How Can We Improve

Lung Cancer Survival UCSFCRMCCCC

Future Directions

1. How to Beat the Survival Time Clock

Stage 5-Yr Survival

2. Decoding The Cancer Gene

5-Year Survival in Lung Cancer is 17%

Lung Cancer Kills More People Than Breast Cancer, Colon Cancer and Prostate Cancer Combined

These data have not changed in the past 15 years

SEER Cancer Statistics Review, NCI.

Lung Cancer is the Leading Cause of Cancer Deaths

SEER Cancer Statistics Review, NCI,

Lung Cancer for 2014

NCI, Cancer Statistics

Prevalence and mortality continue to remain high in Lung Cancer 215,000 are newly diagnosed and 158,000 die of lung cancer

each year

Smoking and Gender Variability In Prevalence of Lung Cancer

From 1974-1994: Prevalence of Lung Cancer in women Increased by 150%;

Death Rates Increased by 600%.

Cigarette Ad 1968 Target women to smokeYou've come a long way, baby

Lung Cancer Prevalence

Tobacco Control Cancer in Men and in cancer in Women

Women are 1.5 times more likely to develop lung cancer than men with same amount of smoking

Early Stage Lung Cancer is Asymptomatic. Therefore Diagnosis is delayed When symptoms occur, its too late

Why is Survival Poor in Lung Cancer

Continued Smoking increases the Risk for Cancer Continued Smoking Decreases response to Therapy “EARLY DIAGNOSIS” improves Lung Cancer survival; however, Early Diagnosis is difficult.

Why is Survival Poor in Lung Cancer

Nicotine Enhances Tumor

Angiogenesis,Tumor Growth

Despite multimillion dollar research on therapy, survival in lung cancer is 17%

“EARLY DIAGNOSIS” is the ONLY factor that improves survival in Lung Cancer. However, the progress is slow.

Lung Cancer is a Preventable Disease

Federal Tax

Nearly 85% Of Cancer Occur Secondary To Smoking

Smoking Cessation Reduces Lung Cancer Risk

Smoking CessationRisk

Prevention: Smoking Cessation: Start Early

90% of Smokers Begin Before Age 1810% of high school kids & 3% of middle school kids smoke Educate Adults and Kids about bad effects of smokingEvery day over 700 kids become regular daily smokers.

We Run a Anti-Smoking Education Program for Schools

Other Smoke

Cigars, Smokeless Tobacco, Chew Tobacco: Are equally harmful

Electronic Cigarettes: Contain Nicotine, which is a carcinogen & Addicting substance

Studies show that E-Cigarettes DO NOT help in Quitting

Electronic Cigarettes Change Gene Expression In Lung Epithelium Similar to Tobacco Smoke

S. J. Park et al. Clin. Cancer Res. 20, B16; 2014).

Do Electronic Cigarettes Cause Cancer?

E-Cigarettes First moved into American market in 2007

Became popular in 2010

Target Year2027

Dedicated Smoking Cessation Program At CRMC – UCSF Fresno

Most Critical Question is –

It’s Abnormal, What do I do Now?????

Any MD can identify High Risk Patients and can order Chest CTs

Diagnosis is particularly challenging in Endemic Cocci Area

Personalized Treatment Approach

Has been shown to be very effective

The Digital Future of Molecular Medicine

It is based on decoding of the human gene Use molecular biology technology to

advanced therapy in cancer and diabetes. Diseases are not homogenous

Drugs, Surgery, Radiation, Vaccines, HormonesAdd Targeted Personalized Rx Approach

PD1PDL1

Molecular Targets for Therapy(FDA-approved therapies & Clinical Trials)

Personalized Treatment Approach

N Engl J Med 2013; 368:2385-2394

Personalized Treatment ApproachPD1 and PDL1 Targeted Therapy

Molecular Targets for Therapy(FDA-approved therapies for solid tumors)

Extracellular targetsEGFR/HER (cetuximab, panitumumab, trastuzumab)VEGF (bevacizumab)HER2 (trastuzumab)Intracellular targetsEGFR (erlotinib)VEGFR (sorafenib, sunitinib)mTOR (temsirolimus)PDGFR (sorafenib, sunitinib)RAF/MAP kinase (sorafenib)HER2/EGFR1 (lapatinib)C-kit (sunitinib)

EGFR and KRAS mutations in NSCLC are mutually exclusive

NSCLC patients with EGFR mutations respond well to EGFR-Tyrosin Kinase Inhibitors (EGFR-TKIs)

NSCLC patients with KRAS mutations may be less likely to respond to EGFR-TKIs

EML4-ALK NSCLC: A unique subset of NSCLC who respond effectively to ALK inhibitors

Immunotherapy for Lung CancerTherapeutic Vaccines for Lung Cancer

Monoclonal Antibodies Bavituximab, (SUNRISE; NCT01999673). Rilotumumab, (NCT02154490)

Immune Checkpoint Inhibitors: CTLA-4 antibodies Ipilimumab (Yervoy™), targets the CTLA-4 a Tremelimumab (NCT01655888 and NCT01649024)

PD-1 antibodies Nivolumab (BMS-936558) (NCT01673867) MK-3475 phase III (NCT01905657).

PD-L1 antibodies MPDL3280A (NCT01846416) MEDI4736 (NCT01693562), (NCT02154490)

Therapeutic Vaccines: MAGE-3 and NY-ESO-1 Antigen-based immunotherapies Belagenpumatucel-L (NCT00676507) Tergenpumatucel-L (NCT01774578). GV1001 targets hTERT (telomerase ) TG4010 (NCT01383148) INGN, vaccine targets p53 (NCT01383148) A vaccine targeting the WT1 (NCT01265433) CV9202 RNActive®-derived cancer vaccine

Adoptive T Cell Transfer

Genetically Engineered T cells – target CEA (in 30% of NSCLC).Genetically Engineered T cells – target NY-ESO-1 (NCT00670748)

Poor Prognostic Factors

Presence of pulmonary symptoms Large tumor size (>3 cm) Non-squamous histology Poorly Differentiated Metastases to multiple lymph nodes within a

TNM-defined nodal stations Vascular invasion.

The Digital Future of Molecular MedicineIs a Bright Ray of Hope

Our goal is to examine mutations by molecular studies in all patients to direct personalized treatment.

Very Expensive Mutation Genetic Tests, Not frequently Covered by Insurances

Limitations

Early Diagnosis improves survival in Lung CancerCT Screening can saves lives in very selected patients It is expensive; Health care cost is very high Smoking cessation is important in reducing cancer riskPET Scan are False Positive in our Cocci areaAccess to Organized Multidisciplinary Lung Nodule

Program is essential for early diagnosis & managementMolecular marker Targeted Therapy is the futurePrevention, Early Diagnosis and Early Treatment can

help improve survival in lung cancer.
