Serum CYFRA 21-1 assay in squamous cell carcinoma of the cervix.

Squamous cell carcinoma antigen (SCC) is the best known marker for squamous cell carcinoma of the cervix as well as of the lung, oesophagus, head and neck and anal canal. Elevated levels of cytokeratin 19-fragments (CYFRA 21-1) have recently been detected in a large proportion of patients with non small cell cancer of the lung, and in particular of those with squamous cell carcinoma. Serum levels of CYFRA 21-1 (cut-off = 1.06 ng/mL) and SCC (cut-off = 2 ng/mL) were measured in blood samples collected before treatment from 15 patients with cervical intraepithelial neoplasia (CIN), 56 patients with cervical cancer, 48 patients with endometrial cancer, and 361 patients with benign uterine diseases. Serum CYFRA 21-1 values in patients with CIN were superimposable on those detected in patients with benign uterine diseases. Conversely, serum CYFRA 21-1 levels were higher in patients with cervical cancer (p < 0.05) and in patients with endometrial cancer (p < 0.05) than in those with benign uterine diseases. There was no significant difference in serum CYFRA 21-1 levels between cervical and endometrial cancer, and, as regards cervical cancer, there was no significant difference in antigen values between squamous cell carcinoma and adenocarcinoma. Among patients with squamous cell carcinoma of the cervix, CYFRA 21-1 values correlated with FIGO stage (stage IIb-IV vs stage Ib-IIa, p = 0.0303). Elevated CYFRA 21-1 levels were found in 20.0% of patients with CIN, in 41.7% of patients with squamous cell carcinoma of the cervix, in 62.5% of patients with adenocarcinoma of the cervix, in 45.8% of patients with endometrial cancer, and in 13% of patients with benign uterine diseases. Serum SCC was more sensitive than serum CYFRA 21-1 for both early and advanced squamous cell carcinoma of the cervix; these preliminary data seem to show that serum CYFRA 21-1 is of limited value for the management of patients with this malignancy.

Determination of serum levels of different cytokeratins in patients with uterine malignancies.

Tissue polypeptide antigen (TPA), TPS, Cyfra 21-1, Cytokeratins 8-18 (CTKRS 8-18), SCC and CA 125 were measured in blood samples drawn at diagnosis from 43 patients with endometrial cancer, 47 with cervical cancer, 11 with cervical intraepithelial neoplasia (CIN), and 236 with benign uterine disease as controls. The cut-off values for all antigens were chosen at the 95th percentile of the standard Gaussian variate of controls; these limits were 98 U/L for TPA, 127 U/L for TPS, 1.6 ng/mL for Cyfra 21-1, 1.2 ng/mL for CTKRS 8-18, 48 U/mL for CA 125, and 2.8 ng/mL for SCC. TPA had the same sensitivity as SCC for squamous cell carcinoma of the cervix (42%) and a higher sensitivity than CA 125 for endometrial cancer (40% vs 12% respectively). TPA was more sensitive than TPS for both cervical (40% vs 13%) and endometrial cancer (40% vs 21%). TPA and SCC had a higher sensitivity than Cyfra 21-1 (34%) and CTKRS 8-18 (27%) for squamous cell carcinoma of the cervix. In conclusion, as for soluble cytokeratin fragments, the serum TPA seems to be the most reliable marker for the management of cervical and endometrial cancer.

Recurrence patterns in patients with early stage cervical cancer treated with radical hysterectomy and external pelvic irradiation.

One hundred and fifty patients with clinical FIGO stage IB-II cervical cancer who underwent radical surgery followed by external pelvic irradiation between 1978 and 1991 were reviewed. Until June 1994, 28 (18.7%) patients developed recurrent disease. Seventeen (60.7%) of them experienced a pelvic failure, 7 (25.0%) an extrapelvic failure and 4 (14.3%) both a pelvic and an extrapelvic failure. The median time to recurrence was 16 months for patients with pelvic failure (range = 4-50 months), 27 months for those with extrapelvic failure (range = 6-49 months), and 21 months for those with both pelvic and extrapelvic failure (range u 8-56 months). Recurrence rates were significantly related to surgical-pathologic stage, tumor size and lymph node status, but not to histologic type. An extrapelvic recurrence, alone or associated with a pelvic failure, was found in 0.9% of 117 patients with negative lymph nodes, 6.2% of 16 patients with one or two positive lymph nodes, and 52.9% of 17 patients with three or more positive lymph nodes, (p = 0.0001). It is worth noting that 9 (81.8%) out of the 11 patients who developed extrapelvic recurrences had three or more involved lymph nodes. The number of positive lymph nodes (p = 0.0001) and the tumor size (p = 0.0046) were independent prognostic variables for disease-free survival.

