Medical Professional Clarifies Implications of Biden's 'Vigorous' Prostate Cancer Diagnosis

President Joe Biden has been diagnosed with an aggressive form of prostate cancer that has spread to his bones. To understand the term 'aggressive,' it's crucial to examine factors such as the cancer's grade, stage, and genetic makeup.

Urologic surgeons who specialize in diagnosing and treating prostate cancer often explain that aggressiveness is not determined by a single factor. Rather, it relies on understanding the tumor's grade, where it has spread, and its genetic fingerprint.

Cancer's Grade: The Key to Understanding Tumor Potential

The cancer's grade is one significant piece of the puzzle. After a prostate biopsy, a pathologist examines the tissue to assess the cancer cells' appearance. High-grade cancer cells display chaotic growth patterns, compared to the organized cells of a healthy prostate.

Cancer grades are organized into grade groups that range from 1 (least aggressive) to 5 (most aggressive). Biden's Gleason 9 cancer falls into grade group 5, indicating highly abnormal cells that have strong potential for rapid growth and spread. However, even high-grade cancers can remain confined to the prostate for a duration, highlighting the importance of also assessing the tumor's stage.

Staging: A Map of Cancer Location and Progression

The tumor's stage describes how far the cancer has spread beyond its initial site. Medical professionals use physical exams, imaging scans, and lab tests to stage prostate cancer. In general, prostate cancer can be localized (grades 1 to 2), locally advanced (Stage 3), or metastatic (Stage 4).

Localized cancer is only within the prostate. It may not be considered aggressive and can often be monitored.
Locally advanced cancer has spread out from the prostate and is growing in nearby tissues.
Metastatic cancer has spread to distant parts of the body, such as the bones (as in Biden's case). This type of cancer is advanced and aggressive because it can travel and form new tumors.

The tumor's stage significantly influences treatment options and goals. Localized or some locally advanced cancers may be treated with surgery or radiation, aiming for a cure, while metastatic cancer often focuses on controlling growth, managing symptoms, and maintaining quality of life.

Genetics: Exploring Cancer's DNA Blueprint

Besides grade and stage, doctors are increasingly using a cancer's genomic profile to gain deeper insights into its behavior and potential treatment pathways. Genomic testing can identify specific genetic alterations in the cancer cells, helping tailor treatments to individual patients.

In early-stage prostate cancer, genomic tests can help clarify the risk of the cancer progressing, aiding in decisions about active surveillance or immediate treatment. In advanced or metastatic prostate cancer, identifying specific mutations is critical, particularly for mutations in genes such as BRCA1 and BRCA2.

These mutations can make the cancer more aggressive but also potentially susceptible to specific types of drugs, such as PARP inhibitors, especially if the cancer becomes resistant to hormone therapy. It is now recommended that genomic testing be performed on all men with metastatic prostate cancer to identify these actionable mutations.

President Biden's diagnosis underscores the important role of understanding the various factors that contribute to the aggressiveness of cancer. Despite the challenges posed by an aggressive prostate cancer, advances in genomics, imaging, and targeted therapies offer hope for improved outcomes, even for patients with advanced disease.
