RESUMEN

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.

RESUMEN

BACKGROUND: In 2008, a study of the characteristics of hospitalised patients led to the development of a prognostic tool that distinguished three populations with significantly different 2-month survival rates. The goal of our study aimed at validating prospectively this prognostic tool in outpatients treated for cancer in terminal stage, based on four factors: performance status (ECOG) (PS), number of metastatic sites, serum albumin and lactate dehydrogenase. PATIENTS AND METHODS: PRONOPALL is a multicentre study of current care. About 302 adult patients who met one or more of the following criteria: life expectancy under 6 months, performance status ≥ 2 and disease progression during the previous chemotherapy regimen were included across 16 institutions between October 2009 and October 2010. Afterwards, in order to validate the prognostic tool, the score was ciphered and correlated to patient survival. RESULTS: Totally 262 patients (87%) were evaluable (27 patients excluded and 13 unknown score). Median age was 66 years [37-88], and women accounted for 59%. ECOG PS 0-1 (46%), PS 2 (37%) and PS 3-4 (17%). The primary tumours were: breast (29%), colorectal (28%), lung (13%), pancreas (12%), ovary (11%) and other (8%). About 32% of patients presented one metastatic site, 35% had two and 31% had more than two. The median lactate dehydrogenase level was 398 IU/l [118-4314]; median serum albumin was 35 g/l [13-54]. According to the PRONOPALL prognostic tool, the 2-month survival rate was 92% and the median survival rate was 301 days [209-348] for the 130 patients in population C, 66% and 79 days [71-114] for the 111 patients in population B, and 24% and 35 days for [14-56] the 21 patients in population A. These three populations survival were statistically different (P <0.0001). CONCLUSION: PRONOPALL study confirms the three prognostic profiles defined by the combination of four factors. This PRONOPALL score is a useful decision-making tool in daily practice.

RESUMEN

BACKGROUND: Inflammatory breast cancer (IBC) is a rare and aggressive disease requiring a multimodal treatment. We evaluated the benefit of adding docetaxel-5-fluorouracil (D-5FU) regimen after preoperative dose-intense (DI) epirubicin-cyclophosphamide (EC) and locoregional treatment in IBC patients. PATIENTS AND METHODS: PEGASE 07 was a national randomized phase III open-label study involving 14 hospitals in France. Women with nonmetastatic IBC were eligible and randomly assigned to receive either four cycles of DI EC (E 150 mg/m(2) and C 4000 mg/m(2) every 3 weeks with repeated hematopoietic stem cell support), then mastectomy with axillary lymph node dissection, and radiotherapy (arm A) or the same treatment followed by four cycles of D-5FU (D 85 mg/m(2), day 1 and 5FU 750 mg/m(2)/day continuous infusion, days 1-5 every 3 weeks) administered postradiotherapy (arm B). Patients with hormone receptor-positive tumors received hormonal therapy. Disease-free survival (DFS) was the primary end point. Secondary end points included tolerance, pathological complete response (pCR) rate, and overall survival (OS). RESULTS: Between January 2001 and May 2005, 174 patients were enrolled and treated (87 in each arm). Median follow-up was similar in both arms: 59.6 months [95% confidence interval (CI) 58.4-60.3] in arm A and 60.5 months (95% CI 58.3-61.4) in arm B. The estimated 5-year DFS rates were not different: 55% (95% CI 43.9-64.7) in arm A and 55.5% (95% CI 44.3-65.3) in arm B [hazard ratio (HR) = 0.94 (0.61-1.48); P = 0.81]. Identical results were observed for 5-year OS: 70.2% (95% CI 59.1-78.8) in arm A and 70% (95% CI 58.8-78.7) in arm B [HR = 0.93 (0.55-1.60); P = 0.814]. Following DI EC induction, in-breast and global (breast plus nodes) pCR were 28.9% and 20.1%, respectively. Estrogen receptor and pCR status were independently associated with survival. CONCLUSION: The addition of D-5FU after preoperative DI EC and standard local therapy did not improve DFS in IBC. CLINICAL TRIAL NUMBER: ClinicalTrials.gov identifier: NCT02324088.

