Acantholytic squamous cell carcinomas of the cervix: A case series.

Squamous cell carcinoma of the uterine cervix is considered the most common histologic variant of cervical cancer, with well-established treatment protocols and prognosis. An infrequent histologic variant of cervical squamous cell carcinoma is the acantholytic variant (ASCC), which is characterized by discohesive cells that result in a pseudoglandular and/or angiomatoid pattern of growth. This variant of squamous cell carcinoma has been regarded as having a poor prognosis at certain anatomic sites such as the head and neck and vulva. In the uterine cervix, the importance of this variant has not been yet established. A ten-year retrospective review of squamous cell carcinoma of the uterine cervix was performed to identify this variant and correlate it with clinical characteristics to better define its prognostic implications. During the study period 19 cases were identified containing from 10 to 80% acantholytic component. Mean age at diagnosis was 49 years. Clinical stages were 1A2 (1 case), Ib1 (16), and IIA1 (2). Median follow-up was 92 months. When compared with controls, ASCC were larger in size (1.4 vs 3.5 cm), had deeper involvement of the cervical stroma (21 vs 47%), had more lymph node metastasis (8 vs 26%), more frequent recurrences (4 vs 15%) and a shorter disease-free survival; however, no statistical differences were identified in overall survival. ASCC is an infrequent variant of cervical cancer which seems to have an impact on disease-free survival but no in overall survival.

Prognostic molecular biomarkers in endometrial cancer: A review.

BACKGROUND: Endometrial cancer (EC) is the fourth most common malignancy in women worldwide and the most common gynecological cancer in developed countries. The endometrioid subtype has an excellent prognosis with conventional treatment; however, recurrence reduces overall survival. OBJECTIVE: Describe the most relevant evidence regarding selected potential molecular biomarkers that may predict overall survival (OS), relapse-free survival (RFS), and cancer-specific survival (CSS) in EC. METHODS: An exhaustive search was performed in PUBMED with the search terms endometrial cancer, molecular biomarker, and survival. We selected original articles written in English about endometrial cancer, molecular biomarkers, and that included survival analysis published between January 2000 and December 2016. RESULTS: Several molecular prognostic biomarkers have been studied in terms of survival and therapeutic response in women with endometrial cancer; hormone receptors, microRNAs, and other molecules have emerged as potentially useful biomarkers, including HER2, p21, HE4, PTEN, p27, ANCCA, and ANXA2. CONCLUSIONS: The use of biomarkers in the assessment of OS, RFS, and CSS requires large trials to expand our understanding of endometrial carcinogenesis. Several molecular markers are significantly associated with a high tumor grade and advanced clinical stage in EC and, therefore, could have additive effects when combined.
