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.

Re-excision Rates and Local Recurrence in Breast Cancer Patients Undergoing Breast Conserving Therapy

Background: Controversy continues over the impact of re-excision (RE) on local recurrence (LR) in patients with invasive breast cancer. Patients and Methods: We investigated factors which could effect RE rates in patients undergoing breast-conserving or oncoplastic surgery. Between 2000 and 2003, 489 patients with stage pT1-pT2 or pN0/1 tumors were evaluated. 74 patients fulfilled the inclusion criteria. Patients were categorized into 3 groups: no RE (n = 25), RE during primary surgery (n = 28), and RE performed during secondary or even tertiary procedure (n = 21). All tumor slides were re-evaluated by a pathologist specializing in breast cancer. Results: Mean follow-up was 70 months with an overall LR rate of 4.1 %. Binary logistic regression revealed no tumor-specific risk factors for RE. There was no LR in the group of patients who did not have RE. There was one case of LR in the group of patients who had RE during primary surgery. Two cases of LR were observed in the group of patients who had two or more surgical procedures. Conclusion: New risk factors for increased RE rates were not observed, reflecting the inconsistent data on risk factors for RE. However, breast cancers should be excised in a single procedure and oncoplastic procedures should be considered.

Different prediction of distant recurrence risk in primary breast cancer patients stratified by ER and ERBB2 status

20120

Background: Molecular profiling recently defined biological characteristics of several long-recognized breast cancer subtypes including ER-positive (luminal subtype), ER-negative/ERBB2-positive (ERBB2 subtype) and ER-negative/ErBB2-negative (basal-like subtype). Each of these particular subtypes has different impact on patient outcome and should be therefore taken in consideration for individual scoring calculations. Methods: The quantitative RNA expression levels of 70 relevant genes were simultaneously determined in fresh frozen samples of 317 primary breast cancer (BC) patients comprehending ER-positive (70%), ER-negative/ERBB2-positive (15%) and ERBB2-negative/ER-negative (15%) and with known follow-up data. Five years distant recurrence scoring systems were calculated by means of Cox-hazard regression models. Results: Two main prognostic scoring systems were developed: one based on genes relative to proliferation representing tumor growth and its velocity, the other based on proteases. A low proliferation score identified 30% of patients at very good prognosis (probability of distant recurrence 12%, CI: 1.5–22%) all belonging to the ER-positive subcategory as compared to cases with higher proliferation (probability of distant recurrence 31%, 32–38%). The probability to develop distant recurrence within 5 years for 30% of ERBB2-positive patients was of only 12% (CI 0–25%) when accompanied by low levels of proteases as compared to the remaining ERBB2-positive patients with a probability of recurrence of 40% (CI 22–54%). Conclusions: ER, ERBB2 and the expression levels of the few identified genes involved in tumor proliferation and invasion can be easily and precisely detected by means of QRT-PCR. This robust method allows fine tuned prognosis and gives predictive information for the treatment of individual breast cancer.

Breast cancer sagittal/horizontal plane location influences axillary lymph node involvement

AIM

To assess the influence of tumour location on axillary lymph node involvement (ALNI) and prognosis in breast cancer by evaluating the significance of the sagittal/horizontal alignment.

METHODS

We compared 57 patients with superficially located breast carcinomas up to 3.0 cm with patients having lesions in posterior planes of the breast. Both groups were matched according to age, time of diagnosis, tumour size, grade, hormonal receptor status and tumour site within the frontal plane. Histologic evidence of skin involvement, excluding tumours fulfilling the criteria for pT4b, was defined as inclusion criteria and reference plane for superficial tumour location.

RESULTS

Tumours situated in the superficial region of the breast, compared to those located in deeper planes, have an increased risk of ALNI (p=0.023), whereas no difference was observed with reference to disease-specific survival (p=0.203).

