The effects of an integrated supportive care intervention on quality of life outcomes in outpatients with breast and gynecologic cancer undergoing chemotherapy: Results from a randomized controlled trial.

The aim of the Complementary Nursing in Gynecologic Oncology study was to investigate the effects of a complex, nurse-led, supportive care intervention using Complementary and Integrative Medicine (CIM) on patients' quality of life (QoL) and associated patient-reported outcomes. In this prospective, pragmatic, bicentric, randomized controlled trial, women with breast or gynecologic cancer undergoing a new regimen of chemotherapy (CHT) were randomly assigned to routine supportive care plus intervention (intervention group, IG) or routine care alone (control group, CG). The intervention consisted of CIM applications and counseling for symptom management, as well as CIM information material. The primary endpoint was global QoL measured with the EORTC-QLQ-C30 before and after CHT. Mixed linear models considering fixed and random factors were used to analyze the data. In total, 126 patients were randomly assigned into the IG and 125 patients into the CG (median age 51 years). The patients' medical and socio-demographic characteristics were homogenous at baseline and at follow-up. No group effects on QoL were found upon completion of CHT (estimate -1.04 [-4.89; 2.81]; P = 0.596), but there was a significant group difference in favor of the IG 6 months later (estimate 6.643 [1.65; 11.64]; P = 0.010). IG patients did also experience significant better emotional functioning (P = 0.007) and less fatigue (P = 0.027). The tested supportive intervention did not improve patients' QoL outcomes directly after CHT (T3), but was associated with significant QoL improvements when considering the change from baseline to the time point T4, which could be assessed 6 months after patients' completion of CHT. This delayed effect may have resulted due to a strengthening of patients' self-management competencies.

Long-term add-on therapy (compassionate use) with oral artesunate in patients with metastatic breast cancer after participating in a phase I study (ARTIC M33/2).

BACKGROUND: The antimalarial artesunate (ART), a semisynthetic derivative of artemisinin from the Chinese herb artemisia annua has remarkable anticancer properties in vitro and in vivo. Its excellent safety profile known from short-term therapy in malaria was confirmed in an open phase I trial (ARTIC M33/2) for dose-finding as add-on therapy for four weeks. PURPOSE: Patients with metastatic breast cancer, who had not experienced any clinically relevant adverse events (AE) during participation in ARTIC M33/2, were offered to continue ART as compassionate use (CU). Regular monitoring was continued in order to ensure adequate individual safety and tolerability and to collect information about long-term treatment with ART. Clinically relevant AEs or second progression of disease during ART were reasons for discontinuation of the add-on therapy. STUDY DESIGN: Compassionate use was offered open-label to participants of ARTIC M33/2. METHODS: Patients continued to take 100, 150 or 200 mg oral ART daily as add-on therapy to their guideline-based oncological therapy. Clinical and laboratory monitoring included audiological and neurological examination, ECG, NTproBNP and reticulocyte determination. Cumulative treatment days and cumulative ART doses encompass both the phase I study as well as the continued add-on treatment period (CU). RESULTS: Following the 4 ±â€¯1 weeks of the phase I trial, thirteen patients continued the add-on therapy as CU, resulting in a total of 3825 treatment days. In individual patients up to 1115 cumulative treatment days (37 months) and cumulative ART doses up to 167.3 g were reached. A total of 25 AEs grade ≥ 2 at least possibly related to ART long-term add-on therapy were documented, two, six and 17 in dose groups 100, 150 and 200 mg/d ART respectively. Six of these AEs were classified as grade 3, two in patients taking 150 and four in patients on 200 mg/d, none of them being probably or certainly related to ART. CONCLUSIONS: In thirteen patients with metastatic breast cancer up to 200 mg/d long-term oral ART (2.3-4.1 mg/kg BW/d) in up to 1115 cumulative treatment days (37 months) did not result in any major safety concerns.

Semi-Individualized Homeopathy Add-On Versus Usual Care Only for Premenstrual Disorders: A Randomized, Controlled Feasibility Study.

