RESUMO

The transformation of acute promyelocytic leukemia (APL) from an often fatal to highly curable cancer with long-term survival exceeding 90% is one of the greatest and most inspiring successes in oncology. A deeper understanding of the pathogenesis of APL heralded the introduction of highly effective therapies targeting the mutant protein that drives the disease, leading to the chemotherapy-free approach to cure almost all patients. In this review, we discuss the paradigm of treatment of APL in 2023, reinforce the high risk of early death without prompt initiation of treatment at first clinical suspicion, and dedicate a special focus to novel agents and future directions to improve cure rates and quality of life in patients affected by APL.

RESUMO

PURPOSE: To assess the trends of neoadjuvant chemotherapy (NAC) use since its introduction in our practice pathway in patients with cT2 + bladder cancer over a 20-year period. METHODS: This is a retrospective review of patients with cT2 + bladder cancer who underwent RC between 01/01/1998 and 01/01/2018 that aimed to evaluate the trends of NAC use and associated after implementation of a multidisciplinary treatment pathway. Cohorts were stratified into eras: pre-NAC (1998-2007) to NAC eras (2008-2018). Univariate analysis was conducted using Chi-squared test and Kaplan-Meier estimates were used to evaluate survival. RESULTS: In 904 total patients who underwent RC, there were 493 with cT2 + UCC disease. The rate of NAC peaked at 84.2% in the most recent year of analysis in all patients and was 100% in cT2 + patients eligible for NAC. There was an increased rate of complete response (downstage to pT0) from 8.7% to 15.8% (p = 0.018) between the two eras. Unadjusted survival analysis revealed improved overall survival (OS) between eras with 5-year OS 53.2% vs. 42.7% and 10-year OS 42.7% vs. 26.4% in the NAC vs. pre-NAC cohorts, respectively (p = 0.016). CONCLUSIONS: In this review of 20 years of experience, we report a dramatic rise in the use of NAC after adoption of a multidisciplinary pathway that is associated with expected survival benefits.

RESUMO

OBJECTIVE: To compare the perioperative and oncologic outcomes associated with open radical nephrectomy with tumor thrombus (O-RNTT) vs robot assisted radical nephrectomy with tumor thrombus (RA-RNTT). Renal cell carcinoma with venous tumor thrombus has traditionally been managed through an open surgical approach. The robot assisted approach may offers improved perioperative outcomes compared to open, but there are few studies comparing these 2. METHODS: We analyzed patients with renal cell carcinoma and inferior vena cava tumor thrombus between 1998 and 2018, comparing perioperative and oncologic outcomes of these patients with Level I and Level II thrombus. Cohorts were stratified by surgical approach: O-RNTT vs RA-RNTT. Univariate analysis was conducted using chi-squared test and t tests when appropriate. Kaplan-Meier estimates were used to evaluate survival. RESULTS AND LIMITATION: Twenty-seven patients were in the O-RNTT group, and 24 in the RA-RNTT group. Patients in the RA-RNTT group, compared to the O-RNTT group, demonstrated shorter length of stay (3 vs 7 nights, P = .03), lower estimate blood loss (450 vs 1800 mL, P <.01), and lower transfusion rate (21% vs 82%, P <.01). The RA-RNTT group had 26% fever complications compared to the open (17% vs 43%, P <.01). There was no significant difference in estimated overall survival or recurrence-free survival between the O-RNTT and RA-RNTT groups. CONCLUSION: RA-RNTT produced a shorter length of stay, less transfusions, and a lower rate of complications with no significant difference in overall survival.

RESUMO

BACKGROUND: Two digital mammography systems, based on different physical concepts, have been introduced in the last few years namely the full-field digital mammography (FFDM) system and computed radiography-based mammography using digital storage phosphor plate (DSPM). AIMS: The objective of this study was to compare the image quality for DSPM and FFDM using a grading scale based on previously published articles. MATERIALS AND METHODS: This comparative diagnostic study was done for 5-month duration at the Breast Clinic. The system used was the Lorad Selenia FFDM system and the Mammomat 3000 Nova DSPM system. The craniocaudal and mediolateral oblique projections were done on both breast on 58 asymptomatic women using both DSPM and FFDM. The mammograms were evaluated for eight criteria of image quality: Tissue coverage, compression, exposure, contrast, resolution, noise, artifact, and sharpness by two independent radiologists. STATISTICAL ANALYSIS: Wilcoxon Signed Rank Test and Weighted Kappa. RESULTS: FFDM was rated significantly better (P < 0.05) for five aspects: Tissue coverage, compression, contrast, exposure, and resolution and equal to DSPM for sharpness, noise, and artifact. CONCLUSION: FFDM was superior in five aspects and equal to DSPM for three aspects of image quality.
