Backgroud: Lung cancer is the leading cause of cancer deaths in the world.<br />

For patients with advanced non-small cell lung cancer (NSCLC), survival<br />

prognosis is very poor with chemotherapy and radiotherapy. However, the<br />

possibility of occult metastases may lead to discrepancy between clinical<br />

and pathologic staging and underestimation of the disease severity, and<br />

how to individualized choose the appropriate patients with locally advanced<br />

non-small cell lung cancer for surgery is controversies. In this study, we<br />

presented here the Chinese experience: individual precision surgery for locally<br />

advanced non-small cell lung cancer based on molecular staging. Methods:<br />

We developed several molecular biomarkers and molecular models from<br />

Circulation Tumor Cell (CTC ) detection, mi-RNA chip, Gene Chip from 1990.<br />

We used these Molecular biomarkers and molecular models for molecular<br />

staging, molecular typing, choosing indication of operation and neoadjuvant<br />

chemotherapy, predicting postoperative recurrence and prognosis of locally<br />

advanced non-small cell lung cancer. Results: We developed two molecular<br />

staging model for individualized surgical treatment for locally advanced<br />

non-small cell lung cancer involving heart, great vessels or both. 3308 patients<br />

with locally advanced non-small cell lung cancer were underwent completely<br />

resection of the cancer in the three medical center. The 1-, 3-, 5- and 10 year<br />

survival rate were 74.5%,62.3%,31.5% and 22.9%, respectively. We used our<br />

molecular staging model for neoadjuvant chemotherapy for 665 patients<br />

with locally advanced lung cancer. The 1-, 3-, 5- and 10-year survival rate were<br />

79.35%, 51.46%, 27.39% and 20.34% of the patients, respectively. We used our<br />

molecular model to divide N2 lung cancer into invasive N2 and Non-invasive<br />

N2 group. We used our molecular models adenocarcinoma and squamous<br />

carcinoma to divide T4 lung cancer into high recurrence and low recurrence<br />

groups, and help postoperative adjuvant therapy. Conclusion: Our molecular<br />

staging and typing models can help us carry out individual precision surgery,<br />

predicting prognosis and cancer recurrence of the cancer for locally advancer<br />

no-small cell lung cancer. Keywords: non-small cell lung cancer, individual<br />

precision surgery, Molecular staging, molecular typing<br />

for 1st line chemotherapy (CT). ORR was 20-25% for platinum-duplets,<br />

1-year survival – 27,5-37,5 month. The 1-year survival showed best results<br />

in absolute figures with paclitaxel and platinum compounds in SCC and<br />

gemcitabine and platinum compounds in non-SCC, but the value was not<br />

statistically significant neither for 1-year nor for median survival. For SCLC<br />

new combination with irinotecan and platinum compound showed ORR –<br />

55,1% and stabilization of disease in 24,3% of pts. Conclusions: Nowadays the<br />

treatment approaches to lung cancer in Russia depends from morphological<br />

type of tumors, IGC results and needs further investigations. Keywords:<br />

NSCLC, NET, Squamous cell carcinoma, Adenocarcinoma, lung cancer<br />

SC17.02 LUNG CANCER IN CHINA: CHALLENGES AND PERSPECTIVES<br />

Lung cancer is still the leading cause of cancer death in China. The estimated<br />

new lung cancer cases and deaths were 733,300 and 610,200 in 2015,<br />

respectively. Non-small cell lung cancer (NSCLC) remains the predominant<br />

form of the disease in China, with majority of patients being diagnosed at<br />

advanced stages. Thus this presentation will focus on advanced stage NSCLC.<br />

Current treatment strategy The current treatment algorithm for wild-type<br />

non-squamous and squamous NSCLC were shown in Figure 1 and 2,<br />

respectively.<br />

SC17.01 LUNG CANCER IN RUSSIA: CHALLENGES AND<br />

PERSPECTIVES<br />

Background: Cancer is set to become a major cause of morbidity and<br />

mortality in coming decade in every region of the world. Methods: The<br />

mortality, morbidity and treatment variants in Russia were evaluated.<br />

Results: The incidence of lung cancer morbidity in Russia in 2014 numbered<br />

57 685, mortality – 49 730. Standardized index incidence rate demonstrates<br />

improvement of men since year 2009. It was 55,0 on 100 000 population in<br />

2009; 49,15 in 2013 and 49,0 in 2014. It means a 10,9% decrease since 2009 to<br />

2014. It takes stable first place in men.<br />

In women the same years showed different values: 7,0; 7,17; 7,3 at 2009, 2013<br />

and 2014 years respectively, that means + 4,3%. It takes 10-12 places of all<br />

malignant diseases among women. Among men lung cancer is on the first<br />

place (26,6%) in mortality rates. A non-interventional, prospective cohort<br />

study included 838 patients, average age 58,7; male – 78,4%; female – 21,6%,<br />

smokers – 26,5%; ex-smokers – 24,1%, current smokers – 49,4%. Disease stages<br />

at diagnosis were: stage I-II – 36,8%; stage III – 37,8%; stage IV – 25,4%. It was<br />

squamous-cell carcinoma – 54,3%; adenocarcinoma – 31%; BAR – 6,4%; LCC –<br />

2,9%, adenosquamous carcinoma – 2,3%, other – 3,1%.<br />

Proportion of EGFR positive tumors constitutes 10,1% (85/838) pts. Surgery<br />

was performed for 393 pts (46,9%). Radiotherapy was administered to 145<br />

pts (17,8%). 370 pts (44,2%) underwent first-line CT and 96 (11,8%) – secondline.<br />

The treatment depends on the morphology type of the tumor. We<br />

consider four main types NSCLC (AdenoCa and SCC), LCLC and NETs. NETs<br />

group included typical and atypical carcinoids, LCNEC, SCLC. We participated<br />

in 53 different multicenter international trials in lung cancer, including 930<br />

patients. Outside of these protocols we analyzed 567 pts with advanced<br />

NSCLC: 255 pts with squamous cell cancer (SCC) and 250 pts with non-SCC<br />

Figure 2. Treatment algorithm for advanced squamous NSCLC<br />

For patients with activating EGFR mutations, EGFR-TKIs therapy will<br />

be used as front-line therapy. Commercial available EGFR-TKIs in China<br />

include Gefitinib, Erlotinib and Icotinib. For patients harbouring an ALK<br />

rearrangement, crizotinib will also be considered as first-line treatment.<br />

When failed from EGFR-TKIs or ALK-Inhibitor therapy, patients will be<br />

treated according to clinical model of disease progression. For patients<br />

with asymptomatic progression, continuing EGFR-TKIs or ALK-Inhibitor<br />

is recommended. For patients with local progression, EGFR-TKIs or ALK-<br />

Inhibitor will also be continued with additional local therapy such as whole<br />

brain radiation. However, for patients with aggressive progression, EGFR-TKIs<br />

or ALK-Inhibitor will be substituted by chemotherapy. Unfortunately, it is<br />

difficult to overcome drug resistance according to molecular mechanism<br />

because novel agents such as Osimertinib and Alectinib haven’t been<br />

approved by Chinese FDA. Challenge and perspective 1. Genetic alterations<br />

assays Genetic alterations are frequent in Chinese NSCLC patients.<br />

According to PIONEER study (NCT01185314), which is a prospective molecular<br />
