Pignon et al (NEJM 1992) evaluated 13 randomized trials:

Thoracic Radiotherapy in LS-SCLC: an absolute benefit in overallsurvival of 5.4% at 3 years and a 14% reduction in mortality.

Warde and Payne (JCO 1992) evaluated 11 randomized trials:

The addition or RT to Chemotherapy showed an overall survivalbenefit of 5.4% at 2 years.

Some conclusions for the daily practice

QT: Platinum-etoposide

Concomitant QT+RT better than sequential

Early RT: as soon as posible…better outcomesin the first 30 days

RT: dose, HF-RT??? Early RT > Late RT with HF-RT

PCI improves survival

Extensive Stage SCLCTHE LAST 10 or 20 YEARS SUMMARY…

SCLC is highly sensitive to chemotherapy and radiotherapy

Despite the high chemosensitivity, median survival remainspoor for patients with ES ranges only from 7 to 11 months

Platinum-etoposide is the standard of care in first linetreatment since the 1980s• ORR: 50-60%

• Median Survival: 9-12 months

• Topotecan is the standard of care in second-line therapy

SOME AND RELEVANT QUESTIONS in the 1st line setting…

What is the best 1st line regimen?

Is there a role for dose-intensive chemotherapy?

Is there a role for maintenance chemotherapy?

Is there a role for antiangiogenic agents?

Is there a role for inmunotherapy treatments?

Is there a role for preventive brain irradiation ?

Is there a role for thoracic radiotherapy?

dose intensity, peak dose, or total dose of chemotherapy, so intensification strategy should be

probably abandoned

Have we made any progress?

I have my own personal opinion and it’s not too positive …

Why son many failures?

Reasons for the failure

Wrong design of clinical trials

Wrong drugs

Wrong targets

Wrong doses

Unknown molecular mechanisms of the disease

…….

Some ideas for the future…

Define SCLC biology to identify new actionablemolecular targets

Increase the diversity of agents

To abandon empiricism in favor of molecularlybased clinical trial design.

IO agents may be a good option for the future…

Novel molecular targets in SCLCSome hope for the future…
