A descriptive study was conducted on self-reported symptoms and self-care by 37 adults receiving chemotherapy primarily for leukemia, lymphomas, or breast cancer or radiation therapy for head and neck or lung cancers. The Therapy-Related Symptom Checklist and demographic and interview forms on self-care for identified symptoms were used. Severe symptoms on the Therapy-Related Symptom Checklist subscales fatigue, eating, nausea, pain, numbness in fingers/toes, hair loss, and constipation were reported by patients on chemotherapy. Those on radiation therapy reported severe symptoms on the eating, fatigue, skin changes, oropharynx, and constipation subscales.Self-care strategies were in the following categories, using complementary medicine as framework: diet/nutrition/lifestyle change (eg, use of nutritional supplements; modifications of food and of eating habits; naps, sleep, and rest); mind/body control (eg, relaxation methods, prayer, music, attending granddaughter's sports events); biologic treatments (vitamins); herbal treatments (green mint tea); and ethnomedicine (lime juice and garlic). The first category was predominantly used by patients in both treatment types. Medications were prescribed also to help control symptoms (eg, pain and nausea). Symptom monitoring and self-care for symptoms identified may be facilitated by the Therapy-Related Symptom Checklist; based on reported symptom severity, care providers may prioritize interventions. A larger study needs to be done on (a) the use of the Therapy-Related Symptom Checklist as a clinical tool to assess symptoms that oncology patients experience during therapy; (b) whether care providers, based on patient-reported symptom severity, can prioritize interventions--and how this influences the efficiency of care; (c) the self-care strategies used by patients on chemotherapy or radiation therapy or both; and (d) how useful these strategies are in alleviating symptoms.

A Simplified Chinese version of the EORTC QLQ-BR53 was evaluated using responses from 233 patients with breast cancer in China by assessing the construct and criterion-related validity, internal consistency and test-retest reliability, and responsiveness as measured by score changes of the scales. Internal consistency reliability measured by Cronbach's coefficient alpha is greater than 0.75 for most multi-item scales except cognitive functioning (0.41) and breast symptoms (0.71). Test-retest reliability coefficients for all domains are greater than 0.80 with the exception of physical functioning (0.65), social functioning (0.75), appetite loss (0.75), diarrhea (0.72), and body image (0.72). Correlation and factor analysis among domains and items showed good construct validity for both QLQ-C30 and QLQ-BR23. Score changes over time were observed in most domains except emotional functioning, global health status/QOL, dyspnoea, constipation, diarrhea, financial difficulties, sexual functioning, sexual enjoyment, and breast symptoms. Therefore, the Simplified Chinese version of QLQ-BR53 shows reasonable validity, reliability, and responsiveness and can be used to measure QOL for Chinese patients with breast cancer.

The objective of this study was to evaluate the scientific evidence on flaxseed, including expert opinion, folkloric precedent, history, pharmacology, kinetics/dynamics, interactions, adverse effects, toxicology, and dosing. Electronic searches were conducted in 9 databases, 20 additional journals (not indexed in common databases), and bibliographies from 50 selected secondary references. No restrictions were placed on the language or quality of the publications. All literature collected pertained to efficacy in humans, dosing, precautions, adverse effects, use in pregnancy/lactation, interactions, alteration of laboratory assays, and mechanisms of action. Standardized inclusion/exclusion criteria are used for selection. Grades were assigned using an evidence-based grading rationale. A review of the literature on flaxseed yielded 13 categories for which flaxseed had been studied in humans, including constipation/laxative, attention-deficit hyperactivity disorder, hyperlipidemia, atherosclerosis/coronary artery disease, breast cancer, cyclic mastalgia (breast pain), menopausal symptoms, hyperglycemia/diabetes, hypertension, lupus nephritis, human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), and prostate cancer. Most of the available evidence investigates the efficacy of alpha-linoleic acid found in flaxseed compared with fish oil, and almost all of the available studies are poor quality. Although flaxseed and flaxseed oil have several promising future uses, the available literature does not support recommendation for any condition at this time.

