Abstract
Gastric cancer remains a leading cause of cancer-related death worldwide, largely due to inadequate screening methods, late diagnosis, and limited treatment options. Liquid biopsy has emerged as a promising non-invasive approach for cancer screening and prognosis by detecting circulating tumor components like circulating tumor DNA (ctDNA) in the blood. Numerous gastric cancer-specific ctDNA biomarkers have now been identified. CtDNA analysis provides insight into genetic and epigenetic alterations in tumors, holding promise for predicting treatment response and prognosis in gastric cancer patients. This review summarizes current research on ctDNA biology and detection technologies, while highlighting clinical applications of ctDNA for gastric cancer diagnosis, prognosis, and guiding treatment decisions. Current challenges and future perspectives for ctDNA analysis are also discussed.

Abstract
Gastrointestinal cancers, including oesophageal, gastric and colorectal cancers (CRC) have high rates of disease recurrence despite curative resection. There are a number of recent studies that have investigated the use of circulating tumor DNA (ctDNA) for prognostic value in these cancers. We reviewed studies that had been published prior to March 2018 that assessed the prognostic values of ctDNA in patients with oesophageal and gastric cancers, gastrointestinal stromal tumors (GIST) and CRC. We identified 63 eligible clinical studies that focussed on recurrence and survival. Studies assessed investigated various ctDNA biomarkers in patients with different stages of cancer undergoing surgical resection, chemotherapy and no treatment. For oesophageal squamous cell carcinoma and oesophageal adenocarcinoma, methylation of certain genes such as APC and DAPK have been highlighted as promising biomarkers for prognostication, but these studies are limited and more comprehensive research is needed. Studies focusing on gastric cancer patients showed that methylation of ctDNA in SOX17 and APC were independently associated with poor survival. Two studies demonstrated an association between ctDNA and recurrence and survival in GIST patients, but more studies are needed for this type of gastrointestinal cancer. A large proportion of the literature was on CRC which identified both somatic mutations and DNA methylation biomarkers to determine prognosis. ctDNA biomarkers that identified somatic mutations were more effective if they were personalized based on mutations found in the primary tumor tissue, but ctDNA methylation studies identified various biomarkers that predicted increased risk of recurrence, poor disease free survival and overall survival. While the use of non-invasive ctDNA biomarkers for prognosis is promising, larger studies are needed to validate the clinical utility for optimizing treatment and surveillance strategies to reduce mortality from gastrointestinal cancers.

Abstract
BACKGROUND Gastrointestinal cancers constitute the third most common cancers worldwide. Tumor markers have long since been used in the postoperative surveillance of these malignancies; however, the true value in clinical practice remains undetermined. OBJECTIVE This study aimed to evaluate the clinical utility of three tumor markers in colorectal and esophagogastric cancer. METHODS A systematic review of the literature was undertaken to elicit the sensitivity, specificity, statistical heterogeneity and ability to predict recurrence and metastases for carcinoembryonic antigen (CEA), cancer antigen (CA) 19-9 and CA125. European surgeons were surveyed to assess their current practice and the characteristics of tumor markers they most valued. Data from the included studies and survey were combined in a cost-benefit trade-off analysis to assess which tumor markers are of most use in clinical practice. RESULTS Diagnostic sensitivity and specificity were ranked the most desirable characteristics of a tumor marker by those surveyed. Overall, 156 studies were included to inform the cost-benefit trade-off. The cost-benefit trade-off showed that CEA outperformed both CA19-9 and CA125, with lower financial cost and a higher sensitivity, and diagnostic accuracy for metastases at presentation (area under the curve [AUC] 0.70 vs. 0.61 vs. 0.46), as well as similar diagnostic accuracy for recurrence (AUC 0.46 vs. 0.48). CONCLUSIONS Cost-benefit trade-off analysis identified CEA to be the best performing tumor marker. Further studies should seek to evaluate new tumor markers, with investigation tailored to factors that meet the requirements of practicing clinicians.

Abstract
BACKGROUND The Italian Research Group for Gastric Cancer supports the practice of follow-up after radical surgery for gastric cancer. METHODS This multicenter, retrospective study (1998-2009) included patients with T1-4N0-3M0 gastric cancer who had undergone D2 gastrectomy and lymphadenectomy, with at least 15 lymph nodes examined, and who had developed recurrent disease. Timing and site of recurrence were correlated to the actual scheduled follow-up timing and modalities. RESULTS From eight centers, 814 patients with recurrent cancer and over 1,754 (46.4 %) patients undergoing gastrectomy were investigated (median follow-up 31 months). The most frequent sites of recurrence were local/regional lymph nodes (35.4 %), liver (24.3 %), peritoneum (30.3 %), lung (10.4 %) and intraluminal (7.5 %). Ninety-four percent of the recurrences were diagnosed within 2 years and 98 % within 3 years. Thoracoabdominal computed tomography (CT) scan and (18)F-fluoro-2-deoxy-D-glucose positron emission tomography (18-FDG-PET) detected more than 90 % of recurrences, abdominal ultrasound detected 70 % and tumor markers detected 40 %, while <10 % were identified by physical examination, chest X-ray, and upper gastrointestinal endoscopy. Twenty-six percent of patients with recurrence were treated, but only 3.2 % were treated with potentially radical intent. CONCLUSION Oncological follow-up after radical surgery for gastric cancer should be focused in the first 3 years, and based mainly on thoracoabdominal CT scan and 18-FDG-PET.

