RESUMO

PURPOSE: Gemcitabine plus cisplatin (GC) and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) were compared in patients with locally advanced or metastatic transitional-cell carcinoma (TCC) of the urothelium. PATIENTS AND METHODS: Patients with stage IV TCC and no prior systemic chemotherapy were randomized to GC (gemcitabine 1,000 mg/m2 days 1, 8, and 15; cisplatin 70 mg/m2 day 2) or standard MVAC every 28 days for a maximum of six cycles. RESULTS: Four hundred five patients were randomized (GC, n = 203; MVAC, n = 202). The groups were well-balanced with respect to prognostic factors. Overall survival was similar on both arms (hazards ratio [HR], 1.04; 95% confidence interval [CI], 0.82 to 1.32; P = .75), as were time to progressive disease (HR, 1.05; 95% CI, 0.85 to 1.30), time to treatment failure (HR, 0.89; 95% CI, 0.72 to 1.10), and response rate (GC, 49%; MVAC, 46%). More GC patients completed six cycles of therapy, with fewer dose adjustments. The toxic death rate was 1% on the GC arm and 3% on the MVAC arm. More GC than MVAC patients had grade 3/4 anemia (27% v 18%, respectively) and thrombocytopenia (57% v 21%, respectively). On both arms, the RBC transfusion rate was 13 of 100 cycles and grade 3/4 hemorrhage or hematuria was 2%; the platelet transfusion rate was four patients per 100 cycles and two patients per 100 cycles on GC and MVAC, respectively. More MVAC patients, compared with GC patients, had grade 3/4 neutropenia (82% v 71%, respectively), neutropenic fever (14% v 2%, respectively), neutropenic sepsis (12% v 1%, respectively), and grade 3/4 mucositis (22% v 1%, respectively) and alopecia (55% v 11%, respectively). Quality of life was maintained during treatment on both arms; however, more patients on GC fared better regarding weight, performance status, and fatigue. CONCLUSION: GC provides a similar survival advantage to MVAC with a better safety profile and tolerability. This better-risk benefit ratio should change the standard of care for patients with locally advanced and metastatic TCC from MVAC to GC.

RESUMO

BACKGROUND: Breast cancer diagnosed during pregnancy (BCP) is rare, but the prevalence is expected to rise. Long-term follow-up data regarding this clinically challenging condition are scarce. The main objective of this multicentre case-control French study was to compare the survival between pregnant patients and matched controls. METHODS: Patients from 27 centres diagnosed between 2000 and 2009 with histologically proven invasive breast cancer occurring during pregnancy were retrospectively included. Controls were matched to BCP patients on age, clinical T stage, hormone receptor, HER2, administration of neo-adjuvant chemotherapy and pathological node involvement in the absence of neo-adjuvant chemotherapy. Five-year overall survival (OS), disease-free survival (DFS) and metastasis-free survival (MFS) rates were estimated using the Kaplan-Meier method. RESULTS: One hundred and eleven BCP patients and 253 controls were included. Median age was 33 and 35 years, respectively. Both populations were managed similarly, except for less frequent sentinel node dissection (p = 0.026) and taxane administration (p = 0.03) among BCP patients. Median follow-up was 7.5 years. Survival rates were similar between both BCP and control patients: 5-year OS rates were 83.1% (95% CI: 74.5-89.0) vs 85.5% (95% CI: 80.4-89.4), respectively, p = 0.31; 5-year DFS rates 60.0% (95% CI: 50.1-68.6) vs 68.5% (95% CI: 62.3-73.9), respectively, p = 0.12 and 5-year MFS rates 71.0% (95% CI: 61.3-78.6) and 74.5% (95% CI: 68.6-79.5), respectively, p = 0.21. CONCLUSION: Our study showed that the survival outcomes of patients diagnosed with BCP were not significantly different as compared to those of matched non-pregnant controls. A proper management of women diagnosed with BCP is crucial.

