Cancer-related fatigue management: evaluation of a patient education program with a large-scale randomised controlled trial, the PEPs fatigue study.

BACKGROUND: To assess the efficacy of a patient educational program built according to guidelines that aims at reducing cancer-related fatigue (CRF). METHODS: Randomised controlled trial, multicentre, comparing a patient education program, vs the standard of care. Patients were adult cancer outpatients with any tumour site. The primary outcome was fatigue severity assessed with a visual analogical scale (VAS), between the day of randomisation and week 7. Secondary outcomes were fatigue assessed with other scales, health-related quality of life, anxiety and depression. The time to fatigue severity deterioration was assessed. Analyses were performed in a modified intent-to-treat way, that is, including all patients with at least one baseline and 1 week 7 score. RESULTS: A total of 212 patients were included. Fatigue severity assessment was made on 79 patients in the experimental group and 65 in the control group. Between randomisation and week 7, the fatigue (VAS) improved by 0.96 (2.85) points in the experimental group vs 1.63 (2.63) points in the control group (P=0.15). No differences with the secondary outcomes were highlighted between two groups. No other factors were found to be associated with fatigue severity deterioration. CONCLUSIONS: Despite rigorous methodology, this study failed to highlight the program efficacy in fatigue reduction for cancer patients. Other assessment tools should be developed to measure the effect of the program on CRF and behaviour. The implementation of the program should also be explored in order to identify its mechanisms and longer-term impact.

EPICC study: evaluation of pharmaceutical intervention in cancer care.

WHAT IS KNOWN AND OBJECTIVES: In cancer care, clinical pharmacists contribute to improving prevention and management of drug-related problems (DRPs). The 3-year EPICC study (Evaluation of Pharmaceutical Intervention in Cancer Care) aimed to collect and analyse pharmaceutical interventions (PIs) in oncology. METHODS: The free online version of the French Society of Clinical Pharmacy (SFPC) coding system, ACT-IP, was used, supplemented by a standardized dedicated cancer-care decision tree. RESULTS: A total of 29,589 medication orders (77,004 anticancer drug preparations) were analysed. Eight hundred and ninety-four PIs were recorded. ACT-IP identified 54·1% of DRPs as concerning over- or underdosage. The standardized dedicated cancer-care decision tree identified the three principal causes of dosage problems: 50·2% due to miscalculation, 20% to omission of dose adjustment and 12% to poor choice of antineoplastic regimen. About 13·8% of DRPs were adverse effects and 3·9% were drug-drug interactions. The decision tree showed that 22% of adverse events could be circumvented by a switch within the same drug family and 72% of drug-drug interactions would have led to increased neoplastic toxicity. DISCUSSION: Pharmaceutical analysis of prescription forms contributes to medication safety in cancer care, and the present dedicated decision tree highlights additional information about DRPs and PIs. The DRP rate (3% of prescriptions) was consistent with the literature. The pharmacist has a role to play in optimizing the management of patients with cancer in terms of dose adjustment, drug toxicity management, improvement of administration and drug-drug interactions. WHAT IS NEW AND CONCLUSION: This study, highlighting PIs in cancer care, is the first of this scale in terms of number of prescriptions analysed (nearly 30 000). Results demonstrated the specificity of DRPs and PIs for patients with cancer and the value of a dedicated coding system in cancer care.

SIMMEON-Prep study: SIMulation of Medication Errors in ONcology: prevention of antineoplastic preparation errors.

WHAT IS KNOWN AND OBJECTIVE: Medication errors (ME) in oncology are known to cause serious iatrogenic complications. However, MEs still occur at each step in the anticancer chemotherapy process, particularly when injections are prepared in the hospital pharmacy. This study assessed whether a ME simulation program would help prevent ME-associated iatrogenic complications. METHODS: The 5-month prospective study, consisting of three phases, was undertaken in the centralized pharmaceutical unit of a university hospital of Lyon, France. During the first simulation phase, 25 instruction sheets each containing one simulated error were inserted among various instruction sheets issued to blinded technicians. The second phase consisted of activity aimed at raising pharmacy technicians' awareness of risk of medication errors associated with antineoplastic drugs. The third phase consisted of re-enacting the error simulation process 3 months after the awareness campaign. The rate and severity of undetected medication errors were measured during the two simulation (first and third) phases. The potential seriousness of the ME was assessed using the NCC MERP(®) index. RESULTS AND DISCUSSION: The rate of undetected medication errors decreased from 12 in the first simulation phase (48%) to five in the second simulation phase (20%, P = 0.04). The number of potential deaths due to administration of a faulty preparation decreased from three to zero. Awareness of iatrogenic risk through error simulation allowed pharmacy technicians to improve their ability to identify errors. WHAT IS NEW AND CONCLUSION: This study is the first demonstration of the successful application of a simulation-based learning tool for reducing errors in the preparation of injectable anticancer drugs. Such a program should form part of the continuous quality improvement of risk management strategies for cancer patients.

