  • I, II기 원방성 위장관 임파종 환자 38명의 수술후 방사선 치료 결과를 분석하였다. 방사선 치료 중 6예의 원격전이가 관찰되었고, 방사선 치료 전 병소의 크기에 따른 치료실패율은 5cm 미만에서 $31\%$, 5cm 이상에서 $75\%$로 유의한 차이가 있었다(p<0.05). 방사선 치료를 계획대로 받은 28예서 5년 생존율은 $69.2\%$였고, 그중 병소의 크기가 5cm 미만인 경우는 $72\%$였다. 병소의 크기에 따른 5년 무병생존율에도 차이가 있어 5cm 미만인 경우엔 $71\%$, 5cm 이상인 경우엔 $25\%$였다(p<0.05). 반면에 병기, 병리학적 유형 및 원발장기 등에 따른 생존율의 차이는 유의하지 않았다. 따라서 방사선 치료 전 병소 크기가 5cm 미만일 경우는 완치가 가능하나, 5cm 이상으로 클 경우에는 항암화학요법의 병용이 시도될 수 있겠다.

  • Background: This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. Materials and Methods: We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Results: Of the 289 lymph node biopsy specimens received, 154 (53.3%) were from males and 135 (46.7%) from females giving a male: female ratio of 1.14:1. Age of the patients ranged from 2.5 to 96 years with a mean age 33.9 years. The commonest lymph node group affected was the cervical (30.4%) followed by axillary (9.7%) and inguinal (8.7%). Malignant lymphoma [71 Hodgkin's disease (HD), 57 non Hodgkin's lymphoma (NHL)] 128 (44.3%), reactive hyperplasia 68 (23.5%), and tuberculosis 41 (14.2%) were the common causes of lymph node enlargement. While HD, reactive hyperplasia and tuberculosis were commonest in young adult patients (10-29 years old) and rare above the age of 50 years; NHL was the predominant cause of lymph node enlargement above 50 years. Conclusions: Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, lymphomas were the most common (44.3%) followed by non-specific reactive hyperplasia (23.5%) and tuberculous lymphadenitis (14.2%).

  • Natural Killer/T-cell(NK/TC) lymphoma is a rare disease of oral and maxillofacial region with an aggressive clinical course, showed unusual clinical manifestations. Prognosis is generally poor and the disease is invariably fatal after systemic dissemination. A case of nasal NK/TC non-Hodgkin's lymphoma in the left maxilla that showed unusual clinical manifestations and a fulminant course of disease, are described with literature reviews. A 81-year-old female patient presented with rapidly growing ulceration and general malaise after extraction of right upper second premolar NK/TC lymphoma was subsequently detected by biopsy. rapid and wide invasion from maxilla to mandible developed within 10 days and multiple metastasis to whole body was after a few weeks. Although the time relationship is not clear, local invasion and multiple metastasis could be dissemination from localized disease of NK/TC. As seen in my case, the course can be excessively aggressive and fulminant even though it first appeared as a localized ulceractive lesion. She is expired 2 months after biopsy. Positivity of immunohistochemical stain (CD56, LCA, UCHL-1, CD3), which is a specific characteristic of NK/TC, may serve as a factor showing a poor prognosis of a malignant lymphoma

  • Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently spotlighted T-cell origin non-Hodgkin's lymphoma with an increasing incidence of over 800 cases and 33 deaths reported worldwide. Development of BIA-ALCL is likely a complex process involving many factors, such as the textured implant surface, bacterial biofilm growth, immune response, and patient genetics. As the incidence of BIA-ALCL is expected to increase, it is important for all surgeons and physicians to be aware of this disease entity and acquire thorough knowledge of current evidence-based guidelines and recommendations. Early detection, accurate diagnosis, and appropriate treatment are the foundations of current care.

  • Two cases of primary malignant lymphoma of the brain and six cases of secondary CNS lymphoma seen at Yonsei cancer center, radiotherapy department for recent 4 years are presented. Primary lymphomas revealed single tumor mass on corpus callosum area and secondary lymphoma were intracranial (3 cases) or leptomeningeal type (3 cases). Histology of primary lymphoma were reticulum cell sarcoma and secondary lymphomas were either diffuse histiocytic or diffuse poorly differentiated lymphocytic lymphoma. All patients showed good response to radiation. Two patients with primary CNS lymphoma and two of six secondary CNS lymphoma are alive after radiotherapy (34, 31, 26, 12 months). But the prognosis of secondary CNS lymphoma is grave, because of progressive systemic disease. Incidence, risk factors, diagnosis and therapeutic management of CNS involvement are also discussed.