RESUMO

BACKGROUND: The GETUG 13 phase III trial tested personalised chemotherapy based on tumour marker decline in patients with poor-prognosis germ-cell tumour (GCT) and demonstrated that a dose-dense regimen improves progression-free survival in patients with an unfavourable decline. We investigated the pattern of relapse for patients included in GETUG 13. METHODS: We conducted an analysis of relapse events in patients from GETUG 13. Baseline procedures before inclusion in the trial comprised a thoraco-abdomino-pelvic computed tomography scan and a magnetic resonance imaging of the brain. RESULTS: With a median follow-up of 4.1 years (0.3; 8.8 years), a progression event was observed in 109/254 patients (43%). First event consisted in a marker progression only in 47 patients (43%), a radiographic progression only in 35 patients (32%), a mix progression on both markers and imaging in 12 patients (11%) and death in 15 patients (14%). In patients with radiographic progression only, brain was the predominant site (n = 19/35, 54%). Among patients with unfavourable decline who experienced a radiographic progression (as first and subsequent progression event, n = 58), brain was a site of progression in 28 patients (48%): 12/30 (40%) in patients treated with cisplatin, bleomycin and etoposide and 16/28 (57%) in those treated with dose-dense chemotherapy. CONCLUSIONS: Brain metastases develop often, early and frequently as the only site of relapse in the course of poor-prognosis GCT. This raises the question of early detection and optimal treatment of brain metastases in these patients, e.g. by integrating a systematic brain MRI after 2-3 months of chemotherapy.

RESUMO

BACKGROUND: Sarcomas are rare but aggressive diseases. Specialized multidisciplinary management is not implemented for all patients in most countries. We investigated the impact of a multidisciplinary tumor board (MDTB) presentation before treatment in a nationwide study over 5 years. PATIENTS AND METHODS: NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized MDTB, funded by the French National Cancer Institute to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB and second pathological review are mandatory for sarcoma patients in France. Patients' characteristics and follow-up are collected in a database regularly monitored and updated. The management and survival of patients presented to these MDTB before versus after initial treatment were analyzed. RESULTS: Out of the 12 528 patients aged ≥15 years, with a first diagnosis of soft tissue and visceral sarcoma obtained between 1 January 2010 and 31 December 2014, 5281 (42.2%) and 7247 (57.8%) were presented to the MDTB before and after the initiation of treatment, respectively. The former group had generally worse prognostic characteristics. Presentation to a MDTB before treatment was associated with a better compliance to clinical practice guidelines, for example, biopsy before surgery, imaging, quality of initial surgery, and less reoperations (all P < 0.001). Local relapse-free survival and relapse-free survival were significantly better in patients presented to a MDTB before initiation of treatment, both in univariate and multivariate analysis. CONCLUSION: The compliance to clinical practice guidelines and relapse-free survival of sarcoma patients are significantly better when the initial treatment is guided by a pre-therapeutic specialized MDTB.

RESUMO

Background: We present a pooled analysis of predictive and prognostic values of circulating tumour cells (CTC) and circulating endothelial cells (CEC) in two prospective trials of patients with inflammatory breast cancer (IBC) treated with neoadjuvant chemotherapy combined with neoadjuvant and adjuvant bevacizumab. Patients and methods: Nonmetastatic T4d patients were enrolled in two phase II multicentre trials, evaluating bevacizumab in combination with sequential neoadjuvant chemotherapy of four cycles of FEC followed by four cycles of docetaxel in HER2-negative tumour (BEVERLY-1) or docetaxel and trastuzumab in HER2-positive tumour (BEVERLY-2). CTC and CEC were detected in 7.5 and 4 ml of blood, respectively, with the CellSearch System. Results: From October 2008 to September 2010, 152 patients were included and 137 were evaluable for CTC and CEC. At baseline, 55 patients had detectable CTC (39%). After four cycles of chemotherapy, a dramatic drop in CTC to a rate of 9% was observed (P < 0.01). Pathological complete response (pCR) rate was 40%. No correlation was found between CTC or CEC levels and pCR rate. Median follow-up was 43 months. CTC detection (≥1 CTC/7.5 ml) at baseline was associated with shorter 3-year disease-free survival (39% versus 70% for patients without CTC, P < 0.01, HR 2.80) and shorter 3-year overall survival (OS) (P < 0.01). In multivariate analysis, independent prognostic parameters for shorter survival were absence of hormonal receptors, no pCR and CTC detection at baseline. CEC level at baseline or variations during treatment had no prognostic value. Conclusion: In this pooled analysis of two prospective trials in nonmetastatic IBC, detection rate of CTC was 39% with a strong and independent prognostic value for survival. Combination of pCR after neoadjuvant treatment with no CTC detection at baseline isolated a subgroup of IBC with excellent OS (94% 3-year OS), suggesting that CTC count could be part of IBC stratification in prospective trials.

