CONCLUSION: 18F FDG PET-CT predicted the response with greater accuracy than CT or clinical examination. Hence it can be used to identify non responders early in the course and alternate treatment can be offered to patients. PMID: 31983170 [PubMed - in process]

ConclusionsAchieving pCR after neoadjuvant chemotherapy was associated with clinically meaningful improvements in survival parameters in a real-world setting. The cumulative data support pCR as a valid surrogate endpoint in both clinical trials and population-based settings.

Contributors : Alexey I Kalinkin ; Alexander S TanasSeries Type : Methylation profiling by high throughput sequencingOrganism : Homo sapiensDespite the advantages of neoadjuvant chemotherapy (NACT), associated toxicity is a serious concern and close monitoring of the response of the patients to NACT is required. Thus, prediction of treatment response is imperative to avoid exposure of potential non-responders to deleterious side effects of NACT. We have performed genome-wide analysis of DNA methylation by XmaI-RRBS and selected CpG dinucleotides differential methylation of which discriminates BC samples with different sens...

The objective was to compare post-operative complication rates among patients treated with partial mastectomy (PM), unilateral mastectomy (UM), and bilateral mastectomy (BM) after NAC.Study design398 patients with breast cancer who had NAC from 2008 to 2016 were identified from a prospectively maintained database. The primary outcome measure was 30-day post-operative morbidity.Results125 patients (31.4%) underwent PM, 107 patients (26.9%) UM, and 166 (41.7%) BM. There was no significant difference among the 3 groups with respect to histology (ductal: 96.0% PM, 88.8% UM, 92.6% BM, p = 0.161). Groups were similar with re...

Conclusions: This is the third case of primary ES of the petroclival bone to be reported in the literature. In this patient, management consisted of surgical incisional biopsy followed by adjuvant radiation and chemotherapy. Knowledge and awareness of this type of tumor is important for the skull base surgeon. PMID: 31966925 [PubMed]

YKL-39 belongs to the evolutionarily conserved family of Glyco_18-containing proteins composed of chitinases and chitinase-like proteins. Chitinase-like proteins (CLPs) are secreted lectins that lack hydrolytic activity due to the amino acid substitutions in their catalytic domain and combine the functions of cytokines and growth factors. One of the major cellular sources that produce CLPs in various pathologies, including cancer, are macrophages. Monocytes recruited to the tumor site and programmed by tumor cells differentiate into tumor-associated macrophages (TAMs), which are the primary source of pro-angiogenic factors...

Objective: Changes in the number of various tumor-infiltrating lymphocytes (TILs) and degrees of vascular normalization in breast cancer (BC) patients after neoadjuvant chemotherapy (NAC) were analyzed to screen key factors that can predict the prognosis.Methods: HE-stained sections were used to assess the degree of TILs infiltration; immunohistochemically stained sections were used to assess the infiltration of CD8+, CD4+, FOXP3+ Tregs and the expression of PD-L1; immunofluorescence-stained sections were used to assess the microvessel density (MVD) and microvessel pericyte coverage index (MPI). The expression of them befo...
