    Approximately three percent of cancer patients suffer from significant side effects in normal tissue exposed to ionising radiation during radiotherapy (RT). Although RT is an effective therapy for cancer treatment, the treatment dose intensity is generally restricted to minimize the incidence of these severe reactions. This imposes tumour control limitations on most patients. A major goal of radiation biology research is to develop efficient predictive assays that could identify these hyper-radiosensitive (hRS) individuals prior to treatment. This predictive ability would enable the individualisation of RT doses, which should result in improvement of tumour control rates and a reduction in the incidence of RT side effects. Recent studies have reported a correlation between cellular and organismal RS and shortened telomeres. Interestingly, a number of DNA repair proteins have been found to be associated with telomeres. Additionally, individuals with cancer-proneness and RS syndromes, such as ataxia telangiectasia and Fanconi anemia, have shortened telomeres. In animal models, mutations in DNA repair genes such as Ku, has resulted in shortened telomeres. We have a unique bank of blood samples and lymphoblastoid cell lines (LCLs) from over 50 hRS patients. We have used traditional methods of telomere length assessment and a clinically relevant method, flow cytometry fluorescence in situ hybridisation (flow-FISH) to determine the telomere length in both LCLs and peripheral blood mononuclear cells from the hRS patients. Results from the screening of these samples will be presented. If clinical hRS can be correlated with shortened telomeres in some patients, flow-FISH may have utility as part of a pre-treatment hRS assay for use in the clinic

    Laser correlation spectroscopy was used to investigate plasma homeostasis in 82 patients with rectal cancer. The spectra of the blood plasma from 21 donors of the transfusion station were used as the control. The blood plasma homeostasis changes reheated with laser correlation spectrometry in the patients with rectal cancer allow to use them for diagnosis of this pathology

    Gallbladder cancer (GBC) is a highly fatal disease with poor prognosis and 5-year survival nutritional deterioration are associated with adverse outcomes in terms of cancer prognosis. Protein-calorie malnutrition is the single most common secondary diagnosis in a patient with cancer, and is a direct consequence of the anorexia of malignancy and altered host metabolism induced by the tumor. The present study of nutritional assessment is of particular interest for it helps in better understanding the extent of malnutrition in patients of GBC. A case-control study was designed comprising of 153 cases of GBC and 153 controls of gallstone disease (GSD). To assess the nutritional status of the GBC patients, anthropometric measurements such as height, weight, mid arm circumference, and skinfold thickness were recorded together with the biochemical parameters and their nutrient intake. The present study showed that GBC influences the nutritional status of the patients. Forty-three percent of GBC patients were malnourished with low body mass index (BMI). A significant reduction in all the anthropometric measures was observed for GBC patients compared to those with GSD. GBC patients had significantly low hemoglobin and serum albumin levels compared to the control group. The hemoglobin levels in case and control groups were 10.87 g/dl (+/-1.81 SD) and 11.62 g/dl (+/-1.89 SD), respectively (P anorexia and weight loss. Copyright 2006 Wiley-Liss, Inc.

    Objective To detect serum HER-2 oncoprotein levels in patients with operable and metastatic breast cancers, and to study the correlations between serum HER-2 level and lymph node status as well as other clinical parameters.Methods A total of 120 women were studied consisting of 10 healthy volunteers, 31 benign breast disease, 53 operable breast cancer, and 26 metastatic breast cancer patients. The levels of serum HER-2 were measured using an enzyme-liked immunosorbent assay (ELISA).Results The mean serum HER-2 levels were 9.6 + 1.5 ng/mL in healthy volunteers, 11.9 + 1.6 ng/mL in benign breast disease, 13.2 + 4.2 ng/mL in operable breast cancer, and 30.5 + 30.8 ng/mL in metastatic breast cancer patients. The former is much lower than the latter three (P=0.02, 0.001, 0.03, respectively). If using 15 ng/mL as a normal baseline, elevated serum HER-2 levels were observed in none of the healthy volunteers as well as patients with benign disease, but in 18.9% (10/53)operable breast cancer patients and 61.5% (16/26) metastatic patients. In patients with operable breast cancer, there was a positive correlation between serum concentrations of HER-2 and the size of primary rumor (P < 0.05), whereas there was no correlation between serum concentration and axillary lymph node or estrogen receptor status. In patients with metastatic disease, there was no correlation with site of metastases (P > 0.05).Conclusion Serum HER-2 level was strongly correlated with rumor loads and clinical stages, thus acting as a promising predictor of cancer recurrence in breast cancer patients.

    Cancer is a worldwide disease, and the psychosocial concerns are nearly universal among patients with cancer. The purpose of this study is to investigate the psychosocial correlates of life satisfaction among patients diagnosed with cancer in Jordan. A cross-sectional survey using 92 patients diagnosed with cancer used to collect data in regard to life satisfaction, depressive symptoms, psychological distress, coping, and perceived social support. In general, about 50% of patients reported high level of life satisfaction and 50% of the patients reported moderate levels of ability to effectively cope with life situations. Moreover, 78% of patients reported that they had depressive symptoms and 45.3% of them reported that they had moderate to severe depressive symptoms. Depressive symptoms had significant and negative correlation with life satisfaction (r = -0.50, p satisfaction (r = 0.05, p > 0.05). On the other hand, social support from others has positive and significant correlation with life satisfaction (r = 0.32, p satisfaction. Health professionals need to integrate their medical care with psychosocial intervention early at admission and during follow-up care, so early detection of psychological disturbances will help to implement effective treatment plans.

    Matrix metalloproteinase-9 (MMP-9) and heparanase (HPSE) are thought to be involved in tumor progression and metastasis. However, up to now, there are no studies that simultaneously investigated the expression levels of MMP-9 and HPSE in tumor tissue and serum of breast cancer patients. Their correlation in breast cancer pathological processes is unknown. The purpose of this study was to investigate the expression profile of MMP-9 and HPSE in breast cancer and to assess their clinicopathological significance. We measured serum MMP-9 and HPSE by enzyme-linked immunosorbent assay in healthy women, and in patients with benign and malignant breast disease. We also evaluated the expression of MMP-9 and HPSE protein in paraffin-embedded tumor tissues by immunohistochemistry. We then correlated serum and tissue levels of MMP-9 and HPSE in breast cancer samples and their expression with patients' clinicopathologic characteristics. We found that serum levels of MMP-9 and HPSE were significantly higher in breast cancer patients than in benign breast disease and in healthy controls (P = 0.001). There was positive correlation between MMP-9 and HPSE in breast cancer patients. The tissue and serum levels of MMP-9 were associated with histology grade, lymph node status, pathological stage, and lymphovascular invasion (all P < 0.05). The tissue levels of MMP-9 were also associated with ER (P = 0.038) and Ki-67 (P = 0.032). The tissue and serum levels of HPSE expression were associated with tumor size, histology grade, lymph node status, and pathological stage (all P < 0.05). Our findings suggested that MMP-9 and HPSE might further be evaluated as biomarkers for predicting progression and prognosis of breast cancer.

    Objective: To observe the incidence of anxiety in radiotherapy cancer patients in relation to their age, gender, education, marital status, performance status and type of disease. Design: Data regarding socio-demographic variables and disease type was recorded on a data capture form. The presence of anxiety was measured by administering taylor Manifest Anxiety Scale, Whereas patients, performance status was measured by administering Kernosky Performance Status Scale. Setting: Patients coming to the Department of Radiation Oncology, Shaukat Khanum Memorial Cancer Hospital and research center for their treatment were included in this study. Subjects and methods: A consecutive sample of 113 patients was taken and followed up to study the incidence of anxiety. Data over various parameters like age, gender, education, marital status, disease type and performance status was recorded. Results: Fifty percent of cancer patients receiving radiotherapy were found to be suffering from anxiety. Among 89% of patients, anxiety lowered after the therapy, in 3% it increased and remained static in 8% Patients with low education and low performance status presented with high anxiety. Among all the patients, no significant relationship between anxiety and gender, age, marital status and site of the disease was observed. Conclusion: Correlates other than radiotherapy procedure can also cause anxiety in patients by further research is required to establish those correlates of anxiety. It is recommended that all radiotherapy patients should be provided education and procedural information designed to familiarize them with the forthcoming experience in order to reduce their anxiety.

    Background: Cancer patients commonly suffer from weight loss since rapid tumor growth can cause catabolic metabolism and depletion of energy stores such as abdominal fat. In locally advanced pancreatic cancer this is even more pronounced due to abdominal pain, fatigue, nausea or malnutrition. In the present article, we quantify this frequently observed weight loss and assess its impact on outcome and survival. Methods: Data on demographics, biometrics, toxicity and survival were collected for the last 100 patients treated with neoadjuvant chemoradiation for locally advanced pancreatic cancer at our department (45.0 Gy and boost up to 54.0 Gy plus concurrent and subsequent gemcitabine), and the subcutaneous fat area at the umbilicus level was measured by computer tomography before and after chemoradiation. Results: After chemoradiation, patients showed a highly statistically significant weight loss and reduction of the subcutaneous fat area. We could determine a very strong correlation of subcutaneous fat area to patient BMI. By categorizing patients according to their BMI based on the WHO classification as slender, normal, overweight and obese, we found improved but not statistically significant survival among obese patients. Accordingly, patients who showed less weight loss tended to survive longer. Conclusions: In this study, patients with pancreatic cancer lost weight during chemoradiation and their subcutaneous fat diminished. Changes in subcutaneous fat area were highly correlated with patients' BMI. Moreover, obese patients and patients who lost less weight had an improved outcome after treatment. Although the extent of weight loss was not significantly correlated with survival, the observed trend warrants greater attention to nutritional status in the future. (orig.)

    Purpose: To compare pretreatment and midtreatment tumor intensity as measured by T2 fat-saturation (T2-FS) MRI and its association with treatment response in cervical cancer patients. Methods and Materials: Weekly MRI scans were performed for brachytherapy planning on 23 consecutive patients with clinical Stage IB1 to IIIB cervical cancer treated with definitive chemoradiotherapy. These scans were performed on a 1.5-T clinical scanner using a specialized pelvic coil. Mean signal intensity from T2-FS imaging was calculated for each tumor voxel. Average tumor intensity and tumor volume were recorded pre- and midtreatment (at Weeks 0 and 4). All patients subsequently underwent routine follow-up, including periodic clinical examinations and fluorodeoxyglucose–positron emission tomography imaging. Results: Mean follow-up for surviving patients was 14.5 months. Mean tumor volume at presentation was 49.6 cc, and mean midtreatment tumor volume was 16.0 cc. There was no correlation between initial tumor volume and pretreatment signal intensity (r = 0.44), nor was there a correlation between pre- or midtreatment tumor volume with disease-free survival (p = 0.18, p = 0.08 respectively.) However, having at least a 30% drop in signal intensity from pretreatment to midtreatment was correlated with having disease resolution on posttreatment fluorodeoxyglucose–positron emission tomography imaging (p = 0.05) and with disease-free survival (p = 0.03.) Estimated disease-free survival at 22 months was 100% for patients with at least a 30% drop in tumor signal intensity compared with 33% for patients above this selected threshold (p = 0.004). Conclusions: Longitudinal changes in T2-FS tumor intensity during chemoradiation correlated with disease-free survival in cervical cancer patients. Persistently high midtreatment tumor intensities correlated with a high risk of treatment failure, whereas large decreases in tumor intensity correlated with a favorable outcome.

    The cancer stroma, including cancer-associated fibroblasts (CAFs), is known to contribute to cancer cell progression and metastasis, suggesting that functional proteins expressed specifically in CAFs might be candidate molecular targets for cancer treatment. The purpose of the present study was to explore the possibility of using TEM1 (tumor endothelial marker 1), which is known to be expressed in several types of mesenchymal cells, as a molecular target by examining the impact of TEM1 expression on clinicopathological factors in gastric cancer patients. A total of 945 consecutive patients with gastric cancer who underwent surgery at the National Cancer Center Hospital East between January 2003 and July 2007 were examined using a tissue microarray approach. TEM1 expression in CAFs or vessel-associated cells was determined using immunohistochemical staining. Three items (CAF-TEM1-positivity, CAF-TEM1-intensity, and vessel-TEM1-intensity) were then examined to determine the correlations between the TEM1 expression status and the recurrence-free survival (RFS), overall survival (OS), cancer-related survival (COS), and other clinicopathological factors. Significant correlations between CAF-TEM1-positivity or CAF-TEM1-intensity and RFS, OS, or COS were observed (P < 0.001, Kaplan–Meier curves); however, no significant correlation between vessel-TEM1-intensity and RFS, OS, or COS was observed. A univariate analysis showed that CAF-TEM1-positivity and CAF-TEM1-intensity were each correlated with a scirrhous subtype, tumor depth, nodal status, distant metastasis, serosal invasion, lymphatic or venous vessel infiltrations, and pTMN stage. This study suggests that the inhibition of TEM1 expression specifically in the CAFs of gastric carcinoma might represent a new strategy for the treatment of gastric cancer

    Proton induced X-ray emission (PIXE) technique is used for analysis of trace elements present in the blood sera of ovarian cancer patients and healthy controls. This work is also intended to establish the role played by trace elements in carcinogenic process. It is observed that the concentrations of elements Ti, V, Cr, Mn, Fe, Ni, Rb and Sr are lower and the concentration of Cu is higher in the cancer patients when compared to controls. However, no change in concentration is found in the elements Co, Zn, As, Se and Br. Correlation analysis of the data using SPSS 16.0 has revealed a strong positive correlation between Ti-V, Ni-Co, Cu-Fe, As-Ti, Br-Ti, Br-V and Sr-Fe while strong negative correlations are observed for Cu-Ti, As-Cu and Br-Cu. Changes in trace elemental content are probably associated with ovarian carcinogenesis. (author)

    Breast cancer is the most common cancer among females. Approximately 30% of cancer patients develop depression or depressive adaptation disorder within 5 years post diagnosis. Low grade inflammation and subsequent changes in neurotransmitter levels could be the pathophysiological link. In the current study we investigated the association of neurotransmitter precursor amino acids with a diagnosis of depression or state anxiety in 154 subjects suffering from breast cancer (BCA(+)), depression (DPR(+)), both or neither. Sociodemographic parameters, severity of depressive symptoms, and state anxiety (ANX) were recorded. Neopterin, kynurenine/tryptophan and phenylalanine/tyrosine were analysed by HPLC or ELISA. Significantly higher serum neopterin values were found in DPR(+) patients (p = 0.034) and in ANX(+) subjects (p = 0.008), as a marker of Th1-related inflammation. The phenylalanine/tyrosine ratio (index of the catecholamine pathway) was associated with the factors "breast cancer" and "depression" and their interaction (all p depressive symptoms (r = 0.376, p precursor amino acids correlate with mental health, an effect which was much more pronounced in BCA(+) patients than in BCA(-) subjects. Aside from identifying underlying pathophysiological mechanisms, these results could be the basis for future treatment studies: in BCA(+) patients with depression the use of serotonin-noradrenaline reuptake inhibitors might be recommended while in those with predominant anxiety selective serotonin reuptake inhibitors might be the treatment of choice.

    Full Text Available Background and objective The patients with non-small cell lung cancer (NSCLC might contract anemia, however, whether anemia is one of the independent prognostic factors to the patients with NSCLC is still controversial. So the aim of this study is to investigate the correlation between anemia and overall survival (OS in patients with NSCLC. Methods 1 018 patients with operable NSCLC were retrospectively analyzed in our hospital from January 2000 to December 2008. Results The occurrence of anemia before operation was 252/1 018 (24.1%. The OS in NSCLC patients without anemia was (2 425.98±50.03 days, and the OS in patients with anemia was (2 107.15±93.86 days. There was significant difference in the OS between them (P=0.001. The patients with anemia in stage I had shorter survival time than those without anemia (P < 0.001. But there was no difference in other stage patients. TNM stage, gender, tumor size and lymph nodes metastasis were correlated with OS using Cox regression analysis. Conclusion Anemia is correlated with survival in operable NSCLC patients. Moreover, it is an independent prognostic factor in NSCLC patients with stage I.

    Purpose: We examined whether fluorine-18 fluorodeoxyglucose (FDG) uptake is related to the mammalian target of rapamycin (mTOR) signal pathway and its related proteins in pancreatic cancer patients. Methods: We retrospectively studied 53 pancreatic cancer patients who underwent FDG positron emission tomography (PET) or FDG PET/CT, and complete curative surgical resection. The SUV max, the tumor to nontumor activity of pancreas [T/N (P)] ratio and the T/N of liver [T/N (L)] ratio were calculated. The expressions of glucose transporter-1(Glut-1) and mTOR pathway proteins in pancreas cell lines were examined by immune blots. Excised tumor tissue was analyzed by immunohistochemistry using monoclonal antibodies for Glut-1, epidermal growth factor receptor (EGFR), mTOR, p70S6kinase (p70S6) and S6 ribosomal protein (S6). Results: The expressions of Glut-1, EGFR and p70S6 were significantly correlated with the SUV max, T/N (P) ratio and T/N (L) ratio. The expressions of mTOR and S6 were not correlated with all parameters. The expression of Glut-1 was positively correlated with the expressions of EGFR and p70S6, but not with mTOR or S6. S6 was positively correlated with p70S6. Conclusions: Glut-1, EGFR and p70S6 expressions are associated with the FDG uptake mechanism of pancreatic cancer. FDG uptake may predict the levels of EGFR and p70S6 expressions, and FDG uptake reflects glucose metabolism and cancer progression.

    Full Text Available Abstract Background Breast cancer (BC represents one of the leading causes of cancer related deaths worldwide. New tools for diagnostic staging and therapeutic monitoring are needed to improve individualized therapies and improve clinical outcome. The analyses of circulating tumour cells may provide important prognostic information in the clinical setting. Materials and methods Circulating tumour cells (CTC of 63 BC patients were isolated from peripheral blood (PB through immunomagnetic separation. Subsequently, RT-PCR or mPCR for the genes ga733.2, muc-1, c-erbB2, mgb-1, spdef and c-erbB2 were performed. Subsequently, expression data were correlated with the tumour stages. Fourteen healthy individuals served as controls. Results Significant correlations with tumour stages were found in single gene analyses of ga733.2, muc-1 and in multi-gene analyses of ga733.2/muc-1/mgb1/spdef. Furthermore, a significant correlation of Ca 15-3 and all studied genes was also observed. Conclusion Herein, we demonstrated a positive correlation of a gene signature consisting of ga733.2, muc-1, mgb1 and spdef and advanced stages of BC. Moreover, all studied genes and gene patterns revealed a significant correlation with Ca 15-3 positive cases.

    S100A9 was originally discovered as a factor secreted by inflammatory cells. Recently, S100A9 was found to be associated with several human malignancies. The purpose of this study is to investigate S100A9 expression in gastric cancer and explore its role in cancer progression. S100A9 expression in gastric tissue samples from 177 gastric cancer patients was assessed by immunohistochemistry. The expression of its dimerization partner S100A8 and the S100A8/A9 heterodimer were also assessed by the same method. The effect of exogenous S100A9 on motility of gastric cancer cells AGS and BGC-823 was then investigated. S100A9 was specifically expressed by inflammatory cells such as macrophages and neutrophils in human gastric cancer and gastritis tissues. Statistical analysis showed that a high S100A9 cell count (> = 200) per 200x magnification microscopic field in cancer tissues was predictive of early stage gastric cancer. High S100A9-positive cell count was negatively correlated with lymph node metastasis (P = 0.009) and tumor invasion (P = 0.011). S100A9 was identified as an independent prognostic predictor of overall survival of patients with gastric cancer (P = 0.04). Patients with high S100A9 cell count were with favorable prognosis (P = 0.021). Further investigation found that S100A8 distribution in human gastric cancer tissues was similar to S100A9. However, the number of S100A8-positive cells did not positively correlate with patient survival. The inflammatory cells infiltrating cancer were S100A8/A9 negative, while those in gastritis were positive. Furthermore, exogenous S100A9 protein inhibited migration and invasion of gastric cancer cells. Our results suggested S100A9-positive inflammatory cells in gastric cancer tissues are associated with early stage of gastric cancer and good prognosis

However, a few studies focus on the role of ET-1 in breakthrough pain (BP. The aim of this pivotal study was to explore the correlation between the plasma (ET-1 level and BP intensity. A total of 40 patients were enrolled in the study, and they were divided into two groups: BP group and non-BP group. Moreover, 20 healthy adults were used as the normal control group. Pain intensity was measured using visual analog scale (VAS scores of 1–10. Plasma ET-1 levels were detected by an ET radioimmunoassay kit. Subsequently, the correlation of ET-1 level with the VAS score and cancer types was analyzed by Pearson’s correlation coefficient. The plasma ET-1 level in the BP group (35.31±8.02 pg/mL was higher than that in the non-BP group (29.51±6.78 pg/mL and the normal control group (24.77±10.10 pg/mL, P<0.05. In addition, the VAS score in the BP group (7.45±0.82 was higher than that in the non-BP group (2.80±1.23, P<0.05. The plasma ET-1 level was positively correlated with the VAS score of the BP group (Pearson’s r=0.42. There was no significant correlation between the plasma ET-1 level and VAS score of the non-BP group (Pearson’s r=–0.22 or/and cancer types (P>0.05. The elevated plasma ET-1 levels were positively related to BP, and targeting ET-1 may provide a novel pain-reducing therapeutic treatment in BP.

    Full Text Available Vitamin D3 shows tumoristatic and anticancer effects by acting through the vitamin D receptor (VDR, while hydroxylation of 25-hydroxyvitamin D3 at position 1α by CYP27B1 is an essential step in its activation. The expression of both the VDR and CYP27B1 has been found in many normal and cancer tissues, but there is a lack of information about its expression in human bladder cancers. The aim of the present research was to examine whether the expression of the VDR and CYP27B1 in bladder cancer was related to the prognostic markers and disease outcome. We analyzed VDR and CYP27B1 in samples of tumor and normal tissues obtained from 71 urinary bladder cancer patients. The highest VDR immunostaining was found in normal epithelium and was significantly lower in bladder cancer cells (p < 0.001 with Mann–Whitney U test. VDR expression was lowest in more advanced (pT2b–pT4 (p = 0.005 with Mann–Whitney U test and metastasizing cancers (p < 0.05 and p = 0.004 with Mann–Whitney U test for nuclear and cytoplasmic VDR immunostaining, respectively. The lack of cytoplasmic and nuclear VDR was also related to shorter overall survival (for cytoplasmic VDR immunolocalization 13.3 vs. 55.3 months of survival, HR = 1.92, p = 0.04 and for nuclear VDR immunostaining 13.5 vs. 55.3 months of survival, HR = 2.47, p = 0.002 with Mantel-Cox test. In cases with the lack of high cytoplasmic VDR staining the non-classic differentiations (NDs was observed in higher percentage of tumor area. CYP27B1 expression was lower in cancer cells than in normal epithelial cells (p = 0.03 with Mann–Whitney U test, but its expression did not correlate with tumor stage (pT, metastasizing, grade, mitotic activity or overall survival. In conclusion, expression of the VDR and CYP27B1 are deregulated in urothelial bladder cancers. Although our results showing a relationship between the decreased VDR expression and prognostic markers and survival time indicate potential usefulness of

    Full Text Available While gastric cancer is a well established angiogenesis driven tumor, no data has been published regarding angiogenesis stimulated by mast cells (MCs positive for tryptase in bone metastases from gastric cancer patients (BMGCP. It is well established that MCs play a role in immune responses and more recently it was demonstrated that MCs have been involved in tumor angiogenesis. We analyzed infiltrating MCs and neovascularization in BMGCP diagnosed by histology. A series of 15 stage T3-4N2-3M1 (by AJCC for Gastric Cancer Staging 7th Edition BMGCP from bone biopsies were selected. Tumour tissue samples were evaluated by mean of immunohistochemistry and image analysis methods in terms of MCs density positive to tryptase (MCDPT, MCs area positive to tryptase (MCAPT, microvascular density (MVD and endothelial area (EA. A significant correlation between MCDPT, MCAPT, MVD and EA groups to each other was found by Pearson and t-test analysis (r ranged from 0.68 to 0.82; p-value ranged from 0.00 to 0.02. Our very preliminary data suggest that infiltrating MCs positive for tryptase may play a role in BMGCP angiogenesis, and could be further evaluated as a novel target of anti-angiogenic therapy.

    Full Text Available Abstract Background Trastuzumab is a monoclonal antibody selectively directed against Her2 and approved for the treatment of Her2 overexpressing breast cancer patients. Its proposed mechanisms of action include mediation of antibody-dependent cellular cytotoxicity (ADCC by triggering FcγRIII on natural killer (NK cells. This study addresses the correlation between overall NK function and trastuzumab's clinical activity. Subjects and methods Clinical and immunological responses were assessed in 26 patients receiving trastuzumab monotherapy as maintenance management after chemotherapy (8 mg/kg load and then standard doses of 6 mg/kg every 3 weeks. Cytotoxic activity against the MHC class I-negative standard NK target K562 cell line and HER2-specific ADCC against a trastuzumab-coated Her2-positive SKBR3 cell line were assessed in peripheral blood mononuclear cells (PBMC harvested after the first standard dose. After six months, seventeen patients were scored as responders and nine as non-responders according to the RECIST criteria, while Progression-Free Survival (PFS was calculated during a 12 months follow-up. Results The responders had significantly higher levels of both NK and ADCC activities (p Conclusion One of the mechanisms of action of trastuzumab is NK cell-mediated ADCC lysis of the Her2-positve target cell. We show here that its potency is correlated with the short-term response to treatment, whereas longer protection against tumor expansion seems to be mediated by pure NK activity.

    Measurement of residual disease following neoadjuvant chemotherapy that accurately predicts long-term survival in locally advanced breast cancer (LABC) is an essential requirement for clinical trials development. Several methods to assess tumor response have been described. However, the agreement between methods and correlation with survival in independent cohorts has not been reported. We report survival and tumor response according to the measurement of residual breast cancer burden (RCB), the Miller and Payne classification and the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, in 151 LABC patients. Kappa Cohen's coefficient (К) was used to test the agreement between methods. We assessed the correlation between the treatment outcome and overall survival (OS) and relapse-free survival (RFS) by calculating Harrell's C-statistic (c). The agreement between Miller and Payne classification and RCB classes was very high (К = 0.82). In contrast, we found a moderate-to-fair agreement between the Miller and Payne classification and RECIST criteria (К = 0.52) and RCB classes and RECIST criteria (К = 0.38). The adjusted C-statistic to predict OS for RCB index (0.77) and RCB classes (0.75) was superior to that of RECIST criteria (0.69) (P = 0.007 and P = 0.035, respectively). Also, RCB index (c = 0.71), RCB classes (c = 0.71) and Miller and Payne classification (c = 0.67) predicted better RFS than RECIST criteria (c = 0.61) (P = 0.005, P = 0.006 and P = 0.028, respectively). The pathological assessment of tumor response might provide stronger prognostic information in LABC patients.

    Full Text Available Objective: To study the correlation of serum LAG-3 and DKK-1 levels with cancer cell proliferation, invasion, angiogenesis and other clinical pathological characteristics in patients with gastric cancer. Methods: 48 patients who were diagnosed with early gastric cancer in our hospital between June 2014 and October 2016 were selected as the gastric cancer group of the research, 50 healthy volunteers who received physical examination in our hospital during the same period were selected as the control group of the research, serum was collected to determine the levels of lymphocyte activation gene-3 (LAG-3, Dickkopf-1 (DKK-1 and angiogenesis molecules, and the gastric cancer tissue and the tissue adjacent to carcinoma were collected to determine the expression of proliferation and invasion-related molecules. Results: Serum LAG-1, DKK-1, angiogenin-1 (Ang-1, Ang-2, vascular endothelial growth factor (VEGF and basic fibroblast growth factor (bFGF levels of gastric cancer group were significantly higher than those of control group (P<0.05, and EPHA2, LOXL2, PCNA, Akt, CyclinD1, MYH-9, CXCR7, KDM1A and CatB mRNA expression in gastric cancer tissue were significantly higher than those in the tissue adjacent to carcinoma (P<0.05; serum Ang-1, Ang-2, VEGF and bFGF levels as well as EPHA2, LOXL2, PCNA, Akt, CyclinD1, MYH-9, CXCR7, KDM1A and CatB mRNA expression in gastric cancer tissue of patients with gastric cancer were positively correlated with serum LAG-3 and DKK-1 levels. Conclusion: Serum LAG-3 and DKK-1 levels are valuable to diagnose early gastric cancer and can assess the cancer cell proliferation, invasion, angiogenesis and other clinical pathological characteristics in gastric cancer tissue.

    Full Text Available Objectives: To evaluate Ki67 immunoexpression pattern in Saudi breast cancer (BC patients and investigate any possible predictive or prognostic value for Ki67. Methods: This is a retrospective study designed to quantitatively assess the Ki67 proliferative index (PI in retrieved paraffin blocks of 115 Saudi BC patients diagnosed between January 2005 and March 2015 at the Department of Pathology, King Fahd Hospital, Al Madinah Al Munawarah, Kingdom of Saudi Arabia. The Ki67 PI was correlated with individual and combined immunoprofile data of estrogen receptor (ER, progesterone receptor (PR, and human epidermal growth factor receptor 2 (HER2/neu with their clinicopathological parameters. Results: Ki67 immunoreactivity was highly expressed (greater than 25% of the tumor cells were positive in 85 (73.9% patients. The Ki67 PI was significantly associated with poor prognostic clinicopathological parameters including old age (p less than 0.02, high tumor grade (p less than 0.01, lymph node metastasis (p less than 0.001, and Her-2/neu positivity (p less than 0.009. However, the association with ER positivity, PR positivity, tumor size, and lymphovascular invasion were not statistically significant. The Ki67 PI was significantly associated with BC molecular subtypes that were Her2/neu positive (luminal B and HER-2 subtypes compared with the Her2/neu negative (luminal A subtype (p less than 0.04. Conclusion: The Ki67 PI is significantly higher in Saudi BC patients comparing with the reported literature. Ki67 PI was highest in the HER-2 and luminal-B molecular subtypes. Along with other prognostic indicators, Ki67 PI may be useful in predicting prognosis and management of Saudi BC patients.

    Matrix metalloproteinase 11 (MMP11) has been shown to play a key role in human tumor progression and indicates poor clinical outcome in cancer patients. The current study aimed to evaluate the relationship between serum levels of MMP-11 and prognosis in colon cancer patients. Serum levels of MMP-11 were determined in 92 colon cancer patients and 92 healthy individuals using an enzyme-linked immunosorbent assay (ELISA). Associations between serum MMP-11 levels and clinicopathological characteristics of the patients and their outcomes were investigated. Survival analyses were performed to measure the 5-year overall survival (OS) and disease-free survival (DFS). Serum MMP-11 levels were substantially higher in colon cancer patients than in healthy controls. Moreover, serum MMP-11 levels were significantly higher in patients with advanced T status, lymph node metastasis, distant metastasis, and a higher TNM stage. Elevated serum levels of MMP-11 were identified as an independent prognostic factor for 5-year mortality and adverse events associated with colon cancer. Multivariate Cox regression analysis identified the serum MMP-11 level as an independent predictor of OS and DFS. Our study established that high serum levels of MMP-11 are associated with poor clinical outcome and may serve as a prognostic biomarker in colon cancer patients.

    Insulin and C-peptide levels were studied with a radioimmunoassay in the peripheral blood serum of 44 patients with gastric and cervical cancer and 22 healthy persons. Hyperfunction of the pancreatic insular apparatus was shown in cancer patients which was expressed in a statistically significant increase in the C-peptide level. In gastric cancer patients hyperfunction of the insular apparatus was accompanied by hypoinsulinemia, and in cervical cancer patients by hormoinsulinemia. An analysis has shown that the ratio insulin/C-peptide in gastric and cervical cancer patients was about the same and significantly lower than the control. A conclusion has been made that in spite of difference in the initial insulin concentration, the same phenomenon - acceleration of the metabolic clearance of insulin - occurs in patients with cancer of the above sites. The C-peptide level decreased, the ratio insulin/C-peptide increased, i.e. hyperfunction of the insular apparatus disappeared and the metabolic clearance of insulin slowed down

    Full Text Available BACKGROUND Lung cancer is the most common cancer worldwide since 1985, both in terms of incidence and mortality. Globally, lung cancer is the largest contributor to new cancer diagnoses and cancer-related deaths. The aim of the study is to study the clinical, radiological and pathological features of patients diagnosed with lung carcinoma. MATERIALS AND METHODS This observational and cross-sectional study was conducted at Himalayan Institute of Medical Sciences (HIMS, which is a large tertiary centre of Uttarakhand on 77 patients of proven lung carcinoma diagnosed over a period of February 2015 to March 2016. The clinical history of the patients was recorded in detail along with the radiological and pathological findings. Ethical clearance certificate was obtained from the ethical committee. RESULTS The study included a total of 77 patients of proven lung carcinoma. Out of the total patients, 70 were males and 7 were females. Cough was the most common symptom. Smoking was the commonest addiction (89.61% in the patients. Non-small cell carcinoma was seen in 59 patients while small cell carcinoma was seen in 23.38% of the cases. Amongst the total patients of non-small cell carcinoma, the maximum number of patients had squamous cell carcinoma (56%. CONCLUSION This study showed that smoking is a principle risk factor in causation of lung carcinoma. Lung cancer should be suspected in an old person presenting with cough and other symptoms such as malaise, weight loss etc. Squamous cell carcinoma is still the most common histological type of lung cancer in India.

    There was few study concentrated on the correlation between the evaluated tumor markers and lymph node metastasis. In this study, we aimed to evaluate the correlation between the CA724, CA242, CA199, CEA and the lymph node metastasis of gastric cancer and assess the prognostic value of them in different N stage patients. We analyzed the correlation between serum level of CA724, CA242, CA199, CEA and lymph node metastasis in 1501 gastric cancer patients. Lymph node metastasis of gastric cancer was related with tumor location, Bormann type, tumor size, histological type, depth of invasion and TNM stage (p CEA were positively correlated with the metastatic lymph node counts and the N stage (p tumor markers were higher (p tumor markers, the positive rates of tumor markers combination were higher. The combination of CA724 + CA242 + CA199 + CEA had highest positive rate. The higher CEA level related to N1 stage patients while higher CA199 was related with poor prognosis for N1 stage patients. For N0 and N2 stage patients, evaluation of CA724 indicated poorer prognosis. For N1 and N2 stage gastric patients, the patients with increased CA242 inclined to have shorter survival time. The tumor makers CA724, CA242, CA199 and CEA were evaluated significantly in the gastric patients with later N stage. The combination of these four tumor markers maybe prefer diagnostic index of gastric cancer and its lymph node metastasis. These tumor markers can be a possible indicator of poorer prognosis in different N stage patients.

    Full text: Prostate cancer is the third most common cancer among Peruvian males. Although radionuclide bone scans (BS) are frequently recommended as part of the staging evaluation for newly diagnosed prostate cancer, most scans are negative for metastases. It has been suggested that a routine bone scan is unnecessary in recently diagnosed prostate cancer if serum PSA is under 10 ng/mL. We hypothesized that Gleason score plus prostate-specific antigen (PSA), could predict for a positive bone scan (better that PSA alone), and that a low - risk group of patients could be identified in whom BS might be omitted. All patients who had both pathologic review of their prostate cancer biopsies and radionuclide BS at our institution from 1/93 to 12/95 were studied. Gleason score, PSA, and bone scan (Soloway Index) were determined in 165 patients. Bivariate analysis using chi (x2) was performed. The mean age of the 165 patients was 71.3 years, 109/165 (66.1%) had a 7-9 Gleason score and only 9/165 (5.5%) were well differentiated prostrate cancer. 82/165 (49.7%) had negative BS. When classifying patients according to their histological grade, the PSA median values were 11.8 ng/mL, 74.8 ng/mL and 116.4 ng/mL in well, median and poorly differentiated prostate cancer respectively. Using a cut off point of 10 ng/mL of PSA, the probability of having a positive BS in Gleason 7, 8 and 9 tumors were 0.109, 0.121 and 0.133 respectively. By using a cut off point of 20 ng/mL of PSA the possibility to have a positive BS in Gleason 7, 8 and 9 tumours were 0.182, 0.206 and 0.224 respectively. Gleason score plus PSA were independent predictors for a positive radionuclide BS in newly diagnosed prostate cancer patients. Considering that most of our patients have Gleason 7-9, the risk of bone metastases despite PSA levels between 10 - 20 ng/mL is not negligible. In our opinion, it is important to continue including bone scan in the staging assessment of prostate cancer. (author)

    The goal of this study was to assess the correlation between estrogen receptor (ER) status and histopathology findings, likewise to assess some selected prognostic factors in patients with breast cancer. The study was carried out on 126 patients with breast cancer. ER concentration was estimated by the standard biochemical assay (DCC-dextran-coated charcoal assay). The correlation between established risk factors like: lymph node status; age menopausal status and ER status were analysed.The ER yielded in 61% positive results. The mean value of ER in invasive ductal carcinoma was 43.9 fmol/mg protein and the mean value of ER in invasive lobular carcinoma 51.4 fmol/mg protein. The significant statistics negative correlation between ER status of pre-menopausal patients with ductal breast carcinoma and regional lymph nodes involvement was found. There was no difference between ER status and histological type of the cancer. No correlation was found between ER status and age of patients. (author)

    Full Text Available This study aimed to investigate the association between serum YKL-40 and prognosis of breast cancer in a Chinese population. Expression of YKL-40 of 120 Chinese patients with breast cancer and 30 controls (benign breast lesions was measured in tumor tissue by immunohistochemistry and in serum by ELISA. Differences in YKL-40 positivity grouped by specific patients' characteristics were compared using Pearson Chi-square test for rates of intratumoral staining, one-way ANOVA with a Bonferroni post-hoc comparison, or two-sample t-test for mean YKL-40 serum concentrations. Factors associated with overall survival were identified by univariate and multivariate cox-regression analyses. YKL-40 was elevated in approximately 75% of Chinese patients with breast cancer. A significantly higher percentage of patients with YKL-40 positive tumors had larger tumor size, higher TNM stage, and/or lymph node metastasis. Significantly higher mean YKL-40 serum concentrations were observed in patient subgroups with invasive lobular carcinoma (P<0.0167, higher TNM stage (P<0.001, and positive lymph node metastasis (P<0.001. The estimated mean survival time of patients with YKL-40 positive tumors was significantly shorter than for patients with YKL-40 negative tumors (55.13 months vs 65.78 months, P = 0.017. Multivariable Cox-regression analysis identified a significant association of overall survival time with YKL-40 serum concentration. Patients with YKL-40 positive tumors had significantly shorter disease free survival times than those with YKL-40 negative tumors. We propose that the potential utility of YKL-40 intratumoral staining or serum concentration as a biomarker for breast cancer is greatest within 5 years of diagnosis.

    Literature data indicate that mast cells (MCs) are involved in tumor angiogenesis due to the release of several pro-angiogenetic factors among which tryptase, a serine protease stored in MCs granules, is one of the most active. However, no data are available concerning the role of MCs in angiogenesis in primary human breast cancer. In this study, we have evaluated the correlations between the number of MCs positive to tryptase (MCDPT), the area occupied by MCs positive to tryptase (MCAPT) and microvascular density (MVD) and endothelial area (EA) in a series of 88 primary T1-3, N0-2 M0 female breast cancer, by means of immunohistochemistry and image analysis methods. Data demonstrated a significant (r = from 0.78 to 0.89; p-value from 0.001 to 0.002 by Pearson's analysis respectively) correlation between MCDPT, MCAPT, MVD, EA to each other. No correlation concerning MCDPT, MCAPT, MVD, EA and the main clinicopathological features was found. Our results suggest that tryptase-positive MCs play a role in breast cancer angiogenesis. In this context several tryptase inhibitors such as gabexate mesilate and nafamostat mesilate might be evaluated in clinical trials as a new anti-angiogenetic approach.

    Full Text Available OBJECTIVE: Diagnosis of breast cancer in young patients (≤35 correlates with a worse prognosis compared to their older counterparts (>35. The aim of this study is to evaluate the relevance of clinical-pathologic factors and prognosis in young (≤35 breast cancer patients. METHODS: One hundred thirty-two patients of operable breast cancer who were younger than 35 are analyzed in this study. They were treated in our hospital between January 2006 and December 2012. Patients are classified into four molecular subtypes based on the immunohistochemical profiles of estrogen receptor (ER, progesterone receptor (PR, human epidermal growth factor receptor 2 (HER2, and Ki-67. Clinical and pathologic factors have been combined to define a specific classification of three risk levels to evaluate the prognosis of these young women. RESULTS: Patients whose ages are less than 30 have poorer prognosis than patients whose ages are between 31 and 35. The status of lymph nodes post-surgery seems to be the only factor related to patient age in young patients. The patients in level of ER+ or PR+ and HER2−/+ status have the worst prognosis in hormone receptor–positive breast cancer. Group 3 in risk factor grouping has the poorer prognosis than the other two groups. CONCLUSIONS: Patient age and axillary lymph nodes post-surgery are the independent and significant predictors of distant disease-free survival, local recurrence-free survival, and overall survival. The absence of PR relates to poor prognosis. The risk factor grouping provides a useful index to evaluate the risk of young breast cancer to identify subgroups of patients with a better prognosis.

    To assess which laboratory and clinical factors are associated with fatigue in patients with terminal cancer. We evaluated 51 patients with advanced incurable solid tumors using the Chalder Fatigue Questionnaire (CFQ) and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale for fatigue; the Pittsburgh Sleep Quality Index (PSQI-BR) for sleep quality; the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression; the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire, Version 3.0 (QLQ C-30); and Functional Assessment of Cancer Therapy (FACT) for quality of life. We also analyzed several inflammatory markers and the modified Glasgow prognostic score (mGPS). We observed severe fatigue in 19 (38%) patients (FACIT-F score >36). There was a significant correlation between fatigue as evaluated by the CFQ and quality of sleep and between the CFQ mental fatigue subscale scores and TNF-α level. When fatigue was evaluated using the FACIT-F scale, we observed a significant association between fatigue and anxiety/depression, quality of sleep, mGPS, and hemoglobin levels. Fatigue measured both with the CFQ and FACIT-F scale correlated with poor quality of life according to the EORTC QLQ C-30. In patients with advanced cancer, fatigue is a common symptom associated with the presence of inflammation, poor quality of sleep, depression/anxiety, and poor quality of life. © The Author(s) 2015.

    Full Text Available Abstract Background Lack of knowledge regarding preventive health services for women might impede campaigns to expand these services in the emergency department setting. For 18–55-year-old English-speaking women visiting an urban emergency department, we aimed to: (1 Ascertain their knowledge regarding the applicability, purpose, and recommended intervals of three women's cancer screening and three contraceptive methods; and (2 Determine if patient age, race/ethnicity, medical insurance status, and current or recent usage of these methods are associated with greater or lesser knowledge about them. Methods Emergency department-based survey on recent or current usage and knowledge about Pap smears, breast self-examinations, mammograms, condoms, birth control, and emergency contraception. Analyses included calculation of summary statistics and creation of multivariable logistic regression models. Results Of 1,100 patients eligible for the study, 69.9% agreed to participate. Most of the participants were Conclusion Although these female ED patients demonstrated strong knowledge on some women's cancer screening and contraceptive methods, there were several areas of knowledge deficit. Women without private medical insurance and those who have not used a particular cancer screening or contraceptive method demonstrated less knowledge. Reduced knowledge about women's cancer screening and contraceptive methods should be considered during clinical encounters and when instituting or evaluating emergency department-based initiatives that assess the need for these methods.

    Objective: To study the effect of depression on Helicobacter pylori (H. pylori) infection in patients with gastric cancer and its correlation with oncogene expression. Methods: A total of 82 patients who accepted radical operation for gastric cancer in Zigong Third People's Hospital between March 2015 and February 2017 were selected as the research subjects and divided into depression group and non-depression group according to the preoperative HAMD scores, and helicobacter pylori infection as well as the mRNA expression of proliferation genes and invasion genes in gastric cancer lesions was detected. Results: The positive rate of H. pylori in gastric cancer lesions of depression group was significantly higher than that of non-depression group; LOXL2, RAB1A, UHRF1, Slug and ADAM8 mRNA expression in gastric cancer lesions of depression group were significantly higher than those of non-depression group while MTS1, NOX, E-cadherin and TIMP1 mRNA expression were significantly lower than those of non-depression group; LOXL2, RAB1A, UHRF1, Slug and ADAM8 mRNA expression in H. pylori-positive gastric cancer lesions of depression group were significantly higher than those in H. pylori-negative gastric cancer lesions of depression group while MTS1, NOX, E-cadherin and TIMP1 mRNA expression were significantly lower than those in H. pylori-negative gastric cancer lesions of depression group. Conclusion: Depression can increase the H. pylori infection rate and promote the proliferation and invasion of cancer cells in gastric cancer lesions.

    Full Text Available Circulating tumor cells (CTCs provide a non-invasive accessible source of tumor material from patients with cancer. The cellular heterogeneity within CTC populations is of great clinical importance regarding the increasing number of adjuvant treatment options for patients with metastatic carcinomas, in order to eliminate residual disease. Moreover, the molecular profiling of these rare cells might lead to insight on disease progression and therapeutic strategies than simple CTCs counting. In the present study we investigated the feasibility to detect KRAS, BRAF, CD133 and Plastin3 (PLS3 mutations in an enriched CTCs cell suspension from patients with colorectal cancer, with the hypothesis that these genes` mutations are of great importance regarding the generation of CTCs subpopulations. Subsequently, we compared CTCs mutational status with that of the corresponding primary tumor, in order to access the possibility of tumor cells characterization without biopsy. CTCs were detected and isolated from blood drawn from 52 colorectal cancer (CRC patients using a quantum-dot-labelled magnetic immunoassay method. Mutations were detected by PCR-RFLP or allele-specific PCR and confirmed by direct sequencing. In 52 patients, discordance between primary tumor and CTCs was 5.77% for KRAS, 3.85% for BRAF, 11.54% for CD133 rs3130, 7.69% for CD133 rs2286455 and 11.54% for PLS3 rs6643869 mutations. Our results support that DNA mutational analysis of CTCs may enable non-invasive, specific biomarker diagnostics and expand the scope of personalized medicine for cancer patients.

    To determine the correlation between pH and bicarbonate of soda in blood and saliva in child and adolescent patients during the administration of 3 g/m2 of methotrexate. A controlled clinical test was performed on 23 patients diagnosed with Acute Lymphoblastic Leukemia. Ages ranged from 4 to 18. The Spearman Correlation Coefficient was used to interpret the data. No significant correlation was found between pH levels and seric and salivary sodium bicarbonate. However, there was a significant correlation between the levels of sodium bicarbonate in the body fluids evaluated (rs 0.2576, p=0.0354). Changes modifying the microenvironment of the oral cavity probably do not allow saliva to be used to determine blood pH and seric bicarbonate.

    Purpose: Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) selectively induces apoptosis in cancer cells but not in normal cells, and a number of clinical trials have recently been initiated to test the safety and antitumoral potential of TRAIL in cancer patients. Four different receptors have been identified to interact with TRAIL: two are death-inducing receptors (TRAIL-R1 [DR4] and TRAIL-R2 [DR5]), whereas the other two (TRAIL-R3 [DcR1] and TRAIL-R4 [DcR2]) do not induce death upon ligation and are believed to counteract TRAIL-induced cytotoxicity. Because high levels of DcR2 expression have recently been correlated with carcinogenesis in the prostate and lung, this study investigated the importance of TRAIL and TRAIL receptor expression in breast cancer patients with invasive ductal carcinoma, taking various prognostic markers into consideration. Methods and Materials: Immunohistochemical analyses were performed on 90 breast cancer patients with invasive ductal carcinoma using TRAIL and TRAIL receptor-specific antibodies. Age, menopausal status, tumor size, lymph node status, tumor grade, lymphovascular invasion, perineural invasion, extracapsular tumor extension, presence of an extensive intraductal component, multicentricity, estrogen and progesterone receptor status, and CerbB2 expression levels were analyzed with respect to TRAIL/TRAIL receptor expression patterns. Results: The highest TRAIL receptor expressed in patients with invasive ductal carcinoma was DR4. Although progesterone receptor-positive patients exhibited lower DR5 expression, CerbB2-positive tissues displayed higher levels of both DR5 and TRAIL expressions. Conclusions: DR4 expression positively correlates with the tumor grade in breast cancer patients with invasive ductal carcinoma

    The objective of this study was to evaluate whether saliva production reflects the parotid volume during the course of radiation therapy (RT) in patients with head-and-neck cancer. Twenty patients with advanced oral squamous cell carcinomas, who were treated with preoperative chemo-RT, underwent morphological assessment with CT or MRI and functional assessment with the Saxon test. For the Saxon test, saliva production was measured by weighing a gauze pad before and 2 min after chewing without swallowing; the low-normal value is 2 g. Saliva production and parotid volumes before and 2 weeks after RT were compared with the paired t-test, the Spearman rank correlation test and the Fisher exact test. After 30 Gy irradiation, mean saliva production was decreased from 4.2 to 1.0 g (P 3 (P<0.01); the post-RT: pre-RT parotid volume ratio ranged from 54% to 85% (mean 71%). Although the initial parotid volume was correlated with initial saliva production (r=0.47, P=0.04), no significant correlation was noted after RT (r=0.08, P=0.71), and there were considerable individual variations. The parotid volume ratio was inversely correlated with the saliva-reduction amount (r=-0.79, P<0.01). There was a correlation between decreased parotid gland volume and decreased saliva production in patients with head-and-neck cancer undergoing RT. Parotid volume reduction may predict parotid gland function. (author)

  6. Expression of Foxp3 in colorectal cancer but not in Treg cells correlates with disease progression in patients with colorectal cancer.

    Full Text Available BACKGROUND: Regulatory T cells (Treg expressing the transcription factor forkhead-box protein P3 (Foxp3 have been identified to counteract anti-tumor immune responses during tumor progression. Besides, Foxp3 presentation by cancer cells itself may also allow them to evade from effector T-cell responses, resulting in a survival benefit of the tumor. For colorectal cancer (CRC the clinical relevance of Foxp3 has not been evaluated in detail. Therefore the aim of this study was to study its impact in colorectal cancer (CRC. METHODS AND FINDINGS: Gene and protein analysis of tumor tissues from patients with CRC was performed to quantify the expression of Foxp3 in tumor infiltrating Treg and colon cancer cells. The results were correlated with clinicopathological parameters and patients overall survival. Serial morphological analysis demonstrated Foxp3 to be expressed in cancer cells. High Foxp3 expression of the cancer cells was associated with poor prognosis compared to patients with low Foxp3 expression. In contrast, low and high Foxp3 level in tumor infiltrating Treg cells demonstrated no significant differences in overall patient survival. CONCLUSIONS: Our findings strongly suggest that Foxp3 expression mediated by cancer cells rather than by Treg cells contribute to disease progression.