RESUMO

BACKGROUND: Bevacizumab combined with paclitaxel as first-line chemotherapy for patients with HER2-negative metastatic breast cancer (MBC) has led to mixed results in randomized trials, with an improvement in progression-free survival (PFS) but no statistically significant overall survival (OS) benefit. Real-life data could help in assessing the value of this combination. PATIENTS AND METHODS: This study aimed to describe the outcome following first-line paclitaxel with or without bevacizumab in the French Epidemiological Strategy and Medical Economics (ESME) database of MBC patients, established in 2014 by Unicancer. The primary and secondary end points were OS and PFS, respectively. RESULTS: From 2008 to 2013, 14 014 MBC patient files were identified, including 10 605 patients with a HER2-negative status. Of these, 3426 received paclitaxel and bevacizumab (2127) or paclitaxel (1299) as first-line chemotherapy. OS adjusted for major prognostic factors was significantly longer in the paclitaxel and bevacizumab group compared with paclitaxel [hazard ratio (HR) 0.672, 95% confidence interval (CI) 0.601-0.752; median survival time 27.7 versus 19.8 months]. Results were consistent in all supportive analyses (using a propensity score for adjustment and as a matching factor for nested case-control analyses) and sensitivity analyses. Similar results were observed for the adjusted PFS, favoring the combination (HR 0.739, 95% CI 0.672-0.813; 8.1 versus 6.4 months). CONCLUSIONS: In this large-scale, real-life setting, patients with HER2-negative MBC who received paclitaxel plus bevacizumab as first-line chemotherapy had a significantly better OS and PFS than those receiving paclitaxel. Despite robust methodology, real-life data are exposed to important potential biases, and therefore, results need to be treated with caution. Our data cannot therefore support extension of current use of bevacizumab in MBC.

RESUMO

BACKGROUND: Patients with high-risk gestational trophoblastic neoplasia (GTN) need multi-agent chemotherapy to be cured. The most common regimen is etoposide (E), methotrexate (M) and actinomycin D (A), alternating weekly with cyclophosphamide (C) plus vincristine (O) (EMA/CO). Cisplatin (P) is a very active drug, but it is usually restricted to second-line therapies. Herein, we report the results of a cisplatin-based therapy: APE (actinomycin D, cisplatin, and etoposide). PATIENTS AND METHODS: The efficacy and safety of APE for high-risk GTN (defined by Institut Gustave-Roussy (IGR) criteria and/or an International Federation of Gynaecology and Obstetrics (FIGO) score >6) are reported. Patients with brain metastasis or placental-site trophoblastic tumour were excluded. RESULTS: Between 1985 and 2013, 95 patients were treated with APE for high-risk GTN: 59 patients as first-line, 36 as ⩾ 2nd-line therapy. There was 94.7% complete remission, though five patients relapsed. One patient died from GTN after multiple lines of chemotherapy. The five-year overall survival rate (median follow-up 5.7 years) was 97% (95% confidence interval (CI): 91-99%). No death from toxicity occurred. Long-term, six grade-1 neuro-toxicities, three grade-1 and two grade-2 oto-toxicities, and one grade-1 renal toxicity were recorded. One patient developed AML-M4 after APE and EMA/CO. Thirty-four of 35 women, who wished to become pregnant, succeeded and all had at least one live birth. CONCLUSION: With a 97% long-term overall survival rate, limited long-term toxicity, and an excellent reproductive outcome, APE could be regarded as an alternative option to EMA/CO as a standard therapy for high-risk GTN.

