P1.07-011 - 'Peripheral Limited' Small Cell Lung Cancer (SCLC). Does Surgical Resection Have a Role in Primary Management? (ID 3138)
09:30 - 09:30 | Author(s): B.A. Jobe
- Abstract
Background:
Limited stage SCLC, even peripheral completely resectable disease, is considered by many thoracic oncologic specialists to be a systemic process with a limited role of surgery beyond diagnosis. We hypothesized that surgical resection may improve local control, and potentially enhance survival for the small subset of SCLC patients (pts) with peripheral, resectable disease.
Methods:
Retrospective review of outcomes of all pts (n=127) with “limited stage” SCLC treated at our Institution from 2004-2014. Local disease progression and distant recurrence among pts undergoing primary systemic therapy +/- radiation therapy (n=106, 83%) were compared to pts with peripheral SCLC (n=21, 17%) undergoing surgical resection as first line therapy + adjuvant therapy. Patient demographics, surgical mortality, disease-free and overall survival outcomes were compared between the non-surgical and surgical groups. Systemic therapy was Platinum agent based. Survival was estimated using Kaplan-Meier survival analysis. Groups were compared using a log-rank test.
Results:
Pts demographics were similar between non- surgical and surgically treated SCLC pts. Systemic therapy / radiation was utilized for 88 (83%) non-surgical pts. Systemic therapy alone was utilized for 18 (16.9%) pts, and 2 (1.8%) patients received radiotherapy alone. Local disease progression represented first site of treatment failure in 19 (17.9%), while distant metastases was first noted in 65 pts (61.3%). Of the 65 distant metastasis first site of progression, 27 (41.5%) were cerebral. First site of progression was unable to be verified 16 (26.2%) medically treated pts. Among the 21 pts having “surgical resection” of peripheral, limited SCLC, there was no perioperative (30 day) mortality. Local recurrence was noted first in 7 (33.3%) of surgical pts. Distant metastases was discovered first in 3 (14.3%), and cerebral metastasis was found in 2 of these 3 pts. Nine (42.9%) surgical pts were recurrence free (mean 43 months), while only 7 (5.7%) medically treated pts were free of recurrence (mean 31 months). The 5 year survival among medially treated pts was 8% compared to 21% among patients undergoing surgical resection of peripheral SCLC (p= 0.008). (See figure 1. below) Figure 1
Conclusion:
Survival for all SCLC patients is affected by the common presence of systemic disease, despite an apparently limited, peripheral disease presentation. Surgical resection as “First line” therapy combined with adjuvant systemic + radiation therapy for peripheral, limited small cell lung cancer may be beneficial. Cerebral metastases are important sites of first distant recurrence for all limited stage SCLC.

P2.03-007 - Pneumonectomy for Non Small Cell Lung Carcinoma: Pre-Operative Comorbidities and Post-Operative Morbidity Affect Long Term Survival (ID 3160)
09:30 - 09:30 | Author(s): B.A. Jobe
- Abstract
Background:
Pneumonectomy for NSCLC is commonly associated with significant morbidity and mortality. Patients with pre-existing medical comorbidities experience an increased frequency of post-operative complications. This is of increased importance in this patient population, compared to patients undergoing lesser anatomic resections, as it is associated with a decrease in overall survival.
Methods:
A retrospective review of all patients undergoing pneumonectomy for non small cell lung cancer from 2004 to 2014 was undertaken. IRB approval was obtained. Demographics and pre-existing medical comorbidities, including the utilization of neoadjuvant therapy, were evaluated. Major morbidities occurring in the post-operative period were evaluated. Stage specific survival was evaluated and compared to published survival data following anatomic lobectomy.
Results:
From 2004 to 2014, 84 pneumonectomies were performed for resectable non small cell lung carcinoma. Complete STS data and staging information was available for 81 patients. Demographics and pre-existing medical comorbidities are reported in Table 1. Post-operative major morbidities are reported in Table 2. Mean stage specific survival was 32, 28 and 26 months for Stage I, II and III respectively. Figure 1 Figure 2
Conclusion:
Overall survival is decreased in patients undergoing pneumonectomy for NSCLC compared with patients undergoing lesser anatomic resections. Pre-existing medical conditions may contribute to the increased frequency of post-operative morbidity, resulting in decreased overall survival in these patients. Further evaluation of the severity of pre-existent medical comorbidities and the impact on post-operative morbidity on long term survival following pneumonectomy for non small cell lung carcinoma is warranted.