CONCLUSION

This study shows that ALNI is dependent on sagittal/horizontal as well as frontal tumour location. Clinicians should be aware that tumours lying posteriorly may be at increased risk of occult spread outside axillary lymph nodes.

Scope and significance of non-uniform classification practices in breast cancer with non-inflammatory skin involvement: a clinicopathologic study and an international survey

BACKGROUND

The study evaluates the scope of non-uniform classification practices concerning breast carcinomas with non-inflammatory skin involvement.

PATIENTS AND METHODS

We compared the clinical course of patients with histologically proven non-inflammatory skin involvement: 119 (65.4%) with clinically obvious 'classical' skin changes (Group A) and 63 (34.6%) with no or only discreet changes (Group B). A questionnaire was circulated to pathology departments in 24 countries to assess the practice concerning the placement of skin- involved breast carcinomas in the TNM classification.

RESULTS

Patients in Group B showed a significantly better disease specific survival (P=0.0002). Eighty-six respondents (70.5%) of the survey preferred the 'histological view' and classified tumors with only histological proven skin involvement as T 4 b/stage IIIB. The opposing classification principle ('clinical view'), which dictates that T 4 b breast cancer is a clinical diagnosis and the classical signs must be present, was supported by 31 respondents (25.4%).

CONCLUSIONS

A large number of breast cancer patients with non-inflammatory skin involvement are only histologically proven and show, compared with cases exhibiting the classical clinical signs, significant differences in clinical course and prognosis. In general, both subsets were aggregated in one T category/stage (T 4 b/IIIB). This results in a considerable distortion of the reported statistical data.

[Innovative concepts for surgical treatment of the carcinoma of the breast]

Breast conserving therapy is a stable element in primary breast cancer treatment. Conservation and also restoration of the breast improve the outcome concerning psychological aspects. Surgical interventions include techniques for classical breast conservation as well as oncoplastic procedures like reduction mammaplasties and different types of flaps. Theses modern surgical procedures should be realised in a breast center.

Prognostic and predictive significance of ErbB-2 breast tumor levels measured by enzyme immunoassay

PURPOSE

A retrospective analysis to assess the prognostic and predictive clinical value of breast tumor ErbB-2 receptor expression quantified by enzyme immunoassay (EIA), to compare levels measured by EIA with ErbB-2 status determined by immunohistochemistry (IHC), and to correlate receptor content with levels of phosphorylated (Y1248-P) ErbB-2, a measure of functional tyrosine kinase activity.

MATERIALS AND METHODS

EIA quantification of ErbB-2 was performed on membrane extracts from 3,208 well-characterized primary breast cancers. Overall, relapse-free, distant disease-free, and local/regional-free patient survival data were available on 1,123 of these tumors. IHC scoring for ErbB-2 status (HercepTest; DAKO, Glostrup, Denmark) was performed on adjacent sections of 151 cases, and receptor functionality was measured in 230 tumors by an antibody specific for phosphorylated (Y1248-P) ErbB-2.

RESULTS

Unlike nonmalignant breast tissues, breast tumors showed increased ErbB-2 levels in a bimodal distribution, with 12% constituting a distinct set of ErbB-2-overexpressing tumors. The intermodal threshold value for ErbB-2 overexpression distinguished tumors with reduced estrogen and progesterone receptor content, high IHC score for ErbB-2, and significantly increased levels of phosphorylated (Y1248-P) ErbB-2 receptor. By multivariate analysis, EIA-determined ErbB-2 overexpression predicted significantly reduced patient survival that was unaffected by tamoxifen or cyclophosphamide, methotrexate, and fluorouracil adjuvant therapy.

CONCLUSION

Determination of ErbB-2 receptor expression by EIA offers a clinically valuable alternative to semiquantitative IHC assessment of breast tumor ErbB-2 overexpression and affords the opportunity to evaluate ErbB-2 phosphorylation, which may represent an important predictive parameter of receptor functionality.

