    Background: An accurate estimate of the likelihood of serious complications in patients with otherwise apparently stable febrile neutropenia (FN) may assist in decision-making regarding individualized therapy. Our group has developed a prognostic score for predicting complications in patients with solid tumors and apparently stable episodes called CISNE (Clinical Index for Stable Febrile Neutropenia). The purpose of this study is to present a nomogram based on the previously mentioned index in a broader dataset of patients. Methods: FINITE is a prospective and multicenter study which aims to investigate prognostic factors and outcomes of FN episodes with clinical stability at first assessment, defined as events without acute organ dysfunction, vital signs abnormalities or major infections. We performed a nomogram based on the CISNE score which includes the following prognostic variables: ECOG PS≥2, chronic obstructive pulmonary disease, cardiovascular disease, mucositis NCI grade ≥2, monocytes <200/mm3 and stress-induced hyperglycemia. A calibration plot was used to analyze the accuracy of this multivariate nomogram. Results: From October 2012 to December 2013, 781 patients with apparently stable FN were recruited in 21 Spanish hospitals. The rate of infection-related complications and death was 15.6% (95% confidence interval [CI], 12.9-18.6%) and 1.7% (95% CI, 0.98%-3.01%). A nomogram was designed according to the CISNE score. The area under the ROC curve was 0.836 (95% CI, 0.808-0.861). The observed and predicted probabilities also matched closely. Conclusions: Our group has developed a user-friendly nomogram for predicting complications in patients with apparently stable FN. This nomogram may be particularly useful to prevent premature discharges of cancer patients starting inpatient management.

    Pathological complete response to neoadjuvant chemotherapy, but not the addition of carboplatin, is associated with improved survival in Chilean triple negative breast cancer patients: a report of real world data
    (2021) Walbaum, Benjamin; Acevedo, Francisco; Median, Lidia; Bravo, M. Loreto; Merino, Tomas; Camus, Mauricio; Dominguez, Francisco; Mondaca, Sebastián; Galindo, Héctor; Nervi, Bruno; Ibañez, Carolina; Madrid, Jorge; Muñiz, Sabrina; Peña, José; Koch, Érica; Garrido, Marcelo; Pinto, Mauricio P.; Sánchez, César
    Background: Breast cancer (BC) is the leading cause of cancer death for Chilean women. About 11% of cases are triple-negative (TN) BC. These are characterised by poor prognosis, higher risk of early recurrence and visceral dissemination versus other BC subtypes. Current standard treatment for early-stage non-metastatic TNBC patients consists of neoadjuvant chemotherapy (NACT) followed by surgery and radiotherapy. Pathological complete response (pCR) to NACT is associated with an increase in survival rates. In general, NACT and adjuvant regimens involve similar cytotoxic drugs. Recent studies have postulated that the use of platinum compounds in TNBC would increase response rates. However, their effects on patient survival remain uncertain. Materials and methods: We retrieved and analysed medical records from a total of 156 Chilean stage I–III TNBC female patients that received NACT and compared survival rates using carboplatin (Cb)-containing versus non-Cb-containing regimens at two health cancer centres. Results: Median age was 51 years (range: 24–81); 13.5% (n = 21) received Cb-containing regimens, 80.1% (n = 125) received sequential anthracyclines plus taxanes; 29.5% (n = 46) of the total group achieved pCR, 28% for the standard treatment and 35% (n = 8) for the Cb-containing group (p = 0.59). We confirmed pCR was associated with prolonged overall survival, invasive and distant disease-free survival (Log-rank p = 0.0236). But the addition of Cb was not associated with differences in survival measures (Log-rank p = 0.5216). Conclusions: To the best of authors’ knowledge, this is the first report on real-world data in the Chilean population assessing the effect of Cb-containing NACT in TNBC. The authors’ results suggest no survival benefit by the addition of Cb to standard NACT. However, we confirm an increase in survival associated to pCR regardless of treatment.