Phase I dose-escalation study of aflibercept in combination with docetaxel and cisplatin in patients with advanced solid tumours.

BACKGROUND: This phase I cohort study investigated aflibercept (vascular endothelial growth factor (VEGF) trap) plus docetaxel and cisplatin in patients with advanced solid tumours. METHODS: Patients received intravenous aflibercept 4, 5, or 6 mg kg(-1) with docetaxel and cisplatin (75 mg m(-2) each) on day 1 of a 3-week cycle until progressive disease or unacceptable toxicity. Primary objectives were determining cycle 1 dose-limiting toxicities (DLTs) and the aflibercept recommended phase II trial dose (RP2D) for this combination. RESULTS: During the dose-escalation phase (n=16), there were two DLTs of febrile neutropenia (at 4 and 5 mg kg(-1)). Granulocyte colony-stimulating factor prophylaxis was subsequently recommended. The RP2D of aflibercept was established at 6 mg kg(-1) and administered to 14 additional patients. The most frequent grade 3/4 adverse events (AEs) were neutropenia (43.3%), stomatitis (20.0%), asthenia/fatigue (20.0%), and hypertension (16.7%). All-grade AEs associated with VEGF blockade included epistaxis (83.3%), dysphonia (70.0%), proteinuria (53.3%), and hypertension (50.0%). There were five partial responses (16.7%) and 18 cases of stable disease (60.0%) (lasting >3 months in 10 patients). There were no pharmacokinetic (PK) interactions between the three drugs. CONCLUSION: Aflibercept 6 mg kg(-1) with docetaxel and cisplatin 75 mg m(-2) every 3 weeks is the RP2D based on tolerability, antitumour activity, and PKs.

Long-term follow-up of HER2-overexpressing stage II or III breast cancer treated by anthracycline-free neoadjuvant chemotherapy.

BACKGROUND: Very effective trastuzumab-based primary systemic therapy (PST) can be proposed for conservative surgery purpose to human epidermal growth factor receptor 2 (HER2)-positive breast cancer (HER2+BC). Long-term follow-up (LTFU) warrants further data. PATIENTS AND METHODS: LTFU of patients, with stage II/III HER2+BC, treated by trastuzumab associated with docetaxel (Taxotere(®)) and/or carboplatin used as anthracycline-free PST was studied. RESULTS: Among 135 patients, with a median follow-up of 48.3 months [95% confidence interval (CI) 45.3-52.4 months], the relapse-free survival (RFS) rate was 73.2% (95% CI 63.76% to 80.55%) while the overall survival (OS) rate was 91.87% (95% CI 84.23% to 95.90%). Adjuvant trastuzumab favorably influenced RFS in univariate analysis while the pathological nodal invasion unfavorably influenced RFS [Cox multivariate analysis (hazard ratio = 2.80, 95% CI 1.36-5.76, P = 0.0052)] and OS. Cardiac toxicity was minor (2.2% transient, reversible asymptomatic decrease in left ventricular ejection fraction). CONCLUSION: This is the first report of LTFU showing that anthracycline-free trastuzumab-based PST combined either with docetaxel and/or carboplatin can achieve, without cardiac toxicity, very competitive results in terms of pathological complete response, RFS and OS, in HER2+BC. The choice of this schedule could be proposed to patients with vascular contraindication for anthracyclines or because patient's or physician's preference for a taxane-only schedule.

Chemotherapy may be delivered based on an integrated view of tumour dynamics.

The aim here was to explore the potential of pharmacokinetic (PK)/pharmacodynamic (PD) and physiopathological parameters in explaining the primary effects of an anti-cancer treatment that targets cells in a specific cell cycle phase. The authors applied a theoretical multi-scale disease model of tumour growth that integrates cancer processes at the cellular and tissue scales. The mathematical model at the cell level relies on a dynamic description of cell cycle regulation while the model at the tissue level is based on fluid mechanics considerations. Simulations show that the number of target cells oscillates as the tumour grows after a first cycle of chemotherapy. Both treatment effect and tumour growth processes drive these oscillations. Nonetheless, results indicate that parameters related to physiopathological processes may have greater relevance than classical drug-related parameters in determining the efficacy of a chemotherapy treatment protocol. Physiopathological parameters, in particular those related to cell cycle regulation, may be integrated in PK/PD models aimed at optimising the delivery of phase-specific cytotoxic treatments.

