1.Research advances in radiotherapy after mastectomy combined with phase I breast reconstruction for invasive breast cancer
Chinese Journal of Radiation Oncology 2016;25(10):1125-1129
The increasing need for ideal body shape makes more and more patients choose to receive different types of breast reconstruction surgery after mastectomy. Right now, it is a key problem for the multidisciplinary treatment to find an optimal sequence of comprehensive treatment from which those patients can receive the maximum benefits and a good balance between ideal body shape and satisfactory antitumor outcomes. This paper reviews the latest research advances in the effect of postoperative radiotherapy on breast shape after breast reconstruction, the sequential relationship between the replacement of the temporary tissue expander with the permanent breast prosthesis and postoperative radiotherapy, breast construction surgery, and radiotherapy techniques. To provide a basis for clinical practice, this paper proposes a flow chart for decision?making in reconstruction surgery and adjuvant treatment based on the current literature and clinical data.

3.Surgical management and prognostic analysis on recurrent colorectal carcinomas
China Oncology 1998;0(01):-
Background and purpose:Colorectal cancer is one of the most common malignant tumors.Radical operation remains the primary treatment for the disease.Postoperative recurrence and metastases are the main cause for the patient' death.Reoperation for recurrent colorectal cancer is one of the methods to improve survival rate and quality of life for those patients.This study aimed to explore the cause,diagnosis and surgical treatment of recurrent colorectal cancer after operation.Methods:Thirty-five cases of postoperatively recurrent colorectal carcinoma who were treated from 2003 to 2006 at the Department of Surgical Oncology,2th Hospital of Jiaxing were retrospectively analyzed.Results:35 cases of colorectal cancers were re-operated and the overall rate of resection was 63 %,12 of them received radical resection with 4 recurrent rectal cancers and 8 recurrent colon cancers while others were palliatively treated.We followed up these patients from 6 to 36 months and there were 9 cases in 12 cases of radical respected group who were disease free,1 of them had lung metastases,1 liver metastases.While 23 cases in the palliative group,5 were dead,4 had liver metastases and 12 cases were alive.Of the 35 cases,26 cases(70%)tumor recurred within 3 years after first operations while others were recurrent at 1 year.Conclusions:For the patients with recurrent colorectal cancer,surgery remains one of the choices for the treatment.Multimodality treatment should be recommended for the patients at diagnosis.Completed resection of intestine with primary lesion,standard lymphadenectomy and eradicating peritoneal exfoliated cancer cells are the major steps to prevent recurrence of colorectal cancer.
4.Cochlear implant operation to summarize and postoperative outcome.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(22):1768-1773
OBJECTIVE:
The aim of this study was to evaluate the clinical features of cochlear reimplantation. To review our experience of cochlear reimplant surgery.
METHOD:
Retrospective analysis of all 25 cochlear reimplant surgeries between 2002 and 2012. Causes of revision operations, number of electrode channels inserted, surgical findings and postoperative speech performances were analyzed.
RESULT:
Causes of reimplantation were eight hard failures; eight poor implanted electrodes position, four poor outcome, three skin flap infection lead to implant device exposure, one postoperative symptoms of facial nerve stimulation, one postoperative temporal bone lesions. All cochlear reimplantations were successfully performed in our hospital, audiologic performances were stable or improved following reimplantation in most of cases.
CONCLUSION
Cochlear implant surgeons should have a good knowledge of how to diagnose cochlear implant failures and how to deal with medical complications related to cochlear implantation. Medical and audiologic outcomes are generally excellent. Cochlear reimplantation appears to be a safe and effective.

5.Cochlear implantation in patients with cochlear ossification.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(10):688-692
OBJECTIVE:
To investigate cochlear implantation surgical techniques and postoperative results in patients with cochlear ossification.
METHOD:
Twenty-nine cochlear ossification patients with cochlear implantation in our department were retrospectively studied during 1997-2011. Preoperative imaging and electrophysiological assessment were done to classify the cochlear ossification of all the patients. Categories of auditory performance and speech intelligibility rating were detected to assess the outcome of cochlear implant postoperatively.
RESULT:
Among 29 cases with cochlear ossification, 19 cases were grade II, 4 cases were grade I, 4 cases were grade III, and 2 cases were apical turn ossification. Among 23 patients with cochlear ossification grade I and II, 17 cases were totally cochlear array insertion, and 6 cases were partial cochlear array insertion. Patients with cochlear ossification grade III were all partial cochlear array insertion. Most patients achieved good hearing and language ability after cochlear implantation.
CONCLUSION
Cochlear implantation can be successfully performed on the basis of systematic preoperative assessment and some patients can achieve good postoperative results in patients with cochlear ossification. Intraoperative electrical stimulation of the auditory evoked response provides a good method to assess the residual spiral nerve function.

8. Isolation and detection of circulating tumor cells: Recent progress
Academic Journal of Second Military Medical University 2010;31(3):313-316
Disseminated malignancy is the main cause of cancer-related death. The spontaneous circulation of tumor cells is responsible for distant metastasis; therefore it is of potential importance to specifically and sensitively detect the circulating tumor cells, which not only allows for more accurate prediction of cancer prognosis, but also helps to tailor individualized anticancer treatment. This paper reviews the enrichment, detection and analyzing methods of circulating tumor cells.

Objective To determine the three-dimensional (3D) texture features extracted from intensity and high-order derivative maps that could reflect textural differences between bladder tumors and wall tissues,in order to achieve bladder cancer and wall tissue identification.Methods A total of 62 cancerous and 62 wall volumes of interest (VOI) were extracted from T2-weighted MRI datasets of 62 patients with pathologically confirmed bladder cancer.To reflect heterogeneous distribution of tumor tissues,3D high-order derivative maps (the gradient and curvature maps) were calculated from each VOI.Then 3D Haralick features based on intensity and high-order derivative maps and Tamura features based on intensity maps were extracted from each VOI.Statistical analysis was proposed to first select the features with significant differences and then obtain a more predictive and compact feature subset to verify its differentiation performance.Results From each VOI,a total of 58 texture features were derived.Among them,37 features showed significant inter-class differences (P≤ 0.01).Conclusion The results suggest that 3D texture features deriving from intensity and high-order derivative maps can reflect heterogeneous distribution of cancerous tissues.
