Discrepancy amongst clinical examination (CE), ultrasonography (USG), mammography (MG), pathological examination (PE), and magnetic resonance imaging (MRI) has been reported.  But few studies have evaluated changes in breast tumor size from the operating table to the laboratory.<br/><br/>Objectives and Methods:  A prospective study was designed to assess the intra-operative (IO) tumor size in 29 patients of breast cancer presenting to a tertiary care center in Delhi, and to compare it with CE, USG, and PE. <br/><br/>Observations and Results: Twenty-nine patients (mean age: 47 years), presenting with invasive duct carcinoma (stage IIIA: 31%, stage IIB: 28%), were included in the study. Comparison with mean IO (4.2 cm) revealed that both USG and PE underestimated tumor size by a mean of 0.35 cm (8.4 %), and 0.45 cm (10.7%) respectively, in most patients. CE tended to overestimate size by 0.82 cm (19.8%). All 3 modalities showed statistically significant correlation with IO (maximum Pearson¡¯s correlation co-efficient for PE=0.937, p<0.001 R2 =0.877, maximum for PE). Two-way analysis of variance revealed mean difference in size to be statistically significant (p=0.000) only between CE and IO.  <br/><br/>Discussion: Formalin processing causes changes in tumor dimensions in the breast, causing reduction in tumor size. It may also have a bearing on the assessment of surgical margins in breast conservation surgery. Immediate postoperative measurement of the specimen is ideal. Protocol for specimen fixation should be standardized.<br/>]]></description></item><item><title>A Phase II Study of Thalidomide and Temozolomide in Patients With Brain Metastases From Malignant Melanoma. Lymphopenia Correlates With Response</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/ecancer.2008.91</link><pubdate>Fri, 15 Aug 2008 00:00:00 GMT</pubdate><description><![CDATA[BACKGROUND: CNS metastases develop in nearly half of patients with advanced melanoma and in 15-20 % CNS is the first site of relapse. Median overall survival is short, ranging from 2 to 4 months, and 1-year survival is only 10 to 15 %. THA has been shown to have both antiangiogenetic and immunomodulating effects. TMZ is an oral alkylating agent with an excellent oral bio-availability and it is highly lipophilic with an ability to penetrate the blood-brain barrier. TMZ and THA in combination were tested in patients with brain metastases from malignant melanoma (MM).<br/><br/>METHODS: Between June 2004 and February 2007 patients with measurable metastatic melanoma in progression and PS < 1 received TMZ in a dose of 150 mg/m2 qd for 7 days, followed by 7 days off therapy and THA in 200 mg qd, both orally administered. Concomitant treatment with steroids was allowed. PBMCs were collected from the last 14 consecutive patients for evaluation of immune parameters. <br/><br/>RESULTS: 40 screened patients were eligible and evaluable for response and 39 were evaluable for toxicity. 25 patients had asymptomatic and 15 symptomatic brain metastases. The toxicity was primarily grade 1-2 with no grade 4 or treatment related deaths. Four patients had tromboembolic events grade 3. One pt obtained a CR and 5 PR in the CNS, while 2 had CR and 4 PR outside CNS. Overall response rate was 17.5%. We found a significant positive correlation between lymphopenia and objective response.<br/><br/>CONCLUSIONS: The combination treatment was well tolerated but with more frequent thromboembolic events compared to single drug TMZ or THA. The treatment demonstrated activity in CNS as well as outside CNS. The correlation between lymphopenia and objective response needs further investigation.]]></description></item><item><title>Defeating Cancer With Antidepressants</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/ecancer.2008.88</link><pubdate>Thu, 21 Aug 2008 00:00:00 GMT</pubdate><description><![CDATA[Prostaglandins are ephemeral, infinitesimal signalers self-regulating every cell in the body, including those subserving mood and immunity. At first they were perceived as a master switch, but now are believed to regulate every component of cellular microanatomy and physiology, including those of the organelles, cytoskeleton, proteins, enzymes, nucleic acids and mitochondria. Prostaglandins are responsible, paradoxically, for cell function and dysfunction. Excessive prostaglandin synthesis depresses immune function and may induce cancer. An ideal anticancer agent would inhibit prostaglandins in such a manner as to shut down the pathogenesis of cancer. In this article I will show that antidepressants have such properties.]]