Front Pharmacol 2024; 14:1242548. [PMID: 38259276 PMCID: PMC10800465 DOI: 10.3389/fphar.2023.1242548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 12/13/2023] [Indexed: 01/24/2024] Open
Abstract
Objective: To systematically evaluate the safety and efficacy of docetaxel plus S-1-based therapy in gastric cancer treatment. Methods: PubMed, Embase, The Cochrane Library, and Web of Science electronic databases were searched for randomized controlled trials on docetaxel plus S-1-based therapy in the treatment of gastric cancer from the establishment of the database to 1 September 2022. Relevant studies were included per pre-defined eligibility criteria, and two researchers independently screened and assessed the included literature using Review Manager v5. Outcome measures and statistics related with efficacy and safety profiles were extracted from the included studies, and Stata v15.1 was used for pooled analysis. Results: Objective response rate (odds ratio = 2.34, 95% CI = [1.32, 4.13], p = 0.003), relapse-free survival (HR = 0.68, 95% CI = [0.58, 0.79], p < 0.001), progression-free survival (HR = 0.81, 95% CI = [0.68, 0.96], p = 0.016), and overall survival (HR = 0.86, 95% CI = [0.79, 0.95], p = 0.002) of docetaxel plus S-1-based therapy (DS-based therapy) in gastric cancer treatment were better than those of the non-DS-based therapy. However, DS-based therapy was associated with increased risk of certain adverse drug effects, such as alopecia, leukopenia, and oral mucositis. Further studies are warranted to validate the efficacy superiority of DS-based versus non-DS-based regimens as per our trial sequential analysis findings. Conclusion: DS-based therapy significantly improves patients' clinical outcomes in gastric cancer, albeit at the cost of increased toxicity. Further RCTs are needed to confirm the efficacy superiority of DS-based regimens.

Abstract
The updated edition of the German, Austrian and Swiss Guidelines for Systemic Treatment of Gastric Cancer was completed in August 2023, incorporating new evidence that emerged after publication of the previous edition. It consists of a text-based "Diagnosis" part and a "Therapy" part including recommendations and treatment algorithms. The treatment part includes a comprehensive description regarding perioperative and palliative systemic therapy for gastric cancer and summarizes recommended standard of care for surgery and endoscopic resection. The guidelines are based on a literature search and evaluation by a multidisciplinary panel of experts nominated by the hematology and oncology scientific societies of the three involved countries.

Abstract
The care of patients with oesophageal cancer or of individuals who have an elevated risk of oesophageal cancer has changed dramatically. The epidemiology of squamous cell and adenocarcinoma of the oesophagus has diverged over the past several decades, with a marked increase in incidence only for oesophageal adenocarcinoma. Only in the past decade, however, have molecular features that distinguish these two forms of the disease been identified. This advance has the potential to improve screening for oesophageal cancers through the development of novel minimally invasive diagnostic technologies predicated on cancer-specific genomic or epigenetic alterations. Surgical techniques have also evolved towards less invasive approaches associated with less morbidity, without compromising oncological outcomes. With improvements in multidisciplinary care, advances in radiotherapy and new tools to detect minimal residual disease, certain patients may no longer even require surgical tumour resection. However, perhaps the most anticipated advance in the treatment of patients with oesophageal cancer is the advent of immune-checkpoint inhibitors, which harness and enhance the host immune response against cancer. In this Review, we discuss all these advances in the management of oesophageal cancer, representing only the beginning of a transformation in our quest to improve patient outcomes.

Abstract
BACKGROUND Multimodal treatment of gastric cancer includes careful preoperative staging, perioperative oncological treatment, and selective minimally invasive approach. The aim was to evaluate whether this approach improves short- and long-term outcomes in operable gastric cancer. METHODS This study included 181 gastric cancer patients who underwent curative intent surgery in Central Finland Central Hospital between years 2005 and 2021 for gastric or esophagogastric junction adenocarcinoma. Those 65 patients in group 1 operated between years 2005-2010 had open surgery with possible adjuvant therapy. During the second period including 58 patients (2011-2015), perioperative chemotherapy and minimally invasive surgery were implemented. The period, when these treatments were standard practise, was years 2016-2021 including 58 patients (group 3). Outcomes were lymph node yield, major complications and 1- and 3-year survival rates. RESULTS Median lymph node yield increased from 17 in group 1 and 20 in group 2 to 23 in group 3 (p < 0.001). Major complication rates in groups 1-3 were 12.3%, 32.8%, and 15.5% (group 1 vs. group 2, p = 0.007; group 2 vs. group 3, p = 0.018), respectively. Overall 1-year survival rates between study groups 1-3 were 78.5% vs. 69.0% vs. 90.2% (p = 0.018) and 3-year rates 44.6% vs. 44.8% vs. 68.1% (p = 0.016), respectively. For overall 3-year mortality, adjusted hazard ratio (HR) was 1.02 (95%CI 0.63-1.66) in group 2 and HR 0.37 (95%CI 0.20-0.68) in group 3 compared to group 1. CONCLUSIONS In medium-volume center, modern multimodal therapy in operable gastric cancer combined with minimally invasive surgery increased lymph node yield and improved long-term survival without increasing postoperative morbidity.

Abstract
Gastric or gastro-oesophageal junction (GEJ) adenocarcinomas present poor overall survival (OS). First-line chemotherapy regimen for patients with HER2-negative tumours is based on a doublet or triplet of fluoropyrimidine plus platinum salt ± taxane. Second-line chemotherapy (Docetaxel or Irinotecan) improves OS which nonetheless remains poor (around 5 months). The first results of immune checkpoint inhibitors (anti-PD-1) combined with chemotherapy in metastatic gastric and GEJ cancers were discordant in recent phase III trials. Data on dual-blockade (anti-PD-L1 or anti-PD-1 plus anti-CTLA-4) plus chemotherapy are lacking. DURIGAST is a randomised, multicenter, non-comparative, phase II study, evaluating safety and efficacy of FOLFIRI plus Durvalumab (anti-PD-L1) versus FOLFIRI plus Durvalumab and Tremelimumab (anti-CTLA-4) as second-line treatment of advanced gastric and GEJ adenocarcinoma. The primary objective is the rate of patients alive and without progression at 4 months. The main inclusion criteria are: patients with advanced gastric or GEJ adenocarcinoma, pre-treated with fluoropyrimidine + platinum salt ± taxane. Due to a lack of data on FOLFIRI, Durvalumab and Tremelimumab combination, a 2-step safety run-in phase has been performed before the randomised phase II. The safety run-in phase did not show any safety issue and the randomised phase II starts in September 2020.

