国际预后分数预测晚期霍奇金淋巴瘤预后的可行性研究

背景与目的:目前,按标准方案治疗晚期霍奇金淋巴瘤(HodgkinNslymphoma,HL)治愈率可达60%。晚期HL国际预后因素课题组研究总结出晚期初治HL的7个不良预后因素:男性、年龄≥45岁、Ⅳ期、白细胞增高、淋巴细胞减少、低血红蛋白、低白蛋白,并据此提出了国际预后分数(internationalprognosticscore,IPS)的概念。本研究旨在探索应用IPS预测晚期HL预后的价值。方法:回顾性分析1980年1月至2004年12月中山大学肿瘤防治中心初次治疗的141例晚期HL,按照确诊时患者不良预后因素的数目计算IPS。采用Kaplan-Meier法进行生存分析,生存率的比较用log-rank检验,采用Cox部分风险模型进行多因素分析,按IPS分组计算生存率并进行生存率比较。结果:141例晚期HL患者5年无失败生存率(failurefreesurvival,FFS)为57.6%,5年总生存率(overallsurvival,OS)为68.1%。IPS=0～1、2、3和IPS≥4组的5年FFS分别为67.7%、63.2%、61.8%、34.9%;5年OS分别为81.0%、75.5%、70.3%、42.3%。低危患者(IPS0～2)和高危患者(IPS≥3)5年FFS分别为65.4%和48.9%(P=0.012);5年OS分别为78.4%和57.1%(P=0.004)。接受ABVD方案[阿霉素(A)、博来霉素(B)、长春花碱(V)、氮烯咪胺(D)]或MOPP方案[氮芥(M)、长春新碱(O)、甲基苄肼(P)、强的松(P)]治疗的低危患者的5年OS均优于高危患者;接受ABVD治疗的高危晚期HL患者5年FFS和OS均显著优于接受MOPP方案治疗者。多因素分析显示B症状、结外病变、接受MOPP方案化疗为晚期HLFFS和OS独立预后不良因素。结论:IPS对晚期HL的预后有较好的预测价值;高危晚期HL患者接受MOPP方案化疗生存比接受ABVD方案差,推荐接受ABVD方案或更强的方案化疗。     

Consolidation radiation after complete remission in Hodgkin's disease following six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy: is there a need?

PURPOSE: Combined modality treatment using multidrug chemotherapy (CTh) and radiotherapy (RT) is currently considered the standard of care in early stage Hodgkin's disease. Its role in advanced stages, however, continues to be debated. This study was aimed at evaluating the role of consolidation radiation in patients achieving a complete remission after six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy using event-free survival (EFS) and overall survival (OS) as primary end points. PATIENTS AND METHODS: Two hundred and fifty-one patients with Hodgkin's disease attending the lymphoma clinic at the Tata Memorial Hospital (Mumbai, India) from 1993 to 1996 received induction chemotherapy with six cycles of ABVD after initial staging evaluation. A total of 179 of 251 patients (71%) achieved a complete remission after six cycles of ABVD chemotherapy and constituted the randomized population. Patients were randomly assigned to receive either consolidation radiation or no further therapy. RESULTS: With a median follow-up of 63 months, the 8-year EFS and OS in the CTh-alone arm were 76% and 89%, respectively, as compared with 88% and 100% in the CTh+RT arm (P =.01; P =.002). Addition of RT improved EFS and OS in patients with age < 15 years (P =.02; P =.04), B symptoms (P =.03; P =.006), advanced stage (P =.03; P =.006), and bulky disease (P =.04; P =.19). CONCLUSION: Our study suggests that the addition of consolidation radiation helps improve the EFS and OS in patients achieving a complete remission after six cycles of ABVD chemotherapy, particularly in the younger age group and in patients with B symptoms and bulky and advanced disease.     

Comparison of ABVD and alternating or hybrid multidrug regimens for the treatment of advanced Hodgkin's lymphoma: results of the United Kingdom Lymphoma Group LY09 Trial (ISRCTN97144519).

