Increased numbers of tumour infiltrating T‑cells have long been associated with a better prognosis in ovarian cancer, which has led to the general assumption of a relevant impact of T‑cellular anti-tumour immunity in this disease. As a consequence of this knowledge, a multitude of immunologic therapies has emerged over the past years. Although some reports could evidence a successful induction of anti-tumour T‑cells, in general, these attempts did not translate into clinically significant activity. As has already been shown in other tumour entities, immune checkpoint blockade – mainly antibodies directed against PD-1 and PD-L1 – could possibly become a real “game changer” in ovarian cancer in the future. © 2016, The Author(s).

Background: Induction chemotherapy incorporating docetaxel, cisplatin and 5- fluorouracil before radiotherapy may improve the outcome of patients with advanced head and neck cancer. Nevertheless, the addition of docetaxel increases hematological toxicity and infectious complications. Therefore, genetic markers predicting toxicity and efficacy of this treatment regimen may help to identify patients, who would have the most benefit from this intensive treatment. Methods: A cohort of 78 patients with advanced head and neck cancer treated with induction chemotherapy was assessed for clinical outcome and toxicity during treatment with curative intention. Genetic polymorphisms primary associated with treatment efficacy (ERCC2-rs13181, rs1799793, ERCC1-rs3212986, rs11615, XRCC1-rs25487) or with docetaxel caused toxicity (CYP39A1-rs7761731, SLCO1B3-rs11045585) were evaluated in all patients. The results of these analyses were correlated with the clinical outcome of the patients (loco regional control, progression free survival, overall survival) and treatment related toxicity during induction chemotherapy. Results: Median progression free survival and overall survival was 20 and 31 months in an intention to treat analysis, respectively. Overall response rate to induction chemotherapy was high with 78.1 % of all patients. None of the polymorphisms tested was associated with the clinical outcome of the patients. Genotype A of the CYP39A1 rs7761731 polymorphism was associated with a higher incidence of leucopenia and infections or death during induction chemotherapy. Conclusions: Intensive induction chemotherapy results in a high response rate in the majority of patients. None of the polymorphisms tested was associated with the clinical outcome of the patients. The CYP39A1 polymorphism rs7761731 may help to identify patients at high risk for treatment related toxicity. © 2015 Melchardt et al.
