Does gastric stump cancer really differ from primary proximal gastric cancer? A multicentre, propensity score matching-used, retrospective cohort study

BACKGROUND Although the location of proximal cancer of the remnant stomach is the same as that of primary proximal cancer of the stomach,its clinical characteristics and prognosis are still controversial.AIM To evaluate the clinicopathological features and prognosis factors of gastric stump cancer(GSC)and primary proximal gastric cancer(PGC).METHODS From January,2005 to December,2016,178 patients with GSC and 957 cases with PGC who received surgical treatment were enrolled.Patients in both groups underwent 1:1 propensity score matching analysis,and both clinical and pathological data were systematically collected for statistical purposes.Quality of RESULTS One hundred and fifty-two pairs were successfully matched after propensity score matching analysis.Of the 15 demographic and pathological variables collected,the analysis further revealed that the number of lymph nodes and positive lymph nodes were different prognostic and clinicopathological factors between PGC and GSC.Univariate and multivariate analyses showed that gender,differentiation degree and tumor-node-metastasis stage were independent risk factors for patients with GSC.Gender,vascular invasion,differentiation degree,depth of infiltration,positive lymph nodes,and tumor-node-metastasis stage were independent risk factors for patients with PGC.The 5-year overall survival and cancer-specific survival of patients with GSC were significantly lower than those in the PGC group,the scores for overall quality of life in the GSC-malignant group were lower than the GSC-benign,and the differences were statistically significant.CONCLUSION The differences in clinicopathological characteristics between GSC and PGC were clarified,and PGC had a better prognosis than GSC.

Prognostic factors and survival in patients with gastric stump cancer

AIM:To elucidate the clinicopathological characteristics and prognostic factors of gastric stump cancer(GSC).METHODS:The clinical data for 92 patients with GSC were collected at Fudan University Shanghai Cancer Center.The prognostic factors were analyzed with Cox proportional hazard models.RESULTS:GSC tended to occur within 25 years following the primary surgery,when the initial disease is benign,whereas it primarily occurred within the first15 years post-operation for gastric cancer.Patients with regular follow-up after primary surgery had a better survival rate.The multivariate Cox regression analysis revealed that Borrmann type?Ⅰ/Ⅱ(HR=3.165,95%CI:1.055-9.500,P=0.040)and radical resection(HR=1.780,95%CI:1.061-2.987,P=0.029)were independent prognostic factors for GSC.The overall 1-,3-,and 5-year survival rates of the 92 patients were78.3%,45.6%and 27.6%,respectively.The 1-,3-,and 5-year survival rates of those undergoing radical resection were 79.3%,52.2%,and 37.8%,respectively.The 5-year survival rates for stages?Ⅰ,Ⅱ,Ⅲ,andⅣwere 85.7%,47.4%,16.0%,and 13.3%,respectively(P=0.005).CONCLUSION:The appearance of GSC occurs sooner in patients with primary malignant cancer than in patients with a primary benign disease.Therefore,close follow-up is necessary.The overall survival of patients with GSC is poor,and curative resection can improve their prognosis.

Surgical management of gastric stump cancer:a report of 37 cases

Objective: To observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC. Methods: The clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical pTMN stage. Survival curves were traced by using Kaplan-Meier methods. Results: Most GSC (32/37) was detected in patients who had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=1 1.48, P＜0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage Ⅰ, 60% (3/5) for stage Ⅱ, 14.2% (1/7) for stage Ⅲ, and 0% (0/5) for stage Ⅳ respectively.The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0m vs 13.0m, xL2=36.31, P＜0.01), the median survival time of stage Ⅳ patients with radical resection was 23.8months. Conclusions: Without remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage Ⅳ GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth Ⅱ reconstruction procedure at 15-20 years.

Surgical resection of gastric stump cancer following proximal gastrectomy for adenocarcinoma of the esophagogastric junction

BACKGROUND Proximal gastrectomy(PG) is performed widely as a function-preserving operation for early gastric cancer located in the upper third of the stomach and is an important function-preserving approach for esophagogastric junction(EGJ)adenocarcinoma. The incidence of gastric stump cancer(GSC) after PG is increasing. However, little is known about the GSC following PG because very few studies have been conducted on the disease.AIM To clarify clinicopathologic features, perioperative complications, and long-term survival rates after the resection of GSC following PG.METHODS Data for patients with GSC following PG for adenocarcinoma of the EGJ diagnosed between January 1998 and December 2016 were retrospectively reviewed. Multivariate analysis was performed to identify factors associated with overall survival(OS). GSC was defined in accordance with the Japanese Gastric Cancer Association.RESULTS A total of 35 patients were identified. The median interval between the initial PGand resection of GSC was 4.9(range 0.7-12) years. In 21 of the 35 patients, the tumor was located in a nonanastomotic site of the gastric stump. Total gastrectomy was performed in 27 patients; the other 8 underwent partial gastrectomy. Postoperative complications occurred in 6 patients(17.1%). The tumor stage according to the depth of tumor invasion was T1 in 6 patients, T2 in3 patients, T3 in 9 patients, and T4 in 17 patients. Lymph node metastasis was observed in 18 patients. Calculated 1-, 3-, and 5-year OS rates were 86.5%, 62.3%,and 54.2%, respectively. Multivariate analysis showed advanced T stage to be associated with OS.CONCLUSION This study reveals the characteristics of GSC following PG for adenocarcinoma of the EGJ and suggests that a surgical approach can lead to a satisfactory outcome.