RESUMEN

BACKGROUND: High-dose chemotherapy (HDCT) is an effective salvage treatment of germ-cell tumors (GCTs) patients. In the first salvage setting, 30%-70% of patients may achieve durable remissions. Even when HDCT is administered as subsequent salvage treatment, up to 20% of patients may still be definitively cured. However, patients with refractory/relapsed disease still have a very poor long-term prognosis, requiring earlier intervention of HDCT. PATIENTS AND METHODS: This phase II trial was addressed to nonrefractory patients failing Cisplatin-based chemotherapy. Inclusion criteria included seminomatous GCT in relapse after two lines of chemotherapy, nonseminomatous GCT in relapse after first or second lines, partial remission after first line, primary mediastinal GCT in first relapse. Patients received two cycles combining Epirubicin and Paclitaxel (Epi-Tax), followed by three consecutive HDCT, one using a Paclitaxel/Thiotepa (Thio-Tax) association and two using the 5-day Ifosfamide-Carboplatin-Etoposide regimen. The main objective was to determine the complete response rate. RESULTS: Forty-five patients were included between September 2004 and December 2007: 44 received the first HDCT cycle, 39 two HDCT cycles, 29 could receive the whole protocol. Sixteen patients did not receive the entire protocol, including eight (17.7%) for toxic side-effects. Two patients (4.4%) died of toxicities, and 17 (37.7%) of disease progression. With a median follow-up time of 26 months (range, 4-51), the final overall response rate was 48.8% (including a complete response rate of 15.5% and a partial response/negative serum markers rate of 26.6%) in an intent-to-treat analysis. The median progression-free survival (PFS) and overall survival (OS) times were 22 months [95% confidence interval (CI) 2-not reached] and 32 months (95% CI 4-49), respectively. The 2-year PFS was a plateau setup at 50% (95% CI 32-67) and the 2-year OS was 66% (95% CI 44-81). CONCLUSION: The TAXIF II protocol was effective in nonrefractory GCT patients failing Cisplatin-based chemotherapy. The toxic death rate remained acceptable in the field of HDCT regimens. TRIAL REGISTRATION NUMBER: NCT00231582.

RESUMEN

BACKGROUND: The standard treatment of patients with metastatic germ-cell tumor (GCT) relapsing after first-line chemotherapy is based on a cisplatin and ifosfamide-containing three-drug regimen, which usually yields a complete response (CR) rate <50%. As gemcitabine consistently displayed activity in patients with advanced GCT and as synergy with cisplatin was reported, we integrated this drug into the salvage triplet regimen and assessed its activity in this phase II study. PATIENTS AND METHODS: The GIP regimen consisted in gemcitabine 1000 mg/m(2) day 1 and 5, ifosfamide 1200 mg/m(2)/day day 1-5, cisplatin 20 mg/m(2)/day day 1-5, and granulocyte colony-stimulating factor 263 µg/day day 7-15, repeated every 3 weeks for four cycles. Eligibility criteria were that patients had favorable prognostic factors to conventional-dose salvage chemotherapy including a testis primary tumor and a previous CR to first-line chemotherapy for metastatic disease. The primary end point was the CR rate and a two-stage Simon design was used. RESULTS: Thirty-seven patients were accrued and 29 (78%) achieved a favorable response, including a CR in 20 (54%) and a partial response with normalization of tumor markers (PRm-) in 9 (24%). With a median follow-up of 53 months (13-81), the 2-year overall survival rate is 73% (57%-84%) and the continuous progression-free survival rate is 51% (35%-66%). Myelosuppression was the main toxicity including febrile neutropenia in 8 (22%) patients and 18 (50%) cases required platelet infusion. No grade 3 and 4 peripheral neurotoxicity or renal toxicity occurred. Two patients died of treatment-related toxicity, one of them with cancer progression. CONCLUSION: In a multicenter context, four cycles of the GIP regimen achieved a high CR rate in patients with relapsed testicular GCT. The GIP regimen avoided severe neurotoxicity and yielded a high survival rate. CLINICAL TRIAL NUMBER: NCT00127049.

