Dose finding study of granisetron in patients receiving high-dose cisplatin chemotherapy. The Granisetron Study Group.

The efficacy and safety of three different doses of granisetron (2 micrograms kg-1, group A; 10 micrograms kg-1, group B; 40 micrograms kg-1, group C) were compared in a randomised, double-blind study of 157 patients due to receive high-dose cisplatin therapy (mean dose > 97 mg m-2). In each group, up to two 3 mg rescue doses of granisetron were allowed if more than mild nausea or vomiting occurred. In group A 30.8%, in group B 61.5% and in group C 67.9% of patients were complete responders (i.e. no vomiting or nothing worse than mild nausea) during the first 24 h. These differences are significant between groups A and B, and A and C. There were no statistically significant differences in any efficacy variable between the 10 micrograms kg-1 and 40 micrograms kg-1 groups, although in each case the trend favoured the higher dose. Additional rescue doses resulted in resolved or improved symptoms in 95.3% for the first rescue dose and 93.3% for the second. Over the 7 days of the study, 82.7%, 82.7% and 86.8% of patients in groups A, B and C respectively were treated with granisetron alone. Headache was the most common side-effect, reported by 9.6% of patients; the majority of headaches were mild. There was no difference between the treatment groups regarding the adverse event rate. We concluded that prophylactic doses of 10 or 40 micrograms kg-1 lead to a safe and satisfactory degree of control of nausea and vomiting induced by high-dose cisplatin.     

The cardiovascular safety of high-dose intravenous granisetron in cancer patients receiving highly emetogenic chemotherapy

Objectives To assess the cardiovascular safety, tolerability and efficacy of high doses of granisetron for the treatment of nausea and vomiting in patients undergoing highly emetogenic chemotherapy.Methods Patients with histologically confirmed malignant disease were given an intravenous infusion of granisetron, 160 g/kg, over 30 min, starting 15 min after highly emetogenic chemotherapy. Patients underwent cardiac monitoring for 24 h following the granisetron infusion. Pulse, blood pressure and electrocardiogram (lead II and ambulatory) measurements were taken, and routine clinical chemistry and haematology tests performed. Blood samples for pharmacokinetic analysis were taken before the granisetron infusion, and at intervals afterwards. Adverse events were self-assessed using a symptom checklist. Self-assessment categorical rating scales were used to evaluate patient nausea, vomiting and retching.Results Ten patients (eight females and two males; average age 41.5 years) completed the trial and were included in the safety and efficacy assessments. No clinically relevant changes in electrocardiogram, pulse rate, blood pressure or laboratory parameters were observed. Furthermore, in the 7 days following dosing there were no serious adverse events leading to withdrawal from the trial. A complete response (no vomiting, retching or, at most, mild nausea) was experienced by five patients. Six patients had no, or mild, nausea and an additional two patients vomited on a maximum of two occasions. Additional antiemetic rescue medication was given to three patients during the 24-h trial period. Despite considerable interpatient variability, C_max and AUC parameters were proportionally greater than values reported for lower doses of granisetron.Conclusions Granisetron administered at four times the upper recommended dose demonstrated good efficacy and tolerability with no clinically important cardiac effects.     

The effects of ondansetron and granisetron on electrocardiography in children receiving chemotherapy for acute leukemia

5-HT3 receptor antagonists, including granisetron and ondansetron, are widely used in the prophylactic treatment of chemotherapy-induced nausea and vomiting. Although the cardiac safety of granisetron and ondansetron has been investigated in several adult studies, there is no report investigating the effects of those agents on electrocardiography (ECG) in children. The effects of intravenously infused (over 30 seconds) 0.1 mg/kg ondansetron and 40 microg/kg granisetron on ECG were assessed in 22 children receiving high-dose methotrexate therapy for acute lymphoblastic leukemia. The ECG recording was obtained at before and just after the infusion, and repeated at 1, 3, 6, and 24 hours of treatment. Granisetron administration resulted in a statistically significant decrease of mean heart rate at 1 and 3 hours, and significant prolongation of mean QT and QTc dispersions at 1 hour of infusion. In patients treated with ondansetron, no meaningful change was observed. In conclusion, intravenous granisetron but not ondansetron causes clinically asymptomatic and transient changes on ECG measurements in children receiving high-dose methotrexate therapy.     

