Research Interests

My primary area of specialization is gynecological pathology, while my clinical focus includes also genitourinary pathology and soft tissue sarcomas. I have participated in single or multi-institutional studies primarily conducting translational-type research on gynecologic tract neoplasms. In the past, I have conducted research in uterine and ovarian lesions, including endometrial carcinoma, ovarian serous neoplasms, mesonephric lesions and mucinous and Brenner ovarian tumors amongst other gynecological lesions.

Recently, my interest has been devoted to study endocervical carcinoma and in developing a new risk stratification system to better predict the risk of lymph node metastasis in patients with these tumors, as well as demonstrate that patients with some of these tumors can be treated with conservative modalities, hence decreasing the morbidity and complications of lymphadenectomy.

In brief, endocervical adenocarcinoma can be stratified based on the morphological pattern of invasion into 3 groups: tumors characterized by well-demarcated glands with rounded contours, frequently forming clusters or groups and sometimes showing relatively well preserved lobular architecture are designated as pattern A. These tumors demonstrate a pushing or expansile pattern of invasion and behave in an indolent fashion. Tumors with early or limited, localized destructive invasion, defined as individual or small clusters of tumor cells or fragments of glands within a desmoplastic, edematous, or inflamed stroma adjacent to an intact gland are designated pattern B. These tumors have focal or multifocal areas characteristic of pattern B in a background of pattern A type glands.  Lymphovascular invasion may be seen in pattern B tumors. Less than 5% of patients with these tumors develop lymph node metastasis. While the tumors with more aggressive features, including diffusely infiltrative glands, usually associated with extensive, diffuse desmoplastic response are designated pattern C. Tumor glands show a destructive (or tentacular) pattern with angulated and often incomplete glands and open to the stroma. Most lymph node metastasis, recurrences and death due to disease occurred in patients with these tumors.

Dr Roma earned his medical degree at the Buenos Aires University and completes Anatomic Pathology residency in his home country of Argentina. He continued his training in Anatomic and Clinical Pathology at the Cleveland Clinic followed by a Fellowship in Gynecological Pathology at the MD Anderson Cancer Center.

After two years as an attending at Washington University in St Louis, Dr. Roma was recruited back to Cleveland Clinic and stayed as an attending there for 6 years with clinical duties and research interests in Gynecological and Genitourinary Pathology. There he was promoted to Associate Professor of Pathology, was author of numerous publications and gave several lectures at national and international meetings including USCAP, ASCP, CAP and IAP/ESP.

Dr Roma was recently recruited to the University of California San Diego as an Associate Professor of Pathology and Associate Director of Surgical Pathology and continues his clinical duties as well as research endeavors.
