Results: Patients with pT3 disease had much higher PCA3 score (median = 48.8, range =7.5-269.0) than pT2 patients (median = 18.7, range = 4.0-79.9), p = 0.02. Spearman analysis showed that PCA3 score significantly correlated with total tumor volume (n = 72, R = 0.38, P , .01). Patients with larger tumor volume (,2.0 cc) have significantly (p = 0.01) higher PCA3 score (median = 47.6, range = 7.5 - 269.0) compared to patients with smaller tumor volume (0.5 - 2.0 cc: median=17.5; ,0.5 cc: median=18.7). Adjusted by other pre-surgical variables (age, race, serum PSA, clinical stage, biopsy grade, etc.), stepwise multivariate logistic regression analyses showed that PCA3 score was an independent predictor of pT3 prostate cancer (p = 0.01) and for a total tumor volume of ,0.5 cc (p = 0.04). This is the first report of a urine assay predicting pathologic stage in prostate cancer ...

PURPOSE: Retrospective studies indicate that larger tumour volume is a strong prognostic indicator for poor tumour control after (chemo)radiotherapy for laryngeal cancer. The impact of tumour volume on the outcome of patients treated within a prospective study comparing accelerated radiotherapy (AR)+/-carbogen breathing and nicotinamide (ARCON) was investigated. METHODS AND MATERIALS: Of 345 patients with cT2-4 laryngeal cancer, pre-treatment computed tomography (CT) scans of 270 patients were available for tumour volume calculation. Contouring of the primary tumour and involved lymph nodes was reviewed by one experienced head and neck radiation oncologist. Kaplan-Meier plots were used for analysis of outcome. RESULTS: Of 137 AR and 133 ARCON patients, 57 and 80 versus 56 and 77 patients had glottic and supraglottic tumours, respectively. A correlation between primary tumour volume and T-stage was observed (Rs=.51, P,.01). In both treatment arms no correlation was detected between the primary ...
The model presented here is based on the model we described earlier (10), but we improved it by rewriting the entire set of differential equations to make the model quantitatively more precise, to recognize 3 rather than 2 cell types, and most importantly by including the effect of antigen shedding, which was not included in the original model.. An important advantage of this model is that it can handle tumors of any size and yields total tumor volume information dynamically while considering only one representative unit of a modest and constant size. Because the model assumes that the total cell density is uniform and unchanged, this is not a good model for poorly vascularized, necrotic regions of the tumor. However, the efficacy of RIT is an issue for well vascularized, rapidly growing tumor; it may be less important for slowly growing, necrotic regions of a tumor. Also, although the cell density is assumed constant for any one tumor model, one can study the effect of density changes by doing ...
These types of tumours are often non cancerous in nature. It is very much similar to the cancer since the growth come along due to the result of abnormal cells. But unlike any other cancer tumour, it is simply unable to spread the other kinds of areas of the body and it will not impact to any nearby tissues. It carries enough which stays at the point of its growth. However, in terms of fatality, these tumours are not lethal or unhealthy though the location of this tumour may cause problems. The mass of the tumour would add pressure over the primary nerve along with the main artery, which compresses the brain content and hence even the benign tumour can be problematic. Some of the probable causes to this tumour include traumatic injury over the tumour location along with the chronic inflammation, which gives undetected infection ...

Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled with 5.9 kBq/mL 18F-FDG to characterize normal lung tissues as a phantom. The PET/CT images of the phantom were acquired at rest. Then, the barrel was moved periodically to simulate breathing while acquiring PET/CT data. Volume recovery coefficient (VRC) was applied to evaluate the accuracy of ITVs. For statistical analysis, paired t-test and analysis of variance were applied. Results: The VRCs ranged from 0.74 to 0.98 and significantly varied among gross tumor volumes for delineating ITV (P|0.01). In two-dimensional PET scans, the motion distance did not affect VRC (P|0.05), whereas VRC decreased with increasing
Prognostic value of tumor burden in nasopharyngeal carcinoma Chuanben Chen,1,2 Zhaodong Fei,1,2 Chaoxiong Huang,2 Jianming Ding,1,2 Lisha Chen1,2 1Department of Radiation Oncology, Fujian Cancer Hospital, Fujian Medical University Cancer Hospital, Fuzhou, Fujian, People’s Republic of China; 2Provincial Clinical College, Fujian Medical University, Fuzhou, Fujian, People’s Republic of China Background: The prognostic value of primary tumor volume (TV) in nasopharyngeal carcinoma (NPC) has been confirmed. However, studies of the prognosis value of tumor burden, including TV and nodal volume (NV), have been relatively infrequent. Therefore, the aim of this study was to evaluate the prognostic value of tumor burden in NPC patients treated with intensity-modulated radiotherapy.Methods: Receiver operating characteristics curves were generated to determine rational cutoff points for TV and NV. The volumes identified included 12.5, 25.0, and 50.0 mL, and 0, 12.5, and 25 mL, respectively.
There are however some points that could work in favor. Patients proposed for Phase I typically have a serious tumor burden, so that % changes in tumor burden can be interpreted as being on a common scale (as compared to % changes of smaller tumor burden, which may be argued to be oversensitive to clinically irrelevant changes).. The doses or regimens that are proposed to be measured with the intent of showing an acceptable toxicity profile are the ones that will be used for Phase II and likely also Phase III. In other words, we can look for the therapeutic window as early as Phase I.. Some data will be shown on the possibility ‐ at least at an experimental level - to explore percent changes in tumor measurements as a quantitative variable, which should better enable correlative attempts as described above. Another point to consider is the potential comparative nature of early data. What do we mean by this? In late Phase trials, randomization is a necessity for valid comparison by minimizing ...