    Objective: To analyze the differences between the social support for breast cancer patients and healthy female, and to explore the correlation between social support and quality of life (QOL) in the patients. Methods: From January 2013 to December 2014, 101 patients with operable breast cancer treated at Xinyu City People's Hospital were recruited as the experimental group. They completed questionnaires in the preoperative, postoperative chemoradiotherapy and rehabilitation periods, respectively.101 healthy female volunteers recruited from the community were included as control group, whose age and level of education were matched with those of the experimental group.The general questionnaire including basic information, disease conditions and other projects, perceived social support scale (PSSS), quality of life of breast cancer patients (FACT-B) were applied to evaluate the general situation, social support and QOL of the subjects. The differences in PSSS scores between the experimental and control groups were compared. The correlation between PSSS score and FACT-B score in the experimental group was analyzed. SPSS 18.0 software was used for statistical analysis. Results: The general situations of the experimental and control groups were comparable (all P >0.05). The rates of the total social support score ≥50 in the experimental and control groups were not significantly different (93.6% vs. 94.7%, P =0.067). Compared with that of the control group (23.2±4.8), the scores of family support in the experimental group in preoperative, postoperative chemoradiotherapy and rehabilitation periods were statistically higher (25.6±3.2, 24.2±4.2 and 24.0±3.4, respectively, P =0.034). The social support scores of patients with different demographic characteristics were different. Among the demographic characteristics, years of education and place of residence had the largest impact. The scores of social support in patients with longer education years and living in the

    Some authors suggest that adipocytokines contribute to the induction of pancreatic carcinogenesis as well as the development of endocrine insufficiency. We evaluate the circulating concentrations of leptin, resistin and visfatin in patients with newly diagnosed pancreatic cancer (PC) and relationship between serum adipocytokines level and clinicopathological features of PC. Moreover the usefulness of those adipocytokines as possible biomarkers of endocrine pancreatic function in PC has been assessed. The pilot study group consisted of 45 individuals (mean age 65.6 ± 11.5 years, BMI 21.8 ± 3.4 kg/m(2)) with newly diagnosed PC (within last 1-3 months) and 13 healthy individuals with age, gender and BMI matched to the study group. Among PC patients 18 (40%) had recently diagnosed diabetes. Fasting plasma leptin, resistin, visfatin concentrations were determined with ELISA (R&D Systems, Phoenix Pharmaceuticals) and insulin by RIA (DakoCytomation). Patients with PC as compared to controls had significantly lower plasma leptin (40.6 ± 21.3 vs 63.2 ± 16.3 pg/mL; p pancreatic cancer are characterized with lower level of leptin. This pilot study showed significantly higher resistin concentrations in patients with PC in comparison to healthy controls, which may be helpful in PC early diagnosis. Changes in leptin and resistin level in PC are not likely related to endocrine disorders. Copyright © 2013 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    Family caregivers of cancer patients become responsible for many elements of cancer care, usually without preparation or training in provision of care. Their efforts of care generate caregiving burden, which could deteriorate caregivers' quality of life (QOL). A secondary data analysis of a cross-sectional descriptive study was conducted to describe the influence of caregiving burden on the QOL of family caregivers of cancer patients with consideration of correlates (N = 212). The Korean versions of Zarit Burden Interview and the World Health Organization QOL BREF were used. Multiple regression analyses were applied to analyze the relationship between the caregiving burden and QOL. Caregiving burden explained 30.3% of variance of the QOL (β = -0.534, p < 0.001). Caregivers caring for patients with functional deterioration experienced higher burden. Caregivers providing care for hospitalized patients demonstrated lower QOL. The caregiver's educational level was a positively contributing factor for the QOL. Caregiving burden was the influential, negatively affecting factor for the QOL. Assessment of caregiving burden with special attention being paid to caregivers caring for patients with functional decline would help to identify caregivers in need of support. Supportive care needs to be sought to alleviate caregiving burden and improve the QOL of caregivers, especially for the caregivers of hospitalized patients. Copyright © 2015 Elsevier Ltd.

    The aim of this study was to evaluate the value of thyroglobulin (Tg) kinetics during preparation of radioiodine ablation for prediction of initial radioiodine ablation failure in thyroid cancer patients. Thyroid cancer patients after total thyroidectomy who underwent radioiodine ablation with 3–4 weeks of hormone withdrawal between May 2011 and January 2012 were included. Consecutive serum Tg levels 5–10 days before ablation (Tg1) and on the day of ablation (Tg2) were obtained. The difference between Tg1 and Tg2 (ΔTg), daily change rate of Tg (ΔTg/day) and Tg doubling time (Tg-DT) were calculated. Success of initial ablation was determined by the results of the follow-up ultrasonography, diagnostic radioiodine scan and stimulated Tg level after 6 to 20 months. A total of 143 patients were included. Failed ablation was reported in 52 patients. Tg2 higher than 5.6 ng/ml and Tg-DT shorter than 4.2 days were significantly related to a high risk of ablation failure. ΔTg and ΔTg/day did not show significant correlation with ablation failure. Thyroglobulin kinetics on consecutive blood sampling during hormone withdrawal may be helpful in predicting patients with higher risk of treatment failure of initial radioiodine ablation therapy in thyroid cancer patients.

    The study investigated the association between the location of transposed ovaries and posttreatment ovarian function in patients with early cervical cancer (IB1-IIA) who underwent radical hysterectomy and ovarian transposition with or without adjuvant therapies. Retrospective medical records were reviewed to enroll the patients with early cervical cancer who underwent ovarian transposition during radical hysterectomy at Samsung Medical Center between July 1995 and July 2012. Serum follicle-stimulating hormone (FSH) level was used as a surrogate marker for ovarian function. Twenty-one patients were enrolled. The median age and body mass index (BMI) were 31 years (range, 24-39 years) and 21.3 kg/m² (range, 17.7-31.2 kg/m²), respectively. The median serum FSH level after treatment was 7.9 mIU/mL (range, 2.4-143.4 mIU/mL). The median distance from the iliac crest to transposed ovaries on erect plain abdominal x-ray was 0.5 cm (range, -2.7 to 5.2 cm). In multivariate analysis, posttreatment serum FSH levels were significantly associated with the location of transposed ovaries (β = -8.1, P = 0.032), concurrent chemoradiation (CCRT) as an adjuvant therapy (β = 71.08, P = 0.006), and BMI before treatment (underweight: β = -59.93, P = 0.05; overweight: β = -40.62, P = 0.041). Location of transposed ovaries, adjuvant CCRT, and BMI before treatment may be associated with ovarian function after treatment. We suggest that ovaries should be transposed as highly as possible during radical hysterectomy to preserve ovarian function in young patients with early cervical cancer who might be a candidate for adjuvant CCRT and who have low BMI before treatment.

    Purpose: Head and neck cancers (HNCs) often induce profound immunosuppression, which contributes to disease progression and interferes with immune-based therapies. Body fluids of patients with HNC are enriched in exosomes potentially engaged in negative regulation of antitumor immune responses. The presence and content of exosomes derived from plasma of patients with HNC are evaluated for the ability to induce immune dysfunction and influence disease activity. Experimental Design: Exosomes were isolated by size-exclusion chromatography from plasma of 38 patients with HNC and 14 healthy donors. Morphology, size, numbers, and protein and molecular contents of the recovered exosomes were determined. Coculture assays were performed to measure exosome-mediated effects on functions of normal human lymphocyte subsets and natural killer (NK) cells. The results were correlated with disease stage and activity. Results: The presence, quantity, and molecular content of isolated, plasma-derived exosomes discriminated patients with HNC with active disease (AD) from those with no evident disease (NED) after oncologic therapies. Exosomes of patients with AD were significantly more effective than exosomes of patients with NED in inducing apoptosis of CD8 + T cells, suppression of CD4 + T-cell proliferation, and upregulation of regulatory T-cell (Treg) suppressor functions (all at P Exosomes of patients with AD also downregulated NKG2D expression levels in NK cells. Conclusions: Exosomes in plasma of patients with HNC carry immunosuppressive molecules and interfere with functions of immune cells. Exosome-induced immune suppression correlates with disease activity in HNC, suggesting that plasma exosomes could be useful as biomarkers of HNC progression.

    To examine the factors associated with hope and hopelessness in patients with cancer in Asian countries, and the instruments used to measure hope and hopelessness. A comprehensive systematic review was conducted with search terms, including cancer, hope, hopelessness and individual Asian country names, on CINAHL, Embase, PsycINFO, PubMed and Scopus databases. Only quantitative studies on adult cancer populations in Asia examining hope or hopelessness were included. A total of 2062 unique articles were retrieved from the databases, and 32 studies were selected for inclusion in this review. Hope and hopelessness were most frequently measured with the Herth Hope Index and the Mental Adjustment to Cancer Scale, respectively. The biopsychosocial factors that were most consistently associated with hope and hopelessness included sociodemographic variables (education, employment and economic status); clinical factors (cancer stage, physical condition and symptoms); and psychosocial factors (emotional distress, social support and connections, quality of life, control or self-efficacy, as well as adjustment and resilience). There is a need for more studies from South and Southeast Asia as most studies hailed from East Asia. This review highlighted the possibility of cultural differences influencing factors related to hope, suggesting that cross-cultural studies specifically would facilitate understanding behind these variations, although future reviews on hope should also include studies on hopelessness for a comprehensive understanding of the concept. Finally, more longitudinal research could be conducted to assess whether the factors associated with hope and hopelessness change over time and disease progression.

    Regular assessments of spiritual distress/spiritual pain among patients in a supportive/palliative care clinic (SCPC) are limited or unavailable. We modified the Edmonton Symptom Assessment Scale (ESAS) by adding spiritual pain (SP) to the scale (0 = best, 10 = worst) to determine the frequency, intensity, and correlates of self-reported SP (≥1/10) (pain deep in your soul/being that is not physical) among these advanced cancer patients. We reviewed 292 consecutive consults of advanced cancer patients (ACPs) who were evaluated at our SCPC between October of 2012 and January of 2013. Symptoms were assessed using the new instrument (termed the ESAS-FS). The median age of patients was 61 (range = 22-92). Some 53% were male; 189 (65%) were white, 45 (15%) African American, and 34 (12%) Hispanic. Some 123 of 282 (44%) of ACPs had SP (mean (95% CI) = 4(3.5-4.4). Advanced cancer patients with SP had worse pain [mean (95% CI) = 5.3(4.8, 5.8) vs. 4.5(4.0, 5.0)] (p = 0.02); depression [4.2(3.7, 4.7) vs. 2.1(1.7, 2.6), p well-being [5.4(4.9, 5.8) vs. 4.5(4.1, 4.9), p = 0.0136]; and financial distress (FD) [4.4(3.9, 5.0) vs. 2.2(1.8, 2.7), p Spiritual pain correlated (Spearman) with depression (r = 0.45, p well-being (r = 0.27, p = 0.0006), nausea (r = 0.29, p = 0.0002), and financial distress (r = 0.42, p Spiritual pain, which is correlated with physical and psychological distress, was reported in more than 40% of ACPs. Employment of the ESAS-FS allows ACPs with SP to be identified and evaluated in an SCPC. More research is needed.

    The aim of this study is to examine the demographic, medical, and social-cognitive correlates of objectively measured sedentary behavior in advanced cancer patients with brain metastases. Advanced cancer patients diagnosed with brain metastases, aged 18 years or older, cognitively intact, and with palliative performance scale greater than 30%, were recruited from a Rapid Access Palliative Radiotherapy Program multidisciplinary brain metastases clinic. A cross-sectional survey interview assessed the theory of planned behavior variables and medical and demographic information. Participants wore activPAL™ (PAL Technologies Ltd, Glasgow, United Kingdom) accelerometers recording time spent supine, sitting, standing, and stepping during 7 days encompassing palliative whole brain radiotherapy treatments. Thirty-one patients were recruited. Correlates of median time spent supine or sitting in hours per day were instrumental attitude (i.e., perceived benefits) of physical activity (r = -0.42; p = 0.030) and affective attitude (i.e., perceived enjoyment) of physical activity (r = -0.43; p = 0.024). Moreover, participants who sat or were supine for greater than 20.7 h per day reported significantly lower instrumental attitude (M = 0.7; 95% CI = 0.0-1.4; p = 0.051) and affective attitude (M = 0.7; 95% CI = 0.0-1.4; p = 0.041). Finally, participants who were older than 60 years of age spent more time sitting or being supine. Instrumental attitude and affective attitude were the strongest correlates of objectively measured sedentary behavior. This information could inform intervention studies to increase physical activity in advanced cancer patients with brain metastases. Copyright © 2014 John Wiley & Sons, Ltd.

    The isoflavone genistein, a natural soy product with receptor tyrosine kinase-inhibiting activity, as well as phytoestrogenic and other potential anticarcinogenic effects, is being studied as an anticancer agent. Since isoflavones are commonly consumed in food products containing soy proteins, a method to control for baseline isoflavone consumption is needed. HPLC was used to evaluate baseline plasma and urine concentrations of isoflavone in fifty-four participants with bladder cancer enrolled on a phase II chemoprevention study of G-2535. The soy food frequency questionnaire was used to assess participant's baseline soy intake. The association between baseline isoflavone concentrations and intakes for genistein and daidzein was assessed by the Spearman's rank correlation coefficient. The majority of participants had no detectable genistein or daidzein in plasma at baseline. The median and range of values were 0 (0-1480) nmol/L for genistein, and 0 (0-1260) nmol/L for daidzein. In urine, the median and range of values were 91.0 (0-9030) nmol/L for genistein and 623 (0-100,000) nmol/L for daidzein. The median and range of weekly estimated genistein intake was 0 (0-236) mg/wk; the median and range of weekly estimated daidzein intake was 0 (0-114) mg/wk. There was no relationship to soy intake as measured by the food frequency questionnaire and baseline isoflavone levels in plasma or urine and the Spearman's rank correlation coefficients were not significant. The soy food frequency questionnaire did not correlate with plasma or urine concentrations of either isoflavone. Alternative methods for controlling for soy consumption, including measuring plasma and urine concentrations, in isoflavone chemoprevention trials should be considered. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Colorectal cancer (CRC is a major burden of public health and healthcare worldwide. Microbiota has been suggested in promoting chronic inflammation in the intestine which, in turn, promotes tumor development. This study focuses on possible correlations of human papillomavirus (HPV infection with proinflammatory Stat3 signaling activities and the resulting levels of its downstream proinflammatory cytokine IL-17 in CRC patients.HPV was examined using HPV Genotyping Chip technology and constitutively active Stat3 (p-Stat3 and IL-17 levels were tested using immunohistochemistry (IHC in paraffin-embedded cancerous and adjacent normal tissues (ANT from a cohort of 95 CRC patients. Correlation analyses were performed between HPV infection and clinicopathological characteristics, Stat3 activities and IL-17 levels among these CRC patients.Three major findings were observed: (1 HPV infection existed in a high rate of CRC cases (48.4%, 46/95, of which 45 cases (45/46, 97.8% were high-risk HPV16-positive and only one case was HPV53-positive. (2 HPV infection correlated with poorer clinical stages (III+IV of CRC. (3 HPV infection strongly correlated with both constitutively higher Stat3 activities (P<0.01 and higher IL-17 levels (P<0.01 only in CRC tissues but not in ANT tissues.HPV infection is common in CRC patients suggesting potentially preventive effectiveness of HPV vaccination among high-risk young individuals. We have for the first time revealed a tri-lateral relationship among HPV infection, constitutive Stat3 activity and IL-17 level, whose collaborative act may orchestrate a proinflammatory microenvironment in the colorectum that, in turn, may promote carcinogenesis and possibly facilitate progression of CRC.

Mean volume; percentages of LSP volume absorbing 40, 50, 55, and 60 Gy (V30, V40, V50, V55, and V60 and point doses (P1, P2, P3, P4, P5, P6, P7, P8, P9, and P10; and RILSP incidence were calculated.Results: At 60 months of follow-up, four patients (8% were found to have grade 2/3 RILSP. The mean maximal LSP dose in patients with RILSP was 59.6 Gy compared with 53.9 Gy in patients without RILSP (control; P=0.04. The mean values of V40, V50, V55, and V60 in patients with RILSP versus control were 61.8% versus 52.8%, 44.4% versus 27.7%, 8.0% versus 0.3% and 1.8% versus 0%, respectively (P=0.01, 0.001, 0.001, and 0.001, respectively.Conclusion: The delineation of the LSP during IMRT planning may reduce the risk for RILSP. The mean values of V40, V50, V55, and V60 for LSP should be less than 55%, 30%, 5%, and 0.5%, respectively; however, further studies are warranted.Keywords: cervical cancer, intensity-modulated radiation therapy, lumbosacral plexus delineation, radiation-induced lumbosacral plexopathy, dosimetric analysis

    The purpose of our research was to determine the correlation of amplification, protein expression and somatic mutation of c-MET in IIIb-IV stage NSCLC (Non-small cell lung cancer). We also explored correlation of c-MET variation with clinical outcome. c-MET expression was observed in 28.6% (56/196) cases, and among those 13.8% (27/196) were shown to be FISH positive. Only 2.67% patients in this study carried the c-MET mutation. Cases with c-MET FISH positive were all IHC positive ,but in IHC positive cases, only half were FISH positive. Among patients with IHC 2+ staining, 35.5% was FISH positive, while cases with IHC 3+ staining,64% was FISH positive. Both protein expression and copy number of c-MET did not significantly correlate with clinical prognosis in these patients treated with EGFR-TKIs. IHC could be used as a preliminary screening method for c-MET copy number amplification and should be confirmed by FISH only in IHC positive case which facilitate selection of ALK or MET inhibitor therapy. c-MET gene copy number, protein expression and somatic mutation for exon 14 were detected by fluorescent- In-Situ -Hybridization (FISH), Immunohistochemistry (IHC), and Denaturing-High-Performance-Liquid-Chromatography (DHPLC), respectively, in 196 NSCLC patients. The relationship between c-MET abnormalities and clinical outcome of targeted therapy was analyzed by McNemar's test.

    The aim of our work was to investigate the use of a dynamic contrast-enhanced MR (DCEMR) technique for staging apparently localised pancreatic cancer, and to determine the patterns of tumour and vascular enhancement with this technique. Thirty-five consecutive patients were examined. The MR findings were correlated with surgical findings in 13 patients and with clinical outcome in 22 patients. Breath-hold gradient-echo fast low angle shot (TR = 100, TE = 4, flip angle 80 ) acquisitions were obtained at 10 and 40 s (right anterior coronal oblique plane) and at 90 s (axial plane) following intravenous gadolinium. Mean contrast-to-noise ratio was higher on the first than the second acquisition (p < 0.001) and higher on the second acquisition than the third (p < 0.005). Tumour conspicuity was greatest and arterial anatomy was best demonstrated on the first acquisition and the portal venous anatomy on the second. Small tumours were isointense by the third acquisition. Maximal intensity projections were helpful. The MR findings correctly predicted the surgical findings in 11 of 13 cases (85 %) and the clinical course in the other 22 patients. The DCEMR imaging technique is valuable in the staging of patients with pancreatic cancer. Capillary and portal venous phase images are both required for complete local staging. (orig.)

    Renal cell carcinoma is the most common highly metastatic kidney malignancy. Adhesion has a crucial role in the metastatic process. TGF (transforming growth factor)-β1 is a pleiotropic cytokine that influences cancerous transformation. We hypothesized that 1) changes in the expression of adhesion related genes may influence survival rate of patients with renal cell carcinoma and 2) TGF-β1 may contribute to changed expression of adhesion related genes. Two-step quantitative real-time polymerase chain reaction arrays were used to analyze the expression of adhesion related genes in 77 tumors and matched pair controls. The prognostic significance of genes was evaluated in TCGA (The Cancer Genome Atlas) data on 468 patients with renal cell carcinoma. Quantitative real-time polymerase chain reaction and Western blot were applied for TGF-β1 analysis. TGF-β1 mediated regulation of gene expression was analyzed by TGF-β1 supplementation of Caki-2 cells and quantitative real-time polymerase chain reaction. The expression of 19 genes related to adhesion and extracellular matrix remodeling was statistically significantly disturbed in renal cell carcinoma compared with controls. The 10-gene expression signature (COL1A1, COL5A1, COL11A1, FN1, ICAM1, ITGAL, ITGAM, ITGB2, THBS2 and TIMP1) correlated with poor survival (HR 2.85, p = 5.7e-10). TGF-β1 expression was 22 times higher in renal cell carcinoma than in controls (p adhesion and extracellular matrix remodeling develops early during renal cell carcinoma carcinogenesis and correlates with poor survival. TGF-β1 contributes to changed expression of extracellular matrix and adhesion related genes. Bioinformatic analysis performed on a broad panel of cancers of nonkidney origin suggests that disturbed expression of genes related to extracellular matrix and adhesion may be a universal feature of cancerous progression.

    Purpose: To validate the finding of an association between single nucleotide polymorphisms (SNPs) and toxicity during chemoradiotherapy (CRT) in rectal cancer patients, in an independent population. Methods and Materials: The cohort consisted of 165 patients who received CRT for rectal cancer from 2006 to 2012. Prospectively recorded toxicity information, graded according to the Common Terminology Criteria for Adverse Events version 3.0, was retrieved from the medical record. Additionally, a subset of 52 patients recorded their gastrointestinal symptoms weekly during CRT, using the 7-item Bowel Problems Scale. Deoxyribonucleic acid was extracted from normal tissue in the proctectomy specimens and screened for 3 SNPs: XRCC1 R399Q, XPD K751Q, and TGFβ1 R25P. Univariable and multivariable logistic regression models were constructed. Results: The median radiation dose was 50.4 Gy, and all patients received concurrent chemotherapy. Toxicities measured by the Common Terminology Criteria for Adverse Events were closely associated with patient-reported outcomes for the patients who completed the 7-item Bowel Problems Scale. Grade ≥3 toxicity occurred during CRT in 14 patients (8%). All 14 patients had either XRCC1 R399Q or TGFβ1 R25P polymorphisms. The TGFβ1 R25P polymorphism was significantly associated with grade ≥3 toxicity (odds ratio [OR] 3.47, P=.04) and, in patients who completed the Bowel Problems Scale, with grade ≥4 toxicity (OR 5.61, P=.02). The latter finding persisted in a multivariable logistic regression model controlling for ethnicity, age, and sex (adjusted OR 1.83, P=.02). Conclusions: We have validated the correlation between the TGFβ1 R25P SNP and acute toxicity during CRT in an independent cohort using both clinician- and patient-reported toxicity. The information from our study could be used as a basis to formulate a prospective trial testing the utility of this SNP as a biomarker of acute toxicity during neoadjuvant treatment in locally

    Differentiated thyroid cancers (DTCs) derive from thyroid follicular cells and include papillary and follicular cancers. In patients with DTCs, the initial treatment includes thyroidectomy and radioactive iodine (131-I) therapy. The objective of this study was to examine whether the intensity of DNA damage in peripheral blood lymphocytes (PBLs) of DTC patients depends on the amount of 131-I retained in the selected regions of interest (thyroid and abdominal region) as well as in the whole-body 72 hours after therapy. In addition, the possible influence of other factors that may affect micronuclei (MN) frequency, such as age, gender, smoking habits, and histological type of tumour was analyzed. The study population consisted of 22 DTC patients and 20 healthy donors. Data on the distribution of 131-I were obtained from the whole-body scans. MN frequency and cytokinesis-block proliferation index (CBPI) were measured using cytokinesis-block micronucleus assay. 131-I therapy significantly increased the MN frequency (19.50±6.90 vs. 27.10±19.50 MN) and significantly decreased the CBPI (1.52±0.20 vs. 1.38±0.17) in patients' lymphocytes. There was a clear correlation between the increased MN frequency and 131-I accumulation in the thyroid region in patients without metastases. The MN values did not differ in relation to the factors that could affect MN, such as age, gender, smoking habits, and histological type of tumour. In conclusion, the MN frequency in PBLs of DTC patients without metastases depends on the accumulation of 131-I in the thyroid region and does not depend on the other factors examined. (author)

    Full Text Available We investigated the HE4 variant-specific expression patterns in various normal tissues as well as in normal and malignant endometrial tissues. The relationships between mRNA variants and age, body weight, or survival are analyzed. ICAT-labeled normal and endometrial cancer (EC tissues were analyzed with multidimensional liquid chromatography followed by tandem mass spectrometry. Levels of HE4 mRNA variants were measured by real-time PCR. Mean mRNA levels were compared among 16 normal endometrial samples, 14 grade 1 and 14 grade 3 endometrioid EC, 15 papillary serous EC, and 14 normal human tissue samples. The relationship between levels of HE4 variants and EC patient characteristics was analyzed with the use of Pearson correlation test. We found that, although all five HE4 mRNA variants are detectable in normal tissue samples, their expression is highly tissue-specific, with epididymis, trachea, breast and endometrium containing the highest levels. HE4-V0, -V1, and -V3 are the most abundant variants in both normal and malignant tissues. All variants are significantly increased in both endometrioid and papillary serous EC, with higher levels observed in grade 3 endometrioid EC. In the EC group, HE4-V1, -V3, and -V4 levels inversely correlate with EC patient survival, whereas HE4-V0 levels positively correlate with age. HE4 variants exhibit tissue-specific expression, suggesting that each variant may exert distinct functions in normal and malignant cells. HE4 levels appear to correlate with EC patient survival in a variant-specific manner. When using HE4 as a biomarker for EC management, the effects of age should be considered.

    Background and purpose: Individual radiosensitivity is an inherent characteristic, associated with an increased reaction to ionizing radiation on the human body. Biological endpoints such as clonogenic survival, chromosome aberration formation and repair capacity of radiation-induced damage have been applied to evaluate individual radiosensitivity in vitro. 5%-7% of cancer patients develop adverse side effects to radiation therapy in normal tissues within the treatment field, which are referred as 'clinical radiation reactions' and include acute effects, late effects and cancer induction. It has been hypothesized that the occurrence and severity of these reactions are mainly influenced by genetic susceptibility to radiation. Additionally, the nature of the genetic disorders associated with hypersensitivity to radiotherapy suggests that DNA repair mechanisms are involved. Consequently, the characterization of DNA repair in lymphocytes through cytokinesis blocked micronucleus (MN) and alkaline single-cell micro gel electrophoresis (comet) assays could be suitable approaches to evaluate individual radiosensitivity in vitro. The MN assay is an established cytogenetic technique to evaluate intrinsic cell radiosensitivity in tumor cells and lymphocytes; comet assay is a sensitive and rapid method for measuring DNA damage and repair in individual cells. The aims of this study were: 1) To assess the in vitro radiosensitivity of peripheral blood lymphocytes from two groups of cancer patients (retrospectively and prospectively studied), using MN and comet assays, in comparison with the observed clinical response; and 2) To test the predictive potential of both techniques. Materials and methods: 38 cancer patients receiving radiation therapy were enrolled in this study. The tumor sites were: head and neck (n 25) and cervix (n = 13). Nineteen patients were evaluated about 6-18 month after radiotherapy (retrospective group) and 19 patients were evaluated prior, mid-way and on

    In human breast cancer, β-catenin localization has been related with disease prognosis. Since HER2-positive patients are an important subgroup, and that in breast cancer cells a direct interaction of β-catenin/HER2 has been reported, in the present study we have explored whether β-catenin location is related with the disease survival. The study was performed in a tumor bank from patients (n = 140) that did not receive specific anti-HER2 therapy. The proteins were detected by immunohistochemistry in serial sections, 47 (33.5%) patients were HER2-positive with a long follow-up. HER2-positive patients that displayed β-catenin at the plasma membrane (completely surrounding the tumour cells) showed a significant better disease-free survival and overall survival than the patients showing the protein on other locations. Then we explored the dynamics of the co-expression of β-catenin and HER2 in human MCF-7 and SKBR3 cells exposed to different stressful situations. In untreated conditions MCF-7 and SKBR3 cells showed very different β-catenin localization. In MCF-7 cells, cadmium administration caused a striking change in β-catenin localization driving it from plasma membrane to cytoplasmic and perinuclear areas and HER2 showed a similar localization patterns. The changes induced by cadmium were compared with heat shock, H2O2 and tamoxifen treatments. In conclusion, this study shows the dynamical associations of HER2 and β-catenin and their changes in subcellular localizations driven by stressful situations. In addition, we report for the first time the correlation between plasma membrane associated β-catenin in HER2-positive breast cancer and survival outcome, and the importance of the protein localization in breast cancer samples.

    Objective: To investigate the correlation between serum vascular endothelial growth factor(VEGF) level and CT perfusion parameters in patients with primary liver cancer (PLC) pre-and post-transcatheter arterial chemoembolization (TACE) treatment. Methods: Serum VEGF level was measured and CT perfusion imaging was performed 1 day before and 6 ∼ 8, 32 ∼ 40 days after TACE in 18 patients with PLC. Before and after TACE, the serum VEGF level, the tumor's artery liver perfusion (ALP), the portal vein perfusion (PVP) and the hepatic artery perfusion index (HPI) were measured pre-and post-TACE. The pre-TACE and post-TACE results were compared and statistically analyzed. Results: Based on the therapeutic results, the patients were divided into complete response (CR) group and partial response or stable disease(PR+SD) group. Although no significant difference in serum VEGF level, tumor's ALP, PVP and HPI existed between two groups pre-TACE, there was significant difference in ALP, HPI 6-8 days after TACE (P<0.05). Significant difference in serum VEGF level also existed in CR group (P<0.05), but not in (PR+SD) group, at (32-40) days post-TACE (P=0.221). The serum VEGF level carried a positive correlation with the tumor's ALP and HPI. Conclusion: The serum VEGF level can indirectly reflect the neovascularization of the tumor, while the CTPI can directly and quantitatively reflect the hemodynamic changes of the tumor post-TACE. Moreover, a positive correlation exists between serum VEGF level and ALP, HPI. Therefore, the determination of serum VEGF level together with CTPI is very useful in both evaluating TACE efficacy and making therapeutic schedule. (authors)

    Colorectal cancer (CRC) has been associated with high levels of lipid peroxidation, probably due to neoplasic tissue metabolism. Our objectives were to relate lipid peroxidation with the evolution of CRC and with various biomarkers (GGT, ALP, LDH, CEA) to assess its prognostic value. A longitudinal study was conducted with CRC patients (n=43), using FOLFOX4. At the end of the treatment, patients were grouped into two groups: poor outcome (PO) for those patients whose computed tomography showed signs of metastasis, not reduced or increased in the previous implants, and not reduced or increased in CEA levels and good outcome (GO) for the opposite trends. PO patients had a significant increase in TBARS levels, being different from other group in cycles 4, 5, and 6 of chemotherapy. After cycle 6 of chemotherapy, GO patients had higher SOD (27%) and catalase (33%) activity. TBARS levels showed a positive correlation with biomarkers at the beginning of the treatment, which disappeared after six cycles of chemotherapy, when TBARS levels of the PO group started to increase; the other parameters increased at a later time. Because the serum TBARS levels in GO patients did not increase after the beginning of chemotherapy, it is expected that the increase is not a result of the effects of chemotherapy but of sickness evolution. It is possible that the systemic assessment of lipid peroxidation might become an additional marker because it occurs earlier than other biomarkers and could therefore be useful in the prognosis of CRC patients.

    Epstein-Barr virus-associated gastric cancer (EBVaGC) is one of the four molecular subtypes of gastric cancer, as defined by the classification recently proposed by The Cancer Genome Atlas. We evaluated the correlation between EBV positivity and 18 F-fluorodeoxyglucose ( 18 F-FDG) uptake by positron emission tomography/computed tomography (PET/CT) in patients with gastric cancer. We retrospectively enrolled patients with gastric cancer who underwent pretreatment 18 F-FDG PET/CT and subsequent surgical resection, and then were diagnosed with advanced gastric cancer (pathologic stage ≥T2 with any N stage). Maximum standardized uptake values (SUV max ) of gastric cancer were measured by pretreatment 18 F-FDG PET/CT. EBV sequences were detected by in situ hybridization (ISH) techniques. We analyzed the correlation between EBV positivity, clinicopathologic features and metabolic activity of the primary tumor. A total of 205 patients were included and 15 (7.3%) patients were identified as having EBV-positive gastric cancer. Age, gender, tumor location, and histological type showed no significant differences between EBV-positive and negative groups. EBV-positive cancer is significantly more frequent in the higher-metabolic-tumor group than in the lower one (p=0.032). The mean SUV max of gastric cancers showed significant differences between EBV-positive and negative groups (9.9±4.2 vs. 7.0±4.8, p=0.026). The infection status of EBV was significantly related to the 18 F-FDG uptake of primary tumors in patients with advanced gastric cancer.

    To determine whether quantitative perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) correlate with immunohistochemical markers of angiogenesis in rectal cancer. Preoperative DCE-MRI was performed in 63 patients with rectal adenocarcinoma. Transendothelial volume transfer (K trans ) and fractional volume of the extravascular-extracellular space (Ve) were measured by Interactive Data Language software in rectal cancer. After surgery, microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression scores were determined using immunohistochemical staining of rectal cancer specimens. Perfusion parameters (K trans , Ve) of DCE-MRI in rectal cancer were found to be correlated with MVD and VEGF expression scores by Spearman's rank coefficient analysis. T stage and N stage (negative or positive) were correlated with perfusion parameters and MVD. Significant correlation was not found between any DCE-MRI perfusion parameters and MVD (rs = -0.056 and p 0.662 for K trans ; rs = -0.103 and p = 0.416 for Ve), or between any DCE-MRI perfusion parameters and the VEGF expression score (rs = -0.042, p 0.741 for K trans ; r = 0.086, p = 0.497 for Ve) in rectal cancer. TN stage showed no significant correlation with perfusion parameters or MVD (p > 0.05 for all). DCE-MRI perfusion parameters, K trans and Ve, correlated poorly with MVD and VEGF expression scores in rectal cancer, suggesting that these parameters do not simply denote static histological vascular properties.

    Farletuzumab (FAR) is a humanized monoclonal antibody (mAb) that binds to folate receptor alpha. A Ph3 trial in ovarian cancer patients treated with carboplatin/taxane plus FAR or placebo did not meet the primary statistical endpoint. Subgroup analysis demonstrated that subjects with high FAR exposure levels (Cmin>57.6μg/mL) showed statistically significant improvements in PFS and OS. The neonatal Fc receptor (fcgrt) plays a central role in albumin/IgG stasis and mAb pharmacokinetics (PK). Here we evaluated fcgrt sequence and association of its promoter variable number tandem repeats (VNTR) and coding single nucleotide variants (SNV) with albumin/IgG levels and FAR PK in the Ph3 patients. A statistical correlation existed between high FAR Cmin and AUC in patients with the highest quartile of albumin and lowest quartile of IgG1. Analysis of fcgrt identified 5 different VNTRs in the promoter region and 9 SNVs within the coding region, 4 which are novel. Copyright © 2017. Published by Elsevier Inc.

    Purpose: To evaluate postradiation regional heart perfusion changes with single photon emission tomography (SPECT) myocardial perfusion imaging in 69 patients treated with tangential photon beams radiation therapy (RT) for left-sided breast cancer. To correlate SPECT changes with percent irradiated left ventricle (LV) volume and risk factors for coronary artery disease (CAD). Methods and Materials: Rest SPECT of the LV was acquired pre-RT and at 6-month intervals post-RT. The extent of defects (%) with a severity > 1.5 standard deviations below the mean was quantitatively analyzed for the distributions of the left anterior descending (LAD) artery, left circumflex (LCX) artery, and right coronary artery (RCA) based on computer assisted polar map reconstruction (i.e., bull's-eye-view). Changes in perfusion were correlated with percent irradiated LV receiving > 25 Gy (range 0-32%). Data on patient- and treatment-related factors were collected prospectively (e.g., cardiac premorbidity, risk factors for CAD, chemotherapy, and hormonal treatment). Results: In the LAD distribution, there were increased perfusion defects at 6 months (median 11%; interquartile range 2-23) compared with baseline (median 5%; interquartile range 1-14) (p<0.001). There were no increases in perfusion defects in the LCX or RCA distributions. In multivariate analysis, the SPECT perfusion changes in the LAD distribution at 6 months were independently associated with percent irradiated LV (p<0.001), hormonal therapy (p=0.005), and pre-RT hypercholesterolemia (p=0.006). The SPECT defects in the LAD distribution at 12 and 18 months were not statistically different from those at 6 months. The perfusion defects in the LAD distribution were limited essentially to the regions of irradiated myocardium. Conclusion: Tangential photon beam RT in patients with left-sided breast cancer was associated with short-term SPECT defects in the vascular distribution corresponding to the radiation portals.

    The aim of this study was to evaluate the correlation between the residual tumor measured on magnetic resonance imaging and pathological results and to assess whether this correlation varies according to patient, tumor or chemotherapy characteristics. The study population included women treated for breast cancer with indication of neoadjuvant chemotherapy in our tertiary breast cancer Unit between January 2008 and December 2011. Factors related to patients, tumor and chemotherapy were studied. Pearson's correlation coefficient between the size of the tumor on MRI and pathological response was calculated for the entire population. It was also calculated according to patient, tumor and chemotherapy characteristics. During the study period, 107 consecutive women were included. The size of residual tumor on the MRI significantly correlated with the size on pathological result with a Pearson correlation coefficient of 0.52 (pcorrelation was stronger for women aged 50 years and older (r=0.64, pcorrelation was stronger for those with triple-negative tumors (r=0.69, p=0.002) but weaker for those with tumors with a ductal carcinoma in situ component (r =0.18, p=0.42). The size of breast cancer obtained by MRI is significantly correlated to the pathological size of the tumor. This correlation was stronger among women aged 50 years and more, among post-menopausal women, and among women who had triple-negative tumors.

    The majority of patients with pancreatic cancer who undergo curative resection experience rapid disease recurrence. In previous small studies, high expression of the mismatch-repair protein mutL protein homolog 1 (MLH1) in pancreatic cancers was associated with better outcomes. The objective of this study was to validate the association between MLH1 expression and survival in patients who underwent resection of pancreatic cancer and received adjuvant chemoradiation. Samples were obtained from the NRG Oncology Radiation Therapy Oncology Group 9704 prospective, randomized trial (clinicaltrials.gov identifier NCT00003216), which compared 2 adjuvant protocols in patients with pancreatic cancer who underwent resection. Tissue microarrays were prepared from formalin-fixed, paraffin-embedded, resected tumor tissues. MLH1 expression was quantified using fluorescence immunohistochemistry and automated quantitative analysis, and expression was dichotomized above and below the median value. Immunohistochemical staining was successfully performed on 117 patients for MLH1 (60 and 57 patients from the 2 arms). The characteristics of the participants who had tissue samples available were similar to those of the trial population as a whole. At the time of analysis, 84% of participants had died, with a median survival of 17 months. Elevated MLH1 expression levels in tumor nuclei were significantly correlated with longer disease-free and overall survival in each arm individually and in both arms combined. Two-year overall survival was 16% in patients who had low MLH1 expression levels and 53% in those who had high MLH1 expression levels (P MLH1 expression was correlated with long-term survival. Further studies should assess whether MLH1 expression predicts which patients with localized pancreatic cancer may benefit most from aggressive, multimodality treatment.

    Breast cancer is one of the most common female malignant tumors. The occurrence and development of breast cancer are often accompanied by abnormal gene expression. It has been well accepted that p53, Ki -67 are the commonly used biological indicators for clinical endocrine therapy and prognosis prediction. The oncogene expression reflects the malignant biological behavior of breast cancer from different perspectives. Those aggressive behaviors cause a variety of changes in histopathology and thus in imaging. Therefore, the imaging features of breast cancer may indirectly demonstrate the status of p53, Ki-67. Until now, because of its facility, low cost and high accuracy, mammography is still the preferred method in breast cancer screening and diagnosis. The relationship of mammographic appearances and gene expression in patients with breast cancer has potential clinical value in preoperative evaluation and planning of non-surgical treatment for those who are not able to perform immunohistochemistry.

    Background and purpose: There is a considerable hope among clinicians and radiobiologists to detect genetically radiosensitive patients prior to radiotherapy. A predictive assay would enable adjustment of the total irradiation dose to the individual at a constant risk of normal tissue complications. In this prospective study, the clonogenic survival assay for primary human fibroblasts to determine radiosensitivity in vitro was evaluated and then correlated with clinically observed acute radiation reactions. Materials and methods: One hundred twenty-five independent survival experiments with primary fibroblasts derived from 63 biopsies from 55 cancer and non-cancer patients were performed. Results: A wide variation of cell survival between biopsies was detected. Statistical analysis revealed a highly significantly larger interindividual than intraindividual variation of SF2 values. However, a considerable scatter of SF2 values in repeated experiments was observed in individual cases. Age, gender, disease status (cancer patient, non-cancer patient) and origin of fibroblasts (skin, periodontal tissue) were demonstrated not to be statistically significant confounding factors on the intrinsic radiosensitivity in vitro. In a prospective study, no correlation of the SF2 and acute reactions in 25 patients with head and neck cancer treated with a primary accelerated radiochemotherapy was detected. Conclusion: Our data show that the clonogenic assay is able to distinguish between intrinsic radiosensitivities of primary human fibroblasts if a statistical approach is used but does not predict acute radiation toxicity

    Patients with human epidermal growth factor receptor (HER)-2+ breast cancer are at particularly high risk for brain metastases; however, the biological basis is not fully understood. Using a novel HER-2 assay, we investigated the correlation between quantitative HER-2 expression in primary breast cancers and the time to brain metastasis (TTBM) in HER-2+ advanced breast cancer patients treated with trastuzumab. The study group included 142 consecutive patients who were administered trastuzumab-based therapy for HER-2+ metastatic breast cancer. HER-2/neu gene copy number was quantified as the HER-2/centromeric probe for chromosome 17 (CEP17) ratio by central laboratory fluorescence in situ hybridization (FISH). HER-2 protein was quantified as total HER-2 protein expression (H2T) by the HERmark® assay (Monogram Biosciences, Inc., South San Francisco, CA) in formalin-fixed, paraffin-embedded tumor samples. HER-2 variables were correlated with clinical features and TTBM was measured from the initiation of trastuzumab-containing therapy. A higher H2T level (continuous variable) was correlated with shorter TTBM, whereas HER-2 amplification by FISH and a continuous HER-2/CEP17 ratio were not predictive (p = .013, .28, and .25, respectively). In the subset of patients that was centrally determined by FISH to be HER-2+, an above-the-median H2T level was significantly associated with a shorter TTBM (hazard ratio, [HR], 2.4; p = .005), whereas this was not true for the median HER-2/CEP17 ratio by FISH (p = .4). Correlation between a continuous H2T level and TTBM was confirmed on multivariate analysis (HR, 3.3; p = .024). These data reveal a strong relationship between the quantitative HER-2 protein expression level and the risk for brain relapse in HER-2+ advanced breast cancer patients. Consequently, quantitative assessment of HER-2 protein expression may inform and facilitate refinements in therapeutic treatment strategies for selected subpopulations of patients in this

    To examine the relationship between metabolic features of purine nucleotides and antioxidant system depending on the age of patients with colorectal cancer. The activity of adenosine deaminase, xanthine oxidase, glutathione peroxidase, superoxide dismutase and glucose-6-phosphate dehydrogenase, the NOx concentration and the oxidative modification of proteins were determined spectrophotometricaly in 50 apparently healthy people and 26 patients with colorectal cancer stage -III---IV, aged 40 to 79 years. Increase of pro-oxidant system of erythrocytes with the age against decrease in level of antioxidant protection in both healthy individuals and colorectal cancer patients was determined. A significant increase of pro-ducts of oxidative proteins modification in erythrocytes with ageing was shown. Statistically significant correlation between enzymatic and non enzymatic markers pro-oxidant system and the activity of antioxidant defense enzymes in erythrocytes of patient with colorectal cancer was determined. Obtained results have demonstrated the imbalance in the antioxidant system of erythrocytes in colorectal cancer patients that improve the survival of cancer cells that is more distinctly manifested in ageing.

    Incapacitating symptom burden in cancer patients contributes to poor quality of life (QOL) and can influence treatment outcomes because of poor tolerance to therapy. In this study, the role of circulating cytokines in the production symptoms in cancer patients is evaluated. Eighty patients with metastatic colorectal cancer with either normal (group I, n = 40) or dampened (group II, n = 40) 24-hour rest/activity patterns measured by actigraphy were identified. Actigraphy patterns were correlated with QOL indices, serum cortisol obtained at 8:00 a.m. and 4:00 p.m. and with serum levels of transforming growth factor-alpha, tumor necrosis factor-alpha, and interleukin 6 (IL-6) obtained at 8:00 a.m. and analyzed in duplicate by ELISA. Cytokine levels and survival were also correlated. Group II patients had significantly higher pre treatment levels of all three cytokines, displayed significantly poorer emotional and social functioning, had higher fatigue, more appetite loss, and poorer performance status compared with group I patients. Transforming growth factor-alpha (TGF-alpha) and IL-6 were significantly increased in the patients with WHO performance status >1 and in those with appetite loss. Fatigue was significantly associated with elevated TGF-alpha only. IL-6 was increased in those patients with extensive liver involvement and multiple organ replacement, and it was significantly correlated with dampened cortisol rhythm. In a multivariate analysis, IL-6 was correlated with poor treatment outcome. Significant correlations were found between serum levels of TGF-alpha and IL-6, circadian patterns in wrist activity and serum cortisol and tumor-related symptoms in patients with metastatic colorectal cancer. These data support the hypothesis that some cancer patient's symptoms of fatigue, poor QOL, and treatment outcome are related to tumor or host generated cytokines and could reflect cytokine effects on the circadian timing system. This interplay between cytokine

    Objective: To discuss the effect of psychological intervention on the heart rate, systolic pressure of the patients with cervical cancer who are treated with interventional chemoembolization. Methods: Eighty patients with cervical cancer were randomly and equally divided into two groups. Transcatheter arterial chemoembolization (TACE) was performed in all cases. Patients in study group (n=10) received systemic psychological intervention 30 minutes before TACE. The heart rate and systolic pressure of the patients were measured when TACE started. The results were compared with that obtained at the time of admission. Patients in control group (n=10) did not receive systemic psychological intervention before TACE and their heart rate and systolic pressure were measured in the same way as in study group. Results: At the time TACE started the heart rate and systolic pressure of the patients in study group were significantly lower than that in control group (P < 0.05). Conclusion: Preoperative psychological intervention is very helpful for reducing psychological stress and mental tension,in stabilizing heart rate and systolic pressure of the patients with cervical cancer who are treated with TACE.

    Purpose: To determine the importance of downstaging of locally advanced rectal cancer after neoadjuvant treatment. Methods and Materials: The study included all consecutive patients with locally advanced rectal cancer who underwent neoadjuvant treatment (chemotherapy and/or radiotherapy) in different Italian centers from June 1996 to December 2003. A novel score was used, calculated as the sum of numbers obtained by giving a negative or positive point, respectively, to each degree of increase or decrease in clinical to pathologic T and N status. Results: A total of 317 patients were eligible for analysis. Neoadjuvant treatments performed were as follows: radiotherapy alone in 75 of 317 patients (23.7%), radiotherapy plus chemotherapy in 242 of 317 patients (76.3%). Worse disease-free survival was observed in patients with a lower score (Score 1 = -3 to +3 vs. Score 2 = +4 to +7; p = 0.04). Conclusions: Our results suggest that a novel score, calculated from preoperative and pathologic tumor and lymph node status, could represent an important parameter to predict outcome in patients receiving neoadjuvant treatment for rectal cancer. The score could be useful to select patients for adjuvant chemotherapy after neoadjuvant treatment and surgery.

    Full Text Available Background: Tumor-infiltrating lymphocytes (TILs are emerging as biomarkers mediating tumor response to treatments. Earlier studies have provided evidence that the level of TILs has prognostic value, particularly in triple-negative and human epidermal growth factor receptor-2-positive breast cancer. Moreover, the level of TILs has been associated with treatment outcome in patients undergoing neoadjuvant chemotherapy, and there is a strong correlation with pathologically complete response. In this study, we analyzed whether changes in TILs take place after neoadjuvant therapy and if they correlate with pathological response to treatment. Patients and Methods: We retrospectively analyzed the specimen slides from the Department of Anatomic Pathology of H. Adam Malik General Hospital during 2011–2015. We identified 51 patients fulfilling the inclusion criteria of this study. The histological sections had already been evaluated by hematoxylin and eosin slides. They were reassessed by our pathologist for the percentage of intratumoral and stromal TILs. The correlation with pathological response of the tumor after neoadjuvant therapy was also studied in these patients. Each case was also defined as high- or low-TIL breast cancer adopting previously validated cutoffs. Results: The mean age of the 51 patients was 49.22 years. The most frequent type of breast cancer histology was invasive ductal breast carcinoma in 49 (96% patients, and there were 2 (4% patients with lobular carcinoma. The histopathological grading for high TILs was grade 1 in 5 patients, grade 2 in 15 patients, and grade 3 in 3 patients. High TILs that had a pathologically complete response were found in 47.8% of patients, and low TILs were found in 28.8%. There was no significant correlation between TILs and pathological response in patients with neoadjuvant chemotherapy (p = 0.157. Conclusions: This research has not been able to demonstrate a significant correlation between TILs and

    Caregiver, relational, and patient factors have been associated with the health of family members and friends providing care to patients with early-stage cancer. Little research has examined whether findings extend to family caregivers of patients with incurable cancer, who experience unique and substantial caregiving burdens. We examined correlates of mental and physical health among caregivers of patients with newly-diagnosed incurable lung or non-colorectal gastrointestinal cancer. At baseline for a trial of early palliative care, caregivers of participating patients (N = 275) reported their mental and physical health (Medical Outcome Survey-Short Form-36); patients reported their quality of life (Functional Assessment of Cancer Therapy-General). Analyses used hierarchical linear regression with two-tailed significance tests. Caregivers' mental health was worse than the U.S. national population (M = 44.31, p caregiver, relational, and patient factors simultaneously revealed that younger (B = 0.31, p = .001), spousal caregivers (B = -8.70, p = .003), who cared for patients reporting low emotional well-being (B = 0.51, p = .01) reported worse mental health; older (B = -0.17, p = .01) caregivers with low educational attainment (B = 4.36, p family caregivers of patients with incurable cancer, caregiver demographics, relational factors, and patient-specific factors were all related to caregiver mental health, while caregiver demographics were primarily associated with caregiver physical health. These findings help identify characteristics of family caregivers at highest risk of poor mental and physical health who may benefit from greater supportive care.