PURPOSE: To perform an open-label, randomized, controlled trial comparing treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with two multidrug regimens (MDRs) for advanced Hodgkin's lymphoma (HL). PATIENTS AND METHODS: Eight hundred seven patients with advanced HL (stage III to IV, or earlier stage with systemic symptoms or bulky disease) were randomly assigned between ABVD and MDR specified before randomization as alternating chlorambucil, vinblastine, procarbazine, and prednisolone (ChlVPP) with prednisolone, doxorubicin, bleomycin, vincristine, and etoposide (PABIOE), or hybrid ChlVPP/etoposide, vincristine, and doxorubicin (EVA). Radiotherapy was planned for incomplete response or initial bulk disease. RESULTS: At 52 months median follow-up, 212 event-free survival (EFS) events (disease progression or any death) were reported. In the primary comparison, at 3 years EFS was 75% (95% CI, 71% to 79%) for ABVD and 75% (95% CI, 70% to 79%) for MDRs (hazard ratio [HR] = 1.05; 95% CI, 0.8 to 1.37; HR more than 1.0 favors ABVD). The 3-year overall survival (OS) rates were 90% (95% CI, 87% to 93%) in patients allocated ABVD and 88% (95% CI, 84% to 91%) in patients allocated MDRs (HR = 1.22; 95% CI, 0.84 to 1.77). Patients receiving MDRs experienced more grade 3/4 infection, mucositis, and neuropathy. One occurrence of myelodysplastic syndrome was reported, but no acute leukemia was reported. When the two MDRs are compared separately with ABVD, neither the alternating nor the hybrid regimen showed a statistically significant difference from ABVD for EFS or OS. Subgroup analysis suggested that MDRs may be associated with poorer outcomes in older patients (heterogeneity test of OS older or younger than 45 years, P = .020). CONCLUSION: There was no evidence of significant difference in EFS or OS between ABVD and MDRs in the trial overall or if the two MDR versus ABVD comparisons are considered separately. ABVD remains the standard for treatment of advanced HL.     

Therapy of Hodgkin's lymphoma in clinical practice: A retrospective long-term follow-up analysis

Treatment of Hodgkin's lymphoma (HL) is perceived to be relatively straightforward. Consequently, patients are not usually referred to hemato-oncologically specialized centres and are treated locally instead. Comprehensive findings beyond prospective controlled trials are therefore lacking. Clinical data of 209 patients who had received a HL diagnosis were collected. A total of 7 patients received radiotherapy (RT) alone (3%), 75 (35%) were treated with a combination of chemotherapy (CT) and RT and 127 patients received CT alone [mainly doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD)]. Complete response (CR) following first-line treatment was achieved in 178 patients (85%) and in 195 (93%) after salvage treatment. Favorable disease (p=0.000359), limited-stage disease (p=0.0003), involvement of lymph nodes above the diaphragm (p=0.05) and absence of mediastinal bulky tumor involvement positively affected the CR rate following first-line treatment. Out of the 195 patients that achieved CR, 31 relapsed. Male gender (p=0.043) and age over 45 years (p=0.047) were significantly associated with an increased incidence of relapse. Age at diagnosis was the key factor affecting long-term outcome. The event-free survival (EFS) projected at 120 months was 80 and 57% for patients younger and older than 45 years, respectively (p=0.022). The overall survival (OS) projected at 120 months was 92 and 38% for patients younger and older than 45 years, respectively (p=0.00561). A second neoplasia was diagnosed in 8 patients. The development of a tumor in 4 cases (breast, lung and thyroid cancer) was likely RT-related. Only 1 patient not receiving RT developed acute myeloid leukemia. The EFS and OS of the 141 early-stage patients treated with CT + RT (n=62) or with CT alone (n=79) were not statistically different.     

Combination chemotherapy plus low-dose involved-field radiotherapy for early clinical stage Hodgkin's lymphoma

PURPOSE: To present our long-term experience regarding the use of chemotherapy plus low-dose involved-field radiotherapy (IFRT) for clinical Stage I-IIA Hodgkin's lymphoma. METHODS AND MATERIALS: We analyzed the data of 368 patients. Of these, 66 received mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and 302 received doxorubicin (or epirubicin), bleomycin, vinblastine, and dacarbazine [A(E)BVD]. Patients with complete remission or very good partial remission were scheduled for low-dose IFRT (< or =3200 cGy). RESULTS: The 10-year failure-free survival (FFS) and overall survival (OS) rate was 85% and 86%, respectively. A(E)BVD-treated patients had superior 10-year FFS and OS rates compared with MOPP-treated patients (87% vs. 75%, p = 0.009; and 93% vs. 71%, p = 0.0004, respectively). Only 10 of 41 relapses had any infield (irradiated) component. Of the complete responders/very good partial responders treated with low-dose IFRT, those who received <2800 cGy had inferior FFS but similar OS as those who received 2800-3200 cGy. Adverse prognostic factors for FFS included age > or =45 years, leukocytosis > or =10 x 10(9)/L, and extranodal extension. Secondary acute leukemia developed after MOPP with or without salvage therapy (n = 6) or after ABVD plus salvage therapy (n = 2). None of the nine secondary solid tumors developed within the RT fields. CONCLUSION: IFRT at a dose of 2800-3000 cGy is highly effective in clinical Stage I-IIA HL patients who achieved a complete response or very good partial response with A(E)BVD. The long-term toxicity with respect to secondary malignancies appears to be acceptable.     

