Repeated adjuvant chemotherapy with phenylalanine mustard or 5-fluorouracil, cyclophosphamide, and prednisone with or without radiation, after mastectomy for breast cancer.

172 patients who had had mastectomy for breast cancer were treated by repeated adjuvant chemotherapy, either with phenylalanine mustard (P.A.M.) or a combination of cyclophosphamide, 5-fluorouracil, and prednisone (C.F.P.) with and without radiotherapy. Tumours recurred significantly more frequently and mortality tended to be higher in P.A.M.-treated patients than in patients on other treatment. The interval between surgery and disease recurrence was significantly shorter for P.A.M.-treated premenopausal but not postmenopausal patients than for patients of equivalent menstrual status treated with C.F.P. with or without radiation. The associations in premenopausal patients between the mode of treatment and both survival and the disease-free interval were significant before and after adjustment for variations between the treatment groups in the number of involved lymph nodes and the size of the primary tumour.

Myocardial perfusion imaging in breast cancer patients treated with or without post-mastectomy radiotherapy.

PURPOSE: To assess the occurrence and location of myocardial perfusion defects in left-sided mastectomized breast cancer patients, treated with or without postoperative radiotherapy according to the guidelines from the Danish Breast Cancer Cooperative Group (DBCG). PATIENTS AND METHODS: Seventeen left-sided breast cancer patients, with a median age of 59 years (range, 47-75 years), randomized to post-mastectomy irradiation plus systemic treatment, or systemic treatment alone, were examined after a median follow-up of 7.9 years (range, 6.0-12.2 years). The chest wall and the ipsilateral internal mammary nodes had been treated through two anterior-shaped electron fields, and the electron energy was chosen according to chest wall thickness, measured individually by ultrasound. The median absorbed dose was 50 Gy in 25 fractions, with 5 fractions/week. Information on clinical history was obtained and symptoms of ischemic heart disease (IHD), as well as major risk factors, were recorded. All patients had a physical examination, blood chemistry, electrocardiogram (ECG), chest X-ray and myocardial perfusion imaging by sestamibi-single photon emission computerized tomography (SPECT). SPECT-scanning was performed as a rest/dipyridamole 2-day protocol. The evaluation of regional myocardial perfusion was based on scintigrams using a 20-segment model. RESULTS: There was no significant difference between the scintigraphic findings in the two groups. Four of ten irradiated patients and four of seven non-irradiated patients showed scintigraphic defects. An anterior defect was found in one non-irradiated patient. CONCLUSIONS: This study does not indicate that the described radiotherapy technique induces detectable coronary artery disease. However, the small number of patients does not allow strong conclusions to be drawn.

The severity of late skin damage related to fraction size in women treated by radiotherapy after mastectomy.

A retrospective study has been undertaken to test the NSD formula as a predictor of isoeffective schedules in women treated after mastectomy by parasternal radiotherapy using fraction sizes of 2-3 Gy. Forty three women were identified who have been treated on the same orthovoltage unit 8-18 years previously and the severity of overall skin changes and telangiectasia were assessed by three observers using a 4-point categorical scale. At each level of skin damage, radiotherapy schedules delivered using fraction sizes of 250 R or 300 R were associated with lower TDF values than schedules using 225 R fraction. The difference between TDF factors for isoeffective regimes using small (225 R) and large (250 R and 300 R) fraction sizes is highly significant for both overall skin damage and telangiectasia (p = 0.004 by rank sum test). Care should be exercised when using current empirical formulae to calculate regimes isoeffective for late skin damage, even when modest changes in fraction size from 2 to 3 Gy are contemplated.

Loco-regional recurrences after mastectomy in breast cancer: prognostic factors and implications for postoperative irradiation.

