LRP5 polymorphism-A potential predictor of the clinical outcome in advanced gastric cancer patients treated with EOF regimen

Purpose： Wnt pathways control key biological processes that potentially impact on tumor progression and patient survival. The present study analyzed the polymorphism of lipoprotein-related receptor 5 （LRPS） （gene with key functions in Wnt signaling） and its impact on the response to chemotherapy and survival of patients with advanced gastric cancer （AGC）. Methods： A total of 107 consecutive patients with AGC treated with first-line chemotherapy of EOF regimen were enrolled in the present retrospective study. The association between single nucleotide polymorphism （SNP） of rs3736228 in LRP5 and the clinical outcomes of the patients was studied. Results： The CC genotype of rs3736228 was significantly correlated with a higher disease control rate when compared to the CT and TT genotypes （89.3% and 61.8%, respectively, P〈0.001）. A univariate survival analysis also showed that the progression free survival （PFS） and overall survival （OS） for the patients with the TC and TF genotypes of rs3736228 were worse than for the patients with the CC genotype （PFS： 3.3 and 6.7 months, respectively, HR =0.454, P〈0.001; OS： 8.1 months and 18.8 months, respectively, HR =3.056, P〈0.001）. A multivariate Cox model incorporates rs3736228 and clinical features, also identified rs3736228 was significantly associated with the PFS and OS. Conclusions： Our results firstly highlight the importance of LRPY gene of Wnt pathway in the treatment of AGC and identify polymorphism of rs3736228 as independent predictor of disease control rate, PFS and OS in AGC patients treated with first-line chemotherapy of EOF regimen in the Chinese Han population.     

白细胞介素-18基因607和137多态性在前列腺癌临床特性的影响(英文)

Objective: The aim of this study was to determine whether the presence of IL-18 polymorphisms -137 G/C and -607 A/C was associated with grade, clinical stage, and survival in patients with prostate cancer. Methods: The study cohort included 126 patients with prostate cancer. Control group consisted of 125 samples from Chinese population. Genomic DNA was extracted from EDTA-anticoagulated peripheral blood leukocytes by the salting-out method. The genotyping of the two IL-18 polymorphisms was performed using predesigned TaqMan SNP Genotyping Assays. Results: The studied IL-18 gene polymorphisms did not influence susceptibility to prostate cancer in the analyzed group of patients (IL-18-607, P = 0.342; IL-18-137 P = 0.715) but may contribute to disease onset and aggressiveness. IL-18-607 CC genotype was significantly associated with higher tumor grade (P = 0.025) and stage (P = 0.001). IL-18-137 GG genotype was correlated with higher tumor grade (P = 0.018) and stage (P = 0.007). The Cox proportional hazard model showed that tuumor grade and stage grouping were independent prognostic factors but IL-18 polymorphism was not. Polymorphism variants in the IL-18 gene (IL-18-607 and IL-18-137) may be associated with a worse prognosis for prostate cancer. Conclusion: High levels of IL-18 production may play a major role in the growth, invasion and metastasis of prostate cancer.     

三维放疗联合顺铂同期化疗局部晚期宫颈癌疗效分析

Objective To analyze the therapeutic efficacy and treatment related toxicities for patients with locally advanced cervical cancer treated with three-dimensional conformal radiotherapy (3DCRT) combined with concurrent chemotherapy. Methods From January 2007 to February 2008, 181 patients with stage ⅡA-ⅣA cervical cancer were retrospectively analyzed. All patients were treated with CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent weekly cisplatin-based chemotherapy. The median age was 50 years (range, 32 to 82 years). The overall survival ( OS), disease-free survival (DFS) and local control (LC) rates were calcalated by Kaplan-Meier method and the difference was compared using Log-rank test. The treatment related toxicities were evaluated according to Radiotherapy Oncology Group (RTOG) criteria. Results With a median follow-up time of 34 months and following rate of 92. 2%, the 3-year OS, DFS and LC rates were 73.4%, 70. 4% and 91.3%,respectively. The 3-year OS rate was 66. 9% for patients with tumor diameter ≥4 cm and 86. 4% for those with tumor diameter ＜4 cm( χ2 =6. 29 ,P =0. 012). The incidences of grade 1 and grade 2 acute toxicities of the lower gastrointestinal tract and the genitourinary system were 40. 0% ,45.0% and 19. 9% ,4. 4%,retrospectively. There were no grade 3 or more acute toxicities. The incidence of grades 3 or 4 late toxicities of the lower gastrointestinal tract was 4. 9%. Conclusions CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent chemotherapy can achieve good therapeutic effects for locally advanced cervical cancer. The acute and late toxicities are significantly reduced compared with historic controls as a result of incorporation of 3DCRT technique.     