Appraisal of gastric stump carcinoma and current state of affairs

Gastric stump carcinoma,also known as remnant gastric carcinoma,is a malignancy arising in the remnant stomach following gastrectomy for a benign or malignant condition.Enterogastric reflux and preexisting risk factors in a patient with gastric cancer are the major contributors to the development of gastric stump carcinoma.The occurrence of gastric stump carcinoma is time-dependent and seen earlier in patients operated on for malignant rather than benign diseases.The tumor location is predominantly at the anastomotic site towards the stomach.However,it can occur anywhere in the remnant stomach.The pattern of lymph node involvement and the type of surgery required is distinctly different compared to primary gastric cancer.Gastric stump carcinoma is traditionally considered a malignancy with a dismal outcome.However,recent advances in diagnostic and therapeutic strategies have improved outcomes.Recent advances in molecular profiling of gastric stump carcinoma have identified distinct molecular subtypes,thereby providing novel therapeutic targets.Also,reports of gastric stump carcinoma following pancreatoduodenectomy and bariatric surgery highlight the need for more research to standardize the diagnosis,staging,and treatment of these tumors.The present review aims to provide an overview of gastric stump carcinoma highlighting the differences in clinicopathological profile and management compared to primary gastric carcinoma.

Management of duodenal stump fistula after gastrectomy for gastric cancer: Systematic review

AIM: To identify the most effective treatment of duodenalstump fistula(DSF) after gastrectomy for gastric cancer.METHODS: A systematic review of the literature was performed. Pub Med, EMBASE, Cochrane Library, CILEA Archive, BMJ Clinical Evidence and Up To Date databases were analyzed. Three hundred eighty-eight manuscripts were retrieved and analyzed and thirteen studies published between 1988 and 2014 were finally selected according to the inclusion criteria, for a total of 145 cases of DSF, which represented our group of study. Only patients with DSF after gastrectomy for malignancy were selected. Data about patients' characteristics, type of treatment, short and long-term outcomes were extracted and analyzed. RESULTS: In the 13 studies different types of treatment were proposed: conservative approach, surgical approach, percutaneous approach and endoscopic approach(3 cases). The overall mortality rate was 11.7% for the entire cohort. The more frequent complications were sepsis, abscesses, peritonitis, bleeding, pneumonia and multi-organ failure. Conservative approach was performed in 6 studies for a total of 79 patients, in patients with stable general condition, often associated with percutaneous approach. A complete resolution of the leakage was achieved in 92.3% of these patients, with a healing time ranging from 17 to 71 d. Surgical approach included duodenostomy, duodenojejunostomy, pancreatoduodenectomy and the use of rectus muscle flap. In-hospital stay of patients who underwent relaparotomy ranged from 1 to 1035 d. The percutaneous approach included drainage of abscesses or duodenostomy(32 cases) and percutaneous biliary diversion(13 cases). The median healing time in this group was 43 d. CONCLUSION: Conservative approach is the treatment of choice, eventually associated with percutaneus drainage. Surgical approach should be reserved for severe cases or when conservative approaches fail.

Extensive cutaneous metastasis of recurrent gastric cancer:A case report

BACKGROUND Cutaneous metastasis is a rare event associated with poor prognosis for gastric cancer and has been rarely reported in the literature.CASE SUMMARY A 69-year-old male patient who had undergone salvage gastrectomy and a few courses of adjuvant chemotherapy 3 mo earlier for recurrent gastric cancer developed widespread cutaneous metastases.Due to the patient’s intolerance to further adjuvant chemotherapy,he was placed in hospice care and expired 1 mo later.In the literature,gastric cancers are rarely reported as the primary malignancies for cutaneous metastasis.We,thus,provide an update on a case review published in 2014 by reviewing 10 more case reports dated from 2014 to 2020.The average age for the new group of patients was 59.4±18.88-years-old.Thirty percent of the patients presented with cutaneous lesions and advanced gastric cancer synchronously while 70%developed cutaneous metastases 1.3 years to 14 years after the initial treatment for primary gastric cancer.Eighty percent of the patients received either local excision or chemo±radiation therapy to treat their cutaneous metastases.CONCLUSION This report highlights cutaneous metastasis as a late and untreatable metastasis of gastric cancer.

