Radical retropubic prostatectomy in Hispanic patients
Authors: Gomez Pablo , Manoharan Muruqesan , Sved Paul , Kim Sandy S. , Soloway Mark S.
Published: March 2004

BACKGROUND

Hispanics are the largest minority group in the U.S. Most studies assessing race as a predictor of biochemical disease recurrence after radical retropubic prostatectomy (RRP) have focused on African‐American patients. To the authors' knowledge, little has been published to date regarding radical prostatectomy in Hispanic patients. Hispanics represent 29% of the patients in the current study. The authors analyzed the presentation and outcome of Hispanic males managed with radical prostatectomy.

METHODS

In the current study, 1163 RRPs were performed. Patients were categorized by ethnicity as Hispanics, white non‐Hispanics, African‐Americans, and other ethnicities. African‐American and other minority group patients were excluded from the analysis because of the small number in the current series. A comparative analysis of Hispanics and white non‐Hispanics was performed.

RESULTS

RRP was performed in 1163 patients. Two hundred seven Hispanic and 518 white non‐Hispanic patients met the study criteria. The mean follow‐up was 46.9 months. Twenty‐three percent of the Hispanic patients received neoadjuvant therapy. RRP Gleason scores of 2–6, 7, and 8–10 were found in 45% of patients, 38% of patients, and in 17% of patients, respectively. Lymph node metastases were present in 3%, seminal vesicle invasion in 13%, and extraprostatic extension in 23% of Hispanic patients. Adjuvant hormonal therapy was administered to 6% of the Hispanic patients. The biochemical disease recurrence rate was 12%. The mean time to biochemical disease recurrence was 29.7 months. A comparison between the Hispanic and the white non‐Hispanic groups showed no significant differences in the analyzed variables.

CONCLUSIONS

Hispanic patients managed with radical prostatectomy for prostate carcinoma were found to have similar presentation, pathologic findings, and outcome as the white non‐Hispanic patients. Cancer 2004. © 2004 American Cancer Society.
The fragile genes FHIT and WWOX are inactivated coordinately in invasive breast carcinoma
Authors: Guler Gulnur , Uner Aysegul , Guler Nilufer , Han Shuang‐Yin , Iliopoulos Dimitrios , Hauck Walter W. , McCue Peter , Huebner Kay
Published: March 2004

BACKGROUND

FHIT and WWOX are a tumor suppressor and a candidate suppressor that encompass the FRA3B and FRA16D fragile sites at chromosomes 3p14.2 and 16q23.3–24.1, respectively. Reduced or absent Fhit expression has been reported in two‐thirds of invasive breast tumors in association with adverse prognostic factors. Loss of 16q has been reported frequently in low‐grade, invasive breast tumors.

METHODS

Expression of Fhit and Wwox was evaluated by immunohistochemical staining in 97 archived breast carcinoma specimens. Expression levels were analyzed for correlations with each other, as well as with various patient and tumor characteristics.

RESULTS

Reduced Fhit and Wwox expression in tumors was observed in 54.6% and 63.2% of specimens, respectively. Fhit and Wwox expression were correlated strongly (P = 0.001). Reduced Fhit staining was seen more frequently in premenopausal patients (P = 0.010), estrogen receptor (ER)‐negative or scantly ER‐positive tumors (P = 0.058 borderline), high‐grade tumors (P = 0.005), and tumors with metastases (P = 0.041). Reduced Wwox staining was more common in tumors with less favorable ER status (P = 0.033). Wwox expression in normal tissue was reduced in 32.9% of specimens, especially in patients with higher stage disease (P = 0.033). Severely reduced Wwox staining (extent < 10%) in normal tissue was found only in postmenopausal women, but reduced Wwox staining (11–75%) was more common in premenopausal women (P = 0.012). Tumor status, lymph node status, and intensity of Fhit expression in tumors were related independently to survival (P = 0.003, P < 0.001, and P = 0.046, respectively).

