Premenopausal women with early hormone-receptor positive (HR+) breast cancer receive 5â10 years of adjuvant endocrine therapy (ET) during which pregnancy is contraindicated and fertility may wane. The POSITIVE study investigates the impact of temporary ET interruption to allow pregnancy.
Methods
POSITIVE enrolled women with stage I-III HR + early breast cancer, â€42 years, who had received 18â30 months of adjuvant ET and wished to interrupt ET for pregnancy. Treatment interruption for up to 2 years was permitted to allow pregnancy, delivery and breastfeeding, followed by ET resumption to complete the planned duration.
Findings
From 12/2014 to 12/2019, 518 women were enrolled at 116 institutions/20 countries/4 continents. At enrolment, the median age was 37 years and 74.9 % were nulliparous. Fertility preservation was used by 51.5 % of women. 93.2 % of patients had stage I/II disease, 66.0 % were node-negative, 54.7 % had breast conserving surgery, 61.9 % had received neo/adjuvant chemotherapy. Tamoxifen alone was the most prescribed ET (41.8 %), followed by tamoxifen + ovarian function suppression (OFS) (35.4 %). A greater proportion of North American women were <35 years at enrolment (42.7 %), had mastectomy (59.0 %) and received tamoxifen alone (59.8 %). More Asian women were nulliparous (81.0 %), had node-negative disease (76.2%) and received tamoxifen + OFS (56.0 %). More European women had received chemotherapy (69.3 %).
Interpretation
The characteristics of participants in the POSITIVE study provide insights to which patients and doctors considered it acceptable to interrupt ET to pursue pregnancy. Similarities and variations from a regional, sociodemographic, disease and treatment standpoint suggest specific sociocultural attitudes across the world.The POSITIVE trial and this work are sponsored by the IBCSG in non-North American countries and by the Alliance for Clinical Trials in Oncology in North America, with collaboration of the Breast International Group (BIG) cooperative groups and US National Clinical Trials Network groups
Safety of pregnancy after breast cancer in young women with hormone receptor-positive disease: a systematic review and meta-analysis
Pattern of Rash, Diarrhea, and Hepatic Toxicities Secondary to Lapatinib and Their Association With Age and Response to Neoadjuvant Therapy: Analysis From the NeoALTTO Trial
Purpose We investigated the pattern of rash, diarrhea, and hepatic adverse events (AEs) secondary to lapatinib and their association with age and pathologic complete response (pCR) in the Neoadjuvant Lapatinib and/or Trastuzumab Treatment Optimisation (NeoALLTO) phase III trial.
Patients and Methods Patients with HER2-positive early breast cancer were randomly assigned to receive lapatinib (Arm A), trastuzumab (Arm B), or their combination (Arm C) for 6 weeks followed by the addition of paclitaxel for 12 weeks before surgery. We investigated the frequency and time to developing each AE according to age ( 50 v > 50 years) and their association with pCR in a logistic regression model adjusted for age, hormone receptors, tumor size, nodal status, planned breast surgery, completion of lapatinib administration, and treatment arm.
Results Only patients randomly assigned to arms A and C were eligible (n = 306). Younger patients ( 50 years) experienced significantly more rash compared with older patients (74.4% v 47.9%; P < .0001). Diarrhea and hepatic AEs were observed in 78.8% and 41.2% of patients, respectively, with no differences in rate or severity or time of onset according to age. Early rash (ie, before starting paclitaxel) was independently associated with a higher chance of pCR, mainly in patients older than 50 years (odds ratio [OR] = 3.76; 95% CI, 1.69 to 8.34) but not in those 50 years (OR = 0.92; 95% CI, 0.45 to 1.88; P for interaction = .01). No significant association was observed between pCR and diarrhea or hepatic AEs.
Conclusion Our results indicate that the frequency and clinical relevance of lapatinib-related rash is largely dependent on patient age
Systemic treatment of brain metastases in HER2-positive breast cancer: current status and future directions
Rituximab in lymphocyte-predominant Hodgkin disease
BACKGROUND:
Lymphocyte-predominant Hodgkin disease (LPHD) differs in biology and clinical behaviour from classic Hodgkin disease. Almost 100% of LPHD neoplastic cells express CD20 and thus rituximab could be effective; yet limited data are available.
PATIENTS AND METHODS:
We performed a retrospective analysis on patients with LPHD who were treated with rituximab at our institution to determine the magnitude of benefit offered by this drug.
RESULTS:
Seven patients were identified; 4 received the drug as single agent while the rest received it in combination with chemotherapy. All except 2 received the drug in the salvage setting. Response rate was 100% with 6 of 7 patients achieving complete remission. At a median follow-up of 2 years, 4 patients are still disease free while the rest relapsed at a median time of 27 months.
CONCLUSION:
Rituximab is effective in LPHD and should be considered; however, the optimal schedule remains to be determined
