Serum and Saliva Levels of Cancer Antigen 15-3, Carcinoembryonic Antigen, Estradiol, Vaspin, and Obestatin as Biomarkers for the Diagnosis of Breast Cancer in Postmenopausal Women.

Objective: To find suitable biomarkers for diagnosis of Breast cancer in serum and saliva; also, to examine the correlation between salivary and serum concentrations of suitable biomarkers.

Methods: This case-control study included 30 women with breast cancer as a case group and 30 healthy women as a matched control group. Blood and saliva specimens were collected from all participants.

Comparison of sublingual buprenorphine and intravenous morphine in reducing bone metastases associated pain in cancer patients.

Bone metastases is one of the most common causes of pain in cancer patients and have a significant effect on their quality of life. The most common symptom of bone metastases is pain that gradually develops. Morphine is used to relieve pain in these patients, but poorly accepted due to its adverse events.

Dose-response relationship and normal-tissue complication probability of conductive hearing loss in patients undergoing head-and-neck or cranial radiotherapy: A prospective study including 70 ears.

Purpose: Head-and-neck (H&N) and cranial radiotherapy may cause hearing loss. Little has been published on the dose-response relationship and normal-tissue complication probability (NTCP) of the conductive subtype of hearing loss. The aims were to observe the incidence of hearing loss in patients undergoing non-intensity-modulated H&N or cranial radiotherapy, obtain the relationship between dose and conductive hearing loss (CHL) and test the current Lyman-Kutcher-Burman (LKB) NTCP model parameters.