Efficacy and Safety of First Line Vincristine with Doxorubicin,Bleomycin and Dacarbazine (ABOD) for Hodgkin’s Lymphoma: a Single Institute Experience

Background: ABVD (doxorubicin, bleomycin, vinblastine (Vb) and dacarbazine) is the standard regimen inHodgkin’s lymphoma (HL).Vincristine (O) is a mitotic spindle agent like Vb. We aimed to evaluate the efficacyand safety of O as a part of ABOD in HL. Materials and Methods: Patients who had ABOD were enrolled. StageI-II HL were evaluated for unfavorable risk factors according to NCCN. National Cancer Institute CommonToxicity Criteria was used for toxicity. Results: Seventy-nine HL patients in our center between 2003 and 2007were evaluated retrospectively. Median follow-up was 54 months. Most of the patients were male in their thirddecade. Median ABOD cycles were 6 (2-8). Primary refractory disease rate was 17.7% whereas it was 5.1% forearly relapse and 5.1% for late relapse disease. Response rates were as 82.3% for complete response, 11.4%for partial response, 5.1% for stable disease and 1.3% for progressive disease. Half of relapsed patients hadautologous stem cell transplantation. Estimated 5-year failure-free survival was 71% and significantly longerin early stage patients without risk factors, bulky disease or radiotherapy (RT) (p=0.05, p<0.0001, p=0.02;respectively). Estimated 5-year overall survival was 74% and significantly longer in those who had no RT(p=0.001). Dose modification rate was 5.1% and chemotherapy delay rate was 19%. There were no toxicityrelateddeaths. Conclusions: ABOD seems to be effective with managable toxicity in HL, even in those with poorprognostic factors.     

ABVD plus radiotherapy versus EVE plus radiotherapy in unfavorable stage IA and IIA Hodgkin's lymphoma: results from an Intergruppo Italiano Linfomi randomized study.

BACKGROUND: In 1997, the Intergruppo Italiano Linfomi started a randomized trial to evaluate, in unfavorable stage IA and IIA Hodgkin's lymphoma (HL) patients, the efficacy and toxicity of the low toxic epirubicin, vinblastine and etoposide (EVE) regimen followed by involved field radiotherapy in comparison to the gold standard doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) regimen followed by the same radiotherapy program. PATIENTS AND METHODS: Patients should be younger than 65 years with unfavorable stage IA and IIA HL (i.e. stage IA or IIA with bulky disease and/or subdiaphragmatic disease, erythrocyte sedimentation rate higher than 40, extranodal (E) involvement, hilar involvement and more than three involved lymph node areas). RESULTS: Ninety-two patients were allocated to the ABVD arm and 89 to the EVE arm. Complete remission (CR) rates at the end of treatment program [chemotherapy (CT) + RT] were 93% and 92% for ABVD and EVE arms, respectively (P = NS). The 5-year relapse-free survival (RFS) rate was 95% for ABVD and 78% for EVE (P < 0.05). As a consequence of the different relapse rate, the 5-year failure-free survival (FFS) rate was significantly better for ABVD (90%) than for EVE (73%) arm (P < 0.05). No differences in terms of overall survival (OS) were observed for the two study arms. CONCLUSIONS: In unfavorable stage IA and IIA HL patients, no differences were observed between ABVD and EVE arms in terms of CR rate and OS. EVE CT, however, was significantly worse than ABVD in terms of RFS and FFS and cannot be recommended as initial treatment for HL.     

Primary refractory and relapsed Hodgkin lymphoma with unfavorable prognosis

In this retrospective clinical study 100 patients with primary unfavorable prognosis stage II Hodgkin lymphoma (HL) (n = 50) or stage IV HL (n = 50). The ABVD chemotherapy allowed to achieve remission in 90% of cases with 5-year relapse-free survival (RFS) and overall survival (OS) of 64% and 92%, the basic BEACOPP regimen lead to the same 90% remission rate with 74% DFS and 94% OS. These results for ABVD and basic BEACOPP regimens are characterized by similar statistic values (p = 1.0; p = 0.6; p = 0.9), although the use basic BEACOPP lead to statically valid decrease of grade III-IV toxicity (p = 0.005). The occurrence of primary refractory HL was slightly higher in basic BEACOPP group (18% versus 10% in ABVD group), although this difference had no statistical value (p = 0.3) and was probably due to higher number of patients with > 1 extranodal localizations. The occurrence of primary refractory HL correlated to disease stage: 6% in stage II and 22% in stage IV (p = 0.04). HL relapse frequency in ABVD and BEACOPP groups was similar (12% and 8%), there was no statistically valid difference (p = 0.5). In ABVD and basic BEACOPP recipients with stage II/IV HL the primary refractory disease rate was 15%, relapse rate was 10%. Five-year OS in primary refractory and relapsed patients was lower, than in general patient population (64% and 70% compared to 80%), although the difference had no statistical significance (p = 0.6, p = 0.7).     

