Does the use of an online decision aid (DA) about fertility preservation (FP), in addition to standard counselling by a specialist in reproductive medicine, reduce decisional conflict compared to ...standard counselling alone?
Female cancer patients who could make use of the online DA had a significantly lower short-term decisional conflict score.
Nowadays, female cancer patients have several options for preserving fertility, but having to decide whether to opt for FP within a short time frame after cancer diagnosis and before the start of treatment is challenging. According to previous studies focussing mainly on breast cancer patients, decisional conflict among these women is high, and they have expressed the need for additional support.
The study was a randomized controlled trial including female cancer patients who were referred by their treating oncologist to a specialist in reproductive medicine for fertility counselling. Participants were randomly assigned to the control group (counselling only) or to the intervention group (counselling and additional use of the online DA immediately after counselling). Recruitment was ongoing from July 2016 to December 2017 at eight fertility centres in Switzerland and Germany.
The online DA was developed by an interdisciplinary team of specialists in reproductive medicine, gynaecologists, oncologists and psychologists. Of 79 recruited participants, 59 completed the first assessment and could therefore be enrolled in the study. They were asked to complete an online questionnaire at three time points: at T1, after counselling (control group, n = 27) or after counselling and the additional use of the DA (intervention group, n = 24); at T2, 1 month later (N = 41: control group, n = 23; intervention group, n = 18); and at T3, 12 months later (N = 37: control group, n = 20; intervention group, n = 17). The survey comprised questions about fertility-related knowledge, attitude towards FP, willingness to undergo FP and socio-demographic data, as well as the decisional conflict and decisional regret scales.
All participants showed low decisional conflict scores. Women who used the online DA in addition to counselling (intervention group) showed a significantly lower total score on the Decisional Conflict Scale (DCS) compared to the control group at T1 (P = 0.008; M = 12.15, SD = 4.38; 95% CI, 3.35-20.95) and at T2 (P = 0.043; M = 9.35, SD = 4.48; 95% CI, 0.31-18.38). At T3, the mean total score of the DCS was still lower in the intervention group compared to the control group; however, this group difference was no longer significant (P = 0.199, M = 6.86, SD = 5.24; 95% CI, -3.78 to 17.51). The majority of participants had already made a decision regarding FP (yes or no) at T1 (72.5%): 91.7% in the intervention group compared to 55.6% in the control group (P = 0.014). Those who had decided already at T1 showed significantly lower decisional conflict (P = 0.007; M = 13.69, SD = 4.89; 95% CI, 3.86-23.52). The average number of DA sessions per user was 2.23, and 80.8% of the participants completed the DA's value clarification exercises. Participants in the intervention group were satisfied with the DA and would recommend it to other patients.
The recruitment of participants was challenging because of the emotionally difficult situation patients were in. This led to the limited sample size for final analysis. Education levels were high in two-thirds of the participants. It is difficult to say whether the DA would be equally effective in women with a lower educational background.
There is evidence that the DA served as a helpful complement to the decision-making process for young female cancer patients qualifying for FP. This is, to our knowledge, the first randomized controlled trial evaluating a DA targeted at patients with several cancer types and in a language other than English (i.e. German). This study contributes to extending the range of the still limited number of DAs in the context of FP.

Journal Article
Cancer initiation and progression follow complex molecular and structural changes in the extracellular matrix and cellular architecture of living tissue. However, it remains poorly understood how the ...transformation from health to malignancy alters the mechanical properties of cells within the tumour microenvironment. Here, we show using an indentation-type atomic force microscope (IT-AFM) that unadulterated human breast biopsies display distinct stiffness profiles. Correlative stiffness maps obtained on normal and benign tissues show uniform stiffness profiles that are characterized by a single distinct peak. In contrast, malignant tissues have a broad distribution resulting from tissue heterogeneity, with a prominent low-stiffness peak representative of cancer cells. Similar findings are seen in specific stages of breast cancer in MMTV-PyMT transgenic mice. Further evidence obtained from the lungs of mice with late-stage tumours shows that migration and metastatic spreading is correlated to the low stiffness of hypoxia-associated cancer cells. Overall, nanomechanical profiling by IT-AFM provides quantitative indicators in the clinical diagnostics of breast cancer with translational significance.
