Tumor Vascularity—A Novel Prognostic Factor in Advanced Cervical Carcinoma
1995
Objective: In the search for the optimal treatment of advanced cervical cancer, the identification of valid prognostic factors obtainable without histopathologic investigation of the entire tumor and the locoregional lymph nodes is of paramount interest. Tumor microvessel density has recently been demonstrated to correlate strongly with disease aggressiveness in breast cancer and other malignancies. Methods: We established a computerized image analysis system to quantify tumor microvascularity by using the closest-individual method, which determines the distribution of distances from random points within the tumor to the closest microvessel (DTCMV). Tumor microvascularity was assessed in pa…
Uterine leiomyoma metastasis as a first sign of breast cancer
1998
Uterine metastases from extragenital cancer are rarely reported in the literature. More frequently, the female genital tract is involved by direct extension from an adjacent pelvic organ. A 37-year-old woman had a myoma of the uterine wall and hypermenorrhea. The mass was laparoscopically enucleated, and frozen section examination was performed because it was macroscopically suspicious for sarcomatoid degeneration. The final diagnosis was metastatic carcinoma in the uterus of probable breast origin.
Cardiopulmonary loading in motocross riding
2007
The present study was designed to examine physiological responses during motocross riding. Nine Finnish A-level motocross riders performed a 15-min ride at a motocross track and a test of maximal oxygen uptake (VO2max) in the laboratory. Cardiopulmonary strain was measured continuously during the ride as well as in the VO2max test. During the ride, mean VO2 was 32 ml x kg(-1) x min(-1) (s = 4), which was 71% (s = 12) of maximum, while ventilation (V(E)) was 73% (s = 15) of its maximum. The relative VO2 and V(E) values during the riding correlated with successful riding performance (r = 0.80, P < 0.01 and r = 0.79, P < 0.01, respectively). Mean heart rate was maintained at 95% (s = 7) of its…
Preoperative assessment of breast cancer: sonography versus MR imaging.
2002
The purposes of our study were to compare the diagnostic value of whole-breast sonography and MR imaging as adjunctive techniques to mammography and to determine whether MR imaging should be used routinely in the preoperative assessment of patients with suspected breast cancer.. One hundred four women (age range, 34-84 years; mean age, 60 years) with findings highly suggestive of malignancy in the breast were examined with mammography, sonography, and dynamic MR imaging before undergoing surgery. All visualized suspicious lesions were correlated histologically. The diagnostic relevance of sonographic and MR imaging findings was compared with the diagnostic value of the findings of clinical …
Impact of lactation stage, gestational age and mode of delivery on breast milk microbiota.
2014
There is an increasing evidence of the immunological role of breast milk (BM) microbiota on infant health. This study aims to analyze several determining factors of milk microbiota. A total of 96 milk samples from 32 healthy mothers (19 preterm vs 13 at term gestations; and 15 vaginal deliveries vs 17 Cesarean sections) were longitudinally collected. Microbiota composition was studied by quantitative PCR and the influence of lactation stage, gestational age and delivery mode was evaluated. Globally, Lactobacillus, Streptococcus and Enterococcus spp. were the predominant bacterial groups. Total bacteria, Bifidobacterium and Enterococcus spp. counts increased throughout the lactation period. …
Outcome Analysis and Rational Management of Enhancing Lesions Incidentally Detected on Contrast-Enhanced MRI of the Breast
2003
The purpose of our study was to assess the prevalence, characteristics, and clinical consequence of incidentally detected enhancing lesions on MRI of the breast. SUBJECTS AND METHODS. MRI of the breast (1.0-T scanner, dynamic gadolinium-enhanced T1-weighted three-dimensional gradient-echo sequence, double breast coil) was performed on 1273 women for different indications. Enhancing incidental lesions were defined as enhancing lesions on MRIs that were not expected from findings on the previous conventional imaging. They were classified in five assessment categories using a scoring system based on morphologic and kinetic enhancement characteristics. Detection of enhancing incidental lesions …
Lymphoscintigraphy with peritumoral injection versus lymphoscintigraphy with subdermal periareolar injection of technetium-labeled human albumin to i…
2014
Background Preoperative lymphoscintigraphy is without doubt a valid method for the detection of the sentinel lymph node (SLN). There has been considerable debate regarding the optimal site for the introduction of the tracer; various sites include peritumoral (PT), periareolar (PA), subdermal, and intradermal injection. Purpose To evaluate retrospectively the lymphoscintigraphic identification rate of peritumoral (PT) injection versus subdermal periareolar (PA) injection in the detection of SLNs in breast cancer. Material and Methods Between October 2002 and December 2011, a cohort of 906 consecutive patients with biopsy proven breast cancer underwent 914 SLN biopsy procedures. A total of 33…
Fluctuation of the left ventricular ejection fraction in patients with HER2-positive early breast cancer treated by 12 months of adjuvant trastuzumab.
2018
Abstract Background Cardiac toxicity with a decrease of the left ventricular ejection fraction (LVEF) is the main side effect induced by trastuzumab. This study reports the fluctuation of LVEF over the 12 months of adjuvant trastuzumab in PHARE trial (NCT00381901). Methods LVEF assessment was performed every 3 months while patients received trastuzumab and after completion of treatment over the first 2 years and then every 6 months afterwards. The fluctuations of LVEF over time were described and a logistic regression model was performed investigating associated factors to LVEF perfect recovery at baseline value. Results A total of 1631 patients who received 12 months of trastuzumab from PH…
Liposomal-encapsulated doxorubicin plus cyclophosphamide as first-line therapy in metastatic breast cancer: a phase II multicentric study
2007
Abstract Background The objective of this study is to evaluate the efficacy and toxicity of the liposome-encapsulated doxorubicin (TLC D-99) plus cyclophosphamide (CTX) as first-line treatment of metastatic breast cancer in light of the potential cardioprotective effect of TLC D-99 as compared with conventional doxorubicin. Materials and methods Sixty-seven patients as defined according Simon's two-stage phase II design were enrolled. They received TLC D-99 at the dosage of 60 mg/m2 plus CTX 600 mg/m2, with cycles repeated every 3 weeks. Cardiac function was assessed by ultrasonography at baseline and every two cycles. Results The principal characteristics of the 67 enrolled patients were a…