泛影葡胺阴道残端标记物对宫颈癌术后放疗剂量的影响

探讨泛影葡胺阴道残端标记物对宫颈癌术后放疗剂量分布的影响。收集2022年7月至2023年7月甘肃省妇幼保健院/甘肃省中心医院行宫颈癌根治术后放疗且定位前放置泛影葡胺显影棉球标记阴道残端的患者12例,行容积旋转调强计划设计,得到计划PlanA,作为实际治疗计划。将被泛影葡胺显影的阴道残端区域的相对电子密度值替换为正常阴道壁的相对电子密度值,保持计划优化参数不变,重新计算得到Plan B。比较两组计划各评价指标及剂量分布的差异。结果显示:Plan B较PlanA组HI(1.048 vs.1.047)指数略差,CI(0.870 vs.0.868)指数更优;Plan B的PTV平均剂量(46.48 vs.46.47)和阴道残端剂量(47.14 vs.46.45)高于PlanA,直肠最小剂量(6.42 vs.6.49)低于PlanA。结果提示,泛影葡胺阴道残端标记物对剂量分布造成的影响可忽略不计。

Subtotal gastrectomy for gastric cancer

Although a steady decline in the incidence and mortality rates of gastric carcinoma has been observed in the last century worldwide,the absolute number of new cases/year is increasing because of the aging of the population. So far,surgical resection with curative intent has been the only treatment providing hope for cure;therefore,gastric cancer surgery has become a specialized field in digestive surgery. Gastrectomy with lymph node(LN) dissection for cancer patients remains a challenging procedure which requires skilled,well-trained surgeons who are very familiar with the fast-evolving oncological principles of gastric cancer surgery. As a matter of fact,the extent of gastric resection and LN dissection depends on the size of the disease and gastric cancer surgery has become a patient and "diseasetailored" surgery,ranging from endoscopic resection to laparoscopic assisted gastrectomy and conventional extended multivisceral resections. LN metastases are the most important prognostic factor in patients that undergo curative resection. LN dissection remains the most challenging part of the operation due to the location of LN stations around major retroperitoneal vessels and adjacent organs,which are not routinely included in the resected specimen and need to be preserved in order to avoid dangerous intra-and postoperative complications.Hence,the surgeon is the most important non-TMN prognostic factor in gastric cancer.Subtotal gastrectomy is the treatment of choice for middle and distal-third gastric cancer as it provides similar survival rates and better functional outcome compared to total gastrectomy,especially in early-stage disease with favorable prognosis.Nonetheless,the resection range for middle-third gastric cancer cases and the extent of LN dissection at early stages remains controversial.Due to the necessity of a more extended procedure at advanced stages and the trend for more conservative treatments in early gastric cancer,the indication for conventional subtotal gastrectomy depends on multiple variables.This review aims to clarify and define the actual landmarks of this procedure and the role it plays compared to the whole range of new and old treatment methods.

Neuroendocrine carcinoma of the gastric stump:A case report and literature review

We herein report a case of neuroendocrine carcinoma of the gastric stump found 47 years after Billroth II gastric resection for a benign gastric ulcer. A 74-yearold man was referred to another hospital with melena. Endoscopic examination revealed a localized ulcerative lesion at the gastrojejunal anastomosis. The diagnosis by endoscopic biopsy was neuroendocrine carcinoma. A total gastrectomy of the remnant stomach with D2 lymphadenectomy was performed at our hospital. The lesion invaded the subserosa, and metastasis was found in two of nine the lymph nodes retrieved. The lesion was positive for synaptophysin and chromogranin A, and the Ki-67 labeling index was 60%. The diagnosis of neuroendocrine carcinoma of the gastric stump was confirmed using World Health Organization 2010 criteria. Subsequently, the patient underwent one course of adjuvant chemotherapy with the etoposide plus cisplatin(EP) regimen; however, treatment was discontinued due to grade 3 myelosuppression. The patient showed lymph node metastasis in the region around the gastrojejunal anastomosis in the abdominal cavity 7 mo post-surgery. He then underwent radiotherapy and platinum-based combination chemotherapy; however, the disease progressed and liver recurrence was observed on follow-up computedtomography at 16 mo post-surgery. The patient then received chemotherapy with regimens used for the treatment of small cell lung cancer in first-and secondline settings. The patient died of disease progression 31 months after surgery.
