RESUMEN
Objective@#To investigate the characteristics in pathological diagnosis, clinical features, treatment and prognosis of adult patients with pediatric-type follicular lymphoma (PTFL) .@*Methods@#The clinical and pathological features, laboratory examination, diagnosis and treatment, follow-up results of 5 adult PTFL patients admitted in Jiangsu Province Hospital were retrospectively analyzed, and literature review was conducted in combination with related reports.@*Results@#All 5 patients developed PTFL in their adulthood with a median age of 22 years old (15-33 years) . The initial inanifestation of the disease was local painless lymphadenopathy with no fever, night sweats, emaciation or other systemic B symptoms. Pathological characteristics including typical large follicular structures and high proliferation index were found. Meanwhile, additional clonal rearrangement of immunoglobulin heavy chain gene was observed. However, there was no BCL-2 expression in histochemistry as well as BCL-2 gene abnormality in fluorescence in situ hybridization among these PTFL patients. These adult PTFL patients were all in stage Ⅰ-Ⅱ of the disease. For treatment, they were only treated with local surgical excision after diagnosis while didn’t receive subsequent local radiotherapy or systemic immunochemotherapy. During a median follow-up of 27 months, the 5 cases of PTFL kept in a state of sustained complete remission.@*Conclusion@#Adult-onset PTFL is characterized by high pathological proliferation index, while no BCL-2 expression or BCL-2 gene abnormality. Besides, PTFL is clinically manifested as a localized disease that can achieve a quite good prognosis through local surgical intervention. The aforementioned attributes of PTFL are distinctly different from classic adult follicular lymphoma.
RESUMEN
Marginal zone lymphoma (MZL) accounts for approximately 10 % of non-Hodgkin lymphoma (NHL). It can be divided into three specific entities:extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), nodal marginal zone lymphoma (NMZL) and splenic marginal zone lymphoma (SMZL). MALT lymphoma is the most frequent overall, representing 7.5 % of all NHLs. Reports on research progress of MZL in the 58th American Society of Hematology Annual Meeting covered multiple respects which ranged from basic research to clinical prognosis and treatment. Based on the technology such as flow cytometry, cytogenetics and FISH, further study on pathogenesis of MZL is developing, and new prognostic index system can help to stratify patients more exactly and give a guidance to treatment. What's more, the change of therapy and new drugs will benefit to the clinical efficacy and safety of MZL patients.
RESUMEN
Objective To investigate the diagnosis and treatment of primary hyperparathyroidism ( PHPT) initially with urinary calculus .Methods The clinical data of 26 patients who diagnosed as PHPT ini-tially with urinary calculus were retrospectively reviewed .Results There were 22 cases with bilateral urinary calculus and 4 cases with unilateral relapsed urinary calculus .Ultrasonography , CT and radionuclide were helpful to determine the location of the neoplasia .24 cases underwent percutaneous nephroscope or ureteroscopy pneu-matic ballistic lithotripsy , 2 cases discharged ureteral calculi by themselves .All patients were performed surgical treatment of PHPT , which was confirmed by intraoperative frozen pathology and postoperative pathological exami -nation.There was great improvement of clinical symptoms after surgical procedures .The preoperative serum calci-um, urine calcium and parathyroid hormone elevated , while serum phosphate decreased .The postoperative indi-cators were just the opposite .The difference had statistical significance ( P<0.05 ) .Conclusions Laboratory investigations and imaging studies are very important to diagnose PHPT initially with urinary calculus .The para-thyroid surgery can remarkably reduce the calculus recurrence and improve renal function .
