The aim of this study was to investigate the early outcome of Endostar combined with chemoradiotherapy for advanced cervical cancer. Fifty-two cases (FIGO IIb to IVa) were divided randomly into two groups, receiving chemoradiotherapy alone (CRT group) and Endostar combined with chemoradiotherapy (CRT+E group). For the patients in the CRT+E group, Endostar was administered daily with the dosage of 7.5 $mg/m^2$, and cisplatin was administered weekly with the dosage of 20 $mg/m^2$ during the radiation. The regimens lasted for 4 weeks with no difference in chemoradiotherapy between the two groups. The early outcome complete remission rate was 73.1%, partial remission rate was 23.1% and the total response rate was 96.2% in CRT+E group, a significant improvement on the 34.6%, 42.3% and 76.9%, respectively, in the CRT group. One year survive rates were 100% and 84.6% in the CRT+E group and CRT groups, the difference being significant. Endostar combined with chemoradiotherapy can improve the early outcome of the advanced cervical cancer, and adverse effects were not encountered.

Purpose: The efficacy of exclusive enteral nutrition (EEN) with a polymeric diet has not been confirmed in Korean pediatric patients with Crohn's disease (CD). This study aimed to compare the effectiveness of EEN with a specific polymeric diet ($Encover^{(R)}$) and corticosteroids (CSs) for the induction of remission in Korean pediatric CD patients. Methods: We retrospectively compared data from 51 pediatric CD patients who underwent induction therapy with EEN (n=19) or CSs (n=32) at Severance Children's Hospital or Incheon St. Mary's Hospital in Korea. The primary endpoint of this study was the rate of clinical remission, defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score <10, after 8 weeks of induction treatment. Clinical, laboratory, and growth data at post-induction as well as their changes from baseline were also compared between groups. Results: After 8 weeks of induction therapy, clinical remission rates were 78.9% (15/19) and 65.6% (21/32) in the EEN and CS groups, respectively (p=0.313). No significant differences in PCDAI scores, laboratory variables, and growth parameters were noted between the two groups at post-induction. However, significant changes in albumin levels at post-induction were observed in the EEN group compared to the CS group (p=0.038). Conclusion: Our results suggest that the effectiveness of EEN with a polymeric diet and CSs for induction therapy did not differ in Korean pediatric CD patients. EEN with a polymeric diet is a good first-line treatment option for the induction of remission in these patients.

Background/Aims: Colonic stenting as a bridge to elective surgery is an alternative for emergency surgery in patients with acute malignant colonic obstruction. However, since its benefits are uncertain, we aimed to establish whether it has better clinical outcomes. Methods: The patients with acute malignant left-sided colon obstruction enrolled from January 2009 to December 2018 in National Health Insurance Service Ilsan Hospital. The patients were enrolled to undergo colonic stenting as a bridge to elective surgery or emergency surgery. The following oncological outcomes were assessed: incidence of complete remission, disease progression, local recurrence, and systemic recurrence. Results: Out of 40 patients, 33 received self-expanding metallic stent (SEMS) as a bridge-to-surgery, and 7 underwent emergency surgery. More stoma was made in case of emergency surgery with statistical significance (p < 0.001). There were no significant differences in complete remission rate in curable left-sided malignant colonic obstruction between SEMS as a bridge-to-surgery and emergency surgery. Complete remission was achieved for 3 patients (42.9%) in the non-stent group and 27 patients (81.8%) in the stent group. There was no statistically significant difference in oncologic outcomes between the two groups (p = 0.069). According to multi-variate analysis, advanced TNM stage, Adjuvant chemotherapy, and SEMS bridge-to-surgery were significantly associated with disease-free survival. Disease-free survival rate differed significantly between the two groups (p = 0.024). Conclusions: SEMS as a bridge-to-surgery might be an effective strategy and reduce stoma formation in acute malignant left-sided colon obstruction.

