Ref. | Case history | Methodology | Responserate |
Nakamura et al[46] Case 1 (Japan, 2012) | A 65 yr old man was diagnosed with squamous cell lung cancer one year earlier and was treated by radical surgery. He now has pain in his right shoulder. Radiologic examinations detected osteolytic bone metastasis at the right scapula and multiple lung metastases. ECOG 1 | Radiation Oncologist members of JROSG completed an internet-based survey Presumed trainees were excluded Not anonymous | NR |
Nakamura et al[46] Case 2 (Japan, 2012) | A 65 yr old man was diagnosed with squamous cell lung cancer one year earlier and was treated by radical surgery. He now has back pain. Radiologic examinations detected osteolytic bone metastasis at L1 and multiple lung metastases. There is no evidence of vertebral collapse or spinal or thecal sac compression. ECOG 1 | ||
Nakamura et al[46] Case 3 (Japan, 2012) | Same setting as in case 2 with the addition of paresthesias in a distribution consistent with the L1 dermatome, compatible with neuropathic pain | ||
De Bari et al[47] Case 21 (Italy, 2011) | 68yo woman ECOG 1, right lung cancer in 2005, pT2N1M0 underwent lobectomy -> adjuvant chemotherapy. No previous RT. Negative F/U to today. Lumbar pain (L2-L3) underwent bone scan and spinal MRI, total body CT and CT brain. 3 new liver lesions. Bone scan: multiple sites of pathological uptake. MRI: multiple osteolytic spinal metastases including at symptomatic sites. No clinical or radiologic evidence of SCC and no risk of immediate fracture. VAS: 8 without analgesics, 3 after regular weak opioids | Questionnaires given to ROs attending the national congress at the time of registration and collected at the end of the congress Trainees included Anonymous Prespecified list of dose fractionation schedules provided as answer choices, or ‘other’ Factors influencing dose were sought for each case | 122/300 (40.6%)3 |
De Bari et al[47] Case 41 (Italy, 2011) | 78yo man ECOG 2, left lung cancer in 2007, pT3NOM0 post left pneumonectomy -> adjuvant chemo x6. Negative f/u until today. Sudden thoracic (D5/D6, D10) and lumbar (L4) pain. No clinical signs of cord compression. No other symptomatic sites. MRI spine: multiple spinal secondary lytic lesions. Radiological signs of D10 spinal cord compression. Risk of pathologic fracture at C3. CT body: multiple liver and lung metastases. VAS: 9 without analgesics, 3 after regular opiods analgesics (transdermal fentanyl 50 ug) and prn nSAIDS | ||
Fairchild et al[9] Case 3 (Intl, 2009) | A 55-year-old male was diagnosed with stage IIIA (T3N2) non-small cell lung cancer one year ago, and was treated radically with chemotherapy and thoracic radiotherapy. He now has pain in the lower back, and a bone scan shows a lesion at L3. His pain localizes to an area consistent with L3, and motor and sensory exams are unremarkable. There is a lytic lesion present and evidence of mild vertebral collapse, but no cauda equina or thecal sac compression on MRI scan | Web-based survey distributed to Radiation Oncologist members of ASTRO, CARO and RANZCR Anonymous Trainees, retirees excluded No prespecified list of dose fractionation schedules provided General factors influencing dose were sought (not case-by-case) Bonferroni used | 962/6110 (15.7%) |
Fairchild et al[9] Case 4 (Intl, 2009) | Same setting as in case above, with the addition of paresethesias in a distribution consistent with the L3 dermatome, compatible with neuropathic pain | ||
Chow et al[48] Case 2 (Canada, 2000) | A 45 yr old male was diagnosed with stage IIIA (T3N2) large cell carcinoma of the lung one year ago, and was treated with chemotherapy and thoracic irradiation. He now has pain in his lower back, and a bone scan shows a lesion in the third lumbar vertebra. His pain localizes to an area consistent with L3, and does not radiate. Motor and sensory examinations are unremarkable. A CT scan of this area shows a lytic lesion, but no evidence of compression of the cauda equina or thecal sac | Survey mailed to all ROs in active practice in Canada Excluded retirees or those practicing outside of Canada No mention of including trainees Did not specify whether anonymous No prespecified list of dose fractionation schedules provided Factors influencing dose not explored | 172/300 (57.3%) |
Chow et al[48] Case 3 (Canada, 2000) | Same setting as above, but instead of L3, the lesion is at L1 with no evidence of cord compression. Assume the external beam irradiation to the painful site in L1 would not overlap the previous radiation field | ||
Roos et al[6] Case 3 (Aust/NZ, 2000) | Male, age 63 with disseminated large cell lung cancer and bone scan positive L1-L3, several ribs and skull. There is pain in the upper lumbar spine only and no neurologic dysfunction | Survey distributed to delegates at 1998 Royal ANZ College of Radiologists Annual Scientific Meeting and returned before a presentation on bone pain Anonymous Trainees included Presumed no prespecified list of dose fractionation schedules were provided since cases were designed based on previous surveys Factors influencing dose sought for each case Used Bonferonni correction | 53/114 (46.5%)3 |
Roos et al[6] Case 4 (Aust/NZ, 2000) | Male, age 63 with disseminated large cell lung cancer and bone scan positive L1-L3, several ribs and skull. There is pain in the upper lumbar spine as well as pain and tingling in the right L2 distribution consistent with neuropathic pain | ||
Hartsell et al[49] Case 22 (United States, 1998) | A 45 yr old male was diagnosed with stage IIIA (T3N2) large cell carcinoma of the lung one year ago, and was treated with chemotherapy and thoracic irradiation. He now has pain in his lower back, and a bone scan shows a lesion in the third lumbar vertebra. His pain localizes to an area consistent with L3, and does not radiate. Motor and sensory examinations are unremarkable. A CT scan of this area shows a lytic lesion, but no evidence of compression of the cauda equina or thecal sac | Survey mailed to randomly selected radiation oncologists in United States Factors influencing dose not reported Did not specify whether prespecified list of doses was given Presumed trainees excluded Did not report whether anonymized | 229/362 (63.3%) |
