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.
Can cancer cause hyponatremia?
However, in most cases, more than one of the aforementioned factors might induce hyponatremia in cancer patients. These causes can be traced back to two different basic mechanisms: excessive free water (for increased intake or reduced elimination) or, rarely, sodium loss (reduced intake or increased loss).
What is the cation of ECF?
Sodium is the major cation of extracellular fluid (ECF ) and the main constituent of serum osmolality. Its concentration in ECF is essential for maintaining the circulating blood volume and it is strictly interdependent of water presence. Normal serum sodium level is 135-145 mmol/L and its imbalance may be caused by alteration of both solute and water intake, depletion, and dilution [ 6].

Furthermore, hyponatremia seems to also have a negative role in hospitalized patients, as it was demonstrated to be associated with a longer length of hospital stay, inducing a negative impact on quality of live and prognosis and an increase in hospitalization costs [ 37].
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.
What is hypernatremia in hospital?
Hypernatremia is defined as an elevated serum sodium level over 145 mmol/L. It is a frequent electrolyte disturbance occurring in 1%-5% of hospitalized patients. It represents a negative prognostic factor, related to an elevated mortality rate (40%-75%) compared to eunatremic patients [ 50].
What is hypercalcemia in a patient?

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 is the association between acute myelogenous leukemia and hypokalemia?
A prominent association between hypokalemia and acute myelogenous leukemia (specifically subtypes M4 and M5) has been noted, with 40% to 60% of these patients developing significant hypokalemia at some point in their disease course.
What is the regulation of phosphate balance?
The regulation of phosphate balance reflects the actions of an array of factors altering phosphate absorption and excretion as well as changes related to the intimate connection between phosphate and calcium levels.
What is TIO syndrome?
More complex, and more rare and indolent, is the syndrome of tumor-induced osteomalacia (TIO), also known as oncogenic osteomalacia, in which tumor production of phosphaturic factors such as FGF-23 results in phosphate wasting, hypophosphatemia, and osteo malacia. Tumor-induced osteomalacia.

What happens if your electrolytes are too high?
For example, if a certain electrolyte is too high, the kidney might try to release more of it in your urine. Problems can happen if electrolytes are too high or too low. That's called an electrolyte imbalance, when the concentration of the specific electrolyte falls outside the normal range. Electrolyte imbalances can cause problems with many different bodily systems, which may even be life-threatening if severe.
