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.     

Retrospective analysis of results of treatment for nasopharyngeal carcinoma in Macao

Background： Nasopharyngeal carcinoma （NPC） is a common malignancy in Southeast Asia, however, a full consensus has not yet been reached as to the value of comprehensive treatment for NPC. This study was designed to evaluate the epidemiological characteristics of NPC and their prognostic value, as well as the long-term efficacy of NPC treatment. Patients and methods： A total of 248 patients, with different stages of NPC, were included in this study. Results： The 5-year overall survival （OS） rates for patients in stages I, II, lII and IV were 90.48%, 76.71%, 76.89% and 33.87%, respectively （P=0.000）, while the respective 5-year progression-free survival （PFS） rates were 85.15%, 72.36%, 63.88% and 26.26% （P=0.000）. The respective 5-year OS rates, according to stage, for the group that received radiotherapy combined with chemotherapy and for the group that received radiotherapy only were as follows： stages I and II, 81.67% and 79.59% （P=0.753）; stage III, 79.91% and 70.38% （P=0.143）; stage IV,, 35.22% and 0% （P=0.000）. The respective 5-year PFS rates in these groups were as follows： stages I and II, 75.83% and 74.98% （P=0.814）; stage III, 74.08% and 42.25% （P=0.027）; stage IV,, 27.31% and 0% （P=0.000）. Conclusions： Clinical staging appears to be the most important prognostic factor for NPC. As the stage number increases, both the 5-year OS and PFS significantly decrease. Adding chemotherapy to radiotherapy was not advantageous for patients with stage I or II NPC, however the addition of chemotherapy to radiotherapy significantly improved OS and PFS in patients with stage IV NPC. The addition of chemotherapy improved PFS, but not OS in patients with stage III NPC.     

A Prospective Randomized Study of Adjuvant Chemotherapy in Completely Resected Stage III-N2 Non Small Cell Lung Cancer

Objective: To evaluate the effect of postoperative adjuvant chemotherapy on survival after complete resection of stage III-N2 non-small-cell lung cancer. Methods: From Jan. 1999 to Dec. 2003, one-hundred and fifty patients, who were diagnosed as stage III-N2 non-small cell lung cancer after operation, were randomly devided into chemotherapy group and control group. The former received four cycles of chemotherapy with NVB (25 mg/m2, D1, D5)/paclitaxel (175 mg/m2, D1) and Carboplatin (AUC=5, D1). Results: In chemotherapy group, 75.8% (68/79) of patients had finished the 4 cycles of chemotherapy and no one died of toxic effects of chemotherapy. Twenty-five percent of the patients had grade 3?4 neutropenia and 2% had febrile neutropenia. The median survival for the entire 150 patients was 879 d, with 1-year survival rate of 81%, 2-year survival rate of 59% and 3-year survival rate of 43%. There was no significant difference in median survival between chemotherapy and control group (897 d vs 821 d, P=0.0527), but there was significant difference in the 1-year and 2-year overall survival (94.71%, 76.28% vs 512 d, P=0.122), but there was significant difference in the 2-year survival rate between two groups with brain metastases (66.7% vs 37.6% P<0.05). The median survival after brain metastasis appeared was 190 days. Conclusion: Postoperative adjuvant chemotherapy does not significantly improve median survival among patients with completely resected stage II-N2 non-small-cell lung cancer, but significantly improves the 1-year and 2-year overall survival. It neither decreases the incidence of brain metastasis but put off the time of brain metastasis.     

