Quality of life assessment in elderly patients with aggressive non-Hodgkin's Lymphoma treated with anthracycline-containing regimens. Report of a prospective study by the Intergruppo Italiano Linfomi.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate quality of life (QOL) in a group of elderly patients (> 65 years) with aggressive non-Hodgkin's lymphoma (NHL) treated with chemotherapy regimens containing anthracyclines. DESIGN AND METHODS: QOL was evaluated in a population of elderly patients with aggressive NHL enrolled in a phase III clinical trial run by the Intergruppo Italiano Linfomi (IIL) from 1996 to 1999 to compare two different anthracycline-containing regimens (mini-CEOP vs P-VEBEC). The EORTC-QLQ-C30 questionnaire, which has already been validated in oncology, was used. The questionnaire was administered at the time of diagnosis, half way through the chemotherapy and at the time of restaging. RESULTS: Ninety-one patients completed pre-therapy and post-therapy questionnaires and they are the subject of this report. Baseline QOL assessment showed a strong correlation of poor values of QOL with anemia and high risk according to the International Prognostic Index (IPI). At the end of treatment no functional scales showed worse values. A significant improvement was observed for pain (p=0.003), appetite (p=0.006), sleep (p=0.015) and global health (p=0.027). Considering only the 50 patients who achieved a complete remission (CR), an improvement was also recorded for emotional state (p=0.10), role (p=0.05), constipation (p=0.04) and global QOL (p=0.05). INTERPRETATION AND CONCLUSIONS: The EORTC-QLQ-C30 is feasible even in a population of elderly patients, in whom it had never been tested before. The improvement of QOL at the end of the treatment demonstrated that the symptoms of the disease have a greater negative influence on the patient's life than do the side effects of the therapy.

Vinblastine, bleomycin, and methotrexate chemotherapy plus irradiation for patients with early-stage, favorable Hodgkin lymphoma: the experience of the Gruppo Italiano Studio Linfomi.

BACKGROUND: The acknowledged effectiveness of vinblastine, bleomycin, and methotrexate (VBM) chemotherapy in patients with early-stage Hodgkin lymphoma has been associated with conflicting toxicity reports. METHODS: One hundred forty-three patients were evaluated clinically and had favorable Stage IA or IIA Hodgkin lymphoma. Ninety-three patients were treated with the standard VBM schedule combined with extended-field radiotherapy (EF-RT), leaving the choice of the therapeutic sequence free. Fifty subsequent patients were treated with a slightly modified VBM schedule (VbMp) combined with RT limited to involved fields (IF-RT) and delivered only after the end of chemotherapy. In the VbMp schedule, intervals between cycles were 21 days instead of 28 days, bleomycin doses were reduced, small doses of prednisone were given orally, and the interval before RT was prolonged. RESULTS: Clinical response was complete in 96% of patients who were treated with VBM plus EF-RT and in 94% of patients who were treated with VbMp plus IF-RT. Recurrence rates were nearly identical (12% and 11%, respectively) over necessarily different follow-up (91 months and 33 months, respectively). Hematologic toxicity was tolerable in both trials, and pulmonary side effects were moderate in the first trial and negligible in the second. On the whole, treatment was tolerated better when RT followed chemotherapy. CONCLUSIONS: The VBM regimen was confirmed to be effective in patients with early-stage Hodgkin lymphoma. Administration of all cycles before RT improved tolerance; pulmonary toxicity probably is mitigated further by reduced bleomycin doses, mild prednisone therapy, and a more prolonged resting interval before RT. A slightly higher recurrence rate was expectable in the VBM plus IF-RT trial despite the actual intensification of vinblastine and methotrexate.

Peripheral T-cell lymphoma unspecified (PTCL-U): a new prognostic model from a retrospective multicentric clinical study.

