Paget disease of the breast: analysis of 41 patients 总被引:14,自引:0,他引:14
The treatment for the patients with Paget disease of the breast is controversial. This review of its natural history, treatment approach, and clinical outcome will help to formulate treatment. Forty-one patients with a diagnosis of Paget disease of the breast were retrospectively reviewed at Providence Hospital & Medical Centers from 1980 to 1999. Ninety-eight percent of patients had underlying carcinoma (ductal carcinoma in situ and/or invasive ductal cancer). Patients with a palpable mass have a much higher incidence of invasive ductal cancer, positive lymph node, and a worse survival rate. The median length of follow-up was 42 months (range: 6--200 months). Twenty-seven percent of patients (11/41) had conservative operations, including 1 patient with a palpable mass; 10 patients with no palpable mass; and 3 patients with recurrence after conservative operation. Thirty-seven percent of patients received adjuvant therapy. Paget disease of the breast has very high incidence of underlying carcinoma (100% in a palpable mass, 96% in nonpalpable mass). Patients with a palpable mass have a worse survival than do patients with nonpalpable mass. Conservative operation should cautiously be selected even for patients with no palpable mass because of a higher recurrence rate. 相似文献

BACKGROUND: In elderly patients with early breast cancer and a clinically clear axilla, axillary surgery, sentinel lymph node biopsy, and postoperative radiotherapy to the residual breast may not be necessary because of reduced life expectancy, effectiveness of hormone therapy in achieving long-term disease control, and generally favorable biologic behavior of breast cancer in elderly patients. METHODS: The authors followed 354 prospectively recruited women aged > or =70 years who had primary, operable breast cancer and no palpable axillary lymph nodes. All 354 women were treated with conservative surgery and adjuvant tamoxifen and without axillary dissection or postoperative radiotherapy. Women who had resection margins in tumor tissue were excluded. Endpoints were cumulative incidence of axillary disease, cumulative incidence of ipsilateral breast tumor recurrence (IBTR), and breast cancer mortality. RESULTS: After a median follow-up of 15 years (interquartile range, 14-17 years), the crude cumulative incidence was 4.2% (4% in pathologic T1 [pT1] tumors) for axillary disease, 8.3% (7.3% in pT1 tumors) for IBTR, and 17% for breast cancer mortality. Of the 268 patients who died during follow-up, 222 patients (83%) died from causes unrelated to breast cancer. CONCLUSIONS: Elderly patients with early breast cancer and no palpable axillary lymph nodes may be safely treated safety by conservative surgery without axillary dissection and without postoperative radiotherapy, provided that surgical margins are in tumor-free tissue and that hormone therapy is administered. Sentinel lymph node biopsy is also unnecessary because of the low cumulative incidence of axillary disease, and axillary surgery can be reserved for the small proportion of patients who later develop overt axillary disease. 相似文献

From 1981 through 1988, 35 patients with prior augmentation mammoplasty were treated for breast carcinoma. Thirty-two patients had unilateral infiltrating carcinomas; three had noninvasive (in situ) lesions. Thirty-four of 35 (97%) lesions were palpable. One noninvasive cancer was occult, discovered mammographically in the absence of physical findings. Prebiopsy mammography was performed in 29 patients with palpable masses and failed to reveal an abnormality in 12 patients, a false-negative rate of 41%. Fifteen patients were treated with mastectomy; the remaining 20 with breast preservation. Thirty-two patients underwent axillary node dissection; 15 (47%) patients had lymph node metastases. There have been seven (20%) recurrences: one local and six metastatic. Four (11%) patients have died. The median follow-up time is 48 months. Women, previously augmented with silicone gel-filled implants, who develop breast cancer are similar in terms of nodal positivity and prognosis, to nonaugmented breast cancer patients who present with palpable masses. When compared with nonaugmented women whose cancers were found with screening mammography, augmented patients with breast cancer present with a higher percentage of invasive lesion and involved axillary lymph nodes, resulting in a poorer prognosis. 相似文献

