Beyond efficacy, new therapies like bispecifics require significant institutional support. Clinicians need training for unfamiliar side effects like CRS, and facilities need resources like observation units and admission protocols, creating a steep implementation curve for clinical practice.

The arrival of multiple effective, biomarker-linked therapies for diseases like ovarian cancer creates a new, complex challenge for oncologists. No longer a matter of choosing the single best next option, treatment has become a strategic game of sequencing, requiring physicians to think "five plays ahead" to maximize the benefit of all available drugs over the patient's lifetime.

The POTOMAC trial's success adding durvalumab to BCG for non-muscle invasive bladder cancer introduces a major logistical hurdle. Urologists, who typically manage these patients, often lack the expertise to handle systemic immunotherapy side effects, creating uncertainty about which specialty will administer this new standard of care.

Unlike novel challenges from bispecifics, upcoming SCLC therapies like antibody-drug conjugates (ADCs) and radiopharmaceuticals will benefit from existing familiarity. Community practices are already comfortable with these drug classes from their use in breast cancer (ADCs) and prostate cancer (radioligands), which should streamline their integration.

A major trial on a less-frequent dosing schedule for denosumab in patients with bone metastases is being presented in a breast cancer session because it included both patient populations. This highlights the need for oncologists to monitor key research outside their specialty, as practice-changing data can emerge from unexpected places.

The physical separation of oncology specialists creates significant logistical hurdles to coordinated, multi-modal treatment. This discoordination can lead to suboptimal care, such as patients receiving neoadjuvant therapy without ever consulting a surgeon, highlighting a systemic flaw in care delivery.

Applying traditional, broad primary care launch strategies to highly targeted specialty therapies is a major risk. The complexity of stakeholders and decision-making in areas like oncology means old playbooks can make a company's efforts completely irrelevant.

Many community oncologists lack experience with pirtobrutinib, as its use was previously limited to third-line CLL. The new second-line FDA approval makes the drug relevant to a broader patient group, requiring these physicians to quickly learn its data and place in therapy.

Advanced diagnostics like Signatera ctDNA and therapies such as adjuvant nivolumab, while becoming standard in the US, are often unavailable in Europe and elsewhere. This creates a significant gap in care, making many cutting-edge discussions purely theoretical for a large portion of the world's oncologists and patients.
