RESUMO
OBJECTIVE: Exploring the association between frailty and mortality in a cohort of patients with COVID-19 respiratory insufficiency treated with continuous positive airway pressure. METHODS: Frailty was measured using a Frailty Index (FI) created by using the baseline assessment data on comorbidities and body mass index and baseline blood test results (including pH, lactate dehydrogenase, renal and liver function, inflammatory indexes and anemia). FI > 0.25 identified frail individuals. RESULTS: Among the 159 included individuals (81% men, median age of 68) frailty was detected in 69% of the patients (median FI score 0.3 ± 0.08). Frailty was associated to an increased mortality (adjusted HR 1.99, 95% CI 1.02-3.88, p = 0.04). CONCLUSIONS: Frailty is highly prevalent among patients with COVID-19, predicts poorer outcomes independently of age. A personalization of care balancing the risk and benefit of treatments (especially the invasive ones) in such complex patients is pivotal.

BACKGROUND: COVID-19 disease can lead to severe functional impairments after discharge. We assessed the quality of life of invasively ventilated COVID-19 ARDS survivors. METHODS: We carried out a prospective follow-up study of the patients admitted to the Intensive Care Units (ICUs) of a teaching hospital. Patients affected by COVID-19 ARDS who required invasive ventilation and were successfully discharged home were assessed through the telephone administration of validated tests. We explored survival, functional outcomes, return to work, quality of life, cognitive and psychological sequelae. The main variables of interest were the following: demographics, severity scores, laboratory values, comorbidities, schooling, working status, treatments received during ICU stay, complications, and psychological, cognitive, functional outcomes. RESULTS: Out of 116 consecutive invasively ventilated patients, overall survival was 65/116 (56%) with no death occurring after hospital discharge. Forty-two patients were already discharged home with a median follow-up time of 61 (51-71) days after ICU discharge and 39 of them accepted to be interviewed. Only one patient (1/39) experienced cognitive decline. The vast majority of patients reported no difficulty in walking (32/35:82%), self-care (33/39:85%), and usual activities (30/39:78%). All patients were either malnourished (15/39:38%) or at risk for malnutrition (24/39:62%). Exertional dyspnea was present in 20/39 (51%) patients. 19/39 (49%) reported alterations in senses of smell and/or taste either before or after hospitalization. CONCLUSIONS: Invasively ventilated COVID-19 ARDS survivors have an overall good recovery at a 2-months follow-up which is better than what was previously reported in non-COVID-19 ARDS patients.

OBJECTIVES: To assess the safety and efficacy of interleukin (IL)-6 blockade with sarilumab in patients with severe COVID-19 pneumonia and systemic hyperinflammation. METHODS: We conducted an open-label study of sarilumab in severe COVID-19 pneumonia (PaO2/FiO2 <300 mm Hg) with hyperinflammation (elevated inflammatory markers and serum IL-6 levels). Sarilumab 400 mg was administered intravenously in addition to standard of care and results were compared with contemporary matched patients treated with standard of care alone. Clinical improvement, mortality, safety and predictors of response were assessed at 28 days. RESULTS: Twenty-eight patients were treated with sarilumab and 28 contemporary patients receiving standard of care alone were used as controls. At day 28 of follow-up, 61% of patients treated with sarilumab experienced clinical improvement and 7% died. These findings were not significantly different from the comparison group (clinical improvement 64%, mortality 18%; p=NS). Baseline PaO2/FiO2 ratio >100 mm Hg and lung consolidation <17% at CT scan predicted clinical improvement in patients treated with sarilumab. Median time to clinical improvement in patients with lung consolidation <17% was shorter after sarilumab (10 days) than after standard treatment (24 days; p=0.01). The rate of infection and pulmonary thrombosis was similar between the two groups. CONCLUSIONS: At day 28, overall clinical improvement and mortality in patients with severe COVID-19 were not significantly different between sarilumab and standard of care. Sarilumab was associated with faster recovery in a subset of patients showing minor lung consolidation at baseline.

