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.
ObjectiveTo investigate the prognostic factors for inflammatory breast cancer based on the data from West China Hospital with a relatively large sample.
MethodsClinical data of 41 patients with histopathologically confirmed inflammatory breast cancer (IBC) who received treatment at West China Hospital Oncology Center of Sichuan University between January 2009 and December 2014 were collected and analyzed. Log-rank test and Cox regression model were used for statistical analysis.
ResultsIn the study, negative estrogen receptor, negative progestrone receptor and positive human epidermal growth factor receptor-2 were identified in 58.5%, 61.0% and 34.2% of the inflammatory breast cancer tissues, respectively. Progress free survival (PFS) were between 2 and 60 months, with a median of 35 months. Univariate analysis showed that Tumor Node Metastasis (TNM) stage (P=0.016) and therapeutic effect (P=0.002) influenced the survival. Multivariate analysis showed that TNM stage (P=0.006), therapeutic effect (P=0.002), and anthracycline-taxane based chemotherapy (P=0.041) were the significant prognostic factors.
ConclusionTNM stage is the major prognostic factor for IBC. Preoperative chemotherapy with paclitaxel-epirubicin combination can improve the PFS of IBC. Comprehensive treatment mode with operation is recommended for the treatment of IBC.
Objective
To analyze the clinical and pathological features of lung cancer with metastasis, explore the regularity and characteristics of the location of metastasis, and provide reference for future clinical treatment.
Methods
A total of 658 patients with lung cancer treated in West China Hospital of Sichuan University from January 2008 to December 2014 were enrolled in this study. The effect of different clinical and pathological characteristics on different locations of metastasis was analyzed by χ2 test and logistic regression.
Results
Adenocarcinoma was the main pathological type (342 cases, 52.0%), and bone (150 cases, 22.8%) and pleura (118 cases, 18.0%) were the most common distant metastasis. Compared with patients with no corresponding metastasis, patients with age <60 years took bigger proportions in patients with bone, brain and mediastina metastasis ( P<0.05). Furthermore, logistic regression analysis showed that the younger patients were more likely to have brain metastasis (P=0.024). Besides, the elder patients were more common in those with liver metastasis (P<0.001). The proportion of males was higher in the patients with lymph node metastasis than those without lymph node metastasis (P=0.010); however, the proportion of females was higher in patients with bone or pleural metastasis than those without bone or pleural metastasis (P<0.05). There was no significant difference in gender among patients with brain, lung, liver, adrenal and mediastinal metastases (P>0.05).
Conclusions
Bone and pleura are the most common sites of metastasis of lung cancer. The age structure of brain metastasis tends to be younger.
ObjectiveTo observe the clinical and pathological features of choroidal malignant melanoma (CM). MethodsA retrospective case study. From 2011 to 2021, paraffin specimens from 15 eyes of 15 CM patients diagnosed by pathological examination in the Department of Pathology, the Second Affiliated Hospital of Soochow University were included in the study. The age, gender, clinical manifestations, treatment plan and pathological examination results of patients were collected retrospectively through the hospital information system. The clinical characteristics, immunohistochemical staining and molecular pathological characteristics were analyzed. ResultsAmong the 15 cases, 8 males and 7 females. The average age was 61. All patients were monocular paroxysm. There were 8 cases of decreased vision, blurred vision and dark shadow in front of the eyes; 1 case had red eye, lacrimation and purulent secretion; 2 cases had visual loss and no light perception; 4 cases had retinal detachment. The average diameter of the tumors was 1.4 cm. The general appearance of the tumor was hemispherical, “mushroom-shaped” or flat diffuse. Most of the tumor cells were arranged in solid, flaky and cross clusters, and some of them were arranged in false “chrysanthemum form” around the blood vessels with necrosis. In 15 eyes, spindle-cell type, epithelioid type and mixed cell type were 6, 2 and 7 eyes, respectively. The cytoplasm was partly double stained or eosinophilic, partly clear, and partly rich in pigment. The cells had poor adhesion, marked atypia, rough chromatin, frequent mitotic figures, and prominent nucleoli . Immunohistochemical staining was positive for HMB45, SOX10, S100 and Melan-A in 15 patients, but negative for epithelial markers AE1/3, lymphatic markers LCA, neuroendocrine markers CgA and Syn. Genetic testing results showed that none of the patients found C-KIT, BRAF, NRAS gene mutations. Fifteen patients were followed up for 8-96 months, of which 12 survived and 3 died after recurrence and/or metastasis. ConclusionCM has no specific clinical clinical manifestations, and he diagnosis depends on histological morphology and immunohistochemical staining.
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.
Objective
To investigate relationship between androgen receptor (AR) and clinicopathologic features of patients with triple negative breast cancer (TNBC) in Xinjiang.