Our aim was to prospectively evaluate inter- and intra-observer agreement between Breast Imaging Reporting and Data System (BI-RADS) classifications and Tsukuba elasticity scores (TSs) of breast ...lesions. The study included 164 breast lesions (63 malignant, 101 benign). The BI-RADS classification and TS of each breast lesion was assessed by the examiner and twice by three reviewers at an interval of 2 months. Weighted κ values for inter-observer agreement ranged from moderate to substantial for BI-RADS classification (κ = 0.585–0.738) and was substantial for TS (κ = 0.608–0.779). Intra-observer agreement was almost perfect for ultrasound (US) BI-RADS (κ = 0.847–0.872) and TS (κ = 0.879–0.914). Overall, individual reviewers are highly self-consistent (almost perfect intra-observer agreement) with respect to BI-RADS classification and TS, whereas inter-observer agreement was moderate to substantial. Comprehensive training is essential for achieving high agreement and minimizing the impact of subjectivity. Our results indicate that breast US and real-time elastography can achieve high diagnostic performance.
The aim of the study was to get deeper insight into the significance of fertility in cancer patients, their attitude towards fertility preservation (FP), decisional conflicts, and patient’s needs in ...the decision-making process. Focus groups with 12 female cancer survivors were held and revealed that the significance of fertility was high and attitude towards FP positive. Religious and ethical reservations were not negligible. Standardized decision aids were considered helpful. More support is highly in demand and specific tools would be beneficial.
Anthracycline- and taxane-based adjuvant chemotherapies are the most frequently used systemic treatments for women with triple negative breast cancer (TNBC). Adding platinum derivatives in the ...neo-adjuvant setting has been shown to not only improve the pCR rates, but also the 3 year DFS for TNBC patients; however, data on platinum derivatives in the adjuvant setting are limited.
We conducted a retrospective, single-center study in a Swiss breast cancer cohort to evaluate the role of carboplatin in addition to standard adjuvant therapy (anthracyclines and/ or taxanes) in early TNBC patients. All patients with stage I-III TNBC who underwent primary breast surgery between 2004 and 2014 were included.
Eighty-three patients were included in the analysis. Stage and grade were well balanced between patients treated with standard chemotherapy (
=54; cohort A) or standard chemotherapy plus carboplatin (
=29; cohort B). The median time to local relapse (LRFS) was 15.0 months in cohort A
16.0 months in cohort B (
=0.655). The median time to distant relapse (DRFS) was 29.5 months in cohort A
25.0 months in cohort B (
=0.606) There was also no difference in overall survival between the two cohorts (mean overall survival 98 and 91 months, respectively;
=0.208).
Our data suggest that in an unselected cohort of early TNBC patients, the addition of carboplatin in the adjuvant setting may not be beneficial with respect to relapse-free and overall survival. Further prospective trials to evaluate the addition of platinum in the adjuvant setting are warranted, especially to define subgroups of TNBC patients, which might benefit from carboplatin therapy.
The study aimed to improve breast cancer diagnosis with new ultrasound (US) modalities. We examined whether real-time elastography (RTE) complements the diagnostic performance of US.
The Ethical ...Committee approved the study. Patients provided written informed consent and received a whole breast workup. Breast lesions were evaluated by US and RTE. Lesions were assessed by BI-RADS, Tsukuba score (TS) and strain ratio (SR).
The study included 164 breast lesions of which 101 were benign and 63 malignant. Women with benign lesions were predominantly premenopausal with sonographic dense breast tissue. Women with breast cancer were mostly postmenopausal, with a low sonographic density. Benign lesions had a mean TS of 2.05, which was significantly lower than the mean TS of 3.25 for malignant lesions. The SR for benign lesions (SR 1.83) was significantly smaller than for breast cancer (SR 4.83). Sensitivity and specificity was 95 and 81% for BI-RADS, 39 and 94% for TS, and 57 and 83% for SR, with a cutoff at 2.5. The combination of BI-RADS, TS and SR yielded a sensitivity of 95% and a specificity of 85%.