Clinical usefulness of ondansetron injection in patients receiving cancer chemotherapy

Before and after launch of 5-HT3, antagonist, necessary dose and duration of chemotherapy were compared between the patients who were confirmed to have undergone chemotherapy before the launch of 5-HT3 antagonist (retrospective group) and the ones currently using ondansetron (OND) for chemotherapy-induced emesis (prospective group). Clinical usefulness of OND was evaluated through survey on quality of life (QOL) to patients and questionnaires to physicians, nurses & patients. Necessary dose of chemotherapy was evaluated by investigating actual dose of cisplatin (CDDP). As the result, necessary dose of CDDP was confirmed to be different between retrospective and prospective groups. The influence on the actual CDDP dose was observed with or without use of G-CSF or by recommended dose of CDDP, while no influence by 5-HT3 antagonist was observed. For necessary duration of chemotherapy, significant difference was not observed between retrospective or prospective groups. On the other hand, actual CDDP dose or necessary duration of chemotherapy were confirmed to be greatly affected by chemotherapy-induced adverse events such as blood disorder (e.g. bone marrow suppression) or renal disorder, rather than chemotherapy-induced emesis. As the result of QOL survey to patients and other questionnaires to medical staff & patients, the fact of chemotherapy-induced emesis to lower the patient's QOL as well as the importance of emetic control was confirmed. It was also confirmed that the workload of nurses or other medical staff has lessened since the launch of 5-HT3 antagonists.     

Randomized, placebo-controlled trial of Saforis for prevention and treatment of oral mucositis in breast cancer patients receiving anthracycline-based chemotherapy

BACKGROUND: Oral mucositis (OM) is a frequent complication of mucotoxic cancer therapy, causing significant oral pain, increased infection risk, and impaired functioning. The efficacy and safety of Saforis (glutamine) powder in UpTec for oral suspension was evaluated for the prevention and treatment of OM. METHODS: Three hundred twenty-six patients developing World Health Organization (WHO) grade >or=2 OM during a chemotherapy screening cycle were randomized to Saforis (n = 163) or placebo (n = 163) 3 times/day during their next chemotherapy cycle (Treatment Cycle 1). Patients were crossed over to the alternate treatment during Treatment Cycle 2. As prespecified in the statistical plan, because of a carryover effect in Treatment Cycle 2 the primary efficacy analysis was based on Treatment Cycle 1 only. RESULTS: Compared with placebo, Saforis significantly reduced the incidence of clinically significant WHO grade >or=2 OM (38.7% vs. 49.7%; P = .026) and severe WHO grade >or=3 OM (1.2% vs. 6.7%; P = .005) in Treatment Cycle 1. Saforis also significantly reduced the worst Oral Mucositis Assessment Scale ulceration score in Treatment Cycle 1 compared with placebo (mean, 0.23 +/- 0.39 vs. 0.32 +/- 0.45; P = .013). Patients receiving Saforis in Treatment Cycle 1 had a lower-than-expected OM incidence when crossed over to placebo in Treatment Cycle 2, indicating a significant carryover effect (P = .027). The incidence of treatment-emergent adverse events was similar between groups. CONCLUSIONS: Saforis is safe and effective for preventing and treating OM in patients receiving mucotoxic cancer chemotherapy.     

Endocrine profile in breast cancer patients receiving chemotherapy.

