A case of stromal sarcoma of the breast occurring after augmentation mammaplasty

The first case of stromal sarcoma of breast occurring after augmentation mammaplasty is reported. The patient is 55-year-old Japanese woman who had received injection augmentation mammaplasty 19 years earlier. Both breasts indurated soon after mammaplasty and the patient felt a severe pain in her right breast for about 6 months before seeking treatment. Stromal sarcoma of the breast was proven by a subcutaneous mastectomy, and the determined histological subclassification was a malignant fibrous histiocytoma (MFH). The patient died with tumor recurrence 14 months after her first admission. The tumor cells were found to have invaded the surrounding tissue, such as the nerves, the muscle, the lymphatic vessels, and a severe reactive inflammation, caused by the injected material, was noticed.     

Analysis of radiation pneumonitis and radiation-induced lung fibrosis in breast cancer patients after breast conservation treatment

We examined radiation pneumonitis in breast cancer patients after breast conservation treatment (BCT) and analysed the degree of radiation-induced lung fibrosis by computed tomographies of the chest (chest CT). Fifty-two breast cancer patients were treated with BCT, including breast irradiation and chemotherapy. These patients symptomatic of radiation pneumonitis were examined every two to four weeks. Chest X-rays and chest CT were performed about one year after irradiation. symptoms due to radiation pneumonitis was registered in 9.6% of patients. lungs showed fibrotic changes by chest CT in 90% of the cases. Concurrent or alternative chemotherapy increased the incidence of symptomatic radiation pneumonitis and, to a certain extent, the degree of fibrotic change in the lung after BCT.     

Angiosarcoma of the breast after conservation therapy for invasive cancer, the incidence and outcome. An unforeseen sequela

Purpose. In the past 15 years breast conserving therapy (BCT) has become an important treatment option for primary breast cancer. Thirty three angiosarcomas (AS) after BCT have been described in a total of 20 published reports. Limited follow-up data and the lack of information on incidence of AS prompted the authors to review the comprehensive experience in the Netherlands. Methods. Between 1987 and 1995 twenty-one patients with BCT-associated AS were diagnosed in the Netherlands. Follow-up after diagnosis of AS ranged from 6 to 82 months with a median of 24 months. Information on the total number of patients treated with BCT and on the numbers of angiosarcoma in the breast was obtained. Results. The median interval between BCT and AS was 74 months (range: 29–106) and appeared to decrease with higher age. Detection of skin changes followed by incisional biopsy provided the diagnosis. Two year overall (OS) and disease free survivals were 72% (s.e. 10.9) and 35% (s.e. 10.7), respectively. Two year OS after initial complete surgical resection was 86% (s.e. 9.3) compared to 0% after incomplete resection of the AS (P=0.04). The estimated incidence of AS after BCT is 0.16%. Conclusions. BCT-associated AS arises after a relatively short interval. Although the incidence of AS is low, the absolute number of patients at risk is increasing. This calls for vigilance concerning skin changes occurring after BCT. An incisional biopsy provides the only reliable diagnosis. The prognosis appears to be related to the completeness of surgical resection.     

Breast-conserving treatment after neoadjuvant chemotherapy in large breast cancer

Several recent trials have demonstrated that neoadjuvant chemotherapy can allow more patients to successfully undergo breast-conserving treatment (BCT), and does not confer a survival disadvantage compared with standard adjuvant chemotherapy. In addition, the pathological response of primary breast tumors to neoadjuvant chemotherapy appears to be a surrogate marker for patient outcome. In our series, during the period from May 1995 to December 2000, 86 patients with tumors between 3.1 and 6.0 cm in diameter received epirubicin-based neoadjuvant chemotherapy. There were 55 (64.0%) responders and ultimately 64 patients (74.4%) were treated with BCT. The margin positive rate was 14.1%(9/64), similar to the rate after BCT for early-stage breast cancers, the largest diameter of which was smaller than 3 cm. At a median follow-up of 30 months, only 3 patients in the BCT group have developed local recurrence; the local recurrence rate appears to be comparable to that after BCT for early stage breast cancers. Long term follow-up is required, however, to establish whether this procedure is a safe alternative to mastectomy for patients with large breast cancers.     