    Our objective was to assess longitudinal health-related quality of life (HRQoL) in patients treated with radiotherapy for gynecologic malignancy and assess the relationship of psychosocial encounters on HRQoL. Women with gynecologic malignancy were prospectively enrolled and HRQoL assessed before, during, and after radiotherapy treatment using validated measures. Treatment and demographic information were reviewed. Mixed-effects models were used to assess changes in quality of life (QoL) over time and association of psychologist and social worker encounters with overall QoL as well as subdomains of QoL. Fifty-two women were enrolled and 41 completed at least one assessment. Fatigue (p = 0.008), nausea (p = 0.001), feeling ill (p = 0.007), and being bothered by side effects (p < 0.001) worsened on treatment with subsequent improvement. By follow-up, patients reported increased functional well-being (FWB) with significant decrease in worry (p = 0.003), increase in enjoyment of things usually done for fun (p = 0.003) and increase in contentment (p = 0.047). Twenty-three patients had at least one interaction with a social worker or psychologist during treatment. Each additional interaction was associated with a 2.12 increase in FWB score from before to after treatment (p = 0.002), and 1.74 increase from on to after treatment (p = 0.011). Additional interactions were not significantly associated with changes in overall FACT score (p = 0.056) or SWB (p = 0.305). Patient-reported HRQoL significantly worsened during radiotherapy treatment with subsequent improvement, affirming transiency of treatment-induced toxicities. Our preliminary study suggests that clinically-recommended psychological and social work interventions have potential value with respect to improving patient QoL during radiotherapy. Larger studies are needed to validate our findings

    Objective: To investigate the features of apparent diffusion coefficient (ADC) histogram parameters based on entire tumor volume data in high resolution diffusion weighted imaging of nasopharyngeal carcinoma (NPC) and to evaluate its correlations with cancer stages. Methods: This retrospective study included 154 cases of NPC patients[102 males and 52 females, mean age (48±11) years]who had received readout segmentation of long variable echo trains of MRI scan before radiation therapy. The area of tumor was delineated on each section of axial ADC maps to generate ADC histogram by using Image J. ADC histogram of entire tumor along with the histogram parameters-the tumor voxels, ADC(mean), ADC(25%), ADC(50%), ADC(75%), skewness and kurtosis were obtained by merging all sections with SPSS 22.0 software. Intra-observer repeatability was assessed by using intra-class correlation coefficients (ICC). The patients were subdivided into two groups according to cancer volume: small cancer group (histogram parameters and cancer stages was evaluated with Spearman test. Results: The ICC of measuring ADC histogram parameters of tumor voxels, ADC(mean), ADC(25%), ADC(50%), ADC(75%), skewness, kurtosis was 0.938, 0.861, 0.885, 0.838, 0.836, 0.358 and 0.456, respectively. The tumor voxels was positively correlated with T staging ( r =0.368, P histogram (ADC(mean), ADC(25%), ADC(50%)) increases with T staging in NPC smaller than 2 cm(3).

    Higher background parenchymal enhancement (BPE) could be used for stratification of MRI screening programs since it might be related to a higher breast cancer risk. Therefore, the purpose of this study is to correlate BPE to patient and tumor characteristics in women with unilateral MRI-screen detected breast cancer who participated in an intermediate and high risk screening program. As BPE in the affected breast may be difficult to discern from enhancing cancer, we assumed that BPE in the contralateral breast is a representative measure for BPE in women with unilateral breast cancer. This retrospective study was approved by our local institutional board and a waiver for consent was granted. MR-examinations of women with unilateral breast cancers screen-detected on breast MRI were evaluated by two readers. BPE in the contralateral breast was rated according to BI-RADS. Univariate analyses were performed to study associations. Observer variability was computed. Analysis included 77 breast cancers in 76 patients (age: 48±9.8 years), including 62 invasive and 15 pure ductal carcinoma in-situ cases. A negative association between BPE and tumor grade (p≤0.016) and a positive association with progesterone status (p≤0.021) was found. The correlation was stronger when only considering invasive disease. Inter-reader agreement was substantial. Lower BPE in the contralateral breast in women with unilateral breast cancer might be associated to higher tumor grade and progesterone receptor negativity. Great care should be taken using BPE for stratification of patients to tailored screening programs.

    Transforming growth factor-β (TGF-β), interleukin-10 (IL-10), and forkhead box P3 (Foxp3) have important roles in breast cancer development. Previous studies confirmed a correlation between these immune molecules and tumor characteristics, but their association with nutritional status in breast cancer is largely unknown. We aimed to investigate the association between body mass index (BMI), hemoglobin, total protein, albumin, globulin (GLB), albumin/GLB ratio (AGR), pre-albumin, prognostic nutritional index, and TGF-β, IL-10, and Foxp3 mRNA expression in patients with breast cancer. Quantitative real-time PCR was used to detect the mRNA expression of TGF-β, IL-10, and Foxp3 in the peripheral blood of 107 patients with breast cancer and 21 healthy controls. We found that TGF-β mRNA levels were 2.6-fold, 3.2-fold, and 2.3-fold higher in patients with low BMI (BMI (BMI BMI ≥ 25), respectively (P BMI, may strongly affect systematic immune function in patients with breast cancer. © 2018 IUBMB Life, 70(3):237-245, 2018. © 2018 International Union of Biochemistry and Molecular Biology.

    To explore the correlation between the width of lingual varix and changes of hemodynamics of portal system in patients with primary liver cancer so as to supply the data for the forecast of portal hypertension by observing lingual varix. The diameter of lingual vein (Dlv) was measured by vernier caliper as dependent variable, and the diameters and indexes of hemodynamics of portal vessels were measured by Doppler as independent variables, then a multipe stepwise analysis was performed. The diameters of portal vein (Dpv) and splenic vein (Dsv) entered the formula Dlv (mm) = 0.185 + 0.311 Dsv (mm) + 0.236 Dpv (mm) when the entry and removal values were alpha(in)=0.10 and alpha(out)=0.15, respectively. The width of lingual vein is closely correlated with the diameters of portal vein and splenic vein in patients with primary liver cancer.

    Pms2 protein is a component of the DNA mismatch repair complex responsible both for post-replication correction of DNA nucleotide mispairs and for early steps in apoptosis. Germline mutations in DNA mismatch repair genes give rise to hereditary non-polyposis colon cancer, which accounts for about 4% of colon cancers. However, little is known about the expression of mismatch repair proteins in relation to sporadic colon cancer, which accounts for the great majority of colon cancers. Multiple samples were taken from the non-neoplastic flat mucosa of colon resections from patients with no colonic neoplasia, a tubulovillous adenoma, or an adenocarcinoma. Expression of Pms2 was assessed using semiquantitative immunohistochemistry. Apoptosis was assessed in polychrome-stained epoxy sections using morphologic criteria. Samples from patients without colonic neoplasia had moderate to strong staining for Pms2 in cell nuclei at the base of crypts, while samples from 2 of the 3 colons with a tubulovillous adenoma, and from 6 of the 10 colons with adenocarcinomas, showed reduced Pms2 expression. Samples from patients with an adenocarcinoma that had reduced Pms2 expression also exhibited reduced apoptosis capability in nearby tissue samples, evidenced when this paired tissue was stressed ex vivo with bile acid. Reduced Pms2 expression in the colonic mucosa may be an early step in progression to colon cancer. This reduction may cause decreased mismatch repair, increased genetic instability, and/or reduced apoptotic capability. Immunohistochemical determination of reduced Pms2 expression, upon further testing, may prove to be a promising early biomarker of risk of progression to malignancy.

    Local immunological factors are thought to be parenchymal reaction of normal and tumor tissues. Those were studied by morphological changes of angiographic findings and histological methods which included photomicroscopic, electromicroscopic and enzymic-histochemical studies. It was demonstrated that the effect of radiotherapy depended on not only local blood supply but also parenchymal reaction of the host. Especially, the parenchymal reaction at 2000 or 3000 rad irradiation was regarded as nonspecific tissue repair as well as immunological protective reactions brought about by enhancement of the tumor antigenicity. It was proved that T-cell system played a main role in this parenchymal reaction. Changes of systemic immunological factors were studied in 17 laryngeal cancer and 80 lung cancer patients treated by radiotherapy alone or radiotherapy with combined chemotherapy. Due to the fact that damages of the host before treatment were not so serious and integral dose given to the patients was a little in cases of laryngeal cancer immunological parameters such as absolute lymphocyte counts, PHA and PPD skin test activities, lymphocyte blastoid transformation with PHA, PWM and Con A, did not show significant change. However, as for lung cancer treated by large integral dose irradiation combined with chemotherapy, immunological parameters were depressed in inverse proportion to the dose of irradiation and chemotherapeutic agents. Moreover T-cell subsets (early E-rosette forming cells, IgG Fc-receptor positive cells), lymphocyte sub-populations, ADCC activity, serum immunoglobulins, and serum protein were also investigated in cases of lung cancer. We have evaluated the immunological parameters in relation to the therapeutic effect. As a result, it was suggested that several parameters should be needed to forecast the prognosis. (author)

    Many breast cancer patients gain weight during chemotherapy and antiestrogenic treatment increasing recurrence, oncologic specific and all-cause mortality risks. Patients and Methods: 165 ER+/PR±/HER2- breast cancer patients under antiestrogenic treatment were randomly assigned to follow an at-home diet based on food naturally high in proteins, calcium, probiotics and prebiotics (D), or this diet and 4' isometric exercises (D+Ex) for 1 year. We measured weight (W), body (BF) and visceral fat (VF) using a multi-frequency bioelectrical impedance scale on the 6th and 12th month and we correlated results with chemotherapy, surgery and antiestrogenic medication type. Results were analysed using the Friedman Test, then with Wilcoxon signed-rank tests if Friedman Test was significant. Results: Overall, the patients 1-year results show that both D+Ex and D patients obtained statistically significant weight loss and fat loss. D patients lost 3.3 kg, 3.2% BF and 1% visceral fat. D+Ex patients lost 6.5 kg, 3.3% BF and 2% visceral fat. D+Ex patients obtained statistically significance for W, BF and VF regardless of chemotherapy, surgery or antiestrogenic treatment type. D patients with mastectomy or with aromatase inhibitors lost W, BF and VF. D patients with conservatory surgery, adjuvant or both neoadjuvant and adjuvant chemotherapy and those on Tamoxifen only lost W. D patients with neoadjuvant chemotherapy also lost VF. This diet is effective for ER+/PR±/HER2- breast cancer patients on antiestrogenic medication. Adding at least a minimal exercise protocol improves patients chances of counteracting sarcopenic obesity. Celsius.

    Purpose: Aim of this study was to correlate dose to pharyngeal constrictors (PC) with subjective and observer-based assessments of swallowing in patients with head and neck cancer undergoing concomitant chemo-IMRT. Materials and methods: Dose-volume histograms (DVHs) for superior constrictor (SC), middle constrictor (MC) and inferior constrictor (IC) were generated for 37 patients. Mean doses to SC, MC and IC were correlated to objective dysphagia grade (1 year, RTOG scoring) and global, total physical (TP) and most relevant components of the physical section (P6, P8) of the MD Anderson dysphagia inventory (MDADI) which was evaluated post-treatment. Odds ratios of dysphagia (>grade 0), poor global (<3), TP (<32), P6 (<3) and P8 (<3) for patients with mean dose > 60 Gy to SC and IC were calculated. Results: There was no significant correlation between mean dose to PC and any of the analysed MDADI parameters and observer-assessed dysphagia grade. Odds ratio of dysphagia (>grade 0), poor global (<3), TP (<32), P6 (<3) and P8 (<3) for patients with mean dose > 60 Gy to IC and SC were not significantly higher than those for patients receiving <60 Gy. Conclusion: This study did not find a statistically significant correlation between radiation dose to the PC and observer-assessed dysphagia grade or patient-reported MDADI questionnaire at 1 year.

    The aromatase inhibitors (AI) exemestane (EXE), letrozole (LET), and anastrozole suppress estrogen biosynthesis, and are effective treatments for estrogen receptor (ER)-positive breast cancer. Prior work suggests that anastrozole blood concentrations are associated with the magnitude of estrogen suppression. The objective of this study was to determine whether the magnitude of estrogen suppression, as determined by plasma estradiol (E2) concentrations, in EXE or LET treated patients is associated with plasma AI concentrations. Five hundred post-menopausal women with ER-positive breast cancer were enrolled in the prospective Exemestane and Letrozole Pharmacogenetic (ELPh) Study conducted by the COnsortium on BReast cancer phArmacogomics (COBRA) and randomly assigned to either drug. Estrogen concentrations were measured at baseline and after 3 months of AI treatment and drug concentrations were measured after 1 or 3 months. EXE or LET concentrations were compared with 3-month E2 concentration or the change from baseline to 3 months using several complementary statistical procedures. Four-hundred patients with on-treatment E2 and AI concentrations were evaluable (EXE n = 200, LET n = 200). Thirty (7.6%) patients (EXE n = 13, LET n = 17) had 3-month E2 concentrations above the lower limit of quantification (LLOQ) (median: 4.75; range: 1.42-63.8 pg/mL). EXE and LET concentrations were not associated with on-treatment E2 concentrations or changes in E2 concentrations from baseline (all p > 0.05). Steady-state plasma AI concentrations do not explain variability in E2 suppression in post-menopausal women receiving EXE or LET therapy, in contrast with prior evidence in anastrozole treated patients.

    Background and purpose: Individual radiosensitivity is an inherent characteristic, associated with an increased reaction to ionizing radiation on the human body. Biological endpoints such as clonogenic survival, chromosome aberration formation and repair capacity of radiation-induced damage have been applied to evaluate individual radiosensitivity in vitro. 5%-7% of cancer patients develop adverse side effects to radiation therapy in normal tissues within the treatment field, which are referred as 'clinical radiation reactions' and include acute effects, late effects and cancer induction. It has been hypothesized that the occurrence and severity of these reactions are mainly influenced by genetic susceptibility to radiation. Additionally, the nature of the genetic disorders associated with hypersensitivity to radiotherapy suggests that DNA repair mechanisms are involved. Consequently, the characterization of DNA repair in lymphocytes through cytokinesis blocked micronucleus (MN) and alkaline single-cell micro...

    Purpose: The purpose of this study was to quantify the effects of four-dimensional computed tomography (4DCT), 4D image guidance (4D-IG), and beam gating on calculated treatment field margins in a lung cancer patient population. Materials and Methods: Images were acquired from 46 lung cancer patients participating in four separate protocols at three institutions in Europe and the United States. Seven patients were imaged using fluoroscopy, and 39 patients were imaged using 4DCT. The magnitude of respiratory tumor motion was measured. The required treatment field margins were calculated using a statistical recipe (van Herk M, et al. Int J Radiat Oncol Biol Phys 2000;474:1121–1135), with magnitudes of all uncertainties, except respiratory peak-to-peak displacement, the same for all patients, taken from literature. Required margins for respiratory motion management were calculated using the residual respiratory tumor motion for each patient for various motion management strategies. Margin reductions for respiration management were calculated using 4DCT, 4D-IG, and gated beam delivery. Results: The median tumor motion magnitude was 4.4 mm for the 46 patients (range 0–29.3 mm). This value corresponded to required treatment field margins of 13.7 to 36.3 mm (median 14.4 mm). The use of 4DCT, 4D-IG, and beam gating required margins that were reduced by 0 to 13.9 mm (median 0.5 mm), 3 to 5.2 mm (median 5.1 mm), and 0 to 7 mm (median 0.2 mm), respectively, to a total of 8.5 to 12.4 mm (median 8.6 mm). Conclusion: A respiratory management strategy for lung cancer radiotherapy including planning on 4DCT scans and daily image guidance provides a potential reduction of 37% to 47% in treatment field margins. The 4D image guidance strategy was the most effective strategy for >85% of the patients.

    The aim of the study was to evaluate the correlation between serum prostate specific antigen (PSA) level and bone scintigraphy in newly diagnosed untreated prostate cancer patients. The probability of a positive bone scan for metastases was analyzed for different threshold values of prostate specific antigen (PSA), acid phosphastase and alkaline phosphates. Fifty four newly diagnosed untreated prostate cancer patients (mean age, 67 years range, 41 to 94) were included in this study. In each case serum PSA, acid phosphatase and alkaline phosphatase measurements were performed followed by whole body Technetium-99m MDP bone scan. The positive predictive value of serum PSA level for bone metastases at the threshold of 10 ng/ml was 70% whereas the same threshold level of PSA gave a negative predictive value of 100%. We used receiver operating characteristics (ROC) analysis to examine the power of predictive value of each serum test, in predicting the results of the bone scan. We also applied regression analysis for the assessment of correlation between the levels of tumor markers and the extent of bone pathology. It was concluded that bone scintigraphy seems to be unnecessary in evaluation of newly diagnosed untreated prostate cancer in patients with no clinical signs of bone pathology and serum PSA levels of equal to or less than 10 ng/ml.

    The evaluation of tumor recurrence or metastasis in postgastrectomy cancer patients usually depends on a serum tumor marker test or radiologic study, but in both cases, accuracy is difficult to determine. The purpose of this study was to evaluate the relationship between abdominal CT and serum tumor markers. In 337cases involving 226 patients who had undergone curative surgery for gastric cancer, we compared serum tumor markers and CT for the evaluation of metastasis. Amoong these 337 cases, CEA level was measured in 317, CA 19-9 level in 166,and both of these in 146. The cutoff level for serum carcinoembryonic antigen (CEA) and CA19-9 were 10ng/ml and 33U/ml, respectively. CEA level was elevated in 59 of 317 cases(18.6%) and that of CA 19-9 in 58 of 166(34.9%). Slightly higher overall senstivity and specificity was observed for CEA than for CA19-9 (72.9% vs 67.2%, 83.3% vs 70.4%, respectively). Among the total of 337 cases, liver or lymph node metastases were detected in 91 cases (27.0%) on CT. Negative predictive value was significantly higher in CEA than in CA19-9 (93.1% vs 80%, respectively)(p<0.01), but positive predictive value was lower (50% vs 54.9%, respectively). On CT scan, there was a significant relationship between serum tumor marker level and hepatic and nodal metastasis ; specificity and positivity of serum tumor markers were both higher than senstivity and negativity. Follow-up CT less useful when tumor markers levels are not elevated, but when these are elevated in postgastrectomy cancer patients, meticulous radiologic evaluation is necessary for the early detection of residual or recurrent tumors

    Background: While breast magnetic resonance imaging (MRI) is a highly sensitive test for detecting breast carcinoma, its specificity is lower, and several methods have been described on how to optimize specificity. Purpose: To compare the specificity and sensitivity of the BI-RADS category with the Fischer score in breast MRI for diagnosing cancer in women previously treated for breast cancer. Material and Methods: Women referred for evaluation of possible local recurrence or new breast cancer underwent breast MRI examination. Morphologic and kinetic enhancement characteristics were evaluated. BI-RADS category and Fischer score were assigned for each enhancing lesion and compared using a chi-square test. Sensitivity, specificity, and positive predictive values for 27 morphologic and enhancement characteristics were calculated. Pathologic diagnosis was obtained in all patients with enhancing lesions who had ultrasound or mammographic correlation. In those without correlate, 6-, 12-, and 24-month follow-up breast MRIs were obtained. Interobserver kappa correlation was determined for each variable studied. Results: 34 benign and 32 malignant lesions were identified in 26 of 30 patients. BI-RADS category yielded a specificity of 77.1% and a sensitivity of 81.8%. Fischer score had a lower specificity and sensitivity (62.9% and 72.7%, respectively) (P 100% enhancement was more sensitive than BI-RADS for malignant lesions. Specificity was highest for rim enhancement (97.1%), but sensitivity was low (24.2%). Interobserver kappa correlation was good for all 27 characteristics ( = 0.84), and highest for BI-RADS assessment ( 0.91). Conclusion: BI-RADS category in breast MRI had the highest combination of specificity and sensitivity, and the highest interobserver correlation. Fischer score and other morphologic and enhancement features lack sensitivity or specificity and do not have high positive predictive values when analyzed as single independent variables

    Performance status measures are increasingly completed by patients in outpatient cancer settings, but are not well validated for this use. We assessed performance of a patient-reported functional status measure (PRFS, based on the Eastern Cooperative Oncology Group [ECOG]), compared with the physician-completed ECOG, in terms of agreement in ratings and prediction of survival. Patients and physicians independently completed five-point PRFS (lay version of ECOG) and ECOG measures on first consultation at an oncology palliative care clinic. We assessed agreement between PRFS and ECOG using weighted Kappa statistics, and used linear regression to determine factors associated with the difference between PRFS and ECOG ratings. We used the Kaplan-Meier method to estimate the patients' median survival, categorized by PRFS and ECOG, and assessed predictive accuracy of these measures using the C-statistic. For the 949 patients, there was moderate agreement between PRFS and ECOG (weighted Kappa 0.32; 95% CI: 0.28-0.36). On average, patients' ratings of performance status were worse by 0.31 points (95% CI: 0.25-0.37, P statistic was higher for the average of PRFS and ECOG scores (0.619) than when reported individually (0.596 and 0.604, respectively). Patients tend to rate their performance status worse than physicians, particularly if they are younger or have greater symptom burden. Prognostic ability of performance status could be improved by using the average of patients and physician scores. Copyright © 2018 American Academy of Hospice and Palliative Medicine.

    Full text: The objective of the current study was to determine whether pre- treatment serum prostate specific antigen (PSA) levels can identify a group with low probability of osseous metastases and safely eliminate the need for bone scan as a routine part of the staging evaluation in Bangladeshi patients with newly diagnosed prostate carcinoma. Also, to find out a cut off value for serum PSA level for predicting positive bone scan in newly diagnosed Bangladeshi prostate cancer patients and to assess the role of PSA level in hormonally treated cases. Prostate cancer most commonly metastasizes to the bone. Bone scintigraphy is one of the best methods in detecting bone metastases, assessing the progression of the disease and response to therapy. For more than 30 yrs it has been known that bone scintigraphy is more sensitive than radiographic, clinical evaluation or chemical markers such as alkaline phosphatase or acid phosphatase in detection of early osseous metastatic prostate cancer. The introduction of PSA has dramatically changed the management of prostate cancer. Serum PSA level has proven to be a useful serum marker for detection of metastatic prostate cancer and it provides the best overall correlation. It also has considerable impact on bone scanning. Of special significance is the fact that patients who have a low PSA level in previously untreated carcinoma of prostate are extremely unlikely to have positive findings on a bone scan for metastases. The picture is different in patients who has received and responded to hormonal therapy. Bone scintigraphy appears to be extremely useful in patients whose PSA level begins to rise after surgical procedure. Patients, who were on anti- androgen therapy, even though they had visible metastatic disease on bone scans, had normal level of PSA Patients and methods: A total of 390 cases were studied. Some (n=242) were newly diagnosed without having any specific treatment other than surgery. Others (n=148) were old cases

    Socioemotional selectivity theory proposes that, with more limited future time perspective (FTP), the meaning of individual life goals shifts from instrumental and long-term goals, such as autonomy, to emotionally meaningful and short-term life goals, especially concerning meaningful social relationships. Adverse side effects of cancer therapy may conflict with the realization of emotionally meaningful goals leading to nonadherence. In line with the theoretical assumptions, this study aimed to investigate (a) associations among disease symptoms, physical and cognitive limitations, and FTP and (b) among FTP, family network size, striving for autonomy, and treatment adherence. One hundred fifty-seven patients (43-90 years; 75% male) with head and/or neck cancer of a German University Medical Centre completed a questionnaire measuring FTP, age, disease symptoms, physical and cognitive functioning, family network size, and treatment adherence. Autonomy was assessed with a card sort task. A structural equation model yielded an acceptable fit χ 2 (28) = 44.41, P = .025, χ 2 /df = 1.59, root mean square error of approximation = 0.06 (90% CI = 0.02, 0.09), Tucker-Lewis Index = 0.92, and Comparative Fit Index = 0.96. An increased level of disease symptoms and physical and cognitive limitations was related to a shorter subjective FTP. Furthermore, individuals with a limited FTP reported a smaller family network, a lowered quest for autonomy, and lower treatment adherence. Hypotheses derived from socioemotional selectivity theory were supported by the data. Longitudinal investigations should follow to corroborate findings and to focus on underlying mechanisms as improving patients FTP may play a crucial role in future disease management programs.

    Lung cancer causes approximately one million deaths each year worldwide and protein p53 has been shown to be involved in the intricate processes regulating response to radiation and/or chemotherapeutic treatment. Consequently, since antibodies against p53 (anti-p53 antibodies) are associated with mutations within the p53 gene it seems likely that these antibodies could, hypothetically, be correlated with prognosis. Serum samples from patients with non-small cell lung cancer (NSCLC) admitted to the Department of Oncology, University Hospital, Uppsala, Sweden, during 1983–1996 were studied. Anti-p53 abs were measured using a sandwich ELISA (Dianova, Hamburg, Germany). The present study included 84 patients with stage IIIA-IV (advanced NSCLC). At least three serum samples from each patient were collected and altogether 529 serum samples were analysed for the presence of anti-p53 antibodies. The median value of anti-p53 antibodies was 0.06 (range 0 – 139.8). Seventeen percent of investigated NSCLC first serum samples (n = 84) expressed elevated levels of anti-p53 antibodies. Anti-p53 antibodies were not correlated to tumour volume or platelets. Survival analysis showed that anti-p53 antibodies were not associated with survival as revealed by univariate analysis (p = 0.29). However, patients with adenocarcinoma had a significantly poorer survival if they expressed anti-p53 antibodies (p = 0.01), whereas this was not found for patients with squamous cell carcinoma (p = 0.13). In patients where the blood samples were collected during radiation therapy, a statistically significant correlation towards poorer survival was found (p = 0.05) when elevated anti-p53 antibodies levels were present. No correlations to survival were found for serum samples collected prior to radiation therapy, during chemotherapy, or during follow-up. When anti-p53 antibodies were measured continuously, no increase in median anti-p53 values was observed the closer the individual patient come to

    Full text: The aim of this study was to compare findings at prostate MR to ultrasound findings and pathology specimens in patients who subsequently underwent radical prostatectomy. Of the 61 patients who underwent composite MR prostate imaging, 39 patients with elevated PSA levels and / or abnormal DRE findings were found to have cancer on transrectal ultrasound (TRUS) and biopsy (random sextant and targeted biopsies). MRI was performed using composite phased array and endorectal coils, using axial T1 and axial, coronal and sagittal T2 weighted images through the prostate, together with axial T1 weighted imaging through the pelvis. Fifteen patients out the 39 patients with documented cancer then underwent radical prostatectomy. The resected specimen pathology was then compared with the MR and TRUS findings. Comparison of findings at MRI with those at prostatectomy indicated approximately 82.4% correlation comparing right side and left side disease (TRUS = 80%). There was a 13.3% false positive for seminal vesicle involvement on MR (TRUS = 0%) and a 10% false negative rate on MR (TRUS 10%) compared with pathology specimens.There was a 26.7% false positive rate of extracapsular extension on MR (TRUS = 0%) and a 6.6% false negative rate on MR (TRUS = 20%) compared with the pathology specimens. Of the 39 patients who had undergone TRUS and biopsy, the disease appeared more extensive on MRI than suspected at ultrasound in 14/39 (35.9%). High resolution MR imaging of the prostate is an acceptable method for assessing the presence of prostate cancer. However, our early experience, in this small series, suggests that there is a high mis-staging of disease on MR as is the case with TRUS, although MR is better than TRUS. The results underscore the need for additional assessment with MR spectroscopy. Copyright (2002) Blackwell Science Pty Ltd

    The digital divide is a recognized public health problem caused by social determinants that exacerbate health disparities. Despite the "tectonic shift" in how most of the public obtains cancer information, underserved communities are at increased risk of being digitally marginalized. However, research that examines factors underlying eHealth information seeking in diverse health contexts is lacking. The aim of this paper is to explore preferences and use of eHealth cancer prevention information (CPI) among patients and caregivers attending a minority-serving oncology clinic using the comprehensive model of information seeking as a theoretical framework. Specifically, the study examined the role of social determinants and prevention orientation in differences in preference and use of the Internet for CPI seeking among this diverse sample. Survey methodology was used to identify social determinants and behavioral factors, including prevention orientation as correlates and predictors of respondents' (n=252) preferences and use of eHealth for CPI seeking. Less than half (112/252, 44.4%) of respondents said that if faced with the need to seek CPI, they would seek this information online. In the final logistic regression model, education, ethnicity, age, and prevention orientation made significant contributions to the model (Pdigitally underserved racial/ethnic group. Finally, additional factors underlying these differences should be explored to better tailor CPI eHealth information to diverse communities' information needs. ©Tamar Ginossar.

    Background and purpose: Prediction of late normal tissue reactions to radiotherapy would permit tailoring of dosage to each patient. Measurement of residual DNA double strand breaks using pulsed field gel electrophoresis (PFGE) shows promise in this field. The aim of this study was to test the predictive potential of PFGE in a group of retrospectively studied breast cancer patients.Materials and methods: Thirty nine patients, treated uniformly for breast cancer 9-15 years previously, with excision of the tumour and radiotherapy to the breast and drainage areas, were assessed clinically using the LENT SOMA scale, and a 5-mm punch biopsy taken from the buttock. Fibroblast cell strains were established and used to study residual DNA double strand breaks, using PFGE.Results: There were significant correlations between the DNA assay results and the fibrosis score (r s =0.46; P=0.003), the combined fibrosis and retraction score (r s =0.45, P=0.004) and the overall LENT score (r s =0.43; P=0.006). Using polychotomous logistic regression, the fibroblast DNA assay result was an independent prognostic factor for fibrosis severity.Conclusions: There is a relationship between residual radiation-induced DNA damage in fibroblasts and the severity of the late normal tissue damage seen in the patients from whom the cells were cultured.

  13. Expression of the Long Non-Coding RNA HOTAIR Correlates with Disease Progression in Bladder Cancer and Is Contained in Bladder Cancer Patient Urinary Exosomes.

    Directory of Open Access Journals (Sweden)

    Claudia Berrondo

    Full Text Available Exosomes are 30-150nM membrane-bound secreted vesicles that are readily isolated from biological fluids such as urine (UEs. Exosomes contain proteins, micro RNA (miRNA, messenger RNA (mRNA, and long non-coding RNA (lncRNA from their cells of origin. Although miRNA, protein and lncRNA have been isolated from serum as potential biomarkers for benign and malignant disease, it is unknown if lncRNAs in UEs from urothelial bladder cancer (UBC patients can serve as biomarkers. lncRNAs are > 200 nucleotide long transcripts that do not encode protein and play critical roles in tumor biology. As the number of recognized tumor-associated lncRNAs continues to increase, there is a parallel need to include lncRNAs into biomarker discovery and therapeutic target algorithms. The lncRNA HOX transcript antisense RNA (HOTAIR has been shown to facilitate tumor initiation and progression and is associated with poor prognosis in several cancers. The importance of HOTAIR in cancer biology has sparked interest in using HOTAIR as a biomarker and potential therapeutic target. Here we show HOTAIR and several tumor-associated lncRNAs are enriched in UEs from UBC patients with high-grade muscle-invasive disease (HGMI pT2-pT4. Knockdown of HOTAIR in UBC cell lines reduces in vitro migration and invasion. Importantly, loss of HOTAIR expression in UBC cell lines alters expression of epithelial-to-mesenchyme transition (EMT genes including SNAI1, TWIST1, ZEB1, ZO1, MMP1 LAMB3, and LAMC2. Finally, we used RNA-sequencing to identify four additional lncRNAs enriched in UBC patient UEs. These data, suggest that UE-derived lncRNA may potentially serve as biomarkers and therapeutic targets.

    CpG island methylation in the promoter regions of the DNA mismatch repair gene mutator L homologue 1 ( MLH1 ) and DNA repair gene O 6 -methylguanine-DNA methyltransferase ( MGMT ) genes has been shown to occur in the leukocytes of peripheral blood and colorectal tissue. However, it is unclear whether the methylation levels in the blood leukocytes and colorectal tissue are correlated. The present study analyzed and compared the levels of MGMT and MLH1 gene methylation in the leukocytes of peripheral blood and colorectal tissues obtained from patients with colorectal cancer (CRC). The methylation levels of MGMT and MLH1 were examined using methylation-sensitive high-resolution melting (MS-HRM) analysis. A total of 44 patients with CRC were selected based on the MLH1 and MGMT gene methylation levels in the leukocytes of the peripheral blood. Corresponding colorectal tumor and normal tissues were obtained from each patient and the DNA methylation levels were determined. The correlation coefficients were evaluated using Spearman's rank test. Agreement was determined by generalized κ-statistics. Spearman's rank correlation coefficients (r) for the methylation levels of the MGMT and MLH1 genes in the leukocytes of the peripheral blood and normal colorectal tissue were 0.475 and 0.362, respectively (P=0.001 and 0.016, respectively). The agreement of the MGMT and MLH1 gene methylation levels in the leukocytes of the peripheral blood and normal colorectal tissue were graded as fair and poor (κ=0.299 and 0.126, respectively). The methylation levels of MGMT and MLH1 were moderately and weakly correlated between the patient-matched leukocytes and the normal colorectal tissue, respectively. Blood-derived DNA methylation measurements may not always represent the levels of normal colorectal tissue methylation.

    Purpose: Capsular contracture (CC) is a serious complication in patients receiving implant-based reconstruction for breast cancer. The goal of this study was to identify image-based correlates of CC using MRI imaging in breast cancer patients who received both MRI and clinical evaluation following reconstructive surgery. Methods: We analyzed a retrospective dataset of 50 patients who had both a diagnostic MR and a plastic surgeon’s evaluations of CC score (Baker’s score) within a six month period following mastectomy and reconstructive surgery. T2w sagittal MRIs (TR/TE = 3500/102 ms, slice thickness = 4 mm) were used for morphological shape features (roundness, eccentricity, solidity, extent and ratio-length) and histogram features (median, skewness and kurtosis) of the implant and the pectoralis muscle overlying the implant. Implant and pectoralis muscles were segmented in 3D using Computation Environment for Radiological Research (CERR) and shape and histogram features were calculated as a function of Baker’s score. Results: Shape features such as roundness and eccentricity were statistically significant in differentiating grade 1 and grade 2 (p = 0.009; p = 0.06) as well as grade 1 and grade 3 CC (p = 0.001; p = 0.006). Solidity and extent were statistically significant in differentiating grade 1 and grade 3 CC (p = 0.04; p = 0.04). Ratio-length was statistically significant in differentiating all grades of CC except grade 2 and grade 3 that showed borderline significance (p = 0.06). The muscle thickness, median intensity and kurtosis were significant in differentiating between grade 1 and grade 3 (p = 0.02), grade 1 and grade 2 (p = 0.03) and grade 1 and grade 3 (p = 0.01) respectively. Conclusion: Morphological shape features described on MR images were associated with the severity of CC. MRI may be important in objectively evaluating outcomes in breast cancer patients who undergo implant reconstruction.

    Full Text Available We studied the putative significance of angiotensin I-converting enzyme (ACE in colorectal cancer (CRC biology. Local expression of ACE was investigated by quantitative reverse transcription- polymerase chain reaction and by immunohistochemistry in CRCs and adenomas. ACE insertion (I/deletion (D polymorphism was studied in 141 CRC patients and 189 controls. ACE mRNA was upregulated in CRCs compared to corresponding nonlesional tissues (2.5-fold; P = .009. ACE protein was more commonly expressed in adenomas [17 (81 %] and cancer epithelial cells [22 (100%] than in corresponding non-neoplastic crypt and surface epithelium [2 (10% and 2 (9%, respectively]. Thirty-seven CRC patients (26% carried II genotype, 69 (49% carried ID genotype, 35 (25% carried DD genotype. The distribution of the genotypes did not differ from that of controls. Female CRC patients more commonly carried the ID genotype and less frequently the II and DD genotypes compared with male patients (P = .033. Men heterozygous or homozygous for the D-allele had larger tumors compared to carriers of the II genotype (P < .01. Women homozygous for the D-allele lived longer than carriers of the ID and II genotypes. Our study shows that ACE is differentially expressed in CRCs and that gene polymorphism is associated with gender-specific differences in primary tumor size and patient survival.

    The aim of this study was to analyse whether the level of tissue inhibitor of metalloproteinases (TIMP) 1 is associated with the tumour response and survival to preoperative radiochemotherapy in rectal cancer patients. Ninety-two patients with histologically confirmed non-metastatic rectal cancer of clinical stage I– III were treated with preoperative radiochemotherapy, surgery and postoperative chemotherapy. Plasma TIMP-1 concentrations were measured prior to the start of the treatment with an enzyme-linked immunosorbent assay (ELISA). Median follow-up time was 68 months (range: 3–93 months) while in survivors it was 80 months (range: 68–93 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates for all patients were 80.2%, 56.4%, 63.7% and 52.2%, respectively. The median TIMP-1 level was 185 ng/mL (range: 22–523 ng/mL) and the mean level (±standard deviation) was 192 (±87) ng/mL. Serum TIMP-1 levels were found to be significantly increased in patients with preoperative CRP>12 mg/L and in those who died from rectal cancer or had cT4 tumours. No correlation was established for age, gender, carcinoembriogenic antigene (CEA) level, platelets count, histopathological grade, response to preoperative therapy, resectability and disease reappearance. On univariate analysis, various parameters favourably influenced one or more survival endpoints: TIMP-1 <170 ng/mL, CRP <12 mg/L, platelets count <290 10E9/L, CEA <3.4mg/L, age <69 years, male gender, early stage disease (cN0 and/or cT2–3), radical surgery (R0) and response to preoperative radiochemotherapy. In multivariate model, LRC was favourably influenced by N-downstage, DFS by lower CRP and N-downstage, DSS by lower CRP and N-downstage and OS by lower TIMP-1 level, lower CRP and N-downstage. Although we did not find any association between pretreatment serum TIMP-1 levels and primary tumour response to preoperative

    In metastatic testicular cancer patients treated with bleomycin, etoposide, and cisplatin (BEP) chemotherapy, bleomycin-induced pneumonitis is a well-known and potentially fatal side effect. We sought to determine the prevalence of lesions as signs of bleomycin-induced pulmonary changes on restaging computed tomography (CT) scans after treatment and to ascertain whether fibrosis markers were predictive of these changes. This prospective nonrandomized cohort study included metastatic testicular cancer patients, 18-50 years of age, treated with BEP chemotherapy. Restaging CT scans were examined for lesions as signs of bleomycin-induced pulmonary changes by two independent radiologists and graded as minor, moderate, or severe. Plasma samples were collected before, during, and after treatment and were quantified for transforming growth factor-β1 (TGF-β1), growth differentiation factor-15 (GDF-15), and high-sensitivity C-reactive protein (hs-CRP). In total, 66 patients were included: forty-five (68%) showed signs of bleomycin-induced pulmonary changes on the restaging CT scan, 37 of which were classified as minor and 8 as moderate. No differences in TGF-β1, GDF-15, or hs-CRP plasma levels were found between these groups. Bleomycin-induced pulmonary changes are common on restaging CT scans after BEP chemotherapy for metastatic testicular cancer. Changes in TGF-β1, GDF-15, and hs-CRP plasma levels do not differ between patients with and without radiological lesions as signs of bleomycin-induced pulmonary changes and are therefore not helpful as predictive biomarkers. Bleomycin-induced pneumonitis (BIP) is a well-known and potentially fatal side effect in metastatic testicular cancer patients treated with bleomycin, etoposide, and cisplatin chemotherapy. Currently, the decision to discontinue bleomycin administration is made during treatment and is based on clinical signs. An upfront or early marker or biomarker that identifies patients likely to develop BIP would be

    Purpose: The sentinel lymph node biopsy (SLNB) concept using the cutaneous (subdermal) peri-areolar approach is rapidly emerging as the technique for axillary staging in breast cancer. The procedure indicates whether axillary lymph node dissection (ALND) is necessary, therefore drastically minimising the invasiveness of surgical treatment. The SLNB concept is based on evidence suggesting that malignant disease primarily affects the sentinel node (SN) before being disseminated into the axillary lymph nodes (ALNs). Objective: This study was to define the role of lymphoscintigraphy in the visualisation of SNs during SLNB and to establish the correlation between the number of SNs identified on lymphoscintigraphy to the number of surgically identified SNs. Method: The study was a non-experimental, correlation study utilising quantitative data. Lymphoscintigraphy reports and histology results of 55 female breast cancer patients who underwent SLNB with partial or total back-up ALND, were retrospectively evaluated. Results: A maximum of 2 and a minimum of 0 sentinel nodes were visualised on lymphoscintigraphy in 52 out of 55 patients. Successful lymphoscintigraphy was highly predictive (p ≤ 0.001) of a successful SLNB as all 52 patients (94.5%) proceeded to have successful SN/s identification. There was a significant association (p ≤ 0.05) between the number of SN/s visualised on lymphoscintigraphy and the number of SN/s identified during SLNB. Lymphoscintigraphy accurately predicted the number of surgically identified SNs in 50.91% of cases (28/55). Conclusion: Considering that successful imaging effectively assures SN identification, the routine use of lymphoscintigraphy using the subdermal peri-areolar approach is fundamental in the reliable performance of SLNB.

    Purpose: To evaluate the value of T2w endorectal MRI (eMRI) for correct detection of tumor foci within the prostate regarding tumor size. Materials and Methods: 70 patients with histologically proven prostate cancer were examined with T2w eMRI before radical prostatectomy at a 1.5 T scanner. For evaluation of eMRI, two radiologists evaluated each tumor focus within the gland. After radical prostatectomy, the prostates were prepared as whole-mount sections, according to transversal T2w eMRI. For each slice, tumor surroundings were marked and compared with eMRI. Based on whole-mount section, 315 slices were evaluated and 533 tumor lesions were documented. Results: Based on the T2w eMRI, 213 tumor lesions were described. In 137/213, histology could prove these lesions. EMRI was able to visualize 0/56 lesions with a maximum size of 2 cm 50/56 (89%). False positive eMRI findings were: 2 cm n = 2. Conclusion: T2w eMRI cannot exclude prostate cancer with lesions smaller 10 mm and 0.4 cm 3 respectively. The detection rate for lesions more than 20 mm (1.6 cm 3 ) is to be considered as high.

    Purpose: The ASTRO Consensus Panel on PSA After Radiation Therapy recently recommended a definition of biochemical failure (BF) following treatment of prostate cancer with radiation therapy. We reviewed our institution's experience treating patients with external beam irradiation (RT) to determine if the Consensus Panel definition correlates with clinical distant metastases free survival (DMFS), disease free survival (DFS), cause specific survival (CSS), and local control (LC) rates for a large group of patients from the PSA era. Methods And Materials: Between 1/1/87 and 12/31/92, 653 patients with clinically localized prostate cancer received external beam irradiation (RT) using localized prostate fields at William Beaumont Hospital. Of these patients, 568 had a minimum follow-up of 2 years and constitute the study population. The median pre-treatment PSA and Gleason score was 11 ng/ml and 6, respectively. The median dose to the prostate using megavoltage RT was 66.6 Gy (range: 60-70.4 Gy) using a four field or arc technique. No patient received hormonal therapy either prior to, during, or after radiotherapy unless local or distant failure was documented. Pre-treatment and post-treatment serum PSA levels were recorded. Biochemical failure was defined as three consecutive increases in post-treatment PSA after achieving a nadir. Biochemical failure was recorded as the time midway between the nadir and first increase in PSA. Five year actuarial rates of DMFS, DFS, CSS, and LC were calculated for patients who were biochemically controlled (BC) versus those who failed biochemically. Results: Median follow-up was 56 months (range: 24-118 months). The overall 5 year actuarial rates of DMFS, DFS, CSS, and LC were significantly better in patients who were biochemically controlled versus those who were not (p< 0.001). The median time to DM within the BF group was 21 months (range: 2-112 months). When stratifying by pre-treatment PSA, Gleason score, and T stage, these

    In patients with cancer receiving potentially cardio-toxic chemotherapy, measurements of left ventricular (LV) circumferential or longitudinal strain are often used clinically to identify myocardial dysfunction. Using a new software algorithm, we sought to determine in individuals receiving treatment for cancer the association between automated assessments of LV mean mid-wall circumferential strain and conventional measures of LV ejection fraction (EF) both obtained from cardiovascular magnetic resonance (CMR) cine balanced steady-state free-precession (bSSFP) white-blood acquisitions. Before and 3 months after initiating treatment with potentially cardio-toxic chemotherapy, 72 individuals (aged 54 ± 14 years with breast cancer [39%], lymphoma [49%], or sarcoma [12%]) underwent serial CMR cine bSSFP assessments of LV volumes and EF, and mean mid-wall circumferential strain determined from these same cine images as well as from additional tagged CMR images. On the cine images, assessments of strain were obtained using the newly developed deformation-based segmentation algorithm. Assessments of LV volumes/EF from the cine images and strain from tagged CMR were accomplished using commercially available software. All measures were analyzed in a blinded fashion independent of one another. Acceptable measures for the automated assessments of mean mid-wall circumferential strain from the cine images were obtained in 142 of 144 visits (98.6%) with an overall analysis time averaging 6:47 ± 1:06 min. The results from these automated measures averaged -18.8 ± 2.9 at baseline and -17.6 ± 3.1 at 3 months (p = 0.001). Left ventricular EF declined slightly from 65 ± 7% at baseline to 62 ± 7% at 3 months (p = 0.0002). The correlation between strain from cine imaging and LVEF was r = -0.61 (p cine and tagged derived assessments of strain was r = 0.23; p = 0.01. Automated measures of LV mean mid-wall circumferential strain can be obtained in 6

    In patients with metastatic colorectal cancer (mCRC), radiological imaging represents the current standard to evaluate the efficacy of chemotherapy. However, with growing knowledge about tumor biology, other diagnostic tools become of interest which can supplement radiology. The aim of the present study was to examine the correlation of tumor and serum markers with radiological imaging in patients with mCRC receiving first-line therapy. Patients were included if tumor (carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9)) and serum marker (lactatdehydrogenase (LDH), γ-glutamyltransferase (γGT), alkaline phosphatase (AP), C-reactive protein (CRP), leucocyte count (WBC), hemoglobin (Hb)) levels were available at baseline and at least two times during treatment. The decline and increase of tumor and serum markers over time were approximated for each patient by estimating slopes depending on the radiological assessment. A linear mixed effects multiple regression model for each subject was used to evaluate the intra-class correlation of these slopes modeling tumor and serum marker changes with radiological imaging. Data of 124 patients (41 female, 83 male; median age 62.9 years, range 27-85) who received first-line chemotherapy for mCRC from 11/2007 to 04/2010 were analyzed retrospectively. CEA level slopes (n = 49; slopes = 102) differed between radiologically determined progressive disease (PD) and partial response (PR) (p = 0.005) and between PD and stable disease (SD) (p = 0.042). CA 19-9 level slopes (n = 57; slopes = 127) also showed a significant difference between PD and PR (p = 0.002) and PD and SD (p = 0.058). Furthermore, CRP slopes (n = 62; slopes = 134) differed significantly between PD and PR (p = 0.009). For LDH, ALP, γGT, Hb, and WBC, no correlations were observed. The results indicate the correlation of the tumor markers CEA, CA 19-9, and the serum marker CRP with radiological imaging in

    Full Text Available Mast cells proteases, tryptase and chymase are directly involved in the growth and progression of solid tumors due to their important role in tumor angiogenesis. We examined the density of tryptase positive mast cells and the mean density of new blood vessels in gastric malignant tumors of patients with and without Helicobacter pylori infection, using immunohistochemical staining for tryptase (for mast cells and CD 105 (for new vessels. Tryptase and CD 105 expression was detected in gastrectomy specimens. In this study, mast cell density correlates with angiogenesis and the growth and progression of gastric cancer. It also shows that the participation of Helicobacter pylori infection in the growth and progress of gastric neoplasia is due to an increase of peritumoral angiogenesis, with subsequent local and distant tumor spread and perivascular growth, but without perineural and nodal involvement.

    Introduction: The utilization of the post-traumatic stress disorder (PTSD) diagnostic spectrum is currently being debated to categorize psychological adjustment in cancer patients. The aims of this study were to: (1) evaluate the presence of cancer-related traumatic dissociative symptomatology in a sample of cancer patients; (2) examine the correlation of cancer-related dissociation and sociodemographic and medical variables, anxiety, depression, and post-traumatic stress symptomatology; (3) investigate the predictors of cancer-related dissociation. Methods: Ninety-two mixed cancer patients (mean age: 58.94, ds = 10.13) recruited from two hospitals in northern Italy were administered a questionnaire on sociodemographic and medical characteristics, the Karnofsky Scale to measure the level of patient activity and medical care requirements, the Hospital Anxiety and Depression Scale (HADS) to evaluate the presence of anxiety and depression, the Impact of Event Scale Revised (IES-R) to assess the severity of intrusion, avoidance, and hypervigilance, and the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) to quantify the traumatic dissociative symptomatology. Results: 31.5% of participants report a PDEQ score above the cutoff. The results indicated that dissociative symptomatology was positively correlated with HADS scores (HADS-Anxiety: r = 0.476, p dissociative symptomatology. The results converged on a three predictor model revealing that IES-R-Intrusion, IES-R-Avoidance, and IES-R-Hyperarousal accounted for 53.9% of the explained variance. Conclusion: These findings allow us to hypothesize a specific psychological reaction which may be ascribed to the traumatic spectrum within the context of cancer, emphasizing the close relationship between the origin of dissociative constituents which, according to the scientific literature, compose the traumatic experience. Our results have implications for understanding dissociative symptomatology in a cancer

    Full Text Available Background and objective The main manifestations of radiation pneumonitis are injury of alveolar epithelial and endothelial cells, abnormal expression of cytokines, abnormal proliferation of fibroblasts and synthesis of fibrous matrix. The occurrence of radiation pneumonitis is associated with multiplecytokine level abnormality. These cytokines can also be used as bio-markers to predict the occurrence of radiation pneumonitis. This study was to evaluate the correlation between the change of apurinic/apyrimidinic endonuclease 1/redox factor-1 (Ape1/Ref-1, intercellular adhesion molecules 1 (ICAM-1 and interleukin-17A (IL-17A before and after radiotherapy and radiation pneumonitis for local advanced non-small cell lung cancer (NSCLC patients with concurrent chemoradiotherapy. Methods NSCLC patients (68 cases were treated with concurrent radiotherapy and chemotherapy, every patient’s normal tissue were controlled with a same radation dose. 68 local advanced NSCLC patients with concurrent chemoradiotherapy were detected the levels of Ape1/Ref-1, ICAM-1 and IL-17A in serum by ELISA before radiotherapy and in the 14th week after radiotherapy. Acute and advanced radiation pulmonary injury was graded according to Radiation Therapy Oncology Group/European Organization For Research and Treatment (RTOG/EORTC diagnostic and grading criteria. Grade 2 or more radiation pneumonitis was taken as the main end point. Results Eighteen cases out of 68 developed radiation pneumonitis, 50 of 68 cases have no radiation pneumonia development. There was no significant change of Ape1/Ref-1 levels before and after radiotherapy in radiation pneumonitis group (P>0.05. There was no significant change of Ape1/Ref-1 concentration in serum after radiotherapy between radiation pneumonitis group and non-radiation pneumonitis group (P>0.05. Compared with before radiotherapy, upregulation degree of ICAM-1 levels in radiation pneumonitis group was significantly higher than that in

    Full Text Available It is not enough to consider treatment and care depression in the oncology that is the most common psychiatric illness in cancer patient affects of cancer treatment and the patient`s quality of life negatively, which is determined through researches in the field. With development of psycho-oncology it has been demonstrated to establish an important link between the cancer patient`s treatment as well as psycho-social support for the patient and psychiatric treatment and care for the if it is needed. With this connection between them it has been proposed to use of bio-psycho-social-model in cancer patient to improve their care. To achieve this goal, it is expected from medical personnel to realize patients psychosocial need und if he/she has a psychiatric disorders or syndromes. For the medical personnel that work in oncology services, it is inevitable to organize in order to raise the awareness of depression in the cancer patients. In the present study, it is focused on raising the awareness of depression in cancer patient for the medical personnel.