Biophysical analysis of the acute toxicity of radiotherapy in Hodgkin's lymphoma--a comparison between extended field and involved field radiotherapy based on the data of the German Hodgkin Study Group

PURPOSE: To determine biophysical parameters from the complication probability data during and after radiotherapy of Hodgkin's lymphoma (HL), based on the number of gastrointestinal side effects that were found in the multicenter HD8 trial of the German Hodgkin Lymphoma Study Group. METHODS AND MATERIALS: Between 1993 and 1998, 1204 patients with newly diagnosed, histology-proven HL in clinical Stages I/IIA/IIB with defined risk factors and stage IIIA without risk factors were enrolled into the multicenter HD8 study. Patients were randomized to receive two cycles of COPP (cyclophosphamide, vincristine, procarbazine, prednisone) alternating with two cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) followed by radiotherapy (RT) of 30 Gy extended field plus 10 Gy to bulky disease (Arm A) or 30 Gy involved field plus 10 Gy to bulky disease (Arm B). For 910 patients, the rates of acute gastrointestinal side effects during and after RT could be determined. Comparison showed differences between Arms A and B (Grade 1-2: 16.6 vs. 3.9; Grade 3-4: 0.9 vs. 0.2; p < 0.001). From the dose-volume histograms for a "standard patient" (volume intestine 2300 cm3), we determined the normal tissue complication probability (NTCP) (V, D, m, n, TD50), the biophysical parameter TD50, and n (volume dependent) in such a manner that the observed NTCP in Arm A in cases of supradiaphragmatic involvement only and in cases of infradiaphragmatic involvement correlated with the calculated values. RESULTS: Of 1,204 patients randomized, 1,064 patients were informative for the comparison of study arms. The median observation time was 54 months. The overall survival for all eligible patients was 91%, and freedom from treatment failure was 83%. Survival rates at 5 years after start of RT revealed no differences in terms of freedom from treatment failure (85.8% in Arm A, 84.2% in Arm B) and overall survival (90.8% and 92.4%). There were also no differences between the two arms in terms of complete remission, progressive disease, relapse, death, and secondary neoplasias. In contrast, acute side effects, including leukopenia, thrombocytopenia, nausea, gastrointestinal toxicity, and pharyngeal toxicity, were more frequent in the extended field arm. Concerning gastrointestinal toxicity, the different radiation treatment volumes resulted in different NTCPs. On the basis of these findings, values of n = 0.09 and TD50 = 32 Gy were derived. However, this biophysical model is sensitive to variations of the parameters. A deviation of 1% of TD50 results in a deviation of 10% of the NTCP. CONCLUSION: Radiotherapy volume reduction from extended field to involved field after two cycles of COPP/ABVD chemotherapy gives similar results and less toxicity in patients with early-stage, unfavorable HL. Biophysical parameters could be determined from the complication probability data after RT of HL. Because of the exponential dependence, this biophysical model is unstable. It represents a "start model" until further data can be incorporated.     

Comparison of MOPP versus ABVD as salvage therapy in patients who relapse after radiation therapy alone for Hodgkin's disease.

BACKGROUND: The aim of this study was to determine salvage outcome in patients with Hodgkin's disease who relapse after radiation therapy, and to compare the efficacy of mechlorethamine, Oncovin, procarbazine and prednisone (MOPP) versus Adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) as salvage treatment. PATIENTS AND METHODS: One hundred patients with Hodgkin's disease (97 with stage I-II disease at presentation) who relapsed after radiation therapy alone were salvaged with either MOPP or ABVD. Freedom from second relapse (FFSR) and overall survival (OS) were determined, and prognostic factors for salvage outcome were evaluated. RESULTS: The median follow-up time since salvage therapy was 12 years. The 10-year FFSR and OS rates were 70% and 89%, respectively. Forty-one patients were salvaged with MOPP and 59 received ABVD. The type of salvage chemotherapy did not significantly influence FFSR or OS. Age >50 years at initial diagnosis was the only significant predictor for an inferior FFSR and OS on both univariate and multivariate analyses. CONCLUSIONS: The two salvage regimens of MOPP and ABVD had similar efficacy in this group of patients with predominantly early-stage disease at initial radiation therapy. The inferior salvage outcome in patients aged >50 years is a contributing factor to the overall poor prognosis of patients presenting with Hodgkin's disease at an older age.     