Postirradiation soft tissue sarcoma occurring in breast cancer patients: Report of seven cases and results of combination chemotherapy

Seven cases of soft tissue sarcoma developing after primary or postoperative radiotherapy for breast carcinoma are reported. The sarcomas occurred within the irradiated volume, after a latent period of 4-26 years. These cases conform well to established criteria for the diagnosis of radiation-induced sarcoma. Chemotherapy, consisting of the four-drug combination CYVAD1C (cyclophosphamide, vincristine, adriamycin, DTIC) was employed in six of the seven patients. Only two of them achieved partial remission, lasting only 2 and 3 months, respectively. The effectiveness of adriamycin-containing chemotherapy regimens in soft tissue sarcomas as well as the remote hazard of radiation-related sarcoma in primary or postoperative breast irradiation are discussed.     

Radiation-induced sarcoma of the breast in a female adolescent. Case report with histologic and therapeutic considerations

A 14-year-old girl developed a radiation-induced sarcoma of the left breast after successful combined surgical and radiation therapy of a left adrenal carcinoma when she was 9 months old. The breast lesion was histologically described as a stromal sarcoma with fibrosarcomatous and myxosarcomatous areas. The second primary lesion and local recurrence of this was treated with surgery. At each recurrence the tumor became more aggressive both clinically and histologically, and eventually proved fatal.     

Breast-conserving therapy can be offered to women with prior breast augmentation

IntroductionBreast cancer in women with cosmetic breast implants is increasingly common. Over the past decade, there has been a push for mastectomy and reconstruction in these patients, based on a fear of poor aesthetic results from small breast volume, and radiation-induced capsular contracture. At the Paris Breast Centre, augmented women routinely undergo lumpectomy with whole-breast irradiation (BCT).Materials and methodsA consecutive cohort of 50 augmented women, who had attempted BCT for early breast cancer at our institution between 2003 and 2018, were retrospectively identified. Post-treatment complications, oncologic outcomes, capsular contracture rates, long-term cosmetic outcomes, and patient-reported outcomes were evaluated.ResultsThe median follow-up was 51 months. Margins were involved in 7 women (14%); 4 of whom underwent successful re-excision, and 3 had a mastectomy, for an early mastectomy rate of 6%. There were no early complications, nor cases of early implant loss. Long-term aesthetic results were evaluated using our 5-point scale: An excellent (5), or good (4) result was obtained in 68%. Significant capsular contracture (Baker grade 3 or 4) developed in 34%, of which, 5 women underwent capsulotomy and fat grafting; 4 of 5 downstaging their Baker grade. The estimated 5-year local recurrence rate was 2.3%. Ninety-five percent of participants would recommend BCT to augmented women.ConclusionBCT is feasible and safe in augmented women with good long-term aesthetic results, and should be considered to avoid unnecessary mastectomy.     

Radiation-induced sarcomas after breast cancer: experience of Institute Curie and review of literature]

Adjuvant radiotherapy to the breast plays a significant role in preventing local failure in women treated for early stage breast cancer. This fact is supported by multiple clinical trials demonstrating that adjuvant radiotherapy decreases the risk of local recurrence and increases the rate of breast preservation, and actually the rules of adjuvant breast irradiation are clearly established. Sarcomas are a rare but recognized complication of radiation therapy for breast carcinoma, and are associated with poor prognosis. The first case of a bone sarcoma after radiation therapy of breast cancer was described by Beck in 1922. In 1948, Cahan et al. defined the criteria for diagnosis of radiation-induced sarcoma. Since then, some studies have reported the incidence of radiation-induced sarcoma after radiotherapy for different cancers. This article reports and discusses the incidence, management and treatment outcome of radiation-induced sarcomas occurring after radiotherapy for breast cancer in our institute. The incidence, histology, latency of appearance, genesis, their treatment and the prognostic factors of these rare tumors are discussed and the literature is reviewed.     

Ipsilateral breast tumour recurrence in hereditary breast cancer following breast-conserving therapy

The overall rate of an ipsilateral breast tumour recurrence (IBTR) after breast-conserving therapy (BCT) ranges from 1% to 2% per year. Risk factors include young age but data on the impact of BRCA1/2 mutations or a definite positive family history for breast cancer are scarce. We investigated IBTR after BCT in patients with hereditary breast cancer (HBC). Through our family cancer clinic we identified 87 HBC patients, including 26 BRCA1/2 carriers, who underwent BCT between 1980 and 1995 (cases). They were compared to 174 patients with sporadic breast cancer (controls) also treated with BCT, matched for age and year of diagnosis. Median follow up was 6.1 years for the cases and 6.0 years for controls. Patient and tumour characteristics were similar in both groups. An IBTR was observed in 19 (21.8%) hereditary and 21 (12.1%) sporadic patients. In the hereditary patients more recurrences occurred elsewhere in the breast (21% versus 9.5%), suggestive of new primaries. Overall, the actuarial IBTR rate was similar at 2 years, but higher in hereditary as compared to sporadic patients at 5 years (14% versus 7%) and at 10 years (30% versus 16%) (P=0.05). Post-relapse and overall survival was not different between hereditary and sporadic cases. Hereditary breast cancer was therefore associated with a higher frequency of early (2-5 years) and late (>5 years) local recurrences following BCT. These data suggest an indication for long-term follow up in HBC and should be taken into account when additional 'risk-reducing' surgery after primary BCT is eventually considered.     

