Mucoepidermoid carcinoma of the cervix uteri]

Among 147 re-examined carcinomas of the uterine cervix from the years 1970 till 1975 eight mucoepidermoid carcinomas were found and described. Furthermore we report on one case of a mucoepidermoid carcinoma in situ. The mucous substances are dyed with PAS and the Alcianblue-PAS reaction. A detailed definition of "minimal mucous appearance" is worked out in order to classify a carcinoma as a mucoepidermoid carcinoma. An increase in the mucous producing tendency of squamous cell carcinomas as well as in the number of mucoepidermoid carcinomas during the last two years is stressed.     

Preoperative hysteroscopic assessment of cervical invasion by endometrial carcinoma: a retrospective study

OBJECTIVE: The aim of this study was to evaluate the efficacy of hysteroscopy, using normal saline (NS) or carbon dioxide (CO2) as the distention medium, in assessing tumor invasion of the uterine cervix by endometrial carcinoma. METHODS: A retrospective study was conducted in 200 consecutive patients with endometrial carcinoma diagnosed from 1993 to 2000. Prior to definitive surgical treatment, hysteroscopy was performed using either NS or CO2 as the distention medium to determine whether the tumor had spread to the cervix. The uterine specimens obtained after hysterectomies were cut open for gross examination. Tumor invasion of the cervix as determined by hysteroscopy and gross examinations was compared with the pathological findings. RESULTS: Tumor invasion of the cervix was found in 41 (20.5%) cases on pathological examination. Hysteroscopy has an accuracy of 92.5% (185/200), a sensitivity of 68.3% (28/41), and a specificity of 98.7% (157/159), with a PPV of 93.3% (28/30) and a NPV of 92.4% (157/170) in determining cervical involvement. Assessment by gross inspection had 93.0% (186/200) accuracy, 68.3% (28/41) sensitivity, 99.4% (158/159) specificity, 96.6% (28/29) PPV, and 92.4% (158/171) NPV. There was no significant difference between the two assessment methods. When the results of hysteroscopy performed with different distention mediums were compared, the use of NS had a higher accuracy in determining tumor spread to the cervix (96.8% vs 88.7%, P = 0.03) and NPV (96.4% vs 88.4%, P < 0.05) than the use of CO2. CONCLUSIONS: Hysteroscopic assessment and gross examination of the uterine specimen had similar efficacy in detecting cervical invasion by endometrial carcinoma. Hysteroscopic examination using NS is more accurate than that which uses CO2.     

Metachronous metastases from renal cell carcinoma to uterine cervix and vagina: case report and review of literature

BACKGROUND: Although renal cell carcinoma (RCC) is characterized with unpredictable clinical presentation, multiple genital tract metastases are still surprising and mode of spread is obscure. CASE: We report a case of RCC metastases to uterine cervix and vagina 1 year after radical nephrectomy in a 19-year-old virgin. To our knowledge, this case is the second youngest patient with RCC metastasis to vagina, and also third patient with RCC metastasis to uterine cervix. CONCLUSION: Detection of genital lesion may precede diagnosis of RCC. The primary renal tumor was mostly left sided. Retrograde venous extension seems to be the most plausible mode of spread. Limited total experience and variability in therapeutic approach prevent generalizations regarding prognosis, optimal treatment and survival.     

Unusual form of superficial spreading microinvasive squamous cell carcinoma of uterine cervix involving the endometrium of uterus

Microinvasive squamous cell carcinoma of the uterine cervix is a recognized entity and is defined as carcinoma with invasion of less than 5 mm penetration of the stroma and seldom metastasized. Our patient was a 70-year-old, multiparous woman who had a microinvasive, cervical, squamous cell carcinoma. The tumor had spread superficially into the entire endometrial cavity up to the fundus, totally replacing the columnar epithelium. This is an extremely rare phenomenon, with fewer than 20 cases reported so far in the literature.     

