چکیده

The effects of chemotherapy were evaluated in 43 multiple myeloma patients with high monoclonal globulin levels in both serum and urine. In responding patients, Bence Jones protein excretion declined more rapidly and markedly than the serum myeloma protein. Bence Jones protein excretion was reduced by 50% within 2 mo in responders, remained unchanged in nonresponders, and declined with a slow halving time of 2-7 mo in patients with partial disease control. Three patients with clinical resistance to treatment showed atypical protein changes and progressively more Bence Jones protein excretion relative to their serum monoclonal component. Serial measurements of Bence Jones protein excretion provided an early and reliable index of tumor mass change in patients with multiple myeloma.

Expansion of the growth fraction in multiple myeloma with alkylating agents.

Patients with IgG multiple myeloma underwent serial studies of tumor cell kinetics including (1) estimation of the total body myeloma cell number (TBMC), (2) measurement of the myeloma cell tritiated thymidine labeling index (LI), and (3) calculation of the total number of myeloma cells undergoing DNA synthesis. Intermittent courses of chemotherapy with cycle-non-specific agents such as melphal...

Autophagy induced by conventional chemotherapy mediates tumor cell sensitivity to immunotherapy.

Autophagy attenuates the efficacy of conventional chemotherapy but its effects on immunotherapy have been little studied. Here, we report that chemotherapy renders tumor cells more susceptible to lysis by CTL in vivo. Moreover, bystander tumor cells that did not express antigen were killed by CTL. This effect was mediated by transient but dramatic upregulation of the mannose-6-phosphate recepto...

Timed sequential chemotherapy of cytoxan-refractory multiple myeloma with cytoxan and adriamycin based on induced tumor proliferation.

Malignant plasma cell proliferation and induced humoral stimulatory activity (HSA) occur in vivo at a predictable time following drug administration. Sequential sera from 11 patients with poor-risk multiple myeloma (MM) undergoing treatment with Cytoxan (CY) 2400 mq/sq m were assayed for their in vitro effects on malignant bone marrow plasma cell tritiated thymidine (3HTdR) incorporation. Peak ...

Kinetics of Synthesis and Secretion of [3h]leucine-, [3h]galactose- and [3h]mannose-labelled Myeloma Protein by Two Plasma-cell Tumours by Fritz Melchers

The kinetics of incorporation of leucine, galactose and mannose into intracellular and secreted myeloma protein, MOPC 21 IgG, and MOPC 46 K-type light chain, by cell suspensions of two myeloma plasma-cell tumours, MOPC 21 and MOPC 46, were similar. Radioactive galactose was incorporated to over 90% into galactose residues ofintracellular and secreted protein, mannose to over 90% into glucosamin...