OBJECTIVES: Premenstrual syndrome and premenstrual dysphoric disorder (PMS/PMDD) bother a substantial number of women. Homeopathy seems a promising treatment, but it needs investigation using reliable study designs. The feasibility of organizing an international randomized pragmatic trial on a homeopathic add-on treatment (usual care [UC] + HT) compared with UC alone was evaluated. DESIGN: A multicenter, randomized, controlled pragmatic trial with parallel groups. SETTINGS/LOCATION: The study was organized in general and private homeopathic practices in the Netherlands and Sweden and in an outpatient university clinic in Germany. SUBJECTS: Women diagnosed as having PMS/PMDD, based on prospective daily rating by the daily record of severity of problems (DRSP) during a period of 2 months, were included and randomized. INTERVENTIONS: Women were to receive UC + HT or UC for 4 months. Homeopathic medicine selection was according to a previously tested prognostic questionnaire and electronic algorithm. Usual care was as provided by the women's general practitioner according to their preferences. OUTCOME MEASURES: Before and after treatment, the women completed diaries (DRSP), the measure yourself concerns and well-being, and other questionnaires. Intention-to-treat (ITT) and per protocol (PP) analyses were performed. RESULTS: In Germany, the study could not proceed because of legal limitations. In Sweden, recruitment proved extremely difficult. In the Netherlands and Sweden, 60 women were randomized (UC + HT: 28; UC: 32), data of 47/46 women were analyzed (ITT/PP). After 4 months, relative mean change of DRSP scores in the UC + HT group was significantly better than in the UC group (p = 0.03). CONCLUSIONS: With respect to recruitment and different legal status, it does not seem feasible to perform a larger, international, pragmatic randomized trial on (semi-)individualized homeopathy for PMS/PMDD. Since the added value of HT compared with UC was demonstrated by significant differences in symptom score changes, further studies are warranted.

How the Consolidated Framework for Implementation Research Can Strengthen Findings and Improve Translation of Research Into Practice: A Case Study.

PURPOSE/OBJECTIVES: To answer how the planned intervention was performed in routine care, which factors supported or distracted from its implementation, and how key organizational structures have been built and sustained.
. RESEARCH APPROACH: Mixed-methods process evaluation.
. SETTING: Two German outpatient cancer clinics.
. PARTICIPANTS: Purposive sampling of 297 recruited patients with gynecologic cancer, their treating oncology nurses, and their interprofessional healthcare team, and the clinical stakeholders of two different outpatient cancer clinics.
. METHODOLOGIC APPROACH: Guided by the Consolidated Framework for Implementation Research (CFIR), five distinct interrelated substudies were designed to evaluate intervention characteristics, inner and outer settings, characteristics of the individuals involved, and the process of implementation. Quantitative and qualitative data will be analyzed separately and then integrated into a framework analysis.
. FINDINGS: Oncology nurses found the regular process analytic sessions to be beneficial, not only for sharing their experience, but also for experiencing social support and social connectedness.
. INTERPRETATION: Key implementation facets of the nurse-led intervention will be examined systematically. The results can guide future implementation processes, which need to be tailored to interested facilities.
. IMPLICATIONS FOR NURSING: The CFIR framework is well established but not yet widely applied in supportive treatment research. The current study aims to apply and combine this framework with the concept of intervention fidelity.

Prospective open uncontrolled phase I study to define a well-tolerated dose of oral artesunate as add-on therapy in patients with metastatic breast cancer (ARTIC M33/2).