Abstract
Purpose To determine the efficacy and toxicity of two standard chemotherapy regimens used concurrent with radiation for the treatment of esophageal cancer: cisplatin/5-fluorouracil (5-FU) and carboplatin/paclitaxel. Materials and methods We prospectively reviewed records of 364 patients with histologically confirmed stage I to IVA esophageal cancer receiving chemoradiotherapy (CRT) with or without resection. All patients received surgical evaluation and imaging at presentation as well as following completion of their course of CRT. Treatment and prognostic variables were compared across the two chemotherapy regimens. Results We identified 261 patients treated with concurrent carboplatin/paclitaxel (n = 133) or cisplatin/5-FU (n = 128). Weight loss during CRT was lower in patients receiving carboplatin/paclitaxel (median: 7.0 pounds; 4.1% body weight) vs. cisplatin/5-FU (median: 11.0 pounds; 6.5% body weight) (p < 0.01). In 117 patients receiving trimodality therapy, post-operative death rates within one month of resection were similar. Pathologic complete response was better with carboplatin/paclitaxel vs. cisplatin/5-FU, 29.6% vs. 21.8% (p = 0.03), respectively. In the multivariable analysis, there was no association between chemotherapy regimen and overall survival (OS) or progression-free survival (PFS), though there was a trend toward improved OS with carboplatin/paclitaxel with a HR = 0.75 (p = 0.08). Further analysis revealed that trimodality therapy and stage were predictors for improved OS and PFS while female gender and grade predicted for improved PFS. Conclusions Carboplatin/paclitaxel was associated with decreased weight loss and improved pathologic response for trimodality patients when compared to cisplatin/5-FU. We observed no differences in OS, PFS, or post-operative death by chemotherapy regimen for both the entire cohort and trimodality patients.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) with subsequent radical surgery has become a popular treatment modality for advanced gastric cancer (AGC) worldwide. However, the survival benefit is still controversial, and prognostic factors remain undetermined. AIM To identify clinical parameters that are associated with the survival of AGC patients after NAC and radical surgery and to establish a nomogram integrating multiple factors to predict survival. METHODS We reviewed the medical profiles of 215 AGC patients who received NAC and radical resection, and clinical parameters concerning NAC, surgery, pathological findings, and adjuvant chemotherapy were analyzed using a Cox regression model to determine their impact on survival. Based on these factors, a nomogram was developed and validated. RESULTS The overall 1-year and 3-year survival rates were 85.8% and 55.6%, respectively. Younger age (<60 years old), increased examined lymph nodes (exLNs), successful R0 resection, the achievement of pathological complete response (pCR), and acceptance of adjuvant chemotherapy were positive predictors of survival. The C-index of the established nomogram was 0.785. The area under receiver operating curve (ROC) at 1/3 years of prediction was 0.694/0.736, respectively. The model showed an ideal calibration following internal bootstrap validation. CONCLUSION A nomogram predicting survival after NAC and surgery was established. Since this nomogram exhibited satisfactory and stable predictive power, it can be inferred that this is a practical tool for predicting AGC patient survival after NAC and radical surgery.

Abstract
BACKGROUND Survival benefit of neoadjuvant chemotherapy (NAC) for advanced gastric cancer (AGC) is a debatable issue. Studies have shown that the survival benefit of NAC is dependent on the pathological response to chemotherapy drugs. For those who achieve pathological complete response (pCR), NAC significantly prolonged prolapsed-free survival and overall survival. For those with poor response, NAC yielded no survival benefit, only toxicity and increased risk for tumor progression during chemotherapy, which may hinder surgical resection. Thus, predicting pCR to NAC is of great clinical significance and can help achieve individualized treatment in AGC patients.
AIM To establish a nomogram for predicting pCR to NAC for AGC patients.
METHODS Two-hundred and eight patients diagnosed with AGC who received NAC followed by resection surgery from March 2012 to July 2019 were enrolled in this study. Their clinical data were retrospectively analyzed by logistic regression analysis to determine the possible predictors for pCR. Based on these predictors, a nomogram model was developed and internally validated using the bootstrap method.
RESULTS pCR was confirmed in 27 patients (27/208, 13.0%). Multivariate logistic regression analysis showed that higher carcinoembryonic antigen level, lymphocyte ratio, lower monocyte count and tumor differentiation grade were associated with higher pCR. Concordance statistic of the established nomogram was 0.767.
CONCLUSION A nomogram predicting pCR to NAC was established. Since this nomogram exhibited satisfactory predictive power despite utilizing easily available pretreatment parameters, it can be inferred that this nomogram is practical for the development of personalized treatment strategy for AGC patients.

ANZ J Surg 2019; 90:277-282. [PMID: 31854089 DOI: 10.1111/ans.15612] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 11/05/2019] [Accepted: 11/19/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Obesity is generally considered to be associated with worse surgical outcome and impaired oncological prognosis. The impact of pre-therapeutic body mass index (BMI) in patients with oesophagogastric cancer on the surgical outcome is controversially discussed. METHODS We retrospectively examined 730 patients who had undergone curative treatment for oesophagogastric cancer at the Medical Center of the University of Freiburg (1996-2015). Patients were divided in groups according to pre-therapeutic BMI (underweight (UW): <18.5 kg/m2 ; normal weight (NW): 18.5-25 kg/m2 ; overweight (OW): 25-30 kg/m2 ; and obese (OB): >30 kg/m2 ). RESULTS Median BMI was 24.7 kg/m2 . Forty-two patients were UW, 337 NW, 263 OW and 84 OB. No significant differences between the groups (UW/NW/OW/OB) in operating time, hospital stay, perioperative complication rate and in-hospital mortality were found. Pre-therapeutic BMI was significantly associated with 5-year survival (UW: 22%, NW: 37%, OW: 51%, OB: 50%, P < 0.001). Multivariate analysis identified UW/NW (BMI <25 kg/m2 ) as an independent risk factor for poor survival (relative risk 1.38, P = 0.001) among high American Society of Anesthesiologists score, old age, positive resection margin and high cancer stage according to the Union Internationale Contre le Cancer (UICC). CONCLUSION In oesophagogastric cancer, OW and OB patients can be treated surgically without impaired perioperative outcome and expect improved long-term survival compared to patients with a BMI <25 kg/m2 .

Abstract
Gastric cancer is a leading cause of cancer incidence and death worldwide. Patients with advanced gastric cancer benefit from a multi-modality treatment regimen. Sound oncologic resection with negative margins and complete lymphadenectomy plays a crucial role in long-term survival for patients with resectable disease. The utilization of minimally invasive techniques for gastric cancer has been slowly increasing and is proving to be both technically and oncologically safe. Perioperative chemotherapy is the current standard of care for advanced gastric cancer. A variety of chemotherapy regimens have been used with the combination of docetaxel, oxaliplatin, 5-fluorouracil, and leucovorin being the current recommendation given its superior ability to induce a complete pathologic response and prolong survival. The use of radiation has been more controversial with its optimal place in the treatment sequence being unclear. There are current ongoing studies assessing the impact of radiation as an adjunct or in place of chemotherapy. Targeted treatments (e.g., trastuzumab for human epidermal growth factor receptor 2 positive tumors and pembrolizumab for programmed death-ligand 1 positive tumors) are showing promise and are part of a continued emphasis on individualized care. Intraperitoneal chemotherapy may also play a role in preventing peritoneal recurrences for patients with high risk lesions. The treatment of patients with advanced gastric cancer in the West continues to advance and improve with a better understanding of optimal treatment sequences and the utilization of personalized treatment regimens.

