About This Presentation

Description : Check out this medical PowerPoint presentation titled "Advances in Biology and Pathophysiology of Multiple Myeloma” by Amer G. Rassam, MD.

This medical PowerPoint presentation is about multiple myeloma (MM), a type of cancer that affects plasma cells, which are a type of white blood cell that produces antibodies. In MM, abnormal plasma cells, called myeloma cells, grow uncontrollably in the bone marrow and can cause damage to bone and other tissues.

The exact cause of MM is unknown, but it is believed to be a result of genetic mutations in the plasma cells. Risk factors for MM include older age, male gender, exposure to radiation or certain chemicals, and a family history of the disease.

This presentation throws light on the mechanisms involved in the pathophysiology of MM.

History of Multiple Myeloma First case, a London grocer “Thomas Alexander McBean” Jumped from a cave in 1844 According to Drs. Thomas Watson and William MacIntyre, Mr. McBean had “Mollities et Fragilitas Ossium” Mr. McBean died on New Year’s day in 1846

History of Multiple Myeloma Urine sample presented to “Henry Bence Jones” Large amount of protein was found in the sample The protein has became known as Bence Jones Protein

Santiago Ramon Y. Cajal 1852-1934 Paul Gerson Unna 1850-1929 History of Multiple Myeloma In 1890s, Paul Unna and Ramon Cajal identified the plasma cell as a cell type and the cause of Multiple Myeloma
Slide 5-

History of Multiple Myeloma In 1873, Rustizky introduced the name Multiple Myeloma In 1922, Bayne-Jones and Wilson identified 2 distinct groups of Bence Jones protein In 1956, Korngold and Lipari identified the relationship between Bence Jones protein and serum proteins

Dysregulation of cyclin D1, D2, D3 “a unifying oncogenic event in MM” MGUS and MM appear closer to normal PCs than to normal PBs >30% of cells can be in S phase Expression level of cyclin D1, D2, D3 mRNA in MM and MGUS is distinctly higher than normal PCs Expression level of cyclin D2 mRNA is comparable with that expressed in normal proliferating PBs
Slide 21-

Dysregulation of cyclin D1, D2, D3 “a unifying oncogenic event in MM” Cyclin D1 is not expressed in normal hemopoitic cells Cyclin D1 expressed in 40% of MM lacking a t(11;14) translocation Ig translocations that dysregulate cyclin D1 or D3 occur in about 20% of MM tumors Therefore, almost all MM tumors dysregulate at least one of the cyclin D genes

The TC Molecular Classification Predicts Prognosis and Response to Therapies The TC classification may be clinically useful way to classify patients into groups that have distinct subtypes of MM (and MGUS) tumors. The TC classification identifies clinically important molecular subtypes of MM with different prognosis and with unique responses to different treatments.
