P3.01-079 - Evaluating the Roles of Neoadjuvant and Adjuvant Chemotherapy for Treating Patients with Stage IIIa (N2) Lung Cancer (ID 10124)
09:30 - 09:30 | Author(s): Mong-Wei Lin
- Abstract
Background:
The survival benefit of systemic chemotherapy has been demonstrated for treating patients with stage IIIa (N2+) lung cancer. The NCCN guideline recommends induction chemotherapy with or without irradiation followed by surgery for those patients if no disease progression was noted after induction therapy. However, there are also studies revealed the survival benefit of adjuvant chemotherapy for patients with N2+ IIIa disease. The current study compared the survival results of neoadjuvant (before surgery, BS) and adjuvant (after surgery, AS) chemotherapy plus surgical resection for the patients with non-small cell lung cancer with N2+ stage IIIa disease.
Method:
There were 217 patients with Stage IIIa N2+ who ercieved surgery resection in the recent decade in our hospital, with a mean follow-up duration of 44 months. The overall survival time was evaluated and compared between these three groups of patients
Result:
Figure 1There were 62, 44 and 111 patients without chemotherapy(C/T) (Nil) or C/T given as neoadjuvant (BS) and adjuvant (AS) setting respectively. There were more patients with advanced age in the Nil and AS groups and more patients with AS group have received sublobal resection (p<0.01 respectively) as compared to the patients of BS group. The mean survival duration after surgery for the patients of AS and BS groups was 57.6 and 50.4 months respectively which was signinficantly longer than those patients of Nil group (MST: 26.4 months : p<0.001 respectively). Multivariate analysis revealed the addition of chemotherapy as a single prognostic factor of the patients. However, there was no significant difference of survival duration between the patients of AS and BS groups.
Conclusion:
Chemotherapy given both as adjuvant or neoadjuvant setting can provide a survival benefit for the patients with stage IIIa N2+ non-small cell lung cancer after surgery. No statistical difference was observed about the survival duration for these two groups of patients.

P3.17-002 - Comparison of Single- and Multi-Incision Minimally Invasive Esophagectomy for Treating Esophageal Cancer: A Propensity-Matched Study (ID 8366)
09:30 - 09:30 | Presenting Author(s): Mong-Wei Lin
- Abstract
Background:
To compare the perioperative outcome of minimally invasive (MIE) esophagectomy performed with a single- or a multi-incision in treating esophageal cancer.
Method:
Patients with esophageal cancer who underwent MIE from 2006 to 2016 were evaluated. A 3–4-cm incision was created in both the thoracoscopic and the laparoscopic phases during the single-incision MIE procedures. A propensity-matched comparison was made between the two groups of patients.
Result:
We analyzed a total of 48 pairs of patients with propensity-matched from the cohort of 360 patients undergoing MIE during 2006–2015. There is no statistical difference in terms of postoperative ICU and hospital stay, number of dissected lymph nodes and presence of major surgical complications (anastomotic leakage and pulmonary complications) between the two groups of patients. The pain score one week after surgery was significantly lower in the single-incision group (p < 0.05). There was no surgical mortality in the single-incision MIE group.
Conclusion:
Minimally invasive esophagectomy performed with a single-incision approach is feasible for treating patients with esophageal cancer, with a comparable perioperative outcome with that of multi-incision approaches. The postoperative pain one week after surgery was significantly reduced in patients undergoing single-incision MIE.
