Nephrotic syndrome is a relatively rare complication of malignancy. A few cases of nephrotic syndrome accompanying Hodgkin's disease, non-Hodgkin lymphoma, leukemia and other malignancies have been reported since the first case of the nephrotic syndrome associated with extrarenal malignancy was reported in 1922. Hodgkin's disease and solid tumors are known to be the most common malignancies accompanying nephrotic syndrome. The pathologic findings of kidney in patients with Hodgkin's disease commonly show minimal change nephropathy. Membranous glomerulonephropathy is the most common pathologic feature in patients with solid tumors. Although membranous glomerulonephropathy related to small cell lung cancer has rarely been reported in Korea, minimal change nephropathy accompanying small cell lung cancer has never been reported. We present here a case of a 70 year-old male with minimal change nephropathy that was related to small cell lung cancer. We detected small cell lung cancer during the diagnosis work-up of nephrotic syndrome. We suggest that nephrotic syndrome can be a manifestation of underlying malignancy.

Radiotherapy result of 162 patients with stage I, II intermediate grade non-Hodgkin's Iymphoma was analyzed to clarify the role and limit of radiotherapy. Of 68 initial failures, 38.2% occurred in field and 61.8% occurred out of field. Proportion of in-field and out-of-field failures in stage I was 30.0% and 70.0%, respectively with involved field treatment and was 43.8% and 56.2% with extended field treatment, respectively; in stage ll , was 16.7% and 83.3%, 41.7% and 58.3%, respectively. The disease free suwival rate at S years was 48.1% for all patients and was 50.3% and 40.4% for patients with stage I and II, respectively. The survival was significantly different by stage. Bulky tumors (${\geq}10$ cm) and B symptoms didn't influence prognosis significantly. The 5 year disease free suwival with extended or wide field was better than that with involved field especially in stage I. Overall survival rates for all patients, patients with stage 1, and ll disease were 57.7%, 65.3% and 52.2% , respectively, after survival gain of the salvage chemotherapy was combined. But the overall survival of stage I disease was not better than that of stage II disease. Thus, extended field was required to achieve better disease free survival and relapsed cases might gain with chemotherapy.

From April 1985 to September 1989, 26 patients with stage I and II non-Hodgkin's lymphoma of unfavorable histology localized in head and neck region were treated with combined modality (combination chemotherapy plus radiotherapy) at the Department of Therapeutic Radiology in Kyungpook National University Hospital. Of the 26 patients, 23 showed complete response and 3 partial response. Between these two groups there were no statistical differences according to the variables. Three-year survival and disease-free survival rate were $62.4{\%}$ and $65.2{\%}$, respectively. Unilateral involvement of neck node (p<0.05), radiation dose over 5000 cGy (p<0.01), and 6 or more cycles chemotherapy (p=0.06) had a favorable effect on 3-year survival rate. There were 8 recurrences including 3 partial responders, 1 local failure, 1 distant failure, 1 contiguous failure, and 2 simultaneous local and distant failure. It could be suggested that combined modality treatment might be necessary for the treatment of stage I and II Non-Hodgkin's lymphoma of unfavorable histology.

Primary non-Hodgkin lymphoma (NHL) of the breast is a very rare disease, and the mammographic and ultrasonographic findings of breast lymphoma are variable. There are several reports of magnetic resonance (MR) imaging findings in patients with breast lymphomas; however, few reports have described the findings observed on MR spectroscopy or the features of diffusion weighted (DW) imaging. The authors report the findings of classical MR imaging, MR spectroscopy and DW imaging of a 48-year-old woman and a 40-year-old woman with primary non-Hodgkin's lymphoma of breasts. Mammography and breast ultrasonography revealed a mass with circumscribed margin. The mass showed strong enhancement after contrast injection on MR imaging. DW imaging showed reduced diffusion and high-amplitude choline (Cho) peak at 3.22 ppm was detected by single voxel MR spectroscopy which was consistent with malignancy.

The increasing risk of subsequent malignancy after treatment of malignant lymphoma is well known, which is mainly due to longer survival of these patients. Radiotherapy at an early stage of Hodgkin's disease or non-Hodgkin's lymphoma is accepted to be associated with future occurrence of secondary thyroid cancer. Nevertheless, the synchronous presentation of these malignancies is extremely rare. Well differentiated thyroid cancer, a slow-growing tumor that responds to therapy with surgery and radioactive iodine, is associated with prolonged survival. therefore, it is important to make this diagnosis in patients who show evidence of malignant lymphoma. Furthermore, appropriate treatment must be considered for thyroid cancer to improve the prognosis of these patients. We herein reported 4 cases of synchronous thyroid cancer and malignant lymphoma in patients who had not previously recieved radiotherapy or chemotherapy.

