RESUMO

There are few reports of conversion surgery (CS) after nivolumab monotherapy because it is considered as a third-line standard chemotherapy for unresectable or recurrent gastric cancer. Here, we report a rare case of stage IV gastric cancer effectively treated with CS after nivolumab monotherapy as a third-line chemotherapy. A 73-year-old man was referred to our hospital with loss of appetite and abdominal discomfort. Stage IV gastric cancer with liver metastasis was diagnosed via upper gastrointestinal endoscopy and CT. Twelve courses of capecitabine, cisplatin, and trastuzumab were administered as the first-line treatment, 25 courses of paclitaxel plus ramucirumab as the second-line treatment, and 31 courses of nivolumab monotherapy as the third-line treatment. After 31 courses of nivolumab monotherapy, CT showed that the primary tumor shrank with no liver metastasis or ascites. Diagnostic laparoscopy was performed with no peritoneal dissemination (P0), and the peritoneal lavage cytology was negative (CY0). CS was performed with total gastrectomy and D2 lymph node dissection (R0 resection). The pathological diagnosis was U, Ant-Less, Type 2, 70 × 63 mm, poorly differentiated adenocarcinoma (ypT3N0M0 ypStage IIA). R0 resection was performed, and the histological response was grade 1a. The patient did not show recurrence for 9 months after CS.

RESUMO

BACKGROUND: Our previous report showed that surgical palliation maintained quality of life (QOL), improved solid food intake, and had an acceptable surgical safety among patients with malignant bowel obstruction (MBO) caused by advanced gastric cancer. This study performed a survival analysis stratified by the patients' QOL to elucidate its impact on survival. METHODS: Patients who underwent resection or bypass of the small intestine/colon or ileostomy/colostomy for bowel obstruction caused by peritoneal dissemination of gastric cancer were included. Validated instruments (EuroQoL-5 Dimensions) were used to assess QOL at baseline and 2 weeks, 1 month, and 3 months following surgical palliation. Postoperative improvement in oral intake was also evaluated using the Gastric Outlet Obstruction Scoring System (GOOSS). Univariate and multivariate survival analyses were performed using baseline characteristics and changes in QOL and GOOSS scores 2 weeks after surgery to determine prognostic factors. RESULTS: We enrolled 60 patients with a median survival time of 6.64 (95% CI 4.76-10.28) months. Patients who received postoperative chemotherapy and had lower baseline C-reactive protein (CRP) levels, higher baseline albumin levels, better baseline EuroQoL-5 Dimensions (EQ-5D) scores, and improved oral intake after palliative surgery exhibited significantly better survival. Multivariate analysis identified postoperative chemotherapy, lower baseline CRP levels, and improved oral intake as independent prognostic factors. CONCLUSIONS: The current study revealed that baseline QOL and postoperative QOL changes did not affect survival. Moreover, improved oral intake, lower baseline CRP levels, and postoperative chemotherapy were significant prognostic factors in patients who underwent palliative surgery for advanced gastric cancer with MBO.

RESUMO

BACKGROUND/AIM: The chemokine receptors C-X-C chemokine receptor type 4 (CXCR4) and C-C chemokine receptor type 7 (CCR7) play an important role in the invasion and metastasis of cancer. This study investigated the relationship between relative expression of CXCR4 and CCR7 mRNA, clinicopathological factors, and outcomes in patients with colorectal cancer (CRC). PATIENTS AND METHODS: We studied 202 patients who underwent surgery for CRC. The expression levels of CXCR4 and CCR7 mRNA in cancerous tissue were measured using quantitative real-time reverse-transcriptase polymerase chain reaction. RESULTS: High CCR7 mRNA expression levels in CRC tissues were positively associated with tumour size and were more frequently associated with cancer of the rectum than of the colon. Moreover, outcomes were significantly poorer in patients with high CCR7 mRNA expression than in those with low expression. On multivariate Cox regression analysis, a higher CCR7 mRNA expression level was a significant independent predictor of poorer overall survival in patients with CRC. CONCLUSION: Overexpression of CCR7 mRNA may be a useful independent prognostic factor in patients with CRC.

