It generally has a poor spontaneous outcome and needs aggressive treatment with systemic and intrathecal chemotherapy. Occurrence at the gastric site is rare. We report the case of a 39-year old woman who presented with a prominent ulcerated lesion of the antrum corresponding histologically to a Burkitt＇s lymphoma associated with He/icobacter py/ori （H pylori） infection. Interphase fluorescence in situ hybridization （FISH） demonstrated c-MYC gene rearrangement in tumour cells without BCL2 or BCL6 gene translocations. Ulcer healing and tumour regression with a complete histological response were obtained 8 wk after Hpylori eradication. In spite of this complete remission, taking into account the high risk of recurrence, the patient received systemic and intrathecal chemotherapy. Two years later, the patient remained in complete remission. This is the first report of a gastric Burkitt＇s lymphoma responding to Hpylori eradication. These findings raise the question of the potential role of H pylori in the pathogenesis of some gastric Burkitt＇s lymphomas, and show the importance of searching for and eradicating the bacteria in combination with conventional chemotherapy regimens.展开更多

The treatment effect and adverse reactions were evaluated.RESULTS Of the 13 patients, 12 were men and 1 was woman, with a median age of 15 years （range, 11-62）. Three of the patients were in stage Ⅰ, 2 in stage Ⅱ, 2 in stage Ⅲ, and 6 in stage Ⅳ. Advanced cases were 8 （stage Ⅲ and Ⅳ）, accounting for 61.5% of the patients. Bone marrow involvement was found in 2 cases （15.4%） and central nervous system invasion in 4 （30.8%） at the beginning of the treatment. The common involved sites included the superficial lymph nodes （61.5%）, abdominal organs （53.8%）, and abdominal and retro-peritoneal lymph nodes （38.5%）. B symptoms were observed in 7 patients （53.8%）. Serum lactate dehydrogenase （LDH） level was increased in 8 of the 10 patients who underwent the serum LDH determination, while serum uric acid level was increased in 1 of the 10. Pathological diagnosis showed that 11 of the cases were BL and 2 BLL. Of the 13 patients, 11 （84.6%） achieved a complete remission （CR） or CR/unconfirmed （CRu）, and 1 （7.7%） a partial remission （PR）, with a total responsive rate of 92.3%. At a median follow-up of 8 months （range 5-35）, 6 patients were found dead at the end of the follow-up. One of the 13 patients was lost to the follow-up. The 1-year overall survival, progression-free survival and disease-free survival rates were 56.98%, 32.31% and 39.77%, respectively. The grade-Ⅲ or Ⅳ myelosuppression was found in 9 patients during the chemotherapy （69.2%）, and tumor lysis syndrome and grade- Ⅳ total gastrointestinal mucositis were seen in 1.CONCLUSION Intensive short-course chemotherapy is recommended as the optimal first-line treatment for BL and BLL, and actively preventive treatments for chemotherapy-related adverse reactions are essential in the treatment course.展开更多

The differential diagnosis is very difficult,especially when there are small lymphoid cells in Periphcral blood and bone marrow under light microscope. We have observed 34 cases with electron microscope. The studies were correlated with clinical manifestation, cytology, pathology and immunologic histochemistry. Ultrastructural features strongly indicated the difference in three various diseases, although all the immunologic markers showed B-cell type.It is concluded that electron microscopic examination is of a definite significance in the diaguosis and successful treatment.展开更多

Hence the present study examines the BMI-for-age of Indian childhood ALL and NHL survivors. Method: A retrospective study of 118 ALL/NHL survivors and 138 age sex matched was carried out. From the recorded heights and weights were body mass index (BMI) was computed. The survivor data was compared with 138 controls from the data set collected by investigators previously. Results: 82.8% of patients had BMI-for-age in 5th-84th percentile (healthy) at time of diagnosis and at inclusion in the study. Comparison of BMI of survivors with matched controls was not significant. However, The mean BMI-for-age for younger patients (3 to 12 years) was significantly higher than mean BMI-for-age of matched controls. Distribution of data by time elapsed from therapy was significant. Overweight/obesity was observed among the survivors who were off therapy for two years with increase in after four years post-therapy. Conclusion: Our preliminary study indicates late effects of therapy and points to the need of long term assessment of the survivors, even though majority of them were within the normal weight range.展开更多

