ABSTRACT
Background and Objectives: - Carcinoma Breast is most common malignancy in females in USA and second among cases deaths in females (after lung cancer). There is considerable geographic , ethnic and racial variability in Breast cancer in evidence with about 5 fold variation throughout the world. Triple negative breast cancer is a heterogonous disease diagnosed by Immune Histo Chemistry (IHC).Triple Negative Breast cancer is characterized by tumor that do not express ER or PR and HER2neu . Proto typical Triple Negative Brest cancer is aggressive in nature and associate with poor prognosis. The Objectives of this study is to analyse the clinical and Pathological features of Triple Negative Breast Cancer and compare the result with similar studies in literature. Fifty Methods:- cases Triple negative Breast Cancer were included in this study. Clinical and pathological features and treatment were noted. Incidence Result:- of Triple Negative Breast Cancer was 35%. The median age of presentation was 45yrs. There were 4% males Triple negative Breast cancer cases out of female patients, most of patients were Pre (or) Perimenopausal(65%). 4% patients had family history of malignantly. Most common stage of presentation was stage III (46%). In Stage IV, Lung and bone metastasis was common. Ten Patients received Neoadjuvant chemo therapy (NACJ) and disease progressed in 4% while on Neoadjuvant chemotherapy, Even though 45 patients had surgery only 34 were eligible to received Adjuvant Radiotherapy. Total of 18% Patients had either progressive disease while on treatment (8%) (or) recurrence 10%. Eighteen percent patients died due to the disease. 33% patients on follow up. There were more Invasive Duct Cell carcinoma (IDCC) cases with medullary differentiations (or) Purse medullary Carcinomas (12%). No deaths Occur in the medullary variants TNBC. Majority of the tumor were high grade margins were negative in most of the cases. Incidence of Tri Inclusion:- ple negative breast cases was higher than western literature but comparable to Indian Studies. The age of Presentation was about 10 years younger than western data. Triple Negative Breast cancer was more common in young, pre (or) perimenopausal women. Small number of patients had family history, majority were state II (or) III. There was high number of progressive disease, recurrence and death while on the study (or) within less than 1 yr of treatment. Triple Negative Breast cancer is very aggressive disease with relatively better prognosis in the medullary variant Triple Negative Breast Cancer.
ABSTRACT
:To explore the value of quantitative perfusion histogram parameters of dynamic contrast-enhanced magnetic resonance imaging （DCE-MRI） in pathological classification of uterine leiomyoma and its correlation with Ki-67 protein expression. Thirty five patients with uterine leiomyoma confirmed by operation and pathology at Shaoxing People's Hospital from October 2015 to September 2017 were analyzed retrospectively，including 15 cases of ordinary type，8 cases of cellular type and 12 cases of degenerative type. All patients were examined by pelvic DCE-MRI before operation，and the histogram parameters （median，mean，skewness，kurtosis，energy，entropy） of various quantitative perfusion parameters，including volume transport constant （K），rate constant （K），extravascular extracellular space distribute volume per unit tissue volume （V），blood plasma volume per unit volume of tissue （V） were calculated，and the efficacy of different parameters in pathological classification of uterine leiomyoma was evaluated by ROC curve. The expression of Ki-67 protein in uterine leiomyoma was detected by immunohistochemical method，and the correlation between histogram parameters and Ki-67 protein expression was analyzed by Pearson and Spearman correlation analysis. The median and mean values of K，K，V and V in the cellular group were higher than those in the degenerative group and the ordinary group（<0.05 or <0.01），while the skewness of V，the skewness and kurtosis of K in the cellular group were lower than those in the ordinary group （all <0.05）. The entropy of K in the cellular group was higher than that in the degenerative group and the ordinary group （all < 0.05）. The entropy of V in the cellular group was higher than that in the ordinary group （<0.01）. The median，mean，skewness of K，median and mean of K，median and mean of V，median，mean，energy and entropy of V were correlated with Ki-67 expression（all <0.05）. The results of ROC curve analysis showed that the median threshold of K was 0.994/min，the sensitivity and specificity for the diagnosis of cellular uterine leiomyoma were 100.0% and 77.8% respectively，and the area under the ROC curve was 0.949. When the mean threshold of K was 1.170/min，the sensitivity and specificity for diagnosing cellular uterine leiomyoma were 100.0% and 77.8% respectively，and the area under the ROC curve was 0.958. The area under the ROC curve of K （entropy），K （median，mean），V （median，mean，entropy） in the diagnosis of cellular uterine leiomyoma were 0.755-0.907. :DCE-MRI quantitative perfusion histogram parameters have high diagnostic value in differentiating pathological types of uterine leiomyoma，especially for cellular uterine leiomyoma.

