Electrolyte Disorders Associated With Cancer Patients with malignancies commonly experience abnormalities in serum electrolytes, including hyponatremia, hypokalemia, hyperkalemia, hypophosphatemia, and hypercalcemia. In many cases, the causes of these electolyte disturbances are due to common etiologies not unique to the underlying cancer.
What type of cancers cause electrolyte imbalance?
Hypercalcemia and hyponatremia are often observed in patients with breast cancer, renal cancer, prostate cancer, and the like, as a paraneoplastic syndrome. Some part of hypercalcemia results from osteolysis, but the majority is induced by hormonal factors, such as parathyroid hormone-related protein.

Hypercalcemia: A high level of calcium in the blood, called hypercalcemia, may become a medical emergency. This disorder is most commonly caused by cancer or parathyroid disease. Hypercalcemia resulting from cancer is particularly common in conjunction with breast cancer, lung cancer or multiple myeloma and often results from the destruction of bone due to bone metastases.

What are electrolytes? Electrolytes are chemicals in the body that regulate important physiological functions and include sodium, chloride, magnesium, potassium and calcium.
Does chemotherapy affect potassium?
All of these may be side effects of chemotherapy treatment. The kidneys play a critical role in regulating electrolytes. They control the levels of chloride in your blood and “flush out” potassium, magnesium and sodium. Therefore, a disturbance in blood levels of these electrolytes may be related to kidney function.
Can hypercalcemia be diagnosed with cancer?
Coma. These many signs and symptoms are commonly attributed to either the cancer treatment or the cancer itself and may make it difficult for doctors to detect hypercalcemia when it first occurs. This disorder can be severe and difficult to manage.
Why do cancer patients have electrolytes?

What are electrolytes in cancer?
Electrolyte disorders are very common conditions in cancer patients. They mainly concern changes in serum sodium, potassium, calcium, and magnesium levels. In most cases, these alterations are asymptomatic and therefore not always taken into consideration in clinical practice.
What is SIAD in cancer?
SIAD is the principal cause of hyponatremia in oncological and hospitalized patients, occurring in 1%-2% of all subjects and in 30% of cancer patients [ 26]. It is characterized by a deregulated AVP activity, which induces a lower free water excretion.
Which pathway is the most important for sodium balance?
In particular, the angiotensin II arginine vasopressin (AVP) - atrial natriuretic peptide pathway is the most important mechanism of sodium balance [ 7], and it is strictly associated to serum osmolality [ 8].
Where does calcium reabsorption occur in the kidney?
Calcium reabsorption in kidney occurs mainly in the proximal tubules, and a small share in the ascending loop of Henle, thus loop diuretics decrease tubular calcium resorption, whereas thiazide diuretics improve its resorption [ 62]. Calcium metabolism requires a steady interaction between bone and ECF. Several hormones are involved in calcium homeostasis. Parathyroid hormone (PTH), whose secretion is mediated by reduced serum calcium levels, acts on bone, favoring osteoclastic-mediated bone resorption and promoting calcium leakage and it induces the synthesis of active vitamin D and calcium intestinal absorption. Calcitonin instead, whose secretion is mediated by increased serum calcium levels, reduces the transfer of calcium from bone calcium pool to the ECF, and it decreases bone resorption inhibiting osteoclasts’ activity and increases calcium renal excretion [ 63].

Moreover, the development of electrolyte abnormalities is frequently associated with symptoms that negatively affect the quality of life and, in turn, prevent the action of certain chemotherapeutic agents.
Can small molecular targeted drugs cause hypophosphatemia?
Small molecular-targeted medical drugs that are increasingly being used may also exert adverse electrolyte reactions such as hypophosphatemia and hypomagnesemia. Therefore, attentive monitoring of phosphate and magnesium ions in the serum, which is still often neglected, represents a key issue in these cases.
Does carboplatin cause hyponatremia?
A recent study that examined the use of carboplatin in NSCLC found that this condition is significantly associated with the development of hyponatremia. The mechanism responsible for this association could be explained by uncontrolled water ingestion and decreased concentrations of serum electrolytes.

The answer can be found in how electrolyte imbalance and low potassium levels affect cellular processes.
What is the term for the inability of cells to produce energy?
This is called cellular edema, which results in the inability of the normal cells to generate energy (ATP) in a healthy way. They become susceptible to mutation and cancer. Once became cancerous, cells’ normal functions are turned upside down. Instead of generating energy through balanced mineral input and oxygenation, cancer cells generate their version of energy through consuming glucose in an anaerobic environment.
