Liquid biopsy: circulating tumor DNA monitors neoadjuvant chemotherapy response and prognosis in stage II/III gastric cancer. Mol Oncol 2023; 17:1930-1942. [PMID: 37356061 PMCID: PMC10483607 DOI: 10.1002/1878-0261.13481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 03/09/2023] [Accepted: 06/23/2023] [Indexed: 06/27/2023] Open
Abstract
A good response to neoadjuvant chemotherapy (NACT) is strongly associated with a higher curative resection rate and favorable outcomes for patients with gastric cancer (GC). We examined the utility of serial circulating tumor DNA (ctDNA) testing for monitoring NACT response and prognosis in stage II-III GC. Seventy-nine patients were enrolled to receive two cycles of NACT following gastrectomy with D2-lymphadenectomy. Plasma at baseline, post-NACT, and after surgery, and tissue at pretreatment and surgery were collected. We used a 425-gene panel to detect genomic alterations (GAs). Results show that the mean cell-free DNA concentration of patients with clinical stage III was significantly higher than patients with stage II (15.43 ng·mL-1 vs 14.40 ng·mL-1 ). After receiving NACT and surgery, the overall detection rate of ctDNA gradually reduced (59.5%, 50.8%, and 47.4% for baseline, post-NACT, and postsurgery). The maximum variant allele frequency (max-VAF) and the number of GAs decreased from 0.50% to 0.08% and from 2.9 to 1.7 after NACT. For patients with a partial response after NACT, the max-VAF and the number of GAs declined significantly, but they increased for patients with progressive disease. Patients with detectable ctDNA at baseline, after NACT, or after surgery have a worse overall survival (OS) than patients with undetectable ctDNA. The estimated 3-year OS was 73% for the post-NACT ctDNA-negative patients and 34% for ctDNA-positive. Patients with perpetual negative ctDNA before and after NACT have the best prognosis. In conclusion, ctDNA was proposed as a potential biomarker to predict prognosis and monitor the NACT response for stage II-III GC patients.

Abstract
Surgery still represents the mainstay of treatment of all stages of gastric cancer (GC). Surgical resections represent potentially curative options in the case of early GC with a low risk of node metastasis. Sentinel lymph node biopsy and indocyanine green fluorescence are novel techniques which may improve the employment of stomach-sparing procedures, ameliorating quality of life without compromising oncological radicality. Nonetheless, the diffusion of these techniques is limited in Western countries. Conversely, radical gastrectomy with extensive lymphadenectomy and multimodal treatment represents a valid option in the case of advanced GC. Differences between Eastern and Western recommendations still exist, and the optimal multimodal strategy is still a matter of investigation. Recent chemotherapy protocols have made surgery available for patients with oligometastatic disease. In this context, intraperitoneal administration of chemotherapy via HIPEC or PIPAC has emerged as an alternative weapon for patients with peritoneal carcinomatosis. In conclusion, the surgical management of GC is still evolving together with the multimodal strategy. It is mandatory for surgeons to be conscious of the current evolution of the surgical management of GC in the era of multidisciplinary and tailored medicine.

Abstract
OPINION STATEMENT Gastric cancer is an aggressive malignancy, requiring a multimodality approach to achieve optimal curative rates even when the disease is amenable to surgical resection. Neoadjuvant and adjuvant approaches differ across the globe-a preference for peri-operative chemotherapy exists in Europe, in contrast to the adoption of adjuvant chemotherapy in Asia and adjuvant chemoradiotherapy in North America. There are nuances and limitations associated with each therapeutic strategy and an understanding of these distinct approaches is integral to judicious clinical application of the available data. Although a multimodal approach provides a clear survival benefit above a surgical-only approach, data report low completion rates of adjuvant therapy components and strongly suggest a need to refine patient selection particularly for ongoing treatment in the post-operative period. This may be achieved using a risk-stratified strategy. Hence, there is a need to transition from a generalised approach to a multimodality treatment towards one guided by individual patient clinical features and biomarker profiles in order to improve tolerability and patient outcomes irrespective of geographical variation in clinical practice. While the evidences supporting molecular features such as microsatellite instability and predictive gene signatures are provocative, prospective validation is required before these can be confidently used to direct clinical decision-making.

Abstract
Gastric and gastroesophageal junction (GEJ) cancers represent an aggressive group of malignancies with poor prognosis even when diagnosed in relatively early stage, with an increasing incidence both in Asia and in Western countries. These cancers are characterized by heterogeneity as a result of different pathogenetic mechanisms as shown in recent molecular analyses. Accordingly, the understanding of phenotypic and genotypic correlations/classifications has been improved. Current therapeutic strategies have also advanced and moved beyond surgical extirpation alone, with the incorporation of other treatment modalities, such as radiation and chemotherapy (including biologics). Chemoradiotherapy has been used as postoperative treatment after suboptimal gastrectomy to ensure local disease control but also improvement in survival. Preoperative chemoradiotherapy/chemotherapy has been employed to increase the chance of a successful R0 resection and pathologic complete response rate, which is associated with improved long-term outcomes. Several studies have defined various chemotherapy regimens to accompany radiation (before and after surgery). Recently, addition of immunotherapy after trimodality of gastroesophageal cancer has produced an advantage in disease-free interval. Targeted agents used in the metastatic setting are being investigated in the early setting with mixed results. The aim of this review is to summarize the existing data on trimodality approaches for gastric and GEJ cancers, highlight the remaining questions and present the current research effort addressing them.

