Clinical data of 13 patients with primary pulmonary lymphoma(PPL),treated in Tianjin Medical University Cancer Hospital from January 1999 to December 2009,were retrospectively reviewed.There were 8 patients with mucosa-associated lymphoid tissue(MALT)marginal zone lymphoma,2 patients with diffuse large B cell lymphoma,1 patient with NK/T cell lymphoma,1 patient with nodular sclerosis Hodgkin's lymphoma,and 1 patients with lymphocytic predominance Hodgkin's lymphoma.The main clinical symptoms were cough,fever,night sweat and weight loss.Two patients did not have any symptoms.Pulmonary consolidation shadows and multiple nodules were the main findings of CT scan.An air bronchogram was often seen in the consolidation imaging.The overall 5-year survival rate was 9/13 for all patients;while that was 7/8 for MALT marginal gone lymphoma.

OBJECTIVE:To observe the clinical efficacy of taxol combined with cisplatin neoadjuvant chemotherapy in the treatment of esophageal cancer and effects on serum tumor markers in patients with esophageal cancer. METHODS:100 patients with esophageal cancer were randomly divided into control group(50 cases) and observation group(50 cases). Observation group was given taxol+Cisplatin injection(TP)neoadjuvant chemotherapy,given 175 mg/m2 taxol by intravenous infusion,d1-5. And ev-ery 5 d was a treatment course,the regimen was adjusted based on patients’efficacy;control group was given conventional sur-gery and TP after surgery,the same usage and dosage as observation group,it lasted for 4 courses. Clinical efficacy,high mobility protein B1(HMGB1),carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC-Ag) level in 2 groups before and after treatment were observed,objective response rate,disease control rate,the incidence of toxicity and severe toxicity,inci-dence of postoperative complications and survival rate of postoperative 1,3 and 5 years were recorded. RESULTS:After treatment, objective response rate in observation group was significantly higher than control group,HMGB1,CEA and SCC-Ag levels were significantly lower than before and control group,HMGB1 and CEA levels in control group were significantly lower than before, the differences were statistically significant(P<0.05);there were no significant differences in the disease control rate,chemothera-py-related toxicity,severe toxicity,incidence of postoperative complications,survival rate of postoperative 1,3 and 5 years and the median survival time between 2 groups(P>0.05). CONCLUSIONS:Taxol combined with cisplatin neoadjuvant chemotherapy can significantly improve the efficacy of patients with esophageal cancer and reduce the levels of cancer-related indicators,with good safety.

Objective To explore the dynamic changes of serum HMGB1, CEA and SCC as well as the value in the evaluation of prognosis of patients with esophageal squamous cell carcinoma resection. Methods The dynamic changes in serum levels of HMGB1, CEA and SCC were measured respectively in 100 patients preopera-tively as well as a month after esophagectomy. The relationships between the changes of serum tumor markers and the clinical efficacy were analyzed. Results The 5-years survival rate of the CEA, SCC and HMGB1 negative peo-ple before operation was significantly higher than that of the positive patients (P < 0.05). The 5-years survival rate of those patients with all three markers negative before operation was significantly higher than that of those patients with the three markers positive (P < 0.01). The Median Survive Time of the patients with the levels of all three markers decreased after operation was longer than those with the levels of all the three markers increased (χ2 =6.584, P=0.01). The Median Survive Time of the patients with levels of the three markers decreased by more than 50%was longer than those with the levels decreased by less than 50% (χ2=5.418, P = 0.02). Conclusions The dynamic and combined detections of serum HMGB1, CEA, SCC in patients with esophageal squamous cell carcino-ma resection can effectively evaluate the therapeutic effect and prognosis.

Objective To evaluate the expression of bcl-2, p53, Ki-67 in malignant lymphoma (ML)and the relationship between the expression of bcl-2, Ki-67, p53 and prognosis for the patients who were given autologous hematopoietic stem cell transplantation (AHSCT). Methods The expression of bcl-2,Ki-67, p53 were measured by immunohistochemistry (IHC) on paraffin-embedded slices in 33 cases of ML who received AHSCT. Survival analysis was done by the Kaplan-Meier method and Log-Rank test.Multivariate analysis was carried out using COX proportional hazard model. Results For patients with ML who received AHSCT, the 3-year disease free survival (DFS) of bcl-2(+) group was 35.71%, while that bcl-2(-) group was 88.89 %. There was significant difference of DFS between the two groups. Meanwhile, for these patients, the 3-year DFS of Ki-67(+) and Ki-67(-) were 43.75 % and 85.71%, respectively (P ＜0.05).Multivariate analysis showed that the expression of bcl-2 and Ki-67 were the independent prognostic factors.Conclusion The expression of bcl-2 and Ki-67 were closely related with relapse after AHSCT in patients with ML. They were useful molecular makers for predicting the prognosis of patients with ML after AHSCT.

