ObjectiveTo explore the expressions of survivin, p53, and Ki67 in recurrence or metastasis breast cancer tissue, and explore their correlations and clinical significance. MethodsEighty-six patients with the chest wall local recurrence, axillary or supraclavicular lymph node metastases get treated in this hospital between January 2005 and January 2010 were excised and the expressions of survivin, p53, and Ki67 were detected by immunohistochemistry test, then compared them between the recurrence and metastasis breast cancer tissues and the primary breast cancer tissues. ResultsThe positive expression rate of survivin, p53, and Ki67 in the recurrence and metastasis breast cancer tissues were significantly higher than those in the primary breast cancer tissues, survivin: 90.70% (78/86) versus 61.63% (53/86), χ2=20.014 895, Plt;0.001; p53: 68.60% (59/86) versus 52.33% (45/86), χ2=4.766 968, Plt;0.05; Ki67: 62.79% (54/86) versus 46.51% (40/86), χ2=4.597 927，Plt;0.05. The positive expression rates of survivin in the recurrence and metastasis patients with p53, Ki67 negative expression were significantly higher than those of the primary breast cancer tissue (70.37% versus 24.39%, χ2=14.071 113, Plt;0.05; 75.00% versus 39.13%, χ2=6.540 373, Plt;0.05). The correlation coefficient of survivin with p53 and Ki67 positive expressions in the recurrence and metastasis breast cancer tissue and the primary breast cancer tissue were 0.876 214, 0.773 643 and 0.725 164, 0.698 112, respectively, Plt;0.05. ConclusionThe positive expression rates of survivin, p53, and Ki67 which increase in recurrence and metastasis breast cancer tissue indicate bad prognosis.
ObjectiveTo investigate the values of serum CEA and CA19-9 in predicting postoperative recurrence and metastasis and prognosis for gastric cancer. MethodsPreoperative serum levels of CEA and CA19-9 were measured by electrochemiluminescence assay in 136 patients with gastric cancer. The relationships of serum CEA level, CA19-9 level to clinicopathologic features, postoperative recurrence and metastasis, and prognosis of gastric cancer were analyzed. Kaplan-Meier method (log-rank test) was used to survival analysis. ResultsThere were 67 patients with postoperative recurrence and metastasis in 136 patients with gastric cancer. The positive rate was 48.5% (66/136) for CEA and 43.4% (59/136) for CA19-9. There was a significant correlation between CEA level and T stage, TNM stage, lymph node metastasis, or vascular invasion (P=0.011, P=0.018, P=0.021, P=0.024). There was a significant correlation between CA19-9 level and T stage or lymph node metastasis (P=0.018, P=0.045). The rate of postoperative recurrence and metastasis was 60.6% (40/66) in positive CEA, 61.0% (36/59) in positive CA19-9, 38.6% (27/70) in negative CEA, and 40.3% (31/77) in negative CA19-9, respectively. The rate of postoperative recurrence and metastasis in the positive CEA or positive CA19-9 was significantly higher than those in the negative CEA or negative CA19-9 (P=0.010, P=0.016). Kaplan-Meier analysis showed that patients with positive CEA or positive CA19-9 had worse survival than those with negative CEA or CA19-9 (P=0.003, P=0.007). ConclusionsCEA and CA19-9 have important values in detecting recurrence and metastasis, predicting patient survival after gastric cancer surgery. Combined analysis of these markers is considered to be helpful for improving the prediction of the postoperative recurrence and metastasis and prognosis of gastric cancer.
Objective To investigate the relative factors on tumor reocurrance or matastasis for over five years survival patients after esophageal carcinoma resection. Method We followed up the patients underwent esophageal carcinoma resection in our hospital and discharged between October 1997 and October 2002. We analyzed the clinical data of 181 over five years survival patients with complete follow-up data. There were 148 males and 33 females with the mean age of 63.9 years ranging from 60-70 years. We summarized the follow-up data and carried on the univariate analysis of relatively recurrent data. Result The result of univariate analysis showed that tumor recurrence as well as matastasis statistically related with degree of differentiation, pTNM stage, whether there was lymph node metastasis or not, and the number of lymph node metastasis (P<0.05), but not with gender, age, the length of tumor, the site of tunor, or other clinicopathologic characteristics (P>0.05). Conclusion The main factors influencing over five years survival rate after esophageal carcinoma resection are pTNM staging when operating, lymph node metastasis or not, and the number of lymph node metastasis.
ObjectiveTo comparatively analyze risk factors that influence the postoperative recurrence and distant metastasis between Xinjiang Uygur and Han women with breast cancer. MethodsThe clinical data of Han and Uyghur women with diagnosis of breast cancer at Ⅰ-Ⅲ period were completely collected for retrospective analysis. Then logistic regression (univariate and multivariate) was performed for analyzing the risk factors that influenced recurrence and metastasis. ResultsA total of 728 patients were included. The recurrence and metastasis rates among Uyghur and Han patients 3 years after surgery were 28.4%, 9.8%, respectively, including local recurrence[11 Uyghur cases (6.5%) and 9 Han cases (1.6%)] and distant metastasis[37 Uyghur cases (21.8%) and 45 Han cases (8.0%)]. Significant differences were found between the two groups in tumour size and time from symptom occurrence to clinical visits (P<0.05). Pathological type, tumour size, axillary lymph node metastasis, clinical stage, ER and PR expression, and whether to accept a regular postoperative adjuvant therapy were associated with the recurrence and metastasis rate among the patients with breast cancer at Ⅰ-Ⅲ period (P<0.05). The results of multivariate logistic regression analysis showed that, the recurrence and metastasis rate of Uyghur patients was higher than that of Han patients with a significant difference (P<0.01). Pathological type, tumour size, and axillary lymph node metastasis number were the risk factors used to predict postoperative recurrence and metastasis among Uygur and Han patients; while ER positive expression, adjuvant radiation and postoperative chemotherapy were protective factors. ConclusionThe recurrence and metastasis rate of Uyghur patients with breast cancer is higher than that of Han patients. Pathological type, tumour size, and axillary lymph node metastasis number are the risk factors of postoperative recurrence and distant metastasis; while ER positive expression, adjuvant radiation and postoperative chemotherapy may inhibit the recurrence and distant metastasis of breast cancer.