Cyclophosphamide and other alkylating agents suppress ovarian function in pre-menopausal women. However, endocrine details remain unknown regarding the influence of patients' age and obesity on CMF-induced hormonal changes. We studied changes in endocrine profile due to chemotherapy (CMF) in 70 pre-menopausal patients with axillary node positive, stage II and/or III breast carcinoma. Plasma levels of estrone (E1), estradiol (E2), androstenedione (A2), luteinizing hormone (LH), and prolactin (PRL) were determined on day 1 and 8 of each chemocycle for 12 cycles. After receiving therapy, 23% of the women continued to have regular menstrual cycles (non-amenorrheic group). In the remaining 77%, ovarian function was suppressed, as evidenced by the onset of amenorrhea within 0-11 months (amenorrheic group). The mean time to amenorrhea was 2.83 +/- 0.33 months (SE). The time required to develop amenorrhea inversely correlated to the patient's age. Both incidence of amenorrhea and time to amenorrhea remained unaffected by either patient's obesity or the timing of chemotherapy initiation in relation to menstrual cycle phase (progestational, follicular). Plasma hormone levels fluctuated widely in both groups during the first three chemocycles. During chemocycle months 4 to 10, in the amenorrheic group, plasma E1, E2, and P declined to their baseline levels with a concomitant rise in LH levels. At this time, E1, E2, and P levels were significantly lower in amenorrheics, despite menstrual cycle associated fluctuations in the non-amenorrheic group. Estrogens (E1 and E2) gradually declined further following the onset of amenorrhea in subsequent months. Further data analysis suggests that host age or obesity did not influence CMF-induced changes in the plasma endocrine profile.     

Phase III double-blind comparison of intravenous ondansetron and metoclopramide as antiemetic therapy for patients receiving multiple-day cisplatin-based chemotherapy.

BACKGROUND. Ondansetron hydrochloride is a selective serotonin subtype 3 (5HT3) receptor antagonist that has been shown to be an effective antiemetic in patients receiving cisplatin chemotherapy. METHODS. This double-blind study compared the safety and efficacy of intravenous ondansetron with metoclopramide in patients receiving a 4- or 5-day regimen of cisplatin (20-40 mg/m2/day) combination chemotherapy. Forty-five patients were enrolled, and efficacy of the drug therapy could be studied for all 45. Patients were randomly assigned (1:1) to receive three daily intravenous doses of either 0.15 mg/kg ondansetron or 1 mg/kg metoclopramide. All patients were monitored daily for the number of emetic episodes (vomiting or retching), severity of nausea, adverse events, and laboratory safety parameters. RESULTS. Seven (30%) patients who received ondansetron had no emetic episodes throughout the entire study period compared with two (9%) who received metoclopramide (P = 0.077). The greatest difference in antiemetic efficacy was seen on day 1, when 18 (78%) patients who received ondansetron had no emetic episodes compared with 3 (14%) patients who received metoclopramide (P < 0.001). Significantly fewer antiemetic treatment failures (more than five emetic episodes or withdrawal from the study) occurred with patients given ondansetron (9%) than with those given metoclopramide (50%) during the entire study period (P = 0.002). The most commonly reported adverse event associated with ondansetron therapy was headache (controlled with acetaminophen), whereas diarrhea and restlessness were the most commonly reported adverse events associated with metoclopramide therapy. Extrapyramidal symptoms were judged to have occurred in 13 patients who received metoclopramide and 1 patient who received ondansetron. However, the patient who received ondansetron subsequently was judged to have had an anxiety attack. In patients with low or normal baseline transaminase values, a greater percentage who received ondansetron had transient increases as great as twice the upper limit of normal in aspartate transaminase (5% versus 0%) and alanine transaminase (17% versus 6%) than those who received metoclopramide. CONCLUSIONS. Ondansetron is superior to metoclopramide as antiemetic therapy for multiple-day cisplatin-based chemotherapy.     

Cognitive function in breast cancer patients receiving adjuvant chemotherapy.

