The results of 131 cases of classic non-metastatic osteosarcoma of the extremities treated with preoperative chemotherapy, surgery and postoperative chemotherapy are reported. Preoperatively, the patients were given
Methotrexate
(
MTX
) intravenously (high and average doses) and Cisplatinum (CDP) intraarterially. For postoperative chemotherapy, the drugs and treatment protocols were based on the degree of necrosis observed (good, fair, poor). Conservative surgery was performed in 73% of the cases and amputation in 27%. At an average 30 month follow-up (9-48 months) 59.5% of the patients had remained disease-free, 37.5% had developed
metastases
, and 3% had developed local recurrence. The percentage of disease-free patients was higher for those treated with high doses of
MTX
(68% vs. 51%) and for those in whom preoperative chemotherapy had induced good necrosis (75% vs. 44%). Neither the age or sex of the patients, nor the site of the tumor or type of surgery performed influenced prognosis.

Methotrexate
(
MTX
) has demonstrated significant activity against relapsed and metastatic osteosarcoma. However, there is little published data to indicate the appropriate dose for
MTX
when given as a component of a multidrug regimen for the treatment of osteosarcoma. Therefore, the investigators at the Childrens Cancer Study Group undertook a randomized clinical trial that compared Adriamycin and vincristine given with either high-dose methotrexate or moderate-dose methotrexate as postoperation chemotherapy in the treatment of childhood osteosarcoma. We report here the results for 166 patients with completely resected nonmetastatic disease of an extremity. The two therapies demonstrated equivalent disease-free survival (DFS). Further, no therapy prejudices survival after relapse. Approximately 38% of patients remain disease free 4 years after diagnosis. Two relapses occurred in patients free of disease at least 36 months after initiation of treatment. Some factors found by other investigators to be prognostic of poorer DFS, namely, male sex, primary tumor in the humerus or femur, and larger primary tumors, demonstrated similar though not statistically significant trends. The presence of spontaneous necrosis in the tumor sample from the definitive surgery was associated with poor prognosis for DFS. We postulate that this feature represents rapidly growing tumors with increased potential for
metastases
.

With the aim of verifying the in vivo applicability of local hyperthermia combined with chemotherapy, 13 patients with superficial
metastases
from different histologic types of carcinoma, mostly from head and neck cancer, were entered in a pilot study. The chemotherapeutic regimen was cis-platinum, 20 mg/m2/d X 5 days, bleomycin, 10 mg/m2 on days 8 and 12, methotrexate, 100 mg/m2 on day 15, followed after 24 by folinic acid. Hyperthermia, using a microwave apparatus, and chemotherapy were delivered simultaneously. Objective remissions were achieved in 54% of patients, within the hyperthermia field (1 CR and 6 PR). No serious toxicity was noted.
Methotrexate
distribution after local hyperthermia was evaluated in 8 patients. Response duration was not gratifying, except for patients successively treated with radiation. In conclusion, the combination of chemotherapy plus local hyperthermia deserves subsequent evaluation as part of adjunctive programs.

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.

The patient was a 26-year-old male. He was admitted to our hospital with a chief complaint of hemoptysis, cough and left scrotal mass on May 9,1984. Chest X-ray film, LAG and CT revealed multiple lung, lymph node and cerebral
metastases
. Based on a diagnosis of testicular neoplasm, orchiectomy was performed on May 14,1984. PVB chemotherapy (Cis-diamminedichloro-platinum, Vinblastine and Pepleomycin) was administered. Because he got worse, however, he was treated with another combination chemotherapy, consisting of
Methotrexate
(
MTX
, 100 mg/m2 intravenous push (i.v.), 200 mg/m2 12-h infusion, day 1. The dose of
MTX
was increased with each course. Maximum dose of
MTX
was 900 mg/m2/day), Vincristine (1.0 mg/m2 i.v. day 1.) Actinomycin D (10 micrograms/kg i.v. days 3.4.5), Cyclophosphamide (600 mg/m2 i.v. day 3.), Adriamycin (30 mg/m2 i.v. day 8.) and Melphalan (6 mg/m2 p.o. day 8.). After 6 courses of this regimen, distant
metastases
disappeared or were reduced to under one tenth, and complete remission was obtained without severe side effects. The patient was in good health on March 30, 1985.

Pulmonary metastases of a placental choriocarcinoma are common but they are rarely the presenting factor, and whenever there are pulmonary
metastases
in a young woman a systematic search is required. We report on 7 cases and emphasize several important points. The diagnosis rests on the level of Beta H.C.G. One should be cautioned about transparietal aspiration or fibreoptic biopsy in view of the haemorrhagic nature of the lesion. An extensive work-up should be performed before classifying patients as low, medium or high risk as on this will determine the type of chemotherapy, either monotherapy with
Methotrexate
or polychemotherapy. The duration of treatment will depend on the clinical, radiological and biological outcome.

