Severe disseminated varicella zoster virus (VZV) infection rarely occurs in patients who are not recipients of hematopoietic stem cell transplantation. This report concerns severe disseminated VZV infection in a diffuse large B cell lymphoma (DLBCL) patient treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). The patient was an 82-year-old male with DLBCL who had a history of type II diabetes mellitus. He incurred VZV infection with severe hepatitis and disseminated intravascular coagulopathy after three courses of R-CHOP. When the VZV infection occurred, anti-VZV IgG was not detected and lymphopenia was observed. We initiated treatment with acyclovir, immunoglobulin, and thrombomodulin alpha, and rescued this patient. We suggest that the use of chemotherapy for immune-suppressed elderly lymphoma patients may involve the risk of severe VZV infection.

We present a case of advanced HER2-positive male breast cancer, which showed a good response to a combined treatment of trastuzumab and paclitaxel. A 78-year-old man was diagnosed with invasive ductal carcinoma (T4d N3 M1, stage IV). He had advanced breast cancer consisting of multiple tumors with skin involvement and redness over the entire left chest region. A computed tomography (CT) scan of the chest revealed a metastatic tumor in the left lung. Histologically, both the primary breast cancer and the metastatic lung tumor were identified as invasive ductal carcinoma that was estrogen receptor-negative (ER)(-) and progesterone receptor-negative (PgR)(-), with a HER2 score of 3+ (IHC). The patient received a combination chemotherapy using trastuzumab and paclitaxel. Two months later, a follow-up chest CT scan showed that the left lung tumor had disappeared, suggesting a good response to trastuzumab and paclitaxel. During trastuzumab treatment, no severe adverse events above grade 3 were observed. This is the first reported case of advanced HER2-positive male breast cancer in which a good response to trastuzumab and paclitaxel was demonstrated at both primary breast cancer and metastatic sites.

To examine the prognostic significance of minimal residual disease (MRD) in t(8;21) acute myeloid leukemia (AML), 96 bone marrow samples from 26 Japanese patients in complete remission (CR) were analyzed regarding the RUNX1/MTG8 transcript using real-time reverse transcriptase polymerase chain reaction assay. All patients were treated with intensive chemotherapy. The median copy number of the RUNX1/MTG8 transcript, measured after each treatment course decreased over time. However, an increase in the MRD level was documented in three patients after the second consolidation, and all of them subsequently relapsed. The relapse-free survival (RFS) did not differ between the patients whose MRD levels were below or above 1,000 copies/microg after the first consolidation, with respective 2-year rates of 62 and 86% (P = 0.21). With respect to the MRD level after induction therapy, our data also failed to show any favorable effect of a lower MRD on RFS. Although these findings need to be confirmed with a larger number of patients, our data indicate that the MRD level at a given time during the early course in CR does not predict the outcome in Japanese patients.

To examine the efficacy of intensified maintenance chemotherapy, we conducted a prospective multicenter trial in adult patients with newly diagnosed acute promyelocytic leukemia treated with all-trans retinoic acid and chemotherapy. Of the 302 registered, 283 patients were assessable and 267 (94%) achieved complete remission. Predicted 6-year overall survival in all assessable patients and disease-free survival in patients who achieved complete remission were 83.9% and 68.5%, respectively. A total of 175 patients negative for PML-RARalpha at the end of consolidation were randomly assigned to receive either intensified maintenance chemotherapy (n = 89) or observation (n = 86). Predicted 6-year disease-free survival was 79.8% for the observation group and 63.1% for the chemotherapy group, showing no statistically significant difference between the 2 groups (P = .20). Predicted 6-year survival of patients assigned to the observation was 98.8%, which was significantly higher than 86.2% in those allocated to the intensified maintenance (P = .014). These results indicate that the intensified maintenance chemotherapy did not improve disease-free survival, but rather conferred a significantly poorer chance of survival in acute promyelocytic leukemia patients who have become negative for the PML-RARalpha fusion transcript after 3 courses of intensive consolidation therapy.

Thirty-two adults (median age 48 years) with acute myelogenous leukemia (excluding M3) have been treated with short-term intensive therapy (M90 therapy). After induction therapy with daunorubicin, cytosine arabinoside (araC), 6-mercaptopurine, prednisolone, mitoxantrone (MIT) and etoposide (VP16), three regimens of post-induction chemotherapy were conducted as short an intercycle time as possible. The first regimen was with MIT and VP16, the second with behenoyl-araC and aclarubicin and the third with VP16, araC, vincristine and vinblastine. No further therapy was given. Complete remission was achieved in 24 (75%) of 32 patients and 24% of all patients were projected to remain free of disease at 5 years. The median duration of the entire therapy was 120 days with a range of 95 to 157 days. Post-induction regimens resulted in severe myelosuppression and their toxicity included treatment-related death in one patient. The treatment results of this short-term therapy were comparable to a former treatment protocol, M84 therapy with a median duration of the entire treatment therapy of 515 days. To confirm the advantages of such short-term therapy, prospective randomized comparisons with conventional post-induction therapy may be required.

