Replacement therapy for breast cancer survivors. A pilot study.

BACKGROUND: Traditionally, breast cancer survivors were not considered as candidates for hormone replacement therapy (HRT) because of the possibility that an occult metastatic site of disease might be activated, thus negatively influencing the outcome for the patient. METHODS: A retrospective review of 77 breast cancer survivors who have taken HRT was conducted. RESULTS: Seven recurrences were reported among the 77 patients studied in-depth, with correlations to stage, age, and node and receptor status. There have been no recurrences among the 33 additional patients who were placed on the study after the completion of this analysis. CONCLUSIONS: No significant adverse outcome was detected in this group of breast cancer survivors receiving HRT. Given the established benefits of HRT, a reappraisal of this subject is necessary, and a prospective randomized trial is essential.

The effect of debulking surgery after induction chemotherapy on the prognosis in advanced epithelial ovarian cancer. Gynecological Cancer Cooperative Group of the European Organization for Research and Treatment of Cancer.

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.

Adjuvant treatment for early epithelial ovarian cancer: results of two randomised clinical trials comparing cisplatin to no further treatment or chromic phosphate (32P). G.I.C.O.G.: Gruppo Interregionale Collaborativo in Ginecologia Oncologica.

BACKGROUND: From 1983 to 1990, 271 consecutive patients with stage I ovarian cancer entered two randomised trials, aimed at assessing the role of adjuvant chemotherapy after radical surgery in early stages of ovarian cancer. Trial I compared cisplatin (50 mg/m2 with repeated courses every 28 days for 6 cycles) to no further therapy in F.I.G.O. stage Ia & b Grade II-III patients; trial II compared cisplatin (same dose and schedule) to 32P in Iaii & bii and Ic patients. METHODS: Both studies were multicentric and centrally randomized. Treatment was allocated by phone and stratified by center. All patients satisfying major eligibility criteria (histological and grade, no previous neoplasms) were analysed according to treatment allocated by randomisation. RESULTS: With a median observation time of 76 months, cisplatin significantly reduced the relapse rate by 65% (HR = 0.35; 95% CI = 0.14-0.89, p = 0.028; Cox Model) in trial I and 61% (HR = 0.39; 95% CI = 0.19-0.77, p = 0.007; Cox Model) in trial II. Survival was not significantly different (trial I - Kaplan-Meier overall 5-year survival: cisplatin = 88%, control = 82%, HR = 1.15; 95% CI = 0.44-2.98; p = 0.773; Cox Model); trial II - overall 5-year survival: cisplatin = 81%, 32P = 79%, HR = 0.72; 95% CI = 0.37-1.43; p = 0.354; Cox model). In both studies the risk of dying after relapse increased for patients originally randomized to the cisplatin arms: in trial I, 6 of 7 patients in the cisplatin relapsed arm and died of tumor compared with 8 of 14 patients in the control arm. In trial II 11 of 12 patients on cisplatin, and 18 of 26 on 32P succumbed to tumor recurrence. CONCLUSION: Adjuvant cisplatin treatment in early ovarian cancer significantly prevents relapse in comparison to 32P in stage IC patients or to no immediate treatment in earlier stage women. The impact of cisplatin adjuvant treatment on survival remains, however, unclear.

Prospective multicenter study on CA 125 in postmenopausal pelvic masses.

