Neurolymphomatosis, an uncommon manifestation of non-Hodgkin's lymphoma, is lymphomatous infiltration of peripheral nerves. We confirmed the diagnosis of neurolymphomatosis in a 75-year old woman with a history of complete remission of diffuse large B cell type lymphoma on the nasal cavity seven years ago. She complained of painful weakness of left leg and took the electrophysiologic study, extremity ultrasonography, fluorodeoxyglucose PET-CT, and extremity MRI serially. She was diagnosed as neurolymphomatosis by targeted posterior tibial nerve mass biopsy.

Purpose: Follicular lymphoma (FL) is an indolent non-Hodgkin's lymphoma that is highly sensitive to radiotherapy (RT). However, the effectiveness of RT has not been well established. We reviewed our experiences to assess the role of RT for FL and analyze treatment results. Materials and Methods: Retrospective analysis was done on 29 patients who received first RT between January 2003 and August 2013. Of 23 early stage (stage I, II) patients, 16 received RT alone, four received chemotherapy followed by RT, two received RT postoperatively, and one received salvage RT for relapse after resection. Six advanced-stage (stage III, IV) patients received RT after chemotherapy: two received consolidation RT, three received salvage RT for residual lesions, and one received RT for progressive sites. Median RT dose was 30.6 Gy (range, 21.6 to 48.6 Gy). Median follow-up duration was 62 months (range, 6 to 141 months). Results: All patients showed complete response in the radiation field. Eight outfield relapses were reported. Seven patients received salvage treatment (three chemotherapy, four RT). Four patients showed excellent responses, especially to RT. Estimated 5-year and 10-year relapse-free survivals were 72% and 60%. In the RT-alone group, 5-year relapse-free survival was 74.5%. All advanced-stage patients were disease-free with 100% 5-year overall survival. Disease-specific death was noted in only one patient; four others died of other unrelated causes. No significant toxicity was reported. Conclusion: RT resulted in excellent treatment outcomes for all FL stages when used as a primary treatment modality for early stage or salvage-treatment modality for advanced-stage disease.

Bigihwan which has been widely used in Oh-jug in oriental Medicine was investigated on its antitumor effect employing blood cancer cell lines. K 562 derived from human erytholeukemia, Raji from lymphoma and $MO_4$ from hlastogenic cancer were used in this study to see the analytical evaluation of Bigihwan' s antitumor effect using three different kinds of methods such as $^{3}H-thymidine$ up take assay. MTT assay and live cell counts by Trypan blue assay. The result obtained are as follows. 1. When higher than 10% Bigihwan was treated. inhibitory effect of tumor killing action was observed showing the increasing order of $MO_4$, K 562 and Raji(Fig. 3). 2. When 1 to 5% of Bigi-hwan was treated, 4 to 30% of tumor cell survival was observed according to various blood tumor cell lines suggesting that antitumor effect of Bigi-hwan was different as the characteristics of tumor cells showing 70 to 95% cell killing effent(Fig. 4). 3. Compared the survivals of cells by relative scales though the initial cpm was variable because of different cell growth rate. Raji was most effective being killed 95% by the treatment of 1% Bigihwan while Raji and K562 showed 93% by 5% Bigihwan.(Fig. 5) 4. The survival rate of Raji derived from Burkitt lymphoma was rather increased to 2.3 times when Bigihwan concentration was increased from 1 to 10% lmplying of refraining from over use of this anticancer drug. specially to lymphoma patients(Fig. 5). 5. Bigihwan was most effective to K 562 and then $MO_4$ showing 95% tumor cell death by using 1% of this anticancer drug while it was least effective to Raji showing only 68% of tumor cell death(Fig.7). 6. Judging from the all the analytical methods used in this study, through all different three tumor cell lines. Bigihwan was most effective to K 562 derived from human erythroleukemia.

Anaplastic large cell lymphoma(ALCL) is a recently recognized large cell lymphoma characterized by large pleomorphic cells, with prominent nucleoli, expressing the CD30(Ki-1) antigen. It is often misdiagnosed as metastatic carcinoma, malignant histiocytosis or Hodgkin's disease. Primary pulmonary ALCL is extremely rare although it frequently involves extranodal sites, e.g. skin, bone, gastrointestinal tract, soft tissue and lung. We report a case of ALCL suspected as primarily involving lung.