></description></item><item><title>Syzygium Cumini Inhibits Growth and Induces Apoptosis in Cervical Cancer Cell Lines: A Primary Study</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/ecancer.2008.83</link><pubdate>Thu, 21 Aug 2008 00:00:00 GMT</pubdate><description><![CDATA[Cervical cancer is common among women in the Indian subcontinent and the incidences and death rates are gradually increasing over the years. Several dietary phytochemicals have been reported to have growth inhibitory and apoptotic effect on HeLa and other cervical cell lines. In this study, using Hoechst 33342 staining, MTT, Annexin V-FLUOS/PI  and TUNEL assays we demonstrated that Syzygium cumini extract inhibits the growth and induces apoptosis in HeLa and SiHa cervical cancer cell lines in a dose and time dependent manner. The phytochemical, its mode of action, and safety issues are yet to be determined.]]></description></item><item><title>A Randomised Prospective Study of Extended Tocopherol and Pentoxifylline Therapy, in Addition to Carbogen, in the Treatment of Radiation Late Effects</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.81</link><pubdate>Mon, 9 Jun 2008 00:00:00 GMT</pubdate><description><![CDATA[Purpose: Pentoxifylline (PTX) and tocopherol (Vitamin E) are antioxidants previously shown to be useful in combination in the treatment of late radiation induced toxicity. The purpose of this study was to investigate the benefit of combination therapy with carbogen pentoxifylline and tocopherol in the mitigation of late radiation effects. As the optimal duration of PTX and tocopherol treatment has not been fully established, we studied short versus extended treatment duration.   <br/> <br/>Methods: We conducted a phase II prospective randomised study of short versus prolonged treatment with pentoxifylline (800 mg) and tocopherol (1000 IU) orally once daily in patients with grade 3 toxicity post radical radiotherapy. In addition, all 18 patients received inhaled carbogen (95% oxygen + 5% CO2) over 90 minutes, 5 days per, week for 3 weeks. The primary endpoint was improvement in maximum Lent-Soma toxicity scores.<br/>	<br/>Results: Maximum Lent-Soma scores improved in six of the eighteen patients (response rate 33%). The proportion of patients responding to treatment in the prolonged treatment arm B was more than double than in the shorter arm A, but this did not reach statistical significance (p  0.321). Two patients who had prolonged treatment (arm B) had complete resolution of their symptoms which was maintained at 2 and 3 years follow up. <br/>           <br/>Conclusions: We recommend prolonged treatment for 12 months, with PTX and tocopherol in combination with carbogen therapy, in the management of late radiation effects.<br/>]]></description></item><item><title>Changes in Cancer Incidence and Mortality in England & Wales and a comparison of cancer deaths in the Major Developed Countries by Age and Sex 1979-2002 in context of GDP Expenditure on Health</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.80</link><pubdate>Mon, 28 Jul 2008 00:00:00 GMT</pubdate><description><![CDATA[Background<br/>The successful treatment of cancer is a major health and political issue in England & Wales and also in the Major Developed Countries (MDC). All Malignancy deaths by age and gender are analysed to determine how successful the MDC were in reducing cancer deaths between 1979-2002 within the context of the each nations Gross-Domestic-Product-Expenditure-on-Health’ (GDPEH) over the period.<br/><br/>Method<br/>Incidence rates of new cancers in England & Wales are examined for 1979-80 to 2003-04 to highlight extent of the problem. Set in the context of GDREH for each MDC 1980-2002 as an indicator of how each nation has responded to the challenge of cancer. The changing cancer mortality rates for England & Wales are compared with each MDC by age and sex using WHO All Malignancies mortality rates over the period 1979-81 to 2000-02.  Chi square tests are used to compare outcomes between England & Wales with each MDC.<br/><br/>Results<br/>1] Men’s All Age malignancy incidence in England & Wales rose 48% and women’s 51% with notable rises for females aged 15-34 and 55-74years.<br/>2] Every MDC increased GDPEH substantially UK up to 9.3% but remains 8th of ten MDC and still below the MDC average (9.85%).<br/>3] England & Wales men’s average (15-74years) deaths were 3rd highest in 1979-81 but fell to 8th by 2000-02 declining significantly more than 7 other MDC.<br/>England & Wales women’s average (15-74 years) rates were highest in 1979-81 and in 2000-02 but declined significantly more than most MDC in every age band from 35-74 years.<br/>4] Most MDC countries men’s rates declined significantly more than their women’s except Japan and Spain but the improvements in men’s cancer death were not matched in women’s rates especially the 35-54’s. <br/> Conclusions: Rising incidence poses problems for every MDC but especially for England & Wales as does the relatively low Anglo-Welsh GDPEH whilst poorer women’s results should be a matter of concern for most MDC. The reductions in cancer deaths reflects well on all front-line services indicating what can be achieved with improved GDDPEH but should not obscure the challenge of the rising incidence of cancer.]]