Surgical management of single and multiple brain metastases: results of a retrospective study.

BACKGROUND: Advancement in diagnosis and treatment of various cancer entities led to an increasing incidence of brain metastases in the last decades. Surgical excision of single and multiple brain metastases is one of the central treatment options beside radiotherapy, radiosurgery and chemotherapy. To evaluate the benefit of surgery with/without whole-brain radiation therapy (WBRT) in single brain metastases and the influence of image guidance for brain metastases resection, 104 patients were retrospectively evaluated for post-operative outcome. PATIENTS AND METHODS: Between January 1994 and December 1999 150 patients were surgically treated for brain metastases at the Department of Neurosurgery at the Technical University of Dresden. Outcome could be evaluated in 104 patients with respect to special treatment strategies and survival time (69 patients with single and 35 patients with multiple lesions). RESULTS: Most metastases originated from primary lung and breast tumours. Karnofsky performance score improved on average by 10 after surgery. The extent of the extracerebral tumour burden was the main influence on survival time. Patients' age below 70 years was combined with prolonged survival time (median survival time, MST: 4.5 months vs. 7 months). Patients with solitary cerebral metastasis had a MST of 16 months, whereas patients with singular lesions had a MST of 7 and 4 months, depending on the extent of the extracerebral tumour growth. Additional post-operative WBRT with 30 Gy was combined with an increase in MST in patients with single brain metastasis (surgery + WBRT: MST 13 months; surgery only: MST 8 months). In addition, the rate of recurrent cerebral tumour growth was distinctly higher in the non-WBRT group. Neuronavigation did not significantly improve post-operative survival time. In 80% of patients extracerebral tumour growth limited patients' survival. CONCLUSION: Surgery is an initial treatment option in patients with single and multiple brain metastases especially with large tumours (> 3 cm). Post-operative WBRT seems to prolong survival time in patients with single brain metastasis by decreasing local and distant tumour recurrence. Neuronavigational devices permit a targeted approach. Multiple processes can be extirpated in one session without prolonging the hospitalisation time for the patient. However, neuronavigational devices cannot assure complete tumour resection.

Abstract：

Objective To summarize the experience of diagnosis and treatment of occult breast cancer in 44 cases. Methods Clinicopathological data of 44 cases of occult breast cancer initially presenting axillary mass alone treated in our department during Jan 1997 to Dec 2008 were retrospectively analyzed. Results The 44 patients with occult breast cancer accounted for 0.42% of all breast cancer patients admitted to our hospital and institute in the same period. The surgery included radical mastectomy in 16 cases, modified radical mastectomy in 19 cases, axillary clearance in 1 case, and simple axillary node excision in 8 cases. Follow-up, ranging from 12-132 months, was available in 38 cases. Among 32 cases who underwent mastectomy or axillary clearance, 2 cases died of distant metastases and 3 cases were still alive with local recurrence at the time of analysis. In two out of six cases who refused further surgical treatment received mastectomy 16 months and 41 months after the primary diagnosis of occult breast cancer, respectively. Others were alive without evidence of recurrence or metastases at the time of analysis. Conclusions Occult breast cancer should be taken into consideration in cases presenting with axillary metastasis of unknown primary origin. The treatment of occult breast cancer should include modified radical mastectomy/radical mastectomy or breast conserving surgery combined with breast irradiation.     

Two cases of radiofrequency ablation (RFA) therapy for control of liver metastases from breast cancer

