The diagnosis and management of uterine smooth muscle tumors with uncertain malignant potential (STUMP) is often challenging, and genomic data on these lesions as well as on uterine smooth muscle lesions are limited. We tested the hypothesis that genomic profile determination by array-CGH could split STUMP into a benign group with scarce chromosomal alterations akin to leiomyoma and a malignant group with high chromosomal instability akin to leiomyosarcoma. Array-CGH genomic profile analysis was conducted for a series of 29 cases of uterine STUMP. A group of ten uterine leiomyomas and ten uterine leiomyosarcomas served as controls. The mean age was 50 years (range, 24–85) and the follow-up ranged from 12 to 156 months (average 70 months). Since STUMP is a heterogenous group of tumors with genomic profiles that can harbor few to many chromosomal alterations, we compared genomic indices in leiomyomas and leiomyosarcomas and set a genomic index=10 threshold. Tumors with a genomic index <10 were classified as nonrecurring STUMPs and those with a genomic index >10 represented STUMPs with recurrences and unfavorable outcomes. Hence, the genomic index threshold splits the STUMP category into two groups of tumors with different outcomes: a group comparable to leiomyomas and another similar to leiomyosarcomas, but more indolent. In our STUMP series, genomic analysis by array-CGH is an innovative diagnostic tool for problematic smooth muscle uterine lesions, complementary to the morphological evaluation approach. We provide an improved classification method for distinguishing truly malignant tumors from benign lesions within the category of STUMP, especially those with equivocal morphological features.

To examine outcomes of neoadjuvant endocrine therapy in daily practice to inform decision making. We retrospectively selected 204 patients who received neoadjuvant endocrine therapy with T2 (≥30 mm) or T3 tumors, examining subsequent breast-sparing surgery and long-term outcomes. Neoadjuvant endocrine therapy was administered for 7.3 months (median) and breast-sparing surgery was achievable in 53% of patients. Smaller initial tumor size and modified version of the Scarff–Bloom and Richardson grades 1 to 2 were associated with breast-sparing surgery. Disease progression during treatment was 6.9%; actuarial risk of local relapse was 3% at 5 years and 15% at 10 years. Five- and 10-year metastasis relapse-free survival was 78% and 63%, respectively. Grade 3, negative progesterone receptors, and absence or slow response to neoadjuvant therapy were associated prognostic factors. These daily practice data provide important information about feasibility, efficacy, and long-term results of neoadjuvant endocrine therapy and can be used to inform patients for decision making between mastectomy and endocrine induction therapy.

Previous precision medicine studies have investigated conventional molecular techniques and/or limited sets of gene alterations. The aim of this study was to describe the impact of the next-generation sequencing of the largest panel of genes used to date in tumour tissue and blood in the context of institutional molecular screening programmes. DNA analysis was performed by next-generation sequencing using a panel of 426 cancer-related genes and by comparative genomic hybridization from formalin-fixed and paraffin-embedded archived tumour samples when available or from fresh tumour samples. Five hundred sixty-eight patients were enrolled. The median number of prior lines of treatment was 2 (range 0–9). The most common primary tumour types were lung (16.9%), colorectal (14.4%), breast (10.6%), ovarian (10.2%) and sarcoma (10.2%). The median patient age was 63 years (range 19–88). A total of 292 patients (51.4%) presented with at least one actionable genetic alteration. The 20 genes most frequently altered were TP53 , CDKN2A , KRAS , PTEN , PI3KCA , RB1 , APC , ERBB2 , MYC , EGFR , CDKN2B , ARID1A , SMAD4 , FGFR1 , MDM2 , BRAF , ATM , CCNE1 , FGFR3 and FRS2 . One hundred fifty-nine patients (28%) were included in early phase trials. The treatment was matched with a tumour profile in 86 cases (15%). The two main reasons for non-inclusion were non-progressive disease (31.5%) and general status deterioration (25%). Twenty-eight percent of patients presented with a growth modulation index (time to progression under the early phase trial treatment/time to progression of the previous line of treatment) >1.3. Extensive molecular profiling using high-throughput techniques allows for the identification of actionable mutations in the majority of cases and is associated with substantial clinical benefit in up to one in four patients.