To assess the prognosis of peripheral T-cell lymphoma unspecified, we retrospectively analyzed 385 cases fulfilling the criteria defined by the World Health Organization classification. Factors associated with a worse overall survival (OS) in a univariate analysis were age older than 60 years (P=.0002), equal to or more than 2 extranodal sites (P=.0002), lactic dehydrogenase (LDH) value at normal levels or above (P<.0001), performance status (PS) equal to or more than 2 (P< or =.0001), stage III or higher (P=.0001), and bone marrow involvement (P=.0001). Multivariate analysis showed that age (relative risk, 1.732; 95% CI, 1.300-2.309; P<.0001), PS (relative risk, 1.719; 95% CI, 1.269-2.327, P<.0001), LDH level (relative risk, 1.905; 95% CI, 1.415-2.564; P<.0001), and bone marrow involvement (relative risk, 1.454; 95% CI, 1.045-2.023; P=.026) were factors independently predictive for survival. Using these 4 variables we constructed a new prognostic model that singled out 4 groups at different risk: group 1, no adverse factors, with 5-year and 10-year OS of 62.3% and 54.9%, respectively; group 2, one factor, with a 5-year and 10-year OS of 52.9% and 38.8%, respectively; group 3, 2 factors, with 5-year and 10-year OS of 32.9% and 18.0%, respectively; group 4, 3 or 4 factors, with a 5-year and 10-year OS of 18.3 and 12.6%, respectively (P< or =.0001; log-rank, 66.79).

Incidence of AIDS-defining cancers after AIDS diagnosis among people with AIDS in Italy, 1986-1998.

A record linkage was carried out between the Italian National Registry of AIDS and 19 cancer registries. The aim was to evaluate the 1986 through 1998 trends in incidence rate (IR) of AIDS-defining cancers (ADCs) among persons with AIDS (PWA) in Italy overall and according to various characteristics. A steady decrease in IRs was found for Kaposi sarcoma (KS) in men between 1986-1992 (2.5 per 100 person-years [py]) and 1997-1998 (1.0 per 100 py). Conversely, the first decrease in IRs of KS in women (from 0.9 to 0.6 per 100 py) and of non-Hodgkin lymphoma in both genders (from 1.7 to 0.7 per 100 py) was seen between 1993-1996 and 1997-1998, thus pointing to a favorable impact of highly active antiretroviral therapies. The decline was consistent across different age and HIV transmission groups, but it was more marked in PWA with a CD4 count >50 cells/microL than in PWA with more severe immune suppression. As a proportion of AIDS cases, invasive cervical cancer increased from 1.5% in 1993-1996 to 2.4% in 1997-1998, but IRs after AIDS could not be evaluated. On account of the marked decline of KS in men in 1997-1998, the overall burden of ADCs in Italy became similar in both genders.

High-dose therapy and autologous stem-cell transplantation versus conventional therapy for patients with advanced Hodgkin's lymphoma responding to front-line therapy.

PURPOSE: To determine whether high-dose therapy (HDT) with autologous stem-cell transplantation (ASCT) should be included in the initial consolidative treatment of patients with advanced, unfavorable Hodgkin's lymphoma (HL). PATIENTS AND METHODS: One hundred sixty-three patients achieving complete remission (CR) or partial remission (PR) with four initial courses of doxorubicin, bleomycin, vinblastine, and dacarbazine, or other doxorubicin-containing regimens, were randomly assigned to receive HDT plus ASCT (83 patients) versus four courses of conventional chemotherapy (80 patients). Unfavorable HL was defined as the presence of at least two of the following poor prognostic factors: high lactate dehydrogenase level, large mediastinal mass (greater than at least 33% of the thoracic diameter), more than one extranodal site, low hematocrit level, and inguinal involvement. RESULTS: At the end of the treatment program, 92% of patients in arm A and 89% in arm B achieved a CR (P =.6). After a median follow-up of 48 months, the 5-year failure-free survival rates were 75% (95% confidence interval [CI], 65 to 85) in arm A and 82% (95% CI, 73 to 90) in arm B (P =.4). The 5-year overall survival rates were 88% (95% CI, 80 to 96) in arm A and 88% (95% CI, 79 to 96) in arm B (P =.99). The 5-year relapse-free survival rates were 88% in arm A (95% CI, 80 to 96) and 94% in arm B (95% CI, 88 to 100), and the difference was not significant (P =.3). CONCLUSION: Patients with advanced unfavorable HL achieving CR or PR after four courses of doxorubicin-containing regimens have a favorable outcome with conventional chemotherapy. No benefit from an early intensification with HDT and ASCT was shown.

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.

Treatment of indolent B-Cell nonfollicular lymphomas: final results of the LL01 randomized trial of the Gruppo Italiano per lo Studio dei Linfomi.

