Objetivo: conhecer as dificuldades elencadas pelos profissionais de saúde na assistência pré-natal às usuárias de substâncias psicoativas. Método: estudo qualitativo, exploratório-descritivo, realizado nas mídias sociais, com profissionais da área da saúde que realizam atendimento pré-natal. A coleta de dados ocorreu de novembro de 2022 a janeiro de 2023 por meio de questionário eletrônico. Os dados foram analisados por meio da análise temática. Protocolo aprovado pelo Comitê de Ética em Pesquisa. Resultados: os profissionais destacam o déficit de conhecimento para abordar este público em específico. A abordagem superficial e condenatória do uso de substâncias pelas políticas públicas corrobora para que os profissionais se sintam preparados em parte para atender essas gestantes. Considerações finais: a capacitação dos profissionais é necessária para superar práticas condenatórias e retrógradas de cuidado que focam unicamente a abstinência; como também, o investimento na capacitação acerca da rede de atenção à saúde, buscando ampliar sua visibilidade e utilização.

Objective: understanding the difficulties listed by health professionals in prenatal care for users of psychoactive substances. Method: this is a qualitative, exploratory-descriptive study carried out on social media with health professionals who provide prenatal care. Data was collected from November 2022 to January 2023 using an electronic questionnaire. The data was analyzed using thematic analysis. Protocol approved by the Research Ethics Committee. Results: the professionals highlight the lack of knowledge to deal with this specific public. The superficial and condemnatory approach to substance use by public policies contributes to making professionals feel partly prepared to deal with these pregnant women. Final considerations: the training of professionals is necessary to overcome condemnatory and retrograde care practices that focus solely on abstinence; and investment in training about the health care network, seeking to increase its visibility and use.

Real-world prevalence, treatment and survival of "high risk" early breast cancer, with mandatory testing of gBRCA1/2 mutation according to the OlympiA trial inclusion criteria: Data from a population-based registry.

BACKGROUND: The results of the OlympiA study led to the approval of a PARP inhibitor (olaparib) as adjuvant treatment for early breast cancer (eBC) at high risk of relapse in patients with a germline BRCA1/2 mutation (gBRCAm). However, the proportion of patients in routine practice who meet the "high-risk" criteria applied in the OlympiA study, and for whom gBRCAm testing would now be mandatory, remains unknown. PATIENTS AND METHODS: In this population-based study, we use unique data from the French specialized Côte d'Or Breast and Gynecological Cancer Registry, to assess the real-life proportion, and long-term prognosis of patients treated for eBC between 2005 and 2015 with standard treatment, and at "high risk" of relapse according to the OlympiA trial criteria. RESULTS: We included 3483 patients treated for HER2-negative eBC (N = 380 with ER-, and N = 3103 with ER + tumor). We found N = 62 (1.8 %) patients with gBRCA1/2 mutations. A total of 494 patients (14.2 %) were classified as "high risk" according to the Olympia criteria; 55 % with ER-tumors, and 9.1 % with ER + tumors, respectively. Despite more intensive systemic treatments in "high risk" patients, 10-year overall survival was much worse in these "high risk" patients compared to the others: 60.1 % vs 83.8 % in ER-tumors, and 55.4 % vs 84.1 % in ER + tumors. Our estimates of net survival show an even greater difference. CONCLUSION: This study provides real-life insights into the prevalence and prognosis of patients with high-risk eBC, in a context where the approval of adjuvant olaparib requires careful reorganization of care, so as not to overlook a patient with gBRCAm who could benefit from adjuvant olaparib.

Strategies for Identifying and Recruiting Women at High Risk for Breast Cancer for Research Outside of Clinical Settings: Observational Study.