Since the successful introduction of all-trans-retinoic acid (ATRA) and its combination with anthracycline-containing chemotherapy, the prognosis for acute promyelocytic leukemia (APL) has markedly improved. With ATRA and anthracycline-based-chemotherapy, the complete remission rate is greater than 90%, and the long-term survival rate is 70-89%. Moreover, arsenic trioxide (ATO), which was introduced for APL treatment in 1994, resulted in excellent remission rates in relapsed patients with APL, and more recently, several clinical studies have been designed to explore its role in initial therapy either alone or in combination with ATRA. APL is a rare disease in children and is frequently associated with hyperleukocytosis, which is a marker for higher risk of relapse and an increased incidence of microgranular morphology. The frequency of occurrence of the promyelocytic leu-kemia/retinoic acid receptor-alpha (PML/$RAR{\alpha}$) isoforms bcr 2 and bcr 3 is higher in children than in adults. Although recent clinical studies have reported comparable long-term survival rates in patients with APL, therapy for APL in children is challenging because of the risk of early death and the potential long-term cardiac toxicity resulting from the need to use high doses of anthracyclines. Additional prospective, randomized, large clinical trials are needed to address several issues in pediatric APL and to possibly minimize or eliminate the need for chemotherapy by combining ATRA and ATO. In this review article, we discuss the molecular pathogenesis, diagnostic progress, and most recent therapeutic advances in the treatment of children with APL.

Objective: This study aimed to investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma (HB) and the factors affecting prognosis. Methods: A total of 35 children underwent multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. The patients were followed up every month. Results: Serum AFP levels in 33 out of 35 patients in this study were significantly increased (P = 0.0002). According to the statistical scatter plot, the values of serum AFP on the 25th, 50th, and 75th percentages were 1,210, 1,210 and 28,318 ng/dl, respectively. Of the 35 cases, 21 were stage IV. 18 cases were treated with systemic chemotherapy before surgery, and 3 cases with locally interventional chemotherapy before surgery. Statistical analysis showed that the preferred interventional treatment affected prognosis, and that there was a statistically significant difference (P = 0.024). Some 33 patients completed the follow-up, of which 17 were in complete remission (CR), 5 were in partial remission (PR), 1 became disease progressive (DP), and 10 died. The remission and overall survival rates were 66.7% (22/33) and 69.7% (23/33), respectively. Patients with the mixed HB phenotypes had worse prognoses than the epithelial phenotype (P < 0.001), and patients in stage IV had a lower survival rate than those in stage III (P < 0.001). Conclusion: Multimodality treatment can effectively improve remission rate and prolong the survival of children with advanced HB. In addition, alpha-fetoprotein (AFP), a tumor marker of liver malignant tumors, HB pathological classification, and staging are highly useful in predicting prognosis.

식도암은 다른 암종에 비해서 예후가 좋지 못하며, 최근 외과적 수술의 근치적 절제율의 발달과 항암화학방사선동시요법이 효과적이라는 보고들은 있으나, 진행성 식도암의 경우에 있어서는 부분관해에 이르는 것이 대부분이며, 한계가 있는 것이 사실이다. 저자들은 80세 남자가 한 달 전부터 발생한 연하곤란을 주소로 내원하였으며, 식도암 및 암종의 주기관지로의 함입, 다발성의 전이성 림프절 비대를 보여 진행성 식도암으로 진단을 받았다. 그러나 환자가 고령이라는 점, 전신상태가 좋지 못한 점, 식도암이 주기관지까지 함입되어 있어 방사선치료 후 누공이 발생할 가능성 등을 염두하여 고식적인 항암화학요법만을 시행하였으나, 총 6차에 걸친 항암화학요법 후에 완전 관해에 이른 드문 증례를 경험하였다.