    Different ethnicities have different distribution of Duffy blood group (DBG) phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype), led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022) suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. The incidence of breast cancer was significantly different between FYa + FYb + (29.8%), FYa + FYb- (33.2%), FYa-FYb + (45.6%) and FYa-FYb- (59.1%; P = 0.001). Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%), FYa + FYb- (36.9%), FYa-FYb + (41.0%) and FYa-FYb- (50.0%, (P = 0.005). There was a statistical significance (p = 0.022) of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05), histological cancer type (Fisher's exact test, p > 0.05) or histological grade (Fisher's exact test, p > 0.05) between every each DBGP group. DBGP is correlated with breast cancer incidence and axillary lymph node metastasis and overall survival. Further investigations are required to determine the underlying mechanism of Duffy blood group phenotype on breast cancer risk

    Full Text Available Overexpression of ABC drug transporters can cause multidrug resistance (MDR in cancer cells, which is a major obstacle in the success of cancer chemotherapy. Our study revealed a correlation between the expression of invasive breast cancer resistance-associated proteins, such as P-glycoprotein (ABCB1, MRP2 (ABCC2, BCRP (ABCG2 in tumor cells and pathologic response to neoadjuvant chemotherapy. The response to neoadjuvant chemotherapy was shown to be associated with a lack of BCRP expression in tumor cells. The pathologic tumor response was correlated with the presence of positive MRP2 expression and the expression level of P-glycoprotein in cells of invasive breast cancer

    Purpose: We reviewed our institution's experience treating patients with external beam irradiation (RT) to determine if the ASTRO Consensus Panel definition of biochemical failure (BF) following radiation therapy correlates with clinical distant metastases free survival (DMFS), disease-free survival (DFS), cause-specific survival (CSS), and local control (LC). Methods and Materials: Between 1/1/87 and 12/31/92, 568 patients with clinically localized prostate cancer received external beam irradiation (RT) using localized prostate fields at William Beaumont Hospital (median total dose 66.6 Gy; range: 60-70.4 Gy). Biochemical failure was defined as three consecutive increases in post-treatment prostate specific antigen (PSA) after achieving a nadir. Biochemical failure was recorded as the time midway between the nadir and the first rising PSA. Five-year actuarial rates of clinical DMFS, DFS, CSS, and LC were calculated for patients who were biochemically controlled (BC) versus those who failed biochemically. Median follow-up was 56 months (range: 24-118 months). Results: Five-year actuarial rates of DMFS, DFS, CSS, and LC were significantly greater in patients who were biochemically controlled versus those who were not (p < 0.001). In patients who were BC, the 5-year actuarial rates of DMFS, DFS, CSS, and LC were 99%, 99%, 98%, and 99% respectively. For patients who failed biochemically, the 5-year actuarial rates of DMFS, DFS, CSS, and LC were 74%, 64%, 89%, and 86% respectively. When stratifying by pretreatment PSA, Gleason score, and T stage these differences remained significant for DMFS, DFS, and CSS. The Cox proportional hazards model demonstrated that BC was the single most important predictor of clinical outcome for DMFS, DFS, CSS, and LC. Pretreatment PSA and Gleason score were also independent predictors of outcome for DMFS and DFS. Conclusions: The ASTRO Consensus Panel definition of BF following radiation therapy correlates well with clinical DMFS, DFS

    Full Text Available Abstract Background The prognosis of gastric cancer patients is difficult to predict because of defects in establishing the surgical-pathological features. Cancer-associated fibroblasts (CAFs have been found to play prominent role in promoting tumor growth, invasion and metastasis. Thus raises the hypothesis that the extent of CAFs prevalence may help to establish the prognosis of gastric cancer patients. Methods Immunochemistry and realtime-PCR experiments were carried out to compare the expression of proteins which are specific markers of CAFs or secreted by CAFs in the tumor and normal tissue specimens. The extent of CAFs' prevalence was graded according to immunochemical staining, and correlation was further analyzed between CAFs' prevalence and other tumor characteristics which may influence the prognosis of gastric cancer patients. Results Nearly 80 percent of normal gastric tissues were negative or weak positive for CAFs staining, while more than 60 percent of gastric cancer tissues were moderate or strong positive for CAFs staining. Realtime-PCR results also showed significant elevated expression of FAP, SDF-1 and TGF-β1 in gastric cancer tissues compared to normal gastric tissues. Further analysis showed that CAFs' prevalence was correlated with tumor size, depth of the tumor, lymph node metastasis, liver metastasis or peritoneum metastasis. Conclusions Reactive cancer associated fibroblasts (CAFs were frequently accumulated in gastric cancer tissues, and the prevalence of CAFs was correlated with tumor size, depth of the tumor and tumor metastasis, thus give some supports for establishing the prognosis of the gastric cancer patients.

    With the wide application of targeted drug therapies, the relevance of prognostic and predictive markers in patient selection has become increasingly important. Bevacizumab is commonly used in combination with chemotherapy in the treatment of metastatic colorectal cancer. However, there are currently no predictive or prognostic biomarkers for bevacizumab. Several clinical studies have evaluated bevacizumab-induced hypertension in patients with metastatic colorectal cancer. This meta-analysis was performed to better determine the association of bevacizumab-induced hypertension with outcome in patients with metastatic colorectal cancer, and to assess whether bevacizumab-induced hypertension can be used as a prognostic factor in these patients. We performed a systematic review and meta-analysis on seven published studies to investigate the relationship between hypertension and outcome of patients with metastatic colorectal cancer treated with bevacizumab. Our primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS) and overall response rate (ORR). Hazard ratios (HRs) for PFS and OS were extracted from each trial, and the log of the relative risk ratio (RR) was estimated for ORR. The occurrence of bevacizumab-induced hypertension in patients was highly associated with improvements in PFS (HR = 0.57, 95% CI: 0.46-0.72; P hypertension. Bevacizumab-induced hypertension may represent a prognostic factor in patients with metastatic colorectal cancer.

    To describe the unique MRI findings of superior cervical ganglia (SCG) that may help differentiate them from retropharyngeal lymph nodes (RPLNs). A retrospective review of post-treatment NPC patients from 1999 to 2012 identified three patients previously irradiated for NPC that were suspected of having recurrent nodal disease in retropharyngeal lymph nodes during surveillance MRI. Subsequent surgical exploration revealed enlarged SCG only; no retropharyngeal nodal disease was found. A cadaveric head specimen was also imaged with a 3T MRI before and after dissection. In addition, SCG were also harvested from three cadaveric specimens and subjected to histologic analysis. The SCG were found at the level of the C2 vertebral body, medial to the ICA. They were ovoid on axial images and fusiform and elongated with tapered margins in the coronal plane. T2-weighted (T2W) signal was hyperintense. No central elevated T1-weighted (T1W) signal was seen within the ganglia in non-fat-saturated sequences to suggest the presence of a fatty hilum. Enhancement after gadolinium was present. A central ''black dot'' was seen on axial T2W and post-contrast images in two of the three SCG demonstrated. Histology showed the central black line was comprised of venules and interlacing neurites within the central portion of the ganglion. The SCG can be mistaken for enlarged RPLNs in post-treatment NPC patients. However, there are features which can help differentiate them from RPLNs, preventing unnecessary therapy. These imaging findings have not been previously described. (orig.)

    Full Text Available PURPOSE: Epithelial-Mesenchymal Transition (EMT features appear to be key events in development and progression of breast cancer. Epigenetic modifications contribute to the establishment and maintenance of cancer subclasses, as well as to the EMT process. Whether histone variants contribute to these transformations is not known. We investigated the relative expression levels of histone macroH2A1 splice variants and correlated it with breast cancer status/prognosis/types. METHODS: To detect differential expression of macroH2A1 variant mRNAs in breast cancer cells and tumor samples, we used the following databases: GEO, EMBL-EBI and publisher databases (may-august 2012. We extracted macroH2A1.1/macroH2A1 mRNA ratios and performed correlation studies on intrinsic molecular subclasses of breast cancer and on molecular characteristics of EMT. Associations between molecular and survival data were determined. RESULTS: We found increased macroH2A1.1/macroH2A1 mRNA ratios to be associated with the claudin-low intrinsic subtype in breast cancer cell lines. At the molecular level this association translates into a positive correlation between macroH2A1 ratios and molecular characteristics of the EMT process. Moreover, untreated Triple Negative Breast Cancers presenting a high macroH2A1.1 mRNA ratio exhibit a poor outcome. CONCLUSION: These results provide first evidence that macroH2A1.1 could be exploited as an actor in the maintenance of a transient cellular state in EMT progress towards metastatic development of breast tumors.

    Involvement of matrix metalloproteinases (MMPs) in the pathogenesis of urothelial carcinoma elects them to be sensitive marker for clinical and prognostic implications. MMPs regulate tumor growth and invasion by inducing epithelial-to-mesenchymal transition (EMT) which is characterized by the complex reprogramming of epithelial cells and ultimately bring about major changes in the structural organization of bladder urothelium. The present study has been undertaken to evaluate the clinical relevance of MMPs in two distinct types of bladder cancer disease. Expression analysis of MMPs namely MMP-2, MMP-7, MMP-9 and EMT markers including epithelial marker, E-cadherin; mesenchymal markers, N-cadherin and Vimentin; and EMT-activating transcriptional factors (EMT-ATFs), Snail, Slug, Twist and Zeb was done in 64 cases of bladder tumor tissues [{Non-muscle invasive bladder cancer (NMIBC): 35 cases} and {Muscle invasive bladder cancer (MIBC): 29 cases}] by real-time quantitative polymerase chain reaction (RT-qPCR). Immunohistochemistry (IHC) staining was done in matched bladder tumor tissues to evaluate the protein expression and localization of E-cadherin, N-cadherin, Vimentin, Snail, and Slug. Our data showed overexpression of MMP-2, MMP-7 and MMP-9 at transcriptome level in 32.8%, 25% and 37.5% bladder tumor cases respectively. These tumor tissues were examined for higher expression of mesenchymal markers (N-cadherin and Vimentin) at mRNA and protein level and exhibited statistical association with tumor stage and tumor grade (p = 0.02, p = 0.04, Mann-Whitney test). Significant statistical correlation in tumor tissues with overexpressed MMPs has also been observed between gain of transcriptional factors and weak expression of E-cadherin with tumor stage, grade, gender, presence of hematuria and smoking history of the patients.

    Purpose: To test the hypothesis that radiation dose to 18 F-fluorodeoxyglucose positron emission tomography ( 18 F-FDG-PET)-defined active bone marrow (BM ACT ) subregions is correlated with hematologic toxicity in cervical cancer patients treated with chemoradiotherapy. Methods and Materials: The conditions of 26 women with cervical cancer who underwent 18 F-FDG-PET before treatment with concurrent cisplatin and intensity-modulated radiation therapy were analyzed. BM ACT was defined as the subregion of total bone marrow (BM TOT ) with a standardized uptake value (SUV) equal to or above the mean for that individual. Inactive bone marrow (BM INACT ) was defined as BM TOT − BM ACT . Generalized linear modeling was used to test the correlation between BM ACT and BM INACT dose–volume metrics and hematologic nadirs, particularly white blood cell count (WBC) and absolute neutrophil count (ANC). Results: Increased BM ACT mean dose was significantly associated with decreased log(WBC) nadir (β = −0.04; 95% CI, −0.07to −0.01; p = 0.009), decreased log(ANC) nadir (β = −0.05; 95% CI, −0.08 to −0.02; p = 0.006), decreased hemoglobin nadir (β = −0.16; 95% CI, −0.27 to −0.05; p = 0.010), and decreased platelet nadir (β = −6.16; 95% CI, −9.37 to −2.96; p INACT mean dose and log(WBC) nadir (β = −0.01; 95% CI, −0.06 to 0.05; p = 0.84), log(ANC) nadir (β = −0.03; 95% CI, −0.10 to 0.04; p = 0.40), hemoglobin nadir (β = −0.09; 95% CI, −0.31 to 0.14; p = 0.452), or platelet nadir (β = −3.47; 95% CI, −10.44 to 3.50; p = 0.339). Conclusions: Irradiation of BM subregions with higher 18 F-FDG-PET activity was associated with hematologic toxicity, supporting the hypothesis that reducing dose to BM ACT subregions could mitigate hematologic toxicity. Future investigation should seek to confirm these findings and to identify optimal SUV thresholds to define BM ACT .

    Tumor expression of estrogen receptor (ER) is an important marker of prognosis, and is predictive of response to endocrine therapy in breast cancer. Several studies have observed that epigenetic events, such methylation of cytosines and deacetylation of histones, are involved in the complex mechanisms that regulate promoter transcription. However, the exact interplay of these factors in transcription activity is not well understood. In this study, we explored the relationship between ER expression status in tumor tissue samples and the methylation of the 5′ CpG promoter region of the estrogen receptor gene (ESR1) isolated from free circulating DNA (fcDNA) in plasma samples from breast cancer patients. Patients (n = 110) with non-metastatic breast cancer had analyses performed of ER expression (luminal phenotype in tumor tissue, by immunohistochemistry method), and the ESR1-DNA methylation status (fcDNA in plasma, by quantitative methylation specific PCR technique). Our results showed a significant association between presence of methylated ESR1 in patients with breast cancer and ER negative status in the tumor tissue (p = 0.0179). There was a trend towards a higher probability of ESR1-methylation in those phenotypes with poor prognosis i.e. 80% of triple negative patients, 60% of HER2 patients, compared to 28% and 5.9% of patients with better prognosis such as luminal A and luminal B, respectively. Silencing, by methylation, of the promoter region of the ESR1 affects the expression of the estrogen receptor protein in tumors of breast cancer patients; high methylation of ESR1-DNA is associated with estrogen receptor negative status which, in turn, may be implicated in the patient’s resistance to hormonal treatment in breast cancer. As such, epigenetic markers in plasma may be of interest as new targets for anticancer therapy, especially with respect to endocrine treatment

    The goal of this study was to assess the correlation between estrogen receptor (ER) status and histopathology findings, likewise to assess some selected prognostic factors in patients with breast cancer. The study was carried out on 126 patients with breast cancer. ER concentration was estimated by the standard biochemical assay (DCC-dextran-coated charcoal assay). The correlation between established risk factors like: lymph node status; age menopausal status and ER status were analysed.The ER yielded in 61% positive results. The mean value of ER in invasive ductal carcinoma was 43.9 fmol/mg protein and the mean value of ER in invasive lobular carcinoma 51.4 fmol/mg protein. The significant statistics negative correlation between ER status of pre-menopausal patients with ductal breast carcinoma and regional lymph nodes involvement was found. There was no difference between ER status and histological type of the cancer. No correlation was found between ER status and age of patients. (author) 32 refs, 2 figs, 2 tabs

    Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

    Purpose: To correlate dose distributions computed using six algorithms for recurrent early stage non-small cell lung cancer (NSCLC) patients treated with stereotactic body radiotherapy (SBRT), with outcome (local failure). Methods: Of 270 NSCLC patients treated with 12Gyx4, 20 were found to have local recurrence prior to the 2-year time point. These patients were originally planned with 1-D pencil beam (1-D PB) algorithm. 4D imaging was performed to manage tumor motion. Regions of local failures were determined from follow-up PET-CT scans. Follow-up CT images were rigidly fused to the planning CT (pCT), and recurrent tumor volumes (Vrecur) were mapped to the pCT. Dose was recomputed, retrospectively, using five algorithms: 3-D PB, collapsed cone convolution (CCC), anisotropic analytical algorithm (AAA), AcurosXB, and Monte Carlo (MC). Tumor control probability (TCP) was computed using the Marsden model (1,2). Patterns of failure were classified as central, in-field, marginal, and distant for Vrecur ≥95% of prescribed dose, 95–80%, 80–20%, and ≤20%, respectively (3). Results: Average PTV D95 (dose covering 95% of the PTV) for 3-D PB, CCC, AAA, AcurosXB, and MC relative to 1-D PB were 95.3±2.1%, 84.1±7.5%, 84.9±5.7%, 86.3±6.0%, and 85.1±7.0%, respectively. TCP values for 1-D PB, 3-D PB, CCC, AAA, AcurosXB, and MC were 98.5±1.2%, 95.7±3.0, 79.6±16.1%, 79.7±16.5%, 81.1±17.5%, and 78.1±20%, respectively. Patterns of local failures were similar for 1-D and 3D PB plans, which predicted that the majority of failures occur in centraldistal regions, with only ∼15% occurring distantly. However, with convolution/superposition and MC type algorithms, the majority of failures (65%) were predicted to be distant, consistent with the literature. Conclusion: Based on MC and convolution/superposition type algorithms, average PTV D95 and TCP were ∼15% lower than the planned 1-D PB dose calculation. Patterns of failure results suggest that MC and convolution

    Pepsinogen I and Pepsinogen II (PG I and PG II) were purified from human gastric mucosa using DE-52 anion exchange chromatography, Gel filtration HPLC and Q-2 anion exchange fast pressure chromatography. The antiserums against at both PG I and PG II were established respectively by preparing 125 I-PG I and 125 I-PG II using the chloramine-T method. Serum Pepsinogen I and II levels were measured by RIA in 190 healthy controls and other gastric diseases. The results were analyzed by statistics method. Compared with healthy controls, the serum PG I levels of duodenal ulcer patients and gastric ulcer were significantly higher. The serum PG I levels of gastritis patients were significantly lower and the serum PG I levels and PG I/PG II ratio of gastric cancer patients were much more lower. After total gastrectomy, the serum PG I and PG II levels of patients with recurrence of gastric cancer were significantly higher than those without recurrence. The changes of serum PG I and PG II levels are valuable for the diagnosis of gastric cancer and detecting the recurrence of gastric cancer after total gastrectomy

    Full Text Available BACKGROUND: Activation of the Wnt signaling pathway is implicated in aberrant cellular proliferation in various cancers. In 40% of endometrioid ovarian cancers, constitutive activation of the pathway is due to oncogenic mutations in β-catenin or other inactivating mutations in key negative regulators. Secreted frizzled-related protein 4 (SFRP4 has been proposed to have inhibitory activity through binding and sequestering Wnt ligands. METHODOLOGY/PRINCIPAL FINDINGS: We performed RT-qPCR and Western-blotting in primary cultures and ovarian cell lines for SFRP4 and its key downstream regulators activated β-catenin, β-catenin and GSK3β. SFRP4 was then examined by immunohistochemistry in a cohort of 721 patients and due to its proposed secretory function, in plasma, presenting the first ELISA for SFRP4. SFRP4 was most highly expressed in tubal epithelium and decreased with malignant transformation, both on RNA and on protein level, where it was even more profound in the membrane fraction (p<0.0001. SFRP4 was expressed on the protein level in all histotypes of ovarian cancer but was decreased from borderline tumors to cancers and with loss of cellular differentiation. Loss of membrane expression was an independent predictor of poor survival in ovarian cancer patients (p = 0.02 unadjusted; p = 0.089 adjusted, which increased the risk of a patient to die from this disease by the factor 1.8. CONCLUSIONS/SIGNIFICANCE: Our results support a role for SFRP4 as a tumor suppressor gene in ovarian cancers via inhibition of the Wnt signaling pathway. This has not only predictive implications but could also facilitate a therapeutic role using epigenetic targets.

    Objective Psychotherapy is a common non-pharmacological approach to help cancer patients in their psychological distress. The benefit of psychotherapies was documented, but the types of psychotherapies proposed are varied. Given that the previous literature review was a decade ago and no quantitative analysis was done on this topic, we again critically and systematically reviewed all published trials on psychotherapy in cancer patients. Method We identified 17 clinical trials on six types of psychotherapy for cancer patients by searching PubMed and EMBASE. Result There were four trials involved adjunct psychological therapy which were included in quantitative analysis. Each trial demonstrated that psychotherapy improved the quality of life and coping in cancer patients. There was also a reduction in distress, anxiety, and depression after a psychological intervention. However, the number and quality of clinical trials for each type of psychotherapy were poor. The meta-analysis of the four trials involved adjunct psychological therapy showed no significant change in depression, with only significant short-term improvement in anxiety but not up to a year-the standardized mean differences were -0.37 (95% confidence interval (CI) = -0.57, -0.16) at 2 months, -0.21 (95% CI = -0.42, -0.01) at 4 months, and 0.03 (95 % CI = -0.19, 0.24) at 12 months. Conclusion The evidence on the efficacy of psychotherapy in cancer patients is unsatisfactory. There is a need for more rigorous and well-designed clinical trials on this topic.

The publishing language was limited to English. The quality of included articles was evaluated according to the Quality Assessment of Diagnosis Accuracy Studies-2 (QUADAS-2. The correlation coefficient (r was extracted from the included articles and processed by Fisher's r-to-z transformation. The combined correlation coefficient (r and the 95% confidence interval (CI were calculated with STATA 11.0 software under a random-effects model. Begg's test was used to analyze the existence of publication bias and draw funnel plot, and the sources of heterogeneity were explored by sensitivity and subgroup analyses.According to the inclusion and exclusion criteria, 79 articles were finally included, including 81 studies involving a total of 3242 patients. All the studies had a combined r of 0.44 (95% CI, 0.41-0.46, but with a significant heterogeneity (I2 = 80.9%, P<0.01. Subgroup analysis for different tumor types indicated that most subgroups showed a reduced heterogeneity. Malignant melanoma (n = 1 had the minimum correlation coefficient (-0.22 between 18F-FDG uptake and Ki-67 expression, while the thymic epithelial tumors (TETs; n = 2 showed the maximum correlation coefficient of 0.81. The analytical results confirmed that correlation between 18F-FDG uptake and Ki-67 expression was extremely significant in TETs, significant in gastrointestinal stromal tumors (GISTs, moderate in patients with lung, breast, bone and soft tissue, pancreatic, oral, thoracic, and uterine and ovarian cancers, average in brain, esophageal and colorectal

    Purpose: This pilot study investigates the role of DOC-2/DAB2 Interacting Protein (DAB2IP) and enhancer of zeste homolog 2 (EZH2) as prognostic biomarkers in high-risk prostate cancer patients receiving definitive radiation therapy. Methods and Materials: Immunohistochemistry was performed and scored by an expert genitourinary pathologist. Clinical endpoints evaluated were freedom from biochemical failure (FFBF), castration resistance–free survival (CRFS), and distant metastasis–free survival (DMFS). Log-rank test and Cox regression were used to determine significance of biomarker levels with clinical outcome. Results: Fifty-four patients with high-risk prostate cancer (stage ≥T3a, or Gleason score ≥8, or prostate-specific antigen level ≥20 ng/mL) treated with radiation therapy from 2005 to 2012 at our institution were evaluated. Nearly all patients expressed EZH2 (98%), whereas 28% of patients revealed DAB2IP reduction and 72% retained DAB2IP. Median follow-up was 34.0 months for DAB2IP-reduced patients, 29.9 months for DAB2IP-retained patients, and 32.6 months in the EZH2 study. Reduction in DAB2IP portended worse outcome compared with DAB2IP-retained patients, including FFBF (4-year: 37% vs 89%, P=.04), CRFS (4-year: 50% vs 90%, P=.02), and DMFS (4-year: 36% vs 97%, P=.05). Stratified EZH2 expression trended toward significance for worse FFBF and CRFS (P=.07). Patients with reduced DAB2IP or highest-intensity EZH2 expression exhibited worse FFBF (4-year: 32% vs 95%, P=.02), CRFS (4-year: 28% vs 100%, P<.01), and DMFS (4-year: 39% vs 100%, P=.04) compared with the control group. Conclusion: Loss of DAB2IP is a potent biomarker that portends worse outcome despite definitive radiation therapy for patients with high-risk prostate cancer. Enhancer of zeste homolog 2 is expressed in most high-risk tumors and is a less potent discriminator of outcome in this study. The DAB2IP status in combination with degree of EZH2 expression may be useful for

    Early identification of mutations may guide patients with metastatic colorectal cancer toward targeted therapies that may be life prolonging. The authors assessed tumor genotype correlations with clinical characteristics to determine whether mutational profiling can account for clinical similarities, differences, and outcomes. Under Institutional Review Board approval, 222 patients with metastatic colon adenocarcinoma (n = 158) and rectal adenocarcinoma (n = 64) who underwent clinical tumor genotyping were reviewed. Multiplexed tumor genotyping screened for >150 mutations across 15 commonly mutated cancer genes. The chi-square test was used to assess genotype frequency by tumor site and additional clinical characteristics. Cox multivariate analysis was used to assess the impact of genotype on overall survival. Broad-based tumor genotyping revealed clinical and anatomic differences that could be linked to gene mutations. NRAS mutations were associated with rectal cancer versus colon cancer (12.5% vs 0.6%; P colon cancer (13% vs 3%; P = .024) and older age (15.8% vs 4.6%; P = .006). TP53 mutations were associated with rectal cancer (30% vs 18%; P = .048), younger age (14% vs 28.7%; P = .007), and men (26.4% vs 14%; P = .03). Lung metastases were associated with PIK3CA mutations (23% vs 8.7%; P = .004). Only mutations in BRAF were independently associated with decreased overall survival (hazard ratio, 2.4; 95% confidence interval, 1.09-5.27; P = .029). The current study suggests that underlying molecular profiles can differ between colon and rectal cancers. Further investigation is warranted to assess whether the differences identified are important in determining the optimal treatment course for these patients. © 2014 American Cancer Society.

    Olaparib (O), a polyADPribose polymerase (PARP) inhibitor, and cediranib (C), a VEGF receptor (VEGFR)1-3 inhibitor together had greater activity than O alone in women with recurrent platinum-sensitive ovarian cancer (OvCa). The objective of this study is to identify potential lead biomarker candidates for response to O + C in the setting of a multi-institutional phase II study of O with and without C in recurrent platinum-sensitive OvCa. A self-selected group of patients participated in a prospectively planned exploratory biomarker substudy of the randomized phase II study of O versus O + C. Whole blood for peripheral blood mononuclear cell (PBMC) and plasma isolation was collected prior to and on day 3 of treatment. Quantitation of circulating endothelial cells (CEC), IL-6, IL-8, VEGF, and soluble VEGFR-2 plasma concentrations, and polyADPribose (PAR) incorporation were performed. Single nucleotide polymorphism analysis of XRCC1 280H, R194W, and Q399R was done. Dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI) was performed at baseline and day 3 of treatment. Parameter changes were compared between the two arms using an exact Wilcoxon rank sum test. Kaplan-Meier and log-rank tests were used to examine survival outcome. Thirteen patients elected to participate in the translational substudy, seven patients on O and six patients on O + C. Patients on O + C had a greater decrease in IL-8 concentration and larger CEC fold increase compared with those on O alone (p = 0.026, p = 0.032). The fold increase in CEC on day 3 was associated with duration of progression-free survival (PFS) (R (2) = 0.77, 95% CI 0.55-0.97, p < 0.001). IL-8 post-pretreatment changes correlate with PFS (p = 0.028). XRCC1 DNA polymorphisms were not related to PFS. All patients had reduction in PAR incorporation, and all except one had reduction in vascular flow on DCE-MRI. Our exploratory correlative studies indicate that CEC and IL-8 changes may be

    To evaluate the changes of perioperative plasma concentrations of Aβ 1-40 and S-100β to determine the relationship with postoperative cognitive dysfunction in elderly patients undergoing oral and maxillofacial cancer surgeries. One hundred and fifteen patients aged at least 60 years undergoing oral and maxillofacial tumor resection were investigated between May 2014 to December 2014.Neuropsychological tests for detecting postoperative cognitive dysfunction(POCD) were performed one day before surgery and 7 days postoperatively. According to the results of neuropsychological tests on day 7, patients were divided into POCD group and non-POCD group.Plasma values of Aβ 1-40 and S-100β were determined with enzyme linked immunosorbent assay (ELISA) before anesthesia induction, 24 h and 7 days after surgery. The data were analyzed using SPSS 19.0 software package. According to the definition, POCD was present in 37 of 115 (32.3%) patients 1 week after surgery. Compared with pre-anesthesia, S-100β levels in POCD group were significantly increased (Psurgery (Poral and maxillofacial surgeries with general anesthesia. The increasing levels of Aβ 1-40 , S-100β may be associated with the occurence of POCD. Patients with long-lasting operation and high concentrations of Aβ 1-40 and S-100β after surgeries were at a higher risk of POCD. The clinical values of Aβ 1-40 and S-100 as predictive measurements of POCD after oral and maxillofacial cancer surgery appear to be reasonable.

    Jensen, Kenneth; Bonde Jensen, Anders; Grau, Cai

    2006-01-01

    Background and purpose: Morbidity is an important issue in cancer research. The observer-based toxicity scoring system used by DAHANCA (the Danish head and neck cancer study group) has proved itself sensitive to differences in toxicity in a large randomised study, but like other toxicity scoring systems it has not been formally validated. Conversely, the EORTC quality of life questionnaire (QLQ) has been validated as a tool for collecting information about the consequences of disease and treatment on the well being of cancer patients. The purpose of this study was to examine the relationship between the two methods of side effect recording. Patients and methods: One hundred and sixteen recurrence free patients with laryngeal (n=44), pharyngeal (n=34) and oral cavity (n=38) cancer attending follow-up after radiotherapy (n=83) or surgery (n=33) completed EORTC C30, the core questionnaire concerning general symptoms and function and EORTC H and N35 the head and neck specific questionnaire. The attending physicians in the follow-up clinic evaluated and recorded DAHANCA toxicity scores on the same patients. Results: The DAHANCA toxicity scoring system and the EORTC QLQ correlated with several clinical endpoints. The conceptually similar endpoints of the two methods correlated significantly. The objective endpoints of the DAHANCA scoring system were only correlated with quality of life endpoints to a very low degree. The DAHANCA toxicity scores had a low sensitivity (0.48-0.74) in detecting equivalent subjective complaints from the questionnaires and the observer-based scoring system severely underestimated patient complaints. A specific patient group where the DAHANCA score had a higher tendency to fail could not be detected. Conclusion: The DAHANCA toxicity score is an effective instrument in assessing objective treatment induced toxicity in head and neck cancer patients but insensitive and non-specific with regard to patient assessed subjective endpoints.

    INTRODUCTION: Lung cancer remains a leading cause of cancer-related death. The incidence increases with age and the occurrence in young patients is relatively low. The clinicopathological features of lung cancer in younger patients have not been fully explored previously. METHODS: To assess the age...... differences in the clinical characteristics of lung cancer, we conducted a retrospective analysis comparing young patients ≤ 65 years of age with an elderly group > 65 years of age. Among 1,232 patients evaluated due to suspicion of lung cancer in our fast-track setting from January-December 2013, 312 newly...... diagnosed lung cancer patients were included. RESULTS: Patients ≤ 65 years had a significantly higher representation of females (p = 0.0021), more frequent familial cancer aggregation (p = 0.028) and a lower incidence of squamous cell carcinoma (p = 0.0133). When excluding pure carcinoid tumours...

    Full text: Objective: To correlate 18F-FDG PET metabolic response to therapy with histopathology and survival, in patients with locally advanced (stage IIl) non-small cell lung carcinoma (NSCLC) receiving induction chemotherapy. Methods: A retrospective review of all patients with stage III NSCLC planned for induction chemotherapy and surgical resection, in whom pre- and post-chemotherapy FDG-PET at Austin Health between 2004 and 2007 was performed. The staging and positive nodal stations as determined by PET was compared to histopathological findings after resection. The tumour response on serial FDG PET was also compared to overall outcome. Results: 9 patients were included. There was a 100 % correlation between pre- or post- chemotherapy nodal staging and final histopathological nodal stage. Ninety percent of all positive nodal stations (9/10) seen on histopathology were correctly localised by pre- or post-chemotherapy FDG PET. Only one patient with a metastatic lymph node at nodal station 9 R could not be localised by prior PET studies. Of the patients in whom a down-staging in tumour status was observed on the postchemotherapy FDG-PET, 83% (5/6) of patients were still alive (follow-up range of 8 to 40 months) as compared with 33% (1/3 ) (follow-up range of 9-13 months) for non-responders. Conclusion: There is good correlation between pre- and/or post- chemotherapy FDG PET and final histopathology for the nodal staging of stage III NSCLC. There is an overall trend for those patients in whom PET resulted in a down-staging of tumour to have a longer survival.

    To prospectively evaluate if the perfusion parameters of gastric cancer can provide information on histologic subtypes of gastric cancer. We performed preoperative perfusion CT (PCT) and curative gastrectomy in 46 patients. PCT data were analysed using a dedicated software program. Perfusion parameters were obtained by two independent radiologists and were compared according to histologic type using Kruskal-Wallis, Mann-Whitney U test and receiver operating characteristic analysis. To assess inter-reader agreement, we used intraclass correlation coefficient (ICC). Inter-reader agreement for perfusion parameters was moderate to substantial (ICC = 0.585-0.678). Permeability surface value of poorly cohesive carcinoma (PCC) was significantly higher than other histologic types (47.3 ml/100 g/min in PCC vs 26.5 ml/100 g/min in non-PCC, P < 0.001). Mean transit time (MTT) of PCC was also significantly longer than non-PCC (13.0 s in PCC vs 10.3 s in non-PCC, P = 0.032). The area under the curve to predict PCC was 0.891 (P < 0.001) for permeability surface and 0.697 (P = 0.015) for MTT. Obtaining perfusion parameters from PCT was feasible in gastric cancer patients and can aid in the preoperative imaging diagnosis of PCC-type gastric cancer as the permeability surface and MTT value of PCC type gastric cancer were significantly higher than those of non-PCC.

    To study the correlation between 18F-FDG uptake and cell proliferation in cancer patients by meta-analysis of published articles. We searched PubMed (MEDLINE included), EMBASE, and Cochrane Database of Systematic Review, and selected research articles on the relationship between 18F-FDG uptake and Ki-67 expression (published between August 1, 1994-August 1, 2014), according to the literature inclusion and exclusion criteria. The publishing language was limited to English. The quality of included articles was evaluated according to the Quality Assessment of Diagnosis Accuracy Studies-2 (QUADAS-2). The correlation coefficient (r) was extracted from the included articles and processed by Fisher's r-to-z transformation. The combined correlation coefficient (r) and the 95% confidence interval (CI) were calculated with STATA 11.0 software under a random-effects model. Begg's test was used to analyze the existence of publication bias and draw funnel plot, and the sources of heterogeneity were explored by sensitivity and subgroup analyses. According to the inclusion and exclusion criteria, 79 articles were finally included, including 81 studies involving a total of 3242 patients. All the studies had a combined r of 0.44 (95% CI, 0.41-0.46), but with a significant heterogeneity (I2 = 80.9%, Ppositron emission tomography (PET) or PET/CT imaging technology or Ki-67 and standardized uptake value (SUV) measurement technology did not significantly affect the results of r values, and Begg's test showed no significant publication bias. In cancer patients, 18F-FDG uptake showed a moderate positive correlation with tumor cell proliferation. Different tumor types exhibited varied degree of correlation, and the correlation was significant in TETs and GSTs. However, our results need further validation by clinical trials with a large sample of different tumor types.

    Family history of cancer is a risk factor for gastric cancer. In this study, we investigated the prognoses of gastric cancer patients with family history of cancer. A total of 1805 gastric cancer patients who underwent curative gastrectomy from 2000 to 2008 were evaluated. The clinicopathologic parameters and prognoses of gastric cancer patients with a positive family history (PFH) of cancer were compared with those with a negative family history (NFH). Of 1805 patients, 382 (21.2%) patients had a positive family history of cancer. Positive family history of cancer correlated with younger age, more frequent alcohol and tobacco use, worse differentiation, smaller tumor size, and more frequent tumor location in the lower 1/3 of the stomach. The prognoses of patients with a positive family history of cancer were better than that of patients with a negative family history. Family history of cancer independently correlated with better prognosis after curative gastrectomy in gastric cancer patients.

    Full Text Available Poor prognosis for late-stage, high-grade, and recurrent cancers has been motivating cancer researchers to search for more efficient biomarkers to identify the onset of cancer. Recent advances in constructing and dynamically analyzing biomolecular networks for different types of cancer have provided a promising novel strategy to detect tumorigenesis and metastasis. The observation of different biomolecular networks associated with normal and cancerous states led us to hypothesize that correlations for gene expressions could serve as valid indicators of early cancer development. In this pilot study, we tested our hypothesis by examining whether the mRNA expressions of three randomly selected cancer-related genes PIK3C3, PIM3, and PTEN were correlated during cancer progression and the correlation coefficients could be used for cancer diagnosis. Strong correlations (0.68≤r≤1.0 were observed between PIK3C3 and PIM3 in breast cancer, between PIK3C3 and PTEN in breast and ovary cancers, and between PIM3 and PTEN in breast, kidney, liver, and thyroid cancers during disease progression, implicating that the correlations for cancer network gene expressions could serve as a supplement to current clinical biomarkers, such as cancer antigens, for early cancer diagnosis.

    Full Text Available Abstract Background Early relapse in colorectal cancer (CRC patients is attributed mainly to the higher malignant entity (such as an unfavorable genotype, deeper tumor invasion, lymph node metastasis and advance cancer stage and poor response to chemotherapy. Several investigations have demonstrated that genetic polymorphisms in drug-targeted genes, metabolizing enzymes, and DNA-repairing enzymes are all strongly correlated with inter-individual differences in the efficacy and toxicity of many treatment regimens. This preliminary study attempts to identify the correlation between genetic polymorphisms and clinicopathological features of CRC, and evaluates the relationship between genetic polymorphisms and chemotherapeutic susceptibility of Taiwanese CRC patients. To our knowledge, this study discusses, for the first time, early cancer relapse and its indication by multiple genes. Methods Six gene polymorphisms functional in drug-metabolism – GSTP1 Ile105Val, ABCB1 Ile1145Ile, MTHFR Ala222Val, TYMS double (2R or triple (3R tandem repeat – and DNA-repair genes – ERCC2 Lys751Gln and XRCC1 Arg399Gln – were assessed in 201 CRC patients using a polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP technique and DNA sequencing. Patients were diagnosed as either high-risk stage II (T2 and 3 N0 M0 or III (any T N1 and 2 M0 and were administered adjuvant chemotherapy regimens that included 5-fluorouracil (5FU and leucovorin (LV. The correlations between genetic polymorphisms and patient clinicopathological features and relapses were investigated. Results In this study, the distributions of GSTP1 (P = 0.003, ABCB1 (P = 0.001, TYMS (P ERCC2 (P XRCC1 (P = 0.006 genotypes in the Asian population, with the exception of MTHFR (P = 0.081, differed significantly from their distributions in a Caucasian population. However, the unfavorable genotype ERCC2 2251A>C (P = 0.006, tumor invasion depth (P = 0.025, lymph node metastasis (P = 0

    Purpose: To investigate the association of high-dose preoperative chemoradiotherapy (CRT) and dose-volume histogram (DVH) parameters of lungs with incidence of postoperative pulmonary complications and to identify predictive clinical factors of pulmonary complications. Methods: Data of 65 patients were collected retrospectively. Thirty-five patients underwent transthoracic esophagectomy (TTE) alone and 30 received cisplatin and 5-fluorouracil, concomitant with radiotherapy, median dose 66 Gy, and followed by TTE. From the DVH for each lung alone and for both lungs together as one organ we generated total lung volume, mean radiotherapy dose, relative and absolute volumes receiving more than a threshold dose, and relative and absolute volumes receiving less than a threshold dose. Postoperative pulmonary complications were defined as pneumonia or respiratory failure. Results: Sixty percent of the patients in the TTE alone group had postoperative pulmonary complications versus 63% in the CRT + TTE group. Postoperative mortality was 8.6% and 16.7% in the respective patient groups (p = NS). None of the DVH parameters was associated with postoperative pulmonary complications. Squamous cell carcinoma was an adverse factor related to increased postoperative pulmonary complications. Conclusion: High-dose preoperative CRT was not associated with increased postoperative pulmonary complications in this cohort of esophageal cancer patients.

    National colorectal cancer (CRC) screening rates have plateaued. To optimize interventions targeting those unscreened, a better understanding is needed of how this preventive service fits in with multiple preventive and chronic care needs managed by primary care providers (PCPs). This study examines whether PCP practices of other preventive and chronic care needs correlate with CRC screening. We performed a retrospective cohort study of 90 PCPs and 33,137 CRC screening-eligible patients. Five PCP quality metrics (breast cancer screening, cervical cancer screening, HgbA1c and LDL testing, and blood pressure control) were measured. A baseline correlation test was performed between these metrics and PCP CRC screening rates. Multivariable logistic regression with clustering at the clinic-level estimated odds ratios and 95% confidence intervals for these PCP quality metrics, patient and PCP characteristics, and their relationship to CRC screening. PCP CRC screening rates have a strong correlation with breast cancer screening rates (r = 0.7414, p < 0.001) and a weak correlation with the other quality metrics. In the final adjusted model, the only PCP quality metric that significantly predicted CRC screening was breast cancer screening (OR 1.25; 95% CI 1.11-1.42; p < 0.001). PCP CRC screening rates are highly concordant with breast cancer screening. CRC screening is weakly concordant with cervical cancer screening and chronic disease management metrics. Efforts targeting PCPs to increase CRC screening rates could be bundled with breast cancer screening improvement interventions to increase their impact and success.

    Hepatocyte growth factor receptor/c-Met is associated with malignant aggressiveness and survival in various cancers including bladder cancer. Although phosphorylation of hepatocyte growth factor receptor/c-Met is essential for its function, the pathologic significance of phosphorylated hepatocyte growth factor receptor/c-Met in bladder cancer remains elusive. We investigated the clinical significance of its expression, and its correlation with cancer cell progression-related molecules. The expression levels of 2 tyrosine residues of hepatocyte growth factor receptor/c-Met (pY1234/1235 and pY1349) were examined immunohistochemically in 133 specimens with nonmetastatic bladder cancer. We also investigated their correlation with matrix metalloproteinase-1, -2, -7, and -14; urokinase-type plasminogen activator; E-cadherin; CD44 standard, variant 3, and variant 6; and vascular endothelial growth factor. Expression of phosphorylated hepatocyte growth factor receptor/c-Met was detected in cancer cells, but was rare in normal urothelial cells. Although hepatocyte growth factor receptor/c-Met, pY1234/1235 hepatocyte growth factor receptor/c-Met, and pY1349 hepatocyte growth factor receptor/c-Met were associated with pT stage, multivariate analysis identified pY1349 hepatocyte growth factor receptor/c-met expression only as a significant factor for high pT stage. Expression of pY1349 hepatocyte growth factor receptor/c-Met was a marker of metastasis and (P = .001) and cause-specific survival (P = .003). Expressions of matrix metalloproteinase-2, matrix metalloproteinase-7, and E-cadherin correlated with pY1349 hepatocyte growth factor receptor/c-Met expression. Our results demonstrated that pY1349 hepatocyte growth factor receptor/c-Met plays an important role in tumor development, and its expression is a significant predictor of metastasis and survival of patients with bladder cancer. The results suggest that these activities are mediated, at least in part, by matrix

    In the previous study, a statistically significant positive correlation between natural background radiation exposure rates and crude (non-age-adjusted) cancer mortality rates was observed in 46 Japanese prefectures over the period from 1968 until 1978. In the present investigation, however, the significance of this correlation mostly disappeared through age adjustment with only the two exceptions of female stomach and uterine cancers. Age adjusted male esophagus cancer mortality rate still showed a significant negative correlation. Female esophagus and pancreas cancers became negatively correlated with exposure rate through age adjustment. It was suggested that natural radiation levels are positively correlated with prefectural population component ratios older than 40, 50 and 65 years, which was considered to be one of the causes of apparent correlation between exposure rates and crude cancer mortality rates.

    Purpose: To evaluate the severity of cetuximab-induced skin rash and its correlation with clinical outcome and late skin toxicity in patients with head and neck squamous cell carcinoma treated with chemoradiation therapy and cetuximab. Methods and Materials: Analysis included patients who received loading dose and ≥1 cetuximab dose concurrent with definitive chemoradiation therapy (70 Gy + cisplatin) or postoperative chemoradiation therapy (60-66 Gy + docetaxel or cisplatin). Results: Six hundred two patients were analyzed; 383 (63.6%) developed grade 2 to 4 cetuximab rash. Patients manifesting grade 2 to 4 rash had younger age (P<.001), fewer pack-years smoking history (P<.001), were more likely to be males (P=.04), and had p16-negative (P=.04) oropharyngeal tumors (P=.003). In univariate analysis, grade 2 to 4 rash was associated with better overall survival (hazard ratio [HR] 0.58, P<.001) and progression-free survival (HR 0.75, P=.02), and reduced distant metastasis rate (HR 0.61, P=.03), but not local-regional failure (HR 0.79, P=.16) relative to grade 0 to 1 rash. In multivariable analysis, HRs for overall survival, progression-free survival, distant metastasis, and local-regional failure were, respectively, 0.68 (P=.008), 0.85 (P=.21), 0.64 (P=.06), and 0.89 (P=.48). Grade ≥2 rash was associated with improved survival in p16-negative patients (HR 0.28 [95% confidence interval 0.11-0.74]) but not in p16-positive patients (HR 1.10 [0.42-2.89]) (P=.05 for interaction). Twenty-five percent of patients with grade 2 to 4 acute in-field radiation dermatitis experienced grade 2 to 4 late skin fibrosis, versus 14% of patients with grade 0 to 1 acute in-field radiation dermatitis (P=.002). Conclusion: Grade 2 to 4 cetuximab rash was associated with better survival, possibly due to reduction of distant metastasis. This observation was noted mainly in p16-negative patients. Grade 2 to 4 acute in-field radiation dermatitis was associated with higher rate of

    131 I whole-body scan (WBS) and serum thyroglobulin (TG) are important in detecting thyroid remnants or recurrent disease in patients with differentiated thyroid cancer. Usually, a diagnostic WBS is carried out 6 months after ablation to exclude residual disease. We retrospectively analysed results of a second routine diagnostic WBS and TG measurements at 1 year after thyroablation and correlated these to the risk profile of patients with long-term follow-up. A total of 197 patients were followed up after thyroidectomy and ablative 131 I therapy. Follow-up included clinical examination, radioiodine WBS and thyroid-stimulating hormone (TSH), free thyroxine and TG measurements at 3-6 months and 1 year after ablation. WBS (+) patients received a therapeutic activity of 131 I. The risk profile of patients was defined according to clinical results before the 1-year control. Clinical results at 1 year after ablation were analysed in correlation to the patient risk profile and long-term follow-up data (mean 7.2 years). One year after thyroablation, 95.8% of low-risk patients had no residual disease when diagnostic WBS was carried out using 370 MBq 131 I; 4.2% of low-risk patients had residual disease at this time point. In the high-risk group of this cohort, 54.5% were disease-free 1 year after ablation, but 45.5% demonstrated residual disease. After the 1-year control, 94% of all applied radioiodine therapies were executed in the high-risk group, compared with 6% in the low-risk group (p < 0.01). A second routine WBS 1 year after thyroablation is not indicated in low-risk patients. Risk stratification according to the early clinical course effectively identified patients with higher likelihood of persistent or recurrent disease in the long-term follow-up. (orig.)

    Alterations of the beta subunit of tubulin have been reported to be predictive of resistance to radiation and antitubulin agents in several solid tumors. The aim of the study was to investigate the clinical role of beta III tubulin expression as prognostic factor for survival and as a predictive parameter of response to preoperative radiochemotherapy in a single institutional series of locally advanced cervical cancer (LACC) patients. The study included 98 LACC patients admitted to the Gynecologic Oncology Unit, Catholic University of Rome and Campobasso between January 1998 and January 2005. Immunohistochemistry was performed by using the polyclonal rabbit anti-beta III tubulin antibody (Covance, Princeton, NJ, USA). The value of 10% immunostained tumor cells was arbitrarily chosen as cut-off value to distinguish cases with high versus low beta III tubulin content. In the whole series, beta III tubulin immunoreaction was detectable in 66/98 cases (67.3%), and the percentage of positively stained cells ranged from 0 to 100% (median=10%). The percentages of cases with high beta III tubulin expression were shown not to be differently distributed according to clinico-pathological characteristics. There was no statistically significant difference in the distribution of cases with high beta III tubulin expression according to clinical and pathological response to treatment. During the follow-up period, recurrence and death of disease occurred in 15 and 13 cases, respectively. There was no difference in disease-free and overall survival in cases with high versus low beta III tubulin expression. The assessment of class III beta tubulin status seems of little usefulness in order to identify LACC patients with poor chance of response to concomitant radiochemotherapy and unfavorable prognosis.

