Improvements in breast cancer pathology practices among medicare patients undergoing unilateral extended simple mastectomy.

The information contained in pathology reports of breast cancer specimens is of critical importance to treating physicians for selection of local regional treatment, adjuvant therapy, evaluation of therapy, estimation of prognosis, and analysis of outcomes. This information is also of great importance to patients and their families. In 2000, a Breast Cancer Pathology Advisory Group was formed to advise on the design of a project to assess the quality of pathology reports on unilateral extended simple mastectomy (ICD-9-CM procedure code 85.43) specimens from Medicare patients in New York State. This group comprised clinical pathologists, breast surgeons, medical oncologists, clinical breast cancer specialists, and a radiation oncologist. The group suggested that the reports be examined for several elements (quality indicators) that are relevant to patient care and prognosis. Baseline random sample data assessing these elements were established from a random sample of all cases for the calendar year 1999. A random sample of 748 cases (43.5%) of unilateral extended simple mastectomy was chosen from among 1718 cases for the calendar year 1999. Of these, 555 (74.2%) were suitable for review. The remaining 193 (25.8%) cases did not satisfy the inclusion criteria. Aggregate performance on 7 quality indicators (presence of carcinoma, laterality of specimen, number of lymph nodes present, number of positive nodes, documentation of lymph nodes, histologic type, and largest dimension of the tumor) was 83.7% or better, whereas performance was 69.4% or less on 10 others (resection margin status, verification of tumor size, gross observation of the lesion, histologic grade, angiolymphatic invasion, nuclear grade, location of the tumor, mitotic rate, extent of tubule formation, and perineural invasion). The last, perineural invasion, was used as a control element and was not considered an evaluative quality indicator. Performance levels for New York State were significantly lower for histologic grade, resection margin status, and angiolymphatic invasion than in similar studies elsewhere. In addition, there were significant interhospital disparities in the performance levels for these quality indicators. Whereas some hospitals always recorded certain indicators, others never did. This in part reflects differing degrees of adoption of recommended specialty society protocols. The second phase of the project consisted of an educational feedback program involving the directors of pathology laboratories in New York State. The aggregate findings of the baseline study were shared with all the pathologists. In addition, each hospital that performed unilateral extended simple mastectomies during the study period received its own specific data so that it could compare its performance with the aggregate performance. The results of the baseline study also were shared with the New York Pathological Society and the New York State Society of Pathologists. The latter described the results in its newsletter. A postintervention review of the medical charts of a sample of 297 Medicare patients discharged from New York State acute care hospitals with an ICD-9-CM procedure code of 85.43 (unilateral extended simple mastectomy) was conducted for the 6-month period from December 1, 2001, through May 31, 2002. The 8 quality indicators, performance for which was below 84% in the baseline, were chosen for this remeasurement. Statistically significant improvements (P < .0001) occurred in all the 8 quality indicators, ranging from 12.6% to 19.9%. The results of this study indicate that the issues identified by breast cancer pathology reports are amenable to improvement. Such improvement can serve both the patients and the treating physicians better in making adjuvant treatment decisions, estimating prognosis, and evaluating outcomes. It also will be of help to patients and their families in making other life decisions.

A comparison between the results of simple mastectomy and tumorectomy for breast cancer: the problem of local recurrence.

Between 1963 and 1981, 1139 patients had surgery for unilateral breast cancer at the Charlottenburg Gynaecological Clinic of the Free University Berlin. A total of 948 patients had a simple mastectomy and 191 patients had an extended tumorectomy (or lumpectomy) with subsequent radiotherapy (40 Gy). Retrospective analysis of "matched cases" treated by tumorectomy or mastectomy showed the rate of local recurrence after tumorectomy to be nearly double that after simple mastectomy (8.7% after tumorectomy, 4.7% after mastectomy). Life expectancy with a local recurrence after conservative surgery, was however, better than that after simple mastectomy.

A prospective audit of simple mastectomy under local anaesthesia.

The treatment options for breast cancer in elderly or unfit patients can be complicated by their coexistent medical problems. This study assesses the feasibility of simple mastectomy under local anaesthesia by means of a prospective audit on 36 patients with breast carcinoma and an ASA grade of 3 or worse. In 27 patients the tumour had escaped from tamoxifen control, no patients having had previous radiotherapy. Operation time ranged from 40 to 70 min, average blood loss was 200 ml and an average inpatient stay of 5 days. Only two patients had a resection margin less than 1 cm and in none was there significant morbidity or mortality despite the patients' poor pre-operative medical condition. This confirms the potential of using local anaesthetic for simple mastectomy. Eliminating the morbidity/mortality due to general anaesthesia widens the range of treatment available (especially to medically unfit patients) giving them the option of a rapid resolution to what could be a distressing protracted condition.

Local recurrence after simple mastectomy.

