High-dose versus low-dose cisplatin in advanced head and neck squamous carcinoma: a randomized study.

From November 1981 to February 1983, 64 patients with advanced head and neck squamous carcinoma were randomly treated with either high-dose (120 mg/m2) or low-dose (60 mg/m2) cisplatin. Of the 62 eligible patients, 59 were evaluable: the response rate observed in patients receiving high-dose and low-dose cisplatin was 16.1% and 17.8%, respectively. Survival was superimposable in the two treatment arms. No evidence of dose dependency of cisplatin activity in advanced head and neck squamous carcinoma was noted in this randomized trial.

Chlorozotocin treatment of advanced gastrointestinal cancer.

From April 1981 to December 1981, 34 consecutive patients with advanced gastrointestinal cancer were treated with chlorozotocin at the dosage of 40 mg/m2 daily for 5 consecutive days (30 mg/m2 in patients pretreated with chemotherapy) every 6 weeks. In the 30 patients evaluable for response, a 3.3% objective response rate was encountered. Toxicity was not significant and consisted mainly in reversible myelosuppression. Median survival was 3 months. At the dosage and schedule used, chlorozotocin does not seem to be an effective agent in the treatment of advanced gastrointestinal cancer.

cis-platinum and etoposide combination chemotherapy of advanced non-oat cell bronchogenic carcinoma.

From December 1981 to November 1982, a consecutive series of 37 patients with advanced non-oat cell bronchogenic carcinoma were treated with cis-platinum and etoposide in doses of 20 mg/m2 and 75 mg/m2, respectively, for 5 consecutive days every 3 weeks. Among the 33 evaluable patients, one complete response, 11 partial responses, five minor responses, seven unchanged states, and nine cases of progression were noted. Median duration of response was 30+ weeks. Toxicity was significant, but no treatment-related deaths were encountered. Combined cis-platinum and etoposide can provide significant palliation in approximately one-third of patients with the doses and schedule used.

Carcinoembryonic antigen (CEA) in the follow-up of disease-free breast cancer patients.

Carcinoembryonic antigen (CEA) assays (2536) were performed in 380 disease-free breast cancer patients after radical mastectomy. In the 334 evaluable patients with 3 or more determinations, the overall relapse rate after a median follow-up of 29 months was 11%. Of 203 patients with normal CEA values, 19 (9.3%) relapsed. In the 50 patients with the highest CEA value greater than 20 ng/ml, the relapse rate was 26%; in the 12 patients with gradually increasing CEA elevations it was 50%. However, CEA was unable to predict recurrence in N- patients. Premastectomy N+ was significantly associated with greater than 20 ng/ml or gradually increasing CEA values, suggesting the lack of an independent prognostic value of CEA in our patient population.

Vindesine in the treatment of squamous cell carcinoma (WHO I), adenocarcinoma (WHO III), and large cell carcinoma (WHO IV) of the lung.

The antineoplastic activity of vindesine was evaluated in 57 patients with non-small-cell carcinoma of the lung, 53 patients were fully evaluable for response and toxicity. Twenty-seven patients had squamous cell carcinoma (WHO I), 14 had adenocarcinoma (WHO III), and 12 had large cell carcinoma (WHO IV). Forty percent of patients were previously treated. Vindesine was administered at a weekly i.v. dose of 3 mg/m2. Partial remissions were observed in 2 of 12 patients with large cell carcinoma and in 1 of 27 patients with squamous cell carcinoma. Among 14 patients with adenocarcinoma, 3 minor responses were observed. Drug-related toxic effects (mainly leukopenia with manageable and reversible neurotoxicity) required modification of dose in 41% of patients: this finding and previous treatment may have adversely affected the response rate. It is concluded that vindesine as a single agent has some activity in large cell carcinoma. Activity in the other histologic types was minimal but not totally absent and deserves further evaluation, possibly in non-pretreated patients.

Phase II evaluation of vindesine in mycosis fungoides, extraosseous plasmacytoma and other hematologic malignancies.

We conducted a phase II trial of Vindesine in 24 patients, mostly pretreated (23/24 fully evaluable for therapeutic response) with advanced hematologic malignancies. The drug was administered at weekly bolus doses of 3 mg/m2 i.v. Overall, objective tumor regressions were seen in 9 of 23 patients. The drug appeared effective in extraosseous plasmacytoma (1 complete response, 1 partial response and 1 minor response in 6 patients). Further phase II trials in these 2 diseases are justified. In addition, 3 partial responses in 7 patients with advanced lymphoma were also obtained. Previous vinca-alkaloid exposure did not adversely affect the response rate: 8 of 9 responsive patients had previously received vincristine and/or vinblastine. Drug-related toxic effects were mainly represented by manageable and reversible neurotoxicity and by moderate leukopenia with apparent lack of thrombocytopenia. In heavily pretreated patients, leukopenia may be occasionally severe: in these conditions a starting dose of 2 mg/m2 seems more appropriate.

