RESUMO

BACKGROUND: 5-Fluorouracil (FU) is one of the most commonly used cytostatic drugs in the systemic treatment of cancer. Treatment with FU may cause severe or life-threatening side effects and the treatment-related mortality rate is 0.2-1.0%. SUMMARY: Among other risk factors associated with increased toxicity, a genetic deficiency in dihydropyrimidine dehydrogenase (DPD), an enzyme responsible for the metabolism of FU, is well known. This is due to variants in the DPD gene (DPYD). Up to 9% of European patients carry a DPD gene variant that decreases enzyme activity, and DPD is completely lacking in approximately 0.5% of patients. Here we describe the clinical and genetic background and summarize recommendations for the genetic testing and tailoring of treatment with 5-FU derivatives. The statement was developed as a consensus statement organized by the German Society for Hematology and Medical Oncology in cooperation with 13 medical associations from Austria, Germany, and Switzerland. Key Messages: (i) Patients should be tested for the 4 most common genetic DPYD variants before treatment with drugs containing FU. (ii) Testing forms the basis for a differentiated, risk-adapted algorithm with recommendations for treatment with FU-containing drugs. (iii) Testing may optionally be supplemented by therapeutic drug monitoring.

RESUMO

PURPOSE: The present study aims to analyze a cohort of advanced breast cancer patients in Germany to assess their interest in complementary and alternative medicine (CAM) and patient's use of most frequent CAM methods. PATIENTS AND METHODS: Based on the PREGNANT real-time breast cancer registry which is a multicenter study in Germany, questionnaires of 580 patients with advanced breast cancer were evaluated. The implemented questionnaire for CAM asked for general interest in CAM and for patient's use of different CAM methods at present and in the past. The interest and application of CAM were analyzed for association with patients' characteristics such as tumor, patient, and therapy characteristics. RESULTS: In total, 436 out of 580 (75%) patients claimed to be interested in CAM. Further, interest in CAM is significantly correlated with younger age and absence of metastasis at the time of diagnosis. Multivariate analysis confirmed the patient's age and distant disease status at the time of diagnosis as related to interest in CAM. A total of 56.4% of patients applied any CAM method in the past. Moreover, with increasing lines of therapies, the more frequent use of CAM was observed. Hereby, praying, vitamin supplements, and other food supplements were most frequently applied. CONCLUSION: Our data demonstrate high overall interest and frequent use of CAM in advanced breast cancer patients supporting a strong demand of breast cancer patients for complementary counseling and treatments additional to the established cancer therapies. It is indispensable to implement counseling and evidence-based complementary treatments into clinical routine of cancer centers and to adapt postgraduate medical education, respectively.

RESUMO

PURPOSE: Chemotherapy with anthracyclines, taxanes, or alkylating agents often causes cutaneous side effects. Nonspecific inhibition of the proliferative activity of keratinocytes has antidifferentiation effects that lead to defects in the barrier function and, thus, to dry, itchy, and irritable skin. These cutaneous symptoms reduce the quality of life of the patients considerably. Conditioning with topical application of niacinamide uses the cytoprotective and barrier stabilizing effect of vitamin B3. PATIENTS AND METHODS: A multicenter randomized crossover study investigated the influence of the test preparation on the quality of life compared to standard care for 73 patients with breast cancer undergoing adjuvant or neoadjuvant cytostatic therapy. Primary target parameter was the Dermatology Life Quality Index with its respective subscales after 6 weeks of a twice-daily application of the respective preparations. Additionally, specific symptoms such as pruritus, dryness, and irritability have been assessed using visual analog scales. RESULTS: Regarding the total score of the Dermatology Life Quality Index, no relevant differences could be observed. However, the results for the "symptoms and feelings" subscale show a significant advantage in favor of the test preparation. Significant superiority of the test preparation could also be observed in the secondary target parameters, the visual analog scales (P<0.05). CONCLUSION: The results show for the first time a significant superiority of prophylactic application of niacinamide for maintaining quality of life while undergoing cytostatic treatment.

RESUMO

BACKGROUND: Evidence suggests that cytokines (IL-6) and alteration of the hypothalamic-pituitary-adrenal (HPA) axis play a crucial role in the etiology of depression. Patients with cancer show elevated prevalence rates for depression. The objective of this cross-sectional study was to investigate the associations between these abnormalities and depression. METHODS: Plasma concentrations of IL-6 and cortisol were measured in cancer patients with (N = 31) and without depression (N = 83). The relative diurnal variation of cortisol (cortisol VAR), expressed in percentage, was calculated. RESULTS: There was a significant difference in median plasma concentration of IL-6 between the patients with depression and those without (18.7 vs 2.7 pg/mL; P < .001). Relative cortisol VAR was decreased in depressed patients as compared with patients without depression (11.72% vs 60.6%, P = .037). A positive correlation between the depressive symptoms and IL-6 concentration was found (r = 0.469, P < .001). Negative correlations were found between cortisol VAR versus depressive symptoms and cortisol VAR versus IL-6 (r = -0.6, P < .001 and r = -0.52, P < .001, respectively). IL-6 (odds ratio [OR] = 1.1; 95% confidence interval [CI] = 1.0-1.2; P = .006) and cortisol VAR (OR = 1.3; 95%CI = 1.0-1.4; P = .02) are independently associated with depression. CONCLUSIONS: Depression in cancer is associated with increased plasma IL-6 concentrations and dysfunction of the HPA axis.

