The use of onestep nucleic acid amplification (OSNA) and tumour related factors in the treatment of axillary breast cancer: A predictive model.

AIMS: We aimed to determine the effectiveness of CK19 mRNA copy number and tumour related factors in predicting non-sentinel axillary nodal involvement, in order to facilitate the formulation of local treatment guidelines for axillary clearance (ANC) following intra-operative analysis of the sentinel node biopsy (SNB) using one-step nucleic acid amplification (OSNA). METHODS: Patients due to have (SNB) at our institution for breast cancer as well as patients with high grade ductal carcinoma in situ with pre-operative negative assessment of the axilla were included. Alternate slices of each node were sent for assessment by either OSNA or histopathology. Immediate ANC was performed if OSNA was positive. The CK19 mRNA nodal copy number, the total tumour load (TTL) measured by summation of mRNA copy numbers of all positive nodes, the nodal status at ANC and tumour characteristics for each patient were recorded. A model of risk probability was constructed using TTL and tumour related factors. RESULTS: 664 nodes were analysed from 425 patients who had SNB performed between 2011 and 2014. ANC was performed on 105 of these patients. The concordance between OSNA and histology was 91.4% and negative predictive value (NPV) was 97%. TTL (p = 0.003) and LVI (p = 0.04) were identified as risk factors for non-sentinel nodal involvement. The risk probability model identified all patients with pN2 disease for ANC. CONCLUSION: In the future a decision to perform ANC will be based on a risk stratification model based on TTL and tumour related factors.

The impact of a breast cancer diagnosis on religious/spiritual beliefs and practices in the UK.

The use of religious/spiritual resources may increase when dealing with the stress of a cancer diagnosis. However, there has been very little research conducted into changes in religious/spiritual beliefs and practices as a result of a cancer diagnosis outside the USA. The aim of this study was to examine the impact of a breast cancer diagnosis on patients' religious/spiritual beliefs and practices in the UK where religious practice is different. The study used two methods. One compared the religious/spiritual beliefs and practices of 202 patients newly diagnosed with breast cancer with those of a control group of healthy women (n = 110). The other examined patients' perceived change in religious/spiritual beliefs and practices at the time of surgery with those in the year prior to surgery. The aspects of religiousness/spirituality assessed were: levels of religiosity/spirituality, strength of faith, belief in God as well as private and public practices. Patient's perceived their belief in God, strength of faith and private religious/spiritual practices to have significantly increased shortly after surgery compared with the year prior to surgery. However, there were no significant differences in religious/spiritual beliefs and practices between patients and healthy participants. Change scores demonstrated both a reduction and an increase in religious/spiritual beliefs and practices. Although belief in God, strength of faith and private religious/spiritual practices were perceived by patients to be significantly higher after their cancer diagnosis, no significant differences in religious/spiritual beliefs and practices were found between the cancer group at the time of surgery and the control group. Different methodologies appear to produce different results and may explain contradictions in past US studies. Limitations of this study are discussed and suggestions for future research are made.

Religious coping strategies in patients diagnosed with breast cancer in the UK.

OBJECTIVES: The use of religious/spiritual coping strategies may be particularly prevalent when dealing with the stress of a cancer diagnosis. There has, however, been very little research conducted on this topic outside the USA. Existing measures of coping largely ignore the complexity of religious/spiritual coping and its potential to be adaptive as well as maladaptive. The aim of this study was to examine the prevalence of various religious coping strategies in a UK cancer sample. METHOD: A longitudinal design assessed religious coping strategies in patients newly diagnosed with breast cancer at the time of surgery and at 3 and 12 months post surgery. We recruited 202 patients of which, at 12 months, 160 remained. A non-religious coping measure was included for comparison. RESULTS: The use of religious coping strategies was overall common; up to 73% of patients used positive religious coping to some degree at surgery and up to 53% experienced various religious/spiritual struggles. The use of some religious coping strategies showed differing patterns of change across time while others remained stable. CONCLUSION: Using religious/spiritual resources in the coping process during the early stages of breast cancer appears common in the UK. Patients may benefit from having their spiritual needs addressed as experiencing some form of religious/spiritual struggle may serve as a barrier to illness adjustment. Health-care professionals should also be aware that some religious coping strategies may be more prevalent at different times during the first year of illness.

Laser therapy for breast cancer: MR imaging and histopathologic correlation.

