Lenalidomide and cyclophosphamide immunoregulation in patients with metastatic, castration-resistant prostate cancer.
Trial report in Clinical & experimental metastasis, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled 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.
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
Lenalidomide (LEN) and metronomic cyclophosphamide (CTX) regulate angiogenesis and immunosuppressive cells linked to the progression of metastatic castration-resistant prostate cancer (mCRPC). A phase-I/II, dose-escalation trial of LEN plus oral CTX was conducted in patients with previously treated mCRPC. In the phase-I study, CTX was given at 50 mg (day 1-28) and LEN at 10-25 mg (day 1-21) on a 28-day cycle using a "3+3" study design. In phase II, patients received LEN at 25 mg (day 1-21) with CTX at 50 mg PO QD (day 1-28) on a 28-day cycle. Nineteen patients in phase I were evaluable for toxicity. The maximum tolerated dose (MTD) was not observed at any of the dose levels (DLs) tested. Six patients received treatment in phase II before the trial was closed. A ≥ 50% reduction in PSA was observed in 31.7% evaluable patients. Radiographically, one patient had a partial response. Stable disease was documented in 68% of evaluable patients after two therapy cycles. Circulating tumor cells (CTCs) decreased in 22.7% and remained stable in 31.8% of patients. Baseline numbers of peripheral MDSCs (MDSC; Lin-DR(-)CD11b(+)) were significantly increased in patients versus normal donors, and were decreased by chemotherapy. At baseline, MDSCs correlated directly with CTCs, and inversely with T- and B cell frequency supporting their immunosuppressive activity. The combination of LEN and metronomic CTX can be safely administered, reversing cellular immunosuppression in this group of elderly patients with mCRPC. Further research is required to identify responsive subgroup(s) and validate the biomarkers.
