Special Issue Information

Dear Colleagues,

Colorectal carcinoma is one of the most frequent malignant cancers of the gastrointestinal tract. Each year, 1.8 million new cases of this cancer are identified worldwide, and the global mortality amounts to 862,000 deaths. Despite the impressive development of medicine, so far, it has not been possible to find a fully effective method for treating this and other cancers. Numerous studies have shown that among the patients who have been treated only surgically, there is the highest risk of recurrence and metastatic changes. Therefore, the methods of surgical treatment are usually part of combination therapy that additionally includes radiotherapy and chemotherapy. Unfortunately, in the process of defending the malignant cells against the activity of cytotoxic drugs used in chemotherapy, many signal pathways are involved, which leads to the insufficient effectiveness of the pharmacological treatment. New compounds that could manifest potential anticancer activity are therefore constantly studied. Because of the multifactorial character of cancers, searching for an effective therapeutic substance is oriented towards the so-called multifunctional drugs, which at the same time affect several biological targets.

As a guest editor, I invite you to contribute your latest research findings or updated reviews to this Special Issue focused on pharmacotherapy for colorectal cancer and the implementation of combination therapies that entail the combined use of two or more cancer-cell-growth inhibitors. The simultaneous use of many active substances can increase the risk of side-effects, but the skillful use of the interactions that occur among them allows increasing their effectiveness and the safety of the therapy.

Aberrant expression of genes contributes to the chemoresistance of colorectal cancer (CRC) treatment. This study aimed to identify genes associated with the chemoresistance of oxaliplatin-based chemotherapy in CRC patients and to construct a signature. Oxaliplatin resistance-related genes were screened by analyzing the gene profiles of cell lines and tissue samples that underwent oxaliplatin-based treatment. Oxaliplatin resistance-related genes were used to establish a signature. The association of the signature had clinical significance, so the prognostic value of the signature was analyzed. Independent cohorts and CRC cell lines were used to validate the value of the gene signature and the oxaliplatin-resistant genes. There were 64 oxaliplatin resistance-related genes identified after overlapping the genes from the dataset of oxaliplatin-treated CRC cells and the dataset of patients treated with oxaliplatin-based chemotherapy. A gene signature based on five oxaliplatin resistance-related genes was established. This gene signature effectively predicted the prognosis of CRC patients who underwent chemotherapy. No significant associations were found between the gene mutations and survival of the patients; however, two genes were associated with microsatellite instability status. Two external independent cohorts and CRC cell line experiments validated the prognostic values of the signature and expression of the genes after oxaliplatin treatment. In conclusion, the oxaliplatin resistance-related gene signature involving five genes was a novel biomarker for the prediction of the chemotherapy response and prognosis of CRC patients who underwent oxaliplatin-based chemotherapy.
