Comparative Study[Comparison of preliminary results of involved-field with extended field radiotherapy combined with chemotherapy for early stage Hodgkin's disease].
To evaluate whether involved-field (IF) radiotherapy is equally effective and less toxic in comparison with extended-field (EF) radiotherapy for patients with early-stage Hodgkin's disease (HD) who received combined modality therapy. ⋯ Compared with extended-field radiotherapy, involved-field radiotherapy is equally effective and less toxic for patient with early-stage Hodgkin's disease treated with combined modality therapy.

Randomized Controlled Trial[Evaluation of Gd-BOPTA and Gd-DTPA in contrast-enhanced MR imaging of the liver].
To evaluate the safety, tolerance and efficacy of Gd-BOPTA and Gd-DTPA in contrast-enhanced MR imaging of the liver. ⋯ The early post-contrast phase of Gd-DTPA-enhanced MR imaging is superior to delayed phase. The effects of Gd-BOPTA and Gd-DTPA in early post-contrast imaging are comparable, but Gd-BOPTA is significantly superior to Gd-DTPA in delayed post-contrast imaging.

[Perioperative management for primary tracheal malignant tumors resected under cardiopulmonary bypass].
To retrospectively review the perioperative management for primary tracheal malignant tumors resected under cardiopulmonary bypass. ⋯ Resection of primary tracheal malignant tumors with severe tracheal obstruction under cardiopulmonary bypass is practicable. Keeping respiratory airway patent perioperatively is very important and helpful to postoperative recovery.

[Impact of PET/CT on precise radiotherapy planning for non-small cell lung cancer].
To investigate the impact of PET/CT on the clinical staging, target volume delineation and precise radiotherapy (PAR) planning for patients with non-small cell lung cancer (NSCLC). ⋯ 1. The impact PET/CT on clinical staging of NSCLC and PAR planning was remarkable. 2. PET/CT is more consistent with pathology in staging than CT and, therefore, is an important compensatory staging measure. 3. Compared with CT, PET/CT can reduce the V(GTV) in patients with atelectasis and obstructive pneumonitis when contouring the target volume, so can provide better protection for normal surrounding lung tissue. On the other hand, PET/CT is more sensitive in detecting mediastinal lymph node metastasis than CT, and the V(GTV) can be more precise and guaranteed. 4. Radiopneumonitis may be more effectively prevented because of significant decrease in V(20) and MLD by more precise planning based on PET/CT results. 5. PET/CT not only can provide satisfactory Ds, TCP and NTCP within clinical demand, but also more precise delineation of the radiation target volume and precise radiotherapy planning for NSCLC.