PURPOSE: The antimalarial drug artesunate (ART) is a promising candidate for cancer treatment as it displays anticancer effects in various models. While in short-term treatment of malaria, an excellent safety profile has been found for ART, the potential long-term treatment of cancer patients demands a phase I dose-finding clinical trial determining the daily ART dose which would be well tolerated as add-on therapy. METHODS: Patients with metastatic breast cancer were to receive either 100 or 150 or 200 mg oral ART daily as add-on to their guideline-based oncological therapy for a study period of four weeks with frequent clinical and laboratory monitoring until 4-8 weeks thereafter. According to the statistical design, recruitment was scheduled in groups of three patients in order not to miss a more than 33% frequency of dose-limiting adverse events (DL-AE) prior to dose escalation. RESULTS: Twenty-three patients were recruited, and all planned dose levels were applied. During the actual trial period of 4 ± 1 weeks, three patients experienced six DL-AEs altogether (leucopenia, neutropenia, asthenia, anemia) possibly related to ART (not exceeding 33% in any dose level). CONCLUSIONS: Up to 200 mg/d (2.2-3.9 mg/kg/d) oral ART were safe and well tolerated; therefore, 200 mg/d are recommended for phase II/III trials. Safety monitoring should include reticulocytes, NTproBNP, as well as audiological and neurological exploration.

Investigation of ototoxicity of artesunate as add-on therapy in patients with metastatic or locally advanced breast cancer: new audiological results from a prospective, open, uncontrolled, monocentric phase I study.

PURPOSE: Artesunate (ART) has been used for a long time in the treatment of Plasmodium falciparum malaria and has been considered safe. The present phase I study aimed to determine the daily dose of ART that is well tolerated as add-on therapy in patients with breast cancer for 4 weeks of therapy. Ototoxicity could be a potential safety concern in settings different from malaria. Therefore, comprehensive audiological assessment was essential. METHODS: The ARTIC M33/2 study was a prospective, open, uncontrolled, monocentric phase I dose-escalation study to evaluate the safety and tolerability of ART in patients with advanced breast cancer. Patients received either 100, 150 or 200 mg oral ART daily for a test phase of 4 weeks as add-on therapy to their ongoing oncological treatment. For the investigation of the safety of ART for hearing, an audiological assessment was performed with each patient before the intake of ART and after 4 weeks of therapy. RESULTS: Twenty-three female patients were included in the study. During the test phase, four patients had adverse events (AEs) of the auditory system possibly related to the intake of ART. However, none of these AEs was classified as severe AE (SAE) and did not require treatment interruption. Four patients had AEs concerning the vestibular system (vertigo) during the test phase, one of which was classified as SAE. However, the SAE was fully reversible after discontinuation of ART. CONCLUSION: None of the audiological results after 4 weeks of therapy with ART showed any dose-limiting auditory toxicity. However, audiological monitoring in further clinical studies with prolonged use of oral ART in doses up to 200 mg daily is warranted. The ARTIC M33/2 study is registered at eudract.ema.europa.eu with the Number 2007-004432-23 and at clinicaltrials.gov with the Number NCT00764036.

Developing and implementing a complex Complementary and Alternative (CAM) nursing intervention for breast and gynecologic cancer patients undergoing chemotherapy--report from the CONGO (complementary nursing in gynecologic oncology) study.

PURPOSE/OBJECTIVES: The purpose of this study was to develop a complex nursing intervention including complementary and alternative medicine (CAM) for breast and gynecologic cancer patients during chemotherapy to improve quality of life. METHODS: Data sources Theoretical framework and concepts, practical nursing knowledge, and evidence-based studies were compiled in interprofessional meetings. Data synthesis The final complex intervention consists of three autonomous, but interacting components: (1) CAM nursing package, (2) resource-oriented counseling, and (3) evidence-based information material on CAM. CAM interventions include acupressure, aromatherapy, compress, and massage, targeting 14 clinically relevant symptoms during chemotherapy. Participants receive these interventions during chemotherapy with instructions for self care. During a counseling interview, the patient's needs and preferences are assessed by trained nurses. Furthermore, participants are equipped with evidence-based information material (booklet and DVD). Prior to study start, nurses attended training modules for administering CAM therapies and for communicating and counseling within the salutogenic approach. CONCLUSIONS: It was possible to design a multimodal CAM nursing intervention based on a theoretical concept, evidence-based studies, and practical nursing experience targeting the prevention or relief of side-effects women suffer during chemotherapy. The systematic analysis of the CONGO study will contribute to evidence-based CAM nursing care within supportive cancer care. IMPLICATIONS FOR INTEGRATIVE CANCER CARE: Oncology nurses play an important role in supportive CAM care of breast and gynecologic cancer patients in daily clinical practice. Within oncology outpatient services, the implementation of evidence-based CAM nursing interventions and counseling may contribute to understand the impact of nursing on patient quality of life and symptom relief. This can lead to a new understanding of the nurse's professional role.

