Non-small-cell lung cancer (NSCLC) is a highly heterogeneous disease that is frequently associated with a host of known oncogenic alterations. Advances in molecular diagnostics and drug development have facilitated the targeting of novel alterations such that the majority of NSCLC patients have driver mutations that are now clinically actionable. The goal of this review is to gain insights into clinical research and development principles by summary, analysis, and discussion of data on agents targeting known alterations in oncogene-driven, advanced NSCLC beyond those in the and the .

With recent advances, there was a need for multidisciplinary lung cancer healthcare providers from across Ontario to convene and review recent data from practical and implementation standpoints. The focus was on the following questions: (1) To what extent do patient (e.

New treatments, called targeted therapies (TT) and immunotherapies (IO), offer higher treatment efficacy and fewer side effects compared to traditional treatments but are accompanied by uncertainty and an unpredictable treatment course. There is a paucity of research on the experiences of individuals living with advanced or metastatic lung cancer receiving TT/IO, and even less is known about the supportive care needs of this population.

Many immune-related adverse events (irAEs) are well described; however, there is less information about opportunistic infections in cancer patients receiving ICIs.
Case Presentation: We describe the case of a 62-year-old woman with non-small cell lung cancer, who relapsed after surgical resection and chemotherapy.
Introduction: Aberrant expression of anaplastic lymphoma kinase (ALK) is found in 3%-7% of patients with non-small cell lung cancer (NSCLC). Alectinib is a tyrosine kinase inhibitor used as first-line treatment targeting ALK-positive tumors. We herein report two cases of appendicitis highlighting it as a rare, possible adverse event of treatment with alectinib.

Immune checkpoint inhibitors (ICIs) have been a frontline treatment, but recently developed KRAS-selective inhibitors, such as sotorasib, present new therapeutic options. We conducted a multi-center retrospective cohort study to gain insights into real-world treatment patterns and outcomes in patients with KRAS-positive advanced NSCLC receiving systemic therapy post-ICI treatment.

However, a very small minority of patients with cancer participate in clinical trials and many trials are not completed on time due to slow accrual. Issues with restrictive eligibility criteria can severely limit the patients who can access trials, without any convincing evidence that these restrictions impact patient safety.

High prices are driven in part by exploding drug development costs, which, in turn, are driven by essential but excessive regulation. Burdensome regulation also delays drug development, and this can translate into thousands of life-years lost.

For these patients, little is known about the impact of palliative care consultation on outcomes such as mortality, hospital admissions, or emergency department visits. The aim of this study is to determine if referral to supportive and palliative care in patients with malignant pleural mesothelioma is associated with survival and decreased hospital admissions and emergency department visits.

However, not all patients derive durable benefit and resistance to immune checkpoint blockade is common. Understanding mechanisms of resistance-which can include defects in DNA damage response and repair pathways, alterations or functional mutations in STK11/LKB1, alterations in antigen-presentation pathways, and immunosuppressive cellular subsets within the tumor microenvironment-and developing effective therapies to overcome them, remains an unmet need.

With high programmed death-ligand 1 (PD-L1) expression (tumor proportion score ≥50%), options include programmed cell death protein 1 or PD-L1 inhibitor with or without chemotherapy. A cut-point of greater than or equal to 50% defines PD-L1-high, but a more precise PD-L1 tumor proportion score may be an important predictor of outcomes.

Identifying these priorities can help ensure that Canadian cancer care continues to meet the needs of its patients. In our previous research, compassion and empathy were identified as important physician attributes, with answers like knowledge, professionalism or communication less common.

Backorders impacted the supply of intravenous H2RAs at our center, and it was removed as routine premedication. The authors compared the incidence of IRR in patients treated without H2RA to patients receiving standard H2RA premedication.

To date, patients with cancer account for 69% of MAiD deaths, yet little information is available about these patients. We reviewed disease and treatment characteristics of patients with cancer who underwent MAiD to better understand this population and identify gaps in our current system of care.

Several agents targeting KRAS G12C have recently entered clinical development. Sotorasib, a first-in-class specific small molecule that irreversibly inhibits KRAS G12C, has since obtained Health Canada approval.

Apart from advances in radiation therapy, progress in the systemic treatment of SCLC had been stagnant for over three decades despite multiple attempts to develop alternative therapeutic options that could improve responses and survival. Recent promising developments in first-line and subsequent therapeutic approaches prompted a Canadian Expert Panel to convene to review evidence, discuss practice patterns, and reach a consensus on the treatment of extensive-stage SCLC (ES-SCLC).

Local therapy-surgery or stereotactic body radiotherapy (SBRT)-with adjuvant chemotherapy may be appropriate for very early (T1-T2, N0) disease. There is variability in the management of these cases, which may lead to variability in patient outcomes.