PURPOSE: Breast cancer patients receiving chemotherapy have complained of difficulties in their ability to remember, think, and concentrate. This study assessed whether there are differences in cognitive function between breast cancer patients treated with standard-dose adjuvant chemotherapy compared with healthy controls. PATIENTS AND METHODS: The High Sensitivity Cognitive Screen and the Profile of Mood States (POMS) were used to assess cognitive function and mood in a group of 107 women. The women consisted of 31 breast cancer patients receiving adjuvant chemotherapy (group A), 40 breast cancer patients who had completed adjuvant chemotherapy a median of 2 years earlier (group B), and 36 healthy controls (group C). RESULTS: Univariate analysis showed statistically significant differences (P =.009) in overall cognitive function scores between groups A and C, with poorer function in patients receiving adjuvant chemotherapy. These differences remained significant (P =.046) when controlling for age, education level, and menopausal status. More patients had moderate or severe cognitive impairment in groups A and B than in controls (P 相似文献   

Endocrine profile in breast cancer patients receiving chemotherapy

Summary Cyclophosphamide and other alkylating agents suppress ovarian function in pre-menopausal women. However, endocrine details remain unknown regarding the influence of patients' age and obesity on CMF-induced hormonal changes. We studied changes in endocrine profile due to chemotherapy (CMF) in 70 pre-menopausal patients with axillary node positive, stage II and/or III breast carcinoma. Plasma levels of estrone (E1), estradiol (E2), androstenedione (A2), luteinizing hormone (LH), and prolactin (PRL) were determined on day 1 and 8 of each chemocycle for 12 cycles. After receiving therapy, 23% of the women continued to have regular menstrual cycles (non-amenorrheic group). In the remaining 77%, ovarian function was suppressed, as evidenced by the onset of amenorrhea within 0–11 months (amenorrheic group). The mean time to amenorrhea was 2.83±0.33 months (SE).

Granisetron plus or minus alprazolam for emesis prevention in chemotherapy of lymphomas: a randomized multicenter trial. Granisetron Trialists Group.

Anxiety can increase the risk of chemotherapy related emesis. We have studied the role of a benzodiazepine (alprazolam: A) in addition to granisetron for controlling emesis in patients treated with moderately emetogenic chemotherapy for malignant lymphomas according to an anxiety scale (Covi score). Two hundred twenty-five patients receiving at least 3 cycles of chemotherapy including adriamycin and/or cyclophosphamide and/or epirubicin and/or dacarbazine were randomized. Patients in arm G (n = 111) received 3 mg i.v. granisetron 10 min before chemotherapy at cycles (C) 1, 2 and 3 while in arm G+A (n = 114), alprazolam (A) was added per os 1 mg 1 hour before chemotherapy (H-1) and 0.5 mg at H+6 for C1. At C2 and C3, A was given 0.75 or 1.5 mg at H-48, H-24, H-1 and 0.5 mg at H+6. Patients characteristics were comparable between the 2 arms. Complete response rates (i.e. no emesis or at least slight nausea) were similar in both arms: G: 83, 94 and 93% versus G+A: 89, 93 and 97% in C1, C2 and C3 respectively. Nevertheless, the Covi score of the population was low rendering difficult the study of the factor "anxiety". Somnolence was significantly more frequent in the G+A arm (p < 0.0001).     

Paclitaxel-induced peripheral neuropathy in patients receiving adjuvant chemotherapy for breast cancer

Background

The long-term outcomes and risk factors of paclitaxel-induced peripheral neuropathy (PIPN) have not yet been fully elucidated.

Methods

We identified 219 breast cancer patients who received paclitaxel as adjuvant chemotherapy between 2002 and 2009. We retrospectively analyzed the incidence, time to onset, duration, and risk factors for PIPN by chart review.

Results

Of the 219 patients, 212 developed PIPN (97%) during a median follow-up time of 57 months (range 5.3–95.5). Median time to PIPN onset was 21 days (range 11–101) for the entire patient population: 35 days (range 14–77) for weekly administration and 21 days (range 11–101) for tri-weekly administration. PIPN caused termination of paclitaxel treatment in 7 patients (4%). Median duration of PIPN was 727 days (range 14–2621 days). PIPN persisted in 64 and 41% of patients at 1 and 3 years after initiating paclitaxel, respectively. Age ≥60 years and severity of PIPN were significantly associated with PIPN duration.

