Fine needle aspiration cytology in primary breast angiosarcoma: a case report.

Background: Angiosarcoma of the breast is an uncommon, aggressive, vascular tumor. The cytomorphologic features of angiosarcomas have rarely been reported.

Case: The present study describes a case of breast angiosarcoma initially diagnosed by fine needle aspiration cytology.

Cell-free DNA and RNA in plasma as a new molecular marker for prostate and breast cancer.

In this study, we examined several molecular markers in prostate and breast cancer patients and in normal individuals. The markers tested were: variations in the quantity of plasma DNA, glutathione-S-transferase P1 gene (GSTP1), Ras association domain family 1A (RASSF1A), and ataxia telangiectasia mutated (ATM) methylation status in plasma, carcinoembryonic antigen (CEA) and prostate-specific membrane antigen (PSMA) mRNA in peripheral blood mononuclear cells (PBMC) and plasma samples from prostate cancer patients. DNA quantification in plasma was performed using real-time PCR (RT-PCR).

Cell-free DNA and RNA in plasma as a new molecular marker for prostate cancer.

Extracellular nucleic acids could serve as molecular markers in the early detection of cancer and in the prediction of disease outcome. In this study we examined six molecular markers, such as: variations in the quantity of DNA in plasma, glutathione-S-transferase P1 (GSTP1) gene methylation status in plasma, carcinoembryonic antigen (CEA) and prostate-specific membrane antigen (PSMA) mRNA in peripheral blood mononuclear cells (PBMC), and plasma samples from prostate cancer patients in different stages. The combination of DNA load and GSTP1 promoter methylation status identified 83% (10/12) of the prostate cancer patients before therapy.

Evidence for in vivo synergism between docetaxel and gemcitabine in patients with metastatic breast cancer.

Background: The docetaxel and gemcitabine combination is active as salvage therapy in taxane-resistant/refractory patients with metastatic breast cancer (MBC). We conducted a phase II study to determine if this activity is due to an in vivo synergistic effect.

Patients And Methods: Women with measurable MBC, who were refractory or resistant to docetaxel monotherapy as first- or second-line treatment, were enrolled.

Treatment of operable breast cancer in the elderly: a randomised clinical trial EORTC 10850 comparing modified radical mastectomy with tumorectomy plus tamoxifen.

We have examined the outcome of older patients with operable breast cancer treated in a randomised trial by either standard surgery or less extensive surgery and tamoxifen. There were 236 participants aged >/=70 years, randomised to either modified radical mastectomy MRM (n=120) or wide local excision (WLE) and tamoxifen (T) 20 mg daily (n=116). Survival curves were estimated using the Kaplan-Meier method and multivariate analyses were performed using Cox's proportional hazards model.

Tamoxifen associated uterine pathology in breast cancer patients with abnormal bleeding.

The purpose of this study was to evaluate the underlying pathology in breast cancer patients treated with tamoxifen who present with abnormal bleeding. A total of 56 cases were studied and the histopathologic features of 50 curettage and 18 laparotomy specimens were reviewed. All patients were under tamoxifen treatment (10-40 mg daily) for a period ranging from 5 months to 15 years.

Monocyte disorders associated with T cell defects in patients with solid tumors.

T cells proliferate in response to autologous monocytes in the autologous mixed lymphocyte reaction (AMLR). AMLR was found to be impaired in patients with advanced cancer (stages III and IV), whereas normal values were found in the early stages of the disease (stages I and II). Peripheral T lymphocytes from patients with advanced stages also exhibited a decreased ability to produce Interleukin-2 (IL-2) during an AMLR response, whereas production of IL-2 by T cells in stages I and II was comparable to that of normal donors.

Adjuvant androgen treatment of operable breast cancer--a 20 year analysis.

One hundred and fifty-five patients with carcinoma of the breast treated by mastectomy were randomised to receive no additional treatment or to receive adjuvant testosterone. After a minimum follow up of 15 years there is no difference in either relapse free survival or overall survival between the treated and control groups. Stratification by pathological nodal status showed no benefit either for those with negative or positive axillary lymph node involvement.

Sensory changes after treatment of operable breast cancer.

A study has been conducted to compare the nature and severity of post-operative sensory changes (sensory loss, paraesthesiae, and pain) among patients with breast cancer treated by either modified radical mastectomy or a conservative procedure (tumourectomy, axillary clearance, iridium implant, and external radiotherapy). There was a similar incidence of post-operative sensory loss in the two groups, reported by 82% of the mastectomy group and 77% of the iridium group, and an equivalent rate of improvement (76 and 80% respectively). Post-operative paraesthesiae occurred in 61% of the mastectomy group and 63% of the iridium group; maximum severity of paraesthesiae was similar as was the percentage improving.
