Abstract
BACKGOUND Little information regarding to the survival advantage of third-line chemotherapy in advanced gastric cancer patients is available. The current study is designed to systematically review and perform meta-analysis on the effect of third-line chemotherapy on progressive or recurrent gastric cancer treatment. METHODS After thorough searching of online databases, total 20 articles were included into qualitative systematic review and 6 of them were used to conduct qualitative meta-analysis. RESULTS It was found that the third-line chemotherapy was superior to placebo or best supportive care in terms of prolonging median oval survival (OS) length and progress free survival (PFS) length (Hedges's g for OS = -0.315 ± 0.077, P < .001; and for PFS = -0.382 ± 0.098, P < .001). In addition, the third-line chemotherapy was favored (Hedges's g = 0.848, P < .001) in terms of overall survival rate (Hazard ratio = 0.679, 95% confidence interval: 0.565-0.816, P < .001) or tumor free survival rate (Hazard ratio = 0.561, 95% confidence interval: 0.444-0.709, P < .001). CONCLUSION The third-line chemotherapy is superior to the best supportive care in advanced gastric cancer patients who had been pretreated with first-line and second-line chemotherapy.

Irinotecan combined with 5-fluorouracil and leucovorin third-line chemotherapy after failure of fluoropyrimidine, platinum, and taxane in gastric cancer: treatment outcomes and a prognostic model to predict survival. Gastric Cancer 2013; 16:581-9. [PMID: 23266882 DOI: 10.1007/s10120-012-0227-5] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2012] [Accepted: 11/27/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this study was to evaluate the activity and safety of the combination chemotherapy of 5-fluorouracil (5-FU), leucovorin, and irinotecan (FOLFIRI regimen) after failure of fluoropyrimidine, platinum, and taxane in gastric cancer (GC) and to evaluate the prognostic factors for survival. METHODS Patients received biweekly FOLFIRI chemotherapy as third-line treatment. The FOLFIRI-1 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (200 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 600 mg/m(2) in a 22-h continuous infusion) on days 1 and 2. FOLFIRI-2 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (400 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 2400 mg/m(2) in a 46-h continuous infusion) on day 1. RESULTS A total of 158 patients were included. The overall response rate was 9.6 % in patients with measurable lesions. The median progression-free survival (PFS) and overall survival (OS) were 2.1 months [95 % confidence interval (CI), 1.7-2.5] and 5.6 months (95 % CI, 4.7-6.5), respectively. The major grade 3/4 toxicity was myelosuppression (36.7 %). Good performance status (PS), fewer metastatic sites, and longer duration from the first-line to third-line chemotherapy were independent prognostic factors affecting both PFS and OS. CONCLUSIONS The FOLFIRI regimen showed antitumor activity and tolerable toxicity profiles against advanced GC in the third-line setting. Patients with good PS, fewer metastatic sites and longer previous treatment duration might have the maximal benefit from third-line chemotherapy.

Outcomes of third-line docetaxel-based chemotherapy in advanced gastric cancer who failed previous oxaliplatin-based and irinotecan-based chemotherapies. Cancer Res Treat 2012; 44:235-41. [PMID: 23341787 PMCID: PMC3546270 DOI: 10.4143/crt.2012.44.4.235] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2012] [Accepted: 08/23/2012] [Indexed: 12/15/2022] Open
Abstract
Purpose Little is known about outcomes in the use of third-line chemotherapy in cases of advanced gastric cancer (AGC). The primary aim of this retrospective study was to evaluate outcomes of docetaxel-based chemotherapy in patients with AGC that progressed after both oxaliplatin-based and irinotecan-based regimens. Materials and Methods Eligible patients were those with AGC who had previous chemotherapy including fluoropyrimidine and oxaliplatin as well as fluoropyrimidine and irinotecan and who received subsequent docetaxel-based chemotherapy. Thirty-five patients were retrospectively recruited from 5 medical centers in Korea. Patients received either weekly or 3 weekly with docetaxel +/- cisplatin. Results Thirty-one out of 35 patients were evaluated for treatment response. A total of 94 cycles of chemotherapy (median, 2; range, 1 to 7) were administered. The overall response rate was 14.3%, and the disease control rate was 45.7%. The median progression-free survival (PFS) was 1.9 months (95% confidence interval [CI], 1.1 to 2.7 months). The median overall survival (OS) was 3.6 months (95% CI, 2.8 to 4.4 months). PFS and OS were significantly prolonged in patients of the Eastern Cooperative Oncology Group, with performance status of 0 or 1 in multivariate analysis (PFS: hazard ratio[HR], 0.411; 95% CI, 0.195 to 0.868; p=0.020 and OS: HR, 0.390; 95% CI, 0.184 to 0.826; p=0.014, respectively). Four of the 35 patients enrolled in the study died due to infection associated with neutropenia. Conclusion Our findings suggest that salvage docetaxel-based chemotherapy is a feasible treatment option for AGC patients with good performance status (PS), whereas chemotherapy for patients with poor PS (PS≤2) should be undertaken with caution for those who previously failed oxaliplatin- and irinotecan-based regimens.

