Lung Cancer Stages and Survival
NCI, 2015.
NSCLC: Breakdown by Subtype

Adenocarcinoma (44%)
- Most common type of
NSCLC
- Most common type in
nonsmokers

Large cell carcinoma (3%)

Other (23%)

Squamous (26%)
– Usually more centralized
– More frequently associated with
significant cough and hemoptysis
Houston et al, 2014.
NSCLC: Molecular Biomarkers

Most commonly found in adenocarcinoma, rare
in squamous cell carcinoma
 Consider testing in squamous cell for never
smokers or in mixed adenocarcinoma and
squamous
 Three most common mutations in NSCLC:
– KRAS mutation
– EGFR mutation
– EML4-ALK gene translocation

EGFR and EML4-ALK most common in patients
with never/minimal smoking history
Hirsch, 2012; NCCN, 2015b.
Molecular Abnormalities in NSCLC
With Current Implications
EGFR




KRAS




EML4-ALK
 Incidence of EML4-ALK translocation: 2-7%
 Estimated prevalence of EML4-ALK in lung cancer: 6,000 pts/yr US; up to 40,000
pts/yr globally
 Most EML4-ALK fusion events observed in lung adenocarcinoma specimens vs.
squamous or small cell histologies
 EML4-ALK almost never coexists with EGFR, HER2, or KRAS mutations,
indicating it is a distinct disease subtype
Transmembrane receptor
Detectable in about 80-85% of patients
Level of expression varies widely
Mutations in this domain (10-15% of pts) result in activation of the tyrosine kinase
domain with significantly better response to erlotinib or gefitinib or afatinib
 Mutations: highest incidence in never smokers, adenocarcinoma, women, and
patients with Asian ethnicity
25% of North American population
Associated with smoking and resistance to tyrosine kinase inhibitors (TKIs)
There are different types of KRAS mutations
Therapy with drugs other than erlotinib should be considered first
NCCN, 2015b; Langer et al, 2010.
Molecular Abnormalities of Interest
ROS 1 rearrangement




T790M
 EGFR resistance mutation
 >60% of patients develop it after treatment
 Drugs in clinical trials: CO-1686, AZD9291
BRAF
 4% NSCLC
 Most common is V600E
 Decreased PFS from platinum-based
chemotherapy
 Drugs in clinical trials: dabrafenib
RET
 1-2% NSCLC
 Highly associated with young, never smokers
 Drugs in clinical trials: vandetanib, cabozantinib
1-2% of NSCLC
Detected via FISH test
Sensitive to crizotinib
Usually in younger, never smokers
FISH = fluorescence in situ hybridization; PFS = progression-free survival.
Bergethon et al, 2012; Cardarella et al, 2013; Tsuta et al, 2014.
Why Do Biomarkers Matter?

PFS with standard chemotherapy regimens in NSCLC:
– Pemetrexed/cisplatin: 5 months
– Paclitaxel/carboplatin/bevacizumab: 6 months

PFS with EGFR mutated NSCLC receiving EGFR targeted
therapy:
– Gefitinib: 9.5 months
– Erlotinib: 9.7 months
– Afatinib: 11.0 months

PFS with ALK-positive NSCLC receiving ALK inhibitor:
– Crizotinib: 9.7 months
Camidge et al, 2012; Yang Shih, et al, 2012; Rosell et al, 2012; Fukuoka et al, 2011;
Scagliotti et al, 2008; Sandler et al, 2006.
Patient Factors in Treatment Planning

Patient ECOG PS
– PS is a predictor of survival/tolerating
chemotherapy
– PS 0-1 patients tolerate chemotherapy
best
– PS 2 patients can potentially benefit,
even from doublet chemotherapy;
however, toxicity must be monitored
closely

Comorbidities
– Diabetes
– Heart disease
– Renal disease
ECOG PS = Eastern Cooperative Oncology Group performance status.
Rodriguez & Lilenbaum, 2008.
Patient Factors in Treatment Planning
 Patient
goals for treatment
– Quality of life issues (eg, hair loss)
– Advanced directives
 Demographics
 Social
support
– Involve social worker
– Counseling services
– Nutrition services
 Financial
issues
Supportive Care Paradigms

Both ASCO and NCCN recommend
integration of palliative care into oncology
practice

Early palliative care leads to increase in
overall survival (OS) in patients with
metastatic NSCLC

Increased quality of life, less depressive
symptoms

Improved understanding of diagnosis
– 1/3 patients at diagnosis thought they had
curable disease
– Less likely to receive chemotherapy near
end of life
ASCO = American Society of Clinical Oncology; NCCN = National Comprehensive Cancer Network.
Temel et al, 2011; Temel et al, 2010; Smith et al, 2012; NCCN, 2015b.
Case Study 1:
First-Line Treatment
Mrs. JF: History

68-year-old woman, presented 1 month ago with pain in
her lower back

Initial management with nonsteroidal antiinflamatory drugs
somewhat helpful; however, the pain persisted and an xray of the lower spine was ordered

X-ray did not show bone abnormality but revealed a right
lung mass at the right lung base

Further imaging with positron emission
tomography/computed tomography (PET/CT) revealed a
right lung mass, mediastinal lymphadenopathy, bone
metastases in the lumbar spine, and liver metastases
– X-rays are often negative
Mrs. JF: Diagnostic Evaluation

Treating physician referred the patient to a pulmonologist
for a bronchoscopy with biopsy
– Mediastinal lymph node was positive for NSCLC,
adenocarcinoma histology

Magnetic resonance imaging (MRI) scan of the brain
negative for metastatic disease

Baseline labs within normal limits

Baseline PS 1

What factors important in treatment planning?
Mrs. JF: Treatment Considerations

Molecular analysis: Do you have enough tissue?
What to test for? Which are actionable?

