A 59-year-old man diagnosed as a chronic ATL with cutaneous invasion, was treated with small doses of CPM, ADM, VDS and PSL regimens according to CHOP. The treatment was successful and achieved PR at the first stage of the therapy, but it became refractory later. He was then treated with small MEPP (MXT, VP-16, CDDP and PSL) as the salvage therapy for non-Hodgkin's lymphoma. This case suggested that small MEPP might be a useful combination chemotherapy for ATL.

Of those patients with localized (CS I-II) non-Hodgkin's lymphoma of Waldeyer's ring who were treated with radiotherapy or radiotherapy plus chemotherapy and who suffered relapses at the National Cancer Center Hospital over the past 22 years, 24 cases were analyzed on the basis of their response rate and duration of remission with reinduction chemotherapy, and survival time after recurrence. The group [ADM (+)], treated with regimens including adriamycin, was compared with the group [ADM (-)] treated with regimens excluding adriamycin. Complete response was seen in 9 out of 11 cases (81.8%) and in 8 out of 13 cases (61.5%) for the ADM (+) group and the ADM (-) group, respectively (p greater than 0.1). The period of complete response of the ADM (+) and ADM (-) groups was compared using the logrank method. The prognosis of the former was significantly (p less than 0.01) better than that of the latter and the median duration of remission was 30 months and 7 months, respectively. When the survival after recurrence of the ADM (+) and ADM (-) groups was compared, the median survival time was 38 months for the ADM (+) group and 12 months for the ADM (-) group, but no significant difference was observed between the two groups (0.05 less than p less than 0.1).

A phase II clinical trial of a new anthracycline, 4'-O-tetrahydropyranyladriamycin (THP-ADM), was performed in thirty-one patients with advanced malignant tumors refractory to standard chemotherapies. The dosage of THP-ADM was 40 mg/m2 by iv bolus injection repeated every 3 weeks. Of 3 evaluable patients with non-Hodgkin's lymphoma, one achieved partial remission. A minor response was noted in one out of 7 patients with gastric cancer and one out of 5 patients with ovarian cancer. Leukopenia less than 4 X 10(3)/cmm and thrombocytopenia less than 100 X 10(3)/cmm were seen in 81% and 19% of cases, respectively. Mild gastrointestinal toxicities including nausea and vomiting and anorexia were observed in about one third of the patients. Mild hair loss occurred in 2 patients (6%). No ECG abnormalities on clinical sign of cardiotoxicity were seen.

We summarize here the antitumor activity of newly developed drugs against malignant lymphoma. Irinotecan hydrochloride (CPT-11) showed a CR rate of 15% and an excellent response (CR + PR) rate of 42% in patients with non-Hodgkin's lymphoma who had prior treatment. In patients with ATL, 13% achieved CR and a response rate was 39%. MST-16, a new orally administered bis(2, 6-dioxopiperazine) analogue, showed a CR of 3% and PR of 28% (response rate 31%), among patients with ATL, 9% of 23 patients achieved CR and the response rate was 44%. Phase I studies of fludarabine demonstrated a high response rate of 64%, especially in follicular lymphoma, with a number of patients achieving CR. Subsequent phase II studies demonstrated a response rate of 89% in patients with indolent lymphoma. KRN 8602 was developed in an attempt to improve the clinical efficacy of currently used anthracyclines. KRN 8602 has been shown to produce less cardiotoxicity and alopecia, yet has comparable antitumor effects to ADM, and also has demonstrated an antitumor effect on ADM-resistant tumors. CPT-11 and MST-16 were found effective not only in refractory non-Hodgkin's lymphoma, but also in patients with ATL, which had no standard therapy. Fludarabine has been demonstrated to be a very active drug in indolent lymphoid neoplasms, particularly CLL and low grade lymphoma. These new drugs are expected to overcome malignant lymphoma refractory to treatment thus far.

