Gastric Cancer 2013; 16:28-40. [PMID: 22467061 DOI: 10.1007/s10120-012-0148-3] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2011] [Accepted: 02/16/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND Gastric cancer is a global health problem accounting for 10% of all new cancer cases and 12% of all cancer deaths worldwide. Many clinical trials and meta-analyses have explored the value of neoadjuvant or adjuvant chemotherapy and radiation therapy in gastric cancer; however, these studies have produced conflicting results. The purpose of this guidance document was to determine whether patients with resectable gastric cancer should receive neoadjuvant or adjuvant therapy in addition to surgery. Outcomes of interest were overall survival, disease-free survival, and adverse events. METHODS A systematic review was undertaken to inform recommendations regarding neoadjuvant and adjuvant therapy in resectable gastric cancer in Ontario, Canada. MEDLINE and EMBASE databases, as well as American Society of Clinical Oncology (ASCO) annual meeting proceedings and American Society for Therapeutic Radiology and Oncology (ASTRO) proceedings were systematically searched from 2002 to 2010. Oral fluoropyrimidine trials were excluded owing to the unavailability of these agents in North America. RESULTS Overall, 22 randomized controlled trials (RCTs), 13 meta-analyses, and two secondary analyses were included. The systematic review informed the development of a clinical practice guideline with the following recommendations. Postoperative 5-fluorouracil-based chemoradiotherapy based on the Macdonald approach or perioperative ECF (epirubicin, cisplatin, fluorouracil) chemotherapy based on the Cunningham/MAGIC (Medical Research Council Adjuvant Gastric Infusional Chemotherapy) approach are both acceptable standards of care in North America. Choice of treatment should be made on a case-by-case basis. Adjuvant chemotherapy is a reasonable option for those patients for whom the Macdonald and MAGIC protocols are contraindicated. All patients with resectable gastric cancer should undergo a pretreatment multidisciplinary assessment to determine the best plan of care. CONCLUSIONS Overall survival in patients with resectable gastric cancer is significantly improved with the use of either postoperative chemoradiation (Macdonald approach) or perioperative ECF (MAGIC protocol).

Abstract
A 39-year old patient with gastric adenocarcinoma stage IV failed to respond to preoperative chemotherapies containing 5-FU and cisplatin as well as 5-FU and irinotecan. After third-line chemotherapy with two cycles of docetaxel and cisplatin we confirmed a clinical partial response. A complete histologically confirmed remission was detected after complete resection of the tumor. Following two postoperative cycles of docetaxel and cisplatin, the tumor is still in complete remission after more than eight years.

Abstract
Stomach cancer is one of the most common cancers worldwide, despite its declining overall incidence. Although there are differences in incidence, etiology and pathological factors, most studies do not separately analyze cardia and noncardia gastric cancer. Surgery is the only potentially curative treatment for advanced, resectable gastric cancer, but locoregional relapse rate is high with a consequently poor prognosis. To improve survival, several preoperative and postoperative treatment strategies have been investigated. Whereas perioperative chemotherapy and postoperative chemoradiation (CRT) are considered standard therapy in the Western world, in Asia postoperative monochemotherapy with S-1 is often used. Several other therapeutic options, although generally not accepted as standard treatment, are postoperative combination chemotherapy, hyperthermic intraperitoneal chemotherapy and preoperative radiotherapy and CRT. Postoperative combination chemotherapy does show a statistically significant but clinically equivocal survival advantage in several meta-analyses. Hyperthermic intraperitoneal chemotherapy is mainly performed in Asia and is associated with a higher postoperative complication rate. Based on the currently available data, the use of postoperative radiotherapy alone and the use of intraoperative radiotherapy should not be advised in the treatment of resectable gastric cancer. Western randomized trials on gastric cancer are often hampered by slow or incomplete accrual. Reduction of toxicity for preoperative and especially postoperative treatment is essential for the ongoing improvement of gastric cancer care.

Abstract
Gastric adenocarcinoma is one of the most common causes of death worldwide. Surgical resection remains the mainstay of therapy, offering the only chance for complete cure. Resection is based on the principles of obtaining adequate margins, with the extent of lymphadenectomy remaining controversial. Neoadjuvant and adjuvant therapies are used to reduce local recurrence and improve long-term survival. This article reviews the literature and provides a summary of surgical management options and neoadjuvant/adjuvant therapies for gastric adenocarcinoma.

