A total of 40.76 million inpatient medical records were used to generate the outcome variables, while the explanatory variables were from hospital information database and China Health and Family Planning Statistical Yearbook and literatures.Results: Inpatient expenditure pattern for cancer(IEPC) varied largely across provinces, ranging from 3.03% to19.61%. The major sources of variability were from the differences of hospital level and number of beds. There was homogeneity within a province, while heterogeneity between the provinces. Rising one level of the hospital led to the increase of 0.475 natural logarithm units of IEPC averagely. The number of beds increasing 1,000 each made the natural logarithm of IEPC increase one unit averagely.Conclusions: Our study showed that a considerable proportion of IEPC variation could be explained by the differences of hospital level and number of beds. It implied that it is possible to estimate disease-specific ratio of inpatient expense taking into account key influencing factors in China. Furthermore, this study is an input to economic and financial analyses and provides evidence for future study on the national economic burden of cancer.展开更多

The Raman shifts obtained at the Indiana University Bloomington (IUB) and Indiana University-Purdue University Indianapolis (IUPUI) laboratories have been processed for diagnosing various types of cancer tissues. The objective of this research is to distinguish between cancerous and non-cancerous tissues. Small size tissue samples have been processed, seeking the minimum size tissue that can be diagnosed via Raman spectroscopy. The tests have been conducted on nearly 20 human tissues. A Matlab program has been written following Parzen-Window classifier to recognize the Raman shift pattern for various types of cancer tissues, including breast cancer, kidney, and Gyn-Uterus. A software visual model has been used for data processing. Unique signals for breast and kidney tumors have been obtained. The approach followed in this paper shows promise for early cancer detection in humans.展开更多

Methods: The anthropometric assessment was carried out according to the WHO standard and eating habits were assessed using a questionnaire food frequency. The dietary inflammatory index (eDII) was calculated based on the frequency of consumption of anti- and pro-inflammatory foods. Results: 178 colorectal cancer cases and 178 controls were included, age over 50 years (81.7%). 38.2% of CRC individuals were smokers or former smokers and 69.1% were overweight, 15.7% had type II diabetes and 41% had hypertension. The consumption of bread and white rice (OR 1365.8;p < 0.001), meat processed up to twice a week (OR 227.35;p = 0.001) and low fruit intake (OR 40.569;p = 0.039) increased the risk for CRC development. The eDII greater than 0 and 3 increases the risk of CRC for women (OR 55.83;95% CI 6.53 - 477.16;p < 0.001) and men (OR 66.75;95% CI 19.05 - 233;p Conclusions: In the south of Brazil, the Western diet pattern was related to the diagnosis of CRC, in addition to the male gender, smoking and overweight. In an unprecedented way for the Brazilian population, we associate eDII with the risk of CRC.展开更多

The study included 268 cases and 536 controls with non-neoplastic diseases. The foods and beverages in the food-frequency questionnaire were included in a factor analytic model. This method retained three factors which were labeled as the drinker, red meat, and prudent patterns. The model explained 60% of the variance. Whereas the red meat and drinker patterns were directly associated with the risk of cervical cancer (OR for red meat pattern 1.79, 95% CI 1.12-2.86), on the other hand, the prudent pattern was inversely associated with cervical cancer (OR 0.60, 95% CI 0.38-0.93). To our knowledge, this study was the first one using factor analysis in order to elucidate the role of the diet in relation with cervical cancer.展开更多

Methods: We retrospectively reviewed patients’ files to define TNBC patients’ characteristics, predictive and prognostic factors, pattern of recurrence and survival. Results: 965 cases were identified. 147 patients (15.2%) were TNBC. 71.1% patients were premenopausal. T2, T3, T4 tumors represented 46.1%, 32% and 14.1%, respectively. N0, N1, N2, N3 disease represented 18.5%, 50.9%, 27.8% and 2.8%, respectively. Stages II, III & IV constituted 34.1%, 44.2% and 15.5%, respectively. 31.5% patients received neoadjuvant chemotherapy with 17.7% complete pathological response. 19.5%, 35.9%, 44.6% patients had unknown, ≤20 and >20 Ki67, respectively. Among non-metastatic patients (n = 108), 21.3% patients developed relapse with median time to relapse of 11 months. 78.3% of them had visceral (88.3% lung) metastasis, 13% bone metastasis, 21.7% brain metastasis and 13% LRR. There is significantly high risk of relapse in patients with large tumor size [T4: 66.75%, T3: 22.9%, T2: 16.7%, T1: 0% (p = 0.002)], positive LNs [N3: 100%, N2: 37.9%, N1: 15.1%, N0: 4.3% (p 0.001)] and Ki67 [>20: 31.6% versus 10.8% for Ki67 ≤ 20 (P = 0.007)]. Multivariate analysis revealed only T4 and N2-3 were significantly associated with high probability for relapse (P = 0.022 & 0.038). The 3-year DFS and OS were 73.2% and 75% respectively. For metastatic patients (n = 20), the m PFS was 7 months and m OS 1.5 years. Conclusion: Our data confirms the aggressive nature of TNBC with significant risk of relapse for patients with large tumor and positive lymph nodes. Maintenance metronomic capecitabine, neoadjuvant/adjuvant immunotherapy could be beneficial for non-metastatic patients. Lungs and brain were the most common sites of distant failure with poor survival that necessitates administration of molecular biomarkers (BRCA mutations, PD-L1 expression and microsatellite instability) for patients’ selection for novel targeted therapy.展开更多

