Background and purpose: Triple-negative breast cancer (TNBC) presents a high risk breast cancer that lacks the benefit from hormone treatment, chemotherapy is the main strategy even though it exists in poor prognosis. Use of adjuvant radiation therapy, which significantly decreases breast cancer mortality, has not been well described among poor TNBC women. The aim of this study was to evaluate whether the combination of chemotherapy and radiotherapy could significantly increase survival outcomes in TNBC women after mastectomy. Patients and methods: A prospective randomized controlled multi-center study was performed between February 2001 and February 2006 and comprised 681 women with triple-negative stage I-II breast cancer received mastectomy, of them, 315 cases received systemic chemotherapy alone, 366 patients received radiation after the course of chemotherapy. Recurrence-free survival (RFS) and overall survival (OS) were estimated. Simultaneously local and systemic toxicity were observed. Results: After a median follow-up of 86.5 months, five-year RFS rates were 88.3% and 74.6% for adjuvant chemotherapy plus radiation and adjuvant chemotherapy alone, respectively, with significant difference between the two groups (HR 0.77 [95% CI 0.72, 0.98]; P = 0.02). Five-year OS significantly improved in adjuvant chemotherapy plus radiation group compared with chemotherapy alone (90.4% and 78.7%) (HR 0.79 [95% CI 0.74, 0.97]; P = 0.03). No severe toxicity was reported. Conclusions: Patients received standard adjuvant chemotherapy plus radiation therapy was more effective than chemotherapy alone in women with triple-negative early-stage breast cancer after mastectomy. © 2011 Elsevier Ireland Ltd.

This study was conducted to explore programmed cell death-ligand-1 (PD-L1) expression and fibroblast growth factor receptor 1 (FGFR1) amplification in stage IIIB/IV lung squamous cell carcinoma (SQC). Correlations between PD-L1 and FGFR1, and with clinicopathological characteristics, efficacy of platinum-based chemotherapy, and prognosis were analyzed.One hundred and twenty-eight consecutive stage III/IV SQC patients were enrolled in this study from 2009 to 2014. Seventy-eight patients received platinum-based chemotherapy. Immunohistochemistry was used to assess PD-L1 expression and fluorescence in situ hybridization was applied to detect FGFR1 amplification.PD-L1 expression was detected in 61.7% (79/128) of lung SQC patients. Smokers had significantly higher PD-L1 expression rates than non-smokers (66.1% vs. 44.0%, P =0.042, respectively). The objective response and disease control rates for platinum-based chemotherapy were not significantly different between PD-L1 negative and positive patients (43.3% vs. 36.2%, P =0.434; 80.0% vs. 78.7% P =0.840, respectively); however, overall survival in PD-L1-negative patients was significantly longer than in PD-L1-positive patients (41.5 vs. 19.3months, P =0.001). Twenty-five percent (32/128) of patients displayed FGFR1 amplification, with a lower rate in stage III patients compared to stage IV (17.1% vs. 36.5%, P =0.013, respectively). There was no significant difference in FGFR1 amplification levels between overall response, disease control or overall survival rates. No correlation was observed between PD-L1 expression and FGFR1 amplification ( P =0.916).PD-L1 expression may function as a prognostic factor in Chinese stage III/IV SQC patients. FGFR1 amplification is more prevalent in late stage SQC patients but does not predict chemotherapy response. There is no apparent correlation between PD-L1 expression and FGFR1 amplification.

An enzyme (Phospholipase C Type I from Clostridium perfringens) was exposed to 0-810 J cm-2 of energy using laser light at wavelengths 808, 532, 1064 and 1342 nm and two LED light sources at wavelengths 810 and 640 nm. Enzyme responses were evaluated by measuring ceramide concentration using high performance thin-layer chromatography (HPTLC) at 0.5, 1, 2, 3, 4, 6, 17, 24 h after irradiation. The duration of effect was evaluated from the experimental data. The results show that enzyme activity can be increased by using both laser and LED sources whose wavelength is located within a certain range. The effect depends on the energy and wavelength of the light. The increase in enzyme activity continued for about 4 h after irradiation. This study shows that the duration of irradiation should be included as one of the main laser parameters when reporting on the effects of laser irradiation on enzymes. We also find that laser sources and LED sources have the same effect on enzyme activity if the wavelength and absorbed energy are equal. © 2010 Tianjin Medical University.