[Evaluation of treatment relating to gestational trophoblastic tumor registered to the French Trophoblastic Disease Reference Center (TDRC) in Lyon from 1999 to 2005]. / Evaluation de la prise en charge des tumeurs trophoblastiques gestationnelles enregistrées au Centre de référence des maladies trophoblastiques de Lyon de 1999 à 2005.

OBJECTIVES: The aim of this study was both to analyse if gestational trophoblastic neoplasia (GTN) registered to the French Trophoblastic Disease Reference Center (TDRC) in Lyon (France) were managed according to the FIGO criteria for diagnosis of GTN and if chemotherapy was adapted to the 2000 FIGO prognostic scoring system. PATIENTS AND METHODS: Retrospective, descriptive analysis of 167 GTN registered to GTC of Lyon between 1999 and 2005. RESULTS: On the one hand, 66% of women (104/158) had a diagnosis of GTN according to FIGO criteria. One third (n=54) of the patients therefore had a premature or erroneous diagnosis of a tumor, when the treatment started. No supporting element of this premature diagnosis has been found out for 26 patients. The identification of lung and vaginal metastasis and histological diagnosis of invasive mole appeared as the most mentioned inappropriate criteria for diagnosis. On the other hand, chemotherapy was adapted to 2000 FIGO scoring in 91, 5% of cases. Twelve low risk GTN were treated with polychemotherapy and two high risk GTN were treated with monochemotherapy. Moreover 29% of the patients received a non adequate treatment due to deviations from the recommended protocol. DISCUSSION AND CONCLUSION: Non respect of FIGO criteria for the diagnosis of GTN can lead to erroneous diagnosis of tumors. Identification of lung or vaginal metastasis or diagnosis of invasive mole should not automatically justify the diagnosis of gestational trophoblastic neoplasia if the decrease in HCG occurs properly. Respect of FIGO criteria for the diagnosis of GTN and adaptation of chemotherapy to 2000 FIGO scoring are necessary to avoid inadequate treatment of gestational trophoblastic neoplasia.

[Role of gynecologists in the care of women with breast cancer]. / La place des médecins gynécologues libéraux dans la prise en charge des femmes atteintes de cancer du sein.

OBJECTIVES: To describe the role of gynecologists in the care of women with breast cancer, their relationship with hospital specialists and with patients, and their expectations in terms of the quality of this relationship. MATERIALS AND METHODS: A descriptive cross-sectional study was performed in 2002. Two hundred and fifty gynecologists from Rhone Alpes region were randomly selected and received a questionnaire. RESULTS: Sixty-four percent of the polled practitioners answered. Forty-two percent of gynecologists had about 25-50 patients with breast cancer. Their participation in the care principally concerned the phases of diagnosis (99%) and remission (98.5%). Eight percent took part in therapeutic decision making. Ninety-two percent of the gynecologists wanted to receive systematically feedback concerning any consultation or hospitalization and 98% wanted to know the name and address details of the care coordinator. CONCLUSION: Gynecologists are willing to participate in the care of breast cancer patients. This for, they want to have more details about therapy, follow-up and the level of information given to the patients.

Any clinical benefit from the use of oncofoetal markers in the management of chemotherapy for patients with metastatic colorectal carcinomas?

AIMS: Computed tomography (CT) is the reference technique for evaluating response to chemotherapy. The potential helpfulness of tumour markers is debated. MATERIALS AND METHODS: From March 1997 to January 1999, 91 consecutive patients receiving chemotherapy for metastatic colorectal carcinoma underwent whole-body spiral CT, estimates of anti-carcinoembryonic antigen (CEA) and CA19-9 every 8 weeks. RESULTS: CEA and CA19-9 levels were above normal in 78 (85.7%) and 61 (67.5%) patients, respectively. Tumour response evaluation according to the RECIST criteria was obtained at 8-week evaluation in 83 (91%) patients. The positive predictive values (PPV) for response of a decrease of the marker levels were 53.8 for CEA and 41.7 for CA19-9 using a 30% decrease threshold, and 60/52.2, respectively, using a 50% decrease threshold. Meaningful PPV values (> 90%) for progression of an increase of the marker levels were only obtained using the 200% increase threshold for CEA alone or a combination of CEA and CA 19-9. A 100% CEA increase between baseline and the 8-week evaluation was correlated to overall survival (P = 0.0023). The need for a radiological confirmation of tumour progression could be avoided by the systematic dosage of tumour markers at baseline and after 8 weeks of treatment only in a sub-population of 13% of the patients with a 200% increase of CEA or CA 19-9 at 8 weeks. CONCLUSIONS: CEA, CA 19-9, or both should be used with caution for tumour response evaluation to chemotherapy in addition to CT in metastatic colorectal carcinoma.

