RESUMO

Objective To evaluate the application value of abbreviated comprehensive geriatric assessment(aCGA)in elderly female breast cancer patients. Methods Eight aspects of the traditional CGA were simplified to form the aCGA assessment table,based on which the patients were classified into three grades of A,B and C according to the total scores.This study enrolled the elderly female patients with breast cancer aged 70 years and above who were treated in PUMC Hospital from June 2018 to January 2020.Eastern Cooperative Oncology Group(ECOG)scoring and aCGA grading were performed respectively,and the results of the two methods were compared. Results Of the 162 patients,111(68.5%)were classified by the aGGA method as grade A,43(26.5%)as grade B,and 8(5.0%)as grade C;131(80.9%)cases have concurrent diseases,and the most common complications were hypertension(n=89),cardiovascular diseases(n=47)and diabetes mellitus(n=39).The ECOG score was 0-1 in 133(82.0%)cases,2 in 24(14.8%)cases and 3 in 5(3.2%)cases.The ECOG score showed 133(82.0%)cases with good status and 29 cases with poor status.However,according to the aCGA classification,111 cases were in good health status and 51 cases were in poor health status;the difference in the result between the two groups was statistically significant(χ 2=14.24,P<0.001).Conclusion Compared with ECOG score,aCGA grading can more comprehensively evaluate the health status of elderly female breast cancer patients and can be applied to the patients aged 70 and above.

RESUMO

BACKGROUND: Triple-negative breast cancer (TNBC) is one of the most aggressive subtypes of breast cancer and the major phenotype of BRCA related hereditary breast cancer. Platinum is a promising chemotherapeutic agent for TNBC. However, its efficacy for breast cancer with BRCA germline mutation remains inconclusive. Here we present a meta-analysis to evaluate the effect of platinum agents for breast cancer patients with BRCA mutation in neoadjuvant setting. MATERIALS AND METHODS: Pubmed, Embase, and Cochrane Central Register of Controlled Trials databases were searched for relevant studies on neoadjuvant platinum treatment and BRCA related breast cancer. Fixed- and random-effect models were adopted for meta-analyses. Heterogeneity investigation was conducted by sensitivity and subgroup analyses. Publication bias was evaluated by funnel plot and Begg's test. RESULTS: In all, five studies with 363 patients were included for meta-analysis. The pooled pathological complete response (pCR) rates were 43.4% (59/136) and 33.9% (77/227) for platinum and control groups, respectively. Adding platinum to neoadjuvant regimen did not significantly improved pCR rate (odds ratio [OR]: 1.340, 95% confidence interval [CI] = 0.677-2.653, p = 0.400). Sensitivity analyses also revealed platinum did not significantly increase pCR rate in either TNBC or HER2- patients (TNBC subgroup: OR: 1.028, 95% CI = 0.779-1.356, p = 0.846; HER2- subgroup: OR: 0.935, 95% CI = 0.716-1.221, p = 0.622). CONCLUSIONS: Our meta-analysis suggested that the addition of platinum to neoadjuvant chemotherapy did not significantly improve pCR rate for patients with BRCA mutations. Further large-scale randomized control trial with survival data may provide more robust evidence on therapeutic value of platinum for breast cancer neoadjuvant treatment.

