This is an analysis of the long-term follow-up data of 99 patients receiving HOAP-Bleo, IMVP-16 and PAC as salvage chemotherapy for refractory or relapsed intermediate or high grade non-Hodgkin's lymphomas. Most of the patients received HOAP-Bleo or PAC following failure of initial chemotherapy and IMVP-16 was used mainly for HOAP-Bleo failures. The longest follow-up time of the surviving patients was 108 months. Twenty-two and 29 per cent of the patients survived beyond 2 years following HOAP-Bleo and PAC respectively. The treatment outcome following IMVP-16 was worst with a 2-year survival of only 5 per cent, as it was used mainly following HOAP-Bleo failures. Although the prognosis of these refractory or relapsed cases are poor, salvage treatment is still worthwhile as a small proportion of these patients may have long-lasting remissions and occasional patients may be cured. Newer approaches such as autologous bone marrow transplantation should be compared with current salvage chemotherapy regimens.

A nation-wide clinical trial on a new antineoplastic drug, carboplatin(CP) supplied by Qilu Pharmaceutical Company, was carried out during the period of January to September 1989. Two hundred and forty-three patients with various malignant tumors were treated by CP as a single agent, 167-436 mg/m2 by intravenous infusion, repeated every 4 weeks, and 2-4 cycles as a course. The response rate was 75% (6/8) in testicular cancer, 56% (9/16) in ovarian cancer, 63% (15/24) in head and neck cancer, 37% (15/41) in small cell lung cancer and 60% (25/42) in non-Hodgkin's lymphomas. Randomized study of combination chemotherapy containing CP or cisplatin (DDP) was also conducted. The results showed that in small cell lung cancer, 73% (30/41) of the the patients responded to CE (CP + VP - 16) and 67% (24/36) responded to PE (DDP + VP - 16) and in ovarian cancer, the response rate was 60% (6/10) to CAC (CP + adriamycin + cyclophosphamide) and 36% (4/11) to PAC (DDP + adriamycin + cyclophosphamide) regimen. In addition, gastrointestinal reaction and renal toxicity were less severe in regimens containing CP than in regimens containing DDP. However, CP had more marked myelosuppressive effect.

The paper is concerned with the results of 13-year experience of combined therapy of Hodgkin's disease. The following therapeutic methods were employed: staging splenectomy, polychemotherapy (COPP, MOPP, ABVP and alternation of COPP and MOPP, COPP and CHOPP, COPP and DPP) and total irradiation of the lymph nodes. Altogether 328 patients with stage I-IV of disease were followed-up. Complete remissions were observed in 68.8%. A 10-year recurrence-free period was noted in 60% of the patients (stage I--100%, stage II--85%, stage III--68.6%, stage IV--48%).

Invasive thymoma recently has been shown to be sensitive to combination chemotherapy and in some cases to be relatively indolent. Two cases of extensive thymoma which responded to primary treatment with a combination of a platinum compound (carboplatin or cisplatin), doxorubicin (Adriamycin), and cyclophosphamide (or PAC) are described. Tumor progression occurred 14 (case 1) and 60 months (case 2) after completion of initial PAC therapy and was treated with the same regimen resulting in a second remission, which lasted 6 months in case 1 and is continuing at 8 months in case 2. Similar reports of secondary responses using the same chemotherapy have been described in breast, lung, and ovarian cancers, as well as in Hodgkin's lymphomas. Our observations suggest that retreatment with the same platinum-based regimen should be considered in patients who have progressive thymomas following a previous chemotherapeutic response and a disease-free interval of greater than 12 months.

