Abstract
The authors take into consideration all types of treatment used at the Rizzoli Orthopaedic Institute and in associated centers over the last 40 years for soft tissue sarcoma of the limbs. For each clinical study the most up-to-date results are reported with statistical evaluations. From the first protocol that used adriamycin alone and up to the beginning of the eighties, we then go on to a second-generation study in the nineties that used adriamycin and ifosphamide at a high dosage. The pilot study that was used at the end of the nineties to evaluate the validity of the use of chemotherapy and radiotherapy is considered, as is the study currently being conducted by the Italian Sarcoma Group. Conclusions based on our vast previous experience lead us to believe that adjuvant chemotherapy must be used for all patients with high-risk soft tissue sarcoma within clinical trials.

Abstract
Treatment of retroperitoneal soft tissue sarcomas is a difficult clinical problem. Despite the improvement in resection rates in the most recent surgical series, local control still remains the main problem because of the high incidence of local recurrences after surgery. Postoperative radiation therapy has not been always successful because of dose-tolerance of surrounding normal structures, which prevent the delivery of adequate doses of radiation. To overcome this limitations, new therapeutic approaches including external-beam radiation and intraoperative radiation therapy (IORT) have been evaluated at some Institutions. The results of IORT with or without external-beam radiation are reviewed and our experience with preoperative radiation and IORT is reported. As treatment of retroperitoneal sarcomas has evolved into combined modalities including preoperative radiation, maximum surgical resection and IORT, a possible improvement in local control rates has been achieved. However, locoregional failures and the incidence of distant metastases remain a challenge, emphasising the need for further improvement in local and distant treatment. The new phase II trial, activated within the Italian Sarcoma Group, with preoperative concurrent chemo-radiation therapy and IORT is presented.

Abstract
Ifosfamide and anthracyclines are the only active agents in advanced soft tissue sarcomas. Doxorubicin was always used in sarcomas, whereas ifosfamide was reintroduced in the clinic after the discovery of mesna which prevents its typical dose-limiting toxicity: hemorrhagic cystitis. In the adjuvant setting, doxorubicin was used alone or in combination in the first-generation trials, whereas its parent compounds epirubicin and ifosfamide were employed in the second-generation adjuvant trials, which started in the early 90s. Other relevant aspects of the second-generation trials are the use of the hematopoietic growth factors and the increase of the dose intensity, the introduction of more restrictive selection criteria and the use of the two most active agents, ifosfamide and anthracyclines. Only the Italian cooperative trial has been concluded, and the results reported and updated. After a median follow-up of 89.6 months (range 56-119), the intention-to-treat analysis still reveals a difference in overall survival which, however, is not statistically significant. However, the 5-year overall survival estimate, which is a reasonable end point for the survival analysis of adjuvant treatment in soft tissue sarcomas, was 66.0 and 46.1% for the treatment and the control groups, respectively (p = 0.04).

Abstract
AIMS The aim of this study was to report prognostic factors, end-points of local recurrence, distant recurrence, post-metastasis survival, and overall survival in a cohort of patients with soft tissue sarcomas. METHODS We analysed a database of 395 patients affected by primary soft tissue sarcomas of various primary sites, treated and followed up at the Centro di Riferimento Oncologico, Aviano, Italy from January 1985 to January 1997. RESULTS Grade, size, stage, surgical margins, distant metastasis, age, sex, performance status, and haemoglobin value were significant for overall survival. Histology, grade, stage, and surgical margins were significant for local recurrence. Grade, size, and stage, were significant for distant recurrence; and surgical margin was significant variable for post-metastasis survival. CONCLUSIONS Grade, size, and TNM stage (UICC/AJCC) have stronger prognostic significance for overall survival and distant recurrence than for local relapse. Positive surgical margins are the main predictors for local relapse. Age was the most consistent adverse independent prognostic factor for survival.

Abstract
Cancer is often associated with paraneoplastic syndromes, which may be misinterpreted. We report a case of a patient with occult small cell lung cancer that was initially compounded by clinical features of a paraneoplastic neurologic syndrome. The presence of antineuronal antibodies and positron emission tomography scan guided the search for the underlying tumor. Following chemo-radiotherapy the patient showed no evidence of disease for the next 18 months, whereas only a slight improvement in the neurologic disorders was observed. The course of the small cell lung cancer was very indolent and the paraneoplastic neurologic syndrome did not worsen with the use of cisplatin.

