Poor Prognosis After Second Locoregional Recurrences in the CALOR Trial.

Background: Isolated locoregional recurrences (ILRRs) of breast cancer confer a significant risk for the development of distant metastasis. Management practices and second ILRR events in the Chemotherapy as Adjuvant for LOcally Recurrent breast cancer (CALOR) trial were investigated.

Methods: In this study, 162 patients with ILRR were randomly assigned to receive postoperative chemotherapy or no chemotherapy.

Results of 20- versus 45-min post-infusion scalp cooling time in the prevention of docetaxel-induced alopecia.

Purpose: For patients, chemotherapy-induced alopecia (CIA) is one of the most distressing side effects of treatment. Scalp cooling can prevent or minimise CIA; the results may depend on the duration of cooling. Since a previous study on post-infusion cooling time in patients treated with docetaxel chemotherapy found no difference between 90 and 45 min, we investigated whether hair-preserving results could be maintained with a shorter post-infusion cooling time.

The effects of short-term fasting on tolerance to (neo) adjuvant chemotherapy in HER2-negative breast cancer patients: a randomized pilot study.

Background: Preclinical evidence shows that short-term fasting (STF) protects healthy cells against side effects of chemotherapy and makes cancer cells more vulnerable to it. This pilot study examines the feasibility of STF and its effects on tolerance of chemotherapy in a homogeneous patient group with early breast cancer (BC).

Methods: Eligible patients had HER2-negative, stage II/III BC.

Stick Together: A Nordic Walking Group Intervention for Breast Cancer Survivors.

Axillary lymph node dissection and axillary radiation as part of breast cancer treatment often result in arm and shoulder morbidity and limitations in daily functioning. Over and above the general benefits for cardiorespiratory fitness, Nordic Walking particularly targets at the muscles of the upper extremities and shoulder. This may increase shoulder range of motion and lead to a reduction in functional limitations.

Improved Circulating Tumor Cell Detection by a Combined EpCAM and MCAM CellSearch Enrichment Approach in Patients with Breast Cancer Undergoing Neoadjuvant Chemotherapy.

Circulating tumor cells (CTC) are detected by the CellSearch System in 20% to 25% of patients with primary breast cancer (pBC). To improve CTC detection, we investigated melanoma cell adhesion molecule (MCAM) as enrichment marker next to epithelial cell adhesion molecule (EpCAM) and tested the clinical relevance of MCAM-positive CTCs in patients with HER2-negative stage II/III pBC starting neoadjuvant chemotherapy (NAC) in the NEOZOTAC trial. Using the CellSearch System, EpCAM-positive and MCAM-positive CTCs were separately enriched from 7.

The prognostic relevance of the mitotic activity index in axillary lymph node-negative breast cancer.

The aim of the present study is to look at the mitotic activity index (MAI) as a prognostic factor in a prospective population-based cohort of lymph node-negative invasive breast cancer patients. Analyses were based on 2,048 breast-conserving therapies in 1,971 patients, node-negative, and without any form of adjuvant systemic therapy with long-term follow-up. The 15-year distant metastases-free survival (DMFS) for women ≤55 years was 88.

Minimal impact of adjuvant exemestane or tamoxifen treatment on mammographic breast density in postmenopausal breast cancer patients: a Dutch TEAM trial analysis.

Background: Mammographic breast density is one of the strongest independent risk factors for developing breast cancer. We examined the effect of exemestane and tamoxifen on breast density in Dutch postmenopausal early breast cancer patients participating in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial.

Material And Methods: Analogue mammograms of selected TEAM participants before start, and after one and two (and if available after three) years of adjuvant endocrine therapy were collected centrally and reviewed.

Guidelines-based diagnostic process does increase hospital delay in a cohort of colorectal cancer patients: a population-based study.

This is an investigation of factors determining hospital delay until treatment in an unrestricted population of colorectal cancer patients in the western part of the Netherlands. All patients with newly diagnosed colon (n=2146) and rectal carcinoma (n=1036) in the period 2006-2008 were included in analyses of inhospital delay (first hospital visit until first treatment >35 days). One-third of all patients were also available for analyses of prehospital delay (enrollment until first hospital visit >7 days).

Endocrine therapy for breast cancer: assessing an array of women's treatment experiences and perceptions, their perceived self-efficacy and nonadherence.

