Metachronous secondary primary occult breast cancer initially presenting with metastases to the contralateral axillary lymph nodes: report of a case

We report a rare case of a 64-year-old female with metachronous secondary primary left occult breast cancer initially presenting right axillary lymph node metastases. The patient, who had received breast-conserving therapy for left breast cancer at another hospital about 4.5 years ago, came to our hospital complaining of right axillary node swelling. After both breast and systemic examination, she received complete right axillary lymph node dissection. Just after the operation, she was diagnosed with right occult breast cancer by a review of the right axillary lymph nodes and previous left breast cancer. She was followed by radiation and systemic chemoendocrine therapies. One year after axillary lymph node dissection, mammography and ultrasonography showed a new lesion in her left breast. Core needle biopsy revealed similar findings to right axillary lymph node metastasis. After salvage surgery, the diagnosis was revised. We recommend that patients without clinical findings except for axillary lymph node metastasis, especially post-breast-conserving surgery followed by radiation therapy, should be considered not only as having ipsilateral but also contralateral occult breast cancer. If there is no evidence of a primary lesion, axillary lymph node dissection needs to be carried out, and the patient should be offered the choice of radiation therapy or mastectomy followed by proper systemic therapy.     

56例隐匿性乳腺癌临床病理特征分析及诊疗策略探讨

背景与目的：隐匿性乳腺癌发病隐匿,诊断困难,治疗策略不确定,是乳腺癌领域的难点和热点。本研究探讨了隐匿性乳腺癌的临床病理特征及诊疗策略。方法：对56例隐匿性乳腺癌患者在术前采用乳腺彩超、钼靶、磁共振及PET/CT检查,对比不同检查方法对隐匿性乳腺癌可疑原发灶检出率及病理符合率的差异。治疗方案采用新辅助化疗、乳腺癌改良根治术、保乳+腋窝淋巴结清扫术、腋窝淋巴结清扫术,术后行化疗+放疗。结果：乳腺超声、X线、MRI、PET/CT对乳腺可疑原发灶的检出率分别为7.14%（4/56）、29.41%（15/51）、37.50%（18/48）和16.28%（7/43）;结合术后病理学检查发现其病理符合率分别为66.67%（2/3）、50.00%（7/14）、50.00%（9/18）和50.00%（3/6）;26例患者乳腺超声、X线及MRI均未发现可疑原发灶,其中21例接受病理学检查,阳性率为14.29%（3/21）;对39例乳腺癌改良根治术标本行乳腺病理切片检查,检出原发灶15例,检出率38.46%。根据St. Gallen指南分子分型标准,Luminal A型、Luminal B型、HER-2阳性型和三阴性型比例分别为7.14%、46.43%、12.50%和33.93%。术后随访52例,随访时间10~104个月,中位时间35个月,复发转移4例,死亡0例。检出原发灶的15例患者中,复发或转移2例;未检出原发灶的24例患者中,无复发或转移;行新辅助化疗17例,达病理学完全缓解（pathological complete response,PCR）2例,复发或转移2例;行乳腺癌改良根治术39例,复发或转移2例;行保乳+腋窝清扫8例,复发或转移2例;腋窝清扫9例,无复发或转移。结论：乳腺MRI检查在隐匿性乳腺癌的排除性诊断中有重要价值;乳腺超声、X线及MRI均未发现可疑原发灶的患者其乳腺病理原发灶检出率较低;隐匿性乳腺癌的治疗策略可选择新辅助化疗、乳腺癌改良根治术、保乳+腋窝清扫术、腋窝清扫术;乳腺病理学未检出原发灶的患者复发转移率低于检出原发灶者。     

