Interdisciplinary Screening, Diagnosis, Therapy and Follow-up of Breast Cancer. Guideline of the DGGG and the DKG (S3-Level, AWMF Registry Number 032/045OL, December 2017) - Part 2 with Recommendations for the Therapy of Primary, Recurrent and Advanced Breast Cancer

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Method The process of updating the S3 guideline published in 2012 was based on the adaptation of identified source guidelines. They were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and with the results of a systematic search of literature databases followed by the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point and used them to develop suggestions for recommendations and statements, which were then modified and graded in a structured consensus process procedure. Recommendations Part 2 of this short version of the guideline presents recommendations for the therapy of primary, recurrent and metastatic breast cancer. Loco-regional therapies are de-escalated in the current guideline. In addition to reducing the safety margins for surgical procedures, the guideline also recommends reducing the radicality of axillary surgery. The choice and extent of systemic therapy depends on the respective tumor biology. New substances are becoming available, particularly to treat metastatic breast cancer.

Interdisciplinary Screening, Diagnosis, Therapy and Follow-up of Breast Cancer. Guideline of the DGGG and the DKG (S3-Level, AWMF Registry Number 032/045OL, December 2017) - Part 1 with Recommendations for the Screening, Diagnosis and Therapy of Breast Cancer

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Methods The process of updating the S3 guideline dating from 2012 was based on the adaptation of identified source guidelines which were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and the results of a systematic search of literature databases and the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point to develop recommendations and statements which were modified and graded in a structured consensus procedure. Recommendations Part 1 of this short version of the guideline presents recommendations for the screening, diagnosis and follow-up care of breast cancer. The importance of mammography for screening is confirmed in this updated version of the guideline and forms the basis for all screening. In addition to the conventional methods used to diagnose breast cancer, computed tomography (CT) is recommended for staging in women with a higher risk of recurrence. The follow-up concept includes suggested intervals between physical, ultrasound and mammography examinations, additional high-tech diagnostic procedures, and the determination of tumor markers for the evaluation of metastatic disease.

Establishment of Over-The-Scope-Clips (OTSC®) in daily endoscopic routine

BACKGROUND

Alongside the evolution of interventional endoscopy, the need for a more sophisticated closure tool tailored to the treatment of new challenging indications has been increasing rapidly.

METHODS

We here present our collected data on 262 Over-The-Scope-Clip (OTSC®) placements in a total of 233 interventions at our institution. Follow-up was focused on clinically lasting success with regards to different indications.

RESULTS

Immediate success of OTSC® treatment was observed in 87.1% of all sessions (203/233). The success rates per indication were as follows: spontaneous bleeding 84.8% (28/33); iatrogenic bleeding 100% (20/20); acute perforation 90.3% (65/72); prophylaxis for perforation 100% (24/24); anastomotic leakage 61.1% (11/18); fistulae 80.7% (46/57); diameter reduction of the gastrojejunal anastomosis 100% (6/6); and stent fixation 100% (3/3). At 30-day follow-up, the overall success rate was 67.4% (157/233). The success rates per indication were as follows: spontaneous bleeding 69.7% (23/33); iatrogenic bleeding 90% (18/20); acute perforation 86.1% (62/72); prophylaxis for perforation 100% (24/24); anastomotic leakage 33.3% (6/18); fistulae 29.8% (17/57), diameter reduction of the gastrojejunal anastomosis 83.3% (5/6); and stent fixation 66% (2/3).

CONCLUSIONS

Our cohort confirms previous data on the clinical usefulness of the OTSC® in daily routine practice.

Expression of the breast differentiation antigen NY-BR-1 in a phyllodes tumor of the vulva

We describe a phyllodes tumor of borderline malignancy in the labium majus of a 49-year-old woman. The histogenetic origin of phyllodes tumors in the vulva is controversial. Strong immunoreactivity for NY-BR-1, a novel breast differentiation antigen, was demonstrated within the epithelial components of the phyllodes tumor. A similar expression pattern was observed in mammary-like glands of the vulva. These findings provide further evidence that phyllodes tumors of the vulva might derive from mammary-like glands in the labium majus or from ectopic breast tissue.

[Loss of metastatic deposits in breast sentinel lymph nodes during intra-operative frozen section analysis]

The intraoperative evaluation of sentinel lymph nodes is an ongoing debated issue. In this review we discuss different approaches to sentinel lymph node processing in an intra operative setting and in the consecutive embedding in paraffin. We propose a method, which uses routine intra operative examination of lymph nodes with stereo microscopy with selected frozen section analysis. We demonstrate preliminary data on a larger patient collective along with data on a control group. We could show in our study that a higher rate of metastates can be achieved avoiding intra operative frozen sections on grossly inconspicuous sentinel lymph nodes.

[Screening of Chlamydia trachomatis: is the diagnostic efficacy good enough?]

OBJECTIVE

In the background of discrepant results of C. trachomatis testing in women with suspected genital infections, three different tests have been compared.

METHOD

594 endocervical swabs were collected from women visiting the family planning clinic in Aarau. Each of the following tests was evaluated: Cobas Amplicor Chlamydia trachomatis, IF Chlamyset, and Chlamydia IF direct. If one of these three tests was positive, the fixed material on the slides was scraped off, and a PCR was performed.

RESULTS

15 out of 594 samples were "true'-positive. PCR recognized 14 of them, the IF Chlamyset 13, and the Chlamydia IF 8. With the IF Chlamyset 37 samples were false-positive.

CONCLUSIONS

PCR testing exhibits a good sensitivity and a high specificity, but we think that the sensitivity can be increased by improving the sample preparation step. The Chlamydia IF direct has a good specificity, but a rather low sensitivity. It should be noted that the PCR has the potential to become a new gold standard for the detection of C. trachomatis.

[Interlocking intramedullary nailing of the femur: is the advantage of early mobilization gained by risking a malposition?]

We report a follow-up of 57 consecutive femoral fractures treated by internal fixation with the AO Universal Interlocking Nall. All fractures (91% follow-up) had healed within a mean of 22 months (range 9-50) after operation. Full weight-bearing was possible after an average of 9 weeks (range 2-20). The only infection occurred after a secondary open lengthening osteotomy. In 5 cases a rotational malposition or length discrepancy had to be corrected shortly after initial surgery. Rotational malposition in excess of 10 degrees occurred in 26% of cases (mostly external rotation) and length discrepancy exceeding 1 cm in 13% (mostly shortening). The frequency of malposition is explained by the absence of rotational or length control during operation. We recommend that malposition be correlated without delay by reoperation.

[Splenectomy: surgical indications in malignant hematologic diseases]

Indications for splenectomy in malignant hematological diseases are discussed for relief of symptoms (splenomegaly, cytopenias), for staging (M. Hodgkin) or improvement of survival (hairy cell leukemia). The role of splenectomies is also evaluated for Non-Hodgkin lymphomas, chronic lymphatic leukemia, myelofibrosis and for chronic myeloic leukemia.

The immune response evokes changes in brain noradrenergic neurons

A decreased noradrenaline turnover in the hypothalami of rats was observed at the peak of the immune response to sheep red blood cells. The decrease in noradrenergic neuronal activity was mimicked by injection of soluble r mediators released by immunological cells activated in vitro. Noradrenaline also tended to decrease in the brainstem but not in the residual brain. It is suggested that products released from activated immunological cells during the immune response may induce the previously described autonomic and endocrine mechanisms that contribute to immunoregulation.