In the last two decades, the increasing use of screening mammography with the early detection of breast cancer and the newly gained understanding of the biology and changing therapy of breast cancer, emphasizing systemic therapy and minimizing extensive local surgery, has contributed to the increasing development of minimally invasive techniques for the diagnosis of breast lesions. Minimally invasive techniques provide increased patient comfort, excellent cosmetic result and minimal morbidity They are also responsible for decreased costs and better medical care by allowing an informed discussion of breast cancer therapy and planning of surgery with an emphasis on negative margins and the dissection of the sentinel node. Techniques in use include Fine-Needle Aspiration Cytology, Core-Needle biopsy, Vacuum-Assisted Core biopsy (Mammotome) and Large Core biopsy (ABBI, Site-select). We present a balanced, evidence-based approach to the diagnosis of patients with palpable or mammographic abnormalities. 相似文献

BackgroundThe purpose of this study is to evaluate preoperative predictors of nodal metastases in patients with early-stage, HER2-positive (HER2+) breast cancer.MethodsThe SEER Database was queried to identify women with a first diagnosis of stage I-II (T1-T2) HER2-positive breast cancer treated with upfront surgery in 2018. Multivariable logistic regression was used to identify clinical characteristics independently associated with nodal involvement.ResultsOverall, 3333 women with stage I-II HER2+ breast cancer met inclusion criteria and were included in the study. The median age at diagnosis was 59 years (IQR, 51–69 years). Most patients underwent breast-conserving surgery (60.9%), with a median of 3 (IQR 2–4) axillary lymph nodes removed. On final pathology, 762 (22.9%) of T1-T2 HER2+ patients were node positive; 2.7% pN0[i+], 3.7% pN1mi, 15.1% pN1, and 1.4% pN2. Women less than 40 years and those between 40 and 49 years showed the highest proportion of axillary lymph node metastasis, in 33.7% and 30.7% respectively, and declining with age (p < 0.001). Patients with triple-positive breast cancer had the highest rates of nodal involvement (24.8%), compared to 20.7% ER+/PR-/HER2+ and 19.6% of HER2-enriched patients (p = 0.006). On adjusted analysis, age, biologic subtype, tumour size, and type of surgery remained independent predictors of nodal involvement. On subgroup analysis, women under age 50 with T1c HER2-enriched or triple-positive breast cancer had a 33% and 35% incidence of nodal involvement, which declined with age.ConclusionsThe likelihood of pathologic nodal involvement in early-stage HER2+ breast cancer is contingent on age, ER/PR status, and tumour size. 相似文献

Currently, axillary lymph node dissection is increasingly being replaced by the sentinel node procedure. This method is time-consuming and the full immunohistochemical evaluation is usually only first known postoperatively. This study was designed to evaluate the accuracy of preoperative ultrasound-guided fine needle aspirations (FNAs) for the detection of non-palpable lymph node metastases in primary breast cancer patients. We evaluated the material of 183 ultrasound-guided FNAs of non-palpable axillary lymph nodes of primary breast cancer patients. The cytological results were compared with the final histological diagnosis. Ultrasound-guided FNA detected metastases in 44% (37/85) of histologically node-positive patients, in 20% of the total patient population studied. These pecentages are likely to be higher when women with palpable nodes are included. Cytologically false-negative and false-positive nodes were seen in 28 (15%) and three cases (1.6%), respectively. Interestingly 25% (n=7) of the false-negative nodes, revealed micrometastases on postoperative histology. The sensitivity was 57%, the specificity 96%. We conclude that ultrasound-guided FNA of the axillary lymph nodes is an effective procedure that should be included in the preoperative staging of all primary breast cancer patients. Whether lymph nodes are palpable or not, it will save considerable operating time by selecting those who need a complete axillary lymph node dissection at primary surgery and would save a significant number of sentinel lymph node dissections (SLNDs). 相似文献

