    In the nineteenth century the main goal of medicine was predictive: diagnose the disease and achieve a satisfying prognosis of the patient's chances. Today the effort has shifted to cure the disease. Since the twentieth century, the word prognosis has also been used in nonmedical contexts, for example in corporate finance or elections. The most accurate form of prognosis is achieved statistically. Based on different prognostic factors it should be possible to tell patients how they are expected to do after prostate cancer has been diagnosed and how different treatments may change this outcome. A prognosis is a prediction. The word prognosis comes from the Greek word (see text) and means foreknowing. In the nineteenth century this was the main goal of medicine: diagnose the disease and achieve a satisfying prognosis of the patient's chances. Today the effort has shifted towards seeking a cure. Prognostic factors in (prostate) cancer are defined as "variables that can account for some of the heterogeneity associated with the expected course and outcome of a disease". Bailey defined prognosis as "a reasoned forecast concerning the course, pattern, progression, duration, and end of the disease. Prognostic factors are not only essential to understand the natural history and the course of the disease, but also to predict possible different outcomes of different treatments or perhaps no treatment at all. This is extremely important in a disease like prostate cancer where there is clear evidence that a substantial number of cases discovered by prostate-specific antigen (PSA) testing are unlikely ever to become clinically significant, not to mention mortal. Furthermore, prognostic factors are of paramount importance for correct interpretation of clinical trials and for the construction of future trials. Finally, according to WHO national screening committee criteria for implementing a national screening programme, widely accepted prognostic factors must be defined before

    In ovarian cancer, translational research on the prognostic impact of molecular biological factors has until now not led to clinical implementation of any of these factors. This is partly due to the often conflicting results of different prognostic factor studies on the same molecular biological fac

    Objective: To evaluate the relationship between clinicopathologic features and prognosis of col-orectal cancer after surgical treatment. Methods: The relationship between clinicopathological character-istics and prognosis of 941 patients with colorectal cancer after surgical treatment were investigated by univariate and multivariate analysis. Results: The overall 3- and 5-year survival rates of patients withcolorectal cancer after surgical treatment were 63.2% and 60.8% respectively with a median survival of 1841 days. Univariate analysis revealed that such factors as gross findings, degree of differentiation, depth of infiltration, nodal and distant metastasis and neoplastic intestinal obstruction were correlated with the survival rate. Dukes stages, gross tumor configuration, intramural spread and differentiation degree were shown to be available independent prognostic factors by multivariate analysis. Conclusion: Dukes stage,as the most important available independent prognostic factor for colorectal cancer (P<0.0005), can be used to assess the postoperative survival.

    The psychological impact of an unfavorable genetic test result for counselees at risk for hereditary cancer seems to be limited: only 10-20 % of counselees have psychological problems after testing positive for a known familial mutation. The objective of this study was to find prognostic factors that can predict which counselees are most likely to develop psychological problems after presymptomatic genetic testing. Counselees with a 50 % risk of BRCA1/2 or Lynch syndrome completed questionnaires at three time-points: after receiving a written invitation for a genetic counseling intake (T1), 2-3 days after receiving their DNA test result (T2), and 4-6 weeks later (T3). The psychological impact of the genetic test result was examined shortly and 4-6 weeks after learning their test result. Subsequently, the influence of various potentially prognostic factors on psychological impact were examined in the whole group. Data from 165 counselees were analyzed. Counselees with an unfavorable outcome did not have more emotional distress, but showed significantly more cancer worries 4-6 weeks after learning their test result. Prognostic factors for cancer worries after genetic testing were pre-existing cancer worries, being single, a high risk perception of getting cancer, and an unfavorable test result. Emotional distress was best predicted by pre-existing cancer worries and pre-existing emotional distress. The psychological impact of an unfavorable genetic test result appears considerable if it is measured as "worries about cancer." Genetic counselors should provide additional guidance to counselees with many cancer worries, emotional distress, a high risk perception or a weak social network. PMID:26475052

    AIM: To analyse the prognostic factors in 165 colorectal patients aged ≥70.METHODS: One hundred and sixty-five elderly patients with colorectal cancer diagnosed by histology were entered into the retrospective study between 1994 and 2001. Patients were given optimal operation alone, chemotherapy after operation, or chemotherapy alone according to tumor stage,histology, physical strength, and co-morbid problems.Survival rate was calculated by Kaplan-Meier method, and compared with meaningful variances by Log-rank method.Prognostic factors were analyzed by Cox regression.RESULTS: The 1,2,3,4,5 year survival rate (all-cause rnortality)was 87.76%, 65.96%, 52.05%, 42.77%, 40.51%,respectively. The mean survival time was 41.89±2.33 months (95% CI: 37.33-46.45 months), and the median survival time was 37 months. Univariate analysis showed that factors such as age, nodal metastasis, treatment method, Duke's stage, gross findings, kind of histology, and degree of differentiation had influences on the survival rate. Multivariate analysis showed that factors such as treatment method,Duke's stage, kind of histology and degree of differentiation were independent prognostic factors.CONCLUSION: This study suggests that the prognosis of elderly colorectal cancer patients is influenced by several factors. Most of elderly patients can endure surgery and/or chemotherapy, and have a long-time survival and good quality of life.

    Introduction Telomere length, a marker of cell aging, seems to be affected by the same factors thought to be associated with breast cancer prognosis. Objective To examine associations of peripheral blood cell-measured telomere length with traditional and potential prognostic factors in breast cancer patients. Methods We conducted a cross-sectional analysis of data collected before surgery from 162 breast cancer patients recruited consecutively between 01/2011 and 05/2012, at a breast cancer reference center. Data on the main lifestyle factors (smoking, alcohol consumption, physical activity) were collected using standardized questionnaires. Anthropometric factors were measured. Tumor biological characteristics were extracted from pathology reports. Telomere length was measured using a highly reproducible quantitative PCR method in peripheral white blood cells. Spearman partial rank-order correlations and multivariate general linear models were used to evaluate relationships between telomere length and prognostic factors. Results Telomere length was positively associated with total physical activity (rs = 0.17, P = 0.033; Ptrend = 0.069), occupational physical activity (rs = 0.15, P = 0.054; Ptrend = 0.054) and transportation-related physical activity (rs = 0.19, P = 0.019; P = 0.005). Among post-menopausal women, telomere length remained positively associated with total physical activity (rs = 0.27, P = 0.016; Ptrend = 0.054) and occupational physical activity (rs = 0.26, P = 0.021; Ptrend = 0.056) and was only associated with transportation-related physical activity among pre-menopausal women (rs = 0.27, P = 0.015; P = 0.004). No association was observed between telomere length and recreational or household activities, other lifestyle factors or traditional prognostic factors. Conclusions Telomeres are longer in more active breast cancer patients. Since white blood cells are involved in anticancer immune responses, these findings suggest that even regular low

    Gallbladder cancer is the most common tumor of the biliary tract and it is associated with a poor prognosis. Unexpected gallbladder cancer is a cancer incidentally discovered, as a surprise, at the histological examination after cholecystectomy for gallstones or other indications. It is a potentially curable disease, with an intermediate or good prognosis in most cases. An adequate surgical strategy is mandatory to improve the prognosis and an adjunctive radical resection may be required depending on the depth of invasion. If the cancer discovered after cholecystectomy is a pTis or a pT1a, a second surgical procedure is not mandatory. In the other cases (pT1b, pT2 and pT3 cancer) a re-resection (4b + 5 liver segmentectomy, lymphadenectomy and port-sites excision in some cases) is required to obtain a radical excision of the tumor and an accurate disease staging. The operative specimens of re-resection should be examined by the pathologist to find any "residual" tumor. The "residual disease" is the most important prognostic factor, significantly reducing median disease-free survival and disease-specific survival. The other factors include depth of parietal invasion, metastatic nodal disease, surgical margin status, cholecystectomy for acute cholecystitis, histological differentiation, lymphatic, vascular and peri-neural invasion and overall TNM-stage.

    The aim of this study is to determine if breast conservative treatment is justified for patients with a positive family history of breast cancer and to investigate whether they have a worse prognosis. We performed a prospective cohort study of breast cancer patients, treated with breast conservative treatment with radiotherapy at the Radiotherapy Department of the Medisch Spectrum Twente. Between 1984 and 1996, 1204 patients with T1 and T2 or =2 FDRs. The local recurrence rate was 4.1%, with similar rates for all groups. In young patients, or =2 FDRs. Patients with a positive FH had significantly more contralateral tumours. The 5-year corrected survival was 91.3%. Among patients with a positive FH, a 5-year corrected survival of 91% was observed and the survival 100% among patients with one and > or =2 FDR. Family history is not a contraindication for breast conservative treatment and is not associated with a worse prognosis. Family history is not a prognostic factor for local recurrence rate in patients older than 40 years.

    Purpose : To analyse clinical outcome and prognostic factors according to treatment modality, this paper report our experience of retrospective study of patients with esophageal cancer. Materials and Methods : One hundred and ten patients with primary esophageal cancer who were treated in Presbyterian Medical Center from May 1985 to December 1992. We analysed these patients retrospectively with median follow up time of 28 months, one hundred and four patients(95%) were followed up from 15 to 69 months. In methods, twenty-eight patients were treated with median radiation dose irradiated 54.3Gy only. Fifty-six patients were treated with combined chemoradiotherapy. Sixteen cases of these patients were treated with concurrent chemoradiation and the other patients(forty cases) were treated sequential chemoradiotherapy. In concurrent chemoradiotherapy group, patients received 5-FU continuous IV infusion for 4 days. Cisplatin IV bolus, and concurrent esophageal irradiation to 30 Gy. After that patients received ?Fu continuous IV, Cisplatin bolus injection and Mitomycin-C bolus IV, Bleomycin continuous IV, and irradiation to 20 Gy. In sequential chemoradiotherapy group, the chemotherapy consisted of 5-FU 1,000 mg/m2 administered as a continuous 24 hour intravenous infusion during five days and Cisplatin 80-100 mg/m2 bolus injected, or Bleomycin, Vinblastine, Cisplatin, Methotrexate were used of 1 or 2 cycles. After preoperative concurrent chemoradiation, twenty-six patients underwent radical esophagectomy. Results ; ninety-three patients could be examined for response assessment. By treatment modality, response rates were 85.1% for radiation alone group and 86.3% for combined chemoradiation group. But in operation group, after one cycle of concurrent chemoradiation treatment, response rate was 61.9%. The pathologic complete response were 15.4% in operation group. Overall median survival was 11 months and actuarial 5-year survival rate was 8%. The median survival interval

    AIM: Colorectal cancers result from the accumulation of several distinct genetic alterations. This study was to investigate the frequency and prognostic value of loss of heterozygosity (LOH) and microsatellite instability (MSI) at 14 genetic loci located near or within regions containing important genes implicated in colorectal tumorigenesis.METHODS: We studied colorectal cancers with corresponding normal mucosae in 207 patients (139 males and 68 females,mean age at the time of tumor resection 66.2±12.4 years,range 22-88 years). There were 37 right-sided colonic tumors, 85 left-sided colonic tumors and 85 rectal tumors.The distribution of tumor staging was stage Ⅰ in 25, stage Ⅱ in 73, stage Ⅲ in 68, and stage Ⅳ in 41. We analyzed the LOH and MSI of HPC1, hMSH2, hMLH1, APC, MET,P53, NH23-H1, DCC, BAT25, BAT26, D17S250, MYCL1 and D8S254 with fluorescent polymerase chain reaction and denatured gel electrophoresis. High-frequency LOH was determined to be greater than three, or more than 50%of the informative marker with LOH. High-frequency MSI (MSI-H) was determined as more than four markers with instability (>30%). Correlations of LOH and MSI with clinical outcomes and pathological features were analyzed and compared.RESULTS: The occurrence of MSI-H was 7.25%, located predominantly in the right colons (7/15) and had a higher frequency of poor differentiation (6/15) and mucin production (7/15). LOH in at least one genetic locus occurred in 78.7% of the tumors and was significantly associated with disease progression. Of the 166 potentially cured patients, 45 developed tumor recurrence within 36 mo of follow-up. Clinicopathological factors affecting 3-year disease-free survival (DFS) were TNM staging, grade of differentiation, preoperative CEA level, and high LOH status. Patients with high LOH tumors had a significantly lower DFS (50%) compared with patients with low LOH tumors (84%). Of the patients developing subsequent tumor recurrence, the number and

    2016-03-01

    Colorectal cancer (CRC) is due to different types of genetic alterations that are translated into different phenotypes. Among them, CpG island methylator phenotype (CIMP+) is the most recently involved in carcinogenesis of some CRC. The malignant transformation in this case is mainly due to the transcriptional inactivation of tumor suppressor genes. CIMP+ are reported to be more frequently found in the elderly and in women. The tumors are more frequently located in the proximal part of the colon, BRAF mutated and are associated with microsatellite instability (MSI) phenotype. All sporadic MSI CRC belong to the methylator phenotype, however some non MSI CRC may also harbor a methylator phenotype. The prognostic value of CIMP is not well known. Most studies show a worse prognosis in CIMP+ CRC, and adjuvant treatments seem to be more efficient. We review here the current knowledge on prognostic and predictive values in CIMP+ CRC.

    Stefanie Aust

    Full Text Available Tumor cachexia is an important prognostic parameter in epithelial ovarian cancer (EOC. Tumor cachexia is characterized by metabolic and inflammatory disturbances. These conditions might be reflected by body composition measurements (BCMs ascertained by pre-operative computed tomography (CT. Thus, we aimed to identify the prognostically most relevant BCMs assessed by pre-operative CT in EOC patients.We evaluated muscle BCMs and well established markers of nutritional and inflammatory status, as well as clinical-pathological parameters in 140 consecutive patients with EOC. Furthermore, a multiplexed inflammatory marker panel of 25 cytokines was used to determine the relationship of BCMs with inflammatory markers and patient's outcome. All relevant parameters were evaluated in uni- and multivariate survival analysis.Muscle attenuation (MA-a well established BCM parameter-is an independent prognostic factor for survival in multivariate analysis (HR 2.25; p = 0.028. Low MA-reflecting a state of cachexia-is also associated with residual tumor after cytoreductive surgery (p = 0.046 and with an unfavorable performance status (p = 0.015. Moreover, MA is associated with Eotaxin and IL-10 out of the 25 cytokine multiplex marker panel in multivariate linear regression analysis (p = 0.021 and p = 0.047, respectively.MA-ascertained by routine pre-operative CT-is an independent prognostic parameter in EOC patients. Low MA is associated with the inflammatory, as well as the nutritional component of cachexia. Therefore, the clinical value of pre-operative CT could be enhanced by the assessment of MA.

    Almost one million new cases of gastric cancer were estimated to have occurred in 2012, making it the fifth most common malignancy in the world. It is also the third leading cause of cancer death of people of both genders worldwide. The aim of this study is to evaluate the significance of some prognostic factors for gastric cancer survival in 155 patients treated at Aleksandrovska University Hospital, Sofia, Bulgaria. This retrospective study includes patients diagnosed and treated at Department of Surgery of Aleksandrovska University Hospital for the 9-years period of time between January 2005 and December 2013. We classified the prognostic factors as patient-related (age at diagnosis specification, gender, and blood type), tumor-related (N-stage, tumor differentiation, process localization), and treatment related (patients who had radical surgery and adjuvant therapy). We found that blood type is the only statistically significant prognostic factor for overall survival from the patients-related group of factors (p = 0.030). The only prognostic factor from the ones in the tumor related group remains the N-stage according to the TNM classification (p = 0.003). Adjuvant could not prove its value for overall survival (p = 0.675).

Methods Total of 24,910 subjects diagnosed with lung cancer was analysed. Survival estimates by Kaplan-Meier methods. Cox proportional-hazards model estimated the death risk (hazard ratio (HR for various prognostic factors. Results The prognostic indicators associated with a higher risk of lung cancer deaths are male gender (males versus females; HR = 1.07, 95% confidence intervals (CI: 1.03–1.11, males diagnosed in later periods (shown in 1991–1994 versus 1987–1990; HR = 1.13, older age at diagnosis, large cell carcinoma (LCC/small cell carcinoma (SCC, and supportive care therapy over chemotherapy. The overall 5-year survival rate for lung cancer death was significantly poorer for males (21.3% than females (23.6%. Subjects with squamous cell carcinoma (SQCC and treatment by surgical resection alone had better prognosis. We find surgical resections to markedly increase 5-year survival rate from LCC, decreased risk of death from LCC, and no improved survival from SCC. Conclusion Gender and clinical characteristics (i.e. diagnostic period, diagnostic age, histological type and treatment modality play important roles in determining lung cancer survival.

    This study was performed to identify new significant prognostic factors in breast cancer patients irradiated for metastatic spinal cord compression (MSCC). The data of 504 patients with breast cancer patients with MSCC were retrospectively analyzed with respect to posttreatment motor function, local control of MSCC, and survival. The investigated potential prognostic factors included age, Eastern Cooperative Oncology Group (ECOG) performance score, number of involved vertebrae, other bone metastases, visceral metastases, pretreatment ambulatory status, interval from cancer diagnosis to radiotherapy of MSCC, time developing motor deficits before radiotherapy, and the radiation schedule. On multivariate analysis, better functional outcome was associated with ambulatory status prior to RT (estimate - 1.29, p < 0.001), no visceral metastases (estimate - 0.52, p = 0.020), and slower development of motor deficits (estimate + 2.47, p < 0.001). Improved local control was significantly associated with no other bone metastases (risk ratio (RR) 4.33, 95% confidence interval (CI) 1.36-14.02, p = 0.013) and no visceral metastases (RR 3.02, 95% CI 1.42-6.40, p = 0.005). Improved survival was significantly associated with involvement of only 1-2 vertebrae (RR 1.27, 95% CI 1.01-1.60, p = 0.044), ambulatory status before radiotherapy (RR 1.75, 95% CI 1.23-2.50, p = 0.002), no other bone metastases (RR 1.93, 95% CI 1.18-3.13, p = 0.009), no visceral metastases (RR 7.60, 95% CI 5.39-10.84, p < 0.001), and time developing motor deficits before radiotherapy (RR 1.55, 95% CI 1.30-1.86, p < 0.001). Several new independent prognostic factors were identified for treatment outcomes. These prognostic factors should be considered in future trials and may be used to develop prognostic scores for breast cancer patients with MSCC. (orig.)

    New prognostic markers in patients with colorectal cancer (CRC) are a prerequisite for individualized treatment. Prognostic importance of single nucleotide polymorphisms (SNPs) in the vascular endothelial growth factor A (VEGF-A) gene has been proposed. The objective of the present study was to investigate the prognostic importance of haplotypes in the VEGF-A gene in patients with CRC. The study included 486 patients surgically resected for stage II and III CRC, divided into two independent cohorts. Three SNPs in the VEGF-A gene were analyzed by polymerase chain reaction. Haplotypes were estimated using the PHASE program. The prognostic influence was evaluated using Kaplan-Meir plots and log rank tests. Cox regression method was used to analyze the independent prognostic importance of different markers. All three SNPs were significantly related to survival. A haplotype combination, responsible for this effect, was present in approximately 30% of the patients and demonstrated a significant relationship with poor survival, and it remained an independent prognostic marker after multivariate analysis, hazard ratio 2.46 (95% confidence interval 1.49–4.06), p < 0.001. Validation was provided by consistent findings in a second and independent cohort. Haplotype combinations call for further investigation.

    AIM: To investigate the prognostic factors of T4 gas-tric cancer patients without distant metastasis who could undergo potentially curative resection. METHODS: We retrospectively analyzed the clinical data of 71 consecutive patients diagnosed with T4 gas-tric cancer and who underwent curative gastrectomy at our institutions. The clinicopathological factors that could be associated with overall survival were evalu-ated. The cumulative survival was determined by the Kaplan-Meier method, and univariate comparisons be-tween the groups were performed using the log-rank test. Multivariate analysis was performed using the Cox proportional hazard model and a step-wise procedure.RESULTS: The study patients comprised 53 men (74.6%) and 18 women (25.4%) aged 39-89 years (mean, 68.9 years). Nineteen patients (26.8%) had postoperative morbidity: pancreatic fistula developed in 6 patients (8.5%) and was the most frequent compli-cation, followed by anastomosis stricture in 5 patients (7.0%). During the follow-up period, 28 patients (39.4%) died because of gastric cancer recurrence, and 3 (4.2%) died because of another disease or accident. For all patients, the estimated overall survival was 34.1% at 5 years. Univariate analyses identified the following statis-tically significant prognostic factors in T4 gastric cancer patients who underwent potentially curative resection: peritoneal washing cytology (P < 0.01), number of met-astatic lymph nodes (P < 0.05), and venous invasion (P < 0.05). In multivariate analyses, only peritoneal wash-ing cytology was identified as an independent prognos-tic factor (HR = 3.62, 95% CI = 1.37-9.57) for long-term survival. CONCLUSION: Positive peritoneal washing cytology was the only independent poor prognostic factor for T4 gastric cancer patients who could be treated with potentially curative resection.

    AIM: Liver metastases from breast cancer (BCLM) are associated with poor prognosis. Cytotoxic chemotherapy can result in regression of tumor lesions and a decrease in symptoms. Available data, in the literature, also suggest a subgroup of patients rraay berefit from surgery, but few talked about transcatheter arterial chemoembolization (TACE).We report the results of TACE and systemic chemotherapy for patients with liver metastases from breast cancer and evaluate the prognostic factors. METHODS: Forty-eight patients with liver metastases, from proved breast primary cancer were treated with TACEor systemic chemotherapy between January 1995 and December 2000. Treatment results were assessed according to WHO criteria, along with analysis of prognostic factors for survival using Cox regression model.RESULTS: The median follow-up was 28 mo (1-72 mo). Response rates were calculated for the TACE group and chemotherapy group, being 35.7% and 7.1%,respectively. The difference was significant. The one-, two- and three-year Survival rates for the TACE group were 63.04%, 30.35%, and 13.01%, and those for the systemic chemotherapy group were 33.88%, 11.29%, and 0%. According to univariate analysis, variables significantly associated with survival were the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight. Other factors such as age, the intervals between the primary to the metastases, the maximal diameter of the liver metastases, the number of liver metastases, extrahepatic metastasis showed no prognostic significances. These factors mentioned above such as the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight were also independent factors in multivariate analysis.CONCLUSION: TACE treatment of liver metastases from breast cancer may prolong survival in certain patients. This approach offers new promise for the curative treatment of the patients

    The data on 914 patients enrolled in four randomised trials in advanced ovarian cancer, consecutively conducted by the same cooperative group between 1978 and 1986, were analysed with the aims of: (1) determining the impact of selected prognostic variables on survival; (2) finding, from the interaction of favourable prognostic factors and treatment, an approximate estimate of the magnitude of the survival advantage associated with the use of platinum-based combination chemotherapy. The overall 3-year survival in this series of patients is twice that reported historically (22%; 95% CL 18.7-25.4). The proportional hazard regression model was used to perform the analysis on survival. Residual tumour size, age, FIGO stage and cell type were all independent determinants of survival. Differences in survival from the various prognostic groups were impressive with 5-year survival rates ranging from 7 to 62%. However, these differences were not qualitative (i.e. the kinetics of survival were similar for the best and the worst groups) suggesting that current prognostic factors are of little use for selecting 'biologically' different sub-populations. Platinum-based regimens were associated to an overall prolonged median survival, but this benefit was not observable in the subgroup with most favourable prognosis (less than 2 cm residual tumour size). The implications of these observations for clinical research and ovarian cancer patients care are discussed.

  14. Clinicopathologic characteristics and prognostic factors of 63 gastric cancer patients with metachronous ovarian metastasis

    International Nuclear Information System (INIS)

    This study aims to explore the clinicopathologic characteristics and prognostic factors of gastric cancer patients with metachronous ovarian metastasis. Clinicopathologic data were collected from 63 post-operative gastric cancer patients with metachronous ovarian metastasis. The patients were admitted to the Cancer Institute and Hospital, Chinese Academy of Medical Science and Peking Union Medical College between January 1999 and December 2011. A log-rank test was conducted for survival analysis. Possible prognostic factors that affect survival were examined by univariate analysis. A Cox regression model was used for multivariate analysis. The incidence of ovarian metastasis was 3.4% with a mean age of 45 years. Up to 65.1% of the patients were pre-menopausal. The mean interval between ovarian metastasis and primary cancer was 16 months. Lowly differentiated carcinoma ranked first in the primary gastric cancers. The majority of lesions occurred in the serous membrane (87.3%). The metastatic sites included N2-3 lymph nodes (68.3%), bilateral ovaries (85.7%), and peritoneal membrane (73%). Total resection of metastatic sites was performed (31.7%). The overall median survival was 13.6 months, whereas the overall 1-, 2-, and 3-year survival rates were 52.5%, 22.0%, and 9.8%, respectively. The 5-year survival rate was zero. Univariate analysis showed that the patient prognosis was correlated with metastatic peritoneal seeding, vascular tumor embolus, range of lesion excision, and mode of comprehensive treatment with adjuvant chemotherapy (P<0.05). Multivariate analysis indicated that metastatic peritoneal seeding was an independent prognostic factor for gastric cancer patients with ovarian metastasis (P<0.01). Effective control of peritoneal seeding—induced metastasis is important for improving the prognosis of gastric cancer patients with ovarian metastasis

    Full Text Available Abstract Background Pancreatic adenocarcinoma (PCA is one of the most lethal human malignancies, and radical surgery remains the cornerstone of treatment. After resection, the overall 5-year survival rate is only 10% to 29%. At the time of presentation, however, about 40% of patients generally have distant metastases and another 40% are usually diagnosed with locally advanced cancers. The remaining 20% of patients are indicated for surgery on the basis of the results of preoperative imaging studies; however, about half of these patients are found to be unsuitable for resection during surgical exploration. In the current study, we aimed to determine the clinicopathological characteristics that predict the resectability of PCA and to conduct a prognostic analysis of PCA after resection to identify favorable survival factors. Methods We retrospectively reviewed the medical files of 688 patients (422 men and 266 women who had undergone surgery for histopathologically proven PCA in the Department of Surgery at Chang Gung Memorial Hospital in Taiwan from 1981 to 2006. We compared the clinical characteristics of patients who underwent resection and patients who did not undergo resection in order to identify the predictive factors for successful resectability of PCA, and we conducted prognostic analysis for PCA after resection. Results A carbohydrate antigen 19–9 (CA 19–9 level of 37 U/ml or greater and a tumor size of 3 cm or more independently predicted resectability of PCA. In terms of survival after resection, PCA patients with better nutritional status (measured as having an albumin level greater than 3.5 g/dl, radical resection, early tumor stage and better-differentiated tumors were associated with favorable survival. Conclusions Besides traditional imaging studies, preoperative CA 19–9 levels and tumor size can also be used to determine the resectability of PCA. Better nutritional status, curative resection, early tumor stage and well

  16. Epidermal growth factor receptor as a prognostic factor in locally advanced rectal-cancer patients treated with preoperative chemoradiation

    International Nuclear Information System (INIS)

    Purpose: We investigated the prognostic value of epidermal growth factor receptor (EGFR) expression in pretreatment biopsy specimens from patients with locally advanced rectal cancer treated with preoperative chemoradiation. Methods and Materials: Pretreatment biopsy specimens from 92 patients with locally advanced rectal cancer were examined for EGFR expression by immunohistochemistry. EGFR expression was assessed by immunoreactive score (IRS). The prognostic value of EGFR expression was evaluated according to the level of EGFR expression. Results: Epidermal growth factor receptor expression was positive in 65 patients (71%). EGFR expression levels were low (IRS 0 to 5) in 83 patients (90%) and high (IRS 6 to 7) in 9 patients (10%). A high level of EGFR expression was statistically significant for shorter overall survival (p = 0.013), disease-free survival (p = 0.002), and distant metastasis-free survival (p = 0.003), as compared with a low level of expression in univariate analysis. Grouping based on positive or negative EGFR expression did not represent prognostic significance for survival. In multivariate analysis, high EGFR expression was an independent prognostic factor for decreased disease-free survival (relative risk 2.4, p = 0.041) and distant metastasis-free survival (relative risk 2.6, p = 0.04). Conclusions: Our results suggest that high level of EGFR expression in a pretreatment biopsy specimen may be a significant adverse prognostic factor for disease-free survival and distant metastasis-free survival

  18. A profile of prognostic and molecular factors in European and Māori breast cancer patients

    International Nuclear Information System (INIS)

    New Zealand Māori have a poorer outcome from breast cancer than non-Māori, yet prognostic data are sparse. The objective of this study was to quantify levels of prognostic factors in a cohort of self-declared Māori and European breast cancer patients from Christchurch, New Zealand. Clinicopathological and survival data from 337 consecutive breast cancer patients (27 Māori, 310 European) were evaluated. Fewer tumours were high grade in Māori women than European women (p = 0.027). No significant ethnic differences were detected for node status, tumour type, tumour size, human epidermal growth factor receptor, oestrogen and progesterone receptor (ER/PR) status, or survival. In addition, tumour and serum samples from a sub-cohort of 14 Māori matched to 14 NZ European patients were analyzed by immunohistochemistry and enzyme linked immunosorbent assay for molecular prognostic factors. Significant correlations were detected between increased grade and increased levels of hypoxia inducible factor-1 (HIF-1α), glucose transporter-1 (GLUT-1), microvessel density (MVD) and cytokeratins CK5/6 (p < 0.05). High nodal status correlated with reduced carbonic anhydrase IX (CA-IX). Negative ER/PR status correlated with increased GLUT-1, CA-IX and MVD. Within the molecular factors, increased HIF-1α correlated with raised GLUT-1, MVD and CK5/6, and CK5/6 with GLUT-1 and MVD (p < 0.05). The small number of patients in this sub-cohort limited discrimination of ethnic differences. In this Christchurch cohort of breast cancer patients, Māori women were no more likely than European women to have pathological or molecular factors predictive of poor prognosis. These data contrast with data from the North Island NZ, and suggest potential regional differences

    AIM: To investigate the efficiency of Cox proportional hazard model in detecting prognostic factors for gastric cancer.METHODS: We used the log-normal regression model to evaluate prognostic factors in gastric cancer and compared it with the Cox model. Three thousand and eighteen gastric cancer patients who received a gastrectomy between 1980 and 2004 were retrospectively evaluated. Clinic-pathological factors were included in a log-normal model as well as Cox model. The akaike information criterion (AIC) was employed to compare the efficiency of both models. Univariate analysis indicated that age at diagnosis, past history, cancer location, distant metastasis status, surgical curative degree, combined other organ resection, Borrmann type, Lauren's classification, pT stage, total dissected nodes and pN stage were prognostic factors in both log-normal and Cox models.RESULTS: In the final multivariate model, age at diagnosis,past history, surgical curative degree, Borrmann type, Lauren's classification, pT stage, and pN stage were significant prognostic factors in both log-normal and Cox models. However, cancer location, distant metastasis status, and histology types were found to be significant prognostic factors in log-normal results alone.According to AIC, the log-normal model performed better than the Cox proportional hazard model (AIC value:2534.72 vs 1693.56).CONCLUSION: It is suggested that the log-normal regression model can be a useful statistical model to evaluate prognostic factors instead of the Cox proportional hazard model.

    Although elevated resting heart rate (RHR) has been shown to be associated with mortality in the general population and patients with certain diseases, no study has examined this association in patients with breast cancer. A total of 4786 patients with stage I-III breast cancer were retrospectively selected from the Severance hospital breast cancer registry in Seoul, Korea. RHR was measured at baseline and the mean follow-up time for all patients was 5.0 ± 2.5 years. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated using Cox regression models. After adjustment for prognostic factors, patients in the highest quintile of RHR (≥85 beat per minute (bpm)) had a significantly higher risk of all-cause mortality (HR: 1.57; 95 %CI 1.05-2.35), breast cancer-specific mortality (HR: 1.69; 95 %CI 1.07-2.68), and cancer recurrence (HR: 1.49; 95 %CI 0.99-2.25), compared to those in the lowest quintile (≤67 bpm). Moreover, every 10 bpm increase in RHR was associated with 15, 22, and 6 % increased risk of all-cause mortality, breast cancer-specific mortality, and cancer recurrence, respectively. However, the association between RHR and cancer recurrence was not statistically significant (p = 0.26). Elevated RHR was associated with an increased risk of mortality in patients with breast cancer. The findings from this study suggest that RHR may be used as a prognostic factor for patients with breast cancer in clinical settings. PMID:27544225

  1. Prognostic factors for survival of women with unstable spinal bone metastases from breast cancer

    International Nuclear Information System (INIS)

    Bone metastases are an important clinical issue in women with breast cancer. Particularly, unstable spinal bone metastases (SBM) are a major cause of severe morbidity and reduced quality of life (QoL) due to frequent immobilization. Radiotherapy (RT) is the major treatment modality and is capable of promoting re-ossification and improving stability. Since local therapy response is excellent, survival of these patients with unstable SBM is of high clinical importance. We therefore conducted this analysis to assess survival and to determine prognostic factors for bone survival (BS) in women with breast cancer and unstable SBM. A total population of 92 women with unstable SBM from breast cancer who were treated with RT at our department between January 2000 and January 2012 was retrospectively investigated. We calculated overall survival (OS) and BS (time between first diagnosis of bone metastases until death) with the Kaplan-Meier method and assessed prognostic factors for BS with a Cox regression model. Mean age at first diagnosis of breast cancer was 60.8 years ± SD 12.4 years. OS after 1, 2 and 5 years was 84.8, 66.3 and 50 %, respectively. BS after 1, 2 and 5 years was 62.0, 33.7 and 12 %, respectively. An age > 50 years (p < .001; HR 1.036 [CI 1.015–1.057]), the presence of a single bone metastasis (p = .002; HR 0.469 [CI 0.292–0.753]) and triple negative phenotype (p < .001; HR 1.068 [CI 0.933–1.125]) were identified as independent prognostic factors for BS. Our analysis demonstrated a short survival of women with breast cancer and unstable SBM. Age, presence of a solitary SBM and triple-negative phenotype correlated with survival. Our results may have an impact on therapeutic decisions in the future and offer a rationale for future prospective investigations

  2. A retrospective analysis of survival and prognostic factors of male breast cancer from a single center

    International Nuclear Information System (INIS)

    Less than 1% of all breast cancer cases are found in men, who reportedly have inferior outcomes compared with matched women patients. Ethnic differences may also affect their prognosis. Here, we investigated overall survival (OS) and major prognostic factors for male breast cancer (MBC) in a cohort of Egyptian patients. We retrospectively analyzed OS in a cohort of 69 male patients with MBC who were surgically treated at the Mansoura Cancer Center, Egypt between 2000 and 2007. We registered demographic data, age, height, weight and body mass index, tumor size, histology, number of infiltrated axillary lymph nodes, hormone receptor (HR) status and metastatic presence, and TNM staging. Patients’ OS was the primary endpoint. Patients received treatment to the medical standards at the time of their diagnosis. In the 69 patients who met the inclusion criteria and had complete stored patient data, tumors ranged from T1c to T3. We could gather cancer-related survival data from only 56 patients. The collective 5-year survival in this cohort was 46.4%. Only five patients had distant metastasis at diagnosis, but they showed a null percent 5-year survival, whereas those with no lymph node infiltration showed a 100% 5-year survival. Lymph node status and tumor grading were the only prognostic factors that significantly affected OS. Lymph node status and tumor grade are the most important prognostic factors for overall survival of MBC in Egyptian male patients; whereas even remarkably low HR expression in MBC did not significantly affect OS. Further research is needed to understand the factors that affect this disease

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

  4. Evaluation of prognostic and predictive factors in breast cancer in Cuba. Its role in personalized therapy

    International Nuclear Information System (INIS)

    The identification of prognostic and predictive factors in breast cancer has allowed applying personalized therapeutic programs without achieving, still, the individualization for all patients. The objective of the present study was to evaluate the frequency of estrogen receptors, progesterone and HER2 along with the expression of the EGFR1 and ganglioside NglicolilGM3. 1509 patients found the frequency of expression of the aforementioned receivers, which were correlated with the morphological and General variables. It was compared the AcM recognition ior egf/r3 with a game of diagnosis - shopping, and the AcM 14F7 vitro tissue fresh and included in paraffin and in vivo labelled with 99mTc. It was obtained the frequency in Cuba of these prognostic and prediction markers of response, noting her hormone dependence of tumor associated with less aggressive features. The AcM 14F7 showed a broad recognition that was not correlated with prognostic factors, but was able to detect live in primary breast tumors. The ior egf/r3 exhibited 100% specificity and positive predictive value, as well as a sensitivity and negative predictive value of 68 and 73% respectively. The recognition of the AcM 14F7 and ior egf/r3 opens a new possibility of therapeutic directed against these targets for breast cancer (author)

  5. Lymph node ratio as a prognostic factor in head and neck cancer patients

    International Nuclear Information System (INIS)

    Lymph node status is one prognostic factor in head and neck cancer. The purpose of this study is to investigate the prognostic value of lymph node ratio (LNR) in head and neck cancer patients who received surgery plus postoperative chemoradiotherapy. From May 1991 to December 2012, a total of 117 head and neck cancer patients who received surgery plus postoperative chemoradiotherapy were analyzed. The primary sites were oral cavity (93), oropharynx (13), hypopharynx (6), and larynx (5). All patients had pathologically confirmed squamous cell carcinoma and 63 patients had neck lymph nodes metastasis. LNR was calculated for each patient. The endpoints were overall survival (OS), local failure-free survival (LFFS), and distant metastasis-free survival (DMFS). The median follow up time was 36 months, with a range from 3.4 to 222 months. The 3-year rates of OS, LFFS, and DMFS were 59.7, 70.3, and 81.8 %, respectively. The median value of LNR for lymph nodes positive patients was 0.1. In univariate analysis, patients with an LNR value less than 0.1 had better 3-year OS (67.0 % vs.41.0 %, p = 0.004), 3-year LFFS (76.1 % vs. 54.9 %, p = 0.015) and 3-year DMFS (87.2 % vs. 66.4 %, p = 0.06). Multivariate analysis revealed that LNR was an independent prognostic factor for OS (hazard ratio [HR] = 2.92; 95 % confidence interval [CI] = 1.367–6.242; p = 0.006) and LFFS (HR = 4.12; 95 % CI = 1.604–10.59; p = 0.003). LNR is an important prognosis factor for OS and LFFS in head and neck cancer patients.

    Full Text Available Pax transactivation domain interacting protein (PTIP associated protein 1, PA1, was a newly found protein participating in the modulation of transactivity of nuclear receptor super family members such as estrogen receptor (ER, androgen receptor (AR and glucocorticoid receptor (GR. Breast cancer is one of the most life threatening diseases for women and has tight association with estrogen and ER. This study was performed to understand the function of PA1 in breast cancer. The expression of PA1 had been evaluated in a total of 344 primary invasive breast cancer samples and examined the relationship with clinical output, relapse free survival (RFS, breast cancer-specific survival (BCSS. PA1 expression was observed in both nucleus and cytoplasm, however, appeared mainly in nuclear. PA1 nuclear expression was correlated with postmenopausal (P = 0.0097, smaller tumor size (P = 0.0025, negative Ki67 (P = 0.02, positive AR (P = 0.049 and positive ERβ (P = 0.0020. Kaplan-Meier analysis demonstrated PA1 nuclear positive cases seemed to have a longer survival than negative ones for RFS (P = 0.023 but not for BCSS (P = 0.23. In the Cox hazards model, PA1 nuclear protein expression proved to be a significant prognostic univariate parameter for RFS (P = 0.03, but not for BCSS (P = 0.20. In addition, for those patients without lymphnode metastasis PA1 was found to be an independent prognostic factor for RFS (P = 0.025, which was verified by univariate and multivariate analyses. These investigations suggested PA1 expression could be a potential prognostic indicator for RFS in breast cancer.

    Objective The objective of this retrospective study was to investigate the prognostic factors associated with survival among patients with extensive stage-smal cel lung cancer (ES-SCLC). Methods Clinical data from 66 patients with ES-SCLC diagnosed via histopathology or cytology between July 2005 and July 2009 at Anyang Tumor Hospital (China) were analyzed. Univariate and multivariate Kaplan-Meier, log-rank, and Cox proportional hazard regression analyses were conducted. Results The 12-, 24-, and 36-month survival rates among patients with ES-SCLC were 40.9%, 13.6%, and 6.1%, respectively. The median survival time (MST) was 10 months. Univariate analyses indicated that weight loss, eficacy of first-line chemotherapy, total number of chemotherapy cycles, treatment meth-od, and serum sodium levels significantly influenced survival among patients with ES-SCLC. Multivariate analyses suggested that the eficacy of first-line chemotherapy, total number of chemotherapy cycles, and serum sodium levels were independent prognostic factors associated with survival. Conclusion The eficacy of first-line chemotherapy, total number of chemotherapy cycles, and serum sodium levels are important prognostic factors for patients with ES-SCLC.

    Full Text Available Abstract Background To asses the clinical profile, treatment outcome and prognostic factors in primary breast lymphoma (PBL. Methods Between 1970 and 2000, 84 consecutive patients with PBL were treated in 20 institutions of the Rare Cancer Network. Forty-six patients had Ann Arbor stage IE, 33 stage IIE, 1 stage IIIE, 2 stage IVE and 2 an unknown stage. Twenty-one underwent a mastectomy, 39 conservative surgery and 23 biopsy; 51 received radiotherapy (RT with (n = 37 or without (n = 14 chemotherapy. Median RT dose was 40 Gy (range 12–55 Gy. Results Ten (12% patients progressed locally and 43 (55% had a systemic relapse. Central nervous system (CNS was the site of relapse in 12 (14% cases. The 5-yr overall survival, lymphoma-specific survival, disease-free survival and local control rates were 53%, 59%, 41% and 87% respectively. In the univariate analyses, favorable prognostic factors were early stage, conservative surgery, RT administration and combined modality treatment. Multivariate analysis showed that early stage and the use of RT were favorable prognostic factors. Conclusion The outcome of PBL is fair. Local control is excellent with RT or combined modality treatment but systemic relapses, including that in the CNS, occurs frequently.

    International Nuclear Information System (INIS)

    Purpose To assess the clinical profile, treatment outcome, and prognostic factors in primary spinal epidural lymphoma (PSEL). Methods and Materials Between 1982 and 2002, 52 consecutive patients with PSEL were treated in nine institutions of the Rare Cancer Network. Forty-eight patients had an Ann Arbor stage IE and four had a stage IIE. Forty-eight patients underwent decompressive laminectomy, all received radiotherapy (RT) with (n = 32) or without chemotherapy (n = 20). Median RT dose was 36 Gy (range, 6-50 Gy). Results Six (11%) patients progressed locally and 22 (42%) had a systemic relapse. At last follow-up, 28 patients were alive and 24 had died. The 5-year overall survival, disease-free survival, and local control were 69%, 57%, and 88%, respectively. In univariate analyses, favorable prognostic factors were younger age and complete neurologic response. Multivariate analysis showed that combined modality treatment, RT volume, total dose more than 36 Gy, tumor resection, and complete neurologic response were favorable prognostic factors. Conclusions Primary spinal epidural lymphoma has distinct clinical features and outcome, with a relatively good prognosis. After therapy, local control is excellent and systemic relapse occurs in less than half the cases. Combined modality treatment appears to be superior to RT alone

  11. Tumor Volume Reduction Rate After Preoperative Chemoradiotherapy as a Prognostic Factor in Locally Advanced Rectal Cancer

    International Nuclear Information System (INIS)

    Purpose: To investigate the prognostic significance of tumor volume reduction rate (TVRR) after preoperative chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC). Methods and Materials: In total, 430 primary LARC (cT3–4) patients who were treated with preoperative CRT and curative radical surgery between May 2002 and March 2008 were analyzed retrospectively. Pre- and post-CRT tumor volumes were measured using three-dimensional region-of-interest MR volumetry. Tumor volume reduction rate was determined using the equation TVRR (%) = (pre-CRT tumor volume − post-CRT tumor volume) × 100/pre-CRT tumor volume. The median follow-up period was 64 months (range, 27–99 months) for survivors. Endpoints were disease-free survival (DFS) and overall survival (OS). Results: The median TVRR was 70.2% (mean, 64.7% ± 22.6%; range, 0–100%). Downstaging (ypT0–2N0M0) occurred in 183 patients (42.6%). The 5-year DFS and OS rates were 77.7% and 86.3%, respectively. In the analysis that included pre-CRT and post-CRT tumor volumes and TVRR as continuous variables, only TVRR was an independent prognostic factor. Tumor volume reduction rate was categorized according to a cutoff value of 45% and included with clinicopathologic factors in the multivariate analysis; ypN status, circumferential resection margin, and TVRR were significant prognostic factors for both DFS and OS. Conclusions: Tumor volume reduction rate was a significant prognostic factor in LARC patients receiving preoperative CRT. Tumor volume reduction rate data may be useful for tailoring surgery and postoperative adjuvant therapy after preoperative CRT.

    Brain metastasis (BM) in patients with breast cancer is a catastrophic event that results in poor prognosis. Identification of prognostic factors associated with breast cancer brain metastases (BCBM) could help to identify patients at risk. The aim of this study was to assess clinical characteristics, prognostic factors, and survival of patients with BCBM who had craniotomy and resection in a series of patients treated with modern multimodality therapy. We analyzed 42 patients with BCBM who underwent resection. Patients were diagnosed with breast cancer between April 1994 and May 2010. Cox proportional hazards regression was selected to describe factors associated with time to BM, survival from the date of first recurrence, and overall survival (OS). Median age was 51 years (range 24-74). Median follow-up was 4.2 years (range 0.6-18.5). The proportion of the biological subtypes of breast cancer was ER+/HER2- 25%, ER+/HER2+ 15%, ER-/HER2+ 30%, and ER-/HER2- 30%. Median OS from the date of primary diagnosis was 5.74 years. Median survival after diagnosis of BM was 1.33 years. In multivariate Cox regression analyses, stage was the only factor associated with shorter time to the development of BM (P = 0.033), whereas age was the only factor associated with survival from the date of recurrence (P = 0.027) and with OS (P = 0.037). Stage at primary diagnosis correlated with shorter time to the development of BM, while age at diagnosis was associated with shorter survival in BCBM. None of the other clinical factors had influence on survival.

    Objective: To study the relationship between the Survivin expression and the histological grade, status of ER,expression of PS2 and the prognosis of patients with primary invasive breast cancer. Method: By using LSAB and SP immunohistochemical method, the expression of Survivin, PS2 and ER in 95 cases of invasive breast cancer were detected.Results: the positive rate of Survivin was 70.5% (67/95) and the expression of Survivin was positively related to the histological grade and status of PS2 and ER. The survival time after operation of patients without expression of Survivin was longer than those with positive Survivin. Conclusion: These data suggest that Survivin expression may be considered as a new unfavorable prognostic factor of breast cancer.

    AIM:To investigate the expression of vascular endothelial growth factor (VEGF) and calcium-binding protein S100A4 in pancreatic cancer and their relationship to the clinicopathological parameters and prognosis of pancreatic cancer.METHODS: Expression status of VEGF and S100A4 was examined in 62 surgical specimens of primary pancreatic cancer by immunohistochemistry. Correlation between the expression of VEGF and S100A4 and clinicopathological parameters was analyzed.RESULTS: Thirty-eight of 62 (61.3%) specimens of primary pancreatic cancer were positive for S100A4. Thirty-seven (59.7%) specimens showed positive expression of VEGF. The positive correlation between S100A4 and VEGF expression was significant in cancer tissues(P < 0.001). S100A4 expression was significantly correlated with tumor size, TNM stage and poorer prognosis. VEGF expression had a significant correlation with poorer prognosis. The prognosis of 17 S100A4- and VEGF-negative cancer patients was significantly better than that of other patients (P < 0.05). Distant metastasis(P = 0.001), S100A4- (P = 0.008) and VEGF-positive expression (P= 0.016) were significantly independent prognostic predictors (P<0.05).CONCLUSION: Over-expression of S100A4 and VEGF plays an important role in the development of pancreatic cancer. Combined examination of the two molecules might be useful in evaluating the outcome of patients with pancreatic cancer.

    Full Text Available Background and objective As there is a sharp increase in the incidence of lung cancer in women in recent years, it has brought broad concerns with its unique clinical and epidemiological characteristics and better prognosis. The aim of this study is to analyze the clinical data of women with advanced non-small cell lung cancer (NSCLC retrospectively to explore the prognostic factors. Methods Clinical data of 541 female patients with advanced NSCLC were collected and followed up till death. The primary endpoint is overall survival (OS. SPSS 11.0 statistical analysis software was used for univariate and multivariate analysis. Results The mean age is 59 years (20 years-86 years, adenocarcinoma account for 80.2% (434/541. The median OS was 15 months (95%CI: 13.87-16.13, and 1, 2, 5-year survival rates were 58.8%, 23.7% and 3.20% respectively. Univariate analysis showed that clinical stage, ECOG score, weight loss, clinical symptoms, liver/bone/brain metastasis and received more than one chemotherapy regimen, good response to the first-line chemotherapy, EGFR-TKI targeted therapy and radiotherapy treatment were significantly correlated with the OS and survival rate (P < 0.05. Combined with multivariate analysis, weight loss before treatment, ECOG score, received EGFR-TKI targeted therapy and response to first-line chemotherapy were independent prognostic factor for survival (P < 0.05. Conclusion There is a higher percentage of adenocarcinoma in female NSCLC. Weight loss before treatment, ECOG score, EGFR-TKI targeted therapy and response to first-line chemotherapy may become independent prognostic factors for survival of female patients with advanced NSCLC.

