ABSTRACT
OBJECTIVE: We carried out a phase II trial with BEMP [bleomycin, vindesine (Eldisine(R)), mitomycin C and cisplatin] in patients with recurrent and/or metastatic squamous cell carcinoma of the uterine cervix with the specific aim to assess whether BEMP was of particular interest when certain disease sites were involved. PATIENTS AND METHODS: Eligible patients received four cycles of E 3 mg/m(2), day 1 + 8; P 50 mg/m(2), day 1; B 15 mg/day (continuous infusion), day 2-4 and M 8 mg/m(2), day 5 (on alternate cycles), every 3 weeks during an induction phase. Thereafter, those without progression continued with MEP every 4 weeks in a maintenance phase. MEP consisted of E 3 mg/m(2), day 1 + 8, M 6 mg/m(2) (on alternate cycles) and P 50 mg/m(2), both on day 1. All drugs were given i.v. Both response evaluation and toxicity grading were assessed according to World Health Organization criteria. RESULTS: Of the 161 eligible patients, 143 were assessable for survival, 148 for toxicity and 131 for response. Overall response rate was 45% [complete (CR) 14.5%, partial response (PR) 30.5%]. Most responsive disease sites were lung, lymph nodes and skin metastases (>60% response, CR rate >25%). Median duration of response was 7.6 months. Survival was significantly better in patients with only distant metastases: 12.9 months versus 8.6 months in those with other disease sites involved (P = 0.002). In a multivariate analysis, patients with a good performance status yielded a better prognosis (P = 0.0017), as did the patients with only metastatic disease compared with those who had pelvic disease also or solely (P = 0.045). There were two toxic deaths and 21% of patients stopped treatment because of excessive toxicity. CONCLUSIONS: Patients with a good performance status and only distant metastases seem optimal candidates to receive the BEMP regimen. This benefit should be balanced against the expected serious toxic effects.

30 patients with advanced ovarian cancer, all platinum pretreated, were treated with an induction cycle of fotemustine. Maintenance therapy was given to 6 patients. No objective response was observed among the 21 evaluable patients. The main toxicities were gastrointestinal, with grade 3 nausea and vomiting reported in 40% of the patients, and haematological, with grade 4 leucopenia reported in 2 patients and grade 4 thrombocytopenia in 5 patients. Therefore, no role has been demonstrated in our cohort for the use of fotemustine, a nitrosourea, in pretreated ovarian cancer.

PURPOSE: To evaluate the feasibility and toxicity of continuous 7-day-a-week pelvic irradiation with no breaks between external beam irradiation and intracavitary applications. MATERIAL AND METHODS: Between November 1998 and December 1999, 30 patients with FIGO Stage IIB or IIIB cervical cancer were treated with continuous 7-day-a-week pelvic irradiation, to the total Manchester point B dose of 40.0-57.6 Gy. The first 13 patients (group A) were applied a daily tumor dose of 1.6 Gy and the remaining 17 patients (group B)-10.8 Gy. One or two immediate brachytherapy applications (point A dose 10-20 Gy, each) were performed in 28 cases. RESULTS: Two patients did not complete the irradiation due to apparent early progression of disease during the irradiation. Of the remaining 28 evaluable patients 11 (39%) completed treatment within the prescribed overall treatment time and 17 had unplanned treatment breaks. For the latter group overall treatment time ranged from 103 to 122% (mean 114%) and from 103 to 197% (mean 138%) of the planned treatment time for group A and B, respectively. The majority of patients experienced acute toxicity. Severe toxicity (EORTC/RTOG grade 3 and 4), predominantly gastrointestinal, occurred in 5 of the 13 patients in group A, and in 7 of 17 patients in group B. CONCLUSION: The studied regimen was accompanied by considerable toxicity, hindering delivery of irradiation within planned treatment time.