    To report design of a simplified external transmit-receive coil array for 7 Tesla (T) prostate MRI, including demonstration of the array for tumor localization using T2-weighted imaging (T2WI) at 7T before prostatectomy. Following simulations of transmitter designs not requiring parallel transmission or radiofrequency-shimming, a coil array was constructed using loop elements, with anterior and posterior rows comprising one transmit-receive element and three receive-only elements. This coil structure was optimized using a whole-body phantom. In vivo sequence optimization was performed to optimize achieved flip angle (FA) and signal to noise ratio (SNR) in prostate. The system was evaluated in a healthy volunteer at 3T and 7T. The 7T T2WI was performed in two prostate cancer patients before prostatectomy, and localization of dominant tumors was subjectively compared with histopathological findings. Image quality was compared between 3T and 7T in these patients. Simulations of the B1(+) field in prostate using two-loop design showed good magnitude (B1(+) of 0.245 A/m/w(1/2)) and uniformity (nonuniformity [SD/mean] of 10.4%). In the volunteer, 90° FA was achieved in prostate using 225 v 1 ms hard-pulse (indicating good efficiency), FA maps confirmed good uniformity (14.1% nonuniformity), and SNR maps showed SNR gain of 2.1 at 7T versus 3T. In patients, 7T T2WI showed excellent visual correspondence with prostatectomy findings. 7T images demonstrated higher estimated SNR (eSNR) in benign peripheral zone (PZ) and tumor compared with 3T, but lower eSNR in fat and slight decreases in tumor-to-PZ contrast and PZ-homogeneity. We have demonstrated feasibility of a simplified external coil array for high-resolution T2-weighted prostate MRI at 7T. © 2013 Wiley Periodicals, Inc.

    Cancer cachexia is a debilitating condition and results in poor prognosis. The purpose of this study was to assess hospitalization incidence, patient characteristics, and medical cost and burden of cancer cachexia in the US. This study used a cross-sectional analysis of the Nationwide Inpatient Sample (NIS) for 2009. Five cancers reported to have the highest cachexia incidence were assessed. The hospitalization incidence related to cachexia was estimated by cancer type, cost and length of stay were compared, and descriptive statistics were reported for each cancer type, as well as differences being compared between patients with and without cachexia. Risk of inpatient death was higher for patients with cachexia in lung cancer (OR = 1.32; CI = 1.20-1.46) and in all cancers combined (OR = 1.76; CI = 1.67-1.85). The presence of cachexia increased length of stay in lung (IRR = 1.05; CI = 1.03-1.08), Kaposi's sarcoma (IRR = 1.47; CI = 1.14-1.89) and all cancers combined (IRR = 1.09; CI = 1.08-1.10). Additionally, cachectic patients in the composite category had a longer hospitalization stay compared to non-cachectic patients (3-9 days for those with cachexia and 2-7 days for those without cachexia). The cost of inpatient stay was significantly higher in cachexic than non-cachexic lung cancer patients ($13,560 vs $13 190; p Cachexia increases hospitalization costs and length of stay in several cancer types. Identifying the medical burden associated with cancer cachexia will assist in developing an international consensus for recognition and coding by the medical community and ultimately an effective treatment plans for cancer cachexia.

    Full Text Available Objectives. The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. Study design. The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort. Methods. The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling. Results. There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30 and for non-Sami 1.02 (0.86–1.20, indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. Conclusion. Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland.

    Sexuality is a basic need for every human being as long as he or she is alive, irrespective of age or health status. Approximately 23,500 individuals are diagnosed with cancer each year in Israel and join the 120,000 cancer patients currently living in Israel. The results of cancer treatments are traditionally assessed and based on the outcome regarding mortality versus survival. An equally important aspect to be addressed in this assessment must relate to quality of life. One of the more painful insults to the quality of life of cancer patients relates to the deleterious effects on sexuality. This article aims to present physicians with the spectrum of sexuality-related issues which are encountered by cancer patients and their partners, starting from the moment of diagnosis, throughout the various stages of treatment and to provide basic knowledge. Many individuals contracting cancer have difficulty dealing with the issue of sexuality. They are typically embarrassed and feel uneasy when asking health care providers about such a non-life threatening issue. Partners similarly feel both shame and guilt. In many cases sexuality, intimacy and emotional attachment are important aspects and may be essential for survival. Addressing these issues during treatment can provide patients with a sense of security, avoiding embarrassment and further exacerbation of such problems. Unfortunately, little has been done to develop an optimal interventional program, although standard sexual treatments have often been applied. Prospective clinical research and outcomes are missing. The physician can use the well-known PLISSIT model (1978): to provide sexuality involvement on different levels. The very new BETTER model (2004) can help emphasize that cancer treatment and the disease have an influence on intimacy and sexuality.

    Tomographic images, specifically the contrasted chest tomographies, were examined in patients diagnosed in patients diagnosed with lung cancer at the Hospital San Juan de Dios during the years 2011 and 2012. The primitive tomographic behavior of lung cancer was evaluated in order to determine and characterize its presentation pattern. Each histological type of lung cancer was determined. The stage of lung cancer was classified according to the International System of Staging Tumor, Node and Metastasis. An analysis of the incidence and stage of lung cancer at the time of diagnosis was made, evidencing the fundamental role of chest tomography in the screening, diagnosis, management and control of patients with primary pulmonary neoplasia [es

    To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = - 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

    Full Text Available Intoduction: Melanosis coli is a benign lesion affecting the mucosa of the large intestine. There is a relationship between the presence of melanosis and anthraquinone laxative use. Melanosis coli is also observed in patients with colon cancer, but there is doubt whether these two conditions are related. Aim : To analyze the correlation between melanosis and colon cancer. Material and methods: We analyzed retrospectively 436 patients undergoing colon cancer surgery. There were 246 women and 190 men. Patients were divided into three age groups: under 50 years, between 51 and 65 years, and over 66 years. We analyzed sections of the cancer and intestinal mucosa from the tumor’s proximal (2–5 cm and distal (8–10 cm zone. Results : Melanosis coli was present in 52 patients, which represents 11.9% of patients with colon cancer. More often it was present in women. The most common location of melanosis and colon cancer was the terminal part of the large intestine. In patients below 50 years of age in both sexes melanosis coli did not occur. In men, melanosis was more common in the age group over 66 years. Intensity of pigmentation was higher in the tumor’s distal zone. Conclusions : The incidence of melanosis coli increases with age, similar to that of colon cancer. Melanosis was not present inside tumors, in almost half of the cases it was not present in the proximal zone, and the degree of pigmentation increased in distal zone. The cause-effect relationship between melanosis coli and colon cancer remains uncertain.

    The aim of this study was to evaluate the correlation between the ‘true’ absolute and relative dose–volume histograms (DVHs) of the bladder wall, dose–wall histogram (DWH) defined on MRI imaging and other surrogates of bladder dosimetry in prostate cancer patients, planned both with 3D-conformal and intensity-modulated radiation therapy (IMRT) techniques. For 17 prostate cancer patients, previously treated with radical intent, CT and MRI scans were acquired and matched. The contours of bladder walls were drawn by using MRI images. External bladder surfaces were then used to generate artificial bladder walls by performing automatic contractions of 5, 7 and 10 mm. For each patient a 3D conformal radiotherapy (3DCRT) and an IMRT treatment plan was generated with a prescription dose of 77.4 Gy (1.8 Gy/fr) and DVH of the whole bladder of the artificial walls (DVH-5/10) and dose–surface histograms (DSHs) were calculated and compared against the DWH in absolute and relative value, for both treatment planning techniques. A specific software (VODCA v. 4.4.0, MSS Inc.) was used for calculating the dose–volume/surface histogram. Correlation was quantified for selected dose–volume/surface parameters by the Spearman correlation coefficient. The agreement between %DWH and DVH5, DVH7 and DVH10 was found to be very good (maximum average deviations below 2%, SD < 5%): DVH5 showed the best agreement. The correlation was slightly better for absolute (R = 0.80–0.94) compared to relative (R = 0.66–0.92) histograms. The DSH was also found to be highly correlated with the DWH, although slightly higher deviations were generally found. The DVH was not a good surrogate of the DWH (R < 0.7 for most of parameters). When comparing the two treatment techniques, more pronounced differences between relative histograms were seen for IMRT with respect to 3DCRT (p < 0.0001). (note)

    Trastuzumab prolongs survival in HER2 positive breast cancer patients. However, resistance remains a challenge. We have previously shown that ADAM17 plays a key role in maintaining HER2 phosphorylation during trastuzumab treatment. Beside ADAM17, ADAM10 is the other well characterized ADAM protease responsible for HER ligand shedding. Therefore, we studied the role of ADAM10 in relation to trastuzumab treatment and resistance in HER2 positive breast cancer. ADAM10 expression was assessed in HER2 positive breast cancer cell lines and xenograft mice treated with trastuzumab. Trastuzumab treatment increased ADAM10 levels in HER2 positive breast cancer cells (p≤0.001 in BT474; p≤0.01 in SKBR3) and in vivo (p≤0.0001) compared to control, correlating with a decrease in PKB phosphorylation. ADAM10 inhibition or knockdown enhanced trastuzumab response in naïve and trastuzumab resistant breast cancer cells. Trastuzumab monotherapy upregulated ADAM10 (p≤0.05); and higher pre-treatment ADAM10 levels correlated with decreased clinical response (p≤0.05) at day 21 in HER2 positive breast cancer patients undergoing a trastuzumab treatment window study. Higher ADAM10 levels correlated with poorer relapse-free survival (p≤0.01) in a cohort of HER2 positive breast cancer patients. Our studies implicate a role of ADAM10 in acquired resistance to trastuzumab and establish ADAM10 as a therapeutic target and a potential biomarker for HER2 positive breast cancer patients.

    To study the relevance between cancer related fatigue and coping styles in breast cancer patients after chemotherapy. A survey was conducted in 396 patients with breast cancer after chemotherapy on cancer related fatigue scale and Jalowiec coping scale, and the relation was analyzed. The rate of overall fatigue in breast cancer patients was 96.97%, mostly moderate fatigue. The rate of fatigue dimensions from high to low was physical fatigue, feeling fatigue and cognitive fatigue, respectively. The score of coping styles in patients with breast cancer after chemotherapy from high to low was optimistic coping, facing bravely, support seeking, self-reliance, emotional catharsis, avoidance, fatalism, and conservation. The most widely used coping style was optimistic coping style, and the least was emotional catharisis. There was a positive correlation between coping style of emotional catharsis and cancer related fatigue of all dimensions (Pself-reliance, or conservation (P<0.05). There was also a negative correlation between physical fatigue and optimistic or support seeking (P<0.05), but there was a positive correlation between avoidance or fatalism and the dimensions of general fatigue, physical fatigue, and cognitive fatigue (P<0.05). There is prevalent cancer related fatigue in patients with breast cancer after chemotherapy. We should guide the patients to more active coping styles, to enhance the ability of psychological adaption in patients, reduce cancer related fatigue, and improve the quality of life.

    Full Text Available ABSTRACTBACKGROUNDNowadays cancer patients tend to be more involved in the medical decision process. Active participation improves health outcomes and patient satisfaction. To participate effectively patients require a huge amount of information, but time limits make it impossible to satisfy all information needs at clinics. We tried to find out which kind of media cancer patients use when searching for information and how often. Lastly, we try to find out how popular the Internet is in this regard.METODSIn this research we invited cancer patients, who had regular clinic examinations at the Oncology Institute between 21st and 25th May in 2012. We carried out a prospective research by anonymous questionnaires. We were investigating which media were used and how often. We analysed results with descriptive statistics, ANOVA, the χ²-Test and the t-test.RESULTS478 of 919 questionnaires distributed among cancer patients were returned. Mean age was 59.9 years. 61 % of responders were female, and the most common level of education was high school (33 %. Most common cancer type was breast cancer (33 %, followed by gastrointestinal and lung cancer. Patients search for information most often on television (81.4% responders, followed by specialized brochures (78%, internet (70.8% and newspapers (67.6%. Patients who do not use media for information searching are older than average (62.5 years vs. 59.9 years; p<0,000.CONCLUSIONSAccording to our results patients search for information most often on television, followed by brochures, internet and newspapers. Older patients less often search for information. This data might help doctors in everyday clinical practice.

    In the previous studies, using Pearson's product moment correlation coefficient, we found that in most cases of cancers, statistically significant positive correlations were observed between natural background radiation exposure rate and crude cancer mortality rate over the period 1950 - 1978. Furthermore, we found that the statistical significance of correlation between natural background radiation exposure rate and the age-adjusted cancer mortality rate in the same period mostly disappeared. We studied the cause of this apparent correlation and found that the prefecture with a higher natural background radiation exposure rate had a greater component ratio of older people. In Japan, a number of prefectures with a higher natural background exposure rate are located in relatively thinly populated districts which have been experiencing an outflow of the younger generation to more highly industrialized and urbanized areas. Therefore, statistically significant positive correlations were observed for almost all cancers between natural background radiation exposure rate and crude cancer mortality rate. In the present investigation, we statistically tested the frequency distributions of natural background radiation exposure rate and age-adjusted cancer mortality rate, and calculated Spearman's rank correlation coefficient between natural background radiation exposure rate and the age-adjusted cancer mortality rate. The frequency distribution of the natural background radiation exposure rate and that of the age-adjusted mortality rate appeared normal in most cases of cancer, and the statistical significance of correlation between natural background exposure rate and the age-adjusted cancer mortality rate did not differ much on the whole, even though we used Spearman's rank correlation coefficient between them.

    According to the recent worldwide estimation by the GLOBOCAN project, in total, 12.7 million new cancer cases and 7.6 million cancer deaths occurred in 2008. The worldwide number of cancer survivors within 5 years of diagnosis has been estimated at be almost 28.8 million. Informal caregivers, such as family members and close friends, provide essential support to cancer patients. The authors of this report provide an overview of issues in the study of informal caregivers for cancer patients and long-term survivors in the United States and Europe, characterizing the caregivers commonly studied; the resources currently available to them; and their unmet needs, their psychosocial outcomes, and the psychosocial interventions tailored to their special circumstances. A broad overview of the state of research and knowledge, both in Europe and the United States, and observations on the directions for future research are provided. PMID:23695928

    PurposeTo correlate prostate-specific antigen (PSA), free to total PSA percentage (fPSA%) and prostatic acid phosphatase (PAP) levels from peripheral and pelvic venous samples with prostatectomy specimens in patients with prostate adenocarcinoma and borderline elevation of PSA.Materials and MethodsIn this prospective institutional review board approved study, 7 patients with biopsy proven prostate cancer had a venous sampling procedure prior to prostatectomy (mean 3.2 days, range 1–7). Venous samples were taken from a peripheral vein (PVS), the right internal iliac vein, a deep right internal iliac vein branch, left internal iliac vein and a deep left internal iliac vein branch. Venous sampling results were compared to tumour volume, laterality, stage and grade in prostatectomy surgical specimens.ResultsMean PVS PSA was 4.29, range 2.3–6 ng/ml. PSA and PAP values in PVS did not differ significantly from internal iliac or deep internal iliac vein samples (p > 0.05). fPSA% was significantly higher in internal iliac (p = 0.004) and deep internal iliac (p = 0.003) vein samples compared to PVS. One of 7 patients had unilateral tumour only. This patient, with left–sided tumour, had a fPSA% of 6, 6, 6, 14 and 12 in his peripheral, right internal iliac, deep right internal iliac branch, left internal iliac and deep left internal iliac branch samples respectively. There were no adverse events.ConclusionfPSA%, unlike total PSA or PAP, is significantly higher in pelvic vein compared to peripheral vein samples when prostate cancer is present. Larger studies including patients with higher PSA values are warranted to further investigate this counterintuitive finding.

    To investigate the size criteria of multidetector computed tomography (MDCT) for the evaluation metastatic lymph nodes (LNs) for potentially operable squamous esophageal cancer, and to compare this information with the results of positron emission tomography-CT (PET-CT). Twenty-four patients who underwent radical esophagectomy for esophageal cancer were studied. All patients had preoperative MDCT and PET-CT. The MDCT findings were compared with those of PET-CT and were correlated with the surgical records. The receiver operating characteristic (ROC) curve method was used to determine the appropriate cut-off value to distinguish benign from metastatic LNs. The size of metastatic LNs (9.35 ± 3.41 mm) was significantly larger than that of benign LNs (5.74 ± 1.64 mm) (p<0.001). The best cut-off value was 7 mm (81.8% sensitivity, 80.8% specificity). PET-CT detected all metastatic LNs except for four in the peritumoral region. The sensitivity and specificity of metastatic LN evaluation on PET-CT were 82.6% and 99.4%, respectively. Only one LN without metastasis showed increased fluoro-2-deoxy-D-glucose uptake on PET-CT. Size of metastatic LNs can typically be < 10 mm. For MDCT, the short diameter of 7 mm may be the optimal criterion. PET-CT is very accurate for the assessment of metastatic LNs except for those in the peritumoral region

    To assess the needs of cancer patients for information about their condition and to understand the psychological impact of their illness. The discussion of prognosis and treatment options in the palliative setting is an important and difficult part of oncology practice. To evaluate this, we examined the experiences of cancer patients of the physical and psychological impact of their disease on their life, and their opinions on the communication of end-of-life decisions and treatment options. A patient questionnaire was designed that encompassed communication regarding treatment and prognosis, quality-of-life attitudes subsequent to cancer diagnosis, end-of-life care and cancer drug funding. One hundred and twenty-five patients with a diagnosis of cancer were asked to participate and 96 questionnaires were completed and available for analysis. The questionnaire consisted of 63 questions and was completed in both an inpatient and outpatient setting. This survey brought to light a number of controversial issues in cancer service provision, highlighting the emotional and psychological changes brought about by a cancer diagnosis. Major concerns of our patients include fear of death and pain, changes in interpersonal relationships and financial constraints. Only 66% of the patients wanted to be given a prognosis by their clinicians and just 70% of the patients recalled being given a detailed prognosis. 11% of the patients were not prepared to undergo palliative treatment. In all, 7% were not prepared to accept treatment for 1 year and 2% for 5 years of life in exchange for the potential side effects of cytotoxic chemotherapy. 12% of the patients would not want to be in possession of the information that they were in the terminal phase of the illness with a short time to live and 16% would not want this discussed with their next of kin. This study informs medical professionals about the importance of tailoring information to the needs of the individual patient, and we

    Breast cancer is one of the most common female malignant tumors. The occurrence and development of breast cancer are often accompanied by abnormal gene expression. It has been well accepted that estrogen receptor (ER), progesterone receptor (PR) and C-erbB-2 (epidermal growth factor receptor-2) are the main reference indexes for clinical endocrine therapy and prognosis prediction. Oncogene expression reflects the malignant biological behavior of breast cancer from different perspectives. Those aggressive behaviors cause a variety of changes in histopathology and thus in imaging. Therefore, the imaging features of breast cancer may indirectly demonstrate the status of ER, PR and C-erbB-2 to a certain extent. Until now, because of its simple operation,low cost and high accuracy, mammography is still the preferred method in breast cancer screening and diagnosis, and has been proposed as a noninvasive technique for prediction of the expression of ER, PR and C-erbB-2. It has potential clinical value in preoperative assessment and non-surgical treatment for those who are not able to perform immunohistochemistry. This review summarized previous related studies and explored mammography as a noninvasive predictor for ER, PR and C-erbB-2. (authors)

    The risk to develop colorectal and endometrial cancers among subjects testing positive for a pathogenic Lynch syndrome mutation varies, making the risk prediction difficult. Genetic risk modifiers alter the risk conferred by inherited Lynch syndrome mutations, and their identification can improve genetic counseling. We aimed at identifying rare genetic modifiers of the risk of Lynch syndrome endometrial cancer. A family based approach was used to assess the presence of genetic risk modifiers among 35 Lynch syndrome mutation carriers having either a poor clinical phenotype (early age of endometrial cancer diagnosis or multiple cancers) or a neutral clinical phenotype. Putative genetic risk modifiers were identified by Next Generation Sequencing among a panel of 154 genes involved in endometrial physiology and carcinogenesis. A simple pipeline, based on an allele frequency lower than 0.001 and on predicted non-conservative amino-acid substitutions returned 54 variants that were considered putative risk modifiers. The presence of two or more risk modifying variants in women carrying a pathogenic Lynch syndrome mutation was associated with a poor clinical phenotype. A gene-panel is proposed that comprehends genes that can carry variants with putative modifying effects on the risk of Lynch syndrome endometrial cancer. Validation in further studies is warranted before considering the possible use of this tool in genetic counseling.

    The present study was planned to explore the correlation between the methylation of APC (adenomatous polyposis coli) and colon carcinogenesis. Colon cancer tissues and tumor-adjacent normal tissues of 60 colon cancer patients (who received surgical operation in our hospital from January 2012 to December 2014) were collected. SW1116 cells in human colon cancer tissues were selected for culturing. 5-aza-2c-deoxycytidine (5-aza-dC) was utilized as an inhibitor of the methylation for APC gene. Methylation specific PCR (MSP) was utilized for detection of APC methylation in SW1116 cells. The MTT and Transwell assays were performed to detect the effect of the methylation of APC gene on the proliferation and invasive abilities of SW1116 cells. The correlation between the methylation of APC gene and pathological parameters of colon cancer patients was analyzed. MSP results revealed that 41 cases (68.33%) showed methylation of APC gene in colon cancer tissues. No methylation of APC gene was found in tumor-adjacent normal tissues. 5-aza-dC was able to inhibit the methylation of APC gene in SW1116 cells. APC gene methylation was correlated with tumor size, differentiation degree, lymph node metastasis and Dukes staging. In conclusion, the levels of the methylation of APC in colon cancer tissues and SW1116 cells are relatively high. The methylation of APC promoted the proliferation and invasion abilities of SW1116 cells. Furthermore, methylation is correlated with a variety of clinicopathological features of colon cancer patients.

  1. Psychological aspects of cancer patients

    Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.

    Full Text Available Cancer, which is one of the major health problems leading to despair, uncertainty, pain and suffering, is perceived as a serious and chronic disease. Cancer negatively affects individuals' quality of life due to the physical, psychological, and socio-economic problems. Today, despite inspiring advances in diagnosis and treatment of cancer and increase in survival rates of patients, appearance of physical and psycho-social disorders during cancer course disrupts the adaptation mechanisms of patients and undermines expectations for the future. Most of the time in clinical practice, clinicians focus on physical assessments and treatment planning of cancer patients primarily, ignoring social, psychological, economic and cultural factors related with the disease. This approach definitely influences patients' hope levels and their effective dealing with the disease. The aim of this article is to guide medical staff and increase awareness about the concept of hope in patients with cancer.

    Full Text Available Bacteremia remains a major cause of life-threatening complications in patients receiving anticancer chemotherapy. The spectrum and susceptibility profiles of causative microorganisms differ with time and place. Data from Lebanon are scarce. We aim at evaluating the epidemiology of bacteremia in cancer patients in a university hospital in Lebanon, emphasizing antibiotic resistance and risk factors of multi-drug resistant organism (MDRO-associated bacteremia.This is a retrospective study of 75 episodes of bacteremia occurring in febrile neutropenic patients admitted to the hematology-oncology unit at Makassed General Hospital, Lebanon, from October 2009-January 2012.It corresponds to epidemiological data on bacteremia episodes in febrile neutropenic cancer patients including antimicrobial resistance and identification of risk factors associated with third generation cephalosporin resistance (3GCR and MDRO-associated bacteremia. Out of 75 bacteremias, 42.7% were gram-positive (GP, and 57.3% were gram-negative (GN. GP bacteremias were mostly due to methicillin-resistant coagulase negative staphylococci (28% of total bacteremias and 66% of GP bacteremias. Among the GN bacteremias, Escherichia coli (22.7% of total, 39.5% of GN organisms and Klebsiellapneumoniae(13.3% of total, 23.3% of GN organisms were the most important causative agents. GN bacteremia due to 3GC sensitive (3GCS bacteria represented 28% of total bacteremias, while 29% were due to 3GCR bacteria and 9% were due to carbapenem-resistant organisms. There was a significant correlation between bacteremia with MDRO and subsequent intubation, sepsis and mortality. Among potential risk factors, only broad spectrum antibiotic intake >4 days before bacteremia was found to be statistically significant for acquisition of 3GCR bacteria. Using carbapenems or piperacillin/ tazobactam>4 days before bacteremia was significantly associated with the emergence of MDRO (p value<0.05.

    DNA ploidy pattern was shown to correlate with several clinicohistologic findings in several tumors. Aim of this study was to evaluate the correlation of the clinicohistologic findings in colorectal cancer and the failure pattern in rectosigmoid cancer with DNA ploidy. DNA flow cytometry using the Hedley methods on paraffin embedded specimen from 117 patients with colorectal cancers after curative resection was performed. We tried to find the correlation between DNA ploidy and various clinicohistologic findings. And then the correlation DNA ploidy and the failure pattern in 75 patients of rectosigmoid cancer was analized. Forty samples (34.2%) from tumors gave aneuploidy histogram. There was no significant difference in the frequency of DNA aneuploidy in terms of age, sex, depth of invasion, location and Dukes stage. But there was a significant correlation between DNA ploidy and the failure rates in Dukes stage B rectosigmoid cancer (p=0.048). These findings suggest that DNA ploidy pattern shows the correlation with the treatment failure rates in Dukes stage B rectosigmoid, but not with many other clinicohistologic findings. However, more patients will be needed to disclose these findings

    To evaluate the incidence of Poly Implant Prosthése (PIP) rupture as assessed by magnetic resonance imaging (MRI), the prevalence of the detected signs and the potential correlation with breast carcinoma. 67 patients with silicone breast implants and clinical indications for breast MRI were evaluated for a total of 125 implants: 40 (32%) PIP in 21 patients and 85 non-PIP in 46 patients (68%), the latest considered as control group. A 1.5-T MR imaging device was used in order to assess implant integrity with dedicated sequences and in 6 cases a dynamic study was performed for characterizing breast lesions. Two radiologists with more than 5 years' experience in the field of MRI evaluated in consensus all MR images searching for the presence of clear signs of intra or extra-capsular implant rupture. 20/40 (50%) PIP implants presented signs of intra-capsular rupture: linguine sign in 20 cases (100%), tear-drop sign in 6 (30%). In 12/20 cases (60%), MRI signs of extra-capsular rupture were detected. In the control group, an intra-capsular rupture was diagnosed in 12/85 cases (14%) associated with extra-capsular one in 5/12 cases (42%). Among the six cases with suspected breast lesions, in 2/21 patients with PIP implants (10%) a breast carcinoma was diagnosed (mucinous carcinoma, n=1; invasive ductal carcinoma, n=1). In 4/46 patients (9%) with non-PIP implants, an invasive ductal carcinoma was diagnosed. The rupture rate of PIP breast implants is significantly higher than non-PIP (50% vs 14%). MRI represents the most accurate imaging tool for evaluating breast prostheses and the linguine sign is the most common MRI sign to be searched. The incidence of breast carcinoma does not significantly differ between the PIP and non-PIP implants and a direct correlation with breast cancer can not been demonstrated.

    To compare the diagnostic performance of [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) and ultrasound imaging (US) with pathologic results obtained by US-guided biopsy and to evaluate the role of US in detecting internal mammary lymph node (LN) metastases in patients with breast cancer. Between January 2008 and December 2012, 37 patients with breast cancer (median age, 51.4 years; range, 40-79 years) underwent US-guided biopsy for suspected internal mammary LN metastases. Medical records, radiologic images, and reports were reviewed and correlated with pathologic results. The positive internal mammary LN metastasis rate was 78.4%. All biopsies were performed safely without major complications. Only 8.1% of obtained samples were unsatisfactory. There were statistically significant differences in lesion size (P = .0002), standardized uptake value on PET/CT (P = .0015), biopsy methods (P = .002), and specimen adequacy (P = .007) between metastatic and benign groups. Of the clinical factorsreviewed, only concurrent distant metastasis was correlated with internal mammary LN metastasis (P< .0001). Sensitivities for detecting internal mammary LN metastases were 76.7%, 96.7%, and 92.9% for initial US examinations, initial US combined with second-look US for initially missed cases, and PET/CT, respectively (P= .017). In a subgroup analysis, the only significant difference found was in sensitivities between initial and combined US (P = .019). In a receiver operating characteristic curve analysis, the area under the curve for PET/CT using standardized uptake criteria (0.87) was higher than that for US using size criteria (0.83); however, this difference was not significant. Although PET/CT is the best noninvasive method for evaluating internal mammary LN metastases, US is also useful if internal mammary LN evaluation is routine during standard US surveillance of patients with breast cancer. Additionally, US-guided biopsies could be

    Cancer in older people is a common problem worldwide. Among various types of cancer, skin cancers represent an important percentage. The principal risk factors are sun exposure, family history of skin cancer, fair skin color, but also the age plays an important role in the genesis of skin cancers. In older people there are a more prolonged exposure to carcinogenesis and a decreased functionality of reparation mechanisms of the cells so they acquire a selective advantage of growing and proliferating. At the same time age causes alteration in immune system by increasing NK-cells absolute number and decreasing both the endogenous and the lymphokine-induced lytic activities. The anti-tumor immune response is also mediated by the cytotoxic T- lymphocytes and in the elderly a strong reduction of T-cell function has been demonstrated. In elderly patients the diagnosis and the treatment of skin cancers can be different from younger counterpart. For example in older patients with melanoma is important to evaluate Breslow depth while higher mitotic rate has major value in younger patients. Moreover, the treatment should consider the performance status of patients and their compliance.

    Full Text Available To compare the apparent diffusion coefficient (ADC in lymph node metastases of non-small cell lung cancer (NSCLC patients with standardized uptake values (SUV derived from combined 18F-fluoro-deoxy-glucose-positron emission tomography/magnetic resonance imaging (18F-FDG PET/MRI.38 patients with histopathologically proven NSCLC (mean age 60.1 ± 9.5 y received whole-body PET/CT (Siemens mCT™ 60 min after injection of a mean dose of 280 ± 50 MBq 18F-FDG and subsequent PET/MRI (mean time after tracer injection: 139 ± 26 min, Siemens Biograph mMR. During PET acquisition, simultaneous diffusion-weighted imaging (DWI, b values: 0, 500, 1000 s/mm² was performed. A maximum of 10 lymph nodes per patient suspicious for malignancy were analyzed. Regions of interest (ROI were drawn covering the entire lymph node on the attenuation-corrected PET-image and the monoexponential ADC-map. According to histopathology or radiological follow-up, lymph nodes were classified as benign or malignant. Pearson's correlation coefficients were calculated for all lymph node metastases correlating SUVmax and SUVmean with ADCmean.A total of 146 suspicious lymph nodes were found in 25 patients. One hundred lymph nodes were eligible for final analysis. Ninety-one lymph nodes were classified as malignant and 9 as benign according to the reference standard. In malignant lesions, mean SUVmax was 9.1 ± 3.8 and mean SUVmean was 6.0 ± 2.5 while mean ADCmean was 877.0 ± 128.6 x10(-5 mm²/s in PET/MRI. For all malignant lymph nodes, a weak, inverse correlation between SUVmax and ADCmean as well as SUVmean and ADCmean (r = -0.30, p<0.05 and r = -0.36, p<0.05 existed.The present data show a weak inverse correlation between increased glucose-metabolism and cellularity in lymph node metastases of NSCLC patients. 18F-FDG-PET and DWI thus may offer complementary information for the evaluation of treatment response in lymph node metastases of NSCLC.

    What's known on the subject? and What does the study add? Increased sun exposure and blood levels of vitamin D have been postulated to be protective against prostate cancer. This is controversial. We investigated the relationship between prostate cancer incidence and solar radiation in non-urban Australia, and found a lower incidence in regions receiving more sunlight. In landmark ecological studies, prostate cancer mortality rates have been shown to be inversely related to ultraviolet radiation exposure. Investigators have hypothesised that ultraviolet radiation acts by increasing production of vitamin D, which inhibits prostate cancer cells in vitro. However, analyses of serum levels of vitamin D in men with prostate cancer have failed to support this hypothesis. This study has found an inverse correlation between solar radiation and prostate cancer incidence in Australia. Our population (previously unstudied) represents the third group to exhibit this correlation. Significantly, the demographics and climate of Australia differ markedly from those of previous studies conducted on men in the United Kingdom and the United States. • To ascertain if prostate cancer incidence rates correlate with solar radiation among non-urban populations of men in Australia. • Local government areas from each state and territory were selected using explicit criteria. Urban areas were excluded from analysis. • For each local government area, prostate cancer incidence rates and averaged long-term solar radiation were obtained. • The strength of the association between prostate cancer incidence and solar radiation was determined. • Among 70 local government areas of Australia, age-standardized prostate cancer incidence rates for the period 1998-2007 correlated inversely with daily solar radiation averaged over the last two decades. •  There exists an association between less solar radiation and higher prostate cancer incidence in Australia. © 2011 THE AUTHORS.

    2006-06-01

    This study analyzed the contact preferences of newly diagnosed cancer patients and healthy control group participants. In line with the theory of socioemotional selectivity, patients were more likely than control participants to prefer contact with familiar social partners, but this difference was stronger in younger and middle-aged patients than in older patients. Across a 6-month interval, patients' contact preferences changed according to the perceived success of therapy. For example, if therapy was perceived to be successful, patients showed an increasing interest in contacts with unfamiliar social partners. Results indicate that contact preferences are adapted to the perception of limited versus extended future lifetime. Copyright (c) 2006 APA, all rights reserved.

    Purpose: A head-to-head comparison of two clinical correlation models with a focus on geometrical accuracy for internal tumor motion estimation during real-time tumor tracking (RTTT). Methods and materials: Both the CyberKnife (CK) and the Vero systems perform RTTT with a correlation model that is able to describe hysteresis in the breathing motion. The CK dual-quadratic (DQ) model consists of two polynomial functions describing the trajectory of the tumor for inhale and exhale breathing motion, respectively. The Vero model is based on a two-dimensional (2D) function depending on position and speed of the external breathing signal to describe a closed-loop tumor trajectory. In this study, 20 s of internal motion data, using an 11 Hz (on average) full fluoroscopy (FF) sequence, was used for training of the CK and Vero models. Further, a subsampled set of 15 internal tumor positions (15p) equally spread over the different phases of the breathing motion was used for separate training of the CK DQ model. Also a linear model was trained using 15p and FF tumor motion data. Fifteen liver and lung cancer patients, treated on the Vero system with RTTT, were retrospectively evaluated comparing the CK FF, CK 15p and Vero FF models using an in-house developed simulator. The distance between estimated target position and the tumor position localized by X-ray imaging was measured in the beams-eye view (BEV) to calculate the 95th percentile BEV modeling errors (ME 95,BEV ). Additionally, the percentage of ME 95,BEV smaller than 5 mm (P 5mm ) was determined for all correlation models. Results: In general, no significant difference (p > 0.05, paired t-test) was found between the CK FF and Vero models. Based on patient-specific evaluation of the geometrical accuracy of the linear, CK DQ and Vero correlation models, no statistical necessity (p > 0.05, two-way ANOVA) of including hysteresis in correlation models was proven, although during inhale breathing motion, the linear model

    Objective: To investigate the correlation among MRI morphologic features, pathology, and molecular biology of breast cancer. Methods: MR scanning was performed in 78 patients with breast cancer before operation and MRI morphologic features of breast cancer were analyzed. The mastectomy specimens of the breast neoplasm were stained with immunohistochemistry, and the expression of estrogen receptor (ER), progesterone receptor (PR), C-erbB-2, p53, and the distribution of microvessel density (MVD) was measured. The pathologic results were compared with MRI features. Results: Among the 80 breast cancers, ER positive expression was positively correlated with the spiculate margin of breast cancer (P 0.05). Among the 41 breast cancers with dynamic MR scans, there was positive correlation between the spatial distribution of contrast agent and MVD (P<0.01). Conclusion: There exists some correlation among MRI morphologic features, pathology, and molecular biology factors in breast cancer to certain extent. The biologic behavior and prognosis of the breast cancer can be assessed according to MRI features

    The objective of this study was to calculate the dosimetry for thyroid remnants and other organs of 22 patients with differentiated thyroid cancer and compare the dosimetric results with the genetic effects that may occur due the introduction of ionizing radiation in the human body. The patients were divided in two groups: group A included the patients that went through the interruption of the thyroid hormone reposition and group B included the ones that received the recombinant human Thyroid Stimulating Hormone (rec-hTSH). Blood samples were collected at predetermined intervals and analyzed with the conventional chromosomal aberrations technique. Patients collected their own urine during 24 hours after the administration of the radioiodine. For internal dosimetry calculations it is being used MlRD methodology and software MIRDOSE-3 and MlRDOSE-OLINDA. Preliminary results of the absorbed dose of 12 patients (6 from each group) show the normal pattern of this type of absorption in treatment of thyroid remnants ablation with a mean effective dose of 3 3.2 {+-} 6.4 mSv/MBq (group A) and 15.0 {+-} 4.5 mSv/MBq (group B). In the cytogenetic results for 5 patients (4 from group A and 1 from group B), the microscopic analysis showed the presence of various types of chromosomal aberrations. The dicentric chromosome was the most frequently found and is considered the most sensitive indicator of radiation damage. The correlation between the absorbed dose and the cytogenetic dosimetry appears to be in good agreement so far, since the doses are consistent with the genetic damage found. (author)

    This study explored Iranian patients' experiences of cancer disclosure, paying particular attention to the ways of disclosure. Twenty cancer patients were invited to participate in this qualitative inquiry by research staff in the clinical setting. In-depth, semistructured interview data were analyzed through content analysis. The rigor of the study was established by principles of credibility, transferability, dependability, and confirmability. Four themes emerged: the atmosphere of non-disclosure, eventual disclosure, distress in knowing, and the desire for information. Non-disclosure was the norm for participants, and all individuals involved made efforts to maintain an atmosphere of non-disclosure. While a select few were informed of their diagnosis by a physician or another patient, the majority eventually became aware of their diagnosis indirectly by different ways. All participants experienced distress after disclosure. The participants wanted basic information about their prognosis and treatments from their treating physicians, but did not receive this information, and encountered difficulty accessing information elsewhere. These challenges highlight the need for changes in current medical practice in Iran, as well as patient and healthcare provider education. © 2012 Blackwell Publishing Asia Pty Ltd.

    To investigate the relationship between telomerase activity (TA) and matrix metallo proteinases 2 (MMP-2) on malignant behavior and prognosis predictable value in gastric cancer. Telomerase activity and MMP-2 protein expressions were tested in 40 gastric surgical resected cancer samples and the clinicopathological data of enrolled patients were obtained to get correlation analysis results. The expression of telomerase was up-regulated with infiltrating depth, lymph node metastasis and stage (P correlated with infiltrating depth (P < 0.05). Combined detections of telomerase activity and MMP2 protein could identify patients at high risk in disease recurrence and prognosis more efficiently.

    HER2 gene amplification or overexpression occurs in 15% to 25% of breast cancers and has implications for treatment and prognosis. The most commonly used methods for HER2 testing are fluorescence in situ hybridization (FISH) and immunohistochemistry. FISH is considered to be the reference standard and more accurately predicts response to trastuzumab, but is technically demanding, expensive, and requires specialized equipment. In situ hybridization is required to be eligible for adjuvant treatment with trastuzumab in Australia. Bright-field in situ hybridization is an alternative to FISH and uses a combination of in situ methodology and a peroxidase-mediated chromogenic substrate such as diaminobenzidine [chromogenic in situ hybridization (CISH)] or multimer technology coupled with enzyme metallography [silver-enhanced in situ hybridization (SISH)] to create a marker visible under bright-field microscopy. CISH was introduced into diagnostic testing in Australia in October 2006. SISH methodology is a more recent introduction into the testing repertoire. An evaluation of CISH and SISH performance to assess patient outcome were performed using tissue microarrays. Tissue microarrays were constructed in duplicate using material from 593 patients with invasive breast carcinoma and assessed using CISH and SISH. Gene amplification was assessed using the American Society of Clinical Oncology/College of American Pathologists guideline and Australian HER2 Advisory Board criteria (single probe: diploid, 1 to 2.5 copies/nucleus; polysomy >2.5 to 4 copies/nucleus; equivocal, >4 to 6 copies/nucleus; low-level amplification, >6 to 10 copies/nucleus and high-level amplification >10 copies/nucleus; dual probe HER2/CHR17 ratio: nonamplified 2.2). Results were informative for 337 tissue cores comprising 230 patient samples. Concordance rates were 96% for HER2 single probe CISH and SISH and 95.5% for single probe CISH and dual probe HER2/CHR17 SISH. Both bright-field methods correlated

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    Lung cancer is a leading cause of cancer deaths in the world. Cigarette smoking remains a prominent risk factor, but lung cancer incidence has been increasing in never smokers. Genetic abnormalities including epidermal growth factor receptor (EGFR) mutations predominate in never smoking lung cancer patients. Furthermore, familial aggregations of patients with these mutations reflect heritable susceptibility to lung cancer. The correlation between familial cancer history and EGFR mutations in never smokers with lung cancer requires investigation. This was a retrospective case-control study that evaluated the prevalence of EGFR mutations in lung cancer patients with familial cancer history. Never smokers with lung cancer treated at a hospital in Taiwan between April 2012 and May 2014 were evaluated. Inclusion criteria were never smokers with non-small cell lung cancer (NSCLC). Exclusion criteria involved patients without records of familial cancer history or tumor genotype. This study included 246 never smokers with lung cancer. The study population mainly involved never smoking women with a mean age of 60 years, and the predominant tumor histology was adenocarcinoma. Lung cancer patients with familial cancer history had an increased prevalence of EGFR mutations compared to patients without family history [odds ratio (OR): 5.9; 95% confidence interval (CI): 3.3-10.6; Pnon-pulmonary cancers (OR: 5.0; 95% CI: 2.5-10.0; Pnever smoking lung cancer patients with familial cancer history. Moreover, a sizable proportion of never smoking cancer patients harbored these mutations. These observations have implications for the treatment of lung cancer in never smokers.

    Objective: To study the correlation between the level of serum tumor makers and bone metastases of lung cancer. Method: In 128 diagnosed patients with lung cancer, small cell lung cancer were 26 cases, non-small cell lung cancer were 102 cases which included 44 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 4 cases of large cell carcinoma, 4 cases of squamous adenocarcinoma. "9"9"mTc-MDP whole-body bone scanning was performed in 128 patients with lung cancer. over the same period, the serum samples were collected in these patients and 30 comparison controls. CEA, CA125, CA199, SCC, NSE, CA15-3, and AFP were measured by ELISA technique. Bone imaging findings analysis used t-test, and serum levels of tumor markers analysis used χ"2 test. Results: The diagnostic of 53 cases of lung cancer with bone metastasis was subject to clinical criteria of lung cancer with bone metastases. The positive ratio of patients with osseous metastasis was confirmed by "9"9"mTc-MDP whole-body bone scanning was 23.44% (30/128), including 16 cases of lung adenocarcinoma, 9 cases of squamous cell carcinoma, 3 cases of small cell lung cancer , 1 case of large cell lung cancer, 1 case of squamous adenocarcinoma and multiple bone metastases accounted for 66.67% (20/30). The levels of serum CEA, CA125, CA199, SCC, NSE and CA15-3 were higher than the control group (P < O.05). 29 cases of CEA positive and 21 cases of CA125 positive were included in 30 cases of lung cancer with bone metastasis. There was a significant difference between the levels of CEA, CA125, CA199, NSE in lung cancer with bone metastases and without bone metastases (P < 0.05). The sensitivity of "9"9"mTc-MDP whole-body bone scanning in diagnosis of lung cancer with bone metastasis was 84.91%. Conclusion: The average value of CEA, CA125, and CA199, SCC, NSE and CA15-3 in lung cancer patients were significantly higher than the control group. In addition, there is a significantly correlation between the occurrence

    Highlights: • In non-triple negative breast cancer, metabolic parameter (SUVmax) was significantly correlated with perfusion parameters (Kep and Ve). • In triple negative cancers, any perfusion parameters did not correlated with metabolic parameters. • Higher SUVmax, higher SUVmax/Ktrans, higher MTV50/Ktrans, higher TLG50/Ktrans, higher TLG50/Ve ratios were significantly correlated with TNBC. • In triple negative breast cancer, perfusion and metabolic parameters are not significantly correlated. • Triple negative breast cancer showed higher metabolic–perfusion ratios compared to non-triple negative breast cancer. - Abstract: Objective: Our purpose was to evaluate whether breast cancer with high metabolic–perfusion ratio would be associated with poor histopathologic prognostic factors and whether triple negative breast cancer (TNBC) would show high metabolic–perfusion ratio compared to non-triple negative breast cancer (non-TNBC). Methods: From March 2011 to November 2011, 67 females with invasive ductal carcinoma of breast who underwent both MRI and 18F-FDG PET/CT were included. Perfusion parameters including Ktrans, Kep and Ve were acquired from Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Metabolic parameters including the standardized uptake value (SUV) and volumetric metabolic parameters including metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were obtained from F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Results: In non-TNBC, SUVmax was significantly correlated with Kep (ρ = 0.298, p = 0.036) and Ve (ρ = −0.286, p = 0.044). In TNBC, there was no significant correlation between all perfusion and metabolic parameters. Compared to non-TNBC, higher SUVmax (10.2 vs 5.3, p < 0.001), higher SUVmax/Ktrans (56.02 vs 20.3, p < 0.001), higher MTV50/Ktrans (7.8 vs 16.54, p < 0.001), higher TLG50/Ktrans (36.49 vs 12.3, p < 0.001), higher TLG50/Ve (91.34 vs 27.1 p = 0.022) were

    Liquid biopsy is an alternative to tissue for RAS testing in metastatic colorectal carcinoma (mCRC) patients. Little information is available on the predictive role of liquid biopsy RAS testing in patients treated with first-line anti-EGFR monoclonal antibody-based therapy. In the CAPRI-GOIM trial, 340 KRAS exon-2 wild-type mCRC patients received first-line cetuximab plus FOLFIRI. Tumor samples were retrospectively assessed by next generation sequencing (NGS). Baseline plasma samples were analyzed for KRAS and NRAS mutations using beads, emulsion, amplification, and magnetics digital PCR (BEAMing). Discordant cases were solved by droplet digital PCR (ddPCR) or deep-sequencing. A subgroup of 92 patients with available both NGS data on tumor samples and baseline plasma samples were included in this study. Both NGS analysis of tumor tissue and plasma testing with BEAMing identified RAS mutations in 33/92 patients (35.9%). However, 10 cases were RAS tissue mutant and plasma wild-type, and additional 10 cases were tissue wild-type and plasma mutant, resulting in a concordance rate of 78.3%. Analysis of plasma samples with ddPCR detected RAS mutations in 2/10 tissue mutant, plasma wild-type patients. In contrast, in all tissue wild-type and plasma mutant cases, ddPCR or deep-sequencing analysis of tumor tissue confirmed the presence of RAS mutations at allelic frequencies ranging between 0.15% and 1.15%. The median progression-free survival of RAS mutant and wild-type patients according to tissue (7.9 versus 12.6 months; P = 0.004) and liquid biopsy testing (7.8 versus 13.8 moths; P < 0.001) were comparable. Similar findings were observed for the median overall survival of RAS mutant and wild-type patients based on tissue (22.1 versus 35.8 months; P = 0.016) and plasma (19.9 versus 35.8 months; P = 0.013) analysis. This study indicates that RAS testing of liquid biopsy results in a similar outcome when compared with tissue testing in mCRC patients

    Breast cancer is the most frequent cancer in women globally and represents the second leading cause of cancer death among women (after lung cancer). India is going through epidemiologic transition. It is reported that the incidence of breast cancer is rising rapidly as a result of changes in reproductive risk factors, dietary habits and increasing life expectancy, acting in concert with genetic factors. In order to understand the existing epidemiological correlates of breast cancer in South India, a systematic review of evidence available on epidemiologic correlates of breast cancer addressing incidence, prevalence, and associated factors like age, reproductive factors, cultural and religious factors was performed with specific focus on screening procedures in southern India. An increase in breast cancer incidence due to various modifiable risk factors was noted, especially in women over 40 years of age, with late stage of presentation, lack of awareness about screening, costs, fear and stigma associated with the disease serving as major barriers for early presentation. Educational strategies should be aimed at modifying the life style, early planning of pregnancy, promoting breast feeding and physical activity. It is very important to obtain reliable data for planning policies, decision-making and setting up the priorities.

    Purpose: To review the impact of anemia/tumor hypoxemia on the quality of life and survival in cancer patients, and to assess the problems associated with the correction of this difficulty. Methods: MEDLINE searches were performed to find relevant literature regarding anemia and/or tumor hypoxia in cancer patients. Articles were evaluated in order to assess the epidemiology, adverse patient effects, anemia correction guidelines, and mechanisms of hypoxia-induced cancer cell growth and/or therapeutic resistance. Past and current clinical studies of radiosensitization via tumor oxygenation/hypoxic cell sensitization were reviewed. All clinical studies using multi-variate analysis were analyzed to show whether or not anemia and/or tumor hypoxemia affected tumor control and patient survival. Articles dealing with the correction of anemia via transfusion and/or erythropoietin were reviewed in order to show the impact of the rectification on the quality of life and survival of cancer patients. Results: Approximately 40-64% of patients presenting for cancer therapy are anemic. The rate of anemia rises with the use of chemotherapy, radiotherapy, and hormonal therapy for prostate cancer. Anemia is associated with reductions both in quality of life and survival. Tumor hypoxemia has been hypothesized to lead to tumor growth and resistance to therapy because it leads to angiogenesis, genetic mutations, resistance to apoptosis, and a resistance to free radicals from chemotherapy and radiotherapy. Nineteen clinical studies of anemia and eight clinical studies of tumor hypoxemia were found that used multi-variate analysis to determine the effect of these conditions on the local control and/or survival of cancer patients. Despite differing definitions of anemia and hypoxemia, all studies have shown a correlation between low hemoglobin levels and/or higher amounts of tumor hypoxia with poorer prognosis.

    The study was designed to evaluate 1) the relationship between PET image textural features (TFs) and SUVs, metabolic tumour volume (MTV), total lesion glycolysis (TLG) and tumour characteristics in a large prospective and homogenous cohort of oestrogen receptor-positive (ER+) breast cancer (BC) patients, and 2) the capability of those parameters to predict response to neoadjuvant chemotherapy (NAC). 171 consecutive patients with large or locally advanced ER+ BC without distant metastases underwent an {sup 18}F-FDG PET examination before NAC. The primary tumour was delineated with an adaptive threshold segmentation method. Parameters of volume, intensity and texture (entropy, homogeneity, contrast and energy) were measured and compared with tumour characteristics determined on pre-treatment breast biopsy (Wilcoxon rank-sum test). The correlation between PET-derived parameters was determined using Spearman's coefficient. The relationship between PET features and pathological findings was determined using the Wilcoxon rank-sum test. Spearman's coefficients between SUV{sub max} and TFs were 0.43, 0.24, -0.43 and -0.15 respectively for entropy, homogeneity, energy and contrast; they were higher between MTV and TFs: 0.99, 0.86, -0.99 and -0.87. All TFs showed a significant association with the histological type (IDC vs. ILC; 0.02 < P < 0.03) but didn't with immunohistochemical characteristics. SUV{sub max} and TLG predicted the pathological response (P = 0.0021 and P = 0.02 respectively); TFs didn't (P: 0.27, 0.19, 0.94, 0.19 respectively for entropy, homogeneity, energy and contrast). The correlation of TFs was poor with SUV parameters and high with MTV. TFs showed a significant association with the histological type. Finally, while SUV{sub max} and TLG were able to predict response to NAC, TFs failed. (orig.)