Abstract
PURPOSE Adjuvant chemotherapy for soft tissue sarcoma is controversial because previous trials reported conflicting results. The present study was designed with restricted selection criteria and high dose-intensities of the two most active chemotherapeutic agents. PATIENTS AND METHODS Patients between 18 and 65 years of age with grade 3 to 4 spindle-cell sarcomas (primary diameter > or = 5 cm or any size recurrent tumor) in extremities or girdles were eligible. Stratification was by primary versus recurrent tumors and by tumor diameter greater than or equal to 10 cm versus less than 10 cm. One hundred four patients were randomized, 51 to the control group and 53 to the treatment group (five cycles of 4'-epidoxorubicin 60 mg/m(2) days 1 and 2 and ifosfamide 1.8 g/m(2) days 1 through 5, with hydration, mesna, and granulocyte colony-stimulating factor). RESULTS After a median follow-up of 59 months, 60 patients had relapsed and 48 died (28 and 20 in the treatment arm and 32 and 28 in the control arm, respectively). The median disease-free survival (DFS) was 48 months in the treatment group and 16 months in the control group (P =.04); and the median overall survival (OS) was 75 months for treated and 46 months for untreated patients (P =.03). For OS, the absolute benefit deriving from chemotherapy was 13% at 2 years and increased to 19% at 4 years (P =.04). CONCLUSION Intensified adjuvant chemotherapy had a positive impact on the DFS and OS of patients with high-risk extremity soft tissue sarcomas at a median follow-up of 59 months. Therefore, our data favor an intensified treatment in similar cases. Although cure is still difficult to achieve, a significant delay in death is worthwhile, also considering the short duration of treatment and the absence of toxic deaths.

Abstract
BACKGROUND The combination of paclitaxel (P) and carboplatin (C) is an effective treatment for advanced NSCLC. Gemcitabine (G) is an active new drug. We planned a phase I study to find the maximum tolerated dose (MTD) of the PCG combination. A phase II study was subsequently conducted to evaluate the activity and toxicity of PCG. PATIENTS AND METHODS Forty-five patients entered the study. Twenty-eight had stage IIIA-B disease, 17 stage IV. In the phase I study, with a fixed dose of C at AUC = 6 on day 1, P was escalated using increments of 25 mg/m2 starting from 175 mg/m2 on day 1 and G with increments of 200 mg/m2 starting from 800 mg/m2 on day 1 and 8. RESULTS Fourteen patients entered the phase I study. The MTD was reached at P 200 mg/m2, C AUC = 6 and G 1000 mg/m2. Neutropenic fever and grade 3 diarrhea were the dose limiting toxicities. Thirty-one patients were treated in the phase II study with P 175 mg/m2, C AUC = 6 and G 1000 mg/m2. Response rate was 57% (68% in stage III and 47% in stage IV). Myelosuppression was the main toxicity, with grade 3-4 leukopenia occurring in 35% of cases. Grade 3 anemia was observed in 24% of cases and grade 3-4 thrombocytopenia occurred in 34% of patients. Non-hematological toxicity was mild. Median survival and one-year actuarial survival were 20.5 months and 74% for stage III and 11.5 months and 47% for stage IV. CONCLUSIONS PCG is a promising regimen for treating advanced NSCLC. A phase III study comparing PCG to paclitaxel plus carboplatin in advanced NSCLC is ongoing. On the other hand, we are planning to introduce the PCG regimen in the treatment of stage II-III patients in the setting of a multimodality treatment.

Abstract
A patient affected by metastatic prostatic carcinoma and hypogonadotropic hypogonadism (HH) was treated with flutamide 750 mg/day plus an LH-RH analog. After confirmation of basal castration during treatment, he continued with antiandrogens alone. Following the normalization of gonadic function and subjective mild bone flare-up, the patient resumed the initial treatment and obtained a partial response. When flutamide was interrupted because of liver toxicity, the patient showed progressive disease in the bone, which was unresponsive to both flutamide resumption and salvage hormone therapy (bicalutamide). The patient is currently receiving chemotherapy with VP16 and estramustine phosphate and is showing both serologic (PSA) and symptomatic response. The interest of this case lies in the incidental detection of HH during therapy and in the responsiveness to treatment.

Abstract
Ifosfamide is a leading drug in soft tissue sarcoma therapy. Recently high dose therapy (>9 g/m2) has been introduced in different schemes to obtain a higher response rate. All these higher doses can be administered following two different schedules: continuous infusion 24 hours a day for 4-5 days or bolus administration for 5 consecutive days. In this study we compare the differences in the pharmacokinetic profile between the two schedules. In both schemes we saw a very important autoinduction phenomenon, with a corresponding half-life decrease and total body clearance increase during the days of therapy. The clearances were not directly correlated with the administered dose. We can conclude that ifosfamide continuous infusion therapy is equivalent to fractionated administration, at least from a pharmacokinetic point of view. Short-term infusion is subjectively better tolerated and is therefore preferred.

