Ic期子宫内膜癌患者中MPA和EBRT的联合疗效

Objective: To report the comparative effect of combined medroxyprogesterone acetate (MPA) and external beam pelvic radiotherapy (EBRT) with EBRT alone on local or distant recurrences, overall survival and treatment related toxicities in patients with stage Ic grade 3 endometrial cancer. Methods: A retrospective review of 80 International Federation of Gyne-cology and Obstetrics (FIGO) stage Ic grade 3 endometrial carcinoma patients treated between October 1994 and October 2004 at Renmin Hospital, Wuhan University, China was performed. All patients underwent surgery, of which 40 patients in arm I received combined MPA and EBRT while in arm II 40 patients received only adjuvant EBRT after surgery. The median dose of EBRT in arm I was 50 Gy (range 36-54 Gy) and in arm II was 45.2 Gy (range 43.2-50.4 Gy). Multivariate analysis was performed for the prognostic factors and Kaplan-Meier method was used for overall survival. Results: Of the 80 eligible patients, 40 in each group could be evaluated. The follow-up times ranged from 4-98 months with a median of 45 months. The overall survival rates at five years were 73% among patients treated with combined MPA and EBRT and 28.2% among patients treated with EBRT alone (P < 0.001). The rate of distant metastasis was significantly higher among patients treated with EBRT alone group than combined MPA and EBRT (55% vs 25%, P = 0.006) while no difference in loco regional recur-rence rates was observed in both treatment groups. Most of the side effects observed in the combined MPA and EBRT group. Age (P < 0.001) and the presence of progesterone receptors (P = 0.003) were independent significant prognostic factors for overall survival in multiple regression analysis. Conclusion: We has been concluded that the addition of progestagen to external beam pelvic radiotherapy significantly improved survival and reduced distant metastasis among women with stage Ic grade 3 endometrial cancer.

Abstract：

Objective Nasopharyngeal carcinoma patients with stage N3 disease are prone to develop distant metastasis even treated with standard concurrent chemoradiotherapy(CRT).The aim of this study is to compare the ettlcacy of difierent chemotherapy sequences in these patients.Methotis All patients with histologically proven,carcinoma of the nasopharynx treated between July 1999 and November 2003 were restaged according to the AJCC 2002 stage classification system.A total of 114 patients had AJCC N3 diseases were analyzed retrospectively.Patients were treated by conventional RT technique using 6 MV photons or 60 Coγ-ray with 1.8-2.0 Gy per fraction,5 fractions a week,to a planned dose of 70 Gy.The prophylactic irradiation dose of the neck wss 54-60 Gy.Any positive lymph node was boosted to a total dose of 60-68 Gy.All patients received cisplatin-based chemotherapy of difierent sequences but 9 patients RT alone.CRT regimen was delivered in 37 patients,neoadjuvant chemotherapy(NACT)+CRT regimen in 53 patients and CRT+adjuvant chemotherapy(AC)regimen in 15 patients.Results The prophylactic irradiation dose of the neck wss 54-60 Gy.Any positive lymph node was boosted to a total dose of 60-68 Gy.All patients received cisplatin-based chemotherapy of difierent sequences but 9 patients received RT alone.CRT regimen was delivered in 37 patients,neoadjuvant chemotherapy(NACT)+CRT regimen in 53 patients and CRT+adjuvant chemotherapy(AC)regimen in 15 patients.Results The median follow up time was 54 months(3-117months).The 5-year overall survival rate was 59.1%in whole groups,and with 17%,51%,68%and 71%in RT,CRT,NACT+CRT and CRT+AC group,respectively(X2=15.44,P=0.001).The 5-year relapse-free survival rates were 83%,77%,88%and 93%in RT,CRT,NACT+CRT and CRT+AC group,respectively(X2=2.34,P=0.505).The 5-year metastasis-free survival rates were 17%,54%,72%and 80%in RT,CRT,NACT+CRT and CRT+AC group,respectively(X2=19.28,P=0.000).Conclusions The NACT+CRT and CRT+AC regimens were more effective than CRT alone for N3 disease in the current study.Large prospective,randomized clinieal studies are warranted.     

1030例早期乳腺癌术后放疗不同年龄组的预后分析

Objective To analyze the prognostic value of age in patients with early stage breast cancer. Methods The clinical characteristics of 1030 patients with early stage breast cancer (the number of positive axillary lymph nodes was less than 3) were retrospectively reviewed. Of all the patients, 468(stage Ⅰ, n = 227; and stage Ⅱ , n = 241) received breast conserving surgery (BCS) and 562 (stage Ⅰ, n =184; and stage Ⅱ, n= 378) received modified mastectomy. Patients were divided into young-age group (≤35,136 patients), middle-age group (> 35-≤60,738 patients) and old-age group (> 60,156 patients).The number of patients without postoperative radiation therapy after BCS is 16, 60 and 39 in the three groups, respectively. Two-dimensional conventional fractionated radiotherapy was administered. The prognostic value of the tumor size, status of axillary lymph nodes or hormonal receptors, postoperative radiation therapy were analyzed. Results The follow-up rate was 97.86%. Of 795 patients followed up more than 5 years, 110,569 and 116 patients were devided into the three groups, respectively. There were 40, 202 and 87 patients without radiation therapy in the three groups. The 5-year recurrence rates of the three groups were 6. 2%, 8. 7% and 10. 4% (χ2 = 1.14, P= 0.567). The 5-year distant metastasis rates were4.3% , 9.5 % and2. 5% (χ2 = 5.31 , P = 0. 070) . The5 - year survival rates were9l. 2% , 92. 6%and 82. 1% (χ2 = 6. 83, P = 0.033). The young-age group had more tumors smaller than 2. 0 cm (65.4%), less positive axillary lymph nodes (13.2%), poorer differential tumor and less positive hormone acceptors (48.0%). Of patients with tumor larger than 2. 0 cm who had no radiotherapy after BCS, the 5-year survival rates were 94%, 87% and 71% (χ2= 20.69, P= 0.000) in the three groups. The corresponding recurrence rates were 23%, 18% ,7%, (χ2 = 9. 97, P = 0. 007), and distant metastasis rates were23%, 25% and 10% (χ2 =8.51, P=0. 014). Conclusions The age is an important prognostic factor in patients with early stage breast cancer undergoing BCS, but not in those undergoing modified mastectomy.     

