ABSTRACT

Objective: To observe whether the history of solid tumors affects the treatment response and survival situation of patients with diffuse large B-cell lymphoma (DLBCL) . Methods: A retrospective study was conducted in 836 patients with DLBCL who were treated in the Department of Hematology at Ruijin Hospital from 2013 to 2018. Among them, 34 DLBCL patients who had the history of solid tumors were classified into double cancer group. From 802 patients without history of solid tumors, 68 DLBCL patients were selected as control group, using 1∶2 matching on propensity scores for age, gender, IPI score and etc. All patients included in the study had follow-up interviews through medical record and telephone for mortality from any cause. Treatment response and 3-year overall survival (OS) and progression-free survival (PFS) of two groups were analyzed. Results: The complete remission rates after RCHOP (Rituximab+Cyclophosphamide+Vincristine+Adriamycin 50 mg/m(2) or Epirubicin or Liposome Adriamycin+Prednisone) regimen were 79.4% and 67.6% in the double cancer group and the control group, respectively (P=0.210) . Among the 102 patients, 6 patients died in the double cancer group while 24 patients died in the control group and the median survival time of both two groups were not reached. The 3-year OS were (74.7±9.5) % and (63.5±6.1) % (χ(2)=2.791, P=0.095) , while 3-year PFS were (72.1±8.8) % and (54.3±6.4) % (χ(2)=1.400, P=0.237) in the double cancer group and the control group, respectively. Conclusion: The history of solid tumors didn't affect DLBCL patients' treatment response and short-term survival.

ABSTRACT

Objective: To evaluate the outcomes of splenectomy in the treatment of relapsed/refractory autoimmune hemolytic anemia (AIHA). Methods: Retrospective analysis was performed in 30 cases with relapsed/refractory AIHA who were treated with splenectomy in our hospital. The pre- and post-operative blood routine indexes and responses were followed up. Results: Among the 30 relapsed/refractory AIHA patients, 20 were pure AIHA (including 13 patients with warm antibody AIHA, 2 with warm-cold double antibody AIHA and 5 with Coombs negative AIHA) and 10 were Evans syndrome. The short-term response was evaluated 10-14 days after operation, and the overall response rate (ORR) of short-term response was 90% [12 cases in complete response (CR), 6 cases in partial response (PR)] in 20 therapeutic evaluable cases. Among 13 patients with long-term follow-up data, except 3 patients with Evans syndrome died (2 cases were refractory to splenectomy, 1 case relapsed after surgery), the ORR of 10 patients with relapsed/refractory pure AIHA at 6 months and 12 months were 90% (9/10) and 70% (7/10), respectively, with a median follow-up of 14 (4-156) months. At the end of follow-up, 3 cases had maintained CR for more than 3 years. Conclusion: The short-term response of splenectomy as a second-line treatment for relapsed/refractory AIHA is satisfactory, and long-term outcome of splenectomy is up to 70% at 1 year. Approximately one-third of patients could maintain sustained remission.

