Introduction: Lung cancer is one of the leading cause of cancer death worldwide, with an estimate incidence of about 2 million new cases per year. Among all lung cancers, non-small-cell lung cancer (NSCLC) is the most frequent (nearly 85%) with a 5-year survival of about 25% when all stages are considered.NSCLCs are frequently mutated in KRAS or STK11/LKB1 and co-mutation is often reported. Considering the key role of STK11/LKB1 in controlling cell metabolism, we hypothesized that NSCLC harboring mutations in this gene could be vulnerable to metabolic stresses. Different studies in the last years have highlighted how is possible to interfere with cancer metabolism using metformin and caloric restriction.Our work aimed at investigating the role of metabolic stress in determining response to chemotherapy and immunotherapy in LKB1 mutated NSCLC model. Methods: For isolation of cell lines with the genetic backgrounds, nodules from lungs of KRASG12D/LKB1wt and KRASG12D/LKB1mut transgenic mice were used. Stabilized cell lines were then inoculated intramuscularly in immunocompetent mice and treated with chemotherapy alone (cisplatin) or in combination with metformin and caloric restriction. Caloric restriction consisted of 36 hours of fasting every week for three weeks. Metformin was administered daily for the entire experiment while cisplatin was given once a week for three weeks. Results: We started our in vivo experiments comparing the response of the tumors characterized by the mutation in KRASG12D or the co-mutation KRASG12D/LKB1mut. The results indicate that the addition of metformin and caloric restriction improve the activity of cisplatin in both tumors but a stronger effect was detected in tumors presenting the deletion of LKB1. In fact, only in the latter group, the effect of the combination lasted beyond the end of the treatment slowing down the tumor growth. The different combinations were well tolerated. Molecular analysis on tumor samples run in parallel are in progress. Conclusion: Our in vivo preliminary studies confirm our hypothesis that the addition of the caloric restriction and metformin is able to improve the antitumor activity of the cisplatin without increasing the treatment toxicity in tumors characterized by the co-mutations of KRASG12D/LKB1mut. Further investigations are ongoing on the role of metabolic stress in addition to the immunotherapy (using anti PD-1 antibody as immunocheckpoint inhibitor).

Triplet chemotherapy with fluoropyrimidines, oxaliplatin and irinotecan is a standard therapy for metastatic colorectal cancer (CRC). Single nucleotide polymorphisms (SNPs) in DPYD and UGT1A1 influence fluoropyrimdines and irinotecan adverse events (AEs). Low frequency DPYD variants (c.1905 + 1GA, c.1679 TG, c.2846AT) are validated but more frequent ones (c.496AG, c.1129-5923CG and c.1896 TC) are not. rs895819 TC polymorphism in hsa-mir-27a is associated with reduced DPD activity. In this study, we evaluated the clinical usefulness of a pharmacogenetic panel for patients receiving triplet combinations.Germline DNA was available from 64 CRC patients enrolled between 2008 and 2013 in two phase II trials of capecitabine, oxaliplatin and irinotecan plus bevacizumab or cetuximab. SNPs were determined by Real-Time PCR. We evaluated the functional variants in DPYD (rare: c.1905 + 1GA, c.1679 TG, c.2846AT; most common: c.496AG, c.1129-5923CG, c.1896 TC), hsa-mir-27a (rs895819) and UGT1A1 (*28) genes to assess their association with grade 3-4 AEs.None of the patients carried rare DPYD variants. We found DPYD c.496AG, c.1129-5923CG, c.1896 TC in heterozygosity in 19%, 5% and 8%, respectively, homozygous rs895819 in hsa-mir-27a in 9% and homozygous UGT1A1*28 in 8%. Grade 3-4 AEs were observed in 36% patients and were associated with DPYD c.496AG (odds ratio (OR) 4.93, 95% CI 1.29, 18.87; P = 0.021) and homozygous rs895819 in hsa-mir-27a (OR 11.11, 95% CI 1.21, 102.09; P = 0.020). Carriers of DPYD c.1896 TC and homozygous UGT1A1*28 showed an OR of 8.42 (95% CI 0.88, 80.56; P = 0.052). Multivariate analysis confirmed an independent value for DPYD c.496AG and c.1896 TC.Concomitant assessment of DPYD variants and the UGT1A1*28 allele is a promising strategy needing further validation for dose personalization.
