Morphology of the cervical vertebrae in two caucasian ethnic groups.
A morphometric study of the cervical vertebrae was carried out on 63 Italian skeletons and 58 Asiatic Indian skeletons. The results indicate that there are considerable differences in the vertebral dimensions between ethnic groups of the same racial type. In a high proportion of both groups the mean sagittal diameter was less than 12 mm, which contradicts current opinion that this is the dividing line between the normal and the stenotic canal.

Vinorelbine and mitomycin C in anthracycline-pretreated patients with advanced breast cancer.
At present, there is no satisfactory treatment for advanced breast cancer patients who have become refractory to anthracyclines. Vinca alkaloids and mitomycin C (MMC) are among the drugs most frequently used in this setting. Recently, vinorelbine (VNR) has been reported to be highly active in advanced breast cancer. Sixty advanced breast cancer patients previously treated with anthracyclines have been exposed to VNR 25 mg/m2 i.v. on days 1 and 8, and MMC 10 mg/m2 i.v. on day 1, with cycles repeated every 4 weeks. There were 3 complete and 21 partial responses for an overall response rate of 40% (CI 95%: 28-52%). Median duration of response and median survival were 7 and 10 months, respectively. Myelosuppression was the dose-limiting toxicity, but it was generally mild to moderate. Although this combination appears to be effective and well tolerated, every effort should be made to further improve treatment results in anthracycline-pretreated advanced breast cancer.

Sequential subcutaneous thymopentin, interferon alpha-2a and interleukin-2 in metastatic renal cell cancer.
To determine the activity of sequential administration of thymopentin (TP-5), interferon alpha-2a (IFN) and interleukin-2 (IL-2) in metastatic renal cell cancer (RCC), 17 patients with RCC were treated with TP-5 50 mg/d on days 1 to 14, IFN 3 MIU/d on days 14, 15, 21, 22 and IL-2 18 MIU/d on days 16 to 20, and 23 to 27. Treatment was given subcutaneously and cycles were repeated every 6 weeks. All patients were assessed for toxicity and response. No objective responses were observed. Two patients had a short-lived disease stabilization. Median survival was 9 months. Toxicity was generally moderate. The most important side-effects were related to IL-2 administration. In view of the lack of antitumor activity, the combination of TP-5 + IFN + IL-2 in the doses and schedule used in this trial cannot be recommended. The investigation of chemotherapeutic and immunological agents that can effectively synergize with IFN or IL-2 is essential.

Single-agent ifosfamide in the treatment of anthracycline-refractory adult sarcomas.
OBJECTIVE: The objective of this trial was to assess the therapeutic activity and toxicity of ifosfamide (IFO) with mesna uroprotection as salvage therapy in patients (pts) with soft tissue sarcomas (STS) who had failed high-dose epirubicin treatment. PATIENTS AND METHODS: IFO was administered at a dose of 2.0 g/m2 daily for 5 consecutive days by a 2-h i.v. infusion every 3 weeks. RESULTS: Partial responses were observed in 5/31 (16%) evaluable patients, whereas in other 5 pts the disease remained stable. The median duration of response was 8 months. The median overall survival was 6.5 months. The most common toxicity was hematologic with grade 3 or 4 neutropenia occurring in 47% of the pts. Neurologic toxicity was infrequent, but in 1 patient treatment discontinuation was needed because of severe mental confusion and disorientation. CONCLUSIONS: Although IFO can be of value in a minority of pts with anthracycline-refractory STS, more active agents and new salvage cytotoxic regimens should be investigated in this disease.

[Gemcitabine in advanced stage soft tissue sarcoma: a phase II study].
PURPOSE: To assess the activity and toxicity of gemcitabine in locally advanced or metastatic soft tissue sarcoma patients (pts). PATIENTS AND METHODS: Gemcitabine was administered on days 1, 8, 15 every 4 weeks at a dose of 1.000/1.250 mg/m2, respectively, in pretreated or not pretreated pts. RESULTS: Eighteen pts entered this phase II trial; sixteen had been previously treated with anthracyclines and ifosfamide. A partial response was observed in a woman with fibrous malignant istocytoma, whereas in 7 pts the disease remained stable. Median time to progression was 4 months. The treatment was well tolerated. Grade 4 toxicity was not observed. CONCLUSIONS: These results do not suggest that gemcitabine, in the dose and schedule used in this trial, may be of value in the treatment of soft tissue sarcomas.

