Surgical second look in ovarian cancer: a randomized study in patients with laparoscopic complete remission--a Northeastern Oncology Cooperative Group-Ovarian Cancer Cooperative Group Study.

PURPOSE: The usefulness of extensive and repetitive surgery for patients with ovarian cancer still remains unproven (at least for some conditions). We planned an accurate prospective test of the hypothesis that patients with advanced-stage disease, after they had reached a clinical complete remission (CR), may benefit from surgical second look (SSL). PATIENTS AND METHODS: One hundred two patients in CR (as assessed by clinical findings, markers, and visualization by computed tomographic [CT] scan and laparoscopy), after initial debulking and first-line chemotherapy, were randomized to two arms, which were well balanced for predictive criteria such as age, stage at presentation, histology, grading, date of randomization, and residua after first surgery. Forty-eight patients were randomly assigned to receive follow-up evaluation only, while 54 were assigned to receive second surgery (eight of them refused). Of 46 surgical patients, 35 had negative and 11 positive surgical findings (24% clinically false-negative). RESULTS: Despite the microscopic residua found at open surgery, and the fact that the patients were then treated with second-line chemotherapy, SSL did not increase the probability of survival in this setting. In an analysis of the results according to the intention-to-treat criteria, after a 60-month follow-up period, the overall survival rates in the two groups of patients (SSL v no SSL) were 65% and 78%, respectively (P = .14). Multivariate analysis according to predictive criteria confirmed there was no significant difference between the two groups (P = .39). CONCLUSION: Our study shows the following: (1) our second-line treatment is scarcely effective; (2) SSL accurately defines complete responders to first-line chemotherapy; (3) SSL per se does not prolong survival; and (4) if confirmed, a less invasive procedure could replace SSL as a valuable method in new first-line regimens in ovarian cancer patients with clinical CR confirmed by laparoscopy.

Increasing 4'-epidoxorubicin and fixed ifosfamide doses plus granulocyte-macrophage colony-stimulating factor in advanced soft tissue sarcomas: a pilot study.

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.

Physicians and death: comments and behaviour of 605 doctors in the north-east of Italy.

The aim of this study was to determine the influence of socio-demographic and professional factors on physicians' attitudes to the terminally ill. Between May 1992 and May 1993, a survey was conducted in the province of Pordenone (north-east, Italy) in order to analyse a number of specific issues, such as emotional involvement, the need for aggressive treatments and the communication of diagnosis and prognosis. After obtaining a list of board-certified physicians from the Medical Association office in Pordenone, a modification of the cancer questionnaire of Haley and Blanchard (QSPT) was mailed to 916 doctors. Of these, 605 (60%; 487 male, 118 female; mean age 41 +/- 11 SD) returned the completed questionnaire. Within the group of responders, we identified three main subgroups, according to their type of activity: general practitioners (175, 29%), hospital doctors (235, 39%) and other doctors (195, 32%). In age, sex and activity, the only significant difference between responders and non-responders was age (mean age 41 and 43 years respectively). Most of the responders (77%) stated that they were able to deal with the terminally ill patient and his/her needs; 44%, however, admitted that patients' anxiety is sometimes unbearable. For the vast majority of the doctors polled (91%), providing a comfortable environment for an incurable patient was more important than pursuing aggressive treatment, but only 44% were convinced of the uselessness of aggressive care. To the question on whether to disclose information about imminent death to allow patients to prepare spiritually, 37% answered "No", 38% "Yes", and 25% were uncertain. Almost all responders (95%), however, believed in the beneficial effect of hope on the terminally ill. Our results suggest that doctors' professional and, most of all, socio-demographic and cultural factors determine the relationship with the patient on both the emotional and the clinical decision-making levels.

A phase II trial of dacarbazine, fluorouracil and epirubicin in patients with neuroendocrine tumours. A study by the Italian Trials in Medical Oncology (I.T.M.O.) Group.

BACKGROUND: Previous experiences in the treatment of neuroendocrine tumours have demonstrated some activity of single agents such as adriamycin, fluorouracil (FU), streptozotocin and dacarbazine (DTIC). Opinions concerning the usefulness of polychemotherapy in carcinoid tumours are discordant, whereas better results have been achieved in other endocrine pancreatic neoplasms. Based on this background, we used multidrug chemotherapy with DTIC, FU and epirubicin in the treatment of different neuroendocrine tumours. METHODS: The study involved 38 pts with progressive and measurable disease. The treatment schedule was FU 250 mg/m2 i.v., epirubicin 25 mg/m2 i.v., and DTIC 200 mg/m2 i.v. on days 1, 2 and 3 every 3 weeks. RESULTS: The responses achieved by histologic types were carcinoids 2/20, medullary thyroid carcinoma 1/7, neuroendocrine tumours 1/6; and Merkel cell carcinoma 3/5. The median duration of response was 5 months (range 2-11). Stable disease was observed in 13 cases (34%). Out of the 18 cases in progression, 17 had not responded to previous medical treatment. No symptom control was observed in 4 pts with carcinoid syndrome. Treatment toxicity was moderate and included nausea and vomiting, alopecia, leukopenia and mucositis. CONCLUSIONS: Our results document the moderate efficacy of the regimen in all of the histologic types. The major difference in comparison with previous studies was the lower response rate observed in patients with neuroendocrine tumours.

