Analysis of 6 cases of stromal sarcoma of the breast

OBJECTIVE To investigate the clinical and pathological characteristics, diagnosis and treatment of stromal sarcoma of the breast （SSB）. Methods： The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed.
METHODS The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed.
RESULTS All patients were female and one was menopausal. The median age of the patients was 39 years old （range, 20-55）. All cases had a history of a palpable mass. The tumor rapidly augmented in a short time period in 3 patients. One patient had discontinuous pain and 3 patients had masses located in the upper outer quadrant of the breast. The median tumor radius was 6.0 cm （range, 3-15 cm）. According to the AJCC breast cancer staging standard （6th edition）, 1 case was of stage ⅡA, 2 cases were of stage ⅡB, 2 cases were of stage ⅢB and one case couldn＇t be staged. Four patients were initially treated by excising the tumor and then undergoing mastectomy or modified radical mastectomy after recurrence. Radical mastectomy was suitable for those with pectoralis major muscle involvement. Two patients received simple mastectom）~ 2 patients underwent radical mastectomy and another 2 patients received modified radical mastectomy. After surgery, all patients were identified as SSB through pathology, with focal ossification in one case and mucinous degeneration in another one case. Four patients who underwent axillary lymph node dissection did not have lymph node metastases. Three patients received chemotherapy after surgery. After a median follow-up time of 36.5 months （8-204 months）, 4 patients had recurrence after local excision and 3 patients had recurrence more than 2 times with a median time to recurrence of 2.5 months （1 to 4 months） after surgery. One patient had lung metastases at 7 months after the initial surgery and the other 5 patients were alive without disease at the end of the follow-up period.
CONCLUSION SSB is difficult to diagnose preoperatively and is characterized by its tendency to .recur locally. To obtain negative margins, wide local excision or mastectomy must be performed. Axillary lymph node dissection is not mandatory. The roles of adjuvant chemotherapy and radiotherapy have still been controversial.     

Presentation of Axillary Metastases from Occult Breast Carcinoma

Axillary presentation from occult breast cancer is uncommon and continues to be a diagnostic and therapeutic challenge to physicians. Once the diagnosis of adenocarcinoma metastatic to an axillary lymph node has been confi rmed, a preoperative workup should be done. The current experience is based on several relatively small retrospective reviews and case reports. It is diffi cult to determine the best management of occult breast cancer. However, treatment of axillary lymph node dissection is recommended for local control and complete staging information. Treatment of breast should be a choice between breast conservation with whole-breast radiotherapy and mastectomy. Adjuvant systemic treatment should be offered.     

Operable Breast Cancer： a Clinical Analysis of 6,263 Cases

OBJECTIVE In Europe and America breast cancer commonly occurs in women of middle and old age, with a median age of about 57 years. Modified radical mastectomy now called standard radical mastectomy, has taken the place of traditional radical mastectomy. Patients with breast cancer at an early stage commonly receive BCT (breast conservative therapy). The TNM stage (especially the lymph node status) affects the prognosis, and adjuvant therapy can improve survival. In China, only a few reports have been pubIished studying large numbers of breast cancer patients. This study was designed to analyze the clinical features, surgical pattern and treatment outcome of resectable breast cancer, as well as to explore the prognostic factors and the effect of adjuvant therapy, with a goal to improve the level of diagnosis and treatment.METHODS Records of the 6,263 patients with resectable breast cancer who had been admitted into our hospital from June 1964 to June 2003 were analyzed retrospectively.RESULTS Of the 6,263 cases, 98.8% were female. Breast cancer occurred most frequently in patients of ages 40～49 years (41.0%), especially in patients 45～49 years old (25.2%). A breast lump, which occurred in 96.2% of the patients, was the main clinical manifestation. The overall 5- and 10-year survival rates were 75.16% and 40.44%. Of the patients in TNM stages 0-1,Ⅱ, and Ⅲ, the 5-year survival rates were 96.8%, 73.7% and 46.4% respectively and the 10-year survival rates were 78.7%, 64.6% and 33.5% respectively. The 5-, and 10-year survival rates were higher in the lymph node negative group than in the lymph node positive group (80.3% vs. 55.6%, and 59.2% vs. 31.9%, P＜0.01). Since the 1980s there was no significant difference in survival rates of patients who received a radical mastectomy compared to a modified radical mastectomy(P＞0.05). Of the 73 patients who underwent breast conservative therapy, no local recurrence or metastasis occurred during a maximal follow-up of 17 years. Of the patients in stage T2T4, the 5-, and 10-year survival rates were significantly higher in the group treated with adjuvant chemotherapy compared to the non-chemotherapy group (78.2% vs. 60.1%, and 48.9% vs. 30.7%, P＜0.01).CONCLUSION According to our data, breast cancer most frequently occurred in patients of ages 45～49 years. The TNM stage (especially the lymph node status) relates to breast cancer prognosis. The prognosis was worse in patients with positive lymph nodes compared to the patients with negative lymph nodes. The efficacy of a modified radical mastectomy is equal to that of a radical mastectomy, and breast conservative therapy can be applied to patients in an early stage. Adjuvant chemotherapy and endocrine therapy can improve the survival of resectable breast cancer patients.     