Recent studies have suggested that chromosomal aberrations of the MYC gene locus indicate an unfavorable prognosis in diffuse large B-cell lymphoma (DLBCL). However, there have been few reports on MYC translocation in Chinese patients. One hundred and six cases of DLBCLs were analyzed using interphase fluorescent in situ hybridization. Immunophenotyping analysis (CD20, CD3, CD10, Bcl-6, Mum-1) was also performed. MYC translocation was identified in 13 (12.3%) out of 106 cases. All MYC + DLBCLs showed a non-germinal center B-cell type. MYC + DLBCLs showed significantly poorer overall survival (OS) and progression-free survival, with a median OS and progression-free survival time of 4.7 and 3.2months, respectively (p<0.001). Multivariate analysis using a Cox proportional hazard model confirmed that MYC + (for OS, Hazards ratio 5.254; 95% CI, 2.354-11.723, p<0.001) was the strongest independent predictor. DLBCL with MYC translocation is a subgroup of non-germinal center B-cell DLBCL with poor outcome. This may be a clinical characteristic that is specific to Chinese patients. Because only a few patients received rituximab, its usefulness could not be assessed. Future studies with larger numbers of patients are required. © 2011 John Wiley & Sons, Ltd.

Purpose: Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. Methods: PubMed, Google scholar and China National Knowledge Infrastructure databases were searched for eligible articles in English and Chinese that were published before April 2012. Results: 6 studies involving 1,246 patients with hepatocellular carcinoma and 1,953 controls were included. The association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma in the Chinese Han population was significant under GG vs AA (OR = 1.48, 95% CI = 1.13 to 1.94). Limiting the analysis to the studies with controls in the Hardy-Weinberg equilibrium, the results were persistent and robust. Conclusions: In the Chinese Han population, the XRCC1 Arg399Gln gene polymorphism is associated with an increased hepatocellular carcinoma risk.

Accurate preoperative staging of rectal carcinoma is essential for optimal treatment. This study was designed to evaluate the accuracy and learning curve of endorectal ultrasonography (ERUS) in the preoperative staging of rectal carcinoma. We retrospectively analyzed the records of patients with rectal carcinoma who underwent preoperative ERUS followed by curative surgery at the Shanxi Province Tumor Hospital between January, 2007 and March, 2010. The patients were divided into three groups, namely A, B and C, depending on whether the examination was performed between January and December, 2007, between January and December, 2008 or between January, 2009 and March, 2010, respectively. Five physicians with no prior experience in ERUS performed the examinations. We compared the ERUS staging with the pathological findings using the tumor-node-metastasis (TNM) classification. The accuracy of ERUS in T and N staging after each additional consecutive 20 patients was calculated for physicians D, E and F. A total of 319 patients underwent ERUS prior to surgery. There were 38 patients in group A, 135 in group B and 146 in group C. Two of the five physicians performed only 47 of the 319 examinations, whereas the remaining 272 patients were examined by physicians D (n=162), E (n=64) and F (n=46). The overall accuracy in assessing the extent of rectal wall invasion (T) was 67%, with 16% of the cases overstaged and 17% understaged and the accuracy in assessing nodal involvement (N) was 66%, with 11% of the cases overstaged and 23% understaged. The total T and N staging accuracy of physicians D, E and F was 75 and 72%; 59 and 59%; and 50 and 52%, respectively. For physicians D, E and F, the accuracy of T and N staging after each additional 20 patients was calculated and the curve of the accuracy reached a plateau after physician D completed 80 cases. Therefore, ERUS is a valuable tool for assessing the depth of tumor invasion and it appears that after ~80 cases a physician may be considered able to apply it efficiently.

