Monoclonal antibody assay of serum placental alkaline phosphatase in the monitoring of testicular tumours.

A monoclonal antibody (H17E2) recognising both placental alkaline phosphatase (PLAP) and testicular PLAP-like alkaline phosphatase was incorporated in a solid phase immunoassay. This was used to measure levels of PLAP in 257 sera from 148 patients with germ cell neoplasms of the testis. High levels of PLAP were found in all patients with active seminomas (mean 0.85 O.D.) compared to those in clinical remission (mean 0.20 O.D.) (P less than 0.0001). More importantly, changing levels of PLAP correlated with the course of disease in 79 samples from 33 patients with seminoma (P less than 0.0001). Elevated PLAP levels were also noted in patients in remission who were smokers (mean 0.32 O.D.) compared to non-smokers (mean 0.15 O.D.) (P less than 0.001). These data demonstrate that determination of PLAP levels using this sensitive immunoassay is an important new adjunct in the monitoring of the response to treatment in patients with seminoma.

The treatment of stage IIIA Hodgkin's disease.

Sixty consecutive previously untreated adults with surgically confirmed stage IIIA Hodgkin's disease (39 stage IIIA1, 21 stage IIIA2) began therapy at St. Bartholomew's Hospital between 1969 and 1981. Prior to 1973, treatment consisted of total nodal irradiation (TNI). From 1973 until 1978 patients were randomly allocated to receive either TNI or cyclic combination chemotherapy of mustine, vinblastine, prednisolone, and procarbazine (MVPP) as part of a Medical Research Council Trial. Since 1978 treatment has been allocated according to substage, those with stage IIIA1 receiving TNI and those with stage IIIA2 receiving MVPP. Seven patients received "non protocol" therapy (extended mantle radiotherapy in three patients, mantle and MVPP in four patients), and have been excluded from the study. Complete remission was achieved in 48 of 53 patients regardless of substage or therapy. Seven have relapsed, one after MVPP and six after TNI. The predicted freedom-from-relapse after MVPP was 96% compared with 60% after TNI, both at 10 years (p less than 0.01). The relapse pattern was the same for both substages in the group receiving TNI. Although overall survival of patients receiving TNI was identical to that of those receiving MVPP, TNI must be considered inappropriate therapy for stage IIIA Hodgkin's disease if permanent freedom-from-recurrence is the goal.

Biosensor-based micro-affinity purification for the proteomic analysis of protein complexes.

A biosensor-based micro-affinity purification method to recover protein binding partners and their complexes for down stream proteomics analysis has been developed using the BIAcore 3000 fitted with a prototype Surface Prep Unit (SPU). The recombinant GST-intracellular domain of E-cadherin or the recombinant GST-beta-catenin binding domain of Adenomatous Polyposis Coli (APC) were immobilized onto the SPU and used to affinity purify binding partners from chromatographically enriched SW480 colon cancer cell lysates. A GST- immobilized surface was used as a control. Samples recovered from the SPU were subjected to SDS-PAGE with sensitive Coomassie staining followed by automated in-gel digestion and LC-MS/MS. The results obtained using the SPU were compared with similar experiments performed using Sepharose beads.
