Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
Cushing Syndrome I: Introduction01:26

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Adrenal Gland Disorders01:27

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Area of Science:

  • Endocrinology
  • Oncology
  • Genetics

Background:

  • Adrenocortical carcinoma (ACC) is a rare malignancy with increasing research focus.
  • Previous understanding of ACC pathogenesis, including Wnt/β-catenin and IGF-2 pathways, is updated.
  • Despite advances, key drivers of ACC malignancy remain unidentified.

Purpose of the Study:

  • To provide an updated review of recent advances in adrenocortical carcinoma research since 2006.
  • To highlight current diagnostic and therapeutic strategies for ACC.
  • To emphasize the need for novel treatment approaches.

Main Methods:

  • Review of recent literature on adrenocortical carcinoma.
  • Analysis of signaling pathways, diagnostic workup, and treatment modalities.
  • Discussion of ongoing research, including omics approaches and next-generation sequencing.

Main Results:

  • Wnt/β-catenin and IGF-2 signaling are frequently altered but insufficient for malignant transformation.
  • Comprehensive hormonal assessment and advanced imaging are crucial for diagnosis.
  • Complete surgical resection is recommended for localized tumors, with adjuvant mitotane improving outcomes.
  • Mitotane plus chemotherapy is the standard first-line treatment for advanced ACC, though salvage therapies are often needed.

Conclusions:

  • ACC diagnosis relies on hormonal assessment and imaging, with surgery as a primary curative option.
  • Adjuvant mitotane and current chemotherapy regimens improve outcomes but do not eliminate the need for new therapies.
  • Further research, including omics and sequencing, is essential for understanding ACC pathogenesis and developing novel treatments.