Abstract
BACKGROUND Perioperative or neoadjuvant therapy is the mainstay of treatment for locally advanced gastric cancer in Europe; however, data regarding possible modifications in the surgical strategy depending on the response to preoperative treatment are lacking. METHODS This review was carried out based on a search of the relevant contemporary literature regarding neoadjuvant or perioperative treatment for gastric adenocarcinoma and the implications of tumor response for the subsequent surgical treatment. RESULTS The most recent randomized trials showed a survival benefit after perioperative or neoadjuvant treatment for gastric cancer. Due to the variable response to the preoperatively administered part of the therapy, including complete response, it appears reasonable to develop an individualized surgical approach; however, scientific results supporting this approach are limited due to the variable quality of the surgical resection provided in these studies and the limited rate of complete response to preoperative treatment. Moreover, the reliability of clinical restaging after preoperative treatment is also limited. On the other hand, there is currently evidence that supports a re-evaluation of the necessary resection margins for partial gastrectomy in advanced gastric cancer with the help of intraoperative frozen sections and new reconstruction methods. CONCLUSION The current evidence does not support the implementation of a complete organ-sparing strategy with active follow-up surveillance for gastric cancer.; however, stomach-preserving partial gastrectomy techniques could be applied for advanced disease more often in the future.

Abstract
OBJECTIVE The aim of this study was to compare the clinical efficacy of neoadjuvant chemoradiotherapy (NACRT) combined with postoperative adjuvant XELOX (Oxaliplatin +Capecitabine) chemotherapy and postoperative adjuvant chemotherapy (ACT) with XELOX for local advanced gastric cancer (LAGC). METHODS In this prospectively randomized trial, we investigated the effect of NACRT combined with postoperative ACT for LAGC. 60 patients were randomly divided into NACRT group and ACT group, with 30 patients in each group. Patients in NACRT group were given three-dimensional conformal radiotherapy (45 Gy/1.8 Gy/f) accompanied by synchronous XELOX of two cycles, followed by surgery, and then postoperative adjuvant XELOX chemotherapy of four cycles was performed. Patients in ACT group received surgery in advance, and then XELOX chemotherapy of six cycles was given. RESULTS The objective response rate of NACRT was 76.7%. The overall incidence of postoperative complications in NACRT group was not significantly different from that in ACT group (23.1% vs 30.0%, p = 0.560). The 1 year, 2 years, and 3 years progression-free survival (PFS)and overall survival (OS) in NACRT and ACT groups were 80.0% vs 56.7%, 73.3% vs 46.7%, 60.0% vs 33.3%, and 86.7% vs 80.0%, 76.7% vs 66.7%, 63.3% vs 50.0%, respectively. Patients in NACRT group showed a significantly higher R0 resection rate (84.6% vs 56.7%, p = 0.029),lower loco-regional recurrence rate (36.7% vs 11.5%, p = 0.039), longer PFS (p = 0.019) and freedom from locoregional progression(FFLP) (p = 0.004) than patients in ACT group, while there was no difference in OS (p = 0.215) and in toxicity incidence (p > 0.05). CONCLUSIONS NACRT combined with postoperative adjuvant XELOX chemotherapy can improve R0 resection rate, reduce loco-regional recurrence, prolong PFS and FFLP without increasing the incidence of postoperative complications in patients with LAGC. ADVANCES IN KNOWLEDGE Compared with postoperative adjuvant chemotherapy, locally advanced gastric cancer patients may benefit from neoadjuvant chemoradiotherapy, and toxicity associated with chemoradiotherapy was tolerant and manageable.

Abstract
BACKGROUND This prospective phase I/II trial assessed feasibility and efficacy of dose-escalated definitive chemoradiation after induction chemotherapy in locally advanced esophageal cancer. Primary study endpoint was loco-regional progression-free survival at 1 year. METHODS Eligible patients received 2 cycles of induction chemotherapy with irinotecan, folinic acid and 5-fluorouracil weekly and cisplatin every 2 weeks (weeks 1-6, 8-13) followed by concurrent chemoradiation with cisplatin and irinotecan (weeks 14, 15, 17, 18, 20). Radiotherapy dose escalation was performed in three steps (60 Gy, 66 Gy, 72 Gy) using conventional fractionation, planning target volumes were delineated with the aid of 18F-FDG-PET/CT scans. During follow-up, endoscopic examinations were performed at regular intervals. RESULTS Between 09/2006 and 02/2010, 17 patients were enrolled (male/female:13/4, median age: 59 [range 48-66] years, stage uT3N0/T3N1/T4N1: 4/12/1). One patient progressed during induction chemotherapy and underwent surgery. Of 16 patients treated with definitive chemoradiotherapy, 9 (56%) achieved complete response after completion of chemoradiation. One-, 2-, 3- and 5-year overall survival rates (OS) were 77% [95%CI: 59-100], 53% [34-83], 41% [23-73], and 29% [14-61], respectively. Loco-regional progression-free survival at 1, 3, and 5 years was 59% [40-88], 35% [19-67], and 29% [14-61], corresponding cumulative incidences of loco-regional progressions were 18% [4-39%], 35% [14-58%], and 41% [17-64%]. No treatment related deaths occurred. Grade 3 toxicities during induction therapy were: neutropenia (41%), diarrhoea (41%), during combined treatment: neutropenia (62%) and thrombocytopenia (25%). CONCLUSIONS Dose-escalated radiotherapy and concurrent cisplatin/irinotecan after cisplatin/irinotecan/5FU induction chemotherapy was tolerable. The hypothesized phase II one-year loco-regional progression free survival rate of 74% was not achieved. Long-term survival compares well with other studies on definitive radiotherapy using irinotecan and cisplatin but is not better than recent trials using conventionally fractionated radiotherapy ad 50 Gy with concurrent paclitaxel or 5FU and platinum compound. Trial registration The present trial was registered as a phase I/II trial at the EudraCT database: Nr. 2005-006097-10 ( https://www.clinicaltrialsregister.eu/ctr-search/trial/2005-006097-10/DE ) and authorized to proceed on 2006-09-25.

