An extremely indolent T-cell leukemia: an 18-year follow-up

Area of Science:

• Hematology
• Oncology

Background:

• T-cell prolymphocytic leukemia (T-PLL) is a rare, aggressive lymphoid malignancy.
• T-PLL typically presents with lymphocytosis, splenomegaly, and a poor prognosis, with median survival under 1 year.
• Some T-PLL cases exhibit an indolent course before progression.

Purpose of the Study:

• To report long-term follow-up of a rare indolent T-cell prolymphocytic leukemia case.
• To observe the disease course and patient status over an extended period.

Main Methods:

• Case study with extended follow-up.
• Monitoring of patient's clinical status and symptoms related to T-cell prolymphocytic leukemia.

Main Results:

• The patient, initially diagnosed with indolent T-PLL in 1995 and reported in 2002, remained asymptomatic for an additional 11 years.
• Total follow-up extends over 18 years from initial diagnosis, with sustained lack of disease-related symptoms.

Conclusions:

• This case demonstrates the possibility of a prolonged, asymptomatic indolent phase in T-cell prolymphocytic leukemia.
• Extended follow-up is crucial for understanding the natural history of rare T-PLL variants.
