Abstract

Insights

Ceritinib shows modest benefit for patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) after alectinib treatment failure. Further investigation is warranted for this ALK-positive NSCLC patient population.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Alectinib is a standard treatment for anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC).
  • Resistance to alectinib develops in most patients, necessitating alternative therapies.
  • Limited data exist on the efficacy of ceritinib following alectinib treatment.

Purpose of the Study:

  • To evaluate the efficacy of ceritinib in patients with ALK-positive NSCLC who progressed on alectinib.
  • To assess treatment outcomes for ceritinib as a subsequent therapy after alectinib failure.

Main Methods:

  • Retrospective review of ALK-positive NSCLC patients treated at Kyoto University Hospital (2012-2017).
  • Identification of patients who received ceritinib after alectinib treatment.
  • Evaluation of overall response rate and progression-free survival for ceritinib.

Main Results:

  • Nine out of 35 ALK-positive NSCLC patients received ceritinib after alectinib.
  • Overall response rate to ceritinib was 44% (16% immediately after alectinib, 100% after chemotherapy).
  • Median progression-free survival with ceritinib was 4.4 months.

Conclusions:

  • Ceritinib demonstrated a modest clinical benefit in patients with ALK-positive NSCLC after alectinib failure.
  • Ceritinib may represent a viable treatment option in this specific clinical setting.
  • Sequential treatment strategies warrant further investigation for advanced NSCLC.

Self-Efficacy

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

Lung Capacity01:47

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Chromatin Position Affects Gene Expression

Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

Position and Displacement01:31

Position and Displacement

The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Serial Position Effect01:03

Serial Position Effect

The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...
