RESUMEN

HannaH (NCT00950300) and PrefHer (NCT01401166) studies validated the subcutaneous (H-s.c.) formulation of trastuzumab as effective and safe as intravenous (H-i.v.) and highly preferred by patients in early breast cancer. The present randomised MetaspHer trial (NCT01810393) is the first study assessing patient's preference in metastatic setting. METHODS: Patients with HER2-positive metastatic breast cancer who completed a first line chemotherapy with trastuzumab and achieved a long-term response lasting more than 3 years were randomised to receive 3 cycles of 600-mg fixed-dose adjuvant H-s.c., followed by 3 cycles of standard H-i.v., or the reverse sequence. Primary end-point was overall preference for H-s.c. or H-i.v. at cycle six, assessed by Patient Preference Questionnaire (PPQ). Secondary end-points included healthcare professional (HCP) satisfaction; safety and tolerability; quality of life. RESULTS: Hundred and thirteen patients were randomised and treated. H-s.c. was preferred by 79/92 evaluable intent-to-treat patients (85.9%, 95% confidence interval [CI; 78.8-93.0]; p < 0.001), 13/92 preferred H-i.v. (14.1%, 95% CI [7.0-21.3]). HCPs were most satisfied with H-s.c. (56/88 available data, 63.6%, [53.6-73.7]). On the safety population, adverse events occurred in 73 (67.6%) and 49 (44.1%) patients during the H-s.c. and H-i.v. periods, respectively; 7 (6.5%) and 4 (3.6%) were grade ≥ III, 3 (2.8%) and 2 (1.8%) were serious. CONCLUSION: The safety was consistent with the known H-i.v. and H-s.c. profiles without safety concern raised. Definitively, patients preferred H-s.c. as reported in early stage by PrefHer study.

RESUMEN

BACKGROUND: Platinum-based systemic chemotherapy is considered the backbone for management of advanced urothelial carcinomas. However there is a lack of real world data on the use of such chemotherapy regimens, on patient profiles and on management after treatment failure. METHODS: Fifty-one randomly selected physicians from 4 European countries registered 218 consecutive patients in progression or relapse following a first platinum-based chemotherapy. Patient characteristics, tumor history and treatment regimens, as well as the considerations of physicians on the management of urothelial carcinoma were recorded. RESULTS: A systemic platinum-based regimen had been administered as the initial chemotherapy in 216 patients: 15 in the neoadjuvant setting, 61 in adjuvant therapy conditions, 137 in first-line advanced setting and 3 in other conditions. Of these patients, 76 (35 %) were initially considered as cisplatin-unfit, mainly because of renal impairment (52 patients). After platinum failure, renal impairment was observed in 44 % of patients, ECOG Performance Status ≥ 2 in 17 %, hemoglobinemia < 10 g/dL in 16 %, hepatic metastases in 13 %. 80 % of these patients received further anticancer therapy. Immediately after failure of adjuvant/neoadjuvant chemotherapy, most subsequent anticancer treatments were chemotherapy doublets (35/58), whereas after therapy failure in the advanced setting most patients receiving further anticancer drugs were treated with a single agent (80/114). After first progression to chemotherapy, treatment decisions were mainly driven by Performance Status and prior response to chemotherapy (>30 % patients). The most frequent all-settings second anticancer therapy regimen was vinflunine (70 % of single-agent and 42 % of all subsequent treatments), the main reasons evoked by physicians (>1 out of 4) being survival benefit, safety and phase III evidence. CONCLUSION: In this daily practice experience, a majority of patients with urothelial carcinoma previously treated with a platinum-based therapy received a second chemotherapy regimen, most often a single agent after an initial chemotherapy in the advanced setting and preferably a cytotoxic combination after a neoadjuvant or adjuvant chemotherapy. Performance Status and prior response to chemotherapy were the main drivers of further treatment decisions.

