Combined therapy was used on a consecutive series of 48 patients with extrapelvic Ewing's sarcoma at the Rizzoli Orthopaedic Institute. The adjuvant chemotherapy protocol (
VCR
, ADM, D-ACT, EDX) was identical in all patients whereas local treatment consisted of amputation, resection and radiation treatment or radiation alone. At a mean follow-up of 58 months (39-78) 30 patients (60%) were free of the disease. This is a significantly higher percentage than that obtained in the same period with adjuvant chemotherapy using only 3 drugs (
VCR
, ADM, EDX). As far as the type of local treatment is concerned, the percentage of local recurrences and
metastases
was lower when the primary lesion was treated with surgery or surgery combined with radiotherapy, rather than radiation treatment alone. These suggest that if associated with radiation treatment and chemotherapy, surgery can play an important role that should be considered in the treatment of extrapelvic Ewing's sarcoma.

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.

From July, 1978 to September, 1981, 184 patients with localy advanced breast cancer (T3; T4a-b; any N; M0) regardless of their hormonal receptor status, entered a trial to evaluate the contribution of radiotherapy when added to an intensive preoperative chemoendocrine regimen. Seventy-eight patients were ultimately disqualified. All patients underwent sequentially: (1) two cycles of chemotherapy: Day 1--
Oncovin
1.4 mg/m2, cyclophosphamide 350 mg/m2, Adriamycin 30 mg/m2; Day 2--methotrexate 20 mg/m2, 5-fluorouracil 350 mg/m2 (in addition, antiestrogens were given to postmenopausal patients); (2) mastectomy with complete axillary dissection combined with oophorectomy in patients before and one year after menopause; (3) radiotherapy randomly to one-half of the patients; and (4) ten additional chemotherapy cycles as above, with antiestrogens to all patients. No serious local sequellae were encountered from mastectomy or radiotherapy, but complications of chemotherapy were numerous, particularly in irradiated patients. One death due to toxicity occurred after preoperative chemotherapy. The results to date suggest that in irradiated patients
metastases
may become enhanced and that their local disease is not more effectively controlled than in patients not having radiotherapy. Two factors may have been largely responsible for the differences observed between the two groups: the delay of chemotherapy in irradiated patients and the sustained immunosuppression known to occur after mediastinal radiotherapy.

Twenty year's (1959-1979) experience in the treatment of osteosarcoma at the Bone Tumor Center of the Istituto Ortopedico Rizzoli is presented. During this period 433 cases were recorded, but only 266 were considered. All the patients underwent surgery but after 1970 whole-lung irradiation (1971), immunotherapy (1971), and chemotherapy (1972 onward) were added as adjuvant therapies on a nonrandomized basis. In the group treated with surgery alone the prognosis was very poor: 10% survived nine years or more after the diagnosis, an average disease-free interval of 7.7 months and an average survival time of 13 months. Monolateral whole-lung irradiation had negative results and was abandoned after six cases. Adjuvant immunotherapy with irradiated autologous tumor cells gave moderately positive results in 16 patients, but only by delaying the appearance of first
metastases
, therefore increasing the time of survival. Adjuvant chemotherapy was performed with three different protocols: one protocol with ADM only and two protocols using
VCR
+ MTX (at medium dose) + ADM, administered according to two different schedules. Superimposable results were obtained with these three regimens. With equal follow-up, the percentage of continuously disease-free patients treated with adjuvant chemotherapy was significantly higher than that of patients treated with surgery alone (P less than 0.001). The patients in the chemotherapy group who had relapses showed a prolonged time (mean = 12.3 months) to the onset of the first metastasis. Adjuvant chemotherapy caused virtually no morbidity and no deaths. Reference is made to the advantages of a large and homogeneous caseload deriving from a single institution to avoid preselection bias and evaluate the effectiveness of new therapeutic approaches when patient randomization has not been employed.

Synovial sarcoma with pulmonary
metastases
appeared to be sensitive to multiagent chemotherapy of Pirarubicin, Ifosfamide, and
Vincristine Sulfate
. However, this chemotherapy regimen could not be continued because of severe hemorrhagic cystitis due to the toxicity of Ifosfamide. Even in the advanced stage, this multiagent chemotherapy would be useful for the treatment of synovial sarcoma, if hemorrhagic cystitis could be prevented.

This study tested the prophylactic efficacies of doxorubicin hydrochloride and vincristine sulphate, encapsulated in sterically stabilised long circulating liposomes, against the spontaneous development of mammary carcinomas in C3H/He mice. Monthly prophylactic intravenous (i.v.) injections of 6 mg/kg doses of liposome-encapsulated doxorubicin (DOX-SL) or 1 mg/kg doses of liposome-encapsulated vincristine (
VIN
-SL) were begun when retired breeding mice were 26 weeks old. Mice that developed a mammary carcinoma while on the monthly prophylactic protocols were then given weekly i.v. injections of 6 mg/kg DOX-SL or 1 mg/kg
VIN
-SL to test the therapeutic efficacies of the drugs, and to determine whether the tumours were susceptible or resistant to therapy. The monthly prophylactic injections reduced the incidence of first mammary carcinomas from 87/88 (99%) in untreated mice to 24/42 (57%) in DOX-SL-treated mice and to 26/32 (81%) in
VIN
-SL-treated mice. Of the mice that developed a mammary tumour while on the prophylactic protocols, 12 of 30 mice were cured by the weekly therapeutic use of DOX-SL, and the growth of 18 tumours was inhibited. The weekly therapeutic use of
VIN
-SL cured 3 of 8 mice, and inhibited the growth of five tumours. Weekly DOX-SL therapy cured 7 of 22 previously untreated mice. The mean survival of tumour-bearing mice was extended from 24 days in untreated mice to 87 days in DOX-SL-treated mice, which had not received prophylactic treatment.
Metastases
were found in 29 of 54 untreated mice, and in 3 of 72 mice treated with DOX-SL and
VIN
-SL. Toxic side effects were limited to a transient weight loss during the weekly treatments. Drug resistance as a result of treatments was not observed.