Malnutrition is associated with higher rates of surgical complications, increased anticancer treatment toxicities, longer hospital stays, higher healthcare costs, poorer patient quality of life, and lower survival rates. Nutritional support has been shown to improve all of these outcomes. However, the nutritional care of cancer patients is still suboptimal and several issues remain unresolved. Although the effectiveness of nutritional support depends on the timeliness of intervention, assessment of nutritional status is often delayed and perceived as unimportant. When diagnoses of malnutrition are made, they are rarely recorded in medical records. Hospitals lack medical staff dedicated to clinical nutrition, making it difficult to integrate nutritional care into the multidisciplinary management of cancer patients. Outside the hospital, nutritional support is hampered by heterogeneous reimbursement policies and a lack of adequate community nutrition services. In addition, an increasing number of patients are turning to potentially harmful "anti-cancer" diets as trust in medicine declines. Adopting mandatory nutrition screening, monitoring quality of care metrics, providing nutrition education to care providers, and implementing telehealth systems are some of the most urgent interventions that need to be established in the future.
RESUMO
INTRODUCTION: The most studied anticancer restrictive diets include fasting, fasting-mimicking diets (FMDs) and ketogenic diets (KDs). Besides the current lack of established clinical benefit and the significant risk of malnutrition and micronutrient deficiencies, dietary restrictions in cancer patients might have relevant psychological effects. MATERIALS AND METHODS: We reviewed the randomized and non-randomized controlled clinical trials (CCTs) reporting data on the psychological impact of fasting, FMDs and KDs in cancer patients. We excluded trials on restrictive diets performed for weight reduction in obese or overweight patients, studies on dietary restrictions lasting less than 24 h, and studies on fasting related to cultural or religious beliefs. RESULTS: Three CCTs on fasting or FMDs and eight CCTs on KDs in cancer patients were included. In terms of diet-related distress, emotional, social, and family well-being, none of these studies showed a detrimental impact of fasting, FMDs and KDs. However, clinical trials specifically assessing the psychological aspects in the long term are lacking. CONCLUSIONS AND PERSPECTIVES: In the absence of a conclusive evidence on the clinical benefits of restrictive diets, which carry significant risks especially if unsupervised, further studies are needed to clarify their psychological impact in cancer patients. Multidisciplinary approaches including psychological evaluations should be used to ameliorate patient selection for clinical trials, identify early distress symptoms, and increase patient compliance to dietary recommendations.

Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for patients with limited-stage muscle-invasive bladder cancer. RC is associated with a complication rate of approximately 50-88%. Immunonutrition (IMN) refers to the administration of substrates, such as omega-3 fatty acids, arginine, glutamine, and nucleotides, that modulate the immune response. IMN has been associated with improved outcomes following surgery for esophagogastric, colorectal and pancreatic cancer. In this paper, we describe a study protocol for a multicentre, randomised, open-label clinical trial to evaluate the effect of IMN in patients undergoing RC for bladder cancer. A 7-day preoperative course of IMN is compared with a standard high-calorie high-protein oral nutritional supplement. The primary outcome of this study is the rate of complications (infectious, wound-related, gastrointestinal, and urinary complications) in the first 30 days after RC. Secondary outcomes include time to recovery of bowel function and postoperative mobilisation, changes in muscle strength and body weight, biochemical modifications, need for blood transfusion, length of stay, readmission rate, and mortality. The results of this study may provide new insights into the impact of IMN on postoperative outcomes after RC and may help improve IMN prescribing based on patient nutritional status parameters.

BACKGROUND: We investigated the role of infectious disease consultation (IDC) on therapeutic appropriateness in Gram-negative bloodstream infections (GNBSIs) in a setting with a high proportion of antibiotic resistance. Secondary outcomes were in-hospital mortality and the impact of rapid diagnostic tests (RDTs). METHODS: Retrospective study on hospitalised patients with GNBSIs. Therapy was deemed appropriate if it had the narrowest spectrum considering infection and patients' characteristics. Interventional-IDC (I-IDC) group included patients with IDC-advised first appropriate or last non-appropriate therapy. Time to first appropriate therapy and survival were evaluated by Kaplan-Meier curves. Factors associated with therapy appropriateness were assessed by multivariate Cox proportional-hazard models. RESULTS: 471 patients were included. High antibiotic resistance rates were detected: quinolones 45.5%, third-generation cephalosporins 37.4%, carbapenems 7.9%. I-IDC was performed in 31.6% of patients (149/471), RDTs in 70.7% (333/471). The 7-day probability of appropriate treatment was 91.9% (95% confidence interval [95%CI]: 86.4-95.8%) vs. 75.8% (95%CI: 70.9-80.4%) with and without I-IDC, respectively (p-value = 0.0495); 85.5% (95%CI: 81.3-89.1%) vs. 69.4% (95%CI: 61.3-77.2%) with and without RDTs, respectively (p-value = 0.0023). Compared to RDTs alone, the combination with I-IDC was associated with a higher proportion of appropriate therapies at day 7: 81.9% (95%CI: 76.4-86.7%) vs. 92.6% (95%CI: 86.3-96.7%). At multivariate analysis, I-IDC and RDTs were associated with time to first appropriate therapy [adjusted hazard-ratio 1.292 (95%CI: 1.014-1.647) and 1.383 (95%CI: 1.080-1.771), respectively], with no impact on mortality. CONCLUSIONS: In a setting with a high proportion of antibiotic resistance, IDC and RDTs were associated with earlier prescription of appropriate therapy in GNBSIs, without impact on mortality.