As axillary recurrence (AR) after a negative sentinel lymph node biopsy (SLNB) is rare, the prognosis of these patients is unknown. Since treatment paradigms for patients with breast cancer are shifting toward less axillary surgery, the number of ARs might increase. In this study, we evaluated primary and salvage treatment as well as long-term survival of patients diagnosed with an AR. A retrospective analysis of the cancer registry of 16 breast cancer units in the Netherlands was used to identify patients who developed an AR after a negative SLNB performed between 2002 and 2004. Using local hospital records we recorded primary patient-, tumor-, and treatment-characteristics, as well as salvage treatment. We identified 54 patients with an AR, median 30 months (range 3–79) after SLNB. Eighteen patients (33 %) were initially treated with breast conserving therapy, 15 of whom received external beam radiation therapy (EBRT). Thirty-three patients (61 %) did not receive adjuvant systemic treatment. In 45 of the 54 (83 %) patients, a salvage axillary lymph node dissection was performed showing a median of three positive nodes (range 1–24). Nine patients (17 %) were not treated surgically: three were treated with salvage EBRT and six with salvage systemic therapy only. At time of detection of the AR, a total of 7 patients (13 %) had proven distant metastases. After a median follow-up of 47 months (range 3–118), the 5-year “post-recurrence” distant metastasis free survival was 50 % and overall survival was 58 %. Significant negative predictors of survival were negative estrogen receptor (ER) status and receiving adjuvant chemotherapy at initial treatment. AR following a negative SLNB is associated with a 58 % 5-year OS. Prognostic factors are ER? primary tumor and receiving adjuvant chemotherapy as a part of initial treatment, reflecting an aggressive phenotype. Adequate regional and systemic salvage therapy constitute a chance for long-term survival after AR. 相似文献

PURPOSE: The outcome of breast cancer treatment can vary in different geographic and ethnic groups. A multivariate analysis was performed for various prognostic factors in 1022 Indian women with pathologic Stage I-II breast cancer treated between 1980 and 2000 with standard breast-conserving therapy with or without systemic adjuvant therapy. METHODS AND MATERIALS: At a mean follow-up of 53 months, the outcomes studied were local failure, locoregional failure, and distant failure, overall survival (OS), and disease-free survival (DFS). RESULTS: The median pathologic tumor size was 3 cm (range, 1-5 cm), and axillary lymph node metastasis was present in 39% of women. The actuarial 5- and 10-year OS and DFS rate was 87% and 77% and 76% and 68%, respectively. Lymphovascular emboli or invasion (LVI) was the strongest independent adverse factor for all failure and survival (local failure, hazard ratio 2.85; 95% confidence interval, 1.68-4.83; OS; hazard ratio, 2.01, 95% confidence interval, 1.35-2.99). Lymph node metastasis was also an independent adverse factor for local failure, locoregional failure, distant failure, DFS, and OS (hazard ratio, 1.55, 95% confidence interval, 1.04-2.30). Age < or =40 years increased the incidence of local recurrence, and patients with inner quadrant tumors had inferior DFS. The incidence of LVI was significantly greater in women with lymph node metastases than in node-negative women (p < 0.001) and in women with Grade 3 tumors than in those with Grade 1 or 2 tumors (p = 0.001). CONCLUSION: In Indian women, LVI was the strongest independent prognostic factor for OS, DFS, and local recurrence, irrespective of nodal status and systemic adjuvant treatment. Although LVI may not be a contraindication for BCT, as has been proposed by certain groups, it is necessary to define its role in prospective studies in determining local and systemic treatment. 相似文献