Low-dose radiation therapy and reduced chemotherapy in childhood Hodgkin's disease: the experience of the French Society of Pediatric Oncology.

PURPOSE: With the aim of decreasing undesirable side effects of therapy, we investigated the reduction of both chemotherapy and radiation therapy (RT) in children with Hodgkin's disease, and compared Adriamycin (doxorubicin; Farmitalia Carlo Erba, Rueil-Malmaison, France), bleomycin, vinblastine, and dacarbazine (ABVD) alone to mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and ABVD in favorable cases and assessed the effectiveness of low-dose RT (20 Gy) after good response to chemotherapy. PATIENTS AND METHODS: A French national study began in 1982 that included 238 pediatric patients with Hodgkin's disease. Initial staging was clinical and without laparotomy. In patients with localized disease (IA-IIA), an equivalence trial compared the effectiveness of four cycles of ABVD with two cycles of ABVD that were alternated with two cycles of MOPP. Patients with more advanced disease (IB-IIB-III-IV) received three courses of MOPP that was alternated with three courses of ABVD. All of the patients who achieved a good remission after chemotherapy were administered 20 Gy RT, which was limited to the initially involved areas for localized disease, and encompassed the paraaortic nodes and the spleen as well for more advanced stages. When a good remission was not obtained, 40 Gy RT was administered. RESULTS: At the completion of chemotherapy, 227 patients (97%) were considered good responders, whereas 11 did not achieve a good remission. With a median follow-up of 6 years, the 6-year actuarial survival was 92% and the disease-free survival was 86%. The relapse-free survival in favorable stages was 90% in the ABVD arm and was 87% in the MOPP and ABVD arm. In June 1987, inclusion of stage IV patients was discontinued because of poor results. CONCLUSIONS: Present findings indicate that (1) in favorable stages, ABVD alone and alternating MOPP and ABVD are equivalent, and (2) chemotherapy followed by 20 Gy RT represents a valid therapeutic approach in the vast majority of children with Hodgkin's disease.     

Intermediate stage Hodgkin's disease: preliminary results on 210 patients treated with four ABVD chemotherapy cycles plus extended versus involved field radiotherapy

BACKGROUND: To improve long-term survival by reducing toxicity in intermediate stage Hodgkin's disease patients, we compared the effects of involved field (IF) versus extended field (EF) irradiation administered after four cycles of ABVD regimen. MATERIALS AND METHODS: Two hundred and ten Hodgkin's disease patients, at clinical stage II with risk factors and III without risk factors, were enrolled in the randomized study HD94. After four courses of ABVD regimen, patients who achieved complete remission (CR) or partial remission (PR) were randomly assigned to the IF or EF arm. The Kaplan-Meier method was adopted to estimate overall survival (OS) and relapse-free survival (RFS). RESULTS: After a median follow-up of 78 months (range 13-111 months), OS was 98% and 96%, respectively, in the EF and IF arms; RFS was 94% and 91%, respectively, in the EF and IF arms. Conclusion: We confirm the efficacy of four cycles of ABVD regimen, with suitable dose intensity, and radiotherapy as consolidation therapy, in intermediate stage Hodgkin's disease patients (CR = 99.5% and OS = 95%). We also found that involved field radiotherapy results were as effective as extended field, without acute toxicity.     

Poorer outcome of elderly patients treated with extended-field radiotherapy compared with involved-field radiotherapy after chemotherapy for Hodgkin's lymphoma: an analysis from the German Hodgkin Study Group.

BACKGROUND: The optimal treatment of elderly patients with Hodgkin's lymphoma (HL) is still a matter of debate. Since many of these patients receive combined modality treatment, we evaluated the impact of different radiation field sizes, that is extended-field (EF) or involved-field (IF) technique when given after four cycles of chemotherapy. PATIENTS AND METHODS: In the multicenter HD8 study of the German Hodgkin Study Group, 1204 patients with early-stage unfavorable HL were randomized to receive four cycles of chemotherapy followed by either radiotherapy (RT) of 30 Gy EF + 10 Gy to bulky disease (arm A) or 30 Gy IF + 10 Gy to bulky disease (arm B). A total of 1064 patients were assessable for the analysis. Of these, 89 patients (8.4%) were 60 years or older. RESULTS: Elderly patients had a poorer risk profile. Acute toxicity from RT was more pronounced in elderly patients receiving EF-RT compared with IF-RT [World Health Organization (WHO) grade 3/4: 26.5% versus 8.6%)]. Freedom from treatment failure (FFTF, 64% versus 87%) and overall survival (OS, 70% versus 94%) after 5 years was lower in elderly patients compared with younger patients. Importantly, elderly patients had poorer outcome when treated with EF-RT compared with IF-RT in terms of FFTF (58% versus 70%; P = 0.034) and OS (59% versus 81%; P = 0.008). CONCLUSION: Elderly patients with early-stage unfavorable HL generally have a poorer risk profile and outcome when compared with younger patients. Treatment with EF-RT instead of IF-RT after chemotherapy has a negative impact on survival of elderly patients and should be avoided.     

