Bleeding, obstruction, and perforation in a series of patients with aggressive gastric lymphoma treated with primary chemotherapy.

BACKGROUND: The management of patients with gastric lymphoma has evolved, with a shift toward nonsurgical treatment. The rates of surgical complications in patients receiving chemotherapy have been insufficiently studied. The objective of this study was to assess the frequency of bleeding, perforation, and gastric outlet obstruction in patients who received chemotherapy as primary treatment for gastric diffuse large B cell lymphoma (DLBCL). METHODS: We reviewed files of all patients with gastric DLBCL who were diagnosed and treated primarily with chemotherapy in our hospital between 1990 and 2005. RESULTS: Eighteen (25%) of 73 patients experienced surgical complications, of whom 6 (8%) underwent surgery. Eight patients (11%), six with active lymphoma, experienced gastric bleeding; one required gastrectomy. Eight patients (11%) developed gastric outlet obstruction, of whom three were treated conservatively, three required surgery, one stopped treatment, and one received further chemotherapy. Six of the eight patients had no evidence of active lymphoma at the time of obstruction. Two additional patients underwent gastrectomy due to resistant or relapsed disease. Gastric perforation was not observed. Median survival was 90 months for the entire series, 94 months for patients with gastric outlet obstruction, and 11.5 months for patients with gastric bleeding. CONCLUSIONS: Given the rate of surgical complications, especially gastric bleeding and gastric outlet obstruction, there is still an important role for the surgical consultant in the treatment of patients with gastric DLBCL receiving chemotherapy. Gastric perforation, although frequently cited as a complication, is in fact rarely observed.

A new point-of-care method for monitoring anti-platelet therapy: application of the cone and plate(let) analyzer.

Recent studies suggest that anti-platelet agents are not equally effective in all individuals. We have developed a new method to evaluate the effect of anti-platelet drugs using the cone and plate(let) analyzer (CPA) test. The method is based on the ability of activators to reduce platelet adhesion under flow conditions. Treatment of a blood sample with arachidonic acid (AA) or ADP in vitro significantly decreased platelet deposition to a surface coverage (SC) of 2.1+/-0.4 and 1.3+/-0.6%, respectively, compared with the basic SC of 12.3+/-6.8%. The effect of AA was prevented by aspirin (SC 8.1+/-3.8%) and that of ADP was reduced by 2-methylthio-AMP, a P2Y12 ADP receptor inhibitor (SC 4.8+/-2.0%). Pre-incubation with AA of whole blood samples from untreated healthy volunteers resulted in a marked decline of SC (from SC 9.8+/-2.2 to 0.6+/-0.3%). In contrast, in volunteers treated with 100, 300, and 500 mg aspirin per day, AA (but not ADP) decreased SC only to 3.5+/-1.3, 4.4+/-1.7, and 4.1+/-2.0%, respectively (P<0.001 versus SC with AA before treatment). A good correlation was observed between the modified CPA and aggregometry (R2=0.55). In conclusion, the modified CPA test is a useful tool to evaluate the efficacy of anti-platelet therapy.

Prolonged fever of unknown origin and hemophagocytosis evolving into acute lymphoblastic leukemia.

Hemophagocytic syndrome (HPS) is an unusual acute syndrome presenting with fever, hepatosplenomegaly, and cytopenias. The hallmark of HPS is the accumulation of activated macrophages that engulf hematopoietic cells in the reticuloendothelial system. Most cases of HPS in adults are secondary to infection or malignancy, and thus investigation of the underlying disease is necessary. We describe a patient with prolonged fever, HPS, and chromosomal abnormalities in the bone marrow who underwent thorough evaluation for the cause of his symptoms. A final diagnosis of acute lymphoblastic leukemia (ALL) was established in a fourth, repeated bone marrow biopsy performed more than 2 months after the first presenting symptom appeared. This unusual case demonstrates the importance of cytogenetic abnormalities found in cases of HPS and the importance of repeated testing when an underlying disease is suspected.

Autoimmune cholangiopathy associated with systemic lupus erythematosus.

We report a 39-year-old female who presented over 11 years with autoimmune cholangiopathy associated with kaleidoscopic manifestations of systemic lupus erythematosus (SLE), including, arthritis, skin changes, pleuritis, diffuse proliferative glomerulonephritis, lymphadenopathy, splenomegaly, hyperglobulinemia, and major depression. While antimitochondrial antibodies (AMA) were absent, antinuclear (ANA) and anti-DNA antibodies were detected in high titres associated with hypocomplementemia. The patient also had vitamin B12 deficiency and antiphospholipid antibodies. The patient required steroids and repeated courses of cyclophosphamide for the management of lupus nephritis, and ursodeoxycholic acid (ursolite) administration resulted in amelioration of cholestatic laboratory abnormalities. This unusual case report and review of literature illustrate that immune liver disease may be an important clinical manifestation of SLE, especially autoimmune cholangiopathy.

Image-guided cutting-edge-needle biopsy of peripheral lymph nodes and superficial masses for the diagnosis of lymphoma.

OBJECTIVE: To evaluate the diagnostic efficacy of image-guided cutting-edge-needle biopsy of peripheral lymph nodes and superficial masses for the diagnosis of lymphoma, for which many still advocate open surgical resection. METHODS: A retrospective analysis was performed of the medical records of 114 lymphoma patients who presented with peripheral lymphadenopathy and superficial masses and who underwent diagnostic image-guided biopsy. There were 69 non-Hodgkin lymphoma patients, 38 Hodgkin lymphoma patients, and 7 patients who were evaluated for histologic transformation of CLL or high grade lymphoma. RESULTS: Image-guided needle biopsy was diagnostic in 96/114 (84.2%) patients. The procedure was diagnostic in 59/69 (85.5%) of NHL patients and in 30/38 of Hodgkin disease patients (79%). Diagnoses were achieved for all 7 cases where histologic transformation was suspected. CONCLUSION: Percutaneous image-guided needle biopsy is a safe and reliable procedure with a high diagnostic yield. It can be used as a first step in patients suspected of having lymphoma presenting with enlarged peripheral lymph nodes and superficial masses.
