Multiplexed high-throughput immune cell imaging in patients with high-risk triple negative early breast cancer: Analysis from the International Breast Cancer Study Group (IBCSG) Trial 22-00.

BACKGROUND: Triple-negative breast cancer (TNBC) is the most aggressive breast cancer (BC) subtype, with dismal prognosis and limited option in advanced settings, yet stromal tumor infiltrating lymphocytes (sTILs) in this subtype has a predictive role. PATIENTS AND METHODS: The International Breast Cancer Study Group (IBCSG) Trial 22-00 is a randomized phase III clinical trial testing the efficacy of low-dose metronomic oral Cyclophosphamide-Methotrexate (CM) maintenance following standard adjuvant chemotherapy treatment for early-stage hormone receptor-negative breast cancer patients. A case-cohort sampling was used. We characterized immune cells infiltrates in patients with TNBC by 6 plex immunofluorescence (IF) staining for CD4, FOXP3, CD3, cytokeratine and CD8 RESULTS: We confirmed that high immune CD3+ T cells as well as stromal and intra-epithelial Tregs (CD4+Foxp3+ T cells) infiltrates were associated with a better Distant Recurrence-Free Interval (DRFI), especially in LN+ patient, regardless of the treatment. More importantly, we showed that the spatial distribution of immune cells at baseline is crucial, as CM maintenance was detrimental for T cells excluded LN+ TNBC patients. CONCLUSIONS: immune spatial classification on immune cells infiltrates seems crucial and could help patients' selection in clinical trial and greatly improve responses to specific therapies.

Final results of the real-life observational VICTOR-6 study on metronomic chemotherapy in elderly metastatic breast cancer (MBC) patients.

Nowadays, treatment of metastatic breast cancer (MBC) has been enriched with novel therapeutical strategies. Metronomic chemotherapy (mCHT) is a continuous and frequent administration of chemotherapy at a lower dose and so whit less toxicity. Thus, this strategy could be attractive for elderly MBC patients. Aim of this analysis is to provide insights into mCHT's activity in a real-life setting of elderly MBC patients. Data of patients ≥ 75 years old included in VICTOR-6 study were analyzed. VICTOR-6 is a multicentre, Italian, retrospective study, which collected data on mCHT in MBC patients treated between 2011 and 2016. A total of 112 patients were included. At the beginning of mCHT, median age was 81 years (75-98) and in 33% of the patients mCHT was the first line choice. Overall Response Rate (ORR) and Disease Control Rate (DCR) were 27.9% and 79.3%, respectively. Median PFS ranged between 7.6 and 9.1 months, OS between 14.1 and 18.5 months. The most relevant toxicity was the hematological one (24.1%); severe toxicity (grade 3-4) ranged from 0.9% for skin toxicity up to 8% for hematologic one. This is a large study about mCHT in elderly MBC patients, providing insights to be further investigated in this subgroup of frail patients.

Overall survival in the OlympiA phase III trial of adjuvant olaparib in patients with germline pathogenic variants in BRCA1/2 and high-risk, early breast cancer.

BACKGROUND: The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS: One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS: With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION: With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Doctors as Resource Stewards? Translating High-Value, Cost-Conscious Care to the Consulting Room.

After many policy attempts to tackle the persistent rise in the costs of health care, physicians are increasingly seen as potentially effective resource stewards. Frameworks including the quadruple aim, value-based health care and choosing wisely underline the importance of positive engagement of the health care workforce in reinventing the system-paving the way to real affordability by defining the right care. Current programmes focus on educating future doctors to provide 'high-value, cost-conscious care' (HVCCC), which proponents believe is the future of sustainable medical practice. Such programmes, which aim to extend population-level allocation concerns to interactions between an individual doctor and patient, have generated lively debates about the ethics of expanding doctors' professional accountability. To empirically ground this discussion, we conducted a qualitative interview study to examine what happens when resource stewardship responsibilities are extended to the consulting room. Attempts to deliver HVCCC were found to involve inevitable trade-offs between benefits to the individual patient and (social) costs, medical uncertainty and efficiency, and between resource stewardship and trust. Physicians reconcile this by justifying good-value care in terms of what is in the best interest of individual patients-redefining the currency of value from monetary costs to a patient's quality of life, and cost-conscious care as reflective medical practice. Micro-level resource stewardship thus becomes a matter of working reflexively and reducing wasteful forms of care, rather than of making difficult choices about resource allocation.

