P2.13-10 - Lymph Node Upstaging Evaluation After Robotic Resection for NSCLC in Brazil (Now Available) (ID 934)
10:15 - 18:15 | Author(s): Rui Haddad
- Abstract
Background
An adequate lymph node staging plays a key role in the management of Non-Small Cell Lung Cancer (NSCLC) having great value in determining the necessity for adjuvant therapy. Inasmuch as the development of surgical robotic devices and robotic lobectomy is prominent, it is important to study if the robotic approach is capable of yielding the same or better lymph node staging as open or video assisted technique(VATS).The prevalence of nodal upstaging has been used as an adequate evaluation of the completeness of lymphadenectomy. The aim of this study was to determine the prevalence of lymph node upstaging in patients treated for NSCLC using robotic approach during the initial adoption of this method in Brazil.
Method
It was a descriptive analysis with retrospective collection of data from patients submitted to treatment for NSCLC with curative intention using robotic technique in different centers in Brazil. All data regarding demographics in addition to clinical and pathological details about nodal staging were collected. Patients with incomplete records about staging were excluded.
Result
We included 172 patients operated on from January 2015 to March 2019 . The average age was 65.7 years, 87 were female and 85 male. The most frequent histologic types were adenocarcinoma with 131(75.7%) cases , carcinoid tumors with 22(12.7%) cases followed by 17(9.8%) squamous carcinomas , 2 (1.1%) large cell carcinomas and 1 (0.5%) adenosquamous carcinoma. One of the patients had 2 tumors with different histotypes (large cell carcinoma and adenocarcinoma). The most frequent stage was IA both in clinical (118,68.6%) and pathological (114, 66.2%) and the average tumor size was 20mm. There was upstaging in 34 (19.7%) cases and down staging in 30( 17.4 %) cases. Lobectomy was the most frequent type of resection with 140 cases. On average 11.9 lymph nodes were resected and 5.8 node categories were addressed. Nodal upstaging occurred in 17 cases (9.8%) of which 8(4.6%) were N1-2 upstaging 6(3.4%) N0-1 upstaging and 3(1.7%) N1-2 upstaging. The incidence of nodal upstaging found was comparable with others studies.
Conclusion
In our experience , the treatment for NSCLC using the robotic approach was able to perform an adequate lymphadenectomy with prevalence rate comparable to previous data in literature.