  18. Intraoperative radiotherapy combined with resection for pancreatic cancer. Analysis of survival rates and prognostic factors

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the efficiency of intraoperative radiotherapy (IORT) combined with surgical resection. Subjects were consecutive 69 patients with pancreatic cancer treated with surgery alone (n=31) or surgical resection combined with IORT (n=38) in a 13 year period between 1991 and 2003. We evaluated the effects of IORT against local recurrence of cancer and patients' survival, retrospectively. Furthermore, clinicopathological factors affecting the 5-year survival rate in the two groups were comparatively investigated. The IORT group showed a significantly lower local recurrence rate of cancer than that in the surgery alone group (7.8% and 22.6%, respectively; p<0.05). The 5-year survival probability in the IORT group was significantly higher than that in the surgery alone group (29.9% and 3.4%, respectively; p<0.05). According to the Japanese classification of pancreatic cancer, cancers located in the pancreas body or tail, no local residual cancer post operative procedure (R0), low grade local cancer progression (t1, 2), and low grade intrapancreatic neural invasion (ne0, 1) were significantly better prognostic factors in the IORT group than those in the surgery alone group. There were no significant differences between the both groups in the 5-year survival rate in terms of the sex of the patients, cancer of the pancreas head, histological type, more than R1, the presence of lymph node involvement, ne2-3, and clinical stages. IORT is a useful intraoperative adjuvant therapy for pancreatic cancer, when the curative resection is achieved. Our data have suggested that IORT suppresses the local recurrence of cancer and provides the significant survival benefit for those patients. (author)

    Objective The purpose of this study was to evaluate the distribution of vascular endothelial growth factor (VEGF) and CD105-microvessel density (MVD) in invasive breast carcinomas. We also aimed to analyze the relationship between VEGF and MVD expression with other standard prognostic parameters associated with invasive breast cancer, such as size, grade, stage of the cancer, metastases, and tumor recurrence. Methods Immunohistochemistry via the Ultra SensitiveTM S-P method was used to detect VEGF and MVD expression in 128 cases of invasive breast carcinoma. Specimens were evaluated for CD105 expres-sion. Positively stained microvessels were counted in dense vascular foci under 400× magnification. MVD in the peripheral area adjacent to the lesion and in the central area within the lesion in invasive breast carcinomas and benign leisions groups were also assessed. Fifty cases of benign breast disease tissue were selected as the control group. Results Results showed that 64.1% of invasive breast cancer samples were VEGF-positive, higher than in benign breast disease tissue (22.0%, P 0.05). MVD of the peripheral area adja-cent to the lesion was significantly higher than those central area within the lesion in both invasive breast cancer and benign breast disease groups (P 50 years) or the two tumor diameter groups (≤2 cm vs.>2 cm), P > 0.05. Conclusion Overexpression of VEGF and MVD may be important biological markers for invasion and lymph node and distant metastases of invasive breast cancer. Combined detection of the two tumor mark-ers could provide better prognostic monitoring for disease recurrence and metastasis, as wel as aid with clinical staging of breast tumors. Prediction of the risk for metastasis and recurrence, as wel as recurrence patterns based on VEGF and MVD post-surgery, could aid design of better fol ow-up regimens and appro-priate treatment strategies for breast cancer patients.

    2002-01-01

    Full Text Available In gynecologic oncology valid prognostic factors are necessary to define biologically similar subgroups for analysis of therapeutic efficacy. This study is the first published prospective study concerning prognostic significance of DNA ploidy and S‐phase fraction in cervical and endometrial cancer following enrichment of tumor cells by cytokeratin labelling. Epithelial cells were labeled by FITC‐conjugated cytokeratin antibody (CK 5, 6, 8, and CK 17 prior to flow cytometric cell cycle analysis in 91 specimens of cervical cancer and 73 samples of endometrial cancer. In cervical cancer neither DNA‐ploidy nor S‐phase fraction were relevant prognostic parameters. But CV of the G0G1‐peak showed prognostic relevance in cervical cancer cells, even in multivariate analysis. This interesting observation, however, seems to have no therapeutic consequence due to the small discrimination capacity of CV. In endometrial carcinoma, gross DNA‐aneuploidy (DNA‐index > 1.3 and a high percentage of proliferating cells (>75th percentile were univariate and multivariate highly significant prognostic factors for recurrence‐free survival. Especially DNA‐aneuploidy (DI>1.3 is one of the most important independent molecular biological prognostic factors. While diagnostic curettage we could identify risk patients even preoperatively by determination of the prognostic factors like histologic tumor type, grading, cervical involvement and DNA‐ploidy. Thereby these patients could be treated primarily in an oncologic center. In conclusion, our investigations showed that the determination of DNA‐ploidy should be done in endometrial carcinoma. In cervical cancer no clinical significance for determination of DNA‐parameters was found.

    Full Text Available Research objective: To study the role of prognostic factors in the estimation of risk development of recurrent prostate cancer after treatment by high-intensive focused ultrasound (HIUF. Objects and Research Methods: The research has included 102 patients with morphologically revealed localized prostate cancer by biopsy. They have been on treatment in Clinic of Urology of the Saratov Clinical Hospital n.a. S. R. Mirotvortsev. 102 sessions of initial operative treatment of prostate cancer by the method of HIFU have been performed. The general group of patients (n=102 has been subdivided by the method of casual distribution into two samples: group of patients with absent recurrent tumor and group of patients with the revealed recurrent tumor, by morphological research of biopsy material of residual prostate tissue after HIFU. The computer program has been used to study the signs of outcome of patients with prostate cancer. Results: Risk of development of recurrent prostate cancer has grown with the PSA level raise and its density. The index of positive biopsy columns <0,2 has shown the recurrence of prostate cancer in 17% cases while occurrence of prostate cancer in 59% cases has been determined by the index of 0,5 and higher. The tendency to obvious growth of number of relapses has been revealed by the sum of Glison raise with present perineural invasion. Cases of recurrent prostate cancer have been predominant in patients with lymphovascular invasions. In conclusion it has been worked out that the main signs of recurrent prostate cancer development may include: PSA, PSA density, the sum of Glison, lymphovascular invasion, invasion.

    Background The finding of new biomarkers is needed to have a better sub-classification of primary renal tumors (RCC) as well as more reliable predictors of outcome and therapy response. In this study, we evaluated the role of circulating FGF21, an endocrine factor, as a diagnostic and prognostic biomarker for ccRCC. Materials and Methods Serum samples from healthy controls (HC), clear cell and chromophobe RCC cancer patients were obtained from the serum biobank “Biobanco Público de Muestras Séricas Oncológicas” (BPMSO) of the “Instituto de Oncología “Ángel H. Roffo”. Serum FGF21 and leptin were measured by ELISA while other metabolic markers were measured following routinely clinical procedures. Results One of our major findings was that FGF21 levels were significantly increased in ccRCC patients compared with HC. Moreover, we showed an association between the increased serum FGF21 levels and the shorter disease free survival in a cohort of 98 ccRCC patients, after adjustment for other predictors of outcome. Conclusion Our results suggest that higher FGF21 serum level is an independent prognostic biomarker, associated with worse free-disease survival. PMID:27358750

    Full Text Available Abstract Background With the growing number of public repositories for high-throughput genomic data, it is of great interest to combine the results produced by independent research groups. Such a combination allows the identification of common genomic factors across multiple cancer types and provides new insights into the disease process. In the framework of the proportional hazards model, classical procedures, which consist of ranking genes according to the estimated hazard ratio or the p-value obtained from a test statistic of no association between survival and gene expression level, are not suitable for gene selection across multiple genomic datasets with different sample sizes. We propose a novel index for identifying genes with a common effect across heterogeneous genomic studies designed to remain stable whatever the sample size and which has a straightforward interpretation in terms of the percentage of separability between patients according to their survival times and gene expression measurements. Results The simulations results show that the proposed index is not substantially affected by the sample size of the study and the censoring. They also show that its separability performance is higher than indices of predictive accuracy relying on the likelihood function. A simulated example illustrates the good operating characteristics of our index. In addition, we demonstrate that it is linked to the score statistic and possesses a biologically relevant interpretation. The practical use of the index is illustrated for identifying genes with common effects across eight independent genomic cancer studies of different sample sizes. The meta-selection allows the identification of four genes (ESPL1, KIF4A, HJURP, LRIG1 that are biologically relevant to the carcinogenesis process and have a prognostic impact on survival outcome across various solid tumors. Conclusion The proposed index is a promising tool for identifying factors having a

    Full Text Available Abstract Background AIB1 (amplified in breast cancer I is a member of the p160 steroid receptor coactivator family. AIB1 is frequently overexpressed in breast cancer and has functions that promote oncogenesis that are independent of estrogen receptor (ER coactivation. We investigated prognostic significance of AIB1 and relationship between AIB1 and ER, progesterone receptor (PR, androgen receptor (AR, DAX-1, and HER2. Methods RNA in situ hybridization (ISH and immunohistochemical (IHC staining for AIB1, IHC staining for ER and the progesterone receptor (PR and IHC staining and silver in situ hybridization (SISH for HER2 were performed for 185 breast cancer cases. Results A high level of expression of AIB1 mRNA was observed in 60.0% of tumors. IHC analysis detected AIB1 positivity in 47.3% of tumors, which did not correlate with AIB1 mRNA expression (p = 0.24, r = 0.10. AIB1 protein expression correlated with AR and DAX-1 expression (p = 0.01, r = 0.22 and p = 0.02, r = 0.21, respectively but not with ER or PR expression (p = 0.14, r = -0.13 and p = 0.16, r = -0.12, respectively. AIB1 protein expression correlated with the amplification of the HER2 gene (p = 0.03, r = 0.19. In contrast to AIB1 protein expression, AIB1 mRNA expression did not correlate with AR, DAX-1, ER, and PR expression, and the amplification of the HER2 gene (p > 0.05 for all. There were trends that strong AIB1 protein expression correlated with poorer disease free survival (p = 0.07. Strong AIB1 protein expression correlated with poorer overall survival (p = 0.04. Among the ER-negative subgroup, strong AIB1 protein expression correlated with poorer disease free survival and overall survival (p = 0.01 and p Conclusions Strong AIB1 protein expression was poor prognostic factor in breast cancer, especially in ER-negative breast cancers. Further investigation is essential to determine whether AIB1 might be effective therapeutic targets for ER-negative breast cancers.

    Objective:The purpose of the study was to assess prognostic factors to predict overal survival (OS) and progres-sion-free survival (PFS) in non-smal-celllung cancer (NSCLC) with brain metastasis (BM). Methods:From November 2011 to March 2013, the clinical data of 31 NSCLC cases with BM treated with multiple modalities including brain radiotherapy alone, systemic chemotherapy, whole brain radiotherapy (WBRT) combined with tyrosine kinase inhibitor (TKIs). The ef icacy and adverse reaction were evaluated after treatment. Results:In terms of intracranial lesions, the objective response rate (ORR) and the disease control rate (DCR) were 22.6%and 90.3%, respectively. As for systemic disease, ORR and DCR were 32.3%and 93.5%, respectively. The median time to progression-free survival (PFS) was 298 days (95%CI:258.624-337.376 days), whereas in the epidermal growth factor receptor (EGFR) mutation patients was 331 days. Patients who received EGFR-TKIs combined with brain radiation had better response rate (RR) than those only brain radiation. Univariate analysis showed that the EGFR-mutations could predictive factors for PFS, and not to other clinical pathological features. The most common toxici-ties were rash and diarrhea, but al were wel-tolerated. Conclusion:EGFR-mutations is the independent prognostic factors af ecting the survival rates of NSCLC patients with BM. Through the clinical observation, icotinib combined with WBRT may be ef ective on brain metastases in NSCLC patients, and toxicities are tolerable, which worth further study.

    Full Text Available To evaluate the prognostic factors and indexes of a series of 93 patients with breast cancer and brain metastases (BM in a single institution. Treatment outcomes were evaluated according to the major prognostic indexes (RPA, BSBM, GPA scores and breast cancer subtypes. Independent prognostic factors for overall survival (OS were identified. The median OS values according to GPA 0–1, 1.5–2, 2.5–3 and 3.5–4, were 4.5, 9.5, 14.2 and 19.1 months, respectively (p < 0.0001 and according to genetic subtypes, they were 5, 14.2, 16.5 and 17.1 months for basal-like, luminal A and B and HER, respectively (p = 0.04. Using multivariate analysis, we established a new grading system using the six factors that were identified as indicators of longer survival: age under 60 (p = 0.001, high KPS (p = 0.007, primary tumor control (p = 0.05, low number of extracranial metastases and BM (p = 0.01 and 0.0002, respectively and triple negative subtype (p = 0.002. Three groups with significantly different median survival times were identified: 4.1, 9.5 and 26.3 months, respectively (p < 0.0001. Our new grading system shows that prognostic indexes could be improved by using more levels of classification and confirms the strength of biological prognostic factors.

    * A. Tavakoli, M.D

    Full Text Available Abstract Background and purpose: The breast cancer is the most common malignancy in women. Bcl-2 expression has been determined in more than half of the cases of breast cancer. The purpose of this study was to determine the expression of bcl-2 gene in primary breast cancer and its correlation with grade, stage and axillary lymph node involvement.Materials and Methods: The study was a cross-sectional one that was performed on 75 patients with breast cancer admitted to Mostafa Khomeini hospital (2000-2005. After preparing the samples, a tissue section from each sample was obtained. One of the tumoral sections and one of the lymph node sections were stained using H & E. We determined the type of the tumor, the number of lymph nodes, the stage and the grade of the tumor. We studied Bcl-2 with polyclonal antibody by IHC.Results: Our study showed that 69.3% of patients had hymph node involvment. In addition, 41.3% of samples were positive for Bcl-2, 58.7% of samples were in stage II and many patients (42.7% were in grade III. In this study, we didn’t find any relationship between bcl-2 and stage and lymph node involvment. We also found a significant association between bcl-2 and grade (P<0.006. Also, high bcl-2 expression was more frequent in high-grade tumor.Conclusion: According to the results obtained from earlier studies and our study, it seems that bcl2 is a prognostic factor in breast cancer. But further investigations with more specimens and long-time follow-up are required to clarify the exact role of Bcl-2 in the prognosis of breast cancer.

  11. Prognostic factors and patterns of failure in pathologic stage II endometrial cancer

    International Nuclear Information System (INIS)

    Purpose: Numerous studies have identified prognostic factors and failure patterns in stage I and clinical stage II endometrial cancer. These issues are less defined in pathologic stage II disease (pII) due to a paucity of patient data. Herein, we describe the prognostic significance of patient and tumor factors and patterns of failure in patients with pII disease. Methods/Materials: Fifty-three pts with pII (38 pIIA, 15 pIIB) endometrial cancer were treated between (6(80)) and (6(95)). Median age was 63 years (range, 35-90). Thirty-four pts (64%) were White, 16 (30%) Black and 3 (6%) Hispanic. Most tumors were pure adenocarcinoma (ACA) (66%) and grade 2-3 (77%). All patients underwent TAH-BSO. Nodal sampling and peritoneal washings were performed in 72% and 76%, respectively. Forty-eight (91%) received postoperative external beam pelvic (EBRT) +/- intracavitary RT (ICRT). Patient age ( 60), race (black vs other), stage (pIIA v pIIB), histology (ACA v other), myometrial invasion ( 50%) and grade ((1(2)) v 3) were evaluated. Sites of failure were defined as vaginal cuff, pelvis, para-aortic, and distant. Median followup was 40 months (range, 11-159 months) with 25% of pts followed for > 10 years. Results: The 5-year actuarial vaginal (VC), pelvic (PC) and para-aortic (PAC) controls for the entire group were 86.2%, 95.4% and 89.2%, respectively. The 5-year distant-free (DistFS), disease-free (DFS) and cause-specific (CSS) survivals were 79.6%, 63.7% and 77.5%, respectively. Conclusion: Our results demonstrate the prognostic significance of race and myometrial invasion as well as confirm the significance of stage, histology and grade in pII disease. Postoperative RT is associated with excellent locoregional control in these pts with the predominance of failure in para-aortic and distant sites

    The data regarding the prognostic significance of EGFR (epidermal growth factor receptor) expression and adjuvant therapy in patients with resected pancreatic cancer are insufficient. We retrospectively investigated EGFR status in 357 resected PDAC (pancreatic duct adenocarcinoma) patients using tissue immunohistochemistry and validated the possible role of EGFR expression in predicting prognosis. The analysis was based on excluding the multiple confounding parameters. A negative association was found between overall EGFR status and postoperative survival (p = 0.986). Remarkably, adjuvant chemotherapy and radiotherapy were significantly associated with favorable postoperative survival, which prolonged median overall survival (OS) for 5.8 and 10.2 months (p = 0.009 and p = 0.006, respectively). Kaplan-Meier analysis showed that adjuvant chemotherapy correlated with an obvious survival benefit in the EGFR-positive subgroup rather than in the EGFR-negative subgroup. In the subgroup analyses, chemotherapy was highly associated with increased postoperative survival in the EGFR-negative subgroup (p = 0.002), and radiotherapy had a significant survival benefit in the EGFR-positive subgroup (p = 0.029). This study demonstrated that EGFR expression is not correlated with outcome in resected pancreatic cancer patients. Adjuvant chemotherapy and radiotherapy were significantly associated with improved survival in contrary EGFR expressing subgroup. Further studies of EGFR as a potential target for pancreatic cancer treatment are warranted. PMID:27399694

  13. Hypoxia-inducible factor 1 alpha in high-risk breast cancer: an independent prognostic parameter?

    International Nuclear Information System (INIS)

    Hypoxia-inducible factor 1 alpha (hif-1α) furnishes tumor cells with the means of adapting to stress parameters like tumor hypoxia and promotes critical steps in tumor progression and aggressiveness. We investigated the role of hif-1α expression in patients with node-positive breast cancer. Tumor samples from 77 patients were available for immunohistochemistry. The impact of hif-1α immunoreactivity on survival endpoints was determined by univariate and multivariate analyses, and correlations to clinicopathological characteristics were determined by cross-tabulations. hif-1α was expressed in 56% (n = 43/77) of the patients. Its expression correlated with progesterone receptor negativity (P = 0.002). The Kaplan–Meier curves revealed significantly shorter distant metastasis-free survival (DMFS) (P = 0.04, log-rank) and disease-free survival (DFS) (P = 0.04, log-rank) in patients with increased hif-1α expression. The difference in overall survival (OS) did not attain statistical significance (5-year OS, 66% without hif-1α expression and 55% with hif-1α expression; P = 0.21). The multivariate analysis failed to reveal an independent prognostic value for hif-1α expression in the whole patient group. The only significant parameter for all endpoints was the T stage (T3/T4 versus T1/T2: DMFS, relative risk = 3.16, P = 0.01; DFS, relative risk = 2.57, P = 0.03; OS, relative risk = 3.03, P = 0.03). Restricting the univariate and multivariate analyses to T1/T2 tumors, hif-1α expression was a significant parameter for DFS and DMFS. hif-1α is expressed in the majority of patients with node-positive breast cancer. It can serve as a prognostic marker for an unfavorable outcome in those with T1/T2 tumors and positive axillary lymph nodes

    Full Text Available Breast cancer recurrence (BCR is a common treatment outcome despite curative-intent primary treatment of non-metastatic breast cancer. Currently used prognostic and predictive factors utilize tumor-based markers, and are not optimal determinants of risk of BCR. Germline-based copy number aberrations (CNAs have not been evaluated as determinants of predisposition to experience BCR. In this study, we accessed germline DNA from 369 female breast cancer subjects who received curative-intent primary treatment following diagnosis. Of these, 155 experienced BCR and 214 did not, after a median duration of follow up after breast cancer diagnosis of 6.35 years (range = 0.60-21.78 and 8.60 years (range = 3.08-13.57, respectively. Whole genome CNA genotyping was performed on the Affymetrix SNP array 6.0 platform. CNAs were identified using the SNP-Fast Adaptive States Segmentation Technique 2 algorithm implemented in Nexus Copy Number 6.0. Six samples were removed due to poor quality scores, leaving 363 samples for further analysis. We identified 18,561 CNAs with ≥1 kb as a predefined cut-off for observed aberrations. Univariate survival analyses (log-rank tests identified seven CNAs (two copy number gains and five copy neutral-loss of heterozygosities, CN-LOHs showing significant differences (P<2.01×10(-5 in recurrence-free survival (RFS probabilities with and without CNAs.We also observed three additional but distinct CN-LOHs showing significant differences in RFS probabilities (P<2.86×10(-5 when analyses were restricted to stratified cases (luminal A, n = 208 only. After adjusting for tumor stage and grade in multivariate analyses (Cox proportional hazards models, all the CNAs remained strongly associated with the phenotype of BCR. Of these, we confirmed three CNAs at 17q11.2, 11q13.1 and 6q24.1 in representative samples using independent genotyping platforms. Our results suggest further investigations on the potential use of germline DNA

    2011-03-01

    Thromboxane synthase (TXS) metabolises prostaglandin H2 into thromboxanes, which are biologically active on cancer cells. TXS over-expression has been reported in a range of cancers, and associated with a poor prognosis. TXS inhibition induces cell death in-vitro, providing a rationale for therapeutic intervention. We aimed to determine the expression profile of TXS in NSCLC and if it is prognostic and\\/or a survival factor in the disease.

Methods: Pain characteristics, the effectiveness, and prognostic factors for pain control were analyzed in 152 patients with lung cancer having moderate or severe chronic pain admitted to Cancer Center of The First Hospital of Jilin University, People’s Republic of China, between January 2012 and May 2013. Information about sex, age, pathological type, TNM stage, presence/absence of bone metastases, characteristics of pain, methods, and effectiveness of pain management was recorded. Results: Patients with non-small-cell lung cancer and small-cell carcinoma accounted for 132/152 (86.8% and 20/152 (13.2% cases, respectively. Among them, moderate (72.4% or severe pain (27.6% was reported in 73.7% of the cases at stage IV, chest or back pain was reported in 76.3% of the cases, and pain in other locations in the rest of the cases. Bone metastases were apparent in 44.1% of the patients. Neuropathic pain was noted in 46.7% of the patients, and frequent breakthrough pain was noted in 25.7% of the patients. High pain intensity was associated with frequent breakthrough pain. Pain was adequately controlled in 81.6% of the patients prescribed 3 days of analgesics. More patients reported a KPS higher than or equal to 80 after 3 days of analgesic treatment (P<0.001. Severe pain, frequent breakthrough pain, and presence of bone metastases were independent risk factors for poor pain control.

The marker most extensively associated with breast cancer is MUC1. The objective of the study was to analyze prognostic and risk factors in relation to tumor markers in order to clarify breast cancer biology. A total of 349 primary tumor samples and lymph nodes from breast cancer patients were studied. Risk and prognostic factors were considered. An immunohistochemical approach was applied and an extensive statistical analysis was performed, including frequency analysis and analysis of variance. Correlation among variables was performed with principal component analysis.Results: All the antigens showed an increased expression according to tumor size increment; moreover, sialyl Lewis x expression showed a significant increase in relation to disease stage, whereas Tn and TF presented a positive tendency. Vascular invasion was related to sialyl Lewis x expression and number of metastatic lymph nodes. Taking into account risk factors, when a patient had at least one child, Lewis antigens diminished their expression. In relation to breastfeeding, sialyl Lewis x expression diminished, although its apical expression increased.Conclusion: Associations between MUC1 and carbohydrate antigens and risk and prognostic factors show the complexity of the cellular biological behavior that these antigens modulate in breast cancer.Keywords: breast cancer, Argentine women, risk factors, prognostic factors, antigenic expression

    Purpose: To provide further understanding regarding outcome and prognostic factors of endometrial stromal tumors (EST). Methods and Materials: A retrospective analysis was performed on the records of 59 women diagnosed with EST and treated with curative intent between 1983 and 2007 in the framework of the Rare Cancer Network. Results: Endometrial stromal sarcomas (ESS) were found in 44% and undifferentiated ESS (UES) in 49% of the cases. In 7% the grading was unclear. Of the total number of patients, 33 had Stage I, 4 Stage II, 20 Stage III, and 1 presented with Stage IVB disease. Adjuvant chemotherapy was administered to 12 patients, all with UES. External-beam radiotherapy (RT) was administered postoperatively to 48 women. The median follow-up was 41.4 months. The 5-year overall survival (OS) rate was 96.2% and 64.8% for ESS and UES, respectively, with a corresponding 5-year disease-free survival (DFS) rate of 49.4% and 43.4%, respectively. On multivariate analysis, adjuvant RT was an independent prognostic factor for OS (p = 0.007) and DFS (p = 0.013). Locoregional control, DFS, and OS were significantly associated with age ({<=}60 vs. >60 years), grade (ESS vs. UES), and International Federation of Gynecology and Obstetrics stage (I-II vs. III-IV). Positive lymph node staging had an impact on OS (p < 0.001). Conclusion: The prognosis of ESS differed from that of UES. Endometrial stromal sarcomas had an excellent 5-year OS, whereas the OS in UES was rather low. However, half of ESS patients had a relapse. For this reason, adjuvant treatment such as RT should be considered even in low-grade tumors. Multicenter randomized studies are still warranted to establish clear guidelines.

    2012-02-01

    Objectives: Laser cordectomy is very popular nowadays and become one of the treatments of choice for early glottis carcinoma. Transoral laser microsurgery has many advantages comparing conventional open surgery or radiation therapy. In this study, we examined the oncologic results of laser cordectomy for early glottic cancer and analyzed the prognostic impact on the survival of the several tumor-related and treatment-related factors. Methods: Patients who were diagnosed as early glottic squamous cell carcinoma, treated by laser cordectomy with curative intent were analyzed. Patients with preivous radiation therapy were included. From June 1988 to March 2005, 202 patients from five hospitals were analyzed (174 T1, 28 T2). Results: Five-year overall survival and disease-free survival were 98.4% and 84.9%. Twenty two patients developed local recurrence. Total laryngectomy was done in 6 patients and laryngeal preservation rate was 97%. Recurrence was higher in the patients with anterior commissure involvement (9/39) than without anterior commissure involvement (13/163). Recurrence was higher in T1b (4/15) than T1a (13/159). Previous radiation was also highly related to the recurrence (7/20 vs 15/182). Twenty patients with local recurrence after radiation therapy were treated by salvage laser cordectomy. Of them, 7 patients developed local recurrence and 5 year disease-free survival was 57%. Complication was rare with one case of hemorrhage. Tracheotomy was not necessary in all patients. Conclusions: Laser cordectomy for early glottic carcinoma showed high survival, laryngeal preservation rate and low complication rate. The prognostic factors were anterior commissure involvement, both vocal fold involvement and previous radiotherapy.

    To identify prognostic factors for disease progression and survival of patients with extracranial oligometastatic breast cancer (EOMBC), and to investigate the role of radiation therapy (RT) for metastatic lesions. We retrospectively reviewed the medical records of 50 patients who had been diagnosed with EOMBC following standard treatment for primary breast cancer initially, and received RT for metastatic lesions, with or without other systemic therapy between January 2004 and December 2008. EOMBC was defined as breast cancer with five or less metastases involving any organs except the brain. All patients had bone metastasis (BM) and seven patients had pulmonary, hepatic, or lymph node metastasis. Median RT dose applied to metastatic lesions was 30 Gy (range, 20 to 60 Gy). The 5-year tumor local control (LC) and 3-year distant progression-free survival (DPFS) rate were 66.1% and 36.8%, respectively. High RT dose (> or =50 Gy10) was significantly associated with improved LC. The 5-year overall survival (OS) rate was 49%. Positive hormone receptor status, pathologic nodal stage of primary cancer, solitary BM, and whole-lesion RT (WLRT), defined as RT whose field encompassed entire extent of disease, were associated with better survival. On analysis for subgroup of solitary BM, high RT dose was significantly associated with improved LC and DPFS, shorter metastasis-to-RT interval (< or =1 month) with improved DPFS, and WLRT with improved DPFS and OS, respectively. High-dose RT in solitary BM status and WLRT have the potential to improve the progression-free survival and OS of patients with EOMBC.

    Patients with metastatic spinal cord compression (MSCC) from non-small cell lung cancer (NSCLC) have an unfavorable prognosis compared to most other MSCC patients. This study was performed to identify prognostic factors for functional outcome and survival in these patients after radiotherapy (RT) alone. Data of 356 patients irradiated for MSCC from NSCLC were retrospectively analyzed. Ten potential prognostic factors were investigated including age, gender, Eastern cooperative Oncology Group performance score (ECOG-PS), number of involved vertebrae, pre-RT ambulatory status, other bone metastases, visceral metastases, interval from cancer diagnosis to RT of MSCC, time developing motor deficits before RT, and the radiation schedule. On multivariate analysis, better functional outcome was associated with pre-RT ambulatory status (estimate: -0.84, p = 0.022), no visceral metastases (estimate: -1.15, p < 0.001), interval from cancer diagnosis to RT of > 15 months (estimate: +0.48, p = 0.019), and slower (> 7 days) development of motor deficits (estimate: +1.56, p < 0.001). On multivariate analysis, improved survival was significantly associated with female gender (risk ratio (RR) 1.32, p = 0.043), ECOG-PS 1-2 (RR 1.45, p = 0.034), pre-RT ambulatory status (RR 0.58, p < 0.001), no other bone metastases (RR 1.38, p = 0.010), no visceral metastases (RR 2.87, p < 0.001), interval from cancer diagnosis to RT of > 15 months (RR 0.84, p = 0.035), and slower (> 7 days) development of motor deficits (RR 0.78, p < 0.001). This study identified additional independent prognostic factors for outcomes after radiotherapy of MSCC from NSCLC. These prognostic factors can be used for stratification in future trials and can help develop prognostic scores for MSCC from NSCLC. (orig.)

    Objective To evaluate the impact of extracapsular spread (ECS) in ipsilateral neck metastasis on prognosis and its related factors in laryngeal cancer.Methods The study included 184 patients who underwent laryngectomy and simultaneous radical or modified radical neck dissection between January 1994 and December 1997 for laryngeal cancer. All of them had a complete 5-year follow-up. We used transparent lymph node detection and continuous slicing method on all neck dissection specimens.Kaplan-Meier model was used for survival analysis and the log-rank test was used to assess significance.Results We found pathological neck metastases in 80 patients. Among them, 26 cases (32.5%) had ECS in ipsilateral neck. ECS incidence increased with advanced pathological N (pN) stages (pN1 3.7%, pN2a 25.0%, pN2b 50. 0%, and pN2c 55.6%; P=0.001). ECS incidence also increased with number of positive nodes ( 1 positive node 8.6%, 2 positive nodes 33.3%, 3 and more positive nodes 66. 7%; P<0.001). Incidences of contralateral neck metastases and ipsilateral neck recurrence in patients with ECS were higher than those in patients without ECS (46.2%vs.24. 1%, P=0 046; 34. 6% vs. 7.4%, P =0. 002). The 5-year survival rate of patients with ECS was significantly lower than that of patients without ECS (23.1% vs. 57.4%,P=0.013).Conclusion ECS is an important prognostic factor in laryngeal cancer. Patients with ECS have a higher incidence of contralateral neck metastasis, so bilateral neck dissection should be selected.

    The detection of circulating tumor cells (CTCs) in peripheral blood is currently an important field of study. Detection of CTCs by the OBP-401 assay (TelomeScan(®)) has previously been reported to be useful in the diagnosis, prognosis and evaluation of therapeutic efficacy in breast and gastric cancer. The aim of the present study was to evaluate the OBP-401 assay as a novel method of detecting CTCs of small cell lung cancer (SCLC) patients and to evaluate whether CTC count is associated with prognosis. Prospectively, 30 consecutively diagnosed SCLC patients who had commenced chemotherapy or chemoradiotherapy were enrolled as subjects of the current study. Peripheral blood specimens were collected from the SCLC patients prior to and following the initiation of treatment and the viable CTCs were detected in the specimens following incubation with a telomerase-specific, replication-selective, oncolytic adenoviral agent, which was carrying the green fluorescent protein gene. CTCs were detected in 29 patients (96%). The group of 21 patients with a CTC count of <2 cells/7.5 ml prior to treatment (baseline) had a significantly longer median survival time than the group of eight patients with a CTC count of ≥2 cells/7.5 ml prior to treatment (14.8 and 3.9 months, respectively; P=0.007). The results of a multivariate analysis showed that the baseline CTC count was an independent prognostic factor for survival time (hazard ratio, 3.91; P=0.026). Among the patients that achieved a partial response to treatment, patients who had a CTC count of <2 cells/7.5 ml following two cycles of chemotherapy tended to have a longer median progression-free survival compared with patients who had a CTC count of ≥2 cell/7.5 ml (8.3 and 3.8 months, respectively; P=0.07). Therefore, CTCs may be detected via OBP-401 assay in SCLC patients and the CTC count prior to treatment appears to be a strong prognostic factor. PMID:24765158

  12. Prognostic Factors in Stereotactic Body Radiotherapy for Non-Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To investigate the factors that influence clinical outcomes after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC). Methods and Materials: A total of 101 consecutive patients who underwent SBRT with 48 Gy in 4 fractions for histologically confirmed Stage I NSCLC were enrolled in this study. Factors including age, maximal tumor diameter, sex, performance status, operability, histology, and overall treatment time were evaluated with regard to local progression (LP), disease progression (DP), and overall survival (OS) using the Cox proportional hazards model. Prognostic models were built with recursive partitioning analysis. Results: Three-year OS was 58.6% with a median follow-up of 31.4 months. Cumulative incidence rates of LP and DP were 13.2% and 40.8% at 3 years, respectively. Multivariate analysis demonstrated that tumor diameter was a significant factor in all endpoints of LP, DP, and OS. Other significant factors were age in DP and sex in OS. Recursive partitioning analysis indicated a condition for good prognosis (Class I) as follows: female or T1a (tumor diameter ≤20 mm). When the remaining male patients with T1b-2a (>20 mm) were defined as Class II, 3-year LP, DP, and OS were 6.8%, 23.6%, and 69.9% in recursive partitioning analysis Class I, respectively, whereas these values were 19.9%, 58.3%, and 47.1% in Class II. The differences between the classes were statistically significant. Conclusions: Tumor diameter and sex were the most significant factors in SBRT for NSCLC. T1a or female patients had good prognosis.

    AIM: To clarify the expression patterns and prognostic implications of the mitotic regulator Polo-like kinase 1(PLK1) in colon cancer.METHODS: Expression of PLK1 was investigated by immunohistochemistry (158 cases) and immunoblotting in tissue of colon adenomas and adenocarcinomas. PLK1expression patterns were correlated with clinicopathological parameters and patient prognosis. In addition, expression of PLK1 was evaluated by immunoblot and PCR in colon carcinoma cell lines, and coexpression of PLK1 with the proliferation marker Ki-67 was investigated.RESULTS: Weak PLK1 expression was observed in normal colon mucosa and adenomas. In contrast, 66.7% of carcinomas showed strong expression of PLK1.Overexpression of PLK1 correlated positively with Dukes stage (P<0.001), tumor stage (P = 0.001) and nodal status (P<0.05). Additionally, PLK1 expression was a prognostic marker in univariate survival analysis (P<0.01) and had independent prognostic significance (RR = 3.3, P = 0.02)in patients with locoregional disease. Expression of PLK1 mRNA and protein was detected in all cell lines investigated. Coexpression of PLK1 and Ki-67 was observed in the majority of colon cancer cells, but a considerable proportion of cells showed PLK1 positivity without Ki-67expression.CONCLUSION: PLK1 is a new prognostic marker for colon carcinoma patients and may be involved in tumorigenesis and progression of colon cancer. Strategies focusing on PLK1 inhibition in vivo might therefore represent a promising new therapeutic approach for this tumor entity.

    To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment. In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the cystic duct and common hepatic duct as the dividing point. Locoregional failure sites were categorized as follows: the hepatoduodenal ligament and tumor bed, the celiac artery and superior mesenteric artery, and other sites. The median follow-up time was 29 months for surviving patients. Three-year locoregional progression-free survival, progression-free survival, and overall survival rates were 50%, 42%, and 52%, respectively. Regarding initial failures, 79% and 81% were locoregional failures in proximal and distal EBDC patients, respectively. The most common site was the hepatoduodenal ligament and tumor bed. In the multivariate analysis, perineural invasion was associated with poor locoregional progression-free survival (p = 0.023) and progression-free survival (p = 0.012); and elevated postoperative CA19-9 (> or =37 U/mL) did with poor locoregional progression-free survival (p = 0.002), progression-free survival (p < 0.001) and overall survival (p < 0.001). Both proximal and distal EBDC showed remarkable proportion of locoregional failure. Perineural invasion and elevated postoperative CA19-9 were risk factors of locoregional failure. In these patients with high risk of locoregional failure, adjuvant radiotherapy could be considered to improve locoregional control.

    Full Text Available Intratumor heterogeneity implies heterogeneous protein function, facilitating tumor adaptation which results in therapeutic failure. We hypothesized that tumor heterogeneity at protein level may influence the course of the disease. As a single biopsy might not represent the full biologic complexity of the tumor, we have analyzed immunohistochemically four different cores obtained from each primary tumor within the cohort of 364 patients with endometrial cancer (EC. The following proteins were examined: estrogen receptor 1 (ESR1, progesterone receptor, epidermal growth factor receptor, v-erb-b2 erythroblastic leukemia viral oncogene homolog 2, receptor tyrosine-protein kinase erbB-3, v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 4, phosphatidylinositol-4,5-bisphosphate 3-kinase, phosphorylated v-akt murine thymoma viral oncogene homolog 1, v-myc avian myelocytomatosis viral oncogene homolog, DNA topoisomerase II alpha 170 kDa (TOP2A, cyclin-dependent kinase inhibitor 2A (CDKN2A, tumor protein p53, RAD21 homolog, S. pombe, and runt-related transcription factor 1. Particularly strong correlation was found between TOP2A and CDKN2A heterogeneity and higher stage of the disease (P = .0002 and P = .0003, respectively. Most correlations with clinicopathologic data were observed for ESR1 heterogeneity that correlated with non-endometrioid carcinomas (P=.02, higher stage (P=.005, grade (P=.01, and the presence of metastases (P = .01. Thirty-nine (11.0% patients were classified as “globally heterogeneous”. Cumulative tumor heterogeneity strongly correlated with the presence of metastases, higher stage, and higher grade of the disease (all P b .05. It also carried negative prognostic value (P=.0008. We show that the degree of heterogeneity in EC might serve as a clinically valid molecular marker.

    BRCA1 promoter methylation is an essential epigenetic transcriptional silencing mechanism, related to breast cancer (BC) occurrence and progression. We quantified the methylation level of BRCA1 promoter and evaluated its significance as prognostic and predictive factor. BRCA1 promoter methylation level was quantified by pyrosequencing in surgical cancerous and adjacent normal specimens from 154 BC patients. A follow up of 98 months was conducted to assess the correlation between BRCA1-methylation level vs. overall survival (OS) and disease free survival (DFS). The mean methylation level in BC tissues was significantly higher (mean 32.6%; median 31.9%) than in adjacent normal samples (mean 16.2%; median 13.0%) (P Classification of grades and molecular subtypes did not show any prognostic significance. Pyrosequencing is a precise and efficient method to quantify BRCA1 promoter methylation level, with a high potential for future clinical implication, as it identifies subgroups of patients with poorer prognosis.

    To evaluate the results and prognostic factors for postoperative adjuvant radiation therapy in patients at stages I and II of endometrial cancer. Materials and Methods: Between January 1991 and December 2006, 35 patients with FIGO stages I and II disease, who received adjuvant radiation therapy following surgery for endometrial cancer at Ewha Womans University Hospital, were enrolled in this study. A total of 17 patients received postoperative pelvic external beam radiation therapy; whereas, 12 patients received vaginal brachytherapy alone, and 6 patients received both pelvic radiation therapy and vaginal brachytherapy. Results: The median follow-up period for all patients was 54 months. The 5-yr overall survival and disease-free survival rates for all patients were 91.4% and 81.7%, respectively. The 5-yr overall survival rates for low-risk, intermediate-risk, and high-risk groups were 100%, 100% and 55.6%, respectively. In addition, the 5-yr disease-free survival rates were 100%, 70.0%, and 45.7%, respectively. Although no locoregional relapses were identified, distant metastases were observed in 5 patients (14%). The most common site of distant metastases was the lung, followed by bone, liver, adrenal gland, and peritoneum. A univariate analysis revealed a significant correlation between distant metastases and risk-group (p=0.018), pathology type (p=0.001), and grade (p=0.019). A multivariate analysis also revealed that distant metastases were correlated with pathology type (p=0.009). Papillary, serous and clear cell carcinoma cases demonstrated a poor patient survival rate compared to cases of endometrioid adenocarcinoma or adenosquamous carcinoma. The most common complication of pelvic external beam radiation therapy was enteritis (30%), followed by proctitis, leucopenia, and lymphedema. All these complications were of RTOG grades 1 and 2; no grades 3 and 4 were observed. Conclusion: For the low-risk and intermediate-risk groups (stages 1 and 2) endometrial

    Computer-aided image analysis (CAI) can help objectively quantify morphologic features of hematoxylin-eosin (HE) histopathology images and provide potentially useful prognostic information on breast cancer. We performed a CAI workflow on 1,150 HE images from 230 patients with invasive ductal carcinoma (IDC) of the breast. We used a pixel-wise support vector machine classifier for tumor nests (TNs)-stroma segmentation, and a marker-controlled watershed algorithm for nuclei segmentation. 730 morphologic parameters were extracted after segmentation, and 12 parameters identified by Kaplan-Meier analysis were significantly associated with 8-year disease free survival (P < 0.05 for all). Moreover, four image features including TNs feature (HR 1.327, 95%CI [1.001-1.759], P = 0.049), TNs cell nuclei feature (HR 0.729, 95%CI [0.537-0.989], P = 0.042), TNs cell density (HR 1.625, 95%CI [1.177-2.244], P = 0.003), and stromal cell structure feature (HR 1.596, 95%CI [1.142-2.229], P = 0.006) were identified by multivariate Cox proportional hazards model to be new independent prognostic factors. The results indicated that CAI can assist the pathologist in extracting prognostic information from HE histopathology images for IDC. The TNs feature, TNs cell nuclei feature, TNs cell density, and stromal cell structure feature could be new prognostic factors.

  19. Is the presence of mammographic comedo calcification really a prognostic factor for small screen-detected invasive breast cancers?

    International Nuclear Information System (INIS)

    AIM: It has been suggested that the use of traditional prognostic factors such as histological grade and lymph node stage are not reliable predictors of outcome for small (2 = 9.68,P = 0.008). No significant association was demonstrated between the presence of comedo calcification and survival. Multivariate analysis confirmed lymph node stage as the only independent prognostic factor for these small screen-detected breast cancers (χ2 = 7.18,P = 0.007). There were significant associations between the presence of comedo calcification on the screening mammogram and high histological grade and small tumour size. CONCLUSION: Although the overall outcome for small screen-detected breast cancers (<15 mm diameter) is excellent, the presence of lymph node metastases is associated with a significant reduction in long-term survival. The presence of mammographic comedo calcification is not an independent prognostic factor, but is closely related to histological grade. James, J. J. et al. (2003). Clinical Radiology, 58, 54-62

    Although a number of studies have indicated that the positive expression of nucleophosmin (NPM) and trefoil factor 3 (TFF3) is associated with oncogenesis and poor prognosis in several tumor types, the prognostic value of the co-expression of NPM and TFF3 in gastric cancer (GC) has not been fully elucidated. Therefore, in this study, we aimed to investigate the role of NPM and TFF3 in GC and determine their prognostic value. We retrospectively reviewed 108 patients who had undergone radical gastric tumor resection. The expression of NPM and TFF3 was detected by immunohistochemistry and the association of NPM and TFF3 with clinicopathological characteristics was investigated using the Chi-square test. Furthermore, univariate and multivariate analyses were conducted to determine the prognostic value of these markers. Of the 108 samples, NPM was positive in 57 (53%) and TFF3 was positive in 54 samples (50%). The positive expression of NPM was correlated with advanced tumor stage and recurrence (P=0.0333 and PTFF3 was associated with larger tumor size (P=0.0005), poor differentiation (P=0.0435), lymph node metastasis (P=0.0116), advanced tumor stage (P=0.0244) and recurrence (P=0.0116). The univariate analysis revealed that the expression of NPM, the expression of TFF3 and the co-expression of the two were associated with poor survival (P=0.0004, 0.0028 and 0.0020, respectively). By multivariate analysis, all three factors were identified as independent prognostic factors in postoperative GC patients (hazard ratio = 1.970, 2.021 and 2.339, respectively). In conclusion, the expression of NPM and TFF3 and, particularly, the co-expression of the two, may serve as independent prognostic factors in postoperative GC patients.

    Full Text Available Abstract Background The application and better understanding of traditional and new breast tumor biomarkers and prognostic factors are increasing due to the fact that they are able to identify individuals at high risk of breast cancer, who may benefit from preventive interventions. Also, biomarkers can make possible for physicians to design an individualized treatment for each patient. Previous studies showed that trace elements (TEs determined by X-Ray Fluorescence (XRF techniques are found in significantly higher concentrations in neoplastic breast tissues (malignant and benign when compared with normal tissues. The aim of this work was to evaluate the potential of TEs, determined by the use of the Energy Dispersive X-Ray Fluorescence (EDXRF technique, as biomarkers and prognostic factors in breast cancer. Methods By using EDXRF, we determined Ca, Fe, Cu, and Zn trace elements concentrations in 106 samples of normal and breast cancer tissues. Cut-off values for each TE were determined through Receiver Operating Characteristic (ROC analysis from the TEs distributions. These values were used to set the positive or negative expression. This expression was subsequently correlated with clinical prognostic factors through Fisher’s exact test and chi-square test. Kaplan Meier survival curves were also evaluated to assess the effect of the expression of TEs in the overall patient survival. Results Concentrations of TEs are higher in neoplastic tissues (malignant and benign when compared with normal tissues. Results from ROC analysis showed that TEs can be considered a tumor biomarker because, after establishing a cut-off value, it was possible to classify different tissues as normal or neoplastic, as well as different types of cancer. The expression of TEs was found statistically correlated with age and menstrual status. The survival curves estimated by the Kaplan-Meier method showed that patients with positive expression for Cu presented a poor

    Full Text Available CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients

    Background: The TNM classification system of tumor stage does not always reflect the actual tumor mass present at diagnosis. This study aimed at evaluating the prognostic value of volumetric data regarding survival in head and neck cancer patients being treated with either cisplatin or carboplatin administered concomitantly with radiotherapy. Patients and Methods: We retrospectively analyzed 107 patients suffering from squamous cell carcinoma of the head and neck in a Greek-German cooperational study (see Table 1). All patients were treated by radiotherapy and concomitant chemotherapy. 65 patients received chemotherapy with carboplatin and 42 with cisplatin. More than 6,200 CT scans were analyzed by digitalization of contours which subsequently led to the computation of the tumor volume (primary and macroscopic lymph node metastases). Results: Median follow-up was 43 months and median survival 30 months. Median initial tumor volume was 32.5 ml (range 2.1-220.1 ml) in the carboplatin and 44.4 ml (range 3.2-202.5 ml) in the cisplatin group (see Figure 1). After treatment, tumor volumes did not differ significantly (median of 3.1 ml [range 0.0-167.1 ml] and 3.5 ml [range 0.0-166.0 ml], respectively). 41 patients (63.1%) died in the carboplatin group and 22 patients (52.4%) in the cisplatin group (see Figure 2). Pretherapeutic tumor volume was prognostic with respect to survival while TNM classification and age were not. Pretherapeutic tumor volume was negatively and percent decrease in tumor volume positively associated with survival (see Tables 2 and 3). Conclusion: Knowledge of the initial tumor volume adds valuable information in terms of prognosis. Initial tumor volume should be included in all future clinical trials regarding head and neck cancer patients. (orig.)

    The prognosis of epithelial ovarian cancer is poor in part due to the high frequency of chemoresistance. Recent evidence points to the Toll-like receptor-4 (TLR4), and particularly its adaptor protein MyD88, as one potential mediator of this resistance. This study aims to provide further evidence that MyD88 positive cancer cells are clinically significant, stem-like and reproducibly detectable for the purposes of prognostic stratification. Expression of TLR4 and MyD88 was assessed immunohistochemically in 198 paraffin-embedded ovarian tissues and in an embryonal carcinoma model of cancer stemness. In parallel, expression of TLR4 and MyD88 mRNA and regulatory microRNAs (miR-21 and miR-146a) was assessed, as well as in a series of chemosensitive and resistant cancer cells lines. Functional analysis of the pathway was assessed in chemoresistant SKOV-3 ovarian cancer cells. TLR4 and MyD88 expression can be reproducibly assessed via immunohistochemistry using a semi-quantitative scoring system. TLR4 expression was present in all ovarian epithelium (normal and neoplastic), whereas MyD88 was restricted to neoplastic cells, independent of tumour grade and associated with reduced progression-free and overall survival, in an immunohistological specific subset of serous carcinomas, p<0.05. MiR-21 and miR-146a expression was significantly increased in MyD88 negative cancers (p<0.05), indicating their participation in regulation. Significant alterations in MyD88 mRNA expression were observed between chemosensitive and chemoresistant cells and tissue. Knockdown of TLR4 in SKOV-3 ovarian cells recovered chemosensitivity. Knockdown of MyD88 alone did not. MyD88 expression was down-regulated in differentiated embryonal carcinoma (NTera2) cells, supporting the MyD88+ cancer stem cell hypothesis. Our findings demonstrate that expression of MyD88 is associated with significantly reduced patient survival and altered microRNA levels and suggest an intact\\/functioning TLR4\\/MyD88

  6. Integral analysis of p53 and its value as prognostic factor in sporadic colon cancer

    International Nuclear Information System (INIS)

    p53 (encoded by TP53) is involved in DNA damage repair, cell cycle regulation, apoptosis, aging and cellular senescence. TP53 is mutated in around 50% of human cancers. Nevertheless, the consequences of p53 inactivation in colon cancer outcome remain unclear. Recently, a new role of p53 together with CSNK1A1 in colon cancer invasiveness has been described in mice. By combining data on different levels of p53 inactivation, we aimed to predict p53 functionality and to determine its effects on colon cancer outcome. Moreover, survival effects of CSNK1A1 together with p53 were also studied. Eighty-three formalin fixed paraffin embedded colon tumors were enriched for tumor cells using flow sorting, the extracted DNA was used in a custom SNP array to determine chr17p13-11 allelic state; p53 immunostaining, TP53 exons 5, 6, 7 and 8 mutations were determined in combination with mRNA expression analysis on frozen tissue. Patients with a predicted functional p53 had a better prognosis than patients with non functional p53 (Log Rank p=0.009). Expression of CSNK1A1 modified p53 survival effects. Patients with low CSNK1A1 expression and non-functional p53 had a very poor survival both in the univariate (Log Rank p<0.001) and in the multivariate survival analysis (HR=4.74 95% CI 1.45 – 15.3 p=0.009). The combination of mutational, genomic, protein and downstream transcriptional activity data predicted p53 functionality which is shown to have a prognostic effect on colon cancer patients. This effect was specifically modified by CSKN1A1 expression

    Highlights: • We identified that CHAF1A was up-regulated in colon tumor mucosa in TMA. • The expression pattern of CHAF1A was validated with qPCR and western-blot. • CHAF1A overexpression is an independent indicator for poor colon cancer survival. • CHAF1A facilitates cell proliferation of colon cancer both in vitro and in vivo. - Abstract: Deregulation of chromatin assembly factor 1, p150 subunit A (CHAF1A) has recently been reported to be involved in the development of some cancer types. In this study, we identified that the frequency of positive CHAF1A staining in primary tumor mucosa (45.8%, 93 of 203 samples) was significantly elevated compared to that in paired normal mucosa (18.7%, 38 of 203 samples). The increased expression was strongly associated with cancer stage, tumor invasion, and histological grade. The five-year survival rate of patients with CHAF1A-positive tumors was remarkably lower than that of patients with CHAF1A-negative tumors. Colon cancer cells with CHAF1A knockdown exhibited decreased cell growth index, reduction in colony formation ability, elevated cell apoptosis rate as well as impaired colon tumorigenicity in nude mice. Hence, CHAF1A upregulation functions as a poor prognostic indicator of colon cancer, potentially contributing to its progression by mediating cancer cell proliferation.