[Objective] To assess the predilection age,clinical features,treatment and pognostic factors of primary cutaneous B-cell lymphoma (PCBCL).[Methods] A total of 31 patients with PCBCL were registered in Tianjin Cancer Central Registry from January 1970 to September 2010,and 26 patients had complete medical recortds.A retrospective analysis was conducted on the 26 patients.The following indices were analyzed,including gender,age,body sites of initial involvement,extent of cutaneous involvement,pathological subtypes,metastatic sites,treatment,survival and prognosis.Data were processed with SPSS16.0 software,survival analysis was carried out by using Kaplan-Meier method,univariate analysis of prognostic factors by Log-rank test,multivariate analysis of prognostic faetors by COX proportional hazards model,and variables were selected by Forward LR method.[Results] Clinical manifestafions were atypical in these patients.The ratio of man and women was 1:1.6.Of the 26 cases,12 were primary cutaneous follicle-center lymphoma (PCFCL),8 were primary cutaneous marginal zone lymaphoma (PCMZL),and 4 were PCLBCL,leg type.Follow-up revealed lymph node involvement in 8 patients (4 in cervical nodes and 4 in inguinal nodes),distant metastasis of organs in 3 patients ( 1 in lung and pleura,1 in bone marrow and 1 in central nervous system).Most patients received surgical treatment combined with chemotherapy or chemoradiation.The 5-year overall survival rate was 80.8％(21/26).Statistical analysis showed that the prognosis of PCBCL was associated with histological subtype,lactate dehydrogenase (LDH) level and globulin level,but unrelated to gender,age,site of initial involvement,extent of cutaneous involvement,involvement of lymph nodes and organs,presence of B symptoms,treatment strategies,number of relapses,level of β2-globulin and hemoglobin,or lymphocyte absolute value.[Conclusion]s PCBCL,as a kind of rare extra-nodal lymphoma,usually occurs with atypical clinical mainfestations in persons aged from 39 to 66 years.The 5-year overall survival rate was 80.8％ in these patients.The prognosis of PCBCL seems to be related to histological subtypes,LDH and globulin levels.

Objective To study the clinical features, effects of therapeutic regimen and prognosis of patents with mantle cell lymphoma (MCL). Methods Clinical data of 27 MCL patients admitted in Tianjin Medical University Cancer Institute&Hospital from January 2008 to December 2014 were retrospectively analyzed. Cox regression analysis was used to analyze influencing factors of prognosis of MCL. Results The median age was 68 years old for 27 patients, and the male-to-female ratio was 4.4∶1. Ann Arbor staging showed that 25 cases were stageⅢ-Ⅳ(92.6%), 8 cases were heptosplenomegaly (29.6%), 7 cases showed extranodal involvement (25.9%). ECOG scoring showed that 4 cases with scores of 2-4 (14.8%), 8 cases were 0-3 (29.6%), 14 cases were 4-5 (51.9%) and 5 cases were 6-11 (18.5%). The Ki-67 index≤30%was found in 9 cases (33.3%), and>30%was found in 18 cases (67.7%). Patients with B symptom was found in 10 (37.0%). The elevated lactate dehydrogenase (LDH) was found in 17 cases (63.0%). The increased Beta 2- microglobulin was found in 8 cases (29.6%). Seven patients were found with bone marrow involvement. The total effective rate (ORR) was 81.8%in group with R-CHOP method, and the ORR was 68.8%in group with CHOP method. Multivariate analysis showed that age, LDH and Ki-67 were independent factors influencing the prognosis of MCL (P<0.05). Conclusion Most patients with MCL are found in advanced stage. Patients with age>60 years, elevated LDH and Ki-67 index>30%are with poor prognosis.

Objective: To study the relationship between the expressions of Bel -2, Ki -67, C -myc and prognosis in patients given chemotherapy for malignant lymphoma (ML). Methods: The expressions of Bel-2, Ki-67 and C-myc were measured by immunohistochemistry (IHC) in paraffin-embedded samples of 65 ML cases who received chemotherapy. The survival analysis was done by the Kaplan -Meier method and Log -rank test. Results: For patients with non -Hodgkin lymphoma (NHL) who received chemotherapy, the 3-year disease free survival (DFS) was 22.22% in Bcl-2(+) group compared with that of 55.56% in Bcl-2 (-) group. The difference of DFS was significant between the two groups. Meanwhile, for ML patients, the 3-year DFS was 37.50% in Ki-67(+) group, and 61.54% in Ki-67(-) group respectively(P < 0.05). Conclusion: The expressions of Bcl-2 and Ki-67 were closely related with relapse after chemotherapy in patients with ML. They were useful molecular makers for predicting the prognosis in patients with ML after chemotherapy.

Objective To investigate the clinical features and prognostic factors of primary thyroid lymphoma. Methods Records of 44 patients with pathologically confirmed primary thyroid lymphoma were reviewed. Detailed clinical and laboratory data were included in univariate analysis, and statistically significant factors in univariate analysis were then included in multivariate analysis.Results In univariate analysis, Ann Arbor stage, performance status, IPI, number of extra-lymphatic site, B symptoms, Hb, LDH and β_2-MG level, therapy model, histology type and tumor mass were found to be the prognostic factors associated with overall survival in primary thyroid lymphoma. In multivariate analysis, performance status, IPI, LDH, β_2-MG level, histology type, and tumor mass were independent prognostic factors of overall survival. Conclusion Performance status, IPI, LDH and β_2-MG level, histology type and tumor mass were demonstrated as independent prognostic factors of the overall survival in primary thyroid lymphoma.

Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a rare and distinct variant of DLBCL. It is classified as a unique subtype of DLBCL in the 2008 WHO classification of lymphomas. No standard and effective therapeutic regi-men is available for ALK+DLBCL because it shows a more aggressive clinical course and frequent relapse. Therefore, a standardized and individualized treatment is needed to benefit more patients diagnosed with ALK+DLBCL through a multiple disciplinary team. This arti-cle presents a case of an ALK+DLBCL patient who relapsed after transplantation and was successfully treated with the ALK kinase inhibi-tor Crizotinib.
