Objective: Pegfilgrastim is recently introduced that is long acting G-CSF for prophylaxis of febrile neutropenia. Treatment of non-Hodgikin's lymphoma (NHL) with R-CHOP is classified with relative high risk of febrile neutropenia. The study evaluated the prophylactic effect of pegfilgrastim to reduce the incidence of febrile neutropenia associated with R-CHOP of patient in NHL. And the risk factors associated with the incidence of FN and related events were evaluated. Methods: This retrospective study reviews the Electronic Medical Record of 68 NHL patients who received R-CHOP chemotherapy in single center between September 2013 and August 2014. These patients were classified who receive prophylaxis pegfilgrastim or no prophylaxis. Results: Sixty eight patients received R-CHOP with NHL. In 144 cycles of patients receiving pegfilgrastim, compared with no prophylaxis 178 cycles, had a lower incidence of febrile neutropenia (5.5% vs. 23.6%, p = 0.001), grade 3 or grade 4 neutropenia (14.4% vs. 89.8%, p < 0.001) and neutropenia related events (p < 0.05). The risk of febrile neutropenia after prophylaxis was significantly associated with age ${\geq}65$ (OR: 5.87, 95% CI 1.07-32.27, p = 0.042), $IPI{\geq}3$ (OR: 7.2, 95% CI 1.31-39.6, p = 0.023), S.alb < 3.5 g/dL (OR: 31.01, 95% CI 6.32-152.17, p < 0.0001). In multiple logistic regression analysis, lower baseline serum albumin (OR: 21.1, 95% CI 3.8-116.98, p = 0.001) was significantly associated with occurrence of febrile neutropenia. Conclusion: The study recommends prophylactic pegfilgrastim through risk assessment of febrile neutropenia in patients with non-Hodgikin's lymphoma receiving R-CHOP.

Twenty patients with biopsy-proven Waldeyer's ring lymphoma were treated with radiotherpy between 1984 and 1990 at the Department of Radiation Therapy, Inje University Paik Hospital and seventeen evaluable patients were analysed retrospectively. Dose of radiation ranged from 35 to 50 Gy to Waldeyer's ring structure with an additional 5 and 10 Gy boost dose to the primary site. The lower cervical nodes received 35 to 60 Gy. The median follow-up period was 24 months (range;9 to 80 months). The 5-year overall survival rate was $50.2{\%}$ and 5-year disease free survival rate was $47.1{\%}$. The final local control rate was $82.4{\%}$. The relapse developed average 10 months after treatment. Most of relapses were systemic ($87.5{\%}$). The patients with stage I disease fared better than advance stage. The favorable histology of lymphoma showed better prognosis than unfavorable histology. There was no significant difference in survival rate between radiotherapy alone and combination of chemotherapy and radiotherapy in early stage lymphomas. But of the patients with advanced stage, those who received chemotherapy and radiotherapy had better prognosis than those treated with radiotherapy alone.

A 66-year-old male patient was admitted due to chest pain and dyspnea of 1 year duration, He had history of treatment for tuberculosis and pleurisy, about 40 years ago. At another hospital the patient underwnt closed thoracostomy drainage for six months, and thereafter the symptom gradually aggrevated. Under the diagnosis of chronic tuberculous empyema, decortication was performed. The peel attached to the posterolateral aspect of chest wall, there was an area of soft tissues with pale-brown discoloration, extending to intercostal muscles, but sparing overlying muscles. The biopsy specimen of the lesion was pathologically diagnosed as diffuse, large T-cell non-Hodgkin`s lymphoma. A review of the literature showed that malignant lymphoma of this type have been reported exclusively from Japan but never from other countries including Korea. After 1 year of followup period, the patient is well and stable.

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.

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.

Background: The objective of this study was to investigate the MSCT characteristics of PTL in order to enhance the awareness of this uncommon entity among both clinicians and radiologists. Materials and Methods: The clinicopathological data and MSCT images of 27 patients with PTL were retrospectively reviewed. The MSCT appearances were classified into three types: type 1, solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, enlarged thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: The patients were enrolled in the study with a mean age of 68 years (range, 51-86years) and compression symptoms or enlarged cervical lymph nodes at diagnosis. Hashimoto's thyroiditis was in 20 patients. All patients had non-Hodgkin lymphoma of B-cell in origin, including 22 cases of diffuse large B-cell lymphoma (DLBCL) and 5 of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT). For MSCT appearance, type 1 pattern was observed in 2 patients, type 2 in 8, and seventeen type 3 in 17. The lesions occurred in more than one lobe with a mean maximal transverse diameter of 6.9 cm and an ill-defined margin. Most tumors showed a homogeneous attenuation equal to that of surrounding muscles before contrast and obvious enhancement after contrast. Cervical lymph node involvement and invasion of the trahea and (or) esophagus were mainly observed in patients with DLBCL. Conclusions: PTL should be clinically considered in elder patients presenting with a history of Hashimoto's thyroiditis and cervical lymphadenopathy. The MSCT characteristics of PTL includes a mass diffusely affecting more than one thyroid lobe, isointense to muscle and obvious enhancement before and after contrast. DLBCL, the most common histological subtype of PTL, is associated with a higher invasive tendency.

