Prostate cancer (PC) is a hormone-sensitive tumor. Androgen deprivation therapy (ADT) is the cornerstone of systemic therapy for patients with intermediate or high-risk localized, recurrent, and metastatic prostate cancer. Although generally well tolerated, ADT can lead to short- and long-term adverse events that can worsen the quality of life of patients with PC.

Background: Lung cancer (LC) tissue for immunological characterization is often scarce. We explored and compared T cell characteristics between broncho-alveolar lavage from tumor affected (t-BAL) and contralateral lung (cl-BAL), with matched peripheral blood (PB).

Methods: BAL and PB were collected during bronchoscopy for diagnostic and/or therapeutic purposes in patients with monolateral primary lesion.

The treatment landscape of advanced non-small cell lung cancer (NSCLC) patients has dramatically changed over the past 10 years, particularly thanks to the advent and development of several tyrosine kinase inhibitors (TKI) targeting oncogenic drivers. Among them, patients bearing anaplastic lymphoma kinase (ALK) translocations, which are causative of 3-5% of all advanced NSCLC, have seen dramatically improved their clinical outcomes moving life expectancy at 5 years from less than 5% to 50%. In fact, multiple ALK inhibitors (ALKi) entered in the therapeutic algorithm of ALK+ patients, multiplying their treatment opportunities.

Personalized treatment based on driver molecular alterations, such as ALK rearrangement, has revolutionized the therapeutic management of advanced oncogene-addicted NSCLC patients. Multiple effective ALK tyrosine kinase inhibitors (TKIs), with the amelioration of the activity at central nervous system level, are now available, leading to substantial prognosis improvement. The exposure to TKIs triggers resistance mechanisms and the sequential administration of other TKIs and chemotherapy is, for the most part, not targeted.

The advent of immune-checkpoint inhibitors targeting the programmed cell death-1 (PD-1)/programmed death ligand-1 (PD-L1) axis, both as monotherapy and in combination strategies, produced a paradigm change of the treatment algorithm for metastatic, non-oncogene addicted, non-small cell lung cancer (NSCLC) patients. Although the great efficacy and the optimal tolerability emerging from clinical studies has been confirmed for the majority of patients treated in the real-word scenario, however the potential activity and safety profile of these agents in uncommon NSCLC populations remains still controversial. Particularly, patients with previously diagnosed autoimmune disease or concomitant steroids treatment at the time of immunotherapy initiation represent two special subgroups of patients not unusual in the real-word practice, to whom the clinical implication of immune-checkpoint inhibitors administration is largely unknown.

Purpose: COVID-19 cancer patients (C19-CP) represent a population at high risk for mortality, whose clinical characteristics are still unknown in the second SARS-CoV-2 wave. The aim of this retrospective study was to compare epidemiology and clinical presentation of C19-CP referring to the emergency department (ED) of our institution (San Luigi Gonzaga University Hospital, Orbassano, Turin, Italy), in a 3-week observation period of the first and second COVID-19 waves, starting from the introduction of the corresponding national lockdowns.

Methods: We retrieved ED admissions from March 9 to 29, 2020, for the first wave, and from October 24 to November 13, 2020, for the second wave.

Article Synopsis
  • First-line treatment of metastatic non-small cell lung cancer (NSCLC) patients with high PD-L1 expression using pembrolizumab is supported, with a median overall survival of 15.8 months reported in a study of 974 patients.
  • After disease progression, a significant number of patients (55.9%) did not receive further treatment, often due to older age and poorer health status.
  • Among those who switched to second-line treatments, patients receiving pembrolizumab in combination with local ablative therapies had improved survival rates compared to those who only received pembrolizumab.

Background: The role of immune-related adverse events (irAEs), as a surrogate predictor of the efficacy of checkpoint inhibitors, has not yet been described in the setting of first-line, single-agent pembrolizumab for patients with metastatic non-small-cell lung-cancer (NSCLC) with a programmed death-ligand 1 (PD-L1) expression of ≥ 50%.

Patients And Methods: We previously conducted a multicenter retrospective analysis in patients with treatment-naive metastatic NSCLC and a PD-L1 expression of ≥ 50% receiving first-line pembrolizumab. Here, we report the results of the irAE analysis and the potential correlation between irAEs and clinical outcomes.
