Epidemiology and prognostic nomogram for locally advanced gastric signet ring cell carcinoma:A population-based study

BACKGROUND Gastric signet ring cell carcinoma(GSRC)represents a specific subtype of gastric cancer renowned for its contentious epidemiological features,treatment principles,and prognostic factors.AIM To investigate the epidemiology of GSRC and establish an improved model for predicting the prognosis of patients with locally advanced GSRC(LAGSRC)after surgery.METHODS The annual rates of GSRC incidence and mortality,covering the years 1975 to 2019,were extracted from the Surveillance,Epidemiology,and End Results(SEER)database to explore the temporal trends in both disease incidence and mortality rates using Joinpoint software.The clinical data of 3793 postoperative LAGSRC patients were collected from the SEER database for the analysis of survival rates.The Cox regression model was used to explore the independent prognostic factors for overall survival(OS).The risk factors extracted were used to establish a prognostic nomogram.RESULTS The overall incidence of GSRC increased dramatically between 1975 and 1998,followed by a significant downward trend in incidence after 1998.In recent years,there has been a similarly optimistic trend in GSRC mortality rates.The trend in GSRC showed discrepancies based on age and sex.Receiver operating characteristic curves,calibration curves,and decision curve analysis for 1-year,3-year,and 5-year OS demonstrated the high discriminative ability and clinical utility of this nomogram.The area under the curve indicated that the performance of the new model outperformed that of the pathological staging system.CONCLUSION The model we established can aid clinicians in the early prognostication of LAGSRC patients,resulting in improved clinical outcomes by modifying management strategies and patient health care.

Effect of cetuximab plus FOLFOX4 regimen on clinical outcomes in advanced gastric carcinoma patients receiving evidence-based care

BACKGROUND Although chemotherapy is effective for treating advanced gastric carcinoma(aGC),it may lead to an adverse prognosis.Establishing a highly effective and low-toxicity chemotherapy regimen is necessary for improving efficacy and outcomes in aGC patients.AIM To determine the efficacy and safety of cetuximab(CET)combined with the FOLFOX4 regimen(infusional fluorouracil,folinic acid,and oxaliplatin)as firstline therapy for patients with aGC,who received evidence-based care(EBC).METHODS A total of 117 aGC patients who received EBC from March 2019 to March 2022 were enrolled.Of these,60 in the research group(RG)received CET+FOLFOX4 as first-line therapy,whereas 57 in the control group(CG)received FOLFOX4.The efficacy[clinical response rate(RR)and disease control rate(DCR)],safety(liver and kidney dysfunction,leukopenia,thrombocytopenia,rash,and diarrhea),serum tumor marker expression[STMs;carbohydrate antigen(CA)19-9,CA72-4,and carcinoembryonic antigen(CEA)],inflammatory indicators[interleukin(IL)-2 and IL-10],and quality of life(QOL)of the two groups were compared.RESULTS A markedly higher RR and DCR were observed in the RG compared with the CG,with an equivalent safety profile between the two groups.RG exhibited notably reduced CA19-9,CA72-4,CEA,and IL-2 levels following treatment,which were lower than the pre-treatment levels and those in the CG.Post-treatment IL-10 was statistically increased in RG,higher than the pre-treatment level and the CG.Moreover,a significantly improved QOL was evident in the RG.CONCLUSION The CET+FOLFOX4 regimen is highly effective as first-line treatment for aGC patients receiving EBC.It facilitates the suppression of STMs,ameliorates the serum inflammatory microenvironment,and enhances QOL,without increased adverse drug effects.

Risk evaluation of splenic hilar lymph node metastasis and survival analysis of patients with advanced gastric cancer

Background:There is no consensus regarding the influence of prophylactic no.10 lymph node(LN)dissection in patients with advanced gastric cancer(AGC).We aimed to evaluate whether patients with AGC could benefit from no.10 LN dissection and to explore the clinicopathological indicators of no.10 LN metastasis.Methods:We analyzed the data of 218 patients with AGC who underwent standard D2 lymphadenectomy(SD2;n=108)or modified D2 lymphadenectomy(MD2;n=110)between January 2017 and January 2021.In addition,we examined factors influencing no.10 LN metastasis in the SD2 group.Results:Differentiation,tumor location,and no.4 positive LNs were significantly correlated with no.10 LN metastasis(P<0.05).Borrmann classification,differentiation,depth of invasion,LN metastasis(N),and tumor size were found to correlate with survival in univariate analyses.Age,sex,extent of gastrectomy,tumor location,and extent of lymphadenectomy were not associated with survival(P>0.05).The median survival times were 72.23 and 68.56months for the SD2 andMD2 groups,respectively(P=0.635).Postoperative major morbidity and mortality rates were 37.96%and 3.70%in the SD2 group,and 23.64%and 1.82%in the MD2 group,respectively.Conclusions:Based on our findings,prophylactic no.10 lymphadenectomy may be recommended in patients with AGC who exhibit positive no.4 LN status,poor differentiation,and tumors located on the greater curvature.

