Despite the availability of new tools for the quantitative assessment of disease activity on PET/CT, the SUVmax rather than MTV and TLG remains the only predictor for EFS in DLBCL patients. The magnitude of glycolytic activity rather than the amount of metabolically active burden holds a predominant value for determining the response to chemotherapy in DLBCL.

Background:Spinal cord decompression after cervical spinal cord injury (SCI) is the standard of care. However, there is a lack of consensus regarding the optimal management of these injuries, including the role of traction and timing of surgery. Here, we report the safety/efficacy of ventral surgery without preoperative traction for intraoperative fracture reduction following acute cervical SCI.Methods:We prospectively collected a series of patients who sustained acute traumatic subaxial cervical (C3–7) spine fractures between 2004 and 2016. Patients underwent anterior cervical decompression and fusion within 24 h of injury without the utilization of preoperative traction.Results:Thirty-six patients (27 male, 9 female), averaging 35 years of age, sustained 25 motor-vehicle accidents, 4 sports-related injuries, and 7 falls. Fracture dislocations were seen in 26 patients, whereas burst fractures were seen in 10. The majority of injuries occurred at the C4–5 (13 patients) and C5–6 (13 patients) levels. Complete SCI occurred in 10 patients, and incomplete SCI in 26 patients. All patients underwent anterior surgery only; 16 required vertebrectomy in addition to anterior cervical discectomy and fusion. Intraoperative reduction was achieved in all patients using a Cobb elevator or distraction pins without the use of preanesthesia traction. There were no intraoperative complications. Postoperatively, there were one postoperative hematoma, two wound/hardware revisions, one subsequent posterior fusion, and one reoperation anteriorly after screw pullout. The average hospital length of stay was 10.6 days (range 1–39).Conclusion:Early direct surgical stabilization/fusion for acute SCI because of subaxial cervical spine fractures is both safe and effective in selected cases when performed anteriorly without preoperative traction in select cases.

We evaluated the pain response and daily discomfort in patients suffering from a borderline degree of bone pain due to breast or lung cancer bone metastases, who had undergone early palliative radionuclide treatment. The results were compared with those from patients who had received standard analgesic therapy. Twenty-one patients (65.7 ± 3 years; 17 women) with metastatic bone cancer underwent samarium-153 (Sm-153) ethylene diamine tetramethylene phosphonate (EDTMP) administration (group A) and 18 patients (64.3 ± 8 years; 16 women)continued to receive standard analgesics (group B; control group). The patients kept a daily pain diary assessing both their discomfort and the pain at specific sites by means of a visual analog scale, rating from 0 (no discomfort–no pain)to 10 (worst discomfort–pain). These diaries were reviewed weekly for 2 months and three physicians rated the pain response on a scale from -2 (considerable deterioration) to +2 (considerable improvement). Baseline characteristics were similar in both groups. The reduction of total discomfort and of bone pain in group A was significantly greater compared to group B (p < 0.0001). A significant improvement of clinical conditions was observed in group A, where the physician rate changed from -1 to 1, compared to group B in which the rate changed from -1 to 0. Sm-153 EDTMP therapy can be considered for patients with bone pain from breast and lung cancer in advance, i.e.,before the establishment of severe pain syndrome.