OBJECTIVE: To investigate the clinical activity and toxicity of a combination chemotherapy consisting of cyclophosphamide (C), adriamycin (A) and cisplatin (P) for patients with primary adenocarcinoma of the Fallopian tube having FIGO stage III-IV disease. METHODS: The CAP-regimen consisted of cyclophosphamide 600 mg/m2, adriamycin 45 mg/m2, and cisplatin 50 mg/m2 administered intravenously on day one every 28 days. RESULTS: Twenty-four eligible patients with histologically-confirmed Fallopian tube adenocarcinoma were entered in the trial. Fourteen patients had FIGO stage III, and ten had stage IV disease. The median number of CAP cycles was six. Ten patients had a complete and six had a partial response (response rate: 67%, 95% confidence limits: 45-84%). WHO grade III-IV side-effects included haematological toxicity, nausea/vomiting and alopecia. Furthermore, mild signs of cisplatin-related peripheral neurotoxicity were observed. At a median follow-up of 40 months, nine patients were alive and 15 had died due to malignant disease. The median time to progression was 13 months for all patients. The median overall survival was 24 months and the 1-, 3- and 5-year survival and their 95% confidence limits were 73% (54-92%), 25% (4-46%) and 19% (0-38%), respectively. CONCLUSION: The present data confirm the therapeutic activity of the CAP-regimen in primary Fallopian tube adenocarcinoma. The response rate is moderate and the toxicity profile is acceptable.

BACKGROUND: In vitro data demonstrated a dose-response relationship for doxorubicin in ovarian cancer cell lines. However, this dose-response question for anthracyclines has never been adequately addressed in ovarian cancer patients. A phase I study with epirubicin gave support to these in vitro findings and recommended a dose of 150 mg/m2 for phase II testing. PATIENTS AND METHODS: The present report concerns the final analysis of an EORTC-Gynecological Cancer Cooperative Group (GCCG) phase II study of high-dose epirubicin (HDE) in cisplatin-pretreated patients with epithelial ovarian cancer. A total of 100 eligible patients were included; 34 had progressed during first-line therapy (group 1), 17 had persistent disease after first-line therapy (group 2) and 49 had relapsed following an initial response to first-line therapy (group 3). All patients had measurable or evaluable disease, were aged < 75 years, had a WHO performance status 0-2, had adequate vital organ function and gave consent. Epirubicin was administered by rapid i.v. infusion at a dose of 150 mg/m2 and given at three-week intervals. Escalation to 180 mg/m2 was to be carried out if white blood cell nadir count was > 2.0 x 10(9)/l and platelet nadir count was > 75 x 10(9)/l. RESULTS: A total of 361 HDE treatment cycles were administered, the median number per patient being 4. Of the 85 patients who received at least two cycles of protocol treatment, 26 (31%) did not have any dose modification, 23 (26%) had dose reduction, while 36 (43%) had the dose increased to 180 mg/m2, at least for one cycle. The response rate in all eligible patients was 20% (95% confidence interval 13%-30%), 15% in group 1, 12% in group 2 and 27% in group 3. Patients with a cisplatin-free interval of > 12 months responded in 41%. The median duration of response was nine months (range 19 weeks to 3 years). Main toxicities were myelosuppression (leucopenia, neutropenia), nausea, vomiting, alopecia and mucositis. There were three cases of excessive toxicity leading to early discontinuation of HDE treatment and in one patient this contributed to death. No serious cardiotoxicity was recorded. CONCLUSIONS: It is concluded that HDE is active in platinum-pretreated patients with epithelial ovarian cancer and should be further studied in first-line in combination with paclitaxel and a platinum compound.

