of the tumour came to T4N2M1a according to 8th edition of IASLC TNM<br />

classification for lung cancer. Her performance status improved to ECOG 2.<br />

She was given cisplatin and etoposide in addition to brain radiation therapy.<br />

Conclusion: The second primary malignancy refers to a different type of<br />

cancer in a person who has survived an earlier cancer. There are series of nonsmall<br />

cell lung cancer (NSCLC) reported as second primary after breast cancer.<br />

To our knowledge, this is the first case presented as small cell lung cancer as<br />

second malignancies in lung in a fully treated breast cancer patient. This may<br />

be related risk of second malignancies associated with radiotherapy exposure<br />

to lung applied for breast cancer or due to adjuvant treatment as in this case.<br />

P1.07-055 INTRODUCING THE US NATIONAL CANCER INSTITUTE’S<br />

SMALL CELL LUNG CANCER CONSORTIUM<br />

Background: Small cell lung cancer (SCLC) remains a major clinical challenge,<br />

however recent discoveries and early positive signals in clinical trials are<br />

promising more optimistic outcomes for patients with this disease. The<br />

United States National Cancer Institute (NCI) launched in December 2015<br />

a series of solicitations for grant applications with the goal to establish a<br />

SCLC consortium. The Consortium will address five strategic priority areas<br />

established by an international group of experts and the NCI. These areas<br />

are: 1. Better research tools for the Study of SCLC, 2. Comprehensive genomic<br />

profiling of SCLC, 3. New diagnostic and prevention approaches for SCLC, 4.<br />

Therapeutic development efforts, and 5. Mechanisms underlying both high<br />

rate of initial response and rapid emergence of drug and radiation resistance.<br />

The initiative for early detection and prevention of SCLC is now open for<br />

potential applicants through 2017 (PAR-16-51); applications for therapy and<br />

mechanism of resistance projects can be submitted through 2018 (PAR-16-49).<br />

Methods: Section not applicable Results: (Note: The first round of application<br />

was reviewed right before the IASLC abstract submission deadline, funding<br />

decisions will be made in early November 2016, so by the time of the November<br />

11 deadline for the poster submission we will be able to include the first funded<br />

projects in the consortium in the abstract and in the poster.) Conclusion:<br />

Section not applicable<br />

Keywords: Therapy, Early Detection, small cell lung cancer, drug resistance<br />

P1.08-001 LOG ODDS AS A NOVEL PROGNOSTIC INDICATOR<br />

SUPERIOR TO THE NUMBER-BASED AND RATIO-BASED CATEGORY<br />

FOR NON-SMALL CELL LUNG CANCER<br />

Poland<br />

Background: The paper aimed to compare the efficacy of log odds (LODDS)<br />

compared to a classification based on the number of positive lymph<br />

nodes (pN) and lymph node ratio (LNR). Methods: Material was collected<br />

retrospectively from an online survey-based database of the Polish Lung<br />

Cancer Group and included a group of 17369 patients who received radical<br />

surgical treatment (R0) due to lung cancer. The follow-up period was between<br />

11.4 and 66.0 months (median 30.1 months). Results: In the whole group the<br />

median survival for N0, N1 and N2 was 76.1, 41.7 and 24.2 months, respectively.<br />

The median survival for individual LODDS categories (-6,-4], (-4,-3], (-3,-2],<br />

(-2,-1], (-1,0], (0,1] and (1,2] was 76.5, 76.3, 71.7, 45.4, 25.0, 19.1 and 17.7 months,<br />

respectively. The median survival for LNR in individual categories (0), (0,0.25],<br />

(0.25,05], (0.5,075] and (0.75,1.0] was 75.6, 40.3, 24.1, 18.8 and 16.4 months,<br />

respectively. When comparing LODDS and LNR significant heterogeneity<br />

can be seen that is especially visible in categories (0), (0,0.25] LNR, where 4<br />

LODDS categories were distinguished. A multi-variant analysis demonstrated<br />

that each LODDS category is an independent prognostic factor: (-4,-3] (HR =<br />

0.982; 95% CI 0.867-1.112; P = 0.775), (-3,-2] (HR = 1.114; 95% CI 0.984-1.262; P =<br />

0.089), (-2,-1] (HR = 1.241; 95% CI 1.080-1.425; P = 0.002), (-1,0] (HR = 1.617; 95%<br />

CI 1.385-1.887; P < 0.0001), (0,1] (HR = 1.918; 95% CI 1.579-2.329; P < 0.0001)<br />

and (1,2] (HR = 2.016; 95% CI 1.579-2.573; P < 0.0001). Conclusion: Based on<br />

LODDS it is possible to discriminate patients with regard to lung cancer stage<br />

more effectively compared to pN and LNR classification, and it is also a better<br />

classification system. Therefore, a new system of lung cancer classification<br />

based on LODDS should be considered.<br />

Background: The status of intraoperative pleural lavage cytology (PLC) has<br />

been reported to be a predictive factor of recurrence in resected non-small<br />

cell lung cancer (NSCLC). However, prognostic significance of PLC remains<br />

unclear and it has not been included in the TNM classification. Furthermore,<br />

the appropriate timing to perform PLC, before lung resection (pre-PLC) or<br />

after lung resection (post-PLC), is not evident. Methods: Of 627 consecutive<br />

patients with NSCLC who underwent complete resection (segmentectomy<br />

or more) in Tottori University Hospital from January 2004 to December 2013,<br />

615 patients who were performed both pre-PLC and post-PLC were enrolled<br />

in present study. Patients were divided into four groups, negative pre-PLC /<br />

negative post-PLC (Group A), positive pre-PLC / negative post-PLC (Group B),<br />

negative pre-PLC / positive post-PLC (Group C), and positive pre-PLC / positive<br />

post-PLC (Group D). Then differences in recurrence free survival (RFS) and<br />

disease specific survival (DSS) among each groups were analyzed by log-rank<br />

test. Moreover, PLC status as a prognostic factor for RFS and DSS were<br />

analyzed using univariate and multivariate Cox regression models. Results:<br />

There were 573 patients in Group A, 11 in Group B, 14 in Group C, and 17 in<br />

Group D, respectively. Survival analysis revealed significant differences in not<br />

only RFS but also DSS between Group A and Group B (log-rank test, p