Intensive chemotherapy and low-dose radiotherapy for the treatment of advanced-stage Hodgkin's disease in pediatric patients: a Pediatric Oncology Group study.

Sixty-two patients with advanced-stage Hodgkin's disease and a median age of 12 years (range, 3 to 22 years) were treated with four cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternating with four cycles of doxorubicin, vinblastine, bleomycin, and dacarbazine (ABVD) followed by low-dose radiotherapy (RT). We determined the feasibility, immediate safety, and rapidity of response of patients to this regimen, as well as the relationship between prognostic factors and the rate of complete remission (CR), event-free survival (EFS), and overall survival. Therapy was well tolerated, and the major toxicity was hematopoietic. At the end of chemotherapy, 54 of 62 patients (87%) were in CR by clinical restaging, with a biopsy of residual disease where necessary. The actuarial 3-year EFS is 77% (SE, 11%), with a median follow-up of 35 months, and the survival is 91% (SE, 7%). With respect to EFS, female patients and those with stage II or III disease fared statistically better than males and patients with stage IV disease, respectively. Six patients have died: three of progressive Hodgkin's disease, one of secondary acute myelocytic leukemia (AML), one of secondary non-Hodgkin's lymphoma (NHL), and one of overwhelming bacterial sepsis. The Pediatric Oncology Group (POG) is currently engaged in a randomized study of these eight cycles of chemotherapy with and without RT to assess the role of RT in achieving comparable results.     

Serum levels of soluble CD30 improve International Prognostic Score in predicting the outcome of advanced Hodgkin's lymphoma.

BACKGROUND: The International Prognostic Score (IPS) and circulating levels of the soluble form of CD30 molecule (sCD30) have both been associated with poor outcome in patients with advanced Hodgkin's lymphoma (HL). The aim of this study was to assess the prognostic power of the combined evaluation of sCD30 and IPS in these patients. PATIENTS AND METHODS: We included 101 patients with advanced HL, treated with ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) or MOPP (mechlorethamine, vincristine, procarbazine and prednisone)/ABVD chemotherapy with or without radiotherapy. All were tested for pre-treatment sCD30 levels. RESULTS: Six-year estimated overall survival (OS) and failure-free survival (FFS) was 89% +/- 3% and 75% +/- 4%, respectively. Thirty-three patients (33%) had IPS >2; their FFS was 60% compared with 82% in the remaining patients (P = 0.027). Serum sCD30 levels were > or =100 U/ml in 41 (41%) patients; their FFS at 6 years was 58%, compared with 87% in patients with sCD30 <100 U/ml (P = 0.003). In the 18 patients with both sCD30 > or =100 U/ml and IPS >2, FFS was significantly worse (44%) than in patients with low sCD30 and low IPS (89%) (P <0.001) or with only one of the two adverse prognostic factors (73%) (P = 0.03). CONCLUSIONS: In our study, the combination of IPS >2 and serum sCD30 levels > or =100 U/ml identifies a sizeable subgroup (18%) of advanced HL patients with very poor FFS, who might take advantage of intensified up-front treatment strategies.     

ABVD (8 cycles) versus BEACOPP (4 escalated cycles ≥4 baseline): final results in stage III–IV low-risk Hodgkin lymphoma (IPS 0–2) of the LYSA H34 randomized trial

