患者56岁,乳腺穿刺诊断查到癌细胞,化疗几个疗程后做手术,手术后标本未找到肿物
病理报告:乳腺癌化疗后反应。
是否化疗能把肿物消除?穿刺诊断是否可以直接发?
请各位老师指点
以下是引用fyshan在2008-9-20 21:47:00的发言:
We have recently 2 cases with similar story, core biopsy dx was DCIS and lumpectomy found no cancer. Our approach was: multiple deeper sections to looking for scar or biopsy site granulation to make sure we got correct tissue/site, if not found, turned the block around (flip over) and cut again. One case we did not find anything, multiple communication with surgeon and make sure he understand the situation. 2nd case, DCIS was found after flipped over the block. Breast lesion here is a big deal, and complecated issue. First time biopsy usually (perfer tissue rather than cytology) left a small metal marker inside the biopsy site for future locatoin under X-ray. lumpectomy specimen comes to us with X-ray film showing the marker and lesion. For your case, it certainly chemotherapy may kill (cure) the cancer, congradulations. |
我不会看细胞学,但可以帮你们翻译这段话,我认为这段话对我们来说还是有启发的,翻译不妥之处,敬请大家批评指正:
我最近遇到2例同样情形的病例,粗针活检诊断DCIS,但肿块切除术后标本中未找到癌。我们的做法是多次深切寻找疤痕或活检部位的肉芽组织,以确定我们所获得的组织是否为我们所需要的组织或活检部位是否正确。如果没有找到,那调整包埋方向再切。
一例没有找到病变,经过多次与临床医师沟通,使他终于明白有这种情况发生,第二例在更换包埋方向后找到了DCIS。
现在乳腺病变是一个很复杂的问题,第一次活检(最好是组织而不是细胞学)通常在活检部位留下一个小的金属标记,以便将来X下定位。肿块切除标本送给我们常有X光片,从X光片中可以看到金属标记物和病变。
对于你的病例,应该确信是化疗杀死了癌细胞,值得庆贺。

I think this case raised a few important questions. 1) I may not understand the fully what it means when we say 乳腺癌, does it include ductal carcinoma in situ? or only invasive carcinoma. I don't practice cytopathology, I thought that cytology alone cannot reliably differentiate DCIS from invasive carcinoma. We will need core or excisional biopsy to make the diagnosis of invasive carcinoma. 2) Chemotherapy (exclude tomoxifen or other hormone therapy) is not a part of therapy for DCIS or low risk stage I invasive carcinoma; DCIS and low risk stage I (<1cm, low grade, ER positive) invasive breast carcinoma are treated by breast conserving surgery (or mastectomy) with or with radiation or tamoxifen. 3) Can we detect the ER and PR status by breast cytology? I would appreciate to hear from expert cytopathologist or breast pathologist from China or US. Thanks.