RESUMEN

BACKGROUND: Everolimus is an agent frequently associated with specific toxicities. Predictive markers of efficacy are needed to help define which patients could benefit from it. The goal of this exploratory study was to identify potential predictive biomarkers in the mammalian target of rapamycin (mTOR) complex 1 (mTORC1) activation pathway using primary tumor samples collected during the phase II tamoxifen plus everolimus (TAMRAD) trial. PATIENTS AND METHODS: Tumor tissues were collected retrospectively from the TAMRAD trial. Immunohistochemistry was carried out using specific antibodies directed toward proteins that result in mTORC1 activation [canonical phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mTOR or alternative pathways]. DNA was extracted from the tumor tissue; mutation screening in the PIK3CA gene (exons 9 and 20) and the KRAS gene (exons 2 and 3) was first carried out using Sanger direct sequencing, and then completed by next-generation sequencing for PIK3CA. An exploratory analysis of everolimus efficacy in terms of a time-to-progression (TTP) increase was carried out in each biomarker subgroup (high versus low expression referring to the median percentage of marked cells). RESULTS: A total of 55 primary tumor samples from the TAMRAD trial­25 from the tamoxifen-alone group and 30 from the tamoxifen/everolimus group­were evaluated for biomarkers. The subgroups most likely to have an improvement in TTP with tamoxifen/everolimus therapy, compared with tamoxifen alone, were patients with high p4EBP1, low 4EBP1, low liver kinase B1, low pAkt, and low PI3K. Among the 45 samples screened for mutation status, nine samples (20%; 95% CI 9.6-34.6) had a PIK3CA mutation. KRAS mutation was observed in one patient. CONCLUSIONS: A positive correlation between late effectors of mTORC1 activation, a positive correlation between Akt-independent mTORC1 activation, and an inverse correlation between canonical PI3K/Akt/mTOR pathway and everolimus efficacy were observed in this exploratory analysis. However, these correlations need to be validated in larger studies before applying the findings to routine clinical practice.

RESUMEN

BACKGROUND: Sunitinib is an antiangiogenic tyrosine kinase inhibitor indicated in the treatment of metastatic renal cancer and gastrointestinal stromal tumours (GIST). We report a case of leg ulcer apparently triggered by this drug and we discuss the potential implication of the antiangiogenic effect of sunitinib in ulcer genesis. CASE REPORT: A 73-year-old woman with a history of deep venous thrombosis of the lower limbs was treated with sunitinib for renal cancer with hepatic and pulmonary secondaries. While on this treatment, she developed painful ulcers of the right lower limb, despite having never previously presented leg ulceration. On discontinuation of sunitinib, the lesions improved, and resumption of this drug, even at a lower dosage, resulted in relapse of her ulcers. DISCUSSION: Although questions may legitimately be asked about the contribution of the patient's venous condition, withdrawal of sunitinib followed by a positive rechallenge tend to suggest the role of this drug in recurrence of ulcers. Their recurrence despite the decreased dosage of the drug points to a nondose-dependent pathogenic mechanism.

RESUMEN

AIM: Evaluate efficacy and safety of epoetin beta in anaemic patients receiving chemotherapy for a non-myeloid malignancy. PATIENTS AND METHODS: This open-label, multicentric, clinical trial was conducted in France among 691 anaemic patients (haemoglobin < or = 12 g/dL) with a solid or haematological malignancy to evaluate the benefit of epoetin beta 30,000 IU/week subcutaneously for 16 weeks. The primary endpoint was the rate of therapeutic response. RESULTS: The overall response rate was 60.4% (CI 95%: [56.6%-64.1]). According to initial haemoglobin level < 11 g/dL or between 11 and 12 g/dL, it was 61.2% and 57.5% respectively. Response rates by tumour type (solid and haematological) were similar. The mean haemoglobin level increases were respectively 1.1 g/dL, approximately 2 and 2.2 g/dL at 4, 9, and 12 weeks after treatment initiation. In patients with haemoglobin level < 11 g/dL at inclusion the mean increases in haemoglobin level were respectively 1.17, 2.03 and 2.45 g/dL at 4, 9 and 12 weeks. During study period, 23% of patients required red blood cell transfusion. Overall treatment with epoetin beta was well-tolerated and 7.1% of patients only experienced thromboembolic events. CONCLUSION: For treating chemotherapy-induced anaemia in patients with solid or haematological malignancy (especially if haemoglobin level < 11 g/dL), epoetin beta 30.000 IU subcutaneously once-weekly (450 IU/kg/week) is rapidly effective and overall well-tolerated.

