Advanced non-small-cell lung cancers are diseases of late diagnosis with bad prognosis. Conventional chemotherapies are not very efficient. Over the last years, many research works have been performed in this way to improve prognosis. Targeted therapies seem promising. They were notably developed against epithelial growth factor receptors and tumoral angiogenesis. We report here the clinical history of a patient with an advanced non-small-cell lung cancer presenting an exceptional response to small-molecule tyrosine kinase inhibitors. [less ▲]

Objective: Genetic disorders of calcium metabolism arise in a familial or sporadic setting. The calcium-sensing receptor (CaSR) plays a key role in maintaining calcium homeostasis and study of the CASR gene can be clinically useful in determining etiology and appropriate therapeutic approaches. We report two cases of novel CASR gene mutations that illustrate the varying clinical presentations and discuss these in terms of the current understanding of CaSR function. Patients and Methods: A 16 yr-old patient had mild hypercalcemia associated with low-normal urinary calcium excretion and normal-to-high parathyroid hormone (PTH) levels. Because of negative family history, familial hypocalciuric hypercalcemia (FHH) was originally excluded. The second patient was a 54 yr-old man with symptomatic hypocalcemia, hyperphosphatemia, low PTH, and mild hypercalciuria. Familial investigation revealed the same phenotype in the patient's sister. The coding region of the CaSR gene was sequenced in both probands and their available first-degree relatives. Results: The first patient had a novel heterozygous inactivating CASR mutation in exon 4, which predicted a p.A423K change; genetic analysis was negative in the parents. The second patient had a novel heterozygous activating CASR mutation in exon 6, which predicted a p.E556K change; the affected sister of the proband was also positive. Conclusions: We reported two novel heterozygous mutations of the CASR gene, an inactivating mutation in exon 4 and the first activating mutation reported to date in exon 6. These cases illustrate the importance of genetic testing of CASR gene to aid correct diagnosis and to assist in clinical management. [less ▲]