BackgroundTreatment with escalated BEACOPP achieved a superior time to treatment failure over ABVD in patients with disseminated Hodgkin lymphoma. However, recent clinical trials have failed to confirm BEACOPP overall survival (OS) superiority over ABVD. In addition, the gain in low-risk patients is still a matter of debate.Patients and methodsWe randomly compared ABVD (8 cycles) with BEACOPP (escalated 4 cycles ≥baseline 4 cycles) in low-risk patients with an International Prognostic Score (IPS) of 0–2. The primary end point was event-free survival (EFS). This parallel group, open-label phase 3 trial was registered under #RECF0219 at French National Cancer Institute.ResultsOne hundred and fifty patients were randomized in this trial (ABVD 80, BEACOPP 70): 28 years was the median age, 50% were male and IPS was 0–1 for 64%. Complete remission rate was 85% for ABVD and 90% for BEACOPP. Progression or relapses were more frequent in the ABVD patients than in the BEACOPP patients (17 versus 5 patients). With a median follow-up period of 5.5 years, seven patients died: six in the ABVD arm and one in the BEACOPP arm (HL 3 and 0, 2nd cancer 2 and 1, accident 1 and 0). The EFS at 5 years was estimated at 62% for ABVD versus 77%, for BEACOPP [hazards ratio (HR) = 0.6, P = 0.07]. The progression-free survival (PFS) at 5 years was 75% versus 93% (HR = 0.3, P = 0.007). The OS at 5 years was 92% versus 99% (HR = 0.18, P = 0.06).ConclusionFewer progressions/relapses were observed with BEACOPP, demonstrating the high efficacy of the more intensive regimen, even in low-risk patients. However, additional considerations, balancing treatment-related toxicity and late morbidity due to salvage may help with decision-making with regard to treatment with ABVD or BEACOPP.     

Evaluation of therapeutic modalities in the control of Hodgkin's disease

The results achieved in three different studies carried out on patients affected by Hodgkin's disease are discussed. In study No. 1, 58 patients with pathological Stage I-II were treated with only a "Mantle" field irradiation. The complete remission (CR) rate was 98% with an actuarial overall survival of 90%, and a median of follow-up of 80 months. Thirty-one percent of patients relapsed. In study No. 2, 42 patients were randomly allocated to receive only MOPP chemotherapy versus extended field irradiation; CR rate was 68 and 95%, respectively (p less than 0.05). The overall survival rate was 100% in the radiotherapy group and 82% in the MOPP group. No relapses have been observed in patients treated with MOPP. In study No. 3, 218 patients affected by advanced Stage HD were randomly treated with 6 cycles of MOPP chemotherapy versus 6 cycles of ABVD chemotherapy. In the MOPP group the CR rate, the relapse-free survival rate (RFS), and overall survival (OS) rates at 60 months were 77, 68, and 76% respectively, whereas, in the ABVD group the CR, the RFS, and OS rates at 60 months were 75, 77 and 80% respectively, (p less than 0.05). These data and statistical comparisons are analyzed.     

Treatment of elderly Hodgkin's lymphoma patients with a novel 5-drug regimen (ODBEP): a phase II study

Elderly patients with Hodgkin's lymphoma (HL) have a worse outcome than young patients. In an effort to improve the outcome in elderly HL patients, we used a 5-drug chemotherapy regimen called ODBEP (vincristine, doxorubicin, bleomycin, etoposide, prednisone) from 1986-1995. We hoped that by increasing dose intensity through delivery of treatment without delays, and increasing the number of non-cross-resistant chemotherapeutic drugs that were selected for minimal cumulative myelotoxicity, we might improve the cure rate in elderly patients with Hodgkin's lymphoma. Comparison was made with a similar group of patients treated from 1981-1986 with MOPP/ABV-variant chemotherapy. Ninety-nine patients who were 65 years or older, were diagnosed with HL from 1981-1995. Seventy-one patients had advanced disease and 55 of this group were treated with curative intent using multi-agent chemotherapy (ODBEP = 38; MOPP/ABV-variant = 17). ODBEP and MOPP/ABV-type treatment gave a median survival of 43 and 39 months, with 5-year overall survival (OS) of 42 and 32%, respectively. There was no statistically significant difference in OS or disease specific survival between the treatments. Both treatments were well tolerated, but ODBEP was less myelotoxic. ODBEP patients had a relative risk of 0.47 of developing febrile neutropenia compared to the MOPP/ABV-variant patients. In conclusion, treatment of elderly Hodgkin's lymphoma patients with ODBEP resulted in a similar OS and disease-specific survival compared to those treated with MOPP/ABV type chemotherapy, but appeared to be less toxic.     

High-dose sequential chemotherapy and peripheral blood progenitor cell autografting in patients with refractory and/or recurrent Hodgkin lymphoma: a multicenter study of the intergruppo Italiano Linfomi showing prolonged disease free survival in patients treated at first recurrence