Abstract
BACKGROUND To date there is no evidence that more intensive follow-up after surgery for esophagogastric adenocarcinoma translates into improved survival. This study aimed to evaluate the impact of standardized surveillance by a specialized center after resection on survival. METHODS Data of 587 patients were analyzed who underwent curative surgery for esophagogastric adenocarcinoma in our institution. Based on their postoperative surveillance, patients were assigned to either standardized follow-up (SFU) by the National Center for Tumor Diseases (SFU group) or individual follow-up by other physicians (non-SFU group). Propensity score matching (PSM) was performed to compensate for heterogeneity between groups. Groups were compared regarding clinicopathological findings, recurrence, and impact on survival before and after PSM. RESULTS Of 587 patients, 32.7% were in the SFU and 67.3% in the non-SFU group. Recurrence occurred in 39.4% of patients and 92.6% within the first 3 years; 73.6% were treated, and of those 17.1% underwent resection. In recurrent patients overall and post-recurrence survival (OS/PRS) was influenced by diagnostic tools (p < 0.05), treatment (p ≤ 0.001), and resection of recurrence (p ≤ 0.001). Standardized follow-up significantly improved OS (84.9 vs. 38.4 months, p = 0.040) in matched analysis and was an independent positive predictor of OS before and after PSM (p = 0.034/0.013, respectively). CONCLUSION After PSM, standardized follow-up by a specialized center significantly improved OS. Cross-sectional imaging and treatment of recurrence were associated with better outcome. Regular follow-up by cross-sectional imaging especially during the first 3 years should be recommended by national guidelines, since early detection might help select patients for treatment of recurrence and even resection in few designated cases.

Clinicopathological and prognostic significance of high circulating lymphocyte ratio in patients receiving neoadjuvant chemotherapy for advanced gastric cancer. Sci Rep 2018; 8:6223.

Abstract
This study was designed to investigate the prognostic value of circulating blood cell counts and subsets for patients with advanced gastric cancer (AGC) treated with neoadjuvant chemotherapy (NAC) and the factors determining pathological complete response (pCR). In 112 patients with AGC, we retrospectively examined the ratios of lymphocyte, monocyte, and neutrophil during and after NAC before surgery, and the percentages of CD3+, CD3+ CD4+, CD3+ CD8+ and CD4+/CD8+ lymphocytes as well. We also investigated their associations with the pCR rate and overall survival (OS). The ratios of lymphocyte taken before and after NAC were significantly greater in forty-four pCR cases than that in sixty-eight non-pCR cases. During NAC, the proportion of lymphocyte and the percentages of CD3+, CD3+ CD4+, and CD3+ CD8+ lymphocytes were dramatically increased in pCR group. The lymphocyte ratio showed an independent association with pCR by multivariate analysis and maintained at a relatively high level in pCR cases. By mean of 31.53% lymphocyte ratio before-NAC and 41.68% after-NAC, cases with high lymphocyte ratio showed significantly better outcome in OS. High circulating lymphocyte ratios, both before and after NAC, are positively associated with pCR and improved OS in advanced gastric cancer, which may be considered as a new prognostic biomarker.

Abstract
INTRODUCTION In advanced gastric cancer, doublet regimen including platinum salts and fluoropyrimidine is considered as a standard first-line treatment. The addition of docetaxel (75 mg/m2 q3w) to cisplatin (75 mg/m2 q3w) and 5-fluorouracil has been shown to improve efficacy. However, this regimen (DCF) was associated with frequent severe toxicities (including more complicated neutropenia), limiting its use in clinical practice. Interesting alternative docetaxel-based regimens have been developed that need to be validated. AIM GASTFOX study is a randomized phase III trial comparing FOLFOX alone or with docetaxel at 50 mg/m2 (TFOX regimen) in first-line treatment for advanced gastric cancer. In both arms, cycle is repeated every 2 weeks until disease progression or unacceptable toxicity. MATERIALS AND METHODS Main eligibility criteria: histologically proven locally advanced or metastatic gastric or esogastric junction adenocarcinoma, HER negative status, measurable disease, ECOG performance status 0 or 1, and adequate renal, hepatic and bone marrow functions. RESULTS The primary endpoint is radiological/clinical progression-free survival (PFS). A difference of 2 months for the median PFS in favor of TFOX is expected (HR = 0.73) Based on a two-sided α risk of 5% and a power of 90%, 454 events are required to show this difference. Secondary endpoints included overall survival, overall response rate, safety, quality of life and the therapeutic index. CONCLUSION This study is planned to include 506 patients to demonstrate the superiority of TFOX over FOLFOX in first-line advanced gastric cancer treatment (NCT03006432).

Abstract
Approximately half of the patients diagnosed with oesophageal cancer present with unresectable or metastatic disease. Treatment for these patients aims to control dysphagia and other cancer-related symptoms, improve quality of life and prolong survival. In the past 25 years, modestly improved outcomes have been achieved in the treatment of patients with inoperable non-metastatic cancer who are medically not fit for surgery or have unresectable, locally advanced disease. Concurrent chemoradiotherapy offers the best outcomes in these patients. In distant metastatic oesophageal cancer, several double-agent or triple-agent chemotherapy regimens have been established as first-line treatment options. In addition, long-term results of multiple large randomized phase III trials using additional targeted therapies have been published in the past few years, affecting contemporary clinical practice and future research directions. For the local treatment of malignant dysphagia, various treatment options have emerged, and self-expandable metal stent (SEMS) placement is currently the most widely applied method. Besides the continuous search for improved SEMS designs to minimize the risk of associated complications, efforts have been made to develop and evaluate the efficacy of antireflux stents and irradiation stents. This Review outlines the current evidence and ongoing trends in the different modern-day, multidisciplinary interventions for patients with unresectable or metastatic oesophageal cancer with an emphasis on key randomized trials.

