Diabetes management in cancer patients. An Italian Association of Medical Oncology, Italian Association of Medical Diabetologists, Italian Society of Diabetology, Italian Society of Endocrinology and Italian Society of Pharmacology multidisciplinary consensus position paper

Cancer management has significantly evolved in recent years, focusing on a multidisciplinary team approach to provide the best possible patient care and address the various comorbidities, toxicities, and complications that may arise during the patient's treatment journey. The co-occurrence of diabetes and cancer presents a significant challenge for health care professionals worldwide. Management of these conditions requires a holistic approach to improve patients' overall health, treatment outcomes, and quality of life, preventing diabetes complications and cancer treatment side-effects. In this article, a multidisciplinary panel of experts from different Italian scientific societies provide a critical overview of the co-management of cancer and diabetes, with an increasing focus on identifying a novel specialty field, 'diabeto-oncology', and suggest new co-management models of cancer patients with diabetes to improve their care. To better support cancer patients with diabetes and ensure high levels of coordinated care between oncologists and diabetologists, 'diabeto-oncology' could represent a new specialized field that combines specific expertise, skills, and training.

MiRNA dysregulation underlying common pathways in type 2 diabetes and cancer development: an Italian Association of Medical Oncology (AIOM)/Italian Association of Medical Diabetologists (AMD)/Italian Society of Diabetology (SID)/Italian Society of Endocrinology (SIE)/Italian Society of Pharmacology (SIF) multidisciplinary critical view

Increasing evidence suggests that patients with diabetes, particularly type 2 diabetes (T2D), are characterized by an increased risk of developing different types of cancer, so cancer could be proposed as a new T2D-related complication. On the other hand, cancer may also increase the risk of developing new-onset diabetes, mainly caused by anticancer therapies. Hyperinsulinemia, hyperglycemia, and chronic inflammation typical of T2D could represent possible mechanisms involved in cancer development in diabetic patients. MicroRNAs (miRNAs) are a subset of non-coding RNAs, ⁓22 nucleotides in length, which control the post-transcriptional regulation of gene expression through both translational repression and messenger RNA degradation. Of note, miRNAs have multiple target genes and alteration of their expression has been reported in multiple diseases, including T2D and cancer. Accordingly, specific miRNA-regulated pathways are involved in the pathogenesis of both conditions. In this review, a panel of experts from the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE), and Italian Society of Pharmacology (SIF) provide a critical view of the evidence about the involvement of miRNAs in the pathophysiology of both T2D and cancer, trying to identify the shared miRNA signature and pathways able to explain the strong correlation between the two conditions, as well as to envision new common pharmacological approaches.

The changing scenario of 1st line therapy in non-oncogene addicted NSCLCs in the era of immunotherapy

During the last two decades front-line treatment of metastatic Non Small Cell Lung Cancer (NSCLC) has profoundly changed moving from the old "one size fits all" concept to a "histology-based" approach and then, for a small subgroup of patients to a "molecularly-selected" one. The development of immune checkpoint inhibitors and the unprecedented results reported in 2^nd/3^rd line prompted the evaluation of these novel therapeutic agents in chemotherapy-naïve patients either alone or in combination with platinum-based chemotherapy. Several randomized trials are evaluating the impact of immune-checkpoint inhibitors in 1^st line and some of them have yet produced preliminary evidence of efficacy. However, still a long way to go and several questions are still unanswered, including proper patients selection, optimal sequential/combinatorial use of these agents, appropriate treatment duration, and finally the identification of predictive biomarkers. The aim of this paper is to provide a comprehensive overview on the growing role of immune checkpoint inhibitors in the upfront treatment of advanced non-oncogene addicted NSCLC either as single agent or in combination with other agents.

Third generation EGFR TKIs in EGFR-mutated NSCLC: Where are we now and where are we going