PURPOSE: Potential risk factors including DNA flow cytometric-derived parameters predicting loco-regional recurrence (LRR) in early breast cancer were investigated. MATERIALS AND METHODS: This study included 608 patients treated by modified radical mastectomy between 1982 and 1987. Recommendations regarding local treatment as well as adjuvant systemic therapy did not change during this period. Patients treated by adjuvant chemotherapy were randomized to receive additional medroxyprogesterone acetate (MPA) treatment. Only 59 (10%) patients received postoperative irradiation (XRT) to the chest wall and/or axillary lymph nodes; another 121 (20%) patients received XRT to the internal mammary nodes because of centromedially located tumours. RESULTS: Patients were followed for a median period of 7.5 years. The event-free survival at 10 years was 50%. The cumulative incidence rate of LRR at 10 years was 18% (n = 93), either with (n = 30) or without (n = 63) concurrent distant metastases. The chest wall, regional lymph nodes or both were involved in 41 (44%), 38 (41%) and 12 (13%) patients, respectively. Multivariate analysis according to the Cox model revealed two factors associated with LRR, i.e. pT (P < 0.05) and nodal status (P < 0.05). In node-positive patients extracapsular tumour extension (ECE) and pT were independent risk factors. DNA ploidy and S-phase fraction did not yield additional information. Based on pT, nodal status and extracapsular extension of tumour growth a high risk (> 10%) and low risk (< 10%) group for LRR could be identified. CONCLUSIONS: Results indicate that T-stage and nodal status, combined with ECE, may help to identify patients at risk for loco-regional recurrence, whereas DNA flow cytometry does not.

Post-mastectomy radiotherapy in pT3N0M0 breast cancer: is it needed?

BACKGROUND AND PURPOSE: It is not been established whether breast cancer patients who have a primary tumor 5 cm or larger but no axillary nodal or distant metastases at the time of the diagnosis (pT3N0M0) benefit from post-operative radiation therapy after mastectomy. MATERIAL AND METHODS: We identified 81 patients with T3N0M0 breast cancer out of the total of 4190 breast cancer patients treated in one university radiotherapy department from 1987 to 1994 from the department patient registry, and examined the clinical records and histopathological slides. RESULTS: Only 38 of the 81 patients had true pT3N0M0 breast cancer after the review (0.9% of the 4190 new breast cancer patients registered in the department from 1987 to 1994). Three (60%) of the five patients who were not treated with post-operative radiation therapy developed locoregional recurrence of breast cancer as compared with only three (9%) of the 33 patients who were given post-operative radiotherapy during a median follow-up of 58 months (P = 0.0003). Patients who were given post-operative radiotherapy had a better distant disease-free survival rate (P = 0.04) and overall survival rate (P = 0.03) than the ones who were not treated with radiation therapy after surgery. Of the 29 patients who had chest wall irradiation only, one had in-field recurrence at the surgical scar, one both at the scar and the unirradiated axilla, and only one (3%) solely in the axilla. CONCLUSIONS: Patients with true pT3N0M0 breast cancer are rare. The results suggest that women with pT3N0M0 breast cancer benefit from post-operative radiotherapy, but the value of irradiating the dissected ipsilateral axilla remains unsettled.

Lymphangioma circumscriptum following mastectomy and radiation therapy.

We describe a woman who developed clear, tense vesicles in an area of chronic lymphedema 8 years following mastectomy and radiation therapy. The vesicles showed the clinical and pathologic features of lymphangioma circumscriptum, which can develop as a late sequelae of the lymphatic damage inherent in some forms of cancer therapy.

Recurrent pemphigus vulgaris limited to the surgical area after mastectomy.

A 45-year-old Japanese female presented with bullae and erosions on the trunk in December 1987. The histologic findings revealed a suprabasal cleft and acantholytic cells. Immunofluorescence staining showed IgG autoantibodies in the intercellular spaces. With a working diagnosis of pemphigus vulgaris, she was treated successfully with low dosage prednisolone. Adenocarcinoma of the right breast was found in March 1994, and she received a mastectomy followed by breast reconstruction that used a transverse rectus abdominis muscle flap. Six months later, vesicobullous eruptions developed and were limited to the surgical area (right chest and abdomen). The histopathologic and direct immunofluorescence findings were consistent with pemphigus vulgaris. Although these skin lesions improved with high dosages of prednisolone, she died of multiple metastases due to the breast cancer.

[Stewart-Treves syndrome following mastectomy for breast cancer: a case report].

