Correlation between polymorphism of TYMS gene and toxicity response to treatment with 5-fluoruracil and capecitabine.

Tumorigenesis is a multiphasic process in which genetic alterations guide the progressive transformation in cancer cells1. In order to evaluate the possible correlation between some gene variants and the risk of the toxicity development onset, two of the polymorphisms of the thymidylate synthase (TYMS), rs34743033 (2R/3R) and rs16430 (DEL/INS) were investigated. We enrolled in our study 47 patients from the Hospital of Sicily. Our preliminary findings suggest that there could be a linkage between the genotypes discussed and the development of the toxicity following the chemotherapy treatment. These results need to be confirmed by further studies, however this short paper offers some initial insight into the relationships between genetic background and the better outcome for patients.

One shot NEPA plus dexamethasone to prevent multiple-day chemotherapy in sarcoma patients.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) is one of the most feared and disturbing adverse events of cancer treatment associated with decreased adherence to effective chemotherapy regimens. For high-risk soft tissue sarcoma patients, receiving multiple-day chemotherapy (MD-CT), antiemetic guidelines recommend a combination of an NK1 receptor antagonist (NK1-RA), a 5-HT3 receptor antagonist (5HT3-RA), and dexamethasone on each day of the antineoplastic treatment. NEPA is the first oral fixed-dose combination of a highly selective NK1-RA, netupitant, and second-generation 5HT3-RA, palonosetron. So far, no data has been published in literature about the efficacy of a single dose of NEPA in MD-CT. METHODS: We performed a prospective, non-comparative study to assess the efficacy of one shot of NEPA plus dexamethasone in sarcoma patients receiving MD-CT. The primary efficacy endpoint was a complete response (CR: no emesis, no rescue medication) during the overall phase (0-120 h) in cycle 1. The main secondary endpoints were CR during the overall phase of cycles 2 and 3. RESULTS: The primary endpoint was reached in 88.9% of patients. Cycles 2 and 3 overall CR rates were 88.9% and 82.4%, respectively. The antiemetic regimen was well tolerated. CONCLUSIONS: This pilot study showed the benefit of one shot of NEPA to prevent CINV in sarcoma patients receiving MD-chemotherapy.

Immuno-targeted combinations in oncogene-addicted non-small cell lung cancer.

The identification of tumor "oncogenic drivers" and the subsequent development of targeted therapy represented a milestone in the treatment of lung cancer over the last years. Tumor genotyping has been incorporated into therapeutic decision making of advanced non-small cell lung cancer (NSCLC) since has become clear that individuals with actionable molecular alterations receiving a matched targeted agent certainly live longer and better. The recent understanding of biological mechanisms underlying cancer immune evasion has allowed the development of a new class of immunomodulatory agents which are able to reactivate host immune-response, offering the potential for long-term disease control and survival in a significant subgroup of lung cancer patients. The complementary therapeutic effects of these two different approaches suggested intriguing potential for therapeutic synergy with combination strategies. Indeed, immunotherapy could consolidate the dramatic but transient tumor responses achieved with targeted therapy into long-term survival benefit, due to the induction of specific anti-tumor memory. However, the great emphasis and expectations linked to immune-targeted combinations have been mostly disappointed by the initial controversial results of early-phase trials, raising relevant concerns about the use of these combinations for lung cancer treatment. This review briefly summarizes the basis of immunogenicity and immune escape in oncogene addicted NSCLC, providing an updated overview of clinical trials, with the final aim of defining the current unmet needs of immuno-targeted combinations in clinical practice.
