Phase II study of elliptinium acetate salvage treatment of advanced breast cancer.

Elliptinium acetate (Celiptium) is an intercalating agent belonging to the ellipticine family. This agent has demonstrated clinical activity as salvage treatment in breast cancer using a weekly regimen. However, its clinical use was hampered by important toxicities such as xerostomia and immune-mediated haemolytic reactions due to development of anti-elliptinium IgM antibodies. We have studied 83 patients previously treated for metastatic breast cancer using elliptinium acetate with a different schedule: 80 mg/m2 daily for 3 consecutive days every 21 days. In 80 evaluable patients, an objective response (complete + partial response) was obtained in 5 of 30 patients with visceral metastases (13%), in 6 of 21 patients with soft tissue metastases (29%), and in 3 of 20 patients with mixed metastases (15%). The overall objective response rate was 14/80 (18%, 95% confidence interval = 10-26%). Moderate to severe xerostomia occurred in 10% of patients, while no anti-elliptinium antibodies or haemolytic reactions were detected using this schedule. No significant haematological toxicity, as usually reported with this drug, was observed. Elliptinium acetate has modest but definite activity as salvage treatment of breast cancer. The 3-week schedule seems as active as and less toxic than the weekly schedule.

[Phase I trial of recombinant human granulocyte-macrophage colony stimulating factor. Results in patients with advanced tumors].

Fourteen patients with advanced solid tumors were included in a phase I trial of recombinant human E coli derived granulocyte-macrophage colony-stimulating factor (GM-CSF) given daily subcutaneously for 10 consecutive days. Dose levels were increased from 250 micrograms/m2 to 500, 750 and 1,000 micrograms/m2. Adverse effects were mainly fever, local irritation, lethargia, arthalgia. Three patients did not complete the 10-day cycle: one patient died due to progressive disease without toxic effects related to GM-CSF, one was withdrawn because of suspicion of pulmonary embolism (not confirmed), one patient had hypotension, not recurring after treatment with GM-CSF. Although the maximum tolerated dose was not reached, the trial was stopped at 1,000 micrograms/m2, considering the satisfactory response and the high white blood cell counts observed with lower dose levels. N-fold increases of leucocyte count ranged between 4.2 and 8.2 for the first dose level (250 micrograms/m2), 4 and 10.1 for 500 micrograms/m2, 8.5 and 12.3 for 750 micrograms/m2 and 5.6 and 8.3 for 1,000 micrograms/m2. Increases of granulocyte, neutrophil and eosinophil counts had a similar pattern with a weaker response at 1,000 micrograms/m2 (two patients who completed the cycle). In contrast, even for the first three levels, no dose response relationship was shown for increases of monocytes (between 2.8 and 12 n-fold whatever the dose), or lymphocytes (between 1.7 and 10.7 n-fold whatever the dose). Decreases of platelets (between 6 and 55%) were observed, followed by a rebound after stopping treatment. No modifications of erythrocyte count were observed. Subcutaneous GM-CSF was well-tolerated up to 1,000 micrograms/m2 during a 10-day course. Hematological effects were observed from the first dose level of 250 micrograms/m2.

[Treatment of advanced breast cancer in postmenopausal women with droloxifene: results of a double-blind phase II trial for dose determination].

To determine the optimal daily dose of a new antiestrogen, droloxifene, for the treatment of advanced breast cancer, we have conducted a multicenter, randomized, double blind trial. Postmenopausal women with advanced breast cancer, who could not benefit from loco regional therapy, with positive or unknown estrogen or progesterone receptors were entered in this study. Droloxifene was administered in a double blind randomized design, with daily dose of either 20 (group I), 40 (group II) or 100 mg (group III). None of the patients had received previous systemic antitumor therapy, with the exception of adjuvant chemotherapy terminated at least one year before the patient's recruitment. Patients with at least one measurable tumoral lesion were entered into the trial. Three hundred and sixty nine patients have been enrolled, 234 are fully evaluable for efficacy. Objective response rate (CR + PR) is 31.1, 44.6 and 41.9% for the groups I, II and III respectively (P = NS). Time to response has been short: in the three groups, 50% of the responses have been observed within the 2 first months of treatment. Time to disease progression is 6, 8.3 and 6 months respectively for the 20, 40 and 100 mg/day treatment group. Side effects have been moderate and not dose related. Hot flushes and gastro intestinal disorders have been observed most often. This promising new drug deserves further study and randomized comparison versus tamoxifen.

