Intravenous gamma globulin (IVIg) is produced from a pool of precipitated IgG from over 3,000 healthy donors. IVIg was originally given to subjects with Igs deficiencies. Later on its beneficial effects on a diverse autoimmune clinical conditions were revealed. Based on large experimental studies in mice as well as limited clinical experience, we consider IVIg useful in preventing metastatic spread. In mice, the employment of IVIg reduced significantly metastatic spread of melanoma, carcinoma and sarcoma. The effect of IVIg was achieved following i.v. or s.c. administration at high dose (2 g/kg body weight) and at 100 times lower doses. The effect of IVIg on the prevention of metastases are diverse and achieved via enhancement of IL-12 secretion and increased NK activity as well as inhibition of matrix metalloproteinase-9 (MMP-9). The lack of serious side effects with the remarkable decrease in metastatic spread make IVIg a suitable adjuvant therapy in early and advanced cancer conditions.

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Treatment Resistent Cancers02:56

Treatment Resistent Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