BACKGROUND: Research is needed to understand and address barriers to risk management for women at high (≥20% lifetime) risk for breast cancer, but recruiting this population for research studies is challenging. OBJECTIVE: This paper compares a variety of recruitment strategies used for a cross-sectional, observational study of high-risk women. METHODS: Eligible participants were assigned female at birth, aged 25-85 years, English-speaking, living in the United States, and at high risk for breast cancer as defined by the American College of Radiology. Individuals were excluded if they had a personal history of breast cancer, prior bilateral mastectomy, medical contraindications for magnetic resonance imaging, or were not up-to-date on screening mammography per American College of Radiology guidelines. Participants were recruited from August 2020 to January 2021 using the following mechanisms: targeted Facebook advertisements, Twitter posts, ResearchMatch (a web-based research recruitment database), community partner promotions, paper flyers, and community outreach events. Interested individuals were directed to a secure website with eligibility screening questions. Participants self-reported method of recruitment during the eligibility screening. For each recruitment strategy, we calculated the rate of eligible respondents and completed surveys, costs per eligible participant, and participant demographics. RESULTS: We received 1566 unique responses to the eligibility screener. Participants most often reported recruitment via Facebook advertisements (724/1566, 46%) and ResearchMatch (646/1566, 41%). Community partner promotions resulted in the highest proportion of eligible respondents (24/46, 52%), while ResearchMatch had the lowest proportion of eligible respondents (73/646, 11%). Word of mouth was the most cost-effective recruitment strategy (US $4.66 per completed survey response) and paper flyers were the least cost-effective (US $1448.13 per completed survey response). The demographic characteristics of eligible respondents varied by recruitment strategy: Twitter posts and community outreach events resulted in the highest proportion of Hispanic or Latina women (1/4, 25% and 2/6, 33%, respectively), and community partner promotions resulted in the highest proportion of non-Hispanic Black women (4/24, 17%). CONCLUSIONS: Although recruitment strategies varied in their yield of study participants, results overall support the feasibility of identifying and recruiting women at high risk for breast cancer outside of clinical settings. Researchers must balance the associated costs and participant yield of various recruitment strategies in planning future studies focused on high-risk women.

Utilizing risk factors to guide treatment decisions in chronic lymphocytic leukemia.

INTRODUCTION: In the era of chemo-immunotherapy, high-risk factors unequivocally predicted inferior outcomes for patients with CLL. The widespread adoption of BTK inhibitors has challenged the practical implications of such testing, as many patients have improved outcomes despite the presence of high-risk features. The impact of adverse prognostic factors, such as unmutated IGHV, on survival has been ameliorated by continuous treatment with BTK inhibitors, but not by finite-duration therapy with venetoclax-based combinations. Furthermore, TP53 abnormalities continue to be associated with worse outcomes in the era of novel agents. New treatment modalities, such as pirtobrutinib, lisocabtagene maraleucel, and ongoing studies combining BTK inhibitors with venetoclax, raise new questions on the significance of prognostic factors of survival for patients with CLL. AREAS COVERED: Herein, we summarized the available literature on patients with CLL harboring high-risk biomarkers, with a focus on data from key clinical trials. EXPERT OPINION: Testing for prognostic biomarkers will remain relevant to identify patients who may have increased benefit from novel therapeutic strategies, such as combination therapies and novel agents. Patients with high-risk disease should be encouraged to participate in clinical trials.

Elective pelvic nodal irradiation in the setting of ultrahypofractionated versus moderately hypofractionated and conventionally fractionated radiotherapy for prostate cancer: Outcomes from 3 prospective clinical trials.

Background and purpose: Data is needed regarding the use of ultrahypofractionated radiotherapy (UHRT) in the context of prostate cancer elective nodal irradiation (ENI), and how this compares to conventionally fractionated radiotherapy (CFRT) ENI with CFRT or moderately hypofractionated radiotherapy (MHRT) to the prostate. Materials and methods: Between 2011-2019, 3 prospective clinical trials of unfavourable intermediate or high-risk prostate cancer receiving CFRT (78 Gy in 39 fractions to prostate; 46 Gy in 23 fractions to pelvis), MHRT (68 Gy in 25 fractions to prostate; 48 Gy to pelvis), or UHRT (35-40 Gy in 5 fractions to prostate +/- boost to 50 Gy to intraprostatic lesion; 25 Gy to pelvis) were conducted. Primary endpoints included biochemical failure (Phoenix definition), and acute and late toxicities (CTCAE v3.0/4.0). Results: Two-hundred-forty patients were enrolled: 90 (37.5 %) had CFRT, 90 (37.5 %) MHRT, and 60 (25 %) UHRT. Median follow-up time was 71.6 months (IQR 53.6-94.8). Cumulative incidence of biochemical failure (95 % CI) at 5-years was 11.7 % (3.5-19.8 %) for CFRT, 6.5 % (0.8-12.2 %) MHRT, and 1.8 % (0-5.2 %) UHRT, which was not significantly different between treatments (p = 0.38). Acute grade ≥ 2 genitourinary toxicity was significantly worse for UHRT versus CFRT and MHRT, but not for acute grade ≥ 3 genitourinary, or acute gastrointestinal toxicities. UHRT was not associated with worse late toxicities. Conclusion: ENI with UHRT resulted in similar oncologic outcomes to CFRT ENI with prostate CFRT/MHRT, with worse acute grade ≥ 2 GU toxicity but no differences in late toxicity. Randomized phase 3 trials of ENI using UHRT techniques are much anticipated.

