OBJECTIVETo study the clinicopathologic features of intravascular large B-cell lymphoma (IVLBCL).

METHODSTwo autopsy cases of IVLBCL were retrieved from the archival file. The clinicopathologic features, immunohistochemistry and molecular findings were studied.

RESULTSThe deceased were 70-year-old and 50-year-old males. Both of them had complained of a sudden onset of weakness and numbness of lower extremities. The clinical course deteriorated rapidly, with multi-organ failure. They died 85 days and 44 days after the presentation, respectively. Post-mortem examination did not reveal any mass lesion, except the presence of multiple skin and epicardium nodules, ranging from 0.5 cm to 2.5 cm in diameter, in the first patient. Pericardial effusion, ascites and pleural effusion were also observed. Histologically, neoplastic lymphoid cells filled up the small vessel lumina in many organs, including brain, hypophysis, spinal cord, spinal nerve roots, heart, lungs, kidneys, liver, spleen, digestive tract, pancreas, adrenal, thyroid, testes and lymph nodes. The tumor cells were relatively monotonous and of medium to large in size with round vesicular nuclei and 1 to 3 small basophilic nucleoli. Immunohistochemical study showed that the lymphoma cells expressed B-cell markers CD20 and CD79a, occasionally positive for CD5 and bcl-2 but negative for CD3, bcl-6, CD10, CD30, myeloperoxidase and cytokeratin. In-situ hybridization for Epstein-Barr virus-encoded RNA was negative. The proliferative index, as demonstrated by Ki-67 staining, was about 80%. Molecular study showed the presence of immunoglobulin heavy chain gene rearrangement in both cases, T-cell receptor-gamma gene rearrangement was not found.

CONCLUSIONSIVLBCL may present as neurological disturbance and carries distinctive morphologic characteristics, immunophenotype and molecular findings. The prognosis of this disease is often dismal.

OBJECTIVETo explore and evaluate the application of epiglottis with sternohyoid muscle in the surgery for laryngeal cancer.

METHODSTwo fifty patients with laryngeal cancer were treated by partial laryngectomy and the laryngeal defects were reconstructed by epiglottic flap and sternohyoid muscle fascia flap. The staging of tumors: T2N0M0 23 cases, T3N1M0 14 cases, T3N2M0 13 cases. All of them received post radical radiotherapy with average 60 Gy. The patients were followed up for 3 to 5 years. Thirty patients underwent neck dissection.

RESULTSThe three and five years survival rates were 90% and 80% respectively. The total cases eat breath pronounced well. The decannulation rate was 96%.

CONCLUSIONAfter partial laryngectomy in laryngeal cancer epiglottic flap and sternohyoid muscle fascia flap were performed reconstruction of laryngeal function.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.
