Background: Cancer antigen 125 (CA 125), a widely used tumor marker for monitoring epithelial ovarian cancer, is also found to be raised in non-gynecological tumors and non malignant disease involving peritoneum. We report a case of non-Hodgkin's lymphoma who presented with peritoneal and pleural effusions with a very high level of serum CA 125., Case: Fifty four years female presented with gross ascitis, bilateral moderate pleural effusions, right retroperitoneal mass and a very high serum CA 125 level (4462.60 u/ml). She was initially evaluated to rule out ovarian malignancy but her biopsy from retroperitoneal mass came out to be diffuse large B cell non-Hodgkin's lymphoma., Conclusion: In a female patient with ascitis with high serum CA 125 level, a differential diagnosis of lymphoma should not be overlooked unless cytology comes positive for epithelial carcinoma cells.

Objective: To study the outcome of oral busulfan and intravenous cyclophosphamide (BuCY 2 regimen) followed by allogeneic bone marrow transplant (BMT) in a cohort of patients with Philadelphia chromosome (Ph+) chronic myeloid leukaemia (CML) in a single centre., Methods: From 1991 to March 1998, a total of 27 consecutive Ph+ CML patients received busulfan 4 mg/kg/day over 4 days and cyclophosphamide 60 mg/kg/day over 2 days followed by infusion of HLA-identical sibling haematopoietic stem cells. All except one (who received peripheral blood stem cells) were given donor bone marrow cells. Post-transplant graft versus host disease (GVHD) prophylaxis included a short course of methotrexate (on days +1, +3, +6 and +11) and cyclosporine till day +180., Results: With a median follow-up of 30.5 months (1-55+ months), 14 patients (52%) are alive free from relapse. Early mortality was relatively high with 10 patients (37%) dying within first 100 days post-transplant. Acute GVHD developed in 14 patients (52%) inspite of GVHD prophylaxis with methotrexate and cyclosporine; six had grade I/II and eight grade III/IV. Chronic GVHD developed in five of 15 patients who lived beyond 70 days., Conclusion: Allogeneic BMT appears to result in eradication of CML and ensure disease free survival in about half of the young patients. However, efforts should be on to minimise early mortality.

Hairy cell leukemia (HCL) is a rare lymphoproliferative disorder. Although now multiple treatment options are being available, the optimal treatment of this disease still remains debatable. Inspite of the advent of newer purine analogues, in India recombinant interferon is the only freely available first line treatment. We report our experience of long term remissions in HCL with interferon alpha 2a. Of a total of 35 cases of HCL we were able to treat 19 cases with interferon. Of 18 evaluable cases an overall response of 88.9% was achieved. With a median follow up of 31 months a disease free survival was 83%. Thus with a dose of 3 million units s.c. daily for 6 months at least, we feel that a reasonably good long term remission can be obtained. The cost of the treatment however, is still a deterrent.

From 1986 to 1994 we treated 26 patients of aplastic anaemia between 6 to 61 years age group with ATG/ALG, Methylprednisone and Oxymethalone. Five had very severe aplastic anaemia, 16 had severe and 5 nonsevere disease. Disease was associated with hepatitis in 5 patients and with pregnancy and drug use in 2 patients each. In others no cause could be ascertained. A total of 31 courses of treatment were given (range 1-3 courses per patient). Nine patients had complete response (34.62%) and 3 had partial response (11.54%) with an overall response rate of 46.16%. Four patients died within 2 months of starting the treatment. The median follow up was 24 months (range 6-102 months) with an overall survival probality of 45% at 2 yr. At the time of evaluation 12 patients have died, 9 are alive disease-free and 5 are alive with disease. The side effects associated with therapy were tolerable and did not require cessation of therapy in any patient. We conclude that ATG/ALG with Methylprednisone and Oxymethalone is beneficial to significant number of patients with aplastic anaemia.

