Early Stage Operable NSCLC
Primary surgery vs. primary RT
- Medical Research Council/Hammersmith Hospital (1954-1958) -- RT vs Surgery
- Randomized. 58 patients, no clinical or radiologic evidence of mediastinal involvement. Biopsy proven carcinoma. Arm 1) RT - using 8 MeV linac, 45 Gy in 4 weeks daily. Target + 2cm + hilar/mediastinal areas; vs. Arm 2) Surgery - pneumonectomy or lobectomy + hilar/mediastinal LND. However 13/30 weren't operable/refused. Histology squamous 64%, adenocarcinoma 3%, small cell/anaplastic 33%
- 1963 PMID not available, doi:10.1016/S0140-6736(63)91444-2 --"THE TREATMENT OF CARCINOMA OF THE BRONCHUS A Clinical Trial to Compare Surgery and Supervoltage Radiotherapy" (Morrison R, Lancet. 1963. Mar 30; 281(7283):683-684)
- Outcome: 1-year OS RT 64% vs. Surgery 43%; 2-year OS 14% vs. 27%; 4-year 7% vs. 23% (NS). By histology: squamous 6% vs. 30% (SS); small cell 10% both (NS)

- Locoregional recurrence: limited resection 17% vs. lobectomy 6% (SS, 3x higher). Death rate: 39% vs. 30% (NS)
- Tumor volume: lobectomy better, regardless of tumor size (<3 cm3, 3-8 cm3, 8-27 cm3)

- Toxicity: If pneumonectomy (35% in both groups), worse mortality 14% vs. 6%
- Conclusion: Preop chemo-RT increases mediastinal downstaging, but doesn't improve survival. After induction, pneumonectomy should be avoided
Prophylactic Cranial Irradiation (PCI)

- Outcome: MS induction 12 months vs. no induction 14 months (NS); 2-year OS 29% vs. 31% (NS)
- Toxicity: Induction chemo neutropenia (20% Grade 3-4), no difference between concurrent CRT arms
- Conclusion: Addition of induction chemo added toxicity without survival benefit.
- Comment: Low survival compared to other trials, possibly due to lower chemo dose due to using carboplatin and not cisplatin.
Chemo-RT +/- chemotherapy consolidation

- Conclusion: Consolidation with docetaxel increased toxicity with no impact on survival
- SWOG 0023 (2001-2005) -- Chemo-RT and adjuvant docetaxel +/- adjuvant gefitinib
- Randomized. Closed early after worse survival with gefitinib. 243/672 patients, Stage III NSCLC. Concurrent cisplatin 50 mg/m2 + etoposide 50 mg/m2 + RT 61 Gy, then docetaxel 75 mg/m2 x3 cycles. If no progression, randomized Arm 1) gefitinib 250 mg/d vs. Arm 2) placebo until progression, toxicity or 5 years

- Outcome: median OS gefitinib 1.9 years vs. placebo 2.9 years (SS)
- Toxicity: death rate gefitinib 2% vs. placebo 0%
- Conclusion: Gefitinib didn't improve survival; decreased survival result of tumor progression and not gefitinib toxicity
- Institute for Cancer Research, Oslo (1995-1998) -- observation vs metoclopramide

- Randomized. Trial stopped prematurely due to financial difficulties. 30 patients enrolled, 16 analyzable, NSCLC stage IIIA/IIIB. RT 60/33. Arm 1) observation vs Arm 2) concurrent metoclopramide 2mg/kg TIW. Analysis of CT density
- Outcome: Lung density increased with dose (SS). Patients on metoclopramide less increase in tissue density (SS)
- Conclusion: Metoclopramide and large radiation dose seemed to protect against fibrosis development
- Japan WJTOG 3405
- Randomized. 172 chemo-naive patients, age <=75, Stage IIIB/IV NSCLC or postop recurrence, with EGRF mutation (exon 19 deletion or L858R point mutation). Arm 1) Gefitinib 250 mg QD vs Arm 2) cisplatin 80 mg/m2 and docetaxel 60 mg/m2 Q3W x 3-6 cycles. Primary endpoint PFS
- 2009 PMID 20022809 -- "Gefitinib versus cisplatin plus docetaxel in patients with non-small-cell lung cancer harbouring mutations of the epidermal growth factor receptor (WJTOG3405): an open label, randomised phase 3 trial." (Mitsudomi T, Lancet Oncol. 2009 Dec 18. [Epub ahead of print])
- Outcome: Median PFG gefitinib 9 months vs. cisplatin/docetaxel 6 months (SS)
- Toxicity: Myelosuppression, alopecia, and fatigue more frequent in cisplatin/docetaxel group, but skin toxicity, liver dysfunction, and diarrhoea more frequent in the gefitinib group. Two patients (2%) developed interstitial lung disease
- Conclusion: Patients with EGFR mutations have longer PFS on gefitinib than on cisplatin/docetaxel
Quality of Life
- RTOG 9801 -- Induction -> concurrent chemo-AHFX RT +/- amifostine
- Randomized. 243 patients with unresectable NSCLC (II-IIIB). Induction paclitaxel 225 mg/m2 and carboplatin AUC6 x2 cycles, then concurrent chemo-RT. RT 69.6/58 @ 1.2 GY BID with concurrent paclitaxel 50 mg/m2 and carboplatin AUC2. During chemo-RT Arm 1) placebo vs. Arm 2) amifostine 500 mg IV (72% received it per protocol)
- 2005 PMID 15800308 -- "Randomized trial of amifostine in locally advanced non-small-cell lung cancer patients receiving chemotherapy and hyperfractionated radiation: radiation therapy oncology group trial 98-01." (Movsas B, J Clin Oncol. 2005 Apr 1;23(10):2145-54.)
- Outcome: Grade 3+ acute esophagitis AM 30% vs no AM 34% (NS); patient reported dysphagia significantly better with AM (p=0.02). But, AM higher acute nausea (SS), vomiting (SS), CV toxicity (SS), and infection/neutropenia (SS). No difference in QOL
- Survival: AM 17.3 months vs. no AM 17.9 months (NS)
- Conclusion: Amifostine did not significantly reduce grade 3+ esophagitis, though patient self-assessment suggested an advantage