We present two cases of liver metastases from breast cancer treated by radiofrequency ablation (RFA) for elongation of life. Case 1: A 50-year-old woman was treated by left mastectomy (stage IIIa) in December 2002. In April 2004, she was treated with a combination therapy of weekly paclitaxel and trastuzumab for multiple liver metastases, left supraclavicular lymph node metastases, and multiple bone metastases. After 16 courses of weekly paclitaxel and trastuzumab, liver metastases decreased significantly in size. Because liver metastases recurred during a continuation of weekly paclitaxel and trastuzumab, we performed RFA and chemotherapy using a hepatic artery infusion of docetaxel for liver metastasis. The aggravation spread to the liver lesion and she died after 20 months from liver metastases. Case 2: A 65-year-old woman was treated by left mastectomy (stage IIA) in 1984, and the distant metastasis was not found through the course after an operation. She was noted with a liver function aberration in another hospital in March 2005. We scanned it, and it was diagnosed as multiple liver and bone metastases from breast cancer. Because she did not hope for an anticancer drug treatment for multiple liver metastases, we performed RFA in May 2005. After the second RFA was performed, she does not show any new lesion to the liver for 10 months.     

Three cases of breast cancer with skin metastasis after mastectomy treated by radiotherapy

We reported three cases of patient with triple negative skin metastasis after mastectomy of breast cancer. All three cases had received radiotherapy for skin metastasis. Radiation therapy was effective for recurrent sites, and could improve patient's QOL. After radiotherapy, 2 patients died due to a distant metastasis. Case 1 was resistant to chemotherapy. Case 2 was no indication of chemotherapy because of dementia metastases. Case 3 was the only one continued chemotherapy. It appears that a further consideration was needed for the timing of radiotherapy to be performed among the treatments of locoregional recurrence and distant metastasis of breast cancer.     

Nonsmall cell lung cancer presenting with synchronous solitary brain metastasis

BACKGROUND: Solitary brain metastases occur in about 50% of patients with brain metastases from nonsmall cell lung cancer (NSCLC). The standard of care is surgical resection of solitary brain metastases, or stereotactic radiosurgery (SRS) plus whole brain radiation therapy (WBRT). However, the optimal treatment for the primary site of newly diagnosed NSCLC with a solitary brain metastasis is not well defined. The goal was to distinguish which patients might benefit from aggressive treatment of their lung primary in patients whose solitary brain metastasis was treated with surgery or SRS. METHODS: The cases of 84 newly diagnosed NSCLC patients presenting with a solitary brain metastasis and treated from December 1993 through June 2004 were retrospectively reviewed at The University of Texas M. D. Anderson Cancer Center. All patients had undergone either craniotomy (n = 53) or SRS (n = 31) for management of the solitary brain metastasis. Forty-four patients received treatment of their primary lung cancer using thoracic radiation therapy (median dose 45 Gy; n = 8), chemotherapy (n = 23), or both (n = 13). RESULTS: The median Karnofsky performance status score was 80 (range, 60-100). Excluding the presence of the brain metastasis, 12 patients had AJCC Stage I primary cancer, 27 had Stage II disease, and 45 had Stage III disease. The median follow-up was 9.7 months (range, 1-86 months). The 1-, 2-, 3-, and 5-year overall survival rates from time of lung cancer diagnosis were 49.8%, 16.3%, 12.7%, and 7.6%, respectively. The median survival times for patients by thoracic stage (I, II, and III) were 25.6, 9.5, and 9.9 months, respectively (P = .006). CONCLUSIONS: By applying American Joint Committee on Cancer staging to only the primary site, the thoracic Stage I patients in our study with solitary brain metastases had a more favorable outcome than would be expected and was comparable to Stage I NSCLC without brain metastases. Aggressive treatment to the lung may be justified for newly diagnosed thoracic Stage I NSCLC patients with a solitary brain metastasis, but not for locally advanced NSCLC patients with a solitary brain metastasis.     