[Chemotherapy of advanced stage melanoma using cisplatin, epirubicin and alpha-interferon].
PURPOSE: To evaluate the activity and toxicity of cisplatin (DDP), epirubicin (EPI) and interferon alfa-2a (a-IFN) in patients (pts) with metastatic melanoma. PATIENTS AND METHODS: Thirty-seven pts with histologically-proven metastatic melanoma were treated with DDP 75 mg/m2 e.v. and EPI 90 mg/m2 e.v. on day 1 + alpha-IFN 9 MUI/die s.c. on days 4 to 8 and 18 to 22. Cycles were repeated every 4 weeks. RESULTS: Characteristics of the patients were the following: median age 55 years (range, 24-75), median WHO performance status 1 (range, 0-2), prior chemotherapy 9, prior immunotherapy 16 (adjuvant/advanced 11/5), sites of disease: soft tissue only 10, lung 22, liver 11, bone 1, brain 3. In 35 evaluable patients we have obtained 3 complete and 10 partial responses, for an overall response rate of 37%. Dose-limiting toxicity was myelosuppression with grade (G) 4 neutropenia in 59.5% of patients and G4 thrombocytopenia in 11% of patients. Other toxicities were generally mild to moderate with nausea and vomiting in 67.5% of patients, flu-like syndrome in 78.5% and fatigue in 48.5% of the patients. Median time to response, median time to progression and survival were 3 (range, 2-6), 7 (range, 2-45+) and 10 months (range, 4-45+), respectively. CONCLUSION: This combination is active and well tolerated in metastatic melanoma. Toxicity was manageable and has enabled us to conduct this trial on an outpatient basis.

[Clinical guidelines for the management of gastrointestinal stromal tumors].
Treatment of gastrointestinal stromal tumors (GIST) has been revolutioned by the recently discovered molecular mechanism responsible for the oncogenesis of this disease. In addition, due to the rapid progress at molecular and clinical level observed in the last few years, there is a need to review the current state of the art in order to delineate appropriate guidelines for the optimal management of these tumors. A panel of experts from several specialities, including medical oncology, surgery, pathology, molecular biology and imaging, were invited to participate in a meeting to present and discuss a number of pre-selected questions, and to achieve a consensus according to the categories of the National Comprehensive Cancer Network (NCCN) and the Standard Options Recommandations (SOR) of the French Federation of Cancer Centers. Generally, consensus points were from categories 2A of the NCCN and B2 of the SOR. Conventional histologic examination with immunohistochemistry for CD117, CD34, SMA, S-100 and desmin is considered standard. Molecular analysis for the identification of KIT and PDGFRA mutation may be indicated in CD117-negative GIST. Complete tumor resection with negative margins is the optimal surgical treatment. Adjuvant imatinib should be considered an experimental approach. Neoadjuvant imatinib is also experimental, although its use may be justified in unresectable or marginally resectable GIST. Imatinib should be started in metastatic or recurrent disease, and should be continued until progressive disease or drug intolerance. In these cases, sunitinib can be used. The optimal criteria for the assessment and monitoring of GIST undergoing imatinib therapy are not well known, but they should include reduction in tumor size and disease stabilization, as well as reduction of tumor density on CT scan and metabolic activity on PET scan.

