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.

Mycosis fungoides is the most common type of cutaneous T-cell lymphoma. Patients with early stage disease usually respond well to conventional therapies, with a relatively favorable prognosis. However, a few patients are refractory to treatment and need alternative strategies, even at the patch and plaque stages. We report the case of a middle-aged woman with long-standing and refractory mycosis fungoides that responded to combination therapy with the 308-nm excimer laser and oral alitretinoin.

위에 발생하는 암 중 위 림프종이 1-6% 가량을 차지하고 있고, 이 중 50% 가량이 MALT 림프종이다. MALT 림프종의 60-70% 가량은 조기, 국소병기에서 진단된다. 위 MALT 림프종은 일반적으로 그 진행이 매우 느리며 상복부 통증, 소화불량, 오심, 구토 등의 비특이적인 증상을 보인다. 진단은 조직학적으로 진단하며, 헬리코박터필로리 연관 만성 위염에서 보이는 염증성 병변과의 감별을 위해 Wotherspoon score를 이용한다. 여러 연구를 통해 위 MALT 림프종이 헬리코박터필로리 감염과 관련이 있다는 것이 밝혀져 있고, 3세염색체증, 18세염색체증, t(11;18), t(1;14), t(14;18), t(3;14) 등 여러 유전적 이상을 가질 수 있는 것으로 알려져 있다. 적절한 치료 방침을 결정하기 위해 병기를 결정하는 것은 매우 중요하며, Lugano International Conference classification을 주로 사용한다. 위 MALT 림프종의 1차 치료는 헬리코박터필로리 감염 유무 및 병기와 관계없이 헬리코박터필로리 제균치료이다. Stage I/II1 환자의 경우 제균치료로 60-90%의 완전 완화율을 보인다. 제균치료에 반응이 없는 경우에는 방사선치료, 항암화학요법, 면역치료 등을 시행해 볼 수 있고, 75-100%의 완전완화율을 보인다. 향후 헬리코박터필로리의 감염율이 감소하면서 위 MALT 림프종의 발생도 감소할 것으로 기대된다. 또한 향후 치료방침 확립을 위해 지속적인 연구가 필요할 것으로 생각한다.

Pulmonary mucormycosis is an uncommon opportunistic fungal infection associated with diabetis mellitus, leukemia, lymphoma & other debilitating diseases. Their clinical presentations depend on the associated underlying disorders. Generally patients with leukemia and lymphoma often have rapidly progressive clinical course, and may cause diffuse parenchymal disease refractory to medical and surgical therapies. However, some diabetics with pulmonary mucormycosis have a striking tendency to develop a localized endobronchial disease in major airway which is amenable to therapy with surgery and Amphotericin B. We have experienced a case of endobronchial mucormycosis complicating lung abscess associated with diabetic ketoacidosis, which was cured without specific antifungal therapy or surgery. A brief review of the literature was given.

Background: ABVD (doxorubicin, bleomycin, vinblastine (Vb) and dacarbazine) is the standard regimen in Hodgkin's lymphoma (HL).Vincristine (O) is a mitotic spindle agent like Vb. We aimed to evaluate the efficacy and safety of O as a part of ABOD in HL. Materials and Methods: Patients who had ABOD were enrolled. Stage I-II HL were evaluated for unfavorable risk factors according to NCCN. National Cancer Institute Common Toxicity Criteria was used for toxicity. Results: Seventy-nine HL patients in our center between 2003 and 2007 were evaluated retrospectively. Median follow-up was 54 months. Most of the patients were male in their third decade. Median ABOD cycles were 6 (2-8). Primary refractory disease rate was 17.7% whereas it was 5.1% for early relapse and 5.1% for late relapse disease. Response rates were as 82.3% for complete response, 11.4% for partial response, 5.1% for stable disease and 1.3% for progressive disease. Half of relapsed patients had autologous stem cell transplantation. Estimated 5-year failure-free survival was 71% and significantly longer in early stage patients without risk factors, bulky disease or radiotherapy (RT) (p=0.05, p<0.0001, p=0.02; respectively). Estimated 5-year overall survival was 74% and significantly longer in those who had no RT (p=0.001). Dose modification rate was 5.1% and chemotherapy delay rate was 19%. There were no toxicity-related deaths. Conclusions: ABOD seems to be effective with managable toxicity in HL, even in those with poor prognostic factors.

Purpose: To assess the clinical outcomes of radiotherapy (RT) using two-dimensional (2D) and three-dimensional conformal RT (3D-CRT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma to evaluate the effectiveness of involved field RT with moderate-dose and to evaluate the benefit of 3D-CRT comparing with 2D-RT. Materials and Methods: Between July 2003 and March 2015, 33 patients with stage IE and IIE gastric MALT lymphoma received RT were analyzed. Of 33 patients, 17 patients (51.5%) were Helicobacter pylori (HP) negative and 16 patients (48.5%) were HP positive but refractory to HP eradication (HPE). The 2D-RT (n = 14) and 3D-CRT (n = 19) were performed and total dose was 30.6 Gy/17 fractions. Of 11 patients who RT planning data were available, dose-volumetric parameters between 2D-RT and 3D-CRT plans was compared. Results: All patients reached complete remission (CR) eventually and median time to CR was 3 months (range, 1 to 15 months). No local relapse occurred and one patient died with second primary malignancy. Tumor response, survival, and toxicity were not significantly different between 2D-RT and 3D-CRT (p > 0.05, each). In analysis for dose-volumetric parameters, $D_{max}$ and CI for PTV were significantly lower in 3D-CRT plans than 2D-RT plans (p < 0.05, each) and $D_{mean}$ and V15 for right kidney and $D_{mean}$ for left kidney were significantly lower in 3D-CRT than 2D-RT (p < 0.05, each). Conclusion: Our data suggested that involved field RT with moderate-dose for gastric MALT lymphoma could be promising and 3D-CRT could be considered to improve the target coverage and reduce radiation dose to the both kidneys.

전신방사선조사를 시행할 때 우선적으로 해결되어야 할 과제는 총선량의 결정과 머리, 목, 폐, 복부, 골반과 다리등 모든 부위에 동일한 선량을 조사하는 것이다. 본 연구에서는 머리, 목, 폐등 밀도와 두께에 따른 선량보정을 A1으로 만든 조직보상체를 이용하는 미네소타대학 방법(방법 1) 과 소아들이 장시간 동안 편안한 자세로 움직이지 않고 치료받을수 있도록 본원에서 개발한 고정치료틀에 조직등가물질로 머리, 목, 폐등을 보정한 방법(방법 2)의 선량분포를 비교검토하였다. 방법 1에서는 95.6％에서 100％의 선량분포를 보였으며, 방법 2 에서는 95.4％에서 100％의 선량분포를 보였다. 또한 방법 2 에서 중심 부위와 표면 부위의 선량분포는 머리 부위에서 103.4％, 목 부위에서 101.5％, 배꼽 부위에서 102.3％를 나타내었다.
