Quality of life assessment in patients with metastatic colorectal cancer receiving maintenance therapy after first-line induction treatment: a preplanned analysis of the phase III AIO KRK 0207 trial.

BACKGROUND: First-line maintenance strategies are a current matter of debate in the management of mCRC. Their impact on patient's health-related quality of life (HRQOL) has not yet been evaluated. The objective of this study was to assess whether differences in HRQOL during any active maintenance treatment compared with no maintenance treatment exist. PATIENT AND METHODS: Eight hundred and thirty-seven patients were enrolled in the AIO KRK 0207 trial. Four hundred and seventy-two underwent randomization (after 24 weeks of induction treatment) into one of the maintenance arms: FP plus Bev (arm A), Bev alone (arm B), or no active treatment (arm C). HRQOL were assessed every 6 weeks during induction and maintenance treatment independent from treatment stop, delay, or modification, and also continued after progression, using the EORTC QLQ-C30, QLQ-CR29. The mean value of the global quality of life dimension (GHS/QoL) of the EORTC QLQ-C30, calculated as the average of all available time points after randomization was considered as pre-specified main endpoint. Additionally, EORTC QLQ-C30 response scores were analyzed. RESULTS: For HRQOL analysis, 413 patients were eligible (arm A: 136; arm B: 142, arm C: 135). Compliance rate with the HRQOL questionnaires was 95% at time of randomization and remained high during maintenance (98%, 99%, 97% and 97% at week 6, 12, 18 and 24). No significant differences between treatment arms in the mean GHS/QoL scores were observed at any time point. Also, rates of GHS/QoL score deterioration were similar (20.5%; 17.2% and 20.7% of patients), whereas a score improvement occurred in 36.1%; 43.8% and 42.1% (arms A, B and C). CONCLUSION: Continuation of an active maintenance treatment with FP/Bev after induction treatment was neither associated with a detrimental effect on GHS/QoL scores when compared with both, less active treatment with Bev alone or no active treatment.

Mixed malignant germ cell tumour of the liver.

Germ cell tumours of the liver are rare neoplasms, with fewer than 20 cases reported in the literature following presentation as teratomas, choriocarcinomas or yolk sac tumours. We report a 52-year-old patient who complained of upper abdominal pain and anorexia. Ultrasonography and computed tomography of the abdomen revealed a large hepatic mass. Among the laboratory values we found elevated levels of alpha-fetoprotein and beta-chorionic gonadotropin. Repeated biopsies via CT scan, laparoscopy and laparotomy disclosed a poorly differentiated adenocarcinoma. Subsequently liver function deteriorated and, on the basis of clinical data highly suggestive of a malignant germ cell tumour, a modified chemotherapeutic protocol (PEI) was initiated. The elevated levels of alpha-fetoprotein and beta-chorionic gonadotropin declined rapidly, but the patient died 10 days later of liver dysfunction and bronchopneumonia. Subsequent autopsy confirmed the initial clinical diagnosis of a multilocular extragonadal malignant germ cell tumour of the liver with components of choriocarcinoma and embryonal carcinoma.

Chemotherapy with cisplatin and paclitaxel in patients with locally advanced, recurrent or metastatic oesophageal cancer.

Single-agent therapy with paclitaxel is effective against both squamous cell carcinoma and adenocarcinoma of the oesophagus. However, only limited data are available on the combination of paclitaxel with other cytotoxic drugs in this entity. Patients with unresectable stage III, recurrent or metastatic tumours were treated in a multicentre setting with paclitaxel 90 mg m(-2) given over 3 h intravenously, followed by cisplatin 50 mg m(-2). The courses were repeated every 14 days. Twenty patients with squamous cell carcinoma or adenocarcinoma of the oesophagus were evaluable for response. The overall remission rate was 40% (8/20), including 15% (3/20) clinically complete responses. Clinical benefit response, defined as relief of dysphagia and/or significant gain in weight, was achieved in 70% of the patients. Neutropenia of CTC grade 3 occurred only in 10% of the patients; no grade 4 neutropenia and no severe thrombocytopenia was encountered. CTC grade 4 neurotoxicity was seen in 5% of patients. Cisplatin/paclitaxel administered every 14 days, was effective in patients with poor prognosis oesophageal cancer and toxicity was acceptable.

Antibody responses of splenectomized patients with non-Hodgkin's lymphoma to immunization with polyvalent pneumococcal vaccines.

The serum antibody responses of splenectomized patients with non-Hodgkin's lymphoma (NHL) who had been immunized with a polyvalent pneumococcal vaccine (Pneumovax 23) were evaluated by an enzyme-linked immunosorbent assay with the 23-valent pneumococcal vaccine as the antigen. A response to immunization, defined as a twofold-or-higher rise of the prevaccination titer of antibodies against Streptococcus pneumoniae polysaccharide, was elicited in 5 of 11 patients with NHL. No significant difference in the level of antibodies against S. pneumoniae polysaccharide between lymphoma patients and patients who had undergone splenectomy for other reasons was detected (P = 0.83 and 0.87 before and after vaccination, respectively). NHL patients who did not respond to the first immunization received a booster dose of the polysaccharide vaccine. This injection did not increase the pneumococcal-antibody titer significantly (P = 0.7). We conclude that vaccination with pneumococcal polysaccharides in splenectomized patients with NHL elicits an adequate antibody response in 45.4% of the cases and should therefore be administered. Revaccination of the nonresponders does not further increase the pneumococcal-antibody levels.
