Adenocarcinoma of the uterine cervix. Prognostic significance of pretreatment serum CA 125, squamous cell carcinoma antigen, and carcinoembryonic antigen levels in relation to clinical and histopathologic tumor characteristics

The prognostic value of the pretreatment serum CA 125, squamous cell carcinoma antigen (SCC), and carcinoembryonic antigen (CEA) levels in relation to tumor type, vascular invasion by tumor cells, and lymph node metastases was investigated in 77 patients with cervical adenocarcinoma. In Stage IB (International Federation of Gynecology and Obstetrics [FIGO]), the five-year actuarial survival of patients with pretreatment serum CA 125 levels greater than 16 U/ml was 52.4% versus 95.6% when normal serum CA 125 levels were determined (P less than 0.01). Pretreatment serum SCC or CEA levels had no substantial prognostic value. In Stage IB (FIGO), 42% of the patients with elevated serum CA 125 levels had lymph node metastases versus 4% when normal levels were found (P = 0.012). The presence of vascular invasion (P = 0.01) or lymph node metastases (P = 0.001) was associated with an increased risk for recurrent disease. Adenosquamous tumors showed a higher incidence of vascular invasion (P = 0.05) and a higher incidence of elevated serum CA 125 levels (P = 0.03). Particularly in Stage II, adenosquamous tumors were found to have a poorer prognosis than adenocarcinomas (P = 0.0566). We conclude that in cervical adenocarcinoma serum CA 125 is an important prognostic factor and an implicit indicator of tumor virulence.     

SCC antigen in the serum as an independent prognostic factor in operable squamous cell carcinoma of the cervix

The aim of this study was to retrospectively examine whether the occurrence of squamous cell carcinoma (SCC) antigen tumour marker in the serum has prognostic significance in operable SCC of the cervix at the International Federation of Gynaecology and Obstetrics (FIGO) stages IA2-IIB. A total of 129 patients who had undergone a radical hysterectomy for SCC of the uterine cervix at the Department of Gynecology of the Martin-Luther University, Halle-Wittenberg in 1991-2000 were included. SCC antigen (Ag) was measured by IMx SCC-Ag microparticle enzyme immunoassay (Abbott Laboratories, Abbott Park, IL, USA). To assess the prognostic value of SCC antigen in the serum, we used a step-by-step multivariate analysis based on the Cox proportional hazard regression model. Using a cut-off value of 3.0 ng/ml, we detected preoperative SCC antigen in the serum as an independent prognostic factor in SCC of the cervix, both for recurrence-free and overall survival (P=0.003 and 0.0078). In this retrospective analysis the value of the SCC antigen tumour marker correlates with prognosis in operable SCC of the cervix, independent of tumour size, pelvic nodal status, cervical stroma infiltration, parametrial spread and tumour grading.     

Clinical value of tumor markers for early detection of recurrence in patients with cervical adenocarcinoma and adenosquamous carcinoma.

OBJECTIVE: The clinical value of tumor markers for early detection of recurrence was investigated in 32 patients with cervical adenocarcinoma or adenosquamous carcinoma who had recurrent tumors. METHODS: Serum levels of CA 125, CA 19-9, carcinoembryonic antigen (CEA), and squamous cell carcinoma antigen (SCC), in addition to clinical status at the time of recurrence were investigated. RESULTS: Among the 32 patients, 26 had no symptoms at the time of recurrence. In 20 patients, elevated serum levels of tumor markers were the first sign of recurrence. In 21 patients with recurrent adenocarcinoma, the positive rates were 14% (CA 125), 62% (CA 19-9), 29% (CEA), and 5% (SCC). There were 71% of cases positive for CA 19-9 and/or CEA. In 11 patients with recurrent adenosquamous carcinoma, the corresponding positive rates were 37% (CA 125), 46% (CA 19-9), 64% (CEA), and 55% (SCC), with 100% positive for CA 19-9, CEA, and/or SCC. CONCLUSIONS: The combination of CA 19-9 and CEA is probably the most promising for detection of recurrent cervical adenocarcinoma. For adenosquamous carcinoma, the additional use of SCC is recommended.     