Preoperative nutritional status is a pivotal aspect to consider in patients with cancer undergoing radical cystectomy (RC), as those at risk of malnutrition or already malnourished are more prone to post-surgical complications. The loss of muscle mass is a major consequence of cancer-related malnutrition. It is associated with increased risk of hospital readmission, longer hospitalization, and higher mortality. Nowadays, the close relationship between nutritional and immunological aspects under stressful conditions, such as surgery, represents an emerging scientific and clinical issue. Indeed, the synergistic action of reduced food intake and systemic inflammation generates metabolic derangements with tissue catabolism, including skeletal muscle breakdown, which is, in turn, associated with immune system dysfunction. In order to offer an additional immune-nutritional boost to the post-surgical phase, particularly in malnourished patients, nutritional support may include oral nutritional supplements and/or enteral formulas enriched with specific nutrients such as omega-3 fatty acids, arginine, glutamine, and nucleotides, with acknowledged immune-modulating effects. In the present narrative review, we addressed the state of the art of the available scientific literature on the benefit of immunonutrition in patients undergoing RC for cancer and suggest possible future perspectives to be explored. Although the role of immunonutrition was found to be little explored in the context of urologic oncology, the preliminary available data on radical cystectomy, summarized in the present paper, are promising and suggest that it may improve postoperative outcomes through immunomodulation, regardless of nutritional status before surgery.
RESUMO
BACKGROUND: Malnutrition is a frequent problem in oncology and is associated with reduced response to cancer treatments, increased drug-related toxicity, higher rates of clinical complications, reduced quality of life (QoL) and worse prognosis. Guidelines on clinical nutrition in oncology emphasise the usefulness of early assessment of nutritional status for a prompt identification of malnutrition and the implementation of effective interventions, but no real-world clinical data are available on the adequate management of nutritional support in patients with cancer in Italy. METHODS AND ANALYSIS: This is an observational, longitudinal, multicentre registry of patients with a new diagnosis of cancer or metastatic disease, candidates for active treatment. They will be identified in at least 15 Italian oncological centres, members of the Alliance Against Cancer Working Group 'Survivorship Care and Nutritional Support'. At least 1500 patients with cancer are expected to be enrolled each year. Detailed clinical and nutritional data will be collected by oncologists and clinical nutritionists during the visits foreseen in the clinical practice, through an ad hoc developed digital platform (e-Nutracare). The effects of malnutrition and nutritional support-at diagnosis and during follow-up-on overall survival and progression-free survival, as well as on patients' symptoms and QoL, will be investigated. ETHICS AND DISSEMINATION: The study protocol was approved by the Ethics Committee of the Fondazione IRCCS Policlinico San Matteo, Pavia, Italy and from the Ethics Committees of all other participating centres. An informed consent will be obtained from each patient enrolled in the study. Study findings will be disseminated through peer-reviewed journals, conferences and patients with cancer or professional associations. The registry will allow a better monitoring of the nutritional status of patients with cancer, promoting adequate and sustainable nutritional support, with the ultimate goal of improving the care and prognosis of these patients.

