Results: The mean serum 25(OH)D concentration of 197 cases with lung cancer in<br />
China was 10.63 ± 7.04ng/mL; <strong>the</strong> proportion of vitamin D deficiency was 173/197 in<br />
all patients, 103/112 in adenocarcinoma. and 31/39 in squamous cell carcinoma. The<br />
vitamin D deficiency ratio was higher in adenocarcinoma than in squamous cell<br />
carcinoma, p= 0.043. PGJ2\DFOM can induce OCT4 + BASC to be CCSP-\SP-C +<br />
\OCT4- cell, and <strong>the</strong>n 1,25(OH)2D3 can prevent <strong>the</strong> expression re-recovery of<br />
OCT-4 and CCSP. DAPT significantly lowered CCSP expression in OCT4 + BASC,<br />
and <strong>the</strong>n 1,25(OH)2D3 can make it become OCT4-\SP-C-\CCSP-\SP-B+ cell, which<br />
is a mature AT2-like cell. 1,25(OH)2D3 has no effect on OCT4 + BASC or AT1-like<br />
cell differentiation.<br />
Conclusion: Lung cancer patients are generally lacking vitamin D, and lung<br />
adenocarcinoma patients are more likely to be lacking vitamin D. 1,25(OH)2D3 can<br />
promote lung adenocarcinoma progenitor cell differentiation.<br />

Lung cancer is a major public health problem due to its continued increase. In<br />
2010, <strong>the</strong> French College of General Hospital Respiratory Physicians (CPHG)<br />
performed a prospective multicenter epidemiological study (KBP-2010-CPHG) to<br />
describe <strong>the</strong> baseline characteristics and management of all new cases of primary<br />
lung cancer; to evaluate 1, 4 and 5-year patient survival rates; and to compare<br />
results with those from a similar study performed 10 years ago (KBP-2000-CPHG).<br />
Data were collected on a standardized form for all patients ≥18 years with primary<br />
lung cancer, histologically or cytologically diagnosed between January 1 and<br />
December 31, 2010 and managed in a general hospital. 7,610 patients were enrolled<br />
in 119 centers. 6,083 patients (86.3%) had non-small-cell lung cancer (NSCLC);<br />
among <strong>the</strong>m, 24.4% were female (vs. 16% in 2000; p < .0001). There was no<br />
difference between male and female NSCLC patients regarding age (65.7± 10.9 vs.<br />
64.9± 13.0, p = 0.03). Regarding smoking status, between 2000 and 2010, women<br />
remained more frequently non-smoker compared to men (34.2% vs. 4.7%), less<br />
frequently former smoker (21.3% vs. 46.8%) and showed lower consumption (37.2<br />
vs. 43.7 PY) (p < .0001). However, in 2010, <strong>the</strong> percentage of non-smokers nearly<br />
doubled in men (2.5% vs. 4.7%; p < .0001) whereas it remained stable in female (p<br />
< .32). Regarding tumor characteristics, between 2000 and 2010, <strong>the</strong> percentage of<br />
adenocarcinomas significantly increased in both women (53.4% in 2000 vs. 65.9% in<br />
2010; p < .0001) and men (32.4% vs. 49.4%; p < .0001). However, in 2010, tumors<br />
remained more frequently adenocarcinomas in women than in men (65.9%<br />
vs.49.4%; p < .0001). In addition, in 2010, when explored (48.5% in women vs.<br />
31.0% in men; p < .001), an EGFR mutation was more frequently found in women<br />
than men (20.6% vs. 5.2%; p < .0001), stage IV tumor was more frequent in women<br />
than men (62.4% vs. 56.9%; p = 0.0008), and regarding first-line treatment, 64.5% of<br />
women vs. 61.0% of men (p = .01) received chemo<strong>the</strong>rapy and 13.4% of women vs.<br />
5.7% of men (p < .0001) targeted <strong>the</strong>rapy. In 10 years, percentages of women,<br />
non-smokers among men, and adenocarcinomas in both men and women<br />
increased. However, differences between women and men in baseline and tumor<br />
characteristics persist.<br />