PURPOSE: To evaluate the effect of epirubicin on therapeutic response and survival in patients with indolent nonfollicular B-cell lymphomas (INFL) treated with pulsed high-dose chlorambucil. PATIENTS AND METHODS: A total of 170 untreated patients with advanced/active INFL were randomly assigned to receive either eight cycles of high-dose chlorambucil (15 mg/m2/d) plus prednisone (100 mg/d) for 5 days (HD-CHL-P; arm A) or eight cycles of HD-CHL-P plus epirubicin 60 mg/m2 intravenous on day 1 (arm B). The responding patients were randomly assigned to either maintenance therapy with interferon alfa (IFNalpha-2a; 3 MU, three times weekly) for 12 months or observation. RESULTS: There were 160 assessable patients (82 males, 78 females; median age, 63 years; range, 33 to 77 years); 77 patients were assigned to arm A, and 83 were assigned to arm B. Induction therapy led to 47 complete responses (CRs; 29.4%) and 68 partial responses (PRs; 42.5%), with no significant difference between the two arms (60 CR + PR in arm A [77.9%] and 55 CR + PR in arm B [66.3%]; P =.07). After a median follow-up of 38 months (range, 2 to 103 months), there was no between-group difference in overall survival (OS; P =.45), failure-free survival (P =.07), or progression-free survival (PFS; P =.5). Eighty-eight patients were randomly assigned to either IFNalpha-2a (n = 43) or observation (n = 45), without any difference in 3-year PFS (44% and 42%, respectively). Univariate analysis showed that OS was influenced by age, anemia, serum lactate dehydrogenase levels, and International Prognostic Index distribution; multivariate analysis identified age and anemia as having influence on OS. CONCLUSION: HD-CHL-P treatment outcome in INFL patients was good (50% 3-year PFS, minimal toxicity, and low costs); epirubicin did not add any advantage. One-year IFNalpha maintenance treatment did not prolong response duration.

Different expressivity of BRCA1 and BRCA2: analysis of 179 Italian pedigrees with identified mutation.

Mutations in BRCA1 and BRCA2 show different expressivity with respect to cancer risk, and allelic heterogeneity may be present in both genes. We collected 179 pedigrees with identified germline mutation (104 BRCA1 and 75 BRCA2), ascertained in six collaborating centers of the Italian Consortium for Hereditary Breast and Ovarian Cancer. Significant heterogeneity was detected for several variables, and a logistic regression model including age of diagnosis in the proband, presence of ovarian cancer in the family, presence of prostate or pancreatic cancer in the family, and presence of male breast cancer in the family proved to be effective in predicting the presence of a mutation in a gene rather than the other. Excess of familial aggregation of both breast and ovarian cancer was observed in both genes. Proportion of ovarian cancer was increased in the 5' portion of BRCA1, and presence of prostate or pancreatic cancer in a family was correlated with presence of ovarian cancer in BRCA2.

Italian family with two independent mutations: 3358T/A in BRCA1 and 8756delA in BRCA2 genes.

Hereditary breast/ovarian cancer is a well-characterized clinical entity, largely attributed to the inheritance of BRCA1 or BRCA2 mutations. Among general population, the mutation's frequency of these genes is very low; therefore, the identification of two independent mutations in the same family is a rare event. This study reports the presence of two mutations, one in the BRCA1 and the second in the BRCA2 gene in an Italian Caucasian kindred. This family is composed of more than 250 individuals, spanning through five generations, among which endogamy was a common phenomenon. Considering the tumor spectrum, this family is characterized by a high incidence of different types of cancer. In our study, we considered only three out of seven family units for BRCA1 and BRCA2 analysis. In one of the family units, we found independent mutations of both BRCA genes. The BRCA1 mutation on exon 11 (3358T-->A) was identified originally in the index case and subsequently in 18 members of this family, whereas the same mutation was not detected in a related family member with male breast cancer. The male breast cancer patient led to the identification, through mutational analysis, of a new BRCA2 mutation (8756delA). This BRCA2 mutation was also found in the male breast cancer patient's daughter. The discovery of the BRCA2 mutation allowed us to alert the patient's daughter who, otherwise, could be falsely reassured since she had a negative BRCA1 test.

Prevalence and prognostic significance of sMUC-1 levels in plasma cell dyscrasias.

