34. Positron emission tomography in pulmonary masses where tissue diagnosis is unhelpful or not possible

Author

Pitman, Alex G., Hicks, Rodney J., Kalff, Victor, Binns, David S., Ware, Robert E., McKenzie, Allan F., Ball, David L., and MacManus, Michael P.

Abstract

An investigation is conducted into the usefulness of positron emission topography (PET) in the diagnosis of lung masses, where tissue diagnosis is not available or useful. It is seen that PET could be used to avoid pen biopsy and contributed to improvements in the management of patients.

38. Symptom duration and delay in referral for palliative radiotherapy in cancer patients: a pilot study

Abstract

Referral for palliative radiotherapy for symptoms of cancer may be greatly delayed in Australia, subjecting patients to unnecessary pain. Researchers evaluated 158 cancer patients referred for radiation therapy to treat pain, spinal cord compression, and other complications. Radiotherapy referral was delayed an average of four weeks after symptoms began, and 24% of patients were delayed an average of 12 weeks. Eighteen percent of cases of delay resulted from initial use of other, often ineffective, treatment.

43. Respiratory-gated (4D) FDG-PET detects tumour and normal lung response after stereotactic radiotherapy for pulmonary metastases

Author

Abstract

Background. Response assessment after stereotactic ablative body radiotherapy (SABR) in lung can be confounded by radiation-induced inflammation, fibrosis and subsequent alteration of tumour motion. The purpose of this prospective pilot study was to evaluate the utility of four-dimensional (4D) FDG-PET/CT for post-SABR tumour and normal lung response assessment in pulmonary oligometastases.Material and methods. Patients enrolled from February 2010 to December 2011 in this prospective ethics approved study had 1–2 pulmonary metastases on staging FDG-PET. Serial contemporaneous 3D and 4D FDG-PET/CT scans were performed at baseline, 14 days and 70 days after a single fraction of 26 Gy SABR. Tumour response was evaluated in 3D and 4D using SUVmax, RECIST and PERCIST criteria. Normal lung radiotoxicity was evaluated using SUVmean within 0–2 Gy, 2–5 Gy, 5–10 Gy, 10–20 Gy and 20 + Gy isodose volumes.Results. In total, 17 patients were enrolled of which seven were ineligible due to interval progression from staging PET to baseline 4D-PET. The mean time between scans was 62 days. At a median follow-up of 16 months, 10 patients with 13 metastases received SABR, with no patient having local progression. The vector of tumour motion was larger in patients with discordant 3D and 4D PET PERCIST response (p < 0.01), with a mean (± SEM) motion of 10.5 mm (± 0.96 mm) versus 6.14 mm (± 0.81 mm) in those patients with concordant 3D and 4D response. Surrounding normal lung FDG uptake at 70 days was strongly correlated to delivered radiation dose (r2 = 0.99, p < 0.01), with significant elevations across all dose levels (p ≤ 0.05), except the < 2 Gy volume (p = 0.30).Conclusions. We demonstrate high rates of interval progression between staging PET scans in patients with oligometastases. We found that tumour response on conventional 3D PET is not concordant with 4D PET for tumours with large motion. Normal lung metabolic uptake is strongly dose dependent after SABR, a novel finding that should be further validated.

Abstract

The palliative and therapeutic roles of radiation therapy for non-small-cell lung cancer are presented. Combination therapies may include chemotherapy and radiotherapy for cancers that cannot be surgically treated.

46. Long-term survival following chemoradiation for inoperable non-small cell lung cancer

Abstract

A study was conducted to evaluate the rate of long-term survival after treatment with chemotherapy combined with radiotherapy for inoperable non-small cell lung cancer. Results indicated that survival rate could be improved for patients with inoperable non-small cell lung cancer when treated by radical chemoradiation alone.