Diagnosis and Treatment Experience of 14 Cases of Breast Cancer Associated with Pregnancy or Lactation

Objective： To explore the diagnosis and treatment experience of breast cancer associated with pregnancy or lactation. Methods： From January 1990 to December 2005, 14 cases with breast cancer associated with pregnancy or lactation were analyzed retrospectively （TNM stage Ⅱ, 2 cases; stage Ⅲ, 11 cases; stage Ⅳ, 1 case）. Diagnosis was established by fine needle aspiration biopsy primarily or routine pathological method if necessary. Abortion was used for discontinuation of pregnancy in 1 case with early pregnancy and 1 case with meddle pregnancy. 2 patients with late pregnancy received cesarean section, 10patients of breast cancer associated with lactation received multidisciplinary and-tumor treatment after discontinuation of lactation. Results： Diagnosis was confirmed by fine noodle aspiration biopsy in 9 cases and by secondary routine pathological method in the other 5 cases, 12 cases were followed up, 1 case of stage Ⅳ died of metastasis 5 months after diagnosis. 3-, 5-year survival rates in 10 cases of stage Ⅲ were 66% and 30% respectively. One case remained alive without recurrence for 8 years up to now. Conclusion： A thorough breast examination is necessary at the first antenatal visit physicians should aggressively pursue work-up in women with a palpable breast tass. In the patients during the second and third trimness, the various modalities available for treatment inholding abortion and their risks and beneath modalities available for treatment including abortion and their risks and benefits must be discussed openly with patients and their families.     

Clinical Analysis of 276 Cases of Non-Palpable TO Breast Cancer

OBJECTIVE Discussion of diagnosis, treatment and prognosis of nonpalpable TO breast cancer.METHODS Between 1978 and 1997, 9,980 female patients with operable breast cancer were treated surgically, of which 276 were determined to have TO breast cancer. Most TO breast cancers could be detected promptly with careful examination of presenting symptoms, such as nipple discharge, local thickening of the breast, nipple erosion, nipple retraction and postmenopausal mastalgia, while 12 cases were detected by routine mammography of the contralateral breast.RESULTS All patients were treated surgically and their tissue subjected to histopathological examination. Most cases (73.0%) were noninvasive or early invasive carcinoma. Axillary lymph nodes metastases were found in 7.69% of 234 mastectomy cases.CONCLUSION The survival rate was significantly increased if the tumor was in an early stage. The 5-, 10-, 15-years survival rates were 98.1%,94.6% and 90.3%, respectively.     

腋窝淋巴结超声造影预测乳腺癌新辅助化疗的疗效

Objective To explore the predictive value of response to neoadjuvant chemotherapy(NAC)in local advanced breast cancer with contrast-enhanced ultrasound(CEUS)of axillary lymph node.Methods CEUS of metastatic axillary lymph nodes in 58 patients stacng Ⅱ-Ⅲ breast cancer was performed before and after NAC treatment. The enhancement patterns and parameters of time-intensity curve were assessed and compared with the pathology.Results The clinic response evaluation were drug-effective in 35 cases and no change in 23 ones.There Were no significant differences in enhancement patterns between no-change and drugeffective groups.Lymph node cortex arriving time was longer in drug-effective cases than that in no-change ones after NAC,whereas it showed no significant differences before NAC.Statistical significant difierence in enhancement duration(ED)was found between the two groups before NAC,which decreased markedly in drug-effective case8 after NAC.Histopatholngic response could be predicted with a sensitivity of 77% and a specificity of 90% by standardized ED below 275 seconds after NAC.No significant difference was found in time to peak(TP),peak intensity(PI)between the two groups.Conclusion The perfusion pattern of axillary lymph node CEUS after NAC Was insufficient to predict curative effect.But the lymph node cortex arriving time and enhancement duration may be of value in the prediction of clinical response to chemotherapy.     

