Age-related genomic alterations and chemotherapy sensitivity in osteosarcoma: insights from cancer genome profiling analyses.
Article in International journal of clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundOsteosarcoma, the most common primary bone malignancy, has a complex genetic basis and two incidence peaks. In younger patients, the standard treatment involves wide surgical resection combined with adjuvant chemotherapy; however, the role of chemotherapy in elderly patients remains controversial. The aims of this study were to investigate genetic differences between younger and elderly patients with osteosarcoma and to identify genetic signatures associated with chemotherapy response.
methodsGenetic alterations were analyzed using cancer genome profiling data for 204 patients with osteosarcoma obtained from the Center for Cancer Genomics and Advanced Therapeutics.
resultsThe mutation spectrum was consistent with previous results for osteosarcoma. CCNE1, MCL1, MYC, and RB1 alterations were significantly associated with a younger age, while CDK4, CDKN2A, CDKN2B, H3F3A, KMT2D, MDM2, RAC1, and SETD2 alterations were significantly associated with an older age. Age, unsupervised clustering of gene alterations, and MYC amplifications were significantly associated with the response to ifosfamide. Notably, both clustered mutation signatures and MYC amplification were correlated with age.
conclusionsThese findings suggest that distinct oncogenic mechanisms contribute to differential sensitivity to chemotherapy in younger and elderly patients. Cancer genome profiling may aid in chemotherapy selection, and its early implementation is recommended to optimize treatment strategies.