RESUMEN

Brain metastases (BM) can affect up to 45 % of a high-risk breast cancer (BC) population. Liposomal doxorubicin (LD)-based chemotherapy has demonstrated efficacy in the treatment of BC and LD crosses the blood-brain barrier. The aim of this retrospective study is to evaluate the efficacy of the LD-cyclophosphamide (CTX) combination in BM related to BC. Patients diagnosed with BM related to BC and treated with the LD-CTX combination were eligible. BM objective response rate (BM-ORR), BM disease control rate (BM-DCR), BM progression-free survival, overall survival (OS) and safety were analyzed. 29 patients were eligible. The median time from metastatic diagnosis to brain involvement was 12 months. BM was more frequently observed in HER2+ patients. On average, three courses of chemotherapy were administered without grade 3-4 limiting adverse events. After three cycles, BM-ORR and BM-DCR were 41.4 and 58.6 % respectively versus 50 and 62.5 % when no prior radiotherapy was administered. From BM diagnosis, OS was 23 months. A high BM-ORR is observed with the LD-CTX combination in patients with BM related to BC. This is an attractive therapeutic option for these patients, especially when no prior whole brain radiotherapy has been administered.

RESUMEN

BACKGROUND: Widening access to medical students from diverse educational backgrounds is a global educational mandate. The impact, on students' generic learning skills profiles, of development programmes designed for students at risk of attrition is unknown. AIMS: This study investigated the impact of a 12-month Intervention Programme (IP) on the generic learning skills profile of academically-at-risk students who, after failing at the end of the first semester, completed the IP before entering the second semester of a conventional medical training programme. METHODS: This prospective study surveyed medical students admitted in 2009 and 2010, on entry and on completion of first year, on their reported practice and confidence in information handling, managing own learning, technical and numeracy, computer, organisational and presentation skills. RESULTS: Of 414 first year students, 80 (19%) entered the IP. Levels of practice and confidence for five of the six skills categories were significantly poorer at entry for IP students compared to conventional stream students. In four categories these differences were no longer statistically significant after students had completed the IP; 62 IP students (77.5%) progressed to second year. CONCLUSIONS: A 12-month development programme, the IP, effectively addressed generic learning skills deficiencies present in academically-at-risk students entering medical school.

RESUMEN

OBJECTIVE: To evaluate the outcomes following targeted therapies in the management of metastatic renal cell carcinoma (mRCC), through the study of overall survival (OS) and progression-free (PFS). PATIENTS AND METHODS: We retrospectively included 78 patients treated with targeted therapies for mRCC at the Paul Papin Cancer Institute from 2004 to 2009. Overall survival (OS), progression free survival (PFS), response to treatment, occurrence of grade III and IV side effects, were analyzed following first and second line treatments. RESULTS: Median follow-up was 33 months [5-236], and 41 patients died (52.6%). Median OS was 36 months [95% CI 29-43]. The median PFS was 14 months [95% CI 6.71-21.29] for sunitinib, 38 months [95% CI 11.41-64.59] for bevacizumab with interferon (IFN), and 8 months [95% CI 0-17.03] for IFN alone. A partial reduction, stabilization or increase in tumor size was observed for 19.2%, 47.4% and 25.6% of cases. A second line treatment was given for 53 patients. They received either sunitinib (n=20, 37.8%), bevacizumab with IFN (n=7, 13.2%), sorafenib (n=17, 32.2%), temsirolimus (n=3, 5.6%) or other molecules (n=6 11.2%). Grade III or IV side effects were observed for 14.1%, 28.3% and 18.2% of the patients following first, second and third line treatment, respectively. CONCLUSION: Outcomes of targeted therapies in our center upheld the literature data. These therapies allow a benefit survival versus immunotherapy, with sometimes large side-effect.

RESUMEN

BACKGROUND: Although the taxanes paclitaxel and docetaxel are among the most active agents for the treatment of a wide range of cancers, tumours often develop resistance to these treatments. Cabazitaxel is a novel taxane active in both preclinical models of chemotherapy-sensitive and -resistant human tumours and patients with advanced prostate cancer that progressed following docetaxel treatment. AIM: To establish the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of cabazitaxel. PATIENTS AND METHODS: Cabazitaxel was administered every 3 weeks to patients with advanced solid tumours. The design allowed intrapatient dose escalation. The primary objective was to determine the MTD. Secondary objectives were to describe the safety profile, establish an appropriate dose, determine the pharmacokinetic (PK) profile of cabazitaxel, and assess antitumour activity. RESULTS: Twenty-one patients were recruited. The MTD was reached at 30 mg/m(2), at which three of five patients experienced haematologic DLTs during the first cycle. DLTs during subsequent cycles were mainly haematologic and reported at 25 and 30 mg/m(2) dosing levels. Nail disorders and severe alopecia were not reported, and neurotoxicity, fluid retention and hypersensitivity were mild and infrequent. Cabazitaxel demonstrated linear PK, a triphasic elimination profile, with a long half-life and high clearance. Of the 19 patients evaluable for response, one unconfirmed partial response and six occurrences of stable disease were reported. CONCLUSIONS: The 25mg/m(2) dose of cabazitaxel was recommended for use in future clinical studies. In this study, cabazitaxel had an acceptable tolerability profile and activity in cervical, colorectal, endometrial and lung cancers.