  9. Prognostic factors of early breast cancer treated with radiation after radical mastectomy

    International Nuclear Information System (INIS)

    Objective: To study whether post-operative radiotherapy is necessary for patients with early breast cancer after radical mastectomy. Methods: In 1998, 270 early breast cancer patients with 0 -3 pathologically confirmed positive axillary lymph nodes after radical mastectomy were retrospectively analyzed. There were 156 patients with negative lymph node and 114 with 1 -3 positive lymph nodes. The prognostic index (PI) was defined as the sum of scores of the tumor size, number of positive axillary lymph nodes, receptor status, surgical margin status, lymphatic thrombi status, pathological grading and age. The PI≥ 4 was considered as high-risk, and PI 2 = 4.40, P =0.036), respectively. The corresponding disease-free survival rate, local recurrence rate, distant metastasis rate were 71.2% and 9.6% (χ2=3.90, P=0.048), 7.7% and 16.7% (χ2=5.22, P=0.022), 12.8% and 21.1%(χ2=3.27, P=0.070), respectively. The mean dis-ease-free survival time of the two groups was 97.03±2.53 months and 87.01±3.80 months, respectively. In the high-risk group, the 10-year survival rates of patients with and without radiotherapy were 72% and 56% (χ2=4.07, P=0.044), the local recurrence rates were 5% and 24% (χ2=11.16, P=0.001), and the distant metastasis rates were 16% and 26% (χ2=2.18, P=0.140). In the low-risk group, the survival rate of patients with and without radiotherapy were 81% and 71% (χ2 =1.57, P=0.210), the local recurrence rates were both 11% (χ2=0.01, P=0.975), and the distant metastasis rates were both 13% (χ2 =0.00, P=1.000). Conclusions: Early breast cancer patients with 1 -3 positive axillary lymph nodes should receive post-operative radiotherapy after radical mastectomy. The prognostic index may decrease the chance of unnecessary radiation by distinguishing the patients under low risk of recurrence from those under high risk. (authors)

    We aim to describe trends in net survival (NS) and to assess the prognostic factors among women with de novo metastatic breast cancer (MBC) according to human epidermal growth factor receptor 2 (HER2) and hormone receptor (HR) status. Data on women suffering from de novo MBC and diagnosed from 1998 to 2009 were provided by the Côte-d'Or breast cancer registry. NS was described using the Pohar Perme estimator and prognostic factors were investigated in a generalised linear model. We identified 232 patients (mean age = 64.7). Median NS was 29.2 months, 1- and 5-year NS were 76% and 26% respectively. The survival trend in patients with HER2-positive tumours who did not receive trastuzumab was similar to that in women with triple-negative tumours. A higher relative excess risk of death by cancer was observed for high-grade tumours [RER, relative excess rates = 1.76 (95% CI, confidence intervals: 1.17-2.62) for Scarff Bloom Richardson grade 3 vs. 1 + 2], while a lower risk was observed for luminal tumours [RER = 0.49 (95% CI: 0.27-0.89)] and HER2-positive tumours treated with trastuzumab [RER = 0.28 (95% CI: 0.14-0.59)], both compared with triple-negative tumours. Surgery of the primary tumour was associated with better survival [RER = 0.43 (95% CI: 0.28-0.68)]. With half of the women dead before 29 months, stage IV breast cancer still has a bleak outlook. Progress should continue with new target therapies for both HR and HER2 receptors.

    Aim: To investigate prognostic factors and complications after radical hysterectomy followed by postoperative radiotherapy for carcinoma of the uterine cervix. Patients and Methods: One hundred twenty-eight patients with T1b-2b carcinoma of the uterine cervix following radical hysterectomy with bilateral pelvic lymphadenectomy and postoperative radiation therapy were reviewed. Pathologic and treatment variables were assessed by multivariate analysis for local recurrence, distant metastases and cause specific survival. Results: The number of positive nodes (PN) in the pelvis was the strongest predictor of pelvic recurrence and distant metastases. These 2 failure patterns independently affect the cause specific survival. The 5-year cumulative local and distant failure were PN(0): 2% and 12%, PN(1-2): 23% and 25%, PN(2<): 32% and 57%, respectively (p=0.0029 and p=0.0051). The 5-year cause specific survival rates were PN(0): 90%, PN(1-2): 59% and PN(2<): 42% (p=0.0001). The most common complication was lymphedema of the foot experienced by one-half of the patients (5-year: 42%, 10-year: 49%). Conclusion: These results suggest that patients with pathologic T1b-T2b cervix cancer with pelvic lymph node metastases are at high risk of recurrence or metastases after radical hysterectomy with pelvic lymphadenectomy and postoperative irradiation.

    were measured in 229 tumor tissue specimen from primarily operated patients with unilateral breast cancer. Non-malignant breast tissue was also dissected near the tumor and quantitative measurements were available for 211 patients. PlGF and VEGF-A protein levels in homogenized tissue lysates were...... entered in the model together. Neither PlGF nor VEGF-A expression in non-malignant tissue were predictors for RFS. Conclusion: High protein levels of PlGF and VEGF-A seem to be associated with adverse prognosis in breast cancer patients. Our results support the mutual relationship between PlGF and VEGF......-A and encourage further investigations as prognostic markers in breast cancer patients....

  14. Estimation of the prognostic value of some clinical factors and mammographical signs in breast cancer

    International Nuclear Information System (INIS)

    The aim of the work is to assess the probability of the breast cancer occurrence on the basis of analysis of the clinical and mammographical factors in women with unpalpable breast tumor. In the period from the 1st February 1995 to the 31st August 2000, 163 surgical procedures for the removal of any lesions in the breasts were conducted, after being previously marked by localized needle, in women who earlier underwent mammography exam.Following data was taken into consideration: patients age, type of the breast structure; side of the breast, where the lesion was localized in the mammography exam; localized lesions depending on the quadrant; shape of the lesion; size of the lesion in millimeters; presence and the type of microcalcifications. 1. The only one population factor, which can be distinguished as characteristic for the women suffering from the breast cancer impalpable in clinical testing, is the age of the patient, because the breast cancer in these women more frequently occurs after 53 years of age. 2. On the basis of our own material the following radiological symptoms characteristic for the breast cancer in mammography exam were stated: the breast cancer is more frequently found in the upper external quadrant; all lesions, which in mammography exam were identified as multifocal and radiologically suspected in histopathology exam turned out to be the cancer; pleomorphic microcalcifications are characteristic for the malignant lesions; external outline and the shape of the lesion are the features, which allow to differentiate malignant and benign lesions. 3. The analysis of the material indicates that the greatest probability of the breast cancer occurrence is in case of the four risk factors occurrence simultaneously, and the smallest in case of only one risk factor occurrence.

  15. Prognostic Significance of Tumor Hypoxia Inducible Factor-1α Expression for Outcome After Radiotherapy in Oropharyngeal Cancer

    International Nuclear Information System (INIS)

    Purpose: Head-and-neck squamous cell carcinoma (HNSCC) represents a heterogeneous group of patients in terms of subsite, treatment, and biology. Currently most management decisions are based on clinical parameters with little appreciation of patient differences in underlying tumor biology. We investigated the prognostic significance of clinicopathologic features and tumor hypoxia-inducible factor-1α (HIF-1α) expression in a homogeneous series of patients who underwent radiotherapy. Methods and Materials: An audit identified 133 consecutive patients with histologically proven squamous cell carcinoma of the tonsil or tongue base. All patients received primary radiotherapy between 1996 and 2001. Tumor HIF-1α expression was examined in 79 patients. Results: Features associated with poor locoregional control were low Hb level (p = 0.05) and advancing T (p = 0.008), N (p = 0.03), and disease (p = 0.008) stage. HIF-1α expression was a more significant adverse prognostic factor in the tonsil (hazard ratio [HR], 23.1; 95% confidence interval [CI]. 3.04-176.7) than the tongue-base tumor (HR, 2.86; 95% CI, 1.14-7.19) group (p = 0.03, test for interaction). High tumor HIF-1α expression was associated with low blood Hb levels (p = 0.03). In a multivariate analysis HIF-1α expression retained prognostic significance for locoregional control (HR, 7.10; 95% CI, 3.07-16.43) and cancer-specific survival (HR, 9.19; 95% CI, 3.90-21.6). Conclusions: There are significant differences in radiation therapy outcome within a homogeneous subsite of the oropharynx related to molecular marker expression. The work highlights the importance of studying homogeneous groups of patients in HNSCC, and the complex interrelationships between tumor biology and clinicopathologic factors. The establishment of tumor-type specific markers would represent a major advance in this area

    The aim of this study was to determine the impact of the main clinicopathological and biological prognostic factors of breast cancer on {sup 18}F-fluorodeoxyglucose (FDG) uptake. Only women with tumours larger than 20 mm (T2-T4) were included in order to minimize bias of partial volume effect. In this prospective study, 132 consecutive women received FDG PET/CT imaging before starting neoadjuvant chemotherapy. Maximum standardized uptake values (SUV{sub max}) were compared to tumour characteristics as assessed on core biopsy. There was no influence of T and N stage on SUV. Invasive ductal carcinoma showed higher SUV than lobular carcinoma. However, the highest uptake was found for metaplastic tumours, representing 5% of patients in this series. Several biological features usually considered as bad prognostic factors were associated with an increase in FDG uptake: the median of SUV{sub max} was 9.7 for grade 3 tumours vs 4.8 for the lower grades (p < 0.0001); negativity for oestrogen receptors (ER) was associated with higher SUV (ER+ SUV = 5.5; ER- SUV = 7.6; p = 0.003); triple-negative tumours (oestrogen and progesterone receptor negative, no overexpression of c-erbB-2) had an SUV of 9.2 vs 5.8 for all others (p = 0005); p53 mutated tumours also had significantly higher SUV (7.8 vs 5.0; p < 0.0001). Overexpression of c-erbB-2 had no effect on the SUV value. Knowledge of the factors influencing uptake is important when interpreting FDG PET/CT scans. Also, findings that FDG uptake is highest in those patients with poor prognostic features (high grade, hormone receptor negativity, triple negativity, metaplastic tumours) is helpful to determine who are the best candidates for baseline staging.

  17. Residual Tumor After Neoadjuvant Chemoradiation Outside the Radiation Therapy Target Volume: A New Prognostic Factor for Survival in Esophageal Cancer

    International Nuclear Information System (INIS)

    Purpose/Objective(s): The aim of this study was to analyze the accuracy of gross tumor volume (GTV) delineation and clinical target volume (CTV) margins for neoadjuvant chemoradiation therapy (neo-CRT) in esophageal carcinoma at pathologic examination and to determine the impact on survival. Methods and Materials: The study population consisted of 63 esophageal cancer patients treated with neo-CRT. GTV and CTV borders were demarcated in situ during surgery on the esophagus, using anatomical reference points to provide accurate information regarding tumor location at pathologic evaluation. To identify prognostic factors for disease-free survival (DFS) and overall survival (OS), a Cox regression analysis was performed. Results: After resection, macroscopic residual tumor was found outside the GTV in 7 patients (11%). Microscopic residual tumor was located outside the CTV in 9 patients (14%). The median follow-up was 15.6 months. With multivariate analysis, only microscopic tumor outside the CTV (hazard ratio [HR], 4.96; 95% confidence interval [CI], 1.03-15.36), and perineural growth (HR, 5.77; 95% CI, 1.27-26.13) were identified as independent prognostic factors for OS. The 1-year OS was 20% for patients with tumor outside the CTV and 86% for those without (P<.01). For DFS, microscopic tumor outside the CTV (HR, 5.92; 95% CI, 1.89-18.54) and ypN+ (HR, 3.36; 95% CI, 1.33-8.48) were identified as independent adverse prognostic factors. The 1-year DFS was 23% versus 77% for patients with or without tumor outside the CTV (P<.01). Conclusions: Microscopic tumor outside the CTV is associated with markedly worse OS after neo-CRT. This may either stress the importance of accurate tumor delineation or reflect aggressive tumor behavior requiring new adjuvant treatment modalities

  18. Expression of vascular endothelial growth factor (VEGF) in locally invasive prostate cancer is prognostic for radiotherapy outcome

    International Nuclear Information System (INIS)

    Purpose: Vascular endothelial growth factor (VEGF) is an important hypoxia-inducible pro-angiogenic protein that has been linked with an adverse survival outcome after radiotherapy in other cancer types: we hypothesized that this may also occur in prostate cancer. A retrospective study was, therefore, carried out to evaluate the potential of tumor VEGF expression to predict radiotherapy outcome in patients with high-risk prostate cancer. Methods and Materials: Fifty patients with locally advanced (T3 N0 M0) tumors of Gleason score ≥6, and who received radiotherapy alone as primary treatment for their disease, were studied. Vascular endothelial growth factor expression was assessed on pretreatment diagnostic tumor biopsies using a semiquantitative immunohistochemical scoring system. The results were analyzed in relation to clinicopathologic factors and patient outcome including biochemical failure and disease-specific mortality. Results: High VEGF expression was associated with a poor prognosis: in univariate log rank analysis, VEGF was the only significant prognostic factor for disease-specific survival (p = 0.035). High VEGF expression also associated with increased Gleason score (p = 0.02), but not posttreatment biochemical failure. Conclusion: High tumor expression of VEGF identified patients at high risk of failure of treatment with radiotherapy. These patients might benefit from additional treatment approaches incorporating anti-angiogenic or hypoxia-specific agents

    Full Text Available Human epididymis secretory protein 4 (HE4 is a secreted glycosylated protein encoded by the WAP four-disulfide core domain 2 (WFDC2 gene, located on a chromosome 20 segment that is frequently amplified in many cancers. This study aimed at determining serum HE4 prognostic value in non-small cell lung cancer (NSCLC, following the REMARK guidelines. Serum samples from 346 consecutive patients with histologically proven and previously untreated NSCLC and 41 patients with benign pulmonary disease were collected at the Montpellier-Nimes Academic Hospital. Work-up investigations performed to determine the disease characteristics and treatment algorithms were congruent with international guidelines. HE4 levels in serum were measured with an ELISA test (Fujirebio Diagnostics that uses two monoclonal antibodies, 2H5 and 3D8, against the C-WFDC domain of HE4. The area under the ROC curve (i.e., overall ability of HE4 to discriminate between controls and patients was 0.78 (95% confidence interval [CI], 0.738-0.821; z test P <0.0001. Serum HE4 levels were significantly higher in patients with worse performance status, advanced TNM stage and positive nodal status. In the Cox model, overall survival was shorter in patients with high pretreatment serum HE4 (above 140 pmol/L than in patients with serum H4 level ≤ 140 pmol/L [median survival: 17.7 weeks (95% CI, 11.9 to 24.9 and 46.4 weeks (95% CI, 38.6 to 56.3, respectively; hazard ratio: 1.48 (95% CI, 1.12 to 1.95 for high HE4; adjusted P = 0.0057]. High serum HE4 level at diagnosis is an independent determinant of poor prognosis in NSCLC.

Serum HE4 levels were significantly higher in patients with worse performance status, advanced TNM stage and positive nodal status. In the Cox model, overall survival was shorter in patients with high pretreatment serum HE4 (above 140 pmol/L) than in patients with serum H4 level ≤ 140 pmol/L [median survival: 17.7 weeks (95% CI, 11.9 to 24.9) and 46.4 weeks (95% CI, 38.6 to 56.3), respectively; hazard ratio: 1.48 (95% CI, 1.12 to 1.95) for high HE4; adjusted P = 0.0057]. High serum HE4 level at diagnosis is an independent determinant of poor prognosis in NSCLC.

    AIM: To compare the microRNA (miR) profiles in the primary tumor of patients with recurrent and non-recurrent gastric cancer. METHODS: The study group included 45 patients who underwent curative gastrectomies from 1995 to 2005 without adjuvant or neoadjuvant therapy and for whom adequate tumor content was available. Total RNA was extracted from formalin-fixed paraffin-embedded tumor samples, preserving the small RNA fraction. Initial profiling using miR microarrays was performed to identify potential biomarkers of recurrence after resection. The expression of the differential miRs was later verified by quantitative real-time polymerase chain reaction (qRT-PCR). Findings were compared between patients who had a recurrence within 36 mo of surgery (bad-prognosis group, n = 14, 31%) and those who did not (good-prognosis group, n = 31, 69%).RESULTS: Three miRs, miR-451, miR-199a-3p and miR-195 were found to be differentially expressed in tumors from patients with good prognosis vs patients with bad prognosis (P < 0.0002, 0.0027 and 0.0046 respectively). High expression of each miR was associated with poorer prognosis for both recurrence and survival. Using miR-451, the positive predictive value for non-recurrence was 100% (13/13). The expression of the differential miRs was verified by qRT-PCR, showing high correlation to the microarray data and similar separation into prognosis groups. CONCLUSION: This study identified three miRs, miR-451, miR-199a-3p and miR-195 to be predictive of recurrence of gastric cancer. Of these, miR-451 had the strongest prognostic impact.

    Full Text Available Abstract Background The overexpression of eukaryotic translation initiation factor 4E (eIF4E, a key regulator of protein synthesis, is involved in the malignant progression of human breast cancer. This study investigates the relationship between eIF4E and angiogenesis, as well as their prognostic impact in patients with human breast cancer. Methods Immunohistochemical staining was used to determine protein expression of eIF4E, vascular endothelial growth factor (VEGF, interleukin-8 (IL-8, and CD105 in a set of 122 formalin-fixed, paraffin-embedded primary breast cancer tissues. Expression of eIF4E in positive cells was characterized by cytoplasmic staining. Evaluation of VEGF and IL-8 in the same tissue established the angiogenic profiles, while CD105 was used as an indicator of microvessel density (MVD. Results A significant relationship was found between the level of eIF4E expression and histological grade (P = 0.016. VEGF, IL-8, and MVD were closely related to tumor grade (P = 0.003, P = 0.022, and P P = 0.007, P = 0.048, and P P = 0.007, IL-8 (P = 0.007, and MVD (P = 0.006. Patients overexpressing eIF4E had significantly worse overall (P = 0.01 and disease-free survival (P = 0.006. When eIF4E, histological grade, tumor stage, ER, PR, Her-2 status and the levels of VEGF, IL-8, MVD were included in a multivariate Cox regression analysis, eIF4E emerged as an independent prognostic factor for breast cancer (P = 0.001, along with stage (P = 0.005, node status (P = 0.046, and MVD (P = 0.004. Conclusion These results suggest that higher eIF4E expression correlates with both angiogenesis and vascular invasion of cancer cells, and could therefore serve as a useful histological predictor for less favorable outcome in breast cancer patients, as well as represent a potential therapeutic target.

  5. Prognostic factors in solitary plasmacytoma of the bone: a multicenter Rare Cancer Network study

    International Nuclear Information System (INIS)

    Solitary plasmacytoma (SP) of the bone is a rare plasma-cell neoplasm. There are no conclusive data in the literature on the optimal radiation therapy (RT) dose in SP. Therefore, in this large retrospective study, we wanted to assess the outcome, prognostic factors, and the optimal RT dose in patients with SP. Data from 206 patients with bone SP without evidence of multiple myeloma (MM) were collected. Histopathological diagnosis was obtained for all patients. The majority (n = 169) of the patients received RT alone; 32 chemotherapy and RT, and 5 surgery. Median follow-up was 54 months (7–245). Five-year overall survival, disease-free survival (DFS), and local control was 70%, 46%, and 88%; respectively. Median time to MM development was 21 months (2–135) with a 5-year probability of 51%. In multivariate analyses, favorable factors were younger age and tumor size < 5 cm for survival; younger age for DFS; anatomic localization (vertebra vs. other) for local control. Older age was the only predictor for MM. There was no dose-response relationship for doses 30 Gy or higher, even for larger tumors. Younger patients, especially those with vertebral localization have the best outcome when treated with moderate-dose RT. Progression to MM remains the main problem. Further investigation should focus on adjuvant chemotherapy and/or novel therapeutic agents

    Full Text Available Cancer in adolescents and young adults (AYAs (15-39 years is increasingly recognized as a distinct clinical and biological entity. Cancer of unknown primary (CUP, a disease traditionally presenting in older adults with a median age of 65 years, poses several challenges when diagnosed in AYA patients. This study describes clinicopathological features, outcomes and challenges in caring for AYA-CUP patients.A retrospective review of 47 AYAs diagnosed with CUP at MD Anderson Cancer Center (6/2006-6/2013 was performed. Patients with favorable CUP subsets treated as per site-specific recommendations were excluded. Demographics, imaging, pathology and treatment data was collected using a prospectively maintained CUP database. Kaplan-Meier product limit method and log-rank test were used to estimate and compare overall survival. The cox-proportional model was used for multivariate analyses.Median age was 35 years (range 19-39. All patients underwent comprehensive workup. Adenocarcinoma was the predominant histology (70%. A median of 9 immunostains (range 2-29 were performed. The most common putative primary was biliary tract based on clinicopathological parameters as well as gene profiling. Patients presented with a median of 2 metastatic sites [lymph node (60%, lung (47%, liver (38% and bone (34%]. Most commonly used systemic chemotherapies included gemcitabine, fluorouracil, taxanes and platinum agents. Median overall survival for the entire cohort was 10.0 (95% confidence interval (CI: 6.7-15.4 months. On multivariate analyses, elevated lactate dehydrogenase (Hazard ratio (HR 3.66; 95%CI 1.52-8.82; P = 0.004, ≥3 metastatic sites (HR 5.34; 95%CI 1.19-23.9; P = 0.029, and tissue of origin not tested (HR 3.4; 95%CI 1.44-8.06; P = 0.005 were associated with poor overall survival. Culine's CUP prognostic model (lactate dehydrogenase, performance status, liver metastases was validated in this cohort (median overall survival: good-risk 25.2 months vs

    Soft-tissue sarcomas remain aggressive tumors that result in death in greater than a third of patients due to either loco-regional recurrence or distant metastasis. Surgical resection remains the main choice of treatment for soft tissue sarcomas with pre- and/or post-operational radiation and neoadjuvant chemotherapy employed in more advanced stage disease. However, in recent decades, there has been little progress in the average five-year survival for the majority of patients with high-grade soft tissue sarcomas, highlighting the need for improved targeted therapeutic agents. Clinical and preclinical studies demonstrate that tumor hypoxia and up-regulation of hypoxia-inducible factors (HIFs) is associated with decreased survival, increased metastasis, and resistance to therapy in soft tissue sarcomas. HIF-mediated gene expression regulates many critical aspects of tumor biology, including cell survival, metabolic programming, angiogenesis, metastasis, and therapy resistance. In this review, we discuss HIFs and HIF-mediated genes as potential prognostic markers and therapeutic targets in sarcomas. Many pharmacological agents targeting hypoxia-related pathways are in development that may hold therapeutic potential for treating both primary and metastatic sarcomas that demonstrate increased HIF expression.

  8. MiR-378 is an independent prognostic factor and inhibits cell growth and invasion in colorectal cancer

    International Nuclear Information System (INIS)

    MicroRNAs(miRNAs) are small non-coding RNAs that participate in a variety of biologic processes, and dysregulation of miRNA is always associated with cancer development and progression. Aberrant expression of miR-378 has been found in some types of cancer. However, effects and potential mechanisms of miR-378 in colorectal cancer (CRC) have not been explored. Quantitative RT-PCR was performed to evaluate miR-378 levels in CRC cell lines and 84 pairs of CRC cancer and normal adjacent mucosa. Kaplan–Meier and Cox proportional regression analyses were utilized to determine the association of miR-378 expression with survival of patients. MTT and invasion assays were used to determine the role of miR-378 in regulation of CRC cancer cell growth and invasion, respectively. Tumor growth was assessed by subcutaneous inoculation of cells into BALB/c nude mice. Luciferase assay was performed to assess miR-378 binding to vimentin gene. In this study, we confirmed that miR-378 significantly down-regulated in CRC cancer tissues and cell lines. Moreover, patients with low miR-378 expression had significantly poorer overall survival, and miR-378 expression was an independent prognostic factor in CRC. Over-expression of miR-378 inhibited SW620 cell growth and invasion, and resulted in down-regulation of vimentin expression. However, miR-378 knock-down promoted these processes and enhanced the expression of vimentin. In addition, we further identified vimentin as the functional downstream target of miR-378 by directly targeting the 3′-UTR of vimentin. In conclusion, miR-378 may function as a tumor suppressor and plays an important role in inhibiting tumor growth and invasion. Our present results implicate the potential effects of miR-378 on prognosis and treatment of CRC cancer

    For locally advanced cervical cancer (LACC), hypoxia is a characteristic property. This study aimed to investigate whether baseline lactic dehydrogenase (LDH) level, which is a marker of hypoxia, had clinical value in determining neoadjuvant chemotherapy (NACT) response and prognosis for LACC patients. The study cohort included 418 patients with a median follow-up of 37.5 months. Cox proportional hazards models were used to assess the prognostic value of baseline LDH levels. Multivariate logistic regression analysis was performed to identify independent predictors of complete response after NACT. Backward stepwise selection with the Akaike information criterion was used to identify factors that could be entered into the multivariate regression model. Compared with patients with LDH levels NACT (adjusted odds ratio [OR], 0.29; 95% CI, 0.15-0.58; P NACT. PMID:27350066

    Background: With the continuing increase in the use of definitive stereotactic radiosurgery (SRS) for patients with limited brain metastases (BM), clinicians need more specific prognostic tools. We investigated clinical predictors of outcomes in patients with limited breast cancer BM treated with SRS alone. Methods and Materials: We identified 136 patients with breast cancer and 1-3 BM who underwent definitive SRS for 186 BM between 2000 and 2012. The Kaplan-Meier method was used to assess overall survival (OS), regional failure (RF), and local failure (LF). Associations between clinical factors and outcomes were tested using Cox regression. A point scoring system was used to stratify patients based on OS, and the predictive power was tested with concordance probability estimate (CPE). Results: The median OS was 17.6 months. The 12-month RF and LF rates were 45% and 10%, respectively. On multivariate analysis, >1 lesion (hazard ratio [HR] = 1.6, P=.02), triple-negative (TN) disease (HR=2.0, P=.006), and active extracranial disease (ED) (HR=2.7, P<.0001) were significantly associated with worse OS. The point score system was defined using proportional simplification of the multivariate Cox proportional hazards regression function. The median OS for patients with 3.0-4.0 points (n=37), 4.5-5.5 points (n=28), 6.0-6.5 points (n=37), and 8-8.5 points (n=34) were 9.2, 15.6, 25.1, and 45.1 months, respectively (P<.0001, CPE = 0.72). Active ED (HR=2.4, P=.0007) was significantly associated with RF. Higher risk for LF was significantly associated with larger BM size (HR=3.1, P=.0001). Conclusion: Patients with >1 BM, active ED, and TN had the highest risk of death after SRS. Active ED is an important prognostic factor for OS and intracranial control.

  12. Prognostic factors, patterns of recurrence and toxicity for patients with esophageal cancer undergoing definitive radiotherapy or chemo-radiotherapy

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the effectiveness and tolerability of definitive chemo-radiation or radiotherapy alone in patients with esophageal cancer. We retrospectively analyzed the medical records of n = 238 patients with squamous cell carcinoma or adenocarcinoma of the esophagus treated with definitive radiotherapy with or without concomitant chemotherapy at our institution between 2000 and 2012. Patients of all stages were included to represent actual clinical routine. We performed univariate and multivariate analysis to identify prognostic factors for overall survival (OS) and progression-free survival (PFS). Moreover, treatment-related toxicity and patterns of recurrence were assessed. Patients received either chemo-radiation (64%), radiotherapy plus cetuximab (10%) or radiotherapy alone (26%). In 69%, a boost was applied, resulting in a median cumulative dose of 55.8 Gy; the remaining 31% received a median total dose of 50 Gy. For the entire cohort, the median OS and PFS were 15.0 and 11.0 months, respectively. In multivariate analysis, important prognostic factors for OS and PFS were T stage (OS: P = 0.005; PFS: P = 0.006), M stage (OS: P = 0.015; PFS: P = 0.003), concomitant chemotherapy (P < 0.001) and radiation doses of >55 Gy (OS: P = 0.019; PFS: P = 0.022). Recurrences occurred predominantly as local in-field relapse or distant metastases. Toxicity was dominated by nutritional impairment (12.6% with G3/4 dysphagia) and chemo-associated side effects. Definitive chemo-radiation in patients with esophageal cancer results in survival rates comparable with surgical treatment approaches. However, local and distant recurrence considerably restrict prognosis. Further advances in radio-oncological treatment strategies are necessary for improving outcome. (author)

    Full Text Available Abstract Background The aim of this population-based study was to assess independent prognostic factors in ovarian cancer using relative survival (RS and to investigate changes in RS rates from 1982 to 2005. Methods Data on 748 patients with ovarian cancer were provided by the Côte d'Or gynaecologic cancer registry. The RS was estimated using a generalized linear model with a Poisson error structure. Relative survival and its 95% confidence interval (CI were described at the following specific time points 1, 3 and 5 years. The effect of prognostic factors on survival was assessed with multivariate analyses of RS. Results The median follow-up was 12 years. The RS rates at 1, 3 and 5 years were 81%, 55% and 44%, respectively. As compared with the period 1982-1989, an improvement in survival was found for the period 1998-2005: HR = 0.52[0.40-0.67]. Women who lived in urban areas had better RS: HR = 0.82[0.67-0.99]. Patients with epithelial types of ovarian cancer other than mucinous or endometrioid cancer had worse RS than those with serous histology. Age ≥ 70 years was associated with lower survival. Conclusions Period of diagnosis, stage at diagnosis, histology, place of residence and age were independent prognostic factors for survival in ovarian cancer. An improvement in the survival rate was observed after 1998 but a significant improvement was limited to advanced stage cancers.

    FOLFIRINOX is a standard first-line treatment for advanced pancreatic cancer (aPC). The Gruppo Oncologico Nord Ovest (GONO) FOLFOXIRI regimen demonstrated efficacy in metastatic colorectal cancer. We aimed to evaluate activity and tolerability of FOLFOXIRI regimen in patients with aPC and to explore putative prognostic factors. One hundred thirty-seven consecutive aPC patients were treated with FOLFOXIRI in our institution between 2008 and 2014. Clinical, laboratory and pathological data were collected and their association with activity, progression free survival (PFS) and overall survival (OS) was investigated. After a median follow up of 30 months, median PFS and OS were 8.0 months (95% CI 6.19-9.81) and 12 months (95% CI 9.75-14.25), respectively. Response rate was 38.6%, while disease-control rate 72.2%. At multivariate analysis liver metastases (p = 0.019; Hazard Ratio, HR, 0.59, 95% Confidence Interval, CI, 0.380.96), Eastern Cooperative Oncology Group (ECOG) performance status (PS) 1 (p = 0.001; HR 2.26, 95%CI 1.42-3.59) and neutrophil-lymphocyte ratio (NLR)> 4 (p= 0.002; HR: 2.42; 95% CI 1.38-4.25) were associated with poorer OS. We categorized 119 pts with complete available data as good-risk (0 factors, 38 pts), intermediate-risk (1 factor, 49 pts) and poor-risk (≥2 factors, 32 pts). Median OS for these three groups were 17.6, 11.1 and 7.4 months, respectively (p factors: our analysis revealed ECOG PS, liver metastases and NLR as the most important predictors of survival. These factors could be helpful for treatment decision and clinical trial design. PMID:27038273

    AIM: To determine the expression of miR-422a in colorectal cancer (CRC) tissues and to further explore the prognostic value and function of miR-422a in CRC carcinogenesis. METHODS: miR-422a expression was analyzed in 102 CRC tissues and paired normal mucosa adjacent to carcinoma by quantitative real-time PCR. The relationship of miR-422a expression with clinicopathological parameters was also analyzed. Kaplan-Meier analysis and Cox multivariate analysis were performed to estimate the potential role of miR-422a. Cell proliferation, migration, and invasion were used for in vitro functional analysis of miR-422a. RESULTS: The levels of miR-422a were dramatically reduced in CRC tissues compared with normal mucosa (P < 0.05), and significantly correlated with local invasion (P = 0.004) and lymph node metastasis (P < 0.001). Kaplan-Meier survival and Cox regression multivariate analyses revealed that miR-422a expression (HR = 0.568, P = 0.015) and clinical TNM stage (HR = 2.942, P = 0.003) were independent prognostic factors for overall survival in CRC patients. Furthermore, in vitro experiments showed that overexpression of miR-422a inhibited the proliferation, migration, and invasion of SW480 and HT-29 cells. CONCLUSION: Down-regulation of miR-422a may serve as an independent prognosis factor in CRC. MiR-422a functions as a tumor suppressor and regulates progression of CRC. PMID:27350737

    BACKGROUND: Recent studies have shown the clinical significance of epidermal growth factor-like domain 7 (EGFL7) in a variety of cancers. However, the relationship between EGFL7 and the prognosis of pancreatic cancer (PC) remains unclear. The present study was undertaken to investigate the role of EGFL7 in the prognosis of PC. METHODS: The expression of EGFL7 in nine PC cell lines was first determined by Western blotting analysis. Tissue microarray-based immunohistochemical staining was performed in paired formalin-fixed paraffin-embedded tumor and non-tumor samples from 83 patients with PC. Finally, correlations between EGFL7 expression and clinicopathological variables as well as overall survival were evaluated. RESULTS: EGFL7 was widely expressed in all PC cell lines tested. EGFL7 expression in tumor tissues was significantly higher than that in non-tumor tissues (P=0.040). In addition, univariate analysis revealed that high EGFL7 expression in tumor tissues was significantly associated with poor overall survival, accompanied by several conventional clinicopathological variables, such as gender, histological grade and lymph node metastasis. In a multivariate Cox regression test, EGFL7 expression was identified as an independent marker for longterm outcome of PC. CONCLUSION: Our data showed that EGFL7 is extensively expressed in PC and that EGFL7 is associated with poor prognosis.

    Full Text Available Introduction: The present study identifies the prognostic factors influencing oral cancers in a large cohort of patients treated at a single institute. Materials and Methods: This is an audit of 1180 patients treated from 1990 to 2004 in the service setting with prospective data collection. Patients were treated with radical radiotherapy or were planned for surgery and post operative radiotherapy (PORT. None of the patients received postoperative concurrent chemoradiation. For analysis, patients were divided into Group 1 and Group 2 based on the oral cavity subsite. Results: Of the entire cohort, 810 patients had tumors of the Gingivo-alveolo-buccal complex, lip and hard palate (Group 1 and 370 patients had primaries in tongue and floor of mouth (Group 2. Three year locoregional control for the entire cohort was 58%. The three year local control (LC, locoregional control (LRC and disease free survival (DFS for PORT group were 74%, 65% and 60%, respectively, with pathological nodal status, perinodal extension and cut margin status showing statistical significance (P <0.001. In the definitive radiotherapy group, the three year LC, LRC and DFS were 34%, 31% and 30%, respectively, with age, T stage, nodal status and stage being significant. Group 1 patients showed significantly better LC, LRC and DFS than Group 2 patients for the entire cohort. Conclusion: The results indicate superior outcomes with PORT particularly in advanced stages of oral cancer and inferior outcomes in tongue and floor of mouth subsites. There is scope for improving outcomes by adopting treatment intensification strategies.

    International Nuclear Information System (INIS)

    Purpose: Potential risk factors including DNA flow cytometric-derived parameters predicting loco-regional recurrence (LRR) in early breast cancer were investigated.Materials and methods: This study included 608 patients treated by modified radical mastectomy between 1982 and 1987. Recommendations regarding local treatment as well as adjuvant systemic therapy did not change during this period. Patients treated by adjuvant chemotherapy were randomized to receive additional medroxyprogesterone acetate (MPA) treatment. Only 59 (10%) patients received postoperative irradiation (XRT) to the chest wall and/or axillary lymph nodes; another 121 (20%) patients received XRT to the internal mammary nodes because of centromedially located tumours.Results: Patients were followed for a median period of 7.5 years. The event-free survival at 10 years was 50%. The cumulative incidence rate of LRR at 10 years was 18% (n=93), either with (n=30) or without (n=63) concurrent distant metastases. The chest wall, regional lymph nodes or both were involved in 41 (44%), 38 (41%) and 12 (13%) patients, respectively. Multivariate analysis according to the Cox model revealed two factors associated with LRR, i.e. pT (P<0.05) and nodal status (P<0.0510%) and low risk (<10%) group for LRR could be identified.Conclusions: Results indicate that T-stage and nodal status, combined with ECE, may help to identify patients at risk for loco-regional recurrence, whereas DNA flow cytometry does not.

    Full Text Available Background. The design and introduction of novel medicaments into clinical practice has confirmed that it is necessary to search for new prognostic factors to re-evaluate the clinical and biological properties of a tumor and to identify a subgroup of patients who will benefit from drug treatment. An individual approach and personalization of performed therapy will be able to substantially enhance its efficiency.Subjects and methods. Thirty-four oncology and urology research and health care institutions from 8 federal districts of the Russian Federation took part in the investigation. It enrolled 145 metastatic renal-cell cancer patients who had received targeted therapy with a combination of bevacizumab and interferon-α (IFN-α, in whom an objective response (complete or partial regression or stabilization of tumor foci was recorded during at least 3-month treatment. The main task of the investigation was to estimate the clinical importance of chosen criteria (an interval from the diagnosis to start of treatment; physical activity according to the Karnofsky scale; a history of nephrectomy; the site and number of metastatic foci; the levels of hemoglobin, neutrophils, platelets, calcium, and alkaline phosphatase as predictors for the efficiency of bevacizumab therapy.Results. The median follow-up was 9 months (interquartile range (IQR 6–13 months. The duration of treatment varied between 3 to 22 months; the median was 9 months (IQR 6–13 months. Patients with 3-month progression were excluded from the investigation. A complete and partial responses were recorded in 5 (3.4 % and 19 (13.1 % patients, respectively; the tumor process was stabilized in 118 (81.4 % patients. The median duration of response to therapy with a combination of bevacizumab and IFN-α was 7 months (IQR 5–10 months. The progression-free survival was significantly influenced by prognostic factors, such as hemoglobin and neutrophil levels, age, and time from the diagnosis

  6. Treatment results and prognostic factors of early breast cancer treated with a breast conserving operation and radiotherapy

    International Nuclear Information System (INIS)

    The purpose of this study was to analyze the prognostic factors affecting local control and survival rates for patients with early breast cancer who received breast conserving treatment (BCT) and to find out the optimal treatment according to their risk factors. From October 1994 to December 2001, 605 patients with 611 stage I and II breast cancers received BCT, and the results were analyzed retrospectively. BCT consists of breast conserving surgery and whole breast irradiation. All the patients underwent lumpectomy or quad-rantectomy. Axillary lymph node dissection or sentinel lymph node biopsy was performed in 608 cases (99.5%). The radiation dose to the whole breast was 50.4 Gy over 5 weeks with a 1.8 Gy daily fraction and with boost doses of 9-14.4 Gy administered to the tumor bed. Adjuvant chemotherapy was performed in most of the patients with axillary lymph node metastasis or tumors larger than 1 cm. The median follow-up period was 47 months. Local relapse, regional relapse and distant metastasis occurred in 15 (2.5%), 16 (2.6%) and 43 patients (7.1%), respectively. The 5-year overall survival, local-relapse-free survival, distant-metastasis-free survival and disease-free survival rates were 95.3%, 97.2%, 91.3% and 88.5%, respectively. On multivariate analysis, age (P=0.02), number of involved axillary lymph nodes (P=0.01) and nuclear grade (P=0.01) affected the local-relapse-free survival. The factors associated with disease-free survival were the T stage (P=0.05), number of involved axillary lymph nodes (P=0.01) and nuclear grade (P=0.001). Overall survival was associated with the T stage (P=0.02), number of involved axillary lymph nodes (P=0.01) and c-erb B2 overexpression (P=0.05). Patients with more than two factors among age≤35 years, positive lymph node metastasis and high nuclear grade showed a poor 5-year local-relapse-free survival rate compared with others (P=0.001). Also, patients with more than two factors among tumor size >1 cm, positive

    2011-03-09

    Abstract Background Thromboxane synthase (TXS) metabolises prostaglandin H2 into thromboxanes, which are biologically active on cancer cells. TXS over-expression has been reported in a range of cancers, and associated with a poor prognosis. TXS inhibition induces cell death in-vitro, providing a rationale for therapeutic intervention. We aimed to determine the expression profile of TXS in NSCLC and if it is prognostic and\\/or a survival factor in the disease. Methods TXS expression was examined in human NSCLC and matched controls by western analysis and IHC. TXS metabolite (TXB2) levels were measured by EIA. A 204-patient NSCLC TMA was stained for COX-2 and downstream TXS expression. TXS tissue expression was correlated with clinical parameters, including overall survival. Cell proliferation\\/survival and invasion was examined in NSCLC cells following both selective TXS inhibition and stable TXS over-expression. Results TXS was over-expressed in human NSCLC samples, relative to matched normal controls. TXS and TXB2 levels were increased in protein (p < 0.05) and plasma (p < 0.01) NSCLC samples respectively. TXS tissue expression was higher in adenocarcinoma (p < 0.001) and female patients (p < 0.05). No significant correlation with patient survival was observed. Selective TXS inhibition significantly reduced tumour cell growth and increased apoptosis, while TXS over-expression stimulated cell proliferation and invasiveness, and was protective against apoptosis. Conclusion TXS is over-expressed in NSCLC, particularly in the adenocarcinoma subtype. Inhibition of this enzyme inhibits proliferation and induces apoptosis. Targeting thromboxane synthase alone, or in combination with conventional chemotherapy is a potential therapeutic strategy for NSCLC.

To evaluate p53, HoxD10, and E-cadherin status in breast cancer and to correlate with histological grade and other prognostic factors. Material and Methods. The study was conducted in 60 cases of invasive ductal carcinoma NOS with 20 cases belonging to each grade and evaluation of p53 was done by IHC and that of HoxD10 and E Cadherin status by PCR and correlation was done with histological grade and other prognostic factors. Result. p53 expression was seen in 71.67% (43/60 of the tumors. HoxD10 gene was downregulated in 46.67% (28/60 of the tumors. p53 overexpression and lower HoxD10 mRNA levels showed statistically significant association higher histological grade of the tumor (P<0.05. CDH1 gene mutation was seen in 60% (15/25 of the tumors. No significant association was found between p53 expression, HoxD10 gene, CDH1 gene mutation, and other prognostic factors. Conclusion. p53 over expression and lower HoxD10 mRNA levels were found to be significantly associated with higher grade tumours. This suggests that p53 and HoxD10 gene play an important tumor suppressor role and the loss of which results in breast cancer progression.

    2010-07-01

    Full Text Available Abstract Background Hypoxia-inducible factor 1 (HIF-1 is a master transcriptional regulator of genes regulating oxygen homeostasis. The HIF-1 protein is composed of two HIF-1α and HIF-1β/aryl hydrocarbon receptor nuclear translocator (ARNT subunits. The prognostic relevance of HIF-1α protein overexpression has been shown in breast cancer. The impact of HIF-1α alternative splice variant expression on breast cancer prognosis in terms of metastasis risk is not well known. Methods Using real-time quantitative reverse transcription PCR assays, we measured mRNA concentrations of total HIF-1α and 4 variants in breast tissue specimens in a series of 29 normal tissues or benign lesions (normal/benign and 53 primary carcinomas. In breast cancers HIF-1α splice variant levels were compared to clinicopathological parameters including tumour microvessel density and metastasis-free survival. Results HIF-1α isoforms containing a three base pairs TAG insertion between exon 1 and exon 2 (designated HIF-1αTAG and HIF-1α736 mRNAs were found expressed at higher levels in oestrogen receptor (OR-negative carcinomas compared to normal/benign tissues (P = 0.009 and P = 0.004 respectively. In breast carcinoma specimens, lymph node status was significantly associated with HIF-1αTAG mRNA levels (P = 0.037. Significant statistical association was found between tumour grade and HIF-1αTAG (P = 0.048, and total HIF-1α (P = 0.048 mRNA levels. HIF-1αTAG mRNA levels were also inversely correlated with both oestrogen and progesterone receptor status (P = 0.005 and P = 0.033 respectively. Univariate analysis showed that high HIF-1αTAG mRNA levels correlated with shortened metastasis free survival (P = 0.01. Conclusions Our results show for the first time that mRNA expression of a HIF-1αTAG splice variant reflects a stage of breast cancer progression and is associated with a worse prognosis.

    The purpose of the present study was to assess prognostic factor for metachronous contralateral recurrence of breast cancer (CBC). Two factors were of particular interest, namely estrogen (ER) and progesterone (PgR) receptors assayed with the biochemical method in primary tumor tissue. Information was obtained from a prospective clinical database for 1763 axillary node-negative women who had received curative surgery, mostly of the conservative type, and followed-up for a median of 82 months. The analysis was performed based on both a standard (linear) Cox model and an artificial neural network (ANN) extension of this model proposed by Faraggi and Simon. Furthermore, to assess the prognostic importance of the factors considered, model predictive ability was computed. In agreement with already published studies, the results of our analysis confirmed the prognostic role of age at surgery, histology, and primary tumor site, in that young patients (< or = 45 years) with tumors of lobular histology or located at inner/central mammary quadrants were at greater risk of developing CBC. ER and PgR were also shown to have a prognostic role. Their effect, however, was not simple in relation to the presence of interactions between ER and age, and between PgR and histology. In fact, ER appeared to play a protective role in young patients, whereas the opposite was true in older women. Higher levels of PgR implied a greater hazard of CBC occurrence in infiltrating duct carcinoma or tumors with an associated extensive intraductal component, and a lower hazard in infiltrating lobular carcinoma or other histotypes. In spite of the above findings, the predictive value of both the standard and ANN Cox models was relatively low, thus suggesting an intrinsic limitation of the prognostic variables considered, rather than their suboptimal modeling. Research for better prognostic variables should therefore continue.

The aim of the study was to evaluate EGFR expression in colorectal cancer (CRC specimens and to determine whether EGFR expression correlates with clinicopathological data and overall survival.Patients and methods: Tissue specimens from 181 consecutive CRC patients treated at the Military Institute of Medicine in 2006–2010 were collected and examined for EGFR expression, by immunohistochemistry staining. The staining intensity and percentage of cells with membranous EGFR expression were scored and then grouped according to the parameters of the Allred Scoring system. Cutoff values were subjected to further statistical analysis. Univariate tests and a multivariate Cox proportional hazards model were used in data analysis.Results: EGFR was overexpressed in 96 of 181 CRC specimens (53%. EGFR expression was not correlated with other clinicopathological variables. On univariate analysis, overexpression of EGFR, determined by PS (percentage score (>3 and total score (sum of PS and intensity score (>4, was associated with poor overall survival. On multivariate analysis, EGFR overexpression (PS > 3 was an independent adverse prognostic factor (hazard ratio [HR] 1.62; 95% confidence interval [CI]: 1.03–2.53.

    Full Text Available For colorectal cancer patients, long-term survival is achievable only after complete resection of the disease. However, the decision to embark on a multi-visceral resection must be made after weighing the risks against the potential benefits. We retrospectively analyzed the demographics, tumor parameters, perioperative results, oncological outcomes and survival details of 35 patients who underwent multivisceral resection for colorectal carcinoma between 1996 and 2013. 'Multivisceral resection' was defined as the resection of at least one other organ in addition to cancer affected the colon. There were 19 males and 16 females who had a mean age of 52.7 ± 13.6 years. The most common primary site of the tumor was the rectum, followed by the sigmoid, the left, and the right colon. Most frequently resected additional organ was the pancreas followed by the uterus, small bowel, urinary bladder, ureter, vagina, spleen, duodenum, ovary, and liver. Postoperative histopathological examination confirmed tumor infiltration in the adjacent organs in 48.5%. The postoperative complication was developed in 21 (60% patients. There was no surgery-related mortality. Ten patients had evidence of recurrence at last follow-up in June 2014. The 5-year survival rate was of 73.1% according to Kaplan-Meier survival analysis. Multivisceral resection for colorectal cancer is associated with a high morbidity rate, but the long-term survival is good.

