1.Magnetic resonance imaging diagnosis of hilar cholangiocarcinoma
Chinese Journal of Digestive Surgery 2013;(3):196-199
Hilar cholangiocarcinoma (HCCA) or Klatskin tumor is a scirrhous adenocarcinoma that arises from the conjunction of bile duct and hepatic ducts.Hepatic magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) are important methods for the diagnosis of HCCA.In this article,the clinical data of 42 patients in the Changhai Hospital and 18 patients in the Eastern Hepatobiliary Surgery Hospital who received MRI and MRCP examination from October 2010 to October 2012 were retrospectively analyzed.According to the pathological features,HCCA could be divided into mass-forming type,infiltrating type and intraductal type.Based on the results of imaging examination and intra-and postoperative pathological examination,Bismuth-Corlette types were decided pre-and postoperatively.The coincidence rate of pre-and postoperative Bismuth-Corlette types was 89.7% (35/39).Infiltration of liver parenchyma was both detected pre-and postoperatively in 19 patients (16 patients were detected by MRI preoperatively),and the sensitivity of MRI was 84.2% ; vascular invasion was both detected pre-and postoperatively in 10 patients (12 patients were detected by MRI preoperatively),and the sensitivity of MRI was 83.3% ; hilar and retroperitoneal lymph node metastasis was both detected pre-and postoperatively in 6 patients (4 patients were detected by MRI preoperatively),and the sensitivity of MRI was 66.7%.Combined application of different sequences and techniques of MRI is helpful in the diagnosis,staging and treatment of HCCA.

China Oncology 2013;(8):590-595
Breast cancer is the most common disease in women worldwide, which not only threatened the women’s survival time, but also inlfuenced their quality of life as well. Within this challenge, it’s important to optimize the current multidisciplinary treatment stratagem for breast cancer. Radiotherapy is one of the most important treatment modality for patients with breast cancer, with the trend to shrink the irradiated volume and shorten the total fraction times in recent years. Intraoperative radiation therapy (IORT) as a fast and convenient procedure has the ability to deliver a high, single-fraction radiation dose to tumor beds with minimal exposure of surrounding tissues (lung, heart, etc.), which could be displaced or shielded right after the tumor removal during the surgical procedure. Right now, IORT has been either integrated as a boost technique in multimodal approaches using postoperative EBRT in the treatment of early breast cancer patients undergoing breast conservation surgery or used as a single dose accelerated partial breast irradiation technique for these patients. This review discussed the rationale of IORT, the beneifts and limitations of IORT, the indication and the clinical results of this procedure, including treatment related side-effects as well in order to provide the preliminary evidence based approach for early breast cancer patients.

Radiotherapy is one of the main means of local treatment of breast cancer. Triple negative breast cancer (TNBC) as a molecular subtypes of breast cancer, its biological behavior is special and existing multiple molecular targets, these molecular targets inlfuence the response of ionization radiation through different mechanisms and regulate radiotherapy sensitivity of TNBC This article reviewed the recent advances in radiotherapy and radiosensitivity related molecular targets of TNBC.
4.Recent advances in breast cancer stem cell phenotypes and clinical application
China Oncology 2016;26(8):699-703
The cancer stem cell theory suggests that cancer develops from a subset of tumor cells that possess characteristics of stem cells. Breast cancer stem cells comprise a sub-population, which possesses the capacity of self-renewal and the potential for differentiation and high tumorigenicity. Evidence from bothin vitro andin vivo studies demonstrates breast cancer stem cells are responsible for tumor relapse, invasion and metastasis, chemo- and radio-resistance and epithelial-mesenchymal transition (EMT). Herein, this review highlighted the recent advances in breast cancer stem cells.
5.The strategies for the treatment of prostate cancer with bone metastases
China Oncology 2001;0(03):-
Bone is the most common site for metastasis from prostate cancer, and bone metastases also is one of the main causes for the death of the patients with prostate cancer. Since the patients with bone metastases from prostate cancer still have relatively long survival periods after treatmemt, how to properly choose the treatment option for the metastatic patients is imperative in terms of improvements in both quality of life and life expectation. This paper summary pathophysiology, risk evaluation clinical assessment and the current status of the treatment options of prostate cancer with bone metastases, it also lays out the background for the individualized treatment plan that still needs to be further investigated.