The adaptive trial design of this advanced Phase II study incorporates (i) a dosing schedule based on the patients estimated tumor burden and not on standard dosing per kilogram body weight or body surface area, and (2) a tumor response evaluation process that is unique to the manner in which osteosarcoma responds favorably to therapy, i.e., with necrosis and increasing calcification in metastatic tumors and decreased glucose utilization using PET-CT imaging studies.. Twenty to thirty patients will receive Rexin-G at either Dose Level 1 or 2. Patients will be assigned a dose level based on the estimated tumor burden as measured by PET-CT imaging studies. Estimated tumor burden is measured by multiplying the sum of the longest diameters of target lesions in cm by 10e9 cancer cells. If the tumor burden is less than 10 billion cells, the patient will be assigned to Dose Level 1, if the tumor burden is greater than 10 billion cells, the patient will be assigned to Dose Level 2.. *Treatment Cycle ...
The involvement of interleukin (IL-) 6 in malignant disease has been investigated in a variety of different malignancies. To evaluate whether serum IL-6 is a useful disease marker in metastatic malignant melanoma (MMM), we studied the time course of endogenous IL-6 secretion in 41 patients treated with cisplatinum, IL-2, and IFN-alpha. Furthermore, the relationship of endogenous IL-6 concentrations to the tumor burden and/or the clinical response was also evaluated. The baseline serum IL-6 levels were significantly higher in patients with MMM than in the control group (P = 0.002). When tumor burden was taken into consideration, we found that IL-6 levels were higher in patients with high tumor burden than in patients with low tumor burden. During treatment in the whole patient population, a higher serum IL-6 level was observed in nonresponding as compared to responding patients at days 7 (P = 0.0005), 21 (P = 0.002), and 35 (P = 0.009). The follow-up of serum IL-6 in patients with MMM according ...
Removing a tumor from your brain is hard to do because, very often, brain tumors do not have boundaries that are easy for your surgeon to find. In many cases, the surgeon cant tell exactly where the tumor begins or ends. The surgeon usually can remove most of your tumor by looking at the MRI images that were taken of your brain before surgery. However, the surgeon does not have any good way to tell if the entire tumor has been removed or not. Removing the entire tumor is very important because leaving tumor behind may allow it to grow back which could decrease your chances of survival.. It is possible to detect tumor cells by making them glow with a specific color of light (a process called fluorescence). This can be done by having you take the drug, ALA, before your surgery. ALA is a molecule that already exists in the cells of your body. Once enough of it is in your body, it gets converted into another molecule named PpIX. If blue light is shined on a tumor that has enough PpIX, it will glow ...
Our later investigations confirm our previous results.. 1. It is possible to increase markedly the effect of substances inhibiting tumor growth by using certain combinations of these substances which, when given alone, have some effect on tumor growth.. 2. Immunity acquired against the effect of these substances depends partly upon an active immunization of the tumor cells themselves against the action of these substances, and this immunity is transmitted to the following generations of tumor cells.. 3. The immunity against the substances inhibiting tumor growth is, as far as we have investigated the problem, specific.. 4. Our later experiments provide a more secure basis for the additional and more general conclusions which we mentioned tentatively in our previous paper.. ...
There are a few visual tests that may be performed to detect if the tumor is benign. Typically, benign tumors have a regular shape, regular edges, an even color and will not be very large. However, there are malignant tumors that may look like a benign tumor, especially during the initial stages. The benign tumors may be diagnosed by performing a biopsy. A small sample will be taken from the tumor and will be analyzed. The pathologist may establish if the cells are cancerous or benign. If the cells are benign, they resemble in structure with the cells that are found near the tumor. The benign cells will be inactive, do they wont divide or multiply like the malignant cells. Cancerous cells are differently structured and will be identified under the microscope. Malignant tumors will have an increased amount of chromosomes. ...

One of the most important factors in classifying a tumor as benign or malignant is its invasive potential. If a tumor lacks the ability to invade adjacent tissues or spread to distant sites by metastasizing then it is benign, whereas invasive or metastatic tumours are malignant.[1] For this reason, benign tumours are not classed as cancer.[2] Benign tumors will grow in a contained area usually encapsulated in a fibrous connective tissue capsule. The growth rates of benign and malignant tumors also differ; benign tumors generally grow more slowly than malignant tumors. Although benign tumors pose a lower health risk than malignant tumors, they both can be life-threatening in certain situations. There are many general characteristics which apply to either benign or malignant tumors, but sometimes one type may show characteristics of the other. For example, benign tumors are mostly well differentiated and malignant tumors are often undifferentiated. However, undifferentiated benign tumors and ...
