  • Purpose: Primary malignant lymphomas of the salivary glands are uncommon, representing only 1.7% to 3.1% of all salivary neoplasms and 0.6% to 5% of all tumors and tumor-like lesions of the parotid gland. Lymphomas of the parotid glands are usually manifestations of a systemic disease process but primary lymphomas of the parotid glands are rare. Most of these lesions are classified as extranodal non-Hodgkin's lymphoma. We report the clinicopathological features of primary malignant lymphoma of the parotid gland based on an analysis of our cases. Methods: The subject was a 48-year-old male patient with a malignant lymphoma originating in the parotid gland, which had been slowly increasing in size over previous 6 months. The diagnosis was established by MRI and a superficial lobectomy. After diagnosis, the patient was referred to an oncologist for staging and medical treatment. Results: The stage was IIIA. The patient was treated with chemotherapy following surgery with rituximab and CHOP (Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). The tumor was controlled successfully by chemotherapy. The patient was followed up for 1 year with no relapse. Conclusion: A case of primary non-Hodgkin's lymphoma of the parotid gland was treated with a superficial parotidectomy and chemotherapy. The disease was well controlled after a 1 year follow-up.

  • Background: Non-Hodgkin's lymphoma (NHL) is a heterogeneous type of neoplasm of the lymphatic system. To have a more accurate and early diagnosis we need to know signs, symptoms and complications of lymphoma in early stages besides pathology and immunohistochemistry. Materials and Methods: This prospective study included 110 cases of NHL that were followed since February 2012 till November 2013. Biopsies were taken from all the patients besides bone marrow study. Signs and symptoms were categorized into "B" symptoms, general, lymphadenopathy and extranodal involvement and we compared the frequencies by stage and grade. Results: Of 110 cases, 88.9% had B-cell and 11.1% T-cell type with mean age $48.5{\pm}18.6$ years. "B" symptoms and lymphadenopathy were more common in men. Cervical lymphadenopathy was the most common sign (44.8%). and hematologic, bone marrow, bone and neurologic lesions were the most common complications. All complications were more common in males. "B" symptoms were seen mostly in stage III, general signs and symptoms in stage IV, and lymphadenopathy in stage II. Intermediate grade was also the most common in all signs and symptoms. In this study 12 (10.9%) patients had relapse, with neurologic and bone marrow as the most common sites of tumor recurrence. Conclusions: There is a meaningful relationship between male gender for NHL and anemia that can be due in part to higher incidence of bone marrow involvement and stage IV disease in male cases. We also found a strong relationship between low grade NHL and age. On the other hand extranodal involvement is more common in female groups.

  • Background: Non-Hodgkin lymphoma (NHL) is a solid tumour of lymphocytes, important elements in the immune system. According to 2006 data, in Turkey the incidence was 6.5 per 100,000 in males, and 4.4 in females. The relationship between the use of pesticides and development of NHL has been extensively investigated in many studies, and it has been demonstrated that the risk of NHL is increased by exposure to such compounds. Antalya is a region of intensive agricultural activity. In this study, the relationship between the incidence of lymphoma in Antalya and the amount of pesticides employed was investigated. Materials and Methods: The study used data from 1995 to 2010 on the patients from the databank of TR Ministry of Health, Antalya Provincial Health Directorate, Cancer Registration Center and the patients who were histopathologically diagnosed with NHL during these years. Results: The relationship between the amount of pesticide used and the incidence was studied with the Spearman correlation analysis and the p value was found as 0.05. The correlation coefficient was 0.497. An increase in the NHL incidence over the years was identified, with a 2.42-fold increment found from 1995 to 2005 and a 2.77 fold elevation from 1995 to 2010. The use of pesticides increased 1.89 fold over the same period. Conclusions: Our study investigated the relationship of the pesticides used with NHL patients diagnosed during the same year. Since the time elapsing after exposure to pesticides until the development of cancer is not clear, no comparison can be made at present. We believe that the increase in use of pesticides since 1995 may be associated with the increase in the incidence of NHLand therefore that further studies on the issue including measurements of serum pesticide levels, are required.

