We show that maternal plasma cell-free DNA sequencing for noninvasive prenatal testing also may enable accurate presymptomatic detection of maternal tumors and treatment during pregnancy.
Aims:To investigate the association between tumour characteristics and HER-2/neu by immunohistochemistry in primary operable breast cancer.Methods:The association between HER-2/neu and other clinicopathological factors was evaluated in 1362 consecutive patients with primary breast cancer treated between 2000 and July 2003 in one centre. Microscopic tumour size, tumour grade, lymph node status, patient’s age, oestrogen receptor (ER), progesterone receptor (PR), and joint ER/PR status were evaluated, using the χ2test for univariate analysis and logistic regression for multivariate analysis. The hormone receptors and HER-2/neu were studied immunohistochemically. Using the HER-2/neu DAKO scoring system, scores of 0, 1+, or 2+ were defined as negative and 3+ as positive. Data for DAKO scores 2+/3+ versus 0/1+ are also presented.Results:Hormone receptor negative breast cancers were more often HER-2/neu positive than hormone receptor positive cancers, both for ER (28.7%v6.8%) and PR (19.9%v5.9%). In multivariate analysis, both ER, PR, and tumour grade were independently associated with HER-2/neu. In ER+tumours, HER-2/neu overexpression was significantly lower in PR+than in PR−cases (11.5%v5.4%). HER-2/neu overexpression (2.7%) was lowest in the large subgroup of ER+PR+tumours with low tumour grade (grade 1–2), comprising 46.1% of all patients.Conclusions:ER, PR, and tumour grade are independent predictors for HER-2/neu overexpression in women with primary operable breast cancer. ER and PR are negatively associated with HER-2/neu, whereas tumour grade is positively associated with HER-2/neu. In women with ER+tumours, PR status also affects the likelihood of HER-2/neu expression.
Musculoskeletal pains in breast cancer patients under third generation AIs can be severe, debilitating, and can limit compliance. Characteristic tenosynovial, and in some patients joint changes on US and MRI were observed in this series and have not been reported before.
The objective of this study is to assess the therapeutic importance of surgical castration, adjuvant hormonal treatment and lymphadenectomy in endometrial stromal sarcoma (ESS). A retrospective and multicentric search was performed. Clinicopathologic data were retrieved from cases that were confirmed to be ESS after central pathology review. The protocol was approved by the Ethical Committee. ESS was confirmed histopathologically in 34 women, but follow-up data were available in only 31 women. Surgical treatment (n ¼ 31) included hysterectomy with or without bilateral salpingo-oophorectomy (BSO) in 23 out of 31 (74%) and 8 out of 31 (26%) cases, respectively. Debulking surgery was performed in 6 out of 31 cases (19%). Stage distribution was as follows: 22 stage I, 4 stage III and 5 stage IV. Women with stage I disease recurred in 4 out of 22 (18%) cases. Among stage I women undergoing hormonal treatment with or without BSO, 3 out of 15 (20%) and 1 out of 7 (14%) relapsed, respectively. Among stages III -IV women receiving adjuvant hormonal treatment or not, 1 out of 5 (20%) and 3 out of 4 (75%) relapsed, respectively (differences ¼ 55.0%, 95% CI ¼ À6.8 -81.2%). Kaplan -Meier curves show comparable recurrence rates for stage I disease without adjuvant hormonal treatment when compared to stages III -IV disease treated with surgery and adjuvant hormonal treatment. Furthermore, women taking hormones at diagnosis have a better outcome when compared to women not taking hormonal treatment. Three out of 31 (9%) patients had a systematic lymphadenectomy whereas 3 out of 31 (9%) had a lymph node sampling. In one case, obvious nodal disease was encountered at presentation. Isolated retroperitoneal recurrence occurred in 1 out of 31 (3%) of all cases and in 1 out of 8 (13%) recurrences. This single woman later also developed lung and abdominal metastases. Leaving lymph nodes in situ does not appear to alter the clinical outcome of ESS. Although numbers are low, the retrospective data suggest that the need for surgical castration (BSO) in premenopausal women with early-stage disease should be discussed with the patient on an individual basis. The data support the current practice in some centres to administer adjuvant hormonal treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