BACKGROUND: COVID-19 patients frequently develop respiratory failure requiring mechanical ventilation. Data on long-term survival of patients who had severe COVID-19 are insufficient. We assessed and compared two-year survival, CT imaging, quality of life, and functional recovery of COVID-19 ARDS patients requiring respiratory support with invasive (IMV) versus noninvasive ventilation (NIV). METHODS: Patients with COVID-19 pneumonia admitted up to May 28th, 2020, who required IMV or NIV, and survived to hospital discharge were enrolled. Patients were contacted two years after discharge to assess vital status, functional, psychological, and cognitive outcomes using validated scales. Patients with persistent respiratory symptoms or high burden of residual lung damage at previous CT scan received a two-year chest CT scan. RESULTS: Out of 61 IMV survivors, 98% were alive at two-year follow-up, and 52 completed the questionnaire. Out of 82 survivors receiving NIV only, 94% were alive at two years, and 47 completed the questionnaire. We found no major differences between invasively and noninvasively ventilated patients, with overall acceptable functional recovery. Among the 99 patients completing the questionnaire, 23 have more than moderate exertional dyspnea. Chest CT scans showed that 4 patients (all received IMV) had fibrotic-like changes. CONCLUSIONS: Patients who received mechanical ventilation due to COVID-19 and were discharged from hospital had a 96% survival rate at the two-year follow-up. There was no difference in overall recovery and quality of life between patients who did and did not require IMV, although respiratory morbidity remains high.

Depression and selective serotonin reuptake inhibitors (SSRI) reduce bone mass and increase fracture risk. We analyzed the association between SSRI use and fractures development in nursing homes residents during a one-year prospective observational study. Sixty-four of the 800 participants developed a fracture during the one-year follow-up. Individuals who developed fractures used SSRIs more often than residents who did not (40.6% vs 28.7%, p =0.045). SSRIs were associated with fractures (adjusted OR 1.76, 95% CI 1.04 - 2.98, p = 0.036). A regular medication review should be performed to reduce inappropriate prescriptions and related adverse consequences.

PURPOSE: Systemic inflammation has been associated with corrected QT (QTc) interval prolongation. The role of inflammation on QTc prolongation in COVID-19 patients was investigated. METHODS: Patients with a laboratory-confirmed SARS-CoV-2 infection admitted to IRCCS San Raffaele Scientific Institute (Milan, Italy) between March 14, 2020, and March 30, 2020 were included. QTc-I was defined as the QTc interval by Bazett formula in the first ECG performed during the hospitalization, before any new drug treatment; QTc-II was the QTc in the ECG performed after the initiation of hydroxychloroquine drug treatment. RESULTS: QTc-I was long in 45 patients (45%) and normal in 55 patients (55%). Patients with long QTc-I were older and more frequently males. C-Reactive protein (CRP) and white blood cell (WBC) count at hospitalization were higher in patients with long QTc-I and long QTc-II. QTc-I was significantly correlated with CRP levels at hospitalization. After a median follow-up of 83 days, 14 patients (14%) died. There were no deaths attributed to ventricular arrhythmias. Patients with long QTc-I and long QTc-II had a shorter survival, compared with normal QTc-I and QTc-II patients, respectively. In Cox multivariate analysis, independent predictors of mortality were age (HR = 1.1, CI 95% 1.04-1.18, p = 0.002) and CRP at ECG II (HR 1.1, CI 95% 1.0-1.1, p = 0.02). CONCLUSIONS: QTc at hospitalization is a simple risk marker of mortality risk in COVID-19 patients and reflects the myocardial inflammatory status.

BACKGROUND & AIMS: Sarcopenia, a loss of muscle mass, quality and function, which is particularly evident in respiratory muscles, has been associated with many clinical adverse outcomes. In this study, we aimed at evaluating the role of reduced muscle mass and quality in predicting ventilation weaning, complications, length of intensive care unit (ICU) and of hospital stay and mortality in patients admitted to ICU for SARS-CoV-2-related pneumonia. METHODS: This was an observational study based on a review of medical records of all adult patients admitted to the ICU of a tertiary hospital in Milan and intubated for SARS-CoV-2-related pneumonia during the first wave of the COVID-19 pandemic. Muscle mass and quality measurement were retrieved from routine thoracic CT scans, when sections passing through the first, second or third lumbar vertebra were available. RESULTS: A total of 81 patients were enrolled. Muscle mass was associated with successful extubation (OR 1.02, 95% C.I. 1.00-1.03, p = 0.017), shorter ICU stay (OR 0.97, 95% C.I. 0.95-0.99, p = 0.03) and decreased hospital mortality (HR 0.98, 95% C.I. 0.96-0.99, p = 0.02). Muscle density was associated with successful extubation (OR 1.07, 95% C.I. 1.01-1.14; p = 0.02) and had an inverse association with the number of complications in ICU (Β -0.07, 95% C.I. -0.13 - -0.002, p = 0.03), length of hospitalization (Β -1.36, 95% C.I. -2.21 - -0.51, p = 0.002) and in-hospital mortality (HR 0.88, 95% C.I. 0.78-0.99, p = 0.046). CONCLUSIONS: Leveraging routine CT imaging to measure muscle mass and quality might constitute a simple, inexpensive and powerful tool to predict survival and disease course in patients with COVID-19. Preserving muscle mass during hospitalisation might have an adjuvant role in facilitating remission from COVID-19.

