To define the incidence and spectrum of pulmonary complications following autologous bone marrow transplantation (BMT), we retrospectively reviewed the course of 77 consecutive patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) who failed conventional therapy and underwent autologous BMT. Forty-five percent of the 77 patients developed respiratory complications with a mortality from pulmonary causes of 26%. A total of 38 episodes of respiratory compromise occurred in 35 patients. Infections accounted for 15 episodes (39%) and included bacterial (16%), Aspergillus (8%) cytomegalovirus (8%), Herpes simplex (3%), and other (5%) pneumonias. The spectrum of infections was similar to that reported following allogeneic BMT, but cytomegalovirus pneumonia was not as frequent a problem in those with autologous transplant. Mortality from pulmonary infections was 33%. Noninfectious disorders accounted for 23 episodes (61%) and included recurrent HD (18%), radiation/drug toxicity (16%), and acute respiratory failure thought secondary to pulmonary alveolar hemorrhage (26%). This latter entity developed acutely within 2 wk following BMT and was associated with use of thoracic radiation for treatment of malignant disease in the chest just prior to BMT (p < 0.05). It was not associated with the age of the patient or presence of thrombocytopenia, coagulopathy, renal insufficiency or neutropenia (p NS). Mortality from noninfectious causes was 65%, but in those with pulmonary hemorrhage it was 100%. In conclusion, pulmonary complications are a major source of morbidity and mortality in patients with HD and NHL undergoing autologous BMT.(ABSTRACT TRUNCATED AT 250 WORDS)

A 24-year-old man had a large anterior mediastinal mass and a nonproductive cough of 6 weeks' duration. With the patient under general anesthesia, a diagnostic mediastinoscopy was performed with endotracheal intubation. During the procedure, acute respiratory failure developed as a result of tracheal obstruction. Fiberoptic bronchoscopic examination of the patient in the supine position revealed almost total extrinsic compression of the trachea and no evidence of intraluminal disease. Reexamination of the trachea with the patient in sitting and semiprone positions showed resolution of the extrinsic compression and respiratory distress. Flow-volume curves obtained before treatment of the mediastinal mass (histologically diagnosed as Hodgkin's lymphoma) disclosed major airway compression with the patient in the supine position; the abnormality disappeared after chemotherapy. The mechanisms responsible for tracheal compression by mediastinal masses during general anesthesia may include the following: (1) the effect of anesthesia on pulmonary mechanics, (2) the supine body position, (3) the elimination of glottic regulation of airflow by endotracheal intubation, (4) changes related to the surgical manipulation of the tumor itself, (5) the size and location of the mediastinal mass, (6) the young age of the patient, and (7) preexisting airways disease. Anticipation and prevention of potential respiratory complications and preparedness to treat them appropriately are important aspects of the management of these patients.

In an effort to improve the treatment of patients with refractory or recurrent lymphoma, we developed a protocol using cis-platinum combined with two other agents of known efficacy in these disorders but with differing side effects: VP-16 and MGBG. Twenty-six eligible patients were treated with this regimen. There were 15 men and 11 women with a median age of 54 years (22-73), and performance status of 1 (0-3). Their diagnoses were Hodgkin's disease 5 and non-Hodgkin's lymphoma [NHL] 21 which included 11 with diffuse histocytic lymphoma [DHL]. The median number of chemotherapy regimens was 2 (1-5); 12 also received radiotherapy. Twenty patients are evaluable for response: 15 NHL and 5 Hodgkin's disease. Three patients, all of whom had DHL entered complete remission (20%) with a median time to treatment failure of 7 1/2 months. Six NHL (40%) and one Hodgkin's disease (20%) patients entered a partial remission. There were three early deaths: one due to progressive disease, one to acute respiratory failure, and one with disease status undocumented. Toxicity included leukopenia, thrombocytopenia, anorexia, nausea, vomiting, stomatitis, alopecia, renal failure, profound peripheral neuropathy, and hypersensitivity vasculitis. Treatment was stopped because of the latter two. These agents are non-crossresistant with doxorubicin-containing regimens. The drugs are possibly synergistic and modestly active with moderate to severe toxicity.