Abstract
AIMS In an attempt to reverse multidrug resistance, in a recent trial of verapamil in association with doxorubicin, we used escalating doses of continuous intravenous (i.v.) verapamil under close haemodynamic monitoring. We report the pharmacokinetics of escalating doses of verapamil. METHODS We studied nine patients [seven males, two females; median age 46 years (range, 31-57)] with advanced adenocarcinoma of the colon and normal renal, hepatic, and cardiac functions. After a loading dose (0.15 mg kg-1 followed by 12 h continuous i.v. infusion at 0.20 mg kg-1 h-1), the infusion rate (ko) of verapamil was increased every 24 h (0.25, 0.30, 0.35, and 0.40 mg kg-1 h-1). The highest rate was maintained for 48 h. Doxorubicin was given as a continuous i.v. infusion from 12 to 108 h (n = 4) or 60 to 108 h (n = 5). Blood samples and urine collections were taken every 12 h. Verapamil and nor-verapamil were assayed by high performance liquid chromatography. We calculated systemic clearance of verapamil (CL = ko/Css) and renal clearance (CLr) of verapamil and nor-verapamil. The Css vs rate relationship was fitted to a Michaelis-Menten equation: Css = ko. (K(m)+Css)/(V.Vm). RESULTS CL was dose-dependent and in all nine patients a significant reduction in CL was observed over the dose range (mean CL +/- s.d. were 0.51 +/- 0.31, 0.38 +/- 0.16, 0.32 +/- 0.18, and 0.27 +/- 0.11 l h-1 kg-1, respectively, at 0.25, 0.30, 0.35, and 0.40 mg kg-1 h-1; P = 0.0001). Css increased more than proportionally to the dose rate and the Css vs rate relationship was best defined by a Michaelis-Menten equation (K(m) = 730 micrograms l-1; V.Vm = 0.55 mg kg-1 h-1), (r = 0.994; P = 0.006). CLr of verapamil and nor-verapamil was not saturable but the contribution to the elimination was only 2 to 4% of the dose. CONCLUSIONS These findings suggest a non-linear, capacity-limited metabolic clearance of high-dose verapamil. Using escalating infusion rates, high verapamil concentrations (1500-2500 ng ml-1) were achieved without major toxicity. Saturable clearance may cause higher bioavailability and slower elimination of verapamil after acute oral overdoses.

Abstract
PURPOSE To determine the maximum-tolerated dose (MTD) of 4'-epidoxorubicin (EPI) in combination with full dose of ifosfamide (IFO) when granulocyte-macrophage colony-stimulating factor (GM-CSF) was used, to estimate its clinical efficacy, and to evaluate the mobilization of hematopoietic progenitors. PATIENTS AND METHODS Previously untreated advanced patients were treated with fixed doses of IFO at 1.8 g/m2/d for 5 days and escalating doses of EPI. The starting dose level of EPI was 50 mg/m2 bolus on days 1 and 2; subsequent levels were 60 mg/m2 and 70 mg/ m2 given on days 1 and 2. GM-CSF (5 micrograms/kg/d) was administered from days +6 to +19. Clinical evaluation of response was performed after three consecutive cycles. Mobilization of hematopoietic progenitors was evaluated as day 14 CFU-GM after the first cycle only. RESULTS Overall, six, 18, and 13 assessable patients were entered onto each EPI dose level, respectively. The first and the second EPI level were considered feasible. Conversely, at the third level, only six of 13 patients [46%] tolerated full EPI doses at the scheduled time. Therefore, the dose-intensity of the three levels was 100%, 99.7%, and 86.1%, respectively. Overall, 20 of 37 patients (54%) obtained an objective response. The response rates for the three EPI dose levels were significantly different [17%, 33%, and 100%, respectively; test for trend, P < .001]. Considering only lung metastases, the overall response rate was 72% (20%, 66%, and 100% for the three EPI levels, respectively). The most relevant mobilization effect was obtained at the third EPI level, when both GM-CSF and IL-3 were used as in vitro-stimulating factors. CONCLUSION The third EPI level (70 mg/m2 on days 1 and 2) is the MTD of this program, since it was administered, without dose reduction or treatment delay, for three consecutive cycles in less than half of the patients. Nevertheless, this level proved to be interesting with regard to response rate (13 of 13 objective responses) and in mobilization of the hematopoietic progenitors.