></description></item><item><title>Management training for hospital administrators: Sentinel lymph-node biopsy under local anaesthetic for carcinoma of the breast - organisational and economic impact</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.74</link><pubdate>Fri, 15 Feb 2008 00:00:00 GMT</pubdate><description><![CDATA[Sentinel lymph-node biopsy under local anaesthetic for carcinoma of the breast: organisational and economic impact.<br/><br/>This study compares sentinel lymph-node biopsy carried out at the time of removal of the primary breast tumour, under general anaesthetic, with sentinel lymph-node biopsy carried out under local anaesthetic prior to the main operation.<br/><br/>It compares the total cost of the two treatment approaches, in terms of average income and of their impact on the subsequent programming of operations and hence on waiting lists and income.]]></description></item><item><title>The effect of transdermal estradiol or oral conjugated oestrogen and fenretinide versus placebo on haemostasis and cardiovascular risk biomarkers in a randomised breast cancer chemoprevention trial</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/ecancer.2008.67</link><pubdate>Wed, 6 Feb 2008 00:00:00 GMT</pubdate><description><![CDATA[Introduction:<br/>We have previously reported the favourable effect of transdermal estradiol (E2), relative to oral conjugated equine oestrogen (CEE), on ultrasensitive C-reactive protein after 12 months of treatment in a retinoid-placebo controlled two-by-two randomised breast cancer prevention trial (ref). Here we investigate the changes in lipids and clotting profile in patients of the same trial. <br/><br/>Methods and Results: <br/>Recent postmenopausal women were randomised to either oral CEE 0.625 mg/d and placebo (n=55), CEE and fenretinide 200 mg/d (n=56), transdermal E2 50 µg/d and placebo (n=59), or E2 and fenretinide 200 mg/d (n=56). Sequential medroxyprogesterone acetate 10 mg/d was given in each group. After 12 months there was a statistically significant effect of the route of administration of hormone replacement therapy (HRT) on fibrinogen levels the median percent change being -5.7% with CEE and -1.1% with E2 (P=0.012). Total cholesterol decreased in all arms (P<0.0001). HDL-C decreased significantly with transdermal E2 (P=0.006) compared to oral CEE and with fenretinide relative to placebo (P<0.001). Triglycerides exhibited an opposite modulation by HRT route, with a 21.4% median increase with oral CEE and an 8.6% reduction with transdermal E2 (P<0.0001). Antithrombin-III showed a 4% borderline significant reduction in the fenretinide arm relative to placebo, irrespective of HRT administration route (P=0.055). <br/><br/>Conclusions:<br/>Our data indicate that transdermal E2 may be preferable to oral CEE based on its safer cardiovascular risk profile. Fenretinide modified some cardiovascular risk biomarkers and confirmed a safer profile compared to other retinoids.]]></description></item><item><title>Post-genomic clinical trials - the perspective of ACGT</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.66</link><pubdate>Mon, 21 Jan 2008 00:00:00 GMT</pubdate><description><![CDATA[Advancing Clinico Genomic Trials (ACGT) is an EU co-funded project that develops open-source semantic and grid-based technologies in support of post genomic clinical trials in cancer research. It addresses clinicians bio-researchers as well as software developers providing an open platform where novel and powerful services can be offered and put to use by practitioners in the field.<br/><br/>This article discusses the ACGT's approach to collecting and dealing with genomic data. It also looks at the ACGT's ultimate objective providing a unified technological infrastructure which will facilitate the seamless and secure access and analysis of multi-level clinical and genomic data enriched with high-performing knowledge discovery operations and services. <br/><br/>By doing so it is expected that the influence of genetic variation in oncogenesis will be revealed the molecular classification of cancer and the development of individualised therapies will be promoted and finally the in-silico tumour growth and therapy response will be realistically and reliably modelled.]]></description></item><item><title>Full Dose Intraoperative Radiotherapy With Electrons (ELIOT) During Breast  Conserving Surgery - Experience with 1246 Cases</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.65</link><pubdate>Tue, 26 Feb 2008 00:00:00 GMT</pubdate><description><![CDATA[Abstract<br/>Background. Previous studies showed that after breast conserving surgery for breast cancer , Radiotherapy may be applied to the portion of the breast where the primary tumor was removed (partial breast irradiation - PBI) avoiding the irradiation of the whole breast. We developed a procedure of PBI consisting in a single high dose of radiotherapy of 21Gy with electrons equivalent to 58-60Gy in fractionated doses, delivered during the surgical session by a mobile linear accelerator, positioned close to the operating bed.