154例广泛期小细胞肺癌治疗结果预后因素分析

Objective To investigate independent prognostic factors for overall survival (OS) in extensive disease small cell lung cancer (EDSCLC). Methods Between January 2003 and December 2006, 154 patients diagnosed with extensive stage small cell lung cancer were enrolled in this study.Prognostic factors such as gender, age, performance status, smoking history, weight loss, distant metastasis, the number of matastasis, brain metastasis, the cycle of chemotherapy and thoracic radiation therapy (TRT) for EDSCLC patients were evaluated by univariate and multivariate analysis. Results The median following-up time was 40. 5 months. The rate of follow-up was 92. 2%. The MST and overall survival rates at 3-year in smoking group and no-smoking group were 13 months, 11.8% and 17 months,22. 8%,respectively (χ2=3.40,P =0. 064);in ChT/TRT group and ChT group, they were 17. 2 months, 17.9%and 9.3 months,13.9%, respectively(χ2=10.47,P=0.001);and in the cycle of chemotherapy ≥4 group and ＜ 4 group, they were 16 months, 20. 1% and 9.3 months, 2. 9%, respectively (χ2=17.79,P=0. 000). By multivariate analysis, smoking history was a statistically significant unfavorable factor for OS in EDSCLC patients (versus no-smoking, hazard ratio (HR)=1.462, χ2=4.40, P=0.036). In addition, ≥4 cycles of chemotherapy and TRT were favorable prognostic factors ( ≥4 cycles vs ＜4 cycles, HR =0. 420,χ2 = 17. 17, P = 0. 000; ChT/TRT vs ChT, HR = 0. 634, χ2 = 6. 20, P = 0. 013). Conclusions Smoking is a independent unfavorable prognostic factor and ≥ 4 cycles of chemotherapy And TRT are independent favorable prognostic factors for OS in EDSCLC.

Abstract：

Objective To retrospectively analyze the treatment results and prognostic factors in patients with primary bone lymphomas (PBL).Methods Thirty-one patients with PBL treated between April 1994 and May 2009 at Sun Yat-sen University Cancer Center were analyzed.All patients were diagnosed by pathology.Twenty-two patients had stage Ⅰ E, 4 patients had stage Ⅱ E and 5 patients had stage ⅣE diseases.One patient was treated with surgical resection alone, 1 patient with radiotherapy (RT) alone, 2 patients with chemotherapy (CT) alone and 4 patients with resection followed by chemotherapy.The remaining 23 patients received CT combined with RT.The median radiation dose was 50 Gy.Results The median follow-up time was 45.2 months.The follow-up rate was 83.9%.Nine patients had a follow-up time of 10 years.The 5-year and 10-year overall survival rates were 92% and 92%, respectively.The 5-year and 10-year disease-free survival rates were 79% and 70%, respectively.In the group who received non-combined chemoradiotherapy, the complete response rate was 50%, the incidence of progression or recurrence was 2/8 and the median recurrence time was 6.8 months.In the group who received combined chemoradiotherapy, the complete response rate was 65%, the incidence of progression or recurrence was 13% and the median recurrence time was 39.1 months.In univariate analyses, favorable prognostic factors for survival included age≤50 years (χ2=5.32,P=0.021) and ECOG PS score 0-1(χ2=5.48,P=0.019).Favorable prognostic factors for DFS included IPI score≤1(χ2=7.81,P=0.005) and ECOG PS score 0-1(χ2=18.70,P=0.000).Conclusions Treatment results of patients with PBL can be generally well.CT combined with RT appears to be the treatment of choice.RT dose ≥40 Gy is safe and feasible.Younger age and better performance status are associated with a better outcome.     

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.     