    Full Text Available Beckground/Aim. Neuroendrocine lung tumors are histologically heterogenous group of cancers with different clinical progression. In non-small cell lung cancer (NSCLC neuroendocrine differentiation exists in 10-30% of patients. The aim of this study was to determine the frequency and influence of neuroendocrine differentiation on survival of treated patients with advanced non-small cell lung cancer (NSCLC. Methods. A clinical trial included 158 patients (74% males and 26% females, with the diagnosis of NSCLC, determined by histological verification. The patients were treated by combined chemo - and X-ray therapy in stage III (without pleural effusion or chemotherapy only in stage III (with pleural effusion and stage IV. Chemotherapy was conducted until progression of the disease, but no more than six cycles. When the progression had been noted in stage III (without pleural effusion, the treatment was continued with X-ray therapy. Neuron specific enolase, chromogranin A, as well as synapthophysin expression in tissue examples were determined by immunohistochemical analysis with monoclonal mouse anti-human-bodies. Survival was assessed within a year and two years follow-up examination. Results. A total of 53 patients (34% had NSCLC with neuroendocrine differentiation, confirmed rather in large cell lung cancer and lung adenocarcinoma (66.7% and 40%, respectively. Neuron specific enolase, chromogranin A and synapthophysin expression was noted in 45 (28.5%, 34 (21.5% and 33 (20.1% patients, respectively. The one year and two years follow-up survival periods were confirmed in 39% and 17% of patients respectively. The median survival time in the patients with the neuroendocrine expression as compared to those without the expression was 15.6 vs 10.8 months; one year survival time with the expression compared to those without the expression achieved in 62% vs 27% of the patients, (p < 0.001; a two - year survival time noted in 30% of the patients (p = 0

    Outcome of consecutive patients with locally advanced non-small cell lung cancer and histopathologically proven mediastional lymph node metastases treated with induction chemotherapy, neoadjuvant radiochemotherapy and thoracotomy at the West German Cancer Center between 08/2000 and 06/2012 was analysed. A clinico-pathological prognostic model for survival was built including partial or complete response according to computed tomography imaging (CT) as clinical parameters as well as pathologic complete remission (pCR) and mediastinal nodal clearance (MNC) as histopathologic factors. Proportional hazard analysis (PHA) and recursive partitioning analysis (RPA) were used to identify prognostic factors for survival. Long-term survival was defined as survival ≥ 36 months. A total of 157 patients were treated, median follow-up was 97 months. Among these patients, pCR and MNC were observed in 41 and 85 patients, respectively. Overall survival was 56 ± 4% and 36 ± 4% at 24 and 60 months, respectively. Sensitivities of pCR and MNC to detect long-term survivors were 38% and 61%, specificities were 84% and 52%, respectively. Multivariable survival analysis revealed pCR, cN3 category, and gender, as prognostic factors at a level of α < 0.05. Considering only preoperative available parameters, CT response became significant. Classifying patients with a predicted hazard above the median as high risk group and the remaining as low risk patients yielded better separation of the survival curves by the inclusion of histopathologic factors than by preoperative factors alone (p < 0.0001, log rank test). Using RPA, pCR was identified as the top prognostic factor above clinical factors (p = 0.0006). No long term survivors were observed in patients with cT3-4 cN3 tumors without pCR. pCR is the dominant histopathologic response parameter and improves prognostic classifiers, based on clinical parameters. The validated prognostic model can be used to estimate individual prognosis and

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to assess the outcome in patients with cerebellar glioblastoma (GBM) treated in 15 institutions of the Rare Cancer Network. Methods and Materials: Data from a series of 45 adult patients with cerebellar GBM were collected in a retrospective multicenter study. Median age was 50.3 years. Brainstem invasion was observed in 9 (20%) patients. Radiotherapy (RT) was administered to 36 patients (with concomitant chemotherapy, 7 patients). Adjuvant chemotherapy after RT was administered in 8 patients. Median RT dose was 59.4 Gy. Median follow-up was 7.2 months (range, 3.4-39.0). Results: The 1-year and 2-year actuarial overall survival rate was 37.8% and 14.7%, respectively, and was significantly influenced by salvage treatment (p = 0.048), tumor volume (p = 0.044), extent of neurosurgical resection (p = 0.019), brainstem invasion (p = 0.0013), additional treatment after surgery (p < 0.001), and completion of the initial treatment (p < 0.001) on univariate analysis. All patients experienced local progression: 8 and 22 had progression with and without a distant failure, respectively. The 1- and 2-year actuarial progression free survival was 25% and 10.7%, respectively, and was significantly influenced by brainstem invasion (p = 0.002), additional treatment after surgery (p = 0.0016), and completion of the initial treatment (p < 0.001). On multivariate analysis, survival was negatively influenced by the extent of surgery (p = 0.03) and brainstem invasion (p = 0.02). Conclusions: In this multicenter retrospective study, the observed pattern of failure was local in all cases, but approximately 1 patient of 4 presented with an extracerebellar component. Brainstem invasion was observed in a substantial number of patients and was an adverse prognostic factor

    2007-01-01

    AIM: To determine whether the telomerase activity is related to the Microsatellite instability (MSI) genetic pathway and whether it means a difference in the survival.METHODS: The population consisted of 97 colorectal cancer patients. MSI determination was performed in accordance with the NCI criteria using PCR and Genescan. Telomerase activity was determined by the TRAP-assay, an ELISA procedure based on the amplification of telomeric repeat sequences.RESULTS: 6.2% showed high MSI (MSI-H), 10.3% showed low MSI (MSI-L) and 83.5% did not show this alteration (MSS). Positive telomerase activity was detected in 92.8% of the patients. 83.3% of MSI-H tumors showed positive telomerase against 93.8% of MSS tumors. In the overall survival analysis the absence of telomerase activity conferred a better prognosis.CONCLUSION: Previous works have shown that tumors which develop via the MSI pathway present a better prognosis. No link between telomerase activity and MSI status is observed, although sample sizes are small.Patients with telomerase negative tumors had better overall survival than patients with telomerase positive tumors.

    Full Text Available Serine protease inhibitors (SERPINs appear to be ubiquitously expressed in a variety of species and play important roles in pivotal physiological processes such as angiogenesis, immune responses, blood coagulation and fibronolysis. Of these, squamous cell carcinoma antigen 1 (SCCA1, also known as a SERPINB3, was first identified in squamous cell carcinoma tissue from the cervix of women. However, there is little known about the SERPINB3 expression in human epithelial ovarian cancer (EOC. Therefore, in the present study, we investigated the functional role of SERPINB3 gene in human EOC using chickens, the most relevant animal model. In 136 chickens, EOC was found in 10 (7.4%. SERPINB3 mRNA was induced in cancerous, but not normal ovaries of chickens (P<0.01, and it was abundant only in the glandular epithelium of cancerous ovaries of chickens. Further, several microRNAs, specifically miR-101, miR-1668 and miR-1681 were discovered to influence SERPINB3 expression via its 3'-UTR which suggests that post-transcriptional regulation influences SERPINB3 expression in chickens. SERPINB3 protein was localized predominantly to the glandular epithelium in cancerous ovaries of chickens, and it was abundant in the nucleus of both chicken and human ovarian cancer cell lines. In 109 human patients with EOC, 15 (13.8%, 66 (60.6% and 28 (25.7% patients showed weak, moderate and strong expression of SERPINB3 protein, respectively. Strong expression of SERPINB3 protein was a prognostic factor for platinum resistance (adjusted OR; odds ratio, 5.94; 95% Confidence Limits, 1.21-29.15, and for poor progression-free survival (PFS; adjusted HR; hazard ratio, 2.07; 95% CI; confidence interval, 1.03-4.41. Therefore, SERPINB3 may play an important role in ovarian carcinogenesis and be a novel biomarker for predicting platinum resistance and a poor prognosis for survival in patients with EOC.

    In the recent years several studies have shown that about 30% of cases with axillary node-nagative breast cancer suffer relapse of the disease. Our attempt was made to evaluate the most significant prognostic factors to predict this high risk group which may be benefited from adjuvant treatment. For this purpose, we selected 9 patients out of 80 cases of node-negative breast cancer who had been followed up at least for 5 years and had the recurrence of the disease. For comparison, 16 patients from the same group who did not have relapse were selected on a random basis. Histology, receptor status, AgNOR, DNA flow cytometry and various immunohistochemical parameters were compared between the groups with recurrence and that without recurrence. On univariate analysis, tumor size, immunohistochemical expressions of PCNA, MIB-1, c-erbB-2 and S-phase fraction were significantly different between the above two groups. By multivariate analysis, immunohistochemical c-erbB-2 expression (more than 50% of cancer cells) was an independent parameter. As a summary from our studies, c-erbB-2 immunohistochemical staining on paraffin sections might be the best independent prognostic factor in axillary node-negative breast cancers.

  7. Role of radiotherapy and prognostic factors in breast cancer patients at high-risk of recurrence treated with modified radical mastectomy and chemotherapy

    International Nuclear Information System (INIS)

    Objective: To analyze the outcome and prognostic factors in breast cancer at high-risk of recurrence and evaluate the role of radiotherapy. Methods: 381 breast cancer patients treated with mastectomy and axillary dissection were retrospectively analyzed. The including criterias were pathologic diagnosis of invasive breast cancer, T3-T4 and/or four or more positive axillary nodes. The survival rates was calculated by Kaplan-Meier method, and compared by Logrank test. Cox regression model was used to select potential prognostic variables. Results: The median follow up was 48 months. The 5-year overall survival (OS) and locoregional recurrence-free survival (LRFS) rates were 76.8% and 89.7%, respectively. Radiotherapy significantly improved the OS (80.9% vs. 62.3%, χ2=15.47, P=0.001) and LRFS (93.4% vs. 77.1%, χ2=19.95, P=0.000). The use of ipsilateral chest wall and supraclavicular nodal radiation was associated with increased 5-year chest wall recurrence free survival (96.8%: 86.2%, χ2=12.66, P= 0.001) and 5-year supraclavicular node recurrence free survival (97.7% :90.7%, χ2=9.98, P=0.002). However, axillary irradiation had no impact on 5-year axillary recurrence free survival (98.4%:96.1%, χ=0.74, P=0.389). In multivariate analysis, absence of radiotherapy (χ2=14.42, P=0.000), 10 or more positive axillary nodes (χ2=21.60, P=0.000), and T4 stage (χ2=10.79, P=0.001) were independent unfavorable prognostic factors for overall survival. Conclusions: Radiotherapy improves the overall survival of breast cancer patients with T3, T4 and/or four or more positive axillary nodes. The chest wall and supraclavicular nodal radiation should be given to this group of patients. (authors)

  8. Atypical and Malignant Meningioma: Outcome and Prognostic Factors in 119 Irradiated Patients. A Multicenter, Retrospective Study of the Rare Cancer Network

    International Nuclear Information System (INIS)

    Purpose: To retrospectively analyze and assess the outcomes and prognostic factors in a large number of patients with atypical and malignant meningiomas. Methods and Materials: Ten academic medical centers participating in this Rare Cancer Network contributed 119 cases of patients with atypical or malignant meningiomas treated with external beam radiotherapy (EBRT) after surgery or for recurrence. Eligibility criteria were histologically proven atypical or anaplastic (malignant) meningioma (World Health Organization Grade 2 and 3) treated with fractionated EBRT after initial resection or for recurrence, and age >18 years. Sex ratio (male/female) was 1.3, and mean (±SD) age was 57.6 ± 12 years. Surgery was macroscopically complete (Simpson Grades 1-3) in 71% of patients; histology was atypical and malignant in 69% and 31%, respectively. Mean dose of EBRT was 54.6 ± 5.1 Gy (range, 40-66 Gy). Median follow-up was 4.1 years. Results: The 5- and 10-year actuarial overall survival rates were 65% and 51%, respectively, and were significantly influenced by age >60 years (p = 0.005), Karnofsky performance status (KPS) (p = 0.01), and high mitotic rate (p = 0.047) on univariate analysis. On multivariate analysis age >60 years (p = 0.001) and high mitotic rate (p = 0.02) remained significant adverse prognostic factors. The 5- and 10-year disease-free survival rates were 58% and 48%, respectively, and were significantly influenced by KPS (p 0.04) and high mitotic rate (p = 0.003) on univariate analysis. On multivariate analysis only high mitotic rate (p = 0.003) remained a significant prognostic factor. Conclusions: In this multicenter retrospective study, age, KPS, and mitotic rate influenced outcome. Multicenter prospective studies are necessary to clarify the management and prognostic factors of such a rare disease

    Full Text Available Introduction: Growth, proliferation, survival, and differentiation are the prominent characteristics of cells, which are affected by cancer. Epidermal growth factor receptor (EGFR plays a pivotal role in the effective control of these features. Given the significance of EGFR signaling pathway in non-small cell lung cancer (NSCLC, EGFR expression is influential on these cell characteristics. In this paper, we studied EGFR expression and its association with demographic factors, clinicopathological features, and prognosis of NSCLC patients. Materials and Methods: In this retrospective cohort study which was done during 2009-12 at Ghaem Hospital, Mashhad, Iran. EGFR expression was evaluated in 96 patients with formalin-fixed, paraffin-embedded NSCLC tissues (43 adenocarcinomas, 48 squamous-cell carcinomas, and 5 large-cell carcinomas using immunohistochemistry (IHC. Data analysis was performed by SPSS version 20.0. Results: Out of 96 specimens, approximately 53% were classified as positive for EGFR expression. The study group consisted of 68% (N=65 male and 32% (N=31 female subjects, with the mean age of 61.1±9.03 years. There was no difference between EGFR-positive and EGFR-negative patients in terms of the overall survival rate (P=0.49. In addition, no association was observed between tumor histology and EGFR expression (P=0.08, while EGFR-positive adenocarcinoma (N=28, 29% was more prevalent compared to other subtypes of NSCLC. Moreover, there were no differences between tumor subtypes and the overall survival rate of the patients (P=0.21, and no association was found between EGFR expression and the patients’ demographic factors (e.g. age and gender. Conclusion: The results of this study indicated that EGFR expression could not be a prognostic marker in NSCLC patients; however, it seems that using standardized IHC scoring is likely to yield more reliable data in this regard.

    The present study concerns 140 patients with loco-regional prostatic cancer, treated with external beam irradiation at the CRLC Val-d'Aurelle in Montpellier, France, between 1982 and 1988, with a minimum of 54 months follow-up. The local control after radiotherapy is 78.6%, all stages and histological grades combined. The median overall survival is 114 months and the median disease-free survival 59 months. The most frequent modality of treatment failure is metastatic disease, isolated (32.8%) or combined to local relapse (10%). The rate of urinary intolerance symptoms during treatment was 87.1 and 80.6% for the digestive ones. The late urinary complications and sequellae rate was 21.4% for the cystitis-type and 12.9% for post-radiotherapy urethral structures; the latter has imposed in 2/3 of cases one or more trans-urethral resections that never showed pathological signs of recurrence. Digestive complications and sequellae occurred in 31.3% of the patients; in the latter group there were two internal digestive fistulae which needed surgical treatment and three postradiotherapeutic stenosis of the anal canal. The prognostic factors revealed by statistical analysis are clinical stage, pathological grade for overall and disease-free survival, age for overall survival and trans-urethral resection for disease-free survival, the latter being equally a risk factor for cystitis-type complications and urethral structures.

    Full Text Available Abstract Background Gene expression of peripheral myelin protein 22 (PMP22 and the epithelial membrane proteins (EMPs was found to be differentially expressed in invasive and non-invasive breast cell lines in a previous study. We want to evaluate the prognostic impact of the expression of these genes on breast cancer. Methods In a retrospective multicenter study, gene expression of PMP22 and the EMPs was measured in 249 primary breast tumors by real-time PCR. Results were statistically analyzed together with clinical data. Results In univariable Cox regression analyses PMP22 and the EMPs were not associated with disease-free survival or tumor-related mortality. However, multivariable Cox regression revealed that patients with higher than median PMP22 gene expression have a 3.47 times higher risk to die of cancer compared to patients with equal values on clinical covariables but lower PMP22 expression. They also have a 1.77 times higher risk to relapse than those with lower PMP22 expression. The proportion of explained variation in overall survival due to PMP22 gene expression was 6.5% and thus PMP22 contributes equally to prognosis of overall survival as nodal status and estrogen receptor status. Cross validation demonstrates that 5-years survival rates can be refined by incorporating PMP22 into the prediction model. Conclusions PMP22 gene expression is a novel independent prognostic factor for disease-free survival and overall survival for breast cancer patients. Including it into a model with established prognostic factors will increase the accuracy of prognosis.

  14. [18F]FDG-PET/CT metabolic parameters as useful prognostic factors in cervical cancer patients treated with chemo-radiotherapy

    International Nuclear Information System (INIS)

    To compare the prognostic value of different anatomical and functional metabolic parameters determined using [18F]FDG-PET/CT with other clinical and pathological prognostic parameters in cervical cancer (CC). Thirty-eight patients treated with standard curative doses of chemo-radiotherapy (CRT) underwent pre- and post-therapy [18F]FDG-PET/CT. [18F]FDG-PET/CT parameters including mean tumor standardized uptake values (SUV), metabolic tumor volume (MTV) and tumor glycolytic volume (TGV) were measured before the start of CRT. The post-treatment tumor metabolic response was evaluated. These parameters were compared to other clinical prognostic factors. Survival curves were estimated by using the Kaplan-Meier method. Cox regression analysis was performed to determine the independent contribution of each prognostic factor. After 37 months of median follow-up (range, 12–106), overall survival (OS) was 71 % [95 % confidence interval (CI), 54–88], disease-free survival (DFS) 61 % [95 % CI, 44–78] and loco-regional control (LRC) 76 % [95 % CI, 62–90]. In univariate analyses the [18F]FDG-PET/CT parameters unfavorably influencing OS, DFS and LRC were pre-treatment TGV-cutoff ≥562 (37 vs. 76 %, p = 0.01; 33 vs. 70 %, p = 0.002; and 55 vs. 83 %, p = 0.005, respectively), mean pre-treatment tumor SUV cutoff ≥5 (57 vs. 86 %, p = 0.03; 36 vs. 88 %, p = 0.004; 65 vs. 88 %, p = 0.04, respectively) and a partial tumor metabolic response after treatment (9 vs. 29 %, p = 0.0008; 0 vs. 83 %, p < 0.0001; 22 vs. 96 %, p < 0.0001, respectively). After multivariate analyses a partial tumor metabolic response after treatment remained as an independent prognostic factor unfavorably influencing DFS and LRC (RR 1:7.7, p < 0.0001, and RR 1:22.6, p = 0.0003, respectively) while the pre-treatment TGV-cutoff ≥562 negatively influenced OS and DFS (RR 1:2, p = 0.03, and RR 1:2.75, p = 0.05).

    Full Text Available To estimate the extent of local tumor spread is a main goal in the diagnosis of prostate cancer (PC. The value of this criterion is that its clinical stage plays a key role in choosing a treatment policy. Overestimation of the clinical stage of cancer leads to the fact that specialists refuse radical and its underestimation gives rise to its recurrence. Our trial defined criteria for the diagnostic efficiency of magnetic resonance imaging (MRI in 150 PC patients who had undergone radical prostatectomy. The findings were as follows: the diagnostic sensitivity of the method in determining the spread of the cancer beyond the organ was 76.8 %; its diagnostic specificity and accuracy were 80.2 and 78.7 %, respectively. The positive predictive value in detecting the extra-organ spread of the tumor was equal to 76.8 %; the negative predictive value was 80.2 %. A prognostic classification of a risk for locally advanced PS has been developed using the independent clinical and MRI signs found.

  16. Evaluation of an Optimal Cut-Off Point for the Ki-67 Index as a Prognostic Factor in Primary Breast Cancer: A Retrospective Study.

    Rumiko Tashima

    Full Text Available The Ki-67 index is an important biomarker for indicating the proliferation of cancer cells and is considered to be an effective prognostic factor for breast cancer. However, a standard cut-off point for the Ki-67 index has not yet been established. Therefore, the aim of this retrospective study was to determine an optimal cut-off point in order to establish it as a more accurate prognostic factor. Immunohistochemical analysis of the Ki-67 index was performed on 4329 patients with primary breast cancer from August 1987 to March 2012. Out of this sample, there were 3186 consecutive cases from September 1997 with simultaneous evaluations of ER, PgR and HER2 status. Cox's proportional hazard model was used to perform univariate and multivariate analyses of the factors related to OS. The hazard ratios (HR and the p values were then compared to determine the optimal cut-off point for the Ki-67 index. The median Ki-67 index value was 20.5% (mean value 26.2%. The univariate analysis revealed that there was a statistically significant negative correlation with DFS and OS and the multivariate analysis revealed that the Ki-67 index value was a significant factor for DFS and OS. The top seven cut-off points were then carefully chosen based on the results of the univariate analysis using the lowest p-values and the highest HR as the main selection criteria. The multivariate analysis of the factors for OS showed that the cut-off point of 20% had the highest HR in all of the cases. However, the cutoff point of 20% was only a significant factor for OS in the Luminal/HER2- subtype. There was no correlation between the Ki-67 index value and OS in any of the other subtypes. These data indicate that the optimal cut-off point of 20% is the most effective prognostic factor for Luminal/HER2- breast cancer.

  19. A retrospective comparative exploratory study on two Methylentetrahydrofolate Reductase (MTHFR) polymorphisms in esophagogastric cancer: the A1298C MTHFR polymorphism is an independent prognostic factor only in neoadjuvantly treated gastric cancer patients

    International Nuclear Information System (INIS)

    Methylentetrahydrofolate reductase (MTHFR) plays a major role in folate metabolism and consequently could be an important factor for the efficacy of a treatment with 5-fluorouracil. Our aim was to evaluate the prognostic and predictive value of two well characterized constitutional MTHFR gene polymorphisms for primarily resected and neoadjuvantly treated esophagogastric adenocarcinomas. 569 patients from two centers were analyzed (gastric cancer: 218, carcinoma of the esophagogastric junction (AEG II, III): 208 and esophagus (AEG I): 143). 369 patients received neoadjuvant chemotherapy followed by surgery, 200 patients were resected without preoperative treatment. The MTHFR C677T and A1298C polymorphisms were determined in DNA from peripheral blood lymphozytes. Associations with prognosis, response and clinicopathological factors were analyzed retrospectively within a prospective database (chi-square, log-rank, cox regression). Only the MTHFR A1298C polymorphisms had prognostic relevance in neoadjuvantly treated patients but it was not a predictor for response to neoadjuvant chemotherapy. The AC genotype of the MTHFR A1298C polymorphisms was significantly associated with worse outcome (p = 0.02, HR 1.47 (1.06-2.04). If neoadjuvantly treated patients were analyzed based on their tumor localization, the AC genotype of the MTHFR A1298C polymorphisms was a significant negative prognostic factor in patients with gastric cancer according to UICC 6th edition (gastric cancer including AEG type II, III: HR 2.0, 95% CI 1.3-2.0, p = 0.001) and 7th edition (gastric cancer without AEG II, III: HR 2.8, 95% CI 1.5-5.7, p = 0.003), not for AEG I. For both definitions of gastric cancer the AC genotype was confirmed as an independent negative prognostic factor in cox regression analysis. In primarily resected patients neither the MTHFR A1298C nor the MTHFR C677T polymorphisms had prognostic impact. The MTHFR A1298C polymorphisms was an independent prognostic factor in patients with

  1. Exclusive brachytherapy for T1-T2 N0 cancer of the oral tongue: prognostic factors for local control

    International Nuclear Information System (INIS)

    INTRODUCTION: The files of a group of patients (pts) treated with brachytherapy alone for cancer of the oral tongue were reviewed to assess the prognostic role of T stage, volume of disease, total dose and dose-rate. PATIENTS METHODS AND RESULTS: From 1982 to 1994 46 pts (29 males, 17 females, age 38-84 years, median 63.1 years) were treated with 192 Ir brachytherapy, in 2 cases followed by prophylactic neck dissection for cancer of the oral tongue (T1N0: 19 pts; T2N0: 27 pts). Brachytherapy was performed with hairpins in the early years of the study (17 pts) and more recently with plastic tubes (29 pts), according to the Parts System. Dose ranged from 60-70 Gy with a dose-rate of 0.38-0.62 Gy/h (median 63.8 and 0.52 respectively). Volume of the disease was retrospectively assessed as the product of the three diameters of the lesion calculated for provisional dosimetry (range 0.25- 16 cc.). Median follow up is 72 mos (range: 14-153 mos). RESULTS: Overall local control was 82.6% ((38(46)) pts; T1: (18(19)), 94.7 %; T2: (22(27)), 81.5 %). Five of 8 pts who recurred were submitted to salvage surgery, and 3 of them are alive and free from disease at 34, 52 and 87 mos respectively. Recurrences appeared after 3-13 mos (median 5.5 mos) and were related to total dose ( 63 Gy (1(18)); 5.5 %) and to dose-rate ( 45 cGy/h (4(36)): 11.1 %). The volume of disease was not of prognostic significance since local control was 79.6 % ((6(28)) pts) in pts with a disease smaller than 3 cc. and 88.9 % in pts with large volume ((2(18)) pts). Seven (15.2 %) grade 3 complications (necrosis of the mandibular bone and- or of the soft tissues) were observed. Complication rate was higher in the high dose group (>63 Gy (4(18)) pts: 22.2 %) and was less affected by dose-rate (> 45 cGy/h (6(36)) pts: 16.6 %). No relationship between complications and volume was observed ( 3cc.: 16.6 %). All complications healed spontaneously. DISCUSSION AND CONCLUSION: For T1-T2 cancer of the oral tongue exclusive

    Purpose: Vascular endothelial growth factor (VEGF) is an important protein involved in the process of angiogenesis that has been found to correlate with relapse-free and overall survival in breast cancer, predominantly in locally advanced and metastatic disease. A paucity of data is available on the prognostic implications of VEGF in early-stage breast cancer; specifically, its prognostic value for local relapse after breast-conserving therapy (BCT) is largely unknown. The purpose of our study was to assess VEGF expression in a cohort of early-stage breast cancer patients treated with BCT and to correlate the clinical and pathologic features and outcomes with overexpression of VEGF. Methods and Materials: After obtaining institutional review board approval, the paraffin specimens of 368 patients with early-stage breast cancer treated with BCT between 1975 and 2005 were constructed into tissue microarrays with twofold redundancy. The tissue microarrays were stained for VEGF and read by a trained pathologist, who was unaware of the clinical details, as positive or negative according the standard guidelines. The clinical and pathologic data, long-term outcomes, and results of VEGF staining were analyzed. Results: The median follow-up for the entire cohort was 6.5 years. VEGF expression was positive in 56 (15%) of the 368 patients. Although VEGF expression did not correlate with age at diagnosis, tumor size, nodal status, histologic type, family history, estrogen receptor/progesterone receptor status, or HER-2 status, a trend was seen toward increased VEGF expression in the black cohort (26% black vs. 13% white, p = .068). Within the margin-negative cohort, VEGF did not predict for local relapse-free survival (RFS) (96% vs. 95%), nodal RFS (100% vs. 100%), distant metastasis-free survival (91% vs. 92%), overall survival (92% vs. 97%), respectively (all p >.05). Subset analysis revealed that VEGF was highly predictive of local RFS in node-positive, margin

    Growing cancer incidence and mortality worldwide demands development of accurate biomarkers to perfect detection, diagnosis, prognostication and monitoring. Urologic (prostate, bladder, kidney), lung, breast and colorectal cancers are the most common and despite major advances in their characterization, this has seldom translated into biomarkers amenable for clinical practice. Epigenetic alterations are innovative cancer biomarkers owing to stability, frequency, reversibility and accessibility in body fluids, entailing great potential of assay development to assist in patient management. Several studies identified putative epigenetic cancer biomarkers, some of which have been commercialized. However, large multicenter validation studies are required to foster translation to the clinics. Herein we review the most promising epigenetic detection, diagnostic, prognostic and predictive biomarkers for the most common cancers.

    Purpose: To investigate the association between non-mass type breast cancer and common clinical–pathological prognostic factors, compared with mass type breast cancer. Materials and methods: After institutional review board approval, retrospective blind review of contrast-enhanced breast MRI was carried out for 88 histologically proven breast invasive ductal carcinoma (IDC) patients, presenting from January 2008 to December 2011. Two radiologists assessed the images of each lesion for the morphologic enhancement type [mass enhancement or non-mass-like enhancement (NMLE)] and the distribution/internal enhancement of NMLE. Two pathologists evaluated the histological grade of IDC, presence or absence of ductal carcinoma in situ (DCIS), lymph node status, presence or absence of vascular invasion, and expression status of estrogen receptor (ER)/progesterone receptor (PR)/HER-2/p53 tumor suppressor gene (p53)/Ki-67. Inter-observer agreement was assessed with kappa test. Chi-square test and Spearman rank correlation were performed to explore the associations of morphologic enhancement type with the age, lesion size and the above pathological prognostic factors Results: Inter-observer agreement was excellent, with kappa > 0.75. Morphologic enhancement type was significantly correlated with age (P = 0.02), with NMLE more commonly seen in women less than 50 y/o. The size of NMLE was larger than that of mass and, with the increase of lesion size, proportion of NMLE among the cases increased (P = 0.001). NMLE was also significantly correlated with low histologic grade of IDC (P = 0.003) and presence of DCIS (P < 0.001). There was no significant correlation between morphologic enhancement type and lymph node status, vascular invasion, ER/PR/HER-2/p53/Ki-67 status. The histological grade was higher in clumped enhancement than non-clumped (P = 0.011). There was no correlation between enhancement distribution and prognostic factors Conclusions: Non-mass type breast cancer may

    AIM: To identify the prognostic factors with regard to survival for patients with brain metastasis from primary tumors of the gastrointestinal tract.METHODS: Nine hundred and sixteen patients with brain metastases, treated with whole brain radiation therapy (WBRT) between January 1985 and December 2000 at the Department of Radiation Oncology, University Hospital Freiburg, were analyzed retrospectively.RESULTS: Fifty-seven patients presented with a primary tumor of the gastrointestinal tract (esophagus: n = 0, stomach:n = 10, colorectal: n = 47). Twenty-six patients had a solitary brain metastasis, 31 patients presented with multiple brain metastases. Surgical resection was performed in 25 patients.WBRTwas applied with daily fractions of 2 Gray (Gy) or 3 Gy to a total dose of 50 Gy or 30 Gy, respectively. The interval between diagnoses of the primary tumors and brain metastases was 22.6 mo vs8.0 mo for patients with primary tumors of the colon/rectum vs other primary tumors,respectively (P<0.01, log-rank). Median overall survival for all patients with brain metastases (n = 916) was 3.4 mo and 3.2 mo for patients with gastrointestinal neoplasms.Patients with gastrointestinal primary tumors presented significantly more often with a solitary brain metastasis than patients with other primary tumors (P<0.05, log-rank). In patients with gastrointestinal neoplasms (n = 57), the median overall survival was 5.8 mo for patients with solitary brain metastasis vs 2.7 mo for patients with multiple brain metastases (P<0.01, log-rank). The median overall survival for patients with a Karnofsky performance status (KPS) ≥70was 5.5 mo vs2.1 mo for patients with KPS <70 (P<0.01,log-rank). At multivariate analysis (Cox Model) the performance status and the number of brain metastases were identified as independent prognostic factors for overall survival.CONCLUSION: Brain metastases occur late in the course of gastrointestinal tumors. Pretherapeutic variables like KPS and the

    Autophagy is a process that degrades intracellular constituents, such as long-lived or damaged proteins and organelles, to buffer metabolic stress under starvation conditions. Deregulation of autophagy is involved in the progression of cancer. However, the predictive value of autophagy for breast cancer prognosis remains unclear. First, based on gene expression profiling, we found that autophagy genes were implicated in breast cancer. Then, using the Cox proportional hazard regression model, we detected autophagy prognostic signature for breast cancer in a training dataset. We identified a set of eight autophagy genes (BCL2, BIRC5, EIF4EBP1, ERO1L, FOS, GAPDH, ITPR1 and VEGFA) that were significantly associated with overall survival in breast cancer. The eight autophagy genes were assigned as a autophagy-related prognostic signature for breast cancer. Based on the autophagy-related signature, the training dataset GSE21653 could be classified into high-risk and low-risk subgroups with significantly different survival times (HR = 2.72, 95% CI = (1.91, 3.87); P = 1.37 × 10(-5)). Inactivation of autophagy was associated with shortened survival of breast cancer patients. The prognostic value of the autophagy-related signature was confirmed in the testing dataset GSE3494 (HR = 2.12, 95% CI = (1.48, 3.03); P = 1.65 × 10(-3)) and GSE7390 (HR = 1.76, 95% CI = (1.22, 2.54); P = 9.95 × 10(-4)). Further analysis revealed that the prognostic value of the autophagy signature was independent of known clinical prognostic factors, including age, tumor size, grade, estrogen receptor status, progesterone receptor status, ERBB2 status, lymph node status and TP53 mutation status. Finally, we demonstrated that the autophagy signature could also predict distant metastasis-free survival for breast cancer.

PC is a clinically highly heterogeneous disease, and distinction between aggressive and indolent disease is a major challenge for the management of PC. Currently, no biomarkers or prognostic tools are able to accurately predict tumor progression at the time of diagnosis. Thus, improved biomarkers for PC prognosis are urgently needed. This review focuses on the prognostic potential of DNA methylation biomarkers for PC. Epigenetic changes are hallmarks of PC and associated with malignant initiation as well as tumor progression. Moreover, DNA methylation is the most frequently studied epigenetic alteration in PC, and the prognostic potential of DNA methylation markers for PC has been demonstrated in multiple studies. The most promising methylation marker candidates identified so far include PITX2, C1orf114 (CCDC181 and the GABRE~miR-452~miR-224 locus, in addition to the three-gene signature AOX1/C1orf114/HAPLN3. Several other biomarker candidates have also been investigated, but with less stringent clinical validation and/or conflicting evidence regarding their possible prognostic value available at this time. Here, we review the current evidence for the prognostic potential of DNA methylation markers in PC.

    Background and Purpose: Controversies regarding the optimal therapy for patients with locally advanced pancreatic cancer (LAPC) exist. Although the prognosis as a whole remains dismal, subgroups are known to benefit from intensive therapy, including chemoradiotherapy (CRT). We describe the results in 178 patients treated from 2001 to 2010 and have developed a prognostic model for both survival and the possibility of a subsequent resection in these patients. Methods and Materials: From 2001 until 2010, 178 consecutive patients with LAPC were treated and included in the present study, with CRT consisting of 50 Gy in 27 fractions combined with tegafur-uracil(UFT)/folinic acid(FA). Results: The median survival from diagnosis was 11.5 months. Adverse events of Grade 3 or above were seen in 36% of the patients. Ninety-three percent of the patients completed all fractions. A Cox regression model for survival demonstrated resection (hazard ratio [HR] 0.12; 95% confidence interval [CI], 0.1-0.3) and pre-CRT gemcitabine-based therapy (HR 0.57; 95% CI, 0.4-0.9) as being associated with a favorable outcome, increasing gross tumor volume (HR 1.14; 95% CI, 1.0-1.3) was associated with shorter survival. A logistic regression model showed Stage III disease (odds ratio [OR] 0.16; 95% CI, 0.0-1.1) and abnormal hemoglobin (OR 0.26; 95% CI, 0.0-1.2) as being associated with lower odds of resection. Conclusion: This study confirms the favorable prognosis for patients receiving gemcitabine therapy before CRT and the poor prognosis associated with increasing tumor volume. In addition, CRT in patients with abnormal hemoglobin and Stage III disease rarely induced tumor shrinkage allowing subsequent resection.

  16. Baseline neutrophil-lymphocyte ratio (≥2.8) as a prognostic factor for patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation

    International Nuclear Information System (INIS)

    The neutrophil-lymphocyte ratio (NLR) has been proposed as an indicator of systemic inflammatory response and may predict the clinical outcome in some cancers, such as head and neck cancer and gastric cancer. However, the value of this ratio is variable in different cancers. Studies of the relationship between NLR and both survival and response to chemoradiation have been limited with respect to locally advanced rectal cancer. From 2006 to 2011, 199 consecutive locally advanced rectal cancer patients who were treated with neoadjuvant chemoradiation in the Shanghai Cancer Center were enrolled and analysed retrospectively. Tumor response was evaluated by pathological findings. The baseline total white blood cell count (WBC) and the neutrophil, lymphocyte, platelet counts were recorded. The neutrophil-lymphocyte ratio (NLR) and the relationship with clinical outcomes such as overall survival (OS) and disease-free survival (DFS) was analyzed. With ROC analysis, the baseline NLR value was found to significantly predict prognosis in terms of OS well in locally advanced rectal cancer patients. A multivariate analysis identified that a cut-off value of NLR ≥ 2.8 could be used as an independent factor to indicate decreased OS (HR, 2.123; 95% CI, 1.140-3.954; P = 0.018). NLR ≥ 2.8 was also associated with worse DFS in univariate analysis (HR, 1.662; 95% CI, 1.037-2.664; P = 0.035), though it was not significant in the multivariate analysis (HR, 1.363; 95% CI, 0.840-2.214; P = 0.210). There was no observed significant correlation of mean value of NLR to the response to neoadjuvant chemoradiation. The mean NLR in the ypT0-2 N0 group was 2.68 ± 1.38, and it was 2.77 ± 1.38 in the ypT3-4/N+ group, with no statistical significance (P = 0.703). The mean NLR in the TRG 0–1 group was 2.68 ± 1.42, and it was 2.82 ± 1.33 in the TRG 2–3 group with no statistical significance (P = 0.873). An elevated baseline NLR is a valuable and easily available prognostic factor for OS in

  17. Prognostic factors for disease-free survival in patients with T-4 or N+ rectal cancer treated with preoperative chemoradiation therapy, surgery, and intraoperative irradiation

    International Nuclear Information System (INIS)

    Purpose: Fluoropyrimidine-radiosensitizing agents in conjunction with preoperative radiotherapy have proven to induce tumor and nodal downstaging effects, sphincter preservation promotion, and mid-term favorable survival rates. Intraoperative electron beam radiation therapy may improve pelvic control in patients with locally advanced rectal cancer stages. Potential predictive factors for response and disease-free survival, with intense local multidisciplinary approach, are analyzed. Methods and Materials: One hundred fifteen patients with rectal cancer were treated with oral 5-fluorouracil or Tegafur with preoperative radiotherapy, surgery, and intraoperative electron beam radiation therapy to identify potential pre- and on-treatment characteristics that might be of prognostic value for disease outcome. Univariate and multivariate analyses were performed. Results: Older patients and those treated with Tegafur were more likely to achieve a major histologic response, categorized as persistence of minimal residual microscopic disease foci in the surgical specimen ('mic' response). Factors unfavorably associated with disease-free survival in the multivariate model were male gender and persistence of macroscopic disease in the rectal wall ('mac' response). Accordingly, 3-year disease-free survival rates in the groups of patients with 0, 1, or 2 of these risk factors were 100%, 81%, and 53%, respectively (p mic residue) to preoperative chemoradiotherapy have an excellent 3-year disease-free survival. This information might be of interest for stratification of patients in the development of adjuvant treatment trials

    The purpose of this study was to investigate whether a correlation exists between {sup 18}F-fluorodeoxyglucose (FDG) uptake and prognostic factors in triple-negative breast cancer (TNBC). Between January 2009 and December 2013, 103 patients (mean age, 50.6 years) with primary TNBC (mean, 2.6 cm; range, 1.0-6.5 cm) underwent {sup 18}F-FDG PET/CT for initial staging. Correlations between maximum standardized uptake value (SUV{sub max}) on PET/CT and prognostic factors including tumour size, nodal status, histological grade, Ki-67 proliferation index, tumour suppressor p53, and 'basal-like' markers (epidermal growth factor receptor and CK 5/6) were assessed. The mean SUV{sub max} of the 103 tumours was 10.94 ± 5.25 (range: 2-32.8). There was a positive correlation between SUV{sub max} and Ki-67 (Spearman's rho = 0.29, P = 0.003) and tumour size (Spearman's rho = 0.27, P = 0.006), whereas this relationship was not observed in the nodal status, histological grade, p53 status and 'basal-like' phenotypes. In a multivariate regression analysis, Ki-67 (P < 0.001) and tumour size (P = 0.009) were significantly associated with SUV{sub max} in TNBCs. Increased {sup 18}F-FDG uptake on PET/CT was correlated with a high Ki-67 proliferation index and larger tumour size in TNBC. These results suggest a potential role of {sup 18}F-FDG PET/CT in identifying TNBC with more aggressive behaviour. (orig.)

    Clinical trials have provided conflicting results regarding whether epidermal growth factor receptor (EGFR) overexpression predicts poor survival in cervical cancer patients. In this study, we perform a meta-analysis of the association between EGFR expression and survival in cervical cancer patients. We searched clinical studies in the Medline, PubMed, Embase, and Web of Science databases. A total of 22 studies with 2,505 patients were included, and pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated for each study. Heterogeneity was assessed using Higgins I2 to select a Mantel-Haenszel fixed effects model (I2 ≤50%) or a DerSimonian-Laird random effects model (I2 ≥50%). High EGFR levels predicted poor overall survival (OS) (HR: 1.40, 95% CI: 1.10–1.78) and disease-free survival (DFS) (HR: 1.84, 95% CI: 1.51–2.24). Stratified analyses showed that EGFR overexpression was significantly related to poor DFS in patients treated with chemoradiation or surgery. Moreover, the pooled odds ratios (ORs) revealed associations between EGFR expression and clinicopathological features, such as lymph node metastasis (OR: 1.72, 95% CI: 1.23–2.40) and tumor size ≥4 cm (OR: 1.64, 95% CI: 1.20–2.23). This meta-analysis demonstrates that EGFR overexpression is closely associated with reduced survival in patients with cervical cancer. These results may facilitate the individualized management of clinical decisions for anti-EGFR therapies in cervical cancer patients. PMID:27438047

    To determine whether magnetic resonance imaging (MRI)-detected extramural vascular invasion (EMVI) could predict synchronous distant metastases in rectal cancer. Patients who underwent rectal MRI between July 2011 and December 2012 were screened. This study included 447 patients with pathologically confirmed rectal adenocarcinoma who had undergone MRI without previous treatment. Distant metastases were recorded at the initial work-up and over a 6-month follow-up. Univariate/multivariate logistic regression models were used to determine the risk of metastasis. The diagnostic performance was calculated using pathologic lymphovascular invasion (LVI) as a gold standard. Among 447 patients, 79 patients (17.7 %) were confirmed to have distant metastases. Three MRI features are significantly associated with a high risk of distant metastasis: positive EMVI (odds ratio 3.02), high T stage (odds ratio 2.10) and positive regional lymph node metastasis (odds ratio 6.01). EMVI in a large vessel (≥3 mm) had a higher risk for metastasis than EMVI in a small vessel (<3 mm). Sensitivity, specificity and accuracy of MRI-detected EMVI were 28.2 %, 94.0 % and 80.3 %, respectively. MRI-detected EMVI is an independent risk factor for synchronous metastasis in rectal cancer. EMVI in large vessels is a stronger risk factor for distant metastasis than EMVI in small vessels. (orig.)

    Uterine leiomyosarcomas (LMSs) are rare cancers representing less than 1% of all uterine malignancies. Clinical International Federation of Gynecology and Obstetrics (FIGO) stage is the most important prognostic factor. Other significant prognostic factors, especially for early stages, are difficult to establish because most of the published studies have included localized and extra-pelvian sarcomas. The aim of our study was to search for significant prognostic factors in clinical stage I and II uterine LMS. The pathologic features of 108 uterine LMS including 72 stage I and II lesions were reviewed using standardized criteria. The prognostic significance of different pathologic features was assessed. The median follow-up in the whole group was 64 months (range, 6-223 months). The 5-year overall survival (OS) and metastasis-free interval and local relapse-free interval rates in the whole group and early-stage group (FIGO stages I and II) were 40% and 57%, 42% and 50%, 56% and 62%, respectively. Clinical FIGO stage was the most important prognostic factor for OS in the whole group (P = 4 x 10). In the stage I and II group, macroscopic circumscription was the most significant factor predicting OS (P = 0.001). In the same group, mitotic score and vascular invasion were associated with metastasis-free interval (P = 0.03 and P = 0.04, respectively). Uterine LMSs diagnosed using standardized criteria have a poor prognosis, and clinical FIGO stage is an ominous prognostic factor. In early-stage LMS, pathologic features such as mitotic score, vascular invasion, and tumor circumscription significantly impact patient outcome. PMID:19407564

  4. Development of radiation pneumopathy and generalised radiological changes after radiotherapy are independent negative prognostic factors for survival in non-small cell lung cancer patients

    International Nuclear Information System (INIS)

    Background and purpose: To investigate the risk factors for radiation pneumopathy (RP) and survival rate of non-small cell lung cancer patients with RP and generalised interstitial lung changes (gen-ILC). Material and methods: A total of 147 consecutive patients receiving curative radiotherapy were analysed. RP was graded according to Common Terminology Criteria for Adverse Events v. 3. Computed tomography images were assessed for the presence of gen-ILC after radiotherapy. Univariate and multivariate analyses were performed to identify significant factors. Results: Median follow-up was 16.2 months (range 1.4–58.6). Radiological changes after radiotherapy were confined to high dose irradiation volume in 111 patients, while 31 patients developed gen-ILC. Dosimetric parameters and level of C-reactive protein before radiotherapy were significantly associated with severe RP. Development of gen-ILC (p = 0.008), as well as severe RP (p = 0.03) had significant negative impact on patients’ survival. These two factors remained significant in the multivariate analysis. Conclusions: Severe radiation pneumopathy and generalised radiographic changes were significant independent prognostic factors for survival. More studies on pathophysiology of radiation induced damage are necessary to fully understand the mechanisms behind it

    In order to explore the possibility to predict the risk factors for postoperative complications and survival time, the clinical data of 152 patients (including 116 males and 36 females) who had undergone neo-adjuvant therapy and surgery for stage Ilia and B non-small cell lung cancer (NSCLC) were retrospectively analyzed. Demographic data, preoperative functional parameters,staging, induction regimen (chemotherapy alone or associated with radiotherapy), associated disorders, and data about operation were collected. Chi-square test and multivariate analysis fitting the unconditional logistic regression model were performed to identify predictors of postoperative complications, while Kaplan-Meier and multivariate Cox proportional hazard model were employed to identify predictors of survival time, respectively. The univariate analysis demonstrated that forced expiratory volume in 1 second predicted percent (FEVI%, P=0.040) and associated disorders (P=0.020) were the predictive factors of complications, but multivariate analysis found no independence factors (P>0.05) of it. Univariate Kaplan-Meier analysis showed that stage (P=0.050) and pneumonectomy (P=0.018) affected the survival time. However, multivariate Cox proportional hazard model analysis demonstrated that only pneumonectomy (P=0.026) was associated with a decreased survival time, but no differences between right and left pneumonectomy were found. The results suggest that the risk factor for postoperative complications is acceptable, and pneumonectomy is associated with increased mortality, which should be performed only in stage Ⅲ NSCLC patients.

Statistically significant poor prognostic factors were advanced age (p=0.042, erythrocyte sedimentation rate (p=0.027 and serum albumin level (p=0.007. Conclusion: Advanced age, increased ESR and decreased albumin levels were found as poor prognostic factors in GBS.

  7. Evaluation of Vascular Endothelial Growth Factor as a Prognostic Marker for Local Relapse in Early-Stage Breast Cancer Patients Treated With Breast-Conserving Therapy

    International Nuclear Information System (INIS)

    Purpose: Vascular endothelial growth factor (VEGF) is an important protein involved in the process of angiogenesis that has been found to correlate with relapse-free and overall survival in breast cancer, predominantly in locally advanced and metastatic disease. A paucity of data is available on the prognostic implications of VEGF in early-stage breast cancer; specifically, its prognostic value for local relapse after breast-conserving therapy (BCT) is largely unknown. The purpose of our study was to assess VEGF expression in a cohort of early-stage breast cancer patients treated with BCT and to correlate the clinical and pathologic features and outcomes with overexpression of VEGF. Methods and Materials: After obtaining institutional review board approval, the paraffin specimens of 368 patients with early-stage breast cancer treated with BCT between 1975 and 2005 were constructed into tissue microarrays with twofold redundancy. The tissue microarrays were stained for VEGF and read by a trained pathologist, who was unaware of the clinical details, as positive or negative according the standard guidelines. The clinical and pathologic data, long-term outcomes, and results of VEGF staining were analyzed. Results: The median follow-up for the entire cohort was 6.5 years. VEGF expression was positive in 56 (15%) of the 368 patients. Although VEGF expression did not correlate with age at diagnosis, tumor size, nodal status, histologic type, family history, estrogen receptor/progesterone receptor status, or HER-2 status, a trend was seen toward increased VEGF expression in the black cohort (26% black vs. 13% white, p = .068). Within the margin-negative cohort, VEGF did not predict for local relapse-free survival (RFS) (96% vs. 95%), nodal RFS (100% vs. 100%), distant metastasis-free survival (91% vs. 92%), overall survival (92% vs. 97%), respectively (all p >.05). Subset analysis revealed that VEGF was highly predictive of local RFS in node-positive, margin

    Full Text Available Patients with early-stage lung cancer who have a high baseline lymphocyte-to-monocyte ratio (LMR have a favorable prognosis. However, the prognostic significance of LMR in patients with advanced-stage EGFR-mutant non-small cell lung cancer (NSCLC receiving first-line epidermal growth factor receptor (EGFR-tyrosine kinase inhibitors (TKIs has not been established. We conducted a retrospective analysis to investigate the influence of LMR on clinical outcomes including progression-free survival (PFS and overall survival (OS in EGFR-mutant patients with NSCLC.Of 1310 lung cancer patients diagnosed between January 2011 and October 2013, 253 patients receiving first-line EGFR-TKIs for EGFR-mutant NSCLC were included. The cut-off values for baseline and the 1-month-to-baseline ratio of LMR (MBR, determined by using receiver operating characteristic curves, were 3.29 and 0.63, respectively. Patients were divided into 3 prognostic groups: high LMR and MBR, high LMR or MBR, and low LMR and MBR.The mean patient age was 65.2 years, and 41% were men. The median PFS and OS were 10.3 and 22.0 months, respectively. The PFS in patients with high LMR and MBR, high LMR or MBR, and low LMR and MBR were 15.4, 7.1, and 2.0 months, respectively (p < 0.001, whereas the OS were 32.6, 13.7, and 5.1 months, respectively (p < 0.001.A combination of baseline and trend of LMR can be used to identify patients with a high mortality risk in EGFR-mutant NSCLC patients receiving first-line EGFR-TKIs.

