Combined evaluation of serum CA 125 and CAM 29 in patients with epithelial ovarian cancer.

We examined 92 patients with epithelial ovarian cancer and 262 patients with benign ovarian diseases undergoing laparotomy. On the basis of a nonparametric method, antigen levels corresponding to prefixed 95% specificity values in a group of 674 women with benign gynecologic diseases were taken as cutoff limits (88.8 U/ml for CA 125 and 13.7 U/ml for CAM 29). Moreover, CA 125 and CAM 29 levels were measured serially during and after chemotherapy in 26 women selected from the patients with advanced epithelial ovarian cancer. At diagnosis, serum CA 125 was as sensitive as serum CAM 29 for nonmucinous tumors, but more sensitive than serum CAM 29 for mucinous tumors. The association of the two markers seemed to give no advantage over the CA 125 assay alone in the diagnosis of epithelial ovarian cancer. In monitoring the response to chemotherapy and follow-up of patients with epithelial ovarian cancer, changes in CA 125 levels correlated with the clinical course of disease better than changes in CAM 29 levels, and the serum CA 125 assay was more reliable than the serum CAM 29 assay in the early detection of tumor progression. In conclusion, serum CAM 29 did not seem to represent a complementary assay to serum CA 125 in the management of patients with epithelial ovarian cancer.

The influence of some prognostic factors on the clinical outcome of patients with squamous cell carcinoma of the vulva.

The present paper examined the influence of patient age, surgical T stage, tumor size, tumor differentiation and lymphnodal status on the clinical outcome of 29 patients with primary vulvar squamous cell carcinoma treated with radical surgery. Eighteen patients underwent radical vulvectomy with bilateral inguinal-femoral lymphadenectomy alone; 10 patients had additional bilateral pelvic lymphadenectomy; another patient had additional bilateral pelvic lymphadenectomy and anterior pelvic exenteration for a carcinoma of the clitoris involving the urethra. Nine patients developed relapsing disease; the site of recurrence was local in 4 patients, inguinal in 2, both local and inguinal in one patient, pelvic in one, both pelvic and distant in one. Eight recurrences occurred within 24 months from surgery; another patient developed an inguinal recurrence 45 months after operation. The actuarial 5-year disease-free survival rates were as follows: 64% for patients younger than 70 years and 63% for patients 70 years of age or older (p = not significant); 79% for patients with surgical T1-T2 stage disease and 30% for those with surgical T3 stage disease (p = 0.01); 88% for patients with tumor size less than 3 cm and 31% for those with tumor size greater than 3 cm (p less than 0.001); 66% for patients with well or moderately differentiated tumor and 51% for those with poorly differentiated tumor (p = not significant); 82% for patients with negative groin lymph nodes and 39% for those with positive groin lymph nodes (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

The potential of primary cytoreductive surgery in patients with FIGO stages III and IV ovarian carcinoma.

The present study included 40 patients with advanced ovarian carcinoma who underwent surgery and combination chemotherapy with cisplatin or carboplatin at the Department of Gynecology and Obstetrics of the University of Pisa. All the 20 optimally cytoreduced (residual disease lower than 2 cm) patients were clinically free of disease after the sixth course of chemotherapy; second-look laparotomy showed a pathological complete response (PCR) in 16 of them (80%). The 5-year actuarial progression- free and overall survival rates of this group of patients were 44.0% and 82.2% respectively. Among the 20 patients with residual disease greater than 2 cm after the first laparotomy, a clinical complete response was obtained in 3 (15%) and a clinical partial response in 12 (60%); a PCR was achieved in only 1 (5%) of them. The 5-year actuarial progression- free and overall survival rates of this group of patients were 0% and 14.2% respectively. The present paper confirms that surgery plays a major role in the treatment of ovarian carcinoma. Aggressive surgical removal with optimal tumor reduction can produce a favourable effect on patients survival time, since there is an inverse relationship between the volume of residual disease after the first laparotomy and the likelihood of response to chemotherapy.

Struma ovarii. Observations on three cases.

The true struma ovarii is a rare teratomatous neoplasia, composed with typical thyroid tissue. Generally it is asymptomatic or only determines a mild hypogastric weighting feeling. In a few subjects this neoplasm is secreting and rise to hyperthyroidism. The Authors describe the clinical and anatomopathological characteristics of 3 cases of true struma ovarii come to their observation. No malignant histologic features in any of them was seen. In the relatively short period of post surgical observations no women showed relapses or metastases. This confirms that true struma ovarii is usually a benign tumor.

Incidence of malignant ovarian neoplasms in the provinces of Pisa, Lucca, Livorno and La Spezia during the period 1976-1981.

The Authors report a critical review of all the cases of ovarian neoplasia observed in the provinces of Pisa, Livorno, Lucca and La Spezia between 1976 and 1981. This study does not take into account all the cases in which incomplete clinical and histologic data were available or the first histologic diagnosis was not confirmed by a second examination. The incidence rate and distribution characteristics of all the histologic types of ovarian neoplasia are described.

HPV testing and Pap test: role for a combined approach in a non-screened population.

The aim of the present study was to test the polymerase chain reaction (PCR) as a tool to identify human papillomavirus (HPV) in routine cytological samples scraped from the uterine cervix. Moreover, attention has been focused on the correlation between HPV types and early intraepithelial lesions. The study involved 586 women who had undergone conventional Pap test. Analysis of HPV infection was performed by PCR and HPV typing by dot blot. In a group of 78 cases histologically diagnosed as high-grade squamous intraepithelial lesions (HSILs), the cytological diagnosis was correct in 92.3% and the HPV test was positive in 89.8% of cases; combined positivity at Pap and/or HPV tests raised this figure to 99.0%. In a group of 67 cases histologically diagnosed as low-grade squamous intraepithelial lesions (LSILs), the cytological diagnosis was correct in 73.1% and the PCR-based HPV test was positive in 64.2%; combined positivity at Pap and/or HPV tests raised this figure to 91.0%. This study confirms the limitations of screening programs based on Pap test only. Our results suggest, in fact, that adding the HPV test to primary screening could increase the yield of preinvasive cervical lesions.

Serum levels of soluble receptors for tumor necrosis factor (p55 and p75 sTNFr) in endometrial cancer.

The pretreatment serum levels of the soluble receptors for tumor necrosis factor (p55 and p75 sTNFr) were retrospectively measured in 38 patients with endometrial cancer and 55 patients with benign uterine diseases as controls. Serum p55 and p75 sTNFr levels were significantly higher in patients with endometrial cancer (median = 2.4 ng/ml, range = 1.4-6.8 ng/ml, and median = 7.1 ng/ml, range = 2.5-19.5 ng/ml, respectively) than in controls (median = 1.7 ng/ml, range = 0.5-4.0 ng/ml, p < 0.0001, and median = 5.2 ng/ml, range = 2.6-21.9 ng/ml, p = 0.03, respectively). In the former, serum p55 and p75 sTNFr values correlated with the extent of disease (stage III-IV versus I-II: p = 0.04 and p = 0.03, respectively). Among the 23 patients with stage I endometrial cancer who underwent initial surgery, the preoperative serum levels of both receptors correlated with the histologic grade and myometrial invasion but not with the clinical outcome. In conclusion, a stage-dependent release of the soluble receptors for TNF into the bloodstream occurs in patients with endometrial cancer.