Abstract
BACKGROUND Level 1 evidence for multimodal treatment of resectable gastric adenocarcinoma from the Intergroup 0116 (2001) and MAGIC (2006) trials demonstrated survival benefit of adjuvant chemoradiation (CRT) and perioperative chemotherapy, respectively. We evaluated the adoption of evidence-based treatment in the post-MAGIC era and its impact on survival. METHODS A total of 7058 patients with resectable gastric adenocarcinoma undergoing definitive surgical resection between 2004 and 2015 were analyzed using the National Cancer Database. RESULTS Over the study period, the proportion of patients receiving adjuvant CRT decreased from 19.1% to 9.1%, while perioperative chemotherapy increased from 1.9% to 28.6%. Utilization of perioperative chemotherapy surpassed adjuvant CRT in 2011. Evidence-based treatment (either perioperative chemotherapy or adjuvant CRT) had better overall survival (OS) than other treatments for clinical stage II-III patients (p < 0.05). On multivariate analysis of the whole study period, evidence-based treatments were associated with better OS (HR 0.67 [0.60-0.74], p < 0.05). Only 360/1262 (28.5%) patients in the perioperative chemotherapy group completed postoperative therapy, which was associated with improved OS (p < 0.05). For clinical stage III patients (n = 2402), only 806 (33.6%) received evidence-based treatment, while 487 (22.2%) underwent surgery alone. On multivariate analysis of these patients between 2010 and 2015, both perioperative chemotherapy (HR 0.49 [0.35-0.68]) and adjuvant CRT (HR 0.31 [0.21-0.44]) were associated with better OS than surgery alone (p < 0.05). CONCLUSIONS Since the INT-0116 and MAGIC trials, utilization of evidence-based treatments for resectable gastric adenocarcinoma has increased, with perioperative chemotherapy surpassing adjuvant CRT as the preferred practice. However, overall utilization of these regimens remains quite low nationally despite association with improved OS.

Abstract
Gastric cancer is one of the most common digestive system tumors in China, and locally advanced gastric cancer (LAGC) accounts for a high proportion of newly diagnosed cases. Although surgery is the main treatment for gastric cancer, surgical excision alone cannot achieve satisfactory outcomes in LAGC patients. Neoadjuvant therapy (NAT) has gradually become the standard treatment for patients with LAGC, and this treatment can not only achieve tumor downstaging and improve surgical rate and the R0 resection rate, but it also significantly improves the long-term prognosis of patients. Peri/preoperative neoadjuvant chemotherapy and preoperative chemoradiotherapy are both recommended according to a large number of studies, and the regimens have also been evolved in the past decades. Since the NCCN guidelines for gastric cancer are one of the most authoritative evidence-based guidelines worldwide, here, we demonstrate the development course and major breakthroughs of NAT for gastric cancer based on the vicissitudes of the NCCN guidelines from 2007 to 2019, and also discuss the future of NAT.

Abstract
Background: Controversy continues regarding the optimal strategy of multimodality therapies for resectable gastric cancer. The aim of this network meta-analysis was to determine the efficacy of surgery combined with neoadjuvant or adjuvant chemotherapy (CT), radiotherapy (RT), and chemoradiotherapy (CRT) by integrating the direct and indirect method. Methods: A systematic search for randomized controlled trials (RCTs) was performed through Medline, Embase, CENTRAL, and PMC databases. Overall survival (OS) was the primary outcome of interest. A Bayesian network meta-analysis was conducted and treatments were ranked based on their effectiveness for improving survival. Results: Fifty-six RCTs involving 12,435 patients were included. Overall analysis showed that neoadjuvant CRT resulted in a statistically significantly better OS compared with adjuvant CT, adjuvant RT, adjuvant CRT, neoadjuvant CT, neoadjuvant RT, and surgery alone. Moreover, subgroup analysis of D2 lymphadenectomy revealed that neoadjuvant CRT was not significant superior to neoadjuvant CT (HR = 0.67, 95% CrI 0.41-1.08), adjuvant CRT (HR = 0.67, 95% CrI 0.37-1.21), and adjuvant CT (HR = 0.60, 95% CrI 0.35-1.04). With a tendency to survival benefit, neoadjuvant CRT had an 89% probability of being the best selection. Conclusions: Our study showed no significant survival advantage for neoadjuvant CRT, though the highest probability of being the best treatment was observed. Further clinical trials are essential to determine the value of neoadjuvant CRT, especially in D2 lymphadenectomy subgroup.