RESUMO

BACKGROUND: At 42.5 months of median follow-up, PHARE failed to show that 6 was non-inferior to 12 months of adjuvant trastuzumab. From the results of PHARE, questions remain regarding whether the magnitude of benefit derived from 1 year is sufficient to justify its systematic use for different patient subgroups. METHODS: Treatment effects were evaluated according to various tumour characteristics, and the multivariate Cox proportional hazards regression models were carried out on metastases-free survival (MFS) in the 12 months control arm. A prognostic score was defined providing the identification of patient categories with similar risks. The 6-month arm was used as a validation set in order to test for heterogeneity. This study is registered at clinicaltrials.gov, number NCT00381901. RESULTS: A total of 261 metastatic events were observed and four prognostic groups were defined: very low, low, intermediate and high risk in the 12-month arm. The corresponding 3-year MFS rates were 98.3%, 95.8%, 90.4% and 78.4% in the four prognostic groups, respectively. In the 6-month arm, the 3-year MFS rates were 98.3%, 94.2%, 85.7% and 74.8% in the four prognostic groups, respectively. CONCLUSION: In the very low-risk group, the potential absolute benefit of standard duration of trastuzumab was small enough to indicate that optimal standard treatment might be clinically questionable. On the other hand, the 3-year metastasis occurrence rates strongly support the need for a search of a more efficient treatment in the low-, intermediate- and high-risk groups.

RESUMO

BACKGROUND: Mandibular osteosarcomas (MOS) mostly affect young adults. Their treatment is extrapolated from that of extragnathic osteosarcomas. MATERIAL AND METHODS: A retrospective multicooperative group study was conducted to determine the impact of chemotherapy, adjuvant radiation therapy and surgery on outcomes and to identify prognostic factors. This ethical committee-approved study included a centralized review of histology slides and operative reports. RESULTS: Of 111 patients, 58.6% were male, median age 35 years (13%, ≤18 years). Histology was osteoblastic, chondroblastic, fibroblastic, conventional not otherwise specified and others in 39.6%, 30.6%, 8.1%, 12.6% and 8.0%, respectively. Pathological World Health Organisation grades were low, intermediate and high grade in 6.4%, 11.8% and 81.8%, respectively. Surgery was carried out for 94.5% of patients. Neoadjuvant chemotherapy (mixed protocols) was carried out in 93.1% of patients. Postoperative chemotherapy and radiotherapy were carried out in 54.7% and 23.8%, respectively. Median follow-up was 59.6 months (range). Five-year local control, metastasis-free, disease-free and overall survival rates were 64.6%, 68.9%, 53.2% and 69.2%, respectively. Survival was significantly associated with age, tumor size and surgery. Wide surgery with clear margins and free flap reconstruction was the strongest prognostic factor. Neoadjuvant chemotherapy improved disease-free and metastatic-free survival and increased clear margins rates from 50% to 68%. Intermediate grades behaved like high grades in terms of metastatic-free and disease-free survival. CONCLUSION: This homogeneous series is the largest to date and emphasizes the major impact of clear margins and multidisciplinary management. Neoadjuvant chemotherapy improves disease-free survival and should be recommended for both high and intermediate grade MOS.

RESUMO

BACKGROUND: There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS. METHODS: Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m² d1, ifosfamide 3 g/m²/day d1-2, cisplatin 75 mg/m² d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment. RESULTS: Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41). CONCLUSION: API adjuvant CT statistically increases the 3 year-DFS of patients with US.

RESUMO

PURPOSE: This study aims to evaluate the sensibility and specificity of MRI in the detection and size measuring of residual breast cancer in patients treated with neoadjuvant chemotherapy before surgery. PATIENTS AND METHODS: This is a retrospective study of 32 women, who underwent breast MRI before and after neoadjuvant treatment. MRI has been confronted to surgical pathology results. RESULTS: The sensibility of MRI to assess pathologic Complete Response (no invasive residual tumor) was excellent (100%) but the specificity was low (55,5%). There was no false negative case and four false positive cases (Two ductal carcinomas in situ and two scars-like fibrosis). When MRI outcomes were compared with the presence or absence of invasive or in situ residual carcinoma, only one false negative case was noticed (one "in situ" residual tumor). The correlation between tumor size measured by MRI and histopathology was low (r=0,32). Underestimations of tumor size were due to non-continuous tumor regression or invasive lobular carcinoma or association of invasive carcinoma and intra ductal breast cancer. Over estimations of tumor size were due to chemotherapy-induced changes. CONCLUSION: MRI is a sensitive but poorly specific method to assess the pathological complete response after neoadjuvant chemotherapy. Estimation of tumor size and detection of isolated residual in situ carcinoma are fare. Therefore, surgical intervention remains necessary whatever the MRI outcomes.