Background: Trastuzumab-associated cardiotoxicity (TAC) has been established in<br />
<strong>the</strong> context of clinical trials. However, when newly registered agents are used in a<br />
broader patient population, <strong>the</strong>ir safety profile does not always mirror that of <strong>the</strong><br />
pivotal trials. Trastuzumab (T) only became available in <strong>the</strong> Brazilian public sector in<br />
2008 and herein we report our off-trial experience so far.<br />
Methods: Retrospective, single center cohort of HER-2 positive breast cancer patients<br />
(pts) treated with (neo)adjuvant chemo<strong>the</strong>rapy and T from July 2008 to March <strong>2012</strong>.<br />
95.3% were treated according to local protocol (11.4% TCH; 83.9% AC-TH). Major<br />
cardiac event (MCE) was defined as a left ventricular ejection fraction (LVEF) drop<br />
of 10% and absolute drop to < 50 % by echocardiogram (ECHO) or as symptomatic<br />
heart failure (HF) regardless of <strong>the</strong> LVEF value or any cardiac event considered<br />
clinically meaningful. A multivariable Cox proportional hazards model was used to<br />
control for o<strong>the</strong>r cardiac risk factors.<br />
Results: 237 women were identified: median age 53 y (27-83), 99.6% ECOG-PS 0-1,<br />
median body mass index 27.4 kg/m 2 (17 – 46), 30.4% had hypertension (HTN), 8.8%<br />
had diabetes mellitus (DM), 5.9% had previous cardiopathy. 54.8% had ER-positive<br />
tumors; 40.7% received neoadjuvant T; most were stage II or III (22.3% and 37.1%).<br />
Median number of ECHO assessments was 2.7 (0-6); 136 pts (57.2%) completed T as<br />
planned. 20.2% had MCE (13.9% discontinued T). 3.8% discontinued T due to<br />
symptomatic HF and 5% for non-cardiac reasons. 41.6% of MCE pts recovered<br />
cardiac function. Median initial LVEF was 64.83 ± 1.5 % (no event) vs 64.81 ± 1.5 %<br />
(MCE) p = 0.26; median 3-month LFVE was 64.67 ± 4 % (no event) vs 56.12 ± 3 %<br />
(MCE) p = 0.0036. HTN, DM, obesity, age, radio<strong>the</strong>rapy, use of anthracycline and<br />
previous cardiopathy were not significantly associated with TAC.<br />
Conclusions: Our results suggest that TAC in our routine practice is slightly higher<br />
than reported in literature (6 to 17%), possibly reflecting selection bias in clinical<br />
trials. Symptomatic TAC was as expected for AC-TH (4%). We failed to identify risk<br />
factors for TAC, possibly due to <strong>the</strong> low number of events. Cardiac function must be<br />
closely monitored during T treatment and careful pt selection is crucial.<br />

Background: Breast cancer in young women (right side). Ninety percent of patients were married and median age at first child<br />
birth was 23 years. Positive family history was elicited in 10 patients. Five patients<br />
presented with synchronous malignancy. The TNM (7th edition) stage distribution was<br />
stage I - 2.5 %, stage II - 30%, stage III - 46.5%, and stage IV - 22%. The median clinical<br />
tumor size was 5.0 cm. Modified radical mastectomy was <strong>the</strong> commonest surgical<br />
procedure and this was done in 83 % of cases. The histopathological analysis showed<br />
94% had infiltrating ductal carcinoma. Thirty percent of tumors were high grade and<br />
70% had pathological node-positive disease. ER/PR and Her2neu positivity was 33% and<br />
29%, respectively. Triple-negative breast cancer (TNBC) constituted 31%. A combination<br />
of anthracyclines and taxanes were used in <strong>the</strong> majority of patients and trastuzumab was<br />
used only in 3 % of cases. With a median follow up of 28 months (non-metastatic<br />
group), 3-year disease-free survival (DFS) and overall survival (OS) was 50% and 60%.<br />
Higher Nodal stage, tumor size (>5 cm), negative hormonal status (triple negative) and<br />
visceral metastasis at baseline predicted poor outcome.<br />
Conclusion: Young women constituted 7.5 % of breast cancer cases. The proportion<br />
of triple negative (nearly one third) was also higher than <strong>the</strong> Western population.<br />
Higher stage and triple negative status results in poorer outcome.<br />

Childhood cancer is curable. Malnutrition poses a major problem amongst Indian<br />
children with around 40% of <strong>the</strong>m suffering from undernourishment and starvation.<br />
It is one of <strong>the</strong> causes of poor outcome and toxicity of cancer patients. This study<br />
will help to highlight <strong>the</strong> close knitted relationship between <strong>the</strong> nutritional status and<br />
its influence on complete remission, disease free survival (DFS) and<br />
chemo<strong>the</strong>rapeutic toxicity. In <strong>the</strong> present study, 500 cancer affected children were<br />
analyzed, who were being treated during a period from Jan, 2007 to Dec, 2011. The<br />
age range was 1-18 years (mean 12.5 years). There was male preponderance.<br />
