Whole-body fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET) has been useful in the management of a variety of malignancies. In patients with chemotherapy followed by bone marrow stimulants such as granulocyte colony-stimulating factor and granulocyte-macrophage colony-stimulating factor, the bone marrow will have diffuse, increased FDG accumulation. Therefore, diffuse bone marrow FDG uptake is commonly attributable to the effect of hematopoietic cytokines. However, diffuse bone marrow FDG uptake can also be caused by bone marrow involvement by malignancy. The authors report a patient with diffuse bone marrow involvement of Hodgkin disease that appears indistinguishable from hematopoietic cytokine-mediated FDG bone marrow uptake.

A 23-year-old female patient was diagnosed as having Hodgkin lymphoma (mixed cellularity type, clinical stage III B) in September 2000. She underwent ABVD chemotherapy and irradiation of a mediastinal lesion, resulting in complete remission. However, the disease reoccurred three month after the completion of initial treatment. She was admitted to our hospital for allogeneic stem cell transplantation. Thoractic vertebra, lumbar vertebra and iliac bone lesions were detected by FDG-PET, and a diagnosis of bone marrow infiltration was made. She received re-induction chemotherapy but did not achieve complete remission. A residual lesion in her bone marrow was detected by FDG-PET. She underwent unrelated allogeneic bone marrow transplantation in May 2002. Preconditioning was VP-16, CY and TBI. Engraftment of white blood cells was on day 15. Skin GVHD was detected at the same time and she was treated with steroid hormones, resulting in improvement. No residual mass could be detected by FDG-PET on day 60. However, she suffered from fever on day 80. Aggravation of the disease was revealed and she died from progression of the disease on day 120. FDG-PET is useful for the monitoring disease status and for determining the optimal timing of various treatments.

Use of F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) in patients with known thyroid cancer is well documented, but the role of this imaging modality in the initial workup of a thyroid nodule has not been defined. The incidental finding of a hypermetabolic focus in the thyroid on F-18 FDG PET in patients with a variety of primary malignancies is reported. Based on the authors' literature search, this is the first documented case of a thyroid cancer resulting from papillary carcinoma detected in a patient with a history of non-Hodgkin lymphoma.

The occurrence of a sarcoidosis associated with Hodgkin's disease is an infrequent but well-described event. Moreover it has been described for many decades that some malignancies may present with simultaneous granulomatous manifestations named sarcoid-like reactions. To differentiate sarcoidosis from the sarcoid-like reactions is not an easy step in the final diagnosis. No author in the past has included the use of 2-deoxy-2[18F]fluoro-D-glucose positron emission tomography (FDG-PET) in order to help in this differentiation. We report two patients with Hodgkin's disease complicated with a typical form of sarcoidosis and with diffuse sarcoid-like reactions. We discuss the use of FDG-PET as a tool in the making of the final diagnosis and the difficulties associated with this technique in the interpretation of different hypermetabolic tissues.

The aim of this study was to evaluate the initial staging and restaging of Hodgkin's disease (HD) according to histopathologic subtype (HST) using fluorine-18-deoxyglucose-positron emission tomography (PET). Special attention was paid to the accuracy of PET for detection of bone marrow infiltration (BMI). 44 patients with HD (m:f = 28:16, mean age 36 +/- 15 years) underwent PET; 16 were primary stagings and 28 restaging examinations. PET results were compared with methods of conventional staging including computed tomography (CT) and bone marrow biopsy. Viable tumor tissue was detected by PET in 25/44 cases, 16 nodular sclerosis (NS), 4 mixed cellularity (MC), 3 lymphocyte predominance (LP) and 2 cases with a nonclassified subtype (NC). FDG tumor uptake, measured as standard uptake value (SUV), ranged from 1.7 to 13. Maximum SUV in NS was 5.2 +/- 1.5 (2.5-7.3), 3.2 +/- 2.4 for MC, 2.6 +/- 0.7 for LP, and 9.1 +/- 3.8 for NC, respectively. In 7% of all patients (3/44) bone marrow infiltrations were detected by PET. PET is known for its superior detection of viable tissue in HD. In this study it was shown that HST does not influence the intensity of glucose metabolism, although 2 patients with NC showed the highest SUVs. In addition PET accurately detected focal BMI and may thus be applied before BMB to guide its optimal use.

In this prospective study, staging of Hodgkin's disease with 18-FDG PET was compared to CT, needle biopsy and staging laparotomy. Forty nine patients with Hodgkin's disease were studied; forty five with new disease and four being restaged for recurrent disease. Thirty eight patients had confirmation by needle or excisional biopsy, eleven by staging laparotomy including needle biopsy. Sensitivity, specificity, positive and negative predictive values of FDG PET were 100%, 100%, 100% and 100% in the laparotomy group. CT values were 20%, 83%, 50% and 56% in the same group. Overall in both surgical and non surgical patients FDG PET changed stage in 59% (29/49) of patients. FDG PET is a safe and effective method of staging Hodgkin's disease.