Methods: This retrospective database study used medical and pharmacy claims (1/2007-7/2012) from a large US health plan. Patients ≥18 years with ≥2 rituximab claims and ≥2 claims for either NHL or CLL were identified. The date of the first rituximab claim were set as the index date, and differences in treatment patterns and health care costs were examined during the period following the index date. Costs were adjusted for patient characteristics using a multivariate regression model. Results: A total of 4441 patients were identified;3167 received rituximab in the office/clinic setting, and 1274 in the hospital outpatient setting. From 2007 to 2012, the percentage of patients receiving rituximab in the hospital outpatient setting increased from 22% to 39%. Patients treated in the hospital outpatient setting vs. the office/clinic setting had fewer average counts of rituximab infusions (5.60 vs. 7.49, p 0.001), higher total health care costs (cost ratio = 1.325, p 0.001), higher infusion day drug and administration costs (cost ratio = 1.509, p 0.001), and higher rates of ER visits and inpatient stays (both p 0.001). Conclusions: These findings suggest that site of care may impact treatment patterns and costs of patients receiving rituximab, and additional research is needed to better understand the reason(s) for these differences by site of service.展开更多

文摘Burkitt＇s lymphoma is a highly aggressive non-Hodgkin lymphoma, often presenting in extra-nodal sites. It generally has a poor spontaneous outcome and needs aggressive treatment with systemic and intrathecal chemotherapy. Occurrence at the gastric site is rare. We report the case of a 39-year old woman who presented with a prominent ulcerated lesion of the antrum corresponding histologically to a Burkitt＇s lymphoma associated with He/icobacter py/ori （H pylori） infection. Interphase fluorescence in situ hybridization （FISH） demonstrated c-MYC gene rearrangement in tumour cells without BCL2 or BCL6 gene translocations. Ulcer healing and tumour regression with a complete histological response were obtained 8 wk after Hpylori eradication. In spite of this complete remission, taking into account the high risk of recurrence, the patient received systemic and intrathecal chemotherapy. Two years later, the patient remained in complete remission. This is the first report of a gastric Burkitt＇s lymphoma responding to Hpylori eradication. These findings raise the question of the potential role of H pylori in the pathogenesis of some gastric Burkitt＇s lymphomas, and show the importance of searching for and eradicating the bacteria in combination with conventional chemotherapy regimens.

文摘Multiple lymphomatous polyposis (MLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL isreviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

文摘Since 1960, the tumor strains of L6565 viral leukemia, SRS lymphoma and L783 transplantable leukemia were established successively in our laboratory. Recently, derived from the strains of threse leukemia/lymphoma, SRS-82 cell line, SACIIB2, SACIIC3 cell clones and a cell line infected with SRS leukemia virus (SRSV/3T3) were obtained at vitro. The main results of study on the biology, virology and Its Induction of differentiation are summarily reported.
文摘Non-Hodgkin’s lymphoma cell leukemia (NHLCL),chronic lymphocytic leukemia (CLL) and hairy cell leukemia (HLC) are the diseases very similar to each other. The differential diagnosis is very difficult,especially when there are small lymphoid cells in Periphcral blood and bone marrow under light microscope. We have observed 34 cases with electron microscope. The studies were correlated with clinical manifestation, cytology, pathology and immunologic histochemistry. Ultrastructural features strongly indicated the difference in three various diseases, although all the immunologic markers showed B-cell type.It is concluded that electron microscopic examination is of a definite significance in the diaguosis and successful treatment.
文摘BACKGROUND Malignant lymphoma is a rare form of gallbladder malignancy.Most of these malignancies are diffuse large B-cell lymphomas or mucosa-associated lymphoid tissue-type lymphomas;however,Burkitt’s lymphoma of the gallbladder is extremely rare,and only two previous reports are available in the literature.Herein,we report a rare case of Burkitt’s lymphoma of the gallbladder mimicking gallbladder adenocarcinoma.CASE SUMMARY An 83-year-old man with no abdominal complaints was found to have a gallbladder tumor and periportal lymph node enlargement on computed tomography(CT)performed for hypertension screening.His laboratory data revealed slightly elevated serum levels of carcinoembryonic antigen and soluble interleukin 2 receptor.Imaging examinations revealed two irregular and contrastenhanced masses extending into the gallbladder lumen,but these did not infiltrate the serosa.Moreover,a periportal lymph node had enlarged to 30 mm.Based on these findings,we diagnosed the patient as having gallbladder adenocarcinoma with lymph node metastasis,which was treated using bile duct resection with gallbladder bed resection and periportal lymph node dissection.However,the patient was finally diagnosed as having Burkitt’s lymphoma.Although the surgical margin was pathologically negative,recurrence was noted at the hepatic radical margin and superior pancreaticoduodenal lymph nodes on positron emission tomography/CT soon after discharge.Thus,he was referred to a hematologist and started receiving treatment with reduced-dose cyclophosphamide,doxorubicin,vincristine,and prednisone.CONCLUSION Burkitt’s lymphoma can occur in the gallbladder.Biopsy can be useful in cases with findings suggestive of gallbladder malignant lymphoma.

