    Ep. 88 Beyond First-Line Therapy: Treatment Strategies for Advanced Neuroendocrine Tumors with Dr. Mark Lewis

    Few oncologists know neuroendocrine tumors from both sides of the exam table: first as a patient diagnosed during training, and now as the doctor treating them. This physician brings both perspectives to one pressing question: when a tumor progresses on a somatostatin analog, what comes next? On this episode of BackTable Tumor Board, Dr. Aman Chauhan, a medical oncologist at UCSF, interviews Dr. Mark Lewis, director of gastrointestinal oncology at Intermountain Health in Salt Lake City, about treatment strategies for advanced neuroendocrine tumors beyond first-line therapy. They start with what progression on a somatostatin analog really means, how grade, Ki-67, primary site, and the pace of liver disease shape the next step, and why observation is sometimes the right call. Dr. Lewis explains how he sets expectations for PRRT after NETTER-1 and NETTER-2, including the small but real risk of secondary myelodysplasia and leukemia. --- Get the BackTable apphttps://www.backtable.com/app --- This podcast is supported by Exelixishttps://www.exelixis.com/ --- Timestamps 00:00 - Introduction02:22 - Progression on a Somatostatin Analog05:34 - Tumor Biology, Grade, and Observation12:51 - Somatostatin Analogs and Carcinoid Syndrome18:50 - PRRT After NETTER-1 and NETTER-225:56 - Chemotherapy Versus Targeted Therapy32:35 - The CABINET Trial and Cabozantinib38:39 - Dosing and Toxicity of Oral Therapy43:57 - Liver-Directed Therapy and Rebiopsy48:08 - Future Trials and Alpha Emitters50:47 - When to Stop Somatostatin Analogs54:27 - Practice-Changing Trials and Sequencing Lessons59:25 - Closing Remarks --- More about this episode The conversation then turns to systemic therapy: where capecitabine and temozolomide still fit, the trade-offs of earlier targeted agents, and the inclusive design of the CABINET trial of cabozantinib in pancreatic and extra-pancreatic NETs. Dr. Lewis describes why an oral therapy matters for rural patients who cannot easily reach a center that offers PRRT, and both doctors share how they dose oral therapy and watch for early toxicity. They close with when to rebiopsy a disease that is changing, alpha emitters on the horizon, when to stop a somatostatin analog, and the sequencing mistake Dr. Lewis most wants listeners to avoid: doing something because you can rather than because you should. --- Resources Phase 3 Trial of Cabozantinib to Treat Advanced Neuroendocrine Tumors (CABINET).

    Ep. 87 Diagnosis & Management of Advanced HER2-Negative Upper GI Cancers with Dr. Ronan Hsieh and Dr. Dani Castillo

    Five years ago, first-line treatment for advanced HER2-negative gastroesophageal cancer meant chemotherapy; today claudin 18.2, PD-L1, and mismatch repair status shape the plan, often for a patient who cannot afford to wait for the results. On this episode of the BackTable GI Oncology Creator Weekend™, host Dr. Kate Baker interviews medical oncologists Dr. Ronan Hsieh and Dr. Dani Castillo about the diagnosis and management of advanced HER2-negative upper GI cancers. They discuss the biomarker workup at diagnosis, next-generation sequencing and liquid biopsy, when to biopsy metastatic sites, and why both guests start chemotherapy before every result is available. --- Get the BackTable apphttps://www.backtable.com/app --- Timestamps 00:00 - Introduction01:32 - Diagnosis and Biomarker Testing04:25 - Circulating Tumor DNA 06:31 - Starting Chemotherapy Before Biomarker Results09:10 - First-Line Therapy and Zolbetuximab Toxicity14:46 - Sequencing Therapy in Double Expressors21:11 - Clinical Trials and Emerging Targets24:54 - Immunotherapy Eligibility and Autoimmune Disease29:26 - Obstruction, Bleeding, and Multidisciplinary Care32:30 - Supportive Care36:50 - Future Directions39:36 - Organ Preservation and Closing Remarks --- More about this episode The conversation covers first-line therapy based on the SPOTLIGHT, GLOW, and CheckMate 649 trials, practical strategies for the nausea and vomiting that come with zolbetuximab, and how to sequence treatment when a tumor is positive for both claudin 18.2 and PD-L1, including the ILUSTRO cohort 4 data and the ongoing LUCERNA trial. Dr. Hsieh and Dr. Castillo make the case for offering clinical trials early, discuss immunotherapy in patients with autoimmune disease, and explain how stents, feeding tubes, and palliative radiation help manage obstruction and bleeding. They close on supportive care, from palliative medicine and dietitians to social work and psycho-oncology, and on organ preservation in mismatch repair-deficient disease, a reminder that caring for these patients takes a whole team. --- Resources Zolbetuximab plus mFOLFOX6 in CLDN18.2-positive, HER2-negative, untreated, locally advanced unresectable or metastatic gastric or gastro-oesophageal junction adenocarcinoma (SPOTLIGHT).
