However, many other inhibitors of this pathway are promising; nevertheless their development is actually limited by toxicity, mainly cutaneous (rash), digestive (diarrhea) and endocrine (diabetes).

Systemic chemotherapy for pancreatic adenocarcinoma (PDAC) and cholangiocarcinoma (CC) with peritoneal metastases (PM) is affected by several pharmacological shortcomings and low clinical efficacy. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is expected to maximize exposure of peritoneal nodules to antiblastic agents. This study aims to evaluate safety and efficacy of PIPAC for PM of PDAC and CC origin.

This is a retrospective analysis of consecutive PDAC and CC cases with PM treated with PIPAC at two European referral centers for peritoneal disease. We prospectively recorded from August 2016 to May 2019 demographic, clinical, surgical, and oncological data. We performed a feasibility and safety assessment and an efficacy analysis based on clinical and pathological regression.

Twenty patients with PM from PDAC (14) and CC (six) underwent 45 PIPAC administrations. Cisplatin-doxorubicin or oxaliplatin were administered to eight and 12 patients, respectively. We experienced one intraoperative are encouraging, recommending PIPAC in prospective, controlled trials in the palliative setting or the first line chemotherapy for PM from PDAC and CC.

EPIC1 is an oncogenic long non-coding ribonucleic acid (RNA) that promotes cell growth and cell-cycle progression and inhibits apoptosis in several cancer cell lines. However, clinical studies on EPIC1 in breast cancer, specifically in the neoadjuvant setting, are relatively few.

Patients treated with weekly paclitaxel-cisplatin-based neoadjuvant chemotherapy after core-needle biopsy were included in the study. Real-time quantitative polymerase chain reaction assays were performed to detect EPIC1 expression.

Among all patients included in this study (

 = 111), higher EPIC1 expression was associated with estrogen receptor negativity, human epidermal growth factor receptor 2 positivity, higher Ki67 index, and higher histologic grade. Multivariate analysis suggested that EPIC1 expression was an independent predictive factor for pathological complete response, with a significant interaction between EPIC1 expression and age. The Kaplan-Meier Plotter dataset suggested that the EPIC1 high-expression group shoitive premenopausal subgroup. It may also help identify candidate responders and determine treatment strategies.Colorectal cancer (CRC) is a heterogeneous disease representing a therapeutic challenge, which is further complicated by the common occurrence of several molecular alterations that confer resistance to standard chemotherapy and targeted agents. Mechanisms of resistance have been identified at multiple levels in the epidermal growth factor receptor (EGFR) pathway, including mutations in KRAS, NRAS, and BRAFV600E, and in the HER2 and MET receptors. These alterations represent oncogenic drivers that may co-exist in the same tumor with other primary and acquired alterations via a clonal selection process. Other molecular alterations include DNA damage repair mechanisms and rare kinase fusions, potentially offering a rationale for new therapeutic strategies. In recent years, genomic analysis has been expanded by a more complex study of epigenomic, transcriptomic, and microenvironment features. The Consensus Molecular Subtype (CMS) classification describes four CRC subtypes with distinct biological characteristics that show prognostic and potential predictive value in the clinical setting. Here, we review the panorama of actionable targets in CRC, and the developments in more recent molecular tests, such as liquid biopsy analysis, which are increasingly offering clinicians a means of ensuring optimal tailored treatments for patients with metastatic CRC according to their evolving molecular profile and treatment history.The identification of oncogenic drivers, and the subsequent development of targeted therapies established biomarker-based care for metastatic non-small cell lung cancer (NSCLC). Biomarker testing is standard of care in NSCLC patients with adenocarcinoma because multiple targeted therapies are available. Rearranged during transfection (RET) rearrangements were identified as oncogenic drivers in NSCLC, and are more common among younger patients, adenocarcinoma histology, and patients with a history of never smoking. The prevalence is estimated to be 1-2% among patients with adenocarcinoma histology. The most common rearrangement is between intron 11 of the RET gene and intron 15 of the KIF5B gene, and the next most frequent rearrangement is with the CCDC6 gene. RET rearrangements lead to constitutive activation of the RET tyrosine kinase and increased cell proliferation, migration, and survival. Phase II studies investigated the activity of multi-targeted tyrosine kinase inhibitors in patients with NSCLC with a confirmed RET rearrangement. These agents have limited potency against RET, and activity against the epidermal growth factor receptor and vascular endothelial growth factor pathways. These agents revealed modest activity, and were poorly tolerated due to the off-target toxicities. These struggles contributed to the development of more potent and specific RET tyrosine kinase inhibitors. Preliminary results from early phase trials of selpercatinib (LOXO-292) and pralsetinib (BLU-667) revealed promising efficacy and improved tolerability. The availability of these agents will make routine testing for RET rearrangements a priority.Atherosclerosis is considered an irreversible process, with crucial contribution of inflammation and immune cells. Impact of cancer immunotherapy on a partly immune-driven disease, such as atherosclerosis, is poorly understood, but preclinical models suggest its worsening on programmed death/ligand-1 (PD-1/PD-L1) inhibitors. DMH1 mw In a previously reported cohort of 11 patients with non-small cell lung cancer (NSCLC) treated with nivolumab and pre-existing complicated atheromatous plaques, 3 patients had a dramatic radiologic reduction of aortic plaques while on nivolumab; of these 3, 2 died receiving no further treatment. link2 The remaining patient was an 83-year-old woman with history of arterial hypertension and hypothyroidism who was diagnosed with locally advanced squamous NSCLC. At relapse, complicated aortic atheromatous plaques were demonstrated on scans. The patient was then treated with nivolumab obtaining stable disease at radiological assessment, which also demonstrated almost complete vanishing of aortic plaques. After relapse and interval treatment with chemotherapy, she experienced new development of aortic atheromatous plaques. At further relapse she received atezolizumab, which yielded disease response and new reduction in aortic plaques, until nearly complete resolution. The observation of a repeated improvement of atheromatous plaques on treatment with PD-1/PD-L1 inhibitors favors the protective role of T cells on atheromatous plaques that is impaired by PD-L1 expression by plaque-associated macrophages. Validation by independent and prospective observation is needed.

