RESUMEN
Objective: To investigate the clinicopathological characteristics of breast squamous cell carcinoma and to analyze the relationship between its immune microenvironment tumor infiltrating lymphocytes (TILs) and prognosis. Methods: Forty-four cases of primary squamous cell carcinoma of the breast diagnosed and treated in the First Affiliated Hospital of Air Force Medical University, Xi'an, China from January 2006 to July 2022 were selected. Their clinicopathological characteristics were analyzed. The cell composition of TILs was evaluated using immunohistochemistry (Mainly markers of B lymphocytes, T lymphocytes and plasma cells). The relationship between TILs and prognosis was also analyzed. Results: The 44 patients of breast squamous cell carcinoma were all female and all were invasive carcinoma. Eight cases (8/44, 18.2%) were squamous cell carcinoma, while 36 cases (36/44, 81.8%) were mixed squamous cell carcinoma. The mixed components included non-specific carcinoma and spindle cell metaplastic carcinoma (17 cases each). One case contained ductal carcinoma in situ of the breast and 1 case contained tubular carcinoma. The proportion of squamous cell carcinoma was 10% to 90%. The cases with pure squamous cell carcinoma often had a large cystic cavity, which was lined by atypical squamous epithelium, while infiltrating squamous cell carcinoma nests were seen in the breast tissue around the cystic cavity. Immunohistochemical staining showed that p63 and CK5/6 were expressed in the squamous cell carcinoma component, but ER, PR and HER2 were not, except for one case of HER2 1+. The positive rates of TRPS1 and PDL-1 were 76% and less than 1%, respectively. Fifteen cases were in the high TILs group (TILs≥30%) and 29 cases were in the low TILs group (TILs<30%). Twenty-three patients were followed up for 5 to 118 months. Among them, 12 died within 3 years and 9 were alive at the end of the follow up. There was no significant difference in TNM stage, TILs and prognosis between simple squamous cell carcinoma and mixed squamous cell carcinoma. Conclusions: Breast squamous cell carcinoma can be divided into simple squamous cell carcinoma and mixed squamous cell carcinoma. There are differences in gross findings and histology between the simple and mixed squamous cell carcinoma of the breast. Sufficient samples should be taken to avoid missing the diagnosis of a minor squamous component. The prognosis of patients with high TILs is significantly better than that of patients with low TILs. The expression rate of TRPS1 in primary squamous cell carcinoma of breast is high and helpful to the differential diagnosis from metastatic squamous cell carcinoma.

Objective: To investigate the efficacy and safety of percutaneous closure of ventricular septal rupture (VSR) after acute myocardial infarction (AMI) and the risk factors of all-cause mortality at 30 days after operation. Methods: This is a retrospective case series study. A total of 69 patients with post-AMI VSR, underwent percutaneous closure of VSR from October 2013 to May 2020 in Department of Cardiology of Henan Provincial People's Hospital and Department of Cardiology of Central China Fuwai Hospital, were included. Patients were divided into survival group (53 cases) and non-survival group (16 cases) according to the status at 30 days after operation. Clinical data were collected and analyzed during hospitalization. Telephone follow-up was performed 30 days after operation. The primary safety endpoint was occlusion failure and all-cause mortality at 30 days post operation. The secondary safety endpoint was the operation related or non-operation related complications. Efficacy endpoint included NYHA classification of cardiac function, index measured by right heart catheterization and echocardiography. Multivariate logistic regression was performed to analyze the risk factors of all-cause mortality at 30 days after operation. Results: A total of 69 patients, aged 67 (64, 71) years, including 42 women (60.9%), were enrolled in this study. All-cause death occurred in 16 patients (23.2%), including 13 in-hospital death and 3 death during follow-up. There were 4 cases of closure failure (5.8%). Among the 65 patients with successful closure, 12 (18.5%) experienced operation-related complications, among which 8 (12.3%) experienced valve injury. The mortality was significantly higher in patients with operation-related complications than that in patients without operation-related complications (41.7% (5/12) vs. 13.2% (7/53), P = 0.022). One case received percutaneous closure of VSR and PCI, this patient experienced new-onset AMI immediately post procedure and died thereafter (1.5%). One case (1.5%) developed multiple organ failure and 2 cases (3.1%) developed gastrointestinal bleeding post operation. All of the 65 patients with successful occlusion completed postoperative echocardiography, 56 patients completed cardiac function assessment at discharge, and 53 patients who survived up to 30 days post discharge completed clinical follow up by telephone. The NYHA cardiac function at discharge and 30 days after operation were significantly improved as compared to that before operation (P<0.001), the ratio of NYHA â and â ¡ patients was significantly higher post operation at these two time points as compared to baseline level (76.8% (43/56) vs. 23.1% (15/65), P<0.001, 77.4% (41/53) vs. 23.1% (15/65), P<0.001). The pulmonary circulation/systemic circulation blood flow ratio (Qp/Qs), pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic diameter (LVDd) were decreased, aortic systolic pressure (ASP) and left ventricular ejection fraction (LVEF) were increased post operation (P<0.05). Multivariate logistic regression analysis showed that WBC>9.8×109/L (OR=20.94, 95%CI 1.21-362.93, P=0.037) and NT-ProBNP>6 000 ng/L (OR=869.11, 95%CI 2.93-258 058.34, P=0.020) were the independent risk factors of mortality at 30 days. Conclusions: Percutaneous closure in VSR after AMI is safe and effective. The increase of WBC and NT-ProBNP are the independent risk factors of all-cause mortality at 30 days after operation.