Vinorelbine and mitoxantrone have both been demonstrated to have significant antitumor activity in patients with breast cancer. The aim of this study was to evaluate the efficacy and safety of the combination as second or third line treatment in patients with metastatic breast cancer (MBC). Fifty-one previously treated patients with MBC were enrolled from October 2001 to May 2004 and 48 were eligible for evaluation. Median age was 59 years (range 33-82) and ECOG performance status was < or =2. Distant sites of metastasis were as follows: liver 64%, bone 49%, lung 36%, lymph nodes 6%, skin 4%, brain 2% and other sites 6%. All patients received vinorelbine 20 mg/m(2), D1+8 and mitoxantrone 10 mg/m(2) D8 every 21 days for 6 cycles. All eligible patients were analyzed for toxicity and response. Two patients (4%) achieved complete response and 12 (25.5%) partial response. The objective overall response rate was 29.5% (95% confidence interval [CI] 17 - 45), 9 (19%) patients had stable disease, 17 (36%) had progressive disease and 7 (15%) were non-evaluable. After a median follow up of 18 months, overall survival was 13 months (range 0.8 - 38+) and median time to disease progression was 5 months (range 1 - 32). A total of 280 cycles was delivered. The relative dose intensities of mitoxantrone and vinorelbine were 79% and 77%, respectively. Toxicities (grade III-IV) were as follows: leukopenia 18 (38%), neutropenia 21 (45%), thrombocytopenia 1 (2%), anemia 4 (8.5%), alopecia 2 (4%) and constipation 1 (2%). Febrile neutropenia was recorded in one patient. There were no treatment related deaths. The combination of mitoxantrone and vinorelbine is an effective regimen with manageable toxicity in pretreated patients with advanced breast cancer.

Within an ongoing multicentre phase 3 randomised trial (ELDA, cancertrials.gov ID: NCT00331097), early breast cancer patients, 65-79 years old, with average to high risk of recurrence, are randomly assigned to receive CMF (cyclophosphamide 600 mg/m2, methotrexate 40 mg/m2, fluorouracil 600 mg/m2, days 1-8) or docetaxel (35 mg/m2 days 1-8-15), every 4 weeks. Here we report an unplanned safety analysis prompted by an amendment introducing creatinine clearance as a tool to adjust methotrexate dose. Before such change, 101 patients with a median age of 70 were randomly assigned CMF (53 patients) or docetaxel (48 patients). At least one grades 3-4 toxic event of any type was reported in 40 (75.5%) and 19 (39.6%) patients with CMF and docetaxel, respectively (p=0.0002). Grades 3-4 hematological events were observed in 37 (69.8%) vs. 4 (8.3%) cases (p<0.0001) and grades 3-4 non-hematological toxicity in 12 (22.6%) vs. 15 (31.2%) patients (p=0.11), with CMF and docetaxel, respectively. A higher incidence of anemia, neutropenia, thrombocytopenia and febrile neutropenia was reported with CMF. Constipation, mucositis, nausea and vomiting were more common with CMF; diarrhoea, abdominal pain, dysgeusia, neuropathy and liver toxicity were more frequent with docetaxel. No significant interaction was found between the occurrence of severe toxicity and baseline variables, including creatinine clearance and geriatric activity scales. In conclusion, weekly docetaxel appears to be less toxic than CMF in terms of hematological toxicity.

The purpose of the present study was twofold: first, to describe changes of Health-Related Quality of Life (HRQoL) during the adjuvant treatment among postmenopausal women with breast cancer; second, in the same population to identify the best predictors of Overall Quality of Life (QoL) after treatment, from perceived functioning, symptoms, emotional distress and clinical/demographic variables measured at baseline. The study group was 150 women (> or = 55 years of age) scheduled for adjuvant chemotherapy (CT, n=75) or radiotherapy (RT, n=75). They were examined before (baseline), during and after completing the treatment. Data about QoL, perceived functioning, symptoms and emotional distress were collected with the European Organisation for Research and Treatment of Cancer (EORTC)-QLQ-C30, BR23 and Hospital Anxiety and Depression Scale (HADS) questionnaires. The general finding was that the adjuvant treatments were associated with decrease in overall QoL, physical and role functioning, anxiety and body image, as well as with increase in fatigue, dyspnoea, pain, nausea/vomiting, constipation and systemic therapy side effects measured over time. For women receiving CT, better emotional functioning and less pain at baseline predicted better overall QoL at the end of the treatment. For women receiving RT, better physical and emotional functioning, less breast symptoms and lower tumour stage at baseline predicted better overall QoL at the end of the treatment.

