Male Breast Cancer Complicated With Leukocytosis Resembling Leukemia Reaction After Chemotherapy: A Case Report.

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
introductionMale breast cancer (MBC) accounts for less than 1% of all cancers in men, with invasive ductal carcinoma being the most common type. The chemotherapy regimens used for MBC are similar to those for female breast cancer. However, the incidence of chemotherapy-induced complications such as leukocytosis resembling leukemia reaction is not well documented in MBC. This case highlights a rare complication in an MBC patient, induced by prophylactic PEG-rhG-CSF following chemotherapy. CASE PRESENTATION: A 51-year-old male with left breast invasive ductal carcinoma underwent modified radical mastectomy. Postoperative pathology revealed high-risk features, and the patient received 8 cycles of chemotherapy with the ddAC-T regimen, followed by PEG-rhG-CSF for febrile neutropenia prevention. After the fifth chemotherapy cycle, the patient developed leukocytosis resembling leukemia reaction, characterized by a white blood cell count exceeding 50 × 10
conclusionLeukocytosis resembling leukemia reaction induced by PEG-rhG-CSF post-chemotherapy is a rare complication, particularly in MBC patients. This case underscores the importance of careful monitoring and differential diagnosis to avoid misdiagnosis and unnecessary interventions. Personalized treatment strategies and dose adjustments for PEG-rhG-CSF are crucial in managing this rare reaction, emphasizing the need for awareness and individualized care in MBC patients undergoing chemotherapy.