Routes of lymphatic spread: a study of 112 consecutive patients with endometrial cancer

OBJECTIVE: The goal of this work was to assess different patterns of lymphatic spread to pelvic and para-aortic lymph nodes (LNs) in endometrial cancer as a function of the location of tumor within the uterus. METHODS: Between 1984 and 1999, 625 patients with endometrial cancer were managed with hysterectomy and node dissection at our institution. The present study includes the 112 (18%) patients who had positive pelvic and/or para-aortic LNs; 41 (37%) of them had cervical involvement. RESULTS: The external iliac was the most commonly involved pelvic LN site both in patients with tumor limited to the corpus and in those with cervical invasion. Isolated pelvic LN metastases to a single site were more frequently observed in external iliac LNs and obturator LNs in patients with tumor confined to the uterine corpus, whereas they occurred more commonly in external iliac and common iliac LNs in patients with cervical involvement. Metastasis to the common iliac LNs was more frequent in patients with disease extension to the cervix. In fact, common iliac LNs were positive in 67% of patients with cervical invasion, compared with only 30% of those with tumor confined to the uterine corpus (P < 0.01). Para-aortic LN invasion was significantly associated with obturator LN status. In fact, para-aortic LNs were positive in 64% of patients with positive obturator LNs compared with 23% of patients with negative obturator LNs (P = 0.01). All patients with positive para-aortic LNs and tumor invading the cervix had positive common iliac LNs. By contrast, when tumor was limited to the corpus, common iliac LNs were involved in only 27% of patients with positive para-aortic LNs. CONCLUSION: External iliac LNs are the most commonly involved LNs in endometrial cancer. Compared with carcinomas limited to the uterine corpus, endometrial cancers invading the cervix spread more readily to the common iliac LNs. Furthermore, these data suggest that para-aortic LN metastases spread via a route shared by the common iliac LNs when tumor involves the cervix but spread predominantly via a route common to the obturator LNs (and/or external iliac LNs) when the primary tumor site is the corpus only.     

Hepatic resection for metastatic squamous cell carcinoma from the uterine cervix.

A solitary hepatic tumor was diagnosed 3.5 years after a 67-year-old woman had undergone radical hysterectomy and postoperative irradiation for stage Ib squamous cell carcinoma of the cervix. Hepatic resection confirmed squamous cell carcinoma that had metastasized from the uterine cervix. One year and 10 months following hepatic resection, this patient is doing well with no evidence of any recurrence. This is a report of successful hepatic resection for metastatic carcinoma from the uterine cervix.     

宫颈鳞癌和腺癌中微血管密度和基质金属蛋白酶-2 、9及其抑制剂-1、2表达的研究

目的通过观察肿瘤微血管密度(MVD)及MMP-2、MMP-9和TIMP-1、TIMP-2在宫颈鳞癌与腺癌组织中的表达情况,在蛋白水平探讨宫颈腺癌较鳞癌恶性程度高的可能原因.方法采用免疫组织化学方法(SP) 检测40例宫颈鳞癌和20例宫颈腺癌组织的MVD和MMP-2、MMP-9、TIMP-1、TIMP-2蛋白的表达情况.结果MVD在宫颈腺癌中较鳞癌高.MMP-2在宫颈鳞癌的阳性表达强度较腺癌高(P=0.006);MMP-9、TIMP-1在腺癌的阳性表达较鳞癌高(P=0.078,P=0.000);TIMP-2在两组间比差异无显著性(P＞0.05).在宫颈癌的临床病理特征中,MMP-2和MMP-9在鳞癌和腺癌中的表达不一,而TIMP-1始终是在腺癌中的表达较鳞癌高.结论宫颈腺癌较鳞癌恶性程度高的原因,可能与较高的MVD和TIMP-1的高表达有关.     

Co-existent carcinosarcoma and adenoid basal carcinoma of the uterine cervix and correlation with human papillomavirus infection.

A case of carcinosarcoma associated with an adenoid basal carcinoma of the uterine cervix in an 84-year-old woman is described. The tumor formed a pelvic mass, and total hysterectomy with bilateral salpingo-oophorectomy was performed. The tumor was 17 cm in maximal dimension, arose in the posterior wall of the uterine cervix, and had a solid and cystic, focally myxoid sectioned surface. The tumor was composed of keratinizing squamous cell carcinoma and a mostly nonspecific sarcomatous component with focal chondrosarcomatous differentiation. Multiple foci of adenoid basal carcinoma were observed in the adjacent cervical wall. The HPV L1 gene was detected by PCR in each of the carcinomatous and sarcomatous components of the carcinosarcoma and the adenoid basal carcinoma. To our knowledge, this is the fifth case of coexisting carcinosarcoma and adenoid basal carcinoma of the uterine cervix in the English language literature.     

