Are surgeons effective counsellors for women with a family history of breast cancer?

AIM: In the TRACE (Trial of Genetic Assessment in Breast Cancer) study, the data on the time spent by the surgeon with the women with a family history of breast cancer was analysed with respect to the changes in the anxiety scores and breast cancer worry scores. We wanted to see whether longer consultation times with surgeons improved these scores. METHODS: In the TRACE study, women with a family history of breast cancer attended a standard breast clinic to be seen by a surgeon and nurse specialist. Anxiety scores and breast cancer worry scores of these women were recorded prior to attending the clinic and immediately after their appointment. RESULTS: In the 274 evaluable women, there was a significant improvement in the anxiety and breast cancer worries after surgical consultation but it did not correlate with the length of surgical consultation. However, women in the high-risk group showed a significant reduction of breast cancer worry score with longer consultation (P=0.032). CONCLUSIONS: Spending more time with the women with a family history of breast cancer does not help to reduce anxiety scores and breast cancer worry scores except in the subset of women who were told that their risk of breast cancer was high.

Obesity predisposes to increased drainage following axillary node clearance: a prospective audit.

BACKGROUND: Whilst sentinel node biopsy is being evaluated for optimising treatment of the axilla, axillary dissection remains the gold standard. Seroma formation, a common sequel to axillary dissection, has been shown to be associated with an increased incidence of wound infection, delayed healing, and lymphoedema. This study was conducted to evaluate the possible contributory role of obesity in axillary drainage following lymphatic dissection. PATIENTS AND METHODS: This study comprised a prospective review of all patients undergoing axillary dissection in conjunction with mastectomy or wide local excision. The total in-patient axillary drainage and the average daily drainage was correlated with various clinical parameters, including obesity, type of surgery, level of axillary dissection and nodal involvement. The body mass index (BMI) was used as a measure of obesity. RESULTS: During a 6-month period, axillary dissection was performed in 79 women. Nineteen patients were excluded. Patey mastectomy was performed on 33 (55%) and the remaining had breast conservation. The amount or duration of axillary drainage did not correlate with the type of operation, tumour histology, level of axillary dissection or the nodal status. Higher BMI correlated with increased mean daily axillary drainage and total volume drained, whilst in hospital. (Spearman correlation coefficient 0.42; P < 0.01). CONCLUSION: Obesity predisposes to increased axillary drainage following nodal clearance.

Portfolio learning with cancer patients: an integrated module in undergraduate medical education.

A model of undergraduate education based on a one to one relationship between a student and a patient with cancer has become a core module within the University of Wales College of Medicine undergraduate curriculum. The project combines the powerful impact of a one to one interaction with an active investigative and reflective approach to issues triggered from that patient's cancer journey. The aim is to provide each medical student with an understanding of the impact of a malignant disease and its treatment on patients and their families through the experience of one patient with cancer. The benefits of the project cover the areas of attitudes, skills and knowledge. Students are assessed on their involvement with the patient, in tutorials and on their portfolio, in which they record all aspects of the project. Student evaluations indicate high levels of appreciation of the project, despite its potentially strong emotional content.

Mastectomy follow-up by biennial mammograms: is it worthwhile?

The value of follow-up after mastectomy for breast cancer is controversial. One reason is to detect metachronous tumour in the contralateral breast, but the optimum method for achieving this is undecided. The long-term follow-up policy of our unit is annual clinical review combined with biennial mammography. We have assessed the benefit of this policy in the detection of tumours of the contralateral breast. The case notes of 216 patients undergoing mastectomy between 1978 and 1985, under the care of one consultant surgeon (DJTW) were reviewed. Follow-up was complete to December 1997, thus allowing a minimum follow-up of 12 years. The development of a metachronous tumour was recorded as was its method of detection : either clinically, by the patient or the clinician, or by routine mammography. Two-hundred and five patients were available for follow-up of the contralateral breast. Seventeen (8.3%) developed metachronous tumours. Eight were detected by the patient, 4 by the clinician and 5 by routine follow-up mammography. Biennial mammography does not appear to be beneficial in breast cancer follow-up. More work is required to determine the benefits of more frequent mammography, with or without breast self-examination and clinical review within the hospital environment or within primary care.

Chronic haematoma as a late complication of cosmetic breast augmentation.

To our knowledge, a chronic expanding haematoma has not been reported in a patient who received silicone gel breast prostheses for augmentation and never before at an interval as long as 12 years, as in our case. There have been occasional reports of chronic haematoma as complication of implantation of silicone breast prostheses after mastectomy for cancer, presenting 2.5-8 years later.

The National Breast Referral Guidelines have cut down inappropriate referrals in the under 50s.

