Hypofractioned radiosurgical treatment of prostate cancer have been theorized to improve the tumor control over the conventional radiotherapy due to low alpha/beta ratio of prostate. Infact, the low α/ß ratio for prostate cancer require high radiation dose for the tumor control and an hypofractionated schedule with a dose of 38 Gy in four fractions as calculated biologically lethal for the prostate cells cancer. In this report we summarized a preliminary experience with planning target about the volume coverage, rectum, urethra and bladder exposure.
PATIENTS AND METHODS:
The Virtual HDR Cyberknife is indicated for patients with localized cancer prostate (T1-T2b) with favorable prognosis (Gleason score ≤ 6, PSA ≤ 10 ng/ml) and select patients with intermediate prognosis (Gleason score of 7, PSA 10,2-20 ng/ml). The PTV, defined with MRI and CT imaging, included the prostate and seminal vesicle, plus 2 mm of expansion for favorable prognosis or 5 mm for intermediate prognosis in all direction except posteriorly. Prior to treatment planning, one week before, 4 gold fiducials are placed into the prostate with ultrasound guidance.
For our patients treated with Cyberknife the prescription dose is 38 Gy in four fractions at the median prescription isodose line is 65%. The median PTV was: V100 97%, V125 38%, V150 0,61% and D90 4092 cGy. The median exposure urethra was: DMax 4300 cGy, D10 4150 cGy and D50 3683 cGy. The median bladder dose was DMax 3600 cGy and D10 2600 cGy. The median rectal wall dose was DMax 3300 cGy, D1 3273 cGy, D10 2163 cGy, D25 1578 cGy and V80 1,3 ml. the median rectal mucosa dose was DMax 3000 cGy, D1 2806 cGy, D10 2040 cGy, D25 1600 cGy and V80 0,06 ml. PSA levels have steadily decreased to be normal following post-therapy for all patients.
The Cyberknife is a imaging guided device for delivering high radiation doses to a precisely three dimensional target volume. It is a non invasive method with excellent short-term PSA response and very low levels of complications. This preliminary report need of further confirms for late complication and effective tumor control.

*Department of Radiological Science, Operative Unit of Radiotherapy University of Messina.
To determine the efficacy of Cyberknife, new frameless imagine-guided, for primary and recurrent head and neck carcinomas.
MATERIALS AND METHODS:
Between July 2007 and April 2009, 12 patients with a median age of 59 years (range 25-72 ) were treated by Cyberknife stereotactic radiosurgery for head and neck cancers. There were 7 female ( 58,4 %) and 5 male (41,6%). The principal primitive tumors responsible of the lesions have been: nasopharyngeal cancer ( 4 cases), lacrimal gland cancer(2), minor salivary gland cancer(1), plasmocitoma(3), tonsil cancer (1), LNH ( 1) . In our centre, we have treated six ( 6 ) primary sites of desease ( orbit, skull-base, maxillary sinus and clivus) and six ( 6 ) locally recurrent HNC (sphenoid sinus, nasopharyngeal and lymphnodes). Three patients were reirradiated and one received concomitant cetuximab (400 mg/mq the week before the start of radiotherapy and 250mg/mq weekly during four weeks). Median dose prescribed was 20,5 Gy( range15-36 Gy); the median prescription isodose was typically 75%( range 60-83 % ) ; the treatment was fractionated for ten patients and in single fraction for two patients. The median target volume was 12,47 cc (range 1,3 -55,5 cc). Non-isocentric conformal treatment plan were used for all patients. Tracking with Xsight Spine or 6D skull was systematically used. Median follow-up was 21months.
At three months, six patients had complete regression of the lesions after CKSRS, five had partial response, and one had progression of disease. The overall response rate was 99 %. CK-SRS and FSRT established ultimate disease control in 99 % of the patients.
Our early results is encouraging that CK SRS and FSRT are an effective
treatment modality with acceptable morbidity for salvage treatment of HCN. Hypofractionated stereotactic radiotherapy is a new potentially curative therapeutic option for reirradiation of head and neck carcinomas. The Cyberknife offers an alternative therapeutic modality for treatment of skull-base tumors in case in which surgery cannot be performed or located in critical area.
However, more experience and longer follow-up with increased number of patients would be necessary to determined the role of fractionated stereotactic radiosurgery in this group of patients.