Multiple modality treatment has been adapted for the treatment of various cancers,the outcome has been dramatically improved,but some of unique side effects due to the modalities like chemotherapy combined with radiotherapy have been observed in the clinic. Radiation recall dermatitis(RRD) is one of the side effects. In this paper,the etiology,clinical features,diagnosis,treatment and related factors of the radiation recall dermatitis are discussed.
7.The role of magnetic resonance spectroscopy imaging in tumor volume definition and clinic evaluation of radiation therapy
China Oncology 2001;0(05):-
Magnetic resonance spectroscopy(MRS)is an advanced medical imaging technique that can provide more accurate physiological and biochemical information than an MRI.MRS has more advantages in displaying abnormal physiological signs than the conventional MRI.A key problem in radiation therapy is the definition of the tumor target volume.MRS can define the tumor margin and range as well as predict the immediate response or side effects to radiotherapy.This paper summarized the role of MRS in tumor volume definition and clinical evaluation in radiation therapy.
8.Research advances in gold nanoparticle-mediated tumor radiosensitization
Chinese Journal of Radiation Oncology 2017;26(7):838-841
Nanotechnology has been extensively applied in the diagnosis and treatment of cancer, and is currently a major focus of research worldwide.Among the various nanomaterials, gold nanoparticles (GNPs) are of particular interest to many researchers due to their superior properties of low cytotoxicity, good biocompatibility, and preferential accumulation in tumors (the enhanced permeability and retention effect), which in turn gives GNPs a potential application in cancer diagnostics, imaging, photothermal therapy, and radiotherapy.Many published studies have shown that GNPs can be used as a new ideal radiosensitizer, and therefore understanding the radiosensitizing effects of GNPs both in vitro and in vivo will be of great significance in the clinical translation of nanomedicine.

Objective: To investigate clinical and hematological features of malignant lymphoma (ML) combined with venous thromboembolism (VTE). Methods:The clinical data of 65 patients with ML combined with VTE were collected between October 2010 and April 2014 and then retrospectively reviewed. Coagulation function and hemorheology were analyzed. Results:The proportion of males and females among patients with ML combined with VTE was 2.61:1. ML combined with VTE was mainly observed in patients with end-stage cancer. The highest incidence (81.54%) of ML combined with VTE was found in StageⅢB-Ⅳtumor. Among 65 patients with VTE, 43 (66.15%) were found after ML was diagnosed, 55 (84.62%) were deep vein thrombosis (DVT), 7 (10.77%) were pulmonary embolism (PE), and 3 (4.62%) were complicated with both DVT and PE. Common DVT locations were the upper limb and the neck vein of 37 cases (67.27%). Clinical manifestations of ML combined with DVT are limb pain, swelling, and increased skin temperature. Unexplained difficulty in breathing, chest pain, and syncope are also found in ML combined with PE. The total effective rate of 55 cases with DVT was 49.09%, and the rate of those cases with PE was 14.29%. The levels of platelet aggregation, D-dimer, high cut blood viscosity, low cut blood viscosity, plasma viscosity, hematocrit, assembly index of erythrocyte, and rigidity index of erythrocyte were significantly higher in patients with ML combined with VTE than in patients with ML alone;by contrast, APTT, erythrocyte sedimentation rate, deformability index of erythrocyte, and average velocity of blood flow were reduced in patients with ML combined with VTE than in patients with ML alone. Conclusion:DVT, which exhibits high incidence in males, is the most common type observed in ML combined with VTE. DVT is commonly manifested in the upper limb and the neck vein;furthermore, DVT is mainly observed in patients with end-stage cancer. Hematological indexes indicated changes in the sensitivity state of thromboembolism.