Background: Although adjuvant endocrine therapy effectively prevents breast cancer recurrence, nonadherence rates are substantial. We therefore examined associations of women's experiences and perceptions regarding the efficacy, side effects, and practical problems of endocrine therapy with nonadherence. Furthermore, we examined whether women's perceived self-efficacy moderated these associations.

Efficacy of six month neoadjuvant endocrine therapy in postmenopausal, hormone receptor-positive breast cancer patients--a phase II trial.

Background: Neoadjuvant hormonal therapy (NHT) is playing an increasing role in the clinical management of breast cancer (BC) and may improve surgical outcomes for postmenopausal, oestrogen receptor (ER)-positive BC patients. However, there is currently no consensus on the optimal duration of NHT before surgery. Here, we present the outcomes of the TEAM IIA trial, a multicentre, phase II trial investigating the efficacy of six months of neoadjuvant exemestane in postmenopausal, strong ER-positive (ER+, ⩾50%) BC patients.

Prognostic significance of geriatric assessment in combination with laboratory parameters in elderly patients with aggressive non-Hodgkin lymphoma.

The age-adjusted International Prognostic Index (IPI) is an important prognostic factor for patients with non-Hodgkin lymphoma (NHL). We investigated whether a geriatric assessment (GA) is of additional prognostic value in NHL. In this prospective cohort study of 44 patients aged 70 years or older with NHL receiving rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), a GA was administered before the start of chemotherapy.

External validity of a trial comprised of elderly patients with hormone receptor-positive breast cancer.

Background: Inclusion in trials is selective, and thus results may not be generalizable to the general population. The aim of this study was to investigate the external validity of randomized clinical trial outcomes for elderly breast cancer patients.

Methods: We compared characteristics and outcomes of breast cancer patients (n = 1325) who participated in a randomized clinical trial (Tamoxifen Exemestane Adjuvant Multinational trial) with unselected breast cancer patients of corresponding age from the general population (n = 1056).

Germline variants in the CYP19A1 gene are related to specific adverse events in aromatase inhibitor users: a substudy of Dutch patients in the TEAM trial.

Musculoskeletal adverse events (MSAEs) and vasomotor symptoms (VMSs) are known side-effects of aromatase inhibitors, and may be related to genetic variations of the aromatase gene (CYP19A1). We investigated the relationship between these specific AEs and single nucleotide polymorphisms (SNPs) in the CYP19A1 gene in postmenopausal, hormone receptor-positive early breast cancer (BC) patients treated with adjuvant exemestane for 5 years. Dutch patients who were randomized to receive 5 years of exemestane in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial were included.

Chemotherapy for isolated locoregional recurrence of breast cancer (CALOR): a randomised trial.

Background: Patients with isolated locoregional recurrences (ILRR) of breast cancer have a high risk of distant metastasis and death from breast cancer. We aimed to establish whether adjuvant chemotherapy improves the outcome of such patients.

Methods: The CALOR trial was a pragmatic, open-label, randomised trial that accrued patients with histologically proven and completely excised ILRR after unilateral breast cancer who had undergone a mastectomy or lumpectomy with clear surgical margins.

CYP2D6 genotype in relation to hot flashes as tamoxifen side effect in a Dutch cohort of the tamoxifen exemestane adjuvant multinational (TEAM) trial.

In tamoxifen-treated breast cancer patients the occurrence of hot flashes may be associated with effective estrogen receptor antagonism dependent on genetic variations of metabolic enzymes and the estrogen receptor. Early breast cancer patients who were randomized to receive tamoxifen, followed by exemestane within the tamoxifen exemestane adjuvant multinational trial were genotyped for five CYP2D6 alleles. CYP2D6 genotypes and phenotypes were related to the occurrence of hot flashes as adverse event during the first year of tamoxifen use (primary aim) and the time to the occurrence of hot flashes as AE during the complete time on tamoxifen (secondary aim).

Frailty and malnutrition predictive of mortality risk in older patients with advanced colorectal cancer receiving chemotherapy.

Introduction: In general, geriatric assessment (GA) provides the combined information on comorbidity and functional, nutritional and psychosocial status and may be predictive for mortality outcome of cancer patients. The impact of geriatric assessment on the outcome of older patients with colorectal cancer treated with chemotherapy is largely unknown.

Methods: In a prospective study, 143 patients with colorectal cancer who were 70years and older were assessed before chemotherapy by Mini Nutritional Assessment (MNA), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Groningen Frailty Indicator (GFI) and Mini Mental State Examination (MMSE).

Cost-effectiveness analysis of scalp cooling to reduce chemotherapy-induced alopecia.