    Nuclear receptor coactivator 5 (NCOA5) is known to modulate ERα-mediated transcription and has been found to be involved in the progression of several malignancies. However, the potential correlation between NCOA5 and clinical outcome in patients with luminal breast cancer remains unknown. In the present study, we demonstrated that NCOA5 was significantly up-regulated in luminal breast cancer tissues compared with adjacent non-cancerous tissues both in validated cohort and TCGA cohort. Moreover, Kaplan-Meier analysis indicated that patients with high NOCA5 expression had significantly lower overall survival (P = 0.021). Cox regression analysis indicated that the high NOCA5 expression was independent high risk factor as well as old age (>60) and HER-2 expression (P = 0.039; P = 0.003; P = 0.005; respectively). This study provides new insights and evidences that NOCA5 over-expression was significantly correlated with progression and prognosis in luminal breast cancer. However, the precise cellular mechanisms for NOCA5 in luminal breast cancer need to be further explored. - Highlights: • NCOA5 is significantly over-expressed in human luminal breast cancer tissues. • NOCA5 was involved in the progression of luminal breast cancer. • NCOA5 can predict the progression of luminal breast cancer.

    Full Text Available Context: Fear of cancer recurrence (FOCR is one of the most important psychological problems among cancer patients. In extensive review of related literature there were no articles on FOCR among Iranian cancer patients. Aim: The aim of present study was to investigation FOCR and its predictive factors among Iranian cancer patients. Materials and Methods: In this descriptive-correlational study 129 cancer patients participated. For data collection, the demographic checklist and short form of fear of progression questionnaire was used. Logistic regression was used to determine predictive factors of FOCR. Result: Mean score of FOCR among participants was 44.8 and about 50% of them had high level of FOCR. The most important worries of participants were about their family and the future of their children and their lesser worries were about the physical symptoms and fear of physical damage because of cancer treatments. Also, women, breast cancer patient, and patients with lower level of education have more FOCR. Discussion: There is immediate need for supportive care program designed for Iranian cancer patients aimed at decreasing their FOCR. Especially, breast cancer patients and the patient with low educational level need more attention.

    Full Text Available Context Capecitabine, an oral drug, is as effective as traditional chemotherapy drugs. Objectives To investigate the adhesion to treatment with oral capecitabine in breast and colorectal cancer, and to determine any correlation with changes in patient’s quality of life. Methods Patients with colorectal cancer or breast cancer using capecitabine were included. The patients were asked to bring any medication left at the time of scheduled visits. The QLQ-C30 questionnaire was applied at the first visit and 8-12 weeks after treatment. Results Thirty patients were evaluated. Adherence was 88.3% for metastatic colon cancer, 90.4% for non-metastatic colon cancer, 94.3% for rectal cancer and 96.2% for metastatic breast cancer. No strong correlation between adherence and European Organisation for Research and Treatment of Cancer QLQ-C30 functional or symptom scale rates had been found. There was no statistically significant correlation between compliance and the functional and symptom scales of the questionnaire before and after chemotherapy, with the exception of dyspnea. Conclusions Although no absolute adherence to oral capecitabine treatment had been observed, the level of adherence was good. Health professionals therefore need a greater focus in the monitoring the involvement of patients with oral treatment regimens. Patients with lesser degrees of dyspnea had greater compliance.

    Eliciting antitumor T-cell response by targeting the PD-1/PD-L1 axis with checkpoint inhibitors has emerged as a novel therapeutic strategy in non-small cell lung cancer (NSCLC). The identification of predictors for sensitivity or resistance to these agents is, therefore, needed. Herein, we investigate the correlation of metabolic information on FDG-PET with tissue expression of immune-checkpoints and other markers of tumor-related immunity in resected NSCLC patients. All patients referred to our institution for upfront surgical resection of NSCLC, who were investigated with FDG-PET prior to surgery, were consecutively included in the study. From January 2010 to May 2014, 55 patients (stage IA-IIIB; M:F = 42:13; mean age 68.9 years) were investigated. Sampled surgical tumor specimens were analyzed by immunohistochemistry (IHC) for CD68-TAMs (tumor-associated macrophages), CD8-TILs (tumor infiltrating lymphocytes), PD-1-TILs, and PD-L1 tumor expression. Immunoreactivity was evaluated, and scores were compared with imaging findings. FDG-PET images were analyzed to define semi-quantitative parameters: SUVmax and SUVmean. Metabolic information on FDG-PET was correlated with tissue markers expression and disease-free survival (DFS) considering a median follow-up of 16.2 months. Thirty-six adenocarcinomas (ADC), 18 squamous cell carcinomas (SCC), and one sarcomatoid carcinoma were analyzed. All tumors resulted positive at FDG-PET: median SUVmax 11.3 (range: 2.3-32.5) and SUVmean 6.4 (range: 1.5-13) both resulted significantly higher in SCC compared to other NSCLC histotypes (p = 0.007 and 0.048, respectively). IHC demonstrated a median immunoreactive surface covered by CD68-TAMs of 5.41 % (range: 0.84-14.01 %), CD8-TILs of 2.9 % (range: 0.11-11.92 %), PD-1 of 0.65 % (range: 0.02-5.87 %), and PD-L1 of 0.7 % (range: 0.03-10.29 %). We found a statistically significant correlation between SUVmax and SUVmean with the expression of CD8 TILs (rho = 0.31; p = 0.027) and PD-1

All tumors resulted positive at FDG-PET: median SUVmax 11.3 (range: 2.3-32.5) and SUVmean 6.4 (range: 1.5-13) both resulted significantly higher in SCC compared to other NSCLC histotypes (p = 0.007 and 0.048, respectively). IHC demonstrated a median immunoreactive surface covered by CD68-TAMs of 5.41 % (range: 0.84-14.01 %), CD8-TILs of 2.9 % (range: 0.11-11.92 %), PD-1 of 0.65 % (range: 0.02-5.87 %), and PD-L1 of 0.7 % (range: 0.03-10.29 %). We found a statistically significant correlation between SUVmax and SUVmean with the expression of CD8 TILs (rho = 0.31; p = 0.027) and PD-1

    The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care. It threatens not only the outcome and quality of life of cancer patients but also the success of oncologic treatments which often demand high input of human and financial resources. Meanwhile application of nutritional therapy is legally regulated in Hungary and a very recent update of the European guideline on cancer patient nutrition published in 2017 is available. Moreover, cost effectiveness of nutritional therapy has been proven in a number of studies. In this review we present the basics of nutritional therapy including nutritional screening and evaluation, nutritional plan, the role of nutrition support teams, oral, enteral and parenteral nutrition, the use of different drugs and special nutrients and the follow-up of the patients.

    The Institute of Medicine has called for more coordinated cancer care models that correspond to initiatives led by cancer providers and professional organizations. These initiatives parallel those underway to integrate the management of patients with chronic conditions. We developed 5 breast cancer patient and practice management process measures based on the Chronic Care Model. We then performed a survey to evaluate patterns and correlates of these measures among attending surgeons of a population-based sample of patients diagnosed with breast cancer between June 2005 and February 2007 in Los Angeles and Detroit (N = 312; response rate, 75.9%). Surgeon practice specialization varied markedly with about half of the surgeons devoting 15% or less of their total practice to breast cancer, whereas 16.2% of surgeons devoted 50% or more. There was also large variation in the extent of the use of patient and practice management processes with most surgeons reporting low use. Patient and practice management process measures were positively associated with greater levels of surgeon specialization and the presence of a teaching program. Cancer program status was weakly associated with patient and practice management processes. Low uptake of patient and practice management processes among surgeons who treat breast cancer patients may indicate that surgeons are not convinced that these processes matter, or that there are logistical and cost barriers to implementation. More research is needed to understand how large variations in patient and practice management processes might affect the quality of care for patients with breast cancer.

    Keratinocyte growth factor (KGF) is reported to be implicated in the growth of some cancer cells. Matrix metalloproteinase 9 (MMP-9) is thought to enhance the tumor invasion and metastasis ability. This study was aimed at analyzing the relationship between KGF and MMP-9 expression and patients' clinicopathological characteristics to clarify the clinical significance of the expression of KGF and MMP-9 in gastric cancer. Tissue samples from 161 patients with primary gastric cancer were investigated using immunohistochemistry. The relationship between KGF and/or MMP-9 expression and clinicopathological characteristics was analyzed. KGF expression and MMP-9 expression in gastric cancer tissue were observed in 62 cases (38.5%) and 97 cases (60.2%), respectively. MMP-9 was significantly associated with depth of invasion, lymph node metastasis and TNM stage. The prognosis of MMP-9-positive patients was significantly poorer than that of MMP-9-negative patients (p = 0.009). KGF expression was positively correlated with MMP-9 expression in gastric cancer, and the prognosis of patients with both KGF- and MMP-9-positive tumors was significantly worse than that of patients with negative tumors for either factor (p = 0.045). Expression of MMP-9 was revealed to be an independent prognostic factor (p = 0.026). Coexpression of KGF and MMP-9 in gastric cancer could be a useful prognostic factor, and MMP-9 might also serve as a novel target for both prognostic prediction and therapeutics.

    Aim: Recent protein expression profiling of breast cancer has identified specific subtypes with clinical, biological, and therapeutic implications. The aim of this study was to identify the mammographic correlates of these novel molecular classes of invasive breast cancer. Materials and methods: The mammographic findings of 415 patients with operable breast cancer were correlated with the previously described protein expression classes identified by our group using immunohistochemical (IHC) assessment of a large series of breast cancer cases prepared as tissue microarrays (TMAs). Twenty-five proteins of known relevance in breast cancer were assessed, including hormone receptors, HER-2 status, basal and luminal markers, p53 expression, and E-cadherin. Results: The mammographic background pattern and proportion of lesions that were mammographically occult were similar in all groups. Groups characterized by luminal and hormone receptor positivity had significantly more spiculate lesions at mammography. Groups characterized by HER-2 overexpression, basal characteristics, and E-cadherin positivity had a significantly higher proportion of ill-defined masses. These findings were independent of histological grade. Conclusion: The mammographic features of breast cancer show significant correlation with molecular classes of invasive breast cancer identified by protein expression IHC analysis. The biological reasons for the findings and implications of these regarding imaging protocols require further study and may provide mechanisms for improvement of detection of these lesions.

    Full Text Available Abstract Background Epigenetic gene silencing is one of the major causes of carcinogenesis. Its widespread occurrence in cancer genome could inactivate many cellular pathways including DNA repair, cell cycle control, apoptosis, cell adherence, and detoxification. The abnormal promoter methylation might be a potential molecular marker for cancer management. Methods For rapid identification of potential targets for aberrant methylation in gynecological cancers, methylation status of the CpG islands of 34 genes was determined using pooled DNA approach and methylation-specific PCR. Pooled DNA mixture from each cancer type (50 cervical cancers, 50 endometrial cancers and 50 ovarian cancers was made to form three test samples. The corresponding normal DNA from the patients of each cancer type was also pooled to form the other three control samples. Methylated alleles detected in tumors, but not in normal controls, were indicative of aberrant methylation in tumors. Having identified potential markers, frequencies of methylation were further analyzed in individual samples. Markers identified are used to correlate with clinico-pathological data of tumors using χ2 or Fisher's exact test. Results APC and p16 were hypermethylated across the three cancers. MINT31 and PTEN were hypermethylated in cervical and ovarian cancers. Specific methylation was found in cervical cancer (including CDH1, DAPK, MGMT and MINT2, endometrial cancer (CASP8, CDH13, hMLH1 and p73, and ovarian cancer (BRCA1, p14, p15, RIZ1 and TMS1.

    Acute kidney injury (AKI) is a frequent and significant complication of cancer and cancer therapy. Cancer patients frequently encounter risk factors for AKI including older age, CKD, prerenal conditions, sepsis, exposure to nephrotoxins, and obstructive physiology. AKI can also be secondary to paraneoplastic conditions, including glomerulonephritis and microangiopathic processes. This complication can have significant consequences, including effects on patients' ability to continue to receive therapy for their malignancy. This review will serve to summarize potential etiologies of AKI that present in patients with cancer as well as to highlight specific patient populations, such as the critically ill cancer patient.

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications

    Full text: Radiosensitivity of peripheral blood lymphocytes from prostate cancer patients is being investigated using the G2 assay and the Cytokinesis Block Micronucleus(CBMN)assay. The G2 assay evaluates chromosomal damage caused by irradiating cells in the G2 phase of the cell cycle. The CBMN assay quantifies the post mitotic micronuclei, which are the expression of damage incurred during G0. An association between hypersensitivity to the chromosome damaging effects of ionising radiation and cancer predispostion has been demonstrated in a number of heritable conditions by using the aforementioned techniques. Recently, increased chromosomal radiosensitivity has been demonstrated in a significant proportion of patients with no obvious family history of malignancy. The aim of this study is to establish whether a group of prostatic carcinoma patients exists and if so whether there are any correlations between their G2 and G0 sensitivities. The study has shown there is no correlation between G2 and G0 sensitivity, confirming the general trend that individuals exhibiting chromosomal radiosensitivity are defective in only one mechanism and G2 and G0 sensitivity are largely independent. Current data indicates that there is an identifiable group of men within the prostate cancer population with increased chromosomal radiosensitivity. Using the G2 assay and the 90th percentile of the controls as a cut off point for sensitivity, no significant difference between the controls and the patient population has been found. However, using the CBMN assay and again the 90th percentile, approximately 11% of the control group are sensitive compared with approximately 40% of the carcinoma cases. The implications of this increased radiosensitivity are as yet unclear, but it is indicative of increased chromosomal fragility and therefore, possibly associated with malignant transformation. Hence, it may prove a useful tool in identifying individuals at increased risk of developing

    Age differences are not evident in pain-related stoicism and cautiousness in people with cancer pain. Little is known about the factors associated with these pain-related attitudes or age-related patterns in these associations. The present cross-sectional study investigated the biopsychosocial correlates of the attitudes in younger and older patients with advanced cancer. Pain-related stoicism (fortitude, concealment, superiority) and cautiousness (self-doubt, reluctance) were assessed using the Pain Attitudes Questionnaire-Revised (PAQ-R). Participants, 155 younger (younger than 60 years old) and 114 older (60 years old or older) patients with advanced cancer completed the PAQ-R and measures of sociodemographic and medical characteristics, pain intensity, cognitive-affective pain-related responses, physical functioning, psychological distress and well-being, and psychosocial functioning. Backwards regression analyses identified correlates for each PAQ-R factor separately for younger and older patients. Activity engagement was a frequent correlate, but its relationship with concealment was the only association common to both age groups. Younger and older patients exhibited different avoidance-related constructs suggesting relational challenges in the former group (avoidant attachment) and intrapersonal fear in the latter (cognitive avoidance). Medical correlates also showed age differences: younger patients showed symptom-focused correlates, whereas older patients showed aging-related correlates. Findings support a biopsychosocial framework of cancer-pain adaptation incorporating a lifespan-developmental perspective. To our knowledge, this article is the first to identify biopsychosocial correlates of stoic and cautious attitudes toward cancer pain in younger and older patients with advanced cancer. Findings highlight possible age-related motivations for greater pain-related stoicism or cautiousness and can potentially inform interventions addressing challenges in

    Patients with stage IIIa lung cancer have improved survival following surgery. The authors reviewed the CT, surgical, and pathologic findings in 26 patients with completely resected stage IIIa lung cancer. These include examples of the different subsets of stage IIIa disease. CT correctly predicted chest-wall invasion in only two of ten patients, pericardial involvement in one of three, and tumor extension to within 2 cm of the carina in one of three patients. It detected mediastinal nodal disease in eight of 11 patients. CT is of limited value in assessing chest-wall or pericardial extension; however, such extension does not preclude complete resection. Ipsilateral nodal involvement also doses not preclude surgery

    To evaluate whether apparent diffusion coefficient (ADC) value of gastric cancer obtained from diffusion weighted imaging (DWI) correlates with the HER2 status. Forty-five patients, who had been diagnosed with gastric cancer through biopsy, were enrolled in this IRB-approved study. Each patient underwent a DWI (b values: 0 and 1,000 sec/mm 2 ) prior to surgery (curative gastrectomy or palliative resection). Postoperative microscopic findings, HER2 status by immunohistochemical analysis and fluorescence in situ hybridization (FISH) were obtained. HER2 status was compared among gastric cancers with various histopathological features using the chi square test. The ADC values of gastric cancers with positive and negative HER2 were compared using the student t test. A weak yet significant correlation was observed between the mean ADC values and HER2 status (r = 0.312, P = 0.037) and scores (r = 0.419, P = 0.004). The mean ADC value of HER2-positive gastric cancers was significantly higher than those of HER2-negative tumors (1.211 vs. 0.984 mm 2 /s, P = 0.020). The minimal ADC value of HER2-positive gastric cancers was significantly higher than those of HER2-negative tumors (1.105 vs. 0.905 × 10 −3 mm 2 /s, P = 0.036). In this pilot study, we have demonstrated that the ADC values of gastric cancer correlate with the HER2 status. Future research is warranted to see if DWI can predict HER2 status and help in tailoring therapy for gastric cancer

    To find out any correlation between dynamic contrast-enhanced (DCE) model-based parameters and model-free parameters, and evaluate correlations between perfusion parameters with histologic prognostic factors. Model-based parameters (Ktrans, Kep and Ve) of 102 invasive ductal carcinomas were obtained using DCE-MRI and post-processing software. Correlations between model-based and model-free parameters and between perfusion parameters and histologic prognostic factors were analysed. Mean Kep was significantly higher in cancers showing initial rapid enhancement (P = 0.002) and a delayed washout pattern (P = 0.001). Ve was significantly lower in cancers showing a delayed washout pattern (P = 0.015). Kep significantly correlated with time to peak enhancement (TTP) (ρ = -0.33, P < 0.001) and washout slope (ρ = 0.39, P = 0.002). Ve was significantly correlated with TTP (ρ = 0.33, P = 0.002). Mean Kep was higher in tumours with high nuclear grade (P = 0.017). Mean Ve was lower in tumours with high histologic grade (P = 0.005) and in tumours with negative oestrogen receptor status (P = 0.047). TTP was shorter in tumours with negative oestrogen receptor status (P = 0.037). We could acquire general information about the tumour vascular physiology, interstitial space volume and pathologic prognostic factors by analyzing time-signal intensity curve without a complicated acquisition process for the model-based parameters.

    Full Text Available Carcinoembryonic antigen (CEA–targeted imaging and therapeutic agents are being tested in clinical trials. If CEA overexpression in malignant tissue corresponds with elevated serum CEA, serum CEA could assist in selecting patients who may benefit from CEA-targeted agents. This study aims to assess the relationship between serum CEA and CEA expression in pancreatic (n = 20 and rectal cancer tissues (n = 35 using histopathology. According to local laboratory standards, a serum CEA >3 ng/mL was considered elevated. In pancreatic cancer patients a significant correlation between serum CEA and percentage of CEA-expressing tumor cells was observed ( P  = .04, ρ = .47. All 6 patients with homogeneous CEA expression in the tumor had a serum CEA >3 ng/mL. Most rectal cancer tissues (32/35 showed homogeneous CEA expression, independent of serum CEA levels. This study suggests that selection of pancreatic cancer patients for CEA-targeted agents via serum CEA appears adequate. For selection of rectal cancer patients, serum CEA levels are not informative.

    Full Text Available Detection of cancer is often equal to facing with a crisis by the patients. Traditionally it is believed that cancer diagnosis should not be told to the patients. The aim of this study was to compare the attitudes towards the disclosure of cancer diagnosis in patients with cancer and control group included healthy people. This crosssectional study was carried out in 2015 with a total of 531 people. We used three questionnaires to collect data. The first one was EORTC QLQ-C30 to assess quality of life of patients with cancer. The second one included items to assess the patients' willingness for detection of the cancer diagnosis. Finally, the third one was the DUREL to evaluate religiosity. Five hundred and thirty one subjects including 216 patients with cancer and 315 healthy people were studied. Mean age of participants was 44 ± 15.7, 50.5% were female. Overall, 63% of patien ts with cancer were informed of their disease status and 37% uninformed. A significant association was seen between the awareness of cancer with physical and social functioning of quality of life. There was a positive significant association between the tendency for being informed of the diagnosis and non-organizational religious activity in participants without cancer. Global health status and all dimensions of religious were correlated in patients significantly. We found the majority of subjects tend to be aware of the disclosure of diagnosis. The physical and social functioning of quality of life were better in uninformed patients than informed patients.

    Full Text Available Abstract Background Medical oncologists continue to use performance status as a proxy for quality of life (QOL measures, as completion of QOL instruments is perceived as time consuming, may measure aspects of QOL not affected by cancer therapy, and interpretation may be unclear. The pulse oximeter is widely used in clinical practice to predict cardiopulmonary morbidity after lung resection in cancer patients, but little is known on its role outside the surgical setting. We evaluated whether the Lung Cancer Symptom Scale and pulse oximetry may contribute to the evaluation of lung cancer patients who received standard anticancer therapy. Methods We enrolled forty-one consecutive, newly diagnosed, patients with locally advanced or metastatic lung cancer in this study. We developed a survival model with the variables gender, age, histology, clinical stage, Karnofsky performance status, wasting, LCSS symptom scores, average symptom burden index, and pulse oximetry (SpO2. Results Patient and observer-rated scores were correlated, except for the fatigue subscale. The median SpO2 was 95% (range: 86 to 98, was unrelated to symptom scores, and was weakly correlated with observer cough scores. In a multivariate survival model, SpO2 > 90% and patient scores on the LCSS appetite and fatigue subscales were independent predictors of survival. Conclusion LCSS fatigue and appetite rating, and pulse oximetry should be studied further as prognostic factors in lung cancer patients.

    Axillary ultrasound has been adopted for preoperative planning in breast cancer. Our objective was to determine features predictive of abnormal AUS and/or positive axillary node needle biopsy (NBx). Single-institution database of breast cancer patients identified patients with preoperative AUS. Patient characteristics and outcomes were correlated with AUS and NBx. Significant features were identified using univariable and multivariable analysis and correlative statistics. Three hundred thirteen breast cancers were evaluated. Abnormal AUS was demonstrated in 250 cases (80%). Node needle biopsy was performed in 247 cases (79%). Sensitivity and specificity was 93% and 48% for AUS and 86% and 100% for NBx, respectively. Palpable axillary adenopathy was significant in logistic regression model (P AUS and NBx (P AUS. Copyright © 2012 Elsevier Inc. All rights reserved.

    To determine whether large rectal volume on planning computed tomography (CT) results in lower tumor regression grade (TRG) after neoadjuvant concurrent chemoradiotherapy (CCRT) in rectal cancer patients. We reviewed medical records of 113 patients treated with surgery following neoadjuvant CCRT for rectal cancer between January and December 2012. Rectal volume was contoured on axial images in which gross tumor volume was included. Average axial rectal area (ARA) was defined as rectal volume divided by longitudinal tumor length. The impact of rectal volume and ARA on TRG was assessed. Average rectal volume and ARA were 11.3 mL and 2.9 cm². After completion of neoadjuvant CCRT in 113 patients, pathologic results revealed total regression (TRG 4) in 28 patients (25%), good regression (TRG 3) in 25 patients (22%), moderate regression (TRG 2) in 34 patients (30%), minor regression (TRG 1) in 24 patients (21%), and no regression (TRG0) in 2 patients (2%). No difference of rectal volume and ARA was found between each TRG groups. Linear correlation existed between rectal volume and TRG (p = 0.036) but not between ARA and TRG (p = 0.058). Rectal volume on planning CT has no significance on TRG in patients receiving neoadjuvant CCRT for rectal cancer. These results indicate that maintaining minimal rectal volume before each treatment may not be necessary.

    Weight loss and malnutrition are common among cancer patients, these two factors greatly affecting survival and quality of life during treatment. Since cancer is becoming increasingly common in the world and in order to provide better treatment measures, it is important to identify and prevent side effects. The present study has been conducted in 2010 on a sample of cancer patients in the oncology center of Shahid Beheshti University of Medical Sciences to determine the prevalence rates of malnutrition and the factors affecting it. The PG-SGA standard questionnaire was administered to 416 cancer patients to evaluate their nutrition status and determine the frequency of each malnutrition stage. Correlations and ANOVA tests were used to analyze the relationship between factors and weight loss and how they might affect the development of malnutrition. The prevalence of malnutrition among the patients was 53.1% out of which 29.1% had moderate and 24% had severe malnutrition. The most common factors inducing nutritional symptoms were depression and anorexia. Some 35 % of the patients had over 5% weight loss in the last mouth. The average PG-SGA score was 10.1 with 49 being the highest. 46.1 percent of the patients scored over 9 (requiring critical nutrient intervention). Malnutrition has a high correlation with weight loss, activity limitations, nutritional symptoms, and cancer stage, but low correlation with treatment and pathologic type. Malnutrition has a high prevalence in Iranian cancer patients and has a close relationship with mortality, morbidity and treatment-related problems and also quality of life. Therefore, periodical assessment by PG-SGA to detect malnutrition in patients should be made so that appropriate nutritional interventions can be provided.

    Previous studies have noted a possible association between periodontal diseases and the risk of various cancers. We assessed cancer risk in a cohort of patients with moderate to severe periodontitis. Patients diagnosed with moderate to severe periodontitis by a periodontist between 2001 and 2010 were identified from the hospital registry. Patients younger than 35 years of age or with a prior cancer diagnosis were excluded. The age- and gender-standardized incidence rates (SIR) were calculated by dividing the number of observed cases by the number of expected cases from Turkish National Cancer Registry 2013 data. A total of 280 patients were included (median age 49.6, 54% female). Median follow-up was 12 years. Twenty-five new cancer cases were observed. Patients with periodontitis had 77% increased risk of cancer (SIR 1.77, 95% CI 1.17-2.58, p = .004). Women with periodontitis had significantly higher risk of breast cancer (SIR 2.40, 95% CI 0.88-5.33) and men with periodontitis had significantly higher risk of prostate cancer (SIR 3.75, 95% CI 0.95-10.21) and hematological cancers (SIR 6.97, 95% CI 1.77-18.98). Although showing a causal association necessitates further investigation, our results support the idea that periodontitis might be associated with increased cancer risk, particularly with hematological, breast and prostate cancers.

    AIM: To assess the significance of interleukin (IL)-24 and vascular endothelial growth factor (VEGF) expression in lymph-node-positive rectal cancer. METHODS: Between 1998 and 2005, 90 rectal adenocarcinoma patients with lymph node involvement were enrolled. All patients received radical surgery and postoperative pelvic chemoradiotherapy of 50.4-54.0 Gy. Chemotherapy of 5-fluorouracil and leucovorin or levamisole was given intravenously during the first and last week of radiotherapy, and then monthly for about 6 mo. Expression of IL-24 and VEGF was evaluated by immunohistochemical staining of surgical specimens, and their relations with patient characteristics and survival were analyzed. The median follow-up of surviving patients was 73 mo (range: 52-122 mo). RESULTS: IL-24 expression was found in 81 out of 90 patients; 31 showed weak intensity and 50 showed strong intensity. VEGF expression was found in 64 out of 90 patients. Negative and weak intensities of IL-24 expression were classified as negative expression for analysis. IL-24 expression was significantly reduced in poorly differentiated tumors in comparison with well or moderately differentiated tumors (P = 0.004), N2b to earlier N stages (P = 0.016), and stage IIIc to stage IIIa or IIIb (P = 0.028). The number of involved lymph nodes was also significantly reduced in IL-24-positive patients in comparison with IL-24-negative ones.There was no correlation between VEGF expression and patient characteristics. Expression of IL-24 and VEGF was not correlated with survival, but N stage and stages were significantly correlated with survival. CONCLUSION: IL-24 expression was significantly correlated with histological differentiation, and inversely correlated with the degree of lymph node involvement in stage III rectal cancer.

    The purpose of this study was to explore the relationships among cancer impact, belief in complementary and alternative medicine (CAM), CAM use, and quality of life (QOL). The study used a cross-sectional, descriptive correlational design with convenience sampling. A total of 122 cancer patients participated. Data were collected at a medical center in Chunghua, Taiwan. The questionnaires included the Chinese version of the Cancer Problem in Living Scale (CPILS), Complementary and Alternative Medicine Belief Inventory (CAMBI), Complementary and Alternative Medicine scale, and Chinese versions of QOL scales, including the Functional Assessment of Cancer Therapy-General (FACT-G). The mean age was 56.5 years, and most participants were male (n = 69, 56.6%), had completed high school or above (n = 56, 45.9%), and were married (n = 109, 89.3%). The most common type of cancer was oral (n = 17, 13.9%), followed by esophageal (n = 15, 12.3%) and colorectal (n = 13, 10.7%). Cancer patients, on average, use one or two types of CAM. The impact of cancer is significantly related to age (F = 7.12, p cancer was highly negatively associated with QOL (r = -0.71, p = 0.001). The predictors of QOL were the impact of cancer and use of CAM, and the impact of cancer accounted for 51% of the variance in QOL. This study supports research on the impact of cancer, belief in CAM, and use of CAM as related to QOL in cancer patients. These results can be used to provide options to clinicians and cancer patients.

    Malnutrition is a common problem among cancer patients, usually occurs due to poor appetite, low food intake, and changes in body metabolism. The aim of this study is to determine the prevalence of malnutrition in patients receiving chemotherapy on an outpatient basis. This cross-sectional study conducted on 300 cancer patients referred to hospital. The prevalence of malnutrition among patients was assessed using the abridged scored patient-generated subjective global assessment (abPG-SGA) standard questionnaire. Moreover, patient's weight and 24 h dietary recall were measured. Descriptive statistics were used to present characteristics of patients and dietary recalls. For revealing the correlation, Spearman correlation was used. The average abPG-SGA score was 7.6 (standard deviation [SD] = 5.4) and 60.7% of patients were malnourished and required nutritional intervention. Patients mean age and mean duration of illness were 54.2 (SD = 14.7(years, 25 months, respectively. The most common complaint of patients included fatigue (51.3%), anorexia (43.3%), and dry mouth (41%). Reduction in food intake in past month was reported by 41.7% of patients. According to the high prevalence of cancers and increasing growth of them in recent years with regard to outpatient treatment development for cancer patients, using the abPG-SGA standard questionnaire by nutritionist or nurses can be effective to detect malnourished patients and reduce complications caused by disease.

    Background. The aim of this review is to present common psychosocial problems in cancer patients and their possible coping strategies. Cancer patients are occupied with many psychosocial problems, which are only partially related to their health state and medical treatments. They are faced with a high social pressure, based on prejudices and stereotypes of this illness. The review presents the process of confrontation with the cancer diagnosis and of managing the psychological consequences of cancer. The effects of specific coping styles, psychosocial interventions and a social support on initiation, progression and recurrence of cancer are also described. Conclusions. Although some recent meta-analysis could not provide scientific evidence for the association between coping strategies and the cancer initiation, the progression or the recurrence (neither have studies rejected the thesis of association), the therapeutic window for the psychosocial intervention is still wide and shows an important effect on the quality of lives of many cancer patients.

    Full Text Available Background: Mortality from breast cancer decreased in high-income countries, while countries with middle and low incomes as Brazil still has upward trend. However, large geographical variations among the federal units are observed in the country. The aim of the study was to evaluate the trend of specific mortality from breast cancer in women over 20 years old years among different states of Brazil from 1996 to 2012.  Methods and Findings: Ecological study, using linear regression model for temporal analysis of specific mortality coefficient from malignant neoplasm of breast. We also checked the degree of its correlation with the HDI for the states of Brazil during the stated period. There was an increase in the specific mortality rate for malignant neoplasm of the breast in order of 33%, with range from 23.2 to 30.8 / 100,000 inhabitants. The states with the highest human development HDI in 2010, showed the largest specific mortality rates of breast cancer. Conclusion: Taking the trends of mortality from cancer an important role, this study confirms the need for improvements in mammography coverage, following radiological lesions suspected and access to appropriate therapy.

    Full Text Available A characteristic feature of many cancer types is their ability to metastasise to the skeleton. Bone is the most common site of metastatic invasion, after hematogenous spreading of breast cancer. Early detection of bone metastases is mandatory in the evaluation and management of these patients. Bone scintigraphy is commonly performed in detection and evaluation bone metastases. Tumor markers are present in healthy individuals as well as in patients with malignant diseases but in different concentration. Aim of study was to correlate serum levels of tumor marker Ca (15-3, CEA and presence of bone metastases detected by bone scintigraphy. Study included 25 patients with breast cancer, previously surgically treated. All patients underwent whole body scintigraphy. Ca (15-3 and CEA was measured by radioimmunoassay. Presence, number of bone metastases were correlated with Ca (15-3 and CEA levels. Median age of patients included in study was 50 varying from 30 to 67. Bone scintigraphy revealed bone metastases in 16 (64% patients. A weak correlation was found between number of metastases and level of Ca (15-3 (r=0.139, p=0.254. Significant differences in Ca (15-3 level was found in patient with metastases compared to patients without metastases (chi square 0, p=1.0. Good correlation was found between number of metastases and serum level of CEA. Correlation between level of two tumor markers Ca (15-3 and CEA was a weak (r = 0.096 , p=0.323. Bone scintigraphy is a sensitive diagnostic toll for detecting breast cancer metastases to bone. Serum levels of tumor markes in isolation can not give complete accuracy about bone metastases.

    Non-AIDS-defining cancers are a rising health concern among HIV-infected patients. Cancer screening is now an important component of health maintenance in HIV clinical practice. The decision to screen an HIV-infected patient for cancer should include an assessment of individualized risk for the particular cancer, life expectancy, and the harms and benefits associated with the screening test and its potential outcome. HIV-infected patients are at enhanced risk of several cancers compared to the general population; anal cancer, hepatocellular carcinoma, Hodgkin's lymphoma, and lung cancer all have good evidence demonstrating an enhanced risk in HIV-infected persons. A number of cancer screening interventions have shown benefit for specific cancers in the general population, but data on the application of these tests to HIV-infected persons are limited. Here we review the epidemiology and background literature relating to cancer screening interventions in HIV-infected persons. We then use these data to inform a conceptual model for evaluating HIV-infected patients for cancer screening.

    Mel-18 is a member of the polycomb group (PcG) of proteins, which are chromatin regulatory factors that play an important role in development and oncogenesis. This study was designed to investigate the clinical and prognostic significance of Mel-18 in the patients with prostate cancer. Immunostaining with Mel-18 specific antibodies was performed on paraffin sections from 202 patients. Correlations between Mel-18 and the Gleason grading system, clinical stage, serum prostate-specific antigen (PSA) levels, and age were evaluated. PSA recurrence in 76 patients who underwent radical prostatectomy and survival in 59 patients with metastases at diagnosis were analyzed to evaluate the influence of Mel-18 expression in cancer progression using Kaplan-Meier analysis and multivariate Cox regression analysis. Staining was seen in all prostatic tissues. Mel-18 expression was significantly reduced in the prostate cancer patients with PSA levels over 100 ng/ml (P=0.009), advanced clinical stage (>T4, N1, or M1 disease, P=0.029), higher Gleason grade or with a higher Gleason score (P=0.018) than in those with other clinicopathologic features. Negative expression of Mel-18 was associated with significantly higher rates of PSA recurrence after radical prostatectomy than with positive expression of Mel-18 (P = 0.029), and was an independent predictor of PSA recurrence (P=0.034, HR=2.143) in multivariate analysis. Similarly, metastatic prostate cancer patients with negative expression of Mel-18 showed significantly worse survival compared with the positive expression of Mel-18 (P=0.025). In multivariate analysis, negative expression of Mel-18 was an independent predictor of cancer-specific survival (P=0.024, HR=2.365). Our study provides important evidence for the recognition of Mel-18 as a tumor suppressor. The expression of Mel-18 showed potential as a prognostic marker for human prostate cancer.

    Full Text Available A high frequency of IgA1-positive tumour cells was found in tissue micro-arrays of oesophagus, colon, testis, lung, breast, bladder and ovarian cancer. IgA1 was observed in the cytoplasm and the plasma membrane. A correlation was found between intra-tumour IgA1 and poor overall survival in a large cohort of bladder cancer patients (n = 99, p = 0.011, log-rank test. The number of IgA1-positive tumour cells was also found to be higher in female than male bladder cancer patients. The presence of IgA1 was confirmed in formalin-fixed paraffin-embedded ovarian carcinoma samples using LC-MS/MS analysis. Uptake of IgA1 was also observed in breast cancer and melanoma cell lines when cultivated in the presence of serum from healthy individuals, indicating a possible origin of the IgA1 antibodies in cancer cells.

    Full Text Available Active religious practice is central to Muslim livelihood. Among Muslims, this religious engagement is rarely studied with regards to its association in coping with critical illnesses. This study investigated the association between Islamic religiosity with depression and anxiety in Muslim cancer patients. Fifty-nine cancer patients recruited from a Malaysian public hospital and a cancer support group completed the Muslim Religiosity and Personality Inventory, Beck Depression Inventory and Beck Anxiety Inventory in July and August 2010. Islamic religiosity score, obtained from the sum of subscale scores of Islamic worldview and religious personality represents a greater understanding and practice of Islam in a comprehensive manner. Results yielded a significant negative correlation between Islamic religiosity score with both depression and anxiety. Depression was also found to be negatively associated with religious personality subscale. Older patients scored significantly higher on both Islamic worldview and religious personality whereas patients with higher education scored higher on Islamic worldview. Married patients scored significantly higher scores on religious personality than the single patients. Results provided an insight into the significant role of religious intervention which has huge potentials to improve the psychological health of cancer patients particularly Muslims in Malaysia. Research implication includes the call for professionals to meet the spiritual needs of Muslim cancer patients and incorporating religious components in their treatment, especially in palliative care.

    When a patient is diagnosed with cancer, feelings such as fear, anxiety, and hopelessness can negatively affect a person's frame of mind. Hope can help a patient decrease anxiety and increase quality of life. Nurses should assess hope, provide interventions, be empathetic, listen, and treat patients with dignity to help improve hope and quality of life. This article features how hope can have a positive impact and provides specific information about how nurses can promote and foster hope in patients with cancer.

    Diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) are widely used for detecting uterine endometrial cancer. The relationships between ADC values and pathological features of endometrial cancer have not yet been established. To investigate whether ADC values of endometrial cancer vary according to histologic tumor cellularity and tumor grade. We retrospectively reviewed 30 pathologically confirmed endometrial cancers. All patients underwent conventional non-enhanced magnetic resonance imaging (MRI) and DWI procedures, and ADC values were calculated. Tumor cellularity was evaluated by counting cancer cells in three high-power ( × 400) fields. The correlation between ADC values and tumor cellularity was assessed using Pearson's correlation coefficient test for statistical analysis. The mean ± standard deviation (SD) ADC value ( ×10(-3) mm(2)/s) of endometrial cancer was 0.85 ± 0.22 (range, 0.55-1.71). The mean ± SD tumor cellularity was 528.36 ± 16.89 (range, 298.0-763.6). ADC values were significantly inversely correlated with tumor cellularity. No significant relationship was observed between ADC values and tumor grade (mean ADC values: G1, 0.88 ± 0.265 × 10(-3) mm(2)/s; G2, 0.80 ± 0.178 × 10(-3) mm(2)/s; G3, 0.81 ± 0.117 × 10(-3) mm(2)/s). There is a significant inverse relationship between ADC values and tumor cellularity in endometrial cancer. No significant differences in average ADC value were observed between G1, G2, and G3 tumors. However, the lower the tumor grade, the wider the SD. © The Foundation Acta Radiologica 2015.

    To investigate whether background parenchymal enhancement (BPE) and breast cancer would correlate searching for any significant difference of BPE pattern distribution in case of benign or malignant lesions. 386 patients, including 180 pre-menopausal (group 1) and 206 post-menopausal (group 2), underwent MR examination. Two radiologists evaluated MR images classifying normal BPE as minimal, mild, moderate or marked. The two groups of patients were subdivided into 3 categories based on MRI findings (negative, benign and malignant lesions). The distribution of BPE patterns within the two groups and within the three MR categories was calculated. The χ2 test was used to evaluate BPE type distribution in the three patient categories and any statistically significant correlation of BPE with lesion type was calculated. The Student t test was applied to search for any statistically significant difference between BPE type rates in group 1 and 2. The χ2 test demonstrated a statistically significant difference in the distribution of BPE types in negative patients and benign lesions as compared with malignant ones (p0.05). Normal BPE could correlate with the risk of breast cancer being such BPE patterns as moderate and marked associated with patients with malignant lesions in both pre and post-menopausal women.

    Steven L Gonias

    Full Text Available LDL receptor-related proteins (LRPs are transmembrane receptors involved in endocytosis, cell-signaling, and trafficking of other cellular proteins. Considerable work has focused on LRPs in the fields of vascular biology and neurobiology. How these receptors affect cancer progression in humans remains largely unknown. Herein, we mined provisional databases in The Cancer Genome Atlas (TCGA to compare expression of thirteen LRPs in ten common solid malignancies in patients. Our first goal was to determine the abundance of LRP mRNAs in each type of cancer. Our second goal was to determine whether expression of LRPs is associated with improved or worsened patient survival. In total, data from 4,629 patients were mined. In nine of ten cancers studied, the most abundantly expressed LRP was LRP1; however, a correlation between LRP1 mRNA expression and patient survival was observed only in bladder urothelial carcinoma. In this malignancy, high levels of LRP1 mRNA were associated with worsened patient survival. High levels of LDL receptor (LDLR mRNA were associated with decreased patient survival in pancreatic adenocarcinoma. High levels of LRP10 mRNA were associated with decreased patient survival in hepatocellular carcinoma, lung adenocarcinoma, and pancreatic adenocarcinoma. LRP2 was the only LRP for which high levels of mRNA expression correlated with improved patient survival. This correlation was observed in renal clear cell carcinoma. Insights into LRP gene expression in human cancers and their effects on patient survival should guide future research.

    The purpose of our study was to characterize the causes of death among cancer patients as a function of objectives: (i) calendar year, (ii) patient age, and (iii) time after diagnosis. US death certificate data in Surveillance, Epidemiology, and End Results Stat 8.2.1 were used to categorize cancer patient death as being due to index-cancer, nonindex-cancer, and noncancer cause from 1973 to 2012. In addition, data were characterized with standardized mortality ratios (SMRs), which provide the relative risk of death compared with all persons. The greatest relative decrease in index-cancer death (generally from > 60% to deaths were stable (typically >40%) among patients with cancers of the liver, pancreas, esophagus, and lung, and brain. Noncancer causes of death were highest in patients with cancers of the colorectum, bladder, kidney, endometrium, breast, prostate, testis; >40% of deaths from heart disease. The highest SMRs were from nonbacterial infections, particularly among 1,000 for lymphomas, P death from index- and nonindex-cancers varies widely among primary sites. Risk of noncancer deaths now surpasses that of cancer deaths, particularly for young patients in the year after diagnosis. © The Author 2016.

    Aim of the study was to evaluate nutritional status in patients after gastrectomy due to gastric cancer. In 55 (26 males and 29 females) gastric cancer patients after gastrectomy body composition (bioimpedansometry method); resting energy expenditures and home actual nutrition (frequency analysis method) were evaluated. Blood levels of major nutrients and metabolites were assessed. Both men and women suffered from weight loss after gastrectomy (mean BMI was 19,8+/-4,7 kg/m2 in men and 20,5+/-1,9 in women). Higher BMI was positively correlated with age in women (R=0,45; pgastric cancer patients low BMI, low fat mass and energy consumption are observed even long period of time after gastrectomy. Dietary counseling and support are badly needed in patients short-term as well as long-term period after gastrectomy in men and younger women.

    Experimental evidence suggests that matrix metalloproteinase-13 (MMP-13) protein may promote breast tumor progression. However, its relevance to the progression of human breast cancer is yet to be established. Furthermore, it is not clear whether MMP-13 can be used as an independent breast cancer biomarker. This study was conducted to assess the expression profile of MMP-13 protein in invasive breast carcinomas to determine its diagnostic and prognostic significance, as well as its correlation with other biomarkers including estrogen receptor (ER), progesterone receptor (PR), Her-2/neu, MMP-2, MMP-9, tissue inhibitor of MMP-1 and -2 (TIMP-1 and TIMP-2). Immunohistochemistry (IHC) was performed on paraffin-embedded tissue microarray containing specimens from 263 breast carcinomas. The intensity and the extent of IHC were scored by pathologists in blind fashion. The correlation of the gene expression profiles with patients' clinicopathological features and clinical outcomes were analyzed for statistical significance. MMP-13 protein was detected in the cytoplasm of the malignant cells and the peritumoral stromal cells. MMP-13 expression by tumor cells (p < 0.001) and stromal fibroblasts (p <0.001) both correlated with carcinoma infiltration of lymph nodes. MMP-13 also correlated with the expression of Her-2/neu (p = 0.015) and TIMP-1 (p < 0.010), respectively in tumor cells. Tumor-derived, but not stromal fibroblast-derived, MMP-13 correlated with aggressive tumor phenotypes. Moreover, high levels of MMP-13 expression were associated with decreased overall survival. In parallel, the prognostic value of MMP-13 expressed by peritumoral fibroblasts seems less significant. Our data suggest that lymph node status, tumor size, Her-2/neu expression, TIMP-1 and MMP-13 expression in cancer cells are independent prognostic factors. Tumor-derived, but not stromal fibroblast-derived, MMP-13 correlated with aggressive tumor phenotypes, and inversely correlated with the

    To compare the outcomes of patients having thyroid cancer among Filipinos vs non-Filipinos. Retrospective medical record review. High-volume tertiary referral center in Toronto, Ontario, Canada. A total of 499 patients with thyroid cancer (36 Filipino and 463 non-Filipino) treated at Mount Sinai Hospital from January 1, 1984, to August 31, 2003, with a minimum 5-year follow-up period and a minimum 1.0-cm tumor size. Patients were identified from a thyroid cancer database. Data on patient, tumor, and treatment factors were collected along with outcomes. The presence of thyroid cancer recurrence, the rate of death from disease, and the time to recurrence. The 2 groups were similar for sex, age, history of head and neck radiation exposure, family history of thyroid cancer, follow-up time, tumor size, tumor pathologic findings, presence of tumor multifocality, stage of primary disease, type of thyroid surgery, use of postoperative radioactive iodine therapy, and use of external beam radiation therapy. Filipino patients experienced a thyroid cancer recurrence rate of 25% compared with 9.5% for non-Filipino patients (odds ratio, 3.20; 95% confidence interval, 1.23-7.49; P = .004). On multivariate analysis, the increased risk of thyroid cancer recurrence persisted for Filipino patients (odds ratio, 6.99; 95% confidence interval, 2.31-21.07; P Filipino patients and non-Filipino patients regarding the rate of death from disease (5.6% vs 1.9%) and the time to recurrence (52.6 vs 53.1 months). Filipino patients have a significantly higher risk of thyroid cancer recurrence compared with non-Filipino patients. However, no significant difference was noted in the time to recurrence or the rate of death from disease. These findings justify a more aggressive initial management and follow-up regimen for Filipino patients with thyroid cancer.

    The criteria for refraining from cardiopulmonary resuscitation in palliative care cancer patients are based on patients' right to refuse treatment and the duty of the treating personnel not to exacerbate their suffering and not to administer futile treatment. When is cardiopulmonary resuscitation futile in these patients? Systematic literature searches were conducted in PubMed for the period 1989-2010 on the results of in-hospital cardiopulmonary resuscitation in advanced cancer patients and on factors that affected the results of CPR when special mention was made of cancer. The searches yielded 333 hits and 18 included articles: four meta-analyses, eight retrospective clinical studies, and six review articles. Cancer patients had a poorer post-CPR survival than non-cancer patients. Survival declined with increasing extent of the cancer disease. Widespread and therapy-resistant cancer disease coupled with a performance status lower than WHO 2 or a PAM score (Pre-Arrest Morbidity Index) of above 8 was regarded as inconsistent with survival after cardiopulmonary resuscitation. Cardiopulmonary resuscitation is futile for in-hospital cancer patients with widespread incurable disease and poor performance status.

    The objective is to assess if tumor size after radiotherapy in patients with rectal cancer can be assessed by a second magnetic resonance imaging (MRI), after radiotherapy prior to surgery and to correlate changes observed on MRI with findings at histopathology at surgery. Twenty-five patients with MRI before and after radiotherapy were included. Variables studied were changes in tumor size, T-staging and distance to the circumferential resection margin (CRM). RVs was measured as tumor volume at surgery (Vs) divided by tumor volume at the initial MRI (Vi) in percent. RVm was defined as the tumor volume at the second MRI (Vm) divided by Vi in percent. The ypT-stage was the same or more favorable than the initial MRI T-stage in 24 of 25 patients. The second MRI was not more accurately predictive than the initial MRI for ypT-staging or distance to CRM (p > 0.05). Vm correlated significantly to Vs, as did RVs to RVm, although the former was always smaller than the latter. Vm and RVm correlated well with ypT-stage (p < 0.001). Volumetry seems to correlate with ypT-stage after preoperative radiotherapy for resectable rectal cancer. The value of a second MRI after radiotherapy for assessment of distance to CRM and ypT-staging is, however, not apparent. (orig.)