[A multivariate prospective study of prognostic factors in 200 operated epidermoid cancers of the esophagus. Definition of patients for whom surgical resection was of benefit].

From 1982 to 1991, 200 patients with squamous-cell esophageal cancers underwent operation. Sixteen prognostic parameters were prospectively collected and analyzed. The main aim of this study was to define the best preoperative criteria for selection for curative surgery and which patients would benefit most from radical resection. Squamous-cell head and neck carcinoma was associated in 43.5% of cases. Of these, 24% preceded the esophageal carcinoma while 19.5% were synchronous. Resection was curative (i.e. grossly complete) in 144 cases, palliative (leaving gross tumor behind) in 25 cases, and judged impossible in 31 cases. Twenty-one patients died during their hospitalization. Five-year survival, according to the Kaplan-Meier method, was 18 +/- 3.6% for all patients, and 27 +/- 4.8% for patients undergoing curative resection (including postoperative mortality). Palliative resections or invasion of adjacent organs, but not resection with positive lymph nodes, was thought to be synonymous with incurability. Multivariate analysis showed that the two principal statistically significant characteristics were the stage as determined by roentgenological and endoscopic evaluation (P = 0.003) (clearly assessable during initial work-up) and type of resection (complete or not) (P = 0.04). Tumor diameter, as determined on CT-scan (< or > than 30 mm), was at the limit of statistical significance (P = 0.09). A second multivariate analysis of prognostic factors was conducted in 128 patients undergoing resection with curative intent and who survived the initial postoperative period. Roentgenologic/endoscopic staging alone emerged as being statistically significant (P = 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Does malignant small round cell tumor of the thoracopulmonary region (Askin tumor) constitute a clinicopathologic entity? An analysis of 30 cases with immunohistochemical and electron-microscopic support treated at the Institute Gustave Roussy.

The morphology and clinical outcome of 30 patients with malignant small round cell tumors located in the thoracopulmonary region (Askin tumor) are reported. Histologically, all tumors had similar patterns, with small round-to-oval cells and a lobulated stroma. Immunohistochemical analysis always resulted in positive staining for one or several neural markers. No significant differences were found compared with the immunomarkers in 26 typical Ewing's sarcomas located outside the thoracic wall. In three specimens, electron microscopy confirmed the presence of membrane-bound neurosecretory granules. It was confirmed that there is a remarkable similarity among all malignant small round cell tumors, including Askin tumor and Ewing's sarcoma. Overall survival was poor with a 2-year rate of 38% and a 6-year rate of 14%.

Phase II study of a combination of elliptinium and vinblastine in metastatic breast cancer.

Thirty nine patients with metastatic breast cancer, all previously treated with chemotherapy including anthracycline, were given Elliptinium acetate (80 mg/m2/day) and a continuous infusion of Vinblastine (2 mg/m2/day) for 3 consecutive days every 4 weeks. Twenty nine patients had measurable metastatic disease. Nine (31%) achieved a partial response. No complete response was observed. Median duration of response was 6 months. The response rate was dependent on the number of metastatic sites and independent of the number of previous chemotherapy regimes. Side effects were dry mouth (27 patients), vomiting (9), neutropenia (3 patients with grade IV, 2 with grade III), muscle cramps (5) and thrombosis (3). Xerostomia and vomiting contributed to weight loss and fatigue (8 patients). We conclude that Elliptinium-Vinblastine combination has moderate activity as second line treatment in metastatic breast cancer. This combination causes xerostomia and fatigue with moderate myelosuppression.