Abstract
Combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) is an active but not well-tolerated regimen for advanced gastric cancer (GC) with standard 3-weekly doses. Several modified schedules (mDCFs) have been designed to reduce acute toxicities and improve feasibility as first-line therapy in patients with metastatic GC. The objective of this systematic review was to evaluate overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade (G) greater than or equal to 3 adverse event of mDCF chemotherapy in this setting. MEDLINE, SCOPUS, Embase, Web of Science, LILACS, CINAHL, Google Scholar, and the Cochrane Library were searched for studies with mDCF schedules in advanced GC. Pooled median OS, PFS, ORR (the primary endpoints), and G3 or G4 adverse events (secondary endpoints) were presented according to random effect model. Twenty-four studies were included for a total of 1311 patients, with weekly or biweekly (n=11) and reduced doses 3-weekly (n=13) schedules. The median pooled PFS and OS were 7.2 months [95% confidence interval (CI): 5.9-8.8] and 12.3 months (95% CI: 10.6-14.3), respectively. Among 23 studies with available data for ORR, the pooled result was 49% (95% CI: 43.4-54.4). The incidence of grade 3/4 neutropenia, thrombocytopenia, anemia, febrile neutropenia, stomatitis, diarrhea, nausea+vomiting, and neurotoxicity were 29.1, 5.6, 8.9, 7.6, 6.6, 4.9, and 9.9%, respectively. mDCF chemotherapy with splitted weekly or biweekly schedules, or reduced 3-weekly doses, is a very effective and well-tolerated regimen in metastatic GC. By providing a 50% ORR, such regimens may be particularly indicated for younger and fit patients for cytoreductive purposes (conversion therapy) or in case of symptomatic tumor burden.

Abstract
BACKGROUND Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. OBJECTIVES To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). SELECTION CRITERIA We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. DATA COLLECTION AND ANALYSIS Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. MAIN RESULTS We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is partly counterbalanced by increased toxicity. The benefit of epirubicin in three-drug combinations, in which cisplatin is replaced by oxaliplatin and 5-FU is replaced by capecitabine is unknown.Irinotecan extends OS slightly (by an additional 1.6 months) versus non-irinotecan-containing regimens (HR 0.87, 95% CI 0.80 to 0.95, 2135 participants, 10 studies, high-quality evidence).Docetaxel extends OS slightly (just over one month) compared to non-docetaxel-containing regimens (HR 0.86, 95% CI 0.78 to 0.95, 2001 participants, eight studies, high-quality evidence). However, due to subgroup analyses, we are uncertain whether docetaxel-containing combinations (docetaxel added to a single-agent or two-drug combination) extends OS due to moderate-quality evidence (HR 0.80, 95% CI 0.71 to 0.91, 1466 participants, four studies, moderate-quality evidence). When another chemotherapy was replaced by docetaxel, there is probably little or no difference in OS (HR 1.05; 0.87 to 1.27, 479 participants, three studies, moderate-quality evidence). We found there is probably little or no difference in OS when comparing capecitabine versus 5-FU-containing regimens (HR 0.94, 95% CI 0.79 to 1.11, 732 participants, five studies, moderate-quality evidence) .Oxaliplatin may extend (by less than one month) OS versus cisplatin-containing regimens (HR 0.81, 95% CI 0.67 to 0.98, 1105 participants, five studies, low-quality evidence). We are uncertain whether taxane-platinum combinations with (versus without) fluoropyrimidines extend OS due to very low-quality evidence (HR 0.86, 95% CI 0.71 to 1.06, 482 participants, three studies, very low-quality evidence). S-1 regimens improve OS slightly (by less than an additional month) versus 5-FU-containing regimens (HR 0.91, 95% CI 0.83 to 1.00, 1793 participants, four studies, high-quality evidence), however since S-1 is used in different doses and schedules between Asian and non-Asian population, the applicability of this finding to individual populations is uncertain. AUTHORS' CONCLUSIONS Chemotherapy improves survival (by an additional 6.7 months) in comparison to BSC, and combination chemotherapy improves survival (by an additional month) compared to single-agent 5-FU. Testing all patients for HER-2 status may help to identify patients with HER-2-positive tumours, for whom, in the absence of contraindications, trastuzumab in combination with capecitabine or 5-FU in combination with cisplatin has been shown to be beneficial. For HER-2 negative people, all different two-and three-drug combinations including irinotecan, docetaxel, oxaliplatin or oral 5-FU prodrugs are valid treatment options for advanced gastric cancer, and consideration of the side effects of each regimen is essential in the treatment decision. Irinotecan-containing combinations and docetaxel-containing combinations (in which docetaxel was added to a single-agent or two-drug (platinum/5-FUcombination) show significant survival benefits in the comparisons studied above. Furthermore, docetaxel-containing three-drug regimens have increased response rates, but the advantages of the docetaxel-containing three-drug combinations (DCF, FLO-T) are counterbalanced by increased toxicity. Additionally, oxaliplatin-containing regimens demonstrated a benefit in OS as compared to the same regimen containing cisplatin, and there is a modest survival improvement of S-1 compared to 5-FU-containing regimens.Whether the survival benefit for three-drug combinations including cisplatin, 5-FU, and epirubicin as compared to the same regimen without epirubicin is still valid when second-line therapy is routinely administered and when cisplatin is replaced by oxaliplatin and 5-FU by capecitabine is questionable. Furthermore, the magnitude of the observed survival benefits for the three-drug regimens is not large enough to be clinically meaningful as defined recently by the American Society for Clinical Oncology (Ellis 2014). In contrast to the comparisons in which a survival benefit was observed by adding a third drug to a two-drug regimen at the cost of increased toxicity, the comparison of regimens in which another chemotherapy was replaced by irinotecan was associated with a survival benefit (of borderline statistical significance), but without increased toxicity. For this reason irinotecan/5-FU-containing combinations are an attractive option for first-line treatment. Although they need to be interpreted with caution, subgroup analyses of one study suggest that elderly people have a greater benefit form oxaliplatin, as compared to cisplatin-based regimens, and that people with locally advanced disease or younger than 65 years might benefit more from a three-drug regimen including 5-FU, docetaxel, and oxaliplatin as compared to a two-drug combination of 5-FU and oxaliplatin, a hypothesis that needs further confirmation. For people with good performance status, the benefit of second-line chemotherapy has been established in several RCTs.

Abstract
BACKGROUND The optimal duration of firstline chemotherapy in metastatic esophagogastric cancer is unknown. In most clinical trials therapy was given until tumour progression or limiting toxicity. Maintenance concepts aiming to prolong the duration of response and maintain quality of life have been established in other tumour types but not in esophagogastric cancer. S-1 is an oral fluoropyrimidine with proven efficacy in metastatic esophagogastric cancer. METHODS The Maintenance Teysuno® (S-1) in esophagogastric cancer (MATEO) trial is a multinational, randomized phase II study that explores the role of S-1 maintenance therapy in Her-2 negative, advanced esophagogastric adenocarcinoma. After a 12-week firstline platinum-fluoropyrimidine-based chemotherapy patients without tumour progression are randomized in a 2:1 allocation to receive S-1 alone or continue with the same regimen as during the primary period. The primary endpoint is overall survival. Secondary endpoints include safety and toxicity, progression-free survival and quality of life. Correlative biomarker analyses focus on the identification of a subgroup of patients with a prolonged benefit from S-1 based maintenance therapy. DISCUSSION MATEO will be the first trial to define the role of a S-1 based maintenance therapy in patients having received a platinum-based firstline chemotherapy. TRIAL REGISTRATION NCT02128243 (date of registration: 29-04-2014).