Real-word outcomes for high-risk non-muscle-invasive bladder cancer: screened patients for the BRAVO trial.

OBJECTIVE: To report real-world outcomes for high-risk non-muscle-invasive bladder cancer (HRNMIBC), including bacillus Calmette-Guérin (BCG) and radical cystectomy (RC), as randomised comparisons of these have not been possible. METHODS: We detail consecutive participants screened for the BRAVO randomised controlled trial comparing RC with BCG (International Standard Randomised Controlled Trial Number [ISRCTN]12509361). Patients were prospectively registered and case-note review used for outcomes. The primary outcome was overall survival. Secondary outcomes included recurrence, progression, metastasis, and bladder cancer-specific survival. RESULTS AND LIMITATIONS: A total of 193 patients were screened, including 106 (54.9%) who received BCG, 43 (22.3%) primary RC, 37 (19.2%) 'other' treatment and seven (3.6%) hyperthermic intravesical mitomycin C. All-cause death occurred in 55 (28.5%) patients at median (interquartile range [IQR]) of 29.0 (19.5-42.0) months. In multivariable analysis, overall mortality was more common in older patients (hazard ratio [HR] 2.63, 95% confidence interval [CI] 1.35-5.13; Cox P = 0.004 for age >70 years), those recruited from district hospitals (HR 0.53, 95% CI 0.3-0.95; P = 0.032) and those who did not undergo RC as their first treatment (HR 2.16, 95% CI 1.17-3.99; P = 0.014). In all, 17 (8.8%) patients died from bladder cancer (BC) at median (IQR) of 22.5 (19-36.25) months. In multivariable analysis, BC-specific mortality was more common in older patients (HR 4.87, 95% CI 1.1-21.6; P = 0.037) and those with Tis/T1 disease (HR 2.26, 95% CI 1.23-4.16; P = 0.008) but did not vary with initial treatment. CONCLUSIONS: Patients with HRNMIBC are at high-risk of mortality. Those choosing RC as their initial treatment have lower risks of mortality than others, although this may reflect fitness and selection.

Treatment Outcomes and Definition Inconsistencies in High-Risk Unilateral Retinoblastoma: Outcomes and Definition Variances in High-Risk Rb.

PURPOSE: To compare the clinical outcomes of children with unilateral retinoblastoma (Rb) and high-risk histopathology features (HRHF) following upfront enucleation with/without adjuvant chemotherapy, and investigate cases locally considered non-HRHF but converted to a standardized HRHF definition. DESIGN: Retrospective multinational clinical cohort study. METHODS: Children with Rb who presented to 21 centers from 12 countries between 2011-2020, and underwent primary enucleation were recruited. Centers retrieved clinical data and were asked to report detailed histopathology findings, as well as indicate cases defined locally as high-risk. For analysis, only unilateral cases with standardized HRHF, defined as retrolaminar optic nerve invasion, massive choroidal invasion, scleral invasion, anterior-segment involvement, and/or combined non-massive choroidal and prelaminar/laminar optic nerve invasion, were included. Main Outcome Measures included orbital tumor recurrence, systemic metastasis, survival and number and outcome of cases converted to standardized HRHF. RESULTS: A total of 600 children presenting to 14 centers in 9 countries were included. Of these, 505 (84.2%) were considered locally as HRHF and received adjuvant chemotherapy. After a median follow-up period of 39.2±1.6 months (range: 0.8-60.0 months), 36 (6.0%) had orbital tumor recurrence, 49 (8.2%) metastasis, and 72 (12.0%) children died. Children not receiving adjuvant chemotherapy were at significantly increased risk of orbital tumor recurrence, metastasis, and death (p ≤0.002). Of the study children, 63/600 (10.5%) were considered locally non-HRHF, but converted to standardized HRHF and included in the analysis. Of these, 6/63 (9.5%) had orbital tumor recurrence, 5/63 (7.9%) metastasis, and 6/63 (9.5%) children died. Isolated minor choroidal invasion with prelaminar/laminar optic nerve invasion was reported in 114 (19.0%) children, but considered locally as HRHF only in 68/114 (59.6%). Of these, 6/114 (5.3%) children developed metastasis and subsequently died, yielding a number needed to treat of 15. CONCLUSION: Based on this multinational cohort of children with Rb, we recommend the use of adjuvant chemotherapy following upfront enucleation and diagnosis of HRHF. Variation exists worldwide among centers when defining HRHF, resulting in adverse patient outcomes, warranting standardization.

