Randomized Controlled Trial
SELECT-2: a phase II, double-blind, randomized, placebo-controlled study to assess the efficacy of selumetinib plus docetaxel as a second-line treatment of patients with advanced or metastatic non-small-cell lung cancer.
Combination of selumetinib plus docetaxel provided clinical benefit in a previous phase II trial for patients with KRAS-mutant advanced non-small-cell lung cancer (NSCLC). The phase II SELECT-2 trial investigated safety and efficacy of selumetinib plus docetaxel for patients with advanced or metastatic NSCLC. ⋯ The primary end point (PFS) was not met. The higher ORR with SEL + DOC 75 did not translate into prolonged PFS for the overall or KRAS wild-type patient populations. No clinical benefit was observed with SEL + DOC in KRAS wild-type patients compared with docetaxel alone. No unexpected safety concerns were reported.

Interim PET after two ABVD cycles (iPET2) predicts treatment outcome in classical Hodgkin's lymphoma. To test whether an earlier assessment of chemosensitivity would improve the prediction accuracy, we launched a prospective, multicenter observational study aimed at assessing the predictive value of iPET after one ABVD (iPET1) and the kinetics of response assessed by sequential PET scanning. ⋯ The optimal tool to predict ABVD outcome in HL remains iPET2 because it distinguishes responders, whatever their time to response, from non-responders. However, iPET1 identified fast responders with the best outcome and might guide early treatment de-escalation in both early and advanced-stage HL.

Randomized Controlled Trial Multicenter Study
De-escalation strategies in HER2-positive early breast cancer (EBC): final analysis of the WSG-ADAPT HER2+/HR- phase II trial: efficacy, safety, and predictive markers for 12 weeks of neoadjuvant dual blockade with trastuzumab and pertuzumab ± weekly paclitaxel.
Response rates in HER2-overexpressing EBC treated with neoadjuvant chemotherapy and trastuzumab (T) have been improved by addition of pertuzumab (P). The prospective, phase II, neoadjuvant WSG-ADAPT HER2+/HR- trial assessed whether patients with strong early response to dual blockade alone might achieve pathological complete response (pCR) comparable to that of patients receiving dual blockade and chemotherapy. ⋯ Addition of taxane monotherapy to dual HER2 blockade in a 12-week neoadjuvant setting substantially increases pCR rates in HER2+/HR- EBC compared with dual blockade alone, even within early responders to dual blockade. Early non-response under dual blockade strongly predicts failure to achieve pCR.

Randomized Controlled Trial Multicenter Study
Overall survival analysis of EXAM, a phase III trial of cabozantinib in patients with radiographically progressive medullary thyroid carcinoma.
Primary analysis of the double-blind, phase III Efficacy of XL184 (Cabozantinib) in Advanced Medullary Thyroid Cancer (EXAM) trial demonstrated significant improvement in progression-free survival with cabozantinib versus placebo in patients with progressive medullary thyroid cancer (MTC). Final analysis of overall survival (OS), a key secondary endpoint, was carried out after long-term follow-up. ⋯ The secondary end point was not met in this final OS analysis from the trial of cabozantinib in patients with metastatic, radiographically progressive MTC. A statistically nonsignificant increase in OS was observed for cabozantinib compared with placebo. Exploratory analyses suggest that patients with RET M918T-positive tumors may experience a greater treatment benefit with cabozantinib.

The role of intraperitoneal (i.p.) chemotherapy in treating newly diagnosed advanced epithelial ovarian cancer (EOC) has been the subject of controversy for almost three decades. Three large intergroup phase III trials (GOG 104, 114, 172) have demonstrated a survival benefit associated with i.p. over intravenous (i.v.) therapy in advanced, low-volume EOC. ⋯ The hesitancy of clinicians to use i.p. therapy is likely attributed to higher toxicity, inconvenience, catheter complications, and clinical trial design issues. On the other hand, In a long-term follow-up report from these trials, we showed that the effect of i.p. chemotherapy extends beyond 10 years and that the more cycles of i.p. therapy portends for improved survival over similar cycles of i.v. therapy with younger patients having a higher likelihood of completing 6 cycles of i.p.