The remarkable improvement has been recently made in the treatment of choriocarcinoma, about 80% of survival rate has been achieved. This improvement was acquired according to appearance and betterment on administration method of
MTX
and ACTG, surgical treatment for pulmonary and cerebral
metastases
and irradiation for cerebral
metastases
. Recent died cases were analysed and divided into two groups; one group consisted of recurrent cases and the other consisted of those who, at first showed good response to therapy resulted in drop of hCG value and reduction of tumor, however, then showed gradual reincrease of hCG and expired at latt. Therefore for achieving the 0% of mortality rate, it is a important subject to exterminate the death from recurrence and clarify more aggressive treatment method at the time when reduction of the tumor is obtained.

High-dose methotrexate with citrovorum factor "rescue" (MTX-CF) produced an apparent complete response of the primary tumor in three patients with osteosarcoma. The response was sustained with
MTX
-CF, intra-arterial cis-diamminedichloroplatinum II (CDP) and Adriamycin (doxorubicin) for 18 months. Treatment was then electively discontinued. Local recurrence occurred in two patients, 6 and 4 months later, respectively.
MTX
-CF was reinstated and a complete response was again achieved in one patient. This has been maintained for 15+ months with
MTX
-CF and intra-arterial CDP administered for 13 of the 15+ months. Reinduction with
MTX
-CF failed in the second relapsed patient but an apparent remission was again achieved with radiation and intra-arterial CDP. This has been maintained with intravenous CDP, cyclophosphamide and phenylalanine mustard for 14+ months. A complete response in the primary tumor was still present in the nonrelapsed patient, 42 months from diagnosis. All patients have remained free of pulmonary
metastases
, 40+ to 42+ months from diagnosis.

Over a 10 year period, between 1974-1984, 257 adult cases of tissue sarcoma have been evaluated in the Department of Medical Oncology, Christie Hospital, Manchester. At registration locally advanced or metastatic diseases was present in 162 (63%). The male/female ratio was 1.5:1 and median age 54 years (range 14-85). The commonest sites were lower limb (33%), visceral (21%), trunk (13%), retroperitoneum (12%) and upper limb (10%). Leiomyosarcoma (27%), liposarcoma (14%) malignant fibrous histiocytoma (10%) and neuro plus fibrosarcomas (15%) were the most frequent histological subtypes. A high proportion of uterine sarcomas (17%) is a point of distinction from many other series. Histological grade was specified in 72% of cases and the distribution (Grade I--27%; II--6%; III--67%) reflected a referral bias towards advanced disease. Local resection of the primary tumour was performed in 76% of cases. In many instances this only amounted to 'shelling out' and true compartmental excisions were rare. Amputation was performed in 31% of patients with limb sarcomas. Ninety-eight patients (38%) had experienced one or more local recurrences prior to referral and the overall local recurrence rate was 56%. Suitable patients (78%) received chemotherapy, 50% entering multicentre trials in collaboration with the EORTC. The commonest regime used in patients with advanced disease was CYVADIC which produced an overall response rate of 37%. Ifosfamide, used as a single agent in 16 patients, induced 3CR and 5PR for an overall response rate of 50%. When used in combination with
MTX
and VADIC, there was no difference in response rate, but numbers in these pilot studies were small. Seventeen high risk patients received adjuvant chemotherapy with VAC, but the results (11 relapses) were disappointing. An EORTC trial, comparing adjuvant CYVADIC chemotherapy with control has accrued 307 patients, 49 of these from the Christie Hospital. Preliminary results within this centre - 13/25 relapses in the control arm, 5/23 in the chemotherapy arm-suggest an advantage for chemotherapy but the data are statistically not significant. Post-operative radical radiotherapy after resection of the primary tumour or local recurrence was performed in 51 patients, with local control in 65% of cases, although
metastases
developed in 41%. At the time of analysis (1st April 1984) 98 (38%) were alive, of whom 72 showed no evidence of disease and 52 had never relapsed. Malignant disease was the cause of death in 92%. Overall survival was not influenced by sex, but patients less than 40 years of age fared significantly better (P less than 0.001).(ABSTRACT TRUNCATED AT 400 WORDS)

In 61 patients (pts.) with biopsy proven osteogenic sarcoma a disease free survival rate of > 80% was obtained using T-7 chemotherapy. This can be explained by successful eradication of pulmonary micrometastases with aggressive chemotherapy. The prognosis for pts. < 12 years was significantly improved since a higher dose off
Methotrexate
was used for this younger age group. The histologic effect of preoperative chemotherapy on the primary tumor is of prognostic value for the outcome of the disease. Pts. with good histologic effect on the primary tumor (grade III and IV effect) show a 100% disease free survival rate, whereas pts. with poor histologic effect (grade I and II effect) have a 50% chance to develop
metastases
. The role of cis platinum in future therapeutic trials is discussed based on the experience with cis platinum in phase II trials.