核素淋巴显像识别前哨淋巴结在乳腺癌治疗中的应用

目的评价核素淋巴显像和γ探针定位在乳腺癌中确定前哨淋巴结(SLN)的应用价值,验证前哨淋巴结活检替代腋窝淋巴结清除术用于乳腺癌治疗的安全性与价值。方法选择1999年6月至2009年11月本院住院的女性乳腺癌患者206例(体检时腋窝均未扪及肿块),应用99Tcm-DX37～74 MBq或99Tcm-SC74 MBq经皮下注射,行核素淋巴显像后,术中注射专利兰1 ml和(或)术中用γ探针定位并行前哨淋巴结活检,与术中冰冻病理检查结果对照。若术中冰冻发现有前哨淋巴结转移,则行腋窝淋巴结清除术,若前哨淋巴结阴性,则不做腋窝淋巴结清除,术后定期随访。结果 206例乳腺癌术中成功活检SLN204例,成功率为99.0%(204/206)。本组有64例仅行SLN切除,术后病理检查证实64例SLN均阴性,故未行腋窝淋巴结清除,其中仅1例于术后1年时出现腋窝淋巴结转移,其余63例患者在随访期间均未发现腋窝淋巴结转移,也未出现同侧上肢水肿、感觉及活动异常;另140例行腋窝淋巴结清除,其中6例经病理证实SLN阳性但腋窝淋巴结为阴性,134例经病理证实SLN阳性35例,阴性99例,腋窝淋巴结阳性37例,阴性97例。核素淋巴显像和γ探针定位法的灵敏度为94.6%(35/37例),准确率为98.5%(138/140),假阴性为5.4%(2/37)。结论核素淋巴显像和γ探针定位应用于乳腺癌是切实可行和可能的,对预测腋窝淋巴结转移有很大的临床实用价值。如技术方法规范,早期乳腺癌前哨淋巴结活检则能取代常规的腋窝淋巴结清除术,乳腺癌手术上肢并发症的发生率可大大降低。     

Axilläre Lymphknotenmetastasen bei CUP

Women who present with axillary lymph node metastases and no other distant metastases and no evidence of a breast cancer primary represent a potentially curable subset of individuals with CUP. The standard approach is to perform an axillary lymph node dissection followed by adjuvant systemic treatment and radiotherapy according to published guidelines for lymph node positive primary breast cancer. Mastectomy is not mandatory. In most cases occult breast cancer is associated with good prognosis. Reported 5-year survival rates after treatment of an occult primary breast cancer with axillary metastases range from 60–90%.     

Sentinel lymph node biopsy in breast cancer patients: the medical oncology perspective

Recent data indicates that the sentinel lymph node biopsy (SLNB) is a possible alternative to axillary lymph node dissection (ALND) in early breast cancer patients, with minimal risk of complications. From the medical oncologist's point of view, the impact of SLNB on the management of patients should consider if SLNB is useful to choose adjuvant treatment, if it is adequate to provide local control, and what is the significance of lymph node micrometastases on treatment and staging. Lymph node involvement has always been recognised as the most important prognostic factor in early-stage breast cancer, even if many other parameters have been evaluated in recent years. However, the lack of knowledge of nodal status in patients with false-negative SLNB seems to result in an undertreatment in a very low percentage of patients. Adjuvant chemotherapy and hormonal therapy with tamoxifen are associated with an absolute reduction of the risk of recurrence and death both in node-positive and in node-negative patients, then if patients are treated with modern adjuvant systemic therapy, any effect associated with false negative SLN should be minimised. The impact of axillary treatment on survival is still controversial, but in recent times axillary lymph node positivity is considered as an indicator for high risk of systemic diffusion of the disease rather than a possible origin of systemic metastases. The significance of occult sentinel lymph node metastases detected by immunohistochemistry (IHC) or molecular biology on prognosis is still uncertain. The new version of the staging system of breast cancer has recognised the need for a standard diagnostic approach and of a nomenclature system which also takes SLNB into account.     

