Inclusion Criteria:

- Histologically or cytologically confirmed primary non-small cell lung cancer (NSCLC)*
meeting the following criteria:

- Squamous cell or mixed squamous-nonsquamous histology with predominant squamous
component (≥ 50% squamous) with a primary, unresected endobronchial lesion

- No small cell component

- Centrally located primary tumor, defined by the following:

- Primary tumor of any T stage within or touching the zone of the proximal
bronchial tree

- Zone is defined as a 3-dimensional volume with a perimeter of 2 cm in
each direction around the proximal bronchial tree (carina, right and
left main bronchi, right and left upper lobe bronchi, intermedius
bronchus, right middle lobe bronchus, lingular bronchus, right and
left lower lobe bronchi)

- Any disease within this volume must not invade blood vessels
determined by a contrast-enhanced CT scan evaluation of the entire
thorax with thin slices (≤ 5 mm) through the area of central tumor
bulk (i.e., no evidence of vessel invasion radiological evaluation)

candidates for combined modality therapy with curative intent (i.e., radical
chemoradiotherapy)

- Hemoptysis estimated as between 2.5 mL and 10 mL (largest volume of single
episode of hemoptysis) in the past 2 months

- Measurable disease, defined as ≥ 1 unidimensionally measurable lesion ≥ 20 mm by
conventional techniques or ≥ 10 mm by spiral CT scan

- No known brain metastases by contrast-enhanced CT scan or gadolinium-enhanced MRI of
the brain

- No clinical or radiologic evidence of an existing or impending spinal cord
compression

- ECOG performance status (PS) 0-1 OR Karnofsky PS 70-100%

- Life expectancy > 6 months

- WBC ≥ 3,000/mm³

- Absolute neutrophil count ≥ 1,500/mm³

- Platelet count ≥ 100,000/mm³

- Bilirubin normal

- AST and ALT ≤ 2.5 times upper limit of normal (ULN)

- Creatinine normal OR creatinine clearance ≥ 50 mL/min

- INR < 1.5

- aPTT ≤ 1.5 times ULN

- Unstable angina

- Myocardial infarction or stroke (cerebrovascular accident or transient ischemic
attack) within the past 6 months

- No other active malignancy

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception during and for ≥ 6 months after
completion of study treatment

- No history of bleeding diathesis or coagulopathy associated with elevated risk of
bleeding

- No uncontrolled hypertension (i.e., resting blood pressure consistently higher than
systolic > 150 mm Hg and/or diastolic > 100 mm Hg with or without antihypertensive
medication), history of labile hypertension, or history of poor compliance with
antihypertensive medication

- No clinically significant proteinuria (24-hour urine protein < 1,000 mg)

- No serious or nonhealing wound, ulcer, or bone fracture

- No abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within
the past 28 days

- No significant traumatic injury within the past 28 days

- No history of known allergy or reaction attributed to compounds of similar chemical
or biological composition to bevacizumab, such as Chinese hamster ovary cell proteins
or other recombinant human or humanized antibodies, Cremophor EL®, or other agents
used in study treatment

- No pre-existing peripheral neuropathy > grade 1

- No prior thoracic radiotherapy

- At least 12 months since prior chemotherapy

- No prior chemotherapy for advanced disease

- No prior therapy with angiogenesis, vascular endothelial growth factor (VEGF), or
VEGF-receptor inhibitors

- Cyclooxygenase-2 inhibitors as a noncancer therapy allowed

- At least 28 days since prior and no concurrent major surgery or open biopsy

- At least 12 months since prior anticancer therapy for any other malignancy except
basal cell carcinoma of the skin, localized prostate cancer, or in situ carcinoma of
the cervix

- At least 10 days since prior therapeutic anticoagulants or therapeutic thrombolytic
agents

- No concurrent aspirin (> 325 mg/day) or antiplatelet agents, including dipyridamole,
ticlopidine, clopidogrel bisulfate, or cilostazol

- Other concurrent nonsteroidal anti-inflammatory drugs allowed

- No other concurrent investigational agents

- No concurrent combination antiretroviral therapy for HIV-positive patients