    To investigate the causes of gastric wall shortening in early gastric cancer, upper gastrointestinal study was correlated with pathologic findings. We evaluated 41 cases (M:F = 1.7:1, average age = 49) of early gastric cancer, retrospectively. The gastric wall shortening were classified as Grade I; none, Grade II; intermediate, and Grade III; prominent. Pathologic findings such as size of lesions, depth of tumor invasion, degree of the submucosal fibrosis, degree of thickness of the submucosa and muscularis propria, and morphologic patterns of lesions including conversing mucosal folds were correlated with the degree of gastric wall shortening on upper gastrointestinal series. Submucosal fibrosis was present in 4 cases in Grade I (n = 21), 4 cases in Grade II (n = 6) and 8 cases in Grade III (n = 10). Positive conversing mucosal folds were seen in 5 cases in Grade I (n = 17), 0 case in Grade II (n = 2) and 9 cases in Grade III (n = 9). Gastric wall shortening was significantly associated with submucosal fibrosis and conversing mucosal folds of early gastric cancer. (ρ = 0.0001, and ρ = 0.02, respectively) Upper gastrointestinal finding of gastric wall protrusion in patients with early gastric cancer should not misinterprete as advanced gastric cancer since the finding could be a result of submucosal fibrosis

    2004-01-01

    Fatigue is one of the most prevalent and profound symptoms related to both malignancy and anti-neoplastic treatment. It is being reported in 60% to 80% of cancer patients. We review the correlation between the cancer-related fatigue syndrome and radiotherapy. In patients undergoing radiotherapy, fatigue is often cumulative and may reach its peak during the last weeks of treatment. The presence of fatigue prior to therapy initiation is the most important predictive factor of the occurrence of radiotherapy-related cancer fatigue syndrome. Occasionally, fatigue persists for a prolonged period of months and even years beyond radiotherapy. Anemia may be one of major causative factors responsible for the development of the cancer-related fatigue syndrome. Fatigue has an enormous physical, mental, emotional, and economic impact on cancer patients, their families and care-providers. The treatment of radiation-related fatigue remains unknown. The initial approach should cover efforts aimed at the correction of potential etiologies, especially anemia. Education concerning fatigue greatly benefits some patients. It seems that exercise may be beneficial in relieving fatigue, bearing in mind that the exercise program for cancer patients should be initiated gradually and significantly individualized. (author)

    The role of clusterin in tumor growth and progression remains unclear. Overexpression of cytoplasmic clusterin has been studied in aggressive colon tumors; however, no correlation between clusterin expression and survival in colorectal cancer has been identified to date. We assessed levels of clusterin expression in a group of stage II colorectal cancer patients to assess its utility as a prognostic marker. The study included 251 patients with stage II colorectal cancer. Tissue microarrays were constructed and immunohistochemistry done and correlated with clinical features and long term outcome. Dual immunofluorescence and confocal microscopy were used with terminal deoxynucleotidyl-transferase-mediated dUTP nick-end labeling probes and clusterin antibody to assess the degree of co localization. Percentage epithelial cytoplasmic staining was higher in tumor compared with nonadjacent normal mucosa (P < 0.001). Within the stromal compartment, percentage cytoplamic staining and intensity was lower in tumor tissue compared with normal nonadjacent mucosa (P < or = 0.001). Survival was significantly associated with percentage epithelial cytoplasmic staining (P < 0.001), epithelial cytoplasmic staining intensity (P < 0.001), percentage stromal cytoplasmic staining (P = 0.002), and stromal cytoplasmic staining intensity (P < 0.001). Clusterin levels are associated with poor survival in stage II colorectal cancer.

    Full Text Available Stonin 2 (STON2, which functions in adjusting endocytotic complexes, is probably involved in the monitoring of the internalization of dopamine D2 receptors which have an inhibitory action of dopamine on tumor progression. However, its clinical significance in tumor progression and prognosis remains unclear. We explored the association between STON2 and the clinicopathological characteristics of epithelial ovarian cancer (EOC. The STON2 levels in ovarian cancer and normal cell lines and tissues were detected by real-time PCR and Western blot analyses. STON2 protein expression was also detected by an immunohistochemical analysis. The clinical significance of STON2 expression in ovarian cancer was statistically analyzed. STON2 significantly increased in the ovarian cancer cell lines and tissues compared to the normal ones. In the 89 EOC samples tested, STON2 expression was significantly correlated with intraperitoneal metastasis, intestinal metastasis, intraperitoneal recurrence, ascites containing tumor cells, and CA153 level. Moreover, patients with STON2 protein overexpression were more likely to exhibit platinum resistance and to have undergone neoadjuvant chemotherapy. Patients with high STON2 protein expression had a tendency to have a shorter overall survival and a poor prognosis. A multivariate analysis showed that STON2 was an independent prognostic predictor for EOC patients. In conclusion, STON2 plays an important role in the progression and prognosis of ovarian carcinoma, especially in platinum resistance, intraperitoneal metastasis, and recurrence. STON2 can be a novel antitumor drug target and biomarker which predicts an unfavorable prognosis for EOC patients.

    To evaluate various prognostic factor predictors of residual growth in Relook transurethral resection of bladder tumor (TURBT) in superficial bladder cancer. Also, to evaluate the role of Relook TURBT along with the ploidy for prediction of recurrence and stage progression in these patients. Fifty patients with superficial bladder cancer underwent TURBT after complete evaluation. Ploidy of the tumor specimen was evaluated by flow cytometry. After 4 to 6 weeks of initial TURBT, these patients underwent Relook TURBT. Final treatment was given after the results of the histological evaluation of these specimens. Patients who underwent bladder sparing treatment were followed-up. Of the patients, 28.5% had residual tumor in Relook TURBT. Growth was found to be at the same site in 66.7% and at a different site 33.3%; 75% had single while 25% had multiple residual growth. Residual malignant tissue had a statistically significant correlation with size of the tumor (>3 cm), appearance (solid tumor), number (>3), grade (high), and multiple previous resections. Overall, the up-migration of stage and grade leads to change in treatment in 41.6%; 5 underwent radical cystectomy and 1 opted for radiotherapy; in 2 patients, intravesical BCG was given. In follow-up of mean 11.5 months, 16.6% had recurrence. Presence of residual growth in Relook TURBT along with number, size, morphology, and multiple previous resections were found to have significant correlation with the recurrence in these patients. Ploidy and grade of the tumor were not found to have correlation. Multiple, more than 3 cm, solid high grade tumor with > 3 previous resections were predictors of presence of residual tumor in Relook TURBT. Presence of residual growth is a significant risk factor for recurrence. Ploidy was not found to be significantly correlated with recurrence.

    Gastric cancer remains one of the most common human malignancies with a poor prognosis. Apoptosis is known to be a programmed cell death and its inhibition is involved in the unregulated cellular growth that leads to neoplasms. Microvessel density (MVD) has been investigated as a promoting factor for angiogenesis with conflicting results about its relation to survival. The aim of our study was to search a correlation between these factors and some clinicopathological features and prognosis. Identification of apoptotic cells was performed applying the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling technique and recorded as apoptotic index (A.I.), whereas monoclonal antibodies were used for the study of MVD. A significant correlation was found between low and high A.I. and the subgroup of patients in Stages I and II (P stage (P = 0.036) and to a poorer 5-year overall survival (P gastric cancer.

  17. Nuclear oxidative damage correlates with poor survival in colorectal cancer.

    2012-02-01

    Oxidative DNA damage results from DNA adducts such as 8-oxo-7, 8 dihydro-2\\'-deoxyguanosine (8-oxo-dG), which is a pro-mutagenic lesion. No known association between 8-oxo-dG, disease progression and survival exists in colorectal cancer (CRC). We examined levels of 8-oxo-dG in sporadic CRC to determine its relationship with pathological stage and outcome. A total of 143 CRC patients and 105 non-cancer patients were studied. Nuclear and cytoplasmic 8-oxo-dG was assessed using immunohistochemistry. Double immunofluorescence using 8-oxo-dG and manganese superoxide dismutase (MnSOD) antibodies localised cytoplasmic 8-oxo-dG. Apoptosis was detected using TUNEL. Nuclear staining levels were similar in tumour tissue and matched normal mucosa in both epithelial (P=0.22) and stromal (P=0.85) cells. Epithelial cytoplasmic staining was greater in tumour tissue (P<0.001). Double immunofluorescence localised cytoplasmic 8-oxo-dG to mitochondria. Epithelial and stromal nuclear 8-oxo-dG decreased with local disease spread, but highest levels were found in distant disease (P<0.01). Survival was related to epithelial nuclear and stromal staining in normal mucosa (P<0.001) and tumour (P<0.01) but was unrelated to cytoplasmic staining. Normal control cells in tissue from cancer patients with high levels of 8-oxo-dG failed to undergo cell death. 8-oxo-dG may be an important biomarker of disease risk, progression and survival for CRC patients.

    Full Text Available Objective: To study the correlation of serum GP73, SOD and GPC3 contents with cell proliferation and angiogenesis in liver cancer lesion. Methods: Patients who were diagnosed with primary liver cancer in Jianghan Oilfield General Hospital between June 2014 and February 2017 were selected as liver cancer group, and healthy subjects who received physical examination in Jianghan Oilfield General Hospital during the same period were selected as control group. Serum was collected from two groups of subjects to determine the contents of GP73, SOD and GPC3; liver cancer lesion and adjacent lesion were collected from liver cancer group to determine the expression of cell proliferation molecules and angiogenesis molecules. Results: Serum GP73 and GPC3 levels of liver cancer group were obviously higher than those of control group while SOD content was obviously lower than that of control group; DNMT3B, STC2, SIRT6, LETM1, EphB4, SULT2B1, HIF-1α, VEGF, Ang-2, HGF and TGF-β1 protein expression levels in liver cancer lesion of liver cancer group were significantly higher than those in adjacent lesion; DNMT3B, STC2, SIRT6, LETM1, EphB4, SULT2B1, HIF-1α, VEGF, Ang-2, HGF and TGF-β1 protein expression levels in liver cancer lesion of liver cancer group were positively correlated with serum GP73 and GPC3 levels, and negatively correlated with serum SOD level. Conclusion: The changes of GP73, SOD and GPC3 levels in the serum of patients with liver cancer are closely related to the cell proliferation and angiogenesis in liver cancer lesion.

    2017-10-01

    Full Text Available Successful implementation of treatment in cancer care partially depends on how patients' perspectives are taken into account, as preferences of health care professionals and patients may differ. Objectives of this exploratory research were (I to identify patient preferences and values (PPVs in cancer care as indicated by patient organizations (POs, (II to determine how these PPVs are captured in cancer care guidelines and (III to review how guidelines take into account these PPVs. Based on a survey developed and completed by 19 POs, a literature review was conducted to analyse how patient perspectives are incorporated in oncology treatment guidelines. Based on survey results traditional health technology assessment value propositions of oncology care, such as extended life, treatment-free remission and pain reduction, were also highly rated by POs. However, the heterogeneity of cancer PPVs were clearly reflected in the survey results. PPVs in cancer care guidelines were mostly limited to those micro-level aspects that are strictly related to health care provision, such as side-effects and comorbidities. Patient experience, emotional support and convenience of care were relatively neglected fields in the reviewed guidelines. Patient engagement was rarely presented in the guideline development phase. POs believe that patients should be encouraged to take an active role in their own care due to the heterogeneity of cancer patients and PPVs. Even if patient-centricity is a leading paradigm in cancer policy, based on our research it is not yet standard practice to include patients or POs at all appropriate levels of decision-making processes that are related to their health and well-being. Patient engagement should be an integral part of cancer care decision-making. This complexity must be reflected throughout policy making, avoiding a population level “one-size-fits-all” solution.

    Full Text Available Objective: The purpose of this study is to evaluate the predictors of empathy skills and attitude towards cancer patients and association between nurses’ empathy skills on attitudes towards patients with cancer Patients and Methods: A structured questionnaire was used to evaluate the nurses’ empathy skills and their attitudes towards to patients with cancer. Jefferson Scale of Empathy (JSE and Attitudes towards Cancer Scale (ATCS were used. The predictors of JSE/ATCS scores and correlation between JSE and ATCS were analyzed. Results: 305 nurses participated in the study (84.2% of all nurses. The median age was 33 (20-52 and most of the nurses were female (82.6%. Most of the participants were married (188, 61.6% and 40.3% of nurses had a job experience more than 10 years. Female sex, being married, having job experience more than 10 years or caring more cancer patients were associated with higher JSE scores. Nurses caring more cancer patients weekly, experience with cancer patients, participation in educational activities about cancer care or presence of relative with a diagnosis of cancer were found to have more positive attitudes towards cancer patients. Spearman correlation analysis showed a positive, weak correlation between JSE and ATCS (r= 0.017, P= 0.38 Conclusion: Empathy skills are important while caring patients, especially in oncology practice. Although a direct correlation between empathy skills and attitudes towards cancer patients couldn’t be demonstrated, health care workers caring cancer patients should be both evaluated for empathy skills and educated.

    Cancer patient navigation (PN) programs have been shown to increase access to and utilization of cancer care for poor and underserved individuals. Despite mounting evidence of its value, cancer patient navigation is not universally understood or provided. We describe five PN programs and the range of tasks their navigators provide across the cancer care continuum (education and outreach, screening, diagnosis and staging, treatment, survivorship, and end-of-life). Tasks are organized by their potential to make cancer services understandable, available, accessible, affordable, appropriate, and accountable. Although navigators perform similar tasks across the five programs, their specific approaches reflect differences in community culture, context, program setting, and funding.

    Availability without prescription restriction, low cost, and simple oral administration allow cancer patients to use probiotics without knowledge of potential risks. We present a survey of probiotic use and the association with patient tumor characteristics in cancer patients treated at the outpatient department of the National Cancer Institute in Slovakia. Between March and December 2014, 499 patients were asked to evaluate their overall experience with probiotics by questionnaire form, including the length and method of use relative to anticancer therapy, expectations, side-effect experiences, understanding of the possible risks, dietary supplement use, and others. The relevant data were statistically evaluated. The cohort consisted of 323 women (64.7%) and 176 men (35.3%); 91.6% were undergoing chemotherapy (2.6% together with radiotherapy) and 8.4% had no anticancer therapy. The prevalence of probiotic use was 28.5% and only 12 patients using probiotics (8.5%) described negative side effects. Most patients declared consideration of probiotic use based on recommendation from a physician (37.3%) or a pharmacist (14.8%). Nevertheless, up to 86.6% of patients declared no knowledge of possible risks. Statistically significant correlation was found between probiotic use and age of patients (P probiotic use in cancer patients. Minimal knowledge of risks underlines the importance of an active approach by oncologists to inform patients about probiotic safety.

    Objective: To understand the variation of the DNA double-strand break rejoining capacity among different cultured cancer cell lines and the primary cancer cells from brain cancer patients, and to explore the predictor of radiotherapy responses of cancers. Methods: DNA double-strand breaks (DSBs) were induced by 60 Co γ-irradiation. Pulsed-field gel electrophoresis was used to analyze the initial production and rejoining of DNA DSBs. Radiosensitivity was determined by in vitro assay of clonogenic-forming capacity. Results: A wide variation of radiosensitivity, e.g. the survival parameter of Do varied from 0.65 to 2.15 Gy, was displayed among the eight cell lines derived from different type of cancers. Although differential level of initial DNA DSBs induced by 20 Gy γ-rays was observed among various cell lines, it was not correlated with the radiosensitivity. The deficiency of DNA DSB rejoining in radiosensitive cell lines was shown either in the early rapid-rejoining phase (SX-10 cells) or in the late slow-rejoining phase (A2780 cells). A significant relationship was observed between the residual level of DNA DSBs measured at 2 h post-20 Gy irradiation and the cellular radiosensitivity (D 0 or SF 2 ). The kinetic curves of rejoining DNA DSBs in the primary human brain tumor cells indicated a variation on DSB rejoining capacity among different individual tumor. The residual level of DNA DSBs after 2 h of rejoining post 20 Gy irradiation in primary human brain tumor cells is compatible to the results obtained in vitro culture cancer cell lines. Conclusions: The residual level of DNA DSBs is correlated with radioresistance of cancer cells, and the residual DNA damage is a useful parameter in predicting the response of tumor tissue to radiotherapy.

    The aim of the study was to assess patients' awareness of the prevention and treatment of colorectal cancer. Patients diagnosed with colorectal cancer, hospitalised at the Department of General and Colorectal Surgery of the Medical University in Łódź during the period from January 2015 to April 2015, were asked to complete a questionnaire concerning their families' medical case record, factors predisposing them to the development of colorectal cancer, the tests applied in diagnostics, and the treatment process. The questionnaire comprised 42 closed-ended questions with one correct answer. A statistical analysis of all answers was carried out. The study group consisted of 30 men and 20 women aged 27-94 years old. A strong, statistically significant negative correlation between a patient's age and his/her awareness of the prevention and treatment of colorectal cancer was noted (pcancer (p=0.008), and the awareness of the prevention programme. The women's group was characterised by statistically significantly greater awareness of colonoscopy as a screening examination (p=0.004). Patients need more information on colorectal cancer, its risk factors, prevention, the treatment process, and postoperative care. Lack of awareness of the colorectal cancer issue can be one of the major factors contributing to the high incidence of this disease.

    The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. © 2015 John Wiley & Sons Ltd.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

    DNA methylation in the SHOX2 locus was previously used to reliably detect lung cancer in a group of critical controls, including 'cytologically negative' samples with no visible tumor cell content, at a high specificity based on the analysis of bronchial lavage samples. This study aimed to investigate, if the methylation correlates with SHOX2 gene expression and/or copy number alterations. An amplification of the SHOX2 gene locus together with the observed tumor-specific hypermethylation might explain the good performance of this marker in bronchial lavage samples. SHOX2 expression, gene copy number and DNA methylation were determined in lung tumor tissues and matched morphologically normal adjacent tissues (NAT) from 55 lung cancer patients. Quantitative HeavyMethyl (HM) real-time PCR was used to detect SHOX2 DNA methylation levels. SHOX2 expression was assayed with quantitative real-time PCR, and copy numbers alterations were measured with conventional real-time PCR and array CGH. A hypermethylation of the SHOX2 locus in tumor tissue as compared to the matched NAT from the same patient was detected in 96% of tumors from a group of 55 lung cancer patients. This correlated highly significantly with the frequent occurrence of copy number amplification (p < 0.0001), while the expression of the SHOX2 gene showed no difference. Frequent gene amplification correlated with hypermethylation of the SHOX2 gene locus. This concerted effect qualifies SHOX2 DNA methylation as a biomarker for lung cancer diagnosis, especially when sensitive detection is needed, i.e. in bronchial lavage or blood samples

    The author's personal experience as a kidney cancer patient, researcher and founder of a kidney cancer support group forms the basis for consideration of the challenges involved in researching patients' experiences. The researcher needs to understand the variability of those experiences in both clinical and psychological-emotional terms, and in relation to the personal, familial and social contexts of the patient. It is also essential to define the purpose of the research and to show how an understanding of personal experiences of cancer can be used to enhance the quality of care for cancer patients. The research encounter with a patient is also in some respects a therapeutic encounter requiring a considerable degree of sensitivity on the part of the researcher. The person-centred approach of Carl Rogers is of value in supporting such an encounter.

    Full Text Available Background: A supportive needs assessment is an essential component of any care program. There is no research evidence regarding the supportive care needs of cancer patients in Iran or other Middle Eastern countries. Aims: The aim of this study was to determine the supportive care needs of Iranian cancer patients. Materials and Methods: This descriptive study was conducted in a referral medical center in the northwest of Iran. A total of 274 cancer patients completed the Supportive Care Needs Survey (SCNS-59. Descriptive statistics were used for data analysis. Results: In 18 items of the SCNS, more than 50% of the participants reported that their needs were unmet. Most frequently, unmet needs were related to the health system, information, physical, and daily living domains, and most met needs were related to sexuality, patient care, and support domains. Conclusions: Iranian cancer patients experience many unmet needs and there is an urgent need for establishing additional supportive care services in Iran.

    Thyroid cancer is a rare malignancy with wide inter ethnic and geographic variations. In Germany thyroid carcinoma is the 13. most frequent malignancy (2.7 new cases yearly per 100,000 inhabitants). The overall temporal incidence is increasing slightly in recent years. The most common types of cancer are papillary (60-80%) and follicular cancers (10-20%). The relevant prognostic indicators are tumor stage and distant metastases. The mean survival rates in papillary thyroid cancer usually exceed 90%, whereas in follicular thyroid cancer they amount to approximately 80%. The standard treatment procedure in differentiated papillary and follicular thyroid cancer consists of total thyroidectomy followed by adjuvant ablative therapy with radioiodine. Only in papillary thyroid cancer stage pT 1 N 0 M 0 lobectomy alone is considered to be appropriate. In patients with locally invasive differentiated thyroid cancers stage pT 4 adjuvant percutaneous radiation therapy is a treatment option. Radioiodine therapy has to be performed under the stimulative influence of TSH. Usually TSH suppressive medication with Levothyroxine has to be withdrawn approximately 4 weeks prior to radioiodine therapy. In the future, exogenous stimulation by recombinant TSH may be used instead of thyroid hormone withdrawal. It has been proved by different studies that ablative radioiodine therapy reduces the frequency of recurrences and tumor spread in patients with thyroid cancer significantly. In patients with distant metastases, up to 50% of complete responses may be achieved with radioiodine treatment

Methods: A total of 140 patients with thyroid nodule who accepted surgical resection in our hospital between May 2013 and June 2016 were selected as the research subjects, the patients with malignant thyroid nodule were included in the malignant group of the research and patients with benign thyroid nodule were included in the benign group of research. Three-dimensional power Doppler ultrasonography was conducted before operation to determine vascularization index (VI, flow index (FI and vascularization flow index (VFI; tumor tissues were collected after operation to detect the expression of angiogenesis as well as cell proliferation, apoptosis and invasion-related molecules. Results: VI, FI and VFI levels of tumor tissue of malignant group were significantly higher than those of benign group; VEGF, MK, Ang-2, IGF-II, Bcl-2, Livin, Wip1, S100A4, TCF, β-catenin and SATB1 protein expression in tumor tissue of malignant group were significantly higher than those of benign group and positively correlated with VI, FI and VFI levels while CCNG2 and p27 protein expression were significantly lower than those of benign group and negatively correlated with VI, FI and VFI levels. Conclusion: Ultrasound vascularization index and flow index of thyroid cancer increase significantly and are closely related to the angiogenesis as well as cell proliferation, apoptosis and invasion.

    Immunotherapies for cancer are transforming patient care, but clinical responses vary considerably from patient to patient. Simple, inexpensive strategies to target treatment to likely responders could substantially improve efficacy while simultaneously reducing health care costs, but identification of reliable biomarkers has proven challenging. Previously, we found that pre-treatment serum IgM to blood group A (BG-A) correlated with survival for patients treated with PROSTVAC-VF, a therapeutic cancer vaccine in phase III clinical trials for the treatment of prostate cancer. These results suggested that ABO blood type might influence efficacy. Unfortunately, blood types were not available in the clinical records for all but 8 patients and insufficient amounts of sera were left for standard blood typing methods. To test the hypothesis, therefore, we developed a new glycan microarray-based method for determining ABO blood type. The method requires only 4 μL of serum, provides 97% accuracy, and allows simultaneous profiling of many other serum anti-glycan antibodies. After validation with 220 healthy subjects of known blood type, the method was then applied to 74 PROSTVAC-VF patients and 37 control patients from a phase II trial. In this retrospective study, we found that type B and O PROSTVAC-VF patients demonstrated markedly improved clinical outcomes relative to A and AB patients, including longer median survival, longer median survival relative to Halabi predicted survival, and improved overall survival via Kaplan-Meier survival analysis (p = 0.006). Consequently, blood type may provide an inexpensive screen to pre-select patients likely to benefit from PROSTVAC-VF therapy.

    Oral cancer is currently the most frequent cause of cancer-related deaths, which is usually preceded by oral pre-cancerous lesions and conditions. Altered glycosylation of glycoconjugates, such as sialic acid, fucose, etc. are amongst the important molecular changes that accompany malignant transformation. The purpose of our study was to evaluate usefulness of serum Total Sialic Acid (TSA) and serum Lipid-Bound Sialic Acid (LSA) as markers of oral precancerous lesions and histopathologically correlating them with grades of epithelial dysplasia. Blood samples were collected from 50 patients with oral precancer (Leukoplakia & OSMF), 25 patients with untreated oral cancer and 25 healthy subjects. Serum sialic acid (total and lipid bound) levels were measured spectrophotometrically. Tissue samples from all the patients were evaluated for dysplasia. Serum levels of total and lipid bound sialic acid were significantly elevated in patients with oral precancer and cancer when compared with healthy subjects. Analysis of variance test documented that there is progressive rise in serum levels of sialic acid with the degree of dysplastic changes in oral precancer patients. We observed positive correlation between serum levels of the markers and the extent of malignant disease (TNM Clinical staging) as well as histopathological grades. The results suggested that serum levels of TSA and LSA progressively increases with grades of dysplasia in precancerous groups and cancer group, when compared with healthy controls. These glycoconjugates, especially LSA has the clinical utility in indicating a premalignant change.

    Purpose: To evaluate the utility of an infrared-guided patient setup (iGPS) system to reduce the uncertainties in the setup of lung cancer patients. Methods and Materials: A total of 15 patients were setup for lung irradiation using skin tattoos and lateral leveling marks. Daily electronic portal device images and iGPS marker locations were acquired and retrospectively reviewed. The iGPS-based shifts were compared with the daily electronic portal device image shifts using both the central axis iGPS marker and all five iGPS markers. For shift calculation using the five markers, rotational misalignment was included. The level of agreement between the iGPS and portal imaging to evaluate the setup was evaluated as the frequency of the shift difference in the range of 0-5 mm, 5-10 mm, and >10 mm. Results: Data were obtained for 450 treatment sessions for 15 patients. The difference in the isocenter shifts between the weekly vs. daily images was 0-5 mm in 42%, 5-10 mm in 30%, and >10 mm in 10% of the images. The shifts seen using the iGPS data were 0-5 mm in 81%, 5-10 mm in 14%, and >10 mm in 5%. Using only the central axis iGPS marker, the difference between the iGPS and portal images was 10 mm in 7% in the left-right direction and 73%, 18%, and 9% in the superoinferior direction, respectively. When all five iGPS markers were used, the disagreements between the iGPS and portal image shifts >10 mm were reduced from 7% to 2% in the left-right direction and 9% to 3% in the superoinferior direction. Larger reductions were also seen (e.g., a reduction from 50% to 0% in 1 patient). Conclusion: The daily iGPS-based shifts correlated well with the daily electronic portal device-based shifts. When patient movement has nonlinear rotational components, a combination of surface markers and portal images might be particularly beneficial to improve the setup for lung cancer patients

    Objective: To evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (MRI) in the diagnose of prostatic cancer and benign prostatic hyperplasia (BPH), and to determine the correlation between dynamic MRI findings with angiogenesis. Methods: Thirty-two cases of prostatic cancer and 40 cases of BPH underwent dynamic contrast-enhanced MRI. All the patients in this study were diagnosed by histopathology. The results of dynamic contrast-enhanced MRI were evaluated by early-phase enhancement parameters and time-signal intensity curves (SI-T curves), and the curves were classified according to their shapes as type I, which had steady enhancement; type II, plateau of signal intensity; and type III, washout of signal intensity. The pathologic specimens of region of interest (ROI ) were obtained, and HE staining, immunohistochemical vascular endothelial growth factor (VEGF), and microvessel density (MVD) measurements were performed. The relationships among dynamic contrast-enhanced MRI features, VEGF, and MVD expression were analyzed. Results: In the early-phase enhancement parameters of dynamic contrast-enhanced MRI, onset time, maximum signal intensity, and early-phase enhancement rate differed between prostatic cancer and BPH (P<0.01, 0.05, 0.01), but there were some overlaps between them. The intermediate and late post-contrast periods were characterized with the lesion SI-T curves. The SI-T curve of prostatic cancer was mainly type III (21 cases). Type II could be seen in both prostatic cancer (8 cases) and BPH (19 cases). Type I most appeared in BPH (18 cases). The distributions proved to have significant difference (P<0.001). The mean VEGF and MVD level of 32 prostatic cancer patients were significantly higher than those of 40 BPH patients (P<0.001). MVD level of prostatic cancer and BPH showed an association with VEGF level (P<0.01). The maximum signal intensity and early-phase enhancement rate in both prostatic cancer and BPH showed an association

    RNA binding proteins (RBPs) are pivotal post-transcriptional regulators. RNPC1, an RBP, acts as a tumor suppressor through binding and regulating the expression of target genes in cancer cells. This study disclosed that RNPC1 expression was positively correlated with breast cancer patients' relapse free and overall survival, and RNPC1suppressed breast cancer cells metastasis. Mechanistically, RNPC1 promoting a competing endogenous network (ceRNA) crosstalk between STARD13, CDH5, HOXD10, and HOXD1 (STARD13-correlated ceRNA network) that we previously confirmed in breast cancer cells through stabilizing the transcripts and thus facilitating the expression of these four genes in breast cancer cells. Furthermore, RNPC1 overexpression restrained the promotion of STARD13, CDH5, HOXD10, and HOXD1 knockdown on cell metastasis. Notably, RNPC1 expression was positively correlated with CDH5, HOXD1 and HOXD10 expression in breast cancer tissues, and attenuated adriamycin resistance. Taken together, these results identified that RNPC1 could inhibit breast cancer cells metastasis via promoting STARD13-correlated ceRNA network.

    Full Text Available BackgroundRecently, several studies reported that the cancer incidence in type 2 diabetes patients is higher than in the general population. Although a number of risks are shared between cancer and diabetes patients, there have been few studies of its correlation. We evaluated the influences of several factors including low density lipoprotein cholesterol (LDL-C, albuminuria and use of metformin on the risk of cancer in patients with type 2 diabetes.MethodsWe enrolled 1,320 patients with at least 5 years of follow-up and 73 patients were diagnosed with cancer during this period. The associations of the risk factors with cancer incidence were evaluated by multiple regression analysis. The subjects were placed into two subgroups based on metformin dosage (<1,000 mg/day, ≥1,000 mg/day and we compared cancer incidence using analysis of covariance.ResultsLDL-C and albuminuria were not significantly correlated with cancer risk. In contrast, metformin showed a reverse correlation with cancer risk (P=0.006; relative risk, 0.574. In the metformin nonadministration group, smoking, male gender, and high triglyceride levels tended to be contributing factors without statistical significance. Cancer occurence was lower in the low dose metformin group (less than 1,000 mg/day (P=0.00.ConclusionThese results suggest that the administration of low dose metformin in patients with type 2 diabetes may be associated with a reduced risk of cancer.

    Full Text Available Abstract Background Optimizing treatment through microarray-based molecular subtyping is a promising method to address the problem of heterogeneity in breast cancer; however, current application is restricted to prediction of distant recurrence risk. This study investigated whether breast cancer molecular subtyping according to its global intrinsic biology could be used for treatment customization. Methods Gene expression profiling was conducted on fresh frozen breast cancer tissue collected from 327 patients in conjunction with thoroughly documented clinical data. A method of molecular subtyping based on 783 probe-sets was established and validated. Statistical analysis was performed to correlate molecular subtypes with survival outcome and adjuvant chemotherapy regimens. Heterogeneity of molecular subtypes within groups sharing the same distant recurrence risk predicted by genes of the Oncotype and MammaPrint predictors was studied. Results We identified six molecular subtypes of breast cancer demonstrating distinctive molecular and clinical characteristics. These six subtypes showed similarities and significant differences from the Perou-Sørlie intrinsic types. Subtype I breast cancer was in concordance with chemosensitive basal-like intrinsic type. Adjuvant chemotherapy of lower intensity with CMF yielded survival outcome similar to those of CAF in this subtype. Subtype IV breast cancer was positive for ER with a full-range expression of HER2, responding poorly to CMF; however, this subtype showed excellent survival when treated with CAF. Reduced expression of a gene associated with methotrexate sensitivity in subtype IV was the likely reason for poor response to methotrexate. All subtype V breast cancer was positive for ER and had excellent long-term survival with hormonal therapy alone following surgery and/or radiation therapy. Adjuvant chemotherapy did not provide any survival benefit in early stages of subtype V patients. Subtype V was

Adjuvant chemotherapy of lower intensity with CMF yielded survival outcome similar to those of CAF in this subtype. Subtype IV breast cancer was positive for ER with a full-range expression of HER2, responding poorly to CMF; however, this subtype showed excellent survival when treated with CAF. Reduced expression of a gene associated with methotrexate sensitivity in subtype IV was the likely reason for poor response to methotrexate. All subtype V breast cancer was positive for ER and had excellent long-term survival with hormonal therapy alone following surgery and/or radiation therapy. Adjuvant chemotherapy did not provide any survival benefit in early stages of subtype V patients. Subtype V was consistent with a unique subset of luminal A intrinsic

    To analyze the relation between nutrition and quality of life in the stomach cancer patients, evaluate the intake of daily nutrition of the patients, and study the feasibility of nutrition intervention in improving quality of life of the stomach cancer patients. A total of 285 surgical stomach cancer patients reported in the Changle Cancer Registry from 2002 to 2003 were investigated with respect to their diet and quality of life. Daily nutrition intakes of the patients were calculated according to the Food Composition Database, and these data were compared with the reference values proposed by the Chinese Nutrition Society. The partial correlation was used to analyze the relationship between nutrition and quality of life in the patients. Stepwise multiple regression analyses were conducted to analyze the factors influencing nutrition intake in stomach cancer patients. Except vitamin C, there were statistical correlations between the nutrition and quality of life in stomach cancer patients, and differences of the daily nutrition intake among three groups (good, modest and bad quality of life) of the patients were significant. Most of the stomach cancer patients had a lower daily nutrition intake than the reference values. At the significance level alpha = 0.05, the factors influencing the daily nutrition intake of the patients were number of meals a day, family income, way of operation, exercise and age. The nutritional status of the operated patients with stomach cancer may impact on their quality of life. The stomach cancer patients in Changle County have a low level of daily nutrition intake, which suggests that they have a bad nutritional status. To improve the quality of life of the patients, the nutrition intervention should be conducted. Increasing times of meals a day and having a high-protein, high-calorie foods can improve the nutritional status of the stomach cancer patients. Moreover, exercise for rehabilitation can whet the appetite of the patients and

    Understanding the informational needs of cancer patients is a requirement to plan any educative care program for them. The aim of this study was to identify Iranian cancer patients' perceptions of informational needs. The study took a qualitative approach. Semi-structured interviews were held with 25 cancer patients in two teaching hospitals in Iran. Transcripts of the interviews underwent conventional content analysis, and categories were extracted. The results came under two main categories: disease-related informational needs and information needs related to daily life. Disease-related informational needs had two subcategories: obtaining information about the nature of disease and obtaining information about disease prognosis. Information needs related to daily life also had two subcategories: obtaining information about healthy lifestyle and obtaining information about regular activities of daily life. The findings provide deep understanding of cancer patients' informational needs in Iran.

    Full Text Available Cognitive behavioral therapy is one of the structured but flexible psychosocial interventions that could be applied to patients with cancer. In many studies the positive effects of cognitive behavioral therapy in reducing psychological morbidity and improving the quality of life of cancer patients have been shown. In this article, the contents and techniques of adapted cognitive behavioral therapy for patients with cancer and its effectiveness in commonly seen psychiatric disorders have been reviewed. The aim of this article is to contribute positively to physicians and nurses in Turkey for early detection of psychological distress and referral to the therapist that would clearly increase the quality of life of cancer patients.

    Full Text Available Background : The spectrum of head and neck tumors in children continues to be the cause of diverse, diagnostically challenging issues. Aims : To demonstrate and compare the unique clinicopathological features in our study population and their correlations with the final histopathological diagnosis. Methods : Fifty-three children with head and neck cancer were examined thoroughly at the Otorhinolaryngology department in a tertiary care teaching hospital followed by histopathological studies. Results : Lymphomas were the most common malignant lesions seen followed by rhabdomyosarcomas, nasopharyngeal carcinomas, and others like thyroid carcinomas and eosinophilic granulomas. In the neck, the commonest cause of primary malignant disease was lymphoma; however, the most frequent lesion was reactive lymphadenitis. In the sinonasal region, the commonest malignancy was rhabdomyosarcoma, which often had extension to the orbit and the face. Recurrent epistaxis was found universally in the malignant cases of this region. In the facial region, disfiguring swelling with proptosis was mainly caused by rhabdomyosarcoma. The only case of tonsillar malignancy was due to non-Hodgkin lymphoma. The duration of disease was less than 1 year. Conclusion : The most common manifestation of the malignant lesions in the pediatric age group was with a history of an enlarging, painless neck swelling. Still, an insignificant lump in the neck or recurrent bleeding from nose may be the manifestation of an underlying cancer.

    Purpose: Damage to heart and lung from breast radiotherapy is associated with increased cardiovascular mortality and lung cancer development. We conducted a prospective study to evaluate which position is best to spare lung and heart from radiotherapy exposure. Methods and Materials: One hundred consecutive Stage 0–IIA breast cancer patients consented to participate in a research trial that required two computed tomography simulation scans for planning both supine and prone positions. The optimal position was defined as that which best covered the contoured breast and tumor bed while it minimized critical organ irradiation, as quantified by the in-field heart and lung volume. The trial was designed to plan the first 100 patients in each position to study correlations between in-field volumes of organs at risk and dose. Results: Fifty-three left and 47 right breast cancer patients were consecutively accrued to the trial. In all patients, the prone position was optimal for sparing lung volume compared to the supine setup (mean lung volume reduction was 93.5 cc for right and 103.6 cc for left breast cancer patients). In 46/53 (87%) left breast cancer patients best treated prone, in-field heart volume was reduced by a mean of 12 cc and by 1.8 cc for the other 7/53 (13%) patients best treated supine. As predicted, supine-prone differences in in-field volume and mean dose of heart and lung were highly correlated (Spearman's correlation coefficient for left breast cancer patients was 0.90 for heart and 0.94 for lung and 0.92 for right breast cancer patients for lung). Conclusions: Prone setup reduced the amount of irradiated lung in all patients and reduced the amount of heart volume irradiated in 87% of left breast cancer patients. In-field organ volume is a valid surrogate for predicting dose; the trial continued to the planned target of 400.

CD44 has been reported to play key roles in cell proliferation, motility, and survival, but its role in breast cancer remains controversial. In this study, we conducted a meta-analysis. A total of 23 published Gene Expression Omnibus databases were included to evaluate the association between CD44 mRNA expression and clinicopathological characteristics or prognosis of the patients with breast cancer. Our analysis revealed that CD44 expression was associated with clinicopathological features, including the histological grade, estrogen receptor status, progesterone receptor status, and human epidermal growth factor receptor-2 status. Higher levels of CD44 expression were observed in the basal subtype of breast cancer both at the mRNA and protein levels (odds ratio [OR] =2.08, 95% confidence interval [CI]: 1.72–2.52; OR =2.11, 95% CI: 1.67–2.68. Patients with CD44 overexpression exhibited significantly worse overall survival (hazard ratio =1.27; 95% CI: 1.04–1.55. Whole gene profile analysis revealed that CD44 expression was enriched in basal-type breast cancer and correlated with epithelial–mesenchymal transition and cancer stem cell gene profiles. In summary, our analyses indicated that CD44 potentially might be a prognostic marker for breast cancer and thus can serve as a therapeutic target for basal-type breast cancer.

    In the present study, we evaluated the relationship between nutritional status, disease stage and quality of life (QoL) in 100 patients recently diagnosed with gastric carcinoma. The patients' nutritional status was investigated with anthropometric, biochemical, inflammatory and functional variables; and we also evaluated the nutritional risk with the Nutritional Risk Screening 2002. Oncological staging was standard. QoL was evaluated using the Functional Assessment of Anorexia/Cachexia Therapy questionnaire. The statistical correlation between nutritional risk score (NRS) and oncological characteristics or QoL was evaluated using both univariable and multivariable analyses. Weight loss and reduction of food intake were the most frequent pathological nutritional indicators, while biochemical, inflammatory and functional variables were in the normal range. According to NRS, thirty-six patients were malnourished or at risk for malnutrition. Patients with NRS ≥ 3 presented a significantly greater percentage of stage IV gastric cancer and pathological values of C-reactive protein, while no correlation was found with the site of tumour. NRS was negatively associated with QoL (P gastric cancer malnutrition is frequent at diagnosis and this is likely due to reduction in food intake. Moreover, NRS is directly correlated with tumour stage and inversely correlated with QoL, which makes it a useful tool to identify patients in need of an early nutritional intervention during oncological treatments.

    Prostate tumor overexpressed 1 (PTOV1) was demonstrated to play an important role in cancer progression and was correlated with unfavorable clinical outcome. However, the clinical role of PTOV1 in cancer remains largely unknown. This study aimed to investigate the expression and clinicopathological significance of PTOV1 in breast cancer. The mRNA and protein expression levels of PTOV1 were analyzed in 12 breast cancer cell lines and eight paired breast cancer tumors by semi-quantitative real time-PCR and western blotting, respectively. Immunohistochemistry was performed to assess PTOV1 protein expression in 169 paraffin-embedded, archived breast cancer samples. Survival analysis and Cox regression analysis were performed to investigate the clinicopathological significance of PTOV1 expression. Our data revealed that PTOV1 was frequently overexpressed in breast cancer cell lines compared to normal human breast epithelial cells and in primary breast cancer samples compared to adjacent noncancerous breast tissues, at both the mRNA and protein levels. Moreover, high expression of PTOV1 in breast cancer is strongly associated with clinicopathological characteristics and estrogen receptor expression status (P = 0.003). Breast cancer patients with higher PTOV1 expression had substantially shorter survival times than patients with lower PTOV1 expression (P < 0.001). Univariate and multivariate analysis revealed that PTOV1 might be an independent prognostic factor for breast cancer patients (P = 0.005). Our study showed that PTOV1 is upregulated in breast cancer cell lines and clinical samples, and its expression was positively associated with progression and aggressiveness of breast cancer, suggesting that PTOV1 could serve as an independent prognostic marker

    Accurate staging of rectal cancer remains essential for optimal patient selection for combined modality treatment, including radiotherapy, chemotherapy and surgery. We aimed at examining the correlation of cell free DNA with the pathologic stage and subsequent risk of recurrence for patients with locally advanced rectal cancer undergoing preoperative chemoradiation. We examined 75 patients with locally advanced rectal cancer receiving preoperative chemoradiation. Blood samples for translational use were drawn prior to rectal surgery. The level of cell free DNA was quantified by digital droplet PCR and expressed as copy number of beta 2 microglobulin. We found a median level of cell free DNA in the AJCC stages I-III of 3100, 8300, and 10,700 copies/mL respectively. For patients with 12 sampled lymph nodes or above, the median level of cell free DNA were 2400 copies/mL and 4400 copies/mL (p = 0.04) for node negative and node positive disease respectively. The median follow-up was 39 months and 11 recurrences were detected (15%). The median level for patients with recurrent disease was 13,000 copies/mL compared to 5200 copies/mL for non-recurrent patients (p = 0.08). We have demonstrated a correlation between the level of total cell free DNA and the pathologic stage and nodal involvement. Furthermore, we have found a trend towards a correlation with the risk of recurrence following resection of localized rectal cancer.

    Obesity is one of the most challenging problems in human health and is recognized as an important risk factor for many chronic diseases. It remains unclear how the neural systems (e.g., the mesolimbic "reward" and the prefrontal "control" neural systems) are correlated with patients' executive function (EF), conceptualized as the integration of "cool" EF and "hot" EF. "Cool" EF refers to relatively abstract, non-affective operations such as inhibitory control and mental flexibility. "Hot" EF refers to motivationally significant affective operations such as affective decision-making. We tried to find the correlation between structural and functional neuroimaging indices and EF in obese patients. The study population comprised seventeen patients with obesity (seven males and 10 females, BMI = 37.99 ± 5.40, age = 31.82 ± 8.75 year-old) preparing to undergo bariatric surgery. We used noninvasive diffusion tensor imaging, generalized q-sampling imaging, and resting-state functional magnetic resonance imaging to examine the neural correlations between structural and functional neuroimaging indices and EF performances in patients with obesity. We reported that many brain areas are correlated to the patients' EF performances. More interestingly, some correlations may implicate the possible associations of EF and the incentive motivational effects of food. The neural correlation between the left precuneus and middle occipital gyrus and inhibitory control may suggest that patients with a better ability to detect appetitive food may have worse inhibitory control. Also, the neural correlation between the superior frontal blade and affective decision-making may suggest that patients' affective decision-making may be associated with the incentive motivational effects of food. Our results provide evidence suggesting neural correlates of EF in patients with obesity.

    Hope is an important coping resource for cancer patients. Types and sources of hope and hope- inspiring strategies are not well investigated among Iranian cancer patients. The aims of present study were therefore to investigate the nature of hope and some demographic predictors of hope among Iranian cancer patients. This descriptive-correlational study was undertaken among 200 cancer patients admitted to an educational center affiliated to Ardabil University of Medical Sciences, Iran. Participants were selected using a convenience sampling method. The Herth Hope Index and other validated questionnaires were used to investigate level of hope and types and sources of hope, as well as hope-inspiring strategies. Data were analyzed using SPSS statistical software. The overall score for hope was 31 from total scores ranging between 12 and 48. Some 94% of patients mentioned 'return to normal life' and 'complete healing of disease by drugs and physicians' as their main hopes. The most important sources of hope reported by patients include spiritual resources, family members, healthcare workers, and medicines and treatments available for the disease. Relationship with God, praying/blessing, controlling the signs and symptoms of the disease, and family/health care workers' support were the main hope-inspiring strategies. Patients who had a history of metastasis, or who were older, illiterate, divorced/widowed and lived with their children reported lower levels of hope. On the other hand, employed patients and those with good support from their families had higher levels of hope. The study findings showed moderate to high levels of hope among Iranian cancer patients. Accordingly, the role of spiritual/religion, family members and health care workers should be considered in developing care plans for these patients.

    Cancers are among the leading causes of morbidity and mortality worldwide, and the number of new cases is expected to rise significantly over the next decades. At the same time, all types of cancer treatment, such as surgery, radiation therapy, and pharmacological therapies are improving in sophistication, precision and in the power to target specific characteristics of individual cancers. Thus, while many cancers may still not be cured they may be converted to chronic diseases. All of these treatments, however, are impeded or precluded by the frequent development of malnutrition and metabolic derangements in cancer patients, induced by the tumor or by its treatment. These evidence-based guidelines were developed to translate current best evidence and expert opinion into recommendations for multi-disciplinary teams responsible for identification, prevention, and treatment of reversible elements of malnutrition in adult cancer patients. The guidelines were commissioned and financially supported by ESPEN and by the European Partnership for Action Against Cancer (EPAAC), an EU level initiative. Members of the guideline group were selected by ESPEN to include a range of professions and fields of expertise. We searched for meta-analyses, systematic reviews and comparative studies based on clinical questions according to the PICO format. The evidence was evaluated and merged to develop clinical recommendations using the GRADE method. Due to the deficits in the available evidence, relevant still open questions were listed and should be addressed by future studies. Malnutrition and a loss of muscle mass are frequent in cancer patients and have a negative effect on clinical outcome. They may be driven by inadequate food intake, decreased physical activity and catabolic metabolic derangements. To screen for, prevent, assess in detail, monitor and treat malnutrition standard operating procedures, responsibilities and a quality control process should be established at each

    The total number of malignant neoplasms included on this study 7,787 cases(10.4%) among 74,928 cases for 2 years. On sex, females with 57.6% were much more than males with 42.4%. The highest proportion of cancer 50-59 age group. The most frequent primary site among males was found to be stomach with 36.2%, followed by liver(12.3%), lung(12.2%), esophagus(15.5%) and larynx(4.9%). In females, the first order was uterine cervix with 47.3%, followed most common type of morphology of malignant neoplasms was adenocarcinoma(39.0%) in males an squamous cell carcinoma(56.2%) in females. Among the cancer patients initially diagnosed in this hospital, the proportion of malignant neoplasms by the extent of disease was 4.6% for patient with carcinoma-in-situ, 76.3% for patients with localized involvement, 11.6% for patients with regional involvement and 7.5% for patients with distant involvement. Among,the cancer patients initially treatment in this hospital, the proportion of malignant neoplasms by the method of treatment was 19.0% for surgery, 27.7 for radiotherapy and 24.2% for chemotherapy. Among the cancer patients confirmed by medical records, 11.2% was traced more than 5 years. (Author)

    To enable better psychosocial, informational, and practical support of Chinese patients with cancer, this study was conducted to identify the specific support needs of Chinese immigrant cancer patients. The Cancer Portal Project at Memorial Sloan-Kettering Cancer Center's Center for Immigrant Health and Cancer Disparities is a patient navigation program that assists underserved and minority cancer patients in obtaining social and economic assistance at ten New York City cancer clinics. This need assessment was conducted as part of the Portal Project. Sixty-four questions were added to the existing Portal Intake Form about the needs and preferences for Chinese-language support and survivorship services. Descriptive analysis was performed, as well as an exploratory principal component's factor analysis to determine if there were any patterns in the services and programs in which patients were interested. Ninety-six patients were approached for participation; 59 agreed to participate. Eighty-eight percent of participants were born in China. Ninety-seven percent preferred to speak Mandarin, Cantonese, or Fujianese in the healthcare setting. When asked about general interest in support programs, 53 % of the participants were "very interested," 27 % were "maybe interested," and 17 % were "not interested." Programs in which more participants were "very interested" included those that would provide information about obtaining financial assistance (79 %) and social assistance (74 %), information on treatment options (67 %), help in coping with the burden of illness on the family (65 %), and information about general healthcare (63 %). The factor analysis resulted in the identification of five factors: social/financial/treatment and care issues, nutrition and exercise/networking/general health care, coping with fear and stress, herbs and dietary supplements, and acupuncture and acupressure. In this study, 80 % of the participants expressed interest in programs tailored for

    We present a retrospective case series of patients with hyperthyroidism and thyroid cancer. Our goal was to look at their clinical characteristics and outcomes to determine which patients would require further investigation. We reviewed the case notes of all patients with a histopathologic diagnosis of thyroid cancer and biochemical evidence of hyperthyroidism who had been treated at a thyroid cancer center from January 2006 through October 2013. During that time, 66 patients had been diagnosed with thyroid cancer. Of these, 8 patients (12%)-all women, aged 29 to 87 years (mean: 55.6; median: 50.5)-had biochemical evidence of hyperthyroidism. Among these 8 patients, 4 had an autonomously functioning toxic nodule (AFTN), 3 were diagnosed with Graves disease, and 1 had a toxic multinodular goiter. Five patients had suspicious features on preoperative ultrasonography. All 8 patients were diagnosed with the papillary type of thyroid carcinoma. The mean size of the tumor in the 4 patients with AFTN was significantly larger than it was in those with Graves disease (42.3 ± 23.8 mm vs. 3.8 ± 1.6; p = 0.04). The 3 patients with Graves disease all had incidentally found papillary microcarcinoma. Between these two groups, the patients with AFTN had a poorer prognosis; 2 of them had extracapsular invasion and lymph node metastasis, and another died of her disease. We found that the incidence of hyperthyroidism in thyroid cancer patients was relatively high (12%). In contrast to what has previously been reported in the literature, patients with AFTN seem to have more aggressive disease and poorer outcomes than do patients with Graves disease. Any suspicious nodule associated with hyperthyroidism should be evaluated carefully.