    Survival and prognostic variables in patients with advanced or metastatic non-small cell lung cancer (NSCLC) requiring thoracic palliative radiotherapy using a moderately hypofractionated regime (13-15 x 3 Gy) were evaluated. From March 2006 to April 2012, 120 patients with a physician estimated prognosis of 6-12 months were treated with this regime using CT-based 3D conformal radiotherapy. We collected data on patient characteristics, comorbidities, toxicity, and treatment parameters. Radiotherapy was completed as prescribed in 114 patients (95.0 %, premature termination 5.0 %). Acute grade 3 toxicity was seen in 6.4 % of patients. The median survival of all patients was 5.8 months. Nonmetastatic patients survived significantly longer than patients with metastatic disease (median 11.7 months vs 4.7 months, p = 0.0001) and 18.6 % of nonmetastatic patients survived longer than 2 years. In 12.7 % radiotherapy started less than 30 days before death and 14.2 % of patients received radiotherapy within 14 days before death. In the multivariate analysis, good general condition, nonmetastatic disease, and a stable or improved general condition at the end of radiotherapy were significant. The treatment parameters, age, and comorbidities were not statistically significant. Our data confirm considerable effectiveness of 13 x 3 Gy with conformal radiotherapy for patients with locally confined NSCLC not fit for radical treatment and raise doubt for this regimen in metastatic patients and ECOG ≥ 2 when burden, acute toxicity, and resources are considered.

  11. CD133 expression is not an independent prognostic factor in stage II and III colorectal cancer but may predict the better outcome in patients with adjuvant therapy

    International Nuclear Information System (INIS)

    Cancer stem cells (CSCs) are notorious for their capacity of tumor progression, metastasis or resistance to chemo-radiotherapy. However, the undisputed role of cancer stem marker, CD133, in colorectal cancers (CRCs) is not clear yet. We assessed 271 surgically-resected stage II and III primary CRCs with (171) and without (100) adjuvant therapy after surgery. CD133 expression was analyzed by immunohistochemical (IHC) staining and real-time RT-PCR. CD133 promoter methylation was quantified by pyrosequencing. The CD133 IHC expression was significantly correlated with mRNA expression (p=0.0257) and inversely correlated with the promoter methylation (p=0.0001). CD133 was expressed more frequently in rectal cancer (p=0.0035), and in moderately differentiated tumors (p=0.0378). In survival analysis, CD133 expression was not significantly correlated with overall survival (OS) (p=0.9689) as well as disease-free survival (DFS) (p=0.2103). However, CD133+ tumors were significantly associated with better OS in patients with adjuvant therapy compared to those without adjuvant therapy (p<0.0001, HR 0.125, 95% CI 0.052-0.299). But the patients with CD133- tumors did not show any significant difference of survival according to adjuvant therapy (p=0.055, HR 0.500, 95% CI 0.247-1.015). In stage II and III CRCs, CD133 IHC expression may signify the benefit for adjuvant therapy although it is not an independent prognostic factor

  12. Neoadjuvant Chemoradiation Therapy Using Concurrent S-1 and Irinotecan in Rectal Cancer: Impact on Long-Term Clinical Outcomes and Prognostic Factors

    International Nuclear Information System (INIS)

    Purpose: To assess the long-term outcomes of patients with rectal cancer who received neoadjuvant chemoradiation therapy (NCRT) with concurrent S-1 and irinotecan (S-1/irinotecan) therapy. Methods and Materials: The study group consisted of 115 patients with clinical stage T3 or T4 rectal cancer. Patients received pelvic radiation therapy (45 Gy) plus concurrent oral S-1/irinotecan. The median follow-up was 60 months. Results: Grade 3 adverse effects occurred in 7 patients (6%), and the completion rate of NCRT was 87%. All 115 patients (100%) were able to undergo R0 surgical resection. Twenty-eight patients (24%) had a pathological complete response (ypCR). At 60 months, the local recurrence-free survival was 93%, disease-free survival (DFS) was 79%, and overall survival (OS) was 80%. On multivariate analysis with a proportional hazards model, ypN2 was the only independent prognostic factor for DFS (P=.0019) and OS (P=.0064) in the study group as a whole. Multivariate analysis was additionally performed for the subgroup of 106 patients with ypN0/1 disease, who had a DFS rate of 85.3%. Both ypT (P=.0065) and tumor location (P=.003) were independent predictors of DFS. A combination of these factors was very strongly related to high risk of recurrence (P<.0001), which occurred most commonly in the lung. Conclusions: NCRT with concurrent S-1/irinotecan produced high response rates and excellent long-term survival, with acceptable adverse effects in patients with rectal cancer. ypN2 is a strong predictor of dismal outcomes, and a combination of ypT and tumor location can identify high-risk patients among those with ypN0/1 disease

    Using integrated PET/CT, we evaluated the prognostic relevance in uterine cervical cancer of preoperative pelvic lymph node (LN) [{sup 18}F]FDG uptake. Patients with FIGO stage IB to IIA uterine cervical cancer were imaged with FDG PET/CT before radical surgery. We used Cox proportional hazards regression to examine the relationship between recurrence and the FDG maximum standardized uptake value (SUV{sub max}) in the pelvic LN (SUV{sub LN}) on PET/CT. Clinical data, treatment modalities, and results in 130 eligible patients were reviewed. The median postsurgical follow-up was 34 months (range 6 to 109 months). Receiver operating characteristic analysis identified SUV{sub LN} 2.36 as the most significant cut-off value for predicting recurrence. SUV{sub LN} was correlated with SUV{sub tumour} (P = 0.002), primary tumour size (P = 0.004), and parametrial invasion (P = 0.013). Univariate analyses showed significant associations between recurrence and SUV{sub LN} (P = 0.001), SUV{sub tumour} (P = 0.007), pelvic LN metastasis (P = 0.002), parametrial invasion (P < 0.001), primary tumour size (P = 0.007), suspected LN metastasis on MRI (P = 0.024), and FIGO stage (P = 0.026). Multivariate analysis identified SUV{sub LN} (P = 0.013, hazard ratio, HR, 4.447, 95 % confidence interval, CI, 1.379 - 14.343) and parametrial invasion (P = 0.013, HR 6.728, 95 % CI 1.497 - 30.235) as independent risk factors for recurrence. Patients with SUV{sub LN} ≥2.36 and SUV{sub LN} <2.36 differed significantly in terms of recurrence (HR 15.20, P < 0.001). Preoperative pelvic LN FDG uptake showed a strong significant association with uterine cervical cancer recurrence. (orig.)

  18. Postmastectomy electron-beam-rotation irradiation in locally advanced breast cancer. Prognostic factors of locoregional tumor control

    International Nuclear Information System (INIS)

    Background: Different radiotherapy techniques are used for postmastectomy irradiation. We review the results with the electron-beam-rotation technique in advanced breast cancer patients. Main endpoint was local tumor control. Patients and Methods: From 1990 to 1998 119 patients with adverse pathology features (pT3 17% of patients, pT4 42%, multicentricity 36%, pN≥3 positive nodes and/or pN1biii 81%, close margins 30%) underwent electron-beam-rotation irradiation of the chest wall with daily fractions of 2.0-2.5 Gy per day to 50 Gy total dose after modified radical mastectomy and axillary lymph nodes dissection. A local boost of 10 Gy and/or irradiation of locoregional lymph nodes were applied depending on the completeness of resection and lymph node involvement. Results: After a median follow-up of 73 months for patients at risk the 5-year local tumor control, local tumor control first event, disease-free, and overall survival were 82%, 92%, 57%, and 63% (Kaplan Meier analysis), respectively. Significant predictors of poor local tumor control were maximal tumor diameter ≥5 cm (p=0.01), 'close margins' or residual tumor (p<0.01), four or more involved axillary lymph nodes (p=0.02), two or more involved lymph node levels (p=0.04), negative estrogen receptor status (p=0.03), and high-grade histopathology (GIIb-III, p<0.01). The subgroup analysis showed a high local failure rate of 37% for high-grade (GIIb-III) and estrogen receptor negative tumors, whereas no local recurrence was found in low-grade (GI-IIa) and receptor positive tumors (p=0.01). The multivariate analysis revealed maximal tumor diameter ≥5 cm, four or more involved axillary lymph nodes and high-grade histopathology (GIIb-III) as independent predictors of poor local tumor control. Conclusion: In high-risk breast cancer patients postmastectomy irradiation with the electron-beam-rotation technique is an effective therapy, resulting in a 5-year local failure rate of 8%. Intensified local therapy

    Full Text Available Despite notable progress made in studying breast cancer (BC, the mechanisms of metastases, in view of the classification into molecular subtypes, in patients with BC remain to be fully uninvestigated, in the presence of a good prognosis in particular. To study novel diagnostic and predictive markers in a new way presents current problems in the pathology of BC. This investigation deals with the expression of osteoprotegerin (OPG in the tumor cells of patients with BC. It enrolled 83 patients with locally advanced BC (T2–4N0–3M0 who had been treated in 2003 to 2010. The inclusion criterion was a histologically verified diagnosis of invasive BC. To study the level of OPG, the investigators conducted an immunohistochemical study of biopsy sections according to the standard protocol. The mean expression of receptor activator of nuclear factor kappa-B (RANK in the BC cells was 18.7 %; itsmedian was 5 % (range, 0–90 %. The patients were divided into 2 groups according to the level of RANK expression: 1 high (higher than the median; 2 low (lower than the median. The high RANK group included 39 patients; the low RANK group comprised 44 patients. Analysis of the clinical and pathological characteristics of BC patients with regard RANK expression did not show any statistically significant differences in the presence or absence of affected regional lymph nodes, T category, and Ki-67 index. The analysis of clinical and pathomorphological and immunohistochemical characteristics in patients with breast cancer, taking into consideration RANK expression level, did not show any statistically significant differences with respect to presence or absence of affected regional lymph nodes, age, T category and Ki-67 index (р > 0.05. However, it revealed the following pattern: the high expression of RANK was more common in patients positive for estrogen and progesterone receptors than in those for negative receptors (p = 0.04.

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    Full Text Available BACKGROUND: Tumor-infiltrating T cells are associated with survival in epithelial ovarian cancer (EOC, but their functional status is poorly understood, especially relative to the different risk categories and histological subtypes of EOC. METHODOLOGY/PRINCIPAL FINDINGS: Tissue microarrays containing high-grade serous, endometrioid, mucinous and clear cell tumors were analyzed immunohistochemically for the presence of lymphocytes, dendritic cells, neutrophils, macrophages, MHC class I and II, and various markers of activation and inflammation. In high-grade serous tumors from optimally debulked patients, positive associations were seen between intraepithelial cells expressing CD3, CD4, CD8, CD45RO, CD25, TIA-1, Granzyme B, FoxP3, CD20, and CD68, as well as expression of MHC class I and II by tumor cells. Disease-specific survival was positively associated with the markers CD8, CD3, FoxP3, TIA-1, CD20, MHC class I and class II. In other histological subtypes, immune infiltrates were less prevalent, and the only markers associated with survival were MHC class II (positive association in endometrioid cases and myeloperoxidase (negative association in clear cell cases. CONCLUSIONS/SIGNIFICANCE: Host immune responses to EOC vary widely according to histological subtype and the extent of residual disease. TIA-1, FoxP3 and CD20 emerge as new positive prognostic factors in high-grade serous EOC from optimally debulked patients.

  3. Risk factors for metastasis to No.14v lymph node and prognostic value of positive 14v lymph node for gastric cancer patients after surgery

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Objective:Lymphadenectomy has been increasingly regarded as standard surgical procedure for advanced gastric cancer (GC), while necessity No.14v lymph node dissection for lower GC is still controversial.Methods: A total of 311 GC patients receiving D1+ (D1+7, 8a, 9) or D2 plus No.14v lymph node dissection in our center were enrolled. Patients were categorized into two groups based on No.14v lymph node status: positive group (PG) and negative group (NG).Results:Fifty patients (16.1%) had No.14v lymph node metastasis. Metastasis to No.4d, No.6 lymph node and distant metastasis were independent variables affecting No.14v lymph node metastasis. Patients with positive No.14v lymph node had a significant lower overall survival (OS) rate than those without (3-year OS, 34.0% vs. 67.0%,P<0.001).Conclusion:GC patients with positive No.4d and No.6 lymph node often metastasis to No.14v lymph node. Status of No.14v lymph node was an independent prognostic factor for GC staged TNM III. Patients with positive No.14v lymph node usually have a poor prognosis, while such patients without distant metastasis may beneift from a curative surgery.

  8. Prognostic impact of CD168 expression in gastric cancer

    International Nuclear Information System (INIS)

    Interactions of stromal hyaluronic acid (HA) with its binding protein RHAMM (receptor for HA-mediated motility) (CD168) have been reported to affect tumor extension and the migration of crucial molecules to promote tumor progression and metastases. Cancerous CD168 expression is correlated with aggressive biological features in several cancers. However, the clinical implications of CD168 positivity in gastric cancer have remained unclear. We examined the CD168 expression of 196 consecutive gastric cancer patients by immunohistochemistry. According to CD168 positivity, the 196 gastric cancer patients were divided into two groups (57 CD168-positive and 139 CD168-negative patients). The correlation between CD168 expression and clinicopathological factors (age, sex, histology, tumor depth, lymph node status, and vessel invasion) was evaluated according to the Japanese Classification of Gastric Carcinoma. Cancerous CD168 expression was detectable in 57 of the 196 tumors (29%). CD168 positivity was significantly correlated with the depth of invasion, nodal involvement, and vessel invasion (p < 0.01). Survival analysis of the 196 gastric cancer patients showed that the CD168-positive group had a significantly higher mortality than the CD168-negative group (p < 0.01). In terms of a correlation with CD168 positivity at separate clinical stages, a significance difference was only found in stages II and III. Multivariate analysis revealed that CD168 expression was a significant independent prognostic marker (p = 0.013) after depth of invasion (p < 0.005) and nodal involvement (p < 0.01). Our results suggest that cancerous CD168 positivity is strongly related to the invasion and metastasis of gastric cancer tumors. These results suggest that cancerous CD168 expression can be used as a prognostic marker of gastric cancer owing to its interactions with stromal hyaluronic acid

    Purpose: The objective of this study was to determine the patient- and treatment-related prognostic factors associated with vaginal toxicity in patients who received intravaginal high dose rate (HDR) brachytherapy alone as adjuvant treatment for endometrial cancer. Secondary goals of this study included a quantitative assessment of optimal dilator use frequency and a crude assessment of clinical predictors for compliant dilator use. Methods and Materials: We retrospectively reviewed the charts of 100 patients with histologically confirmed endometrial cancer who underwent total hysterectomy and bilateral salpingo-oophorectomy with or without lymph node dissection and adjuvant intravaginal brachytherapy between 1995 and 2009 at the Hospital of University of Pennsylvania. The most common treatment regimen used was 21 Gy in three fractions (71 patients). Symptoms of vaginal mucosal toxicity were taken from the history and physical exams noted in the patients' charts and were graded according to the Common Toxicity Criteria for Adverse Events v. 4.02. Results: The incidence of Grade 1 or asymptomatic vaginal toxicity was 33% and Grade 2-3 or symptomatic vaginal toxicity was 14%. Multivariate analysis of age, active length, and dilator use two to three times a week revealed odds ratios of 0.93 (p = 0.013), 3.96 (p = 0.008), and 0.17 (p = 0.032) respectively. Conclusion: Increasing age, vaginal dilator use of at least two to three times a week, and shorter active length were found to be significantly associated with a decreased risk of vaginal stenosis. Future prospective studies are necessary to validate our findings.

    Objective: To identify prognostic factors for patients with T1 to T2 breast cancer and 0 to 3 positive axillary lymph nodes. Methods: Data from 540 breast cancer patients with T1-T2 tumors and 0 to 3 positive nodes were reviewed. The 10-year loco-regional recurrence ( LRR ), distant recurrence ( DR ), disease-free survival ( DFS ) and overall surviral ( OS ) of the patients were analyzed. Univariate statistical analysis and Cox proportional hazards models were carried out using SPSS software v. 16.0. Results: The median follow-up was 7.2 years. In multivariate analysis, the positive rate of over 20% of axillary node was the only variable that adversely influenced LRR ( hazard ratio [ HR ], 12.816; 95% confidence interval, 4.657-35.266, P < 0.00 1 ). The positive rate of over 20% of axillary node and ductal carcinoma were the variables that adversely influenced DR ( HR, 11.088, 95% confidence interval,3.807-32.297, P< 0.001; HR, 0.390, 95% confidence interval, 0.179-0.851, P= 0.018 ). One to 3 positive axillary nodes and the rate of over 20% of positive axillary nodes were the only vaiables that had negative effect on the 10-year OS rate (HR, 2.110, 95% confidence interval, 1.364-3.264, P= 0.001; HR, 10.244, 95% confidence interval, 3.497-30.011, P< 0.001 ) and they were also adverse prognostic factors for thc 10-year DFS ( HR, 1.634, 95% confidence interval, 1.171-2.279, P= 0.004; HR, 7.339, 95% confidence interval,2.906-18.530, P < 0.001 ). Conclusion: The status of axillary lymph node is the only prognostic factor having a significant impact on the 10-year LRR, DR, OS and DFS. Patients with T1-T2 breast cancer and 1 to 3 positive lymph nodes showed higher 10-year LRR and DR, and lower 10-year OS and DFS, compared with patients with negative lymph nodes. The histopathologic results of primary tumors arc the significant prognostic factors for 10-year DR.%目的:研究T1~T2、0~3枚阳性淋巴结乳腺癌患者肿瘤复发和生存

    Purpose: Management of locally advanced rectal cancer (RC) consists of neoadjuvant chemoradiotherapy (CRT) with fluoropyrimidines, followed by total mesorectal excision. We sought to evaluate the expression of selected genes, some of which were derived from a previous undirected SAGE (serial analysis of gene expression)-based approach, before and after CRT, to identify mechanisms of resistance. Methods: This retrospective cohort study included 129 consecutive patients. Quantitative polymerase chain reaction of 53 candidate genes was performed on the biopsy specimen before treatment and on the surgical specimen after CRT. A paired-samples t test was performed to determine genes that were significantly changed after CRT. The result was correlated with patients' disease-free survival. Results: Twenty-two genes were significantly upregulated, and two were significantly downregulated. Several of the upregulated genes have roles in cell cycle control; these include CCNB1IP1, RCC1, EEF2, CDKN1, TFF3, and BCL2. The upregulation of TFF3 was associated with worse disease-free survival on multivariate analyses (hazard ratio, 2.64; P=.027). Patients whose surgical specimens immunohistochemically showed secretion of TFF3 into the lumen of the tumoral microglands had a higher risk of relapse (hazard ratio, 2.51; P=.014). In vitro experiments showed that DLD-1 cells stably transfected with TFF3 were significantly less sensitive to 5-fluorouracil and showed upregulation of genes involved in the transcriptional machinery and in resistance to apoptosis. Conclusion: Upregulation of TFF3 after CRT for RC is associated with a higher risk of relapse. The physiological role of TFF3 in restoring the mucosa during CRT could be interfering with treatment efficacy. Our results could reveal not only a novel RC prognostic marker but also a therapeutic target.

  13. Epigenetic changes of CXCR4 and its ligand CXCL12 as prognostic factors for sporadic breast cancer.

    Directory of Open Access Journals (Sweden)

    Edneia A S Ramos

    Full Text Available Chemokines and their receptors are involved in the development and cancer progression. The chemokine CXCL12 interacts with its receptor, CXCR4, to promote cellular adhesion, survival, proliferation and migration. The CXCR4 gene is upregulated in several types of cancers, including skin, lung, pancreas, brain and breast tumors. In pancreatic cancer and melanoma, CXCR4 expression is regulated by DNA methylation within its promoter region. In this study we examined the role of cytosine methylation in the regulation of CXCR4 expression in breast cancer cell lines and also correlated the methylation pattern with the clinicopathological aspects of sixty-nine primary breast tumors from a cohort of Brazilian women. RT-PCR showed that the PMC-42, MCF7 and MDA-MB-436 breast tumor cell lines expressed high levels of CXCR4. Conversely, the MDA-MB-435 cell line only expressed CXCR4 after treatment with 5-Aza-CdR, which suggests that CXCR4 expression is regulated by DNA methylation. To confirm this hypothesis, a 184 bp fragment of the CXCR4 gene promoter region was cloned after sodium bisulfite DNA treatment. Sequencing data showed that cell lines that expressed CXCR4 had only 15% of methylated CpG dinucleotides, while the cell line that not have CXCR4 expression, had a high density of methylation (91%. Loss of DNA methylation in the CXCR4 promoter was detected in 67% of the breast cancer analyzed. The absence of CXCR4 methylation was associated with the tumor stage, size, histological grade, lymph node status, ESR1 methylation and CXCL12 methylation, metastasis and patient death. Kaplan-Meier curves demonstrated that patients with an unmethylated CXCR4 promoter had a poorer overall survival and disease-free survival. Furthermore, patients with both CXCL12 methylation and unmethylated CXCR4 had a shorter overall survival and disease-free survival. These findings suggest that the DNA methylation status of both CXCR4 and CXCL12 genes could be used as a

    Many studies demonstrate that increased microvessel density (MVD) surrounding primary tumour is associated with decreased overall survival in patients with breast cancer. This study compares the diagnostic and prognostic values of the angiogenic serum factors nitric oxide (NO), tumour necrosis factor-alpha (TNFalpha), basic fibroblast growth factor (bFGF) and copper with those of serum CA15-3 as the standard tumour marker in breast cancer patients. Microvessel density was estimated in CD31-immunostained sections from breast cancer patients. Before surgery, NO, TNFalpha, bFGF, copper and CA 15-3 were measured in serum samples from 30 premenopausal breast cancer patients in comparison with 15 healthy controls. The diagnostic values of the assayed parameters were compared using receiver operating characteristic (ROC) curve analysis. Univariate survival analysis of patients was assessed using the Kaplan-Meier method. Breast cancer tissues showed higher MVD than did normal breast tissues adjacent to the tumour (P = 0.008). Before surgery, tumour MVD correlated significantly with serum NO, TNFalpha, bFGF and copper (r = 0.458, P = .011; r = 0.379, P = .039; r = 0.513, P = .004 and r = 0.613, P = 0.000, respectively). Serum NO, TNFalpha, bFGF, copper and CA 15-3 levels in patients were significantly elevated compared with controls (P = 0.011, P = 0.004, P = 0.039, P = 0.000 and P = 0.001, respectively). Kaplan-Meier analysis revealed that patients with elevated serum TNFalpha, CA 15-3 and copper (P = 0.035, P = 0.040, P = 0.0339, respectively) had an overall survival significantly shorter than those who had lower levels of these parameters. These data suggest that serum TNFalpha, CA 15-3 and copper are useful predictive markers for overall survival in premenopausal breast cancer patients.

Conclusion: 1 This study shows high plasma fibrinogen concentration is associated with lymph nodes or distant organ metastases in lung cancer. 2 Furthermore, our results indicate a significant relevance between high pre-treatment plasma fibrinogen concentration and poor prognosis in patients with lung cancer. 3 In addition, we find that the patients with a low plasma fibrinogen level will have a shorter OS if the plasma fibrinogen level increases significantly after receiving short-term chemotherapy. Interestingly, we also find that the patients with a high plasma fibrinogen level will have a longer OS if the plasma fibrinogen level decreases significantly after receiving short-term chemotherapy, which indicate the change of the plasma fibrinogen level after receiving short-term chemotherapy may be used as an independent prognostic factor.

  17. Which prognostic factors influence the outcome of patients with surgically staged endometrial cancer treated with adjuvant radiation?

    International Nuclear Information System (INIS)

    Purpose: Despite the fact that retrospective reviews have documented pelvic failure rates ranging from 15-20% in patients with high-risk uterine-confined endometrial cancer who have received no or 'inadequate' RT, the role of RT has been questioned. We sought to analyze pelvic control and disease-free survival for a large data base of women with corpus cancers managed with initial surgery followed by adjuvant irradiation. Methods and Materials: Between 1983 and 1993, 294 patients received adjuvant postoperative RT from one of three academic radiation practices. RT consisted of vaginal brachytherapy alone in 28 patients, pelvic RT in 173 patients, pelvic RT with vaginal brachytherapy in 97 patients, and whole abdominal RT in 2 patients. Lymph nodes were evaluated in 49%. The median number of pelvic and periaortic LN in the pathology specimen were 6 and 4, respectively. Median follow up was 63 months. Results: 5-year disease-free survival (DFS) rate and pelvic control rates were 86 and 95%, respectively. Patient-related, treatment-related, and tumor-related characteristics were assessed for the effect on time to relapse. Unfavorable histology, older age, and capillary space invasion were univariately associated with decreased DFS and pelvic control. Pathologic Stage II patients had significantly worse DFS than Stage I patients. Multivariate analysis revealed that age, capillary space invasion, and histology were jointly predictive of disease free survival. Conclusion: The excellent pelvic control and disease-free survival of patients with uterine-confined disease in this series suggest that adjuvant RT should continue for patients with high risk disease. This analysis of a large group of postoperatively treated patients will provide a basis for determining alternative treatment strategies for patients who have an increased risk of disease recurrence despite RT

    To investigate the relationship between early treatment response to definitive chemoradiotherapy (CRT) and survival outcome in patients with limited stage small cell lung cancer (LS-SCLC). We retrospectively reviewed 47 patients with LS-SCLC who received definitive CRT between January 2009 and December 2012. Patients were treated with systemic chemotherapy regimen of etoposide/carboplatin (n = 15) or etoposide/cisplatin (n = 32) and concurrent thoracic radiotherapy at a median dose of 54 Gy (range, 46 to 64 Gy). Early treatment volume reduction rate (ETVRR) was defined as the percentage change in gross tumor volume between diagnostic computed tomography (CT) and simulation CT for adaptive RT planning and was used as a parameter for early treatment response. The median dose at adaptive RT planning was 36 Gy (range, 30 to 43 Gy), and adaptive CT was performed in 30 patients (63.8%). With a median follow-up of 27.7 months (range, 5.9 to 75.8 months), the 2-year locoregional progression-free survival (LRPFS) and overall survival (OS) rates were 74.2% and 56.5%, respectively. The mean diagnostic and adaptive gross tumor volumes were 117.9 mL (range, 5.9 to 447 mL) and 36.8 mL (range, 0.3 to 230.6 mL), respectively. The median ETVRR was 71.4% (range, 30 to 97.6%) and the ETVRR >45% group showed significantly better OS (p < 0.0001) and LRPFS (p = 0.009) than the other group. ETVRR as a parameter for early treatment response may be a useful prognostic factor to predict treatment outcome in LS-SCLC patients treated with CRT.

    This study aims to investigate the correlation between preoperative human epididymis protein 4 (HE4) levels, endometrial cancer (EC) staging, and ideal cutoff for stage prediction. All EC patients, treated within January 2009 and February 2014 at the Division of Gynaecologic Oncology of the University Campus Bio-Medico of Rome, were considered for the study. For the first part of the study, we consider an HE4 cutoff of 70 pmol/L. Histotypes (endometrioid versus non-endometrioid), grading (G1, G2, G3), and stage were correlated with HE4 levels. In the second part of the study, the logistic regression was performed in stepwise mood to identify the ideal HE4 cutoff for stage prediction. Two hundred thirty-two patients with surgically staged EC and preoperative HE4 dosage were included in the study. We found that higher HE4 levels correlate with undifferentiated grading (p IV, respectively, presented HE4 levels above the standard cutoff of 70 pmol/L. Based on receiver operating characteristic (ROC) curves, we found the ideal HE4 cutoff as follows: 61.3 pmol/L for FIGO stage IA (sensitivity = 82.3 % and specificity = 96 %), 89.2 pmol/L for FIGO stage IB (sensitivity = 83.3 % and specificity = 96 %), 104.3 pmol/L for FIGO stage II (sensitivity = 80.9 % and specificity = 98.6 %), 152.6 pmol/L for FIGO stage III (sensitivity = 92.5 % and specificity = 98.6 %), and 203.8 pmol/L for FIGO stage IV (sensitivity = 81.8 % and specificity = 99.3 %). Our results suggest a potential role of HE4 in EC stage prediction.

  4. New Breast Cancer Recursive Partitioning Analysis Prognostic Index in Patients With Newly Diagnosed Brain Metastases

    International Nuclear Information System (INIS)

    Purpose: The aim of the study was to present a new breast cancer recursive partitioning analysis (RPA) prognostic index for patients with newly diagnosed brain metastases as a guide in clinical decision making. Methods and Materials: A prospectively collected group of 441 consecutive patients with breast cancer and brain metastases treated between the years 2003 and 2009 was assessed. Prognostic factors significant for univariate analysis were included into RPA. Results: Three prognostic classes of a new breast cancer RPA prognostic index were selected. The median survival of patients within prognostic Classes I, II, and III was 29, 9, and 2.4 months, respectively (p < 0.0001). Class I included patients with one or two brain metastases, without extracranial disease or with controlled extracranial disease, and with Karnofsky performance status (KPS) of 100. Class III included patients with multiple brain metastases with KPS of ≤60. Class II included all other cases. Conclusions: The breast cancer RPA prognostic index is an easy and valuable tool for use in clinical practice. It can select patients who require aggressive treatment and those in whom whole-brain radiotherapy or symptomatic therapy is the most reasonable option. An individual approach is required for patients from prognostic Class II.

    Using integrated PET/CT, we evaluated the prognostic relevance of preoperative pelvic lymph node (LN) {sup 18}F-FDG uptake in endometrioid endometrial cancer. We retrospectively reviewed patients with pathologically proven endometrial cancer who underwent preoperative {sup 18}F-FDG PET/CT scans to evaluate the prognostic significance of PET/CT parameters and other clinicopathological variables. We used Cox proportional hazards regression to examine the relationship between recurrence and the maximum standardized uptake value (SUV{sub max}) in pelvic LNs (SUV{sub LN}) on FDG PET/CT. Clinical data, treatment modalities and results were reviewed in 70 eligible patients. The median postsurgical follow-up was 29 months (range 6 to 95 months). Receiver-operating characteristic analysis identified the significant SUV{sub LN} cut-off value as 15. The SUV{sub LN} correlated with FIGO stage (P < 0.001), LN metastasis (P < 0.001), lymphovascular space invasion (P < 0.001), SUV{sub tumour} (P = 0.001), metastatic LN size (P = 0.004), primary tumour size (P = 0.012), tumour grade (P = 0.015) and depth of tumour invasion (P = 0.035). Regression analysis showed a statistically significant association between recurrence and SUV{sub LN} (P = 0.002). Recurrence differed significantly (P < 0.001) between patients with SUV{sub LN} >15 and those with SUV{sub LN} ≤15. Preoperative pelvic LN FDG uptake exhibited a strong significant association with recurrence of endometrioid endometrial cancer. (orig.)

    The management of adult patients with grade 2 gliomas remains a challenge for the clinical neuro-oncologist. Several clinical prognostic factors appear to be as important as treatment factors in determining outcome. From the European Organisation for Research and Treatment of Cancer (EORTC) trials 22844 and 22845, a prognostic scoring system has been proposed based on the presence of unfavourable prognostic factors. The aim of the present study was to assess the additional prognostic value of {sup 11}C-methionine (MET) measured by positron emission tomography (PET) in the setting of the EORTC prognostic scoring system. In this retrospective review, 129 patients with supratentorial grade 2 gliomas were subjected to a PET study as part of the pre-treatment tumour investigation. One hundred and three cases were classified as low-risk patients (0-2 unfavourable factors) and 26 cases as high-risk patients (3-5 unfavourable factors) according to the EORTC criteria. MET PET was evaluated as an extra prognostic factor in both groups. In the high-risk group, patients with high MET uptake had a worse outcome than patients with low MET uptake. A similar trend was found for the low-risk group in patients with oligodendrocytic tumours. Our findings further strengthen the role of MET PET as an important prognostic tool in the management of this group of patients. (orig.)

    2013-01-01

    Testicular sperm retrieval techniques associated with intracytoplasmic sperm injection have changed the field of male infertility treatment and given many azoospermic men the chance to become biological fathers. Despite the current use of testicular sperm extraction, reliable clinical and laboratory prognostic factors of sperm recovery are still absent. The objective of this article was to review the prognostic factors and clinical use of sperm retrieval for men with non-obstructive azoospermia. The PubMed database was searched for the Medical Subject Headings (MeSH) terms azoospermia, sperm retrieval, and prognosis. Papers on obstructive azoospermia were excluded. The authors selected articles that reported successful sperm retrieval techniques involving clinical, laboratory, or parenchyma processing methods. The selected papers were reviewed, and the prognostic factors were discussed. No reliable positive prognostic factors guarantee sperm recovery for patients with non-obstructive azoospermia. The only negative prognostic factor is the presence of AZFa and AZFb microdeletions. PMID:23503961

In this study, we investigate the presence of lymphatic vessel invasion (LVI detected by D2-40 immunohistochemical staining in resected esophageal cancer and correlated with clinicopathologic data and patient survival. Sixty nine patients, who had a primary resection of esophageal cancer, were analyzed by univariate and multivariate logistic regression, and univariate and multivariate survival analysis. The total rate of LVI was 72% (50/69. Positive LVI was significantly correlated with lymph node metastasis (p < 0.001, tumor size (p < 0.001, histological grading (p = 0.017, tumor depth (p = 0.001, and stage (p < 0.001. Multivariate logistic analysis identified LVI (p = 0.036 as a predictor of regional lymph node metastasis. On univariate survival analysis, patients with LVI had a significantly shorter disease-free survival, cancer-specific survival and overall survival. Multivariate analysis proved that LVI diagnosed by D2-40 is an independent prognostic factor of both disease-free survival (p = 0.04 and overall survival (p = 0.032 in resected esophageal cancer. These results show that LVI assessment identifies patients at high risk for regional lymph node metastasis and that LVI is an independent prognostic factor in patients with esophageal cancer.

    Although minimally invasive follicular thyroid carcinoma (MI-FTC) is regarded as an indolent tumour, treatment strategies remain controversial. Our aim was to investigate the outcome for patients with MI-FTC and to identify prognostic parameters to facilitate adequate treatment and follow-up. This retrospective follow-up study involved all cases of MI-FTC operated at the Karolinska University Hospital between 1986 and 2009. Outcome was analysed using death from MI-FTC as endpoint. Fifty-eight patients (41 women and 17 men) with MI-FTC were identified. The median follow-up time was 140 (range 21-308) months. Vascular invasion was observed in 36 cases and was associated with larger tumour size [median 40 (20-76) compared with 24 (10-80) mm for patients with capsular invasion only (P = 0.001)] and older patients [54 (20-92) vs. 44 (11-77) years; P = 0.019]. Patients with vascular invasion were more often treated with thyroidectomy (21/36 compared to 7/22 with capsular invasion only; P = 0.045). Five patients died from metastatic disease of FTC after a median follow-up of 114 (range 41-193) months; all were older than 50 years (51-72) at the time of the initial surgery; vascular invasion was present in all tumours and all but one were treated with thyroidectomy. Univariate analysis identified combined capsular and vascular invasion (P = 0.034), age at surgery ≥50 years (P = 0.023) and male gender (P = 0.005) as related to risk of death from MI-FTC. MI-FTC should not be considered a purely indolent disease. Age at diagnosis and the existence of combined capsular and vascular invasion were identified as important prognostic factors.

    Full Text Available Abstract Background Selection of early stage non-small cell lung cancer patients with a high risk of recurrence is warranted in order to select patients who will benefit from adjuvant treatment strategies. We evaluated the prognostic value of integrin expression profiles in a retrospective study on frozen primary tumors of 68 patients with early stage non-small cell lung cancer. Methods A retrospective study was performed on frozen primary tumors of 68 early stage non-small cell lung cancer patients with a follow up of at least 10 years. From all tumor tissues, RNA was isolated and reverse transcribed into cDNA. qPCR was used to generate mRNA expression profiles including integrins alpha1, 2, 3, 4, 5, 6, 7, 11, and V as well as integrins beta1, 3, 4, 5, 6, and 8. Results The expression levels of integrins alpha5, beta1 and beta3 predicted overall survival and disease free survival in early stage NSCLC patients. There was no association between integrin expression and lymph node metastases. Comparison between the histological subtypes revealed a distinct integrin signature for squamous cell carcinoma while the profiles of adenocarcinoma and large cell carcinoma were largely the same. Conclusion Integrin expression in NSCLC is important for the development and behavior of the tumor and influences the survival of the patient. Determining the integrin expression profile might serve as a tool in predicting the prognosis of individual patients.

    Purpose To define characteristics, treatment response, and outcomes of men with brain metastases (BM) from germ cell tumors (GCT). Patients and Methods Data from 523 men with BM from GCT were collected retrospectively from 46 centers in 13 countries by using standardized questionnaires. Clinical features were correlated with overall survival (OS) as the primary end point. Results BM were present at initial diagnosis in 228 men (group A) and at relapse in 295 men (group B). OS at 3 years (3-year OS) was superior in group A versus group B (48% v 27%; P < .001). Multiple BM and the presence of liver or bone metastasis were independent adverse prognostic factors in both groups; primary mediastinal nonseminoma (group A) and elevations of α-fetoprotein of 100 ng/mL or greater or of human chorionic gonadotropin of 5,000 U/L or greater (group B) were additional independent adverse prognostic factors. Depending on these factors, the 3-year OS ranged from 0% to 70% in group A and from 6% to 52% in group B. In group A, 99% of patients received chemotherapy; multimodality treatment or high-dose chemotherapy was not associated with statistically improved survival in multivariable analysis. In group B, only 54% of patients received chemotherapy; multimodality treatment was associated with improved survival compared with single-modality therapy (hazard ratio, 0.51; 95% CI, 0.36 to 0.73; P < .001), as was high-dose compared with conventional-dose chemotherapy (hazard ratio, 0.41; 95% CI, 0.24 to 0.70; P = .001). Conclusion Men with BM from GCT have poor OS, particularly if additional risk factors are present. High-dose chemotherapy and multimodality treatment seemed to improve survival probabilities in men with BM at relapse. PMID:26460295

    Cervical cancer remains one of the most common malignancies in women. Previous study proved MMP-9 might be prognostic marker for multiple human malignancies. The present study was to investigate the protein expression of MMP-9 in cervical cancer and its association with clinicopathological characteristics as well as prognosis of patients. Cervical cancer specimens from 225 cases who had not received chemotherapy or radiotherapy prior to surgery were collected. Immunochemistry assays were utilized to investigate MMP-9 protein expression. Results showed that MMP-9 expression was increased in cervical cancer and associated with stromal invasion, FIGO stage, lymph node metastasis, and vascular invasion. Kaplan-Meier analysis showed that patients with cervical cancer of positive MMP-9 staining tend to have worse overall survival. In multivariate analysis stratified for known prognostic variables, MMP-9 was proved to be an independent prognostic factor. The present study confirmed that MMP-9 expression in cervical cancer was an independent prognostic factor of patients, which might be a potential diagnostic and even therapeutic target of cervical cancer.

    Full Text Available Lung cancer accounts for the majority of cancer-related deaths worldwide of which non-small-cell lung carcinoma alone takes a toll of around 85%. Platinum-based therapy is the stronghold for lung cancer at present. The discovery of various molecular alterations that underlie lung cancer has contributed to the development of specifically targeted therapies employing specific mutation inhibitors. Targeted chemotherapy based on molecular profiling has shown great promise in lung cancer treatment. Various molecular markers with predictive and prognostic significance in lung cancer have evolved as a result of advanced research. Testing of EGFR and Kras mutations is now a common practice among community oncologists, and more recently, ALK rearrangements have been added to this group. This paper discusses various predictive and prognostic markers that are being investigated and have shown significant relevance which can be exploited for targeted treatment in lung cancer.

    Full Text Available Abstract Background Multiple breast cancer gene expression profiles have been developed that appear to provide similar abilities to predict outcome and may outperform clinical-pathologic criteria; however, the extent to which seemingly disparate profiles provide additive prognostic information is not known, nor do we know whether prognostic profiles perform equally across clinically defined breast cancer subtypes. We evaluated whether combining the prognostic powers of standard breast cancer clinical variables with a large set of gene expression signatures could improve on our ability to predict patient outcomes. Methods Using clinical-pathological variables and a collection of 323 gene expression "modules", including 115 previously published signatures, we build multivariate Cox proportional hazards models using a dataset of 550 node-negative systemically untreated breast cancer patients. Models predictive of pathological complete response (pCR to neoadjuvant chemotherapy were also built using this approach. Results We identified statistically significant prognostic models for relapse-free survival (RFS at 7 years for the entire population, and for the subgroups of patients with ER-positive, or Luminal tumors. Furthermore, we found that combined models that included both clinical and genomic parameters improved prognostication compared with models with either clinical or genomic variables alone. Finally, we were able to build statistically significant combined models for pathological complete response (pCR predictions for the entire population. Conclusions Integration of gene expression signatures and clinical-pathological factors is an improved method over either variable type alone. Highly prognostic models could be created when using all patients, and for the subset of patients with lymph node-negative and ER-positive breast cancers. Other variables beyond gene expression and clinical-pathological variables, like gene mutation status or DNA

  20. High-grade acute organ toxicity as positive prognostic factor in primary radio(chemo)therapy for locally advanced, inoperable head and neck cancer

    International Nuclear Information System (INIS)

    Purpose: to test for a possible correlation between high-grade acute organ toxicity during primary radio(chemo)therapy and treatment outcome in patients with locally advanced head and neck squamous cell carcinoma (HNSCC). Patients and methods: from 05/1994 to 01/2009, 216 HNSCC patients were treated with radio(chemo)therapy in primary approach. They received normofractionated (2 Gy/fraction) irradiation including associated nodal drainage sites to a cumulative dose of 70 Gy. 151 patients received additional concomitant chemotherapy (111 patients 5-fluorouracil/mitomycin C, 40 patients cisplatin-based). Toxicity during treatment was monitored weekly according to the Common Toxicity Criteria (CTC), and any toxicity grade CTC ≥ 3 of mucositis, dysphagia or skin reaction was assessed as high-grade acute organ toxicity for later analysis. Results: a statistically significant coherency between high-grade acute organ toxicity and overall survival as well as locoregional control was found: patients with CTC ≥ 3 acute organ toxicity had a 5-year overall survival rate of 4% compared to 8% in patients without (p < 0.01). Thereby, multivariate analyses revealed that the correlation was independent of other possible prognostic factors or factors that may influence treatment toxicity, especially concomitant chemotherapy and radiotherapy technique or treatment-planning procedure. Conclusion: these data indicate that normal tissue and tumor tissue may behave similarly with respect to treatment response, as high-grade acute organ toxicity during radio(chemo)therapy showed to be an independent prognostic marker in the own patient population. However, the authors are aware of the fact that a multivariate analysis in a retrospective study generally has statistical limitations. Therefore, their hypothesis should be further analyzed on biomolecular and clinical levels and other tumor entities in prospective trials. (orig.)

  1. Loss of aquaporin 3 protein expression constitutes an independent prognostic factor for progression-free survival: an immunohistochemical study on stage pT1 urothelial bladder cancer

    International Nuclear Information System (INIS)

    Treatment of patients with stage pT1 urothelial bladder cancer (UBC) continues to be a challenge due to its unpredictable clinical course. Reliable molecular markers that help to determine appropriate individual treatment are still lacking. Loss of aquaporin (AQP) 3 protein expression has previously been shown in muscle-invasive UBC. The aim of the present study was to investigate the prognostic value of AQP3 protein expression with regard to the prognosis of stage pT1 UBC. AQP 3 protein expression was investigated by immunohistochemistry in specimens of 87 stage T1 UBC patients, who were diagnosed by transurethral resection of the bladder (TURB) and subsequent second resection at a high-volume urological centre between 2002 and 2009. Patients underwent adjuvant instillation therapy with Bacillus Calmette-Guérin (BCG). Loss of AQP3 protein expression was defined as complete absence of the protein within the whole tumour. Expression status was correlated retrospectively with clinicopathological and follow-up data (median: 31 months). Multivariate Cox regression analysis was used to assess the value of AQP3 tumour expression with regard to recurrence-free (RFS), progression-free (PFS) and cancer-specific survival (CSS). RFS, PFS and CSS were calculated by Kaplan-Meier analysis and Log rank test. 59% of patients were shown to exhibit AQP3-positive tumours, whereas 41% of tumours did not express the marker. Loss of AQP3 protein expression was associated with a statistically significantly worse PFS (20% vs. 72%, p=0.020). This finding was confirmed by multivariate Cox regression analysis (HR 7.58, CI 1.29 – 44.68; p=0.025). Loss of AQP3 protein expression in pT1 UBC appears to play a key role in disease progression and is associated with worse PFS. Considering its potential prognostic value, assessment of AQP3 protein expression could be used to help stratify the behavior of patients with pT1 UBC

    Objective: To investigate the prognostic factors for stage Ⅳ non-small cell lung cancer (NSCLC) with distant metastasis and establish a reliable model of clinical prognostic index.Methods: From January 1990 to April 2005,313 primary NSCLC patients with metastasis,who had been treated in Shanghai Chest Hospital,were reviewed.Survival time was estimated according to the Kaplan-Meier method.Cox proportional hazard regression model was used for multivariate analysis.Results: Among the 313 cases of non-small cell lung cancer (NSCLC) at stage Ⅳ,there were 218 and 95 patients with metastasis to single and different organs,respectively.The overall median survival time for all 313 cases of NSCLC patients was 10.8 (9.00,12.30)months and the overall 1-,2-,3-,4- and 5-year survival rate was 45%,18%,12%,4% and 0%.There were 63,174,127,36,18,11 and 5 patients with metastasis to brain (20.13%),bone (55.59%),lung (40.58%),liver (11.50%),adrenal gland (5.75%),subcutaneous (3.51%) and others,respectively.The survival time was shortest in subcutaneous metastasis (4.6 months),and liver 7.0 months,brain 8.0 months,adrenal gland 8.6 months,bone 10.6 months,lung 11.8 months.Kaplan-Meier estimation showed that patients anatomic typing,KPS,numbers of organ with metastasis,appetite,liver,adrenal gland and subcutaneous metastasis,body weight loss,smoking,index of smoking,chemotherapy,cycles of chemotherapy were the predictors of survival.Multivariate analysis showed survival statistically significant correlation with anatomic typing,KPS,appetite,liver and subcutaneous metastasis,body weight loss,cycles of chemotherapy.The relative risk (RR) was 1.51,1.97,1.55,1.67,2.56,and 2.56 respectively.Conclusion: Survival time decreases distinctly in patients who had distant metastasis to more than two different organs (P<0.01).Bone is the commonest organ for distant metastasis in lung cancer.The prognosis is poor when lung cancer appears subcutaneous metastasis and liver metastasis

  3. Context-dependent interpretation of the prognostic value of BRAF and KRAS mutations in colorectal cancer

    International Nuclear Information System (INIS)

    The mutation status of the BRAF and KRAS genes has been proposed as prognostic biomarker in colorectal cancer. Of them, only the BRAF V600E mutation has been validated independently as prognostic for overall survival and survival after relapse, while the prognostic value of KRAS mutation is still unclear. We investigated the prognostic value of BRAF and KRAS mutations in various contexts defined by stratifications of the patient population. We retrospectively analyzed a cohort of patients with stage II and III colorectal cancer from the PETACC-3 clinical trial (N = 1,423), by assessing the prognostic value of the BRAF and KRAS mutations in subpopulations defined by all possible combinations of the following clinico-pathological variables: T stage, N stage, tumor site, tumor grade and microsatellite instability status. In each such subpopulation, the prognostic value was assessed by log rank test for three endpoints: overall survival, relapse-free survival, and survival after relapse. The significance level was set to 0.01 for Bonferroni-adjusted p-values, and a second threshold for a trend towards statistical significance was set at 0.05 for unadjusted p-values. The significance of the interactions was tested by Wald test, with significance level of 0.05. In stage II-III colorectal cancer, BRAF mutation was confirmed a marker of poor survival only in subpopulations involving microsatellite stable and left-sided tumors, with higher effects than in the whole population. There was no evidence for prognostic value in microsatellite instable or right-sided tumor groups. We found that BRAF was also prognostic for relapse-free survival in some subpopulations. We found no evidence that KRAS mutations had prognostic value, although a trend was observed in some stratifications. We also show evidence of heterogeneity in survival of patients with BRAF V600E mutation. The BRAF mutation represents an additional risk factor only in some subpopulations of colorectal cancers, in

    Full Text Available Axillary lymph node involvement is an important prognostic factor for breast cancer survival but is confounded by the number of nodes examined. We compare the performance of the log odds prognostic index (Lpi, using a ratio of the positive versus negative lymph nodes, with the Nottingham Prognostic Index (NPI for short-term breast cancer specific disease free survival. A total of 1818 operable breast cancer patients treated in the University Hospital of Leuven between 2000 and 2005 were included. The performance of the NPI and Lpi were compared on two levels: calibration and discrimination. The latter was evaluated using the concordance index (cindex, the number of patients in the extreme groups, and difference in event rates between these. The NPI had a significant higher cindex, but a significant lower percentage of patients in the extreme risk groups. After updating both indices, no significant differences between NPI and Lpi were noted.