RESUMO

BACKGROUND: BRCA1/2 mutation is associated with a high risk of breast cancer, which may preclude breast cancer patients with BRCA1/2 mutation from breast-conserving therapy (BCT) [breast-conserving surgery (BCS), followed by radiotherapy, BCT]. It is debatable whether BCT could be a rational choice for Chinese breast cancer patients with a BRCA1/2 mutation. METHODS: The study comprised a cohort of women with invasive breast cancer either receiving BCT or mastectomy following the criteria for the germline BRCA1/2 mutation test. Germline DNA for BRCA1/2 testing was derived from blood samples. Survival analyses were performed. The correlations were analyzed between survival and distinct types of surgery. To compare the survival between different surgical management, Kaplan-Meier univariate analysis and multivariate Cox regression was used. RESULTS: In BRCA1/2 mutation carriers (N=176) and noncarriers (N=293), 25% and 27.3% of the patients received BCT, respectively (P=0.675). Patients receiving mastectomy (without radiotherapy or followed by radiotherapy) have larger tumor size (P<0.05 both in BRCA1/2 mutation carriers and noncarriers), prognostically worse tumor characteristics including significantly more advanced TNM stage (P=0.017 and P<0.0001 respectively) and more positive lymph nodes (P=0.008 and P<0.0001, respectively) both in BRCA1/2 mutation carriers and noncarriers. Still, more often received systemic therapy has also been observed. After adjustment for clinical-pathological characteristics and systemic treatment, patients who received BCT had a similar breast cancer disease-free survival compared with patients who received mastectomy, both in BRCA1/2 mutation carriers and noncarriers [HR BRCA1/2 =1.17, confidence interval (CI): 0.57-2.39, P=0.68; HRnoncarriers =0.91, CI: 0.47-1.77, P=0.79, respectively). The recurrence free survival after BCT did not differ from mastectomy in BRCA1/2 mutation carriers [BCT, 5-year cumulative recurrence-free survival (RFS) =0.95, CI: 0.89-1.00; mastectomy, 5-year cumulative RFS =0.93, CI: 0.85-1.00], even better for BCT in noncarriers (BCT, 5-year cumulative RFS =0.67, CI: 0.42-0.89; mastectomy, 5-year cumulative RFS =0.83, CI: 0.71-0.95). CONCLUSIONS: Thus, BCT may be a safe and rational choice for Chinese female breast cancer patients with a BRCA1/2 mutation. However, tumor size, the TNM stage, the number of positive lymph nodes, might be taken into consideration when choosing surgical management.

RESUMO

BACKGROUND: The incidence of bilateral breast cancer (BBC) is increasing nowadays comprising 2%-11% of all breast cancer (BC). According to the interval time between the first and second cancer, BBC could be divided into synchronous (SBBC) and metachronous (MBBC). However, this interval time is quite different across studies. It remains controversial whether the survival of BBC, SBBC, and MBBC is similar or worse compared to that of unilateral breast cancer (UBC), and whether the survival of SBBC is similar or worse compared to MBBC. To better understand the survival of UBC, BBC, SBBC, and MBBC and how the interval time would influence the prognosis of SBBC and MBBC, we performed this meta-analysis on studies from recent 10 years (2008-2018). METHODS: Databases of PubMed, Embase, and Web of Science were searched for relevant studies within recent 10 years. Hazard ratio (HR) was adopted to evaluate the difference of overall survival (OS) of UBC, BBC, SBBC, and MBBC. HR of OS comparisons were performed between BBC vs UBC, SBBC vs UBC, MBBC vs UBC, and SBBC vs MBBC with 3, 6, 12 months as the interval time, respectively. RESULTS: There were 15 studies of 72 302 UBC and 2912 BBC included in the meta-analysis. The summary HR of OS comparison between BBC vs UBC was 1.68 (95% CI: 1.28-2.20), SBBC vs UBC was 2.01 (95% CI: 1.14-3.55), MBBC vs UBC was 3.22 (95% CI: 0.75-13.78). When 3, 6, 12 months were used as the interval time, the summary HR of the OS comparison between of SBBC vs MBBC were 0.64 (95% CI: 0.44-0.94), 1.17 (95% CI: 0.84-1.63) and 1.45 (95% CI: 1.10-1.92), respectively. CONCLUSION: BBC and SBBC showed worse prognosis in terms of OS compared to UBC while MBBC manifested similar or non-superior survival as UBC. The OS comparison between SBBC and MBBC changed with different interval time used. The longer the interval time used, the worse the survival of SBBC. SBBC with interval of 3-12 months between the two cancers had the worst prognosis. When 6 months was used to differentiate SBBC from MBBC, these two clinical entities showed similar OS.

