Treatment with Ramucirumab-paclitaxel in a metastatic gastric cancer patient undergoing hemodialysis: A case report

Rationale:Ramucirumab, a human Ig 1 monoclonal antibody against vascular endothelial growth factor receptor-2, in combination with paclitaxel is a second-line chemotherapy for patients with metastatic gastric cancer. Several reports have suggested that dose adjustments of cetuximab, an anti- epidermal growth factor receptor antibody, are not required in patients with renal impairment. However, the combination chemotherapy of ramucirumab and cytotoxic drug for hemodialysis (HD) patients has not been reported.Patient concerns:A 65-year-old man on HD was diagnosed with gastric cancer and underwent a subtotal gastrectomy with D2 lymphadenectomy. Abdominal computed tomography (CT) was examined after completion of 8 cycles of adjuvant chemotherapy with capecitabine combination oxaliplatin.Diagnosis:The patient was diagnosed with advanced gastric cancer at stage IIIb (pT3N2M0) 11 months ago. Unfortunately, 9 months after the start of adjuvant chemotherapy, multiple liver metastases from gastric cancer were found by abdominal CT.Interventions:He began receiving weekly paclitaxel(80 mg/m²) and every 15-day ramucirumab (8 mg/kg). HD was performed next day after administration of chemotherapy and repeated 3 times a week.Outcomes:He was treated with ramucirumab without dose adjustment. The metastatic liver mass had a partial response, after 2 and 4 cycles of chemotherapy and had a stable disease up to 12 cycles of chemotherapy. No obvious adverse effect was observed during treatment. However, after 14 cycles chemotherapy, follow-up abdominal CT revealed progression disease of multiple liver metastasis and lymph nodes invasion.Lessons:The paclitaxel chemotherapy with ramucirumab is effective and safe in HD patients with metastatic gastric cancer. As seen in patients with normal kidney function, ramucirumab can be safely administered without a dose reduction.     

SOCRATE-PRODIGE 55 trial: A randomized phase II study to evaluate second-line ramucirumab alone or with paclitaxel in older patients with advanced gastric cancer

IntroductionPatients ≥ 70 years old constitute 40% of patients with advanced gastric cancer (GC). Ramucirumab plus Paclitaxel is a therapeutic option validated in the second-line treatment of advanced GC, but as older patients are at higher risk of severe toxicity, due to comorbidities and/or frailty, we aimed to evaluate second-line Ramucirumab alone or combined with Paclitaxel in terms of overall survival (OS) and quality of life (QoL) in patients ≥ 70 years-old with advanced GC.MethodsIn this multicenter, randomized, open-label, non-comparative, prospective phase II clinical trial, the main inclusion criteria are: patients ≥ 70 years old, with advanced GC having progressed after first-line chemotherapy or in the six months following the last administration of adjuvant chemotherapy, with WHO performance status <2. They are randomized to receive either ramucirumab alone (arm A) or ramucirumab plus Paclitaxel (arm B). The primary endpoint is 6-month OS and QoL evaluated with the EORTC QLQ-ELD14 questionnaire. The secondary endpoints include other parameters of QoL, time to definitive deterioration (TTDD) in QoL and TTDD in autonomy, treatment toxicities, other parameters of survival and disease control, identification of geriatric and nutritional prognostic scores and predictive factors of treatment safety and efficacy. OS of 60% is expected at 6 months (H0:40%). Using a Simon-minimax design, with one-sided α risk of 2% and 80% power for OS, and considering 5% lost to follow-up, it is necessary to randomize 56 patients in each arm.PerspectivesAs older patients are at higher risk of chemotherapy toxicity, ramucirumab alone could be an interesting alternative to Paclitaxel plus ramucirumab, as a second-line therapy for patients ≥ 70 years old with advanced GC, and needs to be evaluated.     