Dermatologic Conditions in Down Syndrome: A Multi-Site Retrospective Review of International Classification of Diseases Codes.

BACKGROUND AND OBJECTIVE: As the population and life expectancy of people with Down syndrome increases, identifying common skin conditions throughout the lifespan will help inform clinical care and research. We sought to evaluate dermatologic conditions diagnosed in pediatric and adult patients with Down syndrome. METHODS: This multicenter retrospective study analyzed demographic and outpatient visit International Classification of Diseases codes of patients with Down syndrome evaluated at outpatient dermatology clinics in the United States or Canada between 2011 and 2021. RESULTS: A total of 1529 patients with Down syndrome were identified from eight academic medical centers: 50.8% were children (0-12 years), 25.2% were adolescents (13-17 years), and 24% were adults (18 years and older). Eczematous dermatitis was the most common diagnosis overall (26%), followed by folliculitis (19.3%) and seborrheic dermatitis (15.6%). Other notable diagnoses included dermatophyte infections (13%), alopecia areata (11.6%), and psoriasis (6.7%). About 4.3% of visits included a code for high-risk medication use. Eczematous dermatitis, alopecia areata, and folliculitis were the most common diagnoses observed in children; folliculitis, hidradenitis suppurativa, and eczematous dermatitis in adolescents; and seborrheic dermatitis, eczematous dermatitis, and folliculitis in adults. CONCLUSIONS: Dermatologic conditions in patients with Down syndrome vary by age, but are most often eczematous, adnexal, and cutaneous autoimmune disorders. This multicenter retrospective review identifies skin diseases that should be prioritized for clinical care guideline development and research in the Down syndrome community.

Discrimination Between Benign and Malignant Lesions With Restriction Spectrum Imaging MRI in an Enriched Breast Cancer Screening Cohort.

BACKGROUND: Breast cancer screening with dynamic contrast-enhanced MRI (DCE-MRI) is recommended for high-risk women but has limitations, including variable specificity and difficulty in distinguishing cancerous (CL) and high-risk benign lesions (HRBL) from average-risk benign lesions (ARBL). Complementary non-invasive imaging techniques would be useful to improve specificity. PURPOSE: To evaluate the performance of a previously-developed breast-specific diffusion-weighted MRI (DW-MRI) model (BS-RSI3C) to improve discrimination between CL, HRBL, and ARBL in an enriched screening population. STUDY TYPE: Prospective. SUBJECTS: Exactly 187 women, either with mammography screening recommending additional imaging (N = 49) or high-risk individuals undergoing routine breast MRI (N = 138), before the biopsy. FIELD STRENGTH/SEQUENCE: Multishell DW-MRI echo planar imaging sequence with a reduced field of view at 3.0 T. ASSESSMENT: A total of 72 women had at least one biopsied lesion, with 89 lesions categorized into ARBL, HRBL, CL, and combined CLs and HRBLs (CHRLs). DW-MRI data were processed to produce apparent diffusion coefficient (ADC) maps, and estimate signal contributions (C1, C2, and C3-restricted, hindered, and free diffusion, respectively) from the BS-RSI3C model. Lesion regions of interest (ROIs) were delineated on DW images based on suspicious DCE-MRI findings by two radiologists; control ROIs were drawn in the contralateral breast. STATISTICAL TESTS: One-way ANOVA and two-sided t-tests were used to assess differences in signal contributions and ADC values among groups. P-values were adjusted using the Bonferroni method for multiple testing, P = 0.05 was used for the significance level. Receiver operating characteristics (ROC) curves and intra-class correlations (ICC) were also evaluated. RESULTS: C1, √C1C2, and log C 1 C 2 C 3 $$ \log \left(\frac{{\mathrm{C}}_1{\mathrm{C}}_2}{{\mathrm{C}}_3}\right) $$ were significantly different in HRBLs compared with ARBLs (P-values < 0.05). The log C 1 C 2 C 3 $$ \log \left(\frac{{\mathrm{C}}_1{\mathrm{C}}_2}{{\mathrm{C}}_3}\right) $$ had the highest AUC (0.821) in differentiating CHRLs from ARBLs, performing better than ADC (0.696), especially in non-mass enhancement (0.776 vs. 0.517). DATA CONCLUSION: This study demonstrated the BS-RSI3C could differentiate HRBLs from ARBLs in a screening population, and separate CHRLs from ARBLs better than ADC. TECHNICAL EFFICACY STAGE: 2.