RESUMEN

Pegase 03 is a multicenter prospective randomized phase III trial evaluating the impact of first-line high-dose chemotherapy (HDC) with stem cell support on overall survival (OS), disease-free survival (DFS) and response rate in 308 patients with histologically proven metastatic breast cancer responding to induction therapy. Eligible patients received four induction cycles with FEC 100 (5-fluorouracil 500 mg/m(2), epirubicin 100 mg/m(2), cyclophosphamide 500 mg/m(2)). Patients with objective response (N=179) were randomized to one cycle of HDC (cyclophosphamide 6000 mg/m(2) and thiotepa 800 mg/m(2) (CHUT)) and stem cell support (N=88), or no further treatment (N=91). All patients were observed until disease progression or death. One toxic death occurred after CHUT. Other toxicities were manageable. The response rate at 3 months was higher in the intensification arm: 82.7% (25.3% complete response (CR)) versus 59.2% (14.1% CR) (P=0.0002). Median follow-up was 48 months. Median DFS was 11 and 6.6 months in the intensification and the observation arms, respectively (P=0.0001). There was no survival difference: 33.6 versus 27.3% OS at 3 years (P=0.8) and 22.9 versus 22.3 months median time to relapse in the intensification and observation arms, respectively. In this randomized trial, HDC with CHUT improved DFS but not OS, corroborating findings from earlier trials.

RESUMEN

Bacterial colonisation of wounds may delay wound healing. Modern silver-containing dressings are antimicrobial, yet cellular toxicity is a serious side-effect. We provide data for a newly formulated silver-containing ointment dressing, Atrauman Ag, for antimicrobial activity and cytotoxicity. Atrauman Ag effectively killed a panel of commensal skin as well as pathogenic bacterial strains while cytotoxicity for HaCaT keratinocytes was only around 10%. With these favourable in vitro tests, Atrauman Ag was analysed in 86 patients with traumatic and non-healing wounds of different aetiologies. The wound state was evaluated for 3 subsequent dressing changes. The slough score was reduced from 59.2 to 35.8%, granulation tissue increased from 27 to 40% and epithelialisation went up from 12.1 to 24%. We conclude that Atrauman Ag has a superior profile of antimicrobial activity over cellular toxicity and the low silver ion release rate may prevent interference with wound-healing mechanisms.

RESUMEN

BACKGROUND: The wet-wrap treatment has been reported to be beneficial in acute episodes of atopic dermatitis (AD) skin lesions. OBJECTIVE: The efficacy of topical corticosteroid prednicarbat with and without additional wet-wrap dressing was investigated in a prospective, randomized and controlled study. METHODS: In the left-right comparison study, 24 adults and children with an acute episode of AD were included. One arm or leg was randomly treated with the topical corticosteroid prednicarbat plus wet-wrap dressing; only prednicarbat was applied on the leg or arm of the other side. RESULTS: After 48-72 h of treatment, in both groups an improvement of the local SCORAD was observed. In comparison to the side of the body treated with corticosteroid alone, the decrease of the local SCORAD in the corticosteroid plus wet-wrap dressing group was significantly better. The severity of AD improved in the wet-wrap group at an average of 4.4 points, in the corticosteroid group 3.0 (p<0.011). CONCLUSIONS: Wet-wrap therapy with a topical corticosteroid is an effective treatment option in patients with exacerbated AD. The treatment is helpful in improving skin conditions, shortening the time of corticosteroid application.