Methods
The clinical data of Han and Uygur patients with TNBC from the First Affiliated Hospital of Xinjiang Medical University from December 2012 to December 2016 were retrospectively analyzed. And the expression of the AR and the clinicopathologic features of the patients with TNBC were extracted. The results were analyzed by SPSS 19.0.
Results
A total of 178 patients with TNBC were included, including 127 Han and 51 Uygur patients. The positive rate of the AR expression in the 178 patients with TNBC was 21.3% (38/178), which was significantly related to the expression of Ki-67 (χ2=15.196, P<0.001), was not related to the ethnicity (χ2=0.203, P=0.688), age (χ2=0.221, P=0.715), tumor size (χ2=0.047, P=0.855), lymph node status (χ2=0.874, P=0.354), or histological grade (χ2=0.001, P=1.000). And there were no statistically significant differences in the clinicopathologic features between the Han patients with TNBC and the Uygur patients with TNBC.
Conclusion
AR positive expression is related to Ki-67, but clinicopathologic features have no significant differences between Han and Uygur patients with TNBC in Xingjinag.
ObjectiveTo analyze the clinicopathologic features of elderly patients with triple-negative breast cancer (TNBC) and explore the influencing factors of postoperative prognosis.MethodsThe TNBC patients who were pathologically confirmed in the Affiliated Hospital of Southwest Medical University from January 1st, 2013 to January 1st, 2014 were retrospectively collected. The differences of clinicopathologic characteristics bwteeen elderly and young and middle-aged patients (according to the standard of 65 years old) were analyzed. At the same time, Cox risk regression model was used to analyze the prognostic factors of elderly patients with TNBC.ResultsA total of 142 patients with TNBC were collected, including 53 elderly patients and 89 young and middle-aged patients. There were no significant differences in terms of family history, histological grade, clinical TNM stage, T stage, axillary lymph node status, and postoperative chemotherapy between the elderly patients and young and middle-aged patients (P>0.05). The rate of breast conserving surgery in the young and middle-aged patients was higher than that in the elderly patients (χ2=4.665, P=0.031). All patients were followed up to 60 months, the recurrence and metastasis rate and the mortality of the elderly patients were lower than those of the young and middle-aged patients (recurrence and metastasis rate: 30.2% versus 47.2%, χ2=3.974, P=0.046; mortality: 11.3% versus 28.1%, χ2=5.474, P=0.019), and the 5-year disease-free survival rate and 5-year overall survival rate of the elderly patients were higher than those of the young and middle-aged patients (5-year disease-free survival rate: 69.8% versus 52.8%, χ2=4.106, P=0.037; 5-year overall survival rate: 88.7% versus 71.9%, χ2=5.209, P=0.022). The tumor T stage (χ2=14.806, P=0.001) and status of axillary lymph node metastasis (χ2=8.149, P=0.043) were associated with postoperative recurrence and metastasis in the elderly patients with TNBC by univariate analysis, and which were the independent risk factors for the recurrence and metastasis in the elderly patients with TNBC by multivariate analysis.ConclusionsPrognosis of elderly patients with TNBC is better than that of young and middle-aged patients. Tumor T stage and axillary lymph node status are independent risk factors affecting prognosis of elderly patients with TNBC.
ObjectiveTo analyze the clinicopathologic characteristics and prognosis of human epidermal growth factor receptor 2 (HER2)-negative breast cancer patients with different expression status of estrogen receptor (ER). MethodsThe patients with HER2-negative breast cancer met the inclusion and exclusion criteria and were treated in the Affiliated Hospital of Southwest Medical University from January 1, 2017 to December 31, 2019 were retrospectively collected, and then were assigned into 3 groups according to the ER expression status: ER-negative (ER expression positive rate <1%) group, ER-low expression (ER expression positive rate 1%–10%) group, and ER expression positive rate >10% group. The differences of clinicopathologic characteristics, therapy, and prognosis among the 3 groups were compared. And the risk factors affecting recurrence and metastasis of patients with ER-low expression were analyzed by Cox proportional hazards regression model. ResultsA total of 610 patients with HER2-negative breast cancer were included in this study, including 130 patients in the ER-negative group, 48 patients in the ER-low expression group, and 432 patients in the ER expression positive rate >10% group. The Bonferroni method was used to correct the test level after pairwise comparison, it was found that the histological grade was later (P<0.001, P=0.023) and the Ki-67 expression was higher (P<0.001, P=0.023) in the ER-negative group and ER-low expression group as compared with the ER expression positive rate >10% group; The proportion of the patients receiving chemotherapy in the ER-negative group was higher than that of the ER expression positive rate >10% group (χ2=10.310, P=0.001), while which had no statistical difference between the ER-low expression group and the ER-negative group or the ER expression positive rate >10% group (Fisher exact probability method, P=1.000; χ2= 3.585, P=0.058); The proportion of patients receiving endocrine