e15563 Background: Whether metastasectomy improves prognosis of gastric cancer patients with ovarian metastases (Krukenberg tumors) is not clear. In this study, we examined the survival benefit of metastasectomy combined with chemotherapy for treatment of synchronous Krukenberg tumors from gastric cancer and identified the prognostic factors. Methods: The subjects of this study were patients diagnosed as synchronous Krukenberg tumors of gastric origin in the period between December 2004 and December 2015. Patients were classified in accordance with treatment modality: metastasectomy group (metastasectomy combined with chemotherapy) and non-metastasectomy group (chemotherapy alone). Clinicopathological characteristics together with treatment records were investigated in detail and their relationship with survival outcomes was examined. Results: Out of a total of 103 patients, 54 (52.4%) underwent metastasectomy of Krukenberg tumors while 49 (47.6%) patients had chemotherapy alone. Overall survival (OS) in the metastasectomy group was significantly longer than that in the non-metastasectomy group (18.9 months vs. 12.4 months, respectively; P < 0.001). Metastasectomy (hazard ratio [HR] 0.486; 95% confidence interval [CI] 0.323–0.729; P < 0.001), signet ring cells (HR 1.938; 95% CI 1.182–3.175; P = 0.009), peritoneal carcinomatosis (HR 1.934; 95% CI 1.230–3.049; P = 0.004), expression of estrogen receptor-β (ER-β) (HR 0.404; 95% CI 0.251–0.648; P < 0.001), and progesterone receptor (PR) (HR 0.496; 95% CI 0.301–0.817; P < 0.001) were independent predictors of OS. Conclusions: Metastasectomy combined with chemotherapy showed an association with survival benefit in patients with synchronous Krukenberg tumors from gastric cancer. Metastasectomy, expression of ER-β and PR, peritoneal carcinomatosis, and signet ring cells were independent predictors of survival. Further prospective studies are warranted.

52 Background: Gastric cancer patient with ovarian metastasis, i.e. Krukenberg tumor, is common in clinical practice, but it is still uncertain whether surgical resection of ovarian metastasis could improve the outcome. This study aimed to explore the survival benefit of metastasectomy plus chemotherapy over chemotherapy alone in the treatment of Krukenberg tumors arising from gastric cancer and to identify prognostic factors. Methods: All patients who were diagnosed with gastric cancer and ovarian metastases between January 2005 and December 2014 were included in the current study. Patients were subdivided according to treatment modality: the metastasectomy group (metastasectomy plus chemotherapy) and the non-metastasectomy group (chemotherapy alone). The clinicopathological features and the treatment records were reviewed in detail and their association with survival were analyzed. Results: A total of 152 patients were identified, including 93 patients with synchronous ovarian metastasis and 59 patients with metachronous ovarian metastasis. Overall survival (OS) was significantly better in metastasectomy group relative to the non-metastasectomy group for patients with synchronous ovarian metastasis (19.0 months vs. 11.8 months; P < 0.001) and those with metachronous ovarian metastasis (24.6 months vs. 14.3 months; P = 0.02), respectively. Metastasectomy (hazard ration [HR] 0.486; 95% confidence interval [CI] 0.323–0.729; P < 0.001), peritoneal carcinomatosis (HR 1.934; 95% CI 1.230–3.049; P = 0.004), and expression status of ER-β (HR 0.404; 95% CI 0.251–0.648; P < 0.001) and PR (HR 0.496; 95% CI 0.301–0.817; P < 0.001) were independent predictors of OS. Conclusions: Metastasectomy plus chemotherapy was associated with survival benefits in patients with Krukenberg tumors from gastric cancer. Metastasectomy, peritoneal carcinomatosis, and expression status of ER-β and PR were independent prognostic factors for survival.

e16566 Background: The management of Krukenberg tumors from primary gastric cancer remains unclear and it is unknown if oophorectomy improves survival. The purpose of this study was to compare the overall survival (OS) of patients with ovarian metastases from gastric cancer treated with standard chemotherapy to chemotherapy and oophorectomy. Methods: Between January 2008 and August 2019, we retrospectively analyzed the clinicopathological features and treatment data of 97 patients with stage IV gastric cancer patients with ovarian metastases. Patients were categorized into two groups: Oophorectomy plus standard chemotherapy treatment vs. standard chemotherapy only (non-oophorectomy). The primary objective was to assess OS. Results: A total of 97 patients were identified. 37 (38.1%) patients had oophorectomy and 60 (61.9%) patients did not have oophorectomy. OS was better in the oophorectomy group relative to the non-oophorectomy group (37 months vs. 20 months; P= 0.0554). Survival from the time of diagnosis of ovarian metastases was significantly better in oophorectomy group relative to the non-oophorectomy group (26 months vs. 12 months; P= 0.0006). Conclusions: Our results showed that Oophorectomy in addition to systemic chemotherapy in this unique population seems to confer survival advantage in this retrospective analysis. Prospective evaluation is warranted.