The purpose of this study was to determine the diagnostic value of CA 125 in comparison with transabdominal ultrasound (US) in the evaluation of postmenopausal women with pelvic mass to detect malignant epithelial ovarian tumors. Postmenopausal patients with pelvic mass were studied with gynecologic examination, US and CA 125 determination. Three hundred eighty-eight patients were entered in the study. According to stratification based on US (probably benign, equivocal, possibly malignant) and CA 125 (< 35 U/ml, negative; between 35 and 65 U/ml, borderline; > 65 U/ml, positive), 290 patients were considered eligible for surgery. Specificity, sensitivity, positive and negative predictive value, and accuracy of US and CA 125 were calculated with respect to histological examination. Out of 290 operated patients, 134 had a benign ovarian pathology, 34 had extraovarian benign pathology, 106 had an ovarian malignancy, and 16 presented with an extraovarian malignant pathology. The results according to ovarian malignant pathology were as follows. CA 125 (> 65 U/ml): Specificity, 92.5%; sensitivity, 71.7%; accuracy, 83.3%. CA 125 (> 35 U/ml): Specificity, 82.0%; sensitivity, 78.3%; accuracy, 80.4%. US: Specificity, 77.6%; sensitivity, 84.9%; accuracy, 80.3%. Combination of US and CA 125 (> 65 U/ml): Specificity, 96.1%; sensitivity, 91.7%; accuracy, 94.3%. Determination of CA 125 is a highly specific method in predicting ovarian cancer in postmenopausal women with a pelvic mass. The association with US significantly improves the overall accuracy and may support therapeutical decision making by distinguishing between a significant percentage of women most likely to benefit from prompt intervention and women who may be managed following minor surgical diagnostic approach, such as fine-needle aspiration.

Follow-up after primary therapy: management of the symptomatic patient-surgery.

The benefit of secondary surgery in patients (pts) recurring after a negative second look is still a matter of controversy. Twenty-seven patients underwent this procedure: 5 were stage I at primary surgery and 22 stage IIIC. All 5 stage I pts had a pelvic recurrence: 3 were left with no visible tumor and were then treated with cisplatin chemotherapy. Two are alive and with no evidence of disease (NED) at 45 and 62 months. In stage IIIC pts, optimal debulking (< 2 cm) was achieved in 59% (13/22), and 8 of them had no macroscopic residual tumor. All pts were then treated with cisplatin chemotherapy. Only 3 pts are still alive and NED at 56, 61, and 67 months. The most important prognostic parameters regarding secondary surgery seem to be residual tumor volume both at primary and secondary surgery, time interval between negative second-look surgery and recurrence, histology (serous) and degree of differentiation, and response to second-line chemotherapy. Finally, surgery can have a true palliative role in pts who present with bowel obstruction; in our center, most patients who had a definitive procedure did benefit from the quality of life viewpoint.

Phase II study of high-dose megestrol acetate in patients with advanced ovarian carcinoma.

The EORTC Gynaecological Cancer Cooperative Group conducted a phase II study of high dose oral megestrol acetate: 800 mg/day for 1 month followed by 400 mg/day as maintenance treatment, in heavily pretreated patients with ovarian cancer. Of 72 patients included in this study, 54 were fully evaluable for response and toxicity. The response rate was low with only 1 patient having a partial response, 9 patients with stable disease and 44 patients with progressive disease. The toxicity profile was low. However, 1 patient died after 2 months of treatment, and in 3 patients thrombo-embolic events occurred. Weight gain varied in 20 of the 61 patients from 0.5 to 16 kg. This study does not suggest that the overall 10% benefit from hormonal therapy for chemotherapy refractory ovarian cancer will improve by increasing the dose.

Adjuvant therapy in stage-I epithelial ovarian cancer: an open question.

From January 1980 to December 1991, 137 patients suffering from Stage I EOC, were treated in our Institute. All patients underwent primary surgery with intensive staging procedures in 82% of cases; 12 patients underwent USO. Sixty-one out of 137 patients did not receive complementary treatment, 66 patients were treated with chemotherapy and 10 patients with i.p. P32. Three risk categories were identified, according to stage and grade: R1 = Stage IA-B G1 (45 cases); R2 = Stage IA-B G2-3 (31 stage); R3 = Stage IC all grades (53 cases). Forty out of 45 R1 cases did not receive adjuvant therapy; 12/31 R2 cases underwent surgical treatment only, 16/31 received adjuvant chemotherapy and 3/31 i.p. P32; 39/53 R3 patients were treated with chemotherapy and 6 with i.p. P32. Twenty-six patients (18.9%) suffered from a neoplastic relapse. Overall actuarial 5- and 10-year survival was: R1 = 96.3% and 89.9%; R2 = 79.6% and 79.6%; R3 = 79.2% and 62.3% respectively. There was no difference in survival between R2 treated and untreated patients, while difference emerged in R3 patients between chemotherapy and i.p. P32 groups. Five-year actuarial survival for the 26 patients suffering from recurrence was 40.5%.