Recent advances in adjuvant chemotherapy for malignant bone tumor have been improving the survival rate and making limb-salvage surgery a reliable technique. Ewing's sarcoma is treated by multiple agent chemotherapy. We treat Ewing's sarcoma by Rosen's T-11 protocol (CYT.ADM.MTX.VCR.ACT-D.BLM). This protocol is very effective, but results are poorer than for osteosarcoma. Newly developed protocols such as EICESS (European Intergroup Cooperative Ewing's Sarcoma Study)-92, including new drugs, should be investigated. The results with malignant fibrous histiocytoma are comparable to those for osteosarcoma. We have performed an original chemotherapy protocol, called "K-1 protocol." Patients were treated with three courses of intraarterial infusion of cisplatin (120 mg/m2) and caffeine (1.0-1.5 mg/m2/day for three days continuously) at two-week intervals. If the effect was insufficient, ADM (30 mg/m2/day for two days continuously) is added to this protocol. We treat malignant lymphoma in collaboration with a hematologist and radiologist. The 5-year survival rate of non-Hodgkin's lymphoma in our series was 56% in clinical stage III and 34% in clinical stage IV. We are trying third-generation chemotherapy to improve the survival rate.

A 71-year-old woman was diagnosed as malignant lymphoma (non-Hodgkin's lymphoma, diffused mixed cell type) which involved gastric lesions. Combined chemotherapies were undertaken using VCR, CPA, 4-epi-ADM and PRED and then etoposide, 4-epi-ADM and PRED. After about 5 months, recurrent lesions were revealed in the right supraclavicular lymph node, so we conducted additional chemotherapy. However, the patient rejected intravenous therapy and required out-patient therapy, so daily oral administration of etoposide (50 mg/day) was carried out. Because of the toxicities of alopecia, the dose was reduced to 50 mg every other day, then to 25 mg every other day. No recurrent signs have been seen for the past 3 years. Bone marrow suppression was little. Chronic oral administration of low-dose etoposide is the potential salvage therapy of gastric malignant lymphoma.

One hundred sixty-three patients with previously untreated stage I/II non-Hodgkin's lymphoma were analyzed as to their in-field and marginal relapse of the irradiated field following treatment with more than 30 Gy of radiotherapy between 1981 and 1995 at Hyogo Medical Center for Adults. Local regrowth in case of partial response was counted as in-field relapse. Complete response was obtained in 94.5% of the cases at the termination of radiotherapy and in 98.8% finally. The ten-year cumulative in-field relapse and marginal relapse rates were 5% and 8.7%, respectively. The cumulative in-field relapse rate (CIFRR) in cases of bulky disease (more than 5 cm in largest diameter of the tumor) was significantly higher than in those of non-bulky disease (26.1% in 8 years vs 2.4% in 10 years, P < 0.01). The radiation dosage delivered (40 Gy = < and 50 Gy > vs 50 Gy < =) a great much difference in cases of bulky disease (23.8% for 8-year CIFRR vs 0% for 1-year CIFRR, respectively), but less difference with non-bulky disease (2.6% vs 2.2%). High LDH and suboptimal dose chemotherapy (three courses and less chemotherapy containing ADM or its derivatives, chemotherapy without ADM or no chemotherapy) had a negative impact on marginal control in aggressive lymphoma. Extended field setting in aggressive lymphoma was not proven to be beneficial in comparison with involved field setting as to marginal field relapse. Thus, it is concluded that (1) higher doses should be given to bulky disease, (2) careful field coverage with enough margin is recommended for aggressive lymphoma with high LDH or treated without optimal dose chemotherapy, and (3) extended field setting is not necessary.

