I use to own IRSG, now I own both TITXF and TRXC. I think there is room enough for all 3 devices.

Here in Syracuse, NY it has been the coldest February since they started keeping records in 1902. Average temp has been 10.4 degrees, which is 15 degree below average. We have not broken freezing this month and the highest prediction for the rest of the week is 20 degrees on Saturday. Next coldest month was February 1934 with average temp of 12.5 degrees. Sunday paper showed a picture of Lake Ontario 40 miles North of here with 86 % frozen over. Ontario is a deep lake so it rarely freezes. The east end of Lake Erie is frozen solid. We have double the amount of snow for February, 55 inches, versus average of 25 inches. It has snowed every day this month, which is another record. Since there has been no thaw this month the snow bank are up to my shoulders. I have a plastic push shovel and a Troy Built Plastic Snow Blower with 221 CC engine, It is very light and easy to operate. It works very well because all the power is used to throw the snow. There is no power going to the wheels, but because it is light and the blade pulls it forward it is not needed. I don't believe man has much effect of Global Climate changes, but I wish we could make it warmer. Just a little bit...
Sort of like Musical Chairs with half the chairs missing!
The primary outcome was observation within 1 year after diagnosis. Observation was defined as absence of any accepted treatment for localized prostate cancer, including surgery, radiotherapy, cryoablation, and primary androgen deprivation therapy. The authors defined low-risk disease in accordance with the D'Amico classification system.
The search of the SEER database identified 66,499 men with newly diagnosed localized prostate cancer, of whom 34% met criteria for low risk, 40% intermediate risk, and 26% high risk. Subsequently 12,007 (18%) entered observation within a year of diagnosis.
Use of observation increased modestly but significantly (P
"Our initial results in select patients with renal tumors revealed the short-term safety and efficacy of SRS," the authors concluded. "Single-fraction delivery as an outpatient procedure can avoid treatment-related loss of renal function and hemodialysis. It is a feasible option in patients who are not candidates for alternative treatment modalities.
"To date oncologic results are comparable to those of other ablative techniques for renal tumors and functional results have been excellent. Further studies are needed to determine the limits of SRS in this setting and assess long-term oncologic and functional results."
Observation for Low-Risk Prostate Ca Edges Upward
The proportion of men with low-risk prostate cancer entering observation increased by more than 50% from 2004 to 2009 but remained less than 30%, analysis of a national database showed.
Overall, use of observation increased slightly from 17% to 20% during the 5-year period but jumped from 18% to 29% in the subgroup of men with low-risk disease. The odds for observation doubled for men in the 66-to-69 age group, those with low-risk disease, and patients with no comorbidities, Chad Ritch, MD, MBA, of the University of Miami, and colleagues reported online in the Journal of Urology.
The rationale for the study came from concern about overtreatment of localized prostate cancer, particularly low-risk disease. Moreover, uncertainty exists about the uptake of observation (surveillance) as a disease-management strategy. The authors had a particular interest in temporal trends in the use of observation for men with low-risk disease "who were young and healthy enough to undergo treatment."
Ritch and colleagues retrospectively analyzed of the Medicare-linked Surveillance, Epidemiology, and End Results (SEER) database. They identified all men with newly diagnosed localized prostate cancer from 2004 through 2009.

OncoBriefs: Radiosurgical Success in Renal Cancer
Single-fraction stereotactic radiosurgery (SRS) for unresectable renal tumors led to near-100% local disease control at 9 months in avoidance of nephrectomy, results of a small German study showed.
All but one of 45 treated tumors remained in remission or stable at 9 months following the single treatment session. Lesion shrinkage occurred in 38 of the tumors, including complete remission of 19 tumors, Michael Staehler, MD, of Ludwig Maximilians Universityin Munich, and colleagues reported online in the Journal of Urology.
Single-Fraction Radiosurgery for Renal Tumors
The 45-tumor case-control study involved 40 patients who had impaired renal function associated with an unresectable tumor or for whom nephrectomy was the only treatment option. The study population consisted of 11 patients with transitional cell cancer (TCC) and 29 with renal cell cancer (RCC).
The patients had a median age of 64, median tumor volume of 42 cm2 for TCC and 33.7 cm2 for RCC, and 29 patients had undergone contralateral nephrectomy and had a single remaining kidney.
All surgical procedures were performed with the same type of robotic radiosurgery system. Median follow-up was 28 months and ranged from 6 to 78.3 months.
Treated lesions consisted of 15 TCC tumors and 30 RCC tumors. By RECIST criteria, treatment led to remission in 39 of the 45 lesions, including 19 complete remissions, 13 lesions with more than 30% reduction in diameter, and six lesions with lesser reductions in baseline diameter. None of the TCC lesions was detectable at follow-up.
Kidney function remained stable from baseline (76.8 mL/min/1.73 m2) to last follow-up (70.3 mL/min/1.73 m2). Median progression-free survival and overall survival had yet to be reached.

It sure did especially how he reported we lost the Tet offensive - when we actually decimated the North Vietnamese Army.
Last year's winter was bad. I've lived in Syracuse, NY - 74 years and this winter is one coldest I can remember. I will punch out the next person who says there is anything such a Antropogrnic Global Warming. I hope it is warmer where Cliff has to ship in the Great Lake.
There must be a couple Varian salesmen reading this board :-)