Neoadjuvant chemotherapy in multiple synchronous head and neck and esophagus squamous cell carcinomas.

A consecutive series of 22 patients with multiple synchronous squamous cell carcinomas of the upper aerodigestive tract was retrospectively reviewed. These patients were treated initially with cis-platinum combination chemotherapy before definitive locoregional therapy (surgery and/or radiation therapy). Sixteen of 21 patients had simultaneous head and neck and esophageal primaries, 3 patients had multiple synchronous head and neck primaries, 2 patients had head and neck (HN) and a bronchial epidermoid cancer, and 1 patient had simultaneous esophageal and bronchial carcinomas of epidermoid lineage. Sixteen (77%) of the 21 patients responded to chemotherapy in all the tumor sites evaluated, and a clinically complete response was obtained in 6 (29%). After definitive locoregional treatment, the complete local control rate was 68%, with 34 complete responses for 50 primary tumor sites in 21 patients. Twelve patients were free of disease after locoregional treatment. Six patients are still alive 27 to 57 months after complementary definitive locoregional treatment and a minimum follow-up of 27 months. Median survival for the overall group is 17 months. The response to chemotherapy is remarkable, which may be due to the small tumoral volume present in many of the cases (T1 to T2). Nevertheless, the present report stresses the importance of an aggressive combined therapeutic approach in this difficult clinical situation.

[Neurosarcoma associated with Von Recklinghausen disease: apropos of 25 cases observed at the Gustave Roussy Institute from 1967 to 1990].

In the absence of systematic immunohistochemistry investigations, only 25 cases (out of 69) clearly diagnosed as neurosarcoma due to the association with Von Recklinghausen disease (ie, neurofibromatosis type 1) and treated at the Institut Gustave Roussy were included in the present study. Neurosarcoma consists of a neurocristopathy whose cells migrate to several parts of the body in order to constitute neuroglia, Schwann cells, pigmented and endocrinal tissues. From 1967 to 1990, 25 cases of such neurosarcomas associated with a neurofibromatosis type 1 were seen at our institute. Three different histological terms exist for this tumour: malignant schwannoma, neurosarcoma, and more recently, malignant peripheral nerve sheath tumours (MPNST). The median age (23 years) of the patients with neurofibromatosis type 1 is lower than that of patient with isolated neurosarcoma. Their sex ratio is 2/1. Primary tumour surgical exeresis was performed in all cases, with poor results in 7. Post-operative radiation therapy was not systematically used in this series. It was administered only in cases with incomplete surgical exeresis or when a local recurrence occurred. Adjuvant CYVADIC (doxorubicin, procarbazine, cyclophosphamide, vincristine) chemotherapy was administered in 5 cases, of in cases of relapse (8). All cases but 2 (the most recent ones) relapsed within 1 to 226 months (median 7 months). In addition, 13 patients developed metastases. Overall, the 2-year and 4-year survival rates were 41% and 18%, respectively. Our observations confirm the very poor prognosis for the association of neurofibromatosis type 1 and neurosarcoma. This finding should lead to systematically associate radical surgical exeresis, post-operative irradiation and adjuvant chemotherapy in the treatment of these patients.

[Metastases from cancers of unknown primary site. Data from 302 autopsies].

The autopsies of 302 patients who had metastases from cancers of unknown primary site were studied. In two-thirds of the cases the metastases were located in the lymph nodes, the lungs and the bones. The primary tumour was found in 82 patients when still alive (27 percent) and in 173 patients (57 percent) at autopsy. It could not be identified in 16 percent of the cases. The primary tumours most often discovered were in the pancreas (26.5 percent), the lungs (17.2 percent), the kidneys (4.6 percent) and the colorectal bowel (3.6 percent). On the whole, the paraclinical examinations performed for diagnostic purposes had been disappointing. The survival rate was the same whether or not the primary tumour had been identified. The number of inaugural metastases seems to be a major prognostic factor. These highly progressive tumours must represent a very distinct clinical and biological neoplastic entity. A simple approach and a unicist practical management are suggested.