ABSTRACT

Objective: To compare the efficacy of induction chemotherapy with or without autologous hematopoietic stem cell transplantation (auto-HSCT) for newly diagnosed young diffuse large B cell lymphoma (DLBCL) patients. Methods: The retrospective study was performed in 90 cases of young patients (≤60 years) with newly diagnosed DLBCL and an age-adjusted International Prognostic Index (aa-IPI) score of 2 or 3. All of them were treated with R-CHOP (32 cases, rituximab combined with CHOP), dose-intensive regimens (DA-EPOCH, Hyper CVAD/MA or ESHAP) combined with or without rituximab (25 cases), and consolidated with up-front auto-HSCT (33 cases), respectively. The efficacy and the potential predictors were evaluated. Results: ①The median age of 90 patients was 43 (18-60) years old. The median follow-up time was 42 (3-110) months. ②The 5-year progression-free survival (PFS) for R-CHOP group, dose-intensive chemotherapy group and auto-HSCT group were (33.5±10.7) %, (55.3±10.1) % and (65.8±13.6) % (P=0.012), the 5-year overall survival (OS) were (49.7±9.0) %, (61.6±10.2) % and (78.6±7.8) % (P=0.035), respectively. There was no significant difference in 5-years PFS and OS between the R-CHOP group and dose-intensive chemotherapy group (P=0.519, P=0.437) compared with that of the dose-intensive chemotherapy group, auto-HSCT group has higher 5-year PFS (P=0.042). ③ When stratified with IPI score, the high-risk group treated with auto-HSCT (26 cases) showed similar 5-years PFS and 5-years OS to those in the low-risk group with chemotherapy alone (12 cases were in R-CHOP group and 8 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3 ±14.3)%, (58.3 ±18.6)% and (51.4±18.7)%, respectively, P=0.686; 5-years OS were (69.2±13.9)%, (62.5±15.5)% and (58.3±18.6)%, respectively, P=0.592]. ④However, the high-risk group treated with auto-HSCT (26 cases) showed superior 5-years PFS (P=0.002) and 5-years OS (P=0.019) compared to the high-risk group with chemotherapy alone (20 cases were in R-CHOP group and 17 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3±14.3)%, (41.1±13.5)% and (21.9±11.6)%, respectively; 5-years OS were (69.2±13.9)%, (51.5%±14.0)% and (35.4±13.6)%, respectively]. ⑤In the univariate analysis, as a whole, patients diagnosed with GCB subtype had higher 3-years PFS (P=0.022) and 3-years OS (P=0.037) compared to non-GCB subtype patients; in subgroup analysis, patients diagnosed with GCB subtype had higher 3-years PFS and 3-years OS compared to non-GCB subtype both in R-CHOP group (P=0.030, P=0.041) and dose-intensive chemotherapy group (P=0.044, P=0.047), but not in auto-HSCT group (P=0.199, P=0.093). ⑥In the multivariate analysis, different molecular classification (GCB/non-GCB) was an independent predictor for PFS and OS both in R-CHOP group [HR=0.274 (95% CI 0.094-0.800), P=0.018; HR=0.408 (95% CI 0.164-1.015), P=0.045] and dose-intensive chemotherapy group [HR=0.423 (95% CI 0.043-1.152), P=0.048; HR=5.758 (95% CI 0.882-6.592), P=0.035]. However, there was no significant difference in PFS and OS for auto-HSCT group between GCB/non-GCB patients. Conclusion: Induction chemotherapy followed by up-front auto-HSCT has significant effect on efficacy for young and untreated patients with high risk DLBCL. Combined with induction chemotherapy followed by up-front auto-HSCT could improve the prognosis of non-GCB patients.

ABSTRACT

OBJECTIVE@#To investigate the clinical outcome of the patients with primary diffuse large B-cell lymphoma(DLBCL).@*METHODS@#Clinical data of 148 patients with DLBCL in our hospital and cancer hospital from March 2006 to April 2016 were retrospectively analyzed. Kaplan-Meier analysis was used to estimate progression-free survival(PFS)and overall survival(OS).@*RESULTS@#5-year OS and PFS rates were 85% and 69%,respectively. The survival analysis showed that 5-year OS rate of R-CHOP group was significantly higher than that of CHOP alone group(89% vs. 70%,P60 years),poor ECOG score(≥2),advanced stage(Ⅲ-Ⅳ),higher IPI score(≥3),CHOP alone and absence of radiotherapy related with poor survival rate. Furthermore,multivariate analysis showed that age>60 year significantly related with the worse OS.@*CONCLUSION@#Age >60 year is an important independent prognostic factor to predict worse OS or PFS.