Esophageal cancer has a high incidence among malignancies in China, but a comprehensive picture of the status of its surgical management in China has hitherto not been available. A nationwide database has recently been established to address this issue. METHOD: A National Database was setup through a network platform, and data was collected from 70 high-volume centers (>100 esophagectomies/per year) across China. Data was entered between January 2009 and December 2014, and was analyzed in June 2015 after a minimal follow-up of 6 months for all patients. 8181 patients with complete data who received surgery for primary esophageal cancer on the Database were included in the analysis. RESULT: In this series, there were 6052 males and 2129 females, with a mean age of 60.5 years (range: 22-90 years). The pathology in 95.5% of patients was squamous cell carcinoma. The pathological stage distribution was 1.2% in stage 0, 2.5% in Ia, 11.5% in Ib, 14.8% in IIa, 36.1% in IIb, 19.3% in IIIa, 8.3% in IIIb, 6.2% in IIIc. 1800 patients (22.0%) with locally advanced disease received preoperative neoadjuvant therapy and 3592 patients (43.9%) underwent postoperative adjuvant chemotherapy and/or radiotherapy. The esophagectomies were performed through left thoracotomy approach in 5870 cases (72.6%), through right chest approach in 2215 cases (27.4%) including right thoracotomy (21.3%) and VATS (6.1%). The 30-day postoperative mortality rate was 0.6% (43 patients), and the overall postoperative complication rate was 11.6% (951 patients). The 1-, 3-, and 5-year overall survival rates were 82.6%, 61.6%, and 52.9%, respectively. CONCLUSION: This National Registry Database from high-volume centers provides a comprehensive picture of surgical management for esophageal cancer in China for the first time. Squamous cell carcinoma predominates, but there is heterogeneity with respect to the surgical approach and perioperative oncologic management. Overall, surgical mortality and morbidity rates are low, and good survival rates have been achieved due to improvement of surgical treatment technology in recent years.

Objective: To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China. Methods: A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014. Results: Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade â ¡ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively. Conclusions: The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

Objective: To investigate the clinicopathologic features and grading of adenoid cystic carcinoma (ACC) of the breast. Methods: Sixteen cases of ACC of the breast were analyzed and graded according to the previous report. Immunohistochemical (IHC) staining was used to detect the immunophenotype, Ki-67 proliferative index and expression of EZH2, and the association with tumor grade and outcome was analyzed. Results: Of the 16 cases, 11 were grade â , with the epithelial and myoepithelial cells being arranged into tubular and cribriform structure with no solid component; three were grade â ¡, which were composed of mixed tubular, cribriform and solid component (<30%); and two were grade â ¢, which showed mainly solid component (>90%) and the tumor cells showed basaloid features with scanty cytoplasm and hyperchromatic nuclei, and mitotic count was>5/10 HPF. Immunophenotypically, the epithelial cells expressed CK7, CK8/18 and CD117; the myoepithelial cells expressed p63 and CK5/6; while the basaloid cells were positive for CK5/6 and CD117.Tubular and cibriform ACC showed low Ki-67 and EZH2 expression, while the two cases of solid variant with basaloid features showed high level of Ki-67 and EZH2 expression. Follow-up data were available in 13 cases with a median follow-up period of 42 months. Lung metastasis occurred after 12 months in one grade â ¡ case and the patient died of disease after 34 months. Vertebral metastasis occurred after 12 months in one grade â ¢ case and axillary lymph node metastasis occurred in another grade â ¢ case. All other patients were free of disease at the end of the follow-up periods. Conclusions: ACC shows morphologic spectrum varying from low to high grade, the latter can may give rise to local and distant metastasis. ACC should not be regarded simply as low malignant potential, and should be graded for optimal treatment.