The goal of this study was to understand treatment patterns, biomarker testing practices, treatment adherence, and the clinical and economic outcomes associated with chemotherapy for metastatic disease. Methods and Materials: We retrospectively examined electronic health records of patients with metastatic CRC who initiated chemotherapy between 01 January 2007 and 30 June 2011, with follow-up to 30 June 2012. Parameters analyzed included demographics and clinical characteristics, treatment patterns, clinical outcomes, and health care resource utilization. Results: In the analysis, 756 patients were included;median age was 61 years (55% male) at start of first line therapy. The most commonly used regimens in the first, second, and third line were FOLFOX + bevacizumab (46%), FOLFIRI + bevacizumab (23%), and irinotecan + cetuximab (23%) respectively. Adherence to guidelines decreased with increasing line of therapy. When assessed by treatment backbone categories in the third line, outcome measures including overall survival (OS), and time to treatment discontinuation (TTD) were not statistically different between groups. In the multivariable model, body mass index (BMI), performance status, and KRAS were significant predictors of survival. Conclusions: This study provides insight into patterns of care and outcomes of mCRC patients for the aforementioned time period. As treatment options for mCRC evolve, it is valuable to understand the continuum of care to help inform future treatment among candidates for continued therapy.展开更多

Methods: A total of 79 LD-SCLC patients were treated with a combination of chemotherapy and chest radiotherapy. Radiotherapy of the tumour and the pathological lymph nodes was performed either as 45 Gy twice-daily or 46 - 50 Gy once-daily. 18Fluro-2-deoxy-D-glucose (18FDG)-PET/CT was performed in 35 patients as part of the staging procedure. Results: With a median follow-up time of 17 months 6% developed isolated loco-regional failures while 57% developed distant metastases. No isolated regional failures were seen. Median overall survival was 22 months. Patients staged with a 18FDG-PET/CT had a significantly lower incidence of distant failures and a significantly improved overall survival compared with patients only staged with a CT scan (p = 0.03) (median overall survival of 34 versus 17 months, respectively). Conclusion: The pattern of failure showed a high risk of distant metastases but a low incidence of isolated loco-regional failures. Patients staged with an 18FDG-PET/CT had a significantly lower incidence of distant failures and better overall survival, indicating that 18FDG-PET could be beneficial in patients with LD-SCLC before deciding on treatment regimen.展开更多