Endometrial Carcinoma with Cerebellar Metastasis: A Case Report and Review of the Literature

Background: Endometrial cancer is the most common malignancy involving the female genital tract in the United States. There is a paucity of reports of brain metastases in this disease, and most of these reports emphasize that this pattern of dissemination is rare. Case: We present a case of a 63-year-old woman who had high-grade endometrial carcinoma treated with surgery and radiotherapy. She had three separate episodes of relapse in the lungs, the first two relapses being treated surgically. Chemotherapy was also administered following surgery for the first relapse. The third pulmonary recurrence was treated with chemotherapy and then consolidated with thoracic radiation. Four years from the date of diagnosis, and a few weeks after completion of thoracic radiotherapy, she had evidence of a solitary cerebellar metastasis. This was treated surgically and followed by whole brain irradiation. She died 6 months after this central nervous system diagnosis with systemic dissemination of her cancer. Conclusion: The existing literature on brain metastases from endometrial cancer is reviewed together with the patterns of spread of endometrial cancer. We call attention to the unusually long course of this patient. Partially successful treatment for metastatic disease may have predisposed eventual development of brain metastases. This occurrence reinforces reports emphasizing their increasing incidence in association with endometrial cancer.     

Two bedridden patients with bone metastases from breast cancer effectively treated with pamidronate therapy

Case 1: A 43-year-old woman underwent mastectomy because of locally advanced breast cancer with multiple bone metastases. She was treated with CMF therapy but developed a compression fracture of a thoracic vertebra after 10 months and received pamidronate therapy. Pamidronate administration relived her back pain after 2 months and she was able to walk again after 3 months. However, she developed a resistance to the treatment, and then refused another treatment. She was found to have hypercalcemia 6 months later and received pamidronate again, but died 9 months after the treatment. Case 2: A 52-year-old woman underwent mastectomy because of breast cancer (T2) and was diagnosed as having multiple bone metastases 24 months after the operation. She could not turn over in bed due to progressing bone pain and received pamidronate therapy with CMF therapy at home 23 months after the diagnosis. After 2 months, pamidronate administration relieved her bone pain and she was free of pain after 4 months. After 5 months, X-rays revealed that lytic lesions showed sclerosis, and the pamidronate therapy was assessed as producing a PR. Pamidronate therapy improved her quality of life and activities of daily living, and she continues to receive it this time as an outpatient. Pamidronate therapy is promising as an effective treatment for bedridden patients with bone metastasis from breast cancer.     

21例乳腺癌术后孤立性肺转移的临床分析及预后

目的:探讨乳腺癌术后孤立肺转移的临床病理特点、治疗方法及预后因素。方法:自1999年1 月～2009年1 月,中国医学科学院肿瘤医院对35例乳腺癌术后孤立肺结节患者进行了手术治疗,对上述患者的临床特点、治疗方式、生存期及预后因素进行了单因素和多因素的分析。结果:乳腺癌手术至发现肺结节的时间为6～177 个月,中位时间48个月。经病理证实,乳腺癌肺转移21例（60.0%）,原发性肺癌8 例（22.9%）,良性病变6 例（17.1%）。 乳腺癌肺转移患者中,术后2、3、5 年的生存率分别为95.2%（20/21）、71.4%（15/21）、19.0%（4/21）。 从肺转移切除术至再次出现病情进展的中位时间（PFS）为32个月（3～73个月）;全组患者生存期为12～103 个月,中位时间43个月。经过单因素分析,影响乳腺癌肺转移术后至病情再次进展（PFS）的因素包括乳腺癌原发肿瘤大小、有无脉管瘤栓以及肺转移术后是否接受化疗（P<0.05）;而原发肿瘤至肺转移的时间（无瘤生存期,DFS）以及肺转移术后是否化疗与肺转移术后生存期（OS）有关（P<0.05）。 但经过多因素分析,上述因素对PFS 无显著关系。结论:乳腺癌术后孤立肺结节的外科治疗具有诊断和治疗的作用,术后全身治疗对提高无进展生存及总生存可能有一定的积极意义。      

A case report of long-term survival after radiotherapy for a solitary brain metastasis from breast cancer

This is the report of a patient with a solitary brain metastasis from breast cancer who survived more than 8 years after the first brain metastasis. The brain metastasis was treated with partial removal followed by 30 Gy/15 fructions of whole brain irradiation plus 20 Gy/10 fructions of local boost irradiation for 5weeks. Brain metastases from breast cancer are usually a sign of rapid systemic tumor progression and long-term survivors are extremely rare. However, this case demonstrated the possibility of long-term survival in rare cases of brain metastases from breast cancer. This suggests a need for aggressive therapy in patients with a solitary brain metastasis.     