Advanced gastric cancer:Current treatment landscape and future perspectives

Gastric cancer currently ranks fourth in cancer-related mortality worldwide. In the western world, it is most often diagnosed at an advanced stage, after becoming metastatic at distant sites. Patients with advanced disease(locally advanced or metastatic) have a somber prognosis, with a median overall survival of 10-12 mo, and palliative chemotherapy is the mainstay of treatment. In recent years, novel approaches using inhibition of human epidermal growth factor receptor 2(HER2) have demonstrated significant improvements in progression-free and overall survival, compared with chemotherapy alone, in first-line treatment of patients with overexpression of HER2. In addition, both second-line chemotherapy and treatment with the vascular endothelial growth factor receptor-inhibitor ramucirumab demonstrated significant benefits in terms of overall survival, compared with best supportive care, in randomized studies. Moreover, ramucirumab in combination with chemotherapy demonstrated further significant benefits in terms of progression-free and overall survival, compared with chemotherapy alone, in second-line treatment for patients with metastatic gastric cancer. A recently published molecular classification of gastric cancer is expected to improve patient stratification and selection for clinical trials and provide a roadmap for future drug development. Nevertheless, despite these developments the prognosis of patients with advanced gastric cancer remains poor. In this review we discuss current standards of care and outline major topics of drug development in gastric cancer.     

Molecular targeting to treat gastric cancer

Trastuzumab that targets human epidermal growth factor receptor 2 (HER2) protein is the only approved molecular targeting agent for treating gastric cancer in Japan and the outcomes have been favorable. However, trastuzumab is effective for only 10% to 20% of the population with gastric cancer that expresses HER2 protein. Molecular targeting therapy with bevacizumab against vascular endothelial growth factors (VEGF) and with cetuximab and panitumumab against the epidermal growth factors pathway that have been approved for treating colorectal cancer are not considered effective for treating gastric cancer according to several clinical trials. However, ramucirumab that targets VEGF receptor-2 prolonged overall survival in a large phase III clinical trial and it might be an effective molecular targeting therapy for gastric cancer. The significance of molecular targeting therapy for gastric cancer remains controversial. A large-scale randomized clinical trial of novel molecular targeting agents with which to treat gastric cancer is needed.     

Targeted therapies in gastric cancer and future perspectives

Advanced gastric cancer(AGC) is associated with a high mortality rate and, despite multiple new chemotherapy options, the survival rates of patients with AGC remains poor. After the discovery of targeted therapies, research has focused on the new treatment options for AGC. In the last two decades, many targeted molecules were developed against AGC. Currently, two targeted therapy molecules have been approved for patients with AGC. In 2010, trastuzumab was the first molecule shown to improve survival in patients with HER2-positive AGC as part of a first-line combination regimen. In 2014, ramucirumab was the second targeted molecule to improve survival rates and was suggested as treatment for patients with AGC who had progressed after firstline platinum plus fluoropyrimidine with or without anthracycline chemotherapy. Ramucirumab was the first targeted therapy acting as a single agent in patients with advanced gastroesophageal cancers. Although these two molecules were introduced into clinical use, many other promising molecules have been tested in phase Ⅰ-Ⅱ trials. It is obvious that in the near future many different targeted therapies will be in use for treatment of AGC. In this review, the current status of targeted therapies in the treatment of AGC and gastroesophageal junction tumors, including HER(2-3) inhibitors, epidermal growth factor receptor inhibitors, tyrosine kinase inhibitors, antiangiogenic agents, c-MET inhibitors, mammalian target of rapamycin inhibitors, agents against other molecular pathways fibroblast growth factor, Claudins, insulin-like growth factor, heat shock proteins, and immunotherapy, will be discussed.     

Recent advances and future trends in the targeted therapy of metastatic gastric cancer

The better understanding of the molecular mechanisms behind gastric cancer has led to the development of new therapeutic strategies that are likely to improve patient outcomes in the near future. Recently, targeting the HER2 and the VEGF pathways with trastuzumab and ramucirumab, respectively, have been found to improve survival, while directed therapies against a number of other pathways are under clinical evaluation. These include the hepatocyte growth factor and its receptor c-MET, the insulin-like growth factor 1, the fibroblast growth factor, the mammalian target of rapamycin (mTOR), the epidermal growth factor receptor, and other pathways, as well as relevant immunotherapeutic strategies. This article reviews recent advances and future trends of these concepts for gastric cancer and adenocarcinoma of the gastroesophageal junction.     