RESUMO

BACKGROUND: Participants are showing great interest these days in obtaining the results of clinical trials. The aim of this study was to assess patients' uptake and understanding of the results of the trial in which they have participated and the impact of a letter offering patients the possibility of consulting the trial results on a specific website. METHODS: Breast cancer patients participating in a trial on the efficacy of Trastuzumab were randomly subdivided into an Internet group (who received the letter of invitation) and a control group (who did not receive it). Among 115 HER2-positive women from 21 centres, 107 (93%) answered a self-administered questionnaire. RESULTS: Most of the patients in both groups had access to the Internet (72.0%). The majority (97.2%) stated that receiving information about the trial results would be useful, and the oncologist was the most frequently preferred information provider. The Internet group's declared uptake of the trial results was only slightly higher (47.1% vs 33.9%; P=0.166); however, they understood the results significantly more accurately (18.8% vs 5.6%; P=0.039). INTERPRETATION: Although Internet was not the respondents' preferred source of information, the possibility of using this source slightly increased the uptake and understanding of the results.

RESUMO

Breast cancer (BC) is the first female cancer in France, accounting for 49,240 new cases in 2004. Approximately 80% of those tumors have positive hormone receptors (HR). Tamoxifen was used in four chemoprevention randomized trials, as well as another SERM (Selective Estrogen Receptor Modulation), raloxifen. This review analyses the updated results of these trials. All trials have shown that the risk of developing HR positive BC was reduced by tamoxifen or raloxifen, but without impact on HR negative BC and overall survival. Moreover, several unfavorable side effects (thrombo-embolic accidents and uterine cancers) have been observed. A new assessment of BC risk factors seems necessary, including not only family history and some histopathological abnormalities (e.g. atypical hyperplasia), but also new elements such as high bone and breast density and thoracic irradiation at young age (Hodgkin's disease). Indeed, tamoxifen efficacy seems optimal in very "high-risk" women. Therefore, the creation of a new and most comprehensive "risk model" is necessary as well as a tailored SERM use (maybe with other compounds), in order to optimize results and reduce potential side effects.

RESUMO

The objective is to investigate the activity and toxicity of bleomycin, etoposide, and cisplatin (BEP) regimen in ovarian granulosa cell tumors (OGCTs). Twenty consecutive patients with initial metastatic (5 patients) or recurrent (15 patients) OGCT were treated; BEP regimen: B: 30 mg intravenously or intramurally on days 1, 8, and 15; E: 100 mg/m2/day on days 1-5; and P: 20 mg/m2/day on days 1-5. Median age: 42 years (range: 17-60); median follow-up: 45 months (range: 3-112). The overall response rate is 90% (nine clinical complete response [CR], nine clinical partial response) with a median duration of 24 months (range: 4-77). A second-look laparotomy performed in 11 patients showed a pathologic CR in 7 cases and microscopic disease in 1 case. Seven patients remain free of disease (at 4-84 months); 11 patients relapsed (median: 24 months, range: 13-58), 12 patients are still alive, and 9 patients are without disease (2 patients in second CR). At 4 years, overall survival and event-free survival are respectively 58% and 30%. Toxicity is evaluable for 19 patients (48 cycles). A grade 4 neutropenia occurred in 15% of cycles (in seven patients) with a febrile neutropenia in four patients. Five patients experienced a low bleomycin pulmonary toxicity. BEP regimen appears to be an active regimen for OGCT in first-line chemotherapy.

