PURPOSE: Exclusive enteral nutrition (EEN) therapy effectively induces clinical remission in Crohn's disease (CD). It remains unclear, however, whether partial enteral nutrition (PEN) can maintain remission. This study was performed to determine the abilities of oral EEN and oral PEN to induce and maintain clinical remission in pediatric patients with CD, respectively. MATERIALS AND METHODS: Pediatric patients with CD who received oral EEN at a single center in 2000-2014 were identified retrospectively. Remission rates of the EEN and PEN during the 2 years study period were determined. Risk factors for EEN and PEN failure were identified. RESULTS: Of the 66 patients who started EEN, 61 (92%) completed the course. Clinical remission was achieved in 88% (58/66) of the patients. All 58 patients with remission continued with PEN: 43 (74%) were treatment adherent. The cumulative remission rates at 1 and 2 years were 67% and 52%, respectively. Differing from EEN, limited therapeutic efficacy of PEN was shown in severe CD patients. Female gender associated significantly with non-adherence. CONCLUSION: Oral EEN and PEN effectively induced and maintained remission in a pediatric population. Non-adherence was a limiting factor in the success of therapy.

OBJECTIVETo investigate the capability of semi-quantitative and quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict the response to concurrent chemoradiotherapy( CCRT) in patients with non-small cell lung cancer (NSCLC).
METHODSA total of 24 patients with stage III or IIIB NSCLC, who underwent 3.0T DCE-MRI before CCRT, were enrolled in this study. Semi-quantitative and quantitative parameters were calculated by Funtool and Omnikinetics software. The relationship between these obtained parameters and tumor response was evaluated by Spearmen' s correlation analysis. The patients were classified into two groups according to the tumor regression rate after treatment, as response group (group A) and non-response group ( group B). Mann-Whitney U test was used to compare the parameters of responders and non-responders. The value of the parameters on predicting response was calculated by receiver operating characteristic curve (ROC).
RESULTSThe tumor regression rate after treatment was negatively correlated with time to peak (TTP) and the extravascular-extracellular volume fraction (Ve), and was positively correlated with signal enhancement ratio (SERmax) and volume transfer constant (Ktrans) (P < 0.05 for all). Statistical significant differences were found between group A and group B both in semi-quantitative and quantitative parameters (P < 0.05). Group A had a lower TTP value [(34.66 ± 16.37) s vs. (44.09 ± 17.41) s] and Ve value [(0.19 ± 0.03) vs. (0.25 ± 0.05)] than group B, whereas group A had a higher SERmax [(166.50 ± 44.95)% vs. (113.57 ± 46.62)%] and Ktrans [(0.41 ± 0.17) min(-1) vs. (0.28 ± 0.12) min(-1)] than group B (P < 0.05 for all). The ROC analysis indicated that when setting the threshold of Ve on ≤ 0.21 for predicting response, the specificity, sensitivity and accuracy were 85.7%, 80.0% and 83.3%, respectively, with an area under curve of 0.875 (P < 0.001).
CONCLUSIONSBoth the semi-quantitative and quantitative DCE-MRI parameters are helpful for predicting the response after CCRT of NSCLC. Quantitative parameters seem to be more meaningful than semi-quantitative parameters.

BACKGROUND AND OBJECTIVESingle mode of radiofrequency ablation (RFA) often leads to limited ablation in the zone of necrosis. This study clarifies the efficacy of combining temperature- and power-controlled RFA for malignant liver tumors.
METHODSBetween April 2008 and August 2008, 58 patients with malignant liver tumors received RFA at Sun Yat-sen University Cancer Center. The patients were divided into 2 groups using a random number table: one group received combined temperature- and power-controlled RFA (the combination group), and the other group received power-controlled RFA alone (the control group).
RESULTSThree patients were lost to follow-up and 55 patients were included for evaluation. Twenty-five patients with 29 tumors were treated by the combination RFA, and 27 tumors (93.1%) achieved either complete response (CR) or partial response (PR). One patient had a seriously decreased heart rate. In the control group, 30 patients with 32 tumors received power-controlled RFA, and 29 tumors (90.6%) achieved CR or PR. There were no serious complications. There was no difference between the combination and control groups in treatment time ((13.3 +/- 1.3) min vs. (10.2 +/- 2.3) min, P = 0.459). The number of sessions of RFA for the combination group was less than that of control group (1.3 sessions vs. 2.4 sessions), but the difference was not significant (P = 0.579).
CONCLUSIONRFA controlling both temperature and power is effective and safe for patients with malignant liver tumors, and the number of sessions of RFA for the combination group was less than that of the control group.