Decline of serum CA724 as a probable predictive factor for tumor response during chemotherapy of advanced gastric carcinoma

Objective： To evaluate the predictive value of decline in the serum level of carbohydrate antigen 724 （CA724） on tumor response during the chemotherapy in patients with advanced gastric carcinoma （GC）. Methods= The serum CA724 level was determined by electrochemiluminescence immunoassay, while the objective response rate （eRR） was assessed according to response evaluation criteria in solid tumors （RECIST）. The association of the changes of serum concentration of CA724 with eRR was analyzed. Results： The eRR in CA724 （pretreatment serum level） high and low groups was 32.3% （20/62） and 52.8% （19/36）, respectively （P=0.045）. The relationship between the reduction of CA724 and the eRR was statistically significant （P=0.044）. Receiver operating characteristic （ROC） curve established the best cutoff value of the decrease ratio of CA724 as 20.5%. Conclusions： CA724 decline seems to indicate chemotherapy efficacy in patients with advanced GC, and an average drop of 20.5% in serum CA724 appears to predict the sensitivity to chemotherapy.

Fever as a first manifestation of advanced gastric adenosquamous carcinoma:A case report

Gastric adenosquamous carcinoma(ASC)is a rare type of gastric cancer.It is a mixed neoplasm,consisting of glandular cells and squamous cells.It is often diagnosed at an advanced stage,thus carrying a poor prognosis.We describe a case of a 73-year-old male,who presented with refractory fever and an intra-abdominal mass on imaging.He underwent a laparoscopic exploration followed by a successful totally laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer.Postoperative pathology revealed primary gastric ASC(T4aN0M0).The patient received adjuvant radiotherapy and chemotherapy with S1 and is alive 20mo after surgery without recurrence.This is the first case of advanced gastric ASC with fever as the initial presentation treated with totally laparoscopic total gastrectomy reported in the English literature.

Peritoneal cancer index is a prognostic indicator of survival in advanced gastric cancer with peritoneal carcinomatosis

Objective The peritoneal cancer index(PCI)has been used for the detailed evaluation of the peritoneal spread in tumors of a gynecologic origin and has been found to be a prognostic indicator of survival.The aim of this study was to identify the significance of the PCI in advanced gastric cancer(AGC)with peritoneal carcinomatosis(PC).Methods From 2010 to 2018,a retrospective analysis was carried out of 60 AGC patients with PC,including 21 patients with a PCI≤13 and 39 with a PCI>13.All patients were treated with both surgery and intraoperative peritoneal hyperthermic chemotherapy(IPHC).The performance status(Karnofsky performance status),age,sex,Borromann’s classification,differentiation,depth of invasion,lymph node metastasis,PCI,extent of gastrectomy,extent of lymph node dissection,and residual tumor volume were retrospectively evaluated and correlated to survival.Results The overall 5-year survival rate was 43%and mean survival was(54.47±4.53)months.The favorable clinical prognostic indicators of survival were Borromann’s classification,differentiation,depth of invasion,PCI,and residual tumor volume on univariate analyses(P<0.05).The Cox proportional regression hazard model showed that only the volume of residual tumor and PCI were associated with postoperative survival.The median survival time was 69.76 months for patients with a PCI≤13 and 39.96 months for patients with a PCI>13.There was a significant difference in survival rate between the two group(P=0.004).Postoperative major morbidity and mortality rates were 23.81%and 4.76%in the PCI≤13 group and 43.59%and 5.12%in the PCI>13 group,respectively.Conclusion The peritoneal spread in advanced gastric cancer with peritoneal carcinomatosis can be assessed in detail using the PCI.It is also a significant prognostic factor of survival and is useful in identifying subgroups.

THE PRESENT STATUS OF SURGICAL TREATMENT OF GASTRIC CANCER IN CHINA

Gastric cancer remains one of the leading malignancies in China. The history of modern surgical treatment of gastric cancer could be dated back to the early fifties with an overall 5-year survival rate of around 10%. Remarkable progress has been achieved ever since in terms of operability, resectability and 5-year survival rate which ranges now from 30% to over 50% after radical resection. In regard to problems and future perspective, apart from the effort which should be redoubled in increasing the detection rate of EGC, the need to popularize the new international TNM staging system, to carry out in-depth studies on the biological behavior of gastric cancers and the role of the spleen in the evolution of gastric cancer, and to include new potential adjuvant measures in the therapeutic regimen of AGC are emphasized.

晚期胃癌治疗进展

胃癌在全球最常见恶性肿瘤中排名第四位,是恶性肿瘤第二大死因;其发现多在晚期,已经失去了根治性手术机会。晚期胃癌治疗手段主要包括姑息性手术治疗、放疗、化疗、生物免疫治疗、中医药治疗。姑息性手术治疗主要用于减轻患者肿瘤负荷,或减少并发症的发生;放疗在局部晚期胃癌的治疗中具有一定的效用。化疗在晚期胃癌治疗中可发挥主导作用,对有症状的患者有始息性治疗效果。由FAX方案到ECF/DCF方案,再到REAL-2试验、ML17032、SPIRITS试验等几项里程碑式的随机性Ⅲ期临床研究结果的公布,关于晚期或转移性胃癌化疗的研究一直是关注的焦点,随着EOX、XP、S-1/CDDP、IF、FOLFOX、XELOX等化疗方案相继提出,晚期胃癌的临床疗效有了进一步提高,但目前尚未得到优势明显的标准治疗方案。胃癌的生物免疫治疗也逐渐成为研究热点,它是对手术和化、放疗的有益补充,但还不能作为主干性疗法。无论手术、放疗,或是化疗、生物免疫治疗,其在发挥疗效的同时,均具有明显的副作用。因此,采用中药内服外用、针灸推拿、心理干预等多种综合治疗手段,发挥中西医结合在缓解临床症状、对化、放疗减毒与增效、提高患者生存质量、预防肿瘤复发与转移、逆转肿瘤细胞多药耐药、治疗癌性腹水及癌性疼痛等方面的特色与优势,同样具有重要临床价值。