Background: This study's primary aim was to evaluate the impact of thrombotic complications on the development of secondary infections. The secondary aim was to compare the etiology of secondary infections in patients with and without thrombotic complications. Methods: This was a cohort study (NCT04318366) of coronavirus disease 2019 (COVID-19) patients hospitalized at IRCCS San Raffaele Hospital between February 25 and June 30, 2020. Incidence rates (IRs) were calculated by univariable Poisson regression as the number of cases per 1000 person-days of follow-up (PDFU) with 95% confidence intervals. The cumulative incidence functions of secondary infections according to thrombotic complications were compared with Gray's method accounting for competing risk of death. A multivariable Fine-Gray model was applied to assess factors associated with risk of secondary infections. Results: Overall, 109/904 patients had 176 secondary infections (IR, 10.0; 95% CI, 8.8-11.5; per 1000-PDFU). The IRs of secondary infections among patients with or without thrombotic complications were 15.0 (95% CI, 10.7-21.0) and 9.3 (95% CI, 7.9-11.0) per 1000-PDFU, respectively (P = .017). At multivariable analysis, thrombotic complications were associated with the development of secondary infections (subdistribution hazard ratio, 1.788; 95% CI, 1.018-3.140; P = .043). The etiology of secondary infections was similar in patients with and without thrombotic complications. Conclusions: In patients with COVID-19, thrombotic complications were associated with a high risk of secondary infections.
RESUMO
BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-related disease (COVID-19) is an infectious disease characterized by systemic inflammation, which might enhance baseline thrombotic risk, especially in hospitalized patients. Little is, however, known about predictors of thrombotic complications in patients with COVID-19. METHODS: We prospectively followed up 180 hospitalized COVID-19 patients. Demographics, clinical and laboratory features at presentation and past medical history were tested as predictors of the first thrombotic complication through multivariate Cox regression analysis and a categorical score generated based on the results. RESULTS: Sixty-four thromboses were recorded in 54 patients, of whom seven with thrombosis on admission and 47 with thrombosis during hospitalization. Patients with thrombosis were mainly Caucasian and diabetic, had marked baseline signs of inflammation and organ damage, lower PaO

BACKGROUND: Non-invasive mechanical ventilation (NIV) is effective for symptom relief and respiratory support in patients with respiratory insufficiency, severe comorbidities and no indication to intubation. Experience with NIV as the ceiling of treatment in severely compromised novel coronavirus disease (COVID-19) patients is lacking. METHODS: We evaluated 159 patients with COVID-19-related acute respiratory syndrome (ARDS), 38 of whom with NIV as the ceiling of treatment, admitted to an ordinary ward and treated with continuous positive airway pressure (CPAP) and respiratory physiotherapy. Treatment failure and death were correlated with clinical and laboratory parameters in the whole cohort and in patients with NIV as the ceiling of treatment. RESULTS: Patients who had NIV as the ceiling of treatment were elderly, with a low BMI and a high burden of comorbidities, showed clinical and laboratory signs of multiorgan insufficiency on admission and of rapidly deteriorating vital signs during the first week of treatment. NIV failure occurred overall in 77 (48%) patients, and 27/38 patients with NIV as the ceiling of treatment died. Congestive heart failure, chronic benign hematological diseases and inability/refusal to receive respiratory physiotherapy were independently associated to NIV failure and mortality. Need for increased positive end-expiratory pressures and low platelets were associated with NIV failure. Death was associated to cerebrovascular disease, need for CPAP cycles longer than 12 h and, in the subgroup of patients with NIV as the ceiling of treatment, was heralded by vital sign deterioration within 48 h. CONCLUSIONS: NIV and physiotherapy are a viable treatment option for patients with severe COVID-19 and severe comorbidities.