[Phase I trial of a recombinant human interleukin 2. Results in patients with disseminated solid tumors].

A phase I trial of Roussel-Uclaf recombinant human interleukin 2 (IL 2) was performed on 31 cancer bearing patients of the Institut Gustave-Roussy, Villejuif, and the Institut Curie, Paris. This study allowed to define a schedule for administration of IL 2 in continuous infusion over 5 day cycles. This schedule is manageable in patients without major visceral failure. It is reproducibly feasible in conventional medical oncology units, without specialized intensive care facilities. Toxicities, although numerous, are acceptable for IL 2 doses below 24,000,000 IU/m2/day. There is a close relationship between secondary effect severity and IL 2 doses received. Main toxicities were: fever with chills, fatigue and general discomfort in 23 patients, nauseas and vomiting in 12, diarrhea in 10 and cutaneous rashes with erythema and dermal vascularitis in 13. One peculiar feature of this study was the minimal occurrence of manifestation related to leaky capillary syndrome prominant in other studies. Oliguria, functional renal failure and edema were observed in only 4 patients with functionally unique kidney. Five patients had severe anemia, 2 grade III thrombocytopenia, 1 grade IV hepatic cytolysis, 4 severe confusion episodes and 2 hypothyroidism with anti-thyroid microsome auto-antibodies. All these toxicities were reversible after withdrawal of IL 2 treatment. During this phase I trial, 3 therapeutic objective responses were observed, all 3 occurring in patients with metastatic melanoma treated with IL 2 doses equal to, or above 16,000,00 IU/m2/d. Recombinant IL 2 Roussel-Uclaf thus can be administered through a simple, manageable and efficient regimen.

M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) for advanced carcinoma of the bladder. The French Federation of Cancer Centers experience.

70 patients with advanced transitional cell carcinoma of the bladder received methotrexate, vinblastine, doxorubicin and cisplatin (M-VAC). Complete responses (CR) were obtained in 13 of the 67 (19%) evaluable patients and partial responses (PR) in 25 patients for an objective response rate of 57% (95% CI 45-69%). Of the 54 patients who have had a minimum follow-up of 2 years, 8 patients (15%) are disease-free or have stable residual disease. Median survival of the 70 patients was 13 months. Toxicity was acceptable with no drug-related deaths. Because of myelosuppression, only 15 patients (21%) received treatment without delays in drug administration or modifications from the planned schedule. Our results confirm that this regimen is effective, with some patients being long-term survivors.

[Chemotherapy of soft tissue sarcoma in adults].

The results of several studies of chemotherapy in treatment of soft tissue sarcomas of adults (except embryonic rhabdomyosarcoma) are presented. Most of these studies have been performed and published by the EORTC Bone and Soft tissue sarcoma group. In advanced disease, a randomized trial including 551 evaluable patients and comparing doxorubicin alone (75 mg/m2 q. 3 weeks), and two combination regimens: DI (Doxorubicin (50 mg/m2) + Ifosfamide (5 g/m2 + mesnum q. 3 weeks), and Cyvadic (Doxorubicin 50 mg/m2 d1, DTIC 750 mg/m2 d1, VCR 1.5 mg/m2 d1 (maximum 2 mg/m2), Cyclophosphamide 500 mg/m2 d1 q. 3 weeks), failed to prove any significant difference between these 3 treatments for response rate (25%, 31%, 28%), quality of the response and survival. There is a dose/effect relationship doxorubicin, it is possible that if combination is not superior to a single agent, the reason could be that the dose of doxorubicin is too low when used in combination as compared with the dose when used alone. So, in a phase II trial including 48 evaluable patients, optimal dose of doxorubicin (75 mg/m2 and Ifosfamide (5 g/m2) was given in association with rhGM-CSF. The response rate observed with this combination was 50%. For localized disease, in a randomized trial of the EORTC including 374 evaluable patients with resectable tumors with a mean follow-up of 44 months, the interest of 8 Cyvadic as adjuvant chemotherapy after adequate locoregional treatment (surgery with or without radiotherapy) was demonstrated only for locoregional relapse free survival but no for metastatic disease free survival or overall survival.(ABSTRACT TRUNCATED AT 250 WORDS)

