Purpose Intravenous trastuzumab, pertuzumab, and docetaxel are first-line standard of care for patients with HER2-positive metastatic breast cancer (mBC). MetaPHER is the first study assessing the safety and tolerability of subcutaneous trastuzumab plus intravenous pertuzumab and chemotherapy in a global patient population with HER2-positive mBC. Methods In this open-label, single-arm, multicenter, phase 3b study, eligible patients were ≥ 18 years old with histologically/cytologically confirmed previously untreated HER2-positive mBC. All received ≥ 1 subcutaneous trastuzumab 600 mg fixed dose plus intravenous pertuzumab (loading dose: 840 mg/kg; maintenance: 420 mg/kg) and docetaxel (≥ 6 cycles; initial dose 75 mg/m2) every 3 weeks. The primary objective was safety and tolerability; secondary objectives included efficacy. Results At clinical cutoff, 276 patients had completed the study; median duration of follow-up was 27 months. The most common any-grade adverse events were diarrhea, alopecia, and asthenia; the most common grade ≥ 3 events were neutropenia, febrile neutropenia, and hypertension. There were no cardiac deaths and mean left ventricular ejection fraction was stable over time. Median investigator-assessed progression-free survival was 18.7 months; objective response rate was 75.6%. Conclusions Safety and efficacy with subcutaneous trastuzumab plus intravenous pertuzumab and docetaxel in mBC are consistent with historical evidence of intravenous trastuzumab with this combination. Findings further support subcutaneous administration not affecting safety/efficacy profiles of trastuzumab in HER2-positive BC with increased flexibility in patient care. A fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection has recently been approved for the treatment of HER2-positive early/mBC, further addressing the increasing relevance of and need for patient-centric treatment strategies.

Introduction: Penile cancer is rare, and data on prognostic factors of the disease are scarce. The aim of the study was to assess prognostic factors in patients undergoing lymphadenectomy for penile cancer. Material and Methods: Ninety-eight men who underwent lymphadenectomy for penile cancer were enrolled in the study. Progression-free survival and overall survival were assessed. Results: Five-year progression-free survival and overall survival were 0.6651 (95% CI: 0.5151-0.7783) and 0.5516 (95% CI: 0.4412-0.6488), respectively. Multivariate analysis showed that the factors that reduce progression-free survival include delay of lymphadenectomy by more than 3 months after diagnosis (p = 0.045) and involvement of non-inguinal lymph nodes (N0 vs. affected lymph nodes other than superficial inguinal, p = 0.0004; superficial inguinal vs. others, p = 0.001). Factors deteriorating overall survival include high grade (G1 vs. G2, p = 0.0072, and G1 vs. G3, p = 0.0347), more than one lymph node affected (p = 0.001) and crossing the lymph node capsule (p = 0.034). Conclusions: The factors worsening the prognosis in patients with penile cancer after lymphadenectomy include delayed lymphadenectomy, involvement of lymph nodes other than the superficial inguinal, involvement of more than one lymph node, crossing the lymph node capsule, and high grade.
The study aimed to evaluate grade migration and prognosis depending on pathologic features in patients with prostate cancer treated with radical external beam radiotherapy. The study included 139 patients with an initial Gleason score of 7 (3+4 or 4+3) i.e., Grade Group 2-3 (GG2-GG3) treated between 2008 and 2013. The clinical outcome was assessed with respect to biochemical control (BC) and biochemical disease-free survival (bDFS). After re-evaluation, the majority of patients (96 patients -69%) were up-graded from GG2-3. Finally, there were 4 patients (3%) with grade GG1, 12 patients (9%) -GG2, 27 patients (19%) -GG3, 51 patients (37%) -GG4 and 45 patients (32%) -GG5. In 42 patients (30%) a cribriform pattern was observed. Among the analyzed factors only the GGs were important for BC (p = 0.011) and the cribriform pattern was of borderline significance (p = 0.06). The 5-year biochemical control was 100% in GG1-3 and 84% in GG4-5. The 5-year biochemical control was 81% and 93%, if cribriform or no cribriform pattern was detected, respectively. In conclusion, re-evaluation and verification of pathology specimens in accordance with contemporary rules upgraded the Gleason score in the majority of patients. The aggressive behavior of prostate cancer starts to occur from GG 4. Cribriform pattern almost tripled the biochemical failure rate.