Abstract
BACKGROUND The tumor suppressor protein p53 is overexpressed in a large fraction of human tumors. It has been supposed that p53 abnormalities may be an early event that contributes to the neoplastic transformation; alternatively, p53 overexpression might be related to progression toward more aggressive tumor phenotypes. The aim of the present work was to better clarify the role of p53 overexpression in human soft tissue sarcomas (IISTS). DESIGN p53 immunohistochemistry analysis using the Pab 1801 was performed in frozen samples of HSTS obtained from 61 patients. Tumors were classified according to the WHO criteria, histologic grading was based on the criteria of Enzinger and Weiss, and DNA ploidy and S-phase determination was performed by flow cytometrical analysis. RESULTS Of all the HSTS we analyzed, p53 protein over-expression occurred more frequently in G3 grade tumors (p < 0.01), HSTS of III A-B stage (p = 0.02) and in aneuploid tumors (p < 0.01). CONCLUSIONS The association of p53 overexpression with parameters of biological aggressiveness suggests an involvement of p53 in the neoplastic progression of HSTS. This assumption is supported by the findings that in tumors with a mixed diploid/aneuploid neoplastic cell population p53 protein expression was significantly (p < 0.01) higher in the aneuploid cell subpopulation. In conclusion, our study suggests that overexpression of p53 is present mainly in the most biologically aggressive forms of HSTS and may therefore represent a neoplastic progression index possibly useful for prognostic purposes.

Abstract
BACKGROUND To evaluate the feasibility, toxicity and efficacy of the combination of (IFO) ifosfamide and epirubicin (EPI) given at conventional doses for monochemotherapy, we started a phase II study in advanced/metastatic soft tissue sarcoma patients. PATIENTS AND METHODS Treatment consisted of: epirubicin 75 mg/m2 i.v. day 1; IFO 1.8 g/m2 days 1 to 5; MESNA 20% of the IFO dose at 4-hour intervals three times a day during IFO administration. Cycles were given every 3-4 weeks for at least three cycles. RESULTS The overall response rate for non-visceral sarcomas (51 pts) was 31% (95% confidence limits +/- 13%). Among the 13 visceral sarcomas no response was seen for the leiomyosarcomas of the gastrointestinal tract, whereas one complete and one partial remission were observed for the uterine sarcomas. The duration of response was 10 months (range 5-34+) for complete responses and 9 (range 4-42+) for partial responses. The median survival for responders is 18 months (range 2-60+) and for non-responders 10 months (range 1-33) (p < 0.004). CONCLUSIONS This combination proved to be feasible and tolerable. The overall response rate does not appear to be superior to those with other standard treatments, but it should be pointed out that our patient population was totally unselected.

Abstract
Tolerability and efficacy of the new uroprotective agent ARGIMESNA was assessed within a randomized cross-over study comparing it to sodiummercaptoethanesulfonate (MESNA), in patients treated with IFO. MESNA i.v., 20% of IFO dose, was given to all patients before chemotherapy; 4 h later, at random, they received ARGIMESNA p.o., 20% of IFO dose every 2 h x 4, or MESNA p.o., 40% of IFO dose every 4 h x 2. Overall, 78 cycles of oral uroprotection were administered: 37 for ARGIMESNA capsules; 41 for MESNA vials p.o. ARGIMESNA was subjectively better tolerated, determining gastro-intestinal discomfort in only 12 out of 37 cycles versus 34/41 of MESNA p.o. (p less than 0.001). Both preparations were equivalent for subjective and objective efficacy since no cycles were complicated by urinary symptoms (dysuria, stranguria, or hematuria). Nevertheless, 2 patients (7.7%) refused further oral assumption of both uroprotectors, whereas MESNA i.v. was added in other 7 patients because of nausea and vomiting caused by chemotherapy. In conclusion, this new oral preparation of mercaptoethanesulfonate turned out to be well tolerated, safe and active in the prevention of haemorrhagic cystitis from IFO.