[Fotemustine: a pilot phase II trial in sarcoma of the soft tissues].

Fotemustine has been administered to 10 patients with metastatic or redux soft sarcoma in a phase II pilot study. The main inclusion criteria were: at least one measurable site, Karnofsky index (KI) higher than 60%, no specific treatment within the last 4 weeks, correct haematological status. Induction treatment comprised fotemustine 100 mg/m2 D1-D8-D15 in a 1 h intravenous infusion protected from light, followed by a 5-week rest period. In patients with no progressive disease, maintenance treatment comprised fotemustine 100 mg/m2 D1 q 3 weeks, until progression or toxicity. Patients characteristics were: 9 M/1 F; median age: 51 years [26-66]; median KI 90% [60-100]; median number of previous drugs: 5 [2-8]; 6 patients had two or more metastatic sites and one patient had developed a sarcoma following chest radiotherapy. Evaluation was carried out in weeks 4 and 8, following the first fotemustine injection. One case of minor response and one case of stabilisation were observed, but they were of short duration. The main toxicity was haematological with delayed leucopenia and thrombopenia (nadir: week 6). In patients who have undergone previous chemotherapy, fotemustine is not efficient according to the first step of the Gehan statistical guidelines.

Surgical and chemotherapeutic treatment of hepatic metastases from carcinoma of the breast.

To date, no five year survival rates have been reported for patients with hepatic metastases (HM) from breast origin treated by chemotherapy or hormone therapy. This study was done to evaluate whether or not surgical excision of such metastatic disease associated with chemotherapy has any effect on such a poor prognosis. Between May 1985 and September 1988, 22 patients with a diagnosis of isolated (solitary or multiple) HM have been surgically treated. The therapeutic approach also included systemic preoperative and postoperative chemotherapy. Laparotomy findings for those 22 patients are presented. There were benign hepatic lesions in four patients (four different histologic types) and hepatectomy was done in two patients. Diffuse metastatic disease contraindicated any attempt at hepatic resection in six patients. Hepatectomy was possible in 12 patients. There was no postoperative mortality and minimal morbidity. One-half of the patients with metastases had one or more positive lymph nodes at the hepatic pedicule. Median survival time for 12 patients treated by hepatectomy was 37 +/- 9 months after hepatectomy and 42 +/- 3 months after the discovery of HM. Eleven patients had other metastases after an average period of 11.8 months after hepatectomy, and the liver was the first site of recurrence in eight. One patient underwent a hepatectomy twice. Two patients were free of disease 29 to 46 months postoperatively in spite of poor prognostic features on the excised specimen. Although the median survival time was two times better than with usual treatment, we believe this procedure is of doubtful benefit. In this situation, hepatectomy acts as cytoreductive surgical treatment, with the main limiting factor being the relatively low effectiveness of chemotherapy. This type of therapy can be applied only to a restricted number of patients, and if we decide to proceed with this study, we will have to modify the protocol of chemotherapy radically.

[Synchronous cancers of the esophagus and of the ORL area: results of combined treatments with esophagectomy (28 cases)].