>>With more than 20 new models due this year, South Korea's Samsung Electronics rushes to catch up in the fast-growing smartphone market
More Than 20 Smartphone Models Due
Samsung's approach is starkly different from Apple's. While the real beauty of the iPhone and its latest successor, the iPhone 3G S, lies in the creative use of the iTunes Store to inspire a myriad of third-party developers to write applications for the phones, Samsung's emphasis is more on hardware. To expand its presence, Samsung plans to keep rolling out new lineups of smartphones—more than 20 different models this year alone—to cater to different consumer segments.
Samsung isn't following Apple's initiative to set business direction in partnership with mobile carriers, either. Instead, Samsung lets service providers call the shots as a way to increase its handset market share. "We will continue strengthening our relationship with key operators and work closely with them to develop smartphones meeting their specific needs and to help their business," says Hong.
Such tactics have started to pay off in the U.S., where Samsung has steadily increased its presence. In the first three months of this year, Samsung was the No. 1 handset brand in North America with a market share of 26.3%, vs. Motorola's 18% and Nokia's 7.9%, according to Strategy Analytics data.

>>Trans-Atlantic bandwidth – the hangover lingers
Despite the balancing of supply, demand, and price since the turmoil of the early 2000s, the market for trans-Atlantic bandwidth faces a looming supply hurdle. The trans-Atlantic submarine cable market was a stark example of the capacity glut in the early 2000s. Six new cables entered service between 2000 and 2003, greatly exceeding near-term requirements. The excess capacity and competition crushed prices, resulting in a wave of bankruptcies and financial restructuring.
The bandwidth glut now lies well in the past: rapidly growing international bandwidth requirements restored the balance of supply and demand, and cable operators have been adding capacity to their networks since 2004. Superficially, the trans-Atlantic market now appears sound: prices have stabilized, and demand grew 38% in 2008. However, clouds loom on the horizon.
>>Type of prostate cancer therapy (CK) targeted for Medicare cut
Decision is pending whether the program will cover CyberKnife
Monday, Jun 22, 2009
Despite passionate support for the device from patients and physicians, that’s a very real possibility. The contractor that decides what Medicare will cover in Florida is considering stopping coverage of prostate cancer therapies that use the CyberKnife and similar devices.
The contractor, Jacksonville-based First Coast Service Options, said in a coverage report that “literature does not support an outcome advantage [with the CyberKnife] over other conventional radiation modalities.” That decision is largely based on a 2008 report by an influential radiation oncology group that reviewed several studies and reached a similar conclusion about the therapy.
“However,” the American Society for Radiation Oncology report added, “the overall potential benefits in terms of clinical outcomes, cost-effectiveness and patient convenience are promising aspects of this paradigm shift that warrant further investment and investigation.”
Pulling Medicare coverage for prostate therapy likely would trigger a domino effect of private insurance carriers also pulling their coverage of the procedure, experts say. Since prostate cancer is so common — afflicting 125 of 100,000 men in Florida, many of them old enough to have Medicare coverage — the determination stands to strike a severe blow to the state’s CyberKnife centers.

Morgan Joseph initiates coverage on Equinix (
Morgan analyst says, "We believe it has entered into a promising revenue cycle with new centers now online, and additional expansion anticipated coming online over the next year, with a 15% increase in capacity expected by 1Q10. Our price target of $100.00 is based on an approximate 10x 2010E EV/EBITDA multiple. We estimate 2010 sales and adjusted EBITDA of $1.03bn and $480mm, respectively, vs. our 2009 estimates of $864mm and $385mm. As demand for Internet infrastructure increases, and Equinix's ability to fully fund its growth to meet demand going forward, we believe our estimates are reasonable...We believe the growing demand for bandwidth has driven, and is expected to continue driving, colocation and interconnection services."
