The clinical effects of ultrasound-guided microwave ablation in the treatment of primary hepatic carcinoma: Protocol for a retrospective clinical observation.

Instruction: Despite the continuous advancement of liver cancer diagnosis technology and level, there are still nearly two-thirds of patients with primary liver cancer that are already advanced at the time of diagnosis. Ultrasound-guided microwave ablation, as a palliative treatment for intermediate and advanced liver cancer, is currently recognized internationally Standard treatment for patients with unresectable hepatocellular carcinoma. However, recently, some scholars hold that ultrasound-guided microwave ablation does not guarantee complete inactivation of tumor lesions.

[A case-control study on serum organochlorines residues, genetic polymorphisms of glutathione S-transferase T1 and the risks of breast cancer].

Objective: To study the potential effect of gene-environment interaction between glutathione S-transferase T1 (GSTT1) and serum organochlorines residues on the risk of breast cancer in women, in China.

Methods: 70 newly diagnosed female breast cancer patients and 30 controls from September 2006 to October 2007 were interviewed using the same questionnaire to obtain information regarding exposure to those risks. Organochlorine residues level in serum was measured by gas chromatography (GC).