Abstract
Between May 1985 and July 1990, 45 patients (pts.) with primary (39) or recurrent (6) soft tissue sarcomas of the extremities (82%), torso (11%) and head and neck (7%) were treated with radiation therapy and conservative surgery. Seven pts. not amenable to conservative surgery underwent preoperative radiation therapy whereas 38 pts. underwent local excision and post-operative radiation therapy. Out of the 38 pts. managed by postoperative radiation, 24 (63%) showed negative surgical margins and 14 (37%) positive margins, their tumor being adjacent to vital structures. Preoperative radiation allowed conservative surgery in all 7 pts. with initially inoperable tumor; surgical margins were negative in 5 and positive in 2 pts. Twenty-six pts. (58%) had tumor greater than or equal to 5 cm (5-24) and 19 (42%) less than 5 cm (2.5-4.5) in diameter. High grade tumors (G2-G3) were reported in 41 pts. (90%). In pts. treated postoperatively the radiation dose was 64-66 Gy/32-33 fractions and the pts. treated preoperatively received a dose of 50 Gy/25 fractions. Median follow-up was 33 months and all pts. had a minimum follow-up of 12 months (12-72). Three pts. (6.5%) had local failure and 9 (20%) developed distant metastases with local tumor control. All distant metastases occurred in AJC stage IIIB, 9/18 (50%), with an increased frequency by tumor size. Overall local control and disease free survival rates at 5 years (product-limit method) were 93% and 73%, respectively. An evident decrease in disease-free survival rate (33%) was noted for stage IIIB pts.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Human soft tissue sarcomas (HSTS) in adults are a family of mesenchymal tumors characterized by high biological aggressiveness and general refractoriness to chemotherapy. A series of 36 HSTS, 24 untreated and 12 homogeneously treated with a presurgical chemotherapeutic regimen consisting of doxorubicin (intra-arterial) and iphosphamide (intra-vein), was analyzed for expression of MDR1 and the glutathione-S-transferase-pi (GST-pi) gene in order to identify molecular phenomena which may be implicated in the chemoresistance displayed by these tumors. The MDR1 gene was expressed in a greater percentage of drug-treated tumors and at higher levels than in untreated ones. By contrast, chemotherapeutic treatment has no effect on GST-pi mRNA expression. The GST-pi expression level (EL) was much higher in the HSTS with biologically aggressive features. In fact, significant correlations were observed between GST-pi and histologic grade (p = 0.01); aneuploidy (p less than 0.01); and histone H3 EL (p = 0.01), suggesting a possible causal relationship between GST-pi activity and biological aggressiveness in HSTS.

Abstract
The toxicity profile and the pharmacokinetics of aphidicolin glycinate, a water-soluble analogue of aphidicolin, have been evaluated in two consecutive phase I clinical studies. In the first study, aphidicolin glycinate was given by 1-hour infusion for 5 consecutive days, every 3 weeks (daily x 5 study); in the second study, which was planned on the basis of the pharmacokinetic information obtained in the previous study, the drug was given by 24-hour continuous infusion. Treatment was repeated every 3 weeks. In the daily x 5 study, the daily dose was escalated from 12 mg/m2 to the maximum tolerated dose of 2250 mg/m2. Local toxicity was dose limiting. Elimination half-life was 2 +/- 0.2 hours (mean +/- SE) with aphidicolin being undetectable 6-8 hours after the end of the infusion. In the 24-hour continuous-infusion study, the dose was escalated from 435 mg/m2 to the maximum tolerated dose of 4500 mg/m2. Local toxicity was dose limiting, while other toxic effects were absent. The experimentally determined concentrations at the steady state were in agreement with those predicted on the basis of the available pharmacokinetic data. The targeted concentration at the steady state of 3 micrograms/mL was achieved at doses greater than or equal to 3000 mg/m2. Twenty-four-hour continuous infusion is the recommended schedule for clinical evaluations of aphidicolin glycinate as the synchronizing agent or in combination with cisplatin.

Abstract
Fifty-two consecutive patients, affected by large T2 (greater than 3 cm), T3, T4, N0, or N1 previously untreated squamous cell carcinoma of the head and neck, entered this phase I-II study. Treatment consisted of a continuous 8-day infusion on the following daily schedule: cisplatin 25 mg and bleomycin 15 mg administered for 4 and 20 hours, respectively. Technical-related toxicities were 1 case each of coagulation and displacement of the catheter and 1 case of reversible monoparesis of the contralateral arm. Drug-related relevant toxicities accounted for 4 cass of grade 3 or 4 leukopenia and 2 cases of peripheral palsy of the 7th and 12th cranial nerve, respectively. Forty-five of 50 evaluable patients obtained an objective response. In particular, 13 patients obtained a complete response, 22 a partial response greater than or equal to 75%, and 10 a partial response greater than or equal to 50%. Furthermore, 5 of 31 patients showed a complete pathologic disappearance of the tumor, whereas in 12 of 31 only a microscopic residue was found.