The therapeutic landscape of Non Small Lung Cancer (NSCLC) has been profoundly changed over the last decade with the clinical introduction of Epidermal Growth Factor Receptor (EGFR) tyrosine kinase inhibitors (TKIs) and the discovery of EGFR activating mutations as the major predictive factor to these agents. Despite impressive clinical activity against EGFR-mutated NSCLCs, the benefit seen with 1st and 2nd generation EGFR TKIs is usually transient and virtually all patients become resistant. Several different mechanisms of acquired resistance have been reported to date, but the vast majority of patients develop a secondary exon 20 mutation in the ATP-binding site of EGFR, namely T790M. The discovery of mutant-selective EGFR TKIs that selectively inhibit EGFR-mutants, including T790M-harboring NSCLCs, while sparing EGFR wild type, provide the opportunity for overcoming the major mechanism of acquired resistance to 1st and 2nd generation EGFR TKIs, with a relatively favorable toxicity profile. The development of this novel class of EGFR inhibitors poses novel challenges in the rapidly evolving therapeutic paradigm of EGFR-mutated NSCLCs and the next few years will witness the beginning of a new era for EGFR inhibition in lung cancer. The aim of this paper is to provide a comprehensive overview of the increasing body of data emerging from the ongoing clinical trials with this promising novel therapeutic class of EGFR inhibitors.

Pegylated liposomal doxorubicin in combination with gemcitabine in elderly women with locally advanced or metastatic breast cancer: Safety and activity results of our clinical experience

e12005

Background: Elderly breast cancer patients have an increased risk of toxicity from chemotherapy, especially from anthracycline-based regimens. Pegylated liposomal doxorubicin (PLD) has shown a better tolerability profile also in combination with gemcitabine (GEM), as evidenced in several phase II trials. The aim of this study is to retrospectively evaluate the safety and activity of this combination in chemo-naïve or pre-treated elderly patients with advanced breast cancer. Methods: From January 2006 to March 2008, 39 patients (pts) with age ≥ 65 received, at our institution, PLD 25 mg/m2 (day 1, q21) and GEM 800 mg/m2 (days 1 and 8, q21). Median age was 72 (range, 65–79). ECOG PS was 0/1/2 in 14/23/2 pts, respectively. 12 pts (31%) were chemo-naïve, 20 (51%) received prior adjuvant anthracycline-based regimens, and 7 (18%) received other chemotherapies. PLD-GEM combination was administered as first line in 35 pts (90%). Median left ventricular ejection fraction (LVEF) at baseline was 61% (range, 50%-75%). 28 patients (72%) had metastatic disease: 10 in liver, 6 in lung, 2 in skin, and 10 in multiple sites. Estrogen receptor was positive in 32 pts (82%); HER-2+ in 5 pts; 7 pts were triple negative. Results: A total of 206 cycles were administered with a mean number of cycles per patient of 5.2 (range, 3–12). Grade 3–4 neutropenia occurred in 4 (10%) and 3 patients (8%), respectively; grade 3 anemia in two pts (5%). Non-hematological toxicity was mild, with 5 cases (13%) of grade 3 mucositis, and 2 cases (5%) of grade 2 palmar-plantar erythrodysesthesia syndrome. No modifications in LVEF or toxic deaths were documented. We observed 1 CR (2.5%) and 11 PR (28.2%). Eighteen (44%) patients experienced SD for 16 weeks and an overall clinical benefit of 76.8%. Conclusions: The combination of PLD and GEM has a favorable tolerability and a safety profile with an evident clinical benefit and should represent an interesting treatment option in elderly women with advanced breast cancer.

Safety and activity of trastuzumab-containing therapies for the treatment of metastatic breast cancer: our long-term clinical experience (GOIM study)

BACKGROUND

Trastuzumab is widely used as the treatment of choice for HER2-positive metastatic breast cancer (MBC).

PATIENTS AND METHODS

Seventy patients, median age 57 years and range 31-81 years, were included in our retrospective analysis with the aim to evaluate safety and activity of trastuzumab-containing therapies.

RESULTS

We observed for first-line treatment response rate (RR) 41%, stable disease (SD) 47% and time to progression (TTP) 8 months (range 1-44). Corresponding numbers for second line were RR 23%, SD 62% and (TTP) 9 months (range 3-23) and beyond second line RR 22%, SD 78% and (TTP) 9 months (range 4-19). Overall survival was 19.2 months (3-62 months). The median cumulative dose of trastuzumab administrated was 5286 mg (464-17 940 mg). Trastuzumab was well tolerated. Median left ventricular ejection function (LVEF) at baseline was 62% and at the end of treatment was 59%. The more relevant adverse events consisted of an asymptomatic decrease in LVEF to 40% (baseline 60%) and a grade 3 symptomatic increase in bilirubin.

CONCLUSION

Trastuzumab-containing therapies in MBC show a good safety and toxicity profile and a remarkable activity even in heavily pretreated women. Patients should benefit from continued trastuzumab therapy, as shown by the maintenance of (TTP) even beyond second-line treatment.