RESUMO

INTRODUCTION: In sequence to our first survey in 2004 on antihormonal therapy with aromatase inhibitors (AIs), we conducted a second survey on the prescription practice in 2005. MATERIAL AND METHODS: We distributed the anonymous questionnaires amongst the participants of the 2005 congresses of the German Society of Senology and German Society of Haematology and Oncology. RESULTS: The surveys were mostly completed by gynaecologists (46%) and medical oncologists (46%). According to the responses given, over 31,000 breast cancer patients were treated in these institutions in 2004, over 18,000 of whom received AIs. 37/30% of doctors prescribed AIs for national/private health insurance patients depending on the known risks of tamoxifen treatment (> 50% of cases). Whilst only 6/10% of doctors prescribed AIs for more than 50% of patients with either national/private health insurance in 2004, this figure reached 49% in 2005, independent of the type of medical insurance. Assuming unrestricted approval, 68/65% of doctors would treat over 50% of their patients with an AI. CONCLUSION: The rate of treatment with AIs has increased dramatically. The previous gold standard, tamoxifen, was by and large replaced by AIs in 2004/2005. We may assume that almost all receptor- positive breast cancer patients will receive an AI in the course of their adjuvant therapy in the very near future.

RESUMO

PURPOSE: To compare the effects of cannabis extract (CE), delta-9-tetrahydrocannabinol (THC), and placebo (PL) on appetite and quality of life (QOL) in patients with cancer-related anorexia-cachexia syndrome (CACS). PATIENTS AND METHODS: Adult patients with advanced cancer, CACS, weight loss (> or = 5% over 6 months), and Eastern Cooperative Oncology Group (ECOG) performance status (PS) < or = 2 were randomly assigned (2:2:1) to receive CE (standardized for 2.5 mg THC and 1 mg cannabidiol) or THC (2.5 mg) or PL orally, twice daily for 6 weeks. Appetite, mood, and nausea were monitored daily with a visual analog scale (VAS); QOL was assessed with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (composite score: questions 29 and 30). Cannabinoid-related toxicity was assessed every 2 weeks. RESULTS: Of 289 patients screened, 243 were randomly assigned and 164 (CE, 66 of 95 patients; THC, 65 of 100 patients; and PL, 33 of 48 patients) completed treatment. At baseline, groups were comparable for age (mean, 61 years), sex (54% men), weight loss (32% > or = 10%), PS (13% ECOG = 2), antineoplastic treatment (50%), appetite (mean VAS score, 31/100 mm), and QOL (mean score, 30/100). Intent-to-treat analysis showed no significant differences between the three arms for appetite, QOL, or cannabinoid-related toxicity. Increased appetite was reported by 73%, 58%, and 69% of patients receiving CE, THC, or PL, respectively. An independent data review board recommended termination of recruitment because of insufficient differences between study arms. CONCLUSION: CE at the oral dose administered was well tolerated by these patients with CACS. No differences in patients' appetite or QOL were found either between CE, THC, and PL or between CE and THC at the dosages investigated.

RESUMO

PURPOSE: The objective of this study was to evaluate the efficacy and tolerability of leuprorelin acetate in adjuvant treatment in comparison to standard chemotherapy with CMF in premenopausal, estrogen-receptor-positive or unknown, node-positive patients with early breast cancer. PATIENTS AND METHODS: The patients were randomly assigned to receive either 2 years of hormone ablation with leuprorelin acetate 11.25 mg as a subcutaneous injection every three months or six courses of CMF (cyclophosphamide 500 mg/m2, methotrexate 40 mg/m2, fluorouracil 600 mg/m2, days 1 and 8, q 4 weeks). The primary study end-point was recurrence-free survival (RFS) after 2 years. Secondary end-points included overall survival, adverse events and hormonal suppression. RESULTS: Between 1995 and 1999, a total of 589 patients with breast cancer were randomized to treatment with leuprorelin acetate or CMF. The data of 227 patients were available for this first interim analysis. One hundred and ten and 117 patients were assigned to leuprorelin acetate and chemotherapy, respectively. Both treatment arms were well balanced for baseline characteristics. So far, no difference between the groups has emerged with respect to recurrence-free or overall survivaL Suppression of serum estradiol levels and menstruation was less marked in the CMF-group compared to the leuprorelin arm. The most common adverse events were low-grade hot flushes, weight gain and increased sweating in the leuprorelin-treated patients and alopecia, nausea and vomiting in the CMF-group. CONCLUSION: According to these preliminary results, ovarian suppression with leuprorelin acetate was as effective as standard chemotherapy for premenopausal women with hormone-sensitive, node-positive early breast cancer.