<br/>Patients and methods From July 1999 to December 2006, 1246 patients with primary carcinoma less than 2.5 cm in diameter mostly over 48 years were treated with Electron IntraOperative Radiotherapy (ELIOT) at a single dose of 21Gy.<br/>Results. After a follow-up from 0.3 to 94.7 months (median 26), 24 patients (1.9 %) showed a local recurrence and 22 developed distant metastases. 16 patients died, 7 for breast carcinoma and 9 for others causes. The 5 years crude survival was 96.5%. Six cases (0.5%) developed serious breast fibrosis which resolved in two-three years. Other 40 patients suffered for mild fibrosis. Cosmetic results were good.<br/>Conclusions. ELIOT is a safe method for treating conservatively operated breasts, avoids the long period of postoperative radiotherapy greatly improving the quality of life and reduces the cost of Radiotherapy. ELIOT reduces radiation to normal surrounding tissues and deep organs. Results on short-term and middle-term toxicity are good. Data on local control are encouraging.]]></description></item><item><title>Institutional guidelines and ongoing studies in management of liver tumours: The experience of the European Institute of Oncology</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.64</link><pubdate>Fri, 2 May 2008 00:00:00 GMT</pubdate><description><![CDATA[Background:<br/>An institutional task force on Upper Gastrointestinal Tumours is active at the European Institute of Oncology (EIO).

Cases were classified into 4 cohorts 1: all cycles delivered at full dose and on time 2: one single dose reduction or dose delay 3: >1 dose reduction or dose delay 4: <2 cycles of chemotherapy delivered. <br/><br/>Results: 484 eligible cases were identified (cohort 1: n = 268 2: n= 88 3: n= 89 4: n= 39). Slight imbalances in lymph node status (p=0.05) and adjuvant hormonal therapy (p=0.05) were observed between the cohorts. 55% (267/484) of the patients had node-positive disease and 33% (158/484) were ER+. 45% of cases had a reduction in DI. With a median follow-up of 9.6 years, there were no significant differences in relapse-free survival (p=0.94), breast cancer-specific survival (p=0.87) or overall survival (p=0.86) between the 4 cohorts. Outcomes were independent of hormone receptor status.<br/><br/>Conclusions: Although toxicity related reductions in the DI of adjuvant AC chemotherapy for early stage breast cancer are common, they did not appear to significantly impact on clinical outcomes in this population-based cohort of women with stage I-II breast cancers. <br/>]]></description></item><item><title>Does LigaSure(TM)  Reduce Fluid Drainage in Axillary Dissection? A Randomised Prospective Clinical Trial.</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.61</link><pubdate>Thu, 29 Nov 2007 00:00:00 GMT</pubdate><description><![CDATA[Background – Axillary lymph node dissection (ALND) is an integral part of breast cancer treatment. It is required in about 60% of patients. The placement of a drain in the axilla after an operation is current surgical practice. Short surgical stay programs increase operating efficiency and reduce medical care costs, without compromising quality of care. LigaSureTM is a new haemostatic device that  uses bipolar energy to seal vessels. The aim of this study was to determine whether axillary dissection with LigaSureTM reduces  the time of wound drainage, the duration of surgical intervention and the volume of drainage after treatment. <br/>Patients and Methods – This study is a prospective randomized controlled trial. 100 women with breast cancer who needed axillary dissection were randomized into the LigaSureTM or conventional axillary dissection group. Level I to III lymph node dissection was performed. A closed suction drain was always placed in the axilla and removed after 6-8 days or when fluid amount was < 60 cc in the previous 24 hours.<br/>Results – There were no significant differences between the two groups when considering the duration of surgical procedure: average duration was 70.7 ± 24.66 minutes for LigaSureTM patients, while in the conventional dissection group the mean was 70.6 ± 22.47 minutes (p=0.98). Total amount of drained fluid was 624.49 cc in the LigaSureTM axillary dissection group and 792.96 in the conventional ALND group; this difference did not achieve statistical significance (p=0.09);  the duration of draining was also similar with no statistical difference (p=0.15).<br/>Conclusions – The present study did not show clear advantages in LigaSureTM use for ALND, although it represents a good haemostatic device, especially in abdominal surgery.<br/><br/>Keywords – breast carcinoma; breast cancer surgery; axillary dissection; seroma; drain; haemostasis; LigaSure.]]