Pathologic complete response (pCR) to neoadjuvant treatment with or without atezolizumab in triple-negative, early high-risk and locally advanced breast cancer: NeoTRIP Michelangelo randomized study.

BACKGROUND: High-risk triple-negative breast cancers (TNBCs) are characterized by poor prognosis, rapid progression to metastatic stage and onset of resistance to chemotherapy, thus representing an area in need of new therapeutic approaches. Programmed death-ligand 1 (PD-L1) expression is an adaptive mechanism of tumour resistance to tumour-infiltrating lymphocytes, which in turn are needed for response to chemotherapy. Overall, available data support the concept that blockade of PD-L1/programmed cell death protein 1 checkpoint may improve efficacy of classical chemotherapy. PATIENTS AND METHODS: Two hundred and eighty patients with TNBC were enrolled in this multicentre study (NCT002620280) and randomized to neoadjuvant carboplatin area under the curve 2 and nab-paclitaxel 125 mg/m2 intravenously (i.v.) on days 1 and 8, without (n = 142) or with (n = 138) atezolizumab 1200 mg i.v. on day 1. Both regimens were given q3 weeks for eight cycles before surgery followed by four cycles of an adjuvant anthracycline regimen. The primary aim of the study was to compare event-free survival (EFS), and an important secondary aim was the rate of pathological complete response (pCR defined as the absence of invasive cells in breast and lymph nodes). The primary population for all efficacy endpoints is the intention-to-treat (ITT) population. RESULTS: The ITT analysis revealed that pCR rate after treatment with atezolizumab (48.6%) did not reach statistical significance compared to no atezolizumab [44.4%: odds ratio (OR) 1.18; 95% confidence interval 0.74-1.89; P = 0.48]. Treatment-related adverse events were similar with either regimen except for a significantly higher overall incidence of serious adverse events and liver transaminase abnormalities with atezolizumab. CONCLUSIONS: The addition of atezolizumab to nab-paclitaxel and carboplatin did not significantly increase the rate of pCR in women with TNBC. In multivariate analysis, the presence of PD-L1 expression was the most significant factor influencing the rate of pCR (OR 2.08). Continuing follow-up for the EFS is ongoing, and molecular studies are under way.

Metronomic chemotherapy (mCHT) in metastatic triple-negative breast cancer (TNBC) patients: results of the VICTOR-6 study.

PURPOSE: Triple-negative breast cancer (TNBC) represents a subtype of breast cancer which lacks the expression of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2): TNBC accounts for approximately 20% of newly diagnosed breast cancers and is associated with younger age at diagnosis, greater recurrence risk and shorter survival time. Therapeutic options are very scarce. Aim of the present analysis is to provide further insights into the clinical activity of metronomic chemotherapy (mCHT), in a real-life setting. METHODS: We used data included in the VICTOR-6 study for the present analysis. VICTOR-6 is an Italian multicentre retrospective cohort study, which collected data of metastatic breast cancer (MBC) patients who have received mCHT between 2011 and 2016. Amongst the 584 patients included in the study, 97 were triple negative. In 40.2% of the TNBC patients, mCHT was the first chemotherapy treatment, whereas 32.9% had received 2 or more lines of treatment for the metastatic disease. 45.4% out of 97 TNBC patients received a vinorelbine (VRL)-based regimen, which resulted in the most used type of mCHT, followed by cyclophosphamide (CTX)-based regimens (30.9%) and capecitabine (CAPE)-based combinations (22.7%). RESULTS: Overall response rate (ORR) and disease control rate (DCR) were 17.5% and 64.9%, respectively. Median progression free survival (PFS) and overall survival (OS) were 6.0 months (95% CI: 4.9-7.2) and 12.1 months (95% CI: 9.6-16.7). Median PFS was 6.9 months for CAPE-based regimens (95% CI: 5.0-18.4), 6.1 months (95% CI: 4.0-8.9) for CTX-based and 5.3 months (95% CI: 4.1-9.5) for VRL-based ones. Median OS was 18.2 months (95% CI: 9.1-NE) for CAPE-based regimens and 11.8 months for VRL- (95% CI: 9.3-16.7 and CTX-based ones (95%CI: 8.7-52.8). Tumour response, PFS and OS decreased proportionally in later lines. CONCLUSION: This analysis represents the largest series of TNBC patients treated with mCHT in a real-life setting and provides further insights into the advantages of using this strategy even in this poor prognosis subpopulation.

