Q

Pathophysiology

A

Chronic exposure of epithelial cells to carcinogens results in chronic inflammation that can induce genetic and cytologic changes

Q

Mutations

A

EGFR–> sensitivity to TKI
-More common in females, Asians, and non-smokers

KRAS–> resistance to TKI
-Exclusive to smokers

ALK: more common in younger, andenocarinoma, and no/light smokers

ROS-1: more common in younger, adenocarcinoma, and no/light smokers

BRAF V600E: exclusive to current or former smokers

PDL-1: less common with EGFR, ALK, ROS-1

Screening

A

Spiral CT scan–> high risk only

55-74, 30-year pack history of smoking, current smoker or quit in past 15 years, good health, and willing to have curative lung surgery

False positives, multiple radiologists

Q

SCLC Limited stage treatment

A

Radiation + combination chemotherapy

EC: Cisplatin/Carboplatin + Etoposide every 21 days for 4-6 cycles

Radiation is daily (Mon-Fri) for 6-7 weeks

Q

SCLC Extensive stage treatment

A

Combination chemotherapy

Carboplatin + Etoposide + Atezolizumab every 21 x 4 cycles
Carboplatin + Etoposide + Durvalumab every 21 days x 4 cycles

Prophylactic cranial radiation:
If symptomatic: whole brain radiation prior to chemo
If asymptomatic: whole brain radiation after chemo

Maintenance chemo: Atezolizumab or Durvalumab until patient progresses or toxicities

If patient has progressed–> Pembrolizumab regardless of PDL-1 status

17
Q

NSCLC

A

Surgery is the most efficacious treatment of NSCLC

Radiation may be used in early-stage when surgery is not able

18
Q

NSCLC treatment (resectable)

A

Neoadjuvant chemo–> tumor > 4 cm or lymph node positive
-Platinum doublet + nivolumab x 3-4 cycles

Surgery

Adjuvant chemo
Non-squamous: Cisplatin + Pemetrexed every 21 days x 4 cycles
Squamous: Cisplatin + Gemcitabine every 21 days x 4 cycles
Cisplatin + Docetaxel every 21 days x 4 cycles

Targeted therapies after chemo
Early stage + ALK: Alectinib x 24 hours
Early stage + EGFR: Osimertinib x 3 years
Early stage + High risk + no mutation + PDL1 > 1%: Atezolizumab or Pembrolizumab

19
Q

NSCLC treatment (unresectable)

A

Radiation
Chemotherapy

Non-squamous
Cisplatin + Pemetrexed every 21 days x 3
Carboplatin + Pemetrexed every 21 days x 4

Squamous
Cisplatin + Etoposide
Carboplatin + Pacletaxel

Targeted therapies after chemo
Durvalumab x 1 year
Osimertinib until disease progression
If unable for surgery, chemo, or radiation
PDL1 > 1%–> pembrolizumab

20
Q

Adenocarcinoma (metastatic) NO MUTATION

A

Check PDL1 status
> 1-49%
1st line: Pembrolizumab +/- chemo

> 50%
1st line: Pembrolizumab +/- chemo
Atezolizumab
Cemiplimab +/- chemo

Negative:
1st line: Pembrolizumab/Atezolizumab + chemo

Chemo: Carboplatin + Pemetrexed

21
Q

Adenocarcinoma (metastatic) MUTATION

A

EGFR (exon 19 deletion or exon 21 sub)
Osimertinib

BRAF
Dabrafenib + Treametinib

KRAS G12C
Sotorasib

22
Q

Squamous

A

Check PDL-1 Status + Performance status

If not contraindications to immunotherapy
Pembrolizumab +/- chemo x 4 cycles

If contraindication to immunotherapy
Carboplatin + Paclitaxel/Docetaxel/Gemcitabine x cycles