Phase II trial of flutamide in advanced ovarian cancer: an EORTC Gynaecological Cancer Cooperative Group study.

New active non-toxic therapeutic regimens are warranted in ovarian cancer relapsing after platinum-based chemotherapy. Some investigators have determined that androgen receptors predominated over oestrogen and progesterone receptors in untreated common epithelial ovarian cancer tissue cytosols. In an effort to test its antitumoural activity, 68 pretreated patients with epithelial ovarian cancer were given flutamide 750 mg/day orally for at least 2 months. Of 32 patients who received a minimum of 2 months of therapy, pretreated with at least one platinum-based chemotherapy, and a median of two chemotherapy regimens, two (6.3%) objective responses (one complete and one partial) and nine (28%) disease stabilisations were observed; these lasted 44 and 72 weeks, respectively (for the complete and partial response), and for a median of 24 weeks for stabilisations (range 12-48+). Nausea and vomiting were the most frequent side-effects. These occurred in 19/55 (34.5%) patients evaluable for toxicity. Flutamide has to be considered ineffective in patients extensively pretreated with chemotherapy, and it is not devoid of side-effects.

Phase I-II intraperitoneal mitoxantrone in advanced pretreated ovarian cancer.

36 previously treated patients (25 with anthracyclines) with advanced epithelial ovarian cancer have been treated with intraperitoneal (i.p.) mitoxantrone (M) at increasing doses. The response was evaluated through repeated laparoscopy with multiple biopsies and serial measurement of Ovarian Cancer Antigen 125 (CA 125); 11/36 patients had a complete (6 patients) or partial (5 patients) response. Toxicity (both local and general) was observed starting from 25 mg/m2 of M per cycle. The amount of drug reaching systemic circulation was monitored by measuring M plasma value after i.p. treatment. This study showed wide variations in serum levels obtained after i.p. doses ranging from 23 to 36 mg/m2. The area under the curve (AUC) of mitoxantrone plasma samples, did not correlate with the i.p. administered dose. Conversely, a correlation seems to exist between the plasma AUC and the responder status. Patients who showed clinical responses to i.p. treatment with mitoxantrone had AUCs and plasma peak levels of the drug that were significantly higher than those in non-responders (P = 0.03, Fisher's exact test).

Experience with intraperitoneal alpha-2a interferon.

Eighteen patients affected with epithelial ovarian cancer have been treated by intraperitoneal alpha 2a-Interferon. The usual single dosage was 54 x 10(6) U at weekly intervals for four times (eight times in responders): 10 histologically confirmed complete remissions and 3 partial remissions have been obtained; the toxicity was represented by fever in the majority of the cases, by abdominal discomfort in some cases, and by a mild transitory neurological complication in 1 case. Seventeen of 18 patients were pretreated, and 11 of 18 had only cytologic and/or microscopic disease. alpha 2a-Interferon has proven to be very effective and moderately toxic in microscopic peritoneal disease of ovarian epithelial cancer previously treated with extensive surgery and intravenous cytotoxic chemotherapy.

Whole abdomen radiation therapy after a short chemotherapy course and second-look laparotomy in advanced ovarian cancer.

From April 1983 through December 1989, 42 consecutive patients with diagnosis of epithelial ovarian carcinoma were initially managed by aggressive surgery and three courses of endoperitoneal cis-platinum-based chemotherapy followed by an alternating combination chemotherapy and second-look laparotomy. Patients with residual tumor less than or equal to 2 cm subsequently received whole abdominal radiation therapy (WAR). Twenty-eight patients (42% with no residual disease, 21% with microscopic disease, and 36% with residual disease less than 2 cm) were eligible for WAR. WAR was delivered using an open-field technique up to 22 Gy in 20 fractions followed by a pelvic boost of 18 Gy in 10 fractions. The kidneys were shielded posteriorly at 1100 cGy; hepatic shields were not added. One patient did not complete WAR for lung metastases after 5 radiotherapy fractions. The complete treatment program lasted 8 months (range, 6.8-11). The median follow-up of the 28 patients entered into the study was 50 months. Eight patients are alive and disease-free at 5 years. The overall and disease-free survival rates at 5 years are 45 and 30%, respectively. All but 2 patients relapsed within the abdominopelvic cavity and 3 developed brain metastases. Toxic effects, during WAR, required treatment interruption in all but 4 patients: 3 developed a small bowel obstruction requiring surgery and 1 died of surgical complications in complete remission. The poor disease-free survival and the severe toxicity encountered have been valid indications that WAR should be discontinued as a treatment modality in advanced ovarian cancer at our department.