Toward High-Value, Cost-Conscious Care - Supporting Future Doctors to Adopt a Role as Stewards of a Sustainable Healthcare System.

PHENOMENON: In order to tackle the persistent rise of healthcare costs, physicians as "stewards of scarce resources" could be effective change agents, extending cost containment efforts from national policy to the micro level. Current programs focus on educating future doctors to deliver "high-value, cost-conscious care" (HVCCC). Although the importance of HVCCC education is increasingly recognized, there is a lag in implementation. Whereas recent efforts generated effective interventions that promote HVCCC in a local context, gaps persist in the examination of system factors that underlie broader successful and lasting implementation in educational and healthcare practices. APPROACH: We conducted a realist evaluation of a program focused on embedding HVCCC in postgraduate education by encouraging and supporting residents to set up "HVCCC projects" to promote HVCCC delivery. We interviewed 39 medical residents and 10 attending physicians involved in such HVCCC projects to examine HVCCC implementation in different educational and healthcare contexts. We held six reflection sessions attended by the program commissioners and educationalists to validate and enrich the findings. FINDINGS: A realist evaluation was used to unravel the facilitators and barriers that underlie the implementation of HVCCC in a variety of healthcare practices. Whereas research activities regularly stop after the identification of facilitators and barriers, we used these insights to formulate four high-value, cost-conscious care carriers: (1) continue to promote HVCCC awareness, (2) create an institutional structure that fosters HVCCC, (3) continue the focus on projects for embedding HVCCC in practice, (4) generate evidence. The carriers support residents, attendings and others involved in educating physicians in training to develop and implement innovative HVCCC projects. INSIGHTS: Strategies to promote physician stewardship go beyond the formal curriculum and require a transformation in the informal educational system from one that almost exclusively focuses on medical discussions to one that also considers value and cost as part of medical decision-making. The HVCCC carriers propose a set of strategies and system adaptations that could aid the transformation toward a HVCCC supporting context.

An International Society of Bipolar Disorders task force report: Precursors and prodromes of bipolar disorder.

OBJECTIVES: To clarify the clinical features preceding the onset of bipolar disorder (BD) has become a public health priority for the prevention of high morbidity and mortality. BD remains frequently under- or misdiagnosed, and under- or mistreated, often for years. METHODS: We assessed the predictive value of precursors and prodromes of BD. We assessed precursors of first-lifetime manic or hypomanic episodes with/without mixed features in retrospective and prospective studies. The task force evaluated and summarized separately assessments of familial risk, premorbid personality traits, retrospective, and prospective studies. RESULTS: Cyclothymic features, a family history of BD, retrospectively reported attenuated manic symptoms, prospectively identified subthreshold symptoms of hypomania, recurrence of depression, panic anxiety and psychotic features, have been identified as clinical precursors of BD. The prodromal symptoms like [hypo]mania often appears to be long enough to encourage early identification and timely intervention. CONCLUSIONS: The predictive value of any risk factor identified remains largely unknown. Prospective controlled studies are urgently needed for prevention and effective treatment.

Metronomic chemotherapy for advanced breast cancer patients in the real world practice: Final results of the VICTOR-6 study.

Metronomic chemotherapy (mCHT) refers to the minimum biologically effective dose of a chemotherapy agent given as a continuous dosing regimen, with no prolonged drug-free breaks, that leads to antitumor activity. Aim of the present study is to describe the use of mCHT in a retrospective cohort of metastatic breast cancer (MBC) patients in order to collect data regarding the different types and regimens of drugs employed, their efficacy and safety. Between January 2011 and December 2016, data of 584 metastatic breast cancer patients treated with mCHT were collected. The use of VRL-based regimens increased during the time of observation (2011: 16.8% - 2016: 29.8%), as well as CTX-based ones (2011: 17.1% - 2016: 25.6%), whereas CAPE-based and MTX-based regimens remained stable. In the 1st-line setting, the highest ORR and DCR were observed for VRL-based regimens (single agent: 44% and 88%; combination: 36.7% and 82.4%, respectively). Assuming VRL-single agent as the referee treatment (median PFS: 7.2 months, 95% CI: 5.3-10.3), the longest median PFS were observed in VRL-combination regimens (9.5, 95%CI 88.8-11.3, HR = 0.72) and in CAPE-single agent (10.7, 95%CI 8.3-15.8, HR = 0.70). The VICTOR-6 study provides new data coming from the real-life setting, by adding new information regarding the use of mCHT as an option of treatment for MBC patients.