Abstract
Stomach cancer is still one of the most prevalent malignancies and is the main cause of cancer deaths worldwide. The outcome for patients with metastasis, as well as for those with tumor recurrence, is dismal, with median survival time not greater than a year. Patients with unresectable locally advanced or metastatic lesions have been treated with systemic chemotherapy, and several randomized studies have demonstrated the benefit of chemotherapy compared with best supportive care. Recently, randomized phase III trials have presented a benefit of second-line chemotherapy compared with supportive care alone. However, it is not known at present which drug is the most effective in this setting. In Korea, the practice of offering second-line treatment to patients with advanced gastric cancer (AGC) is common, and many prospective clinical trials investigating clinical outcomes of second-line chemotherapy have been reported. Therefore, to define the potential role of second-line chemotherapy and to help to select an effective regimen, we review the published Korean prospective data concerning the use of chemotherapy in the second-line setting for the treatment of AGC. No phase III trials but 20 phase II trials were identified. The benefit of second-line chemotherapy in AGC has indirect evidence considering prolongation of progression-free survival (PFS) and improvement of the response rate. Taxanes, irinotecan, and oxaliplatin have been studied much and might be promising drugs considering cross-resistance to a 5-fluorouracil and cisplatin combination (FP). A large, prospective, multicenter, randomized phase III study is warranted to select the most effective second-line chemotherapeutic agents.

Abstract
Background: To assess the efficacy and safety of individualised dose optimisation of irinotecan monotherapy as salvage treatment for advanced gastric cancer (AGC). Methods: A total of 43 patients were enrolled. Intravenous irinotecan (350 mg m−2) was administered every 3 weeks. The dose was increased (425 mg m−2 and 500 mg m−2) or decreased (250 mg m−2) depending on patient tolerance. UGT1A1 genotypes were determined by direct sequencing of genomic DNA extracted from peripheral blood. Results: A total of 183 cycles of irinotecan were administered, with a median of four cycles per patient. The overall response rate was 9.3%, and the disease control rate was 62.8%. Median time to disease progression was 2.8 months, and median overall survival was 8.0 months. Grade 3–4 neutropenia was the most common toxicity (53.5%), and febrile neutropenia was the least common toxicity (4.6%). Compared with defective allele groups, UGT1A1 *1/*1 was associated with a lower incidence of grade 3–4 neutropenia during the first cycle (P=0.018). Conclusion: Individualised irinotecan dose escalation based on patient tolerance was not associated with increased toxicity and shows modest activity as salvage chemotherapy for AGC. The role of UGT1A1 genotype in clinical toxicity requires further evaluation.

Abstract
BACKGROUND Preclinical studies have shown that mitomycin C (MMC) acts synergistically with irinotecan (CPT-11). In this phase II study, we evaluated the efficacy and toxicity of MMC/CPT-11 therapy as second-line chemotherapy for patients with fluoropyrimidine-resistant advanced gastric cancer. METHODS Eligible patients had evidence of tumor progression despite prior treatment with fluoropyrimidine-based regimens or had relapsed within 6 months after completion of therapy with adjuvant fluoropyrimidines. Treatment consisted of MMC (5 mg/m(2)) and CPT-11 (150 mg/m(2)) administered i.v. every 2 weeks. The primary endpoint was the response rate (RR). Our hypothesis was that this combination therapy was efficacious when the lower boundary of the 95% confidence interval (CI) of the RR exceeded 20% of the threshold RR. RESULTS Between April 2002 and July 2003, 45 eligible patients were registered and analyzed. Among the 45 patients, 40 (89%) had previously received chemotherapy for metastasis and 24 (53%) had a performance status (PS) of 0. Thirteen partial responses were obtained among the 45 patients, resulting in an overall RR of 29% (95% CI, 16-42%). The median time to progression was 4.1 months, and the median survival time was 10 months, with a 1-year survival rate of 36%. Grade 4 neutropenia was observed in 29% of the patients, whereas febrile neutropenia occurred in 9%. The incidence rates of grade 3 nausea and diarrhea were 13 and 2%, respectively. CONCLUSIONS Although this study did not achieve the per-protocol definition of activity, the progression-free survival and overall survival appeared to be promising, with acceptable tolerability. Thus, MMC/CPT-11 therapy as second-line chemotherapy for fluoropyrimidine-resistant advanced gastric cancer presents a potential treatment option in patients with a good PS.

