Highly elevated serum CA 125 in a lady with ascites and retroperitoneal mass--a diagnostic dilemma.

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.

Outcome of acute myeloid leukaemia in adults: a retrospective analysis.

BACKGROUND: There are little data from India on the management of acute myeloid leukaemia. With better understanding of the biology of the disease, and routine use of high-dose cytarabine as post-remission therapy with or without haematopoietic blood stem cell transplantation (HSCT), the results have improved in the past two decades. We analysed our results in a cohort of recently treated patients. METHODS: A total of 166 newly diagnosed patients with AML (excluding acute promyelocytic leukaemia), 15-60 years of age were treated with daunorubicin (60 mg/m2/day x3 days) or idarubicin (12 mg/m2/day x3 days) with cytarabine (100 mg/m2/day continuous i.v. infusion x7 days) induction chemotherapy. Post-remission therapy included 2 cycles of high-dose cytarabine (15-18 g/m2) followed by monthly cycles of outpatient maintenance chemotherapy x4 cycles, consisting of daunorubicin (45 mg/m2 i.v. x1 day and cytarabine 100 mg/ m2 s.c. twice daily x5 days). Six patients in remission received sibling donor allogeneic HSCT. RESULTS: Morphological complete remission was achieved in 69.9% of the patients. Resistant disease after induction chemotherapy was seen in 14.6% and early mortality occurred in 16%. Relapse-free survival and event-free survival at a median of 36 months was 34% and 22%, respectively. Relapse occurred in 43.9%. The median duration of remission was 12 months. CONCLUSIONS: Our results conform to the published literature from larger cooperative studies from the West. Currently available cytotoxic drugs are unlikely to improve the results any further.

Allogeneic blood stem cell transplantation in chronic myeloid leukaemia-chronic phase following conditioning with busulphan and cyclophosphamide: a follow up report.

BACKGROUND: Allogeneic bone marrow transplantation (BMT) or peripheral blood stem cell transplantation remains the only modality of treatment that can eradicate a leukaemia clone in the majority of patients with chronic myeloid leukaemia (CML). However, the advent of the targeted molecule imatinib mesylate (formerly STI-571) against the bcr-abl chimeric protein in the disease has brought the issue of managing newly diagnosed CML patients, especially those with available donors, to the crossroads. Although the curative potential of this agent remains unknown, it can produce complete cytogenetic response in > 60% of newly diagnosed patients. METHODS: From May 1991 to October 2002, a total of 55 Ph+ CML-chronic phase patients received oral busulphan 16 mg/kg and cyclophosphamide 120 mg/kg i.v. as a conditioning regimen. All patients received human leucocyte antigen (HLA)-identical sibling donor haematopoletic stem cells--bone marrow in 41 patients (74.5%) and peripheral blood stem cells in 14 (25.4%). Post-transplant prophylaxis for graft-versus-host disease included a short course of methotrexate (on days +1, +3, +6 and +11) and cyclosporin till day +180 in 38 patients (69.1%), while a combination of cyclosporin and methylprednisolone was used in the remaining 17 (29%). RESULTS: At a median follow up of 48 months (10-144 months), 26 patients (47.3%) are alive. Early mortality (100-day) occurred in 17 patients (30.9%). Acute graft-versus-host disease developed in 37 patients (67.3%), and was grade IV in 6 of them. Chronic graft-versus-host disease developed in 17 patients (30.9%). Relapse occurred in only 2 patients (3.6%) till date. The leukaemia-free survival is 64.3% in the peripheral stem cell group, whereas it is 41.5% in the bone marrow recipient group. CONCLUSION: Allogeneic BMT appears to result in eradication of CML and ensure disease-free survival in about half the patients. However, efforts should be made to prevent graft-versus-host disease and minimize early mortality.

Palliation of malignant colonic obstruction by self-expandable metal stent.

Advanced obstructive colorectal cancer is routinely treated by surgical colostomy. Self-expandable metal stents are a promising alternative. We report the use of an expandable metal stent to relieve colonic obstruction in an elderly lady with advanced colorectal malignancy.

Results of allogeneic bone marrow transplant in chronic myeloid leukaemia following conditioning with busulfan and cyclophosphamide.

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--results with alpha interferon therapy.

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.

Antilymphocyte globulin (ALG) or antithymocyte globulin (ATG) with methylprednisone and oxymethalone in aplastic anaemia.

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.

Low dose cytosine arabinoside in the treatment of myelodysplastic syndrome.

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.