In order to analyse the clinical characteristics and outcome in acute myelogenous leukemia, 129 consecutive adult patients admitted to our hospital over a 10-year period, from August 1984 to July 1994, were studied. Their median age was 51 years, 17 (13.2%) of them had antecedent myelodysplastic syndrome (MDS) and 9 (7.0%) had secondary leukemia. Seventy-eight patients (60.5%) were considered eligible for cure-oriented intensive chemotherapy. Forty-four patients were ineligible of one or more of the following; age over 70, antecedent MDS or secondary leukemia. Additional 7 patients were excluded due to concurrent severe diseases. The median survival of the 129 patients was 441 days with an actuarial 5-year survival of 28.6 +/- 4.4%, and the disease-free survival (DFS) decreased with the increasing age of the patient. In 78 patients who were eligible for intensive chemotherapy, complete remission was achieved in 84.6% and overall DFS was 41.1 +/- 5.9% at 5 years, and their survival was longer than that of ineligible patients. It was suggested that considerable selection of patients, for example, due to old age, already existed before visiting our hospital. Analysis of clinical data of unselected patients might enable the development of a rational approach to the management of elderly patients.

We have developed a new combination intravenous chemotherapy regimen called COMPA (IV-COMPA). The clinical value of IV-COMPA chemotherapy was evaluated based on the results of 24 patients with urothelial cancers. From October 1989 through October 1993, a total of 24 patients (20 males and 4 females) received IV-COMPA chemotherapy at Tokyo Medical College Hospital and Tokyo Medical College Hachioji Medical Center. All patients had advanced transitional cell carcinoma or adenocarcinoma of the urothelial tract (renal pelvis, ureter or bladder). One course of IV-COMPA was delivered at 2-week intervals and consisted of 30 mg/m2 CDDP on day 4 and 5, 0.6 mg/m2 VCR (Oncovin) on day 1 and 2, 5 mg/m2 MTX on day 2 and 3, 5 mg/m2 PEP on day 1, 2 and 3, 20 mg/m2 ADM on day 4. A few patients received the same regimen without peplomycin called IV-COMA to avoid pulmonary fibrosis. Fifteen patients with surgically confirmed invasive carcinoma were defined by at least 1 of the following criteria: multiple tumors or size greater than 5 cm, grade 3, stage P3 or P4, pN+, pR1, pL1, pV1, or secondary carcinoma in situ. These patients were treated with 2 or 3 corpses of postoperative IV-COMPA chemotherapy to improve prognosis. In this group, 14 of 15 (93%) are alive at a median follow-up of 22 months (range, 8-57 months) and actuarial survival rates of 1 and 3 years were 100%, 90.9%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

A 60-year-old man visited our hospital with a chief complaint of penile tumor on November 13, 1984. Circumcision of true phimosis was performed and biopsy of the 27 x 27 mm fixed tumor on the glans revealed well differentiated squamous cell carcinoma. Seventy Gy of electron irradiation to the penis revealed a complete response. On February 1, 1985 bilateral inguinal lymph node dissection was performed and revealed metastasis to a left inguinal node. In May 1990, erosive changes occurred on the irradiated region, and local recurrence was confirmed. Since 2 courses of MBD (methotrexate, bleomycin, cisplatin) chemotherapy was not effective, additional wedge dissection was performed. In January 1992, local recurrence was found. Four courses of intra-arterial chemotherapy (cisplatin, vincristine, methotrexate, adriamycin) was performed with a complete response. No evidence of disease has been recognized for more than two years after completion of the treatment.

Seventeen patients with refractory or relapsed, intermediate or high grade non-Hodgkin's lymphoma (NHL) were treated with the combination of dexamethasone (40 mg/body x 3d, iv) (DeVIC) between January and December 1992. The treatments were repeated every three weeks for a minimum of two courses unless the patient had PD. G-CSF (2 micrograms/kg, sc) was given during leukopenia in most cases. Of 16 evaluable patients 6 (38%) achieved a complete remission (CR) and 4 showed a partial remission. With median follow up of 15 (7-26) months (mos.) all CR patients were alive in CR, except for 1 patient who died of secondary AML. The actuarial 50% survival duration after DeVIC was 15+ mos. One patient died of sepsis but myelosuppression was generally moderate and no other serious toxicity was observed. Although this is a preliminary study, DeVIC regimen seems to be an effective salvage therapy for patients with refractory or relapsed NHL with acceptable toxicity.

A case of primary malignant lymphoma of the bladder is reported. A 70-year-old woman was admitted to our clinic with the chief complaint of intermittent gross hematuria on March 31, 1992. Examination of cystoscopy, IVP, ultrasonography and CT scan suggested a non-papillary invasive bladder tumor. Pathological examination of transurethral biopsy revealed malignant lymphoma, B cell type. After 5 courses of intraarterial COMPA (CDDP, VCR, MTX, PEP, ADR) chemotherapy, she have been in complete remission. Intraarterial COMPA chemotherapy might be effective and useful for primary malignant lymphoma of the urinary bladder.

