Objective: To retrospectively analyze related factors of subtype transformation and to identify prognostic factors for patients with retroperitoneal liposarcoma (RPLS). Methods: This study retrospectively analyzed the clinical data of 92 patients with RPLS, which were confirmed by postoperative pathology from July 1997 to October 2014 in Henan Provincial Tumor Hospital. Related studies were reviewed, and the prognoses were followed up. The factors may affect subtype transformation or prognoses were applied to the statistical analysis. Results: A total of 74 patients with RPLS were included according to the recruiting standard. The 5-year survival rate was 48.65% . Lobulated tumors (P=0.013) were the correlative factors that influenced subtype transformation. The Log- rank test showed that the age at diagnosis (P=0.045), multi-visceral resection (P=0.042), tumor necrosis (P<0.001), subtype transformation (P< 0.001), and malignant level of pathological subtypes of the first operation (P<0.001) influenced overall survival. Multivariate Cox regression analysis showed that tumor necrosis and the malignant level of the initial histological grade were independent factors of overall survival. Conclusion: Lobulated tumors are likely to transform the subtype. The prognosis of patients with RPLS is correlated with multi-visceral resection, tumors necrosis, subtype transformation, and the malignant level of pathological subtypes of the first operation. Multi-visceral resection could not improve the 5-year survival rate of RPLS, and adjuvant therapy could not improve the prognosis.

Introduction: This study aims to evaluate the differentiated effectiveness of MR diffusion tensor imaging (DTI) to postoperative recurrent glioma and radiation injury. Methods: Conventional MRI and DTI examination were performed using Siemens 3.0 T MR System for patients with new contrast-enhancing lesions at the site of treated tumor with postoperative radiotherapy. The region of interest was manually drawn on ADC and FA maps at contrast-enhancing lesion area, peri-lesion edema, and the contra-lateral normal white matter. Then ADC and FA values were measured and, the ADC ratio and FA ratio were calculated. Twenty patients with recurrent tumor and 15 with radiation injury were confirmed by histopathologic examination (23 patients) and clinical imaging follow-up (12 patients), respectively. The mean ADC ratio and FA ratio were compared between the two lesion types. Results: The mean ADC ratio at contrast-enhancing lesion area was significantly lower in patients with recurrent tumor (1.34∈±∈0.15) compared to that with radiation injury (1.62∈±∈0.17; P∈<∈0.01). The mean FA ratio at contrast-enhancing lesion area was significantly higher in patients with recurrent tumor (0.45∈±∈0.03) compared to that with radiation injury (0.32∈±∈0.03; P∈<∈0.01). Neither mean ADC ratio nor FA ratio in edema areas had statistical difference between the two groups. A recurrent tumor was suggested when either ADC ratio∈<1.65 or/and FA ratio >0.36 at contrast-enhancing lesion area according to the receiver operating characteristics curve analysis. Three patients with recurrent tumor and two with radiation injury were misclassified. Conclusion: DTI is a valuable method to distinguish postoperative recurrent glioma and radiation injury. © 2010 Springer-Verlag.

This study was purposed to explore the effect of hyperthermia on sensitivity of multiple myeloma cells RPMI 8226 to adriamycin (ADM) and its mechanism. The working concentration of ADM against RPMI 8226 cells was defined by MTT assay. RPMI 8226 cells were divided into 4 groups: control group, hyperthermia (42°C) group, chemotherapy (ADM) group and combination group (42°C + ADM), the survival rate of RPMI 8226 cells in 4 groups was detected by trypan blue exclusion, the inhibitory effect of hyperthermia on proliferation of RPMI 8226 cells was detected by MTT assay, the cell cycle distribution, apoptosis rate of cells, intracellular ADM concentration and P-gp expression level were measured by flow cytometry. The 1/4 IC(50) of ADM was defined as the working concentration in the experiment. The results indicated that the hyperthermia promoted the entering the cells from in G(0)/G(1) phase into S and G(2)/M phases, the expression of P-gp protein on cells in hyperthermia and combination groups was down-regulated, the intracellular ADM concentration in combination group obviously increased. It is concluded that the hyperthermia combined with ADM obviously enhance the inhibitory effect on proliferation of RPMI 8226 cells. The hyperthermia increases the sensitivity of RPMI 8226 cells to chemotherapy through down-regulating the expression of P-gp protein on cells and increasing the intracellular ADM concentration.