Second-line treatment of advanced hepatocellular carcinoma: Time for more individualized treatment options?

Hepatocellular carcinoma (HCC) is the most frequently diagnosed primary tumor of the liver and is usually detected as advanced disease. It is an aggressive disease that often progresses rapidly when it fails to respond to treatment. As such, patients have limited opportunities to try different subsequent-line treatment regimens. In the last 5 years, the number of agents and/or regimens available for the treatment of advanced HCC has significantly increased, which has made treatment choices for this patient population increasingly complex. In the second-line setting, several phase III trials of regorafenib (RESORCE), ramucirumab (REACH/REACH-2), and cabozantinib (CELESTIAL) have demonstrated clinically meaningful survival benefits in patients with the disease. However, the median overall survival of patients with advanced HCC remains unchanged at approximately 12 mo from the start of systemic second-line therapy, with a limited duration of response. Evidence from the REACH/REACH-2 trials demonstrated for the first time that baseline alpha-fetoprotein (AFP) levels can be used as an identification factor to select those who are likely to benefit the most from ramucirumab treatment. Ramucirumab is both well tolerated and efficacious and has a clinically acceptable safety profile. Therefore, it should be considered an option for patients with AFP levels ≥ 400 ng/mL.     

Second-line treatment of metastatic gastric cancer:Current options and future directions

Gastric cancer remains one among the leading causes of cancer-related deaths, regardless of its decreasing incidence and newly available treatment options. Most patients present at an advanced stage and are treated with upfront systemic chemotherapy. Those patients receiving first-line therapy may initially respond to treatment, but many of them relapse over time. In such condition, second-line treatment for disease progression remains the only available option. Although there exists no standard approach in the second-line setting, several phase Ⅲ trials have shown modest survival benefit in patients receiving irinotecan, taxane and ramucirumab over the best supportive care or active agents. This review analyzes the currently available treatment regimens and future directions of research in the second-line setting for metastatic gastric cancer with the best available evidence. Additionally, the prognostic factors that influence patient survival in those receiving second-line therapy are discussed.     

Current and emerging therapies in unresectable and recurrent gastric cancer

Gastric cancer is one of the most lethal cancers worldwide despite many advances and options in therapy. As it is often diagnosed at an advanced stage, prognosis is poor with a median overall survival of less than twelve months. Chemotherapy remains the mainstay of treatment for these patients but it confers only a moderate survival advantage. There remains a need for new targeted treatment options and a way to better define patient populations who will benefit from these agents. In the past few years, there has been a better understanding of the biology, molecular profiling, and heterogeneity of gastric cancer. Our increased knowledge has led to the identification of gastric cancer subtypes and to the development of new targeted therapeutic agents. There are now two new targeted agents, trastuzumab and ramucirumab, that have recently been approved for the treatment of advanced and metastatic gastric cancer. There are also many other actively investigated targets, including epidermal growth factor receptor, the phosphatadylinositol 3-kinase/protein kinase B/mammalian target of rapamycin pathway, c-Met, poly ADP-ribose polymerase, and immune checkpoint inhibition. In this review, we discuss the current management of advanced gastric cancer as well as emerging targeted therapies and immunotherapy.     

Medical management of gastric cancer: A 2014 update

Gastric cancer represents a serious health problem on a global scale. It is the second leading cause of cancer-related death worldwide. Novel therapeutic targets are desperately needed because the meager improvement in the cure rate of about 10% realized by adjunctive treatments to surgery is unacceptable as > 50% patients with localized gastric cancer succumb to their disease. Either postoperative chemoradiotherapy (United States), pre-and post-operative chemotherapy (Europe), and adjuvant chemotherapy after a D2 resection (Asia) can all be regarded as standards of care in the localized gastric cancer management. In metastatic disease the addition of trastuzumab to chemotherapy is standard of care in Her2 positive disease. In the HER2 negative population, the treatments remain limited. In the first line setting, the standard of care is a combination of fluoropyrimidine and platinum containing chemotherapy, with or without epirubicin or docetaxel. The results of targeted therapy trials have by and large been disappointing, but none of these trials looked at an appropriately enriched population. Finally there is a meager overall survival benefit in treating patients with metastatic disease in the second line setting, with either irinotecan, docetaxel or ramucirumab however none of these drugs have been compared head to head in a well-powered randomized controlled trial.     