Alternating non-cross-resistant chemotherapy has been induced for the treatment of non-Hodgkin's lymphoma (NHL) with the aim of cure, even in advanced cases. We formulated a new high dose regimen, CAMBO-VIP, which was a weekly treatment. They were administered during alternate weeks for a total period of 12 weeks. We obtained high response rate and prolonged disease-free survival with this regimen. We noticed the elevation of serum LDH level in some patients at or shortly after the completion of CAMBO-VIP treatment. LDH elevation was not associated with liver function abnormality in terms of elevation of GOT or total bilirubin. All of these patients were in complete or partial response with no evidence of tumor progression. An LDH isozyme study which was done at the time of LDH elevation showed elevation of both LDH1 and LDH2. Interestingly serum haptoglobin was undetectable in all 6 patients measured at the time of LDH elevation. Reticulocytosis and leukoerythroblastosis in peripheral blood were also observed in all of these patients. These abnormalities including LDH elevation returned to normal within a rather short period, usually within 1 to 3 weeks. From these observations, it is most likely that these abnormalities were due to excessive blood cell destruction, which was observed in association with rapid recovery from myelosuppression.

Twenty-two patients with advanced diffuse large cell lymphoma (LSG classification) were treated with the combination chemotherapy of cyclophosphamide, doxorubicin, methotrexate with leucovorin rescue, bleomycin, vincristine, etoposide, ifosfamide and prednisolone (CAMBO-VIP) from Oct. 1987 to Sept. 1989. Eighteen (90%) of 20 evaluable patients achieved complete remission and 2 patients had partial remission. With a median follow-up of 52 mos, 3 patients relapsed (17%), and 2 patients died. The actuarial overall survival and relapse-free survival at 4 years were estimated to be 90% and 83%, respectively. Myelosuppression was severe, but transient. No serious infection was seen, and no platelet transfusion was required. Oral mucositis and liver damage (Grade 3 in WHO grading) was seen in one patient each, but no treatment-related fatalities were observed. CAMBO-VIP is a well tolerated, effective treatment regimen for advanced diffuse large cell lymphoma.

Thirty-nine patients with non-Hodgkin's lymphoma were treated with weekly alternating non-cross-resistant chemotherapy (CAMBO-VIP). We obtained a high response rate, and prolonged disease-free survival with side effects and complications of various severity were observed. Three patients were withdrawn from the study due to aggravation of liver cirrhosis, cerebral infarction, and poor tolerance. Thirty-six patients completed this 12-week intensive chemotherapy. The median treatment delay in all patients was 3 days (-4 to 29 days), and a delay of over 15 days was seen in 5 patients. The nadir of the neutrophil count was 0 to 2,100/microliters (median 140/microliters), and 15 patients were below 100/microliters. Two patients had pneumonia and 4 had herpes zoster infection. The platelet count nadir was 20,000 to 240,000/microliters (median 90,000/microliters). Ten patients were below 50,000/microliters, but none required platelet transfusion. Red cell transfusion was given in 6 patients. Elevation of transaminases was seen in 25 patients, but it was not serious except for a patient with liver cirrhosis. The elevation of serum LDH level and decrease of serum haptoglobin level seen shortly after completion of treatment seemed due to the increased blood cell destruction. Stomatitis was observed in 32 patients, 17 of whom showed more than grade 3 toxicity. Blister formation on palms and/or soles was noted in 6 patients. There was no treatment-related death observed.

Three patients with breast cancer with poor prognosis were treated with high-dose chemotherapy (HD-CT) and peripheral blood stem cell transplantation (PBSCT) as adjuvant treatment. After radical mastectomy, the consolidation chemotherapy with Adriamycin 50 mg/m2, Cyclophosphamide 1,000 mg/m2, Vincristine 1.0 mg/m2 and Methotrexate 200 mg/m2 with Leucovorin rescue was started. Recombinant human granulocyte colony stimulating factor (rhG-CSF) was also added for early recovery from myelosuppression. This combination chemotherapy was given every 3 weeks for 3 courses, and after the 2nd and 3rd courses, peripheral blood stem cells (PBSC) were collected and cryopreserved. HD-CT with Cyclophosphamide 2,000 mg/m2/day, Thio-TEPA 200 mg/m2/day, and Etoposide 300 mg/m2/day, were administered for 3 consecutive days, and after 48 hours of last doses, frozen-thawed PBSC (6.4-8.9 x 10(4)/kg of CFU-GM) were administered. rhG-CSF was also added. HD-CT and PBSCT were well tolerated, recovery from myelosuppression of the HD-CT was very quick and no serious side effects were observed.