A Rare Case of Placenta Increta at Uterine Fundus.

Adherent placenta means a placenta that is not delivered spontaneously or even after manual removal within 30 minutes of baby birth. It is an uncommon and frequently unanticipated event with serious potential health circumstances and it should be managed by the medical team. This case study presents a rare instance of placenta increta in a 25-year-old woman, second gravida, at 36 weeks of gestation, with a history of cesarean section 16 months prior due to chorioamnionitis. The patient presented to the labor room in active labor, and antenatal ultrasound indicated placental implantation on the posterior surface of the upper uterine segment. Given the short inter-delivery interval, an emergency preterm lower segment cesarean section (LSCS) was performed, resulting in the birth of a healthy baby girl weighing 1.8 kg. During surgery, a morbidly adherent placenta was found over the fundus of the uterus. Following consultations with the patient and her relatives, an emergency obstetric total hysterectomy was performed. Intraoperatively, the patient received one unit of packed cell volume (PCV) and, postoperatively, two additional units of PCV and two units of fresh frozen plasma (FFP) were administered. On the third postoperative day, the patient developed right lung consolidation, necessitating a five-day stay in the Obstetric Intensive Care Unit (OBICU). The remaining postoperative period was uneventful, and the patient was discharged on the 10th postoperative day with the healthy infant. Placenta accreta, including its variants increta and percreta, represents abnormal placental implantation into the uterine wall, a condition whose incidence is rising due to increased cesarean sections and improved imaging detection.

Interaction of High- and Low-Risk Human Papillomavirus Genotypes is Associated with a Reduced Risk of Developing Cervical Cancer.

INTRODUCTION: Cervical cancer is among the most common types of cancer in women and is associated with human papillomavirus (HPV) infection. The association between cervical cancer and high-risk HPV infection has been well documented. However, the effect of simultaneous infection with high- and low-risk HPV or low-risk HPV alone on the risk of developing cervical malignancy remains unanswered in guidelines. METHOD: We investigated the association of high and low-risk HPVs (HR or LR) genotypes with cervical carcinoma risk and pathological and cytological information in cases recruited from a population-based cohort study of 790 patients. Correlation matrix and t-test were used for analysis. RESULTS: The percentage of HR+LR and HR-HPV16/18 were 9.30% and 11.20% in class II, 7.15% and 7.10% in class IV, and 7.15% and 5.80% in As-CUS smears. Interestingly, concurrent infection with HR-HPV and LR-HPV types led to a significant reduction in the risk of developing malignancy compared to the high-risk group (OR=0.3 (0.098-0.925), pvalue=0.04). The percentage of individuals with cervical malignancy was 10.2% and 28.2% within the co-infected and the HR-HPV participants. CONCLUSION: Our findings suggest that simultaneous infection with high- and low-risk HPV may reduce the risk of cervical malignancy.

VCd versus VRd in Newly Diagnosed Multiple Myeloma: Matched Real-World Analysis from the Balkan Myeloma Study Group (BMSG).

BACKGROUND: Bortezomib, dexamethasone and cyclophosphamide (VCd) remains a popular regimen, due to its activity and low toxicity, while bortezomib, lenalidomide and dexamethasone (VRd) is widely used in US and Europe; both are combined with anti-CD38 monoclonal antibodies but VCd and VRd have not been compared directly in adequately powered prospective trials. AIM: We compared the outcomes of 1216 patients treated with VCd (N = 690) or VRd (N = 526) in a real-world setting. RESULTS: Patients treated with VCd had more often severe renal dysfunction, ISS-3 disease, hypercalcemia, elevated LDH, anemia, thrombocytopenia, poor performance while VRd-treated were older and received less often autologous transplant but more frequently maintenance but the duration of induction was similar. VRd was associated with substantially higher overall response and CR/VGPR rates to induction(P < .001) and improved PFS and OS in univariate analysis, especially among patients with standard risk disease, without renal dysfunction and in the elderly; however, in multivariate analysis there was no significant difference in either PFS or OS. In patients strictly matched 1:1 for major prognostic variables (188 in each group, total N = 376), the superiority of VRd in terms of responses rates and depth of response was confirmed, but without significant PFS or OS difference. CONCLUSION: VRd is a more active induction regimen than VCd, although use of maintenance with lenalidomide may dilute the PFS or OS benefit. VCd induction remains an option in special circumstances. With the implementation of monoclonal antibodies, VCd backbone can be considered for patients without access to or who do not tolerate VRd.

