A 43-year-old man with refractory myeloma underwent allogeneic bone marrow transplantation from his HLA-matched sibling. He was conditioned with TBI (12 Gy) followed by melphalan (140 mg/m(2) ). Immediately after conditioning was initiated, he began complaining of severe lumbago, and the level of serum calcium rose from 2.25 to 3.34 mmol / l. However, the biochemical markers for tumor-lysis syndrome such as potassium, uric acid, and lactic dehydrogenase remained unchanged. Hydration with saline and pamidronate were started, but he developed acute renal failure requiring hemodialysis for 3 weeks. His plasma parathyroid hormonerelated protein (PTHrP)-NH2-terminal (3.9 pmol/l) and serum PTHrP-C-terminal (125.0 pmol / l) levels markedly increased immediately after conditioning. These results suggested that the increased release of PTHrP from myeloma cells, which resulted from destruction of myeloma cells by conditioning, was the primary contributes to the occurrence of hypercalcemia. We should be aware of the occurrence of hypercalcemia when high-dose therapy is to be given to patients with refractory myeloma.

A 78-year-old woman was admitted to our hospital because of lumbago and appetite loss. Blood analysis revealed anemia, hypercalcemia and circulating plasma cells. Bone marrow aspiration showed an elevated ratio (43%) of plasma cells, which expressed CD38 in the absence of CD19 and CD56 expression. Spinal MR imaging revealed multiple compression fractures and suggested diffuse invasion of plasma cells into the spinal bodies. No M-protein was detectable in serum or urine by immunoelectrophoresis and immunofixation, but cytoplasmic M-protein (IgG-kappa) was detected by enzyme antibody staining. On the basis of the history and data, nonsecretory primary plasma cell leukemia was diagnosed. First, the patient was given modified VAD therapy (vincristine, doxorubicin, and prednisolone) and complete remission was obtained. Then MP therapy (melphalan and prednisolone) was instituted, and remission has since been maintained for 11 months. Like many other cases of primary plasma cell leukemia, this case suggests that CD56 may act as an adhesion molecule between neoplastic plasma cells and bone marrow stromal cells. Our experience with this exceedingly rare case suggests the superiority of combination chemotherapy as an induction therapy and the effectiveness of MP therapy as maintenance therapy for this disease.

A 75-yr-old male simultaneously having lymphoplasmacytic lymphoma (LPL) and diffuse large B-cell lymphoma (DLBCL) is presented. He had manifested with lumbago, high-grade fever, and confusion. Physical examination on admission showed disorientation and severe back pain. There were neither lymphadenopathy nor hepatosplenomegaly. Routine laboratory tests showed moderate pancytopenia, hypercalcemia (serum calcium, 15.9 mg/dL), IgM lambda-type monoclonal gammopathy (IgG, 405 mg/dL; IgA, 42 mg/dL; and IgM, 2023 mg/dL), and lambda-type Bence-Jones protein in the urine (0.8 g/d). Bone marrow biopsy showed the clusters of surface lambda-positive small-sized mature-appearing lymphoplasmacytoid cells. Bone survey and computed tomographic scan showed multiple osteolytic lesions and a tumor involving the third lumbar spine (L3). An open biopsy of the L3 tumor showed diffuse proliferation of CD20- and lambda-positive large cells. We thus diagnosed the patient as simultaneously having LPL and DLBCL. Although the combination chemotherapy was at least partially effective, he died of bacteremia and organ failure after three courses of chemotherapy. To clarify the clonal relatedness between LPL and DLBCL, we analyzed the sequences of the complementarity-determining region 3 in immunoglobulin heavy-chain genes. The data showed that LPL and DLBCL in the present patient originated from two independent clones.

A 54-year-old man with general fatigue and lumbago was admitted for further examination of hypercalcemia and leukocytosis. CT showed a huge renal tumor and extension of the tumor thrombus to the inferior vena cava (IVC). Moreover, the serum granulocyte colony-stimulating factor (G-CSF) and the C-terminal of parathyroid hormone-related protein (PTHrP) were elevated. Under the diagnosis of advanced renal tumor, we performed nephro-ureterectomy and throbectomy. Pathological examination revealed squamous cell carcinoma of the renal pelvis. To our knowledge, this is the first case in Japan that of the simultaneous production of G-CSF and PTHrP in squamous cell carcinoma of the renal pelvis accompanied with IVC thrombus.