    Full Text Available Nora I Schneider, Cord LangnerInstitute of Pathology, Medical University of Graz, Graz, AustriaAbstract: Tumor staging according to the American Joint Committee on Cancer/Union for International Cancer Control tumor, node, metastasis (TNM system is currently regarded as the standard for staging of patients with colorectal cancer. This system provides the strongest prognostic information for patients with early stage disease and those with advanced disease. For patients with intermediate levels of disease, it is less able to predict disease outcome. Therefore, additional prognostic markers are needed to improve the management of affected patients. Ideal markers are readily assessable on hematoxylin and eosin-stained tumor slides, and in this way are easily applicable worldwide. This review summarizes the histological features of colorectal cancer that can be used for prognostic stratification. Specifically, we refer to the different histological variants of colorectal cancer that have been identified, each of these variants carrying distinct prognostic significance. Established markers of adverse outcomes are lymphatic and venous invasion, as well as perineural invasion, but underreporting still occurs in the routine setting. Tumor budding and tumor necrosis are recent advances that may help to identify patients at high risk for recurrence. The prognostic significance of the antitumor inflammatory response has been known for quite a long time, but a lack of standardization prevented its application in routine pathology. However, scales to assess intra- and peritumoral inflammation have recently emerged, and can be expected to strengthen the prognostic significance of the pathology report.Keywords: colorectal cancer, lymphatic invasion, blood-vessel invasion, perineural invasion, tumor budding, tumor necrosis

  7. Anaplastic thyroid carcinoma: outcome and prognostic factors

    International Nuclear Information System (INIS)

    Purpose: Anaplastic carcinoma of the thyroid has been described as a rapidly progressive disease. We assessed the outcome and prognostic factors in patients with anaplastic thyroid carcinoma at our institution. Materials and Methods: Between 1975 and 1995, 37 patients were seen and treated at our institution with pathologically proven anaplastic carcinoma of the thyroid gland. Patients ranged in age from 49 to 97 years old (median 73 years) and females were represented in a 2:1 ratio. Many patients had history of prior benign thyroid disease (17) or low grade malignancy (6). Other medical illnesses were frequently present in these patients, including 5 with diabetes, 1 scleroderma, 1 sarcoidosis and 1 polycythemia vera. 12 patients had metastatic disease at presentation. 26 patients had locally advanced (T4) disease. The time from diagnosis to treatment was never longer than 1 month. Management was most often with biopsy only (22 patients) and local irradiation (34 patients, median dose 52.5 Gy). 15 patients had primary surgical resection, one of which had negative surgical margins. 11 patients received chemotherapy, 9 with Adriamycin-based regimens. Follow-up ranged from 4 months to 11 years, with a mean of 11 months. Results: 26 patients had a local response, either partial or complete, to their treatment regimen. However, systemic disease was an important cause of failure. 9 patients (24%) survived at least one year from diagnosis; 3 (8%) survived beyond two years. The development of metastases occurred quickly in originally localized disease, at a median of 2 months. Metastases occurred most commonly in the lung (11 of 14 cases), but also occured in brain (2), liver (1), bone (1) and pericardium (1). Performance status, sex, metastatic disease, hyperfractionation, treatment modalities, RT dose, age and response to treatment were assessed as prognostic factors for survival. On univariate analysis, age over 70 (p=.004) and failure to attain a complete response to

    There is growing consensus that multigene prognostic tests provide useful complementary information to tumor size and grade in estrogen receptor (ER)-positive breast cancers. The tests primarily rely on quantification of ER and proliferation-related genes and combine these into multivariate prediction models. Since ER-negative cancers tend to have higher proliferation rates, the prognostic value of current multigene tests in these cancers is limited. First-generation prognostic signatures (Oncotype DX, MammaPrint, Genomic Grade Index) are substantially more accurate to predict recurrence within the first 5 years than in later years. This has become a limitation with the availability of effective extended adjuvant endocrine therapies. Newer tests (Prosigna, EndoPredict, Breast Cancer Index) appear to possess better prognostic value for late recurrences while also remaining predictive of early relapse. Some clinical prediction problems are more difficult to solve than others: there are no clinically useful prognostic signatures for ER-negative cancers, and drug-specific treatment response predictors also remain elusive. Emerging areas of research involve the development of immune gene signatures that carry modest but significant prognostic value independent of proliferation and ER status and represent candidate predictive markers for immune-targeted therapies. Overall metrics of tumor heterogeneity and genome integrity (for example, homologue recombination deficiency score) are emerging as potential new predictive markers for platinum agents. The recent expansion of high-throughput technology platforms including low-cost sequencing of circulating and tumor-derived DNA and RNA and rapid reliable quantification of microRNA offers new opportunities to build extended prediction models across multiplatform data.

    CD133 and cancer-testis antigens (CTAs) may be potential predicted markers of adjuvant chemotherapy or immune therapy, and they may be the independent prognostic factor of NSCLC. Nowadays, there is still no predictive biomarker identified for the use of adjuvant chemotherapy in non-small cell lung cancer (NSCLC) patients. To clarify the role of CD133 and CTAs as a predictive marker for adjuvant chemotherapy or prognostic factors of overall survival, we performed a retrospective study in 159 s...

  11. Prognostic value of lymph node ratio in node-positive breast cancer in Egyptian patients

    International Nuclear Information System (INIS)

    Background: Breast cancer in Egypt is the most common cancer among women and is the leading cause of cancer mortality. Traditionally, axillary lymph node involvement is considered among the most important prognostic factors in breast cancer. Nonetheless, accumulating evidence suggests that axillary lymph node ratio should be considered as an alternative to classical pN classification. Materials and methods: We performed a retrospective analysis of patients with operable node positive breast cancer, to investigate the prognostic significance of axillary lymph node ratio. Results: Five-hundred patients were considered eligible for the analysis. Median follow-up was 35 months (95% Cl 32-37 months), the median disease-free survival (DFS) was 49 months (95% Cl, 46.4-52.2 months). The classification of patients based on pN staging system failed to prognosticate DFS in the multivariate analysis. Conversely, grade 3 tumors, and the intermediate (> 0.20 to <0.65) and high (>0.65) LNR were the only variables that were independently associated with adverse DFS. The overall survival (OS) in this series was 69 months (95% Cl 60-77). Conclusion: The analysis of outcome of patients with early breast cancer in Egypt identified the adverse prognostic effects of high tumor grade, ER negativity and intermediate and high LNR on DFS. If the utility of the LNR is validated in other studies, it may replace the use of absolute number of axillary lymph nodes.

    Full Text Available Background and objective Brain metastasis (BM is often found in the patients with lung cancer. Radiotherapy is regular and effective means of therapy and it aims at palliating symptoms and prolonging survival time. However, now there are different viewpoints on protocols of radiotherapy and prognostic factors. A retrospective analysis is used to evaluate the results of treatment for 82 cases with brain metastasis from non-small cell lung cancer (NSCLC and explore the prognostic factors to establish a prognostic index (PI model. Methods From Feb.1995 to Oct. 2006, 82 patients irradiated for BM from NSCLC, with both complete medical charts and follow-up data available, were eligible for this retrospective analysis. A number of potential factors which might affect prognosis after irradiation were evaluated. The significance of prognostic variables in the survival resulted from both univariate analysis by Kaplan-Meier combining with log-rank test and multivariate Cox regression model. The prognostic index (PI was established based on Cox regression analysis and subgrouping values. Results The follow-up time was 1-120 months. For the entire cohort, the median survival from the start of radiation for BM was 10.5 months, and the actuarial overall survival rate was 50.8%, 23.7% and 5.1% at 0.5, 1 and 2 years respectively. Univariate analysis showed KPS, control of primary tumor, interval from the beginning of diagnostic to BM, extracranial systemic metastasis, counts of lymphocyte and solitary BM were predictors of prognosis. However, in the Cox multivariate analysis, only KPS, control of primary tumor, interval from the beginning of diagnostic to BM and solitary BM were significant prognostic factors. The prognostic index was established based on Cox regression analysis and 82 patients were stratified good, intermediate and poor prognostic sub-groups. The difference of survival rate among 3 subgroups is significant (P<0.001. Conclusion Radiotherapy is

    Full Text Available The functions of non-coding microRNAs (miRNAs in tumorigenesis are just beginning to emerge. Previous studies from our laboratory have identifi ed a number of miRNAs that were deregulated in colon cancer cell lines due to the deletion of the p53 tumor suppressor gene. In this study, the in vivo signifi cance of some of these miRNAs was further evaluated using colorectal clinical samples. Ten miRNAs (hsa-let-7b, hsa-let-7g, hsa-miR-15b, hsa-miR-181b, hsa-miR-191, hsa-miR-200c, hsa-miR-26a, hsa-miR-27a, hsa-miR-30a-5p and hsa-miR-30c were evaluated for their potential prognostic value in colorectal cancer patients. Forty eight snap frozen clinical colorectal samples (24 colorectal cancer and 24 paired normal patient samples with detailed clinical follow-up information were selected . The expression levels of 10 miRNAs were quantified via qRT-PCR analysis. The statistical signifi cance of these markers for disease prognosis was evaluated using a two tailed paired Wilcoxon test. A Kaplan-Meier survival curve was generated followed by performing a Logrank test. Among the ten miRNAs, hsa-miR-15b (p = 0.0278, hsa-miR-181b (p = 0.0002, hsa-miR-191 (p = 0.0264 and hsa-miR-200c (p = 0.0017 were signifi cantly over-expressed in tumors compared to normal colorectal samples. Kaplan-Meier survival analysis indicated that hsa-miR-200c was signifi cantly associated with patient survival (p = 0.0122. The patients (n = 15 with higher hsa-miR-200c expression had a shorter survival time (median survival = 26 months compared to patients (n = 9 with lower expression (median survival = 38 months. Sequencing analysis revealed that hsa-miR-181b (p = 0.0098 and hsa-miR-200c (p = 0.0322 expression were strongly associated with the mutation status of the p53 tumor suppressor gene. Some of these miRNAs may function as oncogenes due to their over-expression in tumors. hsa-miR-200c may be a potential novel prognostic factor in colorectal cancer.

    The prognostic influence of circumferential resection margin (CRM) status in extraperitoneal rectal cancer probably differs from that of intraperitoneal rectal cancer because of its different anatomical and biological behaviors. However, previous reports have not provided the data focused on extraperitoneal rectal cancer. Therefore, the aim of this study was to examine the prognostic significance of the CRM status in patients with extraperitoneal rectal cancer. From January 2005 to December 2008, 248 patients were treated for extraperitoneal rectal cancer and enrolled in a prospectively collected database. Extraperitoneal rectal cancer was defined based on tumors located below the anterior peritoneal reflection, as determined intraoperatively by a surgeon. Cox model was used for multivariate analysis to examine risk factors of recurrence and mortality in the 248 patients, and multivariate logistic regression analysis was performed to identify predictors of recurrence and mortality in 135 patients with T3 rectal cancer. CRM involvement for extraperitoneal rectal cancer was present in 29 (11.7%) of the 248 patients, and was the identified predictor of local recurrence, overall recurrence, and death by multivariate Cox analysis. In the 135 patients with T3 cancer, CRM involvement was found to be associated with higher probability of local recurrence and mortality. In extraperitoneal rectal cancer, CRM involvement is an independent risk factor of recurrence and survival. Based on the results of the present study, it seems that CRM involvement in extraperitoneal rectal cancer is considered an indicator for (neo)adjuvant therapy rather than conventional TN status.

Extraperitoneal rectal cancer was defined based on tumors located below the anterior peritoneal reflection, as determined intraoperatively by a surgeon. Cox model was used for multivariate analysis to examine risk factors of recurrence and mortality in the 248 patients, and multivariate logistic regression analysis was performed to identify predictors of recurrence and mortality in 135 patients with T3 rectal cancer. CRM involvement for extraperitoneal rectal cancer was present in 29 (11.7%) of the 248 patients, and was the identified predictor of local recurrence, overall recurrence, and death by multivariate Cox analysis. In the 135 patients with T3 cancer, CRM involvement was found to be associated with higher probability of local recurrence and mortality. In extraperitoneal rectal cancer, CRM involvement is an independent risk factor of recurrence and survival. Based on the results of the present study, it seems that CRM involvement in extraperitoneal rectal cancer is considered an indicator for (neo)adjuvant therapy rather than conventional TN status.

    To study the prognostic effect of bcl-2 oncogene and its gene family members bax, bcl-x expression in breast cancer patients. Methods: expression of bcl-2, bax proteins in 91 human breast cancer tissue sections were studied by immunohistochemical method. Bcl-x1 mRNA expression in frozen tissues from 16 breast cancer patients were detected using Northern blot method. Results: bcl-2 protein positivity was found in 60/91 (65.9%) patients, and bax positivity 59/91 (64.8%). Bcl-2 and bax expression levels were associated with apoptotic index(AI), histological grade, axillary lymph node metastasis, postoperative local recurrence and metastasis. Bcl-2 expression was related to ER positivity. In univariate analysis for disease free survival (DFS), bcl-2 and bax protein levels, and Al were all found to have prognostic value. The result of Cox's model multivariate analysis showed that bcl-2 protein level was an independent prognostic factor. In 16 frozen breast cancer tissues, 8/16(50%) had higher level of bcl-x1 mRNA, which showed correlation with bcl-2 protein expression and axillary lymph node metastasis. Conclusion: The findings indicate that dysregulated expressions of bcl-2, bax and bcl-x1 apoptosis-related genes, suggestive of serious deregulation of apoptotic process, may contribute to the biologic aggressiveness of breast cancer. Bcl-2 protein is an independent indicator of prognosis in breast cancer patients.

    Re-programming of lipogenic signaling has been previously demonstrated to result in significant alterations in tumor cell pathology. Sterol regulatory element-binding protein 1 (SREBP-1) is a known transcription factor of lipogenic genes. Despite the fact that its functions in proliferation and apoptosis have been elucidated in recent studies, its role in tumor cell migration and invasion, particularly in breast cancer, remains unclear. In present study, the messenger RNA and protein expression levels of SREBP-1 in cancer tissues were observed to be overexpressed compared with those in matched para-cancerous tissues (Pmigration and invasion (Pmigration and invasion, and may serve as a prognostic marker of this malignancy.

    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

    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.

    The aim of this study was to evaluate the significance of the Ki67 labeling index and p53 status as prognostic and predictive indicators of operable estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Among 697 consecutive patients with primary breast cancer who underwent curative surgery between 2002 and 2013, 308 patients with ER-positive and HER2-negative breast cancer were assessed. The results of the multivariate Cox analysis demonstrated that a high Ki67 labeling index was significantly associated with a short recurrence-free interval (RFI) (p=0.004) and was marginally associated with a worse overall survival (p=0.074). A positive p53 status was not associated with worse outcomes. To validate the cut-off values of the Ki67 labeling index for identifying patients who may benefit from additional chemotherapy, prognostic factors were investigated in breast cancer patients treated postoperatively with endocrine therapy alone. Analysis of receiver operating characteristic curves demonstrated that a Ki67 labeling index cut-off of 20.0% was optimal for predicting recurrence among patients who did not receive adjuvant chemotherapy. The 5-year RFIs for patients with Ki67 <20 and ≥20% were 97.2 and 86.6%, respectively (p=0.0244). A high Ki67 labeling index (≥20%) was significantly associated with large tumors (p<0.01), lymph node metastasis (p=0.0236) and positive p53 status (p<0.001). The univariate analysis demonstrated that Ki67 labeling index ≥20%, lymph node metastasis and progesterone receptor negativity were significant worse prognostic factors for RFI (p=0.0333, 0.0116 and 0.0573, respectively). The Ki67 labeling index was found to be a useful prognostic factor in patients with ER-positive and HER2-negative breast cancer and the cut-off values of the Ki67 labeling index for making a decision regarding adjuvant treatment were validated.

  18. Patient-specific data fusion defines prognostic cancer subtypes.

    2011-10-01

    Full Text Available Different data types can offer complementary perspectives on the same biological phenomenon. In cancer studies, for example, data on copy number alterations indicate losses and amplifications of genomic regions in tumours, while transcriptomic data point to the impact of genomic and environmental events on the internal wiring of the cell. Fusing different data provides a more comprehensive model of the cancer cell than that offered by any single type. However, biological signals in different patients exhibit diverse degrees of concordance due to cancer heterogeneity and inherent noise in the measurements. This is a particularly important issue in cancer subtype discovery, where personalised strategies to guide therapy are of vital importance. We present a nonparametric Bayesian model for discovering prognostic cancer subtypes by integrating gene expression and copy number variation data. Our model is constructed from a hierarchy of Dirichlet Processes and addresses three key challenges in data fusion: (i To separate concordant from discordant signals, (ii to select informative features, (iii to estimate the number of disease subtypes. Concordance of signals is assessed individually for each patient, giving us an additional level of insight into the underlying disease structure. We exemplify the power of our model in prostate cancer and breast cancer and show that it outperforms competing methods. In the prostate cancer data, we identify an entirely new subtype with extremely poor survival outcome and show how other analyses fail to detect it. In the breast cancer data, we find subtypes with superior prognostic value by using the concordant results. These discoveries were crucially dependent on our model's ability to distinguish concordant and discordant signals within each patient sample, and would otherwise have been missed. We therefore demonstrate the importance of taking a patient-specific approach, using highly-flexible nonparametric

    Hedgehog signaling pathway plays an important role in normal mammalian gastrointestinal development and is implicated in the oncogenesis of various tumors. However, its correlation with progression and prognosis of colon cancer has not been well documented. This study was designed to investigate expression patterns of related proteins in hedgehog signaling pathway in colon cancer to elucidate its prognostic value in this tumor. Using human colon cancer and their corresponding non-diseased colon from 228 patients' biopsies, the expression of sonic hedgehog, its receptor Patched, and downstream transcription factor Gli1 was investigated by immunohistochemical staining to assess their association with the clinicopathological characteristics of colon cancer. Disease-free survival and overall survival were examined by Kaplan-Meier estimates and the log-rank test. Prognostic factors were determined by multivariate Cox analysis. One hundred and thirty-eight patients (59.6%) had sonic hedgehog-positive tumors and that the disease-free survival (43.5 vs. 73.3%, P colon cancer (50.0 vs. 89.3%, P colon cancer. This is the first report describing about the relationship between hedgehog signaling pathway and the prognosis of colon cancer.

  2. An analysis of clinical and treatment related prognostic factors on outcome using biochemical control as an end-point in patients with prostate cancer treated with external beam irradiation

    International Nuclear Information System (INIS)

    Purpose: We reviewed our institution's experience in treating patients with clinically localized prostate cancer with external beam irradiation (RT) to determine if previously analyzed clinical and treatment related prognostic factors affected outcome when biochemical control was used as an end-point to evaluate results. Materials and methods: Between 1 January 1987 and 31 December 1991, 470 patients with clinically localized prostate cancer were treated with external beam RT using localized prostate fields at William Beaumont Hospital. Biochemical control was defined as PSA nadir ≤1.5 ng/ml within 1 year of treatment. After achieving nadir, if two consecutive increases of PSA were noted, the patient was scored a failure at the time of the first increase. Prognostic factors, including the total number of days in treatment, the method of diagnosis, a history of any pretreatment transurethral resection of the prostate (TURP) and the type of boost were analyzed. Results: Median follow-up was 48 months. No statistically significant difference in rates of biochemical control were noted for treatment time, overall time (date of biopsy to completion of RT), history of any pretreatment TURP, history of diagnosis by TURP, or boost techniques. Patients diagnosed by TURP had a significant improvement in the overall rate of biochemical control (P < 0.03) compared to transrectal/transperineal biopsy. The 5-year actuarial rates were 58 versus 39%, respectively. This improvement was not evident when pretreatment PSA, T stage, or Gleason score were controlled for. On multivariate analysis, no variable was associated with outcome. When analysis was limited to a more favorable group of patients (T1/T2 tumors, pretreatment PSA ≤20 ng/ml and Gleason score <7), none of these variables were significantly predictive of biochemical control when controlling for pretreatment PSA, T stage and Gleason score. Conclusions: No significant effect of treatment time, overall time, pretreatment

    Mihriban Karaayvaz

    Full Text Available PURPOSE: microRNAs have emerged as key regulators of gene expression, and their altered expression has been associated with tumorigenesis and tumor progression. Thus, microRNAs have potential as both cancer biomarkers and/or potential novel therapeutic targets. Although accumulating evidence suggests the role of aberrant microRNA expression in endometrial carcinogenesis, there are still limited data available about the prognostic significance of microRNAs in endometrial cancer. The goal of this study is to investigate the prognostic value of selected key microRNAs in endometrial cancer by the analysis of archival formalin-fixed paraffin-embedded tissues. EXPERIMENTAL DESIGN: Total RNAs were extracted from 48 paired normal and endometrial tumor specimens using Trizol based approach. The expression of miR-26a, let-7g, miR-21, miR-181b, miR-200c, miR-192, miR-215, miR-200c, and miR-205 were quantified by real time qRT-PCR expression analysis. Targets of the differentially expressed miRNAs were quantified using immunohistochemistry. Statistical analysis was performed by GraphPad Prism 5.0. RESULTS: The expression levels of miR-200c (P<0.0001 and miR-205 (P<0.0001 were significantly increased in endometrial tumors compared to normal tissues. Kaplan-Meier survival analysis revealed that high levels of miR-205 expression were associated with poor patient overall survival (hazard ratio, 0.377; Logrank test, P = 0.028. Furthermore, decreased expression of a miR-205 target PTEN was detected in endometrial cancer tissues compared to normal tissues. CONCLUSION: miR-205 holds a unique potential as a prognostic biomarker in endometrial cancer.

    The purpose of this study is to determine prognostic factors in patients with high-grade recurrent glioma for 3 outcome variables (overall survival, progression-free survival [PFS], and PFS rate 6 months after study registration [PFS6]). Data from 15 North Central Cancer Treatment Group (NCCTG) trials (n = 469, 1980–2004) and 12 North American Brain Tumor Consortium (NABTC) trials (n = 596, 1998–2002) were included. Eighteen prognostic variables were considered including type of treatment center (community/academic) and initial low-grade histology (yes/no). Recursive partitioning analysis (RPA), Cox proportional hazards, and logistic regression models with bootstrap resampling were used to identify prognostic variables. Longer survival was associated with last known grade (Grade) of III, younger age, ECOG performance score (PS) of 0, shorter time from initial diagnosis (DxTime), and no baseline steroid use. Factors associated with longer PFS were Grade III and shorter DxTime. For patients without temozolomide as part of the treatment regimen, the only factor associated with better PFS6 was Grade III, although DxTime was important in RPA and PS was important in logistic regression. Grade was the most important prognostic factor for all three endpoints regardless of the statistical method used. Other important variables for one or more endpoints included age, PS, and DxTime. Neither type of treatment center nor initial low-grade histology was identified as a major predictor for any endpoint. PMID:20150383

    Background/Aims: This study aimed to examine whether UHRF-1 and p53 overexpression is a prognostic marker for gastric cancer. Patients and Methods: Sixty-four patients with gastric cancer (study group) and 23 patients with gastritis (control group) were evaluated. Immunohistochemistry was used to examine expression of UHRF-1 and p53 in gastric cancers and a control group diagnosed with gastritis. Results: The median age was 63 years (18-83 years) in the study group. UHRF-1 was positive in 15 (23%) patients with gastric cancer and five (21.7%) patients with gastritis (P = 0.559). UHRF1 expression level in gastric cancer is more powerful than in gastritis (P = 0.046). Thirty-seven (61%) patients with gastric cancer and only one patient with gastritis were p53 positive (P < 0.001). After a median follow-up of 12 months (1–110), the 2-year overall survival rates were 55% and 30% in negative and positive p53, respectively (P = 0.084). Also, the 2-year overall survival rates were 45% and 53% in negative and positive UHRF-1, respectively (P = 0.132). Conclusion: According to this study, UHRF-1and p53 were not prognostic factors for gastric cancer, whereas they may have a diagnostic value for differantiating between gastric cancer and gastritis.

  7. Expression profile and prognostic role of sex hormone receptors in gastric cancer

    International Nuclear Information System (INIS)

    Increasing interest has been devoted to the expression and possible role of sex hormone receptors in gastric cancer, but most of these findings are controversial. In the present study, the expression profile of sex hormone receptors in gastric cancer and their clinicopathological and prognostic value were determined in a large Chinese cohort. The mRNA and protein expression of estrogen receptor alpha (ERα), estrogen receptor beta (ERβ), progesterone receptor (PR), and androgen receptor (AR) in primary gastric tumors and corresponding adjacent normal tissues from 60 and 866 Chinese gastric cancer patients was detected by real-time quantitative PCR and immunohistochemistry method, respectively. The expression profile of the four receptors was compared and their associations with clinicopathological characteristics were assessed by using Chi-square test. The prognostic value of the four receptors in gastric cancer was evaluated by using univariate and multivariate Cox regression analysis. The presence of ERα, ERβ, PR, and AR in both gastric tumors and normal tissues was confirmed but their expression levels were extremely low except for the predominance of ERβ. The four receptors were expressed independently and showed a decreased expression pattern in gastric tumors compared to adjacent normal tissues. The positive expression of the four receptors all correlated with high tumor grade and intestinal type, and ERα and AR were also associated with early TNM stage and thereby a favorable outcome. However, ERα and AR were not independent prognostic factors for gastric cancer when multivariate survival analysis was performed. Our findings indicate that the sex hormone receptors may be partly involved in gastric carcinogenesis but their clinicopathological and prognostic significance in gastric cancer appears to be limited

    The antigens of the ABO system are expressed on red blood cell membranes as well as on the surface of several other normal and pathological cells and tissues. Following the first clinical observations more than 60 years ago, the role of ABO blood group in cancer biology has been intensely studied by several investigators, and it is now widely recognised that ABO antigens are associated with the risk of developing several types of tumours, namely pancreatic and gastric cancers. However, whether this association also affects the clinical outcome of cancer patients is less certain. In this narrative review, based on literature data, we discuss the role of ABO blood types as prognostic biomarkers in different types of cancers. The current knowledge of the underlying pathogenic mechanisms of the association is also analysed. PMID:26674825

    Full Text Available Abstract Background Lymphoid infiltration is a prognostic marker in solid tumors, such as colorectal, breast and lung carcinomas. However, lymphoid infiltration is heterogeneous and the reproducibility of quantification based on single counts within a tumor is very low. We aimed to develop a reproducible method for evaluating lymphoid infiltration in tumors. Methods Virtual slides were obtained from tissue sections from the localized colorectal carcinomas of 117 patients, stained for CD3 and CD45R0. We assessed the variation of lymphoid cell density by automatic counts in 1 mm-wide, 5 μm-long segments of the invasive front, along an axis 4 mm in length running perpendicular to the invasive front of the tumor. Results We plotted curves of the variation of lymphocyte density across the tumor front. Three distinct patterns emerged from this linear quantification of lymphocyte (LQLI. In pattern 1, there was a high density of lymphocytes within the tumor. In pattern 2, lymphocyte density peaked close to the invasive margin. In pattern 3, lymphocytes were diffusely distributed, at low density. It was possible to classify all the tumors studied, and interobserver reproducibility was excellent (kappa =0.9. By contrast, single counts of CD3+ cells on tissue microarrays were highly variable for a given LQLI pattern, confirming the heterogeneity of lymphoid infiltration within individual tumors. In univariate analysis, all pathologic features (stage, metastatic lymph node ratio (LNR, vascular embolism, perineural invasion, CD3+ cell density, LQLI patterns for CD3+ and CD45R0+ cells were found to have a significant effect on disease-free survival (DFS. In multivariate analysis, only the LQLI pattern for CD3+ cells (HR: 6.02; 95% CI: 2.74-13.18 and metastatic lymph node ratio (HR: 6.14; 95% CI: 2.32-16.2 were associated with DFS. Conclusion LQLI is an automated, reproducible method for the assessment of lymphoid infiltration. However, validation of its

    Since diagnosis at an early stage still remains a key issue for modern oncology and is crucial for successful cancer therapy, development of sensitive, specific, and non-invasive tumor markers, especially, in serum, is urgently needed. Midkine (MK), a plasma secreted protein, was initially identified in embryonal carcinoma cells at early stages of retinoic acid-induced differentiation. Multiple studies have reported that MK plays important roles in tumor progression, and is highly expressed in various malignant tumors. Because increased serum MK concentrations also have been reported in patients with various tumors, serum MK may have the potential to become a very useful tumor marker. Here, we review and discuss the possibility and usefulness of MK as a novel tumor marker.

    Full Text Available Background: The brain is a rare site of metastases from ovarian cancer. Limited data are available on prognostic factors, standard treatment, and survival. Knowledge of clinical prognostic factors would help the management of patients with brain metastases. The aim of this study is to evaluate the impact of clinical factors and treatment modalities on survival in patients with brain metastases from ovarian cancer. Methods: We performed a retrospective analysis of an electronic database of patients with brain metastases from ovarian primary treated at Clatterbridge Centre for Oncology. Results: A total of 20 patients with brain metastases from an ovarian primary were treated from April 2001-February 2011. Median age at occurrence of brain metastases was 55 years. The median time from primary diagnosis to occurrence of brain metastases was 23 months. Median overall survival from diagnosis of brain metastases was 9 months. Poor ECOG performance status, platinum resistance, andadvanced FIGO staging were the most significant adverse variables identified. Median survival was 13 months for platinum sensitive patients and 6 months for platinum resistant patients. Conclusion: Platinum sensitivity is an important prognostic factor in patients with brain metastases from an ovarian primary tumor. Multimodal therapy that consists of surgery, radiotherapy, and chemotherapy should be considered where feasible.

    Full Text Available Background: To assess the prognosis of surgical neonates at admission and the factors responsible for mortality in neonates.Material and Methods: A prospective study was conducted in a tertiary level hospital over 15 months and various clinical and biochemical parameters were collected and analyzed using STATA® and SPSS®.Results: On multivariate analysis of 165 neonates, early gestational age, respiratory distress and shock at presentation were the factors of poor prognosis in neonates. The factors could be related to poor antenatal care and sepsis acquired before transfer of the baby to the nursery. Conclusion: The improvement in antenatal care and asepsis during transfer and handling the babies is of utmost importance to improve the prognosis of surgical neonates.

  14. Prospective evaluation of prognostic factors uPA/PAI-1 in node-negative breast cancer: Phase III NNBC3-Europe trial (AGO, GBG, EORTC-PBG) comparing 6 × FEC versus 3 × FEC/3 × Docetaxel

    International Nuclear Information System (INIS)

    Today, more than 70% of patients with primary node-negative breast cancer are cured by local therapy alone. Many patients receive overtreatment by adjuvant chemotherapy due to inadequate risk assessment. So far, few clinical trials have prospectively evaluated tumor biology based prognostic factors. Risk assessment by a biological algorithm including invasion factors urokinase-type plasminogen activator (uPA) and its inhibitor plasminogen activator inhibitor type 1 (PAI-1) will assess up to 35-55% of node-negative patients as low-risk and thus avoid chemotherapy. In contrast, a clinical-pathological algorithm will only classify 20-40% of patients as low-risk. High-risk node-negative patients should receive chemotherapy. Anthracycline-based regimens are accepted as a standard, the additional benefit of taxanes remains an open question. The international NNBC3 ('Node Negative Breast Cancer 3-Europe') trial compares biological risk assessment (UP) using invasion factors uPA/PAI-1 with a clinical-pathological algorithm (CP). In this trial, the type of risk assessment (CP or UP) was chosen upfront by each center for its patients. Fresh frozen tissue was obtained to determine uPA/PAI-1 using an enzyme-linked immunosorbent assay (ELISA). Patients assessed as high-risk were stratified by human epidermal growth factor receptor 2 (HER2) status and then randomised to receive anthracycline-containing chemotherapy 5-Fluorouracil (F)/Epirubicin (E)/Cyclophosphymide (C) or an anthracycline-taxane sequence (FE100C*6 versus FE100C*3 followed by Docetaxel100*3). In this trial, 4,149 node-negative patients with operable breast cancer from 153 centers in Germany and France were included since 2002. Measurement of uPA/PAI-1 by ELISA was performed with standardised central quality assurance for 2,497 patients (60%) from 56 'UP'-centers. The NNBC 3-Europe trial showed that inclusion of patients into a clinical phase III trial is feasible based on biological testing of

    Full Text Available Introduction. Predicting the aggressiveness of prostate cancer at biopsy is invaluable in making treatment decisions. In this paper we review the differential expression of genes and microRNAs identified through microarray analysis as potentially useful markers for prostate cancer prognosis and discuss some of the challenges associated with their development. Methods. A review of the literature was conducted through Medline. Articles were identified through searches of the following terms: “prostate cancer AND differential expression”, “prostate cancer prognosis”, and “prostate cancer AND microRNAs”. Results. Though numerous differentially expressed genes and microRNAs were identified as possible prognostic markers, the significance of several of these genes is either debated due to conflicting results or is not validated in other study populations. A few of the articles constructed predictive nomograms using a panel of biomarkers which require further validation. Challenges to the development of useful markers include different methodology, cancer heterogeneity, and sampling error. These can be overcome by categorizing prognostic factors into particular gene pathways or by supplementing biopsy information with blood or urine-based biomarkers. Conclusion. Though biomarkers based on differential expression offer the potential to improve decision making concerning prostate cancer, further validation of their utility and accuracy at the biopsy level is needed.

    Many elderly patients suffer from lung cancers, but it is not clear if their lung cancers differ from those of younger patients. In this study, we compared genetic and prognostic characteristics of lung cancers of patients aged ≥75 years with those of patients aged ≤ 64 years. In the genetic analysis, we explored 292 surgically treated non-squamous cell lung cancers with known mutational status of epidermal growth factor (EGFR) and anaplastic lymphoma kinase (ALK). In the prognostic analysis, we retrospectively analyzed 405 surgically treated non-small cell lung cancers (NSCLCs) before the era of routine clinical application of post-surgical adjuvant chemotherapy. Postsurgical recurrence-free survival (RFS) was compared between elderly patients and younger counterparts. The genetic analysis showed elderly non-squamous cell lung cancer patients to have higher prevalence of EGFR mutations (53.1 % vs 42.0%, P = 0.15) and lower prevalence of the ALK translocation (0 % vs 4.5%, P = 0.23) than their younger counterparts. The prognostic analysis showed postsurgical RFS was similar between the elderly NSCLC patients and the younger patients. However in multivariate analysis, adjusting for gender, smoking status, pathological stage, and histology, elderly patients had significantly worse prognoses (HR 1.57, 95% CI, 1.08-2.29; P = 0.02) compared with younger patients. These results suggest differences in genetic and prognostic aspects between elderly lung cancer patients and younger lung cancer patients. PMID:23251849

    A number of reports indicated that Aurora-A or Aurora-B overexpression represented a negative prognostic factor in several human malignancies. In thyroid cancer tissues a deregulated expression of Aurora kinases has been also demonstrated, butno information regarding its possible prognostic role in differentiated thyroid cancer is available. Here, weevaluated Aurora-A and Aurora-B mRNA expression and its prognostic relevance in a series of 87 papillary thyroid cancers (PTC), with a median follow-up of 63 months. The analysis of Aurora-A and Aurora-B mRNA levels in PTC tissues, compared to normal matched tissues, revealed that their expression was either up- or down-regulatedin the majority of cancer tissues. In particular, Aurora-A and Aurora-B mRNA levels were altered, respectively, in 55 (63.2%) and 79 (90.8%) out of the 87 PTC analyzed.A significant positive correlation between Aurora-A and Aurora-B mRNAswas observed (p=0.001). The expression of both Aurora genes was not affected by the BRAFV600E mutation. Univariate, multivariate and Kaplan-Mayer analyses documented the lack of association between Aurora-A or Aurora-B expression and clinicopathological parameterssuch as gender, age, tumor size, histology, TNM stage, lymph node metastasis and BRAF status as well asdisease recurrences or disease-free interval. Only Aurora-B mRNA was significantly higher in T(3-4) tissues, with respect to T(1-2) PTC tissues. The data reported here demonstrate that the expression of Aurora kinases is deregulated in the majority of PTC tissues, likely contributing to PTC progression. However, differently from other human solid cancers, detection of Aurora-A or Aurora-B mRNAs is not a prognostic biomarker inPTC patients. PMID:25807528

    International Nuclear Information System (INIS)

    Objective: To determine the frequency of human epidermal growth factor receptor 2 (HER-2/neu) positivity and to correlate its status in breast cancer patients with other prognostic markers. Methods: The comparative cross-sectional study was conducted at the Department of Histopathology, Liaquat National Hospital, Karachi, from January 1 to October 31, 2010. It included all specimens of mastectomy and lumpectomy with axillary tissue. Incisional, trucut and wedge biopsies as well as all non-epithelial tumours were excluded. All samples were processed as per standard guidelines and were evaluated by immunohistochemistry. SPSS 10 was used for statistical analysis. Results: The age of the 100 cases in the study ranged from 20 to 82 years with a mean of 51+-17.6 years. Two (2%) of the patients were males. HER-2/neu over-expression increased with increasing tumour size, grade, lymph node metastasis and with oestrogen receptor and progesterone receptor negativity. No significant correlation of HER-2/neu was seen with the age of patient and with the tumour type. Conclusions: The expression of HER-2/neu was associated with decrease in oestrogen receptor and progresterone receptor positivity, and increase in tumour size, high tumour grade and lymph node metastasis.

    We have investigated prognostic factors for survival in a series of 26 patients with chordoma treated in Lyon, France, between 1979 and 1993. In this series, the median progression-free (PFS) and overall survival (OS) was 10 and 90 months, respectively. In univariate analysis, PFS, but not OS, was found significantly longer in males as compared to females (median: 19 versus 7 months, P = 0.05); and patients under 60 years of age had a longer PFS (median: 18 versus 6 months; P = 0.06) and OS (median: 108 versus 47 +, P = 0.05) than older patients. A favourable prognostic subgroup including male patients under 60 years and a poor prognostic group including female patients and male over 60 years were thus defined (median PFS: 36 versus 6 months, P = 0.001; median OS: 108 versus 55+, P = 0.15). Primary treatment combining surgery and postoperative radiotherapy associated with a longer PFS than surgery only (median: 36 versus 7 months, P 0.002) in the whole series in both prognostic subgroups.

And the alternative splicing variant lacking exon Ⅷ was especially investigated.Methods:Total RNA was isolated using Trizol reagent from 63 epithelial ovarian cancer tissues and then reverse-transcripted into cDNA. ERCC1 mRNA expression level was evaluated by TaqMan real-time quantitative RT-PCR and the alternative splicing variant lacking exon Ⅷ was especially investigated. All patients were follow-up to determine the survival time after surgery. Results: ①Total and the full length ERCC1 mRNA expression level in chemotherapy sensitive group was lower than in resistant group and the difference had statistical significance( P = 0.013, P=0.009, respectively). The alternative splicing variant lacking exon Ⅷ expression level had no statistical significance between the two groups( P = 0.085);② Low expression group of total and full length ERCC1 mRNA had longer survival time than high expression group and the difference had statistical significance( P = 0.012, P = 0.008, respectively). The alternative splicing variant lacking exon Ⅷ had no statistical significance between the high and low groups (P=0.07) .Conclusions:ERCC1 mRNA expression level was a prognostic factor for epithelial ovarian cancer patients receiving platinum-based chemotherapy. The alternative splicing variant lacking exon Ⅷ could not predict chemotherapy response and survival time and was not a prognostic factor for epithelial ovarian cancer patients.%目的:研究切除修复交叉互补基因1(ERCC1)在卵巢上皮性癌组织中的mRNA表达水平与患者对铂类药物化疗反应及生存期的关系,并探讨ERCC1基因缺失第Ⅷ外显子变异剪接体的临床意义.方法:使用TRIZol试剂提取63例卵巢上皮性癌组织总RNA,逆转录为cDNA后,TaqMan实时荧

    Mycosis fungoides is the most prevalent form of primary cutaneous T-cell lymphoma. Patients frequently present with early-stage disease typically associated with a favourable prognosis and survival of 10-35 years, but over 25% may progress to advanced disease with a median survival mycosis fungoides may have a worse outcome than those with tumour-stage (IIB). The more recent staging system of the European Organisation for the Research and Treatment of Cancer/International Society for Cutaneous Lymphoma has been designed to reflect tumour burden at different sites. However, this staging system has not been validated prospectively for prognosis. Furthermore, this staging system does not include a detailed measurement of skin tumour burden, as indicated by the modified skin weighted severity assessment tool. This assessment measures body surface area of disease and is weighted to record patch, plaque and tumour to produce a numerical value from 0·5 to 400 and is an established endpoint for clinical studies. Nor does this staging include clinicopathological features associated with a poor prognosis such as folliculotropism. Here we review the clinical, haematological, pathological and genotypic parameters outside the staging system, which may affect survival in mycosis fungoides and Sézary syndrome. Most studies are retrospective and single centre. The identification of poor prognostic factors may be used to develop a prognostic index to use alongside staging, which may be of benefit in mycosis fungoides/Sézary syndrome to identify patients with a potentially poor prognosis.

    Objective To investigate the diagnostic and prognostic value of total and free prostate-specific antigen (PSA) in breast cancer women. Methods Using the microparticle enzyme immunoassay system, we measured the concentrations of these markers in the sera of 85 women with breast cancer and in 30 healthy women.Results Free PSA levels were significantly higher in women with breast cancer than healthy women (P <0. 05 ).The percentage of free PSA predominant subjects was 37. 6% in breast cancer patients and 3. 3% in healthy women.In women with breast cancer,total PSA positivity was 23.5% and free PSA positivity was 27. 1%. When compared to negatives,total PSA positive patients had a higher percentage of lymph node involvement tamours ( P >0. 05).However, patients with predominant free PSA had a higher percentage of early stage than patients with predominant PSA-ACT. Conclusion This study indicate clinical significance of preoperative measurement of serum total and free PSA in diagnosis and prognosis of women with breast cancer. The expression of KLKs is correlated with carcinogenesis of breast cancer.

    Pathologists' contribution in the determination of prognosis in invasive penile squamous cell carcinoma is crucial. The TNM staging system is based on the identification of pathological data. There are multiple pathologically based factors believed to be important in relation to the rates of regional inguinal lymph node and specific cancer death. Among them are tumor site, size, histological subtypes, thickness or anatomical level of invasion, tumor front, and vascular or perineural invasion. The identification of these factors determines the prognostic profile of patients with penile cancer. These factors are used for the construction of pathological risk groups, prognostic index, or nomograms and are helpful in the prediction of nodal metastasis or patients' outcome. This review will describe in detail the influential pathological prognostic factors present in each tumor category emphasizing the impact of especial histological subtypes in tumor spread and final outcome. There are few studies comprehensibly addressing the relation of tumor morphology and prognosis according to histological types. We are summarizing findings of prognostic factors in 3 different series for the most common types and individual series in more recently described tumor entities. We had found a broad correlation of special subtypes of penile squamous cell carcinomas that made regional nodal status and final outcome predictable according to histological features of the tumor. These findings permitted grouping special subtypes of squamous cell carcinomas into prognosis risk groups of low, intermediate, and high. In the first category of excellent prognoses are the usual grade I, verrucous, papillary NOS, pseudohyperplastic and cuniculatum carcinomas. In the second group, there are the grade II usual, mixed and warty carcinomas. The third category of tumors, with the worst prognosis is composed of high grade usual, basaloid, warty-basaloid, papillary basaloid, and sarcomatoid carcinomas. We

    Full Text Available OBJECTIVE: We have measured the concentration of immunoreactive neutrophil elastase (ir-NE in the tumor extracts of 313 primary human breast cancers. Sufficient time has elapsed, and we are now ready to analyze its prognostic value in human breast cancer. METHODS: ir-NE concentration in tumor extracts was determined with an enzyme-linked immunosorbent assay that enables a rapid measurement of both free-form ir-NE and the α1-protease inhibitor-complexed form of ir-NE. We analyzed the prognostic value of this enzyme in human breast cancer in univariate and multivariate analyses. RESULTS: Patients with breast cancer tissue containing a high concentration of ir-NE had poor survival compared to those with a low concentration of ir-NE at the cutoff point of 9.0 µg/100 mg protein (P = .0012, which had been previously determined in another group of 49 patients. Multivariate stepwise analysis selected lymph node status (P= .0004; relative risk = 1.46 and ir-NE concentration (P= .0013; relative risk = 1.43 as independent prognostic factors for recurrence. CONCLUSIONS: Tumor ir-NE concentration is an independent prognostic factor in patients with breast cancer who undergo curative surgery. This enzyme may play an active role in tumor progression that leads to metastasis in human breast cancer.

    The nodal stage of colorectal cancer is based on the number of positive nodes.It is inevitably affected by the number of removed lymph nodes,but lymph node ratio can be unaffected.We investigated the value of lymph node ratio in stage Ⅲ colorectal cancer in this study.The clinicopathologic factors and follow-up data of 145 cases of stage Ⅲ colorectal cancer between January 1998 and December 2008 were analyzed retrospectively.The Pearson and Spearman correlation analyses were used to determine the correlation coefficient,the Kaplan-Meier method was used to analyze survival,and the Cox proportional hazard regression model was used for multivariate analysis in forward stepwise regression.We found that lymph node ratio was not correlated with the number of removed lymph nodes (r =-0.154,P =0.065),but it was positively correlated with the number of positive lymph nodes (r =0.739,P <0.001) and N stage (r =0.695,P < 0.001),Kaplan-Meier survival analysis revealed that tumor configuration,intestinal obstruction,serum carcinoembryonic antigen (CEA) concentration,T stage,N stage,and lymph node ratio were associated with disease-free survival of patients with stage Ⅲ colorectal cancer (P < 0.05).Multivariate analysis showed that serum CEA concentration,T stage,and lymph node ratio were prognostic factors for disease-free survival (P < 0.05),whereas N stage failed to achieve significance (P =0.664).We confirmed that lymph node ratio was a prognostic factor in stage Ⅲ colorectal cancer and had a better prognostic value than did N stage.

    Accumulating evidence suggests that tumor-infiltrating lymphocytes (TILs)1, particularly CD8+T cells2 , are associated with improved disease-free and overall survival in triple-negative breast cancer (TNBC3). To evaluate the functions of TILs in breast cancer, we performed gene expression analysis...... of TILs isolated from frozen tumor sections of TNBC patients who experienced no recurrence or progression for at least 5 years (good prognosis) for comparison with those who had progression in the first 2 years post-surgery (bad prognosis). The results showed that 398 genes showed significantly altered...

    To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

    The incidence of male breast cancer (MBC) is rising. Current treatment regimens for MBC are extrapolated from female breast cancer (FBC), based on the assumption that FBC prognostic features and therapeutic targets can be extrapolated to MBC. However, there is yet little evidence that prognostic features that have been developed and established in FBC are applicable to MBC as well. In a recent study on FBC, a combination of mitotic index and Bcl2 expression proved to be of strong prognostic v...

    Full Text Available Background. In this study, we investigated the prognostic role of homotypic tumor cell cannibalism in different cancer types. Methods. The phenomenon of one cell being internalized into another, which we refer to as “cell-in-cell event,” was assessed in 416 cases from five head and neck cancer cohorts, as well as one anal and one rectal cancer cohort. The samples were processed into tissue microarrays and immunohistochemically stained for E-cadherin and cleaved caspase-3 to visualize cell membranes and apoptotic cell death. Results. Cell-in-cell events were found in all of the cohorts. The frequency ranged from 0.7 to 17.3 cell-in-cell events per mm2. Hardly any apoptotic cells were found within the cell-in-cell structures, although apoptotic cell rates were about 1.6 to two times as high as cell-in-cell rates of the same tissue sample. High numbers of cell-in-cell events showed adverse effects on patients’ survival in the head and neck and in the rectal cancer cohorts. In multivariate analysis, high frequency was an adverse prognostic factor for overall survival in patients with head and neck cancer (p=0.008. Conclusion. Cell-in-cell events were found to predict patient outcomes in various types of cancer better than apoptosis and proliferation and might therefore be used to guide treatment strategies.

    Background Previous studies showed that the prognostic factors for superficial transitional cell carcinoma of the bladder varied with the findings of different cohorts. Few multivariate analyses of prognostic factors for superficial bladder tumors have been reported in China and bladder preservation as a prognostic index of superficial bladder tumors is limited and scarce in Chinese patients. This study was conducted to analyze a group of risk factors for prognostic outcomes for patients with primary superficial transitional cell carcinoma of the bladder.Methods Between January 1980 to December 2000, 198 patients [172 men and 26 women; mean age (52.98±11.28) years] with primary superficial transitional cell carcinoma who were pathologically classified as Ta or T1 in Hunan Provincial Tumor Hospital (Changsha, China) were enrolled in this study. Surgical methods included local resection and electric coagulation of bladder tumors, transurethral resection of bladder tumors and partial cystectomy. After initial surgical treatment, patients were followed through a cystoscopy every three months during the first two years and every six months thereafter in the design of retrospective cohort. Survival analysis was performed to analyze risk factors of the prognostic outcomes for transitional cell carcinoma of the bladder.Canonical correlation analysis was conducted to present and interpret synthetically the multi-correlation between all kinds of prognostic outcomes and risk factor in multiply dimensions.Results The average follow-up period was (6.65±4.74) years. Assessments at three, five, and 10 years showed recurrence rates, respectively, of (28.32 ± 3.45)%, (35.31 ± 3.83)%, and (42.48 ± 4.40)%; progression rates of (8.89±2.14)%, (15.16±2.94)%, and (23.88±4.19)%; bladder-preservation rates of (94.68± 1.74)%, (93.87±1.91)%, and (91.51±2.49)%; metastasis rates of (8.25±2.05)%, (11.24±2.47)%, and (28.94±4.93)%; and cancer-related survival rates of (95.02 ±1

    PURPOSE: Several management options are available to patients with stage I seminoma, including adjuvant radiotherapy, surveillance, and adjuvant chemotherapy. We performed a pooled analysis of patients from the four largest surveillance studies to better delineate prognostic factors associated with...... disease progression. PATIENTS AND METHODS: Individual patient data were obtained from each center (Princess Margaret Hospital, Danish Testicular Cancer Study Group, Royal Marsden Hospital, and Royal London Hospital) for 638 patients. Tumor characteristics (size, histologic subtype, invasion of rete testis.......3 to 3.2) and invasion of the rete testis (hazard ratio 1.7; 95% CI, 1.1 to 2.6) remained as important predictors for relapse. CONCLUSION: We have identified size of primary tumor and rete testis invasion as important prognostic factors for relapse in patients with stage I seminoma managed with...

    Full Text Available Introduction: Radiomics extracts and mines large number of medical imaging features in a non-invasive and cost-effective way. The underlying assumption of radiomics is that these imaging features quantify phenotypic characteristics of entire tumor. In order to enhance applicability of radiomics in clinical oncology, highly accurate and reliable machine learning approaches are required. In this radiomic study, thirteen feature selection methods and eleven machine learning classification methods were evaluated in terms of their performance and stability for predicting overall survival in head and neck cancer patients. Methods: Two independent head and neck cancer cohorts were investigated. Training cohort HN1 consisted 101 HNSCC patients. Cohort HN2 (n=95 was used for validation. A total of 440 radiomic features were extracted from the segmented tumor regions in CT images. Feature selection and classification methods were compared using an unbiased evaluation framework. Results: We observed that the three feature selection methods MRMR (AUC = 0.69, Stability = 0.66, MIFS (AUC = 0.66, Stability = 0.69, and CIFE (AUC = 0.68, Stability = 0.7 had high prognostic performance and stability. The three classifiers BY (AUC = 0.67, RSD = 11.28, RF (AUC = 0.61, RSD = 7.36, and NN (AUC = 0.62, RSD = 10.52 also showed high prognostic performance and stability. Analysis investigating performance variability indicated that the choice of classification method is the major factor driving the performance variation (29.02% of total variance. Conclusions: Our study identified prognostic and reliable machine learning methods for the prediction of overall survival of head and neck cancer patients. Identification of optimal machine-learning methods for radiomics based prognostic analyses could broaden the scope of radiomics in precision oncology and cancer care.