PURPOSE: To investigate magnetic resonance (MR) imaging guidance of interstitial laser photocoagulation to treat primary breast cancer. MATERIALS AND METHODS: Twenty female patients with symptomatic breast cancers diagnosed at cytologic examination underwent interstitial laser photocoagulation by means of a single fiber prior to surgical excision. Gadolinium-enhanced T1-weighted three-dimensional fast low-angle shot (FLASH) MR imaging was performed before and after laser therapy (median, 48 hours; range, 24-96 hours). Following resection, tumors were mapped in detail histopathologically. The extent of disease, size of laser burn, and extent of residual tumor were correlated with MR findings. RESULTS: Twenty-seven tumors were detected at histopathologic examination in the 20 patients. Five patients had more than one invasive mass. Twenty-five of the 27 tumors were identified as discrete enhancing masses at MR. The two missed invasive foci were obscured on MR images by diffuse patchy enhancement that correlated with the presence of an associated extensive intraductal component. Early (4-hour) follow-up images failed to depict the laser effect. Later (24-96 hours) follow-up images depicted the laser-induced necrosis as a zone of nonenhancement within the residual enhancing tumor. The correlation coefficients (MR vs histopathologic analysis) for the laser-burn diameter and residual tumor were 0.80 and 0.86, respectively. CONCLUSION: Delayed gadolinium-enhanced MR images can help define the extent of laser-induced necrosis and residual tumor after interstitial laser photocoagulation therapy in breast cancer.

Post irradiation sarcoma of soft tissue and bone.

Thirty-eight patients with sarcomas of soft tissue and bone which followed previous radiotherapy have been treated at the Royal Marsden Hospital between 1951 and 1992. The commonest reasons for initial radiotherapy were carcinoma of the breast and lymphoma, and the median time to development of sarcoma was 11 years. The only long term survivors were those who had complete surgical excision. Seven patients required forequarter amputation (30% of the extremity sarcomas) which reflects their frequent situation in the shoulder girdle and upper arm and the close proximity to the brachial plexus and vascular bundle. The overall prognosis was poor (5-year survival 30%) and probably reflects the poor prognostic factors (size, grade and tumour site) present at the time of diagnosis.

Naevoid basal cell carcinoma (Gorlin's) syndrome.

The multiple naevoid basal cell carcinoma syndrome (Gorlin's syndrome) is an inherited multisystem disorder which affects not only the skin, but also the skeletal system and a variety of other tissues and organs. This is a report of the case of a 29 year old woman who presented with multiple advanced basal cell carcinomas. On the basis of a literature review, guidelines for management are suggested and the importance of early diagnosis and regular follow-up is emphasized.

Long term venous access using a totally implantable drug delivery system in patients with cystic fibrosis and bronchiectasis.

A completely implantable, subcutaneous, venous access system (Port-a-Cath) has been used for antibiotic therapy in 26 patients with cystic fibrosis or bronchiectasis over a period of 45 months. During this period there were ten complications in eight patients and in four patients all or part of the system had to be replaced. Nevertheless, the actuarial median functional survival of the implanted system exceeded 30 months. The Port-a-Cath system provides longer periods of venous access and has a lower complication rate than conventional, percutaneous central venous lines.

Factors influencing survival following fractures of the upper end of the femur.

Patients undergoing treatment for fractures of the upper end of the femur in a district general hospital over a 2-year period were analysed to identify preoperative illness, operative factors or postoperative complications associated with increased mortality. Both the mean age and mortality rate were higher than in many other reported series. The elderly diabetic was identified as a particularly high-risk patient. Dislocation following hemiarthroplasty was associated with advanced age and carried a formidable mortality.

Angiosarcoma arising in a patient with Maffucci syndrome.

Maffucci syndrome comprises multiple enchondromas together with cutaneous haemangiomas. Review of the literature shows a 15-20% incidence of sarcomatous change in one or more of the enchondromas. Malignancy arising from the vascular component, however, has only been reported in one case. We present a further case where a patient with Maffucci syndrome presented with multifocal angiosarcoma.

Long-term venous access using a subcutaneous implantable drug delivery system.

To facilitate long-term venous access in patients receiving chemotherapy, a subcutaneous totally implantable system (Port-a-Cath, Phamacia) has been used in 14 patients. The method of implantation and the advantages over conventional central venous catheters are discussed. The expense of the system necessitates careful patient selection.

Self-inflicted burns: a 5-year retrospective study.

Forty-two patients who had attempted suicide by burning were admitted to the North West Thames Regional Burns Unit over a 5-year period. Over three-quarters of these patients had previous psychiatric illness and a quarter had previously attempted suicide. In no case was political or religious protest a motive. The number of non-Caucasians was higher than expected from population statistics and fatal burns were more common in this group. The mean age was 36 years and the overall mortality rate was 48 per cent. The mortality was not significantly higher than for accidental burns of comparable severity.