隐匿性乳腺癌的研究进展

隐匿性乳腺癌是一种罕见的特殊类型乳腺癌,临床上以腋窝淋巴结肿块为首发症状,而乳房肿块难以通过触诊诊断的一种疾病。一直以来,隐匿性乳腺癌的病例较少,临床诊断困难。腋窝淋巴结穿刺后病理检查结合免疫组化及影像学检查,可提高该病的术前诊断。     

A case regarded as an occult breast cancer treated without mastectomy

A 51-year-old woman was admitted to our hospital with a chief complaint of left axillary tumors. No such tumors were detected in bilateral breasts by ultrasonic tomography, mammography, computed tomography, and magnetic resonance imaging. The core needle biopsy from the left axillary lymph node was examined, and the specimen revealed an occult breast cancer, because the microscopic findings resembled the breast cancer organization and immunochemistry revealed positivity of the estrogen receptor. The radical left axillary dissection was operated. Tamoxifen and FEC 100 6 cycles were selected as adjuvant treatment. At one year after operation, she has no recurrence. Carcinoma cells had portedly been recognized in the mammary gland with 82.7% of the cases who had undergone mastectomy for occult breast cancer. However, in many cases, the patient's consent for mastectomy was not obtained like as in this case, and the choice of treatment is often difficult. We considered that the case's accumulation was necessary to verify the possibility of the mastectomy omission to an occult breast cancer, presented the case report.     

Prognostic significance of occult axillary lymph node metastases after chemotherapy‐induced pathologic complete response of cytologically proven axillary lymph node metastases from breast cancer

BACKGROUND:

Primary systemic chemotherapy has been a standard of care for the management of locally advanced breast cancer (LABC) patients and has increasingly been used for patients with large operable breast cancer. Pathologic complete response (pCR) of axillary lymph node metastases predicted an excellent probability of long‐term disease‐free and overall survival. Although the clinical significance of occult lymph node metastases in patients with breast cancer was extensively studied, their prognostic value in patients with LABC after primary chemotherapy was not known. This study evaluated the detection rate and clinical significance of occult lymph node metastases in lymph nodes that contained metastatic carcinoma at the time of initial diagnosis and converted to negative based on routine pathologic examination after primary systemic chemotherapy.

METHODS:

Fifty‐one patients with LABC and cytologically involved axillary lymph nodes that converted to negative after preoperative chemotherapy were identified from 2 prospective clinical trials. All lymph node sections were reviewed, 1 deeper level hematoxylin and eosin‐stained section of each lymph node was obtained and immunohistochemical staining for cytokeratin (CK) was performed. A total of 762 lymph nodes were evaluated for occult metastases. Kaplan‐Meier survival curves were used for calculating disease‐free and overall survival times.

RESULTS:

Occult axillary lymph node metastases were identified in 8 of 51 (16%) patients. In 6 patients, occult metastases were found in only 1 lymph node. In 7 patients, only isolated CK‐positive cells were identified. In all cases, occult carcinoma cells were embedded within areas of fibrosis, foreign body giant cell reaction, and extensive histiocytosis. Patients with occult lymph node metastases tended to have a higher frequency of residual primary breast tumors than those without occult metastases (4 of 8 vs 7 of 43, respectively). There was no statistically significant difference in disease‐free or overall survival times between patients with and without occult metastases after a median follow‐up 63 months.

CONCLUSIONS:

Persistent occult axillary lymph node metastases were not uncommon in patients with axillary lymph node‐positive LABC who experienced a pCR in involved lymph nodes after preoperative chemotherapy. However, such occult metastases did not adversely affect the good prognosis associated with axillary lymph node pCR. Therefore, routine lymph node CK evaluation was not recommended after primary chemotherapy. Cancer 2009. © 2009 American Cancer Society.

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.     