Although most children with idiopathic nephrotic syndrome respond to corticosteroid therapy, many responders show steroid dependency and frequent relapse. In these children, one of the major problems is the serious side effects resulting from continuous steroid therapy. Thus, this study was conducted to assess the therapeutic efficacy and safety of six-month cyclosporine treatment with the low-dose deflazacort therapy in children with nephrotic syndrome. Thirty children with steroid dependence (SD), frequent relapse (FR) and steroid resistance (SR) were enrolled in this study. They were treated with 6-month oral cyclosporine $(Cypol-N^{(R)})$ plus the low-dose deflazacort $(Calcort^{(R)})$ therapy at Samsung Medical Center from September 2002. The dosage of cyclosporine was started at 5 mg/kg/day and was monthly adjusted to maintain clinical remission and/or a trough blood level, while deflazacort dosage was reduced gradually. Clinical evaluation and monitoring of cyclosporine toxicity were performed every $2\sim4$ weeks. Outcomes were compared to the latest sir-month period of steroid only therapy before cyclosporine treatment. Student's t-test and ANOVA were used for statistical analysis. Out of 28 children with SD and FR, 23 $(82.1\%)$ sustained remission, and 5 $(17.9\%)$ experienced 1 or 2 relapses during therapy. Out of 2 children with SR, 1 child sustained remission, and 1 child showed no response. The mean duration of remission and occurrence of relapse were significantly improved (p <.0001). In addition, the mean dosage of steroid was significantly reduced (p=.003). Although a number of adverse effects occurred in this study, they were not so serious as to necessitate discontinuation of the therapy. No nephrotoxicity was observed. Twenty out of the 28 children who had been in remission relapsed after withdrawal of cyclosporine. Fifteen of these children showed relapse within a month. These results demonstrated that the combination of cyclosporine with the low-dose deflazacort was efficient and safe in children with SD and FR during the six-month treatment. However, further studies are necessary in order to resolve the problem of high relapse rate after discontinuation of cyclosporine.

Background: We designed this randomized controlled trial (RCT) to assess whether lobaplatin-based concurrent chemotherapy might be superior to cisplatin-based concurrent chemotherapy for FIGO stage II and III cervical cancer in terms of efficacy and safety. Materials and Methods: This prospective, open-label RCT aims to enroll 180 patients with FIGO stage II and III cervical cancer, randomly allocated to one of the three treatment groups (cisplatin $15mg/m^2$, cisplatin $20mg/m^2$ and lobaplatin $35mg/m^2$), with 60 patients in each group. All patients will receive external beam irradiation (EBRT) and high-dose-rate intracavitary brachytherapy (HDR-ICBT). Patients in cisplatin $15mg/m^2$ and $20mg/m^2$ groups will be administered four cycles of $15mg/m^2$ or $20mg/m^2$ cisplatin intravenously once weekly from the second week to the fifth week during EBRT, while patients inthe lobaplatin $35mg/m^2$ group will be administered two cycles of $35mg/m^2$ lobaplatin intravenously in the second and fifth week respectively during pelvic EBRT. All participants will be followed up for at least 12 months. Complete remission rate and progression-free survival (PFS) will be the primary endpoints. Overall survival (OS), incidence of adverse events (AEs), and quality of life will be the secondary endpoints. Results: Between March 2013 and March 2014, a total of 61 patients with FIGO stage II and III cervical cancer were randomly assigned to cisplatin $15mg/m^2$ group (n=21), cisplatin $20mg/m^2$ group (n=21) and lobaplatin $35mg/m^2$ group (n=19). We conducted a preliminary analysis of the results. Similar rates of complete remission and grades 3-4 gastrointestinal reactions were observed for the three treatment groups (P=0.801 and 0.793, respectively). Grade 3-4 hematologic toxicity was more frequent in the lobaplatin group than the cisplatin group. Conclusions: This proposed study will be the first RCT to evaluate whether lobaplatin-based chemoraiotherapy will have beneficial effects, compared with cisplatin-based chemoradiotherapy, on complete remission rate, PFS, OS, AEs and quality of life for FIGO stage II and III cervical cancer.
