Myositis/Myasthenia after Pembrolizumab in a Bladder Cancer Patient with an Autoimmunity-Associated HLA: Immune-Biological Evaluation and Case Report.

Pembrolizumab (mAb to PD-1) has been recently approved for the therapy of pretreated urothelial cancer. Despite the efficacy, it is often accompanied by unpredictable and sometime severe immune-related (ir) adverse events (AEs). Here, we report the clinical and immune-biological characterization of a patient with a metastatic bladder cancer who developed myositis signs (M) and a myasthenia-like syndrome (MLS) during treatment with pembrolizumab. The patient presented an autoimmunity-associated HLA haplotype (HLA-A*02/HLA-B*08/HLA-C*07/HLA-DRB1*03) and experienced an increase in activated CD8 T-cells along the treatment. The symptomatology regressed after pembrolizumab discontinuation and a pyridostigmine and steroids-based therapy. This is the first report of concurrent M and MLS appearance in cancer patients receiving pembrolizumab. More efforts are needed to define early the risk and the clinical meaning of irAEs in this setting.

Quality of life and psychological functioning in postmenopausal women undergoing aromatase inhibitor treatment for early breast cancer.

INTRODUCTION: Aromatase inhibitors (AIs) dramatically increased breast cancer (BC) survival, leading to enhanced attention to their long-term consequences on psychological functioning. Conflicting data has been examined regarding the association between AIs administration and the clinical psychological features in BC survivors (BCSs). PURPOSE: As psychological symptoms often occur in such chronic diseases, our study aimed at exploring anxious and depressive symptoms and the perceived quality of life (QoL) in BCSs assessed for osteoporosis. METHODS: The total sample consisted of a clinical sample of 51 outpatient postmenopausal women, diagnosed with BC, and a control group composed of 51 healthy postmenopausal women. All recruited participants were evaluated through the clinical gold standard interview and completed the following self-rating scales: the Hamilton Anxiety Rating Scale, Beck Depression Inventory II edition, and 36-Item Short Form Health Survey, which were administered at baseline and after 6 months in BCSs in AIs treatment, compared with controls. Moreover, all participants were assessed for vitamin D status, bone mineral density (BMD) and subclinical vertebral fractures. Data regarding age, age at menopause, body mass index (BMI), smoking habits and alcohol consumption was collected. RESULTS: BCSs (n = 51) showed higher anxious and depressive symptoms, and lower perceived QoL vs. controls (n = 51) (p<0.05 for all). After 6 months of treatment with AIs, BCSs showed significant reduction of anxious and depressive symptoms and a significantly higher perceived QoL for both physical and mental components, vs. controls. CONCLUSIONS: The improvement of clinical psychological features and perceived QoL was associated with AIs treatment in women being treated with, for early breast cancer. Further studies are needed to obtain a deeper comprehension of the correlation between clinical psychological and physical features in BCSs.

GOLFIG Chemo-Immunotherapy in Metastatic Colorectal Cancer Patients. A Critical Review on a Long-Lasting Follow-Up.

Background: GOLFIG is a chemo-immunotherapy regimen established in preclinical models that combines gemcitabine + FOLFOX (fluoropyrimidine backbone coupled to oxaliplatin) poly-chemotherapy with low-dose s. c. recombinant interleukin-2 (rIL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF). Promising antitumor effects in metastatic colorectal cancer (mCRC) patients were obtained in previous phase II and III trials. Here we report the results of 15 years of follow-up. Methods: This is a multi-institutional retrospective analysis including 179 mCRC patients receiving GOLFIG regimen between June 2002 and June 2018. Sixty-two of them received the treatment as frontline (enrolled in the GOLFIG-2 phase III trial) and 117 as second/third line (49 enrolled in the GOLFIG-1 phase II trial and 68 as compassionate use). One hundred twelve patients showed a primary left side and 67 a primary right side; K/N-ras mutational status was available in 74 cases, and an activating mutation was detected in 33. Kaplan-Meier and Cox regression analyses were carried out to relate PFS and OS with different parameters. Results: Overall, we recorded a mean PFS and OS of 15.28 (95% CI: 10.36-20.20) and 24.6 (95% CI: 19.07-30.14) months, respectively, with 14 patients surviving free of progression for 10 years. This regimen, in our updated survey of the GOLFIG-2 trial, confirmed superiority over FOLFOX in terms of PFS (hazard ratio (HR) = 0.58, p = 0.006) with a trend to a longer OS (HR = 0.69, P = 0.06) in the first line. Our analysis also confirmed significant antitumor activity in pre-treated patients, reporting a mean PFS and OS of 12.55 (95% CI: 7.19-17.9) and 20.28 (95% CI: 14.4-26.13) months, respectively. Immune-related adverse events (irAEs) were recorded in 24% of the cases and were related to a longer survival (HR = 0.36; P = 0.0001). Finally, patients' outcome was not correlated to sex, sidedness, and MT-K/N-ras. Conclusions: The GOLFIG regimen is a reliable underestimated therapeutic option in pre-treated mCRC patients and offers a strong rationale to design further trials.