Preoperative Chemoradiotherapy for Inflammatory Breast Cancer

OBJECTIVE To observe the effect of preoperative chemoradiotherapy for inflammatory breast cancer. METHODS From December 1996 to December 2000, we received and treated 21 patients with inflammatory breast carcinoma with a combined-modality treatment. The chemotherapy protocol consisted of cyclophos-phamide (CTX), pirarubicin (THP-ADM) and 5-fluorouracil (5-FU) or CTX, 5-Fu and methotrexate (MTX). The same infusion scheme was repeated on day 21. After 3-4 cycles the patients were treated with radiotherapy. When the radiation dose reached 40 Gy, the patients who were unable or unwilling to under go an operation received continued radiotherapy. When the radiation dose to the supra clavicular fossa and internal mammary lymph nodes reached 60 Gy and 50 Gy respectively, the radiotherapy was stopped. Chemotherapy was then continued with the original scheme. Patients who had indications for surgery and were willing to under go an operation received no treatment for 2 weeks, after which a total mastectomy was performed. Chemotherapy and radiotherapy was resumed with the original scheme after the operations. When the radiation dose reached 50 Gy, radiotherapy was stopped. RESULTS All patients were followed-up for more than 5 years with a follow-up rate of 100%. The overall 3 and 5-year survival rates of these patients were 42.9%, and 23.8% respectively. For patients in Stage IIIB the 3 and 5-year survival rates were 50.0% and 27.8% respectively, and for patients in Stage IV, the 3 and 5-year survival rates were both 0.0%. There was a significant difference between the 2 stage groups (P<0.05, x2=11.60). For patients who received an operation, the 3 and 5-year survival rates were 80.0% and 33.3% respectively, For patients who were not treated with an operation, the 3 and 5 -year survival rates were both 0.0%, There was a significant difference between the operated and non-operated groups (P<0.05, x2=11.64). CONCLUSION The prognosis of inflammatory breast carcinoma is poor. Before operation, a combined -modality treatment (first chemotherapy, then local therapy, finally chemotherapy and radiotherapy) is the best treatment method.

目的 探讨Ⅰ_E~Ⅱ_E期原发鼻腔与原发韦氏环NK/T细胞淋巴瘤在临床特征和预后等方面的差别。方法 回顾分析1991-2011年本院初治的273例患者,其中Ⅰ_E期184例,Ⅱ_E期89例。原发鼻腔(NC-NKTL)209例和原发韦氏环(WR-NKTL)64例。258例(94.5%)患者先接受化疗,多数患者接受CHOP或类似方案化疗,放疗中位剂量为54 Gy。结果 与NC-NKTL相比,WR-NKTL中Ⅱ_E期和有B症状者显著增多。两组治疗后有效率相近(88.7%和87.9%,P=0.869)。随访率96.3%,随访时间满5年者196例。5年总生存率(OS)和无进展生存率(PFS)分别为52.6%和41.4%,其中NC-NKTL的5年OS有高于WR-NKTL的趋势(57.0%∶39.0%,P=0.062),而5年PFS则高于WR-NKTL的(46.7%∶25.8%,P=0.019)。结论 早期原发韦氏环NK/T细胞淋巴瘤较原发鼻腔病变更易发生全身症状和颈部淋巴结转移,预后较差,临床上考虑提早放疗和颈部淋巴结预防照射。     

结外鼻型NK/T细胞淋巴瘤27例临床分析

 目的　分析结外鼻型NK／T细胞淋巴瘤（ENKL）的临床特征、不同治疗方法的疗效及影响预后的因素。方法　回顾性分析27例ENKL患者,予单纯放疗3例,单纯化疗9例,其余15例采用放化疗联合治疗,其中3例患者行自体造血干细胞移植（auto-HSCT）。对B组症状、乳酸脱氢酶（LDH）、一般状况评分、国际预后指数评分、Ann Arbor分期、治疗模式和近期疗效进行单因素分析。单因素分析采用 Kaplan-Meier法。结果　全组平均生存时间为32（2～42）个月。1、2、3年的总体生存（OS）率分别为79.5 %、71.6 %、53.7 %。早期（Ⅰ期+Ⅱ期）及晚期（Ⅲ期+Ⅳ期）患者2年生存率分别为83.3 %、62.3 %（P＝0.368）,早期患者单纯放疗或化疗4例均获总有效（OR）（CR+PR）,化疗联合放疗10例,OR 9例。晚期患者单纯化疗8例,OR 2例;化疗联合放疗5例,OR 2例。单因素分析显示,年龄及近期疗效是影响生存率的主要因素（P＜0.05）。结论　对于ENKL早期患者,放疗或化疗可取得较好的疗效,放化疗联合治疗及auto-HSCT是治疗晚期ENKL的重要方法。年龄及近期疗效可作为判断ENKL预后的参考因素。
