RESUMO

BACKGROUND: Although anthracycline-based triplets are one of the most widely used schedules to treat advanced gastric cancer (AGC), the benefit of including epirubicin in these therapeutic combinations remains unknown. This study aims to evaluate both the efficacy and tolerance of triplets with epirubicin vs. doublets with platinum-fluoropyrimidine in a national AGC registry. METHODS: Patients with AGC treated with polychemotherapy without trastuzumab at 28 hospitals in Spain between 2008 and 2016 were included. The effect of anthracycline-based triplets against doublets was evaluated by propensity score matching (PSM) and Cox proportional hazards (PH) regression. RESULT: A total of 1002 patients were included (doublets, n = 653; anthracycline-based triplets, n = 349). The multivariable Cox PH regression failed to detect significantly increased OS in favor of triplets with anthracyclines: HR 0.90 (95% CI, 0.78-1.05), p = 0.20035. After PSM, the sample contained 325 pairs with similar baseline characteristics. This method was also unable to reveal an increase in OS: 10.5 (95% CI, 9.7-12.3) vs. 9.9 (95% CI, 9.2-11.4) months, HR 0.91 (CI 95%, 0.76-1.083), and (log-rank test, p = 0.226). Response rates (42.1 vs. 33.1%, p = 0.12) and PFS (HR 0.95, CI 95%, 0.80-1.13, log-rank test, p = 0.873) were not significantly higher with epirubicin-based regimens. The triplets were associated with greater grade 3-4 hematological toxicity, and increased hospitalization due to toxicity by 68%. The addition of epirubicin is viable, but 23.7% discontinued treatment because of adverse effects or patient decision. CONCLUSION: Anthracyclines added to platinum-fluoropyrimidine doublets did not improve the response rate or survival outcomes in patients with AGC but entailed greater toxicity.

RESUMO

BACKGROUND: To develop and validate a nomogram and web-based calculator to predict overall survival (OS) in Caucasian-advanced oesophagogastric adenocarcinoma (AOA) patients undergoing first-line combination chemotherapy. METHODS: Nine hundred twenty-four AOA patients treated at 28 Spanish teaching hospitals from January 2008 to September 2014 were used as derivation cohort. The result of an adjusted-Cox proportional hazards regression was represented as a nomogram and web-based calculator. The model was validated in 502 prospectively recruited patients treated between October 2014 and December 2016. Harrell's c-index was used to evaluate discrimination. RESULTS: The nomogram includes seven predictors associated with OS: HER2-positive tumours treated with trastuzumab, Eastern Cooperative Oncology Group performance status, number of metastatic sites, bone metastases, ascites, histological grade, and neutrophil-to-lymphocyte ratio. Median OS was 5.8 (95% confidence interval (CI), 4.5-6.6), 9.4 (95% CI, 8.5-10.6), and 14 months (95% CI, 11.8-16) for high-, intermediate-, and low-risk groups, respectively (P<0.001), in the derivation set and 4.6 (95% CI, 3.3-8.1), 12.7 (95% CI, 11.3-14.3), and 18.3 months (95% CI, 14.6-24.2) for high-, intermediate-, and low-risk groups, respectively (P<0.001), in the validation set. The nomogram is well-calibrated and reveals acceptable discriminatory capacity, with optimism-corrected c-indices of 0.618 (95% CI, 0.591-0.631) and 0.673 (95% CI, 0.636-0.709) in derivation and validation groups, respectively. The AGAMENON nomogram outperformed the Royal Marsden Hospital (c-index=0.583; P=0.00046) and Japan Clinical Oncology Group prognostic indices (c-index=0.611; P=0.03351). CONCLUSIONS: We developed and validated a straightforward model to predict survival in Caucasian AOA patients initiating first-line polychemotherapy. This model can contribute to inform clinical decision-making and optimise clinical trial design.

RESUMO

BACKGROUND: The development of reliable alternatives to conventional hospitalization in patients with cancer would have great clinical and economical value. The aim of the present study was to assess the feasibility of a home-based nursing intervention model as a safe alternative for the management of acute medical complications in cancer patients who would otherwise require conventional hospitalization. PATIENTS AND METHODS: From October 2013 to October 2014, we prospectively evaluated the outcomes of consecutive acute medical episodes treated at home under the home-based intervention program named the Bridge Project (BP). Episodes were classified as "avoided hospitalization in outpatients" (AHO) vs. "reduced hospitalization in inpatients" (RHI). The primary end-point was to assess the rate and causes of BP intervention failure (unplanned hospital readmission or death). RESULTS: Two hundred and forty-six consecutive episodes (52 % AHO and 48 % RHI) involving 203 patients (55 % male; mean age 63 years) were enrolled. The main conditions managed at home were non-neutropenic infections (40 %), febrile neutropenia (20 %), and cancer-related complications (28 %). The median duration of the BP intervention was 5 days (range 1-16 days). No deaths were reported at home. Unplanned hospital readmissions occurred in 9 % of episodes (14 % in AHO vs. 4 % in RHI; p = 0.001). Five of the 22 readmitted patients (22.7 % of the BP failures; 2.5 % of the whole series) died during hospitalization. The BP intervention burden was 1353 days, representing a potential saving of 14 % of days of hospitalization during the study period. CONCLUSIONS: The BP is a safe intervention which can potentially avoid or reduce the length of hospitalization in selected cancer patients with acute medical complications. Our findings support further development of innovative home-based clinical approaches to promote potentially avoidable hospitalization in this setting.