Evaluating efficiency of bone marrow harvest and its manipulation--role of CD 34 positivity.

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.

Modified MACOP-B chemotherapy for intermediate and high grade non Hodgkins lymphomas.

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.

Myelodysplastic syndrome. A clinical and pathological analysis of 88 patients.

Eighty eight patients with myelodysplastic syndromes were studied to determine the clinical and pathological features and the prognosis. All the patients had anemia. Neutropenia was seen in 44% and thrombocytopenia in 78% patients. The subtypes included refractory anemia in six, refractory anemia with ringed sideroblasts in three, refractory anemia with excess blasts in 30, refractory anemia with excess blasts in transformation in 32 and chronic myelomonocytic anemia in 17 patients. Forty four patients who received chemotherapy were evaluable for response. Three of the 15 patients treated with hydroxyurea achieved partial remission. Eighteen patients were treated with low dose cytosine arabinoside and complete remission was achieved in five and partial response in six patients. Aggressive chemotherapy was given to 11 patients at the onset of the illness resulting in complete remission in six and partial response in two patients. Nineteen of the 88 patients transformed to acute myeloid leukemia. The crude survival of all the patients ranged from 15 days to 22.5 months. The mortality was due to hemorrhage in 15% and septicemia in 85%. Our data reveals ineffectiveness of the current therapy and emphasizes on the need to develop newer therapeutic approaches.

Primary lymphoreticular tumors of the orbit.

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.

Prognostic significance of myeloperoxidase containing blast cells in acute myelogenous leukaemia.

Fifty three newly diagnosed patients of de novo acute myelogenous leukaemia (AML) received treatment consisting of remission induction with daunorubicin 60 mg/m2 on day one and continuous infusion of cytosine arabinoside 200 mg/m2/day over 24 h from day one to 7. Thereafter patients in complete remission received consolidation chemotherapy with two identical courses. Complete remission (CR) could be achieved in 40 patients (75.5%). Seven patients (13.2%) died with complications during aplasia phase following remission induction therapy while six patients (11.3%) had resistant disease. Twenty seven patients (67.5%) developed relapse while eight patients (15.1%) continue to remain in complete remission ranging from 51 to 68 months (median 62.5). The projected event free survival and disease free survival at 60 months is 15 per cent (SE + 11.9%) and 21 per cent (+6%) respectively. Evaluation of the prognostic significance of pretherapy characteristics showed that infection at presentation and low number of myeloperoxidase (MPO) containing blasts affected the achievement of complete remission adversely on univariate analysis. Similarly age at diagnosis, of more than 45 yr, total leucocyte count of 50,000/cumm or more and low number of MPO containing blasts affected the remission duration (disease free survival) adversely on univariate analysis. On multivariate analysis, MPO positivity of blast cells, remained the only significant independent characteristic. High MPO positivity affected the remission duration favourably (P < 0.01). Patients with high MPO positivity also achieved CR with one induction cycle in 32 out of 40 instances while only 2 out of 5 patients with low MPO positivity, achieved CR with one chemotherapy cycle (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Primary lymphoma of breast--report of six cases and review of literature.

Six patients of primary lymphoma of breast are presented. All our patients were female with median age of 46 years. Combination chemotherapy was the mainstay of treatment in all the patients. Five patients achieved complete remission of which two relapsed, one had a distant relapse and the other was local. Patient with distant relapse expired after a follow-up of 224 months whereas the one with local recurrence was well controlled with radiotherapy only. The role of combination chemotherapy to decrease the distant relapse and thereby mortality is discussed.

Long term survival in a patient with multiple myeloma. A case report with review of literature.

A 37 year old man with symptomatic multiple myeloma diagnosed in April 1968 presented with generalised bony pains, extensive skeletal osteolytic lesions, monoclonal gammopathy and 90 percent atypical plasma cells in the marrow. He was given cyclophosphamide for six months with minimal response and then initiated on melphalan for one year. He was asymptomatic for 15 years thereafter and presented again in 1985 with a relapse of the disease. Over the next four years he was given various combinations of chemotherapy including cyclophosphamide, vincristine, melphalan and carmustine. He responded well on two more occasions only to relapse again. Recently, he has developed a symptomatic relapse with 36 percent plasma cells. This case report highlights the fact that there is a subset of patients with myeloma who survive beyond ten years, but remain symptomatic and respond slowly to chemotherapy.

Alpha-interferon in hairy cell leukemia: an initial Indian experience.

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.

Non-Hodgkin's lymphoma of prostate: a rare site of primary extranodal presentation (a report of two cases).