Abstract
OBJECTIVES We reviewed survival outcomes and factors associated with improved outcomes for patients with stage IVB esophageal cancer who received multimodality therapy with initial chemotherapy followed by concurrent chemoradiation (CRT)±surgery. METHODS We retrospectively identified 96 patients with stage IVB esophageal carcinoma (with positive nonregional lymph nodes and/or distant organ metastasis) treated at a single institution with chemotherapy followed by concurrent CRT, with or without surgery. The Cox proportional hazard model was used to test associations between overall survival (OS), disease-free survival (DFS), locoregional relapse, distant metastasis-free survival, and potential predictive factors. RESULTS Median patient age at diagnosis was 59 years. The median OS time among all patients was 21.0 months, and 1-, 2-, and 5-year OS rates were 84.4%, 46.8%, and 17.9%, respectively; corresponding DFS time and rates were 8.1 months and 37%, 24.6%, and 24.6%, respectively. On multivariate analysis, factors that predicted improved OS with aggressive multimodal therapy included young age; lack of anorexia, fatigue at diagnosis; distant nodal metastasis without organ metastasis at diagnosis; and radiographic response to initial chemotherapy. A subset of 14 patients who had surgery after chemotherapy and concurrent CRT also had better median OS (not reached vs. 20 mo for 82 patients who did not receive surgery, P=0.001), DFS (14.6 vs. 5.9 mo, P=0.021), and distant metastasis-free survival (26.7 vs. 9.2 mo, P=0.042). CONCLUSIONS Aggressive local therapy with radiation and potentially surgery after initial palliative chemotherapy can improve prognosis for a select group of patients with stage IVB esophageal cancer.

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
The anticancer efficacy of docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy has been reported to be better than that of conventional regimens for advanced or relapsed esophageal squamous cell carcinoma (ESCC), and may become a standard therapy for this disease. Because it is extremely rare for chemotherapy to be administered as treatment for early cancer alone, the efficacy of DCF for superficial ESCC remains unknown. However, from a clinical oncological standpoint, it is important to investigate the anticancer efficacy of chemotherapy for early cancer, which may be useful for understanding the development of treatment resistance against chemotherapy in cancer. This retrospective, single-center analysis included 28 patients with superficial ESCC who received DCF for synchronous head and neck squamous cell carcinoma between June 2007 and July 2013. The response rate to DCF was 60.7%. In 14 of 17 patients who had been judged to have a complete response, local recurrence was eventually confirmed by follow-up esophagogastroduodenoscopy. The median progression-free survival for all 28 patients was 6.0 months. The anticancer efficacy of DCF was not found to be dependent on tumor progression stage or on the volume of local and metastatic tumors but on the drug sensitivity of the individual. Our results suggest that the efficacy of DCF against superficial esophageal squamous cell carcinoma appears to be limited to local lesions and metastases of regional lymph nodes, and the expected effect of DCF for early ESCC is similar to that for advanced, metastatic, or recurrent esophageal cancer.

Abstract
Background Restrictive intraoperative fluid management is increasingly recommended for patients undergoing esophagectomy. Controversy still exists about the impact of postoperative fluid management on perioperative outcome. Methods We retrospectively examined 335 patients who had undergone esophagectomy for esophageal cancer at the University Hospital Freiburg between 1996 and 2014 to investigate the relation between intra- and postoperative fluid management and postoperative morbidity after esophagectomy. Results Perioperative morbidity was 75%, the in-hospital mortality 8%. A fluid balance above average on the operation day was strongly associated with a higher rate of postoperative mortality (21% vs 3%, p < 0.001) and morbidity (83% vs 66%, p = 0.001). Univariate analysis for risk factors for adverse surgical outcome (Clavien ≥ III) identified ASA-score (p = 0.002), smoking (p = 0.036), reconstruction by colonic interposition (p = 0.036), cervical anastomosis (p = 0.017), blood transfusion (p = 0.038) and total fluid balance on the operation day and on POD 4 (p = 0.001) as risk factors. Multivariate analysis confirmed only ASA-score (p = 0.001) and total fluid balance (p = 0.001) as independent predictors of adverse surgical outcome. Conclusion Intra- and postoperative fluid overload is strongly associated with increased postoperative morbidity. Our results suggest restrictive intra- and especially postoperative fluid management to optimize the outcome after esophagectomy.

Hybrid minimally invasive esophagectomy vs. open esophagectomy: a matched case analysis in 120 patients. Langenbecks Arch Surg 2017; 402:323-331.

Abstract
PURPOSE In esophageal surgery, total minimally invasive techniques compete with hybrid and robot-assisted procedures. The benefit of the individual techniques for the patient remains vague. At our institution, the hybrid minimally invasive laparoscopic-thoracotomic esophagectomy (HMIE) has been routinely applied since 2013. We conducted this retrospective study to analyze the perioperative outcome. METHODS Since 2013, 60 patients were operated in HMIE technique for esophageal cancer. Each of these patients was paired according to the criteria of gender, BMI, age, tumor histology, pulmonary preexisting conditions, and a history of smoking with a patient treated by open esophagectomy (OE). Perioperative parameters were extracted from our prospectively maintained database and compared among the groups. RESULTS The HMIE and OE groups were homogeneous in terms of patient- and tumor-related data. There was no difference in lymph nodes harvested (22 vs. 20, p = 0.459) and R0-resection rate (95 vs. 93%, p = 0.500). The operation time for the HMIE was significantly shorter (329 vs. 407 min, p < 0.001). There was no difference between the groups with respect to surgical complications (37 vs. 37%, p = 0.575), but the patients undergoing hybrid technique showed more delayed gastric emptying (23 vs. 10%, p = 0.042). Pulmonary morbidity was significantly reduced after HMIE (20 vs. 42%, p = 0.009). This affected both the occurrence of pneumonia and pleural effusions. The difference in the overall complication rate was not significant (50 vs. 60%, p = 0.179), but life-threatening complications (Clavien/Dindo 4/5) were less frequent (2 vs. 12%, p = 0.031). Overall, there was significantly less need for transfusion after HMIE (18 vs. 50%, p < 0.001), and hospital (and IMC) stay was significantly shorter (14 (6) vs. 18 (7) days, p = 0.002 (0.003)). The multivariate analysis confirms the surgical procedure as an independent risk factor for the development of pulmonary complications (OR 3.2, p = 0.011). Furthermore, preexisting pulmonary conditions were identified as a risk factor (OR 3.6, p = 0.006). CONCLUSION Our retrospective analysis shows that reduction of postoperative pulmonary morbidity, perioperative blood loss, and shortening of hospital stay can be achieved by HMIE. The procedure is safe, and the rate of surgical complications and oncological radicality is comparable to the conventional procedure.