Experiences with SCC antigen,a new tumor marker for cervical carcinoma

Squamous cell carcinoma (SCC) antigen was first described by Kato et al. in patients with carcinoma of the cervix uteri. SCC serum levels can be measured with a radioimmunoassay. In our investigation, 2.0 ng/ml was taken as the upper limit of the standard range.In 35 healthy women there were no elevated SCC serum levels. Eight of 40 patients with breast, endometrial and ovarian cancer had raised SCC levels. In only two of 12 patients with benign gynecological diseases, SCC was also elevated. Sixty per cent of the patients with primary and 73% of the patients with recurrent cervical cancer showed pathological values; CEA was elevated in 31% and 51% respectively. The absolute values increased with the stage of the disease. Sixty-nine per cent of patients with squamous cell carcinoma had elevated levels. In five of nine adenosquamous carcinomas SCC was pathological.SCC shows a high sensitivity for squamous cell carcinomas of the cervix uteri. The tumor marker might be helpful in the control of primary therapy and follow-up of cervical cancer patients.

Evaluation of squamous cell carcinoma antigen as a new marker for lung cancer

Carcinoembryonic antigen (CEA) is the only tumor marker of proven, although limited, value for the management of patients with non-small cell lung cancer (NSCLC). The authors have prospectively assessed the potential value of a new tumor marker, squamous cell carcinoma antigen (SCC Ag), in a large series of patients with advanced lung cancer (LC). Squamous cell carcinoma antigen and CEA levels were measured in 382 healthy persons (N1 group), 90 patients with benign pulmonary diseases, and 291 patients with LC (129 with SCLC and 162 with NSCLC, including 96 with squamous LC). Carcinoembryonic antigen levels were higher in smokers than in nonsmokers, but smoking habits did not influence the serum concentrations of SCC Ag. Elevated values (above the 95th percentiles of N1, i.e., 7.5 ng/ml for CEA and 3.0 ng/ml for SCC Ag) were observed in 11.1% of patients with benign pulmonary diseases for both markers. Carcinoembryonic antigen was more sensitive than SCC Ag, even for squamous LC (56% versus 35% of elevated values, P less than 0.01). The specificity toward squamous LC was better, however, for SCC Ag, for which levels were elevated in only 8.5% of SCLC and in 18% of other forms of NSCLC, compared with 49% and 55%, respectively, for CEA. Moreover, measurement of SCC Ag and CEA levels did not give redundant information: thus, in squamous LC and SCC Ag level was elevated in 32% of the patients with a normal CEA level, increasing from 57% to 71% the proportion of patients with at least one elevated marker. Lastly, elevation of CEA or SCC Ag levels was an adverse prognostic factor in squamous LC (P = 0.05 for CEA; P = 0.07 for SCC Ag). In conclusion, SCC Ag appears to be worthwhile of further investigation in squamous LC. The authors found that this new marker provided additional information on CEA and that it was more specific for squamous LC than CEA.     

Clinical significance of osteopontin in esophageal squamous cell carcinoma: comparison with common tumor markers

OBJECTIVE: Osteopontin (OPN) is a secreted integrin-binding glycophosphoprotein that may have a role in head and neck squamous cell carcinoma (SCC). To evaluate the clinical significance of OPN in esophageal squamous cell carcinoma (ESCC), we compared plasma OPN levels with those of common tumor markers. METHODS: Preoperative plasma OPN levels were measured by enzyme immunoassay in 103 ESCC patients. Serum SCC antigen, Cyfra 21-1, and carcinoembryonic antigen (CEA) levels were also measured routinely at admission by radioimmunoassay. RESULTS: Plasma OPN levels ranged from 82.8 to 1,980 ng/ml. High OPN level was associated with lymph node metastasis (p = 0.05), but not with tumor histology or depth of invasion. The overall survival of the patients with high OPN levels was worse than that of those with low OPN levels (p = 0.02). SCC antigen and Cyfra 21-1 levels were associated with the depth of tumor invasion, the tumor diameter, lymph node metastasis, and the overall survival, but CEA was not associated with these clinicopathological factors. Combined evaluation of OPN plus Cyfra 21-1 or OPN plus SCC antigen was useful as an independent prognostic indicator. CONCLUSION: Measurement of the plasma OPN level, as well as serum SCC antigen and Cyfra 21-1, may help to predict the progression of ESCC.     