ABSTRACT

OBJECTIVE@#p53 gene, as "the guardian of the genome", is the most widely studied tumor suppressor gene. Previous studies have shown that about 50 percent of tumors have P53 dysfunction. This article aims to retrospectively analyze the correlation between p53 rs1625895 polymorphism and the prognosis of patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#PCR combined with Sanger sequencing were used to detect rs1625895 genotype in 384 DLBCL patients. The relationship between rs1625895 polymorphisms and the clinical characteristics, first-line therapeutic effects and the prognosis of the patients were analyzed.@*RESULTS@#Among all the patients, 2 (0.5%) patients with AA genotype, 34 (8.9%) patients with AG genotype and 348 (90.6%) patients with GG genotype were identified. The patients with different rs1625895 genotypes did not have any difference in terms of age, gender, B symptoms (developing any of the following symptoms: unexplained recurrent fever (often above 38 °C), night sweats, and unexplained weight loss of 10% within 6 months ), erythrocyte sedimentation rate (ESR), international prognostic index (IPI) and molecular subtype (P>0.05). The overall response rate (ORR) was 82.9% and 82.8% in AA/AG and GG, respectively. There was no significant difference between the first-line therapeutic effects of the two groups (P>0.05). And there was also no difference between A allele carriers and homozygous G allele carriers for the 5-year progressionfree survival rate (PFS) (71.8% vs. 62.3%, χ2=1.351, P=0.245) and 5-year overall survival rate (OS) (72.2% vs. 64.1%, χ2=1.267, P=0.260). But in the subgroup with Germinal Center B-cell (GCB) type, the patients carrying A allele for rs1625895 had an obviously longer PFS (91.7% vs. 72.7%, χ2=4.493, P=0.034) and OS (91.7% vs. 76.7%, χ2=4.246, P=0.039) compared with the patients homozygous for the G allele. As for the patients with non-GCB subtype, there was no significant difference in PFS and OS between different rs1625895 genotypes (P>0.05). According to whether the first-line regimen contained rituximab or not, the patients were divided into two groups treated with cyclophosphoramide, doxorubicin, vincristine and prednisone (CHOP) or with rituximab and CHOP (R-CHOP). But in both subgroups, there was no significant difference in the 5-year PFS and OS between the AA/AG and GG patients, too (P>0.05).@*CONCLUSION@#For DLBCL patients receiving CHOP regimen chemotherapy in the first line, p53 rs1625895 cannot predict the clinical efficacy and prognosis of the patients, but in the patients with GCB subtype, this polymorphism may be a prognostic indicator.

ABSTRACT

The term autoimmune cytopenias is referred to a heterogeneous group of diseases characterized by a reduced peripheral blood cell counts in one or more cellular series, because an immunological disorder. The first line therapy is steroids, followed by splenectomy or immunesupressant therapy in non-responders. Rituximab is an anti CD20 monoclonal antibody used as a third line in refractory patients or as an alternative to splenectomy. We present a retrospective study of nine patients with autoimmune cytopenias treated in a public hospital setting with rituximab. Five patients with the diagnosis of inmune thrombocytopenic purpura received it, all of them achieved hematological response (4 complete and one partial). The median time to the best response was 6 weeks, staying in this category after 6 months of follow up. Four patients with autoimmune hemolytic anemia received rituximab, three of them achieving partial response and one was lost from follow up. No severe adverse effects related to rituximab were registered.

ABSTRACT

Objective: To explore the prognostic value of the international prognostic index (IPI), the national comprehensive cancer network IPI(NCCN-IPI)and the age-adjusted IPI (aa-IPI) in diffuse large B cell lymphoma. Methods: A total of 311 patients with de novo diffuse large B-cell lymphoma (DLBCL) diagnosed from 2003 to 2012 in Nanfang hospital were included. All patients were divided into CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) and R-CHOP (rituximab, CHOP) groups. Survival analysis was compared among IPI, NCCN-IPI and aa-IPI models. Discrimination of three different prognostic models was assessed using the Harrell's C statistic. Results: A total of 311 patients were analyzed. Among them, 128 patients were treated with CHOP regimen and other 183 patients were treated with R-CHOP regimen. In CHOP groups, both NCCN-IPI (5-year OS: 59.7% vs 26.8%, P<0.001) and aa-IPI (5-year OS: 71.0% vs 25.0%, P<0.001) showed better risk stratification for low-intermediate and high-intermediate group than the IPI (5-year OS: 47.6% vs 36.6%, P=0.003). However, in the patients treated with R-CHOP, NCCN-IPI showed better risk stratification in low, low-intermediate, high-intermediate groups (5-year OS: 96.0% vs 83.0% vs 66.5%, P=0.009). According to the Harrell's C statistic, C-index of IPI, NCCN-IPI and aa-IPI for overall survival (OS) were 0.546, 0.667, 0.698 in CHOP group and 0.611,0.654, 0.695 in R-CHOP group respectively. In patients younger than 60 years old, C-index of IPI, NCCN-IPI and aa-IPI for OS were 0.534, 0.675, 0.698 in CHOP group and 0.584, 0.648, 0.695 in R-CHOP respectively. Conclusion: The NCCN-IPI is more powerful than IPI and aa-IPI in DLBCL patients receiving R-CHOP. aa-IPI is a preferable model in predicting prognosis than IPI and NCCN-IPI in anthracycline-based chemotherapy without rituximab.