therapy in the ER-low expression group was higher than that in the ER-negative group (χ2=36.333, P<0.001) and lower than the ER expression positive rate >10% group (χ2=246.996, P<0.001). The difference in disease-free survival (DFS) curves among 3 groups was statistically significant (χ2=46.805, P<0.001); There were no statistical differences in the overall survival (OS) curve and DFS curve between the ER-negative group and the ER-low expression group (Two stage test, P=0.786; χ2=1.141, P=0.286), and which in the ER expression positive rate >10% group were significantly better than thoses in the ER-negative group (χ2=10.137, P=0.001; χ2=39.344, P<0.001) and the ER-low expression group (χ2=4.075, P=0.044; χ2=31.911, P<0.001). The results of multivariate Cox proportional hazards regression analysis showed that N1 and N2 [N0 as reference: RR (95%CI)=7.740 (1.939, 30.897), P=0.004; RR (95%CI)=9.513 (1.990, 45.478), P=0.005) and T3 [T1 as reference: RR (95%CI)=27.357 (2.188, 342.041), P=0.010] increased the probabilities of recurrence and metastasis HER2-negative breast cancer patients with ER-low expression. ConclusionsAccording to results of this study, patients with HER2-negative breast cancer showed certain differences in histological grade and Ki-67 expression among patients with three different ER expression status, but no statistical difference is found between ER-low expression and ER-negative breast cancer, and the prognoses of both are worse than that of ER expression positive rate >10% breast cancer patients. Lymph node metastasis and larger tumor are risk factors affecting recurrence and metastasis in ER-low expression breast cancer patients.
ObjectiveTo compare the clinicopathological characteristics of breast invasive micropapillary carcinoma (IMPC) with different composition ratios, and analyze the relationship between proportion of micropapillary carcinoma components and the prognosis of IMPC. Methods The related data of 121 patients with invasive ductal carcinoma (IDC) complicated with IMPC who were treated in the Department of Breast Surgery, Affiliated Hospital of Southwest Medical University from August 2016 to August 2020 were collected. With micropapillary carcinoma accounting for 50%, the patients were divided into IMPC <50% group and IMPC ≥50% group. The correlation between related clinicopathological features and prognosis of patients was analyzed. Results There were 85 patients in the IMPC <50% group and 36 patients in the IMPC ≥50% group. The analysis results showed that there was no significant differences between the two groups in menstrual status, histological grade, molecular typing, TNM stage, age, immunohistochemical expression, neoadjuvant therapy, nerve invasion, nipple invasion, and skin invasion (P>0.05). The rate of lymphatic vessel invasion (LVI) in the IMPC ≥50% group was 83.33% (30/36), which was significantly higher than 61.18% (52/85) in the IMPC <50% group, and the difference between the two groups was statistically significant (χ2=5.684, P=0.017). Kaplan-Meier survival curve was drawn, and the analysis results showed that the 3-year cumulative disease-free survival (DFS) of IMPC patients was correlated with the number of lymph node metastasis and LVI (P<0.05). And with the estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, Ki-67, molecular typing, proportion of micropapillary carcinoma components and histological grade were unrelated (P>0.05). The results of multivariate Cox risk regression analysis showed that the number of lymph node metastases and LVI were independent prognostic factors affecting DFS in patients. Conclusions When the proportion of IMPC component is ≥50%, the LVI rate of tumor is higher than that of IMPC component <50%. The number of lymph node metastasis and LVI are independent prognostic factors affecting DFS in IMPC patients.
Objective
To investigate pattern of lymph node metastasis (LNM) in patient with early gastric cancer (EGC) and it’s relation to clinicopathologic features so as to providing evidence for proper clinical management for EGC.
Method
The clinical and pathologic data of 101 EGC patients who were diagnosed and treated in the West China Hospital of Sichuan University from January 2011 to December 2012 were retrospectively analyzed.
Results
The LNM was found in the 28 patients, the rate of the LNM was 27.7% (28/101). In the univariate analysis, the LNM was associated with the macroscopic type (P=0.013), depth of invasion (P<0.001), differentiation type (P=0.044), and lymphovascular invasion (P=0.020); In the multivariate logistic regression analysis, the factors including of the macroscopic type (RR=4.742, P=0.009), differentiation type (RR=6.369, P=0.011), and depth of invasion (RR=15.218, P<0.001) were the independent risk factors for the LNM. Twenty-eight patients with LNM had only 1 positive lymph node, 4 patients had more than 7 positive lymph nodes. The No.6 lymph node was the most frequently involved station (35.7%, 10/28). The LNMs in the 69.7% (19/28) patients were restricted in the extent of the D1 lymphadenectomy, 3 (10.7%) patients without the perigastric lymph node involvement had the No.8a or No.9 LNM.
Conclusion
LNM in patient with EGC is correlated with clinicopathologic features such as macroscopic type, depth of invasion, differentiation type, and lymphovascular, further investigation is warranted to clarify risk factors of LNM in patient with EGC.
