          Abstract

          Clinical effects of FOLFOX4 and TPF chemotherapy regimen on postoperative gastric cancer patients were investigated. A total of 60 patients admitted to the First People's Hospital of Changzhou receiving gastric cancer operation were selected and they were divided into two groups at random. Thirty patients in the FOLFOX4 group were treated with oxaliplatin, fluorouracil and leucovorin, while 30 patients in the TPF group were treated with paclitaxel, fluorouracil and cisplatin. The therapeutic effects, adverse reactions, quality of life and survival time of patients in the two groups were observed. The total effective rate of the FOLFOX4 group was 73.3%, which was significantly higher than that of the TPF group (43.3%), and the difference was statistically significant (P<0.05). The proportions of neurotoxicity and thrombocytopenia in the FOLFOX4 group were 56.7 and 33.3%, while those in the TPF group were 26.7 and 60%, respectively, and the differences were statistically significant (P<0.05). The increasing proportion of postoperative scores of the FOLFOX4 group was 46.7%, which was significantly higher than that of the TPF group (20%), and the difference was statistically significant (P<0.05). The 2- and 3-year survival rates of the FOLFOX4 group were 63.3 and 50%, which were significantly higher than those of the TPF group (36.7 and 23.3%), and the differences were statistically significant (P<0.05). Therefore, the effective rate of FOLFOX4 regimen is high in the treatment of gastric cancer with relatively fewer adverse reactions, which has a certain advantage.

          A phase II study of biweekly oxaliplatin plus infusional 5-fluorouracil and folinic acid (FOLFOX-4) as first-line treatment of advanced gastric cancer patients

          The aim of the study was to assess the toxicity and the clinical activity of biweekly oxaliplatin in combination with infusional 5-fluorouracil (5-FU) and folinic acid (FA) administered every 2 weeks (FOLFOX-4 regimen) in patients with advanced gastric cancer (AGC). A total of 61 previously untreated AGC patients were treated with oxaliplatin 85 mg m−2 on day 1, FA 200 mg m−2 as a 2 h infusion followed by bolus 5-FU 400 mg m−2 and a 22 h infusion of 5-FU 600 mg m−2, repeated for 2 consecutive days every 2 weeks. All patients were assessable for toxicity and response to treatment. Four (7%) complete responses and 19 partial responses were observed (overall response rate, 38%). Stable disease was observed in 22 (36%) patients, with progressive disease in the other six (10%) patients. Median time to progression (TTP) and median overall survival (OS) were 7.1 and 11.2 months, respectively. National Cancer Institute Common Toxicity Criteria grade 3 and 4 haematologic toxicities were neutropenia, anaemia and thrombocytopenia in 36, 10 and 5% of the patients, respectively. Grade 3 peripheral neuropathy was recorded in three (5%) patients. FOLFOX-4 is an active and well-tolerated chemotherapy. Response rate (RR), TTP and OS were comparable with those of other oxaliplatin-based regimens, suggesting a role for this combination in gastric cancer.

            Molecular-targeted first-line therapy for advanced gastric cancer.

            Gastric cancer is the fifth most common cancer and third leading cause of cancer-related deaths worldwide. Complete resection of the whole tumor remains the only approach to treat this malignant disease. Since gastric cancer is usually asymptomatic in its early stages, many people are diagnosed at an advanced stage when the tumor is inoperable. In addition, because other conventional treatments (radiotherapy and chemotherapy) have only modest efficacy for those with advanced/metastatic gastric cancer, the prognosis in such cases is poor. Recently, trials have provided some promising results regarding molecular-targeted therapy, raising the possibility that the development of these agents could be a fruitful approach. However, the benefit of molecular-targeted therapy for advanced gastric cancer remains inconclusive.

              Patient preferences for palliative treatment of locally advanced or metastatic gastric cancer and adenocarcinoma of the gastroesophageal junction: a choice-based conjoint analysis study from Germany

              Background Decisions on palliative chemotherapy (CT) for locally advanced or metastatic gastric cancer (mGC) require trade-offs between potential benefits and risks for patients. Healthcare providers and payers agree that patient-preferences should be considered. We conducted a choice-based conjoint (CBC) analysis study in pre-treated patients from Germany with mGC or locally advanced or metastatic adenocarcinoma of the gastroesophageal junction (mGEJ-Ca), to evaluate their preferences when hypothetically selecting a CT regimen. Methods German oncologists and gastroenterologists were contacted to identify patients with mGC or mGEJ-Ca who had completed ≥2 cycles of palliative CT in first or later lines of therapy (CT ongoing or complete). The primary objective was to quantify patient preferences for palliative CT by CBC analysis. Six in-depth qualitative interviews identified 3 attributes: treatment tolerability, quality of life in terms of ability of self-care, and additional survival benefit. The CBC matrix was constructed with 4 factor levels per attribute and each participant was presented with 15 different iterations of these levels. A minimum of 50 participants was needed. Consenting patients completed the CBC survey, choosing systematically among profiles. CBC models were estimated by multinomial logistic regression (MLR) and hierarchical Bayesian (HB) analysis. Estimates of importance for each attribute and factor-level were calculated. Results Fifty-five patients participated in the CBC survey (78.2% male, median age 63 years, 81.8% currently receiving CT). Across this sample, low treatment toxicity was ranked highest (44.6% relative importance, MLR analysis), followed by ability to self-care (32.3%), and an additional survival benefit of up to 3 months (3 months 23.1%, 2 months 18.3%, 1 month 11.2%). The MLR analysis showed high validity (certainty 37.9%, chi square p < 0.01, root-likelihood 0.505). The HB analysis yielded similar results. Conclusions Patients’ preferences related to a new hypothetical palliative CT of mGC or mGEJ-Ca can be assessed by CBCanalysis. Although in real-life, patients initially need to decide on CT before they have any experience, and patients’ varied experiences with CT will have impacted specific responses, low toxicity and self-care ability were considered as most important by this group of patients with mGC or mGEJ-Ca.
