  • Background: Patients with refractory or relapsed multiple myeloma are considered to have a very poor prognosis, and new regimens are needed to improve the outcome. Gemcitabine, a nucleoside antimetabolite, is an analog of deoxycytidine which mainly inhibits DNA synthesis through interfering with DNA chain elongation and depleting deoxynucleotide stores, resulting in gemcitabine-induced cell death. Here we performed a systemic analysis to evaluate gemcitabine based chemotherapy as salvage treatment for patients with refractory and relapsed multiple myeloma. Methods: Clinical studies evaluating the impact of gemcitabine based regimens on response and safety for patients with refractory and relapsed multiple myeloma were identified by using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: In gemcitabine based regimens, 3 clinical studies which including 57 patients with refractory and relapsed multiple myeloma were considered eligible for inclusion. Systemic analysis suggested that, in all patients, pooled RR was 15.7% (9/57) in gemcitabine based regimens. Major adverse effects were hematologic toxicity, including grade 3 or 4 anemia, leucopenia and thrombocytopenia i. No treatment related death occurred with gemcitabine based treatment. Conclusion: This systemic analysis suggests that gemcitabine based regimens are associated with mild activity with good tolerability in treating patients with refractory or relapsed multiple myeloma.

  • 신경모세포종은 소아에서 발생하는 흔한 두개외 고형 종양 중 하나로서 진행된 경우 고용량 항암요법 및 자가 말초혈조혈모세포이식 후에도 재발이 잘 되어 예후가 매우 나쁘다. Iodine-131 metaiodobenzylguanidine ($^{131}I-MIBG$)는 치료에 잘 반응하지 않는 신경모세포종 4기 환자를 위한 대증적 치료 요법으로 제한적으로 이용되어 왔다. 저자들은 자가 말초혈조혈모세포이식 후 재발된 신경모세포종 3례에서 $^{131}I-MIBG$를 이용하여 통증을 경감시키고 생존 기간을 늘이는 고식적인 치료 효과를 얻어 이들에 대한 증례 보고를 하는 바이다.

  • Recently, fecal microbiota transplantation (FMT) has been attracting attention as a possible medical treatment of ulcerative colitis (UC). A randomized controlled trial of FMT for children with UC is currently underway. Therapeutic effects of FMT for adults with UC remain controversial. We report two cases of early-onset UC in children. A patient was diagnosed with UC at age 1-year 9-month and underwent FMT at age 2-year 3-month. He attained clinical remission for three weeks after FMT, but then relapsed at four weeks, ultimately undergoing a total colectomy. Another child was diagnosed with UC at 2-year 10-month and she underwent FMT at age 5 years. She has remained in clinical remission following FMT for 24 months and her UC has been maintained without complications with tacrolimus and azathioprine. We report that FMT for early-onset UC appears to be safe and potentially effective.

  • Over the past few decades, our understanding of the epidemiology and immunopathogenesis of Hodgkin lymphoma (HL) has made enormous advances. Consequently, the treatment of HL has changed significantly, rendering this disease of the most curable human cancers. To date, about 80% of patients achieve long-term disease-free survival. However, therapeutic challenges still remain, particularly regarding the salvage strategies for relapsed and refractory disease, which need further identification of better prognostic markers and novel therapeutic schemes. Although the precise molecular mechanism by which Epstein-Barr virus (EBV) contributes to the generation of malignant cells present in HL still remains unknown, current increasing data on the role of EBV in the pathobiology of HL have encouraged people to start developing novel and specific therapeutic strategies for EBV-associated HL. This review will provide an overview of therapeutic approaches for acute EBV infection and the classical form of HL (cHL), especially focusing on EBV-associated HL cases.

  • Objective: The purpose of this study was to evaluate the effectiveness of middle meningeal artery embolization (MMAE) in elderly high-risk patients with symptomatic chronic subdural hematoma (CSDH) in terms of reduction in hematoma volume and recurrence rate. Methods: We retrospectively reviewed data prospectively collected from nine patients who underwent 13 MMAE for CSDH between June 2017 and May 2022. The volume of the subdural hematoma was measured using a computer-aided volumetric analysis program. Hematoma volume changes during the follow-up period were analyzed and clinical outcomes were evaluated. Results: The mean follow-up period was 160 days (range, 46-311 days). All procedures were technically successful and there were no procedure-related complications. Of the 13 MMAE, 84% (11 out of 13 hemispheres) showed mean 88% of reduction on follow-up volumetric study with eight cases of complete resolution. There was one refractory case with MMAE which had been performed multiple burr-hole trephinations, for which treatment was completed by craniotomy and meticulous resection of multiple pseudomembranes. There was no recurrent case during the follow-up period, except for refractory case. Conclusions: MMAE for CSDH in selected high-risk elderly patients and relapsed patients might be effective. Despite the small cohort, our findings showed a high rate of complete resolution with no complications. Further prospective randomized trials are warranted to evaluate its usefulness as a primary treatment option for CSDH.