Purpose Angiogenesis plays a crucial role in metastatic progression of soft tissue sarcomas (STS). Endothelial cells are the primary target of metronomic chemotherapy. We report the safety and the efficacy of metronomic chemotherapy in metastatic STS patients. Methods The medical charts of 26 metastatic STS patients treated at Institut Bergonie (Bordeaux, France) with metronomic etoposide (100 mg/day orally for 21 consecutive days, repeated every 4 weeks) were reviewed by two independent investigators. Results Median age was 49. All but three patients received prior treatment with doxorubicin and/or ifosfamide. One patient (4%) had partial response and 11 patients (42%) had stable disease for more than 24 weeks. The 6-month and the 1-year progression-free survival rates were 42% [95% CI: 23; 61] and 23% [95% CI: 7; 39], respectively. The 6-month and the 1-year overall survival rates were 69% [95% CI: 51; 87] and 31% [95% CI: 13; 49], respectively. Two patients experienced grade 4 febrile neutropenia and one of them died of sepsis. Conclusion In this series, metronomic etoposide was associated with significant clinical activity in STS. Further prospective investigations are necessary to identify those patients who are more likely to benefit from this strategy.

Olaparib was approved in 2014 by the European Medicines Agency (EMA) as maintenance treatment for patients with breast cancer gene (BRCA)-mutated platinum-sensitive relapsed high-grade epithelial ovarian cancer (EOC) following the results of the Study 19. We present the results of a national real-world study on the effectiveness of olaparib in relapsed BRCA-mutated EOC patients. Patients with EOC, peritoneal, and/or fallopian-tube cancer treated with olaparib in a French Center between May 2014 and March 2017 were included. The primary end-point of the study was progression-free survival. Of the 128 patients analyzed, 89 were treated according to the EMA label. The median progression-free survival was 17.0 months. The most common treatment-related toxicity was fatigue. Treatment-related myelodysplastic syndrome (n=5) and a second cancer (n=1) were diagnosed. In this real-life setting, olaparib confirmed its efficacy and safety profile, as previously shown in clinical trials.

Endometrial stromal sarcomas represent the second most common mesenchymal uterine tumor. The 2003 WHO classification distinguishes low-grade and undifferentiated endometrial stromal sarcomas with different prognoses. Endometrial stromal sarcomas are a genetically heterogeneous group of sarcomas harboring different cytogenetic anomalies. Recently, a fusion between the YWHAE and FAM22A/B genes subsequent to a t(10;17) (q22;p13) has been described in endometrial sarcomas with high-grade histology. We examined YWHAE rearrangements by FISH break-apart and RT-PCR in a series of 27 undifferentiated uterine stromal sarcoma without JAZF1 rearrangements. Immunohistochemistry (IHC) was carried out with a panel of antibodies (estrogen (ER) and progesterone (PR) receptors, CD10, Cyclin D1, β -catenin, p53, and Ki-67). We identified a subgroup of endometrial sarcomas with high-grade histology and uniform morphology harboring YWHAE rearrangements. FISH break-apart was interpretable in 20 cases (74%). Twelve cases (60%) showed <10% of tumor cells with a YWHAE rearrangement, 4 cases (20%) showed between 10 and ≤20%, and 4 (20%) >20%. RT-PCR was tested on 24/27 cases (88%) and 19 cases were interpretable (79%). Five cases (26%) showed a specific fusion transcript YWHAE–FAM22A/B sequence. The best concordance rate between FISH and RT-PCR (94%) was obtained with the threshold of 20% of cells with a YWHAE rearrangement. The YWHAE -rearranged cases showed high-grade morphology with uniform appearance, spindle or round epithelioid cells, low ER and PR, CD10 expression, and a high and diffuse positivity for Cyclin D1, p53, and nuclear β -catenin negativity. Cyclin D1 was the most sensitive marker for high-grade endometrial sarcomas with YWHAE rearrangement. All undifferentiated uterine sarcomas with pleomorphic appearances did not harbor any YWHAE rearrangements, except for one case. Overall, for endometrial sarcoma cases with high-grade morphology we recommend to test for YWHAE rearrangements by FISH break-apart, a cost- and time-efficient method, and to complete the investigation by RT-PCR in borderline cases.