CPT-11 + ADM therapy (CPT-11 40 mg/body x 2 days; Day 1 & 2, combined with ADM 20 to 60 mg/body x 1 day; Day 3) was given to four patients with relapsed and advanced non-Hodgkin's lymphoma, which was refractory to conventional chemotherapies. The symptoms of the patients at the beginning of CPT-11 + ADM therapy were fever (in two cases), dyspnea due to pleural effusion (in two), severe backache (in one), and jaundice with splenomegaly (in one). Their Karnofsky performance scales were 20 or 30%. Soon after the initiation of CPT-11 + ADM therapy, their clinical conditions improved dramatically, and they obtained a partial remission lasting 3.5 to 9 months. During the period of controlling lymphomas by this therapy, all patients had some time at home for 2 to 8 months. The adverse effects were vomiting, diarrhea, neutropenia and thrombocytopenia, but no lethal infection or hemorrhage was seen. We conclude that CPT-11 + ADM therapy is very useful for improvement of QOL and life prolongation of patients with non-Hodgkin's lymphoma, which is refractory to conventional chemotherapies and is even disseminated.

The aim of this study is to verify the feasibility and the clinical activity of a new CHOP-like schedule (ACOD) with a fractionated days 1 and 8 administration in elderly patients. This regimen was chosen in the attempt to allow a sufficient dose intensity (DI) of each drug with better compliance. Fifty-two patients, (74 years, median age), with diffuse large B cell non-Hodgkin's lymphoma were retrospectively evaluated. Patients received ADM 25 mg/sqm, CTX 500 mg/sqm, VCR 1.2 mg/sqm (max 2 mg intravenously) days 1 and 8 and PDN 50 mg orally, days 1-8. Results showed that 54% of patients reached a complete remission, 21% a partial remission with an overall response rate of 75%. Two-thirds of the patients received at least 70% of the planned dose of cyclophosphamide and doxorubicin and 50% of vincristine and prednisone. The median duration of follow up was 12.6 months (range 0.7-61.4). The estimated median OS was 15.2 months (95%CI = [11.6, not estimable]); the estimated median PFS was 5.7 months (95%CI = [5.12, not estimable]). After 2 years, the proportion of patients alive was 47% (95%CI = 34-64%) and the proportion of patients free from progression was 39% (95%CI = 27-57%). Grade 3-4 leukopenia was observed in 61% of patients with 11% of febrile neutropenia. In conclusion, the ACOD chemotherapy regimen seems safe and feasible in elderly patients. This schedule allowed a sufficient DI of chemotherapic agents with clinical results very similar to those recorded with the standard CHOP regimen in young adults.

Anti-apoptotic proteins Bcl-2 and Bcl-xL are overexpressed in 80% of non Hodgkin's lymphoma cells and are thought to play an important role in the resistance of lymphoma cells to current chemotherapeutic agents. Gossypol, an orally-active polyphenolic aldehyde derived from the cotton plant, has been known to have potential anti-neoplastic activity. Recently, gossypol was found to bind to the BH3 binding groove of Bcl-xL and with lesser affinity to Bcl-2. The present study was conducted to determine whether gossypol increases the sensitivity of non-Hodgkin's lymphoma cells to the actions of chemotherapeutic agents by potentiating treatment-induced apoptosis. The interactions observed between gossypol and chemotherapeutic drugs were analyzed using the median effect principle (CalcuSyn analysis). Our data showed that treatment of Ramos cells with gossypol not only induced cell arrest on the G(0)/G(1) phase, but also augmented apoptosis and growth inhibition induced by etoposide (VP-16), doxorubicin hydrochloride (ADM), vincristine (VCR), and paclitaxel (taxol). However, when gossypol was combined with cisplatin (DDP) an antagonistic effect was observed. Gossypol-induced cell cycle arrest was accompanied by decreased expression of cyclin D1 in Ramos cells. In addition, the peroxisome proliferator-activated receptor (PARP) pathway is, at least in part, involved in the gossypol-induced apoptosis when combined with VP-16. These data indicate that single-agent gossypol is effective in inhibiting growth of non-Hodgkin's lymphoma cells in vitro and combination studies with certain secondary chemotherapeutic agents further demonstrate it's synergistic cytotoxicity. These findings support future preclinical and clinical studies of gossypol in the treatment of non-Hodgkin's lymphoma.
