Objective: To explore the application value of matrix assisted laser desorption time of flight mass spectrometry (MALDI-TOF-MS) inproteomics of HBV-related liver cancer. Methods: Thirty patients with HBV-related liver cancer, and 25 healthy volunteers were selected from January2018 to June 2018 in our hospital. The serum proteins of these participantswere captured by weak cation exchange (WCX) beads. MALDI-TOF-MS and related software were used to analyze the proteins, detect the marker of serum proteins in HBV-related liver cancer, establish the liver cancer diagnosis model and perform blind test. Results: Totally 81 protein peaks were screened out, and 27 protein peaks had significant difference (P<0.05), of which 17 were up-regulated, 10 were down-regulated. Three differential protein peaks (M/Z 9179.55, 7789.00, 4097.00) were screened by BPS5.0 software to establish the model. Further blind test showed that the sensitivityand specificity of the protein peaks were 90.91% and 77.78%, respectively. Conclusions MALDI-TOF-MS provided an important basis for the diagnosis and treatment of HBV-related liver cancer.

Objective: To evaluate the choice of surgical treatment of ductal carcinoma in situ (DCIS) and its impact on long-term outcomes. Methods: A retrospective analysis of the clinicopathological features and treatment protocol of DCIS patients who underwent surgical treatment in Comprehensive Breast Health Center, Ruijin Hospital, Shanghai Jiaotong University School of Medicine from January 2009 to August 2016 was done. The factors which could affect surgical treatment were analyzed by χ² test and Logistic regression. Survival analysis were performed between different surgical approaches. Kaplan-Meier survival curves and Log-rank tests demonstrated the distribution of disease free survival and overall survival. Results: A total of 526 patients were enrolled in this study, 405 cases (77.0%) underwent mastectomy, 121 cases (23.0%) underwent breast-conserving surgery, of which 88 cases received radiotherapy after breast-conserving surgery. It was shown by univariate and multivariate analysis that age>50 years (OR=0.631, 95% CI: 0.413 to 0.965, P=0.034), first symptom of nipple discharge (OR=0.316, 95% CI: 0.120 to 0.834, P=0.020), excision biopsy (OR=1.831, 95% CI: 1.182 to 2.835, P=0.007) and tumor size >3 cm (OR=0.422, 95% CI: 0.206 to 0.864, P=0.018) were significantly correlated with choice of surgical treatment for breast lesions. Axillary lymph node dissection was performed for 118 cases (22.4%), with sentinel lymph node biopsy for 327 cases (62.2%), and none for 81 cases (15.4%). There was significant statistical difference in the choice of axillary lymph node management in patients of different age (χ²=8.124, P=0.017), biopsy type (χ²=35.567, P=0.000), breast operation type (χ²=149.118, P=0.000) and tumor size (χ²=13.394, P=0.010). The 5-year disease free survival rates was 95.7%, 89.6% and 100%, respectively, for mastectomy group, breast-conserving surgery group and breast-conserving surgery plus radiotherapy group. And the 5-year overall survival rates for three groups were 99.0%, 100% and 100%. The differences were not statistically significant (P=0.427, 0.777). Conclusions For DCIS patients, age, first symptom and tumor size are independent predictors of breast surgery. The choice of axillary lymph node surgery is influenced by age, biopsy, operation type, and tumor size. Different surgical treatment options has no significant effect on disease-free survival and overall survival in DCIS patients.

Objective To design and implement a planning backup and restore system and evaluate its clinical effectiveness.Methods The default TPS menu of data save (File-Save) and system exit (File -Exit) was replaced by user designed script (Script_Save and Script_Exit) which backup the current planning status in a special format besides performing the normal save and exit operation.The treatment plan can be rolled back to any previously saved backup status in case the data were damaged or,the plan quality was deteriorated in the try and error planning process.Results The save and exit operation was simplified by using the user designed script.An extra disk space of 59.4MB per patient was required to backup the planning process and the backup was performed with no impact to the normal planning operation.1.9％ of the plans were restored during the planning process.For all of the restoring operations,65％ were performed within 1 day,80％ were performed within 1 week,and 87.6％ were performed within 1 month.Some restoring operations were even performed 4 months after the planning.Conclusions The designed backup and restore system is clinical applicable and valuable.Clinical using of the system can improve the planning efficiency and patient data safety.