Conclusions

PIPN persists longer in older patients and in those who experience severe neuropathy. Further studies to identify the risk factors for PIPN are warranted.     

A randomized study of aprepitant, ondansetron and dexamethasone for chemotherapy-induced nausea and vomiting in Chinese breast cancer patients receiving moderately emetogenic chemotherapy

Objectives This is a single center, randomized, double-blind placebo-controlled study to evaluate the NK(1)-receptor antagonist, aprepitant, in Chinese breast cancer patients. The primary objective was to compare the efficacy of aprepitant-based antiemetic regimen and standard antiemetic regimen for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients who received moderately emetogenic chemotherapy. The secondary objective was to compare the patient-reported quality of life in these two groups of patients. Patients and Methods Eligible breast cancer patients were chemotherapy-naive and treated with adjuvant AC chemotherapy (i.e. doxorubicin 60 mg/m² and cyclophosphamide 600 mg/m²). Patients were randomly assigned to either an aprepitant-based regimen (day 1, aprepitant 125 mg, ondansetron 8 mg, and dexamethasone 12 mg before chemotherapy and ondansetron 8 mg 8 h later; days 2 through 3, aprepitant 80 qd) or a control arm which consisted of standard regimen (day 1, ondansetron 8 mg and dexamethasone 20 mg before chemotherapy and ondansetron 8 mg 8 h later; days 2 through 3, ondansetron 8 mg bid). Data on nausea, vomiting, and use of rescue medication were collected with a self-report diary, patients quality of life were assessed by self-administered Functional Living Index-Emesis (FLIE). Results Of 127 patients randomized, 124 were assessable. For CINV in Cycle 1 AC, there was no significant difference in the proportion of patients with reported complete response, complete protection, total control, ‘no vomiting’, ‘no significant nausea’ and ‘no nausea’. The requirement of rescue medication appears to be lesser in patients treated with the aprepitant-based regimen compared to those with the standard regimen (11% vs. 20%; P = 0.06). Assessment of FLIE revealed that while there was no difference in the nausea domain and the total score between the two groups; however, patients receiving standard antiemetic regimen had significantly worse quality of life in the vomiting domain (mean score [SD] = 23.99 [30.79]) when compared with those who received the aprepitant-based regimen (mean score [SD] = 3.40 [13.18]) (P = 0.0002). Both treatments were generally well tolerated. Patients treated with the aprepitant-based regimen had a significantly lower incidence of neutropenia (53.2% vs. 35.5%, P = 0.0468), grade ≥ 3 neutropenia (21.0% vs. 45.2, P = 0.0042) and delay in subsequent cycle of chemotherapy (8.1% vs. 27.4%, P = 0.0048). Conclusion The aprepitant regimen appears to reduce the requirement of rescue medication when compared with the control regimen for prevention of CINV in patients receiving both an anthracycline and cyclophosphamide, and is associated with a better quality of life during adjuvant AC chemotherapy.     

Prevalence and course of fatigue in breast cancer patients receiving adjuvant chemotherapy.