前哨淋巴结活检在乳腺癌中的应用

Objective： To discuss if the sentinel lymph node （SLN） biopsy is able to reflect the status of the axillary lymph node and the application of this technic in clinic. Methods： Using^ 99mTc-signed dextran, SLN-biopsy （SLNB） was carried out in 182 cases with breast cancer during May 1999 to September 2006. During the operation, y-detector was used for orientation. After the SLNB, a modified radical mastectomy or breast conserving surgery were carried out to the patients, then a particular separate pathological examination of the SLN was made. Results： 178 cases of SLNB were carried out successfully, and the success rate was 97.8%, the out-checked SLN of each case ranged from 1 to 4, with an average of 2.5. All SLN was located at the first level of axilla, sensitivity of the SLN B was 93.4%, specificity was 100%, false negative rate was 6.6%, false positive rate was 0, accuracy was 97.8%, positive predictive value was 100.0%, negative predictive value was 96.7%, and Youden＇s index was 0.934. Immunohistochemical examination was carried out in 59 cases of SLN, and 14 cases showed the existences of micro-metastasis, however, metastasis had not been found in non-SLN of these cases. Conclusion： SLN is able to reflect the metastasis of the axillary lymph node, and this can suggest the necessity of the axillary dissection in clinic. The SLNB using the isotope-tracer technic is simple and accurate.

BREAST CONSERVING THERAPY IN STAGE T1 ＆ T2 BREAST CANCER PATIENTS

Objective: To investigate the effect of breast-conservation therapy in early stage breast cancer. Methods: A total of 234 early stage breast carcinoma patients received breast conserving treatment in our hospital. After the operation, they underwent adjuvant chemotherapy and radiotherapy. All of these patients desired to preserve their breasts. Results: After median follow-up of 29.46 months (range from 3 to 100 months), 3 cases had local relapse and 8 cases had distant metastasis. The overall survival rate of 5 year was 96.7%, and the disease free survival rate of 5 year was 87.85%. Conclusion: For early stage breast carcinoma patients, classic quadrantectomy, axillary dissection and post-operative adjuvant chemotherapy and radiotherapy lead to excellent local control and good survival.

Occult breast cancer: A case report and review of the literature

We report a case of a 44-yar-old woman with occult breast cancer presenting as an axillary mass in whom sonography was able to detecct an involved internal mammary node also, thus helping to establish a diagnosis of breast cancer. The patient underwent extended radical mastectomy, including internal mammary lymphadenectomy. Microscopy of the removed specimen failed to find a primary breast cancer lesion. Metastatic cancer was seen in the palpable axillary node, another resected axillary node and a removed internal mammary node. The estrogen and progesterone receptor analysis of the axillary node were negative. Since occult breast cancer was found highly potential for metastasizing to the infraclavicular or internal mammary nodes, it is reasonable to treat such patients in the same way as those with palpable breast cancer, with adjuvant chemotherapy.     

Outcome after treatment of patients with mammographically occult, magnetic resonance imaging-detected breast cancer presenting with axillary lymphadenopathy

Although magnetic resonance imaging (MRI) for patients with mammographically occult breast cancer with axillary lymphadenopathy has been accepted for staging, treatment outcome data in this patient group is lacking. In this study, 16 patients, median age of 45 years (range, 27-66 years), presented with malignant axillary lymphadenopathy, negative mammograms, negative breast physical examination, and abnormal breast MRI. All 16 patients were found to have >/= 1 suspicious lesions on breast MRI. Ten patients had a solitary enhancing lesion; 1 patient had 2 enhancing lesions; 3 patients had 3 enhancing lesions; 1 patient had a mass lesion and diffuse patchy enhancement in the breast; and 1 patient had regional enhancement but no discrete lesion on MRI. Six patients underwent breast-conservation surgery using MRI-guided wire localization and 10 patients had modified radical mastectomy. Fourteen patients received adjuvant chemotherapy and the remaining 2 patients received neoadjuvant chemotherapy. With a median follow-up of 5 years (range, 1.2-7.6 years), the 5-year actuarial local control was 100%, relapse-free survival was 74%, and overall survival was 87%. Three patients developed distant metastases. Two patients died from distant metastases, and 1 patient is alive with metastatic disease. One patient had a relapse in the contralateral axilla and was treated with paclitaxel and is disease free. Although the patient population is small, the outcome after treatment for this group of patients with a mammographically occult, MRI-detected breast cancer presenting with axillary adenopathy is similar to the expected outcome for patients with breast cancer with positive axillary lymph nodes.     