Lancet Oncol 2016; 17:1697-1708. [PMID: 27776843 DOI: 10.1016/s1470-2045(16)30531-9] [Citation(s) in RCA: 455] [Impact Index Per Article: 56.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 08/26/2016] [Accepted: 08/31/2016] [Indexed: 02/08/2023]
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
We analysed trends over time in palliative first-line chemotherapy in patients with locally advanced or metastatic esophagogastric cancer. Special focus was on frequency and quality of HER2-testing and trends in drug use in combination with trastuzumab. Earlier published data about patients treated outside clinical studies showed a relatively low rate of HER2-testing and insufficient test quality. A total of 2,808 patients retrospectively documented in Therapiemonitor® from 2006 to 2013 were analysed regarding treatment intensity and trends in used drugs. Data on HER2-testing and therapies were analysed in two cohorts documented in 2010 and 2011 (1) compared to 2012 and 2013 (2). Treatment intensity increased: 49.3% of patients received at least a triplet in 2013 compared to 10.1% in 2006. In cohort 2 HER2 expression was tested in 79.1% of the cases. Still, in 26.9% testing was not done as requested by guidelines. Good performance status, multiple metastases, age ≤ 65 years, the objective “to prevent progression,” good cognitive capabilities, estimated good compliance, and social integration positively influenced the probability of HER2-testing; comorbidities negatively affected it. Usage of the combination of fluoropyrimidines and cisplatin with trastuzumab declined from 67% in cohort 1 to 50% in cohort 2.

BACKGROUND The V325 study showed that docetaxel, cisplatin, and fluorouracil (DCF) prolonged overall survival (OS) of patients with advanced gastric cancer, but with a high incidence of dose-limiting toxicities. We investigated the efficacy and safety of a modified DCF (mDCF) regimen for Chinese patients with advanced gastric cancer. METHODS Untreated advanced gastric cancer patients randomly received docetaxel and cisplatin at 60 mg/m(2) (day 1) followed by fluorouracil at 600 mg/m(2)/day (days 1-5; mDCF regimen) or cisplatin at 75 mg/m(2) (day 1) followed by fluorouracil at 600 mg/m(2)/day (days 1-5; CF) every 3 weeks. The primary end point was progression-free survival (PFS). The secondary end points were OS, overall response rate (ORR), time-to-treatment failure (TTF), and safety. RESULTS In total, 243 patients were randomized to treatment (mDCF regimen 121; CF 122). Compared with CF, the mDCF regimen significantly improved PFS and OS: the median PFS was 7.2 and 4.9 months, respectively [hazard ratio (HR) 0.58, log-rank P = 0.0008], and the median OS was 10.2 and 8.5 months, respectively (HR = 0.71, P = 0.0319). Additionally, the mDCF regimen improved the parameters used as secondary objectives: the ORR was 48.7% with the mDCF regimen versus 33.9% with CF (P = 0.0244); the median TTF was 3.4 months with the mDCF regimen and 2.4 months with CF (HR = 0.67, P = 0.0027). Grade 3 and grade 4 treatment-related adverse events occurred in 77.3 % of patients who received the mDCF regimen versus 46.1% of patients who received CF (P < 0.001). CONCLUSIONS The mDCF regimen, compared with CF, significantly prolonged PFS and OS and enhanced ORR of Chinese patients with advanced gastric cancer. The mDCF regimen achieved efficacy comparable to that of DCF but with fewer toxicities, which is appropriate for the Chinese population.

Abstract
Perioperative and palliative chemotherapy for esophageal carcinoma has undergone substantial changes in recent years. The implementation of trastuzumab in the treatment of HER2-positive advanced adenocarcinoma is a milestone as it marked the introduction of the first molecularly targeted treatment of gastric cancer. Current studies are investigating whether anti-HER2-directed treatment also proves effective in the perioperative setting. Data from the CROSS study on neoadjuvant radio-/chemotherapy with paclitaxel and carboplatin have helped to establish a new standard of care for the treatment of localized esophageal cancer. Finally, preliminary experience in potentially curative treatment approaches for oligometastatic tumor stages may offer new treatment options for patients with stage IV gastric cancer. However, some of these innovative approaches urgently require validation in larger, prospective, and controlled multicenter studies. Highly active forms of radiotherapy, radio-/chemotherapy, or chemoimmunotherapy can achieve complete tumor remissions in some patients. Despite these advances, life expectancy unfortunately continues to be very limited in the majority of patients with locally advanced or metastatic esophageal carcinoma.

Abstract
Cancers of the stomach and esophagus are among the most challenging cancers of the GI tract to treat, associated with poor median survivals for metastatic disease and significant, sometimes prolonged, deteriorations in patient performance status as the diseases progress. However, in the past decade, we have begun to better understand disease biology and carcinogenesis, leading to the identification of subtypes of these diseases. There is also an increasing awareness of the global heterogeneity of disease and its impact on drug development. Our improved understanding of the molecular underpinnings of gastric and esophageal cancers has been accompanied with the development of novel therapeutic strategies. Recent actively investigated targets in this disease include human epidermal growth factor receptor 2, angiogenesis, MET, and immune checkpoint inhibition, with approvals of two new targeted agents, trastuzumab and ramucirumab. Improvements in our ability to deliver cytotoxic therapy, which is better tolerated and allows patients an opportunity to benefit from second- and more advanced lines of therapy, have also been observed. In this review, the current state-of-the-art management of advanced and metastatic gastric and esophageal adenocarcinomas, specifically highlighting the development of targeted therapies in these diseases, is described.

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 Docetaxel/cisplatin/infusional 5-fluorouracil (5-FU; DCF) is a standard chemotherapy regimen for patients with advanced gastric cancer (GC). This phase II study evaluated docetaxel/oxaliplatin (TE), docetaxel/oxaliplatin/5-FU (TEF), and docetaxel/oxaliplatin/capecitabine (TEX) in patients with advanced GC. PATIENTS AND METHODS Patients with metastatic or locally recurrent gastric adenocarcinoma (including carcinoma of the gastro-oesophageal junction) were randomly assigned (1 : 1 : 1) to TE, TEF, or TEX. Each regimen was tested at two doses before full evaluation at optimized dose levels. The primary end point was progression-free survival (PFS). Overall survival (OS), tumour response, and safety were also assessed. A therapeutic index (median PFS relative to the incidence of febrile neutropenia) was calculated for each regimen and compared with DCF (historical data). RESULTS Overall, 248 patients were randomly assigned to receive optimized dose treatment. Median PFS was longer with TEF (7.66 [95% confidence interval (CI): 6.97-9.40] months) versus TE (4.50 [3.68-5.32] months) and TEX (5.55 [4.30-6.37] months). Median OS was 14.59 (95% CI: 11.70-21.78) months for TEF versus 8.97 (7.79-10.87) months for TE and 11.30 (8.08-14.03) months for TEX. The rate of tumour response (complete or partial) was 46.6% (95% CI 35.9-57.5) for TEF versus 23.1% (14.3-34.0) for TE and 25.6% (16.6-36.4) for TEX. The frequency and type of adverse events (AEs) were similar across the three arms. Common grade 3/4 AEs were fatigue (21%), sensory neuropathy (14%), and diarrhoea (13%). Febrile neutropenia was reported in 2% (TEF), 14% (TE), and 9% (TEX) of patients. The therapeutic index was improved with TEF versus TEX, TE, or DCF. CONCLUSION These results suggest that TEF is worthy of evaluation as an arm in a phase III trial or as a backbone regimen for new targeted agents in advanced GC.