@#Objective To summarize the pathological characteristics of primary left ventricular tumors and their influence on surgical treatment. Methods The clinical data of 32 patients with primary left ventricular tumor in Fuwai Hospital from January 2008 to March 2019 were retrospectively analyzed, including 17 males and 15 females with an average age of 33.88±17.89 years. The impact of different types of left ventricular tumor pathology on the surgical outcome was analyzed. Results Thirty-two patients with primary left ventricular tumors underwent surgery. Postoperative pathological biopsy results revealed benign tumor in 31 patients, including myxoma in 10 patients, lipomas in 7 patients, fibroma in 4 patients, hemangioma in 3 patients, rhabdomyoma in 2 patients, cyst in 2 patients, schwannoma in 1 patient, papillary fibroelastoma in 1 patient, cavernous hyperplasia of valvular lymphatic vessels in 1 patient. There was 1 patient of carcinoid (low-grade malignant tumor). Thirty patients underwent tumor resection surgery under hypothermic anesthesia and cardiopulmonary bypass followed by cardiac arrest while 2 patients without cardiopulmonary bypass. Nine patients received partial resection of the tumor, including lipomas in 6 patients, rhabdomyoma in 2 patients, schwannoma in 1 patient. Twenty-three patients received complete resection of the tumor. There were no in-hospital deaths, bleeding, secondary thoracotomy, low cardiac output, renal failure, postoperative embolism or other surgical complications. All the patients were normal before they were discharged out of the hospital. Their average postoperative hospital stay was 8.1±2.7 d. Within 6 months after the surgery, all 32 patients returned to the hospital for reexamination, and ultrasound results were all normal. Afterwards, the patients were followed up by telephone or in an outpatient clinic, and 3 patients were lost. The follow-up rate was 90.63%. During the follow-up of 3-120 (61.4±38.5) months, among the 9 patients whose tumors were partially resection, 2 patients recurred. One patient with schwannoma recurred 30 months after the surgery, and in the other patient lipomas grew 15 months later which resulted in massive regurgitation of the mitral valve. Conclusion Surgical resection is the first choice for the treatment of left ventricular benign tumors. For malignant left ventricular tumors, it is necessary to be cautious, and the surgical risk needs to be carefully evaluated. Most of the primary left ventricular tumors need to be operated as soon as possible. A surgeon should develop different surgical strategies according to different pathological types of tumors.
ABSTRACT
Objective To compare the different pathological type of renal tumor,clinical epidemiology,imaging and pathological features,summarize its value in the diagnosis of renal tumor.Methods The clinical data of 2198 patients who underwent surgical treatment in our hospital due to renal tumors from January 2010 to January 2019 were retrospectively analyzed.There were 1 404 males and 794 females with an average age of (56.5 ± 11.7) years old.The clinical epidemiology,image features and pathological features were compared.Results Among them,the pathological results concluded 1 891 cases of renal clear cell carcinoma (86.0％),112 cases of papillary renal cell carcinoma (5.1％),76 cases of chromophobe cell carcinoma (3.5％),23 cases of multilocular cystic renal tumors with low malignant potential (1.0％),13 cases of Xp11.2 translocation carcinoma (0.6％),4 cases of collecting duct carcinoma (0.2％),58 cases of anadipotic angiomyolipoma (2.6％),18 cases of acidophiloma (0.8％),and 3 cases of metanephric adenoma (0.1％).The overall differences in age and gender among patients with renal tumors of different pathological types were statistically significant (F =13.8,P ＜ 0.05;x2 =20.5,P ＜ 0.05),Xpl 1.2-translocated carcinoma had the lowest mean age of onset,which was (44.9 ± 17.1 years old).The percentage of women with anadipotic angiomyolipoma was higher (41,70.7％),and the percentage of men with clear cell carcinoma and papillary renal cell carcinoma was higher (1 253,66.3％) and(77,68.8％).There was no statistically significant difference in side sex and clinical manifestations among patients with different pathological types of renal tumors (x2 =16.27,P ＞ 0.05).No significant difference in the distribution of left and right side,the clinical manifestations were mainly sporadic (x2 =19.63,P ＞ 0.05).The results of renal tumors ultrasound ith different pathological types showed statistically significant difference (x2 =67.l,P ＜ 0.05).Hyperechoic (20,34.5％) and mixed echogenicity (16,27.6％) were the main manifestations of lipoma.Multilocular cystic renal tumors with low malignant potential were mostly cystic and solid mixed echogenicity (14,60.9％).CT values of renal tumors of different pathological types at all stages showed statistically significant differences (P ＜ 0.05).The CT values of clear cell carcinoma at the arterial phase of CT enhanced scan were significantly higher than those of other types of tumors (F =11.6,P ＜ 0.05),but decreased significantly in the parenchymal phase,showing the enhancement characteristics of "fast in and fast out".The CT values of papillary cell carcinoma in the third phase of enhanced scan were all lower than those of clear cell carcinoma and chromophobe cell carcinoma (P ＜ 0.05),showing a "progressive enhancement".The enhancement effect of chromophobe cell carcinoma is somewhere in between.The CT value on plain scan of anadipotic angiomyolipoma was higher than that of clear cell carcinoma,and the enhancement was followed by continuous enhancement,showing the characteristics of "fast in and slow out".The majority of clear cell carcinoma and papillary cell carcinoma were tan section (1 235,72.55％;51,52.13％).The grey-white section was the most common type of adipogenic angiomyolipoma (21,40.4％).Conclusions The epidemiological characteristics,imaging and pathological features of renal tumors of different pathological types have certain characteristics,especially the enhanced CT features of renal clear cell carcinoma,papillary renal cell carcinoma,chromophobe cell carcinoma and anadipotic angiomyolipoma,which are of certain value for the differential diagnosis of renal tumors of different pathological types.
ABSTRACT
Objective To study the component ratios of pancreatic carcinoma,and prognosis of patients with the different pathological types.Methods The data of 92 011 pancreatic carcinoma patients who were diagnosed by the definite pathological method from 2004 to 2014 were extracted from the US SEER database.The life table was used to calculate the 1-,3-and 5-year survival rates.The Kaplan-Meier was used to construct the survival curves of the patients.The Cox univariate analysis was applied to evaluate the HR of the different pathological types,and the x2 test and independent sample t-test were used to evaluate the base line data.Results The overall 5-year survival of 92 011 pancreatic carcinoma patients was 7.6％.The median survival time was 8.8 months and the component ratios of the pancreatic ductal adenocarcinoma (PDAC),pancreatic epithelium cancer bedside the PDAC,neuroendocrine tumors,undifferentiated carcinoma,mesenchymal carcinoma and rare cancer unclassified were 85.78％,6.40％,6.67％,0.97％,0.10％ and 0.08％,respectively.The differences were statistically significant between the baseline data such as age,gender,race and position (P ＜ 0.05).The overall 5-year survivals of the PDAC,pancreaticepithelium cancer beside the PDAC,neuroendocrine tumors,undifferentiated carcinoma,mesenchymal carcinoma and rare cancer unclassified were 4.2％,13.4％,49.2％,5.0％,29.2％ and 24.5％,respectively,and the median survival times were 5 months,7 months,58 months,2 months,26 months and 7 months respectively.The distant metastasis rate of neuroendocrine carcinoma was the lowest (35.0％).The undifferentiated carcinoma was the most prone to distant metastases (65.2％).Basically,half of the other types of pancreatic cancer had metastasis at the time of diagnosis.In pancreatic epithelium cancer beside the PDAC,the high to low 5-year survival rates were solid pseudopapillary carcinoma (87.3％),cystadenocarcinoma (36.8％),intraductal papillary mucinous neoplasm (36.5％),acinar cell carcinoma (20.0％),and pancreatic adenocarcinoma mixed with other subtypes (19.7％).The incidence of the other types of pancreatic carcinoma was less than 8％,such as mucinous carcinoma,squamous cell carcinoma,adenosquamous carcinoma and signet ring cell carcinoma.In neuroendocrine tumor,the 5-year survival rate of insulinoma (77.1％) was higher than those of neuroendocrine tumor (malignant) (NET,62.0％) and neuroendocrine carcinoma (NEC,46.5％).Conclusion The prognosis of pancreatic carcinoma was poor,and the pathological types had a significant impact on the prognosis of the patients.