It means that the frequent sequence pattern is high. Another measure is confidence. All of the confidence values are 1. Then, the last performance measure is lift ratio at average more than 1. It means that the composed sequence items in the pattern has high dependency and relatedness. Futhermore, the selected patterns are applied as biomarker with accuracy as 100%.
文摘Background: Triple negative breast cancer (TNBC) tends to present aggressively with rapid progression and poor survival. Methods: We retrospectively reviewed patients’ files to define TNBC patients’ characteristics, predictive and prognostic factors, pattern of recurrence and survival. Results: 965 cases were identified. 147 patients (15.2%) were TNBC. 71.1% patients were premenopausal. T2, T3, T4 tumors represented 46.1%, 32% and 14.1%, respectively. N0, N1, N2, N3 disease represented 18.5%, 50.9%, 27.8% and 2.8%, respectively. Stages II, III & IV constituted 34.1%, 44.2% and 15.5%, respectively. 31.5% patients received neoadjuvant chemotherapy with 17.7% complete pathological response. 19.5%, 35.9%, 44.6% patients had unknown, ≤20 and >20 Ki67, respectively. Among non-metastatic patients (n = 108), 21.3% patients developed relapse with median time to relapse of 11 months. 78.3% of them had visceral (88.3% lung) metastasis, 13% bone metastasis, 21.7% brain metastasis and 13% LRR. There is significantly high risk of relapse in patients with large tumor size [T4: 66.75%, T3: 22.9%, T2: 16.7%, T1: 0% (p = 0.002)], positive LNs [N3: 100%, N2: 37.9%, N1: 15.1%, N0: 4.3% (p 0.001)] and Ki67 [>20: 31.6% versus 10.8% for Ki67 ≤ 20 (P = 0.007)]. Multivariate analysis revealed only T4 and N2-3 were significantly associated with high probability for relapse (P = 0.022 & 0.038). The 3-year DFS and OS were 73.2% and 75% respectively. For metastatic patients (n = 20), the m PFS was 7 months and m OS 1.5 years. Conclusion: Our data confirms the aggressive nature of TNBC with significant risk of relapse for patients with large tumor and positive lymph nodes. Maintenance metronomic capecitabine, neoadjuvant/adjuvant immunotherapy could be beneficial for non-metastatic patients. Lungs and brain were the most common sites of distant failure with poor survival that necessitates administration of molecular biomarkers (BRCA mutations, PD-L1 expression and microsatellite instability) for patients’ selection for novel targeted therapy.
文摘Raman spectroscopy was used to distinguish the serums from lung cancer patients and healthy people, through spectral pretreatment method combined with pattern recognition methods including principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA), un-correlated linear discriminant analysis (ULDA), etc. Through the comparisons of the results, it can be found that ULDA and LDA combined with multiple scatter correction (MSC) pretreatment method successfully distinguish the patients of lung cancer and healthy people. The method has academic significance and promising clinical application value.
文摘Introduction: Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the third leading cause of cancer deaths in the United States. The goal of this study was to understand treatment patterns, biomarker testing practices, treatment adherence, and the clinical and economic outcomes associated with chemotherapy for metastatic disease. Methods and Materials: We retrospectively examined electronic health records of patients with metastatic CRC who initiated chemotherapy between 01 January 2007 and 30 June 2011, with follow-up to 30 June 2012. Parameters analyzed included demographics and clinical characteristics, treatment patterns, clinical outcomes, and health care resource utilization. Results: In the analysis, 756 patients were included;median age was 61 years (55% male) at start of first line therapy. The most commonly used regimens in the first, second, and third line were FOLFOX + bevacizumab (46%), FOLFIRI + bevacizumab (23%), and irinotecan + cetuximab (23%) respectively. Adherence to guidelines decreased with increasing line of therapy. When assessed by treatment backbone categories in the third line, outcome measures including overall survival (OS), and time to treatment discontinuation (TTD) were not statistically different between groups. In the multivariable model, body mass index (BMI), performance status, and KRAS were significant predictors of survival. Conclusions: This study provides insight into patterns of care and outcomes of mCRC patients for the aforementioned time period. As treatment options for mCRC evolve, it is valuable to understand the continuum of care to help inform future treatment among candidates for continued therapy.
文摘Background: The purpose of this study was to evaluate the use of 18FDG-PET/CT in staging procedure, the pattern of failure and survival in patients with small-cell lung cancer limited disease (LD-SCLC) undergoing chemo-radiotherapy. Methods: A total of 79 LD-SCLC patients were treated with a combination of chemotherapy and chest radiotherapy. Radiotherapy of the tumour and the pathological lymph nodes was performed either as 45 Gy twice-daily or 46 - 50 Gy once-daily. 18Fluro-2-deoxy-D-glucose (18FDG)-PET/CT was performed in 35 patients as part of the staging procedure. Results: With a median follow-up time of 17 months 6% developed isolated loco-regional failures while 57% developed distant metastases. No isolated regional failures were seen. Median overall survival was 22 months. Patients staged with a 18FDG-PET/CT had a significantly lower incidence of distant failures and a significantly improved overall survival compared with patients only staged with a CT scan (p = 0.03) (median overall survival of 34 versus 17 months, respectively). Conclusion: The pattern of failure showed a high risk of distant metastases but a low incidence of isolated loco-regional failures. Patients staged with an 18FDG-PET/CT had a significantly lower incidence of distant failures and better overall survival, indicating that 18FDG-PET could be beneficial in patients with LD-SCLC before deciding on treatment regimen.