MIB-1 (Ki-67) immunostaining of breast cancer cells in cytologic smears

OBJECTIVE

The reliability of immunocytochemical evaluation of proliferation activity was tested using the monoclonal antibody MIB-1 on cytologic specimens.

STUDY DESIGN

The study comprised 83 frozen tissue smears (FTSs) and 51 fine needle aspirates (FNAs) from 119 breast cancer patients. MIB-1 labeling indexes (LIs) were compared with various tumor parameters assessed on histologic material.

RESULTS

MIB-1 LIs established on cytologic smears were significantly different in ductal and lobular carcinomas (P = .024) and correlated significantly with mitotic activity (P < .0001), histologic grade (P < .0001) and S-phase fraction (P < .0001). Essentially the same results were obtained on FTSs and FNAs.

CONCLUSION

Proliferative activity can reliably be evaluated by FNA cytology, and the evaluation of MIB-1 LIs may complement cytologic grading of breast cancer. The evaluation of proliferation activity may, therefore, contribute to the selection of candidates for adjuvant chemotherapy.

[Breast preserving therapy of breast carcinoma: analysis of over 1,300 patients treated in the Basel region]

From 1977 to 1994 a total of 1329 breast cancer patients have been treated with breast conserving surgery in the region of Basel. This analysis is based on 832 patients treated from 1977 to 1990 according to a prospective treatment protocol, which was adjusted only once (1985). In comparison with the most known international publications this analysis represents one of the greatest homogeneous series of breast conserving treatment. We observe an overall 5-year survival of 91% and a 10-year survival rate of 77%. 94% of the women remain locally recurrence free at 5 years and 86% at 10 years respectively. At 5 years, freedom of local recurrence totals to 97% in patients without (pN0) and to 89% in patients with tumor involvement of the axillary lymph nodes (pN+) (p = 0.00008), as well as to 96% for pT1 and 91% for pT2-tumors (p = 0.08328). In our analysis the R0-resection significantly influences local recurrence free survival.

[Diagnostic problems in local recurrence after breast saving treatment]

353 patients with stages pTis, pT1-2, pN0-1, cM0 breast cancer have been treated consecutively by breast conserving therapy in a prospective, nonrandomized study at the University Hospital Basel and the Women's Clinic Rheinfelden/Baden/Germany. The median age was 47 years, the median follow-up time 67 months, and 4% only of this collective were lost to follow-up after a median time of 42 months. In 79% of the cases the tumor was excised totally, while in 19% the resection margins were positive and in 2% only the margins were not available for histological judgement. The rate of local failure reached 8% with a median time interval of 53 months. 116 patients showed postactinic induration in the primary tumor region. 73 of these were given additional diagnostic examination: The postactinic induration was judget clinically suspicious in 51 cases and clinically nonsuspicious of local failure in 22 cases. All 73 patients received additional examination by mammography and biopsy. By comparison with the histological results the clinical results were correct in 59% and false in 41%, while the mammographic results were correct in 82% and false in 18% of the cases.

[On the vocational counselling of physically disabled young people--some remarks on the findings presented by E.-M. Weinwurm-Krause (author's transl)]

Hand in hand with the continuing development of vocational counselling for disabled young people went to updating and differentiation of vocational orientation material available to the disabled for preparing their choice of occupation. Increased attention had above all been paid to counselling of the thalidomide-affected. Their concerns, especially as regards assessment of aptitudes and inclinations, are particularly headed in vocational guidance, an instrument that had been defined more specifically in the late seventies. The vocational education centres must be considered an essential aid in the training of, particularly, the physically disabled as the required accompanying services (for medical, psychological and social educational care) can be made available here. By means of training regulations for the disabled, as provided for in the Vocational Education Act and the handicrafts ordinance, these training facilities for the disabled are also most readily in a position to make allowances in view of the nature and consequences of a disability, when this is held to be necessary by the vocational counselling service due to the professional opinions presented by psychologists and/or physicians. No rehabilitation measure can however be initiated unless the disabled young person and his or her parents consent.
