  • Analysis of relationship between diabetes mellitus and clinicopathologic features of thyroid papillary carcinoma

    ObjectiveTo investigate the relationship between clinicopathologic characteristics of patients with papillary thyroid carcinoma (PTC) and diabetes mellitus (DM), and to provide basis for individualized diagnosis and treatment.MethodsThe patients who underwent the first thyroid surgery in the Renmin Hospital of Wuhan University from January 1, 2017 to September 15, 2020 and were pathologically diagnosed as PTC were collected. According to the presence or absence of DM, the clinical features were compared.ResultsThere were 2859 patients without DM and 133 patients with DM in 2992 patients. In patients with or without DM, there were no differences in lymph node metastasis, multiple, bilateral tumors, and extrathyroid invasion between the two groups (P>0.05). However, compared with the PTC patients without DM, the proportion of women with DM was lower (58.65% versus 76.71%, P<0.01), the proportions of age >55 years old (92.48% versus 66.32%, P<0.01) and capsule invasion (67.21% versus 63.11%, P=0.04) with DM were higer. After adjusting for age and gender, the multivariate analysis showed that the risks of larger tumor and capsular invasion in the patients with DM was 1.51 times [95%CI (1.06, 2.16), P=0.02] and 1.75 times [95%CI (1.16, 2.64), P<0.01] respectively as compared with in the patients without DM.ConclusionsIn PTC patients with DM, proportion of women is lower, proportions of elderly population (age >55 years old) and patients with capsular invasion are higer, tumor is larger. Therefore, patients with DM must not neglect regular examination of thyroid morphology and function, and PTC patients should also pay attention to control of blood glucose.

  • Clinicopathological features and guiding significance for radiotherapy of pT1-2N1M0 breast cancer with different molecular subtypes

    Objective To investigate the prognostic differences and decision-making role in postoperative radiotherapy of four molecular subtypes in pT1-2N1M0 stage breast cancer. Methods The clinicopathological data of 1526 patients with pT1-2N1M0 breast cancer treated at West China Hospital of Sichuan University between 2008 and 2018 were retrospectively analyzed. χ2 test was used to compare the clinicopathological features among patients with different molecular subtypes. Kaplan-Meier survival analysis and log-rank test were used to draw the survival curves and compare the overall survival (OS) and breast cancer-specific survival (BCSS) among patients with different molecular subtypes. Cox regression model was used to determine the influencing factors of OS of patients after radical mastectomy. Results Among the 1526 patients with pT1-2N1M0 breast cancer, there were 674 cases (44.2%) of Luminal A subtype, 530 cases (34.7%) of Luminal B subtype, 174 cases (11.4%) of human epidermal growth factor receptor 2 (Her-2) overexpression subtype, and 148 cases (9.7%) of triple-negative subtype. The 5-year OS rates of Luminal A, Luminal B, Her-2 overexpression and triple negative patients were 98.6%, 94.3%, 95.5% and 91.2%, respectively (χ2=11.712, P=0.001), and the 5-year BCSS rates were 99.3%, 94.6%, 95.5% and 92.5%, respectively (χ2=18.547, P<0.001). Multiple Cox regression analysis showed that menstrual status [hazard ratio (HR)=0.483, 95% confidence interval (CI) (0.253, 0.923), P=0.028] and whether endocrine therapy [HR=2.021, 95%CI (1.012, 4.034), P=0.046] were prognostic factors for the 5-year OS rate of breast cancer patients after radical mastectomy (P<0.05). However, it failed to reveal that Luminal subtypes and postoperative radiotherapy were prognostic factors for the 5-year OS rate (P>0.05). Conclusions In pT1-2N1M0 breast cancer patients, the 5-year OS rate and 5-year BCSS rate in triple-negative patients are the lowest. The relationship between Luminal classification, postoperative radiotherapy and survival in patients after radical mastectomy needs further study in the future.