OBJECTIVETo investigate the efficacy of infliximab versus corticosteroids in achieving clinical remission in pediatric patients with Crohn's disease in China.
METHODData of all newly diagnosed active Crohn's disease pediatric cases seen from June 2009 to December 2013 in Children's Hospital, Zhejiang University School of Medicine were retrospectively recorded and reviewed.
INCLUSION CRITERIAthe age of the children was less than 18 years; pediatric Crohn's disease activity index (PCDAI) was more than 10; infliximab or corticosteroids were used for inducing remission; infliximab, immunosuppressive medications or mesalamine was prescribed for maintaining remission. Patients in steroids group were followed up for more than 1 year. The enrolled patients were divided into two groups: infliximab group and steroids group. Clinical data, laboratory findings and side effects of the medications were collected at week 2, 4, 12, 24 and 48. PCDAI and Crohn's disease endoscopic index score (CDEIS) were calculated. Clinical response rate, clinical remission rate, relapse rate, mucosal healing and growth were evaluated.
RESULTEleven children received infliximab therapy and 11 subjects received corticosteroids. In Infliximab group, 6, 5 and 7 patients were in clinical remission at week 2, 4, and 8, while so were 6, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00, 3.14, 0.92, P > 0.05). In infliximab group, 8, 8, and 11 patients were in clinical remission at week 2, 4, and 8, so were 8, 9, and 9 patients in steroids group. The difference was not statistically significant (χ² = 0.00,0.26, 2.20, P > 0.05). When compared with data at baseline, significant decreases were observed in the median PCDAI between the two groups at week 2, 4, and 8 (all P < 0.05). But there were no significant differences between two groups at week 2, 4, and 8 (all P > 0.05). At week 12, 24 and 48, 8/11, 7/8, 3/5 cases on infliximab versus 7/11, 9/11, 8/11 cases on steroids maintained remission. There was no significant differences between the two groups (all P > 0.05). In 7 patients and 9 patients remission was successfully induced at week 8. The relapse rate was similar at week 12, 24, and 48 (χ² = 0.83, 0.09, 1.00, all P > 0.05). Height for age Z score in infliximab group was significantly higher than that in steroids group at week 24 (P < 0.05). Body mass index Z score between the two groups at week 8, 24, and 48 were not statistically significant (all P > 0.05). Of the children treated with infliximab, 3 developed side effects. All the children treated with steroids got Cushing's syndrome.
CONCLUSIONIn children with Crohn's disease, infliximab therapy is as effective as corticosteroids to induce remission.Less side effects were observed with infliximab therapy compared with immunosuppressive medication and mesalamine.

Acute promyelocytic leukemia (APL) is a distinct subset of acute myeloid leukemia (AML) and is distinguished from other subsets of AML by its distinctive morphology, specific chromosomal abnormality, associated consumptive coagulopathy, and response to treatment. Interestingly, patients with APL frequently enter complete remission without undergoing a characteristic period of bone marrow hypoplasia. In two cases in this report, complete remission was achieved without bone marrow hypoplasia without further additional course of chemotherapy despite the appearance of persistent malignant cells in the bone marrow after first induction chemotherapy. During the period of treatment, severe coagulopathy occurred in both cases but resolved as the patients entered into remission. Remission in patients with APL may occur even when induction therapy fails to cause marrow hypoplasia or to eradicate replicative cells. To avoid unnecessary exposure to toxic therapy, caution should be exercised in assessing the adequacy of remission induction treatment.

