Background Metastatic renal cell carcinoma (mRCC) patients receiving first-line sunitinib typically survive >2 yr, with chronic treatment sometimes extending to ≥6 yr. Objective To analyze long-term safety with sunitinib in mRCC patients. Design, setting, and participants Data were pooled from 5739 patients in nine trials, comprising seven phase II studies, a phase III study, and an expanded-access trial in various treatment settings (e.g. cytokine refractory or treatment-naïve). Outcome measurements and statistical analysis Interval and cumulative time-period analyses evaluated the incidence of treatment-related adverse events (TRAEs) for up to 6 yr, in the overall population and in those with long-term (≥2 yr) sunitinib treatment. Results and limitations Among long-term patients (n=807), most TRAEs occurred initially in the first year and then decreased in frequency; TRAEs following this pattern included decreased appetite, diarrhea, dysgeusia, dyspepsia, fatigue, hypertension, mucosal inflammation, nausea, and stomatitis. However, hypothyroidism increased by interval analysis from 6% at 0-<6 mo to 42% at 5-<6 yr and by cumulative analysis from 14% at 0-<1 yr to 36% over 6 yr. Grade 3/4 TRAEs in long-term patients peaked during the first year and then steadily decreased. The overall population displayed only minor differences from long-term patients, with no clinically significant differences between grade ≥3 TRAE profiles (<5% difference in incidence rates at all intervals). Limitations included retrospective design, assessment variability, lack of pharmacokinetic data, and absence of baseline characteristics for long-term patients. Conclusions Prolonged sunitinib was not associated with new types or increased severity of TRAEs. Except hypothyroidism, toxicity was not cumulative. Patient summary More than 800 mRCC patients received sunitinib for between 2 and 6 yr without experiencing new or more severe treatment-related toxicity. Clinicians may be able to prescribe chronic sunitinib treatment for as long as patients continue to derive clinical benefit, without untoward additional risk. © 2015 European Association of Urology.

Objective: To assess local recurrence, disease-free survival, and overall survival in magnetic resonance imaging (MRI)-predicted good prognosis tumors treated by surgery alone. Background: The MERCURY study reported that high-resolution MRI can accurately stage rectal cancer. The routine policy in most centers involved in the MERCURY study was primary surgery alone in MRI-predicted stage II or less and in MRI "good prognosis" stage III with selective avoidance of neoadjuvant therapy. PATIENTS and Methods: Data were collected prospectively on all patients included in the MERCURY study who were staged as MRI-defined "good" prognosis tumors. "Good" prognosis included MRI-predicted safe circumferential resection margins, with MRI-predicted T2/T3a/T3b (less than 5 mm spread from muscularis propria), regardless of MRI N stage. None received preoperative or postoperative radiotherapy. Overall survival, disease-free survival, and local recurrence were calculated. Results: Of 374 patients followed up in the MERCURY study, 122 (33%) were defined as "good prognosis" stage III or less on MRI. Overall and disease-free survival for all patients with MRI "good prognosis" stage I, II and III disease at 5 years was 68% and 85%, respectively. The local recurrence rate for this series of patients predicted to have a good prognosis tumor on MRI was 3%. Conclusions: The preoperative identification of good prognosis tumors using MRI will allow stratification of PATIENTS and better targeting of preoperative therapy. This study confirms the ability of MRI to select patients who are likely to have a good outcome with primary surgery alone. © 2011 Lippincott Williams & Wilkins.

The randomized, double-blinded Royal Marsden Tamoxifen Breast Cancer Prevention Trial in healthy high-risk women started in 1986 and is still blinded. Eligible participants (n = 2,471) were randomly assigned to tamoxifen (20 mg/d) or placebo for 8 years. Analysis in 2006 showed a 30% risk reduction of estrogen receptor (ER)-positive invasive breast cancer mostly in the posttreatment period. Biomarker analysis in this population may identify any subgroup-specific preventive effects tamoxifen. After a median follow-up of 18.4 years, 242 patients had developed invasive cancer, 134 on placebo and 108 on tamoxifen. From these, 180 tissue blocks were available and ER, progesterone receptor (PgR), Ki67, HER2, and EGFR were immunohistochemically analyzed. A 32% reduction in ER+ and PgR+ invasive cancers resulted after 8 years of treatment. Quantitative levels of ER and PgR were lower in the tamoxifen-treated group, significantly so for ER (P = 0.001). These lower ER levels were restricted to the posttreatment period (P = 0.018). Among the ER+ group, there was a similar proportional decrease in PgR+ and PgR- tumors by tamoxifen. The median levels of Ki67 were similar in both arms. The numbers of HER2-positive and EGFR-positive cancers were higher in the tamoxifen arm but not significantly so. In conclusion, the preventive effects of tamoxifen result in reduced ER-positive but not ER-negative tumors and reduced ER expression in the ER-positive cases largely confined to the posttreatment period. Overall reductions in PgR expression are explained by lower frequency of ER-positive cases. Impact on Ki67, HER2, and EGFR was modest. ©2017 AACR.