ABSTRACT
Objective To analyze the distribution of body mass index (BMI) in the patients with thyroid cancer. Methods The clinical data of 1 005 cases of thyroid cancer diagnosed by the postoperative pathology from January 2007 to October 2017 in Xinjiang Military Region General Hospital were retrospectively analyzed. A total of 668 healthy people who underwent ulltrasonic and functional test of thyroid cancer without obvious abnormal response were chosen as healthy controls. The preoperative BMI of thyroid cancer patients and BMI distribution of healthy controls were compared. Results According to the BMI Asia criteria, 1 005 patients with thyroid cancer included 346 (34.43 %) cases of obesity, 296 (29.45 %)normal cases, 275 (27.36 %) chubby cases, 60 (5.97 %) cases of severe obesity, 28 lean cases and the obese people were the most. Among 668 healthy controls, 269 (40.27 %) cases were normal, 168 (25.15 %) cases were chubby, 165 (24.70 %) cases were obesity, and 41 (6.14 %) cases were lean, 25 (3.74 %) cases were severe obesity and the most common was the normal group. There was a statistically significant difference of BMI distribution between the two groups in the lean, normal, obesity, and severe obesity group (χ2= 11.400, P = 0.001; χ 2= 20.991, P = 0.000; χ 2= 17.898, P = 0.000; χ 2= 4.129, P = 0.042). The pathological types of 1005 cases of thyroid cancer were mainly papillary carcinoma [948 cases (94.33 %)], successively followed by follicular carcinoma [42 cases (4.18 %)], medullary carcinoma [9 cases (0.90 %)] and undifferentiated carcinoma [6 cases (0.60 %)]. Patients with papillary carcinoma included 321 (33.86 %) obese cases, 282 (29.75 %) normal cases, 264 (27.85 %) chubby cases, 57 (6.01 %) cases of severe obesity, and 24 (2.53 %) lean cases. Patients with follicular carcinoma included 19 cases (45.24 %) obese cases, 9 (21.43 %) normal cases, 7 (16.67 %) chubby cases, 4 (9.52 %) lean cases, and 3 (7.14 %) cases of severe obesity; Patients with medullary carcinoma included 4 obese cases, 3 chubby cases, and 2 normal cases; Patients with undifferentiated cancer included 3 normal cases, 2 obese cases, and 1 chubby case. There was no significant difference in BMI distribution among different pathological types of thyroid cancer patients (all P＞ 0.05). Conclusions The number of obesity and severe obesity in thyroid cancer patients is more than that in healthy people, while the number of lean and normal groups is less than that in healthy controls. Obesity may be related with thyroid cancer, which contributes to the risk assessment and prevention of thyroid cancer.

Objective:To explore the mRNA differential expression and clinical effect of leptin in different kinds of ovarian cancer.Methods: 129 patients with ovarian cancer and 42 controls were collected from Jun.2015 to Jun.2016 in our hospital.We got a small tissue by ovarian biopsy guided under the ultrasonic processing,detected the total RNA,purified mRNA and analyzed the correlation of the expression of leptin in different kinds and clinical stages of ovarian cancer.Results: Compared with the control groups,the mRNA expression of leptin in each group was increased(P<0.05),and the serous adenocarcinoma group increased obviously(P<0.05).Patients with clinical stage FIGO Ⅲ was significantly higher than other stages in serous adenocarcinoma group(P<0.05).Conclusion: Leptin could express in different kinds and clinical stages of ovarian cancer,and may be a new detection index for early diagnosis of ovarian cancer.