Objective: To evaluate stromal cells of the bone marrow microenvironment (BMM) in bone marrow trephine biopsy (BMTB) specimens, with a focus on fibronectin, tumor necrosis factor- alpha (TNF-${\alpha}$) and L-selectin in Non-Hodgkin's lymphoma (NHL) patients, before and after therapy. Materials and Methods: A total of 80 de novo NHL patients, 64 with B-cell lymphomas 80%, (follicular cell lymphoma (FCL) in 32, chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in 12, and diffuse large cell lymphoma in 20) and 16 with T-cell lymphomas (20%) all diagnosed as T-Lymphoblastic lymphomas, were evaluated before and after therapy. For comparison, 25 age and sex matched BM donors, were included as a control group. BMTB material and BM aspirates were taken for morphological assessment of stromal cells, the plasma of these samples being examined for $TNF{\alpha}$ and L-selectin by ELISA, and fibronectin by radial immunodiffusion (RID). Results: BM stromal cells comprising reticular macrophages and fibroblasts were elevated in 53.3% of NHL cases at diagnosis, while BM fibronectin levels were decreased and BM $TNF{\alpha}$ and L-selectin were higher than in controls (p<0.05). In NHL cases, elevated values of BM $TNF{\alpha}$ and BM L-selectin were associated with signs of aggressive disease, including >1 extra nodal sites, detectable B symptoms, high grade, BM and CNS invasion, and a high International prognostic index (IPI) (p<0.05). Conclusion: BMM components, $TNF{\alpha}$, L-selectin and fibronectin, in NHL can be useful in evaluating disease activity, extent and response to treatment and as prognostic markers according to the IPI.

Purpose: We retrospectively reviewed the results of radiotherapy for localized ocular adnexal MALT lymphoma (OAML) to investigate the risk factors of cataract. Methods: Sixty-seven patients with stage IE OAML treated with radiotherapy at Seoul St. Mary's Hospital from 2001 to 2016 were included. Median treatment dose was 30 Gy. Lens protection was done in 52 (76%) patients. Radiation therapy (RT) extent was as follows: superficial (82.1%), tumor mass (4.5%), and entire orbital socket (13.4%). The risk factors for symptomatic cataract were analyzed using the Cox proportional hazard model. Results: Median follow-up time was 50.9 months (range, 1.9 to 149.4 months). All patients were alive at the time of analysis. There were 7 recurrences and there was no local recurrence. Median time to recurrence was 40.4 months. There were 14 cases of symptomatic cataract. Dose >30 Gy had hazard ratio of 3.47 for cataract (p = 0.026). Omitting lens protection showed hazard ratio of 4.10 (p = 0.008). Conclusions: RT achieves excellent local control of ocular MALT lymphoma. Consideration of RT-related factors such as lens protection and radiation dose at the stage of RT planning may reduce the risk of RT-induced cataract after radiotherapy.

Purpose: We performed this study retrospectively to evaluate local control, survival, prognostic factors, and failure patterns in patients with non-Hodgkin's lymphoma of Waldeyer's ring. Materials and Methods: From April 1984 to November 1996,41 patients with non-Hodgkin's lymphoma of Waldeyer's ring were treated with combined chemotherapy and radiation therapy. Age was ranged from 19 to 73 years old with a median age of 55 years, and there were 26 male and 15 female patients. Primary site was tonsil in 26 and base of the tongue in 7 and nasopharynx in 8, and stage distribution showed stage I in 12 and stage II in 29 patients. Pathologic classification was done according to Working Formulation. There were 1 with follicular mixed small cleaved and large cell, 8 with diffuse small cleaved cell, 7 with diffuse mixed small and large cell, and 25 cases with diffuse large cell. All patients were treated with combination of chemotherapy and radiation therapy. Chemotherapy regimen consisted of either CHOP-Bleo(cyclophosphamide, adriamycin, vincristine, prednisolone, bleomycin) or COP-BLAM III(cyclophosphamide, vincristine, prednisolone, bleomycin, adriamycin, procarbazine). Radiation dose ranged from 3600cGy to 6620cGy with a median dose of 5040cGy. Follow-up time was ranged from 15 months to 159 months(median 55 months). Results: The complete response was achieved in 98%(40/41) and partial response in 2%(1/41). The complete response rate were the followings: 66.7% for stage I and 51.7% for stage II after chemotherapy, 100% for stage I and 96.6% for stage II after overall treatment respectively. The overall survival rate and disease-tree survival rates at 5 years were 82.6% and 79.5%, respectively. Prognostic factors for overall survival were age(p=0.007), stage(p=0.03), nodal status(p=0.006) and radiation dose(p=0.003). The factors associated with disease-tree survival were stage(p=0.04), nodal status(p=0.004) and radiation dose(p=0.009). The failure patterns were analized in evaluable 35 patients with complete response. Locoregional failure was noted in 2 patients and distant metastasis in 5 patients. Conclusion: Our results suggest that combined modality therapy is the appropriate treatment for stage I-II intermediate grade non-hodgkin's lymphoma of the Waldeyer's ring. However, our material is small and the analysis is retrospective. Randomized prospective studies for combined therapy, radiation therapy alone and chemotherapy alone are needed.

Primary cardiac lymphoma is an extranodal malignant lymphoma of any cell type involving only heart and pericardium without dissemination. Patients usually present symptoms of heart failure, arrhythmias, pericardial effusion and cardiac tamponade. Diagnosis of primary cardiac lymphoma can be performed by echocardiogram, CT and MRI and cytologic examination of pericardial effusion or transvenously biopsied cardiac tissue. Prognosis of primary cardiac lymphoma is poor. Because of poor prognosis, early diagnosis and complete surgical excision is essential and postoperative systemic chemotherapy or radiotherapy is useful. In this case extensive tumor infiltration on the right ventricle and atrioventricular groove preclude surgical excision. Tissue biopsy revealed primary cardiac lymphoma. After postoperative chemotherapy and radiotherapy, the size of intracardiac mass is decreased in follow up chest CT scan and echocardiogram and symptoms of patient are relieved. Therefore, we report a case of primary cardiac lymphoma with review of literatures.