Background Previous trials showed that fixed-dose subcutaneous trastuzumab and hyaluronidase-oysk (Herceptin Hylecta™; H SC) was non-inferior to weight-based intravenous trastuzumab (Herceptin®; H IV) in terms of pathologic complete response and serum trough concentration in HER2-positive early breast cancer (BC), with a comparable safety profile (NCT00950300), and demonstrated a compelling patient (pt) preference for H SC (NCT01401166). IV pertuzumab (PERJETA®; P IV) + H IV + docetaxel (D IV) was also shown to significantly improve progression-free survival (PFS) and overall survival vs. placebo + H IV + D IV in HER2-positive metastatic BC (NCT00567190). Here we report results from the final analysis of MetaPHER (NCT02402712), the largest study to evaluate safety and tolerability of first-line H SC + P IV + D IV for HER2-positive metastatic/locally advanced BC. Earlier analyses have been reported (Kümmel SABCS 2016; P4-21-42; Kümmel ESMO 2018; 323P). Methods Pts were ≥18-year-old females who had received no previous systemic non-hormonal anticancer therapy for their disease, had an Eastern Cooperative Oncology Group performance status of 0 or 1, and a left ventricular ejection fraction (LVEF) ≥50%. Brain metastases and concomitant hormone therapy were allowed. Pts received 600 mg H SC + 840 mg loading/420 mg maintenance doses of P IV + ≥6 cycles of D IV (75 mg/m2→100 mg/m2; >6 cycles were given at the investigator’s discretion) every 3 weeks until disease progression, unacceptable toxicity, withdrawal of consent, death, or predefined study end. The primary objective was to evaluate safety and tolerability. Adverse events (AEs) were graded per National Cancer Institute - Common Terminology Criteria for Adverse Events version 4.0; left ventricular systolic dysfunction (LVSD) was classified according to the New York Heart Association Functional Classification system. Safety results are descriptive. Exploratory efficacy endpoints were PFS and objective response rate (ORR). Results Four hundred eighteen pts were enrolled; 412 were treated and analyzed for safety, and 160 remained on treatment at study end. Data cutoff was May 23, 2019 with median follow-up of 27 months (max. 45 months). Baseline demographics were similar to the interim analysis. Median cycles of H SC, P IV, and D IV were 22.0, 21.5, and 6.0, respectively (some discontinued P IV due to toxicity but remained on H SC per the protocol). Most pts experienced ≥1 any-grade AE (406; 98.5%); 221 (53.6%), grade ≥3 AEs; 107 (26.0%), serious AEs; 87 (21.1%), AEs leading to withdrawal from any study treatment; 87 (21.1%), investigator-reported administration-related and local injection-site reactions (21 [5.1%] H SC-related). There were 87 deaths (21.1% of pts): 73 (17.7%) from disease progression, nine (2.2%) due to AEs, and five (1.2%) due to other causes after treatment discontinuation. Three pts (0.7%) experienced grade ≥3 cardiac AEs, and one (0.2%) a serious AE suggestive of congestive heart failure. Of the 396 pts with LVEF measurements at baseline and ≥1 post-baseline visit, 40 (10.1%) had LVEF drops (to <50% and ≥10% points from baseline; the majority were asymptomatic, grade 1-2, and did not lead to study drug discontinuation); only two (0.5%) had symptomatic LVSD. There were no cardiac deaths. Median investigator-assessed PFS was 18.7 months (234 events [56.8%]). The ORR was 75.6% (95% CI 70.6-80.1; 254/336 pts with measurable disease at baseline); the clinical benefit rate was 92.0% (309 pts). Conclusion The safety profile of first-line H SC + P IV + D IV for HER2-positive advanced BC was consistent with the known safety profile of H IV + P IV + D IV. No new safety signals were identified. Efficacy data were supportive of historical reports of H IV + P IV + D IV.