In contrast to conventional imaging modalities, positron emission tomography using fluorodeoxyglucose detects malignant tumors by their increased glucose metabolism. In patients with Hodgkin's disease or non-Hodgkin's lymphoma, FDG-PET imaging has been shown to sensitively identify enhanced tracer uptake in involved lymph nodes and infiltrated tissue. This brief review will summarize the currently available information on staging of lymphoma patients in comparison with other imaging modalities. In addition, FDG PET imaging has been suggested for differentiation of viable residual or recurrent tumor and scar after tumor therapy. One of the most promising applications of PET in the future will be the metabolic evaluation of early response to tumor therapy. It is hypothesized that changes in tumor metabolism occur before significant decrease of tumor mass. Early assessment of chemotherapy might help to avoid the toxicity of an ineffective therapy. In summary, the results concerning various clinical applications of PET imaging are encouraging for further prospective trials to document the advantage of PET in diagnosis and therapy of lymphoma patients as compared to conventional strategies.

This study was designed to determine the value of 2-[fluorine-18]-fluoro-2-deoxy- d-glucose positron emission tomography (FDG-PET) in the early assessment of therapy response in lymphoma patients. We studied 20 patients with pathologically proven lymphoma, including 17 patients with aggressive non-Hodgkin's lymphoma and three patients with Hodgkin's lymphoma. All patients underwent whole-body FDG-PET imaging at baseline and after 1-2 cycles of chemotherapy. PET images were analysed visually and quantitatively by calculating the standardised uptake value (SUV). In each patient, we measured the SUV of the tumour demonstrating the highest FDG uptake at baseline study and the SUV of the same tumour after 1-2 cycles of therapy. The achievement of complete response was assessed on the basis of a combination of clinical findings and the results of conventional imaging modalities. Follow-up of progression-free survival (PFS) was obtained for the validation of PET data. Of the 20 patients, ten achieved complete remission at the completion of chemotherapy and the other ten did not respond to chemotherapy. Of the ten responders, four are still in remission (PFS 24-34 months) while the other six have relapsed (PFS 8-16 months). For the prediction of 24-month clinical outcome, visual analysis of PET after 1-2 cycles showed high sensitivity (87.5%) and accuracy (80%) but low specificity (50%). Comparison with the baseline SUVs revealed that the responders showed a significantly greater percent reduction in SUV after 1-2 cycles of therapy as compared with the non-responders (81.2%+/-9.5% vs 35.0%+/-20.2%, P<0.001). In addition, using 60% reduction as a cut-off value, the responders were clearly separated from the non-responders, with the exception of one non-responder. In conclusion, when performed early during chemotherapy, FDG-PET may be predictive of clinical outcome and allows differentiation of responders from non-responders in cases of aggressive lymphoma.

The accurate staging of Hodgkin's disease (HD) and non- Hodgkin's lymphoma (NHL) is an important aspect of treatment. In this study, the authors undertook to prospectively evaluate the clinical value of 2-(fluorine-18)fluoro-2-deoxy-D- glucose position emission tomography (FDG-PET) for the staging of malignant lymphoma as compared with computed tomography and 67Ga scan. Thirty consecutive cases with biopsy-proven lymphoma (4 HD, 26 NHL) were examined by FDG-PET for the initial staging and the restaging work-up between September 2000 and April 2001. The FDG-PET and conventional study, including a CT of the neck, chest, abdomen, and of the pelvis, a bone scan, a 67Ga scan, and a bone marrow study were undertaken to investigate nodal/extranodal manifestations and bone marrow infiltration. In terms of the detection of nodal lymphoma manifestation, the sensitivities and specificities of the PET, CT, and 67Ga scan were determined to be 93.3%, 98.9%, and 25.8%, and 100%, 99.1%, and 99.8%, respectively. In terms of the detection of extranodal lymphoma manifestation, the sensitivities and specificities of the PET, CT, and 67Ga scan were 87.5%, 87.5%, and 37.5%, and 100%, 100%, and 100%, respectively. The FDG-PET proved to be very accurate for the staging of malignant lymphoma and superior to Ga-67 scan. Although the results of PET and CT were substantially comparable, both imaging studies were found to complement each other in some cases with respect to the evaluation of lymphomatous involvement.

The prognosis for children and adolescents with Hodgkin's lymphoma is excellent. However, many patients will show secondary malignancies 15-30 years after the initial diagnosis, which appears to be connected with the intensity of treatment during primary disease. In the GPOH-HD 95 trial, the indication for radiotherapy was limited to patients who did not show a complete remission after chemotherapy, as determined radiographically. In the future protocol, the indication for radiotherapy in patients with early-stage Hodgkin's lymphoma should be further refined by using FDG-PET for evaluating the response to chemotherapy. Furthermore, in patients at an advanced stage of the disease, it should be determined if sequential FDG-PET research during chemotherapy can separate patients into subgroups with an excellent or a poor prognosis. This article gives a review of the current literature on FDG-PET in patients with Hodgkin's lymphoma and outlines the consequences for future protocols.