Abstract
INTRODUCTION Patients with cancer are subject to the cardiotoxic effects of cancer therapy and as more patients survive cancer due to improved treatment they are exposed to various forms of cardiovascular (CV) disease as they age, and vice-versa. Such an interplay of age with both malignancy and CV disease may contribute to increased morbidity and mortality. AREAS COVERED This two-part review considers the effects of cancer drug treatment on the CV system. In Part I, the various types of CV and cardiometabolic toxicity of anti-cancer drugs and the possible mechanisms involved are discussed. Also, among the specific oncologic agents, the CV effects of the classical agents and of the large molecule immunological agents (monoclonal antibodies, including immune checkpoint inhibitors) are detailed. EXPERT OPINION Oncologic agents produce a variety of CV adverse effects, including cardiomyopathy and heart failure, peri-myocarditis, coronary artery disease, peripheral vascular disease, hypertension (HTN), cardiac arrhythmias, valvular heart disease, and pulmonary HTN. Both the oncologist and the cardiologist need to be aware of such adverse effects and of the specific agents that produce them. They need to join forces to prevent, anticipate, recognize, and manage such complications.

Abstract
BACKGROUND AND OBJECTIVES Staging laparoscopy is recommended before preoperative therapy in patients with locoregional gastric cancer, but yield of repeated diagnostic laparoscopy at the time of resection is unknown. METHODS Retrospective review of a prospective database of patients with gastric adenocarcinoma (1994-2016) who had negative staging laparoscopy followed by preoperative therapy and subsequent attempted resection. Primary outcome was positive exploration (peritoneal or unresectable disease) at the time of resection. Multivariable logistic regression identified factors associated with positive exploration. RESULTS Of the 451 patients with attempted resection, 54 (12.0%) had positive explorations, including 48 with peritoneal disease. Patients with positive explorations were more likely to be female and have poorly differentiated tumors, linitis features, and signet-ring morphology. There was no significant difference by exploration results in age, race, clinical stage, or delayed definitive surgery. Positive explorations were independently associated with poor differentiation (OR 4.6, 95%CI 1.4-15.3; P = 0.01) and linitis (OR 4.2, 95%CI 1.9-9.2; P < 0.001). Positive explorations were seen in 14.0% of patients with poor differentiation, 36.6% of patients with linitis, and 5.8% of patients with neither linitis nor poor differentiation. CONCLUSION Despite negative pretreatment laparoscopy, post-treatment repeat laparoscopy may prevent non-therapeutic laparotomies. At a minimum, we recommend selective repeat laparoscopy for patients with linitis features.

Abstract
The advent of immune checkpoint inhibitors (PD-1, PD-L1 and CTLA-4) has resulted in unprecedented long-term remissions of unresectable cancers. The efficacy of checkpoint inhibitors was recently demonstrated in gastrointestinal malignancies with mismatch repair deficiencies (dMMR). Pembrolizumab became the first tissue-agnostic US FDA-approved drug based on the presence of the predictive biomarker dMMR. In addition, the FDA in 2017 approved pembrolizumab for PD-L1-positive advanced gastric cancer in third-line and second-line hepatocellular therapy. Novel treatment strategies such as using anti-carcinoembryonic antigen (CEA) bispecific T cells have led to remarkable responses in microsatellite instability-low colorectal cancer. Other major breakthroughs in treating upper gastrointestinal malignancies in 2017 are discussed.

Abstract
Gastroesophageal adenocarcinomas (GEACs) remain a global health problem. These are most often diagnosed at advanced stage and the estimated 5-year relative survival rate is about 5%. Although cure is not possible for patients with advanced GEAC, systemic therapy (chemotherapy or biochemotherapy) can palliate symptoms, improve survival and provide a better quality of life. One of the most promising options for some patients with advanced stage GEAC is immunotherapy, which can result in durable responses. Numerous phase III trials evaluating targeted therapies in different lines are ongoing and it is hoped that better biomarkers will emerge to identify patients who can benefit from targeted agents and immunotherapy in the future. Surgery remains as the corner stone for localized GEAC and adjunctive therapies can increase the survival rates by about 10%. The high toxicity and low completion rates of adjuvant therapy led to the strategies of preoperative treatment. With the results of ongoing pre-operative therapy trials we will be able to determine the optimal adjunctive approach for resectable GEAC.

Histopathologic Features are more Important Prognostic Factors than Primary Tumour Location in Gastro-oesophageal Adenocarcinoma Treated with Preoperative Chemoradiation and Surgery. Pathol Oncol Res 2017; 24:373-383.

