Changes in the tumor oxygenation but not in the tumor volume and tumor vascularization reflect early response of breast cancer to neoadjuvant chemotherapy

Mikhail V. Pavlov, Anna P. Bavrina, Vladimir I. Plekhanov, German Yu. Golubyatnikov et autres

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 …

Follicular lichen ruber planus induced by occupational factors

M. V. Zor'kina, M.S. Neznahina, Д. А. Давыдова

Актуальность вопросов, касающихся диагностики и терапии красного плоского лишая, обусловлена его довольно высокой распространенностью, клиническим сходством с другими дерматозами и большой вероятностью возникновения нетипичных высыпаний. В типичных случаях заболевание характеризуется появлением на коже симметричных плоских, синевато-красных полигональных папул. При наличии у больного …

In vivo multimodal optical imaging of dermoscopic equivocal melanocytic skin lesions

Vadim V. Elagin, Ekaterina V. Gubarkova, O.E. Garanina, Д. А. Давыдова et autres

There is a wide range of equivocal melanocytic lesions that can be clinically and dermoscopically indistinguishable from early melanoma. In the present work, we assessed the possibilities of combined using of multiphoton microscopy (MPM) and optical coherence angiography (OCA) for differential diagnosis …

Accurate detection of white matter tracts: mapping of human brain eloquent areas with cross-polarization optical coherence tomography

Elena B. Kiseleva, Konstantin S. Yashin, Alexander A. Moiseev, Д. А. Давыдова et autres

Optical coherence tomography (OCT) is a promising method for clarifying the boundaries of the infiltrative brain tumors within surrounding white matter. Since gliomas often tend to grow close to eloquent brain areas, the question of the proximity of the tumor to white …