Effects of postmastectomy radiotherapy on prognosis in different tumor stages of breast cancer patients with positive axillary lymph nodes

Objective： To explore the effects of postmastectomy radiotherapy（PMRT） on the locoregional failure-free survival（LRFFS） and overall survival（OS） of breast cancer patients under different tumor stages and with one to three positive axillary lymph nodes（ALNs）. Methods： We conducted a retrospective review of 527 patients with one to three positive lymph nodes who underwent modified radical or partial mastectomy and axillary dissection from January 2000 to December 2002. The patients were divided into the T1-T2 N1 and T3-T4 N1 groups. The effects of PMRT on the LRFFS and OS of these two patient groups were analyzed using SPSS 19.0, Pearson＇s χ2-test, Kaplan-Meier method, and Cox proportional hazard model. Results： For T1-T2 N1 patients, no statistical significance was observed in the effects of PMRT on LRFFS [hazard ratio（HR）=0.726; 95% confidence interval（CI）： 0.233-2.265; P=0.582] and OS（HR=0.914; 95% CI： 0.478-1.745; P=0.784） of the general patients. Extracapsular extension（ECE） and high histological grade were the risk factors for LRFFS and OS with statistical significance in multivariate analysis. Stratification analysis showed that PMRT statistically improved the clinical outcomes in high-risk patients [ECE（＋）, LRFFS： P=0.026, OS： P=0.007; histological grade III, LRFFS： P〈0.001, OS： P=0.007] but not in low-risk patients [ECE（–）, LRFFS： P=0.987, OS： P=0.502; histological grade I-II, LRFFS： P=0.816, OS： P=0.296]. For T3-T4 N1 patients, PMRT effectively improved the local control（HR=0.089; 95% CI： 0.210-0.378; P=0.001） of the general patients, whereas no statistical effect was observed on OS（HR=1.251; 95% CI： 0.597-2.622; P=0.552）. Absence of estrogen receptors and progesterone receptors（ER/PR）（–） was an independent risk factor. Further stratification analysis indicated a statistical difference in LRFFS and OS between the high-risk patients with ER/PR（–） receiving PMRT and not receiving PMRT [ER/PR（–）, LRFF     

白血病患者造血干细胞移植前单次全身照射的预后分析

Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.     

早期鼻腔NK/T细胞淋巴瘤治疗方法和预后分析

Objective To investigate the prognosis of patients with nasal NK/T cell lymphoma receiving different treatment modalities. Methods From 1990 to 2004, 85 patients with stage ⅠE and ⅡE primary nasal NK/T cell lymphomas were retrospectively studied. Twenty patients received chemotherapy of CHOP regimen alone, 11 patients received radiotherapy only, 6 patients received radiotherapy followed by more than 2 cycles of chemotherapy, and 48 patients received more than 2 cycles of chemotherapy followed by radiotherapy. Survival analysis was performed by the Kaplan-Meier method, the difference between groups was evaluated by the Log-rank test, and the Cox regression model was used for multivariate analysis. Results The 5-year overall survival rate (OS) was 40%. The 5-year OS was 57% and 28% for limited stage ⅠE and extended stage ⅠE(X2 =8. 87, P =0. 003), and 23% for stage ⅡE, which was similar to extended stage ⅠE (X2 =0. 19, P-0. 664). The 5-year OS was 13%, 54% and 47% for chemotherapy alone, radiotherapy followed with or without chemotherapy, and chemotherapy followed by radiotherapy, respectively. The last two groups had better OS than chemotherapy alone (P = 0. 030 and 0.049). The 5-year OS was 58% and 12% for patients achieving complete response (CR) and uncomplete response (X2 = 30.68, P = 0. 000).The CR rate was 56% and 86% for radiotherapy of ≤50 Gy and >50 Gy (X2 =6.11, P=0. 013). The corresponding 5-year relapse-free survival rate was 89% and 84% (X2 =0.36, P=0.551). Of 68 patients receiving initial chemotherapy, the CR rate of those who received ≤2, 3-4 and ≥5 cycles was 0, 20%and 3 3 % , respectively (X2 = 7.65 , P = 0. 022) . For 5 0 patients who received ≥ 3 cycles of initial chemotherapy and 17 patients who received initial radiotherapy of ≥40 Gy, the CR rate was 28% and 88%(χ2= 18. 75, P= 0. 000). In patients with pathological nodular and ulcer type, the CR rates with radiotherapy were higher than with chemotherapy (100%: 38%, χ2 = 7.92, P = 0. 005; and 100%: 11%,χ2 = 14.40, P = 0. 000). Multivariate analysis showed that stage and recent effect were the independent prognostic factors. Conclusions The initial radiotherapy with 50 Gy is appropriate for early stage nasal NK/T cell lymphomas. Combined chemotherapy could be used for extended stage ⅠE and ⅡE, but the outcome of CHOP regimen is poor.     

