Objectives To investigate the expression level and its clinical significance of human epidermal growth factor receptor 2 (C-erbB-2),estrogen receptor (ER),progesterone receptor (PR),Ki67 and P53 in breast cancer tissues of elderly patients.Methods The expressions of C-erbB-2,ER,PR,Ki67 and P53 in 103 specimens of breast cancer tissues were assessed by immunohistochemistry(S-P),and their relationships with clinicopathological factors including tumor size,lymph node metastasis status and clinical stages were statistically analyzed.Results The positive rate of C-erbB-2,ER,PR,Ki67 and P53 in 103 cases was 17.5％ (18/103),64.1％ (66/103),54.4 ％ (56/103),70.9 ％ (73/103) and 66.0 ％ (68/103),respectively.The positive expression rates of C-erbB-2 and P53 were correlated with clinical stages and lymph node metastasis status(P＜0.05).The positive expression rate of Ki67 was correlated with clinical stages(P＜0.05),but not correlated with tumor size and lymph node metastasis status(P＞0.05).The positive expression rates of C-erbB-2,P53,ER and PR were irrelevant to tumor size(P＞0.05).Conclusions The expression of C-erbB-2,ER,PR,Ki67 and P53 could be biological markers for estimating the occurrence and progression of elderly breast cancer.Detection of C-erbB-2,ER,PR,Ki67 and P53 may help judge the clinical stages and lymph node metastasis status in elderly patients with breast cancer.

Objective:To assess the effectiveness and practical value of surgery in clinical treatment of cervical lymph node tuberculosis.Methods:110 patients receiving surgical treatment for tuberculosis at Hunan Provincial Chest Hospital between January 2020 and December 2022 were selected, all of whom were diagnosed with cervical lymph node tuberculosis.According to patient preferences, they were divided into two groups, a drug treatment group consisted of 60 patients receiving conventional Western medicine treatment and a surgical treatment group of 50 patients receiving surgical treatment.Statistical analysis was made to compare the clinical efficacy, recurrence rate, complications, quality of life, and patient satisfaction between the two groups.Results:The overall clinical effectiveness rate was higher in the surgical treatment group than in the drug treatment group(94.00% vs.70.00%, χ2=10.170, P=0.001), with the rate higher in the surgical treatment group than in the drug treatment group for patients under 60 years of age(64.29% vs.40.00%, χ2=-6.996, P=0.035), but there was no difference in therapeutic efficacy between the two groups for patients aged 60 and above(54.55% vs.40.00%, Z=3.842, P=0.146). Compared with the drug treatment group, the surgical treatment group had a lower recurrence rate(8.00% vs.46.67%, χ2=19.767, P<0.001)and a lower rate of complications(8.00% vs.21.67%, χ2=3.899, P=0.048), but higher scores of quality of life in all four domains(physical function: 64.02±4.49 vs.76.11±4.47, t=14.090, P<0.001; material life: 66.50±2.39 vs.81.03±2.28, t=32.417, P<0.001; psychological function: 62.98±2.51 vs.79.24±2.50, t=33.892, P<0.001; social function: 63.12±3.39 vs.76.08±3.51, t=19.645, P<0.001)and a higher level overall patient satisfaction(90.00% vs.66.67%, χ2=8.455, P=0.004). Conclusions:Surgical treatment for cervical lymph node tuberculosis patients has better efficacy, fewer complications and better prognosis and is clinically practical and highly valuable.