ABSTRACT
Objective To investigate the relationship between ischemic time and thrombus types in patients with ST-segment elevation myocardial infarction (STEMI).Methods Eighty-two STEMI patients undergone emergency percutaneous coronary intervention (PCI) and coronary thrombus aspiration (CTA) from Sep.2012 to Apr.2016 were included and divided into 3 groups according to the ischemic time:≤4 hours (n=36),4-7 hours (n=30) and ＞7 hours (n=16).Visible aspirated thrombi were collected and separated into erythrocyte-rich type,platelet/fibrin-rich type and combined type thrombi by HE dying.The percentage difference of the 3 types thrombi was compared among the 3 groups.Results The percentage of platelet/fibrinrich type,erythrocyte-rich type and combined type thrombi in the 3 groups were as follows:in ≤4h group:61.1％(22/36),8.3％(3/36) and 30.6％(11/36),P=0.019;in 4-7h group:23.3％(7/30),10.0％(3/30) and 66.7％(20/30),P=0.012;and in ＞7h group:43.8％(7/16),12.5％(2/16) and 43.8％(7/16),P=0.913.For platelet/fibrin-rich type thrombi,the percentages in 3 periods were 61.1％(22/36),19.4％(7/36) and 19.4％(7/36),P=0.009;For combined type thrombi,the percentages in 3 periods were 28.9％(11/38),52.6％(20/38) and 18.4％(7/38),P=0.013;For erythrocyte-rich type thrombi,the percentages in 3 periods were 37.5％(3/8),37.5％(3/8) and 25.0％(2/8),P=0.895.Conclusions The types of intracoronary aspirated thrombi differ from various periods.Ischemia time may be an important predicted factor.
ABSTRACT
Objective To investigate the relationship between pathological types of intracoronary thrombus and changes of ST segment in patients with acute myocardial infarction. Methods Thrombus aspiration during primary PCI was performed in 65 ST-elevation myocardial infarction (STEMI) patients and 42 non-ST-elevation myocardial infarction (NSTEMI) patients. Pathological analysis on thrombosis was made. Results Thrombi characteristics were collected from 48 STEMI patients and 12 NSTEMI patients. In the STEMI group, 39(81.3%) red/mixed thrombus and 9(18.7%) white thrombus were found. While in the NSTEMI group, 8(66.7%) white thrombus and 4(33.3%) red/mixed thrombus were obtained. Conclusions There are both red/mixed and white thrombus in the two kinds of acute myocardial infarction. A variety of elements, including thrombus formation, could contributes to the change of ST in electrocardiograph during acute myocardial infarction.
ABSTRACT
Objective To analyze the status quo of the diagnosis and treatments of primary gastro-intestinal lymphoma (PGIL) in order to improve it. Methods Eighty-one patients with PGIL were ana-lyzed retrospectively including clinical manifestations, endoscopic features, pathological features, HP in-fection, treatment, and prognosis. Results The age of patients with gastric lymphoma was (52.84±15.33) years. The age of patients with intestinal lymphoma was (42.09±15.28) years. Common symp-toms included abdominal pain (76.5%), gastrointestinal bleeding (55.6%), anemia (54.3%), abdominal mass (25.9%), hypoproteinemia (40.7%), bowel obstruction (11.1%), abdominal dis-tension, vomiting, and other non-specific gastrointestinal symptoms (32.1%), weight loss (33.3%); fever (8.6%), diarrhea (7.4%), digestive tract perforation (1.2%), constipation (1.2%), and dysphagia (1.2%). Endoscopic appearances were as follows: tumor type (67.7%), ulcer type (27.7%), and diffuse type (4.6%). Clinical diagnosis rate and endoscopic biopsy confirmation rate were 30.9% and 73.8%. MALT lymphoma accounted for 61.7% of the patients. HP detection rate was 39.5 % and positive rate was 37.5 %. A total of 69 patients received surgeries: 3 had preoperative chem-otherapy, and 34 had postoperative chemotherapy. Twelve patients had non-surgical treatment, 6 patients of whom had simple chemotherapy and HP eradication therapy, and the other 6 gave up during the treat-ment. There was no significant difference in the survival rate of Stage Ⅰ～Ⅱ patients in the surgery alone group, surgery plus chemotherapy group, and chemotherapy and HP eradication therapy group (P>0.05). The survival rate of Stage IIIⅢ～Ⅳ patients in the surgery alone group was lower than that in the other 2 groups (P<0.05). The 5-year, 3-year, and 1-year survival rate was 55.87%, 70.96%, and 96.39%, respectively. Conclusion There are no specific clinical and endoscopic features in PGIL, so the misdiagnosis rate is high. Multi-site biopsy or repeated biopsies and immunohistochemical methods can be used to raise the pathological diagnosis rate. Chemotherapy and HP eradication are recommended.