Is It Contralateral Axillary Metastasis or Occult Breast Cancer?: A Confusing Case Report

We report the case of a 43-year-old woman with primary left breast cancer presenting metastatic lymphadenopathy in the contralateral axilla. This patient represents a diagnostic and therapeutic challenge because primary breast cancer, occult contralateral breast cancer, and extra-mammary primary lesion can all be the source of the contralateral axillary metastasis. Left breast-conserving surgery, left sentinel lymph node biopsy, right breast mass excision, and right axillary lymph node dissection were performed. Immunohistochemical analysis revealed that the left breast cancer specimen was positive for estrogen receptor (ER) and progesterone receptor (PR), but negative for human epidermal growth factor receptor 2 (HER2). In contrast, the right axillary lymphadenopathy specimen was negative for ER and PR, but positive for HER2. Further investigation revealed no evidence of occult primary cancers or extra-mammary tumors. After surgical intervention, the patient was treated with adjuvant chemotherapy, adjuvant radiation therapy, and targeted therapy with trastuzumab. Two years after diagnosis, she is free of disease and presently being treated with tamoxifen.Key Words: Breast carcinoma, Occult primary tumor, Contralateral axillary lymph node metastasis, Immunohistochemistry     

Clinical evidence of breast cancer micrometastasis in the era of sentinel node biopsy

Sentinel node biopsy for early-stage breast cancer has been established as an excellent surgical and staging procedure developed to enhance the detection of minimal lymph node involvement such as micrometastases. Multisection and the proper use of immunohistochemical staining have led to the increased detection of micrometastases, and this has given rise to new questions about the treatment to be employed concerning micrometastasis. That is whether complete axillary lymph node dissection (ALND) and adjuvant systemic therapy are really required for patients with micrometastasis because of the low prevalence of nonsentinel lymph node metastasis. Some currently published case studies report that selected patients with micrometastases without further ALND would not suffer from a high incidence of regional recurrence. However, the long-term prognostic risk of systemic recurrence and local failure associated with residual axillary disease in the sentinel lymph node-positive patient electing for no further axillary surgery has not been defined. Numerous studies have investigated the impact of occult metastases, which may be regarded as micrometastases or a small tumor deposit. Although data from randomized controlled trials are lacking, these studies suggest that the prognosis of breast cancer patients with micrometastases should not be considered the same as that in truly node-negative patients. Patients with micrometastases should have some adjuvant systemic therapy. Ongoing randomized trials will provide prospective answers to the question of the optimal treatment for micrometastasis.     

Sentinel lymph node biopsy in breast cancer

The clinical management of breast cancer has improved tremendously in the last 2 decades. Sentinel lymph node biopsy (SNB) allows conservation of the axillary lymph nodes in most patients who have breast cancer. Furthermore, it allows identification of occult nodal disease after step sectioning and more detailed staging. Although large breast tumors, multicentric disease, recurrent cancers, and use of neoadjuvant therapy were previously considered contraindications to SNB, a large body of evidence is accumulating to support its use in these cases. The prognostic significance of micrometastases and isolated tumor cells needs clarification in prospective, randomized trials.

Staging and treatment of clinically occult breast cancer

Five hundred fifty-seven biopsies were performed for clinically occult mammary lesions, detected by mammography as clustered calcifications or nonpalpable masses within the breast. One hundred seventy-five cancers were demonstrated within this group, including 106 invasive carcinomas, 10 microinvasive carcinomas, 45 in situ ductal carcinomas, and 14 lobular carcinomas in situ (lobular neoplasia). No patient with in situ or microinvasive carcinoma had evidence of axillary node metastases in 33 specimens studied. However, a disturbingly high proportion of those patients with invasive carcinomas, approximately 35%, had histologically confirmed axillary node metastases, despite the small size of the primary tumors. These observations suggest that the use of the term "minimal" cancer is misleading when applied to invasive carcinoma. Staging systems for breast cancer have been imprecise when referring to nonpalpable lesions. Cancers detected as clustered calcifications only or as areas of parenchymal distortion without an accompanying mass are properly considered as T-0 cancers, with a suggested T-0(m) to indicate that the lesion was detected by mammography. However, when the mammogram indicates the presence of a mass that proves to be malignant, although the clinical examination may have been negative, the cancer should be staged according to the size of the mass on the mammogram, with the notation that it was detected by mammography, e.g., T-1(m), T-2(m), etc. The incidence of axillary node metastases even in these so-called occult cancers is significant, so that recommendations for treatment for any invasive cancer, regardless of its size, must take these observations into account. Similarly, the incidence of multifocal sites of cancer within the breast, even in the noninvasive cancers encountered, must be remembered when treatment is suggested.     

