Objective： The aim of the study was to investigate the correlations between pathological grade, serum prostatespecific antigen （PSA） and bone scintigraphy in the diagnosis of metastasis diseases for prostate cancers, and to explore the characteristics of bone metastases for prostate cancer. Methods： Seventy-seven newly diagnosed prostate cancers were reviewed in the study. All the cases underwent bone scintigraphy, total serum PSA measurement by luminescent immunoassay before operation and were classified according to post-operative pathology diagnosis. We analyzed the correlations of the bone metastasis incidences and different pathological grades or different PSA levels. Results： Bone scans were indicative of metastases in 33 cases （42.86%）. Significantly higher incidence of bone metastasis was observed in patients with poorly differentiated prostate cancer compared with patients with well （X2 = 10.880, P = 0.001 〈 0.05） and moderately （X2 = 6.166, P = 0.013 〈 0.05） differentiated prostate cancers. No significant difference between the well differentiated and moderately differentiated prostate cancers was found （X2 = 0.612, P = 0.434 〉 0.05）. The serum PSA concentration had＇significant correlation with the incidence of bone metastasis. In 26 patients with PSA 〈 20 ng/mL, 5 cases （19.23%） had bone metastasis while 28 of 51 cases （54.90%） with PSA〉 20 ng/mL had bone metastasis. The serum PSA concentration had positive correlation with pathological grades of prostate cancer （r = 0.535, P = 0.01）. Conclusion： Bone scintigraphy plays a great role in the diagnosis of bone metastasis for prostate cancer patients currently. The poorly differentiated prostate cancer and PSA 〉 20 ng/mL most likely suggested the possibility of bone metastasis.

ONECUT2 as a key mediator of androgen receptorindependent cell growth and neuroendocrine differentiation in castration-resistant prostate cancer

引用

Cancer Drug Resistance 2022年第1期5卷 165-170页

作者： WonSeok William Choi Julia L.Boland Jianqing Lin Division of Hematology/Oncology and Department of Medicine George Washington University HospitalGeorge Washington University School of Medicine and Health SciencesWashingtonDC 20037USA

Despite androgen dependence in a majority of castration-resistant prostate cancers,some cancer cells are independent of androgen receptor(AR)function,a feature of heterogeneity in prostate *** of the aggressive variants of prostate cancer that are AR independent is neuroendocrine prostate cancer(NEPC).This manuscript will focus on the new finding of human one cut domain family member 2(ONECUT2)transcription factor and its role in castration resistance,especially in NEPC.
