Adjuvant cisplatin-based chemotherapy for stage I and II ovarian cancer: a 7-year experience.

87 patients with high risk of recurrence FIGO stage I and II ovarian carcinoma were treated with adjuvant chemotherapy consisting of cisplatin 50 mg/m2 plus cyclophosphamide 600 mg/m2 on day 1 every 28 days for 6 courses. Toxicity and efficacy of the regimen was evaluated after a median follow-up of 45 months. Treatment-related toxicity was mild and reversible, consisting chiefly of acute WHO grade 2 myelosuppression (10% of patients) and controllable grade 3 emesis (55%). No late toxicity was observed. Actuarial 7-year survival and relapse-free survival (RFS) were 76% and 61%, respectively; a statistically significant difference in outcome was observed for undifferentiated grade tumour (G1 vs. G2 vs. G3: P less than 0.01) but not for FIGO stage disease (stage I vs. stage II). In our opinion, short-term chemotherapy including the most active single agent, i.e. cisplatin, appears a tolerable and effective treatment which deserves further evaluation in large randomised trials.

Carboplatin, doxorubicin, and cyclophosphamide versus cisplatin, doxorubicin, and cyclophosphamide: a randomized trial in stage III-IV epithelial ovarian carcinoma.

One hundred sixty-four patients with stage III-IV epithelial ovarian carcinoma were randomized to receive cisplatin (CDDP) 50 mg/mq, doxorubicin 45 mg/mq, and cyclophosphamide 600 mg/mq (PAC) or carboplatin 200 mg/mq, doxorubicin 45 mg/m2, and cyclophosphamide 600 mg/mq (CAC). To administer equitoxic doses at each cycle, the drug dosages were adjusted according to the hematologic toxicities experienced after the previous course; 44.7% of CAC and 21.1% of PAC patients required a dosage reduction at the second course (P = .002). Neither CAC nor PAC caused any clinically relevant neuro-nephrotoxicity; however, CDDP was administered with hydration and forced diuresis, while carboplatin was administered by rapid intravenous (IV) infusion. After six cycles, response rates were superimposable: 62.5% and 66.6% for CAC and PAC, respectively; pathologic complete responses (pCRs) were 16.7% for CAC and 23.2% for PAC; among patients with more than 2 cm residual disease, PAC induced more pCRs than CAC (eight of 52 or 15.4% v one of 42 or 2.4%, P = .07). Median survivals and progression-free survivals (PFSs) were 22.6 and 13.2 months for PAC, and 23.1 and 15.5 months for CAC, respectively; these differences are not significant. In conclusion, this trial demonstrates that equitoxic doses of PAC or CAC result in a similar response rate, PFS, and survival.

Histochemical study of mucinous ovarian cystomas of intestinal and mixed types: O-acetylated sialomucin content in relation to biologic behavior.

The subgroup of mucinous ovarian cystomas of intestinal type containing site 8 O-acetylated sialomucins and its relation to malignant behavior were studied. Of 75 mucinous cystomas of the ovary from the files of the Institute of Pathological Anatomy and Histology (University of Genoa), 54 were endocervical, 19 were mixed, and 2 were intestinal. As regards their histologic pattern, the 54 mucinous endocervical cystomas were benign, whereas the 19 mixed type group included 8 benign, 5 borderline and 6 malignant; the 2 intestinal type tumors were borderline. According to histochemical investigations, the frequency of tumors with goblet cells containing site 8 O-acetylated sialomucins (positive to PB/KOH/PAS) was 47% in the mixed type cystomas and 100% in the intestinal type cystomas. Twenty-five percent of benign mixed cystomas, 60% of borderline mixed cystomas, and 67% of mixed cystadenocarcinomas were positive to PB/KOH/PAS. One hundred percent of the borderline cystomas of intestinal type were positive. Our results confirm that among mucinous ovarian cystomas, those containing intestinal type epithelium are the most likely to fall within the borderline or malignant categories. Moreover, of all ovarian cystomas of intestinal type, those characterized by site 8 O-acetylated sialomucins seem to be more aggressive and, in general, to have a more malignant behavior than the mucinous cystic tumors of müllerian or endocervical type.

Intraperitoneal cytosine arabinoside administered in sequence with systemic cisplatin, doxorubicin, and cyclophosphamide in advanced ovarian cancer.