胃癌化疗前后循环血浆VEGF、IL-8变化的临床意义

目的探讨VEGF、IL-8在胃癌患者化疗前后血浆中表达的临床意义。方法采用酶联免疫吸附法（ELISA）分别检测45例胃癌患者化疗前后血浆VEGF、IL-8水平，10名正常健康志愿者血浆作为对照。结果恶性肿瘤组化疗前血浆VEGF、IL-8含量明显高于对照组（P〈0．001），与TNM分期有关，但与肿瘤组织分化类型无明显相关性。化疗后血浆VEGF、IL-8显著下降（P〈0.001）。结论VEGF、IL-8是肿瘤发展和转移的有效生物学指标。化疗后VEGF、IL-8的表达量可能有助于临床判断化疗近期疗效。

Ramucirumab-related Oral Pyogenic Granuloma: A Report of Two Cases

Pyogenic granuloma (PG) is a granulomatous elevated lesion that occurs on the skin and mucous membranes. We herein report two cases of intra-oral PG that developed during the administration of ramucirumab for gastric cancer. Case 1 involved a 55-year-old man with a 6-mm tumor on the right tongue, and case 2 involved a 67-year-old man with a 5-mm tumor on the upper lip. The imbalance in angiogenesis caused by ramucirumab and the deterioration in the local oral environment were suggested to have caused the PG. Medical and dental collaboration is essential during the administration of ramucirumab.     

Third-line chemotherapy with paclitaxel, irinotecan hydrochloride and cisplatin for recurrent gastric cancer: a case report

With the availability of new chemotherapeutic agents such as S-1 and paclitaxel (TXL) for advanced gastric cancer, the development of a strategy for a third-line chemotherapy is urgently needed. We treated a patient with recurrent gastric cancer using TXL, irinotecan hydrochloride (CPT-11) and cisplatin (CDDP) as a third-line chemotherapy. The patient was a 46-year-old man who had undergone total gastrectomy for advanced gastric cancer with lymph node metastases. For postoperative recurrence, he was first treated with S-1 as an outpatient; however, tumor markers increased, and para-aortic lymph node metastasis was revealed by thoracic and abdominal CT scan. A second-line therapy with weekly TXL and CDDP was then added, but resulted in PD. Therefore, combination chemotherapy with TXL, CPT-11 and CDDP was started biweekly as a third-line chemotherapy. TXL (80mg/m2) was infused over 1 hour after short premedication, followed by CPT-11 (25mg/m2) and CDDP (15mg/m2) over 30 min. After 6 courses of this therapy, the serum AFP and TPA returned to normal, and the size of the metastatic para-aortic lymph nodes reduced. The effect of this therapy was judged as PR and the toxicity of this regimen was tolerable. The patient has undergone 10 courses of this therapy and is maintaining a clinical PR. The patient was able to resume his full social activities. TXL, CPT-11 and CDDP combination chemotherapy may be useful and safe for patients with recurrent gastric cancer, even after first-or second-line therapy with S-1 or taxanes.     

The role of ramucirumab with docetaxel in epidermal growth factor receptor mutant and wild-type non-small cell lung cancer

