Gaber CE, Sarker J, Abdelaziz AI, Okpara E, Lee TA, Klempner SJ, Nipp RD. Pathologic complete response in patients with esophageal cancer receiving neoadjuvant chemotherapy or chemoradiation: A systematic review and meta-analysis. Cancer Med 2024; 13:e7076. [PMID: 38457244 PMCID: PMC10923050 DOI: 10.1002/cam4.7076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 02/11/2024] [Accepted: 02/20/2024] [Indexed: 03/10/2024] Open
Abstract
BACKGROUND Neoadjuvant chemoradiation and chemotherapy are recommended for the treatment of nonmetastatic esophageal cancer. The benefit of neoadjuvant treatment is mostly limited to patients who exhibit pathologic complete response (pCR). Existing estimates of pCR rates among patients receiving neoadjuvant therapy have not been synthesized and lack precision. METHODS We conducted an independently funded systematic review and meta-analysis (PROSPERO CRD42023397402) of pCR rates among patients diagnosed with esophageal cancer treated with neoadjuvant chemo(radiation). Studies were identified from Medline, EMBASE, and CENTRAL database searches. Eligible studies included trials published from 1992 to 2022 that focused on nonmetastatic esophageal cancer, including the gastroesophageal junction. Histology-specific pooled pCR prevalence was determined using the Freeman-Tukey transformation and a random effects model. RESULTS After eligibility assessment, 84 studies with 6451 patients were included. The pooled prevalence of pCR after neoadjuvant chemotherapy in squamous cell carcinomas was 9% (95% CI: 6%-14%), ranging from 0% to 32%. The pooled prevalence of pCR after neoadjuvant chemoradiation in squamous cell carcinomas was 32% (95% CI: 26%-39%), ranging from 8% to 66%. For adenocarcinoma, the pooled prevalence of pCR was 6% (95% CI: 1%-12%) after neoadjuvant chemotherapy, and 22% (18%-26%) after neoadjuvant chemoradiation. CONCLUSIONS Under one-third of patients with esophageal cancer who receive neoadjuvant chemo(radiation) experience pCR. Patients diagnosed with squamous cell carcinomas had higher rates of pCR than those with adenocarcinomas. As pCR represents an increasingly utilized endpoint in neoadjuvant trials, these estimates of pooled pCR rates may serve as an important benchmark for future trial design.

Abstract
BACKGROUND The pathological complete response (ypCR) rate following neoadjuvant chemotherapy for advanced gastric cancer remains low and lacks a universally accepted treatment protocol. Immunotherapy has achieved breakthrough progress. CASE SUMMARY We report two female patients with gastric cancer defined as clinical stage cT4N1-2M0. Detection of mismatch repair protein showed mismatch repair function defect, and perioperative treatment with programmed death protein 1 inhibitor combined with S-1+oxaliplatin achieved ypCR. Surprisingly, the patients underwent clinical observation after surgery but developed different degrees of metastasis at ~6 mo after surgery. CONCLUSION PD-1 inhibitor combined with chemotherapy provides a more strategic choice for comprehensive perioperative treatment of gastric cancer.

Abstract
BACKGROUND Gastric cancer is the fifth most common cancer worldwide. One of the chemotherapy agents, taxanes is important in increasing patients' survival. The purpose of this study is to assess the efficacy of taxane-based drugs versus non-taxanes in neoadjuvant chemotherapy in non-metastatic gastric adenocarcinoma (GA) in Iranian patients. MATERIALS AND METHODS In a historical cohort method, 65 patients between 18 and 75 years old who suffered from non-metastatic GA were included. Nineteen and 21 and 25 patients, had undergone DCF (docetaxel, cisplatin, 5fluorouracil) and FLOT (5fluorouracil, leucovorin, oxaliplatin, docetaxel) and FOLFOX6 (oxaliplatin, leucovorin, 5fluorouracil) regimens, respectively, between 2018 and 2021. Survival criteria consisting of progression-free survival (PFS), overall survival (OS), progression rate, and mortality rate were evaluated using the Kaplan-Meier method, in a three-year follow-up period. RESULTS The majority of patients were male (72.3%), with a median age of 65 years. Most of the patients had lesions with tumor, node, metastasis (TNM) stage IIIb (27.7%) and poor differentiated pathological grade (49.2%). OS time had a significant correlation with the low TNM stage (P = 0.01), well-differentiated pathological grade (P = 0.005), and FLOT vs. FOLFOX protocol (20.3 vs. 12.2 months, respectively. P =0.04). FLOT regimen had significantly better OS survival vs. DCF regimen (20.3 vs. 15.4 months, respectively, P = 0.03). No significant correlation was observed between survival criteria and other factors like gender, age, past medical history, Karnofsky scale, and tumor location in the stomach. The taxane-based arm (sum of DSF and FLOT) had no superiority over the non-taxane arm in survival criteria. CONCLUSION FLOT protocol, as a taxane-based regimen had better survival compared to FOLFOX protocol in neoadjuvant chemotherapy in gastric non-metastatic adenocarcinoma.

Dis Esophagus 2022; 36:6712698. [PMID: 36151055 PMCID: PMC9885734 DOI: 10.1093/dote/doac058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 07/31/2022] [Accepted: 08/11/2022] [Indexed: 02/02/2023]
Abstract
Locally advanced esophageal adenocarcinomas (EACs) are treated with multimodal therapy, namely surgery, neoadjuvant chemotherapy (NAC) or chemoradiotherapy (CRT) depending on patient and tumor level factors. Yet, there is little consensus on choice of the optimum systemic therapy. To compare the pathological complete response (pCR) after FLOT, non-FLOT-based chemotherapy and chemoradiotherapy regimes in patients with EACs. A systematic review of the literature was performed using MEDLINE, EMBASE, the Cochrane Review and Scopus databases. Studies were included if they had investigated the use of chemo(radio)therapy regimens in the neoadjuvant setting for EAC and reported the pCR rates. A meta-analysis of proportions was performed to compare the pooled pCR rates between FLOT, non-FLOT and CRT cohorts. We included 22 studies that described tumor regression post-NAC. Altogether, 1,056 patients had undergone FLOT or DCF regimes, while 1,610 patients had received ECF or ECX. The pCR rates ranged from 3.3% to 54% for FLOT regimes, while pCR ranged between 0% and 31% for ECF/ECX protocols. Pooled random-effects meta-meta-analysis of proportions showed a statistically significant higher incidence of pCR in FLOT-based chemotherapy at 0.148 (95%CI: 0.080, 0.259) compared with non-FLOT-based chemotherapy at 0.074 (95%CI: 0.042, 0.129). However, pCR rates were significantly highest at 0.250 (95%CI: 0.202, 0.306) for CRT. The use of enhanced FLOT-based regimens have improved the pCR rates for chemotherapeutic regimes but still falls short of pathological outcomes from CRT. Further work can characterize clinical responses to neoadjuvant therapy and determine whether an organ-preservation strategy is feasible.

Prognostic Relevance of Weight and Weight Loss during Multimodal Therapy for Oesophagogastric Tumours. Curr Oncol 2022; 29:2706-2719. [PMID: 35448195 PMCID: PMC9028417 DOI: 10.3390/curroncol29040221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/21/2022] [Accepted: 04/01/2022] [Indexed: 11/24/2022] Open
Abstract
The prognostic meaning of weight loss (WL) during standard treatment for operable oesophagogastric cancer is still unclear. The aim of this study is to analyse the prognostic effect of WL during perioperative chemotherapy (PC) for gastric cancer (GC) and oesophageal adenocarcinomas (OAC). We retrospectively analysed data from 128 patients (pts) with GC and OAC who underwent surgery in the context of multimodal treatment with PC. We collected data on WL during different steps of therapy together with other histopathologic and demographic information. We analysed the effects on overall survival (OS) and disease-free survival (DFS). Results: Pts with WL ≥ 5% during neoadjuvant chemotherapy exhibited significantly worse OS compared with pts with WL < 5% (median OS: 23.6 months [95% CI: 4.4−42.9] vs. 63.5 months [95% CI: 50.7−76.2], p = 0.007) and DFS (median DFS: 12.5 months [95% CI: 2.9−22.1] vs. 63.5 months [95% CI: 31.6−95.4], p = 0.016). Pts with WL ≥ 14% during the whole treatment exhibited significantly worse OS compared with pts with WL < 14% (median OS: 43.7 months [95% CI: 13.2−74.2] vs. not reached, p = 0.028) and DFS (median DFS: 34.3 months [95% CI: 14.0−54.5] vs. not reached, p = 0.038). Conclusion: WL patterns during neoadjuvant chemotherapy and during the whole treatment correlate with a significantly worse prognosis in operated pts with curative GC or OAC in the context of a multimodal treatment with PC. A validation of this prognostic effect in prospective studies is warranted.