    To evaluate the relevance, performance and potential usefulness of the Patient Assessment of cancer Communication Experiences (PACE) items. Items focusing on specific communication goals related to exchanging information, fostering healing relationships, responding to emotions, making decisions, enabling self-management, and managing uncertainty were tested via a retrospective, cross-sectional survey of adults who had been diagnosed with cancer. Analyses examined response frequencies, inter-item correlations, and coefficient alpha. A total of 366 adults were included in the analyses. Relatively few selected Does Not Apply, suggesting that items tap relevant communication experiences. Ratings of whether specific communication goals were achieved were strongly correlated with overall ratings of communication, suggesting item content reflects important aspects of communication. Coefficient alpha was ≥.90 for each item set, indicating excellent reliability. Variations in the percentage of respondents selecting the most positive response across items suggest results can identify strengths and weaknesses. The PACE items tap relevant, important aspects of communication during cancer care, and may be useful to cancer care teams desiring detailed feedback. The PACE is a new tool for eliciting patients' perspectives on communication during cancer care. It is freely available online for practitioners, researchers and others.

    Objective : To investigate the relationship between the perfusion CT features and the clinicopathologically determined prognostic factors in advanced gastric cancer cases. Materials and Methods : A perfusion CT was performed on 31 patients with gastric cancer one week before surgery using a 16-channel multi-detector CT (MDCT) instrument. The data were analyzed with commercially available software to calculate tumor blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS). The microvessel density (MVD), was evaluated by immunohistochemical staining of the surgical specimens with anti-CD34. All of the findings were analyzed prospectively and correlated with the clinicopathological findings, which included histological grading, presence of lymph node metastasis, serosal involvement, distant metastasis, tumor, node, metastasis (TNM) staging, and MVD. The statistical analyses used included the Student's t-test and the Spearman rank correlation were performed in SPSS 11.5. Result : The mean perfusion values and MVD for tumors were as follows: BF (48.14+/-16.46 ml/100 g/min), BV (6.70+/-2.95 ml/100 g), MTT (11.75+/-4.02 s), PS (14.17+/-5.23 ml/100 g/min) and MVD (41.7+/-11.53). Moreover, a significant difference in the PS values was found between patients with or without lymphatic involvement (p = 0.038), as well as with different histological grades (p 0.04) and TNM stagings (p = 0.026). However, BF, BV, MTT, and MVD of gastric cancer revealed no significant relationship with the clinicopathological findings described above (p > 0.05). Conclusion : The perfusion CT values of the permeable surface could serve as a useful prognostic indicator in patients with advanced gastric cancer

    Objective : To investigate the relationship between the perfusion CT features and the clinicopathologically determined prognostic factors in advanced gastric cancer cases. Materials and Methods : A perfusion CT was performed on 31 patients with gastric cancer one week before surgery using a 16-channel multi-detector CT (MDCT) instrument. The data were analyzed with commercially available software to calculate tumor blood flow (BF), blood volume (BV), mean transit time (MTT), and permeability surface (PS). The microvessel density (MVD), was evaluated by immunohistochemical staining of the surgical specimens with anti-CD34. All of the findings were analyzed prospectively and correlated with the clinicopathological findings, which included histological grading, presence of lymph node metastasis, serosal involvement, distant metastasis, tumor, node, metastasis (TNM) staging, and MVD. The statistical analyses used included the Student's t-test and the Spearman rank correlation were performed in SPSS 11.5. Result : The mean perfusion values and MVD for tumors were as follows: BF (48.14+/-16.46 ml/100 g/min), BV (6.70+/-2.95 ml/100 g), MTT (11.75+/-4.02 s), PS (14.17+/-5.23 ml/100 g/min) and MVD (41.7+/-11.53). Moreover, a significant difference in the PS values was found between patients with or without lymphatic involvement (p = 0.038), as well as with different histological grades (p 0.04) and TNM stagings (p = 0.026). However, BF, BV, MTT, and MVD of gastric cancer revealed no significant relationship with the clinicopathological findings described above (p > 0.05).

    Full Text Available Antibodies to leukemia differentiation factor (HLDF in patients with gastrointestinal cancer Abstract. Patients with gastric cancer exhibit higher levels of IgG4-antibodies to human leukemia differentiation factor (HLDF, as compared with healthy individuals, whereas, in patients with colorectal cancer, one may detect high levels of IgA anti-HDLF antibodies, along with lower levels of IgG1 class antibodies against HLDF than in control group. Among patients with gastrointestinal cancer, a positive correlation is revealed between contents of highly differentiated cells in the tumor, and IgM antibodies to HDLF. Meanwhile, a reverse relationship is noted between low differentiation of tumor cells and levels of IgG2 antibodies to HDLF in gastric cancer patients, or IgG3 antibodies to HDLF in patients with colorectal cancer.

    The results and problems of radiotherapy were analyzed in 57 lung cancer patients more than 65 years of age (average age: 74.8 years). Of these, 45 (79%) were irradiated with a total dose exceeding 40 Gy. In these patients, the median survival was 13 months for Stages I and II, 6.5 months for Stage III, and 5 months for Stage IV. The results of combined radiotherapy and chemotherapy were better than those of radiotherapy alone. Also, slightly better results were obtained in patients treated with split-course than continuous-course irradiation. In aged lung cancer patients the prognosis was highly influenced by their respiratory function. Double cancers were present in 9 (16%) of the 57 patients. (author)

    To determine the frequency of granulomatous inflammation on histopathological findings amongst cancer patients and correlating them with tuberculosis. Methods: The retrospective review was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised medical records of cancer patients with a histopathological finding of granulomatous inflammation between January 2010 and December 2015. Data was reviewed, including clinical history, availability of acid fast bacilli stain on tissue and mycobacterium tuberculosis culture results. Data related to treatment, duration and outcomes was also reviewed and was analysed using SPSS 19. Results: Out of 28690 cancer patients during the study period, 17345(60.4%) had undergone biopsy for different reasons, and of those, 78 (0.45%) had granulomatous inflammation and formed the study sample. Among them, 40(51.3%) patients had caseous granulomatous inflammation while 38 (48.7%) had non-caseous granulomas. Acid fast bacillus tissue stain was performed on 77(98.7%) patients, of whom only 9 (11.5%) specimens showed acid fast bacilli. Mycobacterium tuberculosis culture was performed on 53(68%) specimens and among them 13(16.7%) grew mycobacterium tuberculosis. Anti-tuberculosis treatment was offered to 38 (48.7%) patients, including those with positive AFB stain and MTB culture results. Of them, 32(41%) patients completed the treatment while 4(5.1%) defaulted and 2(2.6%) died. Symptomatic and radiological improvement was observed in 16(20.5%) patients. Conclusion: Granulomatous inflammation was infrequently encountered in cancer patients. Mycobacterium tuberculosis cultures assisted in definitive decision-making but granulomatous inflammation could not be anticipated when the specimens were initially processed except when visible caseation was encountered. Processing specimens for mycobacterium tuberculosis cultures when caseation was encountered may be a reasonable strategy to adopt. (author)

    Morbid obesity is a known risk factor for the development of endometrial cancer. Several studies have demonstrated the overall feasibility of robotic-assisted surgical staging for endometrial cancer as well as the benefits of robotics compared with laparotomy. However, there have been few reports that have evaluated robotic surgery for endometrial cancer in the supermorbidly obese population (body mass index [BMI], ≥50 kg/m(2)). We sought to evaluate safety, feasibility, and outcomes for supermorbidly obese patients who undergo robotic surgery for endometrial cancer, compared with patients with lower body mass indices. We performed a retrospective chart review of 168 patients with suspected early-stage endometrial adenocarcinoma who underwent robotic surgery for the management of their disease. Analysis of variance and univariate logistic regression were used to compare patient characteristics and surgical variables across all body weights. Cox proportional hazard regression was used to determine the impact of body weight on recurrence-free and overall survival. The mean BMI of our cohort was 40.9 kg/m(2). Median follow up was 31 months. Fifty-six patients, 30% of which had grade 2 or 3 tumors, were supermorbidly obese with a BMI of ≥50 kg/m(2) (mean, 56.3 kg/m(2)). A comparison between the supermorbidly obese and lower-weight patients demonstrated no differences in terms of length of hospital stay, blood loss, complication rates, numbers of pelvic and paraaortic lymph nodes retrieved, or recurrence and survival. There was a correlation between BMI and conversion to an open procedure, in which the odds of conversion increased with increasing BMI (P = .02). Offering robotic surgery to supermorbidly obese patients with endometrial cancer is a safe and feasible surgical management option. When compared with patients with a lower BMI, the supermorbidly obese patient had a similar outcome, length of hospital stay, blood loss, complications, and numbers of lymph

    Complete text of publication follows. Objective. The aim of this study was to examine and further clarify the extent of radon and progeny induced carcinogenesis, both separated from and combined with other confounders and health risk factors. This work was financed by National Development Agency, Hungary, with GVOP-3.1.1.-2004-05-0384/3.0. Methods. A case-control study was conducted in a Hungarian countryside region where the proportion of houses with yearly average radon level above 200 Bq.m -3 was estimated to be higher than 20% by our preceding regional surveys. Radon levels were measured with CR39 closed etched detectors for three seasons separately yielding yearly average by estimating the low summer level. The detectors were placed in the bedrooms, where people were expected to spend one third of a day. 520 patients with diagnosed cancers were included in these measurements, amongst which 77 developed lung or respiratory cancers. The control group consisted 6333 individuals, above 30 years of age. Lifestyle risk factors of cancers were collected by surveys including social status, pollution from indoor heating, smoking and alcohol history, nutrition, exercise and mental health index 5. Except smoking and alcohol habits, these cofactors were only available for the control group. Comparing disease occurrences the authors selected the multivariate generalised linear models. The case and control proportions along a given factor are binomially distributed, thus the logit link function was used. For radon both log and linear terms were probed for. Results. Many known health confounders of cancers correlated with radon levels, with an estimated total net increase of 50-150 Bq m -3 with increased risks. For lung cancers the model with the terms radon, age, gender and smoking was found to have the lowest Akaike Information Criterion (AIC). Heavy dependency on age, gender and smoking contribute largely to observed lung cancer incidence. However log linear relationship

    Purpose: To analyze the toxicity of uniform scanning proton therapy for lung cancer patients and its correlation with dose distribution. Methods: In this study, we analyzed the toxicity of 128 lung cancer patients, including 18 small cell lung cancer and 110 non small cell lung cancer patients. Each patient was treated with uniform scanning proton beams at our center using typically 2–4 fields. The prescription was typically 74 Cobalt gray equivalent (CGE) at 2 CGE per fraction. 4D Computerized Tomography (CT) scans were used to evaluate the target motion and contour the internal target volume, and repeated 3 times during the course of treatment to evaluate the need for plan adaptation. Toxicity data for these patients were obtained from the proton collaborative group (PCG) database. For cases of grade 3 toxicities or toxicities of interest such as esophagitis and radiation dermatitis, dose distributions were reviewed and analyzed in attempt to correlate the toxicity with radiation dose. Results: At a median follow up time of about 21 months, none of the patients had experienced Grade 4 or 5 toxicity. The most common adverse effect was dermatitis (81%: 52%-Grade 1, 28%-Grade 2, and 1% Grade 3), followed by fatigue (48%), Cough (46%), and Esophagitis (45%), as shown in Figure 1. Severe toxicities, such as Grade 3 dermatitis or pain of skin, had a clear correlation with high radiation dose. Conclusion: Uniform scanning proton therapy is well tolerated by lung cancer patients. Preliminary analysis indicates there is correlation between severe toxicity and high radiation dose. Understanding of radiation resulted toxicities and careful choice of beam arrangement are critical in minimizing toxicity of skin and other organs.

    Purpose: To compare the correlations between different dosimetric indices derived from the pharyngeal constrictor muscles and proximal esophagus with patient-reported difficulty in swallowing 6 months post radiotherapy using a novel patient reported outcome version of CTCAE (PRO-CTCAE). Methods: Forty-three patients with oropharyngeal squamous cell carcinoma were treated on a prospective multi-institutional study. All patients received de-intensified 60 Gy intensity modulated radiotherapy. We investigated correlations of individual patient dosimetric data of the superior (SPC), middle (MPC), inferior (IPC) pharyngeal constrictor muscles, the superior esophagus (SES), and the inferior esophagus (IES) to their self-reported 6 month post-treatment swallowing difficulty responses. Mild (≥ Grade 1) swallowing difficulty responses were used as the clinical endpoint indicating response. The predictive efficacy of Dmean and dose-volume (VD) points were assessed through the area under the Receiver Operating Characteristic curve (ROC) and Odds Ratio (OR). Results: The SES and SPC had more favorable area under the curves (AUC) for the Dmean (0.62 and 0.70) while the Dmean to the IPC, MPC, and IES produced suboptimal AUCs (0.42, 0.48, and 0.52). Additionally, over the range of VD, the V54 and V55 for the SES and SPC demonstrated the highest AUCs: AUC(SES) = 0.76–0.73 and AUC(SPC) = 0.72–0.69, respectively. The IES, IPC, and MPC had worse AUC results over the range of VD. An optimal OR can be found when V54 = 96% for the SPC, where OR = 3.96 (1.07–14.62). Conclusion: The V45 and V55 of the SES and SPC had the highest correlation to the clinical endpoint compared to the commonly used dosimetric index, Dmean for both the esophagus and constrictor muscles. The reported dosimetric data demonstrates that new dosimetric indices may need to be considered in the setting of dose de-escalation and self-reported outcomes.

    Full Text Available BACKGROUND Breast Cancer is the most common female cancer worldwide and carries significant psychosocial morbidity. The diagnosis of the disease and the treatment modalities like surgery and chemotherapy contribute to the morbidity. The recognition of the psychosocial morbidity associated with mastectomy can help us formulate effective counselling strategies. The objectives of this study were- to assess the psychosocial morbidity in patients undergoing mastectomy for carcinoma breast, to identify the preoperative variables that predict the morbidity and to find out the correlation between degree of neuroticism of the individual and morbidity. MATERIALS AND METHODS 35 female patients who had mastectomy for breast cancer were evaluated at three time-points, preoperatively, immediately after surgery and 2 months after surgery. Anxiety and depression was assessed using Hospital Anxiety and Depression Scale (HADS, psychological distress was measured using General Health Questionnaire (GHQ-12 and neuroticism was assessed by Eysenck Personality Inventory Neuroticism subscale (EPI-N. RESULTS There was a high level of anxiety, depression and GHQ scores preoperatively with a further worsening of these over the three interviews. Age, marital status and menopausal status were factors which had an influence on psychosocial morbidity. Preoperative EPI-N scores positively correlated with psychosocial morbidity. CONCLUSION There is a high level of psychosocial morbidity in patients undergoing mastectomy for breast cancer and mastectomy seems to worsen it in the first two months after surgery. Our study shows that psychosocial morbidity is affected by age, marital status, menopausal status and level of neuroticism.

    In the last 9 years, 217 patients with prostate cancer were treated at our department. Of these patients 153 cases treated by estrogen therapy were followed up by bone scintigraphy and tumor marker examinations (prostate specific antigen [PSA], prostate acid phosphatase [PAP], gamma-seminoprotein [γ-SM) . The correlation between changes on bone scintigrams and synchronous changes in tumor markers was evaluated retrospectively. In cases in which bone metastasis was not recognized on bone scintigrams before treatment, changes of tumor markers corresponded with subsequent changes on bone scintigrams in more than 90%. However, in cases with bone metastasis on bone scintigrams before treatment, changes of bone scintigrams and changes of tumor markers corresponded in only 55% of cases. Changes of bone scintigrams do not always correspond with changes of tumor markers. However, by taking into consideration physical examination parameters such as bone pain, in addition to changes of tumor markers, most changes on bone scintigrams can be anticipated. The reasons for lack of correspondence between changes of bone scintigrams and changes of tumor markers may be, changes of tumor markers are more rapid than the changes on bone scintigram, some poorly differentiated cancers do not have increased tumor marker levels and bone scintigrams do not demonstrate soft tissue involvement. In the follow-up of patients with prostate cancer, it is not necessary to perform bone scintigraphy regularly at 3-month intervals. Bone scintigraphy should only be performed when serum levels of tumor markers increase or bone pain appears. (author)

    Full Text Available Most cancer patients often neglect the possibility of secondary cancer. Colorectal cancer (CRC is the third leading cause of cancer death in Taiwan. It is important to be aware of the clinical characteristics of double cancer in CRC patients for early diagnosis and treatment. We retrospectively analyzed 1,031 CRC patients who underwent surgical treatment at the Department of Surgery of Kaohsiung Medical University Hospital between January 1998 and December 2004. Among these patients, CRC was accompanied by cancer of other organs in 17 patients (1.65%, either synchronously or metachronously. Therefore, we describe our experience regarding the location of CRC, the clinical symptoms and signs of these patients, the TNM stage, histology, phase, association with other malignancies, interval between cancers and clinical outcomes. Of the 17 patients in whom CRC was accompanied by primary cancer of other organs, there were four synchronous and 13 metachronous multiple cancer patients. Our patient group comprised six men and 11 women with ages ranging from 47 to 88 years (median age, 66 years. The most common location of CRC was the sigmoid colon. Six gastric cancers (35.2% and six breast cancers (35.2% were associated with primary CRC. The remaining six second primary cancers were one lung cancer, one thyroid cancer, one cervical cancer, one ovarian cancer, one skin cancer, and one urinary bladder cancer. Of the 13 metachronous multiple cancer patients, eight patients developed subsequent CRC after primary cancers of other organs, whereas two patients developed a subsequent second primary cancer after CRC. The intervals between the development of metachronous multiple cancers ranged from 2 to 19 years. In this retrospective analysis, breast and gastric cancer patients were at increased risk of developing subsequent secondary CRC. Careful attention should always be paid to the possibility of secondary CRC in treating these cancer patients. Cancer

    To assess the rheological changes in haematological and non-haematological cancer patients pre and post chemotherapy. It is a prospective study of 50 patients comprising 16(32%) haematological and 34(68%) non-haematological cancers of various types from March to December 2005 at University of Benin Teaching Hospital, Nigeria. Rheologic parameters estimated by the various specific diagnostic methods were determined in cancer patient's pre and post chemotherapy. The rheological tests estimated were relative plasma viscosity (RPV) measured by means of a capillary viscometer, whole blood viscosity (WBV), erythrocyte sedimentation rate (ESR) and plasma fibrinogen concentration (PFC) estimated by the Ingram's Clot weight method. The RPV in pre chemotherapy (p=0.006) and WBV in post chemotherapy (p=0.0231) patients measured revealed a significant difference when compared to controls. The fibrinogen concentration (P<0.0001) and ESR values (P<0.0001) were significantly increased in cancer patients when compared to controls. We conclude that total reduction of hyperviscosity and hyperfibrinogenaemia may contribute to effective treatment strategies in cancer patients. (author)

  20. Fertility preservation in young cancer patients

    Full Text Available As a result of advances in treatment, almost 80% of children and adolescents who receive a diagnosis of cancer become long-term survivors. The increased survival rate of children and adolescents with cancer has resulted in a major interest in the long-term effects of cancer treatment on the possibility for future fertility. Currently established methods for the preservation of fertility are available only for pubertal males and females. Pubertal male cancer patients should be encouraged to freeze numerous sperm samples even when sperm count and motility are poor. In these cases, intracytoplasmic sperm injection is a powerful technique compared with intrauterine insemination since thawed sperm samples with poor parameters can produce relatively high fertilization rates resulting in normal pregnancies and deliveries. Married pubertal women should be proposed ovulation induction, follicular aspiration, and fertilization with husband sperm. Single women could benefit from vitrification of oocytes. This requires a delay of about 3 weeks in the commencement of chemotherapy to enable follicular growth. Fertility preservation for prepubertal patients is more of a problem. Young girls could be offered cryopreservation of gametes in the gonadal tissue. Cryopreservation of testicular tissue was suggested for fertility preservation for young boys, but this method is totally experimental and not currently offered. Discussing future fertility is part of the consultation of young female and male patients facing potentially gonadotoxic cancer therapy. It is the role of reproductive specialists to create various options in their laboratory to preserve fertility potential of cancer patients.

    Patients with esophageal cancer have a poor prognosis because they often have no symptoms until their disease is advanced.There are no screening recommendations for patients unless they have Barrett's esophagitis or a significant family history of this disease.Often,esophageal cancer is not diagnosed until patients present with dysphagia,odynophagia,anemia or weight loss.When symptoms occur,the stage is often stage Ⅲ or greater.Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection.The treatment of patients who have locally advanced esophageal cancer is more complex and controversial.Despite multiple trials,treatment recommendations are still unclear due to conflicting data.Sadly,much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically.Additionally,studies have been underpowered or stopped early due to poor accrual.In the United States,concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient.Patients who have metastatic disease are treated palliatively.The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer,and to review the literature which guides our treatment recommendations.

    CONCLUSION: This study shows that patients who are less depressed have higher levels of resilience and that psychological resilience may independently contribute to lower levels of depression among breast cancer patients. The level of psychological resilience may be a protective factor for depression and psychological distress.

    Approximately two thirds of all Dutch cancer patients have severe emotional problems; shortly after their change from the treatment regime into the regime of medical controls. Half of them even need professional support. It is, therefore, important that a professional listens with empathy to the patient's version of the illness story. Story telling helps to overcome the existential crisis of being a cancer patient; it is an essential step in the revalidation process. Themes and open questions which structure the communication are suggested in this article.

    To present the ways in which race, ethnicity, class, gender, and sexual orientation interact in the context of cancer risk, access to care, and treatment by health care providers. Cancer risk factors, access to care, and treatment for lesbian, gay, bisexual, and transgender (LGBT) patients are discussed within the context of intersectionality and cultural humility. Peer reviewed articles, cancer organizations, and clinical practice. LGBT patients have multiple identities that intersect to create unique experiences. These experiences shape their interactions with the health care system with the potential for positive or negative consequences. More data is needed to describe the outcomes of those experiences and inform clinical practice. Oncology nurses have an obligation to acknowledge patients' multiple identities and use the practice of cultural humility to provide individualized, patient-centered care.

    2012-04-01

    Taste dysfunction is a significant but underestimated issue for patients with cancer. Impaired taste results in changes in diet and appetite, early satiety, and impaired social interactions. Nurses can play a key role in educating patients and families on the pathophysiology of taste dysfunction by suggesting interventions to treat the consequences of taste dysfunction, when available, and offering psychosocial support as patients cope with this often devastating consequence of treatment. Taste recognition helps humans identify the nutritional quality of food and signals the digestive tract to begin secreting enzymes. Spoiled or tainted foods typically are recognized by their bad taste. Along with the other sensory systems, taste is crucial for helping patients treated for cancer feel normal. This article will review the anatomy and physiology of taste; define the different types of taste dysfunction, including the underlying pathophysiologic basis related to cancer treatment; and discuss potential nursing interventions to manage the consequences of taste dysfunction.

    To determine whether a correlation exists between maximum standardized uptake value (SUV{sub max}) on {sup 18}F-fluorodeoxyglucose positron emission tomography (FDG-PET) and the subtypes of breast cancer. This retrospective study involved 548 patients (mean age 51.6 years, range 21-81 years) with 552 index breast cancers (mean size 2.57 cm, range 1.0-14.5 cm). The correlation between {sup 18}F-FDG uptake in PET/CT, expressed as SUV{sub max}, and immunohistochemically defined subtypes (luminal A, luminal B, human epidermal growth factor receptor 2 (HER2) positive and triple negative) was analyzed. The mean SUV{sub max} value of the 552 tumours was 6.07 ± 4.63 (range 0.9-32.8). The subtypes of the 552 tumours were 334 (60 %) luminal A, 66 (12 %) luminal B, 60 (11 %) HER2 positive and 92 (17 %) triple negative, for which the mean SUV{sub max} values were 4.69 ± 3.45, 6.51 ± 4.18, 7.44 ± 4.73 and 9.83 ± 6.03, respectively. In a multivariate regression analysis, triple-negative and HER2-positive tumours had 1.67-fold (P < 0.001) and 1.27-fold (P = 0.009) higher SUV{sub max} values, respectively, than luminal A tumours after adjustment for invasive tumour size, lymph node involvement status and histologic grade. FDG uptake was independently associated with subtypes of invasive breast cancer. Triple-negative and HER2-positive breast cancers showed higher SUV{sub max} values than luminal A tumours. circle {sup 18} F-FDG PET demonstrates increased tissue glucose metabolism, a hallmark of cancers.

    Highlights: • Gastric cancers’ ADC values were significantly lower than normal gastric wall. • Gastric adenocarcinomas with different differentiation had different ADC values. • Gastric adenocarcinomas’ ADC values correlated with histologic differentiations. • Gastric cancers’ ADC values correlated with Lauren classifications. • Mean ADC value was better than min ADC value in characterizing gastric cancers. - Abstract: Objective: The purpose of this study was to evaluate the correlations between histological differentiation and Lauren classification of gastric cancer and the apparent diffusion coefficient (ADC) value of diffusion weighted imaging (DWI). Materials and methods: Sixty-nine patients with gastric cancer lesions underwent preoperative magnetic resonance imaging (MRI) (3.0T) and surgical resection. DWI was obtained with a single-shot, echo-planar imaging sequence in the axial plane (b values: 0 and 1000 s/mm 2 ). Mean and minimum ADC values were obtained for each gastric cancer and normal gastric walls by two radiologists, who were blinded to the histological findings. Histological type, degree of differentiation and Lauren classification of each resected specimen were determined by one pathologist. Mean and minimum ADC values of gastric cancers with different histological types, degrees of differentiation and Lauren classifications were compared. Correlations between ADC values and histological differentiation and Lauren classification were analyzed. Results: The mean and minimum ADC values of gastric cancers, as a whole and separately, were significantly lower than those of normal gastric walls (all p values <0.001). There were significant differences in the mean and minimum ADC values among gastric cancers with different histological types, degrees of differentiation and Lauren classifications (p < 0.05). Mean and minimum ADC values correlated significantly (all p < 0.001) with histological differentiation (r = 0.564, 0.578) and Lauren

    Combined PET/MRI systems are now commercially available and are expected to change the medical imaging field by providing combined anato-metabolic image information. We believe this will be of particular relevance in imaging of cancer patients. At the Department of Clinical Physiology, Nuclear...... described include brain tumors, pediatric oncology as well as lung, abdominal and pelvic cancer. In general the cases show that PET/MRI performs well in all these types of cancer when compared to PET/CT. However, future large-scale clinical studies are needed to establish when to use PET/MRI. We envision...... that PET/MRI in oncology will prove to become a valuable addition to PET/CT in diagnosing, tailoring and monitoring cancer therapy in selected patient populations....

    The majority of squamous cell carcinomas of cervix are preceded by visible changes in the cervix, most often detected by cervical smear. As cervical cancer is preceded by long precancerous stages, identification of the high-risk population through detection of DNA ploidy may be of importance in effective management of this disease. Here we attempted to correlate aneuploidy DNA patterns and their influence on biological behavior of flow-cytometry analysis of DNA ploidy which was carried out in cytologically diagnosed cases of mild (79), moderate (36), and severe (12) dysplasia, as well as “atypical squamous cells of unknown significance (ASCUS)” (57) along with controls (69), in order to understand its importance in malignant progression of disease. Cytologically diagnosed dysplasias, which were employed for DNA ploidy studies, 39 mild, 28 moderate, and 11 severe dysplasia cases were found to be aneuploidy. Out of the 69 control subjects, 6 cases showed aneuploidy pattern and the rest 63 subjects were diploid. An aneuploidy pattern was observed in 8 out of 57 cases of cytologically evaluated ASCUS. The results of the followup studies showed that aberrant DNA content reliably predicts the occurrence of squamous cell carcinoma in cervical smear. Flow cytometric analysis of DNA ploidy may provide a strategic diagnostic tool for early detection of carcinoma cervix. Therefore, it is a concept of an HPV screening with reflex cytology in combination with DNA flow cytometry to detect progressive lesions with the greatest possible sensitivity and specificity.

    In this retrospective study we reviewed the volume and modality of hydration of consecutive series of terminal cancer patients in two different settings. In a palliative care unit 203/290 admitted patients received subcutaneous hydration for 12 +/- 8 days at a daily volume of 1015 +/- 135 ml/day. At the cancer center, 30 consecutive similar patients received intravenous hydration for 11.5 +/- 5 days (P > 0.2) but at a daily volume of 2080 +/- 720 ml/day (P palliative care unit patients required discontinuation of hydration because of complications. Hypodermoclysis was administered mainly as a continuous infusion, an overnight infusion, or in one to three 1-h boluses in 62 (31%), 98 (48%) and 43 (21%) patients, respectively. Our findings suggest that, in some settings, patients may be receiving excessive volumes of hydration by less comfortable routes such as the intravenous route. Increased education and research in this area are badly needed.

    Cancer-related direct-to-consumer advertising (DTCA) is controversial because cancer treatment is complex and entails more risks and costs than typical treatments that are advertised for other conditions. Drawing from the Structural Influence Model of Communication, this study explores communication inequalities in DTCA exposure across social determinants among a population-based sample of 2013 patients diagnosed with breast, prostate, or colorectal cancers. Three survey items assessed patients' frequency of encountering ads concerning treatment alternatives for cancer, dealing with side effects of treatment, and doctors or hospitals offering services for cancer following their diagnosis. The analysis showed that overall exposure to DTCA in this study population was modest (median was once per week). Breast cancer patients reported significantly higher exposure to all three ad categories and overall DTCA exposure than prostate and colorectal cancer patients. Older patients consistently reported lower overall exposure to DTCA across the three cancer types. Other significant correlates included ethnicity (higher exposures among African American prostate cancer patients vs. White; lower exposures in Hispanic colorectal cancer patients vs. White) and cancer stage (higher exposures in Stage IV prostate cancer patients vs. Stages 0-II). Education level did not predict patients' DTCA exposure. The implications of these observed inequalities in DTCA exposure on cancer outcomes are discussed.

    The authors retrospectively analyzed high resolution (HR) CT scans of the brain in 23 patients with surgically proved primary lung cancer and intracranial metastatic lesions from April 1986 to March 1990. The purpose of this study was to evaluate the relationship between histopathologic types of primary lung cancer and HRCT findings of brain. The results were as follows: The locations of metastatic lesion were intraaxial in 93% and extraaxial in 7%. In the intraaxial lesions, most were in the supratentorial area (83%) and the remainer in the infratentorial area (10%). Among the supratentorial lesions, the parietal lobe was the most commonly involved (33%), while the second most common location was frontal lobe (22%). The HRCT showed multiple lesions in 52% and solitary lesions in 48%. All cell types except for squamous cell carcinoma showed the same incidence in multiplicity, and the squamous cell carcinoma showed slightly more multiple lesions rather than solitary ones. The degree of peritumoral edema was none in 4%, mild in 25%, moderate in 46%, and severe in 25%. All cell types except for squamous cell carcinoma in general showed a moderate degree of edema, and the squamous cell carcinoma mainly showed mild and severe edema. Precontrast CT scans showed mixed density in 52%, isodensity in 24%, low density in 19%, and high density in 5%. All cell types except for large cell carcinoma showed mixed density, the large cell carcinoma showed a low density unlike the others. Hemorrhages were seen in 24% and noted in all cell types except for large cell carcinoma. Postcontrast CT scans showed ring enhancement in 64%, nodular enhancement in 20%, and inhomogeneous enhancement in 16%. All cell types except for small cell carcinoma generally showed ring enhancement, and the small cell carcinoma showed a variable degree of enhancement

    Full Text Available Objective: To study the correlation of MRI apparent diffusion coefficient (ADC value of invasive breast cancer with tumor tissue growth and angiogenesis. Methods: Patients with breast mass who were treated in Wuhan No. 6 Hospital between March 2014 and May 2017 were selected as the research subjects and divided into group A with invasive ductal carcinoma, group B with intraductal carcinoma and group C with benign lesion according to the biopsy results, magnetic resonance diffusion-weighted imaging was conducted to determine ADC values, and biopsy tissue was taken to determine the expression of proliferation genes and angiogenesis genes. Results: USP39, CyclinD1, VEGF, bFGF, Angplt-2, Angplt-3 and Angplt-4 protein expression levels in lesions of group A and group B were significantly higher than those of group C while ADC value as well as ALEX1 and Bax protein expression levels were significantly lower than those of group C; USP39, CyclinD1, VEGF, bFGF, Angplt-2, Angplt-3 and Angplt-4 protein expression levels in lesions of group A were significantly higher than those of group B while ADC value as well as ALEX1 and Bax protein expression levels was significantly lower than those of group B; USP39, CyclinD1, VEGF, bFGF, Angplt-2, Angplt-3 and Angplt-4 protein expression levels in invasive breast cancer tissue with high ADC value were significantly lower than those in invasive breast cancer tissue with low ADC value while ALEX1 and Bax protein expression levels were significantly higher than those in invasive breast cancer tissue with low ADC value. Conclusion: The decrease of ADC value of invasive breast cancer is closely related to cancer cell proliferation and angiogenesis.

    Older cancer patients are a highly heterogeneous population in terms of global health and physiological reserves, and it is often difficult to determine the best treatment. Moreover, clinical tools currently used to assess global health require dedicated time and lack a standardized end score. Circulating markers of biological age and/or fitness could complement or partially substitute the existing screening tools. In this study we explored the relationship of potential ageing/frailty biomarkers with age and clinical frailty. On a population of 82 young and 162 older non-metastatic breast cancer patients, we measured mean leukocyte telomere length and plasma levels of interleukin-6 (IL-6), regulated upon activation, normal T cell expressed and secreted (RANTES), monocyte chemotactic protein 1 (MCP-1), insulin-like growth factor 1 (IGF-1). We also developed a new tool to summarize clinical frailty, designated Leuven Oncogeriatric Frailty Score (LOFS), by integrating GA results in a single, semi-continuous score. LOFS' median score was 8, on a scale from 0=frail to 10=fit. IL-6 levels were associated with chronological age in both groups and with clinical frailty in older breast cancer patients, whereas telomere length, IGF-1 and MCP-1 only correlated with age. Plasma IL-6 should be further explored as frailty biomarker in cancer patients.

    Background and purpose: Many head and neck cancer (HNC) survivors experience diminished quality of life due to radiation-induced dysphagia. The aim of this study was to investigate frequency, intensity and dose–volume dependency for late dysphagia in HNC patients treated with curative IMRT. Materials and methods: Candidates for the study were 294 patients treated with primary IMRT from 2006 to 2010; a total of 259 patients accepted to participate by answering the EORTC QLQ-C30 and H and N35 questionnaires. A total of 65 patients were further examined with modified barium swallow (MBS) and saliva collection. Data on patient, tumor and treatment characteristics were prospectively recorded in the DAHANCA database. Dose–volume histograms (DVH) of swallowing-related structures were retrospectively analyzed. Results: QoL data showed low degree of dysphagia (QoL subscales scores of 17 and below) compared to objective measures. The most frequent swallowing dysfunction was retention; penetration and aspiration was less common. In general, objective measurements and observer-assessed late dysphagia correlated with dose to pharyngeal constrictor muscles (PCM), whereas QoL endpoints correlated with DVH parameters in the glottis/supraglottic larynx. Both xerostomia and dysphagia has been reduced after introduction of IMRT. Conclusions: Radiation-induced dysphagia is still important, with a high degree of retention and penetration. Introduction of parotid-sparing IMRT has reduced the severity of dysphagia, primarily through a major reduction in xerostomia. Dose–response relationships were found for specific dysphagia endpoints

    Cancer can have a serious impact on patient well-being and quality of life. The international literature reports a higher prevalence of psychosocial problems among cancer patients; primarily problems associated with difficulties in the family, duties in the household, work and leisure, sexuality and finances. The prevalence of these problems among Danish cancer patients is still unknown. A questionnaire assessing psychosocial problems and needs was mailed out to all patients who had been at the Department of Oncology, Aarhus Hospital in week 35, 2004. A total of 71%, i.e. 515 patients (34% men and 66% women) in active treatment and control returned the questionnaire. High levels of emotional distress were reported by 39% of the patients. High levels of distress were primarily related to problems with worries about their spouses, household duties, financial problems and experiences of insufficient collaboration between health care and social services. Between 19% and 25% of the patients required further help to handle emotional problems, legal and financial problems and practical problems in the home. A considerable proportion of oncology patients experience significant levels of distress. This group of distressed patients also report unmet needs for psychosocial support.

    Full text: The coexistence of hyperthyroidism and thyroid cancer is a rare event. The aim of this study was to evaluate the relevance of the association of hyperthyroidism and thyroid cancer. Method: From 1st January 2006 to 31st December 2006, a total of 388 new hyperthyroid patients attended the Institute of Nuclear Medicine and Ultrasound for radioiodine therapy. Eighty-two of them were selected before radioiodine therapy, on the basis of findings on palpation and ultrasound (USG) examination, to undergo fine needle aspiration cytology (FNAC) for cytological diagnosis. USG examination was performed to localize and mark the position of nodule/nodules for FNAC and, in cases of nonpalpable nodules, USG guided FNAC was done. In the case of non-nodular patients, guided FNAC was done in sonographically suspicious areas. Results: FNAC report was positive for thyroid cancer in 4 patients. Histopathology examination revealed the presence of papillary carcinoma. Among the four positive cases, one had multi-nodular goitre, two had uni-nodular goiters and one had no nodule. Another patient had a negative FNAC report but due to a huge goiter, the patient underwent surgery and histopathology revealed the presence of papillary carcinoma. Conclusion: Although the occurrence of thyroid cancer in hyperthyroid patients is rare, the presence of a nodule should be carefully evaluated to exclude the presence of concurrent malignancy. FNAC (USG guided in case of non-palpable nodules) is found helpful before radioiodine therapy or surgery. (author)

  7. Nutritional support for malnourished patients with cancer.

    2011-03-01

    Cancer and its treatments frequently have a negative impact on the weight and nutritional status of patients. Weight loss is associated with reduced survival and poorer outcomes of treatment but is not well characterized and frequently confused with cachexia, which may complicate the interpretation of studies of nutritional support. The aims of this review were to examine the impact of cancer on nutritional status and to review the role of simple oral nutritional interventions and novel agents. The terms weight loss, malnutrition and cachexia refer to different entities and new definitions have recently been proposed that take account of the role of the underlying inflammatory processes. Oral nutritional interventions are widely recommended for malnourished cancer patients, but the evidence for their benefits to clinical, nutritional and patient-centred outcomes is limited. Meta-analysis has highlighted the variability in response to simple nutritional interventions of different cohorts of cancer patients and suggested that improvements in nutritional endpoints and aspects of quality of life may be achieved in some patients. Recent research has largely focused on treatments aiming to modulate the inflammatory processes associated with cachexia, but to date has not identified a single treatment with clear efficacy. Studies characterizing the potential for nutritional support in combination with anti-inflammatory agents in defined patient groups are defined to advance the evidence base in this area.

    Persons with colon cancer experience considerable psychological stress due to physical and social changes brought on by illness, increasing their risk of depressive disorder (DD). We examine the prevalence of DD and depressive symptoms and determine baseline demographic, social, psychological, and physical health correlates. A convenience sample of 70 cancer patients in Jeddah, Saudi Arabia, was screened for DD using an abbreviated version of the Structured Clinical Interview for Depression (SCID) and for depressive symptoms using the Hamilton Depression Rating Scale (HDRS). Demographic, psychosocial, psychiatric, and physical health characteristics were also assessed, along with past treatments for colon cancer. Bivariate and multivariate analyses identified predictors of DD and symptoms. The 1-month prevalence of DD was 30.0% (12.9% major depression, 5.7% minor depression, and 11.4% for dysthymia) and significant depressive symptoms were present in 57.1% (HDRS 8 or higher), including having persistent suicidal thoughts for 2 weeks or longer wthin the past month (14.3%) . Low social support and having a co-morbid psychiatric illness (particularly anxiety) independently predicted DD based on the SCID. Saudi nationality, poor financial situation, low social support, and co-morbid psychiatric illness independently predicted depressive symptoms on the HDRS. Surprisingly, stage of cancer, duration of cancer, and treatments for cancer were unrelated to DD or depressive symptoms. DD and significant depressive symptoms are common in patients with colon cancer in Saudi Arabia, and are predicted by a distinct set of demographic and psychosocial risk factors that may help with identification. Demographic and psychological risk factors were more likely to be associated with depression than cancer characteristics in this sample. Copyright © 2014 John Wiley & Sons, Ltd.

    Full Text Available Diagnostics of psycho-emotional disorders of patients with malignant diseases of the prostate is not doubt, because timely correction contributes to the shortening of rehabilitation period and restoration of the quality of life of patients after treatment. Detection and diagnosis of prostate cancer for many patients is stressful and causes changes in the affective sphere, and manifests itself in increased levels of anxiety and depression in men. To cope with stress is possible due to the used coping strategies.Purpose. Studying the coping mechanisms in prostate cancer patients.Materials and methods. 56 men treated in FGBU "LRTS" Russian Ministry of Health. The average age was 65.7 ± 6.1 years. The average duration of the disease prostate cancer is 3 ± 2 months. All men were subjected to the standard algorithm for the evaluation of hormonal status, the PSA, taking a history, inspection and physical examination, magnetic resonance imaging and scintigraphy of bones of a skeleton. All the patients underwent laparoscopic radical prostatectomy. Psychological testing with the use of the method of "Coping test" the scale of reactive and personal anxiety for the differentiated evaluation of anxiety. Results. The most common for prostate cancer revealed constructive coping strategies are "planning solve", "selfcontrol" and "search of social support". According to the scale Spielberg–Hanin a high level of situational anxiety was revealed.Conclusion. According to the results of the research, patients with prostate cancer are likely to use constructive coping strategies, that leads to stabilization of psycho-emotional state of men and promotes more effective adaptation in the terms of stress, that is caused by treatment of prostate cancer.

    Full Text Available Negative emotions (distress are recognized as part of the psychological profile of patients diagnosed with advanced stage cancer. However, most patients are not accustomed to verbalize feelings towards their physician, and generally towards family and medical care personnel. The purpose of this paper is to analyze the expression of emotions by patients in advanced stages of cancer, respectively the means by which they get to express emotions. To this respect, we identified the most common types of emotions expressed, or metaphors used by patients to describe their emotions and topics that trigger emotions. Words and phrases most commonly used are in relation to: fear, anxiety, depression, guilt, negligence, concern. They are uttered in order to depict the network created between disclosed emotions and topics on health status, symptoms, adverse effects and therapeutic choice, patient privacy, and social and family issues.

    The large body of empirical research suggesting that patients' spiritual and existential experiences influence the disease process has raised the need for health care professionals to understand the complexity of patients' spiritual pain and distress. The current study explores the multidimensional nature of spiritual pain, in patients with end-stage cancer, in relation to physical pain, symptom severity, and emotional distress. The study combines a quantitative evaluation of participants' intensity of spiritual pain, physical pain, depression, and intensity of illness, with a qualitative focus on the nature of patients' spiritual pain and the kinds of interventions patients believed would ameliorate their spiritual pain. Fifty-seven patients with advanced stage cancer in a palliative care hospital were interviewed by chaplains. Overall, 96% of the patients reported experiencing spiritual pain, but they expressed it in different ways: (1) as an intrapsychic conflict, (2) as interpersonal loss or conflict, or (3) in relation to the divine. Intensity of spiritual pain was correlated with depression (r = 0.43, p spiritual pain did not vary by age, gender, disease course or religious affiliation. Given both the universality of spiritual pain and the multifaceted nature of pain, we propose that when patients report the experience of pain, more consideration be given to the complexity of the phenomena and that spiritual pain be considered a contributing factor. The authors maintain that spiritual pain left unaddressed both impedes recovery and contributes to the overall suffering of the patient.

    Objective was to assess the significance of vascular endothelial growth factor (VEGF) protein over expression in human breast cancer, and its possible correlation with cell proliferation marker (Ki-67), grade and stage of breast cancer. We carried out this study at the Department of Pathology, Kufa University, between November 2006 and September 2007. A retrospective study was employed on paraffin-embedded blocks from 52 female patients with breast cancer. A group of 21 patients with benign breast lesions was included for comparison and 14 cases of normal breast tissue as control group. The investigation designed to employ immunohistochemistry using Avidin-Biotin Complex (ABC) method for detection of both VEGF and Ki-67. A total of 87 samples were included. Vascular endothelial growth factor immunoexpression was considered as positive in 61.5% of malignant and in 19% of benign breast lesions. No over expression sign has been noticed in normal breast tissue (p<0.005). No significant difference in VEGF over expression among different histological types of breast cancer (p<0.05). Vascular endothelial growth factor immunostaining was positively correlated with Ki-67, grade, stage, lymph node metastasis, and recurrence of breast cancer (p<0.05).No such correlation has been seen when the age of the patients has been considered. Vascular endothelial growth factor plays an important role in the pathogenesis of breast cancer evolution and supports the evidence of its role in angiogenesis and cell survival. This study recommended that the blocking of VEGF may be target for blocking angiogenesis and hence improving the efficacy of anti-cancer therapy. (author)

    Both sleep disorders and pain decrease quality of life in patients with Parkinson's disease (PD). However, little is known about the relationship between objective sleep disturbances and pain in patients with PD. This study aimed to (1) examine the clinical characteristics of pain in PD patients and (2) explore the correlation between pain and sleep disturbances in PD patients. Parkinson's disease patients (N = 144) underwent extensive clinical evaluations of motor and nonmotor symptoms and characteristics of pain. Overnight video-polysomnography was also conducted. Clinical characteristics and sleep parameters were compared between PD patients with or without pain. Pain was reported by 75 patients (52.1%), with 49 (65.3%) reporting pain of at least moderate severity. PD patients with pain were older and had longer disease duration, more severe PD symptoms as assessed by Hoehn and Yahr stage and the Unified Parkinson's Disease Rating Scale, and higher L-dopa equivalent daily dose compared with PD patients without pain. PD patients with pain also showed significantly decreased sleep efficiency (57.06% ± 15.84% vs. 73.80% ± 12.00%, P daily living, depressed mood, higher percentage of N1 sleep, and lower sleep efficiency were independent predictors of pain in patients with PD. Musculoskeletal pain is the most common type of pain in patients with PD. Disrupted sleep continuity, altered sleep architecture, depressed mood, and compromised activities of daily living may be associated with pain in patients with PD. © 2017 World Institute of Pain.

    Full Text Available The underlying reasons for the increasing occurrence of male reproductive diseases (MRD such as hypospadias, cryptorchidism, and testicular cancer (TC over the last decades are still unknown. It has been hypothesized that the risk of MRD is determined in utero and that pregnancy dietary intake could also affect MRD risk in the offspring. Various studies in animals reported that cocoa and theobromine, the main stimulant of cocoa, exert toxic effects on the testis, inducing testicular atrophy and impaired sperm quality. A correlation analysis was conducted to examine the possible role of cocoa consumption on the occurrence of selected MRD during the prenatal and early life period of cases. The incidence rates between 1998-2002 of TC in 18 countries obtained from Cancer Incidence in Five Continents were correlated with the average per-capita consumption of cocoa (kg/capita/year (FAOSTAT-Database in these countries from 1965 to 1980, i.e. the period corresponding to the early life of TC cases. In order to test the above correlation in the case of hypospadias, the mean prevalence at birth in 20 countries (1999-2003 with average per-capita consumption of cocoa in these countries in the same period corresponding to pregnancy were used. The consumption of cocoa in the period 1965–80, was most closely correlated with the incidence of TC in young adults (r=0.859; p<0.001. An analogous significant correlation was also observed between early cocoa consumption and the prevalence rates of hypospadias in the period 1999-2003 (r=0.760; p<0.001. Although the ecological approach used in this study cannot provide an answer on the causal relationship between consumption of cocoa in early life and TC and hypospadias, the results are suggestive and indicate the need of further analytic studies to investigate the role of individual exposure to cocoa, particularly during the prenatal and in early life of the patients.

    We have validated differences in DNA methylation levels of candidate genes previously reported to discriminate between normal colon mucosa of colon cancer patients and normal colon mucosa of individuals without cancer. Here, we report that CpG sites in 16 of the 30 candidate genes selected show significant differences in mean methylation level in normal colon mucosa of 24 cancer patients and 24 controls. A support vector machine trained on these data and data for an additional 66 CpGs yielded an 18-gene signature, composed of 10 of the validated candidate genes plus eight additional candidates. This model exhibited 96% sensitivity and 100% specificity in a 40-sample training set and classified all eight samples in the test set correctly. Moreover, we found a moderate-strong correlation (Pearson coefficients r=0.253-0.722) between methylation levels in colon mucosa and methylation levels in peripheral blood for seven of the 18 genes in the support vector model. These seven genes, alone, classified 44 of the 48 patients in the validation set correctly and five CpGs selected from only two of the seven genes classified 41 of the 48 patients in the discovery set correctly. These results suggest that methylation biomarkers may be developed that will, at minimum, serve as useful objective and quantitative diagnostic complements to colonoscopy as a cancer-screening tool. These data also suggest that it may be possible to monitor biomarker methylation levels in tissues collected much less invasively than by colonoscopy. PMID:24806665

    Purpose: To determine quality of life (QOL) and health utility in irradiated laryngeal cancer survivors. Materials and Methods: Over 6 months, consecutive follow-up patients at a comprehensive cancer centre completed the QOL questionnaire FACT-H and N and the time trade-off (TTO) utility instrument. Results: Inclusion criteria were met by 339 patients, of whom 269 were eligible, 245 were approached, and 120 agreed to participate. Most participants were men (83%) who had received radiotherapy (97%) for Stage I disease (53%) of the glottis (75%); 7% had undergone total laryngectomy. Participants differed from nonparticipants only in being younger (mean age, 65 vs. 68 years, p = 0.0049) and having higher performance status (Karnofsky 88 vs. 84, p = 0.0012). The average scores for FACT-H and N and the TTO were 124/144 (SD, 14) and 0.90/1.0 (SD, 0.16) respectively. FACT-H and N score was more highly correlated with Karnofsky score (r = 0.43, p = 0.001) than with the TTO (r = 0.29, p = 0.002). Gender predicted QOL (means: M = 125, F 118), while natural speech, no relapses, and more time since initial treatment predicted higher utility. Conclusion: The QOL of irradiated laryngeal cancer survivors was reasonably high and independent of initial disease variables. The QOL questionnaire correlated more strongly with performance status than with utility, suggesting that QOL and utility measures may be perceived differently by patients
