A randomized phase III trial comparing adjuvant single-agent S1, S-1 with oxaliplatin, and postoperative chemoradiation with S-1 and oxaliplatin in patients with node-positive gastric cancer after D2 resection: the ARTIST 2 trial☆.

BACKGROUND: Adjuvant chemotherapy and chemoradiotherapy are some of the standards of care for gastric cancer (GC). The Adjuvant chemoRadioTherapy In Stomach Tumors (ARTIST) 2 trial compares two adjuvant chemotherapy regimens and chemoradiotherapy in patients with D2-resected, stage II or III, node-positive GC. PATIENTS AND METHODS: The ARTIST 2 compared, in a 1:1:1 ratio, three adjuvant regimens: oral S-1 (40-60 mg twice daily 4 weeks on/2 weeks off) for 1 year, S-1 (2 weeks on/1 week off) plus oxaliplatin 130 mg/m2 every 3 weeks (SOX) for 6 months, and SOX plus chemoradiotherapy 45 Gy (SOXRT). Randomization was stratified according to surgery type (total or subtotal gastrectomy), pathologic stage (II or III), and Lauren histologic classification (diffuse or intestinal/mixed). The primary endpoint was disease-free survival (DFS) at 3 years; a reduction of 33% in the hazard ratio (HR) for DFS with SOX or SOXRT, when compared with S-1, was considered clinically meaningful. The trial is registered at clinicaltrials.gov (NCT0176146). RESULTS: A total of 546 patients were recruited between February 2013 and January 2018 with 182, 181, and 183 patients in the S-1, SOX, and SOXRT arms, respectively. Median follow-up period was 47 months, with 178 DFS events observed. Estimated 3-year DFS rates were 64.8%, 74.3%, and 72.8% in the S-1, SOX, and SOXRT arms, respectively. HR for DFS in the control arm (S-1) was shorter than that in the SOX and SOXRT arms: S-1 versus SOX, 0.692 (P = 0.042) and S-1 versus SOXRT, 0.724 (P = 0.074). No difference in DFS was found between SOX and SOXRT (HR 0.971; P = 0.879). Adverse events were as anticipated in each arm, and were generally well-tolerated and manageable. CONCLUSIONS: In patients with curatively D2-resected, stage II/III, node-positive GC, adjuvant SOX or SOXRT was effective in prolonging DFS, when compared with S-1 monotherapy. The addition of radiotherapy to SOX did not significantly reduce the rate of recurrence after D2 gastrectomy.

Patient satisfaction with treatments for moderate-to-severe plaque psoriasis in clinical practice.

BACKGROUND: Treatment satisfaction among patients with moderate-to-severe psoriasis has not been studied and compared across treatments using a validated instrument. OBJECTIVES: To assess patient-reported satisfaction with systemic and phototherapy treatments for moderate-to-severe psoriasis in clinical practice and to correlate satisfaction with disease severity and quality-of-life measures. METHODS: This was a cross-sectional study of 1182 patients with moderate-to-severe psoriasis in the Dermatology Clinical Effectiveness Research Network in the U.S.A. Patients receiving either topical therapies only; monotherapy with oral systemic therapies, biologics or narrowband ultraviolet B phototherapy; or combination therapy with biologics and methotrexate completed the Treatment Satisfaction Questionnaire for Medication version II. RESULTS: Median unadjusted overall satisfaction scores were highest for patients receiving biologic monotherapies, biologic-methotrexate combinations, or phototherapy (83.3); scores were lowest for those receiving topical therapies only or acitretin (66.7). In fully adjusted models, compared with patients receiving methotrexate monotherapy, those receiving adalimumab, etanercept, ustekinumab, phototherapy or adalimumab with methotrexate had significantly higher median overall satisfaction scores by 7.2-8.3 points, while those receiving topical therapies only had significantly lower overall satisfaction by 8.9 points. Adjusted convenience scores were lowest for patients receiving topical therapies only or infliximab. Modest but significant correlations were found between the overall satisfaction subscale and both the Psoriasis Area and Severity Index (ρ = -0.36, P < 0.001) and the Dermatology Life Quality Index (ρ = -0.47, P < 0.001). CONCLUSIONS: Discernible differences were found in treatment satisfaction among therapies, particularly regarding treatment effectiveness and convenience. Further application of treatment satisfaction measures may inform treatment decisions and guideline development.

Clinical impacts of tumor cell contamination of hematopoietic stem cell products in metastatic breast cancer patients undergoing autologous peripheral blood stem cell transplantation: multicenter trial.

To determine whether the tumor cell contamination of peripheral blood stem cells influences clinical impacts on high-dose chemotherapy in patients with metastatic breast cancer, we analyzed carcinoembryonic antigen (CEA) mRNA in the apheresis products by nested RT-PCR (reverse transcriptase-polymerase chain reaction). A total of 38 metastatic breast cancer patients and ten normal healthy subjects as a negative control were included. Twenty out of 38 (51.3%) apheresis products from patients with metastatic breast cancer were positive for CEA mRNA. CEA mRNA was noted in 54.8% (17/31) of patients mobilized with chemotherapy plus G-CSF and 42.8% (3/7) of patients with G-CSF alone. There was no significant difference in age, estrogen receptor, menopausal status, mobilization method, disease free interval, or number of metastasis sites (1 vs > or = 2) between positive and negative groups. The presence of CEA mRNA in apheresis products did not influence the time to progression and overall survival in both groups. However, both the univariate and the multivariate analysis disclosed that the number of metastasis was associated with survival significantly. We suggest that the tumor cell contamination does not predict poor treatment outcome in patients with metastatic breast cancer.