BackgroundRamucirumab paired with docetaxel extends progression free survival and overall survival in non-small cell lung cancer (NSCLC) following progression on platinum therapy. There is some data that epidermal growth factor receptor (EGFR) mutant disease would respond better to vascular endothelial growth factor receptor (VEGFR) therapy than EGFR wild type disease.MethodsThis retrospective, single-institution cohort study reports outcomes of patients who received docetaxel with or without ramucirumab according to EGFR status. Clinical data including age, performance status, metastatic burden and prior treatment history was obtained and reported with time on treatment and overall survival as primary endpoints. Data analysis was performed for three cohorts: EGFR mutant disease receiving docetaxel and ramucirumab (EGFR-doce/ram), EGFR mutant disease receiving docetaxel alone (EGFR-doce) and EGFR wild type disease receiving docetaxel and ramucirumab (WT-doce/ram).ResultsPatients in the EGFR-doce/ram cohort had a median time on docetaxel of 1.4 months (95% CI: 0.72–5.2 months) and of 0.8 months (95% CI: 0.2–6.5 months) on ramucirumab. Patients in the EGFR-doce cohort were on docetaxel for a median 1.4 months (95% CI: 0.9–2.4 months). Patients in the WT-doce/ram cohort had a median time on docetaxel of 2.3 months (95% CI: 1.6–4.1 months) and on ramucirumab of 1.4 months (95% CI: 0.8–3.2 months). There was no significant difference between time on ramucirumab or docetaxel between the cohorts. Overall survival for the three cohorts was noted to be 6.7 months (95% CI: 2.5–16.2 months) for the EGFR-doce/ram cohort, 4.9 months (95% CI: 4.2–12.5 months) for the EGFR-doce cohort and 6.6 months (95% CI: 4.3–12.8 months) for the WT-doce/ram cohort. There was no significant difference in overall survival between the cohorts.ConclusionsOur data did not support the initial hypothesis that patients with EGFR mutant disease would do better with the addition of ramucirumab. Our study was limited by small sample size, retrospective nature and inability to control for confounders including prior bevacizumab or immune checkpoint inhibitor (ICI) exposure. This study offers real-world estimates to clinicians and patients about the length of time they can expect to derive benefit from the combination of ramucirumab and docetaxel.     

Expression and clinical significance of SYNE1 and MAGI2 gene promoter methylation in gastric cancer

Gastric cancer is the fifth most common cancer and the third leading cause of cancer-related mortality globally. Abnormal DNA methylation is closely related to gastric cancer. The purpose of the study was to investigate the methylation of the SYNE1 and MAGI2 gene promoter and its relationship with the clinical-pathological factors, chemotherapy efficacy, and survival, thus providing a new biomarker for the prognosis and chemotherapy efficacy in gastric cancer.The methylation status of SYNE1 and MAGI2 in gastric cancer and adjacent tissues was detected by MSP method in 70 cases of advanced gastric cancer paraffin specimens.The methylation rate of the SYNE1 and MAGI2 gene promoter region was higher in gastric cancer tissues compared with adjacent tissues. The methylation status of SYNE1 was associated with the age at diagnosis and the size of the primary tumors, but no clinical or pathological factors have been found to be related with the methylation status of MAGI2 promoter. A high level of SYNE1 promoter methylation was associated with poorer chemotherapy efficacy in recurrent patients with gastric cancer. Thirty-three percent of the 70 patients exhibited highly methylated MAGI2; in this group, the median progression-free survival time was 4.1 months, shorter than those with negative methylated MAGI2 whose PFS was 5.1 months.MAGI2 is more methylated in gastric cancer than in adjacent tissues suggesting that hypermethylation changes in MAGI2 may be one of the mechanisms of tumorigenesis in gastric cancer. The methylation status of the SYNE1 and MAGI2 promoter regions may affect the chemotherapy efficacy of advanced gastric cancer. The prognosis of MAGI2-negative patients was better than that of positive ones, suggesting that MAGI2 may be an independent prognostic factor for PFS in patients with advanced gastric cancer.     

A long-time survivor of alpha-fetoprotein-producing gastric cancer successfully treated by fluoropyrimidine-based chemotherapy: a case study

A 67-year-old male with advanced gastric cancer and lymph node metastasis as well as a tumor embolus in the portal vein was treated by S-1/cisplatin therapy. The serum alpha-fetoprotein levels were elevated to 836 ng/ml at the first visit. After one course of chemotherapy, the patient showed stable disease; the serum level of alpha-fetoprotein also decreased to 626 ng/ml after a transient increase, and therefore reduction surgery was performed. A total gastrectomy with a distal pancreatectomy, splenectomy, and regional lymph node dissection was performed. The resected specimen was diagnosed to be alpha-fetoprotein-producing gastric cancer. There were no metastatic foci in the resected lymph nodes, presumably due to the preoperative chemotherapy. S-1/cisplatin therapy was continued after the operation to treat the remaining tumor embolus in the portal vein. After one course of this therapy, the tumor embolus disappeared. However, a lymph node measuring 1.5 cm in diameter appeared in the hepatoduodenal ligament. Therefore, the chemotherapy was changed to paclitaxel monotherapy. After 2 courses of paclitaxel monotherapy, the lymph node swelled, and thus 5′-deoxy-5-fluorouridine was added to the paclitaxel regimen. After 5 courses of this regimen, the lymph node swelling disappeared without any other new lesions and a total of 21 courses were performed. The patient remained stable for over 8 years without recurrence. The expression of chemoresistance-related proteins was retrospectively analyzed by immunohistochemistry to evaluate the chemoresistance. The ortate phosphoribosyltransferase expression was strongly positive, and the good outcome in this case may have been associated with this result.     

