy for lung and bone metastases of bladder cancer.

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
introductionPatients with metastatic urothelial carcinoma have poor prognosis and limited treatment options. CASE PRESENTATION: The patient was a 60-year-old male with bladder cancer and multiple lung metastases. He underwent three courses of gemcitabine and cisplatin chemotherapy, despite left femoral bone metastases. Tumor resection and bone replacement surgery was performed. Following the administration of four courses of pembrolizumab, lung metastasis completely resolved. However, after nine courses, right femoral neck bone metastasis was observed; therefore, tumor resection and bone replacement surgery were repeated. Pathologically, PD-L1 expression was low in lung biopsy tissue and bone metastases. Pembrolizumab treatment continued for up to 20 courses; cancer recurrence and adverse events were not observed upon follow-up examination after 1 year.
conclusionPatients responding well to systemic therapy may have resectable metastatic sites, and long-term survival might be achieved with adjunctive metastasectomy. The effect of pembrolizumab was not associated with positive PD-L1 expression.