Abstract
The problems with anticancer therapy are resistance and toxicity. From 3000 Cisplatin derivatives tested as antitumor agents, most of them have been rejected, due to toxicity. The aim of current study is the comparison of therapeutic combinations of the currently applied in clinical practice: Cisplatin, Carboplatin, Oxaliplatin, Nedaplatin, Lobaplatin, Heptaplatin, and Satraplatin. The literature data show that the strategies for the development of platinum anticancer agents and bypassing of resistance to Cisplatin derivatives and their toxicity are: combination therapy, Pt IV prodrugs, the targeted nanocarriers. The very important strategy for the improvement of the antitumor effect against different cancers is synergistic combination of Cisplatin derivatives with: (1) anticancer agents—Fluorouracil, Gemcitabine, Cytarabine, Fludarabine, Pemetrexed, Ifosfamide, Irinotecan, Topotecan, Etoposide, Amrubicin, Doxorubicin, Epirubicin, Vinorelbine, Docetaxel, Paclitaxel, Nab-Paclitaxel; (2) modulators of resistant mechanisms; (3) signaling protein inhibitors—Erlotinib; Bortezomib; Everolimus; (4) and immunotherapeutic drugs—Atezolizumab, Avelumab, Bevacizumab, Cemiplimab, Cetuximab, Durvalumab, Erlotinib, Imatinib, Necitumumab, Nimotuzumab, Nivolumab, Onartuzumab, Panitumumab, Pembrolizumab, Rilotumumab, Trastuzumab, Tremelimumab, and Sintilimab. An important approach for overcoming the drug resistance and reduction of toxicity of Cisplatin derivatives is the application of nanocarriers (polymers and liposomes), which provide improved targeted delivery, increased intracellular penetration, selective accumulation in tumor tissue, and enhanced therapeutic efficacy. The advantages of combination therapy are maximum removal of tumor cells in different phases; prevention of resistance; inhibition of the adaptation of tumor cells and their mutations; and reduction of toxicity.

Abstract
Perioperative chemotherapy is the standard of care for patients undergoing curative resection for gastroesophageal adenocarcinoma. However, less than 50% of patients complete postoperative chemotherapy, and the added benefit to preoperative chemotherapy remains unclear. The aim of this study was to compare disease-free and overall survival (DFS and OS) in patients with perioperative chemotherapy to those who received preoperative chemotherapy only. In addition, a current literature overview is included. This multicenter, retrospective case series included 124 patients with gastroesophageal adenocarcinoma undergoing potentially curative resection and receiving pre- or perioperative chemotherapy between 2006 and 2010. Histopathological, demographic, clinical, and survival data were used to identify the impact of perioperative vs. preoperative chemotherapy on DFS and OS. Patients with perioperative chemotherapy had significantly improved DFS and OS (median DFS 28.0 months; 95%CI 0–62.4 vs. 19.0 months; 95%CI 10.5–27.5; p = 0.008 and median OS 35.7 months; 95%CI 0–73.6 vs. 19.2 months; 95%CI 7.8–30.4; p = 0.002). However, in contrast to patients with tumor-free lymph nodes at the time of resection, patients with positive lymph node status did not significantly benefit from additional postoperative chemotherapy in subgroup analysis. Further studies are encouraged to investigate optimal adjuvant treatment strategies for primary chemotherapy-resistant patients.

Abstract
Purpose This paper is aimed at comparing the short-term efficacy of the combination of docetaxel, oxaliplatin, and capecitabine (DOX) with the combination of oxaliplatin and capecitabine (XELOX) as neoadjuvant chemotherapy regimens for the treatment of patients with resectable gastric or gastroesophageal junction adenocarcinoma. Methods A total of 300 patients aged 20-60 years with resectable gastric or gastroesophageal junction adenocarcinoma who were evaluated with cT3/4Nany were randomly assigned into 3 groups: DOX group (n = 100, treated with neoadjuvant DOX plus adjuvant XELOX), XELOX group (n = 100, treated with perioperative XELOX), and surgery group (n = 100, treated with adjuvant XELOX). Results A total of 93, 92, and 95 patients were enrolled in the DOX, XELOX, and surgery groups, respectively. The pathological complete response (pCR) rate was 16.1% in the DOX group and 4.3% in the XELOX group (P = 0.008). There were 56 (61.3%) patients in the DOX group who presented with surgical complications, 22 (23.9%) patients in the XELOX group, and 37 (38.9%) patients in the surgery group. The most common grade 3-4 adverse events in these three groups were neutropenia (32.3%, 30.4%, and 21.1%), leucopenia (21.5%, 22.8%, and 15.8%), nausea (15.1%, 16.3%, and 12.6%), and fatigue (10.8%, 7.6%, and 8.4%). Conclusions Neoadjuvant DOX is an effective and feasible regimen and might represent an option for young and middle-aged patients with locally advanced, resectable gastric or gastroesophageal junction adenocarcinoma.

Abstract
Most gastric cancer and gastroesophageal junction carcinoma (GEJ) patients are already in the advanced stage at the time of diagnosis. Thus, the probability of radical gastrectomy is low, and surgical treatment alone has a poor prognosis due to the high recurrence rate. In order to reduce the recurrence and distant metastasis after surgery, there have been many attempts made to improve the perioperative treatment of advanced localized gastric cancer, but no uniform criteria exist. Over recent years, immunotherapy has revolutionized cancer treatment, and immune checkpoint inhibitors (ICIs) have shown excellent efficacy across various types of tumors, becoming a potential treatment after surgery, chemotherapy, radiotherapy, and targeted therapy. However, the efficacy of single-agent ICIs for gastric cancer is still unsatisfactory. As comprehensive, chemotherapy-based treatment has become the standard care for locally advanced gastric cancer, exploring combination treatment with immune checkpoint inhibitors (ICIs) may be valuable to improving survival outcomes. Here, we report a 66-year-old male with dysphagia diagnosed with GEJ and was defined as clinical stage (cT4N2M0) and Siewert type II, characterized as mismatch repair proficient (pMMR) and programmed cell death ligand-1 (PD-L1) negative; surprisingly, with anti-PD-1 antibody plus SOX (S-1: a combination of tegafur, gimeracil, and oteracil+ oxaliplatin) as perioperative therapy, the patient achieved pathological complete remission (pCR), which indicates that the addition of ICIs to chemotherapy as a perioperative comprehensive treatment might provide a promising strategy option for GEJ. In addition, we review the current status of perioperative comprehensive treatment, in hope that this may provide some reference value for clinical decision-making.

Operative Results and Perioperative Morbidity After Intensified Neoadjuvant Chemotherapy with FLOT for Gastroesophageal Adenocarcinoma Impact of Intensified Neoadjuvant Treatment. J Gastrointest Surg 2021; 25:58-66. [PMID: 32040809 DOI: 10.1007/s11605-019-04511-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Accepted: 12/29/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Perioperative treatment is the standard of care in Western Europe for locally advanced gastric cancer (GC) and adenocarcinoma of the gastroesophageal junction (GEJ). Intensified neoadjuvant treatment within the NeoFLOT trial proved to be safe and effective. Yet, the influence of such intensification with 6 cycles of FLOT in the neoadjuvant setting has not been analyzed regarding its possible impact on perioperative results. MATERIALS AND METHODS A total of 537 patients were enrolled in this study; of whom, 132 had followed a standard neoadjuvant protocol (CTx), 356 had not received any neoadjuvant treatment (NoCTx), and 49 patients had undergone an intensified chemotherapy within the NeoFLOT trial (IntCTx) with 6 cycles of FLOT (5-FU, leucovorin, oxaliplatin, docetaxel) every 2 weeks. RESULTS Our results reveal no significant difference in perioperative morbidity or mortality with regard to the neoadjuvant treatment. Postoperative bleeding and hematoma occurred less frequently in the IntCTx group compared to the NoCTx and the CTx groups (2.0% vs. 5.33% vs. 5.1%). Postoperative lymph fistulas were slightly more frequent in the IntCTx group (4.1% vs. 0.3% vs. 1.6%). Patients treated within the NeoFLOT trial had a higher risk for blood transfusions (OR 5.5; 95%-KI, 2.49-12.19), whereas patients without neoadjuvant therapy had the longest ICU stay (mean 8.3 vs. CTx 4.5 vs. IntCTx 6.7 days). CONCLUSION The results of the current study indicate that also an intensification of neoadjuvant chemotherapy with 6 preoperative cycles of FLOT does not significantly increase perioperative complications. Thus, prolonged neoadjuvant chemotherapy with FLOT is safe for patients with locally advanced GC or GEJ tumors.

