      57P - small cell lung cancer: Retrospective review of an institution (ID 508)

      12:30 - 13:00  |  Author(s): C. Oliveira

      • Abstract

      Background:
      Small cell lung cancer (SCLC) account for 10 to 15% of lung cancers. Despite the high rate of response to chemotherapy and radiotherapy, it is characterized by a rapid growth and development of widespread metastases.

      Methods:
      Retrospective review of patients with SCLC with diagnosis between January 2013 and December 2016 in our institution - Portuguese Oncology Center, Porto. Descriptive analysis and survival evaluation by Kaplan-Meier method. Evaluation of differences between survival curves by log rank test.

      Results:
      From the 144 patients included, 115 (79.9%) were male and the mean age was 65 years (range 42-87). The majority of patients had an ECOG PS 0-1 at diagnosis (n = 91, 64.1%). History of smoking was present in 115 patients (79.8%). Ki-67 was analyzed in 38 patients (36.4%) and was ≥50% in 30 patients. 108 patients (75%) had metastatic disease at diagnosis, more frequently bone (n = 61, 42.4%) and liver (n = 50, 34.7%) metastasis. Initial treatment had palliative intent in 118 patients (81.9%), and 41 (28.5%) underwent only symptomatic treatment. The most commonly used chemotherapy regimen was the doublet of platinum and etoposide (n = 98, 95.1%). The overall response rate (ORR) was 64%. Median overall survival (OS) was 5.5 months (95% confidence interval (CI) 2.9-7.9). Within patients submitted to radical treatment (n = 26, 18.1%), there was relapse in 15 (57.7%), with a median disease free survival of 10.5 months (95% CI: 9.4-11.7). Within patients submitted to palliative treatment there was progression in 43 (not evaluated in 28), with a median progression free survival of 6.3 months (95% CI: 5.9-6.7). The median OS of the patients without metastatic disease at diagnosis was significantly higher than those with metastatic disease (median 15.9 months, 95% CI: 12.3-19.4 versus 3.1 months (95% CI: 2.1 -4.1, p < 0.001).

      Conclusions:
      The results obtained in our sample are in agreement with the existing literature. The discovery of predictive and predictive biomarkers as well as new forms of treatment is urgently needed.
