We developed a highly accurate tool that uses basic clinical and analytical information to predict the probability of survival at 15, 30, and 60 days in terminally ill cancer patients. This tool can help physicians making decisions on clinical care at the end of life.
The purpose of this study was to evaluate cisplatin nephrotoxicity in patients 70 years and older and to identify factors influencing nephrotoxicity occurrence. Forty-nine (N = 49) patients older than 70 years were studied retrospectively. All patients received treatment with cisplatin. Variables under study were as follows: prechemotherapy serum creatinine levels (Crb), maximum serum creatinine level during treatment (Crmax), steady serum creatinine level 3 months after treatment completion (Crstb), as well as their corresponding creatinine clearance values (CrbC, CrmaxC, CrstbC) as calculated by the Cockroft and Gault formula. Maximum creatinine increment (Imax = Crmax - Crb), stable creatinine increment (Istb = Crstb - Crb) and the corresponding clearance decrements (Dmax and Dstb) were calculated as well. The potential relationship of the above variables to cisplatin dose intensity and accumulated dose as well as to different prognostic factors were also considered. Assessment of associated conditions was carried out by means of Charlson comorbidity index. The patients' mean age was 73 years (range: 70-79 years). There were 43 men (88%) and 6 women (12%). Mean cisplatin dose intensity was 27 mg/m2/wk. A total of 157 chemotherapy courses were administered with a mean of 3.2 per patient. Mean Crb was 1.02 mg/dl (95% CI = 1.02-1.12), mean Crmax was 1.45 (95% CI = 1.34-1.46), and mean Crstb was 1.24 (95% CI = 1.16-1.32). Imax was equal to 0 in 13 patients (26%) and more than 0.4 mg/dl in 21 patients (43%). Istb was equal to 0 or negative in 22 (45%) and more than 0.4 in only 9 patients (18.3%). No significant relationship of serum creatinine levels, creatinine clearance levels, or of their increments or decrements to cisplatin dose intensity or accumulated dose were found. These levels also did not correlate with age, sex, comorbidity or Eastern Cooperative Oncology Group score. In 85% of patients, Crmax was reached between chemotherapy initiation and the third chemotherapy course, and thereafter renal function began to recover despite continued administration of cisplatin. Cisplatin is well tolerated by patients 70 years and older and dose intensity does not seem to influence renal function deterioration. Therefore, we failed to find reasons to encourage modification or limitation of cisplatin treatment in the elderly population.
Background: Approximately 15% of patients infected by SARS-CoV-2 develop a distress syndrome secondary to a host hyperinflammatory response induced by a cytokine storm. Myelosuppression is associated with a higher risk of infections and mortality. There are data to support methods of management for neutropenia and COVID-19. We present a multicenter experience during the first COVID-19 outbreak in neutropenic cancer patients infected by SARS-CoV-2. Methods: Clinical retrospective data were collected from neutropenic cancer patients with COVID-19. Comorbidities, tumor type, stage, treatment, neutropenia severity, G-CSF, COVID-19 parameters, and mortality were analyzed. A bivariate analysis of the impact on mortality was carried out. Additionally, we performed a multivariable logistic regression to predict respiratory failure and death. Results: Among the 943 cancer patients screened, 83 patients (11,3%) simultaneously had neutropenia and an infection with COVID-19. The lungs (26%) and breasts (22%) were the primary locations affected, and most patients had advanced disease (67%). In the logistic model, as adjusted covariates, sex, age, treatment (palliative vs. curative), tumor type, and the lowest level of neutrophils were used. A significant effect was obtained for the number of days of G-CSF treatment (OR = 1,4, 95% CI [1, 1, 03, 92], p-value = 0.01). Conclusions: Our findings suggest that a prolonged G-CSF treatment could be disadvantageous for these cancer patients with infections by COVID-19, with a higher probability of worse outcome.
More than 50 % of patients with colorectal cancer develop liver metastases. Surgical resection is the only available treatment that improves survival in patients with colorectal liver metastases (CRLM). New antiangiogenic targeted therapies, such as bevacizumab, aflibercept, and regorafenib, in combination with neoadjuvant and conversion chemotherapy may lead to improved response rates in this population of patients and increase the proportion of patients eligible for surgical resection. The present review discusses the available data for antiangiogenic targeted agents in this setting. One of these therapies, bevacizumab, which targets the vascular endothelial growth factor (VEGF) has demonstrated good results in this setting. In patients with initially unresectable CRLM, the combination of 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) plus bevacizumab has led to high response and resection rates. This combination is also effective for patients with unresectable CRLM. Moreover, the addition of bevacizumab to chemotherapy in the neoadjuvant setting of liver metastasis has a higher impact on pathological response rate. This drug also has a manageable safety profile, and according to recent data, bevacizumab may protect against the sinusoidal dilation provoked in the liver by certain cytotoxic agents. In phase II trials, antiangiogenic therapy has demonstrated benefits in the presurgical treatment of CRLM and may represent a new treatment pathway for these patients.
