Bacterial colonization of seromas after breast cancer surgery with and without local steroid prophylaxis.

Background: Seroma formation is a frequent postoperative sequela after mastectomy for primary breast cancer. We investigated the role of bacterial colonization of seroma fluid with three different culture methods and the effect of intracavitary steroids.

Methods: The study group consisted of 212 patients scheduled for mastectomy from a previously performed double-blind randomized placebo-controlled intervention trial.

Pressure pain sensitivity as a marker for stress and pressure pain sensitivity-guided stress management in women with primary breast cancer.

Objectives: To validate (1) Pressure Pain Sensitivity (PPS) as a marker for stress and (2) a PPS-guided intervention in women with primary Breast Cancer (BC).

Methods: (1) A total of 58 women with BC were examined before and after 6 months of intervention. A control group of 165 women office employees was divided in a High Stress Group (HSG, n = 37) and a Low Stress Group (LSG, n = 128) to evaluate the association between PPS, questionnaire-related Quality of Life (QOL) and self-evaluated stress.

Local injection of methylprednisolonacetat to prevent seroma formation after mastectomy.

Introduction: This study served the following three purposes: To evaluate the prophylactic effect against seroma of a single dose of steroid in the mastectomy cavity, to evaluate the thesis that there is a connection between subclinical bacterial colonization and seroma formation and to evaluate if a simple urine stix test can detect postmastectomy infection.

Material And Methods: This was a double-blinded and randomized study of injection of methylprednisolonacetate versus saline in the mastectomy cavity at the time of drain removal. A total of 160 females were enrolled after mastectomy.

No effect of steroids on seroma formation after mastectomy.

Introduction: Seroma formation is a common problem after breast surgery. Studies indicate that seroma formation is a result of the postoperative inflammatory process. Glucocorticoid inhibits the inflammatory response.

Intraoperative immunohistochemistry staining of sentinel nodes in breast cancer: clinical and economical implications.

The study aimed to evaluate intraoperative immunohistochemistry (IHC) staining of sentinel nodes in primary breast cancer surgery. We analysed retrospectively 1209 consecutive sentinel node procedures and compared the rate of late positive metastases in sentinel node biopsy (SNB) and the duration of the surgical procedures before (n=706) and after (n=503) introducing intraoperative IHC on frozen section. We also did a cost analysis.

Heterogeneity of breast cancer associations with five susceptibility loci by clinical and pathological characteristics.

A three-stage genome-wide association study recently identified single nucleotide polymorphisms (SNPs) in five loci (fibroblast growth receptor 2 (FGFR2), trinucleotide repeat containing 9 (TNRC9), mitogen-activated protein kinase 3 K1 (MAP3K1), 8q24, and lymphocyte-specific protein 1 (LSP1)) associated with breast cancer risk. We investigated whether the associations between these SNPs and breast cancer risk varied by clinically important tumor characteristics in up to 23,039 invasive breast cancer cases and 26,273 controls from 20 studies. We also evaluated their influence on overall survival in 13,527 cases from 13 studies.

Genome-wide association study identifies novel breast cancer susceptibility loci.

Breast cancer exhibits familial aggregation, consistent with variation in genetic susceptibility to the disease. Known susceptibility genes account for less than 25% of the familial risk of breast cancer, and the residual genetic variance is likely to be due to variants conferring more moderate risks. To identify further susceptibility alleles, we conducted a two-stage genome-wide association study in 4,398 breast cancer cases and 4,316 controls, followed by a third stage in which 30 single nucleotide polymorphisms (SNPs) were tested for confirmation in 21,860 cases and 22,578 controls from 22 studies.

Estrogen receptor alpha polymorphism and risk of cardiovascular disease, cancer, and hip fracture: cross-sectional, cohort, and case-control studies and a meta-analysis.

Background: We hypothesized that the estrogen receptor alpha (ESR1) IVS1-397T/C polymorphism affects high-density lipoprotein cholesterol response to hormone replacement therapy and risk of cardiovascular disease (CVD), cancer of reproductive organs, and hip fracture.

Methods And Results: We studied cross-sectionally 9244 individuals from the Danish general population and followed them up for 23 to 25 years. End points were CVD (ischemic heart disease, myocardial infarction, angina pectoris, ischemic cerebrovascular disease, ischemic stroke, other ischemic cerebrovascular disease, venous thromboembolism, deep vein thrombosis, and pulmonary embolism), cancer of reproductive organs (breasts, ovaries, uterus, and prostate), and hip fracture.

A common coding variant in CASP8 is associated with breast cancer risk.

The Breast Cancer Association Consortium (BCAC) has been established to conduct combined case-control analyses with augmented statistical power to try to confirm putative genetic associations with breast cancer. We genotyped nine SNPs for which there was some prior evidence of an association with breast cancer: CASP8 D302H (rs1045485), IGFBP3 -202 C --> A (rs2854744), SOD2 V16A (rs1799725), TGFB1 L10P (rs1982073), ATM S49C (rs1800054), ADH1B 3' UTR A --> G (rs1042026), CDKN1A S31R (rs1801270), ICAM5 V301I (rs1056538) and NUMA1 A794G (rs3750913). We included data from 9-15 studies, comprising 11,391-18,290 cases and 14,753-22,670 controls.

Increased risk of breast cancer associated with CHEK2*1100delC.

Purpose: CHEK2*1100delC heterozygosity has been associated with increased risk of breast, prostate, and colorectal cancer in case-control studies. We tested the hypothesis that CHEK2*1100delC heterozygosity in the general population increases the risk of cancer in general, and breast, prostate, and colorectal cancer in particular.

Patients And Methods: We performed a prospective study of 9,231 individuals from the Danish general population, who were observed for 34 years, and we performed a case-control study including 1,101 cases of breast cancer and 4,665 controls.

[Patients' experiences--indications for treatment quality in breast cancer surgery].

Introduction: After the establishment of a centralised unit for the surgical treatment of breast cancer in the county of Copenhagen, Denmark, a number of parameters concerning the quality of patients' in-hospital stay were established. A survey of patients' experiences was done via a questionnaire in which they described their satisfaction level.

Materials And Methods: Two questionnaires including 43 questions were sent to 400 women recently operated on for primary breast cancer.

[Treatment of breast abscess. An analysis of patient material and implementation of recommendations].

Introduction: Several options for treatment of abscesses in the breast have appeared during the last two decades. No randomised studies comparing these options have been performed.

Material And Methods: A retrospective study of the treatment of breast abscesses over a four-year-period.
