The application of circulating tumor cells (CTCs) as diagnostic and prognostic markers in oncology is gaining increasing importance in clinical practice. Currently, various methods exist for detecting CTCs in patients' biological fluids. This systematic review aimed to compare the efficacy of different techniques for isolating and detecting CTCs from blood, against the FDA-cleared CellSearch® technology, in breast cancer patients.

- - This case study highlights a rare instance of colorectal cancer spreading to the fallopian tube and uterus in a 61-year-old woman, who initially underwent surgery for stage pT3N0M0 colorectal cancer.
- - After a six-month follow-up without issues, she experienced a recurrence and started chemoradiotherapy, leading to a full response.
- - Eventually, pelvic pain led to imaging that revealed a mass in her fallopian tube and uterus, resulting in surgery that confirmed the metastasis of her rectal cancer.
Aim To evaluate the incidence of prolonged corrected QT interval (QTc) by remote single-channel electrocardiogram (ECG) monitoring in primary oncological patients with elective polychemotherapy (PCT).Material and methods This study included 49 oncological patients with elective PCT. A single-channel portable CardioQVARK electrocardiograph was used to record single-channel, one-lead ECG between the first and second courses of PCT.

The purpose of the blind clinical study was the assessment of the novel diagnostic chemiluminescent CLIA-CA-62 assay for early-stage breast cancer detection.
Methods: Blind serum samples of 196 BC patients with known TNM staging, 85% with DCIS, Stage I & IIA, and 73 healthy control subjects were analyzed with the CLIA-CA-62 and CA 15-3 ELISA assays.
Preliminary low-dose photodynamic exposure to skin cancer with chlorin e6 photosensitizer.
Photodiagnosis Photodyn Ther
June 2022
Background: The study aimed to investigate the chlorin e6 photosensitizer distribution in the tumor and tumor border (5 mm) during low-dose photodynamic treatment and to increase the effectiveness of the therapy for skin neoplasms.
Methods: Sensitized boundaries of neoplasms were evaluated by video fluorescence imaging. The study of changes in the chlorin e6 distribution before/after photodynamic therapy and in the process of low-dose photodynamic exposure was carried out by the method of spectral fluorescence diagnostics.