OBJECTIVE: To explore the expression of delta-like 1 homolog (DLK1) gene in non-small cell lung cancer (NSCLC) and its regulatory mechanism. METHODS: The expression levels of DLK1 protein in 204 NSCLC tissues were examined by immunohistochemical (IHC) staining, and the correlation between DLK1expression and clinicopathological features was analyzed. Bisulfate sequencing PCR (BSP) of DNA samples from the tumor tissues of 18 NSCLC patients was performed to evaluate the DNA methylation status of CpG island in the DLK1 promoter region, and also compared with the corresponding IHC staining of DLK1 protein in the same samples. RESULTS: Among the 102 squamous cell carcinoma (SCC) tissue specimens and their adjacent normal bronchial epithelia, DLK1 was up-regulated in 72 and 37 samples, respectively (P=0.001), and among 102 adenocarcinomas (ADC) tissues and their adjacent alveolar tissues, DLK1 was up-regulated in 77 and 7 samples, respectively (P<0.001). In addition, overexpression of DLK1 was significantly associated with histological type, clinical stage and tumor size of NSCLC (P<0.05 for all). The expression of DLK1protein was inversely correlated with its promoter methylation (P<0.05). CONCLUSION: DLK1 expression is up-regulated in NSCLCs, which may be due, at least in part, to the DNA hypomethylation in the promoter region of theDLK1 gene.

Primary pulmonary EWS/PNET(PPES) is extremely rare and is associated with a poor prognosis. Tumor angiogenesis plays an important role in tumor, so it has become a hot topic in molecular targeted therapy. Anlotinib is a new oral small molecular multi-targeted receptor tyrosine kinase (RTK) inhibitor. This report describes a 20 year-old man with PPES. After 4 neoadjuvant chemotherapy cycles (VACwith alternating IE) combined with anlotinib, the left total pneumonectomy was performed. Then maintenance anlotinib monotherapy was continued, no sign of recurrence to date as an outcome. To our knowledge, this is the first demonstration of anlotinib combined with neoadjuvant chemotherapy efficacy in PPES.
RESUMEN
Pleomorphic adenoma with foci of squamous and mucinous differentiation can potentially be misdiagnosed as low-grade mucoepidermoid carcinoma. The circumscribed borders of the tumor, gradual merging of mucoepidermoid foci into areas typical of pleomorphic adenoma, and presence of keratinization are features against the latter diagnosis.

OBJECTIVE: Lung cancer is the leading cause of cancer death in the world and microRNAs (miRNA) have been found to be involved in the initiation and development of cancer by acting as potential oncogenes or tumor suppressor genes. PATIENTS AND METHODS: In this study, we investigated the expression of miR-34b in non-small cell lung cancer (NSCLC) patients and discussed the molecular mechanism of miR-34b in the invasion and migration of A549 cells in vitro. RESULTS: Our results showed that miR-34b was significantly down-regulated in primary cancer tissues when compared with the normal lung tissues. The over-expression of miR-34b inhibited migration and invasion, and promoted apoptosis of A549 lung cancer cells. Furthermore, Luciferase reporter assay validated YY1-associated factor 2 (YAF2) as a direct target of miR-34b and YAF2 expression was significantly increased in clinical NSCLC tissue samples. In addition, the over-expression of miR-34b inhibited YAF2, p-Jak2, p-STAT3 and MMP2 protein expression and promoted caspase 3 protein expression in cancer cells. CONCLUSIONS: Our results suggest that miR-34b may inhibit migration and invasion of NSCLC cells by targeting YAF2. Thus, our findings provide new insight into the molecular mechanisms of lung cancer metastasis and miR-34b may serve as a potential target in the treatment of human lung cancer.

Papillary glioneuronal tumor (PGNT) is a recently identified low-grade mixed glial-neuronal neoplasm of juvenile and young adult patients. The WHO classification does not categorize this tumor as a separate entity, but rather considers it as a variant of ganglioglioma. We present a new case of this rare entity, representing the 3rd case of this lesion in Chinese patients and review the findings in 34 patients from different case reports found in the international literature. This report describes a histologically similar-appearing lesion arising in the left frontoparietal lobe of a 23-year-old man. Its salient morphological characteristics are the presence of pseudopapillary structures composed of blood vessels, often hyalinized, lined by uniform small astrocytes and a proliferation of neurocytic cells which eventually admixed with ganglioid and ganglion cells. Sporadic Rosenthal fibers, foci of calcification, areas of hemosiderin deposition were identified. The mean Ki67 labeling index remained below 1%. Signs of anaplasia, in particular mitotic figures, endothelial proliferation or necrosis were consistently lacking. It is important that every new case of PGNT is reported to allow its recognition and classification. We perceive PGNT as a clinically and morphologically well-delineated subgroup of extraventricular low malignant potential neoplasm, whose presentation may allow for consideration as an entity.

