(1) Background: There are no reliable and widely available markers of functional iron deficiency (FID) in cancer. The aim of the study was to evaluate the role of transferrin (Tf) as a marker of cancer of the ovary (CrO) and related FID. (2) Methods: The study groups consisted of 118 patients with CrO and 69 control females. Blood serum iron status was determined on a Beckman Coulter AU (USA) analyzer. Tf quantification was performed by immunoturbidimetry. The relative contents of apo- and holo-Tf (iron-free and iron-saturated Tf, respectively) were determined in eight patients and a control female by immunochromatographic analysis based on the use of monoclonal single-domain antibodies (nanobodies). (3) Results: Four groups of patients with different iron statuses were selected according to ferritin and transferrin saturation values: absolute iron deficiency (AID) (n = 42), FID (n = 70), iron overload (n = 4), normal iron status (n = 2). The groups differed significantly in Tf values (p < 0.0001). Lower values of Tf were associated with FID. Furthermore, FID is already found in the initial stages of CrO (26%). Immunosorbents based on nanobodies revealed the accumulation of apo-Tf and the decrease in holo-Tf in patients with CrO. (4) Conclusions: Tf may be a promising tool for diagnosing both CrO and associated FID.

Purpose.We analyzed the frequency and severity of hematologic, hepatic and pancreatic toxicity during and after completion of neoadjuvant chemoradiotherapy in patients with gastric cancer.Material and methods. Phase II clinical trial was conducted to evaluate the efficacy of the combined modality treatment including neoadjuvant chemoradiotherapy followed by D2 gastrectomy for patients with locally advanced gastric cancer. The main inclusion criteria were: histologically verified gastric cancer, cT3-4N0, cT2-4N1-3; M0. Before starting neoadjuvant therapy, all patients underwent thoracic and abdominal CT and laparoscopy to exclude peritoneal carcinomatosis. A total dose of radiation therapy was 45 Gy (1 + 1.5 Gy/fraction/day with a 4–5 hour interval) concurrently with the modified CAPOX chemotherapy regimen. Gastrectomy or subtotal resection of the stomach was planned 4-6 weeks after the completion of chemoradiotherapy. The toxicity assessment of neoadjuvant chemoradiotherapy was performed using the NCI CTC scale, version 3.0. The assessment of hematological, hepatic and pancreatic toxicities was done.Results.Among the toxicity during and after completion of neoadjuvant chemoradiotherapy, thrombocytopenia, neutropenia and leukopenia (grade 1–2) were the most common, requiring no additional symptomatic therapy. Radiation therapy was completed in 45 (98 %) patients. Chemotherapy was completed in 42 (91 %) patients. The median time between the completion of chemoradiotherapy and surgery was 44 days. Surgery following chemoradiotherapy was performed in 100 % of patients, including R0 resection in 93 % of patients.Conclusion.Preoperative chemoradiotherapy was well tolerated by patients, could be completed in most cases and did not prevent subsequent surgical treatment.

The antioxidant effects of lignan - 7-hydroxymatiresinol as complementary therapy for gynecological diseases Relevance. The work is devoted to the study of the antioxidant effect of lignan - 7-hydroxymatairezinol in various gynecological diseases. Materials and methods. The study included 30 women taking lignan - 7-hydroxymatairezinol (in a dose of 30 mg/day for 60 days), which was conducted mini-invasive or surgical treatment. They studied the general antioxidant status and its enzymatic link before and after drug treatment. Results and conclusions. Comparative analysis of the results showed that the drug along with antioxidant has anti-inflammatory action with good portability, which allowed him to recommend for use as a complementary therapy for gynecological diseases various nature: malignant neoplastic diseases, inflammatory diseases, etc), especially after surgery.