    Full Text Available Asthma is a major health problem affecting millions of children worldwide. The prevalence of asthmain children tends to increase annually in the world. Therefore, identification of the prognostic factorsfor episodic asthma is important to perform early prevention of asthma attacks in children. Thestudy was performed to identify the prognostic factors for frequent episodic asthma in children. Thiswas a retrospective cohort study involving asthmatic children who attended the Emergency Unit orOutpatient Clinic of the Department of Pediatrics, Dr. Sardjito General Hospital, Yogyakarta. Theinclusion criteria were asthmatic children aged over 7 years, suffering from asthma over 2 years andgetting agreement from their parents as expressed by signed an informed consent. The exclusioncriteria were children with other chronic obtructive pulmonary diseases beside asthma and childrenwith cardiovascular diseases. Subjects were grouped into two groups i.e. Case Group and ControlGroup. The Case Group was children with frequent episodic asthma while the Control Group waschildren with infrequent episodic asthma. Prognostic factors for episodic asthma were then gatheredby giving a questionnaire to their parents. Regression analysis was used to evaluate the relationshipbetween prognostic factors and episodic asthma. A total of 94 subjects comprising 37 (36.4%subjects with frequent episodic asthma and 57 (63.6% subjects with infrequent episodic asthmawere involved in the study. Furthermore, response to initial theraphy was significantly associatedwith frequent episodic asthma (RR= 8.64; 95%CI= 0.47-2.50; p=0.001. Whereas, nutritionalstatus, patients age when asthma diagnosed, exclusive breastfeeding, maternal education, exposureof secondhand smoke and welfare were not (p>0.05. In conclusion, the initial therapy is prognosticfactors for frequent episodic asthma in children.

    Full Text Available Recent studies have shown that miR-155 play a positive role in the development of carcinoma. This meta-analysis aimed to identify the role of miR-155 in the survival of non-small cell lung cancer patients.Eligible studies were identified through database searches. Relevant data were extracted from each eligible study to assess the correlation between miR-155 expression and survival in lung carcinoma patients. The hazard ratios (HRs and 95% confidence intervals (CIs of the patients' outcomes in relation to miR-155 were calculated. A total of 6 studies were included for this meta-analysis. For overall survival (OS, recurrence-free survival (RFS, disease-free survival (DFS, and cancer-specific survival (CSS, the combined HRs and 95% CIs were not statistically significant. Additionally, in Asian and America subgroups, greater expression levels of miR-155 were related to poor prognoses for lung cancer (HR 1.71 95% CI: 1.22-2.40, P = 0.002, HR 2.35 95% CI: 1.42-3.89 P = 0.001, while no significant relationship was present in a Europe subgroup (HR 0.75 95%CI: 0.27-2.10, P = 0.587.These results suggest that miR-155 expression is not significantly related to non-small cell lung cancer patients except in patients from Asian and America.

    Junjie Peng

    Full Text Available To develop prognostic nomograms for predicting outcomes in patients with locally advanced rectal cancers who do not receive preoperative treatment.A total of 883 patients with stage II-III rectal cancers were retrospectively collected from a single institution. Survival analyses were performed to assess each variable for overall survival (OS, local recurrence (LR and distant metastases (DM. Cox models were performed to develop a predictive model for each endpoint. The performance of model prediction was validated by cross validation and on an independent group of patients.The 5-year LR, DM and OS rates were 22.3%, 32.7% and 63.8%, respectively. Two prognostic nomograms were successfully developed to predict 5-year OS and DM-free survival rates, with c-index of 0.70 (95% CI = [0.66, 0.73] and 0.68 (95% CI = [0.64, 0.72] on the original dataset, and 0.76 (95% CI = [0.67, 0.86] and 0.73 (95% CI = [0.63, 0.83] on the validation dataset, respectively. Factors in our models included age, gender, carcinoembryonic antigen value, tumor location, T stage, N stage, metastatic lymph nodes ratio, adjuvant chemotherapy and chemoradiotherapy. Predicted by our nomogram, substantial variability in terms of 5-year OS and DM-free survival was observed within each TNM stage category.The prognostic nomograms integrated demographic and clinicopathological factors to account for tumor and patient heterogeneity, and thereby provided a more individualized outcome prognostication. Our individualized prediction nomograms could help patients with preoperatively under-staged rectal cancer about their postoperative treatment strategies and follow-up protocols.

    Background and purpose: The aim of this study was to assess the potential prognostic factors in patients with primary invasive vaginal carcinoma (PIVC) treated with radical irradiation. Patients and methods: The analysis was performed on 77 patients with PIVC treated between 1985 and 2005 in the Maria Sklodowska-Curie Memorial Institute of Oncology, Cancer Center in Krakow. A total of 36 patients (46.8 %) survived 5 years with no evidence of disease (NED). The following groups of factors were assessed for potential prognostic value: population-based (age), clinical (Karnofsky Performance Score [KPS], hemoglobin level, primary location of the vaginal lesion, macroscopic type, length of the involved vaginal wall, FIGO stage), microscopic (microscopic type, grade, mitotic index, presence of atypical mitoses, lymphatic vessels invasion, lymphocytes/plasmocytes infiltration, focal necrosis, VAIN-3), immunohistochemical (protein p53 expression, MIB-1 index), cytofluorometric (ploidity, index DI, S-phase fraction, proliferation index SG2M) factors. Results: Significantly better 5-year NED was observed in patients: < 60 years, KPS {<=} 80, FIGO stage I and II, grade G1-2, MIB-1 index < 70, S-phase fraction < 10, and proliferation index < 25. Independent factors for better prognosis in the multivariate Cox analysis were age < 60 years, FIGO stage I or II, and MIB-1 index < 70. Conclusion: Independent prognostic factors in the radically irradiated PIVC patients were as follows: age, FIGO stage, MIB-1 index. (orig.)

    Xiaowen Liu

    Full Text Available BACKGROUND AND OBJECTIVE: The prognosis varied among the patients with the same stage, therefore there was a need for new prognostic and predictive factors. The aim of this study was to evaluate the relationship of apoptosis-related biological markers such as p53, bcl-2, bax, and c-myc, and clinicopathological features and their prognostic value. METHODS: From 1996 to 2007, 4426 patients had undergone curative D2 gastrectomy for gastric cancer at Fudan University Shanghai Cancer Center. Among 501 patients, the expression levels of p53, bcl-2, bax, and c-myc were examined by immunohistochemistry. The prognostic value of biological markers and the correlation between biological markers and other clinicopathological factors were investigated. RESULTS: There were 339 males and 162 females with a mean age of 57. The percentages of positive expression of p53, bcl-2, bax, and c-myc were 65%, 22%, 43%, and 58%, respectively. There was a strong correlation between p53, bax, and c-myc expression (P=0.00. There was significant association between bcl-2, and bax expression (P<0.05. p53 expression correlated with histological grade (P=0.01; bcl-2 expression with pathological stage (P=0.00; bax expression with male (P=0.02, histological grade (P=0.01, Borrmann type (P=0.01, tumor location (P=0.00, lymph node metastasis (P=0.03, and pathological stage (P=0.03; c-myc expression with Borrmann type (P=0.00. bcl-2 expression was related with good survival in univariate analysis (P=0.01. Multivariate analysis showed that bcl-2 expression and pathological stage were defined as independent prognostic factors. There were significant differences of overall 5-year survival rates according to bcl-2 expression or not in stage IIB (P=0.03. CONCLUSION: The expression of bcl-2 was an independent prognostic factor for patients with gastric cancer; it might be a candidate for the gastric cancer staging system.

  1. Prognostic indices in stereotactic radiotherapy of brain metastases of non-small cell lung cancer

    International Nuclear Information System (INIS)

    Our purpose was to analyze the long-term clinical outcome and to identify prognostic factors after Linac-based stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) on patients with brain metastases (BM) from non-small cell lung cancer (NSCLC). We performed a retrospective analysis of survival on 90 patients who underwent SRS or FSRT of intracranial NSCLC metastases between 04/2004 and 05/2014 that had not undergone prior surgery or whole brain radiotherapy (WBRT) for BM. Follow-up data was analyzed until May 2015. Potential prognostic factors were examined in univariable and multivariable analyses. The Golden Grading System (GGS), the disease-specific graded prognostic assessment (DS-GPA), the RADES II prognostic index as well as the NSCLC-specific index proposed by Rades et al. in 2013 (NSCLC-RADES) were calculated and their predictive values were tested in univariable analysis. The median follow-up time of the surviving patients was 14 months. The overall survival (OS) rate was 51 % after 6 months and 29.9 % after 12 months. Statistically significant factors of better OS after univariable analysis were lower International Union Against Cancer (UICC) stage at first diagnosis, histology of adenocarcinoma, prior surgery of the primary tumor and lower total BM volume. After multivariable analysis adenocarcinoma histology remained a significant factor; higher Karnofsky Performance Score (KPS) and the presence of extracranial metastases (ECM) were also significant. The RADES II and the NSCLC-RADES indices were significant predictors of OS. However, the NSCLC-RADES failed to differentiate between intermediate- and low-risk patients. The DS-GPA and GGS were not statistically significant predictors of survival in univariable analysis. The ideal prognostic index has not been defined yet. We believe that more specific indices will be developed in the future. Our results indicate that the histologic subtype of NSCLC could add to the prognostic

  2. Triple negative breast carcinoma is a prognostic factor in Taiwanese women

    International Nuclear Information System (INIS)

    Currently, there is a debate as to whether triple negative breast carcinoma (TNBC) has a worse prognosis than non-TNBC. Our aim was to determine whether TNBC is a prognostic factor for survival. We identified 1,048 Taiwanese breast carcinoma patients, of whom 167 (15.9%) had TNBC. Data used for analysis were derived from our cancer registry database for women with breast cancer who were diagnosed between 2002 January and 2006 December. In the Kaplan-Meier analysis, tumor subgroup (TNBC vs. non-TNBC) was a prognosis factor related to 5-year overall survival. In the univariate analysis, tumor subgroup (TNBC vs. non-TNBC) was a significant factor related to 5-year overall survival, in addition to age, tumor size, lymph node, metastasis, grade, stage, estrogen receptor status, progesterone receptor status, and HER2 overexpression status. In the multivariate analysis, tumor subgroup was not a significant factor related to 5-year disease-free survival (DFS). In node-positive patients, tumor subgroup was a significant factor related to 5-year overall survival, in addition to age, tumor size, metastasis, and grade. In node-negative patients, tumor subgroup was not a significant factor related to 5-year disease-free survival and 5-year overall survival. Our results indicated that TNBC patients in Taiwan have worse 5-year overall survival than non-TNBC patients. Notably, in node-positive patients, TNBC played a prognostic role in 5-year overall survival

    Full Text Available Whether lymphovascular invasion (LVI is an independent prognostic factor in prostate cancer is still controversial. We retrospectively investigated its predictive role in disease progression following radical prostatectomy. The histological sections of radical prostatectomies from 71 clinically localized, prostatic adenocarcinoma patients were reviewed for LVI. Pre- and postoperative follow-up data were collected. LVI was identified in 15.5% of cases. Univariate analysis showed a significant association between LVI and advanced pathological stage, higher Gleason score, positive surgical margins, extraprostatic extension, seminal vesicle invasion, and lymph node metastasis (each p < 0.05. Multivariate analyses pointed to vascular involvement as a strong and independent predictor for PSA failure (p = 0.023, and reduced biochemical progression-free survival (p = 0.019. LVI in radical prostatectomy is an adverse prognostic finding that must be recorded in the pathology report.

Recent reports have shown contradicting results on the role of PTP4A2 in breast cancer progression. Considering this, we aimed to investigate the prognostic value of PTP4A2 in five independent breast cancer data sets (minimum 198 patients per cohort, totaling 1,124 patients in the Gene Expression Omnibus Database. We found that high expression of PTP4A2 was a favorable prognostic marker in all five independent breast cancer data sets, as well as in the combined cohort, with a hazard ratio of 0.68 (95% confidence interval =0.56–0.83; P<0.001. Low PTP4A2 expression was associated with estrogen receptor-negative tumors and tumors with higher histological grading; furthermore, low expression was inversely correlated with the expression of genes involved in proliferation, including MKI67 and the MCM gene family encoding the minichromosome maintenance proteins. These findings suggest that PTP4A2 may play a role in breast cancer progression by dysregulating cell proliferation. PTP4A2 expression was

  9. Baseline Cardiopulmonary Function as an Independent Prognostic Factor for Survival of Inoperable Non-Small-Cell Lung Cancer After Concurrent Chemoradiotherapy: A Single-Center Analysis of 161 Cases

    International Nuclear Information System (INIS)

    Purpose: Little is known about the effects of cardiopulmonary function on the prognosis of concurrent chemoradiotherapy in patients with inoperable non-small-cell lung cancer (NSCLC). Methods and Materials: A retrospective analysis of the effects of tumor- and patient-related factors and parameters of cardiopulmonary function and heart morphology on the feasibility, toxicity, and prognosis was performed. Results: Cardiopulmonary function had no effect on the toxicity or feasibility of treatment; effects on survival were observed in the univariate analysis. Median survival varied as follows: cardiac function: 13.0 ± 1.6 months for left ventricular ejection fraction (LVEF) > 50% vs. 10.0 ± 1.9 months for LVEF ≤ 50% (p = 0.003); pulmonary function: 16.0 ± 0.6 months for no lung function deficits (vital capacity [VC] ≥ 60%, forced expiratory volume in 1 s ≥ 80%, and diffusing capacity of the lung for carbon monoxide (DLCO) ≥60%) vs. 14.0 ± 1.5 months for one or two function deficits vs. 8.0 ± 1.5 months for three lung function deficits (p = 0.001); T stage: 19.0 ± 3.1 months for rcT0/cT1/cT2 vs. 12.0 ± 0.8 months for cT3/cT4 (p = 0.039); and age: 11.0 ± 1.5 months for <60 years vs. 18.0 ± 2.5 months for 60-69 years vs. 12.0 ± 1.2 months for ≥70 years (p = 0.008). Prognostic factors identified in the multivariate analysis were LVEF ≤50% (p = 0.043; hazard ratio [HR], 1.74), reduced pulmonary function (p = 0.001; HR, 1.71 or 5.05) and T stage (p = 0.026; HR: 1.71). Conclusions: In addition to T-stage, cardiac and pulmonary function variables affected the survival of non-small-cell lung cancer patients after chemoradiotherapy.

  12. Prognostic Impact of the 6th and 7th American Joint Committee on Cancer TNM Staging Systems on Esophageal Cancer Patients Treated With Chemoradiotherapy

    International Nuclear Information System (INIS)

    Purpose: The new 7th edition of the American Joint Committee on Cancer TNM staging system is based on pathologic data from esophageal cancers treated by surgery alone. There is no information available on evaluation of the new staging system with regard to prognosis of patients treated with chemoradiotherapy (CRT). The objective of this study was to evaluate the prognostic impact of the new staging system on esophageal cancer patients treated with CRT. Methods and Materials: A retrospective review was performed on 301 consecutive esophageal squamous cell carcinoma patients treated with CRT. Comparisons were made of the prognostic impacts of the 6th and 7th staging systems and the prognostic impacts of stage and prognostic groups, which were newly defined in the 7th edition. Results: There were significant differences between Stages I and III (p < 0.01) according to both editions. However, the 7th edition poorly distinguishes the prognoses of Stages III and IV (p = 0.36 by multivariate analysis) in comparison to the 6th edition (p = 0.08 by multivariate analysis), although these differences were not significant. For all patients, T, M, and gender were independent prognostic factors by multivariate analysis (p < 0.05). For the Stage I and II prognostic groups, survival curves showed a stepwise decrease with increase in stage, except for Stage IIA. However, there were no significant differences seen between each prognostic stage. Conclusions: Our study indicates there are several problems with the 7th TNM staging system regarding prognostic factors in patients undergoing CRT.

    2011-01-01

    Full Text Available Abstract Background Inflammatory breast cancer (IBC is the most aggressive form of breast cancer. In non-IBC, the cysteine protease cathepsin B (CTSB is known to be involved in cancer progression and invasion; however, very little is known about its role in IBC. Methods In this study, we enrolled 23 IBC and 27 non-IBC patients. All patient tissues used for analysis were from untreated patients. Using immunohistochemistry and immunoblotting, we assessed the levels of expression of CTSB in IBC versus non-IBC patient tissues. Previously, we found that CTSB is localized to caveolar membrane microdomains in cancer cell lines including IBC, and therefore, we also examined the expression of caveolin-1 (cav-1, a structural protein of caveolae in IBC versus non-IBC tissues. In addition, we tested the correlation between the expression of CTSB and cav-1 and the number of positive metastatic lymph nodes in both patient groups. Results Our results revealed that CTSB and cav-1 were overexpressed in IBC as compared to non-IBC tissues. Moreover, there was a significant positive correlation between the expression of CTSB and the number of positive metastatic lymph nodes in IBC. Conclusions CTSB may initiate proteolytic pathways crucial for IBC invasion. Thus, our data demonstrate that CTSB may be a potential prognostic marker for lymph node metastasis in IBC.

    Purpose. To investigate the prognostic factors for visual outcome in traumatic cataract patients. Methods. The demographic features of traumatic cataract patients in Central China were studied. The factors that might influence the visual outcome were analyzed. The sensitivity and specificity of OTS (ocular trauma score) in predicting VA were calculated. Results. The study enrolled 480 cases. 65.5% of patients achieved VA at >20/60. The factors associated with the final VA were initial VA, injury type, wound location, the way of cataract removal, and IOL implantation. The sensitivities of OTS in predicting the VA at NLP (nonlight perception), LP/HM (light perception/hand motion), and ≥20/40 were 100%. The specificity of OTS to predict the final VA at 1/200-19/200 and 20/200-20/50 was 100%. Conclusion. The prognostic factors were initial VA, injury type, wound location, cataract removal procedure, and the way of IOL implantation. The OTS has good sensitivity and specificity in predicting visual outcome in traumatic cataract patients in long follow-up. PMID:27595014

    Background The latest version of the American Joint Committee on Cancer (AJCC) TNM staging system has not comprehensively evaluated the impact of tumour length on survival in patients with esophageal squamous cell carcinoma.Our study explored the relationship between tumour length and clinicopathological characteristics as well as long-term survival.Methods All 202 cases of esophageal resections done from January 1,2004 to December 31,2008 in Huashan Hospital,Fudan University were reviewed and followed up.Results Patients with tumour length >3 cm were related to more advanced tumour stage (X2=55.9,P <0.001),more metastatic lymph nodes (X2=14.6,P <0.001),increased metastatic lymph node ratio (x2=16.1,P <0.001) and worse overall TNM stage (X2=48.1,P <0.001).Univariate and multivariate analyses indicated that tumour length was a significant prognostic risk factor (95% CI 0.235-0.947,P=0.035).Subgroup analyses disclosed that tumour length was a valuable prognostic predictor in patients with lower T stage,absence of metastatic lymph nodes and lower TNM stage.Conclusions Esophageal tumour length is a predictive factor for long-term survival especially for lower tumour stage,absence of metastatic lymph nodes and lower TNM stage patients.Tumour length should be incorporated in the staging system as an important grouping factor for better prognostic evaluation.

    For palliative care of spinal bone metastases, stability assessment is of crucial importance. Pathological fractures, instability-related patient immobility and the extent of bone metastasis have been reported to affect patient outcome and these parameters have therefore been used for treatment stratification. We report on stability-dependent fracture and survival rates in over 300 non-small cell lung cancer (NSCLC) patients. Data from 303 patients with 868 osteolytic metastases treated with radiotherapy (RT) between 2000 and 2012 were evaluated retrospectively. In NSCLC patients with bone metastases only, the retrospective 6- and 12-month overall survival (OS) rates were 76.7 and 47.2%, respectively. In patients with additional non-bone distant metastases, these values were 60.0 and 34.0%, respectively. Survival rates were significantly lower in patients with multiple bone metastases and in those suffering pathological fractures (p=0.017). No significant impact of histological type, location of spinal lesions or treatment regime was detected. Furthermore, stability assessment revealed no influence of vertebral column stability on patient outcome (p=0.739). Our analysis demonstrated a correlation between the pathological fractures of bone lesions, the number of bone metastases, additional distant metastases and survival. The results offer a rationale for future prospective investigations. (orig.)

    Gastric cancer is an important cause for mortality and morbidity worldwide; it lies in the fourt rank as a cause of cancer-related death in males and in the fifth rank of cancer-related death in women. The prognosis of advanced/metastatic gastric cancer cases looks poor with the majority of available therapeutics. Thus, novel therapeutic strategies in this setting have been considered a priority for leading cooperative oncology groups. Hedgehog(Hh) pathway aberrations have sparked particular interest as prognostic markers with data from multiple studies showing consistent evidence of a poor prognostic value of Gli over expression in gastric cancer while on the other hand the prognostic significance of Hh protein over expression (particularly SHH) was not consistent among different studies. This review article revises the prognostic and potential therapeutic opportunities in the targeting of hedgehog pathway in gastric cancer. PMID:25680409

    Cancer immunosurveillance relies on effector/memory tumor-infiltrating CD8(+) T cells with a T-helper cell 1 (TH1) profile. Evidence for a natural killer (NK) cell-based control of human malignancies is still largely missing. The KIT tyrosine kinase inhibitor imatinib mesylate markedly prolongs the survival of patients with gastrointestinal stromal tumors (GIST) by direct effects on tumor cells as well as by indirect immunostimulatory effects on T and NK cells. Here, we investigated the prognostic value of tumor-infiltrating lymphocytes (TIL) expressing CD3, Foxp3, or NKp46 (NCR1) in a cohort of patients with localized GIST. We found that CD3(+) TIL were highly activated in GIST and were especially enriched in areas of the tumor that conserve class I MHC expression despite imatinib mesylate treatment. High densities of CD3(+) TIL predicted progression-free survival (PFS) in multivariate analyses. Moreover, GIST were infiltrated by a homogeneous subset of cytokine-secreting CD56(bright) (NCAM1) NK cells that accumulated in tumor foci after imatinib mesylate treatment. The density of the NK infiltrate independently predicted PFS and added prognostic information to the Miettinen score, as well as to the KIT mutational status. NK and T lymphocytes preferentially distributed to distinct areas of tumor sections and probably contributed independently to GIST immunosurveillance. These findings encourage the prospective validation of immune biomarkers for optimal risk stratification of patients with GIST. PMID:23592754

    Background MicroRNA (miR)-126, acting as a tumor suppressor, has been reported to inhibit the invasion of gastric cancer cells in part by targeting v-crk sarcoma virus CT10 oncogene homologue (CRK). The aim of this study was to investigate the clinical significance of miR-126/CRK axis in gastric cancer. Methods miR-126 and CRK mRNA expression levels were detected by real-time quantitative reverse transcription polymerase chain reaction in 220 self-pairs of gastric cancer and adjacent noncancerous tissues. Results Expression levels of miR-126 and CRK mRNA in gastric cancer tissues were, respectively, lower and higher than those in adjacent noncancerous tissues (both P<0.001). Low miR-126 expression and high CRK expression, alone or in combination, were all significantly associated with positive lymph node and distant metastases and advanced TNM stage of human gastric cancer (all P<0.05). We also found that the overall survival rates of the patients with low miR-126 expression and high CRK expression were, respectively, shorter than those with high miR-126 expression and low CRK expression. Interestingly, miR-126-low/CRK-high expression was associated with a significantly worse overall survival of all miR-126/CRK groups (P<0.001). Moreover, multivariate analysis identified miR-126 and/or CRK expression as independent prognostic factors for patients with gastric cancer. Notably, the prognostic relevance of miR-126 and/or CRK expression was more obvious in the subgroup of patients with TNM stage IV. Conclusion Dysregulation of miR-126/CRK axis may promote the malignant progression of human gastric cancer. miR-126 and CRK combined expression may serve as an independent predictor of overall survival in patients with advanced gastric cancer.

    Full Text Available BACKGROUND: Cancer stem cells (CSCs are a subset of tumor cells with capacity to self-renew and generate the diverse cells that make up the tumor. The aim of this study is to evaluate the prognostic value of CSCs in a highly homogeneous population of stage II colon cancer. METHODS: One hundred stage II colon cancer patients treated by the same surgical team between 1977 and 2005 were retrospectively analyzed. None of the patients received adjuvant chemotherapy. Inmunohistochemistry expression of CD133, NANOG and CK20 was scored, using four levels: 50% positivity. Kaplan-Meier analysis and log rank test were used to compare survival. RESULTS: The average patient age was 68 years (patients were between 45-92 years of age and median follow up was 5.8 years. There was recurrent disease in 17 (17%; CD133 expression (defined by >10% positivity was shown in 60% of the tumors, in 95% for NANOG and 78% for CK20. No correlation was found among expression levels of CD133, NANOG or CK20 and relapse-free survival (RFS or overall survival (OS. However, a statistical significant correlation was found between established pathological prognostic factors and RFS and OS. CONCLUSIONS: Stem Cell quantification defined by CD133 and NANOG expression has no correlation with RFS or OS in this cohort of Stage II colon cancer.

    Background This study evaluated the prognostic impact of D2 lymphadenectomy combined with splenectomy in patients with advanced proximal gastric cancer and lymph node metastasis at the splenic hilum (No. 10 lymph nodes).Methods The clinical records of 216 patients with advanced proximal gastric cancer and No.10 lymph node metastasis who underwent D2 curative resection were retrospectively analyzed. Seventy-three patients underwent simultaneous splenectomy (splenectomy group), while 143 patients did not (spleen-preserving group). Five-year survival rates, mean numbers of dissected No.10 lymph nodes and metastatic No.10 lymph nodes, and operative morbidity and mortality were calculated and compared between the two groups. Potential prognostic factors were evaluated by univariate and multivariate analysis.Results The 5-year survival rate was 30.0% for the splenectomy group and 19.7% for the spleen-preserving group (X~2=14.73, P 0.05).Conclusions Splenectomy is beneficial for No.10 lymph node dissection in patients with advanced proximal gastric cancer. To improve patient prognosis, total gastrectomy with splenectomy is recommended for patients with T3 proximal gastric cancer who have No. 10 lymph node metastasis.

    Full Text Available Apoptosis may occur via a death receptor-dependent or independent (mitochondrial pathway. The mitochondrial pathway is regulated by small molecules, such as smac/Diablo, which activates caspase cascades. This study examined smac/DIABLO expression in 76 patients with endometrioid endometrial cancers. Presence of smac/DIABLO was quantified by Western blot analysis using nonfixed fresh frozen tissues. Its appearance was found in 55 (72% of examined tumors. Smac/DIABLO expression significantly correlated with tumor grade (p<0.001. Patients with positive smac/DIABLO tumors had a longer disease-specific survival when compared with those with negative tumors in the 10-year follow-up (p=0.043. The study demonstrated that negative smac/DIABLO expression was a poor prognostic sign.

    infection, but most cases develop in women aged over 50 years through poorly understood genetic mechanisms. Rho-associated coiled-coil-containing protein kinase 1 (ROCK1) has been implicated in many cellular processes, but its function in vulvar cancer has never been examined. In this study, we aimed...... to determine the prognostic value of ROCK1 gene and protein analysis in vulvar squamous cell carcinoma (VSCC). METHODS: ROCK1 expression levels were measured in 16 vulvar tumour samples and adjacent normal tissue by qRT-PCR. Further, 96 VSCC samples were examined by immunohistochemistry (IHC) to confirm...... tissue compared with the tumour samples (p = 0.016). By IHC, 100% of invasive front areas of the tumour and 95.8% of central tumour areas were positive for ROCK1. Greater expression of ROCK1 was associated with the absence of lymph node metastasis (p = 0.022) and a lower depth of invasion (p = 0...

  8. Carcinoma of the Thyroid. Preoperative diagnostic and prognostic factors

    International Nuclear Information System (INIS)

    By improving preoperative diagnosis and identification of important prognostic factors of thyroid carcinoma (TC) it might be possible to decrease the number of diagnostic surgical intervantions and to give patients with a confirmed TC a more adequate treatment. Preoperative diagnosis: consecutive series of 83 patients with scintigrams and of 203 patients with fine-needle aspiration (AC) with subsequently histologically confirmed TC were evaluated as well as 217 patients with confirmed benign thyroid disorders. The most common scintigraphic appearance was a solitary reduced uptake (70%). The sensitivity of AC for medullary and undifferentiated TC was 0.82-0.84, but it was for papillary (occult TC excluded) 0.58 and for follicular TC 0.42. A 'cold' nodule with also a decreased thallium-uptake is mostly a benign disorder, but with an increased uptake it might be a well-differentiated TC or a follicular adenoma. These could, however, be significantly separated by the thallium-elimination rate (p=0.0001). Prognostic factors: During 1955-1972, 262 patients with histologically verified TC were referred to the Department and 226 of these (86%) with a median follow-up of 11 years form the basis for prognostic multivariate analyses. According to these analyses, and when deaths in intercurrent disease were estimated, neither age at diagnosis nor sex were found to be important predictors of survival of TC. The following predictors were identified: for papillary TC: tumour extension beyond the thyroid capsule and marked cellular atypia; for follicular TC: tumour extension beyond the thyroid capsule, marked cellular atypia and distant metastases; for medullary TC: tumour extension beyond the thyroid capsule.

    Several prognostic factors in oncology have been established over the years, such as performance status, tumor size, and disease stage. The identification of prognostic and predictive factors is becoming increasingly important in medical research, particularly as scientific discoveries have led to better understanding of diseases and genetics, resulting in tailored therapy. Advances in drug discovery and better understanding of the mechanism of action, may also identify factors that may be prognostic and/or predictive. Prognostic or predictive factors may include patient characteristics such as age, ethnicity, sex, or smoking status, disease characteristics such as disease stage or nodal status, and molecular markers such as HER2 amplification and K ras mutation.It can be challenging to distinguish whether a factor is prognostic or predictive, based on what is reported in the literature. This article is intended to help the reader assess whether a factor is prognostic and/or predictive.

  10. Spinal bone metastases in gynecologic malignancies: a retrospective analysis of stability, prognostic factors and survival

    International Nuclear Information System (INIS)

    The aim of this retrospective study was to evaluate the stability of spinal metastases in gynecologic cancer patients (pts) on the basis of a validated scoring system after radiotherapy (RT), to define prognostic factors for stability and to calculate survival. Fourty-four women with gynecologic malignancies and spinal bone metastases were treated at our department between January 2000 and January 2012. Out of those 34 were assessed regarding stability using the Taneichi score before, 3 and 6 months after RT. Additionally prognostic factors for stability, overall survival, and bone survival (time between first day of RT of bone metastases and death from any cause) were calculated. Before RT 47% of pts were unstable and 6 months after RT 85% of pts were stable. Karnofsky performance status (KPS) >70% (p = 0.037) and no chemotherapy (ChT) (p = 0.046) prior to RT were significantly predictive for response. 5-year overall survival was 69% and 1-year bone survival was 73%. RT is capable of improving stability of osteolytic spinal metastases from gynecologic cancer by facilitating re-ossification in survivors. KPS may be a predictor for response. Pts who received ChT prior to RT may require additional bone supportive treatment to overcome bone remodeling imbalance. Survival in women with bone metastases from gynecologic cancer remains poor

    Full Text Available Abstract Background Our aim was to detect lymphatic endothelial marker podoplanin, lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1 and vascular endothelial growth factor receptor-3 (VEGFR-3 and study the prognostic relevance of lymphangiogenesis in non-small cell lung cancer (NSCLC. Materials 82 paraffin-embedded tissues and 40 fresh frozen tissues from patients with NSCLC were studied. Tumor samples were immunostained for the lymphatic endothelial markers. Lymphangiogenesis was assessed by immunohistochemical double stains for Podoplanin and Ki-67. The prognostic relevance of lymphangiogenesis-related clinicopathological parameters in NSCLC was evaluated. Results We found that the number of podoplanin positive vessels was correlated positively with the number of LYVE-1 positive vessels. Most of VEGFR-3 positive, few of LYVE-1 positive and none of podoplanin positive vessels were blood vessels. Peritumoral lymphatic vessel density (ptLVD, pathologic stage, lymph node status, lymphatic vessel invasion (LVI, vascular endothelial growth factor-C (VEGF-C expression and Ki-67 index of the endothelium cells of the micro lymphatic vessels (Ki67% were associated significantly with a higher risk of tumor progress. ptLVD, pathologic stage, lymph-node metastasis and Ki67% were independent prognostic parameters for overall survival. Conclusion Podoplanin positive ptLVD might play important roles in the lymphangiogenesis and progression of NSCLC. Patients with high podoplanin+ ptLVD have a poor prognosis.

    To evaluate whether serum Cathepsin S (Cat S) could serve as a biomarker for the diagnosis and prognosis of gastric cancer (GC), Enzyme-linked immuno sorbent assay (ELISA) was used to detect serum Cat S in 496 participants including healthy controls and patients with benign gastric diseases, gastric cancer, esophageal cancer, liver cancer, colorectal cancer, nasopharyngeal cancer and lung cancer. The levels of serum Cat S were significantly increased in cancer patients, especially in GC patients. The qRT-PCR, Western blotting, and immunohistochemical staining revealed the overexpression of Cat S in GC cell lines and tissues. The diagnostic value of serum Cat S for GC patients from controls resulted in an AUC of 0.803 with a sensitivity of 60.7% and a specificity of 90.0%. Moreover, the levels of serum Cat S were associated with GC tumor volume, lymphoid nodal status, metastasis status, and stages. Moreover, the patients with high levels of serum Cat S had a poorer overall survival. Univariate analysis revealed Cat S expression was a prognostic factor. The knockdown of Cat S significantly suppressed the migration and invasion of GC cells. This study suggested serum Cat S may be a potential biomarker for the diagnosis and prognosis of GC.

    Full Text Available The aim of the present study was to examine the factors of prognosis in patients with malignant pleural mesothelioma (MPM after combined and multimodality treatment, including the prognostic significance of preoperative intrapleural perfusion hyperthermo-chemotherapy (IPHC. Material and Methods: The study included 20 patients (11 men and 9 women aged from 30 to 70 years (mean age 51.9±8.5 years who underwent surgical treatment for MPM. The diagnosis of MPM was verified by immunohistochemical data. The patients were divided into two groups. Group 1 included 9 patients who underwent combined treatment that included the extrapleural pneumonectomy (EPP and 4 courses of adjuvant chemotherapy. Group 2 included 11 patients who received multimodality treatment (IPHC, EPP, and 4 courses of adjuvant chemotherapy. All patients were followed prospectively at three-monthly intervals for the first year and six-monthly thereafter until the last time of contact or death. Statistical analysis was performed by using Kaplan-Meier method and the log-rank test. Cox-regression model was used for multivariate analysis. Results: Patient’s age over 60 years and the sarcomatoid type of the tumor can be regarded as prognostic factors for poor survival in patients with MPM who underwent EPP. Application of IPHC as a part of a multimodality treatment enhances the survivability of MPM patients.

    Hospital records of 201 consecutive and histologically diagnosed non-Hodgkin's lymphoma patients were retrospectively analysed in an effort to determine the clinical prognostic factors affecting survival. The uncorrected five-year survival was 45%, and when corrected for other causes of death than lymphoma 48%. Response to the primary treatment, stage of the disease at diagnosis, occurrence of B-symptoms and age were strongly correlated to the final outcome. B-symptoms had negative effect on survival during the first year after the diagnosis, but not afterwards. Survival decreased with advancing age except in children, who had as poor survival as patients over 60 years of age. The primary site, sex or occurrence of extranodal lymphoma (43%) did not have influence on survival. Patients with a positive bone marrow aspiration biopsy did not have less favourable survival than other patients with stage IV lymphoma. Patients with a positive bipedal lymphangiogram had similar prognosis as those with a negative one. It is concluded that the most important prognostic factors other than histology in non-Hodgkin's lymphomas are response to the primary treatment, stage, age and occurrence of B-symptoms.

    Cartilage tympanoplasty is an established procedure for tympanic membrane and attic reconstruction. Cartilage has been used as an ossiculoplasty material for many years. The aim of this study was to evaluate hearing results of costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for middle ear cholesteatoma and to determine the presence of prognostic factors. Candidates for this study were patients affected by middle ear cholesteatoma whose ossicular chain was reconstructed with a chondroprosthesis. 67 cases of ossiculoplasty with total (TORP) or partial (PORP) chondroprosthesis were performed between January 2011 and December 2013. Follow-up examination included micro-otoscopy and pure tone audiometry. The guidelines of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology Head and Neck Surgery were followed and pure-tone average (PTA) was calculated as the mean of 0.5, 1, 2 and 4 kHz thresholds. Statistical analysis was performed with ANOVA tests and regression models. Average air-bone gap (ABG) significantly improved from 39.2 dB HL (SD 9.1 dB HL) to 25.4 dB HL (SD 11 dB HL) (p costal cartilage as material of choice when autologous ossicles are not available. The maintenance of the posterior canal wall was the only prognostic factor identified. PMID:26824916

    Six hundred and nine cases of invasive squamous cell carcinoma of the cervix uteri in a retrospective analysis (1953-1982) at the A.C. Camargo Hospital, Antonio Prudente Foundation, Sao Paulo, Brazil. The patients were submitted to radical surgery and radiation therapy, individually or in combination. A multivariate analysis of the different variables were performed according to the Cox`s regression method. The variables of prognosis value, in decreasing order of importance, were: the decade of patient`s admission, the modality of therapy employed, the presence of residual tumor in the surgical specimens and the clinical stage of the disease. Other variables like ethnic group, age of first menstrual flux, menopause, number of pregnancy, kind of delivery, number and kind of abortion, were found to be of no prognostic importance. The decade of admission was of independent prognostic significance. The presence of residual tumor in the surgical specimens was more important than lymph nodes spreading, but the overall survival was affected by the increase in the number of positive lymph nodes. Patient`s age was a weak prognostic factor accounting for a reduction in the survival time among cases with age upper to 45 years old. Radiation therapy sterilizes a considerable number of lymph nodes but not all of them in every patient. There are a specific group of patients where the radical surgery is necessary in order to carry a complete debulking of the disease. (author) 82 refs., 10 figs.

    Full Text Available To analyze the clinical features and prognostic factors associated with the survival of patients with a very rare occurrence of brain metastasis (BM from differentiated thyroid cancer (DTC.A total of 37 patients with DTC who were diagnosed with BM between 1995 and 2014 were included. We reviewed the clinical characteristics, treatment modalities, and image findings of BM. Factors associated with survival were evaluated, and the patients were divided into three prognostic groups (Groups A, B, and C for comparative analysis.The median age at BM was 63 years, and the median time from initial thyroid cancer diagnosis to BM was 3.8 years. The median survival and the 1-year actuarial survival rate after BM were 8.8 months and 47%, respectively. According to univariate and multivariate analyses, four good prognostic factors (GPFs were identified including age ≤ 60 years, PS ≤ ECOG 2, ≤ 3 BM sites, and without extracranial metastasis prior to BM. Three prognostic groups were designed based on age and number of remaining GPFs: patients ≤ 60 years of age with at least 2 GPFs (Group A had the most favorable prognosis with a median survival of 32.8 months; patients ≤ 60 years of age with fewer than 2 GPFs and those > 60 years of age with at least 2 GPFs (Group B had an intermediate prognosis with a median survival of 9.4 months; and patients > 60 years of age with fewer than 2 GPFs (Group C had the least favorable prognosis with a median survival of 1.5 months.The survival of patients with BM form DTC differed among the prognostic groups based on the total number of good prognostic factors.

  3. An 8-gene qRT-PCR-based gene expression score that has prognostic value in early breast cancer

    International Nuclear Information System (INIS)

    Gene expression profiling may improve prognostic accuracy in patients with early breast cancer. Our objective was to demonstrate that it is possible to develop a simple molecular signature to predict distant relapse. We included 153 patients with stage I-II hormonal receptor-positive breast cancer. RNA was isolated from formalin-fixed paraffin-embedded samples and qRT-PCR amplification of 83 genes was performed with gene expression assays. The genes we analyzed were those included in the 70-Gene Signature, the Recurrence Score and the Two-Gene Index. The association among gene expression, clinical variables and distant metastasis-free survival was analyzed using Cox regression models. An 8-gene prognostic score was defined. Distant metastasis-free survival at 5 years was 97% for patients defined as low-risk by the prognostic score versus 60% for patients defined as high-risk. The 8-gene score remained a significant factor in multivariate analysis and its performance was similar to that of two validated gene profiles: the 70-Gene Signature and the Recurrence Score. The validity of the signature was verified in independent cohorts obtained from the GEO database. This study identifies a simple gene expression score that complements histopathological prognostic factors in breast cancer, and can be determined in paraffin-embedded samples

    International Nuclear Information System (INIS)

    The aim of this retrospective study is to assess the necessity of staging laparotomy in the management of supradiaphragmatic CS I-II Hodgkin's disease. Prognostic factors and the usefulness of prognostic factor groups were also analyzed. From 1985 to 1995, fifty one patients who were diagnosed as supradiaphragmatic CS I-II Hodgkin's disease at Yonsei Cancer Center in Seoul, Korea were enrolled in this study. Age range was 4 to 67 with median age of 30. The number of patients with each CS I A, II A, and II B were 16, 25, and 10, respectively. Radiotherapy(RT) was delivered using 4 or 6 MV photon beam to a total dose of 19.5 to 55.6Gy (median dose : 45Gy) with a 1.5 to 1.8Gy per fraction. Chemotherapy(CT) was given in 2-12 cycles(median : 6 cycles). Thirty one patients were treated with RT alone, 4 patients with CT alone and 16 patients with combined chemoradiotherapy. RT volumes varied from involved fields(3), subtotal nodal fields(18) or mantle fields(26). Five-year disease-free survival rate(DFS) was 78.0% and overall survival rate(OS) was 87.6%. Fifty patients achieved a complete remission after initial treatment and 8 patients were relapsed. Salvage therapy was given to 7 patients, 1 with RT alone, 4 with CT alone, 2 with RT+CT. Only two patients were successfully salvaged. Feminine gender and large mediastinal adenopathy were significant adverse prognostic factors in the univariate analysis for DFS. The significant adverse prognostic factors of OS were B symptom and clinical stage. When patients were analyzed according to European Organization for Research and Treatment of Cancer(EORTC) prognostic factor groups, the DFS in patients with very favorable, favorable and unfavorable group was 100, 100 and 55.8%(p<0.05), and the OS in each patients' group was 100, 100 and 75.1%(p<0.05), respectively. In very favorable and favorable groups, the DFS and OS were all 100% by RT alone, but in unfavorable group, RT with CT had a lesser relapse rate than RT alone. The

    The serum tumor markers CYFRA 21-1, carcinoembryonic antigen (CEA), and squamous cell carcinoma antigen (SCCA) are useful in diagnosis and prognosis of non-small cell lung cancer (NSCLC). Cytologic tumor markers obtained during needle aspiration biopsies (NAB) of lung lesions are useful for NSCLC diagnosis. This study investigated the incremental prognostic value of cytologic tumor markers compared to serum tumor markers. This prospective study included 253 patients diagnosed with NSCLC by NAB with cytologic tumor marker analysis. Levels of cytologic CYFRA 21-1, CEA, SCCA, and their serum counterparts were followed up for survival analysis. Optimal cutoff values for each tumor marker were obtained for overall survival (OS) and progression-free survival (PFS) analyses. All patients were followed up for a median of 22.8 months. Using cutoff values of 0.44 ng/ml for C-SCCA, 2.0 ng/ml for S-SCCA, and 3.3 ng/ml for S-CYFRA, a multivariate analysis revealed that high S-SCCA (hazard ratio, HR, 1.84) and high C-SCCA (HR, 1.63) were independent predictive factors of OS. The 3-year overall survival rate was 55 vs. 80 % for high and low C-SCCA, respectively. Cytologic tumor marker level detection is easily obtainable and provides prognostic information for NSCLC. Cytologic tumor markers provide comparable prognostic information relative to serum tumor markers, with C-SCCA acting as a strong prognostic factor of overall survival and PFS. PMID:26432331

  7. Meta-analysis confirms BCL2 is an independent prognostic marker in breast cancer

    International Nuclear Information System (INIS)

    A number of protein markers have been investigated as prognostic adjuncts in breast cancer but their translation into clinical practice has been impeded by a lack of appropriate validation. Recently, we showed that BCL2 protein expression had prognostic power independent of current used standards. Here, we present the results of a meta-analysis of the association between BCL2 expression and both disease free survival (DFS) and overall survival (OS) in female breast cancer. Reports published in 1994–2006 were selected for the meta-analysis using a search of PubMed. Studies that investigated the role of BCL2 expression by immunohistochemistry with a sample size greater than 100 were included. Seventeen papers reported the results of 18 different series including 5,892 cases with an average median follow-up of 92.1 months. Eight studies investigated DFS unadjusted for other variables in 2,285 cases. The relative hazard estimates ranged from 0.85 – 3.03 with a combined random effects estimate of 1.66 (95%CI 1.25 – 2.22). The effect of BCL2 on DFS adjusted for other prognostic factors was reported in 11 studies and the pooled random effects hazard ratio estimate was 1.58 (95%CI 1.29–1.94). OS was investigated unadjusted for other variables in eight studies incorporating 3,910 cases. The hazard estimates ranged from 0.99–4.31 with a pooled estimate of risk of 1.64 (95%CI 1.36–2.0). OS adjusted for other parameters was evaluated in nine series comprising 3,624 cases and the estimates for these studies ranged from 1.10 to 2.49 with a pooled estimate of 1.37 (95%CI 1.19–1.58). The meta-analysis strongly supports the prognostic role of BCL2 as assessed by immunohistochemistry in breast cancer and shows that this effect is independent of lymph node status, tumour size and tumour grade as well as a range of other biological variables on multi-variate analysis.

    PTPRH is a receptor-type protein tyrosine phosphatase thought to be a potential regulator of tumorigenesis. The aim of the present study was to clarify the significance of PTPRH expression and its regulation by DNA methylation in non-small cell lung cancer (NSCLC), especially in lung adenocarcinoma (LADC). PTPRH mRNA expression was examined in 89 NSCLC and corresponding non-cancerous tissues. The correlation between DNA methylation and PTPRH gene expression was investigated in another cohort that consisted of 145 patients with LADC, a major NSCLC subtype. Gene regulation by DNA methylation was assessed using a DNA methylation inhibitor. PTPRH mRNA expression was significantly upregulated in NSCLC. PTPRH DNA methylation was reduced in LADC samples and inversely correlated with mRNA expression. 5-Aza-2'-deoxycytidine treatment of lung cancer cell lines with low PTPRH expression, restored mRNA PTPRH expression levels. Furthermore, low PTPRH methylation was associated with shorter recurrence-free survival (P=1.64x10(-4)) and overall survival (P=5.54x10(-5)). Multivariate analysis revealed that PTPRH DNA methylation was an independent prognostic factor (P=6.88x10(-3)). It was confirmed that PTPRH is overexpressed in NSCLC. Furthermore, we determined that PTPRH is epigenetically regulated by DNA hypomethylation, with prognostic implications for LADC. PMID:26134684

  10. Improved prognostic classification of breast cancer defined by antagonistic activation patterns of immune response pathway modules

    International Nuclear Information System (INIS)

    Elucidating the activation pattern of molecular pathways across a given tumour type is a key challenge necessary for understanding the heterogeneity in clinical response and for developing novel more effective therapies. Gene expression signatures of molecular pathway activation derived from perturbation experiments in model systems as well as structural models of molecular interactions ('model signatures') constitute an important resource for estimating corresponding activation levels in tumours. However, relatively few strategies for estimating pathway activity from such model signatures exist and only few studies have used activation patterns of pathways to refine molecular classifications of cancer. Here we propose a novel network-based method for estimating pathway activation in tumours from model signatures. We find that although the pathway networks inferred from cancer expression data are highly consistent with the prior information contained in the model signatures, that they also exhibit a highly modular structure and that estimation of pathway activity is dependent on this modular structure. We apply our methodology to a panel of 438 estrogen receptor negative (ER-) and 785 estrogen receptor positive (ER+) breast cancers to infer activation patterns of important cancer related molecular pathways. We show that in ER negative basal and HER2+ breast cancer, gene expression modules reflecting T-cell helper-1 (Th1) and T-cell helper-2 (Th2) mediated immune responses play antagonistic roles as major risk factors for distant metastasis. Using Boolean interaction Cox-regression models to identify non-linear pathway combinations associated with clinical outcome, we show that simultaneous high activation of Th1 and low activation of a TGF-beta pathway module defines a subtype of particularly good prognosis and that this classification provides a better prognostic model than those based on the individual pathways. In ER+ breast cancer, we find that

  17. Prognostic and Predictive Biomarkers in Colorectal Cancer. From the Preclinical Setting to Clinical Practice.

    Maurel, Joan; Postigo, Antonio

    2015-01-01

    Colorectal cancer (CRC) is the second largest cause of cancer mortality in Western countries, mostly due to metastasis. Understanding the natural history and prognostic factors in patients with metastatic CRC (mCRC) is essential for the optimal design of clinical trials. The main prognostic factors currently used in clinical practice are related to tumor behavior (e.g., white blood counts, levels of lactate dehydrogenase, levels of alkaline phosphatase) disease extension (e.g., presence of extrahepatic spread, number of organs affected) and general functional status (e.g., performance status as defined by the Eastern Cooperative Oncology Group). However, these parameters are not always sufficient to establish appropriate therapeutic strategies. First-line therapy in mCRC combines conventional chemotherapy (CHT) (e.g., FOLFOX, FOLFIRI, CAPOX) with a number of agents targeted to specific signaling pathways (TA) (e.g., panitumumab and cetuximab for cases KRAS/NRAS WT, and bevacizumab). Although the response rate to this combination regime exceeds 50%, progression of the disease is almost universal and only less than 10% of patients are free of disease at 2 years. Current clinical trials with second and third line therapy include new TA, such as tyrosin-kinase receptors inhibitors (MET, HER2, IGF-1R), inhibitors of BRAF, MEK, PI3K, AKT, mTORC, NOTCH and JAK1/JAK2, immunotherapy modulators and check point inhibitors (anti-PD-L1 and anti- PD1). Despite the identification of multiple prognostic and predictive biomarkers and signatures, it is still unclear how expression of many of these biomarkers is modulated by CHT and/or TA, thus potentially affecting response to treatment. In this review we analyzed how certain biomarkers in tumor cells and microenvironment influence the response to new TA and immune-therapies strategies in mCRC pre-treated patients. PMID:26452385

    AIM: To investigate the clinical characteristics and prognostic factors of a consecutive series of patients with severe acute pancreatitis (SAP).METHODS: Clinical data of SAP patients admitted to our hospital from January 2003 to January 2004 were retrospectively reviewed. Collected data included the age, gender, etiology,length of hospitalization, APACHE Ⅱ score at admission,local and organ/systemic complications of the patients.RESULTS: Of the 268 acute pancreatitis patients, 94 developed SAP. The mean age of SAP patients was 52 years, the commonest etiology was cholelithiasis (45.7%), the mean length of hospitalization was 70 d, the mean score of APACHE Ⅱ was 7.7. Fifty-four percent of the patients developed necrosis, 25% abscess, 58% organ/systemic failure. A total of 23.4% (22/94) of the SAP patients died. Respiratory failure was the most common organ clysfunction (90.9%) in deceased SAP patients, followed by cardiovascular failure (86.4%),renal failure (50.0%). In the SAP patients, 90.9% (20/22)developed multiple organ/systemic failures. There were significant differences in age, length of hospitalization,APACHE Ⅱ score and incidences of respiratory failure, renal failure, cardiovascular failure and hematological failure between deceased SAP patients and survived SAP patients.By multivariate logistic regression analysis, independent prognostic factors for mortality were respiratory failure,cardiovascular failure and renal failure.CONCLUSION: SAP patients are characterized by advanced age, high APACHE Ⅱ score, organ failure and their death is mainly due to multiple organ/systemic failures. In patients with SAP, respiratory, cardiovascular and renal failures can predict the fatal outcome and more attention should be paid to their clinical evaluation.