Background: Alopecia is a frequently occurring side effect of chemotherapy that often can be prevented by cooling the scalp during the infusion. This study compared effects and costs of scalp cooling with usual general oncological care, i.e.

Oncologists' practice and attitudes regarding fertility preservation in female cancer patients: a pilot study in the Netherlands.

Purpose: The aim of this study was to assess oncologists' practice and attitudes regarding treatment-related infertility and fertility preservation in female cancer patients of reproductive age.

Participants And Methods: Recruitment letters with a 7-item questionnaire were sent to 454 oncologists.

Results: Two hundred and six of the 454 physicians (45%) responded and 96 questionnaires were used for analysis.

Factors influencing the effectiveness of scalp cooling in the prevention of chemotherapy-induced alopecia.

The success of scalp cooling in preventing or reducing chemotherapy-induced alopecia (CIA) is highly variable between patients and chemotherapy regimens. The outcome of hair preservation is often unpredictable and depends on various factors. Methods.

Specific adverse events predict survival benefit in patients treated with tamoxifen or aromatase inhibitors: an international tamoxifen exemestane adjuvant multinational trial analysis.

Purpose: Specific adverse events (AEs) associated with endocrine therapy and related to depletion or blocking of circulating estrogens may be related to treatment efficacy. We investigated the relationship between survival outcomes and specific AEs including vasomotor symptoms (VMSs), musculoskeletal adverse events (MSAEs), and vulvovaginal symptoms (VVSs) in postmenopausal patients with breast cancer participating in the international Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial.

Patients And Methods: Primary efficacy end points were disease-free survival (DFS), overall survival (OS), and distant metastases (DM).

Translation and linguistic validation of the FACT-EGFRI-18 quality of life instrument from English into Dutch.

Purpose: The Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitor 18 (FACT-EGFRI-18) is a patient-reported outcomes questionnaire developed to assess the effect of EGFRI on patients. The FACT-EGFR-18 was translated into Dutch and evaluated in order to document that the translation adequately captures the concepts of the original English-language version of the questionnaire and is readily understood by subjects in the target population.

Method: Translation of the FACT-EGFRI-18 from English to Dutch was accomplished by employing the Functional Assessment of Chronic Illness Therapy (FACIT) multilingual translation methodology.

Chemotherapy alters monocyte differentiation to favor generation of cancer-supporting M2 macrophages in the tumor microenvironment.

Current therapy of gynecologic malignancies consists of platinum-containing chemotherapy. Resistance to therapy is associated with increased levels of interleukin (IL)-6 and prostaglandin E2 (PGE(2)), 2 inflammatory mediators known to skew differentiation of monocytes to tumor-promoting M2 macrophages. We investigated the impact of cisplatin and carboplatin on 10 different cervical and ovarian cancer cell lines as well as on the ability of the tumor cells to affect the differentiation and function of cocultured monocytes in vitro.

Experiences with the FACT-EGFRI-18 instrument in EGFRI-associated mucocutaneous adverse events.

Purpose: The functional assessment of cancer therapy epidermal growth factor receptor inhibitor 18 (FACT-EGFRI-18) is a patient-reported outcomes questionnaire developed to assess the effect of EGFRI on health-related quality of life (HRQoL).

Methods: Ten native-speaking residents of The Netherlands who reported EGFRI-associated mucocutaneous adverse events (mcAEs) were administered the questionnaire. Patients were subsequently asked a standardized series of questions about the items' personal relevance.

From despair to hope: a longitudinal study of illness perceptions and coping in a psycho-educational group intervention for women with breast cancer.

Objectives: This study examined the cross-sectional and longitudinal relationships of illness perceptions, coping, and distress in women with breast cancer. Illness perceptions and coping at baseline and changes in these variables over time served as possible predictors of distress at two follow-up points.

Design And Methods: Fifty-seven women with breast cancer who participated in a psychosocial aftercare programme completed a questionnaire before the start of the intervention, directly after the end of the intervention, and 1 year after the start of the intervention.

Influence of semi-quantitative oestrogen receptor expression on adjuvant endocrine therapy efficacy in ductal and lobular breast cancer - a TEAM study analysis.

Background: Multiple studies suggest better efficacy of chemotherapy in invasive ductal breast carcinomas (IDC) than invasive lobular breast carcinomas (ILC). However, data on efficacy of adjuvant endocrine therapy regimens and histological subtypes are sparse. This study assessed endocrine therapy efficacy in IDC and ILC.