BACKGROUND: The purpose of this study was to determine the prevalence of fatigue and the course of fatigue as a function of chemotherapy in breast cancer patients undergoing adjuvant chemotherapy. PATIENTS AND METHODS: In a prospective cohort study, a sample of 157 patients with breast cancer were interviewed, using the Rotterdam Symptom Checklist and the Multidimensional Fatigue Inventory, at the first, third and fifth cycle of adjuvant chemotherapy, as well as 4 and 12 weeks after the last cycle of adjuvant chemotherapy. Patients were treated with either a doxorubicin-containing schedule, or cyclophosphamide, methotrexate and 5-fluorouracil (CMF). RESULTS: The courses of general and physical fatigue are to a large extent similar. After the last cycle of chemotherapy, the CMF group reported a significant increase in fatigue, which was followed by a significant reduction. In the doxorubicin group a significant increase in fatigue was only seen during the first cycles of chemotherapy. The fatigue experienced at the first and the last measurements do not differ significantly. CONCLUSIONS: The prevalence of fatigue increased significantly after the start of chemotherapy. After chemotherapy treatment the prevalence rate seemed to decline. A different impact of chemotherapy on the course of fatigue was found. In the doxorubicin group a direct increase in fatigue was found. In the CMF group a moderate direct increase occurred, followed by a delayed strong increase. An increase in fatigue was associated with a decrease in daily functioning. At all measurement occasions fatigue was affected by type of operation, such that women with a mastectomy were more fatigued than women that underwent a lumpectomy. Receiving radiotherapy also led to an increase in fatigue. With this knowledge breast cancer patients can be better informed about what they can expect. Further research should include interventions addressing how to reduce or cope with fatigue during as well as after receiving adjuvant chemotherapy.     

A randomized open-label parallel-group study comparing ondansetron with ondansetron plus dexamethasone in patients with metastatic breast cancer receiving high-dose epirubicin. A Hellenic Cooperative Oncology Group study

AIMS AND BACKGROUND: The purpose of this multicenter randomized, open-label, parallel-group study was to assess whether the addition of low-dose dexamethasone to ondansetron results in improved control of chemotherapy-induced emesis in patients undergoing first-line chemotherapy with high-dose epirubicin. METHODS & STUDY DESIGN: Patients were randomized to receive either 24 mg of ondansetron or 24 mg of ondansetron plus 8 mg of dexamethasone administered as an intravenous infusion 30 minutes prior to administration of chemotherapy. Both groups of patients received 8 mg of ondansetron given orally from day 2 to 5 two times daily. Fifty-three patients received ondansetron and 50 received ondansetron plus dexamethasone. The patients recorded nausea and the number of vomits and retches daily on diary cards. RESULTS: Significantly more patients in the ondansetron plus dexamethasone group experienced neither vomiting nor retching during the first day of the first course of chemotherapy compared to those receiving ondansetron alone (79.6% vs 53.8%, P = 0.0062). Furthermore, there was a trend in favor of ondansetron plus dexamethasone in the control of nausea. There was no statistically significant difference between ondansetron plus dexamethasone versus ondansetron alone in protecting patients from emesis between days 2 and 5 of the first course of chemotherapy (66.7% vs 62.7%, P = 0.68). This was probably due to the small sample size. Ondansetron was well tolerated, with 15 patients (15%) reporting adverse events such as headache or constipation. CONCLUSIONS: It appears that ondansetron given intravenously in combination with dexamethasone is more effective than ondansetron alone in the control of acute emesis in patients undergoing their first course of chemotherapy with high-dose epirubicin. No difference between the regimens was found with regard to nausea and delayed emesis control.     

Incidence of anaemia in breast cancer patients receiving adjuvant chemotherapy

Anaemia is frequent in breast cancer patients but often remains undiagnosed and untreated. To determine the incidence of anaemia a prospective survey of primary non-metastatic breast cancer patients who received at least four cycles of adjuvant, non-platinum multi-agent chemotherapy was conducted at 47 centres in Austria. Two hundred and forty seven patients were prospectively included between October 1999 and December 1999. Haemoglobin (Hb) levels were determined after surgery and prior to each cycle of chemotherapy. Treatment of anaemia (blood transfusion or epoetin alfa) during the observation period was at the physician's discretion. For the purpose of this study, patients were considered to be anaemic if their Hb was below 12 g/dl. At baseline (after surgery and before the first cycle of chemotherapy), 28.7% of all patients were anaemic. The only significant differentiating factor was the type of surgery. 37.9% of patients who underwent mastectomy were anaemic, whereas only 22.8% of patients who underwent breast conserving surgery were anaemic. Forty two percent of 176 patients with a Hb level of 12 g/dl at baseline developed anaemia during adjuvant chemotherapy. The only factor that significantly influenced the development of anaemia during chemotherapy was the Hb level at baseline. The total incidence of anaemia in patients with primary breast cancer who underwent surgery followed by adjuvant multi-agent chemotherapy was 58.7%. Forty nine patients (20.2%), 48 patients (19.2%) and 48 patients (19.2%) showed a decrease in Hb levels by 1 g/dl, 1–2 g/dl and >2 g/dl, respectively. Only 18.6% of the patients who were found to be anaemic received anaemia treatment. The two most important factors for developing anaemia are the kind of surgery and the Hb level prior to chemotherapy.     