Pattern of Recurrence and Patient Survival after Perioperative Chemotherapy with 5-FU, Leucovorin, Oxaliplatin and Docetaxel (FLOT) for Locally Advanced Esophagogastric Adenocarcinoma in Patients Treated Outside Clinical Trials. J Clin Med 2020; 9:jcm9082654.

Abstract
Background: The 5-FU, Leucovorin, Oxaliplatin and Docetaxel (FLOT) protocol provides superior oncologic results compared to other perioperative chemotherapeutic protocols for the treatment of non-metastatic esophagogastric cancer (EGAC). Survival and the pattern of recurrence of EGAC after FLOT and curative tumor resection are analyzed in a collective of patients treated outside clinical trials. Methods: Two-hundred-seventy-seven patients with EGAC (cT3-4 and/or cN+) were treated with perioperative FLOT-chemotherapy plus curative surgery between 2009 and 2018. Data were analyzed retrospectively from a prospective database. Results: Two-hundred-twenty-eight patients were included in the analysis. Postoperative in-hospital mortality was 2%. The median survival was 61–months, and median recurrence-free survival was 42 months. Multivariate analysis identified postoperative nodal status and T-stage as independent predictors of improved overall and recurrence-free survival. Administration of adjuvant chemotherapy failed to be significant for overall survival but was an independent predictor of recurrence-free survival. Recurrence occurred after a median of 9 months (range 1–46 months). Eighty-nine percent of recurrence occurred during the first 24 months. The rate of local recurrence was low. After surgery for gastric cancer, the major recurrence site was peritoneal carcinomatosis (56%), while esophageal cancer recurred mostly as metastasis to distant organs (78%). The specific site of recurrence had no impact on overall survival time. Conclusion: Real-life application of FLOT shows oncologic results comparable to clinical trials. Recurrence after FLOT and surgery for EGAC occurs predominantly early within the first two years after surgery and in the form of distant organ metastasis for esophageal tumors or peritoneal carcinomatosis for gastric tumors.

Abstract
Gastric cancer (GC) is a common tumor with a low 5-year survival rate. The chemokine receptor 4 (CXCR4) protein contributes to the progression and prognosis of GC, but the relationship between CXCR4 and immune infiltration, somatic copy number alteration (SCNA), tumor purity, tumor mutation burden (TMB), cytolytic activity (CYT), and drug sensitivity in GC is poorly understood. This study aimed to systematically explore the role of CXCR4 in GC. Microarray and RNA-seq data were collected from the Gene Expression Omnibus and The Cancer Genome Atlas. Our analysis shows that CXCR4 is correlated with various types of immune cells. Patients with high CXCR4 expression had a higher fraction of B cells and CD8+ T cells, and a lower fraction of CD4+ T cells. In addition, high CXCR4 expression was associated with more advanced tumor stage, worse prognosis and higher stromal score, immune score, and cytolytic activity (P < 0.05). High CXCR4 expression also correlated with lower tumor purity and TMB. In summary, our analyses suggest that CXCR4 may affect the progression and prognosis of GC by influencing immune infiltration, TMB, CYT, tumor purity, and drug sensitivity.

Abstract
IMPORTANCE Patients with locally advanced gastroesophageal adenocarcinoma (ie, stage ≥T3 and/or node positive) have high rates of recurrence despite surgery and adjunctive perioperative therapies, which also have high toxicity profiles. Evaluation of pharmacogenomically dosed perioperative gFOLFIRINOX (fluorouracil, leucovorin, oxaliplatin, and UGT1A1 genotype-directed irinotecan) to optimize efficacy while limiting toxic effects may have value. OBJECTIVE To evaluate the coprimary end points of margin-negative (R0) resection rates and pathologic response grades (PRGs) of gFOLFIRINOX therapy among patients with locally advanced gastroesophageal adenocarcinoma. DESIGN, SETTING, AND PARTICIPANTS This single-group phase 2 trial, conducted at 2 academic medical centers from February 2014 to March 2019, enrolled 36 evaluable patients with locally advanced adenocarcinoma of the esophagus, gastroesophageal junction, and gastric body. Data analysis was conducted in May 2019. INTERVENTIONS Patients received biweekly gFOLFIRINOX (fluorouracil, 2400 mg/m2 over 46 hours; oxaliplatin, 85 mg/m2; irinotecan, 180 mg/m2 for UGT1A1 genotype 6/6, 135 mg/m2 for UGT1A1 genotype 6/7, or 90 mg/m2 for UGT1A1 genotype 7/7; and prophylactic peg-filgastrim, 6 mg) for 4 cycles before and after surgery. Patients with tumors positive for ERBB2 also received trastuzumab (6-mg/kg loading dose, then 4 mg/kg). MAIN OUTCOMES AND MEASURES Margin-negative resection rate and PRG. RESULTS A total of 36 evaluable patients (27 [78%] men; median [range] age, 66 [27-85] years; 10 [28%] with gastric body cancer; 24 [67%] with intestinal-type tumors; 6 [17%] with ERBB2-positive tumors; 19 [53%] with UGT1A1 genotype 6/6; 16 [44%] with genotype 6/7; and 1 [3%] with genotype 7/7) were enrolled. Of these, 35 (97%) underwent surgery; 1 patient (3%) died after completing neoadjuvant chemotherapy while awaiting surgery. Overall, R0 resection was achieved in 33 of 36 patients (92%); 2 patients (6%) with linitis plastica achieved R1 resection. Pathologic response grades 1, 2, and 3 occurred in 13 patients (36%), 9 patients (25%), and 14 patients (39%), respectively, and PRG 1 was observed in 11 of 24 intestinal-type tumors (46%). Median disease-free survival was 30.1 months (95% CI, 15.0 months to not reached), and median overall survival was not reached (95% CI, 8.3 months to not reached). There were no differences in outcomes by UGT1A1 genotype group. A total of 38 patients, including 2 (5%) with antral tumors, were evaluable for toxic effects. Grade 3 or higher adverse events occurring in 5% or more of patients during the perioperative cycles included diarrhea (7 patients [18%]; 3 of 19 patients [16%] with genotype 6/6; 2 of 16 patients [13%] with genotype 6/7; 2 of 3 patients [67%] with genotype 7/7), anemia (2 patients [5%]), vomiting (2 patients [5%]), and nausea (2 patients [5%]). CONCLUSIONS AND RELEVANCE In this study, perioperative pharmacogenomically dosed gFOLFIRINOX was feasible, providing downstaging with PRG 1 in more than one-third of patients and an R0 resection rate in 92% of patients. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02366819.

Systematic review and meta-analysis of docetaxel perioperative chemotherapy regimens in gastric and esophagogastric tumors. Sci Rep 2019; 9:15806.

Abstract
FLOT regimen became the standard perioperative treatment in several centers around the world for esophagogastric tumors despite concerns about toxicity. In addition, FLOT has never been compared with other docetaxel-based regimens. To address this question, we conducted a systematic review of PubMed, Embase and Web of Science including prospective or retrospective studies of docetaxel based perioperative regimen in gastric and esophagogastric tumors. Data regarding chemotherapy regimens, efficacy and toxicity were extracted. Outcomes were compared using a random effects model. Of 548 abstracts, 16 were considered eligible. Comparing the studies with meta-analysis we can see that the regimens are similar in terms of pathological complete response, resection rate, progression free survival and overall survival in one year, without significant heterogeneity. The meta-regression of docetaxel dose failed to show any association with dose ranging between 120–450 mg/m². Regarding the toxicity of the regimens it is noted that the regimens are quite toxic (up to 50–70% of grade 3–4 neutropenia). The results of this meta-analysis with a combined sample size of more than 1,000 patients suggest that docetaxel perioperative regimens are equivalent in outcomes. Prospective trials addressing modified regimens should be performed to provide less toxic strategies and be applicable to all patients.

