A 77-year-old male presented at our Department of Urology in August 1990 with a gradually enlarging swelling in the right scrotum. On August 21, right high orchietomy was performed. This was diagnosed histologically as non-Hodgkin's lymphoma (diffuse large cell type), and the patient was transferred to our department on September 11 for further examination and treatment. As enlargement of the lymph nodes around the abdominal aorta was evident, it was diagnosed as stage IIA according to the Ann Arbor Classification. Beginning on September 21, three courses of COP-BLAM therapy (CPM, VCR, PDN, BLM, ADR, PCZ) were administered (the third course started on November 8) to achieve complete remission. Hepatic dysfunction appeared, however, from November 16, and by November 19, GOT and GPT increased to 6700 and 2120, respectively, with aggravation of jaundice. PDN therapy was instituted, and GOT and GPT improved gradually, but jaundice did not improve. On December 22, laparoscopy was performed, and liver biopsy produced histologic findings of drug-induced hepatitis. Further, lymphoblastic response was positive for CPM. Hepatic failure occurred on December 29, and plasma exchange was performed, but it failed to improve the condition, and the patient died on January 15. We described a case of non-Hodgkin's lymphoma complicated by hepatic dysfunction, probably induced by CPM, in an elderly patient who died to hepatic failure.

Recent advances in adjuvant chemotherapy for malignant bone tumor have been improving the survival rate and making limb-salvage surgery a reliable technique. Ewing's sarcoma is treated by multiple agent chemotherapy. We treat Ewing's sarcoma by Rosen's T-11 protocol (CYT.ADM.MTX.VCR.ACT-D.BLM). This protocol is very effective, but results are poorer than for osteosarcoma. Newly developed protocols such as EICESS (European Intergroup Cooperative Ewing's Sarcoma Study)-92, including new drugs, should be investigated. The results with malignant fibrous histiocytoma are comparable to those for osteosarcoma. We have performed an original chemotherapy protocol, called "K-1 protocol." Patients were treated with three courses of intraarterial infusion of cisplatin (120 mg/m2) and caffeine (1.0-1.5 mg/m2/day for three days continuously) at two-week intervals. If the effect was insufficient, ADM (30 mg/m2/day for two days continuously) is added to this protocol. We treat malignant lymphoma in collaboration with a hematologist and radiologist. The 5-year survival rate of non-Hodgkin's lymphoma in our series was 56% in clinical stage III and 34% in clinical stage IV. We are trying third-generation chemotherapy to improve the survival rate.

An 87-year-old woman, who had been suffering from hypothyroidism and had been treated as an outpatient at our department since 1982, noticed left cervical swelling toward the end of November 1992. Because ultrasonic examination revealed a mass in her thyroid gland, she was admitted for a closer examination and additional treatment. Biopsy of thyroid gland revealed non-Hodgkin's lymphoma (NHL; the diffuse small cell type, B-cell origin). A part from the swelling of thyroid gland and the left cervical lymph node, performance of various examinations did not detected any other NHL lesions. Therefore, it was classified as stage II NHL according to the Ann Arbor classification. Laboratory data on admission were as follows; WBC 4,400/microliters, Hb 13.6 g/dl, platelet count 10.1 x 10(4)/microliters, GOT 51 IU/l, GPT 31 IU/l, TSH 1.17, free-T4 1.03, free-T3 2.04, and microsome test 1,600 x. Those data indicated marked hypothyroidism. In addition, stage IIa and IIc gastric cancers were detected by the examination with gastric endoscopy performed for stage classification. Both were adenocarcinomas. Because polyps were found in her sigmoid colon with colonoscopy, polypectomy was performed. The polyps were diagnose histologically as moderately differentiated adenocarcinoma. On July 20, COP-BLAM therapy was started (CPM 600 mg div, VCR 1.2 mg iv, ADR 30 mg iv on day 1, PDN 40 mg p.o and PCZ 100 mg p.o. on days 1-10, BLM 7.5 mg div on day 14). Subsequently, the left cervical lymph node swelling disappeared, and shrinkage of the mass in the thyroid gland was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Germ-line mutations (present in all cells) in genes that are crucial for the cell cycle cause cancer only in specific cell lines (e.g. mismatch repair genes in the colon; BRCA1-2 in breast and ovary; other cancers in Bloom syndrome, neurofibromatosis and xeroderma pigmentosum). The mutation rate of genes other than mismatch repair or p53 is the same in colon cancer and in normal cells, indicating that a 'mutator phenotype', increasing the rate of mutations in many genes, is not an essential feature of sporadic cancers; conversely, fusion genes, TEL-AML1/AML1-ETO, typical of leukemia, are 100 times more frequent at birth than in overt leukemia in children, indicating that further selective events are needed to cause malignancy. The devastating impairment of immunity, as in AIDS patients, does not cause cancer other than Kaposi's sarcoma and non-Hodgkin's lymphoma, although immunological control is considered to be an essential mechanism in preventing the spread of cancer cells. These observations suggest that cell-specific additional events are needed to explain carcinogenesis. Carcinogenesis has been traditionally interpreted as the sequence of initiation (mutation) and promotion (clone expansion), with an interesting similarity with the neo-Darwinian theory of evolution, based on a first stage of genetic change (including recombination) and a second stage of selection. I propose that carcinogenesis consists in two general phases (not necessarily stages), i.e. genetic change followed by clone expansion (selective advantage). As in neo-Darwinian theory selection is chiefly represented by the elimination of the less fit, the selection of mutated cells would mainly consist in resistance to apoptosis or other types of 'bottlenecks' that hamper a cell's survival; an example of such a bottleneck is the autoimmunity that induces paroxysmal nocturnal hemoglobinuria in individuals with PIG-A mutations. Cancer rates show great variation in different countries around the world, a variation only marginally explained by genetic differences. More interestingly, migrants change their risk of cancer by adapting to that of the population into which they move: as these changes are not likely to be entirely due to mutagens in the environment, we have to invoke selective pressure over mutated cells to explain them. My theory is that mutated cells adapt to environmental 'niches' better than normal cells, in a 'gene-environment interaction' that involves the history of the genetic changes the cell has undergone and the kind of environment in which it happens to live.

Treatment of the malignant neoplasms which develop in patients with chromosome fragile syndrome, such as Bloom's syndrome (BS), requires extremely careful planning of the chemotherapy regime because of the excessive chemosensitivity of patients with such syndromes. Two siblings with BS developed B cell-type non-Hodgkin's lymphoma in the third decade of their lives. In both cases a 3-bp homozygous deletion of the BLM gene was detected. Since the lymphoma of the older brother was nasopharyngeal in origin, he was administrated radiation therapy as the primary treatment. However, hepatic metastasis was detected and this was the cause of his death. A 9-bp deletion in exon 7 of the p53 gene was detected in the metastatic lymphoma. His younger sister developed a lymphoma of abdominal lymph node in origin. She received a half dose of the drugs used in the acute lymphoblastic leukemia treatment without radiation, and twenty months after the diagnosis of her lymphoma she continues to be in complete remission and free of treatment complications. The p53 gene mutation was not detected in her lymphoma. These results suggest that radiation therapy and the radiation dose for the treatment for lymphoma in patients with BS should be carefully considered.
