Current evidence suggests many health benefits from physical activity during and post cancer treatments. Additional studies are needed in cancer diagnoses other than breast and with a focus on survivors in greatest need of improvements for the health outcomes of interest.

Baseline BIRS scores were similar across intervention and lymphedema status. Significantly greater improvement in BIRS total score was observed from baseline to 12 months in treatment vs. control participants (12.0 vs. 2.0%; P < 0.0001). A differential impact of the intervention on the Strength and Health subscale was observed for older women (>50 years old) in the treatment group (P = 0.03). Significantly greater improvement was observed in bench and leg press among treatment group when compared to control group participants, regardless of lymphedema. Observed intervention effects were independent of observed strength and QOL changes. Twice-weekly strength training positively impacted self-perceptions of appearance, health, physical strength, sexuality, relationships, and social functioning. Evidence suggests the intervention was beneficial regardless of prior diagnosis of lymphedema. Strength and QOL improvements did not mediate the observed intervention effects.

BACKGROUND: There is a need to better describe and understand the prevalence of breast cancer treatment-related adverse effects amenable to physical therapy and rehabilitative exercise. Prior studies have been limited to single issues and lacked long-term follow-up. The Pulling Through Study provides data on prevalence of adverse effects in breast cancer survivors followed over 6 years. METHODS: A population-based sample of Australian women (n ¼ 287) diagnosed with invasive, unilateral breast cancer was followed for a median of 6.6 years and prospectively assessed for treatment-related complications at 6, 12, and 18 months and 6 years after diagnosis. Assessments included postsurgical complications, skin or tissue reaction to radiation therapy, upper-body symptoms, lymphedema, 10% weight gain, fatigue, and upper-quadrant function. The proportion of women with positive indication for each complication and 1 or more complication was estimated using all available data at each time point. Women were only considered to have a specific complication if they reported the highest 2 levels of the Likert scale for self-reported issues. RESULTS: At 6 years after diagnosis, more than 60% of women experienced 1 or more side effects amenable to rehabilitative intervention. The proportion of women experiencing 3 or more side effects decreased throughout follow-up, whereas the proportion experiencing no side effects remained stable around 40% from 12 months to 6 years. Weight gain was the only complication to increase in prevalence over time. CONCLUSIONS: These data support the development of a multidisciplinary prospective surveillance approach for the purposes

PurposeTenosynovial giant cell tumor (TGCT), a rare locally aggressive neoplasm of the synovium of joints and tendon sheaths, is associated with joint destruction, inflammation, pain, and swelling, in part due to colony-stimulating factor 1 receptor–bearing macrophages recruited to the tumor by genetic elevation of colony-stimulating factor 1 activity. The most common treatment is surgery, although promising pharmacologic treatments are in development. Patient-reported outcome (PRO) instruments are critical end points in demonstrating the clinical relevance of standard oncologic outcome measures and the overall impact of novel pharmacologic therapies in nonmalignant neoplastic conditions such as TGCT. The content validity of PROs relevant to patients with TGCT has not been formally investigated, and instruments to evaluate such outcomes do not exist for this condition.MethodsPRO instruments of potential relevance were evaluated by using a literature review and by clinical and PRO experts. Patients with TGCT were recruited through clinical sites and the Internet for participation in qualitative research interviews to identify predominant symptoms and to test the relevance and content validity of several PRO measures. Select PRO measures were included in a Phase I clinical trial, and preliminary results of the PRO end points are reported descriptively.FindingsOf the 22 subjects who participated in qualitative interviews, 73% were female, and their mean age was 42.5 years (range, 27–56 years). The TGCTs (19 diffuse and 3 localized) were located in the knee (n = 15), hip (n = 3), ankle (n = 2), elbow (n= 1), and forearm (n = 1). The most common symptoms cited were pain (82%), swelling (86%), stiffness (73%), reduced range of motion (64%), and joint instability (64%), which were consistent with clinical expert input and with the content of instruments chosen by PRO experts. The worst pain numeric rating scale, Patient Reported Outcomes Measurement Information System physical functioning items, and the Western Ontario and McMaster Universities Osteoarthritis Index, as well as a worst stiffness numeric rating scale developed for TGCT, were confirmed as meaningful measures of TGCT patient symptoms and were well understood in qualitative interviews. Results from the Phase I trial showed trends of improvement in both pain and stiffness over time.ImplicationsThis study is the first to gather information directly from patients with TGCT regarding their symptom experiences. Pain, stiffness, and physical functioning are important treatment outcomes in patients with TGCT. We have identified content-valid PRO measures of these concepts, which are included in an ongoing Phase III TGCT clinical trial with pexidartinib (PLX3397) (NCT02371369).

Oncologists limited the dosing of chemotherapy because of CIPN in a significant proportion of paclitaxel recipients, most frequently in those who received a weekly regimen. Patients who had their dose reduced or discontinued received significantly less cumulative chemotherapy than planned. The implications of these DL CIPN events on treatment outcomes must be investigated.