RESUMO

AIM: To evaluate the effectiveness and safety of combined ursodeoxycholic acid and percutaneous transhepatic balloon dilation for management of gallstones after expulsion of common bile duct (CBD) stones. METHODS: From April 2014 to May 2016, 15 consecutive patients (6 men and 9 women) aged 45-86 (mean, 69.07 ± 9.91) years suffering from CBD stones associated with gallstones were evaluated. Good gallbladder contraction function was confirmed by type B ultrasonography. Dilation of the CBD and cystic duct was detected. Percutaneous transhepatic balloon dilation of the papilla was performed, ursodeoxycholic acid was administered, and all patients had a high-fat diet. All subjects underwent repeated cholangiography, and percutaneous transhepatic removal was carried out in patients with secondary CBD stones originating from the gallbladder. RESULTS: All patients underwent percutaneous transhepatic balloon dilation with a primary success rate of 100%. The combined therapy was successful in 86.7% of patients with concomitant CBD stones and gallstones. No remaining stones were detected in the gallbladder. Transient adverse events include abdominal pain (n = 1), abdominal distension (n = 1), and fever (n = 1). Complications were treated successfully via nonsurgical management without long-term complications. No procedure-related mortality occurred. CONCLUSION: For patients with concomitant CBD stones and gallstones, after percutaneous transhepatic removal of primary CBD stones, oral ursodeoxycholic acid and a high-fat diet followed by percutaneous transhepatic removal of secondary CBD stones appear to be a feasible and effective option for management of gallstones.

RESUMO

BACKGROUND: Mammography screening usually detects low-risk breast cancer in the western world. However, little is known about the ultrasound and mammography screen-detected T1 invasive non-palpable breast cancer (NPBC) in asymptomatic Chinese women. RESULTS: With the increase of tumor size (T1a, b, c), lymph node positivity (8.7%, 18.3%, 26.0%, p = 0.018), pN (p = 0.028) and TNM stage (p = 0.035) increased accordingly. Tumor size (T1a, b, c) was correlated with high Ki-67 index (defined as ≥ 14%, 37.9%, 45.8%, 56.2%, p = 0.017), chemotherapy (20.4%, 35.2%, 57.3%, p < 0.001) and targeted therapy (2.9%, 9.9%, 15.1%, p = 0.008). T1a disease had higher chance of being luminal A and accompanied with ductal carcinoma in situ (DCIS), while T1c tumor being triple-negative and without DCIS. The 5-year disease free survival (DFS) of T1a, b, c NPBC were 99.0%, 96.9% and 92.9%, whereas the 5-year overall survival (OS) were 100.0%, 100.0% and 97.9% respectively. There was no significant difference in 5-year DFS or OS among the T1 NPBC subgroups or subtypes/immunophenotypes. PATIENTS AND METHODS: From 2001 to 2014, 4,574 screening positive women received biopsies in Peking Union Medical College (PUMC) Hospital, and 729 NPBC including 437 T1 unilateral invasive NPBC were diagnosed. With a median follow-up time of 32 months (6-163 months), the clinicopathological characteristics, treatment choice, 5-year DFS and OS were compared between T1a, T1b and T1c NPBC. The DFS and OS prognostic factors were identified. CONCLUSION: Screen-detected T1 invasive NPBC could be regarded as low-risk cancer in Chinese women. TNM stage and LN metastasis instead of molecular subtype was identified as the DFS prognostic factors while radiotherapy as the OS predictor.