Abstract
The aim of present study was to evaluate the impact of primary tumour location and other factors on the outcome of preoperative chemoradiation followed by surgery in adenocarcinomas of distal oesophagus, gastro-oesophageal junction and stomach. We retrospectively reviewed the institutional patient database. The therapeutic response was re-evaluated as a percentage of residual tumor cells in surgical resection specimens. Overall survival (OS) and disease-free survival (DFS) were assessed. The effect primary tumour location, clinical and pathological TNM stage, and histopathological factors (histological type, grade, angioinvasion, perineural invasion, tumour response) on treatment outcome were evaluated. A total of 108 patients underwent preoperative chemoradiation for adenocarcinoma of distal oesophagus, gastro-oesophageal junction or stomach. The median prescribed dose of radiation was 45 Gy. The concurrent chemotherapy consisted of 5-fluorouracil +/- cisplatin +/- taxanes. R0 resection was achieved in 80 patients (74%). The complete response was observed in 19%. The median follow-up was 50.8 months. Three-year and 5-year OS and DFS were 36.2% and 25.3%; and 28.1% and 23.7%, respectively. Pretreatment T-stage, pathological N-stage, radicality of resection, histological subtype, grade, angioinvasion and perineural invasion, were identified as statistical significant OS predictors in univariate analysis; pathological N-stage, radicality of resection and angioinvasion, in multivariate analysis. The primary tumor location did not influence the prognosis. The pathologic response to chemoradiation had borderline significance. In conclusion, no prognostic impact of primary tumour location, in contrast to other investigated factors, was evident in the present study. The most important predictors of prognosis were angioinvasion status and pN-stage.

Abstract
IMPORTANCE While neoadjuvant chemoradiation for esophageal cancer improves oncologic outcomes for a broad group of patients with locally advanced and/or node-positive tumors, it is less clear which specific subset of patients derives most benefit in terms of overall survival (OS). OBJECTIVE To determine whether neoadjuvant chemoradiation based on esophageal adenocarcinoma histology has similar oncologic outcomes for patients treated with surgery alone when stratified by clinical nodal status. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis using the American College of Surgeons National Cancer Database from 1998 to 2006. Patients with esophageal adenocarcinoma histology and clinical stage T1bN1-N3 or T2-T4aN-/+M0 were divided into 2 treatment groups: (1) neoadjuvant chemoradiation followed by surgery and (2) surgery alone. Subset analysis within each treatment group was performed for clinically node-negative patients (cN-) vs node-positive patients (cN+) in conjunction with pathological nodal status. A propensity score-adjusted analysis, which included patient demographics, comorbidity status, and clinical T stage, was also performed. MAIN OUTCOME AND MEASURES The primary outcome was 3-year OS. Secondary outcomes included margin status, postoperative length of stay, unplanned readmission rate, and 30-day mortality. RESULTS A total of 1309 patients were identified, of whom 539 received neoadjuvant chemoradiation followed by surgery and 770 received surgery alone. Of the 1309 patients, 41.2% (n = 539) received neoadjuvant chemoradiation and 47.2% (n = 618) were cN+. Median follow-up for the entire cohort was 73.3 months (interquartile range, 64.1-93.5 months). The 3-year OS was better for neoadjuvant chemoradiation followed by surgery compared with surgery alone (49% vs 38%, respectively; P < .001). Stratifying based on clinical nodal status, the propensity score-adjusted OS was significantly better for cN+ patients who received neoadjuvant chemoradiation (hazard ratio, 0.52; 95% CI, 0.42-0.66; P < .001). In contrast, there was no difference in OS for cN- patients based on treatment (hazard ratio, 0.84; 95% CI, 0.65-1.10; P = .22). CONCLUSIONS AND RELEVANCE Patients with cN+ esophageal adenocarcinoma benefit significantly from neoadjuvant chemoradiation. However, patients with cN- tumors treated with neoadjuvant chemoradiation plus surgery do not derive a significant OS benefit compared with surgery alone. This finding may have significant implications on the use of neoadjuvant chemoradiation in patients with cN- disease.

Abstract
Perioperative chemoradiotherapy is considered to be one of the standards of care for early-stage gastric cancer, especially when it involves the esophagogastric junction or greater curvature. To date, there are no reported cases of gastrointestinal perforation in the literature, including many major clinical trials of adjuvant or neoadjuvant chemoradiotherapy for gastric cancer. It is important to recognize and manage this rare, but fatal complication in a timely manner. We report one case of gastrointestinal perforation in a gastric cancer patient undergoing neoadjuvant chemoradiotherapy with 5-fluorouracil and oxaliplatin. A 75-year-old man was diagnosed with stage IV gastric cancer (T4N1M0). We started neoadjuvant chemoradiotherapy with 5-fluorouracil and oxaliplatin. After he finished the first cycle, the patient presented to emergency room with severe abdominal pain of sudden onset. Computed tomography showed moderate pneumoperitoneum and perihepatic fluid. The patient expired 6 hours after he presented to emergency room.

Abstract
The purpose of this study was to determine if international guidelines differ in their recommendations concerning additive therapy for advanced, but potentially curable, gastric cancer. A systematic search of the English and German literature was conducted in the databases Medline, Cochrane Database, Embase, and PubMed. The search terms used were 'guidelines gastric cancer,' 'guidelines stomach cancer,' and 'Leitlinien Magenkarzinom.' Six different guidelines published after January 1, 2010, in which the tumors were classified according to the seventh edition of the TNM system (2010), were identified. Although the examined guidelines were based on the same study results, their recommendations concerning accompanying therapy for gastric cancer differ considerably. While perioperative chemotherapy is recommended in Germany, Great Britain, and large parts of Europe, postoperative adjuvant radiochemotherapy or perioperative chemotherapy is recommended in the USA and Canada. In Japan, postoperative adjuvant chemotherapy is recommended.The results of identical studies were interpreted differently in different countries. Since considerable effort is required for each country to separately test relevant studies for their validity and suitability, an international cooperation could simplify the creation of a common basis for guidelines and contribute to improved comparability of international guidelines.