  • Clinical Analysis and Recognition on Surgical Treatment of Remnant Gastric Cancer

    Objective To analyze surgical treatment and clinicopathologic features of remnant gastric cancer,and to recognize the strategies of treatment. Methods The clinical data of 26 cases patients with remnant gastric cancer diagnosed by endoscopy and pathological examination and underwent surgical treatment were retrospectively analyzed in our hospital between January 2004 and March 2011.In this study,14 cases of remnant gastric cancer from benign disease (RGCB) and 12 cases of remnant gastric cancer after stomach cancer operation (RGCC) were included.The clinical findings,Helicobacter pylori (HP) infection,surgical methods, histopathological features,and prognosis were analyzed.Results The patients developed a carcinoma in the gastric remnant about 15-44 years after operation for benign disease (median 26.3 years) and about 1-10.5 years after gastric cancer operation (median 4 years),and there was significant differences of the two groups(P<0.05).HP infection of the gastric remnant was found in 73.1%(19/26) patients,and infection rate of patients was 71.4%(10/14) in RGCB and 75.0%(9/12) in RGCC, but there was no statistical different in two groups (P>0.05).All 26 patients underwent surgical procedure,and the rate of radical resection was 46.2% (12/26), which was 57.1% (8/14) in RGCB and 33.3% (4/12) in RGCC respectively,there was no statistical different (P>0.05).Among the 12 cases underwent radical resection, the highest lymphatic metastasis rate was in No.3 group (83.3%, 10/12),which came in second in lymph node of mesojejunum or splenic hilum (33.3%, 4/12).Postoperative pathological staging was as follows:stageⅠin 3 cases, stageⅡ in 2 cases, stage Ⅲ in 14 cases and stage Ⅳ in 7 cases. In 18 patients underwent tumor excision,the metastasis of lymph node occurred in 13 cases (72.2%),and the pancreas,transverse colon,or spleen were invaded in 13 cases according to histopathological results. Meanwhile,peritoneal metastasis were founded in 8 cases patients,and the peritoneal metastasis rate of patients with RGCB (14.3%;2/14) was significantly lower than that with RGCC (50.0%, 6/12), P<0.05.The overall one-year survival rate and three-year survival rate was 54.5% and 38.5%,respectively, and the survival time was 2-61 months (median 12 months).Survival analysis indicated that pathological stage and radical resection were significant prognostic factors for patients with remnant gastric cancer(P<0.01),and radical resection was an independent prognostic factor (P<0.05),while age,gender,disease of first operation, degree of differentiation and HP infection were not (P>0.05). Conclusions Early detection and standard radical resection are the key factor to improve the prognosis of patients with remnant gastric cancer and laparoscopic exploration may minimize unnecessary injures of surgery.Because of the different clinical characteristics,strategy of treatment for RGCC and RGCB shall be discriminatory.

  • Relations between SCUBE3 or SP1 expression and clinicopathologic characteristics and prognosis of patients with breast cancer

    ObjectiveTo detect the expressions of signal peptide-CUB-EGF-like domain containing protein 3 (SCUBE3) and specificity protein 1 (SP1) in breast cancer tissues, and explore relations between their protein expressions and clinicopathologic features or prognosis.MethodsFrom February 2013 to October 2015, the breast cancer tissues and the corresponding adjacent normal breast tissues of 80 women patients with breast cancer in the Mianyang Central Hospital were selected, and the expressions of SCUBE3 and SP1 proteins in the tissues were detected by immunohistochemistry. The relations between the expressions of SCUBE3 and SP1 and clinicopathologic parameters of breast cancer were analyzed, the correlation between the SCUBE3 and SP1 was analyzed by Spearman rank correlation analysis. Kaplan-Meier method was used to analyze the survival of patients with breast cancer; and Cox proportional hazards regression model was used to analyze the risk factors of overall survival of patients with breast cancer.ResultsThe positive rates of SCUBE3 and SP1 proteins expressions in the breast cancer tissues were higher than those in the corresponding adjacent normal breast tissues (P<0.05). The positive rates of SCUBE3 and SP1 protein expressions were higher in the breast cancer tissues with lymph node metastasis and molecular subtypes of Luminal A or B (P<0.05), and the positive rates of SCUBE3 protein expression were higher in the breast cancer tissues with TNM stage Ⅱ–Ⅳ and high Ki67 (P<0.05). The retsult of Spearman rank correlation analysis showed that the positive rates of SCUBE3 and SP1 proteins expressions in the breast cancer tissues was positive correlation (χ2=7.979, rs=0.316, P=0.005). Kaplan-Meier curve showed that the overall survival of the patients with positive expression of SCUBE3 or SP1 protein was worse than that of the patients with negative expression (χ2=4.042, P=0.044; χ2=10.676, P=0.001). The Cox proportional hazards regression model multivariate analysis showed that the positive SCUBE3 (HR=6.020, P=0.016), positive SP1 (HR=4.077, P=0.018), lymph node metastasis (HR=3.518, P=0.017), and higher Ki67 expression (HR=7.989, P<0.001) were the independent risk factors of overall survival for the patients with breast cancer.ConclusionPositive rates of SCUBE3 and SP1 proteins expressions in breast cancer tissues are higher and there is a positive correlation between them, which are closely related to clinicopathologic parameters such as lymph node metastasis and molecular subtypes and prognosis of patients with breast cancer.

