ADJUVANT CHEMOTHERAPY IN THE TREATMENT OF PATIENTS WITH GALLBLADDER CANCER

Abstract

Among the malignant neoplasms of the hepatobiliary zone, gallbladder cancer (GBC) is rare. The incidence of GBC is highest in patients over 65 years of age. In the early stages GBC rarely has clinical manifestations, and often occurs under the guise of other gastroenterological diseases, and is often an accidental finding. Since GBC tends to show high dissemination, at the time of diagnosis, almost every second patient has an advanced form of the disease that is not the subject to surgical treatment. Most authors tend to believe that the use of combined treatment of GBC (extended resection and adjuvant chemotherapy) significantly increases the survival rate of patients. Currently, about 1/3 of patients receive adjuvant chemotherapy in the treatment of GBC. This is due to a small number of prospective randomized trials. Today, most experts recognize that surgery is the only treatment that can be performed in patients with early stages of prostate cancer. At the same time, a reduction in the risk of complications and a large percentage of five- and ten-year survival are achieved. Traditional cholecystectomy can be used to treat stage 1a PCa, this is possible if PC is accidentally found during surgical treatment of GSD. Unfortunately, prostate cancer and bile ducts belongs to the group of malignant neoplasms, in which most patients are unable to perform radical surgical treatment due to for the rapid dissemination of the process. When determining the tactics of patient supervision, it is necessary to take into account the prognostic factors of overall survival in prostate cancer: the type of surgery, the patient's age and sex, the size of the tumor, the presence of metastases in the regional lymph nodes, the presence of adjuvant chemotherapy. There is still a dispute between specialists about the appointment of adjuvanted chemotherapy to patients after surgical treatment of prostate cancer. Many authors acknowledge that adjuvant chemotherapy plays a positive role in improving patient survival after surgery. RAD is recognized as a chemosensitive cancer. Several drugs are active in relation to RS, used for adjuvant chemotherapy: fluorouracil, gemcitabine, mitomycin, cisplatin, capecitabine, epirubicin, and oxaliplatin. This article provides an overview of current research that is aimed at studying the effectiveness of adjuvant chemotherapy in patients with verified GBC of various stages.