Twenty eight patients of myelodysplastic syndrome (MDS) were treated with low dose cytosine arabinoside to study the effect of this treatment modality. All patients presented with a hemoglobin of less than 12 Gm/dl, 4 (15%) had neutropenia with an absolute neutrophil count of less than 500 x 10(6)/L and 18 (65%) had thrombocytopenia of less than 100 x 10(9)/L. The subtypes according to the bone marrow evaluation included 14 patients of refractory anemia with excess blasts (RAEB), 10 refractory anemia with excess blasts in transformation (RAEB-T), and 4 chronic myelomonocytic leukemia (CMML). Five patients (18%) achieved complete hematological response, 10 (36%) had a partial response and 9 (33%) patients had no response. Four patients died early during treatment due to tumor lysis (1 CMML) and hemorrhage (3 RAEB). Seven patients progressed to acute myeloid leukemia (AML) while on therapy and three progressed to AML after completion of therapy. Five patients died of hemorrhage and 3 of septicaemia after achieving an objective response. The mean duration of follow up in these patient was 8 months (range 1 month-3 years). Only 3 patients of RAEB have survived for greater than 2 years. Our data reveals the short term benefit of this mode of therapy and emphasizes the need to develop newer therapeutic approaches.

We evaluated harvested marrow cells for total nucleated cells (27.49 x 10(9)), absolute 'lymphocyte' count (6.29 x 10(9)) and CD 34 positive cells (3.57 x 10(9)). The same parameters were studied after in vitro manipulation to remove RBCs and plasma. Reinfused WBCs contained 12.87 x 10(9) nucleated cells, 4.25 x 10(9) absolute 'lymphocyutes' and 3.34 x 10(9) CD 34 positive cells. The corresponding figures for loss during in vitro manipulation (tubing, RBCs and plasma) are 14.62 (53.18%), 2.04 (32.43%) and 0.23 x 10(9) (6.44%) cells respectively. Therefore CD 34 positivity may be a better indicator of total yield, loss during manipulation and reinfusion of hemopoietic progenitor cells in bone marrow transplantation.

Combination chemotherapy consisting of methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisolone and bleomycin (MACOP-B) has been extensively used for the treatment of Non Hodgkins Lymphoma. However, different results have been reported. The aim of this study was to assess the feasibility of administration of this regimen on an out patient basis and to confirm the efficacy of MACOP-B. 51 patients with intermediate--and high--grade lymphoma were treated with this regimen in a single institute study. Numerous clinical features predictive of response and disease free survival were analysed. The Median age was 48 years (range 14-77). Diffuse large cell lymphoma was seen in 65%, diffuse small cleaved in 10% and diffuse mixed in 15%. Eight patients (15%) had Stage I disease, 18 (35%) Stage II, 12 (23%) Stage III and 13 (25%) Stage IV. Complete remission was achieved in 65% of the patients. With a median follow up of 18 months, 40% of the patients are alive at 40 months. Sixty percent of the complete responders are disease free at 40 months. Response rates did not differ significantly for age, sex, stage, histology, bone marrow involvement and extranodal disease. However patients with absence of B' symptoms, non bulky disease at presentation and diffuse large cell histology had a higher percentage of complete remission. Hematological toxicity occurred in 90% and was grade IV in 14% patients. Three patients died of sepsis. Severe mucositis occurred in 40% of the patients. In conclusion, while it is possible to give aggressive chemotherapy at the out patient basis in India we failed to confirm the high response rates as originally reported.

Primary orbital lymphomas are rare. We report nine such cases (4 with DWDL, 3 with DPDL, 1 with DHL and 1 unclassifiable lymphoma). All patients achieved clinical complete remission (CR). Of those who completed treatment more than a year ago, three continue to be in CR at 17, 24 & 25 months and two are lost to follow up.

