Send us a text Ninja Nerds! In this episode of the Ninja Nerd Podcast, Zach and Rob deliver a high-yield, case-based discussion on paraneoplastic syndromes, exploring how certain cancers cause systemic effects that extend beyond the primary tumor. We begin with SIADH in small-cell lung cancer, breaking down the classic lab pattern of hyponatremia with inappropriately concentrated urine and the dangers of seizures or osmotic demyelination from overcorrection. Next, we cover ectopic ACTH production from small-cell lung cancer, reviewing the clinical features of Cushing syndrome, stepwise testing, and complications like infections, thromboembolism, and severe metabolic derangements. The discussion moves into Lambert-Eaton myasthenic syndrome (LEMS), highlighting proximal muscle weakness that improves with activity, autonomic symptoms, and the link to voltage-gated calcium channel antibodies. We then review hypercalcemia of malignancy, focusing on PTHrP secretion by squamous lung cancers and the potential for acute kidney injury and arrhythmias. We shift to the neurologic realm with anti-NMDA receptor encephalitis associated with ovarian teratomas, a syndrome marked by psychiatric changes, seizures, and autonomic instability that improves with tumor removal and immunotherapy. This is followed by dermatomyositis as a paraneoplastic marker for ovarian carcinoma, with its characteristic rashes, muscle weakness, and high malignancy risk. Next, we cover myasthenia gravis linked to thymoma, emphasizing fluctuating ocular and bulbar symptoms, diagnostic testing, and the need for thymectomy in appropriate cases. Finally, we discuss Trousseau syndrome and nonbacterial thrombotic endocarditis (NBTE) in pancreatic adenocarcinoma, where migratory thrombophlebitis and unexplained clots should raise suspicion for underlying malignancy. We conclude with a rapid wrap-up of high-yield associations: Small-cell lung cancer: SIADH, ectopic ACTH, LEMSSquamous cancers: PTHrP hypercalcemiaOvarian teratoma: Anti-NMDA encephalitisThymoma: Myasthenia gravisPancreatic adenocarcinoma: Trousseau syndrome and NBTEEnjoy the podcast, and please support us below!

In this episode of the Ninja Nerd Podcast, Zach and Rob guide you through diagnosing, staging, and management of gynecological cancers using five high-yield, case-based discussions. We start with a 58-year-old postmenopausal woman presenting with abdominal bloating, early satiety, and weight loss. The workup, including pelvic exam, transvaginal ultrasound, and CA-125 testing, reveals advanced epithelial ovarian carcinoma with omental caking. We walk through the surgical and chemotherapeutic strategies for both confined and advanced disease, plus the role of PARP inhibitors in BRCA-positive patients, and review complications such as ascites, pleural effusion, and small-bowel obstruction. Next, we cover a 65-year-old woman with postmenopausal bleeding and a thickened endometrial stripe on TVUS. Biopsy confirms type I endometrial adenocarcinoma. We discuss treatment pathways based on stage—from TAH-BSO for early disease to adding radiation or chemotherapy when risk increases—and highlight complications like anemia and pyometra. The third case features a 34-year-old woman with postcoital spotting, HPV-16 positivity, and biopsy-proven invasive cervical carcinoma. We break down management options from conization for CIN 2/3 to radical hysterectomy or concurrent chemoradiation for more extensive disease. Key complications, including hydronephrosis and metastatic spread patterns, are also reviewed. Case four presents a 62-year-old woman with vaginal spotting and malodorous discharge, leading to the diagnosis of primary vaginal squamous carcinoma. We focus on the diagnostic sequence—pelvic exam, biopsy, MRI/PET—and the role of cisplatin-based chemoradiation for localized disease. Finally, we discuss a 72-year-old woman with chronic vulvar pruritus and an ulcerated labial lesion, diagnosed as early invasive vulvar carcinoma. We highlight the importance of biopsy for diagnosis and surgical excision for cure. We close by emphasizing a shared approach across all cases: begin with a broad differential, select targeted diagnostics based on presentation, confirm histology, and let stage and patient factors guide treatment—all while anticipating complications.

Send us a text Ninja Nerds! 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. Let’s get into it, Ninja Nerds!

Send us a text Ninja Nerds! 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.