Abstract
Background. To purpose of the study was to analyze the results of preoperative radiochemotherapy in patients with unresectable gastric or locoregionally advanced gastroesophageal junction (GEJ) cancer treated at a single institution. Patients and methods. Between 1/2004 and 6/2012, 90 patients with locoregionally advanced GEJ or unresectable gastric cancer were treated with preoperative radiochemotherapy at the Institute of Oncology Ljubljana. Planned treatment schedule consisted of induction chemotherapy with 5-fluorouracil and cisplatin, followed by concomitant radiochemotherapy four weeks later. Three-dimensional conformal external beam radiotherapy was delivered by dual energy (6 and 15 MV) linear accelerator in 25 daily fractions of 1.8 Gy in 5 weeks with two additional cycles of chemotherapy repeated every 28 days. Surgery was performed 4–6 weeks after completing radiochemotherapy. Following the surgery, multidisciplinary advisory team reassessed patients for the need of adjuvant chemotherapy. The primary endpoints were histopathological R0 resection rate and pathological response rate. The secondary endpoints were toxicity of preoperative radiochemotherapy and survival. Results. Treatment with preoperative radiochemotherapy was completed according to the protocol in 84 of 90 patients (93.3%). Twenty patients (22.2%) did not undergo the surgery because of the disease progression, serious comorbidity, poor performance status or still unresectable tumour. In 13 patients (14.4%) only exploration was performed because the tumour was assessed as unresectable or diffuse peritoneal carcinomatosis was established. Fifty-seven patients (63.4%) underwent surgery with the aim of complete removal of the tumour. Radical resection was achieved in 50 (55.6%) patients and the remaining seven (7.8%) patients underwent non-radical surgery (R1 in five and R2 in two patients). In this group of patients (n = 57), pathological complete response of tumour was achieved in five patients (5.6% of all treated patients or 8.8% of all operated patients). Down-staging was recorded in 49 patients (86%), in one patient (1.8%) the stage after radiochemotherapy was unchanged while in seven patients (12.3%) the pathological stage was higher than clinical, mainly due to higher pN stage. No death was recorded during preoperative radiochemotherapy. Most grade 3 and 4 toxicities were due to vomiting, nausea and bone marrow suppression (granulocytopenia). Twenty-six (45.6%) patients died due to GEJ or gastric carcinoma, one died because of septic shock following the surgery and a reason for two deaths was unknown. Twenty-eight patients (49.1%) were disease free at the time of analysis, while 29 patients (50.9%) developed the recurrence, mostly as distant metastases. At two years, locoregional control, disease-free survival, disease-specific survival and overall survival were 82.9%, 43.9%, 56.9% and 53.9%, respectively. Conclusions. Preoperative radiochemotherapy was feasible in our group of patients and had acceptable toxicity. Majority of patients achieved down-staging, allowing greater proportion of radical resections (R0), which are essential for patients’ cure.

Abstract
BACKGROUND To date, few studies of preoperative chemotherapy or chemoradiotherapy (crt) in gastroesophageal junction (gej) cancer have been statistically powered; indeed, gej tumours have thus far been grouped with esophageal or gastric cancer in phase iii trials, thereby generating conflicting results. METHODS We studied 41 patients affected by locally advanced Siewert type i and ii gej adenocarcinoma who were treated with a neoadjuvant crt regimen [folfox4 (leucovorin-5-fluorouracil-oxaliplatin) for 4 cycles, and concurrent computed tomography-based three-dimensional conformal radiotherapy delivered using 5 daily fractions of 1.8 Gy per week for a total dose of 45 Gy], followed by surgery. Completeness of tumour resection (performed approximately 6 weeks after completion of crt), clinical and pathologic response rates, and safety and outcome of the treatment were the main endpoints of the study. RESULTS All 41 patients completed preoperative treatment. Combined therapy was well tolerated, with no treatment-related deaths. Dose reduction was necessary in 8 patients (19.5%). After crt, 78% of the patients showed a partial clinical response, 17% were stable, and 5% experienced disease progression. Pathology examination of surgical specimens demonstrated a 10% complete response rate. The median and mean survival times were 26 and 36 months respectively (95% confidence interval: 14 to 37 months and 30 to 41 months respectively). On multivariate analysis, TNM staging and clinical response were demonstrated to be the only independent variables related to long-term survival. CONCLUSIONS In our experience, preoperative chemoradiotherapy with folfox4 is feasible in locally advanced gej adenocarcinoma, but shows mild efficacy, as suggested by the low rate of pathologic complete response.

Performance of a nomogram predicting disease-specific survival after an R0 resection for gastric cancer in patients receiving postoperative chemoradiation therapy.