  3. Diagnostic accuracy and prognostic impact of restaging by magnetic resonance imaging after preoperative chemoradiotherapy in patients with rectal cancer

    International Nuclear Information System (INIS)

    Background: The prognostic role of restaging rectal magnetic resonance imaging (MRI) in patients with preoperative CRT has not been established. The goal of this study was to evaluate the diagnostic accuracy and prognostic role of radiological staging by rectal MRI after preoperative chemoradiation (CRT) in patients with rectal cancer. Methods: A total of 231 consecutive patients with rectal cancer who underwent preoperative CRT and radical resection from January 2008 to December 2009 were prospectively enrolled. The diagnostic accuracy and prognostic significance of post-CRT radiological staging by MRI was evaluated. Results: The sensitivity, specificity, positive predictive value, and negative predictive value of radiological diagnosis of good responders (ypTNM stage 0–I) were 32%, 90%, 65%, and 69%, respectively. The overall accuracy of MRI restating for good responders was 68%. The 5-year disease-free survival rates of patients with radiological and pathological TNM stage 0, stage I, and stage II–III were 100%, 94%, and 76%, respectively (P = 0.037), and 97%, 87%, and 73%, respectively (P = 0.007). On multivariate analysis, post-CRT radiological staging by MRI was an independent prognostic factor for disease-free survival. Conclusion: Radiological staging by MRI after preoperative CRT may be an independent predictor of survival in patients with rectal cancer

    Full Text Available Using pharmacological unmasking microarray, we identified promoter DNA methylation of cysteine dioxygenase 1 (CDO1 gene in human cancer. In this study, we assessed the clinicopathological significance of CDO1 methylation in primary breast cancer (BC with no prior chemotherapy. The CDO1 DNA methylation was quantified by TaqMan methylation specific PCR (Q-MSP in 7 BC cell lines and 172 primary BC patients with no prior chemotherapy. Promoter DNA of the CDO1 gene was hypermethylated in 6 BC cell lines except SK-BR3, and CDO1 gene expression was all silenced at mRNA level in the 7 BC cell lines. Quantification of CDO1 methylation was developed using Q-MSP, and assessed in primary BC. Among the clinicopathologic factors, CDO1 methylation level was not statistically significantly associated with any prognostic factors. The log-rank plot analysis elucidated that the higher methylation the tumors harbored, the poorer prognosis the patients exhibited. Using the median value of 58.0 as a cut-off one, disease specific survival in BC patients with CDO1 hypermethylation showed significantly poorer prognosis than those with hypomethylation (p = 0.004. Multivariate Cox proportional hazards model identified that CDO1 hypermethylation was prognostic factor as well as Ki-67 and hormone receptor status. The most intriguingly, CDO1 hypermethylation was of robust prognostic relevance in triple negative BC (p = 0.007. Promoter DNA methylation of CDO1 gene was robust prognostic indicator in primary BC patients with no prior chemotherapy. Prognostic relevance of the CDO1 promoter DNA methylation is worthy of being paid attention in triple negative BC cancer.

    Background: The proportion of node-negative breast cancer patients has been increasing with improvement of diagnostic modalities and early detection. However, there is a 20–30% recurrence in node-negative breast cancers. Determining who should receive adjuvant therapy is challenging, as the majority are cured by surgery alone. Hence, it requires further stratification using additional prognostic and predictive factors. Subjects and Methods: Ours is a single institution retrospective study, on 300 node-negative breast cancer cases, who underwent primary surgery over a period of 7 years (2005–2011). We excluded all cases who took NACT. Prognostic factors of age, size, lymphovascular emboli, estrogen receptor (ER), progesterone receptor (PR), HER2neu Ki-67, grade and molecular classification were analyzed with respect to those with and without early events (recurrence, metastases or second malignancy, death) using-Pearson Chi-square method and logistic regression method for statistical analysis. Results: Majority belonged to the age group of 50–70 years. On univariate analysis, size >5 cm (P = 0.03) and ER negativity had significant association (P = 0.05) for early failures; PR negativity and lymphovascular emboli (LVE) had borderline significance (P = 0.07). Multivariate analysis showed size >5 cm to be significant (P = 0.04) and LVE positivity showed borderline significant association (P = 0.07) with early failures. About 62% belonged to luminal category followed by basal-like (25%) in molecular classification. Conclusions: ER negativity, PR negativity, LVE/lymphovascular invasion positivity and size >5 cm (T3 and T4) are associated with poor prognosis in node-negative breast cancers. PMID:26981506

    Clinical and quality of life (QL) variables from an EORTC clinical trial of first line chemotherapy in advanced breast cancer were used in a prognostic factor analysis of survival and response to chemotherapy. For response, different final multivariate models were obtained from forward and backward selection methods, suggesting a disconcerting instability. Quality of life was measured using the EORTC QLQ-C30 questionnaire completed by patients. Subscales on the questionnaire are known to be highly correlated, and therefore it was hypothesized that multicollinearity contributed to model instability. A correlation matrix indicated that global QL was highly correlated with 7 out of 11 variables. In a first attempt to explore multicollinearity, we used global QL as dependent variable in a regression model with other QL subscales as predictors. Afterwards, standard diagnostic tests for multicollinearity were performed. An exploratory principal components analysis and factor analysis of the QL subscales identified at most three important components and indicated that inclusion of global QL made minimal difference to the loadings on each component, suggesting that it is redundant in the model. In a second approach, we advocate a bootstrap technique to assess the stability of the models. Based on these analyses and since global QL exacerbates problems of multicollinearity, we therefore recommend that global QL be excluded from prognostic factor analyses using the QLQ-C30. The prognostic factor analysis was rerun without global QL in the model, and selected the same significant prognostic factors as before.

    Full Text Available Background. There is a considerable dissimilarity in the survival duration of the patients with gastric cancer. We aimed to assess the systemic inflammatory response (SIR and nutritional status of these patients before the commencement of chemotherapy to find the appropriate prognostic factors and define a new score for predicting metastasis. Methods. SIR was assessed using Glasgow Prognostic Score (GPS. Then a score was defined as prealbumin/CRP based prognostic score (PCPS to be compared with GPS for predicting metastasis and nutritional status. Results. 71 patients with gastric cancer were recruited in the study. 87% of patients had malnutrition. There was a statistical difference between those with metastatic (n=43 and those with nonmetastatic (n=28 gastric cancer according to levels of prealbumin and CRP; however they were not different regarding patient generated subjective global assessment (PG-SGA and GPS. The best cut-off value for prealbumin was determined at 0.20 mg/dL and PCPS could predict metastasis with 76.5% sensitivity, 63.6% specificity, and 71.4% accuracy. Metastatic and nonmetastatic gastric cancer patients were different in terms of PCPS (P=0.005. Conclusion. PCPS has been suggested for predicting metastasis in patients with gastric cancer. Future studies with larger sample size have been warranted.

  12. Pleural Mesothelioma: Diagnostic Problems and Evaluation of Prognostic Factors

    International Nuclear Information System (INIS)

    Background: Malignant pleural mesothelioma (MPM) in Egypt is mainly attributed to an environmental origin i.e exposure to asbestos, with a high incidence in women and young adults. Immunohistochemistry and ultrastructural features aid in the diagnosis. The p27Kip 1 is a kinase inhibitor protein acting as a cell cycle regulator and a putative tumor suppressor gene playing a critical role i.n the pathogenesis of several human neoplasms. Aim: A clinico pathologic, immunohistochemical and ultrastructural study of mesothelioma in Egyptian patients, with identification of different prognostic factors. Material and Methods: Sixty-one cases of MPM were collected from the department of pathology at the NCI, Cairo. Cases were stained by monoclonal antibodies against CK5/6, calretinin, vimentin, CD15, CEA and p27. Results: More than half (57.4%) of the patients were residents in endemic areas; 50.8% were of epithelioid type. CK5/6 was positive in 45 (73.8%) cases, 39 (63.9%) cases were positive for vimentin, 49 (80.3%) cases were positive for calretinin. One case showed a focal weak positive reaction to CD 15. None of the cases stained for CEA. There was a statistically significant relation between p27 expression and the histopathologic type (p=0.02) between overall survival and age (p=0.01) histopathologic type (p=0.02) and stage (p=0.006). Conclusion: MPM is an increasing disaster in Egypt which is underestimated and neglected. A panel of immunohistochemical markers should be used for proper evaluation. p27 has proven to be a potential biologic prognostic marker for mesothelioma and more studies as regard its significance are recommended on a larger number

  13. Correlation of primary tumor FDG uptake with clinicopathologic prognostic factors in invasive ductal carcinoma of the breast

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the correlation of primary tumor FDG uptake to clinicopathological prognostic factors in invasive ductal carcinoma of the breast. We retrospectively reviewed 136 of 215 female patients with pathologically proven invasive ductal breast cancer from January 2008 to December 2011 who underwent F-18 FDG PET/CT for initial staging and follow-up after curative treatment with analysis of estrogen receptor (ER), progesterone receptor (PR) and human epithelial growth factor receptor 2 (HER2). The maximum standardized uptake value (SUVmax) of the primary breast tumor was measured and compared with hormonal receptor and HER2 overexpression status. The high SUVmax of primary breast tumors is significantly correlated with the clinicopathological factors: tumor size, histologic grade, TNM stage, negativity of ER, negativity of PR, HER2 overexpression and triple negativity. The recurrent group with non-triple negative cancer had a higher SUVmax compared with the non-recurrent group, though no significant difference in FDG uptake was noted between the recurrence and non-recurrent groups in subjects with triple-negative cancer. Lymph node involvement was the independent risk factor for cancer recurrence in the multivariate analysis. In conclusion, high FDG uptake in primary breast tumors is significantly correlated with clinicopathological factors, such as tumor size, histologic grade, TNM stage, negativity of the hormonal receptor, HER2 overexpression and triple negativity. Therefore, FDG PET/CT is a helpful prognostic tool to direct the further management of patients with breast cancer

    Full Text Available Abstract Background Currently, the TNM classification of malignant tumours based on clinicopathological staging remains the standard for colorectal cancer (CRC prognostication. Recently, we identified the mitochondrial oxidative phosphorylation chain as a consistently overrepresented category in the published gene expression profiling (GEP studies on CRC prognosis. Methods We evaluated associations of putative regulatory single nucleotide polymorphisms (SNPs in genes from the oxidative phosphorylation chain with survival and disease prognosis in 613 CRC patients from Northern Germany (PopGen cohort. Results Two SNPs in the 3′ untranslated region of UQCRB (complex III, rs7836698 and rs10504961, were associated with overall survival (HR = 0.52, 95% CI 0.32–0.85 and HR = 0.64, 95% CI 0.42–0.99, for TT carriers. These associations were restricted to the group of patients with cancer located in the colon (HR = 0.42, 95% CI 0.22–0.82 and HR = 0.46, 95% CI 0.25–0.83. Multivariate analysis indicated that both markers might act as independent prognostic markers. Additionally, the TT carriers were ~2 times more likely to develop tumours in the colon than in the rectum. Two SNPs in COX6B1 (complex IV were associated with lymph node metastasis in a dominant model (rs6510502, OR = 1.75, 95% CI 1.20–2.57; rs10420252, OR = 1.68, 95% CI 1.11–2.53; rs6510502 was associated also with distant metastasis (OR = 1.67, 95% CI 1.09–2.56 in a dominant model. Conclusions This is the first report suggesting that markers in genes from the mitochondrial oxidative chain might be prognostic factors for CRC. Additional studies replicating the presented findings are needed.

    Patrick N Harter

    Full Text Available The multifunctional molecule netrin-1 is upregulated in various malignancies and has recently been presented as a major general player in tumorigenesis leading to tumor progression and maintenance in various animal models. However, there is still a lack of clinico-epidemiological data related to netrin-1 expression. Therefore, the aim of our study was to elucidate the association of netrin-1 expression and patient survival in brain metastases since those constitute one of the most limiting factors for patient prognosis. We investigated 104 brain metastases cases for netrin-1 expression using in-situ hybridization and immunohistochemistry with regard to clinical parameters such as patient survival and MRI data. Our data show that netrin-1 is strongly upregulated in most cancer subtypes. Univariate analyses revealed netrin-1 expression as a significant factor associated with poor patient survival in the total cohort of brain metastasis patients and in sub-entities such as non-small cell lung carcinomas. Interestingly, many cancer samples showed a strong nuclear netrin-1 signal which was recently linked to a truncated netrin-1 variant that enhances tumor growth. Nuclear netrin-1 expression was associated with poor patient survival in univariate as well as in multivariate analyses. Our data indicate both total and nuclear netrin-1 expression as prognostic factors in brain metastases patients in contrast to other prognostic markers in oncology such as patient age, number of brain metastases or Ki67 proliferation index. Therefore, nuclear netrin-1 expression constitutes one of the first reported molecular biomarkers for patient survival in brain metastases. Furthermore, netrin-1 may constitute a promising target for future anti-cancer treatment approaches in brain metastases.

  17. Serum albumin is an important prognostic factor for carotid blowout syndrome

    International Nuclear Information System (INIS)

    Carotid blowout syndrome is a severe complication of head and neck cancer. High mortality and major neurologic morbidity are associated with carotid blowout syndrome with massive bleeding. Prediction of outcomes for carotid blowout syndrome patients is important for clinicians, especially for patients with the risk of massive bleeding. Between 1 January 2001 and 31 December 2011, 103 patients with carotid blowout syndrome were enrolled in this study. The patients were divided into groups with and without massive bleeding. Prognostic factors were analysed with proportional hazard (Cox) regressions for carotid blowout syndrome-related prognoses. Survival analyses were based on the time from diagnosis of carotid blowout syndrome to massive bleeding and death. Patients with massive bleeding were more likely to have hypoalbuminemia (albumin1000 cells/μl, P=0.041) and hypoalbuminemia (P=0.010) were important to prognosis. Concurrent chemoradiotherapy (P=0.007), elevated lactate dehydrogenase (>250 U/l; P=0.050), local recurrence (P=0.022) and hypoalbuminemia (P=0.038) were related to poor prognosis in carotid blowout syndrome-related death. In multivariate analysis, best supportive care and hypoalbuminemia were independent factors for both carotid blowout syndrome-related massive bleeding (P=0.000) and carotid blowout syndrome-related death (P=0.013), respectively. Best supportive care and serum albumin are important prognostic factors in carotid blowout syndrome. It helps clinicians to evaluate and provide better supportive care for these patients. (author)

    2015-01-01

    Full Text Available Although complete debulking surgery for epithelial ovarian cancer (EOC is more often achieved with interval debulking surgery (IDS following neoadjuvant chemotherapy (NACT, randomized evidence shows no long-term survival benefit compared to complete primary debulking surgery (PDS. We performed an observational cohort study of patients treated with debulking surgery for advanced EOC to evaluate the prognostic value of residual disease after debulking surgery. All patients treated between 1998 and 2010 in three Dutch referral gynaecological oncology centres were included. The prognostic value of residual disease after surgery for disease specific survival was assessed using Cox-regression analyses. In total, 462 patients underwent NACT-IDS and 227 PDS. Macroscopic residual disease after debulking surgery was an independent prognostic factor for survival in both treatment modalities. Yet, residual tumour less than one centimetre at IDS was associated with a survival benefit of five months compared to leaving residual tumour more than one centimetre, whereas this benefit was not seen after PDS. Leaving residual tumour at IDS is a poor prognostic sign as it is after PDS. The specific prognostic value of residual tumour seems to depend on the clinical setting, as minimal instead of gross residual tumour is associated with improved survival after IDS, but not after PDS.

    Transfer RNAs (tRNAs, key molecules in protein synthesis) have not been investigated as potential prognostic markers in breast cancer (BC), despite early findings of their dysregulation and diagnostic potential. We aim to comprehensively profile tRNAs from breast tissues and to evaluate their role as prognostic markers (Overall Survival, OS and Recurrence Free Survival, RFS). tRNAs were profiled from 11 normal breast and 104 breast tumor tissues using next generation sequencing. We adopted a Case-control (CC) and Case-Only (CO) association study designs. Risk scores constructed from tRNAs were subjected to univariate and multivariate Cox-proportional hazards regression to investigate their prognostic value. Of the 571 tRNAs profiled, 76 were differentially expressed (DE) and three were significant for OS in the CC approach. We identified an additional 11 tRNAs associated with OS and 14 tRNAs as significant for RFS in the CO approach, indicating that CC alone may not capture all discriminatory tRNAs in prognoses. In both the approaches, the risk scores were significant in the multivariate analysis as independent prognostic factors, and patients belonging to high-risk group were associated with poor prognosis. Our results confirmed global up-regulation of tRNAs in BC and identified tRNAs as potential novel prognostic markers for BC. PMID:27604545

    Full Text Available Epithelial ovarian cancer is the most lethal gynecological malignancy. Due to its lack of symptoms, this disease is diagnosed at an advanced stage when the cancer has already spread to secondary sites. While initial rates of response to first treatment is >80%, the overall survival rate of patients is extremely low, mainly due to development of drug resistance. To date, there are no reliable clinical factors that can properly stratify patients for suitable chemotherapy strategies. Clinical parameters such as disease stage, tumor grade and residual disease, although helpful in the management of patients after their initial surgery to establish the first line of treatment, are not efficient enough. Accordingly, reliable markers that are independent and complementary to clinical parameters are needed for a better management of these patients. For several years, efforts to identify prognostic factors have focused on molecular markers, with a large number having been investigated. This review aims to present a summary of the recent advances in the identification of molecular biomarkers in ovarian cancer patient tissues, as well as an overview of the need and importance of molecular markers for personalized medicine in ovarian cancer.

    Full Text Available OBJECTIVE: The prevalence of breast cancer varies among countries and regions. This retrospective study investigated the prognostic value of the lymph node ratio (LNR compared with the number of positive lymph nodes (pN in Chinese breast cancer patients. METHODS: The medical records of female breast cancer patients (N = 2591 were retrospectively evaluated. The association of LNR and TMN staging system were compared with respect to overall, disease-free, and distant metastasis-free survival. RESULTS: Out of 2591 patients, 2495 underwent modified radical surgery and 96 received breast conserving surgery. All patients had adjuvant chemotherapy following surgery. The median follow up period 66.9 months (range 5-168 months. The 5-year and 10-year overall survival rates were 89.3% and 78.8%, respectively, and 5-year disease-free survival and distant metastasis-free survival rates were 81.6% and 83.5%, respectively. Univariate analysis indicated that in general T, pN, LNR, as well as tumor expression of the estrogen receptor, progesterone receptor, and HER2 were associated with overall, disease-free, and distant metastasis-free survival (all P-values <0.05. Mutlivariate analysis found pN stage and LNR were independent predictors of overall, disease-free, and distant metastasis-free survival (all P-values <0.001. If pN stage and LNR were both included in a multivariate analysis, LNR was still an independent prognostic factor for overall, disease-free, and distant metastasis-free survival (all P-values <0.001. CONCLUSION: Our findings support the use of LNR as a predictor of survival in Chinese patients with breast cancer, and that LNR is superior to pN stage in determining disease prognosis.

    Full Text Available Abstract Objective The aim of this study was to assess the prognostic and predictive values of circulating tumor cell (CTC analysis in colorectal cancer patients. Patients and methods Presence of CTCs was evaluated in 60 colorectal cancer patients before systemic therapy - from which 33 patients were also evaluable for CTC analysis during the first 3 months of treatment - through immunomagnetic enrichment, using the antibodies BM7 and VU1D9 (targeting mucin 1 and EpCAM, respectively, followed by real-time RT-PCR analysis of the tumor-associated genes KRT19, MUC1, EPCAM, CEACAM5 and BIRC5. Results Patients were stratified into groups according to CTC detection (CTC negative, when all marker genes were negative; and CTC positive when at least one of the marker genes was positive. Patients with CTC positivity at baseline had a significant shorter median progression-free survival (median PFS 181.0 days; 95% CI 146.9-215.1 compared with patients with no CTCs (median PFS 329.0 days; 95% CI 299.6-358.4; Log-rank P Conclusion The present study provides evidence of a strong correlation between CTC detection and radiographic disease progression in patients receiving chemotherapy for colorectal cancer. Our results suggest that in addition to the current prognostic factors, CTC analysis represent a potential complementary tool for prediction of colorectal cancer patients’ outcome. Moreover, the present test allows for molecular characterization of CTCs, which may be of relevance to the creation of personalized therapies.

    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.

    Full Text Available Introduction. The small renal masses (SRMs have increased over the past two decades due to more liberal use of imaging techniques. SRMs have allowed discussions regarding their prognostic, diagnosis, and therapeutic approach. Materials and methods. Clinical presentation, incidental diagnosis, and prognosis factors of SRMs are discussed in this review. Results. SRMs are defined as lesions less than 4 cm in diameter. SRM could be benign, and most malignant SMRs are low stage and low grade. Clinical symptoms like hematuria are very rare, being diagnosed by chance (incidental in most cases. Size, stage, and grade are still the most consistent prognosis factors in (RCC. An enhanced contrast SRM that grows during active surveillance is clearly malignant, and its aggressive potential increases in those greater than 3 cm. Clear cell carcinoma is the most frequent cellular type of malign SRM. Conclusions. Only some SRMs are benign. The great majority of malign SRMs have good prognosis (low stage and grade, no metastasis with open or laparoscopic surgical treatment (nephron sparing techniques. Active surveillance is an accepted attitude in selected cases.

    AIM: To study the significance of scoring systems assessing severity and prognostic factors in patients with colonic perforation.METHODS: A total of 26 patients (9 men, 17 women;mean age 72.7±11.6 years) underwent emergency operation for colorectal perforation in our institution between 1993 and 2005. Several clinical factors were measured preoperatively and 24 h postoperatively. Acute physiology and chronic health evaluationⅡ (APACHE Ⅱ),Mannheim peritonitis index (MPI) and peritonitis index of Altona (PIA Ⅱ) scores were calculated preoperatively.RESULTS: Overall postoperative mortality rate was 23.1% (6 patients). Compared with survivors, nonsurvivors displayed low blood pressure, low serum protein and high serum creatinine preoperatively, and low blood pressure, low white blood cell count, low pH,low PaO2/FiO2, and high serum creatinine postoperatively.APACHE Ⅱ score was significantly lower in survivors than in non-survivors (10.4±3.84 vs19.3±2.87, P= 0.00003). Non-survivors tended to display high MPI score and low PIA Ⅱ score, but no significant difference was identified.CONCLUSION: Pre- and postoperative blood pressure and serum creatinine level appear related to prognosis of colonic perforation. APACHE Ⅱ score is most associated with prognosis and scores ≥ 20 are associated with significantly increased mortality rate.

    Objective The increasing incidence of thyroid nodules demands identification of risk factors for malignant disease. Several studies suggested the association of higher TSH levels with cancer, but influence of 25-hydroxyvitamin D (25OHD) is controversial. This study aimed to identify the relationship of thyroid cancer with higher TSH levels and hypovitaminosis D and to evaluate their influence on prognostic characteristics of papillary thyroid carcinomas (PTC). Methods We retrospectively evaluated 433 patients submitted to thyroidectomy for thyroid nodules. Patients were categorized according to quartiles of TSH and 25OHD levels. Clinicopathological features were analyzed. Results Subjects with thyroid carcinomas were more frequently male and younger compared to those with benign disease. Their median TSH levels were higher and adjusted odds-ratio (OR) for cancer in the highest-quartile of TSH (> 2.4 mUI/mL) was 2.36 (1.36–4.09). Although vitamin D deficiency/insufficiency was prevalent in our cohort (84%), no significant differences in 25OHD levels or quartile distribution were observed between benign and malignant cases. Among 187 patients with PTC, analyses of prognostic features revealed increased risk of lymph nodes metastases for subjects with highest-quartile TSH levels (OR = 3.7, p = 0.029). Decreased 25OHD levels were not overtly associated with poor prognosis in PTC. Conclusions In this cross-sectional cohort, higher TSH levels increased the risk of cancer in thyroid nodules and influenced its prognosis, particularly favoring lymph nodes metastases. On the other hand, no association was found between 25OHD levels and thyroid carcinoma risk or prognosis, suggesting that serum 25OHD determination may not contribute to risk assessment workup of thyroid nodules.

    Mitochondrial serine hydroxylmethyltransferase 2 (SHMT2) is a key enzyme in the serine/glycine synthesis pathway. SHMT2 has been implicated as a critical component for tumor cell survival. The aim of the present study was to evaluate the prognostic value and efficiency of SHMT2 as a biomarker in patients with breast cancer. Individual and pooled survival analyses were performed on five independent breast cancer microarray datasets. Gene signatures enriched by SHMT2 were also analyzed in these datasets. SHMT2 protein expression was detected using immunohistochemistry (IHC) assay in 128 breast cancer cases. Gene set enrichment analysis revealed that SHMT2 was significantly associated with gene signatures of mitochondrial module, cancer invasion, metastasis and poor survival among breast cancer patients (paggressiveness (TNM staging and Elson grade) in a dose-dependent manner (p<0.05). The prognostic performance of SHMT2 mRNA was comparable to other gene signatures and proved superior to TNM staging. Further analysis results indicated that SHMT2 had better prognostic value for estrogen receptor (ER)-negative breast cancer patients, compared to ER-positive patients. In cases involving stage IIb breast cancer, chemotherapy significantly extended survival time among patients with high SHMT2 expression. These results indicate that SHMT2 may be a valuable prognostic biomarker in ER-negative breast cancer cases. Furthermore, SHMT2 may be a potential target for breast cancer treatment and drug discovery. PMID:27666119

    The incomplete clinical efficacy of anti-tumor immunotherapy can depend on the presence of an immunosuppressive environment in the host that supports tumor progression. Tumor-derived cytokines and growth factors induce an altered hematopoiesis that modifies the myeloid cell differentiation process, promoting proliferation and expansion of cells with immunosuppressive skills, namely myeloid derived suppressor cells (MDSCs). MDSCs promote tumor growth not only by shaping immune responses towards tumor tolerance, but also by supporting several processes necessary for the neoplastic progression such as tumor angiogenesis, cancer stemness, and metastasis dissemination. Thus, MDSC targeting represents a promising tool to eliminate host immune dysfunctions and increase the efficacy of immune-based cancer therapies.

    Objective To explore the prognostic factors of non-small-cell lung cancer (NSCLC) patients with brain metastasis. Methods 122 NSCLC patients with brain metastasis from Jan 2007 to Dec 2012 were incorporated, and followed with death as the end. The influence factors of prognosis were retrospective analyzed. Kaplan-Meier method was used for survival analysis, the Log-rank test for single factor analysis,and Cox regression model for multiple factors analysis. Results The single-factor and multi-factor analysis showed that the influence factors of prognosis were age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation (P0.05). The average survival times of patients with palliative symptomatic treatment, simple whole brain radiotherapy, whole brain radiotherapy local lesion plus the amount of radiation, whole brain radiotherapy local lesion plus the amount of radiation combined with chemotherapy were (2.14 ±0.19) months, (7.28 ±0.60) months, (16.90 ±1.35) months, (17.7±1.12) months, 1 year survival rates were 0, 8.5%, 71.0%, 93.3%. Survival analysis showed that there was statistical significance among the four groups (P= 0.000). Conclusion The age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation are the prognosis factors in NSCLC patients with brain metastasis, therefore the treatment of these patients should be comprehensively analyzed.%目的:探讨非小细胞肺癌(NSCLC)脑转移患者预后的影响因素。方法回顾性分析2007年1月至2012年12月收治的122例NSCLC脑转移患者临床及随访资料,以死亡为结局,NSCLC脑转移患者预后的影响因素。以Kaplan-Meier方法进行生存分析,Log-rank检验进行单因素分析,Cox回归模型进行多因素分析。结果经单因素及多因素分析显示影响NSCLC脑

    Full Text Available BACKGROUND: Current prognostic gene signatures for breast cancer mainly reflect proliferation status and have limited value in triple-negative (TNBC cancers. The identification of prognostic signatures from TNBC cohorts was limited in the past due to small sample sizes. METHODOLOGY/PRINCIPAL FINDINGS: We assembled all currently publically available TNBC gene expression datasets generated on Affymetrix gene chips. Inter-laboratory variation was minimized by filtering methods for both samples and genes. Supervised analysis was performed to identify prognostic signatures from 394 cases which were subsequently tested on an independent validation cohort (n = 261 cases. CONCLUSIONS/SIGNIFICANCE: Using two distinct false discovery rate thresholds, 25% and <3.5%, a larger (n = 264 probesets and a smaller (n = 26 probesets prognostic gene sets were identified and used as prognostic predictors. Most of these genes were positively associated with poor prognosis and correlated to metagenes for inflammation and angiogenesis. No correlation to other previously published prognostic signatures (recurrence score, genomic grade index, 70-gene signature, wound response signature, 7-gene immune response module, stroma derived prognostic predictor, and a medullary like signature was observed. In multivariate analyses in the validation cohort the two signatures showed hazard ratios of 4.03 (95% confidence interval [CI] 1.71-9.48; P = 0.001 and 4.08 (95% CI 1.79-9.28; P = 0.001, respectively. The 10-year event-free survival was 70% for the good risk and 20% for the high risk group. The 26-gene signatures had modest predictive value (AUC = 0.588 to predict response to neoadjuvant chemotherapy, however, the combination of a B-cell metagene with the prognostic signatures increased its response predictive value. We identified a 264-gene prognostic signature for TNBC which is unrelated to previously known prognostic signatures.

    The status of resected lymph nodes in colon cancer determines prognosis and further treatment. The American Joint Committee on Cancer staging system has designated extramural nodules as nonnodal disease and classified them as extensions of the T category in the sixth edition and as site-specific tumor deposits in the seventh edition. Extracapsular lymph node extension is an established poor prognostic indicator in many cancers. Its significance in colon cancer has not been extensively investigated.

    Full Text Available Introduction: The aim of this study was to assess whether epidermal growth factor receptor (EGFR overexpression was a significant prognostic factor in clear cell renal cell carcinoma (CRCC and whether its prognostic significance was affected by immunohistochemical expression patterns. Materials and Methods: Immunohistochemistry was performed on 100 cases of CRCC using an antibody against EGFR. Tumors were grouped by nuclear grade (NG as low-NG (NG1, 2 or high NG (NG3, 4, and by pathological stage as localized (pT1, 2, or locally invasive (pT3, 4. Clinical disease was grouped by clinical stage as early stage (stage I, II, or late stage (stage III, IV. Evaluation of the EGFR overexpression was based on cytoplasmic (EGFR Cyt , and membranous (EGFR Mem staining. Results: EGFR Cyt correlated with high NG (P = 0.001, lymphovascular invasion (P = 0.028, regional lymph node involvement (P = 0.027, metastasis (P = 0.001, late stage (P = 0.003, cancer-specific death (P = 0.036, and was a predictor for disease-specific survival (P = 0.012 whereas EGFR Mem correlated with only local invasion (P = 0.021 and perirenal invasion (P = 0.009 and did not show any correlation with cancer-specific death or disease specific survival. Conclusion: Our findings suggest that EGFR overexpression is an important prognostic factor in CRCC, and its prognostic value differs significantly with respect to the location of EGFR immunostaining. This prognostic difference may give direction on the management and treatment of CRCC patients.

    Full Text Available Abstract Background Although prognostic biomarkers specific for particular cancers have been discovered, microarray analysis of gene expression profiles, supported by integrative analysis algorithms, helps to identify common factors in molecular oncology. Similarities of Ordered Gene Lists (SOGL is a recently proposed approach to meta-analysis suitable for identifying features shared by two data sets. Here we extend the idea of SOGL to the detection of significant prognostic marker genes from microarrays of multiple data sets. Three data sets for leukemia and the other six for different solid tumors are used to demonstrate our method, using established statistical techniques. Results We describe a set of significantly similar ordered gene lists, representing outcome comparisons for distinct types of cancer. This kind of similarity could improve the diagnostic accuracies of individual studies when SOGL is incorporated into the support vector machine algorithm. In particular, we investigate the similarities among three ordered gene lists pertaining to mesothelioma survival, prostate recurrence and glioma survival. The similarity-driving genes are related to the outcomes of patients with lung cancer with a hazard ratio of 4.47 (p = 0.035. Many of these genes are involved in breakdown of EMC proteins regulating angiogenesis, and may be used for further research on prognostic markers and molecular targets of gene therapy for cancers. Conclusion The proposed method and its application show the potential of such meta-analyses in clinical studies of gene expression profiles.

    Background and purpose: although gemistocytic astrocytomas are considered slow-growing tumors, they often behave aggressively and carry the least favorable prognosis among low-grade astrocytomas. The aim of this study is to evaluate the outcomes and prognostic factors of patients with incompletely excised gemistocytic astrocytomas irradiated postoperatively. Patients and methods: records of 48 patients with incompletely excised gemistocytic astrocytoma, irradiated between 1976 and 1998 at the department of radiation oncology, Maria Sklodowska-curie Memorial Cancer Center, Cracow, Poland, were reviewed. The total dose ranged from 50 to 60 Gy (mean: 59.35, median: 60 Gy) delivered in daily fractions of 2 Gy, 5 days a week. The treatment volume covered the residual tumor with a margin of 1-2 cm. Results: toxicity was acceptable. The overall actuarial survival rates at 5 and 10 years were 30% and 17%, respectively. Age and gender had an influence on overall survival by univariate and multivariate analysis (p < 0.05). Patients {<=} 35 years of age and female patients carried the best prognosis. Conclusion: in most patients with gemistocytic astrocytoma, combined surgery and postoperative radiotherapy result in only short-term survival. Older age is the most important unfavorable prognostic factor in patients with gemistocytic astrocytoma. (orig.)

  1. Survival and prognostic factors in 321 patients treated with stereotactic body radiotherapy for oligo-metastases

    International Nuclear Information System (INIS)

    Background and purpose: To establish a model to predict survival after SBRT for oligo-metastases in patients considered ineligible for surgical resection (SR) and radiofrequency ablation (RFA). Material and methods: Overall survival (OS) rates were estimated in 321 patients treated for 587 metastases with SBRT over 13 years. Patients were treated for a variety of metastasis types with colorectal cancer (CRC) being the most frequent (n = 201). Results: With a median follow-up time of 5.0 years, the median OS was 2.4 years (95% CI 2.3–2.7) and the survival rates were 80%, 39%, 23% and 12% at 1, 3, 5 and 7.5 years after SBRT, respectively. WHO performance status (PS) (0–1) (HR 0.49; p < 0.001), solitary metastasis (HR 0.75; p = 0.049), metastasis ⩽30 mm (HR 0.53; p < 0.001), metachronous metastases (HR 0.71; p = 0.02) and pre-SBRT chemotherapy (HR 0.59; p < 0.001) were independently related to favorable OS. Median OS rates were 7.5, 2.8, 2.5, 1.7 and 0.8 years with 0, 1, 2, 3, ⩾4 unfavorable prognostic factors, respectively. The treatment-related morbidity was moderate. However, three deaths were possibly treatment-related. Conclusion: Prognostic factors may predict long-term survival in patients with oligo-metastases treated with SBRT

    To determine whether the coefficient of variation (CV) of nuclear diameters can be used as a prognostic factor in papillary thyroid carcinoma, we reviewed fine needle aspiration smears with Riu's stain from 55 operated-on and pathologically verified cases with a median follow-up of 6.5 years. For each case we measured the nuclear diameters of 100 cancer cells by ocular micrometry and calculated the CV of the nuclear diameters. Then we correlated the CV with the clinical stage, recurrence and death. There was a positive correlation between the CV of the nuclear diameters and the clinical stage (r = .59, P less than .0001). Recurrent cases (n = 10) had a higher CV than did those without recurrence (n = 45) (18.04 +/- 4.1% [mean +/- SD] versus 13.2 +/- 2.7%, P less than .0005). All recurrent cases had a CV greater than 13%. The cases in which death occurred (n = 5) had a higher CV than did those with survival (n = 50) (20.1 +/- 4.9% versus 13.5 +/- 2.7%, P less than .0005). All cases in which death occurred had a CV greater than 15%. The extent of variation of nuclear diameters was one of the factors influencing prognosis in papillary thyroid carcinoma. It offers a prognostic adjunct to standard clinical and histologic analysis.

    Objective: The aim of this study was to investigate the correlation of STAT3 activation of tumor-associated macrophages (TAMs) and local cytokines (IL-β, TNF-α, TGF-β and IL-12) and prognostic factors in breast cancer. Methods: TAMs in 50 primary breast cancers and macrophages in 15 normal breasts were examined by immunohistochemistry. And STAT3 DNA-binding activity of TAMs in 33/50 primary breast cancers was measured by transcription factor DNA-binding ELISA. In addition, the concentrations of IL-β, TNF-α, TGF-β and IL-12 were measured in the 33 primary breast cancers extracts by ELISA. The correlation between STAT3 activity of TAMs and concentrations of IL-β, TNF-α, TGF-β and IL-12 were analyzed. The correlation between STAT3 activity of TAMs and conventional clinicopathologic parameters were also evaluated. Results: The macrophages density showed a significant increase in primary breast cancers compared to normal breasts. STAT3 DNA-binding activity of TAMs in breast cancer was significantly higher than that of monocytes/macrophages from peripheral blood of the patients. Furthermore, STAT3 activity of TAMs was correlated significantly with the levels of IL-β, TNF-α, TGF-β in breast cancer tissues. But an inverse association was observed between STAT3 activity of TAMs andIL-12. In addition, STAT3 activity of TAMs was higher in high histological type than in low histological type, and STAT3 activity of TAMs was higher in CerBb-2 positive than CerBb-2 negative. Conclusion: STAT3 activation of TAMs may be associate with increasing of IL-β, TNF-αand TGF-β and decreasing of IL-12 in breast cancer. STAT3 activation of TAMs may also be correlated with histological grade and CerBb-2 status of breast cancer.

  5. Concurrent cisplatin and radiotherapy for inoperable bladder cancer: long term results and prognostic predictors of local control and survival

    International Nuclear Information System (INIS)

    Therapeutic strategies for muscle invasive bladder cancer are currently evolving. A recent European randomized study has shown that neo-adjuvant chemotherapy does not improve the chance of cure or of conservative treatment. Concurrent chemotherapy and radiotherapy would provide better results but these is a need to identify by prognostic factors patients who may benefit from such a conservative strategy. Concurrent cisplatin and radiation therapy is a potentially locally curative treatment for 43 % of patients with muscle-invasive bladder cancer not candidates for radical surgery. Clinical T-stage and hydronephrosis have a significant and independent prognostic value on local control but appears not discriminant enough to select patients for conservative treatment. (authors)

    validation set, respectively. The prognostic impact was present both in patients with metastatic and nonmetastatic disease. The predictive value of the marker was investigated in stage II and III patients. In the training set, type IV collagen was prognostic both in the subsets of patients receiving and not...... receiving adjuvant antineoplastic therapy. However, in the validation set, the prognostic effect of the marker vanished when looking at patients who received adjuvant antineoplatic therapy (HR 0.90; 95% CI, 0.42-1.93) but was still present in the group not receiving adjuvant chemotherapy (HR 2.88; 95% CI, 1.......98-4.21). CONCLUSIONS: The results indicate clinical validity of type IV collagen as a prognostic biomarker in colorectal cancer, although the suggested predictive role of the marker should be validated.

    Full Text Available The definite prognostic role of p-STAT3 has not been well defined. We performed a meta-analysis evaluating the prognostic role of p-STAT3 expression in patients with digestive system cancers.We searched the available articles reporting the prognostic value of p-STAT3 in patients with cancers of the digestive system, mainly including colorectal cancer, gastric cancer, hepatocellular carcinoma, esophagus cancer and pancreatic cancer. The pooled hazard ratios (HRs with 95 % confidence intervals (95 % CIs of overall survival (OS and disease-free survival (DFS were used to assess the prognostic role of p-STAT3 expression level in cancer tissues. And the association between p-STAT3 expression and clinicopathological characteristics was evaluated.A total of 22 studies with 3585 patients were finally enrolled in the meta-analysis. The results showed that elevated p-STAT3 expression level predicted inferior OS (HR = 1.809, 95% CI: 1.442-2.270, P < 0.001 and DFS (HR = 1.481, 95% CI: 1.028-2.133, P = 0.035 in patients with malignant cancers of the digestive system. Increased expression of p-STAT3 is significantly related with tumor cell differentiation (Odds ratio (OR = 1.895, 95% CI: 1.364-2.632, P < 0.001 and lymph node metastases (OR = 2.108, 95% CI: 1.104-4.024, P = 0.024. Sensitivity analysis suggested that the pooled HR was stable and omitting a single study did not change the significance of the pooled HR. Funnel plots and Egger's tests revealed there was no significant publication bias in the meta-analysis.Phospho-STAT3 might be a prognostic factor of patients with digestive system cancers. More well designed studies with adequate follow-up are needed to gain a thorough understanding of the prognostic role of p-STAT3.

    Background Small for gestational age (SGA) infants are associated with a high rate of oligohydramnios, stillbirth and cesarean delivery. Among SGA patients there is a higher risk of neonatal complications, such as polycythemia, hyperbilirubinemia, and hypothermia. Additionally, the SGA infant is prone to suffer from major neurologic sequelae, as well as cardiovascular system disease, in later life. Proper monitoring and therapy during pregnancy are, therefore, of utmost importance. The present study aimed to investigate the influential and prognostic factors of SGA infants.Methods From January 2001 to June 2007, a total of 55 SGA neonatal infants were included in a study group. All were born at Peking Union Medical College Hospital, with regular formal antenatal examinations. In addition, a total of 122 cases of appropriate for gestational age (AGA) infants were bom at the same time and were registered into a control group. All cases were singleton pregnancies with detailed information of the maternal age, gravidity, parity, maternal height and weight, complications, uterine height and abdominal circumference, results from transabdominal ultrasonography between 32-38 gestational weeks, pregnancy duration, delivery manner, placenta, umbilical cord, and neonatal complications.Results Significant differences were observed in placenta weight and neonatal malformations between the study and control groups. Multivariate analysis revealed increased parity, maternal hyperthyroidism and hyperthyroidism history as risk factors. Fetal abdominal circumferences less than 30 and 32 cm at 32-38 gestational weeks respectively, as determined by ultrasonography, resulted in a Youden index of 0.62.Conclusions SGA infants were associated with a greater risk of smaller placentas and infant malformations. Increased parity, maternal hyperthyroidism, and a hyperthyroid history were risk factors for SGA infants. Fetal abdominal circumference less than 30 cm at 32 gestational weeks and less

    In order to define the prognostic factors for metastatic renal carcinoma, we reviewed 134 patients who were treated from 1971 through 1986. Survival rates were 72, 45, and 25% at 6, 12, and 18 months, respectively. Seventeen variables were tested using the logrank test. Improved survival was correlated with normal performance status, and an absence of fever, weight loss, hepatic metastasis, and lung metastasis (or, if lung metastasis was present, less than 2 cm in diameter and limited to one site), a disease-free interval, sedimentation rate less than 100, and renal surgery. Four variables retained significant value in the multivariate analysis: hepatic metastasis, lung metastasis, disease-free interval, and a variable combining the sedimentation rate and the weight loss (SWRL). Predictive survival rates based on these variables were calculated from the Cox model. Six subgroups of patients were identified. The estimation of survival is clinically of value for future phase II trials of chemotherapy in patients with adult metastatic renal carcinoma. PMID:3187293

    Idiopathic CD4+ lymphocytopenia (ICL) is a rare non–HIV-related syndrome with unclear natural history and prognosis. This prospective natural history cohort study describes the clinical course, CD4 T lymphocyte kinetics, outcome, and prognostic factors of ICL. Thirty-nine patients (17 men, 22 women) 25 to 85 years old with ICL were evaluated between 1992 and 2006, and 36 were followed for a median of 49.5 months. Cryptococcal and nontuberculous mycobacterial infections were the major presenting opportunistic infections. Seven patients presented with no infection. In 32, CD4 T-cell counts remained less than 300/mm3 throughout the study period and in 7 normalized after an average of 31 months. Overall, 15 (41.6%) developed an opportunistic infection in follow-up, 5 (13.8%) of which were “AIDS-defining clinical conditions,” and 4 (11.1%) developed autoimmune diseases. Seven patients died, 4 from ICL-related opportunistic infections, within 42 months after diagnosis. Immunologic analyses revealed increased activation and turnover in CD4 but not CD8 T lymphocytes. CD8 T lymphocytopenia (< 180/mm3) and the degree of CD4 T cell activation (measured by HLA-DR expression) at presentation were associated with adverse outcome (opportunistic infection-related death; P = .003 and .02, respectively).

    Abstract Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL. From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed. In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4. High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not

    We have recently shown that centrosomal protein 57 (CEP57) is overexpressed in a subset of human prostate cancers. CEP57 is involved in intracellular transport processes, and its overexpression causes mitotic defects as well as abnormal microtubule nucleation and bundling. In the present study, we further characterized the prognostic and functional role of CEP57 in prostate cancer. Unexpectedly, we found that high CEP57 expression is an independent prognostic factor for a more favorable biochemical recurrence-free survival in two large patient cohorts. To reconcile this finding with the ability of CEP57 to cause cell division errors and thus potentially promote malignant progression, we hypothesized that alterations of microtubule-associated transport processes, in particular nuclear translocation of the androgen receptor (AR), may play a role in our finding. However, CEP57 overexpression and microtubule bundling had, surprisingly, no effect on the nuclear translocation of the AR. Instead, we found a significant increase of cells with disarranged microtubules and a cellular morphology suggestive of a cytokinesis defect. Because mitotic dysfunction leads to a reduced daughter cell formation, it can explain the survival benefit of patients with increased CEP57 expression. In contrast, we show that a reduced expression of CEP57 is associated with malignant growth and metastasis. Taken together, our findings underscore that high CEP57 expression is associated with mitotic impairment and less aggressive tumor behavior. Because the CEP57-induced microtubule stabilization had no detectable effect on AR nuclear translocation, our results furthermore suggest that microtubule-targeting therapeutics used in advanced prostate cancer such as docetaxel may have modes of action that are at least in part independent of AR transport inhibition.

    To explore the preoperative utility of FDG PET for the diagnosis and prognosis in a retrospective breast cancer case series. In this retrospective study, 104 patients who had undergone a preoperative FDG PET scan for primary breast cancer at the UZ Brussel during the period 2002-2008 were identified. Selection criteria were: histological confirmation, FDG PET performed prior to therapy, and breast surgery integrated into the primary therapy plan. Patterns of increased metabolism were recorded according to the involved locations: breast, ipsilateral axillary region, internal mammary chain, or distant organs. The end-point for the survival analysis using Cox proportional hazards was disease-free survival. The contribution of prognostic factors was evaluated using the Akaike information criterion and the Nagelkerke index. PET positivity was associated with age, gender, tumour location, tumour size >2 cm, lymphovascular invasion, oestrogen and progesterone receptor status. Among 63 patients with a negative axillary PET status, 56 (88.9 %) had three or fewer involved nodes, whereas among 41 patients with a positive axillary PET status, 25 (61.0 %) had more than three positive nodes (P < 0.0001). In the survival analysis of preoperative characteristics, PET axillary node positivity was the foremost statistically significant factor associated with decreased disease-free survival (hazard ratio 2.81, 95% CI 1.17-6.74). Preoperative PET axillary node positivity identified patients with a higher burden of nodal involvement, which might be important for treatment decisions in breast cancer patients. (orig.)

    KRAS and BRAF mutations lead to the constitutive activation of EGFR signaling through the oncogenic Ras/Raf/Mek/Erk pathway. Currently, KRAS is the only potential biomarker for predicting the efficacy of anti-EGFR monoclonal antibodies (mAb) in colorectal cancer (CRC). However, a recent report suggested that the use of cetuximab was associated with survival benefit among patients with p.G13D-mutated tumors. Furthermore, although the presence of mutated BRAF is one of the most powerful prognostic factors for advanced and recurrent CRC, it remains unknown whether patients with BRAF-mutated tumors experience a survival benefit from treatment with anti-EGFR mAb. Thus, the prognostic or predictive relevance of the KRAS and BRAF genotype in CRC remains controversial despite several investigations. Routine KRAS/BRAF screening of pathological specimens is required to promote the appropriate clinical use of anti-EGFR mAb and to determine malignant phenotypes in CRC. The significance of KRAS/BRAF mutations as predictive or prognostic biomarkers should be taken into consideration when selecting a KRAS/BRAF screening assay. This article will review the spectrum of KRAS/BRAF genotype and the impact of KRAS/BRAF mutations on the clinicopathological features and prognosis of patients with CRC, particularly when differentiating between the mutations at KRAS codons 12 and 13. Furthermore, the predictive role of KRAS/BRAF mutations in treatments with anti-EGFR mAb will be verified, focusing on KRAS p.G13D and BRAF mutations.
