Pelvic lymph node metastasis in microinvasive adenocarcinoma of cervix

Microinvasion of cervical cancer was defined according to the International Federation of Gynecologists and Obstetricians classification as a depth of invasion of no greater than 3 mm and a horizontal dimension of no greater than 7 mm. Although the status of the lymph nodes is not included in the staging of cervical cancer, the presence or absence of lymph node metastasis provides important prognostic information and influences decision-making for treatment. For patient with stage IA1 microinvasive squamous cell carcinoma, the incidence of lymph node involvement is estimated to be 1%, but very little is known about lymph node metastasis in microinvasive adenocarcinoma of cervical cancer. We have experienced a case of pelvic lymph node metastasis in microinvasive adenocarcinoma of cervix with a depth of invasion of 3 mm or less, with no lymphovascular invasion. So, we report the case with brief review of literatures.

Analysis of Outcomes of Microinvasive Adenocarcinoma of the Uterine Cervix by Treatment Type

To estimate the risk of metastatic disease in microinvasive adenocarcinoma of the cervix in a large cohort. Thirty-six cases were identified from the Mayo Clinic health information database, and 30 cases were identified using the University of Southern California gynecologic oncology patient database. Histopathology was reviewed by a single pathologist at each institution to confirm histologic subtype and grade of tumor, depth of invasion, linear extent of the tumor, the presence or absence of lymphovascular space invasion, margin status, parametrial involvement, and the presence of nodal metastasis. Fifty-two patients had stage IA1 cancers and 14 had stage IA2 cancers. Therapy ranged from cold knife conization to radical hysterectomy with lymphadenectomy. No parametrial involvement was noted in any of the patients who underwent parametrial resection. One patient with stage IA1 cancer had micrometastasis to a pelvic lymph node. No recurrences were noted with an average follow-up of 80 months. The management of microinvasive adenocarcinoma remains controversial, and radical therapy is applied more frequently to microinvasive adenocarcinoma than microinvasive squamous cell carcinoma of the cervix. The risk of extracervical disease is low and the risk of recurrence is not affected by the radicality of resection. Our data suggest that microinvasive adenocarcinoma is amenable to treatment with nonradical surgery. III.

In-situ and microinvasive adenocarcinoma of the uterine cervix. A clinical, cytologic and histologic study of 14 cases.

In-situ and microinvasive adenocarcinoma of the uterine cervix. A clinical, cytologic and histologic study of 14 cases. Am J Clin Pathol 64: 155-70, 1975. The clinicopathologic features of 14 cases of in-situ and microinvasive adenocarcinoma of the cervix, encountered during the period 1961-1974, form the basis of this report. Seven cases represent examples of in-situ and seven, microinvasive adenocarcinoma. Severe dysplasia and carcinoma in-situ of the squamous epithelium were coincidental finds in 12 patiients. Papanicolaou smears were abnormal in all 14 patients. In nine, malignant glandular cells were identified. Five smears contained both malignant squamous and glandular cells. The mean age of the 14 patients was 38.4 years. Thirteen patients had borne one to six children. Two were pregnant at the time of diagnosis, and four were on birth control medication. Thirteen of the patients underwent conization biopsy. Hysterectomy in one form or another was curative in all. The relatively infrequent occurrence of in-situ adenocarcinoma is probably due to the low incidence of cervical adenocarcinoma and to the fact that the lesion is focal and easily overlooked. Five of the cases in the present series were a chance finding in a review of 200 consecutive cone biopsies of the cervix. The resemblance of the in-situ lesions to carcinoma and the presence of morphologically similar glandular tissue adjacent to foci of microinvasion suggests that the in-situ lesion is the precursor of invasive adenocarcinoma of the cerivs.