Mucoepidermoid carcinoma of uterine cervix stage IB. Long-term follow-up, histochemical and immunohistochemical study.

Twelve women with mucoepidermoid carcinoma of the cervix uteri were followed for 2-15 years after diagnosis. Three patients died within 14 months. All had lymph node metastases and/or vascular involvement and exhibited tumor invasion to a depth of 1.2-3.2 cm. Mucoepidermoid carcinoma is defined as a tumor with the appearance of squamous cell carcinoma without any glandular pattern and with demonstrable intracellular mucin. The mucin is best demonstrated by alcian blue and periodic acid-Schiff-diastase. In 265 cases of squamous cell carcinoma, stage IB, lymph node metastases were present in 14%. In the cases of mucoepidermoid carcinoma, the prevalence of nodal metastases was 33%. Because mucoepidermoid carcinomas appear to be more aggressive lesions than squamous cell carcinomas are, it may be advisable to stain all cervical squamous carcinomas for mucin if they demonstrate finely vacuolated cytoplasm and lack peripheral palisading. Immunohistochemical studies for carcinoembryonic antigen (CEA), keratin, and epithelial membrane antigen were positive in all tumors to varying degrees. The detection of CEA may be of additional help in establishing a diagnosis.     

Lymphoepithelial-like carcinoma of the uterine cervix; a case report

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is a rare variant of squamous cell carcinoma of the uterine cervix. This tumor is characterized by nests of poorly differentiated epithelial cells surrounded by a prominent lymphocytic infiltration. Despite the poorly differentiated pathological findings, it appears to have a better outcome than the usual squamous cell carcinoma of the uterine cervix. Therefore, it is quite important to differentiate this tumor from poorly differentiated squamous cell carcinoma and lympho-proliferative disorders of the cervix. LELC arising from the nasopharynx has been suggested to be associated with Epstein-Barr virus (EBV), whereas the involvement of EBV in LELC of the uterine cervix is still controversial. In addition, the role of high-risk human papilloma virus (HPV) in this type of tumor remains unknown. We report a case of LELC of the cervix with diagnosis on the basis of histopathology in a 52-year-old Japanese woman who presented with a history of continuous bleeding post menopause. We also examine the association of EBV and HPV in this case.     

宫颈大细胞神经内分泌癌的诊治进展

宫颈大细胞神经内分泌癌(large cell neuroendocrine carcinoma,LCNEC)是一种罕见类型的宫颈恶性肿瘤,因其复发率高,易发生早期转移,具有高度侵袭性,故即使在早期经系统治疗,其预后也极差。宫颈LCNEC临床表现与其他类型宫颈癌无异,目前术前及术后标本的组织病理学及免疫组织化学检查是其主要的诊断方法。一部分宫颈LCNEC患者存在高危型人乳头瘤病毒(HPV)感染,但该病发生与高危型HPV感染无关。由于其独特的生物学特性,所宫颈LCNEC的预后较差,随访较其他类型宫颈癌更加频繁。宫颈LCNEC的治疗方案主要是通过回顾总结得到,目前尚无统一治疗方法。因其与宫颈小细胞神经内分癌有相似的生物学特征,所以其治疗方案主要参考宫颈小细胞神经内分泌癌,主要采用联合治疗方法,手术联合放化疗有助于提高患者的远期生存率,因此有关宫颈LCNEC的诊治研究更为迫切。     

Clinical studies on intravaginal administration of CDDP for dysplasia, carcinoma in situ and microinvasive carcinoma of the uterine cervix]

We attempted CDDP (cis-diaminedichloroplatinum) intravaginal administration by directly exposing the uterine cervix to CDDP in cases of dysplasia of the uterine cervix and cervical intraepithelial and micro-invasive carcinoma. Out of 12 patients, 7 had dysplasia of the uterine cervix (dysplasia was mild in 4, of an intermediate level in 1, 4 with mild dysplasia, 1 with and advanced in 2); 3 had carcinoma in situ, and 2 had microinvasive carcinoma. For CDDP intravaginal administration, a gauze tampon containing CDDP (5mg) was inserted into the vagina. CDDP administration was repeated daily for 10 days. The total dosage of CDDP administered was 50mg (new paragraph). During this period, vaginal cytologic examination was conducted and total plasma Pt content was determined daily for all. Following the completion of CDDP administration, the uterine cervices of those with dysplasia were histologically examined. For those with carcinoma in situ and microinvasive carcinoma, simple total hysterectomy was performed after intravaginal administration of CDDP to determine its therapeutic efficacy and the Pt concentration of the tissue; 1. In the 7 cases of dysplasia, dysplastic cell degeneration was observed 1-2 days after the start of intravaginal CDDP administration and these cells disappeared in all cases after its completion. 2. Sixteen histological sections of the resected cervical specimens from the 3 cases of carcinoma in situ showed complete disappearance of cancerous cells. 3. In the 2 cases of microinvasive carcinoma, no tumor cells were detected in one case; in the other case, tumor cells persisted in part of the resected specimen.(ABSTRACT TRUNCATED AT 250 WORDS)     