Fertility concerns, preservation strategies and quality of life in young women with breast cancer: Baseline results from an ongoing prospective cohort study in selected European Centers.

OBJECTIVES: Most research addressing needs and concerns of young patients with breast cancer (≤40 years) is retrospective. The HOHO European protocol is a prospective multicenter cohort study of young women with newly diagnosed breast cancer, about fertility, psychosocial and quality of life concerns. Here we report the baseline data and focus on predictors of fertility concerns. MATERIALS AND METHODS: Patient surveys and medical record review were used. The baseline survey included sociodemographic, medical and treatment data as well as questions on fertility concerns and preservation strategies. Subscales from the CAncer Rehabilitation Evaluation System-Short Form (CARES-SF) were administered to measure specific quality of life aspects. Uni- and multivariable modeling were used to investigate predictors of greater fertility concern. RESULTS: Among 297 eligible respondents, 67% discussed fertility issues before starting therapy, 64% were concerned about becoming infertile after treatment, and 15% decided not to follow prescribed therapies. Fifty-four percent of women wished future children before diagnosis; of these, 71% still desired biologic children afterwards. In multivariable analysis, not having children was the only patient characteristic significantly associated with fertility concerns at diagnosis. Twenty-seven percent used fertility preservation strategies. Women who received chemotherapy reported greater physical (p = 0.021) and sexual difficulties (p = 0.039) than women who did not. Women who were married or had a partner reported less psychosocial problems than single women (p = 0.039). CONCLUSIONS: Young women with newly diagnosed breast cancer have several concerns, including, but not limited to, fertility. The HOHO European study provides valuable information to develop targeted interventions.

Metformin plus chemotherapy versus chemotherapy alone in the first-line treatment of HER2-negative metastatic breast cancer. The MYME randomized, phase 2 clinical trial.

PURPOSE: To investigate the efficacy of metformin (M) plus chemotherapy versus chemotherapy alone in metastatic breast cancer (MBC). METHODS: Non-diabetic women with HER2-negative MBC were randomized to receive non-pegylated liposomal doxorubicin (NPLD) 60 mg/m2 + cyclophosphamide (C) 600 mg/m2 × 8 cycles Q21 days plus M 2000 mg/day (arm A) versus NPLD/C (arm B). The primary endpoint was progression-free survival (PFS). RESULTS: One-hundred-twenty-two patients were evaluable for PFS. At a median follow-up of 39.6 months (interquartile range [IQR] 24.6-50.7 months), 112 PFS events and 71 deaths have been registered. Median PFS was 9.4 months (95% CI 7.8-10.4) in arm A and 9.9 (95% CI 7.4-11.5) in arm B (P = 0.651). In patients with HOMA index < 2.5, median PFS was 10.4 months (95% CI 9.6-11.7) versus 8.5 (95% CI 5.8-9.7) in those with HOMA index ≥ 2.5 (P = 0.034). Grade 3/4 neutropenia was the most common toxicity, occurring in 54.4% of arm A patients and 72.3% of the arm B group (P = 0.019). M induced diarrhea (G2) was observed in 8.8% of patients in Arm A. The effect of M was similar in patients with HOMA index < 2.5 and ≥ 2.5, for PFS and OS. CONCLUSIONS: The MYME trial failed to provide evidence in support of an anticancer activity of M in combination with first line CT in MBC. A significantly shorter PFS was observed in insulin-resistant patients (HOMA ≥ 2.5). Noteworthy, M had a significant effect on CT induced severe neutropenia. Further development of M in combination with CT in the setting of MBC is not warranted.

Clinical and Environmental Risk Factors for Bipolar Disorder: Review of Prospective Studies.

LEARNING OBJECTIVES: After participating in this activity, learners should be better able to:• Evaluate factors that have been identified in prospective studies as predicting the onset of bipolar disorder ABSTRACT: The prodromal phase of bipolar disorder (BD) remains incompletely characterized, limiting early detection of BD and delaying interventions that might limit future morbidity and disability. Retrospective and family-risk studies have consistently found evidence of prodromal psychopathology in subjects later diagnosed with BD. Here, we review prospective studies of clinical risk factors and exposures identified before diagnosis of BD: our findings are consistent with those from retrospective and family-risk studies. Affective psychopathology often precedes diagnosis to suggest a homotypic trajectory in developing BD. Early non-affective (heterotypic) psychopathological disturbances, including anxiety and disruptive behavior disorders, as well as environmental factors and exposures, have been found in prospective studies to increase the risk of BD, but tend to lack specificity in predicting BD. Findings from prospective studies are encouragingly similar to those of retrospective and family-risk studies.