RESUMO

BACKGROUND: The aim of this study is to determine feasibility and efficacy of the combination regimen oxaliplatin and paclitaxel in patients with cisplatin (CDDP)-refractory germ-cell tumors (GCT). PATIENTS AND METHODS: Patients with either a cisplatin absolute-refractory GCT defined as progressive disease (PD) during or within 1 month of CDDP administration or with a poor prognosis relapse, defined as PD between the second and the sixth month after CDDP administration, were treated with a combination of oxaliplatin (130 mg/m(2)) and paclitaxel (175 mg/m(2)) administered every 21 days. Primary end point was efficacy. RESULTS: Twenty-seven patients were included. Patients were pretreated with a median of two lines of cisplatin-based chemotherapy (range 1-5). Sixteen patients were absolute refractory. Five patients had relapsed after high-dose chemotherapy plus stem-cell support. There were no complete responses but there was one marker-positive partial response and nine disease stabilization (34, 6%). After a median follow-up of 65 months, two patients are disease-free survivors. Main toxicity was leucocytopenia grade 3/4 in 30% of the patients. CONCLUSION: Combination chemotherapy with oxaliplatin and paclitaxel is feasible with acceptable toxicity and may be effective if combined with additional treatment in patients with CDDP-refractory GCT.

RESUMO

BACKGROUND: Ovarian yolk sac tumor (YST) is a very rare malignancy arising in young women. Chemotherapy has dramatically improved the prognosis. Current treatment consists of surgery followed by bleomycin, etoposide, and cisplatin (BEP) chemotherapy. However, given the rarity of this tumor, ovarian YST-specific survival and outcome after such treatment are not precisely known. PATIENTS AND METHODS: This report concerns prospectively recorded cases that were either treated at Institut Gustave Roussy (Villejuif, France) or referred there for advice about therapy. From 1990 to 2006, 52 patients underwent surgery followed by BEP chemotherapy. Data on patient characteristics, treatment, survival, and fertility outcome were analyzed to assess treatment efficacy and gonadal toxicity after achieving a complete remission. RESULTS: Thirty-five patients had stage I/II tumors while 17 patients presented with stage III/IV disease. With a median follow-up of 68 months, the overall 5-year survival and disease-free survival rates were 94% and 90%, respectively. Forty-one women underwent fertility-sparing surgery. Pregnancy was achieved in 12 of 16 (75%) women who attempted conception. Overall, 19 pregnancies have been recorded. CONCLUSIONS: BEP chemotherapy following fertility-sparing surgery is a very effective treatment of ovarian YSTs. Most of the patients who attempt conception after complete remission will have children.

RESUMO

BACKGROUND: The evaluation of first-line intensive combination therapy in small cell carcinoma of the ovary (SCCO). PATIENTS AND METHODS: Debulking surgery; four to six cycles of chemotherapy with cisplatin (P) 80 mg/m(2) day 1, adriamycin (A) 40 mg/m(2) day 1, vepeside (V) 75 mg/m(2)/day days 1-3, cyclophosphamide (EP) 300 mg/m(2)/day days 1-3, every 3 weeks and granulocyte colony-stimulating factor with, in case of a complete remission, high-dose chemotherapy with carboplatin, vepeside, cyclophosphamide and stem-cell support. RESULTS: Twenty-seven patients (median age 25 years); International Federation of Gynecology and Obstetrics stage: five I, four IIC, 17 IIIC-IV and one unknown. Twenty patients underwent complete surgery. Eight patients progressed under chemotherapy. Among 18 patients in complete response (CR), 10 received high-dose chemotherapy (CT) (three stem-cell collection failures, two protocol violations, two disease progression and one refusal). The main grade 3-4 toxic effects were hematologic. There were eight relapses among the 18 CR, four of which were pelvic alone. Among the 27 patients, 13 died and 10 patients are in CR1, three in CR2. The median follow-up is 37 months (8-166) and the median duration of the 18 CR is 30 months (5-111). Overall survival at 1 and 3 years is 58% [confidence interval (CI) 40% to 75%] and 49% (CI 30% to 67%). CONCLUSIONS: Initial dose-intensive therapy achieves interesting overall survival in SCCO.

