Our study reviews the pathology in 32 cases of stage IA2 and 205 cases of small diameter stage IB1 cervical cancer Methodology Pathology review was done including the „third dimension’ measure in stage IA2 not exceeding 7 mm and maximal measure in small diameter IB1 not exceeding 20 mm.
Initially described by Mestwerdt in 1947, cases of microinvasive carcinoma of the uterine cervix represent a group of patients with better prognosis with the possibility of needing less radical treatment. 1 Despite that microinvasion has been defined since the 1940s, the depth of invasion, as well as the lateral extension, are subjects of various classifications and certain controversy.
Less radical surgery can be carefully considered for these patients. INTRODUCTION Microinvasive cancer of the uterine cervix represents a stage in the continuum of cervical carcinogenesis that begins with persistent infection with the human papillomavirus (HPV) and ends with frankly invasive cancer. 1. Clin Obstet Gynecol. 1990 Dec;33(4):846-51.
A gynaecologist caring for women with cervical cancer should, ideally, undertake a subspecialist training course. 1989-08-01 · The new definition for Stage IA cervical cancer incorporates measurement of both depth of in- vasion from the base of the epithelium and lateral spread, but ignores lymph-vascular space invasion, growth pat- tern, degree of differentiation, and stromal inflammatory response. Objective The aim of this study was to evaluate the prognosis and recurrence of microinvasive squamous cervical (MIC) cancer stage IA1 in women treated conservatively or by hysterectomy, and followed-up to 20 years. Methods It was studied in a cohort of 139 women with MIC, 41 definitively managed by conization and 98 by hysterectomy from January 1994 to December 2003 and followed-up until 2013 2018-11-24 · Microinvasive Carcinomas of Breast are rare tumors of the breast. They usually occur in a background of in situ carcinomas (such as high-grade ductal carcinoma in situ), and the invasive component by definition is less than 1 mm. 90% of cervical cancers and they possess transformingviraloncogenes(E6andE7). 96 JClinPathol1998;51:96–103 Departmentof Pathology,University ofEdinburgh,Medical School,TeviotPlace, EdinburghEH89AG, UK MJArends Departmentof Reproductive Pathology,University ofManchester,St Mary’sHospital Women&Children, WhitworthPark, ManchesterM130JH, UK Microinvasive SCC and microinvasive AC are currently diagnosed and treated based on the results of conization 4.
Conservative treatment becomes the preferred option for all microinvasive lesions even for patients who are prepared to trade-off a small (e.g. 2%) risk of death in order to retain their fertility.

In 1985, the International Federation of Gynecology and Obstetrics (FIGO) defined Stage IA as "preclinical invasive carcinoma, diagnosed by microscopy only," subdividing it into Stage IA1 or "minimal Pelvic lymph node evaluation is essential because lymph node metastasis may occur even in early stages. The lack of parametrial invasion in this study reinforces the knowledge that the select group of patients with microinvasive cervical carcinoma stages IA1 LVSI and stage IA2 have a very low risk of parametrial infiltration. Microinvasive cancer of the uterine cervix represents a stage in the continuum of cervical carcinogenesis that begins with persistent infection with the human papillomavirus (HPV) … Microinvasive cervical cancer.
The major tenets in accurately assessing tumor size in patients with early stage cervical cancer currently include physical examination, imaging studies, and pathologic evaluation. It is estimated that when comparing clinical stage based on physical examination and final pathology, the concordance diminishes as stage increases: 85.4%, 77.4%, 35.3%, and 20.5% for stage IB1, IB2, IIA, and IIB
Conization alone followed by careful observation is preferred over hysterectomy for treating cervical carcinoma in situ (CIS) and microinvasive cancer patients, especially in terms of … No. 5 CERVICAL MICROINVASIVE CANCER Hasumi el al. 929 tionable invasion are included, or if external radio- therapy is given prior to lymphadenectomy.
Cervical cancer (CC) is usually initiated by infection with high-risk types of the human papillomavirus (HPV). 1 Two major histotypes of CC exist: squamous cell carcinomas (SCCs; 80%) and
Microinvasive cervical cancer, defined as FIGO stage IA1 with no lymphovascular space invasion (LVSI), has a < 1% risk of lymph node metastases and may be managed conservatively with conization using LEEP, laser, or cold knife. 2017-05-27

Cervical cancer encompasses several histologic types, of which squamous cell carcinoma (SCC) is the most common (70 percent) ().The incidence of invasive cervical adenocarcinoma and its variants has increased dramatically over the past few decades; this cell type now accounts for approximately 25 percent of all invasive cervical cancers diagnosed in the United States []. 2012-01-01 · For women with microinvasive cervical cancer, it is unclear whether there is a difference in survival between stage IA1 and IA2 tumors.12, 13, 14, 17 In a prior analysis of SEER data, Smith et al 14 found no differences in the frequency of positive lymph nodes or death for stage IA1 and IA2 tumors.

Microinvasive squamous cervical cancer 107 chapter 13. Microinvasive squamous cervical cancer This chapter deals with microin-vasive squamous cervical cancer (Fig. 13.1). It is an introduction to the disease and not a reference text. A gynaecologist caring for women with cervical cancer should, ideally, undertake a subspecialist training course.