Selecting patients for resection after primary chemotherapy for non-metastatic pancreatic adenocarcinoma.

BACKGROUND: Patients with borderline (BL) or locally advanced (LA) pancreatic adenocarcinoma are usually treated with primary chemotherapy (CT), followed by resection when feasible. Scanty data are available about the criteria to candidate patients to resection after CT. PATIENTS AND METHODS: Between 2002 and 2016 overall 223 patients diagnosed with BL or LA pancreatic adenocarcinoma were primarily treated with Gemcitabine combination (4-drugs or nab-paclitaxel-gemcitabine) for 3-6 months followed by surgery and/or chemoradiation. Resection was carried out when radical resection could be predicted by imaging studies and intraoperative findings. The prognostic value of both pre-treatment factors and treatment response was retrospectively evaluated, searching for criteria that could improve the selection of patients for surgery. RESULTS: Median survival (MS) for the whole population was 18.3 months. Surgical resection was carried out in 61 patients; MS in resected patients was significantly longer (30.0 months) as compared with 162 non-resected patients (16.5 months) (P < 0.00001). According to response criteria, 48% had a radiological partial response, 47% a stable disease and 5% a disease progression); CA19.9 response (reduction >50%) was obtained in 77.8% of patients. Among resected patients, neither pre-treatment factors, including BL/LA distinction, nor radiological response, were able to prognosticate survival differences. Survival of resected patients having no CA19.9 response was significantly lower as compared with responders (MS 15.0 versus 31.5 months, P = 0.04), and was similar to non-responders patients that did not undergo resection (MS 10.9 months, P= 0.25). Multivariate analysis carried out on the overall population, showed that Karnofsky performance status, T3-T4 status, resection and CA19.9 response were independent prognostic factors, while radiological response, BL/LA distinction and baseline CA19.9 had not significant influence on survival. CONCLUSIONS: CA19.9 response may allow a better selection of patients who will benefit from resection after primary CT for BL or LA pancreatic adenocarcinoma.

Parental Reports of Prodromal Psychopathology in Pediatric Bipolar Disorder.

OBJECTIVES: Early psychopathology in children diagnosed with Bipolar Disorder (BD) remains poorly characterized. Parental retrospective reports provide helpful details on the earliest manifestations and their evolution over time. These symptoms occur early in the course of BD, often before a formal diagnosis is made and/or treatment is implemented, and are of great importance to early recognition and prevention. METHODS: Parents of pre-pubertal children and adolescents with DSM-IV diagnoses of BD attending an outpatient mood disorders clinic provided retrospective ratings of 37 symptoms of child psychopathology. Stability and comorbidity of diagnoses were evaluated, and severity of symptoms for each subject was assessed by identifying the earliest occurrence of the reported symptoms causing impairment. RESULTS: Severe mood instability, temper tantrums, anxiety symptoms, sleep disturbances and aggression were among the most common signs of psychopathology reported in children diagnosed with BD before puberty. Symptoms were already apparent in the first three years in 28%, and formal diagnoses were made before the age of 8 y in the majority of cases. CONCLUSIONS: Retrospective parental reports of early symptoms of psychopathology in pre-pubertal children with BD revealed a very early occurrence of affective precursors (irritability and mood dysregulation) and clinical risk factors like impulsive aggression and anxiety that can precede the syndromal onset of mania by several years. These findings support previous reports suggesting a progression of symptoms from abnormal, non-specific presentations to sub-threshold and finally syndromal BD. The importance of early identification and intervention is discussed.

Incidence and management of diarrhea in patients with HER2-positive breast cancer treated with pertuzumab.