In total 19 cases of non-Hodgkin lymphoma originating from the wall of chronic tuberculous empyema, pleuropneumonectomeic were performed since 1979, with the aim of total cures for not only lymphoma but empyema in 11 cases. Of these cases extraresections (5 of thoracic cages, 4 of diaphragms, 2 of axillar lymph nodes, each of adventitia of descending aorta and esophagus, of the liver, of the left adrenal grand) were added to extirpate tumors completely. The mean operating time was 6 degrees 55', the mean blood loss during operations was 3090 ml, but in the 3 most recent cases it was less than under 1000 ml using electrocartesy-cutting technique under direct observation. Although preoperative radiations were done to 4 cases to decrease invasive area of tumors and postoperative radiation was done to 1 case, there were no adjuvant chemotherapies. The indicative limitation for resections from the point of ventilatory functions was the same as that of pleuropneumonectomy for ordinary chronic tuberculous empyema. There were 2 cases with serious postoperative complications. One suffered from ARDS and died on the 14th postoperative day, and another developed acute respiratory failure and MOF. But the other 9 cases kept good postoperative courses with a few recurrences of minor empyema. The prognoses for 10 remaining cases is excellent. Only one case died from local recurrence in of lymphoma 27 months later, but all other 9 cases have revealed no recurrence in any places, and the 5 year survival rate based on Kaplan-Meier method of 10 cases is 85.7%. By the way no cases could survive one year later in unresected group. So under the poor prognosis of treatment with radiation or chemotherapy for non-Hodgkin lymphoma originating from chronic tuberculous empyema, we conclude that the complete resection of tumor and empyema, so called pleuropneumonectomy, is the best way to cure this disease.

Inactivation of the INK4a/ARF locus is a frequent event in non-Hodgkin's lymphomas (NHLs), which may be attributed to deletion, point mutation, and 5' CpG methylation at its promoter region. In the present study we evaluated the occurrence of deletions and genetic instability of INK4a/ARF locus in 30 paired normal and tumor samples of B cell NHLs by conducting an allelotypic analysis with two new polymorphic markers, one located at the intron 1 of p16INK4a gene and the other one placed downstream exon 1beta of p19ARF. Comparison of these results with those obtained in a previous paper using flanking markers (D9S171, D9S942, D9S958 and IFNA) allowed us to detect two new cases of microsatellite instability (L-446 and L-442), and to confirm the occurrence of LOH at the INK4a/ARF locus in one tumor (M-3770). On the contrary, this locus is not affected in three different tumors (L-421, L-272 and L-159) which exhibited LOH at some of the flanking markers.

Chronic B-cell lymphocytic leukaemia (CLL) and low-grade B-cell Non Hodgkin's lymphomas (Lg-NHL) are characterized by slow accumulation of neoplastic cells arrested in the G0/G1 phase of the cell cycle. In contrast, proliferation rates are high in aggressive B-cell lymphomas (Hg-NHL). Divergent expression of cyclin-dependent kinase inhibitors (CKI) in the cell cycle may contribute to these differences. We analysed CLL as well as low and high grade B-cell NHL for expression of G1-specific and universal CKI by competitive RT-PCR and immunostaining. p16(INK4A) expression was low in all types of neoplasms. Highest p14(ARF) /p16 beta expression levels were found in normal lymphocytes. Expression of this CKI was significantly lower in CLL, but still higher in CLL than in the lymphomas (median 27 vs. 3 mRNA transcripts x 10(3), p = 0.0001). p14(ARF) /p16 beta immunostaining correlated with mRNA expression. Highest p21 mRNA levels were found in CLL, but three of four CLL with abundant p21 mRNA production were negative on immunostaining. High grade lymphomas showed markedly decreased p21 expression (3.9 in Hg-NHL vs. 12 in Lg-NHL and 29 in CLL; values expressed as mRNA transcripts x 10(3), p < 0.009). mRNA and protein expression of p27 was considerably higher in CLL than in the lymphomas. Differential CKI expression in various B-cell neoplasias may provide important biological markers, if not the molecular underpinning of their different cell cycle kinetics. Targeted interference with such genes governing cell cycle control in lymphoid neoplasia may pave the way towards new treatment strategies.