RESUMO

PURPOSE: Research on the mechanism of Bushen Jianpi decoction (BJD) for preventing and treating osteoporosis caused by aromatase inhibitors (AI) during treatment for breast cancer resection. METHODS: An ovariectomized mouse model was established using random division into 6 groups: a sham ovariectomized group, a blank control group, a control group, an alendronate group, a BJD group, and a drug combination group. Mice breast cancer cell lines (4T1) were cultured and seeded into the armpits of 6 groups of BALB/c mice. The mouse breast cancer postoperative model was built when resecting the tumor after 3 weeks following seeding tumor. After 1 weeks, the 6 groups of mice were given different drugs. Then the following analyses were made: estradiol (E2) levels and alkaline phosphatase (ALP) levels in the serum; detection of in vitro bone density and calcium and bone phosphorus content; tumor pathology and immunohistochemistry detection. RESULTS: The results suggested that BJD decreased levels of ALP in ovariectomized mice, and there was a trend for improved bone loss. BJD strengthened the trend of alendronate to improve bone loss, improved bone density, bone calcium and phosphorous, and reduced ALP. BJD had a certain role on the promotion of the expression of estrogen receptors (ERs) in the relapse of the tumor tissue. CONCLUSIONS: Combined therapy with BJD and alendronate can act synergistically against osteoporosis, which was possibly related to a reduced bone conversion rate through inhibiting bone resorption. BJD may block the MAPK signal pathway in breast cancer cells, increasing the expression of ERs and making cancer cells sensitive to endocrine treatment.

RESUMO

PURPOSE: The mainstay modality of breast cancer screening in China is the hospital-based opportunistic screening among asymptomatic self-referred women. There is little data about the ultrasound (US) detected non-palpable breast cancer (NPBC) in Chinese population. METHODS: We analyzed 699 consecutive NPBC from 1.8-2.3 million asymptomatic women from 2001 to 2014, including 572 US-detected NPBC from 3,786 US-positive women and 127 mammography (MG) detected NPBC from 788 MG-positive women. The clinicopathological features, disease-free survival (DFS) and overall survival (OS) were compared between the US- and MG-detected NPBC. Prognostic factors of NPBC were identified. RESULTS: Compared to MG, US could detect more invasive NPBC (83.6% vs 54.3%, p<0.001), lymph node positive NPBC (19.1% vs 10.2%, p=0.018), lower grade (24.8% vs 16.5%, p<0.001), multifocal (19.2% vs 6.3%, p<0.001), PR positive (71.4% vs 66.9%, p=0.041), Her2 negative (74.3% vs 54.3%, p<0.001), Ki67 high (defined as >14%, 46.3% vs 37.0%, p=0.031) cancers and more NPBC who received chemotherapy (40.7% vs 21.3%, p<0.001). There was no significant difference in 10-year DFS and OS between US-detected vs MG-detected NPBC, DCIS and invasive NPBC. For all NPBC and the US-detected NPBC, the common DFS-predictors included pT, pN, p53 and bilateral cancers. CONCLUSION: US could detect more invasive, node-positive, multifocal NPBC in hospital-based asymptomatic Chinese female, who could achieve comparable 10-year DFS and OS as MG-detected NPBC. US would not delay early detection of NPBC with improved cost-effectiveness, thus could serve as the feasible initial imaging modality in hospital-based opportunistic screening among Chinese women.

RESUMO

BACKGROUND: Trastuzumab-based therapy is a standard, targeted treatment for HER2-positive breast cancer in the adjuvant setting. However, patients do not benefit equally from it and the association between HER2 amplification level and patients' survival remains controversial. A systematic review and meta-analysis was conducted by incorporating all available evidence to evaluate the association between disease free survival (DFS) and HER2 amplification level. RESULTS: Three cohort studies involving 1360 HER2-positive breast cancer patients stratified by HER2 amplification magnitude were eligible for meta-analysis. The combined HRs for DFS were 1.05 (95% CI: 0.80-1.36, p = 0.74) and 0.97 (95% CI: 0.73-1.29, p = 0.83) for HER2 gene copy number (GCN) and HER2/CEP 17 ratio. No evidence of heterogeneity or public bias was found. METHODS: Databases including PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL), were searched for eligible literature. HER2 amplification level was evaluated by fluorescence in situ hybridization (FISH) in terms of gene copy number (GCN) and HER2/CEP17 ratio. Hazard ratios (HRs) for DFS with 95% confidence interval (CI) according to the amplification level of HER2 were extracted. The outcomes were synthesized based on a fixed-effects model. CONCLUSIONS: HER2 amplification level is not a prognostic factor for HER2-positive breast cancer with trastuzumab-based targeted therapy in the clinical adjuvant setting.