High serum Mucin-1 (sMUC-1) levels have been shown in patients with adenocarcinoma and multiple myeloma (MM). We evaluated sMUC-1 levels in 76 patients with MM, 6 with plasma cells leukaemia (PCL) and 89 with monoclonal gammopathy of undetermined significance, to establish prevalence data and verify its possible prognostic role. Of the 171 patients, 27 [16%; 95% confidence interval (CI): 10-21%] had high sMUC-1 levels compared with healthy subjects (1.5%; 95% CI: 0-4%). Elevated sMUC-1 levels in MM and PCL patients correlated with anaemia and elevated serum lactate dehydrogenase levels; these patients showed a shorter survival than those with normal sMUC-1 levels (median overall survival: 25 vs. 49 months, P = 0.003).

The role of anthracyclines in combination chemotherapy for the treatment of follicular lymphoma: retrospective study of the Intergruppo Italiano Linfomi on 761 cases.

In order to elucidate the role of anthracycline based combination chemotherapy regimens for the treatment of follicular lymphoma we conducted a retrospective study on a large series of patients with a histologically confirmed diagnosis of follicular lymphoma. The Italian lymphoma intergroup (ILI) promoted a retrospective study of patients with follicular lymphoma treated in cooperative trials between 1985 and 1996. Six hundred and thirty three cases were treated with an anthracycline-containing regimen and 128 patients were treated without anthracyclines. The two groups were prognostically comparable; in particular, no difference was observed according to both IPI and ILI prognostic index. Results showed a complete remission (CR) rate for patients treated with anthracyclines was 69.2% and overall response rate was 92.5%. After a median follow-up of 51 months (54 months for patients still alive), the 5- and 10-year overall survival (OS) rates were 80 and 66%, respectively. Disease-free survival (DFS) and failure-free survival (FFS) rates at 5 years were 61 and 49%, respectively. In the group of patients treated with combination chemotherapy not including anthracyclines, the CR rate was 67.5% and the overall response rate was 85.4%. A longer OS (80% at 5 years) was observed in patients treated with anthracyclines compared to 67% OS rate in patients treated without anthracyclines (p = 0.0004). FFS was significantly longer in patients treated with anthracyclines (49 vs. 34% p = 0.006). Patients treated with anthracyclines with low or intermediate risk according to ILI prognostic index showed a significantly longer OS (p = 0.0001 andp = 0.0009, respectively); those in the high-risk group showed a trend for a longer survival. In conclusion, this retrospective study shows that patients with follicular lymphoma treated with an anthracycline containing regimen had a better outcome compared to patients treated with other combination regimens non including anthracyclines in terms of CRs, OS and FFS. On the basis of these results anthracycline-containing regimens (ACR) should be considered as the standard treatment of patients with advanced follicular lymphoma.

Risk of second cancer in patients with hairy cell leukemia: long-term follow-up.

PURPOSE: The purpose of the present study was to assess the risk of second cancers in patients with hairy cell leukemia (HCL). PATIENTS AND METHODS: We investigated the incidence of additional cancers in those patients registered in the nationwide registry of the Italian Cooperative Group for the Study of HCL, asking the cooperating centers for additional information on initial and subsequent therapies and on time and type of second malignancies, if they developed. Here we report the final results of this survey, consisting of 54 cases of second malignancies (excluding nine cases of epithelial skin cancer) which developed in 54 patients of 1,022 with adequate follow-up. RESULTS: The cumulative risk of development of a second cancer was 5%, 10%, and 14% at 5, 10, and 15 years, respectively. The incidence of second malignancies was not significantly higher than the expected rate (standardized incidence ratio [SIR], 1.01; 95% confidence interval [CI], 0.74 to 1.33; P = 1.0). However, the SIR of non-Hodgkin's lymphoma in the entire cohort was 5.3 (95% CI, 1.9 to 11.5). Second malignancies occurred in eight (4.7%) of 386 patients who never received interferon (IFN), nine (5.9%) of 495 patients treated with IFN at the time of diagnosis, and seven (6.9%) of 102 patients who received IFN as second-line therapy. These differences were not statistically significant. Analysis of the separate calendar periods did not reveal any particular trends with respect to variations in SIR. CONCLUSION: The present study does not support the suspicion that patients with HCL are at increased risk of additional second malignancies, although the incidence of lymphoid neoplasms was significantly higher than expected. In addition, our data indicate that IFN therapy did not exert an oncogenic effect in such patients.