Coexistent squamous cell carcinoma and adenocarcinoma of the uterine cervix

The clinical and pathological features of 20 patients with coexistent squamous cell carcinoma and adenocarcinoma of the uterine cervix have been analyzed. Various combinations of in situ and invasive carcinomas were found. Located adjacent to each other and at times intermingling, these lesions probably originated from the subcolumnar reserve cells of the transformation zone. They are early lesions and may be precursors of adenosquamous and mucoepidermoid carcinomas of the cervix. The diagnosis of these double carcinomas depends upon being aware that the two entities may coexist in the same cervix. Treatment is conventional, and the prognosis is not worsened by the presence of the two types of neoplasms.     

P~(16)蛋白在宫颈癌中的表达及其临床意义

目的：研究抑癌基因P16与宫颈癌发生、发展及患者预后的关系。方法：用免疫组化ABC法检测了10份正常宫颈组织、16份慢性宫颈炎及123份宫颈鳞癌组织中P16的表达情况。结果：P16在宫颈癌中检出率为43．90％，明显低于正常宫颈（80．00％）及宫颈炎组织（68．75％），P＜0．01。其中伴淋巴结转移的宫颈癌中P16蛋白表达率（22．22％）是显著低于无淋巴结转移者（61．11％），P＜0．05。P16蛋白表达阳性者5a存活率为52．63％，而阴性者仅为29．79％，P＜0．05。结论：P16蛋白的突变与缺失可能与宫颈癌的发生、发展密切相关。     

Uterine body invasion of carcinoma of the uterine cervix as seen from surgical specimens

To estimate the actual states of uterine body invasion of carcinoma of the uterine cervix, 301 radically hysterectomized specimens were reviewed histologically. Incidence of uterine body invasion was 21.6% in all cases (65 cases out of 301), 7.8% in stage Ib, 25.5% in stage IIa, and 38.2% in stage IIb. Most of the positive invasion cases had spread to other surrounding tissues. Vaginal wall was invaded in 58.5% of all positive cases, parametrial infiltration was recognized in 87.7%, and pelvic lymph node metastasis was seen in 52.3%. On the contrary, in negative cases these were 33.9, 19.1, and 15.7%, respectively. There was a higher incidence of the L type of Imai's CPL classification among positive cases of uterine body invasion than among negative cases (81.5% vs 38.1%). When cervical cancer spread into the uterine body, peritoneal carcinomatosis and distant metastasis increased. Thus the outcome of patients with positive invasion was, naturally, poor. Patients with negative invasion had a 5-year survival rate of 92.4%, compared to 53.8% in patients with positive uterine body invasion. These results suggest that uterine body invasion of carcinoma of the uterine cervix is an important prognostic factor and treatment should be modified in such cases.     

Intralesional injection for hepatic metastasis from cervical carcinoma. A report of two cases.

BACKGROUND: The treatment of isolated hepatic metastasis from carcinoma of the uterine cervix has yet to be established. We tested the efficacy of percutaneous injection of ethanol and acetic acid as a curative-intent treatment modality for this rare event. CASES: Under real-time sonographic guidance, two patients with a solitary hepatic metastasis from carcinoma of the cervix were treated with 99.5% percutaneous ethanol injection (one patient) and 50% percutaneous acetic acid injection (the other patient). The treatment was repeated weekly if laboratory data permitted and aspiration cytology interpreted on site showed tumor cells. Cytology after complete treatment showed no residual tumor cells in either case. Both patients had no evidence of disease during follow-up for 12 and 24 months, respectively. CONCLUSION: Treatment was successful in two patients with isolated hepatic metastatic lesions from carcinoma of the cervix who received percutaneous injection of 99.5% ethanol or 50% acetic acid.     