Abstract
In the multimodality treatment strategy for gastric cancer, chemotherapy has an important role in conferring survival benefit. For the last three decades, great progress has been achieved in adjuvant and palliative chemotherapy. Powerful combination regimens using doublet or triplet cytotoxic agents have been developed and new molecular targeted drugs, including trastuzumab and ramucirumab, have been introduced in clinical practice. These advances have resulted from the accumulation of many clinical trials. A well-designed phase III trial can change standard treatment; however, such a trial is hard to complete due to its huge cost and need to recruit many patients. Some co-operative groups have actively made efforts at fundraising and patient recruitment, which can make implementation of high-quality and large-scale phase III trials possible. This review summarizes the development of chemotherapy for gastric cancer with focus on co-operative groups around the world, considering effective treatment developments in gastric cancer. We studied 11 active co-operative groups, including six in Europe, two in the United States, and three in Japan, that have completed one or more phase III trials cited in the major guidelines. Each co-operative group had its own characteristics and contributed to the establishment of standard treatment in each region. International collaboration in the development of gastric cancer treatment may be difficult due to regional differences in standards of care, particularly for resectable gastric cancer. Whereas, intergroup collaboration within each region is a reasonable method to effectively develop treatments for resectable and advanced gastric cancer.

Abstract
Efficacy of the combination of oxaliplatin, 5-fluorouracil and radiotherapy on rectal cancer in elderly patients was investigated. Seventy-three elderly patients with rectal cancer confirmed by histopathological examination were randomly divided into 3 groups: oxaliplatin group (25 cases): intravenous infusion of oxaliplatin; fluorouracil group (24 cases): intravenous infusion of fluorouracil; combination group (24 cases), intravenous infusion of oxaliplatin and fluorouracil. All patients were treated with radiotherapy, and efficacy and safety were evaluated after 2 courses of treatment. MTT assay was used to observe the inhibitory effects of the proliferation of human rectal cancer cells. Cell proliferation and sensitization ratios were compared. After 2 courses of treatment, there was no difference in complete remission (CR), partial remission (PR), stable disease (SD), progression disease (PD) and disease control rate (DCR). Remission rate (RR) was higher in the combination group than that in the oxaliplatin and the fluorouracil groups (P<0.05), and there was no difference between the oxaliplatin and the fuorouracil group (P>0.05). Incidence of neutropenia in the combination group was higher than that in the fluorouracil group (P<0.05). OD values of the combination group were lower than those of the oxaliplatin and the fluorouracil groups (P<0.05). Proliferation ability of SW837 cells of the combination group was significantly lower than that of the oxaliplatin and the fluorouracil groups (P<0.05). Intragroup comparison of sensitization ratio showed that sensitization ratios of three groups of cells at 24, 48 and 72 h were all higher than those at 12 h (P<0.05). The combination of oxaliplatin and 5-fluorouracil is safe and effective in the treatment of rectal cancer in elderly patients, and it can be used for sensitization of radiotherapy. So it should be popularized in clinical practices.

Abstract
Apatinib (Jiangsu HengRui Medicine Co. Ltd), a vascular endothelial growth factor receptor 2 (VEGFR-2) tyrosine kinase inhibitor, has been proven to be safe and to significantly prolong survival in advanced chemotherapy-refractory gastric cancer. This study aimed to assess and compare the efficacy and safety of apatinib combined with chemotherapy with that of chemotherapy alone as second- or higher-line treatment in patients with advanced and metastatic gastric or those with metastatic gastroesophageal junction adenocarcinoma (mGC).Patients with chemotherapy-refractory mGC at Jiangsu Cancer Hospital & Research Institute were prospectively enrolled and assigned into 2 groups at a 2:1 ratio. The first group (combination group) comprised patients with combination treatment (apatinib + chemotherapy), while the second group comprised patients treated with chemotherapy alone (chemotherapy group). The dose of apatinib was 500 mg/d, and the chemotherapy regimens were based on fluoropyrimidine, platinum, and paclitaxel or irinotecan. The primary end points were progression-free survival (PFS).Between November 2014 and December 2016, 175 patients were enrolled. PFS was significantly improved in the combination group compared with that in the chemotherapy group (8.5 months [95% confidence interval [CI], 6.45-10.54] vs 7.0 months [95% CI, 5.12-8.88] P = .021; hazard ratio (HR): 0.645 [95% CI: 0.429-0.969] P = .035). The disease control rate (DCR) was also higher in the combination group than that in the chemotherapy group (58.4% vs 41.9%, P = .041). Moreover, the incidence of Grade 3 to 4 hand-foot syndrome, proteinuria, and hypertension was significantly different between the 2 groups. Combined therapy (P = .040) and metastatic sites <2 (P = .008) were the independent prognostic factors for disease progression.Compared with chemotherapy alone, the addition of apatinib to chemotherapy could better improve PFS and DCR with an acceptable safety profile for mGC refractory to 1 or more line of prior chemotherapy.

Abstract
INTRODUCTION Perioperative epirubicin, cisplatin and 5-FU or capecitabine (ECF/X) chemotherapy is recognised as a standard of care for patients with resectable gastroesophageal adenocarcinoma; however, there is limited evidence regarding its use in older patients. The aims of this study were to assess the effectiveness and tolerability of perioperative ECX chemotherapy in patients aged ≥70 years-old (group 1) compared with a younger population (group 2), and to assess differences in the histology of these groups. METHODS 212 patients in our centre were treated with neoadjuvant chemotherapy for potentially resectable gastroesophageal adenocarcinoma between February 2009 and January 2014. Seventy patients (33.0%) were aged ≥70 years-old and 142 (67.0%) patients were aged under 70 years-old. RESULTS In group 1, 57 (81.4%) of patients underwent intended radical oesophagectomy or gastrectomy compared with 106 (74.6%) in group 2 (p = 0.271). The median overall survival was 35.3 months in group 1 and 30.1 months in group 2, respectively (p = 0.281). The rates of grade 3 to 4 non-haematological toxicity in groups 1 and 2 were 38.6% and 26.8%, respectively (p = 0.079). There was no difference in groups 1 and 2 regarding: pT stage, tumour grade, circumferential resection margin involvement, tumour regression grade, vascular invasion, lymphatic invasion and perineural invasion. 74.4% patients in group 2 were node-positive following chemotherapy and surgery compared with 48% in group 1 (p = 0.0015). DISCUSSION Selected older adults with gastroesophageal adenocarcinoma treated with perioperative ECX chemotherapy have similar overall survival and likelihood of having radical surgery as younger patients.

Abstract
In the current German S3 guidelines surgical treatment is not recommended for metastatic gastric cancer or metastatic adenocarcinoma of the esophagogastric junction; however, in routine practice the indications can be extended so that there may be occasions in which radical surgical intervention for specific individuals may be appropriate as part of a multimodal therapy with curative intent. This article presents the scientific rationale of such an approach based on the available literature considering modern, multimodal therapy concepts including criteria to be met for radical surgery. Currently only retrospective trials and limited current meta-analysis data are available for justifying surgical treatment for metastatic adenocarcinoma. The recently published initial results of the FLOT-3 study identified a patient subgroup that benefits from a resection even though metastasis has occurred. Whether surgical therapy will become an integral part of the treatment of limited metastatic adenocarcinoma of the stomach and esophagus in the future, has to be demonstrated by large prospective randomized studies, such as the RENAISSANCE/FLOT-5 study.

Abstract
BACKGROUND Data on the typical time point of occurrence of anastomotic leak (AL) after esophagectomy for esophageal cancer are currently scarce. Therefore, the usefulness of routine radiocontrast agent studies (RRCS) for testing proper healing of the anastomosis after esophagectomy remains unclear. Furthermore, preferred available tools to diagnose postoperative AL and therapeutic options are still under debate. METHODS We present a retrospective analysis of 328 consecutive patients who underwent esophagectomy for esophageal cancer between 2005 and 2015. A RRCS has been performed to date in our center on the fifth postoperative day (POD), before returning to normal oral intake. RESULTS In total, 49 of 328 patients developed AL after esophagectomy (15%). A total of 11 patients (23%) developed AL before the RRCS and 34 patients (69%) after an unremarkable RRCS; and 4 patients (8%) with AL were diagnosed by RRCS, resulting in overall sensitivity of 16%. The median time point of occurrence of AL was POD 9, the majority of AL (84%) occurred between POD 1 and 19. Computed tomography led to the diagnosis of AL in 41% of patients. The most frequent therapy of AL was stenting in 47% of patients. Endoscopic vacuum therapy was used in 4 patients. CONCLUSIONS The majority of AL occurred within the first 3 weeks after esophagectomy without a typical time point. In our series, RRCS on the fifth POD had a low sensitivity of 16%. Therefore, standardized RRCS and fasting till the examination cannot be generally recommended. In case of clinical suspicion of AL, computed tomography of the chest and abdomen with oral contrast agent should be performed, followed by endoscopy. Endoscopic stent placement remains the standard therapy of AL in our center. Endoscopic vacuum therapy evolves as it is an interesting alternative therapeutic option and can be combined with stenting in selected cases.