BACKGROUND: In vitro data demonstrated a dose-response relationship for doxorubicin in ovarian cancer (OC) cell lines. However, this dose-response question for doxorubicin was never carefully addressed in OC patients. These data and the more favorable toxicity profile of the anthracycline analogue epirubicin prompted us to study high-dose epirubicin (HDE) in relapsed OC patients. PATIENTS AND METHODS: This phase I study included 19 OC patients with measurable or evaluable disease and no more than one prior (cisplatin-containing) chemotherapy regimen. Dose escalation was not allowed in individual patients. Epirubicin was administered by rapid intravenous infusion (<5 min) once every 3 weeks and studied at the following dose levels: 120, 135, 150, 180 and 200 mg/m2 (at least 3 patients per dose level). None of the patients received hematopoietic growth factors. We defined the maximum tolerated dose (MTD) as the dose at which we observed WHO grade 4 hematologic toxicity in >/=50% and/or WHO grade 3 nonhematologic toxicity in >/=30% of the patients. RESULTS: The MTD was 200 mg/m2, with DLT being both hematologic (leukopenia and/or thrombocytopenia) and nonhematologic (mucositis). Objective responses were observed in 6 patients (response rate 32%), 3 of them occurring in 10 patients with primary platinum resistance. CONCLUSIONS: HDE is tolerable and has activity in second-line after cisplatin-based chemotherapy in OC patients. The recommended dose for phase II trials in such patients is 150 mg/m2, with escalation to 180 mg/m2 if toxicity permits.

AIM: Although the relationship between the dose delivered to adjacent organs (urinary bladder and rectum) and the frequency and severity of treatment complications has been reported in many series, the factors influencing pelvic dose distribution are not well defined. The aim of the study was to assess retrospectively the influence of the size of cervical cancer brachytherapy applicators (ovoids and uterine tandems) on pelvic dose distribution and the impact of various therapy-dependent factors on patient anatomy and on dose distribution in particular applications. PATIENTS AND METHOD: The subject of this study were 356 cervical cancer patients treated with Selectron LDR as a part of their radical radiotherapy. Analysed factors included preceding external beam radiotherapy (EBRT) or brachytherapy applications, use of general anaesthesia for application and the system of pellet loading. RESULTS: Significant correlation was found between the size of applicators and doses to bladder, rectum and points B: larger vaginal applicators produced lower dose in bladder and rectum and higher dose in point B (all p < 0.0001), longer uterine tandems produced lower dose in rectum and higher dose in point B (both p < 0.0001). Significant decrease in the frequency of use of large applicators (ovoids: p < 0.0001, tandems: p = 0.055) and worsening of dose distribution, i.e. higher doses to critical organs (respectively: bladder p = 0.0012, rectum p = 0.02) and lower point B dose (p = 0.0001) were observed at consecutive brachytherapy applications. Similar situation occurred in patients, who received EBRT prior to brachytherapy (ovoids: p < 0.001, tandem: p = 0.04, bladder dose: p = 0.009, rectal dose: p = 0.073, point B dose: p = 0.059). Vaginal applicators were larger (p = 0.026) and the dose distribution was better (bladder: p = 0.023, rectum: p = 0.002, point B: p = 0.0001) in patients who had their insertions performed under general anaesthesia. The comparison of 2 consecutively used systems of pellet loading revealed more favourable dose distribution: lower dose for bladder (p = 0.014) and higher dose for point B (p < 0.0001) for the system, which utilised more sources in ovoids and in the distal part of the uterine tandem, in spite of more frequent use of smaller applicators in this group of patients. In multivariate analysis ovoid size was related to preceding external beam radiotherapy (p = 0.025). Uterine tandem length was dependent on the number of preceding intracavitary applications (p < 0.001) and preceding external beam radiotherapy (p = 0.007). Bladder dose was related to preceding brachytherapy (p = 0.011) and the pattern of pellet loading (p = 0.031). Rectal dose was dependent only on the use of general anaesthesia during application (p = 0.001) and point B dose was dependent on the pattern of pellet loading (p < 0.001) and marginally-on the use of preceding external beam radiotherapy (p = 0.06). CONCLUSIONS: The results of this study allow for identification of treatment-related factors determining pelvic dose distribution in cervical cancer brachytherapy and may potentially enable optimisation of this distribution in particular clinical situation.