Maintenance niraparib at an individualized starting dose (ISD) is established in platinum-sensitive recurrent ovarian cancer (PSROC). However, patients' perspectives on the burden of prolonged maintenance therapy have not been reported in prospective trials or routine practice. In the real-life multicenter NiQoLe study, patients with PSROC received ISD maintenance niraparib. The primary objective was to describe physician-reported adverse events (AEs) leading to treatment modification during the first 3 months. Secondary endpoints included patient-reported outcomes (symptomatic AEs using PRO-CTCAE, self-reported fatigue, and impact on daily activities/function using FACT-F) collected remotely weekly using a specifically designed electronic device. Most (80%) of 139 treated patients (median age = 70 years) began niraparib at 200 mg/day. Median treatment duration was 5.7 (range = 0.2-21.4) months. During the first 3 months, 86 patients (62%) required treatment modification (median = 27 days to modification). Physician-reported grade ≥3 niraparib-related AEs occurred in 34 patients (24%); 68 patients (49%) had treatment modification for AEs, predominantly thrombocytopenia. The most frequent patient-reported AEs (PRO-CTCAE) were fatigue, insomnia, constipation, and dry mouth. Self-reported AEs were severe in 66% of patients. At baseline, 33% of patients reported severe fatigue (FACT-F), which generally persisted during niraparib. Physicians systematically underestimated major patient-reported symptoms. In routine practice, niraparib dose modification was often required during the first 3 months despite individualized dosing. Physicians underestimated the burden of fatigue and symptomatic AEs. Digital self-reporting of AEs is feasible, provides patient-centered information complementing physician-reported AEs, and allows fuller appreciation of toxicity in real-world studies. NCT03752216.

Background We wished to estimate the proportion of patients with breast cancer eligible for an exclusive targeted intraoperative radiotherapy (TARGIT) and to evaluate their survival without local recurrence. Methods We undertook a retrospective study examining two cohorts. The first cohort was multicentric (G3S) and contained 7580 patients. The second cohort was monocentric (cohort 2) comprising 4445 patients. All patients underwent conservative surgery followed by external radiotherapy for invasive breast cancer (T0–T3, N0–N1) between 1980 and 2005. Within each cohort, two groups were isolated according to the inclusion criteria of the TARGIT A study (T group) and RIOP trial (R group). In the multicentric cohort (G3S) eligible patients for TARGIT A and RIOP trials were T1E and R1E subgroups, respectively. In cohort number 2, the corresponding subgroups were T2E and R2E. Similarly, non-eligible patients were T1nE, R1nE and T2nE, and R2nE. The eligible groups in the TARGIT A study that were not eligible in the RIOP trial (TE–RE) were also studied. The proportion of patients eligible for TARGIT was calculated according to the criteria of each study. A comparison was made of the 5-year survival without local or locoregional recurrence between the TE versus TnE, RE versus RnE, and RE versus (TE–RE) groups. Results In G3S and cohort 2, the proportion of patients eligible for TARGIT was, respectively, 53.2% and 33.9% according the criteria of the TARGIT A study, and 21% and 8% according the criteria of the RIOP trial. Survival without five-year locoregional recurrence was significantly different between T1E and T1nE groups (97.6% versus 97% [log rank =0.009]), R1E and R1nE groups (98% versus 97.1% [log rank =0.011]), T2E and T2nE groups (96.6% versus 93.1% [log rank <0. 0001]) and R2E and R2nE groups (98.6% versus 94% [log rank =0.001]). In both cohorts, no significant difference was found between RE and (TE–RE) groups. Conclusions Almost 50% of T0-2 N0 patients could be eligible for TARGIT.