RESUMO

The aim of this study is to evaluate the efficacy of total saponins of Dioscorea (TSD), an extract of the Chinese herbal Bi Xie, on hyperuricemia and to elucidate the underlying mechanisms. The rat hyperuricemia model was established by administration of adenine. Thirty-two rats were randomly allocated into 4 groups: model group, low/high-dose TSD-treated groups, and allopurinol-treated group. Meanwhile, 8 rats were used as normal controls. Serum uric acid (UA), blood urea nitrogen (BUN), serum creatinine (Scr), and organic anion transporting polypeptide 1A1 (OATP1A1) levels were measured. Comparison between the model group and treatment (allopurinol and TSD) groups showed the serum UA levels were significantly decreased in treatment groups. TSD had similar effects to allopurinol. It was found that the OATP1A1 protein expression levels in treatment groups were higher than in model group and normal controls. And different from the allopurinol-treated groups, TSD-treated group had elevated OATP1A1 expression levels in the stomach, liver, small intestine and large intestine tissues. It was suggested that TSD may facilitate the excretion of UA and lower UA levels by up-regulating OATP1A1 expression.

RESUMO

Programmed cell death-1/programmed cell death-1 ligand 1 (PD-1/PD-L1) inhibitory signal pathway has been verified to be involved in the establishment of persistent viral infections. Blockade of PD-1/PD-L1 engagement to reinvigorate T cell activity is supposed to be a potential therapeutic scheme. Studies have verified the participation of PD-1/PD-L1 in hepatitis C virus (HCV) core protein-regulated immune response. To determine the roles of PD-1/PD-L1 signal pathway in HCV F protein-induced immunoreaction in chronic HCV infection, variations in T cells were examined. The results showed that PD-1 expression on CD8(+) and CD4(+) T cells was increased with HCV F stimulation in both chronic HCV patients and healthy controls, and could be reduced partly by PD-1/PD-L1 blocking. Additionally, by PD-1/PD-L1 blocking, HCV F-induced inhibition of T cell proliferation and promotion of cellular apoptosis were partly or even totally recovered. Furthermore, levels of both Th1 and Th2 cytokines were elevated in the presence of anti-PD-L1 antibody. All these results indicated that PD-1/PD-L1 signal pathway also participates in HCV F protein-induced immunoregulation. PD-1/PD-L1 blocking plays important roles in the restoration of effective functionality of the impaired T cells in chronic HCV patients.

