Medical Oncology Unit, Università Campus Bio-Medico di Roma, Rome, Italy.

Background: Fatigue is a common distressing symptom for patients living with chronic or acute diseases, including liver disorders and cancer (Cancer-Related Fatigue, CRF). Its etiology is multifactorial, and some hypotheses regarding the pathogenesis are summarized, with possible shared mechanisms both in cancer and in chronic liver diseases. A deal of work has investigated the role of a multifunctional molecule in improving symptoms and outcomes in different liver dysfunctions and associated symptoms, including chronic fatigue: S-adenosylmethionine (SAM; AdoMet). The aim of this work is actually to consider its role also in oncologic settings.

Patients And Methods: Between January 2006 and December 2009, at the University Campus Bio-Medico of Rome, 145 patients affected by colorectal cancer in adjuvant (n = 91) or metastatic (n = 54; n = 40 with liver metastases) setting and treated with oxaliplatin-based regimen (FOLFOX for adjuvant and bevacizumab + XELOX for metastatic ones), 76 of which with the supplementation of S-adenosylmethionine (AdoMet; 400 mg b.i.d.) (57% of adjuvant patients and 44% of metastatic ones) and 69 without AdoMet supplementation, were evaluated for fatigue prevalence using the Functional Assessment of Chronic Illnesses Therapy-Fatigue (FACIT-F) questionnaire, at 3 and 6 months after the beginning of oncologic treatment. Notably, the number of patients with liver metastases was well balanced between the group of patients treated with AdoMet and those who were not.

Results: Among patients receiving oxaliplatin-based chemotherapy, both in adjuvant and in metastatic settings, after just 3 months from the beginning of chemotherapy, mean scores from questionnaire domains like FACIT-F subscale (7.9 vs. 3.1, p = 0.006), FACIT physical (6.25 vs. 3.32, p = 0.020), FACIT emotional (4.65 vs. 2.19, p = 0.045), and FACIT-F total score (16.5 vs. 8.27, p = 0.021) were higher in those receiving supplementation of AdoMet, resulting in reduced fatigue; a significant difference was maintained even after 6 months of treatment.

Discussion And Conclusions: Mechanisms and strategies for managing CRF are not fully understood. This work aimed at investigating the possible role of S-adenosylmethionine supplementation in improving fatigue scores in a specific setting of cancer patients, using a FACIT-F questionnaire, a well-validated quality of life instrument widely used for the assessment of CRF in clinical trials.

Breakthrough Cancer Pain Clinical Features and Differential Opioids Response: A Machine Learning Approach in Patients With Cancer From the IOPS-MS Study.

JCO Precis Oncol 2020 4;4. Epub 2020 Nov 4.

Pain Therapy Unit, "A. Businco" Hospital, ASL 8, Cagliari, Italy.

Purpose: A large proportion of patients with cancer suffer from breakthrough cancer pain (BTcP). Several unmet clinical needs concerning BTcP treatment, such as optimal opioid dosages, are being investigated. In this analysis the hypothesis, we explore with an unsupervised learning algorithm whether distinct subtypes of BTcP exist and whether they can provide new insights into clinical practice.

Methods: Partitioning around a k-medoids algorithm on a large data set of patients with BTcP, previously collected by the Italian Oncologic Pain Survey group, was used to identify possible subgroups of BTcP. Resulting clusters were analyzed in terms of BTcP therapy satisfaction, clinical features, and use of basal pain and rapid-onset opioids. Opioid dosages were converted to a unique scale and the BTcP opioids-to-basal pain opioids ratio was calculated for each patient. We used polynomial logistic regression to catch nonlinear relationships between therapy satisfaction and opioid use.

Results: Our algorithm identified 12 distinct BTcP clusters. Optimal BTcP opioids-to-basal pain opioids ratios differed across the clusters, ranging from 15% to 50%. The majority of clusters were linked to a peculiar association of certain drugs with therapy satisfaction or dissatisfaction. A free online tool was created for new patients' cluster computation to validate these clusters in future studies and provide handy indications for personalized BTcP therapy.

Conclusion: This work proposes a classification for BTcP and identifies subgroups of patients with unique efficacy of different pain medications. This work supports the theory that the optimal dose of BTcP opioids depends on the dose of basal opioids and identifies novel values that are possibly useful for future trials. These results will allow us to target BTcP therapy on the basis of patient characteristics and to define a precision medicine strategy also for supportive care.

Current Treatment Options for HCC: From Pharmacokinetics to Efficacy and Adverse Events in Liver Cirrhosis.

Curr Drug Metab 2020 ;21(11):866-884

Unit of Clinical Medicine and Hepatology, University Campus Bio-Medico, Rome, Italy.

Background: Hepatocellular carcinoma (HCC) is among the world's most common cancers. For over ten years, the only medical treatment for it has been the multikinase inhibitor Sorafenib. Currently, however, other first or second-line therapeutic options have also shown efficacy against HCC, such as multikinase inhibitors (Regorafenib, Lenvatinib, and Cabozantinib), a monoclonal antibody against the vascular endothelial growth factor receptor 2 (Ramucirumab), and immune-checkpoint inhibitors (Nivolumab, Pembrolizumab, Ipilimumab).

Aim: The aim of this paper is to review the metabolic pathways of drugs that have been tested for the treatment of HCC and the potential influence of liver failure over those pathways.

Methods: The Food and Drug Administration (FDA)'s and European Medicines Agency (EMA)'s datasheets, results from clinical trials and observational studies have been reviewed.

Results: This review summarizes the current knowledge regarding targets, metabolic pathways, drug interactions, and adverse events of medical treatments for HCC in cirrhotic patients.

Conclusion: The new scenario of systemic HCC therapy includes more active drugs with different metabolic pathways and different liver adverse events. Clinical and pharmacological studies providing more data on the safety of these molecules are urgently needed.

The Time Course of Pulmonary Function Tests in COPD Patients with Different Levels of Blood Eosinophils.

Biomed Res Int 2016 16;2016:4547953. Epub 2016 Oct 16.

Department of Systems Medicine, University of Rome Tor Vergata, Chair of Respiratory Medicine, Rome, Italy.

Only very few studies have investigated the influence of eosinophils on the functional progression of COPD. We aimed at retrospectively analyzing the trend of pulmonary function tests over time in patients with COPD according to two baseline blood eosinophil cell count strata (<2% [EOS-] and ≥2% [EOS+]). We used the last 9-year data present in the database of our outpatient clinic and selected only those who had two blood counts that would guarantee the stability of the value of eosinophils and serial spirometry for 4 consecutive years. The analysis of the time course of the spirometric variables analysed showed differences in FEV1 and FVC decline between the subjects of the EOS- group and those of the EOS+ group. The integrated evaluation of our results suggests that the different level of blood eosinophils in the two groups may have influenced independently the time course of the pulmonary function tests and identify two subgroups of subjects with specific disease characteristics: the hyperinflator and the rapid decliner, respectively.