The majority of human lung cancers originate from the carcinogenesis of bronchial epithelial cells. To study the malignant progression of human bronchial epithelial cells, we established a SV40T-transformed human bronchial epithelial cell line, and observed some biological and genetic changes of the cell line at different passages. In a 2-year culture, this cell line was approaching malignancy without obvious senescence. Cells in a later passage proliferated faster and required less growth factors than those of an early passage. After continued passaging, these cells were resistant to the terminal squamous differentiation effects of serum, and many of the cells grew anchorage independently. However, no tumor formed after cells were injected into nude mice. Some genetic alterations were found accompanying those morphological changes, such as 3p- and activation of c-myc, c-erbB-2 and bcl2, suggesting that those genetic alterations may contribute to the carcinogenesis of human bronchial epithelial cells at an early stage. This cell line should be particularly useful for studying the progression of human lung cancers.

AIM: In this study we investigated the relationship of the X protein of HBV and nuclear factor-kappa B (NF-kappa B) and the expression of NF-kappa B in human hepatocellular carcinoma tissues. METHODS: Immunohistochemistry SP method was used to detect the expression of NF-kappa B and the X protein of HBV in human hepatocellular carcinoma tissues of 52 cases. Gene transfection mediated by lipofectamine was used to transfect the eukaryotic expression vector pCDNA3.1-HBX of HBV x gene into human hepatocellular carcinoma cell line HCC-9204 and NF-kappa B was detected. RESULTS: NF kappa B was widely expressed in human hepatocellular carcinoma tissues in a total of 52 cases and its expression was related to the X protein of HBV. NF-kappa B was localized both in the cytoplasm and the nuclei of hepatocellular carcinoma cells in 11 cases which were positive for the X protein of HBV while in 41 cases negative for the X protein of HBV, NF-kappa B was only localized in the cytoplasm of hepatocellular carcinoma cells but translocated to the nuclei of hepatocellular carcinoma cells after the eukaryotic expression vector pCDNA3.1-HBX was transfected into HCC-9204 cells. CONCLUSION: This study strongly suggests that the nuclear factor NF-kappa B is widely expressed in hepatocellular carcinoma tissues in different styles according to the expression of the X protein of HBV. NF-kappa B is abnormally activated in hepatocellular carcinoma, which is probably related to the X protein of HBV. The X protein of HBV can activate NF-kappa B to translocate into nuclei of hepatocellular carcinoma cells.

Forestomach papilloma and carcinoma, as well as liver lesion, were induced in mice by gavaging precursors of the new nitrosamine, MAMBNA (N-3-methylbutyl-N-1-methylacetonylnitrosamine) and NaNO2. The results were-similar to those in mice and rats fed on preformed MAMBNA compound. However, the induction of such tumors by in vivo formation of MAMBNA required longer time and much larger doses. Moreover, the lesions of epithelial hyperplasia in the urinary bladder, lymphoid tumor, intestinal carcinoma and interstitial-cell tumor of the testis also developed in some of the experimental animals. This may indicate that the intragastric synthesis of MAMBNA is less effective in the production of forestomach tumors in mice.

OBJECTIVE: To evaluate the myocardial protecting effect of Shenmai injection (SMI) against ischemia/reperfusion injury in thrombolytic therapy with urokinase (UK) for acute myocardial infarction patients by 99mTc-MIBI myocardial imaging (SPECT). METHODS: Five hundred and thirty-seven patients were randomly divided into two groups. The SMI group (n = 292) was treated with thrombolytic treatment plus SMI and the control group (n = 245) with thrombolytic treatment only. Single photon emission computerized tomography (SPECT) was carried out on the 7th day after thrombolysis to determine the ischemic myocardial area (IMA) and ejection fraction (EF) in both groups and compared. RESULTS: The reperfusion rate of infarction related area (IRA) in the two groups was not different significantly (72.26% vs 72.65%, P > 0.05). The IMA in patients of the SMI group, no matter with or without reperfused IRA (211 cases and 81 cases) respectively, was significantly lower than that in the control group (178 cases and 67 cases) respectively, P < 0.01 and P < 0.05 respectively. The EF value in the SMI group was significantly higher than that in the control group (P < 0.01). CONCLUSION: Using SMI in early stage of thrombolytic treatment in acute myocardial infarction could significantly reduce IMA and increase EF. SMI showed good protective effect against myocardial ischemia/reperfusion injury in thrombolytic treatment.