OBJECTIVETo investigate the advantage of CT and MRI image fusion in determining the target precisely during 3-dimensional conformal radiotherapy for cranial carcinoma.
METHODSTwenty-five patients received CT and MRI examination simultaneously for localizing the tumor and defining target before 3-dimensional conformal radiotherapy. The target defined by MRI image was used as gross tumor volume, whereas CT value was used to calculate dose, making plan for radiotherapy. The difference between the target defined by CT and MRI was compared.
RESULTSAll the 25 patients underwent CT and MRI image fusion for localizing the tumor and defining the target in order to make anatomic symbol and surface symbol superposed. The number of tumor nodual detected by CT was as same as that found by MRI in 23 cases except two. Compared with the GTV defined by MRI image, it was larger in 10 cases by CT image, whereas smaller in 15 cases. The response rate assessed by MRI image was 64.0% (CR + PR) at the end of radiotherapy.
CONCLUSIONCT and MRI image fusion technique is more precise than either by CT or MRI alone in defining the GTV of 3-dimensional conformal radiotherapy for cranial carcinoma.

9.New Perspectives on Predictive Biomarkers of Tumor Response and Their Clinical Application in Preoperative Chemoradiation Therapy for Rectal Cancer.
Yonsei Medical Journal 2015;56(6):1461-1477
Preoperative chemoradiation therapy (CRT) is the standard treatment for patients with locally advanced rectal cancer (LARC) and can improve local control and survival outcomes. However, the responses of individual tumors to CRT are not uniform and vary widely, from complete response to disease progression. Patients with resistant tumors can be exposed to irradiation and chemotherapy that are both expensive and at times toxic without benefit. In contrast, about 60% of tumors show tumor regression and T and N down-staging. Furthermore, a pathologic complete response (pCR), which is characterized by sterilization of all tumor cells, leads to an excellent prognosis and is observed in approximately 10-30% of cases. This variety in tumor response has lead to an increased need to develop a model predictive of responses to CRT in order to identify patients who will benefit from this multimodal treatment. Endoscopy, magnetic resonance imaging, positron emission tomography, serum carcinoembryonic antigen, and molecular biomarkers analyzed using immunohistochemistry and gene expression profiling are the most commonly used predictive models in preoperative CRT. Such modalities guide clinicians in choosing the best possible treatment options and the extent of surgery for each individual patient. However, there are still controversies regarding study outcomes, and a nomogram of combined models of future trends is needed to better predict patient response. The aim of this article was to review currently available tools for predicting tumor response after preoperative CRT in rectal cancer and to explore their applicability in clinical practice for tailored treatment.

OBJECTIVETo summarize and analyze the clinicopathological features and surgical management of patients with pathologic complete response (pCR) in the primary tumor after neoadjuvant chemotherapy for rectal cancer, and to explore the rational treatment of this entity.
METHODSClinical data of fifty-two patients with locally advanced mid-low rectal cancer admitted to the Cancer Institute and Hospital, Chinese Academy of Medical Sciences from January 1994 to December 2013 were retrospectively analyzed. They were treated with neoadjuvant chemotherapy and achieved pathological complete response in the primary tumor. The preoperative clinical staging were stage II (cT3~4N0) in 10 cases and stage III (cT3~4N+) in 42 cases. After the neoadjuvant therapy, 10 cases achieved clinical complete response (cCR) (19.2%).
RESULTSRadical surgery was performed in 51 patients. Among them, five patients (9.8%) had pathological lymph node metastasis. One cCR patient underwent transanal local excision. The postoperative complication rate was 21.2%. During a median follow-up of 23.6 months, only one patient developed bone metastasis and another one had enlarged mesenteric and retroperitoneal lymph nodes detected by imaging. All the patients were alive by the last follow-up. The 2-year disease-free survival rate was 96.2% and overall survival rate was 100%.
CONCLUSIONSRadical surgery remains the standard therapy for cCR patients with rectal cancer after neoadjuvant chemotherapy. Local excision and "wait and see" should be recommended with great caution and limited to patients who cannot tolerate or refuse radical surgery with a strong demanding for sphincter saving, or applied in clinical trials.