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.     

Sternal resection for recurrent breast cancer: a cautionary tale

The occurrence of a solitary sternal metastasis from breast cancer is relatively uncommon, and its treatment is controversial. Most case reports on the role of sternal resection in what is termed a "solitary sternal metastasis" tend to present a rather optimistic outcome.Here, we report the case of a premenopausal woman with axillary lymph node-positive, triple-negative breast cancer treated with mastectomy followed by adjuvant chemotherapy and radiation therapy. She developed a radiologically isolated sternal recurrence 3 years later, which was treated with partial sternectomy. The present case report reviews the use of sternectomy for breast cancer recurrence and highlights the need for thorough clinical and radiologic evaluation to ensure the absence of other systemic disease before extensive surgery is undertaken.     

Brain metastases in soft tissue sarcomas: case report and literature review

Background and purpose: Brain metastasis is a relatively uncommon event in the natural history of soft tissue sarcomas. The increasing use of chemotherapy may have caused a reduction in local relapses as well as distant failures leading to an improvement in survival, thereby allowing metachronous seeding of the brain, a sanctuary site. The purpose of this report is to increase awareness amongst clinicians regarding such a possibility.Patients and methods: A review of the departmental sarcoma database following the presentation of this index case in the clinic.Results and discussion: An adolescent male who had previously been treated with surgery and radiotherapy for a spindle cell sarcoma of the left thigh developed a space-occupying lesion in the brain within 6 months of treatment of the primary tumor. He subsequently underwent resection of the presumed solitary brain metastasis followed by whole brain radiotherapy. On radiation he was detected to have pulmonary metastases too, for which he was offered palliative chemotherapy. The patient died of brain metastasis within 4 months. A review of the departmental sarcoma database, restricted to soft tissue sarcomas purely, maintained prospectively from 2000 till date, could not identify any other such case.Conclusion: Brain metastases from soft tissue sarcomas are rare. Patients with neurological symptoms, however, should be appropriately investigated. Surgical resection of brain metastasis could be considered for solitary brain metastasis in non-eloquent areas. Palliative radiotherapy is appropriate for patients with multiple brain metastases or co-existing extra-cranial disease.     

乳腺纯上皮化生性癌9例观察及文献复习

背景与目的:乳腺化生性癌十分少见。对此,本文旨在探讨乳腺纯上皮化生性癌的病理和临床特征以及治疗。方法:回顾性分析1997-2007年9例在我院治疗的女性乳腺纯上皮化生性癌病例。结果:患者中位年龄50岁(37～78岁),9例均行根治术或改良根治术,病理诊断为梭形细胞化生性癌6例,鳞癌3例。雌激素受体(ER)和/或孕激素受体(PR)阳性者2例。2例淋巴结转移。中位随访时间为25(3～112)个月,术后局部复发1例,远处转移3例,肺转移2例,2例患者死亡,1例带瘤生存。结论:本病以梭形细胞化生性癌多见,可同时表达上皮和间叶组织抗原,但较少表达ER和PR。患者多以无痛性肿块就诊,肿块局切复发率高。腋窝淋巴结转移少见,肺转移多见。手术治疗宜选择单纯乳房切除加前哨淋巴结活检。     

Brain metastases after achieving local pathological complete responses with neoadjuvant chemotherapy

Background  We encountered two patients with inflammatory breast carcinoma who developed symptomatic brain metastases after achieving local pathological complete responses (pCR) with neoadju-vant chemotherapy (NAC). Case presentations  The first patient is a 39-year-old woman (Case 1), who underwent NAC with AC (doxorubicin + cyclophosphamide) followed by weekly paclitaxel. After achieving a clinical CR (cCR), we conducted a modified radical mastectomy. Pathological evaluation confirmed no residual malignant cells within the breast tissue or lymph nodes. However, she developed neurological symptoms from brain metastases one month postoperatively. The second patient is a 44-year-old woman (Case 2). Again, no residual malignant cells were detected within the breast tissue or lymph nodes following NAC, but the patient developed symptomatic brain metastases eight months postoperatively. When primary breast tumors are locally advanced, it may be worthwhile to rule out brain metastases even if pCR is obtained after NAC.     

