This is a prospective, multicenter, non-interventional study aiming at investigating on the changes in QoL (Quality of Life) during the clinical management of low-grade lymphoma in elderly subjects and to possibly identify the most important factors at diagnosis and during treatment with an impact on QoL (Quality of Life).~The study plans to enroll 150 patients with a local histologically confirmed diagnosis of indolent non-Hodgkin lymphoma fulfilling all the inclusion/exclusion criteria who provide written informed consent will be included in the study. Any type of treatment is allowed by the study (immunotherapy, immunochemotherapy at full or reduced dose, radiotherapy).~All patients must undergo Comprehensive Geriatric Assessment (CGA) before starting any protocol treatment.~Baseline, post-treatment and follow-up instrumental assessments and response evaluation is done as part of the routine clinical management for patients with indolent NHL (Non Hodgkin Lymphoma) . Response evaluation and all other assessments planned for the EOT (end of treatment) should be planned also in case of early withdrawal, according to clinical practice.~HRQoL (Health-related Quality of Life) evaluation will be done at time of informed consent form signature prior to treatment start, at the end of the treatment (ranging from 1 month to 6 months according to the duration of the treatment) and after 1 year from the start of the therapy.~QoL (quality of life) assessment includes all scales of the EORTC-QLQ-C30 (European Organisation for Research and Treatment of Cancer Quality of life Questionnaire-Core 30) and the FACT-Lym-LymS (Functional Assessment of Cancer Therapy - Lymphoma - lymphoma-specific symptoms questionnaire).
Aims of this study are to describe the variation of QoL (Quality of Life) during the clinical management of low-grade lymphoma in elderly subjects and to identify the most important factors at diagnosis and during treatment with an impact on QoL (Quality of Life).
