FAQ: What is Adjuvant Therapy, and How Can It Help Patients with an Early Stage Cancer?


When patients are found to have a cancer that is at an earlier stage that may be able to be cured with a “local therapy” such as surgery or radiation, we know that these cancers can recur months or years later, .This is presumably because of micrometastatic deposits traveling n the bloodstream, which cause distant recurrences, or in the region of the primary tumor, causing regional recurrences.

For many cancers, there is also a proven value in giving additional therapy to address the possibility of any invisible disease beyond what was seen on scans and by the surgeon.  This is often systemic therapy such as chemotherapy or targeted therapy, and it may also include radiation given along with or instead of systemic therapy.

When given before the potentially curative local therapy, this is called neoadjuvant (or sometimes pre-operative or induction) therapy. .When given following the local therapy, it is called adjuvant therapy, coming from the meaning of  the word adjuvant as “helper”. While there are certain advantages to a neoadjuvant approach, giving the additional treatment later has a couple of its own key advantages.

Cancer Ouija Boards, Umbrellas, and Baskets: The Evolution of Genomic Oncology


Cancer treatment is in the midst of a transformation in real time.  Genomic testing of a tumor– looking for a wide range of dozens to potentially hundreds of markers at a time — is moving quickly from bleeding edge to mass adoption, at least in the US. This change is partly driven by ever-changing data and ever-changing clinical experience, partly driven by the general promise felt by patients and clinicians alike that new information will lead to vast improvements in our understanding and therapeutic options, and (lest we be naïve) partly driven by marketing from institutions and diagnostics companies who stand to gain by promoting this work.

That there are potential gains is undeniable – regardless of what the future may bring, even today it is a tangible gain to avoid missing the immediately actionable findings such as an EGFR mutation (for someone with  non-small cell lung cancer (NSCLC), for instance), but it can find many less common but clearly “actionable” mutations ranging from HER-2/neu to BRAF or a few others that are now mentioned in the guidelines developed by the National Comprehensive Cancer Network (NCCN) that typically lead to insurer coverage of the treatments recognized as effective for these rare mutations, which range from <1% to 3-4% of the lung cancer population.

But these tests are not going to offer only unmitigated positive opportunities. Aside from the cost of several thousand dollars per tumor profile performed, the results of these profiling tests most often reveal not a clearly actionable mutation, but one or more rare mutations that are accompanied by a synopsis of lab-based suggestions for unapproved and clinically untested options in that particular tumor type from the testing company. While a patient and their oncologist may say that they will ignore treatment options that are poorly studied and essentially just wildly speculative (there is a rather weak correlation between cancer treatments that work in the lab and those that are safe and clearly active in human cancer patients), that’s easier said than done. Instead, the molecular results often lead oncologists to be tempted to practice the black art of using the profile as a “medical Ouija board” to cobble together a treatment plan with no good clinical evidence to support it, all too often bypassing the treatments that are well established as helping improve treatment options in thousands of cancer patients with that tumor type.
