There are six hallmarks of having full-scale cancer: one hallmark is self-sufficiency in growth signals which is when a proto-oncogene is activated by a mutation to become an oncogene, allowing it to remain on active status inducing cell growth (Gallegos-Arreola et al., 2013). A second hallmark is insensitivity to antigrowth signals; tumor suppressor genes regulate cell proliferation, once knocked out there is no regulation of proliferation, mutations of TP53, a tumor suppressor gene, occurs in only 3% of patients that have ALL (Gallegos-Arreola et al., 2013). A third hallmark is evading apoptosis; types of genes common to be knocked out are from the NOTCH family, since they inhibit apoptosis stimulated by p53 allowing the tumor to worsen,” (Gallegos-Arreola et al., 2013). The fourth hallmark is limitless replication, meaning nothing can stop the growth of the tumor (Huether & McCance, 2012). Fifth hallmark is when the tumor is able to sustain angiogenesis, receiving consistent blood supply and waste removal (Huether & McCance, 2012). Lastly the tumor is able to invade other tissues and metastasized (Huether & McCance, …show more content…
The main points for the pathophysiology of ALL is its ability to reproduce T or B lymphocyte cells with uncontrolled cell proliferation, response to inhibitory signals, and longevity by evading apoptosis. Manifestations for ALL first seem to appear as the flu, however; enlarged lymph nodes, bone and joint pain, and blood tests are more specific to the disease. Treatment for ALL can last up to three years and occur in three phases, induction therapy, consolidation therapy and maintenance