Twenty-eight patients with synchronous esophageal and head and neck epidermoid cancers have been treated by a combined protocol including esophagectomy. Seventy-nine percent received pre-operative chemotherapy, 50% had resection of the head and neck lesion at the same time as the esophagectomy and 79% received post-operative irradiation. Two patients died during the post-operative period (7%), and 1, 2 and 3-yr survival rate (Kaplan-Meier) was respectively 64, 32 and 27%. Contrary to our initial assumption, there was no significant decrease in survival compared to patients operated on for an isolated esophageal cancer. The patients were divided into 4 very simple prognostic groups based on the T and N stages of the clinical pre-therapeutic TNM classification: T1 or T2 for esophageal lesions and different T or N stages according to the prognosis for head and neck lesions. A study of each group tended to show that esophagectomy was beneficial except in cases of synchronous T2 esophageal cancer and locally advanced head and neck cancer (there was 2-yr survival in this group). The 28 patients studied represent a particular population which presented 91 cancerous localisations during the duration of the study (mean: 3.25 localisations per patient).

A phase I trial with recombinant interferon gamma (Roussel UCLAF) in advanced cancer patients.

A total of 29 patients with advanced malignancy were treated with recombinant interferon gamma (rIFN gamma, specific activity = 2.10(7) units/mg, purity greater than 95%) given by intravenous bolus at doses escalating from 0.01 mg/m2 to 5 mg/m2 (2 x 10(5) - 10(8) IU/m2) in nine successive steps (at least 3 patients/step). Injections of rIFN gamma were repeated every 72 h for 15 days. Toxicity was evaluated according to the WHO scale. Fever and chills occurred in all patients treated without clear dose effect. Nausea and vomiting appeared at the fifth dose level and their frequency seemed to be dose-related. Cardiovascular side-effects (first-degree atrioventricular reversible block) were observed at the 2 mg/m2 and 5 mg/m2 levels (3 patients). Hematological toxicities were mild (2 grade 1 and 1 grade II cases of granulocytopenia). Minor biological modifications included a transitory rise in hepatic enzymes (12 patients), which correlated with the presence of liver metastasis. Hypocholesterolemia was observed in 18 patients. The appearance of antibodies against rIFN gamma was not detected. One partial clinical response was observed in a patient receiving 2 mg/m2. During rIFN gamma therapy this patient had the highest scores in this series for peripheral T lymphocytes with an activated phenotype (HLA DR+, TAC+) = 15% and for natural killer (NK) cells (NKH1, Leu19+) = 17%. rIFN gamma appears as a well-tolerated and promising therapeutic agent with toxicities and mode of action probably distinct from IFN alpha and beta.

Therapeutic strategies in inflammatory breast carcinoma based on prognostic factors.

Prognostic factors were identified in a group of 210 patients with inflammatory breast carcinoma (IBC) treated at Institut Gustave Roussy from 1976-1985 with three successive induction protocols: Group A (n = 91), 1976-1980, doxorubicin, vincristine, methotrexate (AVM); Group B (n = 79), 1980-1982, doxorubicin, vincristine, cyclophosphamide, methotrexate, 5-fluorouracil (AVCMF); Group C (n = 40), 1983-1985, AVCMF. Groups A and B received 3 courses of respective chemotherapy (Ct) followed by radiotherapy (Rt), 45 Gy to breast and nodes and 65-70 Gy to the tumor. Group C after the third Ct course received split courses of Rt to equivalent doses so there was no time lag between Ct courses. Ct from fourth to ninth courses was AVM in all groups. Hormonal therapy, radiocastration (pre and perimenopausal) or tamoxifen (postmenopausal) was given all patients. Clinical characteristics of age, menopausal status, castration, N status, and degree of clinical inflammation (limited to tumor area [PEV 2] or involving the entire breast [PEV 3]) were similar in all groups. Groups B and C had identical disease-free and overall survivals, superior to Group A (p = 0.005). In multi-variate analysis, AVCMF was one of the important prognostic factors together with PEV and N status.(ABSTRACT TRUNCATED AT 250 WORDS)