BACKGROUND: The objective of the current study was to evaluate in a multicenter setting the feasibility and efficacy of a high-dose sequential (HDS) chemotherapy regimen that combined intensive debulking and high-dose therapy (HDT) with peripheral blood progenitor cell (PBPC) autografting in patients with refractory or recurrent Hodgkin lymphoma (HL). METHODS: Data were collected from 102 patients with HL who were treated with the HDS regimen at 14 centers associated with the Intergruppo Italiano Linfomi. Twenty-four patients had primary refractory HL, 59 patients had their first recurrence of HL (within 1 year in 32 patients and > 1 year in 27 patients), and 19 patients had multiple disease recurrences. The HDS regimen included the sequential delivery of high-dose (hd) cyclophosphamide with PBPC harvesting, methotrexate, etoposide, then HDT (usually hd mitoxantrone plus L-phenylalanine mustard) with PBPC autografting. In addition, radiotherapy was delivered to 36 patients at sites of bulky or persistent disease. RESULTS: Ninety-two patients (90%) completed the HDS program. There were five toxic deaths (treatment-related mortality rate, 4.9%) and six secondary malignan cies (five patients developed myelodysplastic syndrome/acute myelogenous leukemia, and one patient developed colorectal carcinoma). At a median follow-up of 5 years, the 5-year overall survival (OS) and event-free survival (EFS) projections were 64% (95% confidence interval [95% CI], 54-74%) and 53% (95% CI, 43-63%), respectively. Patients with their first recurrence had the most favorable outcome, with 5-year OS and EFS projections of 77% (95% CI, 66-88%) and 63% (95% CI, 50-76%), respectively. There were no significant differences between patients with early first recurrence and late first recurrence. The poorest outcome was observed in patients with refractory HL, with 5-year OS and EFS projections of 36% (95% CI, 16-55%) and 33% (95% CI, 14-52%), respectively. Patients who received HDS chemotherapy after multiple recurrences had an intermediate outcome. Multivariate analysis showed that refractory disease and systemic symptoms at the time of initial presentation were associated significantly associated with poor OS and EFS. CONCLUSIONS: The use of HDS chemotherapy for patients with refractory and/or recurrent HL is feasible at the multicenter level. The combination of intensive debulking and HDT with PBPC autografting offers a good chance of prolonged disease free survival for patients with their first recurrence of HL.     

Survival Results and Prognostic Factors in T4 N0-3 Non-small Cell Lung Cancer Patients According to the AJCC 7th Edition Staging System

Background: The American Joint Committee on Cancer (AJCC) published a new staging system (7th edition)in 2009. In our study, we evaluated the survival results and prognostic factors among T4 local advanced nonsmallcell lung cancer (LA-NSCLC) patients in a large heterogeneous group, in accordance with this new system.Materials and Methods: We retrospectively evaluated the files of 122 T4 N0-3 M0 LA-NSCLC patients, identifiedaccording to the new staging system, treated at two centers between November 2003 and June 2012. Variablescorrelating with univariate survival at p<0.20 were later included in multivariate Cox regression analysis. Here,selection of relevant predictors of survival was carried out in accordance with the likelihood ratio formulawith p<0.05 regarded as significant. Results: The median age was 60 and the median follow-up period was 17.4months. Median overall survival (OS) was 18.3 months, the 1 year overall survival (OS) rate was 72%, andthe 5 year OS rate was 28%. Statistically significant predictors of survival were (p<0.20) ECOG-PS (EasternCooperative Oncology Group Performance Status), age, T4 factor subgroup, stage and primary treatment inOS univariate analysis. On multivariate analysis for OS ECOG-PS (p=0.001), diagnostic stage (p=0.021), andprimary treatment (p=0.004) were significant. In the group receiving non-curative treatment, the median OSwas 11.0 months, while it was 19.0 months in the definitive RT group and 26.6 months in the curative treatmentgroup. There was a significant difference between the non-curative group and the groups which had definitiveRT and curative operations (respectively p<0.001 and p=0.001) in terms of OS, but not between the groupswhich had definitive RT and curative operations. The median event free survival (EFS) rate was 9.9 months,with rates of 46% and 19% at 3 and 5 years, respectively. On univariate analysis of EFS rate with ECOG-PS,weight loss and staging, statistical significance was found only for thorax computerized tomography (CT)+18Ffluorodeoxy-glucose positron emission tomography-CT (PET-CT) use, stage and primary treatment (p<0.20). Inmultivariate analysis with EFS, only the primary treatment was statistically significant (p=0.001). In the groupreceiving non-curative treatment, the median EFS was 10.5 months while in the curative operation group it was14.7 months. When all the primary treatment groups were taken into consideration, grade III/IV side effectswas observed in 57 patients (46.6%). Esophagitis was most prominent among those that received definitiveradiotherapy. Conclusions: Independent prognostic factors among these 122 heterogeneous LA-NSCLC T4 N0-3M0 patients were age at diagnosis, ECOG-PS, stage and primary treatment, the last also being a significantprognostic indicator of EFS. Our findings point to the importance of appropriate staging and a multidisciplinaryapproach with modern imaging methods in this patient group. In those with T4 lesions, treatment selection andthe effective use of curative potential should be the most important goal of clinical care.
