ABSTRACT

This study was performed to examine the association of cardiovascular risk factors with calcification in the coronary arteries, aortic arch and carotid arteries, assessed by multislice computed tomography (MSCT). This study was embedded in the Rotterdam Study, a population-based study in subjects aged 55 years and over. From October 2003 until December 2004, subjects were invited to undergo a MSCT scan. Coronary, aortic arch and carotid calcification were quantified according to the Agatston score. Analyses were performed in the first 1003 subjects. Age and current smoking were the strongest independent risk factors for arterial calcification. The odds ratio (OR) for age in women, irrespective of the vessel bed, was 1.1 (P<0.001) and in men it was 1.2 with aortic arch and 1.1 with carotid calcification (both P<0.001). Current smoking was associated with aortic arch calcification with an OR of 3.5 in women and of 4.7 in men (both P<0.001); and with carotid calcification with an OR of 2.1 in women (P<0.05) and of 4.1 in men (P<0.01). Hypertension, hypercholesterolemia and diabetes were also independently related to calcification, although not consistent across all vessel beds and for men and women. Obesity tended to be inversely related to arterial calcification in women, whereas low high-density lipoprotein-cholesterol showed no relation with arterial calcification. In conclusion, although associations were not completely consistent across the different vessel beds and for men and women, our results indicate that generally the same risk factors are present for atherosclerosis in the coronary, aortic arch and carotid circulation.

ABSTRACT

Breast cancer and cartilaginous tumours (enchondroma and chondrosaroma) were found to occur rather frequently in the same patient. In order to identify a possible association between occurrence of these tumour types, a population-based study was performed. This was a nation-wide case-control study, using the Dutch national pathology database. Between 1973 and 1998, the study identified 2295 cases of cartilaginous tumours in female patients and 132 636 females with breast cancer. Of these patients, 61 were diagnosed with both tumour types. To exclude a possible bias due to screening for occult bone metastases in breast cancer patients, a similar analysis was performed for lung cancer, since screening is performed similarly in lung cancer patients. Of 16 559 females diagnosed with lung cancer, only one case with a cartilaginous tumour was found. The odds ratio for a potential association of breast and cartilaginous tumours is 7.62, implicating a 7.62 increased risk for the same female patient having both breast cancer and a cartilaginous tumour. Furthermore, the mean age of onset in patients with breast cancer as the first tumour is nearly 10 years earlier than breast cancer in general, i.e. 51 years versus 60.9 years. The association of breast cancer and cartilaginous tumours and the early age of onset of breast cancer in these patients may suggest a genetic trait.

ABSTRACT

BACKGROUND: Children developing an isolated central nervous system (CNS) relapse as first recurrence of their acute lymphoblastic leukemia (ALL) are considered to have a systemic relapse as well. They are mostly treated with intensive chemotherapy and craniospinal irradiation. In most treatment schedules, irradiation is given early after induction treatment. Because craniospinal irradiation affects a large portion of hematopoietic bone marrow systemically, treatment is often delayed owing to aplasias. Also, dose reductions are frequently needed. Children receiving simultaneously irradiation and chemotherapy are prone to (often severe) neurotoxicity. This study reports on children with a first isolated CNS relapse of their ALL receiving chemotherapy for 40 weeks. Treatment ends with the administration of irradiation given after cessation of chemotherapy. PROCEDURE: Fourteen children, with blasts and >5 cells/mm(3) in two consecutive samples of cerebrospinal fluid and a blast percentage <5% in their bone marrow were treated according to an intensive systemic and site-specific chemotherapy. Craniospinal irradiation was administered after cessation chemotherapy. RESULTS: Event-free-survival was 57% (confidence interval 35-89%), freedom from relapse was 61.5%; follow-up ranges from 2.0 to 15.1 years (median 11.7 years). One child died from septicemia during induction. Five children experienced a second relapse and died from their malignancy. Two children [with a t(9;22) or a rearranged MLL gene] relapsed prior to radiotherapy. Outcome was related to duration of first remission, age at relapse, and identification as a high-risk patient at initial diagnosis. No neurologic complications were noted during and after treatment. CONCLUSIONS: Delayed irradiation for isolated CNS relapse in children with ALL gives favorable survival rates, without significant toxicity. Neurotoxicity was absent.
