Hypermethylation of E‐cadherin is an independent predictor of improved survival in head and neck squamous cell carcinoma
Authors: Marsit Carmen J. , Posner Marshall R. , McClean Michal D. , Kelsey Karl T. 
Published: August 2008

AbstractBACKGROUND.The loss of E‐cadherin (ECAD) protein expression has been linked to aggressive head and neck squamous cell carcinoma (HNSCC). Promoter hypermethylation of the cadherin 1, type 1 (CDH1) gene (encoding ECAD) is 1 mechanism by which this protein can be inactivated, although this epigenetic alteration of the gene has not been linked conclusively to poorer patient outcome and, in fact, may be associated with better patient prognosis.METHODS.The authors investigated the prevalence of CDH1 promoter hypermethylation in a population‐based case series of 340 primary HNSCC tumors using methylation‐specific polymerase chain reaction. They also studied the association between CDH1 hypermethylation and patient demographic characteristics using multivariate analysis and examined the impact of CDH1 hypermethylation on patient survival using both univariate and multivariate methods.RESULTS.Hypermethylation of CDH1 was significantly more prevalent (P < .03) among individuals with a low smoking history independent of whether they were seropositive for human papillomavirus type 16 (HPV‐16). Patients who had tumors with CDH1 hypermethylation had significantly better overall survival compared with patients who had tumors without hypermethylation (P < .02; log‐rank test). This effect was independent of HPV‐16 status and demonstrated a significant hazard ratio of 0.5 (95% confidence interval, 0.3‐0.9) in a model that controlled for HPV‐16 serology, age, sex, and tumor stage.CONCLUSIONS.The current results suggested that hypermethylation of CDH1 occurs more commonly in patients with HNSCC who are low smokers, suggesting that an additional factor may be driving this epigenetic alteration. Clinically, CDH1 hypermethylation may hold powerful prognostic potential in addition to that observed with HPV serology, and the authors concluded that it should be pursued in additional studies.

Irinotecan and uridine diphosphate glucuronosyltransferase 1A1 pharmacogenetics
Authors: Deeken John F. , Slack Rebecca , Marshall John L. 
Published: August 2008

AbstractPharmacogenetic research indicates a relationship between a polymorphism in the gene encoding uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) and irinotecan inactivation, in that degradation of SN‐38, the active metabolite of irinotecan, correlates inversely with the number of TA repeats in the TATA element of the UGT1A1 promoter region. Individuals who are homozygous for the UGT1A1*28 allele (7 repeats) may exhibit reduced degradation of SN‐38 and increased probability of severe toxicities. Clinical study results, as reported in the literature, have not been uniform, however, in showing a relation between genotype and the development of toxicities. Even when correlations are statistically significant, confidence intervals are wide, rendering assessment of individual risk difficult at best. Irinotecan labeling recommends testing for the UGT1A1*28 allele and reducing irinotecan dosing in patients who are positive to reduce the likelihood of dose‐limiting neutropenia only, but not diarrhea. Importantly, both dose‐limiting neutropenia and diarrhea are dependent on numerous known and unknown factors, such as the specific regimen used, duration of therapy, doses, cycle of treatment, and complexities of irinotecan pharmacodynamics and pharmacokinetics, including other key enzymes and drug transporters. Guidance on how to modify irinotecan dosing or how to incorporate the impact of multiple variables into clinical decision‐making does not exist. Furthermore, pharmacogenomic test results at this time can only provide an estimate of risk for subsets of populations rather than a risk‐benefit estimate for an individual. Consequently, these test results are supplementary to clinical judgment, which requires assessing multiple variables that contribute to phenotype to arrive at individual dosing decisions.

Liposarcoma
Authors: Engström Katarina , Bergh Peter , Gustafson Pelle , Hultborn Ragnar , Johansson Helena , Löfvenberg Rickard , Zaikova Olga , Trovik Clement , Wahlström Ola , Bauer Henrik C.F. 
Published: August 2008

