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.

Consolidation radiation after complete remission in Hodgkin's disease following six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy: is there a need?

PURPOSE: Combined modality treatment using multidrug chemotherapy (CTh) and radiotherapy (RT) is currently considered the standard of care in early stage Hodgkin's disease. Its role in advanced stages, however, continues to be debated. This study was aimed at evaluating the role of consolidation radiation in patients achieving a complete remission after six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy using event-free survival (EFS) and overall survival (OS) as primary end points. PATIENTS AND METHODS: Two hundred and fifty-one patients with Hodgkin's disease attending the lymphoma clinic at the Tata Memorial Hospital (Mumbai, India) from 1993 to 1996 received induction chemotherapy with six cycles of ABVD after initial staging evaluation. A total of 179 of 251 patients (71%) achieved a complete remission after six cycles of ABVD chemotherapy and constituted the randomized population. Patients were randomly assigned to receive either consolidation radiation or no further therapy. RESULTS: With a median follow-up of 63 months, the 8-year EFS and OS in the CTh-alone arm were 76% and 89%, respectively, as compared with 88% and 100% in the CTh+RT arm (P =.01; P =.002). Addition of RT improved EFS and OS in patients with age < 15 years (P =.02; P =.04), B symptoms (P =.03; P =.006), advanced stage (P =.03; P =.006), and bulky disease (P =.04; P =.19). CONCLUSION: Our study suggests that the addition of consolidation radiation helps improve the EFS and OS in patients achieving a complete remission after six cycles of ABVD chemotherapy, particularly in the younger age group and in patients with B symptoms and bulky and advanced disease.

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.

Use of a reduced-intensity conditioning regimen for allogeneic transplantation in patients with chronic myeloid leukemia.

Reduced-intensity conditioning that harnesses the potential of a graft-versus-tumor (GVT) effect has been proposed as an alternative to conventional myeloablative allogeneic stem cell transplantation. The primary aim is engraftment and this can be achieved with minimal immunosuppression. In this report, we describe the use of such regimens for CML in 17 patients who received human leukocyte antigen (HLA)-matched sibling allografts. Conditioning was with fludarabine, antithymocyte globulin (ATG) and busulfan for the first 11 patients, whereas fludarabine, busulfan and TBI were used for the remaining six patients. Engraftment was prompt in most of the cases. Complications and need for supportive therapy in the immediate post-transplant period were reduced drastically. Only two patients (both in the TBI group) died within the first 100 days. Acute graft-versus-host disease (GVHD) grade II-IV was seen in seven patients. Complications occurred later on. Chronic GVHD was observed in 11/17 patients. Lung infection and GVHD were the major killers. In surviving patients, after a median follow-up of 30 months (range 37-21 months), 6/17 (35.3%) are alive. Five are disease free and one patient is still in relapse even after a second donor lymphocyte infusion. Total treatment time and cost were more than with conventional transplants. We conclude that reduced-intensity transplantation still requires further refinement.

Pulmonary microsporidial infection in a patient with CML undergoing allogeneic marrow transplant.

Very few cases of human microsporidial infection have been reported. The advent of AIDS has changed this. There is increasing recognition that microsporidia are important opportunistic pathogens. However, the number of cases reported in the non-HIV population is small. We report here a case of microsporidial infection in a female patient with chronic myeloid leukemia undergoing allogeneic bone marrow transplantation. There was also an associated fungal infection. The diagnosis could be reached only after postmortem and was confirmed by electron micrography. We suggest that transplant patients are another group of patients who are susceptible to this group of opportunistic pathogens.

Activation of HHV-6 in lymphoproliferative disorders: a polymerase chain reaction-based study.

HHV-6 is a latent herpes virus persisting throughout the adult life of the infected host in an integrated form and is often activated in immunocompromised situations. Detection of HHV-6 DNA in the plasma of an individual indicates the presence of active viral replication in the host. Because lymphomas are known to be associated frequently with host immunosupression, we studied activation of HHV-6 in 98 patients diagnosed with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL). HHV-6 activation was documented in 34% of cases of non-Hodgkin's lymphoma and 39% of those of Hodgkin's disease; however, no correlation of activation status with pathological types of Hodgkin's disease and between copy numbers in peripheral blood mononuclear cell DNA and the corresponding plasma DNA was noticeable.

Development of Ph positive chronic myeloid leukemia in a patient with chronic lymphocytic leukemia treated with total body irradiation: a rare association.

Philadelphia (ph) chromosome positive chronic myeloid leukemia developed in a patient treated for chronic lymphocytic leukemia after treatment with total body irradiation. The role of radiation in the development of CML is discussed.

Urinary bladder cancer following cyclophosphamide therapy for Hodgkin's disease.

Urinary bladder cancers following prolonged cyclophosphamide therapy are being increasingly reported. We report a case of transitional cell carcinoma of the urinary bladder occurring 12 years after pulse intravenous therapy with cyclophosphamide for Hodgkin's disease. The mechanism of bladder carcinogenesis and the possible role of the uroprotector MESNA in preventing cyclophosphamide induced bladder cancer are discussed.

Primary Liver Lymphoma: A Case Report with Review of Literature.

Primary non-Hodgkin's lymphoma of the liver is exceedingly rare and until now only 53 cases have been recorded. Most extranodal non-Hodgkin's lymphomas are in the head and neck region and the gastrointestinal tract. We report a patient with primary non-Hodgkin's lymphoma of the liver and also review the relevant literature.