Abstract
PURPOSE The internationally validated Memorial Sloan-Kettering Cancer Center (MSKCC) gastric carcinoma nomogram was based on patients who underwent curative (R0) gastrectomy, without any other therapy. The purpose of the current study was to assess the performance of this gastric cancer nomogram in patients who received chemoradiation therapy after an R0 resection for gastric cancer. METHODS AND MATERIALS In a combined dataset of 76 patients from the Netherlands Cancer Institute (NKI), and 63 patients from MSKCC, who received postoperative chemoradiation therapy (CRT) after an R0 gastrectomy, the nomogram was validated by means of the concordance index (CI) and a calibration plot. RESULTS The concordance index for the nomogram was 0.64, which was lower than the CI of the nomogram for patients who received no adjuvant therapy (0.80). In the calibration plot, observed survival was approximately 20% higher than the nomogram-predicted survival for patients receiving postoperative CRT. CONCLUSIONS The MSKCC gastric carcinoma nomogram significantly underpredicted survival for patients in the current study, suggesting an impact of postoperative CRT on survival in patients who underwent an R0 resection for gastric cancer, which has been demonstrated by randomized controlled trials. This analysis stresses the need for updating nomograms with the incorporation of multimodal strategies.

Abstract
Gastric cancer is among the leading causes of cancer death worldwide. Surgery is the only curative modality, but mortality remains high because a significant number of patients have recurrence after complete surgical resection. Chemotherapy, radiation, and chemoradiotherapy have all been studied in an attempt to reduce the risk for relapse and improve survival. There is no globally accepted standard of care for resectable gastric cancer, and treatment strategies vary across the world. Postoperative chemoradiation with 5-fluorouracil/leucovorin is most commonly practiced in the United States; however, recent clinical trials from Asia have shown benefit of adjuvant chemotherapy alone and have questioned the role of radiation. In this review, we examine the current literature on adjuvant treatment of gastric cancer and discuss the roles of radiation and chemotherapy, particularly in light of these new data and their applicability to the Western population. We highlight some of the ongoing and planned clinical trials in resectable gastric cancer and identify future directions as well as areas where further research is needed.

Abstract
Esophageal cancer is one of the common malignant tumors. Multimodality treatment (including surgery, chemotherapy and radiotherapy) of esophageal cancer has become a consensus. Although there is currently no standard treatment, neoadjuvant chemoradiotherapy followed by surgery and postoperative adjuvant radiotherapy or chemotherapy based on risk factors, such as positive surgical margin and lymph node metastasis, and definitive chemoradiotherapy when inoperable, has been recommended by the NCCN Guidelines. In recent years, clinical trials show that targeted drugs can further improve the prognosis of esophageal cancer. How to choose chemotherapy drugs and develop reasonable treatment modality has become a hotspot of clinical research. This article aims to review recent progress in medication treatment of esophageal cancer.

Abstract
INTRODUCTION The specific aims of the study were to evaluate the 2-year overall survival (OS) and progression-free survival (PFS), toxicity profile, and best objective response rate in patients with locally advanced, clinically unresectable esophageal cancer receiving cetuximab, cisplatin, irinotecan, and thoracic radiotherapy (TRT) within a multi-institutional cooperative-group setting. METHODS Eligible patients (cT4 M0 or medically unresectable, biopsy proven, and noncervical esophageal cancer) were to receive four 21-day cycles of cetuximab 400 mg/m (day 1, cycle 1), cetuximab 250 mg/m (day 8, 15, cycle 1; then days 1, 8, and 15 for subsequent cycles), cisplatin 30 mg/m (days 1 and 8, all cycles), and irinotecan 65 mg/m (days 1 and 8, all cycles). TRT was administered at 1.8 Gy in 28 daily fractions to a total dose of 50.4 Gy, to begin with on day 1 of cycle 3. The primary endpoint was 2-year OS, with an accrual goal of 75 patients with adenocarcinoma. RESULTS The study was closed because of slow accrual, with 21 eligible patients (11 squamous, 10 adenocarcinoma) enrolled from May 2005 to September 2007. Two-year OS and PFS (95% confidence interval [CI]) were 33.3% (14.6-57.0%) and 23.8% (8.2-47.2%), respectively. Kaplan-Meier estimates of median (95% CI) OS and PFS were 11.2 (6.4-43.6) and 6.4 (3.7-12.0) months, respectively. The overall response rate (95% CI) among 17 evaluable patients was 17.6% (3.8-43.4%), including 6% confirmed complete responders and 12% unconfirmed partial responders. Two deaths resulted from protocol treatment (sudden death and gastrointestinal necrosis). Ten (47.6%) and 6 (28.6%) patients had grade-3 or -4 toxicity, respectively: 52.4% were hematologic, 23.8% had fatigue, 19.0% had nausea, 19.0% had dehydration, and 19.0% had anorexia. CONCLUSIONS Concomitant cetuximab, cisplatin, irinotecan, and TRT were poorly tolerated in the first North American cooperative group trial testing this regimen for locally advanced esophageal cancer as treatment-related mortality approached 10%. Single-institution phase-II cetuximab-based combined modality trials have yielded encouraging results in preliminary analyses. The SWOG GI Committee endorses enrollment to open clinical trials to clarify the therapeutic ratio of cetuximab-based combined modality approaches for esophageal cancer.

