Objective To investigate the relationship between thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb) and clinicopathological features of breast cancer. Methods Thyroid function data, general clinical data and data reflecting pathological characteristics of breast cancer of 136 breast cancer patients admitted to the Department of Breast and Thyroid Surgery, People’s Hospital of Wuhan University from December 2019 to April 2022 were collected. According to the TPOAb and TGAb antibody levels of patients, 136 breast cancer patients were divided into positive group (antibody level ≥60 U/mL) and negative group (antibody level < 60 U/mL). The general clinical data, thyroid function, breast cancer markers, tumor size, pathological classification, clinical TNM stage, lymph node metastasis and immunohistochemical index expression characteristics of the two groups were analyzed. Results There was no statistically significant difference between the TPOAb positive group and the TPOAb negative group, as well as between the TgAb positive group and the TgAb negative group in terms of age, previous chronic medical history, surgical medical history and menstrual status of breast cancer patients (P>0.05), and there was no significant difference in the results of preoperative ultrasound and molybdenum target examination (P>0.05).Compared with the TPOAb negative group, the level of triiodothyronine (T3) in the TPOAb positive group was lower (P=0.020), and the level of thyroidstimulating hormone (TSH) was higher (P=0.001). TSH level in the TgAb positive group was higher than that in the TgAb negative group (P=0.036). There was no significant difference in tumor markers (carcinoembryonic antigen, carbohydrate antigen 125 and 153) and the number of lymph nodes cleared during operation between the positive and negative groups of TPOAb and TgAb (P>0.05). Compared with the respective negative groups, there was no significant difference tumor size, pathological classification, clinical TNM stage, lymph node metastasis, pathological molecular classification, and the expression of ER, PR and Ki-67 in the TPOAb positive group and the TgAb positive group (P>0.05). The positive rate of HER-2 expression in the TPOAb positive group was higher than that in the TPOAb negative group (P=0.033). There was no significant difference in HER-2 expression between the TgAb positive group and the TgAb negative group (P>0.05). There was no significant difference between the TPOAb positive group and the TPOAb negative group, as well as the TgAb positive group and the TgAb negative group in terms of chemotherapy, invasive carcinoma with carcinoma in situ, with benign lesions and nerve invasion (P>0.05). There was no significant difference between TPOAb positive group and negative group in vascular tumor thrombus rate and single cancer focus rate (P>0.05). Compared with the TgAb negative group, the TgAb positive group had a lower vascular tumor thrombus rate (P=0.034) and a higher single cancer focus rate (P=0.045). Conclusions Thyroid autoantibodies positive breast cancer patients have lower T3 level and higher TSH level, and the positive expression of thyroid autoantibodies is related to HER-2 expression, vascular tumor thrombus and the number of tumor foci in breast cancer. It suggests that thyroid autoantibodies TPOAb and TgAb may have an impact on the prognosis of breast cancer.
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.
ObjectiveTo investigate the expression of CD133 protein in primary lesions of gastric cancer and its clinical significance. MethodsThe expressions of CD133 protein in the primary lesion of tumor and normal gastric mucosa tissues confirmed by using histopathologic examination of 99 patients were detected by immunohistochemical staining. The correlation of CD133 protein expression with the clinicopathologic parameters and features after operation were analyzed. ResultsPositive cells of CD133 protein were localized in the gland parietal and cell membrane surface. The expression of CD133 protein in the cancer and normal gastric mucosa tissues were 29.29% (29/99) and zero, respectively (P=0.000). Expression of CD133 protein in tumor with diameter gt;5 cm was significantly higher than that in the tumor with diameter ≤5 cm (P=0.041). The expression of CD133 protein was correlated with TNM stage (P=0.044), lymph node metastasis (P=0.017), lymphatic vessel invasion (P=0.000), and vascular invasion (P=0.000). Logistic regression analysis revealed that invasion depth of tumor (P=0.011), lymph node metastasis (P=0.043), and TNM stage (P＝0.049) were independent risk factors for CD133 protein expression. Survival time of patients with positive expression of CD133 protein was significantly shorter than that negative expression of CD133 protein (P＝0.046). Cox proportial hazard regression model analysis demonstrated that lymph node metastasis (P=0.042), TNM stage (P=0.046), and positive expression of CD133 protein (P=0.046) were independent risk factors for patients survival. ConclusionThe CD133 protein expression in primary lesions is closely related with development, metastasis, and prognosis of gastric cancer.