We investigated the relationship between the urokinase type plasminogen activator receptor (uPAR) in sera and tissues of patients with cervical cancer and the clinical and pathological features of the cancer. Immunohistochemistry (SABC method) was used to detect uPAR expression in cervical cancer and normal tissues; ELISA was employed to assay the uPAR levels in cervical cancer and normal tissues and the corresponding sera. The immunohistochemistry results showed that there were 37 cases of uPAR expression in 56 patients of cervical cancer with a positive expression rate of 66%, whereas there was no uPAR expression in normal cervical tissues. The uPAR levels in cancer tissue from patients with cervical cancer (70.92 ± 28.55 ng/100 mg protein) were significantly higher than those of adjacent tissues obtained from the cancer patients (11.01 ± 5.40 ng/100 mg protein) (P < 0.001). Furthermore, the tissue uPAR levels are correlated with the TNM stages, lymph node metastasis, and the degree of differentiation instead of tumorinfiltrating and vessel thrombosis. Serum uPAR levels of patients (2.38 ± 0.29 ng/ml) were significantly increased compared with health control group (0.50 ± 0.16 ng/ml) (P < 0.001). Single-factor analysis shows that the serum uPAR levels of preoperative patients are related with clinical grade, lymph node metastasis, vein embolism, and the depth of infiltration instead of tumor differentiation. We conducted multiple regression analysis and found that the factors affecting preoperative serum suPAR include clinical stage (P = 0.000), pelvic lymph node metastasis (P = 0.000), and depth of myometrial invasion (P = 0.001). The serum suPAR levels of patients with cervical cancer after surgery are significantly decreased compared with preoperation (P < 0.001). The uPAR levels of serum and tissue present a positive correlation (r =0.705, P < 0.001). The soluble uPAR in serum (su-PAR) may be a more convenient indicator to reflect the uPAR system activity in vivo. It could be a tumor marker for clinical diagnosis, treatment, and prognosis monitor of cervical cancer. © 2012 Wiley Periodicals, Inc.

To evaluate the ultrasound (US) features of the encapsulated papillary thyroid carcinoma (EPTC). Based on ultrasonographic features including shape, size, border, echogenicity, hypoechoic halo and microcalcification, 33 cases of EPTC were classified into two groups: 21 cases in irregular shape group and 12 cases in spherical or oval shape group. EPTC in the irregular shape group showed some ultrasonographic features including jagged border, irregular tumor shape and marked hypoechogenicity, while the ultrasonographic features of EPTC in the spherical or oval shape group included smooth border, regular shape, isoechogenicity and hypoechoic halo. Hypoechoic halo and isoechogenicity were found more frequently in EPTC of spherical or oval shape group than those in EPTC of irregular shape group. The size of EPTC in the spherical or oval group was commonly larger than that of EPTC in the irregular shape group. The findings indicate that EPTC have some ultrasonographic features similar to benign follicular thyroid tumors.

To evaluate the application value of preoperative ultrasound-guided drawing for locating thyroid micronodule in surgery.A total of 88 patients (with 137 thyroid micronodules) who underwent thyroid surgery was included in the prospective study. Preoperative thyroid ultrasound was conducted in all patients. Select criteria: the maximum diameter of nodule 1 cm. All patients were randomly divided into two groups: 46 patients (68 micronoduls) in experimental group with ultrasound-guided drawing location of thyroid micronodule and 42 patients (69 micronoduls) in control group without ultrasound-guided drawing location of thyroid micronodule.All thyroid micronodules of experimental group were found quickly and accurately in surgery, and 4 micronodules in 4 patients of control group were not found in surgery. US examinations 3 months after surgery showed that all micronodules in experimental group were completely removed and 4 micronodules in control group retained.Ultrasound-guided drawing is a useful technique for locating and searching accurately thyroid micronodule in surgery.
