Eighteen patients with gastrointestinal and retroperitoneal non-Hodgkin's lymphoma received abdominal radiotherapy as their primary treatment. Each patient received a total tumor dose of 2200 to 4500 cGy in 5 to 9 weeks to the whole or half of one kidney. Nine patients developed unilateral radiation nephropathy demonstrable on post-treatment evaluation with 99m Tc glucoheptonate blood flow, delayed static scan, and an I-131 radio-hippurate renal perfusion study. The tests were periodically repeated over periods ranging from 5 to 8 years. Six patients with nephropathy and 4 patients without nephropathy were followed 5 years or longer. The minimum nephro-pathogenic irradiation dose was 2200 cGy delivered in 59 days. The incidence of nephropathy is higher with increase in the total dose. Short term recovery in function was observed in 3 patients and long-term complete recovery was observed in one patient. Atrophic renal change was irreversible and progressive in 3 patients over a 6 to 7 year follow-up period. In this group of patients, an abnormal creatinine clearance and serum beta-2 microglobulin level was indicative of vascular damage. Elevated arterial blood pressure was seen in 5 patients. All were controlled medically, without nephrectomy. There was no other clinically significant problem resulting from the unilateral nephropathy in this group of patients.

The levels of soluble interleukin-2 receptors (sIL-2R), beta-2 microglobulin (beta-2M), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured in the serum of 50 previously untreated patients with non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL) as well as in 25 age and sex-matched normal controls. Compared to normal controls, mean serum levels of sIL-2R and beta-2M were significantly increased in both NHL and CLL (p < 0.001) while the increase in ESR and CRP was less marked (p < 0.01 and p < 0.05, respectively). Comparison of these tumor markers with histologic grading showed statistically significant differences only for CRP between low, intermediate and high-grade lymphomas (p < 0.001 and p < 0.05). More advanced stages exhibited higher mean values of all serum markers than early stages (p < 0.001 for sIL-2R, beta-2M and ESR and p < 0.05 for CRP). An association with the presence of b-symptoms was observed only for sIL-2R (p < 0.05). In addition, sIL-2R as well as beta-2M were able to predict time to progression in patients with diffuse large-cell lymphomas. We conclude that of the four tumor markers tested sIL-2R and beta-2M more frequently showed increased serum levels and were associated with clinical stage and/or presence of b-symptoms. Both sIL-2R and beta-2M were also found to have prognostic significance for survival.

Serum levels of sICAM-1, sIL-2alphaR, and beta-2 microglobulin were measured in 63 patients with non-Hodgkin's lymphoma (NHL). The correlation between these serum markers as well as their relationship with NHL features and disease outcome were analyzed. Although in high-grade NHL sICAM-1 levels correlated with tumor mass, no correlation was found between sICAM-1 levels and tumor burden in low-grade NHL. When compared with sICAM-1 and beta-2 microglobulin, sIL-2alphaR showed the strongest correlation with the tumor burden. However, in multivariate analysis, including serum markers employed as continuous variables, the only parameteres which entered the regression model were beta-2 microglobulin (p=0.012) and sICAM-1 (p=0.019). In a dichotomized model, beta-2 microglobulin, aggressive histology, sICAM-1, age and number of nodal involved sites were found to be prognostically significant. Finally, by combining sICAM-1 and beta-2 microglobulin serum levels, a simple prognostic model useful for NHL was obtained.

Plasma levels of beta-2 microglobulin (beta2M), a subunit of the human leukocyte antigen-class I (HLA-I) molecule, correlate negatively with outcome in non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD). We examined the clinical relevance of soluble HLA-I (sHLA-I) levels in NHL and HD. Sera from consecutive NHL (n=65) and HD (n=37) patients were analyzed in a blinded manner. NHL and HD patients had significantly higher levels of sHLA-1 and beta2M than control subjects. In NHL patients, sHLA-I levels correlated with clinical behavior in a fashion similar to that of beta2M. However, multivariate analysis incorporating beta2M, sHLA-I, and international prognostic index (IPI) indicated that NHL patients with elevated (>312.6mug/100mL) sHLA-I levels had significantly shorter survival, independent of IPI score as well as beta2M. In HD patients, beta2M but not sHLA-I levels were associated with clinical behavior. These findings not only establish the role of sHLA-I as an independent tumor marker in NHL that can be used to stratify patients, but also suggest that beta2M and sHLA-I may reflect different biological processes in HD and NHL. Further studies are needed to assess whether the immunomodulatory properties of sHLA-I may be responsible for its divergence from beta2M as an indicator of clinical behavior in HD.

This study sought to identify risk factors for early death in non-Hodgkin's lymphoma (NHL). The databases of a tertiary medical center were reviewed for adult patients diagnosed with NHL since 1985 who died within 4 months of diagnosis. Comprehensive background, disease-related data, and treatment-related data were collected and analyzed by descriptive statistics. Ninety-two patients (7 % of the patient registry) met the inclusion criteria: 40 men and 52 women of mean age 74 years. Most (86 %) had B cell NHL; the most frequent pathologic classification was diffuse large B cell lymphoma (75 %). Rates of other disease-related factors were as follows: aggressive disease, 90 %; stage IV, 73 %; bulky disease, 66 %; extranodal involvement, 86 % (usually >1 site); performance score 2-4, 76 %; international prognostic index 3-5, 89 %; and B symptoms, 84 %. Mean Ki-67 proliferation index was 71 %. Additionally, 80 % of patients had a high lactose dehydrogenase level, 89 % a high beta-2 microglobulin level, and 47 % serosal (mainly pleural) effusion. A history of other cancer or organ transplantation was documented in 24 %. Chemotherapy was administered to 59 %, mostly CHOP. In conclusion, early death occurs in at least 7 % of patients with newly diagnosed NHL. This patient group is characterized by older age, aggressive lymphoma, poor performance status, advanced-stage disease, extranodal disease, B symptoms, bulky disease, elevated lactate dehydrogenase and beta-2 microglobulin levels, and serosal effusion. These early death resulted from sepsis, severe underlying disease, disease progression, or gastrointestinal perforation. The selection of appropriate treatment modalities for these patients with poor prognostic features is a real challenge. They should undergo comprehensive geriatric assessment and receive individualized tailored treatments with protocol adjustment to their condition, strict clinical surveillance, best supportive care, and maybe, as recently suggested, a prephase treatment.