Postradiation malignant fibrous histiocytoma and osteosarcoma of a patient with high telomerase activities

BACKGROUND: An extremely rare case of postradiation malignant fibrous histiocytoma (MFH) and osteosarcoma (OS) secondary to radiation therapy for leukemia-related osteolytic lesions is presented. In addition, the telomere biology of these tumors was investigated. CASE REPORT: A 14-year-old boy was diagnosed with acute lymphocytic leukemia. The right tibia was irradiated at a total dose of 60 Gy, and the left tibia was irradiated at a total dose of 40 Gy. The left tibia developed MFH and the right tibia developed OS. RESULTS: Telomere reduction (MFH 70.2, OS 70.0%) and high telomerase activities (MFH 12.1, OS 17.7 TPG) were observed. These results reflect an aggressive feature of postradiation sarcomas. CONCLUSION: Prognosis for patients diagnosed with postradiation sarcoma is poor due to its aggressiveness. However, even if sarcoma occurs after irradiation in more than two fields in a single patient, improvements in prognosis are anticipated with appropriate chemotherapies and wide resection.     

Local therapy in BRCA1 and BRCA2 mutation carriers with operable breast cancer: comparison of breast conservation and mastectomy

Women with BRCA1 and BRCA2 mutations have an elevated risk of breast cancer and ovarian cancer, but also of developing second primary breast cancer. BRCA1/2 mutation carriers with breast cancer must choose between breast conservation (BCT) and mastectomy (M) yet data on outcomes are limited. The purpose of this study is to compare long-term outcome following BCT and M in BRCA1/2 carriers. 655 women with BRCA1/2 mutations diagnosed with breast cancer and treated with BCT (n = 302) or M (n = 353) were identified and underwent follow-up to assess local, regional, and systemic recurrence. Local failure as first failure was significantly more likely in those treated with BCT compared to M, with a cumulative estimated risk of 23.5 vs. 5.5%, respectively, at 15 years (P < 0.0001); 15-year estimates in carriers treated with BCT and chemotherapy was 11.9% (P = 0.08 when compared to M). Most events appeared to be second primary cancers rather than failure to control the primary tumor. The risk of contralateral breast cancer was high in all groups, exceeding 40%, but was not statistically significantly different by use of adjuvant radiotherapy (RT) or not, suggesting no added risk from scatter RT at 10 and 15 years. There were no differences seen in regional or systemic recurrences between the BCT and M groups, and no difference in overall survival. In conclusion, BRCA1/2 mutation carriers with breast cancer have similar survival whether treated with M or BCT. However, women undergoing BCT have an elevated risk of a second in-breast event that is significantly reduced in the presence of chemotherapy. Contralateral breast cancer events are very common.

The use of neoadjuvant therapy increases the rate of breast conservation in men with locally advanced breast cancer

BackgroundMale breast cancer (MBC) is often diagnosed at a later stage and with a more unfavorable tumor-to-breast ratio compared to women, prompting lower rates of breast conservation (BCT). We sought to assess the practice patterns of neoadjuvant therapy (NT) in MBC patients and the impact on BCT.MethodsMen with nonmetastatic, invasive breast cancer were identified from the National Cancer Database. Patients were categorized as having small (cT1/2) or locally advanced (cT3/4) tumors and by whether they received NT (which included endocrine or chemotherapy). Univariate and multivariable analyses were performed to assess patterns of NT use and rates BCT.ResultsOf 15,151 male patients, 4.8% received NT and 21.6% underwent BCT. NT was more common among males with cT3/4 tumors than those with cT1/2 tumors (8.2 vs. 2.1%, P < .001). Overall, unadjusted rates of BCT were higher for patients receiving NT in the cT3/4 subgroup (19.0 vs. 12.5%, P < .001), a difference which persisted on multivariable analysis. For all patients analyzed, overall survival (OS) did not differ between males who underwent NT and those who did not (110 vs. 122 months, P = .67), but NT was associated with poorer OS in both univariate and multivariate analyses for patients with cT3/4 tumors (both P < .01).ConclusionsMen with invasive breast cancer have an expected low rate of BCT, but NT appears to reduce the use of mastectomy in patients with locally advanced cancers. More work is needed to understand the impacts of BCT on locoregional recurrence and disease-free and overall survival for MBC.     

