PURPOSE: The American Joint Committee on Cancer 8th edition (AJCC8) prognostic stage (PS) was implemented January 1, 2018, but it is complex due to multiple permutations. A North American group proposed a simpler system using the anatomic stage with a risk score system (RSS) of 1 point each for grade 3 tumor and human epithelial growth factor receptor 2 (HER2) and estrogen receptor (ER) negativity. Here we aimed to evaluate this risk score system with our database of Asian breast cancer patients and compare it against the AJCC8 PS. METHODS: Patients diagnosed with breast cancer stage I–IV in 2006–2012 were identified in the SingHealth Joint Breast Cancer Registry. Five-year breast cancer-specific survival (CSS) and overall survival (OS) were calculated for each anatomic stage according to the risk score and compared with the AJCC8 PS. RESULTS: A total of 6,656 patients were analyzed. The median follow-up was 61 (interquartile range, 37–90) months. There was a high receipt of endocrine therapy (84.6% of ER+ patients), chemotherapy (84.3% of node-positive patients), and trastuzumab (86.0% of HER2+ patients). Within each anatomic stage, there were significant differences in survival in all sub-stages except IIIB. On multivariate analysis, the hazard ratio for negative ER was 1.74 (1.48–2.06), for negative HER2 was 1.49 (1.26–1.74), and for grade 3 was 1.84 (1.55–2.19). On multivariate analysis controlled for age, ethnicity, and receipt of chemotherapy, the RSS (Akaike information criterion [AIC] = 10,649.45; Harrell's Concordance Index [C] = 0.85) was not inferior to the AJCC8 PS (AIC = 10,726.65; C = 0.84) for CSS, nor was the RSS (AIC = 14,714.4; C = 0.82) inferior to the AJCC8 PS (AIC = 14,784.69; C = 0.81) for OS. CONCLUSION: The RSS is comparable to the AJCC8 PS for a patient population receiving chemotherapy as well as endocrine- and HER2-targeted therapy and further stratifies stage IV patients.

OBJECTIVETo study and evaluate the curative effect and mechanism of Qiangxin Granule (QXG) in intervening chronic heart failure (CHF) rats with Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BS-ES).

METHODSTotally 72 SD rats of clean grade were randomly divided to the normal control group (n =10) and the model group (n = 62). The XQD-BS-ES rat model was established by adriamycin plus propylthiouracil method. Survived modeled rats were then randomly divided to 5 groups i.e., the model group (n = 11, administered with normal saline by gastrogavage), the Western medicine (WM) group (n =11 , administered with perindopril and hydrochlorothiazide by gastrogavage), the low dose QXG (QXG(L)) group (n = 11, administered with 9.26 g/kg QXG by gastrogavage), the middle dose QXG (QXG(M)) group (n = 11, administered with 18.52 g/kg QXG by gastrogavage), the high dose QXG (QXG(H)) group (n = 11, administered with 37.04 g/kg QXG by gastrogavage). After 4 weeks of treatment, left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), tri-iodothyronine (T3), tetra-iodothyronine (T4), thyroid stimulating hormone (TSH), as well as heart, lung, liver weight index and their pathological sections, and high sensitivity C-reactive protein (HS-CRP), angiotensin II (Ang II), carbohydrate antigen 125 (CA125) were detected and compared.

RESULTSCompared with the normal control group, LVEF, LVFS, BNP, HR, RR, urine output, ear temperature, EST, T3, T4, TSH, HS-CRP, Ang II, and CA125 changed significantly in the model group (P < 0.01). Compared with the model group after treatment, LVEF, LVFS, BNP, urine output, EST, T4, heart and liver weight index, HS-CRP, Ang II, CA125 were significantly improved in each QXG group (P < 0.05, P < 0.01). Moreover, TSH was improved in the QXGL and QXG(M) groups (P < 0.05); ear temperature and T3 in the QXG(M) were also improved (P < 0.05); the lung weight index decreased in the QXG(M) and QXG(H) groups (P < 0.01). Compared with the WM group, T4 and CA125 were obviously improved in all QXG groups (P < 0.01); BNP and ear temperature were obviously improved in QXG(L) and QXG(M) groups (P < 0.05, P < 0.01); LVEF, LVFS and TSH were obviously improved in the QXG(M) group (P < 0.05, P < 0.01). And as far as each treatment group, LVEF, LVFS, urine output increased significantly after treatment (P < 0.01); EST obviously increased in QXG(M) and QXG(H) groups (P < 0.01); ear temperature increased in all QXG groups (P < 0.05, P < 0.01). Moreover, compared with the model group, pathological changes of heart, lung, and liver were improved to some degree in each treatment group, especially in the QXG(M) group.

CONCLUSIONSGood curative effect was shown in each QXG group. QXG could improve LVEF, LVFS and BNP of CHF rats of XQD-BS-ES, as well as T3, T4, TSH, EST, urine output, and ear temperature. Moreover, QXG showed superiority than WM group in this respect.