A 65-year-old male with IgG-kappa multiple myeloma was treated with melphalan-prednisolone (MP) and obtained a minimal response. Five months after the initiation of MP, he developed back pain, renal failure, hypercalcemia and increased plasma cells in the bone marrow. He was treated with bortezomib. After 2 cycles, he developed a peripheral neuropathy, and the dose of bortezomib was decreased to 1.0 mg/m(2). After 5 cycles, serum monoclonal protein was not detected by immunofixation, and the percentage of bone marrow plasma cells decreased to less than 5%. In March 2007, he developed lumbago again, and MRI of the lumbar vertebrae showed a tumor at the para pediculus arcus vertebrae. Immunohistochemistry of the biopsied tumor demonstrated monoclonal plasma cell infiltration. The patient was treated with local radiation therapy. Bortezomib is a new and effective agent for refractory/relapsed multiple myeloma. It has also been reported that bortezomib is effective for solitary extramedullary plasmacytoma (EMP). However, in the patient reported here, although bortezomib induced a complete response with regard to the serum monoclonal protein and the percentage of bone marrow plasma cells, EMP developed in the parapediculus arcus vertebrae. Herein, we document a case of EMP development during successful bortezomib therapy.

This report presents a case of pancreatic neuroendocrine cell carcinoma with multiple liver metastases secreting gastrin and parathyroid hormone-related protein (PTHrP) related to lumbar bone fracture and hypercalcemia. A 58-year-old woman visited an affiliated hospital with a chief complaint of lumbago without any evidence of trauma. She was diagnosed with hepatic dysfunction and hypercalcemia as well as multiple lumbar compression fractures without osteolytic lesions. Abdominal computed tomography (CT) showed a hypervascular mass in the pancreatic tail and multiple liver tumors. Duodenal ulcers were found with gastrointestinal endoscopy. There was a marked increase in the serum gastrin level. She was diagnosed as gastrinoma with multiple liver metastases and was admitted to the hospital. She had an increase in serum PTHrP level without the elevation of intact parathyroid hormone at the time of admission. She underwent an extended right hepatectomy in addition to a distal pancreatectomy with a regional lymphadenectomy and splenectomy. The postoperative course was uneventful, and serum gastrin and PTHrP activities reduced to normal levels. She remained symptom-free, and serum calcium, gastrin, and PTHrP levels remain within the normal ranges 19 months after surgery without adjuvant therapy.

Cancer patients with bone metastases are at risk of a variety of skeletal events, including vertebral compression and pathologic fractures. Approximately 30% to 40% of patients with advanced lung cancer will develop bone metastases in the course of their disease, resulting in a significant negative impact on both morbidity and survival. Skeletal complications of bone metastases include pain, pathologic fractures, spinal cord compression, and hypercalcemia. The spine is the most frequent site of skeletal metastases. We present a 48-year-old female with intractable and incapacitating low back pain because of metastatic bone tumor in the left lateral side of S1 and S2 with left sacroiliac invasion. Imaging identified a metastatic invasion of the sacrum. Percutaneous sacroplasty, a safe and effective procedure for sacral-insufficient fractures, was performed under fluoroscopy guidance. However, the expected pain relief was not achieved. At 1 month, the patient remained invalided by severe back pain, which was localized to the left sacroiliac joint. In a second procedure, the sacroiliac joint was cemented. Pain relief was complete, immediate, and sustained until the patient's death related to the underlying oncologic disease. No complications were observed. Few reports exist about the treatment of sacral metastatic tumors with percutaneous sacroplasty. Further, no previous reports about sacroiliac joint cementation for joint stabilization have been found. In the present case, sacroiliac joint cementation successfully resolved residual pain that remained despite percutaneous sacroplasty treatment of the pathologic sacral fracture.

Immunoglobulin D (IgD) myeloma is a rare subtype and it is widely accepted as an aggressive disease. Here, we report a 66-year-old woman with IgD myeloma who had anemia, lumbago, multiple osteolytic lesions and hypercalcemia. The patient refused a blood transfusion because of her beliefs, so we administered bortezomib and dexamethasone (BD) after high-dose dexamethasone therapy. Marked improvement of anemia and elevated serum alkaline phosphatase levels was recognized. After 5 cycles of BD therapy, the patient achieved a stringent complete response according to International Myeloma Working Group Response Criteria. BD therapy might be a feasible and useful treatment option for IgD myeloma.

Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent episodes of painful inflammation in the abdomen, chest, or joints. The coexistence of multiple myeloma (MM) and FMF is an extremely rare event. Here, we report a case of FMF with concurrent MM. A 63-year-old woman was diagnosed with FMF since 15 years earlier. She was admitted with a complaint of low back pain. Regarding the presence of back pain, anemia, hypercalcemia, and kidney failure, a diagnosis of MM was suspected. A skeletal survey showed punched-out lesions in the skull. Serum protein electrophoresis demonstrated an immunoglobulin G kappa monoclonal gammopathy, and bone marrow aspiration revealed 30% involvement by abnormally appearing plasma cells, suggestive of MM. Although the association between FMF and MM may be a mere coincidence, further studies are necessary to understand their concurrent development.