ABSTRACT

Objective: To investigate the long term efficacy of COPADM regimen in the treatment of Burkitt lymphoma (BL). Methods: The clinical data of 39 patients with BL from April 2006 to June 2017 were retrospectively analyzed. According to different chemotherapy regimens, the patients were divided into COPADM group and control group. Results: ①Of 39 BL patients, 26 were male and 13 female. The median age was 30 (11-63) years old, including 25 younger than 40 and 14 older than 40. Among them, 33 patients were in stage Ⅲ-Ⅳ, 13 patients had B symptoms and 25 patients were IPI score≥3. ② Twenty patients treated with COPADM regimen (COPADM group), the 3 year overall survival (OS) and progression-free survival (PFS) were (83.5±2.6)% and (73.2±3.1)%, respectively. Nineteen patients in the control group had a 3-year OS and EFS of (47.4±2.4) % and (42.1±2.4) %, respectively. There were significant differences in OS and EFS between the two groups (all P<0.001). ③Of the 20 patients in COPADM group, 12 were younger patients (age≤40 years), their 3-year OS and EFS were (93.7±3.9)% and (83.3±5.4)%, respectively. The other 8 patients were older than 40 years old, and their 3-year OS and EFS were (48.3±8.5) %, (37.6±6.0) %, respectively. Both OS and EFS in younger patients was significantly better than older patients (P=0.004, P=0.045). ④ There were 24 patients treated with combination of Rituximab, their 3-year OS and EFS were (73.9±9.2)% and (69.9±9.6)%, respectively. The other 15 patients were treated without Rituximab, and their 3-year OS and EFS were (51.3±13.3) % and (38.1±12.9) %, respectively. There were significant differences in OS and EFS between the two groups (P=0.042, P=0.008). Conclusion: COPADM regimen may improve the efficacy of BL. COPADM combined with Rituximab enables BL patients with greater benefit. The prognosis is significantly worse in patients older than 40 years old than in those less than 40 years old.