Microvessel density is a prognostic marker of human gastric cancer

INTRODUCTIONGastric cancer is one of the most frequent and lethal malignancies worldwide, especially in Eastern Asia including China, and the 5-year survival rate is only about 20%[1]. A recent research has shown an increasing trend of gastric cancer mortality in China in the past 20 years, especially in rural areas and among aged people[2]. To date, the treatment outcome of this common malignancy is still not satisfactory. One major difficulty in the diagnosis and treatment of gastric c…     

Effectiveness of preoperative chemotherapy for far advanced gastric cancer

We herein report a case in which preoperative chemotherapy with cisplatin and 5-fluorouracil was found to effectively treat far advanced gastric cancer invading the pancreas forming a huge mass with regional and distant lymph node metastases. As a result of this treatment regimen, a potentially curative resection was performed which led to a substantially increased survival. The patient was treated with 10 mg of cisplatin and 1000 mg of 5-fluouracil each day preoperatively. After the continuous administration of these drugs for 28 days, the findings of extensive pancreas invasion and lymph node metastases dramatically disappeared. The tumor could be curatively resected by a total gastrectomy with lymph nodes dissection, combined with a distal pancreatectomy and splenectomy. A histological study of a resected specimen showed some cancer cell infiltration remaining within the muscularis propria with fibrous change. There was no evidence of either pancreas invasion or lymph node metastasis. As a result, postoperative adjuvant chemotherapy was performed, 14 months later lymph nodes recurrence was detected and the patient died 20 months after surgery. Our findings suggest that preoperative chemotherapy may thus be effective for the treatment of gastric cancer by both reducing the tumor burden and prolonging survival.     

The successfully curative treatment of advanced gastric adenocarcinoma with multiple liver metastases and paraaortic lymph node metastases by salvage operation following the biweekly paclitaxel and S-1 combination chemotherapy: a case report

We report the case of 67-year-old man who was given a diagnosis of advanced gastric adenocarcinoma. Complete response of multiple liver and paraaortic lymph node metastases occurred in this patient after combination chemotherapy with systemic injection of paclitaxel and oral administration of novel dihydropyrimidine- dehydrogenase- inhibitory fluoropyrimidine (S-1). Following 7 courses of the biweekly paclitaxel and S-1 combination chemotherapy, the patient underwent total gastrectomy with D3 extended lymph node dissection. According to the operative findings, the tumor was curatively removed along with the liver metastases and paraaortic lymph node metastases. Biopsy of the liver was performed and the pathological diagnosis indicated no gastric adenocarcinoma cells. The pathological report showed that the lymph node metastases had completely disappeared with single exception and minute cancerous lesions were identified in the gastric mucosa and submucosa. Therefore, the histological efficacy was evaluated as Grade 2. For postoperative chemotherapy, oral S-1 administration only was chosen. However, 6 months later, biweekly paclitaxel and S-1 combination chemotherapy was administered in sequence as a second adjuvant chemotherapy because the serum level of the tumor marker was elevated. The patient is fine and has not shown any recurrence at other sites 37 months after surgery. Salvage surgery following paclitaxel and S-1 chemotherapy may be feasible for patients with advanced gastric cancer and complete regression of distant metastases. Biweekly paclitaxel and S-1 combination chemotherapy has been used safely and its administration may be continued for a long time in an outpatient clinic setting for the treatment of advanced gastric cancer.
