One thousand and twenty four patients with disseminated breast cancer were submitted to combination chemotherapy. Fifty one patients (group I) were sequentially given VCR, CPM and 5 FU, and seventy three patients (group II) were given ADM, VCR, CPM and 5 FU. The general and haematological tolerance was good and comparable in the both groups of patients: we observed only two severe infectious complications. Bonemarrow hypoplasia, six myocardial ischemia (two of them were lethal) in each group of patients, without any predominance in the group of patients treated with adriamycin. The percentage of objective regression in both groups was respectively: 72% and 71%. The mean duration of response was eight months. The median survival time was 420 days for patients of group I; for patients of group II the median is not obtained at 480 days. This study confirms that responders to chemotherapy significantly increase the mean duration of survival time. However, in this group of responders the presence of the liver metastases is worse prognosis than all other visceral metastases.

The primary site of metastasis of osteosarcoma is the lung. In the past, even if the primary lesion was completely removed by radical surgery, more than 90% of patients of died pulmonary metastasis with in one to two years. Control of osteosarcoma therefore depends upon the prevention and treatment of its pulmonary metastasis. The introduction of chemotherapy consisting mainly of Adriamycin and high-dose methotrexate with Leucovorin rescue, dramatically improved the prognosis of osteosarcoma. In the past where systemic chemotherapy was not available, the five-year survival rate was around 19%. The majority of patients developed bilateral pulmonary metastasis within one year after onset, and died. These patients exhibited numerous micro-metastases as well. In patients receiving surgical adjuvant chemotherapy with current combination of chemotherapeutic agents (ADM, HD-MTX, VCR, CPM, CDDP), the incidence of pulmonary metastasis was low, and the five-year survival rate increased to 65%. In patients who receive chemotherapy, pulmonary metastasis may be either delayed, a single metastasis appearing after the termination of treatment, or early and multiple, appearing resistant to treatment. Surgery is indicated in the former situation while some therapeutic system must be devised for the latter. Recently, preoperative chemotherapy for limb-saving is given to patients with osteosarcoma of the extremities (NSH-3, 4, 5). The adjuvant of chemotherapy proved to be of great significance for improving the survival rate of osteosarcoma and for achieving limb salvage.

Thirteen patients with advanced testicular tumors (seminoma 2, non-seminoma 11) were treated with combination chemotherapy involving BLM, vinca alkaloid and CDDP (BVP) as induction therapy and followed with CPM, VCR and CDDP as maintenance therapy. BVP and COP administration was repeated every 3 and 4 to 8 weeks for 1 year, if there were no serious side effects. The overall response rate (CR + PR) was 92% with a 69% CR rate. At a mean follow-up of 30 months (7-52 month range), 54% of the patients were alive with no evidence of disease. Bulky metastases, failure to respond to prior chemotherapy and teratomatous metastases were considered to be poor prognostic factors. The toxicity of BVP was similar to that reported for CDDP, except that allergic reaction occurred in 3 patients after several courses of treatment. Two of the 3 went into anaphylactic shock.

Invasive colon adenocarcinomas with lymph node metastases can be induced in Sprague-Dawley rats by 15 weekly intrarectal injections of 2 mg N-methyl-N-nitrosourea (NMU). Extracts were prepared from invasive adenocarcinomas and normal rat colon mucosa by a 2 phase gradient. Mixed leukocyte tumor interaction (MLTI) assays stimulating lymphocytes from tumor-bearing and normal rats were performed using these extracts. Quadruplicate cultures were established with 2 X 10(5) lymphocytes and tumor or normal colon extract. Cultures were pulsed with H3 thymidine at 7 days and harvested 6 hours later. Results were expressed as net counts (experimental CPM minus background CPM). Reactivity in tumor-bearing animals was first seen when rat colons showed intraepithelial dysplasia histologically and was maximal when early invasive colon tumors were present. No difference in stimulation was seen between tumor-bearing and normal animal lymphocyte reactivity with normal colon extract. In conclusion, animals with NMU-induced rat colon cancer show specific tumor reactivity in MLTI assays. Immune reactivity in these animals may provide clues to clinical tumor status by immunologic assay.

Clinical Stage IV-S neuroblastoma involving a primary, the liver, bone marrow, and/or skin has a favorable prognosis despite a considerable tumor burden. In a pilot experiment utilizing mouse C 1300 neuroblastoma, we demonstrated that animals receiving tumor to IV-S sites had a prolonged survival. To analyze the role which liver modulation of tumor might play in an immunologically mediated host-antitumor response, we applied an in vitro lymphocyte blastogenesis assay. Host-tumor response as reflected by blastogenesis and as quantified by tritiated thymidine incorporation into DNA demonstrated that normal lymphocytes were stimulated to a greater degree by subcutaneous site tumor than by tumor from the liver (260.7 +/- 71.9 vs. -54.2 +/- 194.3 CPM, p less than 0.05). Sensitized lymphocytes harvested from liver tumor bearers demonstrated a greater response when admixed with subcutaneous tumor in vitro (771.9 +/- 300.4 vs. 45.9 +/- 277.5 CPM, p less than 0.05) and sensitized lymphocytes harvested from subcutaneous tumor bearing animals also demonstrated more in vitro blastogenesis to subcutaneous tumor (577.9 +/- 200.2 vs. 98.9 +/- 154.1 CPM, p less than 0.05). However, host lymphocytes were themselves comparably reactive whether they were harvested from liver tumor or subcutaneous tumor donors (771.9 +/- 300.4 vs. 577.9 +/- 200.2, p = NS). These data suggest that lymphocytes in contact with murine liver neuroblastoma respond less well than when in contact with subcutaneous site tumor, a form of afferent blockade which may account for the propensity of the liver to serve as a site for metastatic disease.