ABSTRACT

Objective: To summarize and investigate the characteristics, prognosis and treatments of chronic lymphocytic leukemia (CLL) patients with trisomy 12 by using FISH (CEP12). Methods: Clinical data of 330 CLL patients were analyzed retrospectively by using FISH (CEP12) to detect trisomy 12 from May 2003 to April 2015. The clinical data and laboratory characteristics of CEP12 positive patients (70 cases) were compared with those CEP12 negative patients (260 cases). Results: Compared with CEP12 negative CLL patients, the proportion of hepatomegaly (13.6% vs 4.0%, P=0.011) and LDH>247 U/L (43.3% vs 18.5%, χ(2)=15.892, P<0.001) in CEP12 positive CLL patients were much higher, respectively. There were no significant differences between age, sex, clinical stage, β(2)-microglobulin level, IGHV mutation ratio and splenomegaly/lymphadenopathy in these two subgroups. However, compared with CEP12 negative patients, CEP12 positive patients had higher ratio of FMC7 (23.8% vs 12.7%, χ(2)=4.730, P=0.030), and lower ratio of CD23 (95.2% vs 99.6%, P=0.033). The overall response rates (ORR) in Fludarabine (without Rituximab), Rituximab (with or without Fludarabine) and the traditional chemotherapy group (chlorambucil, CHOP or CHOP-like) were 77.5% (31/40), 84.8% (56/66) and 45.4% (50/110), respectively. The ORR of the traditional chemotherapy group was lower than that of the Fludarabine group and Rituximab group. For CEP12 positive patients, the ORR was inferior to CEP12 negative patients when only using Fludarabine (P<0.05). However, when using Rituximab, the difference could be eliminated, and the ORR was even a little higher in CEP12 negative patients (91.7% vs 81.0%, P=0.306). Compared with CEP12 negative patients, there were no significant differences in progression-free survival (PFS) (χ(2)=0.410, P=0.478) and overall survival (OS) (χ(2)=0.052, P=0.180) for CEP12 positive patients whom the median time from diagnosis to start treatment and OS time was 22.6 (95%CI 15.4-31.7) and 118.5 (95%CI 74.5-162.4) month while the 5-year PFS and OS were (52.9±7.6)% and (74.8±6.6)%. Conclusions: CEP12 positive CLL patients are more common in hepatomegaly and higher level of LDH. The traditional chemotherapy treatment had the lowest efficacy, and the curative effect of single use of fludarabine is not as good as that of CEP12 negative patients, however, when using Ritaximab, the efficacy could be comparable.

ABSTRACT

ABSTRACT INTRODUCTION: Tumors of the lip and oral cavity differ in various aspects; therefore a clarification of the distinctions among these sites may help to better understand the biologic behavior of neoplasms occurring in these locations. OBJECTIVE: Considering that angiogenesis and lymphangiogenesis are two major elements that can influence various aspects of tumor biology, we aimed to compare these factors between squamous cell carcinoma of the lower lip and oral cavity. METHODS: A total of 84 primary squamous cell carcinomas including 45 oral and 39 lower lip tumors were selected and immunohistochemically stained with monoclonal antibody against D2-40 and CD105. Mean microvessel density was assessed in tumoral tissue, while lymphatic vessel density was calculated in both neoplastic tissue and invasion front. Data were statistically analyzed using t-test and p-values of <0.05 were considered significant. RESULTS: We found a mean microvessel density ± standard deviation of 31.94 ± 18.9 in oral cavity and 27.54 ± 20.8 in lower lip squamous cell carcinomas, with no significant difference (p = 0.32). Mean lymphatic vessel density ± standard deviation was 13.05 ± 8.2 and 16.57 ± 10.79 in of oral cavity and lower lip neoplastic tissue, respectively. The corresponding values were 9.94 ± 5.59 and 12.50 ± 7.8 in the invasive front. Significant differences were not observed in either of the lymphatic vessel density variables between the two sites. CONCLUSION: According to our results, it seems that the search for additional factors other than those related to the vasculature should continue, to help clarify the differences in biologic behavior between lower lip and oral cavity squamous cell carcinomas.


Resumo Introdução: Os tumores de lábio e da cavidade oral diferem em vários aspectos; portanto, o conhecimento das diferenças entre eles pode ajudar na melhor compreensão do comportamento biológico das neoplasias que ocorrem nesses locais. Objetivo: Considerando que a angiogênese e a linfangiogênese são dois elementos importantes que podem influenciar diversos aspectos da biologia dos tumores, objetivamos comparar esses fatores entre o carcinoma de células escamosas (CCE) de lábio inferior e da cavidade oral. Método: No total, foram selecionados 84 CCEs primários (45 tumores da cavidade oral e 39 tumores de lábio). Esses tumores foram corados por processo imunohistoquímico com anticorpo monoclonal anti-D2-40 e CD105. Avaliamos a densidade média de microvasos (DMV) no tecido tumoral, enquanto que a densidade vascular linfática (DVL) foi calculada tanto no tecido neoplásico como no front de invasão. Os dados foram estatisticamente analisados com o uso do teste t e valores de p < 0,05 foram considerados significantes. Resultados: Chegamos a uma média para DMV ± DP de 31,94 ± 18,9 para CCEs na cavidade oral e de 27,54 ± 20,8 no lábio inferior, sem diferença significante (p = 0,32). As médias para DVL ± DP foram de 13,05 ± 8,2 e 16,57 ± 10,79 no tecido neoplásico da cavidade oral e lábio inferior, respectivamente. Os valores correspondentes foram 9,94 ± 5,59 e 12,50 ± 7,8 no front invasivo. Não foram observadas diferenças significantes nas duas variáveis DVL entre os dois locais. Conclusão: De acordo com os nossos resultados, a pesquisa por fatores adicionais, além daqueles relacionados à vasculatura, deve ter continuidade, para auxiliar no esclarecimento das diferenças do comportamento biológico entre CCEs no lábio inferior e na cavidade oral.