Stage-specific incidence of breast cancer before the beginning of organized screening programs in Italy.

OBJECTIVE: To measure stage-specific geographic and time variability of breast cancer in seven Italian areas before the onset of organized screening programs. METHODS: All invasive cancers (8689 cases) arising in women aged 40-79 years during the pre-screening period 1985-1997, were considered. Multiple Poisson regression analysis was performed. RESULTS: About 39% of the cases were classified as "early," 52% as "advanced," and 9% as "unspecified" stage. Age-adjusted incidence rates showed a significant geographic variation for early but not for advanced cancers (range: 58-103 cases/100,000 and 104-125 cases/100,000, respectively). The result was confirmed in the multiple regression analysis after adjustment for year of diagnosis and age. Early breast cancer risk adjusted for age and registry showed a significant increase over time (+3.9% per year for all ages, and +6.2% per year for age category 50-79). In contrast, a decreasing time trend was observed for advanced cancer of 3 cm or over in women aged less than 60. CONCLUSIONS: In our study, early breast cancer incidence varied both by geographic area and time before the commencement of screening. The differences in early-stage incidence may well be related to differences in availability of "spontaneous" mammography. Late-stage incidence decreased over time in younger women and for very advanced cases, but not in the older ones, nor for cancers less than 3 cm. Early detection outside organized screening was only partially efficient in reducing advanced breast cancer incidence. The trend of incidence of advanced disease, as previously proposed, is confirmed to be a valid early indicator of effectiveness of screening.

Changes in breast cancer incidence and stage distribution in Modena, Italy: the effect of a mammographic screening program.

OBJECTIVE: Assessing changes in breast cancer (BC) incidence and stage distribution in the District of Modena, Italy, during the period 1992-1998, and their relationship to a mammographic screening program launched in 1995. METHODS: Demographic, clinical, and pathological data of all BC cases reported to the population-based Modena Cancer Registry between 1992 and 1998 were collected and linked to the screening database. RESULTS: A total of 3429 women were diagnosed with BC in the District of Modena between 1992 and 1998. In this period the incidence rate increased by 15.7% (from 134.3 in 1992 to 155.4 per 100,000 in 1998). The increase began in 1995 and exclusively included women aged 50-69; the incidence rose by 30.4%. Moreover, the rise was confined to early tumors, with more than half (54%) of all cases reported in 1998 diagnosed as stage 0 or I disease, compared with 42% in 1992. Screen-detected tumors were significantly smaller (13.2 mm) than other tumors diagnosed in women aged 50-69 (18.5 mm), with 46% of screen-detected tumors smaller than 10 mm. Overall, a decline in the average tumor diameter was shown (from 20.2 mm in 1992-1994 to 18 mm in 1996-1998). CONCLUSIONS: Our data confirm that mammographic screening leads to an increase in the incidence of early-stage BC cancers.

Bleomycin, epidoxorubicin, cyclophosphamide, vincristine and prednisone (BACOP) in patients with follicular non-Hodgkin's lymphoma: results of a prospective, multicenter study of the Gruppo Italiano Per Lo Studio Dei Linfomi (GISL).

At present we report the results of a prospective, non-randomized open trial, conducted on follicular lymphoma (FL) patients by the Gruppo Italiano per lo Studio dei Linfomi (GISL), after a median follow-up of 62.6 months. Seventy-three patients with FL were registered to the study and treated with combination chemotherapy consisting of cyclophosphamide, epidoxorubicin, vincristine, bleomycin and prednisone, weekly administered every 4 weeks. After chemotherapy, involved-field radiotherapy was delivered in case of either localized, bulky and extranodal disease at presentation or limited residual disease at the end of chemotherapy. Patient received four or eight chemotherapy courses in case of localized or advanced disease, respectively. The overall response rate at the end of the treatment program was 97.3%, with 78.1% CR and 19.2% PR. CR rate was 94.3 and 63.1% in stage I-II and III-IV, respectively (p = 0.006). Beside the stage, response rate was significantly influenced by bone marrow involvement, and the number of extranodal sites. Relapse free survival was 60.8% at 5 years in the whole series; in localized disease it was 70.3 vs. 44.8% in advanced disease (p = 0.044). Relapse free survival was significantly influenced by stage, bone marrow involvement, number of extranodal sites and International Prognostic Index (IPI) score. The overall 5-year survival rate was 90.2%; being 95.6% for patients with stage I-II and 85.1% for those III-IV (p = 0.0133). In addition, both IPI and Italian Lymphoma Intergroup (ILI) score had a significant impact on survival. The toxicity profile of the treatment was acceptable. From the results of this prospective study it is possible to conclude that this regimen and the whole treatment program is effective as first line therapy for the general population of FL. In particular the BACOP schedule is a valid anthracycline-containing regimen, and in this respect suitable to be considered as a treatment option.