Clin Oncol (R Coll Radiol) 2011; 23:696-705. [PMID: 21684129 DOI: 10.1016/j.clon.2011.05.005] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2011] [Revised: 03/22/2011] [Accepted: 05/18/2011] [Indexed: 02/07/2023]
Abstract
AIMS The optimal neoadjuvant therapy option for locally advanced oesophageal cancer remains elusive. Neoadjuvant chemoradiotherapy (CRT) is the preferred modality of choice in the USA. In contrast, neoadjuvant chemotherapy is commonly used in the UK. We provide a comprehensive overview of the available evidence for defining the ideal neoadjuvant treatment algorithm. MATERIALS AND METHODS The PubMed database combined with American Society of Clinical Oncology and American Society for Therapeutic Radiology and Oncology websites were searched online to identify randomised studies and published meta-analyses that have compared these modalities compared with surgery alone. In particular, we searched for randomised trials that may have directly compared outcomes after neoadjuvant CRT or chemotherapy. RESULTS We identified 17 published randomised studies of neoadjuvant CRT (n = 9) and chemotherapy (n = 8) compared with surgery alone and one prospective series that compared the above modalities against each other. Studies evaluating CRT have reported pathological complete response rates of 15-40% and no increase in postoperative mortality was observed, except in one study that used a hypofractionated radiation schedule. Two randomised studies showed significant survival benefit and the remaining (n = 7) were negative, but showed a trend towards improved survival. Furthermore, at least four meta-analyses have shown improved survival in favour of CRT extending up to an absolute benefit of 13% at 2 years. In comparison, five studies of neoadjuvant chemotherapy showed no survival difference and two of the remaining studies that showed significant benefit included gastric adenocarcinomas and used peri-operative chemotherapy. All the above studies have shown uniformly poor pathological complete response rates of less than 10 percent. Moreover, three meta-analyses were negative, but two showed up to 7% absolute survival benefit at 2 years in favour of chemotherapy. The trial comparing the above modalities showed a trend towards improved survival in favour of CRT, but closed early due to poor recruitment. CONCLUSION Data from the above studies are potentially conflicting and inconclusive for defining the optimal neoadjuvant treatment schedule. In our opinion, the above question can only be answered within the context of a randomised control trial. We have included a proposal for a trial design for direct comparison of these modalities.

Abstract
Although recent advances have been made, surgery still remains the mainstay of any curative treatment for gastric cancer patients, with radical gastrectomy representing the procedure of choice. However, patients with locally advanced disease show high rates of locoregional or distant recurrence even after potentially curative resections. According to global results presented in the setting of locally advanced resectable gastric carcinoma, perioperative chemotherapy may be considered a valuable option. On the other hand, clinical trials for advanced gastric cancer seem to suggest that a limit in efficacy has been reached for standard chemotherapy. Interesting data are expected from the development of targeted agents that, similarly to other cancer sites, showed appealing results in gastric cancer as well. Along with new effective therapeutic opportunities, better clinical and molecularly driven patient selection will represent the cornerstone of the global care for these patients.

Abstract
BACKGROUND Free peritoneal tumor cells (FPTCs) are an independent prognostic factor in patients undergoing curative resection for gastric carcinoma. Whether neoadjuvant chemotherapy (NAC) can eliminate FPTCs in the peritoneal lavage remains unclear. The aim of the study was to determine the effect of NAC on FPTCs. METHODS From 1994 to 2000, data from a total of 61 patients with resectable gastric cancer were analyzed. Peritoneal cytology was performed before NAC at laparoscopy and at tumor resection. A minimum of 6 weeks of NAC, consisting of cisplatin, folinic acid, and fluorouracil, was administered. FPTCs were detected immunohistochemically with Ber-EP4 antibody. RESULTS No FPTCs could be detected in 42 patients (69%), compared to 19 (31%) with FPTCs before NAC. During chemotherapy, 10 (24%) of 42 patients developed FPTCs, and 7 (37%) of 19 patients reverted from positive to negative. Patients who became FPTC negative (n = 7) showed an improved median survival (36.1 months) and a longer 2-year survival (71.4%) compared to FPTC-positive patients before and after NAC (n = 12), with a median survival of 9.2 months and a 2-year survival rate of 25%. In contrast, patients who reverted from FPTC negative to positive during NAC (n = 10) had a median survival of 18.5 months and a 2-year survival of only 20%. Multivariate analysis identified ypN category and FPTC change as independent prognostic factors. CONCLUSIONS NAC for patients with positive cytology could lead to FPTC negativity in a subset of patients and improve their prognosis. However, NAC might be a risky strategy for almost one-quarter of patients whose disease develops positive cytology.

Abstract
We have reviewed the pivotal presentations related to gastrointestinal malignancies from 2009 annual meeting of the American Society of Clinical Oncology with the theme of "personalizing cancer care". We have discussed the scientific findings and the impact on practice guidelines and ongoing clinical trials. Adding trastuzumab to chemotherapy improved the survival of patients with advanced gastric cancer overexpressing human epidermal growth factor receptor 2. Gemcitabine plus cisplatin has become a new standard for first-line treatment of advanced biliary cancer. Octreotide LAR significantly lengthened median time to tumor progression compared with placebo in patients with metastatic neuroendocrine tumors of the midgut. Addition of oxaliplatin to fluoropyrimidines for preoperative chemoradiotherapy in patients with stage II or III rectal cancer did not improve local tumor response but increased toxicities. Bevacizumab did not provide additional benefit to chemotherapy in adjuvant chemotherapy for stage II or III colon cancer. In patients with resected stage II colon cancer, recurrence score estimated by multigene RT-PCR assay has been shown to provide additional risk stratification. In stage IV colorectal cancer, data have supported the routine use of prophylactic skin treatment in patients receiving antibody against epidermal growth factor receptor, and the use of upfront chemotherapy as initial management in patients with synchronous metastasis without obstruction or bleeding from the primary site.

Abstract
Neoadjuvant therapy is now an integral part in the treatment of locally advanced cancer of the esophagus and stomach. The mechanisms of action comprise downsizing of the primary tumor, improvement of the T and N categories and the earliest possible eradication of micrometastases. Several controlled clinical studies could show that these principles can indeed augment the rate of curative (R0) resections and can reduce the likelihood of systemic recurrences. As a consequence overall survival is improved by neoadjuvant therapy. This article summarizes how the basic principles of neoadjuvant therapy translate into clinical practice and gives a review of current developmental perspectives in this field.