AIMS: To improve prediction efficiency by incorporating complete blood count (CBC) into the TNM system on 5 year disease-specific survival (DSS) for patients with nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: The CBC of 3237 patients undergoing radiotherapy was retrospectively evaluated. In total, 2820 patients treated with non-intensity-modulated radiotherapy (IMRT) were randomly divided into development (1895 patients) and validation cohorts (925 patients). The association of potential risk factors with 5 year DSS was tested by Cox proportional hazards analysis and a prognostic index was created by assigning weighted scores proportional to a regression coefficient to each factor. Each cohort was divided into low, intermediate and high prognostic index. The prognostic index was validated in the validation cohort and compared with the TNM system on prediction of 5 year DSS. Validation was repeated in another independent group of 417 patients treated with IMRT. RESULTS: Eight independent prognostic factors were identified: gender, age, T or N stages, anaemia or thrombocytosis during radiotherapy, continuous reduction in haemoglobin, high neutrophil-lymphocyte ratio before radiotherapy. Each was assigned a number of points. The area under curve (AUC) of the prognostic index was larger than that of Union Internationale Contre le Cancer/American Joint Cancer Committee TNM system 2009 (0.697 versus 0.619, P < 0.001). CONCLUSION: A CBC-based prognostic index was developed and had a higher prediction efficiency on 5 year DSS in NPC than the TNM system alone.

This paper have carried out clinical study on 65 cases of congestive heart failure (CHF). (1) The insufficiency of Heart-Qi was the main cause of invasion of CHF. Along with aggravation of CHF, the Heart Yin deficiency developed into the Heart Yang deficiency and accompanying symptoms multiplied gradually. (2) Except plasma aldosterone (pALD) (P greater than 0.05), the levels of plasma atrial natriuretic polypeptide (pANP) and plasma angiotensin II (pAII) in the Heart Yin deficiency group was increased obviously compared with healthy persons (P less than 0.05-0.001). In the Heart Yang deficiency group, the levels of pANP and pALD was increased markedly (P less than 0.05-0.005), the level of pAII was decreased obviously (P less than 0.05), as compared with the Heart Yin deficiency group. (3) There were positive correlations between pANP and pALD (P less than 0.005), negative correlations between pAII and pANP, pALD (P less than 0.001).

A follow-up study questionaires on the quality of life of 130 cases with carcinoma of the esophagus who survived over 10 years postoperatively in our hospital, was conducted from January 1993 to December 1994. Results showed that 82.3% of the patients were able to eat ordinary food, 85.4% of them could carry on regular work and do physical labor, 86.2% of them had high spirits with a sense of well-being. A total number of 88.5% of the patients were very satisfied with their quality of life and 76.9% of them felt excellant. The authors reckoned that both the occurrance of complications in digestive tract and the postoperative mental status play important roles in affecting the quality of life.

Precancerous lesion is one of most important steps in tumorigenesis. It has been shown that retinoids have reliable effects on controlling many kinds of animal tumor and malignant tumor cell lines in vitro, but there is no laboratory report on the biological effect of retinoids on the precancerous lesion of human lung cancer. In this study the methods including of cell serum-free culture, precancerous model of human bronchial epithelium reconstructed in rat trachea/xenotransplanted in nude mice, flowcytometry, immunohistochemistry, TUNEL and pathological observation have been used to study the biological effects of N-(4-hydroxylphenol) retinamide (4-HPR), one new kind of retinoids, on transformed human bronchial epithelial cells in vitro and premalignant human bronchial epithelium in vivo. The results showed that in the study in vitro, the proliferation of transformed human bronchial epithelial cells, the ratio of cells in S phase, and the percentage of cells that positively react to antibody Ki-67 and mpm-2 were inhibited, but apoptotic cells were induced significantly by 4-HPR exposure. At the experiment in vivo, both growth rates and precancerous grades of the reconstructed human bronchial epithelium were reduced, and apoptotic cells were also observed in epithelium after 4-HPR treatment. The results suggested that 4-HPR is one of hopeful chemopreventive medicines to lung cancer.

In four SV40-immortalized human bronchial epithelia] cell lines established in our laboratory, we identified the SV40 integration sites by fluorescence in situ hybridization. We found that in the late passage of all the four cell lines, SV40 integrated at 12q23. It is possible that only SV40 integration at 12q23 is necessary for the immortalization of human bronchial epithelial cells. Some DNA sequences or genes in the region, such as IGF-1, may be involved with a proliferative advantage of the cells with 12q23 SV40 integration.