RESUMEN

BACKGROUND: There are limited data on treatment outcomes in the growing population of elderly patients with locally recurrent/metastatic breast cancer (LR/mBC). To gain information on first-line bevacizumab combined with chemotherapy in the elderly, we analyzed data from the ATHENA trial in routine oncology practice. PATIENTS AND METHODS: Patients with human epidermal growth factor receptor-2-negative LR/mBC received first-line bevacizumab with standard chemotherapy until disease progression, unacceptable toxicity, or physician/patient decision. We carried out a subgroup analysis of safety and efficacy in patients aged≥70 years. Possible correlations between tolerability and baseline comorbidities or Eastern Cooperative Oncology Group status were explored. RESULTS: Bevacizumab was combined with single-agent paclitaxel in 46% of older patients. Only hypertension and proteinuria were more common in older than in younger patients (grade≥3 hypertension: 6.9% versus 4.2%, respectively; grade≥3 proteinuria: 4.0% versus 1.5%, respectively). Grade≥3 arterial/venous thromboembolism occurred in 2.9% versus 3.3%, respectively. Further analysis revealed no relationship between baseline presence and severity of hypertension and risk of developing hypertension during bevacizumab-containing therapy. Median time to progression was 10.4 months in patients aged≥70 years. CONCLUSIONS: These findings suggest that bevacizumab-containing therapy is tolerable and active in patients aged≥70 years. Hypertension was more common than in younger patients but was manageable. We find no evidence precluding the use of bevacizumab in older patients, including those with hypertension, although age may influence chemotherapy choice.

RESUMEN

BACKGROUND: A dose-dense strategy has been considered to improve results of adjuvant chemotherapy for breast cancer. This randomised phase II trial investigated the feasibility of this approach with sequential anthracyclines and taxanes-based chemotherapy. METHODS: Patients with high-risk node-positive breast cancer were treated with three cycles of fluorouracil 500 mg m(-2), epirubicin 100 mg m(-2), cyclophosphamide 500 mg m(-2) (FEC 100) followed by three cycles of docetaxel 100 mg m(-2) delivered at 2-weekly intervals supported by primary prophylaxis with filgrastim. All patients were randomised to either uninterrupted treatment (arm A) or to have a 2-week additional period of rest between the FEC and docetaxel (arm B). The primary endpoint was the rate of success of chemotherapy delivery. Using a two-stage Fleming design, 120 patients were required with one interim analysis. RESULTS: In March 2005, enrolment was stopped into arm A after the observation of severe skin toxicities. Following the planned interim analysis, the study was closed because of the high rate of grade 3/4 skin toxicities in both arms (arm A: 32.4% and arm B: 18.9%). CONCLUSION: Sequential dose-dense FEC 100 followed by docetaxel 100 mg m(-2) is not feasible. Feasibility still depends largely on several factors including the choice of drugs, dosage and sequence of administration.

RESUMEN

Failure criteria of antiangiogenic treatment that must make envisage a change of molecule are still difficult to define. Concerning the evaluation of the response, if the RECIST criteria seem to be limited, several other tools of evaluation (clinical, radiological or biological tools) can be interesting. It is the case of contrast-enhanced ultra-sonography, but a precise definition of functional parameters should be defined and a standardization of the technique is necessary. Side effects do not translate necessarily a treatment failure. They must be estimated by taking into account the frequency of some of symptoms. Asthenia is noticed in more than 50% of the patients ; it is however necessary to exclude another aetiology, in particular iatrogenic hypothyroidism.

