Radiotherapy may be used in patients who are medically unsuitable for surgery. The role of induction chemotherapy in these early stages is still under investigation.Locally or regionally advanced tumors (stage III) are usually too extensive curative surgery, but are still confined to the chest. The standard treatment is chemotherapy plus radiotherapy. Downstaging the tumor with chemotherapy (with or without radiotherapy) may allow surgery in certain cases.Advanced tumors (stage IV) are treated with chemotherapy. Palliative radiotherapy may be used to relieve symptoms.1. PDQ Treatment Guidelines.

Adjuvant chemotherapy or radiotherapy following surgery, and neoadjuvant chemotherapy, are currently under investigation.11. PDQ Treatment Guidelines.

The recurrence rate was three times higher in the patients undergoing limited resection, and the death rate was increased by 30%.1Similarly, a retrospective non-randomized study in 173 patients with stage I NSCLC found that the percentage of patients experiencing a local or regional recurrence within 5 years was higher in patients undergoing anatomic segmentectomy than lobectomy.21.

The square represents the mean hazard ratio for each trial, and the outer and inner bars show the 95% and 99% confidence intervals. The size of the square represents the size of the trial.The center of the diamond represents the overall hazard ratio from all the trials combined, and its ends represent the 95% confidence interval.The majority of the trials reported a hazard ratio of <1 (to the left of the solid vertical line), indicating superior survival in the groups treated with radiotherapy plus chemotherapy.The overall hazard ratio was 0.87, indicating a 13% lower risk of death for the patients receiving combination treatment (p=0.005).Combined chemotherapy and radiotherapy is an appropriate treatment for patients with good performance status and weight loss of <5%. However, radiotherapy alone may be more appropriate for patients with stage III NSCLC with poor performance status or weight loss of 5% or more during the preceding 3-6 months.21.

Results of two large phase III trials reported at ASCO1,2 show a broad range of response rates (15-27%) with these new combinations, but this does not translate into a significant impact on median survival (range months).1.

The strain is relieved by DNA topoisomerases, which make a transient break in the DNA backbone to permit unwinding. Topoisomerase inhibitors increase the frequency of these breaks, which eventually triggers programmed cell death.1DNA synthesis requires a constant supply of nucleotides. The supply of the thymidylate nucleotide can be blocked by inhibition of thymidylate synthase. This enzyme is the target of antifolate drugs such as ZD9331,2 multitargeted antifolate (MTA, LY231514),3 and the benzoquinolone 1843U89.41. Fortune JM, et al. Biochemistry 1999; 38:2.

Thus, survival is usually not affected by small changes in the amount of locoregional tumor involvement, as it is for NSCLC. Thus, the detailed TNM staging previously described, although relevant is not commonly employed for staging SCLC.Instead, a simple 2-stage system, limited or extensive stage SCLC, is used.In limited-stage disease the tumor is confined to the hemithorax of origin, the mediastinum and the supraclavicular nodes, which can be encompassed within a ‘tolerable radiation’ therapy port.1The extensive-stage of SCLC encompasses any tumor too widespread to be included within the definition of limited-stage and any patients with distant metastasis.11.

25SCLC: sopravvivenza % Pazienti Mal. limitata Mal. Estesa Based on US figures from , 5-year survival in patients with SCLC is 6.2%.1Disease stage is one of the most important prognostic factors in SCLC. In a randomised study, in which two combination chemotherapy regimens were compared, prognostic factors were analysed in 286 patients. Disease stage was the primary pretreatment predictor of 3-year survival; 19.2% of patients with limited-stage disease survived for 3 years, compared with 3.5% with extensive-stage disease.2 The median survival duration for patients treated with combination chemotherapy is 10 to 14 months for patients with limited-stage and 7 to 11 months for those with extensive-stage, the most commonly diagnosed SCLC.3References1.

A number of combination chemotherapy protocols have demonstrated activity in patients with limited-stage SCLC, with overall response rates of 80-95%.These include cisplatin/etoposide (PE), cisplatin/etoposide/vincristine (PEV), cyclophosphamide/doxorubicin/vincristine (CAV), cyclophosphamide/ doxorubicin/etoposide (CAE) and cyclophosphamide/doxorubicin/ vincristine/etoposide (CAVE).In patients with limited stage disease median survivals of 12.4 and 15.1 months have been reported following treatment with CAV and CAVE, respectively. 1,2 In addition, the complete response rate was 16% and 48%, with CAV and CAVE, respectively.1,2There is some evidence that alternating chemotherapy regimens (PE/CAV) in patients with limited disease may be beneficial.1,3There is no compelling evidence that maintenance chemotherapy prolongs survival for patients with SCLC. In fact it may produce more toxicity and thus negatively impact on the quality of life.41. Fukuoda M, et al. J Natl Cancer Inst 1991; 83:2. Goodman GE, et al. J Clin Oncol 1990; 8:3.

In this study, administration of thoracic RT led to a 14% reduction in mortality rate (p=0.001), which corresponded to a 5% increase in the 3-year survival rate.1A similar result was also demonstrated in another meta-analysis of 11 randomized trials.2 Most of the benefit occurred in patients <55 years.Thus, in limited stage SCLC, combination chemotherapy plus chest RT is considered a standard treatment for patients with limited-disease SCLC.31.

This study showed that patients who are in complete remission have a 60% risk of developing CNS metastases within 2 to 3 years of treatment, and administration of PCI reduces the risk by more than 50%.1Several randomized studies have failed to demonstrate a benefit for PCI in improving overall survival, and side effects, such as neuropsychiatric abnormalities have been a concern.However, neurological abnormalities have been shown to exist in 30-40% of SCLC patients prior to PCI and a recent meta-analysis demonstrated an absolute 5.4% increase in 3-year survival rate in favor of PCI.2It is now generally accepted that PCI should be administered to patients with limited-stage disease in complete remission after induction chemotherapy.21.

Palliation of symptoms with short-term local control and external-beam radiation therapy can be carried out.1 In addition, in patients with intrinsic endobronchial obstructing lesions or extrinsic compression, endobronchial laser therapy and/or brachytherapy may be beneficial.1 Endobronchial stents can be inserted in patients with malignant airway obstruction.1Late relapsing patients with a long-treatment-free interval frequently respond to combination chemotherapy, which may be identical to their first-line treatment (response rates of up to 50-60%).1Both refractory and early relapsing patients with a short treatment-free interval, only have a small chance of responding to any drug.1,2 These patients are candidates for Phase II studies with new agents.1,21.

As single agents in extensive- stage SCLC patients, the taxoid, docetaxel gives comparable survival outcomes to that of standard single agent treatment.1,2 Docetaxel is currently in Phase II combination trials. The response rates of paclitaxel and irinotecan as single agents in Phase II trials were also similar to those of established drugs, and they are also currently being examined in combination chemotherapy trials.3,4ZD0473 is a platinum drug designed with the capacity to overcome acquired or de novo resistance, particularly to overcome thiol-mediated resistance.