Intraductal carcinoma of the breast: results of treatment with excisional biopsy and irradiation

Between 1976 and 1983, 40 women with intraductal carcinoma of the breast without invasion underwent excisional biopsy and irradiation as an alternative to mastectomy. The median age was 53 years (range, 28 to 77 years) and the median follow-up time since initiation of radiation was 44 months (range, 14 to 97 months). Twenty-seven patients presented with a palpable mass; in 13 patients the tumor was detected only by mammography. A limited axillary dissection was performed in 13 patients, and all lymph nodes removed were negative. Treatment was administered to the breast and adjacent chest wall to a dose of 4,600 to 5,000 rad, with 26 patients also receiving a boost dose of 1,000 to 2,000 rad to the site of the primary. Four patients have developed a recurrence in the treated breast, at 17, 19, 35, and 63 months after the beginning of radiation therapy. The 5-year actuarial rate of local recurrence is 10%. Three of the recurrences were in those four patients who presented with a nipple discharge and a central primary. In two cases, the recurrence consisted of only intraductal carcinoma; in the other two, both intraductal and invasive cancer were found. All four patients with recurrence underwent mastectomy and are well without evidence of distant metastases at 1, 12, 15, and 15 months since mastectomy. Cosmetic results were excellent. No patient has developed distant metastases. Since the number of patients treated is small and the period of follow-up is short, one must be cautious in the interpretation of these results. Nonetheless, the treatment of intraductal carcinoma of the breast by excision and irradiation appears to give acceptable local control and excellent survival when suitable precautions of patient selection and evaluation are taken.     

Effect of Surgery at Primary and Metastatic Sites in Patients With Stage IV Breast Cancer

BackgroundThere is no clear evidence of a survival benefit of resection of the primary tumor, or distant site resection (metastasectomy) in patients with stage IV breast cancer.Patients and MethodsThis retrospective analysis of stage IV breast cancer using the National Cancer Database. To evaluate variables associated with surgery at the primary site, we used univariate analyses followed by multivariate logistic regression. Consequently, we evaluated the impact of lumpectomy, mastectomy or metastasectomy on survival by conducting multivariate Cox regression survival analyses on the following groups: all stage IV patients; a subset of those with only one metastatic site; and another subset with metastasis to multiple distant sites.ResultsA total of 54,871 stage IV breast cancer patients were included in this analysis. Variables associated with the use of surgery at the primary were: age, race, Charlson/Deyo score, insurance and facility type, involved breast quadrant, receptor status, N stage, extent of metastasis, and year of diagnosis. Survival analysis showed that both lumpectomy (median overall survival [OS], 45 months) and mastectomy (median OS, 44 months) were associated with better OS compared to no surgery (median OS, 22 months). The statistical effect was larger in the subgroup with metastasis to one site, but still significant in the subgroup with multiple metastatic sites. Distant site resection also yielded a survival benefit.ConclusionIn patients with metastasis to only one site, metastasectomy was associated with better OS when that site was the liver, lung, or brain.     

Brain metastases after achieving local pathological complete responses with neoadjuvant chemotherapy.

