    Evaluation of the prognostic significance of clinical features of tumoral lesions in an extensive series of mycosis fungoides
    (Wiley, 2024) Atci, Tugba; Ozturk Sari, Sule; Besisik, Sevgi; Baykal, Can; Büyükbabani, Nesimi; Koç University Hospital
    Background: Tumors indicating the advanced stage of mycosis fungoides (MF) have a rich clinical spectrum. Although it is known that the prognosis of MF generally worsens following the development of tumors, some cases may have a relatively indolent course, and the role of clinical characteristics regarding prognosis has still not been well understood. Methods: MF patients were retrospectively evaluated regarding the development of tumors. Besides demographic characteristics, data of the subtype and stage of the disease were recorded. The clinical features of tumors, including number (<5, 5-10, 11-20, or >20), location, dimension (diameter of >= 5 cm), presence of ulceration, and surrounding inflammation, were noted. Univariate and multivariate analyses evaluated the relationship between overall survival (OS) with demographic and clinical features. Results: Among 730 consecutive MF patients, tumors developed in 8.2% (n = 60), of whom 46.7% were diagnosed with advanced-stage MF from the beginning. The most common subtype was folliculotropic MF (53.3%). Most patients (55%) had multiple tumors, and the most frequent localization was the trunk (71.7%). Most tumors presented as smooth-surfaced, indurated papules and/or nodules (70%), while others were reddish-purple, occasionally accompanied by ulceration (50%), perilesional inflammation (23.3%), and attaining large dimensions (25%). Mortality was recorded in 51.7% of patients, and the 5-year OS rate from the diagnosis of tumors was 49%. Independent poor prognostic factors for OS in multivariate analysis included older age at the time of diagnosis, presence of tumors at the initial MF diagnosis, presence of over 20 tumors, and the existence of large tumors. Conclusions: Tumoral MF seen in older patients, the first diagnosis of MF in this stage, presenting with generalized and large tumors, seems to be a predictive factor for OS.