Rearrangement of the BCL2 gene is an important parameter for the differential diagnosis of non-Hodgkin lymphomas. Although a relatively large proportion of breakpoints is clustered, many are missed by standard PCR. A FISH assay is therefore desired. Up to now, a lack of probes flanking the BCL2 gene has limited the possibilities for a FISH assay to an approach based on colocalization of probes for BCL2 and the immunoglobulin heavy chain (IGH) locus. Intrinsically high rates of false positive nuclei and high interobserver variability make such assays unsuitable for use on lymphoma tissue samples, where tumor cells often form only a minority of the cell population. Using YAC end cloning techniques and screening of a PAC library, we have isolated PAC clones flanking the BCL2 gene. Using these PACs, and several cosmid clones in the second BCL2 intron, we developed a segregation-based interphase FISH assay with two probe combinations enabling separate detection of 5' and 3' (mbr/mcr) breakpoints. The assay was applied to a series of 40 follicular lymphomas. To evaluate the results, the same lymphomas were analyzed by DNA fiber FISH with a 600-kb set of BCL2 DNA clones labeled in alternating colors in combination with a color barcode covering the IGH locus. This approach allowed precise mapping of BCL2 breakpoints, and simultaneously showed juxtaposition of IGH genes to BCL2. Comparison of the results of interphase and fiber FISH showed complete correlation. Five cases were negative with both FISH techniques as well as with Southern blotting. Interestingly, all of these 5 cases lacked BCL2 overexpression as determined by immunohistochemistry, against 3 of 35 rearrangement-positive follicular lymphomas. Furthermore, absence of t(14;18) seemed to be correlated with a higher histologic grade (grades 2 and 3 according to Berard). These data indicate that the segregation-based interphase FISH assay detects 100% of BCL2 rearrangements. Because interpretation of the results is straightforward and requires no extensive experience, this assay may be the best available diagnostic test for BCL2 rearrangement.

Using histochemical methods, we studied distribution of dipeptidylaminopeptidase-IV (DPP-IV) in tumor cells of 16 patients with non-Hodgkin's malignant lymphomas (NHL) including B-cell NHL (10 cases), pleomorphic T-cell lymphoma (1 case), CD30+ anaplastic large cell lymphoma (ALCL) of T-cell (1 case) and ALCL of null-cell type (4 cases) and of 13 patients with Hodgkin's disease (HD). The results indicate that tumour cells of pleomorphic T-cell NHL and ALCL of T- and null-cell type showed DPP-IV activity. In contrast, no DPP-IV activity was seen in the tumor cells of B-cell NHL (lymphocytic, centroblastic/centrocytic, centroblastic, immunoblastic), in Berezovsky-Reed-Sternberg and Hodgkin's cells of different HD variants. These results demonstrate that difference in DPP-IV activity between tumor cells of ALCL and HD may be diagnostically important for separation of ALCL from HD and moreover may be used in verification of the borderline between HD-like ALCL and ALCL-like HD. It is possible that DPP-IV activity contributes to pathogenesis of ALCL and may determine clinical behaviour of this NHL being involved in autocrine and paracrine regulation of tumor cell growth of ALCL.

The translocation t(11;18)(q21;q21), which is the most frequent chromosomal aberration in extranodal marginal zone B cell lymphomas of MALT-type, was characterised in a series of 34 biopsies, including 18 gastric non-Hodgkin's lymphomas (NHL) of MALT-type, six MALT-type NHL of extragastral origin and 10 extranodal large B cell lymphomas (LBL). Based on fluorescence in situ hybridisation, STS-PCR analysis and screening of genomic PAC libraries, a physical map of contiguous DNA probes on chromosome 11 was constructed containing the anti-apoptotic genes API2 and API1 adjacent to the translocation breakpoint. RACE-PCR experiments revealed MALT1 the chromosome 18-derived fusion partner of API2, which has also been reported recently by other groups. RT-PCR analysis and DNA sequencing demonstrated the expression of an API2-MALT1 fusion transcript in 18/24 gastral and extragastral MALT-type lymphomas. In none of 10 LBLs was a translocation specific RT-PCR product detected. Five variants of the fusion transcript were identified and in all instances the open reading frame of the fused portion of the MALT1 gene was maintained. The molecular analysis of these variants allowed the design of optimised assays for the diagnosis of the API2-MALT1 gene rearrangement.

