However, its involvement in cancer and the development of hypercalcemia of malignancy has become a crucial area of research. This article delves into the intricate relationship between PTHrP and cancer, exploring its mechanisms of action, associated symptoms, and diagnostic implications, drawing upon up-to-date scientific understanding.

The Role of PTHrP in Cancer

Parathyroid hormone-related peptide (PTHrP) is structurally similar to parathyroid hormone (PTH) and can exert similar effects on calcium metabolism.作者：M Ito·1997·被引用次数：27—Parathyroid hormone-related peptide (PTHrP)is involved in cell proliferation in both neoplastic and non-neoplastic tissues. We describe an autopsy case of. While normally produced in small amounts by various tissues, its overproduction by malignant cells can lead to significant health complications. Research indicates that PTHrP is occasionally secreted by cancer cells, with a notable association with certain tumor typesHypercalcemia of malignancy caused by parathyroid ....

The most well-established link between PTHrP and cancer is its role in PTHrP-induced hypercalcemia of malignancy. When tumor cells secrete excessive amounts of PTHrP, it mimics the action of parathyroid hormone, leading to an increase in blood calcium levels. This condition, known as humoral hypercalcemia of malignancy (HHM), is a common complication of various cancersHigh levels of PTH-related protein may cause elevated calcium levels in many cancer patients. This condition is referred to as humoral hypercalcemia of .... Studies have shown that PTHrP is the predominant cause of malignancy-associated hypercalcemia, contributing to the majority of cases.

Specific cancers frequently associated with PTHrP secretion include:

* Breast cancer: PTHrP is detected in a significant percentage of primary breast tumors, approximately 60%, and an even higher proportion of bone metastases (over 70%)Parathyroid hormone–related peptide and survival of .... This suggests a strong role for PTHrP in the development and progression of breast cancer, particularly in the context of bone involvement.

* Lung cancer: Especially squamous cell carcinoma of the lung, is strongly linked to PTHrP production.

* Head and neck squamous cell carcinoma: This type of cancer also frequently exhibits PTHrP hypersecretion.作者：N Calvo·2019·被引用次数：31—In this work, we hypothesized thatPTHrPis an important factor that stimulates the interaction between the microenvironment endothelial cells ...

* Kidney cancer (renal cell carcinoma): As noted, PTHrP secretion is occasionally detected in various solid tumors such as renal cell carcinomaA fatal case of parathyroid hormone-related peptide (PTHrP).

* Prostate cancer: Evidence suggests that PTHrP is related to bone metastasis and hypercalcemia in prostate and breast cancers, underscoring its importance in advanced stages of these diseases.

* Islet cell carcinoma: High prevalence of increased parathyroid hormone-related peptide (PTHrP) has been reported in patients with this type of pancreatic cancer, often accompanied by hypercalcemia.作者：A Vakiti·2023·被引用次数：50—The most common cause of malignancy-related hypercalcemia isparathyroid hormone-related peptide(PTHrP). Other common causes include bony metastases and ...

* Other solid tumors: PTHrP production has also been observed in various other solid tumors, highlighting its widespread potential role in oncogenesis.

Mechanisms of Action and Effects

The multifaceted nature of PTHrP extends beyond its calcium-regulating effects.作者：MA Birch·1995·被引用次数：81—Parathyroid hormone (PTH)/PTH-related protein (PTHrP) receptor expression and mitogenic responses in human breastcancercell lines. Research indicates that PTHrP promotes cancer cell proliferation, tumor progression, and metastasis.Pathologic roles of PTHrP.PTHrP is the principal factor in cancer-induced bone diseaseresponsible for humoral hypercalcemia of malignancy and localized ... It can influence the tumor microenvironment and even play a role in tumor-induced cachexia, a wasting syndrome characterized by loss of appetite and muscle mass. PTHrP has been identified as a mediator of adipose tissue browning and tumor-induced cachexia, contributing to increased energy expenditure.

Furthermore, PTHrP 1–34 and PTHrP 140–173 have been shown to protect against apoptosis in lung cancer cells, thus promoting cell survival and tumor growth. It is also involved in cell proliferation in both neoplastic and non-neoplastic tissues, hinting at broader biological functions.2017年11月9日—In 2014 the Spiegelman group suggested thatPTHrP is a mediator of adipose tissue browning and tumor-induced cachexia. PTHrP drives the ...

The elevated levels of PTHrP observed in cancer patients can lead to a condition where high levels of PTH-related protein may cause elevated calcium levels in many cancer patients. This PTHrP-induced hypercalcemia of malignancy is a critical concern that requires careful management.

Diagnosis and Monitoring

The measurement of parathyroid hormone-related peptide (PTHrP) in the blood is a valuable diagnostic tool. A Pth related peptide blood test can help identify elevated levels, which may indicate the presence of a tumor secreting the hormone. This test is particularly useful in the differential diagnosis of hypercalcemia, helping to distinguish between malignancy-related causes and other etiologies. While the precise PTH-related peptide normal range can vary slightly between laboratories, significantly elevated levels are generally indicative of an underlying issue.

The clinical utility of PTHrP extends to prognostic assessment.Bulletin du Cancer - PTHrP and breast cancer - JLE Some studies suggest that patients with cancer and high levels of PTHrP tend to have a worse prognosis compared to those with low levels. However, the prognostic utility of PTHrP is still being explored. Monitoring serum parathyroid hormone–related peptide levels can also be useful in tracking treatment response and disease progression.

Beyond Hypercalcemia

While hypercalcemia is a significant manifestation, the role of PTHrP in cancer is not limited to this alone. It is related to bone metastasis and hypercalcemia in prostate and breast cancers, implying a direct involvement in the spread of cancer to the bones and the associated metabolic disturbances. PTHrP is also recognized as a principal factor in cancer-induced bone disease, contributing to symptoms like bone pain and fracturesAssociation Between Parathyroid Hormone-Related ....

In summary, parathyroid hormone, particularly through its related peptide PTHrP, is intricately linked to the development and progression of various cancers. Understanding the mechanisms by which PTHrP influences tumor growth, metastasis, and metabolic alterations like hypercalcemia is vital for improving patient outcomes作者：CM Edwards·2021·被引用次数：38—Clinical evidence also exists suggesting a role for PTHrP in tumor growth and metastasis in other tumor types.. The PTH-related peptide (PTHrP) serves as both a diagnostic marker and a potential therapeutic target in the ongoing fight against cancer.
