Before initiating treatment of a patient with small cell lung cancer (SCLC), an experienced lungcancer pathologist should review the pathologic material.
The current classification of subtypes of SCLC includes the following:
Small cell carcinoma.
Combined small cell carcinoma (i.e., SCLC combined with neoplastic squamous and/or glandular components).
SCLC arising from neuroendocrine cells forms one extreme of the spectrum of neuroendocrine carcinomas...
Standard treatment options for stage 0 NSCLC include the following:
Endobronchial therapies, including photodynamic therapy, electrocautery, cryotherapy, and Nd-YAG laser therapy.
Segmentectomy or wedge resection are used to preserve maximum normal pulmonary tissue since patients with stage 0 NSCLC are at a high risk for second lung cancers. Because these tumors are by definition noninvasive and incapable of metastasizing, they should be curable with surgical resection; however, such lesions, when identified, are often centrally located and may require a lobectomy.
Patients with central lesions may be candidates for curative endobronchial therapy. Endobronchial therapies that preserve lung function include photodynamic therapy, electrocautery, cryotherapy, and Nd-YAG laser therapy.[3,4,5,6]
Evidence (endobronchial therapies):
Small case series have reported high complete response rates and long-term survival in selected patients.[7,8][Level of evidence: 3iiiDiii]
Efficacy of these treatment modalities in the management of patients with early NSCLC remains to be proven in definitive randomized controlled trials.
There is a high incidence of second primary cancers developing.[1,2]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage 0 non-small cell lung cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
