STK11 mutations correlate with poor prognosis for advanced NSCLC treated with first-line immunotherapy or chemo-immunotherapy according to KRAS, TP53, KEAP1, and SMARCA4 status.

Background: The upfront treatment of non-oncogene-addicted NSCLC relies on immunotherapy alone (ICI) or in combination with chemotherapy (CT-ICI). Genomic aberrations such as KRAS, TP53, KEAP1, SMARCA4, or STK11 may impact survival outcomes.

Methods: We performed an observational study of 145 patients treated with first-line IO or CT-ICI for advanced non-squamous (nsq) NSCLC at our institution tested with an extensive lab-developed NGS panel.

Circulating tumor DNA to guide diagnosis and treatment of localized and locally advanced non-small cell lung cancer.

Liquid biopsy is a minimally invasive method for biomarkers detection in body fluids, particularly in blood, which offers an elevated and growing number of clinical applications in oncology. As a result of the improvement in the techniques for DNA analysis, above all next-generation sequencing (NGS) assays, circulating tumor DNA (ctDNA) has become the most informing tumor-derived material for most types of cancer, including non-small cell lung cancer (NSCLC). Although ctDNA concentration is higher in patients with advanced tumors, it can be detected even in patients with early-stage disease.

Molecular and Genetic Advances in Small Cell Lung Cancer Landscape: From Homogeneity to Diversity.

Small cell lung cancer (SCLC) has been historically considered a homogeneous disease and thus approached as a single entity when it comes to clinical studies design and new treatments developments. However, increasing knowledge in the genetic and molecular landscape of this disease challenges this concept, opening the possibility that different subtypes might show differential vulnerability to treatments. In this narrative review, we gather the most relevant advances in genetic and molecular characterization of SCLC, focusing on how these discoveries may be used to design the path for a personalized treatment approach.

RET-MAP: An International Multicenter Study on Clinicobiologic Features and Treatment Response in Patients With Lung Cancer Harboring a RET Fusion.

Introduction: Nearly 1% to 2% of NSCLCs harbor RET fusions. Characterization of this rare population is still incomplete.

Methods: This retrospective multicenter study included patients with any-stage RET positive (RET+) NSCLC from 31 cancer centers.

Tumor infiltrating lymphocytes (TILs) as a predictive biomarker of response to checkpoint blockers in solid tumors: A systematic review.

Immunotherapy is a standard of care in many solid tumors but many patients derive limited benefit from it. There is increasing interest toward tumor infiltrating lymphocytes (TILs) since their presence may be related with good outcomes from treatment with immune checkpoint blockers. We aimed at systematically reviewing existing evidence about the role of TILs as possible predictors of response to immunotherapy in solid tumors.

Transient asymptomatic pulmonary opacities and interstitial lung disease in -mutated non-small cell lung cancer treated with osimertinib.

Introduction: Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved as first-line therapy for advanced -mutated non-small cell lung cancer (NSCLC). Some osimertinib-related interstitial lung diseases (ILDs) were shown to be transient, called transient asymptomatic pulmonary opacities (TAPO)-clinically benign pulmonary opacities that resolve despite continued osimertinib treatment-and are not associated with the clinical manifestations of typical TKI-associated ILDs.

Methods: In this multicentric study, we retrospectively analyzed 92 patients with -mutated NSCLC treated with osimertinib.

Tumor Growth Rate Decline despite Progressive Disease May Predict Improved Nivolumab Treatment Outcome in mRCC: When RECIST Is Not Enough.

Treatment response is usually assessed by the response evaluation criteria in solid tumors (RECIST). These criteria may not be adequate to evaluate the response to immunotherapy, considering the peculiar patterns of response reported with this therapy. With the advent of immunotherapy these criteria have been modified to include the evaluation of the peculiar responses seen with this type of therapy (iRECIST criteria), including pseudoprogressions and hyperprogressions.

Quality of life assessment in renal cell carcinoma Phase II and III clinical trials published between 2010 and 2020: a systematic review.

Quality of life (QoL) assessment is frequently not included among the end points of clinical trials (CTs) on renal cell carcinoma. Herein we aimed to describe the assessment and reporting of QoL in Phase II and Phase III CTs published between 2010 and 2020. A total of 25 CTs were included; 76% of trials included were conducted in metastatic renal cell carcinoma patients, while 20% of studies evaluated adjuvant systemic treatments.

