Statin use and its effect on all-cause mortality of melanoma patients: a population-based Dutch cohort study

Preclinical data showed anticancer effects of statins in melanoma, but meta-analyses could not demonstrate a reduced melanoma incidence in statin users. Rather than preventing occurrence, statins might reduce growth and metastatic spread of melanoms and ultimately improve survival. In this population-based study, we investigated the relationship between statin use and survival of melanoma patients

Patterns of metachronous metastases after curative treatment of colorectal cancer

BACKGROUND: This study aimed to provide information on timing, anatomical location, and predictors for metachronous metastases of colorectal cancer based on a large consecutive series of non-selected patients. METHODS: All patients operated on withcurative intent for colorectal cancer (TanyNanyM0) between 2003 and 2008 in the Dutch Eindhoven Cancer Registry were included (N=5671)

Expression of HLA Class I Antigen, Aspirin Use, and Survival After a Diagnosis of Colon Cancer

IMPORTANCE Use of aspirin (which inhibits platelet function) after a colon cancer diagnosis is associated with improved overall survival. Identifying predictive biomarkers of this effect could individualize therapy and decrease toxic effects. OBJECIVE To demonstrate that survival benefit associated with low-dose aspirin use after a diagnosis of colorectal cancer might depend on HLA class I antigen expression

beta-Blocker use and all-cause mortality of melanoma patients: results from a population-based Dutch cohort study

BACKGROUND: Results from preclinical and observational studies suggest that beta-adrenoreceptor inhibition might influence disease progression of melanoma. PATIENTS AND METHODS: Patients 18years with cutaneous melanoma (Breslow thickness >1mm) regitered in the Eindhoven Cancer Registry between January 1, 1998 and December 31, 2010, who were also registered with PHARMO record linkage system (RLS), were eligible

Pulmonary embolism, myocardial infarction, and ischemic stroke in lung cancer patients: results from a longitudinal study

PURPOSE: In this cohort study, the rates of pulmonary embolism (PE), myocardial infarction (MI), and ischemic stroke (IS) before and after lung cancer (LC) diagnosis were compared to cancer-free controls. METHODS: Patients with LC during 2000-2007ere selected from PALGA, the Dutch Pathology Registry, and linked to the PHARMO medical record linkage system, including drug use and hospitalizations of 3 million inhabitants in the Netherlands

Major changes in chemotherapy regimens administered to breast cancer patients during 2000-2008 in the Netherlands

There is little information available on the patterns of chemotherapy regimens administered in daily practice to patients with early stage and metastatic or recurrent breast cancer. To determine the trends in type of chemotherapy regimens used in beast cancer patients, newly diagnosed breast cancer patients in the period 2000-2008 who received chemotherapy were identified from the Eindhoven Cancer Registry (ECR) and linked to the PHARMO RLS, including data on, e

Unjustified prescribing of CYP2D6 inhibiting SSRIs in women treated with tamoxifen

Tamoxifen is a largely inactive pro-drug, requiring metabolism into its most important metabolite endoxifen. Since the cytochrome P450 (CYP) 2D6 enzyme is primarily involved in this metabolism, genetic polymorphisms of this enzyme, but also drug-inuced CYP2D6 inhibition can result in considerably reduced endoxifen formation and as a consequence may affect the efficacy of tamoxifen treatment

Aspirin use after diagnosis improves survival in older adults with colon cancer: a retrospective cohort study

OBJECTIVES: To assess survival in relation to aspirin use after diagnosis in older adults with colon cancer. DESIGN: Subgroup analysis of a previously published cohort and retrospective study. SETTING: Individuals registered in the Eindhoven CancerRegistry (ECR) between 1998 and 2007, linked to prescriptions of low-dose aspirin (80 mg) registered in a community pharmacy database
