Childhood non-Hodgkin's lymphoma in Egypt: preliminary results of treatment with a new ifosfamide-containing regimen.

Pediatric non-Hodgkin's lymphoma (NHL) constitutes 16% of pediatric malignancies reported to the National Cancer Institute (NCI) in Cairo. Since July 1985, we have treated 39 previously untreated pediatric NHL cases younger than 16 years of age (mean, 7.6 years) with a new protocol consisting of alternating cycles: regimen A comprised cyclophosphamide, high-dose ara-C, Adriamycin and vincristine; regimen B consisted of ifosfamide, methotrexate and VP16, with intrathecal methotrexate. Diagnoses included 20 abdominal masses, 16 peripheral lymphadenopathies and 6 bony lesions. Histopathology according to the working formulation revealed 21 cases of small non-cleaved lymphoma, 6 lymphoblastic, 5 large-cell and 7 unclassified diffuse lymphomas. Responses were complete in 31 cases (82%) and partial in 4 cases (10%), and no response was obtained in 4 cases (8%). Overall survival was 82% in limited disease and 60% in extensive disease at 28+ months. This short-term ifosfamide-containing regimen proved its efficacy, with results matching those of other regimens used in the United States and Europe.

The impact of schistosomiasis on the pathology of bladder carcinoma.

In a series of 1095 Egyptian patients with carcinoma of the bladder treated by radical cystectomy, 902 cases (82.4%) contained schistosome eggs in the specimens, and 193 (17.6%) were egg-negative. The different tumor parameters were compared in these subgroups to explore any differences that could be related to schistosomal infestation. In egg-positive cases, the tumor developed at a younger age (46.7 years) than in egg-negative cases (53.2 years). Squamous cell carcinoma, commonly of low grade, predominated in the egg-positive group. No difference was observed in the frequency of tumor stages or lymph node metastases between the two subgroups. The limited tendency to distant spread in schistosomal bladder cancer, despite its advanced local stage, is accounted for by the high frequency of low grade tumors rather than the limiting effect of local schistosomal tissue reactions.

Pediatric non-Hodgkin's lymphoma abdominal presentations: a comparative study between two treatment regimens at the National Cancer Institute Cairo.

Abdominal presentations of pediatric NHL are rarely amenable to complete surgical resection. Chemotherapy is the hallmark of treatment for pediatric NHL. Treatment of various types of this disease including intra-abdominal NHL in children with various protocols have not exceeded 54 per cent two-year disease-free survival. We have attempted to study and compare the effects of two treatment regimen upon two groups of previously untreated children up to the age of 16 years who presented to the Pediatric Oncology Unit at the NCI. The first group included 18 children who presented between 1983 and 1985 and were treated by a modified St Jude regimen: while the second group of patients was comprised of 19 children who presented between 1985 and 1987 and were treated by a multi-national protocol: the MCP 842. The two groups will be compared with respect to various patient characteristics, response to therapy and their two-year disease-free survival as well as overall survival.

Prolonged disease-free survival in pediatric non-Hodgkin's lymphoma using ifosfamide-containing combination chemotherapy.

Pediatric non-Hodgkin's lymphoma (NHL) constitutes 16 per cent of pediatric malignancies reported to the National Cancer Institute (NCI) in Cairo. The adopted treatment for these cases was, from 1982 to July 1985, a modified St Jude's regimen consisting of: vincristine, cyclophosphamide, adriamycin, prednisone and intrathecal methotrexate for the first 6 weeks for induction, followed by cranial irradiation for cranial prophylaxis. Patients in remission received maintenance therapy for 18 months. Of 32 patients complete remission (CR) was achieved in 24 patients (75 per cent); partial remission (PR) in one patient (3 per cent); five patients showed no response (15 per cent) while two patients died during the induction phase. At 60+ months follow-up, 60 per cent of cases are still alive, disease-free, and overall survival is 66 per cent. A new protocol was adopted in 1985, consisting of alternating cycles: A and B, for 4-8 cycles. Cycle A: cyclophosphamide, high dose ara-C, adriamycin, and vincristine. Cycle B: ifosfamide, methotrexate, VP 16, with intrathecal methotrexate. The response in 39 cases is: CR in 31 cases (82 per cent); PR in four cases (10 per cent); no response in three cases (8 per cent). At 60+ months, the disease-free survival is 60 per cent, and overall survival 80 per cent. This new protocol has the advantage of: short duration of therapy and so better patient compliance, no maintenance therapy or cranial irradiation with its sequelae in the future. Moreover, it has a better overall survival.