PURPOSE: The purpose of this study was to investigate the changes of tumor infiltrating lymphocytes (TILs) between core needle biopsy (CNB) and surgery removed sample (SRS) in early stage breast cancer patients and to identify the correlating factors and prognostic significance of TILs changes. MATERIALS AND METHODS: A retrospective study was carried out on 255 patients who received CNB and underwent surgical resection for invasive breast cancer. Stromal TILs levels of CNB and SRS were evaluated respectively. Tumors with ≥50% stromal TILs were defined as lymphocyte-predominant breast cancer (LPBC). Clinicopathological variables were analyzed to determine whether there were factors associated with TILs changes. Log-rank tests and Cox proportional hazards models were used to analyze the influences of TILs and TILs changes on survival. RESULTS: SRS-TILs (median, 10.0%) were significant higher than CNB-TILs (median, 5.0%; p<0.001). Younger age (<60 years, p=0.016) and long surgery time interval (STI, ≥4 days; p=0.003) were independent factors correlating with higher TILs changes. CNB-LPBC patients showed better breast cancer-free interval (BCFI, p=0.021) than CNB-non-LPBC (CNB-nLPBC) patients. Patients were categorized into four groups according to the LPBC change pattern from CNB to SRS: LPBC→LPBC, LPBC→nLPBC, nLPBC→LPBC, and nLPBC→nLPBC, with estimated 5-year BCFI 100%, 100%, 69.7%, and 86.0% (p=0.016). nLPBC→LPBC pattern was an independent prognostic factor of worse BCFI (hazard ratio, 2.19; 95% confidence interval, 1.06 to 4.53; p=0.035) compared with other patterns. CONCLUSION: TILs were significantly higher in SRS than in CNB. Higher TILs changes were associated with younger age and long STI. Changing from nLPBC to LPBC after CNB indicated a worse BCFI, which needs further validation.

Objective:To establish an automatic planning method using volumetric-modulated arc therapy (VMAT) for primary liver cancer (PLC) radiotherapy based on predicting the feasibility dose-volume histogram (DVH) and evaluate its performance.Methods:Ten patients with PLC were randomly chosen in this retrospective study. Pinnacle Auto-Planning was used to design the VMAT automatic plan, and the feasibility DVH curve was obtained through the PlanIQ dose prediction, and the initial optimization objectives of the automatic plan were set according to the displayed feasible objectives interval. The plans were accessed according to dosimetric parameters of the planning target volume and organs at risk as well as the monitor units. All patients′ automatic plans were compared with clinically accepted manual plans by using the paired t-test. Results:There was no significant difference of the planning target volume D 2%, D 98%, D mean or homogeneity index between the automatic and manual plans ((58.55±2.81) Gy vs.(57.98±4.17) Gy, (47.15±1.58) Gy vs.(47.82±1.38) Gy, (53.14±0.95) Gy vs.(53.44±1.67) Gy and 1.15±0.05 vs. 1.14±0.07, all P>0.05). The planning target volume conformity index of the manual plan was slightly higher than that of the automatic plan (0.77±0.08 vs. 0.69±0.06, P<0.05). The mean doses of normal liver, V 30Gy, V 20Gy, V 10Gy, V 5Gy and V< 5Gy of the automatic plan were significantly better than those of the manual plan ((26.68±11.13)% vs.(28.00±10.95)%, (29.96±11.50)% vs.(31.89±11.51)%, (34.88±11.51)% vs.(38.66±11.67)%, (45.38±12.40)% vs.(50.74±13.56)%, and (628.52±191.80) cm 3vs.(563.15±188.39) cm 3, all P<0.05). The mean doses of the small intestine, the duodenum, and the heart, as well as lung V 10 of the automatic plan were significantly less than those of the manual plan ((1.83±2.17) Gy vs.(2.37±2.81) Gy, (9.15±9.36) Gy vs.(11.18±10.49) Gy, and (5.44±3.10) Gy vs.(6.25±3.26) Gy, as well as (12.70±7.08)% vs.(14.47±8.11)%, all P<0.05). Monitor units did not significantly differ between two plans ((710.67±163.72) MU vs.(707.53±155.89) MU, P>0.05). Conclusions:The automatic planning method using VMAT for PLC radiotherapy based on predicting the feasibility DVH enhances the quality for PLC plans, especially in terms of normal liver sparing. Besides, it also has advantages for the protection of the intestine, whole lung and heart.
