1.Diagnosis, treatment and prognosis of uterine cervical neoplasms complicated with pregnancy
Journal of International Oncology 2013;(2):145-148
The incidence of cervical neoplasms complicated with pregnancy is rising,with delaying of reproouctive age.Because of the prevalence of cytology in pregnancy.eervical neoplasnis complicated with pregnancy are mostly detected early. All patients with cytological abnormalities should undergo colposcopy, and when necessary,they should undergo cervical biopsy.Conization is reserved for patients with suspected invasion.In cases of invasive carcinoma detected up to the 12th week of pregnancy,immediate treatment is prioritized.Regarding diagnoses made during the second trimester,in early-stage invasive cancers,delay of therapy seems to be safe.fetal pulmonary maturity can be awaited.And the use of neoadjuvant chemotherapy to stabilize the disease until the time of delivery appears to be viable.Doctors should draw up personalized program for the patients with cervical neoplasms complicated with pregnancy according to stage of disease, gestational weeks and the patient's desire for continued pregnancy.Cervical neoplasms complicated with pregnancy are mostly early-stageinvasive cancers, so prognosis is good.
2.Epithelial-mesenchymal transition and cancer stem cells
Journal of International Oncology 2013;(3):177-180
Epithelial-mesenchymal transition (EMT) not only can endow cells migration and invasion characteristics,but also can make tumor cells obtain self-renewal ability and have the characteristics of stem cells,which might result in cancer stem cell (CSCs).There are the same molecular mechanism and microenvironment between EMT and CSCs,which have great clinic significances for the diagnosis and treatment of the aggressive cancers.Moreover,many studies show that miR-200 could regulate EMT and CSC,participate in the tumor invasion and metastasi,and promote the research of targeted cancer therapy.