A retrospective study was carried out to determine the clinical significance of local recurrence after simple mastectomy and node biopsy for primary operable breast cancer, without postoperative irradiation or systemic adjuvant therapy. Local recurrence was defined as a histologically proven lesion in or deep to the mastectomy skin flaps. A total of 966 patients with a median follow-up of 7 years were reviewed. Of these, 223 (23 per cent) developed local recurrence but half the tumours were small single lesions; 70 women had multiple discrete lesions and 21 diffuse carcinomatous dermal infiltration. Local recurrence showed significant associations with tumour grade, nodal status and the presence of lymphovascular invasion in the primary tumour. A predictive index containing these three variables was constructed. Adjuvant irradiation of the flaps is recommended for patients with high scores; such women would otherwise have a 39 per cent chance of developing local recurrence by 5 years. Different types of local recurrence have different chances of responding to local therapy: 13 per cent of single local recurrences, 32 per cent of multiple spot recurrences and 70 per cent of the diffuse type failed to respond to local therapy. Local recurrence predicts reduced patient survival.

A comparison between suction and corrugated drainage after simple mastectomy: a report of a controlled trial.

A randomized prospective trial of closed suction wound drainage compared with corrugated wound drainage after simple mastectomy for early breast cancer (lesion confined to the breast and without skin ulceration) is reported. Fifty-one patients were admitted to the study and there was no difference between the two groups with respect to local complications such as ifection, skin necrosis and collection under flaps and wound healing. Dressings require to be performed significantly less frequently with suction as opposed to corrugated drainage and suction drains were removed significantly sooner than corrugated drains. It is concluded that closed suction wound drainage should be used after simple mastectomy.

Simple mastectomy and axillary node sampling (pectoral node biopsy) in the management of primary breast cancer.

Axillary node sampling was introduced as a means of defining those patients whose primary breast cancer was treated by simple mastectomy in whom postoperative radiotherapy could be avoided safely. The authors have initiated controlled randomized trials in Cardiff and Edinburgh which have indicated that, provided that nodes are identified for histologic examination, simple mastectomy, node sampling, and selective radiotherapy give equal survival rates to routine radical treatment, whether this is by surgery or radiotherapy. Provided sampling of nodes is adequate and histologically proven, locoregional control also is satisfactory. A current randomized trial comparing this policy with Patey mastectomy has allowed comparative studies of axillary node status. These and follow-up data indicate that for a valid assessment, three to four nodes should be identified by the surgeon for histologic examination, the false negative rate being less than 10%.

Simple mastectomy with postoperative irradiation versus extended radical mastectomy in breast cancer. A twenty-five-year follow-up of a randomized trial.

From November 1951 to December 1957, all patients with untreated breast cancer admitted to the Radium Centre in Copenhagen were randomized before their operability was evaluated into two groups, if the patients were operable, viz. simple mastectomy with postoperative x-ray treatment or extended radical mastectomy. Twenty-five-year results are presented, showing no difference in survival or recurrence-free survival of the operable patients. Histological grading was performed in nearly all cases. Patients with grade 1 tumours had a better survival than grades 2 and 3, but there was no difference in survival between the two treatment groups, when histological grading was taken into account. Histological node positive patients had more grades 2 and 3, tumours, whereas node negative patients had more grade 1 than grades 2 and 3 tumours. Premenopausal women had a significantly better survival than postmenopausal in all stages.

Simple mastectomy under local anaesthesia.

Nine patients with locally advanced carcinoma of the breast underwent simple mastectomy under regional anaesthesia (1% lignocaine and 1:100,000 adrenaline). Preoperative sedation was provided by oral lorazepam. There were no technical problems, evidence of lignocaine toxicity or excessive operative blood loss and no wounds became infected.

One-stage simple mastectomy with immediate reconstruction for high-risk patients. An improved technique: the biologic basis for ductal-glandular mastectomy.

The heterogeneity of human breast carcinoma appears to be a cumulative interrelationship of genetic and environmental factors that may be identifiable with a high risk for carcinogenesis. Until breast cancer prevention is realized, one-stage total ductal-glandular mastectomy with immediate reconstruction may be offered as an alternative to simple mastectomy for women at high risk for developing cancer. This technique affords the complete extirpation of breast tissue at a deep plane with flaps that are identical in thickness to those elevated in classic mastectomies for invasive cancer. Breast reconstruction with submuscular prostheses in a one-stage procedure gives an aesthetically acceptable result. The role of ductal-glandular mastectomy as prophylaxis for invasive carcinoma warrants future prospective trials.

Breast reconstruction with submuscular prosthesis after modified radical or simple mastectomy. Surgical technique and early complications.

A series of 100 women who underwent breast reconstruction is reviewed. They had previously been treated for breast cancer with modified radical or simple mastectomy. The technique and early results of reconstruction are presented. The same surgeon performed all these operations and the technique was not varied. Emotional need for reconstruction was the main factor in patient selection. The interval between mastectomy and reconstruction was as a rule at least one year after removal of stage I cancer and 2-5 years in stage II cases. Scar correction was required significantly more often after oblique than after horizontal mastectomy incision. A submuscular pocket was created to accommodate the prosthesis and a muscle and fascia flap was used to add tissue and contour. No major early complications occurred. The submuscular implantation of prosthesis facilitated clinical follow-up. In a background population of breast cancer patients, the overall frequency of breast reconstruction was 4%. The figure for premenopausal patients with stage I breast cancer treated with modified radical mastectomy was 18%.