OBJECTIVETo establish and evaluate chronic heart failure (CHF) rat model of Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BSES).

METHODSTotally 40 SD rats were randomly divided into the normal control group (Control), the propylthiouracil (PTU) group, the adriamycin (ADR), and the ADR + PTU group. Normal saline was used as equivalent solvent of each group. Rats in the Control group were intragastrically and intraperitoneally injected with normal saline. Rats in the PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with normal saline. Rats in the ADR group were intragastrically injected with ADR solution and intraperitoneally injected with normal saline. And rats in the ADR + PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with ADR solution. The dose of PTU was 0.2% of daily forage weight, once daily. The dose of ADR was 3.5 mg/kg, once per week. The modeling lasted for 6 weeks. Left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), Tri-iodothyronine (T3), tetra-iodothyronine(T4), thyroid stimulating hormone (TSH) as well as heart, lung, liver weight indices and their pathological sections were integrated and compared.

RESULTSCompared with the Control group, LVEF, LVFS, BNP, HR, RR, heart, lung, liver weight indices, urine output, ear temperature, EST, and T3, T4, and TSH changed significantly in the ADR group, the PTU group, and the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure occurred in pathological sections of heart, lung, and liver. Compared with the ADR group, LVEF, LVFS, BNP, and lung, liver weight indices, urine output, ear temperature, T3, T4, and TSH changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were more serious in pathological sections of heart, lung, and liver. Compared with the PTU group, LVEF, LVFS, BNP, HR, RR, urine output, EST, T4, heart and lung weight indices changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were quite serious in pathological sections of heart, lung, and liver.

CONCLUSIONADR + PTU was an appropriate method to establish CHF rat model of XQD-BSES.

OBJECTIVETo summarize the experience of diagnosis and treatment of esophageal leiomyoma.

METHODSClinical data of 52 patients with esophageal leiomyoma were analyzed from 1993 to 2002.

RESULTSAbout 54% patients in this group had difficulty of food intake. The diagnostic accuracy of gastrointestinal barium meal series, computed tomography, gastric endoscope and endoscopic ultrasonography (EUS) for esophageal leiomyoma was 64% 44% 27% and 90% respectively. All patients received operation, resection of esophageal leiomyoma by videothoracoscopy (VAS) and endoscope were performed in 6, 9 patients respectively. The remaining 37 patients received regular open operation,in whom 32 cases received enucleation of esophageal leiomyoma, 5 cases received partial esophageal resection and esophageal-gastric anastomosis. No serious complications occurred except only one case needed operation again because of bleeding.

CONCLUSIONEUS is an effective method for diagnosing esophageal leiomyoma. VAS and endoscopic treatment should be considered for suitable cases in order to reduce the trauma.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome among Kazakh and Han ethnicities in Xinjiang.Methods PCR-RFLP was used to detect 802 subjects' lipoprotein lipase Hind Ⅲ and S447Xgenotypes (including 201 controls and 200 metabolic syndrome patients in Kazakh and Han ethnicities, respectively). Results (1) Frequencies of H + H-/H-H- genotype (32.50% vs.47.76%), H- allele( 18.00% vs. 28.86%), SX/XX genotype (8.00% vs. 22.39%) and X allele (4.00%vs. 12.44% ) for metabolic syndrome in Hah ethnicity were all significantly lower than those in controls (P＜ 0.01 ). (2) The frequencies of H + H-/H-H- genotype (33.50% vs. 46.80% ), H- allele (22.00% vs. 28.60%), SX/XX genotype (10.50% vs. 22.90%) and X allele (5.50% vs. 12.44% ) in patients with metabolic syndrome in Kazakh were all significantly lower than those for controls (P＜0.01). (3) The frequencies of lipoprotein lipase gene Hind Ⅲ and S447X genotypes and alleles in Kazakh were not significantly different from Han (all P＞0.05). (4)The levels of waist circumference, systolic blood pressure, diastolic blood pressure, triglyceride and FPG in H + H-/H-H- and SX/XX genotype were significantly lower than those in H + H + and SS genotype.HDL-C was significantly higher than that in H + H + and SS genotype (P＜0.05). (5) The frequencies of H + H + and SS genotype increased along with the increase in number of metabolic syndrome component. Conclusion The lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms were associated with metabolic syndrome risk in Kazakh, and H + H-/H-H- genotype, H- allele, SX/XX genotype and X allele might have served as protective factors of metabolic syndrome. H + H-/H-H- and SX/XX genotype seemed to have had beneficial effects for all the metabolic syndrome components, and the frequencies of H + H + and SS genotype were increasing along with the increase of number in the metabolic syndrome components.

