Conjunctival squamous cell carcinoma: prognostic factors for the recurrence and metastasis and clinicopathological characteristics at an oncological hospital in Peru.

Background/aims: Conjunctival squamous cell carcinoma (CSCC) is the most frequent malignant tumour of the conjunctiva, with scarce recurrence and infrequent metastasis. The purpose of this study is to describe the clinical and pathological characteristics of this neoplasm and to identify the prognostic factors for recurrence and metastasis in a cancer hospital in Peru.

Materials And Method: A longitudinal, retrospective study of 176 consecutive patients diagnosed with SCC of the conjunctiva.

Medication possession ratio predicts antiretroviral regimens persistence in Peru.

Objectives: In developing nations, the use of operational parameters (OPs) in the prediction of clinical care represents a missed opportunity to enhance the care process. We modeled the impact of multiple measurements of antiretroviral treatment (ART) adherence on antiretroviral treatment outcomes in Peru.

Design And Methods: Retrospective cohort study including ART naïve, non-pregnant, adults initiating therapy at Hospital Nacional Cayetano Heredia, Lima-Peru (2006-2010).