We performed this study to examine the prevalence and correlates of fatigue and depression, and their relevance to health-related quality of life in disease-free breast cancer survivors. A total of 1,933 breast cancer survivors recruited from five large hospitals in Korea completed a mailed survey, which included the Brief Fatigue Inventory, Beck Depression Inventory, European Organization for Research and Treatment of Cancer QLQ-C30, and QLQ-BR23. With a framework that included sociodemographic, clinical, and symptom characteristics, multivariate logistic regression models were used to identify factors associated with fatigue and depression. Among breast cancer survivors, 66.1% reported moderate to severe fatigue and 24.9% reported moderate to severe depression. Risk factors common to both fatigue and depression were lower income, dyspnea, insomnia, appetite loss, constipation, and arm symptoms. Risk factors for fatigue only included younger age, employment, presence of gastrointestinal disease, and pain. Having a musculoskeletal disease was identified as a risk factor for depression only. Both fatigue and depression were influenced by sociodemographic factors, comorbidity and symptom characteristics rather than cancer or treatment-related factors. Both fatigue and depression were negatively associated with survivors' health-related quality of life. However, the patterns of differences in health-related quality of life according to severity of fatigue or depression were similar. This concurrent examination of risk factors for fatigue and depression may be helpful in the development of clinical management strategies in disease-free breast cancer survivors.

The NEAT trial reported considerable benefit for ECMF (epirubicin followed by cyclophosphamide, methotrexate and 5-fluorouracil) of 28% for relapse-free survival (RFS) and 30% for overall survival (OS), when compared with classical CMF in early breast cancer. To assess tolerability, toxicity, dose intensity and quality of life (QoL) analyses were undertaken. All 2021 eligible patients had common toxicity criteria (CTC), delivered chemotherapy and supportive treatments details and long-term morbidities recorded. The QoL substudy used multiple validated measures. ECMF produced low CTC scores, although higher than CMF for nausea, vomiting, alopecia, constipation, stomatitis (P<0.001), infection (P=0.001) and fatigue (P=0.03). Supportive treatments required, however, were similar across randomised treatments. On-treatment deaths were more common with CMF (13) than ECMF(5). Optimal course-delivered dose intensity (CDDI > or =85%) was received more often by ECMF patients (83 vs 76%: P=0.0002), and was associated with better RFS (P=0.0006). QoL over 2 years was equivalent across treatments, despite minimally worse side effects for ECMF during treatment. ECMF benefit spanned all levels of toxicity, CDDI and QoL. There are no reported acute myeloid leukaemias or cardiac dysfunctions. ECMF is tolerable, deliverable, and significantly more effective than CMF, with no serious long-term toxicity or QoL detriment.

A 41-year-old female suffered from epigastralgia and intermittent constipation for 10 months, and abdominal fullness and intermittent pain for 6 months, before seeking help. Double contrast barium study of the colon showed multiple indentations on the sigmoid, ascending, and proximal transverse portions with tethered adjacent mucosal outline as well as the presence of ascites compatible with peritoneal carcinomatosis. Mediolateral oblique mammogram showed a speculated mass with some intratumoral microcalcifications in the upper retroareolar portion of the right breast. Due to the persistent abdominal complaints, laparotomy was done. Breast lump biopsy was done simultaneously. On opening abdominal cavity, massive yellowish ascites was noted. Diffuse small nodules over omentum and mesentery retraction were found. Bilateral ovarian masses were also noted. Right oophorectomy and omentectomy were performed. Histologic findings and results of immunohistochemical stains were consistent with diagnosis of primary breast cancer with metastasis to ovary and omentum.

Tendencies to suppress negative emotions have been shown to predict adjustment to cancer and cancer progression. We examined whether emotional suppression, in terms of both general and emotion-specific tendencies, predict symptom reports, mood states, and coping appraisals during adriamycin/doxorubicin, cyclophosphamide/cytoxan chemotherapy for breast cancer. Forty participants completed a measure yielding scores for anxiety suppression, anger suppression, depression suppression, and total emotional suppression. They then reported their experiences of 34 physical symptoms, mood, and coping efficacy on a daily basis for the duration of treatment (84 days). Mixed model analyses revealed that emotional suppression predicted lower reports of symptoms that are vague, well-known, and potentially embarrassing side effects of chemotherapy (e.g., fatigue and constipation). Emotional suppression and particularly anger suppression predicted higher reports of symptoms relating to immune function and cardiovascular arousal (e.g., mouth sores and heart palpitations) and with appraisals of poorer coping. The three suppression tendencies exhibited distinctive patterns of relationships with symptoms, mood, and coping appraisals, suggesting that anxiety suppression, anger suppression, and depression suppression have partially independent relationships with symptomatic and mood processes. The findings highlight the potential importance of emotional suppression for understanding symptom and coping responses during chemotherapy.
