Lung Cancer Flashcards
What is important to know about the cases and the deaths related to Lung Cancer?
- 2nd most common
- MOST common cause of death
What is the main risk factor that affects Lung Cancer?
- SMOKING: can be basically preventable
- 85-90% of Lung Cancer is from Smoking
What are some of the other risk factors for Lung Cancer?
- RISK decrease after smoking cessation
- Heavy Metals
-?
What is the etiology of Lung Cancer?
- The Chronic exposure of carcinogens causing inflammation causing genetic changes = carcinogenesis
What are some of the mutations that are associated with Lung Cancer?
- EGFR [10-15%; common in AA & less in Asian; T790M]
- K-RAS [10-30% shorter survival; SMOKERS]
- ALK [4-8%; no/light smokers; young]
- ROS-1 [1%; never smoked]
- BRAF [1-2%; test in 1st line metastatic NSCLC]
- PD-L1 [early stage & metastatic]
What are the two histologic classifications for Lung Cancer?
- NSCLC: adenocarcinoma [50% & non-smoker], Squamous [30%], Large Cell [5%]
- SCLC: Small Cell [15% & Smokers]
What are some of the main differences between NSCLC & SCLC in Lung Cancer?
- SCLC: Smoking, Rapid Growth, HIGHLY sensitive to radiation & chemo
- NSCLC: Slow growth MOD sensitive to radiation, Slight sensitive to chemo
What are the two stages in SCLC?
- Limited & Extensive
Within SCLC, is surgery generally an option?
- NO; Radation and Chemo is
What is important to know about Limited Stage SCLC?
- CUREATIVE intent
- Survival ~12w
- Combined Modailty: Rads + Chemo
- NEED prophylactic cranial Rads
What are some of the regimens that are used for Limited Stage SCLC?
- EP: Cisplatin + Etoposide
- EC: Carboplatin + Etoposide
[Cisplatin < Carboplatin]
What is important to know about Extensive Stage in SCLC?
- RARELY CURABLE
- Survival ~6w
- Platinum Chemo WITHOUT Rads
What are some of the chemos that are used in Extensive Stage SCLC?
- Cisplatin or Carboplatin x4
[Etoposide or Irinotecan]
Should brain radiation by used in Extensive Stage SCLC?
- Yes, if metastases
- Symptomatic = Rads before Chemo
- Asymptomatic = Rads after Chemo
What are some of the Immunotherapies that can be used in Extensive Stage SCLC?
- Atezolizumab + Carboplatin + Etoposide [IMpower133 trail]
- Durvalumab + Carboplatin + Etoposide [CASPIAN trial]
- Durvalumab + Cisplatin + Etoposide
What are some of the complications of therapy for SCLC?
- Platinum drugs = Nephrotoxicity & Neurotoxicity
- Rads = Fatigue, Cardio issues
What is important to know about PD-1 Inhibitors in SCLC?
- Pembrolizumab: for patients that have progressed on or after platinum regardless of status
In Limited or Extensive SCLC, should radiation be give concurrently with chemo?
- Limited: yes; given with cisplatin
- Extensive: ?