RESUMEN

BACKGROUND: This multicenter, randomized, phase III study compared the efficacy, including progression-free survival (PFS), and safety of gemcitabine-docetaxel (GD) combination versus cisplatin-vinorelbine (CV) in the treatment of advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemonaive patients with stage IIIB or IV NSCLC were treated with GD (gemcitabine 1000 mg/m(2) days 1 and 8 plus docetaxel 85 mg/m(2) day 8, every 3 weeks for eight cycles) or CV (cisplatin 100 mg/m(2) day 1 plus vinorelbine 30 mg/m(2), days 1, 8, 15 and 22, every 4 weeks for six cycles). RESULTS: A total of 311 patients were enrolled (155 GD and 156 CV). Neither PFS nor overall survival differed significantly between the two arms (median PFS 4.2 and 4 months; median survival 11.1 and 9.6 months; 1-year survival 46% and 42%, for GD and CV, respectively). For the GD arm compared with the CV arm, the hazard ratio for PFS was 1.04 [95% confidence interval (CI) 0.83-1.32], and for overall survival, it was 0.90 (95% CI 0.70-1.16). Objective response rates did not differ significantly (31% for GD, 35.9% for CV). Myelosupression, emesis and frequency of febrile neutropenia were less pronounced on the GD arm, whereas fluid retention and pulmonary events were more pronounced. The CV arm experienced a higher number of serious adverse events and a lower compliance with the protocol. There was no quality of life (QoL) difference between arms. Median time to definite impairment of health-related QoL was 153 and 168 days in GD and CV arms, respectively. CONCLUSIONS: There was no advantage in PFS with GD compared with CV; however, the CV regimen had higher rate of toxic events, mainly myelosuppression. The herein, non-platinum-containing regimen could be considered as a rational alternative to the cisplatin-based doublet.

RESUMEN

BACKGROUND: This phase II trial compared docetaxel-cisplatin (DC) with vinorelbine-cisplatin (VC), both as first-line therapy followed by cross-over at progression to single-agent vinorelbine or docetaxel in advanced non-small-cell lung cancer (NSCLC). METHODS: Overall, 115 patients received DC (docetaxel 75 mg/m(2) and cisplatin 100 mg/m(2) both on day 1, every 3 weeks, arm A1) and 118 VC (vinorelbine 30 mg/m(2)/week on days 1 and 8 and cisplatin 100 mg/m(2) on day 1, every 3 weeks, arm B1) for six cycles, and subsequently maintained by monotherapy with docetaxel (A1) or vinorelbine (B1) with cross-over on disease progression to vinorelbine 30 mg/m(2) days 1 and 8 (A2), or docetaxel 100 mg/m(2), day 1, both every 3 weeks (B2). The primary end point was overall response rate (ORR). RESULTS: Patient characteristics were balanced; median follow-up was 8.8 months. First-line response rate was 33.9% with DC and 26.3% with VC (P=0.20). In arms A1 and B1, respectively: duration of response was similar (8.2 versus 8.4 months); median time to progression was 5 months in both; median survival was 8 versus 9 months (P=0.38); 1-, 2- and 3-year survival was 36% versus 35%, 17% versus 10% and 13% versus 6% (P not significant). However, with a low number of long-term survivors, statistical significance was not reached. Overall, almost half of the patients crossed over to second-line therapy; there were no response with vinorelbine and 6 (11.2%) partial responses with docetaxel. Considering the safety profile, the occurrence of febrile neutropenia was 9.6% with DC and 26.3% with VC. Treatment-related mortality was 2.5% with DC and 8.5% with VC. CONCLUSIONS: The trend in favour of the DC arm in ORR, even though statistical significance was not reached, is consistent with previous reports. This study suggests an activity of first-line DC in advanced NSCLC, and that second-line vinorelbine does not provide additional clinical benefit. As already shown in other studies, the use of DC in first-line should provide a better percentage of long-term survivors, despite the absence of efficacy of the second-line in our study.