The Impact

Introduction. The impact of preoperative BMI on surgical outcomes and long-term survival of gastric cancer patients was investigated in various reports with contrasting results.Materials & Methods. A total of 378 patients who underwent a surgical resection for primary gastric cancer between 1994 and 2011 were retrospectively studied. Patients were stratified according to BMI into a normal group (<25, group A), an overweight group (25–30, group B), and an obesity group (≥30, group C). These 3 groups were compared according to clinical-pathological characteristics, surgical treatment, and long-term survival.Results. No significant correlations between BMI and TNM (2010), UICC stage (2010), Lauren’s histological type, surgical results, lymph node dissection, and postoperative morbidity and mortality were observed. Factors related to higher BMI were male genderP<0.05, diabetesP<0.001, and serum blood proteinsP<0.01. A trend to fewer lymph nodes retrieved during gastrectomy with lymphadenectomy in overweight patients (B and C groups) was observed, although not statistically significant. There was no difference in overall survival or disease-specific survival between the three groups.Conclusion. According to our data, BMI should not be considered a significant predictor of postoperative complications or long-term result in gastric cancer patients.

Epigenetic Processes

We have performed mutational profiling of 25 genes involved in epigenetic processes on 135 gastric cancer (GC) samples. In total, we identified 79 somatic mutations in 49/135 (36%) samples. The minority (n = 8) of mutations was identified in DNA methylation/demethylation genes, while the majority (n = 41), in histone modifier genes, among which mutations were most commonly found in KMT2D and KMT2C. Somatic mutations in KMT2D, KMT2C, ARID1A and CHD7 were mutually exclusive (p = 0.038). Mutations in ARID1A were associated with distant metastases (p = 0.03). The overall survival of patients in the group with metastases and in the group with tumors with signet ring cells was significantly reduced in the presence of mutations in epigenetic regulation genes (p = 0.036 and p = 0.041, respectively). Separately, somatic mutations in chromatin remodeling genes correlate with low survival rate of patients without distant metastasis (p = 0.045) and in the presence of signet ring cells (p = 0.0014). Our results suggest that mutations in epigenetic regulation genes may be valuable clinical markers and deserve further exploration in independent cohorts.

Purpose. Although randomized trials suggest a survival benefit of adjuvant chemotherapy and radiation therapy (XRT) for gastric adenocarcinoma, its use in patients who undergo an extended lymphadenectomy is less clear. The purpose of this study was to determine if a survival benefit exists in gastric cancer patients who receive adjuvant XRT following resection with extended lymphadenectomy.Methods. The SEER registry was queried for records of patients with resected gastric adenocarcinoma from 1988 to 2007. Multivariable Cox regression models were used to assess independent prognostic factors affecting overall survival (OS) and disease-specific survival (DSS).Results. Of 15,060 patients identified, 3,208 (21%) received adjuvant XRT. Adjuvant XRT was independently associated with improved OS (HR 0.67, CI 0.64–0.71) and DSS (HR 0.69, CI 0.65–0.73) in stages IB through IV (M0). This OS and DSS benefit persisted regardless of the extent of lymphadenectomy. Furthermore, lymphadenectomy with >25 LN resected was associated with improved OS and DSS compared with <15 LN or 15–25 LN.Conclusion. This population-based study shows a survival benefit of adjuvant XRT following gastrectomy that persists in patients who have an extended lymphadenectomy. Furthermore, removal of >25 LNs results in improved OS and DSS compared with patients who have fewer LNs resected.

Signet-ring cell carcinoma (SRC) in advanced gastric cancer (GC) is often associated with more invasiveness and a worse prognosis than other cell types. The genetic alterations associated with gastric carcinogenesis in SRC are still unclear. In this study, 441 GC patients receiving curative surgery for GC between 2005 and 2013 were enrolled. The clinicopathological characteristics and genetic alterations of GC patients with and without SRC were compared. Among the 441 GC patients, 181 had SRC. For early GC, patients with SRC had more tumors located in the middle and lower stomach, more infiltrating tumors and better overall survival (OS) rates than those without SRC. For advanced GC, patients with SRC had more scirrhous type tumors, more PIK3CA amplifications, fewer microsatellite instability-high (MSI-H) tumors, more peritoneal recurrences and worse 5-year OS rates than those without SRC. For advanced GC with SRC, patients with peritoneal recurrence tended to have PD-L1 expression. For advanced GC without SRC, patients with liver metastasis tended to have PD-L1 expression, PI3K/AKT pathway mutations, TP53 mutations and MSI-H tumors. For advanced GC, PD-L1 expression was associated with peritoneal recurrence in SRC tumors, while non-SRC tumors with liver metastasis were likely to have PI3K/AKT pathway mutations, TP53 mutations and PD-L1 expression; immunotherapy and targeted therapy may be beneficial for these patients.
