A 76-year-old man presents with back pain and malaise purchase 50mg caverta with amex erectile dysfunction statistics singapore. Initial laboratory results are as follows: WBC buy 100mg caverta otc erectile dysfunction pump uk, 3,000/µl; hematocrit, 28%; platelet count, 200,000/µl. Serum protein electrophoresis (SPEP) reveals a monoclonal protein level of 3. Bone marrow evaluation reveals sheets of dysplastic plasma cells, and skeletal survey reveals osteolytic lesions in the skull and vertebrae. Interferon alfa Key Concept/Objective: To understand the role of bisphosphonates in the treatment of multiple myeloma This patient has most of the classic symptoms of multiple myeloma, including plasma cell infiltration of the bone marrow, osteolytic bone lesions, anemia, and an M protein level of greater than 3. Chemotherapy with melphalan and prednisone is a reason- able therapeutic option because this combination has been shown to have a higher response rate than monotherapy with either drug. In patients who have bone disease, pamidronate is added to provide protection against skeletal complications; this approach appears to improve quality of life and possibly provides a survival advantage. Therefore, current recommendations are to add bisphosphonates such as pamidronate to the regi- mens for all patients with evidence of bone involvement. A 74-year-old white woman presents to you in clinic for routine follow-up. Her medical problems consist of hypertension and mild degenerative joint disease, for 12 ONCOLOGY 39 which she is receiving hydrochlorothiazide and nonsteroidal anti-inflammatory drugs (NSAIDs) as need- ed. On her last visit, her only complaint was of increasing fatigue, which she had been experiencing for several months. Results of routine laboratory tests at that time were as follows: white blood cell count, 7,500 cells/µl; hematocrit, 26%; mean cell volume, 96 fl; and platelet count, 485,000/µl. Follow-up lab- oratory studies revealed no vitamin B12 or folate deficiencies. Repeat laboratory values today reveal a persistent macrocytic anemia and an elevated platelet count. The presence of monolobulated and bilobulated micromegakaryocytes characterizes which of the fol- lowing chromosomal abnormalities? A deletion of the long arm of chromosome 9 Key Concept/Objective: To know the clinical presentation of myelodysplastic syndrome (MDS) Considerable data suggest that MDS results from combined defects of both stroma and hematopoietic stem cells. Several clinical syndromes that may have a more predictable natural history can now be defined. For example, a deletion of the long arm of chromo- some 5 can be detected in some older patients, especially women, with a macrocytic, refractory anemia (RA). The bone mar- row picture in the RA with 5q– syndrome is characterized by the presence of monolobu- lated and bilobulated micromegakaryocytes. Two thirds of these patients have RA or RA with ringed sideroblasts (RARS), and the remainder have RAEB (RA with excess of blasts). In those patients who have a del(5q) as their sole cytogenetic abnormality, MDS tends to follow a more benign course, although progression to acute myeloid leukemia (AML) may occur. A 62-year-old woman well known to you comes to see you in clinic. Since the last time you saw her, she was admitted to the hospital and diagnosed with acute leukemia. She has been followed by a local hema- tologist and has undergone remission-induction chemotherapy. She is scheduled to begin postinduction consolidation therapy. She explains that she and the specialist are working toward a “complete remis- sion” (CR) and wants to know if that means she will be cured. Which of the following definitions of CR is most accurate? Full recovery of normal peripheral blood counts; blast cells are unde- tectable in the bone marrow B.