Abstract
OPINION STATEMENT Two cycles of neoadjuvant cisplatin and fluoropyrimidine (CF) and 6 cycles of perioperative CF with or without epirubicin are an evidence-based approach in operable esophageal and esophagogastric junctional adenocarcinomas. Three-drug regimens with anthracycline or taxane are associated with significantly higher tumor regression rates, with an expected increase in toxicity. In order to achieve an R0 resection and consequently a survival advantage, in selected patients having a risk of a threatened margin or incomplete resection, chemotherapy might be continued beyond 2 cycles if a response has been demonstrated. In metastatic setting, multidrug combination regimens have demonstrated a significant survival benefit when compared to single-agent regimes. A three-drug regimen should be considered for fit patients and/or when a response is required for symptom control. The expected increase in toxicity needs to be carefully considered and discussed with patients. The choice to use a taxane in first-line setting may limit the options of second-line treatment to irinotecan-containing regimens and also precludes the use of anthracyclines in the first line. For this reason, we prefer to reserve taxane-based therapy for the second-line setting.

Routine Radiologic Contrast Agent Examination After Gastrectomy for Gastric Cancer Is Not Useful. J Gastrointest Surg 2017; 21:801-806. [PMID: 28205124 DOI: 10.1007/s11605-017-3384-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Accepted: 01/31/2017] [Indexed: 01/31/2023]
Abstract
Many studies have showed that routine upper gastrointestinal contrast agent examinations (RCE) for testing the patency of the anastomosis after esophagectomy or the stapler line after sleeve gastrectomy cannot be recommended due to low sensitivity. However, the clinical value of RCE after gastrectomy for gastric cancer remains unclear. We have retrospectively analyzed the clinical course of 377 consecutive patients who underwent gastrectomy for gastric cancer in our institution between 2005 and 2015. To date, we have performed a RCE on the fifth postoperative day before removal of the nasogastric tube and return to oral intake. In total, we have observed 14 anastomotic leaks (AL) (4%) after oncologic gastrectomy. Four AL (28.6%) occurred before the scheduled RCE on the fifth postoperative day (POD) and 7 (50%) late AL after POD 5. Three patients (21.4%) without any clinical symptoms were diagnosed by the RCE. Sensitivity of RCE was 50%. A significant percentage of patients with AL was diagnosed by computed tomography (CT) of the abdomen (50%). The standard therapy for AL after gastrectomy was endoscopic stent placement (n = 11), including three cases of stenting after surgical revision. Based on our data, we cannot recommend a RCE after gastrectomy for gastric cancer. The majority of AL occurs before or after a RCE and the sensitivity of the examination is low. In case of clinical suspicion of AL, a CT scan (with oral contrast agent) should be performed. In unclear cases, endoscopy is the preferable method providing the option of direct treatment.

Abstract
BACKGROUND Perioperative chemotherapy improves the prognosis of patients with locoregionally advanced resectable gastric and gastro-esophageal junction adenocarcinoma. Nevertheless, only 50% of operated patients could receive the postoperative component chemotherapy. An exclusive preoperative chemotherapy is therefore an interesting strategy. We report the clinical course of patients with operable gastric and gastroesophageal junction adenocarcinoma treated with an intention of exclusive preoperative chemotherapy. METHODS The medical records of all consecutive patients with an operable gastric or gastroesophageal junction adenocarcinoma and treated with an intention of exclusive preoperative chemotherapy were analysed. RESULTS Between 1999 and 2014, 90 eligible patients were identified. Fifty-eight patients (64%) presented with clinical T3-T4 tumour and 63 (70%) had a lymph node involvement. Eighty (90%) patients were treated with 4 cycles of preoperative chemotherapy containing docetaxel, 5-fluorouracil (5FU) and a platinum salt. All patients had surgery with a D2 lymphatic dissection and R0 resection rates in 91% and 88% respectively. Median progression-free survival was 6.1 years (95% confidence intervals (CI): 1.6, NC) with median overall survival of 8.1 years (95% CI: 4.1, NC). CONCLUSION Our study suggests that an exclusive neoadjuvant approach when associated with a D2 lymph node dissection in resectable gastric and gastro-esophageal junction adenocarcinoma appears a feasible strategy with encouraging survival.

Abstract
AIM
To evaluate the feasibility of chemotherapy including fluoropyrimidine, platinum and taxane with modified dosages for unresectable gastric cancer in Japanese patients.
METHODS
We performed a feasibility study of a modified docetaxel, cisplatin and capecitabine (DCX) regimen for stage IV gastric cancer. In particular, 30 or 40 mg/m2 of docetaxel on day 1, 60 mg/m2 of cisplatin on day 1, and 2000 mg/m2 of capecitabine for 2 wk were administered every three weeks.
RESULTS
Three patients were treated with modified DCX (mDCX) with 30 mg/m2 docetaxel, and five patients were treated with this regimen with 40 mg/m2 docetaxel. Grade 3 or 4 neutropenia was observed in six of the eight patients; no patients exhibited febrile neutropenia. Partial response was achieved in four of the eight patients. Three patients underwent gastrectomy, which achieved R0 resection without residual tumors in dissected lymph nodes. In one of these three patients, resected specimens revealed pathological complete response in the primary lesion and in lymph nodes.
CONCLUSION
mDCX was well tolerated by Japanese patients with stage IV gastric cancer. This regimen might be useful for allowing gastric cancer patients with distant lymph node metastasis to undergo conversion surgery.

Abstract
Cancer remains one of the major health problems worldwide and is responsible for one in eight deaths. The worldwide research against cancer as well as genome wide association studies was successful in indentifying the loci associated with cancer but still a substantial amount of casualty remains unexplained. The reason being the cancer cell rapidly develops resistance against the chemotherapeutic or chemopreventive agent in use. Over the last decade, the thorough understanding of molecular and biochemical mechanisms of the carcinogenesis process lead to the rationale of combining anti-cancer agents (therapeutic as well as chemopreventive) to target multiple pathways. Scientists, the world over trying various combinations of chemotherapy, radiation therapy, chemopreventive agents, nanoparticles, etc., in order to specifically as well as efficiently target cancer cells. The present review article summarizes the recent advances in the combination approach against cancer in order to enhance efficacy of treatment with minimal side effects.

Abstract
Survival outcomes following multimodal treatment of operable oesophageal and gastrooesophageal cancer remain disappointingly poor. Although an appreciation of the impact of both tumour location and histological subtype is now shaping the design of clinical trials, there has been a lack of consensus of the optimal neoadjuvant treatment strategy. This update article will review recent advances in the use of both neoadjuvant chemotherapy and chemoradiotherapy. The emerging role of PET imaging to direct appropriate neoadjuvant treatment regimens and the additive benefit of biological agents are also discussed.

Abstract
PURPOSE Perioperative chemotherapy with 5-fluorouracil and cisplatin, with or without epirubicin, improves overall survival in resectable gastroesophageal junction and gastric adenocarcinoma. The aim of this retrospective multicenter study was to evaluate the safety and efficacy of perioperative chemotherapy with a FOLFOX-based regimen. PATIENTS AND METHODS We enrolled patients with resectable gastric or gastroesophageal adenocarcinoma, who had at least 3 cycles of a pre-operative FOLFOX-based regimen. The primary end point was the feasibility of the peri-operative chemotherapy. RESULTS We enrolled 109 patients from 2007 to 2012 in 12 centres. Their median age was 66, 67% were men and 73% had gastric tumours. The median number of chemotherapy courses was 6 with a median of 4 pre-operative cycles and 2 post-operative cycles. Twenty-three patients received at least 8 cycles of chemotherapy. In univariate analysis, the Karnofsky index at inclusion was the only factor associated with 8 cycles of chemotherapy. An R0 resection was achieved in 100 patients (95.2%). CONCLUSION The FOLFOX-based perioperative regimen achieves favourable results in real life practice. The optimal number of chemotherapy cycle remains to be determined. FOLFOX regimen may be used as an alternative treatment option to a cisplatin-based regimen in resectable gastroesophageal adenocarcinoma. A prospective randomized trial is needed to confirm these results.