Abstract
INTRODUCTION Based on favorable preliminary clinical data and the need to identify effective, well-tolerated neoadjuvant regimens for patients with locally advanced esophageal cancer, this clinical trial was undertaken. METHODS This phase II study tested 500 mg/m neoadjuvant pemetrexed intravenously and carboplatin with an area under the curve of 6 intravenously on days 1 and 22 in conjunction with concomitant radiation of 5040 centigray, which was given in 28 daily fractions of 180 centigray. The primary endpoint was the rate of pathologic complete response. RESULTS This trial closed early because, during an interim analysis, the primary endpoint fell short. However, 26 eligible patients were accrued. Twenty (74%) were men. Performance scores of 0, 1, and 2 were seen in 16 (59%), 9 (33%), and 2 (7%), respectively. Among eligible patients, 6 of 26 (23%; 95% confidence interval 9-44%) demonstrated a pathologic complete response. Twenty-two underwent a complete cancer resection. The median survival was 17.8 months (95% confidence interval: 12.2-30.7 months). In the neoadjuvant setting, 22 patients had at least one grade 3 or worse adverse event, and 8 patients had at least one grade 4 event. Postoperatively (within 30 days of surgery), there were three deaths, one grade 4 event (thrombosis), and three grade 3 events. CONCLUSIONS The neoadjuvant regimen tested within this phase II trial demonstrated antineoplastic activity but fell short of yielding a complete pathologic response rate that merits further testing.

Abstract
BACKGROUND Several trials have been conducted to determine the feasibility of preoperative radiotherapy (RT) for gastric cancer. However, the absolute benefit from radiotherapy remains to be defined. In this study, the authors examined the use of preoperative RT (Pre-RT) and postoperative RT (PORT) in patients with gastric cancer from the Surveillance, Epidemiology, and End Results (SEER) database. METHODS The overall survival of patients who had nonmetastatic, resected gastric cancer between 2000 and 2006 was analyzed from the SEER database. Kaplan-Meier survival curves comparing Pre-RT, PORT, and no RT (No-RT) were analyzed using the log-rank test. A multivariate analysis (MVA) was conducted using Cox proportional hazards regression. RESULTS The authors identified 10,251 patients. There was no survival benefit for patients who received Pre-RT or PORT compared with No-RT patients for the entire cohort. Conversely, among lymph node-positive patients, there was a significant survival benefit from both Pre-RT and PORT compared with No-RT (log-rank test: PORT, P < .0001; Pre-RT, P = .0261). The median survival and 5-year overall survival among lymph node-positive patients were 22 months and 24%, respectively, for Pre-RT;29 months and 34%, respectively, for PORT; and 19 months and 20%, respectively, for No-RT. MVA demonstrated that Pre-RT, PORT, and removing ≥ 15 lymph nodes were independent predictors of improved survival, whereas tumor classification, lymph node status, tumor size, and tumor location were independent predictors of death. CONCLUSIONS The current results supported the use of Pre-RT in select patients with gastric cancer. However, additional trials will be needed to confirm these findings.

Abstract
PURPOSE OF REVIEW The treatment of gastric cancer has been rapidly evolving with the emergence of new cytotoxic drugs and targeted biologic agents. The purpose of this review is to provide an update in the treatment of localized and metastatic gastric cancer. RECENT FINDINGS Although the overall incidence of gastric cancer has been declining in the United States, the disease continues to be a devastating problem worldwide. Complete surgical resection offers the chance of cure for localized gastric cancer. However, local and distant recurrences are common. Adjuvant chemoradiation with 5-fluorouracil/leucovorin significantly improves disease-free survival and overall survival as demonstrated by the US Intergroup INT-116 study. Most recently, the UK Medical Research Council Adjuvant Gastric trial showed survival benefit with perioperative chemotherapy. Preoperative chemotherapy and chemoradiation have also been explored in several small randomized studies with encouraging results. However, this approach needs to be further confirmed in a large randomized phase III study. Finally, novel molecular targeting agents have been incorporated into the multimodality treatment and shown promising response rate and progression-free survival. SUMMARY Gastric cancer remains one of the most clinically challenging cancers among all gastrointestinal malignancies. Mutimodality approach clearly offers survival benefit over surgery alone. In the United States, preoperative chemoradiation or postoperative adjuvant chemoradiation is widely practiced in major centers.

Abstract
PURPOSE The prognosis of patients with unresectable M0 gastric cancer remains very poor. We performed a phase II trial to explore the efficacy and toxicity of induction irinotecan-cisplatin (IC) followed by concurrent irinotecan-cisplatin and radiotherapy (IC/RT) in this setting. METHODS AND MATERIALS Patients with unresectable M0 gastric (GC) or oesophageal-gastric junction (EGJC) adenocarcinomas were treated with two courses of IC (irinotecan, 65 mg/m(2); cisplatin, 30 mg/m(2) on days 1 and 8 every 21 days) followed by IC/RT (daily radiotherapy-45 Gy-with concurrent IC: irinotecan, 65 mg/m(2), and cisplatin, 30 mg/m(2), on days 1, 8, 15, and 22). Resectability was reassessed after this treatment, and surgical resection was performed if feasible. The primary endpoint was the R0 resection rate after induction treatment. RESULTS Seventeen patients were included in the study (EGJC: 6; GC: 11). An R0 resection was achieved in only 5 patients (29%), and according to the design of the trial (Simon's optimal two-stage) accrual of patients was terminated after the first stage. No patient died during IC, whereas 3 patients (24%) died during IC/RT and one of 5 resected patients (20%) died during the first 30 days after resection. The median survival was 10.5 months, and the actuarial 2-year survival rate was 27%. CONCLUSIONS Induction IC followed by IC/RT showed poor efficacy and significant toxicity in patients with unresectable GC/EGJC.