></description></item><item><title>Technique of Sentinel Lymph Node Biopsy and Lymphatic Mapping During Laparoscopic Colon Resection for Cancer</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.60</link><pubdate>Thu, 15 Nov 2007 00:00:00 GMT</pubdate><description><![CDATA[Background: The utility of lymphnode mapping to improve staging in colon cancer is still under evaluation. Laparoscopic colectomy for colon cancer has been validated in multicentric trials. This study assessed the feasibility and technical aspects of lymphnode mapping in laparoscopic colectomy for colon cancer. Methods. Forty-two patients with histologically proven colon cancer were studied from January 2006 to September 2007. Exclusion criteria were: advanced disease (clinical stage III), rectal cancer, previous colon resection and contraindication to laparoscopy. Lymphnodal status was assessed preoperatively by computed tomography (CT) scan and intraoperatively with the aid of laparoscopic ultrasound. Before resection, 2-3 ml of Patent Blue V dye was injected subserosally around the tumor. Colored lymphnodes were marked as sentinel (SN) with metal clips or suture and laparoscopic colectomy with lymphadenectomy completed as normal. In case of failure of the intraoperative procedure an ex vivo SN biopsy was performed on the colectomy specimen after resection. Results. A total number of 904 lymphnodes were examined, with a median number of 22 lymphnodes harvested per patient. The SN detection rate was 100%, an ex vivo lymphnode mapping was necessary in 4 patients. Eleven (26.2%) patients had lymphnodal metastases and in 5 (45.5%) of these patients, SN was the only positive lymphnode. There were two (18.2%) false negative SN. In three cases (7.1%) with aberrant lymphatic drainage, lymphadenectomy was extended. The accuracy of SN mapping was 95.2% and negative predictive value was 93.9%. Conclusions: Laparoscopic lymphatic mapping and SN removal is feasible in laparoscopic colectomy for colon cancer. The ex vivo technique is useful as salvage technique in case of failure of the intraoperative procedure. Prospective studies are justified to determine the real accuracy and false negative rate of the technique.]]></description></item><item><title>Response to Neo-Adjuvant Chemotherapy for Colorectal Cancer Liver Metastases: A Key for Improving Survival?</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2007.58</link><pubdate>Tue, 16 Oct 2007 00:00:00 GMT</pubdate><description><![CDATA[Hepatic resection in metastatic disease from colorectal cancer offers the best chance in selected cases for long-term survival. Neoadjuvant chemotherapy (NACT) has been advocated in some cases initially deemed irresectable, with few reports of the efficacy of such a strategy and the influence of the response to chemotherapy on the outcome of radical hepatic resection. Methodology: Between December 1995 and May 2005, 27 patients with colorectal liver metastases, (7 males, 20 females, mean age: 58¡À 8 years; range: 40-75) were treated with neoadjuvant chemotherapy. A 7 year survival analysis was performed. Chemotherapy included mainly 5-fluorouracil, leucovorin and either oxaliplatin or irinotecan for a median of 8 courses. <br/><br/>Sixteen patients (59%) had synchronous and 11 (41%) metachronous metastases. During pre-operative chemotherapy tumour regression occurred in 10 cases (37%); stable disease (SD) in a further 10 patients (37%) and progressive disease (PD) developed in 7 cases (26%). The 5 year overall survival for NACT responders was 64% and only 15% for non-responders (p=0.044).<br/><br/>The response to chemotherapy is likely to be a significant prognostic factor affecting survival after liver resection for cure.]]></description></item><item><title>Elevated breast cancer risk among mothers of a population-based series of 2668 children with cancer</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2008.57</link><pubdate>Thu, 17 Jan 2008 00:00:00 GMT</pubdate><description><![CDATA[Aims: Although a previous study found high risk of breast cancer in mothers of children with soft tissue sarcomas, breast cancer risks in mothers of other childhood cancer largely remain unknown. The etiology is not fully understood. The present study explored this excess by varying type of childhood solid cancer and formulated a hypothesis.<br/><br/>Methods: Mothers of 2668 children with solid tumours included in the Manchester Children’s Tumour Registry, 1954-1996 were traced and followed up to 31st December 2000 through the UK National Health Service Central Register. Standardised Incidence Ratio(SIR), P-values and 95% confidence intervals were calculated from age and calendar year-specific female breast cancer incidence rates for England and Wales.