  • The uterine cervix is an uncommon site of primary non-Hodgkin's lymphoma (NHL). Although the cytologic findings of NHLs are well known, most cervicovaginal smear of uterine NHLs give lower diagnostic yield than common epithelial malignancy because abnormal cells do not appear in the sample in the absence of surface ulceration. Herein, we describe cytologic findings of a case of uterine cervical NHL which was initially diagnosed by cervicovaginal smear. The tumor cells were relatively uniform, isolated, large-sized with scanty cytoplasm and round or indented nuclei. The nuclei had stippled chromatin and small nucleoli. Histologically and immunohistochemically the tumor was proven to be large cell lymphoma of T-cell lineage.

  • Interleukin-10 (IL10) plays an important role in initiating and maintaining an appropriate immune response to non-Hodgkin lymphoma (NHL). Previous studies have revealed that the transcription of IL10 mRNA and its protein expression may be infl uenced by several single-nucleotide polymorphisms in the promoter and intron regions, including rs1800896, rs1800871, and rs1800872. However, the impact of polymorphisms of the IL10 gene on NHL prognosis has not been fully elucidated. Here, we investigated the association between IL10 polymorphisms and NHL prognosis. This study involved 112 NHL patients treated at the National Cancer Center, Korea. The median age was 57 years, and 70 patients (62.5%) were men. Clinical characteristics, including age, performance status, stage, and extra-nodal involvement, as well as cell lineage and International Prognostic Index (IPI), were evaluated. A total of four polymorphisms in IL10 with heterozygous alleles were analyzed for hazard ratios of overall survival (OS) and progression-free survival (PFS) using Cox proportional hazards regression analysis. Diffuse large B-cell lymphoma was the most common histologic type (n = 83), followed by T-cell lymphoma (n = 18), mantle cell lymphoma (n = 6), and others (n = 5). Cell lineage, IPI, and extra-nodal involvement were predictors of prognosis. In the additive genetic model results for each IL10 polymorphism, the rs1800871 and rs1800872 polymorphisms represented a marginal association with OS (p = 0.09 and p = 0.06) and PFS (p = 0.05 and p = 0.08) in B-cell lymphoma patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). These findings suggest that IL10 polymorphisms might be prognostic indicators for patients with B-cell NHL treated with R-CHOP.

  • Non-Hodgkin's lymphoma arising in lung comprises 0.5% of primary lung tumor and 3% of extranodal lymphoma. The most common radiographic abnormalities of pulmonary lymphoma include pulmonary nodule and consolidation, but hilar lymphadenopathy is rarely observed Recently we experienced primary pulmonary T-cell lymphoma presenting with bilateral hilar lymphadenopathies and diffuse pulmonary infiltration A 39-year-old man was admitted to the hospital because of fever, cough, and severe dyspnea. Chest PA obtained on admission revealed bilateral hilar lymphadenopathies and diffuse bilateral pulmonary infiltration. The diagnosis of sarcoidosis was strongly suggested and empirical treatment with corticosteroids resulted in dramatic clinical and radiological improvement for a short time. Eventually, CT-guided lung biopsy was performed and the specimen disclosed primary pulmonary Non-Hodgkin's lymphoma of T-cell origin, diffuse small lymphocytic with focal plasmacytoid differentiation.

  • 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.

  • 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.

  • Background: A combination of rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is one of the most effective front-line therapies to treat B-cell non-Hodgkin's lymphoma (NHL). The aim of this trial was to evaluate overall survival (OS), progression free survival (PFS) and toxicity of R-CHOP-14 compared to R-CHOP-21 in untreated stage III and IV B-cell NHL patients with Iranian ethnicity. Materials and Methods: In phase III trial, patients with previously untreated stage III and IV indolent and aggressive B-cell NHL were randomly assigned by using a minimization method to receive six to eight cycles of either R-CHOP-21 (administered every 21 days) or R-CHOP-14 (administered every 14 days with granulocyte colony-stimulating factor). Results: A total of 143 patients were randomly enrolled in our study (66 patients in R-CHOP-14 group and 77 patients in R-CHOP-21), between 2011 and 2014. The mean follow-up was 45 months at the time of treatment analysis. The 2-year and 5-year PFS rates for the R-CHOP-14 group were 83.6% vs 73.6% and for R-CHOP-21 group were 75% vs 54%. The 2-year and 5-year OS rates for R-CHOP-14 group were 98% vs 89% and for R-CHOP-21 group were 84.4% vs 67.5%. There was a significant correlation for PFS and OS in the two arms. There was no significant difference between adverse events with the two regimens. Conclusions: In our research improved survival was found with CHOP-14 as compared to CHOP-21. It is possible that drug metabolism in different races/ethnicities may be one important factor.