AIMS: When the National Breast Referral Guidelines were applied to our local GPs letters immediately prior to their release in January 1996, it was shown that on the basis of the GPs own conclusions that 29% of symptomatic women could have been managed initially by their own GP without missing any carcinomas. We conducted this study at the Rapid Access Breast Clinic at the University Hospital of Wales to determine if the breast referral practices of local GPs have altered due to the breast referral guidelines. METHODS: We studied 2332 referrals from the inception of the Rapid Access Clinic in May 1995 to the issue of the guidelines, and 2421 referrals from May 1996 to the end of the year. Random samples of 600 patients were drawn from each year and the referral letters were scored as within or outside the guidelines. Family history patients were excluded. RESULTS: There was an 11% fall in referrals outside the guidelines in the under 50s (chi-squared=<0.001) but the 7% fall in the over 50s was not significant. CONCLUSIONS: The Breast Referral Guidelines seem to have been effective in reducing the higher level of inappropriate referrals in younger patients at less risk of carcinoma.

Psychological distress associated with waiting for results of diagnostic investigations for breast disease.

This paper presents the results of a multi-method research project investigating the psychological distress associated with waiting for results of diagnostic investigations in a delayed-results breast clinic. A cohort of 126 women completed standardized psychometric instruments to assess anxiety, mood and coping over 3 days. Semi-structured interviews were conducted with 20 respondents. The findings indicate that waiting sustained but did not exacerbate psychological distress. Peri-diagnostic anxiety, depression, uncertainty and confusion were associated with anxiety levels immediately following triple assessment. Women leaving the clinic with low anxiety retained this composure throughout the peri-diagnostic period. Those in the moderate and high anxiety groups recorded sustained anxiety, depression, uncertainty and confusion, with mean scores comparable to and exceeding those reported by psychiatric out-patients. Coping during the waiting period was typically accomplished by emotion-focused strategies. Qualitative data suggested the delayed-results clinic structure may facilitate psychological preparation for test results.

A randomized controlled study of portfolio learning in undergraduate cancer education.

Portfolio learning has not previously been reported for clinical undergraduate teaching. This open randomized study aimed to assess the effect of portfolio learning in the teaching of oncology to medical students. The project aimed to provide the student with a holistic understanding of the impact of the disease and its treatment on the patient and family, and the natural history of malignant disease, through long-term personal experience of a cancer patient. All undergraduate medical students entering Clinical Studies in October 1992 at the University of Wales College of Medicine were randomized to a study or control group. Both groups continued with the standard curriculum. Each study-group student followed a patient with cancer for 9 months, supported by bi-monthly small-group tutorials. Tutors were either general practitioners or hospital consultants, not necessarily oncologists; each was supplied with a tutor's resource pack of key oncology review papers. Students recorded triggers to learning and key items in a personal learning portfolio. Students' performances in clinical examinations and the contents of their portfolio was assessed. Final assessment was by hidden questions in the objective structured clinical examination (OSCE) in the final degree examination, when students in the study group showed higher marks in factual knowledge of oncology, particularly amongst the weaker students (P = 0.01). Those submitting portfolios for formative assessment had higher overall marks than those in the study group who did not (P = 0.04), representing the more motivated students. The whole study group showed a beneficial trend in their knowledge of oncology.

Power Doppler in breast tumours: a comparison with conventional colour Doppler imaging.

OBJECTIVE: Tumour vascularity can be assessed in-vivo using Doppler ultrasound. The purpose of this study was to determine whether Power Doppler imaging (PDI) better differentiates benign from malignant breast masses than conventional colour doppler imaging (CDI) on the basis of assessment of tumour vascularity. METHODS: One-hundred women with solid breast lumps (51 malignant lesions, 49 benign lesions) were investigated using a Toshiba SSA-270A ultrasound machine with a 5.0 MHz (3.75 MHz Doppler reference frequency) or a 7. 5 MHz (5.0 MHz Doppler reference frequency) linear array probe. The vascularity within or at the periphery of the mass was subjectively assessed from the CDI and Power Doppler images by two independent observers. It was assumed that the absence of vascularity indicated benignity and the presence of flow malignancy. RESULTS: CDI showed sensitivities of 62 and 42% and specificities of 62 and 62% using the 5 and 7.5 MHz probes respectively. PDI showed sensitivities of 76 and 51% and specificities of 56 and 48% using the 5 and 7.5 MHz probes respectively. A comparison of images of the 59 lesions investigated with both probes on both CDI and PDI concluded that the 5 MHz (3.75 MHz DRF) probe displayed equal vascularity to the 7.5 MHz (5.0 MHz DRF) probe in 76% of cases and greater vascularity in 24% of cases on CDI, and 68 and 31% of cases respectively on PDI. CONCLUSION: Power Doppler imaging with a 5 MHz (3.75 MHz DRF) probe increases the sensitivity of Doppler ultrasound to malignant breast tumours but the sensitivity achieved is not high enough to propose it as a screening investigation.

