Study Notes

Overview of Neoplasia and Cancer, Cell Cycle, Checkpoints, and Treatment

Neoplasia is the uncontrolled growth of new tissue that forms a tumor, which can be malignant or benign.
Cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells that can lead to death if left untreated.
Malignant tumors can invade surrounding tissues and spread to distant locations in the body, while benign tumors do not possess this capability.
Cancer is generally associated with genetic defects that can cause abnormalities in cell cycle regulation, evasion of apoptosis, limitless cell division, angiogenesis, tissue invasion, and metastasis.
The cell cycle is a four-stage process consisting of G1 phase, S phase, G2 phase, and M phase, which results in the replication of all genetic material and division into two identical cells.
Within the cell cycle, there are various surveillance mechanisms known as checkpoints that assess the integrity of the process and can be defective in tumor cells.
Traditional approaches to the treatment of cancer include surgery, radiotherapy, and chemotherapy.
Chemotherapy refers to drugs that are used to kill cells and includes antibiotics and agents used in the treatment of cancer.
Most traditional anticancer drugs work by disrupting the function of DNA directly or indirectly, and a combination therapy of various anticancer drugs is more effective than using a single drug.
Antineoplastic agents can be classified into alkylating agents, antimetabolites, antibiotics and natural products, hormone-based therapies, inhibitors of signaling pathways, and miscellaneous enzyme inhibitors.
Alkylating agents are a class of drugs that form covalent bonds with important biomolecules, primarily nucleophilic groups present on DNA, proteins, and other biomolecules.
Molecular targeted therapeutics are highly selective agents that target specific molecular targets that are abnormal or overexpressed in the cancer cell and are entering a new era of cancer chemotherapy.