(1) To determine the interobserver reliability of magnetic resonance classifications and lesion instability criteria for capitellar osteochondritis dissecans lesions and (2) to assess differences in reliability between subgroups.

Magnetic resonance images of 20 patients with capitellar osteochondritis dissecans were reviewed by 33 observers, 18 orthopaedic surgeons and 15 musculoskeletal radiologists. Observers were asked to classify the osteochondritis dissecans according to classifications developed by Hepple, Dipaola/Nelson, Itsubo, as well as to apply the lesion instability criteria of DeSmet/Kijowski and Satake. Interobserver agreement was calculated using the multirater kappa (k) coefficient.

Interobserver agreement ranged from slight to fair Hepple (k = 0.23); Dipaola/Nelson (k = 0.19); Itsubo (k = 0.18); DeSmet/Kijowksi (k = 0.16); Satake (k = 0.12). When classifications/instability criteria were dichotomized into either a stable or unstable osteochondritis dissecans, there was more agreement for Hepple (k = 0.52; p = .002), Dipaola/Nelson (k = 0.38; p = .015), DeSmet/Kijowski (k = 0.42; p = .001) and Satake (k = 0.41; p < .001). Overall, agreement was not associated with the number of years in practice or the number of osteochondritis dissecans cases encountered per year (p > .05).

One should be cautious when assigning grades using magnetic resonance classifications for capitellar osteochondritis dissecans. When making treatment decisions, one should rather use relatively simple distinctions (e.g. stable versus unstable osteochondritis dissecans; lateral wall intact versus not intact), as these are more reliable.

Individuals with higher-than-average melatonin concentrations are less likely to develop cancer. In cancer patients, psychosomatic coping patterns and treatment side effects are important indicators of cancer prevention and immune system deterioration. This study focused on changes in the urinary melatonin concentration, life resilience, and sleep quality in bladder cancer patients before, and 3 months after, treatment.

A controlled before-and-after study was performed. The subjects were patients who were previously diagnosed with bladder cancer and had received treatment (transurethral resection of bladder tumor + intravesical chemotherapy). Data from 23 subjects were analyzed.

The results showed a significant difference in the melatonin concentration before and after treatment (Wilcoxon signed-rank test,

 = -2.220,

 = 0.026). The melatonin concentration in 16 patients (70%) increased after treatment. The mean Pittsburgh Sleep Quality Index (PSQI) score before treatment was 7.348 (SD = 4.030), whicly because elderly individuals have strong personality traits and emotional stability and are not easily affected by life events or stress.Inflammatory bowel diseases are chronic relapsing immune-mediated diseases of the intestinal tract with multifaceted manifestations and treatment related morbidity. Faecal and blood tests, radiological, endoscopic and histologic investigations are now widely used for managing both ulcerative colitis and Crohn's disease. Over the years, a number of new investigations have been proposed but not widely adopted yet. Patients with Crohn's disease may have multiple causes of diarrhoea, not always attributable to disease exacerbation, but sometimes linked to bile acid malabsorption; we have a reliable serum test, C4, that allows us to recognize and treat this cause of diarrhoea efficaciously and not empirically, but it is not available or used widely. There is genetic inter-individual variability in drug responses, in terms of both efficacy and toxicity, leading to high rates of therapeutic failure. Patients treated with thiopurine or, more rarely, 5-aminosalicylic acid may suffer from unpredictable and serious adverse events, some of these with pathogenesis related to genetic variants myelosuppression, acute pancreatitis and nephrotoxicity.