INTRODUCTION: Stewart-Treves syndrome has been defined by the eponymous authors as a lymphangiosarcoma in a setting of postmastectomy upper extremity lymphoedema. EXEGESIS: The clinical record of one patient with Stewart-Treves syndrome is analyzed. The primary angiosarcoma of the skin represented by a purple nodule occurred on a chronic lymphoedematous arm following radical mastectomy and axillary lymph node dissection for breast carcinoma performed 9 years earlier. Immunohistochemistry tests formally eliminated epithelial cutaneous metastasis and produced evidence in favour of conjunctive vascular tissue origin of the tumor. CONCLUSION: Conservative surgery for breast cancer, application of axillary sentinel node biopsy in the lymphatic staging and prevention of arm lymphoedema should reduce the incidence of this syndrome.

Immediate breast reconstruction with deepidermalized transverse rectus abdominis musculocutaneous flap after skin-sparing mastectomy.

Use of the transverse rectus abdominis musculocutaneous (TRAM) flap for breast reconstruction is widely accepted and indications have been well-defined over the past years. More recently, the moratorium prohibiting pre-filled silicone gel implants both in esthetic surgery and in reconstruction breast surgery, has incited more and more patients to refuse prostheses, even saline filled implants. Total mastectomy with skin-sparing technique, beyond the limitations dictated by oncology factors which must be taken into account because of the risk of local recurrence, raises the question of immediate breast reconstruction since implants, when possible, may give unsatisfactory results either more or less short-term. The deepidermalized TRAM flap is an interesting alternative for selected patients, especially those with an adapted abdominal morphology, allowing stable and natural autologous breast reconstruction.

Nevus cells in axillary lymph nodes from radical mastectomy specimens.

From 1977 to 1983, 44 cases with nevus cells in the capsule and trabeculae of axillary lymph node specimens from about 7000 mastectomies performed for primary breast cancer were found. This finding was therefore less than 1%. In 3 cases, the nevus cells were present in 2 nodes, whereas in 41 cases solitary nodes were involved. In 13 cases, nevus cells were present in nodes that also contained metastatic carcinoma. Silver impregnation of reticulin fibers is very useful for the differential diagnosis of nodal metastases of breast carcinoma.

Pathologic tumor size and lymph node status predict for different rates of locoregional recurrence after mastectomy for breast cancer patients treated with neoadjuvant versus adjuvant chemotherapy.

PURPOSE: To compare the pathologic factors associated with postmastectomy locoregional recurrence (LRR) in breast cancer patients not receiving radiation who were treated with neoadjuvant chemotherapy (NEO) vs. adjuvant chemotherapy (ADJ). METHODS AND MATERIALS: We retrospectively analyzed the rates of LRR of subsets of women treated in prospective trials who underwent mastectomy and received chemotherapy but not radiation. These trials were designed to answer chemotherapy questions. There were 150 patients in the NEO group and 1031 patients in the ADJ group. In the NEO group, 55% had clinical Stage IIIA or higher vs. 9% in the ADJ group (p <0.001, chi-square test). RESULTS: Despite the more advanced clinical stage in the NEO group, the pathologic size of the primary tumor and the number of positive lymph nodes (+LNs) were significantly less in the NEO group than in the ADJ group (p <0.001 for both comparisons). However, the 5-year actuarial LRR rate was 27% for the NEO group vs. 15% for the ADJ group (p = 0.001, log-rank). The 5-year risk for LRR was higher in the NEO patients for all pathologic tumor sizes: 0-2 cm (18% vs. 8%, p = 0.011), 2.1-5 cm (36% vs. 15%, p <0.001), and >5 cm (46% vs. 28%, p = 0.028). The risk of LRR by the number of +LNs was similar in the NEO and ADJ groups, except for the subset of patients with > or =4 +LNs (53% vs. 23%, p <0.001). The rates of LRR in the patients with primary tumors measuring < or =2.0 cm and 1-3 +LNs were similar in both groups. However, for the patients with a pathologic tumor size of 2.1-5.0 cm and 1-3 +LNs, the LRR was higher in the NEO group than in the ADJ group (30% vs. 15%, p = 0.016). Most failures in this NEO subgroup had clinical Stage III disease. In a subset of NEO and ADJ patients matched for clinical stage, no significant differences were found in the rates of LRR according to primary tumor size and number of +LNs when these variables were analyzed independently. Again, however, differences were found in the subgroup of patients with tumors pathologically measuring 2.1-5.0 cm with 1-3 +LNs (32% NEO vs. 8% ADJ, p = 0.030). CONCLUSION: The rates of postmastectomy LRR for any pathologic tumor size are higher for patients treated with initial chemotherapy than for patients treated with initial surgery. Radiotherapy should be offered to all patients with > or =4 +LNs, tumor size >5 cm, or clinical Stage IIIA or greater disease, regardless of whether they receive neoadjuvant or postoperative chemotherapy. The information assessing LRR rates in patients with clinical Stage II disease who receive neoadjuvant chemotherapy, particularly if 1-3 lymph nodes remain pathologically involved, is insufficient to determine whether these patients should receive radiotherapy.