A complex nursing intervention of complementary and alternative medicine (CAM) to increase quality of life in patients with breast and gynecologic cancer undergoing chemotherapy: study protocol for a partially randomized patient preference trial.

BACKGROUND: Health-related quality of life (HRQoL) is most adversely affected in cancer patients between diagnosis and the end of chemotherapy. The aim of the Complementary Nursing in Gynecologic Oncology (CONGO) study is to assess the effectiveness of a complex nursing care intervention of CAM to increase HRQoL in cancer patients undergoing chemotherapy. METHODS/DESIGN: CONGO is a prospective partially randomized patient preference (PRPP) trial including adult women diagnosed with breast and gynecologic cancer starting a new chemotherapy regimen. Patients without strong preferences for CAM will be randomized to usual nursing care or complex nursing care; those patients with strong preferences will be allowed their choice. The intervention consists of three interacting and intertwined elements: CAM nursing intervention packet, counseling on CAM using a resource-oriented approach and evidence-based informational material on CAM. Primary outcome data on participants' HRQoL will be collected from baseline until the end of treatment and long-term follow-up using the EORTC-QLQ-C30. Secondary outcomes include nausea, fatigue, pain, anxiety/depression, social support, self-efficacy, patient competence, spiritual wellbeing, and satisfaction with care. Accompanying research on economic outcomes as well as a mixed-methods process evaluation will be conducted. A total of 590 patients (236 patients in the randomized part of the study and 354 patients in the observational part of the study) will be recruited in the two outpatient clinics. The first analysis step will be the intention-to-treat (ITT) analysis of the randomized part of the trial. A linear mixed model will be used to compare the continuous primary endpoint between the intervention and control arm of the randomized group. The observational part of the trial will be analyzed descriptively. External validity will be assessed by comparing randomized with nonrandomized patients. DISCUSSION: Cancer patients are increasingly using CAM as supportive cancer care, however, a patient-centered model of care that includes CAM for the patient during chemotherapy still needs to be evaluated. This protocol has been designed to test if the effects of the intervention go beyond potential benefits in quality-of-life outcomes.

Population pharmacokinetics of artesunate and dihydroartemisinin during long-term oral administration of artesunate to patients with metastatic breast cancer.

PURPOSE: The purpose of this study were firstly to characterize the population pharmacokinetics of artesunate (ARS) and its active metabolite dihydroartemisinin (DHA) in patients with metastatic breast cancer during long-term (>3 weeks) daily oral ARS administration and secondly to study the relationship between salivary and plasma concentrations of DHA. METHODS: Drug concentration-time data from 23 patients, receiving oral ARS (100, 150, or 200 mg OD), was analyzed using nonlinear mixed effects modeling. A combined drug-metabolite population pharmacokinetic model was developed to describe the plasma pharmacokinetics of ARS and DHA in plasma. Saliva drug concentrations were incorporated as being directly proportional to plasma concentrations. RESULTS: A first-order absorption model for ARS linked to a combined two-compartment disposition model for ARS and one-compartment disposition model for DHA provided the best fit to the data. No covariates were identified that could explain between-subject variability. A time-dependent increase in apparent elimination clearance of DHA was observed. Salivary DHA concentrations were proportionally correlated with total DHA plasma concentrations, with an estimated slope factor of 0.116. CONCLUSIONS: Population pharmacokinetics of ARS and DHA in patients with breast cancer was well described by a combined drug-metabolite model without any covariates and with an increase in apparent elimination clearance of DHA over time. The estimated DHA saliva/plasma ratio was in good agreement with the reported DHA unbound fraction in human plasma. Saliva ARS concentrations correlated poorly with plasma concentrations. This suggests the use of saliva sampling for therapeutic drug monitoring of DHA. However, further studies are warranted to investigate the robustness of this approach.