RESUMEN

The activity of glufosfamide (beta-D-glucosylisophosphoramide mustard) was tested in a multicentre phase II clinical trial in patients with advanced non-small cell lung cancer (NSCLC) who had received one prior line of platinum-based chemotherapy. Patients were treated with 5000 mg/m(2) glufosfamide by a 1-h intravenous (i.v.) infusion every 3 weeks following registration at the European Organisation for Research and Treatment of Cancer (EORTC) Data Center. Patients were randomised between hydration and no hydration to evaluate the nephroprotective effects of forced diuresis. Patients experiencing >/= 35 micromol/l increase of serum creatinine compared with baseline values were taken off the treatment. The Response evaluation criteria in solid tumours (RECIST) criteria were applied for the response assessment. Blood sampling was performed for a pharmacokinetic analysis. 39 patients from seven institutions were registered and a median of three cycles was given (range 0-6) cycles; 20 patients were randomised to the hydration arm. Haematological toxicity was mild, but treatment-related metabolic and electrolytic abnormalities and increases of serum creatinine occurred in several patients. Hydration did not have any significant influence on the plasma pharmacokinetics of glufosfamide and did not show any nephroprotective effect. Only one confirmed partial remission was observed (response rate 3%; 95% (Confidence Interval (CI) 0-14) and 18 cases with stable disease (49%) were recorded as assessed by an independent panel. Median survival of all patients treated was 5.8 months (95% CI 4.2-7.9). In conclusion, glufosfamide administered by a 1-h infusion every 3 weeks has modest activity in advanced NSCLC patients after one prior platinum-based chemotherapy.

RESUMEN

The purpose of the study was to develop an optimized joystick control interface for electric powered wheelchairs and thus provide safe and effective control of electric powered wheelchairs to people with severe physical disabilities. The interface enables clinicians to tune joystick parameters for each individual subject through selecting templates, dead zones, and bias axes. In terms of hand tremor usually associated with people with traumatic brain injury, cerebral palsy, and multiple sclerosis, fuzzy logic rules were applied to suppress erratic hand movements and extract the intended motion from the joystick. Simulation results were presented to show the graphical tuning interface as well as the performance of the fuzzy logic controller.

RESUMEN

INTRODUCTION: High dose rate brachytherapy (HDR-BT) is an option for treatment of small invasive endobronchial carcinoma and carcinoma in situ. This retrospective study describes the results of 33 consecutive patients treated with curative intent and followed up for more than one year. METHODS: Between July 1994 and October 1999, 35 tumours were treated with HDR-BT alone using a standard protocol delivering 6 fractions of 5 Gy delivered across 1cm from the catheters over 3 to 6 weeks. In 31 patients, surgical treatment was ruled out because of histology (in situ carcinoma), history of pneumonectomy or significant co-morbidity. Two patients were treated for positive resection margins following pneumonectomy. All the tumours were Tis or T1 N0. RESULTS: The locations of tumours were: trachea - 2, main bronchus - 5, lobar - 20, and segmental - 8. Only one catheter was needed in 15 cases, 2 in 13 cases, 3 in 6 cases and 4 in 1 case. The median follow-up was 17 months (range, 5-53 months). The recurrence-free rate was 94.3% at 2 months and 86.2% at 6 months after the treatment. 15 patients (45.5%) developed local recurrence at a median time of 9 months. Three patients developed metastases. The 1-year and 2-year overall survival rate were 71.4% and 53.8% respectively and specific survival rates were 69.4% and 59%. One patient developed an acute pneumothorax, and late complications included 6 infections and 12 bronchial stenoses. There were no episodes of haemoptysis nor lethal complications. CONCLUSIONS: With strict selection criteria, HDR-BT can be a curative treatment for early invasive or in situ endobronchial carcinoma without serious toxicity. It is therefore a good alternative treatment with curative intent for inoperable patients.