ABSTRACT

<p><b>OBJECTIVE</b>To investigaate the clinical efficacy of Aidi injection-asisted R-CHOP chemotherapy for the treatment of diffuse large B-cell lymphoma (DLBCL).</p><p><b>METHODS</b>Fifty-one patients diagnosed as DLBCL in our department from February 2005 to September 2015 were randomly divided into 2 groups. Out of them, 26 patients in one group received R-CHOP chemotherapy asisted by Aidi intravenous infection (Aidi+R-CHOP group), 25 patients were in another group received only R-CHOP chemotherapy (R-CHOP group), 3 weeks for one course, to tally continuous 2 courses. The recent therapeutic efficacy, adverse events, quality of life, sIL-2R level and long-term survival rate were compared between 2 groups.</p><p><b>RESULTS</b>The efficacy of the Aidi+R-CHOP group was significantly higher than that of the R-CHOP group (P<0.05); the incidences of neutropenia and thrombocytopenia were significantly lower than the R-CHOP group (P<0.05); besides, KPS scores were significantly higher than in the R-CHOP group (P<0.05); sIL-2R level in the Aidi+R-CHOP group after treatment was significantly lower than that in the R-CHOP group (P<0.05), however, these data were not statistically different between the two groups before treatment. In addition, 3 and 5-year progression-free survival (PFS) rate in the Aidi+R-CHOP group was significantly higher than that in the R-CHOP group.</p><p><b>CONCLUSION</b>The use of Aidi injection-asisted R-CHOP chemotherapy for treating patients with diffuse large B-cell lymphoma can increase the patient's tolerance to chemotherapy, improve their quality of life, also reduce the side-effects of chemotherapy, and the trerapeutic effect is more significant than that of R-CHOP regimen alone, thus improving the overall therapeutic efficacy of patients with diffuse large B-cell lymphoma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficiency and safety of rituximab and dexamethasone combined with cyclophosphamide for treating patients with relapsed and refractory immune thrombocytopenia (ITP).</p><p><b>METHODS</b>Twelve patients with relapsed and refractory immune thrombocytopenia were prospectively enrolled in this study, and received rituximab 375 mg/m(2) once a week for 4 weeks, dexamethasone 40 mg once a day for consecutive 4 days, and cyclophosphamide 500 mg/m(2) biweekly for 2 weeks. The levels of IFN-r and IL-4 in peripheral blood of patients were measured by enzyme-linked immunosorbent assay (ELISA), and the percentages of Breg, Treg and Th17 cells were detected by flow cytometry before and after treatment. Efficiency was evaluated according to platelet counts, and side effects were observed.</p><p><b>RESULTS</b>Six out of 12 patients reached to complete remission and 4 patients reached to partial remission, with the total response rate 83.33%. The platelet counts [(115.42 ± 76.60) × 10(9)/L] after treatment were significantly higher than that before treatment [(115.42 ± 76.60) × 10(9)/L] (P < 0.001). The ratio of IFN-r/ IL4 after treatment (5.89 ± 2.30) was very significantly lower than that before treatment (7.00 ± 2.73) (P = 0.002). The percentage of Breg cells after treatment [(21.27 ± 4.28)%] were much significantly higher than that before treatment [(15.48 ± 1.67)%] (P < 0.001). The ratio of Treg/Th17 after treatment (3.07 ± 1.50) was significantly higher than that before treatment (0.98 ± 0.45) (P < 0.001). Infusion reaction was observed in 1 patient, secondary hypertension and hyperglycemia were in 1 patient, and pneumonia in 2 patients.</p><p><b>CONCLUSION</b>Rituximab and dexamethasone combined with cyclophosphamide can improve the outcomes of patients with relapsed and refractory immune thrombocytopenia patients and they were well tolerated, its mechanism may be related with the balance between T cell sunsets and Treg cells.