RESUMEN

BACKGROUND: We investigated whether circulating tumor cells (CTCs) and circulating endothelial cells (CECs) predict clinical outcome of first-line chemotherapy combined with bevacizumab in metastatic breast cancer patients. PATIENTS AND METHODS: In a French substudy of the MO19391 trial, CTC and CEC counts (CellSearch system) at baseline and changes after two cycles of treatment were correlated with time to progression (TtP). RESULTS: CTC and CEC levels were not correlated in the 67 patients included. At baseline, CTC positivity was a significant prognostic marker for TtP at a threshold of 3 CTC/7.5 ml (P < 0.05) but not at 5 CTC/7.5 ml (P = 0.09). Baseline CEC levels (median 17 CEC/4 ml, range 1-769) were associated with age > or =45 years (P = 0.01), elevated lactate dehydrogenase (P < 0.01) and not with TtP at any threshold. Changes of CTC count during treatment were not a surrogate of TtP, with any of the model tested (threshold based or relative decrease in percent). However, increase in CEC count was associated with improved TtP, at the threshold of 20 CEC/4 ml (P < 0.01). CONCLUSION: Bevacizumab combined with first-line chemotherapy may modify the predictive value of CTC during treatment possibly due to impaired tumor cells intravasation through vessels endothelium. Variations in CEC levels appear to be a promising early surrogate marker of TtP under antiangiogenic treatment.

RESUMEN

OBJECTIVES: The aim of this phase II study was to assess the benefits of a weekly administration of topotecan and gemcitabine in patients with ovarian carcinoma having relapsed after platinum/taxane-based first-line chemotherapy. METHODS: Seventy-seven patients with progression of disease /=2 cycles administered). The only major severe toxicity was neutropenia grades 3 (17%) and 4 (6%). Approximately 60% of the patients received the complete schedule of treatment, dose interruptions/delays being mainly due to moderate thrombocytopenia or neutropenia. The objective response rate was 14%, the values for patients having relapsed within 6 (n=30) and 6-12 (n=36) months being 7% and 20%, respectively. Median durations of response were 4.9 and 6.4 months and clinical benefit rates including stabilizations reached 63% and 69% in patients having relapsed within 6 or 6-12 months, respectively. Corresponding median overall survival was 7.5 and 15.6 months. Symptoms and pain were reduced in 64% and 39% of the patients concerned, respectively. CONCLUSION: In early relapse ovarian cancer, weekly combination of gemcitabine and topotecan has a modest objective response rate. However, a high proportion of patients experienced stable disease and symptom control leading to acceptable quality of life.

RESUMEN

BACKGROUND: In patients with untreated metastatic renal cell carcinoma (mRCC), progression-free survival (PFS) was longer with bevacizumab + interferon (IFN)-alpha than IFN + placebo (AVOREN trial). In this hypothesis-generating study, subgroup analysis was carried out to determine the effect of IFN dose reduction. PATIENTS AND METHODS: A total of 649 patients received IFN 9 MIU s.c. three times weekly plus bevacizumab 10 mg/kg or placebo every 2 weeks until disease progression. The IFN dose was reduced to 6 or 3 MIU with the development of IFN-attributed toxicity. Differences between treatment arms in PFS, response rate and tolerability were analysed in the reduced-dose group. RESULTS: IFN dose was reduced in 131 patients in the bevacizumab + IFN arm and 97 patients in the IFN + placebo arm during the trial. PFS rates in the bevacizumab + reduced-dose IFN group were comparable with the total population (Kaplan-Meier estimates of event-free rate at 1 year: 0.524 versus 0.427). Bevacizumab + reduced-dose IFN was well tolerated, with substantial decreases in the rate of adverse events following dose reduction. CONCLUSION: This retrospective subgroup analysis suggests that the dose of IFN can be reduced to manage side-effects while maintaining efficacy in patients with mRCC receiving bevacizumab + IFN.

RESUMEN

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.

RESUMEN

BACKGROUND: Morbidity of the shoulder after breast cancer is a well-known phenomenon. MRI studies have shown muscle morbidity in cervical cancer and prostate cancer. In breast cancer clinical observations and patient reports include muscle morbidity in a number of muscles acting at the shoulder. Several of these muscles lie in the field of surgery and radiotherapy. Timed interaction between muscles that stabilise the shoulder and those acting as prime movers is essential to achieve a smooth scapulohumeral rthythm during functional elevation of the arm. METHOD: CROSS-SECTIONAL STUDY: Seventy-four women treated for unilateral carcinoma of the breast were included in the study. All patients filled out the Shoulder Pain and Disability Index (SPADI). EMG activity of four muscles was recorded during scaption on the affected and unaffected side. Muscle cross sectional area and signal intensity was determined from MRI scans. The association between EMG and covariates was determined using multiple linear regression techniques. RESULTS: Three of the 4 muscles on the affected side demonstrated significantly less EMG activity, particularly when lowering the arm. Upper trapezius demonstrated the greatest loss in activity. Decreased activity in both upper trapezius and rhomboid were significantly associated with an increase in SPADI score and increased time since surgery. Pectoralis major and minor were significantly smaller on the affected side. CONCLUSION: Muscles affected in the long term are the muscles associated with pain and disability yet are not in the direct field of surgery or radiotherapy. Primary muscle shortening and secondary loss of muscle activity may be producing a movement disorder similar to the 'Dropped Shoulder Syndrome'. Exercise programmes should aim not only for range of movement but also for posture correction and education of potential long-term effects.