Prognosis of occult breast carcinoma presenting as isolated axillary nodal metastasis

Axillary metastasis from an occult breast carcinoma is an uncommon presentation and presents a therapeutic dilemma. The objective of this study is to describe the presenting clinical features, management approach and treatment outcomes for occult breast carcinoma. We conducted a retrospective review of patients who presented with axillary nodal metastases from an occult breast carcinoma between 1997 and 2004 at the Roswell Park Cancer Institute; 2,150 patients were diagnosed and treated for breast cancer during this period. After excluding stage I and IV patients, we identified 642 who had disease metastatic to lymph nodes, 10 of these had no primary tumor in the breast despite a thorough evaluation including bilateral mammography and breast ultrasound. Of these, 7 had undergone breast magnetic resonance imaging as well. All patients underwent axillary nodal dissection. The breast was managed with radiotherapy alone in 8 patients, wide local excision with radiation therapy in 1 patient and 1 patient underwent mastectomy. No patient had a recurrence with a median 57 months of follow-up. Breast conservation with radiation therapy alone can be considered as a management option for women with occult breast cancer presenting with axillary nodal metastasis.     

隐性乳腺癌的诊治(附68例报告)

目的：探讨隐性乳腺癌的发病特点、检诊规范和治疗方法.方法：回顾性分析68例隐性乳腺癌临床病理资料和治疗效果.结果：全组均经腋窝淋巴结活检及免疫组化M4G33检测明确诊断,65例行根治术或改良根治术,3例行腋窝肿块切除,术后全部辅助放、化疗,全组5、10年生存率分别为77.9%和58.12%;术后常规病检原发灶检出率33.8%（22/65）,结合全乳腺次连续大切片检查,病理原发灶总检出率达86.2%（56/65）.结论：对女性腋窝肿块同时排除全身其它部位癌转移者应高度考虑隐性乳腺癌,腋窝淋巴结活检和免疫组化M4G3检测对确诊有重要意义;根治术标本宜行全乳腺次连续大切片检查以提高原发癌灶检出率,治疗宜选择根治术或改良根治术并辅助放疗、化疗以及内分泌治疗.     

隐匿性乳腺癌36例诊治分析

Presentation of axillary lymphadenopathy without detectable breast primary (T0 N1b breast cancer): experience at Institut Curie

Between 1960 and 1985, 31 patients presented to Institut Curie with isolated axillary lymphadenopathy, of probable metastatic origin from the breast, but without clinical or radiological evidence of a breast tumor and no other primary tumor. The mean age was 54.6 years (range 39-79 years). Histological diagnosis was obtained by axillary surgery (22 cases), drill biopsy (6 cases), and cytology (3 cases). All slides were reviewed for the present study. Treatment consisted of axillary surgery followed by radiotherapy in 22 patients, radiotherapy followed by axillary surgery in 6 patients, radiotherapy followed by modified radical mastectomy in one patient, and radiotherapy alone in 2 patients. Systemic adjuvant treatment was given to 11/31 patients. The median follow-up was 9 years (range 2-26 years). Eight recurrences have appeared. Four patients recurred in the breast only (mean time to relapse: 112 months, range 63-162 months). The four other patients recurred both in breast and/or axilla (mean time to relapse: 23 months, range 7-46 months). Nine patients have developed distant metastases, of whom three also had locoregional recurrence. Among the 11 patients who had had systemic treatment, 5/11 had recurrence or metastases. The overall 5 and 10 year actuarial survival rates were 76 and 71%, respectively. The metastasis-free 5 and 10 year actuarial survival rates were 73 and 71%, respectively. Axillary metastases without clinical or radiological evidence of a primary breast tumor represents a discrete clinical entity, the prognosis of which appears to be better than that of clinical invasive breast cancer with associated lymph node involvement.(ABSTRACT TRUNCATED AT 250 WORDS)     

Analysis of 6 Cases of Stromal Sarcoma of the Breast
