Abstract OT1-06-02: Oncotype DX®-REMAR(Rhein-Main-Registry)-study: Use of the oncotype DX® assay in early breast cancer in certified breast cancer centers in Rhine-Main Region, Germany

A brief background discussion:

The OncotypeDX® multigene assay is recommended by several international guidelines as a predictive and prognostic factor for HR+/HER2- early breast cancer (EBC). Several trials have shown the necessity of OncotypeDX® Recurrence Score (RS) as a decision tool for HR+/HER2- EBC with 0-3 lymph nodes (LN) involved. At present, though, only limited data from the routine setting are available on the impact of treatment decision making process based on the usage of classical proliferation marker Ki67 with or without knowing the individual RS prior and after a treatment decision from a multidisciplinary tumor board (MTB) for the decision making of the adjuvant therapy of EBC. The Oncotype DX® assay is still not reimbursed by every insurance, therefore we expect that this registry will have an impact on reimbursement in Germany.

Trial design:

The OncotypeDX®-REMAR(Rhein-Main-Registry) study is a prospective, non-interventional, multicenter and non-randomized, study. 13 certified breast cancer (BC) centers in the Rhine-Main region in Germany participate. The sponsor of this trial is the AGAPLESION, Markus Hospital Frankfurt, Genomic Health provides the financial support.

After registration, the patient´s case will be discussed in the respective institution's MTB, before and after the RS result. The adjuvant treatment will be recommended based on available clinical and histopathological data according to the guidelines and the RS result. After each meeting, the physician and patient will fill in a questionnaire. In addition to the local determination of Ki67 and nuclear grading, a central pathology assessment of these two markers will be provided in a blinded fashion. Only the sponsor has access to these results. Consequently, this independent test has no influence both on the local histopathology result and on the recommended treatment.

Eligibility criteria:

Inclusion criteria:

Female patients, ≥18 years, with a hormone-receptor positive, HER2-negative EBC and 0-3 positive LN, T1-3, nuclear grading 1-3, Ki67:10-40%, cM0.

Specific aims:

Primary endpoint is the decision impact of the RS result in patients with mid-range Ki67 on adjuvant chemotherapy in EBC.

Secondary endpoints include the correlation of Ki67 with tumor grade and RS result. Moreover, an economic subanalysis will be done.

Statistical methods:

The change in physicians' treatment recommendations will be measured pre-assay vs. post-assay. The proportion of patients for whom the treatment recommendation changed and the 95% confidence interval will be reported overall and by select groups. McNemar's test will be used to compare the proportion of patients' recommended chemo-hormonal therapy pre-assay vs. post-assay.

Present accrual and target accrual:

Thirteen participating centers recruited 97 patients by the end of April 2017. 600 patients are planned in total.

Diagnosis and Therapy of Female Pelvic Organ Prolapse. Guideline of the DGGG, SGGG and OEGGG (S2e-Level, AWMF Registry Number 015/006, April 2016)

Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

Indications and Route of Hysterectomy for Benign Diseases. Guideline of the DGGG, OEGGG and SGGG (S3 Level, AWMF Registry No. 015/070, April 2015)

Background: Official guideline "indications and methods of hysterectomy" to assign indications for the different methods published and coordinated by the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (OEGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). Besides vaginal and abdominal hysterectomy, three additional techniques have been implemented due to the introduction of laparoscopy. Organ-sparing alternatives were also integrated. Methods: The guideline group consisted of 26 experts from Germany, Austria and Switzerland. Recommendations were developed using a structured consensus process and independent moderation. A systematic literature search and quality appraisal of benefits and harms of the therapeutic alternatives for symptomatic fibroids, dysfunctional bleeding and adenomyosis was done through MEDLINE up to 6/2014 focusing on systematic reviews and meta-analysis. Results: All types of hysterectomy led in studies to high rates of patient satisfaction. If possible, vaginal instead of abdominal hysterectomy should preferably be done. If a vaginal hysterectomy is not feasible, the possibility of a laparoscopic hysterectomy should be considered. An abdominal hysterectomy should only be done with a special indication. Organ-sparing interventions also led to high patient satisfaction rates, but contain the risk of symptom recurrence. Conclusion: As an aim, patients should be enabled to choose that therapeutic intervention for their benign disease of the uterus that convenes best to them and their personal life situation.

