In this episode of the Ninja Nerd Podcast, Zach and Rob explore pancreatic and hepatobiliary cancers through four patient cases packed with clinical pearls.

We begin with a 63-year-old man presenting with painless jaundice, pruritus, and weight loss. Zach walks through the differential for obstructive cholestasis, covering malignant (pancreatic head cancer, cholangiocarcinoma, ampullary tumors) and benign (stones, strictures) causes. We emphasize RUQ ultrasound's role in assessing for ductal dilation, followed by pancreas-protocol CT and EUS-guided FNA to confirm pancreatic adenocarcinoma. Management hinges on resectability, with Zach outlining surgical criteria and adjuvant chemotherapy options.

Next, we discuss a 58-year-old man with cirrhosis and a newly detected liver nodule on routine surveillance. With an elevated AFP and classic arterial enhancement with portal venous washout on imaging, the diagnosis of hepatocellular carcinoma (HCC) becomes clear. We outline curative options for early-stage disease—including surgical resection and radiofrequency ablation—and review the role of transplant under Milan criteria.

Case three features a 48-year-old woman with primary sclerosing cholangitis and rising cholestasis, prompting a focused discussion on perihilar cholangiocarcinoma (Klatskin tumor). We highlight the role of MRCP for mapping strictures, followed by ERCP with brushings to confirm malignancy. With localized disease, Zach walks through surgical resection with liver wedge + bile duct excision, followed by adjuvant capecitabine, and offers guidance on palliative strategies for unresectable disease.

Finally, we examine a 72-year-old woman with a porcelain gallbladder and new mass—raising suspicion for gallbladder carcinoma. The case underscores the importance of RUQ ultrasound for polypoid lesions and how staging dictates surgery. For early T1a disease, simple laparoscopic cholecystectomy is curative; deeper invasion requires extended cholecystectomy.

We close with a summary of diagnostic strategies: ultrasound for ductal or gallbladder disease, triphasic CT or MRI for liver masses, MRCP for PSC patients, and pancreas-protocol CT for head-of-pancreas tumors. Each case reinforces the principle: start broad, refine with the right imaging, and let stage drive treatment.

In this episode of the Ninja Nerd Podcast, Zach and Rob discuss two high-yield, board-relevant cases highlighting the diagnosis, staging, and treatment of esophageal adenocarcinoma and intestinal-type gastric adenocarcinoma.

We begin with a 56-year-old man presenting with progressive dysphagia and unintentional weight loss. Zach breaks down the concern for distal esophageal adenocarcinoma in the long-standing GERD and Barrett's esophagus setting. We walk through the stepwise diagnostic process—starting with barium swallow, followed by EGD with biopsy, and endoscopic ultrasound (EUS) and CT chest/abdomen/pelvis for staging. Based on a staging result of T2 N1 M0, we discuss the standard approach of neoadjuvant chemoradiation followed by transthoracic esophagectomy, with comparisons to management of early mucosal disease and metastatic presentations.

Next, we pivot to a 63-year-old woman with chronic Helicobacter pylori gastritis, now presenting with early satiety, epigastric discomfort, and melena. The focus shifts to intestinal-type gastric adenocarcinoma, classically found along the lesser curvature. We review the appropriate use of EGD with biopsy as the first test in alarm dyspepsia, followed by CT imaging and EUS to assess depth and nodal involvement. With a staging result of T1b N0, we emphasize the role of subtotal (distal) gastrectomy with D2 lymph node dissection, and outline when perioperative chemotherapy or palliation (e.g., GOO stents, systemic chemo, trastuzumab for HER2⁺ tumors) becomes necessary.

Finally, we conclude with a rapid comparison of the two cases, highlighting shared themes: the importance of depth of invasion, nodal status, and the shift from endoscopic resection to surgical and systemic therapies based on stage.

Ninja Nerds,

Welcome to the Ninja Nerd Podcast with Zach and Rob! In this episode, we explore Amyloidosis, a complex disorder characterized by the misfolding and deposition of insoluble amyloid fibrils in tissues. We break down the different subtypes, including AL (light chain), AA (secondary), ATTR (transthyretin), and Aβ2M (β2 microglobulin), highlighting their unique pathogenesis, clinical manifestations, and diagnostic approaches.

Our discussion covers the systemic vs. localized forms of the disease, exploring how amyloid deposition can impact critical organs like the heart (restrictive cardiomyopathy), kidneys (nephrotic syndrome), nervous system (autonomic and peripheral neuropathy), and gastrointestinal tract. We also walk through essential diagnostic tools, including serum and urine electrophoresis, fat pad biopsy with Congo red staining, mass spectrometry, and advanced imaging techniques like cardiac MRI and PYP scanning for ATTR amyloidosis.

Finally, we break down the latest treatment strategies, from chemotherapy and autologous stem cell transplant for AL amyloidosis. Whether you’re preparing for exams, rotations, or just want to master this challenging topic, this episode is packed with high-yield insights to boost your understanding!

Welcome to the Ninja Nerd Podcast with Zach and Rob! In this episode, we dive deep into Lymphoma, breaking down its pathogenesis, clinical presentation, and the latest advancements in treatment. We explore the key differences between Hodgkin and Non-Hodgkin Lymphoma, examining the role of Reed-Sternberg cells, CD markers, and genetic mutations that define these malignancies.

Our discussion includes high-yield diagnostic tools like lymph node biopsy, flow cytometry, PET/CT imaging, and molecular studies, helping you differentiate between indolent and aggressive subtypes. We also analyze cutting-edge treatments, including immunotherapy, targeted monoclonal antibodies (e.g., rituximab), chemotherapy regimens like R-CHOP, and the role of stem cell transplantation in refractory cases.

Additionally, we cover disease progression, prognostic factors, and complications such as tumor lysis syndrome and secondary malignancies. Whether you’re studying for boards, preparing for clinical rotations, or just love hematology-oncology, this episode is packed with high-yield pearls you don’t want to miss!
