ABSTRACT
A 71-year-old man with malaise, anorexia, and weight loss was referred to our hospital from a clinic. Abdominal computed tomography(CT)revealed bilateral adrenal masses. An ultrasound-guided percutaneous needle biopsy of the adrenal grand indicated diffuse large B-cell lymphoma. A rapid adrenocorticotropic hormone(ACTH)test revealed primary adrenal failure. Rituximab-cyclophosphamide/doxorubicin/vincristine/prednisolone(common name, R-CHOP)therapy accompanied by intrathecal treatment was initiated along with steroid replacement therapy. After the fourth courses, a CT scan showed a reduction of the adrenal masses, and there was no[18F]-fluorodeoxyglucose(FDG)uptake in the adrenal masses. The patient has remained in metabolic complete remission. Subsequently, both adrenal lymphomas were irradiated. The patient has been disease-free for 6 months after the diagnosis of primary adrenal lymphoma. The combined modality of chemoradiation therapy plus intrathecal treatment could be effective for primary adrenal lymphoma with a poor prognosis.

A 68-year-old man complained of dizziness and was referred to our hospital by his primary physician for evaluation of an elevated leukocyte count. In April 2002, soon after the chronic phase of chronic myeloid leukemia had been diagnosed, he was treated with imatinib. In March 2010, imatinib treatment was completed and the BCR/ABL fusion gene had become undetectable by real time quantitative PCR. Subsequently, leukocyte counts and the hematocrit gradually rose. In August 2012, a bone marrow aspirate showed hypercellular marrow with marked erythroid hyperplasia and the presence of the JAK2 gene V617F mutation. He was diagnosed with polycythemia vera. Phlebotomy and chemotherapy were started in addition to imatinib administration. Shortly thereafter complete blood counts returned to normal levels.

Hepatic involvement by chronic lymphocytic leukemia(CLL)is common, but rarely presents with liver injury. We report a case of chronic hepatitis C(CH-C)in a patient who had suffered from liver injury as a result of hepatic involvement by CLL. A 74-year-old man was hospitalized because of an examination confirming him positive for leukocytosis. Computer tomography scan showed mild hepatosplenomegaly, lymph node swelling of the neck and axilla, and abdominal lymphadenopathy. He was diagnosed as CLL by bone marrow examination. His laboratory data revealed hepatis C virus(HCV)antibody-positive, and elevated levels of both aminotransferase and HCV-RNA. Liver biopsy demonstrated significant CLL involvement of portal areas and a mild T lymphocyte invasion of centrilobular and portal areas. After treatment with polyethylene glycol interferon (PEG-IFN)-α-2b for CH-C, the CLL count was decreased in both peripheral blood and the liver. The hematological response was significantly correlated with the disappearance of HCV-RNA. The patient has maintained a sustained virological response(SVR)status for the past 9 months after PEG-IFN-α-2b administration. Thus, PEG-IFN-α-2b therapy could be effective not only for CH-C but also for hepatic involvement of CLL as seen in our patient.

PURPOSE: On the basis of the results of our preliminary trial suggesting that aberrant crypt foci (ACF) could be eradicated by short-term administration of sulindac, in the present study, we explored the feasibility of using ACF as surrogate markers for chemoprevention of colorectal cancer. EXPERIMENTAL DESIGN: Randomly assigned to sulindac (300 mg daily), etodolac (400 mg daily), and placebo groups were 189 subjects without polyps or who had undergone polypectomy. Drugs were administered for 2 months. ACF in the rectal region were counted by magnifying endoscopy. Occurrence of polyps was evaluated at 12 months. A planned interim analysis was conducted. RESULTS: ACF number at 2 months was significantly suppressed in the sulindac group (P = 0.0075), but not in the etodolac group (P = 0.73). In the sulindac group, the numbers of adenomas plus hyperplastic polyps (total polyps) and adenomas at 12 months were significantly (P = 0.02) and marginally (P = 0.064) lower, respectively, in comparison with the placebo group; no such difference was observed in the etodolac group. In analysis of only polypectomized subjects, the numbers of total polyps and adenomas in the sulindac group were even more markedly lower, with P values of 0.014 and 0.034, respectively. A similar tendency was confirmed by analyses of the incidence of polyps at 12 months. Suppression rates of total polyps and adenomas in ACF responders to sulindac were significantly greater than in nonresponders. In all groups, compliance was more than 90% and no intolerable adverse effects were observed. CONCLUSIONS: ACF may be useful as surrogate lesions for chemoprevention of colorectal cancer.

The development of an unusual case of primary pleural effusion in a 90-year-old human immunodeficiency virus (HIV)-negative Japanese woman with no identifiable tumor mass has been described. Pleural effusion specimens contained large diffuse lymphoma cells, with the phenotype and genotype of a B-cell lineage (positive for CD20, CD79a and clonal rearrangement of Ig heavy chain) and the c-myc gene rearrangement, but were negative for T-cell markers (CD45RO and CD3). The patient was negative for human herpes virus 8 (HHV8), Epstein-Barr virus (EBV) and hepatitis C virus (HCV), as well as human T-cell lymphotropic virus type-1 (HTLV-1). The patient died of respiratory failure 5 months after the diagnosis of primary effusion lymphoma (PEL), and an autopsy was performed. Autopsy findings revealed no evidence of tumor mass or bone marrow involvement of lymphoma cells. This case has been considered as a PEL in a HIV-, HHV8-, EBV- and HCV-negative patient. Although cytomorphology of lymphoma cells was classified as large-cell lymphoma in this case, it is interesting that the present case may represent an unusual subset of Burkitt-like disease because of clear B-cell phenotype and c-myc gene rearrangement.

A 38-year-old woman presented to our hospital with the chief complaint of dyspnea. A chest radiograph showed pleural effusion of the right lung and a CT scan revealed liver metastasis. A tumor biopsy done under bronchoscopy revealed large-cell carcinoma of the lungs. She was given 4 courses of a combination therapy consisting of CDDP (80 mg/m2) and vinorelbine (25 mg/m2). The primary tumor in the right lung and liver metastasis were markedly reduced in size and a partial response was obtained. The combination therapy of CDDP and vinorelbine may become a standard chemotherapy for advanced non-small cell lung cancer.