Objective To investigate the relationship between skin/pectoral muscle invasion and the prognosis of male breast cancer. Methods Clinical data and follow-up information of 79 male breast cancer patients who received treatment between September 2008 to April 2020 in West China Hospital were retrospectively reviewed, to analyze the clinicopathological features of male breast cancer and prognostic value of skin/pectoral muscle invasion. Results Among 79 male breast cancer patients, a total of 23 patients (29.1%) were with skin/pectoral muscle invasion at diagnosis. All the patients were followed up, with a median follow-up period of 63.3 months (1.0–204.5 months). Within follow-up period, 8 patients (10.1%) suffered from relapse, 19 patients (24.7%, 19/77) suffered from metastasis, and 4 patients (5.1%) died. Multivariate Cox proportional risk regression model suggested that patients with skin/pectoral muscle invaded had poor disease free survival [RR=4.48, 95%CI (1.08, 18.52), P=0.038]. Conclusions Skinor pectoral muscle invasion might be a valuable prognostic factor for male breast cancer patients. However, limited by sample size, the conclusion should be proved by further high-level studies.
ObjectiveTo analyze the clinicopathologic features and prognosis of breast cancer patients with low human epidermal growth factor receptor-2 (HER2) expression. MethodsThe breast cancer patients underwent initially surgical resection in the First Hospital of Shanxi Medical University from October 2015 to October 2017 and met the criterion of this study were retrospectively gathered. Based on the immunohistochemical / in situ hybridization detection results, the patients were divided into three subtypes of HER2 zero, low, and positive expressions, and the differences in the clinicopathologic characteristics, overall survival (OS) and disease-free survival (DFS) of the three subtypes of breast cancer patients were compared. At the same time, the risk factors affecting the OS and DFS of breast cancer patients with low HER2 expression were analyzed. ResultsA total of 315 eligible patients were gathered in this study, including 68 patients with HER2 zero expression, 121 patients with low HER2 expression, and 126 patients with positive HER2 expression. There were no statistic differences in the menstrual status, T stage, and histological classification between the breast cancer patients with low HER2 and positive HER2 expressions (P>0.05), but the proportions of the patients with lymph node metastasis, histological grade Ⅲ, negative hormone receptor (HR) and high Ki67 expression in the low HER2 expression patients were lower than those in the positive HER2 expression patients. And compared with HER2 zero expression breast cancer patients, the proportions of premenopausal / perimenopausal, T2–4, N1–3, histological grade Ⅱ, ductal carcinoma, negative HR, and low Ki67 expression patients in the breast cancer patients with low HER2 expression were higher (P<0.05). While the survival curves of OS and DFS by Kaplan-Meier method had no statistic differences among the three subtypes of the breast cancer patients (χ2=0.070, P=0.966; χ2=0.362, P=0.835). The multivariate analysis results by Cox proportional hazards regression found that the low HER2 expression breast cancer patients with histological grade Ⅲ and negative HR had the higher risks of OS and DFS shortening (P<0.05). In addition, the risk of DFS shortening in the patients with T stage 2–4 and N stage 1–3 was increased (P<0.05). ConclusionsFrom the results of this study, breast cancer patients with low HER2 expression is different from the other two subtypes of breast cancer in terms of clinicopathologic characteristics. However, there are no statistical significances in comparing the OS and DFS of three types of breast cancer patients, but it is found that histological grading and HR are related to the OS and DFS of breast cancer patients with low HER2 expression, and it is also found that T stage and N stage are related to the DFS of breast cancer patients with low HER2 expression, so more attentions should be paid to the treatment plans.
Objective To investigate the correlation between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII) and clinicopathological characteristics and prognosis in patients with gastrointestinal stromal tumor (GIST). Methods The clinicopathological data and blood routine results of 101 patients with GIST who were treated surgically in the General Hospital Western Theater Command PLA from December 2014 to December 2018 were collected retrospectively, samples were obtained to calculate NLR, PLR and SII. The optimal cutoff value of NLR, PLR and SII were evaluated by receiver operating characteristic (ROC) curve. The Chi-square test and t-test were used to analyze the relationship between NLR, PLR, SII and clinicopathological characteristics of GIST. The Kaplan-Meier plots and the log-rank test were used to analyze the influence factors affecting the recurrence-free survival (RFS) of patients with GIST. Multivariate Cox regression analyses was used to identify the independent influence factors affecting the RFS of patients with GIST. Results The preoperative peripheral blood NLR, PLR and SII of patients with GIST were correlated with the tumor site, tumor diameter and modified NIH risk stratification (P<0.05), but not with the mitotic count of tumor cells (P>0.05). Kaplan-Meier plots and log-rank test showed that NLR, PLR, SII, surgical method, tumor site, tumor diameter, mitosis rate and modified NIH risk stratification were the influential factors of RFS in with GIST. The multivariate Cox regression analysis revealed that postoperative whether to accept regular imatinib adjuvant therapy (HR=32.876, P<0.001), modified NIH risk stratification (HR=129.182, P<0.001), and PLR (HR=5.719, P=0.028) were independent influence factors affecting the RFS of patients with GIST. Conclusions Preoperative peripheral blood PLR, NLR, and SII are correlated with clinicopathological characteristics such as the tumor location, tumor diameter and modified NIH risk stratification, and are the influencing factors of postoperative RFS in patients with GIST. PLR is an independent predictor of RFS in patients with GIST.
