This is the website where my dad Gil Segal and his violin partner John Dolan put songs they both played on the net.
This is a CD that John's grown kids had him make for them, both mom and I wanted my dad to make one of just his songs but unfortunately his cancer took over and he died before he could make one.
My dad's signature song: Meditation from the opera Thais is on this website. It was dad's favorite as well as my mom and mine.
I hope these songs come to bring you comfort and peace just like they have for all of us.
This is a place to be able to share thoughts, fears, and tears surrounded by a cancer diagnosis. Whether you are a cancer survivor, still going through treatment, or are a caregiver, this forum is for you.
a must read for cancer survivors....
There is a new TV show called Your Cancer Today. They talk about reaserch and they have survivors tell their story. I found this program by accident on a public interest channel. The Web Site have archived programs.

Functional profiling with cell culture assays for targeted drug therapy
Recent findings presented at the American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium in Orlando, Florida concluded that Functional Profiling (whole cell profiling) with cell culture assays is relevant for the study of both "conventional" and "targeted" antineoplastic drug agents.
Cell Culture Assays with "cell-death" endpoints can show disease-specific drug activity, are useful clinical and research tools for "conventional" and "targeted" drugs, and provide unique information complementary to that provided by "molecular" tests. There have been more than 25 peer-reviewed publicatons showing significant correlations between cell-death assay results and patient response and survival.
The Whole Cell Profiling technique is a cell-death endpoint assay in which drug effect upon cancer cells is visualized directly. Photomicrographs of actual tumor cells sometime show that the exact same identical individual culture well, shows some clusters have taken up vast amounts of a drug, while right next door, clusters of the same size, same appearance, same everything haven't taken up any of the drug.
So it doesn't matter if there is a "target" molecule (protein or receptor) in the cell that the targeted drug is going after, if the drug either won't "get in" in the first place or if it gets pumped out/extruded or if it gets immediately metabolized inside the cell, drug resistance is multifactorial. The advantage of the Whole Cell Profiling technique is that it can show this in the "population" of cells.
The Whole Cell Profiling technique makes the statistically significant association between prospectively reported test results and patient survival. It can correlate test results which are obtained in the lab and reported to physicians prior to patient treatment, with significantly longer or shorter overall patient survival depending upon whether the drug was found to be effective or ineffective at killing the patient's tumor cells in the laboratory.
This could help solve the problem of knowing which patients can tolerate costly, new treatments and their harmful side-effects. These "smart" drugs are a really exciting element of cancer medicine, but do not work for everyone, and a test to determine the efficacy of these drugs in a patient could be the first crucial step in personalizing treatment to the individual.

Abstract: Introduction: We studied the relevance of FP for standard and targeted drugs.
Methods: Drugs were tested against fresh human tumor microclusters, with 96 hr drug exposures and multiple FP endpoints (MTT, DISC, resazurin, and/or ATP).
Results: In 65 previously chemonaive stage 4 colon cancer patients, those with FP assays showing 5FU results in the most resistant tertile had inferior overall survival, compared to pts without 5FU resistance (303 days vs. 686 days, H.R. 2.1, 95% C.I. 1.2 - 5.0, P2=0.011). In subset analysis restricted only to 53 pts who subsequently died (eliminating potential surgical cures), the respective results were 292 vs 493 days, HR 1.5 - 6.9, P2=0.0021. We applied FP to test targeted agents, including gefitinib, erlotinib, sunitinib, sorafenib, and bevacizumab. Gefitinib was tested against > 700 fresh tumor specimens; we reported striking correlations between gefitinib activity and overall pt survival in non-small lung cancer (2006 ASCO Annu Mtg, Abst 17117). Gefitinib and erlotinib are moderately cross resistant (R2=0.48, n paired comparisons=190). Gefitinib/sunitinib (R2=0.20, n=46) and erlotinib/sunitinib (R2=0.12, n=44) are largely non-cross resistant. We also developed a new microvascular viability assay (MVVA) to test microvascular cells present in tumor clusters. In the MVVA, bevacizumab was tested in 81 fresh tumor specimens (including 15 GI). Bevacizumab was nontoxic to the tumor cells, but often strikingly toxic to microvascular cells present within the same tumor clusters. Grading on a 0-4 scale, there was absent (Gr 0) effect in 23 specimens, weak (Gr 1-2) effect in 28, and a strong (Gr 3-4) effect in 26. In contrast to bevacizumab, neither sunitinib (n=87) nor sorafenib (n=20) showed selective effects against microvascular cells compared to tumor cells.
Conclusions: We cannot rule out a cytostatic effect of sunitinib or sorafenib on tumor microvascular cells. However, our results imply that the antitumor effects of bevacizumab are predominately mediated through antimicrovascular effects, while effects of sunitinib and sorafenib may be mediated largely through tumor cell apoptosis. We conclude that FP is relevant for the study of both traditional and targeted antineoplastic agents.