Elevated circulating levels of osteopontin are associated with metastasis in advanced non-small cell lung cancer

Objective:To investigate the relationship between postoperative metastasis and circulating levels of osteopontin in non-small cell lung cancer(NSCLC).Methods:The expression of osteopontin mRNA were detected with RT-PCR technique.The circulating levels of osteopontin were measured through ELASA in 46 NSCLC cases that had not been received any anti-cancer treatment at the time of sampling.The tissues from fifteen patients with benign pulmonary diseases were studied as control group.Results:The overall median mRNA expression level of osteopontin was approximately 70-fold higher in tumor tissues than in matched normal lung tissues(P<0.001).Over-expression of osteopontin mRNA was significantly associated with clinical stage(P=0.009).Advanced disease states had higher circulating level of osteopontin(stage I+II versus stage III+VI).In multivariate analysis,stage was the only independent factor influencing circulating levels of osteopontin.All patients were followed up for 12 months,2 of the 46 patients with both osteopontin mRNA expression and elevated plasma osteopontin levels had local recurrence and 10 had distant metastasis.There was a significant difference in the osteopontin levels between metastasis group and non-metastasis group.Conclusion:Preoperative plasma levels of osteopontin are significantly associated with post-operative metastasis in advanced NSCLC.

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.

】 ObjectiveTo research the influence of neck lymph nodes biopsy on the distant metastasis for NPC. MethodsThe data of 18 patents with NPC diagnosed by neck lymph nodes biopysy (group one) and of 69 patients with NPC diagnosed by nasopharyngeal biopsy (group two) in our hospital from January 1990 to december 1991 were collected χ² test was used to compare the rate of distant metastsasis in both groups. ResultsThe patients characteristics,iucluding age,staging and radiation dose were similar in both groups.The rate of distant metastasis was 55.6％ (10/18) in group one and 30.4％ (21/69) in group two,with significant difference between the two groups (P<0.05). ConclusionsThe neck lymph nodes biopsy can increase the rate of distant metastasis for NPC.     

晚期三阴性乳腺癌的临床特征及生存分析

Objective To characterize the sites of distant recurrence and clinical outcomes in a cohort of Chinese patients with metastatic triple-negative breast cancer (TNBC ). Methods One hundred and thirty-four patients with metastatic TNBC treated at Cancer Hospital of CAMS from January 1999 to December 2007 were included in this study. Hie clinicopathological features and long-term survival of the patients were retrospectively analyzed. Results The median age of the patients was 45 years. Most patients (72.7% ) had a higher predilection for visceral metastasis and early recurrence within the first two years of follow-up. Six patients (4.5%) presented with stage Ⅳ disease, 14 patients were diagnosed with locoregional recurrence after mastectomy, 75 patients with distant metastases, and 45 patients with both locoregional recurrence and distant metastasis. The most common site of first recurrence was the lung, and 62(51.7% )of the patients had more than two sites of metastasis. By July 30, 2009, 75 patients died of breast cancer (56.0%). The median overall survival (OS) was 26. 5 months [95% confidence interval (CI), 20. 5-32. 6 months]. The l-,3- and 5-year overall survivals ( OS) were 80. 9% ,37. 1% and 30.1% , respectively. The median overall survival time of 58 patients with single site of metastasis was 28.5 months, longer than that of patients with more than two sites of metastases. Patients whose initial distant recurrence was bone metastasis only (7 patients) had better prognosis, with a median OS of 84.2 months. The median OS (28.5 vs. 12.6 months, P =0.0001) differed significantly between patients who received first-line chemotherapy and those who did not. Forty-five of the 96 patients with measurable disease achieved complete/partial response (CR/PR), 39 patients had stable disease (SD), and 12 patients had disease progression (PD). The median OS was 36.1 months in patients with CR/PR, 20. 8 months with SD, and 14 months with PD, respectively. The median OS of patients with CR/PR was significantly longer than that of patients with SD/PD (P =0. 0106). Distant metastasis, first-line chemotherapy and clinical response were significantly related with OS by univariate analysis. Furthermore, first-line chemotherapy and the clinical response were demonstrated to be an independent prognostic factor by multivariate analysis. Conclusions Recurrence risk and mortality are considerably higher in TNBC patients within the early years of follow-up. TNBC patients have a higher risk of multiple and visceral metastases, and poorer survival, which might attribute to its aggressive clinical behavior and lack of effective regimens. Our findings also suggest that chemotherapy can effectively improve the clinical outcome of those patients.