Multivariate analysis of the histopathologic prognostic factors of cervical cancer in patients undergoing radical hysterectomy.

Three hundred forty-five patients with invasive carcinoma of the uterine cervix, Stages Ib (211 patients) and II (134 patients), underwent radical hysterectomy and pelvic lymphadenectomy. The influence of histologic factors including histologic subtype, maximum depth of cervical stromal invasion, degree of stromal invasion, longitudinal tumor diameter, lymph-vascular space invasion, corpus invasion, parametrial invasion, vaginal invasion, and pelvic lymph node (PLN) metastases on survival were examined by multivariate analysis. Univariate analysis revealed that all the variables except corpus invasion and vaginal invasion were significant in survival (P less than 0.05). Among these variables, however, PLN metastases, histologic subtype, and longitudinal tumor diameter were identified as independent and significant prognostic factors by multivariate analysis using Cox regression models. The prognostic index (PI), defined by the model (an indicator of the patient's place in the prognostic spectrum), was able to divide the patients into three prognostic groups. The key factors in the definition of these groups were (1) squamous cell carcinoma, small tumor diameter, and no PLN metastases for the good prognostic group and (2) PLN metastasis in two or more node groups, adenocarcinoma with one positive PLN group, or squamous cell carcinoma with one PLN group and large diameter for the poor prognostic group. These prognostic findings could predict the prognosis more precisely than that of clinical staging.     

Tumor markers (CEA, CA 125, CYFRA 21-1, SCC and NSE) in patients with non-small cell lung cancer as an aid in histological diagnosis and prognosis. Comparison with the main clinical and pathological prognostic factors.

CEA, CA 125, SCC, CYFRA 21-1 and NSE were prospectively studied in 211 patients with non-small cell lung cancer and compared with clinical parameters (age, sex, Karnofsky Index, symptoms and smoking status), histopathological parameters (stage, histology, tumor size and nodal involvement), biological parameters (LDH and albumin) and the therapy used (surgery, chemotherapy or radiotherapy). Tumor marker sensitivity was CYFRA 21-1: 76%, CA 125: 55%, CEA: 52%, SCC: 33% and NSE: 22%. One of the tumor markers was abnormally high in 87% of the patients with locoregional disease and in 100% of the patients with metastases. Except for NSE, all tumor markers showed a clear relationship with tumor stage and histology and therefore enabled a better histological diagnosis. Abnormal CEA serum levels were mainly found in adenocarcinomas, CA 125 in large-cell lung cancers (LCLC) and adenocarcinomas and SCC in squamous tumors. Eighty-five percent of the patients with SCC levels >2 ng/ml had squamous tumors. Likewise, CA 125 levels <60 U/ml or CEA <10 ng/ml excluded adenocarcinoma or LCLC with a probability of 82 and 91%, respectively.     

Results of treatment of uterine cervix cancer by radiotherapy

The results of treatment of uterine cervix cancer by radiotherapy alone in 259 patients in the period January 1973 to December 1984 are reported. They are analyzed according to patients age, stage, tumor volume, extent of parametrial infiltration, hydronephrosis and nodal status. It is shown that age, tumor volume, extent of parametrial invasion and nodal metastases are the main prognostic factors. Analysis of pelvic failures shows that external radiotherapy followed by curietherapy seems to be the best method for patients with T2b and T3b tumors of small volume (less than 60 mm in diameter), particularly when parametrial infiltration is limited. Patients with T2b tumors of large volume (barrel shaped) seem to need a more aggressive approach, and a higher number of complications are therefore expected. Patients with T3b and massive parametrial infiltration, with T4 and nodal metastases need new and different approaches, possibly including adjuvant chemotherapy.     