Intraperitoneal chemohyperthermia using a closed abdominal procedure and cytoreductive surgery for the treatment of peritoneal carcinomatosis: morbidity and mortality analysis of 216 consecutive procedures.

BACKGROUND: Peritoneal carcinomatosis has been regarded as a lethal clinical entity. Recently, aggressive treatments combining intraperitoneal chemohyperthermia (IPCH) with cytoreductive surgery have resulted in long-term survival in selected patients. The aim of this trial was to analyze the mortality and morbidity of 216 consecutive treatments of peritoneal carcinomatosis by IPCH by using a closed abdominal procedure combined with cytoreductive surgery. METHODS: Between February 1989 and August 2001, 207 patients who underwent 216 IPCH procedures using a closed abdominal procedure with mitomycin C, cisplatin, or both were prospectively studied. RESULTS: The postoperative mortality and morbidity rates were 3.2% and 24.5%, respectively. The most frequent complications were digestive fistula (6.5%) and hematological toxicity (4.6%). Morbidity was statistically linked with the carcinomatosis stage (P =.016), the duration of surgery (P =.005), and the number of resections and peritonectomy procedures (P =.042). Duration of surgery and carcinomatosis stage were the most common predictors of morbidity. CONCLUSIONS: The frequency of complications after IPCH and cytoreductive surgery was mainly associated with the carcinomatosis stage and the extent of the surgical procedure. The IPCH closed abdominal procedure has shown an acceptable frequency of adverse events.

Phase II study of oral vinorelbine in first-line advanced breast cancer chemotherapy.

PURPOSE: A phase II trial was performed to evaluate the efficacy, tolerance, and pharmacokinetic profiles of oral vinorelbine (Navelbine). Oral Navelbine (NVB; Pierre Fabre Médicament, Boulogne, France) was given as first-line chemotherapy for locally advanced or metastatic breast carcinoma (ABC). PATIENTS AND METHODS: Sixty-four patients were entered to receive oral NVB on a weekly basis for a total of 8 weeks unless progression or toxicity occurred. Oral NVB was given at 60 mg/m(2) weekly for the first three administrations and was increased to 80 mg/m(2) for the subsequent administrations if there was no grade 4 neutropenia or no more than one episode of grade 3 neutropenia. Patients with objective response or stable disease continued treatment up to a total of 12 weeks or more. RESULTS: Fifty-eight evaluable patients were included in our study. Four patients (6.9%) had complete responses, and 14 (24.1%) had partial responses, for an overall response rate of 31% (95% CI, 19% to 43%). Median progression-free survival was 17.4 weeks. Median overall survival is not yet reached. There were no treatment-related deaths. The main toxicity was neutropenia: grade 4 in 17.2% of the patients, and 1.8% of administrations and associated clinical serious events in 4 patients (6.2%). Grade 3 and 4 nausea and/or vomiting were noted in 3.1% and 4.6% of the patients, respectively. Only one patient developed grade 3 neuroconstipation. An analysis of Quality of Life Questionnaire C30 forms revealed no significant alteration between baseline and weeks 8 and 16 in global quality of life. CONCLUSION: Oral NVB at this schedule is an effective and well-tolerated agent in the treatment of ABC and offers a promising alternative to the intravenous route. Combination studies are ongoing.

Assessment of tumour response to chemotherapy for metastatic colorectal cancer: accuracy of the RECIST criteria.

Evaluation of tumour size modifications in response to treatment is a critical issue in the management of advanced malignancies. In 1981, the World Health Organization (WHO) established guidelines for tumour response assessment. These WHO1981 criteria were recently simplified in a revised version, named RECIST (Response Evaluation Criteria in Solid Tumours), which uses unidimensional instead of bidimensional measurements, a reduced number of measured lesions, withdrawal of the progression criteria based on isolated increase of a single lesion, and different shrinkage threshold for definitions of tumour response and progression. In order to validate these new guidelines, we have compared results obtained with both classifications in a prospective series of 91 patients receiving chemotherapy for metastatic colorectal cancer. Data from iterative tomographic measurements were fully recorded and reviewed by an expert panel. The overall response and progression rates according to the WHO1981 criteria were 19% and 58%, respectively. Using RECIST criteria, 16 patients were reclassified in a more favourable subgroup, the overall response rate being 28% and the progression rate 45% (non-weighted kappa concordance test 0.72). When isolated increase of a single measurable lesion is not taken into account for progression with the WHO1981 criteria, only 7 patients were reclassified and the kappa test was satisfying, i.e. > or =0.75, for the whole population as well as for each of the responding and progressive subgroups. Since it provides concordant results with a simplified method, the use of RECIST criteria is recommended for evaluation of treatment efficacy in clinical trials and routine practice.

