      Background:
      Small cell lung cancer (SCLC) as the most aggressive tumor deserves a special attention. The aim of this research was to define the place of surgery of patients with SCLC in order to improve the results of treatment.

      Methods:
      Clinical material for research consists of 46 patients in stage IA-IIIA with SCLC, which were radically operated in Ugra (region Russia) between 1999 and 2013. Among patients predominate males 38 (82,6%), versus females – eight (17,4%).

      Results:
      All patients underwent radical operations R0. All resection types were included (pneumonectomy, bilobectomy, and lobectomy). By 32 patients (69,6%) systematic nodal dissection (SND) was carried out, by 5 (10,9%) - mediastinal lymph node sampling (MLS) and by 9 patients mediastinal node dissection was not carried out. By SCLC combination treatment was used more often – 32 (69,6%). By that only in 8 cases additional adjuvant of thoracic radiotherapy was used. In 14 cases only surgical resection was used (30,4%). 5-year overall survival (OS) rate was 47,1%. Median survival rate was 58 months. Five-year OS rate by surgery combined with adjuvant chemotherapy was 52,1%, as compared to only surgical treatment – 35,6%. At I stage satisfactory results were achieved: 5-year OS rate was 69% (р<0,05), – that corresponds with results of treatment of patients with non-small cell lung cancer with similar stage of process. Median survival rate was not achieved. At II stage 5-year OS rate was 31%. Median survival rate was 46 months. At III stage unsatisfactory results were obtained. 5-year OS rate was 21%. Median survival rate was only 11 months.

      Conclusion:
      SCLC at I and II stages is the indication to radical treatment, mandatory including surgical resection with SND and adjuvant chemotherapy. The main method of treatment at III stage is chemotherapy or chemoradiotherapy.

      P3.04-012 - Bronchial Sutures in Anatomic Pulmonary Resections: The Clinical Experience of 865 Cases (ID 3869)

      Background:
      Although the incidence of bronchopleural fistula (BPF) has decreased in past time, it remains a serious complication following pulmonary resection.

      Methods:
      Between 1999 and 2011, 865 patients with lung cancer underwent radical surgery. 732 (84,6%) males and 133 (15,4%) females were ranging between 22 and 79 years (average 55,2±8,1). We retrospectively reviewed the data for morbidity, mortality and complications, especially with regard to the type of bronchial suture.

      Results:

      Rate BPF from the dependence of the type of bronchial suture
      Type of bronchial suture cases BPF %
      Stapled closure 210 14 6,7%
      Stapled closure with additinal hand suture 514 24 4.7%
      Hand closure 141 1 0,7%
      Total 865 39 4,5%
      All patients underwent radical operations: 286 (33,1%) pneumonectomies, 501 (57,9%) lobectomies and 78 (9,0%) bilobectomies. In postoperative period 39 patients (4,5%) had complication – bronchopleural fistula. After pneumonectomy BPF took place in 33 (11,5%) cases, not differing significantly from the volume of lymph node dissection. After lobectomy BPF occurred statistically significant rare – in 6 (1,0%) cases. It should be noted, that the volume of lymph node dissection not significantly affect the frequency BPF. The most frequently BPF occured after pneumonectomies – 33 (26 on the right, 7 left). After lobectomies BPF occurred in less cases – 6 (2 on the right, 4 left). By using hand closure BPF occurred in 1 out of 141 (0,7%) cases. By using stapled closure – in 14 of 210 (6,7%). By using stapled closure with additional hand suture – 24 of 514 (4,7%).

      Conclusion:
      Thus the safest method of bronchus closure is hand suture. The stapled closure statistically significant increase the amount of BPF (p<0,05).