RESUMO

PURPOSE: Despite improvements in surgical techniques and devices and perioperative care of gastric cancer (GC), the rate of postoperative complications still has not decreased. If patients at high risk for postoperative complications could be identified early using biomarkers, these complications might be reduced. In this study, we investigated usefulness of the preoperative Glasgow Prognostic Score (GPS) as a predictive factor for complications after surgery in patients with stage II/III GC. METHODS: This study retrospectively analyzed the outcomes of 424 patients who underwent curative surgery for pathological stage II/III GC from February 2007 to July 2019 at a single center. The GPS was assessed within 4 days before surgery. To identify independent risk factors for postoperative complications, univariate and multivariate analyses were performed using a Cox proportional hazards model. RESULTS: The numbers of patients with a GPS of 0, 1, and 2 were 357, 55, and 12, respectively. The rate of complications after surgery was significantly higher among patients with a GPS of 1 or 2 than among patients with a GPS of 0 (p = 0.008). Multivariate analysis identified a GPS of 1 or 2 as an independent predictive factor for postoperative complications (p = 0.037). CONCLUSION: The preoperative GPS may be a useful predictive factor for postoperative complications in patients with stage II/III GC. Being aware of the risk of complications after surgery as indicated by the GPS before surgery may promote safe and minimally invasive surgery that we expect will improve outcomes in patients with a GPS of 1 or 2.

RESUMO

PURPOSE: FGFR2 amplification is associated with poor prognosis in advanced gastric cancer and its subclonal heterogeneity has been revealed. Here, we examined whether circulating tumor DNA (ctDNA) was useful for detecting FGFR2 amplification and co-occurring resistance mechanisms in advanced gastric cancer. EXPERIMENTAL DESIGN: We assessed genomic characteristics of FGFR2-amplified advanced gastric cancer in a nationwide ctDNA screening study. We also analyzed FGFR2 amplification status in paired tissue and plasma samples with advanced gastric cancer. In addition, we examined patients with FGFR2-amplified advanced gastric cancer identified by ctDNA sequencing who received FGFR inhibitors. RESULTS: FGFR2 amplification was more frequently detected by ctDNA sequencing in 28 (7.7%) of 365 patients with advanced gastric cancer than by tissue analysis alone (2.6%-4.4%). FGFR2 amplification profiling of paired tissue and plasma revealed that FGFR2 amplification was detectable only by ctDNA sequencing in 6 of 44 patients, which was associated with a worse prognosis. Two patients in whom FGFR2 amplification was detected by ctDNA sequencing after tumor progression following previous standard chemotherapies but not by pretreatment tissue analysis had tumor responses to FGFR inhibitors. A third patient with FGFR2 and MET co-amplification in ctDNA showed a limitation of benefit from FGFR inhibition, accompanied by a marked increase in the MET copy number. CONCLUSIONS: ctDNA sequencing identifies FGFR2 amplification missed by tissue testing in patients with advanced gastric cancer, and these patients may respond to FGFR inhibition. The utility of ctDNA sequencing warrants further evaluation to develop effective therapeutic strategies for patients with FGFR2-amplified advanced gastric cancer.

RESUMO

BACKGROUND/AIM: Cancer stem cells (CSCs) are reported to associated with cancer metastasis, relapse, and chemoresistance. This study examined the clinical significance of the expression of two CSC markers, the transporter associated with antigen processing 1 (TAP1) and the Delta-like 4 (DLL4) protein, in patients with locally advanced GC. PATIENTS AND METHODS: This study was performed using samples obtained from 413 pathological stage II/III GC patients after curative gastrectomy. We examined TAP1 and DLL4 expression using immunohistochemical analysis with tissue microarray and examined the association between TAP1 or DLL4 expression, clinicopathological factors and survival. RESULTS: High TAP1 expression was associated with better overall survival compared to low TAP1 expression (p=0.004). Furthermore, in multivariate analysis, high TAP1 expression was defined as a predictive factor for good survival. There was no significant difference between DLL4 expression and clinicopathological features and overall survival. CONCLUSION: TAP1 expression may be a useful prognostic marker in patients with locally advanced GC.