Complications of latissimus dorsi myocutaneous flap breast reconstruction.

AIMS: To review the experience of a single unit in post-mastectomy reconstruction using the latissimus dorsi flap. METHODS: A retrospective review of 111 cases treated between 1984 and 1993. The notes were evaluated for type of procedure, associated treatment and complications. RESULTS: A significant morbidity of this procedure was demonstrated with 41 (37%) patients requiring a second operation during the period of the study. The majority of these second operations were related to the prosthesis used to achieve symmetry. Second operations were more common in those who had saline-filled prostheses. Other complications seen included wound infection, small areas of flap necrosis, hypertrophic scars and problems with the donor scar. No differences in complication rates were demonstrated for delayed vs immediate procedures or for patients receiving or not receiving radiotherapy. No life-threatening complication were seen during the study. CONCLUSIONS: The latissimus dorsi reconstruction is reliable but the overall programme is beset with considerable morbidity. This factor needs to be taken into consideration when discussing reconstructive options with the post-mastectomy patient.

An international comparison of cancer survival: Toronto, Ontario, and Detroit, Michigan, metropolitan areas.

OBJECTIVES: This study examined whether socioeconomic status has a differential effect on the survival of adults diagnosed with cancer in Canada and the United States. METHODS: The Ontario Cancer Registry and the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program provided a total of 58,202 and 76,055 population-based primary malignant cancer cases for Toronto, Ontario, and Detroit, Mich, respectively. Socioeconomic data for each person's residence at time of diagnosis were taken from population censuses. RESULTS: In the US cohort, there was a significant association between socioeconomic status and survival for 12 of the 15 most common cancer sites; in the Canadian cohort, there was no such association for 12 of the 15 sites. Among residents of low-income areas, persons in Toronto experienced a survival advantage for 13 of 15 cancer sites at 1- and 5-year follow-up. No such between-country differentials were observed in the middle- or high-income groups. CONCLUSIONS: The consistent pattern of a survival advantage in Canada observed across various cancer sites and follow-up periods suggests that Canada's more equitable access to preventive and therapeutic health care services is responsible for the difference.

Evaluation of general practitioner referrals to a specialist breast clinic according to the UK national guidelines.

The recently published national guidelines to general practitioners for the referral of patients with breast problems were retrospectively applied to letters of all patients attending the Rapid Access Breast Clinic at the University Hospital of Wales. The patients have all had diagnostic investigations performed at the initial visit with a multidisciplinary review of results and provision of a management plan prior to the subsequent visit. Since its inception in May 1995 until the end of the year when the guidelines were published, 2332 new patients had been seen. Overall, 29% of patients with benign breast disease would not have been referred if the guidelines had been strictly followed. Of the 147 symptomatic carcinomas diagnosed from general practitioner referrals (6.3% of total referrals), no invasive cancers would have been missed. One patient with incidental detection of ductal carcinoma in situ (DCIS) in the asymptomatic contralateral breast would not have been referred. Referral for pain without a discrete lump constituted 63% of the patients with a benign diagnosis who fell outside the guidelines. The guidelines also include comprehensive algorithms for the initial management of benign breast symptoms that do not require immediate referral by the general practitioners. Our general practitioners were significantly better at referring patients over 50 years old but the proportion of appropriate referrals were not related to the number referred by each practice. The present guidelines adequately cover referral for the diagnosis of malignant breast disease to a specialist, and may reduce the benign workload of breast clinics.

A randomised phase III cross-over study of tamoxifen versus megestrol acetate in advanced and recurrent breast cancer.

139 peri- and postmenopausal women with advanced or recurrent breast cancer who had not received prior hormonal therapy were randomised in an open, cross-over study comparing the synthetic progestogen megestrol acetate with tamoxifen. The response rate (CR/PR) to megestrol acetate (25%; 95% confidence interval (CI) 15-35%) was not significantly different from that produced by tamoxifen (33%, CI 22-44%). Time-to-treatment failure was also similar in the two groups. Cross-over treatment was given on progression in 76 cases. Cross-over response (CR/PR) was seen in 3 of 35 patients (9%) receiving megestrol acetate as second-line therapy and in 6 of 41 patients (15%) receiving tamoxifen second-line. There was no significant difference in survival between the groups (P = 0.17) with median survival times of 24 and 32 months for the megestrol acetate and tamoxifen groups, respectively. The toxicity profile of the two drugs was different, although significant toxicity was rare with either agent. Megestrol acetate is an effective treatment for advanced breast cancer in older women when used either as first- or second-line treatment. Cross-over response is seen following both treatments. Given that most patients now receive tamoxifen as adjuvant treatment, megestrol acetate would appear to be one of the logical choices for patients who find the side-effects of tamoxifen unacceptable and for those who relapse on tamoxifen with further hormone therapy being clinically indicated.