  • Effect of extranodal extension of axillary lymph node metastasis on prognosis of patients with triple-negative breast cancer

    ObjectiveTo investigate the effect of extranodal extension of axillary lymph nodes metastasis on the prognosis of patients with triple-negative breast cancer (TNBC). MethodsThe TNBC patients with axillary lymph node metastasis admitted to the Nanyang Central Hospital from January 2017 to January 2019 were collected. The clinicopathologic characteristics and prognosis of TNBC patients with or without extranodal extension were analyzed and compared, and the factors affecting prognosis were analyzed. ResultsA total of 216 patients were included, including 123 patients without extranodal extension and 93 patients with extranodal extension. Compared with the patients without extranodal extension, the proportions of the patients with histological grade Ⅲ, 10 or more metastatic lymph nodes, and 5 cm or greater tumor diameter were higher in the patients with extranodal extension (P<0.05). The results of multivariate analysis showed that the 10 or more metastatic lymph nodes was the risk factor affecting the overall survival (OS) and disease-free survival (DFS) of the TNBC patients (P<0.05), and the histological grade Ⅲ and lower human epidermal growth factor receptor-2 (HER-2) expression were the risk factors affecting the OS of the TNBC patients (P<0.05), as well as the extranodal extension was the risk factor affecting the DFS of the TNBC patients (P<0.05). The 5-year cumulative disease-free survival rate of the patients with extranodal extension was worse than that of the patients without extranodal extension (70.2% vs. 83.3%, χ2=6.934, P=0.008). The 5-year cumulative overall survival rate had no statistically significant difference between the them (75.3% vs. 82.1%, χ2=1.969, P=0.161). ConclusionsFrom the results of this study, the prognosis of TNBC patients with extranodal extension is worse. Especially the patients with histological grade Ⅲ, 10 or more metastatic lymph nodes, and with lower HER-2 expression should be paid attention.

  • Expression of Krüppel like factor 8 in breast cancer and its clinical significances