Prediction of survival and recurrence by serum and cytosolic levels of CEA, CA125 and SCC antigens in resectable non-small-cell lung cancer.

Risk of death and risk of recurrence in 108 potentially curable non-small-cell lung cancer patients were analysed with respect of TNM stage, histological type and carcinoembryonic antigen (CEA), CA125 antigen and squamous cell carcinoma antigen (SCC) levels in serum and cytosol. CA125 and CEA levels were closely related to outcome figures. Multivariate analyses indicated that TNM stage and histological type had the best predictive power, but serum and cytosolic CA125 and serum CEA contained additional, independent prognostic information. Predictive information drawn from serum and cytosolic levels proved mutually complementary. We conclude that CA125 and CEA complement TNM classification and histological type for the purpose of quantifying risk of death or recurrence.     

The value of platelet-derived endothelial cell growth factor as a novel predictor of advancement of uterine cervical cancers

Serum platelet-derived endothelial cell growth factor (PD-ECGF) in patients with uterine cervical cancers revealed a significantly positive correlation with clinical stage and tumor size and with the advancement indicators lymph node metastasis, parametrial involvement, and vessel permeation in both squamous cell carcinomas and adenocarcinomas. The prognosis of the patients with high serum PD-ECGF was extremely poor, whereas the 36-month survival rate of the other patients with low serum PD-ECGF was 81.3% in squamous cell carcinomas and 80.0% in adenocarcinomas. Our data indicate that serum PD-ECGF levels reflect the status of advancement of uterine cervical cancers and thus may be recognized as a novel tumor marker for both squamous cell carcinomas and adenocarcinomas of the uterine cervix.     

Serum tumour markers in carcinoma of the uterine cervix and outcome following radiotherapy.

A study was made of the prognostic value of measurements of pretreatment serum marker levels in patients with carcinoma of the uterine cervix undergoing radiotherapy. The markers studied were carcinoma antigen 125 (CA125), squamous cell carcinoma antigen (SCC) and tissue polypeptide antigen (TPA). The levels of all three markers increased with disease stage. In a univariate analysis stratifying patients according to either median values or cut-off levels representing the top of the normal range, pretreatment levels predicted patient survival (follow-up times 1-4 years). In a multivariate analysis, disease stage was the most important prognostic variable and, after allowing for stage, only CA125 was a significant independent predictor of treatment outcome. These data suggest that, in carcinoma of the cervix treated with radiotherapy, pretreatment measurements of CA125, but not SCC and TPA, may have a role to play in defining prognosis.     

Prognostic factors in cervical cancer

Prognosis of cancer of the uterine cervix is determined mainly by clinical stage, histological type and degree of invasion or metastasis. Clinical stage is highly correlated with the prognosis of cancer. With regard to histological type, prognosis of adenocarcinoma is poorer than that of squamous cell carcinoma. The depth of invasion of the tumor and metastasis to the lymph node are also poor prognostic factors.     