Multisystem sarcoidosis and carcinoma of the uterine cervix: An unusual association

Abstract. Alliot C, Barrios M, Desplechain C. Multisystem sarcoidosis and carcinoma of the uterine cervix: An unusual association.
Sarcoidosis malignancy syndrome is a rare phenomenon which remains controversial. We report here the case of a 46-year-old woman presenting with multisystem sarcoidosis 12 months after the completion of combined treatment for stage III squamous cell carcinoma of the uterine cervix; at the time she was still in complete remission of the tumor. The outcome was rapidly favorable under oral corticosteroid therapy. The time interval between the two illnesses as well as patient's age strongly suggest a relationship. Possible pathophysiologic mechanisms and the literature regarding uterine tumors are briefly reviewed.     

Value of endocervical curettage in the staging of endometrial carcinoma

The prognosis for women with endometrial cancer correlates with stage of disease. Spread to the cervix distinguishes Stage II from Stage I disease. To assess the accuracy of endocervical curettage (ECC) in predicting cervical involvement by endometrial adenocarcinoma, we examined and assigned to one of four groups the ECC from 147 women treated between 1980 and 1985. Ultimate determination of spread to the cervix was based on examination of subsequent hysterectomy specimens. In the hysterectomy specimen 19 of 147 women (13%) had cervical involvement demonstrated. Five women had tumor clearly within the endocervical tissue of the ECC (Group I), and three of these five (60%) had spread of tumor to the cervix in the hysterectomy specimen. At hysterectomy, 13 of 41 women (32%) with tumor present but not contiguous with endocervical tissue within the ECC (Group II) had cervical involvement. Of the 80 women without tumor in the curettage (Group III), one (1.2%) had cervical involvement by tumor at hysterectomy. Two of the 21 women (9.5%) with curettings considered insufficient for diagnosis (Group IV) had spread of adenocarcinoma to the cervix within the hysterectomy specimen. We also compared the results of ECC performed at our institution with those performed at referring hospitals and found a significant difference between them in ability to obtain definitive results. We conclude that (a) the absence of carcinoma in ECC is highly predictive of absence of cervical involvement by endometrial carcinoma; (b) ECC having tumor within endocervical tissue is a good predictor of cervical involvement by tumor.(ABSTRACT TRUNCATED AT 250 WORDS)     

Surgical management of pulmonary metastasis from carcinoma of the uterine cervix

The present study was designed to evaluate the efficacy of surgical management of pulmonary metastasis from carcinoma of the uterine cervix. We saw 609 cases of carcinoma of the uterine cervix from 1979 to 1987, and during the same period also saw 110 cases of recurrent carcinoma of the uterine cervix. Fourteen of these 110 cases were identified as having pulmonary metastasis, and in 11 of 14 cases the recurrent tumors were limited to the lung. Seven of these 11 cases underwent pulmonary resection. Six of the 7 survived more than 2 years after pulmonary resection. Among them, 1 patient has survived more than 4 years, and 1 patient more than 8 years. The tumor cells were thought to metastasize to the lung through the vertebral venous plexus (Batson's plexus) which was suggested as a metastatic route by Thomford et al. in their report on recurrent colon cancer. As a result of this study, if the recurrent tumor is clinically limited to the lung in patients with recurrent carcinoma of the uterine cervix, they should be treated by surgical resection of the pulmonary tumor.     

Ovarian Metastasis on Transposed Ovary in Patients Treated for Squamous Cell Carcinoma of the Uterine Cervix: Report of Two Cases and Surgical Implications

BACKGROUND: To discuss risk factors for ovarian metastasis in a transposed ovary in patients treated for cervical cancer. CASES: Cases were two patients with ovarian metastasis in a transposed ovary in a series of 107 patients. These two patients were treated for a Stage IB squamous cell cervical cancer and presented with a tumor devoid of extrauterine spread (absence of nodal involvement or distant metastases) but with involvement of the uterine corpus. Furthermore, lymphovascular space involvement (LVSI) in the cervix or paracervix was present in both patients. CONCLUSIONS: Ovarian transposition should be performed in patients < or =40 years of age with a small invasive cervical carcinoma (< 3 cm) treated by primary surgery. This procedure should not be performed in patients with bulky tumor and/or in patients with LVSI.
