s-1-(combination) and Inflammation

The purpose of this study was to assess the efficacy and safety of fixed dose rate infusion of gemcitabine and S-1 combination therapy (FGS) in patients with gemcitabine (GEM)-refractory pancreatic cancer (PC) and to explore independent variables associated with survival.. We retrospectively reviewed consecutive patients with GEM-refractory PC who received FGS at our institution from March 2009 to December 2013. GEM was administered by fixed dose rate intravenous infusion of 1,200 mg/m(2) as a 120-min infusion on day 1, and S-1 was administered orally twice a day at a dose of 40 mg/m(2) on days 1-7. Cycles were repeated every 14 days.. Sixty-one patients with GEM-refractory PC received FGS. Sixteen patients received FGS as third-line treatment. Twenty-nine patients (48 %) had a history of S-1 administration. The objective response rate was 13 %, and the disease control rate was 49 %. The median progression-free survival time was 2.7 months, and the median overall survival time was 6.0 months. Major Grade 3 or 4 adverse events included neutropenia (15 %), diarrhea (3 %), anorexia (2 %), and fatigue (2 %). A high inflammation-based prognostic score (modified Glasgow prognostic score (mGPS), which incorporates C-reactive protein and albumin), a performance status >0, and serum carbohydrate antigen 19-9 level >2,000 IU/ml were independently associated with a poor outcome.. FGS might be effective and well tolerated as salvage chemotherapy in a practical setting. The inflammation-based prognostic score is a simple and reliable indicator of survival in the setting of salvage chemotherapy.

This study was conducted to determine the prognostic value of the Glasgow Prognostic Score (GPS), an inflammation-based prognostic score composed of C-reactive protein and albumin, for patients with advanced cancer.. A total of 83 advanced gastric cancer patients receiving biweekly docetaxel/S-1 treatment (DS) were included in the study. To identify the value of GPS as prognostic factor for disease-specific survival (DSS) and progression-free survival (PFS), univariate and multivariate analyses were performed.. Unresectable tumors were observed in 78 patients and recurrent tumors were detected in 5 patients. Of these, 12 patients underwent gastrectomy. There were significant correlations between the GPS and the neutrophil/lymphocyte ratio. Univariate analysis revealed that the GPS, Eastern Cooperative Oncology Group performance status and gastrectomy after DS treatment significantly affected prognosis. Multivariate analysis showed that the GPS, age and gastrectomy independently influenced DSS, and that the GPS and gastrectomy also influenced PFS. Multivariate analysis restricted to patients without gastrectomy showed that the GPS and age independently affected DSS, and that the GPS influenced PFS.. In the low GPS group, it may be possible to obtain favorable outcomes by chemotherapy in advanced gastric cancer patients. However, a well-designed prospective trial in a large patient cohort is required to corroborate the prognostic value of the GPS.

We experienced a case of inflammatory carcinoma, which has been well controlled by chemotherapy, especially, vinorelbine, S-1 and trastuzumab. A 54-year-old woman was diagnosed as inflammatory carcinoma with T4d, N3c, M0 in Stage III c. The lesion was diagnosed as invasive ductal carcinoma, scirrhous, ER(-), PgR(-), HER2(3+) by core needle biopsy, The skin lesion was diagnosed as dermal lymphatic carcinomatosis by skin biopsy. The following chemotherapy was performed: FEC(5-FU 500 mg/m2, epirubicin 70 mg/m2, cyclophosphamide 500 mg/m2) followed by docetaxel(DOC 70 mg/m/2), every 3 weeks, each 6 times; after that, sequentially, vinorelbine (25 mg/m2)+trastuzumab (2 mg/kg every week), UFT(300 mg, daily)+cyclophosphamide (100 mg 2 weeks on, 1 week off)+trastuzumab (continued) and S-1 (120 mg/body 4 weeks on, 2 weeks off)+trastuzumab (continued). The patient has been well controlled by the chemotherapy with good QOL. Especially vinorelbine, S-1, and trastuzumab contributed to the disappearance of skin lesion.

S-1 is an oral antineoplastic agent that contains a prodrug of 5-fluorouracil and has adverse effects on skin, alimentary tract mucosa, and the ocular surface. We investigated the effects of S-1 on the corneal epithelium by in vivo confocal microscopy and histopathologic analysis.. Twelve patients with eye problems related to S-1 treatment participated in the study. Twenty eyes of ten subjects were evaluated by laser-scanning confocal microscopy. Corneal epithelial debridement as a diagnostic therapy and histopathologic analysis were performed for five eyes of three subjects affected in the pupillary zone of the cornea.. Slitlamp examination revealed a local limbal abnormality characterized by epithelial invasion toward the center of the cornea in all 24 eyes. In vivo confocal microscopy revealed an altered structure of the corneal epithelium with abnormal epithelial cells and inflammation. One of five specimens subjected to cytologic diagnosis showed moderate dysplasia. Hematoxylin and eosin staining showed that each abnormal epithelial sheet lacked the stratified structure of the normal corneal epithelium. Immunofluorescence analysis revealed the presence of cells positive for one, both, or neither of cytokeratins 12 and 4 in each lesion.. S-1 can induce ocular mucositis with dysplasia, likely affecting cellular functions, including differentiation, of the corneal epithelium. In vivo confocal microscopy allowed the noninvasive detection of cellular changes in the cornea as an adverse effect of S-1 administration.

S-1 was administered to male and female rats by gavage for 26 weeks at 0, 1, 5, and 10 mg/kg/day followed by 5-week recovery period for the control, 5, and 10 mg/kg/day groups. Treatment at 5 or 10 mg/kg/day in both sexes produced keratosis of the tail, palm or sole. Weight gain and average food consumption were lowered by the treatment. Urine showed increases in protein and epithelial or white blood cells and a decrease in specific gravity. The blood showed decreases in red blood cell count, hemoglobin, and hematocrit as well as increases in MCH, platelet count, fibrinogen, and MCV. A/G ratio, albumin, and chloride were decreased while total cholesterol, free cholesterol, triglycerides, and phospholipids were increased. Histopathologically, treatment-related changes at 5 and 10 mg/kg/day were observed mainly in the lymphoid tissues and kidneys. Those changes included atrophy in the lymphoid tissues and chronic nephropathy-like changes in the kidneys. Other changes in the 10 mg/ kg/day group, included acanthosis and/or inflammation in the epidermis of the tail, sole, or palm, degeneration and disarrangement of ameloblasts, and atrophy of the testes. In a recovery study, although some changes in the sole, palm, or tail, and the kidneys remained, they were less extensive than they had been at the end of the treatment period. Based upon these observations, the non-toxic dose level was estimated to be 1 mg/kg/day (2.3 mg/kg/day, as the summed doses of tegafur, CDHP, and Oxo) in both sexes.