BACKGROUND: We encountered two patients with inflammatory breast carcinoma who developed symptomatic brain metastases after achieving local pathological complete responses (pCR) with neoadjuvant chemotherapy (NAC). CASE PRESENTATIONS: The first patient is a 39-year-old woman (Case 1), who underwent NAC with AC (doxorubicin + cyclophosphamide)followed by weekly paclitaxel. After achieving a clinical CR (cCR), we conducted a modified radical mastectomy. Pathological evaluation confirmed no residual malignant cells within the breast tissue or lymph nodes. However, she developed neurological symptoms from brain metastases one month postoperatively. The second patient is a 44-year-old woman (Case 2). Again, no residual malignant cells were detected within the breast tissue or lymph nodes following NAC, but the patient developed symptomatic brain metastases eight months postoperatively. When primary breast tumors are locally advanced, it may be worthwhile to rule out brain metastases even if pCR is obtained after NAC.     

Late relapse of small cell lung cancer treated with radiation therapy alone — case report

This report describes an unusual case of a long-term survivor with small cell lung cancer (SCLC), treated with radiation therapy alone having a late relapse with solitary brain metastasis 6.5 years after the initial treatment. He received radiation therapy and died of the brain metastasis 8.5 years after the initial treatment. Autopsy revealed no tumor recurrence at the primary site and no distant metastases except for the brain. The histology of the brain tumor was small cell carcinoma.     

Breast carcinoma with brain metastases: clinical analysis and immunoprofile on tissue microarrays

BackgroundDevelopment of brain metastasis in patients with breast carcinoma correlates with poor outcome. Identification of tumor characteristics associated with breast cancer brain metastases (BCBM) could help identify patients at risk.Patients and methodsWe studied 209 patients with BCBM. We evaluated a panel of proteins relevant to the biology of breast carcinoma on tissue microarrays of 133 primary tumors and 56 BCBM, including paired samples from 43 patients, and correlated the findings with the clinical outcome.ResultsThe median survival after BCBM diagnosis was 19 months (95% confidence interval, 13–23 months). Patients presenting with solitary metastasis had a significantly longer median survival than those with multiple lesions (25 versus 11 months, P ≤ 0.0001). We found no significant discordance in the expression of tested markers, but identified a possible association between the expression of basal cytokeratin CK5/6 in the primary carcinoma and the development of multiple rather than solitary brain metastases.ConclusionsExpression of antigens commonly associated with breast carcinoma does not differ significantly between the primary tumor and the corresponding brain metastases. Although no specific immunoprofile identifies breast carcinomas that develop brain metastases, we observed a possible association between CK5/6 expression in the primary tumor and multiple versus solitary BCBM.     

早期乳腺癌保乳治疗的临床研究分析

目的通过早期乳腺癌保乳治疗和改良根治术的比较,探讨早期乳腺癌保乳治疗后的疗效、美容效果和心理变化等问题。方法对68例早期乳腺癌行保乳治疗(本院手术和放化疗59例,外院手术本院放化疗的9例),并与同期行改良根治术治疗的76例早期乳腺癌行对比研究。保乳治疗的全部病例均为女性,年龄范围为28—62岁,平均年龄44．5岁。按全国乳腺癌协作组标准选择病例。保乳术后常规行全乳腺放疗和瘤床加量。改良根治术患者年龄25—68岁,平均47．6岁。改良根治术后放疗的范围根据肿块大小和淋巴结转移情况决定。采用CAF方案化疗。ER／PR阳性的患者均给予口服三苯氧胺内分泌治疗。对68例保乳治疗和76例改良根治术患者的心理变化、性生活和婚姻稳定情况也进行了通信或问讯调查。结果68例保乳治疗患者无局部复发病例,3例出现远处转移(1例为骨转移,1例为骨、肝、肺多发转移,1例为肺、肝转移)。美容效果良好者91．2％,一般者5．6％,差者2．9％。76例改良根治术病例无局部复发,4例出现远处转移(2例为骨转移,1例为脑转移,1例为多发脏器转移)。两个组的近期疗效差异无统计学意义(XP=0．813)。结论早期乳腺癌保乳治疗的疗效与改良根治术基本相同,美容效果和心理的恢复优于改良根治术,是一种值得推广的治疗方法。