After standard management of stage III-IV ovarian cancer patients by surgical reduction of tumor mass and subsequent cisplatin-based combination chemotherapy, eradication of residual intraabdominal disease remains a major clinical problem. In an effort to increase response to therapy without adding marrow toxicity, after laparotomy, 21 stage III-IV ovarian cancer patients were treated with systemic chemotherapy comprising cisplatin, doxorubicin, and cyclophosphamide (PAC) on Day 1 followed by intraperitoneal (ip) cytosine arabinoside (Ara-C) on either Day 8 or 14, every 28 days. Ara-C, an S-phase-specific drug, was administered ip to exploit the pharmacologic advantage of an ip regimen at a time when a possible PAC-induced recruitment of cells into the proliferative pool could further maximize cell kill. Kinetic features of ovarian neoplastic cells recovered from peritoneal washings were monitored during treatment by measurement of the thymidine labeling index (TLI): data from four patients indicate that there is an increase in proliferating cells on Days 8 and 14 after PAC treatment. Toxicity of treatment was acceptable. Although 95% of evaluable patients had more than 2 cm of residual disease, response was observed in 47% of patients. The therapeutic potential of this regimen should be tested in patients with small-volume disease after debulking surgery.

Ultrasound examination in ovarian cancer patients. A comparison with second look laparotomy.

A series of 129 patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IV ovarian cancer, were evaluated with ultrasound examination and second look surgery. Results of both modalities were correlated in order to assess the reliability of ultrasound in detecting residual disease. After six cycles of chemotherapy, ultrasound was negative in 94 patients and positive in 35 patients. At second look, 57 patients were in complete pathologic remission, 16 had microscopic residual disease, 23 had macroscopic disease less than 2 cm, and 33 had macroscopic disease greater than 2 cm. Correlating ultrasonography and laparotomy, high correlations were seen in patients with no residual disease (92.2%); on the other hand, ultrasound examinations exhibited poor sensitivity and specificity in patients with microscopic disease (6.2%) and residual disease less than 2 cm (8.6%). Using ultrasound discrimination among patients with no residual disease, microscopic disease, or macroscopic disease less than 2 cm does not appear possible. Our suggestion is that ultrasound is not able to replace second look laparotomy in the detection of minimal residual disease in ovarian cancer patients.

Cisplatin and 5-fluorouracil in advanced and recurrent cervical cancer.

Nineteen consecutive patients with advanced or recurrent cervical cancer were treated with cisplatin 20 mg/m2 plus 5-fluorouracil 200 mg/m2 on days 1-5 every 3 weeks. Toxicity was acceptable and manageable, with most patients treated on an outpatient basis. The most important side effect was dose-cumulative neurotoxicity. In 18 evaluable patients a 61% objective response rate (1 complete and 10 partial) was achieved. In recurrent disease the regimen was effective both in irradiated lesions and in non-irradiated ones. Two out of five patients not previously treated with radiotherapy and/or chemotherapy responded to the treatment but tumor regression was insufficient for the disease to be controlled radically by subsequent surgery or radiotherapy. The median duration of response was 11 months (3-23) and the actuarial survival rate after 36 months follow-up was 43.3%.

Carboplatin (JM 8), adriamycin and cyclophosphamide (JAC) in advanced ovarian carcinoma: a pilot study.

Eleven untreated patients with advanced ovarian cancer were studied for tolerance and response to combination treatment with fixed doses of adriamycin (45 mg/m2) and cyclophosphamide (600 mg/m2) + escalating doses of carboplatin. At the first dose level of carboplatin (200 mg/m2), toxicity was acceptable. With carboplatin at 300 mg/m2, severe hematologic toxicity was observed. The dose-limiting toxicity was leukopenia. Although carboplatin was administered without any hydration, no patient experienced renal toxicity. Eight objective responses were observed in 9 clinically evaluable patients. At second look surgery, 3 complete responses and 4 partial responses were documented. Polychemotherapy with JAC (carboplatin, 200 mg/m2, adriamycin, 45 mg/m2, and cyclophosphamide, 600 mg/m2) is administrable with acceptable toxicity.

Uterine sarcomas: a clinicopathologic study.

A series of 48 cases with initial diagnosis of uterine sarcoma was reviewed to evaluate the validity of histologic criteria. The influence of pathologic and clinical prognostic factors and treatment modalities were examinated. The 32 patients included in this retrospective study after pathologic review had 5-year overall survival rate of 13.1%. Surgical pathological staging was demonstrated to be a significant prognostic factor, since patients with FIGO stage I-II disease had 33.5% actuarial survival rate whereas no patient with stage III-IV disease was alive at 37 months. Histological type, age and menopausal status did not significantly influence survival. Presence of heterologous elements and lymphovascular invasion were associated with a poor prognosis in the subgroup of patients with mixed mesodermal tumors. Median survival for patients receiving adjuvant treatment was 25 months compared to 19 months for those undergoing no adjuvant therapy.