Abstract
AIM To investigate the feasibility of preoperative docetaxel, cisplatin and capecitabine (DCC) in patients with resectable gastric cancer.
METHODS Patients with resectable gastric cancer fulfilling the inclusion criteria, were treated with 4 cycles of docetaxel (60 mg/m2), cisplatin (60 mg/m2) and capecitabine (1.875 mg/m2 orally on day 1-14, two daily doses) repeated every three weeks, followed by surgery. Primary end point was the feasibility and toxicity/safety profile of DCC, secondary endpoints were pathological complete resection rate and pathological complete response (pCR) rate.
RESULTS All of the patients (51) were assessable for the feasibility and safety of the regimen. The entire preoperative regimen was completed by 68.6% of the patients. Grade III/IV febrile neutropenia occurred in 10% of all courses. Three patients died due to treatment related toxicity (5.9%), one of them (also) because of refusing further treatment for toxicity. Of the 45 patients who were evaluable for secondary endpoints, four developed metastatic disease and 76.5% received a curative resection. In 3 patients a pCR was seen (5.9%), two patients underwent a R1 resection (3.9%).
CONCLUSION Four courses of DCC as a preoperative regimen for patients with primarily resectable gastric cancer is highly demanding. The high occurrence of febrile neutropenia is of concern. To decrease the occurrence of febrile neutropenia the prophylactic use of granulocyte colony-stimulating factor (G-CSF) should be explored. A curative resection rate of 76.5% is acceptable. The use of DCC without G-CSF support as preoperative regimen in resectable gastric cancer is debatable.

Lancet Oncol 2016; 17:1697-1708.

Abstract
BACKGROUND Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma, but has not yet been evaluated in the context of resectable patients. Here we report findings from the phase 2 part of the phase 2/3 FLOT4 trial, which compared histopathological regression in patients treated with a docetaxel-based triplet chemotherapy versus an anthracycline-based triplet chemotherapy before surgical resection. METHODS In this randomised, open-label, phase 2/3 study, eligible participants were recruited from 28 German oncology centres. Patients with resectable gastric or gastro-oesophageal junction cancer who had clinical stage cT2 or higher, nodal positive (cN+) disease, or both were randomly assigned (1:1) to either three preoperative and three postoperative 3-week cycles of intravenous epirubicin 50 mg/m2 on day 1, intravenous cisplatin 60 mg/m2 on day 1, and either fluorouracil 200 mg/m2 as continuous intravenous infusion or capecitabine 1250 mg/m2 orally (two doses of 625 mg/m2 per day) on days 1 to 21 (ECF/ECX group) or four preoperative and four postoperative 2-week cycles of docetaxel 50 mg/m2, intravenous oxaliplatin 85 mg/m2, intravenous leucovorin 200 mg/m2, and fluorouracil 2600 mg/m2 as a 24 h infusion, all on day 1 (FLOT group). Randomisation was done centrally with an interactive web-response system based on a sequence generated with blocks (block size 2) stratified by Eastern Cooperative Oncology Group performance status, location of primary tumour, age, and nodal status. No masking was done. Central assessment of pathological regression was done according to the Becker criteria. The primary endpoint was pathological complete regression (tumour regression grade TRG1a) and was analysed in the modified intention-to-treat population, defined as all patients who were randomly assigned to treatment excluding patients who had surgery but did not provide resection specimens for central evaluation. The study (including the phase 3 part) has completed enrolment, but follow-up is ongoing and this is an interim analysis. The trial is registered with ClinicalTrials.gov, number NCT01216644. FINDINGS Between Aug 18, 2010, and Aug 10, 2012, 300 patients (152 patients in the ECF/ECX group; 148 patients in the FLOT group) were enrolled into the phase 2 part of the study, 265 of whom (137 in the ECF/ECX group; 128 in the FLOT group) were assessable on a modified intention-to-treat basis. 119 (93%) of 128 patients in the FLOT group and 126 (92%) of 137 patients in the ECF/ECX group were given all planned preoperative cycles of treatment. FLOT was associated with significantly higher proportions of patients achieving pathological complete regression than was ECF/ECX (20 [16%; 95% CI 10-23] of 128 patients vs eight [6%; 3-11] of 137 patients; p=0·02). 44 (40%) of 111 patients in the ECF/ECX group and 30 (25%) of 119 patients in the FLOT group had at least one serious adverse event involving a perioperative medical or surgical complication. The most common non-surgical grade 3-4 adverse events were neutropenia (52 [38%] of 137 patients in the ECF/ECX group vs 67 [52%] of 128 patients in the FLOT group), leucopenia (28 [20%] vs 36 [28%]), nausea (23 [17%] vs 12 [9%]), infection (16 [12%] vs 15 [12%]), fatigue (19 [14%] vs 11 [9%]), and vomiting (13 [10%] vs four [3%]). INTERPRETATION Perioperative FLOT was active and feasible to administer, and might represent an option for patients with locally advanced, resectable gastric or gastro-eosophageal junction adenocarcinoma. FUNDING None.

Abstract
Docetaxel, cisplatin, and 5‐fluorouracil (DCF) significantly improved overall survival in metastatic gastroesophageal adenocarcinoma (GEA). The aim of this study was to assess efficacy of DCF regimen as perioperative chemotherapy compared with surgery alone in patients with resectable GEA. We identified 789 patients who underwent surgery alone and 62 patients who received at least one cycle of DCF regimen consisting of docetaxel (75 mg/m2 on day 1), cisplatin (75 mg/m2 on day 1), and 5‐fluorouracil (750 mg/m2/day on continuous perfusion on days 1 to 5), every 3 weeks. Overall survival was compared using Cox proportional hazards regression model with adjustments for confounding factors provided by two propensity score methods: inverse probability of treatment weighting (IPTW) and matched‐pair analysis. In Cox multivariate analysis weighted by IPTW, DCF group was associated with favorable overall survival (OS) compared with the surgery group (HR = 0.59; 95% CI, 0.45–0.78; P = 0.0003). For the matched‐pair analysis (comparing 41 patients for each group with the same baseline characteristics), median OS was 22 months and 57 months for the surgery group and DCF group, respectively (log‐rank P = 0.0011). In Cox multivariate analysis, DCF group was associated with favorable OS compared with the surgery group (HR = 0.29; 95% IC, 0.14–0.64; P = 0.0019). In the matched‐pair population, major complications (Dindo‐Clavien grade 3–5) arose in six patients (14.63%) in the DCF group and seven patients (17.07%) in the surgery group (P = 1). Perioperative DCF chemotherapy is superior to surgery alone in terms of OS. A randomized phase III trial should compare DCF to standard perioperative regimens.

Anastomotic leak predicts diminished long-term survival after resection for gastric and esophageal cancer. Surgery 2016; 160:191-203. [PMID: 27067160 DOI: 10.1016/j.surg.2016.02.020] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2015] [Revised: 01/23/2016] [Accepted: 02/18/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Previous studies have reported on the association between perioperative morbidity and diminished oncologic outcomes in patients undergoing resection for colorectal or pancreatic cancer. However, the effect of anastomotic leak (AL) on the survival of patients with gastric or esophageal cancer remains unclear. METHODS Clinicopathologic data of patients who underwent resection for gastric or esophageal cancer between 2005 and 2012 were assessed, and predictors for overall survival and disease-free survival were identified. In addition, we evaluated the impact of AL on oncologic outcomes. RESULTS Curative resection for gastric or esophageal cancer was performed in 471 patients. The primary tumor was located in the stomach and esophagus in 53% and 47% of the patients, respectively. Forty-one patients (8.7%) suffered an AL. The AL rate was significantly higher following resection for esophageal cancer compared with the resection for gastric cancer (12.9% vs 5.3%, P = .001). Postoperative mortality (4%) was not significantly associated with the occurrence of AL (4% without AL vs 7% with AL, P = .2). After a median follow-up time of 35 months, the median overall survival and disease-free survival were 101 and 93 months, respectively. Factors associated with worse overall survival in multivariate analysis included AL (P = .001), American Society of Anesthesiologists physical status (P < .0001), advanced Union for International Cancer Control (UICC) stage (P < .0001), and poorly differentiated carcinoma (G3; P = .04). In the multivariate analysis for predictors of disease-free survival, AL (P = .037), advanced UICC stage (P < .0001), poorly differentiated carcinoma (G3; P = .044), and lymphangiosis carcinomatosa (P = .004) were independently associated with a high risk for recurrence. CONCLUSION AL following resection for gastric and esophageal cancer has a negative prognostic impact on long-term survival, independent from tumor stage and biology. Further investigation of the interactions between AL and the development of tumor recurrence as well as the establishment of standardized perioperative care protocols are necessary for the improvement of outcomes after gastric and esophageal resection.