CONCLUSIONS

The strong correlation observed between Fhit and Wwox expression was consistent with the common elevated susceptibility of fragile sites to DNA damage. Reduced Fhit expression is associated with adverse prognostic factors. The current results suggest that Wwox also has an important and complex association with steroid hormone expression and breast carcinogenesis. Cancer 2004. © 2004 American Cancer Society.
High‐dose methotrexate pharmacokinetics and outcome of children and young adults with osteosarcoma
Authors: Crews Kristine R. , Liu Tiebin , Rodriguez‐Galindo Carlos , Tan Ming , Meyer William H. , Panetta J. Carl , Link Michael P. , Daw Najat C.
Published: March 2004

BACKGROUND

High‐dose methotrexate (HDMTX) is used frequently in combination regimens that include nephrotoxic chemotherapy. The authors evaluated the impact of factors such as age and prior nephrotoxic agents on MTX pharmacokinetics in children and young adults with osteosarcoma and examined whether MTX pharmacokinetic parameters were associated with outcome.

METHODS

The authors evaluated MTX pharmacokinetics in 140 patients who were treated with 1083 courses of HDMTX on 3 consecutive studies of multiagent chemotherapy at a single institution. The influence of MTX pharmacokinetics on the outcome of 107 patients with localized disease was examined.

RESULTS

Mean peak MTX concentrations ≥ 1000 μM were achieved in 135 patients (96%). MTX clearance was decreased after cisplatin therapy (P= 0.01), after cisplatin in combination with ifosfamide therapy (P< 0.0001), and after MTX therapy (P= 0.003). In patients with localized osteosarcoma, a higher mean MTX area under the curve, a higher mean peak concentration of MTX, a longer mean time above a threshold concentration (500 μM), and a lower mean MTX clearance were associated with lower probability of event‐free survival (EFS). Patients who had a mean peak MTX plasma concentration > 1500 μM were found to have a worse outcome (estimated 5‐year EFS, 58.5% ± 6.7%) compared with patients who had a mean peak concentration ≤ 1500 μM (estimated 5‐year EFS, 75.5% ± 6.6%;P= 0.02).

CONCLUSIONS

When HDMTX (12 g/m2) was used with multiagent therapy for patients with osteosarcoma, very high MTX exposures were associated with poorer outcome. The prospective evaluation of MTX pharmacokinetics and their relation to outcome in a large study is warranted to further substantiate the current findings and to elucidate the causative mechanism.

Design and evaluation of a TOP100 Linux Super Cluster system
Authors: Edmundsson Niklas , Elmroth Erik , Kågström Bo , Mårtensson Markus , Nylén Mats , Sandgren Åke , Wadenstein Mattias
Published: March 2004

The High Performance Computing Center North (HPC2N) Super Cluster is a truly self‐made high‐performance Linux cluster with 240 AMD processors in 120 dual nodes, interconnected with a high‐bandwidth, low‐latency SCI network. This contribution describes the hardware selected for the system, the work needed to build it, important software issues and an extensive performance analysis. The performance is evaluated using a number of state‐of‐the‐art benchmarks and software, including STREAM, Pallas MPI, the Atlas DGEMM, High‐Performance Linpack and NAS Parallel benchmarks. Using these benchmarks we first determine the raw memory bandwidth and network characteristics; the practical peak performance of a single CPU, a single dual‐node and the complete 240‐processor system; and investigate the parallel performance for non‐optimized dusty‐deck Fortran applications. In summary, this $500 000 system is extremely cost‐effective and shows the performance one would expect of a large‐scale supercomputing system with distributed memory architecture. According to the TOP500 list of June 2002, this cluster was the 94th fastest computer in the world. It is now fully operational and stable as the main computing facility at HPC2N. The system's utilization figures exceed 90%, i.e. all 240 processors are on average utilized over 90% of the time, 24 hours a day, seven days a week. Copyright © 2004 John Wiley & Sons, Ltd.
A parallel algorithm for static slicing of concurrent programs
Authors: Goswami D. , Mall R.
Published: March 2004

Slicing of concurrent programs is a compute‐intensive task. To speed up the slicing process, we have developed a parallel algorithm. For this purpose we used the concurrent control flow graph (CCFG) as the intermediate representation. We used a network of communicating processes to develop our parallel algorithm. We have implemented our parallel algorithm and the experimental results appear promising. Copyright © 2004 John Wiley & Sons, Ltd.