The BMI-1 gene is a putative oncogene belonging to the Polycomb group family that cooperates with c-myc in the generation of mouse lymphomas and seems to participate in cell cycle regulation and senescence by acting as a transcriptional repressor of the INK4a/ARF locus. The BMI-1 gene has been located on chromosome 10p13, a region involved in chromosomal translocations in infant leukemias, and amplified in occasional non-Hodgkin's lymphomas (NHLs) and solid tumors. To determine the possible alterations of this gene in human malignancies, we have examined 160 lymphoproliferative disorders, 13 myeloid leukemias, and 89 carcinomas by Southern blot analysis and detected BMI-1 gene amplification (3- to 7-fold) in 4 of 36 (11%) mantle cell lymphomas (MCLs) with no alterations in the INK4a/ARF locus. BMI-1 and p16INK4a mRNA and protein expression were also studied by real-time quantitative reverse transcription-PCR and Western blot, respectively, in a subset of NHLs. BMI-1 expression was significantly higher in chronic lymphocytic leukemia and MCL than in follicular lymphoma and large B cell lymphoma. The four tumors with gene amplification showed significantly higher mRNA levels than other MCLs and NHLs with the BMI-1 gene in germline configuration. Five additional MCLs also showed very high mRNA levels without gene amplification. A good correlation between BMI-1 mRNA levels and protein expression was observed in all types of lymphomas. No relationship was detected between BMI-1 and p16INK4a mRNA levels. These findings suggest that BMI-1 gene alterations in human neoplasms are uncommon, but they may contribute to the pathogenesis in a subset of malignant lymphomas, particularly of mantle cell type.

Recently, comparative genomic hybridization (CGH)- and fluorescence in situ hybridization (FISH)-analyses of native Hodgkin and Reed-Sternberg (H&RS) cells extracted from Hodgkin lymphoma (HL) revealed a recurrent amplification of the HDM2 locus on chromosome 12. HDM2 is known to target, inactivate and to degrade p53. Wild type (wt) p53 protein is detected in high levels in HL. Simultaneously, stabilized wt p53 and spliced hdm2 transcripts have been observed in different tumors. Therefore, we examined the expression and structure of HDM2 in HL cell lines and possible effects on components of the p53 pathway. DNA integrity and induction potential of p53 was verified by DNA sequencing and detection of potential effector proteins (p21(WAF/CIP), HDM2) using immunofluorescence, respectively. All HL cell lines show an overexpression of HDM2 protein. Furthermore, several different spliced hdm2 transcripts (mdm-sv) including five new variants lacking a functional p53 binding site were characterized. If expressed, corresponding proteins were shown to be not restricted to the nucleus. Co-localization of the potential binding partners HDM2/p14(ARF) and HDM2/p53 was found in HL cell lines. We suggest that HDM2-sv have no significant disturbing influence on the interaction of these proteins.

The beneficial role of corticosteroid therapy for the treatment of methotrexate-induced pneumonia remains controversial. We report two cases of acute severe interstitial pneumonia induced by methotrexate in patients with non-Hodgkin lymphoma given a polychemotherapy protocol (M'BACOD). The first signs appeared on the eleventh day of the first cycle in patient one and on the tenth day of the third cycle in patient two. The causal implication of methotrexate was based on the history, the clinical and radiological presentation, and the negative tests in both patients: lymphocyte alveolitis with granulomatous lesions on the transbronchial biopsy in patient one and positive leukocyte migration test in the presence of methotrexate in patient two. Early acute respiratory failure required high flow rate oxygen therapy with positive expiratory pressure ventilatory assistance. The course was rapidly favorable both for blood gases and radiographic presentation without corticosteroids. These two cases illustrate that pulmonary disease can be cured without corticosteroids despite severe respiratory failure at onset. This provides a further argument on reservations about using corticosteroids for suspected methotrexate-induced pneumonia.

Paraneoplastic neurologic syndromes associated with Hodgkin's lymphoma include the stiff-person syndrome. A case of stiff-person syndrome is reported who first presented with muscular hyperactivity and acute respiratory failure followed by heterotopic soft tissue ossification and acute seronegative gonarthitis. Initial improvement of a tetanus-like clinical picture was achieved with benzodiazepam given by continuous infusion for analgo-sedation to mechanically ventilate the patient followed by baclofen after successful weaning. The patient was HLA B27 positive and on conventional testing no autoantibodies were detected including anti-glutamic acid decarboxylase antibodies (anti-GAD). Months later in the absence of signs of stiff-person syndrome, mediastinal lymphadenopathy and pleural effusions developed which were diagnosed as classical Hodgkin's lymphoma that was successfully treated with polychemotherapy. No relapse of paraneoplastic neurologic syndromes was seen after two years of lymphoma remission. The case illustrates that stiff-person syndrome may precede the clinical appearance of symptomatic Hodgkin's lymphoma.