PURPOSE: The NIH consensus statement on the management of breast cancer has highlighted the paucity of outcome data in non-Caucasian women. Treatment outcome and factors determining it in a large cohort of ethnic Indian women treated with breast conserving therapy (BCT) at Tata Memorial Hospital are reported here. MATERIALS AND METHODS: During 1980-2000, 1,022 pathological Stage I/II breast cancer patients (median age 43 years) underwent BCT (wide excision, complete axillary clearance, whole breast radiotherapy with 6 MV photons plus tumor bed boost, +/-systemic therapy). Median pathological tumor size was 3 cm (1-5 cm). Axillary node metastases were found in 39% women. Of the 938 patients with IDC, 70% were Grade III and in patients where receptor status was known, 209/625 (33%) were ER positive and 245/591 (41%) were PR positive. RESULTS: The 5- and 10-year actuarial overall survival was 87% and 77% and disease-free survival was 76% and 68%, respectively. Actuarial 5-year local and locoregional control rates were 91% and 87%, respectively. Cosmesis was good or excellent in 78% women. Independent adverse prognostic factors for local recurrence were, age<40 years, axillary node metastasis, lymphovascular invasion (LVI), and adjuvant systemic therapy; for locoregional recurrence-inner quadrant tumor, axillary node metastasis, and LVI; for survival-LVI and axillary node metastasis. CONCLUSION: Compared to Caucasians, these Indian women undergoing BCT were younger, had larger, higher grade, and receptor negative tumors. Comparable local control and survival was obtained by using stringent quality assurance in the diagnostic and therapeutic protocol. BCT, a resource intense treatment is safe for selected and motivated patients undergoing treatment at centers with adequate facilities and expertise even in countries with limited resources. 相似文献

Few data are available on bilateral breast cancer in the screening population. The aim of this study was to determine patient
and tumor characteristics of women with bilateral breast cancer at screening mammography. We included all 350,637 screening
mammography examinations of women participating in a biennial screening program in a southern screening region of the Netherlands
between May 1998 and January 2010. For referred women, all breast imaging reports, biopsy results, and surgery reports during
one year after referral were collected. We compared patient and tumor characteristics of referred women with a diagnosis of
bilateral breast cancer or unilateral breast cancer at workup. Bilateral or unilateral breast cancer had been diagnosed in
respectively 40 (2.2%) and 1766 (97.8%) of 1806 referred women. Women with bilateral or unilateral breast cancer did not differ
significantly in mean age, mammographic breast density, family history of breast cancer, or use of hormone replacement therapy.
Compared with index cancers, contralateral cancers comprised significantly more lobular cancers (P = 0.02). Tumor size, mitotic activity, and estrogen receptor status were comparable for both groups, but contralateral cancers
had a significantly lower risk of lymph node metastases (P = 0.03). Compared to unilateral breast cancer, contralateral malignancies in women with bilateral breast cancer comprised
significantly more lobular cancers (P = 0.004) and lymph node negative cancers (P = 0.01). Contralateral breast cancers detected at screening comprise more lobular cancers and show less nodal involvement
than index cancers or unilateral cancers. No differences are observed with respect to other patient and tumor characteristics. 相似文献

In January 1990 a registry for cases of breast cancer occurring in the Bouches-du-Rhone area was set up in conjunction with a screening programme for women over 50 years of age. The aim of this study was to compare histoprognostic findings of unscreened patients (A) with a palpable lesion, screened patients (B) with or without a palpable lesion and self screened patients (C) registered for clinically occult mammary carcinoma. The histoprognostic criteria studied were: histological type, tumor size, prognostic grade and axillary lymph node involvement. Of the 2,478 surgical procedures registered, 1,125 involved women over 50 years of age including 47% with malignant disease. Only 3.7% of screened patients presented intraductal carcinoma compared with 1.17% to 18.2% of unscreened A or self-screened C patients. The incidence of minimal infiltrating breast cancer smaller than 10 mm varied widely from 17.3% in A patients to 33.7% in B patients and 51.4% in C patients (P < 0.001). The incidence of histoprognostic grade III tumors ranged from 17.9% in A patients to 10% in B patients and 4.3% in C patients (P < 0.007). Lymph node involvement decreases from 41% in A to 28% in B patients and 23% in C patients (P = 0.01). Based on our data, 41.9% of screened patients were in the most favorable prognostic category, ie intraductal carcinoma or infiltrating carcinoma less than 10 mm or grade I and no lymph node involvement, versus only 26.1% of A patients and 60.9% of C patients (P < 0.0001). Information of the incidence, pathology of interval tumors in previously screened women will be evaluated in the future. This first study underscores the necessity for this kind of registry to evaluate the histoprognostic profile year by year of a breast cancer screening campaign. 相似文献

