PURPOSE: To determine the prognostic value of pre- treatment serum LDH levels and the LDH isoenzyme pattern for non-small cell lung cancer, and to determine the relationship between the response to chemotherapy and the changes in serum LDH levels following chemotherapy MATERIALS AND METHODS: Patients with pathologically confirmed non-small cell lung cancer were entered onto this study. Their serum LDH levels were assessed prior to chemotherapy, with the LDH isoenzyme being assessed in patients with high initial serum LDH levels. The serum LDH levels were re-assessed following 2 cycles of chemotherapy. The relationship between the response to chemotherapy, pre-treatment serum LDH levels and LDH isoenzyme pattern and the changes in serum LDH levels, following chemotherapy, were evaluated. RESULTS: 49 patients were entered onto this study. The pre-treatment serum LDH levels were normal in 26 patients, and elevated in 23. The LDH isoenzyme was evaluated in 15 patients, with LDH2 being elevated the most frequently. The response rate to chemotherapy was 42.9% in all 42 patients able to be evaluated, 45.8% in patients with normal serum LDH levels and 41.2% in patients with elevated serum LDH levels. This difference was not statistically significant (p=0.767). The median survival was 37 weeks in all patients able to be evaluated, 38 weeks in those with normal serum LDH levels and 31 weeks in those with elevated serum LDH levels. These differences were not statistically significant (p=0.202). The patients with normal serum LDH levels following chemotherapy were more responsive to chemotherapy than those with elevated serum LDH levels following chemotherapy (response rate 51.4% vs. 0%, p=0.027). CONCLUSION: The LDH2 are most commonly elevated in non small cell lung cancer patients. The pre-treatment serum LDH levels do not reflect the prognosis accurately. The serum LDH levels following chemotherapy are associated with the response to chemotherapy.

Locally advanced Non-small cell lung cancer (NSCLC) is a commonly encountered diagnosis. Historically the treatment of locally advanced NSCLC has involved radiation therapy. Clinical trials have shown a benefit to the addition of chemotherapy. In recent years studies have further defined the role of chemotherapy by provided data showing the benefit of concurrent chemotherapy and radiation therapy followed by consolidation with more chemotherapy. Technological advances in radiation therapy have made dose escalation feasible and the current treatment paradigm is now evolving further as dose escalation data becomes available.

Radiation therapy has played a key role, together with surgery and systemic chemotherapy, in treating in all stages of non-small cell lung cancer. We have witnessed remarkable improvements in radiation therapy techniques, with the innovations in hardware and software. Stereotactic ablative radiation therapy, which can deliver high radiation dose focused to small target volume, represents one of the state-of-the-art radiation therapy techniques. The technical development of radiation therapy and the role of stereotactic ablative radiation therapy in treating inoperable stage I non-small cell lung cancer are briefly reviewed.