Malignant T cell lymphoma is a morphologically and immunologically distinct subtype of non-Hodgkin's lymphoma. One of the most striking clinical findings is relatively high incidence in males in their twenties or thirties with cervical, supraclavicular and axillary lymphadenopathy (50%), mediastinal mass (50%) or less commonly with extranodal disease. More than 90% of patients present with stage III or IV disease and approximately 60% of patients develop bone marrow infiltration. Clinical trials are needed to optimize therapeutic strategies, since these tumors have a poor prognosis and need to be treated aggressively. A 17-year-old male was admitted to the hospital because of chest pain. Chest PA and CT scan revealed massive pleural effusion and soft tissue masses with destructive change of right third and eighth ribs Histologic diagnosis of pleura and chest wall mass revealed high grade, pleomorphic T cell type, malignant lymphoma.

Objective : Primary central nervous system lymphoma[PCNSL] is a non-Hodgkin's lymphoma arising in the central nervous system. Combined chemotherapy and radiation therapy is the standard treatment for PCNSL. However, treatment induced neurotoxicity is a major problem especially in elderly patients. Methods : From May 2001 to April 2004, elderly five patients with PCNSL confirmed via pathological examination were underwent Novalis radiosurgery in authors' institution, who were investigated retrospectively. Of these patients, 2 were male and 3 were female, with a mean age 68 years old [range $65{\sim}73$]. The number of lesions was 1 in 2 patients, 2 in 2, and 3 in 1. The mean follow up period was 12.6 months [range $8{\sim}16$]. Results : Clinical symptoms and signs in all patients markedly improved within 1 weeks after Novalis radiosurgery. The Karnofsky performance status score was also improved from a pre-radiosurgery average of 68 to a post-radiosurgery one of 82. All of treated lesions showed a partial or complete regression of the original mass. There have been no complication following Novalis radiosurgery. Conclusion : The preliminary results of our experience indicate that radiosurgery with Novalis provides a safe and effective therapeutic alternative treatment of PCNSL in elderly patients.

A 3-year-old spayed female Russian blue cat was presented for dyspnea, nasal discharge, and stertorous breathing. Plain thoracic radiography revealed no specific findings. Computed tomography (CT) was performed to differentiate upper airway tract disorders. It revealed the presence of an iso-attenuating mass measuring 10.0 × 7.9 × 15.6 mm, with mild homogeneous contrast enhancement occupying the rostral nasopharynx. The mass was surgically debulked via a longitudinal incision in the soft palate. Histopathological and immunohistochemistry analysis of the surgically excised mass revealed CD3-/CD79a+ B cell lymphoma with an incomplete margin. The patient underwent hypofractionated radiation therapy, receiving a total of 36 Gray (Gy) in 6 Gy fractions over a six-week period. A follow-up CT examination was performed after 27 months of irradiation and the patient was confirmed to have achieved a complete response. There were no complications related to irradiation. The patient was alive for 40 months without recurrence. This study suggests that hypofractionated radiation therapy combined with surgical debulking could be considered as a treatment option for feline nasopharyngeal lymphoma.

Background: The incidence of various types of cancers including the non-Hodgkin's lymphoma (NHL) has increased during the recent years. Diet and lifestyle factors have been reported to play an important role in the etiology of NHL. However, no such data are available from the Middle Eastern countries, including Oman. Materials and Methods: Forty-three histologically confirmed cases of non-Hodgkin's lymphoma (NHL) diagnosed at the Sultan Qaboos University Hospital (SQUH) and the Royal Hospital (RH), Muscat, Oman and forty-three age and gender matched controls were the subjects of this study. Frequency matching was used to select the control population. Information on social and demographic data as well as the dietary intake was collected by personal interviews, using a 117-items semi-quantitative food frequency questionnaire. Results: A non-significant increased risk of NHL was observed with higher body mass index (BMI) (OR=1.20, 95%CI: 0.45, 2.93), whereas a significantly decreased risk of NHL was associated with a higher educational level (OR=0.12, 95%CI: 0.03, 0.53). A significantly increased risk was observed for higher intake of energy (OR=2.67, 95%CI: 0.94, 7.57), protein (OR=1.49, 95%CI: 0.54, 4.10) and carbohydrates (OR=5.32, 95%CI: 1.78, 15.86). Higher consumption of daily servings from cereals (OR=3.25, 95%CI: 0.87, 12.09) and meat groups (OR=1.55, 95%CI: 0.58, 4.15) were also found to be associated with risk of NHL, whereas a significantly reduced risk was associated with higher consumption of vegetables (OR=0.24, 95%CI: 0.07, 0.82). The consumption of fruits, milk and dairy products however showed no significant association with the risk of developing NHL. Conclusion: The results suggest that obesity, high caloric intake, higher consumption of carbohydrate and protein are associated with increased risk of NHL, whereas a significantly reduced risk was observed with higher intake of vegetables.

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.
