Laparoscopic sentinel lymph node mapping and excision of the rectum using a radioactive tracer — a prospective experimental study

2009

Introduction: Patients with a low risk T1 rectal carcinoma can undergo the therapy of a local excision. In these patients the lymph node status remains unknown. There is a potential risk of up to 7% for nodal metastasis, in high risk cases it can rise up to 35%. To investigate the possibility of using the Sentinel lymph node (SLN) concept, which is anchored in the therapy of malignant melanoma and breast cancer, an experimental study on pigs was undertaken. The objective of the study was to laparoscopically identify and extract SLN’s from the rectum using a radioactive tracer (RT). Material und Methods: The experiment was conducted upon 30 pigs, because sample size calculation indicated tha…

Nachsorge des Mammakarzinoms

1994

7865 follow-up examinations were performed on 420 patients who had had surgery for carcinoma of the breast; there were 2755 radiographs of the chest, 2660 sonographic examinations of the upper abdomen and 2450 contralateral mammograms. The most common findings were metastases seen on the chest radiographs during the 13-24 and 25-60 months intervals in 4.7% of cases. The incidence increased with initially higher tumour stages and in ductal carcinomas. Sonography of the upper abdomen showed 4.3% of liver involvement, mostly between the second and fifth year; this was independent of tumour stage or the histology of the primary tumour. Positive mammography of the contralateral breast was found …

Peut-on proposer un prélèvement du ganglion sentinelle en cas de chimiothérapie néoadjuvante dans les cancers du sein et à quel moment ?

2016

The main goal of preoperative chemotherapy is to reduce the size of the tumor and allow conservative treatment. Neoadjuvant treatment can affect axillary status with a downstaging in one third of the cases. For these patients, the benefit of axillary node dissection is questioned and the sentinel node biopsy (SLNB) seems to be a relevant option. However, the timing of performing SLNB is still debated especially for clinical negative patients with negative axillary ultrasound before preoperative chemotherapy. For axillary positive nodes proved by biopsy/cytology before preoperative chemotherapy, SLNB can be an option if there is a good clinical and radiological response.

Assessment of Quality of Life in Postmenopausal Women with Early Breast Cancer Participating in the PACT Trial: The Impact of Additional Patient Info…

2019

<b><i>Background:</i></b> Breast cancer patients’ self-understanding of their disease can impact their quality of life (QoL); the relationship between compliance and QoL is poorly understood. <b><i>Patients and Methods:</i></b> The Patient’s Anastrozole Compliance to Therapy (PACT) program, a prospective, randomized study, investigated the effect of additional patient information material (IM) packages on compliance with adjuvant aromatase inhibitor (AI) therapy in postmenopausal women with hormone receptor-positive early breast cancer. The QoL subanalysis presented here examined the impact of IM packages on QoL and the association between QoL…

Wood-derived estrogens: studies in vitro with breast cancer cell lines and in vivo in trout.

1996

The wood-derived compound, beta-sitosterol (purity > 90%), was shown to be estrogenic in fish. It induced the expression of the vitellogenin gene in the liver of juvenile and methyltestosterone-treated rainbow trout. Structural similarities to beta-sitosterol notwithstanding, cholesterol, citrostadienol, beta-sitostanol, and 5-androstene-3 beta,17 beta-diol, an estrogenic member of the androstenic steroid group, were inactive. An abietic acid mixture (37% abietic acid, 6% dehydroabietic acid, and a remainder of unknown compounds) showed slight hormonal activity in feed, but it was completely inactive when given intraperitoneally in implants. The estrogenic component of the abietic acid prep…

Association between cognitive impairment and guideline adherence for application of chemotherapy in older patients with breast cancer: Results from t…

2018

Background This study examined the association between cognitive impairment and guideline adherence for application of chemotherapy in older patients with breast cancer. Patients and methods In the prospective multicenter cohort study BRENDA II, patients aged ≥65 years with primary breast cancer were sampled over a period of 4 years (2009-2012). A multiprofessional team (tumor board) discussed recommendation for adjuvant chemotherapy according to the German S3 guideline. Cognitive impairment was screened by the clock-drawing test (CDT) prior to adjuvant treatment. Results Two hundred and sixty-three patients were included in the study and CDT data were available for 193 patients. Thirty-one…

Vitamin D levels in Mediterranean breast cancer patients compared with those in healthy women

2018

To evaluate the vitamin D status of postmenopausal women with early estrogen-receptor-positive breast cancer and to compare it with that of healthy postmenopausal women from the same Mediterranean region. STUDY DESIGN AND OUTCOME MEASURES: Data from 691 breast cancer (BC) patients in the B-ABLE cohort were analyzed after recent cancer intervention (recent-BC) or after a minimum of two years since this intervention (long-term-BC). Patients were also stratified by previous chemotherapy exposure (ChT+ and ChT-). Plasma levels of 25-hydroxyvitamin D [25(OH)D] (25(OH)D) were compared with data from 294 healthy women (non-BC) by linear regression to estimate β-coefficients using non-BC participan…

Increased risk of angiosarcoma secondary to cancer radiotherapy: Case series and review of the treatment options.

2020

Angiosarcomas (ASs) are aggressive tumors of vascular endothelial origin, occurring sporadically or in association with prior radiotherapy or chronic lymphedema. With only 1-5% of all sarcomas, the incidence seems low, but for the affected patient due to the extremely poor prognosis and the limited treatment options, the fate is often inevitable. Radiotherapy, chemotherapy, or "target therapy" have been used in the management of AS, but represent individual case decisions without lasting evidence. Over the past few years, breast-conserving surgery followed by radiation therapy, known as breast-conserving therapy (BCT), is being employed as a standard treatment for early-stage breast cancer,…

Evaluation of routine follow-up after surgery for breast carcinoma.

1986

Close postoperative follow-up of patients with breast cancer permits the early detection of possible recurrence of disease. Such follow-up allows for the detection of a tumor mass, that is small enough to permit adequate treatment leading to an increased survival time and better quality of life. Thus we studied 85 patients treated by radical mastectomy in stages I, II, and III during the period from December 1977 to June 1982. Among 82 patients, 41 had axillary node involvement and received adjuvant chemotherapy with C.M.F. All patients received a strict follow-up. Thirty-two patients showed recurrence of the disease, with 28. 1% being discovered while still asymptomatic. Seventy-five perce…

Anthracyclines and regional myocardial damage in breast cancer patients. A multicentre study from the Working Group on Drug Cardiotoxicity and Cardio…

2021

Abstract Aims In breast cancer (BC) patients treated with anthracyclines-based therapies, we aim at assessing whether adjuvant drugs impact cardiac function differently and whether their cardiotoxicity has a regional pattern. Methods and results In a multicentre study, 146 BC patients (56 ± 11 years) were prospectively enrolled and divided into three groups according to the received treatments: AC/EC-Group (doxorubicin or epirubicin + cyclophosphamide), AC/EC/Tax-Group (AC/EC + taxanes), FEC/Tax-Group (fluorouracil + EC + taxanes). Fifty-six patients of the total cohort also received trastuzumab. Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) were calculated …