In the last 20 years, eleven children with adrenocortical functional tumors were treated in the National Children Hospital of Costa Rica. There were nine females and two males and their ages ranged from nine months to 14 years. Eleven patients had features of virilism, five had stigmas of Cushing's syndrome and three hyperaldosteronism. The clinical diagnosis was established given the symptoms, hormonal tests and radiological and imagenological studies. The histologic diagnosis was carcinoma in six by clinical picture in one, and were adenoma in four. Three patients had regional and distant
metastases
. Four patients with carcinoma were treated by surgery and five received chemotherapy, two of them in presurgical stage, and four received radiotherapy. Two patients with carcinoma are alive and had no evidence of tumor recurrence ten and six years after diagnosis. Five are dead, two of them after partial response to chemotherapy. The four patients with adenoma were cured by complete surgical tumor resection, furthermore one of them received chemotherapy because there was not sure of his histologic benign condition. It is necessary more studies in use of chemotherapy in treatment of this tumors but in our experience CFM,
VCR
, Epi and Actin is a regimen that appears to be an active combination for the treatment in presurgical stage of adrenal cortical carcinoma.

From January 1988 to October 1991, one hundred and twelve patients with non metastatic Ewing's sarcoma of bone were treated with a 6 drugs neoadjuvant chemotherapy protocol (IOR/Ew2) in which, to the four drugs usually used in the treatment of this tumor (vincristine, adriamycin, cyclophosphamide and dactinomycin), Ifosfamide and VP-16 were added. The local treatment consisted of radiation therapy in 52 cases, a surgical treatment was performed in 27 cases and in the remaining 33 cases both the previous treatments were used. At a mean follow-up of 4.5 years (3-6.5), 62 patients (55.3%) remained continuously free of disease and 50 relapsed: 41 with
metastases
, 8 with mestastases and local recurrence and 1 with local recurrence alone. These results do not differ from the ones obtained in our Institution in 98 patients treated between 1983 and 1988 with a neoadjuvant protocol (IOR/Ew1) in which only
VCR
, ADM, CTX and actD were used (3 year CDFS: IOR/Ew2 = 60.7%-IOR/Ew1 = 55.1%). In IOR/Ew2 a higher DFS rate was observed in the patients with tumor located in the axile bones in comparison with that obtained in the previous study (IOR/Ew2 = 48.6%, IOR Ew1 = 25.6%). Despite the fact that these results came from a not-randomized study, the authors conclude that the addition of Ifosfamide and VP-16 to the four drugs standard regimen do not improve the outcome of patients with Ewing's sarcoma of bone, with the possible exception of the patients with tumor located in the axile bones. This data should be confirmed in further and larger studies.

Squamous cell carcinoma of the vulva is a rare disease, mainly seen in elderly women. Risk factors are advanced age, an immunocompromised status, longstanding vulvar dystrophy,
VIN
, a history of vulvar human papillomavirus infection, and a history of cervical cancer. Vulvar cancer should be considered as a skin tumor and detection is possible in an early stage. However, because of patients' and doctors' delay, one in three vulvar cancers is not treated before an advanced stage. The tumor metastasizes mainly lymphatogenic. Spread starts in the inguinal lymph nodes. In the middle of this century, standard treatment, consisting of an en bloc dissection of the vulva and inguinal lymph nodes has been developed and applied. As a result, considerably improved survival rates were achieved: up to 90% 5-year survival rates for patients without lymph node
metastases
. However, complication rates were high. In recent years, a more individualized approach has replaced standard treatment. Surgical treatment now depends on the localization, size and extent of the tumor, and is followed or preceded by radiotherapy in selected cases. The role of chemotherapy in advanced disease is currently being studied in several referral centers. The most important success in the treatment of vulvar cancer in recent years is the maintenance of high survival rates despite considerably less extensive surgical treatment, resulting in lower complications rates. An important challenge for the near future will be the improvement of the management of advanced disease. However, an even more difficult issue may be the prevention of such large lesions. The reduction of treatment delays requires a considerable effort in education of both health care workers and the general public.

The aim of these experimental and clinical studies was to determine if verapamil helps overcome multidrug resistance in tumor cells and in cancer patients. The effect of the calcium channel blocker verapamil on the antiproliferative activity of epirubicin (Farmorubicin, Farmitalia) was followed up in in vitro studies on two constant human leukemia cell lines: CEM/O (P-gp negative) and CEM/
VCR
1000 with a positive multidrug resistant (MDR) phenotype. The MTT assay was used to study the antiproliferative activity. Verapamil in concentrations of 3 and 10 micrograms/ml enhanced by 10-fold and 19-fold, respectively, the effect of epirubicin in CEM/
VCR
1000 cells and had no significant effect on epirubicin activity in CEM/O. Eleven patients with measurable stage IV breast cancer, clinically resistant to anthracycline treatment, received the FEC combination (5-fluorouracil-epirubicin-cyclophosphamide) twice with verapamil pretreatment, p.o. at the doses of 1280-2560 mg. There were two complete remissions (soft tissue
metastases
), four partial remissions (soft tissue
metastases
and lung metastases), and three stable diseases. These studies confirm the possibilities of overcoming multidrug resistance by the administration of verapamil in tumor cells and in cancer patients.