[General principles of dose-effect relationship]. / Les principes généraux de l'effet-dose.

The principles of chemotherapy administration are based on its haematological toxicity. In 1979, Goldie and Coldman described a mathematical model to demonstrate the link between the dose schedule and the cytotoxicity. Some years later, Norton and Simon developed this concept by integrating a tumour growth model taking into account the parameters of the in vivo tumoral homeostasis. The limits of the results obtained in the treatment of many cancers and the recent development of haematopoietic supports has led the clinicians to reconsider the therapeutic modalities and to intensify the treatments. We recall herein the principles of therapeutic intensification. In introduction of the various clinical applications, this chapter briefly calls back the theoretical bases of the concepts of dose response, dose-density and dose-intensity.

[Dose intensity of chemotherapy in small-cell lung carcinoma]. / Intensification thérapeutique des carcinomes bronchopulmonaires à petites cellules.

Small cell lung cancer accounts for 20% of the primitive lung carcinomas. The pronostic is unfavourable, since two thirds of the patients present with extensive stage at diagnosis. The median survival without treatment is less than 3 months. Chemotherapy is the standard front line therapy. In selected patients, chest irradiation and so-called prophylactic cerebral irradiation are current options. Small cell lung cancer is a chemosensitive disease. Indeed, the response rate is around 80-95% of in limited disease patients of which 50-60% are complete responses. Despite these results, the median survival does not exceed 16 months. Early recurrences after initial response probably reflect various resistances mechanisms. Furthermore, small cell lung cancer is associated with a high fraction of dividing cells. It is a clinical model where the dose-response relationship concept is worth testing, and dose-intensity may be integrated into the therapeutic strategies. Therefore, many clinical trials have assessed these principles during the past 20 years. We present here the different methods of therapeutic intensification in small cell lung cancer: with or without hematopoïetic supports, using initial high dose of cytotoxic drugs, either at the beginning or at the end of induction treatment, or by increasing the dose-density.

Addition of oxaliplatin to continuous fluorouracil, l-folinic acid, and concomitant radiotherapy in rectal cancer: the Lyon R 97-03 phase I trial.

PURPOSE: Oxaliplatin could increase the efficacy of fluorouracil (5-FU)/folinic acid chemoradiotherapy in rectal cancer. We tested three dose levels to identify a feasible oxaliplatin dose for combination therapy. PATIENTS AND METHODS: Between February 1998 and April 2000, we included 17 rectal adenocarcinoma patients in a single-center phase I study. Patients had T4 rectal carcinoma, T1-T3 disease with colostomy refusal, or potentially operable T2/T3 M1 requiring local treatment. Pelvic radiotherapy was 45 Gy over 5 weeks, 1.8 Gy/fraction, with concomitant chemotherapy weeks 1 and 5. Chemotherapy was oxaliplatin 80, 100, or 130 mg/m2 2-hour infusion on day 1 followed by L-folinic acid 100 mg/m2/d intravenous bolus, and 5-FU 350 mg/m2/d continuous infusion on days 1 to 5 (FolfoR1). Six patients refusing surgery received additional contact radiotherapy +/- brachytherapy. Dose escalation proceeded if less than two of six patients had dose-limiting toxicity (DLT) at a given dose-level. RESULTS: All except two patients completed treatment; patients at level 1 (prolonged grade 1 thrombocytopenia) and level 3 (prolonged cold-related dysesthesia) had no second chemotherapy course. Median follow-up is 14 months (range, 2 to 28 months). One elderly patient at dose level 1 had DLT asthenia, severe diarrhea and vomiting, and more than 10% weight loss. There were no other DLTs and no severe rectitis or gastrointestinal toxicity. There were objective responses at all doses and no progressions. Eight patients underwent radical surgery after chemoradiotherapy. Two had complete pathologic responses. CONCLUSION: FolfoR1 seems feasible and effective. Dose escalation did not increase toxicity. Although the MTD was not reached in this study, we recommend oxaliplatin 130 mg/m2 for phase II studies because it is the dose determined from studies in metastatic patients with no toxicity when given concurrently with radiation.