A 53-year-old female with peritoneal metastasis of breast cancer was treated with hyperthermia with chemotherapy. One course consisted of THP 60 mg and FT 400 mg/iv (day 1), CPM 100 mg and MPA 800 mg/daily/po) with RF heating of hyperthermia monthly. After completion of 10 courses of this regimen, ascites completely disappeared and peritoneal metastases were not found observed in any peritoneal cavity with abdominal CT and ultrasound. Peritoneal metastasis of breast cancer was one of the worst reactions with any therapy. The patient has been living for about four years without any signs of recurrence, with the tumor markers within the normal range after surgery. Thermochemotherapy seems a very promising treatment modality for peritoneal metastasis of breast cancer.

We report here on treatment results of consecutive CCLSG NHL studies (NHL855, 1985-1989; NHL890, 1989-1996). The NHL855 protocol consisted of an induction phase of five drugs (VCR, PRD, CPM, DXR, and high-dose MTX) and a maintenance phase of 7 drugs. The probabilities of EFS at 7 years were 78% (SE, 10%) for the patients with localized disease, and 38% (SE, 7%) for those with advanced disease. In the NHL 890 protocol, the patients were assigned to two different treatment groups according to their histology and received different consolidation therapy; non-lymphoblastic subtype was treated almost identically to NHL855 while LASP and VP-16 were newly added for the lymphoblastic subtype. The 7-year EFS improved to 91% (SE, 6%) for localized disease, and 61% (SE, 6%) for advanced disease. A remarkable improvement was particularly evident for lymphoblastic type with mediastinal mass. Optional trial of high-dose sequential chemotherapy and peripheral blood progenitor cell auto grafting resulted in an unfavorable outcome. The 7-year EFS according to main histological subgroups were as follows: 84% (10%) for large cell type, 67% (11%) for Burkitt's-type, 58% (10%) for lymphoblastic type. Secondary cancer occurred in two of the 163 patients studied. Both patients were AML (M0/M4) and MLL rearrangement was detected in the M4 case.

Case 1: A 34-year-old woman,who had a right breast cancer with axillary lymph node metastasis and multiple bone metastases, was referred to our clinic. She developed paralysis of lower extremities and disorder of the bladder and rectum due to metastasis to the thoracic vertebra, and also had renal dysfunction due to severe hypercalcemia and hemorrhagic cystitis. Correcting the serum calcium level with intravenous infusion, elcatonin, pamidronate and betamethasone, she underwent radiation therapy for the vertebral metastasis. The first hormonal therapy (leuprorelin/exemestane) had been effective for about 4 months, however the second hormonal therapy (leuprorelin/tamoxifen) was not effective. Chemotherapy with paclitaxel (80 mg/m(2), day 1, 8, 15, every 4 weeks) brought about a stable general condition and a normal level of serum calcium with zoledronate in the ninth month of treatment. Case 2: A 32-year-old woman, who had a right breast cancer with multiple bone metastases and axillary and hilar lymph node metastases, came to our clinic, complaining of nausea due to severe hypercalcemia. After successful correction of hypercalcemia by the intravenous infusion and administration of elcatonin, pamidronate and dexamethasone, the hormonal therapy(goserelin/tamoxifen) caused rapid re-elevation of serum calcium and tumor marker, so that a tumor flare was suspected. After 3 cycles of EC therapy (EPI 90 mg/m(2), CPM 600 mg/m(2), every 3 weeks), 2 cycles of paclitaxel therapy (80 mg/m(2), day 1, 8, 15, every 4 weeks) brought about tumor reduction and the normal level of serum calcium. After 7 cycles of paclitaxel therapy,the hormonal therapy (goserelin/tamoxifen) proved effective for several months. To achieve tumor reduction and stabilize the serum calcium level, we need to start immediately the treatment of breast cancer with severe hypercalcemia, considering the general condition of the patient.

Well-differentiated (WD) liposarcoma is a low-grade mesenchymal tumor with features of mature adipocytes and high propensity for local recurrence. Often, WD patients present with or later progress to a higher-grade nonlipogenic form known as dedifferentiated (DD) liposarcoma. These DD tumors behave more aggressively and can metastasize. Both WD and DD liposarcomas harbor neochromosomes formed from amplifications and rearrangements of Chr 12q that encode oncogenes (MDM2, CDK4, and YEATS2) and adipocytic differentiation factors (HMGA2 and CPM) However, genomic changes associated with progression from WD to DD have not been well-defined. Therefore, we selected patients with matched WD and DD tumors for extensive genomic profiling in order to understand their clonal relationships and to delineate any defining alterations for each entity. Exome and transcriptomic sequencing was performed for 17 patients with both WD and DD diagnoses. Somatic point and copy-number alterations were integrated with transcriptional analyses to determine subtype-associated genomic features and pathways. The results were, on average, that only 8.3% of somatic mutations in WD liposarcoma were shared with their cognate DD component. DD tumors had higher numbers of somatic copy-number losses, amplifications involving Chr 12q, and fusion transcripts than WD tumors. HMGA2 and CPM rearrangements occur more frequently in DD components. The shared somatic mutations indicate a clonal origin for matched WD and DD tumors and show early divergence with ongoing genomic instability due to continual generation and selection of neochromosomes. Stochastic generation and subsequent expression of fusion transcripts from the neochromosome that involve adipogenesis genes such as HMGA2 and CPM may influence the differentiation state of the subsequent tumor.