Practical Guidance on Abemaciclib in Combination with Adjuvant Endocrine Therapy for Treating Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative High-Risk Early Breast Cancer.

The most common subtype of breast cancer is hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer, accounting for 65-70% of all breast cancer cases diagnosed in the United States. Until 2015, single-agent endocrine therapy (ET) was the recommended first-line treatment for metastatic HR-positive, HER2-negative breast cancer. However, the paradigm has since shifted, as targeted therapy is now recommended in combination with ET. The cyclin-dependent kinase (CDK) 4/6 inhibitors have revolutionized the treatment of this breast cancer subtype, and combining either palbociclib, ribociclib, or abemaciclib with ET is now the standard first-line treatment for metastatic disease. Results of clinical trials in the metastatic setting have demonstrated that treatment with the combination of a CDK4/6 inhibitor and ET rather than ET alone is associated with longer overall survival, longer progression-free survival, and better objective response rates. Each of the CDK4/6 inhibitors has been investigated in combination with ET in patients with early-stage HR-positive, HER2-negative breast cancer who are at high risk of relapse. In October 2021, abemaciclib was the first CDK4/6 inhibitor approved in combination with ET by the US Food and Drug Administration for adjuvant treatment of patients with HR-positive, HER2-negative, high-risk early breast cancer. Herein, we provide practical guidance on the use of abemaciclib in combination with ET for HR-positive, HER2-negative, high-risk early breast cancer to assist clinicians in their day-to-day practice, and we review clinically relevant topics of dosing, side effect management, sequencing and optimal timing for initiation, and patient selection.

Real-world Efficacy and Safety of Low-Dose Abiraterone With Food and Standard-Dose Abiraterone in De Novo Metastatic Hormone-Sensitive Prostate Cancer: A Retrospective Analysis.

BACKGROUND: The standard treatment for de novo metastatic hormone-sensitive prostate cancer (mHSPC) involves androgen deprivation therapy (ADT) combined with next-generation hormonal agents and/or docetaxel. While the standard dose (STD) of abiraterone is 1,000 mg administered while fasting, recent evidence suggests that a low dose (LOW) of 250 mg taken with a low-fat meal may achieve comparable pharmacokinetic outcomes. OBJECTIVES: This study aimed to evaluate the failure-free survival (FFS) and safety of LOW and STD in de novo high-risk mHSPC patients. MATERIALS AND METHODS: We conducted a retrospective analysis of males with de novo high-risk mHSPC treated with ADT plus abiraterone (250 mg with a low-fat meal or 1000 mg fasting) at the Vietnam National Cancer Hospital from January 2019 to May 2024. The primary endpoint was FFS, assessed using Kaplan-Meier and multivariate Cox regression analyses. RESULTS: The study included 183 patients, with 91 in the LOW group and 92 in the STD group. The rates of patients who achieved undetectable PSA (PSA < 0.2 ng/ml) were 52.7% in the LOW group and 47.8% in the STD group. The median time to undetectable PSA was 6.9 months in the LOW group and 6.4 months in the STD group. The median overall FFS was 28.1 months (95% CI: 21.1 to 35.0) in the LOW group and 25.4 months (95% CI: 15.5 to 35.3) in the STD group (P = .286). Multivariate analysis indicated that visceral metastases and detectable PSA (PSA ≥ 0.2 ng/ml) were significant negative predictors of FFS in both groups. The incidence of grade 3 and grade 4 adverse events was similar between the LOW group and the STD group. CONCLUSIONS: The LOW group and STD group showed effectiveness and safety in de novo high-risk mHSPC. The use of low-dose abiraterone in de novo mHSPC can significantly reduce treatment costs.

Magnetic Resonance Image Radiomic Reproducibility: The Impact of Preprocessing on Extracted Features from Gross and High-Risk Clinical Tumor Volumes in Cervical Cancer Patients before Brachytherapy.