RESUMO

The aim of the study was to compare our reference adjuvant chemotherapy, FEC100 (fluorouracil 500 mg m(-2), epirubicin 100 mg m(-2) and cyclophosphamide 500 mg m(-2), six cycles every 21 days), to an epirubicin-vinorelbine (Epi-Vnr) combination for early, poor-prognosis breast cancer patients. Patients (482) were randomised to receive FEC100, or Epi-Vnr (epirubicin 50 mg m(-2) day 1 and vinorelbine 25 mg m(-2), days 1 and 8, six cycles every 21 days). The 7-year disease-free survival rates were 59.4 and 58.8%, respectively (P=0.47). The relative dose intensity of planned epirubicin doses was 89.1% with FEC100 and 88.9% with Epi-Vnr. There were significantly more grades 3-4 neutropenia (P=0.009) with Epi-Vnr, and significantly more nausea-vomiting (P<0.0001), stomatitis (P=0.0007) and alopecia (P<0.0001) with FEC100. No cases of congestive heart failure were reported, whereas four decreases in left ventricular ejection fraction occurred after FEC100 and five after Epi-Vnr. One case of acute myeloblastic leukaemia was registered in the FEC100 arm. After 7 years of follow-up, there was no difference between treatment arms. Epi-Vnr regimen provided a good efficacy in such poor-prognosis breast cancer patients, and could be an alternative to FEC100, taking into account respective safety profiles of both regimens.

RESUMO

BACKGROUND: Docetaxel (Taxotere)-based regimens are the new standard therapy in advanced hormone-refractory prostate cancer (HRPC). A synergistic activity has been shown with docetaxel in combination with estramustine in vitro; however, the benefit of this combination remains controversial in clinical practice. We assessed the activity and safety of docetaxel alone and docetaxel-estramustine in HRPC. PATIENTS AND METHODS: Patients (n = 92) with metastatic HRPC and rising prostate-specific antigen (PSA) while receiving androgen suppression were randomized to 3-weekly treatment with either docetaxel 75 mg/m(2), day 1 (D), or docetaxel 70 mg/m(2), day 2, plus oral estramustine 280 mg twice daily, days 1-5 (DE). RESULTS: Ninety-one patients were treated (DE 47, D 44). A PSA response occurred in 68% (primary endpoint met) and 30% of patients, respectively. Median PSA response duration was 6.0 months in both groups. Median time to progression was 5.7 and 2.9 months, and median survival was 19.3 and 17.8 months in the DE and D arms, respectively. Hematologic and non-hematologic toxic effects were mild and similar in both arms. One patient in each group withdrew due to toxicity. Quality of life was similar in both groups. CONCLUSION: Combining estramustine with docetaxel in this schedule is an active and well-tolerated treatment option in HRPC.

RESUMO

BACKGROUND: High cure rates are expected in good-risk metastatic nonseminomatous germ-cell tumor (NSGCT) patients with bleomycin, etoposide and cisplatin. PATIENTS AND METHODS: Patients received either three cycles of BE500P or four cycles of E500P every 3 weeks. Disease was defined according to the Institut Gustave Roussy prognostic model. Patients were retrospectively assigned into the International Germ Cell Cancer Collaborative Group (IGCCCG) classification. A sample size of 250 patients was necessary for an expected favorable response rate (primary end point) of 90% and not more than a 10% difference between the two arms. RESULTS: Among 257 assessable patients, 124 and 122 patients achieved a favorable response in the 3BE500P and 4E500P arms, respectively (P = 0.34). Median follow-up was 53 months. The 4-year event-free survival rates were 91% and 86%, respectively (P = 0.135). The 4-year overall survival rates were not significantly different [five deaths versus 12 deaths, respectively (P = 0.096)]. Similar nonsignificant trends were observed in good IGCCCG prognosis patients. CONCLUSIONS: Both regimens produced similar results in terms of favorable response rates. As the trial was underpowered for survival analyses, conclusive data would require a larger randomized trial. Unless such a study is done, 3BE500P is the treatment of choice for metastatic NSGCT patients.