<br/><br/>Results: There was a significant excess of breast cancer in mothers overall(SIR=1.3,95%CI=1.0-1.5) mainly due to mothers of children with rhabdomyosarcoma (RMS) (SIR=2.2, 95%CI=1.0-4.0), skin cancer(SIR=7.9, 95%CI=2.9-17.1), and central nervous system tumours(SIR=1.2, 95%CI=0.9-1.8). Maternal breast cancer risk was associated with late age at birth of the index child and male sex and young age at diagnosis in the index child. Risk was highest in the 10 years following the birth of the index. The pattern was seen most strongly in mothers of children with embryonal RMS.<br/><br/>Conclusion: There are excesses of breast cancer in mothers of children with solid tumours in general and specifically in RMS, skin and CNS. There appears to be a temporal relationship between certain tumours in children and breast cancer in their mothers, suggesting a origin of their respective pregnancy. We propose a mother-fetal<br/>interaction mechanism to explain this association.]]></description></item><item><title>Developing a European Grid Infrastructure for Cancer Research: Vision, Architecture, and Services</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2007.56</link><pubdate>Fri, 21 Sep 2007 00:00:00 GMT</pubdate><description><![CDATA[Life sciences are currently at the centre of an informational revolution. The nature and amount of information now available open directions of research that were once in the realm of science fiction. During this informational revolution, the data gathering capabilities have greatly surpassed the data analysis techniques. Data integration across heterogeneous data sources and data aggregation across different aspects of the biomedical spectrum, therefore, is at the centre of current biomedical and pharmaceutical R&D. <br/>This paper reports on original results of the ACGT integrated project focusing on the design and development of a European Biomedical Grid infrastructure in support of multicentric, post genomic clinical trials on Cancer. Post-Genomic clinical trials (CTs) use multilevel clinical and genomic data and advanced computational analysis and visualization tools to test hypothesis in trying to identify the molecular reasons for a disease and the stratification of patients in terms of treatment. <br/>The paper provides a presentation of the needs of users involved in post-genomic CTs, and presents indicative scenarios which drive the requirements of the engineering phase of the project. Subsequently, the initial architecture specified by the project is presented and its services are classified and discussed.  A range of such key services, including the Master Ontology on Cancer which lies at the heart of the integration architecture of the project, are presented. Special efforts have been taken to describe the methodological and technological framework of the project, enabling the creation of a legally compliant and trustful infrastructure.  <br/>Finally, a short discussion of the forthcoming work is included and the potential involvement of the cancer research community in further development or utilization of the infrastructure is described.]]></description></item><item><title>[18F] FDG uptake: pay attention to candies</title><link>http://www.ecancermedicalscience.com/view-article.asp?doi=10.3332/eCMS.2007.48</link><pubdate>Wed, 15 Aug 2007 00:00:00 GMT</pubdate><description><![CDATA[[18F]Fluorodeoxyglucose ([18F]FDG) is a positron emission radiotracer whose biodistribution is similar to glucose. The similar biodistribution of [18F]FDG and glucose in human body justify the fasting condition of, at least, 6 hours required to perform a [18F]FDG Positron Emission Tomography ([18F]FDG PET) study.<br/><br/>In human studies, FDG PET images, in either the fasting state or the glucose-loaded state, have demonstrated that [18F]FDG uptake in tumor is decreased, and thus the PET image quality is impaired when plasma glucose levels are increased. All these results suggest that patients should fast before FDG PET studies and their plasma glucose concentration needs to be considered when assessing tumour glucose metabolism. Minn reported contrasting data about the difference behaviour of FDG in lymphomatous disease, reporting that insulin does not induce major changes in glucose uptake of lymphomatous tissue.<br/><br/>We report two cases of lymphoma patients that underwent [18F]FDG PET/Computed Tomography ([18F]FDG PET/CT) for chemotherapy response evaluation. Both [18F]FDG PET/CT scans were negative about the known lesions but showed increased and diffuse FDG uptake in muscles. This led us to investigate better the fasting condition founding the assumption of glucose. [18F]FDG PET/CT was repeated 3-4 days after and pathological uptake in the lymphomatous lesions was revealed, in both cases.<br/><br/>We demonstrate that euglycemic state is a necessary condition that have to be tested before [18F]FDG administration as the knowledge of the timing of fasting that should be, at least, of 6 hours.]]></description></item></channel></rss>