Prospective study of indolent non-follicular non-Hodgkin's lymphoma: validation of Gruppo Italiano per lo studio dei linfomi (GISL) prognostic criteria for watch and wait policy.

Only recently both the Revised European American Lymphoma (REAL) and World Health Organization (WHO) classifications clearly identified indolent non-follicular non-Hodgkin's lymphoma (NHL) as a distinct group of precise histological entities. Therefore, prognostic models, specifically designed for this NHL subset, are still lacking. In this study, we prospectically evaluated the prognostic criteria proposed by the Gruppo Italiano per lo studio dei linfomi (GISL) to identify patients with an indolent non-progressive clinical course, eligible for a watch and wait policy within this histological subset defined according to stringent criteria of histomorphology and immunophenotype. Fifty-three patients affected with small lymphocytic, marginal zone, lymphoplasmacytic lymphoma and lacking at presentation the following: B symptoms, bulky disease, anemia, thrombocytopenia, diffuse pattern of bone marrow infiltration and short tumor doubling time, were registered in a prospective therapeutic GISL trial and addressed to a watch and wait program. After 41.3 months of median follow-up, the median progression free survival (PFS) was not reached and 73% of cases did not progress. When additional variables were considered, in order to improve the prognostic model, it was evident that LDH level and the number of extranodal sites were of statistical significance in the multivariate analysis. Based on this finding, a prognostic score was devised which was able to further identify a small group of patients more likely to undergo early progression, and thus suitable for immediate treatment. In conclusion, the GISL definition of indolent disease is a reliable tool to design the appropriate therapeutic strategy in this histological setting.

Induction chemotherapy strategies for primary mediastinal large B-cell lymphoma with sclerosis: a retrospective multinational study on 426 previously untreated patients.

BACKGROUND AND OBJECTIVES: This multinational retrospective study compares the outcomes of patients with primary mediastinal large B-cell lymphoma (PMLBCL) with sclerosis after first-generation (dose-intensive regimens), third-generation (alternating regimens) and high-dose chemotherapy strategies, frequently with adjuvant radiation therapy. DESIGN AND METHODS: Between August 1981 and December 1999, a total of 426 previously untreated patients with confirmed diagnosis were enrolled in 20 institutions to receive combination chemotherapy with either first generation (CHOP or CHOP-like) regimens, third generation (MACOP-B, VACOP-B, ProMACE CytaBOM) regimens or high-dose chemotherapy (HDS/ABMT). RESULTS: With chemotherapy, complete response (CR) rates were 49% (50/105), 51% (142/277) and 53% (23/44) with first generation, third generation and high-dose chemotherapy strategies, respectively; partial response (PR) rates were 32%, 36% and 35%, respectively. All patients who achieved CR and 124/142 (84%) with PR had radiation therapy on the mediastinum. The final CR rates became 61% for CHOP/CHOP-like regimens, 79% for MACOP-B and other regimens, and 75% for HDS/ABMT. After median follow-ups from attaining CR of 48.5 months for CHOP/CHOP-like regimens, 51.7 months for MACOP-B type regimens and 32.4 months for HDS/ABMT, relapses occurred in 15/64 (23%), 27/218 (12%) and 0/33 (0%) patients, respectively. Projected 10-year progression-free survival rates were 35%, 67% and 78%, respectively (p=0.0000). Projected 10-year overall survival rates were 44%, 71% and 77%, respectively (p=0.0000), after median follow-ups from diagnosis of 52.3 months, 54.9 months and 35.8 months, respectively. INTERPRETATION AND CONCLUSIONS: In patients with PMLBCL with sclerosis, MACOP-B plus radiation therapy may be a better strategy than other treatments; these retrospective data need to be confirmed by prospective studies. The encouraging survival results after high dose chemotherapy require confirmation in selected high-risk patients.
