In a study of non-Hodgkin's lymphoma in children, 104 children were treated and followed at Memorial Sloan-Kettering Cancer Center from 1964 throughout June 1974. Forty-three patients, previously treated and untreated, received a nonspecific group of various chemotherapeutic agents and attained an 11% disease-free survival rate. A second group of 18 previously untreated patients, who received a chemotherapeutic regimen consisting of cyclophosphamide alone, achieved a 33% disease-free survival rate. The last group, 43 previously untreated patients (77% of whom had far advanced disease and 86% of whom had diffuse histological types) who received a new and intensive multiple-drug regimen (the LSA2-L2 protocol) consisting of induction, consolidation, and maintenance phases, has maintained an 81% disease-free survival rate after a median observation time of 21+ months. Although nervous system involvement and recurrence or metastases at any time are poor prognostic factors, initial marrow involvement and the amount of bulky disease are no longer considered negative prognosticators when intensive treatment is initiated immediately after diagnosis, is continued for 2--3 years, and includes radiation therapy to sites of bulky disease and CNS prophylaxis. The LS2-L2 treatment is effective in accomplishing the dual aims of not only increasing the numbers of disease-free patients but also prolonging their survival.

Activation of prothrombin and the subsequent reactions of thrombin with its substrates and its major inhibitors, antithrombin III (AT III) and heparin cofactor II (HC II), likely reflect both intravascular and extravascular coagulation. Several studies have reported increased in vivo coagulation in cancer. Whether the increased thrombin production in malignancy is accompanied by a corresponding increase in thrombin inhibition is unknown. This study quantified prothrombin fragment 1 + 2 (F1 + 2), thrombin-AT III (TAT), thrombin-AT III-vitronectin (TAT.V), and thrombin-HC II-vitronectin (THCII.V) in the plasmas of healthy volunteers (n = 37); patients with localized solid tumours before treatment was initiated (n = 39); and five patients with non-Hodgkin's lymphoma, both before and during weekly chemotherapy. Two of the five non-Hodgkin's lymphoma patients developed deep venous thrombosis (DVT) during chemotherapy. In normal plasma, where the concentrations of the four parameters likely reflect haemostasis, the sum of TAT, TAT.V and THCII.V was 61% that of F1 + 2, compared with 30% in cancer plasmas. In addition, the mean +/- SEM of F1 + 2 in the plasmas of cancer patients (1.56 +/- 0.09 nM) was significantly elevated (P < 0.001) when compared with healthy volunteers (0.89 +/- 0.06 nM). Eight weeks of chemotherapy increased the F1 + 2 and the binary TAT in plasmas of the non-Hodgkin's lymphoma patients by approximately 1.5- and 2.9-fold, respectively. Thus, increased prothrombin activation in cancer patients, without corresponding increases in concentrations of thrombin-inhibitor complexes, raise the possibility that a significant portion of the thrombin generated in vivo escapes inhibition in cancer and contributes to the high risk of DVT in malignancy.