文摘Objective:To characterize modified R-CODOX-M/IVAC-based chemotherapy to lower the severe adverse events in Chinese adult patients with sporadic Burkitt lymphoma.Methods:We enrolled a retrospective cohort including 123 adult patients with untreated sporadic Burkitt lymphoma from August 2008 to September 2019 at Sun Yat-sen University Cancer Center.We studied a dose-modified and long-course R-CODOX-M/IVAC regimen utilizing a low dose of 1.0 g/m2/cycle cyclophosphamide,2 g/m2/cycle methotrexate,4,500 mg/m2/cycle ifosfamide,and 4.0 g/m2/cycle cytarabine.Forty-nine patients with low risk disease underwent 4–6 cycles of dose-modified R-CODOX-M-based chemotherapy.Seventy-four patients with high risk disease underwent 6–8 cycles of dose-modified alternating R-CODOX-M/IVAC regimens.Results:The objective remission was 87.0%.The event-free survival rate and overall survival at 3 years were 81.2%and 92.1%,respectively.Major grade 3–4 adverse events included leukopenia(91.9%),anemia(58.5%),thrombocytopenia(73.2%),and febrile neutropenia(48.8%).A total of 26.0%and 37.4%of patients received red blood cell and platelet transfusions,respectively.We observed 4 cases(3.3%)of septic shock after chemotherapy.Two treatment-related deaths occurred from severe infection.Conclusions:The modified R-CODOX-M/IVAC chemotherapy regimen was effective for sporadic Burkitt lymphoma in the Chinese population,with a lower toxicity than standard regimens.
文摘Background: Obesity in pediatric ALL survivors is a well recognized late effect. Hence the present study examines the BMI-for-age of Indian childhood ALL and NHL survivors. Method: A retrospective study of 118 ALL/NHL survivors and 138 age sex matched was carried out. From the recorded heights and weights were body mass index (BMI) was computed. The survivor data was compared with 138 controls from the data set collected by investigators previously. Results: 82.8% of patients had BMI-for-age in 5th-84th percentile (healthy) at time of diagnosis and at inclusion in the study. Comparison of BMI of survivors with matched controls was not significant. However, The mean BMI-for-age for younger patients (3 to 12 years) was significantly higher than mean BMI-for-age of matched controls. Distribution of data by time elapsed from therapy was significant. Overweight/obesity was observed among the survivors who were off therapy for two years with increase in after four years post-therapy. Conclusion: Our preliminary study indicates late effects of therapy and points to the need of long term assessment of the survivors, even though majority of them were within the normal weight range.
文摘Objective: To examine whether differences in treatment patterns and health care costs exist among chronic lymphocytic leukemia (CLL) and non-Hodgkin’s lymphoma (NHL) patients receiving rituximab in a hospital outpatient setting versus those receiving rituximab in a physician office/community clinic setting. Methods: This retrospective database study used medical and pharmacy claims (1/2007-7/2012) from a large US health plan. Patients ≥18 years with ≥2 rituximab claims and ≥2 claims for either NHL or CLL were identified. The date of the first rituximab claim were set as the index date, and differences in treatment patterns and health care costs were examined during the period following the index date. Costs were adjusted for patient characteristics using a multivariate regression model. Results: A total of 4441 patients were identified;3167 received rituximab in the office/clinic setting, and 1274 in the hospital outpatient setting. From 2007 to 2012, the percentage of patients receiving rituximab in the hospital outpatient setting increased from 22% to 39%. Patients treated in the hospital outpatient setting vs. the office/clinic setting had fewer average counts of rituximab infusions (5.60 vs. 7.49, p 0.001), higher total health care costs (cost ratio = 1.325, p 0.001), higher infusion day drug and administration costs (cost ratio = 1.509, p 0.001), and higher rates of ER visits and inpatient stays (both p 0.001). Conclusions: These findings suggest that site of care may impact treatment patterns and costs of patients receiving rituximab, and additional research is needed to better understand the reason(s) for these differences by site of service.