AbstractBACKGROUND.The aim was to study the clinicopathological characteristics, treatment, and outcome of liposarcoma in an unselected, population‐based patient sample, and to establish whether treatment was according to the Scandinavian Sarcoma Group (SSG) treatment guidelines.METHODS.The SSG Pathology Board reviewed 319 liposarcoma cases reported between 1986 and 1998. After the review, 237 patients without metastasis were analyzed for local recurrence rate in relation to surgical margins, radiotherapy, occurrence of metastasis, and survival.RESULTS.Seventy‐eight percent of the patients were primarily operated on at a sarcoma center, 45% with wide margins. All patients operated on outside the center had nonwide margins. Low‐grade lesions constituted 67% of cases. Despite nonwide surgery, only 58% of high‐grade lesions were treated with postoperative radiotherapy. The risk of local recurrence after nonwide surgery, without irradiation, was 47% for high‐grade lesions. The estimated 10‐year, local recurrence‐free and metastasis‐free survival in the low‐grade group was 87% and 95%, respectively. In the high‐grade group, it was 75% and 61%, respectively. Independent adverse prognostic factors for local recurrence were surgery outside a sarcoma center and histological type dedifferentiated liposarcoma. For metastases, they were old age, large tumor size, high grade, and histological type myxoid liposarcoma with a round cell component. Radiotherapy showed significant effect on local recurrence rate for the same grade and margin.CONCLUSIONS.Patients with liposarcoma should be treated at specialized centers. Postoperative radiotherapy decreases the local recurrence rate. To maintain quality and provide support for further trials, reporting to quality registers is crucial.

Spectroscopic Diagnostics of Pulsed Microwave Plasmas used for Nanocrystalline Diamond Growth
Authors: Bénédic Fabien , Duten Xavier , Syll Ousmane , Lombardi Guillaume , Hassouni Khaled , Gicquel Alix 
Published: August 2008

AbstractIn this paper, we report emission and broadband absorption spectroscopy measurements carried out in order to characterize the pulsed process used for nanocrystalline diamond (NCD) film deposition using an Ar/H2/CH4 gas mixture. Both the gas temperature and C2 total density are determined from the C2 (D1Σu+ − X1Σg+) Mulliken system. Time‐resolved and time‐averaged measurements are performed in order to probe the influence of the pulse repetition rate for a duty cycle of 50%, keeping a constant time‐averaged microwave power. Time‐resolved fast imaging enables the two‐dimensional examination of plasma ignition and expansion during the microwave pulses. The time‐averaged gas temperature and C2 density depend weakly on the pulse repetition rate, with values always in the range 3600–4000 K, and around 1 × 1014 cm−3, respectively. These values are close to those measured for a continuous discharge, which suggests that the changes of the NCD growth process should be linked to the time evolution of the gas temperature and key‐species density. The time evolution of the gas temperature is characteristic of a heating rate of approximately 100 K ms−1, which is very long compared to conventional H2/CH4 microwave discharges. Variation of 1000 K is thus obtained during the microwave pulse at 50 Hz, which implies important changes in the plasma composition during the microwave period. Also, the time‐resolved fast imaging of the plasma discharge for a 50 Hz pulse repetition rate shows that the plasma volume and intensity evolve almost all over the microwave pulse. A considerable time evolution of some plasma characteristics such as absorbed microwave power or species density and gas temperature radial profiles is then expected. Finally, since the C2H2 → C2 → C conversion channels are mainly driven by the gas temperature, the increase of the gas temperature during the microwave pulse seems to lead first to the production of the C2 molecule, while C atoms are produced at the end of the microwave pulse when the gas temperature is high enough. Such time evolution of the plasma chemistry should influence the NCD deposition process in pulsed mode.
Formation of Continuous Nanocrystalline Diamond Layers on Glass and Silicon at Low Temperatures

Published: August 2008

AbstractNanocrystalline diamond thin films are grown on silicon and glass substrates by microwave plasma (MP)CVD from a gas mixture of methane and hydrogen at low substrate temperatures. The initial stages of diamond growth, i.e., i) the growth of individual nanometer‐sized crystals and clusters, and ii) coalescence into a continuous layer, are investigated by diverse analytic techniques. Atomic force microscopy (AFM) measurements reveal nearly unchanging surface roughness up to 40 min. X‐ray photoelectron spectroscopy (XPS) measurements detect changing of the surface composition from the very beginning of the growth process. The rapid carbon increase is assigned to the enlarging of the grown crystals and clusters. Scanning electron microscopy (SEM) images indicate a possible lateral growth type. The found dependences indicate that a two‐dimensional growth mode takes place at low substrate temperatures. Grown nanocrystalline diamond films are optically transparent in a wide spectral range, and exhibit a high refractive index of 2.34.