Breast-conservation treatment for bilateral breast cancer in five Japanese women

Between August 1989 and September 1999, breast-conservation treatment (BCT) was performed in 250 of 256 breast cancer patients. Five of the 250 patients had bilateral breast cancer, and 4 with synchronous bilateral breast cancer of the 5 were concomitantly treated by chemo-endocrine therapy before simultaneous breast-conservation surgery for bilateral breast cancer. Chemotherapy was performed using cyclophosphamide, pirarubicin, and 5-fluorouracil, while endocrine therapy was performed using an antiestrogen agent (tamoxifen or toremifene). All patients were also treated by radiotherapy. Since no severe side effects or complications were induced by these therapeutic approaches, bilateral breast cancer may be successfully treated by BCT as in unilateral breast cancer. However, of the 5 patients with bilateral breast cancer, cancer recurrence in the axillary lymph nodes was detected only in 1 patient with T2N1 cancer 78 months after simultaneous breast-conservation surgery for bilateral breast cancer.     

The safety of breast-conserving therapy in patients with breast cancer aged < or = 40 years

BACKGROUND: The objectives of this study were to study the probability of local control after breast-conserving therapy (BCT) in a large population of patients with early-stage breast cancer aged < or = 40 years and to determine which factors had prognostic value. METHODS: All patients (n = 758) aged < or = 40 years with clinical stage I or II breast cancer who underwent BCT in general hospitals in the southern part of the Netherlands between 1988 and 2002 were selected for the current analysis. BCT included local excision of the tumor followed by irradiation of the breast. Of 758 patients, 329 patients (43%) received adjuvant systemic treatment, and 36 patients (5%) underwent a microscopically incomplete excision. The median follow-up was 8.5 years. RESULTS: During follow-up, 95 patients developed a local recurrence without evidence of distant disease at the time the recurrence was diagnosed. Contralateral breast cancer was diagnosed in 59 patients. The 5- and 10-year actuarial local recurrence rates were 9.0% (95% confidence interval [95% CI], 6.6-11.4%) and 17.9% (95% CI, 14.1-21.7%), respectively. In a multivariate analysis, adjuvant systemic treatment reduced the risk of local recurrence (hazards ratio [HR], 0.47; 95% CI, 0.28-0.78) and contralateral breast cancer (HR, 0.46; 95% CI, 0.24-0.87) by >50%. CONCLUSIONS: The risk of local recurrence in young patients who underwent BCT was reduced strongly by using adjuvant systemic treatment. This finding may provide an argument if favor of advising the use of systemic treatment for all patients aged < or = 40 years who undergo BCT.     

The roles and controversies of radiation therapy in breast conserving therapy for breast cancer

Breast conserving therapy (BCT) is defined as a combination of conservative surgery for resection of the primary tumor, followed by radiation therapy (RT) for the eradication of residual microscopic disease in the breast. At NIH Consensus Development Conference in 1990, BCT was recognized as the preferred treatment for the majority of women with Stage I and II breast cancer. RT is a potent locoregional treament and its role in BCT in reducing local recurrence is already established. On the other hand, the influence of RT on survival outcome has not yet been closely demonstrated so far. RT appears to be useful as neoadjuvant therapy, and also as exclusive local treatment for patients achieving complete regression (CR) after neoadjuvant chemotherapy. The other possible role of RT is to use it as an alternative to axillary dissection in patients with clinically uninvolved nodes. The question of the appropriateness of using RT in all BCT cases is raised. Since the subgroup of patients who would not deserve any benefit by RT has not yet identified, RT should be delivered as standard treatment following breast conserving surgery for early stage breast cancer.     

New lumps in the breast following conservation treatment for early breast cancer

Summary A new lump in the breast following conservation treatment for early breast cancer may represent a recurrence of the disease or may be a benign lesion. Clinical evaluation of these lumps is often extremely difficult and, potentially, mammography would seem to be of great importance in the assessment. Between November 1981 and March 1986, 214 patients with operable breast cancers of 4 cm or less in diameter underwent conservative treatment. The conservation technique comprised synchronous excision of the primary tumour without a wide margin, axillary clearance, interstitial irradiation with iridium 192 (2000cGy), and subsequent external beam radiotherapy to the breast (4600cGy). After an average followup of 26 months, 17 patients developed a new lump in the treated breast necessitating further biopsy. Seven of these were malignant and 10 benign. In the latter category the most frequent finding was fat necrosis. Clinically, the lesions were indistinguishable from each other. The mammographic signs, which best predicted malignancy, were either of a mass or of a malignant type of microcalcification. This study illustrates the problems associated with deciding the nature of a new lump in the breast following conservation treatment. Mammography is complementary to physical examination, and a base-line mammogram six months after completion of therapy is helpful. Despite the use of mammography, biopsy is the only definitive way of excluding recurrence.     