Quality control in health care: an experiment in radiotherapy planning for breast cancer patients after mastectomy.

PURPOSE: The importance of evaluating and improving quality in clinical practice is now generally acknowledged. In this study we estimated different sources of variation in radiotherapy planning for breast cancer patients after mastectomy and sought to test the applicability of a reproducibility and repeatability (R&R) study in a clinical context. METHODS: Eleven radiation oncologists planned radiotherapy three times for three different kinds of breast cancer patients without knowing they were handling the same patient three times. Variation was divided into different components: physicians as operators, patients as parts, and repeated measurements as trials. Variation due to difference across trials (repeatability), that across the physicians (reproducibility), and that across the patients (variability) were estimated, as well as interactions between physicians and patients. Calculation was based on the sum of squares, and analysis was supported by various graphical presentations such as range charts and box plots. RESULTS: Some parts of the planning process were characterized by higher and different kinds of variation than the others. Interphysician variation (i.e., reproducibility) was not high but there were some clearly outlying physicians. The highest variation was in repeatability (= intraphysician variation). The major part of the variation was, however, that from patient to patient: 33% of the total in Parameter 1 and 85% of the total in Parameter 2. CONCLUSIONS: R&R studies are applicable and are needed to evaluate and improve quality in clinical practice. This kind of analysis provides opportunities to establish which kinds of patients require particularly careful attention, which points in the process are most critical for variation, which are the most difficult aspects for each physician and call for more careful description in documents, and which physicians need further training.

Motivations, satisfaction, and information of immediate breast reconstruction following mastectomy.

This study evaluated patients' motivations for, and satisfaction with, the treatment and information of immediate breast reconstruction (IBR) with a silicone prosthesis. It studied satisfaction more deeply by relating it to the quality of life, body-image and sexual functioning. Seventy-three patients who received mastectomy, followed by IBR with a subpectoral silicone prosthesis, completed a self-report questionnaire concerning their motivations for, perceived advantages of and satisfaction with IBR, the information received, quality of life, body image, and sexual functioning. Despite the fact that 50% of the reconstructions resulted in complications or complaints, 70% of the women were satisfied with the reconstruction and only 12% would never choose IBR again. Satisfaction was strongly correlated with the need for information. The higher the patient's expectations, the higher their need for information. The most common perceived advantage of IBR was the avoidance of an external prosthesis. A majority of patients were satisfied with the breast reconstruction. However, a sizeable proportion needed more information about breast reconstruction and the use of the silicone prosthesis. To avoid too high expectations more attention should be given to possible complications and the moderate cosmetic results.

Mastectomy and immediate breast reconstruction: oncological considerations and evaluation of two different methods relating to 88 cases.

