Two Clinics, Two Opinions: Why Do Treatment Recommendations Differ?

Different treatment recommendations after a cancer diagnosis can be unsettling. However, they do not automatically mean that one of them is wrong. Especially in complex cases, there may be more than one medically reasonable path. What matters is the basis on which each recommendation is made.

A treatment decision is always based on the information available at a given point in time — such as histopathology findings, imaging, laboratory results, previous treatments, and, where appropriate, next-generation sequencing and molecular tumor boards in advanced solid tumors. If additional diagnostic information becomes available, the medical assessment may change accordingly.

Another important factor is that the same type of cancer can vary significantly on a biological level. Molecular alterations may influence treatment decisions and, in selected cases, open up additional therapeutic options. This is precisely where precision oncology comes into play.

However, specialist medical interpretation remains essential: not every identified molecular alteration is automatically therapeutically relevant.

There Is Not Always Only One Medically Reasonable Treatment Option

For many cancers, several treatment strategies may be appropriate. Which approach is preferred depends on a range of factors, including the expected clinical benefit, potential side effects, previous therapies, the course of the disease, and the individual circumstances of the patient.

Timing also matters. A treatment that was appropriate at an earlier stage may need to be reassessed after disease progression or following several previous lines of therapy.

Different recommendations can therefore reflect legitimate medical judgment and therapeutic flexibility — rather than a direct contradiction.

Not Every Treatment Is Available Everywhere

The location of a clinic can also influence which treatment options are available. Regulatory frameworks and national requirements differ between countries and may affect which therapies physicians are able to consider and use in a particular clinical situation.

Germany provides a differentiated regulatory framework. Under medically justified circumstances, approved medicines may also be used outside their formally authorized indication — known as off-label use.

In selected situations, this can expand the physician’s therapeutic options without removing the need for scientific evidence, a careful benefit-risk assessment, and compliance with the applicable legal requirements.

How Is Treatment Planning Carried Out at the Hallwang Clinic?

At the Hallwang Clinic, treatment planning begins with a comprehensive review of the individual case. Before a possible admission, the medical team evaluates the submitted medical records. Depending on the clinical question, additional diagnostic procedures such as molecular tumor analysis, liquid biopsy, or individualized tumor profiling may be considered.

Based on these findings, the medical team evaluates which treatment options appear medically appropriate. Established oncological therapies may be combined with precision medicine, targeted treatments, or immunotherapeutic approaches, depending on the individual disease and the available scientific evidence.

If the current evidence already supports a specific and medically justifiable option for an individual patient, the clinic may evaluate off-label use rather than waiting for broader international standardization.

“We do not wait for tomorrow’s consensus,” says Dr. Jens Nolting, oncologist at the Hallwang Clinic.

Would You Like to Better Understand Your Treatment Options?

A second medical opinion can help clarify unanswered questions and put possible alternatives into perspective. When faced with different recommendations, patients should above all be able to understand which findings and medical considerations each recommendation is based on. Helpful questions include:

• Which medical findings were taken into account?
• Would further diagnostic testing be useful?
• What alternative treatment options are available?
• How strong is the scientific evidence supporting the proposed treatment?
• What potential benefits and risks should be expected?

If you would like a second medical opinion, you can submit your medical records to the Hallwang Clinic team. Our physicians are available for a non-binding initial consultation.