保留肋间臂神经在乳腺癌腋窝淋巴结清扫术中的应用

目的探讨Ⅰ、Ⅱ期乳腺癌改良根治术中保留肋间臂神经的临床价值。方法65例行Ⅰ、Ⅱ期乳腺癌改良根治术,保留肋间臂神经50例,切除15例,术后对患者进行随访观察。结果保留肋间臂神经50例中,术后患者上臂内侧及腋部皮肤感觉正常46例（92.0%）,感觉异常4例（8.0%）;切断肋间臂神经15例均有感觉障碍,两组比较差异有显著性（χ2=12.42,P〈0.001）。随访1年,50例均无肿瘤局部复发。结论在乳腺癌腋窝淋巴结清扫术中,保留肋间臂神经对改善患者术后生活质量具有一定的临床价值。     

乳腺癌淋巴结转移规律对术后放射治疗设野的影响

目的 探讨乳腺癌淋巴结转移规律和乳腺癌根治术后放射治疗的适应证及照射范围。方法 行选择性胸膜外式乳腺癌扩大根治术78例,分析其中资料完整的61例,探讨内乳淋巴结的转移情况。非选择性乳腺癌根治术 锁骨上淋巴结清扫术46例,术前检查锁骨上淋巴结均为阴性,将锁骨上淋巴结及腑窝淋巴结分别标记为S及L1、L2、L3送检。行乳腺癌根治术412例,标记出L1、L2、L3淋巴结分别送检,用以分析腋窝淋巴结跳跃式转移的规律。结果 内乳淋巴结总的转移率为24.6%,其中腋窝淋巴结转移者,内乳淋巴结转移率为36.7%,而腋窝淋巴结无转移者,内乳淋巴结转移率为12.9%,转移部位仅限于1、2、3肋间。锁骨上淋巴结跳跃式转移率为3.8%;腋窝淋巴结的跳跃式转移率为8.1%。结论 乳腺癌淋巴结转移有其内在规律,乳腺癌根治术后照射野可以依据其区域淋巴结的转移规律进行修改,照射内乳区淋巴结时可以不必常规包括4、5肋间。当腋窝淋巴结仅有L1、L2组转移而无L3组转移时,锁骨上淋巴结区也可以不予照射。     

53例早期乳腺癌保乳治疗临床分析

目的探讨早期乳腺癌保乳治疗的手术处理方法及近期疗效。方法 2005年6月至2009年10月共收治女性乳腺癌患者276例,对其中Ⅰ~Ⅱ期原发乳腺癌施行保乳手术治疗,手术方式采用乳腺局部肿物扩大切除加同侧腋窝淋巴结清扫术或同侧前哨腋窝淋巴结活检术,术中对肿物进行切缘冰冻快速病理检查,术后患侧乳房接受放射治疗。结果 53例患者成功实施了保乳手术,手术后随访6个月,对保留乳房治疗的满意率达99%,十分满意占90%,与腋窝前哨淋巴结活检术结合进一步降低了患侧上肢淋巴水肿等并发症的发生,提高了患者的生活质量。经随访2~52个月,中位随访17个月,无乳腺局部复发病例,无远处转移及死亡病例。结论Ⅰ~Ⅱ期乳腺癌保乳治疗近期疗效满意,相关手术的处理方法可行,远期疗效有待长期随访观察。