RESUMEN

CONTEXT: The 'Standards, Options and Recommendations' (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French cancer centres and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone. METHODS: Data were identified by searching Medline and personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers, and to the medical committees of the 20 French cancer centres. RESULTS: The main recommendations for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone are: 1) The curative external irradiation with a continual course is an alternative to surgery only in the case of medically inoperable tumors or because the patient refuses surgery; 2) The external irradiation of the primary tumor only without the mediastinum could be proposed in peripheral stage IA. In proximal stage IA and IB, external irradiation should be carried out only as part of prospective randomised controlled trials comparing a localised irradiation of the primary tumor with a large irradiation of the mediastinum and the primary tumor. The treated volume must include the macroscopic tumoral volume with or without the microscopic tumoral volume and with a security margin from 1.5 to 2 cm; 3) There is a benefit to delivering a total dose in the primary tumor higher than 60 Gy in so far as the proposed irradiation, taking into account the respiratory function, does not increase the likelihood of severe adverse events due to radiation; and 4) The change in fractionation, the radiochemotherapy combination, the endobronchial brachytherapy with high dose rate alone or with external irradiation could be proposed only as part of prospective controlled trials for tumors classified as stage IB or II.

RESUMEN

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of locally advanced non small cell lung carcinoma. METHODS: Data were identified by searching Medline and the personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers and to the medical committees of the 20 French Cancer Centres. RESULTS: The main recommendations are: 1) The management of the locally advanced non small cell lung carcinoma has two main goals: firstly to obtain local control of the disease (or to at least delay local progression in order to improve the survival or relapse free survival), and secondly to prevent the development of metastases. 2) There is a consensus that locally advanced non small cell lung carcinoma should be irradiated. External beam radiotherapy should be of optimal quality and delivered at a minimal dose of 60 Gy by standard fractionation. For patients with a poor life expectancy, this can be delivered as a split-course or hypofractionated scheme. 3) Treatment for patients with a performance status of 0-1 should consist of short duration induction chemotherapy (with a least two drugs one of which must be cisplatin), combined sequentially with conventional radiotherapy. 4) Surgery is contraindicated in extensive N3 disease. Combined radio-chemotherapy (adjuvant or neoadjuvant) is not indicated outside clinical trials. Surgery is justified in stage N2 disease as good local control can be achieved. T4-N0 disease should be treated surgically with curative intent.

RESUMEN

Andrew Taylor Still, MD, DO, included in his founding postulates of osteopathy the concept that a patient's health includes the health of a patient's spirit. In the recent past, medicine as a whole, and osteopathic medicine specifically, has neglected this postulate. Recent research has confirmed the validity of Still's postulate, and many medical training institutions have received grants and established programs to incorporate spirituality into their curriculum. As with any patient evaluation, the history and physical examination is the starting platform. This article describes several tools that can be easily incorporated into the history and physical examination, along with some of the obstacles in evaluating the health of the patient's spirit.

RESUMEN

PURPOSE: New endobronchial techniques of treatment allow a good unblocking. Nevertheless, only high dose rate brachytherapy delivers a curative treatment for invasive carcinomas. This study analyses the results of the first 33 consecutive patients treated with curative intent by this technique from 1994 to 1997, and followed-up more than one year. PATIENTS AND METHODS: Thirty-seven lesions were treated, with usual schedule delivering 30 Gy at 1 cm depth in six fractions and three to five weeks. All the patients were meticulously selected on the local involvement of the tumour and absolute contraindications to a surgical treatment. All of them have a pulmonary disease history or a general contraindication. RESULTS: With a 14-month follow-up, the local control at two months after the treatment was 95% (endoscopic and histologic), and 90% of the patients presented a prolonged local control. Four patients died of the treated cancer, another of a controlateral cancer. Ten patients died of another disease, five of them from a respiratory insufficiency. The overall survival rate at two years was 53% and the specific survival rate 80%. The acute tolerance was good, without incident. Asymptomatic bronchial stenoses, described by endoscopic follow-up, were described for seven patients. CONCLUSION: We conclude that, on the basis of a good selection of the patients and a respect of the indications, high dose rate endobronchial brachytherapy is an effective curative treatment. It offers a new curative option and must be proposed for the small invasive carcinomas in non-operable patients.
