Article: The incremental value of magnetic resonance imaging for breast surgery planning.
[show abstract] [hide abstract]
ABSTRACT: PURPOSE: The aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning. METHODS: One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical treatment were evaluated prospectively. RESULTS: In 48 (30.0%) of the patients, MRI identified suspicious lesions that were not detected by MMG and USG. The diagnosis by MRI was accurate in 17 (10.6%) of them, while in remaining 31 patients (19.4%) the additional lesions found by MRI and interpreted as malignant were found not to be malignant. The pathological accordance of MRI and MMG compared with USG were 69.3 and 70.0%, respectively, whereas individually, MMG and USG were in accordance with the pathological examination in 52.9 and 67.9% of the cases, respectively. CONCLUSIONS: Assessment of the tumor size, multifocality, multicentricity, and presence of ductal carcinoma in situ by MRI may lead to misinterpretations in the majority of patients. The surgical approach should not be changed based solely on MRI findings. An accurately interpreted MMG combined with USG may be sufficient in most cases.Surgery Today 02/2012; · 1.22 Impact Factor -
Article: Diffusion-weighted imaging of solid or predominantly solid gynaecological adnexial masses: is it useful in the differential diagnosis?
[show abstract] [hide abstract]
ABSTRACT: This study investigated whether diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) values provide specific information that allows the diagnosis of solid or predominantly solid gynaecological adnexial lesions, especially whether they can discriminate benign and malignant lesions. DWI was performed in 37 patients with histologically proven solid or predominantly solid adnexial lesions (22 malignant and 15 benign neoplasms). The lesions in our data set were divided into two groups, all adnexial lesions or lesions of ovarian origin, for evaluation. The areas of the highest signal intensity on DWI (b = 800 s mm(-2)) and the lowest ADC values within the lesions were evaluated. On DWI, high signal intensity was observed more often in malignant than in benign lesions (p<0.0001). There was no significant difference between the ADC values of the malignant and benign lesions in either the adnexial (0.88±0.16 vs 0.84±0.42; p = 0.96) or the ovarian (0.85±0.14 vs 1.05±0.2; p = 0.133) lesions. When signal intensities on DWI were compared, however, malignant lesions had higher values than the benign lesions in both the adnexial (0.69±0.21 vs 0.29±0.13; p<0.0001) and the ovarian lesions (0.75±0.14 vs 0.37±0.24; p = 0.003). On DWI, high signal intensity was observed more frequently with the malignant lesions.The British journal of radiology 11/2010; 84(1003):600-11. · 2.11 Impact Factor -
Article: Axillary sentinel node biopsy after neoadjuvant chemotherapy.
[show abstract] [hide abstract]
ABSTRACT: The role of sentinel lymph node biopsy (SLNB) in patients with locally advanced breast cancer (LABC) with potentially sterilized axillary lymph nodes after neoadjuvant chemotherapy (NAC) remains unclear. Between 2002 and 2008, SLNB with both blue-dye and radioisotope injection was performed in 77 patients with LABC whose cytopathologically confirmed positive axillary node(s) became clinically negative after NAC. Factors associated with SLN identification and false-negative rates, presence of non-sentinel lymph node (non-SLN) metastasis were analyzed retrospectively. SLNB was successful in 92% of the patients. Axillary status was predicted with 90% accuracy and a false-negative rate of 13.7%. Patients with residual tumor size >2 cm had a decreased SLN identification rate (p=0.002). Axillary nodal status before NAC (N2 versus N1) was associated with higher false-negative rates (p=0.04). Positive non-SLN(s) were more frequent in patients with multifocal/multicentric tumors (versus unifocal; p=0.003) and positive lymphovascular invasion (versus negative; p=0.0001). SLN(s) positive patients with pathologic tumor size >2 cm (versus <or=2 cm; p=0.004), positive extra-sentinel lymph node extension (versus negative; p=0.002) were more likely to have metastatic non-SLN(s). SLNB has a high identification rate and modest false-negative rate in LABC patients who became clinically axillary node negative after NAC. Residual tumor size and nodal status before NAC affect SLNB accuracy. Additional involvement of non-SLN(s) increases with the presence of multifocal/multicentric tumors, lymphovascular invasion, residual tumor size >2 cm, and extra-sentinel node extension.European journal of surgical oncology: the journal of the European Society of Surgical Oncology and the British Association of Surgical Oncology 11/2009; 36(1):23-9. · 2.56 Impact Factor -
Article: Cranial imaging spectrum in hypertensive disease of pregnancy.
[show abstract] [hide abstract]
ABSTRACT: To determine cranial imaging findings in patients with severe preeclampsia, eclampsia and HELLP syndrome and the correlation between these findings and neurological symptoms. CT or MRI findings of 120 patients diagnosed with severe preeclampsia, eclampsia and/or HELLP syndrome between January 1998 and December 2005 are presented. Pathological imaging findings were observed in 28.1% (n = 32) of the severe preeclampsia group, in 43.3% (n = 30) of the HELLP group, in 51.35% (n = 27) of the eclampsia group and in 61.9% (n = 21) of the eclampsia + HELLP group and in 45% of all patients. Thirty-five patients had specific pathology defined as ischemic lesions, edema, and perivascular microhemorrhage. Infarcts were found in seven, intracranial hemorrhage in seven, hydrocephaly in two, dural sinus thrombosis in two and a pineal cyst in one patient. Specific lesions were generally located in the posterior parietal and occipital lobes. Five patients died due to intracranial hemorrhage and one patient due to septic shock. A wide imaging spectrum from the ischemic lesion to severe intracranial hemorrhage can be detected in complicated cases of hypertensive diseases of pregnancy. It is essential to perform cranial imaging in patients with symptoms and neurological deficits.Clinical and experimental obstetrics & gynecology 02/2008; 35(3):194-7. · 0.43 Impact Factor -
Article: Predictive factors for local recurrence after breast conservative surgery following
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVES: There is still no consensus on the eligibility criteria for breast conservation after neoadjuvant chemotherapy in patients with breast cancer. The present study investigated the long term outcome in patients with breast conservation following chemotherapy to determine its feasibility. METHODS: Between January 1991 to July 2005, 29 patients with clinical stage 2 or 3 who underwent breast conservative surgery following chemotherapy, were included into the study. RESULTS: The clinical stages before neoadjuvant chemotherapy were as follows: T0 (n=1), T1 (n=1), T2 (n=14), T3 (n=7), and T4 (n=6); and N0 (n=2), N1 (n=9), and N2 (n=17), and N3 (n=1). Out of 4 ipsilateral breast tumor recurrences, 2 local recurrences (7%) were detected in the first 5 years, whereas 4 local recurrences (14%) were detected in the first 10 years. The 5-year and 10-year local recurrence free rates were 91.5% and 75%, and the 5-year and 10-year overall survival rates were 92% and 78%, respectively. The 10-year local recurrence-free survival rate was only found to be higher in patients with T0-2 tumors compared to patients with T3-4 tumors (86%, vs 60%, p=0.078). CONCLUSION: Breast conservation after neoadjuvant chemotherapy seems to be safe in selected patients with locally advanced disease including those with clinical T0-2 tumors before neoadjuvant chemotherapy.Turkish Journal of Oncology. 01/2008;