Abstract
We carried out a phase I/II trial of adding 2-weekly docetaxel to cisplatin plus fluorouracil (CF) therapy (2-weekly DCF regimen) in esophageal cancer patients to investigate its safety and antimetastatic activity. Patients received 2-weekly docetaxel (30 mg/m2 [dose level (DL)1] or 40 mg/m2 [DL2] with a 3 + 3 design in phase I, on days 1 and 15) in combination with fixed-dose CF (80 mg/m2 cisplatin, day 1; 800 mg/m2 fluorouracil, days 1–5) repeated every 4 weeks. The primary endpoint was dose-limiting toxicity (DLT) in phase I and central peer review-based response rate in phase II. At least 22 responders among 50 patients were required to satisfy the primary endpoint with a threshold of 35%. Sixty-two patients were enrolled in phase I and II. In phase I, 10 patients were enrolled with DLT of 0/3 at DL1 and 2/7 in DL2. Considering DLT and treatment compliance, the recommended phase II dose was determined as DL1. In phase II, the response rate was 62% (P < 0.0001; 95% confidence interval, 48–75%); median overall survival and progression-free survival were 11.1 and 5.8 months, respectively. Common grade 3/4 adverse events were neutropenia (25%), anemia (36%), hyponatremia (29%), anorexia (24%), and nausea (11%). No febrile neutropenia was observed. Pneumonitis caused treatment-related death in one patient. The 2-weekly DCF regimen showed promising antimetastatic activity and tolerability. A phase III study comparing this regimen with CF therapy is planned by the Japan Clinical Oncology Group. This study was registered at the UMIN Clinical Trials Registry as UMIN 000001737.

Abstract
From a global perspective, gastric cancer including adenocarcinoma of the esophagogastric junction is the fourth most common malignant tumor and the second most common cause of cancer-related death. Due to the lack of specific symptoms of early cancer, most gastric cancers are diagnosed in advanced stages. Staging should include high-resolution computed tomography of the thorax, abdomen, and pelvis and documented video-endoscopy and endoscopic ultrasound. In mucosal gastric cancer, endoscopic resection can replace surgical resection. In more advanced stages, perioperative chemotherapy has been established as a standard of care. In the metastatic setting, treatment goals are palliative. Chemotherapy can prolong survival, improve symptoms, and enhance the quality of life. Combination chemotherapy including a platinum salt plus fluoropyrimidine is the standard of care. About 16 % of gastric cancers exhibit overexpression of the growth factor receptor HER2. Trastuzumab has shown to prolong survival when combined with chemotherapy in HER2-positive gastric cancer.

Abstract
BACKGROUND We previously studied a dose-dense TCF (TCF-dd) regimen demonstrating its feasibility and an activity comparable to epirubicin-based chemotherapy and TCF q3w in terms of overall survival and time to progression (TTP). We report here the final results of a phase II study of chemotherapy with a modified TCF-dd regimen in locally advanced or metastatic gastric cancer (MGC). METHODS AND STUDY DESIGN Patients with histologically confirmed measurable MGC, not previously treated for advanced disease, received docetaxel 70 mg/m(2) day 1, cisplatin 60 mg/m(2) day 1, l-folinic acid 100 mg/m(2) days 1 and 2, followed by 5-fluorouracil (5-FU) 400 mg/m(2) bolus days 1 and 2, and then 600 mg/m(2) as a 22-h continuous infusion days 1 and 2, every 14 days, plus pegfilgrastim 6 mg on day 3. Patients aged ≥65 years received the same schedule with a dose reduction of 30 %. RESULTS Study duration: December 2007-November 2010. Forty-six consecutive patients were enrolled (78 % male, 22 % female; median age, 66 years, range, 38-76 years; ECOG PS: 0, 48 %, 1, 46 %). Primary endpoint was overall response rate (ORR). A median of four cycles (range, one to six) was administered. Forty-three patients were evaluated for response (93.5 %) and all for toxicity: 3 complete response (CR), 25 partial response (PR), 10 stable disease (SD), and 5 progressive disease (PD) were observed, for an ORR by intention to treat (ITT) of 61 % (95 % CI 47-75). Median overall survival (OS) was 17.63 months (95 % CI, 13.67-20.67); median progression-free survival was 8.9 months (95 % CI, 6.5-13.4). Twenty-one patients (46.0 %) were treated at full doses without any delay, thus respecting the dose-dense criterion. Most frequent grade 3-4 toxicities were neutropenia (20 %), leukopenia (4 %), thrombocytopenia (2 %), anemia (2 %), febrile neutropenia (6 %), asthenia (22 %), diarrhea (4 %), nausea/vomiting (11 %), and hypokalemia (6 %). Overall, TCF-dd was shown to be safe. CONCLUSIONS The TCF-dd regimen in locally advanced or MGC is confirmed to be feasible and very active and needs to be further tested in randomized studies.

Biweekly docetaxel, fluorouracil, leucovorin, oxaliplatin (TEF) as first-line treatment for advanced gastric cancer and adenocarcinoma of the gastroesophageal junction: safety and efficacy in a multicenter cohort. Gastric Cancer 2014; 17:341-7.

