O06.01 - Lung cancer risks, beliefs, and healthcare access among the underprivileged (ID 2113)
10:40 - 10:50 | Author(s): J. Blay
- Abstract
- Presentation
Background
One goal of the current French National Cancer Plan is to reduce health inequities in cancer control. In this study, an underprivileged population was investigated to analyze exposure to lung cancer risk factors and health care access in order to highlight ways to improve lung cancer control in that population.Methods
Within the nationwide observational study EDIFICE 3, conducted by phone interviews among a representative sample of 1603 subjects aged between 40 and 75 years old, we used the “EPICES” validated questionnaire to examine the association of underserved status with lung cancer risk factors, beliefs, and health care access.Results
Based on the EPICES score, underserved subjects represented 33% of the sample. These subjects subjectively perceived a higher risk of cancer compared to subjects in the served population (21% vs. 14% respectively, p<0.01). Among people with cancer, underserved subjects have a higher rate of lung cancer (10% of cancers vs. 1%, p<0.05). They also have more cancer risk factors: a high BMI (26.0 vs. 24.8, p<0.01), are active smokers (38% vs. 23%, p<0.01) with a higher consumption of cigarettes (16.0 cigarettes/day vs. 10.1, p<0.01) and for a longer period (29.4 years vs. 26.3, p<0.01), and also practice less sport (42% vs. 77%, p<0.01). They have more comorbidities: on average (2.2 vs. 1.8, p<0.01), at least one (76% vs. 65%, p<0.01), hypertension (24% vs. 19%, p<0.05), cardiovascular disease (13% vs. 9%, p<0.05) and respiratory disease (13% vs. 7%, p<0.01). Access to healthcare is not an issue (consultations with a general practitioner are more frequent for the underserved group: 5.4 vs. 3.7 per year, p<0.01). They trust the national health system less (an average score from 1 to 10; 6.0 vs. 6.3, p <0.05). However, 85% of underserved subjects think that lung cancer can be efficiently screened vs. 78% of the served population (p<0.01).Conclusion
In order to reduce inequities in lung cancer control, the effort of upstream interventions should be focused on prevention, as healthcare access does not discriminate. Underserved subjects have a high level of trust in lung cancer screening but a riskier behavior in terms of smoking. This constitutes new targets for specific communication campaigns and Health authorities’ interventions.Only Members that have purchased this event or have registered via an access code will be able to view this content.

P3.14-001 - Assessing the role of chemotherapy for solitary fibrous tumors of the pleura in a routine practice setting (ID 306)
09:30 - 09:30 | Author(s): J. Blay
- Abstract
Background
Solitary Fibrous Tumors of the Pleura (SFTP) refer as to a heterogeneous group of mesenchymal malignancies with various anatomic and histologic features. Upfront surgical resection is the standard approach, but the outcome of patients is unpredictable. Recurrences may be aggressive and difficult to treat.The most widely accepted staging system has been proposed by De Perrot et al., and is based on the anatomy of the tumor implantation (sessile/pedunculated), and the presence of histologic signs of aggressiveness, including cellularity with crowding and overlapping of nuclei, cellular pleomorphism, high mitotic count, necrosis, or stromal/vascular invasion. Given the rarity of the tumor, limited evidence is available about the role and the modalities of perioperative and definite chemotherapy for SFTP.Methods
Multicenter retrospective study of patients (pts) with histologically-proven SFTP with complete follow-up from surgical diagnostic to tumor recurrence and death.Results
68 pts (28 males/40 females) were included. Median age at diagnosis was 62 year-old. Tumor stage according to the De Perrot system was 0/I for 29 pts, II for 23 pts, III for 7 pts, and IV for 4 pts. Adjuvant chemotherapy was given to 7 patients, mostly with stage III/IV SFTP, consisting of doxorubicin-based regimen. Recurrence rate and median time-to-progression (TTP) after surgery were 3%, 52%, 71%, and 75% (p<0.001), and 107, 70, 29, 11 months (p=0.006) for stage 0/I, II, III, and IV tumors, respectively. Besides tumor stage, predictors of shorter TTP were incomplete resection (p<0.001) and a higher number of histologic signs of malignancy (p=0.009). At time of tumor recurrence, 12 pts received chemotherapy. Highest disease control rates were observed with trabectedine (7/9 pts; Disease Control Rate (DCR): 78%; median TTP: 3,4 months), and gemcitabine-dacarbazine combination (2/3 pts, DCR: 66%; median TTP: 1,9 months). Median overall survival of the whole cohort was 56 months.Conclusion
This study 1) confirms the prognostic value of the De Perrot staging system, 2) indicates a high recurrence rate in patients with stage II tumors, for which perioperative chemotherapy may be considered, and 3) suggests an interest for trabectedine in the setting of recurrent tumors. Besides clinical data, further molecular characterization, including recently identified specific gene fusions, may help to better predict the outcome of patients with SFTP.