Background: Radiomic feature reproducibility assessment is critical in radiomics-based image biomarker discovery. This study aims to evaluate the impact of preprocessing parameters on the reproducibility of magnetic resonance image (MRI) radiomic features extracted from gross tumor volume (GTV) and high-risk clinical tumor volume (HR-CTV) in cervical cancer (CC) patients. Methods: This study included 99 patients with pathologically confirmed cervical cancer who underwent an MRI prior to receiving brachytherapy. The GTV and HR-CTV were delineated on T2-weighted MRI and inputted into 3D Slicer for radiomic analysis. Before feature extraction, all images were preprocessed to a combination of several parameters of Laplacian of Gaussian (1 and 2), resampling (0.5 and 1), and bin width (5, 10, 25, and 50). The reproducibility of radiomic features was analyzed using the intra-class correlation coefficient (ICC). Results: Almost all shapes and first-order features had ICC values > 0.95. Most second-order texture features were not reproducible (ICC < 0.95) in GTV and HR-CTV. Furthermore, 20% of all neighboring gray-tone difference matrix texture features had ICC > 0.90 in both GTV and HR-CTV. Conclusion: The results presented here showed that MRI radiomic features are vulnerable to changes in preprocessing, and this issue must be understood and applied before any clinical decision-making. Features with ICC > 0.90 were considered the most reproducible features. Shape and first-order radiomic features were the most reproducible features in both GTV and HR-CTV. Our results also showed that GTV and HR-CTV radiomic features had similar changes against preprocessing sets.

A predictive risk-scoring model for survival prognosis of multiple myeloma based on gain/amplification of 1q21: Experience in a tertiary hospital in South-Western China.

BACKGROUND: Chromosomal 1q gains and amplifications (+1q21) are frequently observed in patients with newly diagnosed multiple myeloma (NDMM). However, the interpretation of the high-risk (HR) prognostic implications stemming from 1q21 abnormalities remain challenging to implement effectively. METHODS: In a comprehensive analysis of 367 consecutive patients with symptomatic MM, we assessed the prognostic significance of +1q21 using FISH with a threshold of 7.4%. The patient cohort was randomly divided into a training set (66.5%, n = 244) and a validation set (33.5%, n = 133). A multivariate Cox regression analysis was conducted to identify significant prognostic factors associated with PFS. Weight scores were assigned to each risk factor based on the ß-value of the corresponding regression coefficient. A predictive risk-scoring model involving +1q21 was then developed, utilizing the total score derived from these weight scores. The model's discriminative ability was evaluated using the AUC in both the training and validation sets. Finally, we compared the performance of the +1q21-involved risk with the established R-ISS and R2-ISS models. RESULTS: Upon initial diagnosis, 159 patients (43.32%) exhibited +1q21, with 94 (59.11%) having three copies, referred to as Gain(1q21), and 65 (40.89%) possessing four or more copies, referred to as Amp (1q21). Both were significantly linked to a reduced PFS in myeloma (p < 0.05), which could be effectively mitigated by ASCT. The +1q21-involved risk model, with an AUC of 0.697 in the training set and 0.725 in the validation set, was constructed including Gain(1q21), Amp(1q21), no-ASCT, and TP53 deletion. This model, termed the ultra-high-risk (UHR) model, demonstrated superior performance in predicting shorter PFS compared to the R-ISS stage 3 and R2-ISS stage 4. CONCLUSION: The UHR model, which integrates the presence of +1q21 with no-ASCT and TP53 deletion, is designed to identify the early relapse subgroup among patients with +1q21 in NDMM.

Dose compliance of estramustine phosphate in neoadjuvant chemohormonal therapy combined with degarelix acetate predicts the biochemical recurrence in patients with very high-risk prostate cancer who underwent robot-assisted radical prostatectomy.