Analysis of treatment failures in patients with early-stage uterine leiomyosarcoma.

This retrospective study aimed to investigate the treatment failures in 26 patients with stages I-II uterine leiomyosarcoma (> or = 10 mitoses per 10 high-power field (HPF) who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy +/- adjuvant external pelvic irradiation. Thirteen (50%) patients developed recurrent disease, after a median time of 10 months from surgery (range = 4-72 months). Recurrence was pelvic in 3 (23%) patients, extrapelvic in 9 (69%) patients, and both pelvic and extrapelvic in 1 (8%) patient. Disease-free survival was better for premenopausal than for postmenopausal patients (p = 0.002) and for patients with < 20 mitoses per 10 HPF than for those with > or = 20 mitoses per 10 HPF (p = 0.006). In conclusion, patients with early-stage disease who had undergone locoregional treatment experienced a high recurrence rate. Most of the treatment failures were extrapelvic. Multicentric randomized trials on the role of adjuvant chemotherapy are advocated.

Serum interleukin-6 levels in uterine malignancies. Preliminary data.

Interleukin-6 (IL-6) was measured with an enzyme-immunoassay in blood samples drawn at diagnosis from 37 patients with endometrial cancer, 36 with cervical cancer, 9 with cervical intraepithelial neoplasia (CIN) and 68 with benign uterine disease. The minimal detectable dose of IL-6 was 3 pg/mL. Detectable serum IL-6 levels were found in 9% of patients with benign uterine diseases, 11% of patients with CIN, 44% of patients with cervical cancer and 11% of patients with endometrial cancer. As regards cervical cancer, serum IL-6 levels > 3 pg/mL were found in 36.0% of 25 patients with stage Ib-IIa disease and in 64% of 11 patients with stage IIb-IV disease. As regards endometrial cancer, serum detectable IL-6 levels were observed in 0% of 30 patients with stage I-II disease and in 57% of 7 patients with stage III-IV disease (p = 0.0005). These preliminary data suggest that IL-6 may be involved in the progression of uterine malignancies.

Preoperative serum intercellular adhesion molecule-1 (ICAM-1) and E-selectin (endothelial cell leukocyte adhesion molecule, ELAM-1) in patients with epithelial ovarian cancer.

The serum levels of intercellular adhesion molecule-1 (ICAM-1) and E-Selectin (endothelial cell leukocyte adhesion molecule, ELAM-1) were retrospectively measured in serum samples drawn at diagnosis from 66 patients with epithelial ovarian cancer and 128 patients with benign ovarian masses. The preoperative serum ICAM-1 levels were higher in the former group (p < 0.0001), while serum E-Selectin concentrations were similar in the two groups (p = NS). Among patients with epithelial ovarian cancer, neither serum ICAM-1 nor E-selectin levels correlated with FIGO stage and with histologic type. The serum assay of ICAM-1 and E-Selectin seems to have limited value in the management of patients with epithelial ovarian cancer.

The measurement of plasma D-dimer (DD) levels in the follow-up of patients with ovarian cancer.

Peripheral blood samples for the measurement of DD and CA 125 were drawn from 39 patients with ovarian cancer at different times from first surgery. Both median DD and CA 125 levels were significantly higher in the 20 samples drawn from patients with clinically evident disease than in the 37 samples from patients without clinical evidence of disease (477 vs 300 ng/ml p = 0.006, and 66 vs 11 U/ml, p < 0.0001, respectively). DD levels did not correlate with CA 125 levels. The sensitivity, specificity and diagnostic accuracy of the tests in the assessment of clinical disease status were as follows: 65%, 62% and 63% for DD (cut-off = 416 ng/ml); 70%, 92% and 84% for CA 125 (cut-off = 35 U/ml); 90%, 59% and 70% for DD "or" CA 125; and 45%, 95% and 77% for DD "and" CA 125. DD levels correlated with the clinical course of disease in ovarian cancer patients. However, the concomitant determination of DD and CA 125 did not improve the reliability of CA 125 assay alone in the follow-up of these patients.

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.