RESUMO

BACKGROUND/AIM: This study aimed to evaluate the prognostic significance of PLA2G2A expression in patients with locally advanced gastric cancer (GC). PATIENTS AND METHODS: PLA2G2A expression levels in cancerous tissue specimens and adjacent normal mucosa obtained from 134 patients with stage II/III GC who received adjuvant chemotherapy with S-1 after curative resection were measured using real-time quantitative polymerase chain reaction. Subsequently, the associations of PLA2G2A expression with clinicopathological features and survival were evaluated. RESULTS: No association was observed between clinicopathological features and PLA2G2A expression levels. Overall survival was significantly longer in patients with high PLA2G2A expression levels (p=0.022). Multivariate analysis revealed that PLA2G2A expression was a significant, independent prognostic factor (hazard ratio=0.136; 95% confidence interval=0.0185-0.992; p=0.049). CONCLUSION: PLA2G2A mRNA expression may serve as a useful prognostic marker in patients with locally advanced GC who receive curative surgery and adjuvant chemotherapy with S-1.

RESUMO

PURPOSES: The spread of coronavirus disease 2019 (COVID-19) has affected socioeconomic and healthcare systems in many countries. Accordingly, many individuals may have canceled their annual health-check programs, including esophagogastroduodenoscopy, which would have resulted in lower numbers of newly diagnosed patients with gastric cancer in comparison to other times. METHODS: Questionnaires were distributed to 62 hospitals every week from May 2020 to August 2020 (total 744) through mailing lists of the Stomach Cancer Study Group of the Japan Clinical Oncology Group. The number of patients with gastric cancer and hospital systems during the COVID-19 pandemic were surveyed. RESULTS: In total, 74% (551 out of 744) of the questionnaires were answered and analyzed. In early May, approximately 50% of hospitals had to restrict surgical slots due to the COVID-19 pandemic. However, they gradually loosened the restrictions thereafter. The number of gastrectomies was < 80% that of the same period in the previous year, and hospitals in Tokyo were seriously affected by a 50% decrease in the number of gastrectomies. CONCLUSIONS: The number of gastrectomies was lower than that in the previous year. Further multi-center follow-up studies are required to evaluate the long-term effects of COVID-19 on the clinical outcomes of patients with gastric cancer.

RESUMO

BACKGROUND: The lymph node (LN) ratio (LNR) has been proposed as a sensitive prognosticator in patients with esophageal squamous cell carcinoma (ESCC), especially when the number of LNs harvested is insufficient. We investigated the association between the LNR and survival in patients with locally advanced ESCC who received neoadjuvant chemotherapy (NAC) and explored whether the LNR is a prognosticator in these patients when stratified by their response to NAC. METHODS: We retrospectively reviewed 199 locally advanced ESCC patients who received curative resection after NAC between January 2011 and December 2019. The predictive accuracy of the adjusted X-tile cut-off values for LNR of 0 and 0.13 was compared with that in the Union for International Cancer Control pathological N (UICC pN) categories. The association between survival rate and clinicopathological features was examined. RESULTS: Multivariate analysis identified that the LNR was an independent risk factor for recurrence-free survival [RFS; hazard ratio (HR) 6.917, p < 0.001] and overall survival (OS) (HR 4.998, p < 0.001). Moreover, even when stratified by response to NAC, the LNR was a significant independent risk factor for RFS and OS (p < 0.001). The receiver operating characteristic curves identified that the prognostic accuracy of the LNR tended to be better than that of the UICC pN factor in all cases and responders. CONCLUSION: The LNR had a significant prognostic value in patients with locally advanced ESCC, including in those who received NAC.

RESUMO

BACKGROUND/AIM: The changes of dietary intake (DI) after gastrectomy have not been objectively reported. It has not been clear how much DI loss is experienced after total gastrectomy (TG) in comparison to after distal gastrectomy (DG). This study quantified the changes of DI after gastrectomy, and clarified how much DI loss is experienced after TG. PATIENTS AND METHODS: This was a prospective observational study. Patients who underwent gastrectomy for gastric cancer were enrolled. The DI loss was evaluated at 1 and 3 months postoperatively. RESULTS: Thirty-three patients underwent TG, and 117 patients underwent DG. The median %DI loss of the overall study population at 1 and 3 months after surgery was -9.3% and -3.6%. The median %DI loss at 1 and 3 months postoperatively was -15.6% and -5.3% in TG group, -8.9% and -3.3% in DG group (p=0.10 and 0.49, respectively). CONCLUSION: The patients experienced DI loss of approximately 10% at 1 month after gastrectomy. Patients who received TG tended to show a greater %DI loss at 1 month postoperatively.

