Pharmacokinetic and metabolism determinants of fluoropyrimidines and oxaliplatin activity in treatment of colorectal patients
2011
Fluoropyrimidines and oxaliplatin continued to be the mainstay of therapeutic regimens in the treatment of colorectal cancer (CRC). For this reason, pharmacokinetic and metabolism of these drugs were analyzed and the identification of accurate and validated predictive, prognostic and toxicity markers became necessary to develop an effective therapy adapted to the patient's molecular profile, while minimizing life-threatening toxicities. In this review, we discuss literature data, defining predictive and prognostic markers actually identified in the treatment of CRC. We analyzed predictive markers of fluoropyrimidines effectiveness, principally for 5-Fluorouracil (5-FU) and also for oral flu…
Experimental techniques for testing the sensitivity of bladder tumours to antineoplastic drugs
1973
A number of laboratory tests can be employed to examine the sensitivity of human bladder tumour cells to various chemotherapeutic agents.-Their principles and methods, and some preliminary results, are described with special reference to certain in vitro and in vivo cytotoxicity tests and to heterotransplantation in the hamster. Satisfactory agreement has sometimes been observed between experimental results and clinical responses, but our experience is still very limited.-The employment of several such tests would probably lead to a greater degree of reliability in the laboratory assessment of the sensitivity of bladder tumours to cytotoxic drugs.
Redox imbalances in ageing and metabolic alterations: Implications in cancer and cardiac diseases. An overview from the working group of cardiotoxici…
2020
Metabolic syndrome (MetS) is a well established risk factor for cardiovascular (CV) diseases. In addition, several studies indicate that MetS correlates with the increased risk of cancer in adults. The mechanisms linking MetS and cancer are not fully understood. Several risk factors involved in MetS are also cancer risk factors, such as the consumption of high calorie-food or high fat intake, low fibre intake, and sedentary lifestyle. Other common aspects of both cancer and MetS are oxidative stress and inflammation. In addition, some anticancer treatments can induce cardiotoxicity, including, for instance, left ventricular (LV) dysfunction and heart failure (HF), endothelial dysfunction an…
Isolated Nodal TBC Reactivation in a Patient with Post-Thrombocythemia Myelofibrosis Treated with Ruxolitinib: Case Report and Review of the Literatu…
2021
Ruxolitinib side effects include the most frequent hematological toxicity along with a more recently evidenced immunosuppressive activity, interfering both with the innate and adaptive immunity, and several cases of reactivation of latent infections by opportunistic agents in patients in treatment with ruxolitinib have been published in the last years. Several pathophysiological mechanisms may explain an association between ruxolitinib and opportunistic infections. From what we know, the only case of an isolated lymph node TBC reactivation in a ruxolitinib-treated myelofibrosis (MF) patient was reported by Patil et al. in 2016 [Int J Med Sci Public Health. 2017;6(3):1]. Other 10 cases descr…
S-Adenosylmethionine Supplementation May Reduce Cancer-Related Fatigue: A Prospective Evaluation Using the FACIT-F Questionnaire in Colon Cancer Pati…
2021
<b><i>Background:</i></b> Fatigue is a common distressing symptom for patients living with chronic or acute diseases, including liver disorders and cancer (<i>Cancer-Related Fatigue</i>, 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…
MTHFR and VDR Polymorphisms Improve the Prognostic Value of MYCN Status on Overall Survival in Neuroblastoma Patients
2020
Single nucleotide polymorphisms (SNPs) in Pharmacogenetics can play an important role in the outcomes of the chemotherapy treatment in Neuroblastoma, helping doctors maximize efficacy and minimize toxicity. Employing AgenaBioscience MassArray, 96 SNPs were genotyped in 95 patients looking for associations of SNP with response to induction therapy (RIT) and grade 3&ndash
Weekly docetaxel in the treatment of metastatic breast cancer
2008
Breast cancer is the most frequent tumor among women worldwide and is the second cause of cancer-related mortality in the US. Metastatic breast cancer (MBC) accounts for less than 10% of newly diagnosed breast cancer patients and about 30% of early breast cancer patients will develop recurrent, advanced, or metastatic disease. It remains an incurable illness and the primary goal of its management is palliative. Several agents are active for the fi rst-line treatment of MBC. The taxanes, paclitaxel and docetaxel, represent the standard of care for the treatment of these patients. Among the various schedules, docetaxel can be administered weekly, achieving similar effi cacy results with lower…
Oral vinorelbine and capecitabine as first-line therapy in metastatic breast cancer: a retrospective analysis
2021
A retrospective analysis of 70 patients with triple-negative or hormone-resistant advanced breast carcinoma who had not previously received chemotherapy was carried out. Patients received oral vinorelbine 60 mg/m2 on day 1 and 8, plus capecitabine 1000 mg/m2 bid for 14 consecutive days every 3 weeks. Overall response rate was 53% with a 9% complete response rate. Stable disease was recorded in 27% of the cases. Median progression-free survival was 7.9 months and median overall survival was 29.2 months. Toxicity was generally mild and easily manageable. These data demonstrate that this combination is feasible, safe and active as first-line treatment of triple-negative fully hormone-resistant…
Early diagnosis, clinical management, and follow-up of cardiovascular events with ponatinib
2020
Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by neoplastic transformation of pluripotent cells due to a typical cytogenetic and molecular mutation known as Philadelphia (Ph) chromosome. In 2001, the introduction of the tyrosine kinasis inhibitor (TKI) imatinib as a therapeutic strategy for CML with PH chromosome mutation represented an important step towards treatment of these patients, and nowadays, this drug represents the gold therapeutic standard in this clinical setting. A second generation of TKIs (dasatinib, nilotinib, and bosutinib) showed an effective action in all patients with mutations resistant to imatinib. Ponatinib is a third-generation TKI an…
Intensity modulated radiation therapy with simultaneous integrated boost in early breast cancer irradiation. Report of feasibility and preliminary to…
2015
To investigate the feasibility and tolerance in the use of adjuvant intensity modulated radiation therapy (IMRT) and simultaneous integrated boost in patients with a diagnosis of breast cancer after breast-conserving surgery.Between September 2011 to February 2013, 112 women with a diagnosis of early breast cancer (T1-2, N0-1, M0) were treated with IMRT and simultaneous integrated boost after breast-conserving surgery in our institution. A dose of 50Gy in 25 fractions was prescribed to the whole breast and an additional dose of radiation was prescribed on the tumour bed. A dose prescription of 60Gy in 25 fractions to the tumour bed was used in patients with negative margins after surgery, w…
