Aim: To assess the safety and tolerability of subcutaneous (SC) trastuzumab (Herceptin) administered either with a single-use injection device (SID) or manually from a vial using a hand-held syringe.

Methods: The ESCAPE trial (NCT02194166) included 90 women aged 18 years or older with HER2-positive early breast cancer who underwent surgical treatment and completed (neo) adjuvant chemotherapy and radiotherapy (if indicated). Patients enrolled in the study were first subjected to 4 cycles of trastuzumab IV (8 mg/kg loading dose followed by 6 mg/kg maintenance dose, q3w) prior to being randomized into groups: [A] SC trastuzumab (fixed dose 600 mg, q3w) administered through a hand-held syringe followed by 7 cycles of SC trastuzumab administered with an SID or [B] the reverse sequence.

Classical Hodgkin lymphoma (cHL) is a malignancy characterized by the presence of Hodgkin and Reed-Sternberg (HRS) cells within a complex tumor microenvironment (TME). Despite advances in conventional therapies, a subset of cHL patients experience relapse or refractory disease, necessitating the exploration of novel treatment strategies. Chimeric antigen receptor T cell (CAR-T cell) therapy has emerged as a promising approach for the management of cHL, harnessing the power of genetically modified T cells to recognize and eliminate tumor cells.

Introduction: Cancer is a global health concern, with a significant impact on mortality rates. Despite advancements in targeted antitumor drugs, the development of new therapies remains challenging due to high costs and tumor resistance. The exploration of novel treatment approaches, such as combined chemotherapy, holds promise for improving the effectiveness of existing antitumor agents.

Background: Elevated β-tubulin levels are associated with resistance to a broad spectrum of drugs in different carcinomas and with poor prognosis of various epithelial cancers. 5-Fluorouracil (5-FU) is a widely used standard drug in chemotherapeutic regimens for colorectal cancer treatment, although the resistance to 5-FU is a major obstacle to successful therapy.

Aim: The aim of the study was to compare the invasive and adhesion properties and the expression levels of β-tubulin in a 5-fluorouracil (5-FU)-resistant colorectal cancer (CRC) cell line HCT116 and parental cells.

Evaluation of the efficacy of the combination of radical surgery, hyperthermic intraperitoneal chemotherapy (HIPEC), and adjuvant systemic chemotherapy (ACT) in reducing gastric cancer progression in patients with resectable serosa-invasive gastric cancer in a single institution. In 2015-2016, 19 patients with gastric cancer (stage IIB-IIIC) were included in the trial. The trial protocol comprised radical surgery, HIPEC (cisplatin 50 mg/m + doxorubicin 50 mg/m, 42 °C, 1 hour), and 1-8 cycles of ACT (oxaliplatin 100 mg/m administered on day 1 of each cycle and oral capecitabine 1000 mg/m (or tegafur 10-15 mg/kg) administered twice daily on days 1-14 of each cycle with an interval of 7 days between cycles).

Background: Reaching an acceptable participation rate in screening programs is challenging. With the objective of supporting the Belarus government to implement mammography screening as a single intervention, we analyse the main determinants of breast cancer screening participation.

Methods: We developed a discrete choice experiment using a mixed research approach, comprising a literature review, in-depth interviews with key informants (n = 23), "think aloud" pilots (n = 10) and quantitative measurement of stated preferences for a representative sample of Belarus women (n = 428, 89% response rate).

Aim: Base excision repair (BER) gene polymorphisms are known to play an independent role in predisposition to developing different cancers as well as to be associated with clinicopathological traits of the disease modifying its clinical outcomes. One of the underlying mechanisms is presumed to include interplay between BER gene polymorphisms and key mutational, epigenetic and chromosomal events in tumor tissues. The present study was aimed at elucidating potential gene-gene interaction and assessing their mutual effects in bladder cancer (BC).

Article Synopsis
  • After the Chernobyl disaster, researchers looked at health issues in kids exposed to radioactive Iodine-131, especially if they got other types of cancer besides thyroid cancer.
  • They studied about 12,000 people from Belarus who were under 18 when the disaster happened and followed them for 15 years to see if they got cancers like leukemia or lymphoma.
  • The results showed that there wasn't a big increase in these other cancers, but the researchers still think it’s important to keep checking on these people as they get older.