PURPOSE: The aim of this study was to assess retrospectively the influence of the size of cervical cancer brachytherapy applicators (ovoids and uterine tandems) on pelvic dose distribution and to analyze the impact of various patient- and disease-related factors on applicators' geometry and on dose distribution in particular applications. METHODS AND MATERIALS: The subject of this study were 356 cervical cancer patients treated with Selectron LDR as a part of their radical radiotherapy. Analyzed factors included patient age, weight, number of vaginal deliveries, and disease stage. RESULTS: The use of larger vaginal applicators resulted in lower bladder and rectum doses and in higher point B doses (all p < 0.0001); longer uterine tandems produced lower rectum doses and higher point B doses (both p < 0.0001). Increasing patient age and disease stage resulted in a decreased frequency of use of large ovoids (both p < 0.0001) and of long tandems (age: p = 0.0069, stage: p = 0.004). As a result, higher doses to bladder (age: p < 0.0001, stage: p = 0.017) and rectum (age: p = 0.037, stage: p = 0.011) were observed. Increasing age also resulted in lower point B doses (p < 0.0001). Increasing patient weight correlated with less frequent use of long tandems (p = 0.0015) and with higher bladder doses (p = 0.04). Higher number of vaginal deliveries was related to the increase in the use of long tandems (p = 0.002); in patients who had had at least one vaginal delivery, point B doses were significantly higher (p = 0.0059). In multivariate analysis ovoid size and uterine tandem length were dependent on patient age (respectively: p < 0.001 and p = 0.001), disease stage (respectively: p = 0.003 and p = 0.008) and on the number of vaginal deliveries (respectively: p = 0.07 and p = 0.008). Doses to critical organs and to points B were dependent on patient age (respectively: p < 0.001, p = 0.011, and p < 0.001) and on disease stage (respectively: p < 0.001, p = 0.004, and p = 0.048). CONCLUSION: The results of this study allow for identification of some patient- and disease-related factors influencing pelvic dose distribution in cervical cancer brachytherapy. This potentially may enable optimization of the dose distribution in particular clinical situations.

BACKGROUND: Due to rarity of fallopian tube cancer most series on this tumor are small and many problems have remained unsolved. The aim of this report is to review our experience with this neoplasm and to compare it with previously published data. METHODS: Retrospective study of 26 patients with fallopian tube cancer treated in one institution between 1974 and 1994. All patients underwent primary surgical treatment and 18 received adjuvant therapy including pelvic irradiation in 14 cases and chemotherapy in four. RESULTS: Relapse occurred in 18 out of 25 followed up patients. Upper abdominal component of relapse was encountered in 12 patients (67%), pelvic component - in eight (44%) and extraperitoneal component - six (33%). Pelvic relapse occurred in two out of 13 followed up patients treated with postoperative irradiation and in six out of 12 who did not receive postoperative radiotherapy. Survival ranged from 6 to 218+ months (median 23 months). Five-year actual survival was 33%. There were no 2-year survivors in patients presenting with stage II-IV disease. No correlation was found between tumor grade and survival. CONCLUSIONS: Fallopian tube cancer is a treatable disease but cure can be only achieved in patients with early tumor. Postoperative radiotherapy may result in better local control but does not preclude extrapelvic dissemination, therefore adjuvant chemotherapy should be considered in high risk patients. Registration of all new cases as well as prospective multicenter studies are warranted to establish optimal management.

Records of 42 patients with a diagnosis of uterine sarcoma treated between 1974 and 1995 at the Department of Oncology and Radiotherapy, Medical University of Gdansk have been reviewed. There were 15 cases of leiomyosarcoma, 14 cases of carcinosarcoma (malignant mixed mesodermal tumor) and 13 cases of endometrial stromal sarcoma. There were 24 FIGO stage I patients, 3 stage II patients, 7 stage III patients and 8 stage IV patients. Thirty seven patients had previously been operated on, of whom 33 had undergone total abdominal hysterectomy and bilateral salpingoophorectomy. Adjuvant postoperative treatment was administered in 19 patients and included radiotherapy in 16 patients, chemotherapy in two and chemotherapy and irradiation in one. Out of 31 radically operated patients, 19 (61%) had recurrences, within 2-42 months of primary treatment (median 10 months); nine patients had distant metasases, six patients had local recurrence and four had both local and distant failure. Treatment failure occurred in seven out of 14 patients who received adjuvant radiotherapy and in 12 out of 17 treated without irradiation. Median survival time in both groups was 26 months. The survival for the whole series ranged from 2 months to 19+ years (median 26 months) and was not related to tumor type. Two and five year actuarial survival rates were 54% and 30%, respectively.