Results The median progression-free survival was 18.3 months in the lenvatinib group and 3.6 months in the placebo group (hazard ratio for progression or death, 0.21; 99% confidence interval, 0.14 to 0.31; P<0.001). A progression-free survival benefit associated with lenvatinib was observed in all prespecified subgroups. The response rate was 64.8% in the lenvatinib group (4 complete responses and 165 partial responses) and 1.5% in the placebo group (P<0.001). The median overall survival was not reached in either group. Treatment-related adverse effects of any grade, which occurred in more than 40% of patients in the lenvatinib group, were hypertension (in 67.8% of the patients), diarrhea (in 59.4%), fatigue or asthenia (in 59.0%), decreased appetite (in 50.2%), decreased weight (in 46.4%), and nausea (in 41.0%). Discontinuations of the study drug because of adverse effects occurred in 37 patients who received lenvatinib (14.2%) and 3 patients who received placebo (2.3%). In the lenvatinib group, 6 of 20 deaths that occurred during the treatment period were considered to be drug-related.Conclusions Lenvatinib, as compared with placebo, was associated with significant improvements in progression-free survival and the response rate among patients with iodine-131-refractory thyroid cancer. Patients who received lenvatinib had more adverse effects. (Funded by Eisai; SELECT number, NCT01321554.) Copyright © 2015 Massachusetts Medical Society.Background Lenvatinib, an oral inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, fibroblast growth factor receptors 1 through 4, platelet-derived growth factor receptor á, RET, and KIT, showed clinical activity in a phase 2 study involving patients with differentiated thyroid cancer that was refractory to radioiodine (iodine-131).Methods In our phase 3, randomized, double-blind, multicenter study involving patients with progressive thyroid cancer that was refractory to iodine-131, we randomly assigned 261 patients to receive lenvatinib (at a daily dose of 24 mg per day in 28-day cycles) and 131 patients to receive placebo. At the time of disease progression, patients in the placebo group could receive open-label lenvatinib. The primary end point was progression-free survival. Secondary end points included the response rate, overall survival, and safety.

Background: Bereaved relatives are considered to be a vulnerable group and there is debate as to whether it is ethical to engage them in research at a time that can be difficult for them.Aim: We conducted a cross-sectional study using cognitive interviewing with the aim of exploring the acceptability of a mortality follow-back survey among bereaved relatives of recently deceased cancer patients to inform the development of a large-scale survey about end-of-life care.Results: Thirty-three next-of-kin of recently deceased cancer patients were invited to participate in a face-to-face interview, or to complete a postal questionnaire. At the end, they were asked about their views of engaging in the study. Nine bereaved relatives participated in a face-to-face interview and 11 completed the postal questionnaire. Eleven relatives reported it was helpful to take part in the study; of these, six did not consider it distressing, and five stated whilst it had been distressing it had been helpful. Thoughts about bringing back memories, altruism and therapeutic value emerged.Conclusions: We have new evidence that although engaging in follow-back surveys can evoke distress, many participants report it to be a positive experience. We therefore believe that this approach is acceptable when conducted sensitively. © 2011 The Author(s).

Oesophageal cancer is the eighth most common cancer diagnosed worldwide, with almost half a million new cases diagnosed each year. Despite improvements in surgical and radiotherapy techniques and refinements of chemotherapeutic regimens, long-term survival, even from localized oesophageal cancer, remains poor. Surgical resection alone remains the standard approach for very early stage disease (stage I), but whilst surgery remains fundamental to the treatment of stage IIIII resectable adenocarcinoma, multimodality therapy with chemotherapy or chemoradiation (CRT) is internationally accepted as the standard of care. Data from two large, randomized phase III trials support the use of perioperative combination chemotherapy in lower oesophageal and oesophagogastric junction adenocarcinomas, but the contribution of the adjuvant therapy is uncertain. There are conflicting data from randomized studies of a purely neoadjuvant approach; however, recent meta-analyses have demonstrated that chemotherapy or CRT given prior to radical surgery improves survival in patients with adenocarcinoma of the oesophagus. Neoadjuvant CRT but not chemotherapy alone is also beneficial for patients with squamous cell carcinoma. Definitive CRT has emerged as a useful option for the treatment of resectable squamous cell carcinoma of the oesophagus, avoiding potential surgical morbidity and mortality for most patients, with salvage surgery reserved for those with persistent disease.In this review, we focus on the pharmacotherapy of resectable oesophageal and oesophagogastric junction cancers and how clinical trials and meta-analyses inform current clinical practice. © 2011 Adis Data Information BV.