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the prognostic value of different models in patients with early-stage diffuse large B-cell lymphoma (DLBCL).</p><p><b>METHODS</b>Early-stage DLBCL patients diagnosed from January 2000 to December 2012 were analyzed retrospectively. All patients received with at least 2 cycles of immunochemotherapy R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) with or without radiotherapy. The prognostic value of international prognostic index (IPI) , revised IPI (R-IPI) and enhanced IPI (NCCN-IPI) was compared.</p><p><b>RESULTS</b>Ninety-seven cases of early-stage DLBCL were included in the study. The median age was 58 years (15-88 years) with a median follow-up of 34.7 months (range 7.3-77.4 months). The expected 5-year overall survival (OS) for entire group was 82%. There was no patient in the high risk group according to IPI or NCCN-IPI. According to IPI, the 5-year OS in the low, low intermediate, high intermediate risk groups were 95%, 38% and 60%, respectively. According to R-IPI, the 5-year OS in the very good, good, and poor risk groups were 93%, 75% and 60%, respectively. According to NCCN-IPI, the 5-year OS in the low, low intermediate, high intermediate risk groups were 92%, 85% and 29%, respectively.</p><p><b>CONCLUSION</b>NCCN-IPI would be of an ideal prognostic model for early-stage DLBCL patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the evaluation value of invasion area PET-CT scanning for chemotherapeutic efficacy and prognosis of patients with lymphoma.</p><p><b>METHODS</b>A total of 98 newly diagnosed patients with lymphoma received the chemotherapy by R-CHOP protocol, the PET-CT scan of whole body and invasion area was performed after 6 cycle of chemotherapy. The invasion area was determined by PET-CT scan results before chemotherapy. The difference of clinical stage, clinical efficacy, radiation dose and scanning time were compared between PET-CT scanning of whole body and invasion area.</p><p><b>RESULTS</b>The clinical stages of PET-CT scaning of whole body and invasion area were complete consistent, the consisitent rate of clinical stages from whole body and invasion area PET-CT scaning with Ann Arbor staging was 95.9%(94/98). Whole body PET-CT scan showed that 68 cases achieved CR, 26 cases achieved PR, 1 case achieved SD, 3 cases achieved PD. PET-CT scan of invasion area showed that 68 cases achieved CR, 24 cases achieved PR, 2 cases achieved SD, and 4 cases achieved PD; the PET-CT scan results of the whole body and the invasion area was consistent with CR. In 68 patients with CR, the radiation dose of CT, PET and PET-CT was significantly lower than that of whole body PET-CT, and the scanning time was significantly less than that of whole body PET-CT (P < 0.05).</p><p><b>CONCLUSION</b>For clinical efficicacy with CR patients, the scan results of whole body and invasion area PET-CT are consistent, and the PET-CT invasion area can significantly reduce the radiation dose and scanning time; and for PR, SD and PD patients, the whole body PET-CT scan should be performed to evaluation clinical efficiency.</p>

ABSTRACT

Resumo O maior entendimento das bases fisiopatológicas e do comportamento das vasculites sistêmicas, aliado ao desenvolvimento de regimes terapêuticos com perfil de segurança e eficácia cada vezes melhores, modificou drasticamente o prognóstico dos pacientes diagnosticados com essas entidades clínicas. Recentemente, o emprego do rituximabe no tratamento de pacientes com vasculites ANCA associadas em ensaios clínicos randomizados se mostrou uma opção importante em casos selecionados, especialmente pacientes refratários ou intolerantes à terapia-padrão com ciclofosfamida e corticosteroides. O presente artigo traz o relato de sete casos de vasculites sistêmicas com tratamento bem-sucedido com rituximabe.