Estro-progestinic replacement therapy modulates the levels of basic fibroblast growth factor (bFGF) in postmenopausal endometrium.

The levels of basic fibroblast growth factor (bFGF) in human endometrium do not vary during the ovulatory cycle but they increase significantly after menopause (M. Rusnati et al., Growth Factors, 3, 299-307, 1990). Here we report that cyclic estro-progestinic replacement therapy reduces the levels of bFGF in human postmenopausal endometrium to those measured in ovulatory cycle endometrium. Also, we have observed that the levels of bFGF in well-differentiated adenocarcinomas of the endometrium from postmenopausal patients are lower than those detected in their normal counterpart and are comparable to those measured in the normal cycling tissue. The data indicate that the stimulation of cell proliferation induced in postmenopausal endometrium by hormonal therapy or by neoplastic transformation is paralleled by a decrease of endometrial levels of bFGF. This may be due to an increase of the turnover rate of the growth factor in the proliferating versus the quiescent tissue and suggests a role of bFGF in the growth of normal and neoplastic human endometrium. Our data represent the first evidence that sex hormones modulate the levels of biologically active bFGF in vivo.

The impact of whole-abdomen radiotherapy on survival in advanced ovarian cancer patients with minimal residual disease after chemotherapy.

Between March 1982 and March 1987, 26 patients with minimal residual epithelial ovarian cancer after cisplatin-based chemotherapy were treated with whole-abdomen irradiation [moving-strip technique (MST)] with or without pelvic boost. Prior to radiation residual disease was macroscopic (less than or equal to 0.5 cm) in 8 cases and microscopic (positive random biopsies) in 18 cases (8 diffuse, 10 localized). Eighty percent of patients completed the planned therapy, 34% with interruptions secondary to hematologic or gastrointestinal toxicity. With a median follow-up time from completion of radiotherapy of 24 months, 34.6% of patients remain alive. The 3-year survival rates (from the second-look procedure) are 50% for the patients with microscopic tumor and 25% for those with macroscopic residual disease. Progression-free intervals are statistically different in the two groups: 16.9 months for microscopic residuals and 6.16 months for macroscopic tumors (P = 0.037). All but two of the recurrences were in the irradiated field (pelvis and/or abdomen); one was distant (pleural) and one only retroperitoneal. Small bowel injury was the most limiting complication: 3.8% was registered as fatal acute enteritis and 19% as late obstruction or malabsorption syndrome, necessitating surgical intervention in 10% of treated cases.

Basic fibroblast growth factor in ovulatory cycle and postmenopausal human endometrium.

Biopsies of human endometrium were studied for the presence of basic fibroblast growth factor (bFGF). An immunoreactive Mr 18,000 bFGF-like molecule was detected at high levels both in ovulatory cycle and postmenopausal endometrium. This molecule was identified as bFGF on the basis of its molecular weight, its affinity for heparin, its capacity to induce plasminogen activator production and cell proliferation in endothelial GM 7373 cells, and its cross-reactivity with various anti-bFGF antibodies. The levels of endometrial bFGF do not change during the menstrual cycle but they increase significantly after menopause, as evaluated both by biological and immunological assays. Lower levels of an acidic FGF-like activity were also evident in ovulatory cycle endometrium but, at variance with bFGF, no significant increase of this activity was observed in postmenopausal endometrium. These data represent the first characterization of a polypeptide growth factor present in human endometrium.

Randomized trial in advanced ovarian cancer comparing cisplatin and carboplatin.