Ultrasonic evaluation of cervical incompetence.

Ultrasound can provide important information for the assessment of cervical incompetence (C.I.) and for the follow-up of pregnant women submitted to a cervical cerclage. Attention must be paid to the technical problems involved in the examination and the physiological variations in anatomical configuration must be taken into account.

Evaluation of the cochleovestibular function in patients treated with carboplatin for ovarian carcinoma.

Carboplatin (JM8), a new cisdiamminodichloroplatin (CDDP) analogue, has exhibited the same antitumor as CDDP. In our pilot study, aiming at optimizing the dosage of this drug in a combination regimen with other chemotherapics, we planned to evaluate the existence of drug related damage on cochleo-vestibular structures. The study was performed on 9 patients suffering from advanced ovarian carcinoma. The results obtained in our study showed that patients undergoing carboplatin chemotherapy do not require an audiometric check-up. In order to assess definitely the existence of vestibular toxicity of this drug, larger studies planned to test JM8 in a high-dosage regimen are desirable.

The effect of lisuride hydrogen maleate in the hyperprolactinaemia-amenorrhoea syndrome: clinical and hormonal responses.

Eleven women with secondary amenorrhoea and hyperprolactinaemia were treated with lisuride, a new semisynthetic ergot derivative. Acute administration of lisuride (100 microgram orally) significantly suppressed serum prolactin (PRL) levels in nine out of eleven subjects. In these nine patients, prolonged treatment with lisuride (50--200 microgram daily) lowered PRL levels into the normal range, menstrual cycles were resumed and eight patients ovulated. Two patients, in whom lisuride failed to lower PRL levels into the normal range, did not resume normal menstruation. These data demonstrate that lisuride may be used clinically to lower PRL levels and to restore cyclic gonadotrophin secretion and ovulation in amenorrhoeic patients with hyperprolactinaemia.

Histological and ultrastructural changes of the endometrium in women using inert and copper-coiled IUDs.

The authors examined biopsy material obtained from women wearing inert and copper-coiled IUDs, under the light and electron microscopes. Examination of this material leads to the conclusion that there are no specific lesion attributable to either type of IUD. It can also be said that lesions characteristic for an inflammatory reaction prevail over all other possible endometrial changes.

Morphologic and biologic studies on ten cases of verrucous carcinoma of the vulva supporting the theory of a discrete clinico-pathologic entity.

Ten cases of verrucous carcinoma (VC) of the vulva diagnosed from January 1989 to December 1996 were studied. Patient age ranged from 50 to 83 years. The following examinations were performed on buffered formalin-fixed material: 1). in situ DNA hybridization, probes HPV 6/11, 16/18, 31/35/51; and 2). a series of immunohistochemical stainings to demonstrate wild and mutant types of the p53 protein, cytokeratin expression and pattern distribution (AE1 and AE3), and proliferating pattern (MIB 1). In situ DNA hybridization analysis for human papillomavirus 6/11, 16/18, 31/35/51 was negative in all cases. Wild and mutant types of p53 protein transcribed from related oncosuppressor gene were not detected. Keratins AE1 and AE3 showed a peculiar distribution pattern, that is, AE1 was uniformly positive in the surface and intermediate layers, while it was almost negative in the basal layer which-on the contrary-was mainly positive to AE3 keratins. MIB-1 highlighted 10-40% of proliferating cells; however, in all cases, 70-80% of MIB-1 positivity was found in the basal layer of the neoplastic epithelium. These results seem to show the morphofunctional and growth characteristics of neoplastic epithelium, thus stressing that VC should be considered as a discrete entity in vulvar tumors.

Salvage chemotherapy with paclitaxel in platinum-resistant advanced ovarian cancer patients.

Encouraging results with Paclitaxel are reported in ovarian cancer patients relapsing and progressing after platinum-based chemotherapy; however, the two populations have different probabilities of a response to a second-line treatment. Here we report the results achieved in 39 patients with platinum-refractory ovarian cancer, treated with Paclitaxel 175 mg/qm2 (or 135 mg/m2 if heavily pretreated) using 3-hour intravenous infusion every 3 weeks, in an attempt to verify the activity of this drug in platinum-resistant patients. The toxicity was mild to moderate and primarily hematologic and neurologic. The objective response rate is 12.8% with no complete responses. The response duration was brief and the median survival 6 (range 1-17) months. An accurate cost-benefit balance is necessary before routinely use of Paclitaxel in platinum-refractory patients. Further research is needed to determine the optimal role of Paclitaxel in the whole therapeutic strategy for ovarian cancer.