Background: Pertuzumab disrupts heterodimerization between human epidermal growth factor receptor 2 (HER2) and epidermal growth factor receptor (EGFR), HER3, and HER4. Thus, pertuzumab could result in adverse events similar to those observed with EGFR antagonists, such as diarrhea. We report the incidence and severity of diarrhea observed with pertuzumab in the CLEOPATRA, NeoSphere, and TRYPHAENA studies. Patients and methods: Patients (n = 1443) had metastatic [CLEOPATRA (n = 804)] or early-stage breast cancer [NeoSphere (n = 416) and TRYPHAENA (n = 223)]. The incidence and severity of diarrhea were analyzed by treatment received. The incidence of febrile neutropenia concurrent with diarrhea and the effect of pre-existing gastrointestinal comorbidities were also evaluated. Subgroup analyses were carried out using CLEOPATRA data. Results: The incidence of all-grade diarrhea across studies was generally greater for pertuzumab-based treatment, ranging from 28% to 72% (grade 1, 21%-54%; grade 2, 8%-37%; grade 3, 0%-12%; grade 4, 0%). Incidence was highest during the first pertuzumab-containing cycle, decreasing with subsequent cycles. Dose delays or discontinuations due to diarrhea were infrequent, ranging from 0% to 8%. Among pertuzumab-treated patients with diarrhea, 47%-67% received pharmacological intervention, most commonly with loperamide. Overlap between diarrhea and febrile neutropenia was uncommon, ranging from 0% to 11%. No relationship was observed between pre-existing gastrointestinal comorbidities and diarrhea. In CLEOPATRA, patients ≥65 years treated with pertuzumab had a higher incidence of grade 3 diarrhea than patients <65 years (19% versus 8%). All-grade diarrhea occurred at greater frequency among pertuzumab-treated Asian versus white patients with metastatic breast cancer (74% versus 63%); the corresponding rates in the control arm were 53% and 45%, respectively. Conclusions: In both the metastatic and early-stage breast cancer settings, diarrhea was common but manageable for all pertuzumab-containing regimens. Diarrheal episodes were mainly low grade and occurred most often during the first treatment cycle. Diarrheal-related drug delays or discontinuations were uncommon. ClinicalTrials.gov identifiers: NCT00567190 (CLEOPATRA), NCT00545688 (NeoSphere), NCT00976989 (TRYPHAENA).

Child and Adolescent Clinical Features Preceding Adult Suicide Attempts.

The objective of this study was to identify the predictive value of juvenile factors for adult suicidal behavior. We reviewed clinical records to compare factors identified in childhood and adolescence between adult suicidal versus nonsuicidal major affective disorder subjects. Suicide attempts occurred in 23.1% of subjects. Age-at-first-symptom was 14.2 vs. 20.2 years among suicidal versus nonsuicidal subjects (p < 0.0001). More prevalent in suicidal versus non-suicidal subjects by multivariate analysis were: depressive symptoms, hyper-emotionality, younger-at-first-affective-episode, family suicide history, childhood mood-swings, and adolescence low self-esteem. Presence of one factor yielded a Bayesian sensitivity of 64%, specificity of 50%, and negative predictive power of 86%. Several juvenile factors were associated with adult suicidal behavior; their absence was strongly associated with a lack of adult suicidal behavior.

What is the role of conventional antidepressants in the treatment of major depressive episodes with Mixed Features Specifier?

The newly introduced Mixed Features Specifier of Major Depressive Episode and Disorder (MDE/MDD) is especially challenging in terms of pharmacological management. Prior to the publication of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the symptoms of the mixed features specifier were intradepressive hypomanic symptoms, always and only associated with bipolar disorder (BD). Intradepressive hypomanic symptoms, mostly referred to as depressive mixed states (DMX), have been poorly characterized, and their treatment offers significant challenges. To understand the diagnostic context of DMX, we trace the nosological changes and collocation of intradepressive hypomanic symptoms, and examine diagnostic and prognostic implications of such mixed features. One of the reasons so little is known about the treatment of DMX is that depressed patients with rapid cycling, substance abuse disorder, and suicidal ideation/attempts are routinely excluded from clinical trials of antidepressants. The exclusion of DMX patients from clinical trials has prevented an assessment of the safety and tolerability of short- and long-term use of antidepressants. Therefore, the generalization of data obtained in clinical trials for unipolar depression to patients with intradepressive hypomanic features is inappropriate and methodologically flawed. A selective review of the literature shows that antidepressants alone have limited efficacy in DMX, but they have the potential to induce, maintain, or worsen mixed features during depressive episodes in BD. On the other hand, preliminary evidence supports the effective use of some atypical antipsychotics in the treatment of DMX.