Besides morphologic features revealed by US, elastic properties of breast lesions obtained by RTE can be exploited for diagnostic breast imaging.
Peritoneal biopsies (PB) and peritoneal washing (PW) are routine measures in abdominal staging of gynecological malignancies and are used particularly for the assessment of occult microscopic tumor ...spread to the peritoneal surface including the diaphragm. Cytological diaphragmatic smears (DS) have been suggested as a supplemental tool; however, they are not routinely taken and their usefulness is still unclear. The present study retrospectively evaluated whether DS provide an additional benefit over PB and PW for the detection of peritoneal malignancies in patients with gynecological cancer. The data from patients who underwent laparotomy for suspected gynecological cancer and had DS and either PB, PW or ascites were reviewed. Sensitivity and specificity, and the number upstaged patients were determined. A total of 43 patients were excluded due to benign diagnosis (those with negative DS or PW) and 2 out of the remaining had 2 carcinomas simultaneously. Among these 41 malignancies, DS were positive in 12, PW in 18 and PB in 19 cases. No case was DS-positive while negative for both PB and PW. Four cases were missed when only PB and 5 when only PW was performed. Notably, no case of peritoneal disease was identified solely on positive DS, indicating that all 23 positive cases (presence of occult peritoneal disease in 56.1%) were identified by PB and PW together (100% sensitivity; 62% specificity). In addition, none of the cases was upstaged solely on positive DS results. Taken together, these data demonstrated that DS do not present an additional benefit to PW and PB in the detection of peritoneal gynecological disease.
Background
Whereas specimen radiography (SR) is an established strategy for intraoperative resection margin analysis during breast-conserving surgery for nonpalpable lesions, the use of frozen ...section analysis (FSA) is still a matter of debate.
Methods
A retrospective review was conducted of 115 consecutive operations in which the two objectives sought were the excision of nonpalpable malignant lesions and breast conservation. Breast surgery was performed in the Gynecology and the Surgery Departments at the Basel University Hospital Breast Center. Whereas one department preferably uses SR for intraoperative margin assessments of lesions involving ductal carcinoma in situ (DCIS) or atypical ductal hyperplasia, the other uses FSA to increase the rate of complete removal of these lesions with a single procedure. The respective accuracy and therapeutic impact of these two techniques are compared here.
Results
Intraoperative resection margin assessments were performed with FSA in 80 and SR in 35 of a total of 115 operations performed on 111 patients with pTis, pT1, or pT2 nonpalpable breast cancer. FSA diagnostic accuracy, sensitivity, and specificity were 83.8%, 80.0%, and 87.5%, respectively, compared to 60%, 60%, and 60%, respectively, for SR. FSA tended to have a stronger therapeutic impact than SR in terms of the number of patients in whom initially positive margins were rendered margin-negative thanks to intraoperative analysis and immediate reexcision or mastectomy (27.5% vs. 14.3%;
p
= 0.124). More importantly, significantly fewer secondary reexcisions were performed in the FSA series than in the SR series (12.5% vs. 37.1%;
p
= 0.002). Finally, the intraoperative detection of invasive cancer with FSA led to a significantly lower number of secondary procedures for axillary lymph node staging (5% vs. 25.7%;
p
= 0.001).
Conclusions
The present results suggest that FSA may be more accurate than SR for analyzing intraoperative resection margins during breast-conserving surgery for nonpalpable lesions.
Preeclampsia is a leading cause of maternal and fetal/neonatal mortality and morbidity worldwide. The early identification of patients with an increased risk for preeclampsia is therefore one of the ...most important goals in obstetrics. The availability of highly sensitive and specific physiologic and biochemical markers would allow not only the detection of patients at risk but also permit a close surveillance, an exact diagnosis, timely intervention (e.g. lung maturation), as well as simplified recruitment for future studies looking at therapeutic medications and additional prospective markers. Today, several markers may offer the potential to be used, most likely in a combinatory analysis, as predictors or diagnostic tools. We present here the current knowledge on the biology of preeclampsia and review several biochemical markers which may be used to monitor preeclampsia in a future, that, we hope, is not to distant from today.