In the last decade, 14 patients were diagnosed as having hairy cell leukemia (HCL) at our hospital; five of these were treated with the biological response modifier, recombinant alpha-interferon (IFN), as their initial treatment. Four of these cases showed a complete remission of the disease while one had a good partial response after a few months of therapy. One case is in unmaintained remission while one has relapsed with a just palpable spleen on stopping the drug; two are still on intermittent IFN therapy while one has been lost to follow up. Fever and skin rash were the most common side effects observed but did not warrant reduction of dose or stoppage of treatment. We conclude that IFN is highly effective and well tolerated as initial treatment of HCL in a country like India. Splenectomy will continue to be the first line therapy in the majority of cases but, in certain selected situations, IFN can be an extremely useful alternative.

Aggressive chemotherapy regimens and supportive measures in haemato-oncology patients demand reliable venous access. Experience with this method in India has been limited. During a period of six months, we have used 42 subclavian indwelling catheters and 31 cubital Cavafix long lines. The mean age of patients in the two groups was 32 years and 7 years respectively. Subclavian catheters had a median duration of catheter placement of 46 days (range 4-145) and total 1494 catheter days, while cubital longlines yielded a median duration of insertion of 14 days (range 4-27) and total 508 catheter days. Catheter related complications were infection in 25% of patients, thrombophlebitis in 22%, blockade in 12% and misplacement in 17% in both groups taken together. The patients and families were extremely satisfied with the devices. Our experience supports further use of durable venous access in cancer patients. Implanted central venous catheters should be preferred whenever feasible.

Between March 1983 and December 1985, six patients with haematological disorders (four acute nonlymphocytic leukaemias, one chronic phase chronic myeloid leukaemia and one severe aplastic anaemia have undergone allogeneic bone marrow transplantation. Four of the 6 patients are alive and free from disease between 33+ and 55+ months; two patients died due to grade IV acute graft versus host disease (GVHD).

A preliminary experience in the use of central venous catheters, including Hickman (15), subclavian jugular (Desseret) (50) and Secalon Hydrocath (3), in cancer chemotherapy is presented. There were no technical complications and no mortality attributable to catheterisation. Infections formed the major complication in Hickman (30%) and subclavian jugular (Desseret) (36%) catheters, while the use of Secalon Hydrocath was event-free. The commonest organism isolated was P aeruginosa (60%), followed by staphylococci (30%). Prolonged venous access was achieved with minimum morbidity. It is concluded that central venous catheters are safe and convenient both for the patient and the treating team, and should be used in all patients undergoing protracted chemotherapy and supportive care.

Thrombocytopenia is a rare side effect of amphotericin B. Two patients with acute leukaemia in remission who developed severe thrombocytopenia during amphotericin B therapy are reported. Thrombocytopenia recovered after the withdrawal of the drug in one patient and after reducing the dose in the other patient.

Fifty patients of multiple myeloma have been studied. Seventy eight per cent of the patients were in the 5th, 6th and 7th decades of life. Commonest presenting feature was bone pains (76%). 8%, 20% belonged to stage I, II and III respectively. Skull (58%), ribs (52%) and pelvis (24%) were most commonly involved. Immunoelectrophoresis revealed IgG type of myeloma in 76% and IgA type in 10% cases. Bence-Jones proteinuria was seen in 60% of patients; Kappa specificity was commoner than lambda. Overall survival at 30 months was 50%. The survival was adversely influenced by advanced stage, higher plasma cell count in the bone marrow, low haemoglobin and high serum creatinine values.

Four patients with Hodgkin's disease developed thrombocytopaenic purpura during remission phase. The interval at which it occurred following chemotherapy ranged from a period of 4 months to 4 years. Detailed investigations failed to reveal recurrence of Hodgkin's disease. All patients responded well to steroid therapy. In the median duration of one year follow-up Hodgkin's disease remained under control. Thus, the occurrence of thombocytopaenic purpura in patients treated for Hodgkin's lymphoma need not imply recurrence or active Hodgkin's disease.