The authors consider 88 cases of mastectomy and immediate breast reconstruction mainly performed using the skin expander plus prosthesis method or latissimus dorsi myocutaneous flaps. At the same time, 53 patients underwent contralateral mastopexy for symmetry. The mean follow-up was 21 months (range 2-102). Progressive disease was observed in nine cases: one patient presented scar relapse, one axillary relapse, two contralateral tumor, two contralateral tumor and distant metastasis, three distant metastases and one death from distant metastasis. Reconstruction complications were capsular contracture in 12 cases, infection in nine, skin necrosis in two, skin expander breakage in three and implant dislocation in one. The final result was judged good in 54 cases, fair in nine, poor in 11 and unevaluable in 14. In conclusion immediate breast reconstruction does not seem to interfere with the disease or oncological therapy. After analysing separately, and comparing the results and complications of the two main techniques used, latissimus dorsi seems to be the most reliable method in the majority of cases but skin expanders can be a good technique in patients with small and firm breasts and without complicating risk factors.

A comparison of two surgical techniques for performing mastectomy.

Most surgeons performing mastectomy (MRM) use either the scalpel or electrocautery for developing flaps and performing node dissection. We report a retrospective analysis of all MRM performed over a five-year period by two surgical oncologists. One-hundred-and-ninety-six cases met criteria for inclusion into the study. There are 110 patients in the electrocautery (EC) group and 86 patients in the scalpel (Scpl) group. Mean patient age, mean specimen weight and mean number of lymph nodes removed were not significantly different for the two groups. The incidence of complications was similar for the two groups. Mean estimated blood loss was 134.1 cc for the EC group and 331.6 cc for the Scpl group (P < 0.001). Estimated blood loss ranged from 25 to 475 cc for EC group and from 88 to 1350 cc for the Scpl group. One patient in the Scpl group required transfusion. Mean operating time was less for the Scpl group, 111.0 vs 93.5 minutes (P < 0.009). Multiple regression analysis revealed that technique was the strongest predictor of estimated blood loss (standardized coefficient 0.61). Operating time, age, number of nodes removed and specimen weight were less predictive (standardized coefficient 0.21, 0.17, 0.11 and 0.09, respectively).

Fear of mastectomy: the most common factor responsible for late presentation of carcinoma of the breast in Nigeria.

Of 2154 Nigerian breast cancer patients of all ages and socio-economic groups, 87% presented in Stages III or IV and only 13% in Stages I or II. All were questioned on their reasons for not attending hospital sooner. Questionnaires were used and were adequately translated to illiterate patients. The most common reason for delay (963 patients, 44.7%) was fear of mastectomy. Other reasons given include preference for prayer houses or spiritual healing homes in 291 patients (13.5%) a belief that the lesion was inflammatory in 183 (8.5%), preference for native doctors or herbalists in 497 (23.1%) and economic reasons in 220 (10.2%).

Thoracic epidural anesthesia for modified radical mastectomy in a patient with cryptogenic fibrosing alveolitis: a case report.

A case of advanced cryptogenic fibrosing alveolitis (CFA) with multiple bullae and extensive pulmonary fibrosis, scheduled for modified radical mastectomy for carcinoma of breast, is presented. This patient had ischemic heart disease, corticosteroid-induced hypertension, diabetes mellitus, and a difficult airway. Thoracic epidural segmental anesthesia was successfully given to this patient. Preoperative problems, perioperative management, and alternative anesthetic techniques are discussed.

Treatment of operable breast cancer in the elderly: a randomised clinical trial EORTC 10850 comparing modified radical mastectomy with tumorectomy plus tamoxifen.

We have examined the outcome of older patients with operable breast cancer treated in a randomised trial by either standard surgery or less extensive surgery and tamoxifen. There were 236 participants aged >/=70 years, randomised to either modified radical mastectomy MRM (n=120) or wide local excision (WLE) and tamoxifen (T) 20 mg daily (n=116). Survival curves were estimated using the Kaplan-Meier method and multivariate analyses were performed using Cox's proportional hazards model. Endpoints were survival and time to first relapse or progression, loco-regional progression, time to distant progression and progression-free survival. No significant difference was seen in terms of progression-free survival, but there were significantly more loco-regional relapses in the WLE+T group. In contrast, there were more distant metastases in the MRM group, but with a similar overall survival in both groups. The results of this trial give cautious support for the use of WLE+T for selected older women.