In contrast to other subtypes of lymphoproliferative malignancies, the genetic mechanisms underlying the pathogenesis of hairy cell leukemia (HCL) are unknown. We studied densely infiltrated splenic tissue of 14 cases of HCL for the presence of chromosomal gains and losses by comparative genomic hybridization (CGH). Chromosomal imbalances were detected in only four of the 14 cases. Chromosomal gains involved the regions 5q13-q31 (two cases) and 1p32-p36.2 (one case). A loss of the region 11q14-q22 was found in one additional patient. The imbalances affecting the regions 5q and 11q were confirmed by interphase fluorescence in situ hybridization (FISH) using PAC clone 144G9 (5q31) and YAC clones 755B11 (11q22.3-q23.1) and 801E11 (11q22.3-q23.1 spanning the ATM gene) and occurred in 61% to 75% of analyzed nuclei. The latter DNA probes and probes hybridizing to chromosomal regions, which are frequently deleted in other subtypes of non-Hodgkin lymphomas (NHL), namely 9p21/ P16(INK4A), 13q14/D13S25, and 17p13/P53 were subsequently applied to all 14 cases of HCL, but no additional abnormalities were found. We conclude that overrepresentation of chromosome 5 represents a recurrent aberration in HCL and that the commonly overrepresented region resides in 5q13-q31. Chromosomal imbalances including deletions of the tumor suppressor gene loci 9p21/P16(INK4A), 13q14/D13S25, and 17p13/P53 rarely occur in HCL in contrast to some other subtypes of B-cell NHL. The pathogenetic role of 11q/ATM alterations in HCL remains to be determined.

We have performed a systematic review of all new serum and urinary paraproteins detected over a six year period in an immunodiagnostic laboratory serving a population of 400,000 people. Clinical diagnoses and associated laboratory features were ascertained from a computerized laboratory database or from clinical notes. Over the period of study, serum or urine paraproteins were detected in 613 new patients. These consisted of 568 patients with serum paraproteins and 45 patients with urinary monoclonal free light chain (in the absence of a serum paraprotein). These paraproteins occurred more commonly in males and the frequency increased with age. Approximately 30% of the serum paraproteins and 60% of urinary monoclonal free light chain were associated with B cell lymphoproliferative disorders (multiple myeloma, plasmacytoma, Waldenstrom's macroglobulinemia, non-Hodgkins lymphoma, chronic lymphocytic leukemia, etc) with the remainder being labeled as monoclonal gammopathies of uncertain significance (MGUS). At clinical presentation, patients with lymphoproliferative disorders tended to have higher levels of paraprotein, B2 microglobulin, the presence of free urinary light chain and demonstrated molecular size heterogeneity of the paraprotein but there was considerable overlap. A good correlation was noted between paraprotein concentration and viscosity in most patients. In conclusion paraproteins were most frequently encountered in the context of a gammopathy of uncertain significance. Features which suggested lymphoproliferative disorders included higher levels of serum paraprotein (> 15 g/l), elevated levels of B2-microglobulin and the presence of urinary free high chain. However, as much overlap was seen with patients with MGUS, regular monitoring of paraprotein level is considered mandatory in the management of these patients.

The incidences of childhood cancers in Thailand between 1995 and 1997 were determined from cancer registrations collected at five locations around the kingdom and compared with similar analyses performed at cancer registries in Asia, Europe and the USA. The incidence in Thailand was found to be lower than in some Asian and Western countries. Between 1988-1994 and 1995-1997, the incidence of childhood cancer rose 32.5%. As elsewhere in the world, leukemias, brain tumors and lymphomas comprised two-thirds of all childhood cancers. The age-peak for incidence was between 2 and 5 years, particularly for acute lymphoblastic leukemia. Carcinomas were rare. Several features of the cancer pattern correspond to other Asian populations, in particular the low incidence of Hodgkin s disease, Wilms tumor and Ewing s sarcoma. Neuroblastoma was more common than in neighboring Southeast Asian countries.