Abstract
BACKGROUND Docetaxel-cisplatin-5-FU chemotherapy is superior to 5-FU-cisplatin in terms of response rate and survival in advanced gastric cancer (AGC), but is more toxic. Oxaliplatin is better tolerated than cisplatin, which it can effectively replace in this setting. We hypothesize that incorporating docetaxel into a simplified FOLFOX regimen should be a tolerable and effective option in first-line treatment of AGC. METHODS Data were collected at six French centers from patients with metastatic or local AGC who received docetaxel, fluorouracil, leucovorin, or oxaliplatin (TEF) as first-line treatment. TEF was administered as follows: docetaxel (50 mg/m(2)), oxaliplatin (85 mg/m(2)), and leucovorin (40 mg/m(2)) on day 1, and 5-FU continuous infusion for 48 h (2400 mg/m(2)) every 2 weeks. RESULTS Forty-one patients were enrolled. Performance status was grade 0 and 1 in respectively 27 and 58 % of patients; 17 patients had adenocarcinoma of the gastroesophageal junction; 37 patients had metastatic disease, 22 had a poorly differentiated or diffuse type. Objective response rate was 66 %, with a complete response in two patients (5 %). Median progression-free survival and overall survival were respectively 6.3 and 12.1 months. Tolerability was acceptable with no treatment-related deaths. The most frequent grade 3-4 toxicities were neutropenia (30 %) and neuropathy (12.5 %). Curative intent surgery after response to TEF was performed in seven patients (17 %). CONCLUSION TEF is an effective first-line treatment with an acceptable toxicity profile for patients with AGC. It may allow curative resection in initially unresectable patients. TEF should now be evaluated in prospective randomized trials.

Abstract
The optimal medical treatment for advanced gastric cancer is currently the source of debate. Cytotoxic treatment has been shown to prolong survival and provide improved symptom control compared with best supportive care alone, but a global standard has not yet been defined. A literature research was undertaken. Results were evaluated by an international author team. The conclusions of this are presented in this paper. Combination chemotherapy with cisplatin and 5-fluorouracil was the preferred first-line chemotherapy, but oxaliplatin has shown equivalent efficacy to cisplatin. Oral fluoropyrimidines, especially S-1 and capecitabine, can substitute for 5-fluorouracil. Modern doublet regimens are preferred in the majority of patients on the basis of a balanced benefit-to-risk ratio. In selected fit and compliant patients, especially those with a high tumor burden or potential secondary resectability, a third drug may be added because triplet chemotherapy led to higher responses rates and enhanced efficacy. However, docetaxel also adds a significant increase in side effects. Monotherapy and early dose modifications should be considered in elderly and infirm patients. Beyond that, our understanding of gastric cancer tumor biology is increasing. In HER2-positive gastric cancer, the addition of the monoclononal anti-HER2 antibody trastuzumab to cisplatin and fluoropyrimidines has prolonged survival duration. Second-line chemotherapy with single agents has now become a proven treatment option. Alternatively, anti-angiogenic treatment with ramucirumab is on the horizon. In conclusion, combination chemotherapy is regarded as the global standard of care for the first-line treatment of advanced gastric cancer. Molecularly targeted treatments are being explored, preferably in combination with a backbone of chemotherapy doublets.

Addition of docetaxel to S-1 without platinum prolongs survival of patients with advanced gastric cancer: a randomized study (START). J Cancer Res Clin Oncol 2013; 140:319-28. [PMID: 24366758 PMCID: PMC3895196 DOI: 10.1007/s00432-013-1563-5] [Citation(s) in RCA: 134] [Impact Index Per Article: 12.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2013] [Accepted: 11/28/2013] [Indexed: 12/12/2022]
Abstract
Purpose
Cisplatin plus 5-fluorouracil has been globally accepted as a standard regimen for the treatment for advanced gastric cancer. However, cisplatin has several disadvantages, including renal toxicity and the need for admission. S-1 plus cisplatin has become a standard treatment for advanced gastric cancer in East Asia. This phase III study was designed to evaluate the potential benefits of adding docetaxel to S-1 without a platinum compound in patients with advanced gastric cancer. Methods Patients were randomly assigned to receive docetaxel plus S-1 or S-1 alone. The docetaxel plus S-1 group received docetaxel on day 1 and oral S-1 on days 1–14 of a 21-day cycle. The S-1 alone group received oral S-1 on days 1–28 of a 42-day cycle. The primary end point was overall survival. Results Of the 639 patients enrolled, 635 were eligible for analysis. The median overall survival was 12.5 months in the docetaxel plus S-1 group and 10.8 months in the S-1 alone group (p = 0.032). The median progression-free survival was 5.3 months in the docetaxel plus S-1 group and 4.2 months in the S-1 alone group (p = 0.001). As for adverse events, neutropenia was more frequent in the docetaxel plus S-1 group, but remained manageable. Conclusion As first-line treatment for advanced gastric cancer, docetaxel plus S-1 significantly improves median overall and progression-free survival as compared with S-1 alone.

J Transl Med 2013; 11:204. [PMID: 24004449 PMCID: PMC3766246 DOI: 10.1186/1479-5876-11-204] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2013] [Accepted: 09/02/2013] [Indexed: 12/29/2022] Open
Abstract
Background Forkhead box transcription factor 1 (FOXM1) has been reported to overexpress and correlate with pathogenesis in a variety of human malignancies. However, little research has been done to investigate its clinical significance in gastric cancer. Methods We examined the expression of FOXM1 in 103 postoperational gastric cancer tissues and 5 gastric cell lines by immunohistochemistry and western blot analysis respectively. Data on clinic-pathological features and relevant prognostic factors in these patients were then analyzed. Moreover, the association of FOXM1 expression and chemosensitivity to docetaxel in gastric cancer cells was further explored. Results Our study demonstrated that the level of FOXM1 expression was significantly higher in gastric cancer than in para-cancer tissues (P < 0.001) and normal gastric cell lines (P = 0.026). No significant association was found between FOXM1 expression and any clinical pathological features (P > 0.1). FOXM1 amplification was identified as an independent prognostic factor in gastric cancer (P = 0.001), and its affection is more significant in patients with tumor size larger than 5 cm (P = 0.004), pT3-4 (P = 0.003) or pIII-IV (P = 0.001). Additionally, shown to mediate docetaxel resistance in gastric cancers by our research, FOXM1 was revealed to alter microtubule dynamics in response to the treatment of docetaxel, and the drug resistance could be reversed with FOXM1 inhibitor thiostrepton treatment. Conclusions FOXM1 can be a useful marker for predicting patients’ prognosis and monitoring docetaxel response, and might be a new therapeutic target in docetaxel resistant gastric cancer.

Abstract
The addition of docetaxel to cisplatin and 5-fluorouracil was shown to confer a survival benefit in patients with advanced gastric cancer (one; AGC), although with increased toxicity. We hereby report our experience with the use of docetaxel, cisplatin, and 5-fluorouracil (DCF). Data on all consecutive patients who received first-line treatment with DCF at our institute were analyzed retrospectively. Twenty-three patients were included. The median age was 63 years. Patients received an average of 10 cycles (range, 1-24). All experienced grade ≥3 toxicity, requiring hospitalization in 35%. There was one toxic death. The median progression-free and overall survival rates were 10.0 and 12.8 months, respectively; the 2-year and 3-year survival rates were 22 and 17%, respectively. The DCF regimen is indeed associated with substantial toxicity, although manageable. Nevertheless, the observed benefit was remarkable compared with any previous report on chemotherapy in AGC, and should therefore represent a valid treatment option in AGC and a platform for future combinations.
