ABSTRACT

BACKGROUND: SQUIRE demonstrated addition of necitumumab to gemcitabine and cisplatin significantly improved survival in patients with stage IV sq-NSCLC. Here, we report additional outcomes for the subpopulation of patients with tumor epidermal growth factor receptor (EGFR) protein expression. PATIENTS AND METHODS: Patients with pathologically confirmed stage IV sq-NSCLC were randomized 1:1 to receive a maximum of six 3-week cycles of gemcitabine (1250 mg/m(2) i.v., days 1 and 8) and cisplatin (75 mg/m(2) i.v., day 1) chemotherapy with or without necitumumab (800 mg i.v., days 1 and 8). Patients in the chemotherapy plus necitumumab group with no progression continued on necitumumab alone until disease progression or intolerable toxicity. SQUIRE included mandatory tissue collection. EGFR protein expression was detected by immunohistochemistry (IHC) in a central laboratory. Exploratory analyses were pre-specified for patients with EGFR protein expressing (EGFR > 0) and non-expressing (EGFR = 0) tumors. RESULTS: A total of 982 patients [90% of intention-to-treat (ITT)] had evaluable IHC results. The large majority of these patients (95%) had tumor samples expressing EGFR protein; only 5% had tumors without detectable EGFR protein. Overall survival (OS) for EGFR > 0 patients was significantly longer in the necitumumab plus gemcitabine-cisplatin group than in the gemcitabine-cisplatin group {stratified hazard ratio (HR) 0.79 [95% confidence interval (CI) 0.69, 0.92; P = 0.002]; median 11.7 months (95% CI 10.7, 12.9) versus 10.0 months (8.9, 11.4)}. Additionally, an OS benefit was seen in all pre-specified subgroups in EGFR > 0 patients. However, OS HR for EGFR = 0 was 1.52. Adverse events of interest with the largest difference between treatment groups in EGFR > 0 patients (Grade ≥3) were hypomagnesemia (10% versus <1%) and skin rash (6% versus <1%). CONCLUSIONS: In line with SQUIRE ITT, addition of necitumumab to gemcitabine-cisplatin significantly prolonged OS and was generally well tolerated in the subpopulation of patients with EGFR-expressing advanced sq-NSCLC. The benefit from addition of necitumumab to chemotherapy was not apparent in this analysis for the small subgroup of patients with non-EGFR-expressing tumors. CLINICAL TRIAL: NCT00981058.

ABSTRACT

While autonomy has gradually become a key concept in the doctor-patient relationship, truth-telling is far from being the norm in many countries in the world. Despite the general agreement on the benefits of open communication between physicians and cancer patients, there is still strong resistance against disclosure of cancer diagnosis and prognosis in many cultures. Although fear of causing psychological morbidity to patients and their reluctance to find out the truth are two main justifications of non-disclosure attitudes, there are other important contributing factors that need to be further explored and better understood including those related to the relatives, doctors and healthcare systems. Cultural disparities in attitudes towards truth-telling persist; however, these differences should not be used as excuses not to respect the rights and individual preferences of cancer patients by making assumptions based on their age, sex, type of cancer, language and/or cultural background.
