''Prognostic significance of estrogen receptor, progesterone receptor, HER2/neu, Ki-67, and nm23 expression in patients with invasive breast cancer''.

Methods: Patients with IBC (n = 81; mean age = 51.9 ± 11.1 years) were prospectively enrolled at the Department of Oncology, Uludag University Medical Center, Bursa, Turkey. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded tissue sections. Results: We did not find any significant association between immunohistochemical expression of ER, PR, HER2/neu, Ki-67, and nm23 and the baseline characteristics of IBC patients. The median patient PFS was 30 months (range 22-45), and the median OS was 32 months (range 23-46). Stratification of the patient population according to nm23 immunohistochemical expression revealed a statistically significant difference in terms of both OS (p < 0.05) and DFS (p < 0.05). Multivariate Cox regression analysis indicated that tumor grade, axillary lymph node status, and nm23 immunohistochemical expression were the 3 main independent prognostic factors for PFS and OS in IBC patients. Conclusion: Reduced nm23 immunohistochemical expression is an independent negative prognostic factor for OS and PFS. Patients with negative nm23 expression may require a more intensive follow-up.eninfo:eu-repo/semantics/closedAccessOncologyImmunohistochemistryInvasive breast cancerNm23PrognosisSurvivalLymph-node metastasisHormone-receptorIn-situCarcinomaSuppressorBiologyProteinAdultBreast neoplasmsCarcinomaDisease-free survivalFemaleHumansImmunohistochemistryKaplan-meier estimateKi-67 antigenMiddle agedMultivariate analysisNeoplasm invasivenessNM23 nucleoside diphosphate kinasesPredictive value of testsProportional hazards modelsProspective studiesReceptor, erbB-2Receptors, estrogenReceptors, progesteroneRisk factorsTime factorsTurkeyArticle2-s2.0-8487957496235936518223818346OncologyNucleoside-Diphosphate Kinase; Metastasis; PrunesEpidermal growth factor receptor 2Estrogen receptorKi 67 antigenNucleoside diphosphate kinase NM23Progesterone receptorAdultArticleBreast cancerCancer patientCancer prognosisFemaleHumanHuman tissueImmunohistochemistryMajor clinical studyOverall survivalProgression free survivalProtein expressionTissue section2241-6293