The aim of this multicenter randomized trial was to compare carboplatin (400 mg/m2) and cisplatin (100 mg/m2) in patients with untreated advanced epithelial ovarian cancer. Toxicity and treatment efficacy assessed by pathological response rate, progression-free survival, and survival were the endpoints of the study. One hundred seventy-three patients with advanced epithelial ovarian cancer, F.I.G.O. (International Federation of Gynecology and Obstetrics) stage III and IV were accrued in the trial. The median follow-up time was 15 months (maximum, 34); three patients in each treatment arm were not eligible (four, nonepithelial ovarian cancer type; one, no data, and one, stage II). Patient characteristics were similar in the two groups. In the carboplatin-treatment arm, the overall pathological response rate was 57.3% and the complete pathological response rate was 26.8%. In the cisplatin-treatment arm, the overall pathological response rate was 71.6% and the complete pathological response rate was 24.7%. There was no statistical difference in the two arms in survival or progression-free survival. Cisplatin was more nephrotoxic while carboplatin induced a higher degree of myelosuppression, especially thrombocytopenia; however, severe hematological toxicity was seldom observed. Carboplatin is a cisplatin analog with definite activity in ovarian cancer, but it is more active than the parent compound. Because of less nonhematological toxicity, carboplatin is undoubtedly a useful substitute in patients who cannot be given cisplatin. Further experience is needed to indicate whether or not carboplatin should completely displace cisplatin in the clinical treatment of ovarian cancer.

Histological features of uteroplacental vessels in normal and hypertensive patients in relation to birthweight.

Placental bed biopsies were obtained during caesarean section from normal, pre-eclamptic and hypertensive pregnancies. Of the 14 biopsies from normal pregnancies 13 showed normal vascular physiological changes in the decidua and in the myometrium. Biopsies from 24 pregnancies complicated by pre-eclampsia showed acute atherosis in 18 and physiological changes limited to the decidua in six; none had normal physiological changes. Biopsies from five hypertensive patients showed all three types of histological changes. The mean birthweight centile was lower in the group with atherosis than in the group with limited and the group with normal physiological changes.

Ataxia-telangiectasia and endodermal sinus tumor of the ovary: report of a case.

Ataxia-telangiectasia, an inherited disorder characterized by progressive cerebellar ataxia and telangiectasias, is often associated with primary immunodeficiency and high incidence of malignancies, mostly of the lymphoreticular type. Endodermal sinus tumor is a rare germ cell tumor of the ovary characterized by an extremely rapid growth and poor prognosis. Both these diseases are associated with an abnormal production of alpha-fetoprotein. Primary tumors of the ovary in patients with ataxia-telangiectasia are extremely rare and the association of an endodermal sinus tumor and ataxia-telangiectasia has never been reported in the literature. This case report serves to focus on the particular problems encountered in the diagnosis and management of two diseases both characterized by the same serum marker.

Treatment of primary invasive cervical cancer. Considerations on 997 consecutive cases.

From 1965 to 1979 997 consecutive cervical cancer patients were treated at the University of Brescia. Stage I B and II A low risk patients underwent radical surgery, followed by Co60 external pelvic radiation when positive nodes and/or adverse pathological factors on the specimens were encountered. In stage I B the 5-year survival was 95.9% and 82.7% in the two groups and in stage II A 93.3% and 76.5% respectively. Bulky and large tumors were treated by intracavitary radium followed by radical hysterectomy and, if indicated, by Co60 external beam pelvic radiation. All other patients and all stage II B were treated by radiotherapy. The results of primary radical surgery may reflect the favourable preselection of cases. Postoperative radiation teletherapy in case of adverse pathological factors is of benefit to the patients.

Cisplatin, vinblastine, and bleomycin combination chemotherapy in endodermal sinus tumor of the ovary.

The combination of cisplatin, vinblastine, and bleomycin was administered to 13 previously untreated patients with pure endodermal sinus tumor of the ovary. Twelve had unilateral salpingo-oophorectomy as initial surgery. Among 11 women whose alpha-fetoprotein (AFP) levels returned to normal after cisplatin, vinblastine, and bleomycin therapy, nine are alive with no evidence of disease after periods of 20 months to six years and two months. In two patients, AFP levels returned to normal only after the introduction of different combination chemotherapies. Hematologic toxicity was moderate. Pulmonary toxicity due to bleomycin occurred in two cases. All menstruating patients resumed normal menstrual function after the interruption of chemotherapy. Two patients delivered normal term infants.