宫颈癌淋巴结转移的高危因素及预后分析

背景与目的:盆腔淋巴结转移是影响宫颈癌预后的主要危险因素,但综合淋巴结转移的相关因素与预后分析的报道鲜见。本文综合分析宫颈癌淋巴结转移的高危因素、分布规律及预后因素,探讨淋巴结转移风险的评估以及淋巴结转移的治疗。方法:对205例在中山大学肿瘤防治中心妇科行广泛全宫切除加盆腔淋巴结清扫的病例进行回顾性分析。结果:总体盆腔淋巴结转移率为24.4%(50/205)。单因素分析显示,宫颈癌淋巴结转移的相关因素有治疗前血清SCC-Ag水平、临床分期、宫颈管及宫颈阴道部浸润深度、宫旁韧带侵犯;SCC-Ag超过4μg/L时,淋巴结转移的风险增加4.2倍(P<0.001,OR=4.212)。多因素分析表明,临床分期和宫颈管肌层浸润深度是淋巴结转移最主要的高危因素。淋巴结转移规律分析结果显示,转移淋巴结主要分布在闭孔及闭孔窝区(48.0%);60.0%转移病例存在多组淋巴结转移,并出现跳跃式转移现象。淋巴结转移与宫颈深肌层侵犯、宫旁浸润之间关系密切,72.0%的淋巴结转移者同时存宫颈深肌层浸润,90.9%的宫旁韧带浸润者出现淋巴结转移。预后分析结果显示,术后补充放疗者的5年生存率较未作放疗者高(89.1%vs45.5%,P=0.012)。结论:治疗前血清SCC-Ag>4μg/L、宫颈阴道部深肌层浸润、宫旁韧带受侵,特别是临床分期晚、宫颈管深肌层浸润时,宫颈癌淋巴结转移的风险提高。术前评估淋巴结转移风险高的病例,应行标准的宫颈癌根治术,以保证系统的淋巴结清扫及足够的宫旁切除范围。对病理证实有盆腔淋巴结转移的患者,术后补充放疗可改善预后。

Prognostic value of nm23 expression in stage IB1 cervical carcinoma

BACKGROUND: The purpose of this retrospective study was to evaluate the patterns of nm23 expression in stage IB1 squamous cell carcinoma of the uterine cervix, to compare nm23 expression with clinicopathological findings and to assess its prognostic value. METHODS: Twenty-seven patients with stage IB1 squamous cell carcinoma of the uterine cervix underwent abdominal radical hysterectomy and pelvic lymph node dissection. Expression of nm23 was studied immunohistochemically, followed by amplification and direct sequencing of exons 4 and 5 of the nm23 gene. RESULTS: Overexpression of nm23 was detected in 18.5% of the tumors and low expression was seen in 33.3%, while negative expression was found in 48.1% of the tumors. Deep cervical stromal invasion (> or =1/2) was found to be associated with the increased risk of lymph node metastases (odds ratio = 17.5). A significantly lower percentage of patients survived when nm23 overexpression was observed (p = 0.0063). Univariate analysis revealed that tumor size (2-3.9 cm), lymph node metastasis, tumor invasion into parametria, tumor invasion into blood/lymph vessel, squamous cell carcinoma (> or =2 ng/ml) and nm23 overexpression had a significantly lower recurrence-free survival rate of the patients. None of the above factors was significant according to multivariate analysis. There were no mutations in exons 4 and 5 of the nm23 gene in stage IB1 squamous cell carcinoma of the uterine cervix. CONCLUSIONS: This study suggests that expression of nm23 may be indicative of an unfavorable prognosis in patients with stage IB1 squamous cell carcinoma of the uterine cervix.     

Predictors for pathological parametrial invasion in clinical stage IIB cervical cancer