Smoking history?

Comorbidities?

Weight loss, hemoptysis?

Goals of care, palliative care, incurable illness:
Talk to your patient about these important, yet
sensitive topics!
Mrs. JF: Treatment Considerations

Bronchoscopy yielded core biopsy. Tissue was sent for full
molecular analysis. Negative for EGFR, ALK, and ROS1
Patient has a 45-pack-year smoking history, currently trying to
quit
 Patient has hypertension (controlled with medication),
hypercholesterolemia, chronic obstructive pulmonary disease
 No significant weight loss, no hemoptysis
 Understands incurable, no advanced directive, would like to
“fight”
Mrs. JF: Treatment Selection

Standard chemotherapy in biomarker-negative
patient appropriate therapy

Numerous options available for chemotherapy

Platinum based chemotherapy appropriate given
good PS

Is hair loss an issue?

Does she want to enroll in a clinical trial?
NCCN, 2015b.
Mrs. JF: Treatment Selection
 Cisplatin
vs. carboplatin? In US, carboplatin
is often used in frontline therapy
 Which
drug to pair with carboplatin? Toxicity?
– Pemetrexed
– Paclitaxel
– Docetaxel
– nab-paclitaxel
– Gemcitabine
– Vinorelbine

toxicity profiles of different regimens
 Take
histology into account
 Give
patients autonomy to decide
– Do they want treatment?
– If so, which regimen’s toxicity profile is right for
them?
– Comorbidities? Diabetes? Coronary artery
disease? Renal insufficiency?

Case Study 1 Continued:
Maintenance Therapy
Mrs. JF: Post-Induction

After treatment with six cycles of
pemetrexed/carboplatin/bevacizumab, her tumor is
stable

Experienced a 20% reduction in tumor volume after two
cycles, and disease has not worsened since

Overall she has tolerated the regimen with minimal
toxicity

Her options are now:
– Stop chemotherapy, best supportive care, re-scan in 2 months
– Continue with maintenance chemotherapy
Maintenance Therapy

If no disease progression after first-line
chemotherapy, continue the chemotherapy
and/or targeted agent?

We know that in NSCLC continuing platinum
chemotherapy past four to six cycles does not
improve survival, just increases toxicity

However, several drugs have shown
improvement in PFS in the maintenance setting
NCCN, 2015b.
Maintenance Pemetrexed
Both studies showed improvement in OS when either switching to or continuing
with maintenance pemetrexed after first-line induction platinum-based
chemotherapy.


Do patients want a break or wish to continue?

Toxicity profile
– Pemetrexed is chemotherapy: potential for lowering of

– Bevacizumab and erlotinib are targeted agents, with
the potential for hypertension/cardiac toxicity, rash

Case Study 2:
Older Adult With NSCLC
Mr. PD: History

Patient is an 80-year-old fit man who developed
increased shortness of breath and cough during
the past 6 months, though hemoptysis is what
led him to the emergency department

CT scan of the chest revealed a large, central
lung mass as well as adrenal metastases

He is a lifelong cigarette smoker, 1 pack per day

CT-guided needle biopsy reveals squamous cell
NSCLC
Mr. PD: Diagnostic Evaluation
 Brain
MRI scan shows a single brain
metastasis 1.5 cm, for which he undergoes
stereotactic brain radiation
 Patient
presents to oncology clinic to decide
about treatment options for his cancer
 Patient
has a supportive wife and daughter;
he still plays golf once a week and bridge
with his friends on Wednesday nights
Incidence of NSCLC in the US
by Age at Diagnosis
Median age at diagnosis: 70

Mr. PD: Treatment Considerations

Chemotherapy has survival advantage over best
supportive care for the fit elderly
 Patient would like to maintain ability to play golf
and bridge and spend time with grandchildren
 Chemotherapy with platinum-based doublet is
an option for him
 What can we give him that can maintain quality
of life and yet give him chance for increased
survival? Family wants him to pursue treatment

Newest Class of Agents in NSCLC: PD1 Inhibitors

Well tolerated, could be used in elderly given favorable
safety profile
 Nivolumab is only approved agent, second line after
failure of chemotherapy
 Tumors evade immune attack by having the PD-1 ligand
bind to T-cells and inactivate them against the tumor
 PD-1 inhibitors stop this process, thus leaving the tumor
vulnerable to attack
 Other drugs under investigation: pembrolizumab,
MPDL3280A (PD-L1), MEDI4736 (PD-L1), ipilumumab
(CTLA-4), tremelumumab (CTLA-4)

Key Takeaways

Treatment strategies for advanced NSCLC
continue to evolve: maintenance, more
aggressive treatment for elderly patients
 Toxicity profiles can vary significantly depending
on selected agent(s)
 Oncology nurses play an important role in
monitoring for and managing toxicities, as well
as providing patient education
