Background: Breast cancer neoadjuvant chemotherapy (NACT) allows for assessing tumor sensitivity to systemic treatment, planning adjuvant treatment and follow-up. However, a sufficiently large number of patients fail to achieve the desired level of pathological tumor response while optimal early response assessment methods have not been established now. In our study, we simultaneously assessed the early chemotherapy-induced changes in the tumor volume by ultrasound (US), the tumor oxygenation by diffuse optical spectroscopy imaging (DOSI), and the state of the tumor vascular bed by Doppler US to elaborate the predictive criteria of breast tumor response to treatment.

In recent years, Raman spectroscopy has been used to study biological tissues. However, the analysis of experimental Raman spectra is still challenging, since the Raman spectra of most biological tissue components overlap significantly and it is difficult to separate individual components. New methods of analysis are needed that would allow for the decomposition of Raman spectra into components and the evaluation of their contribution.

Pathological tortuosity of the internal carotid artery ranks next to atherosclerosis amongst causes leading to development of ischaemic strokes. In some patients pathological tortuosity of the internal carotid artery is combined with pathological kinking of the common carotid artery. Existing methods of surgical treatment for such concomitant pathology include stegewise elimination of kinking of the internal then common carotid artery, with two anastomoses sequentially formed, thus increasing the overall duration of arterial cross-clamping an prolonging cerebral ischaemia.

The authors describe a clinical case of a patient with metastatic basal cell carcinoma and secondary resistance to vismodegib. A mutation of unknown clinical significance was found in the gene encoding the transmembrane receptor protein Smoothened (SMO) protein, which suggests a defect in the Sonic Hedgehog (SH) pathway and may cause tumor resistance to the prescribed drug. Comprehensive genomic profiling and analysis have been used to diagnose the tumor.

Characteristics of Early-Onset vs Late-Onset Colorectal Cancer: A Review.

JAMA Surg

September 2021

Centre for Colorectal Disease, St Vincent's University Hospital, Dublin, Ireland.

Article Synopsis
  • The incidence of early-onset colorectal cancer (diagnosed in individuals under 50) is on the rise globally, with distinct clinical and molecular characteristics compared to late-onset cases.
  • Factors contributing to this increase may include diet, obesity, antibiotic use, and changes in gut microbiome, with most cases occurring sporadically rather than being genetically inherited.
  • There is a need for tailored preventive and therapeutic approaches for early-onset colorectal cancer, as younger patients often present with more severe disease stages but similar outcomes to older patients after treatment.
