Introduction: We conducted a feasibility study on docetaxel/capecitabine/cisplatin (DCX) with chemoradiotherapy as adjuvant treatment for gastric cancer patients., Methods: Patients were scheduled to receive 2 cycles of DCX, followed by 50.4 Gy plus capecitabine as radiotherapy, followed by an additional 2-DCX cycles., Results: From the 40 enrolled patients, 26 (65%) completed treatment as per protocol and 14 (35%) discontinued with the treatment (patients' refusal: n=6; adverse events: n=8). There were 2 toxic deaths. Grade >3 toxicity was 12.1% before and 13.3% after chemoradiotherapy. Disease progression was documented in 11 (27.5%) patients., Conclusions: No further development of this regimen is justified on the basis of poor tolerability in patients.

This study investigates the clinical utility of squamous cell carcinoma antigen (SCC-Ag), circulating immune complexes (CIC), and immunoglobulins (IgA, IgG, IgM) in the diagnosis, monitoring, and prognosis of 117 squamous cell carcinoma of the head and neck (SCC-HN) patients having local and/or systemic treatment. Serum marker levels were measured in a prospective study. SCC-Ag was positive in 28.2% of patients, the CIC in 63.2%, the IgA in 11.1%, the IgG in 15.4%, and the IgM in 9.44%. Statistically significant correlation was found between the initial SCC-Ag levels and tumor localization, whereas the CIC levels were increasing significantly with progressing disease stages. It was also found that the significant decrease of SCC-Ag, IgA, and CIC levels at the end of treatment was correlated with an increased incidence of disease-free status. The initial values of IgG and the disease stage were significantly correlated with a favorable treatment outcome. The pretreatment elevated SCC-Ag and IgM serum values showed a significant trend to predict a disease progression. Using a Cox proportional hazards model the IgG serum values, the primary site, and the disease stage were significant predictors for time to progression. The significant decrease of SCC-Ag, IgA, and CIC values at the completion of treatment was correlated with an increased incidence of disease-free status. This study indicates that only the estimation of SCC-Ag and in some degree the IgM and/or IgG is a potential tool for monitoring the efficacy of treatment or disease recurrence in SCC-HN.

Twenty-two patients with supratentorial malignant gliomas were treated postoperatively with concurrent intracarotid chemotherapy and radiation therapy. There were seven women and 15 men with a median age of 56 years (range, 22-69) and median performance status (Karnofsky score) of 70 (range, 40-90). In all except two cases, histologic studies confirmed malignant glioma. All patients were irradiated with a cobalt 60 equipment. They should have received 45 Gy to the whole brain plus a 15-Gy coned-down boost to the tumor area. Chemotherapy consisted of cisplatin infusion at a dose of 60 mg/m2 on days 2, 22, and 42. Treatment was interrupted in two patients because of progressive disease and voluntary withdrawal in one patient each. In all, 63 courses of cisplatin infusion were administered, all at full dose. Two patients achieved a partial response, and nine had stable disease. Toxicities included nausea/vomiting in nine patients (41%) and transient hemiparesis, confusion, diarrhea, and thrombophlebitis in one patient each. Median time to progression was 26 weeks (range, 4-226+), and median survival was 58 weeks (range, 14-226+). In conclusion, the present study suggests that intracarotid cisplatin administered concurrently with radiation does not improve the therapeutic index in malignant gliomas.

Thirty-four patients with advanced malignant melanoma were treated with recombinant alpha-interferon (IFN) and chemotherapy consisting of carboplatin, vinblastine, and bleomycin (CVB). CVB was given for four cycles and IFN for 1 year or until progression. Of the 34 analyzed patients, 17 (50%) achieved an objective response, including two complete (6%) and 15 partial responses (44%). Responses were noted in cutaneous, lymph node, and pulmonary sites, with a median time to disease progression of 5 months (range, 3-20 months). The median survival from onset of therapy was 8 months (range, 1-22 months) for the 34 patients. Ninety-four percent of the patients experienced flu-like symptoms and 82% fatigue or weakness. Leukopenia grade 3-4 was observed in four patients (12%). There were two toxicity-related deaths (6%); one from bleomycin-induced pneumonitis and one from neutropenic sepsis. It is concluded that the addition of IFN to CVB regimen, in this study, showed no apparent advantage on response rates, disease-free interval, or survival. The observed treatment-related mortality was unacceptably high. IFN administered as maintenance therapy following CVB conferred no survival benefit.
