In a recent article published in the Annals of Oncology, Researcher published that Taxotere Cisplatin was a better combination for initial therapy in Metastatic triple negative breast cancer:
"Results:
- The median follow-up was 24 months. ORR was higher in the TP group than in the TX group (63.0% versus 15.4%, P = 0.001).
- PFS
was more than doubled (10.9 months versus 4.8 months, P < 0.001) and
median OS was also greatly improved (32.8 months versus 21.5 months, P =
0.027).
- Toxic effects were not different except G3/4 vomiting and G2/3 hand-foot syndrome.
These results corroborate or tend to support many facts:
1. That triple negative Breast cancer genome was closer to ovarian cancer, a disease in which Taxol -Carboplatin is still standard of care particularly in metastatic setting.
2. That Cisplatin alteration of DNA is more likely to induce P53 cell cycle arrest. (1st law)
3. That adding Taxotere and its disruption of Macrotubules recruits effectively the 2nd law. This lead to a doubling of PROGRESSION FREE SURVIVAL.
Again it would be of interest to see what an Anti-kinesin (anti-Actin) or Velcade addition would mean in a clinical trial. Most molecules involved in programmed cell death such as Cytochrome C are attached to membrane within the organel where they reside. Disrupting that anchor would most likely boost Apoptosis. Without further determining the nature of that Anchor, we know that the cytoskeleton is most likely Actinic in nature. Disruption of the the Cytoskeleton could induced Anoikis, and freedom of molecules attached to membranes leading to major disruption including that of signal pathways.
Velcade main additional effect is disruption of DNA replication restarting after P53 arrest by its affect anti-proteasomic. Protein restarting the replication are generally ubiquitinated making the front and center to proteasome role! The issue really remains the determination of how much of a Driver this pathway is in solid tumor. This determination is one of the major challenge oncologist face today!
