Association of urinary and plasma DNA in early breast cancer patients and its links to disease relapse

ConclusionUrinary DNA offers a unique opportunity to glimpse upon dynamic changes in early breast cancer. Our results demonstrated good correlation to plasma DNA and post monitoring of cancer patients to identify individuals susceptible to a high risk of relapse. This potentially allows for early intervention such as adjuvant chemotherapy to be administered to better manage these patients.

We report the largest series of IMCs treated with NAC, and report a characteristic, but not well recognised, pattern of pathological response. Methods and resultsOur series included seven patients with IMC treated with NAC. Three patients presented with locally advanced disease, three patients had tumours that were HER‐2/neu‐positive, and four patients had tumours with admixed mucinous and micropapillary features. Clinical and imaging assessment of response showed persistent and, in some cases, progressive disease, despite evidence of significant pathological response in these cases. Pathological assessment after NAC d...

CONCLUSIONS: This study confirmed the therapeutic impact of lapatinib, trastuzumab, and paclitaxel therapy for each ER- and ER+ subgroup of HER2+ patients. Development of further strategies and tools is required, particularly for luminal HER2 disease. PMID: 29445928 [PubMed - as supplied by publisher]

ConclusionPatients that achieved a pCR appeared less likely to present with skeletal metastases and more frequently presented with CNS metastases as first site of distant relapse, even after adjustment for molecular subtypes.

ConclusionsBoth CTCs and DTCs are detectable after NACT. As we could not show a significant relationship between CTC detection, DTC detection and pCR, all three methods may provide independent information regarding treatment response. Since we were unable to show a significant impact on survival, larger prospective studies that include CTCs and DTCs are needed. These trials should include the molecular characterization of primary tumor tissue, CTCs and DTCs to determine whether these cells are independent subpopulations of malignant cell clones.

By BISHAL GYAWALI, MD Why conduct post approval studies at all? Atezolizumab previously received accelerated approval in second-line metastatic or advanced urothelial cancer based on response rates from a single arm trial. The results of post approval confirmatory phase 3 are now published and demonstrate that atezolizumab did not improve survival versus chemotherapy (11.1 v 10.6 months, HR 0.87, p = 0.41). The concept of accelerated approval is to grant early and conditional approval and access to drugs in diseases of unmet need, and that the decision to fully approve or revoke be made based ...

AbstractPurposeThe purpose of this two-cohort Phase II trial was to estimate the pathologic complete response (pCR: ypT0/is ypN0) rate when trastuzumab plus pertuzumab are administered concurrently during both the taxane and anthracycline phases of paclitaxel and 5-fluorouracil/epirubicin/cyclophosphamide (FEC) neoadjuvant chemotherapy.MethodsThe pCR rates were assessed separately in hormone receptor (HR) positive and negative cases following Simon ’s two-stage design, aiming to detect a 20% absolute improvement in pCR rates from 50 to 70 and 70 to 90% in the HR-positive and HR-`negative cohorts, respectively.Results...

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...
