BACKGROUND The inhibition of poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) is a potential synthetic lethal therapeutic strategy for the treatment of cancers with specific DNA-repair defects, including those arising in carriers of a BRCA1 or BRCA2 mutation. We conducted a clinical evaluation in humans of olaparib (AZD2281), a novel, potent,(More)
Lymphatic vessels are essential for the removal of interstitial fluid and prevention of tissue edema. Lymphatic capillaries lack associated mural cells, and collecting lymphatic vessels have valves, which prevent lymph backflow. In lymphedema-distichiasis (LD), lymphatic vessel function fails because of mutations affecting the forkhead transcription factor(More)
INTRODUCTION Lymphoedema-distichiasis syndrome (LD) (OMIM 153400) is a rare, primary lymphoedema of pubertal onset, associated with distichiasis. Causative mutations have now been described in FOXC2, a forkhead transcription factor gene. Numerous clinical associations have been reported with this condition, including congenital heart disease, ptosis,(More)
PURPOSE To evaluate tumor response, pharmacodynamic effects, and safety of a combination of lomeguatrib (LM), an O6-methylguanine DNA-methyltransferase (MGMT) inactivator, and temozolomide (TMZ), TMZ alone, and LM/TMZ after disease progression on TMZ alone in patients with advanced melanoma. PATIENTS AND METHODS Patients with unresectable stage III or IV(More)
Hidradenitis suppurativa (HS) is a chronic disease manifested by recurrent abscesses, sinus tracts and scarring. It arises most commonly, however, not exclusive from apocrine gland bearing skin. This review article sets out to clarify the importance of early diagnosis, the pathogenesis and aetiology of HS, and evidence for medical and surgical therapies for(More)
Axillary surgery for breast cancer may be followed, months to years later, by chronic arm lymphedema. A simple 'stopcock' mechanism (reduced lymph drainage from the entire limb through surviving lymphatics) does not explain many clinical aspects, including the delayed onset and selective sparing of some regions, e.g., hand. Quantitative lymphoscintigraphy(More)
Primary congenital lymphoedema (Milroy disease) is a rare autosomal dominant condition for which a major causative gene defect has recently been determined. Mutations in the vascular endothelial growth factor receptor 3 (VEGFR-3) gene have now been described in 13 families world-wide. This is a review of the condition based on the clinical findings in 71(More)
This paper describes a randomized controlled crossover study examining the effects of manual lymphatic drainage (MLD) in 31 women with breast cancer-related lymphoedema. MLD is a type of massage used in combination with skin care, support/compression therapy and exercise in the management of lymphoedema. A modified version of MLD, referred to as simple(More)
BACKGROUND The psychological morbidity, functional impairment, and disturbance in psychosocial adjustment to illness was evaluated in relation to breast cancer-related arm swelling. METHODS Fifty women with breast cancer-related arm swelling were matched with 50 control subjects for age, duration since treatment, and type of treatment received. All study(More)
We report an allelic series of eight mutations in GATA2 underlying Emberger syndrome, an autosomal dominant primary lymphedema associated with a predisposition to acute myeloid leukemia. GATA2 is a transcription factor that plays an essential role in gene regulation during vascular development and hematopoietic differentiation. Our findings indicate that(More)