Abstract The greater understanding of pathophysiology and behavior of systemic vasculitis, together with the development of therapeutic regimens with increasingly better safety and efficacy profiles, dramatically changed the prognosis of patients diagnosed with these clinical entities. Recently, the use of rituximab in the treatment of patients with ANCA-associated vasculitis in randomized clinical trials showed an important alternative in selected cases, especially patients refractory or intolerant to standard therapy with cyclophosphamide and corticosteroids. This article presents the report of seven cases of systemic vasculitis successfully treated with rituximab.

ABSTRACT

To determine the impact of Rituximab and international prognostic index score on survival in diffuse large B-cell lymphoma patients. The retrospective study was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from January to May 2013 and comprised record of patients with diffuse large B-cell lymphoma who were treated from 2007 to 2010. Baseline international prognostic index score, stage at presentation were noted and the records were divided into two groups A and B on the basis of the type of chemotherapy. SPSS 19 was used for statistical analysis. Of the 93 patients in the study whose records were reviewed, 54[58%] were men. Overall median age was 43 years [range: 18-76]. Stages at presentation were stage-I 14 [15.1%], stage-II 41 [44.1%], stage-III 20 [21.5%] and stage-IV 18 [19.4%]. International prognostic index risk categorisation was low risk 59[63.4%], low intermediate risk 23[24.7%], high intermediate risk 10[10.8%] and high risk 1[1.1%]. There were 31[33%] patients in Group A and 62[67%] in Group B. Median follow-up was 3.9 years [range: 1.2-6.1]. Overall survival at 4 years was 66.4%; for Group A 65.3% and for Group B 66.7% [p<0.4]. On the basis of risk categories, overall survival was statistically significant [p<0.001] between the groups. International prognostic index risk categorisation had statistically significant impact on survival. However, there was no evidence of a significant survival benefit between types of chemotherapy. Further controlled trials are needed in this regard

ABSTRACT

<p><b>OBJECTIVE</b>This study was aimed to investigate the morphological, immunophenotype, cytogenetic characteristics, clinical and therapy features in one elderly patient with chronic lymphocytic leukemia (CLL) combined with invasive aspergillose infection(IAI).</p><p><b>METHODS</b>The morphological features of bone marrow cells from patient were observed by light microscope, the immunophenotype were detected by flow cytometry, the cytogenetic characteristics were assayed by conventional chromosomal analysis and fluorescence in situ hybridization (FISH).</p><p><b>RESULTS</b>at onset of disease, the patient was diagnosed as B-CLL, Rai stage is II. He was treated with a course of RF(fludarabine 50 mg×5, rituximab 600 mg×5) chemotherapy, and achived complete remission (CR) lasting for five years, then the patient was treated with multiple courses of chemotherapy and maintained at a steady state of disease. After the last chemotherapy, this patient developed a fever, his temperature fluctuated at 37.2-38.7°C, the lung CT showed the presence of massive shadow, repeated 1-3-β-D-glucan test was positive,and he was considered as invasive aspergillosis infection, voriconazole was intravenously injected him for 2 months, his lung CT showed better efficacy. However, the leukemia continued progress, his hemogram was extremely low, invasive aspergillosis infection relapsed,voriconazole treatment was poor effect,ultimately this patient died of the rapid progress of leukemia and multiple organ invasive aspergillosis. Autopsy showed chronic lymphocytic leukemia with multiple metastases and multiple organ invasive aspergillosis.</p><p><b>CONCLUSION</b>invasive aspergillosis is a serious complication for CLL patients,once occurs, the prognosis is poor,so early diagnosis and prophylactic antifungal therapy may reduce fungal infection complication.</p>