Survival of childhood acute lymphoblastic leukemia: results of therapy at Tata Memorial Hospital, Bombay, India.

The purpose of this study was to analyze the outcome of patients who completed therapy for acute lymphoblastic leukemia (ALL) and to study the role of an aggressive induction regimen in preventing post therapy relapses. Four hundred and twenty-two patients with ALL who completed therapy during the period 1975-1991 were followed. Two hundred and sixty patients received the aggressive MCP 841 protocol and 162 patients received various other less aggressive treatment regimens. Patients were followed with periodic examination and complete blood counts. The incidence of post therapy relapse was 27% in the less aggressive protocols and 15% in the MCP 841 protocol (p = 0.001). An higher percentage of relapses was seen in males (p = 0.05) and 89% relapses occurred within two years of stopping therapy. The relapse rate after 5 years of cessation of therapy was 0.59%. In conclusion, aggressive induction therapy is the most crucial factor in predicting relapses following cessation of therapy in ALL patients. However, relapses are unlikely to occur five years post therapy.

Gonadal function following ABVD therapy for Hodgkin's disease.

To assess the effect of combination chemotherapy with doxorubicin, bleomycin, viablastine, and decarbazine (ABVD) on gonadal function in patients treated for Hodgkin's disease, we assessed 38 male patients with Hodgkin's disease who were > 15 years of age and in complete remission for the development of secondary sexual characteristics, sexual habits, and fatherhood after treatment. Semen analysis and serum hormone level estimation of follicle-stimulating hormone (FSH), leutinising hormone (LH), and testosterone (T) were done in all cases. Twenty-six patients received ABVD therapy and 12 received a combination of ABVD with COPP or MOPP (cyclophosphamide or nitrogen mustard, vincristine, procarbazine, and prednisone). Radiation of the pelvic region was done in one case. Median time between completion of therapy and assessment of gonadal function was 34 months (range, 12-68 months). Secondary sexual characteristics developed normally in all patients. Azoospermia was seen in one patient from the ABVD group and 10 patients from the COPP/ABVD group (p < 0.001). Serum FSH levels were significantly higher in the COPP/ABVD group than in the ABVD group (23.5 versus 4.7 mlu/ml; p < 0.001) The levels were in the normal range in 23 patients from the ABVD group, as compared to four in the COPP/ABVD group (88.5% versus 33.3%; p < 0.001). Three patients treated with ABVD fathered children post-therapy. We conclude that ABVD is associated with relatively better preservation of gonadal function.

Limitations of the therapeutic regimens for myelodysplastic syndrome.

Thirty patients of myelodysplastic syndrome (MDS) were treated over a period of 2 yr using 3 different treatment regimens. Twelve patients received hydroxyurea, 4 were given low dose cytosine arabinoside and 14 others were treated with an aggressive acute myeloid leukaemia (AML) induction regimen. A low complete remission was obtained in the first 2 groups (17 and 25% respectively), whereas 9 (64%) patients attained complete remission with the AML induction regimen. Remission in the latter group was associated with prolonged and severe pancytopenia requiring intensive support. Patients in all the 3 groups had a short duration of remission culminating in death with progressive marrow failure or evolution to AML, indicating the limitations of the current treatment strategies for MDS and highlighting the need for exploring newer therapeutic approaches.

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)

Effect of hydroxyurea on foetal haemoglobin in myeloproliferative & myelodysplastic syndromes.

The effect of hydroxyurea on foetal haemoglobin (HbF) levels was evaluated in 36 patients of myeloproliferative and myelodysplastic disorders. In 17 (47.2%) patients, HbF levels increased from 1.40 +/- 1.17 to 3.03 +/- 1.97 per cent after 4 wk therapy with hydroxyurea. In the responders this increase was highly significant (P less than 0.001). The rise in the HbF levels after hydroxyurea therapy was significant in patients with chronic myeloid leukaemia but not in the other groups.

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.

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.

Cisplatin-based chemotherapy in advanced ovarian cancer: initial experience in an Indian set-up.

Forty patients of advanced ovarian carcinoma were treated with monthly cycles of cyclophosphamide, adriamycin and cisplatin. Debulking surgery was done in 29 cases. Clinical complete response was seen in 70 percent and an overall response in 85 percent of cases. The median follow-up was 30 months. The actuarial overall survival was 45 percent and the disease free survival was 35 percent at 3 years. The present protocol appears to have an important influence on initial control of disease but relapses continue to occur following the treatment. Cytoreductive surgery before or after three cycles of chemotherapy has a favourable influence on disease free survival (DFS). Prolonged follow up will be necessary to determine the overall influence on long term survival.

Primary pulmonary non-Hodgkin's lymphoma: a report of four cases.

Four cases of primary non-Hodgkin's lymphoma of the lung are described. Two cases had low and two intermediate grade lymphoma at the time of diagnosis. The patient who had disease for long duration and received pulmonary radiotherapy developed intractable chest infection and died six months after diagnosis; the three patients having short history of disease and treated with surgery and/or chemotherapy have been doing well for 4 to 77 months after the diagnosis. It is concluded that diagnosis of primary pulmonary lymphoma should be suspected in patients with nodular or interstitial lung disease and bronchoalveolar lavage with aspiration cytology should be done to make an early diagnosis.