Objective To detect the expression of copine 1 (CPNE1) in the gastric cancer (GC) and investigate its association with prognosis. MethodsThe clinicopathologic data of 121 patients who underwent radical gastrectomy in the Department of General Surgery, The 940th Hospital of Joint Logistics Support Force of Chinese People’s Liberation Army from March 2017 to December 2018 were retrospectively collected. The protein expression of CPNE1 in the GC tissues was detected by immunohistochemical (IHC) staining, and its association with prognosis was analyzed. GC tissues and adjacent tissues samples from 16 patients in the same time were prospectively collected, and the mRNA and protein expressions of CPNE1 were detected by real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Multivariate Cox proportional hazards regression model was used to analyze the prognostic factors of GC patients. ResultsIHC staining results showed that the CPNE1 was mainly expressed in the cell membrane and cytoplasm of gastric epithelial cells, and the color showed different degrees of brown. Among the 121 patients, 70 (57.9%) had high CPNE1 protein expression and 51 (42.1%) had low CPNE1 protein expression. The RT-qPCR and WB results of 16 pairs of fresh tissue specimens showed that the expression levels of CPNE1 mRNA and protein in the GC tissues were higher than those in the corresponding adjacent tissues (CPNE1 mRNA mean value: 1.451 vs. 1.100, P=0.048; CPNE1 protein mean value: 0.995 vs. 0.521, P=0.001). The multivariate Cox proportional hazards regression analysis showed that the high protein expression of CPNE1 [HR (95%CI)=1.931 (1.123, 3.321), P=0.017] was the risk factor affecting the prognosis of the patients with GC. ConclusionCPNE1 highly expresses in GC tissues and is associated with a poor prognosis in patients with GC, and it may be a potential tumor biomarker.
ObjectiveTo analyze the clinicopathologic features of thyroid tumors with RAS gene mutation.MethodThe clinicopathologic data of thyroid tumor patients who underwent surgical treatment or biopsy and were diagnosed pathologically at the Department of Pathology of the Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2021 to June 2023, were collected. ResultsA total of 798 patients with thyroid tumors who met the inclusion criteria were collected, including 747 cases of follicular epithelial tumors and 51 cases of medullary thyroid carcinoma (MTC). Among 798 patients, the RAS gene mutations were detected in 36 cases (4.5%), including 25 (69.4%) patients with NRAS mutations, 8 (22.2%) patients with HRAS mutations, 3 (8.3%) patients with KRAS mutations, and 4 (1.1%) patients accompanied with TERT promoter mutations. Among 36 patients with RAS mutant thyroid tumors, the male to female ratio was 7∶11, with a median age of 48.5 years, with an average tumor diameter of 2 cm. The mutation rate of RAS gene in different histological types of thyroid tumors, from high to low, was highest in the thyroid follicular carcinoma (FTC, 25.9%), followed by differentiated high grade thyroid carcinoma (20.0%), anaplastic thyroid carcinoma (20.0%), noninvasive follicular thyroid neoplasm with papillary like nuclear features (18.2%), follicular variant of papillary thyroid carcinoma (FVPTC, 16.0%), and well-differentiated thyroid tumour of uncertain malignant potential (WT-UMP, 12.8%), the mutation rates of RAS gene in the FTC, FVPTC, and WT-UMP were significantly higher than that of the classical papillary thyroid carcinoma (P<0.001 1), and the mutation rate of RAS gene was the lowest in the classical papillary thyroid carcinoma (1.5%). A total of 35 patients were effectively followed up with an average follow-up period of 21.4 months, 6 of whom had cervical lymph node metastasis, 4 patients developed distant metastasis, and 1 patient with anaplastic thyroid carcinoma died. ConclusionsRAS gene mutation can occur in thyroid follicular differentiated tumors and MTC. NRAS mutation is more common. The mutation rate is the highest in FTC, is the lowest in classical papillary thyroid carcinoma. Differential diagnosis combined with tissue morphology and other molecular changes can provide a reference for guiding treatment and evaluating prognosis.
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.