A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin's lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients (43/69, $62.3{\%}$) were Stage I and 26 patients (26/69, $37.7{\%}$) were Stage II, and B symptom was found in $10.1{\%}$ (7/69). Nodal lymphoma was $21.7{\%}$ (15/69); 14 patients with supradiaphragmatic disease and 1 patient with infradiaphragmatic disease. Extranodal lymphoma was $78.3{\%}$ (54/69): $64.8{\%}$ (35/54) for head and neck, $25.9{\%}$ (14/54) for gastrointestinal tract. Histologically, low grade consists of $8.7{\%}$ (6/69), intermediate grade $84.2{\%}$ (56/69), high grade $10.1{\%}$ (7/69), and diffuse large cell type was the most frequent form with 36 patients (36/69, $52.2{\%}$). Eighteen patients ($26.1{\%}$) were treated with radiation therapy alone,20 patients ($29.0{\%}$) with radiation therapy combined with chemotherapy, 15 patients ($21.7{\%}$) with radiation therapy combined with surgery and chemotherapy, Median survival duration was 28 months, and the range of survival time was from 1 month to 134 months. Overall five-year survival rate for Stage I and II disease was $54.2{\%}$, with $64.5{\%}$ for Stage I and $37.1{\%}$ for Stage II. For nodal lymphoma,5-year survival rate was $45.9{\%}$, and $56.5{\%}$ for extranodal lymphoma; $60.6{\%}$ for head and neck, $52.9{\%}$ for GI tract primary disease. Local control rate for all patients was $88.4{\%}$ (61/69), with $80{\%}$ (12/15) for nodal lymphoma and $90.7{\%}$ (49/54) for extranodal lymphoma. The total failure rate was $34.8{\%}$ (24/69). Five of 24 ($20.8{\%}$) patients who were failed developed local failure only, $12.5{\%}$ (3/24) local failure with distant failure, and distant failure only were found in $66.7{\%}$ (16/24). Between nodal lymphoma and extranodal lymphoma, there was no significant survival difference, but extranodal lymphoma showed higher incidence.

From 1982 to 1991, sixteen Patients with primary non-Hodgkin's lymphoma of the central nervous system(CNS) were seen at Kyung Hee University Hospital. The most common subtypes were large, noncleaved cell lymphoma and immunoblastic lymphoma of B cells. Lesions most commonly involved were the parietal lobes and/or deep nuclei. Positive cerebrospinal fluid cytology was rare at initial presentation. Sixteen patients were treated with surgical biopsy or resection followed by whole brain radiotherapy at a median dose of 40 Gy(range=30-50 Gy) with variable boost doses. Of 16 patients who underwent surgery and postoperative radiotherapy, fourteen patients died between 2 and 49 months following treatment, and two are alive with no evidence of disease at 8 and 22 months. The 1-and 2-year survival rates were 55.6$ \% $ and 34.7$ \% $, respectively with 12 months of median survival. Patterns of failure were analyzed in eleven patients of total 16 patients. Failure at the original site of involvement was uncommon after radiotherapy treatment. In contrast, failure in the brain at sites other than those originally invovled was common in spite of the use of whole brain irradiation. Failure occurred in the brain 11/16(68.7$ \% $), in spinal axis 4/16(25.0$ \% $). The age, sex, location of involvement within CNS, numbers of lesion, or radiation dose did not influence on survival. The authors conclude that Primary CNS lymphoma is a locally aggressive disease that is poorly controlled with conventional radiation therapy. The limitation of current therapy for this disease are discussed, and certain promising modality should be made in regarding the management of future patients with this disease.

Constrictive bronchiolitis, one of small airway diseases, is very rare and occupies one of the two arms of bronchiolitis obliterans together with proliferative bronchiolitis. Proliferative bronchiolitis, presenting the prototype with bronchiolitis obliterans with organizing pneumonia(BOOP), can be easily taken into diagnostic consideration in terms of relatively rapid clinical course and radiologic presentation as if atypical pneumonia with interstitial and alveolar infiltrations. Meanwhile constrictive bronchiolitis is not only very Tare but also easily overlooked as chronic obstructive pulmonary diseases such as emphysema, because it usually shows normal chest radiographic finding and obstructive pattern in pulmonary function test. In the aspects of the response to treatment, proliferative bronchiolitis showed dramatic response to the corticosteroid while constrictive bronchiolitis is intractable, which is easily explained on the basis of the pathologic characteristics of cicartrical replacement of bronchiolar walls. The bronchiolitis, both proliferative and constrictive, can be associated with diverse conditions such as inhalational injury, postinfectious process, drug of chemical induced reactions, connective tissue diseases, and organ trasplantation. And there is idiopathic type which has no associated condition. There is one explanation that both types of bronchiolitis lie on the same disease spectrum because the different disease pattern can be evoked from the same etiology. In contrast, another explanation is suggested that both types of bronchiolitis are one of nonspecific tissue reaction rather than a disease specific histologic finding because the various types of causes can provoke the same histologic findings. These dilemma remains for further investigation. With literature investigation, the authors report a case of constrictive bronchiolitis proven by open lung biopsy in 47 year old female who was diagnosed as non-Hodgkin's lymphoma and simultaneously had relatively rapid progression of airflow obstruction and showed negative radiographic finding without the rise factors for the development of chronic obstructive lung disease. We consider it as idiopathic because we could not find any relationship between constrictive bronchiolitis and non-Hodgkin's lymphoma on the literature search and it requires further investigation.

There is paucity of data on non Hodgkin's lymphoma (NHL) from our population in North-East India. In this retrospective study, patients were consecutively followed-up to see the clinic-pathological pattern of NHL, various responses, and pattern of relapses to first line treatment with chemotherapy. All patients in the present study received standard regimen of cyclophosphamde, doxorubicin, vincristine, prednisolone (CHOP) with or without rituximab (R-CHOP) as per our institutional protocol as first line therapy. Our study has shown that, in our adult population, the majority of NHL cases present with stage II and stage III disease and extra nodal involvement, B-cell lymphomas and diffuse large cell lymphomas being the most common subtypes. International prognostic index was a significant factor for varied responses to treatment. The majority of relapses after complete remission occurred in the first year.