Background Hypertension (HTN) is an on-target effect of the vascular endothelial growth factor pathway inhibitor, sunitinib. We evaluated the association of sunitinib-induced HTN with antitumor efficacy and HTN-associated adverse events in patients with metastatic renal cell carcinoma. Methods This retrospective analysis included pooled efficacy (n = 544) and safety (n = 4917) data from four studies of patients with metastatic renal cell carcinoma who were treated with sunitinib 50 mg/d administered on a 4-week-on 2-week-off schedule (schedule 4/2). Blood pressure (BP) was measured in the clinic on days 1 and 28 of each 6-week cycle. Progression-free survival (PFS) and overall survival (OS) were estimated using Kaplan-Meier methods; hazard ratios (HRs) for survival were also estimated by a Cox proportional hazards models using HTN as a time-dependent covariate. Efficacy outcomes were compared between patients with and without HTN (maximum systolic BP [SBP] ≥140 mm Hg or diastolic BP [DBP] ≥90 mm Hg). Adverse events were also compared between patients with and without HTN (mean SBP ≥140 mm Hg or mean DBP ≥90 mm Hg). All P values were two-sided. Results Patients with metastatic renal cell carcinoma and sunitinib-induced HTN defined by maximum SBP had better outcomes than those without treatment-induced HTN (objective response rate: 54.8% vs 8.7%; median PFS: 12.5 months, 95% confidence interval [CI] = 10.9 to 13.7 vs 2.5 months, 95% CI = 2.3 to 3.8 months; and OS: 30.9 months, 95% CI = 27.9 to 33.7 vs 7.2 months, 95% CI = 5.6 to 10.7 months; P <. 001 for all). Similar results were obtained when comparing patients with vs without sunitinib-induced HTN defined by maximum DBP. In a Cox proportional hazards model using HTN as a time-dependent covariate, PFS (HR of disease progression or death =. 603, 95% CI =. 451 to. 805; P <. 001) and OS (HR of death =. 332, 95% CI =. 252 to. 436; P <. 001) were improved in patients with treatment-induced HTN defined by maximum SBP; OS (HR of death =. 585, 95% CI =. 463 to. 740; P <. 001) was improved in patients with treatment-induced HTN defined by maximum DBP, but PFS was not. Few any-cause cardiovascular, cerebrovascular, ocular, and renal adverse events were observed. Rates of adverse events were similar between patients with and without HTN defined by mean SBP; however, hypertensive patients had somewhat more renal adverse events (5% vs 3%; P =. 013). Conclusions In patients with metastatic renal cell carcinoma, sunitinib-associated HTN is associated with improved clinical outcomes without clinically significant increases in HTN-associated adverse events, supporting its viability as an efficacy biomarker. © The Author 2011.

Background:We report final results with extended follow-up from a global, expanded-access trial that pre-regulatory approval provided sunitinib to metastatic renal cell carcinoma (mRCC) patients, ineligible for registration-directed trials.Methods:Patients ⩾18 years received oral sunitinib 50 mg per day on a 4-weeks-on–2-weeks-off schedule. Safety was assessed regularly. Tumour measurements were scheduled per local practice.Results:A total of 4543 patients received sunitinib. Median treatment duration and follow-up were 7.5 and 13.6 months. Objective response rate was 16% (95% confidence interval (CI): 15–17). Median progression-free survival (PFS) and overall survival (OS) were 9.4 months (95% CI: 8.8–10.0) and 18.7 months (95% CI: 17.5–19.5). Median PFS in subgroups of interest: aged ⩾65 years (33%), 10.1 months; Eastern Cooperative Oncology Group performance status ⩾2 (14%), 3.5 months; non-clear cell histology (12%), 6.0 months; and brain metastases (7%), 5.3 months. OS was strongly associated with the International Metastatic Renal-Cell Carcinoma Database Consortium prognostic model (n=4065). The most common grade 3/4 treatment-related adverse events were thrombocytopenia (10%), fatigue (9%), and asthenia, neutropenia, and hand–foot syndrome (each 7%).Conclusion:Final analysis of the sunitinib expanded-access trial provided a good opportunity to evaluate the long-term side effects of a tyrosine kinase inhibitor used worldwide in mRCC. Efficacy and safety findings were consistent with previous results.British Journal of Cancer advance online publication, 18 June 2015; doi:10.1038/bjc.2015.196 © 2015 Cancer Research UK

Background:DNA mismatch repair deficiency is present in a significant proportion of a number of solid tumours and is associated with distinct clinical behaviour.Methods:To identify the therapeutic agents that might show selectivity for mismatch repair-deficient tumour cells, we screened a pair of isogenic MLH1-deficient and MLH1-proficient tumour cell lines with a library of clinically used drugs. To test the generality of hits in the screen, selective agents were retested in cells deficient in the MSH2 mismatch repair gene.Results:We identified cytarabine and other related cytosine-based nucleoside analogues as being selectively toxic to MLH1 and MSH2-deficient tumour cells. The selective cytotoxicity we observed was likely caused by increased levels of cellular oxidative stress, as it could be abrogated by antioxidants.Conclusion:We propose that cytarabine-based chemotherapy regimens may represent a tumour-selective treatment strategy for mismatch repair-deficient cancers. © 2013 Cancer Research UK.