To evaluate the effectiveness and safety of weekly docetaxel/carboplatin as primary systemic therapy (PST) for locally advanced breast cancer, we conducted a phase II study. Forty-four patients with HER2-negative locally advanced or inflammatory breast cancer (IBC) received docetaxel 35 mg/m(2) and carboplatin to an area under the curve of 2 mg/mL/min for 3 of 4 weeks over 16 weeks. After completion of PST, patients had breast surgery and then received 4 cycles of adjuvant cyclophosphamide/doxorubicin, standard radiation therapy, and, for hormone receptorpositive tumors, tamoxifen. The mean tumor size was 9.3 cm (range, 5-24 cm). Thirty-seven patients (85%) had palpable lymph nodes; 13 patients (30%) had matted or fixed nodes (N2). Eight patients had IBC. There were 11 clinical complete responses (25%) and 29 clinical partial responses (66%), resulting in 40 objective responses (91% [95% CI, 78%-96%]). Invasive disease disappeared (pathologic complete response) from the breast and axilla in 6 patients (14% [95% CI, 5%-27%]) and from the axilla in 17 patients (39% [95% CI, 24%-55%]). The only significant adverse hematologic event was grade 3 neutropenia in 4 patients (9%). The most common adverse nonhematologic events were fatigue (84% of patients) and alopecia (84%), which were usually grade 1/2. Weekly docetaxel/carboplatin appears to be active and feasible as PST in patients with large breast tumors. 相似文献

Angiogenic characteristics of circulating and tumoural thrombospondin-1 in breast cancer 总被引:1,自引:0,他引:1

In cancer models, thrombospondin-1 (TSP-1) has been shown to inhibit angiogenesis or promote metastasis by increasing adhesion of malignant cells to endothelium. To determine the role of TSP-1 in breast cancer and breast cancer angiogenesis, we have measured TSP-1 in plasma and tumour cytosols and compared levels to established clinicopathological prognostic parameters and intratumoural microvessel density. TSP-1 was measured, by radioimmunoassay, in plasma (pTSP-1) and tumour cytosols (cTSP-1) of women with early breast cancer (EBC) (n=71). pTSP-1 in EBC was compared to pTSP-1 levels in women with advanced breast cancer (ABC) (n=66), normal controls (n=77) and was correlated with prognostic features and microvessel density (MVD) (measured by CD31 immunostaining). cTSP-1 levels were compared to prognostic features and microvessel density. pTSP-1 in women with EBC (median 484, IQR 344-877 ng/ml) and ABC (median 588, IQR 430-952 ng/ml) were elevated when compared to normal controls (median 21, IQR 175-247) (p<0.001). Women with lymph node metastases (n=35) had higher levels of TSP-1 (median 799 ng/ml, IQR 455-943) than women who were node negative (median 343 ng/ml, IQR 267-514) (n=36) (p<0.05). Levels of pTSP-1 in EBC correlated with MVD (R=0.39, p<0.05). Levels of TSP-1 in tumour cytosols of women with EBC (median 1714, IQR 893-5283 ng/ml) correlated with microvessel density (R=0.46, p<0.01). Circulating levels of TSP-1 appear to be a marker of breast cancer aggressiveness and in breast cancer may have a pro-angiogenic rather than anti-angiogenic role. 相似文献

