As multiple new drugs like antibody-drug conjugates (ADCs) become available for SCLC, the critical research question will shift from *if* they work to *when* they should be used. Future biomarker strategies must focus on optimizing treatment sequences, considering factors like the drug's target and payload.

While liquid biopsies are a valuable, less invasive tool, a negative result is inconclusive for ruling out actionable mutations in NSCLC. It may simply mean the tumor isn't shedding enough DNA. Therefore, a negative liquid biopsy should never be the final word; it must be followed by a tissue biopsy to ensure patients don't miss out on targeted therapies.

To reduce treatment delays, pathologists should initiate biomarker testing reflexively. Waiting for a medical oncologist to order tests at a first visit is a system failure, wasting critical time and risking the need to retrieve archived samples.

The aggressive nature of small cell lung cancer (SCLC) demands immediate treatment, often within days. This urgency, while necessary for disease control, paradoxically restricts patients' ability to seek second opinions, process their diagnosis, or enroll in first-line clinical trials, which providers may bypass for faster standard care.

Unlike rare biomarkers that necessitate a 'test-and-wait' approach, IB6 is expressed in over 80-90% of NSCLC tumors. This ubiquity could make pre-screening unnecessary for drugs like Sigvotatug Vedotin, allowing clinicians to initiate targeted therapy much faster and for a broader patient population.

To make clinical trials more representative of real-world SCLC patients, who are often too sick to enroll, a pragmatic approach is emerging. Allowing one initial cycle of stabilizing chemotherapy before trial inclusion is a key strategy to broaden eligibility and gather more relevant data.

Integrating next-gen SCLC treatments like T-cell engagers requires more than education; it demands a physical and operational overhaul. Community practices must build infrastructure for 24-hour observation and establish proactive partnerships with specialists like ophthalmologists to manage novel toxicities.

For very early-stage small cell lung cancer, surgical resection is an important and perhaps underutilized option. Beyond its therapeutic potential, surgery provides a definitive pathological diagnosis, which is crucial as some cases that appear to be small cell on biopsy may actually be other tumor types, like atypical carcinoid.

Recognizing the rapid progression of SCLC, modern clinical trials like PRISM are adopting pragmatic designs. They allow patients to begin initial chemotherapy cycles before official enrollment, ensuring that the need for immediate care does not disqualify them from accessing novel investigational therapies.