Abstract
BACKGROUND Postoperative relapse rate after gastrectomy and perioperative chemotherapy remain high in patients with advanced gastric cancer due to the spread of disseminated tumour cells in the peritoneal cavity. Perioperative administration of catumaxomab could potentially eliminate residual tumour cells after intended curative resection of the primary tumour. METHODS This open-label, phase II study investigated the safety and efficacy of catumaxomab following neoadjuvant chemotherapy and subsequent surgery in patients with resectable (T2-4, N+, M0) gastric adenocarcinoma. Patients received catumaxomab intra- (single 10 μg dose) and postoperatively (10, 20, 50 and 150 μg on days 7, 10, 13 and 16, respectively). The primary endpoint was the postoperative complication rate (maximum rate defined as <62 %) within 30 days after surgery in patients who received at least the first catumaxomab dose. RESULTS Of 64 patients treated with neoadjuvant chemotherapy, 58 underwent surgery and 54 received at least the first catumaxomab dose. Postoperative complications were reported in 18 of 54 evaluable patients (complication rate 33 %; 95 % confidence interval: 21-48 %); thus, the primary endpoint was met. The most frequent complications were pulmonary infection (17 %) and anastomosis insufficiency requiring surgery (11 %). The most common catumaxomab-related adverse events were pyrexia (67 %), leucocytosis (19 %), abdominal pain (17 %) and chills (17 %). The 4-year disease-free and overall survival rates were 38 and 50 %. CONCLUSION Intra- and postoperative administration of catumaxomab as part of a multimodal treatment approach was feasible and tolerable in patients with advanced gastric cancer and should be further investigated in a randomised trial.

Abstract
The benefit of preoperative chemotherapy in resectable gastroesophageal adenocarcinomas was not observed in signet ring cell subtype. However, the potential interest of taxane-based preoperative chemotherapy on this subtype is still an unresolved issue. Nineteen patients with localized signet ring cell adenocarcinomas received taxane-based regimens, and 17 patients underwent surgery. Complete resection was achieved in 80 %, and median overall survival was 40.8 months (95 % confidence interval (CI), 20.2—not reached). Even though one patient achieved a complete pathological response, seven patients had an upstaging of their tumors at surgery. The potential benefits of taxane-based chemotherapy seem to be limited to a reduced number of patients.

Abstract
BACKGROUND The correlation between overall survival (OS) and progression-free survival (PFS) has been evaluated in patients with metastatic or advanced gastric cancer who have received first-line and/or second-line chemotherapy. However, no corresponding analysis has been done for patients who have undergone third-line or later-line chemotherapy. METHODS A total of 303 patients from the Phase II/III studies of apatinib were pooled (the Phase II study as a training data set, the Phase III study as a testing data set). Landmark analyses of PFS at 2 months from randomization were performed to minimize lead time bias. The Cox proportional hazard model was used to test for the significance effect of PFS rate at 2 months in predicting OS. Additionally, the PFS/OS correlations were evaluated by the normal induced copula (National Institute for Health and Care Excellence) estimation model. RESULTS The median OS was 3.37 months (95% confidence interval 2.63-3.80) in patients who experienced progression at 2 months and 5.67 months in patients who did not (95% confidence interval 4.83-6.67; P<0.0001). Compared with patients who did not progress at 2 months, the adjusted hazard ratio for death was 3.39 (95% confidence interval 1.79-6.41; P<0.0001) for patients who experienced progression at 2 months. Moreover, the correlation of PFS/OS was 0.84 (95% confidence interval 0.74-0.90). Similar results were found in the testing data set. CONCLUSION These results indicate that PFS correlates strongly with OS, suggesting PFS may be a useful early endpoint for patients with advanced gastric cancer who have undergone third-line or later-line chemotherapy. These observations require prospective validation.

Abstract
BACKGROUND Neoadjuvant chemotherapy is an accepted standard of care for locally advanced esophagogastric cancer. As only a subgroup benefits, a response-based tailored treatment would be of interest. The aim of our study was the evaluation of the prognostic and predictive value of clinical response in esophagogastric adenocarcinomas. METHODS Clinical response based on a combination of endoscopy and computed tomography (CT) scan was evaluated retrospectively within a prospective database in center A and then transferred to center B. A total of 686/740 (A) and 184/210 (B) patients, staged cT3/4, cN0/1 underwent neoadjuvant chemotherapy and were then re-staged by endoscopy and CT before undergoing tumor resection. Of 184 patients, 118 (B) additionally had an interim response assessment 4-6 weeks after the start of chemotherapy. RESULTS In A, 479 patients (70%) were defined as clinical nonresponders, 207 (30%) as responders. Median survival was 38 months (nonresponders: 27 months, responders: 108 months, log-rank, p < 0.001). Clinical and histopathological response correlated significantly (p < 0.001). In multivariate analysis, clinical response was an independent prognostic factor (HR for death 1.4, 95% CI 1.0-1.8, p = 0.032). In B, 140 patients (76%) were nonresponders and 44 (24%) responded. Median survival was 33 months, (nonresponders: 27 months, responders: not reached, p = 0.003). Interim clinical response evaluation (118 patients) also had prognostic impact (p = 0.008). Interim, preoperative clinical response and histopathological response correlated strongly (p < 0.001). CONCLUSION Preoperative clinical response was an independent prognostic factor in center A, while in center B its prognostic value could only be confirmed in univariate analysis. The accordance with histopathological response was good in both centers, and interim clinical response evaluation showed comparable results to preoperative evaluation.

Abstract
BACKGROUND Perioperative chemotherapy with epirubicin, cisplatin and 5-fluorouracil (5-FU) (ECF)-like regimens is the European standard for patients with adenocarcinoma of the gastroesophageal junction (GEJ) or gastric body (GaCa) stage UICC II/III (staged according to the Union for International Cancer Control). However, limited data exist on the histopathological response and relevance of prognosis for patients homogeneously treated with ECF(-like) therapies. METHODS All patients with GEJ/GaCa treated from September 2004 to September 2008 by perioperative ECF(-like) chemotherapy were retrospectively analyzed. Cisplatin and 5-FU were substituted with oxaliplatin or capecitabine when indicated. The histopathological response was assessed using the Becker score. RESULTS Seventy-seven patients were analyzed with a median follow-up of 72.3 months. R0 resection was achieved in 53 of 68 operated patients. Recurrence was observed in 25 (32.5%) of these curatively treated patients, whereas 53/77 patients (68.8%) died, 39 (50.6%) of whom tumor related. The 5-year overall survival (OS) for the intention-to-treat population was 36.3%, and the 5-year tumor-specific survival was 42.2%. Pathological complete response (pCR) was seen in 10 patients (13.0%) and near pCR in 3 patients (3.9%). Patients with pCR had a significantly prolonged 5-year OS of 80.0 versus 29.7% compared to the nonhistopathological complete remission group (p = 0.01). CONCLUSION In our retrospective analysis, ECF(-like) pretreatment resulted in a (near) pCR rate of 16.9%. In line with other regimens, our data suggest that histopathological response predicts the OS in patients treated with ECF(-like) regimens.

Abstract
Perioperative treatment is a standard of care in locally advanced gastroesophageal cancer (GEC) (gastric adenocarcinoma and gastroesophageal junction (GEJ) adenocarcinoma). While preoperative treatment can be applied to the majority of patients, postoperative chemotherapy can be given only to a fraction. The NeoFLOT-study therefore investigates the application of prolonged neoadjuvant chemotherapy (NACT). Patients with T3, T4, and/or node-positive adenocarcinoma (GEC) were eligible for this multicenter phase II trial. NACT consisted of 6 cycles of oxaliplatin 85 mg/m(2) , leucovorin 200 mg/m(2) , 5-fluorouracil 2600 mg/m(2) and docetaxel 50 mg/m(2) (FLOT) applied q 2 wks. Application of adjuvant chemotherapy was explicitly not part of the protocol. R0-resection rate was evaluated as a primary endpoint. Of 59 enrolled patients, 50 patients underwent surgery and were assessable for the primary endpoint. R0-resection rate was 86.0% (43/50). Pathologic complete response (pCR) was 20.0% (10/50) and a further 20% (10/50) of patients achieved near complete histological remission (<10% residual tumor). Among these very good responders, 85% (17/20) had intestinal type tumors, 10% (2/20) had diffuse and 5% (1/20) had mixed type tumors. After 3 cycles of NACT, 6.9% (4/58) of patients developed progressive disease. Median disease-free survival was 32.9 months. The 1-year survival-rate was 79.3%. Grade 3-4 toxicities included neutropenia 29.3%, febrile neutropenia 1.7%, diarrhea 12.1% and mucositis 6.9%. This study indicates that intensified NACT with 6 cycles of FLOT is highly effective and tolerable in resectable GEC. Very good response (pCR and <10% residual tumor) was predominantly observed in patients with intestinal type tumors.