BACKGROUND: Although the value of primary cytoreductive surgery for epithelial ovarian cancer is beyond doubt, the value of debulking surgery after induction chemotherapy has not yet been defined. In this randomized study we investigated the effect on survival of debulking surgery. METHODS: Eligible patients had residual lesions measuring more than 1 cm in diameter after primary surgery. After three cycles of cyclophosphamide and cisplatin, these patients were randomly assigned to undergo either debulking surgery or no surgery, followed by further cycles of cyclophosphamide and cisplatin. The study end points were progression-free and overall survival. At surgery 65 percent of the patients had lesions measuring more than 1 cm. In 45 percent of this group, the lesions were reduced surgically to less than 1 cm. RESULTS: Of the 319 patients who underwent randomization, 278 could be evaluated (140 patients who underwent surgery and 138 patients who did not). Progression-free and overall survival were both significantly longer in the group that underwent surgery (P = 0.01). The difference in median survival was six months. The survival rate at two years was 56 percent for the group that underwent surgery and 46 percent for the group that did not. In the multivariate analysis, debulking surgery was an independent prognostic factor (P = 0.012). Overall, after adjustment for all other prognostic factors, surgery reduced the risk of death by 33 percent (95 percent confidence interval, 10 to 50 percent; P = 0.008). Surgery was not associated with death or severe morbidity. CONCLUSIONS: Debulking surgery significantly lengthened progression-free and overall survival. The risk of death was reduced by one third, after adjustment for a variety of prognostic factors.

To evaluate the value of serum CA 125 antigen in monitoring of treatment of ovarian carcinoma, serum levels of this marker were monthly assayed during treatment and follow-up period in a group of 112 patients. CA 125 levels decreased in all 67 patients with remission. In a group of 41 patients with progressive disease, in 38 (93%) CA 125 levels increased, and in 3 (7%) - remained elevated. CA 125 became negative in all patients with clinical complete remission, although in 14 (38%) patients in this group second-look laparotomy revealed microscopic disease. In 12 of 15 patients with complete pathologic remission the increase of CA 125 preceded (2 to 58 weeks, median - 12 weeks) the recurrence of the disease. Time to progression depended on the increase rate of the antigen level.

BACKGROUND: A dose-response relationship for doxorubicin in ovarian cancer (OC) cell lines has been demonstrated in vitro. However, this has never been carefully addressed in the clinic. These data and the more favourable toxicity profile of the anthracycline analogue epirubicin were reasons to study high-dose epirubicin (HDE) in OC patients who relapsed on/after platinum-based chemotherapy. This was done both in a phase I/II feasibility study (n = 27; HDE dose 120-200 mg/m2 q3 weeks) and a still ongoing straightforward phase II study (n = 91; HDE dose 150-180 mg/m2 q 3 weeks). RESULTS: Responses were observed at all dose levels. Overall 24 of the 118 patients responded (20%), which is much higher than reported with lower doses (7% with doses of 60-110 mg/m2). The most important side effects were myelosuppression, alopecia, nausea and vomiting and mucositis. CONCLUSION: HDE is tolerable and has activity in second-line after platinum-based chemotherapy in OC patients.

The authors present the results obtained by Co60 radiotherapy in 110 patients with the diagnosis of primary brain tumour, including 73 adults and 37 children aged up to 15 years. The follow-up time was from 2 to 8 years and it was survived by 40 patients (36.4%). Among 70 dying patients in 61 cases (87.1%) death occurred within two years after the treatment, which showed that therapeutic failures developed early in these cases. The 5-year survival rate was 24.4%. The best results were obtained in cases of astrocytoma, and the prognosis was better in children.