BACKGROUND:
The authors evaluated the clinical characteristics, natural history, and outcomes of patients who had ≤1 cm, lymph node‐negative, triple‐negative breast cancer (TNBC).METHODS:
After excluding patients who had received neoadjuvant therapy, 1022 patients with TNBC who underwent definitive breast surgery during 1999 to 2006 were identified from an institutional database. In total, 194 who had lymph node‐negative tumors that measured ≤1 cm comprised the study population. Clinical data were abstracted, and survival outcomes were analyzed.RESULTS:
The median follow‐up was 73 months (range, 5‐143 months). The median age at diagnosis was 55.5 years (range, 27‐84 years). Tumor (T) classification was microscopic (T1mic) in 16 patients (8.2%), T1a in 49 patients (25.3%), and T1b in 129 patients (66.5%). Most tumors were poorly differentiated (n = 142; 73%), lacked lymphovascular invasion (n = 170; 87.6%), and were detected by screening (n = 134; 69%). In total, 129 patients (66.5%) underwent breast‐conserving surgery, and 65 patients (33.5%) underwent mastectomy. One hundred thirteen patients (58%) received adjuvant chemotherapy, and 123 patients (63%) received whole‐breast radiation. The patients who received chemotherapy had more adverse clinical and disease features (younger age, T1b tumor, poor tumor grade; all P < .05). Results from testing for the breast cancer (BRCA) susceptibility gene were available for 49 women: 19 women had BRCA1 mutations, 7 women had BRCA2 mutations, and 23 women had no mutations. For the entire group, the 5‐year local recurrence‐free survival rate was 95%, and the 5‐year distant metastasis‐free survival rate was 95%. There was no difference between patients with T1mic/T1a tumors and patients with T1b tumors in the distant recurrence rate (94.5% vs 95.5%, respectively; P = .81) or in the receipt of chemotherapy (95.9% vs 94.5%, respectively; P = .63).CONCLUSIONS:
Excellent 5‐year locoregional and distant control rates were achievable in patients with TNBC who had tumors ≤1.0 cm, 58% of whom received chemotherapy. These results identified a group of patients with TNBC who had favorable outcomes after early detection and multimodality treatment. Cancer 2012. © 2012 American Cancer Society. 相似文献17.

Background The purpose of the present study is to evaluate the usefulness of dye-guided sentinel node biopsy in breast cancer patients
with clinically negative nodes and to clarify the anatomic distribution of sentinel nodes in the axilla.
Methods Sentinel node biopsy was performed in patients with T1 or T2 breast cancer who had clinically negative nodes, using an indocyanin
green dye-guided method. Thereafter, complete axillary dissection was performed. Sentinel node and complete axillary lymph-node
dissection specimens were examined separately, and the incidence of metastases was compared.
Results We identified sentinel nodes in 115 (76.7%) of 150 patients with clinically negative nodes. The mean number of sentinel nodes
was 1.7 (range, one to eight nodes). The mean size of sentinel nodes was 9.0 mm (range, 2.0 to 28.0 mm). Of the 31 patients
who had a tumor-positive sentinel node, 14 (45.2%) patients had only the sentinel node involved. There was concordance on
histological examination between sentinel node and axillary node status in 111 (96.5%) of 115 cases. Of the sentinel nodes
89.1% were located cranially to the intercostobrachial nerve and within 2 cm of the lateral edge of the pectoralis minor muscle.
Conclusions Sentinel node biopsy guided by indocyanin green dye is an easy technique with an acceptable detection rate of sentinel nodes
for breast cancer patients with clinically negative nodes. Most of the sentinel nodes were located near the lateral edge of
the pectoralis minor muscle and cranial to the intercostobrachial nerve. 相似文献

