In order to develop an animal model that more closely simulates the organ environment and metastatic routes of human prostatic cancer, R3327-MatLyLu tumors were induced by orthotopic implantation in the ventral prostatic lobe of Copenhagen rats. This procedure reproducibly resulted in metastatic spread of the intraprostatic tumor to the pelvic and retroperitoneal lymph nodes, and invariably to the lungs. Further, a tumor recurrence model was established using an approach that combined orthotopic tumor implantation and subsequent surgical resection of the primary tumor. When prostatectomy was carried out 4 days or more after induction, tumors recurred locally in all animals. The surgical procedures described may provide an animal model to test the in vivo response to experimental adjuvant treatment protocols for advanced prostate cancer. Immunological studies are now in progress using cytokine gene-modified prostatic tumor cells as cellular antitumor vaccines in orthotopically established R3327-MatLyLu tumors.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 July 2010.
All research outputs
#8,234,755
of 24,669,628 outputs
Outputs from The Prostate
#803
of 2,636 outputs
Outputs of similar age
#25,607
of 73,539 outputs
Outputs of similar age from The Prostate
#28
of 128 outputs
Altmetric has tracked 24,669,628 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,636 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 73,539 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 128 others from the same source and published within six weeks on either side of this one. This one is in the 5th percentile – i.e., 5% of its contemporaries scored the same or lower than it.