Abstract
Progress in gastric cancer has been slow, but steady. Historically, patients commonly presented with significant disease related co-morbidity and received treatment of marginal benefit but unfortunately associated with significant toxicity. Today there is no universally accepted reference standard chemotherapy for this disease. However, there is reason for optimism. Meta-analyses of randomized trials have shown a benefit for first-line combination chemotherapy. Current three drug chemotherapy regimens remain toxic, though perhaps less so than previously, and can result in a small but significant survival advantage in carefully chosen patients. Incremental improvements have been observed in both treatment-related toxicity and survival after first-line therapy. More patients are candidates for chemotherapy beyond progression with first-line therapy and response rates with second-line regimens are similar to those seen in other solid tumor malignancies. Although there is no randomized data to support its use second-line treatment should be considered in appropriate patients. Even before the integration of targeted therapies in the treatment of gastric cancer, it was evident that survival for more than 2 years is possible in a subset of patients and large retrospective studies have highlighted clinicopathologic factors associated with improved survival. Presently, with the addition of targeted therapy, especially anti-angiogenic and anti-Her2 therapy, and a better understanding of the biology of the disease, perhaps a sense of optimism should indeed suppress the nihilism commonly associated with this disease.

Abstract
Gastric cancer remains one of the most common forms of cancer worldwide. Unfortunately, most patients will present with advanced-stage disease, and will therefore need palliative chemotherapy. Some chemotherapy regimens have been well established as first-line therapy, and have been shown to increase survival; however, almost all patients with metastatic gastric cancer will develop progressive disease after first-line therapy. With the availability of several active chemotherapy drugs, many patients who retain a good performance status after the initial treatment remain good candidates for additional therapy; however, no standard approach for second-line therapy exists. Many small, phase 2 trials have been done and the findings are variable. No data from randomised-controlled trials suggest a benefit of second-line chemotherapy compared with supportive care alone. We review the published data concerning the use of chemotherapy in the second-line setting for the treatment of advanced gastric cancer.

Abstract
BACKGROUND A better method for detecting early peritoneal progression is needed. This study evaluated the feasibility and accuracy of second-look laparoscopy for patients with gastric cancer treated using systemic chemotherapy after gastrectomy. METHODS Second-look laparoscopy was conducted for patients who had no clinical evidence of distant metastases but had peritoneal metastases or positive peritoneal cytology results without visible metastatic disease at initial surgery, patients who underwent systemic chemotherapy over a 6-month period after surgery, and patients who had no clinical evidence of disease based on imaging study after completion of primary chemotherapy. RESULTS Between November 2004 and April 2008, 21 patients underwent second-look laparoscopy. At the initial surgery, 13 of these patients underwent total gastrectomy and 8 patients underwent distal gastrectomy. One or two sheets of adhesion barrier were received by 18 patients. The median interval between initial surgery and second-look laparoscopy was 9.8 months (range, 6.6-17.5 months). All second-look procedures were completed laparoscopically, and no patients required conversion to laparotomy. None of the 21 patients experienced postlaparoscopy complications. Whereas 12 patients showed no pathologic evidence of disease, 9 patients showed disease at second-look laparoscopy. There was a significant difference in median survival between the groups with negative and positive results (p = 0.017). The median survival for the negative group has not been determined. All the patients in the positive group received further chemotherapy while showing a good performance status (PS). Six patients were PS 0, and 3 patients were PS 1. The median survival time for this group was 10.1 months. CONCLUSIONS Second-look laparoscopy was a safe and promising approach to reassessment of peritoneal disease for patients with gastric cancer. The incidence of complications was low, particularly in this group of patients, all of whom had undergone prior gastrectomy.

Abstract
The role of nuclear factor-kappaB (NF-kappaB) activation in cancer cell apoptosis appears to be tailored specifically for each cell type and the type of NF-kappaB inducer. The present study aimed to determine whether or not NF-kappaB activation is associated with chemosensitivity to doxorubicin (DOX) using the DOX-sensitive SNU-601 and DOX-resistant SNU-216 gastric cancer cell lines. The effect of NF-kappaB activation on DOX (1 microg/mL) sensitivity was analyzed after the suppression of NF-kappaB activation using transfection of the super-suppressive mutant form of IkappaBalpha (mIkappaBalpha) or pretreatment with pyrrolidine dithiocarbamate. In addition, the association between NF-kappaB and manganese superoxide dismutase (MnSOD) in relation to DOX sensitivity was analyzed after the modulation of MnSOD expression. The NF-kappaB activity was much higher in DOX-resistant SNU-216 cells than in DOX-sensitive SNU-601 cells before and after DOX treatment. Overexpression of mIkappaBalpha or pyrrolidine dithiocarbamate pretreatment decreased the DOX resistance in SNU-601 cells with low MnSOD expression, but not in SNU-216 cells with high MnSOD expression. In comparison, the overexpression of MnSOD, which also suppressed NF-kappaB activation in both cell lines, increased DOX resistance in SNU-601 cells. Blocking of MnSOD expression using RNA interference techniques increased DOX sensitivity in SNU-216 cells, which was further augmented by the additional inhibition of NF-kappaB activity. Our results showed that whether NF-kappaB contributes to DOX sensitivity in gastric cancer cells is determined by the level of MnSOD expression. Thus, targeting both MnSOD and NF-kappaB may be helpful for increasing the efficacy of DOX treatment of DOX-resistant SNU gastric cancer cells.