Resilience in infertile couples acts as a protective factor against infertility-specific distress and impaired quality of life.

OBJECTIVE: Our hypothesis was that resilience (=psychosocial stress-resistance) reduces infertility-specific distress and maintains quality of life of infertile couples. METHODS: Questionnaire data of WHO Quality of Life assessment (WHOQOL; domains: 'physical', 'psychological', 'social relationships' and 'environment'), Fertility Problem Inventory (FPI; scales: 'social concern', 'sexual concern', 'relationship concern', 'rejection of childfree lifestyle' and 'need for parenthood'), Resilience Scale (RS), as well as sociographic and medical data were available for 199 infertile couples. RESULTS: Age, medical diagnosis and 'intensity of desire for a child' had no influence on quality of life. High scores on 'suffering from childlessness' went along with less satisfaction on 'physical' and 'psychological' domains for the women only. For both partners, high scores on 'suffering from childlessness' went along with higher scores on all FPI scales. High resilience was associated with high scores on all WHOQOL domains for both partners, also with low scores on all FPI scales except for 'need for parenthood' for the women and with a low score only on 'relationship concern' for the men. CONCLUSIONS: For infertile couples, resilience can be considered as an unspecific protective factor against infertility-specific distress and impaired quality of life. When offering counselling to involuntarily childless couples, awareness should be raised for resilience as a couple's resource and a "generic" factor of coping.

[Complementary and alternative therapies for climacteric symptoms]. / Alternative Therapiemoglichkeiten im Klimakterium.

OBJECTIVE: Review on complementary and alternative therapies for climacteric symptoms. METHODS: Search for publications about complementary or alternative treatments for climacteric symptoms based on Cochrane Library and Medline (1966-2006) including the references from the identified clinical trials and reviews. RESULTS: Cimicifuga may influence climacteric symptoms, especially hot flushes. Results for phytoestrogens, hop and Salvia seem promising but are less convincing. St. John's wort is an option for the treatment of moderate depressive symptoms. Phytoestrogens seem to have some potential for the prevention of osteoporosis and cardiovascular diseases. Results for the influence of lifestyle on hot flushes are conflicting, but interventions have demonstrated their use for the prevention of osteoporosis and cardiovascular diseases. CONCLUSIONS: Lifestyle modifications, Cimicifuga and phytoestrogens may relieve climacteric symptoms. Phytoestrogens and Cimicifuga should not be given to breast cancer survivors.

Cortisol and cortisone in human follicular fluid and serum and the outcome of IVF treatment.

BACKGROUND: The glucocorticoid status of ovarian follicular fluid has been linked to oocyte quality. The aim of this study was to examine whether the concentrations of cortisone and cortisol and their calculated ratios in the follicular fluid and serum samples are predictive of IVF outcome. METHODS: In the prospective study of 387 patients (420 treatment cycles) undergoing IVF treatment the concentrations of cortisone and cortisol were measured with specific assays, and their calculated ratios in the follicular fluid and serum samples obtained after ovarian stimulation and induced ovulation were determined. RESULTS: In 75 patients, treatment resulted in clinical pregnancy and was associated with significantly lower follicular cortisone (24+/-12 versus 29+/-16 nmol/l, P<0.002) and higher cortisol/cortisone ratio (7.24+/-2.22 versus 6.45+/-2.17 nmol/l, P<0.007). In addition, the ratios of serum cortisone and cortisol to follicular cortisone and cortisol were significantly higher in those women who became pregnant. CONCLUSIONS: We propose that the follicular fluid glucocorticoid concentration resulting from the conditions in the circulation and the course of the intrafollicular cortisol-cortisone interconversion appear to play a role in the outcome of IVF.
