Bladder cancer can be divided into two ✌️subtypes:
1) Non-muscle invasive: encompasses in-situ and localized disease➡️5-yr OS >70%
2) Muscle invasive: encompasses regional or metastatic disease➡️5-yr OS dismal especially for metastatic disease 😔

(1/10) 71 yo F with HTN and ESRD on HD presents to the ED w/ fever 🌡 + back pain, 🧫 BCx + Clostridium septicum. Which test should be considered? 🧐
(2/10) Clostridium septicum [motile, gram +, anaerobic, spore-forming rod] is rare in the GI tract. In colorectal tumor: anaerobic glycolysis = acidic and hypoxic environment ↑ C. septicum spore germination + tumors break down mucosal barrier and ↑ C. septicum blood entry
(3/10) Infxn mortality rates are high (60-79%)
Early diagnosis🩸and aggressive treatment💊of C. septicum are essential.
Colonoscopy is recommended to evaluate for malignancy. What is another gram + organism associated with colon CA?

💡Lung, breast, and lymphoma are the most common causes💡
Query of the pleural fluid with the use of the Lights criteria will help to determine the etiology (transudative or exudative)
Exudative=malignant OR infection
One of the criteria is a serum protein ratio >0.5

So, how does a vaccine for MYCOBACTERIUM work for bladder cancer!?🤨(dont worry, I was making the same confused face you are! Let me explain it to you!)
BCG=attenuated live strain of Mycobacterium🦠 bovis (which interestingly is related to the bacteria that causes tuberculosis)

It is administered by DIRECT instillation into the bladder and the mycobacterium outer membrane binds to a substance (Fibronectin) that is ALSO found within the urothelium.
Why do some pts with renal cell carcinoma present w/ polycythemia🩸vs others w/anemia🤔?
1/ Erythropoietin (EPO)➡️glycoprotein that induces differentiation of erythrocytes in the bone marrow to promote RBC production➡️produced in the KIDNEY

In RCC➡️EPO is produced ectopically by RCC tumor cells causing abnormalities in RBC production
🧐In fact‼️ ectopic EPO occurs in 66% of RCC pts!
Despite high concentrations of EPO➡️Anemia (⬇️RBC) is common due to poor nutrition🍎, hematuria🩸 or ineffective erythropoiesis🛑

PART 3! If you’re not sold on moderately intensive chemo, outcomes with HMA +/- ven also rival outcomes with CPX-351 in sAML. One could argue the control group in the CPX-351 paper should have been hypomethylating agent-based regimens!
CR/CRi rates with 10-d decitabine are consistently >50%, irrespective of sAML, age, and cytogenetics. Median OS in Blum, PNAS 2010 ~13 months. pnas.org/content/107/16…
Whether venetoclax adds anything to this remains to be seen. In the phase I/II study of HMA+ven, CR/CRi in elderly sAML was 67%, median OS NR. Wait for the phase III before you make any conclusions #oncstewardship #anothertweetorial? ncbi.nlm.nih.gov/pubmed/30361262