RESUMEN

PURPOSE: Intravenous (i.v.) vinorelbine (VRL) generally given on days 1 and 8 of an every three-week cycle in combination with paclitaxel (PTX) is an effective option for the treatment of metastatic breast cancer (MBC). In an effort to improve both patient and chemotherapy unit convenience, oral VRL was used at equivalent doses of i.v. VRL. PATIENTS AND METHODS: The maximal tolerated dose (MTD) was determined during the first cycle of oral VRL given on days 1 and 8 or 15 and PTX infused over 3 h on day 1 every 3 weeks, maximum of 6 cycles. The dose of oral VRL was escalated from 60 to 80 mg/m2 in 10 mg/m2 increments. Paclitaxel was administered at 110 and then 135 mg/m2. The combination regimen was given as first-line chemotherapy of MBC. Three to six patients per cohort were treated. RESULTS: Twenty-two patients were treated in the first four cohorts (oral VRL/PTX): 60/110, 70/110, 80/110 and 80/135. In cohort 4, seven patients were treated, one patient being non-evaluable for MTD, three of them presented a dose-limiting toxicity (DLT) consisting of febrile neutropenia and neutropenic infection. Therefore 80/135 was the MTD. Because 36% of oral VRL administrations on day 8 were delayed to day 15 at 80/110, two additional cohorts were tested: in cohort 5, oral VRL 60 mg/m2 on days 1 and 15 and PTX 135 mg/m2 on day 1 and in cohort 6, oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1, every 3 weeks. In cohort 5, six out of eight patients had DLTs: omission of oral VRL on day 15 for five patients, grade 4 neutropenia>7 days for another one. Therefore the recommended dose (RD) for further clinical testing was oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1 of an every 3-week cycle. Two of the three evaluable patients treated at the RD had a partial response. The pharmacokinetics of VRL and PTX is being analysed and will be further presented in a separate publication. CONCLUSIONS: This phase I study has determined the doses of oral VRL and PTX to be used in combination for the benefit of the patient and of the chemotherapy unit in term of nurse's workload. The recommended regimen of oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1 given every 3 weeks will be further tested in phase II.

RESUMEN

BACKGROUND: To determine the feasibility of two chemotherapy regimens in elderly patients with advanced ovarian carcinoma (AOC). PATIENTS AND METHODS: Eighty-three patients >or=70 years were previously enrolled in a trial evaluating carboplatin and cyclophosphamide (CC). On the basis of identical eligibility criteria, 75 further patients were enrolled in a trial evaluating carboplatin and paclitaxel (Taxol) (CP). The primary end point of these studies was the feasibility of six courses of chemotherapy. Comprehensive geriatric assessment (CGA) parameters were assessed in terms of prognostic factors. RESULTS: More patients in the CC group presented with performance status of two or more, depression symptoms, use of co-medications, hypoalbuminemia, abnormal Mini-Mental Status score, or sub-optimal surgery. Both regimens appeared feasible: 75.6% in the CC group and 68.1% in the CP group completed six courses. CC and CP groups had similar overall survival (OS). Independent prognostic factors of poorer OS were the following: increasing age (P = 0.013), depression symptoms at baseline (P < 0.001), International Federation of Gynecology and Obstetrics stage IV (P = 0.001), and use of paclitaxel (P = 0.025). CONCLUSION: As this is a non-randomised retrospective review of two consecutive studies, no firm conclusion can be drawn. It seems, however, that in elderly patients with AOC the use of paclitaxel results in more toxicity. CGA parameters and particularly emotional disorders might help to determine a priori the risk/benefit ratio of chemotherapy in this patient population.