The purpose of the present paper was to evaluate the characteristics and outcomes of male breast cancer patients seen for adjuvant therapy at a single institution. A retrospective review of computerized records in the Departments of Medical and Radiation Oncology at the Royal Prince Alfred Hospital (RPAH) was undertaken. Between 1983 and 1996, 24 men were referred for treatment of breast cancer. Of these, 19 had localized breast cancer, four had metastatic disease and one had ductal carcinoma in situ (DCIS). The median age was 57.5 years (range: 26–78) and median follow- up was 6.2 years (range: 0.6–36). Pathological staging was performed. Survival was assessed using actuarial life table analysis. Of the 19 patients who presented with localized disease, there were 12 T1 , five T2 and two T4 cancers. Eleven patients had axillary lymph node involvement. Ten patients were oestrogen receptor (ER) positive, two patients were ER negative and seven patients had unknown receptor status. All patients underwent surgery. Eleven patients received radiotherapy. The median dose and dose per fraction were 50 Gy and 2 Gy, respectively. Adjuvant systemic therapy was delivered to 10 patients, of whom nine were node-positive. Four patients received chemotherapy alone, three patients received chemotherapy and tamoxifen, and three patients received tamoxifen only. Seven patients relapsed (one local, five distant, one both). Of the two patients with local relapses, one had received radiotherapy. Of the distant failures, four of six patients had no systemic therapy. There were only two node-positive patients who were not given systemic treatment and both relapsed. Median survival in all patients with invasive cancer was 7.5 years, and in those with localized disease it was 7.6 years. The median survival of node-positive patients was 3.8 years. In node-negative patients the median survival had not been reached at a median follow-up of 6.2 years. The majority of patients (12/14) with known receptor status were ER+, a finding that parallels those of other studies. Local control rates were 88% (7/8) in patients who had mastectomy alone and 91% (10/11) in those patients receiving adjuvant radiotherapy. Systemic therapy was found to be beneficial in patients with node-positive disease. Chemotherapy was administered more frequently than hormonal therapy. The median survivals were consistent with those reported in other series. 相似文献

The surgical treatment of breast cancer has been a source of controversy. The controversy arises from the differences in physicians' philosophies regarding the biology of breast carcinoma. Traditionally, surgeons have emphasized the potential therapeutic value of regional lymph node dissection, maintaining that adequate loco-regional treatment is of prime concern in patients with localized tumors. On the other hand, medical oncologists have always stressed the systemic nature of cancer. However, breast cancer is a very heterogeneous disease with an enormous range of different biologic characteristics, and new information is continually becoming available on the natural history of breast cancer. Therefore, we should seek a more rational theory based on the clinical evidence which can explain the biologic characteristics of breast cancer. We have proposed a new spectrum hypothesis as follows: (a)tumor cells traverse lymphatics to lymph nodes by direct extension, and there is an orderly pattern in the early stage of lymph node metastases; (b)regional lymph nodes are able to trap tumor cells but are ineffective or incomplete barriers to tumor cell spread; (c)regional lymph nodes have biologic importance, and a positive lymph node is an indicator of a host-tumor relationship that correlates with the subsequent appearance of distant disease; (d)lymphatic and hematogenous dissemination occur not serially, but in a parallel fashion; (e)many palpable invasive breast cancers are a systemic disease, but non-invasive or minimally invasive breast cancers are likely to be a local disease; (f)early detection and treatment of in-breast cancer improves survival, but variations in regional therapy are unlikely to have a major influence on survival. 相似文献

Meningeal carcinomatosis (MC) occurs in up to 5% of breast cancer patients. Few studies have evaluated prognostic markers
in breast cancer patients with MC. Our aim was to describe the treatment of breast cancer patients with MC, and identify prognostic
factors related to survival. Sixty breast cancer patients that had a diagnosis of MC between January 2003 and December 2009
were included. The median age was 46 years (range 27–76). Most patients had invasive ductal carcinoma (78.3%) and high histological/nuclear
grade (61.7/53.3%). Estrogen and progesterone receptors were positive in 51.7 and 43.3% of patients, respectively, and 15%
were HER-2-positive. Symptoms at presentation were headache, cranial nerve dysfunction, seizures, and intracranial hypertension
signals. Diagnosis was made by CSF cytology in 66.7% of cases and by MRI in 71.7%. Intrathecal (IT) chemotherapy was used
in 68.3% of patients, and 21.6% received a new systemic treatment (chemo- or hormone therapy). Median survival was 3.3 months
(range 0.03–90.4). There was no survival difference according to age, nuclear grade, hormonal and HER-2 status, CSF features,
sites of metastasis, systemic and IT chemotherapy, or radiotherapy. However, histological grade and performance status had
a significant impact on survival in the multivariate analysis. Only four papers have addressed prognostic factors in breast
cancer patients with MC in the last two decades. The results of those reports are discussed here. High histological grade
and poor performance status seem to impact survival of breast cancer patients with MC. Prospective studies are necessary to
clarify the role of IT and systemic treatment in the treatment of those patients. 相似文献
