Trimodality therapy for superior sulcus non-small cell lung cancer: Southwest Oncology Group-Intergroup Trial S0220.

ABSTRACT:

Background

Although preoperative chemotherapy (cisplatin-etoposide) and radiotherapy, followed by surgical resection, is considered a standard of care for superior sulcus cancers, treatment is rigorous and relapse limits long-term survival. The Southwest Oncology Group-Intergroup Trial S0220 was designed to incorporate an active systemic agent, docetaxel, as consolidation therapy.

Methods

Patients with histologically proven and radiologically defined T3 to 4, N0 to 1, M0 superior sulcus non-small cell lung cancer underwent induction therapy with cisplatin-etoposide, concurrently with thoracic radiotherapy at 45 Gy. Nonprogressing patients underwent surgical resection within 7 weeks. Consolidation consisted of docetaxel every 3 weeks for 3 doses. The accrual goal was 45 eligible patients. The primary objective was feasibility.

Results

Of 46 patients registered, 44 were eligible and assessable; 38 (86%) completed induction, 29 (66%) underwent surgical resection, and 20 (45% of eligible, 69% surgical, and 91% of those initiating consolidation therapy) completed consolidation docetaxel; 28 of 29 (97%) underwent a complete (R0) resection; 2 (7%) died of adult respiratory distress syndrome. In resected patients, 21 of 29 (72%) had a pathologic complete or nearly complete response. The known site of first recurrence was local in 2, local-systemic in 1, and systemic in 10, with 7 in the brain only. The 3-year progression-free survival was 56%, and 3-year overall survival was 61%.

Conclusions

Although trimodality therapy provides excellent R0 and local control, only 66% of patients underwent surgical resection and only 45% completed the treatment regimen. Even in this subset, distant recurrence continues to be a major problem, particularly brain-only relapse. Future strategies to improve treatment outcomes in this patient population must increase the effectiveness of systemic therapy and reduce the incidence of brain-only metastases.

Project description:PurposeFour US National Clinical Trials Network components (Southwest Oncology Group, Cancer and Leukemia Group B/Alliance, Eastern Cooperative Oncology Group, and the AIDS Malignancy Consortium) conducted a phase II Intergroup clinical trial that used early interim fluorodeoxyglucose positron emission tomography (FDG-PET) imaging to determine the utility of response-adapted therapy for stage III to IV classic Hodgkin lymphoma.Patients and methodsThe Southwest Oncology Group S0816 (Fludeoxyglucose F 18-PET/CT Imaging and Combination Chemotherapy With or Without Additional Chemotherapy and G-CSF in Treating Patients With Stage III or Stage IV Hodgkin Lymphoma) trial enrolled 358 HIV-negative patients between July 1, 2009, and December 2, 2012. A PET scan was performed after two initial cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and was labeled PET2. PET2-negative patients (Deauville score 1 to 3) received an additional four cycles of ABVD, whereas PET2-positive patients (Deauville score 4 to 5) were switched to escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (eBEACOPP) for six cycles. Among 336 eligible and evaluable patients, the median age was 32 years (range, 18 to 60 years), with 52% stage III, 48% stage IV, 49% International Prognostic Score 0 to 2, and 51% score 3 to 7.ResultsThree hundred thirty-six of the enrolled patients were evaluable. Central review of the interim PET2 scan was performed in 331 evaluable patients, with 271 (82%) PET2-negative and 60 (18%) PET2-positive. Of 60 eligible PET2-positive patients, 49 switched to eBEACOPP as planned and 11 declined. With a median follow-up of 39.7 months, the Kaplan-Meier estimate for 2-year overall survival was 98% (95% CI, 95% to 99%), and the 2-year estimate for progression-free survival (PFS) was 79% (95% CI, 74% to 83%). The 2-year estimate for PFS in the subset of patients who were PET2-positive after two cycles of ABVD was 64% (95% CI, 50% to 75%). Both nonhematologic and hematologic toxicities were greater in the eBEACOPP arm than in the continued ABVD arm.ConclusionResponse-adapted therapy based on interim PET imaging after two cycles of ABVD seems promising with a 2-year PFS of 64% for PET2-positive patients, which is much higher than the expected 2-year PFS of 15% to 30%.
