Surgical treatment and pathological findings of hematological malignancies patients complicated with lung diseases / 中华血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To determine the pulmonary pathological changes in hematological malignancy patients with pulmonary complications.</p><p><b>METHODS</b>17 hematological malignancy patients underwent surgical treatment were evaluated retrospectively. The pathological changes of all the surgical specimens were examined postoperatively by standard hematoxylin and eosin (HE) staining.</p><p><b>RESULTS</b>Pathological examination confirmed: aspergillus infection in 9 patients, sub-acute inflammation (fibrosis and hematoma formation) in 3, and each in 1 of pulmonary infarction with granulomatous tissue in the periphery; granulomatous inflammation with calcified tubercle; alveolar dilation and hemorrhage, interstitial fibrosis and focal vasculitis; intercostal neurilemmoma; and moderate-differentiated adenocarcinoma accompanied by intrapulmonary metastasis. And several operative complications (1 case of fungal implantation, 3 pleural effusion and adhesions and 2 pulmonary hematoma) were occurred. The coincidence rate of pre- and post-operative diagnosis was 9/14 (64.3%). After surgery, 8 patients were received hematopoietic stem cell transplantation (HSCT, allo-gene or autologous), with 7 succeeded. On effective secondary antifungal prophylaxis, 4 of 5 patients of aspergillosis succeeded in transplantation with free from mycotic relapse, one patient died from fungal relapse.</p><p><b>CONCLUSION</b>Hematological malignancies with persistent and/or resistant pulmonary infection, hemoptysis, or unexplained lung diseases, should be treated in time by surgery operation to effectively eliminate residual disease and obtain a definitive diagnosis, so as to create a prerequisite condition for the following treatments. Moreover, the secondary antifungal prophylaxis can provide active roles for patients scheduled for chemotherapy and/or HSCT.</p>