Abstract
BACKGROUND While clinicians routinely follow up gastric cancer patients after curative resection to detect recurrence, the effectiveness of regular follow-up has not been proven, and no consensus has been reached regarding follow-up programs. METHODS Of the 1,767 patients who underwent curative resection for gastric cancer from 2001 to 2004, 310 (17.5%) developed recurrence during follow-up. The oncologic effectiveness of follow-up was evaluated using recurrence detection rates during follow-up and survivals. Clinicopathologic characteristics, the detection tools used, and times lapsed between recurrence and previous examinations were also investigated. RESULTS Two hundred thirty-three (75.2%) of the 310 patients who developed recurrence were detected by regular follow-up (detected group). The frequencies of undifferentiated and diffuse-type recurrences were higher in patients with recurrence detected based on patient-initiated findings (undetected group) than in the detected group. Computed tomography and tumor markers were the first detection tools that yielded positive findings. Times between recurrence detection and previous examinations ranged from 2.8 to 5.3 months over the first 2 years. No difference in overall survival was found between the detected and undetected groups (log rank, P = 0.2). CONCLUSIONS The oncologic effectiveness of regular follow-up after curative resection for gastric cancer was found to be unsatisfactory. A large-scale randomized controlled trial is required to identify the effectiveness of regular follow-up in terms of its oncologic, functional, psychological, and economical aspects.

Abstract
BACKGROUND To date, guidelines for follow-up after curative resection in patients with gastric cancer have not been reported. Thus, most centers have managed the process according to institution-specific protocols. We investigated current follow-up practices after curative resection of gastric cancer using a nationwide survey in Korea, where gastric cancer is epidemic. METHODS From July to September 2007, questionnaires were sent out to 205 members of the Korean Gastric Cancer Association (KGCA). The questionnaire packet contained a covering letter, general information, and a questionnaire about follow-up schedules and methodologies. RESULTS Forty-six percent (96/205) of the members of the KGCA returned the survey. The majority of responders indicated that patients with early gastric cancer were followed up every 6 months (64.4%) for the first year, every 12 months (47.9%) for the next 4 years, and every 12 months (68.8%) from the fifth year after surgery on. For patients with advanced gastric cancer, follow-up studies were carried out every 3 months (43.8%) for the first year, every 6 months for the next 4 years, and every 12 months (75.0%) from the fifth year onward. After surgery, most responders used computed tomography for imaging, carcinoembryonic antigen (CEA) and carbohydrate antigen (CA)19-9 as tumor markers, and serum iron among follow-up measures. CONCLUSIONS Clinicians have a variety of approaches regarding the extent of follow-up and methodologies used after curative resection for gastric cancer. Therefore, a multicenter randomized trial will be needed to compare routine follow-up with intensive schedules. Our results could facilitate the design of such studies.

Abstract
The objective of this study was to assess the frequency and characteristics of false-positive results for tumor markers after curative gastrectomy for gastric cancer. Carcinoembryonic antigen and/or carbohydrate antigen 19-9 were periodically assessed for 168 patients who underwent curative gastrectomy. Cancer recurrence was observed for 17 (10.1%) patients and 151 (89.9%) were disease-free during the mean follow-up period of 23.1 months after the operation. The frequency of false-positive findings for tumor markers after gastrectomy was 14.3% (24/168) for all followed-up patients. Three different patterns of marker elevation were observed in the false-positive group. A false-positive finding for these markers was observed for patients with early-stage cancer and for those with chronic benign diseases, for example bronchitis, liver dysfunction, diabetes mellitus, and renal dysfunction. For most patients with false-positive findings for a marker a spontaneous decrease in the tumor marker was observed 1-2 months after the marker was first observed at a high level after the operation. Surgeons and oncologists should therefore keep in mind the high frequency of false-positive findings for tumor markers after curative gastrectomy for gastric cancer.

Abstract
Although there is broad agreement in the staging, classification, and surgery for gastric cancer, there is no consensus regarding follow-up after gastrectomy. Follow-up varies from investigations on clinical suspicion of relapse to intensive investigations to detect recurrences early, assuming that this improves survival and quality of life. Advanced gastric cancers recur mainly by locoregional recurrence or distant metastasis. Local recurrences detected at endoscopy or on computed tomography (CT) are invariably incurable. For early gastric cancers, endoscopy can detect new primaries, but the incidence of these tumors is low, and many thousands of procedures are required to detect each operable case. CT is much better at detecting liver metastasis and, although these are usually multiple and unresectable, there are several reports of good survival following liver resection for isolated metastasis. Tumor markers have been used with some success to detect subclinical recurrences and could be used to target more invasive or expensive procedures. In chemotherapy, many newer agents are promising significantly improved survival, but again, the evidence for greater benefit when administered prior to the patient becoming symptomatic is lacking. Overall, it appears that follow-up policy is as much decided by the wealth and facilities of the institution as by any significant evidence base. Although the early detection of recurrent cancer is an emotive issue for both patients and surgeons, considering the amount of time and money invested in follow-up, and the lack of evidence of efficacy, a randomized controlled trial of intensive follow-up is required.