RESUMO

Cytotoxic T lymphocyte associated antigen-4(CTLA-4) is an inhibitory receptor with great value in the progression of hepatitis C virus (HCV) infection related diseases. To determine the potential associations of IL-28B rs12979860 and CTLA-4 rs231775, rs3087243 and rs5742909 polymorphisms with the generation of HCV F protein, susceptibility and outcomes of HCV infection, a total of 375 healthy controls, 219 HCV spontaneous recovered patients and 600 chronic HCV patients from Southeast China were recruited and genotyped in this study. And the relative mRNA levels of CTLA-4 in T cells were detected. Logistic regression analysis showed that rs231775 A allele was associated with significantly higher rate of spontaneous viral clearance in anti-HCV F antibody negative patients (adjusted OR=0.512, P=0.008), but allele A was related to higher mRNA level of CTLA-4 with the generation of HCV F protein. And rs5742909 T allele added up to the risk of HCV infection chronicity significantly in patients with the presence of HCV F protein (adjusted OR=2.698, P=0.003). Also, the rs5742909 CC genotype, along with the presence of HCV F protein, indicated a significantly higher CTLA-4 level than that in anti-HCV F antibody negative patients. The AG+AA genotype of rs3087243 significantly increased the susceptibility to HCV infection in subjects over 56 years old (adjusted OR=1.595, P=0.011). Genotype-genotype interaction between IL-28B rs12979860 and CTLA-4 rs3087243 was found to be significantly associated with increased susceptibility to HCV infection (adjusted OR=1.509, P=0.005). Haplotype analysis in CTLA-4 also showed significant association with the generation of HCV F protein. All these results indicated the importance of IL-28B and CTLA-4 polymorphisms and their associations with HCV F protein in the risk and chronicity of HCV infection in Chinese Han population in Southeast China.

RESUMO

The use of ultrasound in the diagnosis of axillary lymph node metastases from breast cancer in a Chinese population was investigated. Data for 1,049 with breast cancer were retrospectively collected. All patients had undergone pre-operative axillary ultrasound and then axillary lymph node dissection. The sensitivity, specificity and accuracy of axillary ultrasound in this cohort were 69.4%, 81.8% and 77.0%, respectively. The overall false-negative rate of ultrasound images was 30.6% (123/402). False-negative ultrasound rates for pathologic N1, N2 and N3 patients were 46.2%, 21.8% and 9.3%, respectively. In patients with stage T1 disease and fewer than three metastatic lymph nodes, the false-negative ultrasound rate was 52.2% (47/90). Moreover, breast cancer patients with a false-negative axillary ultrasound were more likely to have a large tumor (p < 0.001) and high tumor grade (p = 0.009). However, there were no statistically significant differences between accuracy of axillary ultrasound and age of patients or experiences of ultrasound practitioners. In conclusion, the sensitivity, specificity and accuracy of ultrasound in the diagnosis of breast cancer metastasis to the axillary lymph nodes in Chinese patients were assessed. These data could help us to carefully use axillary ultrasound to diagnose and predict breast cancer axillary lymph node metastasis.

RESUMO

Hepatitis C virus (HCV) is a major cause of chronic liver disease and has led to cirrhosis or hepatocellular carcinoma in a majority of infected individuals. We have previously demonstrated that the HCV alternate reading frame protein (F protein) is related to Th1/Th2 bias in chronic hepatitis C (CHC) patients, and we aimed to explore the relative molecular mechanisms here. A total of 104 cases including CHC patients and healthy donors were enrolled. T-bet and GATA-3 expression levels were analyzed in peripheral blood mononuclear cells (PBMCs). The levels of signal transducer and activator of transcription-1/-6(STAT1/6) and phosphorylated STAT1/6(pSTAT1/6) in PBMCs were measured by Western blotting. Our results showed that the levels of T-bet in PBMCs, as well as the levels of gamma interferon (IFN-γ) in sera, were decreased in anti-F protein antibody seropositive patients compared with anti-F protein antibody seronegative patients, whereas the levels of GATA-3 did not show difference between the two groups. Moreover, the decreased pSTAT1 and increased pSTAT6 were observed in PBMCs by HCV core/F protein stimulation with constant STAT1/6 expression. Taken together, it suggested that T-bet may be involved in Th1/Th2 bias induced by HCV F protein, and the disruption of STAT phosphorylation may participate in this mediation.