Abstract
Peri-operative chemotherapy has been found to benefit patients with oesophageal and gastro-oesophageal junction adenocarcinoma. This study’s aim was to evaluate the efficacy and tolerance of this treatment. The study included patients with carcinoma of the lower oesophagus and gastro-oesophageal junction in whom the disease was evaluated as potentially operable. Chemotherapy (CHT) consisted of three preoperative and three postoperative cycles of intravenous epirubicin and cisplatin on day 1 plus a continuous infusion of fluorouracil for 21 days (ECF) or oral capecitabine for 14 days (ECCap). Postoperative radio-chemotherapy (CRT) with fluorouracil or capecitabine after CHT was indicated in patients with two and more positive lymph nodes. Sixty-three patients started the treatment. Median follow-up was 32 months. Preoperative CHT was completed by 62 patients, 52 had surgery, 46 had radical resection, 25 patients had pN0 and 21 patient pN plus findings. Postoperative CHT was started in 39 (62%) patients and completed in 32 (51%). Ten (16%) patients had postoperative CRT. Adverse events of grade 3 and 4 were: neutropenia 17%, vomiting 8%, fatigue 5%, diarrhoea 3%. Reasons for omitting surgery in 11 (17%) patients were: progression in 7 patients, medically unfit in 3 patients, other in 1 patient. In the reporting period there were recurrences in 39 of all patients, in 7 locoregional only, in 10 distant plus locoregional, and in 19 distant metastases. Median survival was 24.1 months and 3-year survival rate was 42%. Peri-operative chemotherapy ECF/ECCap was feasible and well tolerated. Radical resection was performed in most patients.

Abstract
BACKGROUND The role of hepatectomy for patients with liver metastases from gastric and esophageal cancer (GELM) is not well defined. The present study examined the morbidity, mortality, and long-term survivals after liver resection for GELM. METHODS Clinicopathological data of patients who underwent hepatectomy for GELM between 1995 and 2012 at two European high-volume hepatobiliary centers were assessed, and predictors of overall survival (OS) were identified. In addition, the impact of preoperative chemotherapy for GELM on OS was evaluated. RESULTS Forty-seven patients underwent hepatectomy for GELM. The primary tumor was located in the stomach, cardia, and distal esophagus in 27, 16, and 4 cases, respectively. Twenty patients received preoperative chemotherapy before hepatectomy. After a median follow-up time of 76 months, 1-, 3-, and 5-year OS rates were 70, 37, and 24%, respectively. Postoperative morbidity and mortality rates were 32 and 4%, respectively. Outcomes were comparable between the two centers. Preoperative chemotherapy for GELM (5-year OS: 45 vs 9%, P = .005) and the lack of posthepatectomy complications (5-year OS: 34 vs 0%, P < .0001) were significantly associated with improved OS in univariate and multivariate analyses. When stratifying OS by radiologic response of GELM to preoperative chemotherapy, patients with progressive disease despite preoperative treatment had significantly worse OS (5-year OS: 0 vs 70%, P = .045). CONCLUSION For selected patients with GELM, liver resection is safe and should be regarded as a potentially curative approach. A multimodal treatment strategy including systemic therapy may provide better patient selection resulting in prolonged survival in patients with GELM undergoing hepatectomy.

Abstract
Adenocarcinoma of the stomach carries a poor prognosis and is the second most common cause of cancer death worldwide. It is recommended that surgical resection with a D1 or a modified D2 gastrectomy (with at least 15 lymph nodes removed for examination) be performed in the United States, though D2 lymphadenectomies should be performed at experienced centers. A D2 lymphadenectomy is the recommended procedure in Asia. Although surgical resection is considered the definitive treatment, rates of recurrences are high, necessitating the need for neoadjuvant or adjuvant therapy. This review article aims to outline and summarize some of the pivotal trials that have defined optimal treatment options for non-metastatic non-cardia gastric cancer. Some of the most notable trials include the INT-0116 trial, which established a benefit in concurrent chemoradiation and adjuvant chemotherapy. This was again confirmed in the ARTIST trial, especially in patients with nodal involvement. Later, the Medical Research Council Adjuvant Gastric Infusional Chemotherapy trial provided evidence for the use of perioperative chemotherapy. Targeted agents such as ramucirumab and trastuzumab are also being investigated for use in locally advanced gastric cancers after demonstrating a benefit in the metastatic setting. Given the poor response rate of this difficult disease to various treatment modalities, numerous studies are currently ongoing in an attempt to define a more effective therapy, some of which are briefly introduced in this review as well.

Abstract
BACKGROUND Perioperative chemotherapy improves the overall survival of resectable gastroesophageal adenocarcinoma (GEA) patients. However, more than 40 % of the patients are not healthy enough to complete their post-operative chemotherapy, and the progression-free survival rate is lower than 35 % at 5 years. In order to optimise neoadjuvant chemotherapy regimen, a pilot study of weekly dose-intensified cisplatin, epirubicin, and paclitaxel (PET) was conducted. The primary objective was a complete resection (R0) rate. Then, a R0 rate ≤80 % was considered as uninteresting, with an expected R0 rate of 92 %. Secondary objectives were the feasibility, safety, histological response rate (Becker score), and survival (Trial registration: NCT01830270). METHODS Patients with >T1N0M0 GEA were included. Treatment consisted of eight preoperative cycles of weekly PET regimen at 30/50/80 mg/m² of cisplatin, epirubicin, and paclitaxel, respectively. Primary prophylaxis by granulocyte colony-stimulating factor was administered. Surgery was performed 4-6 weeks following the last cycle of chemotherapy. Using Fleming two-step design with a unilateral alpha type one error of 5 % and a statistical power of 80 %, it would be required to include 68 patients. At planned interim analysis for futility, it was required to observe at least 25 of 29 patients with R0 resection to pursue inclusion. At the second step, it was required to observe at least 61 of 68 patients with R0 resection to conclude for promising activity of the dose-intensified chemotherapy. RESULTS Between May 2011 and January 2013, 29 patients were enrolled. Median age was 62 years (range 39-83 years), and seven (24 %) patients presented signet-ring cell histology. Twenty-seven (93 %) patients underwent surgery. Pathological complete responses (Becker score 1a) were observed in four patients, and nearly complete responses (Becker score 1b) for additional three patients. A R0 rate was achieved for 24 of 29 (82.7 %; 95 % CI 64-94 %) patients. No Becker score 1a/1b response was observed among patients with signet-ring cell GEA. Twenty-one (72 %) patients completed all eight cycles, and 86 % received seven or more cycles. Sixteen (56 %) patients experienced grade 3-4 neutropenia, and five patients had febrile neutropenia. Among non-haematological toxicities, mucositis and fatigue were the most frequent ones. The median-delivered relative dose intensity (DI) was 80 % for cisplatin, 75 % for epirubicin, and 79 % for paclitaxel. However, only 45 % of the patients received at least 80 % of the planned median DI for all three drugs. CONCLUSIONS Despite high R0 and pathological response rates, neoadjuvant PET chemotherapy did not meet the primary end-point and failed to show an acceptable relative DI. PET chemotherapy is not recommended in resectable GEA patients.

Abstract
UNLABELLED Three drug taxane-based regimens have shown activity in patients with metastatic or locally advanced gastric or gastro-esophageal cancer (GC/GEC). Limited tolerability of these regimens warrants treatment modification, particularly in regard of the proven equivalence of oxaliplatin and cisplatin as well as capecitabine and 5FU. Thus, a regimen with docetaxel (T), oxaliplatin (E) and capecitabine (X) was established and evaluated. METHODS Patients with metastatic or locally advanced GC/GEC, adequate organ function, ECOG PS 0-2 were enrolled. TEX regimen was administered as defined by the phase I trial with T 35 mg/m(2) and E 70 mg/m(2) on days (d) 1, 8 and X 800 mg/m(2) bid on d 1-14 every 22 days. Primary endpoint was progression free survival (PFS) rate after 6 months. RESULTS Altogether 70 patients (15 phase I; 55 phase II) were eligible for analysis. Results of the phase II part were as follows: most common grade toxicities diarrhea (30%), nausea/vomiting and infections, PFS rate after 6 months 56.3%, response rate 43%, median PFS 6.9 and overall survival 13 months, respectively. CONCLUSION The TEX regimen show similar efficacy compared to other infusional 5FU-based taxane and platinum containing triplets, but the reduced tolerability, in particular grade 3 diarrhea, limits the feasibility.