The positive influence of methotrexate on the mortality of patients with rheumatoid arthritis is partly independent of its effect on disease activity: results of a re-evaluation 18 years after baseline

OBJECTIVES

Methotrexate (MTX) is the anchor drug in the treatment of patients with rheumatoid arthritis (RA). MTX shows effects on disease activity and mortality. However, it is unclear whether the effect of MTX on mortality depends on its effect on disease activity.

METHODS

In a post-hoc analysis we analysed the data of our cohort established in Ratingen, Germany, and included all patients starting treatment with MTX (n=271) between 1980 and 1987. One year after baseline (BL), response to MTX treatment was assessed using a modified ACR 20 response. Follow-up data of 250 patients were available after 10 and 18 years.

RESULTS

After 1 year, there were 66% responders and 20% non-responders; only 14% had discontinued MTX treatment due to side effects or lack of efficacy. Most patients continued MTX treatment irrespective of efficacy. Ten years after BL, 61% of the patients were still treated with MTX. After 18 years, the responder-group showed a standardised mortality ratio of 1.6 compared to 3.2 for the group of non-responders. However, when adjusting for age, gender, response to MTX treatment one year after BL, number of swollen joints and comorbidities after 10 years an independent association of continued MTX treatment with lower mortality was found for the period 10 to 18 years after BL (hazard ratio (HR): 0.63, 95% confidence interval: 0.43-0.92, p=0.015).

CONCLUSIONS

In this cohort, the mortality lowering effect of continued MTX use was partly independent of its effect on disease activity. This finding may affect treatment decisions concerning RA patients with insufficient response to MTX.

[Thieno[3,4-c]quinoline-4-yl-amines--synthesis and investigation of activity against malaria]

The 4-aryl derivative 3, obtained by Suzuki cross coupling of the methyl 4-bromothiophene-3-carboxylate (2) with 2-nitrophenylboronic acid cyclizes under reductive conditions pH-dependant to yield the tricyclic hydroxamic acid 4 or the lactam 5. The chlorothieno[3,4-c]quinoline 6 was formed by reaction of the lactam 5 with P,P-dichlorophenylphosphinoxide. The amines 7-14 were synthesized from the chloroimine 6. Compounds 7a,b, 8, 9, 10b, 11, 12 and 14a, b were tested for in vitro antimalarial activity using the chloroquine sensitive 3D7 and the chloroquine resistant Plasmodium falciparum strain Dd2. The highest activity were shown by 10b with IC50 values of 130 nM and 50 nM, respectively and by 11 with IC50 values of 190 nM and 44 nM, respectively.

Risk of facial palsy and severe Frey's syndrome after conservative parotidectomy for benign disease: analysis of 610 operations

CONCLUSIONS

Advanced age, long operation time and large specimen volume were significant risk factors for transient facial palsy after conservative parotidectomy. Revision operation was the only risk factor for development of a permanent palsy. Risk factors for Frey's syndrome were not found. The incidence of Frey's syndrome was not altered by the use of a sternocleidomastoid muscle flap or other implantation material.

OBJECTIVES

The results of studies identifying risk factors for facial palsy and Frey's syndrome after parotidectomy are contradictory. This study attempted to identify these risk factors by performing a retrospective review of a large series of patients.

PATIENTS AND METHODS

A total of 610 standardized conservative parotidectomies for benign diseases performed between 1989 and 2004 were studied retrospectively. The risk factors for facial palsy and Frey's syndrome were determined by univariate and if possible by multivariate analysis of variables related to patient demographics and operation characteristics.

RESULTS

The rates of transient facial palsies, permanent facial palsies and Frey's syndrome were 18%, 4%, and 4%, respectively. Significant univariate and multivariate risk factors for development of a transient facial palsy were age>70 years, operation time>260 min, and a specimen volume>70 cm3. The only significant risk factor for the development of a permanent palsy was prior surgery. A significant risk factor for the development of Frey's syndrome could not be estimated.
