Screening for clonal hematopoiesis as a predictive marker for development of therapy-related myeloid neoplasia (t-MN) following neoadjuvant therapy for breast cancer: a Southwest Oncology Group study (S0012).

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
A serious complication associated with breast cancer treatment is the increased risk for development of therapy-related myeloid neoplasms (t-MN). To determine whether dose-intensive adjuvant regimens for breast cancer induce genetic damage to hematopoietic stem cells, defined by the emergence of clonal hematopoiesis, and whether detection of clonal hematopoiesis could be used as an early marker for the subsequent development of t-MN, the Southwest Oncology Group designed a pilot clonality investigation to estimate the incidence of clonal hematopoiesis during and shortly after completion of the dose intensive neoadjuvant regimens for high-risk breast cancer patients. Peripheral blood samples from 274 patients obtained prior to treatment, at time of surgery, and at 6 and 12 months post-surgery were examined by two different clonality assays: the HUMARA (HUMan Androgen Receptor) assay to estimate the incidence of early genetic damage by clonal proliferation, and microsatellite instability (MSI) testing to screen for LOH or defective DNA mismatch repair mechanisms. Clonal hematopoiesis was negative in 93.5% of the samples analyzed. Five patients showed a HUMARA-positive/MSI-negative pattern, and no patients showed a HUMARA-negative/MSI-positive pattern. With a median follow-up of 3.1 years, one patient in our study developed t-AML at 3 years 5 months after randomization. Our results indicate that clonal hematopoiesis assays performed within the 2 years following dose-intensive neoadjuvant therapy failed to identify an emerging clonal hematopoietic stem cell population. Longer clinical follow-up will be necessary to define better the positive predictive value of detecting clonal hematopoiesis in the HUMARA+/MSI- cases.
