Lymphadenectomy in elderly/high risk patients: Should it be different?

The global aging of population will lead a greater number of elderly patients to undergo surgical procedure in a near future. Concerning gastric cancer, the impact of lymphadenectomy on survival has been demonstrated in RCTs, and extended lymphadenectomy is now considered as gold standard of treatment in non-early tumors. However, the role of age as a prognostic factor and the benefit of extended surgery in elderly/high-risk patients are not clearly defined yet. From our revision of literature, it seems that surgery for gastric cancer may have a further tailorization, considering not only the stage of disease, but also patients' age and comorbidities

N staging system: Tumor-node-metastasis and future perspectives

The correct staging of disease, with an exact definition of the extent of cancer at the diagnosis, is crucial in the planning of a specific treatment and in the assessment of real chances of cure. Cancer staging systems are expected to be accurate in the description of the severity of a patient's tumor on the basis of the extent of the primary neoplasm and of its spread, thus giving clinician tools to estimate prognosis and providing objective parameters to compare groups of patients in clinical studies. This last point is of wide importance in evaluating successful treatment strategies in oncology, and this is one of the issues that contributed to the development of stage-adapted therapies

Seventh tumor-node-metastasis staging of gastric cancer: Five-year follow-up

Seventh tumor-node-metastasis (TNM) classification for gastric cancer, published in 2010, introduced changes in all of its three parameters with the aim to increase its accuracy in prognostication. The aim of this review is to analyze the efficacy of these changes and their implication in clinical practice. We reviewed relevant Literature concerning staging systems in gastric cancer from 2010 up to March 2016. Adenocarcinoma of the esophago-gastric junction still remains a debated entity, due to its peculiar anatomical and histological situation: further improvement in its staging are required. Concerning distant metastases, positive peritoneal cytology has been adopted as a criterion to define metastatic disease: however, its search in clinical practice is still far from being routinely performed, as staging laparoscopy has not yet reached wide diffusion. Regarding definition of T and N: in the era of multimodal treatment these parameters should more influence both staging and surgery. The changes about T-staging suggested some modifications in clinical practice. Differently, many controversies on lymph node staging are still ongoing, with the proposal of alternative classification systems in order to minimize the extent of lymphadenectomy. The next TNM classification should take into account all of these aspects to improve its accuracy and the comparability of prognosis in patients from both Eastern and Western world

Neoadjuvant chemotherapy in locally advanced gastric cancer: what to avoid. Preliminary analysis of a consecutive series of patients

The role of neoadjuvant (NAD) chemotherapy (CHT) in patients with locally advanced gastric cancer (LAGC) is validated. However, some important limitations emerged from the literature, including patient selection, quality of surgery, and pathologic response evaluation. Neoadjuvant CHT for LAGC has been evaluated with a focus on safety and efficacy of the preoperative approach in terms of patient compliance, surgical outcomes, and pathologic response

Prognostic Indicators in Stage IV Surgically Treated Gastric Cancer Patients: A Retrospective Multi-Institutional Study

Introduction: The role of gastric resection in treating metastatic gastric adenocarcinoma is controversial. In the present study, we reviewed the short- and long-term outcomes of stage IV patients undergoing surgery. Methods: A retrospective review was conducted that assessed patients undergoing elective surgery for incurable gastric carcinoma. Short- and long-term results were evaluated. Results: A total of 122 stage IV gastric cancer patients were assessed. Postoperative mortality was 5.7%, and the overall rate of complications was 35.2%. The overall survival rate at 1 and 3 years was 58 and 19% respectively; the median survival was 14 months. Improved survival was observed for the factors age less than 60 years (p = 0.015), site of metastases (p = 0.022), extended lymph node dissection (p = 0.044), absence of residual disease after surgery (p = 0.001), and administration of adjuvant chemotherapy (p = 0.016). Multivariate analysis showed that residual disease and adjuvant chemotherapy were independent prognostic factors. Conclusions: The results of this study suggest that surgery combined with systemic chemotherapy in selected patients with stage IV gastric cancer can improve survival
