Summary
Cancer cachexia, characterized by anorexia and wasting, affects nearly half of cancer patients. It involves reduced food intake and increased metabolism, necessitating nutritional and metabolic support.
Area of Science:
- Oncology
- Metabolic Medicine
- Nutritional Science
Background:
- Cancer metastases signify advanced, incurable disease.
- Anorexia and wasting (cachexia) are prevalent in terminal cancer.
- Cachexia impacts approximately 50% of cancer diagnoses in Western countries.
Purpose of the Study:
- To elucidate the pathophysiology of cancer-associated cachexia.
- To highlight the dual components of cachexia: reduced food intake and hypermetabolism.
- To underscore the need for integrated patient management.
Main Methods:
- Review of existing literature on cancer cachexia.
- Analysis of the metabolic and physiological changes in cachectic patients.
- Synthesis of pathophysiological mechanisms.
Main Results:
- Cancer cachexia involves both decreased nutritional intake and increased energy expenditure.
- Metabolic alterations accelerate the depletion of protein and energy reserves.
- The syndrome is more severe than predicted by food intake alone.
Conclusions:
- Cancer cachexia is a complex syndrome driven by impaired intake and systemic hypermetabolism.
- Effective management requires nutritional support and metabolic interventions.
- Understanding cachexia is crucial in the context of life-limiting cancer care.

02:53Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:19Psychoneuroimmunology: Diabetes and Cancer
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
