Joint Modeling of Tumor Size and Time-to-Event
… term with time is used to describe the change in tumor size and an accelerated failure time frailty model with either weibull or exponential distribution is used to describe the overall survival time. The survival and longitudinal components are linked through random effects with appropriate …

Clinical and Pathologic Characteristics of Hepatocellular Carcinoma following Resection according to the Tumor Size
A tumor size of hepatocellular carcinoma (HCC) has been known to be an important prognostic factor after resection and it is considered to be closely correlated with vascular invasion of HCC. We aimed this study to elucidate the outcomes according to some previously studied size criteria and the …

Application of fuzzy linear regression models for predicting tumor size of colorectal cancer in Malaysia's Hospital
… to find the best models to predict the size of tumor colorectal cancer. The quality of life among CRC patients which is to detect the early CRC stage is still very poor, not implemented and divulged as a nationwide programme. The main objective of this study is to determine the best …

Comparative Analysis of Radiologically Measured Size and True Size of Renal Tumors
PURPOSE: We evaluated the effects of different tumor conditions on discrepancy between radiologically measured size and true size of renal tumors. MATERIALS AND METHODS: The data from 238 patients who underwent radical or partial nephrectomy for a renal tumor at our institution were reviewed. …

Relation between F-18 FDG Uptake of PET/CT and BRAFV600E Mutation in Papillary Thyroid Cancer
… uptake value (SUVmax) of the primary tumor and clinicopathologic variables. RESULTS: The BRAFV600E mutation was detected in 82.2% (139/169). In all subjects, the BRAFV600E mutation and tumor size were independently related to SUVmax by multivariate analysis (P = 0.048 and P < 0.001, …

Two stages hybrid model of fuzzy linear regression with support vector machines for colorectal cancer
… However, the factor and symptoms to predict tumor size of colorectal cancer still ambiguous and not clear. The problem in using a linear regression will arise when uncertain data and not precise data were presented. Since the fuzzy set theory‟s concept can deal with data not to a precise …

Course of clinical response during primary systemic therapy with a dose-dense 4 cycles regime of adriamycin and docetaxel in patients with operable cancer of the breast
… chemosensitivity test. One possibility to assess tumor response is the consideration and analysis of clinical parameters such as palpation of the tumor size. <br>Up to now, little is known about typical courses of tumor shrinkage or growth under PST. <br>The results of this dissertation support …

Prognostic significance of preoperative neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with non-metastatic clear cell renal cell carcinoma
… correlated with symptom presentation (p=0.008), tumor size (p=0.022), T stage (p=0.004), neutrophil count (p<0.001), lymphocyte count (p<0.001), recurrence at follow-up (p=0.006). Preoperative PLR was significantly correlated with symptom presentation (p<0.001), lymphocyte count (p<0.001), …

Pretreatment Serum CYFRA 21-1 Level Correlates Significantly with Survival of Cervical Cancer Patients: A Multivariate Analysis of 506 Cases
… of Gynecology and Obstetrics (FIGO) stage, large tumor size, lymph node metastasis, and deep stromal invasion. In the stepwise Cox regression analysis, large tumor size > 4cm was an independent prognostic factor for disease-free survival (OR, 3.110; [95% CI, 1.588-6.093], P=0.001) and overall …

Inter-alpha-trypsin inhibitor heavy chain H4 as a diagnostic and prognostic indicator in patients with hepatitis B virus-associated hepatocellular carcinoma
… Cox regression analysis showed that large tumor size (>5 cm) was independently associated with overall survival (hazard ratio 5.894, 95% confidence interval 1.373–25.300, P = 0.017). A Kaplan-Meier survival analysis showed significantly worse survival among HCC patients with both low ITIH4 …

Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence.
… (MFH) and in 140 mixed STS. In the MFH series, tumor size and Ki-67, as the only IHC marker, provided independent prognostic information. In the mixed STS series whole-tumor sections were used and TMA was performed in the peripheral tumor growth zone. Whole-tumor sections facilitated assessment …

Body mass index and response to neoadjuvant chemotherapy in Korean breast cancer
… age, weight, height. The kind of chemotherapy , tumor size at before and after NAC, operative procedure, postoperative pathological tumor size, lymph node status, nuclear grade , histologic grade , hormone receptor status, epidermal growth factor receptor expression was analyzed. And disease-free …

INFLUENCE OF GENOTYPE, PROTEIN-CALORIE RESTRICTION AND THEIR INTERACTION UPON RSV-INDUCED TUMORS IN CHICKENS
… upon Rous sarcoma virus (RSV)-induced tumor development in chickens. Two genetic systems were used. The first involved an inbred line and a noninbred line of chickens. The second utilized F2 generation progeny from a cross of lines 6-1 and 15-1, highly inbred lines of White Leghorns …

The aim of this work was to evaluate ILT in breast cancer with respect to technique, changes in tissue immunocompetent cells and effect on prognosis. The method is dependent on accurate assessment of the tumor, and another aim …