Impact of HER2 assessment by CISH in urothelial carcinoma: A retrospective single-center experience.

Background: In recent years, HER2 amplification has been evaluated as a potential prognostic biomarker and therapeutic target in urothelial carcinoma (UC). In this retrospective study, we aimed at exploring the prognostic role of HER2 amplification in UC, measured by chromogenic in situ hybridization (CISH).

Methods: We retrospectively evaluated the presence of HER2 amplification by using CISH in 31 UC patients followed at a single institution between 2018 and 2020.

Expected and non-expected immune-related adverse events detectable by CT.

Purpose: Cancer treatments with immune checkpoint inhibitors (ICI) are associated with a unique set of drug toxicities called immune-related adverse events (irAES). The aim of the present study was to describe the radiological manifestation of irAES detectable by CT.

Method: Retrospective analysis of 284 patients treated with ICI for various types of advanced cancer; of them, 129 patients were selected, all having been treated with single-agent ICI, and all with a baseline CT scan and follow-up scans available at our Institute.

Immortal time bias in the association between toxicity and response for immune checkpoint inhibitors: a meta-analysis.

Only a minority of studies addressing the association between immune-related adverse events (IrAE) and outcome considered the immortal time bias, with conflicting results. PubMed, Embase, Web of Science and Scopus were searched through 2 January 2020. Studies reporting the impact of IrAE on outcome in patients treated with antiprogrammed death receptor 1 or PD-L1 were included.

Percutaneous radiofrequency ablation in intrahepatic cholangiocarcinoma: a retrospective single-center experience.

Very few data are available in literature about the role of radiofrequency ablation (RFA) in intrahepatic cholangiocarcinoma (ICC) and previous studies are mainly case reports and case series on a very small number of patients and nodules. In this study, we aimed to evaluate effectiveness and safety of RFA for the treatment of unresectable ICC. This is a retrospective observational cohort study comprising all consecutive patients treated with RFA for unresectable ICC at Policlinico Sant'Orsola Malpighi Hospital, Bologna, Italy.

First-line pembrolizumab in advanced non-small cell lung cancer patients with poor performance status.

Background: Pembrolizumab is the first-line standard of care for advanced non-small cell lung cancer (NSCLC) with a PD-L1 tumour proportion score (TPS) ≥ 50%. Eastern Cooperative Oncology Group performance status (PS) 2 patients may receive pembrolizumab, despite the absence of sustaining evidence.

Patients And Methods: GOIRC-2018-01 is a multicentre, retrospective, observational study.

Clinical significance of ROS1 5' deletions in non-small cell lung cancer.

Objectives: Patients harboring rearrangements of the ROS1 gene are eligible for first-line therapy with Crizotinib, which represents the best available treatment option. Diagnostic criteria, based on break-apart fluorescence in situ hybridization, were mirrored from ALK by analogy and include tumors with 5' deletions. However, the probability of response to Crizotinib in patients with 5' deletion in ROS1 is unknown given the rarity of this condition.

Combined Low Densities of FoxP3 and CD3 Tumor-Infiltrating Lymphocytes Identify Stage II Colorectal Cancer at High Risk of Progression.

The densities of CD3 and CD8 tumor-infiltrating lymphocytes (TILs), combined with tumor-node-metastasis (TNM) staging, have prognostic value for patients with nonmetastatic colorectal cancer. We compared the prognostic value of CD3 and FoxP3 TILs at the invasive front, TNM classifiers, and microsatellite (MS) status in a trial set of patients with stage II and III colorectal cancer ( = 413), by recursive partitioning with a classification and regression tree (CART). Significant prognostic factors and interactions were reassessed by logistic regression and Cox proportional-hazards modeling in the trial and a validation set ( = 215) of patients with stage II colorectal cancer.

Adjuvant chemotherapy for resected colorectal cancer metastases: Literature review and meta-analysis.

Surgical resection is the only option of cure for patients with metastatic colorectal cancer (CRC). However, the risk of recurrence within 18 mo after metastasectomy is around 75% and the liver is the most frequent site of relapse. The current international guidelines recommend an adjuvant therapy after surgical resection of CRC metastases despite the lower level of evidence (based on the quality of studies in this setting).
