Primary bone lymphoma: tunisian multicentric retrospective study about 32 cases
La Tunisie Medicale
|November 16, 2018
Summary
Primary bone lymphomas (PBL) are rare but treatable. Chemotherapy (CT) with Rituximab shows high response rates and improves survival in Tunisian patients, despite late diagnosis.
Area of Science:
- Oncology
- Hematology
- Epidemiology
Background:
- Primary bone lymphomas (PBL) are rare malignancies.
- Understanding their characteristics is crucial for effective management.
Purpose of the Study:
- To describe the epidemiology, clinical features, treatment, and prognosis of PBL in Tunisia.
- To evaluate treatment outcomes in a Tunisian cohort.
Main Methods:
- Retrospective analysis of 32 histologically confirmed PBL cases.
- Data collected from three Tunisian medical oncology departments (1990-2014).
Main Results:
- Median age 53 years; predominantly large B-cell lymphoma affecting long bones, often diagnosed at early stages.
- 90% objective response to chemotherapy (CHOP/CHOP-like), with Rituximab used in recent cases.
- 5-year overall survival rate of 63%, with 14 patients in complete remission after a median follow-up of 38.5 months.
Conclusions:
- PBL is rare and often diagnosed late in Tunisia, but early stages are common.
- Chemotherapy (CT) and Rituximab demonstrate high efficacy, improving response and survival rates.
- Further research into optimal treatment strategies for PBL is warranted.

01:55Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:40Bone Remodeling
40.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:27Compact Bone
16.5K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:29Bone Disorders
5.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:12The Hyoid Bone
5.0K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

01:09Spongy Bone
7.9K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