The impacts of breast conserving treatment and mastectomy on the quality of life in early-stage breast cancer patients

The quality of life (QOL) in 55 early-stage breast cancer patients after surgery was prospectively assessed using a newly developed Japanese QOL questionnaire: The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD). The impacts of breast conserving treatment (BCT) (22 cases) and modified radical mastectomy (MRM) (33 cases) on the QOL in those subjects were compared. The overall QOL scores were evaluated during four periods (before surgery, 0–2, 3–12, and 13–24 months after surgery). The mean scores of the four categories of the QOL-ACD (activity, physical condition, psychological condition, and social relationships) were also compared. The results demonstrated that a significant improvement was observed in the overall QOL scores among the three periods after surgery (0–2, 3–12, and 13–24 months) only in the BCT group (P<0.05). There were no significant differences between the two groups in the overall QOL scores during any of the three periods after surgery, and the mean score of the ‘psychological condition’ during 0–2 months period in the BCT group was significantly lower than that in the MRM group (P< 0.05).     

Cosmetic outcome of breast conserving therapy after sentinel node biopsy versus axillary lymph node dissection

INTRODUCTION: Next to locoregional control, good cosmetic outcome is one of the main goals of breast conserving treatment (BCT) for breast cancer surgery. Factors affecting cosmetic outcome are well known. The sentinel node (SN) procedure avoids lymphedema in the breast, which might influence cosmetic outcome. The aim of this study was to evaluate the cosmetic outcome of BCT after the SN procedure compared to that after axillary lymph node dissection (ALND).METHODS: The subjects were 20 patients who underwent ALND and 20 patients who underwent the SN procedure. After a minimum follow-up period of 43 months, we photographed each patient. Fifteen healthy women served as control subjects. We used the percentage breast retraction assessment index (pBRA=BRA/reference length x 100) to compare cosmetic outcome.RESULTS: The median pBRAs of the ALND group and SN group (14.3 and 6.71, respectively) significantly differed ( p=0.001). The pBRA of the SN group was comparable to the pBRA (6.1) of the control group ( p=0.317).CONCLUSION: Cosmetic outcome of BCT after the SN procedure was superior compared to the cosmetic outcome after ALND. This is an important additional reason to implement the SN procedure in routine daily practice.     

Primary breast cancer therapy in six regions of Germany

Studies from six regions of Germany (Aachen (W1), Dresden (E1), Jena (E2), Marburg (W2), Munich (W3), and Stuttgart (C1)) have been compared to verify and assess the quality of healthcare using breast cancer as an example. All of the data collection was carried out in comprehensive cancer centres and is population-based, with the exception of C1. Classic prognostic factors and the initial treatment of 8661 women with breast cancer, diagnosed between 1996 and 1998, were examined. Primary therapy, breast conserving therapy (BCT), and the use of subsequent local radiation and/or systemic therapy (chemotherapy or hormonal therapy) were analysed. BCT was performed on 39.3-57.7% of patients. By pT-category, the proportion of BCT in the six regions were as follows: for pTis between 37.8 and 64.3%, for pT1 between 51.7 and 71.5%, for pT2 between 25.9 and 51.1%, for pT3 between 0 and 13.1% and for pT4 between 0 and 15.2%. Multivariate analyses, adjusted for age and biological factors, showed a significant influence of the treating hospital on the mastectomy rate. The use of radiotherapy after BCT (80%) was quite homogeneous in the six regions. The application of radiotherapy after mastectomy, however, varied between 10.4 and 32.2%. In all regions, for premenopausal patients, the use of adjuvant systemic therapy almost reflected the St. Gallen-Consensus recommendations. In contrast, post-menopausal women with positive lymph nodes were not always treated according to these standards. In all regions, age had an influence on the administration of treatment: elderly breast cancer patients received less BCT, less radiotherapy and less adjuvant therapy than recommended in the St. Gallen-Consensus. Feedback of the results was made available to each hospital, providing a comparative summary of patient care that could be used by the participating hospitals for self-assessment and quality-control.
