For patients diagnosed with extensive-stage small-cell lung cancer (SCLC), the standard-of-care remains the chemotherapy combination of VePesid® (etoposide) and Platinol® (cisplatin). A recent study indicates that Camptosar® (irinotecan) plus Platinol does not improve survival in SCLC compared with VePesid/Platinol. These findings were presented at the 2008 annual meeting of the American Society of Clinical Oncology.

Small cell lung cancer (SCLC) accounts for approximately 25% of all cases of lung cancer in the United States. SCLC refers to the type of cell within the lung from which the cancer originated. It is considered a very aggressive form of lung cancer.

Extensive-stage SCLC refers to cancer that has spread from the lung to different sites in the body. Approximately two-thirds of patients diagnosed with SCLC have extensive-stage SCLC; a standard chemotherapy regimen for these patients is VePesid plus Paraplatin. However, due to suboptimal long-term outcomes for patients with SCLC, researchers continue to evaluate alternative chemotherapy combinations to standard therapy.

In 2002 a trial conducted by Japanese researchers reported that Camptosar/Platinol produced a significant improvement in survival over the standard VePesid/Platinol for extensive-stage SCLC. In light of these results, researchers with the Southwest Oncology Group (SWOG) conducted a trial to validate these findings among patients in North America.

The SWOG trial included 671 patients with extensive SCLC. Participants were divided into two groups; one group received Camptosar in addition to Platinol, while the other group received VePesid in addition to Platinol.

  • Median progression-free survival was similar between both groups: approximately six months for patients treated with Camptosar compared with approximately five months for those treated with VePesid.
  • Median overall survival was also not significantly different between the two groups: approximately ten months for the Camptosar group and approximately nine months for the VePesid group.

The researchers concluded that in North America, VePesid/Platinol remains the standard of care for patients diagnosed with extensive-stage SCLC. Patients undergoing treatment for SCLC may wish to discuss with their physician the risks and benefits of treatment with a combination of VePesid and Platinol.