    ObjectiveTo detect the expression of Krüppel like factor 8 (KLF8) in breast cancer tissues and cells and to explore the clinical significance of KLF8.Methods① The Oncomine database was used to analyze the differential expression of KLF8 mRNA in the breast cancer tissues. The Kaplan-Meier Plotter database was used to analyze the relationship between KLF8 mRNA expression and prognosis (relapse free survival, overall survival, post-progression survival, and distant metastasis-free survival) of patients with breast cancer. ② The quantitative real-time PCR (qRT-PCR) and Western blot were used to detect the KLF8 expression levels in the 16 clinical patients with breast cancer and 7 breast cancer cell lines (MDA-MB-231, MCF-12A, Hs-578T, MCF-7, BT-474, MDA-MB-453, ZR-75-30) and normal breast epithelial cell lines MCF-10A, and the immunofluorescence was used to further detect the localization of KLF8 expression in the 2 breast cancer cell lines with higher KLF8 expression level. ③ The immunohistochemistry was used to detect the expression of KLF8 protein in 135 cases of breast cancer tissue microarrays, and the relationships between KLF8 protein expression and clinicopathologic characteristics or overall survival were analyzed.Results① The Oncomine database showed that KLF8 mRNA expression in the breast cancer tissues was higher than that in the normal breast tissues (P<0.001). The median KLF8 mRNA expression level was taken as the cut-off point for high or low KLF8 expression. The results of Kaplan-Meier Plotter data analysis showed that the prognosis (relapse free survival, overall survival, postprogression survival, and distant metastasis-free survival) of patients with low KLF8 mRNA expression were better than those of patients with high KLF8 mRNA expression (P<0.05). ② The results of qRT-PCR and Western blot all showed that the KLF8 mRNA and protein expression levels in the breast cancer tissues were higher than those in the adjacent normal tissues (P=0.002, P<0.001). In addition, the Western blot results showed that the expression of KLF8 protein in the 7 breast cancer cell lines was higher than that in the normal breast epithelial cell lines MCF-10A respectively, and KLF8 protein mainly expressed in the cytoplasm of breast cancer cells and highly expressed in the nuclear of a few cells. ③ There were 63 cases of high KLF8 expression and 72 cases of low KLF8 expression by the immunohistochemical analysis of 135 patients with breast cancer tissue microarray (the H-score of the immunohistochemical test results was 75 as the cut-off point, H-score >75 was the high KLF8 expression and H-score ≤75 was the low KLF8 expression), the differences of statuses of estrogen receptor (ER) and progesterone receptor (PR) between the patient with high KLF8 expression and low KLF8 expression were significant (P<0.05). The Kaplan-Meier survival curve analysis showed that the prognosis of patients with high KLF8 expression was worse than that of patients with low KLF8 expression (P=0.002). The univariate analysis showed that the TNM stage, statuses of ER and PR, and KLF8 expression were related to the prognosis of patients with breast cancer (P<0.05), further multivariate Cox proportional hazards regression analysis indicated that the later stage of TNM and high KLF8 expression were the independent risk factors (P<0.05).ConclusionsThe results of this study suggest that KLF8 highly expresses in both breast cancer tissues and breast cancer cells, which is related to the statuses of ER and PR and prognosis of patients with breast cancer. KLF8 might be involved in the progression of breast cancer as an oncogenic gene, or it might provide a new direction for prognosis judgment and molecular targeted therapy of breast cancer.

  • Association of Controlling Nutritional Status score with prognosis and clinicopathological characteristics of patients with non-small cell lung cancer: A systematic review and meta-analysis

    ObjectiveTo assess the prognostic significance of the Controlling Nutritional Status (CONUT) score in patients with non-small cell lung cancer (NSCLC) and its association with clinicopathological characteristics. MethodsThe relevant studies investigating the association between CONUT score and prognosis of NSCLC patients were systematically searched in the PubMed, Web of Science, EMbase, Cochrane Library, CNKI, Wanfang Database and other databases from their inception to July 2023. Two independent researchers screened the references according to predefined inclusion and exclusion criteria, extracted data and conducted quality assessment. The quality of included references was evaluated using New Castle-Ottawa Scale (NOS). The meta-analysis was performed using Stata 17.0 software, and a combined hazard ratio (HR) or odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the association of CONUT score with prognosis and clinicopathological characteristics in NSCLC patients. ResultsA total of 17 cohort studies, comprising 5182 NSCLC patients with stage Ⅰ-Ⅳ, were included in this analysis. All studies had a NOS≥6 points. The meta-analysis showed that there was a significant correlation between CONUT score and overall survival (OS) as well as disease-free survival (DFS) among NSCLC patients: the higher the score, the shorter the OS [HR=1.87, 95%CI (1.58, 2.21), P<0.001] and DFS [HR=1.91, 95%CI (1.63, 2.24), P<0.001]. These differences were statistically significant. Furthermore, CONUT score was significantly associated with age, smoking status, tumor stage, and N stage (P<0.05). ConclusionA higher CONUT score is associated with a poorer OS and DFS in patients with NSCLC, and CONUT score can be used as a potential predictor of NSCLC prognosis.