Morphometry of the lumbar vertebrae. An anatomic study in two caucasoid ethnic groups.
A morphometric study of the lumbar vertebrae of 121 skeletons, 63 Italian and 58 Indian, revealed that the mean dimensions of the spinal canal, the lateral recesses, and the vertebral body were significantly greater in the Italian than in the Indian skeletons. The lowest normal limits of the midsagittal diameters of the spinal canal were 12.6 mm in the Italian skeletons and 11.5 mm in the Indian series. The midsagittal diameters of the canal measured, at one or more levels, 10.1-10.8 mm in 5% of the Italian skeletons and 9.0-10.5 mm in 10% of the Indian skeletons. In most vertebrae with midsagittal dimensions of the canal less than 11.5 mm, the width of the recesses was at or below the lower limits of normal. These observations cast doubt on the current view that a midsagittal diameter of the vertebral canal of less than 12.0 mm is pathologic and suggest that the diagnosis of developmental stenosis can not be based only on the dimensions of the spinal canal. Lateral recess stenosis may occur in a normally sized spinal canal but is more likely to occur in developmentally narrow canals.

Dexrazoxane cardioprotection in advanced breast cancer patients undergoing high-dose epirubicin treatment.
PURPOSE: We performed a randomized trial to evaluate the cardioprotective effect of dexrazoxane (DEX) in advanced breast cancer patients (ABC) treated with high single-dose epirubicin (EPI). A secondary objective was to determine the role of radioimmunoscintigraphy (RIS) in the assessment of epirubicin cardiotoxicity. PATIENTS AND METHODS: Ninety-five patients with ABC were treated with EPI 160 mg/m2 by i.v. bolus every 3 weeks with or without DEX, 1,000 mg/m2 i.v. Cardiac monitoring included multigated radionuclide (MUGA) scan with determination of resting left ventricular ejection fraction (LVEF), and RIS with 111-Indium antimyosin monoclonal antibodies. RESULTS: The overall response rate was 69% in the EPI arm and 67% in the EPI + DEX arm; median time to response and median time to progression were identical in both arms, being 2 and 8 months, respectively. Median survival was 19 months versus 29 months (p 0.21), respectively. DEX did not appear to contribute to extracardiac EPI toxicity. Congestive heart failure occurred only in the EPI arm (2 instances). LVEF significantly decreased from baseline only in the EPI group. An abnormal tracer uptake at RIS was observed early in both arms, but the increase in heart to lung ratio was much more evident in the control group. CONCLUSIONS: DEX significantly protects against the development of high dose epirubicin cardiotoxicity apparently without evidence of an adverse impact on antitumor activity and non cardiac toxicity. RIS is a very sensitive technique in detecting anthracycline cardiac damage, but its specificity is low and cannot be considered alone a primary test for guiding anthracycline treatment.

[Phase II study of docetaxel in patients with advanced stage soft tissue sarcoma].
PURPOSE: To evaluate the activity and toxicity of docetaxel (TXT) as second line therapy in advanced soft-tissue sarcoma. PATIENTS AND METHODS: Adult patients (pts) with histologically proven locally advanced or metastatic soft tissue sarcoma, were treated with TXT at a dose of 100 mg/m2 in a 1-hour i.v. infusion every 21 days and steroid premedication with oral prednisone 50 mg twice a day for five days starting 24 hours prior to TXT. RESULTS: From November 1995 to May 1997, 19 pretreated pts entered the trial. Characteristics of the pts: males/females 11/8, median age 58 years (30-74), median WHO performance status 1 (0-2); histotypes: leiomyosarcoma 6 pts, malignant fibrous histiocytoma 6 pts, fibrosarcoma 2 pts, others 5 pts. No objective responses were seen. The disease remained stable in 8 pts (42%). Median time to progression was 3.5 months (range, 2-8), median survival 6 months (range, 2-20). The treatment was well-tolerated: the main side effect was hematological toxicity with G3/4 leukopenia and neutropenia in 58% of the pts; G3 anemia and thrombocytopenia occurred only in 1 case. Other toxicities were alopecia that was universal, G3 emesis in 1 pt, G3 diarrhea in 2 pts, G3 stomatitis in 1 pt. Mild fluid retention was recorded only in 2 pts. CONCLUSIONS: The results of this study do not suggest the use of TXT at this dosage and schedule in advanced soft tissue sarcoma.
