Abstract:
In patients with lung malignancy, the development of malignant hypercalcemia (MH) carries a dismal prognosis and represents a major therapeutic challenge given that conventional medical treatments have limited durability. Robust and lasting hypercalcemic reversal and symptomatic relief have been documented following surgical tumor resection. Stereotactic body radiation therapy (SBRT) has emerged as an effective treatment modality in medically inoperable patients with Stage I non-small cell lung cancer (NSCLC). In the current report, SBRT achieved durable tumor control and calcemic correction in a medically inoperable 79 year-old man with Stage I NSCLC patient with parathyroid hormone-related peptide (PTHrP)-induced MH.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