Evaluation of two consecutive regimens in advanced gastric cancer.

Treatment of gastric cancer still presents a challenge in cancer chemotherapy. In our Institute, from January 1981 to November 1984, 45 patients were given 5-fluorouracil (5FU) 600 mg/m2 Days 1, 8, 29, and 36; doxorubicin (A) 30 mg/m2 Days 1 and 29; mitomycin-C 10 mg/m2 Day 1 (FAM regimen) every 8 weeks. From December 1984 to October 1986, 26 patients were treated with 5FU 300 mg/m2 on Days 1-5, A 40 mg/m2 on Day 1, cisplatin (P) 100 mg/m2 on Day 1 (FAP regimen) every 3 weeks. In the FAM group, 42 patients are evaluable for response; 5 (12%) partial remission (PR), 9 stable disease (SD), and 28 progressions (PRO) were observed. Median duration of response (MDR) was 21 weeks (range 13-45) and the median survival (MS) in the whole group was 27 weeks. In the FAP group, 23 patients are evaluable: 2 CR (9%), 11 PR (47%), 2 SD (9%), and 8 PRO (34%) were observed; CR duration was 24 and 107+ weeks, respectively, MDR of PR was 22 weeks (5-35). The MS of all patients was 16 weeks. Toxicity (WHO criteria) was mild in the FAM group and severe in the FAP group. In spite of a higher objective response rate, the short MS and the severe toxicity observed in the FAP group do not merit recommendation of this regimen in patients with gastric cancer; therefore neither FAM nor FAP appear to be an ideal standard therapy.

Combination antibiotic treatment of chemotherapy-induced neutropenia in non-leukemic patients.

The use of more aggressive chemotherapies in the treatment of patients with some tumors has caused a higher frequency of neutropenia and subsequent serious infections. To verify the role in these patients of a combination therapy of amikacin (300 mg/m2 i.v. every 12 hours) plus ceftazidime (2 g/m2 i.v. every 8 hours) administered as initial empiric treatment, followed in non-responsive cases by a second-line therapy with clindamycin (300 mg/m2 i.v. every 8 hours), we conducted a prospective study in 45 febrile episodes (temperature greater than or equal to 38.5 degrees C) in neutropenic patients (neutrophils less than or equal to 500/ml). The patients' median age was 58 (range, 19-80); 29 were women and 16 were men. The median performance status was 50 (range, 30-90), and 71% of the patients had progressive tumoral disease. Before antibiotic therapy the median duration of fever was 12 hours (range, 4-48 hours). The median granulocyte count was 350/ml (range, 100-500 cells/ml), and the median peak temperature was 38.8 degrees C (range, 38.5-41 degrees C). The median time for neutrophils to rise towards 1000/ml was 4 days (range, 2-12), and the median duration of therapy was 8 days (range, 3-12). Documented bacterial infections were present in 28 patients whereas 17 had clinically possible infections or fever of unknown origin. The infection sites in microbiologically documented infections were: septicemia (12), multiple sites (4), tonsillitis (4), urinary tract (4), pneumonia (2) and fistula (2). Complete response to first-line therapy was obtained in 36 out of 45 episodes (80%; 95% confidence limits from 65% to 90%). Five out of 8 cases responded to second-line therapy with clindamycin for and overall recovery rate of 91%. The amikacin-ceftazidime combination followed by clindamycin in non-responsive cases is effective, with moderate toxicity in non-leukemic febrile neutropenic patients.

Retrospective analysis of the CYVADIC regimen in advanced soft tissue sarcomas.

We performed a retrospective review of our data obtained with the original CYVADIC regimen in 31 consecutive patients with advanced soft tissue sarcomas. The treatment consisted of cyclophosphamide 500 mg/m2 i.v. from day 1, vincristine 1.5 mg/m2 in days 1 and 5, doxorubicin 50 mg/m2 i.v. on day 1, and dAcarbazine 250 mg/m2 i.v. from days 1 to 5, repeated every 3 weeks. An objective response was observed in 11/31 patients (35.5%). There were 2 complete remissions (6.5%) lasting 23 and 2 months respectively and 9 partial responses (median duration 7 months, range 1-23). No change was observed in 14 patients, and 6 patients showed progression after a median of 2 cycles of chemotherapy. Toxicity was similar to that already described with this regimen, with alopecia, nausea, vomiting and myelosuppression being the most important side effects. In particular, the median WBC nadir was 1,900/mm3 (range 400-3,600/mm3) whereas the platelet nadir was 181,000/mm3 (range 80,000-358,000/mm3); no patient developed congestive heart failure, and no treatment related death was observed. Still today, after 10 years of use, the CYVADIC regimen is very widely employed as a standard treatment for recurrent or metastatic soft tissue sarcomas, although the original positive results have been confirmed only by a few authors. In our retrospective analysis of a totally unselected population of patients, we too observed a lower activity which is, however, according to a recent review, similar to the mean value of responses obtained in the whole population of treated patients reported in the literature.