Purpose The clinical and dual-layer detector spectral CT(DLCT)features of epidermal growth factor receptor(EGFR)mutation and anaplastic lymphoma kinase(ALK)rearrangement of lung adenocarcinoma were studied by DLCT multi-parameter imaging to explore a non-invasive prediction method for clinical diagnosis of lung adenocarcinoma gene expression.Materials and Methods A total of 98 cases of lung adenocarcinoma diagnosed by pathology in Gansu Provincial Hospital were prospectively collected from August 2020 to March 2022.Clinical parameters(gender,age,lesion morphology,number,mediastinal lymph node metastasis,EGFR and ALK mutations status)and DLCT parameters including slope of the spectrum curve of the arteriovenous phase(λHUA,λHUv),the standard iodine concentration of the arteriovenous phase(NICA,NICv),the 40 keV single-energy CT value of the arteriovenous phase(CTA 40 keV,CTv 40 keV),the active atomic number of the arteriovenous phases were collected,respectively.According to the expression of EGFR and ALK,all patients were divided into three groups:EGFR mutant group[EGFR(+)],ALK rearrangement group[ALK(+)],EGFR/ALK both negative group[EGFR/ALK(-)].Clinical and DLCT parameters of each group were analyzed.Results There were statistical difference in gender between the EGFR(+)group and EGFR/ALK(-)group(x2=11.010,P＜0.05).There were statistical differences in lesion morphology among the three groups(x2=12.858,P＜0.05).The value of CTv 40 keV in the EGFR(+)group was significantly higher than that in EGFR/ALK(-)group(t=1.997,P＜0.05),and the NICv in the ALK(+)group was significantly lower than that in EGFR/ALK(-)group(t=2.155,P＜0.05).The λHUv,NICv,CTv 40 keV of EGFR(+)group were significantly higher than those of ALK(+)group(t=2.613,3.149,3.218,all P＜0.05).The sensitivity and specifiicity to identify EGFR(+)and EGFR/ALK(-)adenocarcinoma were 62.7％and 70.0％,the area under curve(AUC)was 0.634(95％CI 0.516-0.756)when the CTv 40 keV value was 141.070 Hu.The sensitivity and specificity to identify ALK(+)and EGFR/ALK(-)adenocarcinoma were 76.7％and 64.2％,the AUC was 0.706(95％CI 0.536-0.853)when NICv value was 0.287.The sensitivity to identify EGFR(+)and ALK(+)adenocarcinoma were 70.6％,64.7％,72.5％and the specificity was 76.5％,76.5％,82.4％,respectively,the AUC was 0.734(95％CI 0.606-0.829),0.751(95％CI 0.610-0.832),0.773(95％CI 0.649-0.861)when the values of λHUv,NICv and CTv 40 keV were 1.335,0.320 and 132.350,respectively.Delong test showed that the AUC of CTv 40 keV and λHUv was statistically different(Z=2.327,P＜0.05),and the AUC of CTv 40 keV was 0.773.Conclusion The gender,lesion morphology and DLCT parameters(λHUv,CTv 40 keV,NICv)of lung adenocarcinoma have certain predictive value for EGFR and ALK genetic expression,which can help clinical judgment of lung adenocarcinoma gene mutation pattern.

OBJECTIVETo evaluate prognostic factors in patients with stage IB-IIA of cervical carcinoma treated by surgery.

METHODSBetween December 1992 and December 2001, 111 patients with stage IB-IIA cervical cancer surgically treated were analyzed. Median age 40 years. According to 1994 FIGO Staging System: IB 80 (IB1 40, IB2 40) and IIA 31. There were 93 cases of squamous cell carcinoma (83.5%), 17 cases of adenocarcinoma (15.3%) and one case of small cell carcinoma. All patients were treated by radical hysterectomy and pelvic lymphadenectomy, 74 patients had preoperative adjuvant radiotherapy, 24 patients had postoperative adjuvant treatment. Kaplan-Meier method was used to evaluate the survival, the related prognostic factors were assessed by Cox regression and chi(2) test.

RESULTSThe overall 5-year survival rate was 85.9%, being 89.1%, 90.7% and 78.4% for stage IB1, IB2 and IIA, respectively. Univariate analysis showed that tumor size (hazards ratio [HR] = 1.479, P = 0.152), tumor type (HR = 1.440, P = 0.264), clinical stage (HR = 1.380, P = 0.354), adjuvant treatment (HR = 1.210, P = 0.450), lymph node metastasis (HR = 1.432, P = 0.540), endocervical involvement (HR = 2.244, P = 0.036), depth of myometrial invasion (HR = 3.295, P = 0.06) and multiple sexual partners during pregnancy (HR = 10.172, P = 0.000) were of prognostic significance. The latter two were the most important factors indicative of poor prognosis.

CONCLUSIONThe depth of myometrial invasion and multi-partners combined with pregnancy are closely related to the prognosis while the pre- and/or postoperative adjuvant therapy should be considered for stage IB-IIA cervical cancer with deep myometrial invasion and in pregnant patients with multiple sexual partners.