To explore the effects of splenic flexure and sigmoid colon variation on anastomosis after left colectomy. The clinical data of 76 descending colon patients were collected retrospectively from March 2004 to April 2011 at our hospital. Statistical analysis was performed for the types of splenic flexure and sigmoid colon with regards to the choice of anastomosis. There were mesenteric type (n = 55), mobile type (n = 7) and adhesive type (n = 14) for splenic flexure. And among 61 regular types, 15 were of variable type for sigmoid colon variation. There was significant difference of anastomosis between the types of sigmoid colon variation [43 (78.2%) vs 5 (71.4%) vs 9 (64.3%), P > 0.05] while no significant difference existed between the types of splenic flexure [I type 56(91.8%) vs II type 1 (14.3%), III or IV type 0, P < 0.05]. A clinician should pay more attention to the types of sigmoid colon variation. And it helps to select the right approach of anastomosis after left colectomy.

OBJECTIVE: To evaluate the role of magnetic resonance imaging (MRI) in the detection of residual disease for patients after excisional biopsy of breast carcinoma, before re-excision. MATERIALS AND METHODS: We performed a retrospective review of 97 patients who underwent MRI soon after excisional biopsy of breast carcinoma with undeterminable margin status before further surgical intervention to determine the value of MRI in detecting residual disease. RESULTS: The positive predictive value was 50.0%. The negative predictive value was 78.9%. The MRI detected 54.5% of the residual disease for invasive ductal carcinoma and 100% for ductal carcinoma in situ. Positive predictive value and sensitivity for MRI conducted within 14 days of the original surgery were lower than those for MRI conducted after 14 days of the original surgery, being 31.6% and 46.2% versus 66.7% and 73.4%, respectively. The difference between the positive predictive value within 14 days versus after 14 days was statistically significant. CONCLUSION: Magnetic resonance imaging in detecting residual disease soon after excisional biopsy for breast carcinoma had a low positive predictive value and moderately high negative predictive value. Magnetic resonance imaging was more sensitive in detecting residual ductal carcinoma in situ than invasive ductal carcinoma. Magnetic resonance imaging conducted more than 14 days after the original biopsy had a significantly higher positive predictive value than MRI done within 14 days. © 2012 Lippincott Williams & Wilkins, Inc.

Recent reports have shown that cancer stem cells exist in many malignancies. Side population (SP ) cells are used to enrich cancer stem-like cells in many cell lines and fresh tumor specimens. In this study, we cultured primary esophageal squamous cell carcinoma (ES CC) cells from ES CC tissue specimens. SP cells from primary ES CC cells were more resistant to chemotherapeutic reagents and formed more colonies in vitro than non-SP cells. In addition, xenograft experiments revealed that SP cells were more tumorigenic in vivo. Further results indicated that the PI3K/Akt pathway is essential to SP cells through the regulation of ABCG2 transporter function. Furthermore, PTEN, rather than mTOR, was found to be involved in SP cell regulation in primary ES CC cells. These findings reveal that SP cells are enriched for cancer stem-like cells in primary ES CC cells and that the PTEN/PI3K/Akt pathway regulates this stem-like population. This study indicates that SP cells in primary culture cells from tissue specimens could be a promising model for cancer stem cell research and may help researchers develop novel therapeutic strategies or efficient drugs that target ESCC stem-like cells. © 2011 Landes Bioscience.

To summarize the results of endoscopic screening of esophageal, gastric cardiac and gastric cancers in the high-risk population, and analyze the influencing factors such as age, gender and biopsy rate on their detection and early diagnosis rates. Nine high incidence cities and counties of esophageal cancer in Henan province were included in this study. People aged 40-69 years were set to the target population. Excluding contraindications for gastroscopy, in accordance with the national technical scheme of early cancer diagnosis and treatment, gastroscopic screening and biopsy pathology for human esophageal, cardiac and gastric cancers were carried out. During the 3-year period, a total of 40 156 subjects were screened. Among them, 18 459 cases of various precancerous lesions (46.0%) were detected. The cancer detection rate was 2.3% (916 cases), including 763 cases of early cancers. The diagnosis rate of early cancers was 83.3%. Precancerous lesions were detected in 9297 cases (23.2%) for esophagus and 9162 cases (22.8%) for gastric cardia as well as stomach, respectively. The results of this study demonstrate that endoscopic screening is feasible for early detection, diagnosis and treatment of esophageal, gastric cardia and gastric cancers among high risk population in high incidence area. Exploration analysis of relevant affecting factors may help to further improve the screening project for early diagnosis and treatment of those cancers.