High incidence-rate of oral mucositis in breast cancer patients receiving anthracycline-based chemotherapy (FEC100)

Background: Oral mucositis is a frequent complication, but is poorly studied among patients with solid tumors. The purpose of this study is to clarify the incidence rate of oral mucositis in Japanese breast cancer patients receiving anthracycline-based chemotherapy(FEC100). Methods: From June 2007 to July 2008, 61 breast cancer patients eligible for this study received anthracycline-based chemotherapy(FEC100: 5-FU 500mg/m / / 2, epirubicin 100 mg/m2, cyclophosphamide 500 mg/m2)at National Kyushu Cancer Center and Iwate Medical University Hospital. The incidence rate and grade of oral mucositis were evaluated in these patients. Results: The cumulative incidence of oral mucositis was about 50%. Episodes of oral mucositis were more common during courses with febrile neutropenia than during courses without it(75. 0% vs 44. 9%, p=0. 12). The reduction of oral mucositis was only 13. 6% after administering the steroidal ointment and/or mouthwash, including sodium azulene sulfonate. Conclusions: New methods are needed to prevent and treat oral mucositis in patients receiving anthracycline- based chemotherapy(FEC100).     

Course of mental fatigue and motivation in breast cancer patients receiving adjuvant chemotherapy.

BACKGROUND: The purpose of this study is to determine the course of fatigue referring to cognitive symptoms (scale 'mental fatigue') as well as the motivation to start any activity (scale 'reduced motivation'), as a function of chemotherapy, in breast cancer patients undergoing adjuvant chemotherapy. PATIENTS AND METHODS: In a prospective cohort study a sample of 157 patients with breast cancer was interviewed at the first, third and fifth cycle of adjuvant chemotherapy as well as 4 and 12 weeks after completion of adjuvant chemotherapy. Patients were treated with standard adjuvant chemotherapy, either a doxorubicin containing schedule or CMF (cyclophosphamide, methotrexate and fluorouracil). The psychological dimensions of fatigue were measured by the Multidimensional Fatigue Inventory. A linear multilevel model was used for analysing the courses. RESULTS: The course of mental fatigue and motivation were not affected by the type of chemotherapy. The course of mental fatigue and motivation varied, but seemed to be stable during the treatment of chemotherapy. After the completion of chemotherapy, a weak improvement was seen. Relatively many patients experienced depressive symptoms during the study. These symptoms were correlated with both dimensions of fatigue. At all measurements mental fatigue was influenced by type of operation where women with a mastectomy were significantly more mentally fatigued than women that had undergone a lumpectomy, but nevertheless they were significantly more motivated to start any activity. Age, marital status, number of treatments and the interval between the operation and the first treatment of chemotherapy also seemed to be important determinants. CONCLUSIONS: An unequivocal pattern of mental fatigue and reduced motivation during as well as after adjuvant chemotherapy was not found. Depressive symptoms were definitely related to these variables. Type of operation had a significant impact on mental fatigue and motivation to start any activity. Health care providers should be aware of the high rate of patients who experience depressive symptoms during and after the treatment of chemotherapy. Further research should include the trajectory preceding adjuvant chemotherapy and a longer study period afterwards. Moreover, the exact influence of the variables 'age', 'marital status', 'number of treatments' and 'the interval between the operation and the first treatment of chemotherapy' on fatigue is unclear and needs further study.