RESUMO

BACKGROUND: The posterior and anterior circumflex humeral artery (PCHA and ACHA) are crucial for the blood supply of humeral head. We aimed to identify simple landmarks for guiding the quick access to PCHA and ACHA, which might help to protect the arteries during the surgical management of proximal humeral fractures. METHODS: Twenty fresh cadavers were dissected to measure the distances from the origins of PCHA and ACHA to the landmarks (the acromion, the coracoid, the infraglenoid tubercle, the midclavicular line) using Vernier calipers. RESULTS: The mean distances from the origin of PCHA to the infraglenoid tubercle, the coracoid, the acromion and the midclavicular line were 27.7 mm, 50.2 mm, 68.4 mm and 75.8 mm. The mean distances from the origin of ACHA to the above landmarks were 26.9 mm, 49.2 mm, 67.0 mm and 74.9 mm. CONCLUSION: Our study provided a practical method for the intraoperative identification as well as quick access of PCHA and ACHA based on a series of anatomical measurements.

RESUMO

AIM: To investigate the clinical characteristics and prognosis of patients with malignant eyelid tumors. METHODS: This was a retrospective, non-randomized, clinical reviews. Between January, 2002 and December, 2011, 75 cases with histologically confirmed malignant eyelid tumors were evaluated. Patients' charts were reviewed for clinical information, treatment procedure, and disease course. Survival analysis in terms of recurrence-free survival was performed using age, sex, location of tumor and histopathological type. The follow-up ranged from 1 to 78 months (mean=21 months). RESULTS: The 75 eyelid tumors included 35 basal cell carcinoma (BCC, 46.7%), 22 sebaceous gland carcinoma (SGC, 29.3%), 7 squamous cell carcinoma (SCC, 9.3%), 10 malignant melanoma (MM, 13.3%), and 1 Merkel cell carcinoma (MCC, 1.3%). Recurrence developed in 17 cases (22.7%). The recurrence rate of BCC (4/35, 11.4%) was significant lower than MM (6/10, 60.0%, P<0.001). The mean interval of recurrence was 21 months (range 3-62) for all eyelid tumors. Tumor located at canthus had higher recurrence rate (50%) compared with those located at eyelid (19%, P<0.05). Histological type was independent variable for recurrence by Cox regression analysis. CONCLUSION: It is important to achieve a negative tumor margin in canthus located malignant eyelid tumor. Clinicians should have a high level of suspicion for recurrence according to histological type when treating patients with eyelid tumor.

RESUMO

The tumor-associated calcium signal transducer 2 (TACSTD2) gene has been reported to be highly expressed in many types of human epithelial cancers, and is associated with tumor metastasis and poor prognosis. The aims of the present investigation were to analyze the TACSTD2 and Cyclin D1 expression at the mRNA and protein levels and to assess its prognostic significance in invasive ductal breast cancer (IDC). The expressions of TACSTD2 and Cyclin D1 in IDC tissues were consistently higher than those in the tumor-adjacent non-malignant tissues by a one-step real-time polymerase chain reaction and immunohistochemistry (P<0.001 and P=0.023, respectively). The statistical analysis of clinicopathologic characteristics and immunohistochemistry by the χ(2) test showed that the high expression of TACSTD2 in IDC was correlated to histological grade (P=0.023), P53 status (P=0.042), Cyclin D1 status (P<0.001), lymph node metastasis (P<0.001), distant metastasis (P=0.004) and TNM staging (P<0.001). Kaplan-Meier survival and Cox regression analyses were performed to evaluate the prognosis of IDC. These analyses also showed that a high TACSTD2 expression (P=0.003), a high Cyclin D1 expression (P=0.041), and lymph node metastasis (P=0.006) were independent prognosis factors. Collectively, our studies demonstrated that the high expression of TACSTD2 correlates with a poor prognosis in IDC.

RESUMO

The definition of sub-health was studied from the angle of tumor dormancy again. We believe it is necessary to further supplement the present definition, diagnosis criteria, and assessment means. The definition of sub-disease and the division of a disease into four development stages (health --> sub-health --> sub-disease --> disease) were also brought up. Furthermore, we believe that application of regulating sub-health as preventive and therapeutic strategies for tumor is an anti-cancer method with Chinese features, which enriches the modern theories of tumor prevention and therapy.