ObjectiveTo examine predictors of pathological parametrial invasion in clinical stage IIB cervical cancer, and to examine prognostic factors in pathological stage IIB disease.MethodsThis study is an ancillary analysis of a nation-wide retrospective cohort examining 6,003 clinical stage IB-IIB cervical cancers. Women with clinical stage IIB disease who underwent primary radical hysterectomy with lymphadenectomy were examined (n = 714). Multivariate analysis was performed to identify independent clinico-pathological factors for pathological parametrial invasion and to identify independent prognostic factors in pathological stage IIB disease.ResultsParametrial invasion was identified on the surgical specimen in 400 cases (56.0%, 95% confidence interval 52.4–59.7). On multivariate analysis, deep stromal invasion (DSI, adjusted-OR 3.922), multiple pelvic nodal metastases (adjusted-OR 3.266), lympho-vascular space invasion (adjusted-OR 2.333), and uterine corpus invasion (adjusted-OR 1.656) remained independent tumor factors for pathological parametrial invasion. In classification-tree models, tumors with DSI and multiple pelvic nodal metastases had the highest incidence of pathological parametrial invasion (75.0–87.7%); contrary, tumors without DSI had the lowest incidence (21.9%). Among patients with pathological stage IIB disease, the absolute difference in 5-year disease-free survival rates was 57.2%, ranging between 80.9% in those with squamous histology with none/single pelvic nodal metastasis and 23.7% in those with non-squamous histology with multiple pelvic nodal metastases.ConclusionIn clinical stage IIB cervical cancer, accuracy for pathological parametrial invasion is low-modest. With absence of DSI, only one in five clinical stage IIB diseases has pathological stage IIB disease. Survival of pathological stage IIB varies widely and is largely dependent on nodal factors.     

Serum alpha-N-acetylgalactosaminidase is associated with diagnosis/prognosis of patients with squamous cell carcinoma of the uterine cervix

Serum alpha-N-acetylgalactosaminidase (NaGalase) is responsible for the deglycosylation of vitamin D(3)-binding protein (Gc protein). The deglycosylated Gc protein cannot be converted into major macrophage-activating factor (MAF), leading to immunosuppression. NaGalase is universally detected in a variety of cancer patients, but not in healthy individuals (Cancer Res. 56 (1997) 2827-2831). However, the diagnostic/prognostic utility of NaGalase in squamous cell carcinoma (SCC) of the uterine cervix is not known. To address this issue, the serum NaGalase was quantitatively determined in 210 patients with different stages of SCC of the uterine cervix. NaGalase levels were increased with the progression of the cancer. After radiotherapy, the increased levels returned toward or to normal levels in early stages (FIGO stage I-IIB) but not in advanced stages (FIGO stage III-IV). The present study revealed that the amount of NaGalase in the patient's bloodstream reflects the tumor burden and aggressiveness of the disease. We conclude that NaGalase is an independent predictor of diagnosis/prognosis in SCC of the uterine cervix, and therefore suggest that quantitative NaGalase alteration may reflect important differences in the immunological functions of these neoplasms.     

Elevation of cyclooxygenase-2 is related to lymph node metastasis in adenocarcinoma of uterine cervix

In a previous study, we demonstrated that elevation of COX-2 is significantly associated with lymph node metastasis in squamous cell carcinoma (SCC) of cervix. The main objective of this study is to characterize the relationship between elevation of COX-2 and its possible clinical role in adenocarcinoma (AC) of cervix. Using immunohistochemistry, we examined COX-2 expression levels in 84 patients with AC of uterine cervix [71 ACs, 13 adenosquamous carcinomas (ASCs)]. Elevation of COX-2 was correlated with clinicopathological variables and p53 expression, as detected by immunohistochemistry. Elevation of COX-2 was detected in 13.0% (11 of 84) of the tumors. Elevation of COX-2 was significantly correlated with histologic type (AC 8.5% vs. ASC 38.5%, P=0.011). Both tumor stage and lymph node metastasis were correlated with elevation of COX-2 with a borderline significance (P=0.062 and 0.068, respectively). Elevation of p53 was not associated with elevation of COX-2. The association between lymph node metastasis and elevation of COX-2 was stronger in cases of AC than in cases of ASC (28.4 vs. 4.3%, P=0.023). According to the results of univariate analysis, elevation of COX-2 was significantly associated with decreased overall survival (P=0.003, log-rank test). However, multivariate analyses revealed that only tumor stage was independently associated with overall survival, suggesting that elevation of COX-2 itself may not be an independent prognostic factor. The present study shows that elevation of COX-2 may contribute to lymph node metastasis in AC of uterine cervix. This suggests that the potential therapeutic role of COX-2 inhibitors should be validated, not only in SCC, but also in AC of uterine cervix.