Analysis of recurrence for locally advanced gastric or gastroesophageal cancer patients after receiving curative gastrectomy ( ＞ D1 ) and its indication for adjuvant chemoradiotherapy

Objective The benefit of adjuvant chemoradiotherapy remains controversial for gastric cancer patients treated with more than D1 dissection. This retrospective analysis is to distinguish the first site of recurrence in patients treated with curative resection and more than D1 dissection and to find any feasible adjuvant concurrent chemoradiotherapy recommendation for them. Methods All patients treated between January 2002 and December 2004 who met the following criteria were analyzed: primary gastric or gastroesophageal cancer, underwent curative gastrectomy ( UICC R0 ) and more than D1 lymphadenectomy,pathologically staged as T3-4N0-1 M0, or any Tx N2-3M0. There were 297 patients analyzed and 19.5%,52. 2%, 17. 8% , 10. 4% of patients had stage Ⅱ ( T3 N0 M0, T1 N2 M0 ), Ⅲa, Ⅲb and Ⅳ ( M0 ) diseases,respectively. 76. 1% of patients received adjuvant chemotherapy, while Only 2 patients underwent adjuvant radiotherapy. Failure patterns and the prognostic factors for locoregional recurrence were analyzed. Results The median follow-up time was 61 months and the follow-up rate was 92. 3%. 145 patients developed recurrence with a median recurrent time of 26 months. Locoregional recurrence was observed in 82 patients and distant metastasis in 79 patients. Gastric stump, anastomosis, intra-abdominal lymph nodes were the most common sites of locoregional recurrence. Liver and lung were the most frequent sites of distant metastasis. Prognostic variables for locoregional recurrence were identified after univariate analysis,including pathologic type ( χ2 = 11.50, P = 0. 009 ), total number of dissected lymph nodes ( χ2 = 6. 65,P =0. 010), the number of positive lymph node ( χ2 =5. 80,P =0. 016), lymph node capsular invasion ( χ2 =pathologic type, total number of dissected lymph nodes, lymph node capsular invation, AJCC TNM stage and Borrmann type were independent prognostic factors for locoregional recurrence ( χ2 = 6. 77,19. 33,17. 84 and 6. 02,P =0. 009,0. 000,0. 000 and 0. 014). Conclusions Locoregional recurrence remains the main cause of failure for locally advanced gastric or gastroesophageal cancer patients even though the patients have had more than D1 lymphadenectomy. The role of adjuvant concurrent hemoradiotheray for those patients is warranted.

The cardiotoxicity and long-term efficacy of different doses of epirubicin in the adjuvant treatment of breast cancer patients：A case control study

Abstract Objective： The aim of the study was to observe the cardiac toxicity caused by different doses of epirubicin in the adjuvant treatment of breast cancer and to evaluate the long-term efficacy. Methods： The 180 cases of breast cancer patients received epirubicin based adjuvant chemotherapy. The patients were randomly assigned to high-dosage group （90 rag/m^2）, medium-dosage group （70 mg/m^2） and low-dosage group （50 rag/m^2）, the primary endpoint was cardiac toxicity. The secondary outcomes were the 5-year overall survival （OS） and 5-year disease-free survival （DFS）. Results： During chemo- therapy, the clinical symptoms such as palpitation, dyspnea and paroxysmal nocturnal dyspnea occurred in 6 patients with the high-dosage group, 4 patients with the medium-dosage group and 3 patients with the low-dosage group. The number of patients who had changed in electrocardiogram （ECG） was 7, 5 and 4 in three groups, respectively. The echocardiographic showed each group had only one case with LVEF 〈 50%, there was no significantly difference （P 〉 0.05）. In the three groups, the 5-year DFS rates were 73.3% （44/60） in high-dose group, 53.3% （32/60） in medium-dose group and 41.6% （25/60） in low dose group. The 5-year OS rates were 85.0% （51/60）, 68.3% （41/60） and 58.3% （35/60） in three groups, respectively. The differences were statistically significant （P 〈 0.05）. Conclusion： The high-dose epirubicin in adjuvant chemotherapy with CEF （cyclophosphamide, epirubicin and fluorouracil） regimen could improve the 5-year OS rate and 5-year DFS rate on patients of breast cancer. The cardiotoxicity was mild-moderate and well tolerated.