  • Testing normality is very important because the most common assumption is normality in statistical analysis. We propose a new plot and test statistic to goodness-of-fit test for normality based on the generalized Lorenz curve. We compare the new plot with the Q-Q plot. We also compare the new test statistic with the Kolmogorov-Smirnov (KS), Cramer-von Mises (CVM), Anderson-Darling (AD), Shapiro-Francia (SF), and Shapiro-Wilks (W) test statistic in terms of the power of the test through by Monte Carlo method. As a result, new plot is clearly classified normality and non-normality than Q-Q plot; in addition, the new test statistic is more powerful than the other test statistics for asymmetrical distribution. We check the proposed test statistic and plot using Hodgkin's disease data.

  • Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of malignant lymphoma (ML), accounting for only 1 to 2% of all non-Hodgkin's lymphoma (NHL). Although ML of the parotid gland is rare, the majority are B-cell types. The AITL occurring synchronously in the parotid gland and lateral neck has not been reported earlier. It is classified as a high-grade malignancy with aggressive clinical features, and the prognosis is worse than any other type of NHL. We recently encountered a 72-year-old man with multiple mass on the ipsilateral parotid tail and lateral neck, and he was finally diagnosed as AITL. We report the unique and rare disease entity with a brief literature review.

  • 목적 : 두경부에 국한된 1기, 2기 대세포성(diffuse large cell) 비호치킨 림프종의 항암화학방사선 병용요법 시 방사선 조사영역 내의 재발을 예방하기 위한 적정 방사선 조사선량을 알아보고자 하였다. 대상 및 방법 : 1985년 5월부터 1998년 12월까지 국한성 두경부 대세포성 림프종으로 항암화학요법 후 방사선치료를 받은 53명을 대상으로 하였다. 나이는 13세부터 69세까지였으며 중앙값은 49세였다. 남녀 비는 1.65대 1이었고 1기, 2기 환자가 각각 27명, 26명이었다. 종양 크기별로 5 cm 미만이 30명, 5 cm 이상이 23명이었다. 원발부위는 경부림프절 22명, 편도 20명, 비인두 4명, 설기저부 3명, 부비동 2명, 후두 1명, 연구개 1명이었다. 항암화학요법은 1명을 제외하고 3회 이상 시행되었으며 방사선치료는 48명이 원발부위와 경부임파선을, 5명이 원발부위만 치료하였다. 생존율, 무병생존율, 조사영역 내 무재발생존율과 방사선 조사선량에 따른 방사선 조사영역 내에서의 재발빈도를 조사하였다. 결과 : 항암화학요법 후 44명$(83\%)$이 완전관해 되었고 연이은 방사선치료 후 53명 모두 완전관해 되었다. 12명$(23\%)$이 재발하였고 그중 2명은 방사선 조사영역 내 재발이었고 방사선 조사영역 바깥 재발은 11명으로 복강 및 골반내 림프절이 가장 많았다. 방사선 조사선량 별 조사영역 내 재발은 $30\~35\;Gy$에서 7명 중 1명, $35\~40\;Gy$에서 16명중 1명이었고 40 Gy 이상에서는 재발이 없었다. 방사선 조사영역 내 재발에 유의한 예후인자는 없었으나 5 cm 이상인 종양에서 재발하였고 5 cm 미만인 종양은 30 Gy에서도 재발하지 않았다. 10 년 방사선 조사영역내 무재발 생존율, 무병생존율, 전체생존율은 각각 $96\%,\;76\%,\;75\%$였다. 결론 : 국한성 두경부 대세포성 림프종에서 항암화학방사선 병용요법 시 종양의 크기가 5 cm 미만인 경우에는 30Gy의 방사선 조사선량으로도 국소제어를 할 수 있다. 따라서 방사선치료에 따르는 구강건조증을 최소화시킬 수 있을 것이다. 5 cm 이상의 종양에서는 30 Gy 이상의 방사선 조사 선량이 필요하리라 생각된다.

  • Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year-old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.
