Gastric cancer is one of the most common cause of cancer related deaths worldwide which results in malignant tumors in the digestive tract. The only radical treatment option available is surgical resection. Recently, the implementation of neoadjuvant chemotherapy resulted in 5-year survival rates of 95% for early gastric cancer. The main reason of treatment failure is that early diagnosis is minimal, with many patients presenting advanced stages. Hence, the greatest benefit of radical resection is missed. Consequently, the main therapeutic approach for advanced gastric cancer is combined surgery with neoadjuvant chemotherapy, targeted therapy, or immunotherapy. In this review, we will discuss the various treatment options for advanced gastric cancer. Clinical practice and clinical research is the most practical way of reaching new advents in terms of patients' characteristics, optimum drug choice, and better prognosis. With the recent advances in gastric cancer diagnosis, staging, treatment, and prognosis, we are evident that the improvement of survival in this patient population is just a matter of time.

Abstract BACKGROUND Neoadjuvant chemotherapy (NAC) with subsequent radical surgery has become a popular treatment modality for advanced gastric cancer (AGC) worldwide. However, the survival benefit is still controversial, and prognostic factors remain undetermined. AIM To identify clinical parameters that are associated with the survival of AGC patients after NAC and radical surgery and to establish a nomogram integrating multiple factors to predict survival. METHODS We reviewed the medical profiles of 215 AGC patients who received NAC and radical resection, and clinical parameters concerning NAC, surgery, pathological findings, and adjuvant chemotherapy were analyzed using a Cox regression model to determine their impact on survival. Based on these factors, a nomogram was developed and validated. RESULTS The overall 1-year and 3-year survival rates were 85.8% and 55.6%, respectively. Younger age (< 60 years old), increased examined lymph nodes (exLNs), successful R0 resection, achievement of pathological complete response (pCR), and acceptance of adjuvant chemotherapy were positive predictors of survival. The concordance statistic of the established nomogram was 0.785. The model showed an ideal calibration following internal bootstrap validation. CONCLUSION A nomogram predicting survival after NAC and surgery was established. Since this nomogram exhibited satisfactory and stable predictive power, it can be inferred that this it is a practical tool for predicting AGC patient survival after NAC and radical surgery.

Locally Advanced Gastric Cancer

The purpose of the study was a systemic literature review on data regarding the efficacy, safety and prospects for the use of adjuvant chemotherapy for locally advanced gastric cancer.Material and Methods. The study contained a thorough literary analysis of the results of international studies on the use of preoperative and postoperative chemotherapy for locally advanced gastric cancer. Relevant sources were searched in Medlin and Cochrane Library databases, and publications from 2001 to 2019 were included. Of all the studies analyzed, 28 were used to write the systematic review.Results. The increase in survival rates was mainly achieved due to the use of a multimodal approach to the treatment of gastric cancer. The effectiveness of this approach, which combined surgery with chemotherapy or chemoradiotherapy, was proven in several large clinical studies. However, despite the large number of treatment options for locally advanced gastric cancer, there is still no single standard for the management of patients with this disease. One of the treatment options successfully practiced in a number of leading countries is the use of adjuvant chemo/chemoradiation therapy.Conclusion. Analysis of the literature data of the last 18 years has shown the high relevance of studies on adjuvant chemotherapy for gastric cancer and the need to continue further study of this problem.

Background. Neoadjuvant chemotherapy (NAC) with subsequent radical surgery has become a popular treatment modality for advanced gastric cancer (AGC) worldwide. However, the survival benefit is still controversial, and prognostic factors remain undetermined. Aim. To identify clinical parameters that are associated with the survival of AGC patients after NAC and radical surgery and to establish a nomogram integrating multiple factors to predict survival. Methods.

Based on these factors, a nomogram was developed and validated. Results. The overall 1-year and 3-year survival rates were 85.8% and 55.6%, respectively. Younger age (<60 years old), increased examined lymph nodes (exLNs), successful R0 resection, the achievement of pathological complete response (pCR), and acceptance of adjuvant chemotherapy were positive predictors of survival. The C-index of the established nomogram was 0.785. The area under receiver operating curve (ROC) at 1/3 years of prediction was 0.694/0.736, respectively. The model showed an ideal calibration following internal bootstrap validation. Conclusion. A nomogram predicting survival after NAC and surgery was established. Since this nomogram exhibited satisfactory and stable predictive power, it can be inferred that this is a practical tool for predicting AGC patient survival after NAC and radical surgery.

Gastric cancer is one of the most common cancers and a main cause of cancer-related death worldwide, since the majority of patients suffering of this malignancy are usually faced with a poor prognosis due to diagnosis at later stages. In order to improve treatment outcomes, the association of surgery with chemo and/or radiotherapy (multimodal therapy) has become the standard treatment for locally advanced stages. However, despite several treatment options currently available for management of these tumors, perioperative chemotherapy has been mainly accepted for the comprehensive therapeutic strategy including an appropriated D2-gastrectomy. This manuscript presents a (nonsystematic) critical review about the use of perioperative chemotherapy, with a special focus on the drugs delivery.