RESUMO

AIM: To compare the mid-term oncological results between patients with low rectal cancer who underwent minimally invasive laparoscopic surgery (MILS) and those who underwent open surgery (OS). PATIENTS AND METHODS: Overall, 262 matched patients who underwent primary resection for low rectal cancer between 2000 and 2019 were divided into MILS (n=131; n=107, conventional laparoscopic surgery; n=24, robotic surgery) and OS (n=131) groups. The short- and mid-term outcomes were compared. RESULTS: Similar baseline characteristics were noted. The operative time was longer and blood loss was lesser in the MILS group; the conversion rate was 3.8%. The incidence of postoperative complications was similar. The 2-year cumulative incidence of local recurrence was noted to be much lower in the MILS group (1.9%) than in the OS group (8.4%). MILS had a significantly low hazard ratio (0.208, p=0.036). CONCLUSION: MILS has potential benefits in reducing local recurrence of low rectal cancer.

RESUMO

BACKGROUND: Patients with peritoneal dissemination of gastric cancer have poor oral intake caused by malignant bowel obstruction (MBO). Palliative surgery has often been undertaken to improve quality of life (QOL), but few prospective studies on palliative surgery in this patient population have been published. PATIENTS AND METHODS: We prospectively investigated the significance of palliative surgery using patient-reported QOL measures. Patients underwent palliative surgery by small intestine/colon resection or small intestine/colon bypass or ileostomy/colostomy for MBO. The primary endpoint was change in QOL assessed at baseline, 14 days, 1 month, and 3 months following palliative surgery using the Euro QoL Five Dimensions (EQ-5D™) questionnaire and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire gastric cancer module (QLQ-STO22). Secondary endpoints were postoperative improvement in oral intake and surgical complications. RESULTS: Between April 2013 and March 2018, 63 patients were enrolled from 14 institutions. The mean EQ-5D™ utility index baseline score of 0.6 remained consistent. Gastric-specific symptoms mostly showed statistically significant improvement from baseline. Forty-two patients (67%) were able to eat solid food 2 weeks after palliative surgery and 36 patients (57%) tolerated it for 3 months. The rate of overall morbidity of ≥ grade III according to the Clavien-Dindo classification was 16% (10 patients) and the 30-day postoperative mortality rate was 3.2% (2 patients). CONCLUSIONS: In patients with MBO caused by peritoneal dissemination of gastric cancer, palliative surgery did not improve QOL while improving solid food intake, with an acceptable postoperative morbidity and mortality rate.

RESUMO

BACKGROUND/AIM: Stanniocalcin2 (STC2) is associated with proliferation, invasion, and metastasis in various cancers. We examined the clinical significance of STC2 mRNA expression in patients with colorectal cancer (CRC). PATIENTS AND METHODS: Relative expression levels of STC2 mRNA in CRC tissues and corresponding normal mucosa obtained from 202 patients were measured using quantitative real-time reverse transcriptase-polymerase chain reaction. RESULTS: Expression of STC2 mRNA was higher in the cancer tissue than in the adjacent normal mucosa. STC2 mRNA expression in cancer tissues was associated with tumour size, liver metastasis, venous invasion, and lymph node metastasis. High expression of STC2 mRNA was significantly associated with poorer postoperative survival (p=0.0003). Multivariate analysis showed that high expression of STC2 mRNA was an independent predictor of postoperative survival. CONCLUSION: High expression of STC2 mRNA in CRC tissue may be a useful prognostic marker in patients with CRC.

RESUMO

BACKGROUND: Omentectomy is considered an essential part of curative gastrectomy for locally advanced gastric cancer (GC), albeit without solid evidence. We conducted a randomized phase II trial (the TOP-G trial) comparing omentectomy and omentum preservation for gastric cancer. This report describes the short-term findings regarding the trial's secondary endpoints. METHODS: The trial protocol was submitted to the University Hospital Medical Information Network Clinical Trials Registry ( http://www.umin.ac.jp/ctr/ : UMIN000005421). The key eligibility criteria were histologically confirmed cT2-4a and N0-2 gastric adenocarcinoma. Short-term surgical outcomes, including morbidity and mortality, were compared between the omentectomy group (group A, control arm) and the omentum-preserving surgery group (group B, test arm). All procedures were performed via an open approach. Based on a non-inferiority margin of 7%, statistical power of 0.7, and type I error of 0.2, the sample size was set to 250 patients. RESULTS: A total of 251 patients were eligible and randomized (group A: 125 patients, group B: 126 patients) between April 2011 and October 2018. After excluding patients who had peritoneal metastasis or laparotomy history, safety outcomes were analyzed for 247 patients. Group A had a significantly longer median operation time (225 min vs. 204 min, p = 0.022) and tended to have greater median blood loss (260 mL vs. 210 mL p = 0.073). The incidences of morbidity were similar and < 10% in both groups (8% vs. 9%, p = 1.000). There was no mortality in either group. CONCLUSIONS: Operative risk was generally similar between omentectomy and omentum-preserving surgery for locally advanced gastric cancer.

