Summary
Genomic tests help personalize early-stage breast cancer treatment. These tests guide decisions on chemotherapy and endocrine therapy for hormone receptor-positive tumors, improving patient outcomes.
Area of Science:
- Oncology
- Genomics
- Clinical Medicine
Background:
- Hormone receptor-positive (HR-positive) breast cancers are common.
- Endocrine therapy is effective for HR-positive tumors.
- Predicting chemotherapy needs and late recurrence risk is challenging using traditional methods.
Purpose of the Study:
- To review genomic tests for early-stage breast cancer prognosis.
- To guide adjuvant chemotherapy and endocrine therapy decisions.
- To assess the clinical utility of genomic assays.
Main Methods:
- Case presentation.
- Comprehensive literature review.
Main Results:
- Genomic tests are crucial for HR-positive breast cancers to identify patients who may not need chemotherapy.
- Traditional clinicopathological features are insufficient for predicting recurrence risk.
- HR-positive breast cancers can have late recurrence risks, necessitating longer endocrine therapy.
Conclusions:
- Genomic testing is evidence-based for chemotherapy recommendations in early-stage HR-positive breast cancer.
- Further research is needed to confirm genomic assays for predicting benefit from prolonged endocrine therapy.

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

02:30Genomic Imprinting and Inheritance
37.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

03:21Genome Size and the Evolution of New Genes
9.1K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

01:26Stages of Infection
65.3K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:22Stages of General Anesthesia
1.7K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

01:22Stages of Sleep
1.5K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
