Objective To summarize the description about the pure noninvasive breast carcinoman in guidelines. Methods The related guidelines and literatures about the pure noninvasive breast carcinoma were collected to make a review. Results Through reviewing the guidelines of breast carcinoma, including Chinese Anti Cancer Association (CACA), National Comprehensive Cancer Network (NCCN), St.Gallen, European Society for Medical Oncology Clinical Practice Guidelines for Diagnosis, Treatment and Follow-up, as well as Japanese Breast Cancer Society Clinical Practice Guideline, we find that, the main treatment of noninvasive breast carcinoma is operation and the surgery for axillary is not recommended by most guidelines. The sentinel lymph node biopsy (SLNB) should be performed only when the invasive ductal carcinoma (IDC) is suspected or location of lesion would decrease the success of SLNB in the future. The radiotherapy should be advised to patients following conservation surgery. The patients with estrogen receptor (ER)-positive should undergo endocrine therapy. However, the using of endocrine therapy should be discussed with patient. Conclusions Although the prognosis of pure noninvasive breast carcinoma is better than invasive cancer, the research about it is still less, and the treatments recommended by guidelines are different. The more attention should be paid to the research about the pure noninvasive carcinoma.
Objective To evaluate the relevant systematic reviews/meta-analyses that focused on the prevention and treatment of complications after impacted tooth extraction. Methods The systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction were searched in PubMed, The Cochrane Library, CBM, CNKI and WanFang Data from inception to September 30th, 2012, and a total of 15 professional journals and the references of included studies were also retrieved manually. Two reviewers screened the literature according to the inclusion criteria and extracted the data. Then the AMSTAR was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence. Results A total of twelve relevant systematic reviews/meta-analyses were included, of which five focused on the prevention and treatment of dry socket, six on the prevention of swelling, seven on the prevention and treatment of pain, six on the prevention of limitation of mouth opening, two on the prevention of infection, three on the prevention of bleeding, and one on the treatment of nerve damage after tooth extraction. Based on AMSTAR, seven studies were minor limitations and five studies were moderate limitations. Based on GRADE system, two was high quality of evidence, twelve were moderate, nine were low, and seven were very low. Conclusion Currently, the systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction can provide some references for clinical practice, which should be combined with the real condition by clinical doctors when making an evidence-based decision. However, it also suggests performing more high quality and large sample studies to prove this conclusion.
Objective To summarize the research progress of distributional heterogeneity of the molecular pathology characteristics in breast cancer. Methods The related literatures about the distribution of the molecular pathology characteristics in breast cancer were reviewed. Results The breast cancer had the same heterogeneity as other cancers. At the same time, the molecular pathology characteristics, such as estrogen receptor (ER), progesterone receptor (PR), Ki-67, and human epidermal growth factor receptor-2 (HER-2), had the distributional heterogeneity. The distributional heterogeneity of molecular pathology characteristics in breast cancer could effect the pathologic diagnosis, the treatment, and the prognosis. Conclusion Although there are some new techniques which were used to investigate the heterogeneity of breast cancer, but each way has some problems. The more attention should be paid to the research about the distributional heterogeneity of the molecular pathology characteristics in breast cancer.
CT texture analysis (CTTA) can objectively evaluate the heterogeneity of tissues and their lesions beyond the ability of subjective visual interpretation by extracting the texture features of CT images, then performing analysis and quantitative and objective evaluation, reflecting the tissue micro environmental information. This article reviews the recent studies on the applications of CTTA in gastric cancers, in the aspects of identification of gastric tumors, prediction of stage, correlation with Lauren classification, prediction of occult peritoneal carcinomatosis, evaluation of efficacy and prognosis, and prediction of biomarkers. It is regarded that CTTA has a good application prospect in gastric cancers.