OBJECTIVES: The objective of this study is to evaluate the safety and efficacy of neoadjuvant degarelix acetate and low-dose estramustine phosphate for high-/very high-risk prostate cancer. METHODS: Overall, 187 patients diagnosed with National Comprehensive Cancer Network high-/very high-risk cTanyN0M0 localized prostate cancer who consented to undergo robot-assisted radical prostatectomy after receiving neoadjuvant chemohormonal therapy for 6 months were prospectively enrolled between December 2017 and March 2023. Adverse events, perioperative and histopathological outcomes, and biochemical recurrence-free survival rates were examined. Survival analysis compared the estramustine phosphate completion and reduction groups. RESULTS: Thirty-six patients discontinued neoadjuvant therapy in <5 months owing to adverse events (n = 34) or other reasons (n = 2). Eleven were excluded for being in the postoperative castration range. Of the 140 patients who underwent surgery, 124 continued with two tablets of estramustine phosphate and 16 with one tablet. Overall, 82 patients were very high-risk. Histopathological outcomes were significantly worse in the very high-risk group than those in the high-risk group. Very high-risk status and estramustine phosphate reduction were significant factors in biochemical recurrence in multivariate analysis. The biochemical recurrence-free survival rate in very high-risk patients was significantly lower in the estramustine phosphate dose reduction group than in the completion group but not significant in high-risk patients. Major adverse events were anemia (n = 174), elevated transaminase levels (n = 68), and deep vein thrombosis (n = 24). Severe adverse events included acute coronary syndrome (n = 4) and pulmonary embolism (n = 3). CONCLUSIONS: Dose compliance with estramustine phosphate predicted biochemical recurrence in patients with very high-risk prostate cancer undergoing robot-assisted radical prostatectomy with neoadjuvant chemohormonal therapy.

Risk-reducing surgeries for breast cancer in Brazilian patients undergoing multigene germline panel: impact of results on decision making.

PURPOSE: To assess the behavior change of high-risk breast cancer patients regarding the intention to undergo risk-reducing mastectomies (RRM) before and after genetic testing results and to identify the main influencing factors in decision-making. METHODS: Prospective cohort study conducted between November 2021 and October 2022 with women under follow-up at the high-risk outpatient clinic of the State University of Campinas (UNICAMP). Patients were referred for genetic testing, followed by counseling according to the test result. RESULTS: A total of 373 women were included. In the pre-genetic testing analysis, 54.1% of patients intended to undergo RRMs. After testing, 42.2% opted for the procedure. Behavior change occurred in 26.2%, mainly from "yes" to "no/don't know" (72,6%) (p < 0.001). The genetic test result was positive (LPV or PV) in 29.7% of patients. Among the 90 patients with positive results, 62 (68.9%) agreed to RRM, while 22 (24.4%) remained unwilling to accept RRM, regardless of the positive test. Significant influencing factors for behavior change pre- and post-genetic testing (in favor of surgery) in multivariate analysis were: positive genetic test result (OR 2.94, p < 0.001), personal cancer history (OR 2.7, p = 0.008), and ages between 40 and 49 years (OR 2.07, p = 0.008) and ≥ 50 years (OR 3.47, p < 0.001). CONCLUSION: In a Brazilian population at high-risk for breast cancer and users of the public health system, it was observed that most desired RRM, however, when genetic testing and counseling were performed, behavior change was observed, especially when the result was positive.

Does the absence of breast arterial calcification (BAC 0) rule out severe coronary artery disease? A computed tomography angiography study.

Background: Cardiovascular risk (CV)-stratification in females is challenging, and current models miss a high proportion at-risk. Breast arterial calcifications (BAC) are independent prognosticators, but their interaction with the coronary artery disease profile by computed tomography (CT) is controverse, and the role of BAC 0 unclear. Objective: to investigate the interaction of BAC with coronary CT outcomes (CAC score, coronary stenosis severity and high-risk plaque (HRP). Methods: Consecutive patients referred to mammography (MG) and coronary CTA for clinical indications within 1 year were included. Three different age groups were compared (<55 years;55-65 years;>65 years). Results: 443 patients were included. There were significant age differences for the prevalence of BAC 0 (p<0.001), BAC 0/CAC>300 AU (p=0.0023) and obstructive disease (>50% stenosis)(p=0.0048) but not for high-risk-plaque (HRP)(p=0.4905). High CAC (>300 AU) was present in only 0.82% of females with BAC 0 in less than 55 year, but significantly more often in those above 65 years (p=0.0004;OR=16.58:95% CI: 2.829-361.7) and 55 years with 12.1% and 8.4%. Obstructive coronary disease (>50% stenosis) in BAC 0 was present in 18.2%; with age-dependent differences (10.7% vs 14.7% vs 29.9%) (p=0.0003). The correlation between BAC, CAC and CADRADS was weak (r=0.246 and r=0.243, p<0.001). There was no association of BAC with HRP. Conclusion: BAC 0 rules out severe CAC >300AU in females <55 years only, but not in those above 55 years- with adherent implications for primary prevention. However, BAC 0 does not to rule out obstructive disease and high-risk plaques in symptomatic patients among all age groups.