Bone health assessment by quantitative ultrasound and dual-energy x-ray absorptiometry in postmenopausal women with breast cancer receiving aromatase inhibitors.

OBJECTIVE: Phalangeal quantitative ultrasound (QUS) measurements provide surrogate information on bone quality. The aim of the present study was to assess bone status by phalangeal QUS and by dual-energy x-ray absorptiometry (DXA), and to evaluate bone turnover in breast cancer (BC) women receiving aromatase inhibitors (AIs). METHODS: Sixty postmenopausal BC women and 42 matched controls were recruited (mean age 61.64 ±â€Š8.33 y). Amplitude-dependent speed of sound (AD-SoS), bone transmission time (BTT), Ultrasound Bone Profile Index, as QUS parameters, L1-L4 and femoral neck BMD by DXA were assessed at baseline and after 18 months; serum bone-specific alkaline phosphatase (BSAP) and C-telopeptide of type 1 collagen were measured at baseline, 9 and 18 months. RESULTS: FRAX (without BMD) derived 10-years probability of major fractures and hip fractures were significantly associated with AD-SoS (r = -0.381, P = < 0.001 and r = -0.370, P < 0.001, respectively), Ultrasound Bone Profile Index (r = -0.434, P ≤ 0.001 and r = -0.409, P = < 0.001, respectively), BTT (r = -0.309, P = 0.002 and r = -0.340, P = 0.001, respectively). The median percent changes of AD-SoS (-3.71 [-5.38 to 0.11] vs -0.7 [-4.15 to 0.83], P = 0.02 respectively), BTT (-8.4 [-14.91 to -3.53] vs -1 [-5.72 to 3.75], P < 0.001 respectively) were significantly different between AIs users and controls. The same trend was observed for DXA measurements. BSAP and C-telopeptide of type 1 collagen significantly changed in AIs users. AD-SoS was associated with change of BMD at lumbar spine (ß, 0.16; SE, 0.08; P = 0.04) and change of BSAP (ß, -0.04; SE, 0.02; P = 0.04). CONCLUSIONS: Phalangeal QUS appeared a useful tool to evaluate bone quality in BC women on AIs.

Effects of strontium ranelate on bone mass and bone turnover in women with thalassemia major-related osteoporosis.

Subjects affected by thalassemia major (TM) often have reduced bone mass and increased fracture risk. Strontium ranelate (SrR) is an effective treatment for postmenopausal and male osteoporosis. To date, no data exist on the use of SrR in the treatment of TM-related osteoporosis. Our aim was to evaluate the effects of SrR on bone mineral density (BMD), bone turnover markers and inhibitors of Wnt signaling (sclerostin and DKK-1). Twenty-four TM osteoporotic women were randomized to receive daily SrR 2 g or placebo in addition to calcium carbonate (1,000 mg) and vitamin D (800 IU). BMD at the lumbar spine and femoral neck, bone turnover markers (C-terminal telopeptide of procollagen type I [CTX], bone-specific alkaline phosphatase [BSAP]) and insulin-like growth factor-1 (IGF-1), sclerostin and DKK-1 were assessed at baseline and after 24 months. Back pain was measured by visual analog scale (VAS) every 6 months. After 24 months, TM women treated with SrR had increased their spine BMD values in comparison to baseline (p < 0.05). Moreover, they also exhibited a reduction of CTX and sclerostin levels (but not DKK-1) and exhibited an increase of BSAP and IGF-1 (p < 0.05); however, no significant changes were observed in the placebo group. In the SrR group, a reduction of back pain was observed after 18 months in comparison to baseline (p < 0.05) and after 24 months in comparison to placebo (p < 0.05). Our study reports for the first time the effects of SrR in the treatment of TM-related osteoporosis. SrR treatment improved BMD and normalized bone turnover markers, as well as lowering sclerostin serum levels.

Activity of pegylated liposomal doxorubicin in combination with gemcitabine in triple negative breast cancer with skin involvement: two case reports.

Breast carcinoma (BC) is a heterogeneous disease in terms of histology, therapeutic response, dissemination patterns to distant sites and patient outcomes. Triple-negative breast cancer (TNBC), defined by the lack of protein expression of estrogen and progesterone receptors and the absence of HER2 protein overexpression (ER-/PR-/HER2-) has significant clinical implications due to their poor prognosis and the lack of targeted agents. Skin involvement is one of the most distressing presentations of locally recurrent breast cancer and few studies have identified effective agents in this setting. In fact, the increasing use of anthracycline/taxane-based chemotherapy in the neoadjuvant and/or adjuvant settings has led to investigate new cytotoxic therapies such as the combination of pegylated liposomal doxorubicin (PLD) with gemcitabine. Here, we report two cases of disseminated TNBC with extensive cutaneous metastases and a remarkable response to PLD in combination with gemcitabine. Further investigations are needed to confirm the efficacy of this regimen in skin involvement and TNBC.