Staging and treatment with cyclophosphamide, vincristine and prednisone (CVP) in advanced cutaneous T-cell lymphomas.

Twenty-three consecutive patients with cutaneous T-cell lymphomas were submitted to staging procedures including lymphangiography, bone marrow biopsy and aspiration, peripheral blood morphological examination, peritoneoscopy with liver and spleen biopsy, and in selected patients lymph node biopsies. Extracutaneous disease (lymph nodes, bone marrow, liver and spleen) was detected in 12 patients. Bone marrow was involved in 25 per cent of the patients at presentation (all patients had lymph node involvement) and in two of nine patients with advanced disease during the follow-up. Peripheral blood was involved in 65 per cent of the patients at presentation (ten patients with advanced disease) and in six of nine patients with advanced disease during the follow-up. In 16 patients with advanced disease (T3-T4 and/or extracutaneous disease), CVP was given with a 50 per cent objective response rate and four complete remissions of 47+, 12+, 19 and 19 months duration. Median survival of patients with advanced disease was 4 years.

Parenteral nutrition in cancer patients receiving chemotherapy: effects on toxicity and nutritional status.

The role of total parenteral nutrition (TPN) in reducing toxicity related to cancer chemotherapy (CT) is presently a controversial issue. To evaluate the effectiveness of TPN in reducing CT-associated toxicity and correcting and preventing CT-related impairments of nutritional status, a prospective crossover controlled study was performed in 43 cancer patients (19 normally nourished and 24 malnourished) randomly divided into two groups (A and B). Group A patients received TPN concomitantly with the first course of chemotherapy, and the second course was administered 21 to 28 days later without TPN support; group B patients were treated in the opposite sequence. The rates of myelotoxicities and gastrointestinal toxicities after CT courses with or without TPN were essentially similar in normally nourished and malnourished patients. No changes in nutritional indexes were detected in normally nourished subjects after each course. Conversely, in undernourished subjects, prealbumin, retinol-binding protein, and nitrogen balance increased in CT+TPN courses (p < .02). In CT-only courses, undernourished subjects showed a decrease in prealbumin and nitrogen balance. Significant changes of nitrogen balance in CT vs CT+TPN courses were detected in malnourished subjects. TPN appears to be unable to reduce CT-associated toxicity. CT administration does not result in any impairment of the nutritional status in normally nourished cancer patients. From our study, it appears that TPN should be limited to severely malnourished neoplastic patients undergoing CT, because of its ability to prevent further impairment of nutritional status and to improve the nitrogen balance and the levels of fast-turnover visceral proteins.

Treatment of lymphoma in the elderly: an update.

Recent studies specifically directed toward assessing the outcome of older patients with non-Hodgkin's lymphoma (NHL) indicate that age per se is an important and independent prognostic factor for response and survival. Prospective studies have addressed therapeutic approaches in these patients. Direct comparison of trial results is difficult since different age limits were set for the inclusion of patients in study. These studies suggest that older patients with aggressive NHL should be treated with curative intent. We report on selected prospective clinical trials of the literature and the Aviano Group experience in the treatment of NHL in the elderly. In particular we refer our data of a randomized study (CHOP vs VMP), conducted within the EORTC Lymphoma Group, and the results obtained with chemotherapy and granulocyte colony-stimulating factor.

Treatment of multiple myeloma and acute myelogenous leukemia in the elderly: an update.

The optimal management of hematopoietic malignancies in the elderly requires the development of specific therapeutic strategies based on the peculiar clinico-biologic features of aged patients. Multiple myeloma arising in elderly patients remains at this time an incurable disease, while attention to supportive therapy and palliation can make a great impact on the quality of life. Fortunately advances have been made in last years in this field. Therapy at the time of diagnosis is usually recommended for patients with symptomatic disease, or for those who may be asymptomatic, but have evidence of high tumor burden of a biologically aggressive disease, and may be expected to progress and develop complications over a short period of time. Melphalan combined with prednisone remains the standard therapy choice in elderly patients. Radiotherapy maintains an important place in the palliation of destructive bone disease in poorly controlled myeloma, particularly in elderly patients. In Acute Myelogenous Leukemia, age has been concordantly reported as an adverse prognostic indicator in affecting both remission rates and survival. The overall unsatisfactory therapeutic results appear connected with host-related factors, and intrinsic differences in the biology of leukemia. Patients with standard risk should be included in collaborative trials aimed at improving the long-term results of conventional therapy. Patients with high risk and unfavorable prognostic factors, could be enrolled in controlled studies aimed at better assessing, in the elderly, the long term results of newer drug combinations. A watch and wait strategy, consisting of transfusion support and leukocytosis control, should be limited to patients with extremely poor performance status (PS), very limited life-expectancy and/or severe comorbidity displaying unfavorable biologic factors, including secondary Acute Myelogenous Leukemia.