RESUMO

Some authors have suggested that a relationship exists between gastrectomy for gastric cancer and metabolic bone disorders. However, few studies have investigated metabolic bone disorders after gastrectomy for gastric cancer in detail. Thus, we reviewed the findings of our recent prospective study and those of other reports on this subject. Osteoporosis and osteomalacia have been observed after gastrectomy and appear to be caused by reduced food intake and absorption, and steatorrhea. Moreover, the incidence of fracture is high after gastrectomy, although subtotal or total gastrectomy and reconstruction for gastric cancer have not been identified as significant risk factors for decreased bone mineral density (BMD). Recently, we reported that the BMD decreased significantly within 12 months after gastrectomy for gastric cancer in both male and female patients, but there was no significant gender-related difference in the rate of change in BMD. More than 1 year after gastrectomy, the steep decrease in the BMD stabilized and normal levels of 1,25(OH)2 vitamin D3 were maintained, despite the lack of precursor for 1,25(OH)2 vitamin D3 synthesis after gastrectomy. Alendronate therapy might be effective and prevent postgastrectomy metabolic bone disorders; however, the optimal treatment and prevention strategy for this bone disorder has not been delineated.

RESUMO

BACKGROUND: Naples prognostic score (NPS) is a scoring system based on albumin, cholesterol concentration, lymphocyte-to-monocyte ratio, and neutrophil-to-lymphocyte ratio reflecting host systemic inflammation, malnutrition, and survival for several malignancies. This study was designed to assess the prognostic significance of NPS in patients with locally advanced esophageal squamous cell carcinoma (ESCC) and to compare its prognostic accuracy with that of other systemic inflammatory and nutritional index. METHODS: We retrospectively examined 165 patients with locally advanced ESCC who underwent neoadjuvant therapy followed by curative resection between January 2011 and September 2019. Patients were divided into three groups based on their NPS before neoadjuvant therapy (Group 0: NPS = 0; Group 1: NPS = 1-2; Group 2: NPS = 3-4). We compared the clinicopathological characteristics and survival rates among the groups. RESULTS: The 5-year recurrence-free survival (RFS) and overall survival (OS) rates were significantly different between the groups (P < 0.001). The NPS was superior to other systemic inflammatory and nutritional index for predicting prognoses, as determined using area under the curves (P < 0.05). Multivariate analysis demonstrated that the NPS was a significant predictor of poor RFS (Group 1: hazard ratio [HR] 1.897, P = 0.049; Group 2: HR 3.979, P < 0.001) and OS (Group 1: HR 2.152, P = 0.033; Group 2: HR 3.239, P = 0.006). CONCLUSIONS: The present study demonstrated that NPS was an independent prognostic factor in patients with locally advanced ESCC and more reliable and accurate than the other systemic inflammatory and nutritional index.

RESUMO

BACKGROUND/AIM: We hypothesised that the prognostic nutrition index (PNI) is useful for evaluating host immunity and response to immune checkpoint inhibitors. We investigated the effect of PNI on nivolumab monotherapy efficacy in advanced or recurrent gastric cancer (GC) or gastro-oesophageal junction cancer (GOC) patients. PATIENTS AND METHODS: We retrospectively examined 110 patients, divided them into a high-PNI group and a low-PNI group, and compared treatment efficacy, adverse events (AEs), and survival between the groups. RESULTS: Median overall survival (OS) was significantly longer in the high-PNI group than in the low-PNI group (205 vs. 109 days; p<0.001). Multivariate analysis revealed that low PNI was an independent risk factor for OS (hazard ratio=2.398; 95% confidence interval=1.384-4.154; p=0.002). The overall response rate and frequency of AEs were not significantly different between the groups. CONCLUSION: PNI could be a useful prognostic factor in GC or GOC patients undergoing nivolumab monotherapy.
