Evolving Paradigms in Oncology

Dr. Ticiana Leal from Emory University's Winship Cancer Institute and Dr. Wade Iams from Tennessee Oncology discussed recognizing and managing Lambert-Eaton myasthenic syndrome (LEMS) in patients with small-cell lung cancer (SCLC). Cancer-associated LEMS affects approximately 3% of patients with SCLC but remains underdiagnosed in up to 90% of cases due to symptom overlap with disease progression or treatment effects in busy oncology settings.

LEMS results from voltage-gated calcium channel (VGCC) antibodies causing muscle weakness, autonomic dysfunction, and decreased reflexes. The classic triad includes proximal muscle weakness, orthostatic hypotension, and hyporeflexia. Updated NCCN guidelines now recommend VGCC antibody testing for suspected neurologic paraneoplastic syndromes, with 8-day median turnaround time making diagnosis feasible.

This program reviews evolving first-line management of advanced squamous cell carcinoma of the anal canal (SCAC), a rare but increasing human papillomavirus-driven malignancy with historically limited evidence to guide treatment. Although carboplatin and paclitaxel had been the prior standard based on phase 2 data, the phase 3 POD1UM-303 trial established carboplatin, paclitaxel, and the PD-1 inhibitor retifanlimab as a new NCCN category 1 first-line option, demonstrating improvements in response rate, progression-free survival, overall survival, and durability of response. Benefit appears consistent across patient subgroups, and no validated biomarkers currently guide treatment selection, supporting broad use in eligible patients. Management beyond first line remains a major unmet need, with treatment individualized based on timing of progression and clinical factors, and clinical trial participation encouraged. Practical considerations include proactive toxicity monitoring, logistical challenges of therapy, and the importance of multidisciplinary care. Because SCAC is treatment-sensitive, selected patients may achieve durable remission, highlighting the potential for long-term disease control with coordinated systemic and local approaches.

Expert clinicians discuss best practices in implementing more widespread and comprehensive biomarker testing in early-stage non-small cell lung cancer (NSCLC). Practical considerations are discussed that can be integrated into future clinical practice decisions.

Early-stage squamous cell carcinoma of the esophagus can often be managed with minimally invasive treatments. Endoscopic resection techniques, such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD), are preferred for superficial, localized tumors without lymph node involvement. For patients unsuitable for endoscopic therapy, esophagectomy remains the standard surgical option. In select cases, chemoradiotherapy may be considered as a non-surgical alternative. Careful staging, patient selection, and multidisciplinary evaluation are crucial to achieve optimal outcomes.

Tara Graff, DO, discusses how chronic lymphocytic leukemia treatment has evolved beyond the traditional “this or that” approach to include personalized therapy selection based on patient preferences, genetic risk factors, and disease characteristics, with new all-oral combination regimens offering fixed-duration options that are particularly transformative for high-risk patients with TP53 mutations or 17p deletions.

Virginia Kaklamani, MD, DSc; and Megan Kruse, MD, discuss how advances in hormone receptor-positive metastatic breast cancer treatment, including ESR1 mutation testing and elacestrant therapy, help physicians optimize patient care and improve outcomes through personalized treatment selection.

Richard S. Finn, MD; and Amit G. Singal, MD, MS, discuss how systemic therapy plays a growing role in hepatocellular carcinoma (HCC) management, particularly in embolization-eligible and advanced stages. Combining systemic therapies with locoregional treatments like transarterial chemoembolization has shown potential in overcoming resistance mechanisms. Trials like LEAP-012 and EMERALD-1 support this approach, indicating enhanced efficacy. Tyrosine kinase inhibitor (TKI)+immune checkpoint inhibitor combinations offer advantages over TKI monotherapy, but challenges remain in clinical adoption. Lenvatinib, a key player in first-line treatment, shows promise across stages and may extend to second-line therapy.

Robert Motzer, MD, Elizabeth Plimack, MD, MS, and Brian Rini, MD discuss recent treatment updates for patients with advanced renal cell carcinoma (RCC) and their implications for the RCC treatment landscape and clinical practice.