PURPOSE: Individuals with diabetes/stress hyperglycemia carry an increased risk for adverse clinical outcome in case of SARS-CoV-2 infection. The purpose of this study was to evaluate whether this risk is, at least in part, modulated by an increase of thromboembolic complications. METHODS: We prospectively followed 180 hospitalized patients with confirmed COVID-19 pneumonia admitted to the Internal Medicine Units of San Raffaele Hospital. Data from 11 out of 180 patients were considered incomplete and excluded from the analysis. We analysed inflammation, tissue damage biomarkers, hemostatic parameters, thrombotic events (TEs) and clinical outcome according to the presence of diabetes/stress hyperglycemia. RESULTS: Among 169 patients, 51 (30.2%) had diabetes/stress hyperglycemia. Diabetes/stress hyperglycemia and fasting blood glucose (FBG) were associated with increased inflammation and tissue damage circulating markers, higher D-dimer levels, increased prothrombin time and lower antithrombin III activity. Forty-eight venous and 10 arterial TEs were identified in 49 (29%) patients. Diabetes/stress hyperglycemia (HR 2.71, pâ¯=â¯0.001), fasting blood glucose (HR 4.32, pâ¯<â¯0.001) and glucose variability (HR 1.6, pâ¯<â¯0.009) were all associated with an increased risk of thromboembolic complication. TEs significantly increased the risk for an adverse clinical outcome only in the presence of diabetes/stress hyperglycemia (HR 3.05, pâ¯=â¯0.010) or fasting blood glucose ≥7â¯mmol/L (HR 3.07, pâ¯=â¯0.015). CONCLUSIONS: Thromboembolism risk is higher among patients with diabetes/stress hyperglycemia and COVID-19 pneumonia and is associated to poor clinical outcome. In case of SARS-Cov-2 infection patients with diabetes/stress hyperglycemia could be considered for a more intensive prophylactic anticoagulation regimen.

Bevacizumab added to chemotherapy has shown encouraging efficacy in the neoadjuvant therapy of colorectal cancer liver metastases. In absence of biological predictor factors of efficacy to bevacizumab-based treatment, the assessment of response may be a crucial point to select patients who may benefit the most from surgery. At the same time the pathological response after liver resection could represent a guide for the next therapeutic plan. In the pre-surgical phase, conventional computed tomography and response evaluation with RECIST criteria may underestimate the response to anti-angiogenic drugs. Modified computed tomography criteria of response, morphologic changes as well as novel imaging techniques and metabolic assessment by fluorodeoxyglucose positron emission tomography seem to be promising methods for the assessment of response and for leading the clinical choices. Pathological response at the time of surgery is an important prognostic factor and a surrogate of survival for resected patients. Different classification criteria to assess pathological response have been developed, residual viable tumor, tumor regression grade (TRG), modified TRG and tumor thickness at the tumor-normal interface, but to date a superiority of one approach over the others has not been clearly established. In this review, we evaluate the available data with the aim to help the clinicians in the pre- and post-surgical care of patient with colorectal cancer liver metastases treated with bevacizumab-based neoadjuvant strategy.

Currently, therapeutic management of gastric cancer is mainly based on clinical data and histological features. Although several new treatment options have recently been introduced, inter-individual variability of response and drug resistance are still a challenge. Many promising markers have been identified to predict prognosis and likelihood of response to therapy, in order to tailor treatment regimens on the basis of patients' individual features. However, despite recent developments in gene sequencing and molecular diagnostics, many biomarkers still have a controversial role. Published data are often contradictory and at the moment, no molecular marker, other than Human epidermal growth factor receptor-2 (HER2) status for trastuzumab-based treatment, has entered the mainstream of clinical practice. The primary obstacle to the identification of reliable markers lies in technical difficulties in quantitatively assessing molecular alterations; genome-wide analyses are also often misleading due to the complexity of biological processes. Nevertheless, many biomarkers are being evaluated in clinical trials in order to identify criteria for stratifying patients and establish customized therapeutic approaches. In this review, we provide an update on promising biological prognostic and predictive markers, with a focus on growth factor signalling molecules, DNA repair systems, fluoropyrimidine metabolism and apoptotic pathways.
